ENVIRONMENTAL, HEALTH & SAFETY
SCOPE 1 AND 2 GREENHOUSE GAS EMISSIONS 

Ducommun is committed to continuously improving the 

scope and transparency of our environmental programs  

and reporting. For the 2021 fiscal year, Ducommun  

reported both Scope 1 and Scope 2 greenhouse gas 

emissions for current and prior years. Scope 1 emissions 

are direct emissions from natural gas consumption at our 

performance centers. Scope 2 emissions are indirect 

emissions and come from sources such as electricity from 

local utilities. As shown in Figure 1 on the left, there was  

a 28% decrease in combined Scope 1 and 2 greenhouse 

gas emissions in 2021 compared to 2018, and a 12% 

Scope 1: Direct Emissions from Natural Gas

decrease in 2021 compared to 2020 (on an absolute,

non-normalized basis). Over time, the greenhouse gas 

emission trend shows a reduction of 18% of Scope 1 

emissions and a reduction of 31% of Scope 2 emissions  

in 2021 compared to 2018. We aim to focus on energy 

efficiency initiatives that are pilot tested at selected 

performance centers before implementing them enterprise-

wide to address climate risk.

SAFETY METRICS: REDUCTION OF LOST TIME INCIDENT 

RATE AND TOTAL RECORDABLE INCIDENT RATE 

Ducommun tracks the number of lost time incidents and 

total recordable incidents incurred by our employees to 

measure the effectiveness of health and safety programs.  

In 2021, we decreased our lost time incident rate by more 

than 56% compared to the baseline year 2018 (or -18% 

compared to 2020), and we reduced the total recordable 

incident rate by 68% compared to the baseline year 2018 

(or -54% compared to 2020). We also reduced the number

ITEM 1. BUSINESS

GENERAL

PART I

Ducommun Incorporated (“Ducommun,” “the Company,” “we,” “us” or “our”) is a leading global provider of engineering and 
manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace and 
defense (“A&D”), industrial, medical and other industries (collectively, “Industrial”). Ducommun differentiates itself as a full-
service solution-based provider, offering innovative, value-added proprietary products and manufacturing solutions to our 
customers in our primary businesses of electronics, structures, and integrated solutions. We operate through two primary 
business segments:  Electronic Systems and Structural Systems. We are the successor to a business that was founded in 
California in 1849 and reincorporated in Delaware in 1970.

ACQUISITIONS

Acquisitions have been an important element of our growth strategy. We have supplemented our organic growth by identifying, 
acquiring and integrating acquisition opportunities that result in broader, more sophisticated product and service offerings while 
diversifying and expanding our customer base and markets.

For example, on December 16, 2021, we acquired 100% of the outstanding equity interests of Magnetic Seal LLC (f/k/a 
Magnetic Seal Corporation, “MagSeal”), a privately-held leading provider of high-impact, military-proven magnetic seals for 
critical systems in aerospace and defense applications, offering sealing solutions that are engineered to perform in high-speed, 
high-vibration, and other challenging environments for $69.5 million, net of cash acquired. A portion of the purchase price was 
funded by drawing down on our revolving credit facility. This draw down on our revolving credit facility was paid off by 
December 31, 2021. The acquisition of MagSeal will continue to advance our strategy to diversify and offer more customized, 
value-driven engineered products with aftermarket opportunities, and is included in our Structural Systems segment.

PRODUCTS AND SERVICES

Business Segment Information

We operate through two primary strategic businesses, Electronic Systems and Structural Systems, each of which is a reportable

AEROSPACE AND DEFENSE END-USE MARKETS OVERVIEW

Our largest end-use markets are the aerospace and defense markets and our revenues from these markets represented 94% of 
our total net revenues in 2021. These markets are serviced by suppliers which are stratified, from the highest value provided to 
the lowest, into four tiers: original equipment manufacturers (“OEMs”), Tier One, Tier Two, and Tier Three. The OEMs 
provide the highest value and are also known as prime contractors (“Primes”). We derive a significant portion of our revenues 
from subcontracts with OEMs. As the prime contractor for various programs and platforms, the OEMs sell to their customers, 
who may include, depending upon the application, the U.S. Federal Government, foreign, state and local governments, global 
commercial airline carriers, regional jet carriers and various other customers. The OEMs also sell to global leasing companies 
that lease commercial aircraft. A significant portion of our revenues is earned from subcontracts with the Primes. Tier One 
suppliers manufacture aircraft sections and purchase assemblies. Tier Two suppliers provide more complex, value-added parts 
and may also assume more design risk, manufacturing risk, supply chain risk and project management risk than Tier Three 
suppliers. Tier Three suppliers principally provide components or detailed parts. We currently compete with Tier One, Tier 
Two, and Tier Three suppliers. Our business growth strategy is to differentiate ourselves from competitors by providing more 
complex assemblies to our customers as a higher value added supplier.

Commercial Aerospace End-Use Market

The commercial aerospace end-use market is highly cyclical and is impacted by the level of global air passenger traffic in 
general, which in turn is influenced by global economic conditions, fleet fuel and maintenance costs and geopolitical 
developments. Revenues from the commercial aerospace end-use market represented 24% of our total net revenues for 2021.

The COVID-19 pandemic has caused and continues to cause an unprecedented adverse impact to demand for civil air travel, 
creating a significant challenge for some of our customers and the entire commercial aerospace manufacturing and services 
sector. As the number of infections from COVID-19 continues to decline in various parts of the world, along with the increase 
in the number of people being fully vaccinated, it should result in the steady increase in consumer confidence on the safety of 
air travel. The latest International Air Transport Association (“IATA”) release reported that passenger traffic in 2021 recovered 
to approximately 40% of 2019 levels even as international markets faced continued reopening challenges. In addition, global 
economic activity is improving, but continues to be impacted by COVID-19, and governments continue to restrict travel to 
contain the spread of the virus. While the recovery is accelerating, we continue to expect that it will remain uneven as travel 
restrictions and varying regional travel protocols impact air travel. 

Further, airline financial performance, which also plays a role in the demand for new capacity, has been adversely impacted by 
the COVID-19 pandemic. According to IATA, net losses in 2021 for the airline industry are expected to be approximately $52 
billion, compared to $138 billion in 2020. Our customers are taking actions to combat the effects of the COVID-19 pandemic 

5

Table of Contents

on the market by preserving liquidity. This comes in many forms such as deferral of advances and other payments to suppliers, 
deferrals of deliveries, reduced spending, and in some cases, cancellation of orders. While the outlook is improving and new 
orders are increasing in 2021, we continue to face a challenging environment in the near to medium-term as airlines have 
adjusted to reduced air traffic, which in turn, has resulted in lower demand for commercial aerospace products. The current 
environment is also affecting the financial viability of some airlines.

In The Boeing Company’s (“Boeing”) 2021 Annual Report on Form 10-K filed with the Securities and Exchange Commission 
(the “SEC”), they indicated that they expect commercial air travel to return to 2019 levels in 2023 to 2024, and a few years 
beyond that for the industry to return to the long-term trend growth.

The long-term outlook for the industry remains positive due to the fundamental drivers of air travel demand:  economic growth, 
increasing propensity to travel due to increased trade, globalization, and improved airline services driven by liberalization of air 
traffic rights between countries. The COVID-19 pandemic has reduced the near to medium-term demand, but Boeing’s 
commercial market outlook forecast projects a four percent growth rate for passenger and cargo traffic over a 20 year period. 
Based on long-term global economic growth projections of two and seven tenths percent average annual gross domestic product 
(“GDP”) growth, Boeing projects demand for 43,610 new airplanes over the next 20 years. However, the industry remains 
vulnerable to various developments including fuel price spikes, credit market fluctuations, acts of terrorism, natural disasters, 
conflicts, epidemics, pandemics, and increased global environmental regulations. We believe we are well positioned given our 
product capabilities and our initiatives to increase operating efficiencies to participate in the near term recovery and the long 
term projected growth rate for commercial air traffic and build rates for large commercial aircraft for the airframe 
manufacturing industry. If the recovery is slower than anticipated or any of those various developments occur, it could have a 
material adverse effect on our results of operations, financial position, and/or cash flows.

Defense End-Use Market

Our defense end-use market includes products used in military and space, including technologies and structures applications. 
The defense end-use market is highly cyclical and is impacted by the level of government defense spending. Government 
defense spending is impacted by national defense policies and priorities, political climates, fiscal budgetary constraints, U.S. 
Federal budget deficits, projected economic growth and the level of global military or security threats, or other conflicts. 
Revenues from the military and space end-use market in 2021 represented 70% of our total net revenues during 2021.

The FY 2022 National Defense Authorization Act (“NDAA”), enacted by the U.S. President in December 2021, is the annual 
policy bill that establishes, continues, or modifies federal programs, and provides the prerequisites for Congress to appropriate 
budget authority for defense programs. The FY 2022 NDAA authorized approximately $25 billion more than the U.S. President 
requested in the FY 2022 budget request. However, there continues to be uncertainty with respect to future program-level 
appropriations for the U.S. DoD and other government agencies. Future budget cuts or investment priority changes, including 
changes associated with the authorizations and appropriations process, could result in reductions, cancellations, and/or delays of 
existing contracts or programs. Any of these impacts could have a material effect on our results of operations, financial 
position, and/or cash flows. For additional information related to our revenues from customers whose principal sales are to the 
U.S. Government and our direct sales to the U.S. Government, see “Risk Factors” contained within Part I, Item 1A of this 
Annual Report on Form 10-K (“Form 10-K”).

INDUSTRIAL END-USE MARKETS OVERVIEW

Our industrial, medical and other (collectively, “Industrial”) end-use markets are diverse and are impacted by the customers’ 
needs for increasing electronic content and a desire to outsource. Factors expected to impact these markets include capital and 
industrial goods spending and general economic conditions. Our products are used in heavy industrial manufacturing systems 
and certain medical applications. Revenues from the Industrial end-use markets were 6% of our total net revenues during 2021. 

We believe our business in these markets in the long-term, is stable and we are well positioned in these markets even though the 
COVID-19 pandemic has had and will continue to have at least a near term impact on our business.

SALES AND MARKETING

Our commercial revenues are substantially dependent on airframe manufacturers’ production rates of new aircraft. Deliveries of 
new aircraft by airframe manufacturers are dependent on the demand and financial capacity of its customers, primarily airlines 
and leasing companies, to purchase the aircraft. Thus, revenues from commercial aircraft could be affected as a result of 
changes in new aircraft orders, or the cancellation or deferral by airlines of purchases of ordered aircraft. Further, our revenues 
from commercial aircraft programs could be affected by changes in our customers’ inventory levels and changes in our 
customers’ aircraft production build rates. Due to the continuing COVID-19 pandemic, while both major large aircraft 
manufacturers, Boeing and Airbus SE (“Airbus”), have announced a ramp up in build rates, it will take longer to reach pre-
COVID-19 pandemic levels. While the ramp up in production and demand will be slower in the near and medium future, we 

6

Table of Contents

will continue to identify opportunities to expand our presence and offerings with both major large aircraft manufacturers and 
their supply chain.

Military components manufactured by us are employed in many of the country’s front-line fighters, bombers, rotary-wing 
aircraft and support aircraft, as well as land and sea-based applications. Our defense business is diversified among a number of 
military manufacturers and programs. In the space sector, we are expanding our presence with unmanned aerial vehicles and 
continue to support various satellite programs.

Our sales into the Industrial end-use markets are customer focused in the various markets and driven primarily by their capital 
spending and manufacturing outsourcing demands.

We continue to broaden and diversify our customer base in the end-use markets we serve by providing innovative product and 
service solutions by drawing on our core competencies, experience and technical expertise. Net revenues related to military and 
space, commercial aerospace, and Industrial end-use markets in 2021 and 2020 were as follows:

Many of our contracts are firm fixed price contracts subject to termination at the convenience of the customer (as well as for 
default). In the event of termination for convenience, the customer generally is required to pay the costs we have incurred and 
certain other fees through the date of termination, plus a reasonable profit. Larger, long-term government subcontracts may 
have provisions for milestone payments, progress payments or cash advances for purchase of inventory.

Our marketing efforts primarily consist of developing strong, long-term relationships with our customers, which provide the 
basis for future sales. These close relationships allow us to gain a better insight into each customer’s business needs, identify 
ways to provide greater value to the customer, and allow us to be designated early in the design process for various products 
and/or high volume products.

SEASONALITY

The timing of our revenues is governed by the purchasing patterns of our customers, and, as a result, we may not generate 
revenues equally during the year. However, no material portion of our business is considered to be seasonal.

MAJOR CUSTOMERS

We currently generate the majority of our revenues from the aerospace and defense industries. As a result, we have significant 
revenues from certain customers. The Boeing Company (“Boeing”) and Raytheon Technologies Corporation (“Raytheon”) 
were our largest customers, with Boeing generating 8% and Raytheon generating 24% of our 2021 net revenues. Revenues from 
our top 10 customers, including Boeing and Raytheon were 61% of total net revenues during 2021. Net revenues by major 
customer for 2021 and 2020 were as follows:

We perform concurrent engineering with our customers and product development activities under our self-funded programs, as 
well as under contracts with others. Concurrent engineering and product development activities are performed for commercial, 
military and space applications.

RAW MATERIALS AND COMPONENTS

Raw materials and components used in the manufacturing of our products include aluminum, titanium, steel and carbon fibers, 
as well as a wide variety of electronic interconnect and circuit card assemblies and components. These raw materials are 
generally available from a number of suppliers and are generally in adequate supply. However, from time to time, and 
exacerbated by the COVID-19 pandemic, we have experienced increases in lead times for and limited availability of, 
aluminum, titanium and certain other raw materials and/or components. Moreover, certain components, supplies and raw 
materials for our operations are purchased from single source suppliers and occasionally, directed by our customers. In such 
instances, we strive to develop alternative sources and design modifications to minimize the potential for business interruptions.

COMPETITION

The markets we serve are highly competitive, and our products and services are affected by varying degrees of competition. We 
compete worldwide with domestic and international companies in most markets. These companies may have competitive 
advantages as a result of greater financial resources, economies of scale and bundled products and services that we do not offer. 
Additional information related to competition is discussed in Risk Factors contained within Part I, Item 1A of this Form 10-K. 
Our ability to compete depends principally upon the breadth of our technical capabilities, the quality of our goods and services, 
competitive pricing, product performance, design and engineering capabilities, new product innovation, the ability to solve 
specific customer needs, and customer relationships.

PATENTS AND LICENSES

We have several patents, but we do not believe that our operations are dependent upon any single patent or group of patents. In 
general, we rely on technical superiority, continual product improvement, exclusive product features, superior lead time, on-
time delivery performance, quality, and customer relationships to maintain our competitive advantage.

REMAINING PERFORMANCE OBLIGATIONS AND BACKLOG

We define performance obligations as customer placed purchase orders (“POs”) with firm fixed price and firm delivery dates. 
The majority of the long-term agreements (“LTAs”) we enter into do not meet the definition of a contract under Accounting 
Standards Codification 606 (“ASC 606”) and thus, the backlog amount is greater than the remaining performance obligations 
amount as defined under ASC 606. Revenue based on remaining performance obligations is subject to delivery delays or 
program cancellations, which are beyond our control. Remaining performance obligations were $814.1 million at December 31, 
2021. We anticipate recognizing an estimated 70% or $570.0 million of our remaining performance obligations during 2022.

We define backlog as potential revenue that is based on customer placed POs and LTAs with firm fixed price and expected 
delivery dates of 24 months or less. Backlog is subject to delivery delays or program cancellations, which are beyond our

Table of Contents

control. Backlog is affected by timing differences in the placement of customer orders, and tends to be concentrated in several 
programs to a greater extent, than our net revenues. Backlog in Industrial markets tends to be of a shorter duration and is 
generally fulfilled within a three month period. As a result of these factors, trends in our overall level of backlog may not be 
indicative of trends in our future net revenues. Backlog was $905.2 million at December 31, 2021, compared to $807.7 million 
at December 31, 2020. The increase in backlog was primarily in the commercial aerospace end-use market and industrial end-
use market. 

ENVIRONMENTAL MATTERS

Our business, operations and facilities are subject to numerous stringent federal, state and local environmental laws and 
regulations issued by government agencies, including the Environmental Protection Agency (“EPA”). Among other matters, 
these regulatory authorities impose requirements that regulate the emission, discharge, generation, management, transport and 
disposal of hazardous and non-hazardous materials, pollutants and contaminants. These regulations govern public and private 
response actions to hazardous or regulated substances that could be or have been released into the environment, or endanger 
human health, and they require us to obtain and maintain licenses and permits in connection with our operations. We may also 
be required to investigate and remediate the effects of the release or disposal of materials at sites associated with past and 
present operations. Additionally, this extensive regulatory framework imposes significant compliance burdens and risks on us. 
We anticipate that capital expenditures will continue to be required for the foreseeable future to upgrade and maintain our 
environmental compliance efforts, however, we do not expect such expenditures to be material in 2022 and the near term.

Structural Systems has been directed by California environmental agencies to investigate and take corrective action for 
groundwater contamination at its facilities located in Adelanto (a.k.a., El Mirage) and Monrovia, California. Based on currently 
available information, we have accrued $1.5 million at December 31, 2021 for our estimated liabilities related to these sites. For 
further information, see Note 14 in the accompanying notes to consolidated financial statements included in Part IV, Item 15(a) 
of this Form 10-K. In addition, see Risk Factors contained within Part I, Item 1A of this Form 10-K for certain risks related to 
environmental matters.

HUMAN CAPITAL

Our employees are critical to our success. We promote a culture of honesty, respect, trust, and teamwork through our Code of 
Business Conduct. Also, we have been engaged in a number of social matters and issues, both within the Company in our 
management of human capital, and externally with our community based initiatives.

Employee Safety and Health

The safety of our workforce is our highest priority as evidenced by our initial and continuing response to the COVID-19 
pandemic. To this end, we focus on protecting the health and safety of our employees and establishing a safe work environment 
by following the COVID-19 safety recommendations issued by the Centers for Disease Control and Prevention at all of our 
facilities.

Diversity and Inclusion

Diversity and inclusion is important to our current and future success. We implemented diversity and inclusion initiatives in 
2019 to help accelerate the process of developing a diverse talent pool. To that end, we are seeing an increase in the number of 
women and individuals from underrepresented communities being promoted into leadership roles. In 2020, we partnered with 
the Fund II Foundation to utilize its innovative internX platform to provide access to highly qualified and diverse science, 
technology, engineering and math (“STEM”) students. We believe a diverse hiring process at the intern level will result in 
inclusive hiring going forward and help us develop a diverse leadership team as our interns continue in their careers.

Talent Acquisition, Retention, and Development

We attract, develop, and retain employee talent by offering competitive compensation packages and fostering a culture of care 
about their well-being. In addition, we endeavor to be a proactive corporate citizen by being responsive and supportive of the 
needs of our employees to attract qualified talent. We strive to provide opportunities for qualified members of underrepresented 
communities and women for advancement within our company and award scholarships to the children and grandchildren of our 
employees so that they may develop the skills that will support their entry into the workforce. In addition, in 2018, we 
implemented an Employee Stock Purchase Plan (“ESPP”) to provide employees the opportunity to share in the ownership of 
our company and benefit from our performance through the purchase of our company’s stock. The ESPP allows eligible 
employees to accumulate contributions through after-tax payroll deductions to purchase shares of our company’s stock at a 15% 
discount and serves as one of the key retention mechanisms for our human capital.

Workforce Demographics

As of December 31, 2021, we had a highly skilled workforce of 2,480 employees, of which 465 are subject to collective 
bargaining agreements expiring in April 2022 and June 2024. Historically, we have been successful in negotiating renewals to 
expiring agreements without material disruption of operating activities, and believe our relations with our employees are good. 
See Risk Factors contained within Part I, Item 1A of this Form 10-K for additional information regarding certain risks related to 
our employees.

AVAILABLE INFORMATION

General information about us can be obtained from our website address at www.ducommun.com. Our Annual Reports on Form 
10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to those reports, if any, are available 
free of charge on our website as soon as reasonably practicable after they are filed with or furnished to the SEC. Information 
included on our website is not incorporated by reference in this Annual Report on Form 10-K. The SEC also maintains a

company.

ITEM 1A. RISK FACTORS

Our business, financial condition, results of operations and cash flows may be affected by known and unknown risks, 
uncertainties and other factors. We have summarized below the significant, known material risks to our business. Additional 
risk factors not currently known to us or that we currently believe are immaterial may also impair our business, financial 
condition, results of operations and cash flows. Any of these risks, uncertainties and other factors could cause our future 
financial results to differ materially from recent financial results or from currently anticipated future financial results. The risk 
factors below should be considered together with the information included elsewhere in this Annual Report on Form 10-K 
(“Form 10-K”) as well as other required filings by us with the SEC.

CAPITAL STRUCTURE RISKS

Our indebtedness could limit our financing options, adversely affect our financial condition, and prevent us from 
fulfilling our debt obligations.

In December 2019, we completed the refinancing of a portion of our existing debt by entering into a new revolving credit 
facility (“2019 Revolving Credit Facility”) to replace the then existing revolving credit facility that was entered into in 
November 2018 (“2018 Revolving Credit Facility”) and entered into a new term loan (“2019 Term Loan”). The 2019 
Revolving Credit Facility is a $100.0 million senior secured revolving credit facility that matures on December 20, 2024 
replacing the $100.0 million 2018 Revolving Credit Facility that would have matured on November 21, 2023. The 2019 Term 
Loan is a $140.0 million senior secured term loan that matures on December 20, 2024. We also have an existing $240.0 million 
senior secured term loan that was entered into in November 2018 that matures on November 21, 2025 (“2018 Term Loan”). The 
original amounts available under the 2019 Revolving Credit Facility, 2019 Term Loan, and 2018 Term Loan (collectively, the 
“Credit Facilities”) in aggregate, totaled $480.0 million. In conjunction with entering into the 2019 Revolving Credit Facility 
and the 2019 Term Loan, we drew down the entire $140.0 million on the 2019 Term Loan and used those proceeds to pay off 
and close the 2018 Revolving Credit Facility of $58.5 million, paid down a portion of the 2018 Term Loan of $56.0 million, 
paid the accrued interest associated with the amounts being paid down on the 2018 Revolving Credit Facility and 2018 Term 
Loan, paid the fees related to this transaction, and the remainder available for general corporate purposes. The $56.0 million, 
pay down on the 2018 Term Loan paid all the required quarterly installment payments on the 2018 Term Loan until maturity.

At December 31, 2021, we had a total of $287.7 million of outstanding long-term debt under the Credit Facilities. The total 
long-term debt was primarily the result of our acquisitions, including LaBarge, Inc. in 2011, Lightning Diversion Systems, LLC 
(“LDS”) in September 2017, Certified Thermoplastics Co., LLC (“CTP”) in April 2018, and Nobles Worldwide, Inc. 
(“Nobles”) in October 2019.

Our ability to obtain additional financing or complete a debt refinancing in the future may be limited. Should we not have ready 
access to capital markets, we may have to undertake alternative financing plans, such as selling assets; reducing or delaying 
scheduled expansions and/or capital investments; or seeking various other forms of capital. Our ability to complete reasonable 
alternative financing plans may be affected by circumstances and economic events outside of our control. We cannot ensure that 
we would be able to refinance our debt or enter into alternative financing plans in adequate amounts on commercially 
reasonable terms, terms acceptable to us or at all, or that such plans guarantee that we would be able to meet our debt 
obligations.

Table of Contents

Our level of debt could:

•

•

•

•

•

•

•

•

•

limit our ability to obtain additional financing to fund capital expenditures, investments or acquisitions or other 
general corporate requirements;

require a portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby 
reducing the amount of cash flows available for working capital, capital expenditures, investments or acquisitions 
or other general corporate purposes;

increase our vulnerability to adverse changes in general economic, industry and competitive conditions;

place us at a disadvantage compared to other, less leveraged competitors;

expose us to the risk of increased borrowing costs and higher interest rates as all of our borrowings under our 
Credit Facilities bear interest at variable rates, which could further adversely impact our cash flows;

limit our flexibility to plan for and react to changes in our business and the industry in which we compete;

restrict us from making strategic acquisitions;

expose us to risk of unfavorable changes in the global credit markets; and

make it more difficult for us to satisfy our obligations with respect to the Credit Facilities and our other debt.

The occurrence of any one of these events could have an adverse effect on our business, financial condition, results of 
operations and ability to satisfy our obligations in respect of our outstanding debt.

We require a considerable amount of cash to run our business.

Our ability to make payments on our debt in the future and to fund planned capital expenditures and working capital needs, will 
depend upon our ability to generate significant cash in the future. Our ability to generate cash is subject to economic, financial, 
competitive, legislative, regulatory and other factors that may be beyond our control.

The terms of the 2019 Term Loan require that we make installment payments of 1.25% of the initial outstanding principal 
balance on a quarterly basis, on the last day of each calendar quarter. We were required to make installment payments of 0.25% 
of the outstanding principal balance of the 2018 Term Loan amount on a quarterly basis, however, the $56.0 million we paid as 
part of the December 2019 refinancing paid all the required quarterly installment payments on the 2018 Term Loan until 
maturity. In addition, if we exceed the annual excess cash flow threshold, we are required to make an annual additional 
principal payment based on the consolidated adjusted leverage ratio. Further, the undrawn portion of the commitment of the 
2019 Revolving Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated 
total net adjusted leverage ratio. 

On December 16, 2021, we entered into a sale-leaseback transaction for the building and related land for our Gardena 
performance center located in Carson, California (“Sale-Leaseback Agreement”). The building and related land was sold for 
$143.1 million and we recognized a gain of $132.5 million. See Note 5 to our consolidated financial statements included in Part 
IV, Item 15(a) of this Annual Report on Form 10-K for further discussion. Also on December 16, 2021, we acquired 100% of 
the outstanding equity interests of Magnetic Seal LLC (f/k/a Magnetic Seal Corporation, “MagSeal”), for a purchase price of 
$69.5 million, net of cash acquired, all payable in cash. A portion of the proceeds from the sale-leaseback transaction was 
subsequently utilized to pay down the amount drawn on the 2019 Revolving Credit Facility to close the MagSeal acquisition. 
See Note 2 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K for 
further discussion.

On November 29, 2021, we entered into forward interest rate swaps, all with an effective date of January 1, 2024, for an 
aggregate total notional amount of $150.0 million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 
(“Forward Interest Rate Swaps”). In October 2015, we entered into interest rate cap hedges designated as cash flow hedges, 
with a portion of these interest rate cap hedges maturing on a quarterly basis, with notional value in aggregate, totaling $135.0 
million. However, all of these interest rate cap hedges matured in June 2020. At December 31, 2021, the outstanding balance on 
the Credit Facilities was $287.7 million with an average interest rate of 3.27%. Should interest rates increase significantly, our 
debt service cost will increase. Any inability to generate sufficient cash flow could have a material adverse effect on our 
financial condition or results of operations. See Note 1 and Note 8 to our consolidated financial statements included in Part IV, 
Item 15(a) of this Annual Report on Form 10-K for further discussion.

While we expect to meet all of our financial obligations, we cannot ensure that our business will generate sufficient cash flow 
from operations in an amount sufficient to enable us to pay our debt or to fund our other liquidity needs.

11

Table of Contents

We require a considerable amount of cash to fund our anticipated voluntary principal prepayments on our Credit 
Facilities.

Our ability to continue to reduce the debt outstanding under our Credit Facilities through voluntary principal prepayments will 
be a contributing factor to our ability to keep our interest rate towards the lower end of the interest rate range as defined in the 
Credit Facilities. Our ability to make such prepayments will depend upon our ability to generate significant cash in the future. 
We cannot ensure that our business will generate sufficient cash flow from operations to fund any such prepayments.

The covenants in our Credit Facilities impose restrictions that may limit our operating and financial flexibility.

We are required to comply with a leverage covenant as defined in the 2018 Term Loan agreement. The leverage covenant is 
defined as Consolidated Funded Indebtedness less unrestricted cash and cash equivalents in excess of $5.0 million, divided by 
consolidated earnings before interest, taxes and depreciation and amortization (“EBITDA”) and other adjustments.

At December 31, 2021, we were in compliance with the leverage covenant under the Credit Facilities. However, there is no 
assurance that we will continue to be in compliance with the leverage covenant in future periods.

The Credit Facilities’ agreements contains a number of significant restrictions and covenants that limit our ability, among other 
things, to incur additional indebtedness, to create liens, to make certain payments, to make certain investments, to engage in 
transactions with affiliates, to sell certain assets or enter into mergers.

These covenants could materially and adversely affect our ability to finance our future operations or capital needs. Furthermore, 
they may restrict our ability to expand, pursue our business strategies and otherwise conduct our business. Our ability to comply 
with these covenants may be affected by circumstances and events beyond our control, such as prevailing economic conditions 
and changes in regulations, and we cannot ensure that we will be able to comply with such covenants. These restrictions also 
limit our ability to obtain future financings to withstand a future downturn in our business or the economy in general. 

A breach of any covenant in the Credit Facilities could result in a default under the Credit Facilities. A default, if not waived, 
could result in acceleration of the debt outstanding under the agreement. A default could permit our lenders to foreclose on any 
of our assets securing such debt. Even if new financing were available at that time, it may not be on terms or amounts that are 
acceptable to us or terms as favorable as our current agreements. If our debt is in default for any reason, our business, results of 
operations and financial condition could be materially and adversely affected.

We may be adversely affected by changes in LIBOR reporting practices, the method in which LIBOR is determined, or 
the LIBOR replacement rate.

In July 2017, the Financial Conduct Authority, the authority that regulates London Interbank Offering Rate (“LIBOR”), 
announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. However, for USD-
LIBOR, the relevant date has been deferred to at least June 30, 2023 for certain tenors and at which time, the LIBOR 
administrator has indicated it intends to cease publication of USD-LIBOR. Despite this deferral, the LIBOR administrator has 
advised that no new contracts using USD-LIBOR should be entered into after December 31, 2021. The Alternative Reference 
Rates Committee (“ARRC”) has proposed that the Secured Overnight Financing Rate (“SOFR”) plus a spread that is based on 
historical data as the rate that represents the best practice as the alternative to USD-LIBOR for use in derivatives and other 
financial contracts that are currently indexed to USD-LIBOR. The intent of the LIBOR replacement rate is that it will not result 
in financial market disruptions, significant increases in benchmark rates, or financing costs to borrowers. The consequences of 
these developments cannot be entirely predicted, but could result in an increase in the cost of our variable rate debt.

While $150.0 million of our debt will become fixed rate debt beginning on January 1, 2024 as a result of our Forward Interest 
Rate Swaps, all of our debt is variable debt until such time. See Note 8 to our consolidated financial statements included in Part 
IV, Item 15(a) of this Annual Report on Form 10-K for further discussion.

The typical trading volume of our common stock may affect an investor’s ability to sell significant stock holdings in the 
future without negatively impacting stock price.

The level of trading activity may vary daily and typically represents only a small percentage of outstanding shares. As a result, a 
stockholder who sells a significant amount of shares in a short period of time could negatively affect our share price.

Our amount of debt may require us to raise additional capital to fund acquisitions.

We may sell additional shares of common stock or other equity securities to raise capital in the future, which could dilute the 
value of an investor’s holdings.

BUSINESS AND OPERATIONAL RISKS

Our end-use markets are cyclical.

We sell our products into aerospace, defense, and industrial end-use markets, which are cyclical and have experienced periodic 
declines. Our sales are, therefore, unpredictable and may tend to fluctuate based on a number of factors, including global 
economic conditions, geopolitical developments and conditions, pandemics, and other developments affecting our end-use 
markets and the customers served. Consequently, results of operations in any period should not be considered indicative of the 
operating results that may be experienced in any future period.

We depend upon a selected base of industries and customers, which subjects us to unique risks which may adversely 
affect us.

We currently generate a majority of our revenues from customers in the aerospace and defense industry. Our business depends, 
in part, on the level of new military and commercial aircraft orders. As a result, we have significant sales to certain customers. 
Sales to The Boeing Company (“Boeing”) and Spirit AeroSystems Holdings, Inc. (“Spirit”) comprise a significant portion of 
our commercial aerospace end-use market. A significant portion of our net sales in our military and space end-use markets are 
made under subcontracts with original equipment manufacturers (“OEMs”), under their prime contracts with the U. S. 
Government. We had significant sales to Lockheed Martin Corporation (“Lockheed Martin”), Northrop Grumman Corporation 
(“Northrop”), and Raytheon Technologies Corporation (“Raytheon”) in 2021 in our defense technologies end-use market.

Our customers may experience delays in the launch of new products, labor strikes, diminished liquidity or credit unavailability, 
weak demand for their products, or other difficulties in their business. In addition, shifts in government spending priorities have 
caused and may continue to cause additional uncertainty in the placement of orders.

Our revenues from our top ten customers, which represented 61% of our total 2021 net revenues, were diversified over a 
number of different aerospace and defense products. Any significant change in production rates by these customers would have 
a material effect on our results of operations and cash flows. There is no assurance that our current significant customers will 
continue to buy products from us at current levels, or that we will retain any or all of our existing customers, or that we will be 
able to form new relationships with customers upon the loss of one or more of our existing customers. This risk may be further 
complicated by pricing pressures, competition prevalent in our industry and other factors. A significant reduction in sales to any 
of our major customers, the loss of a major customer, or a default of a major customer on accounts receivable could have a 
material adverse impact on our financial results.

Boeing was one of our largest customers in 2021, and the 737 MAX was one of our highest commercial end use market revenue 
platforms. In late 2020, Boeing began receiving regulatory approval for its 737 MAX to return to service from some of the 
major civil aviation regulators around the world and thus, we began seeing a modest ramp up in our production rates during 
2021. Revenue growth with our other commercial customers and defense OEMs (also known as prime contractors) has helped 
to mitigate a significant portion of this risk for the time being. However, the COVID-19 pandemic continues to dampened civil 
air travel demand in many markets, and if traveler confidence does not return in the near future, it may make it difficult to 
continue to offset a significant portion of this risk.

We generally make sales under purchase orders and contracts that are subject to cancellation, modification or rescheduling. 
Changes in the economic environment and the financial condition of the industries we serve could result in customer 
cancellation of contractual orders or requests for rescheduling. Some of our contracts have specific provisions relating to 
schedule and performance, and failure to deliver in accordance with such provisions could result in cancellations, modifications, 
rescheduling and/or penalties, in some cases at the customers’ convenience and without prior notice. While we have normally 
recovered our direct and indirect costs plus profit, such cancellations, modifications, or rescheduling that cannot be replaced in 
a timely fashion, could have a material adverse effect on our financial results.

A significant portion of our business depends upon U.S. Government defense spending.

We derive a significant portion of our business from customers whose principal sales are to the U.S. Government. Accordingly, 
the success of our business depends upon government spending generally or for specific departments or agencies in particular. 
Such spending, among other factors, is subject to the uncertainties of governmental appropriations and national defense policies 
and priorities, constraints of the budgetary process, timing and potential changes in these policies and priorities, and the 
adoption of new laws or regulations or changes to existing laws or regulations.

These and other factors could cause the government and government agencies, or prime contractors that use us as a 
subcontractor, to reduce their purchases under existing contracts, to exercise their rights to terminate contracts for convenience 
or to abstain from exercising options to renew contracts, any of which could have a material adverse effect on our business, 
financial condition and results of operations.

13

Table of Contents

Further, the levels of U.S. Department of Defense (“U.S. DoD”) spending in future periods are difficult to predict and are 
impacted by numerous factors such as the political environment, U.S. foreign policy, macroeconomic conditions and the ability 
of the U.S. Government to enact relevant legislation such as the authorization and appropriations bills. The Budget Control Act 
(“2011 Act”) established limits on U.S. government discretionary spending, including a reduction of defense spending between 
the 2012 and 2021 U.S. Government fiscal years. Accordingly, long-term uncertainty remains with respect to overall levels of 
defense spending and it is likely that U.S. Government discretionary spending levels will continue to be subject to pressure.

Exports of certain of our products are subject to various export control regulations and authorizations, and we may not 
be successful in obtaining the necessary U.S. Government approvals and related export licenses for proposed sales to 
certain foreign customers.

We must comply with numerous laws and regulations relating to the export of some of our products before we are permitted to 
sell those products outside the United States. Compliance often entails the submission and timely receipt of the necessary export 
approvals, licenses, or authorizations from the U.S. Government. Over the last several years, the U.S. export licensing 
environment for munitions has been adversely affected by a number of factors, including, but not limited to, the changing 
geopolitical environment and heightened tensions with other countries (which shift and evolve over time). Accordingly, we can 
give no assurance that we will be successful in obtaining, in a timely manner or at all, the approvals, licenses or authorizations 
we need to sell our products outside the United States, which may result in the cancellation of orders and significant penalties to 
our customers if we do not make deliveries and fulfill our contractual commitments. Any significant delay in, or impairment of, 
our ability to sell products outside of the United States could have a material adverse effect on our business, financial condition 
and results of operations.

Contracts with some of our customers, including Federal government contracts, contain provisions which give our 
customers a variety of rights that are unfavorable to us and the OEMs to whom we provide products and services, 
including the ability to terminate a contract at any time for convenience.

Contracts with some of our customers, including Federal government contracts, contain provisions and are subject to laws and 
regulations that provide rights and remedies not typically found in commercial contracts. These provisions may allow our 
customers to:

•

•

•

•

terminate existing contracts, in whole or in part, for convenience, as well as for default, or if funds for contract 
performance for any subsequent year become unavailable;

terminate existing contracts if we are suspended or debarred from doing business with the federal government or 
with a governmental agency;

prohibit future procurement awards with a particular agency as a result of a finding of an organizational conflict of 
interest based upon prior related work performed for the agency that would give a contractor an unfair advantage 
over competing contractors; and

claim rights in products and systems produced by us.

If the U.S. Government terminates a contract for convenience, the counterparty with whom we have contracted on a subcontract 
may terminate its contract with us. As a result of any such termination, whether on a direct government contract or subcontract, 
we may recover only our incurred or committed costs, settlement expenses and profit on work completed prior to the 
termination. If the U.S. Government terminates a direct contract with us for default, we may not even recover those amounts 
and instead may be liable for excess costs incurred by the U.S. Government in procuring undelivered items and services from 
another source.

In addition, the U.S. Government is typically required to open all programs to competitive bidding and, therefore, may not 
automatically renew any of its prime contracts. If one or more of our customers’ government prime or subcontracts is 
terminated or canceled, our failure to replace sales generated from such contracts would result in lower sales and could have an 
adverse effect on our business, results of operations and financial condition.

Further consolidation in the aerospace industry could adversely affect our business and financial results.

The aerospace and defense industry is experiencing significant consolidation, including our customers, competitors and 
suppliers. Consolidation among our customers may result in delays in the awarding of new contracts and losses of existing 
business. Consolidation among our competitors may result in larger competitors with greater resources and market share, which 
could adversely affect our ability to compete successfully. Consolidation among our suppliers may result in fewer sources of 
supply and increased cost to us.

Our growth strategy includes evaluating selected acquisitions, which entails certain risks to our business and financial 
performance. 

We have historically achieved a portion of our growth through acquisitions and expect to evaluate selected future acquisitions 
as part of our strategy for growth. Any acquisition of another business entails risks and it is possible that we may not realize the 
expected benefits from an acquisition or that an acquisition could adversely affect our existing operations. Acquisitions entail 
certain risks, including:

•

•

•

•

•

difficulty in integrating the operations and personnel of the acquired company within our existing operations or in 
maintaining uniform standards;

loss of key employees or customers of the acquired company; 

the failure to achieve anticipated synergies;

unrecorded liabilities of acquired companies that we fail to discover during our due diligence investigations or that 
are not subject to indemnification or reimbursement by the seller; and 

management and other personnel having their time and resources diverted to evaluate, negotiate and integrate 
acquisitions. 

We may not be successful in achieving expected operating efficiencies and sustaining or improving operating expense 
reductions, and may experience business disruptions associated with restructuring, performance center consolidations, 
realignment, cost reduction, and other strategic initiatives.

In recent years, we have implemented a number of restructuring, realignment, and cost reduction initiatives, including 
performance center consolidations, organizational realignments, and reductions in our workforce. While we have realized some 
efficiencies from these actions, we may not realize the benefits of these initiatives to the extent we anticipated. Further, such 
benefits may be realized later than expected, and the ongoing difficulties in implementing these measures may be greater than 
anticipated, which could cause us to incur additional costs or result in business disruptions. In addition, if these measures are 
not successful or sustainable, we may have to undertake additional realignment and cost reduction efforts, which could result in 
significant additional charges. Moreover, if our restructuring and realignment efforts prove ineffective, our ability to achieve 
our other strategic and business plan goals may be adversely impacted.

As we move up the value chain to become a more value added supplier, enhanced design, product development, 
manufacturing, supply chain project management and other skills will be required.

We may encounter difficulties as we execute our growth strategy to move up the value chain to become a more value added 
supplier of more complex assemblies. Difficulties we may encounter include, but are not limited to, the need for enhanced and 
expanded product design skills, enhanced ability to control and influence our suppliers, enhanced quality control systems and 
infrastructure, enhanced large-scale project management skills, and expanded industry certifications. Assuming incremental 
project design responsibilities would require us to assume additional risk in developing cost estimates and could expose us to 
increased risk of losses. There can be no assurance that we will be successful in obtaining the enhanced skills required to move 
up the value chain or that our customers will outsource such functions to us.

Risks associated with operating and conducting our business outside the United States could adversely impact us.

We have manufacturing facilities in Thailand and Mexico and also derive a portion of our net revenues from direct foreign 
sales. Further, our customers may derive portions of their revenues from non-U.S. customers. As a result, we are subject to the 
risks of conducting and operating our business internationally, including:

•

•

•

•

•

•

•

political instability;

economic and geopolitical developments and conditions;

pandemics and disasters, natural or otherwise;

compliance with a variety of international laws, as well as U.S. laws affecting the activities of U.S. companies 
conducting business abroad, including, but not limited to, the Foreign Corrupt Practices Act;

imposition of taxes, export controls, tariffs, embargoes and other trade restrictions;

difficulties repatriating funds or restrictions on cash transfers; and

potential for new tariffs imposed on imports by the U.S. administration.

Table of Contents

While the impact of these factors is difficult to predict, we believe any one or more of these factors could have a material 
adverse effect on our financial results.

Customer pricing pressures could reduce the demand and/or price for our products and services.

The markets we serve are highly competitive and price sensitive. We compete worldwide with a number of domestic and 
international companies that have substantially greater manufacturing, purchasing, marketing and financial resources than we 
do. Many of our customers have the in-house capability to fulfill their manufacturing requirements. Our larger competitors may 
be able to compete more effectively for very large-scale contracts than we can by providing different or greater capabilities or 
benefits such as technical qualifications, past performance on large-scale contracts, geographic presence, price and availability 
of key professional personnel. If we are unable to successfully compete for new business, our net revenues growth and 
operating margins may decline.

Several of our major customers have completed extensive cost containment efforts and we expect continued pricing pressures in 
2022 and beyond. Competitive pricing pressures may have an adverse effect on our financial condition and operating results. 
Further, there can be no assurance that competition from existing or potential competitors in other segments of our business will 
not have a material adverse effect on our financial results. If we do not continue to compete effectively and win contracts, our 
future business, financial condition, results of operations and our ability to meet our financial obligations may be materially 
compromised.

Our products and processes are subject to risk of obsolescence as a result of changes in technology and evolving 
industry and regulatory standards.

The future success of our business depends in large part upon our and our customers’ ability to maintain and enhance 
technological capabilities, develop and market manufacturing services that meet changing customer needs and successfully 
anticipate or respond to technological advances in manufacturing processes on a cost-effective and timely basis, while meeting 
evolving industry and regulatory standards. To address these risks, we invest in product design and development, and incur 
related capital expenditures. There can be no guarantee that our product design and development efforts will be successful, or 
that funds required to be invested in product design and development or incurred as capital expenditures will not increase 
materially in the future.

We may not have the ability to renew facilities leases on terms favorable to us and relocation of operations presents risks 
due to business interruption.

Certain of our manufacturing facilities and offices are leased and have lease terms that expire between 2022 and 2031. The 
majority of these leases provide renewal options at the fair market rental rate at the time of renewal, which, if renewed, could be 
significantly higher than our current rental rates. We may be unable to offset these cost increases by charging more for our 
products and services. Furthermore, continued economic conditions may continue to negatively impact and create greater 
pressure in the commercial real estate market, causing higher incidences of landlord default and/or lender foreclosure of 
properties, including properties occupied by us. While we maintain certain non-disturbance rights in most cases, it is not certain 
that such rights will in all cases be upheld and our continued right of occupancy in such instances could be potentially 
jeopardized. An occurrence of any of these events could have a material adverse effect on our financial results.

Additionally, if we choose to move any of our operations, those operations may be subject to additional relocation costs and 
associated risks of business interruption.

LEGAL, REGULATORY, TAX, AND ACCOUNTING RISKS

We are subject to extensive regulation and audit by the Defense Contract Audit Agency.

The accuracy and appropriateness of certain costs and expenses used to substantiate our direct and indirect costs for the U.S. 
Government contracts are subject to extensive regulation and audit by the Defense Contract Audit Agency, an arm of the U.S. 
DoD. Such audits and reviews could result in adjustments to our contract costs and profitability. However, we cannot ensure the 
outcome of any future audits and adjustments may be required to reduce net sales or profits upon completion and final 
negotiation of audits. If any audit or review were to uncover inaccurate costs or improper activities, we could be subject to 
penalties and sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension 
or prohibition from conducting future business with the U.S. Government. Any such outcome could have a material adverse 
effect on our financial results.

16

Table of Contents

We are subject to a number of procurement laws and regulations. Our business and our reputation could be adversely 
affected if we fail to comply with these laws.

We must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. 
Government contracts. Government contract laws and regulations affect how we do business with our customers and impose 
certain risks and costs on our business. A violation of specific laws and regulations, by us, our employees, or others working on 
our behalf, such as a supplier or a venture partner, could harm our reputation and result in the imposition of fines and penalties, 
the termination of our contracts, suspension or debarment from bidding on or being awarded contracts, loss of our ability to 
export products or services and civil or criminal investigations or proceedings. 

In some instances, these laws and regulations impose terms or rights that are different from those typically found in commercial 
transactions. For example, the U.S. Government may terminate any of our customers’ government contracts and subcontracts 
either at its convenience or for default based on our performance. Upon termination for convenience of a fixed-price type 
contract, we normally are entitled to receive the purchase price for delivered items, reimbursement for allowable costs for work-
in-process and an allowance for profit on the contract or adjustment for loss if completion of performance would have resulted 
in a loss.

Our operations are subject to numerous extensive, complex, costly and evolving laws, regulations and restrictions, 
including cybersecurity requirements, and failure to comply with these laws, regulations and restrictions could subject 
us to penalties and sanctions that could harm our business.

Prime contracts with our major customers that have contracts with various agencies of the U.S. Government are subject to 
numerous laws and regulations, which affect how we do business with our customers and may impose added costs to our 
business. As a result, our contracts and operations are subject to numerous, extensive, complex, costly and evolving laws, 
regulations and restrictions, principally by the U.S. Government or their agencies. These laws, regulations and restrictions 
govern items including, but not limited to, the formation, administration and performance of U.S. Government contracts, 
disclosure of cost and pricing data, civil penalties for violations of false claims to the U.S. Government for payment, defining 
reimbursable costs, establishing ethical standards for the procurement process, controlling the import and export of defense 
articles and services, and cybersecurity requirements, such as Cybersecurity Maturity Model Certification (“CMMC”).

Noncompliance could expose us to liability for penalties, including termination of our contracts and subcontracts, 
disqualification from bidding on future U.S. Government contracts and subcontracts, suspension or debarment from U.S. 
Government contracting and various other fines and penalties. Noncompliance found by any one agency could result in fines, 
penalties, debarment or suspension from receiving additional contracts with all U.S. Government agencies. Given our 
dependence on U.S. Government business, suspension or debarment could have a material adverse effect on our financial 
results.

In addition, the U.S. Government may revise its procurement practices or adopt new contract rules and regulations, at any time, 
including increased usage of fixed-price contracts, procurement reform, and compliance with cybersecurity requirements. Such 
changes could impair our ability to obtain new contracts or subcontracts or renew contracts or subcontracts under which we 
currently perform when those contracts are put up for competitive bidding. Any new contracting methods could be costly or 
administratively difficult for us to implement and could adversely affect our future net revenues.

In addition, our international operations subject us to numerous U.S. and foreign laws and regulations, including, without 
limitation, regulations relating to import-export control, technology transfer restrictions, repatriation of earnings, exchange 
controls, the Foreign Corrupt Practices Act, and the anti-boycott provisions of the U.S. Export Administration Act. Changes in 
regulations or political environments may affect our ability to conduct business in foreign markets including investment, 
procurement and repatriation of earnings. Failure by us or our sales representatives or consultants to comply with these laws 
and regulations could result in certain liabilities and could possibly result in suspension or debarment from government 
contracts or suspension of our export privileges, which could have a material adverse effect on our financial results.

Environmental liabilities could adversely affect our financial results.

We are subject to various federal, local, and foreign environmental laws and regulations, including those relating to the use, 
storage, transport, discharge and disposal of hazardous and non-hazardous chemicals and materials used and emissions 
generated during our manufacturing process. We do not carry insurance for these potential environmental liabilities. Any failure 
by us to comply with present or future regulations could subject us to future liabilities or the suspension of production, which 
could have a material adverse effect on our financial results. Moreover, some environmental laws relating to contaminated sites 
can impose joint and several liability retroactively regardless of fault or the legality of the activities giving rise to the 
contamination. Compliance with existing or future environmental laws and regulations may require extensive capital 
expenditures, increase our cost or impact our production capabilities. Even if such expenditures are made, there can be no 
assurance that we will be able to comply. We have been directed to investigate and take corrective action for groundwater 

17

Table of Contents

contamination at certain sites and our ultimate liability for such matters will depend upon a number of factors. See Note 14 to 
our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further information.

The occurrence of litigation in which we could be named as a defendant is unpredictable.

From time to time, we and our subsidiaries are involved in various legal and other proceedings that are incidental to the conduct 
of our business. While we believe no current proceedings, if adversely determined, could have a material adverse effect on our 
financial results, no assurances can be given. Any such claims may divert financial and management resources that would 
otherwise be used to benefit our operations and could have a material adverse effect on our financial results. See Note 14 to our 
consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further information.

Product liability claims in excess of insurance could adversely affect our financial results and financial condition.

We face potential liability for property damage, personal injury, or death as a result of the failure of products designed or 
manufactured by us. Although we currently maintain product liability insurance (including aircraft product liability insurance), 
any material product liability not covered by insurance could have a material adverse effect on our financial condition, results 
of operations and cash flows.

We use estimates when bidding on fixed-price contracts. Changes in our estimates could adversely affect our financial 
results.

We enter into contracts providing for a firm, fixed-price for the sale of a majority of our products, regardless of the production 
costs incurred by us. In many cases, we make multi-year firm, fixed-price commitments to our customers, without assurance 
that our anticipated production costs will be achieved. Contract bidding and accounting require judgment relative to assessing 
risks, estimating contract net sales and costs, including estimating cost increases over time and efficiencies to be gained, and 
making assumptions for supplier sourcing and quality, manufacturing scheduling and technical issues over the life of the 
contract. Such assumptions can be particularly difficult to estimate for contracts with new customers. Inaccurate estimates of 
these costs could result in reduced profits or incurred losses. Due to the significance of the judgments and estimates involved, it 
is possible that materially different amounts could be obtained if different assumptions were used or if the underlying 
circumstances were to change. Therefore, any changes in our underlying assumptions, circumstances or estimates could have a 
material adverse effect on our financial results. 

Goodwill and/or other assets could be impaired in the future, which could result in substantial charges.

Goodwill is tested for impairment on an annual basis as of the first day of our fourth quarter or more frequently if events or 
circumstances occur which could indicate potential impairment. In assessing the recoverability of goodwill, management is 
required to make certain critical estimates and assumptions. These estimates and assumptions include projected sales levels, 
including the addition of new customers, programs or platforms and increased content on existing programs or platforms, 
improvements in manufacturing efficiency, and reductions in operating costs. Due to many variables inherent in the estimation 
of a business’s fair value and the relative size of our recorded goodwill, changes in estimates and assumptions may have a 
material effect on the results of our impairment analysis. If any of these or other estimates and assumptions are not realized in 
the future, or if market multiples decline, we may be required to record an impairment charge for goodwill. 

We also test intangible assets with indefinite life periods for potential impairment annually and on an interim basis if there are 
indicators of potential impairment. 

In addition, we evaluate amortizable intangible assets, fixed assets, production cost of contracts, and lease right-of-use assets for 
impairment if there are indicators of a potential impairment. 

Further, impairment charges may be incurred against other intangible assets or long-term assets if asset utilization declines, 
customer demand declines or other circumstances indicate that the asset carrying value may not be recoverable. 

Our goodwill and other intangible assets as of December 31, 2021 were $345.5 million, or 35% of total assets. If our goodwill 
and/or other assets are impaired, it could have an adverse effect on our results of operations and financial condition. See 
“Goodwill and Indefinite-Lived Intangible Assets” in Note 6 of our consolidated financial statements included in Part IV, 
Item 15(a) of this Form 10-K for further information.

Unanticipated changes in our tax provision or exposure to additional income tax liabilities could affect our profitability.

Significant judgment is required in determining our provision for income taxes. In the ordinary course of our business, there are 
transactions and calculations where the ultimate tax determination is uncertain. Furthermore, changes in income tax laws and 
regulations, or their interpretation, could result in higher or lower income tax rates assessed or changes in the taxability of 

18

Table of Contents

certain sales or the deductibility of certain expenses, thereby affecting our income tax expense and profitability. For example, 
we recorded provisional estimates of the impact of the Tax Cuts and Jobs Act (the “2017 Tax Act”) enacted in December 2017 
in accordance with SEC Staff Accounting Bulletin No. 118 (“SAB 118”) in our 2017 consolidated financial statements. During 
2018, these estimates were subject to further analysis and review which could have required adjustments, but no adjustments 
were required to be made in 2018. In addition, we are regularly under audit by tax authorities. The final determination of tax 
audits and any related litigation could be materially different from our historical income tax provisions and accruals.

Our ability to accurately report our financial results or prevent fraud may be adversely affected if our internal control 
over financial reporting is not effective.

The accuracy of our financial reporting is dependent on the effectiveness of our internal controls. We are required to provide a 
report from management to our shareholders on our internal control over financial reporting that includes an assessment of the 
effectiveness of these controls. Internal control over financial reporting has inherent limitations, including human error, the 
possibility that controls could be circumvented or become inadequate as a result of changed conditions, and fraud. Due to these 
inherent limitations, internal control over financial reporting might not prevent or detect all misstatements or fraud. If we cannot 
maintain and execute adequate internal control over financial reporting or implement required new or improved controls that 
provide reasonable assurance of the reliability of the financial reporting and preparation of our financial statements for external 
use, our ability to accurately report our financial results or prevent fraud could be adversely affected.

LABOR AND SUPPLY CHAIN RISKS

We are dependent upon our ability to attract and retain key personnel.

Our success depends in part upon our ability to attract and retain key engineering, technical and managerial personnel, at both 
the executive and performance center level. We face competition for management, engineering and technical personnel from 
other companies and organizations. The loss of members of our senior management group, or key engineering and technical 
personnel, could negatively impact our ability to grow and remain competitive in the future and could have a material adverse 
effect on our financial results.

Labor disruptions by our employees could adversely affect our business.

As of December 31, 2021, we employed 2,480 people. Two of our performance centers are parties to collective bargaining 
agreements, covering 145 full time hourly employees in one of those performance centers and 320 full time hourly employees 
in the other performance center, and will expire in June 2024 and April 2022, respectively. Although we have not experienced 
any material labor-related work stoppage and consider our relations with our employees to be good, labor stoppages may occur 
in the future. If the unionized workers were to engage in a strike or other work stoppage, if we are unable to negotiate 
acceptable collective bargaining agreements with the unions or if other employees were to become unionized, we could 
experience a significant disruption of our operations, higher ongoing labor costs and possible loss of customer contracts, which 
could have an adverse effect on our business and results of operations.

We rely on our suppliers to meet the quality and delivery expectations of our customers.

Our ability to deliver our products and services on schedule and to satisfy specific quality levels is dependent upon a variety of 
factors, including execution of internal performance plans, availability of raw materials, internal and supplier produced parts 
and structures, conversion of raw materials into parts and assemblies, and performance of suppliers and others.

We rely on numerous third-party suppliers for raw materials and a large proportion of the components used in our production 
process. Certain of these raw materials and components are available only from single sources or a limited number of suppliers, 
or similarly, customers’ specifications may require us to obtain raw materials and/or components from a single source or certain 
suppliers. Many of our suppliers are small companies with limited financial resources and manufacturing capabilities. We do 
not currently have the ability to manufacture these components ourselves. These and other factors, including the impact from 
the COVID-19 pandemic, import tariffs, the loss of a critical supplier or raw materials and/or component shortages, could cause 
disruptions or cost inefficiencies in our operations. Additionally, our competitors that have greater direct purchasing power, 
may have product cost advantages which could have a material adverse effect on our financial results.

GENERAL RISKS

The COVID-19 pandemic has had, and continues to have, a material adverse effect on our business, results of 
operations, and financial condition.

The COVID-19 pandemic has caused, and continues to cause, a significant adverse impact on our employees, operations, 
businesses of our customers, suppliers and distribution partners, and volatility in the financial markets. Changes in our 
operations in response to the COVID-19 pandemic or employee illnesses resulting from the pandemic, has resulted in and may 
continue to result in inefficiencies or delays, including in sales and product development efforts and our manufacturing and 
supply chain, and additional costs related to business continuity initiatives, that cannot be fully mitigated through succession 
planning, employees working remotely, or teleconferencing technologies. The long-term impact to our business remains 
unknown. This is due to the numerous uncertainties that have risen from the pandemic, including the severity of the disease, the 
duration of the outbreak, the likelihood of resurgences of the outbreak, including the emergence and spread of variants, actions 
that may be taken by governmental authorities in response to the disease, the timing, distribution, efficacy and public 
acceptance of vaccines, and the related unintended or unanticipated consequences. 

The commercial aerospace industry, in particular, has been significantly disrupted, both domestically and internationally, by the 
pandemic. The pandemic has resulted in governments around the world implementing stringent measures to help control the 
spread of the virus, including quarantines, shelter in place or stay at home orders, travel restrictions, business curtailments and 
other measures. As a result, demand for travel declined at a rapid pace beginning in mid-2020 and has remained below pre-
pandemic levels. However, commercial air travel has increasingly shown signs of recovery in recent months with increasing air 
traffic, primarily in certain domestic markets. The recovery in international commercial air travel has been slower with 
international travel still near the COVID-19 pandemic lows. The exact pace and timing of the commercial air travel recovery 
remains uncertain and is expected to continue to be uneven depending on factors such as trends in the number of COVID-19 
infections (i.e., impact of new variants of COVID-19 surfacing), the timing, distribution, efficacy, and public acceptance of 
vaccines, and easing of quarantines and travel restrictions, among other factors. While the full extent and impact of the 
COVID-19 pandemic cannot be reasonably estimated with certainty at this time, COVID-19 has had a significant impact on our 
business, the businesses of our customers and suppliers, as well as our results of operations and financial condition, and may 
have a material adverse impact on our business, results of operations and financial condition in 2022 and beyond.

Our ability to continue to manufacture products is highly dependent on our ability to maintain the safety and health of our 
performance center employees. While we are following the guidelines and requirements of governmental authorities and taking 
preventive and protective measures to prioritize the safety and well-being of our employees, these measures are not always 
successful. Thus far, the ability of our employees to work has not been significantly impacted by individuals contracting or 
being exposed to COVID-19. However, if an outbreak of COVID-19 or other viruses does occur at any of our performance 
centers, it may disrupt our ability to manufacture products and thus, have a material and adverse impact on our business, 
financial condition, and results of operations.

Increased scrutiny from investors, lenders, and other market participants regarding our environmental, social, and 
governance, or sustainability responsibilities could expose us to additional costs and adversely impact our liquidity, 
results of operations, reputation, employee retention, and stock price.

There is an increasing focus from certain investors, customers, and other key stakeholders concerning corporate responsibility, 
specifically related to environmental, social, and governance (“ESG”) factors. Some investors may use ESG criteria to guide 
their investment strategies and, in some cases, may choose not to invest in us if they believe our policies relating to corporate 
responsibilities are inadequate.

The ESG factors by which companies’ corporate responsibility practices are assessed may change. This could result in greater 
expectations of us and cause us to undertake costly initiatives to satisfy such new criteria. If we are unable to satisfy the new 
corporate responsibility criteria, investors may view our policies related to corporate responsibility as inadequate. We risk 
damage to our reputation in the event our corporate responsibility procedures or goals do not meet the standards or goals set by 
various constituencies. In addition, if our competitors’ corporate responsibility performance is perceived to be greater than ours, 
potential or current investors may elect to invest in our competitors instead. Further, in the event we communicate certain 
initiatives or goals related to ESG, we could fail, or be perceived to have failed, in our achievement of such initiatives or goals. 
If we fail to satisfy the expectations of investors and other key stakeholders, or our initiatives are not executed as planned, our 
reputation, employee retention, and willingness of our customers and suppliers to do business with us, financial results, and 
stock price could be materially and adversely affected.

20

Table of Contents

Cybersecurity attacks, internal system or service failures may adversely impact our business and operations.

Any system or service disruptions, including those caused by projects to improve our information technology systems, if not 
anticipated and appropriately mitigated, could disrupt our business and impair our ability to effectively provide products and 
related services to our customers and could have a material adverse effect on our business. We could also be subject to systems 
failures, including network, software or hardware failures, whether caused by us, third-party service providers, intruders or 
hackers, computer viruses, natural disasters, power shortages or terrorist attacks. Cybersecurity threats are evolving and include, 
but are not limited to, malicious software, unauthorized attempts to gain access to sensitive, confidential or otherwise protected 
information related to us or our products, our employees, customers or suppliers, or other acts that could lead to disruptions in 
our business. Any such failures could cause loss of data and interruptions or delays in our business, cause us to incur 
remediation costs, subject us to claims and damage our reputation. In addition, the failure or disruption of our communications 
or utilities could cause us to interrupt or suspend our operations or otherwise adversely affect our business. Our property and 
business interruption insurance may be inadequate to compensate us for all losses that may occur as a result of any system or 
operational failure or disruption which would adversely affect our business, results of operations and financial condition.

Assertions by third parties that we violated their intellectual property rights could have a material adverse effect on our 
business, financial condition, and results of operations.

Third parties may claim that we, our customers, licensees, or parties indemnified by us are infringing upon or otherwise 
violating their intellectual property rights. Such claims may be made by competitors seeking to obtain a competitive advantage 
or by other parties. Additionally, in recent years, individuals and groups have begun purchasing intellectual property assets for 
the purpose of making claims of infringement and attempting to extract settlements from companies like ours.

Any claims that we violated a third party’s intellectual property rights can be time consuming and costly to defend and distract 
management’s attention and resources, even if the claims are without merit. Such claims may also require us to redesign 
affected products and services, enter into costly settlement or license agreements or pay costly damage awards, or face a 
temporary or permanent injunction prohibiting us from marketing or providing the affected products and services. Even if we 
have an agreement to indemnify us against such costs, the indemnifying party may not have sufficient financial resources or 
otherwise be unable to uphold its contractual obligations. If we cannot or do not license the infringed technology on favorable 
terms or cannot or do not substitute similar technology from another source, our revenue and earnings could be adversely 
impacted.

Damage or destruction of our facilities caused by storms, earthquake, fires or other causes could adversely affect our 
financial results and financial condition.

We have operations located in regions of the U.S. that may be exposed to damaging storms, earthquakes, fires and other natural 
disasters. Although we maintain standard property casualty insurance covering our properties and may be able to recover costs 
associated with certain natural disasters through insurance, we do not carry any earthquake insurance because of the cost of 
such insurance. Many of our properties are located in Southern California, an area subject to earthquake activity. Our California 
performance centers generated $176.9 million in net revenues during 2021. Even if covered by insurance, any significant 
damage or destruction of our facilities due to storms, earthquakes, fires or other natural disasters could result in our inability to 
meet customer delivery schedules and may result in the loss of customers and significant additional costs to us. Thus, any 
significant damage or destruction of our properties could have a material adverse effect on our business, financial condition or 
results of operations. See discussion of a fire in June 2020 which severely damaged our Guaymas, Mexico performance center 
in Note 14 to our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further information.

Overview

Ducommun Incorporated (“Ducommun,” “the Company,” “we,” “us” or “our”) is a leading global provider of engineering and 
manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace, 
defense, industrial, medical, and other industries. We differentiate ourselves as a full-service solution-based provider, offering a 
wide range of value-added products and services in our primary businesses of electronics, structures and integrated solutions. 
We operate through two primary business segments:  Electronic Systems and Structural Systems, each of which is a reportable 
segment.

COVID-19 Pandemic Impact on Our Business

The COVID-19 pandemic has had a significant impact on our overall business during the year ended December 31, 2021. As a 
result of the COVID-19 pandemic, precautionary measures were instituted by governments and businesses to mitigate its 
spread, including the imposition of travel restrictions, quarantines, shelter in place directives, and shutting down of non-
essential businesses. 

The safety of our employees remains our highest priority. The well-being and safety protocols that were already in place at all 
of our facilities were further enhanced at the onset of the COVID-19 pandemic. We continue to follow safety protocols 
consistent with guidelines provided by state and local governments and the Centers for Disease Control and Prevention 
(“CDC”). These measures included social distancing, provision of personal protective equipment, enhanced cleaning, and 
flexible work arrangements wherever possible. We have also offered enhanced leave and benefits to our employees and 
provided frequent updates to ensure our workforce continues to be kept apprised of evolving regulations and safety measures.

In March 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which provides tax 
relief to individuals and businesses affected by the coronavirus pandemic. We have not requested or accepted any loans or 
payments that are available under the CARES Act, however, we have utilized the option to defer payment of the employer 
portion of payroll taxes (Social Security) that would otherwise be required to be made during the period beginning March 27, 
2020 to December 31, 2020. One half of the deferred amount was required to be paid and was paid by December 31, 2021, with 
the remaining 50% to be paid by December 31, 2022. As of December 31, 2021, our remaining deferred amount is $3.1 million 
and is included as part of accrued and other liabilities on the consolidated balance sheets.

The COVID-19 pandemic has and continues to contribute to a general slowdown in the global economy and most significantly, 
the commercial aerospace end-use market. While both major large aircraft manufacturers, The Boeing Company (“Boeing”) 
and Airbus SE, have announced increases in build rates for 2022, it is well below pre-pandemic levels. In its 2021 Annual 
Report on Form 10-K, Boeing indicated it expects commercial air travel to return to 2019 levels in 2023 to 2024, and a few 
years beyond that for the industry to return to the long-term trend growth. While the full extent and impact of the COVID-19 
pandemic cannot be reasonably estimated with certainty at this time, COVID-19 has had a significant impact on our business, 
the businesses of our customers and suppliers, as well as our results of operations and financial condition, and may have a 
material adverse impact on our business, results of operations and financial condition for 2022 and beyond. See Risk Factors 
included in Part I, Item 1A of this Annual Report on Form 10-K (“Form 10-K”).

Recap for the year ended December 31, 2021:

•

•

Net revenues of $645.4 million 

Net income of $135.5 million, or $11.06 per diluted share

Adjusted EBITDA of $92.8 million

Non-GAAP Financial Measures

Adjusted earnings before interest, taxes, depreciation, amortization, stock-based compensation expense, Guaymas fire related 
expenses, gain on sale-leaseback, success bonus related to the completion of sale-leaseback transaction, inventory purchase 
accounting adjustments, restructuring charges, loss on extinguishment of debt, and other debt refinancing costs (“Adjusted 
EBITDA”) was $92.8 million and $87.9 million for years ended December 31, 2021 and December 31, 2020, respectively.

When viewed with our financial results prepared in accordance with accounting principles generally accepted in the United 
States of America (“GAAP”) and accompanying reconciliations, we believe Adjusted EBITDA provides additional useful 
information to clarify and enhance the understanding of the factors and trends affecting our past performance and future 
prospects. We define Adjusted EBITDA, explain how it is calculated, and provide a reconciliation to the most comparable 
GAAP measure in the table below. Adjusted EBITDA and the related financial ratios, as presented in this Annual Report on 

24

Table of Contents

Form 10-K (“Form 10-K”), are supplemental measures of our performance that are not required by, or presented in accordance 
with, GAAP. They are not a measurement of our financial performance under GAAP and should not be considered as 
alternatives to net income or any other performance measures derived in accordance with GAAP, or as an alternative to net cash 
provided by operating activities as measures of our liquidity. The presentation of these measures should not be interpreted to 
mean that our future results will be unaffected by unusual or nonrecurring items.

We use Adjusted EBITDA non-GAAP operating performance measures internally as complementary financial measures to 
evaluate the performance and trends of our businesses. We also present Adjusted EBITDA and the related financial ratios, as 
applicable, because we believe that measures such as these provide useful information with respect to our ability to meet our 
operating commitments.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as substitutes for analysis 
of our results as reported under GAAP. Some of these limitations include:

•

•

•

•

•

•

•

It does not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments;

It does not reflect changes in, or cash requirements for, our working capital needs;

It does not reflect the significant interest expense or the cash requirements necessary to service interest or 
principal payments on our debt;

Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will 
often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such 
replacements;

It is not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows;

It does not reflect the impact on earnings or charges resulting from matters unrelated to our ongoing operations; 
and

Other companies in our industry may calculate Adjusted EBITDA differently from us, limiting their usefulness as 
comparative measures.

As a result of these limitations, Adjusted EBITDA and the related financial ratios should not be considered as measures of 
discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to us to 
meet our obligations. You should compensate for these limitations by relying primarily on our GAAP results and using 
Adjusted EBITDA only as supplemental information. See our consolidated financial statements contained in this Form 10-K.

Even with the limitations above, we believe that Adjusted EBITDA is useful to an investor in evaluating our results of 
operations as this measure:

•

•

•

Is widely used by investors to measure a company’s operating performance without regard to items excluded from 
the calculation of such terms, which can vary substantially from company to company depending upon accounting 
methods and book value of assets, capital structure and the method by which assets were acquired, among other 
factors;

Helps investors to evaluate and compare the results of our operations from period to period by removing the effect 
of our capital structure from our operating performance; and

Is used by our management team for various other purposes in presentations to our Board of Directors as a basis 
for strategic planning and forecasting.

The following financial items have been added back to or subtracted from our net income when calculating Adjusted EBITDA:

•

•

•

•

•

•

Interest expense may be useful to investors for determining current cash flow;

Income tax expense may be useful to investors because it represents the taxes which may be payable for the period 
and the change in deferred taxes during the period, and may reduce cash flow available for use in our business;

Depreciation may be useful to investors because it generally represents the wear and tear on our property and 
equipment used in our operations;

Amortization expense may be useful to investors because it represents the estimated attrition of our acquired 
customer base and the diminishing value of product rights;

Stock-based compensation expense may be useful to our investors for determining current cash flow;

Guaymas fire related expenses may be useful to our investors in evaluating our core operating performance;

•

Gain on sale-leaseback may be useful to our investors in evaluating our core operating performance;

Success bonus related to completion of sale-leaseback transaction may be useful to our investors in evaluating our 
core operating performance;

Purchase accounting inventory step-ups may be useful to our investors as they do not necessarily reflect the 
current or on-going cash charges related to our core operating performance;

Restructuring charges may be useful to our investors in evaluating our core operating performance;

Loss on extinguishment of debt may be useful to our investors for determining current cash flow; and

Other debt refinancing costs may be useful to our investors in evaluating our core operating performance.

Net revenues for 2021 were $645.4 million compared to $628.9 million for 2020. The year-over-year increase was primarily 
due to the following:

•

$31.0 million higher revenues in our military and space end-use markets due to higher build rates on military 
fixed-wing aircraft platforms and higher build rates on various missile platforms; partially offset by

(1) Includes The Boeing Company (“Boeing”), Lockheed Martin Corporation (“Lockheed Martin”), Northrop Grumman

The revenues from Boeing, Lockheed Martin, Northrop, and Raytheon are diversified over a number of commercial, military 
and space programs and were generated by both operating segments.

Gross Profit

Gross profit consists of net revenues less cost of sales. Cost of sales includes the cost of production of finished products and 
other expenses related to inventory management, manufacturing quality, and order fulfillment. Gross profit margin increased to 
22.1% in 2021 compared to 21.9% in 2020 primarily due to favorable product mix and lower other manufacturing costs.

Selling, General and Administrative (“SG&A”) Expenses

SG&A expenses increased $3.8 million in 2021 compared to 2020 primarily due to higher professional services fees of $2.2 
million, a portion of which was related to the MagSeal acquisition, and higher compensation and benefits costs of $1.6 million.

Restructuring Charges

Restructuring charges decreased $2.4 million in 2021 compared to 2020 primarily due to the 2020 restructuring plan being 
completed by the end of 2020. See Note 1 to our consolidated financial statements included in Part IV, Item 15(a) of this 
Annual Report on Form 10-K for further information on restructuring activities.

Interest Expense

Interest expense decreased in 2021 compared to 2020 primarily due to a lower amount of debt outstanding and lower interest 
rates. See Note 8 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K 
for further information on our long-term debt.

Gain on Sale-Leaseback

Gain on sale-leaseback increased in 2021 compared to 2020 due to the Gardena performance center located in Carson, 
California, sale-leaseback transaction we entered into on December 16, 2021. See Note 5 to our consolidated financial 
statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K for further information on our sale-leaseback 
transaction.

Income Tax Expense
We recorded an income tax expense of $34.9 million (an effective tax rate of 20.5%) in 2021, compared to $2.8 million (an 
effective tax rate of 8.8%) in 2020. The increase in the effective tax rate for 2021 compared to 2020 was primarily due to higher 
pre-tax income for 2021, which included the gain on the sale-leaseback transaction we entered into on December 16, 2021, 
compared to 2020. The higher pre-tax income in 2021 caused the research and development tax credits to have a lower income 
tax benefit impact on the effective tax rate. The increase in the effective tax rate was also due to lower discrete income tax 
benefits recognized from the release of uncertain tax positions in 2021 compared to 2020. 

Our unrecognized tax benefits were $4.4 million and $4.1 million in 2021 and 2020, respectively. We record interest and 
penalty charges, if any, related to uncertain tax positions as a component of tax expense and unrecognized tax benefits. The 
amounts accrued for interest and penalty charges as of December 31, 2021 and 2020 were not significant. If recognized, $2.6 

28

Table of Contents

million would affect the effective income tax rate. As a result of statute of limitations set to expire in 2022, we expect decreases 
to our unrecognized tax benefits of approximately $0.7 million in the next twelve months.

We file U.S. Federal and state income tax returns. We are subject to examination by the Internal Revenue Service (“IRS”) for 
tax years after 2017 and by state taxing authorities for tax years after 2016. While we are no longer subject to examination prior 
to those periods, carryforwards generated prior to those periods may still be adjusted upon examination by the IRS or state 
taxing authority if they either have been or will be used in a subsequent period. We believe we have adequately accrued for tax 
deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.

In March 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) that provided tax 
relief to individuals and businesses affected by the coronavirus pandemic. We considered the provisions of the CARES Act and 
determined they do not have a material impact to our overall income taxes. We utilized the option to defer payment of the 
employer portion of payroll taxes (Social Security) that would otherwise be required to be made during the period beginning 
March 27, 2020 to December 31, 2020. See COVID-19 Pandemic Impact on Our Business included in Part II, Item 7 of this 
Form 10-K. As such, as of December 31, 2020, we deferred payment of income tax deductions related to payroll taxes of 
$6.1 million and recorded the related deferred tax asset of $1.4 million, which was included as part of the net deferred income 
taxes on the consolidated balance sheet. We were required to and made the payments for 50% of the deferred payroll taxes by 
December 31, 2021. As of December 31, 2021, the remaining unpaid deferred income tax deductions related to payroll taxes is 
$3.1 million and the related deferred tax asset of $0.7 million is included as part of the net deferred income taxes on the 
consolidated balance sheet.

In December 2020, the U.S. enacted the Consolidated Appropriations Act, 2021 (the “Appropriations Act”) that provided 
additional tax relief to individuals and businesses affected by the coronavirus pandemic. We considered the provisions of the 
Appropriations Act and determined they do not have a material impact to our overall income taxes.

On March 11, 2021, the U.S. enacted the American Rescue Plan Act of 2021 (“Rescue Plan”). The amendment to Section 
162(m) expanding the definition of covered employee to also include the next five highest compensated employees in the 
limitation will apply to us effective January 1, 2027. We do not expect any tax impacts to be material. We considered other 
provisions in the Rescue Plan and determined they have no or minimal impact to our overall income taxes.

The Tax Cuts and Jobs Act of 2017 (“TCJA”), which was signed into U.S. law in December 2017, eliminated the option to 
immediately deduct research and development expenditures in the year incurred under Section 174 effective January 1, 2022. 
The amended provision under Section 174 requires us to capitalize and amortize these expenditures over five years. Although 
there is proposed legislation to temporarily reinstate the current deduction of the expenditures after 2021 through 2025, we must 
consider the changes under the TCJA. If the provision is not deferred, modified, or repealed, with retroactive effect to January 
1, 2022, it may result in a material impact on cash from operating activities and the balance of our deferred taxes. The actual 
impact will depend on if and when this provision is deferred, modified, or repealed by Congress, including if retroactively to 
January 1, 2022, and the amount of research and development expenditures incurred in 2022. We are monitoring legislation for 
any further changes to Section 174 and the impact to the financial statements in 2022.

Net Income and Earnings per Diluted Share

Net income and earnings per diluted share for 2021 were $135.5 million, or $11.06 per diluted share, compared to net income 
and earnings per diluted share for 2020 of $29.2 million, or $2.45 per diluted share. The increase in net income in 2021 
compared to 2020 was primarily due to a gain on sale-leaseback of $132.5 million, $4.7 million of higher gross profit as a result 
of higher revenues, lower interest expense of $2.5 million, and lower restructuring charges of $2.4 million, partially offset by 
higher income tax expense of $32.1 million and higher SG&A expenses of $3.8 million.

Business Segment Performance

We report our financial performance based upon the two reportable operating segments: Electronic Systems and Structural 
Systems. The results of operations differ between our reportable operating segments due to differences in competitors, 
customers, extent of proprietary deliverables and performance. The following table summarizes our business segment 
performance for 2021 and 2020:

Electronic Systems

Electronic Systems’ net revenues in 2021 compared to 2020 increased $20.0 million primarily due to the following:

•

•

$19.2 million higher revenues in our military and space end-use markets due to higher build rates on military 
fixed-wing aircraft platforms, partially offset by lower build rates on various missile platforms; and

$2.9 million higher revenues in our commercial aerospace end-use markets due to higher build rates on other 
commercial aerospace platforms.

Electronic Systems segment operating income in 2021 compared to 2020 increased $5.7 million primarily due to favorable 
product mix and lower other manufacturing costs.

Structural Systems

Structural Systems’ net revenues in 2021 compared to 2020 decreased $3.5 million primarily due to the following:

•

•

$15.3 million lower revenues in commercial aerospace end-use markets due to lower build rates on large aircraft 
platforms; partially offset by

$11.8 million higher revenues in military and space end-use markets due to higher build rates on various missile 
platforms.

The Structural Systems operating income in 2021 compared to 2020 increased $0.7 million primarily due to lower other 
manufacturing costs, partially offset by unfavorable product mix.

In June 2020, a fire severely damaged our performance center in Guaymas, Mexico, which is part of our Structural Systems 
segment. There were no injuries, however, property and equipment, inventory, and tooling in this leased facility were damaged. 
We have insurance coverage and expect the majority, if not all, of these items will be covered, less our deductible. The full 
financial impact cannot be estimated at this time as we are currently working with our insurance carriers to determine the cause 
of the fire. Our Guaymas performance center is comprised of two buildings with an aggregate total of 62,000 square feet. The 
loss of production from the Guaymas performance center is being absorbed by our other existing performance centers. See 
Note 14 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K for 
additional information.

Corporate General and Administrative (“CG&A”) Expenses

CG&A expenses in 2021 compared to 2020 increased $3.0 million primarily due to higher professional services fees of $1.9 
million, a portion of which was related to the acquisition of MagSeal, and higher compensation and benefits costs of $1.8 
million.

Backlog

We define backlog as customer placed purchase orders (“POs”) and long-term agreements (“LTAs”) with firm fixed price and 
expected delivery dates of 24 months or less. The majority of the LTAs do not meet the definition of a contract under ASC 606 
and thus, the backlog amount disclosed below is greater than the remaining performance obligations amount disclosed in Note 1 
to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K. Backlog is subject 
to delivery delays or program cancellations, which are beyond our control. Backlog is affected by timing differences in the 
placement of customer orders and tends to be concentrated in several programs to a greater extent than our net revenues. 
Backlog in industrial markets tends to be of a shorter duration and is generally fulfilled within a three month period. As a result 
of these factors, trends in our overall level of backlog may not be indicative of trends in our future net revenues.

The increase in backlog was primarily in the commercial aerospace end-use markets and industrial end-use markets. $628.0 
million of total backlog is expected to be delivered over the next 12 months. The following table summarizes our backlog for

In December 2019, we completed the refinancing of a portion of our existing debt by entering into a new revolving credit 
facility (“2019 Revolving Credit Facility”) to replace the existing revolving credit facility that was entered into in November 
2018 (“2018 Revolving Credit Facility”) and entering into a new term loan (“2019 Term Loan”). The 2019 Revolving Credit 
Facility is a $100.0 million senior secured revolving credit facility that will mature on December 20, 2024 replacing the $100.0 
million 2018 Revolving Credit Facility that would have matured on November 21, 2023. The 2019 Term Loan is a $140.0 
million senior secured term loan that will mature on December 20, 2024. We also have an existing $240.0 million senior 
secured term loan that was entered into in November 2018 that will mature on November 21, 2025 (“2018 Term Loan”). The 
original amounts available under the 2019 Revolving Credit Facility, 2019 Term Loan, and 2018 Term Loan (collectively, the 
“Credit Facilities”) in aggregate, totaled $480.0 million. We are required to make installment payments of 1.25% of the original 
outstanding principal balance of the 2019 Term Loan amount on a quarterly basis, on the last day of the calendar quarter and 
thus, paid $7.0 million during 2021. In addition, if we meet the annual excess cash flow threshold, we are required to make an 
annual additional principal payment based on the consolidated adjusted leverage ratio. During the first quarter of 2021, we 
made the required 2020 annual excess cash flow payment of $0.9 million. Further, the undrawn portion of the commitment of 
the 2019 Revolving Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the 

32

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

consolidated total net adjusted leverage ratio. As of December 31, 2021, we were in compliance with all covenants required 
under the Credit Facilities. See Note 8 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual 
Report on Form 10-K for further information.

We drew down $50.0 million on the 2019 Revolving Credit Facility during the first quarter of 2020 to hold as cash on hand, 
$25.0 million of which was repaid during the fourth quarter of 2020 with the remaining $25.0 million repaid during 2021, thus, 
we made no net aggregate voluntary prepayments during 2021.

In November 2018, we completed credit facilities to replace the then existing credit facilities. The November 2018 credit 
facilities consisted of the 2018 Term Loan and the 2018 Revolving Credit Facility (collectively, the “2018 Credit Facilities”). 
We were required to make installment payments of 0.25% of the outstanding principal balance of the 2018 Term Loan amount 
on a quarterly basis, however, in conjunction with the 2019 refinancing where we paid down $56.0 million on the 2018 Term 
Loan, it paid all the required quarterly installment payments on the 2018 Term Loan until maturity.

On November 29, 2021, we entered into derivative contracts, U.S. dollar-one month LIBOR forward interest rate swaps 
designated as cash flow hedges, all with an effective date of January 1, 2024, for an aggregate total notional amount of $150.0 
million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 (“Forward Interest Rate Swaps”). The 
Forward Interest Rate Swaps mature on a monthly basis, with fixed amount payer payment dates on the first day of each 
calendar month, commencing on February 1, 2024 through January 1, 2031. See Note 1 and Note 8 to our consolidated 
financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K for further information.

In October 2015, we entered into interest rate cap hedges designated as cash flow hedges with a portion of these interest rate 
cap hedges maturing on a quarterly basis, and a final quarterly maturity date of June 2020, in aggregate, totaling $135.0 million 
of our debt. We paid a total of $1.0 million in connection with entering into the interest rate cap hedges. The interest rate cap 
hedges matured during our second quarter of 2020 and as such, all remaining amounts related to the interest rate cap hedges 
were fully amortized and unrealized gains and losses recorded in accumulated other comprehensive income were also realized 
at that time. See Note 1 and Note 8 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual 
Report on Form 10-K for further information.

On December 16, 2021, we acquired MagSeal for a purchase price of $69.5 million, net of cash acquired, all payable in cash. 
Upon the closing of the transaction, we paid a gross total aggregate of $71.3 million in cash, a portion of which was by drawing 
down on the 2019 Revolving Credit Facility. This draw down on the 2019 Revolving Credit Facility was paid off by 
December 31, 2021. See Note 2 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report 
on Form 10-K for further information.

In October 2019, we acquired Nobles Parent Inc., the parent company of Nobles Worldwide, Inc. (“Nobles”) for an original 
purchase price of $77.0 million, net of cash acquired, all payable in cash. Upon the closing of the transaction, we paid a gross 
total aggregate of $77.3 million in cash by drawing down on the 2018 Revolving Credit Facility. 

On December 16, 2021, we entered into a sale-leaseback transaction for the building and related land for our Gardena 
performance center located in Carson, California (“Sale-Leaseback Agreement”). The building and related land was sold for 
$143.1 million and we recognized a gain of $132.5 million. As part of the Sale-Leaseback Agreement, we entered into an initial 
five year lease for the usage of the just sold building and related land. The future minimum base monthly lease payments during 
the initial five year period in aggregate total $19.6 million. See Note 5 to our consolidated financial statements included in Part 
IV, Item 15(a) of this Annual Report on Form 10-K for further information.

We expect to spend a total of $16.0 million to $18.0 million for capital expenditures in 2022 (excluding capital expenditures we 
will spend to restore the manufacturing capabilities related to our Guaymas performance center that was severely damaged by 
fire in June 2020), financed by cash generated from operations, principally to support new contract awards in Electronic 
Systems and Structural Systems. As part of our strategic plan to become a supplier of higher-level assemblies and win new 
contract awards, additional up-front investment in tooling will be required for newer programs which have higher engineering 
content and higher levels of complexity in assemblies. However, some portion of the expected capital expenditures in 2022 
could be delayed as a result of the COVID-19 pandemic.

We believe the ongoing aerospace and defense subcontractor consolidation makes acquisitions an increasingly important 
component of our future growth. We will continue to make prudent acquisitions and capital expenditures for manufacturing 
equipment and facilities to support long-term contracts for commercial and military aircraft and defense programs.

We continue to depend on operating cash flow and the availability of our Credit Facilities to provide short-term liquidity. Cash 
generated from operations and bank borrowing capacity is expected to provide sufficient liquidity to meet our obligations 
during the next twelve months from the date of issuance of these financial statements.

Cash Flow Summary

2021 Compared to 2020 

Net cash used in operating activities during 2021 was $0.6 million, compared to net cash provided by operating activities of 
$12.6 million during 2020. The lower cash provided by operating activities during 2021 was primarily due to higher contract 
assets, higher inventories, and higher accounts receivable, partially offset by higher net income and higher contract liabilities.

Net cash provided by investing activities during 2021 was $57.8 million compared to net cash used by investing activities of 
$5.5  million  during  2020.  The  higher  cash  provided  by  investing  activities  during  2021  was  primarily  due  to  proceeds  from 
sale-leaseback, partially offset by the payments for the acquisition of MagSeal.

Net cash used by financing activities during 2021 was $37.3 million compared to net cash provided by financing activities of 
$9.7  million  during  2020.  The  lower  cash  provided  by  financing  activities  during  2021  was  primarily  due  to  higher  net 
repayments of borrowings on the Credit Facilities.

2020 Compared to 2019 

See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2020 Annual 
Report on Form 10-K filed with the SEC on February 11, 2021, which is incorporated by reference herein.

Off-Balance Sheet Arrangements

Our off-balance sheet arrangements consist of operating and finance leases not recorded as a result of the practical expedients 
utilized, right of offset of industrial revenue bonds and associated failed sales-leasebacks on property and equipment, and 
indemnities, none of which we believe may have a material current or future effect on our financial condition, liquidity, capital 
resources, or results of operations.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Critical accounting policies and estimates are those accounting policies and estimates that can have a significant impact on the 
presentation of our financial condition and results of operations and that require the use of subjective estimates based upon past 
experience and management’s judgment. Because of the uncertainty inherent in such estimates, actual results may differ from 
these estimates. Below are those policies applied in preparing our financial statements that management believes are the most 
dependent on the application of estimates and assumptions. See Note 1 to our consolidated financial statements included in Part 
IV, Item 15(a) of this Annual Report on Form 10-K for additional accounting policies.

Revenue Recognition

Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use 
customer. This requires the building of tooling and manufacturing first article inspection products (prototypes) before volume 
manufacturing. Contracts with our customers generally include a termination for convenience clause.

We have a significant number of contracts that are started and completed within the same year, as well as contracts derived 
from long-term agreements and programs that can span several years. We recognize revenue under ASC 606, “Revenue from 
Contracts with Customers” (“ASC 606”), which utilizes a five-step model.

The definition of a contract for us is typically defined as a customer purchase order as this is when we achieve an enforceable 
right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase 
order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies of 
scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our 
customer. When that occurs, we would not recognize revenue until we have received the customer purchase order.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of 
account under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as 
revenue when, or as, control is transferred and the performance obligation is satisfied. The majority of our contracts have a 
single performance obligation as the promise to transfer the individual goods or services are highly interrelated or met the series 
guidance. For contracts with multiple performance obligations, we allocate the contract transaction price to each performance 
obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary 
method used to estimate the standalone selling price is the expected cost plus a margin approach, under which we forecast our 
expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We manufacture most products to customer specifications and the product cannot be easily modified for another customer. As 
such, these products are deemed to have no alternative use once the manufacturing process begins. In the event the customer 
invokes a termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable profit. Contract 

34

Table of Contents

costs typically include labor, materials, overhead, and when applicable, subcontractor costs. For most of our products, we are 
building assets with no alternative use and have enforceable right to payment, and thus, we recognize revenue using the over 
time method.

The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over 
time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-
cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of raw 
materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs incurred input 
method would be the most appropriate method. While the cost of raw materials could make up a significant amount of the total 
costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or services to the customer.

Contract estimates are based on various assumptions to project the outcome of future events that can span multiple months or 
years. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and 
availability of materials; and the performance of subcontractors.

As a significant change in one or more of these estimates could affect the progress completed (and related profitability) on our 
contracts, we review and update our contract-related estimates on a regular basis. We recognize such adjustments under the 
cumulative catch-up method. Under this method, the impact of the adjustment is recognized in the period the adjustment is 
identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate.

The impact of adjustments in contract estimates on our operating earnings can be reflected in either operating costs and 
expenses or revenue. See Note 1 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report 
on Form 10-K for the net impact of these adjustments to our consolidated financial statements for 2021.

Payments under long-term contracts may be received before or after revenue is recognized. When revenue is recognized before 
we bill our customer, a contract asset is created for the work performed but not yet billed. Similarly, when we receive payment 
before we ship our products to our customer and have met the shipping terms, a contract liability is created for the advance or 
progress payment. When a contract liability and a contract asset exist on the same contract, we report it on a net basis.

We record provisions for the total anticipated losses on contracts, considering total estimated costs to complete the contract 
compared to total anticipated revenues, in the period in which such losses are identified. The provisions for estimated losses on 
contracts require us to make certain estimates and assumptions, including those with respect to the future revenue under a 
contract and the future cost to complete the contract. Our estimate of the future cost to complete a contract may include 
assumptions as to changes in manufacturing efficiency, operating and material costs, and our ability to resolve claims and 
assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we may be 
required to adjust the provisions for estimated losses on contracts. The provision for estimated losses on contracts is included as 
part of contract liabilities on the consolidated balance sheets.

Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and 
other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded to 
cost of sales using the over time revenue recognition model. We review the value of the production cost of contracts on a 
quarterly basis to ensure when added to the estimated cost to complete, the value is not greater than the estimated realizable 
value of the related contracts.

Business Combinations

When a business is acquired, we allocate the purchase price by recording the assets acquired and liabilities assumed at their 
estimated fair values as of the acquisition date, with the excess cost recorded as goodwill. A preliminary fair value is 
determined once a business is acquired, with the final determination of fair value be completed no later than one year from the 
date of acquisition. 

To determine the estimated fair value of assets acquired and liabilities assumed requires significant judgment and estimates, 
including the selection of valuation methodologies, estimates of future revenues, costs and cash flows, discount rates, and 
selection of comparable companies. We engage the assistance of valuation specialists in concluding on fair value measurements 
in determining the fair value of assets acquired and liabilities assumed in business combinations. 

The fair value of the intangible assets is estimated using several valuation methodologies, including the income based or market 
based approaches, which represent Level 3 fair value measurements. Inputs to fair value analyses and other aspects of the 
allocation of the purchase price require judgment. The value for customer relationships is typically estimated based on a multi-
period excess earnings approach. The more significant inputs used in the customer relationships intangible asset valuation 
include (i) future revenue growth rates, (ii) projected gross margins, (iii) the customer attrition rate, and (iv) the discount rate. 
The useful lives are estimated based on the underlying agreements or the future economic benefit expected to be received from 
the assets. 

35

Table of Contents

Acquisition related costs are not included as components of consideration transferred but instead, expensed as incurred and are 
included in selling, general and administrative expenses in our consolidated statements of income. See Note 2 to our 
consolidated financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K.

Goodwill

Goodwill is evaluated for impairment on an annual basis on the first day of the fourth fiscal quarter. If certain factors occur, 
including significant under performance of our business relative to expected operating results, significant adverse economic and 
industry trends, significant decline in our market capitalization for an extended period of time relative to net book value, a 
decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we may 
be required to perform an interim impairment test prior to the fourth quarter. 

We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The 
qualitative approach for potential impairment analysis is performed to determine whether it is more likely than not that the fair 
value of a reporting unit was less than its carrying amount.

The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its 
carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach (which 
is based on a discounted cash flow model) and the market approach. Management’s cash flow projections include significant 
judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and discount 
rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, gross margins, 
and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair value of a reporting 
unit. The market approach also requires significant management judgment in selecting comparable business acquisitions and the 
transaction values observed and its related control premiums.

In the fourth quarter of 2021, the carrying amount of goodwill at the date of the most recent annual impairment evaluation for 
Electronic Systems and Structural Systems was $117.4 million and $53.4 million, respectively.

We acquired 100% of the equity interests of MagSeal on December 16, 2021, for a purchase price of $69.5 million, net of cash 
acquired. We recorded preliminary goodwill of $32.9 million in our Structural Systems segment, which is also our reporting 
unit. See Note 2 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K.

As of the date of our 2021 annual evaluation for goodwill impairment for the Structural Systems segment, which is also our 
reporting unit, we performed a step one goodwill impairment analysis as of the first day of the fourth quarter of 2021. The fair 
value of our Structural Systems segment exceeded its carrying value by 72% and thus, was not deemed impaired.

As of the date of our 2021 annual evaluation for goodwill impairment for the Electronic Systems segment, which is also our 
reporting unit, we performed a qualitative assessment as of the first day of the fourth quarter of 2021, which considered each of 
the following:  1) margin of passing most recent step one analysis, 2) earnings before interest, taxes, depreciation, and 
amortization, 3) long-term growth rate, 4) analyzing material adverse factors/changes between valuation dates, 5) general 
macroeconomic factors, and 6) industry and market conditions. Based upon our qualitative assessment, we concluded that it 
was more likely than not that the fair value of the reporting unit exceeded its carrying amount and thus, goodwill was not 
deemed impaired.

Other Intangible Assets

We amortize acquired other intangible assets with finite lives over the estimated economic lives of the assets, ranging from 2 
years to 19 years, generally using the straight-line method. The value of other intangibles acquired through business 
combinations has been estimated using present value techniques which involve estimates of future cash flows. We evaluate 
other intangible assets for recoverability considering undiscounted cash flows, when significant changes in conditions occur, 
and recognize impairment losses, if any, based upon the estimated fair value of the assets.

Accounting for Stock-Based Compensation

We measure and recognize compensation expense for share-based payment transactions to our employees and non-employees at 
their estimated fair value. The expense is measured at the grant date, based on the calculated fair value of the share-based 
award, and is recognized over the requisite service period (generally the vesting period of the equity award). The fair value of 
stock options are determined using the Black-Scholes-Merton (“Black-Scholes”) valuation model, which requires assumptions 
and judgments regarding stock price volatility, risk-free interest rates, and expected options terms. Management’s estimates 
could differ from actual results. The fair value of unvested stock awards is determined based on the closing price of the 
underlying common stock on the date of grant except for market condition awards for which the fair value was based on a 
Monte Carlo simulation model.

36

Table of Contents

Inventories

Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost basis 
for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to cost of 
sales as raw materials are placed into production and the related revenue is recognized. Inventoried costs include raw materials, 
outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle performance center expense, 
freight, handling costs, and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if 
necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best 
estimates given information currently available. The majority of our revenues are recognized over time, however, for revenue 
contracts where revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of 
control to the customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods.

Income Taxes

Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and 
liabilities. Deferred tax assets and liabilities are recognized, using enacted tax rates, for the expected future tax consequences of 
temporary differences between the book and tax bases of recorded assets and liabilities, operating losses, and tax credit 
carryforwards. Deferred tax assets are evaluated quarterly and are reduced by a valuation allowance if it is more likely than not 
that some portion or all of the deferred tax assets will not be realized.

Tax positions taken or expected to be taken in a tax return are recognized when it is more-likely-than-not, based on technical 
merits, to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of 
benefit that is greater than 50% likely of being realized upon ultimate settlement, including resolution of related appeals and/or 
litigation process, if any.

Recent Accounting Pronouncements

See Note 1 to our consolidated financial statements included in Part IV, Item 15(a) of this Annual Report on Form 10-K for a 
description of recent accounting pronouncements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our main market risk exposure relates to changes in U.S. and U.K. interest rates on our outstanding long-term debt. At 
December 31, 2021, we had borrowings of $287.7 million under our Credit Facilities.

The 2019 Term Loan bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as the London 
Interbank Offered Rate [“LIBOR”]) plus an applicable margin ranging from 1.50% to 2.50% per year or (ii) the Base Rate 
(defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate 
plus 1.00%) plus an applicable margin ranging from 0.50% to 1.50% per year, in each case based upon the consolidated total 
net adjusted leverage ratio.

The 2019 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as 
LIBOR) plus an applicable margin ranging from 1.50% to 2.50% per year or (ii) the Base Rate (defined as the highest of [a] 
Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable 
margin ranging from 0.50% to 1.50% per year, in each case based upon the consolidated total net adjusted leverage ratio.

The 2018 Term Loan bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as LIBOR) plus an 
applicable margin ranging from 3.75% to 4.00% per year or (ii) the Base Rate (defined as the highest of [a] Federal Funds Rate 
plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable margin ranging from 
3.75% to 4.00% per year, in each case based upon the consolidated total net adjusted leverage ratio.

A hypothetical 10% increase or decrease in the interest rate would have an immaterial impact on our financial condition and 
results of operations.

The interest rates on our Credit Facilities are based on LIBOR. See risks related to LIBOR under “Risk Factors” contained 
within Part I, Item 1A of this Annual Report on Form 10-K.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as 
amended (“Exchange Act”)) are designed to provide reasonable assurance that information required to be disclosed in reports 
we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in 
the rules and forms of the SEC and that such information is accumulated and communicated to our management, including the 
Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

Under the supervision and with the participation of our management, including the Chief Executive Officer and the Chief 
Financial Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and 
procedures as of the end of the period covered by this Annual Report on Form 10-K. Based on this evaluation, the Company’s 
Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the 
reasonable assurance level as of December 31, 2021.

Management’s Report on Internal Control Over Financial Reporting

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. The 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 (“GAAP”). The Company’s 
internal control over financial reporting 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 assets of the Company; (ii) 
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with 
authorizations of management and directors of the Company; 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 our 
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.

Management of the Company has assessed the effectiveness of the Company’s internal control over financial reporting as of 
December 31, 2021. In making this assessment, management used the criteria set forth by the Committee of Sponsoring 
Organizations of the Treadway Commission (“COSO”) Internal Control-Integrated Framework (2013). Based on our 
assessment and those criteria, management concluded that the Company maintained effective internal control over financial 
reporting as of December 31, 2021.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2021 has been audited by 
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included in 
Item 15 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the 
Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial 
reporting during the quarter ended December 31, 2021.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Ducommun Incorporated

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Ducommun Incorporated and its subsidiaries (the 
“Company”) as of December 31, 2021 and 2020, and the related consolidated statements of income, of comprehensive income, 
of changes in shareholders’ equity and of cash flows for each of the three years in the period ended December 31, 2021, 
including the related notes and financial statement schedule listed in the index appearing under Item 15(a)2 (collectively 
referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial 
reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the United 
States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over 
financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the COSO.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for 
leases in 2019.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included 
in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to 
express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial 
reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight 
Board (United States) (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 
audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material 
respects. 

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement 
of the consolidated 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 consolidated 
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 consolidated financial statements. Our audit of internal 
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the 
risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based 
on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (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 company are being made only in accordance with authorizations of management and directors of the 
company; 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.

42

Table of Contents

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.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or 
disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or 
complex judgments. The communication of 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 matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Acquisition of Magnetic Seal LLC - Valuation of the Customer Relationships Intangible Asset

As described in Notes 1 and 2 to the consolidated financial statements, the Company completed the acquisition of Magnetic 
Seal LLC for net consideration of $69.5 million on December 16, 2021. The intangible assets acquired of $30.1 million, 
including $24.8 million for customer relationships, were determined based on the estimated fair values using valuation 
techniques consistent with the income approach to measure fair value. The value for customer relationships was estimated 
based on a multi-period excess earnings approach. Inputs to the income approach model and other aspects of the allocation of 
the purchase price require judgment. The more significant inputs used in the customer relationships intangible asset valuation 
include (i) future revenue growth rates, (ii) projected gross margins, (iii) the customer attrition rate, and (iv) the discount rate. 

The principal considerations for our determination that performing procedures relating to the valuation of the customer 
relationships intangible asset acquired in the acquisition of Magnetic Seal LLC is a critical audit matter are (i) the significant 
judgment by management when determining the fair value of the acquired intangible asset; (ii) the high degree of auditor 
judgment, subjectivity and effort in performing procedures and evaluating management’s significant assumptions related to 
future revenue growth rates, projected gross margins, the customer attrition rate, and the discount rate; and (iii) the audit effort 
involved the use of professionals with specialized skill and knowledge.  

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to 
acquisition accounting, including controls over management’s valuation of the customer relationships intangible asset. These 
procedures also included, among others (i) reading the purchase agreement; (ii) testing management’s process for determining 
the fair value of the customer relationships intangible asset; (iii) evaluating the appropriateness of the multi-period excess 
earnings approach; (iv) testing the completeness and accuracy of the underlying data used in the multi-period excess earnings 
approach; and (v) evaluating the reasonableness of the significant assumptions used by management related to future revenue 
growth rates, projected gross margins, the customer attrition rate, and the discount rate for the customer relationships intangible 
asset. Evaluating the reasonableness of the future revenue growth rates and projected gross margins involved considering the 
past performance of the acquired business and consistency with industry and economic forecasts. Professionals with specialized 
skill and knowledge were used to assist in the evaluation of (i) the appropriateness of the Company’s multi-period excess 
earnings approach and (ii) the reasonableness of the customer attrition rate and discount rate significant assumptions.

DUCOMMUN INCORPORATED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

Description of Business

We are a leading global provider of innovative, value-added proprietary products and manufacturing solutions for high-
performance products and high-cost-of failure applications used primarily in the aerospace and defense (“A&D”), industrial, 
medical, and other industries (collectively, “Industrial”). Our operations are organized into two primary businesses:  Electronic 
Systems segment (“Electronic Systems”) and Structural Systems segment (“Structural Systems”), each of which is a reportable 
operating segment. Electronic Systems designs, engineers and manufactures high-reliability electronic and electromechanical 
products used in worldwide technology-driven markets including A&D and Industrial end-use markets. Electronic Systems’ 
product offerings primarily range from prototype development to complex assemblies. Structural Systems designs, engineers 
and manufactures large, complex contoured aerostructure components and assemblies and supplies composite and metal bonded 
structures and assemblies. Structural Systems’ products are primarily used on commercial aircraft, military fixed-wing aircraft, 
and military and commercial rotary-wing aircraft. All reportable operating segments follow the same accounting principles. 

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the 
United States of America (“GAAP”), and include the accounts of Ducommun Incorporated and its subsidiaries (“Ducommun,” 
the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions.

Our fiscal quarters typically end on the Saturday closest to the end of March, June and September for the first three fiscal 
quarters of each year, and on December 31 for our fourth fiscal quarter. As a result of using fiscal quarters for the first three 
quarters combined with leap years, our first and fourth fiscal quarters can range between 12 1/2 weeks to 13 1/2 weeks while 
the second and third fiscal quarters remain at a constant 13 weeks per fiscal quarter.

Changes in Accounting Policies

We adopted Accounting Standards Codification (“ASC”) 842, “Leases” (“ASC 842”), on January 1, 2019.

We applied ASC 842 using the additional transition method and therefore, recognized the cumulative effect of initially applying 
ASC 842 as an adjustment to the opening consolidated balance sheet at January 1, 2019. Therefore, the comparative 
information has not been adjusted and continues to be reported under the previous lease accounting standard, ASC 840, 
“Leases” (“ASC 840”).

Use of Estimates

Certain amounts and disclosures included in the consolidated financial statements required management to make estimates and 
judgments that affect the amount of assets, liabilities (including forward loss reserves), revenues and expenses, and related 
disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other 
assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results 
could differ from these estimates.

Reclassifications

Certain prior period amounts have been reclassified to conform to current year’s presentation.

Fair Value

Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair 
value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine the fair value. 
Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. Level 2 
refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values estimated using 
significant unobservable inputs.

We have money market funds and they are included as cash and cash equivalents. We also have forward interest rate swap 
agreements and had interest rate cap hedge agreements and the fair value of the forward interest rate swap agreements and 
interest rate cap hedge agreements were determined using pricing models that use observable market inputs as of the balance 
sheet date, a Level 2 measurement. The interest rate cap hedges matured during the second quarter of 2020 and as such, the 
premium was zero as of December 31, 2021.

There were no transfers between Level 1, Level 2, or Level 3 financial instruments in either 2021 or 2020.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets 
are valued at cost, which approximates fair value, which we classify as Level 1. See Fair Value above.

Derivative Instruments

We recognize derivative instruments on our consolidated balance sheets at their fair value. On the date that we enter into a 
derivative contract, we designate the derivative instrument as a fair value hedge, a cash flow hedge, or a derivative instrument 
that will not be accounted for using hedge accounting methods. On November 29, 2021, we entered into forward interest rate 
swap agreements, all with an effective date of January 1, 2024 (“Forward Interest Rate Swaps”) to manage our exposure to 
interest rate movements on a portion of our debt. As such, we have made the following cash flow hedging relationship elections 
to qualify for hedge accounting treatment related to the Forward Interest Rate Swaps as our current term loans mature before 
the expiration of the Forward Interest Rate Swaps: 1) Probability of forecasted transactions, and 2) Assessment of effectiveness. 
See Note 8. As of December 31, 2021, all of our derivative instruments were designated as cash flow hedges.

We record changes in the fair value of a derivative instrument that is highly effective and that is designated and qualifies as a 
cash flow hedge in other comprehensive income (loss), net of tax until our earnings are affected by the variability of cash flows 
of the underlying hedged item. We report changes in the fair values of derivative instruments that are not designated or do not 
qualify for hedge accounting in current period earnings. We classify cash flows from derivative instruments in the consolidated 
statements of cash flows in the same category as the item being hedged or on a basis consistent with the nature of the 
instrument. Since the Forward Interest Rate Swaps are not effective until January 1, 2024, in both 2021 and 2020, we only 
recorded the changes in the fair value of the derivative instruments that were highly effective and that were designated and 
qualified as cash flow hedges in other long term liabilities and other comprehensive income (loss) of $1.7 million and zero, 
respectively.

When we determine that a derivative instrument is not highly effective as a hedge, we discontinue hedge accounting 
prospectively. In all situations in which we discontinue hedge accounting and the derivative instrument remains outstanding, we 
will carry the derivative instrument at its fair value on our consolidated balance sheets and recognize subsequent changes in its 
fair value in our current period earnings.

Allowance for Credit Losses

We maintain an allowance for credit losses for expected losses from the inability of customers to make required payments. The 
allowance for credit losses is evaluated periodically for expected credit losses based on the financial condition of customers and 
their payment history, the aging of accounts receivable, historical write-off experience and other assumptions, such as current 
assessment of economic conditions.

Inventories

Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost basis 
for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to cost of 
sales as raw materials are placed into production and the related revenue is recognized. Inventoried costs include raw materials, 
outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle performance center expense, 
freight, handling costs, and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if 
necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best 
estimates given information currently available. The majority of our revenues are recognized over time, however, for revenue 

50

Table of Contents

contracts where revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of 
control to the customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods.

Property and Equipment and Depreciation

Property and equipment, including assets recorded under operating and finance leases, are recorded at cost. Depreciation and 
amortization are computed using the straight-line method over the estimated useful lives of the related assets, or the lease term 
if shorter for leasehold improvements. Repairs and maintenance are charged to expense as incurred. We evaluate long-lived 
assets for recoverability considering undiscounted cash flows, when significant changes in conditions occur, and recognize 
impairment losses if any, based upon the fair value of the assets.

Business Combinations

When a business is acquired, we allocate the purchase price by recording the assets acquired and liabilities assumed at their 
estimated fair values as of the acquisition date, with the excess cost recorded as goodwill. A preliminary fair value is 
determined once a business is acquired, with the final determination of fair value be completed no later than one year from the 
date of acquisition. 

To determine the estimated fair value of assets acquired and liabilities assumed requires significant judgment and estimates, 
including the selection of valuation methodologies, estimates of future revenues, costs and cash flows, discount rates, and 
selection of comparable companies. We engage the assistance of valuation specialists in concluding on fair value measurements 
in determining the fair value of assets acquired and liabilities assumed in business combinations. 

The fair value of the intangible assets is estimated using several valuation methodologies, including the income based or market 
based approaches, which represent Level 3 fair value measurements. Inputs to fair value analyses and other aspects of the 
allocation of the purchase price require judgment. The value for customer relationships is typically estimated based on a multi-
period excess earnings approach. The more significant inputs used in the customer relationships intangible asset valuation 
include (i) future revenue growth rates, (ii) projected gross margins, (iii) the customer attrition rate, and (iv) the discount rate. 
The useful lives are estimated based on the underlying agreements or the future economic benefit expected to be received from 
the assets. 

Acquisition related costs are not included as components of consideration transferred but instead, expensed as incurred and are 
included in selling, general and administrative expenses in our consolidated statements of income. See Note 2.

Goodwill

Goodwill is evaluated for impairment on an annual basis on the first day of the fourth fiscal quarter. If certain factors occur, 
including significant under performance of our business relative to expected operating results, significant adverse economic and 
industry trends, significant decline in our market capitalization for an extended period of time relative to net book value, a 
decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we may 
be required to perform an interim impairment test prior to the fourth quarter. 

We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The 
qualitative approach for potential impairment analysis is performed to determine whether it is more likely than not that the fair 
value of a reporting unit was less than its carrying amount.

The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its 
carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach (which 
is based on a discounted cash flow model) and the market approach. Management’s cash flow projections include significant 
judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and discount 
rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, gross margins, 
and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair value of a reporting 
unit. The market approach also requires significant management judgment in selecting comparable business acquisitions and the 
transaction values observed and its related control premiums.

In the fourth quarter of 2021, the carrying amount of goodwill at the date of the most recent annual impairment evaluation for 
Electronic Systems and Structural Systems was $117.4 million and $53.4 million, respectively.

We acquired 100% of the equity interests of Magnetic Seal LLC (f/k/a Magnetic Seal Corporation, “MagSeal”) on December 
16, 2021, for a purchase price of $69.5 million, net of cash acquired. We recorded preliminary goodwill of $32.9 million in our 
Structural Systems segment, which is also our reporting unit. See Note 2.

51

Table of Contents

As of the date of our 2021 annual evaluation for goodwill impairment for the Structural Systems segment, which is also our 
reporting unit, we performed a step one goodwill impairment analysis as of the first day of the fourth quarter of 2021. The fair 
value of our Structural Systems segment exceeded its carrying value by 72% and thus, was not deemed impaired.

As of the date of our 2021 annual evaluation for goodwill impairment for the Electronic Systems segment, which is also our 
reporting unit, we performed a qualitative assessment as of the first day of the fourth quarter of 2021, which considered each of 
the following:  1) margin of passing most recent step one analysis, 2) earnings before interest, taxes, depreciation, and 
amortization, 3) long-term growth rate, 4) analyzing material adverse factors/changes between valuation dates, 5) general 
macroeconomic factors, and 6) industry and market conditions. Based upon our qualitative assessment, we concluded that it 
was more likely than not that the fair value of the reporting unit exceeded its carrying amount and thus, goodwill was not 
deemed impaired.

Other Intangible Assets

We amortize acquired other intangible assets with finite lives over the estimated economic lives of the assets, ranging from 2 to 
19 years, generally using the straight-line method. The value of other intangibles acquired through business combinations has 
been estimated using present value techniques which involve estimates of future cash flows. We evaluate other intangible assets 
for recoverability considering undiscounted cash flows when significant changes in conditions occur, and recognize impairment 
losses, if any, based upon the estimated fair value of the assets.

Restructuring Charges

In May 2020, management approved and commenced a restructuring plan in the Structural Systems segment mainly to reduce 
headcount in response to the impact from the COVID-19 pandemic on commercial aerospace demand outlook. We recorded an 
aggregate total of $2.4 million for severance and benefit costs which were charged to restructuring charges during the year 
ended December 31, 2020.

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss, as reflected on the consolidated balance sheets under the equity section, was comprised 
of cumulative pension and retirement liability adjustments, net of tax, and change in net unrealized gains and losses on cash 
flow hedges, net of tax.

Revenue Recognition

Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use 
customer. This requires the building of tooling and manufacturing first article inspection products (prototypes) before volume 
manufacturing. Contracts with our customers generally include a termination for convenience clause.

We have a significant number of contracts that are started and completed within the same year, as well as contracts derived 
from long-term agreements and programs that can span several years. We recognize revenue under ASC 606, “Revenue from 
Contracts with Customers” (“ASC 606”), which utilizes a five-step model.

The definition of a contract for us is typically defined as a customer purchase order as this is when we achieve an enforceable 
right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase 
order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies of 
scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our 
customer. When that occurs, we would not recognize revenue until we have received the customer purchase order.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of 
account under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as 
revenue when, or as, control is transferred and the performance obligation is satisfied. The majority of our contracts have a 
single performance obligation as the promise to transfer the individual goods or services are highly interrelated or met the series 
guidance. For contracts with multiple performance obligations, we allocate the contract transaction price to each performance 
obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary 
method used to estimate the standalone selling price is the expected cost plus a margin approach, under which we forecast our 
expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We manufacture most products to customer specifications and the product cannot be easily modified for another customer. As 
such, these products are deemed to have no alternative use once the manufacturing process begins. In the event the customer 
invokes a termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable profit. Contract 
costs typically include labor, materials, overhead, and when applicable, subcontractor costs. For most of our products, we are 
building assets with no alternative use and have enforceable right to payment, and thus, we recognize revenue using the over 
time method.

52

Table of Contents

The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over 
time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-
cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of raw 
materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs incurred input 
method would be the most appropriate method. While the cost of raw materials could make up a significant amount of the total 
costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or services to the customer.

Contract estimates are based on various assumptions to project the outcome of future events that can span multiple months or 
years. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and 
availability of materials; and the performance of subcontractors.

As a significant change in one or more of these estimates could affect the progress completed (and related profitability) on our 
contracts, we review and update our contract-related estimates on a regular basis. We recognize such adjustments under the 
cumulative catch-up method. Under this method, the impact of the adjustment is recognized in the period the adjustment is 
identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. 

The impact of adjustments in contract estimates on our operating earnings can be reflected in either operating costs and 
expenses or revenue. 

Net cumulative catch-up adjustments on profit recorded were not material for both years ended December 31, 2021 and 
December 31, 2020.

Payments under long-term contracts may be received before or after revenue is recognized. When revenue is recognized before 
we bill our customer, a contract asset is created for the work performed but not yet billed. Similarly, when we receive payment 
before we ship our products to our customer and have met the shipping terms, a contract liability is created for the advance or 
progress payment. When a contract liability and a contract asset exist on the same contract, we report it on a net basis.

We record provisions for the total anticipated losses on contracts, considering total estimated costs to complete the contract 
compared to total anticipated revenues, in the period in which such losses are identified. The provisions for estimated losses on 
contracts require us to make certain estimates and assumptions, including those with respect to the future revenue under a 
contract and the future cost to complete the contract. Our estimate of the future cost to complete a contract may include 
assumptions as to changes in manufacturing efficiency, operating and material costs, and our ability to resolve claims and 
assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we may be 
required to adjust the provisions for estimated losses on contracts. The provision for estimated losses on contracts is included as 
part of contract liabilities on the consolidated balance sheets. As of December 31, 2021 and 2020, provision for estimated losses 
on contracts were $2.8 million and $2.3 million, respectively.

Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and 
other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded to 
cost of sales using the over time revenue recognition model. We review the value of the production cost of contracts on a 
quarterly basis to ensure when added to the estimated cost to complete, the value is not greater than the estimated realizable 
value of the related contracts. As of December 31, 2021 and 2020, production costs of contracts were $8.0 million and $7.0 
million, respectively.

Contract Assets and Contract Liabilities

Contract assets consist of our right to payment for work performed but not yet billed. Contract assets are transferred to accounts 
receivable when we bill our customers. We bill our customers when we ship the products and meet the shipping terms within 
the revenue contract. Contract liabilities consist of advance or progress payments received from our customers prior to the time 
transfer of control occurs plus the estimated losses on contracts. When a contract liability and a contract asset exist on the same 
contract, we report it on a net basis.

Contract assets and contract liabilities from revenue contracts with customers are as follows:

The increase in our contract assets as of December 31, 2021 compared to December 31, 2020 was primarily due to a net 
increase of products in work in process.

The increase in our contract liabilities as of December 31, 2021 compared to December 31, 2020 was primarily due to a net 
increase of advance or progress payments received from our customers in the current year. We recognized $20.9 million of the 
contract liabilities as of December 31, 2020 as revenues during the year ended December 31, 2021.

Performance obligations are defined as customer placed purchase orders (“POs”) with firm fixed price and firm delivery dates. 
Our remaining performance obligations as of December 31, 2021 totaled $814.1 million. We anticipate recognizing an 
estimated 70% of our remaining performance obligations as revenue during the next 12 months with the remaining performance 
obligations being recognized in 2023 and beyond.

Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and 
liabilities. Deferred tax assets and liabilities are recognized, using enacted tax rates, for the expected future tax consequences of 
temporary differences between the book and tax bases of recorded assets and liabilities, operating losses, and tax credit 
carryforwards. Deferred tax assets are evaluated quarterly and are reduced by a valuation allowance if it is more likely than not 
that some portion or all of the deferred tax assets will not be realized.

Tax positions taken or expected to be taken in a tax return are recognized when it is more-likely-than-not, based on technical 
merits, to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of 
benefit that is greater than 50% likely of being realized upon ultimate settlement, including resolution of related appeals and/or 
litigation process, if any.

Litigation and Commitments

In the normal course of business, we are defendants in certain litigation, claims and inquiries, including matters relating to 
environmental laws. In addition, we make various commitments and incur contingent liabilities. Management’s estimates 
regarding contingent liabilities could differ from actual results.

Environmental Liabilities

Environmental liabilities are recorded when environmental assessments and/or remedial efforts are probable and costs can be 
reasonably estimated. Generally, the timing of these accruals coincides with the completion of a feasibility study or our 
commitment to a formal plan of action. Further, we review and update our environmental accruals as circumstances change and/
or additional information is obtained that reasonably could be expected to have a meaningful effect on the outcome of a matter 
or the estimated cost thereof.

Accounting for Stock-Based Compensation

We measure and recognize compensation expense for share-based payment transactions to our employees and non-employees at 
their estimated fair value. The expense is measured at the grant date, based on the calculated fair value of the share-based 
award, and is recognized over the requisite service period (generally the vesting period of the equity award). The fair value of 
stock options are determined using the Black-Scholes-Merton (“Black-Scholes”) valuation model, which requires assumptions 
and judgments regarding stock price volatility, risk-free interest rates, and expected options terms. Management’s estimates 
could differ from actual results. The fair value of unvested stock awards is determined based on the closing price of the 
underlying common stock on the date of grant except for market condition awards for which the fair value was based on a 
Monte Carlo simulation model. 

Government Grant

On November 15, 2021, we were awarded an Aviation Manufacturing Jobs Protection Program grant from the U.S. Department 
of Transportation of $4.0 million. As part of the award, we have to meet certain requirements over a six month performance 
period from November 15, 2021 to May 14, 2022. As of December 31, 2021, we have received $2.0 million with the remaining 
$2.0 million included as other current assets and expected to be received during 2022. We recorded $0.9 million and 
$0.1 million as a reduction of cost of sales and selling, general and administrative expenses, respectively, in 2021 with the 
remaining $3.0 million included as accrued and other liabilities.

Charitable Contributions

We contributed $0.3 million to the Ducommun Foundation during 2021.

Earnings Per Share

Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average number 
of common shares outstanding in each period. Diluted earnings per share is computed by dividing income available to common 
shareholders by the weighted-average number of common shares outstanding, plus potentially dilutive shares that could be 
issued if exercised or converted into common stock in each period.

The net income and weighted-average common shares outstanding used to compute earnings per share were as follows:

Net income
Weighted-average number of common shares outstanding
Basic weighted-average common shares outstanding
Dilutive potential common shares
Diluted weighted-average common shares outstanding

In November 2021, the FASB issued ASU 2021-10, “Government Assistance (Topic 832) - Disclosures by Business Entities 
about Government Assistance” (“ASU 2021-10”), which increases the transparency of government assistance including (1) the 
types of assistance, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on an entity’s financial

statements. The new guidance is effective for fiscal years beginning after December 15, 2021, which will be our interim period 
beginning January 1, 2022. Early adoption is permitted and thus, we have chosen to early adopt ASU 2021-10 beginning in 
2021 and the adoption of this standard did not have a material impact on our consolidated financial statements.

In October 2020, the FASB issued ASU 2020-10, “Codification Improvements” (“ASU 2020-10”), which affect a wide variety 
of Topics in the Accounting Standards Codification (“Codification”). ASU 2020-10, among other things, contains amendments 
that improve the consistency of the Codification by including all disclosure guidance in the appropriate Disclosure Section 
(Section 50). Many of the amendments arose as the FASB provided an option to give certain information either on the face of 
the financial statements or in the notes to financial statements and that option only was included in the Other Presentation 
Matters Section (Section 45) of the Codification. Those amendments are not expected to change current practice. The new 
guidance is effective for fiscal years beginning after December 15, 2020, which was our interim period beginning January 1, 
2021. The adoption of this standard did not have a material impact on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740), Simplifying the Accounting for Income 
Taxes” (“ASU 2019-12”), which removes certain exceptions and provides guidance on various areas of tax accounting. The 
new guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal 
years, which was our interim period beginning January 1, 2021. The adoption of this standard did not have a material impact on 
our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General 
(Topic 715-20):  Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans” (“ASU 
2018-14”), which will remove disclosures that no longer are considered cost-beneficial, clarify the specific requirements of 
disclosures, and add disclosure requirements identified as relevant. The new guidance is effective for fiscal years beginning 
after December 15, 2020, including interim periods within those fiscal years, which was our interim period beginning January 
1, 2021. The adoption of this standard did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Standards

In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805) - Accounting for Contract Assets and 
Contract Liabilities from Contracts with Customers” (“ASU 2021-08”), which improves the accounting for acquired revenue 
contracts with customers in a business combination. The new guidance is effective for fiscal years beginning after December 
15, 2022, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2023. Early 
adoption is permitted. We are evaluating the impact of this standard.

In August 2020, the FASB issued ASU 2020-06, “Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives 
and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) - Accounting for Convertible Instruments and Contracts in 
an Entity’s Own Equity” (“ASU 2020-06”), which simplifies reporting or provides clarification on various topics, including 
clarification that an entity should use the weighted-average share count from each quarter when calculating the year-to-date 
weighted-average share count. The new guidance is effective for fiscal years beginning after December 15, 2021, including 
interim periods within those fiscal years, which will be our interim period beginning January 1, 2022. Early adoption is 
permitted. We are evaluating the impact of this standard.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference 
Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional guidance for a limited time for contracts that 
reference London Interbank Offered Rate (“LIBOR”), to ease the potential burden in accounting for, or recognizing the effects, 
of reference rate reform on financial reporting as a result of the cessation of LIBOR. The new guidance is effective at any time 
after March 12, 2020 but no later than December 31, 2022. We have made the following elections related to our current cash 
flow hedging relationships as our current term loans mature before the expiration of the Forward Interest Rate Swaps: 1) 
Probability of forecasted transactions, and 2) Assessment of effectiveness. See Note 8.

Note 2. Business Combinations

On December 16, 2021, we acquired 100.0% of the outstanding equity interests of Magnetic Seal LLC (f/k/a Magnetic Seal 
Corporation, “MagSeal”), a privately-held leading provider of high-impact, military-proven magnetic seals for critical systems 
in aerospace and defense applications, offering sealing solutions that are engineered to perform in high-speed, high-vibration, 
and other challenging environments. MagSeal is located in Warren, Rhode Island. The acquisition of MagSeal will continue to 
advance our strategy to diversify and offer more customized, value-driven engineered products with aftermarket opportunities.

The purchase price for MagSeal was $69.5 million, net of cash acquired, all payable in cash. We paid a gross aggregate of 
$71.3 million in cash upon the closing of the transaction. We allocated the preliminary gross purchase price of $71.3 million to 
the assets acquired and liabilities assumed at their estimated fair values. The excess of the purchase price over the aggregate fair 
values of the net assets was recorded as goodwill.

The intangible assets acquired of $30.1 million were determined based on the estimated fair values using valuation techniques 
consistent with the income approach to measure fair value, which represented Level 3 fair value measurements. The useful lives 
were estimated based on the underlying agreements or the future economic benefit expected to be received from the assets. The 
value for customer relationships and backlog were estimated based on a multi-period excess earnings approach, while the value 
for trade name was assessed using the relief from royalty methodology. Inputs to the income approach models and other aspects 
of the allocation of the purchase price require judgment. The more significant inputs used in the customer relationships 
intangible asset valuation include (i) future revenue growth rates, (ii) projected gross margins, (iii) the customer attrition rate, 
and (iv) the discount rate.

The goodwill of $32.9 million arising from the acquisition is attributable to the benefits we expect to derive from expected 
synergies from the transaction, including complementary products that will enhance our overall product portfolio, opportunities 
within new markets, and an acquired assembled workforce. All the goodwill was assigned to the Structural Systems segment. 
The MagSeal acquisition, for tax purposes, is deemed an asset acquisition and thus, is deductible for income tax purposes.

Acquisition related transaction costs were not included as components of consideration transferred but have been expensed as 
incurred. Total acquisition-related transaction costs incurred by us were $0.9 million during 2021 and charged to selling, 
general and administrative expenses. 

MagSeal’s results of operations have been included in our consolidated statements of income since the date of acquisition as 
part of the Structural Systems segment and were immaterial since the date of acquisition. Pro forma results of operations of the 
MagSeal acquisition have not been presented as the effect of the MagSeal acquisition was not material to our financial results 
for both 2021 and 2020.

Note 5. Leases

Sale-Leaseback Transaction

On December 16, 2021, we entered into a sale-leaseback transaction for the building and related land for our Gardena 
performance center located in Carson, California (“Sale-Leaseback Agreement”). The building and related land was sold for 
$143.1 million and we have no continuing involvement. The carrying value of the building and related land was $9.4 million 
and we recognized a gain of $132.5 million. As part of the Sale-Leaseback Agreement, we entered into an initial five year lease 
for the usage of the just sold building and related land, with three options to renew in five year increments. The lease was 
classified as an operating lease and the future minimum base monthly lease payments during the initial five year period in 
aggregate total $19.6 million.

All Leases

We elected to utilize the following practical expedients that are permitted under ASC 842:

•

•

As an accounting policy election by class of underlying asset, elected not to separate nonlease components from lease 
components and instead to account for each separate lease component and the nonlease components associated with 
that lease component as a single lease component; and

As an accounting policy election not to apply the recognition requirements in ASC 842 to short term leases (a lease at 
commencement date has a lease term of 12 months or less and does not contain a purchase option that the lessee is 
reasonably certain to exercise).

We have operating and finance leases for manufacturing facilities, corporate offices, and various equipment. Our leases have 
remaining lease terms of 1 to 10 years, some of which include options to extend the leases for up to 15 years, and some of 
which include options to terminate the leases within 1 year.

When a lease is identified, we recognize a right-of-use asset and a corresponding lease liability based on the present value of the 
lease payments over the lease term discounted using our incremental borrowing rate, unless an implicit rate is readily 
determinable. As the discount rate in our leases is usually not readily available, we use our own incremental borrowing rate as 
the discount rate. Our incremental borrowing rate is based on the interest rate on our term loan, which is a secured rate. The 
interest rate on our term loan is based on London Interbank Offered Rate (“LIBOR”) plus an applicable margin.

The weighted average discount rates were as follows:

not yet commenced. These operating leases will commence during 2022 with lease terms of 7 years.

Finance lease payments related to options to extend lease terms that are reasonably certain of being exercised are not 
significant. As of December 31, 2021, there are no legally binding minimum lease payments for leases signed but not yet

We perform our annual goodwill impairment test as of the first day of the fourth quarter. If certain factors occur, including 
significant under performance of our business relative to expected operating results, significant adverse economic and industry 
trends, significant decline in our market capitalization for an extended period of time relative to net book value, a decision to 
divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we may be required 
to perform an interim impairment test prior to the fourth quarter. 

We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The 
qualitative approach for potential impairment analysis to determine whether it is more likely than not that the fair value of a 
reporting unit was less than its carrying amount.

The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its 
carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach (which 
is based on a discounted cash flow model) and market approach. Management’s cash flow projections include significant 
judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and discount 
rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, gross margins, 
and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair value of a reporting 
unit. The market approach also requires significant management judgment in selecting comparable business acquisitions and the 
transaction values observed and its related control premiums.

Our most recent step one goodwill impairment test for our Electronic Systems reporting unit was as of the first day of the fourth 
quarter of 2019 where the fair value of our Electronic Systems reporting unit exceeded its carrying value by 44%. No material 
adverse factors/changes have occurred since the fourth quarter of 2019 and thus, for our annual goodwill impairment test of our

Electronic Systems reporting unit as of the first day of the fourth quarter of 2021, we used a qualitative assessment and 
determined it was not more likely than not that the fair value of a reporting unit was less than its carrying amount. As our 
commercial aerospace end-use market business continues to be negatively impacted by the COVID-19 pandemic, we performed 
a step one goodwill impairment test for our Structural Systems reporting unit as of the first day of the fourth quarter of 2021, 
where the fair value of our Structural Systems reporting unit exceeded its carrying value by 72%. Thus, the respective goodwill 
amounts were not deemed impaired.

On December 16, 2021, we acquired 100% of the outstanding equity of Magnetic Seal LLC (f/k/a Magnetic Seal Corporation, 
“MagSeal”) for a purchase price of $69.5 million, net of cash acquired. We preliminarily allocated the gross purchase price of 
$71.3 million to the assets acquired and the liabilities assumed at their estimated fair values. The excess of the purchase price 
over the aggregate fair values was recorded as goodwill within the Structural Systems reporting unit. See Note 2.

Other intangible assets are related to acquisitions, including MagSeal, and recorded at fair value at the time of the acquisition. 
Other intangible assets with finite lives are generally amortized on the straight-line method over periods ranging from 2 to 19 
years. Intangible assets are as follows:

In December 2019, we completed the refinancing of a portion of our existing debt by entering into a new revolving credit 
facility (“2019 Revolving Credit Facility”) to replace the then existing revolving credit facility that was entered into in 
November 2018 (“2018 Revolving Credit Facility”) and entered into a new term loan (“2019 Term Loan”). The 2019 
Revolving Credit Facility is a $100.0 million senior secured revolving credit facility that matures on December 20, 2024 
replacing the $100.0 million 2018 Revolving Credit Facility that would have matured on November 21, 2023. The 2019 Term 
Loan is a $140.0 million senior secured term loan that matures on December 20, 2024. We also have an existing $240.0 million 
senior secured term loan that was entered into in November 2018 that matures on November 21, 2025 (“2018 Term Loan”). The 
original amounts available under the 2019 Revolving Credit Facility, 2019 Term Loan, and 2018 Term Loan (collectively, the 
“Credit Facilities”) in aggregate, totaled $480.0 million. 

The 2019 Term Loan bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as the London 
Interbank Offered Rate [“LIBOR”]) plus an applicable margin ranging from 1.50% to 2.50% per year or (ii) the Base Rate 
(defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate 
plus 1.00%) plus an applicable margin ranging from 0.50% to 1.50% per year, in each case based upon the consolidated total 
net adjusted leverage ratio, typically payable monthly or quarterly. In addition, the 2019 Term Loan requires installment 
payments of 1.25% of the original outstanding principal balance of the 2019 Term Loan amount on a quarterly basis, on the last 
day of the calendar quarter. During 2021, we made the required quarterly payments, in aggregate totaling $7.0 million.

The 2019 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as 
LIBOR) plus an applicable margin ranging from 1.50% to 2.50% per year or (ii) the Base Rate (defined as the highest of [a] 
Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable 
margin ranging from 0.50% to 1.50% per year, in each case based upon the consolidated total net adjusted leverage ratio, 
typically payable quarterly. The undrawn portion of the commitment of the 2019 Revolving Credit Facility is subject to a 
commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio. However, the 
2019 Revolving Credit Facility does not require any principal installment payments.

The 2018 Term Loan bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as LIBOR plus an 
applicable margin ranging from 3.75% to 4.00% per year or (ii) the Base Rate (defined as the highest of [a] Federal Funds Rate 
plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable margin ranging from 
3.75% to 4.00% per year, in each case based upon the consolidated total net adjusted leverage ratio, typically payable monthly 
or quarterly. In addition, the 2018 Term Loan required installment payments of 0.25% of the outstanding principal balance of 
the 2018 Term Loan amount on a quarterly basis. 

Further, under the Credit Facilities, if we exceed the annual excess cash flow threshold, we are required to make an annual 
additional principal payment based on the consolidated adjusted leverage ratio. The annual mandatory excess cash flow 
payment is based on (i) 50% of the excess cash flow amount if the adjusted leverage ratio is greater than 3.25 to 1.0, (ii) 25% of 
the excess cash flow amount if the adjusted leverage ratio is less than or equal to 3.25 to 1.0 but greater than 2.50 to 1.0, and 
(iii) zero percent of the excess cash flow amount if the consolidated adjusted leverage ratio is less than or equal to 2.50 to 1.0. 
During the first quarter of 2021, we made the required 2020 annual excess cash flow payment of $0.9 million. As of 
December 31, 2021, we were in compliance with all covenants required under the Credit Facilities. 

We drew down $50.0 million on the 2019 Revolving Credit Facility during the first quarter of 2020 to hold as cash on hand, 
$25.0 million of which was repaid during the fourth quarter of 2020. The remaining $25.0 million was repaid during 2021.

In conjunction with entering into the 2019 Revolving Credit Facility and the 2019 Term Loan, we drew down the entire $140.0 
million on the 2019 Term Loan and used those proceeds to pay off and close the 2018 Revolving Credit Facility of $58.5 
million, paid down a portion of the 2018 Term Loan of $56.0 million, paid the accrued interest associated with the amounts 
being paid down on the 2018 Revolving Credit Facility and 2018 Term Loan, paid the fees related to this transaction, and the 

63

 
 
 
 
 
Table of Contents

remainder used for general corporate expenses. The $56.0 million pay down on the 2018 Term Loan paid all the required 
quarterly installment payments on the 2018 Term Loan until maturity. 

The 2019 Term Loan and 2018 Term Loan were considered a modification of debt and thus, no gain or loss was recorded. 
Instead, the new fees paid to the lenders of $0.6 million were capitalized and are being amortized over the life of the 2019 Term 
Loan. The remaining debt issuance costs related to the 2018 Term Loan of $1.5 million as of the modification date will 
continue to be amortized over its remaining life. 

The 2019 Revolving Credit Facility that replaced the 2018 Revolving Credit Facility was considered an extinguishment of debt 
except for the portion related to the creditors that were part of both the 2019 Revolving Credit Facility and the 2018 Revolving 
Credit Facility and in which case, it was considered a modification of debt. As a result, we expensed the portion of the 
unamortized debt issuance costs related to the 2018 Revolving Credit Facility that was considered an extinguishment of debt of 
$0.5 million. In addition, the new fees paid to the lenders of $0.5 million as part of the 2019 Revolving Credit Facility were 
capitalized and are being amortized over its remaining life. Further, the remaining debt issuance costs related to the 2018 
Revolving Credit Facility of $1.1 million will also be amortized over its remaining life.

On December 16, 2021, we acquired 100.0% of the outstanding equity interests of Magnetic Seal LLC (f/k/a Magnetic Seal 
Corporation, “MagSeal”) for a purchase price of $69.5 million, net of cash acquired, all payable in cash. Upon the closing of the 
transaction, we paid a gross total aggregate of $71.3 million in cash, $65.0 million of which was from drawing down on the 
2019 Revolving Credit Facility. This draw down on the 2019 Revolving Credit Facility was paid off by December 31, 2021. 
See Note 2.

Also on December 16, 2021, we entered into a sale-leaseback transaction for the building and related land for our Gardena 
performance center located in Carson, California, for a sale price of $143.1 million. A portion of the net proceeds were used to 
pay down on the $65.0 million that was drawn on the 2019 Revolving Credit Facility for the MagSeal acquisition. See Note 5.

As of December 31, 2021, we had $99.8 million of unused borrowing capacity under the 2019 Revolving Credit Facility, after 
deducting $0.2 million for standby letters of credit.

The Credit Facilities were entered into by us (“Parent Company”) and guaranteed by all of our domestic subsidiaries, other than 
two subsidiaries that were considered minor (“Subsidiary Guarantors”). The Subsidiary Guarantors jointly and severally 
guarantee the Credit Facilities. The Parent Company has no independent assets or operations and therefore, no consolidating 
financial information for the Parent Company and its subsidiaries are presented.

On November 29, 2021, we entered into derivative contracts, U.S. dollar-one month LIBOR forward interest rate swaps 
designated as cash flow hedges, all with an effective date of January 1, 2024, for an aggregate total notional amount of 
$150.0 million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 (“Forward Interest Rate Swaps”). 
The Forward Interest Rate Swaps mature on a monthly basis, with fixed amount payer payment dates on the first day of each 
calendar month, commencing on February 1, 2024 through January 1, 2031. The Forward Interest Rate Swaps were deemed to 
be highly effective upon entering into the derivative contracts and thus, hedge accounting treatment was utilized. Since the 
Forward Interest Rate Swaps are not effective until January 1, 2024, we only recorded the changes in the fair value of the 
Forward Interest Rate Swaps and recorded in other long term liabilities and in other comprehensive income (loss) of 
$1.7 million as of December 31, 2021. See Note 1 for further information.

In October 2015, we entered into interest rate cap hedges designated as cash flow hedges with a portion of these interest rate 
cap hedges maturing on a quarterly basis, and a final quarterly maturity date of June 2020, in aggregate, totaling $135.0 million 
of our debt. We paid a total of $1.0 million in connection with entering into the interest rate cap hedges. The interest rate cap 
hedges matured during our second quarter of 2020 and as such, all remaining amounts related to the interest rate cap hedges 
were fully amortized and unrealized gains and losses recorded in accumulated other comprehensive income were also realized 
at that time. See Note 1 for further information.

Note 9. Shareholders’ Equity

We are authorized to issue five million  shares of preferred stock. At December 31, 2021 and 2020, no preferred shares were 
issued or outstanding.

Note 10. Stock-Based Compensation

Stock Incentive Compensation Plans

We currently have two active stock incentive plans: i) the 2020 Stock Incentive Plan (the “2020 Plan”), which expires on May 
6, 2030, and ii) the 2018 Employee Stock Purchase Plan (“ESPP”). The 2013 Stock Incentive Plan, as Amended (the “2013 

64

 
Table of Contents

Plan”) was closed to further issuances of stock awards on May 6, 2020 and any remaining shares available were folded into the 
2020 Plan as part of the approval of the 2020 Plan by shareholders at the 2020 Annual Meeting of Shareholders on May 6, 
2020. The 2020 Plan permit awards of stock options, restricted stock units, performance stock units and other stock-based 
awards to our officers, key employees and non-employee directors on terms determined by the Compensation Committee of the 
Board of Directors (the “Compensation Committee”). The aggregate number of shares available for issuance under the 2020 
Plan is 651,162 plus any outstanding awards issued under the 2013 Plan that are subsequently forfeited, terminated, expire or 
otherwise lapse without being exercised. As of December 31, 2021, shares available for future grant under the 2020 Plan are 
113,579. Prior to the adoption of the 2020 Plan, we granted stock-based awards to purchase shares of our common stock under 
certain predecessor plans. No further awards can be granted under these predecessor plans.

Employee Stock Purchase Plan

The ESPP was adopted by the Board of Directors and approved by the shareholders in 2018, including 750,000 shares that can 
be awarded. The first offering period closed on July 31, 2019. Under the ESPP, our employees who elect to participate have the 
right to purchase common stock at a 15% discount from the lower of the market value of the common stock at the beginning or 
the end of each six month offering period and the discount will be treated as compensation to those employees. Employees 
purchase common stock using payroll deductions, which may not exceed 10% of their eligible compensation and other 
limitations. The Compensation Committee administers the ESPP. As of December 31, 2021, there are 609,670 shares available 
for future award grants.

Stock Options

In the years ended December 31, 2021, 2020, and 2019, we granted stock options to our officers and key employees of zero, 
8,000, and 189,170, respectively, with weighted-average grant date fair values of zero, $16.48, and $15.95, respectively. Stock 
options have been granted with an exercise price equal to the fair market value of our stock on the date of grant and expire not 
more than ten years from the date of grant. The stock options typically vest over a period of three or four years from the date of 
grant. The option price and number of shares are subject to adjustment under certain dilutive circumstances. If an employee 
terminates employment, the non-vested portion of the stock options will not vest and all rights to the non-vested portion will 
terminate completely.

The aggregate intrinsic value of stock options represents the amount by which the market price of our common stock exceeds 
the exercise price of the stock option. The aggregate intrinsic value of stock options exercised for the years ended December 31, 
2021, 2020 and 2019 was $1.0 million, $0.9 million, and $1.8 million, respectively. Cash received from stock options exercised 

65

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

for the years ended December 31, 2021, 2020 and 2019 was $1.7 million, $1.6 million, and $2.0 million, respectively, with 
related tax benefits of $0.4 million, $0.4 million, and $0.5 million, respectively. The total amount of stock options vested and 
expected to vest in the future is 317,779 shares with a weighted-average exercise price of $35.30 and an aggregate intrinsic 
value of $3.5 million. These stock options have a weighted-average remaining contractual term of 5.7 years.

The share-based compensation cost expensed for stock options for the years ended December 31, 2021, 2020, and 2019 (before 
tax benefits) was $1.2 million, $1.8 million, and $1.6 million, respectively, and is included in selling, general and administrative 
expenses on the consolidated income statements. At December 31, 2021, total unrecognized compensation cost (before tax 
benefits) related to stock options of $0.4 million is expected to be recognized over a weighted-average period of 0.5 years. The 
total fair value of stock options vested during the years ended December 31, 2021, 2020, and 2019 was $1.7 million, $2.0 
million, and $1.3 million, respectively.

We apply fair value accounting for stock-based compensation based on the grant date fair value estimated using a Black-
Scholes-Merton (“Black-Scholes”) valuation model. The assumptions used to compute the fair value of stock option grants 
under the Stock Incentive Plans for years ended December 31, 2021, 2020, and 2019 were as follows:

Risk-free interest rate

Expected volatility

Expected dividends

We recognize compensation expense, net of an estimated forfeiture rate, on a straight-line basis over the requisite service period 
of the award. We have award populations with option vesting terms of three and four years. We estimate the forfeiture rate 
based on our historic experience, attempting to determine any discernible activity patterns. The expected life computation is 
based on historic exercise patterns and post-vesting termination behavior. The risk-free interest rate for periods within the 
contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is 
derived from historical volatility of our common stock. We suspended payments of dividends after the first quarter of 2011.

Restricted Stock Units

We granted restricted stock units (“RSUs”) to certain officers, key employees and non-employee directors of 118,995, 118,835, 
and 62,520 RSUs during the years ended December 31, 2021, 2020, and 2019, respectively, with weighted-average grant date 
fair values (equal to the fair market value of our stock on the date of grant) of $55.92, $27.62, and $41.04 per share, 
respectively. RSUs represent a right to receive a share of stock at future vesting dates with no cash payment required from the 
holder. The RSUs typically have a three year vesting term of 33%, 33% and 34% on the first, second and third anniversaries of 
the date of grant, respectively. If an employee terminates employment, their non-vested portion of the RSUs will not vest and 
all rights to the non-vested portion will terminate. 

Restricted stock unit activity for the year ended December 31, 2021 was as follows:

benefits) was $4.1 million, $2.6 million, and $2.4 million respectively, and is included in selling, general and administrative 
expenses on the consolidated income statements. At December 31, 2021, total unrecognized compensation cost (before tax 
benefits) related to RSUs of $5.6 million is expected to be recognized over a weighted average period of 1.7 years. The total fair 
value of RSUs vested for the years ended December 31, 2021, 2020, and 2019 was $4.2 million, $2.3 million, and $2.4 million, 
respectively. The tax benefit realized from vested RSUs for the years ended December 31, 2021, 2020, and 2019 was $1.0

Performance Stock Units

We granted performance stock awards (“PSUs”) to certain key employees of 182,886, 159,136, and 58,178 PSUs during the 
years ended December 31, 2021, 2020, and 2019, respectively, with weighted-average grant date fair values of $49.76, $29.65, 
and $43.80 per share, respectively. PSU awards are subject to the attainment of performance goals established by the 
Compensation Committee, the periods during which performance is to be measured, and all other limitations and conditions 
applicable to the awarded shares. Performance goals are based on a pre-established objective formula that specifies the manner 
of determining the number of PSUs that will be granted if performance goals are attained. If an employee terminates 
employment, their non-vested portion of the PSUs will not vest and all rights to the non-vested portion will terminate. 

Performance stock activity for the year ended December 31, 2021 was as follows:

benefits) related to PSUs of $7.0 million is expected to be recognized over a weighted-average period of 1.5 years. The total fair 
value of PSUs vested during the years ended December 31, 2021, 2020, and 2019, was $9.6 million, $3.7 million, and $3.8 
million, respectively. The tax benefit realized from PSUs for the years ended December 31, 2021, 2020, and 2019 were $2.3 
million, $0.9 million, and $0.9 million, respectively.

Note 11. Employee Benefit Plans

Supplemental Retirement Plans

We have three unfunded supplemental retirement plans. The first plan was suspended in 1986, but continues to cover certain 
former executives. The second plan was suspended in 1997, but continues to cover certain current and retired directors. The 
third plan covers certain current and retired employees and further employee contributions to this plan were suspended on 
August 5, 2011. The liability for the third plan and interest thereon is included in accrued employee compensation and long-
term liabilities were both zero at December 31, 2021, and zero and $0.1 million, respectively, at December 31, 2020. The 
accumulated benefit obligations of the first two plans at December 31, 2021 and December 31, 2020 were both $0.3 million, 
and are included in accrued liabilities.

Defined Contribution 401(k) Plans

We sponsor a 401(k) defined contribution plan for all our employees. The plan allows the employees to make annual voluntary 
contributions not to exceed the lesser of an amount equal to 25% of their compensation or limits established by the Internal 
Revenue Code. Under this plan, we generally provide a match equal to 50% of the employee’s contributions up to the first 6% 
of compensation, except for union employees who are not eligible to receive the match. Our provision for matching and profit 
sharing contributions for the three years ended December 31, 2021, 2020, and 2019 was $2.8 million, $2.6 million, and $2.7 
million, respectively.

Other Plans

We have a defined benefit pension plan covering certain hourly employees of a subsidiary (the “Pension Plan”). Pension Plan 
benefits are generally determined on the basis of the retiree’s age and length of service. Assets of the Pension Plan are 
composed primarily of fixed income and equity securities. We also have a retirement plan covering certain current and retired 
employees (the “LaBarge Retirement Plan”). As part of the acquisition of CTP, we acquired their defined benefit pension plan 
(the “CTP Pension Plan”), which covered certain current and retired employees that were fully funded by CTP as of the 
acquisition date in April 2018. The CTP Pension Plan was suspended as of the acquisition date but continued to cover certain 
current and former CTP employees. The CTP Pension Plan gross assets, liabilities, and current year expense were immaterial

for disclosure purposes. The CTP Pension Plan was subsequently liquidated in November 2019 with no loss recorded as a 
pension plan escrow fund was established as part of the acquisition to cover any losses until it was liquidated.

(1) Projected benefit obligation equals the accumulated benefit obligation for the plans.

On December 31, 2021, our annual measurement date, the accumulated benefit obligation exceeded the fair value of the plans 
assets by $6.1 million. Such excess is referred to as an unfunded accumulated benefit obligation. We recorded unrecognized 
loss included in accumulated other comprehensive loss, net of tax at December 31, 2021 and 2020 of $5.7 million and $9.6 
million, respectively, which decreased shareholders’ equity. This charge to shareholders’ equity represents a net loss not yet 
recognized as pension expense. This charge did not affect reported earnings, and would be decreased or be eliminated if either 
interest rates increase or market performance and plan returns improve which will cause the Pension Plan to return to fully 
funded status.

Our Pension Plan asset allocations at December 31, 2021 and 2020, by asset category, were as follows:

Pension Plan assets consist primarily of listed stocks and bonds and do not include any of the Company’s securities. The return 
on assets assumption reflects the average rate of return expected on funds invested or to be invested to provide for the benefits 
included in the projected benefit obligation. We select the return on asset assumption by considering our current and target asset 
allocation. We consider information from various external investment managers, forward-looking information regarding 
expected returns by asset class and our own judgment when determining the expected returns.

(1) Represents mutual funds and commingled accounts which invest primarily in equities, but may also hold fixed income 
securities, cash and other investments. Commingled funds with publicly quoted prices and actively traded are classified 
as Level 1 investments.

Pooled funds are measured using the net asset value (“NAV”) as a practical expedient for fair value as permissible under the 
accounting standard for fair value measurements and have not been categorized in the fair value hierarchy in accordance with 
ASU 2015-07, “Fair Value Measurement (Topic 820):  Disclosures for Investments in Certain Entities That Calculate Net Asset 
Value per Share (or Its Equivalent).” Pooled fund NAVs are provided by the trustee and are determined by reference to the fair 
value of the underlying securities of the trust, less its liabilities, which are valued primarily through the use of directly or 
indirectly observable inputs. Depending on the pooled fund, underlying securities may include marketable equity securities or 
fixed income securities.

The assumptions used to determine the benefit obligations and expense for our two plans are presented in the tables below. The 
expected long-term return on assets, noted below, represents an estimate of long-term returns on investment portfolios 
consisting of a mixture of fixed income and equity securities. The estimated cash flows from the plans for all future years are 
determined based on the plans’ population at the measurement date. We used the expected benefit payouts from the plans for 
each year into the future and discounted them back to the present using the Wells Fargo yield curve rate for that duration.

The weighted-average assumptions used to determine the net periodic benefit costs under the two plans were as follows:

Our funding policy is to contribute cash to our plans so that the minimum contribution requirements established by government

Note 12. Indemnifications

We have made guarantees and indemnities under which we may be required to make payments to a guaranteed or indemnified 
party, in relation to certain transactions, including revenue transactions in the ordinary course of business. In connection with 
certain performance center leases, we have indemnified our lessors for certain claims arising from the performance center or the 
lease. We indemnify our directors and officers to the maximum extent permitted under the laws of the State of Delaware.

However, we have a directors and officers insurance policy that may reduce our exposure in certain circumstances and may 
enable us to recover a portion of future amounts that may be payable, if any. The duration of the guarantees and indemnities 
varies and, in many cases is indefinite but subject to statute of limitations. The majority of guarantees and indemnities do not 
provide any limitations of the maximum potential future payments we could be obligated to make. Historically, payments 
related to these guarantees and indemnities have been immaterial. We estimate the fair value of our indemnification obligations 
as insignificant based on this history and insurance coverage and have, therefore, not recorded any liability for these guarantees 
and indemnities in the accompanying consolidated balance sheets.

We have federal and state tax net operating losses of $15.1 million and $18.2 million, respectively, as of December 31, 2021. 
The federal net operating losses acquired from the acquisition of Nobles are subject to an annual limitation under Internal 
Revenue Code Section 382; however, we expect to fully realize them under ASC Subtopic 740-10 before they begin to expire 
in 2033. The state net operating loss carryforwards include $10.7 million that is not expected to be realized due to various 
limitations and has been reduced by a valuation allowance. If not realized, the state net operating loss carryforwards, depending 
on the tax jurisdiction, will begin to expire between 2027 and 2038. 

We have federal and state tax credit carryforwards of $0.1 million and $10.9 million, respectively, as of December 31, 2021. A 
valuation allowance of $9.0 million has been provided on state tax credit carryforwards that are not expected to be realized 
under ASC Subtopic 740-10. If not realized, the federal tax carryforwards will begin to expire in 2032 and state tax credit 
carryforwards, depending on the tax jurisdiction, will begin to expire between 2022 and 2036. 

We believe it is more likely than not that we will generate sufficient taxable income to realize the benefit of the remaining 
deferred tax assets.

Our total amount of unrecognized tax benefits was $4.4 million, $4.1 million, and $5.7 million at December 31, 2021, 2020, 
and 2019, respectively. We record interest and penalty charges, if any, related to uncertain tax positions as a component of tax 
expense and unrecognized tax benefits. The amounts accrued for interest and penalty charges as of December 31, 2021, 2020, 
and 2019 were not significant. If recognized, $2.6 million would affect the effective income tax rate. As a result of statute of 
limitations set to expire in 2022, we expect decreases to our unrecognized tax benefits of approximately $0.7 million in the next 
twelve months.

A reconciliation of the beginning and ending amount of unrecognized tax benefits was as follows:

Additions for tax positions related to prior years

We file U.S. Federal and state income tax returns. We are subject to examination by the Internal Revenue Service (“IRS”) for 
tax years after 2017 and by state taxing authorities for tax years after 2016. While we are no longer subject to examination prior 
to those periods, carryforwards generated prior to those periods may still be adjusted upon examination by the IRS or state 
taxing authorities if they either have been or will be used in a subsequent period. We believe we have adequately accrued for 
tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.

In March 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) that provided tax 
relief to individuals and businesses affected by the coronavirus pandemic. We considered the provisions of the CARES Act and 
determined they do not have a material impact on our overall income taxes. We utilized the option to defer payment of the 
employer portion of payroll taxes (Social Security) that would otherwise be required to be made during the period beginning 
March 27, 2020 to December 31, 2020. As such, as of December 31, 2020, we deferred payment of income tax deductions 
related to payroll taxes of $6.1 million and recorded the related deferred tax asset of $1.4 million, which was included as part of 
the net deferred income taxes on the consolidated balance sheet. We were required to and made the payments for 50% of the 
deferred payroll taxes by December 31, 2021. As of December 31, 2021, the remaining unpaid deferred income tax deductions 
related to payroll taxes is $3.1 million and the related deferred tax asset of $0.7 million is included as part of the net deferred 
income taxes on the consolidated balance sheet.

In December 2020, the U.S. enacted the Consolidated Appropriations Act, 2021 (“Appropriations Act”) that provided 
additional tax relief to individuals and businesses affected by the coronavirus pandemic. We considered the provisions of the 
Appropriations Act and determined they do not have a material impact to our overall income taxes.

On March 11, 2021, the U.S. enacted the American Rescue Plan Act of 2021 (“Rescue Plan”). The amendment to Section 
162(m) expanding the definition of covered employee to also include the next five highest compensated employees in the 
limitation will apply to us effective January 1, 2027. We do not expect any tax impacts to be material. We considered other 
provisions in the Rescue Plan and determined they have no or minimal impact to our overall income taxes.

The Tax Cuts and Jobs Act of 2017 (“TCJA”), which was signed into U.S. law in December 2017, eliminated the option to 
immediately deduct research and development expenditures in the year incurred under Section 174 effective January 1, 2022. 
The amended provision under Section 174 requires us to capitalize and amortize these expenditures over five years. Although 
there is proposed legislation to temporarily reinstate the current deduction of the expenditures after 2021 through 2025, we must 
consider the changes under the TCJA. If the provision is not deferred, modified, or repealed, with retroactive effect to January 
1, 2022, it may result in a material impact on cash from operating activities and the balance of our deferred taxes. The actual 
impact will depend on if and when this provision is deferred, modified, or repealed by Congress, including if retroactively to 
January 1, 2022, and the amount of research and development expenditures incurred in 2022. We are monitoring legislation for 
any further changes to Section 174 and the impact to the financial statements in 2022.

Note 14. Commitments and Contingencies

In December 2020, a representative action under California’s Private Attorneys General Act was filed against us in the Superior 
Court for the State of California, County of San Bernardino. We received service of process of this complaint on January 28, 
2021. The complaint alleges violations of California’s wage and hour laws relating to our current and former employees and 
seeks attorney’s fees and penalties. We vigorously refuted and defended these claims, and reached a tentative settlement of 
$0.8 million during the fourth quarter 2021, which is subject to court approval. Thus, we recorded accrued liabilities of 
$0.8 million as of December 31, 2021.

Structural Systems has been directed by California environmental agencies to investigate and take corrective action for 
groundwater contamination at our facilities located in El Mirage and Monrovia, California. Based on currently available 
information, we have established an accrual for its estimated liability for such investigation and corrective action of $1.5 
million as of both December 31, 2021 and December 31, 2020, which is reflected in other long-term liabilities on our 
consolidated balance sheets.

Structural Systems also faces liability as a potentially responsible party for hazardous waste disposed at landfills located in 
Casmalia and West Covina, California. Structural Systems and other companies and government entities have entered into 
consent decrees with respect to these landfills with the United States Environmental Protection Agency and/or California 
environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based 
on currently available information, we preliminarily estimate that the range of our future liabilities in connection with the 
landfill located in West Covina, California is between $0.4 million and $3.1 million. We have established an accrual for the 
estimated liability in connection with the West Covina landfill of $0.4 million as of both December 31, 2021 and December 31, 
2020, which is reflected in other long-term liabilities on our consolidated balance sheets. Our ultimate liability in connection 
with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost 
of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.

In June 2020, a fire severely damaged our performance center in Guaymas, Mexico, which is part of our Structural Systems 
segment. There were no injuries, however, property and equipment, inventories, and tooling in this leased facility were 
damaged. Our Guaymas performance center is comprised of two buildings with an aggregate total of 62,000 square feet. The 
loss of production from the Guaymas performance center is being absorbed by our other existing performance centers. A 
neighboring, non-related manufacturing facility, also suffered fire damage during the same time as the fire that severely 
damaged our Guaymas performance center. The cause of the fire is still undetermined and as such, there is no amount of loss 
that is probable and reasonably estimable at this time. 

Our insurance covers damage to the facility, equipment, unfinished inventory, and other assets at replacement cost, finished 
goods inventory at selling price, as well as business interruption, third party property damage, and recovery related expenses 
caused by the fire, less our per claim deductible. The anticipated insurance recoveries related to losses and incremental costs 
incurred are recognized when receipt is probable. The anticipated insurance recoveries in excess of net book value of the 
damaged operating assets and business interruption will not be recorded until all contingencies related to our claim have been 
resolved. During the year ended December 31, 2020, $0.8 million of revenue and $0.5 million of related cost of sales were 
reversed for revenue previously recognized using the over time method as the revenue recognition process for these items were 
deemed to be interrupted as a result of these inventory items being damaged. Also during the year ended December 31, 2020, 
we wrote off property and equipment and tooling with an aggregate total net book value of $7.1 million and inventory on hand 
of $3.4 million that were damaged by the fire. The related anticipated insurance recoveries were also presented within the same 
financial statement line item in the consolidated statements of income resulting in no net impact, with the anticipated insurance 
recoveries receivable included as part of other current assets on the consolidated balance sheets. As of December 31, 2021,

$13.5 million of general insurance recoveries have been received to date. The timing of and the remaining amounts of insurance 
recoveries, including for business interruption, are not known at this time.

In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and inquiries, 
including matters relating to environmental laws. In addition, Ducommun makes various commitments and incurs contingent 
liabilities in the ordinary course of business. While it is not feasible to predict the outcome of these matters, Ducommun does 
not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse 
effect on its consolidated financial position, results of operations or cash flows.

Note 15. Major Customers and Concentrations of Credit Risk

We provide proprietary products and services to the Department of Defense and various United States Government agencies, 
and most of the aerospace and aircraft manufacturers who receive contracts directly from the U.S. Government as an original 
equipment manufacturer (“Primes”). In addition, we also service technology-driven markets in the industrial, medical and other 
end-use markets. As a result, we have significant net revenues from certain customers. Accounts receivable were diversified 
over a number of different commercial, military and space programs and were made by both operating segments. Net revenues 
from our top ten customers, including The Boeing Company (“Boeing”), Lockheed Martin Corporation (“Lockheed Martin”), 
Northrop Grumman Corporation (“Northrop”), Raytheon Technologies Corporation (“Raytheon”), and Spirit AeroSystems 
Holdings, Inc. (“Spirit”), represented the following percentages of total net revenues:

In 2021, 2020 and 2019, net revenues from foreign customers based on the location of the customer were $43.6 million, $58.5 
million and $81.6 million, respectively. No net revenues from a foreign country were greater than 3.0% of total net revenues in 
2021, 2020, and 2019. We have manufacturing facilities in Thailand and Mexico. Our net revenues, profitability and 
identifiable long-lived assets attributable to foreign revenues activity were not material compared to our net revenues, 
profitability and identifiable long-lived assets attributable to our domestic operations during 2021, 2020, and 2019. We are not 
subject to any significant foreign currency risks as all our sales are made in United States dollars.

Note 16. Business Segment Information

We supply products and services primarily to the aerospace and defense industries. Our subsidiaries are organized into two 
strategic businesses, Electronic Systems and Structural Systems, each of which is an operating segment as well as a reportable 
segment.

On December 16, 2021, we acquired 100.0% of the outstanding equity interests of MagSeal for a purchase price of $69.5 
million, net of cash acquired. We allocated the preliminary gross purchase price of $71.3 million to the assets acquired and 
liabilities assumed at their estimated fair values. The excess of the purchase price over the aggregate fair values of the net assets 
was recorded as goodwill. See Note 2.
