CSX CORPORATION
PART I
Item 1. Business
CSX Corporation, together with its subsidiaries ("CSX" or the “Company”), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based freight transportation services including traditional rail service, the transport of intermodal containers and trailers, as well as other transportation services such as rail-to-truck transfers and bulk commodity operations. CSX and the rail industry provide customers with access to an expansive and interconnected transportation network that plays a key role in North American commerce and is critical to the long-term economic success and improved global competitiveness of the United States. In addition, freight railroads provide the most economical and environmentally efficient means to transport goods over land.
CSX Transportation, Inc.
CSX’s principal operating subsidiary, CSX Transportation, Inc. (“CSXT”), provides an important link to the transportation supply chain through its approximately 19,500 route-mile rail network, which serves major population centers in 23 states east of the Mississippi River, the District of Columbia and the Canadian provinces of Ontario and Quebec. It has access to over 70 ocean, river and lake port terminals along the Atlantic and Gulf Coasts, the Mississippi River, the Great Lakes and the St. Lawrence Seaway. This access allows the Company to meet the dynamic transportation needs of manufacturers, industrial producers, the automotive industry, construction companies, farmers and feed mills, wholesalers and retailers, and energy producers. The Company’s intermodal business links customers to railroads via trucks and terminals. CSXT also serves thousands of production and distribution facilities through track connections with other Class I railroads and more than 230 short-line and regional railroads.
CSXT is also responsible for the Company's real estate sales, leasing, acquisition and management and development activities. Substantially all of these activities are focused on supporting railroad operations.
Other Entities
In addition to CSXT, the Company’s subsidiaries include Quality Carriers, Inc. ("Quality Carriers"), CSX Intermodal Terminals, Inc. (“CSX Intermodal Terminals”), Total Distribution Services, Inc. (“TDSI”), Transflo Terminal Services, Inc. (“Transflo”), CSX Technology, Inc. (“CSX Technology”) and other subsidiaries. Effective July 1, 2021, CSX acquired Quality Carriers, the largest provider of bulk liquid chemicals truck transportation in North America, from Quality Distribution, Inc. For further details, refer to Note 17, Business Combinations. CSX Intermodal Terminals owns and operates a system of intermodal terminals, predominantly in the eastern United States, and also provides drayage services (the pickup and delivery of intermodal shipments) for certain customers. TDSI serves the automotive industry with distribution centers and storage locations. Transflo connects non-rail served customers to the many benefits of rail by transferring products from rail to trucks. The biggest Transflo markets are chemicals and agriculture, which includes shipments of plastics and ethanol. CSX Technology and other subsidiaries provide support services for the Company.
Operating Model
The Company is focused on developing and strictly maintaining a scheduled service plan with an emphasis on optimizing assets. When this operating model is executed effectively, customer service is improved, enabling the Company to better compete for an increased share of the U.S. freight market. Further, this model leads to reduced costs and strong free cash flow generation.

CSX CORPORATION
PART I
Lines of Business
During 2021, the Company's services generated $12.5 billion of revenue and served four primary lines of business: merchandise, intermodal, coal and trucking.
•The merchandise business shipped 2.6 million carloads (41% of volume) and generated 60% of revenue in 2021. The Company’s merchandise business is comprised of shipments in the following diverse markets: chemicals, agricultural and food products, minerals, automotive, forest products, metals and equipment, and fertilizers.
•The intermodal business shipped 3.0 million units (48% of volume) and generated 16% of revenue in 2021. The intermodal business combines the superior economics of rail transportation with the flexibility of trucks and offers a cost and environmental advantage over long-haul trucking. Through a network of approximately 30 terminals, the intermodal business serves all major markets east of the Mississippi River and transports mainly manufactured consumer goods in containers, providing customers with truck-like service for longer shipments.
•The coal business shipped 706 thousand carloads (11% of volume) and generated 14% of revenue in 2021. The Company transports domestic coal, coke and iron ore to electricity-generating power plants, steel manufacturers and industrial plants as well as export coal to deep-water port facilities. Approximately one-quarter of export coal and the majority of the domestic coal that the Company transports is used for generating electricity or industrial purposes.
•The trucking business generated 3% of revenue in 2021. Trucking revenue includes revenue from the operations of Quality Carriers, which was acquired by CSX effective July 1, 2021.
Other revenue accounted for 7% of the Company’s total revenue in 2021. This category includes revenue from regional subsidiary railroads and incidental charges, including intermodal storage and equipment usage, demurrage and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.
CSX's Committed Workforce
Most of the Company’s employees provide or support transportation services. The Company had more than 20,900 employees as of December 2021, which includes approximately 16,500 employees that are members of a labor union. For the 13 rail unions that participate in national bargaining, a round of negotiations for benefits, wages and work rules is underway. Typically, these negotiations take several years. Current agreements remain in place until modified by new agreements.
CSX prioritizes workplace safety for employees and is committed to continued improvement through enhanced processes, training, technology, communication, and continuous collaboration with customers and peers across the railroad industry. Training programs and processes are focused on injury and accident prevention as well as emergency preparedness. The attainment of key safety targets is a component of management's annual incentive program. The FRA Personal Injury Frequency Index, a measure of the number of FRA-reportable injuries per 200,000 man-hours, was 0.92 in 2021 and 0.82 in 2020, representing a 12% increase year over year.

CSX CORPORATION
PART I
In response to the novel coronavirus ("COVID-19") pandemic, additional policies and procedures were developed to protect the health and safety of employees. A cross-functional task force continues to monitor the situation to ensure that appropriate safety measures are being taken.
The Compensation and Talent Management Committee of the Board of Directors is charged with oversight of CSX's workforce. The Company is committed to developing a culture that promotes workforce diversity and inclusion and encourages ethical behavior. As of December 31, 2021, approximately 20% of CSX's overall workforce and 37% of management was diverse, calculated as the percentage of males of color and all females. In 2021, CSX was recognized as a “Best Place to Work for Disability Inclusion” by Disability:IN and the American Association of People with Disabilities for a third consecutive year after receiving a top score on their disability equality index. The CSX Code of Ethics serves as a guiding standard for ethical behavior and covers many types of matters, including discrimination and harassment as well as safety. Annually, all management employees are required, and union employees are highly encouraged, to complete ethics training.
Company History
A leader in freight rail transportation for more than 190 years, the Company’s heritage dates back to the early nineteenth century when The Baltimore and Ohio Railroad Company (“B&O”), the nation’s first common carrier, was chartered in 1827. Since that time, the Company has built on this foundation to create a railroad that could safely and reliably service the ever-increasing demands of a growing nation. Since its founding, numerous railroads have combined with the former B&O through merger and consolidation to create what has become CSX. Each of the railroads that combined into the CSX family brought new geographical reach to valuable markets, gateways, cities, ports and transportation corridors.
CSX Corporation was incorporated in 1978 under Virginia law. In 1980, the Company completed the merger of the Chessie System and Seaboard Coast Line Industries into CSX. The merger allowed the Company to connect northern population centers and Appalachian coal fields to growing southeastern markets. Later, the Company’s acquisition of key portions of Conrail, Inc. ("Conrail") allowed CSXT to link the northeast, including New England and the New York metropolitan area, with Chicago and midwestern markets as well as the growing areas in the Southeast already served by CSXT. This current rail network allows the Company to directly serve every major market in the eastern United States with safe, dependable, environmentally responsible and fuel efficient freight transportation and intermodal service.
Competition
The business environment in which the Company operates is highly competitive. Shippers typically select transportation providers that offer the most compelling combination of service and price. Service requirements, both in terms of transit time and reliability, vary by shipper and commodity. As a result, the Company’s primary competition varies by commodity, geographic location and mode of available transportation and includes other railroads, motor carriers that operate similar routes across its service area and, to a less significant extent, barges, ships and pipelines.
CSXT’s primary rail competitor is Norfolk Southern Railway, which operates throughout much of the Company’s territory. Other railroads also operate in parts of the Company’s territory. Depending on the specific market, competing railroads and deregulated motor carriers may exert pressure on price and service levels. For further discussion on the risk of competition to the Company, see Item 1A. Risk Factors.

CSX CORPORATION
PART I
Regulatory Environment
The Company's operations are subject to various federal, state, provincial (Canada) and local laws and regulations generally applicable to businesses operating in the United States and Canada. In the U.S., the railroad operations conducted by the Company's subsidiaries, including CSXT, are subject to the regulatory jurisdiction of the Surface Transportation Board (“STB”), the Federal Railroad Administration (“FRA”), and its sister agency within the U.S. Department of Transportation ("DOT"), the Pipeline and Hazardous Materials Safety Administration (“PHMSA”). Together, FRA and PHMSA have broad jurisdiction over railroad operating standards and practices, including track, freight cars, locomotives and hazardous materials requirements. In addition, the U.S. Environmental Protection Agency (“EPA”) has regulatory authority with respect to matters that impact the Company's properties and operations.
The Transportation Security Administration (“TSA”), a component of the Department of Homeland Security, has broad authority over railroad operating practices that may have homeland security implications. In Canada, the railroad operations conducted by the Company’s subsidiaries, including CSXT, are subject to the regulatory jurisdiction of the Canadian Transportation Agency.
Although the Staggers Act of 1980 significantly deregulated the U.S. rail industry, the STB has broad jurisdiction over rail carriers. The STB regulates routes, fuel surcharges, conditions of service, rates for non-exempt traffic, acquisitions of control over rail common carriers and the transfer, extension or abandonment of rail lines, among other railroad activities. Any new rules from the STB regarding, among other things, competitive access or revenue adequacy could have a material adverse effect on the Company's financial condition, results of operations and liquidity as well as its ability to invest in enhancing and maintaining vital infrastructure. For further discussion on regulatory risks to the Company, see Item 1A. Risk Factors.
Financial Information
Information regarding the Company's results of operations and financial position can be found in Item 7. Management’s Discussion and Analysis of Financial Condition.

Legislation passed by Congress, new regulations issued by federal agencies or executive orders issued by the President of the United States could significantly affect the revenues, costs, including income taxes, and profitability of the Company's business. In addition, statutes or regulations imposing price constraints or affecting rail-to-rail competition could adversely affect the Company's profitability.
Government regulation and compliance risks may adversely affect the Company's operations and financial results.
The Company is subject to the jurisdiction of various regulatory agencies, including the STB, FRA, PHMSA, TSA, EPA and other state, provincial and federal regulatory agencies for a variety of economic, health, safety, labor, environmental, tax, legal and other matters. New or modified rules or regulations by these agencies could increase the Company's operating costs, adversely impact revenue or reduce operating efficiencies and affect service performance. Noncompliance with applicable laws or regulations could erode public confidence in the Company and can subject the Company to fines, penalties and other legal or regulatory sanctions.
CSXT, as a common carrier by rail, is required by law to transport hazardous materials, which could expose the Company to significant costs and claims.
A train accident involving the transport of hazardous materials could result in significant claims arising from personal injury, property or natural resource damage, environmental penalties and remediation obligations. Such claims, if insured, could exceed existing insurance coverage or insurance may not continue to be available at commercially reasonable rates. Under federal regulations, CSXT is required to transport hazardous materials under the legal duty referred to as the common carrier mandate.
CSXT is also required to comply with regulations regarding the handling of hazardous materials. In November 2008, the TSA issued final rules placing significant new security and safety requirements on passenger and freight railroad carriers, rail transit systems and facilities that ship hazardous materials by rail. Noncompliance with these rules can subject the Company to significant penalties and could be a factor in litigation arising out of a train accident. Finally, legislation preventing the transport of hazardous materials through certain cities could result in network congestion and increase the length of haul for hazardous substances, which could increase operating costs, reduce operating efficiency or increase the risk of an accident involving the transport of hazardous materials.

CSX CORPORATION
PART I
The Company may be subject to various claims and lawsuits that could result in significant expenditures.
As part of its railroad and other operations, the Company is subject to various claims and lawsuits related to disputes over commercial practices, labor and unemployment matters, occupational and personal injury claims, property damage, environmental and other matters. The Company may experience material judgments or incur significant costs to defend existing and future lawsuits. Although the Company maintains insurance to cover some of these types of claims and establishes reserves when appropriate, final amounts determined to be due on any outstanding matters may exceed the Company's insurance coverage or differ materially from the recorded reserves. Additionally, the Company could be impacted by adverse developments not currently reflected in the Company's reserve estimates.
Operational, Safety and Business Disruption
An epidemic or pandemic, including the ongoing COVID-19 pandemic, and the initiatives to reduce its transmission could adversely affect the Company's business.
The Company could be materially and adversely affected by a public health crisis, including a widespread epidemic or pandemic. As COVID-19 and its variant strains have spread globally, including significant impacts in the United States, CSX continues to take a variety of measures to ensure the availability of its transportation services, promote the safety and security of its employees and support the communities in which it operates. However, public and private sector policies and initiatives to reduce the transmission of COVID-19, such as closures of businesses and manufacturing facilities, the promotion of social distancing, the adoption of working from home by companies and institutions, and travel restrictions could continue to adversely affect demand for the commodities and products that the Company transports, including import and export volume.
In addition, COVID-19 and the related initiatives to reduce transmission have resulted in greater supply chain disruption, which could continue to impact volumes and make it more difficult for the Company to serve its customers. The extent to which COVID-19 continues to impact operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, its effects on demand for the Company’s transportation services and the supply chain, as well as the effect of governmental regulations imposed in response to the pandemic. The duration of the pandemic is dependent on several factors, including the impacts of virus variants and case resurgences across the country. Moreover, operations are negatively affected when a significant number of employees are quarantined as the result of exposure to a contagious illness. To the extent COVID-19 adversely affects the Company's business and financial results, it may also have the effect of heightening many of the other risks described herein.
The Company relies on the security, stability and availability of its technology systems to operate its business.
The Company relies on information technology in all aspects of its business. The security, stability and availability of the Company’s and its key third-party vendors’ technology systems are critical to its ability to operate safely and effectively and to compete within the transportation industry. A successful data breach, cyber-attack, or the occurrence of any similar incident that impacts the Company’s or its key third-party vendors’ information technology systems could result in a service interruption, train accident, misappropriation of confidential or proprietary information (including personal information), process failure, or other operational difficulties. A disruption or compromise of the Company’s information technology systems, even for short periods of time, and any resulting theft or compromise of Company confidential or proprietary information (including personal information), could adversely affect the Company’s business or reputation, create significant legal, regulatory or financial exposure and have a material adverse impact on CSX’s business, financial condition or operations.
CSX 2021 Form 10-K p.8

CSX CORPORATION
PART I
The Company, its third-party vendors and other companies in the rail and transportation industries have been subject to, and are likely to continue to be the target of, data breaches, cyber-attacks and other similar incidents. These incidents may include, among other things, malware, ransomware, distributed denial of service attacks, social engineering, phishing, theft, malfeasance or improper access by employees or third-party vendors, human error, fraud, or other modes of attack or disruption. Attacks of these nature are increasing in frequency, levels of persistence, intensity and sophistication. Further, the Company may be at increased risk of a cyber-attack as a result of being a component of the critical U.S. infrastructure. As cybersecurity threats continue to evolve, the Company may be required to expend significant additional resources to continue to modify or enhance its protective measures or to investigate and remediate any information security vulnerabilities, data breaches, cyber-attacks or other similar incidents. The ongoing COVID-19 pandemic also increases the risk that the Company or its third-party vendors may experience cybersecurity incidents as a result of employees, third-party vendors and other third parties with which they interact working remotely on less secure systems and environments.
Despite the Company’s efforts to protect its information technology systems, it may not be able to prevent or anticipate all data breaches, cyber-attacks or other similar incidents, detect or react to such incidents in a timely manner or adequately remediate any such incident. While CSX’s security protocols have detected attempts to gain unauthorized access to the Company’s information technology systems, none of such attempts have resulted in any material breach of or disruption to the Company’s systems. For example, CSX has experienced distributed denial of service attacks that have resulted in brief system disruptions, but none have resulted in access to CSX systems. Additionally, despite routine security assessment of the Company’s key third-party vendors, some vendors have experienced cyber-attacks in the past, but none of such attacks have had a material adverse impact on CSX’s business or operations. Due to applicable laws and regulations or contractual obligations, CSX may be held responsible for data breaches, cyber-attacks or other similar incidents attributed to its third-party vendors as they relate to the information CSX shares with them.
Network or supply chain constraints could have a negative impact on service, operating efficiency or volume of shipments.
CSXT could experience rail network difficulties related to: (i) unpredictable increases in demand; (ii) locomotive or crew shortages; (iii) labor shortages or other service disruptions in the supply chain affecting trucking, ports, handling facilities, customer facilities or other railroads; (iv) reductions in availability of pooled equipment, including chassis; (v) extreme weather conditions; (vi) impacts from changes in yard capacity, or network structure or composition, including train routes; (vii) increased passenger activities; or (viii) regulatory changes resulting in forced access or impacting where and how fast CSXT can transport freight or maintain routes, which could impact CSXT's operational fluidity, leading to deterioration of service, asset utilization and overall efficiency.
Future acts of terrorism, war or regulatory changes to combat the risk of terrorism may cause significant disruptions in the Company's operations.
Terrorist attacks, along with any government response to those attacks, may adversely affect the Company's financial condition, results of operations or liquidity. CSXT's rail lines, other key infrastructure and information technology systems may be targets or indirect casualties of acts of terror or war. This risk could cause significant business interruption and result in increased costs and liabilities and decreased revenues. In addition, premiums charged for some or all of the insurance coverage currently maintained by the Company could increase dramatically, or the coverage may no longer be available.
CSX 2021 Form 10-K p.9

CSX CORPORATION
PART I
Furthermore, in response to the heightened risk of terrorism, federal, state and local governmental bodies are proposing and, in some cases, have adopted legislation and regulations relating to security issues that impact the transportation industry. For example, the Department of Homeland Security adopted regulations that require freight railroads to implement additional security protocols when transporting hazardous materials. Complying with these or future regulations could continue to increase the Company's operating costs and reduce operating efficiencies.
Severe weather or other natural occurrences could result in significant business interruptions and expenditures in excess of available insurance coverage.
The Company's operations may be affected by external factors such as severe weather and other natural occurrences, including floods, fires, hurricanes and earthquakes. As a result, the Company's rail network may be damaged, its workforce may be unavailable, fuel costs may rise and significant business interruptions could occur. In addition, the performance of locomotives and railcars could be adversely affected by extreme weather conditions. Insurance maintained by the Company to protect against loss of business and other related consequences resulting from these natural occurrences is subject to coverage limitations, depending on the nature of the risk insured. This insurance may not be sufficient to cover all of the Company's damages or damages to others, and this insurance may not continue to be available at commercially reasonable rates. Even with insurance, if any natural occurrence leads to a catastrophic interruption of service, the Company may not be able to restore service without a significant interruption in operations.
Competitive, Economic and Financial
The Company faces competition from other transportation providers.
The Company experiences competition in pricing, service, reliability and other factors from various transportation providers including railroads and motor carriers that operate similar routes across its service area and, to a less significant extent, barges, ships and pipelines. Other transportation providers generally use public rights-of-way that are built and maintained by governmental entities, while CSXT and other railroads must build and maintain rail networks largely using internal resources. Any future improvements or expenditures materially increasing the quality or reducing the cost of alternative modes of transportation such as through the use of automation, autonomy or electrification, or legislation providing for less stringent size or weight restrictions on trucks, could negatively impact the Company's competitive position. Additionally, any future consolidation in the rail industry could materially affect the regulatory and competitive environment in which the Company operates.
Global economic conditions could negatively affect demand for commodities and other freight.
A decline or disruption in general domestic and global economic conditions that affects demand for the commodities and products the Company transports, including import and export volume, could reduce revenues or have other adverse effects on the Company's cost structure and profitability. For example, slower rates of economic growth in Asia, contraction of European economies, and changes in the global supply of seaborne coal or price of seaborne coal have adverse impacts on U.S. export coal volume and result in lower coal revenue for CSX. Additionally, changes to trade agreements or policies could result in reduced import and export volumes due to increased tariffs and lower consumer demand. If the Company experiences significant declines in demand for its transportation services with respect to one or more commodities and products, the Company may experience reduced revenue and increased operating costs, workforce adjustments, and other related activities, which could have a material adverse effect on the Company's financial condition, results of operations and liquidity.
CSX 2021 Form 10-K p.10

CSX CORPORATION
PART I
Changing dynamics in the U.S. and global energy markets could negatively impact profitability.
Over time, changing dynamics in the U.S. and global energy markets have resulted in lower energy production from coal-fired power plants in CSX's service territory. Changes in natural gas prices, or other factors impacting demand for electricity, could impact future power generation at coal-fired plants, which would affect the Company's domestic coal volumes and revenues.
Weaknesses in the capital and credit markets could negatively impact the Company’s access to capital.
The Company regularly relies on capital markets for the issuance of long-term debt instruments, commercial paper and bank financing from time to time. Instability or disruptions of the capital markets, including credit markets, or the deterioration of the Company’s financial condition due to internal or external factors, could restrict or prohibit access and could increase financing costs. A significant deterioration of the Company’s financial condition could also reduce credit ratings and could limit or affect its access to external sources of capital and increase the costs of short and long-term debt financing.
Availability of Critical Supplies and Labor
The unavailability of critical resources could adversely affect the Company’s operational efficiency and ability to meet demand.
Marketplace conditions for resources like locomotives as well as the availability of qualified personnel, particularly engineers and conductors, could each have a negative impact on the Company’s ability to meet demand for rail service. Although the Company strives to maintain adequate resources and personnel for the current business environment, unpredictable increases in demand for rail services or extreme weather conditions may exacerbate such risks, which could have a negative impact on the Company’s operational efficiency and otherwise have a material adverse effect on the Company’s financial condition, results of operations, or liquidity in a particular period.
Disruption to a key railroad industry supplier could negatively affect operating efficiency and increase costs.
The capital intensive and unique nature of core rail equipment (including rail, ties, rolling stock equipment and locomotives) limits the number of railroad equipment suppliers. If any of the current manufacturers stops production or experiences a supply shortage, CSXT could experience a significant cost increase or material shortage. In addition, a few critical railroad suppliers are foreign and, as such, adverse developments in international relations, new trade regulations, disruptions in international shipping or increases in global demand could make procurement of these supplies more difficult or increase CSXT's costs. Additionally, if a fuel supply shortage were to arise, the Company would be negatively impacted.
Failure to complete negotiations on collective bargaining agreements could result in strikes and/or work stoppages.
Most of CSX's employees are represented by labor unions and are covered by collective bargaining agreements. These agreements are either bargained for nationally by the National Carriers Conference Committee or locally between CSX and the union. Such agreements are negotiated over the course of several years and previously have not resulted in any extended work stoppages. Under the Railway Labor Act's procedures (which include mediation, cooling-off periods and the possibility of an intervention by the President of the United States), during negotiations neither party may take action until the procedures are exhausted. If, however, CSX is unable to negotiate acceptable agreements, the employees covered by the Railway Labor Act could strike, which could result in loss of business and increased operating costs as a result of higher wages or benefits paid to union members.

PART I
Climate Change and Environmental
The Company’s operations and financial results could be negatively impacted by climate change and regulatory and legislative responses to climate change.
There is potential for operational impacts from changing weather patterns or rising sea levels in the Company's operational territory, which could impact the Company's network or other assets. Climate change and other emissions-related laws and regulations have been proposed and, in some cases adopted, on the federal, state, provincial and local levels. These final and proposed laws and regulations take the form of restrictions, caps, taxes or other controls on emissions. In particular, the EPA has issued various regulations and may issue additional regulations targeting emissions, including rules and standards governing emissions from certain stationary sources and from vehicles.
Any of these pending or proposed laws or regulations, including any proposed or implemented under the Biden administration, could adversely affect the Company's operations and financial results by, among other things: (i) reducing coal-fired electricity generation due to mandated emission standards; (ii) reducing the consumption of coal as a viable energy resource in the United States and Canada; (iii) increasing the Company's fuel, capital and other operating costs and negatively affecting operating and fuel efficiencies; and (iv) making it difficult for the Company's customers in the U.S. and Canada to produce products in a cost competitive manner. Any of these factors could reduce the amount of shipments the Company handles and have a material adverse effect on the Company's financial condition, results of operations or liquidity.
The Company is subject to environmental laws and regulations that may result in significant costs.
The Company is subject to wide-ranging federal, state, provincial and local environmental laws and regulations concerning, among other things, emissions into the air, ground and water; the handling, storage, use, generation, transportation and disposal of waste and other materials; the clean-up of hazardous material and petroleum releases and the health and safety of our employees. If the Company violates or fails to comply with these laws and regulations, CSX could be fined or otherwise sanctioned by regulators. The Company can also be held liable for consequences arising out of human exposure to any hazardous substances for which CSX is responsible. In certain circumstances, environmental liability can extend to formerly owned or operated properties, leased properties, adjacent properties and properties owned by third parties or Company predecessors, as well as to properties currently owned, leased or used by the Company.
The Company has been, and may in the future be, subject to allegations or findings to the effect that it has violated, or is strictly liable under, environmental laws or regulations, and such violations can result in the Company's incurring fines, penalties or costs relating to the cleanup of environmental contamination. Although the Company believes it has appropriately recorded current and long-term liabilities for known and reasonably estimable future environmental costs, it could incur significant costs that exceed reserves or require unanticipated cash expenditures as a result of any of the foregoing. The Company also may be required to incur significant expenses to investigate and remediate known, unknown or future environmental contamination.

Item 2. Properties
The Company’s properties primarily consist of track and its related infrastructure, locomotives and freight cars and equipment. These categories and the geography of the network are described below.
Track and Infrastructure
Serving 23 states, the District of Columbia, and the Canadian provinces of Ontario and Quebec, the CSXT rail network serves, among other markets, New York, Philadelphia and Boston in the Northeast and Mid-Atlantic, the southeast markets of Atlanta, Miami and New Orleans, and the midwestern markets of St. Louis, Memphis and Chicago.
CSXT’s track structure includes mainline track, connecting terminals and yards, track within terminals and switching yards, sidings used for passing trains, track connecting CSXT's track to customer locations and turnouts that divert trains from one track to another. Total track miles, which reflect the size of CSXT’s network that connects markets, customers and western railroads, are greater than CSXT’s approximately 19,500 route miles. At December 2021, the breakdown of track miles was as follows:

| Track
| Miles
Single mainline track | 19,433 |
Other mainline track | 5,707 |
Terminals and switching yards | 9,278 |
Passing sidings and turnouts | 887 |
Total | 35,305 |

In addition to its physical track structure, the Company operates numerous yards and terminals for rail and intermodal service. These serve as points of connectivity between the Company and its local customers and as sorting facilities where railcars and intermodal containers are received, classed for destination and placed onto outbound trains, or arrive and are delivered to the customer. The Company’s largest yards and terminals based on 2021 volume (number of railcars or intermodal containers processed) are listed below.

Yards and Terminals | Annual Volume
Waycross, GA | 930,621 |
Bedford Park Intermodal Terminal (Chicago) | 916,805 |

Network Geography
CSXT’s operations are primarily focused on four major transportation networks and corridors that are defined geographically and by commodity flows below.
Interstate 90 (I-90) Corridor – This CSXT corridor links Chicago and the Midwest to metropolitan areas in New York and New England. This route, also known as the “waterlevel route,” has minimal hills and grades and nearly all of it has two main tracks (referred to as double track). These engineering attributes permit the corridor to support high-speed service across intermodal, automotive and merchandise commodities. This corridor is a primary route for import traffic coming from the far east through western ports moving eastward across the country, through Chicago and into the population centers in the Northeast. The I-90 Corridor is also a critical link between ports in New York, New Jersey, and Pennsylvania and consumption markets in the Midwest. This route carries goods from all three of the Company’s major markets – merchandise, intermodal and coal.
Interstate 95 (I-95) Corridor – The CSXT I-95 Corridor connects Charleston, Jacksonville, Miami and many other cities throughout the Southeast with the heavily populated mid-Atlantic and northeastern cities of Baltimore, Philadelphia and New York. CSXT primarily transports food and consumer products, as well as metals and chemicals along this line. It is the leading rail corridor along the eastern seaboard south of the District of Columbia and provides access to major eastern ports.
Southeastern Corridor – This critical part of the network runs between CSXT’s western gateways of Chicago, St. Louis and Memphis through the cities of Nashville, Birmingham, and Atlanta and markets in the Southeast. The Southeastern Corridor is the premier rail route connecting these key cities, gateways, and markets and positions CSXT to efficiently handle projected traffic volumes of intermodal, automotive and general merchandise traffic. The corridor also provides direct rail service between the coal reserves of the southern Illinois basin and the demand for coal in the Southeast.
Coal Network – The CSXT coal network connects the coal mining operations in the Appalachian mountain region and Illinois basin with industrial areas in the Southeast, Northeast and Mid-Atlantic, as well as many river, lake, and deep water port facilities. The domestic coal market has declined significantly over the last decade and export coal remains subject to a high degree of volatility. CSXT’s coal network remains well positioned to supply utility markets in both the Northeast and Southeast and to transport coal shipments for export outside of the U.S. Approximately one-quarter of export coal and the majority of the domestic coal that the Company transports is used for generating electricity or industrial purposes.
See the following page for a map of the CSX Rail Network. Also included on the map, "CSX Operating Agreement" indicates areas within which CSX can operate through trackage rights beyond the CSX network.

Locomotives
As of December 2021, CSXT owns or long-term leases more than 3,500 locomotives. From time to time, the Company also short-term leases locomotives based on business needs. Freight locomotives are used primarily to pull trains while switching locomotives are used in yards. Auxiliary units are typically used to provide extra traction for heavy trains in hilly terrain. Of owned locomotives, approximately 68% were in active service as of December 31, 2021, and the remainder were in storage to be utilized as needed. Storing locomotives and equipment allows the Company to quickly adjust its active fleet based on demand and other factors while avoiding delays due to supply limitations or excessive lead times to acquire additional equipment. As of December 2021, CSXT’s fleet of owned or long-term leased locomotives consisted of the following types:

| Locomotives |  | % |  | Average Age (years)
Freight | 3,126 |  |  | 89 | % |  | 22 |
Switching | 212 |  |  | 6 | % |  | 43 |
Auxiliary units | 178 |  |  | 5 | % |  | 29 |
Total locomotives | 3,516 |  |  | 100 | % |  | 22 |

Equipment
The Company owns or long-term leases rail equipment, including several types of freight cars and intermodal containers. Of total owned and long-term leased equipment, approximately 87% was in active service as of December 31, 2021, and the remainder were in storage to be utilized as needed. As of December 2021, the Company’s owned and long-term leased equipment consisted of the following:

Equipment | Number of Units |  | %
Gondolas | 18,394 |  |  | 38 | %
Multi-level flat cars | 10,910 |  |  | 23 | %
Covered hoppers | 7,187 |  |  | 15 | %
Open-top hoppers | 6,610 |  |  | 14 | %
Box cars | 3,926 |  |  | 8 | %
Flat cars | 622 |  |  | 1 | %
Other cars | 384 |  |  | 1 | %
Subtotal freight cars | 48,033 |  |  | 100 | %
Containers | 17,147 |  |  |
Total equipment | 65,180 |  |  |

At any time, approximately two-thirds of the railcars on the CSXT system are not owned or leased by the Company. Examples of these include railcars owned by other railroads (which are utilized by CSXT), shipper-furnished or private cars (which are generally used only in that shipper’s service), multi-level railcars used to transport automobiles (which are shared between railroads) and double-stack railcars, or well cars (which are industry pooled), that allow for two intermodal containers to be loaded one above the other.

Acquisition of Quality Carriers, Inc.
On July 1, 2021, CSX acquired Quality Carriers, Inc. from Quality Distribution, Inc. for a purchase price of $544 million in cash, which is presented on the statement of cash flows net of $3 million cash acquired. This transaction was funded by cash on hand. For further details, refer to Note 17, Business Combinations.
COVID-19 Update
Demand for rail services has improved from steep declines in the first half of 2020, but the effects of the disruption of global manufacturing, supply chains and consumer spending as a result of the COVID-19 global pandemic are ongoing. Future impacts of the pandemic on the Company’s financial and operating results will be determined by its duration, effects on the demand for the Company’s transportation services and the supply chain, as well as the effect of governmental regulations imposed and legislative stimulus packages passed in response to the pandemic. The duration of the pandemic is dependent on several factors, including the impacts of virus mutations and case resurgences across the country.
CSX employees that provide efficient and reliable rail service are essential to keeping supply chains fluid in response to this challenge. Accordingly, business operations have been modified to ensure the safety of employees across the network while continuing to provide a high level of service to customers. The Company is strongly encouraging employees to get vaccinated. A cross-functional task force continues to monitor and coordinate the Company’s response to COVID-19.

PART II
Revenue
Total revenue increased $1.9 billion in 2021, or 18%, when compared to the previous year due to higher volume, the inclusion of Quality Carriers' results, pricing gains, increases in other revenue and higher fuel recovery.
Merchandise Volume
Chemicals - Decreased due to lower shipments of crude oil and other energy-related commodities, partially offset by higher shipments of core chemicals and waste.
Agricultural and Food Products - Increased as a result of higher shipments of vegetable oils, ethanol, and food and consumer products.
Minerals - Increased as a result of higher shipments of cement, lime and limestone.
Automotive - Decreased due to lower vehicle production at plants served by CSX, which were impacted by shortages of semiconductors and other parts.
Forest Products - Increased primarily due to higher shipments of pulpboard, woodpulp and building products.
Metals and Equipment - Increased as growth across the metals markets was partially offset by reduced equipment shipments.
Fertilizers - Increased due to higher long-haul fertilizer shipments, partially offset by lower short-haul phosphate shipments.
Intermodal Volume
Increases in both domestic and international shipments resulted from strong demand, tight truck capacity, inventory replenishments and growth in rail volumes from east coast ports.
Coal Volume
The increase in export coal was driven by higher international shipments of both thermal coal and metallurgical coal. Domestic coal increased due to higher shipments of utility coal as well as higher steel and industrial shipments.
Trucking Revenue
Trucking revenue increased $410 million versus prior year due to the inclusion of Quality Carriers' results.
Other
Other revenue increased $336 million versus prior year due to increases in revenue for intermodal storage and equipment usage as well as higher affiliate and demurrage revenue.

PART II
Expense
In 2021, total expenses increased $707 million, or 11%, compared to prior year. Descriptions of each expense category as well as significant year-over-year changes are described below.
Labor and Fringe expenses include employee wages and related payroll taxes, health and welfare costs, pension, other post-retirement benefits and incentive compensation. These expenses increased $275 million due to the following items:
•Inflation and higher volume resulted in $133 million of increased expenses.
•Incentive compensation increased $123 million primarily due to higher expected payouts in the current year, including accelerated expense for certain employees.
•The acquisition of Quality Carriers resulted in increased costs of $61 million.
•Other costs decreased $42 million primarily due to efficiency savings, lower severance expenses and other non-significant items, partially offset by expenses related to increased hiring and new retention programs of $38 million.
Purchased Services and Other expenses consist primarily of contracted services to maintain infrastructure and equipment, terminal and pier services, purchased trucking and other transportation, and professional services. This category also includes costs related to materials, travel, casualty claims, environmental remediation, train accidents, property and sales tax, utilities and other items. Total purchased services and other expenses increased $416 million driven by the following:
•The inclusion of Quality Carriers' operations drove $257 million of additional costs.
•Higher operating support costs, primarily due to an increased active locomotive fleet, as well as higher intermodal terminal costs drove an increase of $80 million.
•All other costs increased $79 million primarily due to inflation and other non-significant costs, including $17 million in expenses related to the acquisition of Quality Carriers.
Depreciation expense primarily relates to recognizing the costs of capital assets, such as locomotives, railcars and track structure, over their respective useful lives, which are reviewed periodically as part of depreciation studies. This expense is impacted primarily by the capital expenditures made each year. Depreciation expense increased $37 million primarily due to a larger net asset base, which includes Quality Carriers' assets, partially offset by the impacts of the 2020 road and track depreciation study.
Fuel expense includes locomotive diesel fuel as well as non-locomotive fuel. This expense is largely driven by the market price and locomotive consumption of diesel fuel. Fuel expense increased $372 million primarily due to a 55% price increase in locomotive fuel prices and the inclusion of non-locomotive fuel used for trucking.
Equipment and Other Rents expense includes rent paid for freight cars owned by other railroads or private companies, net of rents received by CSXT for use of its equipment. This category of expenses also includes expenses for short-term and long-term leases of locomotives, railcars, containers, tractors and trailers, offices and other rentals. These expenses increased $26 million primarily due to increased car hire costs driven by higher days per load and the addition of Quality Carriers' costs, partially offset by other non-significant items.
Gains on Property Dispositions increased to $454 million in 2021 from $35 million in 2020 primarily due to the conveyance of a permanent land easement to the Commonwealth of Virginia that resulted in a $349 million gain in April 2021 as well as other property dispositions throughout 2021.

PART II
Interest Expense
Interest Expense includes interest on long-term debt, equipment obligations and finance leases. Interest expense decreased $32 million as a result of lower average interest rates and a lower average debt balance.
Other Income - Net
Other Income - Net includes investment gains, losses and interest income, as well as components of net periodic pension and post-retirement benefit cost and other non-operating activities. Other income increased $60 million primarily due to $48 million debt repurchase expense in the prior year and an increase in net pension benefit credits during 2021, partially offset by lower interest income.
Income Tax Expense
Income Tax Expense increased $308 million primarily due to higher earnings before income taxes, partially offset by favorable state legislative changes and adjustments to deferred taxes as a result of filing of the 2020 state tax returns.
Net Earnings and Earnings per Diluted Share
Net Earnings increased $1 billion to $3.8 billion, and earnings per diluted share increased $0.48 to $1.68, due to the factors mentioned above. Average shares outstanding was lower as a result of share repurchase activity during the year and had a favorable impact on earnings per diluted share.

2020 vs. 2019 Results of Operations
See below for discussion regarding operating expenses and earnings per share for the year ended December 31, 2020, compared to the year ended December 31, 2019. These discussion items have been updated to conform to the current presentation due to the reclassification of gains on property dispositions from the Purchased Services and Other caption to Gain on Property Dispositions, which had no impact on operating income, as well as the three-for-one stock split effective June 28, 2021.
Expense
In 2020, total expenses decreased $751 million, or 11%, compared to 2019. Descriptions of each expense category as well as significant year-over-year changes are described below.
Labor and Fringe expenses include employee wages and related payroll taxes, health and welfare costs, pension, other post-retirement benefits and incentive compensation. These expenses decreased $341 million due to the following items:
•Efficiency and volume savings of $288 million primarily resulted from structural changes to the train plan that resulted in reduced crew starts as well as lower headcount.
•Incentive compensation decreased $86 million primarily due to lower expected annual incentive payouts as well as higher prior year accelerated stock compensation expense for certain retirement-eligible employees.
•Other costs increased $33 million primarily due to inflation and several other non-significant items, including severance costs.
Purchased Services and Other expenses consist primarily of contracted services to maintain infrastructure and equipment, terminal and pier services and professional services. This category also includes costs related to materials, travel, casualty claims, environmental remediation, train accidents, property and sales tax, utilities and other items. Total purchased services and other expenses decreased $181 million driven by the following:
•Efficiency and volume savings of $185 million primarily resulted from lower operating support costs, lower terminal costs as a result of record productivity levels at intermodal terminals, and reduced equipment maintenance expenses.
•All other costs increased $4 million primarily due to inflation and other non-significant costs that were mostly offset by a $22 million non-railroad asset impairment in the prior year related to an intermodal terminal sale agreement.
Depreciation expense primarily relates to recognizing the costs of capital assets, such as locomotives, railcars and track structure, over their respective useful lives, which are reviewed periodically as part of depreciation studies. This expense is impacted primarily by the capital expenditures made each year. Depreciation expense increased $34 million primarily due to the impacts of the 2019 equipment depreciation study as well as a larger net asset base.

CSX CORPORATION
PART II
Fuel expense includes locomotive diesel fuel as well as non-locomotive fuel. This expense is largely driven by the market price and locomotive consumption of diesel fuel. Fuel expense decreased $365 million primarily due to a 31% price decrease that drove savings of $243 million, volume savings and a 5% improvement in fuel efficiency.
Equipment and Other Rents expense includes rent paid for freight cars owned by other railroads or private companies, net of rents received by CSXT for use of its equipment. This category of expenses also includes expenses for short-term and long-term leases of locomotives, railcars, containers, tractors and trailers, offices and other rentals. These expenses decreased $14 million primarily due to volume savings, partially offset by higher days per load for automotive and other merchandise markets that resulted in increased car hire costs.
Gains on Property Dispositions decreased to $35 million in 2020 from $151 million in 2019.
Net Earnings and Earnings per Diluted Share
Net Earnings decreased $566 million to $2.8 billion, and earnings per diluted share decreased $0.19 to $1.20. Average shares outstanding was lower as a result of share repurchase activity during the year and had a favorable impact on earnings per diluted share.

NON-GAAP MEASURES (Unaudited)
CSX reports its financial results in accordance with United States generally accepted accounting principles ("GAAP"). CSX also uses certain non-GAAP measures that fall within the meaning of Securities and Exchange Commission Regulation G and Regulation S-K Item 10(e), which may provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP measures do not have standardized definitions and are not defined by GAAP. Therefore, CSX’s non-GAAP measures are unlikely to be comparable to similar measures presented by other companies. The presentation of these non-GAAP measures should not be considered in isolation from, as a substitute for, or as superior to the financial information presented in accordance with GAAP. Reconciliations of non-GAAP measures to corresponding GAAP measures are below.
Free Cash Flow
Management believes that free cash flow is useful to investors as it is important in evaluating the Company’s financial performance. More specifically, free cash flow measures cash generated by the business after reinvestment. This measure represents cash available for both equity and bond investors to be used for dividends, share repurchases or principal reduction on outstanding debt. Free cash flow is calculated by using net cash from operations and adjusting for property additions and certain other investing activities, which includes proceeds from property dispositions. This measure should be considered in addition to, rather than a substitute for, cash provided by operating activities. Free cash flow before dividends increased $1.2 billion year-over-year to $3.8 billion primarily due to higher net cash provided by operating activities and higher proceeds and advances from property dispositions, including $400 million of proceeds related to the conveyance of a permanent land easement to the Commonwealth of Virginia in 2021. These increases were partially offset by higher property additions.
The following table reconciles cash provided by operating activities (GAAP measure) to free cash flow and adjusted free cash flow (both non-GAAP measures).

(a) Net cash provided by operating activities for the year ended December 31, 2020, includes the impact of $21 million paid to settle a liability for non-controlling interest in an affiliate.
(b) For the year ended December 31, 2020, certain other investing activities used in the calculation of free cash flow do not include the impact of a $30 million deposit paid by the Company related to its signed definitive agreement to acquire Pan Am Railways, Inc. This transaction remains subject to regulatory review and approval by the Surface Transportation Board. This deposit is included in the other investing activities total on the consolidated cash flow statement for the year ended December 31, 2020.

(a) The methodologies for calculating train velocity, dwell and cars online differ from those prescribed by the STB as the Company believes these numbers more accurately reflect railroad performance. CSXT will continue to report these metrics, using the prescribed methodology, to the STB on a weekly basis. See additional discussion on the Company's website.
Certain operating statistics are estimated and can continue to be updated as actuals settle.
Key Performance Measures Definitions:
Train Velocity - Average train speed between origin and destination in miles per hour (does not include locals, yard jobs, work trains or passenger trains). Train velocity measures the profiled schedule of trains (from departure to arrival and all interim time), and train profiles are periodically updated to align with a changing operation.
Dwell - Average amount of time in hours between car arrival to and departure from the yard.
Cars Online - Average number of active freight rail cars on lines operated by CSX, excluding rail cars that are being repaired, in storage, those that have been sold, or private cars dwelling at a customer location more than one day.
On-Time Originations - Percent of scheduled road trains that depart the origin yard on-time or ahead of schedule.
On-Time Arrivals - Percent of scheduled road trains that arrive at the destination yard on-time to within two hours of scheduled arrival. Carload Trip Plan Performance - Percent of measured cars destined for a customer that arrive at or ahead of the original estimated time of arrival, notification or interchange (as applicable).
Intermodal Trip Plan Performance - Percent of measured containers destined for a customer that arrive at or ahead of the original estimated time of arrival, notification or interchange (as applicable).
Fuel Efficiency - Gallons of locomotive fuel per 1,000 gross ton-miles.
Revenue Ton-Miles (RTM's) - The movement of one revenue-producing ton of freight over a distance of one mile.
Gross Ton-Miles (GTM's) - The movement of one ton of train weight over one mile. GTM's are calculated by multiplying total train weight by distance the train moved. Total train weight is comprised of the weight of the freight cars and their contents.
FRA Personal Injury Frequency Index - Number of FRA-reportable injuries per 200,000 man-hours.
FRA Train Accident Rate - Number of FRA-reportable train accidents per million train-miles.

CSX CORPORATION
PART II
The Company is committed to continuous improvement in safety and service performance through training, innovation and investment. Training and safety programs are designed to prevent incidents that can adversely impact employees, customers and communities. Technological innovations that can detect and avoid many types of human factor incidents are designed to serve as an additional layer of protection for the Company's employees. Continued capital investment in the Company's assets, including track, bridges, signals, equipment and detection technology also supports safety performance.
Despite the operating challenges presented by global supply disruptions and the ongoing COVID-19 pandemic, the Company remained focused on safety, service, and controlling costs. Train velocity declined 11% relative to 2020. Dwell increased by 15% and cars online increased 17% in 2021. Compared to 2020, carload and intermodal trip plan performance decreased 10% and 3%, respectively. CSX expects network fluidity to improve commensurate with ongoing hiring efforts and a return to more normal supply chain conditions.
From a safety perspective, the FRA personal injury index increased by 12% while the train-accident rate improved by 8% from the prior year. Safety remains a top priority at CSX, and the Company is committed to reducing risk and enhancing the overall safety of its employees, customers and communities in which the Company operates.
LIQUIDITY AND CAPITAL RESOURCES
Liquidity is a company’s ability to generate adequate amounts of cash to meet both current and future needs for obligations as they mature and to provide for planned capital expenditures, including those to address regulatory and legislative requirements. To have a complete picture of a company’s liquidity, its sources and uses of cash, balance sheet and external factors should be reviewed.
Significant Cash Flows
The following charts highlight the operating, investing and financing components of the change in cash and cash equivalents for operating, investing and financing activities for full years 2021 and 2020.
In 2021, the Company generated $5.1 billion of cash from by operating activities, which was $836 million higher than prior year primarily driven by higher cash-generating income and favorable working capital activities. Net cash used in investing activities was $1.9 billion, an increase in net spend of $1.2 billion from the prior year primarily as a result of decreased net sales of short-term investments and cash paid to acquire Quality Carriers, partially offset by higher proceeds and advances from property dispositions. Net cash used in financing activities was $4.1 billion, which represents an increase in net spend of $2.7 billion from the prior year primarily driven by higher share repurchases and lower proceeds from debt issuances, partially offset by lower debt repayments.

Sources of Cash and Liquidity
The Company has multiple sources of liquidity, including cash generated from operations and financing sources. Simultaneous with the filing of this Form 10-K, the Company intends to file a new shelf registration statement, which may be used to issue debt or equity securities at CSX’s discretion, subject to market conditions and CSX Board authorization. While CSX seeks to give itself flexibility with respect to cash requirements, there can be no assurance that market conditions would permit CSX to sell such securities on acceptable terms at any given time, or at all. In 2021, CSX did not issue any new long-term debt.
CSX has access to a $1.2 billion five-year unsecured revolving credit facility backed by a diverse syndicate of banks that expires in March 2024. As of December 31, 2021, the Company had no outstanding balances under this facility. See Note 10, Debt and Credit Agreements for more information. The Company also has a commercial paper program, backed by the revolving credit facility, under which the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount of $1.0 billion outstanding at any one time. As of December 31, 2021, the Company had no outstanding debt under the commercial paper program.
Uses of Cash
CSX uses current cash balances for general corporate purposes, which may include capital expenditures, working capital requirements, reduction or refinancing of outstanding indebtedness, redemptions and repurchases of CSX common stock, dividends to shareholders, acquisitions and other business opportunities, and contributions to the Company's qualified pension plan.
In 2021, CSX continued to invest in its business to create long-term value for shareholders. The Company is committed to maintaining and improving its existing infrastructure and to positioning itself for long-term, profitable growth through optimizing network and terminal capacity. Funds used for property additions are further described below.

| Fiscal Years
Capital Expenditures (Dollars in Millions) | 2021 |  | 2020 |  |
Track | $ | 876 |  |  | $ | 858 |  |  |
Bridges, Signals and Other | 567 |  |  | 508 |  |  |
Total Infrastructure | 1,443 |  |  | 1,366 |  |  |

Freight Cars | 29 |  |  | 21 |  |  |
Total Capital Expenditures | $ | 1,791 |  |  | 1,626 |  |  |

Planned capital investments for 2022 are expected to be approximately $2.0 billion. Of the 2022 investment, over 80% is expected to be used to sustain the core infrastructure and operating equipment. The remaining amounts will be used to promote profitable growth, including projects supporting service enhancements and productivity initiatives. CSX intends to fund capital investments through cash generated from operations.
CSX is continually evaluating market and regulatory conditions that could affect the Company’s ability to generate sufficient returns on capital investments. CSX may revise its future estimates for capital spending as a result of changes in business conditions, tax legislation or the enactment of new laws or regulations, which could have a material adverse effect on the Company’s operations and financial performance in the future (see Risk Factors under Item 1A of this Form 10-K).
CSX 2021 Form 10-K p.35

CSX CORPORATION
PART II
CSX is committed to returning cash to shareholders. Capital structure, capital investments and cash distributions, including dividends and share repurchases, are reviewed at least annually by the Board of Directors. On February 16, 2022, the Company's Board of Directors authorized a 7% increase in the quarterly cash dividend to $0.10 per common share effective March 2022. Management's assessment of market conditions and other factors guides the timing and volume of repurchases. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances.
Material Changes in the Consolidated Balance Sheets and Working Capital
CSX's balance sheet reflects its strong capital base and the impact of CSX's balanced approach in deploying capital for the benefit of its shareholders, which includes investments in infrastructure, dividend payments and share repurchases. Further, CSX is well positioned from a liquidity standpoint. The Company ended the year with $2.3 billion of cash, cash equivalents and short-term investments.
Total assets as well as total liabilities and shareholders' equity increased $738 million from prior year end. The increase in total assets was primarily due to a net increase in property of $571 million attributable to capital expenditures and the consolidation of Quality Carrier's properties, the recognition of $393 million of goodwill and intangible assets related to the acquisition of Quality Carriers, a $236 million increase in accounts receivable commensurate with higher revenue and a $226 million increase in net assets for qualified pension plans primarily driven by favorable discount rates. These increases were partially offset by the $890 million decrease in cash described above.
Total liabilities increased $348 million from year end primarily due to an increase in deferred tax liabilities of $215 million driven by accelerated tax depreciation, an increase in accounts payable of $154 million due to the timing of payments, an increase in labor and fringe benefit payable of $148 million partly due higher expected incentive compensation payouts, the assumption of $68 million in debt as a result of the acquisition of Quality Carriers, and an increase in income and other taxes payable of $61 million. These and other increases were offset by debt repayments of $426 million. Total shareholders' equity increased $390 million from year end primarily driven by net earnings of nearly $3.8 billion, mostly offset by share repurchases of $2.9 billion and dividends paid of $839 million.
Working capital is considered a measure of a company’s ability to meet its short-term needs. CSX had a working capital surplus of $1.6 billion at December 2021 and $2.4 billion at December 2020, a decrease of $782 million. The decrease in current assets was primarily driven by the net decrease in cash described above, partially offset by the increase in accounts receivable. The increase in current liabilities was due to higher accounts payable and labor and fringe payable, partially offset by lower current maturities of long-term debt.
The Company’s working capital balance varies due to factors such as the timing of scheduled debt payments and changes in cash and cash equivalent balances. Although the Company currently has a surplus, a working capital deficit is not unusual for CSX or other companies in the industry and does not indicate a lack of liquidity. The Company continues to maintain adequate current assets to satisfy current liabilities and maturing obligations when they come due. Furthermore, CSX has sufficient financial capacity, including its revolving credit facility, commercial paper program and shelf registration statement to manage its day-to-day cash requirements and any anticipated obligations. The Company from time to time accesses the credit markets for additional liquidity.

Completed and Pending Transactions
Acquisition of Quality Carriers, Inc.
On July 1, 2021, CSX acquired Quality Carriers, Inc. from Quality Distribution, Inc. for a purchase price of $544 million in cash, which is presented on the statement of cash flows net of $3 million cash acquired. This transaction was funded by cash on hand. For further details, refer to Note 17, Business Combinations.
Proposed Acquisition of Pan Am Systems, Inc.
On November 30, 2020, CSX signed a definitive agreement to acquire Pan Am Systems, Inc. (“Pan Am”) which is the parent company of Pan Am Railways, Inc. who jointly owns Pan Am Southern, LLC with a subsidiary of Norfolk Southern Corporation. Pan Am owns and operates a highly integrated, nearly 1,200-mile rail network and has a joint interest in the more than 600-mile Pan Am Southern system. This acquisition, if approved, will expand CSX’s reach in the Northeastern United States. Assets and facilities to be acquired as part of the proposed transaction include road and track assets, work equipment, land, buildings and other assets. On February 25, 2021, the Company began the process of seeking approval from the STB. On January 13 and 14, 2022, the Company participated in a hearing before the STB to discuss the proposed transaction and a decision is expected by mid-April 2022. This proposed acquisition is not expected to be material with respect to the Company's financial statements when reviewed under the quantitative and qualitative considerations of Regulation S-X Article 11 and ASC 805, Business Combinations.
Sale of Property Rights to the Commonwealth of Virginia
On March 26, 2021, the Company entered into a comprehensive agreement to sell certain property rights in three CSX-owned line segments to the Commonwealth of Virginia (“Commonwealth”) over three phases for a total of $525 million. The timing and amount of gains recognized are based on the allocation of fair value to each conveyance, the timing of future conveyances and collectability. In April 2021, upon closing of the first phase of the agreement, the Company collected $200 million in proceeds and recognized a $349 million gain. In fourth quarter 2021, the Company collected additional proceeds of $200 million, a portion of which was attributable to the first phase with the remaining attributable to the second phase. There was no gain recognized in fourth quarter 2021 related to this agreement. As the second phase closed on January 10, 2022, the resulting $20 million gain will be recognized in first quarter 2022.
The Company anticipates closing on the remaining conveyances by the end of 2022, which will result in future cash proceeds and gains. As of December 31, 2021, the carrying values of the remaining assets subject to this transaction were not material.

Credit Ratings
Credit ratings reflect an independent agency’s judgment on the likelihood that a borrower will repay a debt obligation at maturity. The ratings reflect many considerations, such as the nature of the borrower’s industry and its competitive position, the size of the company, its liquidity and access to capital and the sensitivity of a company’s cash flows to changes in the economy. The two largest rating agencies, Standard & Poor’s Ratings Services (“S&P”) and Moody’s Investors Service (“Moody’s”), use alphanumeric codes to designate their ratings. The highest quality rating for long-term credit obligations is AAA and Aaa for S&P and Moody’s, respectively. A credit rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency.
The cost and availability of unsecured financing are materially affected by CSX's long-term credit ratings. CSX's credit ratings remained stable during 2021. As of December 2021 and December 2020, S&P's long-term rating on CSX was BBB+ (Stable), and Moody's was Baa1 (Stable). Ratings of BBB- and Baa3 or better by S&P and Moody’s, respectively, reflect ratings on debt obligations that fall within a band of credit quality considered to be investment grade. If CSX's credit ratings were to decline to below investment-grade levels, the Company could experience significant increases in its interest cost for new debt. In addition, a decline in CSX’s credit ratings to below investment grade levels could adversely affect the market’s demand, and thus the Company’s ability to readily issue new debt. The Company is committed to maintaining an investment-grade credit profile.
Guaranteed Notes Issued By CSXT
In 2007, CSXT, a wholly-owned subsidiary of CSX Corporation, issued in a registered public offering $381 million of secured equipment notes maturing in 2023. CSX Corporation has fully and unconditionally guaranteed the notes. At CSXT’s option, CSXT may redeem any or all of the notes, in whole or in part, at any time, at the redemption price including premium. In the case of loss or destruction of any item of equipment securing the notes, if CSXT does not substitute another item of equipment for the item suffering such loss or destruction, CSXT will be required to redeem the notes in part at par. The guarantee of the notes will rank equally in right of payment with all existing and future senior obligations of CSX Corporation and will be effectively subordinated to all future secured indebtedness of CSX Corporation to the extent of the assets securing such indebtedness. The guarantee is subject to release in limited circumstances only upon the occurrence of certain customary conditions. As of December 31, 2021, the principal balance of these secured equipment notes was $149 million.
In accordance with SEC rules, including amendments adopted in 2020, CSX is not required to present separate condensed consolidating financial information for wholly-owned subsidiaries who issued or guaranteed notes. Additionally, presentation of combined summary financial information regarding subsidiary issuers and guarantors is not required because the assets, liabilities and results of operations of the combined issuers and guarantors of the notes are not materially different from the corresponding amounts presented in the consolidated financial statements.

CONTRACTUAL OBLIGATIONS, OTHER COMMITMENTS AND OFF-BALANCE SHEET ARRANGEMENTS
Contractual Obligations
CSX is party to contractual arrangements that obligate the Company to make future cash payments. These obligations impact the Company’s liquidity and capital resource needs. The Company’s contractual obligations primarily consist of long-term debt and related interest payments, purchase commitments, leases, other-post employment benefits and agreements with Conrail.
•As of December 31, 2021, the Company had outstanding fixed-rate notes with varying maturities. See Note 10, Debt and Credit Agreements, for additional information related to future debt payments. Future interest payments associated with outstanding debt total $13.5 billion, with $699 million payable in 2022.
•Purchase commitments consist of CSX’s long-term locomotive maintenance program and other commitments to purchase technology, communications, railcar maintenance and other services. See Note 8, Commitments and Contingencies, for additional information about future payments related to purchase commitments.
•The Company’s leases include property, equipment, and line leases. See Note 7, Leases, for additional information about future payments related to leases.
•Other post-employment benefits include estimated other post-retirement medical and life insurance payments and payments under non-qualified pension plans that are unfunded. See Note 9, Employee Benefit Plans, for additional information about future payments under such plans.
•Conrail owns rail infrastructure and operates for the joint benefit of CSX and NS. This is known as the shared asset area. Conrail charges fees for right-of-way usage, equipment rentals and transportation, switching and terminal service charges in the shared asset area. See Note 15, Investment in Affiliates and Related-Party Transactions, for additional information about future payments related to agreements with Conrail.
Other Commitments and Off-Balance Sheet Arrangements
Other commitments total $153 million and primarily consist of guarantees, letters of credit and surety bonds, none of which are individually significant. These off-balance sheet arrangements are not reasonably likely to have a material effect on the Company's financial condition, results of operations or liquidity.

LABOR AGREEMENTS
Approximately 16,500 of the Company's over 20,900 employees are members of a labor union. For the 13 rail unions that participate in national bargaining, a round of negotiations for benefits, wages and work rules is underway. Typically, these negotiations take several years. Current agreements remain in place until modified by new agreements.
CRITICAL ACCOUNTING ESTIMATES
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates in reporting the amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and certain revenues and expenses during the reporting period. Actual results may differ from those estimates. These estimates and assumptions are discussed with the Audit Committee of the Board of Directors on a regular basis. Significant estimates using management judgment are made for the following areas:
•personal injury and environmental reserves;
•pension and post-retirement medical plan accounting;
•depreciation policies for assets under the group-life method; and
•goodwill and other intangible assets.
Personal Injury and Environmental Reserves
Personal Injury
Personal Injury reserves of $118 million and $131 million for 2021 and 2020, respectively, represent liabilities for employee work-related and third-party injuries. CSXT retains an independent actuary to assist management in assessing the value of personal injury claims. The methodology used by the actuary includes a development factor to reflect growth or reduction in the value of these personal injury claims. It is based largely on CSXT's historical claims and settlement experience. Actual results may vary from estimates due to the number, type and severity of the injury, costs of medical treatments and uncertainties in litigation. For additional details, including a description of our related accounting policies, see Note 5, Casualty, Environmental and Other Reserves, in the consolidated financial statements.
Environmental
Environmental reserves were $108 million and $76 million in 2021 and 2020, respectively. The Company is a party to various proceedings related to environmental issues, including administrative and judicial proceedings involving private parties and regulatory agencies. The Company has been identified as a potentially responsible party at approximately 220 environmentally impaired sites. The Company reviews its potential liability with respect to each site identified, giving consideration to a number of factors such as:
•type of clean-up required;
•nature of the Company’s alleged connection to the location (e.g., generator of waste sent to the site or owner or operator of the site);
•extent of the Company’s alleged connection (e.g., volume of waste sent to the location and other relevant factors); and
•number, connection and financial viability of other named and unnamed potentially responsible parties at the location.

Conditions that are currently unknown could, at any given location, result in additional exposure, the amount and materiality of which cannot presently be reasonably estimated. For additional details, including a description of our related accounting policies, see Note 5, Casualty, Environmental and Other Reserves, in the consolidated financial statements.
Pension and Post-retirement Medical Plan Accounting
The Company sponsors defined benefit pension plans principally for salaried, management personnel. For employees hired prior to 2003, the plans provide eligible employees with retirement benefits based predominantly on years of service and compensation rates near retirement. For employees hired between 2003 and 2019, benefits are determined based on a cash balance formula, which provides benefits by utilizing interest and pay credits based upon age, service and compensation. Beginning in 2020, the CSX Pension Plan was closed to new participants. As of December 2021, the projected benefit obligation for the Company’s pension plans was $3.0 billion.
In addition to these plans, the Company sponsors a post-retirement medical plan and a life insurance plan that provide certain benefits to full-time, salaried, management employees hired prior to 2003 upon their retirement if certain eligibility requirements are met. Beginning in 2019, both the life insurance benefit for eligible active management employees and health savings account contributions made by the Company to eligible retirees younger than 65 were eliminated. Beginning in 2020, the employer-funded health reimbursement arrangements for eligible retirees 65 years or older were eliminated. As of December 2021, the projected benefit obligation for the Company’s other post-retirement benefit plans was $81 million.
For information related to the funded status of the Company's pension and other post-retirement benefit plans, see Note 9, Employee Benefit Plans.
The accounting for these plans is subject to the guidance provided in the Compensation-Retirement Benefits Topic in the ASC. This rule requires that management make certain assumptions relating to the following:
•discount rates used to measure future obligations and interest expense;
•long-term rate of return on plan assets;
•salary scale inflation rates; and
•other assumptions.
The Company engages independent actuaries to compute the amounts of liabilities and expenses relating to these plans subject to the assumptions that the Company determines are appropriate based on historical trends, current market rates and future projections. These amounts are reviewed by management.
CSX 2021 Form 10-K p.41

CSX CORPORATION
PART II
Critical Accounting Estimates, continued
Discount Rates
Discount rates affect the amount of liability recorded and the service and interest cost components of pension and post-retirement expense. Discount rates reflect the rates at which pension and other post-retirement benefits could be effectively settled, or in other words, how much it would cost the Company to buy enough high quality bonds to generate cash flow equal to the Company's expected future benefit payments. The Company determines the discount rate based on the market yield as of year-end for high quality corporate bonds whose maturities match the plans' expected benefit payments.
The Company measures the service and interest cost components of the net pension and post-retirement benefits expense by using individual spot rates matched with separate cash flows for each future year. Under the spot rate approach, individual spot discount rates along the same high quality corporate bonds yield curve used to measure the pension and post-retirement benefit liabilities are applied to the relevant projected cash flows at the relevant maturity.
The weighted average discount rates used by the Company to value its 2021 pension and post-retirement obligations are 2.78% and 2.51%, respectively. For 2020, the weighted average discount rates used by the Company to value its pension and post-retirement obligations were 2.43% and 2.07%, respectively. Discount rates may differ for pension and post-retirement benefits due to varying duration of the liabilities for projected payments for each plan. As of December 2021, the estimated duration of pensions and post-retirement benefits is approximately 12 years and 8 years, respectively.
Each year, these discount rates are reevaluated and adjusted using the current market interest rates for high quality corporate bonds to reflect the best estimate of the current effective settlement rates. In general, if interest rates decline or rise, the assumed discount rates will change.
Long-term Rate of Return on Plan Assets
The expected long-term average rate of return on plan assets reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for benefits included in the projected benefit obligation. In estimating that rate, the Company gives appropriate consideration to the returns being earned by the plan assets in the funds and the rates of return expected to be available for reinvestment as well as the current and projected asset mix of the funds. Management, with the assistance of an outsourced investment manager, balances market expectations obtained from various investment managers with both market and actual plan historical returns to develop a reasonable estimate of the expected long-term rate of return on assets. As this assumption is long term, the annual review may result in less frequent adjustment than other assumptions used in pension accounting. The long-term rate of return on plan assets used by the Company to value its benefit cost for the subsequent plan year was 6.75% in both 2021 and 2020.
Salary Scale Inflation Rates
Salary scale inflation rates are based on current trends and historical data accumulated by the Company. The Company reviews recent wage increases and management incentive compensation payments over the past five years in its assessment of salary scale inflation rates. The Company used a salary scale rate of 4.60% in both 2021 and 2020 to value its pension obligations.
Other Assumptions
The calculations made by the actuaries also include assumptions relating to health care cost trend rates, mortality rates, turnover and retirement age. These assumptions are based upon historical data, recent plan experience and industry trends and are determined by management.

2022 Estimated Pension and Post-retirement Expense
Net periodic pension and post-retirement benefits expenses for 2022 are expected to be credits of $42 million and $5 million, respectively. Net periodic pension and post-retirement benefits expenses for 2022 are expected to include service cost expense of $32 million and $1 million, respectively. Service cost expense is included in labor and fringe on the consolidated income statement and all other components of net pension expense and post-retirement benefits expense are included in other income - net. Net periodic pension expense and post-retirement benefits expense in 2021 were credits of $17 million and $5 million, respectively. The net increase in the expected credit is primarily due to impacts from the increase in discount rates and recent favorable pension asset experience.
The following sensitivity analysis illustrates the effects of a 1% change in certain assumptions like discount rates, long-term rate of return and salaries on the 2022 estimated pension and post-retirement expense:

(Dollars in Millions) |  | Pension Expense |  | Post-Retirement Expense

Long-term Rate of Return |  | $ | 28 |  |  | N/A
Salary Inflation |  | $ | 4 |  |  | N/A

Depreciation Policies for Assets Utilizing the Group-Life Method
The depreciable assets of the Company are depreciated using either the group-life or straight-line method of accounting, which are both acceptable depreciation methods in accordance with GAAP. The Company depreciates its railroad assets, including main-line track, locomotives and freight cars, using the group-life method of accounting. Assets depreciated under the group-life method comprise 86% of total fixed assets of $46.5 billion on a gross basis at December 31, 2021. The remaining depreciable assets of the Company, including non-railroad assets and assets under finance leases, are depreciated using the straight-line method on a per asset basis. Land is not depreciated.
Management performs a review of depreciation expense and useful lives on a regular basis. Under the group-life method, the service lives and salvage values for each group of assets are determined by completing periodic depreciation studies and applying management’s methods to determine the service lives of its properties. There are several factors taken into account during the depreciation study and they include:
•statistical analysis of historical life and salvage data for each group of property;
•statistical analysis of historical retirements for each group of property;
•evaluation of current operations;
•evaluation of technological advances and maintenance schedules;
•previous assessment of the condition of the assets;
•management's outlook on the future use of certain asset groups;
•expected net salvage to be received upon retirement; and
•comparison of assets to the same asset groups with other companies.

The STB requires depreciation studies be performed every three years for equipment assets (e.g., locomotives and freight cars) and every six years for road and track assets (e.g., bridges, signals, rail, ties, and ballast). The Company completed a depreciation study for its road and track assets in 2020 and for equipment assets in 2019, both of which resulted in changes to accumulated depreciation, service lives, salvage values, and other related factors for certain assets. Recent experience with depreciation studies has resulted in changes to accumulated depreciation and depreciation rates that did not materially affect the Company's depreciation expense of $1.4 billion, $1.4 billion and $1.3 billion for 2021, 2020 and 2019, respectively. A 1% change in the average estimated useful life of all group-life assets would result in an approximate $12 million change to the Company’s annual depreciation expense. For additional details, including a more detailed description of our related accounting policies, see Note 6, Properties, in the consolidated financial statements.
Goodwill and Intangible Assets
As of December 2021, the Company had $451 million of Goodwill and Other Intangibles - Net. CSX recognized $213 million of goodwill and $180 million of intangible assets as a result of the Quality Carriers acquisition effective July 1, 2021.
In applying the acquisition method of accounting for business combinations, management must determine the fair value of assets acquired and liabilities assumed in order to properly allocate purchase price consideration between depreciable and amortizable assets and goodwill. The fair values assigned to tangible and intangible assets acquired and liabilities assumed are based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. Estimates and assumptions include, but are not limited to, the cash flows that an asset is expected to generate in the future and the appropriate weighted-average cost of capital.
CSX evaluates goodwill and intangible assets for impairment on an annual basis, or sooner if indicators of impairment exist. In performing the qualitative impairment assessment, CSX considers relevant events and conditions, including but not limited to: macroeconomic trends, industry and market conditions, overall financial performance, company-specific events, and legal and regulatory factors. If the qualitative assessments indicate that it is more likely than not that the fair value of the reporting unit or intangible assets are less than their carrying amounts, the Company would perform a quantitative impairment test. If the carrying amount of the reporting unit's goodwill or intangible asset exceeded the fair value under the quantitative test, an impairment loss would be recorded. Measurement of the fair value of a reporting unit could be based on one or more of the following fair value measures: amounts at which the unit as a whole could be bought or sold in a current transaction between willing parties, present value techniques of estimated future cash flows, valuation techniques based on multiples of earnings or revenue, or a similar performance measure.

PART II
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
Changes in interest rates may impact the cost of future long-term debt issued by the Company, and as a result, represent interest rate risk to the Company. In an effort to manage this risk, CSX may use certain financial instruments such as interest rate forward contracts. The following information, together with information included in Note 10, Debt and Credit Agreements, describes the key aspects of such contracts and the related market risk to CSX.
Changes in interest rates could impact the fair value of the Company's forward starting interest rate swap. On both April 29, 2020, and July 9, 2020, the Company executed a forward starting interest rate swap with a notional value of $250 million for an aggregate notional value of $500 million. These swaps were effected to hedge the benchmark interest rate associated with future interest payments related to the anticipated refinancing of notes due in 2027. The Company recognized an unrealized gain of $8 million and $62 million net of tax during the years ended December 31, 2021 and 2020, respectively, in the consolidated statements of comprehensive income with the related asset on the balance sheet as of December 31, 2021. Upon settlement of the swaps, which expire in 2027, the unrealized gain or loss in AOCI will be recognized in earnings as an adjustment to interest expense over the same period during which the hedged transaction affects earnings. As of December 31, 2021, the potential change in fair value resulting from a hypothetical 10% change in interest rates would not be material.
As of December 31, 2021, CSX has no floating rate debt obligations outstanding. However, changes in interest rates could impact the fair value (but not the carrying value) of the Company's fixed rate long-term debt. The potential decrease in fair value of the Company's fixed rate long-term debt resulting from a hypothetical 10% increase in U.S. Treasury rates, or approximately 15 basis points, is estimated to be $448 million as of December 31, 2021 and $428 million as of December 31, 2020. The underlying fair values of the Company's long-term debt were estimated based on quoted market prices or on the current rates offered for debt with similar terms and maturities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of CSX Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of CSX Corporation (the Company) as of December 31, 2021 and 2020, and the related consolidated statements of income, comprehensive income, cash flows, and changes in shareholders’ equity for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 16, 2022 expressed an unqualified opinion thereon.

| Depreciation Policies for Assets Utilizing the Group-Life Method
Description of the Matter | At December 31, 2021, assets depreciated under the group-life method comprised 86% of total gross fixed assets of $46.5 billion. As discussed in Note 6 of the consolidated financial statements, the group-life method aggregates assets with similar lives and characteristics into groups and depreciates each of these groups as a whole. When using the group-life method, an underlying assumption is that each group of assets, as a whole, is used and depreciated to the end of the group’s recoverable life. The Company utilizes different depreciable asset categories to account for depreciation expense for the railroad assets that are depreciated under the group-life method. Under the group-life method, depreciation studies are completed to review asset service lives, salvage values, accumulated depreciation and other factors related to group assets. Depreciation studies are performed every three years for equipment assets and every six years for road and track assets. A depreciation study was performed in 2019 for equipment assets and 2020 for road and track assets. The most recent depreciation studies are reviewed by management each year through an annual data review to determine if there have been significant factors that result in changes to the group-life method key assumptions. Auditing depreciation expense for assets subject to the group-life method was complex and required the involvement of specialists due to the nature of the methods used in the depreciation studies to determine the useful service lives and salvage values of the Company’s assets. These methods have a significant effect on depreciation expense.
How We Addressed the Matter in Our Audit | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s process related to the assessment of periodic depreciation studies and annual data reviews of its group-life assets. For example, we tested controls over management’s review of asset activity and assumptions that could impact the most recent depreciation study of equipment and road and track assets. To test the estimated useful lives and salvage values of the Company’s group-life assets, we performed audit procedures that included, among others: obtaining the periodic depreciation studies and annual data reviews provided by the Company’s third-party specialist; assessing the completeness and accuracy of the data provided by management to the third-party specialist; and including a specialist on our team to evaluate the methods used by the third-party specialist and management in determining the average service lives and salvage values of assets to perform the depreciation studies and any changes to the service lives and salvage values, if any, resulting from the annual data reviews. We compared the significant methods used by management to those used throughout the industry and within other depreciation studies. We assessed the historical accuracy of management’s estimates via retrospective review and independently calculated the current year depreciation rates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1. Nature of Operations and Significant Accounting Policies
Business
CSX Corporation together with its subsidiaries ("CSX" or the “Company”), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based transportation services including traditional rail service, the transport of intermodal containers and trailers, as well as other transportation services such as rail-to-truck transfers and bulk commodity operations.
CSX Transportation, Inc.
CSX’s principal operating subsidiary, CSX Transportation, Inc. (“CSXT”), provides an important link to the transportation supply chain through its approximately 19,500 route mile rail network, which serves major population centers in 23 states east of the Mississippi River, the District of Columbia and the Canadian provinces of Ontario and Quebec. It has access to over 70 ocean, river and lake port terminals along the Atlantic and Gulf Coasts, the Mississippi River, the Great Lakes and the St. Lawrence Seaway. The Company’s intermodal business links customers to railroads via trucks and terminals. CSXT also serves thousands of production and distribution facilities through track connections to more than 230 short-line and regional railroads.
CSXT is also responsible for the Company's real estate sales, leasing, acquisition and management and development activities. Substantially all of these activities are focused on supporting railroad operations.
Other Entities
In addition to CSXT, the Company’s subsidiaries include Quality Carriers, Inc. ("Quality Carriers"), CSX Intermodal Terminals, Inc. (“CSX Intermodal Terminals”), Total Distribution Services, Inc. (“TDSI”), Transflo Terminal Services, Inc. (“Transflo”), CSX Technology, Inc. (“CSX Technology”) and other subsidiaries. Effective July 1, 2021, CSX acquired Quality Carriers, the largest provider of bulk liquid chemicals truck transportation in North America, from Quality Distribution, Inc. For further details, refer to Note 17, Business Combinations. CSX Intermodal Terminals owns and operates a system of intermodal terminals, predominantly in the eastern United States, and also provides drayage services (the pickup and delivery of intermodal shipments) for certain customers. TDSI serves the automotive industry with distribution centers and storage locations. Transflo connects non-rail served customers to the many benefits of rail by transferring products from rail to trucks. The biggest Transflo markets are chemicals and agriculture, which include shipments of plastics and ethanol. CSX Technology and other subsidiaries provide support services for the Company.

Lines of Business
During 2021, the Company's services generated $12.5 billion of revenue and served four primary lines of business: merchandise, intermodal, coal and trucking.
•The merchandise business shipped 2.6 million carloads (41% of volume) and generated 60% of revenue in 2021. The Company’s merchandise business is comprised of shipments in the following diverse markets: chemicals, agricultural and food products, minerals, automotive, forest products, metals and equipment, and fertilizers.
•The intermodal business shipped 3.0 million units (48% of volume) and generated 16% of revenue in 2021. The intermodal business combines the superior economics of rail transportation with the flexibility of trucks and offers a cost and environmental advantage over long-haul trucking. Through a network of approximately 30 terminals, the intermodal business serves all major markets east of the Mississippi River and transports mainly manufactured consumer goods in containers, providing customers with truck-like service for longer shipments.
•The coal business shipped 706 thousand carloads (11% of volume) and generated 14% of revenue in 2021. The Company transports domestic coal, coke and iron ore to electricity-generating power plants, steel manufacturers and industrial plants as well as export coal to deep-water port facilities. Approximately one-quarter of export coal and the majority of the domestic coal that the Company transports is used for generating electricity or industrial purposes.
•The trucking business generated 3% of revenue in 2021. Trucking revenue includes revenue from the operations of Quality Carriers, which was acquired by CSX effective July 1, 2021.
Other revenue accounted for 7% of the Company’s total revenue in 2021. This category includes revenue from regional subsidiary railroads and incidental charges, including intermodal storage and equipment usage, demurrage and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.
Employees
The Company's number of employees was more than 20,900 as of December 2021, which includes approximately 16,500 union employees. Most of the Company’s employees provide or support transportation services.

Basis of Presentation
In the opinion of management, the accompanying consolidated financial statements contain all normal, recurring adjustments necessary to fairly present the financial position of CSX and its subsidiaries at December 31, 2021 and December 31, 2020, and the consolidated statements of income, comprehensive income, cash flows and changes in shareholders’ equity for fiscal years 2021, 2020 and 2019. Where applicable, prior year information has been reclassified to conform to current presentation. In addition, management has evaluated and disclosed all material events occurring subsequent to the date of the financial statements up to the date this annual report is filed on Form 10-K.
Common Stock Split
On June 4, 2021, CSX announced a three-for-one split of the Company’s common stock in the form of a stock dividend. Each shareholder of record on June 18, 2021, received two additional shares of common stock for each share held as of this record date. The new shares were distributed after close of trading on June 28, 2021. All prior period share and per share amounts, common stock, other capital, and retained earnings presented herein have been retroactively adjusted to reflect the impact of the stock split. Proportional adjustments were also made to outstanding awards under the Company's stock-based compensation plans.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates in reporting the amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of certain revenues and expenses during the reporting period. Actual results may differ from those estimates. Critical accounting estimates using management judgment are made for the following areas:
•personal injury and environmental reserves (see Note 5, Casualty, Environmental and Other Reserves);
•pension and post-retirement medical plan accounting (see Note 9, Employee Benefit Plans);
•depreciation policies for assets under the group-life method (see Note 6, Properties); and
•goodwill and other intangible assets (see Note 17, Business Combinations and Note 18, Goodwill and Other Intangibles - Net).
Fiscal Year
The Company's fiscal periods are based upon the calendar year. Except as otherwise specified, references to full years indicate CSX’s fiscal years ended on December 31, 2021, December 31, 2020, and December 31, 2019.
Principles of Consolidation
The consolidated financial statements include results of operations of CSX and subsidiaries over which CSX has majority ownership or financial control. All significant intercompany accounts and transactions have been eliminated. Most investments in companies that were not majority-owned were carried at cost (if less than 20% owned and the Company has no significant influence) or were accounted for under the equity method (if the Company has significant influence but does not have control). These investments are reported within Investment in Affiliates and Other Companies on the consolidated balance sheets.

Cash and Cash Equivalents
On a daily basis, cash in excess of current operating requirements is invested in various highly liquid investments having a typical maturity date of three months or less at the date of acquisition. These investments are carried at cost, which approximates market value, and are classified as cash equivalents.
Investments
Investments in instruments with original maturities greater than three months that will mature in less than one year are classified as short-term investments. Investments with original maturities of one year or greater are initially classified within other long-term assets, and the classification is re-evaluated at each balance sheet date.
Materials and Supplies
Materials and supplies in the consolidated balance sheets are carried at average cost and consist primarily of parts used in the repair and maintenance of track structure, equipment, and CSXT’s freight car and locomotive fleets, as well as fuel.
New Accounting Pronouncements
In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. As the London Interbank Offered Rate ("LIBOR") will no longer be available beginning July 2023, this standard update provides practical expedients for contract modifications made as part of the transition from LIBOR to alternative reference rates. CSX's revolving line of credit currently uses LIBOR as a reference rate. This standard update can be adopted prospectively through December 31, 2022. The Company continues to evaluate the impact of this standard update, but does not anticipate that adoption will have a material impact on the Company's results of operations or financial position.
In November 2021, the FASB issued ASU 2021-10, Disclosure by Business Entities about Government Assistance. This standard update requires annual disclosure of the nature of any government assistance received, accounting policies related to such assistance and the effect of that assistance on the entity’s financial statements. The Company is required to adopt this guidance effective January 2022, though early adoption is permitted. The Company is currently evaluating the impact of these amendments on its disclosures, but this standard update will not impact the Company's results of operations or financial position.

NOTE 2. Earnings Per Share
The following table sets forth the computation of basic earnings per share and earnings per share, assuming dilution:

| Fiscal Years
| 2021 |  | 2020 |  | 2019
Numerator (Dollars in Millions): |  |  |
Net Earnings | $ | 3,781 |  |  | $ | 2,765 |  |  | $ | 3,331 |
Dividend Equivalents on Restricted Stock | — |  |  | — |  |  | — |
Net Earnings, Attributable to Common Shareholders | $ | 3,781 |  |  | $ | 2,765 |  |  | $ | 3,331 |
Denominator (Units in Millions): |  |  |  |  |
Average Common Shares Outstanding | 2,250 |  |  | 2,300 |  |  | 2,389 |
Other Potentially Dilutive Common Shares | 5 |  |  | 5 |  |  | 6 |
Average Common Shares Outstanding, Assuming Dilution | 2,255 |  |  | 2,305 |  |  | 2,395 |
Net Earnings Per Share, Basic | $ | 1.68 |  |  | $ | 1.20 |  |  | $ | 1.39 |
Net Earnings Per Share, Assuming Dilution | $ | 1.68 |  |  | $ | 1.20 |  |  | $ | 1.39 |

Basic earnings per share is based on the weighted-average number of shares of common stock outstanding. Earnings per share, assuming dilution, is based on the weighted-average number of shares of common stock outstanding and common stock equivalents adjusted for the effects of common stock that may be issued as a result of potentially dilutive instruments. CSX's potentially dilutive instruments are made up of equity awards including performance units and employee stock options.
When calculating diluted earnings per share, the potential shares that would be outstanding if all outstanding stock options were exercised are included. This number is different from outstanding stock options, which is included in Note 4, Stock Plans and Share-Based Compensation, because it is offset by shares CSX could repurchase using the proceeds from these hypothetical exercises to obtain the common stock equivalent. The total average outstanding equity awards that were excluded from the diluted earnings per share calculation because their effect was antidilutive is in the table below.

| Fiscal Years
| 2021 |  | 2020 |  | 2019
Antidilutive stock options excluded from Diluted EPS (in millions) | 2 |  |  | 6 |  |  | 3 |

Share Repurchase Programs
In January 2019, the Company announced a $5 billion share repurchase program ("January 2019 program"). During June 2021, this program was completed, and the Company began repurchasing shares under the $5 billion share repurchase program announced October 21, 2020 (“October 2020 program”). Total repurchase authority remaining as of December 31, 2021, was $3.0 billion. A portion of share repurchases in January 2019 were completed under a previous share repurchase program announced in October 2017.

NOTE 2. Earnings Per Share, continued
Share repurchases may be made through a variety of methods including, but not limited to, open market purchases, purchases pursuant to Rule 10b5-1 plans, accelerated share repurchases and negotiated block purchases. The timing of share repurchases depends upon management's assessment of marketplace conditions and other factors, and the program remains subject to the discretion of the Board of Directors. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances. Shares are retired immediately upon repurchase. In accordance with the Equity Topic in the Accounting Standards Codification ("ASC"), the excess of repurchase price over par value is recorded in retained earnings.
Share Repurchase Activity
During 2021, 2020, and 2019, CSX repurchased the following shares:

| Fiscal Years
| 2021 |  | 2020 |  | 2019
Shares Repurchased (Units in Millions) | 90 |  |  | 38 |  |  | 144 |
Cost of Shares (Dollars in Millions) | $ | 2,886 |  |  | $ | 867 |  |  | $ | 3,373 |
Average Price Paid per Share | $ | 31.91 |  |  | $ | 22.90 |  |  | $ | 23.51 |

On October 17, 2019, the Company repurchased 14.1 million (split-adjusted) shares for $319 million from MR Argent Advisor LLC, a CSX shareholder, on behalf of certain limited partners of its affiliated funds (“Mantle Ridge”) under the January 2019 share repurchase program. A member of CSX’s Board of Directors, Paul C. Hilal, founded and controls Mantle Ridge and each of its related entities. Shares purchased from Mantle Ridge are included in the table above.
Periodically, CSX enters into structured agreements for the repurchase of CSX shares. Upon execution of each agreement, the Company pays a fixed amount of cash in exchange for the right to receive either CSX stock or a predetermined amount of cash, including a premium. Shares acquired through these structured share repurchase agreements were recorded in common stock and retained earnings and are included in the share repurchases table above. Premiums received were not material. As a result of entering into and settling structured share repurchase agreements, the Company paid a net total of approximately $378 million and received approximately 12 million shares during the twelve months ended 2021. As of December 31, 2021, no such agreements were outstanding.
Accelerated Share Repurchases
Shares repurchased under accelerated share repurchase agreements are included in the table above. In December 2020, the Company completed an accelerated share repurchase subject to an agreement to repurchase shares of the Company’s stock under the January 2019 program. Under this agreement, the Company paid a total of $100 million and received approximately 3.3 million shares.
In August 2019, the Company entered into an accelerated share repurchase agreement under the January 2019 program. Under this accelerated share repurchase agreement, the Company made a prepayment of $250 million to a financial institution and settlement occurred in September 2019. At settlement, the Company received approximately 11.5 million shares, calculated based on the volume-weighted average price of the Company’s common stock over the term of the agreement, less a discount.
Dividend Increase
On February 16, 2022, the Company's Board of Directors authorized a 7% increase in the quarterly cash dividend to $0.10 per common share effective March 2022.

Holders of common stock are entitled to one vote on all matters requiring a vote for each share held. Preferred stock is senior to common stock with respect to dividends and upon liquidation of CSX.
Other Capital
As a result of the stock split during second quarter 2021, CSX's common stock balance was increased and its other capital balance was reduced commensurately. Because this adjustment brought the other capital balance below zero, $1.0 billion was reclassified from retained earnings to other capital to bring the other capital balance to zero as of June 30, 2021. Prior period amounts have also been retroactively adjusted as needed to bring the other capital balance to zero.

NOTE 4. Stock Plans and Share-Based Compensation
Under CSX's share-based compensation plans, awards consist of performance units, stock options, restricted stock units and restricted stock awards for management and stock grants for directors. Awards granted under the various programs are determined and approved by the Compensation and Talent Management Committee of the Board of Directors. Awards to the Chief Executive Officer are approved by the full Board and awards to senior executives are approved by the Compensation and Talent Management Committee. In certain circumstances, the Chief Executive Officer or delegate approves awards to management employees other than senior executives. The Board of Directors approves awards granted to CSX's non-management directors upon recommendation of the Governance and Sustainability Committee.
Share-based compensation expense for awards under share-based compensation plans and purchases made as part of the employee stock purchase plan is measured using the fair value of the award on the grant date and is recognized on a straight-line basis over the service period of the respective award. Alternately, expense is recognized upon death or upon grant date to certain retirement-eligible employees whose agreements allow for continued vesting upon retirement. Forfeitures are recognized as they occur. Total pre-tax expense and income tax benefits associated with share-based compensation are shown in the table below. Income tax benefits include impacts from option exercises and the vesting of other equity awards.

Long-term Incentive Plans
The objective of the CSX Long-term Incentive Plans (“LTIP”) is to motivate and reward certain employees for achieving and exceeding certain financial goals. The 2021-2023 and 2020-2022 LTIP were adopted under the 2019 Stock and Incentive Award Plan and the 2019-2021 LTIP was adopted under the 2010 Stock and Incentive Award Plan. Grants were made in performance units, with each unit being equivalent to one share of CSX common stock, and payouts will be made in CSX common stock. The payout range for most participants will be between 0% and 200% of the target awards depending on Company performance against predetermined goals for each three-year cycle.

Item 8. Financial Statements and Supplementary Data
NOTE 4. Stock Plans and Share-Based Compensation, continued
In 2021, 2020, and 2019, target performance units were granted to certain employees under three separate LTIP plans covering three-year cycles: the 2021-2023 ("2021-2023 LTIP"), the 2020-2022 ("2020-2022 LTIP") and the 2019-2021 (“2019-2021 LTIP”) plans. Payouts of performance units for the plans will be based on the achievement of certain goals, in each case excluding non-recurring items as disclosed in the Company’s financial statements.
•For the 2021-2023 LTIP plan, the average annual operating income growth percentage and cumulative free cash flow over the plan period will each comprise 50% of the payout and will be measured independently of the other. Participants will receive stock dividend equivalents declared over the performance period based on the number of performance units paid upon vesting.
•For the 2020-2022 LTIP plan, the cumulative operating income and cumulative free cash flow over the plan period will each comprise 50% of the payout and will be measured independently of the other. Participants will receive stock dividend equivalents declared over the performance period based on the number of performance units paid upon vesting.
•For the 2019-2021 LTIP plan, the cumulative operating ratio and cumulative free cash flow over the plan period will each comprise 50% of the payout and will be measured independently of the other.
For these plans, payouts for certain executive officers are subject to formulaic upward or downward adjustment by up to 25%, capped at an overall payout of 250%, based upon the Company’s total shareholder return relative to specified comparable groups over the performance period.
The fair values of the performance units awarded during the years ended December 2021, 2020 and 2019 were calculated primarily using a Monte-Carlo simulation model with the following weighted-average assumptions:

Weighted-average assumptions used: | 2021 | 2020 | 2019
Annual dividend yield | n/a | n/a | 1.4 | %
Risk-free interest rate | 0.2 | % | 1.4 | % | 2.4 | %
Annualized volatility | 33.6 | % | 24.5 | % | 27.4 | %
Expected life (in years) | 2.9 | 2.9 | 2.8

Weighted-average grant date fair value | $ | 30.11 |  |  | $ | 25.39 |  |  | $ | 22.06 |

Unvested at December 31, 2021 | 1,576 |  |  | $ | 27.21 |

As of December 2021, there was $20 million of total unrecognized compensation cost related to performance units that is expected to be recognized over a weighted-average period of approximately two years.
Stock Options
Stock options in 2021, 2020, and 2019 were primarily granted along with the corresponding LTIP plans. Under this program, an employee receives an award that provides the opportunity in the future to purchase CSX shares at the closing market price of the stock on the date the award is granted (the strike price). Options granted become exercisable in equal installments on the anniversary of the grant date over a vesting period (three-year graded). All options expire 10 years from the grant date if they are not exercised.
The fair value of stock options granted was estimated as of the dates of grant using the Black-Scholes option valuation model, which uses the following assumptions: dividend yield, risk-free interest rate, annualized volatility and expected life. The annual dividend yield is based on the most recent quarterly CSX dividend payment annualized. The risk-free interest rate is based on U.S. Treasury yield curve in effect at the time of grant. The annualized volatility is based on historical volatility of daily CSX stock price returns over a 6.0 year look-back period ending on the grant date. The expected life is calculated using the safe harbor approach due to lack of historical data on CSX options, which is the midpoint between the vesting schedule and contractual term (10 years).
Assumptions and inputs used to estimate fair value of stock options are summarized as follows:

| Fiscal Years
| 2021 | 2020 | 2019
Weighted-average grant date fair value | $ | 7.94 |  | $ | 6.31 |  | $ | 5.96 |

Annual dividend yield | 1.2 | % | 1.2 | % | 1.3 | %
Risk-free interest rate | 0.7 | % | 1.4 | % | 2.4 | %
Annualized volatility | 31.2 | % | 26.1 | % | 25.7 | %

Stock Awards for Directors
CSX’s non-management directors receive a base annual retainer of $122,500 to be paid quarterly in cash, unless the director chooses to defer the retainer in the form of cash or CSX common stock. Additionally, non-management directors receive an annual grant of common stock in the amount of approximately $172,500, with the number of shares to be granted based on the average closing price of CSX stock in the months of November, December and January. The independent non-executive Chairman also receives an annual grant of common stock in the amount of approximately $250,000, with the number of shares to be granted based on the average closing price of CSX stock in the months of November, December, and January. These awards are evaluated periodically by the Board of Directors.
Employee Stock Purchase Plan
In May 2018, shareholders approved the 2018 CSX Employee Stock Purchase Plan (“ESPP”) for the benefit of Company employees. The Company registered 12 million (split-adjusted) shares of common stock that may be issued pursuant to this plan. Under the ESPP, employees may contribute between 1% and 10% of base compensation, after-tax, to purchase up to $25,000 of market value CSX common stock per year at 85% of the closing market price on either the grant date or the last day of the six-month offering period, whichever is lower.

These liabilities are accrued when probable and reasonably estimable in accordance with the Contingencies Topic in the ASC. Actual settlements and claims received could differ and final outcomes of these matters cannot be predicted with certainty. Considering the legal defenses currently available, the liabilities that have been recorded and other factors, it is the opinion of management that none of these items individually, when finally resolved, will have a material adverse effect on the Company's financial condition, results of operations or liquidity. Should a number of these items occur in the same period, however, their combined effect could be material in that particular period.
Casualty
Casualty reserves of $180 million and $196 million for 2021 and 2020, respectively, represent accruals for personal injury, occupational disease and occupational injury claims primarily related to railroad operations. Beginning June 1, 2021, the Company's self-insured retention amount for these claims increased from $75 million to $100 million per occurrence. Currently, no individual claim is expected to exceed the self-insured retention amount. Most of the Company's casualty claims relate to CSXT. In accordance with the Contingencies Topic in the ASC, to the extent the value of an individual claim exceeds the self-insured retention amount, the Company would present the liability on a gross basis with a corresponding receivable for insurance recoveries.
These reserves fluctuate based upon the timing of payments as well as changes in estimate. Actual results may vary from estimates due to the number, type and severity of the injury, costs of medical treatments and uncertainties in litigation. Defense and processing costs, which historically have been insignificant and are anticipated to be insignificant in the future, are not included in the recorded liabilities. Changes in casualty reserves are included in purchased services and other on the consolidated income statements.
Personal Injury
Personal injury reserves represent liabilities for employee work-related and third-party injuries. Work-related injuries for CSXT employees are primarily subject to the Federal Employers' Liability Act ("FELA"). CSXT retains an independent actuary to assist management in assessing the value of personal injury claims. An analysis is performed by the actuary quarterly and is reviewed by management. The methodology used by the actuary includes a development factor to reflect growth or reduction in the value of these personal injury claims based largely on CSXT's historical claims and settlement experience. These analyses did not result in a material adjustment to the personal injury reserve in 2021, 2020 or 2019.

Occupational
Occupational reserves represent liabilities arising from allegations of exposure to certain materials in the workplace (such as solvents, soaps, chemicals and diesel fumes), past exposure to asbestos or allegations of chronic physical injuries resulting from work conditions (such as repetitive stress injuries). Beginning in second quarter 2020, the Company retains an independent actuary to analyze the Company’s historical claims, settlement amounts, and dismissal rates to assist in determining future anticipated claim filing rates and average settlement values. This analysis is performed by the actuary and reviewed by management quarterly. Previously, the quarterly analysis was performed by management. There were no material adjustments to the occupational reserve in 2021, 2020 or 2019.
Environmental
Environmental reserves were $108 million and $76 million for 2021 and 2020, respectively. Environmental reserves as of December 31, 2021, include liabilities assumed as a result of the Company's acquisition of Quality Carriers. The Company is a party to various proceedings related to environmental issues, including administrative and judicial proceedings involving private parties and regulatory agencies. The Company has been identified as a potentially responsible party at approximately 220 environmentally impaired sites. Many of these are, or may be, subject to remedial action under the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), also known as the Superfund Law, or similar state statutes. Most of these proceedings arose from environmental conditions on properties used for ongoing or discontinued railroad operations. A number of these proceedings, however, are based on allegations that the Company, or its predecessors, sent hazardous substances to facilities owned or operated by others for treatment, recycling or disposal. In addition, some of the Company’s land holdings were leased to others for commercial or industrial uses that may have resulted in releases of hazardous substances or other regulated materials onto the property and could give rise to proceedings against the Company.
In any such proceedings, the Company is subject to environmental clean-up and enforcement actions under the Superfund Law, as well as similar state laws that may impose joint and several liability for clean-up and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. These costs could be substantial.

In accordance with the Asset Retirement and Environmental Obligations Topic in the ASC, the Company reviews its role with respect to each site identified at least quarterly, giving consideration to a number of factors such as:
•type of clean-up required;
•nature of the Company’s alleged connection to the location (e.g., generator of waste sent to the site or owner or operator of the site);
•extent of the Company’s alleged connection (e.g., volume of waste sent to the location and other relevant factors); and
•number, connection and financial viability of other named and unnamed potentially responsible parties at the location.
Based on management's review process, amounts have been recorded to cover contingent anticipated future environmental remediation costs with respect to each site to the extent such costs are reasonably estimable and probable. The recorded liabilities for estimated future environmental costs are undiscounted. The liability includes future costs for remediation and restoration of sites as well as any significant ongoing monitoring costs, but excludes any anticipated insurance recoveries. Payments related to these liabilities are expected to be made over the next several years. Environmental remediation costs are included in purchased services and other on the consolidated income statements.
Currently, the Company does not possess sufficient information to reasonably estimate the amounts of additional liabilities, if any, on some sites until completion of future environmental studies. In addition, conditions that are currently unknown could, at any given location, result in additional exposure, the amount and materiality of which cannot presently be reasonably estimated. Based upon information currently available, however, the Company believes its environmental reserves accurately reflect the estimated cost of remedial actions currently required.
Other
Other reserves were $80 million and $42 million for 2021 and 2020, respectively. These reserves as of December 31, 2021, include liabilities assumed as a result of the Company's acquisition of Quality Carriers. Other reserves include liabilities for various claims, such as automobile, property, general liability and workers' compensation. Also included in other reserves are longshoremen disability claims related to a previously owned international shipping business (these claims are in runoff) as well as claims for current port employees.

Capital Expenditures
The Company’s capital investment includes purchased and self-constructed assets and property additions that substantially extend the service life or increase the utility of those assets. Indirect costs that can be specifically traced to capital projects are also capitalized. The Company is committed to maintaining and improving its existing infrastructure and expanding its network capacity for long-term growth. Rail operations are capital intensive and CSX accounts for these costs in accordance with GAAP and the Company’s capitalization policy. All properties are stated at historical cost less an allowance for accumulated depreciation.
The Company’s largest category of capital investment is the replacement of track assets and the acquisition or construction of new assets that enable CSX to enhance its operations or provide new capacity offerings to its customers. These construction projects are primarily completed by CSXT employees. Costs for track asset replacement and capacity projects that are capitalized include:
•labor costs, because many of the assets are self-constructed;
•costs to purchase or construct new track or to prepare ground for the laying of track;
•welding (rail, field and plant), which are processes used to connect segments of rail;
•new ballast, which is gravel and crushed stone that holds track in line;
•fuels and lubricants associated with tie, rail and surfacing work, which is the process of raising track to a designated elevation over an extended distance;
•cross, switch and bridge ties, which are the braces that support the rails on a track;
•gauging, which is the process of standardizing the distance between rails;
•handling costs associated with installing rail, ties or ballast;
•usage charge of machinery and equipment utilized in construction or installation; and
•other track materials.
Labor is a significant cost in self-constructed track replacement work. CSXT engineering employees directly charge their labor to the track replacement project (the capitalized depreciable property). In replacing track, these employees concurrently perform deconstruction and installation of track material. Because of this concurrent process, CSX must estimate the amount of labor that is related to deconstruction versus installation. As a component of the depreciation study for road and track assets, management performs an analysis of labor costs related to the self-constructed track replacement work, which includes direct observation of track replacement processes. Through this analysis, CSX determined that approximately 20% of labor costs associated with track replacement is related to the deconstruction of old track, for which certain elements are expensed, and 80% is associated with the installation of new track, which is capitalized.
Capital investment related to locomotives and freight cars comprises the second largest category of the Company’s capital assets. This category includes purchases of locomotives and freight cars as well as certain equipment leases that are considered to be finance leases in accordance with the Leases Topic in the ASC. In addition, costs to modify or rebuild these assets are capitalized if the investment incurred extends the asset’s service life or improves utilization. Improvement projects must meet specified dollar thresholds to be capitalized and are reviewed by management to determine proper accounting treatment. Routine repairs, overhauls and other maintenance costs, for all asset categories, are expensed as incurred.

Depreciation Method
The depreciable assets of the Company are depreciated using either the group-life or straight-line method of accounting, which are both acceptable depreciation methods in accordance with GAAP. The Company depreciates its railroad assets, including main-line track, locomotives and freight cars, using the group-life method. Assets depreciated under the group-life method comprise 86% of total fixed assets of $46.5 billion on a gross basis as of December 2021. The remaining depreciable assets of the Company, including non-railroad assets and assets under finance leases, are depreciated using the straight-line method on a per asset basis. Land is not depreciated.
The group-life method aggregates assets with similar lives and characteristics into groups and depreciates each of these groups as a whole. When using the group-life method, an underlying assumption is that each group of assets, as a whole, is used and depreciated to the end of its group’s recoverable life. The Company currently utilizes different depreciable asset categories to account for depreciation expense for the railroad assets that are depreciated under the group-life method. By utilizing various depreciable categories, the Company can more accurately account for the use of its assets. All assets of the Company are depreciated on a time or life basis.
The group-life method of depreciation closely approximates the straight-line method of depreciation. Additionally, due to the nature of most of its assets (e.g. track is one contiguous, connected asset), the Company believes that this is the most accurate and effective way to properly depreciate its assets.
Estimated Useful Life
Management performs a review of depreciation expense and useful lives on a regular basis. Under the group-life method, the service lives and salvage values for each group of assets are determined by completing periodic depreciation studies and applying management’s methods to determine the service lives of its properties. A depreciation study is the periodic review of asset service lives, salvage values, accumulated depreciation, and other related factors for group assets conducted by a third-party specialist, analyzed by the Company’s management and approved by the STB, the regulatory board that has broad jurisdiction over railroad practices. The STB requires depreciation studies be performed every three years for equipment assets (e.g., locomotives and freight cars) and every six years for road and track assets (e.g., bridges, signals, rail, ties, and ballast). The Company believes the frequency of depreciation studies currently required by the STB, complemented by annual data reviews conducted by a third-party specialist and analyzed by the Company's management, provides adequate review of asset service lives and that a more frequent review would not result in a material change due to the long-lived nature of most of the assets.
The Company completed a depreciation study for its road and track assets in 2020 and for equipment assets in 2019, both of which resulted in changes to accumulated depreciation, service lives, salvage values, and other related factors for certain assets. Recent experience with depreciation studies has resulted in changes to accumulated depreciation and depreciation rates that did not materially affect the Company's depreciation expense of $1.4 billion, $1.4 billion and $1.3 billion for 2021, 2020 and 2019, respectively.

Group-Life Assets Sales and Retirements
Since the rail network is one contiguous, connected network it is impractical to maintain specific identification records for these assets. For track assets (e.g., rail, ties, and ballast), CSX utilizes a first-in, first-out approach to asset retirements. Equipment assets (e.g., locomotives and freight cars) are specifically identified at retirement. When an equipment asset is retired that has been depreciated using the group-life method, the cost is reduced from the cost base and recorded in accumulated depreciation.
For sales or retirements of assets depreciated under the group-life method that occur in the ordinary course of business, the asset cost (net of salvage value or sales proceeds) is charged to accumulated depreciation and no gain or loss is immediately recognized. This practice is consistent with accounting treatment prescribed under the group-life method. As part of the depreciation study, an assessment of the recorded amount of accumulated depreciation is made to determine if it is deficient (or in excess) of the appropriate amount indicated by the study. Any such deficiency (or excess), including any deferred gains or losses, is amortized as a component of depreciation expense over the remaining service life of the asset group until the next required depreciation study. Since the overall assumption with the group-life method is that the assets within the group on average have the same service life and characteristics, it is therefore concluded that the deferred gains and losses offset over time.
For sales or retirements of assets depreciated under the group-life method that do not occur in the ordinary course of business, a gain or loss may be recognized if the sale or retirement meets each of the following three criteria: (i) it is unusual, (ii) it is material in amount, and (iii) it varies significantly from the retirement profile identified through our depreciation studies. No material gains or losses were recognized on the sale of assets depreciated using the group-life method in 2021, 2020 or 2019, as no sales met the criteria described above.
Land and Straight-line Assets Sales and Retirements
When the Company sells or retires land, land-related easements or assets depreciated under the straight-line method, a gain or loss is recognized in purchased services and other on the consolidated statements of income. Primarily as a result of its initiative to monetize non-core properties, the Company recognized gains on the sale of properties of $454 million, $35 million and $151 million in 2021, 2020 and 2019, respectively.
Sale of Property Rights to the Commonwealth of Virginia
On March 26, 2021, the Company entered into a comprehensive agreement to sell certain property rights in three CSX-owned line segments to the Commonwealth of Virginia (“Commonwealth”) over three phases for a total of $525 million. The timing and amount of gains recognized are based on the allocation of fair value to each conveyance, the timing of future conveyances and collectability. In April 2021, upon closing of the first phase of the agreement, the Company collected $200 million in proceeds and recognized a $349 million gain. In fourth quarter 2021, the Company collected additional proceeds of $200 million, a portion of which was attributable to the first phase with the remaining attributable to the second phase. There was no gain recognized in fourth quarter 2021 related to this agreement. As the second phase closed on January 10, 2022, the resulting $20 million gain will be recognized in first quarter 2022.
The Company anticipates closing on the remaining conveyances by the end of 2022, which will result in future cash proceeds and gains. As of December 31, 2021, the carrying values of the remaining assets subject to this transaction were not material.

Impairment Review
Properties and other long-lived assets are reviewed for impairment whenever events or business conditions indicate the carrying amount of such assets may not be fully recoverable. Initial assessments of recoverability are based on estimates of undiscounted future net cash flows associated with an asset or a group of assets in accordance with the Property, Plant, and Equipment Topic in the ASC. Where impairment is indicated, the assets are evaluated and their carrying amount is reduced to fair value based on discounted net cash flows or other estimates of fair value. Impairment expense of $2 million in 2021 and $8 million in 2020 was primarily due to the discontinuation of certain in-progress projects. In 2019, impairment expense of $22 million was related to an intermodal terminal sale agreement. Impairment expense is recorded in purchased services and other expense on the consolidated income statement.
NOTE 7. Leases
At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of the Company’s lease arrangements contain lease components (e.g., minimum rent payments) and non-lease components (e.g., maintenance, labor charges, etc.). The Company generally accounts for each component separately based on the estimated standalone price of each component. For certain equipment leases, such as freight car, vehicles and work equipment, the Company accounts for the lease and non-lease components as a single lease component.
Certain of the Company’s lease agreements include rental payments that are adjusted periodically for an index or rate. The leases are initially measured using the projected payments adjusted for the index or rate in effect at the commencement date. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Operating Leases
Operating leases are included in right-of-use lease assets, other current liabilities and long-term lease liabilities on the consolidated balance sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term using the Company’s secured incremental borrowing rates or implicit rates, when readily determinable. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet.
The Company has various lease agreements with other parties with terms up to 50 years. Non-cancelable, long-term leases may include provisions for maintenance, options to purchase and options to extend the terms. These options are included in the lease term when it is reasonably certain that the option will be exercised. Lease expense for operating leases, including leases with escalations over their terms, is recognized on a straight-line basis over the lease term. Variable lease expense is recognized in the period in which the obligation for those payments is incurred. Lease expense is included in equipment and other rents on the consolidated income statements and is reported net of lease income. Lease income was not material to the results of operations for 2021, 2020 or 2019.

NOTE 8. Commitments and Contingencies
Purchase Commitments
CSXT's long-term locomotive maintenance program agreement with a third party contains commitments related to specific locomotive rebuilds and a long-term maintenance program that covers a portion of CSXT’s fleet of locomotives. The maintenance program costs are based on the maintenance cycle for each covered locomotive, which is determined by the asset's age and type. Expected future costs may change as required maintenance schedules are revised and locomotives are placed into or removed from service. Under CSXT’s current obligations, the agreement will expire no earlier than 2035.
The following table summarizes the number of locomotives covered and CSXT’s payments under the long-term maintenance program.

Insurance
The Company maintains insurance programs with substantial limits for property damage, including resulting business interruption, and third-party liability. A certain amount of risk is retained by the Company on each insurance program. Under its property insurance program, the Company retains all risk up to $100 million per occurrence for losses from floods and named windstorms and up to $75 million per occurrence for other property losses. For third-party liability claims, the Company retains all risk up to $100 million per occurrence. As CSX negotiates insurance coverage above its full self-retention amounts, it retains a percentage of risk at various layers of coverage. While the Company believes its insurance coverage is adequate, future claims could exceed existing insurance coverage or insurance may not continue to be available at commercially reasonable rates.
Legal
The Company is involved in litigation incidental to its business and is a party to a number of legal actions and claims, various governmental proceedings and private civil lawsuits, including, but not limited to, those related to fuel surcharge practices, tax matters, environmental and hazardous material exposure matters, FELA and labor claims by current or former employees, other personal injury or property claims and disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for compensatory as well as punitive damages and others are, or are purported to be, class actions. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the legal defenses available and liabilities that have been recorded along with applicable insurance, it is currently the opinion of management that none of these pending items will have a material adverse effect on the Company's financial condition, results of operations or liquidity. An unexpected adverse resolution of one or more of these items, however, could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.

The Company is able to estimate a range of possible loss for certain legal proceedings for which a loss is reasonably possible in excess of reserves established. The Company has estimated this range to be $2 million to $25 million in aggregate as of December 31, 2021. This estimated aggregate range is based upon currently available information and is subject to significant judgment and a variety of assumptions. Accordingly, the Company's estimate will change from time to time, and actual losses may vary significantly from the current estimate.
Fuel Surcharge Antitrust Litigation
In May 2007, class action lawsuits were filed against CSXT and three other U.S.-based Class I railroads alleging that the defendants' fuel surcharge practices relating to contract and unregulated traffic resulted from an illegal conspiracy in violation of antitrust laws. The class action lawsuits were consolidated into one case in federal court in the District of Columbia. In 2017, the District Court issued its decision denying class certification. On August 16, 2019, the U.S. Court of Appeals for the D.C. Circuit affirmed the District Court’s ruling.
The consolidated case is now moving forward without class certification. Although a class was not certified, shippers other than those who brought the original lawsuit in 2007 must decide whether to bring their own individual claim against one or more railroads. Individual shipper claims filed to date have been consolidated into a separate case.
CSXT believes that its fuel surcharge practices were arrived at and applied lawfully and that the case is without merit. Accordingly, the Company intends to defend itself vigorously. However, penalties for violating antitrust laws can be severe, and resolution of these matters individually or when aggregated could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.

CSXT is indemnifying Pharmacia LLC, formerly known as Monsanto Company, ("Pharmacia") for certain liabilities associated with real estate located in Kearny, New Jersey along the Lower Passaic River (the “Property”). The Property, which was formerly owned by Pharmacia, is now owned by CSXT. CSXT's indemnification and defense duties arise with respect to several matters. The U.S. Environmental Protection Agency ("EPA"), using its CERCLA authority, seeks the investigation and cleanup of hazardous substances in the 17-mile Lower Passaic River Study Area (the "Study Area”). CSXT, on behalf of Pharmacia, and a significant number of other potentially responsible parties are together conducting a Remedial Investigation and Feasibility Study of the Study Area pursuant to an Administrative Settlement Agreement and Order on Consent with the EPA. Pharmacia’s share of responsibility, indemnified by CSXT, for the investigation and cleanup costs of the Study Area may be determined through various mechanisms including (a) an allocation and settlement with EPA; (b) litigation brought by EPA against non-settling parties; or (c) litigation among the responsible parties.
In March 2016, EPA issued its Record of Decision detailing the agency’s mandated remedial process for the lower 8 miles of the Study Area. Approximately 80 parties, including Pharmacia, are participating in an EPA-directed allocation and settlement process to assign responsibility for the remedy selected for the lower 8 miles of the Study Area. CSXT is participating in the EPA-directed allocation and settlement process on behalf of Pharmacia. EPA has also selected an interim remedy for the remainder of the Study Area in a Record of Decision dated September 28, 2021. Settlement discussions are also ongoing for the selected interim remedy.
CSXT is also defending and indemnifying Pharmacia with regard to the Property in litigation filed by Occidental Chemical Corporation, which is seeking to recover various costs. These costs include costs for the remedial design of the lower 8 miles of the Study Area, as well as anticipated costs associated with the future remediation of the lower 8 miles of the Study Area and potentially the entire Study Area. Alternatively, Occidental seeks to compel some, or all of the defendants to participate in the remediation of the Study Area. Pharmacia is one of approximately 110 defendants in this federal lawsuit filed by Occidental on June 30, 2018.
CSXT is also defending and indemnifying Pharmacia in a cooperative natural resource damages assessment process related to the Property. Based on currently available information, the Company does not believe any indemnification or remediation costs potentially allocable to CSXT with respect to the Property and the Study Area would be material to the Company's financial condition, results of operations or liquidity.

NOTE 9. Employee Benefit Plans
The Company sponsors defined benefit pension plans principally for salaried, management personnel. For employees hired prior to 2003, the plans provide eligible employees with retirement benefits based predominantly on years of service and compensation rates near retirement. For employees hired between 2003 and 2019, benefits are determined based on a cash balance formula, which provides benefits by utilizing interest and pay credits based upon age, service and compensation. Beginning in 2020, the CSX Pension Plan was closed to new participants.
In addition to these plans, the Company sponsors a post-retirement medical plan and a life insurance plan that provide certain benefits to full-time, salaried, management employees hired prior to 2003 upon their retirement if certain eligibility requirements are met. Beginning in 2019, both the life insurance benefit for eligible active management employees and health savings account contributions made by the Company to eligible retirees younger than 65 were eliminated for those retiring on or after January 1, 2019. Beginning in 2020, the employer-funded health reimbursement arrangements and life insurance benefit for eligible retirees 65 years or older were eliminated. These changes did not result in a curtailment loss as there was no material impact to service costs for active plan participants.
The Company engages independent actuaries to compute the amounts of liabilities and expenses relating to these plans subject to the assumptions that the Company determines are appropriate based on historical trends, current market rates and future projections. These amounts are reviewed by management. In order to perform this valuation, the actuaries are provided with the details of the population covered at the beginning of the year, summarized in the table below, and projects that population forward to the end of the year.

The benefit obligation for these plans represents the liability of the Company for current and retired employees and is affected primarily by the following:
•service cost (benefits attributed to employee service during the period);
•interest cost (interest on the liability due to the passage of time);
•actuarial gains/losses (experience during the year different from that assumed and changes in plan assumptions); and
•benefits paid to participants.
Cash Flows
Plan assets are amounts that have been segregated and restricted to provide qualified pension plan benefits and include amounts contributed by the Company and amounts earned from invested contributions, net of benefits paid. Qualified pension plan obligations are funded in accordance with regulatory requirements and with an objective of meeting or exceeding minimum funding requirements necessary to avoid restrictions on flexibility of plan operation and benefit payments. The Company funds the cost of the post-retirement medical and life insurance benefits as well as nonqualified pension benefits on a pay-as-you-go basis. No qualified pension plan contributions were made during 2021, 2020 and 2019. No contributions to the Company's qualified pension plans are expected in 2022.
Future expected benefit payments are as follows:

Plan Assets
During 2020, the Company migrated to an outsourced investment management strategy to manage the pension plan assets. The CSX Investment Committee (the “Investment Committee”), whose members are selected by the Executive Vice President and Chief Financial Officer, is responsible for setting policy and oversight of investment management. The Investment Committee and investment manager utilize an investment asset allocation strategy that is monitored on an ongoing basis and updated periodically in consideration of plan or employee changes, or changing market conditions. Periodic studies provide an extensive modeling of asset investment return in conjunction with projected plan liabilities and seek to evaluate how to maximize return within the constraints of acceptable risk.

Under the supervision of the Investment Committee, the investment manager selects investments or fund managers in accordance with standards of prudence applicable to asset diversification and investment suitability. The Company also selects fund managers with differing investment styles and benchmarks their investment returns against appropriate indices. Fund investment performance is continuously monitored. Acceptable performance is determined in the context of the long-term return objectives of the fund and appropriate asset class benchmarks.
Within the Company's equity funds, domestic stock is diversified among large and small capitalization stocks. International stock is diversified in a similar manner as well as in developed versus emerging markets stocks. Guidelines established with individual managers limit investment by industry sectors, individual stock issuer concentration and the use of derivatives and CSX securities.
Fixed income securities guidelines established with individual managers specify the types of allowable investments, such as government, corporate and asset-backed bonds, target certain allocation ranges for domestic and foreign investments and limit the use of certain derivatives. Additionally, guidelines stipulate minimum credit quality constraints and any prohibited securities.

For qualified plan funding purposes, assets and discounted liabilities are measured in accordance with the Employee Retirement Income Security Act ("ERISA"), as well as other related provisions of the Internal Revenue Code and related regulations. Under these funding provisions and the alternative measurements available thereunder, the Company estimates its unfunded obligation for qualified plans on an annual basis.
In accordance with Compensation-Retirement Benefits Topic in the ASC, an employer must recognize the funded status of a pension or other post-retirement benefit plan by recording a liability (underfunded plan) or asset (overfunded plan) for the difference between the projected benefit obligation (or the accumulated post-retirement benefit obligation for a post-retirement benefit plan) and the fair value of plan assets at the plan measurement date.

Assumptions
The expected long-term average rate of return on plan assets reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for benefits included in the projected benefit obligation. In estimating that rate, the Company gives appropriate consideration to the returns being earned by the plan assets in the funds and the rates of return expected to be available for reinvestment as well as the current and projected asset mix of the funds. Management, with the assistance of the outsourced investment manager, balances market expectations obtained from various investment managers with both market and actual plan historical returns to develop a reasonable estimate of the expected long-term rate of return on assets. This assumption is reviewed annually and adjusted as deemed appropriate.
The Company measures the service cost and interest cost components of the net pension and post-retirement benefits expense by using individual spot rates matched with separate cash flows for each future year. The weighted averages of assumptions used by the Company to value its pension and post-retirement obligations were as follows:

| Pension Benefits |  | Post-retirement Benefits
| 2021 |  | 2020 |  | 2021 |  | 2020
Expected Long-term Return on Plan Assets: |  |  |  |  |  |  |

Other Plans
Under collective bargaining agreements, the Company participates in a multi-employer benefit plan, which provides certain post-retirement health care and life insurance benefits to eligible contract employees. Premiums under this plan are expensed as incurred and amounted to $21 million, $20 million and $26 million in 2021, 2020 and 2019, respectively.
The Company maintains savings plans for virtually all full-time salaried employees and certain employees covered by collective bargaining agreements. Expense associated with these plans was $29 million, $39 million and $41 million for 2021, 2020 and 2019, respectively, and is included in labor and fringe expense on the consolidated income statement.
Under the terms of collective bargaining agreements that cover union-represented employees, Quality Carriers contributes to three multi-employer pension plans. These plans provide defined benefits to retired participants. All three of these pension plans are in Pension Protection Act zone “red”, meaning they are at least 65% underfunded. Formal rehabilitation plans have been adopted. As of December 31, 2021, based on information provided to the Company from the administrators of these plans, Quality Carriers’ portion of the contingent liability in the case of a full withdrawal or termination from these plans is approximately $334 million, of which $323 million relates to the Central States Southeast and Southwest Areas Pension Plan. The Company does not currently intend to withdraw from any of these multi-employer pension plans. Required monthly contributions to these plans are not material.

Debt Issuance & Early Redemption of Long-term Debt
No debt was issued in 2021. CSX issued the following notes in 2020, which are included in the consolidated balance sheets under long-term debt and may be redeemed by the Company at any time, subject to payment of certain make-whole premiums:
•On December 1, 2020, issued $500 million of 2.50% notes due 2051. On December 30, 2020, the proceeds of the offering were used to fully redeem CSX’s outstanding $500 million of 3.70% notes that otherwise would have matured on November 1, 2023.
•On March 30, 2020, issued $500 million of 3.8% notes due 2050.
The net proceeds from debt issuances will be used for general corporate purposes, which may include debt repayments, repurchases of CSX's common stock, capital investment, working capital requirements, improvements in productivity and other cost reductions. For more information regarding a non-cash debt transaction with a related party, see Note 15, Investment in Affiliates and Related-Party Transactions.

Interest Rate Derivatives
On both April 29, 2020, and July 9, 2020, the Company executed a forward starting interest rate swap with a notional value of $250 million for an aggregate notional value of $500 million. These swaps were effected to hedge the benchmark interest rate associated with future interest payments related to the anticipated refinancing of $850 million of 3.25% notes due in 2027. In accordance with the Derivatives and Hedging Topic in the ASC, the Company has designated these swaps as cash flow hedges. As of December 31, 2021 and 2020, the asset value of the forward starting interest rate swaps was $91 million and $80 million, respectively, and was recorded in other long-term assets on the consolidated balance sheet.
Unrealized gains or losses associated with changes in the fair value of the hedge are recorded net of tax in accumulated other comprehensive income (“AOCI”) on the consolidated balance sheet. Unless settled early, the swaps will expire in 2027 and the unrealized gain or loss in AOCI will be recognized in earnings as an adjustment to interest expense over the same period during which the hedged transaction affects earnings. Unrealized gains, recorded net of tax in other comprehensive income, related to the hedges were $8 million and $62 million for the years ended December 31, 2021 and 2020, respectively.
Credit Facilities
CSX has a $1.2 billion unsecured, revolving credit facility backed by a diverse syndicate of banks. This facility allows same-day borrowings at floating interest rates, based on LIBOR or an agreed-upon replacement reference rate, plus a spread that depends upon CSX's senior unsecured debt ratings. This facility expires in March 2024, and as of December 31, 2021, the Company had no outstanding balances under this facility.
Commitment fees and interest rates payable under the facility were similar to fees and rates available to comparably rated investment-grade borrowers. As of December 31, 2021, CSX was in compliance with all covenant requirements under the facility.
Commercial Paper
Under its commercial paper program, which is backed by the revolving credit facility, the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount of $1.0 billion. Proceeds from issuances of the notes are expected to be used for general corporate purposes. At December 31, 2021, the Company had no commercial paper outstanding.

(a) Effective first quarter 2021, changes were made in the categorization of certain lines of business, impacting Forest Products and Fertilizers. The impacts were not material and prior periods have been reclassified to conform to the current presentation.
(b) Effective third quarter 2021, Trucking revenue is comprised of revenue from the operations of Quality Carriers, which was acquired by CSX effective July 1, 2021.
Revenue Recognition
The Company generates revenue from rail freight billings under contracts with customers generally on a rate per carload, container or ton-basis based on length of haul and commodities carried. The Company’s performance obligation arises when it receives a bill of lading (“BOL”) to transport a customer's commodities at a negotiated price contained in a transportation services agreement or a publicly disclosed tariff rate. Once a BOL is received, a contract is formed whereby the parties are committed to perform, collectability of consideration is probable and the rights of the parties, shipping terms and conditions, and payment terms are identified. A customer may submit several BOLs for transportation services at various times throughout a service agreement term, but each shipment represents a distinct service that is a separately identified performance obligation.
CSX 2021 Form 10-K p.93

CSX CORPORATION
PART II
Item 8. Financial Statements and Supplementary Data
NOTE 11. Revenues, continued
The average transit time to complete a rail shipment is between 2 to 8 days depending on market. Payments for transportation services are normally billed once a BOL is received and are generally due within 15 days after the invoice date. The Company recognizes revenue over transit time of freight as it moves from origin to destination. Revenue for services started but not completed at the reporting date is allocated based on the relative transit time in each reporting period, with the portion allocated for services subsequent to the reporting date considered remaining performance obligations.
The certain key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:
•Revenue associated with shipments in transit is recognized ratably over transit time and is based on average cycle times to move commodities and products from their origin to their final destination or interchange;
•Adjustments to revenue for billing corrections and billing discounts;
•Adjustments to revenue for overcharge claims filed by customers, which are based on historical payments to customers for rate overcharges as a percentage of total billing; and
•Incentive-based refunds to customers, which are primarily volume-related, are recorded as a reduction to revenue on the basis of the projected liability (this estimate is based on historical activity, current volume levels and forecasted future volume).
Revenue related to interline transportation services that involve the services of another party, such as another railroad, is reported on a net basis. The portion of the gross amount billed to customers that is remitted by the Company to another party is not reflected as revenue.
Effective third quarter 2021, trucking revenue includes revenue from the operations of Quality Carriers and is mostly comprised of truck shipments of chemicals. A performance obligation arises when Quality Carriers receives a customer order to transport a commodity at a contracted rate. Revenue is recorded on a gross basis ratably over transit time.
Other revenue is recorded upon completion of the service and is comprised of revenue from regional subsidiary railroads and incidental charges, including intermodal storage and equipment usage, demurrage and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.
During 2021, 2020 and 2019, revenue recognized from performance obligations related to prior periods (for example, due to changes in transaction price) was not material.

Remaining Performance Obligations
Remaining performance obligations represent the transaction price allocated to future reporting periods for freight services started but not completed at the reporting date. This includes the unearned portion of billed and unbilled amounts for cancellable freight shipments in transit. The Company expects to recognize the unearned portion of revenue for freight services in transit within one week of the reporting date. As of December 31, 2021, remaining performance obligations were not material.
Contract Balances and Accounts Receivable
The timing of revenue recognition, billings and cash collections results in accounts receivable and customer advances and deposits (contract liabilities) on the consolidated balance sheets. Contract assets, contract liabilities and deferred contract costs recorded on the consolidated balance sheet as of December 31, 2021 were not material.
The Company’s accounts receivable - net consists of freight and non-freight receivables, reduced by an allowance for credit losses.

Non-Freight Receivables, net | 211 |  | 212 |
Total Accounts Receivable, net | $ | 1,148 |  | $ | 912 |

Freight receivables include amounts earned, billed and unbilled, and currently due from customers for transportation-related services. Non-freight receivables include amounts billed and unbilled and currently due related to government reimbursement receivables and other non-revenue receivables. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of risk characteristics, historical payment experience, and the age of outstanding receivables adjusted for forward-looking economic conditions as necessary. Credit losses recognized on the Company’s accounts receivable were not material in 2021 and 2020.

The Company recorded a 2021 income tax benefit of $48 million primarily as a result of favorable state legislative changes, additional tax benefits associated with the vesting of share-based awards and adjustments to deferred taxes as a result of filing the 2020 state tax returns. In 2020, the Company recorded an income tax benefit of $30 million primarily as a result of the additional tax benefit associated with vesting of share-based awards and the resolution of certain tax matters. The Company recorded a 2019 income tax benefit of $77 million primarily as a result of the additional tax benefit associated with vesting of share-based awards, federal and state legislative changes, and a change in the valuation of deferred taxes as a result of filing the 2018 tax returns.

The Company files a consolidated federal income tax return, which includes its principal domestic subsidiaries. CSX and its subsidiaries are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. CSX participated in a contemporaneous IRS audit of tax years 2021 and 2020. Federal examinations of original federal income tax returns for all years through 2019 are resolved.
As of December 2021 and 2020, the Company had approximately $18 million and $16 million, respectively, of total unrecognized tax benefits as a result of uncertain tax positions. Net tax benefits of $15 million and $13 million as of December 2021 and 2020, respectively, could favorably impact the effective income tax rate in each year. The Company does not expect that unrecognized tax benefits as of December 2021 for various state and federal income tax matters will significantly change over the next 12 months. The final outcome of these uncertain tax positions is not yet determinable. There were no material changes to the total gross unrecognized tax benefits and prior year audit resolutions of the Company during the fiscal year ended December 2021.
CSX’s continuing practice is to recognize net interest and penalties related to income tax matters in income tax expense. Accrued interest and penalties were not material as of December 2021 or 2020. Additionally, expenses from changes to the reserves for interest and penalties were not material in 2021, 2020 or 2019.

NOTE 13. Fair Value Measurements
The Financial Instruments Topic in the ASC requires disclosures about fair value of financial instruments in annual reports as well as in quarterly reports. For CSX, this statement applies to certain investments, pension plan assets, long-term debt and interest rate derivatives. Also, the Fair Value Measurements and Disclosures Topic in the ASC clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements.
Various inputs are considered when determining the value of the Company's investments, pension plan assets, long-term debt and interest rate derivatives. The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in these securities. These inputs are summarized in the three broad levels listed below:
•Level 1 – observable market inputs that are unadjusted quoted prices for identical assets or liabilities in active markets;
•Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, credit risk, etc.); and
•Level 3 – significant unobservable inputs (including the Company’s own assumptions about the assumptions market participants would use in determining the fair value of investments).
The valuation methods described below may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
Investments
The Company's investment assets are carried at fair value on the consolidated balance sheet in accordance with the Fair Value Measurements and Disclosures Topic in the ASC. They are valued with assistance from a third-party trustee and consist of corporate bonds, government securities and fixed income mutual funds. The corporate bonds and government securities are valued using broker quotes that utilize observable market inputs, which are Level 2 inputs. The fixed income mutual funds are valued using unadjusted quoted prices for identical assets in active markets, which are Level 1 inputs.

Long-term Debt
Long-term debt, which includes finance leases, is reported at carrying amount on the consolidated balance sheets and is the Company's only financial instrument with fair values significantly different from their carrying amounts. The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.
The fair value of outstanding debt fluctuates with changes in a number of factors. Such factors include, but are not limited to, interest rates, market conditions, credit ratings, values of similar financial instruments, size of the transaction, cash flow projections and comparable trades. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules.

Carrying Value | 16,366 |  |  | 16,705 |

Interest Rate Derivatives
The Company’s forward starting interest rate swaps are carried at fair value and valued with assistance from a third party based upon pricing models using inputs observed from actively quoted markets. All of the inputs used to determine the fair value of the swaps are Level 2 inputs. The fair value of the Company’s forward starting interest rate swaps asset was $91 million and $80 million at December 31, 2021 and 2020, respectively. See Note 10, Debt and Credit Agreements, for further information.
Pension Plan Assets
Pension plan assets are reported at fair value, net of pension liabilities, on the consolidated balance sheet. The Investment Committee targets an allocation of pension assets to be generally 60% growth-oriented and 40% immunizing. See Note 9, Employee Benefit Plans, for further information. There are several valuation methodologies used for those assets as described below.
Investments in the Fair Value Hierarchy
•Common stock (Level 1): Valued at the closing price reported on the active market on which the individual securities are traded on the last day of the year and classified in Level 1 of the fair value hierarchy.
•Mutual funds (Level 1): Valued at the net asset value of shares held at year end based on quoted market prices determined in an active market. These assets are classified in Level 1 of the fair value hierarchy.
•Cash and cash equivalents (Level 1): Includes cash and short term investments with an original maturity of three months or less. The carrying value of cash and cash equivalents at year end approximates fair value. These assets are classified in Level 1 of the fair value hierarchy.
•Corporate bonds, government securities, asset-backed securities and derivatives (Level 2): Valued using price evaluations reflecting the bid and/or ask sides of the market for a similar investment at year end. Asset-backed securities include commercial mortgage-backed securities and collateralized mortgage obligations. These assets are classified in Level 2 of the fair value hierarchy.
Investments Measured at Net Asset Value
•Partnerships: Net asset value of private equity is based on the fair market values associated with the underlying investments at year end. These funds have redemption restrictions that require advanced notice of 15 business days.
•Commingled and common collective trust funds: This class consists of private funds that invest in corporate equity and debt securities, government securities and various short-term debt instruments and are measured at net asset value to estimate the fair value of the investments. The net asset value of the investments is determined by reference to the fair value of the underlying securities, which are valued primarily through the use of directly or indirectly observable inputs. These funds have redemption restrictions that require advanced notice of up to 30 business days.

NOTE 14. Other Income - Net
The Company derives income from items that are not considered operating activities. Income from these items is reported net of related expense. All components of net periodic pension and post-retirement benefit costs, excluding service cost, are included in other income - net on the consolidated income statement. Miscellaneous income (expense) may fluctuate due to timing and includes investment gains, losses and interest income as well as other non-operating activities.
For discussion of the drivers of changes in net periodic pension and post-retirement benefit credit from 2020 to 2021 and from 2019 to 2020, refer to Note 9, Employee Benefit Plans. Debt repurchase expense increased from 2019 to 2020 primarily as a result of long-term debt being redeemed earlier relative to maturity date. Other income – net consisted of the following:

Conrail
Through a limited liability company, CSX and Norfolk Southern Corporation (“NS”) jointly own Conrail. CSX has a 42% economic interest and 50% voting interest in the jointly-owned entity, and NS has the remainder of the economic and voting interests. Pursuant to the Investments-Equity Method and Joint Venture Topic in the ASC, CSX applies the equity method of accounting to its investment in Conrail.
Conrail owns rail infrastructure and operates for the joint benefit of CSX and NS. This is known as the shared asset area. Conrail charges fees for right-of-way usage, equipment rentals and transportation, switching and terminal service charges in the shared asset area. These expenses are included in purchased services and other on the consolidated income statements. Future payments due to Conrail under the shared asset area agreements are shown in the table below.

Also, included in equity earnings of affiliates are CSX’s 42 percent share of Conrail’s income and its amortization of the fair value write-up arising from the acquisition of Conrail and certain other adjustments. The amortization primarily represents the additional after-tax depreciation expense related to the write-up of Conrail’s fixed assets when the original purchase price, from the 1997 acquisition of Conrail, was allocated based on fair value. This write-up of fixed assets resulted in a difference between CSX's investment in Conrail and its share of Conrail's underlying net equity, which is $331 million as of December 2021.

NOTE 16. Other Comprehensive Income (Loss)
CSX reports comprehensive earnings or loss in accordance with the Comprehensive Income Topic in the ASC in the consolidated comprehensive income statement. Total comprehensive earnings are defined as all changes in shareholders' equity during a period, other than those resulting from investments by and distributions to shareholders (e.g., issuance of equity securities and dividends). Generally, for CSX, total comprehensive earnings equal net earnings plus or minus adjustments for pension and other post-retirement liabilities as well as other adjustments. Total comprehensive earnings represent the activity for a period net of tax and were $4.0 billion, $2.8 billion and $3.3 billion for 2021, 2020 and 2019, respectively.
While total comprehensive earnings is the activity in a period and is largely driven by net earnings in that period, accumulated other comprehensive income or loss (“AOCI”) represents the cumulative balance of other comprehensive income, net of tax, as of the balance sheet date. For CSX, AOCI is primarily the cumulative balance related to pension and other post-retirement benefit adjustments, interest rate derivatives and CSX's share of AOCI of equity method investees.

As a result of the acquisition of Quality Carriers, Inc. on July 1, 2021, CSX recognized goodwill and intangible assets. The goodwill of $213 million was calculated as the excess of the consideration paid over the fair value of net assets assumed as of July 1, 2021 and relates primarily to the ability of CSX to extend the reach of its network and gain access to new products, markets, and regions through a unique and competitive multimodal solution that leverages the reach of truck transportation with the cost advantage of rail-based services. Goodwill recognized in the acquisition is deductible for tax purposes. Prior to 2021, the Company's goodwill balance related to affiliates of CSXT, primarily P&L Transportation, Inc.
Intangible assets of $180 million consist of $150 million of customer relationships and $30 million of trade names that will be amortized over a weighted-average period of 20 years and 15 years, respectively.
In fourth quarter 2021, CSX performed its annual evaluation of each reporting unit's goodwill and intangible assets for impairment. No impairment was recorded as a result of this evaluation.

Based on that evaluation, management of CSX concluded that the Company’s internal control over financial reporting was effective as of December 31, 2021. Management's assessment of the effectiveness of internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute, assurance that the control system's objectives will be met.
The Company’s internal control over financial reporting as of December 31, 2021 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included elsewhere herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of CSX Corporation
Opinion on Internal Control Over Financial Reporting
We have audited CSX Corporation’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CSX Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of CSX Corporation as of December 31, 2021 and 2020, and the related consolidated statements of income, comprehensive income, cash flows, and changes in shareholders’ equity for each of the three years in the period ended December 31, 2021, and the related notes of the Company and our report dated February 16, 2022 expressed an unqualified opinion thereon.
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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, continued
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.
