PART I

Item 1. Business

Armstrong Flooring, Inc. ("AFI" or the "Company") is a Delaware corporation incorporated in 2015. When we refer to "we," "our," and "us" in this report, we are referring to Armstrong Flooring, Inc. and its consolidated subsidiaries.

We are a leading global producer of resilient flooring products for use primarily in the construction and renovation of commercial, residential and institutional buildings. We design, manufacture, source and sell flooring products primarily in North America and the Pacific Rim.

On April 1, 2016, we became an independent company as a result of the separation by Armstrong World Industries, Inc. ("AWI"), a Pennsylvania corporation, of its Resilient Flooring and Wood Flooring segments from its Building Products segment (the "Separation"). The Separation was effected by allocating the assets and liabilities related primarily to the Resilient Flooring and Wood Flooring segments to AFI and then distributing the common stock of AFI to AWI’s shareholders (the "Distribution"). The Separation and Distribution (together, the "Spin-off") resulted in AFI and AWI becoming two independent, publicly traded companies, with AFI owning and operating the Resilient Flooring and Wood Flooring segments and AWI continuing to own and operate a ceilings business.

In November 2018, we entered into a definitive agreement to sell our North American wood flooring business to Tarzan Holdco, Inc., a Delaware corporation and an affiliate of American Industrial Partners. The sale was completed on December 31, 2018. The historical financial results of the North American wood flooring business have been reflected in our Consolidated Financial Statements as a discontinued operation for all periods presented. Subsequent to the sale of the North American wood flooring business, the Company's results are part of a single reportable segment.

During early 2020, the Company established a multi-year strategic roadmap to transform and modernize its operations to become a leaner, faster-growing and more profitable business. The transformation encompasses three critical objectives: (i) expanding customer reach; (ii) simplifying product offerings and operations; and (iii) strengthening core capabilities. In addition, the Company has implemented a new operating model to more effectively accomplish these objectives by: (i) placing customers first by aligning services and products through a more seamless value chain; (ii) leading the industry in product innovation; (iii) simplifying processes and operating complexity to become more competitive and efficient; (iv) realigning the go-to-market model to reach all relevant channels and customers; (v) implementing system changes to improve operations, reduce costs and reignite organic growth; and (vi) investing thoughtfully with a return-focused mindset. The goal of this focused strategy is to transform and modernize AFI, resulting in a company that is more agile, faster-growing and more profitable.

Markets

We hold leadership or significant market share positions in the majority of the product categories and markets in which we operate. We compete exclusively in the resilient flooring product category in North America and the Pacific Rim. The majority of our sales are in North America, where we serve both commercial and residential markets. In the Pacific Rim, we are principally focused on commercial markets. Our business operates in a competitive environment across all our product categories and excess capacity exists in much of the industry.  We continue to see efforts by various competitors to price aggressively as a means to gain market share. The major markets in which we compete are:

North American Commercial — Our products are used in commercial, institutional buildings and multi-family housing. Our revenue opportunities come from new construction as well as renovation of existing buildings. Industry analysts estimate that renovation work represents the majority of the total North American commercial market opportunity. Most of our revenue comes from three major segments of commercial building: education, healthcare and retail. During 2020, the Company has also begun to explore expansion into the hospitality segment which represents a new growth opportunity. We monitor U.S. construction starts and follow project activity. Our revenue from new construction can lag behind construction starts by as much as twenty-four months given that the installation of flooring typically occurs later in the construction process. We also monitor architectural activity, gross domestic product ("GDP") and general employment levels, which can indicate movement in renovation and new construction opportunities. We believe that these statistics, taking into account the time-lag effect, provide a reasonable indication of our future revenue opportunity from commercial renovation and new construction. We also believe that consumer preferences for product type, style, color, availability, performance attributes and affordability significantly affect our revenue.

2

North American Residential — We sell products for use in single and multi-family housing. Homeowners, contractors, builders, and property management firms can choose from our innovative flooring products. We compete directly with other domestic and international suppliers of these products. Our flooring products also compete with carpet, stone, wood and ceramic products, which we do not offer.

Our products are used in new home construction and existing home renovation work. Industry analysts estimate that existing home renovation (also known as replacement/remodel) work represents a majority of the total North American residential market opportunity. We monitor key U.S. statistics including existing home sales (a key indicator for renovation opportunity), housing starts, housing completions, home prices, interest rates and consumer confidence. We believe there is some longer-term correlation between these statistics and our revenue after reflecting a lag period of several months between a change in these indicators and our operating results. However, we believe that consumers’ preferences for product type, style, color, availability, performance attributes and affordability also significantly affect our revenue. Further, changes in inventory levels and/or product focus at national home centers and independent wholesale flooring distributors can significantly affect our revenue.

Outside of North America — We also serve commercial markets in the Pacific Rim region with approximately 90% of the sales in this region coming from China and Australia. The commercial segments we serve are similar to the North American market (healthcare, education, and retail). However, there is a higher penetration of resilient flooring in the hospitality and infrastructure segments in China than we see in North America. For the countries where we have significant revenue, we monitor various national statistics (such as GDP) as well as construction data (starts and project-related information).

The following table provides an estimate of our net sales, by major markets(a):

North American Commercial		North American Residential		Outside of North America
New	Renovation	New	Renovation	New	Renovation	Total
10%	30%	5%	40%	10%	5%	100%

(a) Management has estimated the above data as the ultimate end-use of our products is not easily determinable. Management believes these estimates to be consistent year-over-year.

Demand for our products is influenced by economic conditions. We closely monitor publicly available macroeconomic trend data that provides insight to commercial and residential market activity; this includes GDP growth indices, the Architecture Billings Index and the Consumer Confidence Index, as well as housing starts and existing home sales. In addition, our channel partners raise or lower their inventory levels according to their expectations of market demand and consumer preferences, which directly affects our sales.

Products

Luxury vinyl tile ("LVT") - LVT represents the fastest growing resilient flooring product category. Through enhanced wear layers and coatings, LVT delivers improved durability and lower maintenance over traditional vinyl tile. In addition, the utilization of advanced printing and embossing technology provides LVT with upgraded visual realism in a wide variety of attractive wood and stone designs. LVT’s modular format offers a wide range of installation options for the professional and do-it-yourself installer, with an enhanced ease of installation when compared to other products such as wood or ceramic tile; this can be seen with the growing popularity of floating and rigid LVT floors. The largest market for LVT is North America. We believe LVT growth has and will continue to come partially at the expense of other product categories in both the soft and hard surface flooring markets.

Vinyl composition tile ("VCT") - VCT is a flooring material composed of polyvinylchloride ("PVC") chips formed into solid sheets and cut into modular shapes that offers a classic look and economical value. We are the largest producer of VCT which is primarily used in commercial environments. The market for VCT is a mature and well-structured category and has continued to experience a softening in demand due to customer trends, which have continued to favor alternate products, including LVT products.

Vinyl sheet - Vinyl sheet is a resilient flooring product that comes in a roll that is cut to size. Vinyl sheet performs in high-traffic settings and is low maintenance. Our product Rejuvenations™ Restore™ addresses heath care concerns of both comfort and sound. We produce and sell vinyl sheet product for both residential and commercial markets. We continue to experience a decline in demand for our traditional resilient products, particularly residential vinyl sheet products. The decline in vinyl sheet is driven by loss of market share to competitors as well as consumer trends, which have continued to favor alternate products, including LVT products. During 2020, we introduced the industry's first non-PVC vinyl sheet system, Medinpure™, for use in healthcare applications, which was recognized by many trade publications and industry organizations.

Customers

We use our reputation, capabilities, service and brand recognition to develop long-standing relationships with our customers. We sell products through both independent wholesale flooring distributors, who re-sell our products to retailers, builders, contractors, installers and others as well as direct to specialty retailers. In the commercial sector, we also have important relationships with subcontractors’ alliances, large architectural firms, large design firms and major facility owners in our focus segments. In the North American retail channel, which sells to end-users in the residential and light commercial segments, we have important relationships with several national home centers and flooring retailers. Additionally, we also have important relationships with major home builders and retail buying groups in the North American residential sector.

Approximately 75% of our consolidated net sales in 2020 were to distributors. Sales to large home centers accounted for approximately 16% of our consolidated sales in 2020. Our remaining sales were primarily to other retailers, end-use customers and contractors. One customer accounted for 10% or more of our total consolidated net sales in 2020.

Competition

We face strong competition in all of our businesses. Principal attributes of competition include product performance, product styling, service and price. Competition in North America comes from both domestic and international manufacturers. Additionally, some of our products compete with alternative products or finishing solutions. Our resilient flooring products compete with carpet, stone, wood, ceramic products, rubber and stained or polished concrete. There is excess industry capacity for certain products in some geographies, which tends to increase price competition. The following companies are our primary competitors: Beaulieu International Group N.V., Creative Flooring Solution, Congoleum Corporation, Engineered Floors, LLC, Forbo Holding AG, Gerflor Group, HMTX Industries (including Metroflor Corporation), Interface, Inc. (including Nora Systems GmbH), LG Floors, Mannington Mills, Inc., Mohawk Industries, Inc., Shaw Industries, Inc. and Tarkett AG. We also compete with private label brokers.

Raw Materials

We purchase raw materials from numerous suppliers worldwide in the ordinary course of business. The principal raw materials include: PVC resins and films, plasticizers, fiberglass and felt backings, limestone, pigments, inks, stabilizers and coatings.

We also purchase significant amounts of packaging materials and consume substantial amounts of energy, such as electricity, natural gas and water.

In general, adequate supplies of raw materials are available. However, availability can change for a number of reasons, including environmental conditions, laws and regulations, shifts in demand by other industries competing for the same materials, transportation disruptions and/or business decisions made by, or events that affect, our suppliers. If these suppliers were unable to satisfy our requirements, we believe alternative supply arrangements would be available.

Prices for certain high usage raw materials can fluctuate dramatically. Cost increases for these materials can have a significant adverse impact on our manufacturing costs. During the fourth quarter of 2020 there was a resin shortage due to a hurricane and COVID-19. This caused a temporary increase in the price of resin, which is used to make PVC.

Sourced Products

Some of our products are sourced from third parties. Our primary sourced products include LVT, vinyl sheet, installation and maintenance materials and accessories. We purchase most of our sourced products from suppliers that are located outside of the U.S., primarily from Asia. Sales of sourced products represented approximately 30% of our total consolidated revenue in 2020.

In general, adequate supplies of sourced products are available. However, availability can change for a number of reasons, including environmental conditions, laws and regulations including tariffs, production and transportation disruptions and/or business decisions made by, or events that affect, our suppliers. If these suppliers were unable to satisfy our requirements, we believe alternative supply arrangements would be available.

Recent trends in shipping have extended delivery times for certain products and materials, primarily from China and Vietnam. While we expect this to be temporary in nature, we cannot reasonably predict when the imbalance of global shipping capacity and demand will end.

4

Tariffs

Tariffs impact the cost of products we import from China. The U.S. government announced a tariff of 10% on certain flooring products imported to the U.S. from China, effective on September 24, 2018 with an additional 15% effective on May 10, 2019. In order to partially offset the impact, we implemented price increases that went into effect in the fourth quarter of 2018, and additional price increases that went into effect in the second quarter of 2019 on select impacted products. On November 8, 2019, an exclusion on tariffs of certain flooring products was announced. The exclusion applied retroactively to September 24, 2018. Additional products were added to the exclusion in the second quarter of 2020, also retroactive to September 24, 2018. The exclusions expired in August 2020. We filed for tariff refunds on these products in 2020 and recorded refunds as a reduction of previously recorded expense once formal approval was received. Upon expiration of the exclusion, we implemented a price increase on select impacted products to offset the expense of the tariffs.

Seasonality

Generally, our sales in North America tend to be stronger in the second and third quarters of our fiscal year due to more favorable weather conditions, customer business cycles and education renovations typical during the summer months. We see similar patterns with respect to our sales in the Pacific Rim, though the timing of the Chinese New Year can affect buying behaviors in the first fiscal quarter.

Patent and Intellectual Property Rights

Patent protection is important to our business. Our competitive position has been enhanced by U.S. and foreign patents on products and processes developed or perfected within AFI, including those before and after the Spin-off, or obtained through acquisitions and licenses. In addition, we benefit from our trade secrets for certain products and processes.

Patent protection extends for varying periods according to the date of patent filing or grant and the legal term of a patent in the various countries where patent protection is obtained. The actual protection afforded by a patent, which can vary from country to country, depends upon the type of patent, the scope of its coverage and the availability of legal remedies. Although we consider that, in the aggregate, our patents, licenses and trade secrets constitute a valuable asset of material importance to our business, we do not regard any of our businesses as being materially dependent upon any single patent or trade secret, or any group of related patents or trade secrets.

An example of patented technology includes Diamond 10® Technology, which is patented in the United States and certain other countries.

We own or have a license to use certain trademarks, including, without limitation, Armstrong®, Alterna®, BBT®, Diamond 10® Technology, Empower™, Excelon®, Imperial®, Initiator™, Inspiring Great Spaces®, Luxe Plank®, Medintech®, Empower™, Medinpure™, Memories™, Natural Creations®, Station Square™, StrataMax® and Vivero®, which are important to our business because of their significant brand name recognition. This includes the new Armstrong Flooring logos developed in 2020 to strengthen and differentiate the Armstrong Flooring brand. Trademark protection continues in some countries as long as the mark is used and continues in other countries as long as the mark is registered. Registrations are generally for fixed, but renewable, terms.

Sustainability

We believe that a commitment to positive environmental and social practices strengthens our organization, increases our connection with our stakeholders and helps us better serve our customers and communities. Through these commitments which are embedded in our corporate strategy, we see additional ways to create value for our stockholders, our employees, our customers and the wider world. As part of this commitment, the Company focuses on operating its global footprint with minimal impact on the environment and designing products with materials and processes that are safe for both people and the planet. As a company, we recover over 90% of our generated waste and operate a closed loop product take-back program which has recycled over 150 million pounds of post-consumer flooring (since program inception prior to the Spin-off). Solar installations at our China and Australia facilities have further reduced our carbon footprint. While water recirculation and rainwater harvesting projects have eliminated over 123 million gallons of water use since 2008. We provide our employees with ongoing support through education, training, development and leadership opportunities and we prioritize the safety and well-being of our employees, stakeholders and communities. We demonstrate our commitment to environmental and social matters in many ways that can be explored on our website at www.armstrongflooring.com.

Human Capital

Overview

Armstrong Flooring had 1,552 employees globally as of December 31, 2020. Our workforce spans 1,267 employees in the U.S. and 285 employees in Canada, Australia, China, the Philippines, Singapore and Vietnam combined.

We are evolving our culture and our human capital strategies to best serve all these employees and align with our growth strategies and the changing social environments. Fostering a culture that is values-based, responsible, ethical and inclusive motivates and empowers our employees. This culture enables us to attract and retain the most talented people, engage them in meaningful and inspiring work; and as a result, fulfill our business goals and objectives. Our human capital philosophy is simple: Invest in people and they will return your investment in dividends. We grow together, encouraging one another to develop our own unique skills and celebrating each individual’s uniqueness, to find fulfillment, success and advancement.

Health and Safety

A key focus of our shared community is on the health, safety and well-being of our employees. We engage in continuous physical safety programs throughout our manufacturing facilities and provide mental and physical well-being programs to all employees. We quickly implemented measures during the COVID-19 pandemic to ensure employee health, safety and well-being. In addition to encouraging all employees whose jobs permitted to work remotely, we closed our manufacturing facilities for two weeks to implement new safety protocols. We relied on the best science at the time to create new protocols such as:

•Temperature checks and touchless hand sanitizing stations throughout the plant

•Special proximity monitors to alert employees when they come within 6 feet of another person

In the U.S., we also provided free COVID-19 testing to all employees and waived sick pay/short-term disability waiting times to all employees. In order to encourage good mental and physical health we waived all fees for Teladoc visits and made other changes, including training, to promote physical and mental well-being.

Talent Development

We recognize that in order to drive innovation and operational excellence, we must attract, develop, motivate and retain diverse, world-class talent. Through the execution of our people strategy and management succession plan, we are working to expand our talent pipeline and build a workforce with the skills necessary to thrive in the workplace of the future. Our workforce development efforts are focused on ensuring that we will maintain our leadership position in the industry and continue to provide our customers with innovative flooring solutions. We utilize digital recruiting tools to remove roadblocks typically faced by diverse candidates in applying to positions so that we can obtain a strong diverse candidate pool.

Through regular employee engagement surveys, semi-annual talent reviews, real-time discussions, available employee communication channels and a focus on our Values; we monitor the needs and expectations of our employees and respond to meet these evolving employee needs. We provide employees with ongoing opportunities to grow and develop through many different programs, including professional and leadership development, continuous performance management internal mobility. These programs and activities increased our employee engagement ratings and led to a workforce dedicated to creating value.

Diversity, Equity & Inclusion

We recognize diversity, equity and inclusion ("DE&I") as a business imperative. We believe that our business accomplishments are a result of the efforts of our employees around the world and that a diverse employee population will result in a better understanding of our customers’ needs. We respect the attributes that make each individual unique, including those that can be seen and those that are acquired or learned. Our DE&I purpose is to evolve the organization and our culture to reflect the customers and communities we serve, where employees can be their authentic selves and where differences in background, thought and experience are welcomed, valued and celebrated. We demonstrate purposeful actions and incorporate intentional practices to drive these inclusive behaviors in our daily work. One key example is through changes to our recruiting program, where we have digitally enabled our process to broaden the applicant pool to diverse groups that have traditionally had difficulty accessing job opportunities. This has increased the diversity of our candidate pool and our hires.

We are committed to continually reviewing our operational practices and aligning DE&I initiatives with business objectives. Our DE&I commitment is demonstrated by the establishment of our Diversity, Equity & Inclusion Council which considers all parts of our employee experience to ensure that DE&I principles are incorporated into our talent acquisition strategies, development offerings and employee services. The Council is comprised of, and led by, our employees, with executive sponsorship up to and including our CEO.

6

Competitive Pay and Employee Benefits

We provide market-competitive compensation and benefits to our employees. Our pay programs are designed to be performance-based so that employees are paid based on performance that they can control. Our benefits programs are reviewed each year to ensure that we are meeting current practices in providing benefits that meet the health and safety needs of our employees. When special circumstances occur, such as the recent pandemic, we adjust our benefits to meet our employees’ needs.

Legal and Regulatory Proceedings

AFI’s manufacturing and research facilities are affected by various federal, state and local requirements relating to the discharge of materials and the protection of the environment. We make expenditures necessary for compliance with applicable environmental requirements at each of our operating facilities. These regulatory requirements continually change, therefore we cannot predict with certainty future expenditures associated with compliance with environmental requirements.

We are involved in various lawsuits, claims, investigations and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, relationships with suppliers, distributors and competitors, employees and other matters. For example, we are currently a party to various litigation matters that involve product liability, tort liability and other claims under a wide range of allegations, including illness due to exposure to certain chemicals used in the workplace, or medical conditions arising from exposure to product ingredients or the presence of trace contaminants. In some cases, these allegations involve multiple defendants and relate to legacy products that we and other defendants purportedly manufactured or sold. We believe these claims and allegations to be without merit and intend to defend them vigorously. While complete assurance cannot be given to the outcome of these proceedings, we do not believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows.

On November 15, 2019, a shareholder filed a putative class action complaint in the United States District Court for the Central District of California alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5, promulgated thereunder, based on alleged false and/or misleading statements or omissions made between March 6, 2018 and November 4, 2019.  On March 2, 2020, the court issued an order appointing a lead plaintiff and lead counsel.  On July 2, 2020, the lead plaintiff filed an amended complaint asserting similar violations and expanding the alleged class period to cover alleged false and/or misleading statements or omissions made between March 6, 2018 and March 3, 2020.  On November 30, 2020, the Company reached a settlement in principle to fully resolve this matter. The agreement, which is subject to final documentation and Court approval, provides in part for a settlement payment of $3.75 million in exchange for the dismissal and a release of all claims against the defendants in connection with the securities class action suit. Neither the Company nor any individual defendant admits any wrongdoing through the settlement agreement. On January 15, 2021, the lead plaintiff filed a motion for preliminary approval of the settlement. On February 23, 2021, the court granted preliminary approval of the settlement, preliminary certification of the settlement class and approval to provide notice to the class. The final settlement approval hearing is currently scheduled for July 19, 2021. The $3.75 million settlement payment will be paid by the Company’s insurance provider under its insurance policy. Payment is expected during 2021.

While complete assurance cannot be given to the outcome of these proceedings, we do not believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations, or cash flows.

We have not experienced a material adverse effect upon our capital expenditures or competitive position as a result of environmental control legislation and regulations. There were no material liabilities recorded at December 31, 2020 for potential environmental liabilities on a global basis that we consider probable and for which a reasonable estimate of the probable liability could be made. See Note 19, Litigation and Related Matters, in Part II, Item 8, "Financial Statements" and Part I, Item 1A, "Risk Factors" for additional information.

Item 1A. Risk Factors

Risks Related to our Business, Operations and Industry

Failure to successfully execute our strategy to transform and modernize our business and related investment costs may materially adversely affect our market position, financial condition, liquidity or results of operations.

In March 2020 we announced our strategy to transform and modernize our business, including through go-to-market efforts featuring expanded customer reach, simplification of our business processes, strengthened product innovation and optimized production capabilities. Our inability to execute and fund any of these strategies, including through any failure to invest sufficiently, or to realize intended revenue; margin; selling, general and administrative expenses; working capital or capital expenditure benefits or improvements, could have a material adverse effect on our financial condition, liquidity or results of operations.

We compete with numerous flooring manufacturers in highly competitive markets. Competition can affect customer preferences, reduce demand for our products, negatively affect our product sales mix, leverage greater financial resources, or cause us to lower prices, any or all which could adversely affect our financial condition, liquidity or results of operations.

Our markets are highly competitive. We compete for sales of flooring products with many manufacturers and independent distributors of resilient flooring as well as with manufacturers who also produce other types of flooring products. Some of our competitors have greater financial resources than we do. Competition can reduce demand for our products, negatively affect our product sales mix or cause us to lower prices. Our customers consider our products' performance, content and styling, as well as customer service and price when deciding whether to purchase our products. Shifting consumer preference in our highly competitive markets whether for performance, product content, styling preferences, or our inability to develop and offer new competitive performance features, could have an adverse effect on our sales. Regulatory action or new product standards could also steer consumers away from our products.

In addition, excess industry capacity for certain products in several geographic markets could lead to industry consolidation and/or increased price competition. We are also subject to potential increased price competition from overseas competitors, which may have lower cost structures.

Our failure to compete effectively through management of our product portfolio, by meeting consumer preferences, maintaining market share positions in our traditional categories and gaining market leadership in growth product categories such as LVT, could have a material adverse effect on our financial condition, liquidity or results of operations.

If the availability of direct materials (raw materials, packaging, sourced products, energy) decreases, or these costs increase and we are unable to pass along increased costs, our financial condition, liquidity or results of operations could be adversely affected.

The availability and cost of direct materials, including raw materials, packaging materials, energy and sourced products are critical to our operations. For example, we use substantial quantities of petrochemical-based raw materials in our manufacturing operations. The cost of some of these items has been volatile in recent years and availability has been limited at times. We source some materials from a limited number of suppliers, which, among other things, increases the risk of unavailability. We also source from overseas and could be subject to international trade costs, such as tariffs, transportation and foreign exchange rates, or international epidemics, including, without limitation, the COVID-19 outbreak. There is also a concentration of our sourced products in an emerging market, which subjects us to legislative, political, regulatory and economic volatility and vulnerability. This dependency and any limited availability could cause us to reformulate products or limit our production. Decreased access to direct materials and energy or significant increased cost to purchase these items, as well as increased transportation and trade costs, delays due to government-mandated initiatives in response to the COVID-19 and any corresponding inability to pass along such costs through price increases or meet demand requirements, as applicable, could have a material adverse effect on our financial condition, liquidity or results of operations.

Sales fluctuations to and changes in our relationships with key customers could have a material adverse effect on our financial condition, liquidity or results of operations.

Some of our business lines and markets are dependent on a few key customers, including independent distributors. The loss, reduction, or fluctuation of sales to one of these major customers, or any adverse change in our business relationship with any one of them, could have a material adverse effect on our financial condition, liquidity or results of operations.

8

Our business is dependent on construction activity. Downturns in construction activity could adversely affect our financial condition, liquidity or results of operations.

Our business has greater sales opportunities when construction activity is strong and, conversely, has fewer opportunities when such activity declines. The cyclical nature of commercial and residential construction activity, including construction activity funded by the public sector, tends to be influenced by prevailing economic conditions, including the rate of growth in GDP, prevailing interest rates, government spending patterns, business, investor and consumer confidence and other factors beyond our control. Prolonged downturns in construction activity could have a material adverse effect on our financial condition, liquidity or results of operations.

Risks Related to Liquidity

We require a significant amount of liquidity to fund our strategy and operations.

Our liquidity needs vary throughout the year. If our business experiences materially negative unforeseen events, we may be unable to generate sufficient cash flow from operations to fund our needs or maintain sufficient liquidity to operate and remain in compliance with our debt covenants, which could result in reduced or delayed planned capital expenditures and other investments and adversely affect our financial condition or results of operations.

Our credit agreements contain a number of covenants that impose significant operating and financial restrictions, including restrictions on our ability to engage in activities that may be in our best long-term interests.

The credit agreements underlying our $90 million Amended ABL Credit Facility and $70 million Term Loan Facility include covenants that, among other things, may impose significant operating and financial restrictions, including restrictions or limitations on our ability to engage in activities that may be in our best long-term interests. The credit facilities include covenants that, among other things, require us to provide the bank groups' agents (the “Agents”) with certain information with respect to us and the borrowing base and to maintain or otherwise preserve the collateral in favor of the Agents and further restricts our ability to make acquisitions and repurchase equity. Under the terms of the credit facilities, we are required to maintain a specified fixed charge coverage and net leverage ratios. Our ability to meet these ratios could be affected by events beyond our control and we cannot assure that we will meet them. A breach of any of the restrictive covenants or ratios would result in a default under the credit facilities. If any such default occurs, the lenders under the credit facilities may be able to elect to declare all outstanding borrowings under our facilities, together with accrued interest and other fees, to be immediately due and payable, or enforce their security interest. The lenders may also have the right in these circumstances to terminate commitments to provide further borrowings.

Our indebtedness may adversely affect our cash flow and our ability to operate our business, make payments on our indebtedness and declare dividends on our capital stock.

Our level of indebtedness and degree of leverage could:

•make it more difficult for us to satisfy our obligations with respect to our indebtedness;

•make us more vulnerable to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation;

•limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

•place us at a competitive disadvantage compared to our competitors that are less leveraged and, therefore, more able to take advantage of opportunities that our leverage prevents us from pursuing;

•limit our ability to refinance existing indebtedness or borrow additional amounts for working capital, capital expenditures, acquisitions, debt service requirements, execution of our business strategy or other purposes;

•restrict our ability to pay dividends on our capital stock; and

•adversely affect our credit ratings.

We may also incur additional indebtedness, which could exacerbate the risks described above. In addition, to the extent that our indebtedness bears interest at floating rates, our sensitivity to interest rate fluctuations will increase.

Any of the above listed factors could materially adversely affect our financial condition, liquidity or results of operations.

Risks Related to the Macro-Economic and Regulatory Environment

Our business, results of operations, financial condition, cash flows and stock price can be adversely affected by pandemics, epidemics or other public health emergencies, such as the outbreak of COVID-19.

We could be negatively impacted by the widespread outbreak of an illness or any other communicable disease, or any other public health crisis that results in economic and trade disruptions, including the disruption of global supply chains. In December 2019, there was an outbreak of a new strain of COVID-19. On March 11, 2020, the World Health Organization characterized COVID-19 as a pandemic. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and workforce participation due to “shelter-in-place” restrictions by various governments worldwide and created significant volatility and disruption of financial markets. This adversely impacted our results of operations during fiscal year 2020. The extent of the impact of the COVID-19 pandemic on our future operational and financial performance, including our ability to execute our business strategies and initiatives in the expected time frame, will depend on future developments, including the duration and spread of the pandemic and related restrictions on travel and transports; the effect on our customers and demand for our products and services; our ability to sell and provide our products and services, including as a result of travel restrictions and people working remotely; the ability of our customers to pay for our products and services; the overall health of our production employees and our ability to maintain adequate staffing of our facilities to satisfy marketplace demand for our products; and any closures of our or our customers’ offices and facilities all of which are uncertain and cannot be predicted. An extended period of global supply chain and economic disruption could materially affect our business, our results of operations, our access to sources of liquidity, the carrying value of our tangible and intangible assets, our financial condition and our stock price.

Worldwide economic conditions could have a material adverse impact on our financial condition, liquidity or results of operations.

Our business is influenced by conditions in domestic and foreign economies, including inflation, deflation, interest rates, availability and cost of capital, consumer spending rates, energy availability and the effects of governmental initiatives to manage economic conditions. Volatility in financial markets and the continued softness or further deterioration of national and global economic conditions could have a material adverse effect on our financial condition, liquidity or results of operations, including as follows:

•the financial stability of our customers or suppliers may be compromised, which could result in additional bad debts for us or non-performance by suppliers;

•commercial and residential consumers of our products may postpone spending in response to tighter credit, negative financial news and/or stagnation or further declines in income or asset values, which could have a material adverse impact on the demand for our product;

•the fair value of the investment funds underlying our defined-benefit pension plans may decline, which could result in negative plan investment performance, additional charges and may require significant cash contributions to such plans to meet obligations or regulatory requirements; and

•our asset impairment assessments and underlying valuation assumptions may change, which could result from changes to estimates of future sales and cash flows that may lead to substantial impairment charges.

Continued or sustained deterioration of economic conditions would likely exacerbate and prolong these adverse effects.

We are subject to risks associated with our international operations in both established and emerging markets. Legislative, political, regulatory and economic volatility, as well as vulnerability to infrastructure and labor disruptions, could have an adverse effect on our financial condition, liquidity or results of operations.

A portion of our products move in international trade, with approximately 20% of our revenues from operations outside the U.S. and Canada in 2020. Our international trade is subject to currency exchange fluctuations, trade regulations, tariffs, import duties, logistics costs, delays and other related risks, including, for example, the COVID-19 outbreak. Our international operations are also subject to various tax rates, credit risks in emerging markets, political risks, uncertain legal systems and loss of sales to local competitors following currency devaluations in countries where we import products for sale.

10

In addition, our international growth strategy depends in part on our ability to expand our operations in certain emerging markets. However, some emerging markets have greater political and economic volatility and greater vulnerability to infrastructure and labor disruptions than established markets. In many countries outside of the U.S., particularly in those with developing economies, it may be common for others to engage in business practices prohibited by laws and regulations applicable to us, such as the Foreign Corrupt Practices Act or similar local anti-corruption or anti-bribery laws, which generally prohibit companies and their employees, contractors or agents from making improper payments to government officials for the purpose of obtaining or retaining business. Failure to comply with these laws, as well as U.S. and foreign export and trading laws, could subject us to civil and criminal penalties. As we continue to expand our business globally, including in emerging markets, we may have difficulty anticipating and effectively managing these and other risks that our international operations may face, which may adversely affect our business outside the U.S. and our financial condition, liquidity or results of operations.

We may be subject to liability under and may make substantial future expenditures to comply with environmental laws and regulations, which could materially adversely affect our financial condition, liquidity or results of operations.

We are involved with environmental investigation and remediation activities for which our ultimate liability may exceed the currently estimated and accrued amounts. It is possible that we could become subject to additional environmental matters and corresponding liabilities in the future. See Note 19, Litigation and Related Matters, in Part II, Item 8, "Financial Statements," for further information related to environmental matters.

Our industry has been subject to claims relating to raw materials. We have not received any significant claims involving our raw materials or our product performance; however, product liability insurance coverage may not be available or adequate in all circumstances to cover claims that may arise in the future.

In addition, our operations are subject to various domestic and foreign environmental, health and safety laws and regulations. These laws and regulations not only govern our current operations and products, but also impose potential liability on us for our past operations. Our costs to comply with these laws and regulations may increase as these requirements become more stringent in the future and these increased costs may materially adversely affect our financial condition, liquidity or results of operations.

Other Risks Related to our Operations

Disruptions to or failures of our various information systems could have an adverse effect on our business.

We rely heavily on our information systems to operate our business activities, including, among other things, purchasing, distribution, inventory management, processing, shipping and receiving, billing and collection, financial reporting and record keeping. We also rely on our computer hardware, software and network for the storage, delivery and transmission of data to our sales systems, distribution systems and certain of our production processes are managed and conducted by computer. Any interruption, whether caused by human error, natural disasters, power loss, computer viruses, system conversion, intentional acts of vandalism, or various forms of cybercrimes including and not limited to hacking, intrusions, malware or otherwise, could disrupt our normal operations. There can be no assurance that we can effectively carry out our disaster recovery plan to handle the failure of our information systems, or that we will be able to restore our operational capacity within sufficient time to avoid material disruption to our business. The occurrence of any of these events could cause unanticipated disruptions in service, decreased customer service and customer satisfaction, harm to our reputation and loss or misappropriation of sensitive information, which could result in loss of customers, increased operating expenses and financial losses. Any such events could in turn have a material adverse effect on our financial condition, liquidity or results of operations.

Our performance depends on our ability to attract, develop and retain talented management.

We must attract, develop and retain qualified and talented personnel in senior management, sales, marketing, product design and operations. We compete with numerous companies for these employees and invest resources in recruiting, developing, motivating and retaining them. The failure to attract, develop, motivate and retain key employees could negatively affect our competitive position, execution on strategic priorities and operating results.

11

Our intellectual property rights may not provide meaningful commercial protection for our products or brands, which could adversely impact our financial condition, liquidity or results of operations.

We rely on our proprietary intellectual property, including numerous patents and registered trademarks, as well as our licensed intellectual property to market, promote and sell our products. We will monitor and protect against activities that might infringe, dilute, or otherwise harm our patents, trademarks and other intellectual property and rely on the patent, trademark and other laws of the U.S. and other countries. However, we may be unable to prevent third parties from using our intellectual property without our authorization. In addition, the laws of some non-U.S. jurisdictions, particularly those of certain emerging markets, will provide less protection for our proprietary rights than the laws of the U.S. and present greater risks of counterfeiting and other infringement. To the extent we cannot protect our intellectual property, unauthorized use and misuse of our intellectual property could harm our competitive position and have a material adverse effect on our financial condition, liquidity or results of operations.

Adverse judgments in regulatory actions, product claims, environmental claims and other litigation could be costly. Insurance coverage may not be available or adequate in all circumstances.

In the ordinary course of business, we are subject to various claims and litigation. Any such claims, whether with or without merit, could be time consuming and expensive to defend and could divert management’s attention and resources. While we will strive to ensure that our products comply with applicable government regulatory standards and internal requirements, and that our products perform effectively and safely, customers from time to time could claim that our products do not meet warranty or contractual requirements, or were improperly installed and users could claim to be harmed by use or misuse of our products. These claims could give rise to breach of contract, warranty or recall claims, or claims for negligence, product liability, strict liability, personal injury or property damage. They could also result in negative publicity.

In addition, claims and investigations may arise related to patent infringement, distributor relationships, commercial contracts, antitrust or competition law requirements, employment matters, employee benefits issues, data privacy and other compliance and regulatory matters, including anti-corruption and anti-bribery matters. For example, we are currently a party to various litigation matters that involve product liability, tort liability and other claims under a wide range of allegations, including illness due to exposure to certain chemicals used in the workplace, or medical conditions arising from exposure to product ingredients or the presence of trace contaminants. In some cases, these allegations involve multiple defendants and relate to legacy products that we and other defendants purportedly manufactured or sold. While we have processes and policies designed to mitigate these risks and to investigate and address such claims as they arise, we will not be able to predict or, in some cases, control the costs to defend or resolve such claims.

We currently maintain insurance against some, but not all, of these potential claims. In the future, we may not be able to maintain insurance at commercially acceptable premium levels. In addition, the levels of insurance we maintain may not be adequate to fully cover any and all losses or liabilities. If any significant judgment or claim is not fully insured or indemnified against, it could have a material adverse impact. We cannot assure that the outcome of all current or future litigation will not have a material adverse effect on our financial condition, liquidity or results of operations.

Increased costs of labor, labor disputes, work stoppages or union organizing activity could delay or impede production and could have a material adverse effect on our financial condition, liquidity or results of operations.

Increased costs of U.S. and international labor, including the costs of employee benefits plans, labor disputes, work stoppages or union organizing activity could delay or impede production and have a material adverse effect on our financial condition, liquidity or results of operations. A significant portion of our manufacturing employees are represented by unions and covered by collective bargaining or similar agreements, we often incur costs attributable to periodic renegotiation of those agreements, which may be difficult to project. We are also subject to the risk that strikes or other conflicts with organized personnel may arise or that we may become the subject of union organizing activity at our facilities that do not currently have union representation. Prolonged negotiations, conflicts or related activities could also lead to costly work stoppages and loss of productivity.

We outsource our information technology infrastructure which makes us more dependent upon third parties.

In an effort to make our information technology (“IT”) functions more efficient, increase related capabilities, as well as generate cost savings, we outsource a significant portion of our IT infrastructure to a third party service provider. As a result, we rely on the third party to ensure that our related needs are sufficiently met. This reliance subjects us to risks arising from the loss of control over certain processes, changes in pricing that may affect our operating results and potentially, termination of provisions of these services by our supplier. A failure of our service provider to perform may have a material adverse effect on our financial condition, liquidity or results of operations.

Risks Related to our Common Stock

Our stock price is subject to volatility.

Our stock price has experienced price volatility in the past and may continue to do so in the future. We, the flooring industry and the stock market have experienced stock price and volume fluctuations that have affected stock prices in ways that may have been unrelated to operating performance.

A stockholder's percentage of ownership in us may be diluted in the future.

A stockholder's percentage ownership in us may be diluted because of equity issuances for acquisitions, capital market transactions or otherwise, including, without limitation, equity awards that we may grant to our directors, officers and employees. Such issuances may have a dilutive effect on our earnings per share, which could adversely affect the market price of our common stock.

In addition, our amended and restated certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designation, powers, preferences and relative, participating, optional and other special rights, including preferences over our common stock with respect to dividends and distributions, as our Board of Directors (the "Board") generally may determine. The terms of one or more classes or series of preferred stock could dilute the voting power or reduce the value of our common stock. For example, we could grant the holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we could assign to holders of preferred stock could affect the residual value of our common stock.

Certain provisions in our amended and restated certificate of incorporation and bylaws, and of Delaware law, may prevent or delay an acquisition of our company, which could decrease the trading price of our common stock.

Our amended and restated certificate of incorporation and amended and restated bylaws contain, and Delaware law contains, provisions that are intended to deter coercive takeover practices and inadequate takeover bids by making such practices or bids unacceptably expensive to the bidder and to encourage prospective acquirers to negotiate with our Board rather than to attempt a hostile takeover. These provisions include, among others:

•the inability of our stockholders to call a special meeting;

•rules regarding how stockholders may present proposals or nominate directors for election at stockholder meetings;

•the right of our Board of directors to issue preferred stock without stockholder approval;

•a provision that directors serving on a classified board may be removed by stockholders only for cause; and

•the ability of our directors, and not stockholders, to fill vacancies on our Board.

In addition, because we are subject to Section 203 of the General Corporation Law of the State of Delaware (the “DGCL”), this provision could also delay or prevent a change in control that stockholders may favor. Section 203 provides that, subject to limited exceptions, persons that acquire, or are affiliated with a person that acquires, more than 15% of the outstanding voting stock of a Delaware corporation shall not engage in any business combination with that corporation, including by merger, consolidation or acquisitions of additional shares, for a three-year period following the date on which that person or its affiliates becomes the holder of more than 15% of the corporation’s outstanding voting stock.

We believe these provisions will protect our stockholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with our Board and by providing our Board with more time to assess any acquisition proposal. These provisions are not intended to make us immune from takeovers. However, these provisions will apply even if the offer may be considered beneficial by some stockholders and the provisions could delay or prevent an acquisition that our Board determines is not in the best interests of AFI and its stockholders. These provisions may also prevent or discourage attempts to remove and replace incumbent directors.

Risks Related to the Separation from AWI

If the Separation and Distribution fails to qualify as a tax-free transaction for U.S. federal income tax purposes, then we could be subject to significant tax liability or tax indemnity obligations.

AWI received an opinion of AWI’s tax counsel, Skadden, Arps, Slate, Meagher & Flom LLP, on the basis of certain facts, representations, covenants and assumptions set forth in such opinion, substantially to the effect that, for U.S. federal income tax purposes, the Separation and Distribution should qualify as a transaction that generally is tax-free to AWI and AWI’s shareholders, for U.S. federal income tax purposes, under Sections 355 and 368(a)(1)(D) of the Internal Revenue Code.

Notwithstanding the tax opinion, the Internal Revenue Service (“IRS”) could determine on audit that the Distribution should be treated as a taxable transaction if it determines that any of the facts, assumptions, representations or covenants set forth in the tax opinion is not correct or has been violated, or that the Distribution should be taxable for other reasons, including as a result of a significant change in stock or asset ownership after the Distribution, or if the IRS were to disagree with the conclusions of the tax opinion. If the Distribution is ultimately determined to be taxable, the Distribution could be treated as a taxable dividend to shareholders for U.S. federal income tax purposes and shareholders could incur significant U.S. federal income tax liability. In addition, AWI and/or we could incur significant U.S. federal income tax liabilities or tax indemnification obligations, whether under applicable law or the Tax Matters Agreement that we entered into with AWI, if it is ultimately determined that certain related transactions undertaken in anticipation of the Distribution are taxable.

We will be required to satisfy certain indemnification obligations to AWI or may not be able to collect on indemnification rights from AWI.

Under the terms of the Separation and Distribution, we will indemnify AWI from and after the Separation and Distribution with respect to (i) all debts, liabilities and obligations allocated or transferred to us in connection with the Separation and Distribution (including our failure to pay, perform or otherwise promptly discharge any such debts, liabilities or obligations after the Separation and Distribution); (ii) any misstatement or omission of a material fact in our Information Statement, dated March 24, 2016, resulting in a misleading statement; (iii) any breach by us of the Separation and Distribution Agreement, the Employee Matters Agreement, the Tax Matters Agreement, the Campus Lease Agreement or the Trademark License Agreements; and (iv) our ownership and operation of our business. We are not aware of any existing indemnification obligations at this time, but any such indemnification obligations that may arise could be significant. Under the terms of the Separation and Distribution Agreement, AWI will indemnify us from and after the Separation and Distribution with respect to (i) all debts, liabilities and obligations allocated to AWI after the Separation and Distribution (including its failure to pay, perform or otherwise promptly discharge any such debts, liabilities or obligations after the Separation and Distribution); (ii) any breach by AWI of the Separation and Distribution Agreement, the Employee Matters Agreement, the Tax Matters Agreement, the Campus Lease Agreement or the Trademark License Agreements; and (iii) AWI’s ownership and operation of its business. Our and AWI’s ability to satisfy these indemnities, if called upon to do so, will depend upon our and AWI’s future financial strength. If we are required to indemnify AWI, or if we are not able to collect on indemnification rights from AWI, our financial condition, liquidity or results of operations could be materially and adversely affected. We cannot determine whether we will have to indemnify AWI, or if AWI will have to indemnify us, for any substantial obligations after the Distribution.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

Armstrong Flooring, Inc. ("AFI" or the "Company") is a leading global producer of flooring products for use primarily in the construction and renovation of commercial, residential and institutional buildings. We design, manufacture, source and sell resilient flooring products primarily in North America and the Pacific Rim. As of December 31, 2020, we operated 8 manufacturing plants in three countries, including 6 manufacturing plants located throughout the U.S. (California, Illinois, Mississippi, Oklahoma and Pennsylvania) and one plant each in China and Australia. When we refer to "we," "our," and "us" in this report, we are referring to Armstrong Flooring, Inc. and its consolidated subsidiaries.

During early 2020, the Company established a multi-year strategic roadmap to transform and modernize its operations to become a leaner, faster-growing and more profitable business. The transformation encompasses three critical objectives: (i) expanding customer reach; (ii) simplifying product offerings and operations; and (iii) strengthening core capabilities. In addition, the Company has implemented a new operating model to more effectively accomplish these objectives by: (i) placing customers first by aligning services and products through a more seamless value chain; (ii) leading the industry in product innovation; (iii) simplifying processes and operating complexity to become more competitive and efficient; (iv) realigning the go-to-market model to reach all relevant channels and customers; (v) implementing system changes to improve operations, reduce costs and reignite organic growth; and (vi) investing thoughtfully with a return-focused mindset. The goal of this focused strategy is to transform and modernize AFI, resulting in a company that is more agile, faster-growing and more profitable.

To date, the Company has (i) announced the phased relocation of its corporate headquarters, effective spring and summer 2021, with estimated cost savings of approximately 60% annually; (ii) began consolidating U.S. manufacturing facilities with the intent to monetize non-core assets; (iii) executed product portfolio simplification and inventory optimization initiatives; (iv) commenced manufacturing projects aimed at improving efficiency; (v) begun to focus on enhancing customer experiences through new methods of customer interactions and communication as well as the introduction of a quick-ship program; (vi) invested in product innovations with a focus on U.S.-based manufacturing; (vii) made significant investments in both talent and process improvement; (viii) made improvements in both plant and asset performance; (ix) started to service specific groups of customers on a direct basis; and (x) commenced rebranding initiatives, including introduction of a new logo in late 2020, to be further rolled out during 2021. The Company has incurred approximately $16 million in incremental costs associated with the above business transformation initiatives during 2020.

In June 2020, the Company amended its senior secured asset-based revolving credit facility, modifying the facility size to $90 million with a maturity date in 2023. Additionally, to further strengthen its capital resources for business transformation and growth initiatives, the Company entered into a $70 million term loan facility maturing in 2025. The Company capitalized $7.4 million of fees related to the new term loan facility, all of which had been paid at December 31, 2020. The deferred financing costs will be amortized through 2025 over the life of the term loan facility. Refer to Liquidity and Capital Resources for additional information related to amended credit facility and new term loan facility.

In November 2020, the Company reached a settlement in principle to fully resolve a putative class-action shareholder complaint. The agreement, which is subject to final documentation and Court approval, provides in part for a settlement payment of $3.75 million in exchange for the dismissal and a release of all claims against the defendants in connection with the securities class action suit. either the Company nor any individual defendant admits any wrongdoing through the settlement agreement. The $3.75 million settlement payment will be paid by the Company’s insurance provider under its insurance policy. Payment is expected during 2021.

In December 2020, we formally announced the closure of its South Gate, California facility which is expected to be completed during the first quarter of 2021. In connection with this closure, we recognized charges of approximately $6 million, during the fourth quarter of 2020, related to long-lived assets, including the write-off of related spare parts and anticipated contract termination fees. In addition, the Company anticipates future cash expenditures related to previously accrued severance and employee termination costs of less than $1 million. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

Management's Discussion and Analysis of Financial Condition and Results of Operations

COVID-19

The COVID-19 pandemic is significantly impacting our business and results of operations. We are committed to safeguarding our employees and the communities in which we operate, while continuing to deliver our products to customers. We are following guidelines and directives from governmental authorities and local health authorities across our facilities to continue to operate safely and responsibly. This includes working remotely, providing personal protective equipment, limiting group meetings, restricting air travel, enhancing cleaning / sanitization procedures and practicing social distancing, among other risk mitigation measures.

Our China plant was closed most of the month of February 2020. On April 1, 2020, we announced a proactive two-week production suspension in our North America plants beginning April 5, 2020 in response to the increasing social and economic impact of COVID-19. We reopened our North America plants as planned following the two-week shut-down. Our plants continued their operations during the remainder of 2020. Additionally, in August 2020 the Company's Australia plant began to operate at approximately 60% capacity due to additional governmental restrictions which have now ceased. We have not experienced, and do not anticipate, material availability issues related to our raw materials or finished goods. However, during the fourth quarter of 2020 we started to see the impact of the imbalance of global shipping capacity and demand lead to delays in receipt of goods from China and Vietnam at U.S. ports.

To help mitigate the potential spread of the virus, our North America sales team and corporate staff are working remotely and will continue to do so indefinitely. In the second quarter we furloughed approximately 100 employees, primarily administrative staff from our corporate headquarters. Most of the furloughed employees returned in July 2020. In addition, the employer match for certain benefit plans was suspended from May 2020 through the end of the third quarter of 2020 for salaried non-production employees. The employer match was reinstated on October 1, 2020.

Inconsistent state and local government orders resulted in varying impacts to our results across geographies and for some of our customers. Generally, home centers have continued to operate. Construction is considered an essential business in most of North America. However, some of our customers' commercial projects in the retail, office, medical and educational sectors have been postponed. These factors have led to a softer demand environment in certain states and channels.

The ultimate duration and impact of the pandemic on our future results is unknown.

Outlook

Looking forward, the Company remains committed to profitable growth over the medium and long-term; however, results will continue to be negatively impacted by COVID-19 into 2021, primarily in the commercial markets served by the Company as well as costs associated with Company's on-going business transformation initiatives. The Company's view for 2021 is supported by the below factors, which should be considered in the context of other risks, trends and strategies described in this Annual Report on Form 10-K:

•The Company expects sales to improve during full year 2021 compared to 2020 as a result of decreased COVID-19 pressures, the impact of recently announced price increases, continued expansion into additional market segments, positive trends in residential end markets and new product introductions.

•Operating results in the short-term will be negatively impacted by incremental expenses necessary to execute the Company's business transformation initiatives. Funding for these initiatives will be aided by the deployment of capital associated with the anticipated sale of our South Gate, California facility in 2021. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

•As the Company navigates 2021, it is focused on several uncertainties, which may impact operating results, including navigating the continued impact of COVID-19, inflationary pressures and the economy-wide logistic and shipping challenges related to receiving goods from China.

•As the Company continues to execute against its multi-year strategic roadmap, the primary areas of focus for 2021 will include: (i) continued focus on improving the customer experience while also improving overall profitability; (ii) continued introduction of compelling products into the markets we serve; (iii) expansion of existing and entry into new market segments; and (iv) completion of our headquarters and technology center during the spring and summer of 2021.

Net Sales

Net sales by percentage point change are shown in the tables below:

	Year Ended December 31,				Change				Percentage Point Change Due to
(Dollars in millions)	2020		2019		$		%		Price		Volume		Mix		Currency
	$	584.8	$	626.3	$	(41.5)	(6.6)	%	(1.5)	%	(6.0)	%	1.0	%	(0.1)	%

	$	626.3	$	728.2	$	(101.9)	(14.0)	%	(0.1)	%	(9.8)	%	(3.2)	%	(0.9)	%

Net sales for the year ended December 31, 2020 decreased $41.5 and 6.6% compared to the year ended December 31, 2019 primarily due to lower sales volume due to COVID-19 pandemic related business disruptions, including the postponement of certain commercial projects and slower activity at many independent customer retail locations.

Net sales for the year ended December 31, 2019 decreased $101.9 million and 14.0% compared to the year ended December 31, 2018 primarily due to lower sales volume. Lower sales volume reflected relative changes in distributor inventory levels compared to the prior year due to significant customer purchases in the distribution channel in 2018 ahead of U.S. tariffs and decline in traditional categories. Volume was also lower due to share loss in some categories within the distribution channel. Unfavorable mix was driven by lower relative luxury vinyl tile sales, which was impacted by the aforementioned higher distributor sales in 2018 ahead of tariff increases.

Cost of goods sold

Cost of goods sold for the year ended December 31, 2020 was 85.7% of net sales compared to 86.4% of net sales for year-ending December 31, 2019. The decrease in percent was primarily due to a $13.6 million inventory write-down related to an inventory optimization initiative that occurred during 2019 and did not repeat during 2020, partially offset by inefficiencies caused by decreases in volume and non-recurring costs associated with the consolidation of our manufacturing activities as part of the Company's business transformation initiatives during 2020.

19

Management's Discussion and Analysis of Financial Condition and Results of Operations

Cost of goods sold for the year ended December 31, 2019 was 86.4% of net sales compared to 80.3% of net sales for year-ending December 31, 2018. The increase in percent was primarily due to the $13.6 million inventory write-down related to an inventory optimization initiative during 2019 and inefficiencies caused by decrease in volume.

Selling, general & administrative expenses

Selling, general and administrative expenses for the year-ended December 31, 2020 decreased $1.2 million and 0.8% compared to the year-ended December 31, 2019. The decrease in 2020 is driven by a reduction in core selling, general and administrative resulting from business transformation initiatives as well as $14.2 million of expenses incurred during 2019 related to a samples inventory write-down, strategic initiative costs and employee termination costs that did not repeat during 2020, partially offset by $19.0 million of non-recurring transition services income from TZI that did not repeat in 2020.

Selling, general and administrative expenses for the year-ended December 31, 2019 decreased $14.2 million and 8.8% compared to the year-ended December 31, 2018. Results for 2019 were positively impacted by receipt of the transition services income from TZI noted above, partially offset by higher strategic initiative and employee termination costs during 2018 compared to 2019.

Business transformation costs

Beginning in 2018, the Company commenced a multi-year business transformation which resulted in a strategic roadmap formally announced during 2020. The multi-year roadmap encompasses three critical objectives: (i) expanding customer reach; (ii) simplifying product offerings and operations; and (iii) strengthening core capabilities. Such costs are included in the captions Costs of goods sold and Selling, general and administrative expenses on the Company's Consolidated Statements of Operations as required by U.S. generally accepted accounting principles ("U.S. GAAP"). A summary of business transformation costs included in these captions for the periods presented include:

	For the Years Ended December 31,
	2020				2019				2018
	Cost of Goods Sold		Selling, General & Administrative Expenses		Cost of Goods Sold		Selling, General & Administrative Expenses		Cost of Goods Sold		Selling, General & Administrative Expenses
Site exit costs	$	5.7	$	0.8	$	4.6	$	—	$	—	$	—
Strategic initiative costs	—		0.9		—		5.4		—		6.6

Net gains	—		(0.2)		—		—		—		—
Total	$	5.7	$	2.2	$	18.2	$	14.3	$	—	$	12.1

Site exit costs - Site exit costs include costs associated with exit or disposal activities, including asset write-downs. Costs in both 2020 and 2019 relate primarily to the Company's South Gate, California facility which is classified as Assets held-for-sale as of December 31, 2020 on the Consolidated Balance Sheets. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

Strategic initiative costs - Costs of non-recurring strategic projects, including executive leadership transitions, that are not considered part of normal operations. Costs incurred in 2020 related to non-severance costs related to the CFO transition. Costs in 2019 related to non-severance costs related to the CEO transition, the sale of the wood business and development of strategy alternatives. Costs in 2018 related to the sale of the wood business and development of strategy alternatives.

Employee termination costs - Costs of involuntary termination benefits associated with one-time benefit arrangements provided as part of an exit or disposal activity are recognized by the Company when a formal plan for reorganization is approved at the appropriate level of management and communicated to affected employees. The employee termination benefit costs in 2020 and 2019 related to our former CFO and former CEO, respectively. The employee termination benefit costs in 2018 related to the divestiture of our North American wood flooring business.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Product rationalization - On September 11, 2019, Michel S. Vermette was appointed Chief Executive Officer of the Company and initiated the implementation of a new multi-year product strategy and inventory optimization plan, which includes focusing on critical products and standardizing procedures to enable better decision making. As a result, we recorded a non-cash inventory write down of $13.6 million during the third quarter of 2019, primarily related to the write down of inventory in certain product categories to estimated liquidation value. Directly related to this strategy and inventory optimization plan, merchandising materials of $6.0 million were written off as obsolete in the third quarter of 2019 in connection with a decreased demand for residential displays following our go to market change.

Net gains - Net gains result from the sale of redundant properties (primarily land and buildings) and non-core assets. In 2020 net gains related to the sale of a property in Vicksburg, Mississippi that had been classified as Assets held-for-sale during 2020. The property was originally retained as part of the sale of the wood business in 2018.

Interest expense

For the year-ended December 31, 2020, interest expense increased $3.1 million and 70.5% compared to year-ended December 31, 2019 due to higher interest rates on debt outstanding resulting from our June 2020 refinancing.

For the year-ended December 31, 2019, interest expense decreased $0.4 million and 8.3% compared to year-ended December 31, 2018 due to lower average debt outstanding.

Other (income) expense, net

Other (income) expense, net of $(4.8) million, $1.8 million and $2.9 million for the years ended December 31, 2020, 2019 and 2018, respectively, primarily reflected benefit from changes to or costs related to defined-benefit pension and postretirement plans. Changes in actuarial assumptions relating to current year expense and a non-recurring postretirement gain resulting from a plan change totaling $1.8 million, resulted in income during 2020.

Income tax expense (benefit)

For the year ended December 31, 2020 we recorded an income tax benefit of $0.8 million compared to an income tax expense of $1.6 million for the year ended December 31, 2019. The effective tax rates were a benefit of 1.2% and an expense of 2.4% for the years ended December 31, 2020 and 2019, respectively.

For the year ended December 31, 2019 we recorded an income tax expense of $1.6 million compared to an income tax benefit of $6.0 million for the year ended December 31, 2018. The effective tax rates were a benefit of 2.4% and an expense of 23.9% for the years ended December 31, 2019 and 2018, respectively.

The change in effective rates during both periods was primarily driven by changes in the mix of income among tax jurisdictions and the impact of discontinued operations, as well as the effects of non-benefited losses.

Discontinued operations

For the year ended December 31, 2020 there was no discontinued operations activity. For the year ended December 31, 2019, a $10.4 million gain on disposal of discontinued operations was realized primarily due to the resolution of our antidumping case. For the year ended December 31, 2018, loss on disposal of discontinued operations of $153.8 million related to our sale of the North American wood flooring business. This loss was partially offset by $9.9 million of earnings from discontinued operations while reflecting the operating results of the North American wood flooring business prior to the sale. See Note 7, Discontinued Operations, in Part II, Item 8, "Financial Statements" of the consolidated financial statements.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Liquidity and Capital Resources

During the second quarter of 2020, the Company entered into a Third Amendment (the "Amendment") to the ABL Credit Facility (the "Amended ABL Credit Facility") and entered into a new term loan facility with Pathlight Capital L.P. (the "Term Loan Agent") as the administrative agent ("Term Loan Agreement") which provides us with a secured term loan credit facility of $70 million (the “Term Loan Facility”). We used the proceeds of the Term Loan Facility to pay down the Amended ABL Credit Facility.

Amended ABL Credit Facility

On June 23, 2020, we entered into the Amended ABL Credit Facility, which reduces commitments from $100 million to $90 million, amends the interest rates applicable to the borrowings, modifies certain financial maintenance and other covenants, as well as permits indebtedness under the Term Loan Agreement. The Amended ABL Credit Facility provides for a borrowing base that is derived from our accounts receivable and inventory, collectively, with the equity interests in the guarantors, (the "ABL Priority Collateral"), subject to certain reserves and other limitations. The Amended ABL Credit Facility matures in December 2023.

The Amendment permits us to grant a first priority security interest in real estate, machinery and equipment and intellectual property collateral to the Term Loan Agent (collectively, the “Term Loan Priority Collateral”). Bank of America, N.A., as administrative agent and collateral agent (in such capacities, the “ABL Agent”) will not have a security interest in the real property securing the Term Loan Agreement (as defined below) but will have a second priority security interest in machinery and equipment and intellectual property constituting Term Loan Priority Collateral.

Borrowings under the Amended ABL Credit Facility bear interest at a rate per annum equal to, at our option, a base rate or a Eurodollar rate equal to the London interbank offered rate (“LIBOR”) for the relevant interest period, plus, in each case, an applicable margin determined in accordance with the provisions of the Amendment. The base rate will be the highest of (a) the federal funds rate plus 0.50%, (b) the prime rate of Bank of America, N.A. and (c) LIBOR plus 1.00%. The applicable margin for borrowings under the Amended ABL Credit Facility will be determined based on the Company’s Consolidated Leverage Ratio (as defined in the Amendment) and will range from 1.75% to 3.00% with respect to base rate borrowings and 2.75% to 4.00% with respect to Eurodollar rate borrowings. In addition to paying interest on outstanding principal under the Amended ABL Credit Facility, we will pay a commitment fee to the lenders with respect to the unutilized revolving commitments thereunder at a rate ranging from 0.375% to 0.50% depending on the Company’s Consolidated Leverage Ratio. The Amended ABL Credit Facility contains provisions to allow for the transition from LIBOR to the agreed upon successor rate.

All obligations under the Amended ABL Credit Facility are guaranteed by each of our wholly owned domestic subsidiaries that individually, or together with its subsidiaries, has assets of more than $1.0 million. All obligations under the Amended ABL Credit Facility, and guarantees of those obligations, are secured by all of the present and future assets of the Company and the guarantors, subject to certain exceptions and exclusions as set forth in the Amended ABL Credit Facility and other security and collateral documents.

During the fourth quarter of 2020 there was a reduction in available liquidity under the Amended ABL Credit Facility of $30 million until such time as the Company is able to sell our South Gate, California facility. This reduction was in effect at December 31, 2020. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

Term Loan Facility

On June 23, 2020 we also entered into the Term Loan Agreement which provides us with a secured term loan credit facility of $70 million. The borrowing base is derived from the Company’s machinery and equipment, intellectual property and real property, subject to certain reserves and other limitations. The Term Loan Facility is scheduled to mature on June 23, 2025. The principal balance of the Term Loan Facility is payable in quarterly installments beginning in June 2021.

Borrowings under the Term Loan Facility will bear interest at a rate per annum equal to LIBOR for a three-month interest period, plus an applicable margin of 12.00%. The Term Loan Facility contains provisions to allow for the transition from LIBOR to the agreed upon successor rate.

22

Management's Discussion and Analysis of Financial Condition and Results of Operations

We must use cash proceeds from certain dispositions, including sales of real estate, equity and debt issuances and extraordinary events to prepay outstanding loans under the Term Loan Facility, subject to specified exceptions, including the prepayment requirements with respect to the Amended ABL Credit Facility. Prepayments of loans under the Term Loan Facility prior to the third anniversary of the closing date are subject to certain premiums. The sale of our South Gate, California facility is anticipated during the first half of 2021 and would result in an estimated mandatory repayment of approximately $20 million. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

All obligations under the Term Loan Agreement are guaranteed by each of our wholly owned domestic subsidiaries that individually, or together with its subsidiaries, has assets of more than $1.0 million and are secured by a first priority lien on the Term Priority Collateral and a second priority lien on the ABL Priority Collateral.

In addition, the Term Loan Agreement requires us to comply with the Amended ABL Credit Facility financial covenants. The Term Loan Agreement also contains customary affirmative covenants and events of default, including a cross-default provision in respect of certain material indebtedness and a change of control provision. If an event of default occurs, the lenders may choose to accelerate the maturity of the Term Loan Facility and require repayment of all obligations thereunder.

The Company capitalized $7.4 million of fees related to the Term Loan Facility, which will be amortized through 2025 over the life of the Term Loan Facility.

See Note 14, Debt, in Part II, Item 8, "Financial Statements" to the Consolidated Financial Statements for additional information related to the Amended ABL Credit Facility and Term Loan Facility.

Cash Flows

The discussion that follows includes cash flows related to discontinued operations. The table below shows our cash (used for) provided by operating, investing and financing activities:

	Year Ended December 31,
(Dollars in millions)	2020		2019		2018
Cash (used for) provided by operating activities	$	(28.2)	$	(6.0)	$	62.5
Cash (used for) provided by investing activities	(21.1)		(29.4)		60.6
Cash provided by (used for) financing activities	35.0		(111.1)		13.3

Operating activities

Net cash used for operating activities for 2020 was $28.2 million, an increase of $22.2 compared to 2019. The primary drivers of this increase were lower net cash income and net increases in working capital, primarily inventory, other assets and liabilities and receivables, partially offset by accounts payable and accrued expenses.

Net cash used for operating activities for 2019 was $6.0 million, a decrease of $68.6 million from cash provided by operating activities in 2018. The primary drivers of this decrease were lower net cash income and changes in working capital, primarily accounts payable and accrued expenses, partially offset by inventory.

Investing activities

Net cash used for investing activities for 2020 was $21.1 million, a decrease of $8.3 million compared to 2019. The primary drivers for this decrease were lower purchases of property, plant and equipment and a cash payment related to discontinued operation in 2019 that did not repeat in 2020.

Net cash used for investing activities for 2019 was $29.4 million, a decrease of $90.0 million from cash provided by investing activities in 2018. The primary driver for this decrease was proceeds from the sale of the wood flooring business in 2018 which did not repeat during 2019.

Financing activities

Net cash provided by financing activities for 2020 was $35.0 million, an increase of $146.1 million from cash used by financing activities in 2019. The primary driver of this change was the net impact of the Company's debt refinancing during the second quarter of 2020.

23

Management's Discussion and Analysis of Financial Condition and Results of Operations

Net cash used for financing activities for 2019 was $111.1 million, a decrease of $124.4 from cash provided by financing activities in 2018. The primary drivers of this changes were increased purchases of treasury stock and higher net debt repayments during 2019.

Sources and Uses of Cash

Our primary sources of liquidity are, and we anticipate that they will continue to be, cash generated from operations, proceeds from asset sales and borrowings under our credit facilities. We believe these sources are sufficient to fund our capital needs, including the costs of our business transformation initiatives, planned capital expenditures and to meet our interest and other contractual obligations in the near term. Our liquidity needs for operations vary throughout the year with the majority of our cash flows generated in the second and third quarters.

As of December 31, 2020 there were borrowings of $10.0 million outstanding under our Amended ABL Credit Facility, while outstanding letters of credit were $5.4 million. Total net availability under the Amended ABL Credit Facility and Term Loan Facility as of December 31, 2020 was $34.3 million. During the fourth quarter, there was a reduction in available liquidity of $30.0 million until such time as we sell our South Gate, California facility. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

We are required to pay a commitment fee, payable quarterly in arrears, on the average daily unused amount of the revolving Amended ABL Credit Facility, which varies according to the net leverage ratio and was 0.50% as of December 31, 2020. Outstanding letters of credit issued under the Amended ABL Credit Facility are subject to fees which will be due quarterly in arrears based on the applicable margin described above plus a fronting fee. The total rate for letters of credit was 4.125% as of December 31, 2020.

Our foreign subsidiaries had available lines of credit totaling $9.2 million and there were $4.5 million borrowings under these lines of credit as of December 31, 2020. Total availability under these foreign lines of credit as of December 31, 2020 was $4.7 million.

In addition, the Company had $13.7 million of Cash and cash equivalents at December 31, 2020.

Based on the foregoing, the Company had total liquidity (including Cash and cash equivalents) of $52.7 million at December 31, 2020 compared to $89.6 million at December 31, 2019.

Debt Covenants

The Amended ABL Credit Facility requires, among other things, that we maintain a minimum Consolidated Cash Flow (as defined in the Amendment) for the three-fiscal quarter period ending September 30, 2020 and for any four-fiscal quarter period ending thereafter and during a Financial Covenant Trigger Period (as defined in the Amendment), maintain a minimum Consolidated Fixed Charge Coverage Ratio (as defined in the Amendment) of at least 1.00 to 1.00 (such covenants, the “Financial Covenants”).

The Term Loan Agreement contains a number of covenants that, among other things and subject to certain exceptions, restrict our ability to create liens, to undertake fundamental changes, to incur debt, to sell or dispose of assets, to make investments, to make restricted payments such as dividends, distributions or equity repurchases, to change the nature of our businesses, to enter into transactions with affiliates and to enter into certain burdensome agreements.

At December 31, 2020, we were in compliance with all debt covenants.

Cash Management

The Company has various cash management systems throughout the world that centralize cash in various bank accounts where it is economically justifiable and legally permissible to do so. These centralized cash balances are then redeployed to other operations to reduce short-term borrowings and to finance working capital needs or capital expenditures. Due to the transitory nature of cash balances, they are normally invested in bank deposits that can be withdrawn at will or in very liquid short-term bank time deposits. The Company's policy is to primarily use the banks that participate in our ABL credit facility located in the various countries in which the Company operates. The Company monitors the creditworthiness of banks and when appropriate will adjust banking operations to reduce or eliminate exposure to less creditworthy banks.

24

Management's Discussion and Analysis of Financial Condition and Results of Operations

At December 31, 2020, our Cash and cash equivalents totaled $13.7 million, of which $0.7 million was held in the U.S. and $13.0 million held by non-U.S. subsidiaries. At December 31, 2020 none of our consolidated cash and cash equivalents had regulatory restrictions that would preclude the transfer of funds with and among subsidiaries. While our remaining non-U.S. cash and cash equivalents can be transferred with and among subsidiaries, the majority of these non-U.S. cash balances will be used to support the ongoing working capital needs and continued growth of our non-U.S. operations.

Unconditional Purchase Obligations

Unconditional purchase obligations include purchase contracts whereby we must make guaranteed minimum payments of a specified amount regardless of how little material is actually purchased and service agreements. Unconditional purchase obligations exclude contracts entered into during the normal course of business that are non-cancelable and have fixed per unit fees, but where the monthly commitment varies based on usage. Our unconditional purchase obligations are mainly comprised of utility contracts and information technology service agreements. At December 31, 2020 these obligations totaled $38.5 million, of which $16.8 million is due in 2021, $7.3 million is due in 2022, $7.3 million is due in 2023 and $7.1 million is due in 2024.

In addition, we had $5.8 million of inventory in transit at December 31, 2020, where the title had not been passed to us; however, we are committed to make payment once these shipments reach the destination as required per the contract.

Critical Accounting Estimates

The Company's discussion and analysis of our financial condition and results of operations are based upon the Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, we evaluate the estimates, including those related to inventories, impairments of tangible and intangible assets, U.S. pension and other postretirement benefit costs and sales-related accruals. The impact of changes in these estimates, as necessary, is reflected in the results of operations in the period of the change. We base estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different outcomes, assumptions or conditions.

We believe the following critical accounting policies are affected by our more significant judgments and estimates used in the preparation of the Consolidated Financial Statements. Management has discussed the development and selection of the critical account estimates described below with the Audit Committee of the Board of Directors and they have reviewed our disclosures relating to these estimates in this Management's Discussion and Analysis of Financial Condition. These items should be read in conjunction with Note 2, Summary of Significant Accounting Policies, in Part II, Item 8, "Financial Statements."

Inventories

At December 31, 2020 and 2019 inventories of $122.9 million and $111.6 million, respectively, are net of reserves of $12.2 million and $11.3 million, respectively.

Critical Estimate - Inventories

U.S. inventories are valued at the lower of cost or market and cost is determined using the last-in, first-out ("LIFO") method of accounting. Non-U.S. inventories are valued at the lower of cost or net realizable value and cost is determined using the first-in, first-out method of accounting. Additionally, inventory balances are adjusted for estimated obsolete or unmarketable inventory equal to the difference between the cost of inventory and net realizable value or estimated market value, as applicable.

The Company records reserves to adjust its U.S. inventory balances to the LIFO method of inventory valuation. In adjusting these reserves throughout the year, the Company estimates its year-end inventory costs and quantities. At December 31 of each year, the reserves are adjusted to reflect actual year-end inventory costs and quantities. Changes in LIFO reserves resulted in pre-tax expense of $5.2 million, $4.7 million and $3.0 million during 2020, 2019 and 2018, respectively.

25

Management's Discussion and Analysis of Financial Condition and Results of Operations

We estimate our reserves for inventory obsolescence by continuously examining our inventories to determine if there are indicators that carrying values may exceed net realizable value or estimated market value. In assessing the realization of inventory balances, the Company is required to make significant judgements related to estimated future demand for products, estimated future selling prices and the amount of excess inventory on-hand. In addition, the Company takes into account other factors including the age of inventory on-hand and the ultimate sales prices recognized for previously dropped products. While we believe that adequate reserves for inventory obsolescence have been made in the Consolidated Financial Statements, consumer tastes and preferences as well as macroeconomic factors will continue to change and we could experience additional inventory write-downs in the future. It is estimated that a 10% change in our assumptions for excess or obsolete inventory would have affected net earnings by approximately $0.7 million for the year ended December 31, 2020.

The Company has not materially changed the methodology for calculating inventory reserves for the years presented. See Note 10, Inventories, in Part II, Item 8, "Financial Statements," for additional information.

Impairments of Tangible and Intangible Assets

At December 31, 2020 and 2019 Property, plant and equipment of $246.9 million and $277.2 million, respectively, are net of accumulated depreciation of $336.7 million and $318.4 million, respectively. At December 31, 2020 and 2019 intangible assets of $19.0 million and $25.4 million, respectively, are net of accumulated amortization of $26.1 million and $19.0 million, respectively.

Critical Estimate - Impairments of Tangible and Intangible Assets

We review long-lived asset groups, which include long-lived tangible and intangible assets, for impairment when indicators of impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by the asset indicates impairment, the asset is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.

The revenue and cash flow estimates used in applying our impairment and recoverability tests are based on management’s analysis of information available at the time of the impairment test. Actual results lower than the estimate could lead to significant future impairments. If future testing indicates that fair values have declined below carrying value, our financial condition and results of operations would be affected.

The potential impact of the COVID-19 pandemic, our recurring losses and our negative cash flows resulted in the identification of a triggering event requiring impairment testing of our North American asset group in the first quarter of 2020. Our test for recoverability, which utilized a probability-weighted income approach, compared the carrying value of the asset group to the sum of (i) the undiscounted cash flows expected to result from the use of the North American asset group; and (ii) the value of the North American asset group upon its eventual disposition. The results of this testing indicated that, as of March 31, 2020, our North American asset group was not impaired. There were no other triggering events during 2020.

During 2020 and 2019, we recognized $4.9 million and $4.6 million, respectively, of accelerated depreciation, primarily related to the intended closure of our South Gate, California manufacturing facility. There were no material long-lived asset or intangible asset impairment charges in 2018.

We cannot predict the occurrence of certain events that might lead to material impairment charges in the future. Such events may include, but are not limited to, the impact of economic environments, particularly related to the commercial and residential construction industries, material adverse changes in relationships with significant customers, or strategic decisions made in response to economic and competitive conditions.

The Company has not materially changed the methodology for calculating intangible impairments for the years presented. See Note 11, Property, Plant and Equipment; and Note 12, Intangible Assets, in Part II, Item 8, "Financial Statements," for additional information.

Management's Discussion and Analysis of Financial Condition and Results of Operations

U.S. Pension and Postretirement Benefit Costs

At December 31, 2020 and 2019, the Company had combined pension and postretirement liabilities of $63.1 million and $81.3 million, respectively. During the years-end December 31, 2020, 2019 and 2018, we incurred U.S. pension and postretirement benefit costs of $1.1 million, $5.6 million and $7.4 million, respectively. In addition, as a result of the elimination of future life insurance benefits for certain employees, we recorded a curtailment gain of $1.8 million in 2020 in other income.

Critical Estimate - U.S. Pension and Postretirement Benefit Costs

We maintain pension and postretirement plans throughout North America, with the most significant plans located in the U.S. Our defined-benefit pension and postretirement benefit costs are developed from actuarial valuations. These valuations are calculated using a number of assumptions, which represent management’s best estimate of the future assumptions. The assumptions that have the most significant impact on reported results are the discount rate, the estimated long-term return on plan assets, mortality rates and anticipated inflation in health care costs. These assumptions are generally updated annually.

The discount rate is used to determine retirement plan liabilities and to determine the interest cost component of net periodic pension and postretirement cost. Management utilizes the Aon Hewitt AA Only Above Median yield curve, which is a hypothetical AA yield curve comprised of a series of annualized individual discount rates, as the primary basis for determining the discount rate. As of December 31, 2020, we assumed a discount rate of 2.50% for the U.S. defined-benefit pension plans and a discount rate of 2.45% for the U.S. postretirement plans. As of December 31, 2019, we assumed a discount rate of 3.25% for the U.S. defined-benefit pension plans and a discount rate of 3.20% for the U.S. postretirement plans. The effects of any change in discount rate will be amortized into earnings as described below. Absent any other changes, a one-quarter percentage point increase or decrease in the discount rates for the U.S. pension and postretirement plans would be expected to decrease or increase 2021 operating income by approximately $0.2 million.

We manage two U.S. defined-benefit pension plans, a qualified funded plan and a nonqualified unfunded plan. For the qualified funded plan, the expected long-term return on plan assets represents a long-term view of the future estimated investment return on plan assets. This estimate is determined based on the target allocation of plan assets among asset classes and input from investment professionals on the expected performance of the asset classes over 20 years. Historical asset returns are monitored and considered when we develop our expected long-term return on plan assets. An incremental component is added for the expected return from active management based on historical information. These forecasted gross returns are reduced by estimated management fees and expenses. The actual return on plan assets achieved for 2020 was 15.6%. The difference between the actual and expected rate of return on plan assets will be amortized into earnings as described below.

The expected long-term return on plan assets used in determining our 2020 U.S. pension cost was 5.70%. We have assumed a return on plan assets for 2021 of 5.25%. The 2021 expected return on assets was calculated in a manner consistent with 2020. A one-quarter percentage point increase or decrease in the 2021 assumption would be expected to increase or decrease 2021 operating income by approximately $1.0 million.

We use the Society of Actuaries Pri-2012 Generational Mortality Table with MP-2020 projection scales.

Actual results that differ from our various pension and postretirement plan estimates are captured as actuarial gains/losses. When certain thresholds are met, the gains and losses are amortized into future earnings over the average expected lifetime of the plan participants, which is approximately twenty-four years for our U.S. pension plans and twelve years for our U.S. postretirement plans. Changes in assumptions could have significant effects on earnings in future years.

The Company has not materially changed the methodology for calculating pension expense for the years presented. See Note 15, Pension and Other Postretirement Benefit Programs, in Part II, Item 8, "Financial Statements," for additional information.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Sales-related Accruals

At December 31, 2020 and 2019 sales-related accruals for warranty and accommodation claims and sales incentives were $26.1 million and $23.7 million, respectively.

Critical Estimate - Sales-related Accruals

We provide direct customer and end-user warranties for our products and honor approved accommodation claims. Standard warranties cover manufacturing defects that would prevent the product from performing in line with its intended and marketed use. Generally, the terms of these warranties range up to thirty years (limited lifetime) and provide for the repair or replacement of the defective product including limited labor costs. We collect and analyze warranty and accommodation claims data with a focus on the historical amount of claims, the products involved, the amount of time between the warranty claims and the products’ respective sales and the amount of current sales.

We also maintain numerous customer relationships that incorporate different sales incentive programs (primarily volume rebates and promotions). The rebates vary by customer and usually include tiered incentives based on the level of customers’ purchases. Certain promotional allowances are also tied to customer purchase volumes. We estimate the amount of expected annual sales during the course of the year and use the projected sales amount to estimate the cost of the incentive programs. For sales incentive programs that are on the same calendar basis as our fiscal calendar, actual sales information is used in the year-end accruals.

In addition, we also provide for potential early pay discounts and returns based on historical trends.

The amount of actual experience related to these accruals could differ significantly from the estimated amounts during the year. If this occurs, we adjust our accruals accordingly. We record the costs of these accruals as a reduction of gross sales.

The Company has not materially changed the methodology for calculating sales accruals for the years presented. See Schedule II, Valuation and Qualifying Reserves, in Part IV, for additional information.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market Risk

We are exposed to market risk from changes in foreign currency exchange rates that could impact our financial condition, results of operations and cash flows. We enter into derivative contracts, including contracts to hedge our foreign currency exchange rate exposures. Forward swap contracts are entered into for periods consistent with underlying exposure and do not constitute positions independent of those exposures. Derivative financial instruments are used as risk management tools and not for speculative trading purposes. In addition, derivative financial instruments are entered into with a diversified group of major financial institutions in order to manage exposure to potential nonperformance on such instruments. Developments in the capital markets are regularly monitored.

We are subject to interest rate market risk in connection with our Amended ABL Credit Facility.  As of December 31, 2020, our Amended ABL Credit Facility provided variable rate borrowings consisting of a $90.0 million asset-based revolving credit facility. The ABL facility includes a $20.0 million sub-limit for the issuance of letters of credit and a $15.0 million sub-limit for swing loans, net of $5.4 million of letters of credit outstanding at December 31, 2020.  The Amended ABL Credit Facility bears interest at a variable rate based on LIBOR or a base rate plus an applicable margin. An assumed 25 basis point change in interest rates would change interest expense on our Amended ABL Credit Facility by $0.2 million if fully drawn and outstanding for the entire year.

We are subject to additional interest rate market risk in connection with the Term Loan Facility. The Term Loan Facility provides us with a secured term loan credit facility of $70.0 million. Borrowings under the Term Loan Facility bear interest at a rate per annum equal to LIBOR for a three-month interest period. An assumed 25 basis point change in interest rates would change interest expense on the Term Loan Facility by $0.2 million for an entire year.

Counterparty Risk

We only enter into derivative transactions with established counterparties having a credit rating of BBB or better. Counterparty credit default swap levels and credit ratings are monitored on a regular basis in an effort to reduce the risk of counterparty default. All of our derivative transactions with counterparties are governed by master ISDAs with netting arrangements. These agreements can limit our exposure in situations where we have gain and loss positions outstanding with a single counterparty. We neither post nor receive cash collateral with any counterparty for our derivative transactions. These ISDAs do not have credit contingent features; however, a default under our Amended ABL Credit Facility would trigger a default under these agreements.

Exchange Rate Sensitivity

We manufacture and sell our products in a number of countries and, as a result, we are exposed to movements in foreign currency exchange rates. To a large extent, our global manufacturing and sales provide a natural hedge of foreign currency exchange rate movement, as foreign currency expenses generally offset foreign currency revenues. AFI enters into foreign currency forward exchange contracts to reduce its remaining exposure. As of December 31, 2020, our major foreign currency exposures are to the Canadian Dollar, the Chinese Renminbi and the Australian Dollar. A 10% strengthening (or weakening) of all currencies against the U.S. dollar compared to December 31, 2020 levels would decrease (or increase) our forecasted 2021 earnings before income taxes by approximately $0.1 million, including the impact of current foreign currency forward exchange contracts.

The table below details our outstanding currency instruments as of December 31, 2020:

(Dollars in millions)	Maturing in 2021		Maturing in 2022		Total
On Balance Sheet Foreign Exchange Related Derivatives
Notional amounts	$	26.1	$	3.3	$	29.4
Liabilities at fair value, net	(1.0)		(0.1)		(1.1)

We are exposed to changes in foreign currency exchange rates against the U.S. dollar when consolidating our foreign entities. Significant fluctuations could impact our financial results.

Management's Report on Internal Control Over Financial Reporting

Management of Armstrong Flooring, Inc. together with its consolidated subsidiaries (the "Company"), is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Securities Exchange Act Rule 13a-15(f) or 15d-15(f). The Company's internal control over financial reporting is a process designed under the supervision of the Company's principal executive and principal financial officers to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's Consolidated Financial Statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

The Company's internal control over financial reporting includes policies and procedures that:

•Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets of the Company;

•Provide reasonable assurance that transactions are recorded as necessary to permit preparation of Consolidated Financial Statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and the directors of the Company; and

•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 Company's Consolidated 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 and procedures may deteriorate.

Management has assessed the effectiveness of its internal control over financial reporting at December 31, 2020 based on the framework established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has determined that the Company’s internal control over financial reporting was effective at December 31, 2020.

The effectiveness of the Company's internal control over financial reporting at December 31, 2020 has been audited by KPMG, LLP, an independent registered public accounting firm, as stated in their report appearing in this Annual Report on Form 10-K, which expresses an unqualified opinion on the effectiveness of the Company's internal control over financial reporting at December 31, 2020.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Armstrong Flooring, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Armstrong Flooring, Inc. and subsidiaries (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2020, and the related notes and financial statement schedule II (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, 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 March 1, 2021 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for leases as of January 1, 2019 due to the adoption of Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 842, Leases, and the related FASB Accounting Standard Updates.

As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for revenue as of January 1, 2018 due to the adoption of FASB Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, and the related FASB Accounting Standard Updates.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated 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 consolidated 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 consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

32

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated 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 consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Valuation of North American long-lived tangible and intangible assets

As discussed in Note 2 to the consolidated financial statements, the Company reviews long-lived asset groups, which include long-lived tangible and intangible assets, for impairment when indicators of impairment exist, such as operating losses or negative cash flows. The COVID-19 pandemic’s current and expected future impacts, the Company’s recurring losses, and negative cash flows resulted in the identification of a triggering event requiring impairment testing of the North American long-lived tangible and intangible assets (“North American asset group”) in the first quarter of 2020. The Company's test for recoverability, which utilized a probability-weighted income approach, compared the carrying value of the asset group to the sum of i) the undiscounted cash flows expected to result from the use of the North American asset group and ii) the value of the North American asset group upon its eventual disposition.

We identified the evaluation of the North American asset group recoverability test as a critical audit matter. Specifically, subjective and challenging auditor judgment was required to assess the significant assumptions, including:

•revenue growth rates and the Company’s ability to achieve cost-reduction targets, which are affected by expectations about future market or economic conditions and internal cost-reduction initiatives

•the discount rate used in the determination of the value of the North American asset group upon its eventual disposition.

Additionally, the audit effort associated with the evaluation of the recoverability test required specialized skills and knowledge.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the impairment analysis process. This included controls related to the determination of the revenue growth rates, the cost-reduction targets, and discount rate. We evaluated the reasonableness of the Company’s revenue growth rates and cost reduction targets by comparing the revenue growth assumptions and cost reduction targets to the Company’s historical results and to industry data. In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in evaluating the Company’s discount rate by comparing it against a discount rate range that was independently developed using publicly available market data for comparable entities.

Net realizable value of inventory

As discussed in Notes 2 and 10 to the consolidated financial statements, the net inventory balance as of December 31, 2020 was $122.9 million. The Company’s U.S. inventories are valued at the lower of cost or market, and cost is determined using the last-in, first-out ("LIFO") method of accounting. Non-U.S. inventories are valued at the lower of cost or net realizable value, and cost is determined using the first-in, first-out ("FIFO") method of accounting. The Company recently executed product portfolio simplification and inventory optimization initiatives.

We identified the evaluation of the net realizable value of certain inventory in the U.S. as a critical audit matter. Subjective auditor judgment was required in evaluating how the Company’s objectives and strategies affected the net realizable value of certain inventory.

33

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgement to determine the nature and extent of procedures to be performed over the net realizable value of certain inventory. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s process to record inventory at its net realizable value. We evaluated the affect of the Company’s objectives and strategies on the net realizable value of certain inventory by inspecting documentation supporting the product simplification and inventory optimization initiatives. For a selection of certain inventory items, we (1) compared sales prices from recent invoices to the item’s current cost, and (2) assessed whether the cost was greater than its net realizable value considering the product simplification and inventory optimization initiatives. We assessed the sufficiency of audit evidence obtained related to the net realizable value of inventory by evaluating the results of the audit procedures performed.

Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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.

35

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.

NOTE 1. BUSINESS AND BASIS OF PRESENTATION

Business

Armstrong Flooring, Inc. ("AFI" or the "Company") is a leading global producer of resilient flooring products for use primarily in the construction and renovation of residential, commercial and institutional buildings. AFI designs, manufactures, sources and sells resilient flooring products in North America and the Pacific Rim. When we refer to "we," "our," and "us" in this report, we are referring to Armstrong Flooring, Inc., a Delaware corporation, and its consolidated subsidiaries.

Separation

On April 1, 2016, we became an independent company as a result of the separation by Armstrong World Industries, Inc. ("AWI"), a Pennsylvania corporation, of its Resilient Flooring and Wood Flooring segments from its Building Products segment (the "Separation"). The Separation was affected by allocating the assets and liabilities related primarily to the Resilient Flooring and Wood Flooring segments to AFI and then distributing the common stock of AFI to AWI’s shareholders (the "Distribution"). The Separation and Distribution (together, the "Spin-off") resulted in AFI and AWI becoming two independent, publicly traded companies, with AFI owning and operating the Resilient Flooring and Wood Flooring segments and AWI continuing to own and operate a ceilings business.

In connection with the completion of the Spin-off, we entered into several agreements with AWI that provided for the separation and allocation between AFI and AWI of the assets, employees, liabilities and obligations of AWI and its subsidiaries attributable to periods prior to, at and after the Spin-off. These agreements also govern the relationship between AFI and AWI subsequent to the completion of the Spin-off.

On December 31, 2020 we notified AWI of our intention to terminate the Campus Lease Agreement effective June 30, 2021.

Discontinued Operations

On November 14, 2018, AFI entered into a Stock Purchase Agreement with Tarzan Holdco, Inc. ("TZI"), a Delaware corporation and an affiliate of American Industrial Partners ("AIP"), to sell its North American wood flooring business. On December 31, 2018, AIP completed the purchase of all of the issued and outstanding shares of Armstrong Wood Products, Inc., a Delaware corporation, including its direct and indirect wholly owned subsidiaries. See Note 7, Discontinued Operations, for additional information.

COVID

The COVID-19 pandemic has significantly impacted our business and resulted in lower than expected revenue in 2020. In response, we have implemented several cost reduction initiatives including reduced capital spending, implementing a furlough of certain salaried employees and reduced employee benefits for a portion of the year. We are also pursuing a plan expected to monetize non-core assets. The ultimate duration and impact of the pandemic on our future results is unknown. We have incurred net losses for the past several years and negative cash flows from operations beginning in 2019. The pandemic’s impacts, our recurring losses and our negative cash flows resulted in the identification of a triggering event requiring impairment testing of our North American asset group in the first quarter of 2020, the results of which indicated no impairment. There were no significant inventory write-down or significant incremental accounts receivable reserves recorded in 2020. Such charges are possible in the future, which could have a material adverse effect on our future results.

Reclassifications

Certain reclassifications have been made to prior year amounts to conform with current year classifications.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation Policy

The Consolidated Financial Statements and accompanying data in this report include the accounts of AFI and its subsidiaries. Intercompany accounts and transactions have been eliminated from the Consolidated Financial Statements.

Use of Estimates

We prepare our financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"), which requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses. When preparing an estimate, management determines the amount based upon the consideration of relevant internal and external information. Actual results may differ from these estimates.

Revenue Recognition 

We recognize revenue when control of the promised goods is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods.

Our primary performance obligation to our customers is the delivery of flooring products pursuant to purchase orders. Control of the products we sell generally transfers to our customers at the point in time when the goods are shipped. Our standard sales terms are primarily free-on-board shipping point. Our typical payment terms are 30 days and our sales arrangements do not contain any significant financing component for our customers. Our customer arrangements do not generate contract assets or liabilities that are material to the Consolidated Financial Statements.

Each purchase order sets forth the transaction price for the products purchased under that arrangement. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon our customers meeting specified performance criteria, such as a purchasing level over a period of time. We use judgment to estimate the most likely amount of variable consideration at each reporting date.

Costs to obtain a contract are capitalized and amortized over the life of the related contract when the incremental costs directly relate to a specific contract, generates or enhances resources of the company that will be used to satisfy performance of the terms of the contract and the cost are expected to be recovered from the customer. During the fourth quarter of 2020 we capitalized $1.1 million of costs to obtain a contract, related to a single new arrangement, which will be amortized over the three year contractual agreement.

We disaggregate revenue based on customer geography as this category represents the most appropriate depiction of how the nature, timing and uncertainty of revenues and cash flows are impacted by economic factors. See Note 3, Nature of Operations, to the Consolidated Financial Statements for our revenues disaggregated by geography.

Warranties - We provide our customers with a product warranty that provides assurance that the products we sell meet standard specifications and are free of defects. We maintain a reserve for claims and related costs based on historical experience and periodically adjusts these provisions to reflect actual experience. See Note 9, Accounts and Notes Receivable, to the Consolidated Financial Statements for additional information.

Sales Incentives - Sales incentives to customers are reflected as a reduction of net sales.

Shipping and Handling Costs - We treat shipping and handling that occurs after customers obtain control of the products as a fulfillment activity and not as a promised service. Shipping and handling costs are reflected as a component of cost of goods sold.

Taxes - Taxes collected from customers and remitted to governmental authorities are reported on a net basis.

Advertising Costs

We recognize advertising expenses as they are incurred.

(Dollars in millions, except per share data)

Pension and Postretirement Benefits

We have benefit plans that provide for pension, medical and life insurance benefits to certain eligible employees when they retire from active service. The cost of plan amendments that provide for benefits already earned by plan participants is amortized over the expected future working lifetime or the life expectancy of plan participants. A market-related value of plan assets methodology is utilized in the calculation of expected return on assets. The methodology recognizes gains and losses on long duration bonds immediately, while gains and losses on other assets are recognized in the calculation over a five-year period. We use a December 31 measurement date for our pension and postretirement benefit plans. See Note 15, Pension and Other Postretirement Benefit Programs, to the Consolidated Financial Statements for additional information.

Taxes

The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes to reflect the expected future tax consequences of events recognized in the Consolidated Financial Statements. Deferred income tax assets and liabilities are recognized by applying enacted tax rates to temporary differences that exist as of the balance sheet date which result from differences in the timing of reported taxable income between tax and financial reporting.

We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability and foreign source income, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment.

We recognize the tax benefits of an uncertain tax position only if those benefits are more likely than not to be sustained based on existing tax law. Additionally, we establish a reserve for tax positions that are more likely than not to be sustained based on existing tax law, but uncertain in the ultimate benefit to be sustained upon examination by the relevant taxing authorities.  Unrecognized tax benefits are subsequently recognized at the time the more likely than not recognition threshold is met, the tax matter is effectively settled or the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired, whichever is earlier.

We account for all interest and penalties on uncertain income tax positions as income tax expense.

See Note 6, Income Taxes, to the Consolidated Financial Statements for additional information.

Earnings Per Share

Basic earnings per share is computed by dividing the earnings attributable to common shares by the sum of the weighted average number of shares of common stock outstanding during the period and the weighted average number of stock-based awards that have vested but not yet been issued during the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings. See Note 8, Earnings Per Share of Common Stock, to the Consolidated Financial Statements for additional information.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and short-term investments that have maturities of three months or less when purchased. The Company has no restricted cash.

Receivables

We sell the vast majority of our products to select, pre-approved customers using customary trade terms that allow for payment in the future. Customer trade receivables and miscellaneous receivables, net of allowances for current expected credit losses, customer credits and warranties are reported in accounts and notes receivable on a net basis. Cash flows from the collection of receivables are classified as operating cash flows on the Consolidated Statements of Cash Flows.

44

Armstrong Flooring, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

(Dollars in millions, except per share data)

We establish credit-worthiness prior to extending credit. We estimate the net of allowances for current expected credit losses of receivables each period. This estimate is based upon the current and forecasted economic conditions as well as an analysis of prior credit losses by receivable type. Account balances are charged off against the allowance when the potential for recovery is considered remote. We do not have any off-balance-sheet credit exposure related to our customers.

See Note 9, Accounts and Notes Receivable, to the Consolidated Financial Statements for additional information.

Inventories

U.S. inventories are valued at the lower of cost or market and cost is determined using the last-in, first-out ("LIFO") method of accounting. Non-U.S. inventories are valued at the lower of cost or net realizable value and cost is determined using the first-in, first-out ("FIFO") method of accounting. Additionally, inventory balances are adjusted for estimated obsolete or unmarketable inventory equal to the difference between the cost of inventory and its net realizable value or estimated market value, as applicable. See Note 10, Inventories, to the Consolidated Financial Statements for additional information.

Property Plant and Equipment

Property, plant and equipment is recorded at cost reduced by accumulated depreciation. Depreciation expense is recognized on a straight-line basis over assets’ estimated useful lives. Machinery and equipment includes manufacturing equipment (depreciated over 3 to 15 years), computer equipment (depreciated over 3 to 5 years) and office furniture and equipment (depreciated over 5 to 7 years). Within manufacturing equipment, assets that are subject to accelerated obsolescence or wear, such as tooling and engraving equipment, are depreciated over shorter periods (3 to 7 years). Heavy production equipment, such as conveyors, kilns and mixers, are depreciated over longer periods (10 to 15 years). Buildings are depreciated over 15 to 30 years, depending on factors such as type of construction and use. Computer software is amortized over 3 to 7 years.

Property, plant and equipment is tested for impairment when indicators of impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by an asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.

See Note 11, Property, Plant and Equipment, to the Consolidated Financial Statements for additional information.

Intangible Assets

Our indefinite-lived intangible assets are primarily trademarks which are integral to our corporate identity and expected to contribute indefinitely to our corporate cash flows. We conduct our annual impairment test for indefinite-lived intangible assets during the fourth quarter and we conduct interim impairment tests if indicators of potential impairment exist.

An impairment is recognized if the carrying amount of the asset exceeds its fair value. We first perform a qualitative assessment to determine if it is necessary to perform a quantitative impairment test. If a quantitative impairment test is deemed necessary, the method used to determine the fair value of our indefinite-lived intangible assets is the relief-from-royalty method. The principal assumptions used in our application of this method are revenue growth rate, discount rate and royalty rate. Revenue growth rates are derived from those used in our operating plan and strategic planning processes. The discount rate assumption is calculated based upon an estimated weighted average cost of capital, which we believe reflects the overall level of inherent risk and the rate of return a market participant would expect to achieve. The royalty rate assumption represents the estimated contribution of the intangible asset to overall profits. The method used for valuing our indefinite-lived intangible assets did not change from prior periods.

45

Armstrong Flooring, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

(Dollars in millions, except per share data)

Our long-lived intangible assets are primarily contractual arrangements (amortized over 5 years), which includes non-compete agreements, and intellectual property (amortized over 2 to 15 years), which includes developed technology and patents. We review long-lived intangible assets for impairment if indicators of potential impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by the asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.

See Note 12, Intangible Assets, to the Consolidated Financial Statements for additional information.

Foreign Currency Transactions

For our subsidiaries with non-U.S. dollar functional currency, assets and liabilities are translated at period-end exchange rates. Revenues and expenses are translated at exchange rates effective during each month. Foreign currency translation gains or losses are included as a component of accumulated other comprehensive (loss) ("AOCI") within equity. Gains or losses on foreign currency transactions are recognized through net income (loss).

Stock-Based Employee Compensation

We issue stock-based compensation to certain employees and non-employee directors in different forms, including various types of performance-based share compensation including performance-based stock awards ("PSAs"), performance-based stock units ("PSUs"), performance-based restricted stock units ("PBRSUs"); and restricted stock units ("RSUs"). We record stock-based compensation expense based on an estimated grant-date fair value. The expense is reflected as a component of selling, general and administrative (“SG&A”) expenses on our Consolidated Statements of Operations. Stock-based compensation expense includes an estimate for forfeitures and anticipated achievement levels and is generally recognized on a straight-line basis over the vesting period for the entire award. See Note 4, Stock-based Compensation, to the Consolidated Financial Statements for additional information.

Leases

We lease certain real estate (warehouse and office space), vehicles and equipment. For leases with an initial term of one year or less we recognize lease expense for these leases on a straight-line basis over the lease term. Leases with an initial term of one year or more are recorded on the balance sheet. We consider all payments fixed unless there is a material impact to the balance sheet at any given time during the lease period.

We determine if a contract is a lease at inception. Operating leases are included in operating lease assets, accounts payable and accrued expenses and noncurrent operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, current installments of long-term debt and long-term debt in our consolidated balance sheets.

Right-of-use ("ROU") assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. We update these rates annually. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain with a compelling economic reason that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We have elected to combine lease and non-lease components as a single component and account for it as a lease for all asset classes with the exception of land and non-operating buildings. Lease and non-lease components of land and non-operating buildings are generally accounted for separately.

We have elected to use a portfolio approach to determine the discount rate and defined portfolio based on the geographic location of the asset by country and duration of the lease.

See Note 5, Leases, to the Consolidated Financial Statements for additional information.

Recently Adopted Accounting Standards

On January 1, 2020, we adopted Accounting Standards Update ("ASU") 2016-13, "Measurement of Credit Losses on Financial Instruments." The guidance requires immediate recognition of estimated credit losses that are expected to occur over the remaining life of many financial assets. The most notable impact of this ASU related to our processes around the assessment of the adequacy of our allowance for doubtful accounts on trade account receivables. We adopted using the modified retrospective transition method. The adoption of the standard did not have a material impact on our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-13, "Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement." The guidance eliminates, adds and modifies certain disclosure requirements. Adoption of the standard did not have an impact our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-14, "Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans." The guidance changes the disclosure requirements by eliminating certain disclosures that are no longer considered cost beneficial and added new ones that are considered pertinent. Adoption of the standard did not have an impact our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The guidance aligns the requirements for capitalizing implementation costs in a cloud computing arrangement service contract with the requirements for capitalizing implementation costs incurred for an internal use software license. Capitalized implementation costs should be amortized over the term of the service agreement on a straight line basis and should be assessed for impairment in a manner similar to long-lived assets. We adopted using the prospective transition method. This standard did not have a material impact on our financial condition, results of operations or cash flows.

On January 1, 2019, we adopted ASU 2016-02, "Leases." The guidance, and subsequent amendments issued, requires a lessee to recognize the assets and liabilities that arise from a lease agreement. Specifically, this new guidance requires lessees to recognize a liability to make lease payments and a ROU asset representing its right to use the underlying asset for the lease term, with limited exceptions. Adoption of the new standard resulted in the recording of lease assets and lease liabilities of $9.2 million as of January 1, 2019 and the adoption is not expected to have a significant impact on the Company's Consolidated Financial Statements.

On January 1, 2018, we adopted ASU 2014-09, "Revenue from Contracts with Customers" and all the related amendments. The impact of the standard is limited to our accounting for warranties and returns. We adopted the standard using the modified retrospective transition method and we recorded a cumulative catch up adjustment as of January 1, 2018 to increase accumulated deficit in the amount of $4.1 million, increase prepaid expenses and other current assets by $0.4 million and decrease accounts receivable, net by $4.5 million. The adoption of the standard did not have a material impact on our results of operations or cash flows, but did result in new disclosures.

Recently Issued Accounting Standards

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" This new standard eliminates certain exceptions in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, guidance on accounting for franchise taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020. We will adopt ASU 2019-12 as of January 1, 2021 and the adoption is not expected to have a significant impact on our consolidated financial statements.     

Subsequent Events

We have evaluated all activity of the Company and concluded that subsequent events are properly reflected in the Company's Consolidated Financial Statements and Notes as required by U.S. GAAP. See Note 20, Subsequent Events, to the Consolidated Financial Statements for additional information.

NOTE 4. STOCK-BASED COMPENSATION

In April 2016, AFI adopted the Armstrong Flooring, Inc. 2016 Long-Term Incentive Plan (the "2016 LTI Plan") and the Armstrong Flooring, Inc. 2016 Directors' Stock Unit Plan (the "2016 Directors' Plan"), which collectively comprised a new compensation program that allows for the grant of stock-based compensation awards to certain employees and non-employee directors of AFI different forms of benefits, including performance-based awards and RSUs. On June 2, 2017, our stockholders approved an amendment and restatement of the 2016 LTI Plan. Under the 2016 LTI Plan, as amended, our Board of Directors (the "Board") has authorized up to 7,600,000 shares of common stock for issuance. Our Board authorized up to 600,000 shares of common stock that may be issued pursuant to the 2016 Directors' Plan. As of December 31, 2020, 1,185,860 shares and 17,101 shares were available for future grants under the 2016 LTI Plan and the 2016 Directors' Plan, respectively.

Prior to the Spin-off, AWI issued stock-based compensation awards to employees and directors that became employees or directors of AFI. In connection with the Spin-off, these awards were converted into new AFI equity awards using a formula designed to preserve the intrinsic value of the awards immediately prior to the Spin-off. The modification did not result in a change to the value of the awards. The terms and conditions of the AWI awards were replicated and, as necessary, adjusted to ensure that the vesting schedule and economic value of the awards was unchanged by the conversion. At December 31, 2020 only stock option awards remained outstanding related to AWI issued stock-based compensation awards.

Stock-based compensation expense

Stock-based compensation expense is generally recognized on a straight-line basis over the vesting period and is recorded as a component of SG&A. Total stock-based compensation expense included in the Consolidated Statements of Operations and the related tax effects are presented in the table below:

	Year Ended December 31,
	2020		2019		2018
Stock-based compensation expense	$	2.7	$	1.2	$	4.7
Income tax benefit	—		—		1.1

To the extent that the vesting-date fair value of an award is greater than the grant-date fair value, the excess tax benefit is recorded as an income tax benefit in the Consolidated Statements of Operations. For the years ended December 31, 2020, 2019 and 2018 the income tax expense was $0.3 million, $0.1 million and $0.1 million, respectively, related to vested stock-based compensation awards.

As of December 31, 2020, $4.1 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements is expected to be recognized over a weighted-average period of 2.8 years.

Performance-based stock compensation

The Company grants PSAs, PSUs and PBRSUs to key executive employees and certain management employees of AFI under the 2016 LTI Plan. These awards represent units of restricted Company common stock that vest based on the achievement of certain performance or market conditions.

PSAs and PSUs - The performance condition for 75% of the awards is based on earnings before interest, taxes, depreciation and amortization. The performance condition for the remaining 25% of the awards is based on cumulative free cash flow, defined as cash flow from operations, less cash used in investing activities. PSAs issued to key executive employees are also indexed to the achievement of specified levels of absolute total shareholder return and the fair value was measured using a Monte-Carlo simulation on the date of grant. For PSUs that are not indexed to the achievement of specified levels of absolute total shareholder return, the fair value was measured using our stock price on the date of grant. If the performance conditions are met, the awards vest at the conclusion of the performance period, which is generally at the end of the third fiscal year following the date of grant. We did not issue any PSAs during 2020, 2019 or 2018 and did not issue any PSUs during 2020. Details of PSUs issued during 2019 and 2018 are as follows:

	2019		2018
Issued (in thousands)	200.9		354.7
Weighted-average grant date fair value	$	13.25	$	13.97

PBRSUs - The Company issued 691,130 PBRSUs to key executive employees and certain management employees on March 24, 2020. The market condition is based on price targets for the Company's common stock at a future date. Price targets are achieved if the average closing sale stock price of one share of Company Stock, over the 20 trading days following the date of the 2022 year-end earnings release, equals or surpasses the price targets. The number of shares earned is based upon the achievement of four stock price hurdles: $6.00, $7.50, $9.00 and $10.50. Following the first price target achievement, 50% of the overall performance units are earned. With each of the next three Price Target Achievements, an additional 25% of the overall performance units are earned. Payout percentages will be linearly interpolated for stock price performance between the hurdles. The Monte-Carlo valuation provided a weighted average fair value of $0.90 per share for the grant-date fair value.

The Company issued 371,430 PBRSUs to the CEO on September 11, 2019. The market condition is based on price targets for the Company's common stock at a future date. The number of shares earned is based upon the achievement of five stock price hurdles over the period from September 11, 2019 through September 11, 2024. The five per share stock price hurdles are $10.50, $12.25, $14.00, $15.75 and $17.50. A Monte-Carlo valuation was performed to simulate possible future stock prices for AFI over the time remaining period of the award. The Monte-Carlo valuation provided a fair value for each of the five per share stock price hurdles discussed above, respectively: $5.93, $5.28, $4.70, $4.20 and $3.75 (weighted average value of $4.77); and provided derived service periods of 3 years for the first two hurdles and 4 years for the remaining three hurdles.

The following table summarizes the Monte-Carlo inputs and grant-date fair value price used for PBRSU issuances.

	March 24, 2020			September 11, 2019
Grant-date stock price (AFI closing stock price on date of grant)	$	2.18		$	7.43
Assumptions
Risk-free rate of return	0.44		%	1.59		%
Expected volatility	66.29		%	41.45		%
Expected dividend yield	—			—

The risk-free rate of return was determined based on the implied yield available on zero-coupon U.S. Treasury bills at the time of grant with a remaining term equal the expected term of the award. The expected volatility was based on a weighted average of the volatility of AFI and (or) the average volatility of our compensation peer group's volatility. The expected dividend yield was assumed to be zero because, at the time of the grant, we had no plans to declare a dividend.

The table below summarizes activity related to the PSAs, PSUs and PBRSUs.

	PSAs, PSUs and PBRSUs
	Number of Shares (in thousands)	Weighted-Average Grant-Date Fair Value (per share)

The table above contains 4,174 PSUs as of December 31, 2019 which are accounted for as liability awards as they may be settled in cash. These relate to employees in certain international jurisdictions which have prohibitions related to stock settled awards. PSAs with a measurement period that ended on December 31, 2019 resulted in no shares being issued during 2020. PSUs with a measurement period that ended on December 31, 2020 will result in no shares being issued during 2021.

Restricted Stock Awards

RSUs - RSUs were granted to key executive employees and certain management employees of AFI. The RSUs are units representing shares of Company common stock which are converted to shares of Company common stock at the end of the service period. There are no performance or market conditions associated with these awards. For awards issued prior to 2020, vesting generally occurs with one third of the awards vesting at the end of one, two and three years from the date of grant. In 2020, most newly issued RSUs cliff vest three years from the date of grant. The fair value of RSUs was measured using our stock price on the date of grant. Details of RSUs issued during 2020, 2019 and 2018 are as follows:

	2020	2019	2018
Issued (in thousands)	165.0	622.8	308.3

The table above contains 8,334 and 14,118 RSUs as of December 31, 2020 and 2019, respectively, which are accounted for as liability awards as they may be settled in cash. These relate to employees in certain international jurisdictions which have prohibitions related to stock settled awards.

Director Awards - RSUs were granted to our non-employee directors under the 2016 Directors' Plan. These awards generally have a vesting period of one year and any dividends paid prior to vesting are forfeitable if the award does not vest. The awards are generally payable six months following the director’s separation from service on the Board. The fair value of non-employee director RSUs was measured using our stock price on the date of grant. Details of Director awarded RSUs issued during 2020, 2019 and 2018 are as follows:

Our leases have remaining lease terms of one month to nine years. Many leases include one or more options to renew, with renewal terms that can extend the lease term from one month to ten years or more. The exercise of lease renewal options is at our sole discretion. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

As of December 31, 2020, we reviewed our position with regard to foreign unremitted earnings and determined that unremitted earnings would continue to be permanently reinvested. Accordingly, we have not recorded foreign withholding taxes on approximately $15.3 million of undistributed earnings of foreign subsidiaries that could be subject to taxation if remitted to the U.S. because we currently plan to keep these amounts permanently invested overseas. It is not practicable to calculate the residual income tax that would result if these basis differences reversed due to the complexities of the tax law and the hypothetical nature of the calculations.

The tax effects of principal temporary differences between the carrying amounts of assets and liabilities and their tax bases are summarized in the following table. Management believes it is more likely than not that the results of future operations will generate sufficient taxable income in the appropriate jurisdiction and foreign source income to realize deferred tax assets, net of valuation allowances. In arriving at this conclusion, we considered the profit or loss before tax generated for the years 2018 through 2020, as well as future reversals of existing taxable temporary differences and projections of future profit before tax and foreign source income.

We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability and foreign source income, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment.

The following table presents the components of our valuation allowance against deferred income tax assets:

	Year Ended December 31,
	2020		2019
Federal	$	33.1	$	20.3
State	8.0		5.4
Foreign	7.4		10.1
Total	$	48.5	$	35.8

The valuation allowances offset federal, state and foreign deferred tax assets, credits and operating loss carryforwards.

The following is a summary of our NOL carryforwards:

	Year Ended December 31,
	2020		2019
Federal	$	124.1	$	54.7
State	103.0		56.7
Foreign	28.1		42.0

As of December 31, 2020, $74.0 million of state NOL carryforwards expire between 2021 and 2040; and $28.1 million foreign NOL carryforwards expire between 2021 and 2025. The remainder are available for carryforward indefinitely.

We estimate we will need to generate future taxable income of approximately $209.0 million for state income tax purposes during the respective realization periods (ranging from 2021 to 2040) in order to fully realize the net deferred income tax assets discussed above.

We have $1.3 million of unrecognized tax benefits ("UTBs") as of December 31, 2020. Of this amount, $0.1 million, net of federal benefit, if recognized in future periods, would impact the reported effective tax rate.

It is reasonably possible that certain UTBs may increase or decrease within the next twelve months due to tax examination changes, settlement activities, expirations of statute of limitations, or the impact on recognition and measurement considerations related to the results of published tax cases or other similar activities. Over the next twelve months, we estimate UTB's may decrease by $0.1 million related to state statutes expiring.

The following table presents a reconciliation of the total amounts of UTBs, excluding interest and penalties:

	2020		2019		2018
Unrecognized tax benefits as of January 1	$	0.7	$	1.6	$	4.8
Gross change for current year positions	—		—		0.2
Increase for prior period positions	0.7		—		—
(Decreases) for prior period positions	—		(0.9)		(3.4)
Decrease due to statute expirations	(0.1)		—		—
Unrecognized tax benefits balance as of December 31	$	1.3	$	0.7	$	1.6

The 2018 decrease related to prior period positions includes $3.1 million related to discontinued operations.

We conduct business globally, and as a result, we file income tax returns in the U.S., various states and international jurisdictions. In the normal course of business, we are subject to examination by taxing authorities throughout the world in such major jurisdictions as Australia, Canada, China and the U.S. Generally, we have open tax years subject to tax audit on average of between three years and six years. With few exceptions, the statute of limitations is no longer open for state or non-U.S. income tax examinations for the years before 2014. We have not significantly extended any open statutes of limitation for any major jurisdiction and have reviewed and accrued for, where necessary, tax liabilities for open periods. The tax years 2014 through 2019 are subject to future potential tax adjustments.

NOTE 7. DISCONTINUED OPERATIONS

In November 2018, we entered into a definitive agreement to sell our wood business to TZI, an affiliate of AIP. The sale was completed in December 2018. The proceeds from the sale were $90.2 million, net of closing costs, transaction fees and taxes. The transaction was subject to a customary post-closing working capital adjustment process which resulted in a $1.9 million payment to TZI in the third quarter of 2019.

On December 31, 2018, in connection with the sale of our wood business, TZI and AFI entered into agreements related to transition services, intellectual property and subleases.

Pursuant to the transition service agreement AFI provided transitional services in areas including human resources, customer service, operations, finance and IT. In consideration for the services, TZI paid AFI $11.9 million of net fees that varied based on the scope of services provided, plus a $3.0 million administrative fee, which are reflected as a reduction of SG&A expense during year-ended December 31, 2019 and $0.5 million of net fees during year-ended December 31, 2020. TZI reimbursed AFI for AFI’s out-of-pocket costs and expenses in connection with providing the services.

Pursuant to the intellectual property agreement, AFI provided TZI a non-exclusive, royalty-free, non-sublicensable, non-assignable license in and to certain trademarks.

Under the sublease agreements TZI leased certain premises located at the AFI campus through March 30, 2021 with the option to terminate the sublease any time after six months from the effective date of the sublease with 30-days' prior notice. TZI terminated the lease in 2019 and paid a termination fee of $2.5 million. Sublease income received during year-ended December 31, 2019 prior to the termination totaled $1.4 million.

As a part of the transition service agreement, we facilitated sales into Canada for TZI during year-ended December 31, 2019 through our Canadian subsidiary as an agent.

The financial results of the wood business have been classified as discontinued operations for all periods presented. The Consolidated Statements of Cash Flows does not separately report the cash flows of the discontinued operation.

Diluted (loss) per share of common stock from continuing operations	$	(2.90)	$	(2.85)	$	(0.73)

The diluted loss per share was calculated using basic common shares outstanding, as inclusion of potentially dilutive common shares would be anti-dilutive for those calculations.

Performance-based employee compensation awards are considered potentially dilutive in the periods in which the performance conditions are met.

The following awards were excluded from the computation of diluted (loss) earnings per share:

Total	$	43.0	$	36.1

(a) Miscellaneous receivables primarily relates to insurance receivables, the current portion of a distributor note receivable and tax claim receivables not included in Customer trade accounts receivable

On January 1, 2020 we adopted ASU 2016-13, "Measurement of Credit Losses on Financial Instruments." The guidance requires immediate recognition of estimated credit losses that are expected to occur over the remaining life of many financial assets. Generally, we sell our products to select, pre-approved customers whose businesses are affected by changes in economic and market conditions. We consider these factors and the financial condition of each customer when establishing our allowance for expected credit losses. We adopted this ASU using the modified retrospective transition method. The adoption of the standard did not have a material impact on our results of operations or cash flows.

Allowance for product claims represents expected reimbursements for cost associated with warranty repairs and customer accommodation claims, the majority of which is provided to our independent distributors through a credit against accounts receivable from the distributor to AFI.

The following table summarizes the activity for the allowance for product claims:

	Year Ended December 31,

Inventory values were lower than would have been reported on a total FIFO basis by $5.2 million and $4.7 million as of December 31, 2020 and 2019, respectively.

Reserves for inventory obsolescence amounted to $7.0 million and $6.6 million as of December 31, 2020 and 2019, respectively and have been netted against amounts presented above. The increase during 2020 primarily relates to stores and supplies at our South Gate, California facility which the Company has announced will be closed during the first quarter of 2021. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

On September 11, 2019, Michel S. Vermette was appointed Chief Executive Officer of the Company and initiated the implementation of a new multi-year product strategy and inventory optimization plan, which includes focusing on critical products and standardizing procedures to enable better decision making. As a result, we recorded a non-cash inventory write-down of $13.6 million during the third quarter of 2019, primarily related to the write down of inventory in certain product categories to estimated liquidation value.

At September 30, 2020, the Company reclassified to Assets held-for-sale, $19.3 million of primarily land and buildings for two properties that met all related criteria under U.S. GAAP. During December 2020 we sold one of these properties located in Vicksburg, Mississippi which resulted in a gain of $0.2 million. The remaining property still classified as Assets held-for-sale at December 31, 2020 is located in South Gate, California. The ultimate sale of these assets is expected to occur within one year from initial classification as Assets held-for-sale. Long-lived assets that meet the held-for-sale criteria are reported at the lower of their carrying value or fair value, less estimated costs to sell. Assets held-for-sale are recorded as current assets and are presented as a separate caption on the Company's Consolidated Balance Sheets. The following table presents details related to our Assets held-for-sale:

Amended ABL Credit Facility

On June 23, 2020, we entered into a Third Amendment (the "Amendment") to the ABL Credit Facility (the "Amended ABL Credit Facility"), which reduces commitments from $100.0 million to $90.0 million, amends the interest rates applicable to the borrowings, modifies certain financial maintenance and other covenants as well as permits indebtedness under the Term Loan Agreement defined below. The Amended ABL Credit Facility provides for a borrowing base that is derived from our accounts receivable and inventory, collectively, with the equity interests in the guarantors, (the "ABL Priority Collateral"), subject to certain reserves and other limitations. The Amended ABL Credit Facility matures in December 2023.

The Amendment permits us to grant a first priority security interest in real estate, machinery and equipment and intellectual property collateral to Pathlight Capital LP (the "Term Loan Agent") (collectively, the “Term Loan Priority Collateral”). Bank of America, N.A., as administrative agent and collateral agent (in such capacities, the “ABL Agent”) will not have a security interest in the real property securing the Term Loan Agreement (as defined below) but will have a second priority security interest in machinery and equipment and intellectual property constituting Term Loan Priority Collateral.

63

Armstrong Flooring, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

(Dollars in millions, except per share data)

Borrowings under the Amended ABL Credit Facility bear interest at a rate per annum equal to, at our option, a base rate or a Eurodollar rate equal to the London interbank offered rate (“LIBOR”) for the relevant interest period, plus, in each case, an applicable margin determined in accordance with the provisions of the Amendment. The base rate will be the highest of (a) the federal funds rate plus 0.50% (b) the prime rate of Bank of America, N.A. and (c) LIBOR plus 1.00%. The applicable margin for borrowings under the Amended ABL Credit Facility will be determined based on the Company’s Consolidated Leverage Ratio (as defined in the Amendment) and will range from 1.75% to 3.00% with respect to base rate borrowings and 2.75% to 4.00% with respect to Eurodollar rate borrowings. In addition to paying interest on outstanding principal under the Amended ABL Credit Facility, we will pay a commitment fee to the lenders with respect to the unutilized revolving commitments thereunder at a rate ranging from 0.375% to 0.50% depending on the Company’s Consolidated Leverage Ratio. The Amended ABL Credit Facility contains provisions to allow for the transition from LIBOR to the agreed upon successor rate. The weighted average interest rate for the Amended ABL Credit Facility was 5.00% during 2020.

In addition, the Amendment also amends certain financial covenants. The Amended ABL Credit Facility requires, among other things, that we maintain a minimum Consolidated Cash Flow (as defined in the Amendment) for the three-fiscal quarter period ending September 30, 2020, for any four-fiscal quarter period ending thereafter, and during a Financial Covenant Trigger Period (as defined in the Amendment), maintain a minimum Consolidated Fixed Charge Coverage Ratio (as defined in the Amendment) of at least 1.00 to 1.00 (such covenants, the “Financial Covenants”). At December 31, 2020, we were in compliance with all debt covenants.

All obligations under the Amended ABL Credit Facility are guaranteed by each of our wholly owned domestic subsidiaries that individually, or together with its subsidiaries, has assets of more than $1.0 million. All obligations under the Amended ABL Credit Facility, and guarantees of those obligations, are secured by all of the present and future assets of the Company and the guarantors, subject to certain exceptions and exclusions as set forth in the Amended ABL Credit Facility and other security and collateral documents.

Due to its stated maturity, this obligation is presented as a long-term obligation in our Consolidated Balance Sheet. However, we may repay this obligation at any time, without penalty.

As of December 31, 2020, outstanding letters of credit issued under the Amended ABL Credit Facility were $5.4 million and are subject to fees which will be due quarterly in arrears based on the applicable margin described above plus a fronting fee. The total rate for letters of credit was 4.125% as of December 31, 2020.

During the fourth quarter of 2020 there was a reduction in available liquidity under the Amended ABL Credit Facility of $30.0 million until such time as the Company sells our South Gate, California facility. This reduction was in effect at December 31, 2020. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

Term Loan Facility

On June 23, 2020 we also entered into a new term loan facility with Pathlight Capital L.P. as the administrative agent ("Term Loan Agreement"). The Term Loan Agreement provides us with a secured term loan credit facility of $70.0 million (the “Term Loan Facility”). The borrowing base is derived from the Company’s machinery and equipment, intellectual property and real property, subject to certain reserves and other limitations. The Term Loan Facility is scheduled to mature on June 23, 2025.

The principal balance of the Term Loan Facility is payable in quarterly installments beginning in June 2021. We used the proceeds of the Term Loan Facility to pay down the Amended ABL Credit Facility.

Borrowings under the Term Loan Facility will bear interest at a rate per annum equal to LIBOR for a three-month interest period, plus an applicable margin of 12.00%. The Term Loan Facility contains provisions to allow for the transition from LIBOR to the agreed upon successor rate.

(Dollars in millions, except per share data)

We must use cash proceeds from certain dispositions, including sales of real estate, equity and debt issuances and extraordinary events to prepay outstanding loans under the Term Loan Facility, subject to specified exceptions, including the prepayment requirements with respect to the Amended ABL Credit Facility. Prepayments of loans under the Term Loan Facility prior to the third anniversary of the closing date are subject to certain premiums. The sale of our South Gate, California facility is anticipated during the first half of 2021 and would result in an estimated mandatory repayment of approximately $20 million. On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility. See Note 20, Subsequent Events, in Part II, Item 8 “Financial Statements” for additional information.

All obligations under the Term Loan Agreement are guaranteed by each of our wholly owned domestic subsidiaries that individually, or together with its subsidiaries, has assets of more than $1.0 million and are secured by a first priority lien on the Term Priority Collateral and a second priority lien on the ABL Priority Collateral.

The Term Loan Agreement contains a number of covenants that, among other things and subject to certain exceptions, restrict our ability to create liens, to undertake fundamental changes, to incur debt, to sell or dispose of assets, to make investments, to make restricted payments such as dividends, distributions or equity repurchases, to change the nature of our businesses, to enter into transactions with affiliates and to enter into certain burdensome agreements. At December 31, 2020, we were in compliance with all debt covenants.

In addition, the Term Loan Agreement requires us to comply with the Amended ABL Credit Facility financial covenants. The Term Loan Agreement also contains customary affirmative covenants and events of default, including a cross-default provision in respect of certain material indebtedness and a change of control provision. If an event of default occurs, the lenders may choose to accelerate the maturity of the Term Loan Facility and require repayment of all obligations thereunder.

The Company capitalized $7.4 million of fees related to the Term Loan Facility, which will be amortized through 2025 over the life of the Term Loan Facility.

NOTE 15. PENSION AND OTHER POSTRETIREMENT BENEFIT PROGRAMS

We have defined-benefit pension and other postretirement benefit plans covering eligible employees in North America. Benefits from defined-benefit pension plans are based primarily on years of service. We fund our pension plans when appropriate. We fund postretirement benefits on a pay-as-you-go basis, with the retiree paying a portion of the cost for health care benefits by means of deductibles and contributions.

In recent months, our company approved two plan changes. One of our U.S. defined-benefit pension plans, the Retirement Income Plan ("RIP"), was amended as of December 31, 2020 to freeze the accrual of additional benefits for the company's non-union production employees and Lancaster International Association of Machinists and Aerospace Workers participants. Also, our U.S. postretirement plan’s life insurance benefit is no longer being offered for hourly participants at various locations (Beech Creek, Kankakee, South Gate and Stillwater) and for traditional salaried participants who retire on or after January 1, 2021.

We also have defined contribution plans providing for the Company to contribute a specified matching amount for participating employees’ contributions to the plan. The matching amount is dependent upon employee classification, but is generally either a 50% match on the first 6% of pay contributed with a maximum company matching contribution of 3% or a 100% match on the first 4% of pay contributed plus 50% match on the next 4% of pay contributed with a maximum company matching contribution of 6%. Participants become vested in the Company’s matching amount when they have completed three calendar years of company service and worked at least 1,000 hours in each year. Costs for defined-contribution plans were $3.6 million and $5.5 million in 2020 and 2019, respectively. The decrease during 2020 was due to the suspension of Company contributions from May 2020 through September 2020 as a countermeasure to the impact of the COVID 19 pandemic.

Defined-Benefit Pension Plans

The following tables summarize the balance sheet impact of the pension benefit plans, as well as the related benefit obligations, assets, funded status and rate assumptions. The pension benefits disclosures include both the qualified, funded RIP and the Retirement Benefit Equity Plan, which is a nonqualified, unfunded plan designed to provide pension benefits in excess of the limits defined under Sections 415 and 401(a)(17) of the Internal Revenue Code. The disclosures also include our two Canadian pension plans.

Changes in actuarial losses related to the change in the benefit obligation for the U.S. and Canadian pension plans for the years ended December 31, 2020 and 2019, respectively, were primarily due to the decrease in the discount rate each period.

The table below presents the weighted-average assumptions used in computing the benefit obligations and net periodic benefit cost for the defined-benefit pension plans:

	U.S. Pension Plans				Canadian Pension Plans
	2020		2019		2020		2019
Weighted average assumptions used to determine benefit obligations as of December 31:
Discount rate	2.50	%	3.25	%	2.30	%	3.00	%
Rate of compensation increase	3.25	%	3.25	%	n/a		n/a
Weighted average assumptions used to determine net periodic benefit cost for the period:

Basis of Rate-of-Return Assumption

Long-term asset class return assumptions are determined based on the expected performance of the asset classes over 20 years. For the U.S. plans, these forecasted gross returns were reduced by estimated management fees and expenses, yielding a long-term return forecast of 5.70% and 6.30% for the years ended December 31, 2020 and 2019, respectively. For our Canadian plans, these forecasted gross returns were reduced by estimated management fees and expenses, yielding a long-term return forecast of 4.00% and 4.90% for the years ended December 31, 2020 and 2019, respectively.

Defined-benefit pension plans with benefit obligations in excess of plan assets were as follows:

	U.S. Pension Plans				Canadian Pension Plans
	2020		2019		2020		2019
Projected benefit obligation, December 31	$	2.3	$	394.6	$	16.7	$	15.8
Accumulated benefit obligation, December 31	2.3		393.2		16.7		15.8
Fair value of plan assets, December 31	—		380.7		14.4		13.7

Changes in the above table related to U.S. pension plans are due to the one defined benefit pension plan that changed from an underfunded liability position at December 31, 2019 to prepaid asset position at December 31, 2020. This plan had a prepaid asset balance of $1.1 million at December 31, 2020 compared to an underfunded liability balance of $11.8 million at December 31, 2019.

The components of net periodic pension cost for the U.S. and Canadian defined-benefit pension plans were as follows:

	Year Ended December 31,
	U.S. Pension Plans						Canadian Pension Plans
	2020		2019		2018		2020		2019		2018

Investment Policies

Our primary investment objective is to maintain the funded status of the plans such that the likelihood that we will be required to make significant contributions to the plan is limited. This objective is expected to be achieved by:

•Investing a substantial portion of the plan assets in high quality corporate and treasury bonds whose duration is at least equal to that of the plan’s liabilities such that there is a relatively high correlation between the movements of the plan’s liability and asset values.

•Investing in publicly traded equities in order to increase the ratio of plan assets to liabilities over time.

•Limiting investment return volatility by diversifying among additional asset classes with differing expected rates of return and return correlations.

Pension plan assets are required to be reported and disclosed at fair value in the financial statements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Three levels of inputs may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The asset’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

Following is a description of the valuation methodologies used for assets.

Fixed income securities - Consists of registered investment funds, common trust funds, collective trust funds and segregated funds investing in fixed income securities tailored to institutional investors. The fair values of the investments in this class are based on the underlying securities in each fund’s portfolio, which is the amount the fund would receive for the security upon a current sale.

Equities - Consists of investments in funds investing in equities tailored to institutional investors. The fair value of each fund is based on the underlying securities in each fund’s portfolio, which is the amount the fund would receive for the security upon a current sale.

Other - Consists of cash and cash equivalents and other payables and receivables (net). The carrying amounts of cash and cash equivalents approximate fair value due to the short-term maturity of these instruments. The carrying amounts of payables and receivables approximate fair value due to the short-term nature of these instruments.

Defined-Benefit Postretirement Benefit Plans

The following tables summarize the balance sheet impact of the postretirement benefit plans, as well as the related benefit obligations, assets, funded status and rate assumptions.

	2020		2019
Change in benefit obligation:
Projected benefit obligations as January 1	$	65.3	$	62.2
Service cost	—		0.2
Interest cost	1.9		2.5
Plan participants' contributions	1.2		2.2
Plan amendments	(6.4)		(2.6)
Actuarial loss	4.5		10.0
Benefits paid	(6.9)		(9.2)
Projected benefit obligation as of December 31	59.6		65.3
Change in plan assets:
Fair value of plan assets as January 1	—		—
Employer contribution	5.7		7.0
Plan participants' contribution	1.2		2.2
Benefits paid	(6.9)		(9.2)
Fair value of plan assets as of December 31	—		—
Funded status of the plans	$	(59.6)	$	(65.3)

The change in actuarial loss related to the change in the benefit obligation for the postretirement benefit plans for the year ended December 31, 2020 was primarily due to the decrease in the discount rate and new claim costs being higher than assumed, partially offset by a gain from the census data updates. The change in actuarial loss related to the change in the benefit obligation for the postretirement benefit plans for the year ended December 31, 2019 was primarily due to the decrease in the discount rate, medical trend assumption changes and new claim costs being higher than assumed.

The table below presents the weighted-average assumptions used in computing the benefit obligations and net periodic benefit cost for the U.S. defined-benefit postretirement benefit plans:

	2020		2019
Weighted average discount rate used to determine benefit obligations as of December 31	2.45	%	3.20	%
Weighted average discount rate used to determine net periodic benefit cost	3.20	%	4.30	%

The components of net periodic postretirement (benefit) cost were as follows:

	Year Ended December 31,
	2020		2019		2018
Service cost of benefits earned during the period	$	—	$	0.2	$	0.4
Interest cost on accumulated postretirement benefit obligations	1.9		2.5		2.6
Amortization of prior service (credit)	(0.2)		—		—
Amortization of net actuarial (gain)	(4.8)		(3.1)		(2.5)
Net periodic postretirement (benefit) cost	$	(3.1)	$	(0.4)	$	0.5

As a result of the elimination of future life insurance benefits for certain employees, we recorded a curtailment gain of $1.8 million in 2020 in other income. This gain is not reflected in the above table.

Net actuarial gain (loss)	$	(106.7)	$	(123.1)	$	(4.9)	$	(4.8)	$	25.6	$	30.5

We expect to contribute $0.1 million each to our U.S. and Canadian defined-benefit pension plans and $4.1 million to our U.S. postretirement benefit plans in 2021.

Future Benefit Payments

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid over the next ten years for our U.S. and Canadian plans:

	U.S. Pension Benefits		Canadian Pension Benefits		Postretirement Benefits
2021	$	19.9	$	1.3	$	4.1
2022	20.9		1.3		3.8
2023	21.6		1.2		3.6
2024	21.7		1.2		3.5
2025	22.1		1.1		3.4
2026-2030	114.1		5.3		15.7

These estimated benefit payments are based on assumptions about future events. Actual benefit payments may vary significantly from these estimates.

NOTE 16. DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk from changes in foreign currency exchange rates that could impact our financial condition, results of operations and cash flows. We enter into derivative contracts, including contracts to hedge our foreign currency exchange rate exposures. Exposure to individual counterparties is controlled and derivative financial instruments are entered into with a diversified group of major financial institutions. Forward swap contracts are entered into for periods consistent with underlying exposure and do not constitute positions independent of those exposures. Derivative instruments are viewed as risk management tools by the Company and are not used for trading or speculative purposes. All derivative instruments are recorded on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply, or the Company elects not to apply hedge accounting.

Counterparty Risk

We only enter into derivative transactions with established counterparties having a credit rating of BBB or better. Counterparty credit default swap levels and credit ratings are monitored on a regular basis in an effort to reduce the risk of counterparty default. All of our derivative transactions with counterparties are governed by master International Swap and Derivatives Association agreements (“ISDAs”) with netting arrangements. These agreements can limit exposure in situations where gain and loss positions are outstanding with a single counterparty. We neither post nor receive cash collateral with any counterparty for our derivative transactions. These ISDAs do not have credit contingent features; however, a default under our Credit Facility would trigger a default under these agreements.

Currency Rate Risk – Sales and Purchases

We manufacture and sell our products in a number of countries and, as a result, we are exposed to movements in foreign currency exchange rates. To a large extent, our global manufacturing and sales provide a natural hedge of foreign currency exchange rate movement, as foreign currency expenses generally offset foreign currency revenues. We manage our cash flow exposures on a net basis and use derivatives to hedge the majority of our unmatched foreign currency cash inflows and outflows. Before considering the impacts of any hedging, our major foreign currency exposures as of December 31, 2020, based on operating profits by currency, are from the Canadian Dollar, the Chinese Renminbi and the Australian Dollar.

We use foreign currency forward exchange contracts to reduce our exposure to the risk that the eventual net cash inflows and outflows resulting from the sale of products to foreign customers and purchases from foreign suppliers will be adversely affected by changes in exchange rates. These derivative instruments are used for forecasted transactions and are classified as cash flow hedges. These cash flow hedges are executed quarterly, generally up to 18 months forward. The notional amount of these hedges was $17.3 million and $23.1 million as of December 31, 2020 and 2019, respectively. Gains and losses on these instruments are recorded in AOCI, to the extent effective, until the underlying transaction is recognized in earnings. The mark-to-market gains or losses on ineffective portions of hedges are recognized in SG&A expense.

Currency Rate Risk – Intercompany Loans and Dividends

We may use foreign currency forward exchange contracts to hedge exposures created by cross-currency intercompany loans and dividends. The translation adjustments related to these loans are recorded in other (income) expense, net. The offsetting gains and losses on the related derivative contracts are also recorded in other (income) expense, net. These contracts are decreased or increased as repayments are made or additional intercompany loans are extended or adjusted for intercompany dividend activity as necessary. The notional amount of these hedges was $12.1 million and $16.6 million as of December 31, 2020 and 2019, respectively.

Derivatives not designated as hedging instruments:
Foreign exchange contracts	—		0.1		—		0.3
Total	$	—	$	1.1	$	—	$	0.7

The following tables summarize the impact of the effective portion of derivative instruments on the Consolidated Statements of Operations and Comprehensive Income (Loss):

	Gains (losses) recognized in other comprehensive income (loss)						(Losses) gains reclassified from AOCI
	Year Ended December 31,						Year Ended December 31,
	2020		2019		2018		2020		2019		2018
Cash flow hedges:
Foreign exchange contracts	$	0.3	$	(0.8)	$	2.0	$	(0.2)	$	0.7	$	(0.3)

	Gains recognized in income
	Year Ended December 31,
	2020		2019		2018
Non-designated hedges:
Foreign exchange contracts	$	0.3	$	0.1	$	1.5

Derivative assets are classified within prepaid expenses and other current assets as well as other non-current assets on the Consolidated Balance Sheets. Derivative liabilities are classified within accounts payable and accrued expenses as well as other long-term liabilities on the Consolidated Balance Sheets. Gains (losses) from derivatives were included in net sales and cost of goods sold on the Consolidated Statements of Operations. As of December 31, 2020, the amount of existing gains in AOCI expected to be recognized in earnings over the next twelve months is $0.8 million.

The fair values of our net foreign currency contracts were estimated from market quotes, which are considered to be Level 1 inputs.

Borrowings under the Amended ABL Credit Facility and the Term Loan Facility are quoted in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the liability (Level 2 inputs).

We do not have any assets or liabilities that are valued using Level 3 unobservable inputs.

NOTE 18. STOCKHOLDERS' EQUITY

Common Stock Repurchase Plan

On March 6, 2017, we announced that our Board had approved a share repurchase program pursuant to which we were authorized to repurchase up to $50.0 million of our outstanding shares of common stock. From inception of the share repurchase program through May 3, 2019, we repurchased approximately 2.5 million shares for a total cost of $41.0 million, with an average price of $16.23 per share. On May 3, 2019, we announced that our Board had authorized an increased share repurchase program for an additional $50.0 million beyond the $41.0 million already repurchased under the prior share repurchase program, effective immediately. Repurchases under the new program could be made through open market, block and privately negotiated transactions, including Rule 10b5-1 plans, at times and in such amounts as management deemed appropriate, subject to market and business conditions, regulatory requirements and other factors.

On May 17, 2019, we announced the commencement of a modified "Dutch auction" self-tender offer to repurchase up to $50.0 million in cash of shares of our common stock. As a result of the auction, on June 21, 2019 we purchased 4,504,504 shares of common stock at a purchase price of $11.42 per share, for a total cost of $51.4 million , including fees and expenses. After the completion of the tender offer, we have no remaining authorization to purchase further shares.

NOTE 19. LITIGATION AND RELATED MATTERS

Environmental Matters

Environmental Compliance

Our manufacturing and research facilities are affected by various federal, state and local requirements relating to the discharge of materials and the protection of the environment. We make expenditures necessary for compliance with applicable environmental requirements at each of our operating facilities. These regulatory requirements continually change, therefore we cannot predict with certainty future expenditures associated with compliance with environmental requirements.

Environmental Sites

In connection with our current or legacy manufacturing operations, or those of former owners, we may from time to time become involved in the investigation, closure and/or remediation of existing or potential environmental contamination under the Comprehensive Environmental Response, Compensation and Liability Act as well as state or international Superfund and similar type environmental laws. For those matters, we may have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies; however, we cannot predict with certainty the future identification of or expenditure for any investigation, closure or remediation of any environmental site.

Summary of Financial Position

There were no material liabilities recorded as of December 31, 2020 and December 31, 2019 for potential environmental liabilities that we consider probable and for which a reasonable estimate of the probable liability could be made.

Other Claims

We are involved in various lawsuits, claims, investigations and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, relationships with suppliers, distributors and competitors, employees and other matters. For example, we are currently a party to various litigation matters that involve product liability, tort liability and other claims under a wide range of allegations, including illness due to exposure to certain chemicals used in the workplace, or medical conditions arising from exposure to product ingredients or the presence of trace contaminants. In some cases, these allegations involve multiple defendants and relate to legacy products that we and other defendants purportedly manufactured or sold. We believe these claims and allegations to be without merit and intend to defend them vigorously. For these matters, we also may have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies.

On November 15, 2019, a shareholder filed a putative class action complaint in the United States District Court for the Central District of California alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5, promulgated thereunder, based on alleged false and/or misleading statements or omissions made between March 6, 2018 and November 4, 2019. On March 2, 2020, the court issued an order appointing a lead plaintiff and lead counsel. On July 2, 2020, the lead plaintiff filed an amended complaint asserting similar violations and expanding the alleged class period to cover alleged false and/or misleading statements or omissions made between March 6, 2018 and March 3, 2020. On August 17, 2020, the Company moved to dismiss the amended complaint, and the lead plaintiff filed an opposition on October 1, 2020. On November 30, 2020, the Company reached a settlement in principle to fully resolve this matter. The settlement agreement, which is subject to final court approval, provides in part for a settlement payment of $3.75 million in exchange for the dismissal and a release of all claims against the defendants. Neither the Company nor any individual defendant admits any wrongdoing through the settlement agreement. The $3.75 million settlement payment will be paid by our insurance provider under our relevant insurance policy. On January 15, 2021, the lead plaintiff filed a motion for preliminary approval of the settlement. On February 23, 2021, the court granted preliminary approval of the settlement, preliminary certification of the settlement class and approval to provide notice to the class. The final settlement approval hearing is currently scheduled for July 19, 2021. The Company has recognized a corresponding $3.75 million insurance receivable and $3.75 million accrued expense related to this matter in the captions Accounts and notes receivable, net and Accounts payable and accrued expenses on the Consolidated Balance Sheets as of December 31, 2020.

While complete assurance cannot be given to the outcome of these proceedings, we do not believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows.

NOTE 20. SUBSEQUENT EVENTS

On February 25, 2021, the Company entered into a definitive agreement to sell its South Gate, California facility for a purchase price of $76.7 million.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company maintains a system of disclosure controls and procedures to give reasonable assurance that information required to be disclosed in the Company's reports filed or submitted under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. These controls and procedures also give reasonable assurance that information required to be disclosed in such reports is accumulated and communicated to management to allow timely decisions regarding required disclosures.

During the evaluation of disclosure controls and procedures and our internal control over financial reporting as of December 31, 2019 conducted during the preparation of our financial statements, which were included in our Annual Report on Form 10-K for the year ended December 31, 2019, our management identified a material weakness in internal control over financial reporting relating to the design and implementation of information technology general controls ("ITGCs") over two information technology ("IT") systems that support our processing of certain sales incentives, which are recorded as a reduction of sales and accounts receivable. As a result, business process automated and manual controls that are dependent on the affected ITGCs were ineffective because they could have been adversely impacted. This control deficiency was a result of: risk-assessment processes inadequate to identify and evaluate responses to risks in the financial reporting process; and failure to implement monitoring control activities when involving a third party service provider. This control deficiency did not result in any identified misstatements to the Consolidated Financial Statements as of and for the year ended December 31, 2019 and there were no changes to previously released financial results. However, the control deficiency created a reasonable possibility that a material misstatement to our Consolidated Financial Statements would not be prevented or detected on a timely basis and, therefore, we concluded that as of December 31, 2019, our internal control over financial reporting was not effective.

Throughout 2020, we performed risk assessment procedures over the activities involving the processing and recording of certain sales incentives. This assessment included an evaluation of the ITGCs for the two IT systems that support our processing of these sales incentives, as well as the business process automated and manual controls that are dependent on the affected ITGCs. As a result, management implemented controls designed to prevent or detect a material misstatement. Those new controls were fully implemented and sufficient testing was performed to conclude that the applicable controls were operating effectively as of December 31, 2020. As such, Management believes that, as of December 31, 2020, the deficiencies contributing to the previously identified material weakness have been satisfactorily remediated.

Changes in Internal Control over Financial Reporting

The following changes in internal control over financial reporting occurred during 2020:

On June 26, 2020, the Company and Douglas B. Bingham mutually agreed that Mr. Bingham would step down from his position as Senior Vice President, CFO and Treasurer and principal financial officer. The role and responsibilities of principal financial officer of the Company previously held by Mr. Bingham were assumed by Gregory D. Waina, as Interim Chief Financial Officer.

On July 28, 2020, Tracy L. Marines resigned from her position as Vice President and Controller effective August 28, 2020 at which time Gregory D. Waina, the Company's Interim Chief Financial Officer (principal financial officer) assumed the role and responsibilities of principal accounting officer of the Company. On and effective as of September 14, 2020, Phillip J. Gaudreau was appointed to the position of Vice President and Controller at which time he assumed the role and responsibilities of principal accounting officer.

Amy P. Trojanowski was appointed to the position and responsibilities of Senior Vice President and Chief Financial Officer and assumed the role and responsibilities of principal finance officer effective October 19, 2020. In connection with this appointment, and also effective as of October 19, 2020, Gregory D. Waina resigned from his position as the Company’s Interim Chief Financial Officer (and principal financial officer) and remained with the Company in a consulting capacity to ensure a smooth transition. The consulting relationship with Gregory D. Waina ended during the fourth quarter of 2020.

79

Except for the remediation of the material weakness described above and the forgoing, no other changes in our internal control over financial reporting occurred during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Controls Over Financial Reporting is included in Part II, Item 8, “Financial Statements.” The effectiveness of the Company’s internal control over financial reporting at December 31, 2020 has been audited by KMPG LLP, an independent registered public accounting firm, as stated in the Report of Independent Registered Public Accounting Firm appearing in Part II, Item 8, “Financial Statements.”

BUSINESS AND BASIS OF PRESENTATION

BUSINESS AND BASIS OF PRESENTATION

Business

Armstrong Flooring, Inc. ("AFI" or the "Company") is a leading global producer of resilient flooring products for use primarily in the construction and renovation of residential, commercial and institutional buildings. AFI designs, manufactures, sources and sells resilient flooring products in North America and the Pacific Rim. When we refer to "we," "our," and "us" in this report, we are referring to Armstrong Flooring, Inc., a Delaware corporation, and its consolidated subsidiaries.

Separation

On April 1, 2016, we became an independent company as a result of the separation by Armstrong World Industries, Inc. ("AWI"), a Pennsylvania corporation, of its Resilient Flooring and Wood Flooring segments from its Building Products segment (the "Separation"). The Separation was affected by allocating the assets and liabilities related primarily to the Resilient Flooring and Wood Flooring segments to AFI and then distributing the common stock of AFI to AWI’s shareholders (the "Distribution"). The Separation and Distribution (together, the "Spin-off") resulted in AFI and AWI becoming two independent, publicly traded companies, with AFI owning and operating the Resilient Flooring and Wood Flooring segments and AWI continuing to own and operate a ceilings business.

In connection with the completion of the Spin-off, we entered into several agreements with AWI that provided for the separation and allocation between AFI and AWI of the assets, employees, liabilities and obligations of AWI and its subsidiaries attributable to periods prior to, at and after the Spin-off. These agreements also govern the relationship between AFI and AWI subsequent to the completion of the Spin-off.

On December 31, 2020 we notified AWI of our intention to terminate the Campus Lease Agreement effective June 30, 2021.

Discontinued Operations

On November 14, 2018, AFI entered into a Stock Purchase Agreement with Tarzan Holdco, Inc. ("TZI"), a Delaware corporation and an affiliate of American Industrial Partners ("AIP"), to sell its North American wood flooring business. On December 31, 2018, AIP completed the purchase of all of the issued and outstanding shares of Armstrong Wood Products, Inc., a Delaware corporation, including its direct and indirect wholly owned subsidiaries. See Note 7, Discontinued Operations, for additional information.

COVID

The COVID-19 pandemic has significantly impacted our business and resulted in lower than expected revenue in 2020. In response, we have implemented several cost reduction initiatives including reduced capital spending, implementing a furlough of certain salaried employees and reduced employee benefits for a portion of the year. We are also pursuing a plan expected to monetize non-core assets. The ultimate duration and impact of the pandemic on our future results is unknown. We have incurred net losses for the past several years and negative cash flows from operations beginning in 2019. The pandemic’s impacts, our recurring losses and our negative cash flows resulted in the identification of a triggering event requiring impairment testing of our North American asset group in the first quarter of 2020, the results of which indicated no impairment. There were no significant inventory write-down or significant incremental accounts receivable reserves recorded in 2020. Such charges are possible in the future, which could have a material adverse effect on our future results.

Reclassifications

Certain reclassifications have been made to prior year amounts to conform with current year classifications.

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation Policy

The Consolidated Financial Statements and accompanying data in this report include the accounts of AFI and its subsidiaries. Intercompany accounts and transactions have been eliminated from the Consolidated Financial Statements.

Use of Estimates

We prepare our financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"), which requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses. When preparing an estimate, management determines the amount based upon the consideration of relevant internal and external information. Actual results may differ from these estimates.

Revenue Recognition 

We recognize revenue when control of the promised goods is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods.

Our primary performance obligation to our customers is the delivery of flooring products pursuant to purchase orders. Control of the products we sell generally transfers to our customers at the point in time when the goods are shipped. Our standard sales terms are primarily free-on-board shipping point. Our typical payment terms are 30 days and our sales arrangements do not contain any significant financing component for our customers. Our customer arrangements do not generate contract assets or liabilities that are material to the Consolidated Financial Statements.

Each purchase order sets forth the transaction price for the products purchased under that arrangement. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon our customers meeting specified performance criteria, such as a purchasing level over a period of time. We use judgment to estimate the most likely amount of variable consideration at each reporting date.

Costs to obtain a contract are capitalized and amortized over the life of the related contract when the incremental costs directly relate to a specific contract, generates or enhances resources of the company that will be used to satisfy performance of the terms of the contract and the cost are expected to be recovered from the customer. During the fourth quarter of 2020 we capitalized $1.1 million of costs to obtain a contract, related to a single new arrangement, which will be amortized over the three year contractual agreement.

We disaggregate revenue based on customer geography as this category represents the most appropriate depiction of how the nature, timing and uncertainty of revenues and cash flows are impacted by economic factors. See Note 3, Nature of Operations, to the Consolidated Financial Statements for our revenues disaggregated by geography.

Warranties - We provide our customers with a product warranty that provides assurance that the products we sell meet standard specifications and are free of defects. We maintain a reserve for claims and related costs based on historical experience and periodically adjusts these provisions to reflect actual experience. See Note 9, Accounts and Notes Receivable, to the Consolidated Financial Statements for additional information.

Sales Incentives - Sales incentives to customers are reflected as a reduction of net sales.

Shipping and Handling Costs - We treat shipping and handling that occurs after customers obtain control of the products as a fulfillment activity and not as a promised service. Shipping and handling costs are reflected as a component of cost of goods sold.

Taxes - Taxes collected from customers and remitted to governmental authorities are reported on a net basis.

Advertising Costs

We recognize advertising expenses as they are incurred.

Pension and Postretirement Benefits

We have benefit plans that provide for pension, medical and life insurance benefits to certain eligible employees when they retire from active service. The cost of plan amendments that provide for benefits already earned by plan participants is amortized over the expected future working lifetime or the life expectancy of plan participants. A market-related value of plan assets methodology is utilized in the calculation of expected return on assets. The methodology recognizes gains and losses on long duration bonds immediately, while gains and losses on other assets are recognized in the calculation over a five-year period. We use a December 31 measurement date for our pension and postretirement benefit plans. See Note 15, Pension and Other Postretirement Benefit Programs, to the Consolidated Financial Statements for additional information.

Taxes

The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes to reflect the expected future tax consequences of events recognized in the Consolidated Financial Statements. Deferred income tax assets and liabilities are recognized by applying enacted tax rates to temporary differences that exist as of the balance sheet date which result from differences in the timing of reported taxable income between tax and financial reporting.

We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability and foreign source income, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment.

We recognize the tax benefits of an uncertain tax position only if those benefits are more likely than not to be sustained based on existing tax law. Additionally, we establish a reserve for tax positions that are more likely than not to be sustained based on existing tax law, but uncertain in the ultimate benefit to be sustained upon examination by the relevant taxing authorities.  Unrecognized tax benefits are subsequently recognized at the time the more likely than not recognition threshold is met, the tax matter is effectively settled or the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired, whichever is earlier.

We account for all interest and penalties on uncertain income tax positions as income tax expense.

See Note 6, Income Taxes, to the Consolidated Financial Statements for additional information.

Earnings Per Share

Basic earnings per share is computed by dividing the earnings attributable to common shares by the sum of the weighted average number of shares of common stock outstanding during the period and the weighted average number of stock-based awards that have vested but not yet been issued during the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings. See Note 8, Earnings Per Share of Common Stock, to the Consolidated Financial Statements for additional information.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and short-term investments that have maturities of three months or less when purchased. The Company has no restricted cash.

Receivables

We sell the vast majority of our products to select, pre-approved customers using customary trade terms that allow for payment in the future. Customer trade receivables and miscellaneous receivables, net of allowances for current expected credit losses, customer credits and warranties are reported in accounts and notes receivable on a net basis. Cash flows from the collection of receivables are classified as operating cash flows on the Consolidated Statements of Cash Flows.

We establish credit-worthiness prior to extending credit. We estimate the net of allowances for current expected credit losses of receivables each period. This estimate is based upon the current and forecasted economic conditions as well as an analysis of prior credit losses by receivable type. Account balances are charged off against the allowance when the potential for recovery is considered remote. We do not have any off-balance-sheet credit exposure related to our customers.

See Note 9, Accounts and Notes Receivable, to the Consolidated Financial Statements for additional information.

Inventories

U.S. inventories are valued at the lower of cost or market and cost is determined using the last-in, first-out ("LIFO") method of accounting. Non-U.S. inventories are valued at the lower of cost or net realizable value and cost is determined using the first-in, first-out ("FIFO") method of accounting. Additionally, inventory balances are adjusted for estimated obsolete or unmarketable inventory equal to the difference between the cost of inventory and its net realizable value or estimated market value, as applicable. See Note 10, Inventories, to the Consolidated Financial Statements for additional information.

Property Plant and Equipment

Property, plant and equipment is recorded at cost reduced by accumulated depreciation. Depreciation expense is recognized on a straight-line basis over assets’ estimated useful lives. Machinery and equipment includes manufacturing equipment (depreciated over 3 to 15 years), computer equipment (depreciated over 3 to 5 years) and office furniture and equipment (depreciated over 5 to 7 years). Within manufacturing equipment, assets that are subject to accelerated obsolescence or wear, such as tooling and engraving equipment, are depreciated over shorter periods (3 to 7 years). Heavy production equipment, such as conveyors, kilns and mixers, are depreciated over longer periods (10 to 15 years). Buildings are depreciated over 15 to 30 years, depending on factors such as type of construction and use. Computer software is amortized over 3 to 7 years.

Property, plant and equipment is tested for impairment when indicators of impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by an asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.

See Note 11, Property, Plant and Equipment, to the Consolidated Financial Statements for additional information.

Intangible Assets

Our indefinite-lived intangible assets are primarily trademarks which are integral to our corporate identity and expected to contribute indefinitely to our corporate cash flows. We conduct our annual impairment test for indefinite-lived intangible assets during the fourth quarter and we conduct interim impairment tests if indicators of potential impairment exist.

An impairment is recognized if the carrying amount of the asset exceeds its fair value. We first perform a qualitative assessment to determine if it is necessary to perform a quantitative impairment test. If a quantitative impairment test is deemed necessary, the method used to determine the fair value of our indefinite-lived intangible assets is the relief-from-royalty method. The principal assumptions used in our application of this method are revenue growth rate, discount rate and royalty rate. Revenue growth rates are derived from those used in our operating plan and strategic planning processes. The discount rate assumption is calculated based upon an estimated weighted average cost of capital, which we believe reflects the overall level of inherent risk and the rate of return a market participant would expect to achieve. The royalty rate assumption represents the estimated contribution of the intangible asset to overall profits. The method used for valuing our indefinite-lived intangible assets did not change from prior periods.

Our long-lived intangible assets are primarily contractual arrangements (amortized over 5 years), which includes non-compete agreements, and intellectual property (amortized over 2 to 15 years), which includes developed technology and patents. We review long-lived intangible assets for impairment if indicators of potential impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by the asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.

See Note 12, Intangible Assets, to the Consolidated Financial Statements for additional information.

Foreign Currency Transactions

For our subsidiaries with non-U.S. dollar functional currency, assets and liabilities are translated at period-end exchange rates. Revenues and expenses are translated at exchange rates effective during each month. Foreign currency translation gains or losses are included as a component of accumulated other comprehensive (loss) ("AOCI") within equity. Gains or losses on foreign currency transactions are recognized through net income (loss).

Stock-Based Employee Compensation

We issue stock-based compensation to certain employees and non-employee directors in different forms, including various types of performance-based share compensation including performance-based stock awards ("PSAs"), performance-based stock units ("PSUs"), performance-based restricted stock units ("PBRSUs"); and restricted stock units ("RSUs"). We record stock-based compensation expense based on an estimated grant-date fair value. The expense is reflected as a component of selling, general and administrative (“SG&A”) expenses on our Consolidated Statements of Operations. Stock-based compensation expense includes an estimate for forfeitures and anticipated achievement levels and is generally recognized on a straight-line basis over the vesting period for the entire award. See Note 4, Stock-based Compensation, to the Consolidated Financial Statements for additional information.

Leases

We lease certain real estate (warehouse and office space), vehicles and equipment. For leases with an initial term of one year or less we recognize lease expense for these leases on a straight-line basis over the lease term. Leases with an initial term of one year or more are recorded on the balance sheet. We consider all payments fixed unless there is a material impact to the balance sheet at any given time during the lease period.

We determine if a contract is a lease at inception. Operating leases are included in operating lease assets, accounts payable and accrued expenses and noncurrent operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, current installments of long-term debt and long-term debt in our consolidated balance sheets.

Right-of-use ("ROU") assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. We update these rates annually. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain with a compelling economic reason that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We have elected to combine lease and non-lease components as a single component and account for it as a lease for all asset classes with the exception of land and non-operating buildings. Lease and non-lease components of land and non-operating buildings are generally accounted for separately.

We have elected to use a portfolio approach to determine the discount rate and defined portfolio based on the geographic location of the asset by country and duration of the lease.

See Note 5, Leases, to the Consolidated Financial Statements for additional information.

Recently Adopted Accounting Standards

On January 1, 2020, we adopted Accounting Standards Update ("ASU") 2016-13, "Measurement of Credit Losses on Financial Instruments." The guidance requires immediate recognition of estimated credit losses that are expected to occur over the remaining life of many financial assets. The most notable impact of this ASU related to our processes around the assessment of the adequacy of our allowance for doubtful accounts on trade account receivables. We adopted using the modified retrospective transition method. The adoption of the standard did not have a material impact on our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-13, "Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement." The guidance eliminates, adds and modifies certain disclosure requirements. Adoption of the standard did not have an impact our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-14, "Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans." The guidance changes the disclosure requirements by eliminating certain disclosures that are no longer considered cost beneficial and added new ones that are considered pertinent. Adoption of the standard did not have an impact our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The guidance aligns the requirements for capitalizing implementation costs in a cloud computing arrangement service contract with the requirements for capitalizing implementation costs incurred for an internal use software license. Capitalized implementation costs should be amortized over the term of the service agreement on a straight line basis and should be assessed for impairment in a manner similar to long-lived assets. We adopted using the prospective transition method. This standard did not have a material impact on our financial condition, results of operations or cash flows.

On January 1, 2019, we adopted ASU 2016-02, "Leases." The guidance, and subsequent amendments issued, requires a lessee to recognize the assets and liabilities that arise from a lease agreement. Specifically, this new guidance requires lessees to recognize a liability to make lease payments and a ROU asset representing its right to use the underlying asset for the lease term, with limited exceptions. Adoption of the new standard resulted in the recording of lease assets and lease liabilities of $9.2 million as of January 1, 2019 and the adoption is not expected to have a significant impact on the Company's Consolidated Financial Statements.

On January 1, 2018, we adopted ASU 2014-09, "Revenue from Contracts with Customers" and all the related amendments. The impact of the standard is limited to our accounting for warranties and returns. We adopted the standard using the modified retrospective transition method and we recorded a cumulative catch up adjustment as of January 1, 2018 to increase accumulated deficit in the amount of $4.1 million, increase prepaid expenses and other current assets by $0.4 million and decrease accounts receivable, net by $4.5 million. The adoption of the standard did not have a material impact on our results of operations or cash flows, but did result in new disclosures.

Recently Issued Accounting Standards

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" This new standard eliminates certain exceptions in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, guidance on accounting for franchise taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020. We will adopt ASU 2019-12 as of January 1, 2021 and the adoption is not expected to have a significant impact on our consolidated financial statements.     

Subsequent Events

We have evaluated all activity of the Company and concluded that subsequent events are properly reflected in the Company's Consolidated Financial Statements and Notes as required by U.S. GAAP. See Note 20, Subsequent Events, to the Consolidated Financial Statements for additional information.

Stock-Based Compensation

12 Months Ended

Dec. 31, 2020

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

STOCK-BASED COMPENSATION

In April 2016, AFI adopted the Armstrong Flooring, Inc. 2016 Long-Term Incentive Plan (the "2016 LTI Plan") and the Armstrong Flooring, Inc. 2016 Directors' Stock Unit Plan (the "2016 Directors' Plan"), which collectively comprised a new compensation program that allows for the grant of stock-based compensation awards to certain employees and non-employee directors of AFI different forms of benefits, including performance-based awards and RSUs. On June 2, 2017, our stockholders approved an amendment and restatement of the 2016 LTI Plan. Under the 2016 LTI Plan, as amended, our Board of Directors (the "Board") has authorized up to 7,600,000 shares of common stock for issuance. Our Board authorized up to 600,000 shares of common stock that may be issued pursuant to the 2016 Directors' Plan. As of December 31, 2020, 1,185,860 shares and 17,101 shares were available for future grants under the 2016 LTI Plan and the 2016 Directors' Plan, respectively.

Prior to the Spin-off, AWI issued stock-based compensation awards to employees and directors that became employees or directors of AFI. In connection with the Spin-off, these awards were converted into new AFI equity awards using a formula designed to preserve the intrinsic value of the awards immediately prior to the Spin-off. The modification did not result in a change to the value of the awards. The terms and conditions of the AWI awards were replicated and, as necessary, adjusted to ensure that the vesting schedule and economic value of the awards was unchanged by the conversion. At December 31, 2020 only stock option awards remained outstanding related to AWI issued stock-based compensation awards.

Stock-based compensation expense

Stock-based compensation expense is generally recognized on a straight-line basis over the vesting period and is recorded as a component of SG&A. Total stock-based compensation expense included in the Consolidated Statements of Operations and the related tax effects are presented in the table below:

	Year Ended December 31,
	2020		2019		2018
Stock-based compensation expense	$	2.7	$	1.2	$	4.7
Income tax benefit	—		—		1.1

To the extent that the vesting-date fair value of an award is greater than the grant-date fair value, the excess tax benefit is recorded as an income tax benefit in the Consolidated Statements of Operations. For the years ended December 31, 2020, 2019 and 2018 the income tax expense was $0.3 million, $0.1 million and $0.1 million, respectively, related to vested stock-based compensation awards.

As of December 31, 2020, $4.1 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements is expected to be recognized over a weighted-average period of 2.8 years.

Performance-based stock compensation

The Company grants PSAs, PSUs and PBRSUs to key executive employees and certain management employees of AFI under the 2016 LTI Plan. These awards represent units of restricted Company common stock that vest based on the achievement of certain performance or market conditions.

PSAs and PSUs - The performance condition for 75% of the awards is based on earnings before interest, taxes, depreciation and amortization. The performance condition for the remaining 25% of the awards is based on cumulative free cash flow, defined as cash flow from operations, less cash used in investing activities. PSAs issued to key executive employees are also indexed to the achievement of specified levels of absolute total shareholder return and the fair value was measured using a Monte-Carlo simulation on the date of grant. For PSUs that are not indexed to the achievement of specified levels of absolute total shareholder return, the fair value was measured using our stock price on the date of grant. If the performance conditions are met, the awards vest at the conclusion of the performance period, which is generally at the end of the third fiscal year following the date of grant. We did not issue any PSAs during 2020, 2019 or 2018 and did not issue any PSUs during 2020. Details of PSUs issued during 2019 and 2018 are as follows:

	2019		2018
Issued (in thousands)	200.9		354.7
Weighted-average grant date fair value	$	13.25	$	13.97

PBRSUs - The Company issued 691,130 PBRSUs to key executive employees and certain management employees on March 24, 2020. The market condition is based on price targets for the Company's common stock at a future date. Price targets are achieved if the average closing sale stock price of one share of Company Stock, over the 20 trading days following the date of the 2022 year-end earnings release, equals or surpasses the price targets. The number of shares earned is based upon the achievement of four stock price hurdles: $6.00, $7.50, $9.00 and $10.50. Following the first price target achievement, 50% of the overall performance units are earned. With each of the next three Price Target Achievements, an additional 25% of the overall performance units are earned. Payout percentages will be linearly interpolated for stock price performance between the hurdles. The Monte-Carlo valuation provided a weighted average fair value of $0.90 per share for the grant-date fair value.

The Company issued 371,430 PBRSUs to the CEO on September 11, 2019. The market condition is based on price targets for the Company's common stock at a future date. The number of shares earned is based upon the achievement of five stock price hurdles over the period from September 11, 2019 through September 11, 2024. The five per share stock price hurdles are $10.50, $12.25, $14.00, $15.75 and $17.50. A Monte-Carlo valuation was performed to simulate possible future stock prices for AFI over the time remaining period of the award. The Monte-Carlo valuation provided a fair value for each of the five per share stock price hurdles discussed above, respectively: $5.93, $5.28, $4.70, $4.20 and $3.75 (weighted average value of $4.77); and provided derived service periods of 3 years for the first two hurdles and 4 years for the remaining three hurdles.

The following table summarizes the Monte-Carlo inputs and grant-date fair value price used for PBRSU issuances.

	March 24, 2020			September 11, 2019
Grant-date stock price (AFI closing stock price on date of grant)	$	2.18		$	7.43
Assumptions
Risk-free rate of return	0.44		%	1.59		%
Expected volatility	66.29		%	41.45		%
Expected dividend yield	—			—

The risk-free rate of return was determined based on the implied yield available on zero-coupon U.S. Treasury bills at the time of grant with a remaining term equal the expected term of the award. The expected volatility was based on a weighted average of the volatility of AFI and (or) the average volatility of our compensation peer group's volatility. The expected dividend yield was assumed to be zero because, at the time of the grant, we had no plans to declare a dividend.

The table below summarizes activity related to the PSAs, PSUs and PBRSUs.

The table above contains 4,174 PSUs as of December 31, 2019 which are accounted for as liability awards as they may be settled in cash. These relate to employees in certain international jurisdictions which have prohibitions related to stock settled awards. PSAs with a measurement period that ended on December 31, 2019 resulted in no shares being issued during 2020. PSUs with a measurement period that ended on December 31, 2020 will result in no shares being issued during 2021.

Restricted Stock Awards

RSUs - RSUs were granted to key executive employees and certain management employees of AFI. The RSUs are units representing shares of Company common stock which are converted to shares of Company common stock at the end of the service period. There are no performance or market conditions associated with these awards. For awards issued prior to 2020, vesting generally occurs with one third of the awards vesting at the end of one, two and three years from the date of grant. In 2020, most newly issued RSUs cliff vest three years from the date of grant. The fair value of RSUs was measured using our stock price on the date of grant. Details of RSUs issued during 2020, 2019 and 2018 are as follows:

	2020	2019	2018
Issued (in thousands)	165.0	622.8	308.3

The table above contains 8,334 and 14,118 RSUs as of December 31, 2020 and 2019, respectively, which are accounted for as liability awards as they may be settled in cash. These relate to employees in certain international jurisdictions which have prohibitions related to stock settled awards.

Director Awards - RSUs were granted to our non-employee directors under the 2016 Directors' Plan. These awards generally have a vesting period of one year and any dividends paid prior to vesting are forfeitable if the award does not vest. The awards are generally payable six months following the director’s separation from service on the Board. The fair value of non-employee director RSUs was measured using our stock price on the date of grant. Details of Director awarded RSUs issued during 2020, 2019 and 2018 are as follows:

	2020	2019		2018
Issued (in thousands)	171.2	57.0		67.3

As of December 31, 2020, we reviewed our position with regard to foreign unremitted earnings and determined that unremitted earnings would continue to be permanently reinvested. Accordingly, we have not recorded foreign withholding taxes on approximately $15.3 million of undistributed earnings of foreign subsidiaries that could be subject to taxation if remitted to the U.S. because we currently plan to keep these amounts permanently invested overseas. It is not practicable to calculate the residual income tax that would result if these basis differences reversed due to the complexities of the tax law and the hypothetical nature of the calculations.

The following table presents the differences between our income tax benefit at the U.S. federal statutory income tax rate and our effective income tax rate:

	Year Ended December 31,
	2020		2019		2018

The tax effects of principal temporary differences between the carrying amounts of assets and liabilities and their tax bases are summarized in the following table. Management believes it is more likely than not that the results of future operations will generate sufficient taxable income in the appropriate jurisdiction and foreign source income to realize deferred tax assets, net of valuation allowances. In arriving at this conclusion, we considered the profit or loss before tax generated for the years 2018 through 2020, as well as future reversals of existing taxable temporary differences and projections of future profit before tax and foreign source income.

	December 31, 2020		December 31, 2019
Deferred income tax assets (liabilities)
Postretirement and postemployment benefits	$	15.8	$	17.5

Net deferred income tax assets	$	2.0	$	2.9

We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability and foreign source income, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment.

The following table presents the components of our valuation allowance against deferred income tax assets:

	Year Ended December 31,
	2020		2019
Federal	$	33.1	$	20.3
State	8.0		5.4
Foreign	7.4		10.1
Total	$	48.5	$	35.8

The valuation allowances offset federal, state and foreign deferred tax assets, credits and operating loss carryforwards.

The following is a summary of our NOL carryforwards:

	Year Ended December 31,
	2020		2019
Federal	$	124.1	$	54.7
State	103.0		56.7
Foreign	28.1		42.0

As of December 31, 2020, $74.0 million of state NOL carryforwards expire between 2021 and 2040; and $28.1 million foreign NOL carryforwards expire between 2021 and 2025. The remainder are available for carryforward indefinitely.

We estimate we will need to generate future taxable income of approximately $209.0 million for state income tax purposes during the respective realization periods (ranging from 2021 to 2040) in order to fully realize the net deferred income tax assets discussed above.

We have $1.3 million of unrecognized tax benefits ("UTBs") as of December 31, 2020. Of this amount, $0.1 million, net of federal benefit, if recognized in future periods, would impact the reported effective tax rate.

It is reasonably possible that certain UTBs may increase or decrease within the next twelve months due to tax examination changes, settlement activities, expirations of statute of limitations, or the impact on recognition and measurement considerations related to the results of published tax cases or other similar activities. Over the next twelve months, we estimate UTB's may decrease by $0.1 million related to state statutes expiring.

The following table presents a reconciliation of the total amounts of UTBs, excluding interest and penalties:

	2020		2019		2018
Unrecognized tax benefits as of January 1	$	0.7	$	1.6	$	4.8
Gross change for current year positions	—		—		0.2
Increase for prior period positions	0.7		—		—
(Decreases) for prior period positions	—		(0.9)		(3.4)
Decrease due to statute expirations	(0.1)		—		—
Unrecognized tax benefits balance as of December 31	$	1.3	$	0.7	$	1.6

The 2018 decrease related to prior period positions includes $3.1 million related to discontinued operations.

We conduct business globally, and as a result, we file income tax returns in the U.S., various states and international jurisdictions. In the normal course of business, we are subject to examination by taxing authorities throughout the world in such major jurisdictions as Australia, Canada, China and the U.S. Generally, we have open tax years subject to tax audit on average of between three years and six years. With few exceptions, the statute of limitations is no longer open for state or non-U.S. income tax examinations for the years before 2014. We have not significantly extended any open statutes of limitation for any major jurisdiction and have reviewed and accrued for, where necessary, tax liabilities for open periods. The tax years 2014 through 2019 are subject to future potential tax adjustments.

Discontinued Operations

DISCONTINUED OPERATIONS

In November 2018, we entered into a definitive agreement to sell our wood business to TZI, an affiliate of AIP. The sale was completed in December 2018. The proceeds from the sale were $90.2 million, net of closing costs, transaction fees and taxes. The transaction was subject to a customary post-closing working capital adjustment process which resulted in a $1.9 million payment to TZI in the third quarter of 2019.

On December 31, 2018, in connection with the sale of our wood business, TZI and AFI entered into agreements related to transition services, intellectual property and subleases.

Pursuant to the transition service agreement AFI provided transitional services in areas including human resources, customer service, operations, finance and IT. In consideration for the services, TZI paid AFI $11.9 million of net fees that varied based on the scope of services provided, plus a $3.0 million administrative fee, which are reflected as a reduction of SG&A expense during year-ended December 31, 2019 and $0.5 million of net fees during year-ended December 31, 2020. TZI reimbursed AFI for AFI’s out-of-pocket costs and expenses in connection with providing the services.

Pursuant to the intellectual property agreement, AFI provided TZI a non-exclusive, royalty-free, non-sublicensable, non-assignable license in and to certain trademarks.

Under the sublease agreements TZI leased certain premises located at the AFI campus through March 30, 2021 with the option to terminate the sublease any time after six months from the effective date of the sublease with 30-days' prior notice. TZI terminated the lease in 2019 and paid a termination fee of $2.5 million. Sublease income received during year-ended December 31, 2019 prior to the termination totaled $1.4 million.

As a part of the transition service agreement, we facilitated sales into Canada for TZI during year-ended December 31, 2019 through our Canadian subsidiary as an agent.

The financial results of the wood business have been classified as discontinued operations for all periods presented. The Consolidated Statements of Cash Flows does not separately report the cash flows of the discontinued operation.

The following is a summary of the operating results of the wood business, which are included in discontinued operations. These results exclude overhead allocations.

Total	$	43.0	$	36.1

(a) Miscellaneous receivables primarily relates to insurance receivables, the current portion of a distributor note receivable and tax claim receivables not included in Customer trade accounts receivable

On January 1, 2020 we adopted ASU 2016-13, "Measurement of Credit Losses on Financial Instruments." The guidance requires immediate recognition of estimated credit losses that are expected to occur over the remaining life of many financial assets. Generally, we sell our products to select, pre-approved customers whose businesses are affected by changes in economic and market conditions. We consider these factors and the financial condition of each customer when establishing our allowance for expected credit losses. We adopted this ASU using the modified retrospective transition method. The adoption of the standard did not have a material impact on our results of operations or cash flows.

Allowance for product claims represents expected reimbursements for cost associated with warranty repairs and customer accommodation claims, the majority of which is provided to our independent distributors through a credit against accounts receivable from the distributor to AFI.

The following table summarizes the activity for the allowance for product claims:

Retirement Benefits [Abstract]

Pension and Other Postretirement Benefit Programs

PENSION AND OTHER POSTRETIREMENT BENEFIT PROGRAMS

We have defined-benefit pension and other postretirement benefit plans covering eligible employees in North America. Benefits from defined-benefit pension plans are based primarily on years of service. We fund our pension plans when appropriate. We fund postretirement benefits on a pay-as-you-go basis, with the retiree paying a portion of the cost for health care benefits by means of deductibles and contributions.

In recent months, our company approved two plan changes. One of our U.S. defined-benefit pension plans, the Retirement Income Plan ("RIP"), was amended as of December 31, 2020 to freeze the accrual of additional benefits for the company's non-union production employees and Lancaster International Association of Machinists and Aerospace Workers participants. Also, our U.S. postretirement plan’s life insurance benefit is no longer being offered for hourly participants at various locations (Beech Creek, Kankakee, South Gate and Stillwater) and for traditional salaried participants who retire on or after January 1, 2021.

We also have defined contribution plans providing for the Company to contribute a specified matching amount for participating employees’ contributions to the plan. The matching amount is dependent upon employee classification, but is generally either a 50% match on the first 6% of pay contributed with a maximum company matching contribution of 3% or a 100% match on the first 4% of pay contributed plus 50% match on the next 4% of pay contributed with a maximum company matching contribution of 6%. Participants become vested in the Company’s matching amount when they have completed three calendar years of company service and worked at least 1,000 hours in each year. Costs for defined-contribution plans were $3.6 million and $5.5 million in 2020 and 2019, respectively. The decrease during 2020 was due to the suspension of Company contributions from May 2020 through September 2020 as a countermeasure to the impact of the COVID 19 pandemic.

Defined-Benefit Pension Plans

The following tables summarize the balance sheet impact of the pension benefit plans, as well as the related benefit obligations, assets, funded status and rate assumptions. The pension benefits disclosures include both the qualified, funded RIP and the Retirement Benefit Equity Plan, which is a nonqualified, unfunded plan designed to provide pension benefits in excess of the limits defined under Sections 415 and 401(a)(17) of the Internal Revenue Code. The disclosures also include our two Canadian pension plans.

Accumulated benefit obligation as of December 31	$	418.4	$	393.2	$	17.1	$	16.3

Changes in actuarial losses related to the change in the benefit obligation for the U.S. and Canadian pension plans for the years ended December 31, 2020 and 2019, respectively, were primarily due to the decrease in the discount rate each period.

The table below presents the weighted-average assumptions used in computing the benefit obligations and net periodic benefit cost for the defined-benefit pension plans:

	U.S. Pension Plans				Canadian Pension Plans
	2020		2019		2020		2019
Weighted average assumptions used to determine benefit obligations as of December 31:
Discount rate	2.50	%	3.25	%	2.30	%	3.00	%
Rate of compensation increase	3.25	%	3.25	%	n/a		n/a
Weighted average assumptions used to determine net periodic benefit cost for the period:
Discount rate	3.25	%	4.40	%	3.00	%	3.80	%
Expected return on plan assets	5.70	%	6.30	%	4.00	%	4.90	%
Rate of compensation increase	3.25	%	3.25	%	n/a		n/a

Basis of Rate-of-Return Assumption

Long-term asset class return assumptions are determined based on the expected performance of the asset classes over 20 years. For the U.S. plans, these forecasted gross returns were reduced by estimated management fees and expenses, yielding a long-term return forecast of 5.70% and 6.30% for the years ended December 31, 2020 and 2019, respectively. For our Canadian plans, these forecasted gross returns were reduced by estimated management fees and expenses, yielding a long-term return forecast of 4.00% and 4.90% for the years ended December 31, 2020 and 2019, respectively.

Defined-benefit pension plans with benefit obligations in excess of plan assets were as follows:

	U.S. Pension Plans				Canadian Pension Plans
	2020		2019		2020		2019
Projected benefit obligation, December 31	$	2.3	$	394.6	$	16.7	$	15.8
Accumulated benefit obligation, December 31	2.3		393.2		16.7		15.8
Fair value of plan assets, December 31	—		380.7		14.4		13.7

Changes in the above table related to U.S. pension plans are due to the one defined benefit pension plan that changed from an underfunded liability position at December 31, 2019 to prepaid asset position at December 31, 2020. This plan had a prepaid asset balance of $1.1 million at December 31, 2020 compared to an underfunded liability balance of $11.8 million at December 31, 2019.

The components of net periodic pension cost for the U.S. and Canadian defined-benefit pension plans were as follows:

	Year Ended December 31,
	U.S. Pension Plans						Canadian Pension Plans
	2020		2019		2018		2020		2019		2018

Net periodic pension cost	$	3.9	$	5.7	$	6.9	$	0.3	$	0.3	$	—

Investment Policies

Our primary investment objective is to maintain the funded status of the plans such that the likelihood that we will be required to make significant contributions to the plan is limited. This objective is expected to be achieved by:

•Investing a substantial portion of the plan assets in high quality corporate and treasury bonds whose duration is at least equal to that of the plan’s liabilities such that there is a relatively high correlation between the movements of the plan’s liability and asset values.

•Investing in publicly traded equities in order to increase the ratio of plan assets to liabilities over time.

•Limiting investment return volatility by diversifying among additional asset classes with differing expected rates of return and return correlations.

Each asset class used has a defined asset allocation target and allowable range. The tables below show the asset allocation targets and the December 31, 2020 and 2019 positions for each asset class:

	Target Weight at		Position at December 31,
	December 31, 2020		2020		2019
U.S. Asset Class
Fixed income securities	60	%	54	%	55	%
Equities	40	%	46	%	45	%
Canadian Asset Class
Fixed income securities	50	%	50	%	50	%
Equities	48	%	48	%	48	%
Other	2	%	2	%	2	%

Pension plan assets are required to be reported and disclosed at fair value in the financial statements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Three levels of inputs may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The asset’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The following tables set forth by level within the fair value hierarchy a summary of the U.S. and Canadian defined-benefit pension plan assets, net of payables for administrative expenses, measured at fair value on a recurring basis:

Following is a description of the valuation methodologies used for assets.

Fixed income securities - Consists of registered investment funds, common trust funds, collective trust funds and segregated funds investing in fixed income securities tailored to institutional investors. The fair values of the investments in this class are based on the underlying securities in each fund’s portfolio, which is the amount the fund would receive for the security upon a current sale.

Equities - Consists of investments in funds investing in equities tailored to institutional investors. The fair value of each fund is based on the underlying securities in each fund’s portfolio, which is the amount the fund would receive for the security upon a current sale.

Other - Consists of cash and cash equivalents and other payables and receivables (net). The carrying amounts of cash and cash equivalents approximate fair value due to the short-term maturity of these instruments. The carrying amounts of payables and receivables approximate fair value due to the short-term nature of these instruments.

Defined-Benefit Postretirement Benefit Plans

The following tables summarize the balance sheet impact of the postretirement benefit plans, as well as the related benefit obligations, assets, funded status and rate assumptions.

	2020		2019
Change in benefit obligation:
Projected benefit obligations as January 1	$	65.3	$	62.2
Service cost	—		0.2
Interest cost	1.9		2.5
Plan participants' contributions	1.2		2.2

Benefits paid	(6.9)		(9.2)
Fair value of plan assets as of December 31	—		—
Funded status of the plans	$	(59.6)	$	(65.3)

The change in actuarial loss related to the change in the benefit obligation for the postretirement benefit plans for the year ended December 31, 2020 was primarily due to the decrease in the discount rate and new claim costs being higher than assumed, partially offset by a gain from the census data updates. The change in actuarial loss related to the change in the benefit obligation for the postretirement benefit plans for the year ended December 31, 2019 was primarily due to the decrease in the discount rate, medical trend assumption changes and new claim costs being higher than assumed.

The table below presents the weighted-average assumptions used in computing the benefit obligations and net periodic benefit cost for the U.S. defined-benefit postretirement benefit plans:

	2020		2019
Weighted average discount rate used to determine benefit obligations as of December 31	2.45	%	3.20	%
Weighted average discount rate used to determine net periodic benefit cost	3.20	%	4.30	%

The components of net periodic postretirement (benefit) cost were as follows:

	Year Ended December 31,
	2020		2019		2018
Service cost of benefits earned during the period	$	—	$	0.2	$	0.4
Interest cost on accumulated postretirement benefit obligations	1.9		2.5		2.6
Amortization of prior service (credit)	(0.2)		—		—
Amortization of net actuarial (gain)	(4.8)		(3.1)		(2.5)
Net periodic postretirement (benefit) cost	$	(3.1)	$	(0.4)	$	0.5

As a result of the elimination of future life insurance benefits for certain employees, we recorded a curtailment gain of $1.8 million in 2020 in other income. This gain is not reflected in the above table.

For measurement purposes, an average rate of annual increase in the per capita cost of covered health care benefits of 6.7% for pre-65 retirees was assumed for 2021, decreasing ratably to an ultimate rate of 4.5% by 2027.

Derivative Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk from changes in foreign currency exchange rates that could impact our financial condition, results of operations and cash flows. We enter into derivative contracts, including contracts to hedge our foreign currency exchange rate exposures. Exposure to individual counterparties is controlled and derivative financial instruments are entered into with a diversified group of major financial institutions. Forward swap contracts are entered into for periods consistent with underlying exposure and do not constitute positions independent of those exposures. Derivative instruments are viewed as risk management tools by the Company and are not used for trading or speculative purposes. All derivative instruments are recorded on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply, or the Company elects not to apply hedge accounting.

Counterparty Risk

We only enter into derivative transactions with established counterparties having a credit rating of BBB or better. Counterparty credit default swap levels and credit ratings are monitored on a regular basis in an effort to reduce the risk of counterparty default. All of our derivative transactions with counterparties are governed by master International Swap and Derivatives Association agreements (“ISDAs”) with netting arrangements. These agreements can limit exposure in situations where gain and loss positions are outstanding with a single counterparty. We neither post nor receive cash collateral with any counterparty for our derivative transactions. These ISDAs do not have credit contingent features; however, a default under our Credit Facility would trigger a default under these agreements.

Currency Rate Risk – Sales and Purchases

We manufacture and sell our products in a number of countries and, as a result, we are exposed to movements in foreign currency exchange rates. To a large extent, our global manufacturing and sales provide a natural hedge of foreign currency exchange rate movement, as foreign currency expenses generally offset foreign currency revenues. We manage our cash flow exposures on a net basis and use derivatives to hedge the majority of our unmatched foreign currency cash inflows and outflows. Before considering the impacts of any hedging, our major foreign currency exposures as of December 31, 2020, based on operating profits by currency, are from the Canadian Dollar, the Chinese Renminbi and the Australian Dollar.

We use foreign currency forward exchange contracts to reduce our exposure to the risk that the eventual net cash inflows and outflows resulting from the sale of products to foreign customers and purchases from foreign suppliers will be adversely affected by changes in exchange rates. These derivative instruments are used for forecasted transactions and are classified as cash flow hedges. These cash flow hedges are executed quarterly, generally up to 18 months forward. The notional amount of these hedges was $17.3 million and $23.1 million as of December 31, 2020 and 2019, respectively. Gains and losses on these instruments are recorded in AOCI, to the extent effective, until the underlying transaction is recognized in earnings. The mark-to-market gains or losses on ineffective portions of hedges are recognized in SG&A expense.

Currency Rate Risk – Intercompany Loans and Dividends

We may use foreign currency forward exchange contracts to hedge exposures created by cross-currency intercompany loans and dividends. The translation adjustments related to these loans are recorded in other (income) expense, net. The offsetting gains and losses on the related derivative contracts are also recorded in other (income) expense, net. These contracts are decreased or increased as repayments are made or additional intercompany loans are extended or adjusted for intercompany dividend activity as necessary. The notional amount of these hedges was $12.1 million and $16.6 million as of December 31, 2020 and 2019, respectively.

Financial Statement Impacts

The following table presents the classification of derivative assets and liabilities within the Consolidated Balance Sheets. The foreign exchange contracts outstanding are presented gross as we have not netted derivative assets with derivative liabilities:

STOCKHOLDERS' EQUITY

Common Stock Repurchase Plan

On March 6, 2017, we announced that our Board had approved a share repurchase program pursuant to which we were authorized to repurchase up to $50.0 million of our outstanding shares of common stock. From inception of the share repurchase program through May 3, 2019, we repurchased approximately 2.5 million shares for a total cost of $41.0 million, with an average price of $16.23 per share. On May 3, 2019, we announced that our Board had authorized an increased share repurchase program for an additional $50.0 million beyond the $41.0 million already repurchased under the prior share repurchase program, effective immediately. Repurchases under the new program could be made through open market, block and privately negotiated transactions, including Rule 10b5-1 plans, at times and in such amounts as management deemed appropriate, subject to market and business conditions, regulatory requirements and other factors.

On May 17, 2019, we announced the commencement of a modified "Dutch auction" self-tender offer to repurchase up to $50.0 million in cash of shares of our common stock. As a result of the auction, on June 21, 2019 we purchased 4,504,504 shares of common stock at a purchase price of $11.42 per share, for a total cost of $51.4 million , including fees and expenses. After the completion of the tender offer, we have no remaining authorization to purchase further shares.

Litigation And Related Matters

LITIGATION AND RELATED MATTERS

Environmental Matters

Environmental Compliance

Our manufacturing and research facilities are affected by various federal, state and local requirements relating to the discharge of materials and the protection of the environment. We make expenditures necessary for compliance with applicable environmental requirements at each of our operating facilities. These regulatory requirements continually change, therefore we cannot predict with certainty future expenditures associated with compliance with environmental requirements.

Environmental Sites

In connection with our current or legacy manufacturing operations, or those of former owners, we may from time to time become involved in the investigation, closure and/or remediation of existing or potential environmental contamination under the Comprehensive Environmental Response, Compensation and Liability Act as well as state or international Superfund and similar type environmental laws. For those matters, we may have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies; however, we cannot predict with certainty the future identification of or expenditure for any investigation, closure or remediation of any environmental site.

Summary of Financial Position

There were no material liabilities recorded as of December 31, 2020 and December 31, 2019 for potential environmental liabilities that we consider probable and for which a reasonable estimate of the probable liability could be made.

Other Claims

We are involved in various lawsuits, claims, investigations and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, relationships with suppliers, distributors and competitors, employees and other matters. For example, we are currently a party to various litigation matters that involve product liability, tort liability and other claims under a wide range of allegations, including illness due to exposure to certain chemicals used in the workplace, or medical conditions arising from exposure to product ingredients or the presence of trace contaminants. In some cases, these allegations involve multiple defendants and relate to legacy products that we and other defendants purportedly manufactured or sold. We believe these claims and allegations to be without merit and intend to defend them vigorously. For these matters, we also may have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies.

On November 15, 2019, a shareholder filed a putative class action complaint in the United States District Court for the Central District of California alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5, promulgated thereunder, based on alleged false and/or misleading statements or omissions made between March 6, 2018 and November 4, 2019. On March 2, 2020, the court issued an order appointing a lead plaintiff and lead counsel. On July 2, 2020, the lead plaintiff filed an amended complaint asserting similar violations and expanding the alleged class period to cover alleged false and/or misleading statements or omissions made between March 6, 2018 and March 3, 2020. On August 17, 2020, the Company moved to dismiss the amended complaint, and the lead plaintiff filed an opposition on October 1, 2020. On November 30, 2020, the Company reached a settlement in principle to fully resolve this matter. The settlement agreement, which is subject to final court approval, provides in part for a settlement payment of $3.75 million in exchange for the dismissal and a release of all claims against the defendants. Neither the Company nor any individual defendant admits any wrongdoing through the settlement agreement. The $3.75 million settlement payment will be paid by our insurance provider under our relevant insurance policy. On January 15, 2021, the lead plaintiff filed a motion for preliminary approval of the settlement. On February 23, 2021, the court granted preliminary approval of the settlement, preliminary certification of the settlement class and approval to provide notice to the class. The final settlement approval hearing is currently scheduled for July 19, 2021. The Company has recognized a corresponding $3.75 million insurance receivable and $3.75 million accrued expense related to this matter in the captions Accounts and notes receivable, net and Accounts payable and accrued expenses on the Consolidated Balance Sheets as of December 31, 2020.

While complete assurance cannot be given to the outcome of these proceedings, we do not believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows.

Summary of Significant Accounting Policies (Policies)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation Policy

Consolidation Policy

The Consolidated Financial Statements and accompanying data in this report include the accounts of AFI and its subsidiaries. Intercompany accounts and transactions have been eliminated from the Consolidated Financial Statements.

Use of Estimates

Use of Estimates

We prepare our financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"), which requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses. When preparing an estimate, management determines the amount based upon the consideration of relevant internal and external information. Actual results may differ from these estimates.

Revenue Recognition

Revenue Recognition 

We recognize revenue when control of the promised goods is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods.

Our primary performance obligation to our customers is the delivery of flooring products pursuant to purchase orders. Control of the products we sell generally transfers to our customers at the point in time when the goods are shipped. Our standard sales terms are primarily free-on-board shipping point. Our typical payment terms are 30 days and our sales arrangements do not contain any significant financing component for our customers. Our customer arrangements do not generate contract assets or liabilities that are material to the Consolidated Financial Statements.

Each purchase order sets forth the transaction price for the products purchased under that arrangement. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon our customers meeting specified performance criteria, such as a purchasing level over a period of time. We use judgment to estimate the most likely amount of variable consideration at each reporting date.

Costs to obtain a contract are capitalized and amortized over the life of the related contract when the incremental costs directly relate to a specific contract, generates or enhances resources of the company that will be used to satisfy performance of the terms of the contract and the cost are expected to be recovered from the customer. During the fourth quarter of 2020 we capitalized $1.1 million of costs to obtain a contract, related to a single new arrangement, which will be amortized over the three year contractual agreement.

We disaggregate revenue based on customer geography as this category represents the most appropriate depiction of how the nature, timing and uncertainty of revenues and cash flows are impacted by economic factors. See Note 3, Nature of Operations, to the Consolidated Financial Statements for our revenues disaggregated by geography.

Warranties

Warranties - We provide our customers with a product warranty that provides assurance that the products we sell meet standard specifications and are free of defects. We maintain a reserve for claims and related costs based on historical experience and periodically adjusts these provisions to reflect actual experience.

Sales Incentives

Sales Incentives - Sales incentives to customers are reflected as a reduction of net sales.

Shipping and Handling Costs

Shipping and Handling Costs - We treat shipping and handling that occurs after customers obtain control of the products as a fulfillment activity and not as a promised service. Shipping and handling costs are reflected as a component of cost of goods sold.

Advertising Costs

Advertising Costs We recognize advertising expenses as they are incurred.

Pension and Postretirement Benefits

Pension and Postretirement Benefits

We have benefit plans that provide for pension, medical and life insurance benefits to certain eligible employees when they retire from active service. The cost of plan amendments that provide for benefits already earned by plan participants is amortized over the expected future working lifetime or the life expectancy of plan participants. A market-related value of plan assets methodology is utilized in the calculation of expected return on assets. The methodology recognizes gains and losses on long duration bonds immediately, while gains and losses on other assets are recognized in the calculation over a five-year period. We use a December 31 measurement date for our pension and postretirement benefit plans. See Note 15, Pension and Other Postretirement Benefit Programs, to the Consolidated Financial Statements for additional information.

Taxes

Taxes

The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes to reflect the expected future tax consequences of events recognized in the Consolidated Financial Statements. Deferred income tax assets and liabilities are recognized by applying enacted tax rates to temporary differences that exist as of the balance sheet date which result from differences in the timing of reported taxable income between tax and financial reporting.

We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability and foreign source income, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment.

We recognize the tax benefits of an uncertain tax position only if those benefits are more likely than not to be sustained based on existing tax law. Additionally, we establish a reserve for tax positions that are more likely than not to be sustained based on existing tax law, but uncertain in the ultimate benefit to be sustained upon examination by the relevant taxing authorities.  Unrecognized tax benefits are subsequently recognized at the time the more likely than not recognition threshold is met, the tax matter is effectively settled or the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired, whichever is earlier.

We account for all interest and penalties on uncertain income tax positions as income tax expense.

See Note 6, Income Taxes, to the Consolidated Financial Statements for additional information.

Earnings per Share

Earnings Per ShareBasic earnings per share is computed by dividing the earnings attributable to common shares by the sum of the weighted average number of shares of common stock outstanding during the period and the weighted average number of stock-based awards that have vested but not yet been issued during the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings. See Note 8, Earnings Per Share of Common Stock, to the Consolidated Financial Statements for additional information.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and short-term investments that have maturities of three months or less when purchased. The Company has no restricted cash.

Receivables

Receivables

We sell the vast majority of our products to select, pre-approved customers using customary trade terms that allow for payment in the future. Customer trade receivables and miscellaneous receivables, net of allowances for current expected credit losses, customer credits and warranties are reported in accounts and notes receivable on a net basis. Cash flows from the collection of receivables are classified as operating cash flows on the Consolidated Statements of Cash Flows.

We establish credit-worthiness prior to extending credit. We estimate the net of allowances for current expected credit losses of receivables each period. This estimate is based upon the current and forecasted economic conditions as well as an analysis of prior credit losses by receivable type. Account balances are charged off against the allowance when the potential for recovery is considered remote. We do not have any off-balance-sheet credit exposure related to our customers.

Inventories

Inventories

U.S. inventories are valued at the lower of cost or market and cost is determined using the last-in, first-out ("LIFO") method of accounting. Non-U.S. inventories are valued at the lower of cost or net realizable value and cost is determined using the first-in, first-out ("FIFO") method of accounting. Additionally, inventory balances are adjusted for estimated obsolete or unmarketable inventory equal to the difference between the cost of inventory and its net realizable value or estimated market value, as applicable. See Note 10, Inventories, to the Consolidated Financial Statements for additional information.

Property Plant and Equipment

Property Plant and Equipment

Property, plant and equipment is recorded at cost reduced by accumulated depreciation. Depreciation expense is recognized on a straight-line basis over assets’ estimated useful lives. Machinery and equipment includes manufacturing equipment (depreciated over 3 to 15 years), computer equipment (depreciated over 3 to 5 years) and office furniture and equipment (depreciated over 5 to 7 years). Within manufacturing equipment, assets that are subject to accelerated obsolescence or wear, such as tooling and engraving equipment, are depreciated over shorter periods (3 to 7 years). Heavy production equipment, such as conveyors, kilns and mixers, are depreciated over longer periods (10 to 15 years). Buildings are depreciated over 15 to 30 years, depending on factors such as type of construction and use. Computer software is amortized over 3 to 7 years.

Property, plant and equipment is tested for impairment when indicators of impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by an asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.

Intangible Assets

Intangible Assets

Our indefinite-lived intangible assets are primarily trademarks which are integral to our corporate identity and expected to contribute indefinitely to our corporate cash flows. We conduct our annual impairment test for indefinite-lived intangible assets during the fourth quarter and we conduct interim impairment tests if indicators of potential impairment exist.

An impairment is recognized if the carrying amount of the asset exceeds its fair value. We first perform a qualitative assessment to determine if it is necessary to perform a quantitative impairment test. If a quantitative impairment test is deemed necessary, the method used to determine the fair value of our indefinite-lived intangible assets is the relief-from-royalty method. The principal assumptions used in our application of this method are revenue growth rate, discount rate and royalty rate. Revenue growth rates are derived from those used in our operating plan and strategic planning processes. The discount rate assumption is calculated based upon an estimated weighted average cost of capital, which we believe reflects the overall level of inherent risk and the rate of return a market participant would expect to achieve. The royalty rate assumption represents the estimated contribution of the intangible asset to overall profits. The method used for valuing our indefinite-lived intangible assets did not change from prior periods.

Our long-lived intangible assets are primarily contractual arrangements (amortized over 5 years), which includes non-compete agreements, and intellectual property (amortized over 2 to 15 years), which includes developed technology and patents. We review long-lived intangible assets for impairment if indicators of potential impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by the asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.

Foreign Currency Transactions

Foreign Currency Transactions

For our subsidiaries with non-U.S. dollar functional currency, assets and liabilities are translated at period-end exchange rates. Revenues and expenses are translated at exchange rates effective during each month. Foreign currency translation gains or losses are included as a component of accumulated other comprehensive (loss) ("AOCI") within equity. Gains or losses on foreign currency transactions are recognized through net income (loss).

Stock-Based Employee Compensation

Stock-Based Employee Compensation

We issue stock-based compensation to certain employees and non-employee directors in different forms, including various types of performance-based share compensation including performance-based stock awards ("PSAs"), performance-based stock units ("PSUs"), performance-based restricted stock units ("PBRSUs"); and restricted stock units ("RSUs"). We record stock-based compensation expense based on an estimated grant-date fair value. The expense is reflected as a component of selling, general and administrative (“SG&A”) expenses on our Consolidated Statements of Operations. Stock-based compensation expense includes an estimate for forfeitures and anticipated achievement levels and is generally recognized on a straight-line basis over the vesting period for the entire award. See Note 4, Stock-based Compensation, to the Consolidated Financial Statements for additional information.

Leases

We lease certain real estate (warehouse and office space), vehicles and equipment. For leases with an initial term of one year or less we recognize lease expense for these leases on a straight-line basis over the lease term. Leases with an initial term of one year or more are recorded on the balance sheet. We consider all payments fixed unless there is a material impact to the balance sheet at any given time during the lease period.

We determine if a contract is a lease at inception. Operating leases are included in operating lease assets, accounts payable and accrued expenses and noncurrent operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, current installments of long-term debt and long-term debt in our consolidated balance sheets.

Right-of-use ("ROU") assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. We update these rates annually. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain with a compelling economic reason that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We have elected to combine lease and non-lease components as a single component and account for it as a lease for all asset classes with the exception of land and non-operating buildings. Lease and non-lease components of land and non-operating buildings are generally accounted for separately.

We have elected to use a portfolio approach to determine the discount rate and defined portfolio based on the geographic location of the asset by country and duration of the lease.

See Note 5, Leases, to the Consolidated Financial Statements for additional information.

Recently Adopted Accounting Standards and Recently Issued Accounting Standards

Recently Adopted Accounting Standards

On January 1, 2020, we adopted Accounting Standards Update ("ASU") 2016-13, "Measurement of Credit Losses on Financial Instruments." The guidance requires immediate recognition of estimated credit losses that are expected to occur over the remaining life of many financial assets. The most notable impact of this ASU related to our processes around the assessment of the adequacy of our allowance for doubtful accounts on trade account receivables. We adopted using the modified retrospective transition method. The adoption of the standard did not have a material impact on our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-13, "Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement." The guidance eliminates, adds and modifies certain disclosure requirements. Adoption of the standard did not have an impact our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-14, "Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans." The guidance changes the disclosure requirements by eliminating certain disclosures that are no longer considered cost beneficial and added new ones that are considered pertinent. Adoption of the standard did not have an impact our financial condition, results of operations or cash flows.

On January 1, 2020, we adopted ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The guidance aligns the requirements for capitalizing implementation costs in a cloud computing arrangement service contract with the requirements for capitalizing implementation costs incurred for an internal use software license. Capitalized implementation costs should be amortized over the term of the service agreement on a straight line basis and should be assessed for impairment in a manner similar to long-lived assets. We adopted using the prospective transition method. This standard did not have a material impact on our financial condition, results of operations or cash flows.

On January 1, 2019, we adopted ASU 2016-02, "Leases." The guidance, and subsequent amendments issued, requires a lessee to recognize the assets and liabilities that arise from a lease agreement. Specifically, this new guidance requires lessees to recognize a liability to make lease payments and a ROU asset representing its right to use the underlying asset for the lease term, with limited exceptions. Adoption of the new standard resulted in the recording of lease assets and lease liabilities of $9.2 million as of January 1, 2019 and the adoption is not expected to have a significant impact on the Company's Consolidated Financial Statements.

On January 1, 2018, we adopted ASU 2014-09, "Revenue from Contracts with Customers" and all the related amendments. The impact of the standard is limited to our accounting for warranties and returns. We adopted the standard using the modified retrospective transition method and we recorded a cumulative catch up adjustment as of January 1, 2018 to increase accumulated deficit in the amount of $4.1 million, increase prepaid expenses and other current assets by $0.4 million and decrease accounts receivable, net by $4.5 million. The adoption of the standard did not have a material impact on our results of operations or cash flows, but did result in new disclosures.

Recently Issued Accounting Standards

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" This new standard eliminates certain exceptions in ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, guidance on accounting for franchise taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020. We will adopt ASU 2019-12 as of January 1, 2021 and the adoption is not expected to have a significant impact on our consolidated financial statements.
