PART I

ITEM 1.BUSINESS
 
Introduction


Mueller Industries, Inc. (the Company) is a leading manufacturer of copper, brass, aluminum, and plastic products.  The range of these products we manufacture is broad:  copper tube and fittings; line sets; brass and copper alloy rod, bar, and shapes; aluminum and brass forgings; aluminum impact extrusions; PEX plastic fittingstube and valves;fittings; refrigeration valves and fittings; compressed gas valves; fabricated tubular products; pressure vessels; steel nipples; and steel nipples.insulated flexible duct systems.  We also resell imported brass and plastic plumbing valves, plastic fittings, malleable iron fittings, faucets, and plumbing specialty products.  Our operations are located throughout the United States and in Canada, Mexico, Great Britain, South Korea, the Middle East, and China.  The Company was incorporated in Delaware on October 3, 1990.


During the first quarter of 2016, we made changes to our management reporting structure as a result of a change in the way the Chief Executive Officer, who serves as the Chief Operating Decision Maker, manages and evaluates the business, makes key operating decisions, and allocates resources.  Previously, we had two reportable segments: Plumbing & Refrigeration and OEM.  During the first quarter, we realigned our operating segments into three reportable segments: Piping Systems, Industrial Metals, and Climate.  The changes to the reporting structure resulted from management's decision to operationally separate certain businesses in order to enhance the level of focus on those businesses.  This included the appointment of separate management teams.  In addition, as a result of several acquisitions, we separated certain businesses with similar characteristics to create the Industrial Metals and Climate segments.  These businesses were previously aggregated within the OEM segment.  Management has recast certain prior year amounts to conform to the current year presentation. Each of theour reportable segments is composed of certain operating segments that are aggregated primarily by the nature of products offered. These are the Piping Systems, Industrial Metals, and Climate segments.


Certain administrative expenses and expenses related primarily to retiree benefits at inactive operations are combined into the Corporate and Eliminations classification.  


Financial information concerning segments and geographic information appears under "NoteNote 3 – Segment Information"Information in the Notes to Consolidated Financial Statements, which is incorporated herein by reference.

The union agreements at the Company'sCompany’s U.K. and Mexico operations are renewed annually.  The Company expects to renew its union contracts without material disruption ofto its operations.


Raw Material and Energy Availability


A substantial portion of our base metal requirements (primarily copper) is normally obtained through short-term supply contracts with competitive pricing provisions (for cathode) and the open market (for scrap).  Other raw materials used in the production of brass, including brass scrap, zinc, tin, and lead are obtained from zinc and lead producers, open-market dealers, and customers with brass process scrap.  Raw materials used in the fabrication of aluminum and plastic products are purchased in the open market from major producers.

5

Adequate supplies of raw material have historically been available to us from primary producers, metal brokers, and scrap dealers.  Sufficient energy in the form of natural gas, fuel oils, and electricity is available to operate our production facilities.  While temporary shortages of raw material and fuels may occur occasionally, to date they have not materially hampered our operations.


Our copper tube facilities can accommodate both refined copper and certain grades of copper scrap as the primary feedstock.  The Company has commitments from refined copper producers for a portion of its metal requirements for 2017.2020.  Adequate quantities of copper are currently available.  While we will continue to react to market developments, resulting pricing volatility or supply disruptions, if any, could nonetheless adversely affect the Company.


Environmental Proceedings


Compliance with environmental laws and regulations is a matter of high priority for the Company.  Mueller'sMueller’s provision for environmental matters related to all properties was $0.9$1.7 million for 2016, $0.12019, $2.0 million for 2015,2018, and $1.2$7.5 million for 2014.2017.  The reserve for environmental matters was $21.9$20.9 million at December 31, 201628, 2019 and $21.7$23.6 million at December 26, 2015.29, 2018.  Environmental costsexpenses related to non-operating properties are classified as a componentpresented below operating income in the Consolidated Statements of other income, netIncome, and costs related to operating properties are included in cost of goods sold.  We do not currently anticipate that we will need to make material expenditures of approximately $2.1 million for compliance activities related to existing environmental matters during the next three fiscal years.



For a description of material pending environmental proceedings, see "Note 13Note 14 – Commitments and Contingencies"Contingencies in the Notes to Consolidated Financial Statements, which is incorporated herein by reference.


Other Business Factors


Our business is not materially dependent on patents, trademarks, licenses, franchises, or concessions held.  In addition, expenditures for Company-sponsored research and development activities were not material during 2016, 2015,2019, 2018, or 2014.2017.  No material portion of our business involves governmental contracts.  

Seasonality

Our net sales typically moderate in the fourth quarter as a result of the Company's sales is not significant.seasonal construction markets and customer shutdowns for holidays, year-end plant maintenance, and physical inventory counts. Also, our working capital typically increases in the first quarter in preparation for the construction season.


SEC Filings


We make available through our internet website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission (SEC).  To retrieve any of this information, you may access our internet home page at www.muellerindustries.com, select Investors, and then select SEC Filings.



ITEM 1A.RISK FACTORS


The Company is exposed to risk as it operates its businesses.  To provide a framework to understand our operating environment, we are providing a brief explanation of the more significant risks associated with our businesses.  Although we have tried to identify and discuss key risk factors, others could emerge in the future.  These risk factors should be considered carefully when evaluating the Company and its businesses.


Increases in costs and the availability of energy and raw materials used in our products could impact our cost of goods sold and our distribution expenses, which could have a material adverse impact on our operating margins.


6

Both the costs of raw materials used in our manufactured products (copper, brass, zinc, aluminum, and PVC and ABSplastic resins) and energy costs (electricity, natural gas and fuel) have been volatile during the last several years, which has resulted in changes in production and distribution costs.  For example, recent and pending climate change regulation and initiatives on the state, regional, federal, and international levels that have focused on reducing greenhouse gas (GHG) emissions from the energy and utility sectors may affect energy availability and costs in the near future.  While we typically attempt to pass costs through to our customers or to modify or adapt our activities to mitigate the impact of increases, we may not be able to do so successfully.  Failure to fully pass increases to our customers or to modify or adapt our activities to mitigate the impact could have a material adverse impact on our operating margins.  Additionally, if we are for any reason unable to obtain raw materials or energy, our ability to manufacture our products would be impacted, which could have a material adverse impact on our operating margins.


The unplanned departure of key personnel could disrupt our business.


We depend on the continued efforts of our senior management.  The unplanned loss of key personnel, or the inability to hire and retain qualified executives, could negatively impact our ability to manage our business.


Economic conditions in the housing and commercial construction industries, as well as changes in interest rates, could have a material adverse impact on our business, financial condition, and results of operations.


Our business is sensitive to changes in general economic conditions, particularly in the housing and commercial construction industries.  Prices for our products are affected by overall supply and demand in the market for our products and for our competitors'competitors’ products.  In particular, market prices of building products historically have been volatile and cyclical, and we may be unable to control the timing and extent of pricing changes for our products.  Prolonged periods of weak demand or excess supply in any of our businesses could negatively affect our revenues and margins and could result in a material adverse impact on our business, financial condition, and results of operations.



The markets that we serve, including, in particular, the housing and commercial construction industries, are significantly affected by movements in interest rates and the availability of credit.  Significantly higher interest rates could have a material adverse effect on our business, financial condition, and results of operations.  Our businesses are also affected by a variety of other factors beyond our control, including, but not limited to, employment levels, foreign currency exchange rates, unforeseen inflationary pressures, and consumer confidence.  Since we operate in a variety of geographic areas, our businesses are subject to the economic conditions in each such area.  General economic downturns or localized downturns in the regions where we have operations could have a material adverse effect on our business, financial condition, and results of operations.


The impact of economic conditions on the operations or liquidity of any party with which we conduct our business, including our suppliers and customers, may adversely impact our business.
 
Competitive conditions, including the impact of imports and substitute products and technologies, could have a material adverse effect on the demand for our products as well as our margins and profitability.


The markets we serve are competitive across all product lines.  Some consolidation of customers has occurred and may continue, which could shift buying power to customers.  In some cases, customers have moved production to low-cost countries such as China, or sourced components from there, which has reduced demand in North America for some of the products we manufacture.  These conditions could have a material adverse impact on our ability to maintain margins and profitability.  The potential threat of imports and substitute products is based upon many factors, including raw material prices, distribution costs, foreign exchange rates, production costs, and the development of emerging technologies and applications.  The end use of alternative import and/or substitute products could have a material adverse effect on our business, financial condition, and results of operations.  Likewise, the development of new technologies and applications could result in lower demand for our products and have a material adverse effect on our business.


Our exposure to exchange rate fluctuations on cross border transactions and the translation of local currency results into U.S. dollars could have an adverse impact on our results of operations or financial position.


7

We conduct our business through subsidiaries in several different countries and export our products to many countries.  Fluctuations in currency exchange rates could have a significant impact on the competitiveness of our products as well as the reported results of our operations, which are presented in U.S. dollars.  A portion of our products are manufactured in or acquired from suppliers located in lower cost regions.  Cross border transactions, both with external parties and intercompany relationships, result in increased exposure to foreign exchange fluctuations.  The strengthening of the U.S. dollar could expose our U.S. based businesses to competitive threats from lower cost producers in other countries such as China.  Lastly, our sales are translated into U.S. dollars for reporting purposes.  The strengthening of the U.S. dollar could result in unfavorable translation effects when the results of foreign operations are translated into U.S. dollars.  Accordingly, significant changes in exchange rates, particularly the British pound sterling, Mexican peso, Canadian dollar, and South Korean won, and Chinese renminbi, could have an adverse impact on our results of operations or financial position.


The vote by the United Kingdom (U.K.) to leave the European Union (EU) and implementation of Brexit could adversely affect us.
The June 2016
As of January 31, 2020, the U.K. referendum on its membership inis no longer a member of the EU resulted in a majority of U.K. voters voting to exit the EU ("Brexit")(Brexit).  As a result, we face risks associated withand uncertainty regarding the potential uncertaintyform and consequences that may followof the implementation of Brexit, including with respectthe possibility that the U.K. and the EU could fail to come to an agreement on the terms of the U.K. exit. The U.K. and the EU are currently in negotiations on the terms. Finalized terms are due on December 31, 2020. During this eleven month period, the U.K. will continue to follow all EU rules, and their trading relationship will remain the same. As a result of Brexit, we may be negatively impacted by increased volatility in exchange rates and interest rates and disruptions affecting our relationships with our existing and future customers, suppliers and employees.  Brexit and its implementation could also adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets.  Any of these effects of Brexit, and others we cannot anticipate, could adversely affect our business, results of operations and financial condition.


We are subject to claims, litigation, and regulatory proceedings that could have a material adverse effect on us.


We are, from time-to-time, involved in various claims, litigation matters, and regulatory proceedings.  These matters may include contract disputes, personal injury claims, environmental claims and administrative actions, Occupational Safety and Health Administration inspections or proceedings, other tort claims, employment and tax matters and other litigation including class actions that arise in the ordinary course of our business.  Although we intend to defend these matters vigorously, we cannot predict with certainty the outcome or effect of any claim or other litigation matter, and there can be no assurance as to the ultimate outcome


of any litigation or regulatory proceeding.  Litigation and regulatory proceedings may have a material adverse effect on us because of potential adverse outcomes, defense costs, the diversion of our management'smanagement’s resources, availability of insurance coverage and other factors.


A strike, other work stoppage or business interruption, or our inability to renew collective bargaining agreements on favorable terms, could impact our cost structure and our ability to operate our facilities and produce our products, which could have an adverse effect on our results of operations.


AsWe have a number of December 31, 2016, approximately 1,616 of our 4,244 employees werewho are covered by collective bargaining or similar agreements.  If we are unable to negotiate acceptable new agreements with the unions representing our employees upon expiration of existing contracts, we could experience strikes or other work stoppages.  Strikes or other work stoppages could cause a significant disruption of operations at our facilities, which could have an adverse impact on us.  New or renewal agreements with unions representing our employees could call for higher wages or benefits paid to union members, which would increase our operating costs and could adversely affect our profitability.  Higher costs and/or limitations on our ability to operate our facilities and manufacture our products resulting from increased labor costs, strikes or other work stoppages could have a material adverse effect on our results of operations.
   
In addition, unexpected interruptions in our operations or those of our customers or suppliers due to such causes as weather-related events or acts of God, such as earthquakes, could have an adverse effect on our results of operations.  For example, the Environmental Protection Agency has found that global climate change would be expected to increase the severity and possibly the frequency of severe weather patterns such as hurricanes.  Although the financial impact of such future events is not reasonably estimable at this time, should they occur, our operations in certain coastal and flood-prone areas or operations of our customers and suppliers could be adversely affected.


We are subject to environmental, health, and safety laws and regulations and future compliance may have a material adverse effect on our results of operations, financial position, or cash flows.


8

The nature of our operations exposes us to the risk of liabilities and claims with respect to environmental, health, and safety matters.  While we have established accruals intended to cover the cost of environmental remediation at contaminated sites, the actual cost is difficult to determine and may exceed our estimated reserves.  Further, changes to, or more rigorous enforcement or stringent interpretation of environmental or health and safety laws could require significant incremental costs to maintain compliance.  Recent and pending climate change regulation and initiatives on the state, regional, federal, and international levels may require certain of our facilities to reduce GHG emissions.  While not reasonably estimable at this time, this could require capital expenditures for environmental control facilities and/or the purchase of GHG emissions credits in the coming years.  In addition, with respect to environmental matters, future claims may be asserted against us for, among other things, past acts or omissions at locations operated by predecessor entities, or alleging damage or injury or seeking other relief in connection with environmental matters associated with our operations.  Future liabilities, claims, and compliance costs may have a material adverse effect on us because of potential adverse outcomes, defense costs, diversion of our resources, availability of insurance coverage, and other factors.  The overall impact of these requirements on our operations could increase our costs and diminish our ability to compete with products that are produced in countries without such rigorous standards; the long run impact could negatively impact our results and have a material adverse effect on our business.


If we do not successfully execute or effectively operate, integrate, leverage and grow acquired businesses, our financial results may suffer.


Our strategy for long-term growth, productivity and profitability depends in part on our ability to make prudent strategic acquisitions and to realize the benefits we expect when we make those acquisitions. In furtherance of this strategy, over the past several years, we have acquired businesses in Europe, Canada, South Korea, the Middle East, and the United States.
While we currently anticipate that our past and future acquisitions will enhance our value proposition to customers and improve our long-term profitability, there can be no assurance that we will realize our expectations within the time frame we have established, if at all, or that we can continue to support the value we allocate to these acquired businesses, including their goodwill or other intangible assets.

We may be subject to risks relating to our information technology systems.

We rely on information technology systems to process, transmit and store electronic information and manage and operate our business. The incidence of cyber attacks, computer hacking, computer viruses, worms, and other disruptive software, denial of service attacks, and other malicious cyber activities are on the rise worldwide. A breach of our information technology systems or those of our commercial partnerscould expose us, our customers, our suppliers, and our employees to risks of misuse or improper


disclosure of data, business information (including intellectual property) and other confidential information. We operate globally, and the legal rules governing data storage and transfers are often complex, unclear, and changing. A breach could also result in manipulation and destruction of data, production downtimes and operations disruptions. Any such breaches or events could expose us to legal liability and adversely affect our reputation, competitive position, business or results of operations.

TheTo the Stockholders and the Board of Directors and Stockholders of Mueller Industries, Inc.


Opinion on Internal Control over Financial Reporting

We have audited Mueller Industries, Inc.'s’s internal control over financial reporting as of December 31, 2016,28, 2019, based on criteria established in Internal Control—IntegratedControl-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework)framework) (the COSO criteria). In our opinion, Mueller Industries, Inc.'s (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 28, 2019, based onthe COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 28, 2019 and December 29, 2018, the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 28, 2019, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 26, 2020 expressed an unqualified opinion thereon.

Basis for Opinion

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


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

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


Definition and Limitations of Internal Control Over Financial Reporting

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


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


As indicated in the accompanying Management's Report on Internal Control over Financial Reporting, management's assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Jungwoo Metal Ind. Co., LTD, which is included in the 2016 consolidated financial statements of Mueller Industries, Inc. and constituted $49.7 million and $32.7 million of total and net assets, respectively, as of December 31, 2016, and $22.0 million and $0.2 million of net sales and operating income, respectively, for the year then ended.  Our audit of internal control over financial reporting of Mueller Industries, Inc. also did not include an evaluation of the internal control over financial reporting of Jungwoo Metal Ind. Co., LTD.

In our opinion, Mueller Industries, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Mueller Industries, Inc. as of December 31, 2016 and December 26, 2015, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2016 and our report dated March 1, 2017 expressed an unqualified opinion thereon.

FINANCIAL REVIEW


The Financial Review section of our Annual Report on Form 10-K consists of the following: Management'sManagement’s Discussion and Analysis of Results of Operations and Financial Condition (MD&A), the Consolidated Financial Statements, and Other Financial Information, all of which include information about our significant accounting policies, practices, and the transactions that impact our financial results.  The following MD&A describes the principal factors affecting the results of operations, liquidity and capital resources, contractual cash obligations, and the critical accounting estimates of the Company.  The discussion in the Financial Review section should be read in conjunction with the other sections of this Annual Report, particularly "ItemItem 1: Business"Business and our other detailed discussion of risk factors included in this MD&A.


OverviewOVERVIEW


We are a leading manufacturer of copper, brass, aluminum, and plastic products.  The range of these products we manufacture is broad:  copper tube and fittings; line sets; brass and copper alloy rod, bar, and shapes; aluminum and brass forgings; aluminum impact extrusions; PEX plastic fittingstube and valves;fittings; refrigeration valves and fittings; compressed gas valves; fabricated tubular products; pressure vessels; steel nipples; and steel nipples.insulated flexible duct systems.  We also resell imported brass and plastic plumbing valves, plastic fittings, malleable iron fittings, faucets and plumbing specialty products.  Mueller'sMueller’s operations are located throughout the United States and in Canada, Mexico, Great Britain, South Korea, the Middle East, and China.


During the first quarter of 2016, we made changes to our management reporting structure as a result of a change in the way the Chief Executive Officer, who serves as the Chief Operating Decision Maker, manages and evaluates the business, makes key operating decisions, and allocates resources.  Previously, we had two reportable segments: Plumbing & Refrigeration and OEM.  During the first quarter, we realigned our operating segments into three reportable segments: Piping Systems, Industrial Metals, and Climate.  The changes to the reporting structure resulted from management's decision to operationally separate certain businesses in order to enhance the level of focus on those businesses.  This included the appointment of separate management teams.  In addition, as a result of several acquisitions, we separated certain businesses with similar characteristics to create the Climate and Industrial Metals segments.  These businesses were previously aggregated within the OEM segment.  Management has recast certain prior year amounts to conform to the current year presentation. Each of the reportable segments is composed of certain operating segments that are aggregated primarily by the nature of products offered as follows:


·
Piping Systems:  The Piping Systems segment is composed of Domestic Piping Systems Group, Canadian Operations,Piping Systems:  The Piping Systems segment is composed of Domestic Piping Systems Group, Great Lakes Copper, Heatlink Group, Die-Mold, European Operations, Trading Group, Mueller-Xingrong (our Chinese joint venture), and Jungwoo-Mueller (our South Korean joint venture).  The Domestic Piping Systems Group manufactures copper tube, fittings, and line sets.  These products are manufactured in the U.S., sold in the U.S., and exported to markets worldwide. Great Lakes Copper manufactures copper tube and line sets in Canada and sells the products primarily in the U.S. and Canada.  Heatlink Group manufactures a complete line of products for PEX plumbing and radiant systems in Canada and sells these products in Canada and the U.S. Die-Mold manufactures PEX and other plumbing-related fittings and plastic injection tooling in Canada and sells these products in Canada and the U.S. European Operations manufacture copper tube in the United Kingdom, which is sold throughout Europe.  The Trading Group manufactures pipe nipples and sources products for import distribution in North America.  Jungwoo-Mueller manufactures copper-based joining products that are sold worldwide.  The Piping Systems segment sells products to wholesalers in the plumbing and refrigeration markets, distributors to the manufactured housing and recreational vehicle industries, building material retailers, and air-conditioning original equipment manufacturers (OEMs).  The Domestic Piping Systems Group manufactures copper tube and fittings,  plastic fittings, and line sets.  These products are manufactured in the U.S., sold in the U.S., and exported to markets worldwide.    The Canadian Operations manufacture copper tube and line sets in Canada and sell the products primarily in the U.S. and Canada. European Operations manufacture copper tube in the United Kingdom, which is sold throughout Europe.  The Trading Group manufactures pipe nipples and sources products for import distribution in North America.  Mueller-Xingrong manufactures engineered copper tube primarily for air-conditioning applications; these products are sold primarily to OEMs located in China.  Jungwoo-Mueller manufactures copper-based joining products that are sold worldwide.  The Piping Systems segment sells products to wholesalers in the plumbing and refrigeration markets, distributors to the manufactured housing and recreational vehicle industries, building material retailers, and air-conditioning OEMs.

TABLE OF CONTENTS
INDEX

New housing starts and commercial construction are important determinants of the Company'sour sales to the heating, ventilation, and air-conditioning, refrigeration, and plumbing markets because the principal end use of a significant portion of our products is in the construction of single and multi-family housing and commercial buildings.  Repairs and remodeling projects are also important drivers of underlying demand for these products.  In addition, our products are used in various transportation, automotive, and industrial applications.


Residential construction activity has shown improvement in recent years, but remains at levels below long-term historical averages.  Continued improvement is expected, but may be tempered by continuing low labor participation rates, the pace of household formations, and tighter lending standards.  Per the U.S. Census Bureau, actual housing starts in the U.S. were 1.21.29 million in 2016,2019, which compares to 1.11.25 million in 2015 2018


and 1.01.20 million in 2014.2017.  Mortgage rates remain at historically low levels, as the average 30-year fixed mortgage rate was approximately 3.653.94 percent in 20162019 and 3.854.54 percent in 2015.  

2018.  The private nonresidential construction sector, which includes offices, industrial, health care, and retail projects, has also shown improvement in recent years.  Per the U.S. Census Bureau, the value of private nonresidential construction put in place was $420.1$450.5 billion in 2016, $389.92019, $450.9 billion in 2015,2018, and $359.7$444.0 billion in 2014.  We expect that most of these conditions will continue to improve.2017. 


Profitability of certain of our product lines depends upon the "spreads"“spreads” between the cost of raw material and the selling prices of our products.  The open market prices for copper cathode and copper and brass scrap, for example, influence the selling price of copper tube aand brass rod, two principal productproducts manufactured by the Company.  We attempt to minimize the effects on profitability from fluctuations in material costs by passing through these costs to our customers.  Our earnings and cash flow are dependent upon these spreads that fluctuate based upon market conditions.


Earnings and profitability are also impacted by unit volumes that are subject to market trends, such as substitute products, imports, technologies, and market share.  In our core product lines, we intensively manage our pricing structure while attempting to maximize profitability.  From time-to-time, this practice results in lost sales opportunities and lower volume.  For plumbing systems, plastics are the primary substitute product; these products represent an increasing share of consumption.  U.S. consumption of copper tube is still predominantly supplied by U.S. manufacturers.  For certain air-conditioning and refrigeration applications, aluminum based systems are the primary substitution threat.  We cannot predict the acceptance or the rate of switching that may occur.  U.S. consumption of copper tube and brass rod is still predominantly supplied by U.S. manufacturers.  In the last decade,recent years, brass rod consumption in the U.S. has declined due to the outsourcing of many manufactured products from offshore regions.

The decrease in net sales in 20162019 was primarily due to (i) lower unit sales volume of $110.3 million in our core product lines, primarily brass rod and copper tube, and (ii) lower net selling prices of $189.0$91.7 million in our core product lines. These decreases were partially offset by (i) incremental sales of $100.1 million recorded by ATCO, acquired in July 2018, (ii) an increase in sales in our non-core product lines of $22.4 million, and (iii) incremental sales of $4.0 million recorded by Die-Mold, acquired in March 2018.

The increase in net sales in 2018 was primarily due to (i) higher unit sales volume of $126.2 million in our domestic core product lines, primarily copper tube and brass rod, (ii) higher net selling prices of $99.8 million in our core product lines, (iii) sales of $90.0 million recorded by ATCO, acquired in July 2018, (iv) an increase in sales in our non-core product lines of $21.2 million,


(v) incremental sales of $9.6 million of recorded by Heatlink Group, acquired in May 2017, and (vi) sales of $6.8 million recorded by Die-Mold, acquired in March 2018. These increases were partially offset by (i) the absence of sales of $67.3 million recorded by Mueller-Xingrong, a business we sold during June 2017, and (ii) lower unit sales volume of $33.0$44.5 million in our non-domestic core product lines.  The decrease in net sales resulting from lower net selling prices also reflects the impact of translating net sales of the Company's foreign operations to U.S. dollars, which was approximately $43.6 million.  These decreases were partially offset by (i) $139.4 million of incremental sales recorded by Great Lakes Copper Ltd. (Great Lakes), acquired in July 2015, (ii) $22.0 million of sales recorded by Jungwoo-Mueller, acquired in April 2016, (iii) $19.2 million of incremental sales recorded by Sherwood Valve LLC (Sherwood), acquired in June 2015, and (iv) $3.5 million of incremental sales recorded by Turbotec Products, Inc. (Turbotec), acquired in March 2015.

The decrease in net sales in 2015 was primarily due to (i) lower net selling prices of $218.3 million in our core product lines, primarily copper tube and brass rod, (ii) lower unit sales volume of $79.9 million in our core product lines, primarily in the Industrial Metals segment, and (iii) the absence of sales of $57.5 million recorded by Primaflow, a business we sold during November 2014.  These decreases were offset by (i) $90.5 million of sales recorded by Great Lakes, (ii) $20.8 million of sales recorded by Sherwood, and (iii) $16.8 million of sales recorded by Turbotec, all of which were businesses acquired during 2015.


Net selling prices generally fluctuate with changes in raw material costs.  Changes in raw material costs are generally passed through to customers by adjustments to selling prices.  The following graph shows the Comex average copper price per pound by quarter for the most recent three-year period:

Liquidity and Outlook


Management believesWe believe that cash provided by operations, funds available under the credit agreement,Credit Agreement, and cash and cash equivalents on hand will be adequate to meet our liquidity needs, including working capital, capital expenditures, and debt payment obligations.  Our current ratio was 4.13.0 to 1 as of December 31, 2016.28, 2019.

The Company occasionally enters into forward fixed-price arrangements with certain customers.  We may utilize futures contracts to hedge risks associated with these forward fixed-price arrangements.  We may also utilize futures contracts to manage price risk associated with inventory.  Depending on the nature of the hedge, changes in the fair value of the futures contracts will either be offset against the change in fair value of the inventory through earnings or recognized as a component of accumulated other comprehensive income (AOCI) in equity and reflected in earnings upon the sale of inventory.  Periodic value fluctuations of the contracts generally offset the value fluctuations of the underlying fixed-price transactions or inventory.  At December 31, 2016,28, 2019, we held open futures contracts to purchase approximately $10.2$21.3 million of copper over the next 12 months related to fixed-price sales orders and to sell approximately $28.7$1.9 million of copper over the next threeseven months related to copper inventory.

We may enter into futures contracts or forward fixed-price arrangements with certain vendors to manage price risk associated with natural gas purchases.  The effective portion of gains and losses with respect to positions are deferred in equity as a component of AOCI and reflected in earnings upon consumption of natural gas.  Periodic value fluctuations of the futures contracts generally offset the value fluctuations of the underlying natural gas prices.  There were no open futures contracts to purchase natural gas at December 31, 2016.28, 2019.



Interest Rates


The Company had variable-rate debt outstanding of $212.2$97.0 million at December 31, 201628, 2019 and $216.0$202.6 million at December 26, 2015.29, 2018.  At thesethis borrowing levels,level, a hypothetical 10 percent increase in interest rates would have had an insignificant unfavorable impact on our pre-tax earnings and cash flows.  The primary interest rate exposuresexposure on floating-ratevariable-rate debt areis based on LIBOR and the base-lending rate published by the People's Bank of China.  There was $15.2 million of fixed-rate debt outstanding as of December 31, 2016, and no fixed-rate debt outstanding as of December 26, 2015.LIBOR.

Included in the variable-rate debt outstanding is the Company's $200.0 million Credit Agreement which bears interest based on LIBOR.  We have reduced our exposure to increases in LIBOR by entering into interest rate swap contracts.  The fair value of these contracts has been recorded in the Consolidated Balance Sheets, and a portion of the related gains and losses on the contracts are deferred in stockholders' equity as a component of AOCI.  Deferred gains or losses on the contracts will be recognized in interest expense in the period in which the related interest payment being hedged is expensed.  The interest rate swap agreement had an effective date of January 12, 2015.


Foreign Currency Exchange Rates


Foreign currency exposures arising from transactions include firm commitments and anticipated transactions denominated in a currency other than an entity'sentity’s functional currency.  The Company and its subsidiaries generally enter into transactions denominated in their respective functional currencies.  We may utilize certain futures or forward contracts with financial institutions to hedge foreign currency transactional exposures.  Gains and losses with respect to these positions are deferred in equity as a component of AOCI and reflected in earnings upon collection of receivables or payment of commitments.  At December 31, 2016,28, 2019, we had open forward contracts with a financial institution to sell approximately 3.20.1 million euros, 15.621.7 million Swedish kronor, 7.6and 8.1 million Norwegian kroner and 1.2 million U.S. dollars through April 2017.2020.


The Company'sCompany’s primary foreign currency exposure arises from foreign-denominated revenues and profits and their translation into U.S. dollars.  The primary currencies to which we are exposed include the Canadian dollar, the British pound sterling, the Mexican peso, and the South Korean won, and the Chinese renminbi.won.  The Company generally views its investments in foreign subsidiaries with a functional currency other than the U.S. dollar as long-term.  As a result, we generally do not hedge these net investments.  The net investment in foreign subsidiaries translated into U.S. dollars using the year-end exchange rates was $271.6$397.1 million at December 31, 201628, 2019 and $249.5$376.6 million at December 26, 2015.29, 2018.  The potential loss in value of the Company'sCompany’s net investment in foreign subsidiaries resulting from a hypothetical 10 percent adverse change in quoted foreign currency exchange rates at December 31, 201628, 2019 and December 26, 201529, 2018 amounted to $27.2$39.7 million and $25.0$37.7 million, respectively.  This change would be reflected in the foreign currency translation component of AOCI in the equity section of our Consolidated Balance Sheets until the foreign subsidiaries are sold or otherwise disposed.


We have significant investments in foreign operations whose functional currency is the British pound sterling, the Mexican peso, the Canadian dollar, the Chinese renminbi, and the South Korean won.  During 2016,2019, the value of the British pound decreasedincreased approximately 17three percent, the Mexican peso decreasedincreased approximately 164 percent, the Canadian dollar increased approximately three percent, the Chinese renminbi decreased approximately sevenfour percent, and the South Korean won remained consistent,decreased approximately four percent, relative to the U.S. dollar.  The resulting net foreign currency translation lossesgains were included in calculating net other comprehensive loss for the year ended December 28, 2019 and were recorded as a component of AOCI.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

TABLE OF CONTENTS
INDEX
Critical Accounting Policies and Estimates

The Company'sCompany’s accounting policies are more fully described in "NoteNote 1 - Summary of Significant Accounting Policies"Policies in the Notes to Consolidated Financial Statements.  As disclosed in Note 1, the preparation of financial statements in conformity with general accepted accounting principles in the United States requires management to make estimates and assumptions about future events that affect amounts reported in the financial statements and accompanying notes. Actual results could differ significantly from those estimates.  Management believes the following discussion addresses our most critical accounting policies, which are those that are most important to the portrayal of the Company'sCompany’s financial condition and results of operations and require management'smanagement’s most difficult, subjective, and complex judgments.


Inventory Valuation Reserves


Our inventories are valued at the lower-of-cost-or-market.  The market price of copper cathode and scrap are subject to volatility.  During periods when open market prices decline below net realizable value, the Company may need to provide an allowance to reduce the carrying value of its inventory.  In addition, certain items in inventory may be considered excess or obsolete and, as such, we may establish an allowance to reduce the carrying value of those items to their net realizable value.  Changes in these estimates related to the value of inventory, if any, may result in a materially adverse impact on our reported financial position or results of operations.  The Company recognizes the impact of any changes in estimates, assumptions, and judgments in income in the period in which they are determined.
 
As of December 31, 201628, 2019 and December 26, 2015,29, 2018, our inventory valuation reserves were $6.9$6.3 million and $6.2$7.0 million, respectively.  The expense recognized in each of these periods was immaterial to our Consolidated Financial Statements.



Impairment of Goodwill


As of December 31, 2016,28, 2019, we had $124.0$153.3 million of recorded goodwill from our business acquisitions, representing the excess of the purchase price over the fair value of the net assets we have acquired.  During 20162019 we recorded $0.4$1.5 million in additional goodwill associated with our Jungwoo-Mueller acquisitionATCO and $4.1 millionDie-Mold acquisitions in additional goodwill associatedconjunction with a deferred tax liability resulting from a basis difference in the long-lived assets acquired from Great Lakes.finalization of the purchase price allocations.
Goodwill is subject to impairment testing, which is performed annually as of the first day of the fourth quarter unless circumstances indicate the need to accelerate the timing of the tests.  These circumstances include a significant change in the business climate, operating performance indicators, competition, or sale or disposition of a significant portion of one of our businesses.  In our evaluation of goodwill impairment, we perform a qualitative assessment at the reporting unit level that requires management judgment and the use of estimates to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount.  If the qualitative assessment is not conclusive, we proceed to a two-step process to test goodwill for impairment.  The first step is to comparemanagement compares the fair value of a reporting unit with its carrying amount and will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit to its carrying value (including attributable goodwill).  If this process indicates that theunit’s fair value, is less thannot to exceed the carrying value, a second step of impairment testing is performed to measure the potentialtotal amount of goodwill impairment loss.  In step two, we allocate the fair value ofallocated to the reporting unit determined in step one to its assets and liabilities as if it had just been acquired in a business combination and the purchase price was equivalent to the fair value of the reporting unit.  The excess of the fair value of the reporting unit over the amount assigned to its assets and liabilities is referred to as the implied fair value of goodwill.  The implied fair value of goodwill is then compared to the actual carrying value of goodwill.  If the implied fair value is less than the carrying value, we would be required to recognize an impairment loss for that excess.
We identify reporting units by evaluating components of our operating segments and combining those components with similar economic characteristics.  Reporting units with significant recorded goodwill include Domestic Piping Systems, Canadian Operations,B&K LLC, Great Lakes, Heatlink Group, Die-Mold, European Operations, Jungwoo-Mueller, Westermeyer, Turbotec, and Turbotec.ATCO.
The fair value of each reporting unit is estimated using a combination of the income and market approaches, incorporating market participant considerations and management'smanagement’s assumptions on revenue growth rates, operating margins, discount rates and expected capital expenditures. Estimates used by management can significantly affect the outcome of the impairment test.  Changes in forecasted operating results and other assumptions could materially affect these estimates.

TABLE OF CONTENTS
INDEX
We evaluated each reporting unit during the fourth quarters of 20162019 and 2015,2018, as applicable. The estimated fair value of each of these reporting units exceeded its carrying values in 20162019 and 2015,2018, and we do not believe that any of these reporting units were at risk of impairment as of December 31, 2016.28, 2019.


Pension and Other Postretirement Benefit Plans

We sponsor several qualified and nonqualified pension and other postretirement benefit plans in the U.S. and certain foreign locations.  We recognize the overfunded or underfunded status of the plans as an asset or liability in the Consolidated Balance Sheets with changes in the funded status recorded through comprehensive income in the year in which those changes occur.  The obligations for these plans are actuarially determined and affected by assumptions, including discount rates, expected long-term return on plan assets for defined benefit pension plans, and certain employee-related factors, such as retirement age and mortality.  We evaluate the assumptions periodically and makes adjustments as necessary.

The expected return on plan assets is determined using the market value of plan assets.  Differences between assumed and actual returns are amortized to the market value of assets on a straight-line basis over the average remaining service period of the plan participants using the corridor approach.  The corridor approach defers all actuarial gains and losses resulting from variances between actual results and actuarial assumptions.  These unrecognized gains and losses are amortized when the net gains and losses exceed 10 percent of the greater of the market value of the plan assets or the projected benefit obligation.  The amount in excess of the corridor is amortized over the average remaining service period of the plan participants.  For 2019, the average remaining service period for the pension plans was nine years.

Environmental Reserves


We recognize an environmental reserve when it is probable that a loss is likely to occur and the amount of the loss is reasonably estimable.  We estimate the duration and extent of our remediation obligations based upon reports of outside consultants;consultants, internal and third party estimates and analyses of cleanup costs;costs and ongoing monitoring costs, communications with regulatory agencies;agencies, and changes in environmental law.  If we were to determine that our estimates of the duration or extent of our environmental obligations were no longer accurate, we would adjust our environmental reserve accordingly in the period that such determination is made.  Estimated future expenditures for environmental remediation are not discounted to their present value.  Accrued environmental liabilities are not reduced by potential insurance reimbursements.


Environmental expenses that relate to ongoing operations are included as a component of cost of goods sold.  Environmental expenses related to non-operating properties are included in otherpresented below operating income net in the Consolidated Statements of Income.



Income Taxes


We estimate total income tax expense based on domestic and international statutory income tax rates in the tax jurisdictions where we operate, permanent differences between financial reporting and tax reporting, and available credits and incentives.


Deferred income tax assets and liabilities are recognized for the future tax effects of temporary differences between the treatment of certain items for financial statement and tax purposes using tax rates in effect for the years in which the differences are expected to reverse.  Realization of certain components of deferred tax assets is dependent upon the occurrence of future events.  


Valuation allowances are recorded when, in the opinion of management, it is more likely than not that all or a portion of the deferred tax assets will not be realized.  These valuation allowances can be impacted by changes in tax laws, changes to statutory tax rates, and future taxable income levels, and are based on our judgment, estimates, and assumptions.  In the event we were to determine that we would not be able to realize all or a portion of the net deferred tax assets in the future, we would increase the valuation allowance through a charge to income tax expense in the period that such determination is made.  Conversely, if we were to determine that we would be able to realize our deferred tax assets in the future, in excess of the net carrying amounts, we would decrease the recorded valuation allowance through a decrease to income tax expense in the period that such determination is made.


We record liabilities for known or anticipated tax issues based on our analysis of whether, and the extent to which, additional taxes will be due.  These unrecognized tax benefits are retained until the associated uncertainty is resolved.  Tax benefits for uncertain tax positions that are recognized in the Consolidated Financial Statements are measured as the largest amount of benefit, determined on a cumulative probability basis, that is more likely than not to be realized upon ultimate settlement.  To the extent we prevail in matters for which a liability for an uncertain tax position is established or are required to pay amounts in excess of the liability, our effective tax rate in a given period may be materially affected.

Revenue Recognition

Given the nature of the Company’s business and product offerings, sales transactions with customers are generally comprised of a two-for-one stock splitsingle performance obligation that involves delivery of its common stock effectedthe products identified in the formcontracts with customers.  Performance obligations are generally satisfied at the point in time of a stock dividend of one share for each outstanding share.  The record date for the stock split was March 14, 2014,shipment and the additional shares were distributed on March 28, 2014.  Accordingly, all references to share and per share amounts presented in the Consolidated Financial Statements and this Annual Report on Form 10-K have been adjusted retroactively to reflect the stock split.

Revenue Recognition

Revenuepayment is recognized when title and risk of loss pass to the customer, provided collectiongenerally due within sixty days. Variable consideration is determined to be probable and no significant obligations remain for the Company.  Estimatesestimated for future rebates on certain product lines and product returns are recognizedreturns.

Acquisitions


Accounting for acquisitions requires the Company to recognize separately from goodwill the assets acquired and liabilities assumed at their acquisition date fair values.  Goodwill is measured as the excess of the purchase price over the net amount allocated to the identifiable assets acquired and liabilities assumed.  While management uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, the estimates are inherently uncertain and subject to refinement.  As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill.  The operating results generated by the acquired businesses are included in the Consolidated Statements of Income from their respective dates of acquisition.  Acquisition related costs are expensed as incurred.  See "NoteNote 2 – Acquisitions and Dispositions"Dispositions for additional information.

The Company provides an allowance for receivables that may not be fully collected.  In circumstances where the Company is aware of a customer'scustomer’s inability to meet their financial obligations (e.g., bankruptcy filings or substantial credit rating downgrades), it records an allowance for doubtful accounts against amounts due to reduce the net recognized receivable to the amount it believes most likely will be collected.  For all other customers, the Company recognizes an allowance for doubtful accounts based on its historical collection experience.  If circumstances change (e.g., greater than expected defaults or an unexpected material change in a major customer'scustomer’s ability to meet their financial obligations), the Company could change its estimate of the recoverability of amounts due by a material amount.


Inventories


The Company'sCompany’s inventories are valued at the lower-of-cost-or-market.  The material component of its U.S. copper tube and copper fittings inventories is valued on a LIFO basis.  Other manufactured inventories, includingbasis and the non-material components of U.S. copper tube and copper fittings inventories are valued on a FIFO basis.  The material component of its U.K. and Canadian copper tube inventories are valued on a FIFO basis. The material component of its brass rod and forgings inventories are valued on a FIFO basis. Certain inventories purchased for resale are valued on an average cost basis.  Elements of cost in finished goods inventory in addition to the cost of material include depreciation, amortization, utilities, maintenance, production wages, and transportation costs.
 
The market price of copper cathode and scrap is subject to volatility.  During periods when open market prices decline below net book value, the Company may need to provide an allowance to reduce the carrying value of its inventory.  In addition, certain items in inventory may be considered obsolete and, as such, the Company may establish an allowance to reduce the carrying value of those items to their net realizable value.  Changes in these estimates related to the value of inventory, if any, may result in a materially adverse impact on the Company'sCompany’s reported financial position or results of operations.  The Company recognizes the impact of any changes in estimates, assumptions, and judgments in income in the period in which it is determined.  See "Note 4Note 5Inventories"Inventories for additional information.


Leases

The Company leases certain manufacturing facilities, distribution centers, office space, and equipment. Leases with an initial term of twelve months or less are not recorded on the balance sheet; expense for these leases is recognized on a straight line-basis over the term of the lease. Most of the Company’s leases include one or more options to renew up to five years and have remaining terms of one to fifteen years. These options are not included in the Company’s valuation of the right-of-use assets as the Company is not reasonably certain to exercise the options.

The Company has certain vehicle leases that are financing; however, these leases are deemed immaterial for disclosure. See “Note 8 – Leases” for additional information.

Property, Plant, and Equipment


Property, plant, and equipment is stated at cost less accumulated depreciation.  Expenditures for major additions and improvements are capitalized, while minor replacements, maintenance, and repairs are charged to expense as incurred.  Depreciation of buildings, machinery, and equipment is provided on the straight-line method over the estimated useful lives ranging from 20 to 40 years for buildings and five to 20 years for machinery and equipment.  Leasehold improvements are amortized over the lesser of their useful life or the remaining lease term.  


The Company continually evaluates these assets to determine whether events or changes in circumstances have occurred that may warrant revision of the estimated useful life or whether the remaining balance should be evaluated for possible impairment.  See "Note 7Note 9 – Property, Plant, and Equipment, Net"Net for additional information.



Goodwill


Goodwillis recognized for the excess of the purchase price over the fair value of tangible and identifiable intangible net assets of businesses acquired. Several factors give rise to goodwill in business acquisitions, such as the expected benefit from synergies of the combination and the existing workforce of the acquired business. Goodwill is evaluated annually for possible impairment as of the first day of the fourth quarter unless circumstances indicate the need to accelerate the timing of the evaluation. In the evaluation of goodwill impairment, management performs a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment is not conclusive, management proceeds to a two-step process to test goodwill for impairment, including comparingcompares the fair value of a reporting unit with its carrying amount and will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit to its carrying value (including attributable goodwill).  If this process indicates that theunit’s fair value, is less thannot to exceed the carrying value, a second step of impairment testing is performed to measure the potentialtotal amount of goodwill impairment loss.allocated to the reporting unit.

TABLE OF CONTENTS
INDEX
Fair value for the Company'sCompany’s reporting units is determined using a combination of the income and market approaches (level 3 within the fair value hierarchy), incorporating market participant considerations and management'smanagement’s assumptions on revenue growth rates, operating margins, discount rates and expected capital expenditures.  The market approach measures the fair value of a business through the analysis of publicly traded companies or recent sales of similar businesses.  The income approach uses a discounted cash flow model to estimate the fair value of reporting units based on expected cash flows (adjusted for capital investment required to support operations) and a terminal value.  This cash flow stream is discounted to its present value to arrive at a fair value for each reporting unit.  Future earnings are estimated using the Company'sCompany’s most recent annual projections, applying a growth rate to future periods.  Those projections are directly impacted by the condition of the markets in which the Company'sCompany’s businesses participate.  The discount rate selected for the reporting units is generally based on rates of return available for comparable companies at the date of valuation.  Fair value determinations may include both internal and third-party valuations.  See "Note 8Note 10 – Goodwill and Other Intangible Assets"Assets for additional information.


InvestmentInvestments in Unconsolidated Affiliates


The Company owns a 50 percent interest in Tecumseh Products Holding LLC (Joint Venture), an unconsolidated affiliate that acquired Tecumseh Products Company (Tecumseh).  The Company also owns a 50 percent interest in a second unconsolidated affiliate that providedprovides financing to Tecumseh in conjunction with the acquisition.Tecumseh.  These investments are recorded using the equity method of accounting, as the Company can exercise significant influence but does not own a majority equity interest or otherwise control the respective entities.  Under the equity method of accounting, these investments are stated at initial cost and are adjusted for subsequent additional investments and the Company'sCompany’s proportionate share of earnings or losses and distributions.


The Company records itsproportionate share of the investee'sinvestees’ net income or loss, net of foreign taxes, one quarter in arrears as income (loss) from unconsolidated affiliates, net of foreign tax, in the Consolidated Statements of Income.  The Company'sCompany’s proportionate share of the investees'investees’ other comprehensive income (loss), net of income taxes, is recorded in the Consolidated Statements of Comprehensive Income and Consolidated Statements of Changes in Equity.  The U.S. tax effect of the Company’s proportionate share of Tecumseh’s income or loss is recorded in income tax expense in the Consolidated Statements of Income. In general, the equity investment in the unconsolidated affiliates is equal to the current equity investment plus that entity's undistributed earnings.the investees’ net accumulated losses.


The investmentCompany also owns a 40 percent interest in Mueller Middle East BSC.

The investments in unconsolidated affiliates isare assessed periodically for impairment and is written down when the carrying amount is not considered fully recoverable.  See "Note 9Note 11InvestmentInvestments in Unconsolidated Affiliates"Affiliates for additional information.


Self-Insurance Accruals


The Company is primarily self-insured for workers'workers’ compensation claims and benefits paid under certain employee health care programs.  Accruals are primarily based on estimated undiscounted cost of claims, which includes incurred but not reported claims, and are classified as accrued wages and other employee costs.


Pension and Other Postretirement Benefit Plans


The Company sponsors several qualified and nonqualified pension and other postretirement benefit plans in the U.S. and certain foreign locations.  The Company recognizes the overfunded or underfunded status of the plans as an asset or liability in the Consolidated Balance SheetSheets with changes in the funded status recorded through comprehensive income in the year in which those changes occur.  The obligations for these plans are actuarially determined and affected by assumptions, including discount rates,


expected long-term return on plan assets for defined benefit pension plans, and certain employee-related factors, such as retirement age and mortality.  The Company evaluates its assumptions periodically and makes adjustments as necessary.


F-26

TABLE OF CONTENTS
INDEX
The expected return on plan assets is determined using the market value of plan assets.  Differences between assumed and actual returns are amortized to the market value of assets on a straight-line basis over the average remaining service period of the plan participants using the corridor approach.  The corridor approach defers all actuarial gains and losses resulting from variances between actual results and actuarial assumptions.  These unrecognized gains and losses are amortized when the net gains and losses exceed 10 percent of the greater of the market value of the plan assets or the projected benefit obligation.  The amount in excess of the corridor is amortized over the average remaining service period of the plan participants.  For 2016,2019, the average remaining service period for the pension plans was nine years.  See "Note 12 –Benefit Plans"Note 13 – Benefit Plans for additional information.


Environmental Reserves and Environmental Expenses


The Company recognizes an environmental liability when it is probable the liability exists and the amount is reasonably estimable.  The Company estimates the duration and extent of its remediation obligations based upon reports of outside consultants;consultants, internal and third party estimates and analyses of cleanup costs and ongoing monitoring costs;costs, communications with regulatory agencies;agencies, and changes in environmental law.  If the Company were to determine that its estimates of the duration or extent of its environmental obligations were no longer accurate, it would adjust environmental liabilities accordingly in the period that such determination is made.  Estimated future expenditures for environmental remediation are not discounted to their present value.  Accrued environmental liabilities are not reduced by potential insurance reimbursements.


Environmental expenses that relate to ongoing operations are included as a component of cost of goods sold.  Environmental expenses related to non-operating properties are includedpresented below operating income in other income, net on the Consolidated Statements of Income.  See "Note 13Note 14 – Commitments and Contingencies"Contingencies for additional information.


Earnings Per Share


Basic earnings per share is computed based on the weighted average number of common shares outstanding.  Diluted earnings per share reflects the increase in weighted average common shares outstanding that would result from the assumed exercise of outstanding stock options and vesting of restricted stock awards calculated using the treasury stock method.  Approximately 190 thousand and 427 thousand stock-basedThere were 0 awards were excluded from the computation of diluted earnings per share for the yearsyear ended December 31, 201628, 2019, and approximately 54 thousand stock-based awards excluded from the computation of diluted earnings per share for the year ended December 26, 2015, respectively,29, 2018, because they were antidilutive.


Income Taxes


Deferred income tax assets and liabilities are recognized when differences arise between the treatment of certain items for financial statement and tax purposes.  Realization of certain components of deferred tax assets is dependent upon the occurrence of future events.  The Company records valuation allowances to reduce its deferred tax assets to the amount it believes is more likely than not to be realized.  These valuation allowances can be impacted by changes in tax laws, changes to statutory tax rates, and future taxable income levels and are based on the Company'sCompany’s judgment, estimates, and assumptions regarding those future events.  In the event the Company was to determine that it would not be able to realize all or a portion of the net deferred tax assets in the future, it would increase the valuation allowance through a charge to income tax expense in the period that such determination is made.  Conversely, if it werewas to determine that it would be able to realize its deferred tax assets in the future, in excess of the net carrying amounts, the Company would decrease the recorded valuation allowance through a decrease to income tax expense in the period that such determination is made.


The Company provides for uncertain tax positions and the related interest and penalties, if any, based upon management'smanagement’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities.  Tax benefits for uncertain tax positions that are recognized in the financial statements are measured as the largest amount of benefit, determined on a cumulative probability basis, that is more likely than not to be realized upon ultimate settlement.  To the extent the Company prevails in matters for which a liability for an uncertain tax position is established or is required to pay amounts in excess of the liability, the Company'sCompany’s effective tax rate in a given financial statement period may be affected.


These estimates are highly subjective and could be affected by changes in business conditions and other factors.  Changes in any of these factors could have a material impact on future income tax expense.  See "Note 14Note 15 – Income Taxes"Taxes for additional information.

Taxes Collected from Customers and Remitted to Governmental Authorities


Taxes assessed by a governmental authority that are directly imposed on a revenue producing transaction between the Company and its customers, primarily value added taxes in foreign jurisdictions, are accounted for on a net (excluded from revenues and costs) basis.


Stock-Based Compensation


The Company has in effect stock incentive plans under which stock-based awards have been granted to certain employees and members of its Board of Directors.  Stock-based compensation expense is recognized in the Consolidated Statements of Income as a component of selling, general, and administrative expense based on the grant date fair value of the awards.  See "Note 16Note 17 – Stock-Based Compensation"Compensation for additional information.


Concentrations of Credit and Market Risk


Concentrations of credit risk with respect to accounts receivable are limited due to the large number of customers comprising the Company'sCompany’s customer base, and their dispersion across different geographic areas and different industries, including HVAC, plumbing, refrigeration, hardware, automotive, OEMs, and others.


The Company minimizes its exposure to base metal price fluctuations through various strategies.  Generally, it prices an equivalent amount of copper raw material, under flexible pricing arrangements it maintains with its suppliers, at the time it determines the selling price of finished products to its customers.


Derivative Instruments and Hedging Activities


The Company'sCompany’s earnings and cash flows are subject to fluctuations due to changes in commodity prices, foreign currency exchange rates, and interest rates.  The Company uses derivative instruments such as commodity futures contracts, foreign currency forward contracts, and interest rate swaps to manage these exposures.


All derivatives are recognized in the Consolidated Balance Sheets at their fair value.  On the date the derivative contract is entered into, it is either a) designated as a hedge of  (i) a forecasted transaction or the variability of cash flow to be paid (cash flow hedge) or (ii) the fair value of a recognized asset or liability (fair value hedge), or b) not designated in a hedge accounting relationship, even though the derivative contract was executed to mitigate an economic exposure (economic hedge), as the Company does not enter into derivative contracts for trading purposes (economic hedge).purposes.  Changes in the fair value of a derivative that is qualified, designated, and highly effective as a cash flow hedge are recorded in stockholders'stockholders’ equity within accumulated other comprehensive income (AOCI), to the extent effective, until they are reclassified to earnings in the same period or periods during which the hedged transaction affects earnings.  Changes in the fair value of a derivative that is qualified, designated, and highly effective as a fair value hedge, along with the gain or loss on the hedged recognized asset or liability that is attributable to the hedged risk, are recorded in current earnings.  Changes in the fair value of undesignated derivative instruments executed as economic hedges and the ineffective portion of designated derivative instrumentsderivatives are reported in current earnings.


The Company documents all relationships between derivative instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions.  This process includes linking all derivativesderivative instruments that are designated as fair value hedges to specific assets and liabilities in the Consolidated Balance Sheets and linking cash flow hedges to specific forecasted transactions or variability of cash flow.


The Company also assesses, both at the hedge'shedge’s inception and on an ongoing basis, whether the designated derivative instruments that are used in hedging transactions are highly effective in offsetting changes in cash flow or fair values of hedged items.  When a derivative instrument is determined not to be highly effective as a hedge or the underlying hedged transaction is no longer probable of occurring, hedge accounting is discontinued prospectively in accordance with the derecognition criteria for hedge accounting.

TABLE OF CONTENTS
INDEX
The Company primarily executes derivative contracts with major financial institutions.  These counterparties expose the Company to credit risk in the event of non-performance.  The amount of such exposure is limited to the fair value of the contract plus the unpaid portion of amounts due to the Company pursuant to terms of the derivative instruments, if any.  If a downgrade in the credit rating of these counterparties occurs, management believes that this exposure is mitigated by provisions in the derivative arrangements which allow for the legal right of offset of any amounts due to the Company from the counterparties with any amounts payable to the counterparties by the Company.  As a result, management considers the risk of loss from counterparty default to be minimal.  See "Note 6Note 7 – Derivative Instruments and Hedging Activities"Activities for additional information.



Fair Value of Financial Instruments


The carrying amounts for cash and cash equivalents, accounts receivable, and accounts payable approximate fair value due to the short-term maturity of these instruments.
 
The fair value of long-term debt at December 31, 201628, 2019 approximates the carrying value on that date.  The estimated fair values were determined based on quoted market prices and the current rates offered for debt with similar terms and maturities.  The fair value of long-term debt is classified as level 2 within the fair value hierarchy.  This classification is defined as a fair value determined using market-based inputs other than quoted prices that are observable for the liability, either directly or indirectly.  Outstanding borrowings have variable interest rates that re-price frequently at current market rates.


Foreign Currency Translation


For foreign subsidiaries infor which the functional currency is not the U.S. dollar, balance sheet accounts are translated at exchange rates in effect at the end of the year and income statement accounts are translated at average exchange rates for the year.  Translation gains and losses are included in equity as a component of AOCI.  Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are recognized in selling, general, and administrative expense in the Consolidated Statements of Income. Included in the Consolidated Statements of Income were net transaction gains of $0.2 million in 2019, losses of $1.0 million in 2018, and losses of $0.4 million in 2016, losses of $1.7 million in 2015, and gains of $0.1 million in 2014.2017.


Use of and Changes in Estimates


The preparation of financial statements in conformity with generally accepted accounting principles in the United States (U.S. GAAP) requires management to make estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes.  Management makes its best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include but are not limited to: pension and other postretirement benefit plan obligations, tax liabilities, loss contingencies, litigation claims, environmental reserves, and impairment assessments onof long-lived assets (including goodwill).

Change in Segment Reporting

At the beginning of fiscal year 2016, the Company made changes to its management reporting structure as a result of a change in the way the Chief Executive Officer, who serves as the Chief Operating Decision Maker, manages and evaluates the business, makes key operating decisions, and allocates resources.  Previously, the Company had two reportable segments: Plumbing & Refrigeration and OEM.  During 2016, the Company realigned its operating segments into three reportable segments: Piping Systems, Industrial Metals, and Climate.  Management has recast certain prior year amounts to conform to the current year presentation.  See "Note 3 - Segment Information" for additional information.


Recently Adopted Accounting StandardsStandard


In March 2016,July 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvement to Employee Share-Based Payment Accounting.  The ASU requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled.  It also allows a company to make a policy election to account for forfeitures as they occur.  The guidance is effective for public business entities in interim and fiscal periods beginning after December 15, 2016.  Early adoption is permitted, but all of the guidance must be adopted in the same period. 
F-29

TABLE OF CONTENTS
INDEX
The Company elected to adopt this standard effective December 27, 2015 on a prospective basis.  The impact of the adoption of this standard was as follows:

·Approximately $0.9 million of excess tax benefits were recorded through income tax expense as a discrete item for the year ended December 31, 2016.
·Excess tax benefits were combined with other income tax cash flows within operating cash flows rather than as a financing activity.
·The Company has elected to change its current policy of estimating forfeitures to a policy of recognizing forfeitures as they occur.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Topic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (ASU 2014-15). The ASU requires management to evaluate relevant conditions, events, and certain management plans that are known or reasonable knowable as of the evaluation date when determining whether substantial doubt about an entity's ability to continue as a going concern exists.  If conditions or events raise substantial doubt about an entity's ability to continue as a going concern, the entity is required to make certain disclosures.  The guidance is effective for annual periods ending after December 15, 2016.  The Company adopted ASU 2014-15 effective December 31, 2016 and the adoption had no impact on the Consolidated Financial Statements and related disclosures.

Recently Issued Accounting Standards

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash.  The ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows.  As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows.  The guidance will be applied retrospectively and is effective for public business entities in interim and fiscal periods beginning after December 15, 2017.  Early adoption is permitted.  The Company does not expect the adoption of the standard to have a material impact on its Consolidated Financial Statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (ASU 2016-16).  The ASU requires companies to account for the income tax effects of intercompany transfers of assets other than inventory when the transfer occurs.  Companies will still be required to defer the income tax effects of intercompany inventory transactions in an exception to the income tax accounting guidance.  The guidance is effective for public business entities in annual periods beginning after December 15, 2017.  Early adoption is permitted as of the beginning of an annual period.  The Company is still evaluating the effects that the provisions of ASU 2016-16 will have on its Consolidated Financial Statements.

In February 2016, the FASB issued ASU No. 2016-02,2018-11, Leases (Topic 842)(: Targeted Improvements and ASU 2016-02)No. 2018-10, Codification Improvements to Topic 842, Leases. The ASUASUs clarify how to apply certain aspects of the new leasing standard, ASC 842.  ASC 842 requires an entity to recognize a right-of-use asset and lease liability for all leaseseach lease with termsa term of more than 12 months.  Recognition, measurement and presentation of expenses will depend on classification as a financing or operating lease.  The amendmentsguidance also requirerequires certain quantitative and qualitative disclosures about leasing arrangements.  The Company adopted the ASU during the first quarter of 2019 using a modified retrospective approach and applied the transition provisions at the beginning of the fiscal year. Financial results reported in periods prior to 2018 are unchanged. The Company elected a package of practical expedients, which, among other things, does not require the reassessment of lease classification. The Company does not separate lease and non-lease components of contracts. The Company implemented a system to identify its entire population of leases and tested the population for completeness. As of the effective date, the Company recognized noncurrent right-of-use assets of $29.5 million and corresponding current and noncurrent lease liabilities of $4.8 million and $25.4 million, respectively. As of the adoption date of ASC 842, discount rates for existing leases were based on an estimate of the Company’s incremental borrowing rate, adjusted for the term of the lease.

Recently Issued Accounting Standards

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Disclosure Framework - Measurement of Credit Losses on Financial Instruments. The ASU significantly changes the current incurred credit loss model under U.S. GAAP, which delays recognizing credit losses until it is probable a loss has been incurred to a current expected credit losses model which requires immediate recognition of management estimates of credit losses. The ASU will be effective for the annual period beginning in 2020. The updated guidance requires retrospective adoption, and early adoption is permitted. The Company does not expect the adoption of the ASU to have a material impact on its Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. For employers that sponsor defined benefit pension and/or other postretirement benefit plans, the ASU eliminates requirements for certain


disclosures that are no longer considered cost beneficial, requires new disclosures related to the weighted-average interest crediting rate for cash balance plans and explanations for significant gains and losses related to changes in benefit obligations, and clarifies the requirements for entities that provide aggregate disclosures for two or more plans. The ASU will be effective for the annual period beginning in 2020. The updated guidance requires retrospective adoption, and early adoption is permitted. The Company does not expect the adoption of the ASU to have a material impact on its Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The ASU eliminates requirements to disclose the amount and reasons for transfers between level 1 and level 2 of the fair value hierarchy, but requires public companies to disclose changes in unrealized gains and losses for the period included in other comprehensive income (OCI) for recurring level 3 fair value measurements or instruments held at the end of the reporting period and the range and weighted average used to develop significant unobservable inputs for level 3 fair value measurements. The ASU will be effective for interim and fiscalannual periods beginning after December 15, 2018.  Early adoptionin 2020. An entity is permitted.permitted to early adopt either the entire standard or only the provisions that eliminate or modify requirements, and can elect to early adopt in interim periods. The updated guidance requires a modified retrospective adoption.on changes in unrealized gains and losses for the period included in OCI for recurring level 3 measurements, the range and weighted average of significant unobservable inputs used to develop level 3 fair value measurements, and the narrative description of measurement uncertainty is applied prospectively. All other amendments should be applied retrospectively. The Company is still evaluatingdoes not expect the effects thatadoption of the provision of ASU 2016-02 willto have a material impact on its Consolidated Financial Statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09).  The ASU will supersede virtually all existing revenue recognition guidance under U.S. GAAP and will be effective for annual reporting periods beginning after December 15, 2017.  The fundamental principles of the new guidance are that companies should recognize revenue in a manner that reflects the timing of the transfer of services to customers and the amount of revenue recognized reflects the consideration that a company expects to receive for the goods and services provided.  The new guidance establishes a five-step approach for the recognition of revenue.  The Company is in the process of evaluating the impact of ASU 2014-09 on its Consolidated Financial Statements.

TABLE OF CONTENTS
INDEX

During 2016, inventory quantities valued using the LIFO method declined, which resulted in liquidation of LIFO inventory layers.  This liquidation resulted primarily from intercompany sales; therefore $2.5 million of the $3.3 million loss related to the LIFO liquidation was deferred.  The deferred loss will increase cost of goods sold in the first quarter of 2017 when the inventory is sold to third parties.


At the end of 20162019 and 2015,2018, the FIFO value of inventory consigned to others was $2.5$5.5 million and $3.7$5.1 million, respectively.

Note 67 – Derivative Instruments and Hedging Activities


The Company'sCompany’s earnings and cash flows are subject to fluctuations due to changes in commodity prices, foreign currency exchange rates, and interest rates.  The Company uses derivative instruments such as commodity futures contracts, foreign currency forward contracts, and interest rate swaps to manage these exposures.



Commodity Futures Contracts


Copper and brass represent the largest component of the Company'sCompany’s variable costs of production.  The cost of these materials is subject to global market fluctuations caused by factors beyond the Company'sCompany’s control.  The Company occasionally enters into forward fixed-price arrangements with certain customers; the risk of these arrangements is generally managed with commodity futures contracts.  These futures contracts have been designated as cash flow hedges.  


At December 31, 2016,28, 2019, the Company held open futures contracts to purchase approximately $10.2$21.3 million of copper over the next 12 months related to fixed price sales orders.  The fair value of those futures contracts was a $0.8$1.4 million net gain position, which was determined by obtaining quoted market prices (level 1 within the fair value hierarchy).  In the next twelve12 months, the Company will reclassify into earnings realized gains or losses relating to cash flow hedges.  At December 31, 2016,28, 2019, this amount was approximately $0.3 million of deferred net gains, net of tax.


The Company may also enter into futures contracts to protect the value of inventory against market fluctuations.  At December 31, 2016,28, 2019, the Company held open futures contracts to sell approximately $28.7$1.9 million of copper over the next threefive months related to copper inventory.  The fair value of those futures contracts was a $0.3$0.1 million net loss position, which was determined by obtaining quoted market prices (level 1 within the fair value hierarchy).

Interest Rate Swap

On February 20, 2013, the Company entered into a two-year forward-starting interest rate swap agreement with an effective date of January 12, 2015, and an underlying notional amount of $200.0 million, pursuant to which the Company receives variable interest payments based on one-month LIBOR and pays fixed interest at a rate of 1.4 percent.  Based on the Company's current variable premium pricing on its revolving credit facility, the all-in fixed rate  is 2.49 percent.  The interest rate swap will mature on December 11, 2017, and is structured to offset the interest rate risk associated with the Company's floating-rate, LIBOR-based revolving credit facility.   The swap was designated and accounted for as a cash flow hedge at inception. During the fourth quarter of 2016 the Company discontinued hedge accounting prospectively.

The fair value of the interest rate swap is estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rate and the expected cash flows at the current market interest rate using observable benchmarks for LIBOR forward rates at the end of the period (level 2 within the fair value hierarchy).  Interest payable and receivable under the swap agreement is accrued and recorded as an adjustment to interest expense.  The fair value of the interest rate swap was a $0.8 million loss position recorded in other current liabilities at December 31, 2016, and there was $0.6 million of deferred net losses, net of tax, included in AOCI that are expected to be reclassified into interest expense over the term of the interest rate swap.


The Company presents its derivative assets and liabilities in the Consolidated Balance Sheets on a net basis by counterparty.  The following table summarizes the location and fair value of the derivative instruments and disaggregates the net derivative assets and liabilities into gross components on a contract-by-contract basis:

The Company enters into futures and forward contracts that closely match the terms of the underlying transactions.  As a result, the ineffective portion of the qualifying open hedge contracts through December 31, 201628, 2019 was not material to the Consolidated Statements of Income.


The Company primarily enters into International Swaps and Derivatives Association master netting agreements with major financial institutions that permit the net settlement of amounts owed under their respective derivative contracts.  Under these master netting agreements, net settlement generally permits the Company or the counterparty to determine the net amount payable for contracts due on the same date and in the same currency for similar types of derivative transactions.  The master netting agreements generally also provide for net settlement of all outstanding contracts with the counterparty in the case of an event of default or a termination event.  The Company does not offset fair value amounts for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral.  At December 31, 201628, 2019 and December 26, 2015,29, 2018, the Company had recorded restricted cash in other current assets of $1.4$0.2 million and $2.6$3.6 million, respectively, as collateral related to open derivative contracts under the master netting arrangements.

Subordinated Debentures

On March 9, 2017, the Company madedistributed a loan to MCTC Investment Fund, LLC (Investment Fund) under a qualified New Markets Tax Credit (NMTC) program.  The NMTC program was provided forspecial dividend of $3.00 in the Community Renewal Tax Relief Act of 2000 (Act)cash and is intended to induce capital investment$5.00 in qualified lower income communities.  The Act permits taxpayers to claim credits against their Federal income taxes for up to 39% of qualified investments in the equity of community development entities (CDEs).  CDEs are privately managed investment institutions that are certified to make qualified low-income community investments.

In connection with the financing, the Company loaned $13.7 million aggregate principal amount of a 1.0% loan (Leverage Loan)the Company’s 6% Subordinated Debentures (Debentures) due October 17, 2041,March 1, 2027 for each share of common stock outstanding. Interest on the Debentures is payable semiannually on September 1 and March 1.

The Debentures are subordinated to the Investment Fund.  Additionally, Wells Fargo contributed $6.6 million to the Investment Fund, and as such, Wells Fargo is entitled to substantially all other funded debt of the benefits derived fromCompany and are callable, in whole or in part, at any time at the NMTCs.  The Investment Fund then contributed the proceeds to certain CDEs, which, in turn, loaned the funds on similar terms as the Leverage Loan to Mueller Copper Tube Company, Inc. (MCTC) an indirect, wholly-owned subsidiaryoption of the Company.  The proceeds of the loans from the CDEs, including loans representing the capital contribution made by Wells Fargo, net of syndication fees, are restricted for use on the modernization project.  At December 31, 2016, after qualifying capital expenditures, MCTC held restricted cash of $6.6 million, which is included in other current assets in the accompanying Consolidated Balance Sheets.

The NMTC isCompany, subject to 100% recapture for a period of seven years as provided indeclining call premiums during the Internal Revenue Code.first five years. The Company is requiredDebentures also grant each holder the right to comply with various regulations and contractual provisions that apply to the NMTC arrangement.  Non-compliance with applicable requirements could result in projected tax benefits not being realized and, therefore, require the Company to indemnify Wells Fargo for any loss or recapturerepurchase such holder’s Debentures in the event of NMTCs relateda change in control at declining repurchase premiums during the first five years. The Debentures may be redeemed, subject to the financing until such time as the Company's obligation to deliver tax benefits is relieved.  The Company does not anticipate any credit recaptures will be required in connection with this arrangement.  This transaction also includes a put/call provision whereby the Company may be obligated or entitled to repurchase Wells Fargo's interest in the Investment Fund.  The Company believes that Wells Fargo will exercise the put option in October 2023,conditions set forth above, at the endfollowing redemption price (expressed as a percentage of principal amount) plus any accrued but unpaid interest to, but excluding, the recapture period.  The value attributed to the put/call is negligible.redemption date:


The Company has determined that
If redeemed during the financing arrangement with the Investment Fund and CDEs is a variable interest entity (VIE), and that it is the primary beneficiary of the VIE.  This conclusion was reached based on the following:12-month period beginning March 9:

·The ongoing activities of the VIE, collecting and remitting interest and fees, and NMTC compliance were all considered in the initial design and are not expected to significantly affect economic performance throughout the life of the VIE;
·Contractual arrangements obligate the Company to comply with NMTC rules and regulations and provide various other guarantees to the Investment Fund and CDEs;
·Wells Fargo lacks a material interest in the underling economics of the project; and
·The Company is obligated to absorb losses of the VIE.

Because the Company is the primary beneficiary of the VIE, it has been included in the Company's Consolidated Financial Statements.  Wells Fargo's contribution of $6.6 million was initially recorded as restricted cash and its interest in the Investment Fund is included in other liabilities.

The Company'sCompany’s Mexican postretirement plans use the rate of compensation increase in the benefit formulas.  Past service in the U.K. pension plan will be adjusted for the effects of inflation.  All other pension and postretirement plans use benefit formulas based on length of service.


The annual assumed rate of increase in the per capita cost of covered benefits (i.e., health care cost trend rate) is assumed to range from 6.84.0 to 8.37.0 percent for 2017,2020, gradually decrease to 3.04.1 percent through 2036,2040, and remain at that level thereafter.  The health care cost trend rate assumption does not have a significant effect on the amounts reported.


Pension Assets


The weighted average asset allocation of the Company'sCompany’s pension fund assets are as follows:

  Pension Plan Assets

At December 31, 2016,28, 2019, the long-term target allocation, by asset category, of assets of the Company'sCompany’s defined benefit pension plans was: (i) fixed income securities – at least 60 percent; (ii) equity securities, including equity index funds – not more than 30 percent; and (iii) alternative investments – not more than 5 percent.


The pension plan obligations are long-term and, accordingly, the plan assets are invested for the long-term.  Plan assets are monitored periodically.  Based upon results, investment managers and/or asset classes are redeployed when considered necessary.  None of the plans'plans’ assets are expected to be returned to the Company during the next fiscal year.  The assets of the plans do not include investments in securities issued by the Company.  


The estimated rates of return on plan assets are the expected future long-term rates of earnings on plan assets and are forward-looking assumptions that materially affect pension cost.  Establishing the expected future rates of return on pension assets is a judgmental matter.  The Company reviews the expected long-term rates of return on an annual basis and revises as appropriate.  The expected long-term rate of return on plan assets was 5.563.84 percent for 20162019 and 5.595.05 percent in 2015.2018.


The Company'sCompany’s investments for its pension plans are reported at fair value.  The following methods and assumptions were used to estimate the fair value of the Company'sCompany’s plan asset investments:


Cash and money market funds –Valued at cost, which approximates fair value.


Common stock – Valued at the closing price reported on the active market on which the individual securities are traded.

Mutual funds – Valued at the net asset value of shares held by the plans at December 31, 201628, 2019 and December 26, 2015,29, 2018, respectively, based upon quoted market prices.


Limited partnerships –Limited partnerships include investments in various Cayman Island multi-strategy hedge funds.  The plans'plans’ investments in limited partnerships are valued at the estimated fair value of the class shares owned by the plans based upon the equity in the estimated fair value of those shares.  The estimated fair values of the limited partnerships are determined by the investment managers.  In determining fair value, the investment managers of the limited partnerships utilize the estimated net asset valuations of the underlying investment entities.  The underlying investment entities value securities and other financial instruments on a mark-to-market or estimated fair value basis.  The estimated fair value is determined by the investment managers based upon, among other things, the type of investments, purchase price, marketability, current financial condition, operating results, and other information.  The estimated fair values of substantially all of the investments of the underlying investment entities, which may include securities for which prices are not readily available, are determined by the investment managers or management of the respective underlying investment entities and may not reflect amounts that could be realized upon immediate sale.  Accordingly, the estimated fair values may differ significantly from the values that would have been used had a ready market existed for these investments.

Multiemployer Plan


The Company contributes to the IAM National Pension Fund, National Pension Plan (IAM Plan), a multiemployer defined benefit plan.  Participation in the IAM Plan was negotiated under the terms of two2 collective bargaining agreements in Port Huron, Michigan, the Local 218 IAM and Local 44 UAW that expire on May 5, 20197, 2023 and July 21, 2019,June 26, 2022, respectively.  The Employer Identification Number for this plan is 51-6031295.


The risks of participating in multiemployer plans are different from single-employer plans in the following aspects:  (i) assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers; (ii) if a participating employer stops contributing to the plan, the underfunded obligations of the plan may be borne by the remaining participating employers; (iii) if the Company chooses to stop participating in the plan, the Company may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.



The Company makes contributions to the IAM Plan trusts that cover certain union employees; contributions by employees are not permitted.  Contributions to the IAM Plan were approximately $1.2 million in 2019, $1.3 million in 2018, and $1.1 million in 2016, $1.1 million in 2015, and $1.0 million in 2014.2017.  The Company'sCompany’s contributions are less than five5 percent of total employer contributions made to the IAM Plan indicated in the most recently filed Form 5500.


Under the Pension Protection Act of 2006, the IAM Plan'sPlan’s actuary must certify the plan'splan’s zone status annually.  Plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded.  If a plan is determined to be in endangered status, red zone or yellow zone, the plan'splan’s trustees must develop a formal plan of corrective action, a Financial Improvement Plan and/or a Rehabilitation Plan.  While the IAM Plan remains well-funded at 89 percent, for 2019, it has been certified in the yellow zone due to a declining credit balance. However, as a result of a challenging investment environment and the decline of the IAM Plan’s credit balance, the IAM National Pension Plan Board of Trustees has voluntarily elected to place the IAM Plan in the red zone for 2019. The action was taken to protect the IAM Plan’s participants’ core retirement benefits and strengthen the IAM Plan’s financial health over the long term. For 2016 and 20152018, the IAM Plan was determined to have green zone status; therefore, no formal plan of corrective action is either pending or has been implemented.status.

401(k) Plans


The Company sponsors voluntary employee savings plans that qualify under Section 401(k) of the Internal Revenue Code of 1986.  Compensation expense for the Company'sCompany’s matching contribution to the 401(k) plans was $5.2$5.4 million in 2016, $4.22019, $5.1 million in 2015,2018, and $4.1$5.1 million in 2014.2017.  The Company match is a cash contribution.  Participants direct the investment of their account balances by allocating among a range of asset classes including mutual funds (equity, fixed income, and balanced funds) and money market funds.  The plans do not allow direct investment in securities issued by the Company.


UMWA Benefit Plans


In October 1992, the Coal Industry Retiree Health Benefit Act of 1992 (1992 Act) was enacted.  The 1992 Act mandates a method of providing for postretirement benefits to the United Mine Workers of America (UMWA) current and retired employees, including some retirees who were never employed by the Company.  In October 1993, beneficiaries were assigned to the Company and the Company began its mandated contributions to the UMWA Combined Benefit Fund, a multiemployer trust.  Beginning in 1994, the Company was required to make contributions for assigned beneficiaries under an additional multiemployer trust created by the 1992 Act, the UMWA 1992 Benefit Plan.  The ultimate amount of the Company'sCompany’s liability under the 1992 Act will vary due to factors which include, among other things, the validity, interpretation, and regulation of the 1992 Act, its joint and several obligation, the number of valid beneficiaries assigned, and the extent to which funding for this obligation will be satisfied by transfers of excess assets from the 1950 UMWA pension plan and transfers from the Abandoned Mine Reclamation Fund.  Contributions to the plan were $197$223 thousand, $214$153 thousand, and $249$182 thousand for the years ended 2016, 2015,2019, 2018, and 2014,2017, respectively.

Southeast Kansas Sites


The Kansas Department of Health and Environment (KDHE) has contacted the Company regarding environmental contamination at three3 former smelter sites in Kansas (Altoona, East La Harpe, and Lanyon).  The Company is not a successor to the companies that operated these smelter sites, but is exploring possible settlement with KDHE and other potentially responsible parties (PRP) in order to avoid litigation.

Altoona. Another PRP conducted a site investigation of the Altoona site under a consent decree with KDHE and submitted a removal site evaluation report recommending a remedy.  The remedial design plan, which covers both on-site and certain off-site cleanup costs, was approved by the KDHE in 2016.  Construction of the remedy was completed in 2018.



East La Harpe.At the East La Harpe site, the Company and two2 other PRPs conducted a site study evaluation under KDHE supervision and prepared a site cleanup plan approved by KDHE.  In 2016, the corporate parent (Peabody Energy) of a third party that the Company understands may owe indemnification obligations to one of the other PRPs (Blue Tee) in connection with the East La Harpe site filed for protection under Chapter 11 of the U.S. Bankruptcy Code.  KDHE has extended the deadline for the PRPs to develop a repository design plan to allow for wetlands permitting to take place.  In December 2018, KDHE provided a draft agreement which contemplates the use of funds KDHE obtained from two other parties (Peabody Energy and Blue Tee) to fund part of the remediation, and removes Blue Tee from the PRPs’ agreement with KDHE. The Company is currently negotiating the terms of the draft agreement.

Lanyon.With respect to the Lanyon Site, in 2016, the Company received a general notice letter from the United States Environmental Protection Agency (EPA) asserting that the Company is a PRP, which the Company has denied. EPA issued an interim record of decision in 2017 and has been remediating properties at the site.
The Company'sCompany’s reserve for its proportionate share of the remediation costs associated with thethese 3 Southeast Kansas sites is $5.6 million. EPA issued an interim record of decision in 2017 and has been remediating properties at the site.

Shasta Area Mine Sites


Mining Remedial Recovery Company (MRRC), a wholly owned subsidiary, owns certain inactive mines in Shasta County, California.  MRRC has continued a program, begun in the late 1980s, of implementing various remedial measures, including sealing mine portals with concrete plugs in portals whichthat were discharging water.  The sealing program achieved significant reductions in the metal load in discharges from these adits; however, additional reductions are required pursuant to an order issued by the California Regional Water Quality Control Board (QCB).  In response to a 1996 QCB Order, MRRC completed a feasibility study in 1997 describing measures designed to mitigate the effects of acid rock drainage.  In December 1998, the QCB modified the 1996 order extending MRRC'sMRRC’s time to comply with water quality standards.  In September 2002, the QCB adopted a new order requiring MRRC to adopt Best Management Practices (BMP) to control discharges of acid mine drainage, and again extended the time to comply with water quality standards until September 2007.  During that time, implementation of BMP further reduced impacts of acid rock drainage; however, full compliance has not been achieved.  The QCB is presently renewing MRRC'sMRRC’s discharge permit and will concurrently issue a new order.  It is expected that the new ten-year10-year permit will include an order requiring continued implementation of BMP through 20252030 to address residual discharges of acid rock drainage.  At this site, MRRC spent approximately $1.2$1.9 million from 20142017 through 20162019 for remediation, and currently estimates that it will spend between approximately $13.2$12.7 million and $20.9$17.7 million over the next 30 years.


Lead Refinery Site


U.S.S. Lead Refinery, Inc. (Lead Refinery), a non-operating wholly owned subsidiary of MRRC, has conducted corrective action and interim remedial activities (collectively, Site Activities) at Lead Refinery'sRefinery’s East Chicago, Indiana site pursuant to the Resource Conservation and Recovery Act since December 1996.  Although the Site Activities have been substantially concluded, Lead Refinery is required to perform monitoring and maintenance-related activities pursuant to a post-closure permit issued by the Indiana Department of Environmental Management effective as of March 2, 2013.  Lead Refinery spent approximately $0.5$0.7 million from 20142017 through 20162019 with respect to this site.  Approximate costs to comply with the post-closure permit, including associated general and administrative costs, are estimated at between $2.1$1.8 million and $4.7$2.3 million over the next 2017 years.
 
On April 9, 2009, pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the U.S. Environmental Protection Agency (EPA) added the Lead Refinery site and surrounding properties to the National Priorities List (NPL).  On July 17, 2009, Lead Refinery received a written notice from the EPA indicating that it may be a PRP under CERCLA due to the release or threat of release of hazardous substances including lead into properties surrounding the Lead Refinery NPL site.  The EPA identified two other PRPs in connection with that matter.  In November 2012, the EPA adopted a remedy for the surrounding properties and in September 2014, the EPA announced that it had entered into a settlement with the two other PRPs whereby they will pay approximately $26.0 million to fund the cleanup of approximately 300 properties surrounding the Lead Refinery NPL site (zones 1 and 3 of operable unit 1) and perform certain remedial action tasks.


On November 8, 2016, the Company, its subsidiary Arava Natural Resources Company, Inc. (Arava), and Arava'sArava’s subsidiary MRRC each received general notice letters from the EPA asserting that they may be PRPs in connection with the Lead Refinery NPL site.  The Company, Arava, and MRRC have denied liability for any remedial action and response costs associated with the Lead Refinery NPL site.  In June 2017, the EPA requested that Lead Refinery conduct, and the Company fund, a remedial investigation and feasibility study of operable unit 2 of the Lead Refinery NPL site pursuant to a proposed administrative settlement agreement and order on consent. The Company and Lead Refinery entered into that agreement in September 2017. The Company


has made a capital contribution to Lead Refinery to conduct the remedial investigation and feasibility study with respect to operable unit 2 and has provided financial assurance in the amount of $1.0 million. The EPA has also asserted its position that Mueller is a responsible party for the Lead Refinery NPL site, and accordingly is responsible for a share of remedial action and response costs at the site and in the adjacent residential area.

In January 2018, the EPA issued 2 unilateral administrative orders (UAOs) directing the Company, Lead Refinery, and four other PRPs to conduct soil and interior remediation of certain residences at the Lead Refinery NPL site (zones 2 and 3 of operable unit 1). The Company and Lead Refinery have reached agreement with the four other PRPs to implement these two UAOs, with the Company agreeing to pay, on an interim basis, (i) an estimated $4.5 million (subject to potential change through a future reallocation process) of the approximately $25.0 million the PRPs currently estimate it will cost to implement the UAOs, which estimate is subject to change, and (ii) $2.0 million relating to past costs incurred by other PRPs for work conducted at the site, as well as the possibility of up to $0.7 million in further payments for ongoing work by those PRPs, $0.4 million of which has been incurred by those PRPs and paid for by the Company to date.  As of year-end, the Company has made payments of approximately $7.0 million related to the aforementioned agreement with the other PRPs. The Company disputes that it was properly named in the UAOs, and has reserved its rights to petition the EPA for reimbursement of any costs incurred to comply with the UAOs upon the completion of the work required therein.  In October 2017, a group of private plaintiffs sued the Company, Arava, MRRC, and Lead Refinery, along with other defendants, in a private tort action relating to the site; the Company, Arava, and MRRC were voluntarily dismissed from that litigation without prejudice in March 2018.  A second civil action asserting similar claims was filed against the Company, Arava, MRRC, and Lead Refinery in September 2018. At this juncture, the Company is unable to determine the likelihood of a material adverse outcome or the amount or range of a potential loss in excess of the current reserve with respect to any remedial action or litigation relating to the Lead Refinery NPL site, either at Lead Refinery’s former operating site (operable unit 2) or the adjacent residential area (operable unit 1), including, but not limited to, EPA oversight costs for which EPA may attempt to seek reimbursement from the Company, and past costs for which other PRPs may attempt to seek contribution from the Company.

Bonita Peak Mining District

Following an August 2015 spill from the Gold King Mine into the Animas River near Silverton, Colorado, the EPA listed the Bonita Peak Mining District on the NPL.  Said listing was finalized in September 2016.  The Bonita Peak Mining District encompasses 48 mining sites within the Animas River watershed, including the Sunnyside Mine, the American Tunnel, and the Sunbank Group.  On or about July 25, 2017, Washington Mining Company (Washington Mining) (a wholly-owned subsidiary of the Company’s wholly-owned subsidiary, Arava), received a general notice letter from the EPA stating that Washington Mining may be a PRP under CERCLA in connection with the Bonita Peak Mining District site and therefore responsible for the remediation of certain portions of the site, along with related costs incurred by the EPA.  Shortly thereafter, the Company received a substantively identical letter asserting that it may be a PRP at the site and similarly responsible for the cleanup of certain portions of the site.  The general notice letters identify one other PRP at the site, and do not require specific action by Washington Mining or the Company at this time.  At this juncture, the Company is unable to determine the likelihood of a materially adverse outcome or the amount or range of a potential loss with respect to any remedial action related to the Lead RefineryBonita Peak Mining District NPL site.

Mueller Copper Tube Products, Inc.


In 1999, Mueller Copper Tube Products, Inc. (MCTP), a wholly owned subsidiary, commenced a cleanup and remediation of soil and groundwater at its Wynne, Arkansas plant to remove trichloroethylene, a cleaning solvent formerly used by MCTP.  On August 30, 2000, MCTP received approval of its Final Comprehensive Investigation Report and Storm Water Drainage Investigation Report addressing the treatment of soils and groundwater from the Arkansas Department of Environmental Quality (ADEQ).  The Company established a reserve for this project in connection with the acquisition of MCTP in 1998.  Effective November 17, 2008, MCTP entered into a Settlement Agreement and Administrative Order by Consent to submit a Supplemental Investigation Work Plan (SIWP) and subsequent Final Remediation Work Plan (RWP) for the site.  By letter dated January 20, 2010, ADEQ approved the SIWP as submitted, with changes acceptable to the Company.  On December 16, 2011, MCTP entered into an amended Administrative Order by Consent to prepare and implement a revised RWP regarding final remediation for the Site.  The remediation system was activated in February 2014.  Costs to implement the work plans, including associated general and administrative costs, are estimated to approximate $0.9$0.6 million to $1.4$0.9 million over the next ninesix years.

United States Department of Commerce Antidumping Review


On December 24, 2008, the Department of Commerce (DOC) initiated an antidumping administrative review of the antidumping duty order covering circular welded non-alloy steel pipe and tube from Mexico for the November 1, 2007  through October 31,


2008 period of review.  The DOC selected Mueller Comercial as a respondent in the review.  On April 19, 2010, the DOC published the final results of the review and assigned Mueller Comercial an antidumping duty rate of 48.33 percent.  On May 25, 2010, the Company appealed the final results to the U.S. Court of International Trade (CIT).  On December 16, 2011, the CIT issued a decision remanding the Department'sDepartment’s final results.  While the matter was still pending, the Company and the United States reached an agreement to settle the appeal.  Subject to the conditions of the agreement, the Company anticipated that certain of its subsidiaries willwould incur antidumping duties on subject imports made during the period of review and, as such, established a reserve for this matter.  After the lapse of the statutory period of time during which U.S. Customs and Border Protection (CBP) was required, but failed, to liquidate the entries at the settled rate, the Company released the reserve.  Between October 30, 2015 and November 27, 2015, CBP sent a series of invoices to Southland Pipe Nipples Co., Inc. (Southland), requesting payment of approximately $3.0 million in duties and interest in connection with 795 import entries made during the November 1, 2007 through October 31, 2008 period.  On January 26, 2016 and January 27, 2016, Southland filed protests with CBP in connection with these invoices, noting that CBP'sCBP’s asserted claims were not made in accordance with applicable law, including statutory provisions governing deemed liquidation. The Company believes in the merits of the legal objections raised in Southland'sSouthland’s protests, and CBP'sCBP’s response to Southland'sSouthland’s protests is currently pending. Given the procedural posture of and issuedissues raised by this legal dispute, the Company cannot estimate the amount of potential duty liability, if any, that may result from CBP'sCBP’s asserted claims.


Equal Employment Opportunity Commission Matter

That amount was fully within itsthe limits of the Company’s applicable insurance limits.coverage, and has been paid to claimants designated as eligible by the EEOC. The conciliation process is ongoing.  Due to the procedural stage of this matter,Consent Decree also required the Company is unable to determinetake a series of proactive measures to cultivate a work environment free from unlawful discrimination. Those measures have included, among others, assistance with the likelihoodidentification of a material adverse outcomepotential claimants, employee, supervisory and managerial training regarding employee rights under the ADA, revised practices and procedures concerning reasonable workplace accommodations as required by the ADA, and related reporting and recordkeeping.

During 2015,rate from 35 percent to 21 percent, required companies to pay a one-time transition tax on the accumulated earnings of certain foreign subsidiaries, and created new taxes on certain foreign-sourced earnings. The Company applied the guidance in Staff Accounting Bulletin No. 118 in accounting for the enactment date effects of the Act. At December 30, 2017, the Company had an adjustment tomade a reasonable estimate of the one-time transition tax on accumulated foreign earnings as well as the impact of the Act on its existing deferred tax balances. During the fourth quarter of 2018, the Company completed its accounting for all of the enactment-date income tax effects of the Act.

The one-time transition tax is based on the Company’s total post-1986 earnings and profits (E&P) for which the accrual of U.S. income taxes had previously been deferred. The Company recorded a provisional amount for its one-time transition tax liability, resulting in an increase in income tax expense of $4.2$12.9 million, or seven22 cents per diluted share, resulting from the acquisition of a foreign subsidiary.

at December 30, 2017. During 2014,2018, the Company releasedcontinued to refine its calculation of the transition tax. Following the completion of this analysis, the Company recorded a valuation allowancereduction to income tax expense of $5.7$4.4 million, or 10eight cents per diluted share, to reduce this liability. During 2019, the Treasury Department finalized regulations related to the calculation of the transition tax, the impact of which was immaterial to the financial statements. The Company continues to assert that the undistributed earnings of most of its foreign subsidiaries are permanently reinvested. No taxes have been accrued with respect to these undistributed earnings or any outside basis differences.

On December 30, 2017, the Company remeasured certain statedeferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent, resulting in an income tax credits.  Asbenefit of $12.1 million, or 21 cents per diluted share. The Company has concluded that no further adjustment is needed related to this remeasurement.

The global intangible low-taxed income (GILTI) provisions of the Act impose a result of legislative changes enactedtax on the GILTI earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in 2014,future years or provide for the tax expense related to GILTI in the year the tax is incurred. The Company expectshas elected to be ableprovide for the tax expense related to use such credits withinGILTI in the foreseeable future.year the tax is incurred.

The Company includes interest and penalties related to income tax matters as a component of income tax expense.  The income tax expense related to penalties and interest was immaterial in 2016, 2015,2019, 2018, and 2014.2017. 

The Internal Revenue Service completed its audit of the Company's 2013 tax return in 2016 and completed its audit of the Company's 2012 tax return during 2014, the results of which were immaterial to the Consolidated Financial Statements.  The Company is currently under audit in various other jurisdictions.


The statute of limitations is still open for the Company'sCompany’s federal tax return and most state income tax returns for 20132015 and all subsequent years.  The statutes of limitations for certainmost state returns are open for 2016 and all subsequent years, and some state and foreign returns are also open for some earlier tax years due to differing statute periods. The Internal Revenue Service is currently auditing the Company’s 2015 and 2017 tax returns.  While the Company believes that it is adequately reserved for possible audit adjustments, the final resolution of these examinations cannot be determined with certainty and could result in final settlements that differ from current estimates.

Note 1617 – Stock-Based Compensation


The Company has in effect stock incentive plans under which stock-based awards have been granted to certain employees and members of its Board of Directors.  Under these existing plans, the Company may grant options to purchase shares of common stock at prices not less than the fair market value of the stock on the grant date, of grant, as well as restricted stock awards.  Generally, the awards vest within five years from the date of grant.grant date.  Any unexercised options expire after not more than ten years.  


During the years ended December 31, 2016,28, 2019, December 26, 2015,29, 2018, and December 27, 2014,30, 2017, the Company recognized stock-based compensation, as a component of selling, general, and administrative expense, in its Consolidated Statements of Income of $6.4$8.7 million, $6.2$8.0 million, and $6.3$7.5 million, respectively.  


Stock Options
The fair value of each option is estimated as a single award and amortized into compensation expense on a straight-line or accrual basis over its vesting period based on its vesting schedule.  The weighted average grant-date fair value of options granted during 2016, 2015,2019, 2018, and 20142017 was $7.87, $7.58,$8.78, $9.64, and $9.00,$9.38, respectively.


The Company estimates the fair value of all stock option awards as of the grant date by applying the Black-Scholes-Merton option pricing model.  The use of this valuation model in the determination of compensation expense involves certain assumptions that are judgmental and/or highly sensitive including the expected life of the option, stock price volatility, risk-free interest rate, and dividend yield.  Additionally, forfeitures are not estimated at the time of valuation; they are recognized as they occur. The weighted average of key assumptions used in determining the fair value of options granted and a discussion of the methodology used to develop each assumption are as follows:
 
 2016 2015 2014  2019 2018 2017
             
Expected term 6.7 years  5.5 years  5.6 years  7.8 years
 7.6 years
 7.7 years
Expected price volatility  25.6%   26.2%   34.3%  28.6% 27.2% 28.9%
Risk-free interest rate  1.6%   1.7%   1.7%  2.4% 2.9% 2.1%
Dividend yield  1.0%   0.9%   1.0%  1.4% 1.3% 1.3%



Expected term – This is the period of time estimated based on historical experience over which the options granted are expected to remain outstanding.  An increase in the expected term will increase compensation expense.


Expected price volatility – This is a measure of the amount by which a price has fluctuated or is expected to fluctuate.  The Company uses actual historical changes in the market value of its stock to calculate the volatility assumption.  Daily market value changes from the grant date of grant over a past period representative of the expected term of the options are used.  An increase in the expected price volatility rate will increase compensation expense.


Risk-free interest rate – This is the U.S. Treasury rate for the week of the grant, having a term representative of the expected term of the options.  An increase in the risk-free rate will increase compensation expense.

INDEX
Dividend yield – This rate is the annual dividends per share as a percentage of the Company'sCompany’s stock price.  An increase in the dividend yield will decrease compensation expense.


The total intrinsic value of options exercised was $2.5$1.6 million, $3.1$0.9 million, and $3.5$10.2 million in 2016, 2015,2019, 2018, and 2014,2017, respectively.  The total fair value of options that vested was $0.3 million, $0.8 million, and $1.0 million each year in 2016, 2015,2019, 2018, and 2014, respectively.2017.


At December 31, 2016,28, 2019, the aggregate intrinsic value of all outstanding options was $19.5$6.3 million with a weighted average remaining contractual term of 5.05.5 years.  Of the outstanding options, 655613 thousand are currently exercisable with an aggregate intrinsic value of $15.8$5.8 million, a weighted average exercise price of $16.02,$22.34, and a weighted average remaining contractual term of 3.24.5 years.  


The total compensation expense not yet recognized related to unvested options at December 31, 201628, 2019 was $1.4$1.5 million, with an average expense recognition period of 2.33.0 years.



Restricted Stock Awards


The fair value of each restricted stock award equals the fair value of the Company'sCompany’s stock on the grant date and is amortized into compensation expense on a straight-line or accrual basis over its vesting period based on its vesting schedule.  The weighted average grant-date fair value of awards granted during 2016, 2015,2019, 2018, and 20142017 was $34.04, $32.54,$28.82, $32.04, and $28.80,$30.97, respectively.


The aggregate intrinsic value of outstanding and unvested awards was $28.4$33.7 million at December 31, 2016.28, 2019.  Total compensation expense for restricted stock awards not yet recognized was $15.9$18.7 million with an average expense recognition period of 3.43.2 years.  The total fair value of awards that vested was $4.7$5.6 million, $4.8$3.7 million, and $4.2$3.5 million in 2016, 2015,2019, 2018, and 2014,2017, respectively.

Defined Benefit Pension Obligation
Description of the Matter 
DescriptionAt December 28, 2019, the aggregate defined benefit pension obligation was $182.2 million, and the fair value of pension plan assets was $183.5 million, resulting in an overfunded defined benefit pension obligation of $1.3 million. As disclosed in Notes 1 and 13 to the consolidated financial statements, the Company recognizes the overfunded or underfunded status of the plans as an asset or liability in the consolidated balance sheets with changes in the funded status recorded through comprehensive income in the year in which those changes occur. The obligations for these plans are actuarially determined and affected by assumptions, including discount rates, expected long-term return on plan assets, and certain employee-related factors such as mortality.

Auditing the defined benefit pension obligation is complex and required the involvement of our actuarial specialists due to the highly judgmental nature of actuarial assumptions (e.g., discount rate, expected return on plan assets, and mortality rate) used in the measurement process and the geographical differences of the plans, which require different considerations for the relevant assumptions based on the respective economic and demographic environments. These assumptions have a significant effect on the projected benefit obligation.
How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of controls that address the measurement and valuation of the defined benefit pension obligation. For example, we tested controls over management’s review of the defined benefit pension obligation, including the significant actuarial assumptions used by management and the related data inputs.

To test the defined benefit pension obligation, our audit procedures included, among others, evaluating the methodology used, the significant actuarial assumptions discussed above and testing the completeness and accuracy of the underlying data, including the participant data used by management.

We involved our actuarial specialist to assist with our procedures. For example, we compared the actuarial assumptions used by management to historical trends and evaluated the change in the defined benefit pension obligation from prior year due to the change in service cost, interest cost, actuarial gains and losses, benefit payments, contributions and other activities. In addition, we evaluated management’s methodology for determining the discount rate that reflects the maturity and duration of the benefit payments that is used to measure the defined benefit pension obligation. As part of this assessment, we compared management’s selected discount rate to an independently developed range of reasonable discount rates. To evaluate the mortality rate assumption, we assessed whether the information is consistent with publicly available information, and whether any market data adjusted for entity-specific factors were applied. Lastly, to evaluate the expected return on plan assets, we assessed whether management’s assumption was consistent with a range of returns for a portfolio of comparative investments.
  
  Valuation of Goodwill - Heatlink Group Reporting Unit
Description of the Matter 
10.12Summary description
At December 28, 2019, the Company’s goodwill was $153.3 million, of which $131.6 million related to the Piping Systems segment which includes the Heatlink Group reporting unit. As disclosed in Notes 1 and 10 to the consolidated financial statements, goodwill is evaluated annually for possible impairment as of the Registrant's 2017 incentive plan for certain key employees.

Auditing management’s annual goodwill impairment test for the Heatlink Group reporting unit was complex and highly judgmental due to Rule 13a-14(a) and Rule 15d-14(a)the significant estimates required to determine the fair value of the Securities Exchange Actreporting unit.

How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of the controls over the goodwill impairment process. For example, we tested controls over management’s review of the significant assumptions used in the reporting unit valuations as well as management’s review around the reasonableness of the data used in these valuations.

To test the estimated fair value of the Heatlink Group reporting unit, we performed audit procedures that included, among others, evaluating methodologies used, involving our valuation specialists in testing the significant assumptions and valuation methodology described above and testing the underlying data used by the Company in its analysis for completeness and accuracy. We compared the significant assumptions used by management to current industry and economic trends, historical results and other guideline companies within the same industry, as well as other relevant factors. We assessed the historical accuracy of management’s estimates and performed sensitivity analyses of significant assumptions to evaluate the change in the fair value of the reporting unit resulting from changes in the inputs and assumptions. We evaluated the incorporation of the applicable assumptions into the model and tested the model’s computational accuracy.

The valuation allowance increased by $11.6 million during 2017 to a balance of $30.3 million as of December 30, 2017.  The change to the valuation allowance was attributable to the recording of valuation allowances against tax attributes generated in 2017 primarily resulting from the Act and increased interest expense in state tax jurisdictions where the Company has no tax liability.
