PART I

Item 1. Business

Introduction

Cliffs is the largest flat-rolled steel producer in North America. Founded in 1847 as a mine operator, we are also the largest supplier of iron ore pellets in North America. In 2020, we acquired two major steelmakers, AK Steel and ArcelorMittal USA, vertically integrating our legacy iron ore business with quality-focused steel production and emphasis on the automotive end market. Our fully integrated portfolio includes custom-made pellets and HBI; flat-rolled carbon steel, stainless, electrical, plate, tinplate and long steel products; as well as carbon and stainless steel tubing, hot and cold stamping and tooling. Headquartered in Cleveland, Ohio, we employ approximately 25,000 people across our mining, steel and downstream manufacturing operations in the United States and Canada.

On March 13, 2020, we completed the acquisition of AK Steel, a leading producer of flat-rolled carbon, stainless and electrical steel products. These operations consist primarily of seven steelmaking and finishing plants, two cokemaking operations, three tube manufacturing plants and ten tooling and stamping operations. The Tubular Components and Precision Partners businesses provide customer solutions with carbon and stainless steel tubing products, die design and tooling, and hot- and cold-stamped components.

On December 9, 2020, we completed the acquisition of ArcelorMittal USA. These operations include six steelmaking facilities, eight finishing facilities, two iron ore mining and pelletizing operations, one coal mining complex and three cokemaking operations. These assets build upon our existing high-end steelmaking and raw material capabilities, and also open up new markets to us. The combination provides us additional scale and technical capabilities necessary in a competitive and increasingly quality-focused marketplace.

Competitive Strengths

As the largest flat-rolled steel producer in North America, we benefit from having the size and scale necessary in a competitive, capital intensive business. Our sizeable operating footprint provides us with the operational leverage, flexibility and cost performance to achieve competitive margins throughout the business cycle. We also have a unique vertically integrated profile, which begins at the mining stage and goes all the way through the manufacturing of steel products, including stamping, tooling and tubing. This positioning gives us both lower and more predictable costs throughout the supply chain and more control over both our manufacturing inputs and our end product destination.

Our legacy business of producing iron ore pellets, our primary steelmaking raw material input, is another competitive advantage. Mini-mills (producers using EAFs) comprise about 70% of steel production in the U.S. Their primary iron input is scrap metal, which has unpredictable and often volatile pricing. By controlling our iron ore pellet supply, our primary steelmaking raw material feedstock can be secured at a stable and predictable cost, and not subject to factors outside of our control.

We are also the largest supplier of automotive-grade steel in the U.S. Compared to other steel end markets, automotive steel is generally higher quality and more operationally and technologically intensive to produce. As such, it often generates higher through-the-cycle margins, making it a desirable end market for the steel industry. With our continued technological innovation, as well as leading delivery performance, we expect to remain the leader in supplying this industry.

We offer the most comprehensive flat-rolled steel product selection in the industry, along with several complementary products and services. A sampling of this offering includes AHSS, hot-dipped galvanized, aluminized, galvalume, electrogalvanized, galvanneal, HRC, cold-rolled coil, plate, tinplate, GOES, NOES, stainless steels, tool & die, stamped components, rail and slabs. Across the quality spectrum and the supply chain, our customers can frequently find the solutions they need from our product selection.

We are the first and the only supplier of HBI in the Great Lakes region. Construction of our Toledo, Ohio, direct reduction plant was completed in the fourth quarter of 2020. From this modern plant, we offer a high-quality scrap and pig iron alternative to the several EAFs in the region. Previously, ore-based metallics that compete with our HBI had to be imported from locations like Russia, Ukraine and Brazil. With growing EAF capacity in the U.S. and

increasing tightness in the scrap market, we expect our Toledo direct reduction plant to generate healthy margins for us going forward.

Strategy

Optimizing Our Fully-Integrated Steelmaking Footprint

We have transformed into a fully-integrated steel enterprise with the size and scale to achieve improved through-the-cycle margins and are the largest flat-rolled steel producer in North America.

Now that the AM USA Transaction is completed, our focus is on the integration of these facilities within our footprint. These assets build upon our existing high-end steelmaking and raw material capabilities, and also open up new markets to us. The combination provides us the additional scale and technical capabilities necessary in a competitive and increasingly quality-focused marketplace. We have ample opportunities to implement improvements in logistics, procurement, utilization and quality.

We expect the AM USA Transaction to improve our production capabilities, flexibility, and cost performance. We have identified approximately $150 million of potential cost synergies through asset optimization, economies of scale, and duplicative overhead savings. The AM USA Transaction also enhances optionality for future production of merchant pig iron to complement our HBI offering in the metallics space.

Maximizing Our Commercial Strengths

With the Acquisitions completed, we now have enhanced our offering to a full suite of flat steel products encompassing all steps of the steel manufacturing process. We have increased our industry-leading market share in the automotive sector, where our portfolio of high-end products will deliver a broad range of differentiated solutions for this highly sought after customer base.

We believe we have the broadest flat steel product offering in North America, and can meet customer needs from a variety of end markets and quality specifications. We have several finishing and downstream facilities with advanced technological capabilities. We also pride ourselves on our excellent delivery performance, which provides us opportunities to augment our relationships with current customers given our reputation as a reliable supplier.

We are also proponents of the “value over volume” approach in terms of steel supply. We take our leadership role in the industry very seriously and intend to manage our steel output in a responsible manner.

Expanding to New Markets

Our Toledo direct reduction plant allows us to offer another unique, high-quality product to discerning raw material buyers. EAF steelmakers primarily use scrap for their iron feedstock, and our HBI offers a sophisticated alternative with less impurities, allowing other steelmakers to increase the quality of their respective end-steel products and reduce reliance on imported metallics.

The completed Acquisitions provide other potential outlets for HBI, as it can also be used in our integrated steel operations to increase productivity and help to reduce carbon footprint, allowing for more cost efficient and environmentally friendly steelmaking.

We are also seeking to expand our customer base with the rapidly growing and desirable electric vehicle market. At this time, we believe the North American automotive industry is approaching a monumental inflection point, with the adoption of electrical motors in passenger vehicles. As this market grows, it will require more advanced steel applications to meet the needs of electric vehicle producers and consumers. With our unique technical capabilities, we believe we are positioned better than any other North American steelmaker to supply the steel and parts necessary to fill these needs.

Improving Financial Flexibility

Given the cyclicality of our business, it is important to us to be in the financial position to easily withstand any negative demand or pricing pressure we may encounter. As such, our top priority for the allocation of our free cash flow is to improve our balance sheet via the reduction of long-term debt. During the COVID-19 pandemic, we were able to issue secured debt to provide insurance capital through the uncertain industry conditions that the pandemic caused. Now that business conditions have improved and we expect to generate healthy free cash flow during 2021, we have the ability to lower our long-term debt balance.

5

Our stated initial target will be to reduce total debt to less than three times our annual Adjusted EBITDA. We will continue to review the composition of our debt, as we are interested in both extending our maturity profile and increasing our ratio of unsecured debt to secured debt, which we demonstrated by executing a series of favorable debt and equity capital markets transactions during February 2021, as described under Part II – Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. These actions will better prepare us to navigate more easily through potentially volatile industry conditions in the future.

Enhance our Environmental Sustainability

As the Company transforms, our commitment to operating our business in a more environmentally responsible manner remains constant. One of the most important issues impacting our industry, our stakeholders and our planet is climate change. As a result, we are continuing Cliffs’ proactive approach by announcing our plan to reduce GHG emissions 25% from 2017 levels by 2030. This goal represents combined Scope 1 (direct) and Scope 2 (indirect) GHG emission reductions across all of our operations.

Prior to setting this goal with our newly acquired steel assets, we exceeded our previous 26% GHG reduction target at our legacy facilities six years ahead of our 2025 goal. In 2019, we reduced our combined Scope 1 and Scope 2 GHG emissions by 42% on a mass basis from 2005 baseline levels. Our goal is to further reduce those emissions in coming years.

Additionally, many of our steel assets have improved plant and energy efficiency through participation in programs like the U.S. Department of Energy’s Better Plants program and the EPA’s Energy Star program. With our longstanding focus on plant and energy efficiency, we aim to build on our previous successes across our newly integrated enterprise.

Our GHG reduction commitment is based on executing the following five strategic priorities:

•Developing domestically sourced, high quality iron ore feedstock and utilizing natural gas in the production of HBI;

•Implementing energy efficiency and clean energy projects;

•Investing in the development of carbon capture technology;

•Enhancing our GHG emissions transparency and sustainability focus; and

•Supporting public policies that facilitate GHG reduction in the domestic steel industry.

Business Operations

We are vertically integrated from the mining of iron ore and coal; to production of metallics and coke; through iron making, steelmaking, rolling and finishing; and to downstream tubular components, stamping and tooling. We have the unique advantage as a steel producer of being fully or partially self-sufficient with our production of raw materials for steel manufacturing, which includes iron ore pellets, HBI and coking coal. As we expand our presence, we believe such vertical integration represents a sustainable business model that is in the best interest of all stakeholders and the surest way to secure a long-term competitive advantage.

We strive to operate responsibly and produce more environmentally friendly iron ore pellets that enable production of clean steel, which is also the most recycled material on the planet. Additionally, our investment in the direct reduction plant in Toledo, Ohio, also helps to support environmental stewardship, as the production of HBI is more environmentally friendly than its substitute, foreign pig iron. From a focus on key environmental processes, such as steel recycling and water reuse, to corporate and social responsibility, sustainability is central to our values and operations.

We have updated our segment structure to coincide with our new business model and are organized into four operating segments based on differentiated products, Steelmaking, Tubular, Tooling and Stamping, and European Operations. Through the third quarter ended September 30, 2020, we had operated through two reportable segments – the Steel and Manufacturing segment and the Mining and Pelletizing segment. However, given the recent transformation of the business, beginning with our financial statements as of and for the year ended December 31, 2020, we primarily operate through one reportable segment – the Steelmaking segment.

Customers and Markets

We primarily sell our products to customers in four broad market categories: automotive; infrastructure and manufacturing, which includes electrical power; distributors and converters; and steel producers, which consume iron ore and metallics. The following table presents the percentage of our net sales to each of these markets during the year:

Market	2020
Automotive	45	%
Infrastructure and manufacturing	15	%
Distributors and converters	13	%
Steel producers	27	%

Certain of our flat-rolled steel shipments are sold under fixed base price contracts. These contracts are typically one year in duration and expire at various times throughout the year. Some of these contracts have a surcharge mechanism that passes through certain changes in input costs. A certain portion of our flat-rolled steel shipments are sold based on the spot market at prevailing market prices or under contracts that involve variable pricing that is tied to an independently published steel index.

We sell our steel products principally to customers in North America. For the vast majority of international sales, we are not the importer of record and do not bear the responsibility for paying any applicable tariffs.

Automotive Market

The automotive industry is our largest market, and we aim to address the principal needs of major automotive manufacturers and their suppliers. We specialize in manufacturing difficult-to-produce, high-quality steel products, combined with demanding delivery performance, customer technical support and collaborative relationships, to develop breakthrough steel solutions that help our customers meet their product requirements. In addition, many of our competitors do not have the capability to supply the full portfolio of products that we make for our automotive customers, such as steel for exposed automotive applications, the most sophisticated grades of AHSS and value-added stainless steel products. The exacting requirements for servicing the automotive market generally allows for higher selling prices for products sold to that market than for the commodity types of carbon and stainless steels sold to other markets.

In light of the automotive market’s importance to us, North American light vehicle production has a significant impact on our total sales and shipments. North American light vehicle production for 2020 declined 20% to approximately 13 million units from the prior year due to impacts of the COVID-19 pandemic, which forced businesses to begin to shut down at the end of March 2020 until they slowly re-started near the end of the second quarter. During the third quarter of 2020, auto makers saw the pent-up demand bring sales back to more normal levels as buyers and dealers adapted to new procedures and virtual shopping. Fourth quarter 2020 sales were more in line with expected sales for the time of year, but did not quite return to pre-COVID-19 levels. Currently, we are expecting North American light vehicle production in 2021 to significantly increase and return to near 2019 levels, which to an extent depends on continued demand, the level of fiscal stimulus provided under the new Biden Administration, timing of COVID-19 vaccination distribution and how quickly the economy recovers.

Furthermore, during 2020, consumer demand for sport utility vehicles, trucks, crossovers and larger vehicles continued to increase while demand for smaller sedans and compact cars declined. We benefit from intentionally targeting larger vehicle platforms to take advantage of consumer preferences, and we have focused on and have been successful in getting sourced on numerous sport utility vehicles, truck, crossover and larger vehicle platforms. As a result, a significant portion of the carbon automotive steel that we sell is used to produce these popular larger vehicles. In addition to benefiting from our exposure to consumers’ strong demand for larger vehicles, these vehicles also typically contain a higher volume of steel than smaller sedans and compact cars, providing us the opportunity to sell a greater proportion of our steel products to our automotive customers.

Automotive manufacturers are under pressure to achieve heightened federally mandated fuel economy standards (the Corporate Average Fuel Economy, or “CAFE,” standards). The CAFE standards generally require automobile manufacturers to meet an average fuel economy goal across the fleet of vehicles they produce with certain milestone dates. As a result, our automotive customers continue to explore various avenues for achieving the standards, including light weighting components and developing more fuel-efficient engines. Light weighting efforts include the use of alternatives to traditional carbon steels, such as AHSS and other materials. While this could reduce the aggregate volume of steel consumed by the automotive industry, we expect that demand will increase for current

and next-generation AHSS and that our AHSS and other innovative steels will command higher margins. We are collaborating with our automotive customers and their suppliers to develop innovative solutions using our developments in light weighting, efficiency, and material strength and formability across our extensive product portfolio, in combination with our automotive stamping and tube-making capabilities. We are also working with our customers to develop steels with greater heat resistance for exhaust systems that support new, fuel-efficient engines that run at higher temperatures.

Automotive manufacturers have also been increasing their development of H/EVs and battery electric vehicles in order to meet the CAFE standards and growing customer adoption of H/EVs. Many motors used in H/EVs being sold in the U.S. today are imported from foreign suppliers, but more local sourcing and manufacturing of motors is expected to occur in the future. As the only North American producer of high-efficiency NOES, which is a critical component of H/EV motors, we are positioned to potentially benefit from the growth of H/EVs going forward. We believe our strong foundation in electrical steels and long-standing relationships with automotive manufacturers and their suppliers will provide us with an advantage in this market as it continues to grow and mature. Likewise, the growing customer adoption of H/EVs may also increase demand for improvements in the electric grid to support higher demand for more extensive battery charging, which our GOES could support.

Infrastructure and Manufacturing Market

We sell a variety of our steel products, including plate, carbon, stainless, electrical, tinplate and rail, to the infrastructure and manufacturing market. This market includes sales to manufacturers of heating, ventilation and air conditioning equipment, appliances, power transmission and distribution transformers, storage tanks, ships and railcars, wind towers, machinery parts, heavy equipment, military armor, food preservation, and railway lines. Domestic construction activity and the replacement of aging infrastructure directly affects sales of steel to this market. During 2020, there were nearly 1.4 million new housing starts in the U.S., an increase of approximately 6% from 2019, and home sales reached nearly 6 million, the highest annual mark since 2006, with the supply of existing homes having reached all-time lows. The recent strength in home sales has been due to lower mortgage rates and remote work flexibility and is expected to continue through 2021.

Distributors and Converters Market

Virtually all of the grades of steel we produce are sold to the steel distributors and converters market. This market generally represents downstream steel service centers, who source various types of steel from us and fabricate it according to their customers' needs. Our steel is typically sold to this market on a spot basis or under short-term contracts linked to steel pricing indices. Demand and pricing for this market can be highly dependent on a variety of factors outside our control, including global and domestic commodity steel production capacity, the relative health of countries’ economies and whether they are consuming or exporting excess steel capacity, the provisions of international trade agreements and fluctuations in international currencies and, therefore, are subject to market changes in steel prices.

The price for domestic HRC, which is an important attribute in the profitability of this end market, averaged $588 per net ton for the year ended December 31, 2020, 2% lower than the prior year. The price of HRC was negatively impacted by lower demand related to the COVID-19 pandemic, and hit a low point of $438 per net ton on April 30, 2020. However, as the industry recovered and supply-demand dynamics improved, the price rebounded dramatically, rising to a peak of $1,030 per net ton by December 31, 2020 and reaching all time-highs early in 2021. The improved pricing environment should bolster profitability for this end market during 2021.

Steel Producers Market

The steel producers market represents third-party sales to other steel producers, including those who operate blast furnaces and EAFs. It includes sales of raw materials and semi-finished and finished goods, including iron ore pellets, coal, coke, HBI and steel products.

The merchant portion of our iron ore pellet production is sold pursuant to long-term supply agreements and through spot contracts. Certain of our supply agreements contain a base price that is adjusted periodically as specified by the contracts, using one or more adjustment factors. Factors that could result in price adjustments under our contracts include changes in the Platts 62% price, published Platts international indexed freight rates and changes in specified PPI, including those for industrial commodities, fuel and steel.

As a result of the Acquisitions, production from our iron ore mines is now predominantly consumed by our newly acquired steelmaking operations. On a full-year basis, we would expect between 22 million and 24 million long tons of our iron ore pellets to be consumed by our steelmaking operations. During 2020, 2019 and 2018, we sold 12

9

million, 19 million and 21 million long tons of iron ore product, respectively, to third parties from our share of production from our iron ore mines.

We produce various grades of iron ore pellets, including standard, fluxed and DR-grade, for use as part of the steelmaking process. The variation in grade of iron ore pellets results from the specific chemical and metallurgical properties of the ores at each mine, the requirements of end users' steelmaking processes and whether or not fluxstone is added in the process. Although the grade or grades of pellets currently delivered to each customer are based on that customer’s preferences, which depend in part on the characteristics of the customer’s steelmaking operation, in certain cases our iron ore pellets can be used interchangeably. Standard pellets require less processing, are generally the least costly pellets to produce and are called “standard” because no ground fluxstone, such as limestone or dolomite, is added to the iron ore concentrate before turning the concentrate into pellets. In the case of fluxed pellets, fluxstone is added to the concentrate, which produces pellets that can perform at higher productivity levels in the customer’s specific blast furnace and will minimize the amount of fluxstone the customer may be required to add to the blast furnace. DR-grade pellets require additional processing to make a pellet that contains higher iron and lower silica content than a standard pellet. Unlike standard or fluxed pellets, DR-grade pellets are produced to be fed into a direct reduction facility.

Beginning in 2021, we expect to also sell HBI to third-party customers, primarily EAFs with operations in the Great Lakes region. We expect our Toledo direct reduction plant to begin shipping saleable product to third-party customers during the first quarter of 2021. The Toledo direct reduction plant has a nameplate production capacity of 1.9 million metric tons, and we expect to reach its productive capacity by the second quarter of 2021.

Applied Technology, Research and Development

We have an extensive history of being an innovator dating back more than a century. From upstream research and development, to downstream applications, we have dedicated technical and engineering resources that begin with improving customers' production and manufacturing performance to applications for their end product use.

We have been a leader in iron ore mining and processing technology through the application of new technology to the centuries-old business of mineral extraction. We have also been a pioneer in iron ore pelletizing with over 60 years of experience. We are able to produce customized, environmentally friendly pellets to meet blast furnace specifications and produce standard, fluxed and DR-grade pellets.

We now have a world-class research and development team expanding our capabilities to bring new steel products to the marketplace. Rapidly evolving and highly competitive markets for our steel products require our customers to seek new, comprehensive steel solutions, and we believe we are well positioned to deliver the most robust solutions through our broad portfolio of offerings. Collaboration across our research groups and operations generates innovative and comprehensive solutions for our customers, which we believe enhances our competitive advantage.

Creating innovative products and breakthrough solutions is a strategic priority, as we believe differentiation through producing higher value steels to meet challenging requirements enables us to maintain and enhance our margins. We conduct a broad range of research and development activities aimed at improving existing products and processes and developing new ones. Our innovation of steel has produced a highly diversified steel product portfolio. As part of our underlying strategy to focus on higher-value materials and minimize exposure to commodity products, we have invested in research and innovation totaling $15 million in 2020. Our ongoing efforts at our state-of-the-art Research and Innovation Center in Middletown, Ohio, to enhance technical collaboration have increased the introduction of new steel solutions to the marketplace.

HBI

We are a pioneer in the development of emerging reduction technologies, a leader in the extraction of value from challenging resources and a front-runner in the implementation of safe and sustainable technology. We are also devoted to promoting environmental sustainability, evidenced with the development of our direct reduction plant in Toledo, Ohio. We expect our introduction of HBI to the Great Lakes EAF market will be notable in the evolution of the steel industry.

We completed construction of our Toledo direct reduction plant and began production in the fourth quarter of 2020. Our Toledo direct reduction plant is expected to produce 1.9 million metric tons of HBI per year, replacing a portion of the over 3 million metric tons of ore-based metallics that are imported into the Great Lakes region every year from Russia, Ukraine, Brazil and Venezuela, as well as approximately 20 million metric tons of scrap used in the Great Lakes area every year.

Carbon Steel

We focus much of our research and innovation efforts on carbon steel applications for automotive manufacturers and their suppliers. We are particularly focused on AHSS for the automotive market, and we produce virtually every AHSS grade currently used by our customers. Our AHSS grades, such as Dual Phase 590, 780, 980 and 1180, have been adopted by our customers for both stamped and roll-formed parts, and our NEXMET® 1000 and 1200 products have demonstrated enhanced strength, formability and opportunities for automotive light weighting in cold-stamped applications. We are also pursuing application of NEXMET 440EX and NEXMET 490EX in surface-critical, exposed auto body panels as an alternative to aluminum.

Third Generation Advanced High-Strength Steel

Our third generation NEXMET 1000 and NEXMET 1200 AHSS products enable our customers to achieve significant light weighting in the unexposed structural components of their vehicles. NEXMET 1200, for example, offers superior formability similar to conventional Dual Phase 600 steel, but at twice the strength level. We have expanded the application of the NEXMET technology to our tubular products and stamped components businesses. These AHSS products allow automotive engineers to design lightweight parts that meet rigorous service and safety requirements. The NEXMET family of steels helps our customers achieve vehicle weight savings for ambitious fuel efficiency standards while avoiding significant capital costs required to re-design production facilities to use alternative materials.

Both galvanized and cold-rolled NEXMET 1000 and NEXMET 1200 AHSS are progressing through product qualification with several original equipment manufacturer customers. A number of stamping and component assembly trials have been completed successfully, with more planned and underway. Because the timing of automotive design and production cycles spans several years, widespread automotive customer adoption of revolutionary new material such as NEXMET AHSS may also extend over several years. We expect that other automotive vehicle platforms will incorporate NEXMET AHSS in their designs and that NEXMET AHSS will become a strong differentiator for us going forward.

Downstream Steel Applications

Our portfolio of steel solutions includes the operations of Precision Partners, which provides advanced-engineered solutions, tool design and build, hot and cold-stamped components and complex assemblies for the automotive market. In addition to Precision Partners, our downstream operations include Tubular Components, which manufactures advanced tubular products for automotive and other applications using carbon and stainless steels. We believe that collaboration among our steelmaking operations and our downstream businesses can accelerate the adoption of our innovative steel products by automotive manufacturers and their Tier 1 suppliers.

Our research and technical experts have undertaken numerous collaborative projects that are generating robust solutions for our customers. Precision Partners’ expertise in tool design and stamping capabilities has allowed us to create prototype components using AK Steel’s innovative new materials and present customers with new potential steel solutions. This approach has and, we expect, will continue to demonstrate to customers that they can significantly lightweight automotive parts on an accelerated timeline and in a cost-effective manner by using our highly formable grades of AHSS in place of traditional material types.

In addition, our collaborative projects are enhancing our collective knowledge and experience in the stamping of new, advanced grades of steel, advanced engineered solutions, and tool design and build. For example, Precision Partners specializes in hot-stamping PHS for automotive applications. AK Steel’s experience as a leader in PHS and Precision Partners’ expertise in hot-stamping has enabled these teams to have greater insight into these high-growth areas and has accelerated product development and customer adoption of these automotive light weighting solutions. Likewise, collaboration with Tubular Components strategically advances our mission to innovate in AHSS for the automotive industry, as Tubular Components has been at the forefront of producing tubular products from third-generation AHSS. We believe the combination of Precision Partners’ stamping and advanced die-making capabilities, Tubular Component’s leading tube making capabilities and our breakthrough material introductions will enhance our ability to deliver innovative, steel solutions to our customers.

Precision Partners has recently been awarded contracts with several customers to supply complex assemblies and stamped automotive parts. In winning these contracts, Precision Partners has been able to leverage our hot-stamping tooling leadership, in addition to our innovative hot-stamping process, to capture new strategic opportunities and demonstrate that Precision Partners is one of the few businesses in North America that has the technical capabilities to produce a major complex assembly and stamping work of this nature.

Competition

We principally compete with domestic and foreign producers of flat-rolled carbon, plate, stainless, rail and electrical steel, carbon and stainless tubular products, aluminum, carbon fiber, concrete and other materials that may be used as a substitute for flat-rolled steels in manufactured products. Precision Partners and Tubular Components both compete against other niche companies in highly fragmented markets.

Price, quality, on-time delivery, customer service and product innovation are the primary competitive factors in the steel industry and vary in importance according to the product category and customer requirements. Steel producers that sell to the automotive market face competition from aluminum manufacturers (and, to a lesser extent, other materials) as automotive manufacturers attempt to develop vehicles that will enable them to satisfy more stringent, government-imposed fuel efficiency standards. To address automotive manufacturers’ light weighting needs that the aluminum industry is targeting, we and others in the steel industry are developing AHSS grades that we believe provide weight savings similar to aluminum, while being stronger, less costly, more sustainable, easier to repair and more environmentally friendly. Aluminum penetration has been primarily limited to specific automotive applications, such as outer panels and closures, rather than entire body designs. In addition, our automotive customers who continue to use steel, as opposed to aluminum and other alternative materials, are able to avoid the significant capital expenditures required to re-tool their manufacturing processes to accommodate the use of non-steel materials.

Mini-mills (producers using EAFs) comprise about 70% of steel production in the U.S. Their primary raw material is scrap metal, which has unpredictable and often volatile pricing. Due to the announced mini-mill capacity additions in the U.S. and increasing demand for scrap from China, we expect the price of scrap to remain elevated over historical averages, providing our integrated footprint a competitive advantage. Mini-mills also generally offer a narrower range of products than integrated steel mills, but the increasing use of pig iron and direct reduced iron have enabled them to modestly expand their product capabilities in recent years. However, we believe mini-mills often do not have the equipment capabilities to produce the product range that integrated facilities offer, nor do we believe they possess our depth of customer service, technical support, and research and innovation.

Domestic steel producers, including us, face significant competition from foreign producers. For many reasons, these foreign producers often are able to sell products in the U.S. at prices substantially lower than domestic producers. Depending on the country of origin, these reasons may include government subsidies; lower labor, raw material, energy and regulatory costs; less stringent environmental regulations; less stringent safety requirements; the maintenance of artificially low exchange rates against the U.S. dollar; and preferential trade practices in their home countries. Since late 2017, import levels of flat-rolled products into the United States have shown a gradual and steady decline and have recently been more reflective of historical levels before the unprecedented surge that began in 2014. We believe the decline is at least partially attributable to the implementation of certain trade restrictions on imported steel over the past five years, including both targeted trade cases and the more broad Section 232 tariffs. Modifications to these trade restrictions by government officials could directly or indirectly impact import levels in the future. Import levels are also affected to varying degrees by the relative level of steel production in China and other countries, the strength of demand for steel outside the U.S. and the relative strength or weakness of the U.S. dollar against various foreign currencies. Imports of finished steel into the U.S. accounted for approximately 18% of domestic steel market consumption in 2020.

We continue to provide significant pension and healthcare benefits to a great number of our retirees compared to certain other domestic and foreign steel producers that do not provide such benefits to any or most of their retirees, which increases our overall cost of production relative to certain other steelmakers. However, we have taken a number of actions to reduce pension and healthcare benefits costs, including negotiating progressive labor agreements that have significantly reduced total employment costs at all of our union-represented facilities, transferring all responsibility for healthcare benefits for various groups of retirees to VEBAs, offering voluntary lump-sum settlements to pension plan participants, lowering retiree benefit costs for salaried employees, and transferring pension obligations to highly rated insurance companies. These actions have not only reduced some of the risks associated with our pension fund obligations, but more importantly have reduced our risk exposure to performance of the financial markets, which are a principal driver of pension funding requirements. We continue to actively seek opportunities to reduce pension and healthcare benefits costs.

12

Environment

Our mining, steel and downstream manufacturing operations are subject to various laws and regulations governing the protection of the environment. We monitor these laws and regulations, which change over time, to assess whether the changes affect our operations. We conduct our operations in a manner that is protective of public health and the environment.

Environmental matters and their management continued to be an important focus at each of our operations throughout 2020, including operations at AK Steel (acquired in March 2020) and ArcelorMittal USA (acquired in December 2020). In the construction and operation of our facilities, substantial costs have been and will continue to be incurred to comply with regulatory requirements and avoid undue effect on the environment. In 2020, 2019, and 2018, our capital expenditures relating to environmental matters totaled approximately $34 million, $9 million, and $10 million, respectively. Our current estimate for capital expenditures for environmental improvements in 2021 is approximately $51 million for various water treatment, air quality, dust control, tailings management and other miscellaneous environmental projects. Additionally, we expect capital expenditures for environmental improvements for each of 2022 and 2023 to be generally in line with 2021's estimated spending.

Regulatory Developments

Various governmental bodies continually promulgate new or amended laws and regulations that affect us, our customers, and our suppliers in many areas, including waste discharge and disposal, the classification of materials and products, air and water discharges and other environmental, health, and safety matters. Although we believe that our environmental policies and practices are sound and do not expect that the application of any current laws, regulations or permits would reasonably be expected to result in a material adverse effect on our business or financial condition, we cannot predict the collective potential adverse impact of the expanding body of laws and regulations. Moreover, because all domestic steel and mining producers operate under the same federal environmental regulations, we do not believe that we are more disadvantaged than our domestic competitors by our need to comply with these regulations. Some foreign competitors may benefit from less stringent environmental requirements in the countries where they produce, resulting in lower compliance costs for them and providing those foreign competitors with a cost advantage on their products.

Specifically, there are several notable proposed or potential rulemakings or activities that could have a material adverse impact on our facilities in the future depending on their ultimate outcome: Minnesota's potential revisions to the sulfate wild rice water quality standard; evolving water quality standards for selenium and conductivity; scope of the Clean Water Act and the definition of “Waters of the United States”; Minnesota's Mercury TMDL and associated rules governing mercury air emission reductions; Climate Change and GHG Regulation; the Regional Haze FIP Rule; and the regulation of discharges to groundwater.

Minnesota’s Sulfate Wild Rice Water Quality Standard

The Minnesota Governor established a Wild Rice Task Force by Executive Order in May 2018 that provided recommendations to the Governor’s Office on wild rice restoration and regulation. The existing water quality standard for wild rice has not been applied to any of our discharge permits or enforced in decades, and it may be unenforceable because of legislation and because the water bodies to which the existing standard applies have never been identified specifically in rule, nor are there criteria for identifying them. The MPCA is complying with the legislation that prohibits enforcement of the water quality standard until the obsolete standard is updated based on modern science. For these reasons, the impact of the proposed wild rice water quality standard to our Minnesota iron ore mining and pelletizing operations is not estimable at this time, but it could have an adverse material impact if we are required to significantly reduce sulfate in our discharges.

Selenium Discharge Regulation

In Michigan, the Empire and Tilden mines have implemented compliance plans to manage selenium according to the permit conditions. The remaining infrastructure needed for management of selenium in stormwater will likely be completed in 2021. A water treatment system for both facilities is anticipated sometime before 2028. As of December 31, 2020, included within our Empire asset retirement obligation is a discounted liability of approximately $100 million, which includes the estimated costs associated with the construction of Empire's portion of the required infrastructure and expected future operating costs of the treatment facilities. Additionally, included within our Tilden future capital plan is approximately $20 million for the construction of Tilden's portion of the required infrastructure. We are continuing to assess and develop cost effective and sustainable treatment technologies.

13

In July 2016, the EPA published new selenium fish tissue limits and lower lentic and lotic water column concentration criteria, which may someday increase the cost for treatment should EGLE adopt these new standards in lieu of the existing limits required by the Great Lakes Water Quality Initiative. Accordingly, we cannot reasonably estimate the timing or long-term impact of the water quality criteria to our business.

Mercury TMDL and Minnesota Taconite Mercury Reduction Strategy

In September 2014, Minnesota promulgated the Mercury Air Emissions Reporting and Reduction Rules mandating mercury air emissions reporting and reductions from certain sources, including taconite facilities. The rule is applicable to all of our Minnesota iron mining and pelletizing operations and required submittal of a Mercury Reduction Plan to the MPCA by the end of 2018 with plan implementation requirements becoming effective on January 1, 2025. In the Mercury Reduction Plan, facilities evaluated if available control technologies can technically achieve a 72% mercury reduction rate. If available control technologies cannot technically achieve a 72% mercury reduction rate, the facilities must propose alternative mercury reduction measures. One of the main tenets agreed upon for evaluating potential mercury reduction technologies during TMDL implementation and 2014 rule development proceedings was that the selected technology must meet the following “Adaptive Management Criteria”: the technology must be technically feasible; must be economically feasible; must not impact pellet quality; and must not cause excessive corrosion in the indurating furnaces or air pollution control equipment.

The Mercury Reduction Plans for our Minnesota facilities were submitted to the MPCA in December 2018. In 2020, the MPCA provided comments on the plans and we responded in a timely manner. There is currently no proven technology to cost effectively reduce mercury emissions from taconite furnaces to achieve the targeted 72% reduction rate, while satisfying all four Adaptive Management Criteria. The Mercury Reduction Plans that were submitted to the MPCA include documentation that describes the results of detailed engineering analysis and research testing on potential technologies to support this determination. The results of this analysis will continue to guide dialogue with the MPCA. Potential impacts to us are not estimable at this time because the revised Mercury Reduction Plans and additional technical information are currently being reviewed by the MPCA.

Climate Change and GHG Regulation

With the complexities and uncertainties associated with the U.S. and global navigation of the climate change issue as a whole, one of our potentially significant risks for the future is mandatory carbon pricing obligations. Policymakers are in the design process of carbon regulation at the state, regional, national and international levels. The current regulatory patchwork of carbon compliance schemes presents a challenge for multi-facility entities to identify their near-term risks. Amplifying the uncertainty, the dynamic forward outlook for carbon pricing obligations presents a challenge to large industrial companies to assess the long-term net impacts of carbon compliance costs on their operations. Our exposure on this issue includes both the direct and indirect financial risks associated with the regulation of GHG emissions, as well as potential physical risks associated with climate change adaptation. We are continuing to review the physical risks related to climate change. As an energy-intensive business, our GHG emissions inventory includes a broad range of emissions sources, such as iron ore furnaces and kilns, diesel mining equipment, and integrated steelmaking facilities, among others. As such, our most significant regulatory risks are: (1) the costs associated with on-site emissions levels (direct impacts), and (2) indirect costs passed through to us from electrical and fuel suppliers (indirect impacts).

Internationally, mechanisms to reduce emissions are being implemented in various countries, with differing designs and stringency, according to resources, economic structure and politics. The Paris Agreement to reduce global GHG emissions and limit global temperature increases to 2 degrees Celsius became effective in November 2016 with 196 signatory countries. On January 20, 2021, President Biden signed an executive order triggering the 30-day process of rejoining the Paris Agreement, beginning the process of a pledge to reduce U.S. GHG emissions. During the Obama Administration, the U.S. became a signatory to the Paris Agreement with a pledge to reduce its GHG emissions by 26-28% from 2005 levels by 2025. Continued attention to issues concerning climate change, the role of human activity in it and potential mitigation through regulation may have a material impact on our customer base, operations and financial results in the future.

In the U.S., future federal and/or state carbon regulation potentially presents a significantly greater impact to our operations. To date, the U.S. Congress has not legislated carbon constraints. In the absence of comprehensive federal carbon legislation, numerous state, regional and federal regulatory initiatives are under development or are becoming effective, thereby creating a disjointed approach to GHG control and potential carbon pricing impacts. We intend to remain active in the discussions related to legislative and regulatory changes at the federal and state levels.

14

Due to the potential patchwork of federal, state or regional carbon restriction schemes, our business and customer base could suffer negative financial impacts over time as a result of increased energy, environmental and other costs to comply with the limitations that would be imposed on GHG emissions. We believe our exposure can be reduced substantially by numerous factors, including currently contemplated regulatory flexibility mechanisms, such as allowance allocations, fixed process emissions exemptions, offsets and international provisions; emissions reduction opportunities, including energy efficiency, biofuels and fuel flexibility; and business opportunities associated with pursuing combined heat and power partnerships and new products, including DR-grade pellets, HBI, fluxed pellets and other efficiency-improving technologies.

Regional Haze FIP Rule

In June 2005, the EPA finalized amendments to its regional haze rules that require states to establish goals and emission reduction strategies for improving visibility in all Class I national parks and wilderness areas to natural background levels by 2064. Among the states with Class I areas are Michigan and Minnesota, in which we currently own mining operations, and Indiana, in which we own steelmaking operations. The first phase of the regional haze rule required analysis and installation of BART on eligible emission sources and incorporation of BART and associated emission limits into SIPs.

EPA disapproved Minnesota's and Michigan's BART SIPs for taconite furnaces and instead promulgated a Taconite Regional Haze FIP in February 2013. We petitioned the Eighth Circuit Court of Appeals for a review of the FIP and filed a joint motion for stay of the 2013 FIP, which was granted in June 2013. We reached a settlement agreement with EPA, which was subsequently published in the Federal Register to implement components of the settlement agreement in April 2016, with an effective date of May 12, 2016. We believe the 2016 Regional Haze FIP reflects progress toward a more technically and economically feasible regional haze implementation plan. In November 2016, the Eighth Circuit Court of Appeals terminated the June 2013 stay and extended the deadlines in the original 2013 FIP. Cost estimates associated with implementation of the 2013 and 2016 FIPs are reflected in our five-year capital plan.

Due to inconsistencies in language describing the procedures for calculating NOx emission limits between the settlement agreement and the 2016 FIP final rule, we jointly filed a Petition for Reconsideration and Petition for Judicial Review in June 2016. We have been working toward a settlement agreement with EPA to resolve the outstanding issue with the emission limit calculation method and anticipate resolution of the issue in 2021. The outcome of this proceeding is not expected to have a material adverse impact on us.

In 2020, the states began a second decadal review, which examined if additional technological controls are warranted for certain sources. The states are required to submit their updated Regional Haze SIPs by July 2021. At this time, we do not expect any state will require additional emission control requirements on our operations. We will review and comment on SIPs as necessary in the states in which we operate.

Conductivity

Conductivity, the measurement of water’s ability to conduct electricity, is a surrogate parameter that generally increases as the amount of dissolved minerals in water increases. In December 2016, EPA issued a notice soliciting public comments on its draft guidance, Field-Based Methods for Developing Aquatic Life Criteria for Specific Conductivity. In April 2017, comments were submitted by our trade associations providing objective evidence indicating the draft methodology was scientifically flawed and unfit for promulgation. EPA confirmed in October 2019 that the 2016 draft guidance was rescinded in accordance with an August 2019 EPA memorandum regarding draft guidance documents and further expressed that EPA must update the science and subject future recommended methods or criteria for conductivity to peer review and public comment. Although the adoption of the previously proposed methodology is unlikely in the states, the Fond du Lac Band in Minnesota adopted certain conductivity criteria in 2020. We are assessing the impact of those criteria on our Minnesota iron ore mining and pelletizing operations and evaluating methods to challenge the criteria as a whole or on a site-by-site basis.

Definition of “Waters of the United States” Under the Clean Water Act

The EPA and Army Corps of Engineers published a final rule in October 2019 repealing the 2015 rule that was to become effective on December 23, 2019. On April 21, 2020, the EPA and the Department of the Army published the Navigable Waters Protection Rule in the Federal Register to finalize a revised definition of “waters of the United States” under the Clean Water Act. For the first time, the agencies have streamlined the definition so that it includes four simple categories of jurisdictional waters, provides clear exclusions for many water features that traditionally have not been regulated, and defines terms in the regulatory text that have never been defined before. The rule is on

15

appeal in various jurisdictions. The rule is not expected to have a material adverse effect on us, but we will continue to assess the potential impacts to our operations.

Regulation of Discharges to Groundwater

In general, states traditionally have regulated discharges of pollutants to groundwater through various programs such as wellhead protection programs and regulations related to remediation. In April 2020, the United States Supreme Court held in County of Maui v. Hawaiʻi Wildlife Fund that EPA (and delegated states) have jurisdiction under the NPDES program if the discharge to groundwater is the “functional equivalent” of a discharge to waters of the United States. Until now, the NPDES program has only regulated direct discharges to waters of the United States from point sources. EPA subsequently issued a guidance document on what the term “functional equivalent” means. Although we do not anticipate that broadening EPA jurisdiction over groundwater discharges will materially adversely affect our operations, the impact to our operations is not reasonably estimable at this time.

Raw Materials and Energy

Our steelmaking operations require iron ore, coke, coal, ferrous and carbon and stainless scrap, chrome, nickel and zinc as primary raw materials. We also consume natural gas, electricity, industrial gases and diesel fuel at our steelmaking and mining operations. As a vertically integrated steel company, we are able to internally supply a majority of our raw materials needed for our steelmaking operations. We also attempt to reduce the risk of future supply shortages and price volatility in other ways. If multi-year contracts are available in the marketplace for those raw materials that we cannot supply internally, we may use these contracts to secure sufficient supply to satisfy our key raw material needs. When multi-year contracts are not available, or are not available on acceptable terms, we purchase the remainder of our raw materials needs under annual contracts or conduct spot purchases. We also regularly evaluate alternative sources and substitute materials. Additionally, we may hedge portions of our energy and raw materials purchases to reduce volatility and risk. We believe that we have secured, or will be able to secure, adequate supply to fulfill our raw materials and energy requirements for 2021.

The raw materials needed to produce a ton of steel will fluctuate based upon the specifications of the final steel products, the quality of raw materials and, to a lesser extent, differences among steel production equipment. For example, generally, in our integrated steelmaking facilities, we consume approximately 1.4 net tons of coal to produce one net ton of coke. The process to produce one ton of raw steel generally requires approximately 1.4 net tons of iron ore pellets, 0.4 net tons of coke and 0.3 net tons of steel scrap. At normal operating levels, we also consume approximately 6 MMBtu’s of natural gas per net ton produced. Additionally, on average, our EAF's require 1.1 net tons of ferrous or stainless scrap to produce one net ton of high quality steel. We consume approximately 420 kilowatt-hours of electricity per net ton of steel produced. While these estimated consumption amounts are presented to give a general sense of raw material and energy consumption used in our steel production, substantial variations may occur.

Our investment into HBI production provides us access, when needed, to clean iron units in order to make advanced steel and stainless products. This access to our own production provides us flexibility and allows us to avoid the risks and carbon footprints of imported iron substitutes. Iron substitutes imported into the U.S. are traditionally sourced from regions of the world that have historically experienced greater political turmoil and have lower pollution standards than the U.S. Our investment demonstrates our raw material and company strategy in responsibly managing the risks of pricing, availability and overall carbon footprint of our critical inputs.

We typically purchase ferrous and stainless steel scrap, natural gas, a substantial portion of our electricity and most other raw materials at prevailing market prices, which may fluctuate with market supply and demand.

Iron Ore

We own or co-own five active iron ore mines in Minnesota and Michigan. Based on our ownership in these mines, our share of annual rated iron ore production capacity is approximately 28.0 million long tons, which supplies all of the iron ore needed for our steelmaking operations. Refer to Part I - Item 2. Properties for additional information.

Coke and Coal

We own five cokemaking facilities, including two coke batteries located within our steelmaking facilities. These facilities currently provide over half of the coke requirements for our steelmaking operations and have an annual rated capacity of approximately 3.9 million tons. Additionally, we have coke supply agreements with suppliers that provide our remaining requirements. Our purchases of coke are made under annual or multi-year agreements

16

with periodic price adjustments. We typically purchase most of our metallurgical coal under annual fixed-price agreements. We have annual rated metallurgical coal production capacity of 2.3 million net tons from our Princeton mine, which supplies a portion of our metallurgical coal needs. We believe there are adequate external supplies of coke and coal available at competitive market prices to meet our needs. Refer to Part I - Item 2. Properties for additional information.

Steel Scrap and Other Materials

Generally, approximately 43% of our steel scrap requirements are generated internally through normal operations. We believe that supplies of steel scrap, chrome, nickel and zinc adequate to meet the needs of our steelmaking operations are readily available from outside sources at competitive market prices.

Energy

We consume a large amount of natural gas, electricity, industrial gases and diesel fuel, which are significant costs to our operations. The majority of our energy requirements are purchased from outside sources. Access to long-term, low cost sources of energy in various forms is critically important to our operations.

Natural gas is procured for our operations utilizing a combination of long-term, annual, quarterly, monthly and spot contracts from various suppliers at market-based pricing. We believe access to low-cost and reliable sources of natural gas is available to meet our operations’ requirements.

We purchase electricity for all of our operations in either regulated or deregulated markets. Due to the distinct nature of these markets, we procure electricity through either long-term or annual contracts. Some operations also use self-generated coke oven gas and/or blast furnace gas to produce electricity, which reduces our need to purchase electricity from external sources. We also closely monitor developments at the state and federal levels that could impact electricity availability or cost and incorporate such changes into our electricity supply strategy in order to maintain reliable, low-cost supply. We believe there is an adequate supply of competitively priced electricity to fulfill our requirements.

We purchase industrial gases under long-term contracts with various suppliers. We believe we have access to adequate supplies of industrial gases to meet our needs.

We predominantly purchase diesel fuel for our mining operations under long-term contracts with various suppliers. We believe we have access to adequate supplies of diesel fuel to meet our needs.

Human Capital

As of December 31, 2020, we employed approximately 25,000 people. Approximately 24,000 were employed in the U.S., with the remainder employed in Ontario, Canada. Approximately 24,000 employees were employed at production facilities, with the balance employed in corporate support roles. The vast majority of our approximately 20,000 hourly employees were subject to collective bargaining agreements (approximately 18,500) with various labor unions. Overall, we have good relations with our workforce and the labor unions that represent our hourly employees.

We believe that our future success largely depends upon our continued ability to attract and retain a highly skilled workforce. We provide our employees with competitive salaries, incentive-based bonus programs that provide above-market compensation opportunities when the Company performs well, development programs that enable continued learning and growth, and a robust benefit package that promotes well-being across all aspects of their lives, including health care, retirement planning and paid time off. In addition to these programs, we have used targeted, equity-based grants with vesting conditions to facilitate retention of key personnel. These tools have enabled us to increase the retention of key personnel, including our corporate and site leadership teams and critical technical talent.

The success of our business is fundamentally connected to the well-being of our people. Accordingly, we are committed to the health, safety and wellness of our employees. We provide our employees and their families with access to a variety of innovative, flexible and convenient health and wellness programs, including benefits that provide protection and security so they can have peace of mind concerning events that may require time away from work or that impact their financial well-being; that support their physical and mental health by providing tools and resources to help them improve or maintain their health and encourage engagement in healthy behaviors; and that offer choice where possible so they can customize their benefits to meet their needs and the needs of their families. In response to the COVID-19 pandemic, we implemented significant changes that we determined were in the best interest of our employees, as well as the communities in which we operate, and which comply with government regulations. This includes having all employees who could perform their work remotely work from home, while implementing numerous safety measures for employees continuing critical on-site work at our operations.

Safety

Safe production is our primary core value as we continue toward achieving a zero injury culture at our facilities. We constantly monitor our safety performance and make continuous improvements to affect change. Best practices and incident learnings are shared globally to ensure each facility can administer the most effective policies and procedures for enhanced workplace safety. Progress toward achieving our objectives is accomplished through a focus on proactive sustainability initiatives, and results are measured against established industry and company benchmarks, including our company-wide Total Reportable Incident Rate. During 2020, our Total Reportable Incident Rate (including contractors) was 0.92 per 200,000 hours worked.

Item 1A. Risk Factors

An investment in our common shares or other securities is subject to risks inherent in our businesses and the industries in which we operate. Described below are certain risks and uncertainties, the occurrences of which could have a material adverse effect on us. The risks and uncertainties described below include known material risks that we face currently, but our material risks are constantly evolving and the below descriptions may not include future risks that are not presently known, that are not currently believed to be material or that are common to all businesses. Although we have extensive risk management policies, practices and procedures in place that are aimed to mitigate these risks, the occurrence of these uncertainties may nevertheless impair our business operations and adversely affect the actual outcome of matters as to which forward-looking statements are made. This report is qualified in its entirety by these risk factors. Before making an investment decision, investors should consider carefully all of the risks described below together with the other information included in this report and the other reports we file with the SEC.

Management has identified several categories of material risk that we are subject to, including: (I) economic and market, (II) regulatory, (III) financial, (IV) operational, (V) development and sustainability and (VI) human capital. Although the risks are organized by these headings, and each risk is discussed separately, many are interrelated.

I. ECONOMIC AND MARKET RISKS

The ongoing COVID-19 pandemic has had, and is expected to continue to have, an adverse impact on our businesses.

The ongoing COVID-19 pandemic is continuing to impact countries, communities, supply chains and markets. Responses by individuals, governments and businesses to the COVID-19 pandemic and efforts to reduce its spread, including quarantines, travel restrictions, business closures, and mandatory stay-at-home or work-from-home orders, have led to significant disruptions to overall business and economic activity. While vaccines are now being manufactured and distributed, it is currently unknown when or whether the economy will return to pre-pandemic levels of consumer and business activity.

During 2020, the COVID-19 pandemic adversely affected our businesses by temporarily curtailing certain of our end markets. In particular, the automotive industry, which we rely on directly and indirectly for a significant amount of our sales, was severely disrupted during the first half of 2020. The slowdown in the automotive industry led, in turn, to disruptions to our operations. For example, although our steel and mining operations are considered “essential” by the states in which we operate, certain of our mining and production facilities were idled for various periods during 2020 in response to the decrease in customer demand. While we were able to resume operations at many of these facilities later in 2020, we cannot predict whether any other production facilities or mines will experience disruptions in the future as a result of adverse impacts of the COVID-19 pandemic.

In addition, the COVID-19 pandemic has heightened the risk that a significant portion of our workforce and on-site contractors will suffer illness or otherwise be unable to perform their ordinary work functions. While we instituted remote work policies where practical across our footprint, the safe and responsible operation of our production facilities often requires that workers be on-site. Accordingly, during 2020, we experienced direct and indirect workforce impacts from COVID-19 at many of our operations. We also may need to reduce our workforce as a result of declines in our business caused by the COVID-19 pandemic, and there can be no assurance that we will be able to rehire our workforce once our business has recovered. We may also experience supply chain disruptions or operational issues with our vendors, as our suppliers and contractors face similar challenges related to the COVID-19 pandemic.

Because the impact of the COVID-19 pandemic continues to evolve, we cannot predict the full extent to which our businesses, results of operations, financial condition or liquidity will ultimately be impacted. To the extent the COVID-19 pandemic adversely affects our businesses, it may also have the effect of exacerbating many of the other risks described in this ‘‘Risk Factors’’ section, any of which could have a material adverse effect on us.

The volatility of commodity prices, including steel and iron ore, affects our ability to generate revenue, maintain stable cash flows and fund our operations, including growth and expansion projects.

Our profitability is dependent upon the prices of the steel and iron ore products that we sell to our customers and the prices of the products our customers sell. As an integrated producer of steel and iron ore, we experience direct impacts of steel price fluctuations through customer sales, as well as direct and indirect impacts of iron ore price fluctuations through third-party sales and the impacts that fluctuations in iron ore prices have on steel prices. The prices of steel and iron ore have fluctuated significantly in the past and are affected by factors beyond our control, including: international demand for raw materials used in steel production; rates of global economic growth, especially

20

construction and infrastructure activity that requires significant amounts of steel; changes in the levels of economic activity in the U.S., China, India, Europe and other industrialized or developing economies; changes in China’s emissions policies and environmental compliance enforcement practices; changes in the production capacity, production rate and inventory levels of other steel producers and iron ore suppliers; changes in trade laws; volumes of unfairly traded imports; imposition or termination of duties, tariffs, import and export controls and other trade barriers impacting the steel and iron ore markets; weather-related disruptions, infectious disease outbreaks, such as the COVID-19 pandemic, or natural disasters that may impact the global supply of steel or iron ore; and the proximity, capacity and cost of infrastructure and transportation.

Our earnings, therefore, may fluctuate with the prices of the products we sell and of the products our customers sell. To the extent that the prices of steel and iron ore, including the hot-rolled coil steel price, coated and other specialty steel prices, the Platts 62% Price, pellet premiums and Platts international indexed freight rates, significantly decline for an extended period of time, whether due to the COVID-19 pandemic or otherwise, we may have to further revise our operating plans, including curtailing production, reducing operating costs and capital expenditures, and discontinuing certain exploration and development programs. We also may have to take impairments on our goodwill, intangible assets, long-lived assets and/or inventory. Sustained lower prices also could cause us to further reduce existing mineral reserves if certain reserves no longer can be economically mined or processed at prevailing prices. We may be unable to decrease our costs in an amount sufficient to offset reductions in revenues and may incur losses. These events could have a material adverse effect on us.

We sell a significant portion of our steel products to the automotive market and fluctuations or changes in the automotive market could adversely affect our business operations and financial performance.

For the full-year 2020, approximately 40% of AK Steel’s and ArcelorMittal USA's combined sales were to the automotive market. Beyond these direct sales to the automotive industry, we make additional sales to distributors and converters, which may ultimately resell some of that volume to the automotive market. In addition to the size of our exposure to the automotive industry, we face risks arising from our relative concentration of sales to certain specific automotive manufacturers, including several significant customers that idled certain automotive production facilities in 2020 in response to the COVID-19 pandemic. In addition, automotive production and sales are cyclical and sensitive to general economic conditions and other factors, including interest rates, consumer credit, and consumer spending and preferences, as well as the current COVID-19 pandemic. If automotive production and sales decline, our sales and shipments to the automotive market are likely to decline in a corresponding manner. Adverse impacts that we may sustain as a result include, without limitation, lower margins because of the need to sell our steel to less profitable customers and markets, higher fixed costs from lower steel production if we are unable to sell the same amount of steel to other customers and markets, and lower sales, shipments, pricing and margins generally as our competitors face similar challenges and compete vigorously in other markets that we serve. These adverse impacts would negatively affect our sales, financial results and cash flows. Additionally, the trend toward light weighting in the automotive industry, which requires lighter gauges of steel at higher strengths, could result in lower steel volumes required by that industry over time.

Moreover, despite our newly acquired position as the largest flat-rolled steel producer in North America, competition for automotive business has intensified in recent years, as steel producers and companies producing alternative materials have focused their efforts on capturing and/or expanding their market share of automotive business because of less favorable conditions in other markets for steel and other metals, including commodity products and steel for use in the oil and gas markets. As a result, the potential exists that we may lose market share to existing or new entrants or that automotive manufacturers will take advantage of the intense competition among potential suppliers during annual contract renewal negotiations to pressure our pricing and margins in order to maintain or expand our market share with them, which could negatively affect our sales, financial results and cash flows.

Global steelmaking overcapacity, steel imports and oversupply of iron ore could lead to lower or more volatile global steel and iron ore prices, impacting our profitability.

Significant global steel capacity and new or expanded production capacity in North America in recent years has caused and continues to cause capacity to exceed demand globally, as well as in our primary markets in North America. Although certain of our U.S. competitors temporarily shut down production capacity during the COVID-19 pandemic, a restart of previously idled capacity and the development of new capacity by our U.S. competitors has occurred in recent months and may occur in the future in connection with any economic recovery following the COVID-19 pandemic. In addition, foreign competitors have substantially increased their steel production capacity in the last few years and in some instances appear to have targeted the U.S. market for imports. Also, some foreign economies, such as China, have slowed relative to recent historical norms, resulting in an increased volume of steel

21

products that cannot be consumed by industries in those foreign steel producers’ own countries. The risk of even greater levels of imports may continue, depending upon foreign market and economic conditions, changes in trade agreements and treaties, laws, regulations or government policies affecting trade, the value of the U.S. dollar relative to other currencies and other variables beyond our control. A significant further increase in domestic steel capacity or foreign imports could adversely affect our sales, financial results and cash flows. In addition, recent increases in the market prices of iron ore products could cause new producers to enter the market or existing producers to expand productive capacity. Excess iron ore supply combined with reduced global steel demand, including in China, could lead to lower iron ore prices, which would typically contribute to lower steel prices, as iron ore is a principal steelmaking raw material. Downward pressure on iron ore and/or steel prices could have an adverse effect on our results of operations, financial condition and profitability.

Severe financial hardship or bankruptcy of one or more of our major customers or key suppliers could adversely affect our business operations and financial performance.

Sales and operations of a majority of our customers are sensitive to general economic conditions, especially, with respect to our steel customers, as they affect the North American automotive, housing, construction, appliance, energy and other industries. Some of our customers are highly leveraged. If there is a significant weakening of current economic conditions, whether because of operational, cyclical or other issues, including the COVID-19 pandemic, it could impact significantly the creditworthiness of our customers and lead to other financial difficulties or even bankruptcy filings by our customers. Failure to receive payment from our customers for products that we have delivered could adversely affect our results of operations, financial condition and liquidity. The concentration of customers in a specific industry, such as the automotive industry, may increase our risk because of the likelihood that circumstances may affect multiple customers at the same time. For example, during the first half of 2020, the automotive industry was significantly disrupted by the COVID-19 pandemic, which concurrently adversely impacted multiple customers. Such events could cause us to experience lost sales or losses associated with the potential inability to collect all outstanding accounts receivable and reduced liquidity. Similarly, if our key suppliers face financial hardship or need to operate in bankruptcy, such suppliers could experience operational disruption or even face liquidation, which could result in our inability to secure replacement raw materials on a timely basis, or at all, or cause us to incur increased costs to do so. Such events could adversely impact our operations, financial results and cash flows.

II. REGULATORY RISKS

U.S. government actions on trade agreements and treaties, laws, regulations or policies affecting trade could lead to lower or more volatile global steel or iron ore prices, impacting our profitability.

In recent years, the U.S. government has altered its approach to international trade policy, both generally and with respect to matters directly and indirectly affecting the steel industry, including by undertaking certain unilateral actions affecting trade, renegotiating existing bilateral or multilateral trade agreements, and entering into new agreements or treaties with foreign countries. For example, in March 2018, the U.S. government issued a proclamation pursuant to Section 232 imposing a 25% tariff on imported steel that was being unfairly traded by certain foreign competitors at artificially low prices. In retaliation against the Section 232 tariffs, the European Union subsequently imposed its own tariffs against certain steel products and other goods imported from the U.S. Moreover, in light of the U.S. government leadership changes resulting from the November 2020 federal congressional and presidential elections, it is currently uncertain what changes, if any, the U.S. government may make to its recent tariff and trade policies and priorities. If, for example, the Section 232 tariffs are removed or substantially lessened, whether through legal challenge, legislation, executive action or otherwise, imports of foreign steel would likely increase and steel prices in the U.S. would likely fall, which could materially adversely affect our sales, financial results and cash flows.

In addition, during 2020, the USMCA was implemented among the U.S., Mexico and Canada in place of the North American Free Trade Agreement. Because all of our steel manufacturing facilities are located in North America and one of our principal markets is automotive manufacturing in North America, we believe that the USMCA has the potential to positively impact our business by incentivizing automakers and other manufacturers to increase manufacturing production in North America and to use North American steel. However, it is difficult to predict the short- and long-term implications of changes in trade policy and, therefore, whether the USMCA or other new or renegotiated trade agreements, treaties, laws, regulations or policies that may be implemented in connection with the recent U.S. government leadership changes, or otherwise, will have a beneficial or detrimental impact on our business and our customers’ and suppliers’ businesses. Adverse effects could occur directly from a disruption to trade and commercial transactions and/or indirectly by adversely affecting the U.S. economy or certain sectors of the economy, impacting demand for our customers’ products and, in turn, negatively affecting demand for our products. Important

22

links of the supply chain for some of our key customers, including automotive manufacturers, could be negatively impacted by the USMCA or other new or renegotiated trade agreements, treaties, laws, regulations or policies. Any of these actions and their direct and indirect impacts could materially adversely affect our sales, financial results and cash flows.

Although we may currently benefit from certain antidumping and countervailing duty orders, any such relief is subject to periodic reviews and challenges, which can result in revocation of the orders or reduction of the duties. In addition, previously granted and future petitions for trade relief may not be successful or fully effective at preventing harm. Even if received, it is uncertain if any relief will be continued in the future or will be adequate to counteract completely the harmful effects of unfairly traded imports.

We are subject to extensive governmental regulation, which imposes, and will continue to impose, potential significant costs and liabilities on us. Future laws and regulations or the manner in which they are interpreted and enforced could increase these costs and liabilities or limit our ability to produce our raw materials and products.

New laws or regulations, or changes in existing laws or regulations, including the response of federal, state, local and foreign governments to the COVID-19 pandemic or arising out of the changes in U.S. government leadership resulting from the November 2020 elections, or the manner of their interpretation or enforcement, could increase our cost of doing business and restrict our ability to operate our businesses or execute our strategies. This includes, among other things, changes in the interpretation of MSHA regulations, such as workplace exam rules or safety around mobile equipment, reevaluation of the National Ambient Air Quality Standards, such as revised nitrogen dioxide, sulfur dioxide, lead, ozone and particulate matter criteria, changes in the interpretation of OSHA regulations, such as standards for occupational exposure to noise, certain chemicals or hazardous substances and infectious diseases, and the possible taxation under U.S. law of certain income from foreign operations.

In addition, we and our operations are subject to various international, foreign, federal, state, provincial and local laws and regulations relating to protection of the environment and human health and safety, including those relating to air quality, water pollution, plant, wetlands, natural resources and wildlife protection (including endangered or threatened species), reclamation, remediation and restoration of properties and related surety bonds or other financial assurances, land use, the discharge of materials into the environment, the effects that industrial operations and mining have on groundwater quality, conductivity and availability, the management of electrical equipment containing polychlorinated biphenyls, and other related matters. Compliance with numerous governmental permits and approvals is required for our operations. We cannot be certain that we have been or will be at all times in complete compliance with such laws, regulations, permits and approvals. If we violate or fail to comply with these laws, regulations, permits or approvals, we could be fined, required to cease operations, subject to criminal or civil liability, or otherwise sanctioned by regulators. In particular, federal or state regulatory agencies have the authority, under certain circumstances following significant health and safety incidents, such as fatalities, to order a facility to be temporarily or permanently closed. Compliance with the complex and extensive laws and regulations to which we are subject imposes substantial costs on us, which could increase over time because of heightened regulatory oversight, adoption of more stringent environmental, health and safety standards and greater demand for remediation services leading to shortages of equipment, supplies and labor, as well as other factors.

Specifically, there are several notable proposed or recently enacted rulemakings or activities to which we would be subject or that would further regulate and/or tax us and our customers, which may also require us or our customers to reduce or otherwise change operations significantly or incur significant additional costs, depending on their ultimate outcome. These emerging or recently enacted rules, regulations and policy guidance include, but are not limited to: governmental regulations imposed in response to the COVID-19 pandemic; trade regulations, such as the USMCA and/or other trade agreements, treaties or policies; tariffs, such as the 25% tariff on imported steel imposed under Section 232; Minnesota’s potential revisions to the sulfate wild rice water quality standard; evolving water quality standards for selenium and conductivity; scope of the Clean Water Act and the definition of “Waters of the United States”; Minnesota’s Mercury TMDL and associated rules governing mercury air emission reductions; Climate Change and GHG Regulation; the Regional Haze FIP Rule; and the regulation of discharges to water. In addition, the Biden Administration has indicated via executive orders and in campaign statements that it will propose more stringent environmental regulation, in particular related to climate change. Any new or more stringent legislation, regulations, rules, interpretations or orders, when enacted and enforced, could have a material adverse effect on our business, results of operations, financial condition or profitability.

Our operations may be impacted by the recent enactment, and ongoing consideration, of significant federal and state laws and regulations relating to certain mine-related issues, such as the stability of tailings basins, mine drainage and fill activities, reclamation and safety in underground mines. With respect to underground mines, for

23

example, these laws and regulations include requirements for constructing and maintaining caches for the storage of additional self-contained self-rescuers throughout underground mines; installing rescue chambers in underground mines; continuous tracking of and communication with personnel in the mines; installing cable lifelines from the mine portal to all sections of the mine to assist in emergency escape; submission and approval of emergency response plans; and additional safety training. Additionally, there are requirements for the prompt reporting of accidents and increased fines and penalties for violations of these and existing regulations. These laws and regulations may cause us to incur substantial additional costs.

Additionally, our operations are subject to the risks of doing business abroad and we must comply with complex foreign and U.S. laws and regulations, which may include, but are not limited to, the Foreign Corrupt Practices Act and other anti-bribery laws, regulations related to import/export and trade controls, the European Union’s General Data Protection Regulation and other U.S. and foreign privacy regulations, and transportation and logistics regulations. These laws and regulations may increase our costs of doing business in international jurisdictions and expose our operations and our employees to elevated risk. We require our employees, contractors and agents to comply with these and all other applicable laws and regulations, but failure to do so could result in possible administrative, civil or criminal liability and reputational harm to us and our employees. We may also be indirectly affected through regulatory changes that impact our customers, which in turn could reduce the quantity of our products they demand or the prices for our products they are willing to pay. Regulatory changes that impact our suppliers could decrease the supply of products or availability of services they sell to us or could increase the price they demand for products or services they sell to us.

Our operations inadvertently may impact the environment or cause exposure to hazardous substances, which could result in material liabilities to us.

Our operations currently use, and have in the past used, hazardous materials, and, from time to time, we have generated solid and hazardous waste. We have been, and may in the future be, subject to claims under international, foreign, federal, state, provincial and local laws and regulations for toxic torts, natural resource damages and other damages as well as for the investigation and clean-up of soil, surface water, sediments, groundwater and other natural resources and reclamation of properties. Such claims for damages and reclamation may arise out of current or former conditions at sites that we or our acquired companies currently own, lease or operate, as well as sites that we or our acquired companies formerly owned, leased or operated, and at contaminated sites that are or have been owned, leased or operated by our joint venture partners. We may also have liability for contamination at third-party sites where we have sent hazardous wastes. Our liability for these claims may be strict and/or joint and several, such that we may be held responsible for more than our share of the contamination or other damages, or even for entire claims regardless of fault. We are currently subject to potential liabilities relating to investigation and remediation activities at certain sites. In addition to sites currently owned, leased or operated, these include sites where we formerly conducted raw material processing or other operations, inactive sites that we currently own, formerly owned predecessor sites, acquired sites, leased land sites and third-party waste disposal sites. We may be named as a potentially responsible party at other sites in the future and we cannot be certain that the costs associated with these additional sites will not exceed any reserves we have established or otherwise be material.

We also are subject to claims asserting bodily injuries arising from alleged exposure to hazardous substances. For example, certain of our subsidiaries have been named in lawsuits claiming exposure to asbestos, many of which have been dismissed and/or settled for non-material amounts. It is likely that similar types of claims will continue to be filed in the future.

We may be unable to obtain, maintain, renew or comply with permits necessary for our operations or be required to provide additional financial assurances, which could reduce our production, cash flows, profitability and available liquidity.

We must obtain, maintain and comply with numerous permits that require approval of operational plans and impose strict conditions on various environmental, health and safety matters in connection with our steel production and processing and mining and other operations. These include permits issued by various federal, state, provincial, foreign and local agencies and regulatory bodies. The permitting rules are complex and may change over time, making our ability to comply with the applicable requirements more difficult or impractical and costly, possibly precluding the continuance of ongoing operations or the development of future operations. Interpretations of rules may also change over time and may lead to requirements, such as additional financial assurance, making it costlier to comply. For example, heightened levels of regulatory oversight with respect to our coal operations acquired as part of the AM USA Transaction could impact, delay or disrupt our ability to obtain new or renewed permits or modifications to existing permits.

24

In addition, the public, including special interest groups and individuals, have certain rights under various statutes to comment upon, submit objections to, and otherwise engage in the permitting process, including bringing citizens’ lawsuits to challenge such permits or activities. Accordingly, required permits may not be issued or renewed in a timely fashion (or at all), or permits issued or renewed may include conditions that we cannot meet or otherwise be conditioned in ways that may restrict our ability to conduct our production and mining activities efficiently or include requirements for additional financial assurances that we may not be able to provide on commercially reasonable terms (or at all), which could reduce available borrowing capacity under our ABL Facility. Such conditions, restrictions or requirements could reduce our production, cash flows, profitability or liquidity.

III. FINANCIAL RISKS

Our existing and future indebtedness may limit cash flow available to invest in the ongoing needs of our businesses, which could prevent us from fulfilling our obligations under our senior notes, ABL Facility and other debt, and we may be forced to take other actions to satisfy our obligations under our debt, which may not be successful.

As of December 31, 2020, we had $5,595 million aggregate principal amount of long-term debt outstanding, $2,195 million of which was secured (excluding $247 million of outstanding letters of credit and $335 million of finance leases), and $112 million of cash on our balance sheet. On December 9, 2020, in connection with the consummation of the AM USA Transaction, we amended our ABL Facility to, among other things, increase the tranche A revolver commitments available under the ABL Facility by an additional $1,500 million. After giving effect to this amendment, the aggregate principal amount of tranche A revolver commitments under our ABL Facility is $3,350 million, and the aggregate principal amount of tranche B revolver commitments under our ABL Facility remains at $150 million. As of December 31, 2020, $1,510 million was outstanding under our ABL Facility, and the principal amount of letters of credit obligations and other commitments totaled $247 million. As of December 31, 2020, the available borrowing capacity on our ABL Facility was $1,743 million.

We dedicate a portion of our cash flow from operations to the payment of debt service, reducing the availability of our cash flow to fund capital expenditures, acquisitions or strategic development initiatives, and other general corporate purposes. Our ability to make scheduled payments on or to refinance our debt obligations depends on our ability to generate cash in the future and our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control, including the impact of the COVID-19 pandemic. There can be no assurance that we will maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our debt. In addition, any failure to comply with covenants in the instruments governing our debt could result in an event of default that, if not cured or waived, would have a material adverse effect on us.

Our level of indebtedness could have further consequences, including, but not limited to, increasing our vulnerability to adverse economic or industry conditions, placing us at a competitive disadvantage compared to other businesses in the industries in which we operate that are not as leveraged and that may be better positioned to withstand economic downturns, limiting our flexibility to plan for, or react to, changes in our businesses and the industries in which we operate, and requiring us to refinance all or a portion of our existing debt. We may not be able to refinance on commercially reasonable terms or at all, and any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, making it more difficult to obtain surety bonds, letters of credit or other financial assurances that may be demanded by our vendors or regulatory agencies, particularly during periods in which credit markets are weak.

A portion of our borrowing capacity and outstanding indebtedness bears interest at a variable rate based on LIBOR. There is considerable uncertainty regarding the publication of LIBOR beyond 2021. The uncertainty regarding the future of LIBOR, as well as the transition from LIBOR to another benchmark rate or rates, could have adverse impacts on our outstanding debt that currently uses LIBOR as a benchmark rate and, in turn, could adversely affect our financial condition and results of operations.

If we are unable to service our debt obligations, we could face substantial liquidity problems and we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital, including additional secured or unsecured debt, or restructure or refinance our debt, and we may be unable to continue as a going concern. We may be unable to consummate any proposed asset sales or recover the carrying value of these assets, and any proceeds may not be adequate to meet any debt service obligations then due. Any of these examples potentially could have a material adverse impact on our results of operations, profitability, shareholders’ equity and capital structure.

25

Changes in credit ratings issued by nationally recognized statistical rating organizations could adversely affect our cost of financing and the market price of our securities.

Credit rating agencies could downgrade our ratings due to various developments, including matters arising out of the AK Steel Merger or the AM USA Transaction, incurring additional indebtedness and other factors specific to our businesses, a prolonged cyclical downturn in the steel and mining industries, whether due to the COVID-19 pandemic or otherwise, or macroeconomic trends (such as global or regional recessions), and trends in credit and capital markets more generally. Any decline in our credit ratings may result in an increase to our cost of future financing or limit our access to the capital markets, which could harm our financial condition, hinder our ability to refinance existing indebtedness on acceptable terms, or have an adverse effect on the market price of our securities and the terms under which we purchase goods and services.

Our actual operating results may differ significantly from our guidance.

From time to time, we release guidance, including that set forth under “Management’s Discussion and Analysis of Financial Condition and Results of Operations–Outlook” in our Annual Reports on Form 10-K and our Quarterly Reports on Form 10-Q, regarding our future performance. This guidance, which consists of forward-looking statements, is prepared by our management and is qualified by, and subject to, the assumptions and the other information included in our Annual Reports on Form 10-K and our Quarterly Reports on Form 10-Q. Our guidance is not prepared with a view toward compliance with published guidelines of the American Institute of Certified Public Accountants, and neither our independent registered public accounting firm nor any other independent or outside party compiles or examines the guidance and, accordingly, no such person expresses any opinion or any other form of assurance with respect thereto.

Guidance is based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. The principal reason that we release such data is to provide a basis for our management to discuss our business outlook with analysts and investors. We do not accept any responsibility for any projections or reports published by any such third parties.

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results will vary from the guidance. Investors should also recognize that the reliability of any forecasted financial data diminishes the further in the future that the data are forecast. In light of the foregoing, investors are urged to put the guidance in context and not to place undue reliance on it.

Any failure to successfully implement our operating strategy or the occurrence of any of the risks described in our Annual Reports on Form 10-K or our Quarterly Reports on Form 10-Q could result in actual operating results being different than the guidance, and such differences may be adverse and material.

Our assets as of December 31, 2020 include a deferred tax asset, the full value of which we may not be able to realize.

We recognize deferred tax assets and liabilities based on differences between the financial statement carrying amounts and the tax basis of assets and liabilities. At December 31, 2020, the net deferred tax asset was $492 million, primarily related to U.S. NOLs. We regularly review our deferred tax assets for recoverability based on our history of earnings, expectations for future earnings and expected timing of reversals of temporary differences. Realization of deferred tax assets ultimately depends on the existence of sufficient taxable income. We believe the recorded net deferred tax asset at December 31, 2020, is fully realizable based on our expected future earnings. However, our assumptions and estimates are inherently subject to business, economic and competitive uncertainties and contingencies, many of which are beyond our control and some of which may change. As a result, we could ultimately lose a portion of our deferred tax asset related to NOLs due to expiration, which could have a material adverse effect on our results of operations and cash flows.

The ability to use our NOLs and certain other tax attributes to offset future taxable income may be subject to certain limitations.

If a corporation undergoes an “ownership change” within the meaning of Section 382 of the IRC, the corporation’s NOLs and certain other tax attributes arising before the “ownership change” are subject to limitations after the “ownership change.” An “ownership change” under Section 382 of the IRC generally occurs if one or more

26

shareholders or groups of shareholders who own at least 5% of the corporation’s equity increase their ownership in the aggregate by more than 50 percentage points over their lowest ownership percentage within a rolling period that begins on the later of three years prior to the testing date and the date of the last “ownership change.” If an “ownership change” were to occur, Section 382 of the IRC would impose an annual limit on the amount of pre-ownership change NOLs and other tax attributes the corporation could use to reduce its taxable income, potentially increasing and accelerating the corporation’s liability for income taxes, and also potentially causing tax attributes to expire unused. The amount of the annual limitation is determined based on a corporation’s value immediately prior to the ownership change.

As of December 31, 2020, after taking into account limitations (or disallowance) on use, we had $2,510 million and $1,009 million of available U.S. federal and state NOLs, respectively, including amounts acquired in the AK Steel Merger. The use of our common shares in the Acquisitions in conjunction with subsequent issuances or sales of our shares (including transactions that are outside of our control) could cause us to experience an “ownership change.” If we experience an “ownership change” under Section 382 of the IRC, further limitations (or disallowances) may apply and similar rules may also apply under state and foreign laws. Consequently, we may not be able to utilize a material portion of our NOLs and other tax attributes, which, in addition to increasing our U.S. federal and state income tax liability, could adversely affect our share price, financial condition, results of operations and cash flows.

Holders of our common shares may not receive dividends on their common shares.

We are not required to declare cash dividends on our common shares and, in April 2020, we announced the suspension of future dividends. Holders of our common shares are entitled to receive only such dividends as our Board may from time to time declare out of funds legally available for such payments. We are incorporated in Ohio and governed by the Ohio General Corporation Law, which allows a corporation to pay dividends, in general, in an amount that cannot exceed its surplus, as determined under Ohio law. Our ability to pay dividends will be subject to our future earnings, capital requirements and financial condition, as well as our compliance with covenants and financial ratios related to existing or future indebtedness, business prospects and other factors that our Board may deem relevant. Additionally, our ABL Facility contains, and agreements governing any of our future debt may contain, covenants and other restrictions that, in certain circumstances, could limit the level of dividends that we are able to pay on our common shares.

IV. OPERATIONAL RISKS

We face significant risks relating to our recent acquisitions of the AK Steel and ArcelorMittal USA businesses.

During 2020, we completed both the AK Steel Merger and the AM USA Transaction. These recent transformative acquisitions involve a number of significant risks and uncertainties that may adversely affect us, including the following:

•inability to realize anticipated synergies or other expected benefits or cost savings;

•additional debt incurred or assumed in connection with the acquisitions could limit our financial flexibility, including our ability to acquire additional assets and make further strategic investments in the future;

•diversion of financial resources to the new operations or acquired businesses;

•assumption of substantial additional environmental exposures, commitments, contingencies and remediation and reclamation projects;

•liabilities for acquired pension and OPEB obligations, which could require us to make significant cash expenditures and funding contributions in excess of current estimates and contribution rates;

•impairment of recorded tangible and intangible asset values, including goodwill, could result in material non-cash charges to our results of operations in the future;

•failure to successfully integrate acquired systems, business processes, policies and procedures;

•exposure to unknown liabilities and unforeseen costs that were not discovered during due diligence;

•loss of human capital resources and support services historically provided by ArcelorMittal and potential failure of ArcelorMittal or its affiliates to perform under various contracts entered into in connection with the AM USA Transaction, including the intellectual property license agreement, slab supply agreement and

27

transition services agreement, which could adversely impact our integration of the ArcelorMittal USA operations;

•potential loss of key employees, suppliers or customers; and

•other challenges associated with managing the larger, more complex and integrated combined businesses.

If one or more of these risks and uncertainties were to materialize, we could experience reduced sales, higher costs, lower profitability and other adverse impacts to our operations and businesses.

In addition, in connection with the closing of the AM USA Transaction, we issued approximately 78 million of our common shares to an indirect, wholly owned subsidiary of ArcelorMittal, equating to approximately 16% of our then-outstanding common shares. On February 11, 2021, in connection with our sale of 20 million of our common shares in an underwritten public offering, such subsidiary of ArcelorMittal, as a selling shareholder in the offering, sold 40 million of our common shares. We believe such subsidiary of ArcelorMittal continues to hold approximately 38 million of our common shares, equating to approximately 8% of our outstanding common shares following completion of such offering. Although ArcelorMittal and its affiliates are subject to certain restrictions and requirements under an Investor Rights Agreement with respect to its and its affiliates' ownership and voting of our common shares, at such a level of beneficial ownership, ArcelorMittal and its affiliates may be able to exert influence over us and actions requiring the approval of our common shareholders. Under the Investor Rights Agreement, ArcelorMittal and its affiliates are permitted to transfer all of our common shares held by them, subject to certain restrictions on transfers to persons whose beneficial ownership of our common shares following any such transfer would exceed 5% or 10% of our then-outstanding common shares. Sales of our shares by ArcelorMittal and its affiliates or other shareholders, coupled with the increase in the outstanding number of our common shares, may affect the market for, and the market price of, our common shares in an adverse manner.

We also issued 583,273 shares of Series B Preferred Stock to an indirect, wholly owned subsidiary of ArcelorMittal in connection with the closing of the AM USA Transaction. Pursuant to the terms of the Series B Preferred Stock, from and after the 24-month anniversary of the issue date of the Series B Preferred Stock (the “24-Month Anniversary”), each holder of a share of Series B Preferred Stock is entitled to receive cash dividends (the “Additional Dividends”) that will accrue and compound at a significant rate. Although the Series B Preferred Stock is redeemable at our option 180 days after the issue date, the agreements governing our debt may restrict us from paying the redemption price at any given time. If we are unable to redeem the Series B Preferred Stock prior to the 24-Month Anniversary and we become obligated to pay the Additional Dividends, we may be required to divert financial resources from our operations or borrow additional debt in order to satisfy such obligations, which could have a material adverse effect on our business, financial condition and results of operations.

We have limited ability to control our joint venture operations, rely on our joint venture partners to meet their payment obligations, and are subject to risks involving the acts or omissions of our joint venture partners.

As part of the AM USA Transaction, we acquired ArcelorMittal USA’s interest in Hibbing and again became the manager of Hibbing, which we co-own with U.S. Steel. In our steel business, we are party to various joint venture arrangements primarily related to downstream steel processing operations. Due to shared ownership, we have limited ability to control our joint venture operations, and we cannot control the actions of our joint venture partners. Accordingly, we rely on our joint venture partners to make their required capital contributions and to pay for their share of joint venture obligations. If our joint venture partners experience financial hardship or fail to perform their obligations, we may be required to assume additional material obligations to minimize operational disruption or as part of a liquidation, including significant capital contributions, costs of environmental remediation, and pension and OPEB obligations.

Our operating expenses could increase significantly if the price of raw materials, electrical power, fuel or other energy sources increases.

Our operations require significant use of energy and raw materials. Energy expenses are sensitive to changes in electricity, energy transportation and fuel prices, including diesel fuel and natural gas. Although we are self-sufficient in iron ore, other raw materials or production inputs where we are wholly or partially dependent on third-party suppliers include industrial gases, graphite electrodes, scrap, chrome, zinc, coke and coal. Prices for electricity, natural gas, fuel oils and raw materials can fluctuate widely with availability and demand levels from other users, including fluctuations caused by the impact of the COVID-19 pandemic. During periods of peak usage, although some operations have contractual arrangements in place whereby they receive certain offsetting payments in exchange for electricity load reduction, supplies of energy and raw materials in general may be curtailed and we may not be able to purchase them at historical rates. A disruption in the transmission of energy, inadequate energy transmission

28

infrastructure, or the termination of any of our energy supply contracts could interrupt our energy supply and adversely affect our operations. While we have some long-term contracts with electrical, natural gas and raw material suppliers, we are exposed to fluctuations in energy, natural gas and raw material costs that can affect our production costs. As an example, our Toledo direct reduction plant is subject to changes in the market price of natural gas, which is a key input in the direct reduction of iron ore pellets to produce HBI. We enter into many market-based pricing supply contracts for electricity, natural gas and diesel fuel for use in our operations. Those contracts expose us to price increases in energy costs, which could cause our profitability to decrease significantly. In addition, U.S. public utilities may impose rate increases and pass through additional capital and operating cost increases to their customers related to new or pending U.S. environmental regulations or other charges that may require significant capital investment and use of cleaner fuels in the future. In particular, the recent decision of the U.S. Court of Appeals for the District of Columbia vacating and remanding the Affordable Clean Energy Rule, as well as recent executive orders from President Biden regarding the environment and climate change, indicate that new or revised regulations under the Biden Administration could result in rate increases from U.S. utilities.

The majority of our steel shipments are sold under contracts that do not allow us to pass through all increases in raw materials, supplies and energy costs. Some of our steel shipments to contract customers include variable-pricing mechanisms allowing us to adjust the total sales price based on changes in specified raw materials, supplies and energy costs. Those adjustments, however, rarely reflect all of our underlying raw materials, supplies and energy cost changes. The scope of the adjustment may also be limited by the terms of the negotiated language, including limitations on when the adjustment occurs. Our need to consume existing inventories may also delay the impact of a change in prices of raw materials or supplies. Significant changes in raw material costs may also increase the potential for inventory value write-downs in the event of a reduction in selling prices and our inability to realize the cost of the inventory.

Steelmaking facility or mine closures entail substantial costs. If our assumptions underlying our accruals for closure costs prove to be inaccurate or we prematurely close one or more of our facilities or mines, our results of operations and financial condition would likely be adversely affected.

If faced with overcapacity in the market or other adverse conditions, including as a result of the COVID-19 pandemic, we may seek to rationalize assets through asset sales, temporary shutdowns, indefinite idles or facility closures. If we indefinitely idle or permanently close any of our facilities or mines, our production and revenues would be reduced unless we were able to increase production at our other facilities or mines in an offsetting amount, which may not be possible, and could result in customers responding negatively by taking current or future business away from us if we seek to transition production to a different facility. Alternatively, we could fail to meet customer specifications at the facilities to which products are transitioned, resulting in customer dissatisfaction or claims.

The closure of a steelmaking facility or mining operation involves significant closure costs, including reclamation and other environmental costs, the costs of terminating long-term obligations, including customer, energy and transportation contracts and equipment leases, and certain accounting charges, including asset impairment and accelerated depreciation. In addition, a permanent steelmaking facility or mine closure could accelerate and significantly increase employment legacy costs, including our expense and funding costs for pension and OPEB obligations and multiemployer pension withdrawal liabilities. A number of employees would be eligible for immediate retirement under special eligibility rules that apply upon a steelmaking facility or mine closure. All employees eligible for immediate retirement under the pension plans at the time of the permanent closure also could be eligible for OPEB, thereby accelerating our obligation to provide these benefits. Certain closures would precipitate a pension closure liability significantly greater than an ongoing operation liability and may trigger certain severance liability obligations.

We base our assumptions regarding the life of our mines on detailed studies we perform from time to time, but those studies and assumptions are subject to uncertainties and estimates that may not be accurate. We recognize the costs of reclaiming open pits, stockpiles, tailings ponds, roads and other mining support areas based on the estimated mining life of our property. If our assumptions underlying our accruals for closure costs, including reclamation and other environmental costs, prove to be inaccurate or insufficient, or our liability in any particular year is greater than currently anticipated, our results of operations and financial condition could be adversely affected. In addition, if we were to significantly reduce the estimated life of any of our mines, the mine closure costs would be applied to a shorter period of production, which would increase costs per ton produced and could adversely affect our results of operations and financial condition.

29

Our sales and competitive position depend on the ability to transport our products to our customers at competitive rates and in a timely manner.

Disruption of the lake, rail and/or trucking transportation services because of weather-related problems, including ice and winter weather conditions on the Great Lakes or St. Lawrence Seaway, climate change, strikes, lock-outs, driver shortages and other disruptions in the trucking industry, rail network constraints, global or domestic pandemics or epidemics (such as the COVID-19 pandemic) or other infectious disease outbreaks, in each case causing a business disruption, or other events and lack of alternative transportation options could impair our ability to move products internally among our facilities and to supply products to our customers at competitive rates or in a timely manner and, thus, could adversely affect our sales, margins and profitability. Further, dredging issues and environmental changes, particularly at Great Lakes ports, could impact adversely our ability to move certain of our products or result in higher freight rates. Similarly, we depend on third-party transportation services for delivery of raw materials to us, and failures or delays in delivery would have an adverse effect on our ability to maintain steady-state production operations to meet customer obligations.

Natural or human-caused disasters, weather conditions, disruption of energy, unanticipated geological conditions, equipment failures, infectious disease outbreaks, and other unexpected events may lead our customers, our suppliers or our facilities to curtail production or shut down operations.

Operating levels within our industry and the industries of our customers and suppliers are subject to unexpected conditions and events that are beyond the industries’ control. Those events, including the occurrence of an infectious disease or illness, such as the COVID-19 pandemic, could cause industry members or their suppliers to curtail production or shut down a portion or all of their operations, which could reduce the demand for our products and adversely affect our sales, margins and profitability. For example, the temporary production shutdowns in the automotive industry during 2020 as a result of the COVID-19 pandemic and associated reduction in demand for our products led to our decision to temporarily idle certain steelmaking facilities and iron ore mines.

Our operating levels are subject to conditions beyond our control that can delay deliveries or increase the cost of production for varying lengths of time. Factors that could cause production disruptions could include adverse weather conditions (for example, extreme winter weather, tornadoes, floods, and the lack of availability of process water due to drought) and natural and man-made disasters, lack of adequate raw materials, energy or other supplies, and infectious disease outbreaks, such as the COVID-19 pandemic. In addition, factors that could adversely impact production and operations at our mining operations include tailings dam failures, pit wall failures, unanticipated geological conditions, including variations in the amount of rock and soil overlying deposits of iron ore and coal, variations in rock and other natural materials, and variations in geologic conditions and processing changes.

Our mining operations, processing facilities, steelmaking and logistics operations depend on critical pieces of equipment. This equipment may, on occasion, be out of service because of unanticipated failures or unplanned outages. In addition, most of our mines and production and processing facilities have been in operation for several decades, and the equipment is aged. In the future, we may experience additional lengthy shutdowns or periods of reduced production because of equipment failures. Further, remediation of any interruption in production capability may require us to make large capital expenditures that could have a negative impact on our profitability and cash flows. Our business interruption insurance would not cover all of the lost revenues associated with equipment failures. Longer-term business disruptions could result in a loss of customers, which could adversely affect our future sales levels and revenues.

Many of our production facilities and mines are dependent on one source for electric power, natural gas, industrial gases and/or certain other raw materials or supplies. A significant interruption in service from our suppliers due to the COVID-19 pandemic, terrorism or sabotage, weather conditions, natural disasters, equipment failure or any other cause could result in substantial losses that may not be fully recoverable, either from our business interruption insurance or responsible third parties.

We incur certain costs when production capacity is idled, as well as increased costs to resume production at previously idled facilities.

Our decisions concerning which facilities to operate and at what production levels are made based in part upon our customers’ orders for products, as well as the quality, performance capabilities and cost of our operations. During depressed market conditions, we may concentrate production at certain facilities and not operate others in response to customer demand, and as a result we may incur idle costs that could offset our anticipated savings from not operating the idled facility. For example, due to reduced demand as a result of the COVID-19 pandemic, certain of our steelmaking facilities and iron ore mines were temporarily idled during portions of 2020 and we continued to incur

30

certain fixed costs at those facilities. We cannot predict whether our operations will experience additional disruptions in the future.

When we restart idled facilities, we incur certain costs to replenish inventories, prepare the previously idled facilities for operation, perform the required repair and maintenance activities, and prepare employees to return to work safely and resume production responsibilities. The amount of any such costs can be material, depending on a variety of factors, such as the period of idle time, necessary repairs and available employees, and is difficult to project.

We may not have adequate insurance coverage for some business risks.

Our operations are generally subject to a number of hazards and risks, which could result in personal injury or damage to, or destruction of, equipment, properties or facilities. The insurance that we maintain to address risks that are typical in our businesses may not provide adequate coverage. Insurance against some risks, such as liabilities for environmental pollution, tailings basin breaches, or certain hazards or interruption of certain business activities, may not be available at an economically reasonable cost, or at all. Even if available, we may self-insure where we determine it is most cost effective to do so. As a result, despite the insurance coverage that we carry, accidents or other negative developments involving our production, mining, processing or transportation activities causing losses in excess of policy limits, or losses arising from events not covered under insurance policies, could have a material adverse effect on our financial condition and cash flows.

A disruption in or failure of our IT systems, including those related to cybersecurity, could adversely affect our business operations and financial performance.

We rely on the accuracy, capacity, integrity and security of our IT systems for the operation of many of our business processes and to comply with regulatory, legal and tax requirements. While we maintain some of our critical IT systems, we are also dependent on third parties to provide important IT services relating to, among other things, operational process technology at our facilities, human resources, electronic communications and certain finance functions. Further, in connection with the Acquisitions, we inherited certain legacy hardware and software IT systems that can be supported only by a very limited number of specialists in the market, and our increased reliance on these legacy IT systems may increase the risk of IT system disruption or failure, which could adversely affect our operations.

Despite the security measures that we have implemented, including those related to cybersecurity, our IT systems could be breached or damaged by computer viruses, natural or man-made incidents or disasters, or unauthorized physical or electronic access or intrusions. Though we have controls in place, we cannot provide assurance that a cyberattack will not occur. Furthermore, we may have little or no oversight with respect to security measures employed by third-party service providers, which may ultimately prove to be ineffective at countering threats. We may also experience increased risk of IT system failures or cyberattacks as many of our employees continue to work from home as part of our response to the COVID-19 pandemic. In addition, we may experience increased risk of IT system failures or cyberattacks as transitional activities relating to the Acquisitions are in progress, since these activities expose each company to the other’s security vulnerabilities, and because the Acquisitions may attract the attention of potential cyber criminals.

Failures of our IT systems, whether caused maliciously or inadvertently, may result in the disruption of our business processes, or in the unauthorized release of sensitive, confidential, personally identifiable or otherwise protected information, or result in the corruption of data, each of which could adversely affect our businesses. For example, cybersecurity vulnerabilities could result in an interruption of the functionality of our automated manufacturing operating systems, which, if compromised, could cease, threaten, delay or slow down our ability to produce or process steel or any of our other products for the duration of such interruption, which could result in reputational harm and may adversely affect our results of operations, financial condition and cash flows. In addition, any compromise of the security of our IT systems could result in a loss of confidence in our security measures and subject us to litigation, regulatory investigations and negative publicity that could adversely affect our reputation and financial condition. Our customers, suppliers and vendors may also access or store certain of our sensitive information on their IT systems, which, if breached, attacked or accessed by unauthorized persons, could likewise expose our sensitive information and adversely impact our businesses. Furthermore, as cybersecurity threats continue to evolve and become more sophisticated, we may be required to incur significant costs and invest additional resources to protect against and, if required, remediate the damage caused by such disruptions or system failures in the future.

31

V. DEVELOPMENT AND SUSTAINABILITY RISKS

The cost and time to implement a strategic capital project may prove to be greater than originally anticipated.

From time to time, we undertake strategic capital projects, such as our recently-completed Toledo direct reduction plant, in order to enhance, expand or upgrade our production and mining capabilities or diversify our customer base. Our ability to achieve the anticipated production volumes, revenues or otherwise realize acceptable returns on strategic capital projects that we may undertake is subject to a number of risks, many of which are beyond our control, including a variety of market (such as a volatile pricing environment for our products), operational, permitting and labor-related factors. Further, the cost to implement any given strategic capital project ultimately may prove to be greater and may take more time than originally anticipated. Inability to achieve the anticipated results from the implementation of our strategic capital projects, incurring unanticipated implementation costs or penalties, or the inability to meet contractual obligations could adversely affect our results of operations and future earnings and cash flow generation.

We must continually replace reserves depleted by production. Exploration activities may not result in additional discoveries.

Our ability to replenish mineral reserves is important to our long-term viability. Depleted reserves must be replaced by further delineation of existing mineral bodies or by locating new deposits in order to maintain production levels over the long term. Decisions to defer mine development activities may adversely impact our ability to substantially increase future mineral production. Resource exploration and development are highly speculative in nature. Exploration projects involve many risks, require substantial expenditures and may not result in the discovery of sufficient additional mineral deposits that can be mined economically. Once a mineral body is discovered, it may take several years from the initial phases of drilling until production is possible, during which time the economic feasibility of production may change. Substantial expenditures are required to establish recoverable proven and probable reserves and to construct mining and processing facilities. As a result, there is no assurance that current or future exploration programs will be successful, and there is a risk that depletion of reserves will not be offset by discoveries or acquisitions.

We rely on estimates of our recoverable reserves, which is complex due to geological characteristics of the properties and the number of assumptions made.

We regularly evaluate our iron ore and coal reserves based on revenues and costs and update them as required in accordance with SEC regulations. We anticipate further updating our mining properties disclosure in accordance with the SEC’s Final Rule 13-10570, Modernization of Property Disclosures for Mining Registrants, which became effective February 25, 2019, and which rescinds SEC Industry Guide 7 following a two-year transition period, which means that we will be required to comply with the new rule no later than our fiscal year beginning January 1, 2021.

Estimates of reserves and future net cash flows necessarily depend upon a number of variable factors and assumptions, some of which are beyond our control, such as production capacity, effects of regulations by governmental agencies, future prices for iron ore and coal, future industry conditions and operating costs, severance and excise taxes, development costs, and costs of extraction and reclamation. Estimating the quantity and grade of reserves requires us to determine the size, shape and depth of our mineral bodies by analyzing geological data, such as samplings of drill holes. Estimated reserves could be affected by future industry conditions, future changes in the SEC’s mining property disclosure requirements, geological conditions and ongoing mine planning. Actual volume and grade of reserves recovered, production rates, revenues and expenditures with respect to our reserves will likely vary from estimates, and if such variances are material, our sales and profitability could be adversely affected.

Defects in title or loss of any leasehold interests in our mining properties could limit our ability to mine these properties or result in significant unanticipated costs.

Many of our operations are conducted on properties we lease, license or as to which we have easements or other possessory interests. We generally do not maintain title insurance on our properties. A title defect or the loss of any lease, license, easement or other possessory interest for any mining property could adversely affect our ability to mine any associated reserves. In addition, from time to time the rights of third parties for competing uses of adjacent, overlying or underlying lands, such as for roads, easements, public facilities or other mining activities, may affect our ability to operate as planned if our title is not superior or mutually acceptable arrangements cannot be negotiated. Any challenge to our title could delay the exploration and development of some reserves, deposits or surface rights, cause us to incur unanticipated costs, and could ultimately result in the loss of some or all of our interest in those properties.

32

In the event we lose reserves, deposits or surface rights, we may be required to shut down or significantly alter impacted mining operations, thereby affecting future production, revenues and cash flows.

In order to continue to foster growth in our businesses and maintain stability of our earnings, we must maintain our social license to operate with our stakeholders.

Maintaining a strong reputation and consistent operational, environmental and safety track record is vital in order to continue to foster growth and maintain stability in our earnings. As stakeholders’ sustainability expectations increase and regulatory requirements continue to evolve, maintaining our social license to operate becomes increasingly important. Our ability to maintain our reputation and strong operating track record could be threatened, including by challenges relating to the integration of the AK Steel and ArcelorMittal USA businesses or by circumstances outside of our control, such as disasters caused or suffered by other companies in the steel and mining industries. If we are not able to respond effectively to these and other challenges to our social license to operate, our reputation could be damaged significantly. Damage to our reputation could adversely affect our operations and ability to foster growth projects.

VI. HUMAN CAPITAL RISKS

Our profitability could be adversely affected if we fail to maintain satisfactory labor relations.

Our production is dependent upon the efforts of our employees. We are party to labor agreements with various labor unions that represent employees at the majority of our operations. Such labor agreements are negotiated periodically, and, therefore, we are subject to the risk that these agreements may not be able to be renewed on reasonably satisfactory terms. It is difficult to predict what issues may arise as part of the collective bargaining process, and whether negotiations concerning these issues will be successful. Due to union activities or other employee actions, we could experience labor disputes, work stoppages or other disruptions in our production that could affect us adversely. We have labor agreements that will expire at five locations in 2021 and sixteen locations in 2022. If we enter into a new labor agreement with any union that significantly increases our labor costs relative to our competitors or fail to come to an agreement upon expiry, our ability to compete or continuity of production may be materially and adversely affected.

We may encounter labor shortages for critical operational positions, which could adversely affect our ability to produce our products.

We are predicting a long-term shortage of skilled workers in heavy industry and in certain highly specialized IT roles, and competition for the available workers limits our ability to attract and retain employees as well as engage third-party contractors. As our experienced employees retire, we may have difficulty replacing them at competitive wages. In addition, the ongoing COVID-19 pandemic has resulted and may continue to result in increased government restrictions and regulation, including quarantines of our personnel and potential inability to access facilities, which has adversely affected and could continue to adversely affect our operations.

Our expenditures for pension and OPEB obligations could be materially higher than we have predicted if our underlying assumptions differ from actual outcomes, there are regulatory changes or our joint venture partners fail to perform their obligations that relate to employee pension plans.

We provide defined benefit pension plans and OPEB to certain eligible union and non-union employees, including our share of expense and funding obligations with respect to our unconsolidated joint ventures. Our pension and OPEB expenses and our required contributions to our pension and OPEB plans are affected directly by the value of plan assets, the projected and actual rate of return on plan assets, and the actuarial assumptions we use to measure our defined benefit pension plan obligations, including the rate at which future obligations are discounted. We cannot predict whether changing market or economic conditions, regulatory changes or other factors will increase our pension and OPEB expenses or our funding obligations, diverting funds we would otherwise apply to other uses.

We have calculated our unfunded pension and OPEB obligations based on a number of assumptions. If our assumptions do not materialize as expected, cash expenditures and costs that we incur could be materially higher. Moreover, we cannot be certain that regulatory changes will not increase our obligations to provide these or additional benefits. These obligations also may increase substantially in the event of adverse medical cost trends or unexpected rates of early retirement, particularly for bargaining unit retirees. In addition, changes in the laws governing pensions could also materially adversely affect our costs and ability to meet our pension obligations.

33

We also contribute to certain multiemployer pension plans, including the Steelworkers’ Pension Trust, for which we are one of the largest contributing employers. If other contributors were to default on their obligations to contribute to any such plans, we could become liable for additional unfunded contributions to the plans.

In addition, some of the transactions in which we previously sold or otherwise disposed of our non-core assets included provisions transferring certain pension and other liabilities to the purchasers or acquirers of those assets. While we believe that all such transfers were completed properly and are legally binding, if the purchaser fails to fulfill its obligations, we may be at risk that a court, arbitrator or regulatory body could disagree and determine that we remain responsible for pension and other liabilities that we intended to and did transfer.

We depend on our senior management team and other key employees, and the loss of these employees could adversely affect our businesses.

Our success depends in part on our ability to attract, retain, develop and motivate our senior management and key employees. Achieving this objective may be difficult due to a variety of factors, including fluctuations in the global economic and industry conditions, competitors’ hiring practices, cost reduction activities, and the effectiveness of our compensation programs. Competition for qualified personnel can be intense. We must continue to recruit, retain, develop and motivate our senior management and key personnel in order to maintain our business and support our projects. A loss of senior management and key personnel could prevent us from capitalizing on business opportunities, and our operating results could be adversely affected. We are also subject to the risk that the COVID-19 pandemic may impact the health or effectiveness of members of our senior management team or other key employees.

All of our iron ore mining operations are open-pit mines. Additional pit development is underway as required by long-range mine plans. Drilling programs are conducted periodically to collect modeling data and for refining ongoing operations.

Geologic models are developed for all mines to define the major ore and waste rock types. Computerized block models for iron ore are constructed that include all relevant geologic and metallurgical data. These are used to generate grade and tonnage estimates, followed by detailed mine design and life of mine operating schedules.

We currently own or co-own five operating iron ore mines in Michigan and Minnesota, as well as one indefinitely idled mine in Michigan. Following the AM USA Transaction, we now have an aggregate annual production capacity of approximately 28 million long tons of iron ore pellets, including our 85.3% share of the Hibbing mine production. Historically, our share of production capacity was approximately 21 million long tons of iron ore pellets

38

annually. We produced 17 million, 20 million and 20 million long tons of iron ore pellets in 2020, 2019 and 2018, respectively.

Our iron ore mines produce from deposits located within the Biwabik and Negaunee Iron Formation, which are classified as Lake Superior type iron formations that formed under similar sedimentary conditions in shallow marine basins approximately two billion years ago. Magnetite and hematite are the predominant iron oxide ore minerals present, with lesser amounts of goethite and limonite. Quartz is the predominant waste mineral present, with lesser amounts of other chiefly iron bearing silicate and carbonate minerals. The ore minerals liberate from the waste minerals upon fine grinding.

The Hibbing mine is located in the center of Minnesota’s Mesabi Iron Range and is approximately ten miles north of Hibbing, Minnesota, and five miles west of Chisholm, Minnesota. We own an 85.3% interest in the Hibbing mine, which has been operating since 1976. A subsidiary of U.S. Steel owns the remaining 14.7% of the Hibbing mine. Prior to the AM USA Transaction, we owned 23% of Hibbing, ArcelorMittal USA had a 62.3% interest and U.S. Steel had a 14.7% interest. On December 9, 2020, as a result of the AM USA Transaction, we acquired an additional 62.3% ownership stake in the Hibbing mine and became the majority owner and mine manager. Each partner takes its share of production pro rata; however, provisions in the joint venture agreement allow additional or reduced production to be delivered under certain circumstances. In 2020, the Hibbing mine produced 5.5 million long tons of iron ore pellets, of which 1.6 million long tons were for our account. Hibbing owns 3% of the ore reserves and leases 97% via multiple mineral leases having varying expiration dates. Mining leases routinely are renegotiated and renewed as they approach their respective expiration dates. Hibbing operations consist of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, AG mills and magnetic separation to produce a magnetite concentrate, which is then delivered to an on-site pellet plant. From the site, pellets are transported by BNSF rail to a ship loading port at Superior, Wisconsin, operated by BNSF.

The Minorca mine is located in the center of Minnesota’s Mesabi Iron Range near Virginia, Minnesota. In 2020, the mine produced 2.8 million long tons of iron ore pellets, of which approximately 0.2 million long tons were produced during the period subsequent to the AM USA Transaction. We own 100% of the Minorca mine, which has been operating since 1977, and lease 100% of the mineral rights. Mining is conducted on multiple mineral leases having varying expiration dates. Mining leases routinely are renegotiated and renewed as they approach their respective expiration dates. This operation includes a concentrating and pelletizing facility, along with two open pit iron ore mines located approximately seven miles from the processing facilities. The processing operations consist of a crushing facility, a three-line concentration facility and a single-line straight grate pelletizing plant. Pellets are transported by CN rail to ports on Lake Superior and shipped to Indiana Harbor located in East Chicago, Indiana.

The Northshore mine is located in northeastern Minnesota, approximately two miles south of Babbitt, Minnesota, on the northeastern end of the Mesabi Iron Range. Northshore’s processing facilities are located in Silver Bay, Minnesota, near Lake Superior.

Mineral Policy

We have a corporate policy prescribing internal controls and procedures with respect to auditing and estimating of minerals. The procedures contained in the policy include the calculation of mineral estimates at each property by our engineers, geologists and accountants, as well as third-party consultants. Management compiles and reviews the calculations, and once finalized, such information is used to prepare the disclosures for our annual and quarterly reports. The disclosures are reviewed and approved by management, including our chief executive officer and chief financial officer. Additionally, the long-range mine planning and mineral estimates are reviewed annually by our Audit Committee. Furthermore, all changes to mineral estimates, other than those due to production, are adequately documented and submitted to senior operations officers for review and approval. Finally, periodic reviews of long-range mine plans and mineral reserve estimates are conducted at mine staff meetings, senior management meetings and by independent experts.

40

Reserves are defined by SEC Industry Standard Guide 7 as that part of a mineral deposit that could be economically and legally extracted and produced at the time of the reserve determination. All reserves are classified as proven or probable and are supported by life-of-mine plans.

Reserve estimates are based on pricing that does not exceed the three-year trailing average index price of iron ore and coal adjusted to realized price. We evaluate and analyze mineral reserve estimates in accordance with our mineral policy and SEC requirements. The table below identifies the year in which the latest reserve estimate was completed.

Property	Date of Latest Economic Reserve Analysis

Mesabi Metallics amended its complaint to add additional defendants, including, among others, our subsidiary, Cleveland-Cliffs Minnesota Land Development Company LLC ("Cliffs Minnesota Land"), and to add additional claims, including avoidance and recovery of unauthorized post-petition transfers of real estate interests, claims disallowance, civil contempt and declaratory relief. Mesabi Metallics seeks, among other things, unspecified damages and injunctive relief. Cliffs and Cliffs Minnesota Land filed counterclaims against Mesabi Metallics, Chippewa Capital Partners ("Chippewa"), and Thomas M. Clarke ("Clarke") for tortious interference and civil conspiracy, as well as additional claims against Chippewa and Clarke for aiding and abetting tortious interference, for which we seek, among other things, damages and injunctive relief. Our counterclaim against Clarke for libel was dismissed on jurisdictional grounds. The parties filed various dispositive motions on certain of the claims, including a motion for partial summary judgment to settle a dispute over real estate transactions between Cliffs Minnesota Land and Glacier Park Iron Ore Properties LLC ("GPIOP"). A ruling in favor of Cliffs, Cliffs Minnesota Land and GPIOP was issued on July 23, 2018, finding that Mesabi Metallics' leases had terminated and upholding Cliffs' and Cliffs Minnesota Land's purchase and lease of the contested real estate interests. Mesabi Metallics filed a Motion for Leave to File an Interlocutory Appeal, which was denied on September 10, 2019. Discovery is ongoing. We believe the claims asserted against us are without merit, and we intend to continue to vigorously defend against any remaining claims in the lawsuit.

Mesabi Trust Arbitration. On December 9, 2019, Mesabi Trust filed a demand for arbitration with the American Arbitration Association against Northshore and Cleveland-Cliffs Inc. alleging various breaches of a royalty agreement under which Northshore extracts iron ore from Mesabi Trust lands in return for paying royalties to Mesabi Trust. In its demand, Mesabi Trust asserts that we improperly based royalty payments for intercompany sales of DR-grade pellets on artificially low pricing of DR-grade pellet sales to one of our arms’ length third-party customers. Mesabi Trust further asserts that we paid royalties too soon on DR-grade pellets stockpiled at Northshore and destined for shipment to our Toledo direct reduction plant. The allegations also include failure to provide access to information and individuals necessary to determine compliance with the royalty agreement. In addition to seeking damages and costs, Mesabi Trust seeks declarations as to the methodology and timing for calculating royalties on our intercompany DR-grade pellet sales, and that Mesabi Trust should have full and unfettered access to all of our information and employees. During 2020, the parties appointed a three-member arbitration panel and engaged in discovery. The arbitration hearing is scheduled for May 2021. We believe the claims asserted against us are without merit, and we intend to vigorously defend against them.

Certain Legacy Legal Proceedings Relating to our Steel Operations. Certain of our acquired subsidiaries have been named as defendants, among many other named defendants, in numerous lawsuits filed since 1990 claiming injury allegedly resulting from exposure to asbestos. Similar lawsuits seeking monetary relief continue to be filed in various jurisdictions in the U.S., which cases are vigorously defended. Although predictions about the outcome of pending litigation is subject to uncertainties, based upon present knowledge, we believe it is unlikely that the resolution in the aggregate of these claims will have a materially adverse effect on our consolidated results of operations, cash flows or financial condition.

Legal Proceedings Relating to Environmental Matters

SEC regulations require us to disclose certain information about administrative or judicial proceedings involving the environment and to which a governmental authority is a party if we reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. Pursuant to SEC regulations, we use a threshold of $1 million for purposes of determining whether disclosure of any such proceedings is required. We believe that this threshold is reasonably designed to result in disclosure of any such proceedings that are material to our business or financial condition. Applying this threshold, we are disclosing the following environmental proceedings for the period covered by this report:

Dearborn Works Air NOVs. On November 18, 2019, November 26, 2019, and March 16, 2020, EGLE issued NOVs with respect to the basic oxygen furnace electrostatic precipitator at Dearborn Works alleging violations of manganese, lead and opacity limits. We are investigating these claims and will work with EGLE to attempt to resolve

42

them. We intend to vigorously contest any claims that cannot be resolved through a settlement. Until a settlement is reached with EGLE or the claims of the NOVs are otherwise resolved, we cannot reasonably estimate the costs, if any, associated with any potentially required work.

Additional information for this item relating to certain other environmental proceedings may be found under the headings EPA Administrative Order In Re: Ashland Coke and Burns Harbor Water Issues in NOTE 21 - COMMITMENTS AND CONTINGENCIES to the consolidated financial statements in Part II – Item 8. Financial Statements and Supplementary Data, which information is incorporated herein by reference.

Item 4. Mine Safety Disclosures

We are committed to protecting the occupational health and well-being of each of our employees. Safety is one of our core values, and we strive to ensure that safe production is the first priority for all employees. Our internal objective is to achieve zero injuries and incidents across the Company by focusing on proactively identifying needed prevention activities, establishing standards and evaluating performance to mitigate any potential loss to people, equipment, production and the environment. We have implemented intensive employee training that is geared toward maintaining a high level of awareness and knowledge of safety and health issues in the work environment through the development and coordination of requisite information, skills and attitudes. We believe that through these policies, we have developed an effective safety management system.

Under the Dodd-Frank Act, each operator of a coal or other mine is required to include certain mine safety results within its periodic reports filed with the SEC. As required by the reporting requirements included in §1503(a) of the Dodd-Frank Act and Item 104 of Regulation S-K, the required mine safety results regarding certain mining safety and health matters for each of our mine locations that are covered under the scope of the Dodd-Frank Act are included in Exhibit 95 of Part IV – Item 15.

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

Management's Discussion and Analysis of Financial Condition and Results of Operations is designed to provide a reader of our financial statements with a narrative from the perspective of management on our financial condition, results of operations, liquidity and other factors that may affect our future results. The following discussion should be read in conjunction with the consolidated financial statements and related notes that appear in Part II – Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K.

Overview

The year 2020 represented a transformative period in our Company's 173-year history. During the year, we completed the vertical integration of our legacy iron ore pellet business with the acquisitions of steelmakers AK Steel and ArcelorMittal USA, becoming the largest flat-rolled steel producer in North America. Our new unique, vertically integrated business model provides a competitive advantage over other steelmakers that procure a larger proportion of their steelmaking raw materials from external sources, and allows us to control our production from upstream mining to downstream stamping and tubing.

We believe the Acquisitions give us a leading position in the highly desirable automotive end market, where we supply best-in-class volumes, quality and delivery performance, and give us the most comprehensive flat steel product offering in the industry. Due to the much larger operational footprint we now have, we anticipate synergies of approximately $310 million from asset optimization, economies of scale and streamlining overhead, over half of which has already been set in motion.

We are now focused on maximizing the value of the iron ore pellets we produce from our legacy and recently acquired mines in Michigan and Minnesota. A majority of the pellets we produce is dedicated to internal consumption, and we do not rely on external sources of pellets. As such, our new Steelmaking segment captures effectively all of the production activity in the steelmaking process, which begins at our mines.

In 2020, we also completed construction of and began production at our state-of-the-art direct reduction plant in Toledo, Ohio. This facility produces high-quality HBI, and is the first of its kind in the Great Lakes region. Our HBI provides a high-quality and environmentally friendly alternative to the scrap and imported pig iron that our potential customers currently utilize. We expect to begin selling this product to third parties during the first quarter of 2021 and reach nameplate capacity at our direct reduction plant during the second quarter of 2021.

Along with these notable accomplishments, we have been able to successfully navigate through the COVID-19 pandemic while preserving the health and safety of both our workforce and our Company for the long term. The COVID-19 pandemic caused its fair share of challenges, as disruptions in demand led to lower sales output and necessitated the unplanned idling of certain production facilities. These production outages, along with the lower

45

demand and lower prices that came as a result of the pandemic, generated weaker results during the year than what we would normally expect.

As the demand environment began to recover, our results in the second half of the year improved dramatically and operations at temporarily idled facilities resumed. Now, with steel prices and scrap prices in the U.S. recently reaching all-time highs, we believe our decisive actions and accomplishments during 2020 will allow us to deliver strong financial results and free cash flow in 2021. We also believe our new vertically integrated business model is well-equipped to navigate and succeed through future pricing or demand volatility that is common in our industry.

Despite the ongoing pandemic, we also continued our best practices from both a safety and environmental standpoint. During 2020, our safety TRIR (including contractors) was 0.92 per 200,000 hours worked. On environmental matters, we recently made a commitment to reduce GHG emissions 25% by 2030 from 2017 levels, a higher reduction target than our competitors and a demonstration of the newfound leadership role we plan to take in the domestic steel industry.

Recent Developments

Acquisition of ArcelorMittal USA

On December 9, 2020, pursuant to the terms of the AM USA Transaction Agreement, we purchased ArcelorMittal USA from ArcelorMittal. In connection with the closing of the AM USA Transaction, as contemplated by the terms of the AM USA Transaction Agreement, ArcelorMittal’s former joint venture partner in Kote and Tek exercised its put right pursuant to the terms of the Kote and Tek joint venture agreements. As a result, we purchased all of such joint venture partner’s interests in Kote and Tek. Following the closing of the AM USA Transaction, we own 100% of the interests in Kote and Tek.

The assets of ArcelorMittal USA acquired by us at the closing of the AM USA Transaction include six steelmaking facilities, eight finishing facilities, three cokemaking operations, two iron ore mining and pelletizing operations and one coal mining complex. Refer to NOTE 3 - ACQUISITIONS for additional information.

Financing Transactions

On December 9, 2020, we entered into the ABL Amendment. The ABL Amendment modified the ABL Facility to, among other things, increase the amount of tranche A revolver commitments available thereunder by an additional $1.5 billion and increase certain dollar baskets related to certain negative covenants that apply to the ABL Facility. After giving effect to the ABL Amendment, the aggregate principal amount of tranche A revolver commitments under the ABL Facility is $3.35 billion and the aggregate principal amount of tranche B revolver commitments under the ABL Facility remains at $150 million.

On February 11, 2021, we sold 20 million of our common shares, and the indirect, wholly owned subsidiary of ArcelorMittal to which approximately 78 million common shares were issued as part of the consideration paid by us in connection with the closing of the AM USA Transaction sold 40 million common shares, in each case at a price per share to the underwriter of $16.12, in an underwritten public offering. We also granted the underwriter an option to purchase up to an additional 9 million common shares from us at a price per share to the underwriter of $16.12. The underwriter has until March 10, 2021 to exercise such option, which it may do in full, in part or not at all. We did not receive any proceeds from the sale of the common shares by the selling shareholder in the offering. We intend to use the net proceeds to us from the offering, plus cash on hand, to redeem up to approximately $334 million aggregate principal amount of our outstanding 9.875% 2025 Senior Secured Notes. We intend to use any remaining net proceeds to us following such redemption to reduce borrowings under our ABL Facility.

On February 17, 2021, we issued $500 million aggregate principal amount of 4.625% 2029 Senior Notes and $500 million aggregate principal amount of 4.875% 2031 Senior Notes in an offering that was exempt from the registration requirements of the Securities Act. We intend to use the net proceeds from the notes offering to redeem all of the outstanding 4.875% 2024 Senior Secured Notes and 6.375% 2025 Senior Notes issued by Cleveland-Cliffs Inc. and all of the outstanding 7.625% 2021 AK Senior Notes, 7.50% 2023 AK Senior Notes and 6.375% 2025 AK Senior Notes issued by AK Steel Corporation (n/k/a Cleveland-Cliffs Steel Corporation), and pay fees and expenses in connection with such redemptions, and reduce borrowings under our ABL Facility.

Company Structure

We have updated our segment structure to coincide with our new business model and are organized into four operating segments based on differentiated products, Steelmaking, Tubular, Tooling and Stamping, and European Operations. Our previous Mining and Pelletizing segment is included within Steelmaking as iron ore pellets are a

46

primary raw material for our steel products. We have one reportable segment - Steelmaking. Our other operating segments are classified as our Other Businesses.

COVID-19

In December 2019, COVID-19 surfaced in Wuhan, China, and then spread to other countries, including the United States. In March 2020, the World Health Organization characterized COVID-19 as a pandemic. Efforts to contain the spread of COVID-19 intensified throughout 2020, and many countries, including the United States, took steps to restrict travel, temporarily close businesses and issue quarantine orders. It remains unclear how long and to what degree of severity the economic impact of the COVID-19 pandemic will be felt.

On March 27, 2020, the CARES Act was signed into law. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer-side social security payments, NOL carryback periods, AMT credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. During 2020, the CARES Act provided liquidity relief by enabling us to accelerate the receipt of $60 million of AMT credit refunds in July 2020, defer pension contributions until January 2021, and defer employer social security payments until 2021 and 2022.

We continue to utilize stringent social distancing procedures in our operating facilities, including checking employees’ temperatures and symptoms before entering the workplace each day and deep cleaning our operational facilities. Although we continue to utilize these measures, the outbreak of COVID-19 has heightened the risk that a significant portion of our workforce will suffer illness or otherwise be unable to perform their ordinary work functions.

Although steel and iron ore production are considered “essential” by the states in which we operate, certain of our facilities and construction activities were temporarily idled during the second quarter of 2020 due primarily to temporarily reduced product demand. Most of these temporarily idled facilities were restarted during the second quarter of 2020, and the remaining operations were restarted during the third quarter of 2020. Our Columbus and Monessen facilities acquired through the AM USA Transaction are temporarily idled due to the COVID-19 pandemic.

We cannot predict whether our operations will experience additional disruptions in the future. We may also continue to experience supply chain disruptions or operational issues with our vendors, as our suppliers and contractors face similar challenges related to the COVID-19 pandemic. Because the impact of the COVID-19 pandemic continues to evolve, we cannot currently predict the extent to which our business, results of operations, financial condition or liquidity will ultimately be impacted.

To mitigate the impact of the COVID-19 pandemic, we took a number of steps throughout 2020 to solidify our liquidity position, including issuing $520 million aggregate principal amount of secured debt, adding a $150 million FILO tranche to our ABL Facility, idling several facilities both temporarily and permanently, temporarily deferring our Chief Executive Officer’s compensation by 40%, temporarily deferring salaries by up to 20%, temporarily deferring other salaried employee benefits, and temporarily suspending capital expenditures. Lastly, our Board suspended future dividends, which was a typical cash obligation of approximately $100 million on an annualized basis.

Results of Operations

Overview

For the year ended December 31, 2020, we had a Net loss of $81 million. For the years ended December 31, 2019 and 2018, we had Net income of $293 million and $1,128 million, respectively. Our total revenues, diluted EPS and Adjusted EBITDA were as follows:

    

See "— Results of Operations — Adjusted EBITDA" below for a reconciliation of our Net Income (loss) to Adjusted EBITDA.

Revenues

Revenues from iron products made up 100% of our revenues by product line for the year ended December 31, 2019.

48

During the year ended December 31, 2020, our consolidated Revenues were approximately $5.4 billion, an increase of approximately $3.4 billion, or 169%, compared to 2019. The increase was due to the addition of $4.0 billion in revenues as a result of the Acquisitions, partially offset by a decrease in revenue from iron products of $655 million resulting from lower sales volumes of 6.9 million long tons compared to 2019. The lower sales volumes of iron products in 2020, as compared to 2019, were partially due to the diversion of pellets for internal consumption following the Acquisitions. Overall, we experienced lower customer demand during 2020 as a result of the reduced manufacturing activity caused by the COVID-19 pandemic.

Revenues by Market

The following table represents our consolidated Revenues and percentage of revenues to each of the markets we supply:

Total revenues	$	5,354			$	1,990
1 Includes Realization of deferred revenue of $35 million for the year ended December 31, 2020.

Automotive Market

North American light vehicle production for 2020 declined 20% to approximately 13 million units from the prior year due to the impacts of the COVID-19 pandemic, which forced automotive businesses to shut down from the end of the first quarter of 2020 until near the end of the second quarter of 2020. During the third quarter of 2020, auto makers saw pent-up demand bring sales back to more normal levels as buyers and dealers adapted to new procedures and virtual shopping. Fourth quarter 2020 sales for the automotive industry were more in line with expected sales for the time of year, returning to near pre-COVID-19 levels.

Infrastructure and Manufacturing

Domestic construction activity and the replacement of aging infrastructure directly affects sales of our carbon, stainless and electrical steel products, particularly for GOES. Additionally, during 2020, there were nearly 1.4 million new housing starts in the U.S., an increase of approximately 6% from 2019, and home sales reached nearly 6 million, the highest annual mark since 2006, despite the supply of existing homes reaching all-time lows. This provides a positive indication that domestic GOES customers could continue to experience steady demand consistent with the construction and electrical transformer replacement markets.

Distributors and Converters

Steel distributors and converters typically source from the commodity carbon, stainless and electrical spot markets. The price for domestic HRC, which is an important attribute in the profitability of this end market, averaged $588 per net ton for the year ended December 31, 2020. The price of HRC was negatively impacted by lower demand related to the COVID-19 pandemic, and hit a low point of $438 per net ton on April 30, 2020. However, after the industry recovered and supply-demand dynamics improved, the price rebounded dramatically, improving to a peak of $1,030 per net ton by December 31, 2020.

Steel Producers Market

The steel producers market represents third-party sales to other steel producers, including those who operate blast furnaces and EAFs. It includes sales of raw materials and semi-finished and finished goods, including iron ore pellets, coal, coke, HBI and steel products. Iron ore product revenues declined during 2020, as compared to 2019, partially as a result of the Acquisitions as our iron ore pellet production was consumed internally and the respective intercompany revenue was eliminated in consolidation. Additionally, we experienced lower customer demand during 2020 as a result of the reduced manufacturing activity caused by the impacts of the COVID-19 pandemic.

49

Operating Costs

Cost of goods sold

Cost of goods sold increased by $3,688 million for the year ended December 31, 2020, as compared to the prior year, primarily due to the addition of 4 million net tons of steel shipments resulting from the Acquisitions, partially offset by lower sales volumes of iron products. During 2020, Cost of goods sold was unfavorably impacted by temporary idle-related costs of approximately $225 million, resulting from the impacts of the COVID-19 pandemic.

Selling, general and administrative expenses

As a result of the Acquisitions, our Selling, general and administrative expenses increased by $131 million during the year ended December 31, 2020, as compared to 2019.

Acquisition-related costs

The Acquisition-related costs of $90 million for the year ended December 31, 2020, include severance of $38 million and other various third-party expenses related to the Acquisitions of $52 million. Refer to NOTE 3 - ACQUISITIONS for further information on the Acquisitions.

Miscellaneous – net

Miscellaneous – net increased by $33 million for the year ended December 31, 2020, as compared to the prior year, which was primarily due to an increase in expenses incurred at our Toledo direct reduction plant, primarily related to the hiring and training of employees leading up to the start of production.

Other Income (Expense)

Interest expense, net

Interest expense, net increased by $137 million for the year ended December 31, 2020, as compared to the prior year, primarily due to the incremental debt that we incurred in connection with the AK Steel Merger. The increase was offset partially by an increase in capitalized interest, primarily related to the construction of the Toledo direct reduction plant.

Gain (loss) on extinguishment of debt

The Gain (loss) on extinguishment of debt of $130 million for the year ended December 31, 2020 primarily relates to the repurchase of $748 million aggregate principal amount of our outstanding senior notes of various series using the net proceeds from the issuance of an additional $555 million aggregate principal amount of our 9.875% 2025 Senior Secured Notes on April 24, 2020 and other sources of cash. This compares to a loss on extinguishment of debt of $18 million for the year ended December 31, 2019, primarily related to the redemption of all of our then-outstanding 4.875% 2021 Senior Notes and the repurchase of $600 million aggregate principal amount of our 5.75% 2025 Senior Notes. Refer to NOTE 8 - DEBT AND CREDIT FACILITIES for further details.

Other non-operating income

The increase of $54 million in Other non-operating income primarily relates to an increase in net periodic benefit credits other than service cost component predominantly due to the expected return on assets resulting from the Acquisitions and increased asset values for the plans held in 2019. Refer to NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further details.

Income Taxes

Our effective tax rate is affected by permanent items, primarily depletion. It also is affected by discrete items that may occur in any given period, but are not consistent from period to period. The following represents a summary of our tax provision and corresponding effective rates:

Provision for income tax expense (benefit) and effective income tax rate including discrete items	$	(111)	57	%	$	18	6	%

The increase in income tax benefit in 2020, as compared to the prior year, is directly related to the increase in the pre-tax book loss year-over-year. The Luxembourg legal entity reduction relates to initiatives resulting in the dissolution of entities and settlement of related financial instruments in the year ended December 31, 2019. The 2019 NOL deferred tax asset reduction resulted in tax expense of $846 million, which was fully offset by a decrease in the valuation allowance.

See NOTE 12 - INCOME TAXES for further information.

Adjusted EBITDA

We evaluate performance based on Adjusted EBITDA, which is a non-GAAP measure. This measure is used by management, investors, lenders and other external users of our financial statements to assess our operating performance and to compare operating performance to other companies in the steel industry, although it is not necessarily comparable to similarly titled measures used by other companies. In addition, management believes Adjusted EBITDA is a useful measure to assess the earnings power of the business without the impact of capital structure and can be used to assess our ability to service debt and fund future capital expenditures in the business.

The year ended December 31, 2020 results were unfavorably impacted by decreased customer demand resulting from the impacts of the COVID-19 pandemic. As a result of the COVID-19 pandemic, we incurred temporary idle-related costs resulting from production curtailments, excluding idle depreciation, depletion and amortization expense, of approximately $214 million during 2020.

Adjusted EBITDA from Corporate and eliminations primarily relates to Selling, general and administrative expenses at our Corporate headquarters.

Operating Results

Despite the downward pressures on markets as a result of the COVID-19 pandemic during 2020, the operating results during the second half of the year showed significant signs of improvement heading into 2021, as we have seen pricing for HRC continue to rise and sales volumes begin to return to normal. Steelmaking revenues increased by $2,975 million compared to 2019, due to the addition of sales following the Acquisitions. This increase was partially offset by a decrease in revenue from iron products of $655 million resulting from lower sales volumes of 7 million long tons compared to 2019, partially due to the diversion of pellets for internal consumption following the Acquisitions, as well as lower overall demand from customers as a result of the impacts of the COVID-19 pandemic.

Cost of goods sold increased $3,335 million during 2020, compared to 2019, predominantly due to additional sales resulting from the Acquisitions; however, this increase was also unfavorably impacted by idle-related costs of approximately $225 million, driven by the temporary idling of facilities in response to lower customer demand due to the COVID-19 pandemic.

As a result, Adjusted EBITDA was $433 million for the year ended December 31, 2020, compared to $636 million for the prior year. Refer to "— Results of Operations" above for additional information.

Production

During 2020, we produced 4 million net tons of raw steel, 17 million long tons of iron ore pellets and 1 million net tons of coke. During 2020, certain of our operations were temporarily idled in response to the COVID-19 pandemic, with most restarting and resuming production in the second quarter of 2020 and the remainder in the third quarter of 2020. Dearborn Works' hot strip mill, anneal and temper operations and AK Coal remain permanently idled as part of the permanent cost reduction efforts. Our Columbus and Monessen facilities acquired through the AM USA Transaction are temporarily idled due to impacts of the COVID-19 pandemic. During 2019, we produced 20 million long tons of iron ore pellets.

Liquidity, Cash Flows and Capital Resources

Our primary sources of liquidity are Cash and cash equivalents and cash generated from our operations, availability under the ABL Facility and other financing activities. Our capital allocation decision-making process is focused on preserving healthy liquidity levels, while maintaining the strength of our balance sheet and creating financial flexibility to manage through the inherent cyclical demand for our products and volatility in commodity prices. We are focused on maximizing the cash generation of our operations, reducing debt, and aligning capital investments with our strategic priorities and the requirements of our business plan, including regulatory and permission-to-operate related projects.

Since the onset of the COVID-19 pandemic in the U.S., our primary focus has been on maintaining adequate levels of liquidity to manage through a potentially prolonged economic downturn. In alignment with this, we made several operational adjustments, including facility closures, idles and extended maintenance outages. Along with the cost savings achieved through these operational adjustments, during 2020, we reduced planned capital expenditures for the year, reduced overhead costs and suspended our quarterly dividend payment. Additionally, on April 17, 2020 and April 24, 2020, we issued $400 million aggregate principal amount and an additional $555 million aggregate principal amount, respectively, of 9.875% 2025 Senior Secured Notes to further bolster our liquidity position and pay-down existing debt. We also issued an additional $120 million aggregate principal amount of 6.75% 2026 Senior Secured Notes on June 19, 2020, the net proceeds of which we used to finance construction of our Toledo direct reduction plant. Prior to such use, the net proceeds were used to temporarily reduce the outstanding borrowings under our ABL Facility. We believe these measures have helped us to maintain healthy liquidity levels during the COVID-19 pandemic.

Now that business conditions have improved and we expect to generate healthy free cash flow during 2021, we believe we have the ability to lower our long-term debt balance. Our stated initial target will be to reduce total debt to less than three times our annual Adjusted EBITDA. We also look at the composition of our debt, as well, as we are interested in both extending our maturity profile and increasing our ratio of unsecured debt to secured debt. These actions will better prepare us to navigate more easily through potentially volatile industry conditions in the future. In furtherance of these goals, we consummated certain financing transactions in February 2021.

On February 11, 2021, we sold 20 million common shares and the indirect, wholly owned subsidiary of ArcelorMittal to which approximately 78 million common shares were issued as part of the consideration paid by us in connection with the closing of the AM USA Transaction sold 40 million common shares, in each case at a price per share to the underwriter of $16.12, in an underwritten public offering. We also granted the underwriter an option to purchase up to an additional 9 million common shares from us at a price per share to the underwriter of $16.12. The underwriter has until March 10, 2021 to exercise such option, which it may do in full, in part or not at all. We did not receive any proceeds from the sale of the common shares by the selling shareholder in the offering. We intend to use the net proceeds to us from the offering, plus cash on hand, to redeem up to approximately $334 million aggregate principal amount of our outstanding 9.875% 2025 Senior Secured Notes. We intend to use any remaining net proceeds to us following such redemption to reduce borrowings under our ABL Facility.

On February 17, 2021, we issued $500 million aggregate principal amount of 4.625% 2029 Senior Notes and $500 million aggregate principal amount of 4.875% 2031 Senior Notes in an offering that was exempt from the registration requirements of the Securities Act. We intend to use the net proceeds from the notes offering to redeem all of the outstanding 4.875% 2024 Senior Secured Notes and 6.375% 2025 Senior Notes issued by Cleveland-Cliffs Inc. and all of the outstanding 7.625% 2021 AK Senior Notes, 7.50% 2023 AK Senior Notes and 6.375% 2025 AK Senior Notes issued by AK Steel Corporation (n/k/a Cleveland-Cliffs Steel Corporation), and pay fees and expenses in connection with such redemptions, and reduce borrowings under our ABL Facility.

In connection with the underwritten public offering, we provided notice to redeem $322.4 million aggregate principal amount of our 9.875% 2025 Senior Secured Notes on March 11, 2021. In connection with the notes offering, we provided notice to redeem all of the outstanding 4.875% 2024 Senior Secured Notes, 6.375% 2025 Senior Notes,

54

7.625% 2021 AK Senior Notes, 7.50% 2023 AK Senior Notes and 6.375% 2025 AK Senior Notes on March 12, 2021. Refer to NOTE 22 – SUBSEQUENT EVENTS for more information regarding February 2021 financing transactions.

The application of the net proceeds to us from the February 2021 financing transactions will shift our debt horizon, by providing a four-year window in which none of our long-term notes are due, clearing the way for us to fully focus on operational integration.

Based on our outlook for the next 12 months, which is subject to continued changing demand from customers and volatility in domestic steel prices, we expect to have ample liquidity through cash generated from operations and availability under our ABL Facility sufficient to meet the needs of our operations and service our debt obligations.

The following discussion summarizes the significant items impacting our cash flows during 2020 and comparative years as well as expected impacts to our future cash flows over the next 12 months. Refer to the Statements of Consolidated Cash Flows for additional information.

Operating Activities

Net cash used by operating activities was $261 million for the year ended December 31, 2020, compared to net cash provided by operating activities of $563 million for the year ended December 31, 2019. The change in cash used by operating activities during 2020, compared to cash provided by operating activities in 2019, was due primarily to the slowing economy in connection with the COVID-19 pandemic, resulting in reduced customer demand and the need to temporarily idle many of our operations, which had an adverse effect on our operating results. Our working capital was negatively impacted as a result of ArcelorMittal USA's accounts receivable factoring arrangement that was in place prior to the AM USA Transaction. This negatively impacted working capital by $315 million for the year ended December 31, 2020 and is expected to impact the first quarter of 2021 by approximately $260 million.

Our U.S. Cash and cash equivalents balance at December 31, 2020 was $90 million, or 84% of our consolidated Cash and cash equivalents balance, excluding cash related to our consolidated VIE of $5 million. Additionally, we had a cash balance at December 31, 2020 of $4 million classified as part of Other current assets in the Statements of Consolidated Financial Position related to our discontinued operations.

Investing Activities

Net cash used by investing activities was $2,042 million and $644 million for the years ended December 31, 2020 and 2019, respectively. During the year ended December 31, 2020, we had net cash outflows of $658 million related to the AM USA Transaction, net of cash acquired. Additionally, during the year ended December 31, 2020, we had net cash outflows of $869 million related to the AK Steel Merger, net of cash acquired, which included $590 million used to repay the former AK Steel Corporation revolving credit facility and $324 million used to purchase outstanding 7.50% 2023 AK Senior Notes. Refer to NOTE 3 - ACQUISITIONS for additional details on the Acquisitions.

Additionally, we had capital expenditures, including capitalized interest, of $525 million and $656 million for the years ended December 31, 2020 and 2019, respectively. We had cash outflows, including deposits and capitalized interest, for the development of the Toledo direct reduction plant of $348 million and $544 million for the years ended December 31, 2020 and 2019, respectively. During the year ended December 31, 2019, we also had cash outflows, including deposits and capitalized interest, of $43 million on the upgrades at Northshore. Additionally, we spent $177 million and $69 million on sustaining capital expenditures during 2020 and 2019, respectively. Sustaining capital expenditures include capital expenditures related to infrastructure, mobile equipment, fixed equipment, product quality, environment, health and safety.

During 2020, in response to the COVID-19 pandemic, we temporarily limited our cash used for capital expenditures to critical sustaining capital, but have now resumed growth capital spending. During the fourth quarter of 2020, we completed construction of our Toledo direct reduction plant. We anticipate total cash used for capital expenditures during the next 12 months to be between $600 million and $650 million.

Financing Activities

Net cash provided by financing activities was $2,059 million for the year ended December 31, 2020, compared to net cash used by financing activities of $394 million for the year ended December 31, 2019. Cash provided by financing activities for the year ended December 31, 2020 primarily related to the issuances in separate offerings consummated on March 13, 2020 and June 19, 2020 of $845 million combined aggregate principal amount of 6.75% 2026 Senior Secured Notes, the issuances in separate offerings consummated on April 17, 2020 and April 24, 2020 of $955 million combined aggregate principal amount of 9.875% 2025 Senior Secured Notes and borrowings

55

of $2,060 million under the ABL Facility. The net proceeds from the initial issuance of $725 million aggregate principal amount of the 6.75% 2026 Senior Secured Notes on March 13, 2020, along with cash on hand, were used to purchase $373 million aggregate principal amount of 7.625% 2021 AK Senior Notes and $367 million aggregate principal amount of 7.50% 2023 AK Senior Notes, in each case issued by AK Steel Corporation (n/k/a Cleveland-Cliffs Steel Corporation), that we accepted for purchase pursuant to our tender offers for any and all such notes then-outstanding in connection with the AK Steel Merger and to pay for the $44 million of debt issuance costs in the first quarter of 2020. The net proceeds from the additional issuance of $555 million aggregate principal amount of the 9.875% 2025 Senior Secured Notes on April 24, 2020 were used to repurchase $736 million aggregate principal amount of our outstanding senior notes of various series in private exchanges exempt from the registration requirements of the Securities Act. The net proceeds from the additional issuance of $120 million aggregate principal amount of 6.75% 2026 Senior Secured Notes on June 19, 2020 were used to finance construction of our Toledo direct reduction plant. Prior to such use, the net proceeds were used to temporarily reduce the outstanding borrowings under our ABL Facility. Additionally, during the year ended December 31, 2020, we repaid $550 million under the ABL Facility.

Net cash used by financing activities during 2019 primarily related to the repurchase of 24 million common shares for $253 million in the aggregate under the $300 million share repurchase program, which was active until December 31, 2019. Additionally, we issued $750 million aggregate principal amount of 5.875% 2027 Senior Notes, which provided net proceeds of approximately $714 million. The net proceeds from the notes offering, along with cash on hand, were used to redeem in full all of our then-outstanding 4.875% 2021 Senior Notes and to purchase $600 million aggregate principal amount of our outstanding 5.75% 2025 Senior Notes pursuant to a tender offer. In total, during 2019, we purchased $724 million aggregate principal amount of senior notes for $729 million in cash.

Additional uses of cash from financing activities during 2019 included payments of regular quarterly cash dividends and a special cash dividend on our common shares of $72 million and a cash payment of $44 million related to the third and final annual installment of the distribution of Empire partnership equity.

We have temporarily suspended future dividend distributions as a result of impacts of the COVID-19 pandemic in order to preserve cash during this time of economic uncertainty. We anticipate future uses of cash and cash provided by financing activities during the next 12 months to include opportunistic debt transactions as part of our liability management strategy, similar to the transactions that occurred during 2020 and February 2021, in addition to providing supplemental financing to meet cash requirements for business improvement opportunities.

The discussion of our Liquidity, Cash Flows and Capital Resources results for 2019 compared to 2018 can be found in Part II, Item 7., "Management's Discussion and Analysis of Financial Condition and Results of Operations", in our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 20, 2020.

Capital Resources

We expect to fund our business obligations from available cash, current and future operations and existing and future borrowing arrangements. We also may pursue other funding strategies in the capital markets to strengthen our liquidity, extend debt maturities and/or fund strategic initiatives. The following represents a summary of key liquidity measures:

	(In Millions)
	December 31, 2020
Cash and cash equivalents	$	112
Cash and cash equivalents from discontinued operations, included within Other current assets	4
Less: Cash and cash equivalents from VIE's	(5)
Total cash and cash equivalents	$	111
Available borrowing base on ABL Facility1	$	3,500
Borrowings	(1,510)
Letter of credit obligations	(247)
Borrowing capacity available	$	1,743
1 As of December 31, 2020, the ABL Facility had a maximum borrowing base of $3.5 billion, determined by applying customary advance rates to eligible accounts receivable, inventory and certain mobile equipment.

Our primary sources of funding are cash and cash equivalents, which totaled $111 million as of December 31, 2020, cash generated by our business, availability under the ABL Facility and other financing activities. Cash and cash equivalents include cash on hand and on deposit. The combination of cash and availability under the ABL Facility gives us $1.9 billion in liquidity entering the first quarter of 2021, which is expected to be adequate to fund operations, letter of credit obligations, sustaining and expansion capital expenditures and other cash commitments for at least the next 12 months.

As of February 24, 2021, we had total liquidity of approximately $2.6 billion, consisting of approximately $200 million in cash and approximately $2.4 billion of availability under its ABL credit facility, of which approximately $850 million is expected to be used to redeem the senior notes for which notice of redemption was provided in connection with the offerings consummated in February 2021.

As of December 31, 2020, we were in compliance with the ABL Facility liquidity requirements and, therefore, the springing financial covenant requiring a minimum Fixed Charge Coverage Ratio of 1.0 to 1.0 was not applicable. We believe that the cash on hand and the ABL Facility provide us sufficient liquidity to support our operating, investing and financing activities. We have the capability to issue additional unsecured notes and, subject to the limitations set forth in our existing senior notes indentures, additional secured debt, if we elect to access the debt capital markets. However, our ability to issue additional notes could be limited by market conditions.

We intend from time to time to seek to retire or purchase our outstanding senior notes with cash on hand, borrowings from existing credit sources or new debt financings and/or exchanges for debt or equity securities, in open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors, and the amounts involved may be material.

Off-Balance Sheet Arrangements

In the normal course of business, we are a party to certain arrangements that are not reflected on our Statements of Consolidated Financial Position. These arrangements include minimum "take or pay" purchase commitments, such as minimum electric power demand charges, minimum coal, diesel and natural gas purchase commitments, minimum railroad transportation commitments and minimum port facility usage commitments; and financial instruments with off-balance sheet risk, such as bank letters of credit and bank guarantees.

Market Risks

We are subject to a variety of risks, including those caused by changes in commodity prices and interest rates. We have established policies and procedures to manage such risks; however, certain risks are beyond our control.

Pricing Risks

In the ordinary course of business, we are exposed to market risk and price fluctuations related to the sale of our products, which are impacted primarily by market prices for HRC, and the purchase of energy and raw materials used in our operations, which are impacted by market prices for electricity, natural gas, ferrous and stainless steel scrap, chrome, coal, coke, nickel and zinc. Our strategy to address market risk has generally been to obtain competitive prices for our products and services and allow operating results to reflect market price movements dictated by supply and demand; however, we make forward physical purchases and enter into hedge contracts to manage exposure to price risk related to the purchases of certain raw materials and energy used in the production process.

Our financial results can vary for our operations as a result of fluctuations in market prices. We attempt to mitigate these risks by aligning fixed and variable components in our customer pricing contracts, supplier purchasing agreements and derivative financial instruments.

Some customer contracts have fixed-pricing terms, which increase our exposure to fluctuations in raw material and energy costs. To reduce our exposure, we enter into annual, fixed-price agreements for certain raw materials. Some of our existing multi-year raw material supply agreements have required minimum purchase quantities. Under adverse economic conditions, those minimums may exceed our needs. Absent exceptions for force

60

majeure and other circumstances affecting the legal enforceability of the agreements, these minimum purchase requirements may compel us to purchase quantities of raw materials that could significantly exceed our anticipated needs or pay damages to the supplier for shortfalls. In these circumstances, we would attempt to negotiate agreements for new purchase quantities. There is a risk, however, that we would not be successful in reducing purchase quantities, either through negotiation or litigation. If that occurred, we would likely be required to purchase more of a particular raw material in a particular year than we need, negatively affecting our results of operations and cash flows.

Certain of our customer contracts include variable-pricing mechanisms that adjust selling prices in response to changes in the costs of certain raw materials and energy, while other of our customer contracts exclude such mechanisms. We may enter multi-year purchase agreements for certain raw materials with similar variable-price mechanisms, allowing us to achieve natural hedges between the customer contracts and supplier purchase agreements. Therefore, in some cases, price fluctuations for energy (particularly natural gas and electricity), raw materials (such as scrap, chrome, zinc and nickel) or other commodities may be, in part, passed on to customers rather than absorbed solely by us. There is a risk, however, that the variable-price mechanisms in the sales contracts may not necessarily change in tandem with the variable-price mechanisms in our purchase agreements, negatively affecting our results of operations and cash flows.

Our strategy to address volatile natural gas rates and electricity rates includes improving efficiency in energy usage, identifying alternative providers and utilizing the lowest cost alternative fuels. If we are unable to align fixed and variable components between customer contracts and supplier purchase agreements, we use cash-settled commodity price swaps and options to hedge the market risk associated with the purchase of certain of our raw materials and energy requirements. Additionally, we routinely use these derivative instruments to hedge a portion of our natural gas, electricity and zinc requirements. Our hedging strategy is designed to protect us from excessive pricing volatility. However, since we do not typically hedge 100% of our exposure, abnormal price increases in any of these commodity markets might still negatively affect operating costs. The following table summarizes the impact of a 10% and 25% change in market price from the December 31, 2020 estimated price on our derivative instruments, thereby impacting our pre-tax income by the same amount.

	Positive or Negative Effect on Pre-tax Income
Commodity Derivative	10% Increase or Decrease		25% Increase or Decrease
Natural gas	$	28	$	69
Electricity	2		4
Zinc	1		2

Valuation of Goodwill and Other Long-Lived Assets

We assign goodwill arising from acquired companies to the reporting units that are expected to benefit from the synergies of the acquisition. Goodwill is tested on a qualitative basis for impairment at the reporting unit level on an annual basis (October 1) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition or sale or disposition of a significant portion of a reporting unit. As necessary, should our qualitative test indicate that it is more likely than not that the fair value of a reporting unit is less than its carry amount, we perform a quantitative test to determine the amount of impairment, if any, to the carrying value of the reporting unit and its associated goodwill.

Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units and if a quantitative assessment is deemed necessary in determination of the fair value of each reporting unit. The fair value of each reporting unit is estimated using a discounted cash flow methodology, which considers forecasted cash flows discounted at an estimated weighted average cost of capital. Assessing the recoverability of our goodwill requires significant assumptions regarding the estimated future cash flows and other factors to determine the fair value of a reporting unit, including, among other things, estimates related to forecasts of future revenues, expected Adjusted EBITDA, expected capital expenditures and working capital requirements, which are based upon our long-range plan estimates. The assumptions used to calculate the fair value of a reporting unit may change from year to year based on operating results, market conditions and other factors. Changes in these assumptions could materially affect the determination of fair value for each reporting unit.

61

Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the assets may not be recoverable. Such indicators may include: a significant decline in expected future cash flows; a sustained, significant decline in market pricing; a significant adverse change in legal or environmental factors or in the business climate; changes in estimates of our recoverable reserves; and unanticipated competition. Any adverse change in these factors could have a significant impact on the recoverability of our long-lived assets and could have a material impact on our consolidated statements of operations and statement of financial position.

A comparison of each asset group's carrying value to the estimated undiscounted net future cash flows expected to result from the use of the assets, including cost of disposition, is used to determine if an asset is recoverable. Projected future cash flows reflect management's best estimate of economic and market conditions over the projected period, including growth rates in revenues and costs, and estimates of future expected changes in operating margins and capital expenditures. If the carrying value of the asset group is higher than its undiscounted net future cash flows, the asset group is measured at fair value and the difference is recorded as a reduction to the long-lived assets. We estimate fair value using a market approach, an income approach or a cost approach. While we concluded that an event triggering the need for an impairment assessment did not occur during the year ended December 31, 2020, a prolonged COVID-19 pandemic could impact the results of operations due to changes to assumptions that would indicate that the carrying value of our asset groups may not be recoverable.

Interest Rate Risk

Interest payable on our senior notes is at fixed rates. Interest payable under our ABL Facility is at a variable rate based upon the applicable base rate plus the applicable base rate margin depending on the excess availability. As of December 31, 2020, we had $1,510 million outstanding under the ABL Facility. An increase in prevailing interest rates would increase interest expense and interest paid for any outstanding borrowings under the ABL Facility. For example, a 100 basis point change to interest rates under the ABL Facility at the December 31, 2020 borrowing level would result in a change of $15 million to interest expense on an annual basis.

Supply Concentration Risks

Many of our operations and mines rely on one source for each of electric power and natural gas. A significant interruption or change in service or rates from our energy suppliers could materially impact our production costs, margins and profitability.

Recently Issued Accounting Pronouncements

Refer to NOTE 1 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES of the consolidated financial statements for a description of recent accounting pronouncements, including the respective dates of adoption and effects on results of operations and financial condition.

Critical Accounting Estimates

Management's discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. Preparation of financial statements requires management to make assumptions, estimates and judgments that affect the reported amounts of assets, liabilities, revenues, costs and expenses, and the related disclosures of contingencies. Management bases its estimates on various assumptions and historical experience, which are believed to be reasonable; however, due to the inherent nature of estimates, actual results may differ significantly due to changed conditions or assumptions. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our financial statements are fairly presented in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material. Management believes that the following critical accounting estimates and judgments have a significant impact on our financial statements.

Business Combinations

Assets acquired and liabilities assumed in a business combination are recognized and measured based on their estimated fair values at the acquisition date, while the acquisition-related costs are expensed as incurred. Any excess of the purchase consideration when compared to the fair value of the net tangible and intangible assets acquired, if any, is recorded as goodwill. We engaged independent valuation specialists to assist with the determination of the fair value of assets acquired, liabilities assumed, noncontrolling interest, and goodwill, for the Acquisitions. If the initial accounting for the business combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded. Subsequent to the acquisition date, and not later than one

62

year from the acquisition date, we will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the date of the acquisition. Any adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period the adjustment arises.

Valuation of Goodwill and Other Long-Lived Assets

The valuation of goodwill and other long-lived assets includes various assumptions and are considered critical accounting estimates. Refer to "–Market Risks" above for additional information.

Mineral Reserves

We regularly evaluate our mineral reserves and update them as required in accordance with SEC Industry Guide 7. We perform an in-depth evaluation of our mineral reserve estimates by mine on a periodic basis, in addition to routine annual assessments. The determination of mineral reserves requires us, with the support of our third-party experts, to make significant estimates and assumptions related to key inputs including (1) the determination of the size and scope of the iron ore body through technical modeling, (2) the estimates of future iron ore prices, production costs and capital expenditures, and (3) management’s mine plan for the proven and probable mineral reserves. The significant estimates and assumptions could be affected by future industry conditions, geological conditions and ongoing mine planning. Additional capital and development expenditures may be required to maintain effective production capacity. Generally, as mining operations progress, haul distances increase. Alternatively, changes in economic conditions or the expected quality of mineral reserves could decrease capacity of mineral reserves. Technological progress could alleviate such factors or increase capacity of mineral reserves.

We use our mineral reserve estimates, combined with our estimated annual production levels, to determine the mine closure dates utilized in recording the fair value liability for asset retirement obligations for our active operating mines. Refer to NOTE 14 - ASSET RETIREMENT OBLIGATIONS, for further information. Since the liability represents the present value of the expected future obligation, a significant change in mineral reserves or mine lives could have a substantial effect on the recorded obligation. We also utilize mineral reserves for evaluating potential impairments of mine asset groups as they are indicative of future cash flows and in determining maximum useful lives utilized to calculate depreciation, depletion and amortization of long-lived mine assets and in determining the estimated fair value of mineral reserves established through the purchase price allocation in a business combination. The consolidated asset retirement obligation balance was $342 million as of December 31, 2020, of which $83 million related to active iron ore mine operations. The total asset balance associated with our Steelmaking reportable segment was $15,849 million as of December 31, 2020, of which $1,661 million related to long-lived assets associated with our combined iron ore mine asset groups, and is inclusive of $235 million related to iron ore mineral reserves acquired through the AM USA Transaction. Depreciation, depletion and amortization expense for the our combined iron ore mine asset groups was $78 million for the year ended December 31, 2020. Increases or decreases in mineral reserves or mine lives could significantly affect these items.

Asset Retirement Obligations

The accrued closure obligation is predominantly related to our indefinitely idled and closed iron ore mining operations and provides for contractual and legal obligations associated with the eventual closure of those operations. We perform an in-depth evaluation of the liability every three years in addition to our routine annual assessments. In 2020, we employed third-party specialists to assist in the evaluation. Our obligations are determined based on detailed estimates adjusted for factors that a market participant would consider (e.g., inflation, overhead and profit), which are escalated at an assumed rate of inflation to the estimated closure dates, and then discounted using the current credit-adjusted risk-free interest rate. The estimate also incorporates incremental increases in the closure cost estimates and changes in estimates of mine lives for our active mine sites. The closure date for each of our active mine sites is determined based on the exhaustion date of the remaining iron ore reserves, which is dependent on our estimate of mineral reserves. The estimated obligations for our active mine sites are particularly sensitive to the impact of changes in mine lives given the difference between the inflation and discount rates. The closure dates for a majority of our steelmaking facilities are indefinite, and as such, the asset retirement obligations are recorded at present values using estimated ranges of the economic lives of the underlying assets. Changes in the base estimates of legal and contractual closure costs due to changes in legal or contractual requirements, available technology, inflation, overhead or profit rates also could have a significant impact on the recorded obligations. Refer to NOTE 14 - ASSET RETIREMENT OBLIGATIONS, for further information.

63

Environmental Remediation Costs

We have a formal policy for environmental protection and remediation. Our obligations for known environmental matters at active and closed operations have been recognized based on estimates of the cost of investigation and remediation at each facility. If the obligation can only be estimated as a range of possible amounts, with no specific amount being more likely, the minimum of the range is accrued. Management reviews its environmental remediation sites quarterly to determine if additional cost adjustments or disclosures are required. The characteristics of environmental remediation obligations, where information concerning the nature and extent of clean-up activities is not immediately available and which are subject to changes in regulatory requirements, result in a significant risk of increase to the obligations as they mature. Expected future expenditures are not discounted to present value unless the amount and timing of the cash disbursements can be reasonably estimated.

Income Taxes

Our income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management's best assessment of estimated future taxes to be paid. We are subject to income taxes in the U.S. and various foreign jurisdictions. Significant judgments and estimates are required in determining the consolidated income tax expense.

Deferred income taxes arise from temporary differences between tax and financial statement recognition of revenue and expense. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In projecting future taxable income, we begin with historical results adjusted for the results of discontinued operations and changes in accounting policies and incorporate assumptions including the amount of future state, federal and foreign pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses.

At December 31, 2020 and 2019, we had a valuation allowance of $836 million and $441 million, respectively, against our deferred tax assets. Of these amounts, $439 million and $44 million relate to the U.S. deferred tax assets at December 31, 2020 and 2019, respectively, and $397 million and $397 million relate to foreign deferred tax assets, respectively.

At December 31, 2018, we determined that it was appropriate to release all of the valuation allowance related to U.S. federal deferred tax assets as it is more likely than not that the entire deferred tax asset will be realized before the end of the carryforward period. See NOTE 12 - INCOME TAXES for further information and considerations related to the release.

Our losses in Luxembourg in recent periods represent sufficient negative evidence to require a full valuation allowance against the deferred tax assets in that jurisdiction. We intend to maintain a valuation allowance against the deferred tax assets related to these operating losses, unless and until sufficient positive evidence exists to support the realization of such assets.

Changes in tax laws and rates also could affect recorded deferred tax assets and liabilities in the future. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in various jurisdictions across our global operations. The ultimate impact of the U.S. income tax reform legislation may differ from our current estimates due to changes in the interpretations and assumptions made as well as additional regulatory guidance that may be issued.

Accounting for uncertainty in income taxes recognized in the financial statements requires that a tax benefit from an uncertain tax position be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on technical merits.

We recognize tax liabilities in accordance with ASC 740, Income Taxes, and we adjust these liabilities when our judgment changes because of evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in payment that is materially different from our current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which they are determined. Refer to NOTE 12 - INCOME TAXES, for further information.

Employee Retirement Benefit Obligations

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits, to most employees in North America as part of a total compensation and benefits program.

The following is a summary of our U.S. defined benefit pension and OPEB funding and expense:

	Pension				OPEB
	Funding		Expense (Benefit)		Funding		Expense (Benefit)
2018	$	28	$	13	$	4	$	(6)
2019	16		22		4		(2)
2020	50		(31)		25		8
2021 (Estimated)1	202		(168)		144		86
1 The estimated 2021 pension funding includes $118 million, which was deferred as a result of the CARES Act.

Assumptions used in determining the benefit obligations and the value of plan assets for defined benefit pension plans and OPEB plans, primarily consisting of retiree healthcare benefits, that we offer are evaluated periodically by management. Critical assumptions, such as the discount rate used to measure the benefit obligations, the expected long-term rate of return on plan assets, the medical care cost trend, and the rate of compensation increase are reviewed annually.

The following represents weighted-average assumptions used to determine benefit obligations and net benefit costs:

	Pension				Other Benefits
	December 31,				December 31,
	2020		2019		2020		2019
Discount rate	2.34	%	3.27	%	2.71	%	2.71	%
Compensation rate increase	2.56		2.53		3.00		3.00
Expected return on plan assets	7.69		8.25		6.82		7.00

The following represents assumed weighted-average health care cost trend rates:

	December 31,
	2020		2019
Health care cost trend rate assumed for next year	6.05	%	6.50	%
Ultimate health care cost trend rate	4.59		5.00
Year that the ultimate rate is reached	2031		2026

The discount rates used to measure plan liabilities as of the December 31 measurement date are determined individually for each plan. The discount rates are determined by matching the projected cash flows used to determine the plan liabilities to a projected yield curve of high-quality corporate bonds available at the measurement date. Discount rates for expense are calculated using the granular approach for each plan.

Depending on the plan, we use either company-specific base mortality tables or tables issued by the Society of Actuaries. We adopted the Pri-2012 mortality tables from the Society of Actuaries in 2019. On December 31, 2020, the assumed mortality improvement projection was updated from generational scale MP-2019 to generational scale MP-2020 for the Pri-2012 mortality tables.

65

Following are sensitivities of potential further changes in these key assumptions on the estimated 2021 pension and OPEB expense and the pension and OPEB obligations as of December 31, 2020:

	(In Millions)
	Increase (Decrease) in Expense				Increase in Benefit Obligation
	Pension		OPEB		Pension		OPEB
Decrease discount rate 0.25%	$	(4)	$	(2)	$	164	$	131
Decrease return on assets 1.00%	53		8		N/A		N/A

Changes in actuarial assumptions, including discount rates, employee retirement rates, mortality, compensation levels, plan asset investment performance and healthcare costs, are determined based on analyses of actual and expected factors. Changes in actuarial assumptions and/or investment performance of plan assets may have a significant impact on our financial condition due to the magnitude of our retirement obligations.

Refer to NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Notes to Consolidated Financial Statements

Cleveland-Cliffs Inc. and Subsidiaries

NOTE 1 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Business, Consolidation and Presentation

Nature of Business

Cliffs is the largest flat-rolled steel producer in North America. Founded in 1847 as a mine operator, we are also the largest producer of iron ore pellets in North America. In 2020, we acquired two major steelmakers, AK Steel and ArcelorMittal USA, vertically integrating our legacy iron ore business. Our fully-integrated portfolio includes custom-made pellets and HBI; flat-rolled carbon steel, stainless, electrical, plate, tinplate and long steel products; as well as carbon and stainless steel tubing, hot and cold stamping and tooling. Headquartered in Cleveland, Ohio, we employ approximately 25,000 people across our mining, steel and downstream manufacturing operations in the United States and Canada.

Unless otherwise noted, discussion of our business and results of operations in this Annual Report on Form 10-K refers to our continuing operations.

Acquisition of AK Steel

On March 13, 2020, we consummated the AK Steel Merger, pursuant to which, upon the terms and subject to the conditions set forth in the AK Steel Merger Agreement, Merger Sub was merged with and into AK Steel, with AK Steel surviving the AK Steel Merger as a wholly owned subsidiary of Cleveland-Cliffs Inc. Refer to NOTE 3 - ACQUISITIONS for further information.

AK Steel is a North American producer of flat-rolled carbon, stainless and electrical steel products, primarily for the automotive, infrastructure and manufacturing markets. These operations consist primarily of seven steelmaking and finishing plants, two cokemaking operations, three tube manufacturing plants and ten tooling and stamping operations. The acquisition of AK Steel transformed us into a vertically integrated producer of value-added iron ore and steel products.

Acquisition of ArcelorMittal USA

On December 9, 2020, pursuant to the terms of the AM USA Transaction Agreement, we purchased ArcelorMittal USA from ArcelorMittal. In connection with the closing of the AM USA Transaction, as contemplated by the terms of the AM USA Transaction Agreement, ArcelorMittal’s former joint venture partner in Kote and Tek exercised its put right pursuant to the terms of the Kote and Tek joint venture agreements. As a result, we purchased all of such joint venture partner’s interests in Kote and Tek. Following the closing of the AM USA Transaction, we own 100% of the interests in Kote and Tek.

The assets of ArcelorMittal USA we acquired at the closing of the AM USA Transaction include six steelmaking facilities, eight finishing facilities, three cokemaking operations, two iron ore mining and pelletizing operations and one coal mining complex.

Refer to NOTE 3 - ACQUISITIONS for further information.

Business Operations

We are vertically integrated from the mining of iron ore and coal; to production of metallics and coke; through iron making, steelmaking, rolling and finishing; and to downstream tubular components, stamping and tooling. We have the unique advantage as a steel producer of being fully or partially self-sufficient with our production of raw materials for steel manufacturing, which includes iron ore pellets, HBI and coking coal.

We have updated our segment structure to coincide with our new business model and are organized into four operating segments based on differentiated products, Steelmaking, Tubular, Tooling and Stamping, and European Operations. Through the third quarter ended September 30, 2020, we had operated through two reportable segments – the Steel and Manufacturing segment and the Mining and Pelletizing segment. However, given the recent

74

transformation of the business, beginning with our financial statements as of and for the year ended December 31, 2020, we primarily operate through one reportable segment – the Steelmaking segment.

COVID-19

In response to the COVID-19 pandemic, we made various operational changes to adjust to the demand for our products. Although steel and iron ore production have been considered “essential” by the states in which we operate, certain of our facilities and construction activities were temporarily idled during the second quarter of 2020. Most of these temporarily idled facilities were restarted during the second quarter, and the remaining operations were restarted during the third quarter. Dearborn Works' hot strip mill, anneal and temper operations and AK Coal remain permanently idled as part of the permanent cost reduction efforts. Our Columbus and Monessen facilities acquired through the AM USA Transaction are temporarily idled due to the COVID-19 pandemic.

Basis of Consolidation

The condensed consolidated financial statements consolidate our accounts and the accounts of our wholly owned subsidiaries, all subsidiaries in which we have a controlling interest and VIEs for which we are the primary beneficiary. All intercompany transactions and balances are eliminated upon consolidation.

Investments in Affiliates

We have investments in several businesses accounted for using the equity method of accounting. These investments are included within our Steelmaking segment. We review an investment for impairment when circumstances indicate that a loss in value below its carrying amount is other than temporary. Investees and equity ownership percentages are presented below:

Investee	Equity Ownership Percentage
Combined Metals of Chicago, LLC	40.0%
Spartan Steel Coating, LLC	48.0%

As of December 31, 2019, our 23% ownership in Hibbing was recorded as an equity method investment. As a result of the acquisition of ArcelorMittal USA, we acquired an additional 62.3% ownership interest in Hibbing. As of December 31, 2020, our ownership in the Hibbing joint venture was 85.3% and was fully consolidated within our operating results with a noncontrolling interest.

We recorded a basis difference for Spartan Steel of $33 million as part of the AK Steel Merger. The basis difference relates to the excess of the fair value over the investee's carrying amount of property, plant and equipment and will be amortized over the remaining useful lives of the underlying assets.

As of December 31, 2020, our investment in affiliates of $105 million was classified in Other non-current assets. As of December 31, 2019, our investment in affiliates of $18 million was classified in Other non-current liabilities.

Significant Accounting Policies

We consider the following policies to be beneficial in understanding the judgments involved in the preparation of our consolidated financial statements and the uncertainties that could impact our financial condition, results of operations and cash flows. Certain prior period amounts have been reclassified to conform with the current year presentation.

Use of Estimates

The preparation of financial statements in conformity with GAAP 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 revenues and expenses during the reporting period. Our mineral reserves; future realizable cash flow; environmental, reclamation and closure obligations; valuation of business combinations, long-lived assets, inventory, tax assets and post-employment, post-retirement and other employee benefit liabilities; reserves for contingencies and litigation require the use of various management estimates and assumptions. Actual results could differ from estimates. Management reviews its estimates on an ongoing basis. Changes in facts and circumstances may alter such estimates and affect the results of operations and financial position in future periods.

75

Business Combinations

Assets acquired and liabilities assumed in a business combination are recognized and measured based on their estimated fair values at the acquisition date, while the acquisition-related costs are expensed as incurred. Any excess of the purchase consideration when compared to the fair value of the net tangible and intangible assets acquired, if any, is recorded as goodwill. We engaged independent valuation specialists to assist with the determination of the fair value of assets acquired, liabilities assumed, noncontrolling interest, and goodwill, for the Acquisitions. If the initial accounting for the business combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded. Subsequent to the acquisition date, and not later than one year from the acquisition date, we will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the date of the acquisition. Any adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period the adjustment arises.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and on deposit as well as all short-term securities held for the primary purpose of general liquidity. We consider investments in highly liquid debt instruments with an original maturity of three months or less from the date of acquisition and longer maturities when funds can be withdrawn in three months or less without a significant penalty to be cash equivalents. We routinely monitor and evaluate counterparty credit risk related to the financial institutions in which our short-term investment securities are held.

Trade Accounts Receivable and Allowance for Credit Loss

Trade accounts receivable are recorded at the point control transfers and represent the amount of consideration we expect to receive in exchange for transferred goods and do not bear interest. We establish provisions for expected lifetime losses on accounts receivable at the time a receivable is recorded based on historical experience, customer credit quality and forecasted economic conditions. We regularly review our accounts receivable balances and the allowance for credit loss and establish or adjust the allowance as necessary using the specific identification method in accordance with CECL. We evaluate the aggregation and risk characteristics of receivable pools and develop loss rates that reflect historical collections, current forecasts of future economic conditions over the time horizon we are exposed to credit risk, and payment terms or conditions that may materially affect future forecasts.

Inventories

Inventories are generally stated at the lower of cost or net realizable value using average cost, excluding depreciation and amortization. Certain iron ore inventories are stated at the lower of cost or market using the LIFO method.

Refer to NOTE 2 - SUPPLEMENTARY FINANCIAL STATEMENT INFORMATION for further information.

Derivative Financial Instruments and Hedging Activities

We are exposed to certain risks related to the ongoing operations of our business, including those caused by changes in commodity prices and energy rates. We have established policies and procedures, including the use of certain derivative instruments, to manage such risks, if deemed necessary.

Derivative financial instruments are recognized as either assets or liabilities in the Statements of Consolidated Financial Position and measured at fair value. On the date a qualifying hedging instrument is executed, we designate the hedging instrument as a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge). We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific firm commitments or forecasted transactions. We also formally assess, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of the related hedged items. When it is determined that a derivative is not highly effective as a hedge, we discontinue hedge accounting prospectively and record all future changes in fair value in the period of the instrument's earnings or losses.

For derivative instruments that have been designated as cash flow hedges, the changes in fair value are recorded in Accumulated other comprehensive loss. Amounts recorded in Accumulated other comprehensive loss are

76

reclassified to earnings or losses in the period the underlying hedged transaction affects earnings or when the underlying hedged transaction is no longer reasonably possible of occurring.

For derivative instruments that have not been designated as cash flow hedges, such as provisional pricing arrangements, changes in fair value are recorded in the period of the instrument's earnings or losses.

Refer to Revenue Recognition below for discussion of derivatives recorded as a result of pricing terms in our sales contracts. Additionally, refer to NOTE 15 - DERIVATIVE INSTRUMENTS for further information.

Property, Plant and Equipment

Our properties are stated at the lower of cost less accumulated depreciation. Depreciation of plant and equipment is computed principally by the straight-line method based on estimated useful lives. Depreciation continues to be recognized when operations are idled temporarily. Depreciation and depletion are recorded over the following estimated useful lives:

Asset Class	Basis	Life
Land, land improvements and mineral rights
Land and mineral rights	Units of production	Life of mine
Land improvements	Straight line	20 to 45 years
Buildings	Straight line	20 to 45 years
Equipment	Straight line/Double declining balance	3 to 20 years

Refer to NOTE 6 - PROPERTY, PLANT AND EQUIPMENT for further information.

Goodwill

Goodwill represents the excess purchase price paid over the fair value of the net assets during an acquisition. Goodwill is not amortized, but is assessed for impairment on an annual basis on October 1 (or more frequently if necessary).

Other Intangible Assets and Liabilities

Intangible assets and liabilities are subject to periodic amortization on a straight-line basis over their estimated useful lives as follows:

Type	Basis	Useful Life
Intangible assets:
Customer relationships	Straight line	18 years
Developed technology	Straight line	17 years
Trade names and trademarks	Straight line	10 years
Mining permits	Straight line	Life of mine
Intangible liabilities:
Above-market supply contracts	Straight line	Contract term

Refer to NOTE 7 - GOODWILL AND INTANGIBLE ASSETS AND LIABILITIES for further information.

Leases

We determine if an arrangement contains a lease at inception. We recognize right-of-use assets and lease liabilities associated with leases based on the present value of the future minimum lease payments over the lease term at the commencement date. Lease terms reflect options to extend or terminate the lease when it is reasonably certain that the option will be exercised. For short-term leases (leases with an initial lease term of 12 months or less), right-of-use assets and lease liabilities are not recognized in the consolidated balance sheet, and lease expense is recognized on a straight-line basis over the lease term.

Refer to NOTE 13 - LEASE OBLIGATIONS for further information.

77

Asset Impairment

We monitor conditions that may affect the carrying value of our long-lived tangible and intangible assets when events and circumstances indicate that the carrying value of the asset groups may not be recoverable. In order to determine if assets have been impaired, assets are grouped and tested at the lowest level for which identifiable, independent cash flows are available ("asset group"). The measurement of the impairment loss to be recognized is based on the difference between the fair value and the carrying value of the asset group. Fair value can be determined using a market approach, income approach or cost approach.

For the years ended December 31, 2020, 2019 and 2018, no impairment indicators were present that would indicate the carrying value of any of our asset groups may not be recoverable; as a result, no impairment assessments were required.

Fair Value Measurements

ASC Topic 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for classification of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own views about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized below:

•Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 — Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

•Level 3 — Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

The classification of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement in its entirety.

Refer to NOTE 9 - FAIR VALUE OF FINANCIAL INSTRUMENTS and NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Pensions and Other Postretirement Benefits

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits as part of our total compensation and benefits programs.

We recognize the funded or unfunded status of our pension and OPEB obligations on our December 31, 2020 and 2019 Statements of Consolidated Financial Position based on the difference between the market value of plan assets and the actuarial present value of our retirement obligations on that date, on a plan-by-plan basis. If the plan assets exceed the pension and OPEB obligations, the amount of the surplus is recorded as an asset; if the pension and OPEB obligations exceed the plan assets, the amount of the underfunded obligations is recorded as a liability. Year-end balance sheet adjustments to pension and OPEB assets and obligations are recorded as Accumulated other comprehensive loss in the Statements of Consolidated Financial Position.

The actuarial estimates of the PBO and APBO incorporate various assumptions including the discount rates, the rates of increases in compensation, healthcare cost trend rates, mortality, retirement timing and employee turnover. The discount rate is determined based on the prevailing year-end rates for high-grade corporate bonds with a duration matching the expected cash flow timing of the benefit payments from the various plans. The remaining assumptions are based on our estimates of future events by incorporating historical trends and future expectations. The amount of net periodic cost that is recorded in the Statements of Consolidated Operations consists of several components including service cost, interest cost, expected return on plan assets, and amortization of previously unrecognized amounts. Service cost represents the value of the benefits earned in the current year by the participants. Interest cost represents the cost associated with the passage of time. Certain items, such as plan amendments, gains and/or losses resulting from differences between actual and assumed results for demographic

78

and economic factors affecting the obligations and assets of the plans, and changes in other assumptions are subject to deferred recognition for income and expense purposes. The expected return on plan assets is determined utilizing the weighted average of expected returns for plan asset investments in various asset categories based on historical performance, adjusted for current trends. Service costs are classified within Cost of goods sold, Selling, general and administrative expenses and Miscellaneous – net while the interest cost, expected return on assets, amortization of prior service costs/credits, net actuarial gain/loss, and other costs are classified within Other non-operating income.

Refer to NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Labor Agreements

At December 31, 2020, we employed approximately 25,000 people, of which approximately 18,500 were represented by labor unions under various agreements. We have agreements that will expire at five locations in 2021 and sixteen locations in 2022. Workers at some of our North American facilities are covered by agreements with the USW or other unions that have various expiration dates.

Asset Retirement Obligations

Asset retirement obligations are recognized when incurred and recorded as liabilities at fair value. The fair value of the liability is determined as the discounted value of the expected future cash flows. The asset retirement obligation is accreted over time through periodic charges to earnings. In addition, the asset retirement cost is capitalized and amortized over the life of the related asset. Reclamation costs are adjusted periodically to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. We review, on an annual basis, unless otherwise deemed necessary, the asset retirement obligation for each applicable operation in accordance with the provisions of ASC Topic 410, Asset Retirement and Environmental Obligations. We perform an in-depth evaluation of the liability every three years in addition to our routine annual assessments.

Future reclamation costs for inactive operations are accrued based on management’s best estimate at the end of each period of the costs expected to be incurred at a site. Such cost estimates include, where applicable, ongoing maintenance and monitoring costs. Changes in estimates at inactive operations are reflected in earnings in the period an estimate is revised.

Refer to NOTE 14 - ASSET RETIREMENT OBLIGATIONS for further information.

Environmental Remediation Costs

We have a formal policy for environmental protection and restoration. Certain of our operating activities are subject to various laws and regulations governing protection of the environment. We conduct our operations to protect the public health and environment and believe our operations are in compliance with applicable laws and regulations in all material respects. Our environmental liabilities, including obligations for known environmental remediation exposures, have been recognized based on the estimated cost of investigation and remediation at each site. If the cost can only be estimated as a range of possible amounts with no point in the range being more likely, the minimum of the range is accrued. Future expenditures are discounted unless the amount and timing of the cash disbursements cannot be reasonably estimated. It is possible that additional environmental obligations could be incurred, the extent of which cannot be assessed. Potential insurance recoveries have not been reflected in the determination of the liabilities.

Refer to NOTE 21 - COMMITMENTS AND CONTINGENCIES for further information.

Revenue Recognition

Sales are recognized when our performance obligations are satisfied. Generally, our performance obligations are satisfied, control of our products is transferred and revenue is recognized at a single point in time, when title transfers to our customer for product shipped according to shipping terms. Shipping and other transportation costs charged to customers are treated as fulfillment activities and are recorded in both revenue and cost of sales at the time control is transferred to the customer. Refer to NOTE 4 - REVENUES for further information.

Repairs and Maintenance

Repairs, maintenance and replacement of components are expensed as incurred. The cost of major equipment overhauls is capitalized and depreciated over the estimated useful life, which is the period until the next scheduled overhauls. All other planned and unplanned repairs and maintenance costs are expensed when incurred.

79

Share-Based Compensation

The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. A correlation matrix of historical and projected stock prices was developed for both the Company and its predetermined peer group of mining and metals companies. The fair value assumes that the performance objective will be achieved. The expected term of the grant represents the time from the grant date to the end of the service period. We estimate the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds, with a term commensurate with the remaining performance period.

The fair value of the restricted stock units is determined based on the closing price of our common shares on the grant date.

Upon vesting of share-based compensation awards, we issue shares from treasury shares before issuing new shares. Forfeitures are recognized when they occur.

The fair value of stock options is estimated on the date of grant using a Black-Scholes model using the grant date price of our common shares and option exercise price, and assumptions regarding the option’s expected term, the volatility of our common shares, the risk-free interest rate, and the dividend yield over the option’s expected term.

Refer to NOTE 11 - STOCK COMPENSATION PLANS for additional information.

Income Taxes

Income taxes are based on income for financial reporting purposes, calculated using tax rates by jurisdiction, and reflect a current tax liability or asset for the estimated taxes payable or recoverable on the current year tax return and expected annual changes in deferred taxes. Any interest or penalties on income tax are recognized as a component of Income tax benefit (expense).

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized within Net income (loss) in the period that includes the enactment date.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial results of operations.

Accounting for uncertainty in income taxes recognized in the financial statements requires that a tax benefit from an uncertain tax position be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on technical merits.

See NOTE 12 - INCOME TAXES for further information.

Discontinued Operations

During 2018, we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and sold all of the assets of our Asia Pacific Iron Ore business through a series of sales to third parties. As a result of our exit, management determined that our Asia Pacific Iron Ore mining operations met the criteria to be classified as held for sale and a discontinued operation under ASC Topic 205, Presentation of Financial

80

Statements. As such, all current and historical Asia Pacific Iron Ore operating results are classified within discontinued operations.

Foreign Currency

Our financial statements are prepared with the U.S. dollar as the reporting currency and the functional currency of all subsidiaries is the U.S. dollar, except for our European Operations for which the functional currency is the Euro. In August 2018, management determined that there were significant changes in economic factors related to our Australian subsidiaries. The change in economic factors was a result of the sale and conveyance of substantially all assets and liabilities of our Australian subsidiaries to third parties, representing a significant change in operations. As such, the functional currency for the Australian subsidiaries changed from the Australian dollar to the U.S. dollar and all remaining Australian denominated monetary balances will be remeasured prospectively through the Statements of Consolidated Operations.

As a result of the liquidation of the Australian subsidiaries' assets, the historical impact of foreign currency translation recorded in Accumulated other comprehensive loss in the Statements of Consolidated Financial Position of $228 million was reclassified and recognized as a gain in Income (loss) from discontinued operations, net of tax in the Statements of Consolidated Operations for the year ended December 31, 2018.

Earnings Per Share

We present both basic and diluted EPS amounts for continuing operations and discontinued operations. Total basic EPS amounts are calculated by dividing Net income (loss) attributable to Cliffs shareholders, less the earnings allocated to our Series B Participating Redeemable Preferred Stock, by the weighted average number of common shares outstanding during the period presented.

Total diluted EPS amounts are calculated by dividing Net income (loss) attributable to Cliffs shareholders by the weighted average number of common shares, common share equivalents under stock plans using the treasury-stock method, common share equivalents of the Series B Participating Redeemable Preferred Stock using the if-converted method and the calculated common share equivalents in excess of the conversion rate related to our 1.50% 2025 Convertible Senior Notes using the treasury-stock method. Common share equivalents are excluded from EPS computations in the periods in which they have an anti-dilutive effect.

See NOTE 8 - DEBT AND CREDIT FACILITIES and NOTE 20 - EARNINGS PER SHARE for further information.

Variable Interest Entities

We assess whether we have a variable interest in legal entities in which we have a financial relationship and, if so, whether or not those entities are VIEs. A VIE is an entity with insufficient equity at risk for the entity to finance its activities without additional subordinated financial support or in which equity investors lack the characteristics of a controlling financial interest. If an entity is determined to be a VIE, we evaluate whether we are the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. We conclude that we are the primary beneficiary and consolidate the VIE if we have both (i) the power to direct the activities of the VIE that most significantly influence the VIE's economic performance and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Refer to NOTE 19 - VARIABLE INTEREST ENTITIES for additional information.

Recent Accounting Pronouncements

Issued and Adopted

On March 2, 2020, the SEC issued a final rule that amended the disclosure requirements related to certain registered securities under SEC Regulation S-X, Rule 3-10, which required separate financial statements for subsidiary issuers and guarantors of registered debt securities unless certain exceptions are met. The final rule replaces the previous requirement under Rule 3-10 to provide condensed consolidating financial information in the registrant’s financial statements with a requirement to provide alternative financial disclosures (which include summarized financial information of the parent and any issuers and guarantors, as well as other qualitative disclosures) in either the registrant’s Management's Discussion and Analysis of Financial Condition and Results of Operations or its financial statements, in addition to other simplifications. The final rule is effective for filings on or after January 4, 2021, and early adoption is permitted. We elected to early adopt this disclosure update for the period ended March 31, 2020. As a result, we have excluded the footnote disclosures required under the previous Rule 3-10, and applied the final rule by including the summarized financial information and qualitative disclosures in Part II -

81

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of this Annual Report on Form 10-K and Exhibit 22, filed herewith.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except for short-term leases. For lessees, leases are classified as either operating or finance leases. We adopted this standard on its effective date of January 1, 2019 using the optional alternative approach, which requires application of the new guidance at the beginning of the standard's effective date. Adoption of the updated standard did not have a material effect on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which introduces a new accounting model, CECL. CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. CECL utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. We elected to early adopt this standard on December 31, 2019. Upon adoption, the updated standard did not have a material effect on our consolidated financial statements.

Issued and Not Effective

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). This update requires certain convertible instruments to be accounted for as a single liability measured at its amortized cost. Additionally, the update requires the use of the "if-converted" method, removing the treasury stock method, when calculating diluted shares. The two methods of adoption are the full and modified retrospective approaches. We expect to utilize the modified retrospective approach. Using this approach, the guidance shall be applied to transactions outstanding as of the beginning of the fiscal year in which the amendment is adopted. The final rule is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We are continuing to evaluate the impact of this update to our consolidated financial statements and would expect to adopt at the required adoption date of January 1, 2022.

NOTE 3 - ACQUISITIONS

In 2020, we acquired two major steelmakers, AK Steel and ArcelorMittal USA, vertically integrating our legacy iron ore business with steel production. Our fully-integrated portfolio includes custom-made pellets and HBI; flat-rolled carbon steel, stainless, electrical, plate, tinplate and long steel products; as well as carbon and stainless steel tubing, hot and cold stamping and tooling. The AK Steel Merger combined Cliffs, a producer of iron ore pellets, with AK Steel, a producer of flat-rolled carbon, stainless and electrical steel products, to create a vertically integrated producer of value-added iron ore and steel products. The AM USA Transaction transformed us into a fully-integrated steel enterprise with the size and scale to achieve improved through-the-cycle margins.

We now have a presence across the entire steel manufacturing process, from mining to pelletizing to the development and production of finished high value steel products. The combination is expected to create significant opportunities to generate additional value from market trends across the entire steel value chain and enable more consistent, predictable performance through normal market cycles.

Acquisition of ArcelorMittal USA

Overview

On December 9, 2020, pursuant to the terms of the AM USA Transaction Agreement, we purchased ArcelorMittal USA from ArcelorMittal. In connection with the closing of the AM USA Transaction, as contemplated by the terms of the AM USA Transaction Agreement, ArcelorMittal’s former joint venture partner in Kote and Tek exercised its put right pursuant to the terms of the Kote and Tek joint venture agreements. As a result, we purchased all of such joint venture partner’s interests in Kote and Tek. Following the closing of the AM USA Transaction, we own 100% of the interests in Kote and Tek.

Following the acquisition, the operating results of ArcelorMittal USA are included in our consolidated financial statements. For the period subsequent to the acquisition (December 9, 2020 through December 31, 2020), ArcelorMittal USA generated Revenues of $446 million and a loss of $40 million included within Net income (loss) attributable to Cliffs shareholders, which included $21 million related to amortization of the fair value inventory step-up.

Additionally, we incurred acquisition-related costs excluding severance costs of $26 million for the year ended December 31, 2020, which were recorded in Acquisition-related costs on the Statements of Consolidated Operations.

The AM USA Transaction was accounted for under the acquisition method of accounting for business combinations.

The fair value of the total purchase consideration was determined as follows:

	(In Millions)
Fair value of Cliffs common shares issued	$	990
Fair value of Series B Participating Redeemable Preferred Stock issued	738
Fair value of settlement of a pre-existing relationship	237

Valuation Assumption and Preliminary Purchase Price Allocation

We estimated fair values at December 9, 2020 for the preliminary allocation of consideration to the net tangible and intangible assets acquired and liabilities assumed in connection with the AM USA Transaction. During the measurement period, we will continue to obtain information to assist in finalizing the fair value of assets acquired and liabilities assumed, which may differ materially from these preliminary estimates. If we determine any measurement period adjustments are material, we will apply those adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. We are in the process of conducting a valuation of the assets acquired and liabilities assumed related to the AM USA Transaction, most notably, inventories, personal and real property, mineral reserves, leases, investments, deferred taxes, asset retirement obligations, pension and OPEB liabilities, and the final allocation will be made when completed, including the result of any identified goodwill. Accordingly, the provisional measurements noted below are preliminary and subject to modification in the future.

The goodwill resulting from the acquisition of ArcelorMittal USA primarily represents the growth opportunities in the automotive, construction, appliances, infrastructure and machinery and equipment markets, as well as any synergistic benefits to be realized from the AM USA Transaction and was assigned to our flat steel operations within our Steelmaking segment. Goodwill is expected to be deductible for U.S. federal income tax purposes.

Acquisition of AK Steel

Overview

On March 13, 2020, pursuant to the AK Steel Merger Agreement, we completed the acquisition of AK Steel, in which we were the acquirer. As a result of the AK Steel Merger, each share of AK Steel common stock issued and outstanding immediately prior to the effective time of the AK Steel Merger (other than excluded shares) was converted into the right to receive 0.400 Cliffs common shares and, if applicable, cash in lieu of any fractional Cliffs common shares.

Following the acquisition, the operating results of AK Steel are included in our consolidated financial statements. For the period subsequent to the acquisition (March 13, 2020 through December 31, 2020), AK Steel generated Revenues of $3,573 million and a loss of $302 million included within Net income (loss) attributable to Cliffs shareholders, which included $74 million and $35 million related to amortization of the fair value inventory step-up and severance costs, respectively.

Additionally, we incurred acquisition-related costs excluding severance costs of $26 million for the year ended December 31, 2020, which were recorded in Acquisition-related costs on the Statements of Consolidated Operations.

Refer to NOTE 8 - DEBT AND CREDIT FACILITIES for information regarding debt transactions executed in connection with the AK Steel Merger.

The AK Steel Merger was accounted for under the acquisition method of accounting for business combinations. The acquisition date fair value of the consideration transferred totaled $1,535 million. The following tables summarize the consideration paid for AK Steel and the estimated fair values of the assets acquired and liabilities assumed at the acquisition date.

Valuation Assumption and Preliminary Purchase Price Allocation

We estimated fair values at March 13, 2020 for the preliminary allocation of consideration to the net tangible and intangible assets acquired and liabilities assumed in connection with the AK Steel Merger. During the measurement period, we will continue to obtain information to assist in finalizing the fair value of assets acquired and liabilities assumed, which may differ materially from these preliminary estimates. If we determine any measurement period adjustments are material, we will apply those adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. We are in the process of conducting a valuation of the assets acquired and liabilities assumed related to the AK Steel Merger, most notably, personal and real property, leases, deferred taxes, asset retirement obligations and intangible assets and liabilities, and the final allocation will be made when completed, including the result of any identified goodwill. Accordingly, the provisional measurements noted below are preliminary and subject to modification in the future.

Total net assets acquired	$	1,535	$	—	$	1,535

During the period subsequent to the AK Steel Merger, we made certain measurement period adjustments to the acquired assets and liabilities assumed due to clarification of information utilized to determine fair value during the measurement period. The Inventories measurement period adjustments of $243 million resulted in a favorable impact of $8 million to Cost of goods sold for the year ended December 31, 2020.

The goodwill resulting from the acquisition of AK Steel was assigned to our downstream Tubular and Tooling and Stamping operating segments. Goodwill is calculated as the excess of the purchase price over the net identifiable assets recognized and primarily represents the growth opportunities in light weighting solutions to automotive customers, as well as any synergistic benefits to be realized. Goodwill from the AK Steel Merger is not expected be deductible for income tax purposes.

The preliminary purchase price allocated to identifiable intangible assets and liabilities acquired was:

Pro Forma Results

The following table provides unaudited pro forma financial information, prepared in accordance with Topic 805, for the years ended December 31, 2020 and 2019, as if ArcelorMittal USA and AK Steel had been acquired as of January 1, 2019:

	(In Millions)
	Year Ended December 31,
	2020		2019
Revenues	$	12,837	$	17,163
Net income (loss) attributable to Cliffs shareholders	(520)		(11)

The unaudited pro forma financial information has been calculated after applying our accounting policies and adjusting the historical results with pro forma adjustments, net of tax, that assume the Acquisitions occurred on January 1, 2019. Significant pro forma adjustments include the following:

1.The elimination of intercompany revenues between Cliffs and ArcelorMittal USA and AK Steel of $844 million and $1,499 million for the years ended December 31, 2020 and 2019, respectively.

2.The 2020 pro forma net loss was adjusted to exclude $96 million of non-recurring inventory acquisition accounting adjustments incurred during the year ended December 31, 2020. The 2019 pro forma net loss was adjusted to include $362 million of non-recurring inventory acquisition accounting adjustments for the year ended December 31, 2019.

3.The elimination of non-recurring transaction costs incurred by Cliffs, AK Steel and ArcelorMittal USA in connection with the Acquisitions were $93 million for the year ended December 31, 2020. The 2019 pro forma net loss was adjusted to include $93 million of non-recurring transaction cost adjustments for the year ended December 31, 2019.

4.The 2020 pro forma net loss was adjusted to exclude restructuring costs of $1,820 million of non-recurring costs incurred by ArcelorMittal USA prior to the AM USA Transaction.

5.The 2020 and 2019 pro forma net losses were adjusted to exclude $140 million and $129 million for the years ended December 31, 2020 and 2019, respectively, for the impact of reversal of the fees charged for management, financial and legal services under the Industrial Franchise Agreement with the former parent.

6.Total other pro forma adjustments included reduced expenses of $32 million for the year ended December 31, 2020, primarily due to decreased depreciation expense and pension and OPEB expense, offset partially by increased interest and amortization expense.

7.Total other pro forma adjustments included an expense of $76 million for the year ended December 31, 2019, primarily due to increased interest, amortization and pension and OPEB expense, offset partially by decreased depreciation expense.

8.The income tax impact of pro forma transaction adjustments that affect Net income (loss) attributable to Cliffs shareholders at a statutory rate of 24.3% resulted in an increased benefit to Income tax benefit (expense) of $170 million and $117 million for the years ended December 31, 2020 and 2019, respectively.

The unaudited pro forma financial information does not reflect the potential realization of synergies or cost savings, nor does it reflect other costs relating to the integration of the acquired companies. This unaudited pro forma financial information should not be considered indicative of the results that would have actually occurred if the Acquisitions had been consummated on January 1, 2019, nor are they indicative of future results.

NOTE 4 - REVENUES

We generate our revenue through product sales, in which shipping terms generally indicate when we have fulfilled our performance obligations and transferred control of products to our customer. Our revenue transactions consist of a single performance obligation to transfer promised goods. Our contracts with customers usually define the mechanism for determining the sales price, which is generally fixed upon transfer of control, but the contracts generally do not impose a specific quantity on either party. Quantities to be delivered to the customer are generally determined at a point near the date of delivery through purchase orders or other written instructions we receive from the customer. Spot market sales are made through purchase orders or other written instructions. We consider our performance obligation to be complete and recognize revenue when control transfers in accordance with shipping terms.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring product. We reduce the amount of revenue recognized for estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized. Payment terms are consistent with terms standard to the markets we serve. Sales taxes collected from customers are excluded from revenues.

Prior to the AM USA Transaction, we had a supply agreement with ArcelorMittal USA, which included supplemental revenue or refunds based on the HRC price in the year the iron ore was consumed in ArcelorMittal USA's blast furnaces. As control transferred prior to consumption, the supplemental revenue was recorded in accordance with Topic 815. All sales occurring subsequent to the AM USA Transaction are intercompany and eliminated in consolidation. Included within Revenues related to Topic 815 for the supplemental revenue portion of the supply agreement is derivative revenue of $122 million, $78 million and $426 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Prior to the AK Steel Merger, our iron ore pellet sales agreement with Severstal Dearborn, LLC, subsequently assumed by AK Steel, required supplemental payments to be paid by the customer during the period from 2009 through 2013. Installment amounts received under this arrangement in excess of sales were classified as deferred revenue in the Statements of Consolidated Financial Position upon receipt of payment and the revenue was recognized over the term of the supply agreement, which had extended until 2022, in equal annual installments. As a result of the termination of that iron ore pellet sales agreement, we realized $35 million of deferred revenue, which was recognized within Realization of deferred revenue in the Statements of Consolidated Operations during the year ended December 31, 2020.

We have certain other sales agreements that require customers to pay in advance. Payments received pursuant to these agreements prior to revenue being recognized are recorded as deferred revenue in Other current liabilities.

NOTE 5 - SEGMENT REPORTING

We are vertically integrated from the mining of iron ore and coal; to production of metallics and coke; through iron making, steelmaking, rolling, finishing; and to downstream tubing, stamping and tooling. We are organized into four operating segments based on our differentiated products - Steelmaking, Tubular, Tooling and Stamping, and European Operations. Our previous Mining and Pelletizing segment is included within the Steelmaking operating segment as iron ore pellets are a primary raw material for our steel products. We have one reportable segment - Steelmaking. The operating segment results of our Tubular, Tooling and Stamping, and European Operations that do not constitute reportable segments are combined and disclosed in the Other Businesses category. Our Steelmaking

91

segment is the largest flat-rolled steel producer supported by being the largest iron ore pellet producer in North America, primarily serving the automotive, infrastructure and manufacturing, and distributors and converters markets. Our Other Businesses primarily include the operating segments that provide customer solutions with carbon and stainless steel tubing products, advanced-engineered solutions, tool design and build, hot- and cold-stamped steel components, and complex assemblies. All intersegment transactions were eliminated in consolidation.

We evaluate performance on an operating segment basis, as well as a consolidated basis, based on Adjusted EBITDA, which is a non-GAAP measure. This measure is used by management, investors, lenders and other external users of our financial statements to assess our operating performance and to compare operating performance to other companies in the steel industry. In addition, management believes Adjusted EBITDA is a useful measure to assess the earnings power of the business without the impact of capital structure and can be used to assess our ability to service debt and fund future capital expenditures in the business.

Holders may convert their 1.50% 2025 Convertible Senior Notes at their option at any time prior to the close of business on the business day immediately preceding July 15, 2024, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2018, if the last reported sale price of our common shares, par value $0.125 per share, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business day period after any five-consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 1.50% 2025 Convertible Senior Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common shares and the conversion rate on each such trading day; (3) if we call the notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after July 15, 2024 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their 1.50% 2025 Convertible Senior Notes at any time, regardless of the foregoing circumstances. Upon conversion, we will pay or deliver, as the case may be, cash, common shares or a combination of cash and common shares, at our election.

Upon the issuance of the 1.50% 2025 Convertible Senior Notes the initial conversion rate was 122.4365 common shares per $1,000 principal, with a conversion price of $8.17 per common share. The conversion rate is subject to adjustment in some circumstances, including the payment of dividends on common shares, but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its 1.50% 2025 Convertible Senior Notes in connection with such a corporate event or notice of redemption, as the case may be. As of December 31, 2020, the conversion rate was 129.2985 common shares per $1,000 principal amount of 1.50% 2025 Convertible Senior Notes.

We may not redeem the 1.50% 2025 Convertible Senior Notes prior to January 15, 2022. We may redeem all or any portion of the 1.50% 2025 Convertible Senior Notes, for cash at our option on or after January 15, 2022 if the last reported sale price of our common shares has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30-consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the 1.50% 2025 Convertible Senior Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

103

It is our current intent to settle conversions through combination settlement or fully in cash.  Our ability to settle conversions through combination settlement and cash settlement will be subject to restrictions in the agreement governing our ABL Facility and may be subject to restrictions in agreements governing our future debt.

If we undergo a fundamental change as defined in the indenture, holders may require us to repurchase for cash all or any portion of their 1.50% 2025 Convertible Senior Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 1.50% 2025 Convertible Senior Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the notes, we separated the 1.50% 2025 Convertible Senior Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that did not have associated convertible features. The carrying amount of the equity component of $86 million representing the conversion option was determined by deducting the fair value of the liability component from the par value of the notes. The difference represents the debt discount that is amortized to interest expense over the term of the notes. The equity component is not remeasured as long as it continues to qualify for equity classification.

Other Outstanding Unsecured Senior Notes

The following represents a summary of our other unsecured senior notes' maturity and interest payable due dates:

Debt Instrument	Maturity	Interest Payable (until maturity)
5.75% 2025 Senior Notes	March 1, 2025	March 1 and September 1
5.875% 2027 Senior Notes	June 1, 2027	June 1 and December 1
6.25% 2040 Senior Notes	October 1, 2040	April 1 and October 1

The senior notes are unsecured obligations and rank equally in right of payment with all our other existing and future unsecured and unsubordinated indebtedness. There are no subsidiary guarantees of the interest and principal amounts for the 6.25% 2040 Senior Notes. The 5.75% 2025 Senior Notes and 5.875% 2027 Senior Notes are guaranteed on a senior unsecured basis by our material direct and indirect wholly owned domestic subsidiaries and, therefore, are structurally senior to any of our existing and future indebtedness that is not guaranteed by such guarantors and are structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries that do not guarantee the 5.75% 2025 Senior Notes and 5.875% 2027 Senior Notes.

We may redeem the 5.75% 2025 Senior Notes, in whole or in part, on or after March 1, 2020, at the redemption prices set forth in the indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption.

We may redeem the 5.875% 2027 Senior Notes, in whole or in part, on or after June 1, 2022, at the redemption prices set forth in the indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, and prior to June 1, 2022, at a redemption price equal to 100% of the principal amount thereof plus a “make-whole” premium set forth in the indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. We may also redeem up to 35% of the aggregate principal amount of the 5.875% 2027 Senior Notes on or prior to June 1, 2022 at a redemption price equal to 105.875% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of redemption with the net cash proceeds of one or more equity offerings.

The 6.25% 2040 Senior Notes may be redeemed any time at our option upon not less than 30, nor more than 60, days' prior notice is sent to the holders. The 6.25% 2040 Senior Notes are redeemable at a redemption price equal to the greater of (1) 100% of the principal amount of the notes to be redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted to the redemption date on a semi-annual basis at the treasury rate plus 40 basis points, plus accrued and unpaid interest, if any, to, but not including, the date of redemption.

In addition, if a change of control triggering event, as defined in the applicable indenture, occurs with respect to the unsecured notes, we will be required to offer to purchase the notes of the applicable series at a purchase price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of purchase.

104

The terms of the unsecured notes contain certain customary covenants; however, there are no financial covenants.

ABL Facility

On March 13, 2020, in connection with the AK Steel Merger, we entered into a new ABL Facility with various financial institutions to replace and refinance Cliffs’ Former ABL Facility and AK Steel Corporation’s former revolving credit facility. The ABL Facility will mature upon the earlier of March 13, 2025 or 91 days prior to the maturity of certain other material debt and provided for up to $2 billion in borrowings, including a $555 million sublimit for the issuance of letters of credit and a $125 million sublimit for swingline loans. Availability under the ABL Facility is limited to an eligible borrowing base, as applicable, determined by applying customary advance rates to eligible accounts receivable, inventory and certain mobile equipment.

On March 27, 2020, the ABL Facility was amended, by and among Cliffs, the lenders and the administrative agent. The amendment modified the ABL Facility to, among other things, provide for a new FILO tranche B of commitments in the aggregate amount of $150 million by exchanging existing commitments under the ABL Facility. The total commitments under the ABL Facility after giving effect to the amendment remained at $2 billion. The terms and conditions (other than the pricing) that apply to the FILO tranche are substantially the same as the terms and conditions that apply to the tranche A facility of the ABL Facility immediately prior to the amendment.

On December 9, 2020, we entered into the ABL Amendment with various financial institutions. The ABL Amendment modified the ABL Facility to, among other things, increase the amount of tranche A revolver commitments available thereunder by an additional $1.5 billion and increase certain dollar baskets related to certain negative covenants that apply to the ABL Facility. After giving effect to the ABL Amendment, the aggregate principal amount of tranche A revolver commitments under the ABL Facility is $3.35 billion and the aggregate principal amount of FILO tranche B revolver commitments under the ABL Facility remains at $150 million.

The ABL Facility and certain bank products and hedge obligations are guaranteed by certain of our existing wholly owned U.S. subsidiaries and are required to be guaranteed by certain of our future U.S. subsidiaries. Amounts outstanding under the ABL Facility are secured by (i) a first-priority security interest in the accounts receivable and other rights to payment, inventory, as-extracted collateral, certain investment property, deposit accounts, securities accounts, certain general intangibles and commercial tort claims, certain mobile equipment, commodities accounts and other related assets of ours, the other borrowers and the guarantors, and proceeds and products of each of the foregoing (collectively, the “ABL Collateral”) and (ii) a second-priority security interest in substantially all of our assets and the assets of the other borrowers and the guarantors other than the ABL Collateral.

Borrowings under the ABL Facility bear interest, at our option, at a base rate or, if certain conditions are met, a LIBOR rate, in each case plus an applicable margin. We may amend our ABL Facility to replace the LIBOR rate with one or more secured overnight financing based rates or an alternative benchmark rate, giving consideration to any evolving or then-existing convention for similar dollar denominated syndicated credit facilities for such alternative benchmarks.

The ABL Facility contains customary representations and warranties and affirmative and negative covenants including, among others, covenants regarding the maintenance of certain financial ratios if certain conditions are triggered, covenants relating to financial reporting, covenants relating to the payment of dividends on, or purchase or redemption of, our capital stock, covenants relating to the incurrence or prepayment of certain debt, covenants relating to the incurrence of liens or encumbrances, covenants relating to compliance with laws, covenants relating to transactions with affiliates, covenants relating to mergers and sales of all or substantially all of our assets and limitations on changes in the nature of our business.

The ABL Facility provides for customary events of default, including, among other things, the event of nonpayment of principal, interest, fees or other amounts, a representation or warranty proving to have been materially incorrect when made, failure to perform or observe certain covenants within a specified period of time, a cross-default to certain material indebtedness, the bankruptcy or insolvency of the Company and certain of its subsidiaries, monetary judgment defaults of a specified amount, invalidity of any loan documentation, a change of control of the Company, and ERISA defaults resulting in liability of a specified amount. If an event of default exists (beyond any applicable grace or cure period), the administrative agent may, and at the direction of the requisite number of lenders shall, declare all amounts owing under the ABL Facility immediately due and payable, terminate such lenders’ commitments to make loans under the ABL Facility and/or exercise any and all remedies and other rights under the ABL Facility. For certain events of default related to insolvency and receivership, the commitments of the lenders will be automatically terminated and all outstanding loans and other amounts will become immediately due and payable.

105

As of December 31, 2020 and 2019, we were in compliance with the ABL Facility liquidity requirements and, therefore, the springing financial covenant requiring a minimum fixed charge coverage ratio of 1.0 to 1.0 was not applicable.

The following represents a summary of our borrowing capacity under the ABL Facility:

	(In Millions)
	December 31, 2020
Available borrowing base on ABL Facility1	$	3,500
Borrowings	(1,510)
Letter of credit obligations2	(247)
Borrowing capacity available	$	1,743
1 As of December 31, 2020, the ABL Facility has a maximum borrowing base of $3.5 billion. The available borrowing base is determined by applying customary advance rates to eligible accounts receivable, inventory and certain mobile equipment.
2 We issued standby letters of credit with certain financial institutions in order to support business obligations including, but not limited to, workers' compensation, employee severance, insurance, operating agreements, IRBs and environmental obligations.

Other Financing Arrangements

Industrial Revenue Bonds

AK Steel Corporation had outstanding $66 million aggregate principal amount of fixed-rate, tax-exempt IRBs as of December 31, 2020. The weighted-average fixed rate of these IRBs is 6.86%. These IRBs are unsecured senior debt obligations that are equal in ranking with AK Steel Corporation's senior notes and AK Steel Corporation's guarantees of Cliffs' unsubordinated indebtedness. These IRBs are effectively subordinated to AK Steel Corporation’s guarantees of Cliffs’ secured indebtedness to the extent of the value of AK Steel Corporation’s assets securing such guarantees. In addition, AK Steel Corporation had outstanding $26 million aggregate principal amount of variable-rate IRBs as of December 31, 2020 that are backed by a letter of credit. These IRBs contain certain customary covenants; however, there are no financial covenants.

EDC Revolving Facility

On November 9, 2020, our Canadian subsidiaries Fleetwood Metal Industries Inc. and The Electromac Group Inc. entered into a new revolving facility with Export Development Canada. The EDC Revolving Facility enables our Tooling and Stamping business to finance the purchase of tooling and related equipment to manufacture and process long lead-time parts for our automotive customers. The EDC Revolving Facility provides for up to $40 million in borrowings and expires in November 2022. Borrowings under the EDC Revolving Facility bear interest at a LIBOR rate plus a base rate. The EDC Revolving Facility is secured by the assets of Fleetwood Metal Industries Inc. and The Electromac Group Inc. and fully guaranteed by Cliffs. As of December 31, 2020, we had outstanding borrowings on the EDC Revolving Facility of $18 million.

Debt Extinguishment - 2020

During the year ended December 31, 2020, we used the net proceeds from the offering of the additional 9.875% 2025 Senior Secured Notes to repurchase $736 million aggregate principal amount of our outstanding senior notes of various series, which resulted in a net debt reduction of $181 million. We also repurchased an additional $35 million aggregate principal amount of our outstanding senior notes of various series and we redeemed $7 million aggregate principal amount of our outstanding 2020 IRBs, with cash on hand.

Additionally, in connection with the AK Steel Merger, we purchased $364 million aggregate principal amount of 7.625% 2021 AK Senior Notes and $311 million aggregate principal amount of 7.50% 2023 AK Senior Notes upon early settlement of tender offers made by Cliffs. The net proceeds from the offering of 6.75% 2026 Senior Secured Notes, along with a portion of the ABL Facility borrowings, were used to fund such purchases. As the 7.625% 2021 AK Senior Notes and 7.50% 2023 AK Senior Notes were recorded at fair value just prior to being purchased, there was no gain or loss on extinguishment. Additionally, in connection with the final settlement of the tender offers, we purchased $9 million aggregate principal amount of the 7.625% 2021 AK Senior Notes and $56 million aggregate principal amount of the 7.50% 2023 AK Senior Notes with cash on hand.

We intend to use any remaining net proceeds from the underwritten public offering of our common shares following such redemption to reduce borrowings under our ABL Facility. We intend to use the net proceeds from the private notes offering to redeem all of our outstanding 4.875% 2024 Senior Secured Notes, 7.625% 2021 AK Senior Notes, 7.50% 2023 AK Senior Notes, 6.375% 2025 Senior Notes and 6.375% 2025 AK Senior Notes, and pay fees and expenses in connection with such redemptions, and reduce borrowings under our ABL Facility.

NOTE 9 - FAIR VALUE OF FINANCIAL INSTRUMENTS

There were no significant assets or liabilities measured at fair value as of December 31, 2020. The following represents the assets and liabilities measured at fair value as of December 31, 2019:

	(In Millions)

108

The valuation of financial assets classified in Level 2 was determined using a market approach based upon quoted prices for similar assets in active markets, or other inputs that were observable.

Our supply agreement with ArcelorMittal USA contained provisions for supplemental revenue or refunds based on the HRC price in the year the iron ore product was consumed in ArcelorMittal USA’s blast furnaces. We accounted for these provisions as derivative instruments at the time of sale and adjusted the derivative instruments to fair value through Revenues each reporting period until the product was consumed and the amounts were settled. These instruments were classified as Level 3 assets. Upon the completion of the AM USA Transaction, the outstanding derivatives were settled as part of acquisition accounting.

The following tables represent a reconciliation of the changes in fair value of financial instruments measured at fair value on a recurring basis using significant unobservable inputs (Level 3):

	(In Millions)

The carrying values of certain financial instruments (e.g. Accounts receivable, net, Accounts payable and Other current liabilities) approximate fair value and, therefore, have been excluded from the table below. A summary of the carrying value and fair value of other financial instruments were as follows:

The fair value of both current and long-term debt was determined using quoted market prices.

NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans to a significant portion of our employees and retirees. Benefits are also provided through multiemployer plans for certain union members.

As a result of the acquisitions of AK Steel and ArcelorMittal USA, we assumed the obligations under their defined benefit pension plans, OPEB plans, defined contribution plans and commitments to multiemployer pension plans according to collective bargaining agreements that cover certain union-represented employees. The AK Steel defined benefit pension plans and OPEB plans acquired amounted to a benefit obligation, net of assets of $949 million based on a March 13, 2020 measurement. The ArcelorMittal USA defined benefit pension plans and OPEB plans acquired amounted to a benefit obligation, net of assets of $3,294 million based on a December 9, 2020 measurement.

Defined Benefit Pension Plans

The defined benefit pension plans are largely noncontributory and limited in participation. Most plans are closed to new participants with only the legacy iron ore hourly and salaried plans still open. The pension benefit

109

calculations vary by plan, but are generally based on employee's years of service and compensation or a fixed rate and years of service. Certain salaried plans calculate benefits using a cash balance formula, which earns interest credits and allocations based on a percent of pay.

OPEB Plans

We offer postretirement health care and life insurance benefits to retirees through various plans. The vast majority of our plans are closed to new participants. In lieu of retiree medical coverage, many union-represented employees receive a 401(k) contribution per hour worked to a restricted Retiree Health Care Account. Cost sharing features between the employer and retiree vary by plan and several plans include employer caps. Retiree healthcare coverage is provided through programs administered by insurance companies whose charges are based on benefits paid. Certain labor agreements require the funding of VEBAs, which, depending on funding levels, may be used to reimburse the employer for paid benefits.

Contributions

Annual contributions to the pension plans are made within income tax deductibility restrictions in accordance with statutory regulations. OPEB plans are not subject to minimum regulatory funding requirements, but rather amounts are contributed pursuant to bargaining agreements.

1 Pursuant to the applicable bargaining agreements, benefits can be paid from certain VEBAs that are at least 70% funded (all VEBAs are over 70% funded at December 31, 2020). Certain agreements with plans holding VEBA assets have capped healthcare costs. For the ArcelorMittal USA VEBA, depending on funding levels and/or Company profits, we may withdraw money from the VEBA plans to the extent funds are available for costs in excess of the cap. The 2021 expected pension contributions include $118 million in deferred 2020 pension contributions in connection with the CARES Act that were paid on January 4, 2021.

Assumptions

The discount rates used to measure plan liabilities as of the December 31 measurement date are determined individually for each plan. The discount rates are determined by matching the projected cash flows used to determine the plan liabilities to a projected yield curve of high-quality corporate bonds available at the measurement date. Discount rates for expense are calculated using the granular approach for each plan.

Depending on the plan, we use either company-specific base mortality tables or tables issued by the Society of Actuaries. We adopted the Pri-2012 mortality tables from the Society of Actuaries in 2019. On December 31, 2020, the assumed mortality improvement projection was updated from generational scale MP-2019 to generational scale MP-2020 for the Pri-2012 mortality tables.

Plan Assets

Our financial objectives with respect to our pension and VEBA assets are to fully fund the actuarial accrued liability for each of the plans, to maximize investment returns within reasonable and prudent levels of risk, and to maintain sufficient liquidity to meet benefit obligations on a timely basis.

Our investment objective is to outperform the expected return on assets assumption used in the plans’ actuarial reports over the life of the plans. The expected return on assets takes into account historical returns and estimated future long-term returns based on capital market assumptions applied to the asset allocation strategy. The expected return is net of investment expenses paid by the plans. In addition, investment performance is monitored on a quarterly basis by benchmarking to various indices and metrics for the one-, three- and five-year periods.

The asset allocation strategy is determined through a detailed analysis of assets and liabilities by plan, which defines the overall risk that is acceptable with regard to the expected level and variability of portfolio returns, surplus (assets compared to liabilities), contributions and pension expense.

    The asset allocation review process involves simulating capital market behaviors including global asset class performance, inflation and interest rates in order to evaluate various asset allocation scenarios and determine the asset mix with the highest likelihood of meeting financial objectives. The process includes factoring in the current funded status and likely future funded status levels of the plans by taking into account expected growth or decline in the contributions over time.

The asset allocation strategy varies by plan. The following table reflects the actual asset allocations for pension and VEBA assets as of December 31, 2020 and 2019, as well as the 2021 weighted average target asset allocations. Equity investments include securities in large-cap, mid-cap and small-cap companies located in the U.S. and worldwide. Fixed income investments primarily include corporate bonds and government debt securities.

As a practical expedient, in accordance with ASC 820-10, certain investments that are measured at fair value using the NAV per share have not been classified in the fair value hierarchy below. NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by its number of shares outstanding.

The fair value of our pension assets by asset category is as follows:

Following is a description of the inputs and valuation methodologies used to measure the fair value of our plan assets.

Equity Securities

Equity securities classified as Level 1 investments include U.S. large-, small- and mid-cap investments and international equities. These investments are comprised of securities listed on an exchange, market or automated quotation system for which quotations are readily available. The valuation of these securities is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets.

Fixed Income

Fixed income securities classified as Level 1 investments include bonds, government debt securities and cash equivalents. These investments are comprised of securities listed on an exchange, market or automated

116

quotation system for which quotations are readily available. The valuation of these securities is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets. Also included in fixed income is a portfolio of U.S. Treasury STRIPS, which are zero-coupon bearing fixed income securities backed by the full faith and credit of the U.S. government. The securities sell at a discount to par because there are no incremental coupon payments. STRIPS are not issued directly by the Treasury, but rather are created by a financial institution, government securities broker or government securities dealer. Liquidity on the issue varies depending on various market conditions; however, in general, the STRIPS market is slightly less liquid than that of the U.S. Treasury Bond market. The STRIPS are priced daily through a bond pricing vendor and are classified as Level 2.

Hedge Funds

Hedge funds are alternative investments comprised of direct or indirect investment in offshore hedge funds with an investment objective to achieve equity-like returns with one half the volatility of equities and moderate correlation. The valuation techniques used to measure fair value attempt to maximize the use of observable inputs and minimize the use of unobservable inputs. Considerable judgment is required to interpret the factors used to develop estimates of fair value. Valuations of the underlying investment funds are obtained and reviewed. The securities that are valued by the funds are interests in the investment funds and not the underlying holdings of such investment funds. Thus, the inputs used to value the investments in each of the underlying funds may differ from the inputs used to value the underlying holdings of such funds. Hedge funds are valued monthly and recorded on a one-month lag.

Private Equity Funds

Private equity funds are alternative investments that represent direct or indirect investments in partnerships, venture funds or a diversified pool of private investment vehicles (fund of funds).

Investment commitments are made in private equity funds based on an asset allocation strategy, and capital calls are made over the life of the funds to fund the commitments. As of December 31, 2020, remaining commitments total $86 million for our pension and OPEB plans. Committed amounts are funded from plan assets when capital calls are made. Investment commitments are not pre-funded in reserve accounts.

Private equity investments are valued quarterly and recorded on a one-quarter lag. For private equity investment values reported on a lag, current market information is reviewed for any material changes in values at the reporting date. Capital distributions for the funds do not occur on a regular frequency. Liquidation of these investments would require sale of the partnership interest.

Structured Credit

Structured credit funds provide flexibility and access to both complex and illiquid premiums by investing across global, public and private residential, commercial, corporate and specialty credit markets that are priced based on valuations provided by independent, third-party pricing agents, if available. Such values generally reflect the last reported sales price if the security is actively traded. The third-party pricing agents may also value structured credit investments at an evaluated bid price by employing methodologies that utilize actual market transactions, broker-supplied valuations or other methodologies designed to identify the market value of such securities.

Structured credit investments are valued monthly and certain funds have an initial lock-up period and withdrawal restrictions on a semi-annual and quarterly basis. For structured credit investment values reported on a lag, current market information is reviewed for any material changes in values at the reporting date.

Real Estate

The real estate portfolio for the pension plans is an alternative investment comprised of funds with strategic categories of real estate investments. All real estate holdings are appraised externally at least annually, and appraisals are conducted by reputable, independent appraisal firms that are members of the Appraisal Institute. All external appraisals are performed in accordance with the Uniform Standards of Professional Appraisal Practices. The property valuations and assumptions about each property are reviewed quarterly by the investment manager and values are adjusted if there has been a significant change in circumstances relating to the property since the last external appraisal. The fair values of the funds are updated on either a monthly or quarterly basis. Redemption requests are considered on a quarterly basis, subject to notice requirements.

The real estate fund of funds investment for the Empire-Tilden, Hibbing and United Taconite VEBA plans invests in pooled investment vehicles that, in turn, invest in commercial real estate properties. Valuations are performed quarterly and financial statements are prepared on a semi-annual basis, with annual audited statements.

117

Asset values for this fund are reported with a one-quarter lag, and current market information is reviewed for any material changes in values at the reporting date. Withdrawals are permitted on the last business day of each quarter subject to a 95-day prior written notice.

Absolute Return Fixed Income

Absolute return fixed income investments consist of a global fixed income fund with the investment objective of generating positive absolute returns over a full market cycle. The fund's investments in securities, forward exchange contracts and futures contracts are reported at fair value on a recurring monthly basis. The fund's trustee values securities based upon independent pricing sources and futures contracts are valued at closing settled prices. Redemptions of the fund at NAV are permitted monthly under most circumstances.

Defined Contribution Plans

Most employees are eligible to participate in various defined contribution plans. Certain of these plans have features with matching contributions or other Company contributions based on our financial results. Company contributions to these plans are expensed as incurred. Total expense from these plans was $22 million, $3 million and $3 million in 2020, 2019 and 2018, respectively.

Multiemployer Plans

We contribute to multiemployer pension plans according to collective bargaining agreements that cover certain union-represented employees. The following risks of participating in these multiemployer plans differ from single employer pension plans:

•Employer contributions to a multiemployer plan may be used to provide benefits to employees of other participating employers.

•If a participating employer stops contributing to a multiemployer plan, the remaining participating employers may need to assume the unfunded obligations of the plan.

•If the multiemployer plan becomes significantly underfunded or is unable to pay its benefits, we may be required to contribute additional amounts in excess of the rate required by the collective bargaining agreements.

•If we choose to stop participating in a multiemployer plan, we may be required to pay that plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

We are a party to five collective bargaining agreements at our Ashland Works, Mansfield Works, United Taconite, Tubular Components and the majority of our ArcelorMittal USA locations that require contributions to the Steelworkers Pension Trust.

We are a party to three collective bargaining agreements at Butler Works, Middletown Works and Zanesville Works that require contributions to the International Association of Machinists and Aerospace Workers ("IAM") National Pension Fund's National Pension Plan. The plan voluntarily elected to place itself in the "Red Zone" in April 2019 and has implemented a rehabilitation plan. Additional contributions will be required as part of the rehabilitation plan until the plan exits the critical status.

(a) The most recent Pension Protection Act zone status available in 2020 and 2019 is for each plan's year-end at December 31, 2019 and 2018. The plan's actuary certifies the zone status. Generally, plans in the red zone are less than 65% funded, plans in the yellow zone are between 65% and 80% funded, and plans in the green zone are at least 80% funded.
(b) The "FIP/RP Status Pending/Implemented" column indicates plans for which a financial improvement plan or a rehabilitation plan is either pending or has been implemented, as defined by ERISA.
(c) The surcharge represents an additional required contribution due as a result of the critical funding status of the plan.

Prior to the Acquisitions, AK Steel and ArcelorMittal USA made up over 30% of the contributions to the Steelworkers Pension Trust in the last three years. Only two other employers contributed more than 5% during this period. As of December 31, 2019 (the last date for which we have information), the Steelworkers Pension Trust had a total actuarial liability of $5,748 million and assets with a market value of $5,372 million, for a funded ratio of about 93%.

NOTE 11 - STOCK COMPENSATION PLANS

At December 31, 2020, we had outstanding awards under two share-based compensation plans: the A&R 2015 Equity Plan and the 2012 Amended Equity Plan. On March 13, 2020, the maximum number of shares that may be issued under the A&R 2015 Equity Plan increased by 5.7 million common shares in relation to the outstanding AK Steel stock-based incentive awards that we converted at a 0.400 rate of exchange. The converted stock-based incentive awards include 2.0 million stock options, 1.0 million long-term performance plan awards, 0.5 million performance shares, 0.2 million restricted stock awards and 0.3 million restricted stock units. As of December 31, 2020, there were 4.9 million remaining shares available for grant under the A&R 2015 Equity Plan. No additional grants were issued from the 2012 Amended Equity Plan after the date of approval of the A&R 2015 Equity Plan; however, all awards previously granted under the 2012 Amended Equity Plan will continue in accordance with the terms of the outstanding awards.

The 2.5 million awards granted in 2020 include 1.0 million long-term performance plan awards and 0.5 million performance shares relating to the AK Steel replacement awards. As of December 31, 2020, 0.3 million long-term performance plan awards and 0.1 million performance shares were outstanding as a result of qualifying termination events that triggered accelerated performance share payouts and prorated long-term performance plan awards payouts at target. The long-term performance plan awards are based on a three-year Adjusted EBITDA metric. The weighted average grant date fair value for the converted performance awards was $4.59 per share.

The outstanding performance shares vest over a period of three years and are intended to be paid out in common shares. Performance is measured on the basis of relative TSR for the period and measured against the constituents of the S&P Metals and Mining ETF Index. The number of shares actually earned at the end of the three-year period will vary, based on performance, from 0% to 200% of the number of performance shares granted.

Stock options granted to date generally vest over a period from one to three years with an expiration date at ten years from the date of grant. On March 13, 2020, we granted 2.0 million options as AK Steel replacement awards. The weighted average fair value of the converted options was $0.51 per share and was calculated using the Black-Scholes option-pricing model. Qualifying termination events resulted in vest date accelerations and reductions to the option expiration date from ten years to three years.

The total intrinsic value of options exercised in 2020 and 2018 were immaterial. For options outstanding at December 31, 2020, the weighted-average remaining contractual life was 3.2 years and the aggregate intrinsic value was $11 million. For options exercisable at December 31, 2020, the weighted-average remaining contractual life was 2.5 years and the aggregate intrinsic value was $9 million.

Nonemployee Directors

Our nonemployee directors are entitled to receive restricted share awards under the Directors’ Plan. For 2020, 2019 and 2018, nonemployee directors were granted a specified number of restricted shares, with a value equal to $100,000. The number of shares is based on the closing price of our common shares on the date of the Annual Meeting. The restricted share awards issued under the Directors' Plan generally vest 12 months from the grant date. The awards are subject to any deferral election and the terms of the Directors’ Plan and an award agreement.

On March 13, 2020, 0.3 million restricted stock units previously awarded to the members of the AK Steel board of directors were distributed per the terms of the AK Steel Merger Agreement.

For the last three years, grants of restricted and/or deferred shares have been awarded to elected or re-elected nonemployee directors as follows:

Year of Grant	Restricted Shares	Deferred Shares
2020	253,809	54,794
2019	86,477	23,659

The increase in income tax benefit from 2019 to 2020 is directly correlated to the increase in pre-tax book loss from the prior period for both federal and state income tax purposes. The other primary driver of the increase in income tax benefit is related to income of noncontrolling interests for which no tax is recognized.

The increase in income tax expense from 2018 to 2019 is primarily due to release of the valuation allowance in the U.S. of $461 million in 2018, which did not recur in 2019. The Luxembourg legal entity reduction relates to initiatives resulting in the dissolution of certain entities and settlement of related financial instruments in the years ended December 31, 2019 and 2018. These 2019 and 2018 NOL deferred tax asset reductions resulted in tax expense of $846 million and $162 million, respectively, which were fully offset by decreases in the respective valuation allowance.

We had gross domestic (including states) and foreign NOLs of $7,444 million and $1,592 million, respectively, at December 31, 2020. We had gross domestic and foreign NOLs of $3,459 million and $1,592 million, respectively, at December 31, 2019. The U.S. federal NOLs will begin to expire in 2034 and state NOLs will begin to expire in 2021. The foreign NOLs can be carried forward indefinitely. We had foreign tax credit carryforwards of $6 million at December 31, 2019, which expired in 2020. We had gross interest expense limitation carryforwards of $80 million and $55 million for the years ended December 31, 2020 and 2019, respectively. This interest expense can be carried forward indefinitely.

The changes in the valuation allowance are presented below:

	(In Millions)

Balance at beginning of year	$	441	$	1,287	$	1,983

During 2020, we recorded a $398 million valuation allowance through opening balance sheet adjustments to reflect the portion of federal and state NOLs that are limited under Section 382 of the IRC acquired through the AK Steel Merger.

During 2019, a legal entity reduction initiative was completed in Luxembourg resulting in the dissolution of certain entities and settlement of related financial instruments, triggering the utilization of $1.3 billion of NOL deferred tax asset and reversal of the intercompany notes deferred tax liability of $447 million. In addition, prior year adjustments in Luxembourg and a statutory rate reduction from 26.01% to 24.94% resulted in a net increase to the operating loss carryforward deferred tax asset of $46 million. The total net deferred tax reduction resulted in an expense of $846 million which was fully offset by a decrease in the valuation allowance. During 2018, a similar legal entity reduction initiative was completed resulting in the dissolution of certain Luxembourg entities which resulted in a decrease in the NOL deferred tax asset of $162 million which was fully offset by a decrease in valuation allowance. We continue to maintain a full valuation allowance against the remaining Luxembourg net deferred tax assets of $397 million at December 31, 2020 and 2019. Our losses in Luxembourg in recent periods represent sufficient negative evidence to require a full valuation allowance against the deferred tax assets in that jurisdiction. We intend

124

to maintain a valuation allowance against the deferred tax assets related to these operating losses, until sufficient positive evidence exists to support the realization of such assets.

We recorded a $696 million net decrease in the valuation allowance in the year ended December 31, 2018. As of December 31, 2018, our U.S. operations emerged from a three-year cumulative loss position. As the significant negative evidence of cumulative losses had been eliminated, we undertook an evaluation of the continuing need for a valuation allowance on the U.S. deferred tax assets, the majority of which related to the U.S. tax NOLs.

In completing our evaluation of whether a valuation allowance was still needed, we considered all available positive and negative evidence. Positive evidence considered included the emergence from the three-year cumulative loss position, our long-term customer contracts with minimum tonnage requirements, the global scarcity of iron ore pellets, near term forecasts of strong profitability and the recently revised IRC Section 163(j) interest deduction limitation. Negative evidence included the overall size of the deferred tax asset with limited carryforward and no carryback opportunity, the finite nature of the iron ore resources we mine, the uncertainty of steel tariffs that positively impacted our revenue rates in 2018 and the various market signs that the U.S. economy may be nearing the end of the current expansion.

We also considered that future realization of the deferred tax assets depends on the existence of sufficient taxable income of the appropriate character during the carryforward period. In considering sources of taxable income, we identified that a portion of the deferred tax assets would be utilized by existing taxable temporary differences reversing in the same periods as existing deductible temporary differences. In addition, we determined that carryback opportunities and tax planning strategies do not exist as potential sources of future taxable income. Lastly, forecasting future taxable income was considered, but was challenging in a cyclical industry such as ours as it relies heavily on the accuracy of key assumptions, particularly about key pricing benchmarks.

Because historical information is verifiable and more objective than forecast information and due to the cyclicality of the industry, we developed an estimate of future income based on our historical earnings through the most recent industry cycle. We adjusted historical earnings for certain non-recurring items as well as to reflect the current corporate structure by eliminating the impact of discontinued operations and extinguished debt (“core earnings”). Additionally, we adjusted core earnings to reflect the impact of the recently revised IRC Section 163(j) interest expense deduction limitation as well as permanent tax adjustments. The IRC Section 163(j) limitation would limit our interest expense deduction, particularly in down years in the industry cycle, resulting in higher taxable income.

Based on the core earnings analysis, our average annual book taxable income through the business cycle was in excess of the estimated $10 million taxable income that would be required annually to fully utilize the deferred tax assets within the 19-year carryforward period. We ascribed significant weight in our assessment to the core earnings analysis and the resulting projection of taxable income through the industry cycle. Based on the weight of this positive evidence, and after considering the other available positive and negative evidence, we determined that it was appropriate to release all of the valuation allowance related to U.S. federal deferred tax assets at December 31, 2018 as it was more likely than not that the entire amount of the U.S. deferred tax asset would be realized before the end of the carryforward period. The income tax benefit recorded for the reversal of the valuation allowance against the U.S. deferred tax assets was $461 million for the year ended December 31, 2018.

We also have a valuation allowance recorded against certain state NOLs and foreign tax credits, which are expected to expire before utilization. At December 31, 2020 and 2019, we had a valuation allowance recorded against certain state NOLs of $98 million and $38 million, respectively. At December 31, 2019, we had a valuation allowance recorded against certain foreign tax credits of $6 million, which expired in 2020.

At December 31, 2020 and 2019, we had no cumulative undistributed earnings of foreign subsidiaries included in retained earnings. Accordingly, no provision has been made for U.S. deferred taxes related to future repatriation of earnings.

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

	(In Millions)
	2020		2019		2018
Unrecognized tax benefits balance as of January 1	$	29	$	29	$	33

Increases from acquisitions	75		—		—
Unrecognized tax benefits balance as of December 31	$	107	$	29	$	29

At December 31, 2020 and 2019, we had $107 million and $29 million, respectively, of unrecognized tax benefits recorded. Of this amount, $9 million was recorded in Other current liabilities for the year ended December 31, 2020. Additionally, $2 million and $4 million, were recorded in Other non-current liabilities for the years ended December 31, 2020 and 2019, respectively, and $96 million was recorded in Other non-current assets for both years in the Statements of Consolidated Financial Position. If the unrecognized tax benefits were recognized, the entire $11 million would impact the effective tax rate. We do not expect that the amount of unrecognized benefits will change significantly within the next 12 months. At December 31, 2020 and 2019, we had $1 million and $4 million, respectively, of accrued interest and penalties related to the unrecognized tax benefits recorded in Other non-current liabilities in the Statements of Consolidated Financial Position.

Tax years 2016 and forward remain subject to examination for the U.S., and tax years 2008 and forward remain subject to examination for Canada.

NOTE 13 - LEASE OBLIGATIONS

Our operating leases consist primarily of leases for office space, iron ore vessels, rail cars, processing equipment and mining equipment. Our finance leases consist primarily of processing equipment and mining equipment. We use our incremental borrowing rate as the discount rate to determine the present value of the lease payments, as our leases do not have readily determinable implicit discount rates. Our incremental borrowing rate is the rate of interest that we would have to borrow on a collateralized basis over a similar term and amount in a similar economic environment to pay our lease obligations. We determine the incremental borrowing rates for our leases by adjusting the local risk-free interest rate with a credit risk premium corresponding to our credit rating. From time to time, we may enter into arrangements for the construction or purchase of an asset and then enter into a financing arrangement to lease the asset. We recognize leased assets and liabilities under these arrangements when we obtain control of the asset.

NOTE 14 - ASSET RETIREMENT OBLIGATIONS

The following is a summary of our asset retirement obligations:

Asset retirement obligations1	$	342	$	165
Less: current portion	7		2
Long-term asset retirement obligations	$	335	$	163
1 Includes $190 million and $22 million related to our active operations as of December 31, 2020 and 2019, respectively.

The accrued closure obligation provides for contractual and legal obligations related to our indefinitely idled and closed operations and for the eventual closure of our active operations. We performed a detailed assessment of our asset retirement obligations related to our active operations most recently in 2020 in accordance with our

127

accounting policy, which requires us to perform an in-depth evaluation of the liability every three years in addition to routine annual assessments. In 2020, we employed third-party specialists to assist in the evaluation.

Additionally, we have included in our asset retirement obligation $172 million for our integrated steel facilities and other operations acquired in the Acquisitions. The closure date for each of our active mine sites was determined based on the exhaustion date of the remaining mineral reserves and the amortization of the related asset and accretion of the liability is recognized over the estimated mine lives. The closure date and expected timing of the capital requirements to meet our obligations for our indefinitely idled or closed mines is determined based on the unique circumstances of each property. For indefinitely idled or closed mines, the accretion of the liability is recognized over the anticipated timing of remediation. As the majority of our asset retirement obligations at our steelmaking operations have indeterminate settlement dates, asset retirement obligations have been recorded at present values using estimated ranges of the economic lives of the underlying assets.

The following is a roll-forward of our asset retirement obligation liability:

	(In Millions)
	2020		2019
Asset retirement obligation as of January 1	$	165	$	172
Increase from acquisitions	172		—
Accretion expense	14		10
Remediation payments	(9)		(1)
Revision in estimated cash flows	—		(16)
Asset retirement obligation as of December 31	$	342	$	165

The revision in estimated cash flows during the year ended December 31, 2019 for $16 million primarily relates to an extension of the life-of-mine plan for Tilden mine based on the economic reserve analysis performed during 2019.

NOTE 15 - DERIVATIVE INSTRUMENTS

Derivatives Not Designated as Hedging Instruments

Customer Supply Agreement

A supply agreement with ArcelorMittal USA provided us supplemental revenue or provided refunds to ArcelorMittal USA based on the HRC price at the time the iron ore product was consumed in its blast furnaces. The supplemental pricing is characterized as a freestanding derivative instrument and is required to be accounted for separately once control transfers to the customer. The derivative instrument, which is finalized based on a future price, is adjusted to fair value through Revenues each reporting period based upon current market data and forward-looking estimates provided by management until the pellets are consumed and the amounts are settled. Upon the completion of the AM USA Transaction, the outstanding derivatives were settled as part of acquisition accounting. Included within Revenues related to Topic 815 for the supplemental revenue portion of the supply agreement is derivative revenue of $122 million, $78 million and $426 million for the years ended December 31, 2020, 2019 and 2018, respectively.

NOTE 16 - CAPITAL STOCK

Acquisition of AK Steel

As more fully described in NOTE 3 - ACQUISITIONS, we acquired AK Steel on March 13, 2020. At the effective time of the AK Steel Merger, each share of AK Steel common stock issued and outstanding prior to the effective time of the AK Steel Merger was converted into, and became exchangeable for, 0.400 Cliffs common shares, par value $0.125 per share. We issued a total of 127 million Cliffs common shares in connection with the AK Steel Merger at a fair value of $618 million. Following the closing of the AK Steel Merger, AK Steel's common stock was de-listed from the NYSE.

128

Acquisition of ArcelorMittal USA

As more fully described in NOTE 3 - ACQUISITIONS, we acquired ArcelorMittal USA on December 9, 2020. Pursuant to the terms of the AM USA Transaction Agreement, we issued 78,186,671 common shares and 583,273 shares of a new series of our Serial Preferred Stock, Class B, without par value, designated as the “Series B Participating Redeemable Preferred Stock,” in each case to an indirect, wholly owned subsidiary of ArcelorMittal as part of the consideration paid by us in connection with the closing of the AM USA Transaction. Refer to Preferred Stock below for further information.

Preferred Stock

We have 3,000,000 shares of Serial Preferred Stock, Class A, without par value and 4,000,000 shares of Serial Preferred Stock, Class B, without par value, authorized; no Class A preferred shares are issued or outstanding. Pursuant to the terms of the AM USA Transaction Agreement, we issued 583,273 shares of a new series of our Serial Preferred Stock, Class B, without par value, designated Series B Participating Redeemable Preferred Stock, without par value, to an indirect, wholly owned subsidiary of ArcelorMittal on December 9, 2020.

Series B Participating Redeemable Preferred Stock Terms

The Series B Participating Redeemable Preferred Stock is classified for accounting purposes as temporary equity as a result of a change in control provision that could, under remote circumstances, require us to redeem the preferred stock for cash.

The Series B Participating Redeemable Preferred Stock ranks senior to our common shares with respect to dividend rights and rights on the distribution of assets upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of, and certain bankruptcy events involving, Cliffs. Each share of Series B Participating Redeemable Preferred Stock entitles its holder to receive a multiple, initially equal to 100 (subject to certain anti-dilution adjustments, the “Applicable Multiple”), of the aggregate amount per share of all dividends declared on the common shares. In addition, from and after the 24-month anniversary of the issue date of the Series B Participating Redeemable Preferred Stock (the “24-Month Anniversary”), each holder of a share of Series B Participating Redeemable Preferred Stock is entitled to receive cash dividends (the “Additional Dividends”) accruing and compounding on a daily basis at the initial rate of 10% per annum on the sum of (i) the Applicable Multiple then in effect times the volume-weighted average price of the common shares for the 20 consecutive trading days ending on the trading day immediately preceding the 24-Month Anniversary and (ii) the amount of accumulated and unpaid dividends on the Series B Participating Redeemable Preferred Stock to, but not including, the 24-Month Anniversary, if any, which rate will increase by 2% per annum at the end of each six-month period following the 24-Month Anniversary. Additional Dividends will be payable, when, as and if declared by the Board, in quarterly installments.

The Series B Participating Redeemable Preferred Stock is redeemable, in whole or in part, at our option at any time and from time to time on and after the date that is 180 days after the issue date at a redemption price per share equal to the Applicable Multiple then in effect times the volume-weighted average price of the common shares for the 20 consecutive trading days ending on the trading day immediately preceding the date fixed for redemption, plus accumulated and unpaid dividends to, but not including, the redemption date.

In the event of a change of control of Cliffs, the Series B Participating Redeemable Preferred Stock will be subject to mandatory redemption at a redemption price per share equal to the Applicable Multiple then in effect times the volume-weighted average price of the common shares for the 20 consecutive trading days ending on the trading day immediately preceding the closing date of the transaction constituting such change of control.

In addition, pursuant to the terms of the Series B Participating Redeemable Preferred Stock, we are restricted from effecting any merger or consolidation with or into another entity unless the Series B Participating Redeemable Preferred Stock remains outstanding following the merger or consolidation, is exchanged for new preferred stock with substantially identical terms or is to be redeemed in connection with the closing of such merger or consolidation.

In addition to the foregoing, the Series B Participating Redeemable Preferred Stock is subject to the express terms of the Serial Preferred Stock, Class B, without par value, as set forth in Cleveland-Cliffs Inc.’s Fourth Amended Articles of Incorporation, as amended, except that holders of Series B Participating Redeemable Preferred Stock, in their capacity as such, do not have the right to vote with the other series of Serial Preferred Stock, Class B, without par value, then outstanding, if any, voting separately as a class, for the election of additional directors of Cleveland-Cliffs Inc. upon certain defaults by the Company in the payment of dividends, as provided in Cleveland-Cliffs Inc.’s Fourth Amended Articles of Incorporation, as amended.

1 The dividend declared on September 3, 2019 included a special cash dividend of $0.04 per common share.

Subsequent to the dividend paid on April 15, 2020, our Board temporarily suspended future dividends as a result of the COVID-19 pandemic in order to preserve cash during this time of economic uncertainty.

Share Repurchase Program

In November 2018, we announced that our Board of Directors authorized a program to repurchase outstanding common shares in the open market or in privately negotiated transactions, up to a maximum of $200 million, excluding commissions and fees. In April 2019, we announced that our Board of Directors increased the common share repurchase authorization by an additional $100 million, excluding commissions and fees. During 2019, we repurchased 24 million common shares at a cost of $253 million in the aggregate, including commissions and fees. The share repurchase program was effective until December 31, 2019.

Our supply agreement with ArcelorMittal USA contained provisions that provided us supplemental revenue or provided refunds to ArcelorMittal USA based on the HRC price at the time the iron ore product was consumed in its blast furnaces. The supplemental pricing was categorized as a freestanding derivative. Upon the completion of the AM USA Transaction, the outstanding derivative was settled as part of acquisition accounting.

NOTE 19 - VARIABLE INTEREST ENTITIES

SunCoke Middletown

We purchase all the coke and electrical power generated from SunCoke Middletown’s plant under long-term supply agreements and have committed to purchase all the expected production from the facility through 2032. We consolidate SunCoke Middletown as a VIE because we are the primary beneficiary despite having no ownership interest in SunCoke Middletown. SunCoke Middletown had income before income taxes of $41 million for the year ended December 31, 2020, which was included in our consolidated income before income taxes.

NOTE 21 - COMMITMENTS AND CONTINGENCIES

Purchase Commitments

We purchase portions of the principal raw materials required for our steel manufacturing operations under annual and multi-year agreements, some of which have minimum quantity requirements. We also use large volumes of natural gas, electricity and industrial gases in our steel manufacturing operations. We negotiate most of our purchases of chrome, industrial gases and a portion of our electricity under multi-year agreements. Our purchases of coke are made under annual or multi-year agreements with periodic price adjustments. We typically purchase coal under annual fixed-price agreements. We also purchase certain transportation services under multi-year contracts with minimum quantity requirements.

Contingencies

We are currently the subject of, or party to, various claims and legal proceedings incidental to our current and historical operations. These claims and legal proceedings are subject to inherent uncertainties and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, additional funding requirements or an injunction. If an unfavorable ruling were to occur, there exists the possibility of a material adverse effect on the financial position and results of operations for the period in which the ruling occurs or future periods. However, based on currently available information we do not believe that any pending claims or legal proceedings will result in a material adverse effect in relation to our consolidated financial statements.

Environmental Contingencies

Although we believe our operating practices have been consistent with prevailing industry standards, hazardous materials may have been released at operating sites or third-party sites in the past, including operating sites that we no longer own. If we reasonably can, we estimate potential remediation expenditures for those sites where future remediation efforts are probable based on identified conditions, regulatory requirements, or contractual obligations arising from the sale of a business or facility. For sites involving government required investigations, we typically make an estimate of potential remediation expenditures only after the investigation is complete and when we better understand the nature and scope of the remediation. In general, the material factors in these estimates include the costs associated with investigations, delineations, risk assessments, remedial work, governmental response and oversight, site monitoring, and preparation of reports to the appropriate environmental agencies.

The following is a summary of our environmental obligations:

	(In Millions)
	December 31, 2020		December 31, 2019
Environmental obligations	$	135	$	2
Less current portion	18		—
Long-term environmental obligations	$	117	$	2

We cannot predict the ultimate costs for each site with certainty because of the evolving nature of the investigation and remediation process. Rather, to estimate the probable costs, we must make certain assumptions. The most significant of these assumptions is for the nature and scope of the work that will be necessary to investigate and remediate a particular site and the cost of that work. Other significant assumptions include the cleanup technology that will be used, whether and to what extent any other parties will participate in paying the investigation and remediation costs, reimbursement of past response costs and future oversight costs by governmental agencies, and the reaction of the governing environmental agencies to the proposed work plans. Costs for future investigation

134

and remediation are not discounted to their present value, unless the amount and timing of the cash disbursements are readily known. To the extent that we have been able to reasonably estimate future liabilities, we do not believe that there is a reasonable possibility that we will incur a loss or losses that exceed the amounts we accrued for the environmental matters discussed below that would, either individually or in the aggregate, have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, since we recognize amounts in the consolidated financial statements in accordance with GAAP that exclude potential losses that are not probable or that may not be currently estimable, the ultimate costs of these environmental matters may be higher than the liabilities we currently have recorded in our consolidated financial statements.

Pursuant to RCRA, which governs the treatment, handling and disposal of hazardous waste, the EPA and authorized state environmental agencies may conduct inspections of RCRA-regulated facilities to identify areas where there have been releases of hazardous waste or hazardous constituents into the environment and may order the facilities to take corrective action to remediate such releases. Likewise, the EPA or the states may require closure or post-closure care of residual, industrial and hazardous waste management units, including, but not limited to, landfills and deep injection wells. Environmental regulators have the authority to inspect all of our facilities. While we cannot predict the future actions of these regulators, it is possible that they may identify conditions in future inspections of these facilities that they believe require corrective action.

Pursuant to CERCLA, the EPA and state environmental authorities have conducted site investigations at some of our facilities and other third-party facilities, portions of which previously may have been used for disposal of materials that are currently regulated. The results of these investigations are still pending, and we could be directed to spend funds for remedial activities at the former disposal areas. Because of the uncertain status of these investigations, however, we cannot reasonably predict whether or when such spending might be required or its magnitude.

On April 29, 2002, AK Steel entered a mutually agreed-upon administrative order with the consent of the EPA pursuant to Section 122 of CERCLA to perform a RI/FS of the Hamilton plant site located in New Miami, Ohio. The plant ceased operations in 1990 and all of its former structures have been demolished. AK Steel submitted the investigation portion of the RI/FS and completed supplemental studies. Until the RI/FS is complete, we cannot reasonably estimate the additional costs, if any, we may incur for potentially required remediation of the site or when we may incur them.

EPA Administrative Order In Re: Ashland Coke

On September 26, 2012, the EPA issued an order under Section 3013 of RCRA requiring a plan to be developed for investigation of four areas at the Ashland Works coke plant. The Ashland Works coke plant ceased operations in 2011 and all of its former structures have been demolished and removed. In 1981, AK Steel acquired the plant from Honeywell International Corporation (as successor to Allied Corporation), who had managed the coking operations there for approximately 60 years. In connection with the sale of the coke plant, Honeywell agreed to indemnify AK Steel against certain claims and obligations that could arise from the investigation, and we intend to pursue such indemnification from Honeywell, if necessary. We cannot reasonably estimate how long it will take to complete the site investigation. On March 10, 2016, the EPA invited AK Steel to participate in settlement discussions regarding an enforcement action. Settlement discussions between the parties are ongoing, though whether the parties will reach agreement and any such agreement’s terms are uncertain. Until the site investigation is complete, we cannot reasonably estimate the costs, if any, we may incur for potential additional required remediation of the site or when we may incur them.

Burns Harbor Water Issues

In August 2019, ArcelorMittal Burns Harbor LLC (n/k/a Cleveland-Cliffs Burns Harbor LLC) suffered a loss of the blast furnace cooling water recycle system, which led to the discharge of cyanide and ammonia in excess of the Burns Harbor plant's NPDES permit limits. Since that time, the facility has taken numerous steps to prevent recurrence and maintain compliance with its NPDES permit. Since the August 2019 event, we have been engaged in settlement discussions with the U.S. Department of Justice, the EPA and the State of Indiana to resolve any alleged violations of environmental laws or regulations. Also, ArcelorMittal Burns Harbor LLC was served with a subpoena on December 5, 2019, from the United States District Court for the Northern District of Indiana relating to the August 2019 event and has responded to the subpoena requests. In addition, the plaintiffs in Environmental Law & Policy Center et al. v. ArcelorMittal Burns Harbor LLC et al. (U.S. District Court, N.D. Indiana Case No. 19-cv-473), which was filed on December 20, 2019, have alleged violations resulting from the August 2019 event and other Clean Water Act claims. Although we cannot accurately estimate the amount of civil penalty, the cost of any injunctive relief requirements, or the costs to resolve third-party claims, including potential natural resource damages claims, they are likely to exceed the reporting threshold in total.

135

In addition to the foregoing matters, we are or may be involved in proceedings with various regulatory authorities that may require us to pay fines, comply with more rigorous standards or other requirements or incur capital and operating expenses for environmental compliance. We believe that the ultimate disposition of any such proceedings will not have, individually or in the aggregate, a material adverse effect on our consolidated financial condition, results of operations or cash flows.

Tax Matters

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. We recognize liabilities for anticipated tax audit issues based on our estimate of whether, and the extent to which, additional taxes will be due. If we ultimately determine that payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary. We also recognize tax benefits to the extent that it is more likely than not that our positions will be sustained when challenged by the taxing authorities. To the extent we prevail in matters for which liabilities have been established, or are required to pay amounts in excess of our liabilities, our effective tax rate in a given period could be materially affected. An unfavorable tax settlement would require use of our cash and result in an increase in our effective tax rate in the year of resolution. A favorable tax settlement would be recognized as a reduction in our effective tax rate in the year of resolution. Refer to NOTE 12 - INCOME TAXES for further information.

Other Contingencies

In addition to the matters discussed above, there are various pending and potential claims against us and our subsidiaries involving product liability, commercial, employee benefits and other matters arising in the ordinary course of business. Because of the considerable uncertainties that exist for any claim, it is difficult to reliably or accurately estimate what the amount of a loss would be if a claimant prevails. If material assumptions or factual understandings we rely on to evaluate exposure for these contingencies prove to be inaccurate or otherwise change, we may be required to record a liability for an adverse outcome. If, however, we have reasonably evaluated potential future liabilities for all of these contingencies, including those described more specifically above, it is our opinion, unless we otherwise noted, that the ultimate liability from these contingencies, individually or in the aggregate, should not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

NOTE 22 - SUBSEQUENT EVENTS

On February 11, 2021, we sold 20 million common shares, and the indirect, wholly owned subsidiary of ArcelorMittal to which approximately 78 million common shares were issued as part of the consideration paid by us in connection with the closing of the AM USA Transaction sold 40 million common shares, in each case at a price per share to the underwriter of $16.12, in an underwritten public offering. We also granted the underwriter an option to purchase up to an additional 9 million common shares from us at a price per share to the underwriter of $16.12. The underwriter has until March 10, 2021 to exercise such option, which it may do in full, in part or not at all. We did not receive any proceeds from the sale of the common shares by the selling shareholder in the offering. We intend to use the net proceeds to us from the offering, plus cash on hand, to redeem up to approximately $334 million aggregate principal amount of our outstanding 9.875% 2025 Senior Secured Notes. We intend to use any remaining net proceeds to us following such redemption to reduce borrowings under our ABL Facility.

On February 9, 2021, following pricing of the underwritten public offering, we issued a conditional notice of partial redemption to holders of the 9.875% 2025 Senior Secured Notes to redeem $322 million aggregate principal amount of the outstanding 9.875% 2025 Senior Secured Notes on March 11, 2021, at a redemption price equal to 109.875% of the principal amount to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. The conditional notice of partial redemption was subject to the condition precedent that we close the underwritten public offering of our common shares. As a result, following the closing of the underwritten public offering, the conditional notice of partial redemption became irrevocable.

On February 17, 2021, we issued $500 million aggregate principal amount of 4.625% 2029 Senior Notes and $500 million aggregate principal amount of 4.875% 2031 Senior Notes in an offering that was exempt from the registration requirements of the Securities Act. We intend to use the net proceeds from the notes offering to redeem all of the outstanding 4.875% 2024 Senior Secured Notes and 6.375% 2025 Senior Notes issued by Cleveland-Cliffs Inc. and all of the outstanding 7.625% 2021 AK Senior Notes, 7.50% 2023 AK Senior Notes and 6.375% 2025 AK Senior Notes issued by AK Steel Corporation (n/k/a Cleveland-Cliffs Steel Corporation), and pay fees and expenses in connection with such redemptions, and reduce borrowings under our ABL Facility.

On February 10, 2021, following pricing of the notes offering, we issued notices of redemption to the holders of the 4.875% 2024 Senior Secured Notes, 6.375% 2025 Senior Notes, 7.625% 2021 AK Senior Notes, 7.50% 2023

AK Senior Notes and 6.375% 2025 AK Senior Notes to redeem all of such notes outstanding on March 12, 2021, at the redemption prices listed below, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. The notices of redemption with respect to the 4.875% 2024 Senior Secured Notes and the 6.375% 2025 Senior Notes were subject to the condition precedent that we close the notes offering. As a result, following the closing of the notes offering, the notices of redemption with respect to the 4.875% 2024 Senior Secured Notes and the 6.375% 2025 Senior Notes became irrevocable. The notices of redemption with respect to the 7.625% 2021 AK Senior Notes, 7.50% 2023 AK Senior Notes and 6.375% 2025 AK Senior Notes were not subject to any conditions and were irrevocable when issued.

Mineral Reserves — Asset Retirement Obligations, Valuation of Long-Lived Assets, Depreciation, Depletion and Amortization of Property, Plant and Equipment and Valuation in Acquisition Accounting —Refer to Notes 3, 5, 6 and 14 to the financial statements

Critical Audit Matter Description

Iron ore mineral reserve estimates, combined with estimated annual production levels, are used to determine the iron ore mine closure dates utilized in recording the fair value liability for asset retirement obligations for active operating iron ore mines. Since the liability represents the present value of the expected future obligation, a significant change in iron ore mineral reserves or iron ore mine lives could have a substantial effect on the recorded obligation. Iron ore mineral reserve estimates are also used in evaluating potential impairments of iron ore mine asset groups as they are indicative of future cash flows and in determining maximum useful lives utilized to calculate depreciation, depletion and amortization of long-lived iron ore mine assets. Further, iron ore mineral reserve estimates are used in estimating the fair value of mineral reserves established through the purchase price allocation in a business combination. The Company performs an in-depth evaluation of its iron ore mineral reserve estimates by iron ore mine on a periodic basis, in addition to routine annual assessments. The determination of iron ore mineral reserves requires management, with the support of management’s experts, to make significant estimates and assumptions related to

138

key inputs including (1) the determination of the size and scope of the iron ore body through technical modeling, (2) the estimates of future iron ore prices recognizing that the price shall not exceed the three-year trailing average index price of iron ore adjusted to the Company’s realized price, production costs and capital expenditures, and (3) management’s mine plan for the proven and probable iron ore mineral reserves (collectively “the iron ore mineral reserve inputs”). Changes in any of the judgments or assumptions related to the iron ore mineral reserve inputs can have a significant impact with respect to the accrual for asset retirement obligations, the impairment of long-lived asset groups, the amount of depreciation, depletion and amortization expense and the estimated fair value of mineral reserves established through the purchase price allocation in a business combination. The consolidated asset retirement obligation balance was $342 million as of December 31, 2020, of which $83 million related to active iron ore mine operations. The total asset balance associated with the Company’s Steelmaking reportable segment was $15,849 million as of December 31, 2020, of which $1,661 million related to long-lived assets associated with the Company’s combined iron ore mine asset groups, and is inclusive of $235 million related to iron ore mineral reserves acquired through the AM USA Transaction. Depreciation, depletion and amortization expense for the Company’s combined iron ore mine asset groups was $78 million for the year ended December 31, 2020.

Given the significant judgments and assumptions made by management to estimate iron ore mineral reserves and the sensitivity of changes to iron ore mineral reserve estimates on the Company’s recorded asset retirement obligations, long-lived asset impairment considerations, calculated depreciation, depletion and amortization expense and estimated fair value of mineral reserves established through the purchase price allocation of a business combination, performing audit procedures to evaluate the reasonableness of management’s judgments and estimates related to the iron ore mineral reserve inputs required a high degree of auditor judgment and an increased extent of effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s significant judgments and assumptions related to iron ore mineral reserve quantities and the related iron ore mine closure dates included the following, among others:

•We tested the operating effectiveness of internal controls related to the Company’s estimation of iron ore mineral reserve quantities and the related iron ore mine closure dates.

•We evaluated the experience, qualifications and objectivity of management’s experts, including in-house iron ore mine engineers.

•For an iron ore mine subject to the Company’s routine annual assessment we evaluated management’s assessment by:

◦Understanding the process used by management to survey and analyze the geological and operational status of current year iron ore mine production.

◦Evaluating the historical accuracy of management’s technical model as compared to actual iron ore mine production results.

◦Comparing the iron ore mine plan, updated for current year depletion, to

▪Presentations to the Audit Committee.

▪Information by asset group, asset retirement obligation valuation models, depreciation, depletion and amortization expense calculations and mineral reserve purchase price allocation valuation models.

•For an iron ore mine subject to the Company’s periodic in-depth evaluation of its iron ore mineral reserve estimate:

◦We evaluated management’s determination of the size and scope of the iron ore body, by:

▪Understanding the process used by management to complete research and exploration activities including mineralized resource drill samples.

▪Understanding the methodology utilized by management to apply the research and exploration data to the development of a technical model of the iron ore body.

▪Evaluating the historical accuracy of management’s technical model as compared to actual iron ore mine production results.

139

◦We evaluated management’s estimates of future iron ore prices, production costs and capital expenditures (the “financial assumptions”), by:

▪Understanding and testing the methodology utilized by management for development of the future iron ore prices recognizing that the price shall not exceed the three-year trailing average index price of iron ore adjusted to the Company’s realized price.

▪Evaluated management’s ability to accurately forecast future iron ore prices, production costs and capital expenditures by comparing actual results to management’s historical forecasts.

▪Evaluated the reasonableness of management’s estimates of future iron ore prices to forecasted information included in analyst reports.

▪Evaluated the reasonableness of management’s forecast for production costs and capital expenditures by comparing the forecasts to: (1) historical results and (2) internal communications to management and the Board of Directors.

◦We evaluated management’s iron ore mine plan for the proven and probable mineral reserves, by:

▪Understanding the process used by management to develop the iron ore mine plan for proven and probable iron ore mineral reserves applying key inputs such as the technical model of the iron ore body and the financial assumptions.

▪Comparing the iron ore mine plan to

Acquisitions — AK Steel —Refer to Note 3 to the financial statements

Critical Audit Matter Description

The Company completed the acquisition of AK Steel Holding Corporation for approximately $1.5 billion on March 13, 2020. The Company accounted for the acquisition under the acquisition method of accounting for business combinations. Accordingly, the purchase price was initially allocated to three operations of the AK Steel business including Steelmaking, Tooling and Stamping and Tubular using a discounted cash flow model (the “Operations Allocation”). Following the Operations Allocation, the purchase price was then allocated to the assets acquired and liabilities assumed comprising the three operations of the AK Steel business based on their respective fair values, including $174 million goodwill balance assigned to the Tooling and Stamping and Tubular operations. The Operations Allocation required management to make significant estimates and assumptions related to forecasts of future revenues and earnings before interest, taxes, depreciation, and amortization (EBITDA) and discount rates.

Given the Operations Allocation requires management to make significant estimates and assumptions related to the forecasts of future revenues and EBITDA (the “Forecasts”), as well as the selection of the discount rates, and considering to the sensitivity of the allocated goodwill balance to changes in projected future cash flows at the Steelmaking, Tooling and Stamping, and Tubular operations, performing audit procedures to evaluate the reasonableness of the Forecasts and selected discount rates required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Forecasts and the selection of the discount rates included the following, among others:

•We tested the operating effectiveness of internal controls over management’s purchase price allocation, such as controls related to management’s Forecasts and the selection of the discount rates.

140

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our President and Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based solely on the definition of “disclosure controls and procedures” in Rule 13a-15(e) promulgated under the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of the end of the period covered by this report, we carried out an evaluation under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, our President and Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective.

Management's 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 under Rule 13a-15(f) promulgated under the Exchange Act.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's consolidated financial statements for external purposes in accordance with generally accepted accounting principles.

Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit the preparation of the consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with appropriate authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the consolidated financial statements.

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

Management conducted an assessment of the Company's internal control over financial reporting as of December 31, 2020 using the framework specified in Internal Control - Integrated Framework (2013), published by the Committee of Sponsoring Organizations of the Treadway Commission. We have excluded from our assessment the internal control over financial reporting at AK Steel, which was acquired on March 13, 2020, and whose assets as of December 31, 2020 constituted 32% of the Company’s consolidated total assets as of December 31, 2020, and whose revenues for the period from March 13, 2020 through December 31, 2020, inclusive, constituted 67% of the Company’s consolidated revenues for the year ended December 31, 2020. Management also excluded from our assessment the internal control over financial reporting at ArcelorMittal USA, which was acquired on December 9, 2020, and whose assets as of December 31, 2020 constituted 49% of the Company’s consolidated total assets as of December 31, 2020, and whose revenues for the period from December 9, 2020 through December 31, 2020, inclusive, constituted 8% of the Company’s consolidated revenues for the year ended December 31, 2020.

Based on such assessment, management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2020.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2020 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report that appears herein.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting or in other factors that occurred during our last 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 shareholders and the Board of Directors of

Cleveland-Cliffs Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Cleveland-Cliffs Inc. and subsidiaries (the "Company") as of December 31, 2020, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020, of the Company and our report dated February 26, 2021, expressed an unqualified opinion on those financial statements.

As described in Management’s Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at AK Steel, which was acquired on March 13, 2020, and whose assets as of December 31, 2020 constituted 32% of the Company’s consolidated total assets as of December 31, 2020, and whose revenues for the period from March 13, 2020 through December 31, 2020, inclusive, constituted 67% of the Company’s consolidated revenues for the year ended December 31, 2020. Management also excluded from its assessment the internal control over financial reporting at ArcelorMittal USA, which was acquired on December 9, 2020, and whose assets as of December 31, 2020 constituted 49% of the Company’s consolidated total assets as of December 31, 2020, and whose revenues for the period from December 9, 2020 through December 31, 2020, inclusive, constituted 8% of the Company’s consolidated revenues for the year ended December 31, 2020. Accordingly, our audit did not include the internal control over financial reporting at either AK Steel or ArcelorMittal USA.

Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

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

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

EXHIBIT 4.48

DESCRIPTION OF SECURITIES REGISTERED UNDER

SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

The following is a summary of the terms and provisions of the common shares, par value $0.125 per share (“Common Shares”), of Cleveland-Cliffs Inc., an Ohio corporation (the “Company”), and is qualified by reference to the Company’s articles of incorporation and regulations, which are incorporated by reference herein and attached as exhibits to the Company’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, and to applicable provisions of Ohio law.

Common Shares

The Company has authorized 600,000,000 Common Shares. The holders of Common Shares are entitled to one vote for each share on all matters upon which shareholders have the right to vote and, upon proper notice, are entitled to cumulative voting rights in the election of directors. The Common Shares do not have any preemptive rights, are not subject to redemption and do not have the benefit of any sinking fund. Holders of Common Shares are entitled to receive such dividends as the Company’s directors from time to time may declare out of funds legally available therefor. Entitlement to dividends is subject to the preferences granted to other classes of securities the Company has or may have outstanding in the future. In the event of the Company’s liquidation, holders of Common Shares are entitled to share in any of the Company’s assets remaining after satisfaction in full of its liabilities and satisfaction of such dividend and liquidation preferences as may be possessed by the holders of other classes of securities the Company has or may have outstanding in the future.

Preferred Stock

The Company has authorized 3,000,000 shares of serial preferred stock, Class A, without par value (“Class A Preferred Stock”), and 4,000,000 shares of serial preferred stock, Class B, without par value (“Class B Preferred Stock” and, collectively with the Class A Preferred Stock, “Preferred Stock”), of which 583,273 shares have been designated as the “Series B Participating Redeemable Preferred Stock.” Under the Company’s articles of incorporation, the Company’s board of directors can issue, without further shareholder action, up to 3,000,000 shares of Class A Preferred Stock and up to 4,000,000 shares of Class B Preferred Stock, in each case, with such rights and restrictions as the Company’s board of directors may determine, subject to any shares of Preferred Stock of the applicable class then outstanding.

In some cases, the issuance of Preferred Stock could delay, defer or prevent a change in control and make it harder to remove present management, without further action by the Company’s shareholders. Under some circumstances, Preferred Stock could also decrease the amount of earnings and assets available for distribution to holders of Common Shares if the Company liquidates or dissolves and could also restrict or limit dividend payments to holders of Common Shares.

Series B Participating Redeemable Preferred Stock

The Series B Participating Redeemable Preferred Stock ranks senior to the Common Shares with respect to dividend rights and rights on the distribution of assets upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of, and certain bankruptcy events involving, the Company. Each share of Series B Participating Redeemable Preferred Stock entitles its holder to receive a multiple, initially equal to 100 (subject to certain anti-dilution adjustments, the “Applicable Multiple”), of the aggregate amount per share of all dividends declared on the Common Shares. In addition, from and after the 24-month anniversary of the issue date of the Series B Participating Redeemable Preferred Stock (the “24-Month Anniversary”), each holder of a share of Series B Participating Redeemable

Preferred Stock is entitled to receive cash dividends (the “Additional Dividends”) accruing and compounding on a daily basis at the initial rate of 10% per annum on the sum of (i) the Applicable Multiple then in effect times the volume-weighted average price of the Common Shares for the 20 consecutive trading days ending on the trading day immediately preceding the 24-Month Anniversary and (ii) the amount of accumulated and unpaid dividends on the Series B Participating Redeemable Preferred Stock to, but not including, the 24-Month Anniversary, if any, which rate will increase by 2% per annum at the end of each six-month period following the 24-Month Anniversary. Additional Dividends will be payable, when, as and if declared by the Company’s board of directors, in quarterly installments.

The Series B Participating Redeemable Preferred Stock is redeemable, in whole or in part, at the Company’s option at any time and from time to time on and after the date that is 180 days after the issue date at a redemption price per share equal to the Applicable Multiple then in effect times the volume-weighted average price of the Common Shares for the 20 consecutive trading days ending on the trading day immediately preceding the date fixed for redemption, plus accumulated and unpaid dividends to, but not including, the redemption date.

In the event of a change of control of the Company, the Series B Participating Redeemable Preferred Stock will be subject to mandatory redemption at a redemption price per share equal to the Applicable Multiple then in effect times the volume-weighted average price of the Common Shares for the 20 consecutive trading days ending on the trading day immediately preceding the closing date of the transaction constituting such change of control.

In addition, pursuant to the terms of the Series B Participating Redeemable Preferred Stock, the Company is restricted from effecting any merger or consolidation with or into another entity unless the Series B Participating Redeemable Preferred Stock remains outstanding following the merger or consolidation, is exchanged for new preferred stock with substantially identical terms or is to be redeemed in connection with the closing of such merger or consolidation.

In addition to the foregoing, the Series B Participating Redeemable Preferred Stock is subject to the express terms of the Class B Preferred Stock as set forth in the Company’s articles of incorporation, except that holders of Series B Participating Redeemable Preferred Stock, in their capacity as such, do not have the right to vote with the other series of Class B Preferred Stock then outstanding, if any, voting separately as a class, for the election of additional directors of the Company upon certain defaults by the Company in the payment of dividends, as provided in the Company’s articles of incorporation.

Ohio Control Share Acquisition Statute

The Ohio Control Share Acquisition Statute requires the prior authorization of the shareholders of certain corporations in order for any person to acquire, either directly or indirectly, shares of that corporation that would entitle the acquiring person to exercise or direct the exercise of 20% or more of the voting power of that corporation in the election of directors or to exceed specified other percentages of voting power. In the event an acquiring person proposes to make such an acquisition, the person is required to deliver to the corporation a statement disclosing, among other things, the number of shares owned, directly or indirectly, by the person, the range of voting power that may result from the proposed acquisition and the identity of the acquiring person. Within 10 days after receipt of this statement, the corporation must call a special meeting of shareholders to vote on the proposed acquisition. The acquiring person may complete the proposed acquisition only if the acquisition is approved by the affirmative vote of the holders of at least a majority of the voting power of all shares entitled to vote in the election of directors represented at the meeting excluding the voting power of all “interested shares.” Interested shares include any shares held by the acquiring person and those held by officers and directors who are employees of the corporation as well as by certain others, including many holders commonly characterized as arbitrageurs. The Ohio Control Share Acquisition Statute does not apply to a corporation if its articles of incorporation or code of regulations state that the statute does not apply to a

corporation. Neither the Company’s articles of incorporation nor its regulations contain a provision opting out of this statute.

Ohio Interested Shareholder Statute

Chapter 1704 of the Ohio Revised Code prohibits certain corporations from engaging in a “chapter 1704 transaction” with an “interested shareholder” for a period of three years after the date of the transaction in which the person became an interested shareholder, unless, among other things:

•the articles of incorporation expressly provide that the corporation is not subject to the statute (the Company has not made this election); or

•the board of directors of the corporation approves the chapter 1704 transaction or the acquisition of the shares before the date the shares were acquired.

After the three-year moratorium period, the corporation may not consummate a chapter 1704 transaction unless, among other things, it is approved by the affirmative vote of the holders of at least two-thirds of the voting power in the election of directors and the holders of a majority of the voting shares, excluding all shares beneficially owned by an interested shareholder or an affiliate or associate of an interested shareholder, or the shareholders receive certain minimum consideration for their shares. A chapter 1704 transaction includes certain mergers, sales of assets, consolidations, combinations and majority share acquisitions involving an interested shareholder. An interested shareholder is defined to include, with limited exceptions, any person who, together with affiliates and associates, is the beneficial owner of a sufficient number of shares of the corporation to entitle the person, directly or indirectly, alone or with others, to exercise or direct the exercise of 10% or more of the voting power in the election of directors after taking into account all of the person’s beneficially owned shares that are not then outstanding.

(b)the representations and warranties of each Loan Party set forth in Article 4 of the Amended Credit Agreement and the other Loan Documents are true and correct in all material respects (unless such representation and warranty is qualified by “materiality” or “Material Adverse Effect” or other similar qualification, in which case such representation and warranty shall be true and correct in all respects) on and as of the Effective Date (both immediately before and immediately after giving effect to this Amendment), except to the extent that such representations and warranties specifically refer to an earlier date or specified period, in which case they shall be true and correct in all material respects (unless such representation and warranty is qualified by “materiality” or “Material Adverse Effect” or other similar qualification, in which case such representation and warranty shall be true and correct in all respects) as of such earlier date or for such specified period.

ASSET-BASED REVOLVING CREDIT AGREEMENT

THIS ASSET-BASED REVOLVING CREDIT AGREEMENT, is dated as of March 13, 2020, by and among the lenders identified on the signature pages hereof (each of such lenders, together with its successors and permitted assigns, is referred to hereinafter as a “Lender”, as that term is hereinafter further defined), BANK OF AMERICA, N.A., as administrative agent for each member of the Lender Group and the Bank Product Providers (in such capacity, together with its successors and assigns in such capacity, “Agent”), and CLEVELAND-CLIFFS INC., an Ohio corporation (“Parent”).

The parties agree as follows:

1.DEFINITIONS AND CONSTRUCTION.

1.1    Definitions. Capitalized terms used in this Agreement shall have the meanings specified therefor on Schedule 1.1.

1.2    Accounting Terms. All accounting terms not specifically defined herein shall be construed in accordance with GAAP; provided, that if Parent notifies Agent that Borrowers request an amendment to any provision hereof to eliminate the effect of any Accounting Change occurring after the Closing Date or in the application thereof on the operation of such provision (or if Agent notifies Borrowers that the Required Lenders request an amendment to any provision hereof for such purpose), regardless of whether any such notice is given before or after such Accounting Change or in the application thereof, then Agent and Borrowers agree that they will negotiate in good faith amendments to the provisions of this Agreement that are directly affected by such Accounting Change with the intent of having the respective positions of the Lenders and Borrowers after such Accounting Change conform as nearly as possible to their respective positions as of the date of this Agreement and, until any such amendments have been agreed upon and agreed to by the Required Lenders, the provisions in this Agreement shall be calculated as if no such Accounting Change had occurred; provided further that the parties hereto agree that the adoption of ASC 606 by the Borrowers and their Subsidiaries prior to the date hereof shall not constitute an Accounting Change. When used herein, the term “financial statements” shall include the notes and schedules thereto. Whenever the term “Parent” is used in respect of a financial covenant or a related definition, it shall be understood to mean Parent and its Subsidiaries on a consolidated basis, unless the context clearly requires otherwise. For purposes of calculating the Tranche A Borrowing Base, the Tranche B Borrowing Base and the Aggregate Borrowing Base, such calculation of Inventory shall be on a “first-in, first-out” basis. Notwithstanding anything to the contrary contained herein, (a) all financial statements delivered hereunder shall be prepared, and all financial covenants contained herein shall be calculated, without giving effect to any election under the Statement of Financial Accounting Standards No. 159 (or any similar accounting principle) permitting a Person to value its financial liabilities or Indebtedness at the fair value thereof, (b) the term “unqualified opinion” as used herein to refer to opinions or reports provided by accountants shall mean an opinion or report that does not include any explanation, supplemental comment, or other comment concerning the ability of the applicable Person to continue as a going concern or concerning the scope of the audit (other than a “going concern” or like qualification or exception resulting solely from (i) maturity of any Indebtedness (including the Revolver Commitments) occurring within one (1) year from the time such opinion is delivered, and/or (ii) the projected or potential breach of any of the financial covenants set forth in this Agreement or any agreement governing any Indebtedness during the one-year period following the date such opinion is delivered), and (c) notwithstanding the foregoing or anything else to the contrary in this Agreement, all leases of the Borrowers and their respective Subsidiaries that were treated as “operating leases” prior to the adoption of ASC 842 shall continue to be accounted for as such for all purposes under the Loan Documents. For purposes of determining satisfaction of the Payment Conditions set forth in this Agreement or the financial covenant set forth in Section 7 of this Agreement, such determination shall be calculated on a pro forma basis (including pro forma adjustments arising out of events which are directly attributable to any Permitted Acquisition, Permitted Disposition or Permitted Investment that are factually supportable, and are expected to have a continuing impact, in each case determined on a basis

consistent with Article 11 of Regulation S-X promulgated under the Securities Act and as interpreted by the staff of the SEC or in such other manner acceptable to Agent).

1.3     Limited Condition Transaction. Notwithstanding anything to the contrary herein, for purposes of determining compliance with any test or covenant contained in this Agreement with respect to any period during which any Limited Condition Transaction is consummated, the Fixed Charge Coverage Ratio shall be calculated with respect to such period and such Limited Condition Transaction on a pro forma basis; provided that, for purposes of determining the permissibility of any Limited Condition Transaction under this Agreement, at the option of Parent (Parent’s election to exercise such option in connection with any Limited Condition Transaction, an “LCA Election”) the date of determination for calculation of any such ratios shall be deemed to be the date the definitive agreements for such Limited Condition Transaction are entered into (the “LCA Test Date”) and if, after giving pro forma effect to the Limited Condition Transaction and all related transactions (including incurrences or prepayments of Indebtedness and Liens, dispositions and Restricted Payments) to be entered into in connection therewith as if they had occurred at the beginning of the most recent date of determination ending prior to the LCA Test Date, Parent could have entered into such Limited Condition Transaction on the relevant LCA Test Date in compliance with such ratio, such ratio shall be deemed to have been complied with. For the avoidance of doubt, if the Parent has made an LCA Election and any of the ratios for which compliance was determined or tested as of the LCA Test Date is not met as a result of fluctuations in any such ratio, including due to fluctuations in EBITDA of the Parent and its Subsidiaries, at or prior to the consummation of the relevant Limited Condition Transaction, such ratio will be deemed to have been met notwithstanding such fluctuations solely for purposes of determining whether the relevant Limited Condition Transaction is permitted to be consummated. If the Parent has made an LCA Election for any Limited Condition Transaction, then in connection with any subsequent calculation of any ratio availability with respect to any other transaction (including any incurrence or prepayment of Indebtedness or Liens, dispositions or Restricted Payments) on or following the relevant LCA Test Date and prior to the earlier of the date on which such Limited Condition Transaction is consummated, such Limited Condition Transaction is terminated or expires without consummation of such Limited Condition Transaction, any such ratio shall be calculated on a pro forma basis assuming such Limited Condition Transaction and other transactions in connection therewith have been consummated. For determining permissibility of a Limited Condition Transaction, for purposes of determining compliance with any provision of this Agreement which requires that no Default or Event of Default, as applicable, has occurred, is continuing or would result from the consummation of such Limited Condition Transaction, as applicable, such condition shall, at the option of the Parent, be deemed satisfied, so long as no Default or Event of Default, as applicable, exists on the date the definitive agreements for such Limited Condition Transaction are entered into and no Event of Default under Section 8.1, 8.4 or 8.5 exists on the date of consummation of the Limited Condition Transaction or would result therefrom. For the avoidance of doubt, if the Parent has exercised its option under this Section 1.3, and any Default or Event of Default occurs following the date the definitive agreements for the applicable Limited Condition Transaction were entered into and prior to the consummation of such Limited Condition Transaction, any such Default or Event of Default (other than an Event of Default under Section 8.1, 8.4 or 8.5) shall be deemed to not have occurred or be continuing for purposes of determining whether such Limited Condition Transaction is permitted hereunder.

1.4     Construction.

(a)    Unless the context of this Agreement or any other Loan Document clearly requires otherwise, references to the plural include the singular, references to the singular include the plural, the terms “includes” and “including” are not limiting, and the term “or” has, except where otherwise indicated, the inclusive meaning represented by the phrase “and/or.” The words “hereof,” “herein,” “hereby,” “hereunder,” and similar terms in this Agreement or any other Loan Document refer to this Agreement or such other Loan Document, as the case may be, as a whole and not to any particular provision of this Agreement or such other Loan Document, as the case may be. Section, subsection, clause, schedule, and exhibit references herein are to this Agreement unless otherwise specified. Any reference in this Agreement or in any other Loan Document to any agreement, instrument, or document

2

shall include all alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements, thereto and thereof, as applicable (subject to any restrictions on such alterations, amendments, changes, extensions, modifications, renewals, replacements, substitutions, joinders, and supplements set forth herein). The words “asset” and “property” shall be construed to have the same meaning and effect and to refer to any and all tangible and intangible assets and properties. Any reference herein to any Person shall be construed to include such Person’s successors and assigns. Any requirement of a writing contained herein or in any other Loan Document shall be satisfied by the transmission of a Record.

(b)    Any reference herein or in any other Loan Document to the satisfaction, repayment, or payment in full of the Obligations shall mean (i) the payment or repayment in full in immediately available funds of (A) the principal amount of, and interest accrued and unpaid with respect to, all outstanding Loans, together with the payment of any premium applicable to the repayment of the Loans, (B) all Lender Group Expenses that have accrued and are unpaid for which an invoice has been provided to Parent, and (C) all fees or charges that have accrued hereunder or under any other Loan Document (including the Letter of Credit Fees and the Unused Line Fee) and are unpaid, (ii) in the case of contingent reimbursement obligations with respect to Letters of Credit, providing Letter of Credit Collateralization, (iii) in the case of obligations with respect to Bank Products (other than Hedge Obligations), providing Bank Product Collateralization, (iv) the receipt by Agent of cash collateral in order to secure any other contingent Obligations for which a claim or demand for payment has been made on or prior to such time or in respect of matters or circumstances known to Agent or a Lender at such time that are reasonably expected to result in any loss, cost, damage, or expense (including attorneys' fees and legal expenses), such cash collateral to be in such amount as Agent reasonably determines is appropriate to secure such contingent Obligations, (v) the payment or repayment in full in immediately available funds of all other outstanding Obligations (including the payment of any termination amount then applicable (or which would or could become applicable as a result of the repayment of the other Obligations) under Hedge Agreements provided by Hedge Providers) other than (A) unasserted contingent indemnification Obligations, (B) any Bank Product Obligations (other than Hedge Obligations) that, at such time, are allowed by the applicable Bank Product Provider to remain outstanding without being required to be repaid or cash collateralized, and (C) any Hedge Obligations that, at such time, are allowed by the applicable Hedge Provider to remain outstanding without being required to be repaid, and (vi) the termination of all of the Revolver Commitments of the Lenders.

(c)    Any reference herein or in any other Loan Document to any law, statute, rule or regulation shall include all statutory and regulatory provisions consolidating, amending, replacing, supplementing or interpreting such law.

(d)    Any reference herein to a merger, transfer, consolidation, amalgamation, consolidation, assignment, sale, disposition or transfer, or similar term, shall be deemed to apply to a division of or by a limited liability company or a limited partnership, or an allocation of assets to a series of a limited liability company or a limited partnership (or the unwinding of such a division or allocation), as if it were a merger, transfer, consolidation, amalgamation, consolidation, assignment, sale or transfer, or similar term, as applicable, to, of or with a separate Person. Any division of a limited liability company or a limited partnership shall constitute a separate Person hereunder (and each division of any limited liability company or any limited partnership that is a Subsidiary, Joint Venture or any other like term shall also constitute such a Person or entity).

1.5    Time References. Unless the context of this Agreement or any other Loan Document clearly requires otherwise, all references to time of day refer to Chicago time. For purposes of the computation of a period of time from a specified date to a later specified date, the word “from” means “from and including” and the words “to” and “until” each means “to and including”; provided that, with respect to a computation of fees or interest payable to Agent or any Lender, such period shall include the first day, but not the last day so long as payment thereof is received prior to the time specified in Section 2.6 hereof, but in any event shall consist of at least one (1) full day.

3

1.6    Schedules and Exhibits. All of the schedules and exhibits attached to this Agreement shall be deemed incorporated herein by reference.

1.7     Dollar Equivalent.

(a)    Agent shall determine the Dollar Equivalent of any Letter of Credit not denominated in Dollars (i) on the date of issuance thereof and the date of any amendment thereto that increases the face amount thereof, in each case using the Spot Rate for the Agreed Currency other than Dollars in relation to Dollars in effect on the date immediately prior to the applicable issuance or amendment date, and (ii) at such other times as may be determined by either Agent or an Issuing Bank in its Permitted Discretion, in each case using the Spot Rate for the Agreed Currency other than Dollars in relation to Dollars in effect on the date of determination. Each amount determined pursuant to this Section 1.7(a) shall be the Dollar Equivalent of the applicable Letter of Credit until the next calculation thereof pursuant to the preceding sentences of this Section 1.7(a), absent manifest error. Upon the request of the Borrowers, Agent shall notify Borrowers and the Lenders of each calculation of the Dollar Equivalent of each Letter of Credit denominated in an Agreed Currency other than Dollars.

(b)    Wherever in this Agreement in connection with any Letter of Credit, an amount, such as a required minimum, sublimit, maximum, or multiple amount, is expressed in Dollars, but such Letter of Credit is denominated in an Agreed Currency other than Dollars, such amount shall be the Agreed Currency Equivalent of such Dollar amount (rounded to the nearest unit of such Agreed Currency that is equivalent to one (1) Dollar, with 0.5 of a unit being rounded upward).

(c)    Principal, interest, reimbursement obligations, cash collateral for reimbursement obligations, fees, and all other amounts payable to Agent or Lenders under this Agreement and the other Loan Documents shall be payable (except as otherwise specifically provided herein) in Dollars.

(d)    If at any time following one or more fluctuations in the exchange rate of any Agreed Currency other than Dollars against the Dollar, all or any part of the Obligations exceeds more than 102% of any other limit set forth herein for such Obligations, the Borrowers of such Obligations shall within one (1) Business Day of written notice of same from Agent immediately make the necessary payments or repayments to reduce such Obligations, or Cash Collateralize such Obligations, to an amount necessary to eliminate such excess over 100% of such limit.

1.8    LIBOR Rate. Agent does not warrant, nor accept responsibility, nor shall Agent have any liability with respect to the administration, submission, or any other matter related to the rates in the definition of LIBOR Rate or with respect to any comparable or successor rate thereto (including as may be provided pursuant to Section 2.13(d)(iv)).

1.9    Pro Forma Effect of AMUSA Acquisition. Notwithstanding anything contained herein, for purposes of calculating EBITDA and Fixed Charges Coverage Ratio, the EBITDA and all of the components of Fixed Charge Coverage Ratio of the AMUSA Target Loan Parties and their Subsidiaries shall be deemed to be zero ($0) for any period ending prior to the Second Amendment Effective Date.

2.     REVOLVING LOANS AND TERMS OF PAYMENT.

2.1    Revolving Loans

(a)    Subject to the terms and conditions of this Agreement, and during the term of this Agreement, each Tranche A Revolving Lender agrees (severally, not jointly or jointly and severally) to make revolving loans (“Tranche A Revolving Loans”) in Dollars to the Borrowers in a principal amount not to exceed the lesser of:

(i)    such Lender’s Tranche A Revolver Commitment at such time, or

4

(ii)    such Lender’s Pro Rata Share of an amount equal to (x) the Tranche A Line Cap at such time less (y) the sum of (A) the Letter of Credit Usage at such time, (B) the principal amount of Swing Loans outstanding at such time and (C) the principal amount of Tranche A Revolving Loans outstanding at such time; provided that, if any Tranche B Facility exists at such time, no Tranche A Revolving Loans may be made to any Borrower unless the amount of outstanding Tranche B Revolving Loans is equal to the Tranche B Line Cap;

(b)    Subject to the terms and conditions of this Agreement, from the First Amendment Effective Date and until the earlier of one Business Day prior to the Maturity Date and the termination of the Tranche B Revolver Commitment of such Lender, each Tranche B Revolving Lender agrees (severally, not jointly or jointly and severally) to make Tranche B Revolving Loans in Dollars to the Borrowers in a principal amount not to exceed such Lender’s Tranche B Revolver Commitment at such time; provided that after giving effect to such transaction, the aggregate amount of the Tranche B Revolving Loans then outstanding would not exceed the Tranche B Line Cap.

Anything to the contrary in clauses (a) and (b) of this Section 2.1(a) notwithstanding, Agent shall have the right (but not the obligation), in the exercise of its Permitted Discretion, to establish and increase or decrease Receivable Reserves, Inventory/Equipment Reserves, Bank Product Reserves, Pari Secured Hedge Reserves, Dilution Reserves and other Reserves against the Tranche A Borrowing Base or the Tranche A Line Cap, including based on review of the Borrowers’ employment and labor contracts; provided that no reserve shall be established, increased or decreased except upon not less than three (3) Business Days’ prior written notice from the Agent to the Parent, during which period employees, agents or other representatives of the Agent shall use commercially reasonable efforts to be available during regular business hours to discuss any such proposed establishment or modification of such reserve with the Parent and, without limiting the right of the Agent to establish or modify reserves in its Permitted Discretion, the Parent may take such action as may be required so that the circumstances, conditions, events or contingencies that are the basis for such reserve or modification thereof no longer exist, in a manner and to the extent reasonably satisfactory to the Agent in its Permitted Discretion; provided that no such prior written notice shall be required for any modifications to any reserves (x) during any Cash Dominion Trigger Period, during a Financial Covenant Period, during any period of weekly collateral reporting as provided in Section 5.2, or after the occurrence and during the continuance of any Event of Default or (y) resulting by virtue of mathematical calculations of the amount of the reserves in accordance with the methodology of calculation previously utilized. The amount of any Receivable Reserve, Inventory/Equipment Reserve, Bank Product Reserve, Pari Secured Hedge Reserves or other Reserve established by Agent shall have a reasonable relationship to the event, condition, other circumstance, or fact that is the basis for such reserve as determined by Agent in its Permitted Discretion and shall not be duplicative of any other reserve established and currently maintained. Upon establishment or increase in reserves, Agent agrees to make itself available to discuss the reserve or increase, and Borrowers may take such action as may be required so that the event, condition, circumstance, or fact that is the basis for such reserve or increase no longer exists, in a manner and to the extent reasonably satisfactory to Agent in the exercise of its Permitted Discretion. In no event shall such notice and opportunity limit the right of Agent to establish or change such Receivable Reserve, Inventory/Equipment Reserve, Bank Product Reserve, Pari Secured Hedge Reserves or other Reserves, unless Agent shall have determined, in its Permitted Discretion, that the event, condition, other circumstance, or fact that was the basis for such Receivable Reserve, Inventory/Equipment Reserve, Bank Product Reserve, Pari Secured Hedge Reserves or other Reserves or such change no longer exists or has otherwise been adequately addressed by Borrowers.

(c)    The outstanding principal amount of the Revolving Loans, together with interest accrued and unpaid thereon, shall constitute Obligations and shall be due and payable on the Maturity Date or, if earlier, on the date on which they are declared due and payable pursuant to the terms of this Agreement.

(d)    Amounts borrowed pursuant to this Section 2.1 may be repaid and, subject to the terms and conditions of this Agreement, reborrowed at any time during the term of this Agreement.

5

2.2    Additional Borrowers.

(a)    The Parent may from time to time designate one or more wholly-owned Subsidiaries of Parent organized in the United States as an Additional Borrower by delivering to the Agent:

(i)    all documentation and other customary information required by regulatory authorities under applicable “know your customer” and anti-money laundering rules and regulations, including, without limitation, the Patriot Act, that the Agent or any Lender has reasonably requested, including, if such Subsidiary qualifies as a “legal entity customer” under the Beneficial Ownership Regulation, a Beneficial Ownership Certification in relation to such Subsidiary, without any written objection submitted by any Lender or the Agent within five (5) Business Days of its receipt of such documentation and other information;

(ii)    solely to the extent such Subsidiary is not already a Loan Party, (A) all documents, joinders, supplements, updated schedules, instruments, certificates and agreements and all other actions and information, then required by or in respect of such Subsidiary by Section 5.11 or by the Guaranty and Security Agreement (without giving effect to any grace periods for delivery of such items, the updating of such information or the taking of such actions), (B) a customary opinion of counsel of such Subsidiary and (C) a customary secretary’s certificate attaching such documents as were delivered by the existing Borrowers on the Closing Date;

(iii)    promissory notes in respect of such Subsidiary in its capacity as Additional Borrower in favor of any Lender requesting such promissory notes, in form and substance consistent with the notes (if any) provided by the existing Borrowers as of the Closing Date; and

(iv)    a joinder agreement in form and substance reasonably satisfactory to the Agent whereby such Subsidiary becomes party hereto as a Borrower.

(b)    The designation of any wholly-owned Subsidiary of Parent organized in the United States as an Additional Borrower shall only be effective two (2) Business Days following the delivery of the documents set forth in, and satisfaction of the requirements of, Section 2.2(a).

2.3     Borrowing Procedures and Settlements.

(a)    Procedure for Borrowings. Each Borrowing shall be made by a written request by an Authorized Person delivered to Agent and received by Agent no later than (i) 12:00 noon on the Business Day that is the requested Funding Date in the case of a request for a Swing Loan or a Revolving Loan that is a Base Rate Loan and (ii) 12:00 noon on the Business Day that is three (3) Business Days (or solely with respect to a Borrowing on the Closing Date, one (1) Business Day) prior to the requested Funding Date in the case of a Revolving Loan that is a LIBOR Rate Loan, in each case, specifying (A) the amount of such Borrowing, (B) the requested Funding Date (which shall be a Business Day), (C) whether such Borrowing is to be a Borrowing of Base Rate Loans or a Borrowing of LIBOR Rate Loans, (D) in the case of a Borrowing of LIBOR Rate Loans, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period” and (E) whether the Borrowing is of Tranche A Revolving Loans or Tranche B Revolving Loans; provided that if any Tranche B Facility exists at such time, such Borrowing shall be Tranche A Revolving Loans unless the outstanding principal amount of Tranche B Revolving Loans is less than the Tranche B Line Cap, in which case up to an amount equal to the Tranche B Line Cap minus the outstanding principal amount of Tranche B Revolving Loans of such Revolving Loans shall be Tranche B Revolving Loans, and the remaining amount of such Revolving Loans shall be Tranche A Revolving Loans; provided that Agent may, in its sole discretion, elect to accept as timely requests that are received later than the times specified above on the applicable Business Day. In lieu of delivering the above-described written request, any Authorized Person may give Agent electronic notice of such request by the required time. In such circumstances, Borrowers agree that any such electronic notice will be confirmed in writing within 24

6

hours of the giving of such electronic notice, but the failure to provide such written confirmation shall not affect the validity of the request.

(b)    [Reserved].

(c)    Making of Swing Loans. Subject to the terms and conditions of this Agreement, so long as either (i) the aggregate amount of Swing Loans made since the last Settlement Date, minus all payments or other amounts applied to Swing Loans since the last Settlement Date, plus the amount of the requested Swing Loan does not exceed $125,000,000, or (ii) the Swing Lender, in its sole discretion, agrees to make a Swing Loan notwithstanding the foregoing limitation, the Swing Lender shall make a Revolving Loan (any such Revolving Loan made by the Swing Lender pursuant to this Section 2.3(c) being referred to as a “Swing Loan” and all such Revolving Loans being referred to as “Swing Loans”) in Dollars available to the Borrowers on the Funding Date applicable thereto by transferring immediately available funds in the amount of such requested Borrowing to the Designated Account. Each Swing Loan shall be deemed to be a Revolving Loan hereunder and shall be subject to all the terms and conditions (including Section 3) applicable to other Revolving Loans, except that all payments (including interest) on any Swing Loan shall be payable to the Swing Lender solely for its own account. Subject to the provisions of Section 2.3(f)(iii), the Swing Lender shall not make and shall not be obligated to make any Swing Loan if the Swing Lender has actual knowledge that (A) one or more of the applicable conditions precedent set forth in Section 3 will not be satisfied on the requested Funding Date for the applicable Borrowing, or (B) the requested Borrowing would exceed the Excess Availability on such Funding Date. The Swing Lender shall not otherwise be required to determine whether the applicable conditions precedent set forth in Section 3 have been satisfied on the Funding Date applicable thereto prior to making any Swing Loan. The Swing Loans shall be secured by Liens granted under the Loan Documents, constitute Revolving Loans and Obligations, and bear interest at the rate applicable from time to time to Revolving Loans that are Base Rate Loans.

(d)    [Reserved].

(e)    Making of Revolving Loans.

(i)    In the event that a Swing Lender refuses to or is not obligated to make a Swing Loan, then after receipt of a request for a Borrowing pursuant to Section 2.3(a), Agent shall notify the Lenders by telecopy, telephone, email, or other electronic form of transmission, of the requested Borrowing; such notification to be sent on the Business Day that is one (1) Business Day prior to the requested Funding Date (or, in the case of a request for a Loan delivered on the requested Funding Date, no later than 1:00 p.m. on the requested Funding Date). If Agent has notified the Lenders of a requested Borrowing on the Business Day that is one (1) Business Day prior to the Funding Date (or, in the case of a request for a Loan delivered on the requested Funding Date), then each Lender shall make the amount of such Lender’s Pro Rata Share of the requested Borrowing available to Agent in immediately available funds, to the Agent’s Account, not later than 3:00 p.m., in the case of any Loan requested to be funded on the Funding Date, or 10:00 a.m., in the case of any other request, in each case, on the Business Day that is the requested Funding Date. After Agent’s receipt of the proceeds of such Revolving Loans from the Lenders, Agent shall make the proceeds thereof available to applicable Borrowers on the applicable Funding Date by transferring immediately available funds equal to such proceeds received by Agent to the Designated Account; provided, that, subject to the provisions of Sections 2.3(f)(iii) and 2.3(f)(iv), no Lender shall have an obligation to make any Revolving Loan, if (1) one or more of the applicable conditions precedent set forth in Section 3.3 are not satisfied on the requested Funding Date for the applicable Borrowing unless such condition has been waived, or (2) the requested Borrowing would exceed the Excess Availability on such Funding Date.

(ii)    Unless Agent receives notice from a Lender prior to 9:30 a.m. on the Business Day that is the requested Funding Date relative to a requested Borrowing as to which Agent has notified the Lenders of a requested Borrowing that such Lender will not make available as and when required hereunder to Agent for the account of the applicable Borrowers the amount of that Lender’s Pro Rata Share of the Borrowing, Agent may assume that each Lender has made or will make such amount

7

available to Agent in immediately available funds on the Funding Date and Agent may (but shall not be so required), in reliance upon such assumption, make available to the applicable Borrowers a corresponding amount. If, on the requested Funding Date, any Lender shall not have remitted the full amount that it is required to make available to Agent in immediately available funds and if Agent has made available to the applicable Borrowers such amount on the requested Funding Date, then such Lender shall make the amount of such Lender’s Pro Rata Share of the requested Borrowing available to Agent in immediately available funds, to the Agent’s Account, no later than 10:00 a.m. on the Business Day that is the first Business Day after the requested Funding Date (in which case, the interest accrued on such Lender’s portion of such Borrowing for the Funding Date shall be for Agent’s separate account). If any Lender shall not remit the full amount that it is required to make available to Agent in immediately available funds as and when required hereby and if Agent has made available to Borrowers such amount, then that Lender shall be obligated to immediately remit such amount to Agent, together with interest at the Defaulting Lender Rate for each day until the date on which such amount is so remitted. A notice submitted by Agent to any Lender with respect to amounts owing under this Section 2.3(e)(ii) shall be conclusive, absent manifest error. If the amount that a Lender is required to remit is made available to Agent, then such payment to Agent shall constitute such Lender’s Revolving Loan for all purposes of this Agreement. If such amount is not made available to Agent on the Business Day following the Funding Date, Agent will notify Borrowers of such failure to fund and, within one (1) Business Day after receipt of such notice, the Borrowers shall pay such amount to Agent for Agent’s account, together with interest thereon for each day elapsed since the date of such Borrowing, at a rate per annum equal to the interest rate applicable at the time to the Revolving Loans composing such Borrowing.

(f)    Protective Advances and Optional Overadvances.

(i)    Any contrary provision of this Agreement or any other Loan Document notwithstanding, but subject to Section 2.3(f)(iv), at any time after the occurrence and during the continuance of a Default or an Event of Default, or that any of the other applicable conditions precedent set forth in Section 3.3 are not satisfied, Agent hereby is authorized by the Borrowers and the Lenders, from time to time, in Agent’s Permitted Discretion, to make Tranche A Revolving Loans that are Base Rate Loans to, or for the benefit of, the Borrowers, on behalf of the Revolving Lenders, that Agent, in its Permitted Discretion, deems necessary or desirable (1) to preserve or protect the Collateral, or any portion thereof, or (2) to enhance the collectability or likelihood of repayment of the Obligations, so long as such Tranche A Revolving Loans do not cause Revolver Usage to exceed the Maximum Revolver Amount (the Revolving Loans described in this Section 2.3(f)(i) shall be referred to as “Protective Advances”). The Revolving Lenders shall participate on a pro rata basis in the Protective Advances outstanding from time to time. Required Lenders may at any time revoke Agent’s authority to make further Protective Advances by written notice to Agent. Agent shall use reasonable efforts to notify Parent of the existence of any Protective Advance on or about the date when made (it being understood that the failure to provide such notification to Parent shall have no effect on such Protective Advance).

(ii)    Any contrary provision of this Agreement or any other Loan Document notwithstanding, but subject to Section 2.3(f)(iv), if there is an Overadvance at any time, the excess amount shall be payable by the Borrowers within one (1) Business Day after receipt of demand from Agent, but all such Revolving Loans shall nevertheless constitute Obligations of the Borrowers secured by the applicable Collateral of the Loan Parties and entitled to all benefits of the Loan Documents. Agent may require the Revolving Lenders to honor requests for Overadvance Loans and to forbear from requiring the Borrowers to cure an Overadvance, (a) when no other Event of Default is known to the Agent, as long as (i) the Overadvance does not continue for more than 30 consecutive days (and no Overadvance may exist for at least five (5) consecutive days thereafter before further Overadvance Loans are required), and (ii) the Overadvance is not known by Agent to exceed 5.0% of the Maximum Revolver Amount and (b) regardless of whether an Event of Default exists, if Agent discovers an Overadvance not previously known by it to exist, as long as from the date of such discovery the Overadvance is not increased and does not continue for more than 30 consecutive days. In no event shall Overadvance Loans be required that would cause (x) Revolver Usage (including for this purpose, the aggregate principal amount of Overadvance Loans) to exceed the aggregate Revolver Commitments or (y) any Revolving Lenders’ Pro Rata Share of Revolver Usage (including, for this purpose, the aggregate

8

principal amount of Overadvance Loans) to exceed its Revolver Commitment. Any funding of an Overadvance Loan or sufferance of an Overadvance shall not constitute a waiver by Agent or Lenders of the Event of Default caused thereby. Agent shall use reasonable efforts to notify Parent of the existence of any Overadvance on or about the date when made (it being understood that the failure to provide such notification to Parent shall have no effect on such Overadvance).

(iii)    Each Protective Advance and each Overadvance (each, an “Extraordinary Advance”) shall be deemed to be a Revolving Loan hereunder, except that no Extraordinary Advance shall be eligible to be a LIBOR Rate Loan and, prior to Settlement therefor, all payments on the Extraordinary Advances shall be payable to Agent solely for its own account. The Extraordinary Advances shall be repayable within one (1) Business Day of demand thereof, secured by the Liens granted under the Loan Documents, constitute Obligations hereunder, and bear interest at the rate applicable from time to time to Revolving Loans that are Base Rate Loans.

(iv)    Notwithstanding anything contained in this Agreement or any other Loan Document to the contrary, no Extraordinary Advance may be made by Agent if such Extraordinary Advance would cause the aggregate principal amount of Extraordinary Advances outstanding to exceed an amount equal to 10% of the Maximum Revolver Amount.

(v)    The provisions of this Section 2.3(f) are for the exclusive benefit of Agent, Swing Lender, and the Lenders and are not intended to benefit Borrowers (or any other Loan Party) in any way.

(g)    Settlement.

(i)Obligations. It is agreed that each Revolving Lender’s funded portion of the Revolving Loans is intended by the Revolving Lenders to equal, at all times, such Lender’s Pro Rata Share of the outstanding Revolving Loans. Such agreement notwithstanding, the Agent, the Swing Lender, and the other Revolving Lenders agree (which agreement shall not be for the benefit of Borrowers) that in order to facilitate the administration of this Agreement and the other Loan Documents, Settlement among the Revolving Lenders as to the Revolving Loans, the Swing Loans, and the Extraordinary Advances shall take place on a periodic basis in accordance with the following provisions:

(A)    Agent shall request settlement (“Settlement”) with the Revolving Lenders on a weekly basis, or on a more frequent basis if so determined by Agent in its sole discretion (1) on behalf of the Swing Lender, with respect to the outstanding Swing Loans; provided that if any Tranche B Facility exists at such time, Swing Loans shall be settled as Tranche A Revolving Loans unless the outstanding principal amount of Tranche B Revolving Loans is less than the Tranche B Line Cap, in which case up to an amount equal to the Tranche B Line Cap minus the outstanding principal amount of Tranche B Revolving Loans of such Revolving Loans shall be settled as Tranche B Revolving Loans, and the remaining amount of such Revolving Loans shall be settled as Tranche A Revolving Loans, (2) for itself, with respect to the outstanding Extraordinary Advances, and (3) with respect to the Borrowers’ or any of their Subsidiaries’ payments or other amounts received, as to each by notifying the Revolving Lenders by telecopy, telephone, email or other electronic form of transmission, of such requested Settlement, no later than 2:00 p.m. on the Business Day immediately prior to the date of such requested Settlement (the date of such requested Settlement being the “Settlement Date”). Such notice of a Settlement Date shall include a summary statement of the amount of outstanding Revolving Loans, Swing Loans, and Extraordinary Advances for the period since the prior Settlement Date. Subject to the terms and conditions contained herein (including Section 2.3(i)): (y) if the amount of the Revolving Loans (including Swing Loans, and Extraordinary Advances) made by a Revolving Lender that is not a Defaulting Lender exceeds such Revolving Lender’s Pro Rata Share of the Revolving Loans (including Swing Loans, and Extraordinary Advances) as of a Settlement Date, then Agent shall, by no later than 12:00 p.m. on the Settlement Date, transfer in immediately available funds to a Deposit Account of such Revolving Lender (as such Revolving Lender may designate), an amount such that each such Revolving Lender shall, upon receipt of such amount, have as of the Settlement Date, its Pro Rata Share of the Revolving Loans (including Swing Loans, and Extraordinary Advances), and (z) if the amount of the

9

Revolving Loans (including Swing Loans, and Extraordinary Advances) made by a Revolving Lender is less than such Lender’s Pro Rata Share of the Revolving Loans (including Swing Loans, and Extraordinary Advances) as of a Settlement Date, such Revolving Lender shall no later than 12:00 p.m. on the Settlement Date transfer in immediately available funds to Agent’s Account, an amount such that each such Revolving Lender shall, upon transfer of such amount, have as of the Settlement Date, its Pro Rata Share of the Revolving Loans (including Swing Loans and Extraordinary Advances). Such amounts made available to Agent under clause (z) of the immediately preceding sentence shall be applied against the amounts of the Swing Loans or Extraordinary Advances and, together with the portion of such Swing Loans or Extraordinary Advances representing the Swing Lender’s Pro Rata Share thereof, shall constitute Revolving Loans of such Lenders. If any such amount is not made available to Agent by any Revolving Lender on the Settlement Date applicable thereto to the extent required by the terms hereof, Agent shall be entitled to recover for its account such amount on demand from such Revolving Lender together with interest thereon at the Defaulting Lender Rate.

(B)    In determining whether a Revolving Lender’s balance of the Revolving Loans, Swing Loans, and Extraordinary Advances is less than, equal to, or greater than such Revolving Lender’s Pro Rata Share of the Revolving Loans, Swing Loans, and Extraordinary Advances as of a Settlement Date, Agent shall, as part of the relevant Settlement, apply to such balance the portion of payments actually received in good funds by Agent with respect to principal, interest, fees payable by the Borrowers and allocable to the Revolving Lenders hereunder, and proceeds of Collateral securing the Obligations.

(C)    Between Settlement Dates, Agent, to the extent Extraordinary Advances or Swing Loans are outstanding, may pay over to Agent or the Swing Lender, as applicable, any payments or other amounts received by Agent, that in accordance with the terms of this Agreement would be applied to the reduction of the Revolving Loans, for application to the Extraordinary Advances or Swing Loans. Between Settlement Dates, Agent, to the extent no Extraordinary Advances or Swing Loans are outstanding, may pay over to the Swing Lender any payments or other amounts received by Agent, that in accordance with the terms of this Agreement would be applied to the reduction of the Revolving Loans, for application to the Swing Lender’s Pro Rata Share of the Revolving Loans. If, as of any Settlement Date, payments or other amounts of Parent and its Subsidiaries received since the then immediately preceding Settlement Date have been applied to the Swing Lender’s Pro Rata Share of the Revolving Loans other than to Swing Loans, as provided for in the previous sentence, the Swing Lender shall pay to Agent for the accounts of the Revolving Lenders, and Agent shall pay to the Revolving Lenders (other than a Defaulting Lender if Agent has implemented the provisions of Section 2.3(i)), to be applied to the outstanding Revolving Loans of such Revolving Lenders, an amount such that each such Revolving Lender shall, upon receipt of such amount, have, as of such Settlement Date, its Pro Rata Share of the Revolving Loans. During the period between Settlement Dates, the Swing Lender with respect to Swing Loans, Agent with respect to Extraordinary Advances, and each Revolving Lender with respect to the Revolving Loans other than Swing Loans and Extraordinary Advances, shall be entitled to interest at the applicable rate or rates payable under this Agreement on the daily amount of funds deployed by the Swing Lender, Agent, or the Revolving Lenders, as applicable.

(ii)Anything in this Section 2.3(g) to the contrary notwithstanding, in the event that a Lender is a Defaulting Lender, Agent shall be entitled to refrain from remitting settlement amounts to the Defaulting Lender and, instead, shall be entitled to elect to implement the provisions set forth in Section 2.3(i).

(h)    Notation. Agent, as a non-fiduciary agent for Borrowers, shall maintain a register (consistent with the Register required pursuant to Section 13.1(h)) showing the principal amount of the Revolving Loans owing to each Lender, including the Swing Loans owing to the Swing Lender, and Extraordinary Advances owing to Agent, and the interests therein of each Lender, from time to time and such register shall, absent manifest error, conclusively be presumed to be correct and accurate.

(i)    Defaulting Lenders.

10

(i)Generally. Notwithstanding the provisions of Section 2.4(b)(iv), Agent shall not be obligated to transfer to a Defaulting Lender any payments made by Borrowers (or any of them) to Agent for the Defaulting Lender’s benefit or any proceeds of Collateral that would otherwise be remitted hereunder to the Defaulting Lender, and, in the absence of such transfer to the Defaulting Lender, Agent shall transfer any such payments (A) first, to the Swing Lender to the extent of any Swing Loans that were made by the Swing Lender and that were required to be, but were not, paid by the Defaulting Lender; provided that if any Tranche B Facility exists at such time, Swing Loans shall be treated as Tranche A Revolving Loans unless the outstanding principal amount of Tranche B Revolving Loans is less than the Tranche B Line Cap, in which case up to an amount equal to the Tranche B Line Cap minus the outstanding principal amount of Tranche B Revolving Loans of such Revolving Loans shall be treated as Tranche B Revolving Loans, and the remaining amount of such Revolving Loans shall be treated as Tranche A Revolving Loans, (B) second, to Issuing Banks, to the extent of the portion of a Letter of Credit Disbursement that was required to be, but was not, paid by the Defaulting Lender, (C) third, to each Non-Defaulting Lender ratably in accordance with their Revolver Commitments (but, in each case, only to the extent that such Defaulting Lender’s portion of a Revolving Loan (or other funding obligation) was funded by such other Non-Defaulting Lender), (D) to a suspense account maintained by Agent, the proceeds of which shall be retained by Agent and may be made available to be re-advanced to or for the benefit of the Borrowers (upon the request of Borrowers and subject to the conditions set forth in Section 3.3) as if such Defaulting Lender had made its portion of Revolving Loans (or other funding obligations) hereunder, and (E) from and after the date on which all other Obligations have been paid in full, to such Defaulting Lender in accordance with tier (M) of Section 2.4(b)(iv). Subject to the foregoing, Agent may hold and, in its discretion, re-lend to the Borrowers for the account of such Defaulting Lender the amount of all such payments received and retained by Agent for the account of such Defaulting Lender. Solely for the purposes of voting or consenting to matters with respect to the Loan Documents (including the calculation of Pro Rata Share in connection therewith) and for the purpose of calculating the fee payable under Section 2.10(b), such Defaulting Lender shall be deemed not to be a “Lender” and such Lender’s Revolver Commitments shall be deemed to be zero; provided, that the foregoing shall not apply to any of the matters governed by Section 14.1(a)(i) through (iv) and (xii). The provisions of this Section 2.3(i) shall remain effective with respect to such Defaulting Lender until the earlier of (y) the date on which all of the Non-Defaulting Lenders, Agent, Issuing Banks, and Borrowers shall have waived, in writing, the application of this Section 2.3(i) to such Defaulting Lender, or (z) the date on which such Defaulting Lender makes payment of all amounts that it was obligated to fund hereunder, pays to Agent all amounts owing by Defaulting Lender in respect of the amounts that it was obligated to fund hereunder, and, if requested by Agent, provides adequate assurance of its ability to perform its future obligations hereunder (on which earlier date, so long as no Event of Default has occurred and is continuing, any remaining cash collateral held by Agent pursuant to Section 2.3(i)(ii) shall be released to the Borrowers). The operation of this Section 2.3(i) shall not be construed to increase or otherwise affect the Revolver Commitment of any Lender, to relieve or excuse the performance by such Defaulting Lender or any other Lender of its duties and obligations hereunder, or to relieve or excuse the performance by any Borrower of its duties and obligations hereunder to Agent, Issuing Banks, or to the Lenders other than such Defaulting Lender. Any failure by a Defaulting Lender to fund amounts that it was obligated to fund hereunder shall constitute a material breach by such Defaulting Lender of this Agreement and shall entitle Borrowers, at their option, upon written notice to Agent, to arrange for a substitute Lender to assume the Revolver Commitment of such Defaulting Lender, such substitute Lender to be reasonably acceptable to Agent. In connection with the arrangement of such a substitute Lender, the Defaulting Lender shall have no right to refuse to be replaced hereunder, and agrees to execute and deliver a completed form of Assignment and Acceptance in favor of the substitute Lender (and agrees that it shall be deemed to have executed and delivered such document if it fails to do so) subject only to being paid its share of the outstanding Obligations (other than Bank Product Obligations, but including (1) all interest, fees, and other amounts that may be due and payable in respect thereof, and (2) an assumption of its Pro Rata Share of its participation in the applicable Letters of Credit); provided, that, subject to Section 18.15, any such assumption of the Revolver Commitment of such Defaulting Lender shall not be deemed to constitute a waiver of any of the Lender Group’s or Borrowers’ rights or remedies against any such Defaulting Lender arising out of or in relation to such failure to fund. In the event of a direct conflict between the priority provisions of this Section 2.3(i) and any other provision contained in this Agreement or any other Loan Document, it is the intention of the parties hereto that such provisions be read together

11

and construed, to the fullest extent possible, to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot be resolved as aforesaid, the terms and provisions of this Section 2.3(i) shall control and govern.

(ii)Revolving Lenders as Defaulting Lenders. If any Swing Loan or Letter of Credit is outstanding at the time that a Revolving Lender becomes a Defaulting Lender then:

(A)    such Defaulting Lender’s Swing Loan Exposure and Letter of Credit Exposure shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Pro Rata Shares but only to the extent (x) the sum of all Non-Defaulting Lenders’ Revolving Loan Exposures plus such Defaulting Lender’s Swing Loan Exposure and Letter of Credit Exposure does not exceed the total of all Non-Defaulting Lenders’ Revolver Commitments, (y) no Non-Defaulting Lender’s Pro Rata Share of Revolver Usage exceeds its Revolver Commitment; provided that no Tranche A Revolving Lender shall be required to fund or participate in Tranche A Revolving Loans in excess of its Tranche A Revolver Commitment and no Tranche B Revolving Lender shall be required to fund or participate in Tranche B Revolving Loans in excess of its Tranche B Revolver Commitment and (z) the conditions set forth in Section 3.3 are satisfied at such time;

(B)    if the reallocation described in clause (A) above cannot, or can only partially, be effected, the Borrowers shall within one (1) Business Day following notice by the Agent (x) first, prepay such Defaulting Lender’s Swing Loan Exposure (after giving effect to any partial reallocation pursuant to clause (A) above) and (y) second, cash collateralize such Defaulting Lender’s Letter of Credit Exposure (after giving effect to any partial reallocation pursuant to clause (A) above), pursuant to a cash collateral agreement to be entered into in form and substance reasonably satisfactory to the Agent, for so long as such Letter of Credit Exposure is outstanding; provided, that the Borrowers shall not be obligated to cash collateralize any Defaulting Lender’s Letter of Credit Exposure if such Defaulting Lender is also an Issuing Bank;

(C)    if the Borrowers cash collateralize any portion of such Defaulting Lender’s Letter of Credit Exposure pursuant to this Section 2.3(i)(ii), the Borrowers shall not be required to pay any Letter of Credit Fees to Agent for the account of such Defaulting Lender pursuant to Section 2.6(b) with respect to such cash collateralized portion of such Defaulting Lender’s Letter of Credit Exposure during the period such Letter of Credit Exposure is cash collateralized;

(D)    to the extent the Letter of Credit Exposure of the Non-Defaulting Lenders is reallocated pursuant to this Section 2.3(i)(ii), then the Letter of Credit Fees payable to the Non-Defaulting Lenders pursuant to Section 2.6(b) shall be adjusted in accordance with such Non-Defaulting Lenders’ Letter of Credit Exposure;

(E)    to the extent any Defaulting Lender’s Letter of Credit Exposure is neither cash collateralized nor reallocated pursuant to this Section 2.3(i)(ii), then, without prejudice to any rights or remedies of any Issuing Bank or any Revolving Lender hereunder, all Letter of Credit Fees that would have otherwise been payable to such Defaulting Lender under Section 2.6(b) with respect to such portion of such Letter of Credit Exposure shall instead be payable to the applicable Issuing Bank until such portion of such Defaulting Lender’s Letter of Credit Exposure is cash collateralized or reallocated;

(F)    so long as any Revolving Lender is a Defaulting Lender, the Swing Lender shall not be required to make any Swing Loan and no Issuing Bank shall be required to issue, amend, or increase any Letter of Credit, in each case, to the extent (x) the Defaulting Lender’s Pro Rata Share of such Swing Loans or Letter of Credit cannot be reallocated pursuant to this Section 2.3(i)(ii) or (y) the Swing Lender or Issuing Banks, as applicable, have not otherwise entered into arrangements reasonably satisfactory to the Swing Lender or Issuing Banks, as applicable, and the Borrowers to eliminate the Swing Lender’s or Issuing Banks’ risk with respect to the Defaulting Lender’s participation in Swing Loans or Letters of Credit; and

12

(G)    Agent may release any cash collateral provided by the Borrowers pursuant to this Section 2.3(i)(ii) to any Issuing Bank and such Issuing Bank may apply any such cash collateral to the payment of such Defaulting Lender’s Pro Rata Share of any Letter of Credit Disbursement that is not reimbursed by the Borrowers pursuant to Section 2.11(d).

(iii)    [Reserved].

(j)    Independent Obligations. All Revolving Loans (other than Swing Loans and Extraordinary Advances) shall be made by the Lenders contemporaneously and in accordance with their Pro Rata Shares. The obligations of the Lenders under this Agreement to make Loans and to fund participations in Letters of Credit, Swing Loans and Extraordinary Advances are several (and not joint and several). It is understood that (i) no Lender shall be responsible for any failure by any other Lender to perform its obligation to make any Revolving Loan (or other extension of credit) hereunder, nor shall any Revolver Commitment of any Lender be increased or decreased as a result of any failure by any other Lender to perform its obligations hereunder, and (ii) no failure by any Lender to perform its obligations hereunder shall excuse any other Lender from its obligations hereunder.

2.4    Payments; Reductions of Commitments; Prepayments.

(a)    Payments by Borrowers.

(i)Except as otherwise expressly provided herein, all payments by the Borrowers (or any of them) shall be made to the Agent’s Account designated for the currency of the applicable payment and shall be made in immediately available funds, no later than 1:30 p.m. on the date specified herein. Any payment received by Agent later than 1:30 p.m. shall be deemed to have been received (unless Agent, in its sole discretion, elects to credit it on the date received) on the following Business Day and any applicable interest or fee shall continue to accrue until such following Business Day.

(ii)    Unless Agent receives notice from the Borrowers (or any of them) prior to the date on which any payment is due to the Lenders (or any of them) that such Borrowers will not make such payment in full as and when required, Agent may assume that such Borrowers have made (or will make) such payment in full to Agent on such date in immediately available funds and Agent may (but shall not be so required), in reliance upon such assumption, distribute to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent Borrowers (or any of them) do not make such payment in full to Agent on the date when due, each Lender severally shall repay to Agent on demand such amount distributed to such Lender, together with interest thereon at the Defaulting Lender Rate for each day from the date such amount is distributed to such Lender until the date repaid.

(b)    Apportionment and Application.

(i)    So long as no Application Event has occurred and is continuing and except as otherwise provided herein with respect to Defaulting Lenders, all principal and interest payments received by Agent shall be apportioned ratably among the Lenders (according to the unpaid principal balance of the portion of the Obligations to which such payments relate held by each Lender) and all payments of fees and expenses received by Agent (other than fees or expenses that are for Agent’s separate account or for the separate account of Issuing Banks) shall be apportioned ratably among the Lenders having a Pro Rata Share of the type of Revolver Commitment or portion of the Obligation to which a particular fee or expense relates.

(ii)    Subject to Section 2.4(b)(vii) and Section 2.4(d), all payments to be made hereunder by the Borrowers shall be remitted to Agent and all such payments, and all proceeds of Collateral securing the Obligations received by Agent, shall be applied, so long as no Application Event has occurred and is continuing and except as otherwise provided herein with respect to Defaulting Lenders, subject to the Intercreditor Agreement, to reduce the balance of the Revolving Loans

13

outstanding and, thereafter, to the Borrowers (to be wired to the Designated Account) or such other Person entitled thereto under applicable law.

(iii)    [Reserved].

(iv)    At any time that an Application Event has occurred and is continuing and except as otherwise provided herein with respect to Defaulting Lenders, subject to the Intercreditor Agreement, all payments remitted to Agent by the Borrowers and all proceeds of Collateral securing the Obligations received by Agent shall be applied as follows:

(A)    first, to pay any Lender Group Expenses (including cost or expense reimbursements) or indemnities then due to Agent under the Loan Documents in respect of the Obligations, until paid in full,

(B)    second, to pay any fees then due to Agent under the Loan Documents in respect of the Obligations until paid in full,

(C)    third, ratably to pay interest due in respect of all Protective Advances until paid in full,

(D)    fourth, ratably to pay the principal of all Protective Advances until paid in full,

(I)    ninth, to Agent, to be held by Agent, for the benefit of the Issuing Banks (and for the ratable benefit of each of the Revolving Lenders that have an obligation to pay to Agent, for the account of the Issuing Banks, a share of each Letter of Credit Disbursement in connection with each Letter of Credit), as cash collateral in an amount up to the sum of 103% of the Letter of Credit Usage (to the extent permitted by applicable law, such cash collateral shall be applied to the reimbursement of any Letter of Credit Disbursement as and when such disbursement occurs and, if a Letter of Credit expires undrawn, the cash collateral held by Agent in respect of such Letter of Credit shall, to the extent permitted by applicable law, be reapplied pursuant to this Section 2.4(b)(iv), beginning with tier (A) hereof),

(J)    tenth, ratably to pay interest accrued in respect of the Tranche A Revolving Loans under the Tranche A Facility (other than U.S. Protective Advances) until paid in full,

(K)    eleventh,

i.    ratably to pay the principal of all Tranche A Revolving Loans under the Tranche A Facility until paid in full, and

ii.    ratably up to the amount of the most recently established Pari Secured Hedge Reserves (after taking into account any amounts previously paid pursuant to this

14

clause ii during the continuation of the applicable Application Event), to a. the Hedge Providers with Pari Secured Hedge Obligations based upon amounts then certified by the applicable Hedge Provider to Agent (in form and substance satisfactory to Agent and in accordance with Section 18.5) to be due and payable to such Hedge Providers on account of Pari Secured Hedge Obligations, and b. with any balance to be paid to Agent, to be held by Agent, for the ratable benefit of the applicable Hedge Providers, as cash collateral (which cash collateral may be released by Agent to the applicable Hedge Provider and applied by such Hedge Provider to the payment or reimbursement of any amounts due and payable with respect to Pari Secured Hedge Obligations owed to the applicable Hedge Provider as and when such amounts first become due and payable and, if and at such time as all such Pari Secured Hedge Obligations are paid or otherwise satisfied in full, the cash collateral held by Agent in respect of such Pari Secured Hedge Obligations shall be reapplied pursuant to this Section 2.4(b)(iv), beginning with tier (A) hereof),

(N)    fourteenth, to pay any other Obligations other than Obligations owed to Defaulting Lenders (including being paid, ratably to the Bank Product Providers on account of all amounts then due and payable in respect of Bank Product Obligations (other than Pari Secured Hedge Obligations) based upon amounts then certified by the applicable Bank Product Providers to Agent (in form and substance reasonably satisfactory to Agent and in accordance with Section 18.5), with any balance to be paid to Agent, to be held by Agent, for the ratable benefit of the Bank Product Providers, as cash collateral (which cash collateral may be released by Agent to the applicable Bank Product Provider and applied by such Bank Product Provider to the payment or reimbursement of any amounts due and payable with respect to Bank Product Obligations owed to the applicable Bank Product Provider as and when such amounts first become due and payable and, if and at such time as all such Bank Product Obligations are paid or otherwise satisfied in full, the cash collateral held by Agent in respect of such Bank Product Obligations shall be reapplied pursuant to this Section 2.4(b)(iv), beginning with tier (A) hereof),

(O)    fifteenth, ratably to pay any Obligations owed to Defaulting Lenders; and

(P)    sixteenth, to the Borrowers (to be wired to the Designated Account) or such other Person entitled thereto under applicable law.

Notwithstanding anything to the contrary herein, the parties hereto agree that the unpaid principal of the Pari Secured Hedging Obligations (i.e., the termination payments that are due and payable thereunder after taking into account the effect of any legally enforceable netting arrangements (the “Net Termination Payments”)) shall be paid, ratably with the unpaid principal of Revolving Loans, pursuant to clause (K) above; provided that if on the date of any application of cash or proceeds in accordance with this Section 2.4(b)(iv), the aggregate Net Termination Payments due and payable with respect to such Pari Secured Hedge Obligations exceeds an amount equal to (x) $25,000,000, minus (y) the aggregate amount of Pari Secured Hedge Obligations previously paid pursuant to this Section 2.4(b)(iv) ((x) minus (y), the “Available Hedge Amount” at such date), then: (1) the Obligations payable pursuant to clause (K)(ii) shall be the Net Termination Payments due and payable with respect to Pari Secured Hedge Obligations in an aggregate amount equal to the Available Hedge Amount at such date (which Available Hedge Amount shall represent and be comprised of a ratable portion (the “Permitted Ratable Portion”) of the Net Termination Payments due and payable with respect to each Pari Secured Hedge Obligation), and (2) the portion of the termination payments due and payable (or that would be due and payable assuming a termination on such date of determination) with respect to each Pari Secured Hedge Obligation that is in excess of the Permitted Ratable Portion referred to in clause (1) (and is therefore not paid ratably with the unpaid principal of Revolving Loans pursuant to clause (K)) shall, for all purposes of this Section 2.4(b)(iv), be treated as and deemed to be Obligations of

15

a Bank Product Provider payable under clause (L) above, and shall be paid, ratably with the all other Obligations, pursuant to clause (L) above.

(v)     [Reserved].

(vi)    Agent promptly shall distribute to each Lender, pursuant to the applicable wire instructions received from each Lender in writing, such funds as it may be entitled to receive, subject to a Settlement delay as provided in Section 2.3(g).

(vii)    In each instance, so long as no Application Event has occurred and is continuing, Section 2.4(b)(iv) shall not apply to any payment made by the Borrowers (or any of them) to Agent and specified by such Borrowers to be for the payment of specific Obligations then due and payable (or prepayable) under any provision of this Agreement or any other Loan Document.

(viii)    For purposes of Section 2.4(b)(iv), “paid in full” of a type of Obligation means payment in cash or immediately available funds of all amounts owing on account of such type of Obligation, including interest accrued after the commencement of any Insolvency Proceeding, default interest, interest on interest, and expense reimbursements, irrespective of whether any of the foregoing would be or is allowed or disallowed in whole or in part in any Insolvency Proceeding.

(ix)    In the event of a direct conflict between the priority provisions of this Section 2.4 and any other provision contained in this Agreement or any other Loan Document, it is the intention of the parties hereto that such provisions be read together and construed, to the fullest extent possible, to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot be resolved as aforesaid, if the conflict relates to the provisions of Section 2.3(i) and this Section 2.4, then the provisions of Section 2.3(i) shall control and govern, and if otherwise, then the terms and provisions of this Section 2.4 shall control and govern.

(c)    Reduction of Commitments. The Revolver Commitments shall terminate on the Maturity Date. Borrowers may reduce the Revolver Commitments of either Class, without premium or penalty, to an amount not less than the sum of (A) the Revolver Usage of such Class as of such date, plus (B) the principal amount of all Revolving Loans of such Class not yet made as to which a request has been given by Borrowers under Section 2.3(a), plus (C) the amount of all Letters of Credit of such Class not yet issued as to which a request has been given by Borrowers pursuant to Section 2.11(a). Each such reduction shall be in an amount which is not less than $5,000,000 (unless the Revolver Commitments are being reduced to zero and the amount of the Revolver Commitments in effect immediately prior to such reduction are less than $5,000,000), shall be made by providing not less than five (5) Business Days prior written notice to Agent or such shorter period as the Agent may agree in its reasonable discretion, and shall be irrevocable; provided that such notice of termination may state that such notice is conditioned upon the effectiveness of other credit facilities or the closing of one or more securities offerings or other transactions, in which case such notice may be revoked by Borrowers (by notice to Agent from Parent on or prior to the specified effective date) if such condition is not satisfied. Once reduced, the Revolver Commitments may not be increased. Each such reduction of the Revolver Commitments shall reduce the Revolver Commitments of each Revolving Lender proportionately in accordance with its ratable share thereof.

(d)    Optional Prepayments. The Borrowers may prepay the principal of any Revolving Loan at any time in whole or in part, without premium or penalty (provided that no Tranche B Revolving Loan may be prepaid unless, prior to or simultaneously with such prepayment, all outstanding Tranche A Revolving Loans are repaid in full) upon not less than (x) three (3) Business Days prior written notice to Agent, in the case of LIBOR Rate Revolving Loan and (y) same day written notice to Agent, in the case of Base Rate Revolving Loans (each such notice to be irrevocable), provided that such notice may state that such notice is conditioned upon the effectiveness of other credit facilities or the closing of one or more securities offerings or other transactions, in which case such notice may be revoked by the Borrowers (by notice to Agent from Parent on or prior to the specified effective date) if such condition is

16

not satisfied; provided, further that no such notice shall be required during a Cash Dominion Trigger Period.

(e)    Mandatory Prepayments.

(i)    If, at any time and subject to Section 1.7(d), the Tranche A Revolver Usage on such date exceeds (A) the Tranche A Borrowing Base reflected in the Borrowing Base Certificate most recently delivered by Borrowers (and, in the case of the Tranche A Borrowing Base reflected in the Borrowing Base Certificate delivered on the Closing Date, subject to the last paragraph of the definition of “Tranche A Borrowing Base”) to Agent, less the aggregate amount of reserves, if any, established by Agent under Section 2.1(a) after the date of such Borrowing Base Certificate or (B) the Maximum Revolver Amount, then the Borrowers shall, within one (1) Business Day, prepay the Obligations in accordance with Section 2.4(f) in an aggregate amount equal to the amount of such excess.

(ii)    At any time during a Cash Dominion Trigger Period, the Agent shall have the right, subject to Section 2.4(b)(iv), to distribute and apply on a daily basis all amounts held in the Dominion Account to prepay the Obligations in accordance with Section 2.4(f).

(iii)    If, at any time and subject to Section 1.7(d), the Tranche B Revolving Loan Exposure on such date exceeds the Tranche B Line Cap then in effect, such excess shall (A) to the extent that the conditions to a Tranche A Revolving Loan in the amount of such excess under Section 3.3 are satisfied at such time, be deemed drawn under the Tranche A Facility pursuant to the Line Cap then in effect and (B) to the extent that the conditions to a Tranche A Revolving Loan in the amount of such excess under Section 3.3 are not satisfied at such time, give rise to a Reserve against the Tranche A Line Cap then in effect in an amount equal to such excess, and if the result causes the Tranche A Revolving Usage to exceed the Tranche A Line Cap then in effect the Borrowers shall immediately after demand, apply an amount equal to such excess to prepay the Loans and any interest accrued thereon, first, repay or prepay Swing Loans, second, repay or prepay Tranche A Revolving Borrowings, third, replace or Cash Collateralize outstanding Letters of Credit in an amount sufficient to eliminate such excess, and fourth, repay or prepay Tranche B Revolving Borrowings.

(f)    Application of Payments. Each prepayment pursuant to Section 2.4(e)(i), Section 2.4(e)(i) and Section 2.4(e)(iii) shall, (A) so long as no Application Event shall have occurred and be continuing, be applied, first, to the outstanding principal amount of the Tranche A Revolving Loans until paid in full, second, to cash collateralize the Letters of Credit in an amount equal to the sum of (x) 103% of the Letter of Credit Usage that is denominated in Dollars, and (y) 103% of the Letter of Credit Usage that is denominated in an Agreed Currency other than Dollars and third, to the outstanding Tranche B Revolving Loans, and (B) if an Application Event shall have occurred and be continuing, be applied in the manner set forth in Section 2.4(b)(iv).

(g)    Generally. Any mandatory prepayments required under Section 2.4(d) shall not result in a permanent reduction of the Revolver Commitments. All prepayments made pursuant to Section 2.4(d) or Section 2.4(d) shall be accompanied by accrued and unpaid interest on the amount so prepaid.

2.5    Promise to Pay; Promissory Notes.

(a)    The Borrowers agree to pay the Lender Group Expenses of Agent, the Issuing Banks, and the Revolving Lenders on the earlier of (1) the first day of the month following the date on which the applicable Lender Group Expenses were first incurred and invoiced or (2) the date on which demand therefor is made by Agent (it being acknowledged and agreed that any charging of such costs, expenses or Lender Group Expenses to the applicable Loan Account pursuant to the provisions of Section 2.6(d) shall be deemed to constitute a demand for payment thereof for the purposes of this subclause (ii)). The Borrowers promise to pay all of the Obligations (including principal, interest, premiums, if any, fees, costs,

17

(b)    [Reserved].

(c)    Any Lender may request that any portion of its Revolver Commitments or the Revolving Loans made by it be evidenced by one or more promissory notes. In such event, the Borrowers shall execute and deliver to such Lender or its registered assigns the requested promissory notes payable to such Lender in a form furnished by Agent and reasonably satisfactory to such Borrowers. Thereafter, the portion of the Revolver Commitments and Revolving Loans evidenced by such promissory notes and interest thereon shall at all times be represented by one or more promissory notes in such form payable to the payee named therein or its registered assigns.

2.6    Interest Rates and Letter of Credit Fee: Rates, Payments, and Calculations.

(a)    Interest Rates. Except as provided in Section 2.6(c), all Obligations (except for undrawn Letters of Credit) that have been charged to the applicable Loan Account pursuant to the terms hereof shall bear interest as follows:

(i)    if the relevant Obligation is a Revolving Loan that is a LIBOR Rate Loan, at a per annum rate equal to the LIBOR Rate plus the Applicable Margin, and

(ii)    if the relevant Obligation is a Revolving Loan that is a Base Rate Loan, at a per annum rate equal to the Base Rate plus the Applicable Margin.

(b)    Letter of Credit Fees. The Borrowers shall pay Agent (for the ratable benefit of the Revolving Lenders), a Letter of Credit fee (the “Letter of Credit Fee”) (which fee shall be in addition to the fronting fees and commissions, other fees, charges and expenses set forth in Section 2.11(l)) that shall accrue at a per annum rate equal to the Tranche A LIBOR Rate Margin times the undrawn amount of all outstanding Letters of Credit.

(c)    Default Rate. Upon the occurrence and during the continuation of an Event of Default,

(i)    the overdue Obligations shall bear interest at a per annum rate equal to two (2) percentage points above the per annum rate otherwise applicable hereunder, and

(ii)    the overdue Letter of Credit Fees shall be increased to two (2) percentage points above the per annum rate otherwise applicable hereunder.

Interest at the above referenced rate (the "Default Rate") shall be payable upon demand.

(d)    Payment.

(i)Except to the extent provided to the contrary in Section 2.4(g), Section 2.10, Section 2.11(l), and Section 2.13(a), (A) all interest, all Letter of Credit Fees, all Unused Line Fees and all other fees payable hereunder or under any of the other Loan Documents shall be due and payable, in arrears, on the first day of each quarter and on the Maturity Date, (B) [reserved], and (C) all costs and expenses payable hereunder or under any of the other Loan Documents, and all Lender Group Expenses shall be due and payable on the earlier of (x) the first day of the month following the date on which the applicable costs, expenses, or Lender Group Expenses were first incurred and invoiced, or (y) the date on which demand therefor is made by Agent (it being acknowledged and agreed that any charging of such costs, expenses or Lender Group Expenses to the applicable Loan Account pursuant to the provisions of the following clause (ii) shall be deemed to constitute a demand for payment thereof for the purposes of this subclause (y)).

(ii)    The Borrowers hereby authorize Agent, from time to time during any Cash Dominion Trigger Period, with prior notice to the Borrowers that the Agent is exercising its rights

18

under this Section 2.6(d)(ii) (provided that after delivery of such notice, no additional notice shall be required during such Cash Dominion Trigger Period), to charge to the Loan Account (A) on the first day of each quarter, all interest accrued during the prior quarter on the Revolving Loans hereunder, (B) on the first day of each quarter, all Letter of Credit Fees accrued or chargeable hereunder during the prior quarter, (C) as and when due and payable, all fees and costs provided for in Section 2.10(a) or (c), (D) on the first day of each quarter, the Unused Line Fee accrued during the prior quarter pursuant to Section 2.10(b), (E) as and when due and payable, all other fees payable hereunder or under any of the other Loan Documents, (F) as and when due and payable, the fronting fees and all commissions, other fees, charges and expenses provided for in Section 2.11(l), (G) as and when due and payable, all other Lender Group Expenses of Agent, the Issuing Banks, and the Revolving Lenders, and (H) as and when due and payable all other payment obligations payable under any Loan Document or any Bank Product Agreement (including any amounts due and payable to the Bank Product Providers in respect of Bank Products). All amounts (including interest, fees, costs, expenses, Lender Group Expenses, or other amounts payable hereunder or under any other Loan Document or under any Bank Product Agreement) charged to the Loan Account shall thereupon constitute Revolving Loans hereunder, shall constitute Obligations hereunder, and shall initially accrue interest at the rate then applicable to Revolving Loans that are Base Rate Loans (unless and until converted into LIBOR Rate Loans in accordance with the terms of this Agreement).

(e)    Computation. All interest and fees chargeable under the Loan Documents shall be computed on the basis of a 360-day year or, in the case of Base Rate Loans (or any fees or expenses based on the Base Rate), on the basis of a 365-day year or 366-day year, as applicable, in each case, for the actual number of days elapsed in the period during which the interest or fees accrue. In the event the Base Rate is changed from time to time hereafter, the rates of interest hereunder based upon the Base Rate automatically and immediately shall be increased or decreased by an amount equal to such change in the Base Rate.

(f)    Intent to Limit Charges to Maximum Lawful Rate. In no event shall the interest rate or rates payable under this Agreement, plus any other amounts paid in connection herewith, exceed the highest rate permissible under any law that a court of competent jurisdiction shall, in a final determination, deem applicable. Borrowers and the Lender Group, in executing and delivering this Agreement, intend legally to agree upon the rate or rates of interest and manner of payment stated within it; provided, that, anything contained herein to the contrary notwithstanding, if such rate or rates of interest or manner of payment exceeds the maximum allowable under applicable law, then, ipso facto, as of the date of this Agreement, the Borrowers are and shall be liable only for the payment of such maximum amount as is allowed by law, and payment received from any Borrowers in excess of such legal maximum, whenever received, shall be applied to reduce the principal balance of the Obligations to the extent of such excess.

2.7    Crediting Payments. The receipt of any payment item by Agent shall not be required to be considered a payment on account unless such payment item is a wire transfer of immediately available federal funds made to the Agent’s Account or unless and until such payment item is honored when presented for payment. Should any payment item not be honored when presented for payment, then Borrowers shall be deemed not to have made such payment and interest shall be calculated accordingly. Anything to the contrary contained herein notwithstanding, any payment item shall be deemed received by Agent only if it is received into the Agent’s Account on a Business Day on or before 1:30 p.m. If any payment item is received into the Agent’s Account on a non-Business Day or after 1:30 p.m. on a Business Day (unless Agent, in its sole discretion, elects to credit it on the date received), it shall be deemed to have been received by Agent as of the opening of business on the immediately following Business Day.

2.8    Designated Accounts. Agent is authorized to make the Revolving Loans, and Issuing Bank is authorized to issue the Letters of Credit, under this Agreement based upon electronic or other instructions received from anyone purporting to be an Authorized Person or, without instructions, if pursuant to Section 2.6(d)(ii). The Borrowers agree to establish and maintain the Designated Account with the Designated Account Bank for the purpose of receiving the proceeds of the Revolving Loans

19

requested by the Borrowers and made by Agent or the Revolving Lenders hereunder. Unless otherwise agreed by Agent and the Borrowers, any Revolving Loan or Swing Loan requested by the Borrowers and made by Agent or the Revolving Lenders hereunder shall be made to the Designated Account.

2.9    Maintenance of Loan Account; Statements of Obligations. Agent shall maintain an account on its books in the name of the Borrowers (the “Loan Account”) on which the Borrowers will be charged with all Revolving Loans (including Extraordinary Advances and Swing Loans) made by Agent, the Swing Lender, or the Revolving Lenders to the Borrowers or for the Borrowers’ account, the Letters of Credit issued or arranged by any Issuing Bank for the Borrowers’ account, and with all other payment Obligations hereunder or under the other Loan Documents, including, accrued interest, fees and expenses, and Lender Group Expenses. In accordance with Section 2.7, the Loan Account will be credited with all payments received by Agent from the Borrowers or for the Borrowers’ account. Agent shall make available to the Borrowers monthly statements regarding the Loan Account, including the principal amount of the Revolving Loans, interest accrued hereunder, fees accrued or charged hereunder or under the other Loan Documents, and a summary itemization of all charges and expenses constituting Lender Group Expenses accrued hereunder or under the other Loan Documents, and each such statement, absent manifest error, shall be conclusively presumed to be correct and accurate and constitute an account stated between the Borrowers and the Lender Group unless, within 30 days after Agent first makes such a statement available to the Borrowers, the Borrowers shall deliver to Agent written objection thereto describing the error or errors contained in such statement.

2.10    Fees

(a)    Agent Fees. The Borrowers shall pay to Agent, for the account of Agent, the “ABL Agency Fee” set forth in Section 1 of the Fee Letter, which ABL Agency Fee shall be earned, due and payable to Agent quarterly in advance commencing on the Closing Date and on the first calendar day of the month after each quarter thereafter for so long as this Agreement is in effect.

(b)    Unused Line Fees. The Borrowers shall pay to Agent, for the ratable account of the Revolving Lenders, an unused line fee (the “Unused Line Fee”) in an amount equal to the Applicable Unused Line Fee Percentage per annum times the result of (i) the aggregate amount of the Revolver Commitments, less (ii) the average amount of the Revolver Usage during the immediately preceding quarter (or portion thereof), which Unused Line Fee shall be due and payable, in arrears, on the first day of each quarter from and after the Closing Date up to the first day of the quarter prior to the date on which the Obligations are paid in full and on the date on which the Obligations are paid in full.

(c)    Field Examination and Other Fees. The Borrowers shall pay to Agent, Agent’s then standard field examination, appraisal, and valuation fees and charges (including charges of its internal examination and appraisal groups), as and when incurred or chargeable, the fees or charges paid or incurred by Agent (including allocated costs of employees of Agent) to perform field examinations of Parent or its Subsidiaries, to establish electronic collateral reporting systems, to appraise the Collateral, or any portion thereof, or to assess Parent’s or its Subsidiaries’ business valuation; provided, that so long as no Event of Default and no Field Examination/Appraisal Triggering Event shall have occurred and be continuing, the Borrowers shall not be obligated to reimburse Agent for more than one (1) field examination, one (1) appraisal of the Collateral consisting of inventory, one (1) appraisal of the Collateral consisting of equipment, and one (1) business valuation during any calendar year; provided,further that (i) if a Field Examination/Appraisal Triggering Event occurs in any calendar year, the limits in the immediately preceding proviso shall each be increased to two (2) and (ii) during the existence and continuance of an Event of Default, the limits in the immediately preceding proviso shall each be increased to four (4).

2.11    Letters of Credit.

(a)    Subject to the terms and conditions of this Agreement, upon the request of the Borrowers made in accordance herewith, during the period from the Closing Date until the Letter of Credit Expiration Date, each Issuing Bank agrees to issue a requested Letter of Credit for the account of the

20

Borrowers (which issuance, subject to Section 2.11(h), may be for an Account Party), it being agreed that each Issuing Bank shall only be required to issue standby Letters of Credit unless it otherwise agrees (in its sole discretion). By submitting a request to an Issuing Bank for the issuance of a Letter of Credit, the Borrowers shall be deemed to have requested that such Issuing Bank issue the requested Letter of Credit. Each request for the issuance of a Letter of Credit, or the amendment, renewal, or extension of any outstanding Letter of Credit, shall be irrevocable and shall be made in writing by an Authorized Person and delivered to the applicable Issuing Bank via telefacsimile or other electronic method of transmission reasonably acceptable to such Issuing Bank and at least three (3) Business Days (or such shorter period as agreed by the applicable Issuing Bank) in advance of the requested date of issuance, amendment, renewal, or extension. Each such request shall be in form and substance reasonably satisfactory to such Issuing Bank and (i) shall specify (A) the amount and applicable Agreed Currency of such Letter of Credit, (B) the date of issuance, amendment, renewal, or extension of such Letter of Credit, (C) the proposed expiration date of such Letter of Credit, (D) the name and address of the beneficiary of the Letter of Credit, and (E) such other information (including, the conditions to drawing, and, in the case of an amendment, renewal, or extension, identification of the Letter of Credit to be so amended, renewed, or extended) as shall be reasonably necessary to prepare, amend, renew, or extend such Letter of Credit, and (ii) shall be accompanied by such Issuer Documents as Agent or such Issuing Bank may reasonably request or require, to the extent that such requests or requirements are consistent with the Issuer Documents that such Issuing Bank generally requests for Letters of Credit in similar circumstances. The applicable Issuing Bank’s records of the content of any such request will be conclusive, absent manifest error. Unless otherwise specified, all references herein to the amount of a Letter of Credit at any time shall be deemed to mean the maximum face amount of such Letter of Credit after giving effect to all increases thereof contemplated by such Letter of Credit related thereto, whether or not such maximum face amount is in effect at such time.

(b)    No Issuing Bank shall issue a Letter of Credit if any of the following would result after giving effect to the requested issuance:

(i)    the Letter of Credit Usage would exceed the Letter of Credit Sublimit, or the aggregate undrawn amount of all outstanding Letters of Credit issued by such Issuing Bank would exceed the Letter of Credit Sublimit with respect to such Issuing Bank,

(ii)    the Letter of Credit Usage would exceed the Maximum Revolver Amount less the sum of the outstanding principal amount of Revolving Loans (including Swing Loans) at such time,

(iii)    the Letter of Credit Usage would exceed the Tranche A Borrowing Base at such time less the sum of the outstanding principal amount of Tranche A Revolving Loans (including Swing Loans) at such time, or

(iv)    the expiration date of such requested Letter of Credit would occur after the earlier to occur of the date that is 12 months after the date of issuance of such Letter of Credit and the Letter of Credit Expiration Date, unless such Issuing Bank and the Agent have approved such expiration date (it being understood that the obligation of Revolving Lenders to fund participations in Letters of Credit shall expire immediately following the Maturity Date (for this purpose, pursuant to clause (a) of the definition thereof)).

In addition, no Issuing Bank shall issue or be obligated to issue any Letter of Credit if it has actual knowledge that one or more of the applicable conditions precedent set forth in Section 3 is not satisfied on the requested Funding Date. On the Maturity Date, the Borrowers shall provide Letter of Credit Collateralization to Agent (or make other arrangements acceptable to the applicable Issuing Bank) to be held as security for Borrowers’ reimbursement obligations in respect of drawings that may subsequently occur under issued and outstanding Letters of Credit.

(c)    In the event there is a Defaulting Lender as of the date of any request for the issuance of a Letter of Credit, no Issuing Bank shall be required to issue or arrange for such Letter of

21

Credit to the extent (i) the Defaulting Lender’s Letter of Credit Exposure with respect to such Letter of Credit may not be reallocated pursuant to Section 2.3(i)(ii), or (ii) such Issuing Bank has not otherwise entered into arrangements reasonably satisfactory to it and the Borrowers to eliminate such Issuing Bank’s risk with respect to the participation in such Letter of Credit of the Defaulting Lender, which arrangements may include the Borrowers cash collateralizing such Defaulting Lender’s Letter of Credit Exposure in accordance with Section 2.3(i)(ii). Additionally, no Issuing Bank shall have any obligation to issue a Letter of Credit if (A) any order, judgment, or decree of any Governmental Authority or arbitrator shall, by its terms, purport to enjoin or restrain such Issuing Bank from issuing such Letter of Credit, or any law applicable to such Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such Issuing Bank shall prohibit or request that such Issuing Bank refrain from the issuance of letters of credit generally or such Letter of Credit in particular, (B) the issuance of such Letter of Credit would violate one or more policies of such Issuing Bank applicable to letters of credit generally, or (C) if amounts demanded to be paid under any Letter of Credit will or may not be in an Agreed Currency.

(d)    Any Issuing Bank (other than Bank of America or any of its Affiliates) shall notify Agent in writing no later than the Business Day immediately following the Business Day on which such Issuing Bank receives a request for issuance of any Letter of Credit. The applicable Issuing Bank will not issue any requested Letter of Credit if it receives written notice from the Agent (with a copy to Parent) that the proposed Letter of Credit would cause an Overadvance to occur. Each Letter of Credit shall be in form and substance reasonably acceptable to the applicable Issuing Bank, including the requirement that the amounts payable thereunder must be payable in an Agreed Currency. If an Issuing Bank makes a payment under a Letter of Credit, the Borrowers shall pay to Agent an amount equal to the applicable Letter of Credit Disbursement in the same currency as such Letter of Credit (i) within one (1) Business Day after such Letter of Credit Disbursement in the case of Letters of Credit denominated in Dollars and (ii) within two (2) Business Days after such Letter of Credit Disbursement in the case of Letters of Credit denominated in an Agreed Currency other than Dollars is made and, in the absence of such payment, the amount of such Letter of Credit Disbursement (or, in the case of a Letter of Credit Disbursement in an Agreed Currency other than Dollars, the Agreed Currency Equivalent of such Letter of Credit Disbursement) immediately and automatically shall be deemed to be a Revolving Loan hereunder (notwithstanding any failure to satisfy any condition precedent set forth in Section 3) and, initially, shall bear interest at the rate then applicable to Revolving Loans that are Base Rate Loans. If a Letter of Credit Disbursement is deemed to be a Revolving Loan hereunder, the Borrowers’ obligation to pay the amount of such Letter of Credit Disbursement to the applicable Issuing Bank shall be automatically converted into an obligation to pay the resulting Revolving Loan. Promptly following receipt by Agent of any payment from the Borrowers pursuant to this paragraph, Agent shall distribute such payment to the applicable Issuing Bank or, to the extent that Revolving Lenders have made payments pursuant to Section 2.11(e) to reimburse the applicable Issuing Bank, then to such Revolving Lenders and such Issuing Bank as their interests may appear.

(e)    Promptly following receipt of a notice of a Letter of Credit Disbursement pursuant to Section 2.11(d), each Revolving Lender agrees to fund its Pro Rata Share of any Revolving Loan deemed made pursuant to Section 2.11(d) on the same terms and conditions as if the Borrowers had requested the amount thereof as a Revolving Loan and Agent shall promptly pay to the applicable Issuing Bank the amounts so received by it from the Revolving Lenders; provided that in the case of Letters of Credit denominated in an Agreed Currency other than Dollars, each Revolving Lender shall fund in Dollars its Pro Rata Share of the amount equal to the Agreed Currency Equivalent of such Letter of Credit Disbursement amount. By the issuance of a Letter of Credit (or an amendment, renewal, or extension of a Letter of Credit) and without any further action on the part of any Issuing Bank or the Revolving Lenders, the applicable Issuing Bank shall be deemed to have granted to each Revolving Lender, and each Revolving Lender shall be deemed to have purchased, a participation in each Letter of Credit issued by such Issuing Bank, in an amount equal to its Pro Rata Share of such Letter of Credit, and each such Revolving Lender agrees to pay to Agent, for the account of such Issuing Bank, such Revolving Lender’s Pro Rata Share of any Letter of Credit Disbursement made by such Issuing Bank under the applicable Letter of Credit. In consideration and in furtherance of the foregoing, each Revolving Lender hereby absolutely and unconditionally agrees to pay to Agent, for the account of the applicable Issuing Bank,

22

such Revolving Lender’s Pro Rata Share of each Letter of Credit Disbursement made by such Issuing Bank and not reimbursed by the Borrowers on the date due as provided in Section 2.11(d), or of any reimbursement payment that is required to be refunded (or that Agent or the applicable Issuing Bank elects, based upon the advice of counsel, to refund) to the Borrowers for any reason. Each Revolving Lender acknowledges and agrees that its obligation to deliver to Agent, for the account of the applicable Issuing Bank, an amount equal to its respective Pro Rata Share of each Letter of Credit Disbursement pursuant to this Section 2.11(e) shall be absolute and unconditional and such remittance shall be made notwithstanding the occurrence or continuation of an Event of Default or Default or the failure to satisfy any condition set forth in Section 3.

(f)    Each Borrower agrees to indemnify, defend and hold harmless each member of the Lender Group (including each Issuing Bank and its branches, Affiliates, and correspondents) and each such Person’s respective directors, officers, employees, attorneys and agents (each, including each Issuing Bank, a “Letter of Credit Related Person”) (to the fullest extent permitted by law) from and against any and all claims, demands, suits, actions, investigations, proceedings, liabilities, fines, costs, penalties, and damages, and all reasonable fees and disbursements of one counsel in each relevant jurisdiction (and, solely in the case of an actual or perceived conflict of interest, one additional counsel to each group of affected persons similarly situated) and all other reasonable and documented costs and out-of-pocket expenses actually incurred in connection therewith or in connection with the enforcement of this indemnification (as and when they are incurred and irrespective of whether suit is brought), which may be incurred by or awarded against any Letter of Credit Related Person (other than any Taxes that are governed by Section 17, or Excluded Taxes) (the “Letter of Credit Indemnified Costs”), and which arise out of or in connection with, or as a result of this Agreement, any Letter of Credit, any Issuer Document, or any Drawing Document referred to in or related to any Letter of Credit, or any action or proceeding arising out of any of the foregoing (whether administrative, judicial or in connection with arbitration); in each case, including that resulting from the Letter of Credit Related Person’s own negligence (other than resulting from such Person’s bad faith or willful misconduct or constituting gross negligence); provided, however, that such indemnity shall not be available to any Letter of Credit Related Person claiming indemnification to the extent that such Letter of Credit Indemnified Costs may be finally determined in a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the bad faith, gross negligence or willful misconduct of the Letter of Credit Related Person claiming indemnity. This indemnification provision shall survive termination of this Agreement and all Letters of Credit.

(g)    The liability of each Issuing Bank (or any other Letter of Credit Related Person) under, in connection with or arising out of any Letter of Credit (or pre-advice), regardless of the form or legal grounds of the action or proceeding, shall be limited to direct damages suffered by the Borrowers that result from such Issuing Bank’s bad faith, gross negligence or willful misconduct in (i) honoring a presentation under a Letter of Credit that on its face does not at least substantially comply with the terms and conditions of such Letter of Credit, (ii) failing to honor a presentation under a Letter of Credit that strictly complies with the terms and conditions of such Letter of Credit or (iii) retaining Drawing Documents presented under a Letter of Credit. Each Issuing Bank shall be deemed to have acted with due diligence and reasonable care if such Issuing Bank’s conduct is in accordance with Standard Letter of Credit Practice or in accordance with this Agreement. The Borrowers’ aggregate remedies against each Issuing Bank and any Letter of Credit Related Person for wrongfully honoring a presentation under any Letter of Credit or wrongfully retaining honored Drawing Documents shall in no event exceed the aggregate amount paid by the Borrowers to the applicable Issuing Bank in respect of the honored presentation in connection with such Letter of Credit under Section 2.11(d), plus interest at the rate then applicable to Base Rate Loans hereunder.

(h)    The Borrowers are responsible for the final text of the Letter of Credit as issued by any Issuing Bank, irrespective of any assistance such Issuing Bank may provide such as drafting or recommending text or by such Issuing Bank’s use or refusal to use text submitted by the Borrowers. Prior to the issuance of a Letter of Credit, the Borrowers understand that the final form of any Letter of Credit may be subject to such revisions and changes as are deemed necessary or appropriate by the applicable Issuing Bank, and the Borrowers hereby consent to such revisions and change so long as they are (1) not materially different from the application executed in connection therewith and (2) are in accordance with

23

international standard banking practice. The Borrowers are solely responsible for the suitability of the Letter of Credit for the Borrowers’ purposes. If the Borrowers request any Issuing Bank to issue a Letter of Credit for an affiliated or unaffiliated third party (an “Account Party”), (i) such Account Party shall have no rights against such Issuing Bank; (ii) the Borrowers shall be responsible for the application and obligations under this Agreement; and (iii) communications (including notices) related to the respective Letter of Credit shall be among such Issuing Bank and the Borrowers. The Borrowers will examine the copy of the Letter of Credit and any other document sent by each Issuing Bank in connection therewith and shall promptly notify such Issuing Bank (not later than three (3) Business Days following the Borrowers’ receipt of documents from such Issuing Bank) of any non-compliance with the Borrowers’ instructions and of any discrepancy in any document under any presentment or other irregularity. The Borrowers understand and agree that no Issuing Bank is required to extend the expiration date of any Letter of Credit for any reason. With respect to any Letter of Credit containing an “automatic amendment” to extend the expiration date of such Letter of Credit for additional consecutive periods of 12 months (but in no event shall the expiration date extend beyond the Letter of Credit Expiration Date unless such Issuing Bank and the Agent have approved such expiration date (it being understood that the obligation of Revolving Lenders to fund participations in Letters of Credit shall expire immediately following the Maturity Date (for this purpose, pursuant to clause (a) of the definition thereof)), any Issuing Bank, in its sole and absolute discretion, may give notice of nonrenewal of such Letter of Credit and, if the Borrowers do not at any time want such Letter of Credit to be renewed, the Borrowers will so notify Agent and the applicable Issuing Bank at least 30 calendar days (or such later date as agreed to by the applicable Issuing Bank) before such Issuing Bank is required to notify the beneficiary of such Letter of Credit or any advising bank of such nonrenewal pursuant to the terms of such Letter of Credit.

(i)    The Borrowers’ reimbursement and payment obligations under this Section are absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever, provided, however, that subject to Section 2.11(g) above, the foregoing shall not release any Issuing Bank from such liability to the Borrowers as may be finally determined in a final, non-appealable judgment of a court of competent jurisdiction against such Issuing Bank following reimbursement or payment of the obligations and liabilities, including reimbursement and other payment obligations, of the Borrowers to such Issuing Bank arising under, or in connection with, this Section 2.11 or any Letter of Credit.

(j)    Without limiting any other provision of this Agreement, each Issuing Bank and each other Letter of Credit Related Person (if applicable) shall not be responsible to the Borrowers for, and no Issuing Bank’s rights and remedies against the Borrowers and the obligation of the Borrowers to reimburse each Issuing Bank for each drawing under each Letter of Credit shall be impaired by:

(i)    honor of a presentation under any Letter of Credit that on its face substantially complies with the terms and conditions of such Letter of Credit, even if the Letter of Credit requires strict compliance by the beneficiary;

(ii)    honor of a presentation of any Drawing Document that appears on its face to have been signed, presented or issued (A) by any purported successor or transferee of any beneficiary or other Person required to sign, present or issue such Drawing Document or (B) under a new name of the beneficiary;

(iii)    acceptance as a draft of any written or electronic demand or request for payment under a Letter of Credit, even if non-negotiable or not in the form of a draft or notwithstanding any requirement that such draft, demand or request bear any or adequate reference to a Letter of Credit;

(iv)    the identity or authority of any presenter or signer of any Drawing Document or the form, accuracy, genuineness or legal effect of any Drawing Document (other than the applicable Issuing Bank’s determination that such Drawing Document appears on its face substantially to comply with the terms and conditions of a Letter of Credit);

24

(v)    acting upon any instruction or request relative to a Letter of Credit or requested a Letter of Credit that an Issuing Bank in good faith believes to have been given by a Person authorized to give such instruction or request;

(vi)    any errors, omissions, interruptions or delays in transmission or delivery of any message, advice or document (regardless of how sent or transmitted) or for errors in interpretation of technical terms or in translation or any delay in giving or failing to give notice to the Borrowers;

(vii)    any acts, omissions or fraud by, or the insolvency of, any beneficiary, any nominated person or entity or any other Person or any breach of contract between any beneficiary and any Borrower or any of the parties to the underlying transaction to which the Letter of Credit relates;

(viii)    assertion or waiver of any provision of the ISP or UCP that primarily benefits an issuer of a Letter of Credit, including any requirement that any Drawing Document be presented to it at a particular hour or place;

(ix)    payment to any presenting bank (designated or permitted by the terms of the applicable Letter of Credit) claiming that it rightfully honored or is entitled to reimbursement or indemnity under Standard Letter of Credit Practice applicable to it;

(x)    acting or failing to act as required or permitted under Standard Letter of Credit Practice applicable to where Issuing Bank has issued, confirmed, advised or negotiated such Letter of Credit, as the case may be;

(xi)    honor of a presentation after the expiration date of any Letter of Credit notwithstanding that a presentation was made prior to such expiration date and dishonored by the applicable Issuing Bank if subsequently Issuing Bank or any court or other finder of fact determines such presentation should have been honored;

(xii)    dishonor of any presentation that does not strictly comply or that is fraudulent, forged or otherwise not entitled to honor; or

(xiii)    honor of a presentation that is subsequently determined by the applicable Issuing Bank to have been made in violation of international, federal, state or local restrictions on the transaction of business with certain prohibited Persons.

(k)    [Reserved.]

(l)    The Borrowers shall pay immediately upon demand to Agent for the account of the applicable Issuing Bank as non-refundable fees, commissions, and charges (it being acknowledged and agreed that any charging of such fees, commissions, and charges to the Loan Account pursuant to the provisions of Section 2.6(d)(ii) shall be deemed to constitute a demand for payment thereof for the purposes of this Section 2.11(l)): (1) a fronting fee which shall be imposed by the applicable Issuing Bank upon the issuance of each Letter of Credit of 0.125% per annum of the face amount thereof, which fee shall be payable quarterly in arrears, on the first day of each quarter, and on maturity, plus (2) any and all other customary commissions, fees and charges then in effect imposed by, and any and all reasonable and documented out-of-pocket expenses incurred by, the applicable Issuing Bank, or by any adviser, confirming institution or entity or other nominated person, relating to Letters of Credit, at the time of issuance of any Letter of Credit and upon the occurrence of any other activity with respect to any Letter of Credit (including, transfers, assignments of proceeds, amendments, drawings, extensions or cancellations) which charges shall be paid as and when incurred.

(m)    If by reason of (x) any Change in Law, or (y) compliance by any Issuing Bank or any other member of the Lender Group with any direction, request, or requirement (irrespective of whether having the force of law) of any Governmental Authority or monetary authority including, Regulation D of the Board of Governors as from time to time in effect (and any successor thereto):

25

(i)    any reserve, deposit, or similar requirement is or shall be imposed or modified in respect of any Letter of Credit issued or caused to be issued hereunder or hereby, or

(ii)    there shall be imposed on any Issuing Bank or any other member of the Lender Group any other condition regarding any Letter of Credit, or

(iii)    there shall be imposed on any member of the Lender Group or Agent any Taxes (other than (A) Indemnified Taxes and (B) Excluded Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto,

and the result of the foregoing is to increase, directly or indirectly, the cost to any Issuing Bank or any other member of the Lender Group of issuing, making, participating in, or maintaining any Letter of Credit or to reduce the amount receivable in respect thereof, then, and in any such case, Agent may, at any time within 180 days after the additional cost is incurred or the amount received is reduced, notify the Borrowers, and the Borrowers shall pay within 30 days after demand therefor, such amounts as Agent may specify to be necessary to compensate the applicable Issuing Bank or any other member of the Lender Group for such additional cost or reduced receipt, together with interest on such amount from the date of such demand until payment in full thereof at the rate then applicable to Base Rate Loans hereunder; provided, that (a) the Borrowers shall not be required to provide any compensation pursuant to this Section 2.11(m) for any such amounts incurred more than 180 days prior to the date on which the demand for payment of such amounts is first made to the Borrowers, and (b) if an event or circumstance giving rise to such amounts is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. The determination by Agent of any amount due pursuant to this Section 2.11(m), as set forth in a certificate setting forth the calculation thereof in reasonable detail, shall, in the absence of manifest or demonstrable error, be final and conclusive and binding on all of the parties hereto.

(n)    Unless otherwise expressly agreed by the applicable Issuing Bank and the Borrowers when a Letter of Credit is issued, (i) the rules of the ISP and the UCP shall apply to each standby Letter of Credit, and (ii) the rules of the UCP shall apply to each commercial Letter of Credit.

(o)    In the event of a direct conflict between the provisions of this Section 2.11 and any provision contained in any Issuer Document, it is the intention of the parties hereto that such provisions be read together and construed, to the fullest extent possible, to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot be resolved as aforesaid, the terms and provisions of this Section 2.11 shall control and govern.

(p)    The provisions of this Section 2.11 shall survive the termination of this Agreement and the repayment in full of the Obligations with respect to any Letters of Credit that remain outstanding thereafter.

(q)    Notwithstanding anything to the contrary contained herein, any Issuing Bank may, upon thirty (30) days’ notice to the Borrowers and the Lenders, resign as an Issuing Bank; provided that on or prior to the expiration of such 30-day period with respect to such resignation, the relevant Issuing Bank shall have identified a successor Issuing Bank reasonably acceptable to the Borrowers willing to accept its appointment as successor Issuing Bank. In the event of any such resignation of an Issuing Bank, the Borrowers shall be entitled to appoint from among the Lenders willing to accept such appointment a successor Issuing Bank hereunder; provided that no failure by the Borrowers to appoint any such successor shall affect the resignation of the relevant Issuing Bank, as the case may be, except as expressly provided above. If an Issuing Bank resigns as an Issuing Bank, it shall retain all the rights and obligations of an Issuing Bank hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as an Issuing Bank and all obligations with respect thereto.

26

(r)    Each Existing Letter of Credit shall be assumed by the Borrowers and deemed a Letter of Credit issued hereunder for account of the Borrowers for all purposes under this Agreement without need for any further action by the Borrowers or any other Person, and shall be subject to and governed by the terms and conditions of this Agreement. On the Second Amendment Effective Date, each Existing Letter of Credit, to the extent outstanding, shall automatically and without further action by the parties thereto be deemed converted to Letters of Credit issued pursuant to this Section 2.11 for the account of the Borrowers and subject to the provisions hereof.

2.12    [Reserved].

2.13    LIBOR Option.

(a)    Interest and Interest Payment Dates. In lieu of having interest charged at the rate based upon the Base Rate, the Borrowers shall have the option, subject to Section 2.13(b) below (the “LIBOR Option”) to have interest on all or a portion of the Revolving Loans be charged (whether at the time when made (unless otherwise provided herein), upon conversion from a Base Rate Loan to a LIBOR Rate Loan, or upon continuation of a LIBOR Rate Loan as a LIBOR Rate Loan) at a rate of interest based upon the LIBOR Rate. Interest on LIBOR Rate Loans shall be payable on the earliest of (i) the last day of the Interest Period applicable thereto; provided, that, subject to the following clauses (ii) and (iii), in the case of any Interest Period greater than three (3) months in duration, interest shall be payable at three (3) month intervals after the commencement of the applicable Interest Period and on the last day of such Interest Period), (ii) the date on which all or any portion of the Obligations are accelerated pursuant to the terms hereof, or (iii) the date on which this Agreement is terminated pursuant to the terms hereof. On the last day of each applicable Interest Period, unless Borrowers have properly exercised the LIBOR Option with respect thereto, the interest rate applicable to such LIBOR Rate Loan automatically shall convert to the rate of interest then applicable to Base Rate Loans of the same type hereunder. At any time that an Event of Default has occurred and is continuing, at the written election of the Required Lenders, no Borrower shall have the option to request that any Revolving Loans bear interest at a rate based upon the LIBOR Rate.

(b)    LIBOR Election.

(i)Borrowers may, at any time and from time to time, so long as no Event of Default has occurred and is continuing, and the Required Lenders have not elected pursuant to Section 2.13(a) to prohibit LIBOR Rate Loans, elect to exercise the LIBOR Option by notifying Agent prior to 11:00 a.m. at least three (3) Business Days prior to the commencement of the proposed Interest Period (the “LIBOR Deadline”). Notice of Borrowers’ election of the LIBOR Option for a permitted portion of the Revolving Loans and an Interest Period pursuant to this Section shall be made by delivery to Agent of a LIBOR Notice received by Agent before the LIBOR Deadline, or by electronic notice received by Agent before the LIBOR Deadline (to be confirmed by delivery to Agent of a LIBOR Notice received by Agent prior to 5:00 p.m. on the same day). Promptly upon its receipt of each such LIBOR Notice, Agent shall provide a copy thereof to each of the affected Lenders. Each LIBOR Notice shall be irrevocable and binding on the Borrowers.

(ii)    In connection with each LIBOR Rate Loan, each Borrower of such Revolving Loan shall indemnify, defend, and hold Agent and the Lenders harmless against any actual loss, cost, or expense incurred by Agent or any Lender as a result of (A) the payment of any principal of any applicable LIBOR Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (B) the conversion of any LIBOR Rate Loan other than on the last day of the Interest Period applicable thereto, or (C) the failure to borrow, convert, continue or prepay any LIBOR Rate Loan on a date that is not the last day of the Interest Period or the date otherwise specified in any LIBOR Notice delivered pursuant hereto (such losses, costs, or expenses, “Funding Losses”). A certificate of Agent or a Lender delivered to the Borrowers setting forth in reasonable detail any amount or amounts that Agent or such Lender is entitled to receive pursuant to this Section 2.13 shall be conclusive absent manifest error. The Borrowers shall pay such amount to Agent or the Lender, as applicable, within 30 days of the date of their receipt of such certificate. If a payment of any LIBOR Rate

27

Loan on a day other than the last day of the applicable Interest Period would result in a Funding Loss, Agent may, in its sole discretion at the request of the Borrowers, hold the amount of such payment as cash collateral in support of the Obligations until the last day of such Interest Period and apply such amounts to the payment of the applicable LIBOR Rate Loan on such last day, it being agreed that Agent has no obligation to so defer the application of payments to any LIBOR Rate Loan and that, in the event that Agent does not defer such application, the Borrowers shall be obligated to pay any resulting Funding Losses.

(iii)    Unless Agent, in its sole discretion, agrees otherwise, Borrowers shall have not more than ten (10) LIBOR Rate Loans in effect at any given time. Borrowers may only exercise the LIBOR Option for proposed LIBOR Rate Loans of at least $1,000,000 (and integral multiples of $500,000 in excess thereof).

(c)    Conversion. The Borrowers may convert LIBOR Rate Loans to Base Rate Loans at any time; provided, that in the event that LIBOR Rate Loans are converted or prepaid on any date that is not the last day of the Interest Period applicable thereto, including as a result of any prepayment through the required application by Agent of any payments or proceeds of Collateral in accordance with Section 2.4(b) or for any other reason, including early termination of the term of this Agreement or acceleration of all or any portion of the Obligations pursuant to the terms hereof, each Borrower of such Revolving Loans shall indemnify, defend, and hold Agent and the Lenders and their Participants harmless against any and all Funding Losses in accordance with Section 2.13(b)(ii).

(d)    Special Provisions Applicable to LIBOR Rate.

(i)The LIBOR Rate may be adjusted by Agent with respect to any Lender on a prospective basis to take into account any additional or increased costs to such Lender of maintaining or obtaining any eurodollar deposits or increased costs, in each case, due to changes in applicable law occurring subsequent to the commencement of the then applicable Interest Period, including any Changes in Law (including any Changes in Laws relating to Taxes, other than Indemnified Taxes, which shall be governed by Section 17, and Excluded Taxes) and changes in the reserve requirements imposed by the Board of Governors, which additional or increased costs would increase the cost of funding or maintaining loans bearing interest at the LIBOR Rate. In any such event, the affected Lender shall give Borrowers and Agent notice of such a determination and adjustment and Agent promptly shall transmit the notice to each other Lender and, upon its receipt of the notice from the affected Lender, Borrowers may, by notice to such affected Lender (A) require such Lender to furnish to Borrowers a statement setting forth in reasonable detail the basis for adjusting such LIBOR Rate and the method for determining the amount of such adjustment, or (B) repay the LIBOR Rate Loans of such Lender with respect to which such adjustment is made (together with any amounts due under Section 2.13(b)(ii)).

(ii)    If any Lender determines that any applicable law has made it unlawful for any Lender to make, maintain or fund LIBOR Rate Loans, or to determine or charge interest rates based upon the LIBOR Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the applicable interbank market, then, on notice thereof by such Lender to Parent through Agent, any obligation of such Lender to make or continue LIBOR Rate Loans or to convert Base Rate Loans to LIBOR Rate Loans, shall be suspended until such Lender notifies Agent and Parent that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrowers shall, upon demand from such Lender (with a copy to Agent), prepay or convert all such LIBOR Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such LIBOR Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such LIBOR Rate Loans. Upon any such prepayment or conversion, each Borrower shall also pay accrued interest on the amount of Loans so prepaid or converted.

(iii)    If the Required Lenders determine that for any reason in connection with any request for a LIBOR Rate Loan or a conversion to or continuation thereof that (a) deposits are not

28

being offered to banks in the applicable offshore interbank market for the applicable amount and Interest Period of such LIBOR Rate Loan, (b) adequate and reasonable means do not exist for determining the LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR Rate Loan, or (c) the LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such LIBOR Rate Loan, Agent will promptly so notify Parent and each Lender. Thereafter, the obligation of the Lenders to make or maintain LIBOR Rate Loans shall be suspended until Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, Parent (on behalf of the Borrowers) may revoke any pending request for a Borrowing of, conversion to or continuation of LIBOR Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

(iv)    Notwithstanding anything to the contrary in this Agreement or any other Loan Documents, if Agent determines (which determination shall be conclusive absent manifest error), or Parent or the Required Lenders notify Agent (with, in the case of the Required Lenders, a copy to Parent) that Parent or the Required Lenders (as applicable) have determined, that:

(A)    adequate and reasonable means do not exist for ascertaining the LIBOR Rate for any requested Interest Period hereunder or any other tenors of the LIBOR Rate, including, without limitation, because the LIBOR Screen Rate is not available or published on a current basis and such circumstances are unlikely to be temporary; or

(B)    the administrator of the LIBOR Screen Rate or a Governmental Authority having jurisdiction over Agent or such administrator has made a public statement identifying a specific date after which the LIBOR Rate or the LIBOR Screen Rate shall no longer be made available, or used for determining the interest rate of loans, provided that, at the time of such statement, there is no successor administrator that is satisfactory to the Agent, that will continue to provide the LIBOR Rate after such specific date (such specific date, the “Scheduled Unavailability Date”), or

(C)    the administrator of the LIBOR Screen Rate or a Governmental Authority having jurisdiction over such administrator has made a public statement announcing that all Interest Periods and other tenors of the LIBOR Rate are no longer representative,

(D)    (C) syndicated loans currently being executed, or that include language similar to that contained in this Section, are being executed or amended (as applicable) to incorporate or adopt a new benchmark interest rate to replace the LIBOR Rate,

then, in the case of clauses (A) through (C) above, on a date and time determined by Agent (any such date, "LIBOR Replacement Date"), which date shall be at the end of an Interest Period or on the relevant interest payment date, as applicable, for interest calculated and shall occur reasonably promptly upon the occurrence of any of the events or circumstances under clauses (A), (B) or (C) above and, solely with respect to clause (B) above, no later than the Scheduled Unavailability Date, the LIBOR Rate will be replaced hereunder and under the other Loan Documents with, subject to the proviso below, the first available alternative set forth in the order below for any payment period for interest calculated that can be determined by Agent, in each case, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document ("LIBOR Successor Rate"; and any such rate before giving effect to the Related Adjustment, "Pre-Adjustment Successor Rate"):

(x)Term SOFR plus the Related Adjustment; and

(y) SOFR plusthe Related Adjustment;

andin the case of clause (D) above, Agent and Borrowermay amend this Agreement solelyfor the purpose of replacing the LIBOR Rate under this Agreement and the other Loan Documents in accordance with the definition of "LIBOR Successor Rate" and such amendment will become effective at 5:00 p.m. on the fifth Business Day after Agent shall have notified Lenders and Borrower of the occurrence of the

29

circumstances described in clause (D) above unless, prior to such time, Required Lenders have delivered to Agent written notice that such Required Lenders object to the implementation of a LIBOR Successor Rate pursuant to such clause; provided, that if Agent determines that Term SOFR has become available, is administratively feasible for Agent and would have been identified as the Pre-Adjustment Successor Rate in accordance with the foregoing if it had been so available at the time that the LIBOR Successor Rate then in effect was so identified, and notifies Borrower and Lenders of such availability, then from and after the beginning of the Interest Period, relevant interest payment date or payment period for interest calculated, in each case, commencing no less than 30 days after the date of such notice, the Pre-Adjustment Successor Rate shall be Term SOFR and the LIBOR Successor Rate shall be Term SOFR plusthe relevant Related Adjustment.

Agent will promptly (in one or more notices) notify Borrower and Lenders of (x) any occurrence of any of the events, periods or circumstances under clauses (A) through (D) above, (y) a LIBOR Replacement Date, and (z) the LIBOR Successor Rate. AnyLIBOR Successor Rate shall be applied in a manner consistent with market practice; provided,that to the extent such market practice is not administratively feasible for Agent, such LIBOR Successor Rate shall be applied in a manner as otherwise reasonably determined by Agent. Notwithstanding anything else herein, if at any time any LIBOR Successor Rate as so determined would otherwise be less than 0.25%, the LIBOR Successor Rate will be deemed to be 0.25% for the purposes of this Agreement and the other Loan Documents.

In connection with the implementation of a LIBOR Successor Rate, Agent will have the right to make LIBOR Successor Rate Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such LIBOR Successor Rate Conforming Changes will become effective without any further action or consent of any other party to this Agreement; provided, that with respect to any such amendment effected, Agent shall post each such amendment implementing such LIBOR Successor Rate Conforming Changes to Borrower and Lenders reasonably promptly after such amendment becomes effective.

If events or circumstances of the type described in clauses (A) through (C) above have occurred with respect to the LIBOR Successor Rate then in effect, then the successor rate thereto shall be determined in accordance with the definition of "LIBOR Successor Rate."

then, reasonably promptly afterNotwithstanding anything to the contrary herein, (a) after any such determination by Agent or receipt by Agent of any such notice described under Section 2.13(d)(IV)(A) through (C), as applicable, Agent and Parent may amend this Agreement to replace the LIBOR Rate with (x) one or more SOFR Based Rates or (y) anif Agent determines that none of the LIBOR Successor Rates is available on or prior to the LIBOR Replacement Date, (ii) if the events or circumstances described in Section 2.13(d)(IV)(D) have occurred but none of the LIBOR Successor Rates is available, or (iii) if the events or circumstances of the type described in Section 2.13(d)(IV)(A) through (C) have occurred with respect to the LIBOR Successor Rate then in effect and Agent determines that none of the LIBOR Successor Rates is available, then in each case, Agent and Borrower may amend this Agreement solely for the purpose of replacing LIBOR or any then current LIBOR Successor Rate in accordance with this Section at the end of any Interest Period, relevant interest payment date or payment period for interest calculated, as applicable, with another alternate benchmark rate, giving due consideration to any evolving or then existing convention for similar DollarU.S. dollar denominated syndicated credit facilities for such alternative benchmarks and, in each case, including any Related Adjustments and any other mathematical or other adjustments to such benchmark giving due consideration to any evolving or then existing convention for similar DollarU.S. dollar denominated syndicated credit facilities for such benchmarks, which adjustment or method for calculating such adjustment shall be published on an information service as selected by the Agent from time to time in its reasonable discretion and may be periodically updated (the “Adjustment;” and. For the avoidance of doubt, any such proposed rate, a “and adjustments shall constitute a LIBOR Successor Rate”) and any. Any such amendment shall become effective at 5:00 p.m. (New York time) on the fifth Business Day after Agent shall have posted such proposed amendment to all Lenders and ParentBorrower unless, prior to such time, Lenders comprising the Required Lenders have delivered to Agent written notice that such Required Lenders (A) in the case of an amendment to replace the LIBOR Rate with a rate described in clause (x), object to the Adjustment;

30

or (B) in the case of an amendment to replace the LIBOR Rate with a rate described in clause (y), object to such amendment; provided that for the avoidance of doubt, in the case of clause (A), the Required Lenders shall not be entitled to object to any SOFR-Based Rate contained in any such amendment. Such LIBOR Successor Rate shall be applied in a manner consistent with market practice; provided that to the extent such market practice is not administratively feasible for the Agent, such LIBOR Successor Rate shall be applied in a manner as otherwise reasonably determined by the Agent..

If, at the end of any Interest Period, relevant interest payment date or payment period for interest calculated, no LIBOR Successor Rate hasbeen determined in accordance with Section 2.13(d)(IV) and the circumstances under clause 2.13(d)(IV)(A) or (C) above exist or the Scheduled Unavailability Date has occurred (as applicable), Agent will promptly so notify ParentBorrower and each LenderLenders. Thereafter, (xa) the obligation of the Lenders to make or maintain LIBOR Rate Loans shall be suspended (to the extent of the affected LIBOR Rate Loans or, Interest Periods), interest payment dates or payment periods), and (yb) the LIBOR Rate component shall no longer be utilized in determining the Base Rate, until the LIBOR Successor Rate has been determined in accordance with Section2.13(d)(IV). Upon receipt of such notice, any Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of LIBOR Rate Loans (to the extent of the affected LIBOR Rate Loans or, Interest Periods, interest payment dates or payment periods) or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans (subject to the foregoing clause (yb) of this paragraph) in the amount specified therein).

Notwithstanding anything else herein, any definition of LIBOR Successor Rate shall provide that in no event shall such LIBOR Successor Rate be less than zero for purposes of this Agreement.

In connection with the implementation of a LIBOR Successor Rate, the Agent will have the right to make LIBOR Successor Rate Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such LIBOR Successor Rate Conforming Changes will become effective without any further action or consent of any other party to this Agreement.

(e)    No Requirement of Matched Funding. Anything to the contrary contained herein notwithstanding, neither Agent, nor any Lender, nor any of their Participants, is required actually to acquire eurodollar deposits to fund or otherwise match fund any Obligation as to which interest accrues at the LIBOR Rate.

2.14    Capital Requirements.

(a)    If, after the date hereof, any Issuing Bank or any Lender determines that (1) any Change in Law regarding capital or reserve requirements for banks or bank holding companies, or (2) compliance by such Issuing Bank or such Lender, or their respective parent bank holding companies, with any guideline, request or directive of any Governmental Authority regarding capital adequacy or liquidity requirements (whether or not having the force of law), has the effect of reducing the return on such Issuing Bank’s, such Lender’s, or such holding companies’ capital as a consequence of such Issuing Bank’s or such Lender’s commitments hereunder to a level below that which such Issuing Bank, such Lender, or such holding companies could have achieved but for such Change in Law or compliance (taking into consideration such Issuing Bank’s, such Lender’s, or such holding companies’ then existing policies with respect to capital adequacy or liquidity requirements and assuming the full utilization of such entity’s capital) by any amount deemed by such Issuing Bank or such Lender to be material, then such Issuing Bank or such Lender may notify Borrowers and Agent thereof. Following receipt of such notice, the Borrowers agree to pay such Issuing Bank or such Lender on demand the amount of such reduction or return of capital as and when such reduction is determined, payable within 30 days after presentation by such Issuing Bank or such Lender of a statement in the amount and setting forth in reasonable detail such Issuing Bank’s or such Lender’s calculation thereof and the assumptions upon which such calculation was based (which statement shall be deemed true and correct absent manifest error). In determining such amount, such Issuing Bank or such Lender may use any reasonable averaging and attribution methods. Failure or delay on the part of such Issuing Bank or any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Issuing Bank’s or such

31

Lender’s right to demand such compensation; provided that no Borrower shall be required to compensate an Issuing Bank or a Lender pursuant to this Section for any reductions in return incurred more than 180 days prior to the date that such Issuing Bank or such Lender notifies Borrowers of such Change in Law giving rise to such reductions and of such Lender’s intention to claim compensation therefor; providedfurther that if such claim arises by reason of the Change in Law that is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

(b)    If Issuing Bank or any Lender requests additional or increased costs referred to in Section 2.11(m), or Section 2.13(d)(i) or amounts under Section 2.14(a) or sends a notice under Section 2.13(d)(ii) relative to changed circumstances (such Issuing Bank or Lender, an “Affected Lender”), then such Affected Lender shall use reasonable efforts to promptly designate a different one of its lending offices or to assign its rights and obligations hereunder to another of its offices or branches, if (i) in the reasonable judgment of such Affected Lender, such designation or assignment would eliminate or reduce amounts payable pursuant to Section 2.11(m), Section 2.13(d)(i) or Section 2.14(a), as applicable, or would eliminate the illegality or impracticality of funding or maintaining LIBOR Rate Loans and (ii) in the reasonable judgment of such Affected Lender, such designation or assignment would not subject it to any material unreimbursed cost or expense and would not otherwise be materially disadvantageous to it. Borrowers agree to pay all reasonable out-of-pocket costs and expenses incurred by such Affected Lender in connection with any such designation or assignment. If, after such reasonable efforts, such Affected Lender does not so designate a different one of its lending offices or assign its rights to another of its offices or branches so as to eliminate Borrowers’ obligation to pay any future amounts to such Affected Lender pursuant to Section 2.11(m), Section 2.13(d)(i) or Section 2.14(a), as applicable, or to enable the Borrowers to obtain LIBOR Rate Loans, then Borrowers (without prejudice to any amounts then due to such Affected Lender under Section 2.11(m), Section 2.13(d)(i) or Section 2.14(a), as applicable) may, unless prior to the effective date of any such assignment the Affected Lender withdraws its request for such additional amounts under Section 2.11(m), Section 2.13(d)(i) or Section 2.14(a), as applicable, or indicates that it is no longer unlawful or impractical to fund or maintain LIBOR Rate Loans, may designate a different Issuing Bank or substitute a Lender, in each case, reasonably acceptable to Agent to purchase the Obligations owed to such Affected Lender and such Affected Lender’s commitments hereunder (a “Replacement Lender”), and if such Replacement Lender agrees to such purchase, such Affected Lender shall assign to the Replacement Lender its Obligations and commitments, and upon such purchase by the Replacement Lender, which such Replacement Lender shall be deemed to be “Issuing Bank” or a “Lender” (as the case may be) for purposes of this Agreement and such Affected Lender shall cease to be “Issuing Bank” or a “Lender” (as the case may be) for purposes of this Agreement.

(c)    Notwithstanding anything herein to the contrary, the protection of Sections 2.11(m), 2.13(d), and 2.14 shall be available to each Issuing Bank and each Lender (as applicable) regardless of any possible contention of the invalidity or inapplicability of the law, rule, regulation, judicial ruling, judgment, guideline, treaty or other change or condition which shall have occurred or been imposed, so long as it shall be customary for issuing banks or lenders affected thereby to comply therewith. Notwithstanding any other provision herein, neither any Issuing Bank nor any Lender shall demand compensation pursuant to this Section 2.14 if it shall not at the time be the general policy or practice of such Issuing Bank or such Lender (as the case may be) to demand such compensation in similar circumstances under comparable provisions of other credit agreements, if any.

2.15    Joint and Several Liability.

(a)    Each Borrower is accepting joint and several liability for the Obligations hereunder and under the other Loan Documents in consideration of the financial accommodations to be provided by the Lender Group under this Agreement, for the mutual benefit, directly and indirectly, of each Borrower and, with respect to Letters of Credit, their Subsidiaries, and in consideration of the undertakings of the other Borrowers to accept joint and several liability for the Obligations.

(b)    Each Borrower, jointly and severally, hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with the other Borrowers,

32

with respect to the payment and performance of all of the Obligations (including any Obligations arising under this Section 2.15), it being the intention of the parties hereto that all the Obligations shall be the joint and several obligations of each Borrower without preferences or distinction among them.

(c)    If and to the extent that any Borrower shall fail to make any payment with respect to any of the Obligations as and when due or to perform any of the Obligations in accordance with the terms thereof, then in each such event the other Borrowers will make such payment with respect to, or perform, such Obligation until such time as all of the Obligations are paid in full.

(d)    The Obligations of each Borrower under the provisions of this Section 2.15 constitute the absolute and unconditional, full recourse Obligations of each Borrower enforceable against each Borrower to the full extent of its properties and assets, irrespective of the validity, regularity or enforceability of the provisions of this Agreement (other than this Section 2.15(d)) or any other circumstances whatsoever.

(e)    Except as otherwise expressly provided in this Agreement, each Borrower hereby waives notice of acceptance of its joint and several liability with respect to the other Borrowers, notice of any Revolving Loans or Letters of Credit issued under or pursuant to this Agreement, notice of the occurrence of any Default, Event of Default, or of any demand for any payment under this Agreement, notice of any action at any time taken or omitted by Agent or Lenders under or in respect of any of the Obligations, any requirement of diligence or to mitigate damages and, generally, to the extent permitted by applicable law, all demands, notices and other formalities of every kind in connection with this Agreement (except as otherwise provided in this Agreement). Each Borrower hereby assents to, and waives notice of, any extension or postponement of the time for the payment of any of the Obligations, the acceptance of any payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by Agent or Lenders at any time or times in respect of any default by any Borrower in the performance or satisfaction of any term, covenant, condition or provision of this Agreement, any and all other indulgences whatsoever by Agent or Lenders in respect of any of the Obligations, and the taking, addition, substitution or release, in whole or in part, at any time or times, of any security for any of the Obligations or the addition, substitution or release, in whole or in part, of any Borrower. Without limiting the generality of the foregoing, each Borrower assents to any other action or delay in acting or failure to act on the part of any Agent or Lender with respect to the failure by any Borrower to comply with any of its respective Obligations, including, without limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with applicable laws or regulations thereunder, which might, but for the provisions of this Section 2.15 afford grounds for terminating, discharging or relieving any Borrower, in whole or in part, from any of its Obligations under this Section 2.15, it being the intention of each Borrower that, so long as any of the Obligations hereunder remain unsatisfied, the Obligations of each Borrower under this Section 2.15 shall not be discharged except by performance and then only to the extent of such performance. The Obligations of each Borrower under this Section 2.15 shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect to any other Borrower or any Agent or Lender.

(f)    Each Borrower represents and warrants to Agent and Lenders that such Borrower is currently informed of the financial condition of Borrowers and of all other circumstances which a diligent inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Each Borrower further represents and warrants to Agent and Lenders that such Borrower has read and understands the terms and conditions of the Loan Documents. Each Borrower hereby covenants that such Borrower will continue to keep informed of the Borrowers’ financial condition and of all other circumstances which bear upon the risk of nonpayment or nonperformance of the Obligations.

(g)    The provisions of this Section 2.15 are made for the benefit of Agent, each member of the Lender Group, each Bank Product Provider, and their respective successors and assigns, and may be enforced by it or them from time to time against any or all Borrowers (to the extent provided in this Section 2.15) as often as occasion therefor may arise and without requirement on the part of Agent, any member of the Lender Group, any Bank Product Provider, or any of their successors or assigns first

33

to marshal any of its or their claims or to exercise any of its or their rights against any Borrower or to exhaust any remedies available to it or them against any Borrower or to resort to any other source or means of obtaining payment of any of the Obligations hereunder or to elect any other remedy. The provisions of this Section 2.15 shall remain in effect until all of the Obligations shall have been paid in full or otherwise fully satisfied. If at any time, any payment, or any part thereof, made in respect of any of the Obligations, is rescinded or must otherwise be restored or returned by Agent or any Lender upon the insolvency, bankruptcy or reorganization of any Borrower, or otherwise, the provisions of this Section will forthwith be reinstated in effect, as though such payment had not been made.

(h)    Each Borrower hereby agrees that it will not enforce any of its rights of contribution or subrogation against any other Borrower with respect to any liability incurred by it hereunder or under any of the other Loan Documents, any payments made by it to Agent or Lenders with respect to any of the Obligations or any collateral security therefor until such time as all of the Obligations have been paid in full in cash. Any claim which any Borrower may have against any other Borrower with respect to any payments to any Agent or any member of the Lender Group hereunder or under any of the Bank Product Agreements are hereby expressly made subordinate and junior in right of payment, without limitation as to any increases in the Obligations arising hereunder or thereunder, to the prior payment in full in cash of the Obligations and, in the event of any insolvency, bankruptcy, receivership, liquidation, reorganization or other similar proceeding under the laws of any jurisdiction relating to any Borrower, its debts or its assets, whether voluntary or involuntary, all such Obligations shall be paid in full in cash before any payment or distribution of any character, whether in cash, securities or other property, shall be made to any other Borrower therefor.

(i)    Each Borrower hereby agrees that after the occurrence and during the continuance of any Event of Default, upon notice from the Agent, such Borrower will not demand, sue for or otherwise attempt to collect any indebtedness of any other Borrower owing to such Borrower until the Obligations shall have been paid in full in cash. If, notwithstanding the foregoing sentence, such Borrower shall collect, enforce or receive any amounts in respect of such indebtedness, such amounts shall be collected, enforced and received by such Borrower as trustee for Agent, and such Borrower shall deliver any such amounts to Agent for application to the Obligations in accordance with Section 2.4(b).

2.16    Incremental Borrowings.

(a)    Increases of the Revolver Commitments. The Borrowers may at any time or from time to time after the Closing Date, by notice from the Parent to the Agent (whereupon the Agent shall promptly deliver a copy to each of the Lenders), request one or more incremental Tranche A Revolver Commitments (each an “Upsize Incremental Commitment” and all of them, collectively, the “Upsize Incremental Commitments” and any such loans thereunder, the “Upsize Incremental Loans”). Each tranche of Upsize Incremental Commitments shall be in an aggregate principal amount that is not less than $10,000,000; provided that such amount may be less than $10,000,000 if such amount represents all remaining availability under the limit set forth in the next sentence. Any such increase in Tranche A Revolver Commitments may increase the Letter of Credit Sublimit subject to the consent of the Agent and the applicable Issuing Bank; provided that any such increase in the Letter of Credit Sublimit shall be provided by an Issuing Bank reasonably acceptable to the Agent and the Parent and no Issuing Bank at the time shall have any obligation to provide such increase. Notwithstanding anything to the contrary herein, the aggregate principal amount of the Upsize Incremental Commitments shall not exceed $400,000,000500,000,000 after the Second Amendment Effective Date less the aggregate principal amount of all Foreign Subsidiary Incremental Commitments which have been provided pursuant to Section 2.16(c). The Upsize Incremental Loans (i) shall rank pari passu in right of payment and of security with the Loans and (ii) shall be implemented by way of increase of the Tranche A Revolver Commitments and, except as to arrangement, underwriting or similar fees, shall be on terms identical to the existing Tranche A Revolver Commitments, including the Applicable Margin and any other pricing matter related to the Tranche A Revolver Commitments; provided that the OID or up-front fees (if any) applicable to any Upsize Incremental Loans will be determined by the Borrowers and the Lenders and/or Additional Lenders providing such Upsize Incremental Commitments and Upsize Incremental Loans. As a condition precedent to such an increase, (i) no Default or Event of Default shall exist on the date of the

34

effectiveness of any Incremental Amendment (or would exist after giving effect thereto), (ii) the representations and warranties contained in the Loan Documents shall be accurate in all material respects before and after the effectiveness of any Incremental Amendment referred to below; provided that, to the extent that such representations and warranties specifically refer to an earlier date, they shall be true and correct in all material respects as of such earlier date; provided, further, that, any representation and warranty that is qualified as to “materiality”, “Material Adverse Effect” or similar language shall be true and correct (after giving effect to any qualification therein) in all respects on such respective dates, (iii) all fees and expenses owing in respect of any such Incremental Amendment to the Agent and the Lenders and/or Additional Lenders providing the Upsize Incremental Commitments thereunder shall have been paid and (iv) the Borrowers shall have delivered all customary agreements, certificates, opinions and other customary documents reasonably requested by the Agent. No Lender shall have any obligation, express or implied, to offer to provide any Upsize Incremental Commitments.

(b)    Adjustment of Tranche A Revolving Loans for Increases of the Tranche A Revolver Commitment. Each Tranche A Revolving Lender that is acquiring an Upsize Incremental Commitment on the effective date of any Incremental Amendment shall (i) make a Tranche A Revolving Loan, the proceeds of which will be used to prepay the Tranche A Revolving Loans of the other Tranche A Revolving Lenders immediately prior to such effective date and (ii) automatically and without further act be deemed to have assumed a portion of the other Tranche A Revolving Lenders’ participations hereunder in outstanding Letters of Credit and Swing Loan reimbursement obligations, so that, after giving effect thereto, the Tranche A Revolving Loans and Letter of Credit and Swing Loan reimbursement obligations outstanding are held by the Tranche A Revolving Lenders pro rata based on their Tranche A Revolver Commitments after giving effect to such Incremental Amendment. If there is a new borrowing of Tranche A Revolving Loans on the effective date of any Upsize Incremental Amendment, the Tranche A Revolving Lenders after giving effect to such Incremental Amendment shall make such Tranche A Revolving Loans in accordance with Section 2.1.

(c)    Foreign Subsidiary Incremental Facilities. The Borrowers may at any time or from time to time after the Closing Date, by notice from the Parent to the Agent (whereupon the Agent shall promptly deliver a copy to each of the Lenders), request one or more additional asset-based revolving loan facilities be established hereunder (each a “Foreign Subsidiary Incremental Facility”, the commitments of the lenders thereunder, the “Foreign Subsidiary Incremental Commitment” any such loans thereunder, the “Foreign Subsidiary Incremental Loans”) and/or that any then-existing Foreign Subsidiary Incremental Commitments be increased, in each case, denominated in Dollars or another currency agreed to by the Agent and the Foreign Subsidiary Lenders providing such Foreign Subsidiary Incremental Facility and in a minimum amount of $25,000,000, or in increments of $10,000,000 in excess thereof; provided that, in each case, (i) the aggregate principal amount of Foreign Subsidiary Incremental Commitments established pursuant to this clause (c) shall not exceed $100,000,000 less, to the extent in excess of $300,000,000400,000,000, the aggregate principal amount of Upsize Incremental Commitments made pursuant to Section 2.16(a) greater than $300,000,000400,000,000; (ii) the borrowers of such Foreign Subsidiary Incremental Facilities (the “Foreign Subsidiary Borrowers”) shall be wholly-owned Subsidiaries of Parent that are organized under the laws of Canada, England & Wales, the Netherlands, Germany or such other jurisdiction as agreed to by the Agent and the Lenders providing such Foreign Subsidiary Incremental Loans (or, in each case, any state, province or territory thereof, as applicable) (provided that for the avoidance of doubt, such Foreign Subsidiary Borrower shall not be required to become a Guarantor with respect to any Loan); (iii) the borrowing base established for any such Foreign Subsidiary Incremental Facility (including the definitions and components thereof) will be reasonably acceptable to the Agent; (iv) the Agent and Foreign Subsidiary Lenders providing such Foreign Subsidiary Incremental Facility will have received on or prior to the effectiveness of such Foreign Subsidiary Incremental Facility customary field examinations and appraisals, in form and substance reasonably satisfactory to the Agent and such Foreign Subsidiary Lenders, of the Foreign Subsidiary Borrowers’ assets that will be included in the borrowing base for such Foreign Subsidiary Incremental Facility; (v) the advance rates with respect to the collateral of the Foreign Subsidiary Borrowers (the “Foreign Subsidiary Collateral”) under any such Foreign Subsidiary Incremental Facility shall be no higher than the advance rates applicable to the Tranche A Revolving Loans; (vi) the Foreign Subsidiary Lenders that provide such Foreign Subsidiary Incremental Facility shall benefit from a first-priority perfected

35

security interest in the Foreign Subsidiary Collateral for such Foreign Subsidiary Incremental Facility pursuant to documentation reasonably satisfactory to the Agent; it being agreed that no Lender (other than a Foreign Subsidiary Lender in its capacity as such) will benefit from any security interest in the Foreign Subsidiary Collateral; (vii) any such Foreign Subsidiary Incremental Facility (x) may benefit from a guaranty from the Borrowers and the Guarantors which guaranty may be secured by the Collateral on a junior basis to the Liens securing the Obligations of the Lender Group (other than any Foreign Subsidiary Lender) or (y) to the extent requested by the Borrowers or the Agent, such Foreign Subsidiary Incremental Facility may benefit from a guaranty from the Borrower and the Guarantors which guaranty may be secured by the Collateral on a pari passu basis with the Liens securing the Obligations of the Lender Group and, in the event such Foreign Subsidiary Incremental Facility is secured on a pari passu basis with the Liens securing the Obligations of the Lender Group, (A) each Lender (including each Foreign Subsidiary Lender) shall enter into a customary loss sharing agreement in form and substance reasonably acceptable to the Agent and the Supermajority Lenders or (B) the post-enforcement “waterfall” under Section 2.4(b)(iv) shall be amended such that the proceeds of the Collateral of the Loan Parties organized in the United States (or any state or territory thereof) are applied to the Foreign Subsidiary Borrower’s Obligations only after the other Obligations have been paid in full; (viii) the maturity date of any such Foreign Subsidiary Incremental Facility will be the Maturity Date; (ix) each Foreign Subsidiary Borrower shall have appointed a process agent that is a Person incorporated or organized under the laws of the United States of America, any state thereof or in the District of Columbia; (x) no Default or Event of Default shall have occurred and be continuing or shall occur as a result of such establishment or increase in Foreign Subsidiary Incremental Facilities, as applicable; (xi) the representations and warranties contained in the Loan Documents shall be accurate in all material respects (or in all respects with respect to any representation and warranty that is qualified as to “materiality”, “Material Adverse Effect” or similar language) before and after such establishment or increase in Foreign Subsidiary Incremental Facilities, as applicable; (xii) prior to the date of such establishment or increase, each Lender shall have received written notice from Agent of the aggregate principal amount of such requested Foreign Subsidiary Incremental Facility or increase thereto, as applicable; (xiii) notwithstanding anything to the contrary in this Agreement or any of the other Loan Documents, (a) the Obligations of the Foreign Subsidiary Borrowers under this Agreement or any of the other Loan Documents shall be separate and distinct from the Obligations of any Loan Party organized in the United States including, without limitation, the Parent, and shall be expressly limited to the Obligations of each applicable Foreign Subsidiary Borrower, (b) the liability of any Foreign Subsidiary Borrower for the payment and performance of its covenants, representations and warranties or obligations (payment or otherwise) set forth in this Agreement and the other Loan Documents shall be several from but not joint with the Obligations of the Parent and any other Loan Party organized in the United States, and (c) the Foreign Subsidiary Collateral, or any other credit support provided by the Foreign Subsidiary Borrowers, shall not secure or be applied in satisfaction, by way of payment, prepayment, or otherwise, of all or any portion of the Obligations of the Parent and any other Loan Party organized in the United States; and (xiv) the Borrowers shall, and shall cause their applicable Subsidiaries (including any applicable Foreign Subsidiary Borrowers) to, execute and deliver such documents, opinions, certificates, instruments or information (including any “know your customer” information and any Beneficial Ownership Regulation information reasonably requested by the Agent or any Lender (through the Agent)) and take such other actions as may be reasonably requested by Agent in connection with such establishment or increase, as applicable. Any request under this Section 2.16(c) shall be submitted by the Borrowers to Agent (and Agent shall forward copies to the Lenders), specify the proposed effective date and the amount of each such requested Foreign Subsidiary Incremental Facility or increase thereto, as applicable, and be accompanied by an officer’s certificate of the Borrowers stating that (x) no Default or Event of Default exists or will occur as a result of such establishment or increase(s), as applicable and (y) the representations and warranties contained in the Loan Documents are accurate in all material respects (or in all respects with respect to any representation and warranty that is qualified as to “materiality”, “Material Adverse Effect” or similar language) before and after the such establishment or increase(s), as applicable. The Borrowers may also specify any fees offered to those Lenders and/or Additional Lenders (the “Foreign Subsidiary Lenders”) that agree to provide such Foreign Subsidiary Incremental Facilities or increases thereto, as applicable, which fees may be variable based upon the amount by which any such Foreign Subsidiary Lender is willing to increase the principal amount of its Foreign Subsidiary Incremental Commitments and/or provide a new Foreign Subsidiary Incremental Facility, as applicable. No Lender shall have any obligation, express or implied, to offer to provide any

36

Foreign Subsidiary Incremental Facility or to increase its existing Foreign Subsidiary Incremental Commitments.

(d)    Incremental Amendments. Each notice from the Parent pursuant to Section 2.16(a) or (c) shall set forth the requested amount and proposed terms of the relevant Incremental Commitments and Incremental Loans. Incremental Commitments and Incremental Loans may be made by any existing Lender (it being understood that no existing Lender will have an obligation to make a portion of any Incremental Commitment or Incremental Loan) or by any Additional Lender that is an Eligible Transferee reasonably acceptable to the Agent and, in the case of any Upsize Incremental Commitments, each Issuing Bank (each such consent not to be unreasonably withheld, delayed or conditioned). Incremental Commitments shall become effective under this Agreement pursuant to an amendment (an “Incremental Amendment”) to this Agreement and, as appropriate, the other Loan Documents, executed by the Borrowers, each Lender agreeing to provide such Incremental Commitment, if any, each Additional Lender, if any, the Agent and, if applicable, the Issuing Bank. The Incremental Amendment may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the Agent and the Parent, to effect the provisions of this Section 2.16. The effectiveness of (and, in the case of any Incremental Amendment for an Incremental Loan, the Borrowing under) any Incremental Amendment shall be subject to the satisfaction on the date thereof of each of the conditions set forth in Section 3.3. The Borrowers shall use the proceeds of the Incremental Loans for any purpose not prohibited by this Agreement.

This Section 2.16 shall supersede any provisions in Section 14.1 to the contrary.

2.17    Tranche B Exchange Offer.

(a)    Notwithstanding anything to the contrary in this Agreement, subject to the terms of this Section 2.17, the Borrowers may at any time and from time to time (but no more than twice during the term of this Agreement) when no Default or Event of Default then exists or would result immediately after giving effect thereto request that Revolver Commitments, together with any related outstandings, be converted into a Tranche B Facility in an aggregate amount to be agreed between the Borrowers and the Agent not to exceed $150,000,000225,000,000 during the term of this Agreement (a “Tranche B Exchange”). In order to establish any Tranche B Facility, the Borrowers shall provide a notice to the Agent (who shall provide a copy of such notice to each of the Lenders) (a “Tranche B Exchange Offer”) setting forth the proposed terms of the Tranche B Revolver Commitments to be established, which shall (x) be identical as offered to each Lender (including as to fees payable, if any) and (y) be on the terms set forth herein relating to the Tranche B Facility and such other terms as may be agreed by Agent and the Borrowers.

(b)    The Borrowers shall provide the Tranche B Exchange Offer at least ten (10) Business Days prior to the date on which Lenders are requested to respond, and shall agree to such procedures, if any, as may be established by, or acceptable to, the Agent, in each case acting reasonably to accomplish the purposes of this Section 2.17. No Lender shall have any obligation to agree to participate in any Tranche B Exchange Offer. Any Lender wishing to participate in the Tranche B Exchange Offer shall notify the Agent on or prior to the date specified in such Tranche B Exchange Offer of the amount of its existing Tranche A Revolver Commitments which it requests be converted into Tranche B Revolver Commitments. Any Lender that does not respond to the Tranche B Exchange Offer on or prior to the date specified therein shall be deemed to have rejected such Tranche B Exchange Offer. In the event that the aggregate principal amount of existing Tranche A Revolver Commitments of Lenders accepting such Tranche B Exchange Offer exceeds the amount of Tranche B Revolver Commitments requested, existing Tranche A Revolver Commitments shall be converted to Tranche B Revolver Commitments on a pro rata basis based on the aggregate principal amount of Tranche A Revolving Loans included in each such Tranche B Exchange Offer.

(c)    Tranche B Revolver Commitments shall be established pursuant to an amendment to this Agreement among the Borrowers, Agent and each Tranche B Revolving Lender

37

providing Tranche B Revolver Commitments thereunder which shall be consistent with the provisions set forth in Section 2.17(a) above (but which shall not require the consent of any other Lender). Such amendment shall include such changes as the Agent and the Borrowers shall deem necessary or desirable to clarify the administration of the Tranche B Facility and the Tranche B Borrowing Base hereunder in a manner consistent with this Agreement, including to amend the definition of Line Cap herein to include the aggregate amount of the Tranche A Borrowing Base and the Tranche B Borrowing Base, to amend the definition of Excess Availability herein to include the Tranche B Borrowing Base in the calculation of Excess Availability, to calculate an aggregate Borrowing Base where appropriate and any related changes. The Agent shall promptly notify each Lender as to the effectiveness of such amendment. Upon the effectiveness of such amendment, the establishment of any Tranche B Revolver Commitments shall result in a permanent Dollar-for-Dollar decrease in the Tranche A Revolver Commitments. If amounts are outstanding under the Tranche A Facility at the time of establishment of a Tranche B Facility, such amounts up to the Tranche B Line Cap shall be deemed outstanding under the newly-established Tranche B Facility, and only the excess over the applicable Tranche B Line Cap shall be deemed thereafter outstanding under the Tranche A Facility. The Lenders under the Tranche A Facility and Tranche B Facility will be required to make such payments and reallocations to one another as the Agent shall see fit in order to effect this reallocation, as a condition to the effectiveness of any amendment instituting a Tranche B Facility.

(d)    With respect to any Tranche B Exchange consummated by the Borrowers pursuant to this Section 2.17, such exchange shall not constitute voluntary or mandatory payments or prepayments for purposes of this Agreement or an incremental borrowing. The Agent and the Lenders hereby consent to each such exchange and the other transactions contemplated by this Section 2.17 and hereby waive the requirements of any provision of this Agreement or any other Loan Document that may otherwise prohibit any transaction contemplated by this Section 2.17; provided that such consent shall not be deemed to be an acceptance of the Tranche B Exchange Offer. Notwithstanding anything to the contrary in this Agreement, no Tranche B Exchange shall be consummated if a Default or Event of Default exists or would result immediately after giving effect thereto.

This Section 2.17 shall supersede any provisions in Section 14.1 (other than clauses (a)(xi) and (c) thereof) to the contrary.

2.18    Tranche A Exchange Offer.

(a)    Notwithstanding anything to the contrary in this Agreement, subject to the terms of this Section 2.18, the Borrowers may at any time and from time to time (but no more than twice during the term of this Agreement) when no Default or Event of Default then exists request or would result immediately after giving effect thereto that up to the full amount of the Tranche B Revolver Commitments, together with any related outstandings, be converted into Tranche A Revolver Commitments (a “Tranche A Exchange”); provided that after giving effect to any such Tranche A Exchange, the aggregate amount of the Tranche A Revolver Usage then outstanding would not exceed the Tranche A Line Cap. In order to effect the Tranche A Exchange, the Borrowers shall provide a notice to the Agent (who shall provide a copy of such notice to each of the Lenders) (a “Tranche A Exchange Offer”).

(b)    The Borrowers shall provide the Tranche A Exchange Offer at least ten (10) Business Days prior to the date on which Lenders are requested to respond, and shall agree to such procedures, if any, as may be established by, or acceptable to, the Agent, in each case acting reasonably to accomplish the purposes of this Section 2.18. No Lender shall have any obligation to agree to participate in any Tranche A Exchange Offer. Any Lender wishing to participate in the Tranche A Exchange Offer shall notify the Agent on or prior to the date specified in such Tranche A Exchange Offer of the amount of its existing Tranche B Revolver Commitments which it requests be converted into Tranche A Revolver Commitments. Any Lender that does not respond to the Tranche A Exchange Offer on or prior to the date specified therein shall be deemed to have rejected such Tranche A Exchange Offer. In the event that the aggregate principal amount of existing Tranche B Revolver Commitments of Lenders accepting such Tranche A Exchange Offer exceeds the amount of Tranche A Revolver Commitments requested, existing Tranche B Revolver Commitments shall be converted to Tranche A Revolver

38

Commitments on a pro rata basis based on the aggregate principal amount of Tranche B Revolving Loans included in each such Tranche A Exchange Offer.

(c)    Any such Tranche A Exchange shall be established pursuant to an amendment to this Agreement among the Borrowers, Agent and each Tranche B Revolving Lender participating in the Tranche A Exchange which shall be consistent with the provisions set forth in Section 2.18(a) above (but which shall not require the consent of any other Lender). Such amendment shall include such changes as the Agent and the Borrowers shall deem necessary or desirable to clarify the administration of the Tranche A Facility or the Tranche B Facility and the Tranche A Borrowing Base or the Tranche B Borrowing Base hereunder in a manner consistent with this Agreement. The Agent shall promptly notify each Lender as to the effectiveness of such amendment. Upon the effectiveness of such amendment, the Tranche A Exchange shall result in a permanent Dollar-for-Dollar decrease in the Tranche B Revolver Commitments. If amounts are outstanding under the Tranche B Facility at the time of the Tranche A Exchange, such amounts up to the applicable Tranche A Line Cap shall be deemed outstanding under the Tranche A Facility. The Lenders under the Tranche A Facility and Tranche B Facility will be required to make such payments and reallocations to one another as the Agent shall see fit in order to effect this reallocation, as a condition to the effectiveness of any amendment instituting the Tranche A Exchange.

(d)    With respect to any Tranche A Exchange consummated by the Borrowers pursuant to this Section 2.18, such exchange shall not constitute voluntary or mandatory payments or prepayments or an incremental borrowing for purposes of this Agreement. The Agent and the Lenders hereby consent to each such exchange and the other transactions contemplated by this Section 2.18 and hereby waive the requirements of any provision of this Agreement or any other Loan Document that may otherwise prohibit any transaction contemplated by this Section 2.18; provided that such consent shall not be deemed to be an acceptance of the Tranche A Exchange Offer. Notwithstanding anything to the contrary in this Agreement, no Tranche A Exchange shall be consummated if a Default or Event of Default exists or would result after giving effect thereto.

This Section 2.18 shall supersede any provisions in Section 14.1 (other than clauses (a)(xi) and (c) thereof) to the contrary.

3.     CONDITIONS; TERM OF AGREEMENT.

3.1    Conditions Precedent to the Closing Date.

(b)    declare the Revolver Commitments terminated, whereupon the Revolver Commitments shall immediately be terminated together with (i) any obligation of any Revolving Lender to make Revolving Loans, (ii) the obligation of the Swing Lender to make Swing Loans, and (iii) the obligation of any Issuing Bank to issue Letters of Credit; and

(c)    exercise all other rights and remedies available to Agent or the Lenders under the Loan Documents, under applicable law, or in equity.

The foregoing to the contrary notwithstanding, no Borrower shall have any obligation to any Indemnified Person under this Section 10.3 with respect to any Indemnified Liability that a court of competent jurisdiction finally determines to have resulted from the bad faith, gross negligence or willful misconduct by such Indemnified Person or its officers, directors, employees, attorneys, or agents. This provision shall survive the termination of this Agreement and the repayment in full of the Obligations. If any Indemnified Person makes any payment to any other Indemnified Person with respect to an Indemnified Liability as to which Borrowers were required to indemnify the Indemnified Person receiving such payment, the Indemnified Person making such payment is entitled to be indemnified and reimbursed by Borrowers with

58

respect thereto. This Section 10.3 shall not apply to (x) any Taxes or any costs attributable to Taxes that are governed by Section 17, or (y) any Excluded Taxes or any costs attributable to Excluded Taxes. WITHOUT LIMITATION, THE FOREGOING INDEMNITY SHALL APPLY TO EACH INDEMNIFIED PERSON WITH RESPECT TO INDEMNIFIED LIABILITIES WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF ANY NEGLIGENT ACT OR OMISSION (OTHER THAN A GROSSLY NEGLIGENT ACT OR OMISSION OR TO THE EXTENT CONSTITUTING BAD FAITH OR WILLFUL MISCONDUCT) OF SUCH INDEMNIFIED PERSON OR OF ANY OTHER PERSON.

(d)Immediately upon Agent’s receipt of the required processing fee, if applicable, and delivery of notice to the assigning Lender pursuant to Section 13.1(b), this Agreement shall be deemed to be amended to the extent, but only to the extent, necessary to reflect the addition of the Assignee and the resulting adjustment of the Revolver Commitments arising therefrom.

63

greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. No Participant shall have the right to participate directly in the making of decisions by the Lenders among themselves.

(f)In connection with any such assignment or participation or proposed assignment or participation or any grant of a security interest in, or pledge of, its rights under and interest in this Agreement, a Lender may, subject to the provisions of Section 18.9, disclose all documents and information which it now or hereafter may have relating to any Borrower and its Subsidiaries and their respective businesses.

(g)Any other provision in this Agreement notwithstanding, any Lender may at any time create a security interest in, or pledge, all or any portion of its rights under and interest in this Agreement in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Bank or U.S. Treasury Regulation 31 CFR §203.24 or any other central bank, and such Federal Reserve Bank or such central bank, as applicable, may enforce such pledge or security interest in any manner permitted under applicable law.

(h)Agent (as a non-fiduciary agent on behalf of Borrowers) shall maintain, or cause to be maintained, a register (the “Register”) on which it enters the name and address of each Lender as the registered owner of the Loans (and the principal amount thereof and stated interest thereon) held by such Lender (each, a “Registered Loan”). A Registered Loan (and the registered note, if any, evidencing the same) may be assigned or sold in whole or in part only by registration of such assignment or sale on the Register (and each registered note shall expressly so provide) and any assignment or sale of all or part of such Registered Loan (and the registered note, if any, evidencing the same) may be effected only by registration of such assignment or sale on the Register, together with the surrender of the registered note, if any, evidencing the same duly endorsed by (or accompanied by a written instrument of assignment or sale duly executed by) the holder of such registered note, whereupon, at the request of the designated assignee(s) or transferee(s), one or more new registered notes in the same aggregate principal amount shall be issued to the designated assignee(s) or transferee(s). Prior to the registration of assignment or sale of any Registered Loan (and the registered note, if any evidencing the same), Borrowers, the Agent and the Lenders shall treat the Person in whose name such Registered Loan (and the registered note, if any, evidencing the same) is registered as the owner thereof for the purpose of receiving all payments thereon and for all other purposes, notwithstanding notice to the contrary.

(i)In the event that a Lender sells participations in the Registered Loan, such Lender, as a non-fiduciary agent on behalf of Borrowers, shall maintain (or cause to be maintained) a register on which it enters the name and address of all participants in the Registered Loans held by it (and the principal amount (and stated interest thereon) of the portion of such Registered Loans that is subject to such participations) (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans or participations in Letters of Credit and Swing Loans or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loan or participation in a Letter of Credit or Swing Loan is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. A Registered Loan (and the registered note, if any, evidencing the same) may be participated in whole or in part only by registration of such participation on the Participant Register (and each registered note shall expressly so provide). Any participation of such Registered Loan (and the registered note, if any, evidencing the same) may be effected only by the registration of such participation on the Participant Register. The conclusiveness of the Participant Register shall be subject to the qualification “absent manifest error”.

(j)Agent shall make a copy of the Register (and each Lender shall make a copy of its Participant Register to the extent it has one) available for review by Borrowers from time to time as Borrowers may reasonably request.

64

A Lender may assign this Agreement and the other Loan Documents and its rights and duties hereunder and thereunder pursuant to Section 13.1 and, except as expressly required pursuant to Section 13.1, no consent or approval by any Borrower is required in connection with any such assignment.

15.    AGENT.

15.1    Appointment, Authority and Duties of Agent.

(a)Appointment and Authority. Each Lender appoints and designates Bank of America as Agent under all Loan Documents. Agent may, and each Lender authorizes Agent to, enter into all Loan Documents to which Agent is intended to be a party and accept the Guaranty and Security Agreement. Any action taken by Agent in accordance with the provisions of the Loan Documents, and the exercise by Agent of any rights or remedies set forth therein, together with all other powers reasonably incidental thereto, shall be authorized by and binding upon all Lenders (an Bank Product Providers). Without limiting the generality of the foregoing, Agent shall have the sole and exclusive authority to (a) act as the disbursing and collecting agent for Lenders with respect to all payments and collections arising in connection with the Loan Documents; (b) execute and deliver as Agent each Loan Document, including any intercreditor or subordination agreement, and accept delivery of each Loan Document; (c) act as collateral agent for the Lenders for purposes of perfecting and administering Liens under the Loan Documents, and for all other purposes stated therein; (d) manage, supervise or otherwise deal with Collateral; and (e) take any Enforcement Action or otherwise exercise any rights or remedies with respect to any Collateral or under any Loan Documents, applicable law or otherwise. Agent alone shall be authorized to determine eligibility and applicable advance rates under the Borrowing Base, whether to impose or release any reserve, or whether any conditions to funding or issuance of a Letter of Credit have been satisfied, which determinations and judgments, if exercised in good faith, shall exonerate Agent from liability to any Lender, Bank Product Provider or other Person for any error in judgment.

(b)Duties. The title of “Agent” is used solely as a matter of market custom and the duties of Agent are administrative in nature only. The Agent shall not have any duties except those expressly set forth in the Loan Documents, and in no event does Agent have any agency, fiduciary or implied duty to or relationship with any Lender, Bank Product Provider or other Person by reason of any Loan Document or related transaction. The conferral upon Agent of any right shall not imply a duty to exercise such right, unless instructed to do so by Lenders in accordance with this Agreement.

(c)Agent Professionals. The Agent may perform its duties through agents and employees. The Agent may consult with and employ Agent Professionals, and shall be entitled to act upon, and shall be fully protected in any action taken in good faith reliance upon, any advice given by an Agent Professional. The Agent shall not be responsible for the negligence or misconduct of any agents, employees or Agent Professionals selected by it with reasonable care.

(d)Instructions of Required Lenders. The rights and remedies conferred upon Agent under the Loan Documents may be exercised without the necessity of joining any other party, unless required by applicable law. In determining compliance with a condition for any action hereunder, including satisfaction of any condition in Section 3, Agent may presume that the condition is satisfactory to a Lender and Bank Product Provider unless Agent has received written notice to the contrary from such Lender or Bank Product Provider before Agent takes the action. Agent may request instructions from Required Lenders or other Lenders or Bank Product Providers with respect to any act (including the failure to act) in connection with any Loan Documents or Collateral, and may seek assurances to its reasonable satisfaction from Lenders or Bank Product Providers of their indemnification obligations against Applicable Claims that could be incurred by Agent. Agent may refrain from any act until it has received such instructions or assurances, and shall not incur liability to any Person by reason of so

68

refraining. Instructions of Required Lenders shall be binding upon all Lenders (and Bank Product Providers), and no Lender (or Bank Product Provider) shall have any right of action whatsoever against Agent as a result of Agent acting or refraining from acting pursuant to instructions of Required Lenders. Notwithstanding the foregoing, instructions by and consent of specific parties shall be required to the extent provided in Section 14.1. In no event shall Agent be required to take any action that it determines in its discretion is contrary to applicable law or any Loan Documents or could subject any Agent-Related Person to liability.

15.2    Liability of Agent. The Agent shall not be liable to any Lender or Bank Product Provider for any action taken or omitted to be taken under the Loan Documents, except for losses directly and solely caused by its bad faith, gross negligence or willful misconduct.The Agent shall not assume any responsibility for any failure or delay in performance or any breach by any Loan Party, Lender or Bank Product Provider of any obligations under the Loan Documents.The Agent shall not make any express or implied representation, warranty or guarantee to Lenders or Bank Product Providers with respect to any Obligations, Collateral, Liens, Loan Documents or Loan Party.No Agent-Related Person shall be responsible to Lender (and Bank Product Providers) for any recitals, statements, information, representations or warranties contained in any Loan Documents or Borrower Materials; the execution, validity, genuineness, effectiveness or enforceability of any Loan Documents; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any Collateral, or the validity, extent, perfection or priority of any Lien therein; the validity, enforceability or collectability of any Obligations; or the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any Loan Party or Account Debtor.No Agent-Related Person shall have any obligation to any Lender or Bank Product Provider to ascertain or inquire into the existence of any Default or Event of Default, the observance by any Loan Party of any terms of the Loan Documents, or the satisfaction of any conditions precedent contained in any Loan Documents.

15.3    Reliance by Agent. The Agent shall be entitled to rely, and shall be fully protected in relying, upon any certification, notice or other communication (including those by telephone, telex, telegram, telecopy or e-mail) believed by it to be genuine and correct and to have been signed, sent or made by the proper Person.The Agent shall have a reasonable and practicable amount of time to act upon any instruction, notice or other communication under any Loan Document, and shall not be liable for any delay in acting.

15.4    Notice of Default or Event of Default. Agent shall not be deemed to have knowledge of any Default or Event of Default, or of any failure to satisfy any conditions in Section 3, unless it has received written notice from a Borrower or Required Lenders specifying the occurrence and nature thereof. If any Lender acquires knowledge of a Default, Event of Default or failure of such conditions, it shall promptly notify Agent and the other Lenders thereof in writing. Each Lender (and Bank Product Provider) agrees that, except as otherwise provided in any Loan Documents or with the written consent of Agent and Required Lenders, it will not take any Enforcement Action, accelerate Obligations (other than Bank Product Obligations) or assert any rights relating to any Collateral.

15.5    Due Diligence and Non-Reliance. Each Lender acknowledges and agrees that it has, independently and without reliance upon Agent or any other Lenders, and based upon such documents, information and analyses as it has deemed appropriate, made its own credit analysis of each Loan Party and its own decision to enter into this Agreement and to fund Loans and participate in Letters of Credit hereunder. Each Lender (and Bank Product Provider) has made such inquiries as it feels necessary concerning the Loan Documents, Collateral and Loan Parties. Each Lender (and Bank Product Provider) acknowledges and agrees that the other Lenders (and Bank Product Providers) have made no representations or warranties concerning any Loan Party, any Collateral or the legality, validity, sufficiency or enforceability of any Loan Documents or Obligations. Each Lender (and Bank Product Provider) will, independently and without reliance upon any other Lender (or Bank Product Provider), and based upon such financial statements, documents and information as it deems appropriate at the time, continue to

69

make and rely upon its own credit decisions in making Loans and participating in Letters of Credit, and in taking or refraining from any action under any Loan Documents. Except for notices, reports and other information expressly requested by a Lender, Agent shall have no duty or responsibility to provide any Lender (or Bank Product Provider) with any notices, reports or certificates furnished to Agent by any Loan Party or any credit or other information concerning the affairs, financial condition, business or properties of any Loan Party (or any of its Affiliates) which may come into possession of any Agent-Related Person.

15.6    Indemnification. EACH LENDER (AND BANK PRODUCT PROVIDER) SEVERALLY SHALL INDEMNIFY AND HOLD HARMLESS AGENT-RELATED PERSONS AND ISSUING BANK INDEMNITEES, TO THE EXTENT NOT REIMBURSED BY LOAN PARTIES (AND WITHOUT LIMITING THEIR OBLIGATION TO DO SO), ON A PRO RATA BASIS, AGAINST ALL APPLICABLE CLAIMS THAT MAY BE INCURRED BY OR ASSERTED AGAINST ANY SUCH INDEMNIFIED PERSON, PROVIDED THAT ANY APPLICABLE CLAIM AGAINST AN AGENT-RELATED PERSON RELATES TO OR ARISES FROM ITS ACTING AS OR FOR AGENT (IN THE CAPACITY OF AGENT); PROVIDED THAT NO LENDER SHALL BE REQUIRED TO INDEMNIFY ANY AGENT-RELATED PERSON OR ISSUING BANK INDEMNITEE FOR APPLICABLE CLAIMS THAT A COURT OF COMPETENT JURISDICTION HAS FINALLY DETERMINED TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH AGENT-RELATED PERSON OR ISSUING BANK INDEMNITEE. In Agent’s discretion, it may reserve for any Applicable Claims made against an Agent-Related Person or Issuing Bank Indemnitee, and may satisfy any judgment, order or settlement relating thereto, from proceeds of Collateral prior to making any distribution of Collateral proceeds to Lenders (and Bank Product Providers). If Agent is sued by any receiver, trustee or other Person for any alleged preference or fraudulent transfer, then any monies paid by Agent in settlement or satisfaction of such proceeding, together with all interest, costs and expenses (including attorneys’ fees) incurred in the defense of same, shall be promptly reimbursed to Agent by each Lender (and Bank Product Provider) to the extent of its Pro Rata Share.

15.7    Individual Capacities. As a Lender, Bank of America shall have the same rights and remedies under the Loan Documents as any other Lender, and the terms “Lenders”, “Required Lenders”, “Supermajority Lenders” or any similar term shall include Bank of America in its capacity as a Lender. Agent, Lenders and their Affiliates may accept deposits from, lend money to, provide Bank Products to, act as financial or other advisor to, and generally engage in any kind of business with, Loan Parties and their Affiliates, as if they were not Agent or Lenders hereunder, without any duty to account therefor to any Lender (or Bank Product Provider). In their individual capacities, Agent, Lenders and their Affiliates may receive information regarding Loan Parties, their Affiliates and their Account Debtors (including information subject to confidentiality obligations), and shall have no obligation to provide such information to any Lender (or Bank Product Provider).

15.8    Successor Agent.

(a)Resignation; Successor Agent. Agent may resign at any time by giving at least 30 days written notice thereof to Lenders and Borrowers. Required Lenders may appoint a successor to replace the resigning Agent, which successor shall be (a) a Lender or an Affiliate of a Lender; or (b) a financial institution reasonably acceptable to Required Lenders and, in either case, provided no Event of Default exists, reasonably acceptable to Borrowers. If no successor agent is appointed prior to the effective date of Agent’s resignation, then Agent may appoint a successor agent that is a financial institution acceptable to it (which shall be a Lender unless no Lender accepts the role) or in the absence of such appointment, Required Lenders shall on such date assume all rights and duties of Agent hereunder, provided that Agent shall consult with Parent prior to such appointment. Upon acceptance by any successor Agent of its appointment hereunder, such successor Agent shall thereupon succeed to and become vested with all the powers and duties of the retiring Agent without further act. On the effective date of its resignation, the retiring Agent shall be discharged from its duties and obligations hereunder in its capacity as Agent but shall continue to have all rights and protections under the Loan Documents with respect to actions taken or omitted to be taken by it while Agent, including the indemnification set forth in Sections 15.6 and 10.3, and all rights and protections under this Section 15. Any successor to Bank of

70

America by merger or acquisition of stock or this loan shall continue to be Agent hereunder without further act on the part of any Lender (or Bank Product Provider) or Loan Party.

(b)Co-Collateral Agent. If appropriate under applicable law, Agent may appoint a Person to serve as a co-collateral agent or separate collateral agent under any Loan Document. Each right, remedy and protection intended to be available to Agent under the Loan Documents shall also be vested in such agent. Lenders (and Bank Product Providers) shall execute and deliver any instrument or agreement that Agent may request to effect such appointment. If any such agent shall die, dissolve, become incapable of acting, resign or be removed, then all the rights and remedies of the agent, to the extent permitted by applicable law, shall vest in and be exercised by Agent until appointment of a new agent.

15.9    Agreements Regarding Collateral and Borrower Materials.

(a)Lien Releases; Care of Collateral. Lenders (and Bank Product Providers) authorize Agent to release any Lien with respect to any Collateral (a) upon payment in full of the Obligations (other than unasserted contingent obligations); (b) that is the subject of a disposition or Lien that Borrowers certify in writing is a Permitted Disposition or any other disposition permitted by the Loan Documents or a Permitted Lien entitled to priority over Agent’s Liens (and Agent may rely conclusively on any such certificate without further inquiry); (c) that does not constitute a material part of the Collateral; (d) that is owned by a Loan Party if such Loan Party becomes an Excluded Subsidiary; (e) if required or permitted under the terms of any other Loan Documents, including any intercreditor agreement, or (f) subject to Section 14.1, with the consent of Required Lenders. Lenders (and Bank Product Providers) authorize Agent to subordinate its Liens to any Permitted Purchase Money Indebtedness or other Lien entitled to priority hereunder. The Agent shall not have any obligation to assure that any Collateral exists or is owned by a Loan Party, or is cared for, protected or insured, nor to assure that Agent’s Liens have been properly created, perfected or enforced, or are entitled to any particular priority, nor to exercise any duty of care with respect to any Collateral.

(b)Possession of Collateral. Agent, Lenders and Bank Product Providers appoint each Lender as agent (for the benefit of Lender (and Bank Product Providers)) for the purpose of perfecting Liens in any Collateral held or controlled by such Lender, to the extent such Liens are perfected by possession or control. If any Lender obtains possession or control of any Collateral, it shall notify Agent thereof and, promptly upon Agent’s request, deliver such Collateral to Agent or otherwise deal with it in accordance with Agent's instructions.

(c)Agent shall promptly provide to Lenders, when complete, any field examination, audit, appraisal report or valuation prepared for Agent with respect to any Loan Party or Collateral (“Report”) and other Borrower Materials received pursuant to Schedule 5.1 or 5.2. Reports and other Borrower Materials may be made available to Lenders by providing access to them on the Platform, but Agent shall not be responsible for system failures or access issues that may occur from time to time. Each Lender agrees (a) that Reports are not intended to be comprehensive audits or examinations, and that Agent or any other Person performing an audit or examination will inspect only limited information and will rely significantly upon Borrowers’ books, records and representations; (b) that Agent makes no representation or warranty as to the accuracy or completeness of any Borrower Materials and shall not be liable for any information contained in or omitted from any Borrower Materials, including any Report; and (c) to keep all Borrower Materials confidential in accordance with Section 18.9(a). Each Lender shall indemnify and hold harmless Agent and any other Person preparing a Report from any action such Lender may take as a result of or any conclusion it may draw from any Borrower Materials, as well as from any Applicable Claims arising as a direct or indirect result of Agent furnishing same to such Lender, via the Platform or otherwise.

15.10    Ratable Sharing.

71

(a)If any Lender obtains any payment or reduction of any Obligation, whether through set-off or otherwise, in excess of its ratable share of such Obligation, such Lender shall forthwith purchase from Lenders (and Bank Product Providers) participations in the affected Obligation as are necessary to share the excess payment or reduction on a pro rata basis or in accordance with Section 2.4(b)(iv). If any of such payment or reduction is thereafter recovered from the purchasing Lender, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest. Notwithstanding the foregoing, if a Defaulting Lender obtains a payment or reduction of any Obligation, it shall immediately turn over the full amount thereof to Agent for application under Section 2.3(i) and it shall provide a written statement to Agent describing the Obligation affected by such payment or reduction. No Lender shall set off against an Agent Account without Agent’s prior consent.

15.11    Remittance of Payments and Collections.

(a)Remittances Generally. All payments by any Lender to Agent shall be made by the time and on the day set forth in this Agreement, in immediately available funds. If no time for payment is specified or if payment is due on demand by Agent and request for payment is made by Agent by 1:00 p.m. on a Business Day, payment shall be made by Lender not later than 3:00 p.m. on such day, and if request is made after 1:00 p.m., then payment shall be made by 11:00 a.m. on the next Business Day. Payment by Agent to any Lender (or Bank Product Provider) shall be made by wire transfer, in the type of funds received by Agent. Any such payment shall be subject to Agent’s right of offset for any amounts due from such payee under the Loan Documents.

(b)Failure to Pay. If any Lender (or Bank Product Provider) fails to pay any amount when due by it to Agent pursuant to the terms hereof, such amount shall bear interest, from the due date until paid in full, at the greater of the Federal Funds Rate or the rate determined by Agent as customary for interbank compensation for two (2) Business Days and thereafter at the Default Rate for Base Rate Loans. In no event shall Borrowers be entitled to credit for any interest paid by a Lender (or Bank Product Provider) to Agent, nor shall a Defaulting Lender be entitled to interest on amounts held by Agent pursuant to Section 2.3(i).

(c)Recovery of Payments. If Agent pays an amount to a Lender (or Bank Product Provider) in the expectation that a related payment will be received by Agent from a Loan Party and such related payment is not received, then Agent may recover such amount from the Lender (or Bank Product Provider). If Agent determines that an amount received by it must be returned or paid to a Loan Party or other Person pursuant to applicable law or otherwise, then Agent shall not be required to distribute such amount to any Lender (or Bank Product Provider). If any amounts received and applied by Agent to Obligations held by a Lender (or Bank Product Provider) are later required to be returned by Agent pursuant to applicable law, such Lender (or Bank Product Provider) shall pay to Agent, on demand, its share of the amounts required to be returned.

15.12    Titles. Each Lender, other than Bank of America, that is designated in connection with this credit facility as a “Joint Lead Arranger” or “Joint Bookrunner” of any kind shall have no right or duty under any Loan Documents other than those applicable to all Lenders, and shall in no event have any fiduciary duty to any Lender (or any Bank Product Provider).

15.13    Bank of Product Providers. Each Bank Product Provider, by delivery of a notice (including by way of delivery of a Bank Product Provider Agreement) to Agent of a Bank Product, agrees to be bound by the Loan Documents, including Section 2.4(b)(iv), Section 18.5, Section 18.9(c) and Section 15. Each Bank Product Provider shall indemnify and hold harmless Agent-Related Persons, to the extent not reimbursed by Loan Parties, against all Applicable Claims that may be incurred by or asserted against any Agent-Related Person in connection with such provider's Bank Product Obligations.

15.14    No Third Party Beneficiaries. This Section 15 is an agreement solely among Lender (and Bank Product Providers) and Agent, and shall survive payment in full of the Obligations. This Section 15

72

does not confer any rights or benefits upon Borrowers or any other Person. As between Borrowers and Agent, any action that Agent may take under any Loan Documents or with respect to any Obligations shall be conclusively presumed to have been authorized and directed by Lenders (and Bank Product Providers).

a Participant, to the Lender granting the participation, at the time or times prescribed by law and at such time or times reasonably requested by Parent or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the IRC) and such additional documentation reasonably requested by Parent or the Agent as may be necessary for Parent and the Agent to comply with their obligations under FATCA and to determine that such Lender or Participant has complied with its obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 17.2(d), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

17.3    Reductions.

(a)If a Lender or a Participant is subject to an applicable withholding Tax, Borrowers or Agent (or, in the case of a Participant, the Lender granting the participation) may withhold from any payment to such Lender or such Participant an amount equivalent to the applicable withholding Tax. If the forms or other documentation required by Section 17.2(a) or 17.2(c) are not delivered to Agent and Parent (or, in the case of a Participant, to the Lender granting the participation), then Agent or Borrowers (or, in the case of a Participant, to the Lender granting the participation) may withhold from any payment to such Lender or such Participant not providing such forms or other documentation an amount equivalent to the applicable withholding Tax.

(b)Each Loan Party shall (subject to Section 2.15 of this Agreement) indemnify Lender or Agent, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 17) payable or paid by such Lender or Agent or required to be withheld or deducted from a payment due from or on account of any obligation of any Loan Party to such Lender or Agent and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the applicable Loan Party by such Lender (with a copy to Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(c)Each Lender shall severally indemnify Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 17) attributable to such Lender (but only to the extent that any Loan Party has not already indemnified Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 13.1(i) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by Agent shall be conclusive absent manifest error. Each Lender hereby authorizes Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by Agent to the Lender from any other source against any amount due to the Agent under this Section 17.3(c).

17.4    Refunds. If Agent or a Lender determines, in its sole discretion exercised in good faith, that it has received a refund of any Indemnified Taxes for which it has received additional amounts pursuant to this Section 17, so long as no Default or Event of Default has occurred and is continuing, it shall pay over such refund to the applicable Loan Party (but only to the extent of payments made, or additional amounts paid, by the applicable Loan Party under this Section 17 with respect to Taxes giving rise to such a refund), net of all out-of-pocket expenses of Agent or such Lender and without interest (other than any interest paid by the applicable Governmental Authority with respect to such a refund); provided, that the applicable Loan Party, upon the request of Agent or such Lender, agrees to repay the

75

amount paid over to the applicable Loan Party (plus any penalties, interest or other charges imposed by the applicable Governmental Authority, other than such penalties, interest or other charges imposed as a result of the bad faith, willful misconduct or gross negligence of Agent hereunder) to Agent or such Lender in the event Agent or such Lender is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 17.4, in no event will the Agent or Lender be required to pay any amount to a Loan Party pursuant to this Section 17.4 the payment of which would place Agent or Lender in a less favorable net after-Tax position than the Lender or Agent would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. Notwithstanding anything in this Agreement to the contrary, this Section 17.4 shall not be construed to require Agent or any Lender to make available its Tax returns (or any other information which it deems confidential) to the applicable Loan Party or any other Person.

18.    GENERAL PROVISIONS.

18.1    Effectiveness. This Agreement shall be binding and deemed effective when executed by each Borrower, Agent and each Lender whose signature is provided for on the signature pages hereof.

18.2    Section Headings. Headings and numbers have been set forth herein for convenience only. Unless the contrary is compelled by the context, everything contained in each Section applies equally to this entire Agreement.

18.3    Interpretation. Neither this Agreement nor any uncertainty or ambiguity herein shall be construed against the Lender Group or any Borrower, whether under any rule of construction or otherwise. On the contrary, this Agreement has been reviewed by all parties and shall be construed and interpreted according to the ordinary meaning of the words used so as to accomplish fairly the purposes and intentions of all parties hereto.

18.4    Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific provision.

18.5    Bank Product Providers.

(a)Each Bank Product Provider in its capacity as such shall be deemed a third party beneficiary hereof and of the provisions of the other Loan Documents for purposes of any reference in a Loan Document to the parties for whom Agent is acting. Agent hereby agrees to act as agent for such Bank Product Providers and, by virtue of entering into a Bank Product Agreement, the applicable Bank Product Provider shall be automatically deemed to have appointed Agent as its agent and to have accepted the benefits of the Loan Documents. It is understood and agreed that the rights and benefits of each Bank Product Provider under the Loan Documents consist exclusively of such Bank Product Provider’s being a beneficiary of the Liens and security interests (and, if applicable, guarantees) granted to Agent and the right to share in payments and collections out of the Collateral as more fully set forth herein. In addition, each Bank Product Provider, by virtue of entering into a Bank Product Agreement, shall be automatically deemed to have agreed that Agent shall have the right, but shall have no obligation, to establish, maintain, relax, or release reserves in respect of the Bank Product Obligations and that if reserves are established there is no obligation on the part of Agent to determine or insure whether the amount of any such reserve is appropriate or not. In connection with any such distribution of payments or proceeds of Collateral, Agent shall be entitled to assume no amounts are due or owing to any Bank Product Provider unless such Bank Product Provider has provided a written certification (setting forth a reasonably detailed calculation) to Agent as to the amounts that are due and owing to it and such written certification is received by Agent a reasonable period of time prior to the making of such distribution. Agent shall have no obligation to calculate the amount due and payable with respect to any Bank Products, but may rely upon the written certification of the amount due and payable from the applicable

76

Bank Product Provider. In the absence of an updated certification, Agent shall be entitled to assume that the amount due and payable to the applicable Bank Product Provider is the amount last certified to Agent by such Bank Product Provider (including in any Bank Product Provider Agreement) as being due and payable (less any distributions made to such Bank Product Provider on account thereof). The Borrowers may obtain Bank Products from any Bank Product Provider, although Borrowers are not required to do so. Each Borrower acknowledges and agrees that no Bank Product Provider has committed to provide any Bank Products and that the providing of Bank Products by any Bank Product Provider is in the sole and absolute discretion of such Bank Product Provider. Notwithstanding anything to the contrary in this Agreement or any other Loan Document, no provider or holder of any Bank Product shall have any voting or approval rights hereunder (or be deemed a Lender) solely by virtue of its status as the provider or holder of such agreements or products or the Obligations owing thereunder, nor shall the consent of any such provider or holder be required (other than in their capacities as Lenders, to the extent applicable) for any matter hereunder or under any of the other Loan Documents, including as to any matter relating to the Collateral or the release of Collateral or Guarantors.

(b)At any time prior to or within ten (10) days after the date of the provision of the applicable Bank Product to the Borrowers or their Subsidiaries, or in the case of a Bank Product in effect on the ClosingSecond Amendment Effective Date, at least fivetwo (52) Business Days prior to the ClosingSecond Amendment Effective Date, if the applicable Borrower or Subsidiary and the applicable Bank Product Provider desire that the monetary obligations in respect of such Bank Product Agreement be treated as “Bank Product Obligations” or, in the case of transactions under a Hedge Agreement, “Pari Secured Hedge Obligations” hereunder with rights in respect of payment of proceeds of the Collateral in accordance with the waterfall provisions set forth in Section 2.4(b)(iv), the applicable Bank Product Provider shall provide to the Agent an executed Bank Product Provider Agreement (to be acknowledged by the Agent) that specifies, (i) with respect to each Bank Product Provider Agreement that is a Hedge Agreement, whether such Hedge Agreement is to be a “Pari Secured Hedge Agreement” and treated as pari passu in priority of payment with the principal outstanding of the Revolving Loans in accordance with clause (K) of the waterfall provisions set forth in Section 2.4(b)(iv), so long as such Hedge Agreement is with any counterparty that is a Hedge Provider at the time such Hedge Agreement is entered into and (ii) the maximum amount of Bank Product Obligations to be secured by the Collateral as of the date of such Bank Product Provider Agreement (which maximum amount may be updated by further notice from the applicable Bank Product Provider to the Agent from time to time). If, in any Bank Product Provider Agreement, the applicable Hedge Provider shall fail to include that a Hedge Agreement shall constitute a Pari Secured Hedge Agreement, then such Hedge Agreement shall not constitute a Pari Secured Hedge Agreement and shall be afforded the priority of payment of proceeds of the Collateral under Section 2.4(b)(iv)(L) of the waterfall provisions. If, at any time, a Revolving Lender ceases to be a Revolving Lender under the Agreement, then, from and after the date on which it ceases to be a Revolving Lender thereunder, neither it nor any of its Affiliates shall constitute Bank Product Providers and the obligations with respect to Bank Product Agreements entered into with such former Revolving Lender or any of its Affiliates shall no longer constitute Bank Product Obligations and, if applicable, Pari Secured Hedge Obligations. If, at any time, the aggregate marked to market exposure of Pari Secured Hedge Obligations exceeds the Available Hedge Amount, then the portion of the marked to market exposure of each Pari Secured Hedge Obligation that is in excess of the Available Hedge Amount shall, for all purposes of Section 2.4(b)(iv), be treated as and deemed to be Obligations of a Bank Product Provider payable under clause (L) of Section 2.4(b)(iv) and shall be paid in accordance with the last paragraph of Section 2.4(b)(iv).

18.6    Debtor-Creditor Relationship. The relationship between the Lenders and Agent, on the one hand, and the Loan Parties, on the other hand, is solely that of creditor and debtor. No member of the Lender Group has (or shall be deemed to have) any fiduciary relationship or duty to any Loan Party arising out of or in connection with the Loan Documents or the transactions contemplated thereby, and there is no agency or joint venture relationship between the members of the Lender Group, on the one hand, and the Loan Parties, on the other hand, by virtue of any Loan Document or any transaction

77

contemplated therein. Each Lender and their affiliates may have economic interests that conflict with those of the Borrower.

18.7    Counterparts; Electronic Execution. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement. Delivery of an executed counterpart of this Agreement by telefacsimile or other electronic method of transmission shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telefacsimile or other electronic method of transmission also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. The foregoing shall apply to each other Loan Document mutatis mutandis.

18.8    Revival and Reinstatement of Obligations; Certain Waivers. If any member of the Lender Group or any Bank Product Provider repays, refunds, restores, or returns in whole or in part, any payment or property (including any proceeds of Collateral) previously paid or transferred to such member of the Lender Group or such Bank Product Provider in full or partial satisfaction of any Obligation or on account of any other obligation of any Loan Party under any Loan Document or any Bank Product Agreement, because the payment, transfer, or the incurrence of the obligation so satisfied is asserted or declared to be void, voidable, or otherwise recoverable under any applicable law relating to creditors’ rights, including provisions of the Bankruptcy Code relating to fraudulent transfers, preferences, or other voidable or recoverable obligations or transfers (each, a “Voidable Transfer”), or because such member of the Lender Group or Bank Product Provider elects to do so on the reasonable advice of its counsel in connection with a claim that the payment, transfer, or incurrence is or may be a Voidable Transfer, then, as to any such Voidable Transfer, or the amount thereof that such member of the Lender Group or Bank Product Provider elects to repay, restore, or return (including pursuant to a settlement of any claim in respect thereof), and as to all reasonable costs, expenses, and attorneys' fees of such member of the Lender Group or Bank Product Provider related thereto, (1) the liability of the Loan Parties with respect to the amount or property paid, refunded, restored, or returned will automatically and immediately be revived, reinstated, and restored and will exist and (2) Agent’s Liens securing such liability shall be effective, revived, and remain in full force and effect, in each case, as fully as if such Voidable Transfer had never been made.If, prior to any of the foregoing, (a) Agent’s Liens shall have been released or terminated or (b) any provision of this Agreement shall have been terminated or cancelled, Agent’s Liens, or such provision of this Agreement, shall be reinstated in full force and effect and such prior release, termination, cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect the obligation of any Loan Party in respect of such liability or any Collateral securing such liability.

18.9    Confidentiality.

(a)Agent and Lenders each individually (and not jointly or jointly and severally) agree that material, non-public information regarding Parent and its Subsidiaries, their operations, assets, and existing and contemplated business plans (“Confidential Information”) shall be treated by Agent and the Lenders in a confidential manner, and shall not be disclosed by Agent and the Lenders to Persons who are not parties to this Agreement, except: (i) to attorneys for and other advisors, accountants, auditors, and consultants to any member of the Lender Group and, to employees, directors and officers of any member of the Lender Group (the Persons in this clause (i) and clause (ii) below, “Lender Group Representatives”) on a “need to know” basis in connection with this Agreement and the transactions contemplated hereby and on a confidential basis, (ii) to Subsidiaries and Affiliates of any member of the Lender Group (including the Bank Product Providers) and any of their attorneys for and other advisors, accountants, auditors and consultants to any member of the Lender Group and to employees, directors and officers on a “need to know” basis in connection with this Agreement and the transactions contemplated hereby and on a confidential basis, provided that any such Person shall have agreed to receive such information hereunder subject to the terms of this Section 18.9, (iii) as may be required by

78

regulatory authorities so long as such authorities are informed of the confidential nature of such information, (iv) as may be required by statute, decision, or judicial or administrative order, rule, or regulation; provided that (x) prior to any disclosure under this clause (iv), the disclosing party agrees to provide Borrowers with prior notice thereof, to the extent that it is practicable to do so and to the extent that the disclosing party is permitted to provide such prior notice to Borrowers pursuant to the terms of the applicable statute, decision, or judicial or administrative order, rule, or regulation and (y) any disclosure under this clause (iv) shall be limited to the portion of the Confidential Information as may be required by such statute, decision, or judicial or administrative order, rule, or regulation, (v) as may be agreed to in advance in writing by Borrowers, (vi) as requested or required by any Governmental Authority pursuant to any subpoena or other legal process, provided, that, (x) prior to any disclosure under this clause (vi) the disclosing party agrees to provide Borrowers with prior written notice thereof, to the extent that it is practicable to do so and to the extent that the disclosing party is permitted to provide such prior written notice to Borrowers pursuant to the terms of the subpoena or other legal process and (y) any disclosure under this clause (vi) shall be limited to the portion of the Confidential Information as may be required by such Governmental Authority pursuant to such subpoena or other legal process, (vii) as to any such information that is or becomes generally available to the public (other than as a result of prohibited disclosure by Agent or the Lenders or the Lender Group Representatives), (viii) in connection with any assignment, participation or pledge of any Lender’s interest under this Agreement, provided that prior to receipt of Confidential Information any such assignee, participant, or pledgee shall have agreed in writing to receive such Confidential Information either subject to the terms of this Section 18.9 or pursuant to confidentiality requirements substantially similar to those contained in this Section 18.9 (and such Person may disclose such Confidential Information to Persons employed or engaged by them as described in clause (i) above), (ix) in connection with any litigation or other adversary proceeding involving parties hereto which such litigation or adversary proceeding involves claims related to the rights or duties of such parties under this Agreement or the other Loan Documents; provided, that, prior to any disclosure to any Person (other than any Loan Party, Agent, any Lender, any of their respective Affiliates, or their respective counsel) under this clause (x) with respect to litigation involving any Person (other than any Borrower, Agent, any Lender, any of their respective Affiliates, or their respective counsel), the disclosing party agrees to provide Borrowers with prior written notice thereof, and (x) in connection with, and to the extent reasonably necessary for, the exercise of any secured creditor remedy under this Agreement or under any other Loan Document. In addition, the Agent and the Lenders may disclose the existence of this Agreement and publicly available information about this Agreement to (i) any actual or prospective direct or indirect counterparty (or its advisors) to any swap or derivative transaction relating to the Borrowers or (ii) market data collectors, similar service providers to the lending industry, and service providers to the Agent and the Lenders in connection with the administration and management of this Agreement.

(b)Anything in this Agreement to the contrary notwithstanding, Agent may disclose customary information concerning the terms and conditions of this Agreement and the other Loan Documents to loan syndication and pricing reporting services or in its marketing or promotional materials, with such information to consist of deal terms and other information customarily found in such publications or marketing or promotional materials and may otherwise use the name, logos, and other insignia of any Borrower or the other Loan Parties and the Revolver Commitments provided hereunder in any “tombstone” or other advertisements, on its website or in other marketing materials of the Agent.

(c)The Loan Parties hereby acknowledge that Agent or its Affiliates may make available to the Lenders materials or information provided by or on behalf of Borrowers hereunder (collectively, “Borrower Materials”) by posting the Borrower Materials on IntraLinks, SyndTrak or another similar electronic system (the “Platform”) and certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to the Loan Parties or their securities) (each, a “Public Lender”). The Loan Parties shall be deemed to have authorized Agent and its Affiliates and the Lenders to treat Borrower Materials marked “PUBLIC” or otherwise at any time filed with the SEC as not containing any material non-public information with respect to the Loan Parties or their securities for purposes of United States federal and state securities laws. All Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform designated as

79

“Public Investor” (or another similar term). Agent and its Affiliates and the Lenders shall be entitled to treat any Borrower Materials that are not marked “PUBLIC” or that are not at any time filed with the SEC as being suitable only for posting on a portion of the Platform not marked as “Public Investor” (or such other similar term).

18.10    Survival. All representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that Agent, Issuing Bank, or any Lender may have had notice or knowledge of any Default or Event of Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of, or any accrued interest on, any Loan or any fee or any other amount payable under this Agreement is outstanding or unpaid or any Letter of Credit is outstanding and so long as the Revolver Commitments have not expired or been terminated.

18.11    Patriot Act. Each Lender that is subject to the requirements of the Patriot Act hereby notifies Borrowers that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies each Borrower, which information includes the name and address of each Borrower and other information that will allow such Lender to identify each Borrower in accordance with the Patriot Act. In addition, if Agent is required by law or regulation or internal policies to do so, it shall have the right to periodically conduct i) Patriot Act searches, OFAC/PEP searches, and customary individual background checks for the Loan Parties and ii) OFAC/PEP searches and customary individual background checks for the Loan Parties’ senior management and key principals, and each Borrower agrees to cooperate in respect of the conduct of such searches and further agrees that the reasonable costs and charges for such searches shall constitute Lender Group Expenses hereunder and be for the account of Borrowers.

18.12    Integration. This Agreement, together with the other Loan Documents, reflects the entire understanding of the parties with respect to the transactions contemplated hereby and shall not be contradicted or qualified by any other agreement, oral or written, before the date hereof. The foregoing to the contrary notwithstanding, all Bank Product Agreements, if any, are independent agreements governed by the written provisions of such Bank Product Agreements, which will remain in full force and effect, unaffected by any repayment, prepayments, acceleration, reduction, increase, or change in the terms of any credit extended hereunder, except as otherwise expressly provided in such Bank Product Agreement.

18.13    Parent as Agent for Borrowers. Each Borrower hereby irrevocably appoints Parent as the borrowing agent and attorney-in-fact for all Borrowers (the “Administrative Borrower”) which appointment shall remain in full force and effect unless and until Agent shall have received prior written notice signed by each Borrower that such appointment has been revoked and that another Borrower has been appointed Administrative Borrower. Each Borrower hereby irrevocably appoints and authorizes the Administrative Borrower i) to provide Agent with all notices with respect to Revolving Loans and Letters of Credit obtained for the benefit of any Borrower and all other notices and instructions under this Agreement and the other Loan Documents (and any notice or instruction provided by Administrative Borrower shall be deemed to be given by Borrowers hereunder and shall bind each Borrower), ii) to receive notices and instructions from members of the Lender Group (and any notice or instruction provided by any member of the Lender Group to the Administrative Borrower in accordance with the terms hereof shall be deemed to have been given to each Borrower), iii) to take such action as the Administrative Borrower deems appropriate on its behalf to obtain Revolving Loans and Letters of Credit and to exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement and (d) execute and deliver any amendments, consents, waivers or other instruments related to this Agreement and the other Loan Documents on behalf of such Borrower and any such amendment, consent, waiver or other instrument shall be binding upon and enforceable against such other Borrower to the same extent as if

80

made directly by such Borrower (but Agent shall be entitled to require execution thereof by all Borrowers). It is understood that the handling of the Loan Account and Collateral in a combined fashion, as more fully set forth herein (and subject to the terms herein), is done solely as an accommodation to the Borrowers in order to utilize the collective borrowing powers of the Borrowers in the most efficient and economical manner and at their request, and that Lender Group shall not incur liability to any Borrower as a result hereof. Each Borrower expects to derive benefit, directly or indirectly, from the handling of the Loan Account and the Collateral in a combined fashion, as more fully set forth herein (and subject to the terms herein), since the successful operation of each Borrower is dependent on the continued successful performance of the integrated group. To induce the Lender Group to do so, and in consideration thereof, each Borrower hereby jointly and severally agrees to indemnify each member of the Lender Group and holds each member of the Lender Group harmless against any and all liability, expense, loss or claim of damage or injury, made against the Lender Group by any Borrower or by any third party whosoever, arising from or incurred by reason of (i) the handling of the Loan Account and Collateral securing the Obligations as herein provided, or (ii) the Lender Group’s relying on any instructions of the Administrative Borrower, except that the Borrowers will have no liability to the relevant Agent-Related Person or Lender-Related Person under this Section 18.13 with respect to any liability that has been finally determined by a court of competent jurisdiction to have resulted solely from the bad faith, gross negligence or willful misconduct of such Agent-Related Person or Lender-Related Person, as the case may be.

18.14    Judgment Currency. If for the purpose of obtaining judgment in any court it is necessary to convert an amount due hereunder in the currency in which it is due (the “Original Currency”) into another currency (the “Second Currency”), the rate of exchange applied shall be that at which, in accordance with normal banking procedures, the Agent could purchase in the New York foreign exchange market, the Original Currency with the Second Currency on the date two (2) Business Days preceding that on which judgment is given. Each Obligor agrees that its obligation in respect of any Original Currency due from it hereunder shall, notwithstanding any judgment or payment in such other currency, be discharged only to the extent that, on the Business Day following the date the Agent receives payment of any sum so adjudged to be due hereunder in the Second Currency, the Agent may, in accordance with normal banking procedures, purchase, in the New York foreign exchange market, the Original Currency with the amount of the Second Currency so paid; and if the amount of the Original Currency so purchased or could have been so purchased is less than the amount originally due in the Original Currency, each Obligor agrees as a separate obligation and notwithstanding any such payment or judgment to indemnify the Agent against such loss. The term “rate of exchange” in this Section 18.14 means the Spot Rate at which the Agent, in accordance with normal practices, is able on the relevant date to purchase the Original Currency with the Second Currency, and includes any premium and costs of exchange payable in connection with such purchase.

18.15    Acknowledgement and Consent to Bail-In of Affected Financial Institutions. Notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any Lender that is an Affected Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

81

institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

Exhibit 95

Mine Safety Disclosures

    The operation of our mines located in the United States is subject to regulation by MSHA under the FMSH Act. MSHA inspects these mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the FMSH Act. We present information below regarding certain mining safety and health citations that MSHA has issued with respect to our mining operations. In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the mine; (ii) the number of citations issued will vary from inspector to inspector and mine to mine, and (iii) citations and orders can be contested and appealed and, in that process, are often reduced in severity and amount, and are sometimes dismissed.

    Under the Dodd-Frank Act, each operator of a coal or other mine is required to include certain mine safety results within its periodic reports filed with the SEC. As required by the reporting requirements included in §1503(a) of the Dodd-Frank Act, we present the following items regarding certain mining safety and health matters, for the period presented, for each of our mine locations that are covered under the scope of the Dodd-Frank Act:

(A)The total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under section 104 of the FMSH Act (30 U.S.C. 814) for which the operator received a citation from MSHA;

(B)The total number of orders issued under section 104(b) of the FMSH Act (30 U.S.C. 814(b));

(C)The total number of citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under section 104(d) of the FMSH Act (30 U.S.C. 814(d));

(D)The total number of imminent danger orders issued under section 107(a) of the FMSH Act (30 U.S.C. 817(a));

(E)The total dollar value of proposed assessments from MSHA under the FMSH Act (30 U.S.C. 801 et seq.);

(F)Legal actions pending before the Federal Mine Safety and Health Review Commission involving such coal or other mine as of the last day of the period;

(G)Legal actions instituted before the Federal Mine Safety and Health Review Commission involving such coal or other mine during the period; and

(H)Legal actions resolved before the Federal Mine Safety and Health Review Commission involving such coal or other mine during the period.

    During the year ended December 31, 2020, our mine locations did not receive any flagrant violations under Section 110(b)(2) of the FMSH Act (30 U.S.C. 820(b)(2)) and did not receive any written notices of a pattern of violations, or the potential to have a pattern of such violations, under section 104(e) of the FMSH Act (30 U.S.C. 814(e)). In addition, there were no mining-related fatalities at any of our mine locations during this same period.

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Business, Consolidation and Presentation

Nature of Business

Cliffs is the largest flat-rolled steel producer in North America. Founded in 1847 as a mine operator, we are also the largest producer of iron ore pellets in North America. In 2020, we acquired two major steelmakers, AK Steel and ArcelorMittal USA, vertically integrating our legacy iron ore business. Our fully-integrated portfolio includes custom-made pellets and HBI; flat-rolled carbon steel, stainless, electrical, plate, tinplate and long steel products; as well as carbon and stainless steel tubing, hot and cold stamping and tooling. Headquartered in Cleveland, Ohio, we employ approximately 25,000 people across our mining, steel and downstream manufacturing operations in the United States and Canada.

Unless otherwise noted, discussion of our business and results of operations in this Annual Report on Form 10-K refers to our continuing operations.

Acquisition of AK Steel

On March 13, 2020, we consummated the AK Steel Merger, pursuant to which, upon the terms and subject to the conditions set forth in the AK Steel Merger Agreement, Merger Sub was merged with and into AK Steel, with AK Steel surviving the AK Steel Merger as a wholly owned subsidiary of Cleveland-Cliffs Inc. Refer to NOTE 3 - ACQUISITIONS for further information.

AK Steel is a North American producer of flat-rolled carbon, stainless and electrical steel products, primarily for the automotive, infrastructure and manufacturing markets. These operations consist primarily of seven steelmaking and finishing plants, two cokemaking operations, three tube manufacturing plants and ten tooling and stamping operations. The acquisition of AK Steel transformed us into a vertically integrated producer of value-added iron ore and steel products.

Acquisition of ArcelorMittal USA

On December 9, 2020, pursuant to the terms of the AM USA Transaction Agreement, we purchased ArcelorMittal USA from ArcelorMittal. In connection with the closing of the AM USA Transaction, as contemplated by the terms of the AM USA Transaction Agreement, ArcelorMittal’s former joint venture partner in Kote and Tek exercised its put right pursuant to the terms of the Kote and Tek joint venture agreements. As a result, we purchased all of such joint venture partner’s interests in Kote and Tek. Following the closing of the AM USA Transaction, we own 100% of the interests in Kote and Tek.

The assets of ArcelorMittal USA we acquired at the closing of the AM USA Transaction include six steelmaking facilities, eight finishing facilities, three cokemaking operations, two iron ore mining and pelletizing operations and one coal mining complex.

Refer to NOTE 3 - ACQUISITIONS for further information.

Business Operations

We are vertically integrated from the mining of iron ore and coal; to production of metallics and coke; through iron making, steelmaking, rolling and finishing; and to downstream tubular components, stamping and tooling. We have the unique advantage as a steel producer of being fully or partially self-sufficient with our production of raw materials for steel manufacturing, which includes iron ore pellets, HBI and coking coal.

We have updated our segment structure to coincide with our new business model and are organized into four operating segments based on differentiated products, Steelmaking, Tubular, Tooling and Stamping, and European Operations. Through the third quarter ended September 30, 2020, we had operated through two reportable segments – the Steel and Manufacturing segment and the Mining and Pelletizing segment. However, given the recent

transformation of the business, beginning with our financial statements as of and for the year ended December 31, 2020, we primarily operate through one reportable segment – the Steelmaking segment.

COVID-19

In response to the COVID-19 pandemic, we made various operational changes to adjust to the demand for our products. Although steel and iron ore production have been considered “essential” by the states in which we operate, certain of our facilities and construction activities were temporarily idled during the second quarter of 2020. Most of these temporarily idled facilities were restarted during the second quarter, and the remaining operations were restarted during the third quarter. Dearborn Works' hot strip mill, anneal and temper operations and AK Coal remain permanently idled as part of the permanent cost reduction efforts. Our Columbus and Monessen facilities acquired through the AM USA Transaction are temporarily idled due to the COVID-19 pandemic.

Basis of Consolidation

The condensed consolidated financial statements consolidate our accounts and the accounts of our wholly owned subsidiaries, all subsidiaries in which we have a controlling interest and VIEs for which we are the primary beneficiary. All intercompany transactions and balances are eliminated upon consolidation.

Investments in Affiliates

We have investments in several businesses accounted for using the equity method of accounting. These investments are included within our Steelmaking segment. We review an investment for impairment when circumstances indicate that a loss in value below its carrying amount is other than temporary. Investees and equity ownership percentages are presented below:

Investee	Equity Ownership Percentage
Combined Metals of Chicago, LLC	40.0%
Spartan Steel Coating, LLC	48.0%

As of December 31, 2019, our 23% ownership in Hibbing was recorded as an equity method investment. As a result of the acquisition of ArcelorMittal USA, we acquired an additional 62.3% ownership interest in Hibbing. As of December 31, 2020, our ownership in the Hibbing joint venture was 85.3% and was fully consolidated within our operating results with a noncontrolling interest.

We recorded a basis difference for Spartan Steel of $33 million as part of the AK Steel Merger. The basis difference relates to the excess of the fair value over the investee's carrying amount of property, plant and equipment and will be amortized over the remaining useful lives of the underlying assets.

As of December 31, 2020, our investment in affiliates of $105 million was classified in Other non-current assets. As of December 31, 2019, our investment in affiliates of $18 million was classified in Other non-current liabilities.

Significant Accounting Policies

We consider the following policies to be beneficial in understanding the judgments involved in the preparation of our consolidated financial statements and the uncertainties that could impact our financial condition, results of operations and cash flows. Certain prior period amounts have been reclassified to conform with the current year presentation.

Use of Estimates

The preparation of financial statements in conformity with GAAP 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 revenues and expenses during the reporting period. Our mineral reserves; future realizable cash flow; environmental, reclamation and closure obligations; valuation of business combinations, long-lived assets, inventory, tax assets and post-employment, post-retirement and other employee benefit liabilities; reserves for contingencies and litigation require the use of various management estimates and assumptions. Actual results could differ from estimates. Management reviews its estimates on an ongoing basis. Changes in facts and circumstances may alter such estimates and affect the results of operations and financial position in future periods.

Business Combinations

Assets acquired and liabilities assumed in a business combination are recognized and measured based on their estimated fair values at the acquisition date, while the acquisition-related costs are expensed as incurred. Any excess of the purchase consideration when compared to the fair value of the net tangible and intangible assets acquired, if any, is recorded as goodwill. We engaged independent valuation specialists to assist with the determination of the fair value of assets acquired, liabilities assumed, noncontrolling interest, and goodwill, for the Acquisitions. If the initial accounting for the business combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded. Subsequent to the acquisition date, and not later than one year from the acquisition date, we will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the date of the acquisition. Any adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period the adjustment arises.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and on deposit as well as all short-term securities held for the primary purpose of general liquidity. We consider investments in highly liquid debt instruments with an original maturity of three months or less from the date of acquisition and longer maturities when funds can be withdrawn in three months or less without a significant penalty to be cash equivalents. We routinely monitor and evaluate counterparty credit risk related to the financial institutions in which our short-term investment securities are held.

Trade Accounts Receivable and Allowance for Credit Loss

Trade accounts receivable are recorded at the point control transfers and represent the amount of consideration we expect to receive in exchange for transferred goods and do not bear interest. We establish provisions for expected lifetime losses on accounts receivable at the time a receivable is recorded based on historical experience, customer credit quality and forecasted economic conditions. We regularly review our accounts receivable balances and the allowance for credit loss and establish or adjust the allowance as necessary using the specific identification method in accordance with CECL. We evaluate the aggregation and risk characteristics of receivable pools and develop loss rates that reflect historical collections, current forecasts of future economic conditions over the time horizon we are exposed to credit risk, and payment terms or conditions that may materially affect future forecasts.

Inventories

Inventories are generally stated at the lower of cost or net realizable value using average cost, excluding depreciation and amortization. Certain iron ore inventories are stated at the lower of cost or market using the LIFO method.

Refer to NOTE 2 - SUPPLEMENTARY FINANCIAL STATEMENT INFORMATION for further information.

Derivative Financial Instruments and Hedging Activities

We are exposed to certain risks related to the ongoing operations of our business, including those caused by changes in commodity prices and energy rates. We have established policies and procedures, including the use of certain derivative instruments, to manage such risks, if deemed necessary.

Derivative financial instruments are recognized as either assets or liabilities in the Statements of Consolidated Financial Position and measured at fair value. On the date a qualifying hedging instrument is executed, we designate the hedging instrument as a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge). We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific firm commitments or forecasted transactions. We also formally assess, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of the related hedged items. When it is determined that a derivative is not highly effective as a hedge, we discontinue hedge accounting prospectively and record all future changes in fair value in the period of the instrument's earnings or losses.

For derivative instruments that have been designated as cash flow hedges, the changes in fair value are recorded in Accumulated other comprehensive loss. Amounts recorded in Accumulated other comprehensive loss are

reclassified to earnings or losses in the period the underlying hedged transaction affects earnings or when the underlying hedged transaction is no longer reasonably possible of occurring.

For derivative instruments that have not been designated as cash flow hedges, such as provisional pricing arrangements, changes in fair value are recorded in the period of the instrument's earnings or losses.

Refer to Revenue Recognition below for discussion of derivatives recorded as a result of pricing terms in our sales contracts. Additionally, refer to NOTE 15 - DERIVATIVE INSTRUMENTS for further information.

Property, Plant and Equipment

Our properties are stated at the lower of cost less accumulated depreciation. Depreciation of plant and equipment is computed principally by the straight-line method based on estimated useful lives. Depreciation continues to be recognized when operations are idled temporarily. Depreciation and depletion are recorded over the following estimated useful lives:

Asset Class	Basis	Life
Land, land improvements and mineral rights
Land and mineral rights	Units of production	Life of mine
Land improvements	Straight line	20 to 45 years
Buildings	Straight line	20 to 45 years
Equipment	Straight line/Double declining balance	3 to 20 years

Refer to NOTE 6 - PROPERTY, PLANT AND EQUIPMENT for further information.

Goodwill

Goodwill represents the excess purchase price paid over the fair value of the net assets during an acquisition. Goodwill is not amortized, but is assessed for impairment on an annual basis on October 1 (or more frequently if necessary).

Other Intangible Assets and Liabilities

Intangible assets and liabilities are subject to periodic amortization on a straight-line basis over their estimated useful lives as follows:

Type	Basis	Useful Life
Intangible assets:
Customer relationships	Straight line	18 years
Developed technology	Straight line	17 years
Trade names and trademarks	Straight line	10 years
Mining permits	Straight line	Life of mine
Intangible liabilities:
Above-market supply contracts	Straight line	Contract term

Refer to NOTE 7 - GOODWILL AND INTANGIBLE ASSETS AND LIABILITIES for further information.

Leases

We determine if an arrangement contains a lease at inception. We recognize right-of-use assets and lease liabilities associated with leases based on the present value of the future minimum lease payments over the lease term at the commencement date. Lease terms reflect options to extend or terminate the lease when it is reasonably certain that the option will be exercised. For short-term leases (leases with an initial lease term of 12 months or less), right-of-use assets and lease liabilities are not recognized in the consolidated balance sheet, and lease expense is recognized on a straight-line basis over the lease term.

Refer to NOTE 13 - LEASE OBLIGATIONS for further information.

Asset Impairment

We monitor conditions that may affect the carrying value of our long-lived tangible and intangible assets when events and circumstances indicate that the carrying value of the asset groups may not be recoverable. In order to determine if assets have been impaired, assets are grouped and tested at the lowest level for which identifiable, independent cash flows are available ("asset group"). The measurement of the impairment loss to be recognized is based on the difference between the fair value and the carrying value of the asset group. Fair value can be determined using a market approach, income approach or cost approach.

For the years ended December 31, 2020, 2019 and 2018, no impairment indicators were present that would indicate the carrying value of any of our asset groups may not be recoverable; as a result, no impairment assessments were required.

Fair Value Measurements

ASC Topic 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for classification of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own views about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized below:

•Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 — Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

•Level 3 — Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

The classification of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement in its entirety.

Refer to NOTE 9 - FAIR VALUE OF FINANCIAL INSTRUMENTS and NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Pensions and Other Postretirement Benefits

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits as part of our total compensation and benefits programs.

We recognize the funded or unfunded status of our pension and OPEB obligations on our December 31, 2020 and 2019 Statements of Consolidated Financial Position based on the difference between the market value of plan assets and the actuarial present value of our retirement obligations on that date, on a plan-by-plan basis. If the plan assets exceed the pension and OPEB obligations, the amount of the surplus is recorded as an asset; if the pension and OPEB obligations exceed the plan assets, the amount of the underfunded obligations is recorded as a liability. Year-end balance sheet adjustments to pension and OPEB assets and obligations are recorded as Accumulated other comprehensive loss in the Statements of Consolidated Financial Position.

The actuarial estimates of the PBO and APBO incorporate various assumptions including the discount rates, the rates of increases in compensation, healthcare cost trend rates, mortality, retirement timing and employee turnover. The discount rate is determined based on the prevailing year-end rates for high-grade corporate bonds with a duration matching the expected cash flow timing of the benefit payments from the various plans. The remaining assumptions are based on our estimates of future events by incorporating historical trends and future expectations. The amount of net periodic cost that is recorded in the Statements of Consolidated Operations consists of several components including service cost, interest cost, expected return on plan assets, and amortization of previously unrecognized amounts. Service cost represents the value of the benefits earned in the current year by the participants. Interest cost represents the cost associated with the passage of time. Certain items, such as plan amendments, gains and/or losses resulting from differences between actual and assumed results for demographic

and economic factors affecting the obligations and assets of the plans, and changes in other assumptions are subject to deferred recognition for income and expense purposes. The expected return on plan assets is determined utilizing the weighted average of expected returns for plan asset investments in various asset categories based on historical performance, adjusted for current trends. Service costs are classified within Cost of goods sold, Selling, general and administrative expenses and Miscellaneous – net while the interest cost, expected return on assets, amortization of prior service costs/credits, net actuarial gain/loss, and other costs are classified within Other non-operating income.

Refer to NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Labor Agreements

At December 31, 2020, we employed approximately 25,000 people, of which approximately 18,500 were represented by labor unions under various agreements. We have agreements that will expire at five locations in 2021 and sixteen locations in 2022. Workers at some of our North American facilities are covered by agreements with the USW or other unions that have various expiration dates.

Asset Retirement Obligations

Asset retirement obligations are recognized when incurred and recorded as liabilities at fair value. The fair value of the liability is determined as the discounted value of the expected future cash flows. The asset retirement obligation is accreted over time through periodic charges to earnings. In addition, the asset retirement cost is capitalized and amortized over the life of the related asset. Reclamation costs are adjusted periodically to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. We review, on an annual basis, unless otherwise deemed necessary, the asset retirement obligation for each applicable operation in accordance with the provisions of ASC Topic 410, Asset Retirement and Environmental Obligations. We perform an in-depth evaluation of the liability every three years in addition to our routine annual assessments.

Future reclamation costs for inactive operations are accrued based on management’s best estimate at the end of each period of the costs expected to be incurred at a site. Such cost estimates include, where applicable, ongoing maintenance and monitoring costs. Changes in estimates at inactive operations are reflected in earnings in the period an estimate is revised.

Refer to NOTE 14 - ASSET RETIREMENT OBLIGATIONS for further information.

Environmental Remediation Costs

We have a formal policy for environmental protection and restoration. Certain of our operating activities are subject to various laws and regulations governing protection of the environment. We conduct our operations to protect the public health and environment and believe our operations are in compliance with applicable laws and regulations in all material respects. Our environmental liabilities, including obligations for known environmental remediation exposures, have been recognized based on the estimated cost of investigation and remediation at each site. If the cost can only be estimated as a range of possible amounts with no point in the range being more likely, the minimum of the range is accrued. Future expenditures are discounted unless the amount and timing of the cash disbursements cannot be reasonably estimated. It is possible that additional environmental obligations could be incurred, the extent of which cannot be assessed. Potential insurance recoveries have not been reflected in the determination of the liabilities.

Refer to NOTE 21 - COMMITMENTS AND CONTINGENCIES for further information.

Revenue Recognition

Sales are recognized when our performance obligations are satisfied. Generally, our performance obligations are satisfied, control of our products is transferred and revenue is recognized at a single point in time, when title transfers to our customer for product shipped according to shipping terms. Shipping and other transportation costs charged to customers are treated as fulfillment activities and are recorded in both revenue and cost of sales at the time control is transferred to the customer. Refer to NOTE 4 - REVENUES for further information.

Repairs and Maintenance

Repairs, maintenance and replacement of components are expensed as incurred. The cost of major equipment overhauls is capitalized and depreciated over the estimated useful life, which is the period until the next scheduled overhauls. All other planned and unplanned repairs and maintenance costs are expensed when incurred.

Share-Based Compensation

The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. A correlation matrix of historical and projected stock prices was developed for both the Company and its predetermined peer group of mining and metals companies. The fair value assumes that the performance objective will be achieved. The expected term of the grant represents the time from the grant date to the end of the service period. We estimate the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds, with a term commensurate with the remaining performance period.

The fair value of the restricted stock units is determined based on the closing price of our common shares on the grant date.

Upon vesting of share-based compensation awards, we issue shares from treasury shares before issuing new shares. Forfeitures are recognized when they occur.

The fair value of stock options is estimated on the date of grant using a Black-Scholes model using the grant date price of our common shares and option exercise price, and assumptions regarding the option’s expected term, the volatility of our common shares, the risk-free interest rate, and the dividend yield over the option’s expected term.

Refer to NOTE 11 - STOCK COMPENSATION PLANS for additional information.

Income Taxes

Income taxes are based on income for financial reporting purposes, calculated using tax rates by jurisdiction, and reflect a current tax liability or asset for the estimated taxes payable or recoverable on the current year tax return and expected annual changes in deferred taxes. Any interest or penalties on income tax are recognized as a component of Income tax benefit (expense).

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized within Net income (loss) in the period that includes the enactment date.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial results of operations.

Accounting for uncertainty in income taxes recognized in the financial statements requires that a tax benefit from an uncertain tax position be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on technical merits.

See NOTE 12 - INCOME TAXES for further information.

Discontinued Operations

During 2018, we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and sold all of the assets of our Asia Pacific Iron Ore business through a series of sales to third parties. As a result of our exit, management determined that our Asia Pacific Iron Ore mining operations met the criteria to be classified as held for sale and a discontinued operation under ASC Topic 205, Presentation of Financial

Statements. As such, all current and historical Asia Pacific Iron Ore operating results are classified within discontinued operations.

Foreign Currency

Our financial statements are prepared with the U.S. dollar as the reporting currency and the functional currency of all subsidiaries is the U.S. dollar, except for our European Operations for which the functional currency is the Euro. In August 2018, management determined that there were significant changes in economic factors related to our Australian subsidiaries. The change in economic factors was a result of the sale and conveyance of substantially all assets and liabilities of our Australian subsidiaries to third parties, representing a significant change in operations. As such, the functional currency for the Australian subsidiaries changed from the Australian dollar to the U.S. dollar and all remaining Australian denominated monetary balances will be remeasured prospectively through the Statements of Consolidated Operations.

As a result of the liquidation of the Australian subsidiaries' assets, the historical impact of foreign currency translation recorded in Accumulated other comprehensive loss in the Statements of Consolidated Financial Position of $228 million was reclassified and recognized as a gain in Income (loss) from discontinued operations, net of tax in the Statements of Consolidated Operations for the year ended December 31, 2018.

Earnings Per Share

We present both basic and diluted EPS amounts for continuing operations and discontinued operations. Total basic EPS amounts are calculated by dividing Net income (loss) attributable to Cliffs shareholders, less the earnings allocated to our Series B Participating Redeemable Preferred Stock, by the weighted average number of common shares outstanding during the period presented.

Total diluted EPS amounts are calculated by dividing Net income (loss) attributable to Cliffs shareholders by the weighted average number of common shares, common share equivalents under stock plans using the treasury-stock method, common share equivalents of the Series B Participating Redeemable Preferred Stock using the if-converted method and the calculated common share equivalents in excess of the conversion rate related to our 1.50% 2025 Convertible Senior Notes using the treasury-stock method. Common share equivalents are excluded from EPS computations in the periods in which they have an anti-dilutive effect.

See NOTE 8 - DEBT AND CREDIT FACILITIES and NOTE 20 - EARNINGS PER SHARE for further information.

Variable Interest Entities

We assess whether we have a variable interest in legal entities in which we have a financial relationship and, if so, whether or not those entities are VIEs. A VIE is an entity with insufficient equity at risk for the entity to finance its activities without additional subordinated financial support or in which equity investors lack the characteristics of a controlling financial interest. If an entity is determined to be a VIE, we evaluate whether we are the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. We conclude that we are the primary beneficiary and consolidate the VIE if we have both (i) the power to direct the activities of the VIE that most significantly influence the VIE's economic performance and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Refer to NOTE 19 - VARIABLE INTEREST ENTITIES for additional information.

Recent Accounting Pronouncements

Issued and Adopted

On March 2, 2020, the SEC issued a final rule that amended the disclosure requirements related to certain registered securities under SEC Regulation S-X, Rule 3-10, which required separate financial statements for subsidiary issuers and guarantors of registered debt securities unless certain exceptions are met. The final rule replaces the previous requirement under Rule 3-10 to provide condensed consolidating financial information in the registrant’s financial statements with a requirement to provide alternative financial disclosures (which include summarized financial information of the parent and any issuers and guarantors, as well as other qualitative disclosures) in either the registrant’s Management's Discussion and Analysis of Financial Condition and Results of Operations or its financial statements, in addition to other simplifications. The final rule is effective for filings on or after January 4, 2021, and early adoption is permitted. We elected to early adopt this disclosure update for the period ended March 31, 2020. As a result, we have excluded the footnote disclosures required under the previous Rule 3-10, and applied the final rule by including the summarized financial information and qualitative disclosures in Part II -

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of this Annual Report on Form 10-K and Exhibit 22, filed herewith.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except for short-term leases. For lessees, leases are classified as either operating or finance leases. We adopted this standard on its effective date of January 1, 2019 using the optional alternative approach, which requires application of the new guidance at the beginning of the standard's effective date. Adoption of the updated standard did not have a material effect on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which introduces a new accounting model, CECL. CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. CECL utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. We elected to early adopt this standard on December 31, 2019. Upon adoption, the updated standard did not have a material effect on our consolidated financial statements.

Issued and Not Effective

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). This update requires certain convertible instruments to be accounted for as a single liability measured at its amortized cost. Additionally, the update requires the use of the "if-converted" method, removing the treasury stock method, when calculating diluted shares. The two methods of adoption are the full and modified retrospective approaches. We expect to utilize the modified retrospective approach. Using this approach, the guidance shall be applied to transactions outstanding as of the beginning of the fiscal year in which the amendment is adopted. The final rule is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We are continuing to evaluate the impact of this update to our consolidated financial statements and would expect to adopt at the required adoption date of January 1, 2022.

Business Combinations [Abstract]

Business Combination Disclosure

In 2020, we acquired two major steelmakers, AK Steel and ArcelorMittal USA, vertically integrating our legacy iron ore business with steel production. Our fully-integrated portfolio includes custom-made pellets and HBI; flat-rolled carbon steel, stainless, electrical, plate, tinplate and long steel products; as well as carbon and stainless steel tubing, hot and cold stamping and tooling. The AK Steel Merger combined Cliffs, a producer of iron ore pellets, with AK Steel, a producer of flat-rolled carbon, stainless and electrical steel products, to create a vertically integrated producer of value-added iron ore and steel products. The AM USA Transaction transformed us into a fully-integrated steel enterprise with the size and scale to achieve improved through-the-cycle margins.

We now have a presence across the entire steel manufacturing process, from mining to pelletizing to the development and production of finished high value steel products. The combination is expected to create significant opportunities to generate additional value from market trends across the entire steel value chain and enable more consistent, predictable performance through normal market cycles.

Acquisition of ArcelorMittal USA

Overview

On December 9, 2020, pursuant to the terms of the AM USA Transaction Agreement, we purchased ArcelorMittal USA from ArcelorMittal. In connection with the closing of the AM USA Transaction, as contemplated by the terms of the AM USA Transaction Agreement, ArcelorMittal’s former joint venture partner in Kote and Tek exercised its put right pursuant to the terms of the Kote and Tek joint venture agreements. As a result, we purchased all of such joint venture partner’s interests in Kote and Tek. Following the closing of the AM USA Transaction, we own 100% of the interests in Kote and Tek.

Following the acquisition, the operating results of ArcelorMittal USA are included in our consolidated financial statements. For the period subsequent to the acquisition (December 9, 2020 through December 31, 2020), ArcelorMittal USA generated Revenues of $446 million and a loss of $40 million included within Net income (loss) attributable to Cliffs shareholders, which included $21 million related to amortization of the fair value inventory step-up.

Additionally, we incurred acquisition-related costs excluding severance costs of $26 million for the year ended December 31, 2020, which were recorded in Acquisition-related costs on the Statements of Consolidated Operations.

The AM USA Transaction was accounted for under the acquisition method of accounting for business combinations.

The fair value of the total purchase consideration was determined as follows:

	(In Millions)
Fair value of Cliffs common shares issued	$	990

Valuation Assumption and Preliminary Purchase Price Allocation

We estimated fair values at December 9, 2020 for the preliminary allocation of consideration to the net tangible and intangible assets acquired and liabilities assumed in connection with the AM USA Transaction. During the measurement period, we will continue to obtain information to assist in finalizing the fair value of assets acquired and liabilities assumed, which may differ materially from these preliminary estimates. If we determine any measurement period adjustments are material, we will apply those adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. We are in the process of conducting a valuation of the assets acquired and liabilities assumed related to the AM USA Transaction, most notably, inventories, personal and real property, mineral reserves, leases, investments, deferred taxes, asset retirement obligations, pension and OPEB liabilities, and the final allocation will be made when completed, including the result of any identified goodwill. Accordingly, the provisional measurements noted below are preliminary and subject to modification in the future.

The preliminary purchase price allocation to assets acquired and liabilities assumed in the AM USA Transaction was:

	(In Millions)
Cash and cash equivalents	$	35

The goodwill resulting from the acquisition of ArcelorMittal USA primarily represents the growth opportunities in the automotive, construction, appliances, infrastructure and machinery and equipment markets, as well as any synergistic benefits to be realized from the AM USA Transaction and was assigned to our flat steel operations within our Steelmaking segment. Goodwill is expected to be deductible for U.S. federal income tax purposes.

Acquisition of AK Steel

Overview

On March 13, 2020, pursuant to the AK Steel Merger Agreement, we completed the acquisition of AK Steel, in which we were the acquirer. As a result of the AK Steel Merger, each share of AK Steel common stock issued and outstanding immediately prior to the effective time of the AK Steel Merger (other than excluded shares) was converted into the right to receive 0.400 Cliffs common shares and, if applicable, cash in lieu of any fractional Cliffs common shares.

Following the acquisition, the operating results of AK Steel are included in our consolidated financial statements. For the period subsequent to the acquisition (March 13, 2020 through December 31, 2020), AK Steel generated Revenues of $3,573 million and a loss of $302 million included within Net income (loss) attributable to Cliffs shareholders, which included $74 million and $35 million related to amortization of the fair value inventory step-up and severance costs, respectively.

Additionally, we incurred acquisition-related costs excluding severance costs of $26 million for the year ended December 31, 2020, which were recorded in Acquisition-related costs on the Statements of Consolidated Operations.

Refer to NOTE 8 - DEBT AND CREDIT FACILITIES for information regarding debt transactions executed in connection with the AK Steel Merger.

The AK Steel Merger was accounted for under the acquisition method of accounting for business combinations. The acquisition date fair value of the consideration transferred totaled $1,535 million. The following tables summarize the consideration paid for AK Steel and the estimated fair values of the assets acquired and liabilities assumed at the acquisition date.

The fair value of the total purchase consideration was determined as follows:

	(In Millions)
Fair value of AK Steel debt	$	914

Total purchase consideration	$	1,535

The fair value of Cliffs common shares issued for outstanding shares of AK Steel common stock and with respect to Cliffs common shares underlying converted AK Steel equity awards that vested upon completion of the AK Steel Merger is calculated as follows:

	(In Millions, Except Per Share Amounts)
Number of shares of AK Steel common stock issued and outstanding	317
Exchange ratio	0.400
Shares of Cliffs common shares issued to AK Steel stockholders	127
Price per share of Cliffs common shares	$	4.87

	(In Millions)
Credit Facility	$	590
7.50% Senior Secured Notes due July 2023	324
Fair value of debt included in consideration	$	914

Valuation Assumption and Preliminary Purchase Price Allocation

We estimated fair values at March 13, 2020 for the preliminary allocation of consideration to the net tangible and intangible assets acquired and liabilities assumed in connection with the AK Steel Merger. During the measurement period, we will continue to obtain information to assist in finalizing the fair value of assets acquired and liabilities assumed, which may differ materially from these preliminary estimates. If we determine any measurement period adjustments are material, we will apply those adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. We are in the process of conducting a valuation of the assets acquired and liabilities assumed related to the AK Steel Merger, most notably, personal and real property, leases, deferred taxes, asset retirement obligations and intangible assets and liabilities, and the final allocation will be made when completed, including the result of any identified goodwill. Accordingly, the provisional measurements noted below are preliminary and subject to modification in the future.

The preliminary purchase price allocation to assets acquired and liabilities assumed in the AK Steel Merger was:

	(In Millions)
	Initial Allocation of Consideration		Measurement Period Adjustments		Updated Allocation
Cash and cash equivalents	$	38	$	1	$	39

Goodwill	141		33		174
Total net assets acquired	$	1,535	$	—	$	1,535

During the period subsequent to the AK Steel Merger, we made certain measurement period adjustments to the acquired assets and liabilities assumed due to clarification of information utilized to determine fair value during the measurement period. The Inventories measurement period adjustments of $243 million resulted in a favorable impact of $8 million to Cost of goods sold for the year ended December 31, 2020.

The goodwill resulting from the acquisition of AK Steel was assigned to our downstream Tubular and Tooling and Stamping operating segments. Goodwill is calculated as the excess of the purchase price over the net identifiable assets recognized and primarily represents the growth opportunities in light weighting solutions to automotive customers, as well as any synergistic benefits to be realized. Goodwill from the AK Steel Merger is not expected be deductible for income tax purposes.

The preliminary purchase price allocated to identifiable intangible assets and liabilities acquired was:

	(In Millions)		Weighted Average Life (In Years)
Intangible assets:
Customer relationships	$	77	18
Developed technology	60		17
Trade names and trademarks	11		10
Total identifiable intangible assets	$	148	17
Intangible liabilities:
Above-market supply contracts	$	(71)	12

The above-market supply contracts relate to the long-term coke and energy supply agreements with SunCoke Energy, which includes SunCoke Middletown, a consolidated VIE. Refer to NOTE 19 - VARIABLE INTEREST ENTITIES for further information.

Pro Forma Results

The following table provides unaudited pro forma financial information, prepared in accordance with Topic 805, for the years ended December 31, 2020 and 2019, as if ArcelorMittal USA and AK Steel had been acquired as of January 1, 2019:

	(In Millions)
	Year Ended December 31,
	2020		2019
Revenues	$	12,837	$	17,163
Net income (loss) attributable to Cliffs shareholders	(520)		(11)

The unaudited pro forma financial information has been calculated after applying our accounting policies and adjusting the historical results with pro forma adjustments, net of tax, that assume the Acquisitions occurred on January 1, 2019. Significant pro forma adjustments include the following:

1.The elimination of intercompany revenues between Cliffs and ArcelorMittal USA and AK Steel of $844 million and $1,499 million for the years ended December 31, 2020 and 2019, respectively.

2.The 2020 pro forma net loss was adjusted to exclude $96 million of non-recurring inventory acquisition accounting adjustments incurred during the year ended December 31, 2020. The 2019 pro forma net loss was adjusted to include $362 million of non-recurring inventory acquisition accounting adjustments for the year ended December 31, 2019.

3.The elimination of non-recurring transaction costs incurred by Cliffs, AK Steel and ArcelorMittal USA in connection with the Acquisitions were $93 million for the year ended December 31, 2020. The 2019 pro forma net loss was adjusted to include $93 million of non-recurring transaction cost adjustments for the year ended December 31, 2019.

4.The 2020 pro forma net loss was adjusted to exclude restructuring costs of $1,820 million of non-recurring costs incurred by ArcelorMittal USA prior to the AM USA Transaction.

5.The 2020 and 2019 pro forma net losses were adjusted to exclude $140 million and $129 million for the years ended December 31, 2020 and 2019, respectively, for the impact of reversal of the fees charged for management, financial and legal services under the Industrial Franchise Agreement with the former parent.

6.Total other pro forma adjustments included reduced expenses of $32 million for the year ended December 31, 2020, primarily due to decreased depreciation expense and pension and OPEB expense, offset partially by increased interest and amortization expense.

7.Total other pro forma adjustments included an expense of $76 million for the year ended December 31, 2019, primarily due to increased interest, amortization and pension and OPEB expense, offset partially by decreased depreciation expense.

8.The income tax impact of pro forma transaction adjustments that affect Net income (loss) attributable to Cliffs shareholders at a statutory rate of 24.3% resulted in an increased benefit to Income tax benefit (expense) of $170 million and $117 million for the years ended December 31, 2020 and 2019, respectively.

The unaudited pro forma financial information does not reflect the potential realization of synergies or cost savings, nor does it reflect other costs relating to the integration of the acquired companies. This unaudited pro forma financial information should not be considered indicative of the results that would have actually occurred if the Acquisitions had been consummated on January 1, 2019, nor are they indicative of future results.

REVENUES

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

We generate our revenue through product sales, in which shipping terms generally indicate when we have fulfilled our performance obligations and transferred control of products to our customer. Our revenue transactions consist of a single performance obligation to transfer promised goods. Our contracts with customers usually define the mechanism for determining the sales price, which is generally fixed upon transfer of control, but the contracts generally do not impose a specific quantity on either party. Quantities to be delivered to the customer are generally determined at a point near the date of delivery through purchase orders or other written instructions we receive from the customer. Spot market sales are made through purchase orders or other written instructions. We consider our performance obligation to be complete and recognize revenue when control transfers in accordance with shipping terms.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring product. We reduce the amount of revenue recognized for estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized. Payment terms are consistent with terms standard to the markets we serve. Sales taxes collected from customers are excluded from revenues.

Prior to the AM USA Transaction, we had a supply agreement with ArcelorMittal USA, which included supplemental revenue or refunds based on the HRC price in the year the iron ore was consumed in ArcelorMittal USA's blast furnaces. As control transferred prior to consumption, the supplemental revenue was recorded in accordance with Topic 815. All sales occurring subsequent to the AM USA Transaction are intercompany and eliminated in consolidation. Included within Revenues related to Topic 815 for the supplemental revenue portion of the supply agreement is derivative revenue of $122 million, $78 million and $426 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Prior to the AK Steel Merger, our iron ore pellet sales agreement with Severstal Dearborn, LLC, subsequently assumed by AK Steel, required supplemental payments to be paid by the customer during the period from 2009 through 2013. Installment amounts received under this arrangement in excess of sales were classified as deferred revenue in the Statements of Consolidated Financial Position upon receipt of payment and the revenue was recognized over the term of the supply agreement, which had extended until 2022, in equal annual installments. As a result of the termination of that iron ore pellet sales agreement, we realized $35 million of deferred revenue, which was recognized within Realization of deferred revenue in the Statements of Consolidated Operations during the year ended December 31, 2020.

We have certain other sales agreements that require customers to pay in advance. Payments received pursuant to these agreements prior to revenue being recognized are recorded as deferred revenue in Other current liabilities.

SEGMENT REPORTING

Segment Reporting [Abstract]

SEGMENT REPORTING

We are vertically integrated from the mining of iron ore and coal; to production of metallics and coke; through iron making, steelmaking, rolling, finishing; and to downstream tubing, stamping and tooling. We are organized into four operating segments based on our differentiated products - Steelmaking, Tubular, Tooling and Stamping, and European Operations. Our previous Mining and Pelletizing segment is included within the Steelmaking operating segment as iron ore pellets are a primary raw material for our steel products. We have one reportable segment - Steelmaking. The operating segment results of our Tubular, Tooling and Stamping, and European Operations that do not constitute reportable segments are combined and disclosed in the Other Businesses category. Our Steelmaking

segment is the largest flat-rolled steel producer supported by being the largest iron ore pellet producer in North America, primarily serving the automotive, infrastructure and manufacturing, and distributors and converters markets. Our Other Businesses primarily include the operating segments that provide customer solutions with carbon and stainless steel tubing products, advanced-engineered solutions, tool design and build, hot- and cold-stamped steel components, and complex assemblies. All intersegment transactions were eliminated in consolidation.

We evaluate performance on an operating segment basis, as well as a consolidated basis, based on Adjusted EBITDA, which is a non-GAAP measure. This measure is used by management, investors, lenders and other external users of our financial statements to assess our operating performance and to compare operating performance to other companies in the steel industry. In addition, management believes Adjusted EBITDA is a useful measure to assess the earnings power of the business without the impact of capital structure and can be used to assess our ability to service debt and fund future capital expenditures in the business.

Outstanding Senior Unsecured Notes

Cliffs Senior Notes exchanged for AK Steel Corporation Senior Notes

On March 16, 2020, we entered into indentures, in each case among Cliffs, the guarantors party thereto and U.S. Bank National Association, as trustee, relating to the issuance by Cliffs of $232 million aggregate principal amount of 6.375% 2025 Senior Notes and $335 million aggregate principal amount of 7.00% 2027 Senior Notes. The new notes were issued in exchange for equal aggregate principal amounts of 6.375% 2025 AK Senior Notes and 7.00% 2027 AK Senior Notes, respectively, issued by AK Steel Corporation. The 6.375% 2025 Senior Notes and 7.00% 2027 Senior Notes were issued in connection with the AK Steel Merger pursuant to private exchange offers exempt from the registration requirements of the Securities Act made by Cliffs. Pursuant to the registration rights agreements executed in connection with the issuance of the new notes, we agreed to file registration statements with the SEC with respect to registered offers to exchange the 6.375% 2025 Senior Notes and 7.00% 2027 Senior Notes for publicly registered notes within 365 days of the closing date, with all significant terms and conditions remaining the same.

The 6.375% 2025 Senior Notes and 7.00% 2027 Senior Notes are unsecured obligations and rank equally in right of payment with all of our existing and future unsecured and unsubordinated indebtedness. The notes are guaranteed on a senior unsecured basis by our material direct and indirect wholly owned domestic subsidiaries and, therefore, are structurally senior to any of our existing and future indebtedness that is not guaranteed by such guarantors and are structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries that do not guarantee the notes.

In addition, if a change in control triggering event, as defined in the indentures, occurs with respect to the 6.375% 2025 Senior Notes or 7.00% 2027 Senior Notes, we will be required to offer to purchase the notes at a purchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of purchase.

1.50% 2025 Convertible Senior Notes

The 1.50% 2025 Convertible Senior Notes bear interest at a rate of 1.50% per year, payable semiannually in arrears on January 15 and July 15 of each year. The 1.50% 2025 Convertible Senior Notes mature on January 15, 2025. The 1.50% 2025 Convertible Senior Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the 1.50% 2025 Convertible Senior Notes; equal in right of payment to any of our unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The terms of the 1.50% 2025 Convertible Senior Notes contain certain customary covenants; however, there are no financial covenants.

Holders may convert their 1.50% 2025 Convertible Senior Notes at their option at any time prior to the close of business on the business day immediately preceding July 15, 2024, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2018, if the last reported sale price of our common shares, par value $0.125 per share, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business day period after any five-consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 1.50% 2025 Convertible Senior Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common shares and the conversion rate on each such trading day; (3) if we call the notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after July 15, 2024 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their 1.50% 2025 Convertible Senior Notes at any time, regardless of the foregoing circumstances. Upon conversion, we will pay or deliver, as the case may be, cash, common shares or a combination of cash and common shares, at our election.

Upon the issuance of the 1.50% 2025 Convertible Senior Notes the initial conversion rate was 122.4365 common shares per $1,000 principal, with a conversion price of $8.17 per common share. The conversion rate is subject to adjustment in some circumstances, including the payment of dividends on common shares, but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its 1.50% 2025 Convertible Senior Notes in connection with such a corporate event or notice of redemption, as the case may be. As of December 31, 2020, the conversion rate was 129.2985 common shares per $1,000 principal amount of 1.50% 2025 Convertible Senior Notes.

We may not redeem the 1.50% 2025 Convertible Senior Notes prior to January 15, 2022. We may redeem all or any portion of the 1.50% 2025 Convertible Senior Notes, for cash at our option on or after January 15, 2022 if the last reported sale price of our common shares has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30-consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the 1.50% 2025 Convertible Senior Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

It is our current intent to settle conversions through combination settlement or fully in cash.  Our ability to settle conversions through combination settlement and cash settlement will be subject to restrictions in the agreement governing our ABL Facility and may be subject to restrictions in agreements governing our future debt.

If we undergo a fundamental change as defined in the indenture, holders may require us to repurchase for cash all or any portion of their 1.50% 2025 Convertible Senior Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 1.50% 2025 Convertible Senior Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the notes, we separated the 1.50% 2025 Convertible Senior Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that did not have associated convertible features. The carrying amount of the equity component of $86 million representing the conversion option was determined by deducting the fair value of the liability component from the par value of the notes. The difference represents the debt discount that is amortized to interest expense over the term of the notes. The equity component is not remeasured as long as it continues to qualify for equity classification.

Other Outstanding Unsecured Senior Notes

The following represents a summary of our other unsecured senior notes' maturity and interest payable due dates:

Debt Instrument	Maturity	Interest Payable (until maturity)
5.75% 2025 Senior Notes	March 1, 2025	March 1 and September 1
5.875% 2027 Senior Notes	June 1, 2027	June 1 and December 1
6.25% 2040 Senior Notes	October 1, 2040	April 1 and October 1

The senior notes are unsecured obligations and rank equally in right of payment with all our other existing and future unsecured and unsubordinated indebtedness. There are no subsidiary guarantees of the interest and principal amounts for the 6.25% 2040 Senior Notes. The 5.75% 2025 Senior Notes and 5.875% 2027 Senior Notes are guaranteed on a senior unsecured basis by our material direct and indirect wholly owned domestic subsidiaries and, therefore, are structurally senior to any of our existing and future indebtedness that is not guaranteed by such guarantors and are structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries that do not guarantee the 5.75% 2025 Senior Notes and 5.875% 2027 Senior Notes.

We may redeem the 5.75% 2025 Senior Notes, in whole or in part, on or after March 1, 2020, at the redemption prices set forth in the indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption.

We may redeem the 5.875% 2027 Senior Notes, in whole or in part, on or after June 1, 2022, at the redemption prices set forth in the indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, and prior to June 1, 2022, at a redemption price equal to 100% of the principal amount thereof plus a “make-whole” premium set forth in the indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. We may also redeem up to 35% of the aggregate principal amount of the 5.875% 2027 Senior Notes on or prior to June 1, 2022 at a redemption price equal to 105.875% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of redemption with the net cash proceeds of one or more equity offerings.

The 6.25% 2040 Senior Notes may be redeemed any time at our option upon not less than 30, nor more than 60, days' prior notice is sent to the holders. The 6.25% 2040 Senior Notes are redeemable at a redemption price equal to the greater of (1) 100% of the principal amount of the notes to be redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted to the redemption date on a semi-annual basis at the treasury rate plus 40 basis points, plus accrued and unpaid interest, if any, to, but not including, the date of redemption.

In addition, if a change of control triggering event, as defined in the applicable indenture, occurs with respect to the unsecured notes, we will be required to offer to purchase the notes of the applicable series at a purchase price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of purchase.

The terms of the unsecured notes contain certain customary covenants; however, there are no financial covenants.

ABL Facility

On March 13, 2020, in connection with the AK Steel Merger, we entered into a new ABL Facility with various financial institutions to replace and refinance Cliffs’ Former ABL Facility and AK Steel Corporation’s former revolving credit facility. The ABL Facility will mature upon the earlier of March 13, 2025 or 91 days prior to the maturity of certain other material debt and provided for up to $2 billion in borrowings, including a $555 million sublimit for the issuance of letters of credit and a $125 million sublimit for swingline loans. Availability under the ABL Facility is limited to an eligible borrowing base, as applicable, determined by applying customary advance rates to eligible accounts receivable, inventory and certain mobile equipment.

On March 27, 2020, the ABL Facility was amended, by and among Cliffs, the lenders and the administrative agent. The amendment modified the ABL Facility to, among other things, provide for a new FILO tranche B of commitments in the aggregate amount of $150 million by exchanging existing commitments under the ABL Facility. The total commitments under the ABL Facility after giving effect to the amendment remained at $2 billion. The terms and conditions (other than the pricing) that apply to the FILO tranche are substantially the same as the terms and conditions that apply to the tranche A facility of the ABL Facility immediately prior to the amendment.

On December 9, 2020, we entered into the ABL Amendment with various financial institutions. The ABL Amendment modified the ABL Facility to, among other things, increase the amount of tranche A revolver commitments available thereunder by an additional $1.5 billion and increase certain dollar baskets related to certain negative covenants that apply to the ABL Facility. After giving effect to the ABL Amendment, the aggregate principal amount of tranche A revolver commitments under the ABL Facility is $3.35 billion and the aggregate principal amount of FILO tranche B revolver commitments under the ABL Facility remains at $150 million.

The ABL Facility and certain bank products and hedge obligations are guaranteed by certain of our existing wholly owned U.S. subsidiaries and are required to be guaranteed by certain of our future U.S. subsidiaries. Amounts outstanding under the ABL Facility are secured by (i) a first-priority security interest in the accounts receivable and other rights to payment, inventory, as-extracted collateral, certain investment property, deposit accounts, securities accounts, certain general intangibles and commercial tort claims, certain mobile equipment, commodities accounts and other related assets of ours, the other borrowers and the guarantors, and proceeds and products of each of the foregoing (collectively, the “ABL Collateral”) and (ii) a second-priority security interest in substantially all of our assets and the assets of the other borrowers and the guarantors other than the ABL Collateral.

Borrowings under the ABL Facility bear interest, at our option, at a base rate or, if certain conditions are met, a LIBOR rate, in each case plus an applicable margin. We may amend our ABL Facility to replace the LIBOR rate with one or more secured overnight financing based rates or an alternative benchmark rate, giving consideration to any evolving or then-existing convention for similar dollar denominated syndicated credit facilities for such alternative benchmarks.

The ABL Facility contains customary representations and warranties and affirmative and negative covenants including, among others, covenants regarding the maintenance of certain financial ratios if certain conditions are triggered, covenants relating to financial reporting, covenants relating to the payment of dividends on, or purchase or redemption of, our capital stock, covenants relating to the incurrence or prepayment of certain debt, covenants relating to the incurrence of liens or encumbrances, covenants relating to compliance with laws, covenants relating to transactions with affiliates, covenants relating to mergers and sales of all or substantially all of our assets and limitations on changes in the nature of our business.

The ABL Facility provides for customary events of default, including, among other things, the event of nonpayment of principal, interest, fees or other amounts, a representation or warranty proving to have been materially incorrect when made, failure to perform or observe certain covenants within a specified period of time, a cross-default to certain material indebtedness, the bankruptcy or insolvency of the Company and certain of its subsidiaries, monetary judgment defaults of a specified amount, invalidity of any loan documentation, a change of control of the Company, and ERISA defaults resulting in liability of a specified amount. If an event of default exists (beyond any applicable grace or cure period), the administrative agent may, and at the direction of the requisite number of lenders shall, declare all amounts owing under the ABL Facility immediately due and payable, terminate such lenders’ commitments to make loans under the ABL Facility and/or exercise any and all remedies and other rights under the ABL Facility. For certain events of default related to insolvency and receivership, the commitments of the lenders will be automatically terminated and all outstanding loans and other amounts will become immediately due and payable.

As of December 31, 2020 and 2019, we were in compliance with the ABL Facility liquidity requirements and, therefore, the springing financial covenant requiring a minimum fixed charge coverage ratio of 1.0 to 1.0 was not applicable.

The following represents a summary of our borrowing capacity under the ABL Facility:

	(In Millions)
	December 31, 2020
Available borrowing base on ABL Facility1	$	3,500
Borrowings	(1,510)
Letter of credit obligations2	(247)
Borrowing capacity available	$	1,743
1 As of December 31, 2020, the ABL Facility has a maximum borrowing base of $3.5 billion. The available borrowing base is determined by applying customary advance rates to eligible accounts receivable, inventory and certain mobile equipment.
2 We issued standby letters of credit with certain financial institutions in order to support business obligations including, but not limited to, workers' compensation, employee severance, insurance, operating agreements, IRBs and environmental obligations.

Other Financing Arrangements

Industrial Revenue Bonds

AK Steel Corporation had outstanding $66 million aggregate principal amount of fixed-rate, tax-exempt IRBs as of December 31, 2020. The weighted-average fixed rate of these IRBs is 6.86%. These IRBs are unsecured senior debt obligations that are equal in ranking with AK Steel Corporation's senior notes and AK Steel Corporation's guarantees of Cliffs' unsubordinated indebtedness. These IRBs are effectively subordinated to AK Steel Corporation’s guarantees of Cliffs’ secured indebtedness to the extent of the value of AK Steel Corporation’s assets securing such guarantees. In addition, AK Steel Corporation had outstanding $26 million aggregate principal amount of variable-rate IRBs as of December 31, 2020 that are backed by a letter of credit. These IRBs contain certain customary covenants; however, there are no financial covenants.

EDC Revolving Facility

On November 9, 2020, our Canadian subsidiaries Fleetwood Metal Industries Inc. and The Electromac Group Inc. entered into a new revolving facility with Export Development Canada. The EDC Revolving Facility enables our Tooling and Stamping business to finance the purchase of tooling and related equipment to manufacture and process long lead-time parts for our automotive customers. The EDC Revolving Facility provides for up to $40 million in borrowings and expires in November 2022. Borrowings under the EDC Revolving Facility bear interest at a LIBOR rate plus a base rate. The EDC Revolving Facility is secured by the assets of Fleetwood Metal Industries Inc. and The Electromac Group Inc. and fully guaranteed by Cliffs. As of December 31, 2020, we had outstanding borrowings on the EDC Revolving Facility of $18 million.

Debt Extinguishment - 2020

During the year ended December 31, 2020, we used the net proceeds from the offering of the additional 9.875% 2025 Senior Secured Notes to repurchase $736 million aggregate principal amount of our outstanding senior notes of various series, which resulted in a net debt reduction of $181 million. We also repurchased an additional $35 million aggregate principal amount of our outstanding senior notes of various series and we redeemed $7 million aggregate principal amount of our outstanding 2020 IRBs, with cash on hand.

Additionally, in connection with the AK Steel Merger, we purchased $364 million aggregate principal amount of 7.625% 2021 AK Senior Notes and $311 million aggregate principal amount of 7.50% 2023 AK Senior Notes upon early settlement of tender offers made by Cliffs. The net proceeds from the offering of 6.75% 2026 Senior Secured Notes, along with a portion of the ABL Facility borrowings, were used to fund such purchases. As the 7.625% 2021 AK Senior Notes and 7.50% 2023 AK Senior Notes were recorded at fair value just prior to being purchased, there was no gain or loss on extinguishment. Additionally, in connection with the final settlement of the tender offers, we purchased $9 million aggregate principal amount of the 7.625% 2021 AK Senior Notes and $56 million aggregate principal amount of the 7.50% 2023 AK Senior Notes with cash on hand.

The following is a summary of the debt extinguished and the respective impact on extinguishment:

We intend to use the net proceeds to us from the underwritten public offering of our common shares, plus cash on hand, to redeem up to approximately $334 million aggregate principal amount of our outstanding 9.875% 2025 Senior Secured Notes. We intend to use any remaining net proceeds from the underwritten public offering of our common shares following such redemption to reduce borrowings under our ABL Facility.

FAIR VALUE OF FINANCIAL INSTRUMENTS

There were no significant assets or liabilities measured at fair value as of December 31, 2020. The following represents the assets and liabilities measured at fair value as of December 31, 2019:

The valuation of financial assets classified in Level 2 was determined using a market approach based upon quoted prices for similar assets in active markets, or other inputs that were observable.

Our supply agreement with ArcelorMittal USA contained provisions for supplemental revenue or refunds based on the HRC price in the year the iron ore product was consumed in ArcelorMittal USA’s blast furnaces. We accounted for these provisions as derivative instruments at the time of sale and adjusted the derivative instruments to fair value through Revenues each reporting period until the product was consumed and the amounts were settled. These instruments were classified as Level 3 assets. Upon the completion of the AM USA Transaction, the outstanding derivatives were settled as part of acquisition accounting.

The following tables represent a reconciliation of the changes in fair value of financial instruments measured at fair value on a recurring basis using significant unobservable inputs (Level 3):

PENSIONS AND OTHER POSTRETIREMENT BENEFITS

Postemployment Benefits [Abstract]

PENSION AND OTHER POSTRETIREMENT BENEFITS

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans to a significant portion of our employees and retirees. Benefits are also provided through multiemployer plans for certain union members.

As a result of the acquisitions of AK Steel and ArcelorMittal USA, we assumed the obligations under their defined benefit pension plans, OPEB plans, defined contribution plans and commitments to multiemployer pension plans according to collective bargaining agreements that cover certain union-represented employees. The AK Steel defined benefit pension plans and OPEB plans acquired amounted to a benefit obligation, net of assets of $949 million based on a March 13, 2020 measurement. The ArcelorMittal USA defined benefit pension plans and OPEB plans acquired amounted to a benefit obligation, net of assets of $3,294 million based on a December 9, 2020 measurement.

Defined Benefit Pension Plans

The defined benefit pension plans are largely noncontributory and limited in participation. Most plans are closed to new participants with only the legacy iron ore hourly and salaried plans still open. The pension benefit

calculations vary by plan, but are generally based on employee's years of service and compensation or a fixed rate and years of service. Certain salaried plans calculate benefits using a cash balance formula, which earns interest credits and allocations based on a percent of pay.

OPEB Plans

We offer postretirement health care and life insurance benefits to retirees through various plans. The vast majority of our plans are closed to new participants. In lieu of retiree medical coverage, many union-represented employees receive a 401(k) contribution per hour worked to a restricted Retiree Health Care Account. Cost sharing features between the employer and retiree vary by plan and several plans include employer caps. Retiree healthcare coverage is provided through programs administered by insurance companies whose charges are based on benefits paid. Certain labor agreements require the funding of VEBAs, which, depending on funding levels, may be used to reimburse the employer for paid benefits.

Certain agreements with plans holding VEBA assets have capped healthcare costs. For the ArcelorMittal USA VEBA, depending on funding levels and/or Company profits, we may withdraw money from the VEBA plans to the extent funds are available for costs in excess of the cap. The 2021 expected pension contributions include $118 million in deferred 2020 pension contributions in connection with the CARES Act that were paid on January 4, 2021.

Assumptions

The discount rates used to measure plan liabilities as of the December 31 measurement date are determined individually for each plan. The discount rates are determined by matching the projected cash flows used to determine the plan liabilities to a projected yield curve of high-quality corporate bonds available at the measurement date. Discount rates for expense are calculated using the granular approach for each plan.

Depending on the plan, we use either company-specific base mortality tables or tables issued by the Society of Actuaries. We adopted the Pri-2012 mortality tables from the Society of Actuaries in 2019. On December 31, 2020, the assumed mortality improvement projection was updated from generational scale MP-2019 to generational scale MP-2020 for the Pri-2012 mortality tables.

The following represents weighted-average assumptions used to determine benefit obligations:

Plan Assets

Our financial objectives with respect to our pension and VEBA assets are to fully fund the actuarial accrued liability for each of the plans, to maximize investment returns within reasonable and prudent levels of risk, and to maintain sufficient liquidity to meet benefit obligations on a timely basis.

Our investment objective is to outperform the expected return on assets assumption used in the plans’ actuarial reports over the life of the plans. The expected return on assets takes into account historical returns and estimated future long-term returns based on capital market assumptions applied to the asset allocation strategy. The expected return is net of investment expenses paid by the plans. In addition, investment performance is monitored on a quarterly basis by benchmarking to various indices and metrics for the one-, three- and five-year periods.

The asset allocation strategy is determined through a detailed analysis of assets and liabilities by plan, which defines the overall risk that is acceptable with regard to the expected level and variability of portfolio returns, surplus (assets compared to liabilities), contributions and pension expense.

    The asset allocation review process involves simulating capital market behaviors including global asset class performance, inflation and interest rates in order to evaluate various asset allocation scenarios and determine the asset mix with the highest likelihood of meeting financial objectives. The process includes factoring in the current funded status and likely future funded status levels of the plans by taking into account expected growth or decline in the contributions over time.

The asset allocation strategy varies by plan. The following table reflects the actual asset allocations for pension and VEBA assets as of December 31, 2020 and 2019, as well as the 2021 weighted average target asset allocations. Equity investments include securities in large-cap, mid-cap and small-cap companies located in the U.S. and worldwide. Fixed income investments primarily include corporate bonds and government debt securities.

As a practical expedient, in accordance with ASC 820-10, certain investments that are measured at fair value using the NAV per share have not been classified in the fair value hierarchy below. NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by its number of shares outstanding.

Following is a description of the inputs and valuation methodologies used to measure the fair value of our plan assets.

Equity Securities

Equity securities classified as Level 1 investments include U.S. large-, small- and mid-cap investments and international equities. These investments are comprised of securities listed on an exchange, market or automated quotation system for which quotations are readily available. The valuation of these securities is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets.

Fixed Income

Fixed income securities classified as Level 1 investments include bonds, government debt securities and cash equivalents. These investments are comprised of securities listed on an exchange, market or automated

quotation system for which quotations are readily available. The valuation of these securities is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets. Also included in fixed income is a portfolio of U.S. Treasury STRIPS, which are zero-coupon bearing fixed income securities backed by the full faith and credit of the U.S. government. The securities sell at a discount to par because there are no incremental coupon payments. STRIPS are not issued directly by the Treasury, but rather are created by a financial institution, government securities broker or government securities dealer. Liquidity on the issue varies depending on various market conditions; however, in general, the STRIPS market is slightly less liquid than that of the U.S. Treasury Bond market. The STRIPS are priced daily through a bond pricing vendor and are classified as Level 2.

Hedge Funds

Hedge funds are alternative investments comprised of direct or indirect investment in offshore hedge funds with an investment objective to achieve equity-like returns with one half the volatility of equities and moderate correlation. The valuation techniques used to measure fair value attempt to maximize the use of observable inputs and minimize the use of unobservable inputs. Considerable judgment is required to interpret the factors used to develop estimates of fair value. Valuations of the underlying investment funds are obtained and reviewed. The securities that are valued by the funds are interests in the investment funds and not the underlying holdings of such investment funds. Thus, the inputs used to value the investments in each of the underlying funds may differ from the inputs used to value the underlying holdings of such funds. Hedge funds are valued monthly and recorded on a one-month lag.

Private Equity Funds

Private equity funds are alternative investments that represent direct or indirect investments in partnerships, venture funds or a diversified pool of private investment vehicles (fund of funds).

Investment commitments are made in private equity funds based on an asset allocation strategy, and capital calls are made over the life of the funds to fund the commitments. As of December 31, 2020, remaining commitments total $86 million for our pension and OPEB plans. Committed amounts are funded from plan assets when capital calls are made. Investment commitments are not pre-funded in reserve accounts.

Private equity investments are valued quarterly and recorded on a one-quarter lag. For private equity investment values reported on a lag, current market information is reviewed for any material changes in values at the reporting date. Capital distributions for the funds do not occur on a regular frequency. Liquidation of these investments would require sale of the partnership interest.

Structured Credit

Structured credit funds provide flexibility and access to both complex and illiquid premiums by investing across global, public and private residential, commercial, corporate and specialty credit markets that are priced based on valuations provided by independent, third-party pricing agents, if available. Such values generally reflect the last reported sales price if the security is actively traded. The third-party pricing agents may also value structured credit investments at an evaluated bid price by employing methodologies that utilize actual market transactions, broker-supplied valuations or other methodologies designed to identify the market value of such securities.

Structured credit investments are valued monthly and certain funds have an initial lock-up period and withdrawal restrictions on a semi-annual and quarterly basis. For structured credit investment values reported on a lag, current market information is reviewed for any material changes in values at the reporting date.

Real Estate

The real estate portfolio for the pension plans is an alternative investment comprised of funds with strategic categories of real estate investments. All real estate holdings are appraised externally at least annually, and appraisals are conducted by reputable, independent appraisal firms that are members of the Appraisal Institute. All external appraisals are performed in accordance with the Uniform Standards of Professional Appraisal Practices. The property valuations and assumptions about each property are reviewed quarterly by the investment manager and values are adjusted if there has been a significant change in circumstances relating to the property since the last external appraisal. The fair values of the funds are updated on either a monthly or quarterly basis. Redemption requests are considered on a quarterly basis, subject to notice requirements.

The real estate fund of funds investment for the Empire-Tilden, Hibbing and United Taconite VEBA plans invests in pooled investment vehicles that, in turn, invest in commercial real estate properties. Valuations are performed quarterly and financial statements are prepared on a semi-annual basis, with annual audited statements.

Asset values for this fund are reported with a one-quarter lag, and current market information is reviewed for any material changes in values at the reporting date. Withdrawals are permitted on the last business day of each quarter subject to a 95-day prior written notice.

Absolute Return Fixed Income

Absolute return fixed income investments consist of a global fixed income fund with the investment objective of generating positive absolute returns over a full market cycle. The fund's investments in securities, forward exchange contracts and futures contracts are reported at fair value on a recurring monthly basis. The fund's trustee values securities based upon independent pricing sources and futures contracts are valued at closing settled prices. Redemptions of the fund at NAV are permitted monthly under most circumstances.

Defined Contribution Plans

Most employees are eligible to participate in various defined contribution plans. Certain of these plans have features with matching contributions or other Company contributions based on our financial results. Company contributions to these plans are expensed as incurred. Total expense from these plans was $22 million, $3 million and $3 million in 2020, 2019 and 2018, respectively.

Multiemployer Plans

We contribute to multiemployer pension plans according to collective bargaining agreements that cover certain union-represented employees. The following risks of participating in these multiemployer plans differ from single employer pension plans:

•Employer contributions to a multiemployer plan may be used to provide benefits to employees of other participating employers.

•If a participating employer stops contributing to a multiemployer plan, the remaining participating employers may need to assume the unfunded obligations of the plan.

•If the multiemployer plan becomes significantly underfunded or is unable to pay its benefits, we may be required to contribute additional amounts in excess of the rate required by the collective bargaining agreements.

•If we choose to stop participating in a multiemployer plan, we may be required to pay that plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

We are a party to five collective bargaining agreements at our Ashland Works, Mansfield Works, United Taconite, Tubular Components and the majority of our ArcelorMittal USA locations that require contributions to the Steelworkers Pension Trust.

We are a party to three collective bargaining agreements at Butler Works, Middletown Works and Zanesville Works that require contributions to the International Association of Machinists and Aerospace Workers ("IAM") National Pension Fund's National Pension Plan. The plan voluntarily elected to place itself in the "Red Zone" in April 2019 and has implemented a rehabilitation plan.

Share-based Payment Arrangement [Abstract]

STOCK COMPENSATION PLANS

At December 31, 2020, we had outstanding awards under two share-based compensation plans: the A&R 2015 Equity Plan and the 2012 Amended Equity Plan. On March 13, 2020, the maximum number of shares that may be issued under the A&R 2015 Equity Plan increased by 5.7 million common shares in relation to the outstanding AK Steel stock-based incentive awards that we converted at a 0.400 rate of exchange. The converted stock-based incentive awards include 2.0 million stock options, 1.0 million long-term performance plan awards, 0.5 million performance shares, 0.2 million restricted stock awards and 0.3 million restricted stock units. As of December 31, 2020, there were 4.9 million remaining shares available for grant under the A&R 2015 Equity Plan. No additional grants were issued from the 2012 Amended Equity Plan after the date of approval of the A&R 2015 Equity Plan; however, all awards previously granted under the 2012 Amended Equity Plan will continue in accordance with the terms of the outstanding awards.

The 2.5 million awards granted in 2020 include 1.0 million long-term performance plan awards and 0.5 million performance shares relating to the AK Steel replacement awards. As of December 31, 2020, 0.3 million long-term performance plan awards and 0.1 million performance shares were outstanding as a result of qualifying termination events that triggered accelerated performance share payouts and prorated long-term performance plan awards payouts at target. The long-term performance plan awards are based on a three-year Adjusted EBITDA metric. The weighted average grant date fair value for the converted performance awards was $4.59 per share.

The outstanding performance shares vest over a period of three years and are intended to be paid out in common shares. Performance is measured on the basis of relative TSR for the period and measured against the constituents of the S&P Metals and Mining ETF Index. The number of shares actually earned at the end of the three-year period will vary, based on performance, from 0% to 200% of the number of performance shares granted.

The 1.2 million restricted stock units granted in 2020 include 0.2 million restricted stock awards relating to AK Steel replacement awards. The restricted stock awards relating to AK Steel vest ratably on the first, second and third anniversaries of the grant. We valued the restricted stock awards and restricted stock units at $4.87 per share using the closing price of our common shares on March 13, 2020, the grant date.

All of the outstanding restricted stock units are subject to continued employment, are retention based, and are payable in common shares or cash in certain circumstances at a time determined by the Compensation Committee at its discretion. The restricted stock units that were granted in 2020, 2019 and 2018 cliff vest over three years on December 31, 2022, December 31, 2021 and December 31, 2020, respectively.

Stock options granted to date generally vest over a period from one to three years with an expiration date at ten years from the date of grant. On March 13, 2020, we granted 2.0 million options as AK Steel replacement awards. The weighted average fair value of the converted options was $0.51 per share and was calculated using the Black-Scholes option-pricing model. Qualifying termination events resulted in vest date accelerations and reductions to the option expiration date from ten years to three years.

The total intrinsic value of options exercised in 2020 and 2018 were immaterial. For options outstanding at December 31, 2020, the weighted-average remaining contractual life was 3.2 years and the aggregate intrinsic value was $11 million. For options exercisable at December 31, 2020, the weighted-average remaining contractual life was 2.5 years and the aggregate intrinsic value was $9 million.

Nonemployee Directors

Our nonemployee directors are entitled to receive restricted share awards under the Directors’ Plan. For 2020, 2019 and 2018, nonemployee directors were granted a specified number of restricted shares, with a value equal to $100,000. The number of shares is based on the closing price of our common shares on the date of the Annual Meeting. The restricted share awards issued under the Directors' Plan generally vest 12 months from the grant date. The awards are subject to any deferral election and the terms of the Directors’ Plan and an award agreement.

On March 13, 2020, 0.3 million restricted stock units previously awarded to the members of the AK Steel board of directors were distributed per the terms of the AK Steel Merger Agreement.

For the last three years, grants of restricted and/or deferred shares have been awarded to elected or re-elected nonemployee directors as follows:

Year of Grant	Restricted Shares	Deferred Shares

The increase in income tax benefit from 2019 to 2020 is directly correlated to the increase in pre-tax book loss from the prior period for both federal and state income tax purposes. The other primary driver of the increase in income tax benefit is related to income of noncontrolling interests for which no tax is recognized.

The increase in income tax expense from 2018 to 2019 is primarily due to release of the valuation allowance in the U.S. of $461 million in 2018, which did not recur in 2019. The Luxembourg legal entity reduction relates to initiatives resulting in the dissolution of certain entities and settlement of related financial instruments in the years ended December 31, 2019 and 2018. These 2019 and 2018 NOL deferred tax asset reductions resulted in tax expense of $846 million and $162 million, respectively, which were fully offset by decreases in the respective valuation allowance.

We had gross domestic (including states) and foreign NOLs of $7,444 million and $1,592 million, respectively, at December 31, 2020. We had gross domestic and foreign NOLs of $3,459 million and $1,592 million, respectively, at December 31, 2019. The U.S. federal NOLs will begin to expire in 2034 and state NOLs will begin to expire in 2021. The foreign NOLs can be carried forward indefinitely. We had foreign tax credit carryforwards of $6 million at December 31, 2019, which expired in 2020. We had gross interest expense limitation carryforwards of $80 million and $55 million for the years ended December 31, 2020 and 2019, respectively. This interest expense can be carried forward indefinitely.

The changes in the valuation allowance are presented below:

During 2020, we recorded a $398 million valuation allowance through opening balance sheet adjustments to reflect the portion of federal and state NOLs that are limited under Section 382 of the IRC acquired through the AK Steel Merger.

During 2019, a legal entity reduction initiative was completed in Luxembourg resulting in the dissolution of certain entities and settlement of related financial instruments, triggering the utilization of $1.3 billion of NOL deferred tax asset and reversal of the intercompany notes deferred tax liability of $447 million. In addition, prior year adjustments in Luxembourg and a statutory rate reduction from 26.01% to 24.94% resulted in a net increase to the operating loss carryforward deferred tax asset of $46 million. The total net deferred tax reduction resulted in an expense of $846 million which was fully offset by a decrease in the valuation allowance. During 2018, a similar legal entity reduction initiative was completed resulting in the dissolution of certain Luxembourg entities which resulted in a decrease in the NOL deferred tax asset of $162 million which was fully offset by a decrease in valuation allowance. We continue to maintain a full valuation allowance against the remaining Luxembourg net deferred tax assets of $397 million at December 31, 2020 and 2019. Our losses in Luxembourg in recent periods represent sufficient negative evidence to require a full valuation allowance against the deferred tax assets in that jurisdiction. We intend

to maintain a valuation allowance against the deferred tax assets related to these operating losses, until sufficient positive evidence exists to support the realization of such assets.

We recorded a $696 million net decrease in the valuation allowance in the year ended December 31, 2018. As of December 31, 2018, our U.S. operations emerged from a three-year cumulative loss position. As the significant negative evidence of cumulative losses had been eliminated, we undertook an evaluation of the continuing need for a valuation allowance on the U.S. deferred tax assets, the majority of which related to the U.S. tax NOLs.

In completing our evaluation of whether a valuation allowance was still needed, we considered all available positive and negative evidence. Positive evidence considered included the emergence from the three-year cumulative loss position, our long-term customer contracts with minimum tonnage requirements, the global scarcity of iron ore pellets, near term forecasts of strong profitability and the recently revised IRC Section 163(j) interest deduction limitation. Negative evidence included the overall size of the deferred tax asset with limited carryforward and no carryback opportunity, the finite nature of the iron ore resources we mine, the uncertainty of steel tariffs that positively impacted our revenue rates in 2018 and the various market signs that the U.S. economy may be nearing the end of the current expansion.

We also considered that future realization of the deferred tax assets depends on the existence of sufficient taxable income of the appropriate character during the carryforward period. In considering sources of taxable income, we identified that a portion of the deferred tax assets would be utilized by existing taxable temporary differences reversing in the same periods as existing deductible temporary differences. In addition, we determined that carryback opportunities and tax planning strategies do not exist as potential sources of future taxable income. Lastly, forecasting future taxable income was considered, but was challenging in a cyclical industry such as ours as it relies heavily on the accuracy of key assumptions, particularly about key pricing benchmarks.

Because historical information is verifiable and more objective than forecast information and due to the cyclicality of the industry, we developed an estimate of future income based on our historical earnings through the most recent industry cycle. We adjusted historical earnings for certain non-recurring items as well as to reflect the current corporate structure by eliminating the impact of discontinued operations and extinguished debt (“core earnings”). Additionally, we adjusted core earnings to reflect the impact of the recently revised IRC Section 163(j) interest expense deduction limitation as well as permanent tax adjustments. The IRC Section 163(j) limitation would limit our interest expense deduction, particularly in down years in the industry cycle, resulting in higher taxable income.

Based on the core earnings analysis, our average annual book taxable income through the business cycle was in excess of the estimated $10 million taxable income that would be required annually to fully utilize the deferred tax assets within the 19-year carryforward period. We ascribed significant weight in our assessment to the core earnings analysis and the resulting projection of taxable income through the industry cycle. Based on the weight of this positive evidence, and after considering the other available positive and negative evidence, we determined that it was appropriate to release all of the valuation allowance related to U.S. federal deferred tax assets at December 31, 2018 as it was more likely than not that the entire amount of the U.S. deferred tax asset would be realized before the end of the carryforward period. The income tax benefit recorded for the reversal of the valuation allowance against the U.S. deferred tax assets was $461 million for the year ended December 31, 2018.

We also have a valuation allowance recorded against certain state NOLs and foreign tax credits, which are expected to expire before utilization. At December 31, 2020 and 2019, we had a valuation allowance recorded against certain state NOLs of $98 million and $38 million, respectively. At December 31, 2019, we had a valuation allowance recorded against certain foreign tax credits of $6 million, which expired in 2020.

At December 31, 2020 and 2019, we had no cumulative undistributed earnings of foreign subsidiaries included in retained earnings. Accordingly, no provision has been made for U.S. deferred taxes related to future repatriation of earnings.

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

	(In Millions)
	2020		2019		2018
Unrecognized tax benefits balance as of January 1	$	29	$	29	$	33

Lapses in statutes of limitations	—		—		(8)
Increases from acquisitions	75		—		—
Unrecognized tax benefits balance as of December 31	$	107	$	29	$	29

At December 31, 2020 and 2019, we had $107 million and $29 million, respectively, of unrecognized tax benefits recorded. Of this amount, $9 million was recorded in Other current liabilities for the year ended December 31, 2020. Additionally, $2 million and $4 million, were recorded in Other non-current liabilities for the years ended December 31, 2020 and 2019, respectively, and $96 million was recorded in Other non-current assets for both years in the Statements of Consolidated Financial Position. If the unrecognized tax benefits were recognized, the entire $11 million would impact the effective tax rate. We do not expect that the amount of unrecognized benefits will change significantly within the next 12 months. At December 31, 2020 and 2019, we had $1 million and $4 million, respectively, of accrued interest and penalties related to the unrecognized tax benefits recorded in Other non-current liabilities in the Statements of Consolidated Financial Position.

Tax years 2016 and forward remain subject to examination for the U.S., and tax years 2008 and forward remain subject to examination for Canada.

Leases [Abstract]

LEASE OBLIGATIONS

Our operating leases consist primarily of leases for office space, iron ore vessels, rail cars, processing equipment and mining equipment. Our finance leases consist primarily of processing equipment and mining equipment. We use our incremental borrowing rate as the discount rate to determine the present value of the lease payments, as our leases do not have readily determinable implicit discount rates. Our incremental borrowing rate is the rate of interest that we would have to borrow on a collateralized basis over a similar term and amount in a similar economic environment to pay our lease obligations. We determine the incremental borrowing rates for our leases by adjusting the local risk-free interest rate with a credit risk premium corresponding to our credit rating. From time to time, we may enter into arrangements for the construction or purchase of an asset and then enter into a financing arrangement to lease the asset. We recognize leased assets and liabilities under these arrangements when we obtain control of the asset.

Asset Retirement Obligation Disclosure

The following is a summary of our asset retirement obligations:

Long-term asset retirement obligations	$	335	$	163
1 Includes $190 million and $22 million related to our active operations as of December 31, 2020 and 2019, respectively.

The accrued closure obligation provides for contractual and legal obligations related to our indefinitely idled and closed operations and for the eventual closure of our active operations. We performed a detailed assessment of our asset retirement obligations related to our active operations most recently in 2020 in accordance with our

accounting policy, which requires us to perform an in-depth evaluation of the liability every three years in addition to routine annual assessments. In 2020, we employed third-party specialists to assist in the evaluation.

Additionally, we have included in our asset retirement obligation $172 million for our integrated steel facilities and other operations acquired in the Acquisitions. The closure date for each of our active mine sites was determined based on the exhaustion date of the remaining mineral reserves and the amortization of the related asset and accretion of the liability is recognized over the estimated mine lives. The closure date and expected timing of the capital requirements to meet our obligations for our indefinitely idled or closed mines is determined based on the unique circumstances of each property. For indefinitely idled or closed mines, the accretion of the liability is recognized over the anticipated timing of remediation. As the majority of our asset retirement obligations at our steelmaking operations have indeterminate settlement dates, asset retirement obligations have been recorded at present values using estimated ranges of the economic lives of the underlying assets.

The following is a roll-forward of our asset retirement obligation liability:

DERIVATIVE INSTRUMENTS

Derivatives Not Designated as Hedging Instruments

Customer Supply Agreement

A supply agreement with ArcelorMittal USA provided us supplemental revenue or provided refunds to ArcelorMittal USA based on the HRC price at the time the iron ore product was consumed in its blast furnaces. The supplemental pricing is characterized as a freestanding derivative instrument and is required to be accounted for separately once control transfers to the customer. The derivative instrument, which is finalized based on a future price, is adjusted to fair value through Revenues each reporting period based upon current market data and forward-looking estimates provided by management until the pellets are consumed and the amounts are settled. Upon the completion of the AM USA Transaction, the outstanding derivatives were settled as part of acquisition accounting. Included within Revenues related to Topic 815 for the supplemental revenue portion of the supply agreement is derivative revenue of $122 million, $78 million and $426 million for the years ended December 31, 2020, 2019 and 2018, respectively.

CAPITAL STOCK

Acquisition of AK Steel

As more fully described in NOTE 3 - ACQUISITIONS, we acquired AK Steel on March 13, 2020. At the effective time of the AK Steel Merger, each share of AK Steel common stock issued and outstanding prior to the effective time of the AK Steel Merger was converted into, and became exchangeable for, 0.400 Cliffs common shares, par value $0.125 per share. We issued a total of 127 million Cliffs common shares in connection with the AK Steel Merger at a fair value of $618 million. Following the closing of the AK Steel Merger, AK Steel's common stock was de-listed from the NYSE.

Acquisition of ArcelorMittal USA

As more fully described in NOTE 3 - ACQUISITIONS, we acquired ArcelorMittal USA on December 9, 2020. Pursuant to the terms of the AM USA Transaction Agreement, we issued 78,186,671 common shares and 583,273 shares of a new series of our Serial Preferred Stock, Class B, without par value, designated as the “Series B Participating Redeemable Preferred Stock,” in each case to an indirect, wholly owned subsidiary of ArcelorMittal as part of the consideration paid by us in connection with the closing of the AM USA Transaction. Refer to Preferred Stock below for further information.

Preferred Stock

We have 3,000,000 shares of Serial Preferred Stock, Class A, without par value and 4,000,000 shares of Serial Preferred Stock, Class B, without par value, authorized; no Class A preferred shares are issued or outstanding. Pursuant to the terms of the AM USA Transaction Agreement, we issued 583,273 shares of a new series of our Serial Preferred Stock, Class B, without par value, designated Series B Participating Redeemable Preferred Stock, without par value, to an indirect, wholly owned subsidiary of ArcelorMittal on December 9, 2020.

Series B Participating Redeemable Preferred Stock Terms

The Series B Participating Redeemable Preferred Stock is classified for accounting purposes as temporary equity as a result of a change in control provision that could, under remote circumstances, require us to redeem the preferred stock for cash.

The Series B Participating Redeemable Preferred Stock ranks senior to our common shares with respect to dividend rights and rights on the distribution of assets upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of, and certain bankruptcy events involving, Cliffs. Each share of Series B Participating Redeemable Preferred Stock entitles its holder to receive a multiple, initially equal to 100 (subject to certain anti-dilution adjustments, the “Applicable Multiple”), of the aggregate amount per share of all dividends declared on the common shares. In addition, from and after the 24-month anniversary of the issue date of the Series B Participating Redeemable Preferred Stock (the “24-Month Anniversary”), each holder of a share of Series B Participating Redeemable Preferred Stock is entitled to receive cash dividends (the “Additional Dividends”) accruing and compounding on a daily basis at the initial rate of 10% per annum on the sum of (i) the Applicable Multiple then in effect times the volume-weighted average price of the common shares for the 20 consecutive trading days ending on the trading day immediately preceding the 24-Month Anniversary and (ii) the amount of accumulated and unpaid dividends on the Series B Participating Redeemable Preferred Stock to, but not including, the 24-Month Anniversary, if any, which rate will increase by 2% per annum at the end of each six-month period following the 24-Month Anniversary. Additional Dividends will be payable, when, as and if declared by the Board, in quarterly installments.

The Series B Participating Redeemable Preferred Stock is redeemable, in whole or in part, at our option at any time and from time to time on and after the date that is 180 days after the issue date at a redemption price per share equal to the Applicable Multiple then in effect times the volume-weighted average price of the common shares for the 20 consecutive trading days ending on the trading day immediately preceding the date fixed for redemption, plus accumulated and unpaid dividends to, but not including, the redemption date.

In the event of a change of control of Cliffs, the Series B Participating Redeemable Preferred Stock will be subject to mandatory redemption at a redemption price per share equal to the Applicable Multiple then in effect times the volume-weighted average price of the common shares for the 20 consecutive trading days ending on the trading day immediately preceding the closing date of the transaction constituting such change of control.

In addition, pursuant to the terms of the Series B Participating Redeemable Preferred Stock, we are restricted from effecting any merger or consolidation with or into another entity unless the Series B Participating Redeemable Preferred Stock remains outstanding following the merger or consolidation, is exchanged for new preferred stock with substantially identical terms or is to be redeemed in connection with the closing of such merger or consolidation.

In addition to the foregoing, the Series B Participating Redeemable Preferred Stock is subject to the express terms of the Serial Preferred Stock, Class B, without par value, as set forth in Cleveland-Cliffs Inc.’s Fourth Amended Articles of Incorporation, as amended, except that holders of Series B Participating Redeemable Preferred Stock, in their capacity as such, do not have the right to vote with the other series of Serial Preferred Stock, Class B, without par value, then outstanding, if any, voting separately as a class, for the election of additional directors of Cleveland-Cliffs Inc. upon certain defaults by the Company in the payment of dividends, as provided in Cleveland-Cliffs Inc.’s Fourth Amended Articles of Incorporation, as amended.

Subsequent to the dividend paid on April 15, 2020, our Board temporarily suspended future dividends as a result of the COVID-19 pandemic in order to preserve cash during this time of economic uncertainty.

Share Repurchase Program

In November 2018, we announced that our Board of Directors authorized a program to repurchase outstanding common shares in the open market or in privately negotiated transactions, up to a maximum of $200 million, excluding commissions and fees. In April 2019, we announced that our Board of Directors increased the common share repurchase authorization by an additional $100 million, excluding commissions and fees. During 2019, we repurchased 24 million common shares at a cost of $253 million in the aggregate, including commissions and fees. The share repurchase program was effective until December 31, 2019.

COMMITMENTS AND CONTINGENCIES

12 Months Ended

Dec. 31, 2020

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

Purchase Commitments

We purchase portions of the principal raw materials required for our steel manufacturing operations under annual and multi-year agreements, some of which have minimum quantity requirements. We also use large volumes of natural gas, electricity and industrial gases in our steel manufacturing operations. We negotiate most of our purchases of chrome, industrial gases and a portion of our electricity under multi-year agreements. Our purchases of coke are made under annual or multi-year agreements with periodic price adjustments. We typically purchase coal under annual fixed-price agreements. We also purchase certain transportation services under multi-year contracts with minimum quantity requirements.

Contingencies

We are currently the subject of, or party to, various claims and legal proceedings incidental to our current and historical operations. These claims and legal proceedings are subject to inherent uncertainties and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, additional funding requirements or an injunction. If an unfavorable ruling were to occur, there exists the possibility of a material adverse effect on the financial position and results of operations for the period in which the ruling occurs or future periods. However, based on currently available information we do not believe that any pending claims or legal proceedings will result in a material adverse effect in relation to our consolidated financial statements.

Environmental Contingencies

Although we believe our operating practices have been consistent with prevailing industry standards, hazardous materials may have been released at operating sites or third-party sites in the past, including operating sites that we no longer own. If we reasonably can, we estimate potential remediation expenditures for those sites where future remediation efforts are probable based on identified conditions, regulatory requirements, or contractual obligations arising from the sale of a business or facility. For sites involving government required investigations, we typically make an estimate of potential remediation expenditures only after the investigation is complete and when we better understand the nature and scope of the remediation. In general, the material factors in these estimates include the costs associated with investigations, delineations, risk assessments, remedial work, governmental response and oversight, site monitoring, and preparation of reports to the appropriate environmental agencies.

The following is a summary of our environmental obligations:

	(In Millions)
	December 31, 2020		December 31, 2019
Environmental obligations	$	135	$	2
Less current portion	18		—
Long-term environmental obligations	$	117	$	2

We cannot predict the ultimate costs for each site with certainty because of the evolving nature of the investigation and remediation process. Rather, to estimate the probable costs, we must make certain assumptions. The most significant of these assumptions is for the nature and scope of the work that will be necessary to investigate and remediate a particular site and the cost of that work. Other significant assumptions include the cleanup technology that will be used, whether and to what extent any other parties will participate in paying the investigation and remediation costs, reimbursement of past response costs and future oversight costs by governmental agencies, and the reaction of the governing environmental agencies to the proposed work plans. Costs for future investigation

and remediation are not discounted to their present value, unless the amount and timing of the cash disbursements are readily known. To the extent that we have been able to reasonably estimate future liabilities, we do not believe that there is a reasonable possibility that we will incur a loss or losses that exceed the amounts we accrued for the environmental matters discussed below that would, either individually or in the aggregate, have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, since we recognize amounts in the consolidated financial statements in accordance with GAAP that exclude potential losses that are not probable or that may not be currently estimable, the ultimate costs of these environmental matters may be higher than the liabilities we currently have recorded in our consolidated financial statements.

Pursuant to RCRA, which governs the treatment, handling and disposal of hazardous waste, the EPA and authorized state environmental agencies may conduct inspections of RCRA-regulated facilities to identify areas where there have been releases of hazardous waste or hazardous constituents into the environment and may order the facilities to take corrective action to remediate such releases. Likewise, the EPA or the states may require closure or post-closure care of residual, industrial and hazardous waste management units, including, but not limited to, landfills and deep injection wells. Environmental regulators have the authority to inspect all of our facilities. While we cannot predict the future actions of these regulators, it is possible that they may identify conditions in future inspections of these facilities that they believe require corrective action.

Pursuant to CERCLA, the EPA and state environmental authorities have conducted site investigations at some of our facilities and other third-party facilities, portions of which previously may have been used for disposal of materials that are currently regulated. The results of these investigations are still pending, and we could be directed to spend funds for remedial activities at the former disposal areas. Because of the uncertain status of these investigations, however, we cannot reasonably predict whether or when such spending might be required or its magnitude.

On April 29, 2002, AK Steel entered a mutually agreed-upon administrative order with the consent of the EPA pursuant to Section 122 of CERCLA to perform a RI/FS of the Hamilton plant site located in New Miami, Ohio. The plant ceased operations in 1990 and all of its former structures have been demolished. AK Steel submitted the investigation portion of the RI/FS and completed supplemental studies. Until the RI/FS is complete, we cannot reasonably estimate the additional costs, if any, we may incur for potentially required remediation of the site or when we may incur them.

EPA Administrative Order In Re: Ashland Coke

On September 26, 2012, the EPA issued an order under Section 3013 of RCRA requiring a plan to be developed for investigation of four areas at the Ashland Works coke plant. The Ashland Works coke plant ceased operations in 2011 and all of its former structures have been demolished and removed. In 1981, AK Steel acquired the plant from Honeywell International Corporation (as successor to Allied Corporation), who had managed the coking operations there for approximately 60 years. In connection with the sale of the coke plant, Honeywell agreed to indemnify AK Steel against certain claims and obligations that could arise from the investigation, and we intend to pursue such indemnification from Honeywell, if necessary. We cannot reasonably estimate how long it will take to complete the site investigation. On March 10, 2016, the EPA invited AK Steel to participate in settlement discussions regarding an enforcement action. Settlement discussions between the parties are ongoing, though whether the parties will reach agreement and any such agreement’s terms are uncertain. Until the site investigation is complete, we cannot reasonably estimate the costs, if any, we may incur for potential additional required remediation of the site or when we may incur them.

Burns Harbor Water Issues

In August 2019, ArcelorMittal Burns Harbor LLC (n/k/a Cleveland-Cliffs Burns Harbor LLC) suffered a loss of the blast furnace cooling water recycle system, which led to the discharge of cyanide and ammonia in excess of the Burns Harbor plant's NPDES permit limits. Since that time, the facility has taken numerous steps to prevent recurrence and maintain compliance with its NPDES permit. Since the August 2019 event, we have been engaged in settlement discussions with the U.S. Department of Justice, the EPA and the State of Indiana to resolve any alleged violations of environmental laws or regulations. Also, ArcelorMittal Burns Harbor LLC was served with a subpoena on December 5, 2019, from the United States District Court for the Northern District of Indiana relating to the August 2019 event and has responded to the subpoena requests. In addition, the plaintiffs in Environmental Law & Policy Center et al. v. ArcelorMittal Burns Harbor LLC et al. (U.S. District Court, N.D. Indiana Case No. 19-cv-473), which was filed on December 20, 2019, have alleged violations resulting from the August 2019 event and other Clean Water Act claims. Although we cannot accurately estimate the amount of civil penalty, the cost of any injunctive relief requirements, or the costs to resolve third-party claims, including potential natural resource damages claims, they are likely to exceed the reporting threshold in total.

In addition to the foregoing matters, we are or may be involved in proceedings with various regulatory authorities that may require us to pay fines, comply with more rigorous standards or other requirements or incur capital and operating expenses for environmental compliance. We believe that the ultimate disposition of any such proceedings will not have, individually or in the aggregate, a material adverse effect on our consolidated financial condition, results of operations or cash flows.

Tax Matters

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. We recognize liabilities for anticipated tax audit issues based on our estimate of whether, and the extent to which, additional taxes will be due. If we ultimately determine that payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary. We also recognize tax benefits to the extent that it is more likely than not that our positions will be sustained when challenged by the taxing authorities. To the extent we prevail in matters for which liabilities have been established, or are required to pay amounts in excess of our liabilities, our effective tax rate in a given period could be materially affected. An unfavorable tax settlement would require use of our cash and result in an increase in our effective tax rate in the year of resolution. A favorable tax settlement would be recognized as a reduction in our effective tax rate in the year of resolution. Refer to NOTE 12 - INCOME TAXES for further information.

Other Contingencies

In addition to the matters discussed above, there are various pending and potential claims against us and our subsidiaries involving product liability, commercial, employee benefits and other matters arising in the ordinary course of business. Because of the considerable uncertainties that exist for any claim, it is difficult to reliably or accurately estimate what the amount of a loss would be if a claimant prevails. If material assumptions or factual understandings we rely on to evaluate exposure for these contingencies prove to be inaccurate or otherwise change, we may be required to record a liability for an adverse outcome. If, however, we have reasonably evaluated potential future liabilities for all of these contingencies, including those described more specifically above, it is our opinion, unless we otherwise noted, that the ultimate liability from these contingencies, individually or in the aggregate, should not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Subsequent Events [Abstract]

SUBSEQUENT EVENTS

On February 11, 2021, we sold 20 million common shares, and the indirect, wholly owned subsidiary of ArcelorMittal to which approximately 78 million common shares were issued as part of the consideration paid by us in connection with the closing of the AM USA Transaction sold 40 million common shares, in each case at a price per share to the underwriter of $16.12, in an underwritten public offering. We also granted the underwriter an option to purchase up to an additional 9 million common shares from us at a price per share to the underwriter of $16.12. The underwriter has until March 10, 2021 to exercise such option, which it may do in full, in part or not at all. We did not receive any proceeds from the sale of the common shares by the selling shareholder in the offering. We intend to use the net proceeds to us from the offering, plus cash on hand, to redeem up to approximately $334 million aggregate principal amount of our outstanding 9.875% 2025 Senior Secured Notes. We intend to use any remaining net proceeds to us following such redemption to reduce borrowings under our ABL Facility.

On February 9, 2021, following pricing of the underwritten public offering, we issued a conditional notice of partial redemption to holders of the 9.875% 2025 Senior Secured Notes to redeem $322 million aggregate principal amount of the outstanding 9.875% 2025 Senior Secured Notes on March 11, 2021, at a redemption price equal to 109.875% of the principal amount to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. The conditional notice of partial redemption was subject to the condition precedent that we close the underwritten public offering of our common shares. As a result, following the closing of the underwritten public offering, the conditional notice of partial redemption became irrevocable.

On February 17, 2021, we issued $500 million aggregate principal amount of 4.625% 2029 Senior Notes and $500 million aggregate principal amount of 4.875% 2031 Senior Notes in an offering that was exempt from the registration requirements of the Securities Act. We intend to use the net proceeds from the notes offering to redeem all of the outstanding 4.875% 2024 Senior Secured Notes and 6.375% 2025 Senior Notes issued by Cleveland-Cliffs Inc. and all of the outstanding 7.625% 2021 AK Senior Notes, 7.50% 2023 AK Senior Notes and 6.375% 2025 AK Senior Notes issued by AK Steel Corporation (n/k/a Cleveland-Cliffs Steel Corporation), and pay fees and expenses in connection with such redemptions, and reduce borrowings under our ABL Facility.

On February 10, 2021, following pricing of the notes offering, we issued notices of redemption to the holders of the 4.875% 2024 Senior Secured Notes, 6.375% 2025 Senior Notes, 7.625% 2021 AK Senior Notes, 7.50% 2023

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2020

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Consolidation

Basis of Consolidation

The condensed consolidated financial statements consolidate our accounts and the accounts of our wholly owned subsidiaries, all subsidiaries in which we have a controlling interest and VIEs for which we are the primary beneficiary. All intercompany transactions and balances are eliminated upon consolidation.

Equity Method Investments

Investments in Affiliates

We have investments in several businesses accounted for using the equity method of accounting. These investments are included within our Steelmaking segment. We review an investment for impairment when circumstances indicate that a loss in value below its carrying amount is other than temporary. Investees and equity ownership percentages are presented below:

Investee	Equity Ownership Percentage
Combined Metals of Chicago, LLC	40.0%
Spartan Steel Coating, LLC	48.0%

As of December 31, 2019, our 23% ownership in Hibbing was recorded as an equity method investment. As a result of the acquisition of ArcelorMittal USA, we acquired an additional 62.3% ownership interest in Hibbing. As of December 31, 2020, our ownership in the Hibbing joint venture was 85.3% and was fully consolidated within our operating results with a noncontrolling interest.

We recorded a basis difference for Spartan Steel of $33 million as part of the AK Steel Merger. The basis difference relates to the excess of the fair value over the investee's carrying amount of property, plant and equipment and will be amortized over the remaining useful lives of the underlying assets.

As of December 31, 2020, our investment in affiliates of $105 million was classified in Other non-current assets. As of December 31, 2019, our investment in affiliates of $18 million was classified in Other non-current liabilities.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP 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 revenues and expenses during the reporting period. Our mineral reserves; future realizable cash flow; environmental, reclamation and closure obligations; valuation of business combinations, long-lived assets, inventory, tax assets and post-employment, post-retirement and other employee benefit liabilities; reserves for contingencies and litigation require the use of various management estimates and assumptions. Actual results could differ from estimates. Management reviews its estimates on an ongoing basis. Changes in facts and circumstances may alter such estimates and affect the results of operations and financial position in future periods.

Business Combinations Policy

Business Combinations

Assets acquired and liabilities assumed in a business combination are recognized and measured based on their estimated fair values at the acquisition date, while the acquisition-related costs are expensed as incurred. Any excess of the purchase consideration when compared to the fair value of the net tangible and intangible assets acquired, if any, is recorded as goodwill. We engaged independent valuation specialists to assist with the determination of the fair value of assets acquired, liabilities assumed, noncontrolling interest, and goodwill, for the Acquisitions. If the initial accounting for the business combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded. Subsequent to the acquisition date, and not later than one year from the acquisition date, we will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the date of the acquisition. Any adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period the adjustment arises.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and on deposit as well as all short-term securities held for the primary purpose of general liquidity. We consider investments in highly liquid debt instruments with an original maturity of three months or less from the date of acquisition and longer maturities when funds can be withdrawn in three months or less without a significant penalty to be cash equivalents. We routinely monitor and evaluate counterparty credit risk related to the financial institutions in which our short-term investment securities are held.

Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy

Trade Accounts Receivable and Allowance for Credit LossTrade accounts receivable are recorded at the point control transfers and represent the amount of consideration we expect to receive in exchange for transferred goods and do not bear interest. We establish provisions for expected lifetime losses on accounts receivable at the time a receivable is recorded based on historical experience, customer credit quality and forecasted economic conditions. We regularly review our accounts receivable balances and the allowance for credit loss and establish or adjust the allowance as necessary using the specific identification method in accordance with CECL. We evaluate the aggregation and risk characteristics of receivable pools and develop loss rates that reflect historical collections, current forecasts of future economic conditions over the time horizon we are exposed to credit risk, and payment terms or conditions that may materially affect future forecasts.

Inventories

Inventories

Inventories are generally stated at the lower of cost or net realizable value using average cost, excluding depreciation and amortization. Certain iron ore inventories are stated at the lower of cost or market using the LIFO method.

Refer to NOTE 2 - SUPPLEMENTARY FINANCIAL STATEMENT INFORMATION for further information.

Derivative Financial Instruments and Hedging Activities

Derivative Financial Instruments and Hedging Activities

We are exposed to certain risks related to the ongoing operations of our business, including those caused by changes in commodity prices and energy rates. We have established policies and procedures, including the use of certain derivative instruments, to manage such risks, if deemed necessary.

Derivative financial instruments are recognized as either assets or liabilities in the Statements of Consolidated Financial Position and measured at fair value. On the date a qualifying hedging instrument is executed, we designate the hedging instrument as a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge). We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific firm commitments or forecasted transactions. We also formally assess, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of the related hedged items. When it is determined that a derivative is not highly effective as a hedge, we discontinue hedge accounting prospectively and record all future changes in fair value in the period of the instrument's earnings or losses.

For derivative instruments that have been designated as cash flow hedges, the changes in fair value are recorded in Accumulated other comprehensive loss. Amounts recorded in Accumulated other comprehensive loss are

reclassified to earnings or losses in the period the underlying hedged transaction affects earnings or when the underlying hedged transaction is no longer reasonably possible of occurring.

For derivative instruments that have not been designated as cash flow hedges, such as provisional pricing arrangements, changes in fair value are recorded in the period of the instrument's earnings or losses.

Refer to Revenue Recognition below for discussion of derivatives recorded as a result of pricing terms in our sales contracts. Additionally, refer to NOTE 15 - DERIVATIVE INSTRUMENTS for further information.

Property, Plant and Equipment

Property, Plant and Equipment

Our properties are stated at the lower of cost less accumulated depreciation. Depreciation of plant and equipment is computed principally by the straight-line method based on estimated useful lives. Depreciation continues to be recognized when operations are idled temporarily. Depreciation and depletion are recorded over the following estimated useful lives:

Asset Class	Basis	Life
Land, land improvements and mineral rights
Land and mineral rights	Units of production	Life of mine
Land improvements	Straight line	20 to 45 years
Buildings	Straight line	20 to 45 years
Equipment	Straight line/Double declining balance	3 to 20 years

Refer to NOTE 6 - PROPERTY, PLANT AND EQUIPMENT for further information.

Goodwill and Other Intangible Assets and Liabilities

Goodwill

Goodwill represents the excess purchase price paid over the fair value of the net assets during an acquisition. Goodwill is not amortized, but is assessed for impairment on an annual basis on October 1 (or more frequently if necessary).

Other Intangible Assets and Liabilities

Intangible assets and liabilities are subject to periodic amortization on a straight-line basis over their estimated useful lives as follows:

Type	Basis	Useful Life
Intangible assets:
Customer relationships	Straight line	18 years
Developed technology	Straight line	17 years
Trade names and trademarks	Straight line	10 years
Mining permits	Straight line	Life of mine
Intangible liabilities:
Above-market supply contracts	Straight line	Contract term

Refer to NOTE 7 - GOODWILL AND INTANGIBLE ASSETS AND LIABILITIES for further information.

Leases

Leases

We determine if an arrangement contains a lease at inception. We recognize right-of-use assets and lease liabilities associated with leases based on the present value of the future minimum lease payments over the lease term at the commencement date. Lease terms reflect options to extend or terminate the lease when it is reasonably certain that the option will be exercised. For short-term leases (leases with an initial lease term of 12 months or less), right-of-use assets and lease liabilities are not recognized in the consolidated balance sheet, and lease expense is recognized on a straight-line basis over the lease term.

Refer to NOTE 13 - LEASE OBLIGATIONS for further information.

Asset Impairment

Asset Impairment

We monitor conditions that may affect the carrying value of our long-lived tangible and intangible assets when events and circumstances indicate that the carrying value of the asset groups may not be recoverable. In order to determine if assets have been impaired, assets are grouped and tested at the lowest level for which identifiable, independent cash flows are available ("asset group"). The measurement of the impairment loss to be recognized is based on the difference between the fair value and the carrying value of the asset group. Fair value can be determined using a market approach, income approach or cost approach.

For the years ended December 31, 2020, 2019 and 2018, no impairment indicators were present that would indicate the carrying value of any of our asset groups may not be recoverable; as a result, no impairment assessments were required.

Fair Value Measurements

Fair Value Measurements

ASC Topic 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for classification of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our own views about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized below:

•Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 — Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

•Level 3 — Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

The classification of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement in its entirety.

Refer to NOTE 9 - FAIR VALUE OF FINANCIAL INSTRUMENTS and NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Pension and Other Postretirement Plans

Pensions and Other Postretirement Benefits

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits as part of our total compensation and benefits programs.

We recognize the funded or unfunded status of our pension and OPEB obligations on our December 31, 2020 and 2019 Statements of Consolidated Financial Position based on the difference between the market value of plan assets and the actuarial present value of our retirement obligations on that date, on a plan-by-plan basis. If the plan assets exceed the pension and OPEB obligations, the amount of the surplus is recorded as an asset; if the pension and OPEB obligations exceed the plan assets, the amount of the underfunded obligations is recorded as a liability. Year-end balance sheet adjustments to pension and OPEB assets and obligations are recorded as Accumulated other comprehensive loss in the Statements of Consolidated Financial Position.

The actuarial estimates of the PBO and APBO incorporate various assumptions including the discount rates, the rates of increases in compensation, healthcare cost trend rates, mortality, retirement timing and employee turnover. The discount rate is determined based on the prevailing year-end rates for high-grade corporate bonds with a duration matching the expected cash flow timing of the benefit payments from the various plans. The remaining assumptions are based on our estimates of future events by incorporating historical trends and future expectations. The amount of net periodic cost that is recorded in the Statements of Consolidated Operations consists of several components including service cost, interest cost, expected return on plan assets, and amortization of previously unrecognized amounts. Service cost represents the value of the benefits earned in the current year by the participants. Interest cost represents the cost associated with the passage of time. Certain items, such as plan amendments, gains and/or losses resulting from differences between actual and assumed results for demographic

and economic factors affecting the obligations and assets of the plans, and changes in other assumptions are subject to deferred recognition for income and expense purposes. The expected return on plan assets is determined utilizing the weighted average of expected returns for plan asset investments in various asset categories based on historical performance, adjusted for current trends. Service costs are classified within Cost of goods sold, Selling, general and administrative expenses and Miscellaneous – net while the interest cost, expected return on assets, amortization of prior service costs/credits, net actuarial gain/loss, and other costs are classified within Other non-operating income.

Refer to NOTE 10 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Labor Agreements

Labor Agreements

At December 31, 2020, we employed approximately 25,000 people, of which approximately 18,500 were represented by labor unions under various agreements. We have agreements that will expire at five locations in 2021 and sixteen locations in 2022. Workers at some of our North American facilities are covered by agreements with the USW or other unions that have various expiration dates.

Asset Retirement Obligations

Asset Retirement Obligations

Asset retirement obligations are recognized when incurred and recorded as liabilities at fair value. The fair value of the liability is determined as the discounted value of the expected future cash flows. The asset retirement obligation is accreted over time through periodic charges to earnings. In addition, the asset retirement cost is capitalized and amortized over the life of the related asset. Reclamation costs are adjusted periodically to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. We review, on an annual basis, unless otherwise deemed necessary, the asset retirement obligation for each applicable operation in accordance with the provisions of ASC Topic 410, Asset Retirement and Environmental Obligations. We perform an in-depth evaluation of the liability every three years in addition to our routine annual assessments.

Future reclamation costs for inactive operations are accrued based on management’s best estimate at the end of each period of the costs expected to be incurred at a site. Such cost estimates include, where applicable, ongoing maintenance and monitoring costs. Changes in estimates at inactive operations are reflected in earnings in the period an estimate is revised.

Refer to NOTE 14 - ASSET RETIREMENT OBLIGATIONS for further information.

Environmental Remediation Costs

Environmental Remediation Costs

We have a formal policy for environmental protection and restoration. Certain of our operating activities are subject to various laws and regulations governing protection of the environment. We conduct our operations to protect the public health and environment and believe our operations are in compliance with applicable laws and regulations in all material respects. Our environmental liabilities, including obligations for known environmental remediation exposures, have been recognized based on the estimated cost of investigation and remediation at each site. If the cost can only be estimated as a range of possible amounts with no point in the range being more likely, the minimum of the range is accrued. Future expenditures are discounted unless the amount and timing of the cash disbursements cannot be reasonably estimated. It is possible that additional environmental obligations could be incurred, the extent of which cannot be assessed. Potential insurance recoveries have not been reflected in the determination of the liabilities.

Refer to NOTE 21 - COMMITMENTS AND CONTINGENCIES for further information.

Revenue Recognition

Revenue Recognition

Sales are recognized when our performance obligations are satisfied. Generally, our performance obligations are satisfied, control of our products is transferred and revenue is recognized at a single point in time, when title transfers to our customer for product shipped according to shipping terms. Shipping and other transportation costs charged to customers are treated as fulfillment activities and are recorded in both revenue and cost of sales at the time control is transferred to the customer. Refer to NOTE 4 - REVENUES for further information.

Repairs And Maintenance

Repairs and Maintenance

Repairs, maintenance and replacement of components are expensed as incurred. The cost of major equipment overhauls is capitalized and depreciated over the estimated useful life, which is the period until the next scheduled overhauls. All other planned and unplanned repairs and maintenance costs are expensed when incurred.

Share-based Compensation

Share-Based Compensation

The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. A correlation matrix of historical and projected stock prices was developed for both the Company and its predetermined peer group of mining and metals companies. The fair value assumes that the performance objective will be achieved. The expected term of the grant represents the time from the grant date to the end of the service period. We estimate the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds, with a term commensurate with the remaining performance period.

The fair value of the restricted stock units is determined based on the closing price of our common shares on the grant date.

Upon vesting of share-based compensation awards, we issue shares from treasury shares before issuing new shares. Forfeitures are recognized when they occur.

The fair value of stock options is estimated on the date of grant using a Black-Scholes model using the grant date price of our common shares and option exercise price, and assumptions regarding the option’s expected term, the volatility of our common shares, the risk-free interest rate, and the dividend yield over the option’s expected term.

Refer to NOTE 11 - STOCK COMPENSATION PLANS for additional information.

Income Taxes

Income Taxes

Income taxes are based on income for financial reporting purposes, calculated using tax rates by jurisdiction, and reflect a current tax liability or asset for the estimated taxes payable or recoverable on the current year tax return and expected annual changes in deferred taxes. Any interest or penalties on income tax are recognized as a component of Income tax benefit (expense).

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized within Net income (loss) in the period that includes the enactment date.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial results of operations.

Accounting for uncertainty in income taxes recognized in the financial statements requires that a tax benefit from an uncertain tax position be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on technical merits.

See NOTE 12 - INCOME TAXES for further information.

Discontinued Operations

Discontinued Operations

During 2018, we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and sold all of the assets of our Asia Pacific Iron Ore business through a series of sales to third parties. As a result of our exit, management determined that our Asia Pacific Iron Ore mining operations met the criteria to be classified as held for sale and a discontinued operation under ASC Topic 205, Presentation of Financial

Statements. As such, all current and historical Asia Pacific Iron Ore operating results are classified within discontinued operations.

Foreign Currency

Foreign Currency

Our financial statements are prepared with the U.S. dollar as the reporting currency and the functional currency of all subsidiaries is the U.S. dollar, except for our European Operations for which the functional currency is the Euro. In August 2018, management determined that there were significant changes in economic factors related to our Australian subsidiaries. The change in economic factors was a result of the sale and conveyance of substantially all assets and liabilities of our Australian subsidiaries to third parties, representing a significant change in operations. As such, the functional currency for the Australian subsidiaries changed from the Australian dollar to the U.S. dollar and all remaining Australian denominated monetary balances will be remeasured prospectively through the Statements of Consolidated Operations.

As a result of the liquidation of the Australian subsidiaries' assets, the historical impact of foreign currency translation recorded in Accumulated other comprehensive loss in the Statements of Consolidated Financial Position of $228 million was reclassified and recognized as a gain in Income (loss) from discontinued operations, net of tax in the Statements of Consolidated Operations for the year ended December 31, 2018.

Earnings Per Share

Earnings Per Share

We present both basic and diluted EPS amounts for continuing operations and discontinued operations. Total basic EPS amounts are calculated by dividing Net income (loss) attributable to Cliffs shareholders, less the earnings allocated to our Series B Participating Redeemable Preferred Stock, by the weighted average number of common shares outstanding during the period presented.

Total diluted EPS amounts are calculated by dividing Net income (loss) attributable to Cliffs shareholders by the weighted average number of common shares, common share equivalents under stock plans using the treasury-stock method, common share equivalents of the Series B Participating Redeemable Preferred Stock using the if-converted method and the calculated common share equivalents in excess of the conversion rate related to our 1.50% 2025 Convertible Senior Notes using the treasury-stock method. Common share equivalents are excluded from EPS computations in the periods in which they have an anti-dilutive effect.

See NOTE 8 - DEBT AND CREDIT FACILITIES and NOTE 20 - EARNINGS PER SHARE for further information.

Variable Interest Entities

Variable Interest Entities

We assess whether we have a variable interest in legal entities in which we have a financial relationship and, if so, whether or not those entities are VIEs. A VIE is an entity with insufficient equity at risk for the entity to finance its activities without additional subordinated financial support or in which equity investors lack the characteristics of a controlling financial interest. If an entity is determined to be a VIE, we evaluate whether we are the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. We conclude that we are the primary beneficiary and consolidate the VIE if we have both (i) the power to direct the activities of the VIE that most significantly influence the VIE's economic performance and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Refer to NOTE 19 - VARIABLE INTEREST ENTITIES for additional information.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Issued and Adopted

On March 2, 2020, the SEC issued a final rule that amended the disclosure requirements related to certain registered securities under SEC Regulation S-X, Rule 3-10, which required separate financial statements for subsidiary issuers and guarantors of registered debt securities unless certain exceptions are met. The final rule replaces the previous requirement under Rule 3-10 to provide condensed consolidating financial information in the registrant’s financial statements with a requirement to provide alternative financial disclosures (which include summarized financial information of the parent and any issuers and guarantors, as well as other qualitative disclosures) in either the registrant’s Management's Discussion and Analysis of Financial Condition and Results of Operations or its financial statements, in addition to other simplifications. The final rule is effective for filings on or after January 4, 2021, and early adoption is permitted. We elected to early adopt this disclosure update for the period ended March 31, 2020. As a result, we have excluded the footnote disclosures required under the previous Rule 3-10, and applied the final rule by including the summarized financial information and qualitative disclosures in Part II -

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of this Annual Report on Form 10-K and Exhibit 22, filed herewith.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except for short-term leases. For lessees, leases are classified as either operating or finance leases. We adopted this standard on its effective date of January 1, 2019 using the optional alternative approach, which requires application of the new guidance at the beginning of the standard's effective date. Adoption of the updated standard did not have a material effect on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which introduces a new accounting model, CECL. CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. CECL utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. We elected to early adopt this standard on December 31, 2019. Upon adoption, the updated standard did not have a material effect on our consolidated financial statements.

Issued and Not Effective

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). This update requires certain convertible instruments to be accounted for as a single liability measured at its amortized cost. Additionally, the update requires the use of the "if-converted" method, removing the treasury stock method, when calculating diluted shares. The two methods of adoption are the full and modified retrospective approaches. We expect to utilize the modified retrospective approach. Using this approach, the guidance shall be applied to transactions outstanding as of the beginning of the fiscal year in which the amendment is adopted. The final rule is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We are continuing to evaluate the impact of this update to our consolidated financial statements and would expect to adopt at the required adoption date of January 1, 2022.
