 z MESSAGE FROM 
OUR CHAIRMAN

To Our Stockholders:

In 2019, Mueller Industries achieved its second consecutive year 
of double-digit operating income growth, a solid performance that 
puts us on track with our ambitious 2024 Strategic Plan. In total, 
Mueller earned $191.4 million in operating income and generated 
$200.5 million in cash from operations on the year. Net income 
for 2019 was $101.0 million, declining slightly from the prior year, 
primarily due to losses incurred related to our Tecumseh investment, 
which included restructuring charges. 

Top-line, net sales ended at $2.4 billion, a 3.1% decline from 2018. 
Net sales, however, were dragged down by a decline in commodity 
prices and reduced volumes in our core U.S. tube and brass rod 
businesses. The average price of copper declined by 7.2% in 
2019. Copper is the principal ingredient in products that make up 
87% of Mueller’s net sales, and as such, declining copper prices 
had a predominant impact on net sales. Notwithstanding, our 
diversification strategy is paying off, as we have benefitted from 
growth in our value-added products and strategic acquisitions. 

“Copper is the principal 
ingredient in products that 
make up 87% of Mueller’s 
net sales”

The majority of our capital spending in 2019 was directed toward 
the general maintenance of business, as well as environmental, 
health, and safety initiatives. Such expenditures remain relatively 
stable and well below depreciation. Investments aimed at reducing 
costs or increasing capacity, such as evolving automation and new 
process technologies, remain vitally important, but were much lower 
in 2019. This spending tends to be more variable — i.e., higher in 
some years, and lower in others. 

We strive to make our workplaces healthier and safer environments 
for our people and the communities in which we operate. Our safety 
record has continued to improve, as we reduced the number of 
accidents per hours worked by 1.7% in 2019. Our incidence rate 
has now been cut by more than half over the past ten years.

 
In other encouraging news, our modernization investments in 
our flagship U.S. operations —our copper tube mill in Fulton, 
Mississippi, and our brass rod mill in Port Huron, Michigan — 
are paying off. In addition to improving capacity, cost, yield and 
quality, we are achieving important environmental benefits. For 
example, at our copper tube mill in Fulton, where water is a 
critical component of the production process, our investments 
have yielded substantial reductions in consumption on a per unit 
of production basis. Furthermore, at both operations, we have 
achieved significant reductions in errant emissions, ranging from 
10% up to 85% for greenhouse gases and certain contaminants 
found in scrap, which we recycle to produce the majority of our 
products.

At Port Huron, the throughput and yield improvements enabled 
us to finally complete the consolidation of all brass rod production 
from two plants into the Port Huron facility during the latter part 
of 2019.  

Capital Allocation

Strong cash generation has long been a hallmark of our financial 
performance. During the past five years, we have generated 
$730 million in cash from operations. For each of the past two 
years, we have achieved considerable growth in free cash flow. 
As a testament to the prudent and balanced manner in which we 
deploy cash, we have returned $600 million to our stockholders 
over the past five years, all while continuing to pay down debt, 
invest in operations, and fund acquisitions.

Our balance sheet is solid, our debt modest, and we have even 
more opportunities to improve.

The Outlook

Our operations span seven countries, and our products are 
sold  and  distributed  in  more  than  a  dozen  more.  Despite 
global uncertainties and geopolitical unrest, we believe that the 
construction markets — which are of particular importance to 
us — will fare better than the average economy in many of the 
regions we serve. The demand for investment in refrigeration/
food preservation and air conditioning/air quality, as well as 
the modernization of water management infrastructure, is on 
the upswing. These trends, if continued, will support Mueller’s 
long term growth, and the Company is well-positioned to take 
advantage of any such opportunities. 

As noted above, our major investments are in the early stages of 
their life cycles, and still have room for further improvement. We 
will continue to strive for higher yields, and enhanced efficiency 
and safety as our people adapt to evolving technologies.

In Closing

We operate with a mindset that preparation equals opportunity. 
We understand that the future is uncertain and that there are 
many influences outside our control. That said, with our 2024 
Strategic Plan as our roadmap, we will incrementally adjust our 
strategies and actions to maximize our performance and results, 
whatever the climate. 

Although acquisitions will remain an important ingredient in our growth 
strategy, we will pursue them opportunistically, and with a sharp 
focus on value. We have built a solid foundation of well-capitalized 
businesses; our balance sheet and cash generation provide us 
strength and flexibility; and we have a diversity of talent, including both 
seasoned industry veterans and motivated, well-trained rising stars, 
driving our businesses. Mindful that wisdom is not something that is 
bought off the shelf, we are grateful for the longevity and loyalty of our 
long-serving employees. We encourage their continued stewardship 
of our Company, as well as their mentorship to our up and comers, 
the next generation of leaders who will propel us into the future.

We conclude 2019 laser-focused on executing our plans and 
generating even higher returns for our stockholders in the coming 
years. Although we have said it before, it bears repeating that the 
engine that makes all of this work is our people. Their commitment 
and work ethic are incredible, and we greatly appreciate them 
and their unending passion to make Mueller Industries the best 
of the best.

Very truly yours,

PROXY SUMMARY
Proposal 3: Advisory Vote to Approve Compensation of Named Executive Officers

 — PROPOSAL 3: ADVISORY VOTE TO APPROVE 

COMPENSATION OF NAMED EXECUTIVE OFFICERS

We are seeking your advisory vote to approve the compensation 
of  our  named  executive  officers  (“NEOs”)  as  disclosed  in 
this proxy  statement. Our executive officers are responsible 
for  achieving  long-term  strategic  goals,  and  as  such,  their 
compensation is weighted toward rewarding long-term value 
creation for stockholders. Beyond base salary and traditional 
benefits, we maintain an annual cash incentive compensation 
program that is driven by a pay-for-performance philosophy and 
based on ambitious performance targets both at the Company 
and business line levels. We also maintain a long-term equity 
incentive compensation program, the primary objective of which 
is to motivate and retain top talent — a particularly vital goal 
given the uniquely competitive industry in which we operate. 

Accordingly, we utilize a combination of extended time-vesting 
schedules and performance-based vesting criteria to encourage 
executives and associates alike to enjoy lengthy tenures at the 
Company, develop industry expertise and relationships, and drive 
our long-term success.

Our emphasis on creating long-term stockholder value is best 
illustrated in the following charts, which show that long-term 
incentive compensation accounts for the largest percentage of 
the NEOs’ overall compensation for 2019. Moreover, a majority 
of the NEOs’ compensation — consisting of target long-term and 
short-term incentive compensation combined — is performance-
based or “at risk.”

 z PROPOSAL 1
 z ELECTION OF DIRECTORS

Eight director nominees will be elected at the Annual Meeting, 
each to serve until the next annual meeting (tentatively scheduled 
for May 6, 2021), or until the election and qualification of their 
successors.  At  the  recommendation  of  the  Nominating  and 
Corporate Governance Committee, the Board has nominated the 
following persons to serve as directors for the term beginning at 
the Annual Meeting: Gregory L. Christopher, Elizabeth Donovan, 
Gennaro  J.  Fulvio,  Gary  S.  Gladstein,  Scott  J.  Goldman, 
John B. Hansen, Terry Hermanson and Charles P. Herzog, Jr. 
(collectively, the “Nominees”). As previously disclosed by the 
Company on July 31, 2019, Paul J. Flaherty will be retiring from 
the Board of Directors at the conclusion of the current term, 
and contemporaneously therewith, the number of directors will 
be reduced to eight. All nominees have consented to stand for 
election and to serve if elected. However, if at the time of the 
Annual Meeting any nominee is unable or declines to serve, the 
individuals named in the proxy will vote the proxy for substitute 
nominees selected by them unless the number of directors has 
been reduced to the number of nominees willing and able to 
serve.

Directors are elected by a plurality of the votes cast, which means 
that the individuals who receive the greatest number of votes 
cast “For” are elected as directors up to the maximum number of 

directors to be chosen at the Annual Meeting. Consequently, any 
shares not voted “For” a particular director (whether as a result of 
a direction to withhold or a broker non-vote) will not be counted 
in such director’s favor.

The Board of Directors has adopted a majority vote policy in 
uncontested  elections.  An  uncontested  election  means  any 
stockholders  meeting  called  for  purposes  of  electing  any 
director(s) in which (i) the number of director nominees for election 
is equal to the number of positions on the Board of Directors to 
be filled through the election to be conducted at such meeting, 
and/or (ii) proxies are being solicited for the election of directors 
solely by the Company. 

The election of directors solicited by this Proxy Statement is an 
uncontested election. In the event that a nominee for election 
in an uncontested election receives a greater number of votes 
“Withheld” for his or her election than votes “For” such election, 
such  nominee  will  tender  an  irrevocable  resignation  to  the 
Nominating and Corporate Governance Committee, which will 
decide whether to accept or reject the resignation and submit 
such recommendation for prompt consideration by the Board of 
Directors no later than ninety (90) days following the uncontested 
election.

 — SELECTING NOMINEES TO THE BOARD

The  Nominating  and  Corporate  Governance  Committee 
considers, among other things, the following criteria in selecting 
and reviewing director nominees:

recommending director nominees, the Committee members take 
into account such factors as they determine appropriate, including 
recommendations made by the Board of Directors.

 z personal and professional integrity, and the highest ethical 

standards;

 z skills, business experience and industry knowledge useful to 
the oversight of the Company based on the perceived needs 
of the Company and the Board at any given time;

 z the ability and willingness to devote the required amount of time 
to the Company’s affairs, including attendance at Board and 
committee meetings;

 z the interest, capacity and willingness to serve the long-term 

interests of the Company; and

 z the lack of any personal or professional relationships that would 
adversely affect a candidate’s ability to serve the best interests 
of the Company and its stockholders.

The Nominating and Corporate Governance Committee also 
assesses the contributions of the Company’s incumbent directors 
in connection with their potential re-nomination. In identifying and 

As reflected in its formal charter, the Nominating and Corporate 
Governance Committee considers the diversity of the Company’s 
Board and employees to be a tremendous asset. The Company 
is committed to maintaining a highly qualified and diverse Board, 
and as such, all candidates are considered regardless of their 
age, gender, race, color of skin, ethnic origin, political affiliation, 
religious preference, sexual orientation, country of origin, physical 
handicaps  or  any  other  category.  These  efforts  to  promote 
diversity are assessed annually to assure that the Board contains 
a balanced and effective mix of individuals capable of advancing 
the Company’s long-term interests.

The Nominating and Corporate Governance Committee does not 
consider individuals nominated by stockholders for election to 
the Board. The Board believes that this is an appropriate policy 
because the Company’s Bylaws allow a qualifying stockholder to 
nominate an individual for election to the Board, said nomination 
of which can be brought directly before a meeting of stockholders.

 z CORPORATE GOVERNANCE

The  Company  adheres  to  an  established  set  of  Corporate 
Governance  Guidelines  for  purposes  of  defining  director 
independence, assigning responsibilities, setting high standards 
of professional and personal conduct, and ensuring compliance 
with such responsibilities and standards. Such Guidelines are 

periodically  reviewed  in  light  of  evolving  trends  in  corporate 
governance  standards,  regulations  and  related  disclosure 
requirements, particularly as adopted by the NYSE and (with 
respect to the Audit Committee), the SEC.

 — DIRECTOR INDEPENDENCE

In order for a director to qualify as “independent,” our Board of 
Directors must affirmatively determine, consistent with NYSE rules, 
that the director has no material relationship with the Company that 
would impair the director’s independence. Our Board of Directors 
undertook its annual review of director independence in February 
2020. In applying the NYSE standards for independence, and 
after considering all relevant facts and circumstances, the Board 
of Directors has affirmatively determined that the Company’s 
current “independent” directors are: Elizabeth Donovan, Paul J. 
Flaherty, Gennaro J. Fulvio, Gary S. Gladstein, Scott J. Goldman, 
John B. Hansen, Terry Hermanson and Charles P. Herzog, Jr. In 
the course of the Board of Directors’ determination regarding 
the independence of each non-management director, the Board 
considered for:

 z Mr. Flaherty, the fact that the Company has utilized certain 
services of Aon and its affiliates, but recognizing the arms’ length 
nature of such transactions, the absence of any managerial role 
or specific pecuniary interest of Mr. Flaherty in such matters, 
and the de minimis percentage such transactions represented 
in respect of the annual revenues and assets of each of those 
companies.

 z Mr. Hansen, the fact that while he was previously an executive 
officer of the Company (until his retirement on April 30, 2014), 
more than five years have lapsed since the termination of his 
employment relationship with the Company.

 — BOARD OF DIRECTORS AND ITS COMMITTEES

The  Board  of  Directors  and  its  committees  meet  regularly 
throughout the year, and may also hold special meetings and 
act by written consent from time to time. In 2019, the Board of 
Directors held four regularly scheduled meetings and two special 
meetings. During this time, our directors attended 100% of our 
Board of Directors meetings and meetings of the committees 
on which they served. The Company’s Corporate Governance 
Guidelines provide that the Company’s non-management directors 
shall hold annually at least two formal meetings independent from 
management. Our Lead Independent Director presides at these 
executive sessions of the Board of Directors.

Three standing committees have been convened to assist the 
Board of Directors with various functions: the Audit Committee, the 
Compensation and Stock Option Committee, and the Nominating 
and Corporate Governance Committee. Each committee operates 
pursuant to a formal charter that may be obtained, free of charge, 
at the Company’s website at www.muellerindustries.com, or by

structure in which Mr. Christopher serves as both Chief Executive

Standards of Conduct

 — STANDARDS OF CONDUCT

The Board of Directors has adopted various policies, including 
a comprehensive set of Corporate Governance Guidelines, by 
which the Company is governed. These policies are designed to 
promote sound corporate governance and prudent stewardship 
of the Company, both by the Board of Directors and management.

results, as determined by the Compensation and Stock Option 
Committee. The Company’s right of recoupment pursuant to this 
policy applies to incentive awards received during the three-year 
period preceding the date on which the Company is required 
to prepare the restatement, based on the determination of the 
Company’s independent registered public accounting firm.

Anti-Pledging Policy
The Corporate Governance Guidelines include amendments 
adopted in February 2020 that prohibit the future pledging of the 
Company’s common stock as security under any obligation by 
our directors and executive officers. 

Insider Trading and Anti-Hedging 
Policies
The Company maintains a policy which mandates compliance with 
insider trading laws and institutes safeguards to mitigate the risk 
of insider trading. Further, the Corporate Governance Guidelines 
prohibit any director, officer or employee of the Company from 
engaging in short sales, transactions in derivative securities 
(including put and call options), or other forms of hedging and 
monetization transactions, such as zero-cost collars, equity 
swaps, exchange funds and forward sale contracts, that allow 
the holder to limit or eliminate the risk of a decrease in the value 
of the Company’s securities.

Clawback Policy
Under the Corporate Governance Guidelines, if the Company 
is  required  to  restate  its  financial  results  due  to  material 
noncompliance with financial reporting requirements under the 
securities laws as a result of an executive’s (i.e., a President or Vice 
President level officer’s) willful, knowing or intentional misconduct 
or gross negligence (as determined by the Compensation and 
Stock Option Committee), the Company may take action to recoup 
from the executive all or any portion of an incentive award received 
by the executive, the amount of which had been determined in 
whole or in part upon specific performance targets relating to the 
restated financial results. In such an event, the Company shall be 
entitled to recoup up to the amount, if any, by which the incentive 
award actually received by the executive exceeded the payment 
that would have been received based on the restated financial 

Code of Business Conduct and Ethics
The  Company  has  adopted  a  Code  of  Business  Conduct 
and Ethics, which is designed to help officers, directors and 
employees resolve ethical issues in an increasingly complex 
business  environment.  The  Code  of  Business  Conduct  and 
Ethics is applicable to all of the Company’s officers, directors and 
employees, including the Company’s principal executive officer, 
principal financial officer, principal accounting officer or controller 
and other persons performing similar functions. The Code of 
Business Conduct and Ethics covers topics, including but not 
limited to, conflicts of interest, confidentiality of information and 
compliance with laws and regulations.

Director Responsibilities
It  is  the  duty  of  the  Board  of  Directors  to  serve  as  prudent 
fiduciaries for stockholders and to oversee the management of 
the Company’s business. Accordingly, the Corporate Governance 
Guidelines include specifications for director qualification and 
responsibility, attendance, access to officers and employees, 
compensation,  orientation,  continuing  education  and  self-
evaluation.

The  Company’s  policy  is  that  all  members  of  the  Board  of 
Directors attend annual meetings of stockholders, except where 
the failure to attend is due to unavoidable circumstances or 
conflicts discussed in advance with the Chairman of the Board. 
All members of the Board of Directors attended the Company’s 
2019 Annual Meeting of Stockholders.

Governance Guidelines and Code of Business Conduct and

Communication with the Board of Directors

 — COMMUNICATION WITH THE BOARD OF DIRECTORS

Any stockholder or interested party who wishes to communicate 
with the Board of Directors, or specific individual directors, including 
the non-management directors as a group, may do so by directing 
a written request addressed to such directors or director in care 
of the Chairman of the Nominating and Corporate Governance 
Committee, Mueller Industries, Inc., 150 Schilling Boulevard, Suite 
100, Collierville, Tennessee 38017. Communication(s) directed to 
the Chairman will be relayed to him, except to the extent that it is 

deemed unnecessary or inappropriate to do so pursuant to the 
procedures established by a majority of the independent directors. 
Communications directed to non-management directors will be 
relayed to the intended director except to the extent that doing 
so would be contrary to the instructions of the non-management 
directors. Any communication so withheld will nevertheless be 
made available to any non-management director who wishes to 
review it.

 — RELATED PARTY TRANSACTIONS

Related party transactions may present potential or actual conflicts 
of interest, and create the appearance that Company decisions 
are based on considerations other than the best interests of the 
Company and its stockholders. Management carefully reviews 
all proposed related party transactions (if any), other than routine 
banking transactions, to determine if the transaction is on terms 
comparable to those that could be obtained in an arms-length 

transaction with an unrelated third party. Management reports 
to the Audit Committee, and then to the Board of Directors 
on all proposed material related party transactions. Upon the 
presentation of a proposed related party transaction to the Audit 
Committee or the Board of Directors, the related party is excused 
from participation in discussion and voting on the matter.

 — CORPORATE SOCIAL RESPONSIBILITY 

The Company assesses and manages environmental, social 
and governance (“ESG”) considerations that may be material 
to the long-term sustainability of our business. Among other 
matters, we focus on such issues as workplace health and safety, 
environmental stewardship, business ethics and compliance, 
supply chain management and the development of human capital. 

We also focus outwardly on the communities in which we operate, 
including through a foundation that makes charitable contributions 
to  various  causes  and  organizations.  ESG-related  risks  and 
opportunities are integral to our strategic decision-making. Such 
matters are addressed by senior management and subject to the 
oversight of the Board of Directors and its committees.

To  further  align  the  Company’s  goal  of  aligning  directors’

directors recommending that they hold equity interests of the 
Company (including vested and unvested interests, provided that 
with respect to options, only vested options that are exercisable 
within  60  days  of  the  applicable  measurement  date  will  be 

counted) with a value equal to three times the annual cash director 
fee payable to each such director. All directors are expected to 
comply with the stock ownership guidelines within five years of 
being elected to the Board of Directors, and current directors 
should comply as soon as practicable. Director compliance with 
the stock ownership guidelines is monitored on an ongoing basis 
by the Company’s General Counsel.

APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
REPORT OF THE AUDIT COMMITTEE OF THE BOARD  OF DIRECTORS

 — REPORT OF THE AUDIT COMMITTEE OF THE BOARD  

OF DIRECTORS

The Audit Committee oversees the Company’s financial reporting 
process on behalf of the Board of Directors. Management has the 
primary responsibility for the financial statements and the reporting 
process, including the systems of internal controls. In fulfilling 
its oversight responsibilities, the Audit Committee reviewed the 
audited financial statements in the Annual Report on Form 10-K 
with management, including a discussion of the quality, not just 
the acceptability, of the accounting principles, the reasonableness 
of significant judgments and the clarity of disclosures in the 
financial statements.

The Audit Committee reviewed with the independent auditors, 
who are responsible for expressing an opinion on the conformity 
of those audited financial statements with generally accepted 
accounting principles, their judgments as to the quality, not just 
the acceptability, of the Company’s accounting principles and 
such other matters as are required to be discussed with the Audit 
Committee under Public Company Accounting Oversight Board’s 
(PCAOB) Auditing Standard No. 1301. In addition, the Audit 
Committee discussed with the independent auditors the auditors’ 
independence from management and the Company, including the 
matters in the written disclosures required by Public Company 
Accounting Oversight Board’s Rule 3526, and considered the 
compatibility of non-audit services provided by the independent 
auditors with the auditor’s independence.

The Audit Committee discussed with the Company’s internal 
and independent auditors the overall scope and plans for their 
respective audits. The Audit Committee meets with the internal 
and independent auditors, with and without management present, 
to discuss the results of their examinations, their evaluations of 
the Company’s internal controls, and the overall quality of the 
Company’s financial reporting.

In reliance on the reviews and discussions referred to above, the 
Audit Committee recommended to the Board of Directors (and 
the Board of Directors has approved) that the audited financial 
statements be included in the Company’s Annual Report on Form 
10-K for the year ended December 28, 2019 for filing with the 
SEC. The Audit Committee and the Board has re-appointed, 
subject to stockholder approval, Ernst & Young LLP, independent 
auditors, to audit the consolidated financial statements of the 
Company for the fiscal year ending December 26, 2020.

The Audit Committee is governed by a formal charter which can be 
accessed from the Company’s website at www.muellerindustries.
com,  or  may  be  requested  in  print  by  any  stockholder.  The 
members of the Audit Committee are considered independent 
because they satisfy the independence requirements for Board 
members prescribed by the NYSE listing standards and Rule 
10A-3 of the Exchange Act.

 z PROPOSAL 3
 z ADVISORY VOTE ON APPROVAL 

OF THE COMPENSATION OF THE 
COMPANY’S NAMED EXECUTIVE 
OFFICERS

In accordance with Section 14A of the Exchange Act, stockholders 
are being asked to vote on an advisory, non-binding basis, on 
the compensation of the Company’s named executive officers. 
Specifically,  the  following  resolution  will  be  submitted  for  a 
stockholder vote at the Annual Meeting, the approval of which 
will require the affirmative vote of a majority of the outstanding 
shares of the Company present in person or by proxy at the 
Annual Meeting and entitled to vote thereon:

“RESOLVED, that the stockholders of the Company 
approve, on an advisory basis, the compensation of 
the Company’s named executive officers listed in the 
2019 Summary Compensation Table included in the 
proxy statement for the 2020 Annual Meeting, as such 
compensation is disclosed pursuant to Item 402 of 
Regulation S-K in this proxy statement under the section 
titled “Compensation Discussion and Analysis,” as well 
as the compensation tables and other narrative executive 
compensation disclosures thereafter.”

Although the stockholder vote is not binding on either the Board 
of Directors or the Company, the views of stockholders on these 
matters are valued and will be taken into account in addressing 
future compensation policies and decisions.

The Company’s Compensation and Stock Option Committee 
is comprised of knowledgeable and experienced independent 
directors, who are committed to regular review and effective 
oversight  of  our  compensation  programs.  The  Company’s 
executive  compensation  program  is  grounded  in  a  pay  for 
performance philosophy, and accordingly, has been designed 
to  motivate  the  Company’s  key  employees  to  achieve  the 
Company’s strategic and financial goals, and to support the 
creation of long-term value for stockholders. Moreover, given 
the particularly competitive markets in which we operate and 
nature of our business, a principal goal underlying the Company’s 
long-term incentive compensation program specifically is the 
long-term retention and motivation of critical executives and 
business  leaders.  The  Company’s  success  depends  upon 
their leadership, judgment and experience, and as such, our 
compensation program is designed to promote their enduring 
commitment to the Company. We encourage stockholders to 
read the Executive Compensation section of this proxy statement, 
including the Compensation Discussion and Analysis (CD&A) 
and compensation tables, for a more detailed discussion of the 
Company’s compensation programs and policies, and how they 
are appropriate and effective in promoting growth, creating value, 
and retaining key members of our team.

 — EXECUTIVE SUMMARY

This Compensation Discussion and Analysis (“CD&A”) provides an overview of how our named executive officers were compensated 
in 2019, as well as how this compensation furthers our established compensation philosophy and objectives.

Our Named Executive Officers
The Company’s NEOs for fiscal year 2019 were:

GREGORY L. 
CHRISTOPHER
Chief Executive Officer 
& Chairman

JEFFREY A. MARTIN
Chief Financial Officer  
& Treasurer

NICHOLAS W. MOSS 
President – B&K LLC(1)

STEFFEN SIGLOCH
Chief Manufacturing  
Officer

GARY WESTERMEYER
President – Refrigeration

(1)  Effective, January 1, 2020, Mr. Moss assumed the title of President – New Business Development.

Our Compensation Philosophy and 
Guiding Principles
We believe in a pay for performance philosophy, such that a 
material portion of a named executive officer’s compensation 
is dependent upon both the short-term and long-term strategic 
and financial performance of the Company, considered in light 
of  general  economic  and  specific  Company,  industry,  and 
competitive  conditions.  For  2019,  we  continued  to  reward 
named  executive  officers  in  a  manner  consistent  with  this 
philosophy by setting annual incentive targets based on the 
Company’s achievement of certain levels of operating income. 
While also rooted in a pay for performance philosophy, our 

long-term equity incentive compensation focused primarily on 
promoting the retention of key executives and business leaders 
in our industry, where the competition for leadership talent is a 
foremost concern. Accordingly, we continued to grant equity 
awards, such that any long-term compensation opportunity will 
be directly tied to stock performance, and will only be received 
by key executives and business leaders who remain with and 
make  long-term  commitments  to  the  Company’s  success. 
The Compensation and Stock Option Committee (hereinafter 
referred  to  as  “the  Committee”  for  purposes  of  this  CD&A 
section) evaluates, on an annual basis, the overall structure 
and design of our program, and believes it has and continues 
to reflect the best balance of the Company’s priorities.

TRANSPARENCY 
AND  
SIMPLICITY  
OF DESIGN

We emphasize long-term 
stockholder value creation by 
utilizing performance-based 
restricted stock units and stock 
options to deliver long-term 
compensation incentives  
while minimizing risk-taking 
behaviors that could undermine 
long-term objectives.

Each executive has clear 
performance expectations 
and must contribute to  
the overall success of the 
Company, as opposed to 
solely objectives within 
 his or her primary  
area of responsibility.

The attraction and retention of 
key executives and business 
leaders is a core objective 
of our long-term incentive 
compensation program. In 
addition to performance-based 
criterion, our equity awards  
vest on longer time horizons  
to incentivize key executives  
to make longstanding 
commitments to the Company.

The three main elements of 
our compensation program 
— base salary, annual cash 
incentive compensation and  
long-term equity incentive 
compensation — reflects an 
appropriate blend of goals 
and are based on easily 
understood objectives.

Our Compensation Practices At a Glance

Our pay and equity programs are designed to align executives’ interests with those of our stockholders, and to motivate and retain 
critical leaders. Below is a snapshot of our compensation practices:

WHAT WE DO

WHAT WE DON’T DO

We maintain a fully independent Compensation and Stock 
Option Committee.

We do not provide for single trigger severance upon a 
change in control.

A higher percentage of our executives’ compensation is 
variable than fixed.

We do not permit gross-up payments to cover excise taxes 
or perquisites.

We utilize varying performance metrics under our short-
term and long-term incentive plans.

We do not permit the pledging or hedging of our common 
stock.

Our annual incentive program is based on earnings 
performance and capped for maximum payouts.

We do not support compensation programs or policies that 
reward material or excessive risk taking.

Our equity awards include extended vesting schedules and 
performance-based criteria.

We do not maintain any supplemental executive retirement 
plans.

We have a clawback policy applicable to all senior 
employees, including all President and Vice President level 
personnel.

2019 Say-on-Pay Vote and 
Stockholder Engagement
At our 2019 Annual Meeting, we held our annual non-binding 
stockholder  advisory  vote  on  executive  compensation. 
Approximately 73% of our shares voted (excluding abstentions 
and broker non-votes) were in favor of the compensation of our 
named executive officers as disclosed in the proxy statement 
for the 2019 Annual Meeting.

In response to the results of the 2019 say-on-pay vote, the 
Company’s management and Committee Chairman held in-
person  meetings  with  various  stockholders  to  discuss  the 
Company’s  compensation  practices  and  the  philosophies 
underlying  them.  Those  discussions  afforded  stockholders 
the opportunity to raise questions and concerns regarding 
the  executive  compensation  program  as  presented  in  last 
year’s proxy solicitation. Through productive and informative 
engagement with its stockholders, the Company learned that the 
manner in which the Company had historically communicated 

MUELLER INDUSTRIES ● 2020 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSIS
Determination of Executive Compensation

and  presented  its  executive  compensation  program  in  its 
proxy solicitations was unclear, and did not adequately convey 
the Company’s compensation philosophy, priorities and the 
market and strategic considerations that support them. One 
specific aspect of the compensation program for which this 
was  particularly  true  was  the  Company’s  long-term  equity 
incentive awards, and how the performance-based criterion 
underlying those equity awards were chosen to emphasize 
long-term strategic growth and to serve as a complement to 
the Company’s ambitious targets underlying its annual cash 
incentive program, in an effort to create a balanced and well-
rounded incentive structure.

As part of its robust response to the results of the 2019 say-
on-pay vote, the Company has determined that in 2020, the 
long-term equity incentive awards given to its operational 
business leaders will, for the first time, be tied to achievement 
of  the  ambitious  targets  set  forth  in  the  Company’s  2024 
Strategic  Growth  Plan.  These  awards  will  be  made  later 

in 2020 and discussed in next year’s proxy statement. We 
believe that this step will further align pay and performance, 
focus our operational leadership on long-term value creation, 
and be a strong motivating incentive and tool for retention.

Further, in response to feedback received from stockholders 
following the 2019 say-on-pay vote, the Company has not 
only endeavored this year to more clearly and fully present 
its compensation program, but to dramatically revamp the 
look, format and substance of this year’s proxy statement. 
Our goal in doing so was to provide a more useful, appealing 
and  granular  tool  to  assist  stockholders  in  evaluating  our 
compensation  program,  including  pay-for-performance 
alignment and whether it serves the vital strategic goal of 
attracting and  retaining key executives  in the competitive 
markets in which we participate.

The  Committee  will  consider  the  outcome  of  this  year’s 
stockholder advisory vote on executive compensation as it 
makes future compensation decisions.

 — DETERMINATION OF EXECUTIVE COMPENSATION

Guided  by  the  philosophy  and  design  outlined  above,  the 
Committee  determines  the  compensation  of  our  Chief 
Executive Officer. In turn, our Chief Executive Officer makes 
recommendations to the Committee regarding all components 
of our other NEOs’ compensation, including base salary, annual 
cash incentive compensation, and long-term equity incentive 
compensation.  The  Committee  considers  and  acts  upon 
those recommendations in setting the compensation of our 
other NEOs.

In making compensation decisions, the Committee relies on the 
members’ general knowledge of our industry, supplemented  
by  advice  from  our  Chief  Executive  Officer  based  on  his 
knowledge  of  our  industry  and  the  markets  in  which  we 
participate. From time to time, we conduct informal analyses 
of compensation practices and our Compensation and Stock 
Option Committee may review broad-based third-party surveys 
to obtain a general understanding of current compensation 
practices.

In determining compensation, we generally do not rely upon 
hierarchical or seniority-based levels or guidelines, nor did the 
Committee formally benchmark executive compensation (or any 
component thereof) against any particular peer group. Instead, 
we  utilize  a  more  flexible  approach  that  allows  us  to  adapt 
components and levels of compensation to motivate and reward 
individual executives within the context of our broader strategic 
and financial goals. This requires that we consider subjective 
factors including, but not limited to the following:

 z The nature of the executive’s position;

 z The performance record of the executive, combined with the 
value of the executive’s skills and capabilities in supporting the 
long-term performance of the Company;

 z The Company’s overall operational and financial performance; and

 z Whether each executive’s total compensation potential and 
structure is sufficient to ensure the retention of the executive 
officer when considering the compensation potential that may 
be available elsewhere. 

The Committee has chosen incentive operating income targets 
as the metric to measure performance for each named executive 
officer. The compensation of Messrs. Christopher and Martin is 
based upon their oversight of and responsibility for the entire 
Company. Accordingly, their compensation levels are reflective 
of the scope and breadth of their management responsibility, 
and the performance of the Company on a consolidated basis. 
For Messrs. Sigloch, Moss, and Westermeyer, a portion of 
their compensation is based upon the performance of specific 
business lines within their purviews. Notwithstanding, a portion 
of their compensation is still based upon consolidated Company 
performance to discourage parochialism and align their interests 
with those of our stockholders.

Elements of Compensation

 — ELEMENTS OF COMPENSATION

As outlined below, our compensation program for our NEOs is 
comprised of three primary elements: (i) base salary and traditional 
benefits, (ii) annual incentive compensation, and (iii) long-term 
equity incentive compensation. Each element plays an integral role 

in our overall compensation strategy. Moreover, the Committee 
has approved certain executive perquisites and post-employment 
change-in-control compensation to our NEOs for purposes of 
motivating them and retaining their services.

Annual Incentive Compensation

Base salaries paid to our NEOs are set forth in the “Summary 
Compensation Table for 2019.” Base salary adjustments are 
determined by making reasoned subjective determinations about 
current economic conditions such as general wage inflation as 
well as the executive’s qualifications, experience, responsibilities, 
and past performance. In addition to base salaries, we provide 
traditional  benefits  such  as  group  health,  disability,  and  life 
insurance benefits, as well as matching contributions to our 
401(k) plan.

Each of our NEOs received annual incentive compensation for 
2019, based upon the actual performance of the Company and, 
for Messrs. Moss, Sigloch and Westermeyer, the performance of 
the business lines which they oversee, relative to the performance 
targets (as described below) established by the Committee on 
February 4, 2019. The table below shows the target annual 
incentive award for each of our NEOs.

For 2019, the amount of incentive compensation payable to each of our named executive officers was calculated as follows:

Long-Term Equity Incentive Compensation 
Program

OVERVIEW

Our long-term equity-based incentive compensation program 
serves three goals:

1.  Aligning our NEOs’ financial interests with the interests of our 

stockholders;

2.  Retaining the services of talented and seasoned executives, 
and motivating them to make deep, long-term commitments 
to the Company; and

3.  Rewarding our NEOs for advancing our long-term financial 

success and increasing stockholder value.

The Committee has made the retention of executives and key 
employees a particular focus of the long-term equity incentive 
compensation program in recent years.

The  Committee  has  decided  that  the  best  way  to  meet  the 
objectives of our long-term incentive program is to award a 
combination of time-based restricted stock and performance-
based restricted stock, allocated as shown below. To promote 
our goal of executive and key employee retention, time-based 
restricted stock awards vest over the course of a five-year period, 
on one of two vesting schedules: (i) 30% after three years; 30% 
after four years; and 40% after five years, or (ii) 100% cliff vesting  
after  five  years.  Performance-based  restricted  stock  is  also 
awarded,  and  provided  performance  criteria  are  met  over  a 
five year performance period, cliff vests 100% after approximately 
four and a half years. Unvested shares are generally forfeited if the 
recipient leaves the Company employ prior to the vesting date.

The Committee believes that the extended and cliff vesting schedules, and performance criteria described below will motivate our 
NEOs and key employees to remain with the Company and make long-term contributions to stockholder value generation.

FIVE-YEAR VESTING SCHEDULE FOR TIME-BASED AND 
PERFORMANCE-BASED RESTRICTED STOCK

To  foster  retention,  the  2019  time-based  restricted  stock 
awards vest over the course of a five year period (i.e., either 
(i) 30% after three years; 30% after four years; and 40% after 
five years, or (ii) 100% after five years). For performance-based 
awards, the performance period is five years, and vesting occurs 
approximately four and a half years from the grant date. No portion 
of the equity awards granted to our executives or employees 
vest in less than three years. The Committee elected to use a 

long-term vesting schedule to promote executive retention in our 
competitive industry and to incentivize performance. However, 
given the importance of long-term equity incentive awards in our 
compensation program, the Committee provided for accelerated 
vesting in the event of death, disability or a change in control 
(as explained in more detail in the “2019 Grant of Plan Based 
Awards Table”). The Committee believes that accelerated vesting 
would be appropriate in those circumstances to encourage our 
executives to focus on the potential benefits of a change in control 
transaction for our stockholders without harboring concerns for 
their financial security.

PERFORMANCE CRITERIA FOR PERFORMANCE-BASED 
RESTRICTED STOCK

A portion of the long-term equity awards granted to our NEOs 
and  key  employees  are  performance-based,  and  vesting  is 
contingent upon the Company’s performance on two metrics: 
total stockholder return (TSR) and diluted earnings per share 
(EPS). Using these two metrics ensures that performance-based 
awards will not vest unless the Company achieves specified 
growth targets over a five-year performance period, which for 
the 2019 grants, was December 30, 2018 to December 30, 2023. 
For this purpose, total stockholder return will be determined by 
dividing (i) an amount equal to the 30-day trailing average closing 
price of a share of stock at the end of the performance period, 
minus $23.44 (the 30-day trailing average closing price of a 
share of stock as of December 30, 2018), plus the value of any 
dividends and distributions paid during the performance period, 
by (ii) $23.44, and multiplying such amount by 100.

To be clear, the growth targets established for our long-term 
equity incentive awards (i.e., a 3.5% compounded annual growth 
rate in TSR or EPS) are just one of a number of different, yet 
complementary performance metrics utilized by the Company 
in its efforts to design an overall compensation program that 
is appropriately balanced and furthers its underlying aims. For 
example, the Company’s performance-based compensation 
program also incorporates the ambitious short and long-term 
operating  targets  that  underlie  the  Company’s  annual  cash 
incentive compensation program and long-term aspirations for 
strategic growth. Indeed, and as previously noted, the Company 
has determined that in 2020, the long-term equity incentive 
awards given to its operational business leaders will be tied to 
achievement of the ambitious targets set forth in the Company’s 
2024 Strategic Growth Plan.

The Company has traditionally maintained, and will continue to 
maintain lofty expectations and goals with respect to stockholder 
value creation. Nevertheless, given the primary retention aim of the 
long-term equity incentive compensation program, the Committee 
has concluded that the performance-based criterion for the equity 
awards granted to our NEOs are appropriate in the context of our 
well-balanced overall executive compensation program.

COMPENSATION DISCUSSION AND ANALYSIS
Elements of Compensation

TIMING OF LONG-TERM EQUITY AWARD GRANTS

Long-term equity incentive awards to our Chief Executive Officer 
are granted annually, typically in July, based on the determinations 
of the Committee. Long-term equity incentive awards to our other 
NEOs have traditionally been granted by the Committee (upon our 
Chief Executive Officer’s recommendation) following the release of 
the Company’s second quarter and six-month operating results. 
In 2019, the NEOs received their annual grants in August 2019. 

In granting long-term equity awards to our NEOs, the Committee 
applied  no  set  formula  for  allocating  awards,  and  instead 
made reasoned, subjective determinations based upon their 
performance, the importance of retaining their services, and 
their role in helping us achieve our long-term goals. In 2019, 
we granted shares of restricted stock to our NEOs covering an 
aggregate of 217,000 shares.

In addition to Mr. Christopher’s annual grant, the Committee 
determined to grant him a special performance-based restricted 
stock award (conditioned on achievement of the performance-
based criteria discussed above) in July 2019, in recognition of his 
outstanding service, leadership and commitment to the future and 
well-being of the Company.

Perquisites

We offer perquisites to our NEOs, which we view as an added 
element of our executive compensation program designed not 
only to attract, retain and reward our NEOs, but also to facilitate 
their performance of their duties on behalf of the Company. 
The perquisites we provided to our NEOs in fiscal year 2019 
are set forth in the “Summary Compensation Table for 2019”, 
and included, among others, estate and tax planning, personal 
use of our Company airplane, and reimbursement of the income 
tax liabilities associated with certain perquisites. Estate and tax 
planning is provided to certain NEOs to complement our various 
compensation elements for the purpose of ensuring the NEOs 
understand the complexity of the long-term equity incentives 
and are thereby able to maximize the value of such benefits. We 
maintain a Company-owned airplane primarily to provide efficient 
transportation for executives, employees and customers to our 
geographically dispersed operations. From time to time, when 
our plane is not being used for business purposes, we allow 
certain NEOs to use the plane for personal travel. We have also 
provided executive physicals as a risk management tool and to 
ensure our NEOs are mindful of their personal health. Certain 
club memberships are provided, and serve the primary aim of 
facilitating networking with business clients.

COMPENSATION DISCUSSION AND ANALYSIS
Compensation Risk Management

 — COMPENSATION RISK MANAGEMENT

In connection with its continued appraisal of our compensation 
program, management, with oversight from the Committee, 
reviews our compensation policies and practices, and the overall 
compensation program with respect to our risk management 

practices and any potential risk-taking incentives. This assessment 
includes a review of the primary elements of our compensation in 
light of potential risks:

COMPENSATION PROGRAM RISK CONSIDERATIONS

Pay Mix

 z Compensation program includes an appropriately balanced mix of short and long-term 

incentives, which mitigates the risk of undue focus on short-term targets while rewarding 
performance in areas that are key to our long-term success.

 z Base salaries are set at competitive levels to promote stability and give executives an element 

of compensation that is not at risk.

Performance Metrics and Goals

 z Distinct performance metrics are used in both our short-term and long-term incentive plans. 

 z Our annual incentive compensation program includes a payout scale (and cap) reflective of a 

pay for performance philosophy.

Long-term Incentives

 z Our long-term equity incentive program is designed to retain key executives and business 

leaders and to align their interests with those of our stockholders.

As previously detailed (see page 17), the Company has adopted a 
series of policies, including bans on pledging and hedging, and a 
clawback policy, to further mitigate risk taking behaviors. Beyond 
our Company clawback policy, which applies to all President 
and Vice President-level executives, our Chief Executive Officer 
and Chief Financial Officer are subject to clawback provisions 
under the Sarbanes Oxley Act of 2002. For these reasons, we 
believe that our compensation policies and practices are not likely 
to have a material adverse effect on the Company.

Tax Considerations
Section 162(m) of the Internal Revenue Code (the “Code”) generally 
disallows a tax deduction to public companies for compensation 
in  excess  of  $1,000,000  paid  to  certain  executive  officers, 
subject historically to an exception for qualifying “performance-
based compensation.” The Tax Cuts and Jobs Act, enacted on 
December 22, 2017, substantially modified Section 162(m) of 
the Code and, among other things, eliminated the performance-
based exception to the $1,000,000 deduction limit effective as of 
January 1, 2018. As a result, as of 2018, compensation paid to 
certain executive officers in excess of $1,000,000 is nondeductible, 
whether or not it is performance-based. In addition, beginning 
in 2018, the executive officers subject to Section 162(m) of the 
Code (the “Covered Employees”) will include any individual who 

served as the Chief Executive Officer and Chief Financial Officer at 
any time during the taxable year and the three other most highly 
compensated officers (other than the Chief Executive Officer and 
Chief Financial Officer) for the taxable year, and once an individual 
becomes a Covered Employee for any taxable year beginning 
after December 31, 2016, that individual will remain a Covered 
Employee for all future years, including following any termination 
of employment.

The Tax Cuts and Jobs Act includes a transition rule under which 
the changes to Section 162(m) of the Code described above 
will not apply to compensation payable pursuant to a written 
binding contract that was in effect on November 2, 2017 and is 
not materially modified after that date. To the extent applicable 
to our existing contracts and awards, we may avail ourselves 
of  this  transition  rule.  However,  because  of  uncertainties  as 
to the application and interpretation of the transition rule, no 
assurances can be given at this time that our existing contracts 
and awards, even if in place on November 2, 2017, will meet 
the requirements of the transition rule. Moreover, to maintain 
flexibility in compensating executive officers in a manner designed 
to promote varying corporate goals in the best interest of the 
company, we do not limit our actions with respect to executive 
compensation to preserve deductibility under Section 162(m) of 
the Code if we determine that doing so is in the best interests of 
the Company and its stockholders.

Pay Ratio
In 2019, the total compensation of Mr. Christopher, our Chief 
Executive Officer, was $8,064,706, as reported in the “Summary 
Compensation  Table  for  2019.”  Based  on  the  methodology 
described below, we determined that the median employee in 
terms of total 2019 compensation of all of our employees (other 
than Mr. Christopher) received an estimated $36,709 in total 
compensation for 2019. Therefore, the estimated ratio of 2019 
total compensation of Mr. Christopher to the median employee 
was 220:1.

In general, we offer employees base salary, company retirement 
plan contributions, the opportunity to receive incentive awards 
for performance, and other benefits. In accordance with SEC 
rules,  the  median  employee  compensation  provided  above 
reflects Company retirement plan contributions, incentive awards 
for 2019 performance and other benefits, but does not reflect 
benefits relating to group life or health plans generally available 
to all salaried employees.

To determine median  employee compensation, we took the 
following steps:

 z We identified our employee population as of December 28, 
2019, which consisted of approximately 4,964 employees.

 z For each employee (other than Mr. Christopher), we determined 
the sum of his or her base salary for 2019, and incentive awards 
for 2019. Comparing the sums, we identified an employee 
whose compensation best reflects the Company employees’ 
median  2019  compensation,  taking  into  account  whether 
their  compensation  likely  would  reflect  median  employee 
compensation in future years.

 z In  accordance  with  SEC  rules,  we  then  determined  that 
employee’s 2019 total compensation was $36,709 using the 
approach required by the SEC when calculating our named 
executive officers’ compensation, as reported in the Summary 
Compensation Table.

(1)  Represents annual cash incentive awards that could have been earned based on performance in 2019. These columns show awards that were possible 
at the threshold, target and maximum levels of performance for each NEO in 2019, determined by multiplying each named executive officer’s actual base 
salary paid during 2019, by the named executive officer’s incentive grade level factor, and then by a performance factor of 40% for the threshold level 
(for  80%  achievement  of  the  applicable  performance  criteria),  100%  for  the  target  level  (for  100%  achievement  of  the  applicable  performance  criteria), 
capped at 200% (or, in the case of Mr. Westermeyer, 150%) for the maximum level (for 120% achievement of the applicable performance criteria).

(2)  Shares of performance-based restricted stock will vest 100% on February 28, 2024, conditioned upon the Company’s achievement of a 3.5% compounded 
annual growth rate in total shareholder return or diluted earnings per share over the reference period (December 30, 2018 to the last day of the 2023 
fiscal year) and are subject to earlier vesting in connection with a change in control or a termination of employment due to death, disability or a qualifying 
retirement  (subject,  in  the  case  of  a  qualifying  retirement,  to  achievement  of  the  performance  criteria,  measured  through  the  last  day  of  the  fiscal  year 
preceding the year in which such qualifying retirement occurs). Amounts reported represent the target (which also represents the threshold and maximum) 
number of performance-based shares of restricted stock that have the potential to vest pursuant to the foregoing vesting schedule.

(3)  Shares of time-based restricted stock will vest 30% on each of July 30, 2022 and July 30, 2023, and 40% on July 30, 2024 (or in the case of Mr. Westermeyer, 
100% on July 30, 2024). They are subject to earlier vesting in connection with a change in control, or a termination of employment due to death or disability. 
Mr. Christopher’s grants also vest upon a termination of employment without cause or resignation for good reason. 

Narrative Disclosure to Summary 
Compensation Table and Grant of 
Plan Based Awards Table

Employment Agreement with Mr. Christopher

On  March  15,  2018,  we  entered  into  an  indefinite  term 
employment agreement (the “Employment Agreement”) with 
Mr. Christopher, pursuant to which he will continue to serve as 
the Company’s Chief Executive Officer, reporting directly to the 
Board. The Employment Agreement replaced Mr. Christopher’s 
prior employment agreement and, in so doing, eliminated the 
“single-trigger” severance to which Mr. Christopher would have 
been entitled upon the occurrence of a change in control of 
the Company.

The Employment Agreement provides that Mr. Christopher will 
receive a base salary of not less than $1,100,000 per year and will 
be eligible to receive an annual bonus award. For each fiscal year, 

Mr. Christopher’s target annual bonus will be 125% of his base 
salary upon achievement of target performance levels, and he will 
be eligible for a maximum annual bonus of 250% of base salary 
when performance equals or exceeds 125% of the applicable 
performance objectives. The actual annual bonus payable to 
Mr. Christopher will be based upon the actual level of achievement 
of annual Company and individual performance objectives for the 
applicable year, as determined by the Committee. In addition, 
during the term of Mr. Christopher’s employment, the Company 
will maintain a term life insurance policy for him with a face value 
of at least $5 million, and Mr. Christopher will have the right to 
name the beneficiary of such term life insurance policy.

In the event that Mr. Christopher’s employment is terminated for 
any reason (other than by the Company for “cause” (as defined 
in the Employment Agreement)), he will, subject to his execution 
of a general release in favor of the Company and his continued 
compliance with certain restrictive covenants (the “Conditions”), 
be entitled to receive the following: (i) any accrued but unpaid 
compensation and benefits; (ii) any unpaid annual bonus with 

36 MUELLER INDUSTRIES ● 2020 PROXY STATEMENT

EXECUTIVE COMPENSATION TABLES
2019 Grants of Plan Based Awards Table

respect to the previously completed fiscal year; (iii) subject to 
achievement  of  the  applicable  performance  objectives  for 
the fiscal year in which the termination occurs, payment of a 
prorated annual bonus for such fiscal year; and (iv) continued 
medical, dental and hospitalization coverage (or payment in lieu 
of coverage if coverage is not permitted by applicable law or 
the terms of the applicable plan) for Mr. Christopher, his spouse 
and covered dependents until the latest of Mr. Christopher’s 70th 
birthday, his spouse’s 70th birthday, and the 3rd anniversary of 
such termination.

Additionally, if Mr. Christopher’s employment is terminated by 
the Company without “cause” or by Mr. Christopher for “good 
reason” (as defined in the Employment Agreement), and there 
has not been a “change in control” (as defined in the Employment 
Agreement) in the past 24 months, Mr. Christopher will, subject 
to the Conditions, be entitled to (i) continued payment of his 
base salary for 36 months; and (ii) an amount equal to 3 times 
Mr. Christopher’s target annual bonus in respect of the fiscal year 
in which such termination occurs (or prior fiscal year, if greater), 
such amount to be paid in equal installments over the 3 -year 
period following such termination at the same time such amounts 
would otherwise have been paid had no termination occurred. 
If Mr. Christopher’s employment is terminated by the Company 
without “cause” or by Mr. Christopher for “good reason” within 
24 months of a “change in control,” Mr. Christopher will, subject 
to the Conditions, be entitled to (i) payment of his base salary for 
36 months in a lump sum on the first regularly-scheduled payroll 
date following the 60th day following such termination; and (ii) an 
amount equal to 3 times Mr. Christopher’s target annual bonus 
in respect of the fiscal year in which such termination occurs 
(or prior fiscal year, if greater), paid in a lump sum on the first 
regularly-scheduled payroll date following the 60th day following 
such termination. The Employment Agreement does not provide 
for any “single-trigger” severance payments or benefits.

The Employment Agreement does not provide any gross-up or tax 
assistance on the severance benefits. Instead, the Employment 
Agreement contains a “modified cutback” provision, which would 
act to reduce the benefits payable to Mr. Christopher to the extent 
necessary to avoid a “golden parachute excise tax,” but only if 
such reduction would result in Mr. Christopher retaining a larger 
after-tax amount.

Mr. Christopher is subject to certain restrictive covenants during 
the term of his employment and thereafter, including customary 
non-compete restrictions that apply for one year post-termination 
and  customary  non-solicitation  restrictions  with  respect  to 
current and prospective employees that apply for one year post-
termination. In addition, during the term of his employment and for 
one year thereafter, Mr. Christopher is prohibited from contacting 
any customer or prospective customer of the Company, or any 
representative of the same, for the purpose of providing any 
service or product competitive with any service or product sold 
or provided by the Company.

Change in Control Agreements with Mssrs. 
Martin, Moss and Sigloch

On July 26, 2016, the Company entered into change in control 
agreements with certain key members of the management team, 
including Messrs. Martin, Moss and Sigloch. Pursuant to those 
agreements, if, upon or within two years following a “change 
in control”, the executive’s employment is terminated by the 
Company without “cause” (other than on account of death or 
Disability), or by the executive for “good reason”, subject to 
execution of a general release of claims, the executive will be 
entitled to: (i) an amount equal to two times the executive’s base 
salary (as in effect immediately prior to the change in control or, 
if greater, the date of such termination); and (ii) an amount equal 
to two times the average annual bonus paid to the executive 
(including,  for  this  purpose  only,  any  amounts  deferred)  in 
respect of the three calendar years immediately preceding the 
calendar year in which the change in control occurs (or the three 
calendar years immediately preceding the calendar year of such 
termination, if greater). The terms “change in control” and “cause” 
are defined in the 2014 Incentive Plan and the term “good reason” 
is defined in each executive’s change in control agreement. The 
agreements also provide that for two years following termination 
under the circumstances described above, each of Messrs. 
Martin, Moss and Sigloch will receive (subject to the executive’s 
election of COBRA continuation coverage under the Company’s 
group health plan) continued coverage under the Company’s 
group health plan at the Company’s cost (or at the direction of 
the Company, reimbursement for COBRA premiums) for two years 
following such termination. We are not party to an employment or 
change in control agreement with Mr. Westermeyer.

2019 and 2014 Incentive Plans

In  2019,  we  maintained  the  2019  Incentive  Plan  and  2014 
Incentive Plan (together, the “Plans”), which were approved by 
our stockholders at our Annual Meetings held in May 2019 and 
May 2014 respectively. The Committee administers the Plans 
and is authorized to, among other things, designate participants, 
grant  awards,  including  cash-based  awards  that  historically 
were intended to qualify as performance-based compensation 
for purposes of Section 162(m) of the Internal Revenue Code, 
determine the number of shares of Common Stock to be covered 
by awards and determine the terms and conditions of any awards, 
and construe and interpret the Plans and award agreements 
issued  pursuant  thereto.  The  2014  Incentive  Plan  reserved 
1,500,000  shares of our Common Stock for issuance, subject 
to adjustment in the event of any change in the outstanding 
Common Stock or the capital structure of the Company or any 
other  similar  corporate  transaction  or  event.  The  2019  Plan 
reserved 2,000,000 shares of our Common Stock for issuance, 
subject to adjustments under similar circumstances. A previously 
authorized 2009 Incentive Plan expired in February 2019. No 
remaining shares are authorized to be issued under that 2009 
Incentive Plan.

years post-termination. Also includes the value of a pro-rata bonus for the year of termination, determined based on actual performance, which is payable upon 
a termination for any reason (other than by the Company for cause). The pro-rata bonus amount listed represents Mr. Christopher’s 2019 bonus paid pursuant to 
our 2019 annual incentive program. If Mr. Christopher is terminated without cause or resigns for good reason during the 24 month period following a change in 
control, the amounts will be paid in a lump sum within 60 days following termination.
Includes the value of a pro-rata bonus for the year of termination. The pro-rata bonus amount listed represents Mr. Christopher’s 2019 bonus paid pursuant to our 
2019 annual incentive program.
Includes the value of continued participation in the Company’s benefit plans following termination of employment until Mr. Christopher’s spouse’s 70th birthday, 
which Mr. Christopher is entitled to following a termination for any reason (other than by the Company for cause).
Includes the value of accelerated vesting of unvested shares of restricted stock as of December 28, 2019, based on a per share value of $31.75. Unvested shares 
of restricted stock granted to NEOs will vest automatically in connection with a termination due to death or disability or a change in control. Mr. Christopher is also 
entitled to accelerated vesting of certain of his awards upon an involuntary termination without cause or a resignation for good reason. Payments to which named 
executive officers are entitled upon the accelerated vesting of restricted stock included payments associated with declared dividends and interest.
Includes the value of: (i) two times the executive’s base salary as in effect on December 28, 2019; (ii) two times the average annual bonus actually paid to the 
executive for the three calendar years preceding December 28, 2019; and (iii) the value of continued participation in Company’s group health plan for a period of 
two years. All amounts are payable on an involuntary termination without cause or upon a resignation by the executive for good reason that occurs upon or within 
two years following a change in control. Messrs. Martin, Moss, and Sigloch are not entitled to any amounts in connection with such an involuntary termination that 
occurs outside of this two-year, post-change in control window.

(1)  This information is based on a Schedule 13G/A filed by BlackRock, Inc. with the Securities and Exchange Commission (“SEC”) on February 4, 2020. 
BlackRock filed this Schedule 13G/A on its own behalf and on behalf of certain of its subsidiaries. The Schedule 13G/A reported that BlackRock has 
sole voting and dispositive power with respect to 8,366,446 and 8,493,358, respectively, of the shares shown. The Schedule 13G/A also reported that 
BlackRock Fund Advisors owned 5% or greater of the security class being reported on the Schedule 13G/A.

(2)  The percent of class shown was based on the shares of Common Stock reported on the Schedule 13G/A and the total number of shares outstanding as 
of December 28, 2019. The difference in the total number of shares outstanding on December 28, 2019 and March 20, 2020 does not materially affect 
the percentage of ownership of the class.

(3)  This information is based on a Schedule 13D/A filed by GAMCO Investors Inc. (“GBL”) and certain of its affiliates (collectively, the “Gabelli Reporters”) on 
October 27, 2016. The Schedule 13D/A reported that GAMCO Asset Management, Inc. (“GAMCO”) beneficially owns 4,144,650 of the shares reported; 
Gabelli  Funds,  LLC  (“Gabelli  Funds”)  beneficially  owns  2,142,100  of  the  shares  reported;  GGCP,  Inc.  beneficially  owns  15,000  of  shares  reported;  
Mario J. Gabelli (“Gabelli”) beneficially owns 73,500 of the shares reported; Gabelli Foundation, Inc. beneficially owns 8,000 of the shares reported; MJG 
Associates, Inc. beneficially owns 1,000 of the shares reported; Associated Capital Group, Inc. beneficially owns 4,000 of the shares reported; and Gabelli 
Securities, Inc. beneficially owns 500 of the shares reported. In addition, the Schedule 13D/A reported that each Gabelli Reporter (and certain executives, 
directors and other related persons as disclosed on the Schedule 13D/A) has the sole power to vote or direct the vote and sole power to dispose or to 
direct the disposition of the Common Stock reported for it, either for its own benefit or for the benefit of its investment clients or its partners, as the case 
may be, except that (i) GAMCO does not have authority to vote 246,176 of the reported shares, (ii) Gabelli Funds, a wholly-owned subsidiary of GBL, has 
sole dispositive and voting power with respect to the shares of the Company held by certain funds (the “Funds”) for which it provides advisory services, so 
long as the aggregate voting interest of all joint filers does not exceed 25% of their total voting interest in the Company and, in that event, the Proxy Voting 
Committee of each Fund shall respectively vote that Fund’s shares, (iii) at any time, the Proxy Voting Committee of each such Fund may take and exercise 
in its sole discretion the entire voting power with respect to the shares held by such fund under special circumstances such as regulatory considerations,

THE ANNUAL MEETING

When  a  proxy  card  is  returned  properly  signed,  the  shares 
represented  thereby  will  be  voted  in  accordance  with  the 
stockholder’s directions appearing on the card. If the proxy card 
is signed and returned without directions, the shares will be 
voted for the nominees named herein and in accordance with 
the recommendations of the Company’s Board of Directors as set 
forth herein. A stockholder giving a proxy may revoke it at any time 
before it is voted at the Annual Meeting by giving written notice to 
the secretary of the Annual Meeting or by casting a ballot at the 
Annual Meeting. Votes cast by proxy or in person at the Annual 
Meeting will be tabulated by election inspectors appointed for 
the Annual Meeting. The election inspectors will also determine 
whether a quorum is present. The holders of a majority of the 
shares of common stock, $.01 par value per share (“Common 
Stock”), outstanding and entitled to vote who are present either 
in person or represented by proxy will constitute a quorum for 
the Annual Meeting.

The cost of soliciting proxies will be borne by the Company. In 
addition to solicitation by mail, directors, officers and employees 
of the Company may solicit proxies by telephone or otherwise. 
The Company will reimburse brokers or other persons holding 
stock in their names or in the names of their nominees for their 
charges and expenses in forwarding proxies and proxy material 
to the beneficial owners of such stock.

We are providing you with these proxy materials in connection 
with  the  solicitation  by  the  Board  of  Directors  of  Mueller 
Industries, Inc. (the “Company”) of proxies for our 2020 Annual

our corporate headquarters located at 150 Schilling Boulevard,

We intend to hold our Annual Meeting in person. However, we are 
actively monitoring the coronavirus (COVID-19); we are sensitive 
to the public health and travel concerns our shareholders may 
have and the protocols that federal, state, and local governments 
may impose. In the event it is not possible or advisable to hold 
our  Annual  Meeting  in  person,  we  will  announce  alternative 
arrangements for the meeting as promptly as practicable, which 
may include holding the meeting solely by means of remote 
communication. Please monitor our Annual Meeting website at 
www.muellerindustries.com for updated information. If you are 
planning to attend our meeting, please check the website one 
week prior to the meeting date. As always, we encourage you to 
vote your shares prior to the Annual Meeting.

This  Proxy  Statement,  together  with  the  Company’s  Annual

At  the  close  of  business  on  the  Record  Date,  there  were 
56,754,990 shares of Common Stock outstanding, which are 
the only shares entitled to be voted at the Annual Meeting. Each 
share of Common Stock is entitled to one vote. Only stockholders 
of record at the close of business on the Record Date will be 
entitled to notice of, and to vote at, the Annual Meeting. The 
Company’s Restated Certificate of Incorporation and Amended 
and Restated By-laws (“Bylaws”) do not provide for cumulative 
voting for the election of directors.

“Special Dividend”) consisting of $3.00 in cash and $5.00 in 
principal amount of the Company’s 6% Subordinated Debentures 
due 2027 (the “Debentures”) for each share of Common Stock 

outstanding as of the close of business on February 28, 2017. 
In connection with the Special Dividend, in accordance with the 
Company’s outstanding stock option plans and agreements, 
the  Company  adjusted  the  shares  subject  to  and  the  per 
share exercise price with respect to outstanding options. This 
adjustment resulted in an increase in the number of shares 
subject  to  each  outstanding  option  and  an  adjustment  to 
the option purchase price designed to maintain the option 
holders’  intrinsic  value  following  issuance  of  the  Special 
Dividend.  References  in  this  Proxy  Statement  to  beneficial 
stock ownership or outstanding options for periods following 
March 9, 2017 reflect the equitable adjustment made to options

“Householding.” Please note, if you do not respond, Householding 
will start 60 days after the mailing of this notice. We will allow 
Householding  only  upon  certain  conditions.  Some  of  those 
conditions are:

 z You agree to or do not object to the Householding of your 

materials,

 z You have the same last name and exact address as another 

investor(s).

If these conditions are met, and SEC regulations allow, your 
household will receive a single copy of annual reports, proxy 
statements, prospectuses and other disclosure documents.

You may revoke a prior Householding consent at any time by 
contacting Broadridge, either by calling toll-free at (800) 542-1061, 
or  by  writing  to  Broadridge,  Householding  Department, 
51 Mercedes Way, Edgewood, New York, 11717. We will remove 
you from the Householding program within 30 days of receipt of 
your response, following which you will receive an individual copy

BUSINESS

Introduction

Mueller Industries, Inc. (the Company) is a leading manufacturer of copper, brass, aluminum, and plastic products.  The range of 
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 tube and fittings; refrigeration valves and fittings; compressed gas valves; 
fabricated tubular products; pressure vessels; steel nipples; and insulated flexible duct systems.  We also resell 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.

Each of our 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 “Note 3 – Segment Information” in the 
Notes to Consolidated Financial Statements, which is incorporated herein by reference.

New  housing  starts  and  commercial  construction  are  important  determinants  of  our  sales  to  the  heating,  ventilation,  and  air-
conditioning (HVAC), 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.

Piping Systems Segment

The  Piping  Systems  segment  is  composed  of  Domestic  Piping  Systems  Group,  Great  Lakes  Copper  (Great  Lakes),    Pexcor 
Manufacturing Company and Heatlink Group Inc. (collectively, Heatlink Group), Die-Mold Tool Limited (Die-Mold), European 
Operations, Trading Group, and Jungwoo Metal Ind. Co., LTD (Jungwoo-Mueller).  

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.  Our copper tube ranges in size from 1/8 inch to 8 1/8 inch diameter 
and is sold in various straight lengths and coils.  We are a market leader in the air-conditioning and refrigeration service tube 
markets and we also supply a variety of water tube in straight lengths and coils used for plumbing applications in virtually every 
type of construction project.  Our copper fittings, line sets, and related components are produced for the plumbing and heating 
industry to be used in water distribution systems, heating systems, air-conditioning, and refrigeration applications, and drainage, 
waste, and vent systems.  

Great Lakes 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 manufactures copper tube in the United Kingdom, which is sold 
throughout Europe.  The Trading Group manufactures steel pipe nipples and resells brass and plastic plumbing valves, malleable 
iron fittings, faucets, and plumbing specialty products to plumbing wholesalers, distributors to the manufactured housing and 
recreational  vehicle  industries,  and  building  materials  retailers  in  North America.    Jungwoo-Mueller,  our  South  Korean  joint 
venture, manufactures copper-based joining products that are sold worldwide.

We acquired Great Lakes on July 31, 2015, a 60 percent equity interest in Jungwoo-Mueller on April 26, 2016, Heatlink Group 
on May 31, 2017, and Die-Mold on March 31, 2018.  These acquisitions complement our existing copper tube, line sets, copper 
fittings, and plastics businesses in the Piping Systems segment.

We disposed of Jiangsu Mueller-Xingrong Copper Industries Limited (Mueller-Xingrong), the Company’s Chinese joint venture, 
on June 21, 2017.  This business manufactured engineered copper tube primarily for air-conditioning applications in China.

3

 
The 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).  
It markets primarily through its own sales and distribution organization, which maintains sales offices and distribution centers 
throughout the United States and in Canada, Mexico, Europe, China, and South Korea.  Additionally, products are sold and marketed 
through a complement of agents, which, when combined with our sales organization, provide the Company broad geographic 
market representation.

The total amount of order backlog for the Piping Systems segment as of December 28, 2019 was not significant.

We compete with various companies, depending on the product line.  In the U.S. copper tube business, domestic competition 
includes Cerro Flow Products LLC, Cambridge-Lee Industries LLC (a subsidiary of Industrias Unidas S.A. de C.V.), and Wieland 
Copper Products LLC, as well as many actual and potential foreign competitors.  In the European copper tube business, we compete 
with several European-based manufacturers of copper tube as well as other foreign-based manufacturers.  In the Canadian copper 
tube business, our competitors include foreign-based manufacturers.  In the copper fittings market, our domestic competitors 
include Elkhart Products Company (a subsidiary of Aalberts Industries N.V.) and NIBCO, Inc.  We also compete with several 
foreign manufacturers.  Additionally, our copper tube and fittings businesses compete with a large number of manufacturers of 
substitute products made from other metals and plastic.

manufacturing industries.  Typical applications for impacts are high strength ordnance, high-conductivity electrical components, 
builders’  hardware,  hydraulic  systems,  automotive  parts,  and  other  uses  where  toughness  must  be  combined  with  varying 
complexities of design and finish.

Brass Value-Added Products manufactures brass and aluminum forgings; brass, aluminum, and stainless steel valves; fluid control 
solutions; and gas train assembles. Our forgings are used in a wide variety of products, including automotive components, brass 
fittings, industrial machinery, valve bodies, gear blanks, and computer hardware.  Our valves, fluid control systems, and gas train 
assemblies are used in the compressed gas, pharmaceutical, construction, and gas appliance markets.

On June 18, 2015, we acquired Sherwood Valve Products, LLC (Sherwood), which manufactures valves and fluid control solutions 
for the HVAC, refrigeration, and compressed gas markets.  The acquisition of Sherwood complements our existing brass businesses 
in the Industrial Metals segment.  

The segment sells its products primarily to domestic OEMs in the industrial, construction, HVAC, plumbing, and refrigeration 
markets.  The total amount of order backlog for the Industrial Metals segment as of December 28, 2019 was not significant.

Competitors, primarily in the brass rod market, include Chase Brass and Copper Company  LLC, a subsidiary of Global Brass 
and Copper Holdings, Inc., and others, both domestic and foreign.  

Climate Segment

The  Climate  segment  is  composed  of  Refrigeration  Products,  Fabricated  Tube  Products,  Westermeyer  Industries,  Inc. 
(Westermeyer), Turbotec Products, Inc. (Turbotec), ATCO Rubber Products, Inc. (ATCO), and Linesets, Inc.

HVAC and refrigeration markets. Fabricated Tube Products manufactures tubular assemblies and fabrications for OEMs in the 
4

 
HVAC and refrigeration markets. Westermeyer designs, manufactures, and distributes high-pressure components and accessories 
for the air-conditioning and refrigeration markets.  Turbotec manufactures coaxial heat exchangers and twisted tubes for the HVAC, 
geothermal, refrigeration, swimming pool heat pump, marine, ice machine, commercial boiler, and heat reclamation markets.  
ATCO manufactures and distributes insulated HVAC flexible duct systems.

We acquired Turbotec on March 30, 2015 and ATCO on July 2, 2018.  These acquisitions complement our existing businesses in 
the Climate segment.

The segment sells its products primarily to OEMs in the HVAC and refrigeration markets in the U.S.  The total amount of order 
backlog for the Climate segment as of December 28, 2019 was not significant.

Labor Relations

At December 28, 2019, the Company employed approximately 4,964 employees, of which approximately 1,579 were represented 
by various unions.  Those union contracts will expire as follows:

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

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 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’s  provision  for 
environmental matters related to all properties was $1.7 million for 2019, $2.0 million for 2018, and $7.5 million for 2017.  The 
reserve  for  environmental  matters  was  $20.9  million  at  December 28,  2019  and  $23.6  million  at  December 29, 
2018.  Environmental expenses related to non-operating properties are presented below operating income in the Consolidated 
Statements of Income, and costs related to operating properties are included in cost of goods sold.  We currently anticipate that 
we will need to make 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 14 – Commitments and 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 2019, 2018, or 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 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,

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.

Both the costs of raw materials used in our manufactured products (copper, brass, zinc, aluminum, and plastic 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’ 
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.

6

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.

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, 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.

As of January 31, 2020, the U.K. is no longer a member of the EU (Brexit).  As a result, we face risks and uncertainty regarding 
the form and consequences of the implementation of Brexit, including the 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 
7

 
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’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.

We have a number of employees who 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.

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 partners could expose us, our customers, our suppliers, and our employees to risks of misuse or improper 

8

   
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.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure information required to be disclosed in Company 
reports filed under the Securities Exchange Act of 1934, as amended (the Exchange Act), is recorded, processed, summarized, and 
reported within the time periods specified in the SEC’s rules and forms.  Disclosure controls and procedures are designed to provide 
reasonable assurance that information required to be disclosed in Company reports filed under the Exchange Act is accumulated 
and communicated to management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate, 
to allow timely decisions regarding required disclosure.

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has 
evaluated the effectiveness of the Company’s disclosure controls and procedures pursuant to Rule 13a-15(e) of the Exchange Act 
as of December 28, 2019.  Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have 
concluded that the Company’s disclosure controls and procedures are effective as of December 28, 2019 to ensure that information 
required to be disclosed in Company reports filed under the Exchange Act is (i) recorded, processed, summarized and reported 
within the time periods specified in the SEC rules and forms and (ii) accumulated and communicated to management, including 
the Company’s principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required 
disclosure.

Management’s Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as 
defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act.  Pursuant to the rules and regulations of the SEC, internal control 
over financial reporting is a process designed by, or under the supervision of, the Company’s principal executive and principal 
financial officers, and effected by the Company’s Board of Directors, management and other personnel, to provide reasonable 
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in 
accordance with accounting principles generally accepted in the United States and includes those policies and procedures that (i) 
pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of 
the  Company’s  assets;  (ii)  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 issuer 
are being made only in accordance with authorizations of the Company’s management and directors; and (iii) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that 
could have a material effect on the financial statements.  Due to inherent limitations, internal control over financial reporting may 
not prevent or detect misstatements.  Further, because of changes in conditions, effectiveness of internal control over financial 
reporting may vary over time.

As required by Rule 13a-15(c) under the Exchange Act, the Company’s management, with the participation of the Company’s 
Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s internal control over financial 
reporting  as  of  December 28,  2019  based  on  the  control  criteria  established  in  a  report  entitled  Internal  Control—Integrated 
Framework,  (2013  Framework)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission 
(COSO).  Based on such evaluation, management has concluded that our internal control over financial reporting was effective as 
of December 28, 2019.

Ernst & Young LLP, the independent registered public accounting firm that audited the Company’s financial statements included 
in this Annual Report on Form 10-K, has issued an attestation report on the Company’s internal control over financial reporting, 
which is included herein.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the Company’s fiscal quarter ended 
December 28, 2019, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control 
over financial reporting.

Report of Independent Registered Public Accounting Firm

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

Opinion on Internal Control over Financial Reporting

We have audited Mueller Industries, Inc.’s internal control over financial reporting as of December 28, 2019, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) (the COSO criteria). In our opinion, Mueller Industries, Inc. (the Company) maintained, in all 
material respects, effective internal control over financial reporting as of December 28, 2019, based on the 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’s Report on Internal 
Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial 
reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with 
respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities 
and Exchange Commission and the PCAOB.

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

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

Definition and Limitations of Internal Control Over Financial Reporting

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

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

FINANCIAL REVIEW

The Financial Review  section of  our Annual Report  on Form 10-K  consists of the  following: Management’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 “Item 1: Business” and 
our other detailed discussion of risk factors included in this MD&A.

OVERVIEW

We  are  a  leading  manufacturer  of  copper,  brass,  aluminum,  and  plastic  products.  The  range  of  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  tube  and  fittings;  refrigeration  valves  and  fittings;  compressed  gas  valves;  fabricated  tubular 
products; pressure vessels; steel nipples; and insulated flexible duct systems.  We also resell brass and plastic plumbing valves, 
plastic fittings, malleable iron fittings, faucets and plumbing specialty products.  Mueller’s operations are located throughout the 
United States and in Canada, Mexico, Great Britain, South Korea, the Middle East, and China.

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, Great Lakes Copper, 
Heatlink  Group,  Die-Mold,  European  Operations, Trading  Group,  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 Company disposed of Mueller-Xingrong (the Company’s Chinese joint venture) on June 21, 2017.  This business 
manufactured engineered copper tube primarily for air-conditioning applications in China.

• 

Industrial Metals:  The Industrial Metals segment is composed of Brass Rod & Copper Bar Products, Impacts & Micro 
Gauge, and Brass Value-Added Products.  The segment manufactures and sells brass and copper alloy rod, bar, and 
shapes; aluminum and brass forgings; aluminum impact extrusions; and gas valves and assemblies.   The segment 
manufactures and sells its products primarily to domestic OEMs in the industrial, transportation, construction, heating, 
ventilation, and air-conditioning, plumbing, refrigeration, and energy markets.

•  Climate:  The  Climate  segment  is  composed  of  Refrigeration  Products,  Fabricated  Tube  Products,  Westermeyer, 
Turbotec, ATCO, and Linesets, Inc.  The segment manufactures and sells refrigeration valves and fittings, line sets, 
fabricated tubular products, high pressure components, coaxial heat exchangers, and insulated HVAC flexible duct 
systems.  The segment sells its products primarily to the heating, ventilation, air-conditioning, and refrigeration markets 
in the U.S.

New  housing  starts  and  commercial  construction  are  important  determinants  of  our  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.  
Per the U.S. Census Bureau, actual housing starts in the U.S. were 1.29 million in 2019, which compares to 1.25 million in 2018

F-2

and  1.20  million  in  2017.  Mortgage  rates  remain  at  historically  low  levels,  as  the  average  30-year  fixed  mortgage  rate  was 
approximately 3.94 percent in 2019 and 4.54 percent in 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 $450.5 billion in 2019, $450.9 billion in 2018, and $444.0 billion in 
2017.  

Profitability of certain of our product lines depends upon the “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 and brass rod, two principal products 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.  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 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 2019 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 $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,

by Mueller-Xingrong, a business we sold during June 2017, and (ii) lower unit sales volume of $44.5 million in our non-domestic 
core product lines.

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:

The decrease in cost of goods sold in 2019 was primarily due to the decrease in sales volume in our core product lines and the 
decrease in the average cost of copper, our principal raw material.  This was partially offset by the increase in sales volume resulting 
from the acquisition of ATCO.  The increase in cost of goods sold in 2018 was primarily due to the increase in the average cost 
of copper, as well as the increase in sales volume in our domestic core product lines and related to businesses acquired.  This was 
partially offset by the decrease in sales volume resulting from the sale of Mueller-Xingrong and lower sales volume in our non-
domestic core product lines.

Depreciation  and  amortization  increased  in  2019  as  a  result  of  long-lived  assets  of  businesses  acquired.    Depreciation  and 
amortization increased in 2018 as a result of long-lived assets of businesses acquired as well as several new long-lived assets being 
placed into service, partially offset by the impact of the sale of long-lived assets at Mueller-Xingrong. 

Selling, general, and administrative expenses increased in 2019 primarily due to (i) expense recognized for contingent consideration 
arrangements  associated  with  businesses  acquired  of  $5.7  million,  (ii)  an  increase  in  employment  costs,  including  employee 
healthcare, of $4.9 million, (iii) incremental expenses of $4.7 million associated with ATCO and Die-Mold, (iv) a reduction of 
$3.5 million in fees received for services provided under certain third-party sales and distribution arrangements, and (v) an increase 
in product liability costs of $1.6 million.  These increases were partially offset by (i) income of $2.1 million recognized as a result 
of  the  reduction  of  contingent  consideration  arrangements  associated  with  businesses  acquired,  (ii)  a  decrease  in  legal  and 
professional fees of $1.4 million, (iii) higher foreign currency transaction gains of $1.4 million, (iv) a reduction of $0.8 million 
in fees received for services provided under certain equipment transfer and licensing agreements, and (v) a decrease in supplies 
and utilities of $0.5 million. The increase in selling, general, and administrative expenses in 2018 was primarily due to (i) incremental 
expenses of $9.8 million associated with ATCO, Heatlink Group, and Die-Mold and (ii) an increase in employment costs, including 
incentive compensation, of $4.7 million. These increases were partially offset by (i) fees of $3.5 million received for services 
provided under certain third-party sales and distribution arrangements in 2018 (fees from these arrangements are classified as a 
component of net sales in 2019), (ii) a reduction in product liability costs of $2.1 million, and (iii) the absence of expenses associated 
with Mueller-Xingrong of $1.2 million. 

During 2019, we recognized a net gain of $1.0 million on the sale of real property.  We also recognized an insurance recovery gain 
of $0.5 million related to the losses incurred due to the 2017 fire at our brass rod mill in Port Huron, Michigan.

During 2018, we recognized a gain of $2.7 million on the sale of real property and a gain of $0.7 million on the sale of manufacturing 
equipment, which were offset by a loss of $3.1 million on the sale of a corporate aircraft.  We also recognized an insurance recovery 
gain of $3.7 million related to the losses incurred due to the 2017 fire at our brass rod mill in Port Huron, Michigan.

During 2017, we recognized fixed asset impairment charges for certain copper fittings manufacturing equipment of $1.5 million
and a gain of $1.5 million on the sale of our interest in Mueller-Xingrong.

Interest expense increased in 2019 primarily as a result of increased borrowing costs associated with our unsecured $350.0 million 
revolving credit facility.  The increase in 2018 was primarily as a result of interest associated with the 6% Subordinated Debentures 
issued during the first quarter of 2017 as part of our special dividend, as well as increased borrowing costs associated with our 
unsecured $350.0 million revolving credit facility.

Environmental expense for our non-operating properties was significantly higher in 2017 than in 2019 or 2018 primarily as a result 
of ongoing remediation activities related to the Lead Refinery site.

Other income, net, was lower in 2019 primarily as a result of lower net periodic benefit income for our benefit plans, and higher 
in 2018 primarily as a result of higher net periodic benefit income for our benefit plans. 

Income tax expense was $35.3 million in 2019, representing an effective tax rate of 21.2 percent.  This rate was higher than what 
would be computed using the U.S. statutory federal rate primarily due to (i) the provision for state and local income taxes, net of 
the federal benefit, of $3.2 million, and (ii) the impact of investments in unconsolidated affiliates of $0.5 million.  These increases 
were partially offset by other adjustments of $3.3 million.

Income tax expense was $31.0 million in 2018, representing an effective tax rate of 20.6 percent.  This rate was lower than what 
would be computed using the U.S. statutory federal rate primarily due to (i) a reduction of the calculation of federal tax on the 
Company’s accumulated foreign earnings under the Tax Cuts and Jobs Act (the Act) of $4.4 million and (ii) a reduction for the 
impact of investments in unconsolidated affiliates of $2.8 million.  These reductions were partially offset by (i) the provision for 
state and local income taxes, net of the federal benefit, of $3.5 million and (ii) other adjustments of $3.1 million.

F-5

Income tax expense was $37.9 million in 2017, representing an effective tax rate of 29.8 percent.  This rate was lower than what 
would be computed using the U.S. statutory federal rate primarily due to (i) reductions for the effect of lower foreign tax rates 
when compared to the U.S. statutory rate and other foreign adjustments of $6.0 million, (ii) the U.S. production activities deduction 
of $1.6 million, (iii) the benefit of stock-based compensation deductions of $2.2 million, and (iv) the impact of the change in the 
federal tax rate under the Act on deferred taxes of $12.1 million.   These reductions were partially offset by (i) the accrual of federal 
tax on the Company’s accumulated foreign earnings under the Act of $12.9 million, (ii) the provision for state and local income 
taxes, net of the federal benefit, of $1.1 million, and (iii) other adjustments of $1.2 million.

During 2019, we recognized losses of $24.6 million on our investments in unconsolidated affiliates, net of foreign tax, compared 
to losses of $12.6 million in 2018.  The loss on these investments for 2019 included net losses of $22.0 million for Tecumseh and 
net  losses  of  $2.6  million  for  Mueller  Middle  East.    Included  in  the  losses  for Tecumseh  are  $6.4  million  of  severance  and 
restructuring expenses and a product liability settlement of $3.4 million.  These expenses were offset by a gain on the sale of land 
of $1.8 million.  

During 2018, we recognized losses of $12.6 million on our investments in unconsolidated affiliates, net of foreign tax, compared 
to losses of $2.1 million in 2017.  The loss on these investments for 2018 included net losses of $14.0 million and charges of $3.0 
million related to certain labor claim contingencies, offset by a gain of $7.0 million related to a settlement with the Brazilian 
Federal Revenue Agency for Tecumseh.  It also includes net losses of $2.6 million for Mueller Middle East. 

During 2017, the loss on these investments included net losses of $2.1 million for Tecumseh.

The decrease in net sales in 2019 was primarily attributable to (i) lower net selling prices of $70.6 million in the segment’s core 
product lines, primarily copper tube, and (ii) lower unit sales volume of $37.3 million in the segment’s core product lines.  These 
decreases were partially offset by incremental sales of $4.0 million recorded by Die-Mold.

The increase in net sales in 2018 was primarily attributable to (i) higher unit sales volume of $96.6 million in the segment’s 
domestic core product lines, primarily copper tube, (ii) higher net selling prices of $69.7 million in the segment’s core product 
lines, (iii) an increase in sales of $13.3 million in the segment’s non-core product lines, (iv) incremental sales of $9.6 million 
recorded by Heatlink Group, and (v) sales of $6.8 million recorded by Die-Mold.  These increases were partially offset by (i) the 
absence of sales of $67.3 million recorded by Mueller-Xingrong and (ii) lower unit sales volume of $44.5 million in the segment’s 
non-domestic core product lines.

The decrease in cost of goods sold in 2019 was primarily due to the decrease in the average cost of copper and the decrease in 
sales volume in the segment’s core product lines.  The increase in cost of goods sold in 2018 was primarily due to the increase in 
the average cost of copper and the increase in sales volume  in the segment’s domestic core product lines and related to the 
acquisitions of Heatlink Group and Die-Mold, partially offset by the decrease in sales volume resulting from the sale of Mueller-
Xingrong. 

Depreciation and amortization decreased in 2019 as a result of several long-lived assets becoming fully depreciated.  The increase
in 2018 was a result of several new long-lived assets being placed into service as well as long-lived assets of Heatlink Group and 
Die-Mold, partially offset by the impact of the sale of long-lived assets at Mueller-Xingrong.

Selling, general, and administrative expenses increased slightly for 2019, primarily due to (i) a reduction of $3.5 million in fees 
received for services provided under certain third-party sales and distribution arrangements, (ii) higher employment costs, including 
employee healthcare, of $0.9 million, and (iii) incremental expenses associated with Die-Mold of $0.6 million.  These increases 
were partially offset by (i) income of $2.1 million recognized as a result of the reduction of contingent consideration arrangements 
associated with businesses acquired, (ii) higher foreign currency transaction gains of $1.4 million, and (iii) a decrease in supplies 
and utilities of $0.6 million.  The increase in 2018 was primarily due to (i) incremental expenses associated with Die-Mold and 
Heatlink Group of $2.5 million, (ii) an increase in legal and professional fees of $1.6 million, (iii) an increase in foreign currency 
exchange rate losses of $0.6 million, and (iv) an increase in agent commissions of $0.5 million.  These increases were partially 
offset by (i) fees of $3.5 million received for services provided under certain third-party sales and distribution arrangements in 
2018 (fees from these arrangements are classified as a component of net sales in 2019) and (ii) the absence of expenses associated 
with Mueller-Xingrong of $1.2 million.   

During 2019, we recognized a gain of $1.2 million on the sale of real property.

During 2018,  we recognized a gain of $1.4 million on the sale of real property and a gain of $0.7 million on the sale of manufacturing 
equipment.

During 2017, we recognized fixed asset impairment charges for certain copper fittings manufacturing equipment of $1.5 million
and a gain of $1.5 million on the sale of our interest in Mueller-Xingrong.

The decrease in cost of goods sold in 2019 was primarily due to the decrease in sales volume in the segment’s core product lines 
and the decrease in the average cost of copper.  The increase in cost of goods sold in 2018 was primarily related to the increase
in the average cost of copper and the increase in sales volume in the segment’s core product lines..  

Depreciation and amortization in 2019 was consistent with 2018 and 2017. 

Selling, general, and administrative expenses decreased slightly in 2019 primarily due to lower employment costs, including 
incentive compensation, of $0.7 million.  The increase in 2018 was primarily due to an increase in legal fees of $0.2 million. 

During 2019, we recognized a loss of $0.3 million on the sale of real property and an insurance recovery gain of $0.5 million
related to the losses incurred due to the 2017 fire at our brass rod mill in Port Huron, Michigan.  

During 2018, we recognized a gain of $1.3 million on the sale of real property and an insurance recovery gain of $3.7 million 
related to the losses incurred due to the 2017 fire at our brass rod mill in Port Huron, Michigan.

Cost of goods sold increased in 2019 due to the increase in volume and change in product mix within the segment primarily 
resulting from the ATCO acquisition.  The increase in cost of goods sold in 2018 was related to the increase in volume and change

in product mix within the segment primarily resulting from the ATCO acquisition.  In addition, it included additional expense of 
$2.2  million  to  adjust ATCO’s  inventory  to  fair  value  as  part  of  purchase  price  accounting  during  2018.   Depreciation  and 
amortization increased in 2019 and 2018 primarily as a result of depreciation and amortization of the long-lived assets acquired 
at ATCO.  Selling, general, and administrative expenses increased in 2019 as a result of (i) expense of $5.7 million recognized for 
a contingent consideration arrangement associated with an acquired business, (ii) incremental expenses of $4.6 million associated 
with ATCO, (iii) an increase in employment costs of $1.7 million, (iv) an increase in agent commissions of $0.5 million, and (v) 
an increase in supplies, utilities, and rent costs of $0.4 million.  Selling, general, and administrative expenses increased in 2018
as a result of incremental expenses associated with ATCO.

During 2019, net cash provided by operating activities was primarily attributable to (i) consolidated net income of $106.2 million, 
(ii) depreciation and amortization of $43.0 million, (iii) a decrease in inventories of $39.6 million, (iv) losses from unconsolidated 
affiliates of $24.6 million, (v) stock-based compensation expense of $8.7 million, and (vi) a decrease in accounts receivable of 
$6.5 million.  These cash increases were partially offset by (i) an increase in other assets of $15.6 million, (ii) a decrease in other 
liabilities of $7.9 million, and (iii) a decrease in current liabilities of $7.1 million.  The fluctuations in accounts receivable and 
inventories were primarily due to decreased selling prices and sales volume in certain businesses and changes working capital 
needs in 2019.

During 2018, net cash provided by operating activities was primarily attributable to (i) consolidated net income of $106.8 million, 
(ii) depreciation and amortization of $39.9 million, (iii) a decrease in inventories of $27.5 million, (iv) a decrease in other assets 
of $14.4 million, (v) losses from unconsolidated affiliates of $12.6 million, and (vi) stock-based compensation expense of $8.0 
million.  These cash increases were offset by (i) a decrease in current liabilities of $15.7 million, (ii) a decrease in other liabilities 
of $14.8 million, and (iii) an increase in accounts receivable of $11.3 million.  The decrease in inventories was primarily driven 
by the use of excess inventory built at the end of 2017 due to a casting outage in our brass rod mill that impaired our ability to 
melt scrap returns.  The fluctuations in accounts receivable and current liabilities were primarily due to increased selling prices 
and sales volume in certain businesses and additional working capital needs in 2018.  The changes in other assets and liabilities 
are primarily attributable to the change in estimate of the one-time transition tax liability on accumulated foreign earnings under 
the the Act.

During 2017,  net cash provided by operating activities was primarily attributable to (i) consolidated net income of $87.0 million, 
(ii) depreciation and amortization of $34.2 million, and (iii) an increase in current liabilities of $10.7 million.  These cash increases 
were offset by an increase in inventories of $86.3 million, primarily driven by the increase in the price of copper and an excess 
inventory build of $38.9 million at the end of 2017 due to a casting outage in our brass rod mill that impaired our ability to melt 
scrap returns.

Cash Used in Investing Activities

The major components of net cash used in investing activities in 2019 included (i) capital expenditures of $31.2 million and (ii) 
investments in our unconsolidated affiliates, Tecumseh and Mueller Middle East, of $16.0 million.  These uses of cash were offset 
by (i) the $3.5 million working capital settlement received from the previous owners for the ATCO acquisition and (ii) proceeds 
on the sale of properties of $3.2 million.

The major components of net cash used in investing activities in 2018 included (i) $167.7 million for the purchases of ATCO and 
Die-Mold, net of cash acquired, and (ii) capital expenditures of $38.5 million.  These uses of cash were offset by proceeds on the 
sale of properties of $18.7 million.

The major components of net cash used in investing activities in 2017 included (i) capital expenditures of $46.1 million, (ii) $18.4 
million for the purchase of Heatlink Group, net of cash acquired, and (iii) investments in our joint venture in Bahrain of $3.3 
million.  These uses of cash were offset by (i) $17.5 million of proceeds from the sale of our 50.5 percent equity interest in Mueller-
Xingrong, net of cash sold, (ii) proceeds from the sale of properties of $12.3 million, and (iii) proceeds from the sale of securities 
of $1.8 million.

Cash Used in Financing Activities

For 2019, net cash used in financing activities consisted primarily of (i) $205.0 million used to reduce the debt outstanding under 
our Credit Agreement, (ii)  $22.3 million used for the payment of regular quarterly dividends to stockholders of the Company, 
(iii) $4.3 million used for repayment of debt by Jungwoo-Mueller, (iv) $3.2 million used for payment of contingent consideration 
related to ATCO, and (v) $1.8 million used to repurchase common stock.  These uses of cash were offset by the issuance of debt 
under our Credit Agreement of $100.0 million.

For 2018, net cash used in financing activities consisted primarily of (i) $165.0 million used to reduce the debt outstanding under 
our Credit Agreement, (ii) $33.6 million used to repurchase common stock, (iii) $22.7 million used for the payment of regular 
quarterly dividends to stockholders of the Company, and (iv) $2.9 million used for repayment of debt by Jungwoo-Mueller.  These 
uses of cash were offset by the issuance of debt under our Credit Agreement of $200.0 million.

For 2017, net cash used in financing activities consisted primarily of (i) $196.9 million used for the payment of the special dividend 
and the regular quarterly dividends to stockholders of the Company, (ii) $110.0 million used to reduce the debt outstanding under 
our Credit Agreement, (iii) $3.4 million used for repayment of debt by Jungwoo-Mueller and Mueller-Xingrong, and (iv) $2.9 
million used for payment of dividends to noncontrolling interests.  These uses of cash were partially offset by the issuance of debt 
of $70.0 million under our Credit Agreement.

Liquidity and Outlook

We believe that cash provided by operations, funds available under the Credit Agreement, and cash on hand will be adequate to 
meet our liquidity needs, including working capital, capital expenditures, and debt payment obligations.  Our current ratio was 
3.0 to 1 as of December 28, 2019.

As of December 28, 2019, $65.3 million of our cash and cash equivalents were held by foreign subsidiaries.  The undistributed 
earnings of most of the foreign subsidiaries are considered to be permanently reinvested.  These earnings could be remitted to the 
U.S. with a minimal tax cost.  Accordingly, no additional income tax liability has been accrued with respect to these earnings or 
on any additional outside basis differences that may exist with respect to these entities.  

We expect the reduction in the U.S. federal tax rate from 35 percent to 21 percent under the Act to provide ongoing benefits to 
liquidity.  For 2020, we expect our effective tax rate on consolidated earnings to be in the range of 22 to 26 percent.  We believe 
that cash held domestically, funds available through the Credit Agreement, and cash generated from U.S. based operations will 
be adequate to meet the future needs of our U.S. based operations.

Fluctuations in the cost of copper and other raw materials affect the Company’s liquidity.  Changes in material costs directly impact 
components  of  working  capital,  primarily  inventories,  accounts  receivable,  and  accounts  payable.  The  price  of  copper  has 
fluctuated significantly and averaged approximately $2.72 in 2019, $2.93 in 2018, and $2.80 in 2017.

We have significant environmental remediation obligations which we expect to pay over future years.  Approximately $4.4 million
was spent during 2019 for environmental matters.  As of December 28, 2019, we expect to spend $0.8 million in 2020, $0.7 million
in 2021, $0.6 million in 2022, $0.8 million in 2023, $0.7 million in 2024, and $17.3 million thereafter for ongoing projects.  

F-11

Cash used to fund pension and other postretirement benefit obligations was $0.8 million in 2019 and $1.9 million in 2018.  We 
anticipate making contributions of approximately $1.0 million to these plans in 2020.

The Company declared and paid a quarterly cash dividend of 10.0 cents per common share during each quarter of 2017, 2018, 
and 2019.  Additionally, during the first quarter of 2017 the Company distributed a special dividend composed of $3.00 in cash 
and $5.00 in principal amount of the Company’s 6% Subordinated Debentures (Debentures) due 2027 for each share of common 
stock outstanding.  Payment of dividends in the future is dependent upon our financial condition, cash flows, capital requirements, 
and other factors.

Capital Expenditures

During 2019 our capital expenditures were $31.2 million.   We anticipate investing approximately $45.0 million to $50.0 million 
for capital expenditures in 2020.

Long-Term Debt

The Company’s Credit Agreement provides for an unsecured $350.0 million revolving credit facility which matures on December 6, 
2021.  Funds borrowed under the Credit Agreement may be used for working capital purposes and other general corporate purposes.  
In addition, the Credit Agreement provides a sublimit of $50.0 million for the issuance of letters of credit, a sublimit of $25.0 
million for loans and letters of credit made in certain foreign currencies, and a swing  line loan sublimit of $15.0 million.  Outstanding 
letters of credit and foreign currency loans reduce borrowing availability under the Credit Agreement.  Total borrowings under 
the Credit Agreement were $90.0 million at December 28, 2019.

The Debentures distributed as part of our special dividend are subordinated to all other funded debt of the Company and are 
callable, in whole or in part, at any time at the option of the Company, subject to declining call premiums during the first five 
years.  The Debentures also grant each holder the right to require the Company to repurchase such holder’s Debentures in the 
event of a change in control at declining repurchase premiums during the first five years.  Interest is payable semiannually on 
September 1 and March 1.  Total Debentures outstanding as of December 28, 2019 were $284.5 million.

Jungwoo-Mueller has several secured revolving credit arrangements with a total borrowing capacity of KRW 25.8 billion (or 
approximately $21.9 million).  Borrowings are secured by the real property and equipment of Jungwoo-Mueller and were bearing 
interest  at  a  rate  of  2.55  percent  as  of  December 28,  2019.   Total  borrowings  at  Jungwoo-Mueller  were  $5.8  million  as  of 
December 28, 2019.

As of December 28, 2019, the Company’s total debt was $386.3 million or 36.8 percent of its total capitalization.

Covenants contained in the Company’s financing obligations require, among other things, the maintenance of minimum levels of 
tangible net worth and the satisfaction of certain minimum financial ratios.  As of December 28, 2019, we were in compliance 
with all of our debt covenants.

Share Repurchase Program

The Company’s Board of Directors has extended, until August 2020, its authorization to repurchase up to 20 million shares of the 
Company’s common stock through open market transactions or through privately negotiated transactions.  We may cancel, suspend, 
or extend the time period for the repurchase of shares at any time.  Any repurchases will be funded primarily through existing cash 
and cash from operations.  The Company may hold any shares repurchased in treasury or use a portion of the repurchased shares 
for  stock-based  compensation  plans,  as  well  as  for  other  corporate  purposes.  From  its  initial  authorization  in  1999  through 
December 28, 2019, the Company had repurchased approximately 6.2 million shares under this authorization.

(1)  This includes contractual supply commitments totaling $634.3 million at year-end prices; these contracts contain variable 
pricing  based  on  Comex  and  the  London  Metals  Exchange  quoted  prices.  These  commitments  are  for  purchases  of  raw 
materials, primarily copper cathode and brass scrap, that are expected to be consumed in the ordinary course of business. 

(2)  These payments represent interest on long-term debt based on balances and rates in effect at December 28, 2019.

The above obligations will be satisfied with existing cash, funds available under the Credit Agreement, and cash generated by 
operations.  The Company has no off-balance sheet financing arrangements.

MARKET RISKS

The Company is exposed to market risks from changes in raw material and energy costs, interest rates, and foreign currency 
exchange rates.  To reduce such risks, we may periodically use financial instruments.  Hedging transactions are authorized and 
executed pursuant to policies and procedures.  Further, we do not buy or sell financial instruments for trading purposes.  A discussion 
of the Company’s accounting for derivative instruments and hedging activities is included in “Note 1 - Summary of Significant 
Accounting Policies” in the Notes to Consolidated Financial Statements.

Cost and Availability of Raw Materials and Energy

Raw materials, primarily copper and brass, represent the largest component of the Company’s variable costs of production.  The 
cost of these materials is subject to global market fluctuations caused by factors beyond our control.  Significant increases in the 
cost of metal, to the extent not reflected in prices for our finished products, or the lack of availability could materially and adversely 
affect our business, results of operations and financial condition.

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 28, 2019, 
we held open futures contracts to purchase approximately $21.3 million of copper over the next 12 months related to fixed-price 
sales orders and to sell approximately $1.9 million of copper over the next seven 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 28, 2019.

F-13

 
 
Interest Rates

The Company had variable-rate debt outstanding of $97.0 million at December 28, 2019 and $202.6 million at December 29, 
2018.  At this borrowing 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 exposure on variable-rate debt is based on LIBOR.

Foreign Currency Exchange Rates

Foreign currency exposures arising from transactions include firm commitments and anticipated transactions denominated in a 
currency other than an entity’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 28, 2019, we had 
open forward contracts with a financial institution to sell approximately 0.1 million euros, 21.7 million Swedish kronor, and 8.1 
million Norwegian kroner through April 2020.

The Company’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.  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 $397.1 million at December 28, 2019
and $376.6 million at December 29, 2018.  The potential loss in value of the Company’s net investment in foreign subsidiaries 
resulting from a hypothetical 10 percent adverse change in quoted foreign currency exchange rates at December 28, 2019 and 
December 29, 2018 amounted to $39.7 million and $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, and the South Korean won.  During 2019, the value of the British pound increased approximately three percent, 
the Mexican peso increased approximately 4 percent, the Canadian dollar increased approximately four percent, and the South 
Korean won decreased approximately four percent, relative to the U.S. dollar.  The resulting net foreign currency translation gains 
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

The Company’s accounting policies are more fully described in “Note 1 - Summary of Significant Accounting 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’s  financial  condition  and  results  of  operations  and  require 
management’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 28, 2019 and December 29, 2018, our inventory valuation reserves were $6.3 million and $7.0 million, respectively.  
The expense recognized in each of these periods was immaterial to our Consolidated Financial Statements.

F-14

 
Impairment of Goodwill

As of December 28, 2019, we had $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 2019 we recorded $1.5 million in additional 
goodwill associated with our ATCO and Die-Mold acquisitions in conjunction with the 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, management 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’s fair value, not to exceed the total amount of goodwill allocated to the reporting unit.  

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, B&K LLC, Great 
Lakes, Heatlink Group, Die-Mold, European Operations, Jungwoo-Mueller, Westermeyer, Turbotec, and 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’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.

We evaluated each reporting unit during the fourth quarters of 2019 and 2018, as applicable.  The estimated fair value of each of 
these reporting units exceeded its carrying values in 2019 and 2018, and we do not believe that any of these reporting units were 
at risk of impairment as of December 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, internal 
and third party estimates and analyses of cleanup costs and ongoing monitoring costs, communications with regulatory 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.  

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 presented below operating income in the Consolidated Statements of Income.

F-15

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.

Notes to Consolidated Financial Statements

Note 1 – Summary of Significant Accounting Policies

Nature of Operations

The principal business of Mueller Industries, Inc. is the manufacture and sale of copper tube and fittings; line sets; brass and copper 
alloy rod, bar, and shapes; aluminum and brass forgings; aluminum impact extrusions; PEX plastic tube and fittings; refrigeration 
valves and fittings; compressed gas valves; fabricated tubular products; pressure vessels; steel nipples; and insulated flexible duct 
systems.  The Company also resells brass and plastic plumbing valves, plastic fittings, malleable iron fittings, faucets, and plumbing 
specialty  products.  The  Company  markets  its  products  to  the  HVAC,  plumbing,  refrigeration,  hardware,  and  other 
industries.  Mueller’s operations are located throughout the United States and in Canada, Mexico, Great Britain, South Korea, the 
Middle East, and China.

Fiscal Years

The Company’s fiscal year consists of 52 weeks ending on the last Saturday of December.  These dates were December 28, 2019, 
December 29, 2018, and December 30, 2017.

Reclassifications

Certain reclassifications have been made to the prior years’ Consolidated Financial Statements to conform to the current year’s 
presentation.

Basis of Presentation

The Consolidated Financial Statements include the accounts of Mueller Industries, Inc. and its majority-owned subsidiaries.  The 
noncontrolling interests represent separate private ownership interests of 40 percent of Jungwoo Metal Ind. Co., LTD (Jungwoo-
Mueller) and 49.5 percent of Jiangsu Mueller-Xingrong Copper Industries Limited (Mueller-Xingrong), which the Company sold 
during 2017.  See “Note 2 – Acquisitions and Dispositions” for additional information.

Revenue Recognition

Given the nature of the Company’s business and product offerings, sales transactions with customers are generally comprised of 
a single performance obligation that involves delivery of the products identified in the contracts with customers.  Performance 
obligations are generally satisfied at the point in time of shipment and payment is generally due within sixty days.   Variable 
consideration  is  estimated  for  future  rebates  on  certain  product  lines  and  product  returns.    The  Company  records  variable 
consideration as an adjustment to the transaction price in the period it is incurred.  Since variable consideration is settled within 
a short period of time, the time value of money is not significant.  The cost of shipping product to customers is expensed as incurred 
as a component of cost of goods sold.

The Company’s Domestic Piping Systems Group engages in certain transactions where it acts as an agent.  Revenue from these 
transactions is recorded on a net basis. 

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 “Note 2 – Acquisitions and Dispositions” for additional information.

Cash Equivalents and Restricted Cash

Temporary investments with original maturities of three months or less are considered to be cash equivalents.  These investments 
are stated at cost.  At December 28, 2019 and December 29, 2018, temporary investments consisted of money market mutual 
F-23

funds, commercial paper, bank repurchase agreements, and U.S. and foreign government securities totaling approximately $0.5 
million and $0.6 million, respectively.

Amounts included in restricted cash relate to required deposits in brokerage accounts that facilitate the Company’s hedging activities 
as well as imprest funds for the Company’s self-insured workers’ compensation program.  See “Note 4 – Cash, Cash Equivalents, 
and Restricted Cash” for additional information.

Allowance for Doubtful Accounts

The Company provides an allowance for receivables that may not be fully collected.  In circumstances where the Company is 
aware of a customer’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’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’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 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 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’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 5 
– 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 9 – Property, Plant, and Equipment, Net” for additional information.

F-24

 
Goodwill

Goodwill is 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 
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’s fair value, not to exceed the total amount of goodwill allocated to the 
reporting unit.  

Fair value for the Company’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’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’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’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 10 
– Goodwill and Other Intangible Assets” for additional information.

Investments in Unconsolidated Affiliates

The Company owns a 50 percent interest in an unconsolidated affiliate that acquired Tecumseh Products Company (Tecumseh).  
The Company also owns a 50 percent interest in a second unconsolidated affiliate that provides financing to 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’s proportionate share of earnings 
or losses and distributions.

The Company records its proportionate share of the investees’ 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’s 
proportionate share of the 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 unconsolidated affiliates is equal to the current equity investment plus the investees’ net 
accumulated losses.

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

The investments in unconsolidated affiliates are assessed periodically for impairment and written down when the carrying amount 
is not considered fully recoverable.  See “Note 11 – Investments in Unconsolidated Affiliates” for additional information.

Self-Insurance Accruals

The Company is primarily self-insured for 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 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, 

F-25

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.

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.  See “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, 
internal and third party estimates and analyses of cleanup costs and ongoing monitoring costs, communications with regulatory 
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.  

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 presented below operating income in the Consolidated Statements of Income.  
See “Note 14 – Commitments and 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.  There were no awards 
excluded from the computation of diluted earnings per share for the year ended December 28, 2019, and approximately 54 thousand
stock-based awards excluded from the computation of diluted earnings per share for the year ended December 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’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 was 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’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’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  15  –  Income Taxes”  for  additional 
information.

F-26

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 17 – 
Stock-Based 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’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’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.  Changes in the fair value of a derivative that is qualified, designated, and 
highly effective as a cash flow hedge are recorded in 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 derivatives 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 derivative 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’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.

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 7 – Derivative Instruments and Hedging Activities” for additional information.

F-27

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 28, 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.   

Foreign Currency Translation

For foreign subsidiaries for 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 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 of long-lived assets (including goodwill).

Recently Adopted Accounting Standard

In July 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-11, Leases 
(Topic 842): Targeted Improvements and ASU No. 2018-10, Codification Improvements to Topic 842, Leases.  The ASUs 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 each lease with a term of more than 12 months.  Recognition, measurement and presentation of expenses 
will depend on classification as a financing or operating lease.  The guidance also requires 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 
F-28

 
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 annual periods beginning in 2020.  An entity 
is 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 guidance 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  does  not  expect  the  adoption  of  the ASU  to  have  a  material  impact  on  its 
Consolidated Financial Statements.

Note 2 – Acquisitions and Dispositions

2018 Acquisitions

ATCO

On  July  2,  2018,  the  Company  entered  into  a  stock  purchase  agreement  pursuant  to  which  the  Company  acquired  all  of  the 
outstanding capital stock of ATCO Rubber Products, Inc. (ATCO) for approximately $158.1 million, net of the working capital 
adjustments.  The total purchase price consisted of $151.8 million in cash at closing and a contingent consideration arrangement 
which requires the Company to pay the former owner up to $12.0 million based on EBITDA growth of the acquired business.  
ATCO is an industry leader in the manufacturing and distribution of insulated HVAC flexible duct systems and will support the 
Company’s strategy to grow its Climate Products businesses to become a more valuable resource to its HVAC customers.  The 
acquired business is reported in the Company’s Climate segment. 

For the year ended December 28, 2019, ATCO had net sales of approximately $190.1 million.  For the year ended December 29, 
2018, the Company’s total net sales included $90.0 million of revenue recognized by ATCO from the date of acquisition.  ATCO 
had revenues of approximately $166.0 million in its fiscal year ending December 31, 2017 (unaudited). 

The following table presents condensed pro forma consolidated results of operations as if the ATCO acquisition has occurred at 
the beginning of 2017.  The pro forma information does not purport to be indicative of the results that would have been obtained 
if the operations had actually been combined during the periods presented and is not necessarily indicative of operating results to 
be expected in future periods.  The most significant pro forma adjustments to the historical results of operations relate to the 
application of purchase accounting and the financing structure.

outstanding  shares  of  Pexcor  Manufacturing  Company  Inc.  and  Heatlink  Group  Inc.  (collectively,  Heatlink  Group)  for 
approximately $17.2 million, net of working capital adjustments.  The total purchase price consisted of $16.3 million in cash at 
closing and a contingent consideration arrangement which requires the Company to pay the former owners up to $2.2 million
based on EBITDA growth of the acquired business.  Heatlink Group, based out of Calgary, Alberta, Canada, produces and sells 
a complete line of products for PEX plumbing and radiant systems.  The business complements the Company’s existing businesses 
within the Piping Systems segment.

Purchase Price Allocations

These acquisitions were accounted for using the acquisition method of accounting whereby the total purchase price was allocated 
to tangible and intangible assets acquired and liabilities assumed based on respective fair values.

The following table summarizes the allocation of the purchase price to acquire these businesses, which were financed by available 
cash balances, as well as the assets acquired and liabilities assumed at the respective acquisition dates.  During 2019, the valuation 
of the ATCO acquisition was finalized.  Changes to the purchase price allocation from the amounts presented in the Company’s 
2018 Annual Report on Form 10-K included the valuation of the contingent consideration, intangible assets, and working capital.   
These changes resulted in a decrease to goodwill of $0.5 million.  During 2019, the valuation of the Die-Mold acquisition was 
finalized.  Changes to the purchase price allocation from the amounts presented in the Company’s 2018 Annual Report on Form 
10-K included the recognition of a deferred tax liability of $2.0 million that resulted from a basis difference in the long-lived assets 
acquired. This change resulted in an increase to goodwill.

On June 21, 2017, the Company entered into a definitive equity transfer agreement with Jiangsu Xingrong Hi-Tech Co. Ltd. and 
Jiangsu Baiyang Industries Co. Ltd. (Baiyang), together, the minority partners in Mueller-Xingrong (the Company’s Chinese joint 
venture), pursuant to which the Company sold its 50.5 percent equity interest in Mueller-Xingrong to Baiyang for approximately 
$18.3 million.  Mueller-Xingrong manufactured engineered copper tube primarily for air-conditioning applications in China and 
was included in the Piping Systems segment.  Mueller-Xingrong reported net sales of $67.3 million and net losses of $9 thousand
in 2017, compared to net sales of $121.5 million and net income of $62 thousand in 2016.  The carrying value of the assets disposed 
totaled $56.8 million, consisting primarily of accounts receivable, inventories, and long-lived assets.  The carrying value of the 
liabilities disposed (consisting primarily of current debt and accounts payable), noncontrolling interest, and amounts recognized 
in AOCI totaled $36.2 million.  Since the disposal constituted a complete liquidation of the Company’s investment in a foreign 
entity, the Company removed from AOCI and recognized a cumulative translation gain of $3.8 million.  As a result of the disposal, 
the Company recognized a net gain on the sale of this business of $1.5 million in the Consolidated Financial Statements.

Note 7 – Derivative Instruments and Hedging Activities

The Company’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.

F-37

Commodity Futures Contracts

Copper and brass represent the largest component of the Company’s variable costs of production.  The cost of these materials is 
subject to global market fluctuations caused by factors beyond the Company’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 28, 2019, the Company held open futures contracts to purchase approximately $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 $1.4 million net gain position, which 
was determined by obtaining quoted market prices (level 1 within the fair value hierarchy).  In the next 12 months, the Company 
will  reclassify  into  earnings  realized  gains  or  losses  relating  to  cash  flow  hedges.  At  December 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 28, 
2019, the Company held open futures contracts to sell approximately $1.9 million of copper over the next five months related to 
copper inventory.  The fair value of those futures contracts was a $0.1 million net loss position, which was determined by obtaining 
quoted market prices (level 1 within the fair value hierarchy).  

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 28, 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 28, 2019 and December 29, 2018, the Company had recorded restricted cash in other 
current assets of $0.2 million and $3.6 million, respectively, as collateral related to open derivative contracts under the master 
netting arrangements.

Mold, European Operations, Jungwoo-Mueller, Westermeyer, Turbotec, and ATCO.  Several factors give rise to goodwill in the 
Company’s acquisitions, such as the expected benefit from synergies of the combination and the existing workforce of the acquired 
businesses.  There were no impairment charges resulting from the 2019, 2018, or 2017 annual impairment tests as the estimated 
fair value of each of the reporting units exceeded its carrying value.

The Company’s Credit Agreement provides for an unsecured $350.0 million revolving credit facility (Revolving Credit Facility) 
that matures on December 6, 2021.  Borrowings under the Revolving Credit Facility bear interest, at the Company’s option, at 
LIBOR or Base Rate as defined by the Credit Agreement, plus a variable premium.  LIBOR advances may be based upon the one, 
three, or six-month LIBOR.  The variable premium is based upon the Company’s debt to total capitalization ratio, and can range 
from 112.5 to 162.5 basis points for LIBOR based loans and 12.5 to 62.5 basis points for Base Rate loans.  At December 28, 2019, 
the premium was 150.0 basis points for LIBOR loans and 50.0 basis points for Base Rate loans.  Additionally, a commitment fee 
is payable quarterly on the total commitment less any outstanding loans or issued letters of credit, and varies from 15.0 to 30.0 
basis points based upon the Company’s debt to total capitalization ratio.  Availability of funds under the Revolving Credit Facility 
is reduced by the amount of certain outstanding letters of credit, which are used to secure the Company’s payment of insurance 
deductibles and certain retiree health benefits, totaling approximately $11.9 million at December 28, 2019.  Terms of the letters 
of credit are generally renewable annually.

Jungwoo-Mueller

Jungwoo-Mueller has several secured revolving credit arrangements with a total borrowing capacity of KRW 25.8 billion (or 
approximately $21.9 million).  Borrowings are secured by the real property and equipment of Jungwoo-Mueller.

Covenants contained in the Company’s financing obligations require, among other things, the maintenance of minimum levels of 
tangible net worth and the satisfaction of certain minimum financial ratios.  At December 28, 2019, the Company was in compliance 
with all debt covenants.

December 28, 2019 and December 29, 2018, respectively, and 39 and 37 percent of the above plan assets at December 28, 2019
and December 29, 2018, respectively.

As of December 28, 2019, $1.6 million of the actuarial net loss and $0.9 million of the prior service credit will, through amortization, 
be recognized as components of net periodic benefit cost in 2020.

The aggregate status of all overfunded plans is recognized as an asset and the aggregate status of all underfunded plans is recognized 
as a liability in the Consolidated Balance Sheets.  The amounts recognized as a liability are classified as current or long-term on 
a plan-by-plan basis.  Liabilities are classified as current to the extent the actuarial present value of benefits payable within the 
next 12 months exceeds the fair value of plan assets, with all remaining amounts classified as long-term.  

As of December 28, 2019 and December 29, 2018, the total funded status of the plans recognized in the Consolidated Balance

Rate of inflation

The Company’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 4.0 to 7.0 percent for 2020, gradually decrease to 4.1 percent through 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’s pension fund assets are as follows:

Equity securities (includes equity mutual funds)

Cash and equivalents (includes money market funds)
Alternative investments

At December 28, 2019, the long-term target allocation, by asset category, of assets of the Company’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’ 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 3.84 percent for 2019 and 5.05 percent in 2018.

The Company’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’s plan asset investments:

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

Mutual funds – Valued at the net asset value of shares held by the plans at December 28, 2019 and December 29, 2018, respectively, 
based upon quoted market prices.

Limited partnerships – Limited partnerships include investments in various Cayman Island multi-strategy hedge funds.  The 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.

The following table sets forth by level, within the fair value hierarchy, the assets of the plans at fair value:

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  two  collective  bargaining  agreements  in  Port  Huron, 
Michigan, the Local 218 IAM and Local 44 UAW that expire on May 7, 2023 and 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.

F-50

 
 
 
 
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 2017.  The Company’s contributions are less than five 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’s actuary must certify the plan’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’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 2018, 
the IAM Plan was determined to have green zone 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’s matching contribution to the 401(k) plans was $5.4 million in 2019, $5.1 million
in 2018, and $5.1 million in 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’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 $223 thousand, $153 thousand, and $182 thousand for the years ended 2019, 2018, and 
2017, respectively.

Note 14 – Commitments and Contingencies

Environmental

The Company is subject to federal, state, local, and foreign environmental laws and regulations.  For all properties, the Company 
has provided and charged to expense $1.7 million in 2019, $2.0 million in 2018, and $7.5 million in 2017 for pending environmental 
matters.  Environmental reserves totaled $20.9 million at December 28, 2019 and $23.6 million at December 29, 2018.  As of 
December 28, 2019, the Company expects to spend $0.8 million in 2020, $0.7 million in 2021, $0.6 million in 2022, $0.8 million
in 2023, $0.7 million in 2024, and $17.3 million thereafter for ongoing projects.  

Non-operating Properties

Southeast Kansas Sites

The Kansas Department of Health and Environment (KDHE) has contacted the Company regarding environmental contamination 
at three 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. 

F-51

East La Harpe.  At the East La Harpe site, the Company and two 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’s reserve for its proportionate share of the remediation costs associated with these three 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 that 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’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’s discharge 
permit and will concurrently issue a new order.  It is expected that the new 10-year permit will include an order requiring continued 
implementation of BMP through 2030 to address residual discharges of acid rock drainage.  At this site, MRRC spent approximately 
$1.9 million from 2017 through 2019 for remediation, and currently estimates that it will spend between approximately $12.7 
million and $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’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 $0.7 million 
from 2017 through 2019 with respect to this site.  Approximate costs to comply with the post-closure permit, including associated 
general and administrative costs, are estimated at between $1.8 million and $2.3 million over the next 17 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’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 
F-52

 
 
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 two 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 Bonita Peak Mining District NPL site.

Operating Properties

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 $0.6 million to $0.9 million over the next six 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, 
F-53

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’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 
would 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’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’s protests, and CBP’s response to 
Southland’s protests is currently pending.  Given the procedural posture and issues raised by this legal dispute, the Company 
cannot estimate the amount of potential duty liability, if any, that may result from CBP’s asserted claims.

Equal Employment Opportunity Commission Matter

On October 5, 2016, the Company received a demand letter from the Los Angeles District Office of the United States Equal 
Employment Opportunity Commission (EEOC).  The EEOC alleged that between May 2011 and April 2015, various Company 
employees were terminated in violation of the Americans with Disabilities Act (ADA), and that certain of the Company’s employee 
leave and attendance policies were discriminatory in nature.  Thereafter, the Company, in consultation with its liability insurers, 
entered into conciliation and mediation efforts with the EEOC for purposes of resolving the claims.  At the conclusion of those 
efforts, the Company and the EEOC reached agreement on a consensual resolution of the EEOC’s claims, which includes both 
monetary and equitable relief.

On June 28, 2018, the EEOC filed a complaint against the Company on behalf of a group of unidentified claimants in the United 
States District Court for the Central District of California alleging that the Company engaged in unlawful employment practices 
in violation of the ADA.  On July 13, 2018, the District Court approved a Consent Decree between the Company and the EEOC 
to resolve the EEOC’s claims.  The Consent Decree, which is currently set to expire in January 2021, provided that the Company 
pay up to $1.0 million in monetary relief to fund individual claims for discrimination under the ADA as approved by the EEOC.  
That amount was fully within the limits of the Company’s applicable insurance coverage, and has been paid to claimants designated 
as eligible by the EEOC.  The Consent Decree also required the Company to take a series of proactive measures to cultivate a 
work  environment  free  from  unlawful  discrimination.    Those  measures  have  included,  among  others,  assistance  with  the 
identification of potential 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.

Guarantees

Guarantees, in the form of letters of credit, are issued by the Company generally to assure the payment of insurance deductibles, 
certain retiree health benefits, and debt at certain unconsolidated affiliates.  The terms of the guarantees are generally one year
but  are  renewable  annually  as  required.  These  letters  are  primarily  backed  by  the  Company’s  revolving  credit  facility.  The 
maximum payments that the Company could be required to make under its guarantees at December 28, 2019 were $11.9 million.

Other

The Company is involved in certain litigation as a result of claims that arose in the ordinary course of business, which management 
believes will not have a material adverse effect on the Company’s financial position, results of operations, or cash flows.  It may 
also realize the benefit of certain legal claims and litigation in the future; these gain contingencies are not recognized in the 
Consolidated Financial Statements.

The Tax Cuts and Jobs Act (the Act) was enacted on December 22, 2017.  The Act reduced the U.S. federal corporate income tax 

F-55

 
 
 
 
 
 
 
 
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 made 
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 $12.9 million, or 22 cents per diluted share, at December 30, 2017.  During 2018, 
the Company continued to refine its calculation of the transition tax.  Following the completion of this analysis, the Company 
recorded a reduction to income tax expense of $4.4 million, or eight 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 deferred 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 benefit 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  tax  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 future years or provide for the tax expense related to GILTI in the year the tax is incurred.  The Company has elected to 
provide for the tax expense related to GILTI in the 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 2019, 2018, and 2017.  

The statute of limitations is open for the Company’s federal tax return for 2015 and all subsequent years.  The statutes of limitations 
for most 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.

As of December 28, 2019, after consideration of the federal impact, the Company had state income tax credit carryforwards of 
$2.3 million, all of which expire by 2022, and other state income tax credit carryforwards of $11.7 million with unlimited lives.  The 
Company had state net operating loss (NOL) carryforwards with potential tax benefits of $8.4 million, after consideration of the 
federal impact, expiring between 2020 and 2034.  The state tax credit and NOL carryforwards are offset by valuation allowances 
totaling $10.7 million.

As of December 28, 2019, the Company had other foreign tax attributes with potential tax benefits of $5.0 million that have an 
unlimited life.  These attributes were offset by a valuation allowance totaling $3.0 million. The Company also had other foreign 
tax attributes of $0.9 million, which have limited lives expiring between 2025 and 2039.

Income taxes paid were approximately $41.8 million in 2019, $38.1 million in 2018, and $42.5 million in 2017.

Note 16 – Equity

The Company’s Board of Directors has extended, until August 2020, its authorization to repurchase up to 20 million shares of the 
Company’s common stock through open market transactions or through privately negotiated transactions.  The Company has no 
obligation to purchase any shares and may cancel, suspend, or extend the time period for the purchase of shares at any time.  Any 
purchases will be funded primarily through existing cash and cash from operations.  The Company may hold any shares purchased 
in  treasury  or  use  a  portion  of  the  repurchased  shares  for  its  stock-based  compensation  plans,  as  well  as  for  other  corporate 
purposes.  From its initial authorization in 1999 through December 28, 2019, the Company has repurchased approximately 6.2 
million shares under this authorization.

Note 17 – 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, as well as restricted stock awards.  Generally, the 
awards vest within five years from the grant date.  Any unexercised options expire after not more than ten years.  

During the years ended December 28, 2019, December 29, 2018, and December 30, 2017, the Company recognized stock-based 
compensation, as a component of selling, general, and administrative expense, in its Consolidated Statements of Income of $8.7 
million, $8.0 million, and $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 
2019, 2018, and 2017 was $8.78, $9.64, and $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:

Expected term
Expected price volatility
Risk-free interest rate
Dividend yield

2019

1.4%

7.6 years
27.2%
2.9%
1.3%

7.7 years
28.9%
2.1%
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 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.

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

The total intrinsic value of options exercised was $1.6 million, $0.9 million, and $10.2 million in 2019, 2018, and 2017, respectively.  
The total fair value of options that vested was $1.0 million each year in 2019, 2018, and 2017.

At December 28, 2019, the aggregate intrinsic value of all outstanding options was $6.3 million with a weighted average remaining 
contractual term of 5.5 years.  Of the outstanding options, 613 thousand are currently exercisable with an aggregate intrinsic value 
of $5.8 million, a weighted average exercise price of $22.34, and a weighted average remaining contractual term of 4.5 years.  

The total compensation expense not yet recognized related to unvested options at December 28, 2019 was $1.5 million, with an 
average expense recognition period of 3.0 years.

F-58

 
 
Restricted Stock Awards

The fair value of each restricted stock award equals the fair value of the Company’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 2019, 2018, and 2017 was $28.82, $32.04, and $30.97, respectively.

The aggregate intrinsic value of outstanding and unvested awards was $33.7 million at December 28, 2019.  Total compensation 
expense for restricted stock awards not yet recognized was $18.7 million with an average expense recognition period of 3.2 years.  
The total fair value of awards that vested was $5.6 million, $3.7 million, and $3.5 million in 2019, 2018, and 2017, respectively.

The Company generally issues treasury shares when options are exercised or restricted stock awards are granted.  A summary of

Note 20 – Subsequent Events

On February 12, 2020, Mueller Copper Tube Company, a wholly owned subsidiary of the Company, collected approximately  
$21.9 million related to its claim under the Deepwater Horizon Economic and Property Damage Settlement Program, which as 
previously  reported  by  the  Company,  was  originally  approved  in  November  2018,  subject  to  appeal.   The  collected  amount 
represents settlement proceeds received after the payment of fees and expenses.

On January 17, 2020, the Company entered into a stock purchase agreement pursuant to which the Company acquired all of the 
outstanding stock of Shoals Tubular, Inc. (STI) for approximately $15.4 million, net of working capital adjustments.  STI is a 
manufacturer of brazed manifolds, headers, and distributor assemblies used primarily by manufactures of residential heating and 
air conditioning units.  STI will be reported with and complements the Company’s existing business in its Climate segment.  

In January 2020, the Company completed the purchase of its corporate headquarters located in Collierville, TN for $10.6 million.  
In 2019, the building was leased and was included in the operating lease right-of-use assets line item in the Consolidated Balance 
Sheet.  In 2020, it will be included in property, plant, and equipment, net.  The corporate headquarters lease represents $9.3 million
and $9.5 million of the total operating lease right-of-use-assets and related lease liabilities at year-end.  Remaining lease payments 
under the previous agreement were $14.5 million at the end of 2019 and are included in the operating lease maturities table in 
“Note 8 – Leases.”

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Mueller Industries, Inc. (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) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated 
financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  at  December 28,  2019  and 
December 29, 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 28, 
2019, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as  of December 28, 2019, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
framework), and our report dated February 26, 2020 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error 
or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that 
were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are 
material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective  or  complex  judgments.    The 
communication of the critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken 
as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit 
matters or on the accounts or disclosures to which they relate.

F-63

Description of
the Matter

Defined Benefit Pension Obligation
At 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. 

Description of
the Matter

Valuation of Goodwill - Heatlink Group Reporting Unit
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 first 
day of the fourth quarter unless circumstances indicate the need to accelerate the timing of the evaluation.

Auditing management’s annual goodwill impairment test for the Heatlink Group reporting unit was complex 
and highly judgmental due to the significant estimates required to determine the fair value of the reporting 
unit.  Fair value for the Heatlink Group reporting unit is determined using the income approach, incorporating 
market participant considerations and management’s assumptions on revenue growth rates, operating margins, 
discount rates and a terminal value, among other factors.  Fair value estimates of reporting units with fair 
values that do not significantly exceed their carrying values are sensitive to these assumptions and are directly 
impacted by the condition of the markets in which the reporting unit operates.

F-64

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. 

We have served as the Company’s auditor since 1991.

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.
