Leverage the TriMas Business Model.We implemented theThe TriMas Business Model ("TBM") in late 2016serves as the platform to improvemanage our diverse set of businesses under a common set of standards focused on driving long-term exceptional performance. Through the management and performance of our businesses. The TBM, provides a platform towe set near- and long-term performance objectives and goals, including safety, financial, and talent development, measure these against defined objectives, and utilize a reliable communication and escalation process that provides for flexibility and adjustments if market expectations change. We believe the TBM connects our operations, and allows us to benefit from sharing best practices across each of our businesses. We believe that the TBM, through a culture of Kaizen and continuous improvement, helps drive long-term improvement in our performance. For example, since August 2016, we have rationalized 13 manufacturing, warehousing and office locations, streamlined fixed expenses and selling, general and administrative expenses in certain of our businesses, increased our focus on optimizing inventory levels and improved certain of our manufacturing processes. We believe actions driven by the TBM have provided an economic benefit to us and have augmented our cash conversion characteristics and performance overall. Specifically, we reduced our debt from $374.7 million at December 31, 2016 to $293.6 million at December 31, 2018, and we ended 2018 with $108.2 million of cash and cash equivalents on the balance sheet. We will continue to rely on the TBM to drive continuous improvement and to unlock TriMas’ value potential.

Effective with the first quarter of 2019, we will report the machined components operations, located in Stanton, California and Tolleson, Arizona, in the Specialty Products segment. Prior to this change, it has been reported in the Aerospace segment. This modification allows us to better leverage our machining competencies and resources across the businesses within the Specialty Products segment, as well as provides us with the opportunity to expand sales of these products to customers outside of the aerospace market. In addition, this change enables our TriMas Aerospace team to better focus on driving growth and innovation in our aerospace fastener and related product lines.
In addition, effective with the first quarter of 2018, we realigned our reportable segment structure from four segments to three. While there were no changes to the Packaging and Aerospace segments, we combined the former Energy and Engineered Components segments into a single segment, titled Specialty Products. This change was made in connection with our business realignment efforts, to provide a more streamlined operating structure and to better leverage resources across the Norris Cylinder, Lamons and Arrow Engine businesses.

Competitive Strengths
We believe RiekeTriMas Packaging benefits from the following competitive strengths:strengths in coordination with operating under TriMas' overarching strategy:
Strong Product Innovation. Through a multi-layered approach to product and process innovation starting with subject matter experts, our TriMas Packaging team is focused on driving innovation across a broad range of solutions for our customers. Our New Product Development teams are also supported by our Engineering Resource Center ("ERC"), located in India, to enhance our technical innovation and development. TriMas Packaging has a consistent pipeline of new products ready for launch and continues to innovate to make products more sustainable and environmentally friendly. For example, TriMas Packaging's product development programs have provided innovative and proprietary product solutions, such as the patented single-polymer MonoTM-2e pump, which features six parts, all made from one material, making it 100% recyclable. We are also developing additional dispensing products made from a single-material without compromising quality, aesthetics, performance or formula compatibility, under the SingoloTMbrand. In addition, TriMas Packaging partnered with Amazon to develop a range of products designed to meet the requirements of the high-growth e-commerce retail channel, including a proprietary dispenser locking mechanism to protect the integrity of packages and prevent liquids from leaking during shipment, meeting consumers' demands and ISTA 6 standards as required by Amazon. TriMas Packaging's emphasis on highly-engineered solutions and product development has yielded numerous issued and enforceable patents, with many other patent applications pending. For example, 44 patents were filed and 64 patents were issued in 2021, related to both new and existing patent families.
Strong Product Innovation. We believe that Rieke’s product development capability is a competitive advantage. Through its Global Innovation Centers located in the United States, United Kingdom and India, Rieke is focused on driving innovation across a broad range of dispensing and closure solutions for its customers. Rieke’s product development programs have provided innovative and proprietary product solutions, such as the Visegrip® steel flange and plug closure, and the all-plastic, environmentally safe, self-venting FlexSpout® flexible pouring spout. Rieke, partnering with Amazon, also developed a range of products designed to meet the requirements of the high-growth e-commerce retail channel, including a proprietary dispenser locking mechanism to protect the integrity of packages and prevent liquids from leaking during shipment. As a result of this innovation, Rieke was honored as a Diamond Finalist for Packaging Innovation by Dow Chemical in 2018 for the development of a new lotion dispensing pump for e-commerce solutions. Other developments include a measured-dose dispenser that provides exact doses of highly-concentrated liquids for the health and beauty market. Rieke’s emphasis on highly-engineered solutions and product development has yielded numerous issued and enforceable patents, with many other patent applications pending.

Over the past few years, Rieke has increased its global manufacturing and sales presence, with advanced manufacturing capabilities in China, India, Vietnam and Mexico. We have also increased our sales coverage in Europe and Asia, and in January 2019, closed on the acquisition of Plastic Srl, a manufacturer of polymeric caps and closures for home care product applications, located in Forlì, Italy, which provides us with additional manufacturing capacity and sales presence in Europe. By maintaining a presence in international locations, Rieke focuses on developing new markets and new applications for its products, capitalizing on its global design and manufacturing capabilities.

Marketing, Customers and Distribution
The primary customers of our Specialty Products businessessegment predominantly operate in the industrial end markets, and to a lesser extent, the upstream oil and gas industrial and commercial end markets. Given the focused nature of many of our products, we rely upon a combination of a direct sales force and an established network of distributors with familiarity of the end-users. Lamons,Norris Cylinder, for example, relies upon a combination of a direct sales force and an established network of independent distributors and licensees. The close proximity of the sales and distribution network to the customer makes it possible for Lamons to respond to customer-specific engineered applications and provide a high degree of customer service. Norris Cylinder also sells directly to customers and through distributors.

Lamons' primary manufacturing facility and the majority of sales and service locations are located in the United States, with additional locations in Belgium, Canada, Singapore, Spain and Thailand.States.
Competition
Norris Cylinder competes against Worthington, Beijing Tianhai Industry Co., Faber and Vitkovice Cylinders, but is the only remaining steel cylinder manufacturer in the United States. In May 2012, the U.S. International Trade Commission made a unanimous final determination that Norris Cylinder had been materially injured by imports of DOT high-pressure steel cylinders that were being subsidized by the Government of China, as well as being dumped in the U.S. market by producers in China. As a result, trade duties were imposed on the subject imports for a five-year period to create a fairer competitive environment in the United States. The duty was extended and increased for an additional five-year period in 2017, and will be subject to renewal in 2022. We believe Lamons offers a broader gasket and bolt product portfolio than its competitors, as most tend to focus on either gaskets or bolts, but not both. Also, there is a wide range of end markets that consume gasket and bolt products, and Lamons primarily serves midstream and downstream petrochemical and refinery applications. As such, Lamons competes with a wide variety of companies depending on geography and product content, including ERIKS, Flexitallic Group, Garlock (EnPro), GHX, Klinger and Lone Star, but rarely is directly competing with another company across all products.2017. Arrow Engine tends to compete against natural gas powered, lower horsepower, multi-cylinder engines from manufacturers such as Caterpillar, Chevy, Cummins and Ford industrial engines and electric motors.

Government Regulations
Environmental Matters
We are subject to increasingly stringent environmental laws and regulations, including those relating to air emissions, wastewater discharges, and chemical and hazardous waste management and disposal. Some of these environmental laws hold owners or operators of land or businesses liable for their own and for previous owners' or operators' releases of hazardous or toxic substances or wastes. Other environmental laws and regulations require the obtainmentobtaining and compliancecomplying with environmental permits. To date, costs of complying with environmental, health and safety requirements have not been material. However, the nature of our operations and our long history of industrial activities at certain of our current or former facilities, as well as those acquired, could potentially result in material environmental liabilities.
Current environmental laws and regulations have not had a material impact on our business, capital expenditures or financial position. However, we must comply with existing and pending climate change legislation, regulation and international treaties or accords. Future events, including those relating to climate change or greenhouse gas regulation could require us to incur expenses related to the modification or curtailment of operations, installation of pollution control equipment or investigation and cleanup of contaminated sites. In addition to environmental laws and regulations, our operations are governed by variety of laws and regulations, including those relating to workplace safety and worker health, principally the Occupational Safety and Health Act and regulations thereunder. We believe that we are in material compliance with these laws and regulations and do not believe that future compliance with such laws and regulations will have a material adverse effect on our business, financial condition, results of operations and cash flows.

Trade Policies and Regulations
13

TableFree trade laws and regulations provide certain duties and tariffs on qualifying imports and exports, subject to compliance with the applicable classification and other requirements. In the past few years, we have experienced higher input costs as a direct result of Contentstariffs imposed on certain raw materials and components imported from China. In certain cases, we have passed-through these incremental costs to the customer, while in some cases we have not changed pricing to retain or expand volume, and in other cases we continue to work to install capacity in facilities where there currently is no tariff. In addition, certain of our U.S. suppliers raised prices for components in response to an overall increase in demand for domestic sources. 


We believe that we are in material compliance with free trade laws and regulations. While there may be an impact to our financial condition as a result of changes in the amount of duties or tariffs levied on products we sell, we do not believe that costs to remain in compliance with such laws and regulations will have a material adverse effect on our business, financial condition, results of operations and cash flows.
Intangible Assets
Our identified intangible assets, consisting of customer relationships, trademarks and trade names, and technology, are recorded at approximately $174.5$196.7 million at December 31, 2018,2021, net of accumulated amortization.

Useful lives assigned to customer relationship intangibles range from five to 25 years and have been estimated using historic customer retention and turnover data. Other factors considered in evaluating estimated useful lives include the diverse nature of focused markets and products of which we have significant share, how customers in these markets make purchases and these customers' position in the supply chain. We also monitor and evaluate the impact of other evolving risks including the threat of lower cost competitors and evolving technology.
Trademarks and Trade Names. Each of our businesses designs and manufactures products for focused markets under various trade names and trademarks (see prior discussion above by reportable segment). Our trademark/trade name intangibles are well-established and considered long-lived assets that require maintenance through advertising and promotion expenditures. Because it is our practice and intent to maintain and to continue to support, develop and market these trademarks/trade names for the foreseeable future, we consider our rights in these trademarks/trade names to have an indefinite life, except as otherwise dictated by applicable law.
13

Technology. We hold a number of United States and foreign patents, patent applications, and proprietary product and process-oriented technologies within all three of our reportable segments. We have, and will continue to dedicate, technical resources toward the further development of our products and processes in order to maintain our competitive position in the industrial, commercial and consumer end markets that we serve. Estimated useful lives for our technology intangibles range from one to 30 years and are determined in part by any legal, regulatory or contractual provisions that limit useful life. For example, patent rights have a maximum limit of 20 years in the United States. Other factors considered include the expected use of the technology by the operating groups, the expected useful life of the product and/or product programs to which the technology relates, and the rate of technology adoption by the industry.
International Operations
Approximately 13.9%25.3% of our net sales for the year ended December 31, 20182021 were derived from sales by our businesses located outside of the United States, and we may expand our international operations through organic growth actions and acquisitions. In addition, approximately 15.8%37.1% of our long-lived assets as of December 31, 20182021 were located outside of the United States. We operate manufacturing facilities in Belgium, Canada, China, Germany, India, Italy, (as a result of the January 2019 acquisition of Plastic Srl), Mexico, Singapore, Spain, Thailand,Slovakia, the United Kingdom and Vietnam.Vietnam, in addition to our U.S. operations. In addition to the net sales derived from sales by our businesses located outside of the United States, we also generated approximately $72.7$80.6 million of export sales from the United States. For information pertaining to the net sales and long-lived assets attributed to our international operations, refer to Note 18, "Segment Information," included in Item 8, "Financial Statements and Supplementary Data," within this Form 10-K.

Item 1A.    Risk Factors
You should carefully consider each of the risks described below, together with information included elsewhere in this Annual Report on Form 10-K and other documents we file with the SEC. The risks and uncertainties described below are those that we have identified as material, but are not the only risks and uncertainties facing us. Although the risks are organized by headings, and each risk is discussed separately, many of the risks are interrelated. Readers should not interpret the disclosure of any risk factor to imply that the risk has not already materialized. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial may also impact our business operations, financial results and liquidity.
Risks Relating to the COVID-19 Pandemic
The COVID-19 pandemic has had, and is expected to continue to have, a significant impact on the Company's operations and results.
Since late January 2020, we have been managing matters related to the global COVID-19 pandemic, including impacts to our operations and strategic supplier-partners in Asia, as well as our manufacturing operations in Europe and North America. We have experienced temporary disruptions in the operation of certain of our facilities due to elevated levels of absenteeism, which has impacted workforce staffing. In response, we were early adopters of many of the workplace guidelines published by the U.S. Centers for Disease Control and Prevention ("CDC") and implemented other precautionary measures as necessary to maintain social distancing. The COVID-19 pandemic has also affected our customers and suppliers, and we have been and will continue to collaborate with them to minimize supply chain disruptions. We have also implemented pandemic and business continuity plans, as well as other precautionary measures on behalf of our customers and employees, including supporting remote work opportunities for certain of our employees. While we believe that all of these measures have been necessary and appropriate, they have resulted in additional costs and may adversely impact our business and financial performance in the future or expose us to additional unknown risks.
The COVID-19 pandemic has impacted our results of operations, and we expect it will continue to impact us in the future at varying levels. For example, sales for our dispensing and closure products used to help fight the spread of gems continue to be much stronger than before the COVID-19 pandemic, while sales in our Aerospace segment have been lower than historical levels as a result of the reduction of new commercial aircraft builds. Although it is not possible to predict the ultimate impact of COVID-19, including on our business, results of operations, financial position or cash flows, such impacts that have been or may be material and include, but are not limited to: (i) shifting customer demand for many of our products, including those used in cosmetic, personal care, pharmaceutical, home care, food and beverage, and industrial markets, as well as aerospace markets; (ii) delays and disruptions in the availability of and timely delivery of materials and components used in our operations, as well as increased costs for such materials and components; (iii) reduced availability and productivity of employees, as well as increased costs associated with our high-deductible medical insurance plan if our employees become ill; (iv) increased operational risks as a result of manufacturing facility disruptions or remote work arrangements, including the potential effects on internal controls and procedures, as well as cybersecurity risks and increased vulnerability to security breaches, information technology disruptions and other similar events; (v) increased credit risk, including increased failure by customers experiencing business disruptions to make timely payments; (vi) customer requirements to accelerate the relocation of certain of our production lines to North America, which may increase our capital investment needs and launch costs; (vii) a negative impact on liquidity position; (viii) any impairment in value of tangible or intangible assets which could be recorded as a result of weaker economic conditions; and (ix) increased costs and less ability to access amounts available under our existing credit facility or more generally, access to and the availability of capital markets.
The extent of the COVID-19 pandemic's effect on our operational and financial performance will depend in large part on future developments, which cannot be predicted with confidence at this time. Future developments include the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact, and the resumption of widespread economic activity, including air travel. The emergence of new variants of COVID-19, evolving governmental plans to institute vaccination mandates and limited availability of vaccines in various jurisdictions create uncertainty that may impact our employees and result in labor shortages and unforeseen costs. In addition, because we cannot predict the impact that COVID-19 will ultimately have, the actual impact may also exacerbate other risks discussed in this Item 1A.

Risks Relating to Our Business
Our businesses depend upon general economic conditions and we serve some customers in highly cyclical industries; as such, we may be subject to the loss of sales and margins due to an economic downturn or recession.
Our financial performance depends, in large part, on conditions in the markets that we serve in both the U.S. and global economies. Someglobally. Although with the sale of our Lamons business ("Lamons") in December 2019 we significantly reduced our exposure to the oil and gas end markets thatmarket, we servestill are exposed to highly cyclical such as the end markets for industrial goods (including our remaining exposure in oil and gas products and industrial goods,gas), and to a lesser extent, aerospace and consumer products. When combined with ongoing customer consolidation activity and periodic inventory reduction initiatives, an uncertain macro-economic and political climate could lead to reduced demand from our customers, variations in timing of sales to our customers, increased price competition for our products, increased risk of excess and obsolete inventories, uncollectible receivables, and higher overhead costs as a percentage of revenue, all of which could impact our operating margins. If our customers are adversely affected by these factors, we may experience lower product volume orders, which could have an unfavorable impact on our revenue and operating profit. Our inabilityability to precisely forecast precisely the level of our customers’ orders is limited and can causeresult in inefficiencies withinin scheduling our installed manufacturing capacity and result in sub-optimal business and financial results.
Many of the markets we serve are highly competitive, which could limit sales volumes and reduce our operating margins.
Many of our products are sold in competitive markets. We believe that the principal points of competition in our markets are price, product quality, delivery performance, design and engineering capabilities, product development, conformity to customer specifications, customer service and effectiveness of distribution. Maintaining and improving our competitive position will require continued investment by us in manufacturing, engineering, quality standards, marketing, customer service and support of our distribution networks. We may have insufficient resources in the future to continue to make such investments and, even if we make such investments, we may not be able to maintain or improve our competitive position. We also face the risk of lower-cost manufacturers located in China, India and other regions competing in the markets for our products and we may be driven as a consequence of this competition to increase our investment overseas. Making overseas investments can be highly complicated and we may not always realize the advantages we anticipate from any such investments. Competitive pressure may limit the volume of products that we sell and reduce our operating margins.
We may be unable to successfully implement our business strategies and achieve our strategic and financial objectives.
We have a long history of acquisitions and divestitures, and we continuously evaluate strategic opportunities and other investment activities. From time to time, we may engage in one or more strategic transactions. If we do so, it may or may not meet the intended strategic or financial objective.
Strategic acquisitions may require integration expense and actions that may negatively affect our results of operations and that could not have been fully anticipated beforehand. In addition, attractive strategic transaction opportunities may not be identified or pursued in the future, financing for strategic transactions may be unavailable on satisfactory terms and we may be unable to accomplish our strategic objectives in effecting a particular strategic transaction. We may encounter various risks in pursuing such strategic transactions, including the possible inability to integrate an acquired business into our operations, increased expenses, increased debt obligations to finance such strategic transactions and unanticipated problems or liabilities.
In addition, we may dispose of assets or businesses at a price or on terms that are less favorable than we had anticipated, or with the exclusion of assets that must be divested or run off separately. As we seek to sell or separate certain assets, equity interests or businesses, we may also encounter difficulty in finding buyers, managing interdependencies across multiple transactions and other Company initiatives, implementing separation plans or executing alternative exit strategies on acceptable terms, which could delay or prevent the accomplishment of our strategic and financial objectives. Moreover, the effect of dispositions over time will reduce our cash flow and earnings capacity and result in a less diversified portfolio of businesses, and we will have a greater dependency on remaining businesses for our financial results.
Accordingly, risks related to strategic acquisitions or dispositions may result in the disruption of our ongoing business, diversion of management’s attention, the failure of such transactions to be completed, or the failure to realize the financial and strategic benefits contemplated at the time of a transaction, some or all of which could materially and adversely affect our business strategy, financial condition and results of operations.

We have significant goodwill and intangible assets, and future impairment of our goodwill and intangible assets could have a material negative impact on our financial results.
At December 31, 2021, our goodwill and intangible assets were approximately $512.2 million and represented approximately 39.3% of our total assets. If we experience declines in sales and operating profit or do not meet our current and forecasted operating budget, we may be subject to goodwill and/or other intangible asset impairments in the future. While the fair value of our remaining goodwill exceeds its carrying value, significantly worse financial performance of our businesses, significantly different assumptions regarding future performance of our businesses or significant declines in our stock price could result in future impairment losses. Because of the significance of our goodwill and intangible assets, and based on the magnitude of historical impairment charges, any future impairment of these assets could have a material adverse effect on our financial results.
Increases in our raw material or energy costs or the loss of critical suppliers could adversely affect our profitability and other financial results.
We are sensitive to price movements in our raw materials supply base. Our largest material purchases are for resins (such as polypropylene and polyethylene), steel, aluminum and other oil and metal-based purchased components. Prices for these products, along with costs for transportation and energy, fluctuate with market conditions, and have generally increased over time. For example, during 2021, commodity costs related to certain types of resins significantly increased from prior years, and we estimate that we incurred approximately $11 million more in cost increases than we were able to recover via commercial actions. We may be unable to offset the impact with price increases on a timely basis due to outstanding commitments to our customers, competitive considerations or our customers’ resistance to accepting such price increases and our financial performance could be adversely impacted. A failure by our suppliers to continue to supply us with certain raw materials, component parts, or at all, could have a material adverse effect on us. To the extent there are energy supply disruptions or material fluctuations in energy costs, our margins could be materially adversely impacted.
Our business may be exposed to risks associated with an increasingly concentrated customer base.
While no individual customer accounted for 10% or more of our consolidated net sales for 2021, 2020 or 2019, our customer base has become, and may further become, increasingly concentrated as a result of our strategy to focus on grow sales with existing customers in packaging end markets, or due to customer consolidations. In 2021, our Aerospace and Specialty Products segments each had customers that comprised 10% or more of its segment revenue. As a result of these factors, changes to or reductions in the buying patterns of these larger customers may expose our business and results of operations to greater volatility. For example, prior to the outbreak of COVID-19, a large commercial aircraft manufacturer announced significant production delays and/or reductions on certain of its platforms for which we provide products, which has impacted our sales, profit and production efficiencies compared with historical levels.

The mix and type of customers, and sales to any single customer, may vary significantly from quarter to quarter and from year to year, and have a significant impact on our financial condition, results of operations and cash flows. If customers do not place orders, or they substantially reduce, delay or cancel orders, we may not be able to replace the business, which may have a significant adverse impact on our results of operations and financial condition. Major customers may require that we localize manufacturing and supply capacity rather than sourcing from lower cost countries, or seek pricing, payment, intellectual property-related, or other commercial terms that are less favorable to us, which may have a negative impact on our business. The concentration of our customer base also increases our risks related to the financial condition of our customers, and the deterioration in financial condition of customers or the failure of customers to perform their obligations could have a material adverse effect on our results of operations and cash flows.
We are dependent on our manufacturing facilities for the production of our highly engineered products, which subjects us to risks associated with disruptions and changing technology and manufacturing techniques that could place us at a competitive disadvantage.
If our manufacturing facilities become unavailable either temporarily or permanently due weather, earthquakes or other natural disasters related to labor disruptionsglobal climate change, or circumstances beyond our control, such as geopolitical developments or logistical complications arising from acts of war, cyber-attacks, weather, global climate change, earthquakespublic health crises or other natural disasters,labor disruptions, we may be unable to shift production to other facilities or to make up for lost production. For example, our Aerospace manufacturing facilities are predominately located in southern California, an area known for earthquakes, and are thus vulnerable to damage. Any new facility would need to comply with the necessary regulatory requirements, satisfy our specialized manufacturing requirements and require specialized equipment. Even though we carry business interruption insurance policies, any business interruption losses could exceed the coverage available or be excluded from our insurance policies. Any disruption of our ability to operate our business could result in a material decrease in our revenues or significant additional costs to replace, repair or insure our assets, which could have a material adverse impact on our financial condition and results of operations.

In addition, we believe that our customers rigorously evaluate their suppliers on the basis of price competitiveness, product quality, reliability and timeliness of delivery, technical expertise and development capability, new product innovation, product design capability, manufacturing expertise, operational flexibility, customer service and overall management. Our success depends on our ability to continue to meet our customers’ changing expectations with respect to these criteria. We may be unable to install, maintain and certify equipment needed to produce products or upgrade or transition our manufacturing facilities without impacting production rates or requiring other operational efficiency measures at our facilities. We anticipate that we will remain committed to product research and development, advanced manufacturing techniques and service to remain competitive, which entails significant costs; however, we may be unable to address technological advances, implement new and more cost-effective manufacturing techniques, or introduce new or improved products, whether in existing or new markets, so as to maintain our businesses’ competitive positions or to grow our businesses as desired.
Many of the markets we serve are highly competitive, which could limit sales volumes and reduce our operating margins.
Many of our products are sold in competitive markets. We believe that the principal points of competition in our markets are price, product quality, delivery performance, design and engineering capabilities, product development, conformity to customer specifications, customer service and effectiveness of distribution.

We may have insufficient resources in the future to continue to make such investments and, even if we make such investments, we may not be able to maintain or improve our competitive position. We also face the risk of lower-cost foreign manufacturers located in China, Southeast Asia, India and other regions competing in the markets for our products and we may be driven as a consequence of this competition to increase our investment overseas. Making overseas investments can be highly complicated and we may not always realize the advantages we anticipate from any such investments. Competitive pressure may limit the volume of products that we sell and reduce our operating margins.

We may be unable to successfully implement our business strategies.
We have a long history of acquisitions and divestitures, and we continuously evaluate strategic opportunities and other investment activities. From time to time, we may engage in one or more strategic transactions. If we do so, it may or may not meet the intended strategic objective. These strategic transactions may require integration expense and actions that may negatively affect our results of operations and that could not have been fully anticipated beforehand. In addition, attractive strategic transaction opportunities may not be identified or pursued in the future, financing for strategic transactions may be unavailable on satisfactory terms and we may be unable to accomplish our strategic objectives in effecting a particular strategic transaction. We may encounter various risks in pursuing such strategic transactions, including the possible inability to integrate an acquired business into our operations, the disruption of our ongoing business, diversion of management’s attention, increased expenses, increased debt obligations to finance such strategic transactions, unanticipated problems or liabilities, the failure of such transactions to be completed, or the failure to realize the financial and strategic benefits contemplated at the time of a transaction, some or all of which could materially and adversely affect our business strategy and financial condition and results of operations.
Trends in oil and natural gas prices may affect the demand for, and profitability of, our energy-related products and services, which could have a material adverse effect on our business, consolidated results of operations, and consolidated financial condition.
The oil and gas industry historically has experienced periodic downturns. Demand for our energy-related products, such as pump jack engines and compressors, gaskets, fasteners, hoses and compression products is sensitive to the level of production activity of, and the corresponding capital spending by, oil and natural gas companies. The level of production activity is directly affected by trends in oil (and related derivatives) and natural gas prices, which have been at lower levels over the past three years, and may continue to remain at depressed levels and be subject to future volatility.
Prices for oil and natural gas are subject to large fluctuations in response to changes in the supply of and demand for oil and natural gas, market uncertainty, geopolitical developments, alternative production methods and a variety of other factors that are beyond our control. Even the perception of longer-term lower oil and natural gas prices can reduce or defer major capital expenditures by our customers in the oil and gas industry. Given the long-term nature of many large-scale development projects, a significant or extended downturn in the oil and gas industry could result in the reduction in demand for our energy-related products, and could have a material adverse effect on our business, consolidated results of operations and consolidated financial condition.
Compliance with and changes in tax laws, including tax reform legislation in the United States, could materially and adversely impact our financial condition, results of operations and cash flows.

We are subject to extensive tax liabilities, including federal, state and foreign income taxes and transactional taxes such as excise, sales and use, payroll, franchise, withholding and property taxes. Many tax liabilities are subject to periodic audits by taxing authorities, and such audits could subject us to additional tax as well as interest and penalties. New tax laws and regulations and changes in existing tax laws and regulations could result in increased expenditures by us for tax liabilities in the future and could materially and adversely impact our financial condition, results of operations and cash flows.
The 2017 Tax Cuts and Jobs Act included substantial changes to U.S. tax law, including a reduction in the corporate tax rate, a limitation on deductibility of interest expense, a limitation on the use of net operating losses to offset future taxable income, the allowance of immediate expensing of capital expenditures and deemed repatriation of foreign earnings. The Company recorded charges of approximately $12.3 million, net, between 2017 and 2018 as a result of adopting the 2017 Tax Cuts and Jobs Act. Any future clarification of the tax law or required change in these charges could adversely affect the Company's business and financial condition.
Increases in our raw material or energy costs or the loss of critical suppliers could adversely affect our profitability and other financial results.
We are sensitive to price movements in our raw materials supply base. Our largest material purchases are for steel, polyethylene and other resins, aluminum, titanium and copper. Prices for these products fluctuate with market conditions, and have generally increased over time. We may be unable to offset the impact with price increases on a timely basis due to outstanding commitments to our customers, competitive considerations or our customers’ resistance to accepting such price increases and our financial performance could be adversely impacted. A failure by our suppliers to continue to supply us with certain raw materials or component parts on commercially reasonable terms, or at all, could have a material adverse effect on us. To the extent there are energy supply disruptions or material fluctuations in energy costs, our margins could be materially adversely impacted.

Our business may be exposed to risks associated with an increasingly concentrated customer base.
While no individual customer accounted for 10% or more of our consolidated net sales for 2018, 2017 or 2016, our customer base has become, and may further become, increasingly concentrated as a result of customer consolidations and/or through our sales growth to new and existing customers. In 2018, our Packaging and Aerospace reportable segments each had either one or two customers that comprised more than 10% of its segment revenue. As a result of these factors, certain customers may expose our business and results of operations to greater volatility. The mix and type of customers, and sales to any single customer, may vary significantly from quarter to quarter and from year to year, and have a significant impact on our financial condition, results of operations and cash flows. If customers do not place orders, or they substantially reduce, delay or cancel orders, we may not be able to replace the business, which may have a significant adverse impact on our results of operations and financial condition. Major customers may also seek pricing, payment, intellectual property-related, or other commercial terms that are less favorable to us, which may have a negative impact on our business. The concentration of our customer base also increases our risks related to the financial condition of our customers, and the deterioration in financial condition of customers or the failure of customers to perform their obligations could have a material adverse effect on our results of operations and cash flows.
A major failure of our information systems could harm our business; increased IT security threats and more sophisticated and targeted computer crime could pose a risk to our systems, networks, and products.
We depend on integrated information systems to conduct our business. While we maintain some of our critical information systems, we are also dependent on third parties to provide important services relating to, among other things, operational technology at our facilities, human resources, electronic communications and certain finance functions. We may experience operating problems with our information systems as a result of system failures, viruses, computer hackers or other causes. Any significant disruption or slowdown of our systems could cause customers to cancel orders or cause standard business processes to become inefficient or ineffective.

We have experienced cyber-attacks in the past and, while none of these cyber-attacks resulted in a material disruption to our business, we may experience additional cyber-attacks in the future. Increased global IT security threats and more sophisticated and targeted computer crime pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data and communications. While we attempt to mitigate these risks by employing a number of measures, including employee training, comprehensive monitoring of our networks and systems, and maintenance of backup and protective systems, our networks and systems remain potentially vulnerable to advanced persistent threats. Furthermore, we may have little or no oversight with respect to security measures employed by third-party service providers, which may ultimately prove to be ineffective at countering threats. Depending on their nature and scope, such threats could potentially lead to the compromising of confidential information and communications, improper use of our systems and networks, manipulation and destruction of data, defective products, production downtimes and operational disruptions, which in turn could adversely affect our reputation, competitiveness and results of operations.
Our ability to deliver products that satisfy customer requirements is dependent on the performance of our subcontractors and suppliers, as well as on the availability of raw materials and other components.
We rely on other companies, including subcontractors and suppliers, to provide and produce raw materials, integrated components and sub-assemblies and production commodities included in, or used in the production of, our products. If one or more of our suppliers or subcontractors experiences delivery delays or other performance problems, we may be unable to meet commitments to our customers or incur additional costs and penalties. In some instances, we depend upon a single source of supply. During 2021, we experienced many supply chain delays and inconsistencies with our subcontractors and suppliers as a result of the ongoing COVID-19 pandemic, resulting in labor and manufacturing inefficiencies given the challenges in production scheduling. Any material service disruption from one of these suppliers, either due to circumstances beyond the supplier’s control, such as geopolitical developments or logistical complications due to weather, global climate change, earthquakes or other natural disasters, or as a result of performance problems or financial difficulties, could have a material adverse effect on our ability to meet commitments to our customers or increase our operating costs.
A growing portion of our sales and earnings may be derived from international sources, which exposes us to certain risks which may adversely affect our financial results and impact our ability to service debt.
We have operations outside of the United States. Approximately 25.3% of our net sales for the year ended December 31, 2021 were derived from sales by our subsidiaries located outside of the U.S. In addition, we may expand our international operations through internal growth or acquisitions. International operations, particularly sales to emerging markets and manufacturing in non-U.S. countries, are subject to risks that are not present within U.S. markets, which include, but are not limited to, the following:
volatility of currency exchange between the U.S. dollar and currencies in international markets;

changes in local government regulations and policies including, but not limited to, foreign currency exchange controls or monetary policy, governmental embargoes, repatriation of earnings, expropriation of property, duty or tariff restrictions, investment limitations and tax policies;

political and economic instability and disruptions, including labor unrest, civil strife, public health crises (including viral outbreaks such as the coronavirus), acts of war, guerrilla activities, insurrection and terrorism;
legislation that regulates the use of chemicals;
disadvantages of competing against companies from countries that are not subject to U.S. laws and regulations, including the Foreign Corrupt Practices Act ("FCPA");
compliance with international trade laws and regulations, including export control and economic sanctions, such as anti-dumping duties;
difficulties in staffing and managing multi-national operations;
limitations on our ability to enforce legal rights and remedies;

tax inefficiencies in repatriating cash flow from non-U.S. subsidiaries that could affect our financial results and reduce our ability to service debt;        

reduced protection of intellectual property rights; and
other risks arising out of foreign sovereignty over the areas where our operations are conducted.  
In addition, we could be adversely affected by violations of the FCPA and similar worldwide anti-bribery laws as well as export controls and economic sanction laws. The FCPA and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business.
Our acquisition and disposition agreements by which we have acquired or sold companies, include indemnification provisions that may not fully protect us and may result in unexpected liabilities.
Certain of the agreements related to the acquisition and disposition of businesses require indemnification against certain liabilities related to the operations of the company for the previous owner. We cannot be assured that any of these indemnification provisions will fully protect us, and as a result we may incur unexpected liabilities that adversely affect our profitability and financial position.
We could be negatively impacted by stakeholder and market focus on ESG matters.
There has been an increasing focus on corporate ESG practices and disclosures over the past few years, and expectations in this area are rapidly evolving. We have announced certain areas of focus, which include health and safety, environmental matters, diversity, equity and inclusion, talent development, and innovation for sustainable products. The criteria used to evaluate ESG practices may continue to evolve, which could result in greater expectations and may cause us to undertake costly initiatives to satisfy new criteria. The increasing attention to sustainability could also result in reduced demand for certain of our products and/or reduced profits. If we are unable to respond effectively, investors may conclude that our ESG policies and/or actions are inadequate. If we are perceived to have failed to achieve our ESG initiatives or accurately disclose our progress on such matters, our reputation, business, financial condition and results of operations could be adversely impacted.

Regulatory, Legal and Environmental Risks
Significant developments from the recent and potential changes in U.S. trade policies could have a material adverse effect on us and our financial condition and results of operations.
Existing freeFree trade laws and regulations such as the North American Free Trade Agreement and/or other trade agreements, provide certain beneficial duties and tariffs on qualifying imports and exports, subject to compliance with the applicable classification and other requirements. The U.S.United States government has indicated its intent to alter its approach to international trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and treaties with foreign countries. For example, throughoutbeginning in October 2018, the U.S. government implemented additional tariffs on certain goods imported from China. These tariffs, and other governmental actions relating to international trade agreements or policies, the adoption and expansion of trade restrictions, or the occurrence of a trade war may adversely impact demand for our products, costs, customers, suppliers and/or the U.S. economy or certain sectors thereof and, as a result, adversely impact our business. These tariffs and actions may, directly or indirectly, lead to higher costs and cause us to increase prices to our customers which may reduce demand, or, if we are unable to increase prices, result in lowering our margin on products sold.  For example, in 2018,the past few years, we have experienced higher input costs as a direct result of recentlytariffs imposed tariffs on certain raw materials and components imported from China. In certain cases, we have passed-through these incremental costs to the customer, while in some cases we have not changed pricing to retain or expand volume, and in other cases we continue to work to install capacity in facilities where there currently is no tariff. In addition, certain of our U.S. suppliers raised prices for certain components in response to an overall increase in demand for domestic sources as a result of recently imposed tariffs.sources.  It remains unclear what the U.S. or foreign governments will or will not do with respect to tariffs, international trade agreements and policies on a short-term or long-term basis. Additional changes in laws or policies governing the terms of foreign trade, and in particular increased trade restrictions, tariffs or taxes on imports from countries where we manufacture or purchase products could have a material adverse effect on our business and financial results.

Our ability to deliver products that satisfy customer requirements is dependent on the performance of our subcontractorsCompliance with and suppliers, as well as on the availability of raw materials and other components.
We rely on other companies,changes in tax laws, including subcontractors and suppliers, to provide and produce raw materials, integrated components and sub-assemblies and production commodities included in, or usedtax reform legislation in the production of, our products. If one or more of our suppliers or subcontractors experiences delivery delays or other performance problems, we may be unable to meet commitments to our customers or incur additional costsUnited States, could materially and penalties. In some instances, we depend upon a single source of supply. Any service disruption from one of these suppliers, either due to circumstances beyond the supplier’s control, such as geopolitical developments or logistical complications due to weather, global climate change, earthquakes or other natural disasters, or as a result of performance problems or financial difficulties, could have a material adverse effect on our ability to meet commitments to our customers or increase our operating costs.
We have significant goodwill and intangible assets, and future impairment of our goodwill and intangible assets could have a material negativeadversely impact on our financial results.
At December 31, 2018, our goodwill and intangible assets were approximately $491.2 million and represented approximately 44.6% of our total assets. Based on thecondition, results of our annual goodwill and indefinite-lived intangible asset impairment tests, we recorded pre-tax goodwill and indefinite-lived intangible asset impairment charges in 2016 of approximately $98.9 million within our Aerospace reporting unit. If we experience declines in sales and operating profit or do not meet our current and forecasted operating budget, we may be subject to additional goodwill and/or other intangible asset impairments in the future. While the fair value of our remaining goodwill exceeds its carrying value, significantly worse financial performance of our businesses, significantly different assumptions regarding future performance of our businesses or significant declines in our stock price could result in future impairment losses. Because of the significance of our goodwill and intangible assets, and based on the magnitude of historical impairment charges, any future impairment of these assets could have a material adverse effect on our financial results.
We have debt principal and interest payment requirements that may restrict our future operations and impair our ability to meet our obligations.cash flows.
As of December 31, 2018, we have approximately $293.6 million of outstanding debt. We are subject to variableextensive tax liabilities, including federal, state and foreign income taxes and transactional taxes such as excise, sales and use, payroll, franchise, withholding and property taxes. Many tax liabilities are subject to periodic audits by taxing authorities, and such audits could subject us to additional tax as well as interest rates on our revolving credit facility. We may experience increases in our interest expense as a result of general increases in interest rate levels. We have no amounts outstanding under our revolving credit facility as of December 31, 2018.
Our degree of leverage and level of interest expense may have important consequences, including:
should our leverage increase, it may place us at a competitive disadvantage as compared with our less leveraged competitorspenalties. New tax laws and make us more vulnerable in the event of a downturn in general economic conditions or in any of our businesses;
our flexibility in planning for, or reacting to,regulations and changes in our businessesexisting tax laws and the industriesregulations could result in which we operate may be limited;
a substantial portion of our cash flow from operations will be dedicated to the payment of annual interest and future principal obligations on our indebtedness, thereby reducing the funds available toincreased expenditures by us for operations, capital expenditures, acquisitions, future business opportunities or obligations to pay rent in respect of our operating leases; and
our operations are restricted by our debt instruments, which contain certain financial and operating covenants, and those restrictions may limit, among other things, our ability to borrow moneytax liabilities in the future for working capital, capital expenditures, acquisitions, rent expense or other purposes.
Our ability to service our debt and other obligations will depend on our future operating performance, which will be affected by prevailing economic conditions and financial, business and other factors, many of which are beyond our control. Our business may not generate sufficient cash flow, and future financings may not be available to provide sufficient net proceeds, to meet these obligations or to successfully execute our business strategies. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources."

Restrictions in our debt instruments limit our ability to take certain actions and breaches thereof could impair our liquidity.
Our revolving credit facility and the indenture governing our senior notes contain covenants that restrict our ability to:
pay dividends or redeem or repurchase capital stock;
incur additional indebtedness and grant liens;
make acquisitions and joint venture investments; and
sell assets.
Our debt instruments also require us to comply with financial covenants relating to, among other things, interest coverage and leverage. We may not be able to satisfy these covenants in the future or be able to pursue our strategies within the constraints of these covenants. Substantially all of the assets of our domestic subsidiaries are pledged as collateral. Borrowings under the foreign currency sub limit are secured by a pledge of the assets of the foreign subsidiary borrowers that are party to our revolving credit facility. A breach of a covenant contained in our debt instruments could result in an event of default under one or more of our debt instruments and our lease financing arrangements. Such breaches would permit the lenders to declare all amounts borrowed thereunder to be due and payable, and the commitments of such lenders to make further extensions of credit could be terminated. Each of these circumstances could materially and adversely impairimpact our liquidity.financial condition, results of operations and cash flows.
We may face liability associated with the use of products for which patent ownership or other intellectual property rights are claimed.
We may be subject to claims or inquiries regarding alleged unauthorized use of a third party’s intellectual property. An adverse outcome in any intellectual property litigation could subject us to significant liabilities to third parties, require us to license technology or other intellectual property rights from others, require us to comply with injunctions to cease marketing or using certain products or brands, or require us to redesign, re-engineer, or re-brand certain products or packaging, any of which could affect our business, financial condition and operating results. If we are required to seek licenses under patents or other intellectual property rights of others, we may not be able to acquire these licenses on acceptable terms, if at all. In addition, the cost of responding to an intellectual property infringement claim, in terms of legal fees and expenses and the diversion of management resources, whether or not the claim is valid, could have a material adverse effect on our business, results of operations and financial condition.
We may be unable to adequately protect our intellectual property.
While we believe that our patents, trademarks, know howknow-how and other intellectual property have significant value, it is uncertain that this intellectual property or any intellectual property acquired or developed by us in the future, will provide a meaningful competitive advantage. Our patents or pending applications may be challenged, invalidated or circumvented by competitors or rights granted thereunder may not provide meaningful proprietary protection. Moreover, competitors may infringe on our patents or successfully avoid them through design innovation. Policing unauthorized use of our intellectual property is difficult and expensive, and we may not be able to, or have the resources to, prevent misappropriation of our proprietary rights, particularly in countries where the laws may not protect such rights as fully as in the U.S. The cost of protecting our intellectual property may be significant and have a material adverse effect on our financial condition and future results of operationsoperations.

We may incur material losses and costs as a result of product liability, recall and warranty claims brought against us.
We are, from time to time, subject to a variety of claims or litigation incidental to our businesses, including claimsdemands for damages arising out of use of our products, claims relating to intellectual property matters and claims involving employment matters and commercial disputes. We currently carry insurance and maintain reserves for potential product liability claims. However, our insurance coverage may be inadequate if such claims do arise and any liability not covered by insurance could have a material adverse effect on our business. Although we have been able to obtain insurance in amounts we believe to be appropriate to cover such liability to date, our insurance premiums may increase in the future as a consequence of conditions in the insurance business generally or our situation in particular. Any such increase could result in lower operating profit or cause the need to reduce our insurance coverage. In addition, a future claim may be brought against us that could have a material adverse effect on us. Any product liability claim may also include the imposition of punitive damages, the award of which, pursuant to certain state laws, may not be covered by insurance. Our product liability insurance policies have limits that, if exceeded, may result in material costs that could have an adverse effect on our future profitability. In addition, warranty claims are generally not covered by our product liability insurance. Further, any product liability or warranty issues may adversely affect our reputation as a manufacturer of high-quality, safe products, divert management’s attention, and could have a material adverse effect on our business.

In addition, theour former Lamons business within our Specialty Products reportable segment is a party to lawsuits related to asbestos contained in gaskets formerly manufactured by it or its predecessors. While we sold the Lamons business in December 2019, we retained the asbestos-related liability exposure. Some of this litigation includes claims for punitive and consequential as well as compensatory damages. We are not able to predict the outcome of these matters given that, among other things, claims may be initially made in jurisdictions without specifying the amount sought or by simply stating the minimum or maximum permissible monetary relief, and may be amended to alter the amount sought. Of the 4,8204,754 claims pending at December 31, 2018, 492021, 27 set forth specific amounts of damages (other than those stating the statutory minimum or maximum). See Note 13,17, "Commitments and Contingencies," included in Item 8, "Financial Statements and Supplementary Data," within this Form 10-K for additional information.
Total settlement costs (exclusive of defense costs) for all such cases, some of which were filed over 25 years ago, have been approximately $8.9$10.6 million. All relief sought in the asbestos cases is monetary in nature. To date, approximately 40% of our costs related to settlement and defense of asbestos litigation have been covered by our primary insurance. Effective February 14, 2006, we entered into a coverage-in-place agreement with our first level excess carriers regarding the coverage to be provided to us for asbestos-related claims when the primary insurance is exhausted. The coverage-in-place agreement makes asbestos defense costs and indemnity insurance coverage available to us that might otherwise be disputed by the carriers and provides a methodology for the administration of such expenses. The Company's primary insurance exhausted in November 2018, and the Company will beis solely responsible for defense costs and indemnity payments prior to the commencement of coverage under this agreement, the duration of which would be subject to the scope of damage awards and settlements paid. During this period, we may incur significant litigation costs in defending these matters. We also may be required to incur additional defense costs and pay damage awards or settlements or become subject to equitable remedies in the future that could adversely affect our businesses.
Our business may be materially and adversely affected by compliance obligations and liabilities under environmental laws and regulations.regulations, including related to climate change.
We are subject to increasingly stringent environmental laws and regulations, including those relating to air emissions, wastewater discharges and chemical and hazardous waste management and disposal. A number of governments or governmental bodies have introduced or are contemplating introducing regulatory changes in response to climate change, including regulating greenhouse gas emissions. Some of these environmental laws hold owners or operators of land or businesses liable for their own and for previous owners’ or operators’ releases of hazardous or toxic substances or wastes. Other environmental laws and regulations require the obtainmentobtaining and compliancecomplying with environmental permits. To date, costs of complying with environmental, health and safety requirements have not been material. However, the nature of our operations and our long history of industrial activities at certain of our current or former facilities, as well as those acquired, could potentially result in material environmental liabilities.
While we must comply with existing and pending climate change legislation, regulation and international treaties or accords, current laws and regulations have not had a material impact on our business, capital expenditures or financial position. Future events, including those relating to climate change or greenhouse gas regulation, could require us to incur expenses related to fund energy efficiency activities, fees or restrictions on certain activities, the modification or curtailment of operations, installation of pollution control equipment or investigation and cleanup of contaminated sites. Any adopted future regulations could also negatively impact our ability to compete with companies situated in areas not subject to such limitations, and we may not be able to recover the cost of compliance with new or more stringent laws and regulations, which could adversely impact our results of operations, cash flow or financial condition.

Our reputation, ability to do business, and results of operations may be impaired by legal compliance risks.
While we strive to maintain high standards, our internal controls and compliance systems may not always protect us from acts committed by our employees, agents, or business partners that would violate U.S. and/or non-U.S. laws or adequately protect our confidential information, including the laws governing payments to government officials, bribery, fraud, anti-kickback and false claims rules, competition, export and import compliance, money laundering, and data privacy laws, as well as the improper use of proprietary information or social media. Any such allegations, violations of law or improper actions could subject us to civil or criminal investigations in the U.S. and in other jurisdictions, could lead to substantial civil or criminal, monetary and non-monetary penalties, and related shareholder lawsuits, could lead to increased costs of compliance, could damage our reputation and could have a material effect on our financial statements.
Risks Related to our Debt and Other Financial Obligations
We have debt principal and interest payment requirements that may restrict our future operations and impair our ability to meet our obligations.
As of December 31, 2021, we have approximately $393.8 million of outstanding long-term debt. We are subject to variable interest rates on our revolving credit facility. Such interest rates are based on the London Interbank Offered Rate ("LIBOR") plus 1.50%. We may experience increases in our interest expense as a result of general increases in interest rate levels. In addition, we could be further impacted by changes in variable interest rates. Although we have amended our credit facility to utilize the Secured Overnight Financing Rate ("SOFR") beginning in 2022, SOFR has a limited history and may perform differently from U.S. dollar LIBOR, which may affect our net interest expense and require changes to our future risk, pricing and hedging strategies. We had no amounts outstanding under our revolving credit facility as of December 31, 2021.
Our degree of leverage and level of interest expense may have important consequences, including:
should our leverage increase, it may place us at a competitive disadvantage as compared with our less leveraged competitors and make us more vulnerable in the event of a downturn in general economic conditions or in any of our businesses;
our flexibility in planning for, or reacting to, changes in our businesses and the industries in which we operate may be limited;
a substantial portion of our cash flow from operations will be dedicated to the payment of annual interest and future principal obligations on our indebtedness, thereby reducing the funds available to us for operations, capital expenditures, acquisitions, future business opportunities or obligations to pay rent in respect of our operating leases; and
our operations are restricted by our debt instruments, which contain certain financial and operating covenants, and those restrictions may limit, among other things, our ability to borrow money in the future for working capital, capital expenditures, acquisitions, rent expense or other purposes.
Our ability to service our debt and other obligations will depend on our future operating performance, which will be affected by prevailing economic conditions and financial, business and other factors, many of which are beyond our control. Our business may not generate sufficient cash flow, and future financings may not be available to provide sufficient net proceeds, to meet these obligations or to successfully execute our business strategies. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources."

Our debt instruments also require us to comply with financial covenants relating to, among other things, interest coverage and leverage. We may not be able to satisfy these covenants in the future or be able to pursue our strategies within the constraints of these covenants. Substantially all of the assets of our domestic subsidiaries are pledged as collateral. Borrowings under the foreign currency sub limit are secured by a pledge of the assets of the foreign subsidiary borrowers that are party to our revolving credit facility. A breach of a covenant contained in our debt instruments could result in an event of default under one or more of our debt instruments and our lease financing arrangements. Such breaches would permit the lenders to declare all amounts borrowed thereunder to be due and payable, and the commitments of such lenders to make further extensions of credit could be terminated. Each of these circumstances could materially and adversely impair our liquidity.
Our borrowing costs may be impacted by our credit ratings developed by various rating agencies.
Two major ratings agencies, Standard & Poor’s and Moody’s, evaluate our credit profile on an ongoing basis and have each assigned ratings for our long-term debt. If our credit ratings were to decline, our ability to access certain financial markets may become limited, the perception of us in the view of our customers, suppliers and security holders may worsen and as a result, we may be adversely affected.
We have significant operating lease obligations and our failure to meet those obligations could adversely affect our financial condition.
We lease many of our manufacturing and distribution branch facilities, and certain capital equipment. Our rental expense in 20182021 under these operating leases was approximately $12.3$11.0 million. A failure to pay our rental obligations would constitute a default allowing the applicable landlord to pursue any remedy available to it under applicable law, which would include taking possession of our property and, in the case of real property, evicting us. These leases are categorized as operating leases and are not considered indebtedness for purposes of our debt instruments.

Human Capital Risks

TableWe depend on the services of Contentskey individuals and relationships, the loss of which could materially harm us.


Our success will depend, in part, on the efforts of our key leadership, including key operational, technical, commercial, manufacturing and financial personnel. Our business leadership teams have served a vast majority of their careers in, and are deeply experienced in, the industries we operate. Our future success will also depend on, among other factors, our ability to retain or attract other qualified personnel. The loss of the services of any of our key employees or the failure to retain or attract employees could have a material adverse effect on us.
We may be subject to further unionization and work stoppages at our facilities or our customers may be subject to work stoppages, which could seriously impact the profitability of our business.
As of December 31, 2018,2021, we have one facility, located in Commerce, California, where our hourly employees operate under a collective bargaining agreement, and which represents approximately 16%14% of our work force was unionized under several different unions and bargaining agreements. We have collective bargaining agreements covering four facilities worldwide, two of which areemployees located in the United States. We have four facilities outside of the United States where our employees are affiliated with state-controlled or trade unions, which covers approximately 47% of our non-U.S. employees. Our labor agreement with the United Automobile, Aerospace and Agricultural Implement Workers of America at our TriMas Aerospace facility in Commerce, California, expired in August 2021, at which time we entered into a new three-year collective bargaining agreement. We are not aware of any present active union organizing drives at any of our other facilities. We cannot predict the impact of any further unionization of our workplace. Our labor agreement with the United Automobile, Aerospace and Agricultural Implement Workers of America at our TriMas Aerospace facility in Commerce, California expired during 2018, at which time we revised the collective bargaining agreement which now extends until 2021.
Many of our direct or indirect customers have unionized work forces. Strikes, work stoppages or slowdowns experienced by these customers or their suppliers could result in slowdowns or closures of assembly plants where our products are included.utilized. In addition, organizations responsible for shipping our customers' products may be impacted by occasional strikes or other activity. Any interruption in delivery of our customers' products may reduce demand for our products and have a material adverse effect on us.
Healthcare costs for active employees may exceed projections and may negatively affect our financial results.
We maintain a range of healthcare benefits for our active employees pursuant to labor contracts and otherwise. Healthcare benefits for active employees are provided through comprehensive hospital, surgical and major medical benefit provisions or through health maintenance organizations, all of which are subject to various cost-sharing features. Some of these benefits are provided for in fixed amounts negotiated in labor contracts with the respective unions. If our costs under our benefit programs for active employees exceed our projections, our business and financial results could be materially adversely affected. Additionally, foreign competitors and many domestic competitors provide fewer benefits to their employees, and this difference in cost could adversely impact our competitive position.
A growing portion of our sales may be derived from international sources, which exposes us to certain risks which may adversely affect our financial results and impact our ability to service debt.
23
We have operations outside of the United States. Approximately 13.9% of our net sales for the year ended December 31, 2018 were derived from sales by our subsidiaries located outside of the U.S. In addition, we may expand our international operations through internal growth or acquisitions. International operations, particularly sales to emerging markets and manufacturing in non-U.S. countries, are subject to risks that are not present within U.S. markets, which include, but are not limited to, the following:
volatility of currency exchange between the U.S. dollar and currencies in international markets;

changes in local government regulations and policies including, but not limited to, foreign currency exchange controls or monetary policy, governmental embargoes, repatriation of earnings, expropriation of property, duty or tariff restrictions, investment limitations and tax policies;
political and economic instability and disruptions, including labor unrest, civil strife, acts of war, guerrilla activities, insurrection and terrorism;
legislation that regulates the use of chemicals;
disadvantages of competing against companies from countries that are not subject to U.S. laws and regulations, including the Foreign Corrupt Practices Act ("FCPA");
compliance with international trade laws and regulations, including export control and economic sanctions, such as anti-dumping duties;
difficulties in staffing and managing multi-national operations;
limitations on our ability to enforce legal rights and remedies;

tax inefficiencies in repatriating cash flow from non-U.S. subsidiaries that could affect our financial results and reduce our ability to service debt;        

reduced protection of intellectual property rights; and
other risks arising out of foreign sovereignty over the areas where our operations are conducted.

In addition, we could be adversely affected by violations of the FCPA and similar worldwide anti-bribery laws as well as export controls and economic sanction laws. The FCPA and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business.
Our acquisition and disposition agreements by which we have acquired or sold companies, include indemnification provisions that may not fully protect us and may result in unexpected liabilities.
Certain of the agreements related to the acquisition and disposition of businesses require indemnification against certain liabilities related to the operations of the company for the previous owner. We cannot be assured that any of these indemnification provisions will fully protect us, and as a result we may incur unexpected liabilities that adversely affect our profitability and financial position.
We depend on the services of key individuals and relationships, the loss of which could materially harm us.
Our success will depend, in part, on the efforts of our key leadership, including key technical, commercial and manufacturing personnel. Our future success will also depend on, among other factors, our ability to retain or attract other qualified personnel. The loss of the services of any of our key employees or the failure to retain or attract employees could have a material adverse effect on us.
Economic conditions and regulatory changes leading up to and following the United Kingdom's anticipated exit from the European Union could have a material adverse effect on our business and results of operations.
The United Kingdom's anticipated exit from the European Union and the resulting significant change to the United Kingdom's relationship with the European Union and with countries outside the European Union (and the laws, regulations and trade deals impacting business conducted between them) could disrupt the overall economic growth or stability of the United Kingdom and the European Union and negatively impact our operations. The United Kingdom is currently negotiating the terms of the anticipated exit, with the United Kingdom due to exit the European Union on March 29, 2019. There is significant uncertainty about the terms and timing under which the United Kingdom will leave the European Union. These developments, or the perception that any of them could occur, have had and may continue to have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global market liquidity and restrict the ability of key market participants to operate in certain financial markets. Any of these factors could depress economic activity and restrict our access to capital, which could have a material adverse effect on our business, financial condition and results of operations and reduce the price of our equity shares. We operate manufacturing facilities internationally, including in the United Kingdom. Accordingly, the United Kingdom's withdrawal from the European Union may have an adverse impact on our international operations, particularly in the United Kingdom.
Our reputation, ability to do business, and results of operations may be impaired by legal compliance risks.
While we strive to maintain high standards, our internal controls and compliance systems may not always protect us from acts committed by our employees, agents, or business partners that would violate U.S. and/or non-U.S. laws or adequately protect our confidential information, including the laws governing payments to government officials, bribery, fraud, anti-kickback and false claims rules, competition, export and import compliance, money laundering, and data privacy laws, as well as the improper use of proprietary information or social media. Any such allegations, violations of law or improper actions could subject us to civil or criminal investigations in the U.S. and in other jurisdictions, could lead to substantial civil or criminal, monetary and non-monetary penalties, and related shareholder lawsuits, could lead to increased costs of compliance, could damage our reputation and could have a material effect on our financial statements.
If the Cequent spin-off does not qualify as a tax-free transaction, the Company and its shareholders could be subject to substantial tax liabilities.
The separation of our former Cequent businesses from TriMas in 2015 was conditioned on our receipt of an opinion from our tax advisors, in form and substance satisfactory to us, that the distribution of shares of our Cequent businesses in the spin-off qualifies as tax-free to the Cequent businesses, the Company and our shareholders for U.S. federal income tax purposes under Sections 355 and 368(a)(1)(D) and related provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), the Company and other members of our consolidated tax reporting group. The opinion relied on, among other things, various assumptions and representations as to factual matters made by the Company and the Cequent businesses which, if inaccurate or incomplete in any material respect, could jeopardize the conclusions reached by our advisor in its opinion. The opinion is not binding on the Internal Revenue Service (“IRS”), or the courts, and there is no assurance that the IRS or the courts will not challenge the qualification of the spin-off as a transaction under Sections 355 and 368(a) of the Code or that any such challenge would not prevail.


22

Table of Contents


If the spin-off were determined not to qualify under Section 355 of the Code, each U.S. holder of our common shares who received shares of the Cequent businesses in connection with the spin-off would generally be treated as having received a taxable distribution of property in an amount equal to the fair market value of the shares of the Cequent businesses that were received. That distribution would be taxable to each such shareholder as a dividend to the extent of our current and accumulated earnings and profits. For each such shareholder, any amount that exceeded our earnings and profits would be treated first as a non-taxable return of capital to the extent of such shareholder’s tax basis in his or her common shares of the Company with any remaining amount being taxed as a capital gain. We would be subject to tax as if we had sold common shares in a taxable sale for their fair market value and we would recognize taxable gain in an amount equal to the excess of the fair market value of such common shares over our tax basis in such common shares, which could have a material adverse impact on our financial condition, results of operations and cash flows.

Introduction
We areTriMas designs, develops and manufactures a diversified global manufacturer and providerdiverse set of products primarily for customers in the consumer products, aerospace & defense and industrial petrochemical, refinery,markets through its TriMas Packaging, TriMas Aerospace and oil and gas end markets.Specialty Products groups. Our wide range of innovative product solutionsproducts are engineereddesigned and designedengineered to solve application-specific challenges that our customers face. We believe our businesses share important and distinguishing characteristics, including: well-recognized and leading brand names in the focused markets we serve; innovative product technologies and features; a high-degree of customer approved processes and qualified products;qualifications; established distribution networks; relatively low ongoing capital investment requirements; strong cash flow conversion and long-term growth opportunities. While the majority of our revenue is in the United States, we manufacture and supply products globally to a wide range of companies. We are principally engagedreport our business activity in three reportable segments: Packaging, Aerospace and Specialty Products.
Key Factors and Risks Affecting Our Reported Results
Our businesses and results of operations depend upon general economic conditions. We serve customers in cyclical industries that are highly competitive, cyclical and are themselvesthat may be significantly impacted by changes in economic or geopolitical conditions.
There were six significant factors impactingIn March 2020, the President of the United States declared the coronavirus ("COVID-19") outbreak a national emergency, as the World Health Organization determined it was a pandemic. In response to the COVID-19 pandemic, federal, provincial, state, county and local governments and public health organizations or authorities around the world implemented a variety of measures intended to control the spread of the virus, including quarantines, "shelter-in-place" or "stay-at-home" and similar orders, travel restrictions, business curtailments and closures, social distancing, personal hygiene requirements, and other measures.
We have been, and continue to be, focused on making sure the working environments for our reported results in 2018 compared with 2017.
The first factor was an increase in sales levels across mostemployees are safe so our operations have the ability to deliver the products needed to support efforts to mitigate the COVID-19 pandemic. Nearly all of our end markets. manufacturing sites have been deemed essential operations and remained open during the COVID-19 pandemic, at varying levels of capacity and efficiency, experiencing only temporary shutdowns due to country-specific government mandates or for thorough cleaning as a result of suspected COVID-19 cases. The health of our employees, and the ability of our facilities to remain operational in the current regulated environment, will be critical to our future results of operations.
Our 2018divisions were impacted in 2020 at differing levels and times, beginning with our Asian facilities and strategic supply network, both primarily in China, in late January, followed by our European (primarily Italy) and North American facilities in February and March. We implemented new work rules and processes, which promote social distancing and increased hygiene to ensure the safety of our employees, particularly at our production facilities. These measures, while not easily quantifiable, have increased the level of manufacturing inefficiencies due to elevated levels of absenteeism, resulting in less efficient production scheduling and, in certain cases, short-term idling of production. We expect that we will continue to operate with these protocols in place for the foreseeable future.
Overall, 2021 net sales increased by 7.3%approximately $87.1 million, or 11.3%, compared with 2017, with increasesto 2020, primarily as a result of increased industrial demand in each of our three reportable segments. The sales increase was driven primarily by growth in our health, beauty and home care end market within our Packaging reportable segment, and higher sales levels of steel cylinder and oil and gas-related products within our Specialty Products reportablesegment, acquisitions in our Packaging segment and the impact of customers' stocking orders within our Aerospace segment. WeThese increases were partially offset by a decline in sales of our Packaging segment's dispensing and closure products that are used in applications to fight the spread of germs, which sales reached record-high levels in 2020 when there was a significant spike in demand following the onset of the COVID-19 pandemic, but now have abated to what we believe general industrial activity levels have beenis a new, and higher, normalized level.
The most significant drivers affecting our results of operations in 2018 versus 2017, particularly2021 compared with 2020, other than as directly impacted by demand level changes as a result of the COVID-19 pandemic, were goodwill and intangible asset impairment charges in 2020 in our Aerospace segment, our election to change our accounting policy for asbestos-related defense costs in 2020, realignment actions we undertook in response to reduced end-market demand following the outbreak of the COVID-19 pandemic, the impact of our recent acquisitions, increases in the United States,cost of certain raw materials, the refinancing of our long term debt in 2021 and we were well positioned to take advantagethe recognition of the incremental volume opportunities.benefit of certain tax planning strategies.
The second factor

During 2020, we determined there was continued positive momentum as we further leverageda triggering event requiring an interim quantitative impairment assessment for goodwill and indefinite-lived intangible assets within our Aerospace segment. While third quarter 2020 operating results were below pre-pandemic projected levels, the TriMas Business Model ("TBM"), which provideslarger driver of the triggering event was a significant reduction in the July 2020 financial projection update for a common platform to operatethe remainder of 2020 compared with prior projections, and manageuncertainty around the duration and magnitude of the impact of the COVID-19 pandemic on future financial results given the dependence of our multi-industry setAerospace segment reporting units on future levels of businesses. Usingair travel and new aircraft builds. We determined the TBM, we drive and leverage operating improvements through Kaizen and continuous improvement activities,carrying value of both of our Aerospace reporting units, as well as continuously evaluate, realignof certain trade names, exceeded the fair value, resulting in non-cash, pre-tax impairment charges of approximately $126.8 million to goodwill and streamline fixed$7.8 million to indefinite lived intangible assets.
During 2020, we elected to change our accounting policy for asbestos-related defense costs from accruing for probable and reasonably estimable defense costs associated with known claims expected to settle to accruing for all future defense costs for both known and unknown claims, which we now believe can be reasonably estimated. This accounting change has been reflected as a change in accounting estimate effected by a change in accounting principle. We recorded a non-cash, pre-tax charge in second quarter 2020 for asbestos-related costs of approximately $23.4 million, which is included in selling, general and administrative expenses. Operating underIn 2021, we commissioned our actuary to update the TBM contributed to increased operating profitasbestos study based on higher sales levels,data as we leveraged our fixed costs at a greater rate than in 2017.
The third factor affecting our year-over-year results was the enactment of the Tax Cuts and Jobs Act (the "Tax Reform Act") on December 22, 2017. We adopted the new legislation in the fourth quarter of 2017,September 30, 2021, and recorded one-time provisional chargesa non-cash, pre-tax charge of approximately $12.7 million related to taxing previously deferred foreign income and revaluing our net deferred tax assets. In 2018, we finalized these provisional charges, resulting in a tax benefit of approximately $0.4 million. The impact of these one-time charges resulting from adopting the Tax Reform Act, as well as the impact from the reduction in the U.S. Federal corporate tax rate from 35% to 21%, are the primary reasons for the decrease in our overall effective tax rate from 53.2% in 2017 to 21.4% in 2018.
The fourth factor impacting our 2018 results was an increase of approximately $7 million in material costs over 2017 levels, primarily related to oil and metal-based commodities. These increases primarily impacted our Packaging and Specialty Products reportable segments. Historically, we have been able to work with our suppliers to manage costs. Tactics we employ in mitigating commodity cost increases include commercial pricing adjustments, both contractual and negotiated, resourcing to alternate suppliers to secure better pricing or avoid import and transportation costs, and insourcing to better leverage our global manufacturing footprint. Certain of these measures take time, and in some cases some investment, to implement. We worked diligently on these efforts in 2018, and we believe we recovered or mitigated the majority of the cost increases. Historically, we have been generally able to mitigate the impact of increased commodity costs over time.

The fifth factor impacting our reported results was an adjustment in 2018 to terminate a legacy liability of approximately $8.2$1.5 million, which resultedis included in a reduction to corporate office selling, general and administrative expenses. Priorexpenses, to 2002,increase the liability estimate.
Beginning in second quarter 2020, we were wholly-owned by Metaldyne Corporationhave been executing certain realignment actions in response to reductions in current and expected future end market demand following the onset of the COVID-19 pandemic. We recorded pre-tax facility consolidation and employee separation costs of approximately $3.5 million and $6.2 million, respectively, in 2021. In 2020, we recorded a pre-tax charge of approximately $13.8 million related to inventory reductions, primarily as a result of a strategic decision in our Arrow Engine division to streamline its product line offering. We also recorded charges of approximately $2.3 million related to certain production equipment removed from service given reduced demand levels, and employee separation costs of approximately $3.8 million.
In December 2021, we completed the acquisition of Omega Plastics ("Metaldyne"Omega"). , which specializes in manufacturing custom components and devices for drug delivery, diagnostic and orthopedic medical applications, as well as components for industrial applications, for an aggregate amount of approximately $22.5 million, net of cash acquired. Omega, which is reported in the Company's Packaging segment, is located in Clinton Township, Michigan. Omega contributed approximately $0.7 million of net sales during 2021.
In connectionDecember 2021, we acquired TFI Aerospace ("TFI"), a manufacturer and supplier of specialty fasteners used in a variety of applications, predominately for the aerospace end market, for an aggregate amount of approximately $11.8 million, with the reorganization between TriMas and Metaldyne in June 2002, we assumed certain liabilities and obligations of Metaldyne, mainly comprised of contractual obligationsadditional contingent consideration ranging from zero to former TriMas employees, tax-related matters, benefit plan liabilities and reimbursements to Metaldyne of normal course paymentsapproximately $12.0 million to be madepaid based on TriMas' behalf. Metaldyne2023 and its U.S. subsidiaries filed voluntary petitions2024 earnings per the purchase agreement. TFI, which is reported in the Company's Aerospace segment, is located near Toronto, Canada. TFI contributed approximately $0.3 million of net sales during 2021.
In December 2020, we completed the acquisition of Affaba & Ferrari Srl ("Affaba & Ferrari"), which specializes in the design, development and manufacture of precision caps and closures for food & beverage and industrial product applications, for an aggregate amount of approximately $98.4 million, net of cash acquired. Affaba & Ferrari, which is reported in our Packaging segment, operates out of a highly automated manufacturing facility and support office located in Borgo San Giovanni, Italy. Affaba & Ferrari contributed approximately $36.3 million of incremental net sales during 2021.
In April 2020, we acquired the Rapak brand, including certain bag-in-box product lines and assets ("Rapak") for an aggregate amount of approximately $11.4 million. Rapak, which is reported in our Packaging segment, has two manufacturing locations in the United States Bankruptcy Court under Chapter 11States. Rapak contributed approximately $5.3 million of incremental net sales resulting from the January through March 2021 sales. Rapak has been performing below break-even operating profit as demand for its products, particularly those used in quick service restaurant applications, has significantly declined from pre-acquisition levels in 2019 due to the impact of the U.S. Bankruptcy CodeCOVID-19 pandemic.
In February 2020, we completed the acquisition of RSA Engineered Products ("RSA"), a provider of highly-engineered and proprietary components for air management systems used in 2009. critical flight applications, for an aggregate amount of approximately $83.7 million, net of cash acquired. RSA, located in Simi Valley, California, designs, engineers and manufactures highly-engineered components, including air ducting products, connectors and flexible joints, predominantly used in aerospace and defense engine bleed air, anti-icing and environmental control system applications. RSA contributed approximately $4.3 million of incremental net sales resulting from January and February 2021 sales.

In January 2018,first quarter 2021, we began experiencing an increase in material costs compared with 2020 levels, primarily for resin-based raw materials and components, as well as for certain types of steel. These material costs further increased throughout 2021. We have escalator/de-escalator clauses in our commercial contracts with certain of our customers, or can modify prices based on market conditions, and we have been taking actions to recover the U.S. Bankruptcy Court entered a final decreeincreased cost of raw materials. However, given the lag nature of the commercial pricing mechanisms, we have and will continue to close all remaining casesexperience net earnings pressure until resin costs begin to stabilize and/or decline for several consecutive months. We estimate that due to the lag in timing between incurring the cost increases and finalize the Metaldyne bankruptcy distribution trust, effectively terminating any potential obligationrecovering via commercial actions, our operating profit was negatively impacted by TriMas to Metaldyne.approximately $11 million in 2021, compared with 2020, primarily in our Packaging segment.
The sixth factor impacting our reported results was the refinancing ofIn 2021, we refinanced our long-term debt, in September 2017, whereby we issued $300issuing $400 million aggregate principal amount of 4.875%4.125% senior unsecured notes due October 2025April 15, 2029 ("2029 Senior Notes") at par value in a private placement offering. Proceedsunder Rule 144A of the Securities Act of 1933, as amended, and amending our existing credit agreement ("Credit Agreement"), extending the maturity to March 2026. We used the proceeds from the 2029 Senior Notes offering to pay fees and expenses of approximately $5.1 million related to the offering and approximately $1.1 million related to amending the Credit Agreement. The remaining cash proceeds from the 2029 Senior Notes were used to repayfor general corporate purposes, including repaying all outstanding obligationsrevolving credit facility borrowings and redeeming all of our formeroutstanding senior secured term loan A facilitynotes due 2020October 2025 ("Term Loan A Facility"2025 Senior Notes"), repaypaying cash for the entire $300.0 million outstanding principal amount plus $7.3 million as a portionredemption premium. The $5.1 million of outstanding obligations under our accounts receivable facility and pay fees and expenses related to the refinancing. In connection2029 Senior Notes were capitalized as debt issuance costs, while the $7.3 million redemption premium as well as approximately $3.0 million of unamortized debt issuance costs associated with the 2025 Senior Notes offering,were expensed in 2021.
In addition, our effective tax rate for 2021 was 17.1%, compared to 22.3% for 2020. We recorded income tax expense of approximately $11.9 million in 2021, as compared to an income tax benefit of $23.0 million in 2020. During 2021, we reported domestic and foreign pre-tax income of approximately $28.4 and $40.7 million, respectively, as compared to a 2020 domestic pre-tax loss of approximately $134.6 million and foreign pre-tax income of approximately $31.9 million. The rate for 2021 includes the impact of income tax incentives in a foreign jurisdiction, the impact of certain non-deductible expenses and an increase in the statutory tax rate in another foreign jurisdiction which increased the value of certain deferred tax assets. The effective tax rate for 2020 was impacted by a decrease in profitability in the U.S. resulting from various one-time charges, including impairment of goodwill and indefinite-lived intangible assets and a change in our accounting policy for asbestos-related defense costs. During 2020, we also amendedundertook certain tax-planning actions with respect to restructuring our existing credit agreement ("Credit Agreement") to increaseintercompany debt, resulting in the levelrecognition of permitted foreign currency borrowings, resize our revolving loan commitments and extend the maturity to September 2022. We believe the refinancing enhanced our capital structure, and also extended maturity dates and locked-in fixed rate debt at favorable long-term rates. We paid fees and expenses of approximately $10.8a $6.4 million in connection with refinancing-related activities, of which approximately $6.0 million was capitalized as deferred financing fees and $4.8 million was expensed, which was primarily related to the termination of interest rate swap agreements. In addition, we recorded non-cash charges of approximately $2.0 million related to the write-off of previously capitalized deferred financing fees.tax benefit.
Additional Key Risks that May Affect Our Reported Results
CriticalWe expect the COVID-19 pandemic will continue to impact us in the future at varying degrees. We expect the robust customer demand, compared with pre-pandemic demand levels, for our Packaging segment's dispensing pumps and closure products used in personal care and home care applications will continue, albeit with some reduction from the surge experienced in 2020 and early 2021, as we believe there is a positive secular trend focused on consumers' desire to stop the spread of germs and improve personal hygiene. Industrial demand in North America was lower in 2020 compared to previous levels, and while demand levels significantly increased in 2021, we are uncertain how and at what level demand will be impacted as governmental, travel or other restrictions are lifted, particularly in North America, where orders for our industrial cylinders, for example, are heavily influenced by the levels of construction and HVAC activity. We expect the aerospace market to continue to experience severe dislocation going forward, as except for the significant stocking orders for certain of our products received during 2021, our sales levels would be significantly lower than historical levels. With the current travel restrictions and sentiment, particularly low for international travel, aircraft manufacturers have slowed production, and since second quarter 2020 we have experienced a significant drop in aerospace-related sales related to new commercial airplane builds compared to prior levels. We expect, except as favorably impacted by the customers' stocking orders in 2021, lower levels of sales and related production to continue for the foreseeable future.
We have executed significant realignment actions since the onset of the COVID-19 pandemic, primarily in our Aerospace and Specialty Products segments, and also in certain Packaging product areas where demand has fallen, such as in the quick service and restaurant applications, to protect against the uncertain end market demand. We will continue to assess further actions if required. However, as a result of the COVID-19 pandemic's impact on global economic activity, and the continued potential impact to our future results of operations, as well if there is an impact to TriMas' market capitalization, we may record additional cash and non-cash charges related to incremental realignment actions, as well as for uncollectible customer account balances, excess inventory and idle production equipment.
Despite the potential decline in future demand levels and results of operations as a result of the COVID-19 pandemic, at present, we believe our capital structure is in a solid position. We have ample cash and available liquidity under our revolving credit facility to meet our debt service obligations, capital expenditure requirements and other short-term and long-term obligations for the foreseeable future.

The extent of the COVID-19 pandemic's effect on our operational and financial performance will depend in large part on future
developments, which cannot be predicted with confidence at this time. Future developments include the duration, scope and severity of the COVID-19 pandemic, the actions taken to contain or mitigate its impact, timing of widespread vaccine availability, and the resumption of normalized global economic activity. Due to the inherent uncertainty of the unprecedented and rapidly evolving situation, we are unable to predict with any confidence the likely impact of the COVID-19 pandemic on our future operations.
Beyond the unique risks presented by the COVID-19 pandemic, other critical factors affecting our ability to succeed include: our ability to create organic growth through product development, cross-selling and extending product-line offerings, and our ability to quickly and cost-effectively introduce and successfully launch new products; our ability to acquire and integrate companies or products that supplement existing product lines, add new distribution channels or customers, expand our geographic coverage or enable better absorption of overhead costs; our ability to manage our cost structure more efficiently via supply basechain management, internal sourcing and/or purchasing of materials, selective outsourcing and/or purchasing of support functions, working capital management, and greater leverage of our administrative functions.
Our overall business does not experience significant seasonal fluctuation, other than our fourth quarter, which has tended to be the lowest net sales quarter of the year due to holiday shutdowns at certain customers or other customers deferring capital spending to the following year. Given the short-cycle nature of most of our businesses, we do not consider sales order backlog to be a material factor. A growing amount of our sales is derived from international sources, which exposes us to certain risks, including currency risks.
We are sensitive to price movements inand availability of our raw materials supply base.supply. Our largest raw material purchases are for resins (such as polypropylene and polyethylene), steel, aluminum and other oil and metal-based purchased components. In addition to the factors affecting our 2021 results, there has been some volatility over the past two years as a direct and indirect result of foreign trade policy, where tariffs on certain of our commodity-based products sourced from Asia have been instituted, and certain North American suppliers have opportunistically increased their prices. We will continue to take actions to mitigate such increases, including implementing commercial pricing adjustments, resourcing to alternate suppliers and insourcing of previously sourced products to better leverage our global manufacturing footprint. Although we believe we are generally able to mitigate the impact of higher commodity costs over time, we may experience additional material costs and disruptions in supply in the future and may not be able to pass along higher costs to our customers in the form of price increases.increases or otherwise mitigate the impacts to our operating results.
Certain of our businesses in our Specialty Products reportable segment are sensitive to the demand for natural gas and crude oil in North America. For example, our Arrow Engine business is most directly impacted by these factors, as its engine, pump jack and compressor products are impacted by oil and gas rig counts and well completion activities. In addition, a portion of our Lamons business serves upstream customers at oil well sites that are impacted by fluctuating oil prices. The majority of this business provides parts for oil refineries and petrochemical plants, which may or may not decide to incur capital expenditures for their preventive maintenance or capacity expansion activities, both of which require use of our gaskets and bolts, in times of fluctuating oil prices. Separately, oil-based commodity costs are a significant driver of raw materials and purchased components used within our Packaging reportable segment. Although we have escalator/de-escalator clauses in commercial contracts with certain of our customers, or can modify prices based on market conditions to recover higher costs, our price increases generally lag the underlying material cost increase, and we cannot be assured of full cost recovery in the open market. If input costs increase at rapid rates, as they did during 2021, our ability to recover cost increases on a timely basis, much less at all, is made more difficult by the lag nature of these contracts.
Our Arrow Engine business in our Specialty Products segment is sensitive to the demand for natural gas and crude oil in North America. For example, demand for engine, pump jack and compressor products are impacted by active oil and gas rig counts and wellhead investment activities. Separately, oil-based commodity costs are a significant driver of raw materials and purchased components used within our Packaging segment.
Each year, as a core tenet of the TBM,TriMas Business Model, our businesses target cost savings from Kaizen and continuous improvement initiatives in an effort to lowerreduce, or otherwise offset, the impact of increased input and conversion costs or increasethrough increased throughput and yield rates, with a goal of at least covering inflationary and market cost increases. In addition, we continuously review our costsoperating cost structures to ensure alignment with current market demand.

Year Ended December 31, 20182021 Compared with Year Ended December 31, 20172020
The principal factors impacting us during the year ended December 31, 2018,2021, compared with the year ended December 31, 20172020 were:
increased sales levels across our end markets, primarily driven by higher demand for our industrialthe impact on global business activity of the COVID-19 pandemic;
approximately $134.6 million of goodwill and oil and gas-related products within our Specialty Products reportable segment and from growthindefinite-lived intangible asset impairment charges in 2020;
a change in our health, beauty and home care end market within our Packaging reportable segment;accounting policy for asbestos-related defense costs during 2020;
benefitsrealignment expenses in response to reduced end-market demand following the outbreak of leveraging the TBM, as we continue to drive operating improvements, as well as evaluate, realign and streamline fixed costs and selling, general and administrative expenses;COVID-19 pandemic;
the impact of the Tax Reform Act, contributing to a lower overall effective tax rate;our debt refinancing activities;
higher commodity costs, primarily related to oil and steel-based raw materials, primarily impacting our Packaging reportable segment;
the termination of the liability to Metaldyne, resulting in an approximate $8.2 million reduction in selling, general and administrative expenses; and
the impact of feesour recent acquisitions, primarily Affaba & Ferrari, in December 2020;
the impact of material cost increase, primarily resin-related; and expenses related
the impact of a reduction in our effective tax rate from 2020 to our issuance of Senior Notes and other refinancing activities in 2017.2021.
Overall, net sales increased approximately $59.4$87.1 million, or approximately 7.3%11.3%, to $877.1$857.1 million in 2018,2021, as compared to $817.7$770.0 million in 2017,2020, primarily as a result of acquisitions, which added approximately $46.9 million of sales. Organic sales, increased in all three reportable segments. Salesexcluding the impact of oilcurrency exchange and gas-related productsacquisitions, increased approximately $17.3$31.5 million, andprimarily due to increases in sales of products used in food and beverage applications in our Packaging segment and of industrial cylinder products increased approximately $16.2 million,in both within our Specialty Products reportable segment. Salesand Packaging segments. These increases were partially offset by the expected decline in sales of our health, beauty and home caredispensing products increased approximately $15.6 million withinthat help fight the spread of germs in our Packaging reportable segment.segment, as the demand levels decreased compared with the record-high levels in 2020. In addition, net sales increased by approximately $2.3$8.7 million due to net favorable currency exchange, as our reported results in U.S. dollars were favorably impacted as a result of the weakening U.S. dollar relative to foreign currencies.
Gross profit margin (gross profit as a percentage of sales) approximated 27.8%25.3% and 26.8%23.6% in 20182021 and 2017,2020, respectively. Gross profit margin increased primarily as a result of higher sales levels and lower facility exit costs, primarily within our Specialty Products and Packaging reportable segments. These increases were partially offset bydue the impact of higher commodity-related costs,lower realignment, contingent liability, and purchase accounting charges of approximately $13.0 million, $2.0 million, and $2.0 million, respectively, in 2021 than in 2020. These increases, plus a lessmore favorable product sales mix and pricing pressures, most notablyleveraging of our prior realignment actions in our health, beautySpecialty Products segment were partially offset by approximately $11 million higher material costs than recovered via commercial actions (primarily for resin) in our Packaging segment and home care end marketlower fixed cost absorption and labor inefficiencies within our Packaging reportableAerospace segment.
Operating profit (loss) margin (operating profit as a percentage of sales) approximated 13.9%11.1% and 10.9%(11.5)% in 20182021 and 2017,2020, respectively. Operating profit (loss) increased $32.9$183.4 million, to $122.1an operating profit of approximately $95.1 million in 2018,2021, as compared to $89.2an operating loss of approximately $88.3 million in 2017. Operating profit increased2020, primarily due to overallapproximately $134.6 million of goodwill and indefinite-lived intangible asset impairment charges as well as the impact of the $2.0 million pre-acquisition contingent liability charge within our Aerospace segment, which were recorded in 2020 and did not repeat in 2021. Operating profit and margin further increased due to higher sales levels and lower realignment and purchase accounting costs to exit, movein 2021 than in 2020. These increases were partially offset by higher material costs (primarily resin) in our Packaging segment and consolidate facilities in 2018 as compared to 2017. Operating profit also increased by approximately $8.2 million due to a reduction oflabor inefficiencies and lower fixed cost absorption within our recorded liability to Metaldyne following the U.S. Bankruptcy Court's final decree to close all remaining cases and terminate the Metaldyne bankruptcy distribution trust.Aerospace segment.
Interest expense decreased approximately $0.5$0.2 million, to $13.9$14.5 million in 2018,2021, as compared to $14.4$14.7 million in 2017,2020, as a lower weighted average borrowingseffective interest rate more than offset an increase in our interest rates.weighted average borrowings.
In 2017, weWe incurred approximately $10.5 million of debt financing and related expense in 2021, of which approximately $10.3 million was related to expenses incurred associated with the redemption of our 2025 Senior Notes and approximately $6.6$0.2 million related to coststhe write-off of previously capitalized deferred financing fees associated with the issuance of our Senior Notes, repayment of all outstanding obligations of our former Term Loan A Facility, termination of the interest rate swaps and the amendment of our Credit Agreement.

In finalizing these charges, we recorded an approximate $1.1 million income tax benefit related to revaluing our net deferred tax assets at the lower U.S. corporate tax rate, which was partially offset by an approximate $0.7 million income tax expense related to the deemed repatriation of undistributed non-U.S. subsidiary earnings. We also incurred tax charges of approximately $0.7 million directly attributable to increases in valuation allowances on certain deferred tax assets including foreign tax operating loss carryforwards. In 2017, we reported domestic and foreign pre-tax income of approximately $50.8 million and $15.5 million, respectively, and recognized$31.9 million.

We also incurred tax charges of approximately $0.5 million directly attributable to increases in valuation allowances on certain deferred tax assets. Our effective tax rate for 2020 was impacted by a decrease in profitability in the U.S. resulting from various one-time charges, including impairment of goodwill and indefinite-lived intangible assets including foreignand a change in our accounting policy for asbestos-related defense costs.

Acquisition-related sales growth was approximately $42.3 million, comprised of $36.3 million of sales from our health, beauty and home care products increased approximately $15.6December 2020 acquisition of Affaba & Ferrari, $5.3 million driven by higher sales in Asia and North America as well asresulting from the ramp up of new products. Sales of our industrial closures increased approximately $5.7 million andJanuary through March 2021 sales of our April 2020 acquisition of Rapak and $0.7 million of sales from our December 2021 acquisition of Omega. Sales of products used in food and beverage productsmarkets increased by approximately $0.6$19.1 million, bothprimarily due to increased demand for caps and closures and flexible packaging as the hospitality sector began to rebound from prior COVID-19 pandemic-related shutdowns. Sales of products used in industrial markets increased by approximately $13.5 million, primarily as a result of higher demand for closure products in North America. Additionally, netSales of dispensing products used in beauty and personal care as well as home care applications that help fight the spread of germs decreased by approximately $42.4 million, as demand has abated for these products from the peak levels in 2020 as a result of the COVID-19 pandemic. Net sales also increased by approximately $1.7$8.7 million due to favorable currency exchange, as our reported results in U.S. dollars were favorably impacted as a result of the weakening of the U.S. dollar relative to foreign currencies.
Packaging's gross profit increased approximately $3.0$3.3 million to $119.6$145.8 million, or 32.5%27.3% of sales, in 2018,2021, as compared to $116.6$142.4 million, or 33.8%29.2% of sales, in 2017,2020, primarily as a resultdue to the higher sales levels, as well asplus approximately $2.7$3.1 million of costs incurred in 2017 to consolidate manufacturing facilities in India and to finalize the move to a new facility in Mexico that did not recur. In addition, gross profit increased due to approximately $0.8 million of favorable currency exchange, as our reported results in U.S. dollars were favorably impacted as a result of the weakening of the U.S. dollar relative to foreign currencies. These increases were partially offset by approximately $3.5 million higher steel and resin-based material costs,Although gross profit dollars increased, gross profit margin decreased as well asthe impact of a lessmore favorable product sales mix, as higher margin industrial and pricing pressures, most notablyfood and beverage products comprised a larger percentage of total sales, was offset by approximately $11 million of higher material costs (primarily resin) than were recovered via sales price increases during 2021. Gross profit margin was also unfavorably impacted by inflationary headwinds on utilities costs, higher labor costs driven by pandemic-related shortages and higher freight costs driven by increased container costs and freight lane rates. In addition, we recognized approximately $1.6 million of realignment costs during 2021 primarily related to the closure of our Union City, California manufacturing facility and consolidation into our Indianapolis, Indiana and Woodridge, Illinois facilities as compared to $1.1 million of realignment costs in our health, beauty and home care end market.2020, primarily related to the disposal of certain equipment removed from service.

Year Ended December 31, 2017 Compared with Year Ended December 31, 2016
The principal factors impacting us during the year ended December 31, 2017 compared with the year ended December 31, 2016 were:
the impact of improved throughput and productivity in our Aerospace reportable segment, enabling this segment to achieve higher sales and profit levels in 2017;
the continued benefits of the realigned footprint within our Specialty Products reportable segment, with lower ongoing operating costs following several facility consolidations and closures;
the impact of Hurricane Harvey, primarily within our Specialty Products reportable segment;
the impact of fees and expenses related to our issuance of Senior Notes and other refinancing activities in 2017;
the impact of the Tax Reform Act, primarily impacting our 2017 income tax expense; and
approximately $98.9 million goodwill and intangible asset impairment charges in 2016 in our Aerospace reportable segment.
Overall, net sales increased approximately $23.7 million, or approximately 3.0%, to $817.7 million in 2017, as compared to $794.0 million in 2016, as sales increased in all three reportable segments. Sales within our Aerospace reportable segment increased approximately $9.4 million, primarily as a result of improved manufacturing throughput to meet customer demand levels. Sales in our Specialty Products reportable segment increased approximately $10.8 million, excluding the impact of currency exchange, due to increased U.S. industrial and oilfield activity and higher sales in North America resulting from improved delivery performance, partially offset by lower sales in Europe as a result of the closure of our Wolverhampton, United Kingdom facility. Sales within our Packaging reportable segment increased by approximately $5.0 million, excluding the impact of currency exchange, primarily due to increased demand for our industrial closures and food and beverage products in North America. These increases were partially offset by approximately $1.4 million of net unfavorable currency exchange, primarily in our Packaging reportable segment, as our reported results in U.S. dollars were negatively impacted as a result of the stronger U.S. dollar relative to foreign currencies.
Gross profit margin (gross profit as a percentage of sales) approximated 26.8% and 26.5% in 2017 and 2016, respectively. Gross profit margin increased primarily due to improved manufacturing efficiency levels and reduced manufacturing spend, primarily within our Aerospace reportable segment, and as a result of the footprint realignment actions within our Specialty Products reportable segment. This increase was partially offset by costs associated with the closure and consolidation of manufacturing facilities in India and Mexico within our Packaging reportable segment, and the Mexico facility within our Specialty Products reportable segment. In addition, gross profit was impacted by approximately $0.8 million of unfavorable currency exchange, as our reported results in U.S. dollars were negatively impacted as a result of the stronger U.S. dollar relative to foreign currencies.
Operating profit (loss) margin (operating profit (loss) as a percentage of sales) approximated 10.9% and (5.3)% in 2017 and 2016, respectively. Operating profit increased approximately $131.1 million, to $89.2 million in 2017, as compared to an operating loss of $41.9 million in 2016, Operating profit and margin increased primarily due to approximately $98.9 million in goodwill and intangible asset impairment charges in our Aerospace reportable segment in 2016 that did not repeat in 2017. Operating profit and margin also increased as a result of higher sales levels across all reportable segments and productivity initiatives to improve scheduling and throughput, particularly in our Aerospace reportable segment, and the impact of our footprint realignment activities within our Specialty Products reportable segment. These factors were partially offset by the costs incurred in 2017 associated with footprint consolidation and relocation projects within our Packaging and Specialty Products reportable segments.
Interest expense increased approximately $0.7 million, to $14.4 million in 2017, as compared to $13.7 million in 2016. The increase in interest expense was primarily due to an increase in our interest rates, which more than offset lower average borrowings. Our weighted average borrowings decreased to approximately $381.8 million in 2017, from approximately $454.1 million in 2016. The effective weighted average interest rate on our outstanding variable rate borrowings, including our Credit Agreement and accounts receivable facilities, increased to approximately 2.8% for 2017, from approximately and 2.2% for 2016. In addition, in September 2017, we repaid our former Term Loan A facility with proceeds from the Senior Notes, which bear interest at 4.875%.
We incurred debt financing and related expenses of approximately $6.6 million in 2017 related to costs associated with the issuance of our Senior Notes, repayment of all outstanding obligations of the Term Loan A Facility, termination of the interest rate swaps and the amendment of our existing credit agreement.
Other expense, net decreased approximately $0.7 million to $1.9 million in 2017, from $2.6 million in 2016. The decrease was primarily due to one-time settlement and curtailment charges of approximately $1.3 million for defined benefit pension plans in 2016 that did not recur, partially offset by an increase in losses on transactions denominated in foreign currencies.

Income tax expense increased approximately $53.7 million, to $35.3 million of tax expense in 2017, as compared to $18.4 million of tax benefit in 2016. The effective income tax rate for 2017 was 53.2%, compared to 31.7% for 2016. During 2017, we reported domestic and foreign pre-tax income of approximately $50.8 million and $15.5 million, respectively, and recognized tax benefits of approximately $2.0 million due to a change in an uncertain tax position for which the statute of limitations expired and research and manufacturing tax incentives. We also recognized approximately $12.7 million of income tax expense as a result of the Tax Reform Act, including $3.7 million of provisional expense related to revaluing our net deferred tax assets at the lower U.S. corporate tax rate, and $9.0 million of provisional tax expense related to the deemed repatriation of approximately $110.0 million of undistributed non-U.S. subsidiary earnings. We also incurred tax charges of approximately $0.5 million directly attributable to increases in valuation allowances on certain deferred tax assets including foreign tax operating loss carryforwards. In 2016, we reported domestic pre-tax losses of approximately $69.9 million and foreign pre-tax income of approximately $11.6 million, and recognized tax benefits of approximately $2.2 million due to a change in an uncertain tax position for which the statute of limitations expired and research and manufacturing tax incentives.  In addition, we were unable to record tax benefit of approximately $5.1 million related to pre-tax goodwill impairment charges in the U.S. We also incurred tax charges of approximately $2.1 million directly attributable to increases in valuation allowances on certain deferred tax assets including foreign tax operating loss carryforwards.
Net income (loss) increased approximately $70.8 million, to income of $31.0 million in 2017, from a loss of $39.8 million in 2016. The increase was primarily the result of an approximately $131.1 million increase in operating profit and decreases in other expenses, net of approximately $0.7 million, partially offset by an increase in income tax expense of approximately $53.7 million, an increase in debt financing and related expenses of approximately $6.6 million in connection with the refinancing of our our long-term debt and an increase in interest expense of approximately $0.7 million.
See below for a discussion of operating results by reportable segment.
Packaging.   Net sales increased approximately $3.3 million, or 0.9%, to $344.6 million in 2017, as compared to $341.3 million in 2016. Sales of our industrial closures increased approximately $2.7 million due to higher demand in North America and Europe. Sales of our food and beverage products increased approximately $2.3 million due to increased demand in North America. Additionally, sales of our health, beauty and home care products were flat year-over-year, as higher demand in Asia and Europe was offset by lower demand in North America. The sales increase was partially offset by approximately $1.7 million of unfavorable currency exchange, as our reported results in U.S. dollars were negatively impacted as a result of the stronger U.S. dollar relative to foreign currencies.
Packaging's gross profit decreased approximately $4.4 million to $116.6 million, or 33.8% of sales, in 2017, as compared to $121.0 million, or 35.5% of sales, in 2016. While sales increased, gross profit dollars and margin decreased, primarily as a result of costs associated with facility moves. During 2017, we ramped up production in our new manufacturing facility in Mexico, incurring approximately $1.9 million higher costs than in the former, and now closed Mexican facility in 2016, as costs related to the capacity expansion plus inefficiencies and start-up costs more than offset initial move costs incurred in 2016. In addition, we incurred approximately $1.1 million of costs in 2017 to consolidate manufacturing facilities in India. Gross profit also declined due to an unfavorable product sales mix in North America and by approximately $0.9 million due to unfavorable currency exchange, as our reported results in U.S. dollars were negatively impacted as a result of the stronger U.S. dollar relative to foreign currencies.
Packaging's selling, general and administrative expenses decreased approximately $3.7 million to $38.3 million, or 11.1% of sales, in 2017, as compared to $42.0 million, or 12.3% of sales, in 2016. The decrease was primarily due to higher costs incurred in 2016 in connection with re-organizing our go-to-market strategy based on global product categories, as well as generally lower go-forward spending levels resulting from this reorganization. Additionally, we recognized approximately $1.0 million of severance and other costs related to the move of our Mexican facilities during 2016, and recorded an approximate $1.0 million charge in 2017 to reserve an outstanding accounts receivable amount for a European customer who filed for bankruptcy.
Packaging's operating profit increased approximately $2.0 million to $80.6 million, or 23.4% of sales, in 2017, as compared to $78.6 million, or 23.0% of sales, in 2016. Operating profit increased primarily due to lower ongoing selling, general and administrative expenses associated with our re-organization efforts as well as an approximate $2.5 million gain on the sale of the former Mexico facility. These impacts were partially offset by the charge recorded in 2017 to reserve an outstanding accounts receivable amount, costs associated with our India facility consolidation and new facility in Mexico and approximately $0.6 million of unfavorable currency exchange.
Aerospace.    Net sales increased approximately $9.4 million, or 5.4%, to $184.3 million in 2017, as compared to $174.9 million in 2016. We continued to improve production scheduling and manufacturing efficiencies, which enabled us to increase daily production rates and ship higher levels of net sales in 2017 as compared to 2016. Sales to our distribution customers increased approximately $7.0 million, as order patterns from our customers continued to stabilize and increase in 2017 as compared to the lower and more volatile levels throughout 2016. Sales to our OE customers increased approximately $2.4 million.

Gross profit within Aerospace increased approximately $13.2 million to $48.9 million, or 26.5% of sales, in 2017, from $35.7 million, or 20.4% of sales, in 2016, primarily as a result of higher sales levels. Further, in 2016, we incurred additional costs and experienced lower fixed cost absorption associated with production scheduling and manufacturing inefficiencies, primarily in our Commerce, California facility. We have improved the efficiency levels during 2017 and reduced manufacturing spend levels despite higher demand level in this facility.
Selling, general and administrative expenses decreased approximately $4.8 million to $22.4 million, or 12.1% of sales, in 2017, as compared to $27.2 million, or 15.5% of sales, in 2016, primarily due to approximately $2.0 million of lower estimated uncollectable accounts receivable expenses as a result of collection of previously reserved customer balances and approximately $2.8 million of reduced professional fees and certain administrative support costs.
Operating profit (loss) within Aerospace increased approximately $116.9 million to an operating profit of $26.4 million, or 14.3% of sales, in 2017, as compared to an operating loss of $90.5 million, or 51.8% of sales, in 2016. Operating profit and related margin increased primarily due to approximately $98.9 million in goodwill and intangible asset impairment charges in 2016 that did not repeat in 2017. Operating profit also increased as a result of higher sales levels, improved production scheduling and manufacturing efficiencies and lower selling, general and administrative expenses.
Specialty Products.    Net sales for 2017increased approximately $11.1 million, or 4.0%, to $288.9 million, as compared to $277.8 million in 2016. Sales of our oil and gas related products increased by approximately $11.3 million due to increased customer demand following improvements in our on-time delivery, increasing our share of turnaround activity and increases in drilling activity in the United States and Canada and the continued stabilization of oil prices. Sales of our industrial cylinders increased by approximately $4.1 million, primarily due to increased U.S. industrial activity and enhanced responsiveness to support shorter customer order lead-times. These increases were partially offset by a decrease in net sales of oil and gas related products of approximately $4.3 million in Europe, primarily due to exiting our facility in the United Kingdom.
Gross profit within Specialty Products decreased approximately $0.2 million to $53.9 million, or 18.6% of sales, in 2017, as compared to $54.1 million, or 19.5% of sales, in 2016. While gross profit increased as a result of higher sales levels and improved leverage resulting from our lower fixed cost structure, these impacts were essentially offset by $1.6 million higher facility closure costs in 2017 than in 2016, primarily related to costs incurred in 2017 to close our Mexico facility and costs incurred in 2016 to close our United Kingdom facility, and higher costs, inefficiencies and a less favorable oil and gas product sales mix as a result of Hurricane Harvey in 2017.
Selling, general and administrative expenses within Specialty Products decreased approximately $13.0 million to $36.9 million, or 12.8% of sales, in 2017, as compared to $49.9 million, or 17.9% of sales, in 2016. Selling, general and administrative expenses decreased by approximately $7.2 million as a result of elimination of costs related to closed facilities and by approximately $1.0 million as a result of an increase in reserves for past due accounts receivable in 2016 that did not repeat in 2017. The remaining $4.8 million decrease was primarily due to lowering our ongoing operating costs associated with the Company's current operating footprint following completion of significant realignment activities.
Operating profit within Specialty Products increased approximately $9.4 million to $12.3 million, or 4.3% of sales, in 2017, as compared to $2.9 million, or 1.0% of sales, in 2016, primarily as a result of lower selling, general and administrative expenses related to prior footprint realignment activities, partially offset by a pre-tax charge of approximately $3.5 million recorded within net loss on disposition of assets related to our 2017 exit of our Wolverhampton, United Kingdom facility.

Cash Flows
Cash flows provided by operating activities of continuing operations in 20182021 were approximately $129.3$134.2 million, as compared to $120.1approximately $127.4 million in 2017.2020. Significant changes in cash flows provided by operating activities of continuing operations and the reasons for such changes are as follows:
In 2018,2021, the Company generated $146.0approximately $139.2 million in cash flows, based on the reported net income of $83.3approximately $57.3 million and after considering the effects of non-cash items related to lossesdepreciation, amortization, loss on dispositions of businesses and other assets, depreciation, amortization, changes in deferred income taxes, debt financing and related expenses, stock-based compensation, change in legacy liability estimate, and other operating activities. In 2017,2020, the Company generated $111.2approximately $105.0 million in cash flows based on the reported net incomeloss of $31.0approximately $79.8 million and after considering the effects of similar non-cash items.items and the impairment of goodwill and indefinite-lived intangible assets.
Increases in accounts receivable resulted in a use of cash of approximately $11.4$11.2 million in 2018, primarily due to the increase in sales levels and the timing of sales and collection of cash. Decreases2021, while decreases in accounts receivable resulted in a source of cash of approximately $1.2$9.6 million in 2017.2020, primarily due to timing of net sales and related cash collections. Days sales outstanding of receivables remained flat year-over-year.relatively consistent in 2021 compared to 2020, and decreased by approximately four days through 2020 compared to 2019, as we placed a significant focus on our credit and collections process, particularly in those businesses most impacted by the pandemic where credit risk was heightened.

In considering the economic uncertainty surrounding the potential business impacts from the COVID-19 pandemic with respect to our operations, supply chains, distribution channels, and end-market customers, we took certain defensive actions during 2020 as we monitored our cash position and available liquidity. These actions included suspending our repurchase of our common stock, borrowing on our revolving credit facility, tightening our capital expenditures, advanced monitoring of our accounts receivable balances and flexing cost structures of operations expected to be most impacted by COVID-19. Given strong cash generation and our current liquidity position, we subsequently relaxed certain of these actions, choosing to further invest in capital expenditures, resume purchasing shares of our common stock and initiating a cash dividend.
The majority of our cash on hand as of December 31, 2018 is recorded as a Corporate asset and2021 is located within the United States. We have aggregateStates, and given available funding under our revolving credit and accounts receivable facilitiesfacility of $284.9$300.0 million at December 31, 2018 after2021 (after consideration of the aforementioned leverage restrictions. Basedrestrictions) and based on forecasted cash sources and requirements inherent in our business plans, we believe that our liquidity and capital resources, including anticipated cash flows from operations, will be sufficient to meet our debt service, capital expenditure and other short-term and long-term obligation needs for the foreseeable future.future, as well as dividends and share repurchases.
We are subject to variable interest rates on our revolving credit facility. At December 31, 2018,2021, 1-Month LIBOR approximated 2.50%0.10%. At December 31, 2018,2021, we had no amounts outstanding on our revolving credit facility and, therefore, no variable rate-based borrowings outstanding.
In November 2021, we amended the Credit Agreement to replace LIBOR with a benchmark interest rate determined based on the currency denomination of borrowings, effective January 1, 2022.
In addition to our long-term debt, we have other cash commitments related to leases. We account for these lease transactions primarily as operating leases, and incurred rent expense fromfor continuing operations related thereto of approximately $12.3$11.0 million in 2018.2021. We continue to be party to non-cancelable leases for certain facilities we have exited as part of restructuring activities, and have entered into sublease agreements to minimize our net lease payments. We expect leasing will continue to be an available financing option to fund future capital expenditure requirements.
We continuously evaluate strategies to redeploy our cash, including returning capital to our shareholders. In November 2015,March 2020, we announced our Board of Directors had authorized us to increase the purchase of our common stock up to $50$250 million in the aggregate, an increase of $100 million from the previous authorization. During 2021, 2020 and 2019, we purchased 596,084, 1,582,049 and 1,230,050 shares of our outstanding common stock.  During 2018,stock for approximately $19.1 million, $39.4 million and $36.7 million, respectively. Since the initial authorization through December 31, 2021, we have purchased 442,6323,850,815 shares of our outstanding common stock for an aggregate purchase price of approximately $12.1$107.4 million. We will continue to evaluate opportunities to return capital to shareholders through the purchase of our common stock, depending on market conditions, including the potential impact of the COVID-19 pandemic, and other factors.

2018 was a strong operationalOver the past two years, the COVID-19 pandemic has significantly affected each of our businesses and financial yearhow we operate, albeit in different ways and magnitudes. Sales in our Packaging segment for TriMas, markingdispensing and closure products we supply that are used in applications to fight the spread of germs have continued to be much stronger than before the COVID-19 pandemic, although, as expected, have abated from peak levels in 2020 at the onset of the COVID-19 pandemic. Sales in our second full yearSpecialty Products segment had been depressed by low levels of successfully operating underindustrial activity in the TriMas Business Model, which provides a standardized setU.S. during 2020, but have since strongly rebounded in the last nine months of processes that we follow2021. Sales in our Aerospace segment are expected to drive results across our multi-industry set of businesses. We experienced year-over-year increases in sales, and leveraged those increases into higher operating profit and related margin, with further improvement in net incomebe lower than historical levels for an indefinite period as a result of low new commercial aircraft builds, but have been significantly boosted by customers' stocking orders throughout 2021.
We believe our 2021 financial results demonstrate our ability to effectively leverage our TriMas Business Model, working across our businesses with a high degree of connectivity to respond to changing market conditions, including the ongoing challenges presented by the COVID-19 pandemic. We have capitalized on opportunities where market demand was high, while also taking swift actions where market demand was sharply reduced. We have continued to take proactive realignment actions to mitigate the effects of lower tax rate followingdemand from the enactmentCOVID-19 pandemic as much as practical, while at the same time growing our businesses through organic new products as well as via bolt-on acquisitions.
Looking forward, we believe there will be a continued period of the Tax Reform Act. We also generated significant cash flow in 2018, strengtheninguncertainty related to demand levels for our balance sheetproducts, whether it be when production rates for future capital deployment while affording us the opportunitynew aircraft builds, which require our fasteners and engineered products, will ramp-up, or whether general industrial activity will continue to buy back more than $12 million of our common stock.
increase toward pre-pandemic levels. We expect to continue our positive momentumto mitigate, as much as practical, the impact of low volumes in 2019,the most challenged end markets, executing realignment actions as necessary so we are positioned to gain operating leverage when these end markets recover. We believe we areremain well positioned to capitalize on growth opportunities,the recovery of the aerospace market, just as we have with the improvement in the industrial markets in the back half of 2021, as well as have instilled a culture of Kaizen and continuous improvement to generate additional efficiencies, cost savings and leveragecapture available market growth opportunities. We believe the continued effectiveness of vaccines, as well as continued measures intended to control the spread of the virus and future variants thereof, are among the most significant factors that could impact demand for our products.

As a result of continued uncertainties resulting from the COVID-19 pandemic, and their potential impact to our future results of operations, as well as to TriMas' market capitalization, we may record additional cash and non-cash charges related to further realignment actions, as well for uncollectible customer account balances, excess inventory and idle production equipment.

We will continueexpect to prioritize growth programs, particularly in our Packaging and Aerospace reportable segments, where we have many initiatives underway that we expect will benefit us in 2019.  We will also continue to ensure our cost structures remain aligned with customer demand in the end markets we serve, most notably in our Specialty Products reportable segment. We will continue to leverage the tenets of theour TriMas Business Model to manage our multi-industry businesses and address the ongoing challenges presented by the COVID-19 pandemic, and on a longer-term basis, achieve our growth plans, execute continuous improvement initiatives to offset inflationary pressures, and seek lower-cost sources for input costs, all while continuously assessing the appropriateness of our manufacturing footprint productivity and fixed-cost structure.
Impact of New Accounting Standards
See Note 2,, "New Accounting Pronouncements," included in Item 8, "Financial Statements and Supplementary Data," within this Form 10-K.
Critical Accounting Policies
The following discussion of accounting policies is intended to supplement the accounting policies presented in Note 3,, "Summary of Significant Accounting Policies" included in Item 8, "Financial Statements and Supplementary Data," within this Form 10-K. Certain of our accounting policies require the application of significant judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, our evaluation of business and macroeconomic trends, and information from other outside sources, as appropriate.
Receivables.    Receivables are presented net of allowances for doubtful accounts of approximately $3.4$1.6 million and $4.1$2.1 million at December 31, 20182021 and 2017,2020, respectively. We monitor our exposure for credit losses and maintain adequate allowances for doubtful accounts. We determine these allowances based on our historical write-off experience and/or specific customer circumstances and provide such allowances when amounts are reasonably estimable and it is probable a loss has been incurred. WeAlthough we have been growing business with certain of our larger customers, and there has been some industry consolidation where certain of our customers are merging, we do not believe that significant credit risk exists or that we have concentrationsa significant concentration of accounts receivable with a single customer or group of customers and do not believe that significant credit risk exists due to our diverse customer base. See Item 1A, "Risk Factors," for additional information regarding risks associated with a concentrated customer base. Prior to March 2018, when we terminated this facility, trade accounts receivable of substantially all domestic business operations may have been sold, on an ongoing basis, to a wholly-owned, special purpose entity, but remained included in our consolidated balance sheet.
Depreciation and Amortization.    Depreciation is computed principally using the straight-line method over the estimated useful lives of the assets. Annual depreciation rates are as follows: building and land/building improvements three to 40 years, and machinery and equipment, three to 15 years. Capitalized debt issuance costs are amortized over the underlying terms of the related debt securities. Customer relationship intangibles are amortized over periods ranging from five to 25 years, while technology and other intangibles are amortized over periods ranging from one to 30 years.
Impairment of Long-Lived Assets and Definite-Lived Intangible Assets.    We review, on at least a quarterly basis, the financial performance of each business unit for indicators of impairment. In reviewing for impairment indicators, we also consider events or changes in circumstances such as business prospects, customer retention, market trends, potential product obsolescence, competitive activities and other economic factors. An impairment loss is recognized when the carrying value of an asset group exceeds the future net undiscounted cash flows expected to be generated by that asset group. The impairment loss recognized is the amount by which the carrying value of the asset group exceeds its fair value.

Goodwill and Indefinite-Lived Intangibles.    We assess goodwill and indefinite-lived intangible assets for impairment at the reporting unit level on an annual basis as of October 1, by reviewing relevant qualitative and quantitative factors. More frequent evaluations may be required if we experience changes in our business climate or as a result of other triggering events that take place. IfAn impairment loss is recognized when the carrying value of the asset exceeds its fair value, a possible impairment exists and further evaluation is performed.value.
We determine our reporting units at the individual operating segment level, or one level below, when there is discrete financial information available that is regularly reviewed by segment management for evaluating operating results. For purposes of our 20182021 goodwill impairment test, we had five reporting units, three of which had goodwill, within our three reportable segments.

Table of Contents

We first perform a qualitative assessment for our annual goodwill impairment test and for our indefinite-lived intangible asset impairment test, which involves significant use of management's judgment and assumptions to determine whether it is more likely than not that the fair value of a reporting unit or indefinite-lived intangible asset is less than its carrying amount. In conducting the qualitative assessment, we consider macroeconomic conditions, industry and market considerations, overall financial performance, entity and reporting unit specific events, capital markets pricing, recent fair value estimates and carrying amounts, as well as legal, regulatory, and contractual factors. These factors are all considered in reaching a conclusion about whether it is more likely than not that the fair values of the intangible assets are less than the carrying values. If we conclude that further testing is required, we would perform a quantitative valuation to estimate the fair value of our intangible assets.
For purposes of the 20182021 annual impairment tests, based on the qualitative assessments, we determined there were no indications that the fair value of a reporting unit or indefinite-lived intangible asset was less than its carrying amount; therefore, we determined that quantitative assessments were not required.
Future declines in sales and/or operating profit, declines in our stock price, or other changes in our business or the markets for our products could result in further impairments of our goodwill and indefinite-lived intangible assets.
Pension Benefits.    We engage independent actuaries to compute the amounts of liabilities and expenses under defined benefit pension plans, subject to the assumptions that we determine are appropriate based on historical trends, current market rates and future projections as of the measurement date. Annually, we review the actual experience compared to the most significant assumptions used and makes adjustments to the assumptions, if warranted. Discount rates are based upon an expected benefit payments duration analysis and the equivalent average yield rate for high-quality fixed-income investments. Pension benefits are funded through deposits with trustees and the expected long-term rate of return on plan assets is based upon actual historical returns modified for known changes in the market and any expected change in investment policy. Certain accounting guidance, including the guidance applicable to pensions, does not require immediate recognition of the effects of a deviation between actual and assumed experience or the revision of an estimate. This approach allows the favorable and unfavorable effects that fall within an acceptable range to be netted.
Income Taxes.    We compute income taxes using the asset and liability method, whereby deferred income taxes using current enacted tax rates are provided for the temporary differences between the financial reporting basis and the tax basis of assets and liabilities and for operating loss and tax credit carryforwards. We determine valuation allowances based on an assessment of positive and negative evidence on a jurisdiction-by-jurisdiction basis and record a valuation allowance to reduce deferred tax assets to the amount more likely than not to be realized. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We record interest and penalties related to unrecognized tax benefits in income tax expense.
On December 22, 2017,Asbestos-related Matters. We accrue loss reserves for asbestos-related matters based upon an estimate of the Tax Reform Act was signed into law. Amongultimate liability for claims incurred, whether reported or not, including an estimate of future settlement costs and costs to defend. We utilize known facts and historical trends for Company-specific and general market asbestos-related activity, as well as an actuarial valuation in determining estimated required reserves which we believe are probable and reasonably estimable. Asbestos-related accruals are assessed at each balance sheet date to determine if the provisions, the Tax Reform Act reduces the Federal statutory corporate income tax rate from 35% to 21% effective January 1, 2018, implements a territorial tax system and imposes a one-time tax on the deemed repatriation of undistributed earnings of non-U.S. subsidiaries, introduces additional limitations on the deductibility of interest, allowsliability remains reasonably stated. Accruals for the immediate expensing of capital expenditures through 2023 and modifies or repeals many business deductions and credits. 
While the Tax Reform Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. Authoritative guidance has been published that allows companies to make an accounting policy election to either account for deferred taxes related to GILTI inclusions or treat any taxes on GILTI inclusions as period costs. We have elected to account for GILTI taxasbestos-related matters are included in the periodconsolidated balance sheet in which it is incurred,“Accrued liabilities” and therefore have not provided any deferred tax impacts on GILTI in our consolidated financial statements for the years ended December 31, 2018 and 2017.“Other long-term liabilities.”

Table of Contents


The BEAT provisions in the Tax Reform Act eliminate the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. We do not expect the BEAT provisions to have a significant impact to our consolidated financial statements, and have not included any tax impacts of BEAT in our consolidated financial statements for the years ended December 31, 2018 and 2017.
Other Loss Reserves.    We have other loss exposures related to insurance, litigation and environmental claims, asbestos claims and litigation.claims. Establishing loss reserves for these matters requires the use of estimates and judgment in regard to risk exposure and ultimate liability. We are generally self-insuredparty to high deductible insurance programs for losses and liabilities related principally to workers' compensation, health and welfare claims and comprehensive general, product and vehicle liability. Generally, we are responsible for up to $0.8$0.8 million per occurrence under our retention program for workers' compensation, between $0.3up to $1.5 million and $1.5 million per occurrence under our retention programs for comprehensive general, product and vehicle liability, and have a $0.3$0.4 million per occurrence stop-loss limit with respect to our self-insured group medical plan. We accrue loss reserves up to our retention amounts based upon our estimates of the ultimate liability for claims incurred, including an estimate of related litigation defense costs, and an estimate of claims incurred but not reported using actuarial assumptions about future events. We accrue for such items when such amounts are reasonably estimable and probable. We utilize known facts and historical trends, as well as actuarial valuations in determining estimated required reserves. Changes in assumptions for factors such as medical costs and actual experience could cause these estimates to change significantly.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk
In the normal course of business, we are exposed to market risk associated with fluctuations in commodity prices, insurable risks due to property damage, employee and liability claims, and other uncertainties in the financial and credit markets, which may impact demand for our products.
We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies. The functional currencies of our foreign subsidiaries are primarily the local currency in the country of domicile. We manage these operating activities at the local level and revenues and costs are generally denominated in local currencies; however, results of operations and assets and liabilities reported in U.S. dollars will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar. We may use derivative financial instruments to manage currency risks associated with our procurement activities denominated in currencies other than the functional currency of our subsidiaries and the impact of currency rate volatility on our earnings.
We aremay also be subject to interest risk as it relates to long-term debt, for which we have historically and may prospectively employ derivative instruments such as interest rate swaps to mitigate the risk of variable interest rates. See Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" for details about our primary market risks, and the objectives and strategies used to manage these risks. Also see Note 10,13, "Long-term Debt," and Note 11,14, "Derivative Instruments," included in Item 8, "Financial Statements and Supplementary Data," within this Form 10-K for additional information.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of TriMas Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of TriMas Corporation and subsidiaries (the "Company") as of December 31, 20182021 and 2017,2020, the related consolidated statements of operations, comprehensive income, cash flows, and shareholders’ equity, for each of the three years in the period ended December 31, 2018,2021, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20182021 and 2017,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018,2021, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 2019,March 01, 2022, expressed an unqualified opinion on the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) related to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.
Goodwill - Aerospace Fasteners Reporting Unit - Refer to Notes 3 and 9 to the financial statements.
Critical Audit Matter Description
The Company assesses goodwill for impairment on an annual basis as of October 1, and more frequently if there are changes in the business climate or as a result of a triggering event taking place. The Company’s evaluation of goodwill impairment involves a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The qualitative assessment involves significant use of management’s judgment and assumptions related to macroeconomic conditions, industry and market considerations, overall financial performance, entity and reporting unit specific events, and capital markets pricing. The Company also considered recent valuations of its reporting units, including the difference between the most recent fair value estimate and the carrying amount. Changes in these assumptions could have a significant effect on management’s conclusion about whether a quantitative goodwill impairment test is necessary to estimate the fair value of its reporting units.
45

Table of Contents

The Company’s goodwill balance was $315 million as of December 31, 2021, of which $70 million was allocated to the Aerospace Fasteners Reporting Unit (“Aerospace Fasteners”). The Company concluded there were no indications that the fair value of any reporting unit was less than the carrying amount, therefore a quantitative assessment was not performed, and no impairment was recognized.
Given the nature of the Aerospace Fasteners operations, the assumptions used in the qualitative assessment, and the difference between the most recent fair value estimate and the carrying amount of Aerospace Fasteners, auditing management’s judgments related to the impact of macroeconomic conditions, overall financial performance for Aerospace Fasteners, and capital markets pricing involved especially subjective judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to management’s qualitative evaluation of goodwill impairment for Aerospace Fasteners included the following, among others:
We tested the effectiveness of controls over goodwill, including those over management's judgments and assumptions related to macroeconomic conditions, industry and market considerations, overall financial performance, entity and reporting unit specific events, capital markets pricing, recent fair value estimates and carrying amounts.
We evaluated management's ability to accurately forecast future revenues and EBITDA margins by comparing actual results to management's historical forecasts.
We evaluated the reasonableness of management’s qualitative assessment of factors affecting revenue and EBITDA margin forecasts by comparing the forecasts to:
Historical revenues and EBITDA.
Internal communications to management and the Board of Directors.
Forecasted information included in industry reports for the Company and certain of its peer companies.
We evaluated the impact of changes in management’s forecasts from the October 1, 2021, annual measurement date to December 31, 2021.
With the assistance of our fair value specialists, we evaluated the reasonableness of management’s qualitative assessment by performing the following: (1) Researching GDP growth, inflation and/or other macroeconomic variables, as well as industry growth rates; (2) Estimate industry discount rates; (3) Research and analyze valuation multiple of guideline public companies to understand valuation trends, and research trends in growth and margins in guideline public companies; and (4) Obtain information to analyze the trend of market capitalization of the entity and public peer companies.

Recently Issued Accounting Pronouncements
In August 2018,November 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)"2021-10, "Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance" ("ASU 2018-14"2021-10"), which modifies the disclosure requirementsrequires annual disclosures about transactions with a government that are accounted for employers who sponsor defined benefit pensionby applying a grant or other postretirement plans.contribution accounting model by analogy. ASU 2018-142021-10 is effective for fiscal years ending after December 15, 2020, with early adoption permitted. ASU 2018-14 is to be applied retrospectively to all periods presented. The Company is in the process of assessing the impact of adoption on its consolidated financial statements.
In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)" ("ASU 2018-02"), which provides for the option to reclassify stranded tax effects resulting from the Tax Cuts and Jobs Act ("Tax Reform Act") classified within accumulated other comprehensive income to retained earnings. ASU 2018-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. ASU 2018-02 is to be applied retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate related to the Tax Reform Act is recorded. The Company is in the process of assessing the impact of adoption on its consolidated financial statements.
In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"), which simplifies the test for goodwill impairment by eliminating the requirement to perform a hypothetical purchase price allocation to measure the amount of goodwill impairment. ASU 2017-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019,2021, with early adoption permitted.

3.3. Summary of Significant Accounting Policies
Principles of Consolidation.    The accompanying consolidated financial statements include the accounts and transactions of TriMas and its subsidiaries. Intercompany transactions have been eliminated.
Use of Estimates.    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management of the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. Such estimates and assumptions also affect the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the carrying amount of property and equipment, goodwill and other intangibles, valuation allowances for receivables, inventories and deferred income tax assets, valuation of derivatives, estimated future unrecoverable lease costs, reserves for asbestos and ordinary course litigation, assets and obligations related to employee benefits and estimated unrecognized tax benefits. Actual results may differ from such estimates and assumptions.
Cash and Cash Equivalents.    The Company considers cash on hand and on deposit and investments in all highly liquid debt instruments with initial maturities of three months or less to be cash and cash equivalents. Cash and cash equivalents also includes restricted cash held on deposit with a financial institution as cash collateral for the Company's outstanding letters of credit. See Note 8, "Cash and Cash Equivalents," for further details regarding the Company's cash and cash equivalents.
Receivables.    Receivables are presented net of allowances for doubtful accounts of approximately $3.4$1.6 million and $4.1$2.1 million at December 31, 20182021 and 2017,2020, respectively. The Company monitors its exposure for credit losses and maintains allowances for doubtful accounts based upon the Company's best estimate of probable losses inherent in the accounts receivable balances. The Company does not believe that significant credit risk exists due to its diverse customer base.
Sales
52

Table of Receivables.    The Company may, from time to time, sell certain of its receivables to third parties. Sales of receivables are recognized at the point in which the receivables sold are transferred beyond the reach of the Company and its creditors, the purchaser has the right to pledge or exchange the receivables and the Company has surrendered control over the transferred receivables.Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Inventories.    Inventories are stated at the lower of cost or net realizable value, with cost determined using the first-in, first-out method. Direct materials, direct labor and allocations of variable and fixed manufacturing-related overhead are included in inventory cost.
Property and Equipment.    Property and equipment additions, including significant improvements, are recorded at cost. Upon retirement or disposal of property and equipment, the cost and accumulated depreciation are removed from the accounts, and any gain or loss is included in the accompanying statement of operations. Repair and maintenance costs are charged to expense as incurred.
Depreciation and Amortization.    Depreciation is computed principally using the straight-line method over the estimated useful lives of the assets. Annual depreciation rates are as follows: building and land/building improvements three to 40 years, and machinery and equipment, three to 15 years. Capitalized debt issuance costs are amortized over the underlying terms of the related debt securities. Customer relationship intangibles are amortized over periods ranging from five to 25 years, while technology and other intangibles are amortized over periods ranging from one to 30 years.
Impairment of Long-Lived Assets and Definite-Lived Intangible Assets.    The Company reviews, on at least a quarterly basis, the financial performance of its businesses for indicators of impairment. In reviewing for impairment indicators, the Company also considers events or changes in circumstances such as business prospects, customer retention, market trends, potential product obsolescence, competitive activities and other economic factors. An impairment loss is recognized when the carrying value of an asset group exceeds the future net undiscounted cash flows expected to be generated by that asset group. The impairment loss recognized is the amount by which the carrying value of the asset group exceeds its fair value.
Goodwill.    The Company assesses goodwill for impairment on an annual basis (October 1 test date) by reviewing relevant qualitative and quantitative factors. More frequent evaluations may be required if the Company experiences changes in its business climate or as a result of other triggering events that take place. IfAn impairment loss is recognized when the carrying value of a reporting unit's goodwill exceeds its fair value, a possible impairment exists and further evaluation is performed.value.
The Company determines its reporting units at the individual operating segment level, or one level below, when there is discrete financial information available that is regularly reviewed by segment management for evaluatingto evaluate operating results. For purposes of the Company's 20182021 goodwill impairment test, the Company had five5 reporting units, three3 of which had goodwill, within its three3 reportable segments.  See Note 6, "Goodwill and Other Intangible Assets," for further details regarding the Company's goodwill impairment testing.

The Company begins its goodwill reviews by conducting a qualitative assessment, ("Step Zero"), considering relevant events and circumstances that affect the fair value or carrying amount of a reporting unit. Such events and circumstances can include macroeconomic conditions, industry and market considerations, overall financial performance, entity and reporting unit specific events, and capital markets pricing. The Company considers the extent to which each of theany identified adverse events and circumstances identified affect the comparison of a reporting unit's fair value with its carrying amount. The Company places more weight on the events and circumstances that most affect a reporting unit's fair value or the carrying amount of its net assets. The Company considers positive and mitigating events and circumstances that may affect its determination of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company also considers recent valuations of its reporting units, including the difference between the most recent fair value estimate and the carrying amount. TheseEach of these factors are allis considered by management in reaching its conclusion about whether a quantitative goodwill impairment test is necessary to estimate the fair value of its reporting units.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
If the Company concludes that conducting a quantitative assessment is required, it performs the first step of a two-stepquantitative goodwill impairment test. For the first step ("Step I"),When conducting a quantitative goodwill impairment test, the Company estimatesdetermines the fair value of the reporting unit being evaluated utilizing a combination of three valuation techniques: discounted cash flow (income approach), market comparable method (market approach) and market capitalization (direct market data method). The income approach is based on management's operating plan and internal five-year forecast and utilizes forward-looking assumptions and projections, on a discounted basis, but considers factors unique to each reporting unit and related long-range plans that may not be comparable to other companies and that are not yet public. The market approach considers potentially comparable companies and transactions within the industries where the Company's reporting units participate, and applies their trading multiples to the financial projections of the Company's reporting units. This approach utilizes data from actual marketplace transactions, but reliance on its results is limited by difficulty in identifying companies that are specifically comparable to the Company's reporting units, considering the diversity of the Company's businesses, the relative sizes and levels of complexity. The Company also uses the direct market data method by comparing its book value and the estimates of fair value of the reporting units to the Company's market capitalization. Management uses this comparison as additional evidence of the fair value of the Company, as its market capitalization may be suppressed by other factors such as the control premium associated with a controlling shareholder, the Company's degree of leverage and the float of the Company's common stock. Management evaluates and weights the results based on a combination of the income and market approaches, and, in situations where the income approach results differ significantly from the market and direct data approaches, management re-evaluates and adjusts, if necessary, its assumptions.
Based on the Step Iquantitative test, if it is determined that the carrying value of the reporting unit is higher than its fair value, there is an indication that an impairment may exist and the second step ("Step II") is performed to measure the amount of impairment loss, if any. In Step II, the Company determines the implied fair value of the reporting unit goodwill in the same manner as if the reporting unit was being acquired in a business combination and compares the implied fair value of the reporting unit goodwill to the carrying value of the goodwill. If the implied fair value of the goodwill is less than the carrying value, goodwill is impaired and is written down to the implied fair value amount.amount; however, the loss recognized will not exceed the total amount of goodwill allocated to the reporting unit. See Note 9, "Goodwill and Other Intangible Assets," for further details regarding the Company's goodwill impairment testing.
Indefinite-Lived Intangibles. The Company assesses indefinite-lived intangible assets (primarily trademark/trade names) for impairment on an annual basis (October 1 test date) by reviewing relevant qualitative and quantitative factors. More frequent evaluations may be required if the Company experiences changes in its business climate or as a result of other triggering events that take place. IfAn impairment loss is recognized when the carrying value of the asset exceeds its fair value, a possible impairment exists and further evaluation is performed.value.
In conducting a qualitative assessment, the Company considers relevant events and circumstances to determine whether it is more likely than not that the fair values of the indefinite-lived intangible assets are less than the carrying values. In addition to the events and circumstances that the Company considers above in its qualitative analysis for potential goodwill impairment, the Company also considers legal, regulatory and contractual factors that could affect the fair value or carrying amount of the Company's indefinite-lived intangible assets. The Company also considers recent valuations of its indefinite-lived intangible assets, including the difference between the most recent fair value estimates and the carrying amounts. These factors are all considered by management in reaching its conclusion about whether it is more likely than not that the fair values of the indefinite-lived intangible assets are less than the carrying values. If management concludes that further testing is required, the Company performs a quantitative valuation to estimate the fair value of its indefinite-lived intangible assets. In conducting the quantitative impairment analysis, the Company determines the fair value of its indefinite-lived intangible assets using the relief-from-royalty method. The relief-from-royalty method involves the estimation of appropriate market royalty rates for the indefinite-lived intangible assets and the application of these royalty rates to forecasted net sales attributable to the intangible assets. The resulting cash flows are then discounted to present value, using a rate appropriately reflecting the risks inherent in the cash flows, which then is compared to the carrying value of the assets. If the carrying value exceeds fair value, an impairment is recorded. See Note 6,9, "Goodwill and Other Intangible Assets," for further details regarding the Company's indefinite-lived intangible asset impairment testing.

High Deductible Insurance.    The Company generally has a high deductible insurance planprograms for losses and liabilities related to workers' compensation, health and welfare claims and comprehensive general, product and vehicle liability. The Company is generally responsible for up to $0.8 million per occurrence under its retention program for workers' compensation, between $0.3 million andup to $1.5 million per occurrence under its retention programs for comprehensive general, product and vehicle liability, and has a $0.3$0.4 million per occurrence stop-loss limit with respect to its group medical plan. Total insurance limits under these retention programs vary by year for comprehensive general, product and vehicle liability and extend to the applicable statutory limits for workers' compensation. Reserves for claims losses, including an estimate of related litigation defense costs, are recorded based upon the Company's estimates of the aggregate liability for claims incurred using actuarial assumptions about future events. Changes in assumptions for factors such as medical costs and actual experience could cause these estimates to change.
Pension Plans.    The Company engages independent actuaries to compute the amounts of liabilities and expenses under defined benefit pension plans, subject to the assumptions that the Company determines are appropriate based on historical trends, current market rates and future projections. Assumptions used in the actuarial calculations could have a significant impact on plan obligations, and a lesser impact on current period expense. Annually, the Company reviews the actual experience compared to the more significant assumptions used and makes adjustments to the assumptions, if warranted. Discount rates are based on an expected benefit payments duration analysis and the equivalent average yield rate for high-quality fixed-income investments. Pension benefits are funded through deposits with trustees and the expected long-term rate of return on fund assets is based on actual historical returns and a review of other public company pension asset return data, modified for known changes in the market and any expected change in investment policy. See Note 18, “Employee Benefit Plans,” for further information.
Asbestos-related Matters. The Company accrues loss reserves for asbestos-related matters based upon an estimate of the ultimate liability for claims incurred, whether reported or not, including an estimate of future settlement costs and costs to defend. The Company utilizes known facts and historical trends for Company-specific and general market asbestos-related activity, as well as an actuarial valuation in determining estimated required reserves which it believes are probable and reasonably estimable. Asbestos-related accruals are assessed at each balance sheet date to determine if the liability remains reasonably stated. Accruals for asbestos-related matters are included in the consolidated balance sheet in “Accrued liabilities” and “Other long-term liabilities.” See Note 17, “Commitments and Contingencies,” for further information.
Revenue Recognition.    Revenue is recognized when control of promised goods areis transferred to customers, which generally occurs when products are shipped from the Company’s facilities to its customers. The amount of revenue recorded reflects the consideration the Company expects to be entitled to receive in exchange for transferring those goods. Net sales are comprised of gross revenues, based on observed stand-alone selling prices, less estimates of expected returns, trade discounts and customer allowances, which include incentives such as volume and other discounts in connection with various supply programs. Such deductions are estimated and recorded during the period the related revenue is recognized. The Company may adjust these estimates when the expected amount of consideration changes based on sales volumes or other contractual terms. Sales and other consumption taxes the Company collects from customers and remits to government agencies are excluded from revenue. The Company accounts for freight and shipping costs that occur after control of the related goods transfer to the customer as a fulfillment cost within cost of sales. The nature and timing of the Company's revenue transactions are similar, as substantially all revenue is based on point-in-time transactions with customers under industry-standard payment terms. The Company may require shortened payment terms, including cash-in-advance, on an individual customer basis depending on its assessment of the customer's credit risk.worthiness.
Cost of Sales.    Cost of sales includes material, labor and overhead costs incurred in the manufacture of products sold in the period. Material costs include raw material, purchased components, outside processing and freight costs. Overhead costs consist of variable and fixed manufacturing costs, wages and fringe benefits, and purchasing, receiving and inspection costs.
Selling, General and Administrative Expenses.    Selling, general and administrative expenses include the following: costs related to the advertising, sale, marketing and distribution of the Company's products, amortization of customer intangible assets, costs of finance, human resources, legal functions, executive management costs and other administrative expenses.

Income Taxes.    The Company computes income taxes using the asset and liability method, whereby deferred income taxes using current enacted tax rates are provided for the temporary differences between the financial reporting basis and the tax basis of assets and liabilities and for operating loss and tax credit carryforwards. The Company determines valuation allowances based on an assessment of positive and negative evidence on a jurisdiction-by-jurisdiction basis and records a valuation allowance to reduce deferred tax assets to the amount more likely than not to be realized. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense.
On December 22, 2017, the Tax Reform Act was signed into law. Among the provisions, the Tax Reform Act reduces the Federal statutory corporate income tax rate from 35% to 21% effective January 1, 2018, implements a territorial tax system and imposes a one-time tax on the deemed repatriation of undistributed earnings of non-U.S. subsidiaries, introduces additional limitations on the deductibility of interest, allows for the immediate expensing of capital expenditures through 2023 and modifies or repeals many business deductions and credits.

While the Tax Reform Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The FASB provided guidance that allows companies to make an accounting policy election to either account for deferred taxes related to GILTI inclusions or treat any taxes on GILTI inclusions as period costs. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts on GILTI in its consolidated financial statements for the years ended December 31, 2018 and 2017.
The BEAT provisions in the Tax Reform Act eliminate the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. The Company does not expect the BEAT provisions to have a significant impact to its consolidated financial statements, and has not included any tax impacts of BEAT in its consolidated financial statements for the year ended December 31, 2018 and 2017.
See Note 19,23, "Income Taxes," for further information regarding the impact of the Tax Reform Act to the Company.information.
Foreign Currency Translation.    The financial statements of subsidiaries located outside of the United States are measured using the currency of the primary economic environment in which they operate as the functional currency. When translating into U.S. dollars, income and expense items are translated at average monthly exchange rates and assets and liabilities are translated at exchange rates in effect at the balance sheet date. Adjustments resulting from translating the functional currency into U.S. dollars are deferred as a component of accumulated other comprehensive income (loss) ("AOCI") in the consolidated statement of shareholders' equity. NetThe impact of net foreign currency transaction gains (losses) weretransactions was an approximate gainloss of $1.3$0.9 million for the year ended December 31, 2018, a loss2021, and approximate gains of $0.8$0.6 million and $0.3 million for the yearyears ended December 31, 20172020 and a gain of $0.8 million for the year ended December 31, 2016,2019, respectively, and are included in other expense, net in the accompanying consolidated statement of operations.
Derivative Financial Instruments.    The Company records derivative financial instruments at fair value on the balance sheet as either assets or liabilities, and changes in their fair values are immediately recognized in earnings if the derivatives do not qualify as effective hedges. If a derivative is designated as a fair value hedge, then changes in the fair value of the derivative are offset against the changes in the fair value of the underlying hedged item. If a derivative is designated as a cash flow hedge, then the effective portion of the changes in the fair value of the derivative is recognized as a component of other comprehensive income until the underlying hedged item is recognized in earnings or the forecasted transaction is no longer probable of occurring. If a derivative is designated as a net investment hedge, then the effective portion of the changes in the fair value of the derivative is recognized in other comprehensive income and will be subsequently reclassified to earnings when the hedged net investment is either sold or substantially liquidated. The Company formally documents hedging relationships for allits derivative transactions and the underlying hedged items, as well as its risk management objectives and strategies for undertaking the hedge transactions. See Note 11,14, "Derivative Instruments," for further information on the Company's financial instruments.information.
Fair Value of Financial Instruments.   In accounting for and disclosing the fair value of financial instruments, the Company uses the following hierarchy:
Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date;
Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and
Level 3 inputs are unobservable inputs for the asset or liability.
Valuation of the Company's interest rate swaps and cross-currency swaps are based on the income approach, which uses observable inputs such as interest rate yield curves and forward currency exchange rates, as applicable.
The carrying value of financial instruments reported in the balance sheet for current assets and current liabilities approximates fair value due to the short maturity of these instruments.

Business Combinations. The Company records assets acquired and liabilities assumed from acquisitions at fair value. The fair value of working capital accounts generally approximates book value. The valuation of inventory, property, plant and equipment, and intangible assets requires significant assumptions. Inventory is recorded at fair value based on the estimated selling price less costs to sell, including completion, disposal and holding period costs with a reasonable profit margin. Property and equipment is recorded at fair value using a combination of both the cost and market approaches for both the real and personal property acquired. Under the cost approach, consideration is given to the amount required to construct or purchase a new asset of equal value at current prices, with adjustments in value for physical deterioration, as well as functional and economic obsolescence. Under the market approach, recent transactions for similar types of assets are used as the basis for estimating fair value. For trademark/trade names and technology and other intangible assets, the estimated fair value is based on projected discounted future net cash flows using the relief-from-royalty method. For customer relationship intangible assets, the estimated fair value is based on projected discounted future cash flows using the excess earnings method. The relief-from-royalty and excess earnings method are both income approaches that utilize key assumptions such as forecasts of revenue and expenses over an extended period of time, royalty rate percentages, tax rates, and estimated costs of debt and equity capital to discount the projected cash flows.
Stock-based Compensation.  The Company recognizes compensation expense related to equity awards based on their fair values as of the grant date. For awards with only a service condition, expense is recognized ratably over the vesting period. Performance based equity awards may have targets tied to performance and/or market-based conditions. Market-based conditions are taken into consideration in determining the grant date fair value, and the related compensation expense is recognized regardless of whether the market condition is satisfied, provided the requisite service has been provided. For performance condition components, the Company periodically updates the probability that the performance conditions will be achieved and adjusts expense accordingly, reflecting the change from prior estimate, if any, in current period non-cash stock compensation expense. The disclosed number of awards granted considers only the targeted number of units until such time that the performance condition has been satisfied. If the performance conditions are not achieved, no award is earned. See Note 19, “Equity Awards,” for further information.
Other Comprehensive Income (Loss).  The Company refers to other comprehensive income (loss) as revenues, expenses, gains and losses that under accounting principles generally accepted in the United States of America are included in comprehensive income (loss) but are excluded from net earnings as these amounts are recorded directly as an adjustment to stockholders' equity. Other comprehensive income (loss) is comprised of foreign currency translation adjustments, amortization of prior service costs and unrecognized gains and losses in actuarial assumptions for pension and postretirement plans and changes in unrealized gains and losses on derivatives.derivative instruments.
Reclassifications.  Certain prior year amounts have been reclassified to conform with the current year presentation.

6.9. Goodwill and Other Intangible Assets
Goodwill
The Company performed a Step Zero qualitative assessment as part of its 2018, 20172021, 2020 and 20162019 annual impairment tests (October 1 annual test date) for all reporting units, which included a review of the Company’s market capitalization. For purposesBased on results of the 2018qualitative assessments for the 2021, 2020 and 2019 annual impairment test, based on the Step Zero assessment,tests, the Company determined there were no indications that the fair value of a reporting unit was less than its carrying amount. Therefore,amount; therefore, the Company determined that quantitative goodwill impairment tests were not required.
During the third quarter of 2020, as a result of a decline in its aerospace-related business' financial results, a significant reduction in its financial projections for the remainder of 2020 compared with prior projections, and uncertainty around the duration and magnitude of the impact of the COVID-19 pandemic on future financial results given their dependence on future levels of air travel and new aircraft builds, the Company determined there was a triggering event requiring an interim quantitative goodwill impairment assessment of each of its two aerospace-related reporting units: Aerospace Fasteners and Aerospace Engineered Products.
Upon completion of the quantitative goodwill impairment tests, the Company determined that the Step I and Step II tests were not required. For purposes of the 2017 and 2016 annual impairment tests, for all reporting units with goodwill other than the Aerospace reporting unit, based on the Step Zero assessment, the Company determined that there were no indications that the fair value of a reporting unit was less than its carrying amount. Therefore, the Company determined that the Step I and Step II tests were not required for these reporting units.
For purposes of the 2017 annual impairment test for the Company's Aerospace reporting unit, management elected to perform a Step I quantitative assessment in consideration of the partial goodwill impairment charge recorded during 2016. In preparing the Step I analysis, the Company utilized both income and market-based approaches, placing a 50% weighting on each. Significant management assumptions used under the income approach were a weighted average cost of capital ("WACC") of 9.5% and an estimated residual growth rate of 3%. In determining the WACC, management considered the level of risk inherent in the cash flow projections based on reducing previously utilized sales growth and margin expansion assumptions, as well as historical attainment of its projections and current market conditions. The use of these unobservable inputs resulted in the fair value estimate being classified as a Level 3 measurement within the fair value hierarchy. Upon completion of the Step I test, the Company determined that the fair valuevalues of the Aerospace Fasteners and Aerospace Engineered Products reporting units exceeded their fair values, resulting in goodwill impairment charges of approximately $70.8 million in its Aerospace Fasteners reporting unit exceededand approximately $56.0 million in its carrying value by more than 15%.Aerospace Engineered Products reporting unit.

In the first quarter of 2020, the Company began reporting its machined components operations within the Aerospace segment. These operations were previously reported in the Company's Specialty Products segment. As a result of the reporting structure change, goodwill of approximately $12.7 million was reassigned from the Specialty Products segment to the Aerospace segment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

For purposes of the 2016 annual impairment test for the Company's Aerospace reporting unit, management had been monitoring current and expected operating results since the first quarter of 2016, when sales and margins were significantly lower than expected, to assess whether the reductions were other than temporary. Management established and executed against recovery plans, improving sales and margin levels during the second and third quarters of 2016. However, when considering these recent financial results, plus recognizing that fourth quarter 2016 results would be lower than previously expected, and updating the Company's assessment of future expectations for growth and profit levels, the Company determined that there were indicators that the fair value of the Aerospace reporting unit was less than its carrying value. Therefore, the Company performed a Step I quantitative assessment for its Aerospace reporting unit utilizing both income and market-based approaches, placing a 50% weighting on each. Significant management assumptions used under the income approach were a WACC of 10.3% and an estimated residual growth rate of 3%. In determining the WACC, management considered the level of risk inherent in the cash flow projections and current market conditions. The use of these unobservable inputs resulted in the fair value estimate being classified as a Level 3 measurement within the fair value hierarchy.
Upon completion of the 2016 Step I test, the Company determined that the carrying value of the Aerospace reporting unit exceeded its fair value. The Company then performed a Step II test to determine whether goodwill had been impaired and, if applicable, to calculate the amount of the impairment charge. Based on the results of the Step II goodwill impairment test, the Company recorded a goodwill impairment charge of approximately $60.2 million in its Aerospace reporting unit.

For the purposes of the Company's 20182021, 2020 and 2019 annual indefinite-lived intangible asset impairment tests (as of October 1), the Company performed a qualitative assessment to determine whether it was more likely than not that the fair values of the indefinite-lived intangible assets are less than the carrying values. Based on the qualitative assessment performed, the Company does not believe that it is more likely than not that the fair values of each of its indefinite-lived intangible assets are less than the carrying values; therefore, a fair value calculation of the indefinite-lived intangible assets is not required for the 2018 annual indefinite-lived intangible asset impairment tests.
In 2017, the Company performed a qualitative assessment as part of its annual impairment test to determine whether it was more likely than not that the fair values of the indefinite-lived intangible assets were less than the carrying values. Based on the qualitative assessment performed, the Company determineddid not believe that there were no indicationsit is more likely than not that the fair values of anyeach of its indefinite-lived intangible assets were less than the carrying values. However, in consideration of the impairment charge recorded during 2016, the Company performed a quantitative assessment for its indefinite-lived intangible assets recorded on its balance sheet as of October 1, 2017 within the Aerospace reportable segment to supplement its qualitative assessment. Using the relief-from-royalty method with a discount rate of 9.5% and an estimated residual growth rate of 3%, the Company determined each of its Aerospace-related trade names hadvalues; therefore, a fair value that exceeded carrying values by more than 9%. The use of unobservable inputs resulted in the fair value estimates being classified as a Level 3 measurement within the fair value hierarchy.

The agreements had a five year tenor at notional amounts declining from $150.0 million to $75.0 million over the contract period. Under the terms of the swap agreements, the Company was to receive net interest payments at a fixed rate of approximately 2.1% of the notional amount.
The Company has historically utilized interest rate swap agreements to fix the LIBOR-based variable portion of the interest rate on its long-term debt. Prior to its debt refinancing in September 2017, the Company had interest rate swap agreements in place that hedged a declining notional value of debt ranging from approximately $238.4 million to approximately $192.7 million, amortizing consistent with future scheduled debt principal payments. The interest rate swap agreements required the Company to receive a variable interest rate and pay a fixed interest rate in a range of 0.74% to 2.68% with various expiration terms extending to June 30, 2020. At inception, the interest rate swaps were designated as cash flow hedges.

In September 2017, immediately following the debt refinancing, the Company determined the likelihood of the hedged transactions occurring was not probable and de-designated the interest rate swaps as cash flow hedges and terminated the interest rate swaps for a cash payment of approximately $4.7 million. There were no interest rate swaps outstanding as of December 31, 2017. The cash flows associated with the cash flow hedges are reported in net cash provided by operating activities in the accompanying consolidated statement of cash flows. Up to the date of the termination, the Company utilized hedge accounting, which allows for the effective portion of the interest rate swaps to be recorded in AOCI in the accompanying consolidated balance sheet. At the date the Company de-designated the swaps as effective hedges, there was approximately $2.9 million (net of tax of $1.8 million) of unrealized losses remaining in AOCI, which were reclassified into debt financing and related expenses in the accompanying consolidated statement of operations during 2017.amounts.

Derivatives Not Designated as Hedging Instruments
As of December 31, 2021, the Company was party to foreign currency exchange forward contracts to economically hedge changes in foreign currency rates with notional amounts of approximately $131.8 million. The Company uses foreign exchange contracts to mitigate the risk associated with fluctuations in currency rates impacting cash flows related to certain of its receivables, payables and intercompany transactions denominated in foreign currencies. The foreign exchange contracts primarily mitigate currency exposures between the U.S. dollar and the Euro, Canadian dollar, Chinese yuan, and the Mexican peso, as well as between the Euro and British pound, and have various settlement dates through December 2022. These contracts are not designated as hedging instruments; therefore, gains and losses on these contracts are recognized each period directly into the consolidated statement of operations.

Environmental
The Company is subject to increasingly stringent environmental laws and regulations, including those relating to air emissions, wastewater discharges and chemical and hazardous waste management and disposal. Some of these environmental laws hold owners or operators of land or businesses liable for their own and for previous owners' or operators' releases of hazardous or toxic substances or wastes. Other environmental laws and regulations require the obtainment and compliance with environmental permits. To date, costs of complying with environmental, health and safety requirements have not been material. However, the nature of the Company's operations and the long history of industrial activities at certain of the Company's current or former facilities, as well as those acquired, could potentially result in material environmental liabilities.
While the Company must comply with existing and pending climate change legislation, regulation and international treaties or accords, current laws and regulations have not had a material impact on the Company's business, capital expenditures or financial position. Future events, including those relating to climate change or greenhouse gas regulation, could require the Company to incur expenses related to the modification or curtailment of operations, installation of pollution control equipment or investigation and cleanup of contaminated sites.

In addition, the Company acquired various companies to distribute its products that had distributed gaskets of other manufacturers prior to acquisition. The Company believes that many of the pending cases relate to locations at which none of its gaskets were distributed or used.
The Company may be subjected to significant additional asbestos-related claims in the future, theand will aggressively defend or reasonably resolve, as appropriate. The cost of settling cases in which product identification can be made may increase, and the Company may be subjected to further claims in respect of the former activities of its acquired gasket distributors. The Company is unable to make a meaningful statement concerning the monetarycost of claims made in the asbestos cases given that, among other things,varies as claims may be initially made in some jurisdictions without specifying the amount sought or by simply stating the requisite or maximum permissible monetary relief, and may be amended to alter the amount sought.The large majority of claims do not specify the amount sought.Of the 4,8204,754 claims pending at December 31, 2018, 492021, 27 set forth specific amounts of damages (other than those stating the statutory minimum or maximum). At December 31, 2018,2021, of the 4927 claims that set forth specific amounts, there were no claimswas 1 claim seeking specific amountsmore than $5 million for punitive damages. Below is a breakdown of the amountcompensatory damages sought for those claims seeking specific amounts:

In addition, relativelyRelatively few of the claims have reached the discovery stage and even fewer claims have gone past the discovery stage.
Total settlement costs (exclusive of defense costs) for all such cases, some of which were filed over 25 years ago, have been approximately $8.9 million.$10.6 million. All relief sought in the asbestos cases is monetary in nature. To date, approximately 40% of the Company's costs related to settlement and defense of asbestos litigation have been covered by its primary insurance. Effective February 14, 2006, the Company entered into a coverage-in-place agreement with its first level excess carriers regarding the coverage to be provided to the Company for asbestos-related claims when the primary insurance is exhausted. The coverage-in-place agreement makes asbestos defense costs and indemnity insurance coverage available to the Company that might otherwise be disputed by the carriers and provides a methodology for the administration of such expenses. The Company's primary insurance exhausted in November 2018, and the Company will be solely responsible for defense costs and indemnity payments prior to the commencement of coverage under this agreement, the duration of which would be subject to the scope of damage awards and settlements paid.
Based on the settlements made to date and the number of claims dismissed or withdrawn for lack of product identification, the Company believes that the relief sought (when specified) does not bear a reasonable relationship to its potential liability.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
There has been significant volatility in the historical number of claim filings and costs to defend, with previous claim counts and spend levels much higher than current levels. Management believes this volatility was associated more with tort reform, plaintiff practices and state-specific legal dockets than the Company’s underlying asbestos-related exposures. From 2017 to 2019, however, the number of new claim filings, and costs to defend, had become much more consistent. The higher degree of consistency in census data and spend levels, as well as lower claim activity levels and an evolving defense strategy, has allowed the Company to more effectively and efficiently manage claims, making process or local counsel arrangement improvements where possible. Given the consistency of activity over a multi-year period, the Company believes a trend may have formed where it could be possible to reasonably estimate its future cash exposure for all asbestos-related activity with an adequate level of precision. As such, the Company commissioned an actuary to help evaluate the nature and predictability of its asbestos-related costs, and provide an actuarial range of estimates of future exposures. Based upon its review of the actuarial study, which was completed in June 2020 using data as of December 31, 2019 and which projected spend levels through a terminal year of 2064, the Company affirmed its belief that it now has the ability to reasonably estimate its future asbestos-related exposures for pending as well as unknown future claims.
During the second quarter of 2020, the Company elected to change its method of accounting for asbestos-related defense costs from accruing for probable and reasonably estimable defense costs associated with known claims expected to settle to accrue for all future defense costs for both known and unknown claims, which the Company now believes are reasonably estimable. The Company believes this change is preferable, as asbestos-related defense costs represent expenditures related to legacy activities that do not contribute to current or future revenue generating activities, and recording an estimate of the full liability for asbestos-related costs, where estimable with reasonable precision, provides a more complete assessment of the liability associated with resolving asbestos-related claims.
This accounting change was reflected as a change in accounting estimate effected by a change in accounting principle. Following the change in accounting estimate, the Company’s liability for asbestos-related claims will be based on a study from the Company’s third-party actuary, the Company's review of the study, as well as the Company’s own review of asbestos claims and claim resolution activity. After completing its study in the second quarter of 2020, the Company recorded a non-cash, pre-tax charge of $23.4 million, which is included in selling, general and administrative expenses in the accompanying consolidated statement of operations.
In 2021, the Company commissioned its actuary to update the asbestos study based on data as of September 30, 2021, which yielded a range of possible future liability of $28.2 million to $38.6 million. The Company did not believe any amount within the range of potential outcomes represented a better estimate than another given the many factors and assumptions inherent in the projections, and therefore recorded a non-cash, pre-tax charge of $1.5 million to increase the liability estimate to $28.2 million, at the low-end of the range. This charge is included in selling, general and administrative expenses in the accompanying consolidated statement of operations. As of December 31, 2021, the Company’s total asbestos-related liability is $27.6 million, and is included in accrued liabilities and other long-term liabilities, respectively, in the accompanying consolidated balance sheet.
The Company’s primary insurance, which covered approximately 40% of historical costs related to settlement and defense of asbestos litigation, expired in November 2018, upon which the Company became solely responsible for defense costs and indemnity payments. The Company is party to a coverage-in-place agreement (entered into in 2006) with its first level excess carriers regarding the coverage to be provided to the Company for asbestos-related claims. The coverage-in-place agreement makes asbestos defense costs and indemnity insurance coverage available to the Company that might otherwise be disputed by the carriers and provides a methodology for the administration of such expenses. The Company will continue to be solely responsible for defense costs and indemnity payments prior to the commencement of coverage under this agreement, the duration of which would be subject to the scope of damage awards and settlements paid. Based upon the Company’s review of the actuarial study, the Company does not believe it is probable that it will reach the threshold of qualified future settlements required to commence excess carrier insurance coverage under the coverage-in-place agreement.
Based upon the Company's experience to date, including the trend in annual defense and settlement costs incurred to date, and other available information (including the availability of excess insurance), the Company does not believe that these cases will have a material adverse effect on its financial position, and results of operations, or cash flows.
Metaldyne Corporation
Prior to 2002, the Company was wholly-owned by Metaldyne Corporation ("Metaldyne"). In connection with the reorganization between TriMas and Metaldyne in 2002, TriMas assumed certain liabilities and obligations of Metaldyne, mainly comprised of contractual obligations to former TriMas employees, tax related matters, benefit plan liabilities and reimbursements to Metaldyne of normal course payments to be made on TriMas' behalf.
In 2007, Metaldyne merged into a subsidiary of Asahi Tec Corporation (“Asahi”) whereby Metaldyne became a wholly-owned subsidiary of Asahi, and in 2009, Metaldyne and its U.S. subsidiaries filed voluntary petitions in the United States Bankruptcy Court under Chapter 11 of the U.S. Bankruptcy Code.
In January 2018, the U.S. Bankruptcy Court entered a final decree to close all remaining cases and finalize the Metaldyne bankruptcy distribution trust, effectively terminating any potential obligation by TriMas to Metaldyne. In consideration of the final decree, the Company removed the obligation from its balance sheet during the first quarter of 2018, resulting in an approximate $8.2 million non-cash reduction in selling, general and administrative expenses in the accompanying consolidated statement of operations.

The plan contains both contributory and noncontributory profit sharing arrangements, as defined. Aggregate charges included in the accompanying consolidated statement of operations under this plan for both continuing and discontinued operations were approximately $4.2 million, $3.8 million and $3.7$3.4 million in 2018, 2017both 2021 and 2016, respectively.2020 and $4.6 million in 2019.

The service cost component of net periodic benefit costexpense is recorded in cost of goods sold and selling, general and administrative expenses, while non-service cost components are recorded in other expense, net in the accompanying consolidated statement of operations.
During 2018, the Company recognized one-time settlement and curtailment charges of approximately $2.6 million, of which approximately $2.5 million was due to the purchase of an annuity contract to transfer certain U.S. retiree defined benefit obligations to an insurance company. The annuity contract was funded by plan assets.
During 2016, the Company recognized one-time settlement and curtailment charges of approximately $1.3 million primarily due to lump sum payments in the United States and the United Kingdom.
The estimated net actuarial loss and prior service cost for defined benefit pension plans that is expected to be amortized from AOCI into net periodic benefit expense in 2019 is approximately $0.6 million.
Actuarial valuations of the Company's defined benefit pension plans were prepared as of December 31, 2018, 20172021, 2020 and 2016.2019. Weighted average assumptions used in accounting for the U.S. defined benefit pension plans are as follows:

The Company utilizes a high-quality (Aa or greater) corporate bond yield curve as the basis for its domestic discount rate for its pension benefit plans. Management believes this yield curve removes the impact of including additional required corporate bond yields (potentially considered in the above-median curve) resulting from the uncertain economic climate that does not necessarily reflect the general trend in high-quality interest rates.

Plan Assets
The Company's overall investment goal is to provide for capital growth with a moderate level of volatility by investing assets in targeted allocation ranges. Specific long term investment goals include total investment return, diversity to reduce volatility and risk, and to achieve an asset allocation profile that reflects the general nature and sensitivity of the plans' liabilities. Investment goals are established after a comprehensive review of current and projected financial statement requirements, plan assets and liability structure, market returns and risks as well as special requirements of the plans. The Company reviews investment goals and actual results annually to determine whether stated objectives are still relevant and the continued feasibility of achieving the objectives.
The actual weighted average asset allocation of the Company's domestic and foreign pension plans' assets at December 31, 20182021 and 20172020 and target allocations by class, were as follows:

TRIMAS CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Actual allocations to each asset vary from target allocations due to periodic investment strategy changes, market value fluctuations and the timing of benefit payments and contributions. The expected long-term rate of return for both the domestic and foreign plans' total assets is based on the expected return of each of the above categories, weighted based on the target allocation for each class. Actual allocation is reviewed regularly and investments are rebalanced to their targeted allocation range when deemed appropriate.
In managing the plan assets, the Company reviews and manages risk associated with the funded status risk, interest rate risk, market risk, liquidity risk and operational risk. Investment policies reflect the unique circumstances of the respective plans and include requirements designed to mitigate these risks by including quality and diversification standards.

During 2020, the Company undertook certain tax-planning actions with respect to intercompany debt restructuring within the group. These actions resulted in the recognition of an approximate $6.4 million deferred tax benefit related to an interest limitation carryforward.
The Company has recorded deferred tax assets on $31.1approximately $34.0 million of various state operating loss carryforwards and $18.3$57.6 million of various foreign operating loss carryforwards. The majority of the state tax loss carryforwards expire between 20242026 and 20282032 and the majority of the foreign losses have indefinite carryforward periods.
The Company has not made a provision for U.S. or additional foreign withholding taxes related to investments in foreign subsidiaries that are indefinitely reinvested since any excess of the amount for financial reporting over the tax basis in these investments is not significant as of December 31, 2018.2021.

Unrecognized Tax Benefits
Tax Reform
In December 2017, the Tax Reform Act was signed into law, and, among the provisions, reduced the Federal statutory corporate income tax rate from 35% to 21% effective January 1, 2018, and implemented a territorial tax system, imposing a one-time tax on the deemed repatriation of undistributed earnings of non-U.S. subsidiaries ("Transition Tax"). The Transition Tax is payable over eight years beginning in 2019.
Coincident with the signing of the Tax Reform Act, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. SAB 118 provided up to a one-measurement period for companies to finalize the accounting for the impacts of this new legislation.
In 2017, the Company recognized an approximate $9.0 million provisional tax expense related to the Transition Tax, and an approximate $3.7 million provisional tax expense in connection with the revaluation of its ending net deferred tax assets resulting from the reduction in the Federal income tax rate, for a total of $12.7 million provisional tax expense related to the adoption of the Tax Reform Act.
In 2018, the Company finalized the measurement of these provisional expenses. The Company recognized an approximate $1.1 million income tax benefit in connection with finalizing the revaluation of its net deferred tax assets following the filing of the Company's 2017 corporate income tax return, and recognized an approximate $0.7 million income tax expense related to finalizing the Transition Tax, resulting in a $0.4 million net reduction in 2018 to the $12.7 million provisional tax expense recorded in 2017.
On January 15, 2019, the Internal Revenue Service finalized regulations that govern the Transition Tax. The Company is in the process of analyzing these regulations, but does not expect the regulations to have a significant impact on its consolidated financial statements.
Unrecognized tax benefits
The Company had approximately $3.0$1.3 million and $3.4$1.6 million of unrecognized tax benefits ("UTBs") as of December 31, 20182021 and 2017,2020, respectively. If the UTBs were recognized, the impact to the Company's effective tax rate would be to reduce reported income tax expense for the years ended December 31, 20182021 and 20172020 by approximately $2.5$1.1 million and $2.8$1.4 million,, respectively.

In addition to the UTBs summarized above, the Company has recorded approximately $1.8$0.8 million and $1.7$0.8 million in potential interest and penalties associated with uncertain tax positions as of December 31, 20182021 and 2017,2020, respectively.
The Company is subject to U.S. federal, state and local, and certain non-U.S. income tax examinations for tax years 20112014 through 2018.2021. In addition, there are currently several state and foreign income tax examinations in process. The Company does not believe that the results of these examinations will have a significant impact on the Company's tax position or its effective tax rate.
Management monitors changes in tax statutes and regulations and the issuance of judicial decisions to determine the potential impact to UTBs and is not aware of, nor does it anticipate, any material subsequent events that could have a significant impact on the Company's financial position during the next twelve months.

Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
Not applicable.
Item 9A.    Controls and Procedures
Evaluation of disclosure controls and procedures
As of December 31, 2018,2021, an evaluation was carried out by management, with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and Rule 15d-15(e) of the Securities Exchange Act of 1934 (the "Exchange Act")), pursuant to Rule 13a-15 of the Exchange Act. Our disclosure controls and procedures are designed only to provide reasonable assurance that they will meet their objectives. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of December 31, 2018,2021, the Company's disclosure controls and procedures were effective to provide reasonable assurance that they would meet their objectives.
We completed the acquisitions of TFI Aerospace ("TFI") and Omega Plastics ("Omega") in December 2021 and have not yet included TFI and Omega in our assessment of the effectiveness of our internal control over financial reporting. Accordingly, pursuant to the SEC's general guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our disclosure controls and procedures does not include TFI and Omega. For fiscal 2021, TFI and Omega accounted for approximately $0.3 million and $0.7 million of our total net sales, respectively, and as of December 31, 2021 had total assets of approximately $19.7 million and $28.5 million, respectively.
Management's Annual Report on Internal Control Over Financial Reporting
Management is responsible for the preparation and fair presentation of the consolidated financial statements included in this annual report. The consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles and reflect management's judgments and estimates concerning events and transactions that are accounted for or disclosed.
Management is also responsible for establishing and maintaining effective internal control over financial reporting. The Company's internal control over financial reporting includes those policies and procedures that pertain to the Company's ability to record, process, summarize, and report reliable financial data. Management recognizes that there are inherent limitations in the effectiveness of any internal control and effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Additionally, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time.
In order to ensure that the Company's internal control over financial reporting is effective, management regularly assesses such controls and did so most recently for its financial reporting as of December 31, 2018.2021. Management's assessment of internal control over financial reporting as of December 31, 2021 excludes internal control over financial reporting related to TFI and Omega (acquired in December 2021), which accounted for approximately $0.3 million and $0.7 million of our total net sales, respectively, and as of December 31, 2021 had total assets of approximately $19.7 million and $28.5 million, respectively. Management's assessment was based on criteria for effective internal control over financial reporting described in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management asserts that the Company has maintained effective internal control over financial reporting as of December 31, 2018.

Deloitte & Touche LLP, an independent registered public accounting firm, who audited the Company's consolidated financial statements, has also audited the effectiveness of the Company's internal control over financial reporting as of December 31, 2018,2021, as stated in their report below.
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of TriMas Corporation
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of TriMas Corporation and subsidiaries (the “Company”) as of December 31, 2018,2021, 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 20182021, of the Company and our report dated February 28, 2019,March 1, 2022, expressed an unqualified opinion on those financial statements and financial statement schedule.
As described in Management’s Annual Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at TFI Aerospace ("TFI") and Omega Plastics ("Omega"), which were acquired in December 2021, whose financial statements accounted for approximately $19.7 million and $28.5 million of total assets, respectively, and $0.3 million and $0.7 million of total net sales, respectively of the consolidated financial statements amounts as of and for the year ended December 31, 2021. Accordingly, our audit did not include the internal control over financial reporting at TFI and Omega.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
