ITEM 1. Business

GENERAL

We are a premier manufacturer and supplier of bleached paperboard and consumer and parent roll tissue. We supply bleached paperboard to quality-conscious printers and packaging converters, and offer services that include custom sheeting, slitting and cutting. We supply private label tissue to major retailers and wholesale distributors, including grocery, club, mass merchants and discount stores.

STRATEGY

Our long-term strategy is to expand our business to meet the needs of our customers and optimize the profitability of both our Pulp and Paperboard and our Consumer Products segments. In the near-term, our capital allocation focus is on sustaining our asset base, reducing debt and costs to drive enhanced business performance in both segments of our company.

ORGANIZATION

Our business is organized into two operating segments: Pulp and Paperboard and Consumer Products. Sales for these segments for the last three years are included in the table below:

	Year Ended December 31,						Increase (decrease)
(In millions)	2021		2020		2019		2021-2020		2020-2019
Pulp and Paperboard	$	946.0	$	877.1	$	885.4	7.8	%	(0.9)	%
Consumer Products	835.0		1,018.5		902.5		(18.0)	%	12.9	%
Eliminations	(8.4)		(27.0)		(26.3)		(69.0)	%	2.4	%
	$	1,772.6	$	1,868.6	$	1,761.5	(5.1)	%	6.1	%

Pulp and Paperboard Segment

Our Pulp and Paperboard segment markets and manufactures bleached paperboard for the high-end segment of the packaging industry and is a leading producer of Solid Bleached Sulfate (SBS) paperboard. This segment produces hardwood and softwood pulp, which is primarily used as the basis for our paperboard products or transferred to our Consumer Products segment. Minor amounts of pulp are sold to outside customers.

Our Pulp and Paperboard Business

We believe we are one of the five largest producers of bleached paperboard in North America with approximately 14% of the available U.S. production capacity in 2021. We also provide custom sheeting, slitting and cutting of paperboard products.

Our paperboard production consists of folding carton, liquid packaging, cup and plate products, blister and carded packaging, top sheet and commercial printing grades and softwood pulp. In addition to virgin fiber products, we also offer several grades of folding carton and cup stock with post-consumer fiber content.

Folding carton board used in pharmaceuticals, cosmetics and other premium packaging, such as those that incorporate foil and holographic lamination, accounts for the largest portion of our total paperboard sales. We focus on high-end folding carton applications where the heightened product quality requirements provide for differentiation among suppliers, generally resulting in margins that are more attractive than less demanding packaging applications.

Our liquid packaging paperboard is known for its cleanliness and printability, and is engineered for long-lived performance due to its three-ply, softwood construction. Our reputation for producing liquid packaging meets the most demanding standards for paperboard quality and cleanliness, where consumers have a particular tendency to associate blemish-free, vibrant packaging with the cleanliness, quality and freshness of the liquids contained inside.

With the exception of our capability to supply just-in-time sheeting and narrow rolls, we do not produce converted paperboard end-products, so we are not simultaneously a supplier of and a competitor to our customers in key market segments, notably folding carton and cup. Of the five largest SBS paperboard producers in the United States, we are the only producer that does not convert SBS paperboard into folding cartons, cups, plates or liquid packaging end-use products. We position our independent status to attract a diverse group of loyal customers because when there is increased market demand for paperboard, we do not divert our production to internal uses.

3

We can convert paperboard parent rolls to flat sheets and narrow rolls, which expands our in-market service capabilities and allows us to support small and mid-sized folding carton converters that buy sheeted paperboard to convert into packaging end-products. Providing a service platform in this way expands the key folding carton segment of our business and does not compete with our customers in other key market segments.

We utilize various methods for the sale and distribution of our paperboard. The majority of our paperboard is sold to packaging converters in North America through sales managers located throughout the United States, with a smaller percentage channeled through distribution to commercial printers. We directly sell sheeted paperboard products to folding carton converters, merchants and commercial printers. Our principal methods of competing are product quality, customer service and price.

Consumer Products Segment

Our Consumer Products segment sells and produces a complete line of at-home tissue products. Our integrated manufacturing and converting operations and geographic footprint enable us to deliver a broad range of cost-competitive products with brand equivalent quality to our customers. We also sell minor amounts of parent rolls. Prior to the closure of our Neenah, Wisconsin facility in July 2021, we sold minor amounts of away from home (AFH) products and performed limited contract manufacturing.

Our Consumer Products Business

We believe that we are the only U.S. consumer tissue manufacturer that solely produces a full line of quality private label tissue products for large retail trade channels with a national footprint. We believe we are able to offer products that match the quality of leading national brands, but generally at lower prices. We utilize independent companies to routinely test our product quality.

In bath tissue, the majority of our sales are high quality two-ply ultra and premium products. In paper towels, we produce and sell ultra quality towels as well as premium and value towels. In the facial category, we sell ultra-lotion three-ply and a complete line of two-ply premium products, as well as value facial tissue. In napkins, we manufacture ultra two- and three-ply dinner napkins, as well as premium and value one-ply luncheon napkins. Value grade products utilizing recycled fiber are also produced for customers who wish to further diversify their product portfolio. We compete primarily in the at-home portion of the U.S. tissue market. We believe we accounted for 6% of the overall U.S. at-home market in 2021, including branded and private branded products.

We sell tissue products through our own sales force and compete based on product quality, customer service and price. We deliver customer-focused business solutions by assisting in managing product assortment, category management and pricing and promotion optimization.

INPUT COSTS

During 2021, we saw significant increases in costs across our businesses. Based upon current projections as of the date of this report, we anticipate $90 to $100 million of inflation in raw materials, freight and energy for the year ended December 31, 2022.

Raw Materials

Wood fiber is our principal raw material, which consists of chips, sawdust and logs. We own and operate a wood chipping facility which we believe bolsters our wood fiber position and provides short-term and long-term cost savings.

Additionally, we procure a portion of our pulp requirements. Annually, we purchase approximately 310,000 short tons of pulp, the majority of which is bleached hardwood pulp, on the open market through long-term contracts or market transactions. Our Pulp and Paperboard segment purchases approximately 55,000 short tons and our Consumer Products segment purchases approximately 255,000 short tons. The remaining pulp needs for our Consumer Products segment are supplied internally by our Pulp and Paperboard segment.

In addition to wood fiber, we utilize a significant amount of chemicals in the production of pulp and paper, including caustic, polyethylene, starch, sodium chlorate, latex and specialty process paper chemicals. A portion of the chemicals used in our manufacturing processes, particularly in the pulp-making process, are petroleum-based or are impacted by petroleum prices.

4

Transportation

Transportation is a significant cost input for our business. Fuel prices, mileage driven and line-haul rates impact our transportation costs for delivery of raw materials to our manufacturing facilities, internal inventory transfers and delivery of our finished products to customers.

Energy

We consume substantial amounts of energy, such as electricity, hog fuel, steam and natural gas. We purchase a significant portion of our natural gas and electricity under supply contracts, most of which are between a specific facility and a specific local provider. Under most of these contracts, the providers have agreed to provide us with our requirements for a particular type of energy at a specific facility. Most of these contracts have pricing mechanisms that adjust or set prices based on current market conditions.

SEASONALITY

Our Consumer Products segment can experience a decrease in shipments during the fourth quarter as a result of retail brand holiday promotions. In addition, customer buying patterns for our paperboard generally result in lower sales for certain grades of our Pulp and Paperboard segment during the first and fourth quarters, compared to the second and third quarters of a given year.

GOVERNMENTAL

For a discussion of the uncertainties and business risks associated with the environmental regulations, see Part I, Item 1A, "Risk Factors—Risks Related to Our Business Operations and the Markets in Which We Operate — We are subject to significant environmental regulations and environmental compliance expenditures, which could increase our costs and subject us to liabilities" including information regarding environmental matters under Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this report, and which is incorporated herein by reference.

HUMAN CAPITAL

Our core values of Commitment, Collaboration, Communication, Courage, and Character are the foundation that define our culture and guide our operations to ensure that we protect, develop, and support our most critical stakeholders – our employees, customers, and communities. We apply these core values throughout our organization with key focus areas of safety and human capital management (including diversity, equity, and inclusion) as discussed below.

Safety

The health and safety of our employees is our highest priority. We aspire to achieve zero workplace injuries and provide a safe, open, and accountable work environment for our employees. We have a dedicated Environmental, Health and Safety (EH&S) team that is tasked with promoting safe working practices, monitoring incidents, and working to reduce risks to our employees. Our EH&S team compiles and publishes regular safety results and leverages this information to implement enhanced safety procedures and training across our operations. We provide several channels for all employees to speak up, ask for guidance, and report concerns related to ethics or safety violations. We address employee concerns and take appropriate actions that uphold our core values.

Our priority throughout the COVID-19 pandemic continues to be protecting the health and safety of our employees while maintaining business continuity. We have established safety protocols that meet or exceed recommendations issued by federal, state, and local governments. A vast majority of our office workers continue to telecommute. Within our production and office areas safety protocols include face covering and physical distance requirements, enhanced cleaning and beginning in September 2021, employees working in our facilities are tested weekly for COVID-19. We actively encourage our employees to consider COVID-19 vaccination and have established incentive programs to further promote immunization.

Human Capital Management

Our approximately 3,000 employees are instrumental to delivering on our commitments to our customers and securing long term success for our organization. We actively work to attract and retain the best-qualified talent by offering

5

competitive benefits, including market-competitive compensation, healthcare, paid time off, parental leave, retirement benefits, tuition assistance, employee skills development and leadership development. We have deployed training and development programs across our organization to invest in the professional growth of our people.

We believe that a sustained commitment to diversity, equity and inclusion makes us a stronger organization. We are dedicated to fostering and sustaining an environment where our teammates are valued for their unique backgrounds, knowledge, skills, and experiences. During 2020, we launched a steering committee and in 2021, we began execution of a multiple year diversity, equity and inclusion plan dedicated to prioritizing and furthering our efforts.

As of December 31, 2021, approximately 42% of our employees are covered under collective bargaining agreements. Unions represent hourly employees at two of our manufacturing sites. For a discussion of the uncertainties and business risks associated with employee relations, see Part I, Item 1A, "Risk Factors—Risks Related to Our Business Operations and the Markets in Which We Operate — Our business and financial performance may be harmed by future labor disruptions."

ITEM 1A. Risk Factors

Our business, financial condition, results of operations and liquidity are subject to various risks and uncertainties, including those described below, and as a result, the trading price of our common stock could decline.

RISKS RELATED TO OUR BUSINESS OPERATIONS AND THE MARKETS IN WHICH WE OPERATE

The COVID-19 pandemic may adversely affect our operations and financial condition.

The COVID-19 pandemic has had, and another pandemic in the future could have, repercussions across regional and global economies and financial markets. The outbreak of COVID-19 has significantly adversely impacted global economic activity and has contributed to significant volatility in financial markets.

In the domestic paperboard and tissue markets in 2021, the COVID-19 pandemic resulted in significant variability. Following the significant increase in demand for tissue products due to at-home consumer purchasing behavior during 2020, we experienced a significant decrease in demand early in 2021 followed by upticks in demand in the second half of the year. Demand for paperboard products has also been affected by the COVID-19 pandemic, with increases in some end-market segments like food and healthcare packaging and decreases in food service and commercial print.

Our business, the businesses of our customers and the businesses of our suppliers could be materially and adversely affected by the impact and risks of the pandemic. Such risks include, but are not limited to, the following:

•the interruption of our distribution system or delays in the delivery of our products;

•temporary or long-term disruption in our supply chains;

•the complete or partial closure of one or more of our manufacturing facilities;

•the loss of our management team and employee base that possess unique technical skills for the execution of our business plan;

•limitations on our ability to operate our business as a result of any federal, state or local regulations;

•disruptions to international trade, or further restrictions or prohibitions on international travel, on which we rely to make our products (for example, an interruption in eucalyptus pulp from Brazil or lack of availability for spare parts or technical support from European suppliers of our production and converting equipment);

•variability in demand for our products, including inability to meet a sharp increase in demand, a decrease in demand for our products as a result of a prolonged economic downturn or global recession (for example, during previous, extreme recessionary periods in the U.S., we experienced significant declines in demand for our paperboard used in folding carton, cup and liquid packaging applications);

•volatility related to pension plan assets (for example, we may need to make additional contributions to address an increase in obligations and/or a loss in plan assets as a result of the combination of declining market interest rates and/or past or future plan asset investment losses);

•significant disruption of global financial markets, which could have a negative impact on our ability to access capital in the future;

•a decline in our ability to collect on accounts receivable, which could materially affect our liquidity;

•bankruptcy of customers that leads to a decrease in demand for our products;

•and an interruption in processing or an inability to process accounts payable by our third-party processor, which could result in our suppliers and vendors withholding supplies or services.

Increases in tissue supply, particularly in the premium and ultra categories, could adversely affect our operating results and financial condition.

Over the past few years, several new or refurbished premium and ultra-quality tissue paper machines and converting assets have been completed or announced by us and by our competitors, including private label competitors, which has resulted and will continue to result in a substantial increase in the supply of premium and ultra-quality tissue in the North American market. Additionally, several new or refurbished conventional tissue machines have been installed or announced, including as a result of foreign competitors increasing their presence and operations in North America. As a result of increased tissue demand due to the COVID-19 pandemic in 2020, foreign tissue manufacturers increased exports into the U.S. market, regional tissue manufacturers increased their production, and some away-from-home tissue

7

manufacturers re-purposed their products to the at-home market, all of which increased tissue supply. We believe that increasing tissue capacity, together with intensifying competition experienced by our retail customers, has made it difficult for us to pass through to our customers the significant increases in input costs we have experienced in the last several years. If demand for tissue products in the North American market does not increase or consumer purchasing of premium and ultra-quality tissue do not increase commensurate with the increased capacity, the increase in supply of ultra-quality tissue products could have a material adverse effect on the price of premium and ultra-quality tissue products. In addition, increased supply of premium and ultra-quality tissue may adversely affect the market prices and margins for such tissue and result in the displacement of demand for conventional tissue, which could adversely affect the market price for conventional tissue products, which will continue to represent a significant portion of our total production for the foreseeable future.

The loss of, or a significant reduction in, orders from, or changes in prices in regard to, any of our large customers could adversely affect our operating results and financial condition.

We derive a substantial amount of revenues from a concentrated group of customers. Our top 10 customers accounted for 46% of sales in 2021. If we lose any of these customers or a substantial portion of their business or if the terms of our relationship with any of them becomes less favorable to us, our net sales would decline, which would harm our results of operations and financial condition. In 2022, we have some large tissue agreements up for renewal. We have experienced increased price and promotion competition in our consumer products business, and this competition has decreased our gross margins and adversely affected our financial condition.

We generally do not have long-term contracts with many of our customers that ensure a continuing level of business from them. In addition, our agreements with our customers, including our largest customers, are not exclusive and generally do not contain minimum volume purchase commitments. Our relationship with our largest and most important customers will depend on our ability to continue to meet their needs for quality products and services at competitive prices. Some of our customers have the capability to produce the parent rolls or products that they purchase from us. If we lose one or more of our large customers or if we experience a significant decline in the level of purchases by any of them, we may not be able to quickly replace the lost business volume and our operating results and business could be harmed.

The expansion of our tissue business through the integration of our facilities and production capacity may not proceed as anticipated.

We continue to integrate the newest paper machine and converting facilities at our Shelby, North Carolina site within our national tissue network, including the development and production of premium and ultra-quality tissue products. The ongoing integration entails numerous risks, including diverting management's attention from other business concerns, difficulties in the operations integration and product development, and uncertainties regarding the existence of sufficient customer demand for the tissue produced by our integrated network. Any of these risks if realized, could have a material adverse effect on our business, financial condition, results of operations and liquidity.

We depend on external sources of wood pulp and wood fiber for a significant portion of our tissue production, which subjects our business and results of operations to potentially significant fluctuations in the price of market pulp and wood fiber.

Our Consumer Products segment sources a significant portion of its wood pulp requirements from external suppliers, which exposes us to price fluctuation. For 2021, we sourced 60% of our Consumer Product segment pulp requirements (or 30% overall) of our pulp from external sources. Pulp prices can, and have, changed significantly from one period to the next. The volatility of pulp prices can adversely affect our earnings if we are unable to pass cost increases on to our customers or if the timing of any price increases for our products significantly trails the increases in pulp prices.

Wood fiber is the principal raw material used to create wood pulp, which in turn is used to manufacture our pulp and paperboard products and consumer products. Wood fiber pricing is subject to regional market influences, and our cost of wood fiber may increase in the areas our pulp and paperboard facilities are located due to market shifts in those regions. For example, much of the wood fiber we use in our pulp manufacturing process in Lewiston, Idaho, is the by-product of sawmill operations. As a result, the price of these residual wood fibers is affected by operating levels in both the pulp and paper and lumber industries. During the past decade in the western U.S. many sawmills have closed or curtailed operations or their operations have been consolidated. Further, the expansion of operations and production of other paper mills and wood pellet manufacturers in the Inland Northwest region of the United States has increased the demand and price for wood fiber. Additionally, the ability of paper and wood pellet mills in British Columbia to acquire wood fiber from the U.S. Inland Northwest region with limited to no reciprocal ability by U.S. mills to acquire wood fiber from

8

British Columbia, reduces the supply of, and increases the costs, for wood fiber. The price of wood fiber in the Pacific Northwest is expected to remain volatile.

The primary source for wood fiber is timber, the availability of which may be limited by adverse weather, fire, insect infestation, disease, ice storms, windstorms, flooding and other natural and man-made causes, thereby reducing supply and increasing prices. Our Arkansas pulp and paperboard facility relies on whole log chips for a significant portion of its wood fiber.

The effects on market prices for wood fiber resulting from various governmental programs involving tax credits or payments related to biomass and other renewable energy projects or from environmental litigation or regulation are uncertain and could result in a reduction in the supply of wood fiber available for our pulp and paperboard manufacturing operations. Additionally, wood pellet facilities or fluff pulp facilities, can increase demand and prices for wood fiber. If we and our pulp suppliers are unable to obtain wood fiber at favorable prices or at all, our costs will increase and our operations and financial results may be harmed.

Disruptions in transportation services or increases in our transportation costs could have a material adverse effect on our business.

Our business is dependent on transportation services to deliver our products to our customers and to deliver raw materials to us as well as for intercompany shipments of parent rolls. Shipments of products and raw materials may be delayed or disrupted due to weather conditions, labor shortages or strikes, regulatory actions or other events. If our transportation providers are unavailable or fail to deliver our products in a timely manner, we may incur increased costs and we may be unable to manufacture and deliver our products on a timely basis. In 2021, we experienced both difficulties in procuring sufficient transportation for intercompany and external shipments as well as significant increases in transportation costs due to a number of factors.

The costs of these transportation services are also affected by geopolitical, economic and weather-related events. We have not been able in the past, and may not be able in the future, to pass along part or all of any fuel price increases to customers. If we are unable to increase our prices because of increased fuel or transportation costs, our gross margins may be materially adversely affected.

We rely on a limited number of third-party suppliers and vendors required for the production of our products and our operations.

Our dependence on a limited number of third-party suppliers, and the challenges we may face in obtaining adequate supplies of raw materials, involve several risks, including limited control over pricing, availability, quality and delivery schedules. Limitations on the availability of, and subsequent increases in, the costs of raw materials, could have an adverse effect on our financial results. We cannot be certain that our current suppliers will continue to provide us with the quantities of these raw materials that we require or will continue to satisfy our anticipated specifications and quality requirements. Any supply interruption in limited raw materials could materially harm our ability to manufacture our products until a new source of supply, if any, could be identified and qualified. Although we believe there are other suppliers of these raw materials, we may be unable to find a sufficient alternative supply channel in a reasonable time or on commercially reasonable terms.

We also depend on a limited number of third-party vendors for certain of our operating equipment and spare parts. Any performance failure on the part of our suppliers or vendors could interrupt production of our products, which would have a material adverse effect on our business.

The cost of chemicals and energy needed for our manufacturing processes significantly affects our results of operations and cash flows.

We use a variety of chemicals in our manufacturing processes, including petroleum-based polyethylene and certain petroleum-based latex chemicals. Prices for these chemicals have been and are expected to remain volatile. In addition, chemical suppliers that use petroleum-based products in the manufacture of their chemicals may, due to supply shortages and cost increases, ration the amount of chemicals available to us, and therefore we may not be able to obtain at favorable prices the chemicals we need to operate our business, if we are able to obtain them at all.

Our manufacturing operations also utilize large amounts of electricity and natural gas. Energy prices have fluctuated widely over the past decade, which in turn affects our operational costs. We purchase on the open market a substantial portion of the natural gas necessary to produce our products, and, as a result, the price and other terms of those purchases are subject to change based on factors such as worldwide supply and demand, geopolitical events, government regulation, weather, interruptions in pipeline and other delivery systems and natural disasters. Our energy costs in future

9

periods will depend principally on our ability to produce a substantial portion of our electricity needs internally, on changes in market prices for natural gas and on reducing energy usage. Any significant energy shortage or significant increase in our energy costs in circumstances where we cannot raise the price of our products could have a material adverse effect on our results of operations. Any disruption in the supply of energy could also affect our ability to meet customer demand in a timely manner and could harm our reputation and our business.

Competitors' branded products and private label products could have an adverse effect on our financial results.

Our tissue products compete with well-known, branded products, as well as other private label products. Our business may be harmed by new product offerings by competitors, the effects of consolidation within retailer and distribution channels and price competition from companies that may have greater financial resources than we do. If we are unable to offer our existing customers, or new customers, tissue products comparable to branded products or other companies' private label products in terms of quality, customer service and/or price, we may lose business or we may not be able to grow our existing business, and we may be forced to sell lower-margin products, all of which could negatively affect our financial condition and results of operations.

Larger competitors have operational and other advantages over our operations.

The markets for our products are highly competitive, and companies that have substantially greater financial resources compete with us in each market. Some of our competitors have advantages over us, including lower raw material and labor costs and better access to the inputs of our products.

Our Consumer Products business faces competition from companies that produce the same type of products that we produce or that produce alternative products that customers may use instead of our products. Our Consumer Products business competes with the branded tissue products producers, such as Procter & Gamble, and branded label producers who manufacture branded and private label products, such as Georgia-Pacific and Kimberly-Clark. These companies are far larger than us, have more sales, marketing and research and development resources than we do, and enjoy significant cost advantages due to economies of scale. In addition, because of their size and resources, these companies may foresee market trends more accurately than we do and develop new technologies that render our products less attractive or obsolete.

Our ability to successfully compete in the pulp and paperboard industry is influenced by a number of factors, including manufacturing capacity, general economic conditions and the availability and demand for paperboard substitutes. Our Pulp and Paperboard business competes with WestRock, Georgia-Pacific, Graphic Packaging, Pactiv Evergreen and other international producers, most of whom are much larger than us. Any increase in manufacturing capacity by any of these or other producers could result in overcapacity in the pulp and paperboard industry, which could cause downward pressure on pricing. For example, a European company recently announced the acquisition of a U.S. based printing and writing grade company, with the intention to convert two paper machines to produce paperboard for the North American market. Increased production by foreign manufacturers may result in increased competition in the North American paperboard markets from direct sales by foreign competitors into these markets or increased competition in the United States as domestic manufacturers seek increased U.S. sales to offset displaced overseas sales caused by increased sales by foreign suppliers into Asia and European markets. Furthermore, customers could choose to use types of paperboard that we do not produce or could rely on alternative materials, such as plastic, for their products. An increased supply of or demand for any of these products could cause us to lower our prices or lose sales to competitors, either of which could have a material adverse effect on our results of operations and cash flows.

Changing retail purchasing patterns have increased the need to increase operating efficiencies and diversify our customer base and sales channels.

We have historically sold a majority of our consumer tissue products through retail grocery stores. These and other traditional retail outlets are facing increasingly intense competition from supercenters, club stores, wholesale grocers, drug, dollar, variety and specialty stores. We also face increasingly intense competition from competitors who have incorporated the internet as a direct-to-consumer channel and internet-only providers that sell tissue and other grocery products. The intense competition faced by our customers has resulted in increased efforts by them to reduce costs from suppliers like us and requires that we become more cost efficient to maintain our market share and profitability. The changing retail landscape also requires that we develop and maintain relationships with a wider variety of retailers and retail channels to succeed in this dynamic environment, which can decrease our supply network efficiency and increase our costs.

Consolidation in the North American paperboard and converting industry may adversely affect our business.

10

The ongoing consolidation of paperboard and paperboard converting businesses, including through the acquisition and integration of such converting businesses by larger competitors of ours, could result in a loss of customers and sales in our pulp and paperboard business. A loss of paperboard customers or sales as a result of consolidations and integrations could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We incur significant expenses to maintain our manufacturing equipment and any interruption in the operations of our facilities may harm our operating performance.

We regularly incur significant expenses to maintain our manufacturing equipment and facilities. The machines and equipment that we use to produce our products are complex, interdependent, have many parts and some are run on a continuous basis. We must perform routine maintenance on our equipment and will have to periodically replace a variety of parts such as motors, pumps, pipes and electrical parts. In addition, our pulp and paperboard facilities require periodic shutdowns to perform major maintenance. These scheduled shutdowns of facilities result in decreased sales and increased costs in the periods in which they occur and could result in unexpected operational issues in future periods as a result of changes to equipment and operational and mechanical processes made during the shutdown period.

Unexpected production disruptions could cause us to shut down or curtail operations at any of our facilities. Disruptions could occur due to any number of circumstances, including prolonged power outages, mechanical or process failures, shortages of raw materials, natural catastrophes, disruptions in the availability of transportation, labor disputes,cyber attacks and malware, terrorism, changes in or non-compliance with environmental or safety laws, and the lack of availability of services from any of our facilities' key suppliers. For example, in 2021 we had a fire at our Las Vegas facility, and in both 2020 and 2021 severe weather events resulted in the shutdown or curtailment of operations at our Arkansas mill. Any facility shutdowns may be followed by prolonged startup periods, regardless of the reason for the shutdown. Those startup periods could range from several days to several weeks, depending on the reason for the shutdown and other factors. Any prolonged disruption in operations at any of our facilities could cause significant lost production, which would have a material adverse effect on our results of operations.

Our business and financial performance may be harmed by future labor disruptions.

As of December 31, 2021, approximately 42% of our full-time employees were represented by unions under collective bargaining agreements. As these agreements expire, we may not be able to negotiate extensions or replacement agreements on terms acceptable to us. Any failure to reach an agreement with one of the unions may result in strikes, lockouts, work slowdowns, stoppages or other labor actions, any of which could have a material adverse effect on our operations and financial results.

Cyclical industry conditions have in the past affected and may continue to adversely affect the operating results and cash flows of our pulp and paperboard business.

Our Pulp and Paperboard business has historically been affected by cyclical market conditions. We may be unable to sustain pricing in the face of weaker demand, and weaker demand may in turn cause us to take production downtime. In addition to lost revenue from lower shipment volumes, production downtime causes unabsorbed fixed manufacturing costs due to lower production levels. Our results of operations and cash flows may be materially adversely affected in a period of prolonged and significant market weakness. We are not able to predict market conditions or our ability to sustain pricing and production levels during periods of weak demand.

We rely on information technology in critical areas of our operations, and a disruption relating to such technology could harm our financial condition.

We use information technology, or IT, systems in various aspects of our operations, including enterprise resource planning, management of inventories, manufacturing, supply chain and customer sales. We have different legacy IT systems that we are continuing to integrate, upgrade and move to the cloud. If one of these systems were to fail or cause operational or reporting interruptions, or if we decide to change these systems or hire outside parties to provide these systems, we may suffer disruptions, which could have a material adverse effect on our manufacturing and sales operation, results of operations and financial condition. In addition, we may underestimate the costs, complexity and time required to develop and implement new systems.

We face cyber-security risks.

Our business operations rely upon secure information technology systems for data capture, processing, storage and reporting. Despite careful security and controls design, implementation and updating, our information technology systems or plant networks could become subject to cyber-attacks. Network, system, application and data breaches could result in operational disruptions or information misappropriation, which could result in lost sales, production

11

interruption, business delays, negative publicity, and could have a material adverse effect on our business, results of operations and financial condition.

We are subject to significant environmental regulation and environmental compliance expenditures, which could increase our costs and subject us to liabilities.

We are subject to various federal, state and foreign environmental laws and regulations concerning, among other things, water discharges, air emissions, hazardous material and waste management and environmental cleanup. Environmental laws and regulations continue to evolve and we may become subject to increasingly stringent environmental standards in the future, particularly under air quality and water quality laws and standards related to climate change issues, such as global warming. In particular, greenhouse gas emissions have increasingly become the subject of political and regulatory focus and this may lead to changes in legislative and regulatory initiatives directed at limiting greenhouse emissions.

Increased regulatory activity at the state, federal and international level is possible regarding climate change as well as other emerging environmental issues associated with our manufacturing sites, such as water quality standards or dam breaching for purposes of aiding salmon recovery in the Pacific Northwest. Such new public policy or compliance with regulations that implement new public policy in these areas might require significant expenditures on our part or even the curtailment of certain of our manufacturing operations.

We are required to comply with environmental laws and the terms and conditions of multiple environmental permits. In particular, the pulp and paper industry in the United States is subject to several performance based rules associated with effluent and air emissions as a result of certain of its manufacturing processes. Federal, state and local laws and regulations require us to routinely obtain authorizations from and comply with the evolving standards of the appropriate governmental authorities, which have considerable discretion over the terms of permits. Failure to comply with environmental laws and permit requirements could result in civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing our operations or requiring us to take corrective measures, install pollution control equipment, or take other remedial actions, such as product recalls or labeling changes. We also may be required to make additional expenditures, which could be significant, relating to environmental matters on an ongoing basis. There can be no assurance that future environmental permits will be granted or that we will be able to maintain and renew existing permits, and the failure to do so could have a material adverse effect on our results of operations, financial condition and cash flows.

We own properties, conduct or have conducted operations at properties, and have assumed indemnity obligations for properties or operations where hazardous materials have been or were used for many years, including during periods before careful management of these materials was required or generally believed to be necessary. Consequently, we will continue to be subject to risks under environmental laws that impose liability for historical releases of hazardous substances and to liability for other potential violations of environmental laws or permits at existing sites or ones for which we have indemnity obligations.

We may be subject to operational and financial climate change risks

Extreme, weather-related events caused by climate change, such as prolonged, extreme high or low temperatures, extreme storms, floods and decreased or curtailed water supplies, could result in physical damage to our facilities and operations. Such events may also result in supply chain disruptions and increased costs. For example, in 2021 extreme weather events resulted in the curtailment of natural gas to, and consequent curtailment of operations at, our Arkansas mill. The ability to harvest the wood fiber used in our manufacturing operations may be limited, and prices could become volatile, because of variations in weather, wildfires, and climate conditions. Damage or disruptions we may incur because of climate-related risks could have a material adverse effect on our manufacturing and sales operations, results of operations and financial condition. In addition, we may underestimate the costs, complexity and time required to develop and implement mitigation efforts to address potential climate change impacts.

Our capital expenditures may not achieve the desired outcomes or may be achieved at a higher cost than anticipated

We regularly make capital expenditures and many of our capital projects are complex, costly, and implemented over an extended period of time. We may experience higher expenditures than anticipated for particular capital projects as well as unanticipated business disruptions, and we may not achieve the desired benefits from a given project, any of which could adversely affect our business, financial condition, results of operations and cash flows. In addition, disputes between us and contractors who are involved with implementing capital projects could lead to time-consuming and costly litigation.

RISK RELATED TO OUR EMPLOYEE PLANS

12

We may be required to pay material amounts under multiemployer pension plans; the plans in which we participate are in “critical and declining” or “critical” financial status and this subjects us to potential liabilities, particularly if we withdraw from a plan.

We contribute to two multiemployer pension plans. The amount of our annual contributions to these plans is negotiated with the union representing our employees covered by the plan. In 2021, we contributed approximately $5.7 million to these plans. If in future years we continue to participate in these plans, we may be required to make increased annual contributions, which would reduce the cash available for business and other needs. The decision whether to continue to participate in these multiemployer plans does not rest solely with us; rather, it is negotiated as part of the collective bargaining agreements with labor unions that participate in these plans. There are risks associated with both continuing to participate in multiemployer plans and with withdrawing from multiemployer plans.

If we were to withdraw partially or completely from a multiemployer plan that is underfunded, we would be liable for a proportionate share of that plan's unfunded vested benefits as required by law. This is called a withdrawal liability.

If we continue to participate in a multiemployer pension plan, the future increases in annual contributions are difficult to predict and largely beyond our control. For example, if any other contributing employer withdraws from a multiemployer plan that is underfunded, and the withdrawing employer cannot satisfy its withdrawal liability, then the proportionate share of the plan’s unfunded vested benefits that would be allocable to us and to the other remaining contributing employers would increase.

One of the multiemployer pension plans to which we contribute, the IAM National Pension Fund, or IAM NPF, elected to be certified to be in “critical status” for the plan year beginning January 1, 2019. If we were to withdraw from IAM NPF, either completely or partially, we would incur a statutory withdrawal liability based on our proportionate share of IAM NPF’s unfunded vested benefits. Based on information available to us, as well as information provided by IAM NPF, and reviewed by our actuarial consultant, we estimate that, as of December 31, 2021, the withdrawal liability payment that we would be required to make to IAM NPF were we to completely withdraw in 2021 would be a single payment of approximately $4.2 million on a pretax basis. If we were deemed to be included in a “mass withdrawal” from IAM NPF, this payment could be greater or result in our making annual payments. We currently have no plans to withdraw from IAM NPF and have not recognized any liability associated with a withdrawal from IAM NPF in our consolidated financial statements.

The other multiemployer pension plan to which we contribute, the PACE Industry Union-Management Pension Fund, or PIUMPF, was certified to be in “critical status” for the plan year beginning January 1, 2010 and continued to be in critical status through the plan year beginning January 1, 2014. For the plan years beginning January 1, 2015 through January 1, 2021, PIUMPF was certified to be in "critical and declining status" under the Multiemployer Pension Reform Act of 2014. The number of employers participating in PIUMPF fell from 135 during 2012 to 44 during 2020 and the ratio of inactive participants to active employees participating in PIUMPF has increased from 3.4 inactive participants per each active employee at the end of 2013 to 17.2 inactive participants per each active employee at the end of 2020. We are the largest contributing employer remaining in PIUMPF.

If we were to withdraw from PIUMPF, either completely or partially, we would incur a statutory withdrawal liability based on our proportionate share of PIUMPF’s unfunded vested benefits. Based on information available to us, as well as information provided by PIUMPF, and reviewed by our actuarial consultant, we estimate that, as of December 31, 2021, the withdrawal liability payments that we would be required to make to PIUMPF were we to completely withdraw in 2021 would be approximately $5.7 million per year on a pretax basis. These payments would continue for 20 years with an estimated present value in excess of $86 million on a pre-tax basis. If we were deemed to be included in a “mass withdrawal” from PIUMPF, these payments could continue indefinitely.

The American Recovery Plan Act, or ARPA, includes provisions to provide financial relief to financially troubled multiemployer pension plans. PIUMPF meets the qualifications under ARPA to be eligible for substantial financial relief in an amount intended to allow it to remain solvent until at least 2051. Under the interim final Pension Benefit Guarantee Corporation, or PBGC, rules promulgated under ARPA, it does not appear likely that IAM NPF would satisfy the qualifications to be eligible for funding under ARPA. Under the interim PBGC rules, it does not appear likely that the legislation would reduce the amount of the statutory withdrawal liability we would incur if we were to withdraw from PIUMPF. We are continuing to assess the impact of the legislation and are awaiting the final PBGC rules that will finalize guidelines and procedures for pension plans to apply for funding. We expect PIUMPF will be eligible to apply in early 2023, although this timing may change if the PBGC makes changes to the application process.

Were we voluntarily to withdraw from PIUMPF in 2022 or later, we could be subject to substantial payments in addition

13

to the withdrawal liability payments described above. As a plan in critical and declining status, PIUMPF has adopted a rehabilitation plan. That plan purports to require a withdrawing employer to make an additional, lump-sum payment - above and beyond the statutory withdrawal liability - based on PIUMPF’s accumulated funding deficiency, or AFD. We do not believe PIUMPF’s purported imposition of the AFD on withdrawing employers is legally enforceable. However, we are aware that one large employer that withdrew from PIUMPF has recognized a liability for payment of an AFD amount and that other withdrawing employers have paid some amounts in respect to the AFD. There have been lawsuits in federal courts challenging PIUMPF’s AFD. These lawsuits have not resolved the issue.

If the AFD were held to be legally enforceable, and if we were to elect to withdraw in some future year, the amount of our AFD liability at the time of our withdrawal would be material and subject to a variety of factors including without limitation the nature and timing of a withdrawal, the solvency or insolvency of PIUMPF at the time of the withdrawal, the level of contributions to the plan made by other contributing employers before our withdrawal, whether any employers that had withdrawn in the intervening years had made AFD payments, and the effect of funding provided under ARPA. We are evaluating how PIUMPF’s AFD may be impacted by its use of ARPA funds, although we expect that all other things being equal, the use of ARPA funds will reduce PIUMPF’s AFD over an extended time-period.

We believe that the AFD, if held to be lawful, would be assessed only if an employer voluntarily withdraws from PIUMPF and that plan insolvency or any other circumstance that does not involve a voluntary withdrawal by us would not require us to make a payment in respect of the AFD. Therefore, since we currently have no plans to withdraw from PIUMPF, we have not recognized any liability associated with a withdrawal from PIUMPF in our consolidated financial statements.

If we were to decide to withdraw voluntarily from PIUMPF in the future, and if the AFD were held to be enforceable against us, the resulting liabilities would have a material adverse effect on our results of operations, financial position, liquidity and cash flows. Similarly, if, in the absence of a voluntary withdrawal by us, our understandings as stated above are incorrect regarding the unenforceability of the AFD or the inapplicability of the AFD to us in the event of plan insolvency or other circumstances not involving a voluntary withdrawal by us, the resulting liabilities would have a material adverse effect on our results of operations, financial position, liquidity and cash flows.

Adverse changes to, or requirements under, pension laws and regulations or adverse changes, requirements or claims pursuant to PIUMPF’s rehabilitation plan, such as the AFD, could increase the likelihood and amount of our liabilities. Were we to withdraw from PIUMPF, these liabilities would be in addition to the pension contributions we would have to make to any new pension plan adopted or contributed to by us to replace PIUMPF. All of this could materially reduce the cash we would have available for business and other needs.

Our company-sponsored salary pension plan is currently underfunded, and we may be required to make cash payments to the plan, reducing cash available for our business.

We have a company-sponsored pension plan covering a portion of our salaried and hourly employees. The volatility in the value of equity and fixed income investments held by this plan, coupled with a low interest rate environment resulting in higher liability valuations, has caused the company-sponsored salary plan to be underfunded as the projected benefit obligation has exceeded the aggregate fair value of plan assets by varying year-end amounts since 2008. At December 31, 2021, our company-sponsored salary pension plan was underfunded in the aggregate by $7.4 million. As a result of underfunding, we may be required to make contributions to our company-sponsored salary plan in future years, which would reduce the cash available for business and other needs. In 2021, we made no contributions to the company-sponsored pension plan, and we are not required to make contributions in 2022.

Our pension and health care costs are subject to numerous factors that could cause these costs to change.

In addition to our pension plans, we provide health care benefits to certain of our current and former salaried and hourly employees. Our health care costs vary with changes in health care costs generally, which have significantly exceeded general economic inflation rates for many years. Our pension costs are dependent upon numerous factors resulting from actual plan experience and assumptions about future investment returns. Pension plan assets are primarily made up of equity and fixed income investments. Fluctuations in actual equity market returns as well as changes in general interest rates may result in increased pension costs in future periods. Likewise, changes in assumptions regarding current discount rates, expected rates of return on plan assets and mortality rates could also increase pension costs. Significant changes in any of these factors may adversely impact our cash flows, financial condition and results of operations.

RISKS RELATED TO OUR INDEBTEDNESS

We have a substantial amount of indebtedness, which could have a material adverse effect on our financial condition and our ability to obtain financing in the future and to react to changes in our business.

14

We have a substantial amount of debt, which requires significant principal and interest payments. As of December 31, 2021, we had approximately $644 million face value of debt outstanding, collectively which is related to our Term Loan Credit Agreement (as defined below), $300 million 2014 Notes, $275 million 2020 Notes, ABL Credit Agreement (as defined below) and finance leases. After giving effect to borrowing base limitations and issuance of letters of credit, we had availability of approximately $244 million under the ABL Credit Agreement as of December 31, 2021.

Our significant amount of debt could have important consequences. For example, it could:

•make it more difficult for us to satisfy our obligations under our notes and Credit Agreements (as defined below);

•increase our vulnerability to adverse economic and general industry conditions, including interest rate fluctuations, because a portion of our borrowings, including those under the Credit Agreements, are and will continue to be at variable rates of interest;

•require us to dedicate a substantial portion of our cash flow from operations to payments on our debt, which would reduce the availability of our cash flow from operations to fund working capital, capital expenditures or other general corporate purposes;

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

•place us at a disadvantage compared to competitors that may have proportionately less debt;

•limit our ability to obtain additional debt or equity financing due to applicable financial and restrictive covenants in our debt agreements; and

•increase our cost of borrowing.

Despite our current indebtedness levels, we may still incur significant additional indebtedness. Incurring more indebtedness could increase the risks associated with our substantial indebtedness.

We may be able to incur substantial additional indebtedness, including additional secured indebtedness, in the future. The terms of the Credit Agreements restrict but do not prohibit us from doing so. After giving effect to borrowing base limitations and issuance of letters of credit, we had availability of approximately $244 million under the ABL Credit Agreement as of December 31, 2021. In addition, the Term Loan Credit Agreement allows us to issue additional secured term loans and/or notes under certain circumstances, which would be guaranteed by our subsidiary guarantors. In addition, the indentures governing our notes do not prevent us from incurring certain other liabilities that do not constitute secured indebtedness. If new debt or other liabilities are added to our current debt levels, the related risks that we and our subsidiaries now face could intensify.

We are exposed to risks related to our arrangements with respect to supply chain financing and banking arrangements.

We enter into supply chain financing arrangements with financial institutions to sell certain of our trade receivables without recourse. In addition, we maintain bank accounts with several domestic financial institutions, any of which may prove not to be financially viable. If we were to stop entering into these supply chain financing arrangements, our operating results, financial condition and cash flows could be adversely impacted by delays or failures in collecting trade receivables. However, by entering into these arrangements, and by engaging these financial institutions for banking services, we are exposed to additional risks. If any of these financial institutions experiences financial difficulties or is otherwise unable to honor the terms of our supply chain financing arrangements, we may experience material financial losses due to the failure of such arrangements or a lack of access to our funds, any of which could have an adverse impact upon our operating results, financial condition and cash flows.

If we default under the Credit Agreements, or other indebtedness, we may not be able to service our debt obligations.

In the event of a default under the Credit Agreements or other indebtedness, lenders could elect to declare all amounts borrowed, together with accrued and unpaid interest and other fees, to be due and payable. If such acceleration occurs, thereby permitting an acceleration of amounts outstanding under our debt obligations, we may not be able to repay the amounts due. Events of default are separately defined in each credit agreement or indenture, but include events such as failure to make payments when due, breach of covenants, default under certain other indebtedness, failure to satisfy judgments in excess of a threshold amount, certain insolvency events and the occurrence of a change of control (as defined in the Credit Agreements). The occurrence of an event of default could have serious consequences to our financial condition and results of operations, and could cause us to become bankrupt or insolvent.

15

To service our substantial indebtedness, we must generate significant cash flows. Our ability to generate cash depends on many factors beyond our control, and we may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

As of December 31, 2021, we had approximately $644 million of outstanding indebtedness, and we could incur substantial additional indebtedness in the future. Our ability to make scheduled payments on or to refinance our indebtedness, including our outstanding notes, and to fund planned capital expenditures, will depend on our ability to generate cash from our operations. This, to a significant extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under our credit agreements in an amount sufficient to enable us to pay our indebtedness, including our outstanding notes, or to fund our other liquidity needs. We cannot assure you that we will be able to refinance any of our indebtedness, including our Credit Agreements and our outstanding notes, on commercially reasonable terms or at all.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance our indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. If our operating results and available cash are insufficient to meet our debt service obligations, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. We may not be able to consummate those dispositions or to obtain the proceeds that we could realize from them, and these proceeds may not be adequate to meet any debt service obligations then due. Additionally, our debt agreements limit the use of the proceeds from any disposition; as a result, we may not be allowed, under these documents, to use proceeds from such dispositions to satisfy all current debt service obligations.

Our Credit Agreements, contain various covenants that limit our discretion in the operation of our business.

Our Credit Agreements, contain various provisions that limit our discretion in the operation of our business by restricting our ability to:

•undergo a change in control;

•sell assets;

•pay dividends and make other distributions;

•make investments and other restricted payments;

•redeem or repurchase our capital stock;

•incur additional debt and issue preferred stock;

•guarantee indebtedness;

•create liens;

•consolidate, merge or sell substantially all of our assets;

•enter into certain transactions with our affiliates;

•engage in new lines of business; and

•enter into sale and lease-back transactions.

These restrictions on our ability to operate our business at our discretion could seriously harm our business by, among other things, limiting our ability to take advantage of financing, merger and acquisition and other corporate opportunities, or to borrow in order to fund further capital expenditures.

When (and for as long as) availability, as calculated, under the ABL Credit Agreement is less than a specified amount for a certain period of time, funds deposited into deposit accounts used for collections will be transferred on a daily basis into a blocked account with the administrative agent and applied to prepay loans under the ABL Credit Agreement.

As a result of these covenants and restrictions, we may be limited in how we conduct our business and we may be unable to raise additional debt or equity financing to compete effectively or to take advantage of new business opportunities. The terms of any future indebtedness we may incur could include more restrictive covenants. We cannot assure you that we will be able to maintain compliance with these covenants in the future and, if we fail to do so, that we will be able to obtain waivers from the lenders and/or amend the covenants.

There are various limitations on our ability to incur the full $250 million of commitments under the ABL Credit Agreement and borrowings under our ABL Credit Agreement are limited by a specified borrowing base consisting of a percentage of eligible accounts receivable and inventory, less customary reserves. In addition, under the ABL Credit Agreement, a monthly fixed charge maintenance covenant would become applicable during an event of default or if

16

availability, as calculated under the ABL Credit Agreement, is at any time less than 10.0% of the total $250 million of current revolving loan commitments, or $25 million currently. As of December 31, 2021, availability under the ABL Credit Agreement was approximately $244 million. However, it is possible that availability, as calculated under the ABL Credit Agreement, could fall below the 10% threshold in a future period. If the covenant trigger were to occur, we would be required to satisfy and maintain on the last day of each quarter a fixed charge coverage ratio of at least 1.1x for the preceding four quarter period for which financial statements had been delivered. As of December 31, 2021, our fixed charge coverage ratio was approximately 3.56x. If and when the fixed charge coverage ratio were to be tested, our ability to meet the minimum fixed charge coverage ratio could be affected by events beyond our control, and we cannot assure you that we would meet this ratio at such time. A breach of any of these covenants could result in a default under the ABL Credit Agreement. Events beyond our control could affect our ability to meet these financial tests, and we cannot assure you that we will meet them.

Our failure to comply with the covenants contained in our Credit Agreements or the indentures governing our outstanding notes, including as a result of events beyond our control, could result in an event of default that could cause repayment of the debt to be accelerated.

If we are not able to comply with the covenants and other requirements contained in the indentures governing our outstanding notes, our Credit Agreements or our other debt instruments, an event of default under the relevant debt instrument could occur. If an event of default does occur, it could trigger a default under our other debt instruments, prohibit us from accessing additional borrowings, and permit the holders of the defaulted debt to declare amounts outstanding with respect to that debt to be immediately due and payable. Our assets and cash flow may not be sufficient to fully repay borrowings under our outstanding debt instruments. In addition, we may not be able to refinance or restructure the payments on the applicable debt. Even if we were able to secure additional financing, it may not be available on favorable terms.

Credit rating downgrades could increase our borrowing costs or otherwise adversely affect us.

Some of our outstanding indebtedness has received credit ratings from rating agencies. Our credit ratings could change based on, among other things, our results of operations and financial condition. Credit ratings are subject to ongoing evaluation by credit rating agencies and may be lowered, suspended or withdrawn entirely by a rating agency or placed on a “watch list” for a possible downgrade or assigned a “negative outlook”. Although our indebtedness does not include any triggers that would increase existing borrowing rates if there were a ratings downgrade, actual or anticipated changes or downgrades, including any announcement that our ratings are under review for a downgrade or have been assigned a negative outlook, could increase our future borrowing costs, which could in turn adversely affect our results of operations, cash flows and financial condition, and the trading price of our common stock. If a downgrade were to occur or a negative outlook were to be assigned, it could impact our ability to access the capital markets to raise debt and/or increase the associated costs. In addition, while our credit ratings are important to us, we may take actions and otherwise operate our business in a manner that adversely affects our credit ratings.

The expected replacement of the LIBOR benchmark interest rate and other interbank offered rates with new benchmark rate indices may have an impact on our financing costs.

As of December 31, 2021, we had $50.0 million of debt outstanding under facilities with interest rates based on LIBOR. Our Credit Agreements include fallback language that seeks to facilitate an agreement with our lenders on a replacement rate for LIBOR in the event of its discontinuance or that would replace LIBOR with a new benchmark replacement rate upon certain triggering events. We cannot predict what the impact of any such replacement rate would be to our interest expense, however, the discontinuation, reform, or replacement of LIBOR or any other benchmark rates may result in fluctuating interest rates that may have a negative impact on our interest expense and our profitability. Potential changes to the underlying floating-rate indices and reference rates may have an adverse impact on our liabilities indexed to LIBOR and could have a negative impact on our profitability and cash flows. Furthermore, we cannot predict or quantify the time, effort and cost required to transition to the use of new benchmark rates, including with respect to negotiating and implementing any necessary changes to existing contractual agreements, and implementing changes to our systems and processes.

GENERAL RISK

United States and global economic conditions could have adverse effects on the demand for our products and financial results.

17

U.S. and global economic conditions and currency exchange rates have a significant impact on our business and financial results. Recessed global economic conditions and a strong U.S. dollar could affect our business in a number of ways, including causing declines in global demand for consumer tissue and paperboard, and increased competition from foreign manufacturers in the U.S. market. Foreign currency changes can also impact pricing associated with our raw materials such as pulp and equipment purchases impacting our cost structure.

We may fail to attract, motivate, train and retain qualified personnel, including key personnel.

Our ability to effectively run our business depends on our ability to attract, motivate, train and retain employees with the skills necessary to understand and adapt to the competitive markets in which we operate. The increasing demand for qualified personnel makes it more difficult for us to attract and retain employees with requisite skill sets, particularly employees with specialized technical and trade experience, and can increase our operating and overhead costs. Changing demographics and labor work force trends also may result in a loss of knowledge and skills as experienced workers retire. If we fail to attract, motivate, train and retain qualified personnel, or if we experience excessive turnover, we may experience declining sales, manufacturing delays or other inefficiencies, increased recruiting, training and relocation costs and other difficulties, which may negatively impact our results of operations, cash flows and financial condition.

In addition, we rely on key executive and management personnel to manage our business efficiently and effectively. The loss of any of our key personnel could adversely affect our results of operations, cash flows and financial condition. Effective succession planning is also important to our long-term success. Our failure to identify candidates with the leadership skills to manage our organization, and our failure to ensure effective transfers of knowledge and smooth transitions involving key executives, could hinder our strategic planning and execution.

Certain provisions of our certificate of incorporation and bylaws and Delaware law may make it difficult for stockholders to change the composition of our Board of Directors and may discourage hostile takeover attempts that some of our stockholders may consider to be beneficial.

Certain provisions of our certificate of incorporation and bylaws and Delaware law may have the effect of delaying or preventing changes in control if our Board of Directors determines that such changes in control are not in the best interests of the company and our stockholders. The provisions in our certificate of incorporation and bylaws include, among other things, the following:

•a classified Board of Directors with three-year staggered terms;

•the ability of our Board of Directors to issue shares of preferred stock and to determine the price and other terms, including preferences and voting rights, of those shares without stockholder approval;

•stockholder action can only be taken at a special or regular meeting and not by written consent;

•advance notice procedures for nominating candidates to our Board of Directors or presenting matters at stockholder meetings;

•removal of directors only for cause;

•allowing only our Board of Directors to fill vacancies on our Board of Directors; and

•supermajority voting requirements to amend our bylaws and certain provisions of our certificate of incorporation.

While these provisions have the effect of encouraging persons seeking to acquire control of the company to negotiate with our Board of Directors, they could enable the Board of Directors to hinder or frustrate a transaction that some, or a majority, of the stockholders might believe to be in their best interests and, in that case, may prevent or discourage attempts to remove and replace incumbent directors. We are also subject to Delaware laws that could have similar effects. One of these laws prohibits us from engaging in a business combination with a significant stockholder unless specific conditions are met.

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and related notes that appear elsewhere in this report. This discussion contains forward-looking statements reflecting our current expectations that involve risks and uncertainties. Actual results may differ materially from those discussed in these forward-looking statements due to a number of factors, including those set forth in the section entitled “Risk Factors” and elsewhere in this report. A discussion of the earliest year may be found in Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10‑K filed on February 25, 2021.

OVERVIEW

Executive Summary

For the year ended 2021, we reported net sales of $1.8 billion, down from $1.9 billion reported for the year ended 2020. We reported net loss for the year of $28.1 million, or $1.67 per diluted share, compared to net income of $77.1 million or $4.61 per diluted share in 2020. Adjusted EBITDA was $174.6 million compared to $283.2 million reported in 2020. Decreases in Adjusted EBITDA for 2021 as compared to 2020 were primarily driven by reduced demand for retail tissue as consumers and customers destocked their inventories early in 2021 followed by brief periods of demand spikes based upon the impact of COVID-19 through the year. Decreased demand resulted in lower production which in turn drove decreased fixed cost absorption and lower margins. We also experienced negative impacts due to higher pulp, energy and transportation costs. The pulp and paperboard business benefited in 2021 from significant higher sales prices partially offset by major maintenance in our pulp and paperboard operations. See discussion on segment level results regarding sales, operating results and Adjusted EBITDA in “Our Operating Results” below. See Note 16 "Segment Information" of the Notes to Consolidated Financial Statements included in Item 8 of this report for further information.

Drivers

Paperboard Industry Overview

SBS paperboard is a premium paperboard grade that is most frequently used to produce folding cartons, liquid packaging, cups and plates, blister and carded packaging, top sheet and commercial printing items. SBS paperboard is used for such products because it is manufactured using virgin fiber combined with the kraft bleaching process, which results in superior cleanliness, brightness and consistency. SBS paperboard is often manufactured with a clay coating to provide superior surface printing qualities.

In general, the process of making paperboard begins by chemically cooking wood fibers to make pulp. The pulp is bleached to provide a white, bright pulp, which is formed into paperboard. Bleached pulp that is to be used as market pulp is dried and baled on a pulp drying machine, bypassing the paperboard machines. The various grades of paperboard are wound into rolls for converting to final end users. Liquid packaging and cup stock grades are coated, in a separate operation to create a resistant and durable liquid barrier.

Folding Carton Category. Folding carton is the largest portion of the SBS category of the North America paperboard industry. Within the folding carton segment, there are varying qualities of SBS paperboard, as well as competing paperboard substrates that can be substituted for SBS. The high end of the folding carton category requires a premium print surface and includes uses such as packaging for pharmaceuticals, cosmetics and other premium retail goods. SBS paperboard is also used in the packaging of frozen foods, beverages and baked goods.

Liquid Packaging. Liquid packaging paperboard is used in rigid containers including juice, milk and wine sold in supermarket retail channels.

Cup and Plate Category. Cup and plate category is primarily converted into packaging for premium ice cream, hot and cold cups used in quick service channels and commodity focus plates.

Other. Other applications include carded packaging for blister board alternatives (e.g. batteries and lip stick) and bleached bristols which are used to produce premium printing heavyweight paper grades used in commercial application. Bristols can be clay coated on one side or both sides for applications such as brochures, presentation folders and paperback book covers.

The paperboard industry is affected by macro-economic conditions around the world and has historically experienced cyclical market conditions. As a result, prices for products and sales volumes have historically been volatile. Product

23

pricing is significantly affected by the relationship between supply and demand for our products. Product supply in the industry is influenced primarily by fluctuations in available manufacturing production, which tends to increase during periods when prices remain strong. In 2021, economic conditions resulting from the COVID-19 pandemic, including increased raw material prices, transportation costs, and consistently strong demand, contributed to increased prices for paperboard products.

Tissue Industry Overview

The U.S. tissue market can be divided into two market segments: the at-home or consumer retail purchase segment, which represented over 70% of 2021 U.S. tissue market sales, and away-from-home segment, representing the remaining U.S. tissue market sales and includes tissue for locations such as restaurants, hotels and office buildings (according to Fastmarkets RISI(RISI) U.S. Tissue Monthly Data, November 2021).

The U.S. at-home tissue segment consists of bath, paper towels, facial and napkin products categories. Each category is further distinguished according to quality segments: ultra, premium, value and economy. As a result of manufacturing process improvements and consumer preferences, the majority of at-home tissue sold in the United States is ultra and premium quality. At-home tissue producers are comprised of companies that manufacture branded tissue products, private label tissue products, or both. Branded tissue suppliers manufacture, market and sell tissue products under their own nationally branded labels. Private label tissue producers manufacture tissue products for retailers to sell as their store brand. We estimate that private brands comprise approximately one third of the total tissue market.

In the U.S., at-home tissue is primarily sold through grocery stores, mass merchants, warehouse clubs, drug stores and discount dollar stores. Tissue has experienced steady demand growth largely due to population growth in the United States. In addition to economic and demographic drivers, tissue demand is affected by product innovations and shifts in distribution channels.

The U.S. tissue industry has experienced an increase in ultra and premium tissue products as industry participants have added or improved through-air-dried, or TAD, or equivalent production capacity as well as added conventional tissue capacity. Demand for consumer tissue products during 2021 was volatile given the early inventory destocking followed by brief demand spikes as COVID-19 continued to impact the U.S. As consumers return to pre-COVID-19 away from home activities, we expect this demand for tissue to normalize and approach pre-COVID-19 levels.

Critical Accounting Policies and Significant Estimates

A discussion of our significant accounting policies and significant accounting estimates and judgments is presented in Note 1 of the Notes to Consolidated Financial Statements in Item 8 of this report. Throughout the preparation of the financial statements, we employ significant judgments in the application of accounting principles and methods. We believe that the accounting estimates discussed below represent the accounting estimates requiring the exercise of judgment where a different set of judgments could result in the greatest changes to reported results. We reviewed the development, selection and disclosure of our critical accounting estimates with the Audit Committee of our Board of Directors. For 2021, these significant accounting estimates and judgments include:

Retirement Plans and Postretirement Benefits

We have a number of defined benefit pension plans in the United States covering many of our employees. Benefit accruals under most of our defined benefit pension plan in the United States were frozen prior to January 2014.

We account for the consequences of our sponsorship of these plans using assumptions to calculate the related assets, liabilities and expenses recorded in our financial statements. Net actuarial gains and losses occur when actual experience differs from any of the assumptions used to value defined benefit plans or when assumptions change as they may each year. The primary factors contributing to actuarial gains and losses are changes in the discount rate used to value obligations as of the measurement date and the differences between expected and actual returns on pension plan assets. This accounting method results in the potential for volatile and difficult to forecast gains and losses.

We record amounts relating to these defined benefit plans based on various actuarial assumptions, including discount rates, assumed rates of return, compensation increases and life expectancy. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current economic conditions and trends. We believe that the assumptions utilized in recording our obligations under our plans are reasonable based on our experience and on advice from our independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect our financial condition or results of operations.

24

The following table illustrates the estimated impact on hypothetical pension obligations and expenses that would have resulted from a 25 basis point reduction in two key assumptions for the year ended December 31, 2021 (in millions):

(In millions)	Statement of Operations		Balance Sheets
Discount rate	$	0.5	$	8.5
Expected long term rate of return	$	0.7	$	—

It is not possible to forecast or predict whether there will be actuarial gains and losses in future periods, and if required, the magnitude of any such adjustment. These gains and losses are driven by differences in actual experience or changes in the assumptions that are beyond our control, such as changes in interest rates and the actual return on pension plan assets.

25

Non-GAAP Financial Measures

In evaluating our business, we utilize several non-GAAP financial measures. A non-GAAP financial measure is generally defined by the SEC as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so excluded or included under applicable GAAP guidance. In this report on Form 10-K, we disclose overall and segment earnings (loss) from operations before interest expense, net, non-operating pension and other post employment benefit costs, income tax (benefit), depreciation and amortization, other operating charges, net, and debt retirement costs as Adjusted EBITDA which is a non-GAAP financial measure. Adjusted EBITDA is not a substitute for the GAAP measure of net income or for any other GAAP measures of operating performance.

We have included Adjusted EBITDA on a consolidated and business segment basis in this report because we use it as important supplemental measures of our performance and believe that it is frequently used by securities analysts, investors and other interested persons in the evaluation of companies in our industry, some of which present Adjusted EBITDA when reporting their results. We use Adjusted EBITDA to evaluate our performance as compared to other companies in our industry that have different financing and capital structures and/or tax rates. It should be noted that companies calculate Adjusted EBITDA differently and, therefore, our Adjusted EBITDA measures may not be comparable to Adjusted EBITDA reported by other companies. Our Adjusted EBITDA measures have material limitations as performance measures because they exclude interest expense, income tax (benefit) expense and depreciation and amortization which are necessary to operate our business or which we otherwise incur or experience in connection with the operation of our business. In addition, we exclude other income and expense items which are outside of our core operations.

OUR OPERATING RESULTS

Pulp and Paperboard Segment

Our Pulp and Paperboard segment markets and produces bleached paperboard to quality-conscious printers and packaging converters, and offers services that include custom sheeting, slitting and cutting.

Segment sales, operating income and Adjusted EBITDA for the Pulp and Paperboard segment were as follows:

	For The Years Ended December 31,									Increase (decrease)
(In millions, except per unit and paperboard shipments)	2021			2020			2019			2021-2020		2020-2019
Sales:

Paperboard shipments (short tons)	822,206			821,138			827,459			0.1	%	(0.8)	%
Paperboard sales price (short tons)	$	1,088		$	1,008		$	1,023		8.0	%	(1.5)	%

Sales volumes in our Pulp and Paperboard segment for the year ended December 31, 2021 compared to the year ended December 31, 2020 were flat. Sales prices for the year ended December 31, 2021 compared to the prior year increased significantly due to the impacts of announced price increases across the industry and changes in product mix. These price increases were driven by strong demand and the tightening of the supply of paperboard products. Offsetting the higher prices, the Pulp and Paperboard segment completed its planned major maintenance in 2021 which resulted in higher operating costs relative to the prior year.

Overall, operating income and Adjusted EBITDA for the year ended December 31, 2021 compared to the prior year was essentially flat with higher sales prices in 2021 offset by inflation specifically related to chemicals, freight and energy and our major maintenance outages at both of our facilities which did not occur in in the prior year.

28

Consumer Products Segment

Our Consumer Products segment sells and manufactures a complete line of at-home tissue products and previously sold minor amounts of AFH products prior to the closure of our Neenah, Wisconsin facility in July 2021. Our integrated manufacturing and converting operations and geographic footprint enable us to deliver a broad range of cost-competitive products with brand equivalent quality to our customers.

Segment sales, operating income and Adjusted EBITDA for the Consumer Products segment were as follows:

1 Excludes contract manufacturing cases of 157, 314 and 807 for the years ended December 31, 2021, 2020 and 2019.

Sales volumes decreased in our Consumer Products segment for the year ended December 31, 2021 compared to the prior year as consumer demand slowed due to the lessening impact of COVID-19. Sales prices changed in our Consumer Products segment for the year ended December 31, 2021 compared to the prior year due primarily to changes in product mix. We saw an increase in our non-retail business related to increases in parent rolls sales offset by reductions in our away from home business due to the announced closure of our Neenah, Wisconsin facility during 2021. Sales prices in this category decreased in the period due to a higher percentage of parent rolls sales which are generally sold at a lower price.

Overall, decrease in operating income and Adjusted EBITDA for the year ended December 31, 2021 compared to the prior year was driven by higher input costs, primarily pulp, reduced operations to balance supply and demand and lower sales volumes due to lessening impacts of COVID-19.

Corporate expenses

Corporate expenses were $60.1 million in 2021 as compared to $63.0 million in 2020. The reduction between years is

primarily related to the lower incentive compensation due to lower financial results. Corporate expenses primarily

consist of corporate overhead such as wages and benefits, professional fees, insurance and other expenses for corporate

29

functions including certain executive officers, public company costs, information technology, financial services,

environmental and safety, legal, supply management, human resources and other corporate functions not directly associated with the business operations.

Other operating charges

See Note 9 "Other Operating Charges, net" of the Notes to the Consolidated Financial Statements included in Item 8 of this report for additional information.

Interest expense, net

Interest expense for the year ended December 31, 2021 compared to December 31, 2020 was $10.1 million lower due to lower debt outstanding. See Note 10 "Non-operating income (expense)" of the Notes to the Consolidated Financial Statements included in Item 8 of this report for additional information.

Potential impairments

We review from time to time possible dispositions or reorganization of various assets in light of current and anticipated

economic and industry conditions, our strategic plan and other relevant factors. Because a determination to

dispose or reorganize particular assets may require management to make assumptions regarding the transaction structure of the disposition or reorganization and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.

LIQUIDITY AND CAPITAL RESOURCES

Overview

Our principal sources of liquidity are existing cash, cash generated by our operations and our ability to borrow under such credit facilities as we may have in effect from time to time. At times, we may also issue equity, debt or hybrid securities or engage in other capital market transactions. Due to the competitive and cyclical nature of the markets in which we operate, there is uncertainty regarding the amount of cash flows we will generate during the next twelve months. However, we believe that our cash flows from operations, our cash on hand and our borrowing capacity under our credit agreements will be adequate to fund debt service requirements and provide cash to support our ongoing operations, capital expenditures and working capital needs for the next twelve months.

Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness and making capital expenditures. We may also from time to time prepay or repurchase outstanding indebtedness or shares or acquire assets or businesses that are complementary to our operations. Any such repurchases may be commenced, suspended, discontinued or resumed, and the method or methods of effecting any such repurchases may be changed at any time or from time to time without prior notice.

Operating Activities

During 2021, we generated $96.4 million of cash from operations, as compared to $247.0 million in 2020. This decrease was driven by decreases in our net income and changes in working capital due to decreased demand in our consumer products division which resulted in higher inventories. Accounts receivable and accounts payable agings have remained relatively consistent with balances as of December 31, 2020.

Investing Activities

During 2021 we used $25.1 million in cash for investing activities attributable to $38.4 million of capital expenditures partially offset by $13.3 million of proceeds from divested assets, as compared to $39.6 million for capital expenditures during 2020. Capital expenditures were primarily related to maintenance projects. Included in accounts payable and accrued liabilities was $11.0 million related to capital expenditures that had not yet been paid at December 31, 2021.

In 2022, we expect cash paid for capital expenditures to be approximately $60 million to $70 million.

Financing Activities

Net cash flows used in financing activities were $82.0 million for 2021 as compared to $192.9 million for 2020. The change was driven by lower debt repayments for the year ended December 31, 2021 as compared to the prior year.

30

Commitments

As of December 31, 2021, we have purchase commitments of $108.7 million million related to contracts for the purchase of chemicals, pulp and contracts with natural gas and electricity providers that are legally binding on us and specify fixed or minimum quantities. Additionally, we have $16.4 million in purchase commitments associated with capital expenditures.

Credit Agreements

We must make mandatory prepayments of principal under the Term Loan Credit Agreement upon the occurrence of certain specified events, including based upon a percentage of annual Excess Cash Flow we generate which can fluctuate depending on our Senior Secured Leverage Ratio (as those terms are defined in the Term Loan Credit Agreement). For instance, if our Senior Secured Leverage Ratio on the last day of a fiscal year is below 1.50x, we are not subject to an Excess Cash Flow mandatory prepayment. There is uncertainty in the amount of Excess Cash Flow that we may generate during the current fiscal year, therefore, we are unable to estimate the mandatory prepayment under the Term Loan Credit Agreement that could be required at the time such payment is due in 2022. During the year ended December 31, 2021, we prepaid $79 million of principal under the Term Loan Credit Agreement. Amounts repaid or prepaid cannot be reborrowed. However, we may add one or more incremental term loan facilities to the Term Loan Credit Agreement, subject to obtaining commitments from any participating lenders and certain other conditions, so long as our first lien secured leverage ratio does not exceed 2.00x to 1.00x. At December 31, 2021, our first lien secured leverage ratio was 0.24x.

The ABL Credit Agreement includes a $250 million revolving loan commitment, subject to borrowing base limitations. Borrowings under the ABL Credit Agreement are subject to mandatory prepayment in certain circumstances. We may also increase commitments under the ABL Credit Agreement in an aggregate principal amount of up to $100 million, subject to obtaining commitments from any participating lenders and certain other conditions.

Both credit agreements contain certain customary representations, warranties, and affirmative and negative covenants. The ABL Credit Agreement also contains a financial covenant, which requires us to maintain a consolidated fixed charge coverage ratio of not less than 1.10x to 1.00x, provided that the financial covenant under the ABL Credit Agreement is only applicable when availability falls below $25 million.

At December 31, 2021, we were in compliance with the Credit Agreements, and based on our current financial projections, we expect to remain in compliance. However, if our financial position, results of operations or market conditions deteriorate, we may not be able to remain in compliance. There can be no assurance that we will be able to remain in compliance with our Credit Agreements. If we are unable to do so, it would be necessary to seek an amendment from our lenders, which, if obtained, could require payment of additional fees, increased interest rates or other conditions or restrictions. See Note 8, "Debt" to the Notes to Consolidated Financial Statements included in this report for additional discussion of our Credit Agreements.

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Our exposure to market risk on financial instruments includes interest rate risk on our Term Loan and ABL Credit Agreements. As of December 31, 2021, there were $50.0 million in borrowings outstanding under our Term Loan Agreement and no outstanding borrowings under our ABL Credit Agreement. The interest rates applied to our Credit Agreements are adjusted often and therefore react quickly to any movement in the general trend of market interest rates. A one percentage point increase or decrease in interest rates, based on assumed outstanding borrowings of $50.0 million, would have a $0.5 million annual effect on interest expense.

Foreign Currency Risk

We have minimal foreign currency exchange risk. Nearly all of our international sales are denominated in U.S. dollars.

ITEM 8. Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors

Clearwater Paper Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Clearwater Paper Corporation and subsidiaries (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes (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, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2021, 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, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 15, 2022 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates 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 a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Measurement of the pension benefit obligation

As discussed in Notes 1 and 11 to the consolidated financial statements, the Company’s pension benefit obligation was $310.1 million as of December 31, 2021. The measurement of the pension benefit obligation is based on actuarial assumptions that require judgment, which includes the discount rate applied to the pension benefit obligation.

33

We identified the evaluation of the discount rate used in the measurement of the pension benefit obligation as a critical audit matter. Specialized skills and knowledge were required to evaluate the discount rate used to determine the pension benefit obligation. In addition, there was subjectivity and judgment in applying and evaluating results of the procedures due to the sensitivity of the pension benefit obligation to changes in the discount rate.

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 controls over the Company’s pension benefit process. This included controls related to the determination of the discount rate assumption. We considered the change in the discount rate from that used in the prior year, including consideration of the changes in the discount rate in light of published reports of actuarial experts. We involved an actuarial professional with specialized skills and knowledge, who assisted in evaluating the discount rate as determined using the hypothetical bond portfolio model through analyzing the bond selection criteria, the bond ratings, and the cash flow matching of the model.

We have served as the Company’s auditor since 2007.

NOTE 1 Summary of Significant Accounting Policies

NATURE OF OPERATIONS AND BASIS OF PRESENTATION

We are a premier supplier of bleached paperboard and consumer and parent roll tissue. We supply bleached paperboard to quality-conscious printers and packaging converters, and offer services that include custom sheeting, slitting and cutting. We supply private label tissue to major retailers and wholesale distributors, including grocery, club, mass merchants and discount stores.

Unless the context otherwise requires or unless otherwise indicated, references in this report to “Clearwater Paper Corporation,” “we,” “our,” “the Company” and “us” refer to Clearwater Paper Corporation and its subsidiaries.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates.

PRINCIPLES OF CONSOLIDATION

These consolidated financial statements include the financial condition and results of operations of Clearwater Paper Corporation and its wholly-owned subsidiaries. All intercompany transactions and balances between operations within the Company have been eliminated.

CASH, CASH EQUIVALENTS AND RESTRICTED CASH

We consider all highly liquid instruments with maturities of three months or less to be cash equivalents. Cash that is held by a third party and has restrictions on its availability to us is classified as restricted cash. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported on the Consolidated Balance Sheets to the sum of those same amounts shown in our Consolidated Statements of Cash Flows.

INVENTORIES

Our inventories are stated at the lower of net realizable value or current cost using the average cost method.

Paperboard and tissue products	148.0		137.0
Materials and supplies	100.1		97.7
	$	277.7	$	263.3

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost, including assets acquired under finance lease obligations, and any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Estimated useful lives generally range from 10 to 40 years for land improvements, 10 to 40 years for buildings and improvements and 2 to 25 years for machinery and equipment (includes office and other equipment).

	December 31,
(In millions)	2021		2020
Land and land improvements	$	109.1	$	111.5
Buildings and improvements	452.5		480.1
Machinery and equipment	2,377.5		2,459.2
Construction in progress	22.4		21.8
	2,961.5		3,072.6
Less accumulated depreciation and amortization	(1,879.7)		(1,881.1)
Property, plant and equipment, net	$	1,081.8	$	1,191.5

At December 31, 2021 and 2020, included within property, plant and equipment, net were finance leases of $27.7 million and $26.7 million and associated accumulated depreciation amounts of $15.2 million and $12.7 million.

Depreciation expense totaled $102.0 million, $107.8 million and $108.4 million for the years ended December 31, 2021, 2020 and 2019.

Capitalized interest is charged to and amortized over the lives of the related assets. For the years ended December 31, 2021, 2020 and 2019 capitalized interest expense was $0.3 million, zero, and $5.9 million.

PLANNED MAINTENANCE

We recognize the cost of repair and maintenance activities in the period in which the activity is performed or goods are received under the direct expense method. We perform planned maintenance activities at our facilities periodically and associated expenses are included in cost of sales.

LEASES

Operating lease right-of-use (ROU) assets and liabilities are recognized at the commencement date of a lease based on the present value of lease payments over the lease term. Our leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the ROU assets and liabilities. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles, and leases within supply agreements primarily relate to usage, repairs and maintenance. As the implicit rate is not readily determinable for most of our leases, we apply a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use our unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate. Leases having a lease term of twelve months or less are not recorded on the balance sheet and the related lease expense is

42

recognized on a straight-line basis over the term of the lease. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases.

See Note 4, "Leases" for further information.

RETIREMENT PLANS AND POSTRETIREMENT BENEFITS

We are required to use actuarial methods and assumptions in the valuation of defined benefit obligations and other postretirement obligations and the determination of expense. Differences between actual and expected results or changes in the values of the obligations and plan assets are not recognized in earnings as they occur but, rather, systematically and gradually over subsequent periods.

See Note 11, "Retirement Plans and Postretirement Benefits" for further information.

INCOME TAXES

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The determination of our provision for income taxes requires significant judgment, the use of estimates, and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in our consolidated financial statements only after determining a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from tax authorities. When facts and circumstances change, we reassess these probabilities and record any changes in the consolidated financial statements as appropriate.

See Note 6, "Income Taxes" for further information.

REVENUE RECOGNITION

We enter into contracts that can include various combinations of tissue and paperboard products, which are generally distinct and accounted for as separate performance obligations.

Generally, revenue is recognized at a point in time upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Transfer of control typically occurs when the title and risk of loss passes to the customer. Shipping terms generally indicate when title and the risk of loss have passed, usually this is upon receipt at our customer's destination. We have elected to treat shipping and handling costs as a fulfillment cost. We typically expense incremental direct costs of obtaining a contract (sales commissions) when incurred because the amortization period is generally 12 months or less. We maintain consignment inventory at a limited number of customer locations. For consigned inventory, we recognize revenue upon transfer of control, which is often in advance of invoicing the customer. These amounts are classified as unbilled receivables in the above detail of accounts receivable.

We provide for trade promotions, customer cash discounts and other deductions, which are considered variable consideration and recorded as a reduction of net sales. Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. Revenue, net of returns and credits, is only recognized to the extent that it is probable that a significant reversal of any incremental revenue will not occur. Judgment associated with forecasted volumes is required to determine the most probable amount of variable consideration to apply as a reduction to net sales. As of December 31, 2021 and 2020, we had $9.2 million and $10.5 million accrued as customer rebates. Revenue is recognized net of any taxes collected from customers.

See Note 16, "Segment Information" for further information, including the disaggregation of revenue by segment, primary geographical market, and major product type.

OTHER OPERATING CHARGES, NET

We classify significant amounts unrelated to ongoing core operating activities as “Other operating charges, net” in the Consolidated Statements of Operations. Such items include, but are not limited to, amounts related to facility closures and related gain (loss) on sale and impairment, restructuring charges (including severance charges), charges to establish and maintain litigation or environmental reserves, gains or losses from settlements with governmental or other organizations and cash settled equity-based compensation to our directors. Due to the nature of these items, amounts in the statement of operations can fluctuate from year to year. The determination of which items are considered significant and unrelated to core operations is based upon management’s judgment.

See Note 9, "Other Operating Charges, net" for a discussion of specific amounts in 2021, 2020 and 2019.

ACCOUNTS RECEIVABLE ARRANGEMENT

During 2019, we entered into an uncommitted supply-chain financing program with a global financial institution under which a specific customer's trade accounts receivable may be acquired, without recourse, by the institution at a discounted rate. Available capacity under this program is dependent on the level of our trade accounts receivable with this customer and the financial institution’s willingness to purchase such receivables. We have no servicing responsibilities under this agreement. This agreement allows us to obtain payment more quickly than under the contractual terms of sale to this customer.

Receivables sold are de-recognized from our Consolidated Balance Sheet. For the years ended December 31, 2021 and 2020, we sold $202.2 million and $256.2 million, of receivables. The proceeds from these sales of receivables are included within operating activities in our Consolidated Statements of Cash Flows. For the years ended December 31, 2021, 2020, and 2019 factoring expense on the sale of receivables was $0.9 million, $1.2 million, and $1.0 million.

ENVIRONMENTAL AND ASSET RETIREMENT OBLIGATIONS

We estimate our environmental and asset retirement obligations based on various assumptions and judgments, the specific nature of which varies in light of the particular facts and circumstances surrounding each liability. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of required investigation, remediation and monitoring activities and the probable cost of these activities. We have accrued only for specific costs related to environmental matters that we have determined are probable and for which an amount can be reasonably estimated. For asset retirement obligations, the liability is accreted to its settlement value and, where appropriate, the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we recognize a gain or loss for any difference between the settlement amount and the liability recorded. Our asset retirement obligation is included in "Other long-term obligations" in the Consolidated Balance Sheets. Our asset retirement obligation reflects the estimated present value of our obligations for capping, closure and post closure cost with respect to landfills, asbestos remediation and other ongoing environmental monitoring. The following table represents the activity associated with our asset retirement obligations.

NOTE 2 Recently Adopted and New Accounting Standards

RECENTLY ADOPTED

In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which removes certain exceptions, such as the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year, and simplifies the accounting for income taxes in areas such as franchise tax (or similar tax) that is partially based on income. The new standard is effective for annual and interim periods beginning after December 15, 2020. This ASU was adopted as of January 1, 2021 and did not have a material impact on our consolidated financial statements.

NEW ACCOUNTING STANDARDS

In November 2021, the FASB issued ASU 2021-10, Disclosures by Business Entities About Government Assistance (Topic 832), which requires disclosures about certain types of government assistance including the nature of the assistance, related accounting policies, and the effect on an entity's financial statements. The new standard is effective for annual periods beginning after December 15, 2021 with prospective or retrospective adoption permitted. We plan to adopt this ASU prospectively and do not believe it will have a material impact on our consolidated financial statements.

NOTE 3 Fair Value Measurements

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. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We are required to classify these financial assets and liabilities into two groups: recurring-measured on a periodic basis and non-recurring-measured on an as needed basis.

There are three levels of inputs that may be used to measure fair value:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities.

Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; or valuations based on models where the significant inputs are observable or can be corroborated by observable market data.

Level 3: Valuations based on models where significant inputs are not observable. Unobservable inputs are used when little or no market data is available and reflect the Company’s own assumptions about the assumptions market participants would use.

Carrying amounts reported on the balance sheets for cash and cash equivalents, restricted cash, receivables and accounts payable approximate fair value due to the short-term maturity of these instruments. See discussion on fair market values for Long-term Debt included within Note 8, "Debt".

We review the carrying values of goodwill and long-lived assets to be held and used for impairment wherever events or changes in circumstances indicate possible impairment. An impairment loss is recognized when a long-lived asset's carrying value is not recoverable and exceeds estimated fair value. See Note 5, "Goodwill and Intangible Assets" for discussion of fair market values for goodwill.

NOTE 4 Leases

We have operating leases for manufacturing, office, warehouse, equipment and vehicles. Our leases have remaining lease terms from less than one to nine years, and some of our leases include one or more options to renew.

As of December 31, 2020, intangible assets consisted of $12.8 million of customer relationships, $0.7 million of tradenames and trademarks and $0.2 million of other intangibles. Outstanding definite-lived intangible assets are amortized over their useful lives of 10 years.

We annually evaluate goodwill for possible impairment as of November 1 with additional interim evaluation performed when management believes that it is more likely than not that events or circumstances have occurred that would result in the impairment of a reporting unit’s goodwill. We evaluate our intangible assets for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable.

The gross book value and accumulated amortization of definite lived intangible assets at December 31, 2021 was $34.9 million and $24.1 million. The gross book value and accumulated amortization of definite lived intangible assets at December 31, 2020 was $63.8 million and $50.1 million.

NOTE 6 Income Taxes

We are subject to corporate level federal and state income taxes in the United States.

IMPACT OF THE CARES ACT

On March 27, 2020, the "Coronavirus Aid, Relief and Economic Security (CARES) Act" was signed. The CARES Act, among other things, included provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carry back periods, alternative minimum tax credit refunds, modifications to net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvements property. During 2020, we recognized a $7.0 million benefit from the provisions of the Act.

INCOME TAX PROVISION (BENEFIT)

The components of income tax provision (benefit) is comprised of the following:

	For The Years Ended December 31,
(In millions)	2021		2020		2019

1Included in "Other assets, net" on our accompanying December 31, 2021 and 2020 Consolidated Balance Sheets.

We have tax benefits associated with state jurisdictions totaling $9.1 million which expire between 2022 and 2041.

UNCERTAIN TAX POSITIONS

The following table provides a roll forward of our unrecognized tax benefits and associated interest and penalties.

(In millions)	Gross Unrecognized Tax Benefits, Excluding Interest and Penalties		Interest and Penalties		Total Gross Unrecognized Tax Benefits
Balance at December 31, 2019	$	3.7	$	0.4	$	4.1

Balance at December 31, 2021	$	5.6	$	0.3	$	5.9

Unrecognized tax benefits net of related deferred tax assets at December 31, 2021, if recognized, would have favorably impacted our effective tax rate by decreasing our tax provision by $5.5 million. For each of the years ended December 31, 2020 and 2019, if recognized, the balance of unrecognized tax benefits would have favorably impacted our effective tax rate by $6.4 million and $3.5 million. We reflect accrued interest related to tax obligations, as well as penalties, in our provision for income taxes. For each of the years ended December 31, 2021, 2020, and 2019, we accrued interest of less than $0.1 million each year in our income tax provision and no penalties in our income tax provision.

We have operations in many states within the U.S. and are subject, at times, to tax audits in these jurisdictions. With a few exceptions, we are no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for years prior to 2015. We expect that the outcome of any examination will not have a material effect on our consolidated financial statements. Although the timing of resolution of audits is not certain, we evaluate all audit issues in the aggregate, along with the expiration of applicable statutes of limitations, and estimate that it is reasonably possible the total gross unrecognized tax benefits could decrease by approximately $2.6 million within the next 12 months.

Deferred debt costs are amortized over the life of the related debt using a straight line basis which approximates the effective interest method. These costs are a direct deduction from the carrying amount related to the debt liability. If the debt is retired early, the related unamortized deferred debt costs are expensed in the period the debt is retired to debt retirement costs.

We amortized deferred debt costs of $1.8 million, $2.1 million and $2.0 million for the years ended December 31, 2021, 2020 and 2019. Included in these amortized amounts are deferred debt costs associated with our current line of credit, which is recorded within "Other current assets" and "Other assets, net" on our Consolidated Balance Sheets.

During 2020, in connection with the issuance of the 2020 Notes, we redeemed the 2013 Notes in full. This redemption resulted in a loss on early debt retirement of $3.2 million consisting of $1.2 million related to the write off of unamortized debt costs along with the premium on debt redemption of $2.1 million.

TERM LOAN AND ABL CREDIT AGREEMENTS

On July 26, 2019, we entered into credit agreements with several lenders and JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent, which included (a) a $300 million Term Loan Credit Agreement and (b) a $250 million asset based lending (ABL) Credit Agreement (collectively referred to as the Credit Agreements). At closing, the Term Loan Credit Agreement was fully advanced and $58.0 million was drawn under the ABL Credit Agreement, proceeds of which were used to refinance and terminate our: (a) $200 million credit agreement dated October 31, 2016, as amended, with Wells Fargo Bank, National Association (Wells Fargo), as administrative agent, and the lenders party thereto, of which $135.0 million was outstanding and (b) the $200 million credit agreement dated October 31, 2016, as amended, with Northwest Farm Credit Services, PCA, (Farm Credit) as administrative agent, and the lenders party thereto, of which $200.0 million was outstanding (the Prior Credit Agreements); pay fees and expenses in connection with the Credit Agreements; and for working capital purposes.

In conjunction with the termination of the Prior Credit Agreements, of which the $200 million credit agreement with Wells Fargo was treated as a debt modification, debt retirement costs consisted of $1.7 million in breakage fees and $1.0 million in unamortized debt issuance costs. Unamortized debt issuance costs of $1.6 million, related to the debt modification, are being amortized over the remaining term of the ABL Credit Agreement. We incurred additional debt issuance costs of $7.3 million, which were allocated and will be amortized over the respective terms of the Credit Agreements.

The Credit Agreements contain certain customary representations, warranties, and affirmative and negative covenants of us and our subsidiaries that restrict us and our subsidiaries’ ability to take certain actions, including, incurrence of indebtedness, creation of liens, mergers or consolidations, dispositions of assets, repurchase or redemption of capital stock and certain types of indebtedness, making certain investments, entering into certain transactions with affiliates or changing the nature of our business. At December 31, 2021, we were in compliance with the Credit Agreements.

Term Loan Credit Agreement

The Term Loan Credit Agreement matures on July 26, 2026. We are required to repay the aggregate outstanding principal amount in quarterly installments in an aggregate amount for each such date equal to the aggregate principal amount of the initial loan amount (as such amount may be adjusted pursuant to the prepayment provisions of the Term Loan Credit Agreement) multiplied by 0.25%. Through December 31, 2021, we have made voluntary principal prepayments of the Term Loan Credit Agreement of $79.3 million, and accordingly we have fulfilled all scheduled payments through maturity. In connection with the voluntary repayments, we recorded early debt retirement costs related to the expensing of deferred debt costs of $1.0 million and $2.6 million for the periods ended December 31, 2021 and December 31, 2020.

In addition, we must make mandatory prepayments of principal under the Term Loan Credit Agreement upon the occurrence of certain specified events, including certain asset sales (subject to customary reinvestment rights), debt issuances not permitted under the Term Loan Credit Agreement, and based on a percentage, which may vary from 0% to 50% depending on our secured leverage ratio, of annual excess cash flows in excess of certain threshold amounts, less any voluntary prepayments under the Term Loan Credit Agreement. Any remaining outstanding principal balance under the Term Loan Credit Agreement is repayable on the maturity date. Amounts repaid or prepaid by us with respect to the loans under the Term Loan Credit Agreement cannot be reborrowed.

We may add one or more incremental term loan facilities to the Term Loan Credit Agreement, subject to obtaining commitments from any participating lenders and certain other conditions, in an amount not to exceed (1) $100 million, plus (2) the amount of all voluntary prepayments of the Term Loan Credit Agreement (other than prepayments funded with long-term indebtedness), plus (3) an additional amount, so long as after giving effect to the incurrence of such additional amount, our pro forma first lien secured leverage ratio would not exceed 2.00x to 1.00x. At December 31, 2021 our first lien secured ratio was 0.24x. Under the Term Loan Credit Agreement, loans generally may bear interest

52

based on LIBOR or an annual base rate, as applicable, plus, in each case, an applicable margin. When our leverage ratio is (i) less than or equal to 4.25 to 1.00, the margin is 3.00% per annum in the case of LIBOR loans and 2.00% per annum in the case of annual base rate loans and (ii) greater than 4.25 to 1.00, the margin is 3.25% per annum in the case of LIBOR loans and 2.25% per annum in the case of annual base rate loans. At December 31, 2021, our leverage ratio was 3.4x and therefore our applicable margin on LIBOR loans was 3.00%.

ABL Credit Agreement

The ABL Credit Agreement matures on July 26, 2024 and includes a $250.0 million revolving loan commitment, subject to borrowing base limitations based on a percentage of applicable eligible receivables and eligible inventory. Based upon our Consolidated Balance Sheets as of December 31, 2021, our eligible receivables and inventory supported up to $243.6 million availability under the line of which no borrowings were outstanding and $3.6 million was utilized to issue letters of credit. We may, at our option, prepay any borrowings under the ABL Credit Agreement, in whole or in part, at any time and from time to time without premium or penalty (except in certain circumstances). Borrowings under the ABL Credit Agreement are also subject to mandatory prepayment in certain circumstances, including in the event that borrowings exceed applicable borrowing base limits. We may also increase commitments under the ABL Credit Agreement in an aggregate principal amount of up to $100 million, subject to obtaining commitments from any participating lenders and certain other conditions.

Under the ABL Credit Agreement, loans may bear interest based on LIBOR or an annual base rate, as applicable, plus, in each case, an applicable margin that is based on availability, as calculated under the ABL Credit Agreement that may vary from 1.25% per annum to 1.75% per annum in the case of LIBOR loans and 0.25% per annum to 0.75% per annum in the case of annual base rate loans. In addition, a commitment fee based on unused availability is also payable which may vary from 0.25% per annum to 0.375% per annum.

The ABL Credit Agreement also contains a financial covenant, which requires us to maintain a consolidated fixed charge coverage ratio of not less than 1.10x to 1.00x, provided that the financial covenant under the ABL Credit Agreement is only applicable when unused availability falls below $25 million. As of December 31, 2021, our fixed charge coverage ratio was approximately 3.56x. Our ability to utilize our ABL Credit Agreement could be limited in the future by our bond indentures which have limitations on liens.

2014 NOTES

In 2014, we issued $300 million aggregate principal amount of senior notes (2014 Notes), due February 1, 2025, with an interest rate of 5.375%.

The 2014 Notes are guaranteed by all of our direct and indirect domestic subsidiaries, as well as any future direct and indirect domestic subsidiaries that do not constitute an immaterial subsidiary under the indenture governing the 2014 Notes. The 2014 Notes are equal in right of payment with all other existing and future unsecured senior indebtedness and are senior in right of payment to any future subordinated indebtedness. The 2014 Notes are effectively subordinated to all of our existing and future secured indebtedness, including borrowings under our Term Loan and ABL Credit Agreements. The terms of the 2014 Notes limit our ability and the ability of any restricted subsidiaries to incur certain liens, engage in sale and leaseback transactions and consolidate, merge with, or convey, transfer or lease substantially all of our or their assets to another person.

We may, on any one or more occasions, redeem all or a part of the 2014 Notes, upon not less than 30 days nor more than 60 days' notice, at a redemption price equal to 100% of the principal amount of the 2014 Notes redeemed, plus the applicable premium as of, and accrued and unpaid interest, to the date of redemption. In addition, we may be required to make an offer to purchase the 2014 Notes upon the sale of certain assets or upon a change of control.

2020 NOTES

In 2020, we issued $275 million aggregate principal amount of senior notes (2020 Notes) due August 2028 with an interest rate of 4.75%.

The 2020 Notes are unsecured and effectively subordinated to all of the Company’s existing and future secured debt, including borrowings under its existing credit facilities. The 2020 Notes are guaranteed on an unsecured basis by each of the Company’s existing direct and indirect domestic subsidiaries, and will be guaranteed by each of the Company’s future direct and indirect domestic subsidiaries, subject to certain exceptions. If the Company is unable to make payments on the 2020 Notes when they are due, each Guarantor is obligated to make such payments.

53

The Indenture contains covenants that, among other things, limit our ability and the ability of any of our subsidiaries to (i) enter into sale leaseback transactions, (ii) incur liens and (iii) consolidate, merge or sell all or substantially all of our assets. In addition, the Indenture requires, among other things, we provide certain reports to holders of the 2020 Notes. These covenants are subject to a number of exceptions, limitations and qualifications as set forth in the Indenture.

We may redeem all or a portion of the 2020 Notes at specified redemption prices plus accrued and unpaid interest. In addition, we may be required to make an offer to purchase the 2020 Notes upon the sale of certain assets and upon a change in control.

NOTE 11 Retirement Plans and Postretirement Benefits

Certain of our employees are eligible to participate in defined contribution savings and defined benefit postretirement plans. These include 401(k) savings plans, defined benefit pension plans including company-sponsored and multiemployer plans, and other postretirement employee benefit (OPEB) plans.

401(k) Savings Plans

Substantially all of our employees are eligible to participate in 401(k) savings plans, which include a company match component. As of December 31, 2021 our contributions may be up to 7.7% for U.S. salaried and non-union hourly employees, consisting of a match of up to 4.2% of allowable contributions and an automatic employer contribution of 3.5%. Contributions associated with our union employees are based upon negotiated agreements. In 2021, 2020 and 2019, we recorded expense of $16.4 million, $17.3 million, and $15.3 million related to employer contributions to the 401(k) plans.

55

Company-Sponsored Defined Benefit Pension and OPEB Plans

A portion of our salaried and hourly employees are covered by company-sponsored noncontributory defined benefit pension plans. We provide retiree health care and life insurance plans, which cover certain salaried and hourly employees. Retiree health care benefits for Medicare eligible participants over the age of 65 are provided through Health Reimbursement Accounts, or HRA's. Benefits for retirees under the age of 65 are provided under our company-sponsored health care plans, which require retiree contributions and contain other cost-sharing features. The retiree life insurance plans are primarily noncontributory.

We also maintain a Salaried Supplemental Benefit Plan, an unfunded, non-qualified defined benefit plan intended to provide supplemental retirement benefits to certain executives. Benefits in the Salaried Supplemental Benefit Plan are generally provided to restore benefits or company contributions that are reduced under the Company sponsored qualified plans due to the limits of Section 401(a)(17) or 415 of the Code. The plan is composed of a defined benefit portion and a defined contribution portion. The defined benefit portion of the plan was frozen on December 31, 2011 (the date on which all benefit accruals under the Salaried Retirement Plan were frozen) and as of December 31, 2021, we had two active employees under this portion. We paid benefits of $0.4 million associated with the defined benefit portion of the plan in 2021. The defined contribution portion of this liability totaled $1.4 million and $2.4 million at December 31, 2021 and December 31, 2020. The current and long term portions of the liability is included in “Accrued compensation” and “Other long-term obligations” on our Consolidated Balance Sheets. The defined benefit portion is included in the pension benefit plans tables below.

Pension and Other Postretirement Employee Benefit Plans

The following table shows the changes in the benefit obligation, plan assets and funded status for 2021 and 2020 for both the pension benefit plans and the other postretirement employee benefit plans.

	Pension Benefit Plans				Other Postretirement Employee Benefit Plans

The benefit obligation for our pension benefits is the projected benefit obligation based upon credited service as of the measurement date.

56

The December 31, 2021 pension funded status was favorably affected by an increase in the discount rate, partially offset by lower than expected asset returns. The December 31, 2021 OPEB benefit obligation decreased as of December 31, 2021 due to an increase in the discount rate, decrease in claim costs assumptions, and the continued payment of benefits, partially offset by demographic changes.

Information as of December 31 for certain pension plans included above with accumulated benefit obligations in excess of plan assets were as follows:

(In millions)	2021		2020
Projected benefit obligation	$	173.9	$	188.7
Accumulated benefit obligation	173.9		188.7
Fair value of plan assets	166.4		176.2

Net Periodic Cost

Service cost is the actuarial present value of benefits attributed by the plans’ benefit formula to services rendered by employees during the year. Interest cost represents the increase in the projected benefit obligation, which is a discounted amount, due to the passage of time. The expected return on plan assets reflects the computed amount of current-year earnings from the investment of plan assets using an estimated long-term rate of return.

	Pension Benefit Plans						Other Postretirement Employee Benefit Plans
(In millions)	2021		2020		2019		2021		2020		2019
Service cost	$	1.8	$	2.2	$	2.4	$	0.4	$	0.1	$	0.1
Interest cost	8.4		10.4		12.4		2.0		2.3		2.8
Expected return on plan assets	(10.6)		(15.0)		(16.5)		—		—		—
Amortization of actuarial loss (gain)	10.2		9.8		7.3		0.3		—		(0.3)
Net periodic cost (income)	$	9.9	$	7.5	$	5.6	$	2.7	$	2.4	$	2.6

The components of net periodic pension expense other than the Service cost component are included in "Other non-operating expense" in the Consolidated Statements of Operations. During 2021, 2020, and 2019, $2.0 million, $1.9 million and $1.5 million of net periodic pension and OPEB costs were charged to "Cost of sales" and $0.2 million, $0.5 million and $1.0 million were charged to "Selling, general and administrative expenses," in the accompanying Consolidated Statements of Operations.

Assumptions:	Pension Benefit Plans						Other Postretirement Employee Benefit Plans
	2021		2020		2019		2021		2020		2019
Actuarial assumption used to determine benefit obligation:

Expected return on plan assets	3.8	%	5.5	%	6.0	%	—		—		—

The discount rate used in the determination of pension benefit and OPEB obligations and pension expense was determined based on a review of long-term high-grade bonds.

The expected return on plan assets assumption is based upon an analysis of historical long-term returns for various investment categories, as measured by appropriate indices and forward looking expectations of returns. These indices are weighted based upon the extent to which plan assets are invested in the particular categories in arriving at our determination of a composite expected return.

57

The assumed health care cost trend rate used to calculate 2021 OPEB cost was 6.3% in 2021, grading to 3.7% over approximately 60 years, for participants whose benefits are not provided through HRAs, and 4.5% in 2021 through 2061, then grading to 3.7% after 2061 for participants whose benefits are provided through HRAs. The health care cost trend rate used to calculate December 31, 2021 OPEB obligations was 5.7% in 2022, grading to 3.7% over approximately 60 years, for participants whose benefits are not provided through HRAs, and 4.5% in 2022 through 2061, then grading to 3.7% after 2061 for participants whose benefits are provided through HRAs. This assumption has a significant effect on the amounts reported.

Plan Assets

There have been no changes in the methodologies used during 2021 and 2020. Investments in common and collective trust funds are generally valued based on their respective net asset value (or its equivalent), as a practical expedient to estimate fair value due to the absence of a readily determinable fair value.

The following tables set forth by level, within the fair value hierarchy, the investments at fair value for our company-sponsored pension benefit plans:

	December 31, 2021
(In millions)	Level 1		Investments measured at net asset value		Total
Cash and cash equivalents	$	5.8	$	—	$	5.8
Common and collective trust:
Collective investment funds	—		311.7		311.7
Total investments at fair value	$	5.8	$	311.7	$	317.5

(In millions)	Level 1		Investments measured at net asset value		Total
Cash and cash equivalents	$	2.4	$	—	$	2.4
Common and collective trusts:
Collective investment funds	—		333.5		333.5
Total investments at fair value	$	2.4	$	333.5	$	335.9

We have formal investment policy guidelines for our company-sponsored plans. These guidelines were set by our Benefits Committee, which is comprised of members of our management and has been assigned its fiduciary authority over management of the plan assets by our Board of Directors. The Committee’s duties include periodically reviewing and modifying those investment policy guidelines as necessary and ensuring that the policy is adhered to and the investment objectives are met. The investment policy includes guidelines for specific categories of equity and fixed income securities. Assets are managed by professional investment managers who are expected to achieve a reasonable rate of return over a market cycle. Long-term performance is a fundamental tenet of the policy.

The general policy states that plan assets would be invested to seek the greatest return consistent with the fiduciary character of the pension funds and to allow the plans to meet the need for timely pension benefit payments. The specific investment guidelines stipulate that management is to maintain adequate liquidity for meeting expected benefit payments by reviewing, on a timely basis, contribution and benefit payment levels and appropriately revising long-term and short-term asset allocations. Management takes reasonable and prudent steps to preserve the value of pension fund assets, avoid the risk of large losses and also attempt to preserve the funded status of the plans. Major steps taken to provide this protection included:

58

▪Assets are diversified among various asset classes, such as domestic equities, international equities, fixed income and cash. The long-term asset allocation ranges are as follows:

Domestic equities	5%	-	10%
International equities, including emerging markets	5%	-	10%
Corporate/Government bonds	80%	-	90%
Liquid reserves	—%	-	5%

Periodically, we review the allocations within these ranges to determine what adjustments should be made based on changing economic and market conditions and specific liquidity requirements.

•Assets are managed by professional investment managers and could be invested in separately managed accounts or commingled funds.

▪Assets are not invested in securities rated below BBB- by S&P or Baa3 by Moody’s.

The investment guidelines also require that the individual investment managers are expected to achieve a reasonable rate of return over a market cycle. Emphasis is placed on long-term performance versus short-term market aberrations. Factors considered in determining reasonable rates of return include performance achieved by a diverse cross section of other investment managers, performance of commonly used benchmarks (e.g., Russell 3000 Index, MSCI World ex-U.S. Index, Barclays Capital Long Credit Index), actuarial assumptions for return on plan investments and specific performance guidelines given to individual investment managers.

As of December 31, 2021, eight investment options held substantially all of the pension funds. Plan assets were diversified among the various asset classes within the allocation ranges approved by the Benefits Committee.

In 2021, we did not make any contributions to our qualified pension plans, and we currently do not anticipate making any cash contributions to those plans in 2022. We do not anticipate funding our OPEB plans in 2022 except to pay benefit costs as incurred during the year by plan participants.

Estimated future benefit payments are as follows for the years indicated:

(In millions)	Pension  Benefit Plans		Other Postretirement Employee Benefit Plans
2022	$	20.1	$	5.3
2023	20.1		5.0
2024	20.0		4.8
2025	19.7		4.6
2026	19.4		4.4
2027-2031	92.4		19.9

Multiemployer Defined Benefit Pension Plans

Hourly employees at one of our manufacturing facilities participate in multiemployer defined benefit pension plans: the PACE Industry Union-Management Pension Fund (PIUMPF) which is managed by United Steelworkers (USW), Benefits; and the International Association of Machinist & Aerospace Workers National Pension Fund (IAM NPF). We make contributions to these plans, as well as make contributions to a trust fund established to provide retiree medical benefits for a portion of these employees, which is also managed by USW Benefits. The risks of participating in these multiemployer plans are different from single-employer plans in the following respects:

•Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.

•If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. The number of employers participating in PIUMPF fell from 135 during 2012 to 44 during 2020. We believe that we are now the employer making the largest proportion of total contributions.

•Under applicable federal law, any employer contributing to a multiemployer pension plan that completely ceases participating in the plan while it is underfunded is subject to an assessment of such employer's allocable

59

share of the aggregate unfunded vested benefits of the plan, except when that plan is in "critical" or "critical and declining" status. In certain circumstances, an employer can also be assessed a statutory withdrawal liability for a partial withdrawal from a multiemployer pension plan. Based on information available to us as of December 31, 2021, as well as information provided by PIUMPF and IAM NPF and reviewed by our actuarial consultant, we estimate the aggregate pre-tax liability that we would have incurred if we had completely withdrawn from PIUMPF and IAM NPF in 2021 would have been in excess of $90 million. However, the exact amount of potential exposure could be higher or lower than the estimate, depending on, among other things, the nature and timing of any triggering events and the funded status of PIUMPF and IAM NPF at that time. A withdrawal liability is recorded for accounting purposes when withdrawal is probable and the amount of the withdrawal obligation is reasonably estimable.

Our participation in these plans for the annual period ended December 31, 2021, is outlined in the table below. The “EIN" and "Plan Number” columns provide the Employee Identification Number, or EIN, and the three-digit plan number. The most recent Pension Protection Act, or PPA, zone status available in 2021 and 2020 is for a plan’s year-end as of December 31, 2021 and 2020. The zone status is set under the provisions of the Multiemployer Pension Plan Reform Act of 2014 and is based on information we received from the plans and is certified by each plan's actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent but more than 65 percent funded, and plans in the green zone are at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates plans for which a Funding Improvement Plan, or FIP, or a Rehabilitation Plan, or RP, is either pending or has been implemented as required by the PPA as a measure to correct its underfunded status. The last column lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject.

In 2021, the contribution rate for the IAM NPF plan was $4.00 per hour. In accordance with the Rehabilitation Plan, we began contributing an additional contribution in June 2019. This additional contribution started at 2.5% and will increase 2.5% each year while the Rehabilitation Plan is in effect. Starting June of 2021 our additional contribution increased to 7.75% of our contractual contribution rate. This additional contribution is scheduled to continue and compound each year while the rehabilitation plan remains in effect. In 2021, the contribution rate for PIUMPF was $2.79 per hour. Contribution rates for IAM NPF and PIUMPF were increased as part of the RP in lieu of the legally required surcharge, paid by the employers, to assist the fund’s financial status. We were listed in PIUMPF’s Form 5500 report as providing more than five percent of the total contributions for the years 2020 and 2019. At the date of issuance of our consolidated financial statements, Form 5500 reports for these plans were not available for the 2021 plan year.

Other Benefit Plans

We maintain the Clearwater Paper Corporation Management Deferred Compensation Plan (the Plan). Pursuant to the Plan, certain management employees are eligible to defer up to 50% of their regular salary and up to 10% of their Annual incentives. Each plan participant is fully vested in these contributions. The liability under this plan totaled $4.4 million and $3.2 million at December 31, 2021 and December 31, 2020. The current and long term portions of the liability is included in “Accrued compensation” and “Other long-term obligations” on our Consolidated Balance Sheets.

NOTE 13 Earnings Per Share

Basic earnings (loss) per share are based on the weighted average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents be excluded from the calculation of diluted earnings per share for the periods in which net losses are reported because the effect is anti-dilutive.

The following table reconciles the number of common shares used in calculating the basic and diluted net earnings per share: 

	December 31,

NOTE 14 Stockholders' Equity

PREFERRED STOCK

We are authorized to issue up to 5,000,000 shares of preferred stock at $0.0001 par value. At December 31, 2021, no shares of preferred stock have been issued.

COMMON STOCK PLANS

We have stock-based compensation plans under which stock options and restricted units are granted. At December 31, 2021, approximately 1.1 million shares were available for future issuance under our stock incentive plan.

	For The Years Ended December 31,
(In millions)	2021		2020		2019
Total equity-based compensation expense    (selling, general and administrative and other operating charges, net)	$	9.1	$	10.5	$	4.1
Income tax benefit related to equity-based compensation	2.3		2.7		1.0
Impact on cash flow due to taxes paid related to net share settlement of equity awards	1.7		0.7		0.4
Intrinsic value of options exercised, equity-based liabilities paid, and the fair value of restricted stock units vested	3.7		2.9		2.1

We recognize the compensation costs on a straight-line basis over the requisite service period of the award, which is generally the vesting term of one to three years.

Restricted Stock Units (Time and Performance Vesting)

We grant restricted awards to certain employees. The awards can either be time vested or vested based upon the attainment of certain performance metrics over a certain time period. Performance conditions generally are tied to attainment of certain financial targets such as return on invested capital, free cash flow or other similar measures. Awards granted under our stock incentive plan generally have a performance or vesting period of three years from the date of grant. These awards are eligible to receive dividend equivalent shares.The market value of these grants approximates the fair value. For awards based upon the achievement of performance goals, the award could range from 0% to 200%. A summary of the status of outstanding restricted stock units as of December 31, 2021, and changes during the year, is presented below:

	Time Vested			Performance-based
	Shares	Weighted Average Grant Date Fair Value		Shares	Weighted Average Grant Date Fair Value

1 Forfeited / Canceled performance-based restricted stock units include both shares forfeited due to employees failure to meet requisite service period and also due to failure to meet required performance measures.

The weighted average grant date fair value for restricted stock units granted during the years ended December 31, 2021 and 2020 was $35.70 and $23.46.

As of December 31, 2021, there was $10.5 million of total unrecognized compensation cost related to outstanding restricted stock unit awards. Restricted stock unit cost is expected to be recognized over a weighted average period of 1.9 years for time vested awards and 1.5 years for performance-based awards.

62

Stock Options

Prior to January 1, 2019, we granted options to certain employees. The options were granted at market price at the date of grant and the fair value of the options was estimated using the Black-Scholes option-pricing model (dividend yield ignored). As of December 31, 2021 all outstanding options are fully vested with a contractual term of ten years after the date of grant. A summary of the status of outstanding stock option awards as of December 31, 2021, and changes during the year, is presented below:

	Shares	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value
Outstanding options at December 31, 2020	353,446	$	49.13	5.2	$	—

Expired	(13,180)	51.30
Outstanding options at December 31, 2021	322,546	$	49.64	4.3	$	—
Outstanding and exercisable options at December 31, 2021	322,546	$	49.64	4.3	$	—

Director Awards

Our Board of Directors are eligible to receive awards of phantom common stock units. Annually our outside directors receive phantom stock units as part of their compensation which vest ratably over a one-year period and accrue dividend equivalent shares for any dividends paid to shareholders of our common stock. The vested portion of a director’s phantom share balance is converted to cash using a twenty-day average price of common stock and paid to the director upon their separation from service as a director.

Due to its cash-settlement feature, we account for these awards as liabilities and recognize the equity-based compensation expense or income at the end of each reporting period based on the portion of the award that is vested and the increase or decrease in the value of our common stock. We recorded director equity-based compensation expense for the years ended December 31, 2021, 2020 and 2019 of $1.1 million, $2.9 million and $0.3 million included in “Other operating charges, net” in the Consolidated Statements of Operations.

At December 31, 2021, the liability amounts associated with director equity-based compensation included in "Other long-term obligations" and "Accounts payable and accrued liabilities" on our Consolidated Balance Sheets was $4.3 million and $2.3 million. At December 31, 2020, the liability amounts associated with director equity-based compensation included in "Other long-term obligations" on our Consolidated Balance Sheets was $5.2 million.

NOTE 15 Commitments and Contingencies

SELF INSURANCE

We are primarily self-insured for workers’ compensation and employee health care liability costs. Self-insurance liabilities for workers’ compensation are determined based upon a valuation performed by an actuarial firm. The estimate of future workers’ compensation liabilities incorporates loss development and an estimate associated with incurred but not yet reported claims. These claims are discounted. Self-insurance liabilities for employee health costs are determined actuarially based upon claims filed and estimated claims incurred but not yet reported. These claims are not discounted.

PURCHASE OBLIGATIONS

To help mitigate our exposure to market risk for changes in utility commodity pricing, we use firm price contracts to supply a portion of the natural gas and electricity requirements of our manufacturing facilities, which were reported through "Cost of sales" on our Consolidated Statements of Operations. As of December 31, 2021, these contracts cover approximately 9% of our expected average monthly natural gas and electricity needs at the respective manufacturing facilities through 2022. These contracts qualify for treatment as "normal purchases or normal sales" under authoritative guidance and required no mark-to-market adjustment.

63

We enter into third-party contracts for certain raw materials, including pulp, logs and chemicals, which may extend beyond one year. Such contracts are typically negotiated to ensure availability of certain product specifications at market prices that adjust regularly within reasonable commercial terms. Such agreements may include minimum quantities, but reductions are permitted when economic or business conditions require reduced production containing the respective raw material.

NOTE 16 Segment Information

Our businesses are organized into two reportable operating segments: Pulp and Paperboard and Consumer Products. The reporting segments follow the same accounting policies used for our Consolidated Financial Statements. We evaluate the performance of our business segments based upon net sales and operating income (loss). Certain amounts have been reclassified from the prior year presentation to reflect the realignment of Clearwater Paper’s baled pulp sales to record inter-segment sales at market price and the realignment of outside pulp sales to the producing segment.

Pulp and Paperboard

Our Pulp and Paperboard segment manufactures and markets solid bleached sulfate paperboard for the high-end segment of the packaging industry as well as offers custom sheeting, slitting and cutting of paperboard.

Consumer Products

Our Consumer Products segment manufactures and sells a complete line of at-home tissue products, or retail products, and minor amounts of parent rolls.

ITEM 9A. Controls and Procedures

Evaluation of disclosure controls and procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, or the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of disclosure controls and procedures is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Subject to the limitations noted above, our management, with the participation of our CEO and CFO, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the fiscal year covered by this annual report on Form 10-K. Based on that evaluation, the CEO and CFO have concluded that, as of such date, our disclosure controls and procedures are effective to meet the objective for which they were designed and operate at the reasonable assurance level.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of our management, including our CEO and CFO and with the oversight of the Audit Committee of the Board of Directors, our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework in Internal Control- Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework). Based on our evaluation under the 2013 Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2021.

The effectiveness of our internal control over financial reporting as of December 31, 2021 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report included in this Annual Report on Form 10-K.

Changes in internal control over financial reporting

There were no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors

Clearwater Paper Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited Clearwater Paper Corporation and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes (collectively, the consolidated financial statements), and our report dated February 15, 2022 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

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

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

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.

The balance of each Participant’s Deferred Compensation Account shall be adjusted for earnings and losses commencing with the date as of which any amount is credited to the Deferred Compensation Account. Such earnings or losses during the deferral period for amounts credited to a Participant’s Deferred Compensation Account shall be computed by reference to the rate of return on one or more of the investment alternatives that are available under the 401(k) Plan and which are designated by the Committee as available under this Plan, which shall include a stable value fixed income fund (the “Stable Value Fund”) and an account that is deemed invested in Stock Units (the “Stock Unit Account”) and shall exclude any self- directed brokerage account available under the 401(k) Plan. Each participating Employee may select (in ten percent (10%) increments) which investment alternative(s) will be used for this purpose with respect to his or her deferred Compensation, and the alternative(s) selected need not be the same as the Employee has selected under the 401(k) Plan, but any such selection will apply only prospectively. The Committee shall determine how frequently such selections may be changed. To record adoption of this Amendment, Clearwater Paper Corporation has caused its authorized officer to execute the same.

Accounting Policies [Abstract]

Significant Accounting Policies

Summary of Significant Accounting Policies

NATURE OF OPERATIONS AND BASIS OF PRESENTATION

We are a premier supplier of bleached paperboard and consumer and parent roll tissue. We supply bleached paperboard to quality-conscious printers and packaging converters, and offer services that include custom sheeting, slitting and cutting. We supply private label tissue to major retailers and wholesale distributors, including grocery, club, mass merchants and discount stores.

Unless the context otherwise requires or unless otherwise indicated, references in this report to “Clearwater Paper Corporation,” “we,” “our,” “the Company” and “us” refer to Clearwater Paper Corporation and its subsidiaries.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates.

PRINCIPLES OF CONSOLIDATION

These consolidated financial statements include the financial condition and results of operations of Clearwater Paper Corporation and its wholly-owned subsidiaries. All intercompany transactions and balances between operations within the Company have been eliminated.

CASH, CASH EQUIVALENTS AND RESTRICTED CASH

We consider all highly liquid instruments with maturities of three months or less to be cash equivalents. Cash that is held by a third party and has restrictions on its availability to us is classified as restricted cash. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported on the Consolidated Balance Sheets to the sum of those same amounts shown in our Consolidated Statements of Cash Flows.

	December 31,
(In millions)	2021		2020		2019
Cash and cash equivalents	$	25.2	$	35.9	$	20.0
Restricted cash	—		—		1.4
Restricted cash included in Other assets, net	1.1		1.1		1.0
Total cash, cash equivalents and restricted cash	$	26.2	$	36.9	$	22.4

ACCOUNTS RECEIVABLE

Receivables consist of:

	December 31,
(In millions)	2021		2020
Trade accounts receivable	$	154.1	$	139.0
Allowance for current expected credit losses	(1.4)		(1.6)
Unbilled receivables	7.2		5.1
Taxes receivable	6.1		16.0
Other	1.4		2.1
	$	167.4	$	160.6

INVENTORIES

Our inventories are stated at the lower of net realizable value or current cost using the average cost method.

	December 31,
(In millions)	2021		2020
Logs, chips and sawdust	$	13.7	$	17.2
Pulp	15.9		11.5
Paperboard and tissue products	148.0		137.0
Materials and supplies	100.1		97.7
	$	277.7	$	263.3

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost, including assets acquired under finance lease obligations, and any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Estimated useful lives generally range from 10 to 40 years for land improvements, 10 to 40 years for buildings and improvements and 2 to 25 years for machinery and equipment (includes office and other equipment).

	December 31,
(In millions)	2021		2020
Land and land improvements	$	109.1	$	111.5
Buildings and improvements	452.5		480.1
Machinery and equipment	2,377.5		2,459.2
Construction in progress	22.4		21.8
	2,961.5		3,072.6
Less accumulated depreciation and amortization	(1,879.7)		(1,881.1)
Property, plant and equipment, net	$	1,081.8	$	1,191.5

At December 31, 2021 and 2020, included within property, plant and equipment, net were finance leases of $27.7 million and $26.7 million and associated accumulated depreciation amounts of $15.2 million and $12.7 million.

Depreciation expense totaled $102.0 million, $107.8 million and $108.4 million for the years ended December 31, 2021, 2020 and 2019.

Capitalized interest is charged to and amortized over the lives of the related assets. For the years ended December 31, 2021, 2020 and 2019 capitalized interest expense was $0.3 million, zero, and $5.9 million.

PLANNED MAINTENANCE

We recognize the cost of repair and maintenance activities in the period in which the activity is performed or goods are received under the direct expense method. We perform planned maintenance activities at our facilities periodically and associated expenses are included in cost of sales.

LEASES

Operating lease right-of-use (ROU) assets and liabilities are recognized at the commencement date of a lease based on the present value of lease payments over the lease term. Our leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the ROU assets and liabilities. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles, and leases within supply agreements primarily relate to usage, repairs and maintenance. As the implicit rate is not readily determinable for most of our leases, we apply a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use our unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate. Leases having a lease term of twelve months or less are not recorded on the balance sheet and the related lease expense is

recognized on a straight-line basis over the term of the lease. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases.

See Note 4, "Leases" for further information.

RETIREMENT PLANS AND POSTRETIREMENT BENEFITS

We are required to use actuarial methods and assumptions in the valuation of defined benefit obligations and other postretirement obligations and the determination of expense. Differences between actual and expected results or changes in the values of the obligations and plan assets are not recognized in earnings as they occur but, rather, systematically and gradually over subsequent periods.

See Note 11, "Retirement Plans and Postretirement Benefits" for further information.

INCOME TAXES

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The determination of our provision for income taxes requires significant judgment, the use of estimates, and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in our consolidated financial statements only after determining a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from tax authorities. When facts and circumstances change, we reassess these probabilities and record any changes in the consolidated financial statements as appropriate.

See Note 6, "Income Taxes" for further information.

REVENUE RECOGNITION

We enter into contracts that can include various combinations of tissue and paperboard products, which are generally distinct and accounted for as separate performance obligations.

Generally, revenue is recognized at a point in time upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Transfer of control typically occurs when the title and risk of loss passes to the customer. Shipping terms generally indicate when title and the risk of loss have passed, usually this is upon receipt at our customer's destination. We have elected to treat shipping and handling costs as a fulfillment cost. We typically expense incremental direct costs of obtaining a contract (sales commissions) when incurred because the amortization period is generally 12 months or less. We maintain consignment inventory at a limited number of customer locations. For consigned inventory, we recognize revenue upon transfer of control, which is often in advance of invoicing the customer. These amounts are classified as unbilled receivables in the above detail of accounts receivable.

We provide for trade promotions, customer cash discounts and other deductions, which are considered variable consideration and recorded as a reduction of net sales. Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. Revenue, net of returns and credits, is only recognized to the extent that it is probable that a significant reversal of any incremental revenue will not occur. Judgment associated with forecasted volumes is required to determine the most probable amount of variable consideration to apply as a reduction to net sales. As of December 31, 2021 and 2020, we had $9.2 million and $10.5 million accrued as customer rebates. Revenue is recognized net of any taxes collected from customers.

See Note 16, "Segment Information" for further information, including the disaggregation of revenue by segment, primary geographical market, and major product type.

OTHER OPERATING CHARGES, NET

We classify significant amounts unrelated to ongoing core operating activities as “Other operating charges, net” in the Consolidated Statements of Operations. Such items include, but are not limited to, amounts related to facility closures and related gain (loss) on sale and impairment, restructuring charges (including severance charges), charges to establish and maintain litigation or environmental reserves, gains or losses from settlements with governmental or other organizations and cash settled equity-based compensation to our directors. Due to the nature of these items, amounts in the statement of operations can fluctuate from year to year. The determination of which items are considered significant and unrelated to core operations is based upon management’s judgment.

See Note 9, "Other Operating Charges, net" for a discussion of specific amounts in 2021, 2020 and 2019.

ACCOUNTS RECEIVABLE ARRANGEMENT

During 2019, we entered into an uncommitted supply-chain financing program with a global financial institution under which a specific customer's trade accounts receivable may be acquired, without recourse, by the institution at a discounted rate. Available capacity under this program is dependent on the level of our trade accounts receivable with this customer and the financial institution’s willingness to purchase such receivables. We have no servicing responsibilities under this agreement. This agreement allows us to obtain payment more quickly than under the contractual terms of sale to this customer.

Receivables sold are de-recognized from our Consolidated Balance Sheet. For the years ended December 31, 2021 and 2020, we sold $202.2 million and $256.2 million, of receivables. The proceeds from these sales of receivables are included within operating activities in our Consolidated Statements of Cash Flows. For the years ended December 31, 2021, 2020, and 2019 factoring expense on the sale of receivables was $0.9 million, $1.2 million, and $1.0 million.

ENVIRONMENTAL AND ASSET RETIREMENT OBLIGATIONS

We estimate our environmental and asset retirement obligations based on various assumptions and judgments, the specific nature of which varies in light of the particular facts and circumstances surrounding each liability. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of required investigation, remediation and monitoring activities and the probable cost of these activities. We have accrued only for specific costs related to environmental matters that we have determined are probable and for which an amount can be reasonably estimated. For asset retirement obligations, the liability is accreted to its settlement value and, where appropriate, the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we recognize a gain or loss for any difference between the settlement amount and the liability recorded. Our asset retirement obligation is included in "Other long-term obligations" in the Consolidated Balance Sheets. Our asset retirement obligation reflects the estimated present value of our obligations for capping, closure and post closure cost with respect to landfills, asbestos remediation and other ongoing environmental monitoring. The following table represents the activity associated with our asset retirement obligations.

Accounting Standards Update and Change in Accounting Principle [Abstract]

New Accounting Pronouncements, Policy

Recently Adopted and New Accounting Standards

RECENTLY ADOPTED

In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which removes certain exceptions, such as the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year, and simplifies the accounting for income taxes in areas such as franchise tax (or similar tax) that is partially based on income. The new standard is effective for annual and interim periods beginning after December 15, 2020. This ASU was adopted as of January 1, 2021 and did not have a material impact on our consolidated financial statements.

NEW ACCOUNTING STANDARDS

In November 2021, the FASB issued ASU 2021-10, Disclosures by Business Entities About Government Assistance (Topic 832), which requires disclosures about certain types of government assistance including the nature of the assistance, related accounting policies, and the effect on an entity's financial statements. The new standard is effective for annual periods beginning after December 15, 2021 with prospective or retrospective adoption permitted. We plan to adopt this ASU prospectively and do not believe it will have a material impact on our consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

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. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We are required to classify these financial assets and liabilities into two groups: recurring-measured on a periodic basis and non-recurring-measured on an as needed basis.

There are three levels of inputs that may be used to measure fair value:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities.

Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; or valuations based on models where the significant inputs are observable or can be corroborated by observable market data.

Level 3: Valuations based on models where significant inputs are not observable. Unobservable inputs are used when little or no market data is available and reflect the Company’s own assumptions about the assumptions market participants would use.

Carrying amounts reported on the balance sheets for cash and cash equivalents, restricted cash, receivables and accounts payable approximate fair value due to the short-term maturity of these instruments. See discussion on fair market values for Long-term Debt included within Note 8, "Debt".

We review the carrying values of goodwill and long-lived assets to be held and used for impairment wherever events or changes in circumstances indicate possible impairment. An impairment loss is recognized when a long-lived asset's carrying value is not recoverable and exceeds estimated fair value. See Note 5, "Goodwill and Intangible Assets" for discussion of fair market values for goodwill.

Outstanding definite-lived intangible assets are amortized over their useful lives of 10 years.

We annually evaluate goodwill for possible impairment as of November 1 with additional interim evaluation performed when management believes that it is more likely than not that events or circumstances have occurred that would result in the impairment of a reporting unit’s goodwill. We evaluate our intangible assets for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable.

The gross book value and accumulated amortization of definite lived intangible assets at December 31, 2021 was $34.9 million and $24.1 million. The gross book value and accumulated amortization of definite lived intangible assets at December 31, 2020 was $63.8 million and $50.1 million.

We are subject to corporate level federal and state income taxes in the United States.

IMPACT OF THE CARES ACT

On March 27, 2020, the "Coronavirus Aid, Relief and Economic Security (CARES) Act" was signed. The CARES Act, among other things, included provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carry back periods, alternative minimum tax credit refunds, modifications to net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvements property. During 2020, we recognized a $7.0 million benefit from the provisions of the Act.

INCOME TAX PROVISION (BENEFIT)

UNCERTAIN TAX POSITIONS

The following table provides a roll forward of our unrecognized tax benefits and associated interest and penalties.

(In millions)	Gross Unrecognized Tax Benefits, Excluding Interest and Penalties		Interest and Penalties		Total Gross Unrecognized Tax Benefits

Unrecognized tax benefits net of related deferred tax assets at December 31, 2021, if recognized, would have favorably impacted our effective tax rate by decreasing our tax provision by $5.5 million. For each of the years ended December 31, 2020 and 2019, if recognized, the balance of unrecognized tax benefits would have favorably impacted our effective tax rate by $6.4 million and $3.5 million. We reflect accrued interest related to tax obligations, as well as penalties, in our provision for income taxes. For each of the years ended December 31, 2021, 2020, and 2019, we accrued interest of less than $0.1 million each year in our income tax provision and no penalties in our income tax provision.

We have operations in many states within the U.S. and are subject, at times, to tax audits in these jurisdictions. With a few exceptions, we are no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for years prior to 2015. We expect that the outcome of any examination will not have a material effect on our consolidated financial statements. Although the timing of resolution of audits is not certain, we evaluate all audit issues in the aggregate, along with the expiration of applicable statutes of limitations, and estimate that it is reasonably possible the total gross unrecognized tax benefits could decrease by approximately $2.6 million within the next 12 months.

Deferred debt costs are amortized over the life of the related debt using a straight line basis which approximates the effective interest method. These costs are a direct deduction from the carrying amount related to the debt liability. If the debt is retired early, the related unamortized deferred debt costs are expensed in the period the debt is retired to debt retirement costs.

We amortized deferred debt costs of $1.8 million, $2.1 million and $2.0 million for the years ended December 31, 2021, 2020 and 2019. Included in these amortized amounts are deferred debt costs associated with our current line of credit, which is recorded within "Other current assets" and "Other assets, net" on our Consolidated Balance Sheets.

During 2020, in connection with the issuance of the 2020 Notes, we redeemed the 2013 Notes in full. This redemption resulted in a loss on early debt retirement of $3.2 million consisting of $1.2 million related to the write off of unamortized debt costs along with the premium on debt redemption of $2.1 million.

The fair value of our debt as of December 31 is included in the following table:

TERM LOAN AND ABL CREDIT AGREEMENTS

On July 26, 2019, we entered into credit agreements with several lenders and JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent, which included (a) a $300 million Term Loan Credit Agreement and (b) a $250 million asset based lending (ABL) Credit Agreement (collectively referred to as the Credit Agreements). At closing, the Term Loan Credit Agreement was fully advanced and $58.0 million was drawn under the ABL Credit Agreement, proceeds of which were used to refinance and terminate our: (a) $200 million credit agreement dated October 31, 2016, as amended, with Wells Fargo Bank, National Association (Wells Fargo), as administrative agent, and the lenders party thereto, of which $135.0 million was outstanding and (b) the $200 million credit agreement dated October 31, 2016, as amended, with Northwest Farm Credit Services, PCA, (Farm Credit) as administrative agent, and the lenders party thereto, of which $200.0 million was outstanding (the Prior Credit Agreements); pay fees and expenses in connection with the Credit Agreements; and for working capital purposes.

In conjunction with the termination of the Prior Credit Agreements, of which the $200 million credit agreement with Wells Fargo was treated as a debt modification, debt retirement costs consisted of $1.7 million in breakage fees and $1.0 million in unamortized debt issuance costs. Unamortized debt issuance costs of $1.6 million, related to the debt modification, are being amortized over the remaining term of the ABL Credit Agreement. We incurred additional debt issuance costs of $7.3 million, which were allocated and will be amortized over the respective terms of the Credit Agreements.

The Credit Agreements contain certain customary representations, warranties, and affirmative and negative covenants of us and our subsidiaries that restrict us and our subsidiaries’ ability to take certain actions, including, incurrence of indebtedness, creation of liens, mergers or consolidations, dispositions of assets, repurchase or redemption of capital stock and certain types of indebtedness, making certain investments, entering into certain transactions with affiliates or changing the nature of our business. At December 31, 2021, we were in compliance with the Credit Agreements.

Term Loan Credit Agreement

The Term Loan Credit Agreement matures on July 26, 2026. We are required to repay the aggregate outstanding principal amount in quarterly installments in an aggregate amount for each such date equal to the aggregate principal amount of the initial loan amount (as such amount may be adjusted pursuant to the prepayment provisions of the Term Loan Credit Agreement) multiplied by 0.25%. Through December 31, 2021, we have made voluntary principal prepayments of the Term Loan Credit Agreement of $79.3 million, and accordingly we have fulfilled all scheduled payments through maturity. In connection with the voluntary repayments, we recorded early debt retirement costs related to the expensing of deferred debt costs of $1.0 million and $2.6 million for the periods ended December 31, 2021 and December 31, 2020.

In addition, we must make mandatory prepayments of principal under the Term Loan Credit Agreement upon the occurrence of certain specified events, including certain asset sales (subject to customary reinvestment rights), debt issuances not permitted under the Term Loan Credit Agreement, and based on a percentage, which may vary from 0% to 50% depending on our secured leverage ratio, of annual excess cash flows in excess of certain threshold amounts, less any voluntary prepayments under the Term Loan Credit Agreement. Any remaining outstanding principal balance under the Term Loan Credit Agreement is repayable on the maturity date. Amounts repaid or prepaid by us with respect to the loans under the Term Loan Credit Agreement cannot be reborrowed.

We may add one or more incremental term loan facilities to the Term Loan Credit Agreement, subject to obtaining commitments from any participating lenders and certain other conditions, in an amount not to exceed (1) $100 million, plus (2) the amount of all voluntary prepayments of the Term Loan Credit Agreement (other than prepayments funded with long-term indebtedness), plus (3) an additional amount, so long as after giving effect to the incurrence of such additional amount, our pro forma first lien secured leverage ratio would not exceed 2.00x to 1.00x. At December 31, 2021 our first lien secured ratio was 0.24x. Under the Term Loan Credit Agreement, loans generally may bear interest

based on LIBOR or an annual base rate, as applicable, plus, in each case, an applicable margin. When our leverage ratio is (i) less than or equal to 4.25 to 1.00, the margin is 3.00% per annum in the case of LIBOR loans and 2.00% per annum in the case of annual base rate loans and (ii) greater than 4.25 to 1.00, the margin is 3.25% per annum in the case of LIBOR loans and 2.25% per annum in the case of annual base rate loans. At December 31, 2021, our leverage ratio was 3.4x and therefore our applicable margin on LIBOR loans was 3.00%.

ABL Credit Agreement

The ABL Credit Agreement matures on July 26, 2024 and includes a $250.0 million revolving loan commitment, subject to borrowing base limitations based on a percentage of applicable eligible receivables and eligible inventory. Based upon our Consolidated Balance Sheets as of December 31, 2021, our eligible receivables and inventory supported up to $243.6 million availability under the line of which no borrowings were outstanding and $3.6 million was utilized to issue letters of credit. We may, at our option, prepay any borrowings under the ABL Credit Agreement, in whole or in part, at any time and from time to time without premium or penalty (except in certain circumstances). Borrowings under the ABL Credit Agreement are also subject to mandatory prepayment in certain circumstances, including in the event that borrowings exceed applicable borrowing base limits. We may also increase commitments under the ABL Credit Agreement in an aggregate principal amount of up to $100 million, subject to obtaining commitments from any participating lenders and certain other conditions.

Under the ABL Credit Agreement, loans may bear interest based on LIBOR or an annual base rate, as applicable, plus, in each case, an applicable margin that is based on availability, as calculated under the ABL Credit Agreement that may vary from 1.25% per annum to 1.75% per annum in the case of LIBOR loans and 0.25% per annum to 0.75% per annum in the case of annual base rate loans. In addition, a commitment fee based on unused availability is also payable which may vary from 0.25% per annum to 0.375% per annum.

The ABL Credit Agreement also contains a financial covenant, which requires us to maintain a consolidated fixed charge coverage ratio of not less than 1.10x to 1.00x, provided that the financial covenant under the ABL Credit Agreement is only applicable when unused availability falls below $25 million. As of December 31, 2021, our fixed charge coverage ratio was approximately 3.56x. Our ability to utilize our ABL Credit Agreement could be limited in the future by our bond indentures which have limitations on liens.

2014 NOTES

In 2014, we issued $300 million aggregate principal amount of senior notes (2014 Notes), due February 1, 2025, with an interest rate of 5.375%.

The 2014 Notes are guaranteed by all of our direct and indirect domestic subsidiaries, as well as any future direct and indirect domestic subsidiaries that do not constitute an immaterial subsidiary under the indenture governing the 2014 Notes. The 2014 Notes are equal in right of payment with all other existing and future unsecured senior indebtedness and are senior in right of payment to any future subordinated indebtedness. The 2014 Notes are effectively subordinated to all of our existing and future secured indebtedness, including borrowings under our Term Loan and ABL Credit Agreements. The terms of the 2014 Notes limit our ability and the ability of any restricted subsidiaries to incur certain liens, engage in sale and leaseback transactions and consolidate, merge with, or convey, transfer or lease substantially all of our or their assets to another person.

We may, on any one or more occasions, redeem all or a part of the 2014 Notes, upon not less than 30 days nor more than 60 days' notice, at a redemption price equal to 100% of the principal amount of the 2014 Notes redeemed, plus the applicable premium as of, and accrued and unpaid interest, to the date of redemption. In addition, we may be required to make an offer to purchase the 2014 Notes upon the sale of certain assets or upon a change of control.

2020 NOTES

In 2020, we issued $275 million aggregate principal amount of senior notes (2020 Notes) due August 2028 with an interest rate of 4.75%.

The 2020 Notes are unsecured and effectively subordinated to all of the Company’s existing and future secured debt, including borrowings under its existing credit facilities. The 2020 Notes are guaranteed on an unsecured basis by each of the Company’s existing direct and indirect domestic subsidiaries, and will be guaranteed by each of the Company’s future direct and indirect domestic subsidiaries, subject to certain exceptions. If the Company is unable to make payments on the 2020 Notes when they are due, each Guarantor is obligated to make such payments.

The Indenture contains covenants that, among other things, limit our ability and the ability of any of our subsidiaries to (i) enter into sale leaseback transactions, (ii) incur liens and (iii) consolidate, merge or sell all or substantially all of our assets. In addition, the Indenture requires, among other things, we provide certain reports to holders of the 2020 Notes. These covenants are subject to a number of exceptions, limitations and qualifications as set forth in the Indenture.

We may redeem all or a portion of the 2020 Notes at specified redemption prices plus accrued and unpaid interest. In addition, we may be required to make an offer to purchase the 2020 Notes upon the sale of certain assets and upon a change in control.

Savings, Pension and Other Postretirement Employee Benefit Plans

12 Months Ended

Dec. 31, 2021

Retirement Benefits [Abstract]

Savings, Pension and Other Postretirement Employee Benefit Plans

Postretirement Benefits

Certain of our employees are eligible to participate in defined contribution savings and defined benefit postretirement plans. These include 401(k) savings plans, defined benefit pension plans including company-sponsored and multiemployer plans, and other postretirement employee benefit (OPEB) plans.

401(k) Savings Plans

Substantially all of our employees are eligible to participate in 401(k) savings plans, which include a company match component. As of December 31, 2021 our contributions may be up to 7.7% for U.S. salaried and non-union hourly employees, consisting of a match of up to 4.2% of allowable contributions and an automatic employer contribution of 3.5%. Contributions associated with our union employees are based upon negotiated agreements. In 2021, 2020 and 2019, we recorded expense of $16.4 million, $17.3 million, and $15.3 million related to employer contributions to the 401(k) plans.

Company-Sponsored Defined Benefit Pension and OPEB Plans

A portion of our salaried and hourly employees are covered by company-sponsored noncontributory defined benefit pension plans. We provide retiree health care and life insurance plans, which cover certain salaried and hourly employees. Retiree health care benefits for Medicare eligible participants over the age of 65 are provided through Health Reimbursement Accounts, or HRA's. Benefits for retirees under the age of 65 are provided under our company-sponsored health care plans, which require retiree contributions and contain other cost-sharing features. The retiree life insurance plans are primarily noncontributory.

We also maintain a Salaried Supplemental Benefit Plan, an unfunded, non-qualified defined benefit plan intended to provide supplemental retirement benefits to certain executives. Benefits in the Salaried Supplemental Benefit Plan are generally provided to restore benefits or company contributions that are reduced under the Company sponsored qualified plans due to the limits of Section 401(a)(17) or 415 of the Code. The plan is composed of a defined benefit portion and a defined contribution portion. The defined benefit portion of the plan was frozen on December 31, 2011 (the date on which all benefit accruals under the Salaried Retirement Plan were frozen) and as of December 31, 2021, we had two active employees under this portion. We paid benefits of $0.4 million associated with the defined benefit portion of the plan in 2021. The defined contribution portion of this liability totaled $1.4 million and $2.4 million at December 31, 2021 and December 31, 2020. The current and long term portions of the liability is included in “Accrued compensation” and “Other long-term obligations” on our Consolidated Balance Sheets. The defined benefit portion is included in the pension benefit plans tables below.

Pension and Other Postretirement Employee Benefit Plans

The following table shows the changes in the benefit obligation, plan assets and funded status for 2021 and 2020 for both the pension benefit plans and the other postretirement employee benefit plans.

	Pension Benefit Plans				Other Postretirement Employee Benefit Plans

Amounts recognized in accumulated other comprehensive loss (pre-tax):
Net actuarial loss (gain)	$	57.6	$	73.3	$	5.8	$	5.9

The benefit obligation for our pension benefits is the projected benefit obligation based upon credited service as of the measurement date.

The December 31, 2021 pension funded status was favorably affected by an increase in the discount rate, partially offset by lower than expected asset returns. The December 31, 2021 OPEB benefit obligation decreased as of December 31, 2021 due to an increase in the discount rate, decrease in claim costs assumptions, and the continued payment of benefits, partially offset by demographic changes.

Information as of December 31 for certain pension plans included above with accumulated benefit obligations in excess of plan assets were as follows:

(In millions)	2021		2020
Projected benefit obligation	$	173.9	$	188.7
Accumulated benefit obligation	173.9		188.7
Fair value of plan assets	166.4		176.2

Net Periodic Cost

Service cost is the actuarial present value of benefits attributed by the plans’ benefit formula to services rendered by employees during the year. Interest cost represents the increase in the projected benefit obligation, which is a discounted amount, due to the passage of time. The expected return on plan assets reflects the computed amount of current-year earnings from the investment of plan assets using an estimated long-term rate of return.

	Pension Benefit Plans						Other Postretirement Employee Benefit Plans
(In millions)	2021		2020		2019		2021		2020		2019
Service cost	$	1.8	$	2.2	$	2.4	$	0.4	$	0.1	$	0.1
Interest cost	8.4		10.4		12.4		2.0		2.3		2.8

Net periodic cost (income)	$	9.9	$	7.5	$	5.6	$	2.7	$	2.4	$	2.6

The components of net periodic pension expense other than the Service cost component are included in "Other non-operating expense" in the Consolidated Statements of Operations. During 2021, 2020, and 2019, $2.0 million, $1.9 million and $1.5 million of net periodic pension and OPEB costs were charged to "Cost of sales" and $0.2 million, $0.5 million and $1.0 million were charged to "Selling, general and administrative expenses," in the accompanying Consolidated Statements of Operations.

Assumptions:	Pension Benefit Plans						Other Postretirement Employee Benefit Plans
	2021		2020		2019		2021		2020		2019
Actuarial assumption used to determine benefit obligation:

Expected return on plan assets	3.8	%	5.5	%	6.0	%	—		—		—

The discount rate used in the determination of pension benefit and OPEB obligations and pension expense was determined based on a review of long-term high-grade bonds.

The expected return on plan assets assumption is based upon an analysis of historical long-term returns for various investment categories, as measured by appropriate indices and forward looking expectations of returns. These indices are weighted based upon the extent to which plan assets are invested in the particular categories in arriving at our determination of a composite expected return.

The assumed health care cost trend rate used to calculate 2021 OPEB cost was 6.3% in 2021, grading to 3.7% over approximately 60 years, for participants whose benefits are not provided through HRAs, and 4.5% in 2021 through 2061, then grading to 3.7% after 2061 for participants whose benefits are provided through HRAs. The health care cost trend rate used to calculate December 31, 2021 OPEB obligations was 5.7% in 2022, grading to 3.7% over approximately 60 years, for participants whose benefits are not provided through HRAs, and 4.5% in 2022 through 2061, then grading to 3.7% after 2061 for participants whose benefits are provided through HRAs. This assumption has a significant effect on the amounts reported.

Plan Assets

There have been no changes in the methodologies used during 2021 and 2020. Investments in common and collective trust funds are generally valued based on their respective net asset value (or its equivalent), as a practical expedient to estimate fair value due to the absence of a readily determinable fair value.

The following tables set forth by level, within the fair value hierarchy, the investments at fair value for our company-sponsored pension benefit plans:

	December 31, 2021
(In millions)	Level 1		Investments measured at net asset value		Total
Cash and cash equivalents	$	5.8	$	—	$	5.8
Common and collective trust:
Collective investment funds	—		311.7		311.7
Total investments at fair value	$	5.8	$	311.7	$	317.5

	December 31, 2020
(In millions)	Level 1		Investments measured at net asset value		Total
Cash and cash equivalents	$	2.4	$	—	$	2.4
Common and collective trusts:
Collective investment funds	—		333.5		333.5
Total investments at fair value	$	2.4	$	333.5	$	335.9

We have formal investment policy guidelines for our company-sponsored plans. These guidelines were set by our Benefits Committee, which is comprised of members of our management and has been assigned its fiduciary authority over management of the plan assets by our Board of Directors. The Committee’s duties include periodically reviewing and modifying those investment policy guidelines as necessary and ensuring that the policy is adhered to and the investment objectives are met. The investment policy includes guidelines for specific categories of equity and fixed income securities. Assets are managed by professional investment managers who are expected to achieve a reasonable rate of return over a market cycle. Long-term performance is a fundamental tenet of the policy.

The general policy states that plan assets would be invested to seek the greatest return consistent with the fiduciary character of the pension funds and to allow the plans to meet the need for timely pension benefit payments. The specific investment guidelines stipulate that management is to maintain adequate liquidity for meeting expected benefit payments by reviewing, on a timely basis, contribution and benefit payment levels and appropriately revising long-term and short-term asset allocations. Management takes reasonable and prudent steps to preserve the value of pension fund assets, avoid the risk of large losses and also attempt to preserve the funded status of the plans. Major steps taken to provide this protection included:

▪Assets are diversified among various asset classes, such as domestic equities, international equities, fixed income and cash. The long-term asset allocation ranges are as follows:

Domestic equities	5%	-	10%
International equities, including emerging markets	5%	-	10%
Corporate/Government bonds	80%	-	90%
Liquid reserves	—%	-	5%

Periodically, we review the allocations within these ranges to determine what adjustments should be made based on changing economic and market conditions and specific liquidity requirements.

•Assets are managed by professional investment managers and could be invested in separately managed accounts or commingled funds.

▪Assets are not invested in securities rated below BBB- by S&P or Baa3 by Moody’s.

The investment guidelines also require that the individual investment managers are expected to achieve a reasonable rate of return over a market cycle. Emphasis is placed on long-term performance versus short-term market aberrations. Factors considered in determining reasonable rates of return include performance achieved by a diverse cross section of other investment managers, performance of commonly used benchmarks (e.g., Russell 3000 Index, MSCI World ex-U.S. Index, Barclays Capital Long Credit Index), actuarial assumptions for return on plan investments and specific performance guidelines given to individual investment managers.

As of December 31, 2021, eight investment options held substantially all of the pension funds. Plan assets were diversified among the various asset classes within the allocation ranges approved by the Benefits Committee.

In 2021, we did not make any contributions to our qualified pension plans, and we currently do not anticipate making any cash contributions to those plans in 2022. We do not anticipate funding our OPEB plans in 2022 except to pay benefit costs as incurred during the year by plan participants.

Estimated future benefit payments are as follows for the years indicated:

(In millions)	Pension  Benefit Plans		Other Postretirement Employee Benefit Plans
2022	$	20.1	$	5.3
2023	20.1		5.0
2024	20.0		4.8
2025	19.7		4.6
2026	19.4		4.4
2027-2031	92.4		19.9

Multiemployer Defined Benefit Pension Plans

Hourly employees at one of our manufacturing facilities participate in multiemployer defined benefit pension plans: the PACE Industry Union-Management Pension Fund (PIUMPF) which is managed by United Steelworkers (USW), Benefits; and the International Association of Machinist & Aerospace Workers National Pension Fund (IAM NPF). We make contributions to these plans, as well as make contributions to a trust fund established to provide retiree medical benefits for a portion of these employees, which is also managed by USW Benefits. The risks of participating in these multiemployer plans are different from single-employer plans in the following respects:

•Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.

•If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. The number of employers participating in PIUMPF fell from 135 during 2012 to 44 during 2020. We believe that we are now the employer making the largest proportion of total contributions.

•Under applicable federal law, any employer contributing to a multiemployer pension plan that completely ceases participating in the plan while it is underfunded is subject to an assessment of such employer's allocable

share of the aggregate unfunded vested benefits of the plan, except when that plan is in "critical" or "critical and declining" status. In certain circumstances, an employer can also be assessed a statutory withdrawal liability for a partial withdrawal from a multiemployer pension plan. Based on information available to us as of December 31, 2021, as well as information provided by PIUMPF and IAM NPF and reviewed by our actuarial consultant, we estimate the aggregate pre-tax liability that we would have incurred if we had completely withdrawn from PIUMPF and IAM NPF in 2021 would have been in excess of $90 million. However, the exact amount of potential exposure could be higher or lower than the estimate, depending on, among other things, the nature and timing of any triggering events and the funded status of PIUMPF and IAM NPF at that time. A withdrawal liability is recorded for accounting purposes when withdrawal is probable and the amount of the withdrawal obligation is reasonably estimable.

Our participation in these plans for the annual period ended December 31, 2021, is outlined in the table below. The “EIN" and "Plan Number” columns provide the Employee Identification Number, or EIN, and the three-digit plan number. The most recent Pension Protection Act, or PPA, zone status available in 2021 and 2020 is for a plan’s year-end as of December 31, 2021 and 2020. The zone status is set under the provisions of the Multiemployer Pension Plan Reform Act of 2014 and is based on information we received from the plans and is certified by each plan's actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent but more than 65 percent funded, and plans in the green zone are at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates plans for which a Funding Improvement Plan, or FIP, or a Rehabilitation Plan, or RP, is either pending or has been implemented as required by the PPA as a measure to correct its underfunded status. The last column lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject.

In 2021, the contribution rate for the IAM NPF plan was $4.00 per hour. In accordance with the Rehabilitation Plan, we began contributing an additional contribution in June 2019. This additional contribution started at 2.5% and will increase 2.5% each year while the Rehabilitation Plan is in effect. Starting June of 2021 our additional contribution increased to 7.75% of our contractual contribution rate. This additional contribution is scheduled to continue and compound each year while the rehabilitation plan remains in effect. In 2021, the contribution rate for PIUMPF was $2.79 per hour. Contribution rates for IAM NPF and PIUMPF were increased as part of the RP in lieu of the legally required surcharge, paid by the employers, to assist the fund’s financial status. We were listed in PIUMPF’s Form 5500 report as providing more than five percent of the total contributions for the years 2020 and 2019. At the date of issuance of our consolidated financial statements, Form 5500 reports for these plans were not available for the 2021 plan year.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings (loss) per share are based on the weighted average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents be excluded from the calculation of diluted earnings per share for the periods in which net losses are reported because the effect is anti-dilutive.

The following table reconciles the number of common shares used in calculating the basic and diluted net earnings per share: 

	December 31,
(In thousands - except per share data)	2021		2020		2019
Basic average common shares outstanding1	16,767		16,569		16,533

Diluted net income (loss) per common share	$	(1.67)	$	4.61	$	(0.34)

Anti-dilutive shares excluded from the calculation were 0.7 million, 0.5 million and 1.0 million for the years ended December 31, 2021, 2020 and 2019.

1 Basic average common shares outstanding include restricted stock awards that are fully vested, but are deferred for future issuance. See Note 14 "Stockholders' Equity" for further discussion.

Stockholders' Equity

PREFERRED STOCK

We are authorized to issue up to 5,000,000 shares of preferred stock at $0.0001 par value. At December 31, 2021, no shares of preferred stock have been issued.

COMMON STOCK PLANS

We have stock-based compensation plans under which stock options and restricted units are granted. At December 31, 2021, approximately 1.1 million shares were available for future issuance under our stock incentive plan.

	For The Years Ended December 31,
(In millions)	2021		2020		2019

We recognize the compensation costs on a straight-line basis over the requisite service period of the award, which is generally the vesting term of one to three years.

Restricted Stock Units (Time and Performance Vesting)

We grant restricted awards to certain employees. The awards can either be time vested or vested based upon the attainment of certain performance metrics over a certain time period. Performance conditions generally are tied to attainment of certain financial targets such as return on invested capital, free cash flow or other similar measures. Awards granted under our stock incentive plan generally have a performance or vesting period of three years from the date of grant.

The weighted average grant date fair value for restricted stock units granted during the years ended December 31, 2021 and 2020 was $35.70 and $23.46.

As of December 31, 2021, there was $10.5 million of total unrecognized compensation cost related to outstanding restricted stock unit awards. Restricted stock unit cost is expected to be recognized over a weighted average period of 1.9 years for time vested awards and 1.5 years for performance-based awards.

Stock Options

Prior to January 1, 2019, we granted options to certain employees. The options were granted at market price at the date of grant and the fair value of the options was estimated using the Black-Scholes option-pricing model (dividend yield ignored). As of December 31, 2021 all outstanding options are fully vested with a contractual term of ten years after the date of grant. A summary of the status of outstanding stock option awards as of December 31, 2021, and changes during the year, is presented below:

Director Awards

Our Board of Directors are eligible to receive awards of phantom common stock units. Annually our outside directors receive phantom stock units as part of their compensation which vest ratably over a one-year period and accrue dividend equivalent shares for any dividends paid to shareholders of our common stock. The vested portion of a director’s phantom share balance is converted to cash using a twenty-day average price of common stock and paid to the director upon their separation from service as a director.

Due to its cash-settlement feature, we account for these awards as liabilities and recognize the equity-based compensation expense or income at the end of each reporting period based on the portion of the award that is vested and the increase or decrease in the value of our common stock. We recorded director equity-based compensation expense for the years ended December 31, 2021, 2020 and 2019 of $1.1 million, $2.9 million and $0.3 million included in “Other operating charges, net” in the Consolidated Statements of Operations.

At December 31, 2021, the liability amounts associated with director equity-based compensation included in "Other long-term obligations" and "Accounts payable and accrued liabilities" on our Consolidated Balance Sheets was $4.3 million and $2.3 million. At December 31, 2020, the liability amounts associated with director equity-based compensation included in "Other long-term obligations" on our Consolidated Balance Sheets was $5.2 million.

Commitments and Contingencies

SELF INSURANCE

We are primarily self-insured for workers’ compensation and employee health care liability costs. Self-insurance liabilities for workers’ compensation are determined based upon a valuation performed by an actuarial firm. The estimate of future workers’ compensation liabilities incorporates loss development and an estimate associated with incurred but not yet reported claims. These claims are discounted. Self-insurance liabilities for employee health costs are determined actuarially based upon claims filed and estimated claims incurred but not yet reported. These claims are not discounted.

PURCHASE OBLIGATIONS

To help mitigate our exposure to market risk for changes in utility commodity pricing, we use firm price contracts to supply a portion of the natural gas and electricity requirements of our manufacturing facilities, which were reported through "Cost of sales" on our Consolidated Statements of Operations. As of December 31, 2021, these contracts cover approximately 9% of our expected average monthly natural gas and electricity needs at the respective manufacturing facilities through 2022. These contracts qualify for treatment as "normal purchases or normal sales" under authoritative guidance and required no mark-to-market adjustment.

We enter into third-party contracts for certain raw materials, including pulp, logs and chemicals, which may extend beyond one year. Such contracts are typically negotiated to ensure availability of certain product specifications at market prices that adjust regularly within reasonable commercial terms. Such agreements may include minimum quantities, but reductions are permitted when economic or business conditions require reduced production containing the respective raw material.

Segment Reporting [Abstract]

Segment Information

Segment Information

Our businesses are organized into two reportable operating segments: Pulp and Paperboard and Consumer Products. The reporting segments follow the same accounting policies used for our Consolidated Financial Statements. We evaluate the performance of our business segments based upon net sales and operating income (loss). Certain amounts have been reclassified from the prior year presentation to reflect the realignment of Clearwater Paper’s baled pulp sales to record inter-segment sales at market price and the realignment of outside pulp sales to the producing segment.

Pulp and Paperboard

Our Pulp and Paperboard segment manufactures and markets solid bleached sulfate paperboard for the high-end segment of the packaging industry as well as offers custom sheeting, slitting and cutting of paperboard.

Consumer Products

Our Consumer Products segment manufactures and sells a complete line of at-home tissue products, or retail products, and minor amounts of parent rolls.

The table below presents information about our reportable segments:

Accounting Policies [Abstract]

Use of Estimates, Policy

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates.

Consolidation, Policy

PRINCIPLES OF CONSOLIDATIONThese consolidated financial statements include the financial condition and results of operations of Clearwater Paper Corporation and its wholly-owned subsidiaries. All intercompany transactions and balances between operations within the Company have been eliminated.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy

CASH, CASH EQUIVALENTS AND RESTRICTED CASH We consider all highly liquid instruments with maturities of three months or less to be cash equivalents. Cash that is held by a third party and has restrictions on its availability to us is classified as restricted cash. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported on the Consolidated Balance Sheets to the sum of those same amounts shown in our Consolidated Statements of Cash Flows.

Property, Plant and Equipment, Policy

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost, including assets acquired under finance lease obligations, and any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Estimated useful lives generally range from 10 to 40 years for land improvements, 10 to 40 years for buildings and improvements and 2 to 25 years for machinery and equipment (includes office and other equipment).

	December 31,

At December 31, 2021 and 2020, included within property, plant and equipment, net were finance leases of $27.7 million and $26.7 million and associated accumulated depreciation amounts of $15.2 million and $12.7 million.

Depreciation expense totaled $102.0 million, $107.8 million and $108.4 million for the years ended December 31, 2021, 2020 and 2019.

Capitalized interest is charged to and amortized over the lives of the related assets. For the years ended December 31, 2021, 2020 and 2019 capitalized interest expense was $0.3 million, zero, and $5.9 million.

PLANNED MAINTENANCE

We recognize the cost of repair and maintenance activities in the period in which the activity is performed or goods are received under the direct expense method. We perform planned maintenance activities at our facilities periodically and associated expenses are included in cost of sales.

Lessee, Leases [Policy Text Block]

LEASES

Operating lease right-of-use (ROU) assets and liabilities are recognized at the commencement date of a lease based on the present value of lease payments over the lease term. Our leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the ROU assets and liabilities. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles, and leases within supply agreements primarily relate to usage, repairs and maintenance. As the implicit rate is not readily determinable for most of our leases, we apply a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use our unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate. Leases having a lease term of twelve months or less are not recorded on the balance sheet and the related lease expense is

recognized on a straight-line basis over the term of the lease. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases.

See Note 4, "Leases" for further information.

Pension and Other Postretirement Plans, Policy

RETIREMENT PLANS AND POSTRETIREMENT BENEFITS

We are required to use actuarial methods and assumptions in the valuation of defined benefit obligations and other postretirement obligations and the determination of expense. Differences between actual and expected results or changes in the values of the obligations and plan assets are not recognized in earnings as they occur but, rather, systematically and gradually over subsequent periods.

See Note 11, "Retirement Plans and Postretirement Benefits" for further information.

Income Tax, Policy

INCOME TAXES

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The determination of our provision for income taxes requires significant judgment, the use of estimates, and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in our consolidated financial statements only after determining a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from tax authorities. When facts and circumstances change, we reassess these probabilities and record any changes in the consolidated financial statements as appropriate.

See Note 6, "Income Taxes" for further information.

Revenue

REVENUE RECOGNITION

We enter into contracts that can include various combinations of tissue and paperboard products, which are generally distinct and accounted for as separate performance obligations.

Generally, revenue is recognized at a point in time upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Transfer of control typically occurs when the title and risk of loss passes to the customer. Shipping terms generally indicate when title and the risk of loss have passed, usually this is upon receipt at our customer's destination. We have elected to treat shipping and handling costs as a fulfillment cost. We typically expense incremental direct costs of obtaining a contract (sales commissions) when incurred because the amortization period is generally 12 months or less. We maintain consignment inventory at a limited number of customer locations. For consigned inventory, we recognize revenue upon transfer of control, which is often in advance of invoicing the customer. These amounts are classified as unbilled receivables in the above detail of accounts receivable.

We provide for trade promotions, customer cash discounts and other deductions, which are considered variable consideration and recorded as a reduction of net sales. Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. Revenue, net of returns and credits, is only recognized to the extent that it is probable that a significant reversal of any incremental revenue will not occur. Judgment associated with forecasted volumes is required to determine the most probable amount of variable consideration to apply as a reduction to net sales. As of December 31, 2021 and 2020, we had $9.2 million and $10.5 million accrued as customer rebates. Revenue is recognized net of any taxes collected from customers.

See Note 16, "Segment Information" for further information, including the disaggregation of revenue by segment, primary geographical market, and major product type.

Other Operating Charges and Credits, Policy [Policy Text Block]

OTHER OPERATING CHARGES, NET

We classify significant amounts unrelated to ongoing core operating activities as “Other operating charges, net” in the Consolidated Statements of Operations. Such items include, but are not limited to, amounts related to facility closures and related gain (loss) on sale and impairment, restructuring charges (including severance charges), charges to establish and maintain litigation or environmental reserves, gains or losses from settlements with governmental or other organizations and cash settled equity-based compensation to our directors. Due to the nature of these items, amounts in the statement of operations can fluctuate from year to year. The determination of which items are considered significant and unrelated to core operations is based upon management’s judgment.

See Note 9, "Other Operating Charges, net" for a discussion of specific amounts in 2021, 2020 and 2019.

Financing Receivable [Policy Text Block]

ACCOUNTS RECEIVABLE ARRANGEMENT

During 2019, we entered into an uncommitted supply-chain financing program with a global financial institution under which a specific customer's trade accounts receivable may be acquired, without recourse, by the institution at a discounted rate. Available capacity under this program is dependent on the level of our trade accounts receivable with this customer and the financial institution’s willingness to purchase such receivables. We have no servicing responsibilities under this agreement. This agreement allows us to obtain payment more quickly than under the contractual terms of sale to this customer.

Receivables sold are de-recognized from our Consolidated Balance Sheet. For the years ended December 31, 2021 and 2020, we sold $202.2 million and $256.2 million, of receivables. The proceeds from these sales of receivables are included within operating activities in our Consolidated Statements of Cash Flows. For the years ended December 31, 2021, 2020, and 2019 factoring expense on the sale of receivables was $0.9 million, $1.2 million, and $1.0 million.

Asset Retirement Obligation and Environmental Cost

ENVIRONMENTAL AND ASSET RETIREMENT OBLIGATIONS

We estimate our environmental and asset retirement obligations based on various assumptions and judgments, the specific nature of which varies in light of the particular facts and circumstances surrounding each liability. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of required investigation, remediation and monitoring activities and the probable cost of these activities. We have accrued only for specific costs related to environmental matters that we have determined are probable and for which an amount can be reasonably estimated. For asset retirement obligations, the liability is accreted to its settlement value and, where appropriate, the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we recognize a gain or loss for any difference between the settlement amount and the liability recorded. Our asset retirement obligation is included in "Other long-term obligations" in the Consolidated Balance Sheets. Our asset retirement obligation reflects the estimated present value of our obligations for capping, closure and post closure cost with respect to landfills, asbestos remediation and other ongoing environmental monitoring. The following table represents the activity associated with our asset retirement obligations.

	For The Years Ended December 31,

Net Periodic Cost

Service cost is the actuarial present value of benefits attributed by the plans’ benefit formula to services rendered by employees during the year. Interest cost represents the increase in the projected benefit obligation, which is a discounted amount, due to the passage of time. The expected return on plan assets reflects the computed amount of current-year earnings from the investment of plan assets using an estimated long-term rate of return.
