Financial Information
See Item 7. Management’s DiscussionThe Compensation and Analysis of Financial Condition and Results of Operations for operating revenue, operating income and total assets for eachTalent Management Committee of the last three fiscal years.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, 2023, approximately 23% of CSX's overall workforce and 37% of management was diverse, calculated as the percentage of males of color and all females. In 2023, 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 fifth 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 190nearly 200 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, which now includes the network acquired from Pan Am, 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.Factors.

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 EPA is considering regulatory action directed towards the railroad industry governing the disposal of creosote cross-ties and seeking to increase air emission regulations that may impact our operations or increase costs. Similarly, 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.


CSX CORPORATION
PART I



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.

Positive Train Control
In 2008, Congress enacted Any new rules from the Rail Safety Improvement Act (the “RSIA”).  The legislation included a mandate that all Class I freight railroads implement an interoperable positive train control system (“PTC”) by December 31, 2015. Implementation of a PTC system is designed to prevent train-to-train collisions, over-speed derailments, incursions into established work-zone limits, and train diversions onto another set of tracks. On October 29, 2015, the President of the United States signed the Positive Train Control Enforcement and Implementation Act of 2015 into law extending the deadline. This Act requires the installation of all PTC hardware be completed by December 31, 2018, and, assuming certain conditions are met, requires that the PTC system be fully operational by December 31, 2020.

PTC must be installed on all main lines with passenger and commuter operations as well as most of those over which toxic-by-inhalation hazardous materials are transported. The Company expects to continue incurring significant capital costs in connection with the implementation of PTC as well as related ongoing operating expenses. CSX currently estimates that the total multi-year cost of PTC implementation will be approximately $2.4 billion for the Company. Total PTC investment through 2017 was $2 billion.
STB Proceedings
In 2012, the STB announced it would accept comments on a proposal by the National Industrial Transportation League that would require Class I railroads to provide a form of "competitive access" to customers served solely by one railroad. Under this proposal, CSX would be required to allow a competing railroad to access certain customers that are currently solely served by CSX's network. In early 2013, shippers, railroads and other parties submitted comments on the proposal, and the STB held a hearing in March 2014 to receive further input from participating parties. Since the hearing, the STB has taken no further action in the proceeding.

In April 2014, the STB announced it would receive comments to explore its methodology for determining railroad revenue adequacy. The revenue adequacy standard represents the level of profitability for a healthy carrier. Shippers, railroads and other parties filed comments in late 2014. The STB held a hearing in July 2015 to receive further input from participating parties. Since the hearing, the STB has taken no further action in the proceeding.

CSX participated in a public listening session on October 11, 2017 at the STB in response to service complaints. During the session, the Company addressed customer concerns and detailed the Company’s service recovery plans at that time.  At the STB's request, CSX is providing additional operating measures on a weekly basis that are available on the Company's website.

New rules 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.

Item 1A.  Risk Factors


The risks set forth in the following risk factors could have a materiallymaterial adverse effect on the Company's financial condition, results of operations or liquidity, and could cause those results to differ materially from those expressed or implied in the Company's forward-looking statements. Additional risks and uncertainties not currently known to the Company or that the Company currently does not deem to be material also may materially impact the Company's financial condition, results of operations or liquidity.

Regulatory, Legislative and Legal

New legislation, or regulatory changes or other governmental actions could impact the Company's earnings or restrict its ability to independently negotiate prices.
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. For instance, several of the proposals under consideration by the STB could have a significant negative impact on the Company's ability to negotiate prices for the value of rail services provided and meet service standards, which could force a reduction in capital spending. In addition, statutes imposingor regulations that, among other things, impose 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, local and federal regulatory agencies for a variety of economic, health, safety, labor, environmental, tax, legal, cybersecurity 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 impactaffect service performance. For example, the RSIA mandates that the installation of PTC hardware be completed by December 31, 2018 and, assuming certain conditions are met, requires that the PTC system be fully operational by December 31, 2020 on main lines that carry certain hazardous materials and on lines that have commuter or passenger operations. Although CSX remains on track to meet this regulatory requirement, noncomplianceNoncompliance with these and other 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.

The Company’s business strategies may not achieve the anticipated objectives.
The implementation of the Company’s business strategies could result in operational disruptions, loss of existing customers, regulatory issues and other adverse consequences. If these strategies fail to achieve the anticipated benefits or take longer to implement than expected, the Company’s operations and financial results may be adversely affected.

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. Approximately 70 percent of these agreements are bargained for nationally by the National Carriers Conference Committee and 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 of the U.S. President), during negotiations neither party may take action until the procedures are exhausted. If, however, CSX is unable to negotiate acceptable agreements, or if terms of existing agreements are disputed, 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. Additionally, from time to time, the Company enters into CSX-specific, or “local”, bargaining agreements which could also be critical to the Company and its new business strategies.

CSX CORPORATION
PART I



Network constraints could have a negative impact on service and operating efficiency.
CSXT could experience rail network difficulties related to: (i) increased volume; (ii) locomotive or crew shortages; (iii) extreme weather conditions; (iv) impacts from changes in yard capacity, or network structure or composition, including train routes; (v) increased passenger activities, including high-speed rail; or (vi) regulatory changes impacting where and how fast CSXT can transport freight or maintain routes, which could have a negative effect on CSXT's operational fluidity, leading to deterioration of service, asset utilization and overall efficiency.

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, if the rate of economic growth in Asia slows, European economies contract, or if the global supply of seaborne coal or price of seaborne coal changes from its current levels, U.S. export coal volume could be adversely impacted resulting in lower 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.
Changing dynamics in the U.S. and global energy markets could negatively impact profitability.
Over the past few years, production and source locations of natural gas in the U.S. have also increased dramatically, which has resulted in lower natural gas prices in CSX’s service territory. As a result of sustained low natural gas prices, many coal-fired power plants have been displaced by natural gas-fired power generation facilities. If natural gas prices were to remain low, additional coal-fired plants could be displaced, which would likely further reduce the Company's domestic coal volumes and revenues. Additionally, crude oil prices combined with increased pipeline activity have resulted in volatility in domestic crude oil production, which has adversely affected crude oil volumes for CSX.


CSXT, as a common carrier by rail, is required by law to transport hazardous materials whichand could expose the Company to significant costsbe adversely impacted by non-compliance with applicable regulations or from regulatory 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.

legislative changes.
CSXT is also required to comply with regulations regarding the handling of hazardous materials. In November 2008,materials and has a legal obligation to transport certain hazardous materials under the common carrier mandate. Applicable rules issued by the TSA issued final rules placingplace 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.

The Company may be subject to various claims and lawsuits that could result in significant expenditures.
Climate changeAs part of its railroad and other emissions-related lawsoperations, the Company is subject to various claims and regulationslawsuits related to disputes over commercial practices, labor and unemployment matters, occupational and personal injury claims, property damage or freight 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 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. During a health crisis, policies and initiatives may be instituted by the public and private sector to reduce transmission, 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. These policies or initiatives could adversely affect demand for the commodities and products that the Company transports, including import and export volume.

In addition, initiatives to reduce transmission could result in supply chain disruptions, which could impact volumes and make it more difficult for the Company to serve its customers. 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 a public health crisis 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’ information 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 or its key third-party vendors' 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.

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, software bugs, server malfunctions, software or hardware failures, human error, fraud, or other modes of attack or disruption. Attacks of these nature are increasing in frequency, levels of persistence, intensity and sophistication, including by nation-state threat actors or those associated with nation-states. Further, the Company may be at increased risk of experiencing a cyber-attack as a result of being a component of the critical U.S. infrastructure. If such an event takes place, the Company may be required to incur significant expenses in excess of existing cybersecurity insurance coverage. 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 Company or its third-party vendors may also 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. Due to applicable laws, rules 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.

Additionally, if CSX is unable to successfully acquire, develop or implement new technology, including artificial intelligence, it may suffer a competitive disadvantage within the rail industry and with companies providing other modes of transportation services.

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) locomotive or crew shortages; (ii) labor shortages or other service disruptions in the supply chain affecting trucking, ports, handling facilities, customer facilities or other railroads; (iii) unpredictable increases in demand; (iv) extreme weather conditions; (v) regulatory changes resulting in forced access or impacting where and how fast CSXT can transport freight or maintain routes; (vi) reductions in availability of pooled equipment, including chassis; (vii) impacts from changes in network capacity or structure; or (viii) increased passenger activities, which could impact CSXT's operational fluidity, leading to deterioration of service, asset utilization and overall efficiency.

CSXT, as a common carrier by rail, transports hazardous materials, which could expose the Company to significant costs and claims in the event of a train accident.
A train accident involving the transport of hazardous materials could result in significant costs and 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, which could have a material adverse effect on the Company's results of operations, financial condition, and liquidity. Under federal regulations, CSXT is required to transport certain hazardous materials under the legal duty referred to as the common carrier mandate regardless of risk or potential exposure to loss.

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.

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, hurricanes, fires 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. Hurricanes as well as storm and flooding events have impacted the Company's network in the past, leading to interrupted service and damage to track and equipment. Changes in weather patterns caused by climate change are expected to increase the frequency, severity or duration of certain adverse 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, embargoes or 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 or continues to experience the impacts of inflation, 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.

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, including the impacts of regulation and alternative fuel sources, 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 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, significant increases in interest rates, 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, including engineers and conductors as well as other skilled professional or technical employees, 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, freight cars 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. 

Climate Change and Environmental

The Company’s operations and financial results.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.emissions as well as requirements to disclose information relating to climate change. 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, 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. In addition, CSX may become subject to legal requirements to disclose climate change related information and may become subject to demands or expectations by its supply chain partners, customers or other stakeholders to disclose information relating to climate risk or set related targets or goals. The Company's current practices with respect to climate risk disclosure may fail to meet these developing legal requirements or stakeholder demands or expectations. In addition, legislative or regulatory uncertainties and change regarding climate-related risks, including inconsistent perspectives or requirements, are likely to result in higher regulatory, compliance, credit, reputational and other risks and costs.

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 clean-upcleanup 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.
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 performance and reliability of the Company's technology systems are critical to its ability to operate and compete safely and effectively. A cybersecurity attack, which is a deliberate theft of data or impairment of information technology systems, or other significant disruption or failure, could result in a service interruption, train accident, misappropriation of confidential information, process failure, security breach or other operational difficulties. Such an event could result in decreased revenues and increased capital, insurance or operating costs, including increased security costs to protect the Company's infrastructure. Insurance maintained by the Company to protect against loss of business and other related consequences resulting from cyber incidents may not be sufficient to cover all damages. A disruption or compromise of the Company's information technology systems, even for short periods of time, could have a material adverse effect.

Item 1C.  Cybersecurity

Cybersecurity Risk Management and Strategy
Strong performance and reliability of the Company's technology systems are critical to operating safely and effectively, and protecting personal and customer data is essential to maintaining stakeholder trust. The Company has implemented processes designed to assess, identify, and manage material cybersecurity risks, as described further below. CSX maintains a cybersecurity framework that is integrated across the organization through people, processes and technology to help protect the personal information of its customers, its contractors and its suppliers as well as protect the integrity of its own operations. Cybersecurity is also integrated into the Company’s Enterprise Risk Management (“ERM”) program. The Company equips CSX systems with various cybersecurity tools, conducts vulnerability scans and provides critical cybersecurity information to application users, as appropriate. The Company also takes proactive measures to advise CSX employees of how they can assist the Company in its cybersecurity practices. CSX informs employees on cybersecurity best practices, including how to identify cyber-related suspicious activity, how to report such activity and, as appropriate, proactive measures employees can take to safeguard company information and devices. The Company also provides cybersecurity awareness training to employees and conducts cybersecurity testing exercises to help maintain cybersecurity vigilance. With the assistance of third-party consultants, the Company conducts an annual cybersecurity exercise, which is often a "tabletop" scenario involving a cross-functional group responding to a hypothetical cybersecurity threat.

The Company considers its material cybersecurity-related risks, as described in more detail below and at Item 1A. Risk Factors, and applies various frameworks to establish controls that are reasonably designed to identify, protect, detect, respond to, and recover from significant cybersecurity incidents. The Company also tests its cybersecurity program to assess whether enhancements to cybersecurity measures are appropriate, such as additional detection and prevention capabilities. These tests may include the use of internal or third-party external risk assessments, and penetration testing. The Company also conducts periodic cybersecurity assessments, as appropriate, pursuant to its annual risk assessment process. Third party resources may also be used for these assessments.

As part of its cybersecurity program, CSX partners with a third-party to provide a managed service that is designed to enable continuous monitoring at its Security Operation Center ("SOC"). The SOC has established processes to identify, address, and remediate cybersecurity threats or vulnerabilities. This includes the engagement, where necessary, of third-party experts, advisors, and other cybersecurity professionals that have been retained by the Company to assist in responding to cybersecurity incidents or threats. Company processes also include various procedures for notifying members of the company's cybersecurity department, Chief Information Security Officer ("CISO"), legal department, accounting department, and others as applicable.

The Company has processes designed to provide reasonable oversight for the identification of cybersecurity risks associated with certain third-party service providers. As appropriate, the Company requires certain third-party providers to complete a cybersecurity questionnaire, to provide Service Organization Control assessment results, if such results exist, or to agree to contractual language regarding cybersecurity and incident notification obligations in agreements with the company. CSX also has processes that help monitor risks associated with its key third-party vendors’ technology systems, including, where appropriate, performing security assessments of cyber incidents through dashboard alerting for reported events. CSX’s internal cybersecurity processes and disclosure protocols consider cybersecurity incidents involving key applications provided by third-parties.

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 as discussed in more detail in Item 1A. Risk Factors. In light of the numerous cybersecurity risks that CSX faces, it is reasonably likely that any of the related risks, individually or collectively, if significant, could materially affect the Company’s operations, including but not limited to service interruption, train accident or derailment, misappropriation of confidential or proprietary information (including personal information), process failure, or other operational difficulties.

Cybersecurity Governance
The cybersecurity program and related risks at CSX are managed by the VP Technology and CISO. The Company's CISO is a Certified Information Systems Auditor with over 30 years of industry experience including information security leadership positions at multiple publicly-traded companies.

The CISO is notified of cybersecurity events as needed based on the Company’s processes for addressing cybersecurity incidents and threats. The CISO is supported by a team that includes the SOC, which consists of the Deputy Chief Information Security Officer and other cybersecurity professionals as well as a team of third-party contractors. The SOC, with the assistance of outside third-parties as needed, analyzes, evaluates and remediates cybersecurity incidents and provides investigative information to the CISO. Depending on the significance of any specific cybersecurity incident or threat, and/or relation to prior incidents, the CISO will escalate relevant information, as appropriate, and the Company’s legal and accounting groups, with assistance from other company departments and third parties, will assist in assessing potential SEC disclosure obligations. The CISO coordinates disclosure to other agencies, when necessary, including requirements under the Transportation Security Administration directives.

More significant cybersecurity incidents or threats may result in notifications to senior leadership and, if necessary, to the Audit Committee and the Board of Directors. Additionally, a cybersecurity governance briefing takes place quarterly with leaders from the Company's technology, operations, commercial, legal, and accounting departments to discuss cybersecurity risks, threats, and incidents, including updates from the SOC and an assessment of ways to mitigate and remediate any threats or incidents the Company may be facing.

The Company's Audit Committee of the Board of Directors oversees the Company's cybersecurity risk, mitigation strategies and overall resiliency of the Company’s technology infrastructure. Such risk is managed as part of the Company’s overall risk management and business continuity processes and is included in the ERM program, which is also overseen by the Audit Committee. The Audit Committee periodically reviews assessments of information security controls and procedures, any incidents that could have a potentially significant impact on the company’s network, as well as potential cybersecurity risk disclosures. The Company's senior leadership team briefs the Audit Committee and Board of Directors at least annually on information technology and cybersecurity matters, including more frequent updates as circumstances warrant. Such annual updates include significant findings or updates by internal or external evaluations. The Audit Committee is apprised annually on emerging risks to the Company, including education on cybersecurity-related matters as needed. CSX has a cybersecurity expert on the Board and its Audit Committee to provide expanded oversight of the Company’s cybersecurity and technology systems.

Network Geography
CSXT’s operations are primarily focused on four major transportation networks and corridors whichthat 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 rail markets – merchandise, coalintermodal and intermodal.coal.

RESULTS OF OPERATIONS
Tax Reform
With the enactment of the Tax Cuts and Jobs Act (the "Act") on December 22, 2017, the federal corporate income tax rate was reduced from 35% to 21% effective January 1, 2018. The Company's 2017 financial results included a $3.5 billion, or $3.81 per share, non-cash reduction in income tax expense, primarily resulting from revaluingfollowing section generally discusses the Company's net deferred tax liabilities to reflectresults of operations and financial condition for the recently enacted lower tax rate effective January 1, 2018. Beginning in 2018, CSX expects its effective federal and state income tax rate to be approximately 25%.

The Company's affiliates also revalued their deferred tax liabilities to reflect the lower federal corporate tax rate, which resulted in the Company recognizing a benefit of $142 million, or $0.10 per share after-tax, in equity earnings of affiliates, which is included in operating income. (See additional discussion over income taxes in Note 11, Income Taxes and equity earnings of affiliates in Note 12, Related Parties and Affiliates.)

Interest Expense
Interest Expense includes interest on long-term debt and related fair value hedges, equipment obligations and capitalfinance leases. Interest expense decreased $33 million to $546 million due to lower average interest rates and $11 million of additional expense in 2016 related to the extra week, partially offset by higher average debt balances.

Income Tax Benefit (Expense) decreased $3.4 billion from an expense of $1.0 billion in 2016 to a benefit of $2.3 billion in 2017 primarily due to a $3.5 billion non-cash reduction in income tax mostly resulting from the revaluation of the Company's net deferred tax liabilities to reflect the recently enacted 21 percent federal corporate tax rate. This reduction was partially offset by additional income tax expense resulting from increased earnings before income taxes.

Net Earnings increased $3.8 billion to $5.5 billion, and earnings per diluted share increased $4.18 to $5.99, due to the factors mentioned above, including the significant impact of tax reform. Lower average shares outstanding resulting from higher share repurchase activity had a positive impact on earnings per diluted share.

Revenue
In 2016, revenue decreased $742 million, or six percent, due to a five percent decline in volume (including the $178 million positive impact of an extra week of volume) and a significant decline in fuel recoveries, partially offset by increased pricing.

Merchandise
Chemicals - Volume declined as energy market headwinds significantly reduced crude oil and frac sand shipments. This reduction was partially offset by the ramp up of a fly ash remediation project and a modest increase in core chemical markets.

Automotive - Volume increased as a result of strong North American light vehicle production and growth across several customers. Additionally, movement of trucks and SUVs continued to outpace passenger cars, consistent with customer buying patterns.

Agricultural and Food Products - Volume declined as the strong U.S. dollar continued to support import grain and a robust Southeastern crop spurred additional local truck sourcing, displacing grain shipments by rail. Additionally, ethanol market dynamics shifted to favor the Gulf region for storage and export, precluding CSX from participation in shipments from Western origins to the Gulf.

Minerals - Volume was up slightly due to strong gains in aggregates (which include crushed stone, sand and gravel), particularly for highway and non-residential construction in southern markets. The growth was partially offset by headwinds in salt and lime, reflecting mild winter weather and steel production challenges, respectively.

Fertilizers - Volume was flat as the strong U.S. dollar, which drove high levels of imported sulfur, displaced rail transport, and nitrogen demand fell in anticipation of further commodity price deterioration. This offset growth in phosphate rock, driven by operational efficiency that allowed for additional rail traffic conversion that would otherwise move by truck.

Forest Products - Volume declined as headwinds from electronic substitution and reduced paper products demand drove industry consolidation that reduced rail volume. Further, excess truck capacity in 2016 captured some volume that traditionally moved by rail.

Metals and Equipment - Volume was down as the strong U.S. dollar allowed for continued high levels of steel imports, which led to reduced domestic steel production, mill closures and the loss of associated rail moves. These declines were partially offset by strength in the wind-energy and power generation markets.

Coal
Domestic - Volume declined 23 percent as mild winter weather in the beginning of the year and low natural gas prices reduced utility coal burn rates and resulted in inflated coal stockpiles. Further, the weak domestic integrated steel market drove volume decreases in coke.

Export - Volume was down 15 percent in both metallurgical and thermal coal as a result of the strong U.S. dollar and global oversupply which impacted U.S. competitiveness in the world market, particularly in the first half of the year.


CSX CORPORATION
PART II


Intermodal
Domestic - Volume increased 4 percent as secular growth and new service offerings were partially offset by excess truck capacity headwinds and a short-haul competitive loss.

International - Volume declined 9 percent as headwinds from competitive losses more than offset moderate growth across other customers.

Other
Other revenue decreased $110 million versus prior year primarily due to payments received in 2015 from customers that did not meet volume commitments. Further decreases in incidental revenue as well as lower coal revenue from affiliates were partially offset by adjustments to revenue reserves.

Expense
In 2016, total expenses decreased $547 million, or seven percent, compared to prior year. Descriptions of each expense category as well as significant year-over-year changes are described below. Year-over-year changes related to the extra week are estimated incremental expenses of $116 million incurred for the week of December 24 through December 30, 2016.
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 $131 million due to the following items:
Efficiency savings of $249 million were driven by lower T&E and operating support costs as a result of structural changes, reduced crew training and the Company's train length initiative that began in the second quarter of 2015.
Volume-related costs were $116 million lower.
Incentive compensation was $111 million higher reflecting the expected award payouts on existing plans.
Inflation resulted in $106 million of additional cost driven by increased health and welfare costs.
The extra week resulted in $51 million of additional cost.
Restructuring costs decreased $37 million due to the 2015 workforce reduction initiatives costs that nearly all occurred in 2015.
Various other costs increased $3 million.

Materials, Supplies and Otherexpenses consist primarily of contracted services to maintain infrastructure and equipment, terminal and coal 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 materials, supplies and other expenses decreased $264 million driven by the following:
Real estate gains increased $98 million primarily related to a current year gain of $115 million related to the sale of an operating property and other related income partially offset by a prior year real estate gain.
Efficiency savings of $95 million were primarily related to lower operating support costs driven by structural changes and broad cost containment.
Train accident and casualty costs were $70 million lower due to the continuing declines in the severity of train accidents as well as injuries.
Inflation resulted in $34 million of additional costs.
The extra week resulted in $18 million of additional cost.
Volume-related costs were $11 million lower.
Various other costs decreased $42 million.

Depreciation expense primarily relates to recognizing the costs of a capital asset, such as locomotives, railcars and track structure, over its useful life. This expense is impacted primarily by the capital expenditures made each year. Depreciation expense increased $93 million due to a larger asset base and the $25 million impact of the extra week in 2016.

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 $244 million driven by the following:
Average fuel price per gallon decreased 18 percent, from $1.80 to $1.48 per gallon versus the prior year, which reduced expenses by $137 million.
Efficiency savings of $60 million were primarily related to locomotive fuel reduction technology and process improvement.
Volume-related costs were $58 million lower.
The extra week resulted in $15 million of additional cost.
Various other costs decreased $4 million.

Equipment and Other expenses include 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 lease expenses for locomotives, railcars, containers and trailers, offices and other rentals. These expenses increased $9 million driven by the following:
Inflation resulted in $18 million of additional cost primarily related to rates on automotive freight cars.
Volume related costs were $14 million higher due primarily to growth in automotive volume.
The extra week resulted in $7 million of additional cost.
Efficiency savings of $23 million were due to improved car cycle times.
Net other costs decreased $7 million.

Equity Earnings of Affiliates increased $10$67 million primarily as a result of higher rental volumes and decreased costs at TTX.

Interest Expense increased $35 million to $579 million due to higher average debt balances in addition to $11 million of additional expense related to the extra week in 2016, partially offset by lower averageand higher effective interest rates.


Debt Repurchase Expense increased to $115 million due to the repurchase of certain notes that were expected to mature in 2017, 2018 and 2019.

Other Income (Expense) - Net
Other Income - Net includes investment gains, losses, interest income, components of net decreased $52 million to $46 periodic pension and post-retirement benefit cost and other non-operating activities. Other income increased $6 million primarily due to a prior year $59 million gain on a sale of non-operating easementshigher interest income and reimbursement of environmental costs of $21 million related to this sale. This decrease wasother non-significant items, partially offset by other non-operating items, none of which were individually significant.a decrease in net pension benefit credits.


Income Tax Expense
Income Tax Expense decreased $143$72 million to $1.0 billion primarily due to lower earnings.earnings before income taxes, partially offset by prior year favorable state legislative changes.


Net Earnings and Earnings per Diluted Share
Net Earnings decreased $254$451 million to $1.7$3.7 billion, and earnings per diluted share decreased $0.19$0.10 to $1.81$1.85, due to the factors mentioned above. Lower averageAverage shares outstanding resulting from higherwas lower as a result of share repurchase activity during the year and had a positivefavorable impact on earnings per diluted share.

Non-GAAP Measures - UnauditedNON-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.


Adjusted Operating ResultsEconomic Profit
Management believes Economic Profit (CSX Cash Earnings or CCE) provides additional perspective to investors about financial returns generated by the business by representing a profit generated over and above the cost of capital used by the business to generate that adjustedprofit. Economic Profit is designed to incentivize strategic investments that earn more than the required return. Increases in Economic Profit indicate that the Company is effectively allocating capital and rewarding shareholders by generating growth in excess of the incremental cost of capital associated with reinvestment in the business. This measure should be considered in addition to, rather than a substitute for, net income. This measure is defined by the Company as gross cash earnings minus the capital charge on gross operating assets. Gross cash earnings is calculated as Adjusted Earnings before Interest, Taxes, Depreciation and Amortization ("Adjusted EBITDA"), less an assumed 15% cash tax. The capital charge uses a long-term average cost of capital of 8% multiplied by the gross operating assets. CSX's gross operating assets include gross properties and other non-cash assets, net of non-interest bearing liabilities.
The following table reconciles net income (GAAP measure) to Economic Profit (non-GAAP measure).

Adjusted Free Cash Flow
Free cash flow is considered a non-GAAP financial measure under SEC Regulation Gand Regulation S-K Item 10(e). 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 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 is calculated by using net cash from operations and adjusting for property additions and certain other investing activities. Free cash flow before dividends increased $854decreased $412 million year-over-year to $1.7 billion. The increase in free cash flow from the prior year is$3.3 billion primarily due to lower proceeds and advances from property dispositions, mostly attributable to the sale of property rights to the Commonwealth of Virginia in the prior year, as well as higher property additions of $358 million, voluntary contributions to the Company's qualified pension plans of $250 million in 2016 and higherless cash from operating activities. Cash from operating activities includes lower cash-generating net earnings from operations. Adjusted free cash flow excludesand the impact cashof $168 million of higher payments for retroactive wages and bonuses, and associated taxes, related to finalized labor agreements as well as the offsetting impact of $135$381 million of postponed federal estimated tax payments, which were extended until first quarter 2024 under an Internal Revenue Service tax relief announcement for restructuring charge.those impacted by Hurricane Idalia.

The Company measures and reportsis committed to continuous improvement in safety and service performance. The Company strives for continuous improvement in these measuresperformance through training, innovation and investment. Investment in trainingTraining and technology also is designed to allow CSX employees to have an additional layer of protection that can detect and avoid many types of human factor incidents. The Company's 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.


CSX’s FRA reportable personal injury frequency index of 1.19 for the full year of 2017 was 13 percent unfavorable versus the prior year as man-hours fell by nine percent while overall injuries were up slightly. While the FRA train accident frequency rate increased year-over-year, overall FRA train accidents remained flat and train miles decreased 12 percent year-over-year. CSX remains committed to ongoing safety improvement, with a focus on reducing injury severity and avoiding catastrophic events.

In order to more accurately represent the Company’s operating performance, CSX revised the way it calculates train velocity and terminal dwell effective third quarter 2017. These revisions are consistent with the principles of scheduled railroading. Updated definitions for each key performance measure are included beneath the Operating Statistics table. Prior periods have been restated to conform to the current methodology. Details of the changes are as follows:
Train velocity has been expanded to include intermediate dwell, now measuring end-to-end transit time.
Dwell has been expanded to include car dwell time at terminals on through trains, now measuring all car dwell time on an end-to-end trip.

CSX CORPORATION
PART II


These revisions differ from the methodology prescribed by the Surface Transportation Board ("STB") for reporting train velocity and dwell. CSX will continue to report train velocity and dwell to the STB on a weekly basis using the prescribed methodology. At the STB's request, CSX is providing additional operating measures on a weekly basis that are available on the Company's website.

CSX’s operating performance improved versus the prior year in certain categories as network fluidity challenges in the third quarter of 2017 were offset by substantial improvement from the implementation of scheduled railroading and a balanced train plan. Going forward, CSXThe Company remains focused on executingsafety, service, and controlling costs. Velocity and dwell improved 12% and 17%, respectively, relative to 2022. Carload trip plan performance improved to 84% compared to 64% while intermodal trip plan performance improved to 95% compared to 90%, relative to 2022. CSX has seen an improvement in service metrics throughout 2023.

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 balance sheet, sources and uses of cash, flowbalance sheet and external factors should be reviewed.

Material Changes in the Consolidated Balance Sheets and Significant Cash Flows
Consolidated Balance Sheets
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.

Total assets as well as total liabilities and shareholders' equity increased $325 million from prior year. The increase in assets was driven by higher net properties of $614 million resulting from capital investment and an increase in affiliates and other companies of $160 million primarily resulting from the benefits of recent tax reform. These increases were partially offset by a decrease in cash and short-term investments of $601 million. The increase in total liabilities and shareholders' equity combined was driven by net earnings of $5.5 billion, partially offset by the decrease in deferred income taxes of $3.2 billion as a result of recent tax reform and share repurchases of $2.0 billion.


Significant Cash Flows
The following charts present nethighlight the operating, investing and financing components of the change in cash provided by (used in)and cash equivalents for operating, investing and financing activities for full years 2017, 20162023 and 2015.2022.

663664665
In 2023, the Company generated $5.5 billion of cash from operating activities, which was $70 million less than prior year primarily driven by lower cash-generating net earnings and $168 million higher payments for retroactive wages and bonuses, including the associated taxes, related to finalized labor agreements. This decrease was partially offset by the impact of $381 million of postponed federal estimated tax payments mentioned above. Net cash used in investing activities was $2.3 billion, an increase in net spend of $156 million from the prior year primarily due to lower proceeds from property dispositions and higher property additions, partially offset by decreased acquisition spending. Cash used in financing activities was $3.9 billion, which represents an increase in net spend of $98 million from the prior year primarily due to lower proceeds from the issuance of long-term debt, partially offset by lower share repurchases.

Sources of Cash and Liquidity
The Company has multiple sources of cash. First, theliquidity, including cash generated from operations and financing sources. The Company generates cash from operations. In 2017, the Company generated $3.5 billion of cash provided by operating activities which was $431 million higher than prior year primarily driven by $250 million in voluntary contributions in 2016 to the Company's qualified pension plans and higher net earnings, partially offset by payments related to restructuring activities. In 2016, the Company generated $3.0 billion of cash provided by operating activities which was $329 million lower than 2015 primarily driven by $250 million in voluntary contributions to the Company's qualified pension plans.
Second, CSX has access to numerous financing sources including a $1 billion five-year unsecured revolving credit facility that expires in May 2020.  As of the date of this filing, the Company has no outstanding balances under this facility. See Note 9, Debt and Credit Agreements for more information.

Third, CSX filed a new shelf registration statement with the SEC inon February 201616, 2022, which is unlimited as to amount and 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 2023, CSX issued $600 million of long-term debt. See Note 10, Debt and Credit Agreements for more information.


CSX has access to a $1.2 billion five-year unsecured revolving credit facility backed by a diverse syndicate of banks that expires in February 2028. As of December 31, 2023, the Company had no outstanding balances under this facility. 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, 2023, 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 2023, CSX continued to invest in its business to create long-term value for shareholders. In 2017, net cash used in investing activities was $1.5 billion, a decrease of $303 million from the prior year primarily driven by lower property additions. In 2016, net cash used in investing activities was $1.8 billion, a decrease of $1.1 billion from 2015 primarily driven by lower net purchases of short-term investments and lower property additions.

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.

Planned capital investments for 20182024 are expected to be $1.6 billion, including about $200 million for PTC. Of the 2018 investment, the majorityapproximately $2.5 billion. Spending to sustain core infrastructure with a focus on safety and reliability will be useda top priority. In addition, management is committed to sustain the core infrastructure. The remaining amounts will be allocated toinvestments that promote profitable growth, including projects supporting productivity initiatives, service enhancements and profitable growth.productivity initiatives, including investments in locomotives and freight cars. CSX intends to fund capital investments primarily through cash generated from operations.


The Company expects to continue incurring significant capital costs in connection with the implementation of PTC. CSX estimates that the total multi-year cost of PTC implementation will be approximately $2.4 billion. This estimate includes costs for installing the new system along tracks, upgrading locomotives, adding communication equipment and developing new technologies. Total PTC spending through 2017 was $2.0 billion.

In addition to capital investments, the Company uses cash for scheduled payments of debt and leases, share repurchases and to pay dividends to shareholders. In April 2017, the Company announced an 11 percent increase in the quarterly cash dividend to $0.20 per common share. In 2017, net cash used in financing activities was $2.2 billion, which represents an increase in spending of $911 million from the prior year primarily driven by higher share repurchases and lower net debt issued, partially offset by the repayment of seller-financed assets in the prior year. In 2016, net cash used in financing activities was $1.3 billion, which represents an increase in spending of $749 million from 2015 primarily driven by the repayment of seller-financed assets, higher share repurchases, and lower net debt issued.

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 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 14, 2024, the Company's Board of Directors authorized a 9% increase in the quarterly cash dividend to $0.12 per common share effective March 2024. 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
Currently,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 $419 million$1.4 billion of cash, cash equivalents and short-term investments. CSX has

The Company has a receivables securitization facility with a three-year term scheduled to expire in September 2019. The purpose of this facility is to provide an alternative to commercial paper and a low cost source of short-term liquidity of up to $200 million, depending on eligible receivables balances. Under the terms of this facility, CSXT transfers eligible third-party receivables to CSX Trade Receivables, a bankruptcy-remote special purpose subsidiary. A separate subsidiary of CSX services the receivables. Upon transfer, the receivables become assets of CSX Trade Receivables and are not available to the creditors of CSX or any of its other subsidiaries. In the event CSX Trade Receivables draws under this facility, the Company will record an equivalent amount of debt on its consolidated financial statements.

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 stableimproved during 2017.

The Company is committed to maintaining an investment grade credit rating. If CSX's credit ratings were to decline to below investment gradeinvestment-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.

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 and legal reserves;
pension and post-retirement medical plan accounting; and
depreciation policies for assets under the group-life method; andmethod
income taxes.


Personal Injury and Environmental and Legal Reserves

Personal Injury
Personal Injury reserves of $168$128 million and $170$126 million for 20172023 and 2016,2022, 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. As a direct result of improvements in safety in recent years, the Company has experienced a downward trend in the severity of injuries which has resulted in a decrease in the estimate of costs per incident. 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 $90$154 million and $95$161 million in 2017for 2023and 2016,2022, 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 214230 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.

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. The Company evaluates all exposures relating to legal liabilities at least quarterly and adjusts reserves when appropriate. The amount of a particular reserve may be influenced by factors that include official rulings, newly discovered or developed evidence, or changes in laws, regulations and evidentiary standards. An unexpected adverse resolution of one or more of these items could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period. For additional details, including a description of our related accounting policies, see Note 5, Casualty, Environmental and Other Reservesin the consolidated financial statements. Additionally, see Item 3. Legal Proceedings for further discussion of these items.


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 inbetween 2003 or thereafter,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 2017,2023, the projected benefit obligation for the Company’s pension plans was $3.0$2.3 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. Eligible retirees who are age 65 years or older (Medicare-eligible) are covered by a health reimbursement arrangement, which is an employer-funded account that can be used for reimbursement of eligible medical expenses. Eligible retirees younger than 65 years (non-Medicare eligible) are covered by a self-insured program partially funded by participating retirees. The life insurance plan is non-contributory. As of December 2017, the projected benefit obligation for the Company’s other post-retirement benefit plans was $250 million.

For information related to the funded status of the Company's pension and other post-retirement benefit plans, see Note 8, 9, Employee Benefit Plans.


The accounting for these plans is subject to the guidance provided in the Compensation-Retirement Benefits Topic in the ASC.Accounting Standards Codification ("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; and
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.

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.


Beginning in 2017, theThe 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 instead of a single weighted-average discount rate approach, which was used in prior years. The Company made this change to improve the correlation between projected pension and post-retirement benefit liability cash flows and the corresponding spot discount rates and to provide a more precise measurement of service and interest costs.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 calculated pension and post-retirement benefits liabilities are consistent under both the traditional and spot rate approaches. The Company accounted for this change on a prospective basis as a change in accounting estimate.


The weighted average discount rates used by the Company to value its 2017 pension and post-retirement obligations are 3.56 percent and 3.34 percent, respectively. For 2016, the weighted average discount ratesrate used by the Company to value its pension obligations was 4.82% and post-retirement obligations were 4.08 percent5.02% as of December 2023, and 3.71 percent,December 2022, 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 2017,2023, the estimated duration of pensions and post-retirementpension benefits is approximately 12 years and seven years, respectively.9 years.


Each year, thesethe discount rates arerate is 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 ratesrate 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 and economists 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,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 percent6.75% in both 20172023 and 2016.2022.

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 percent in both 2017 and 2016 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, retirement age and retirement age.salary inflation rates. These assumptions are based upon historical data, recent plan experience and industry trends and are determined by management.

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%84% of total fixed assets of $44$50.3 billion on a gross basis at December 2017.31, 2023. The remaining depreciable assets of the Company, including non-railroad assets and assets under capitalfinance leases, are depreciated using the straight-line method on a per asset basis. Land is not depreciated.

Critical Accounting Estimates, continued


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 assumptions regardingmethods 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.


Recent experience withThe STB requires depreciation studies hasbe 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 2022, both of which resulted in changes to accumulated depreciation, rate changes that did not materially affect the Company’sservice lives, salvage values, and other related factors for certain assets. The 2022 equipment study resulted in an increase in annual depreciation expense of $1.3 billion, $1.3 billion and $1.2 billion for 2017, 2016 and 2015 respectively.approximately $80 million primarily due to deferred losses on assets depreciated using the group-life method. A one percentdepreciation study was not performed in 2023.

A 1% change in the average estimated useful life of all group-life assets would result in an approximate $12$13 million change to the Company’s annual depreciation expense. There were no significant changes to the Company's asset lives as a result of the 2022 and 2020 studies. For additional details, including a more detailed description of our related accounting policies, see Note 6, Properties, in the consolidated financial statements.

Income Taxes
CSX accounts for income taxes in accordance with the Income Taxes Topic in the ASC that addresses how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this topic, the Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The amount recognized in the financial statements from such a position is measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution.

CSX files a consolidated federal income tax return, which includes its principal domestic subsidiaries. Examinations of the federal income tax returns of CSX have been completed through 2015. During 2017, the Company participated in a contemporaneous Internal Revenue Service (“IRS”) audit of tax years 2016 and 2017. Management believes an adequate provision has been made for any adjustments that might be assessed. While the final outcome of these matters cannot be predicted with certainty, it is the opinion of CSX management that none of these items will have a material adverse effect on the financial condition, results of operations or liquidity of CSX. An unexpected adverse resolution of one or more of these items, however, could have a material adverse effect on the results of operations in a particular fiscal quarter or fiscal year. As of December 2017, the Company’s uncertain tax positions were $24 million.

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 does not hold or issue derivativemay use certain financial instruments for trading purposes. Historically,such as interest rate forward contracts. The following information, together with information included in Note 10, Debt and Credit Agreements, and Note 13, Fair Value Measurements, 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 swaps. In 2020, the Company has used derivative financial instrumentsexecuted two forward starting interest rate swaps with an aggregate notional value of $500 million. These swaps were effected to address market risk exposurehedge the benchmark interest rate associated with future interest payments related to fluctuationsthe anticipated refinancing of notes due in interest rates.2027. In 2022, CSX settled a portion equal to $160 million notional value of the cash flow hedges. In 2023, CSX executed two partial settlements equal to $226 million notional value of the cash flow hedges. As of December 2017,31, 2023, these cash flow hedges had an aggregate notional value of $114 million and an asset value of $48 million. As of December 31, 2023, the potential change in fair value of forward starting interest rate swaps resulting from a hypothetical 10% change in interest rates would not be material.

Changes in interest rates could impact the fair value of the Company's fixed-to-floating interest rate swaps. In 2023, CSX doesentered into two separate fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to the Secured Overnight Financing Rate ("SOFR") on a cumulative $250 million of fixed rate outstanding notes which are due in 2033. As of December 31, 2023, the cumulative fair value of these swaps was a $19 million asset. In 2022, CSX entered into five separate fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to SOFR on a cumulative $800 million of fixed rate outstanding notes, which are due between 2036 and 2040. As of December 31, 2023, the cumulative fair value of these swaps was a $107 million liability. As of December 31, 2023, the potential change in fair value of fixed-to-floating interest rate swaps resulting from a hypothetical 10% change in interest rates would not have a material amountbe material.

As of December 31, 2023, CSX has no floating rate notes 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 obligations outstanding,resulting from a hypothetical 10% increase in U.S. Treasury rates, or approximately 40 basis points, is estimated to be $730 million as of December 31, 2023, and therefore fluctuations in$709 million as of December 31, 2022. The underlying fair values of the interest rate would not have a material impactCompany's long-term debt were estimated based on quoted market prices or on the Company's financial condition, results of operations or liquidity.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, 20172023 and December 30, 2016, and2022, the related consolidated statements of income, comprehensive income, cash flows, and changes in shareholders’ equity and cash flows for each of the three fiscal years in the period ended December 31, 2017,2023 and the related notes (collectively referred to as the “financial“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company at December 31, 20172023 and December 30, 2016,2022, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2023, in conformity with U.S. generally accepted accounting principles.


We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017,2023, 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 7, 201814, 2024 expressed an unqualified opinion thereon.


Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.


We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.


Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosure to which it relates.

Depreciation Policies for Assets Utilizing the Group-Life Method
Description of the Matter
As of December 31, 2023, assets depreciated under the group-life method comprised 84% of total gross fixed assets of $50.3 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 conducted by a third-party specialist and analyzed by the Company’s management 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. In years when depreciation studies are not performed, annual data reviews are conducted by a third-party specialist and analyzed by the Company’s management to review the asset service lives. For road and track assets and equipment assets, the most recent depreciation studies were performed in 2020 and 2022, respectively. These studies were evaluated by the Company’s management in the current year through an annual data review.

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 that could impact the estimated useful lives determined in the most recent depreciation studies 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 performed by the Company’s third-party specialist and reviewed by management; 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 reviewed by management in determining if any changes were necessary to the estimated useful lives and salvage values resulting from the annual data reviews.

We compared the assumptions 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 recalculated the current year depreciation rates.



We have served as the Company’s auditor since 1981.

NOTE 1.  Nature of Operations and Significant Accounting Policies, continued


Fiscal Year
ThroughThe Company's fiscal periods are based upon the second quarter 2017, CSX followed a 52/53 week fiscal reporting calendar with the last day of each reporting period ending on a Friday. The 52/53 week calendar allowed for every quarter and year to be of equal duration, 13 weeks and 52 weeks, respectively. To maintain this calendar, every fifth or sixth year, an extra week was added to the fourth quarter and year, making the reporting periods 14 weeks and 53 weeks, respectively. In 2016, the fourth quarter and fiscal year included this extra week.

On July 7, 2017, the Board of Directors of CSX approved a change in the fiscal reporting calendar from a 52/53 week year ending on the last Friday of December to a calendar year ending on December 31 each year, effective beginning with fiscal third quarter 2017. Related to the change in the fiscal calendar:

Fiscal year 2017 (December 31, 2016 through December 31, 2017) contained 366 days, and fiscal year 2016 (December 26, 2015 through December 30, 2016) contained 371 days
Fiscal first quarter 2017 (December 31, 2016 through March 31, 2017) contained 91 days, and fiscal first quarter 2016 (December 26, 2015 through March 25, 2016) contained 91 days
Fiscal second quarter 2017 (April 1, 2017 through June 30, 2017) contained 91 days, and fiscal second quarter 2016 (September 24, 2016 through December 30, 2016) contained 91 days
Fiscal third quarter 2017 (July 1, 2017 through September 30, 2017) contained 92 days, and fiscal third quarter 2016 (June 25, 2016 through September 23, 2016) contained 91 days
Fiscal fourth quarter 2017 (October 1, 2017 through December 31, 2017) contained 92 days, and fiscal fourth quarter 2016 (September 24, 2016 through December 30, 2016) contained 98 days
This change did not materially impact comparability of the Company’s financial results for fiscal year 2016 and fiscal year 2017. Accordingly, the change to a calendar fiscal year was made on a prospective basis and operating results for prior periods have not been adjusted. The Company is not required to file a transition report because this change is not deemed a change in fiscal year for purposes of reporting subject to Rule 13a-10 or Rule 15d-10 of the Securities Exchange Act of 1934 as the new fiscal year commenced with the end of the prior fiscal year end and within seven days of the prior fiscal year end.year. Except as otherwise specified, references to full years indicate CSX’s fiscal years ended on December 31, 20172023, December 31, 2022, and December 30, 2016.31, 2021.
    
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 Conrail or Affiliates and Other Companies on the consolidated balance sheets.

Revenue and Expense Recognition
The Company recognizes freight revenue using Free-On-Board Origin pursuant to the Revenue Recognition Topic in the Accounting Standards Codification ("ASC").  Accounting guidance in this topic provides for the allocation of revenue between reporting periods based on relative transit time in each reporting period.  Expenses are recognized as incurred.
The certain key estimates included in the recognition and measurement of revenue and related accounts receivable under the policies described above 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, billing discounts and bad debts or to accounts receivable for allowances for doubtful accounts;
adjustments to revenue for overcharge claims filed by customers, which are based on historical cash paid to customers for rate overcharges as a percentage of total billing;
incentive-based refunds to customers, which are primarily based on customers achieving certain volume thresholds, are recorded as a reduction to revenue on the basis of management’s best estimate of the projected liability (this estimate is based on historical activity, current volume levels and forecasted future volume).

New Accounting Pronouncements
In May 2017,March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") Compensation - Stock Compensation: Scope2020-04, Facilitation of Modification Accounting, which provides claritythe Effects of Reference Rate Reform on what changes to share-based awards are considered substantive and require modification accounting to be applied. This updateFinancial Reporting. As the London Interbank Offered Rate ("LIBOR") is required beginning with first quarter 2018 and should be applied prospectively to award modifications after the effective date. The Company early adoptedno longer available as of July 2023, this standard update in second quarter 2017provides practical expedients for contract modifications made as part of the transition from LIBOR to alternative reference rates. The guidance was effective upon issuance and will apply it prospectivelyat present can generally be applied through December 31, 2024. The Company applied the practical expedient to any award modifications after the adoption date.its forward starting interest rate swaps effective June 30, 2023. See Note 10, Debt and Credit Agreements, for additional information. The Company does not regularly modifyhave any other contracts that are affected by the termstransition from LIBOR.

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures. This standard update requires additional interim and conditionsannual disclosures about a reportable segment’s expenses, even for companies with only one reportable segment. The Company is required to adopt the guidance for its 2024 annual report filed on Form 10-K, though early adoption is permitted.

In March 2017,December 2023, the FASB issued ASU Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, whichrequires that only the service cost component of net periodic benefit costs be recorded as compensation cost in the operating expense section of the income statement.

Beginning in first quarter 2018, only the service cost will be recorded within labor and fringe expense, and the other components of net benefit costs will be recorded in other income. The retrospective impact of adoption will be an increase in operating income for the prior years presented as the other components were a net expense.

In March 2017, the FASB issued ASU Simplifying the Test for Goodwill Impairment, which eliminates step two, the calculation of the implied fair value of goodwill, from the goodwill impairment test. Impairment will be quantified in step one of the test as the amount by which the carrying amount exceeds the fair value.

NOTE 1.Nature of Operations and Significant Accounting Policies, continued

In May 2014, the FASB issued ASU Revenue from Contracts with Customers, which supersedes previous revenue recognition guidance. The new standard requires that a company recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration the company expects to receive in exchange for those goods or services. Companies will need to use more judgment and estimates than under the guidance currently in effect, including estimating the amount of variable revenue to recognize over each identified performance obligation. Additional disclosures will be required to help users of financial statements understand the nature, amount and timing of revenue and cash flows arising from contracts. CSX will adopt this standard update in first quarter 2018 using a modified retrospective method of adoption.
The FASB has also issued several amendments to the revenue standard, including clarification on accounting for principal versus agent considerations (i.e., reporting gross versus net), licenses of intellectual property and identifying performance obligations. These amendments do not change the core principle of the standard, but provide clarity and implementation guidance.

The Company is currently finalizing its review of the impact of adopting this new guidance and has developed a comprehensive implementation plan. In-depth reviews of commercial contracts have been completed and changes to processes and internal controls to meet the standard’s reporting and disclosure requirements have been identified and are being implemented. Adoption of this standard update will not materially impact the Company's financial condition, results of operations or liquidity. Freight revenue will continue to be recognized ratably over transit time. Additionally, the disaggregated revenue information required to be disclosed under this standard update is similar to the information currently included in the Results of Operations section of Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

In February 2016, the FASB issued ASU, Leases, which will require lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability, and lessors to recognize a net lease investment. Additional qualitative and quantitative disclosures will also be required. This standard update is effective for CSX beginning with the first quarter 2019 and will be adopted using a modified retrospective method. Changes to processes and internal controls to meet the standard’s reporting and disclosure requirements have been identified and are being implemented. Software has been implemented that will assist in the recognition of additional assets and liabilities to be included on the balance sheet related to leases currently classified as operating leases with durations greater than twelve months, with certain allowable exceptions. The Company continues to evaluate the expected impact of this standard update on disclosures, but does not anticipate any material changes to operating results or liquidity.

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, environmental and legal reserves (see Note 5, Casualty, Environmental and Other Reserves);
pension and post-retirement medical plan accounting (see Note 8, Employee Benefit Plans);
depreciation policies for assets under the group-life method (see Note 6, Properties); and
income taxes (see Note 11, Income Taxes).

Other Items
Management Workforce Reduction
Through an involuntary separation program with enhanced benefits to further its strategic objectives, CSX reduced its management workforce by approximately 950employees during 2017. The Company has been focused on driving efficiencies through process improvement and responding to business mix shifts. These management reductions were designed to further streamline general and administrative and operating support functions to speed decision making and further control costs. In April 2017, the involuntary separation program was essentially completed. This program extends separation benefits for certain members of management that could result in additional charges through first quarter 2018. Accordingly, additional charges were incurred under the program throughout the year, including charges related to the separation of senior executives during fourth quarter 2017. The majority of separation benefits are being paid from general corporate funds while certain benefits are being paid through CSX’s qualified pension plans.

Executive Retirements
In first quarter 2017, the Company's former Chief Executive Officer, Michael J. Ward, and President, Clarence W. Gooden, announced their retirements, and the terms of their unvested equity awards were modified to permit prorated vesting through May 31, 2018. The lump-sum payments of their non-qualified pension benefits also resulted in a settlement charge in fourth quarter 2017.

Reimbursement Arrangements
In June 2017, the Company and the Company's former President and Chief Executive Officer, E. Hunter Harrison, executed a letter agreement providing for certain reimbursement arrangements. Pursuant to the letter agreement, the Company made a reimbursement payment to MR Argent Advisor LLC ("Mantle Ridge") of $55 million for funds previously paid to Mr. Harrison by Mantle Ridge. Further, the Company assumed Mantle Ridge’s obligation to pay Mr. Harrison, prior to March 15, 2018, a lump sum cash amount of $29 million in respect of other forfeited compensation from his previous employer, Canadian Pacific Railway Limited. This $29 million payment was made to his estate following his death in December 2017. The Company also assumed Mantle Ridge’s tax indemnification obligations to Mr. Harrison, which was intended to allow Mr. Harrison to remain in the same after-tax position as if he had not: (i) forfeited such compensation and benefits earned from CP; and (ii) received $55 million from Mantle Ridge.

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 were 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.

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.

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 and stock options 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 or, in certain circumstances, byDirectors. Awards to the Chief Executive Officer forare 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 the Company’sCSX'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. Alternatively, expense is recognized upon death or over an accelerated service period for 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 and its related income tax benefit isare shown in the table below. The year over year increase in expense related to performance unitsIncome tax benefits include impacts from option exercises and stock options is primarily due to modifications to the termsvesting of awards (see Equity Award Modificationsbelow) and higher expected award payouts.other equity awards.

Long-term Incentive Plans
The objective of the CSX Long-term Incentive Plans (“LTIP”) were adopted under the 2010 CSX Stock and Incentive Award Plan. The objective of these plans is to motivate and reward certain employees for achieving and exceeding certain financial goals. The 2023-2025, 2022-2024, and 2021-2023 LTIPs were adopted under the 2019 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. In 2015, 2016 and 2017, target performance units were granted to certain employees under threeseparate LTIP plans covering three-year cycles: the 2015-2017 (“2015-2017 LTIP”), 2016-2018 (“2016-2018 LTIP”) and 2017-2019 (“2017-2019 LTIP”) plans (collectively, the “plans”).

The key financial targets for the plans will be based on the achievement of goals related to both operating ratio and return on assets (tax-adjusted operating income divided by net property) excluding certain items as disclosed in the Company's financial statements. The three-year cumulative operating ratio and average return on assets over the performance period will each comprise 50% of the payout and are measured independently of the other. The plans state that payouts for certain executive officers are subject to downward adjustment by up to 30% based upon total shareholder return relative to specified comparable groups.

In 2023, 2022 and 2021, target performance units were granted to certain employees under threeseparate LTIP plans covering three-year cycles: the 2023-2025 ("2023-2025 LTIP"), the 2022-2024 ("2022-2024 LTIP"), and the 2021-2023 ("2021-2023 LTIP"). 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 2023-2025 and 2022-2024 LTIP plan, the average annual operating income growth percentage and Economic Profit (CSX Cash Earnings or CCE), in each case excluding non-recurring items as defined in the plan, 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. As defined under the plan, Economic Profit incentivizes strategic investments earning more than the required return and is calculated as CSX’s gross cash earnings (after-tax adjusted EBITDA) minus the long-term average cost of capital on gross operating assets.

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 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 2023, 2022 and 2021 were calculated primarily using a Monte-Carlo simulation model with the following weighted-average assumptions:

The risk-free interest rate assumptions reflect the U.S. Treasury yield curve in effect at the time of grant. The annualized volatility is based on observed historical volatility of daily stock returns for the three-year period preceding the grant date. The expected life is calculated using the remainder of the performance period.

Stock Options
Stock options in 2023, 2022 and 2021 were primarily granted in 2016 and 2017 along with the corresponding LTIP plans, and to certain members of management in 2015. Under this program,plans. With these grants, 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). The optionsOptions granted become exercisable afterin equal installments on the anniversary of the grant date over a three-year vesting period and(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-MertonBlack-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 6.56.0 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 (three year cliff) and contractual term (10 years).

On March 6, 2017, the Company granted 9 million stock options to former CEO E. Hunter Harrison at a fair value of $12.88 per option. These options were granted with a ten-year term and an exercise price equal to the closing market price of the underlying stock on the date of grant. Half of the options, or 4.5 million, were to vest on Mr. Harrison's service anniversary in equal annual installments over four years. The other half were to vest based on achievement of performance targets related to both operating ratio and earnings before interest, taxes, depreciation and amortization adjusted for certain items. Upon his death on December 16, 2017, all of Mr. Harrison's 9 million options were forfeited.

The terms of performance units, restricted stock units and stock options granted as part of the Company’s long-term share-based compensation plans typically require participants to be employed through the final day of the respective performance or vesting periods as applicable, except in the case of death, disability or retirement. As part of an enhanced severance benefit under the management streamlining and realignment initiative discussed in Note 1, unvested performance units, restricted stock units and stock options for separated employees not eligible for retirement were permitted to vest on a pro-rata basis.

Additionally, the terms of unvested equity awards for the former Chief Executive Officer, Michael J. Ward, and President, Clarence W. Gooden, were modified prior to their retirements on March 6, 2017 to permit prorated vesting through May 31, 2018. The terms were modified in exchange for each agreeing to serve in an advisory capacity upon request until May 31, 2017, and waiving various rights and claims, including the cancellation of their respective change of control agreements with the Company.

Restricted Stock Grants
Restricted stock grants consist of units and awards, each equivalent to one share of CSX stock. Restricted stock units are primarily issued along with corresponding LTIP plans and vest three years after the date of grant (three-year cliff) or on the annual anniversary of the grant date over a vesting period (three-year graded). Separately, restricted stock awards generally vest over an employment period of up to five years. These awards are time-based and not based upon CSX’s attainment of operational targets. Participants receive cash or stock dividend equivalents on these shares, depending on the grant. Restricted stock grant and vesting information is summarized as follows:

These liabilities are accrued when probable and reasonably estimable and probable 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 $228 million and $229 million for 2017and 2016, respectively, represent accruals for personal injury, occupational disease and occupational injury claims.claims primarily related to railroad operations. Casualty reserves include liabilities assumed as a result of the Company's acquisition of Pan Am in 2022. The Company's self-insured retention amount for thesecasualty claims is $50$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. Most of the Company's casualty claims relate to CSXT unless otherwise noted below. 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. It isclaims based largely on CSXT's historical claims and settlement experience.

During 2017 and 2015, there were no significant changes in estimate recorded to adjust casualty reserves. As a direct These analyses did not result of improvements in safety in recent years, the Company has experienced a downward trend in the severity of injuries, which has resulted in a decrease inmaterial adjustment to the estimate of costs per incident. During 2016, the Company reduced casualty reserves, primarily personal injury reserves, by $28 million, resulting in an after-tax effect on earnings from continuing operations and net earnings of $18 million and an after-tax effect on earnings per share of $0.02. The personal injury reserve reductions were included in materials, supplies2023, 2022 or 2021.

Occupational
Occupational reserves represent liabilities for occupational disease and injury claims. Occupational disease claims arise primarily from allegations of exposure to asbestos in the workplace. Occupational injury claims arisearising from allegations of exposure to certain other materials in the workplace such(such as solvents, soaps, chemicals (collectively referred to as “irritants”) and diesel fuels (like exhaust fumes), past exposure to asbestos or allegations of chronic physical injuries resulting from work conditions such(such as repetitive stress injuries.injuries). 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. There were no material adjustments to the occupational reserve in 2023, 2022 or 2021.


Environmental
Environmental reserves were $90 million and $95 million for 2017and2016, 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 214230 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. Environmental reserves include liabilities assumed as a result of the Company's acquisition of Pan Am in 2022 and Quality Carriers in 2021.


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.

NOTE 5.  Casualty, Environmental and Other Reserves, continued

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 themanagement's review process, the Company hasamounts have been recorded amounts 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 materials, suppliespurchased 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 of $56 million and $50 million for 2017 and 2016, respectively, include liabilities for various claims, such as automobile, property, automobilegeneral liability, workers' compensation and general liability. Also included in other reserves are longshoremen disability claims related toclaims. Other reserves include liabilities assumed as a previously owned international shipping business (these claims areresult of the Company's acquisition of Pan Am in runoff) as well as claims for current port employees.2022 and Quality Carriers in 2021.

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 GAAPUnited States generally accepted accounting principles ("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, andwhich is primarily completed by CSXT employees, as well as 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.


The primaryLabor is a significant cost in self-constructed track replacement work is labor.work. CSXT engineering employees directly charge their labor to the track replacement project (the capitalized depreciable property). TheseIn 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. ThroughAs a component of the depreciation study for road and track assets, management performs an analysis of CSXT’slabor costs related to the self-constructed track replacement process,work, which includes direct observation of track replacement processes. Through this analysis, CSX determined that approximately 20% of labor costs associated with track material installationreplacement is related to the deconstruction of old track, for which certain elements are expensed, and 80% is associated with the installation of new track.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 purchase costspurchases of locomotives and freight cars as well as certain equipment leases that are considered to be capital leases in accordance with the Leases Topic in the ASC. In addition, costs to modify or rebuild these assets, which 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%84% of total fixed assets of $44$50.3 billion on a gross basis as of December 2017.2023. The remaining depreciable assets of the Company, including non-railroad assets and assets under capitalfinance 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 LifeDepreciation Studies
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 assumptions regardingmethods 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,Surface Transportation Board ("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. In 2016, the

The Company completed a depreciation study for its equipment assets. The Company plans to complete the next depreciation study for equipment assets in 2019 and road and track assets in 2020.2020 and for equipment assets in 2022, both of which resulted in changes to accumulated depreciation, service lives, salvage values, and other related factors for certain assets. The 2022 equipment study resulted in an increase in annual depreciation expense of approximately $80 million primarily due to deferred losses on assets depreciated using the group-life method. A depreciation study was not performed in 2023.

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 utilizesretires assets on a first-in, first-out approachstatistical curve relative to asset retirements.the age of the assets. 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.

Item 8. Financial Statements and Supplementary Data

NOTE 6.  Properties, continued


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 normally 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 2017, 2016,2023, 2022 or 2015.2021, as no sales met the criteria described above.

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. In 2017, impairmentImpairment expense of $25$2 million was recorded in materials, supplies2023, $4 million in 2022, and other expense$2 million in 2021 was primarily due to the discontinuation of certain in-progress projects.

Government Assistance
The Company is a party to contracts with recipients and subrecipients of awards from federal, state and local governmental agencies. These contracts meet the disclosure requirements under ASU 2021-10, Disclosure by Business Entities about Government Assistance, which the Company adopted effective year end 2022. These awards are typically in the form of cash for purposes of making improvements to the rail network as part of public safety, corridor expansion or 2015.economic revitalization initiatives. The awarding agency generally specifies how the awards are to be spent by the recipients and may include limited conditions requiring return of the assistance.



Government funding received or receivable related to a property asset is netted with the cost of the asset in properties on the consolidated balance sheet, and the net asset is subject to depreciation. Any amounts owed by the government entity are recorded within accounts receivable until reimbursed. For the years ended December 31, 2023, and December 31, 2022, the total amounts received under contracts with government entities to improve the rail network was $84 million and $49 million, respectively. Non-freight accounts receivable related to these government projects was $57 million and $34 million as of December 31, 2023, and December 31, 2022, respectively.

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, including a significant operating lease with the State of Georgia for approximately 137 miles of right-of-way with integral equipment for a term of 50 years with an annual 2.5% increase. 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 2023, 2022 or 2021.

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 in between 2003 or thereafter, 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. The CSX Pension Plan, the largest plan based on benefit obligation, was closed to new participants beginning in 2020.


In additionThe Company engages independent actuaries to compute the amounts of liabilities and expenses relating to these plans subject to the assumptions that the Company sponsors a post-retirement medical plandetermines are appropriate based on historical trends, current market rates and a life insurance planfuture 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 provide certain benefitspopulation forward to full-time, salaried, management employees hired prior to 2003, upon their retirement if certain eligibility requirements are met. Eligible retirees who are age 65 years or older (Medicare-eligible) are covered by a health reimbursement arrangement, which is an employer-funded account that can be used for reimbursementthe end of eligible medical expenses. Eligible retirees younger than 65 years (non-Medicare eligible) are covered by a self-insured program partially funded by participating retirees.the year.

(a) For pension plans, the other category consists mostly of terminated but vested former employees.  For post-retirement plans, the other category consists of employees on long-term disability that have not yet retired.

The benefit obligation for these plans represents the liability of the Company for current and retiredformer 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 gopay-as-you-go basis. No qualified pension plan contributions were made during 20152023, 2022 and 2017. Although no contributions to the Company's qualified pension plans were required, CSX made voluntary contributions totaling $250 million during 2016.2021. No contributions to the Company's qualified pension plans are expected in 2018.2024.

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 IRCInternal 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. Amounts related to pension and post-retirement benefits recorded in other long-term assets, labor and fringe benefits payable and other long-term liabilities on the balance sheet are as follows:

As a result of the management workforce reduction programs initiated in 2017, $85 million in charges were incurred related to special termination benefits, curtailment and settlement changes. In 2017, the Company recorded special termination pension benefits of $56 million and remeasured the pension and other post-retirement benefits assets and obligations and recorded a curtailment loss of $4 million and $13 million, respectively, in restructuring charge on the income statement.


Pension settlement losses (gains) were recognized as a result of lump-sum payments to retirees exceeding the sum of the plan’s service and interest cost. The Company recorded an $11 million net settlement loss in 2017, of which a $12 million loss resulted from the retirements of former executives and is reported in restructuring charge on the income statement. The other settlement gains in 2017, 2016 and 2015 were from one of the Company’s qualified pension plans with insignificant balances and were recorded in labor and fringe expense on the income statement.

The special termination benefits in 2015 resulted from the management workforce reduction programs initiated in 2014. For additional information regarding the management workforce reductions, see Note 1, Nature of Operations and Significant Accounting Policies.

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 and economists 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. 


Beginning in 2017, theThe Company measuredmeasures 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 instead of a single weighted-average discount rate approach, which has been used in prior years.

The Company made this change to improve the correlation between projected pension and post-retirement benefit obligation cash flows and the corresponding spot discount rates and to provide a more precise measurement of service and interest costs. 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 obligations are applied to the relevant projected cash flows at the relevant maturity. The use of the spot rate approach does not affect the measurement of the pension and post-retirement benefits obligations. The Company accounted for this change on a prospective basis as a change in accounting estimate. For 2017, the adoption of the spot rate approach decreased the Company's net pension and post-retirement benefits expense by approximately $25 million compared to the approach applicable in prior years.

Post-retirement Medical Plan
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. The impact of the health care cost trend rate is immaterial to theaccumulated post-retirement benefit costobligation related to this plan was $56 million and obligation due$61 million, respectively, as of December 31, 2023 and 2022.

Expenses in 2023, 2022 and 2021 related to this plan were not material.


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 $40$11 million, $35$13 million and $32$21 million in 2017, 20162023, 2022 and 2015,2021, 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 $39 million, $35 million, $28 million and $36$29 million for 2017, 20162023, 2022 and 2015,2021, 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 two multi-employer pension plans. These plans provide defined benefits to retired participants.Both of these pension plans are in Pension Protection Act zone “red”, meaning they are at least 65% underfunded.Formal rehabilitation plans have been adopted. Based on information provided to the Company from the administrators of these plans, Quality Carriers’ portion of the contingent liability in the event of a full withdrawal or termination from these plans is estimated to be approximately $334 million. Of this amount, $328 million relates to the Central States Southeast and Southwest Areas Pension Plan and is based on information as of December 31, 2022, which is the latest information available at the date the financial statements were issued.The Company does not currently intend to withdraw from any of these multi-employer pension plans.

Interest Rate Derivatives
Fair Value Hedges
In fourth quarter 2023, CSX entered into two separate fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to the Secured Overnight Financing Rate ("SOFR") on a cumulative $250 million of fixed rate outstanding notes which are due in 2033. The cumulative fair value of these swaps, which is included in other long-term assets on the consolidated balance sheet, was an asset of $19 million as of December 31, 2023.

In first quarter 2022, CSX entered into five separate fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to the SOFR on a cumulative $800 million of fixed rate outstanding notes which are due between 2036 and 2040. The cumulative fair value of these swaps which is included in other long-term liabilities on the consolidated balance sheet, was a liability of $107 million and $118 million as of December 31, 2023, and December 31, 2022, respectively.

The 2022 swaps will expire in 2032 and the 2023 swaps will expire in 2033. If settled early, the remaining cumulative fair value adjustment to the hedged notes will be amortized over the remaining life of the associated notes. The cumulative adjustment to the hedged notes is included in long-term debt on the consolidated balance sheet as shown in the following table.

Cash Flow Hedges
In 2020, the Company executed forward starting interest rate swaps, classified as cash flow hedges, with 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 HedgingTopic in the ASC, the Company has designated these swaps as cash flow hedges. Under the terms of the Adjustable Interest Rate (LIBOR) Act, the reference rate on the swaps were automatically replaced with daily compounded SOFR plus the fallback spread on July 1, 2023, the LIBOR replacement date.

In fourth quarter 2022, CSX settled a portion equal to $160 million notional value of the aggregate $500 million cash flow hedges, which resulted in CSX receiving a cash payment of $52 million included in other operating activities on the consolidated cash flow statement. In second quarter 2023, CSX executed a partial settlement equal to $113 million notional value of the cash flow hedges, which resulted in CSX receiving a cash payment of $44 million. In third quarter 2023, CSX partially settled an additional $113 million notional value of the cash flow hedges and received a cash payment of $51 million included in other operating activities on the consolidated cash flow statement. The unsettled aggregate notional value of these swaps was $114 million and $340 million as of December 31, 2023, and December 31, 2022, respectively.

As of December 31, 2023 and 2022, the asset value of the forward starting interest rate swaps was $48 million and $127 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. The unrealized gain associated with the settled portion of the hedges will continue to be classified in AOCI until the associated debt instrument is issued in the future. Unless settled early, the remainder of 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 amounts related to the hedge, recorded net of tax in other comprehensive income, are summarized in the table below.

Credit Facilities
In February 2023, CSX hasreplaced its existing $1.2 billion unsecured revolving credit facility with a $1new $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 SOFR or an agreed-upon replacement reference rate, plus a spread that depends upon CSX's senior unsecured debt ratings.

Revenue Recognition
The Company derives incomegenerates revenue from itemsrail 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 2023 Form 10-K p.98

NOTE 11. Revenues, continued

The average transit time to complete a rail shipment is between 2 to 7 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 considered operating activities. Income from these itemscompleted at the reporting date is reported net of related expense. Miscellaneous income (expense) includes investment gains and losses, certain non-operating equity earnings or losses and other non-operating activities and may fluctuate due to timing. 

As substantially all real estate activities are focused on supporting railroad operations, beginning in first quarter 2017, all results of these activities are included in operating income. Previously, these activities were classified as operating or non-operatingallocated based on the naturerelative 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, which 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 activity.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 demurrage, intermodal storage and equipment usage, and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.

During 2023, 2022 and 2021, revenue recognized from performance obligations related to prior periods 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.

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 2023, 2022, and 2021. Federal examinations of original federal income tax returns for all years through 2020 are resolved.

As of December 2023 and 2022, the Company had approximately $19 million and $18 million, respectively, of total unrecognized tax benefits as a result of uncertain tax positions. Net tax benefits of $15 million and $14 million as of December 2023 and 2022, respectively, could favorably impact the effective income tax rate in each year. The Company does not expect that unrecognized tax benefits as of December 2023 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 year ended December 2023.
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 2023 or 2022. Additionally, expenses from changes to the reserves for interest and penalties were not material in 2023, 2022 or 2021.

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 fixed income mutual funds, corporate bonds and government securities. The fixed income mutual funds are valued at the net asset value of shares held based on quoted market prices determined in an active market, which are Level 1 inputs. The corporate bonds and government securities are valued using broker quotes that utilize observable market inputs, which are Level 2 inputs. Unrealized losses as of December 31, 2023 and December 31, 2022 were not material. The Company believes any impairment of investments held with gross unrealized losses to be temporary and not the result of credit risk.

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 tax computed at statutoryscheduled contractual debt payments and maturities. These market rates is presented inare provided by the table below. With the enactmentsame third party. All of the Tax Cuts and Jobs Act (the "Act" or "tax reform") on December 22, 2017,inputs used to determine the fair value of the Company's 2017long-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 results included a $3.5 billion, or $3.81 per share, non-cash reduction in income tax expense, primarily resulting from revaluing the Company's net deferred tax liabilities to reflect the recently enacted 21% federal corporate tax rate effective January 1, 2018. These estimates are based on the Company's initial analysisinstruments, size of the Actinstrument, cash flow projections and may be adjusted in future periods as required.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 Act has significant complexity and implementation guidance from the Internal Revenue Service, clarificationsfair value of state tax law and the completiona company's debt is a measure of the Company’s 2017 tax return filings could all impact these estimates. The Companyits current value under present market conditions. It does not believe potential adjustments in future periods would materially impact the Company's financial condition or results of operations. The provisions of the Act related to foreign earnings will not impact CSX.

The Company's affiliates also revalued their deferred tax liabilities to reflect the lower federal corporate tax rate, which resulted in the Company recognizing a benefit of $142 million, or $0.10 per share after-tax, in equity earnings of affiliates, which is included in operating income. (See additional discussion over equity earnings of affiliates in Note 12, Related Parties and Affiliates.)

In addition to the tax benefit related to tax reform, the Company recorded a 2017 income tax benefit of $21 million primarily as a result of the additional tax benefit associated with vesting of share-based awards, state legislative changes, a change in the apportionment of state taxable income and the related impact on the valuation of deferred taxes, and the settlement of certain state tax matters. In 2016, the Company recorded an income tax expense adjustment of $10 million as a result of a change in the apportionment of state income taxes and the related impact on the valuation of deferred taxes as well as a $7 million tax benefit as a result of federal and state legislative changes. In 2015, the Company recorded a tax benefit of $4 million primarily as a result of federal and state legislative changes as well as the resolution of federal and state tax matters.statements under current accounting rules.

Tax Reform Effect on Equity Earnings of Affiliates
Due to the enactment of tax reform, the Company recognized a benefit of $142 million, or $0.10 per share after-tax, in its equity earnings of affiliates. This benefit was primarily the result of the Company's affiliates (primarily TTX and Conrail) revaluing their deferred tax liabilities to reflect the lower federal corporate tax rate, which favorably impacted their net earnings for 2017. (See additional discussion over tax reform in Note 11, Income Taxes.)

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 and long-term debt. 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 and long-term debt. 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, valued with assistance from a third-party trustee, consist of certificates of deposits, commercial paper, corporate bonds and government securities and are carried at fair value on the consolidated balance sheet per the Fair Value Measurements and Disclosures Topic in the ASC. There are several valuation methodologies used for those assets as described below:

Certificates of Deposit and Commercial Paper (Level 2): Valued at amortized cost, which approximates fair value;

Corporate Bonds and Government Securities (Level 2): Valued using broker quotes that utilize observable market inputs; and

The Company's investment assets are carried at fair value on the consolidated balance sheets as summarized in the following table. All of the inputs used to determine the fair value of the Company's investments are Level 2 inputs. The amortized cost basis of these investments was $91 million and $500 million as of December 31, 2017 and December 30, 2016, respectively.

Certain prior year data has been reclassified to conformAs a result of the acquisition of Pan Am on June 1, 2022, CSX recognized $17 million of goodwill. The goodwill was calculated as the excess of the consideration paid over the fair value of net assets assumed and relates primarily to the current presentation.ability of CSX to extend the reach of its service to a wider customer base over an expanded territory, creating new market prospects and efficiencies. Goodwill recognized in this acquisition is not deductible for tax purposes.


During 2023 and 2022, Quality Carriers completed several acquisitions that were immaterial individually and in aggregate. The acquisitions resulted in the addition of $6 million and $26 million of goodwill in 2023 and 2022, respectively. Other intangible assets recognized as part of these acquisitions were $8 million and $18 million in 2023 and 2022, respectively.

The Company's intangible assets balance primarily relates to intangibles recognized as part of the acquisition of Quality Carriers in 2021. Intangible assets recognized from the acquisition 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.

During the fourth quarter 2023, the Company changed the date of its annual assessment of Goodwill to October 1st for all reporting units. The change in testing date for goodwill is a change in accounting principle, which management believes is preferable as it will create consistency in the Company's goodwill impairment testing procedures across its reporting units. This change was not material to CSX's consolidated financial statements and it did not delay, accelerate, or avoid any potential goodwill impairment charges. No impairment was recorded as a result of the assessment.

Item 9A.  Controls and Procedures


Evaluation of Disclosure Controls and Procedures
As of December 31, 2017,2023, under the supervision and with the participation of CSX's Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), management has evaluated the effectiveness of the design and operation of the Company's disclosure controls and procedures. Based on that evaluation, the CEO and CFO concluded that, as of December 31, 2017,2023, the Company's disclosure controls and procedures were effective at the reasonable assurance level in timely alerting them to material information required to be included in CSX’s periodic SEC reports.


Management's Report on Internal Control over Financial Reporting
CSX’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of the management of CSX, including CSX’s CEO and CFO, CSX conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of December 31, 20172023 based on the 2013 framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, which is also referred to as COSO. Based on that evaluation, management of CSX concluded that the Company’s internal control over financial reporting was effective as of December 31, 2017.2023. 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, 20172023 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, 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.


CSX CORPORATION
PART II


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, continued


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.
