Commitments and Contingencies	Commitments and Contingencies Eastern Ohio Incident Summary On February 3, 2023, a train we operated derailed in East Palestine, Ohio. The derailed equipment included 38 railcars, 11 of which were non-Company-owned tank cars containing hazardous materials. Fires associated with the derailment threatened certain of the tank cars. There was concern about the risk that the content of five of the tank cars carrying vinyl chloride might polymerize, which would have posed the risk of a catastrophic explosion. As a consequence, on February 6, 2023, the local incident commander—in consultation with the incident command that included, among others, federal, state and local officials and Norfolk Southern—opted to conduct a controlled vent and burn of five derailed tank cars, all of which contained vinyl chloride. This procedure involved creating holes in the five tank cars to drain the vinyl chloride into adjacent trenches that had been dug into the ground where such vinyl chloride was then burned, with any material remaining after burning of the vinyl chloride being remediated. The February 3rd derailment, the associated fire, and the resulting vent and burn of the tank cars containing vinyl chloride on February 6th is hereinafter referred to as the “Incident.” In response to the Incident, we have worked to clean the site safely and thoroughly, including those activities described in the Environmental Matters section below with respect to potentially impacted air, soil and water and to monitor for any impact on public health and the environment. We are working with federal, state, and local officials to mitigate impacts from the Incident, including, among other efforts, conducting environmental monitoring and clean-up activities (as more fully described below), and establishing a family assistance center to provide financial support to affected members of the East Palestine and surrounding communities. Financial Impact Although we cannot predict the final outcome or estimate the reasonably possible range of loss with certainty, we have recognized $387 million of expense for costs directly attributable to the Incident, which is presented in “Eastern Ohio incident” on the Consolidated Statements of Income. During the first quarter, our cash expenditures attributable to the Incident were $55 million, which are presented in “Net cash provided by operating activities” on the Consolidated Statement of Cash Flows. The remainder, $332 million, is primarily comprised of our estimates of probable and reasonably estimable liabilities principally associated with environmental matters and legal proceedings, which are discussed in further detail below. While certain costs recorded in the first quarter may be recoverable under our insurance policies in effect at the date of the Incident, no estimate of potential recoveries has yet been recorded. Any amounts recoverable under our insurance policies will be reflected in future periods in which recovery is considered probable. For additional information about our insurance coverage, see “Insurance” below. Environmental Matters – In response to the Incident, we have been working with federal, state, and local officials such as the U.S. Environmental Protection Agency (EPA), the Ohio EPA, and the Pennsylvania Department of Environmental Protection, to conduct environmental response and remediation activities, including but not limited to, air monitoring, indoor air quality screenings, municipal water and private water well testing, residential, commercial, and agricultural soil sampling, surface water and groundwater sampling, re-routing a local waterway around the affected site, capturing and shipping stormwater that enters the impacted derailment site to proper disposal facilities, and excavating and disposing of potentially affected soil at hazardous waste landfills or incinerators. The U.S. EPA issued a Unilateral Administrative Order (UAO) on February 21, 2023, containing various requirements, including the submission of numerous work plans to assess and remediate various environmental media and performance of certain removal actions at the affected site. On February 24, 2023, we submitted to the U.S. EPA our Notice of Intent to Comply with the UAO and are currently cooperating with U.S. EPA as well as the Ohio EPA and Pennsylvania Department of Environmental Protection, pursuant to the UAO and the directives issued thereunder. We are also subject to the following legal proceedings that principally relate to the environmental impact of the Incident: •The U.S. Department of Justice (DOJ) and the U.S. EPA filed a civil complaint (the DOJ Complaint) in the Northern District of Ohio (Eastern Division) seeking injunctive relief, cost recovery and civil penalties for violations of the Clean Water Act and seeking cost recovery under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA); and •The Ohio Attorney General filed a CERCLA lawsuit (the Ohio Complaint) in the Northern District of Ohio (Eastern Division) requesting statutory damages for a variety of tort and environmental claims under CERCLA. In connection with the foregoing items, we recognized $317 million of expense during the first quarter, of which $31 million was paid, related to probable obligations that are reasonably estimable, in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 410-30, “Environmental Obligations.” Our current estimate includes ongoing and future environmental cleanup activities and remediation efforts, governmental oversight costs (including those incurred by the U.S. EPA and the Ohio EPA), and other related costs, including those in connection with the DOJ Complaint (including potential civil penalties related to violations of the Clean Water Act). Our current estimates of future environmental cleanup and remediation liabilities related to the Incident may change over time due to various factors, including but not limited to, the success of current cleanup techniques, the nature and extent of required future cleanup activities, and the extent of governmental oversight, amongst other factors. As clean-up efforts progress and more information is available, including any federal and state requirements, we will review these estimates and revise as appropriate. Legal Proceedings (Non-Environmental) – To date, numerous non-environmental legal actions have been filed with respect to the Incident, including those more specifically set forth below. •There are currently numerous putative class action and individual lawsuits that have been filed, primarily consolidated in the Northern District of Ohio (Eastern Division). The putative class action complaints currently allege numerous claims, including negligence, nuisance, trespass, and medical monitoring, and seek as relief, among other things, compensatory and punitive damages. The putative classes are currently defined by reference to class areas ranging from the evacuation zone up to 100 miles away. Additional multi-plaintiff lawsuits are also pending in the same court and others, such as additional lawsuits pending in the Western District of Pennsylvania brought by local school districts including claims such as negligence, nuisance, trespass, and future health monitoring. No responsive pleadings have yet been filed with respect to these matters (collectively referred to herein as the Incident Lawsuits). In accordance with ASC 450, “Contingencies,” we have recognized a $12 million probable loss in the first quarter with respect to the Incident Lawsuits, which is in addition to $16 million in amounts paid during the first quarter with respect to these matters. •Securities litigation, including a securities class action lawsuit filed in the Southern District of Ohio alleging multiple securities law violations for which no responsive pleading has yet been filed, as well as multiple shareholder demand letters that we have received (collectively, the Shareholder Lawsuits). If and when we conclude that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it will be accrued through a charge to earnings and, if material, disclosed. Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments become known. Because the final outcome of any of these legal proceedings cannot be predicted with certainty, unfavorable or unexpected developments or outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. For legal proceedings where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established but the matter, if potentially material, is disclosed. The reserves established by us during the first quarter do not include any estimate of loss for the following items, for which we believe a loss is either not probable or not reasonably estimable for the reasons noted: (i) the overall cost to us for programs being developed in conjunction with the Ohio Attorney General for affected residents and businesses, which amounts will impact our loss contingency analysis with respect to the Incident Lawsuits described above, namely a healthcare fund, tailored protection for property owners, and programs to protect drinking water over the long term (given the preliminary nature of such discussions), or (ii) any fines or penalties (in excess of the reserves established for Clean Water Act-related civil penalties) that may be imposed as a result of the Incident Inquiries and Investigations, as more specifically set forth and defined below (the outcome of which are uncertain at this time). Additionally, as noted above, amounts recognized during the first quarter do not include potential recoveries from third parties, including the impact of our insurance coverage, which may apply to various Incident-related expenses or liabilities, as more specifically set forth further below (given the preliminary nature of any related discussions with our insurers). Inquiries and Investigations As set forth above, we are subject to inquiries and investigations by numerous federal, state, and local government authorities and regulatory agencies regarding the Incident, including but not limited to, the DOJ and the U.S. EPA, the Ohio EPA, the National Transportation Safety Board (NTSB), the Federal Railroad Administration (FRA), the Occupational Safety and Health Administration, the Ohio Attorney General, and the Pennsylvania Attorney General. Further details regarding the NTSB and FRA investigations are set forth below. We are cooperating with all inquiries and investigations, including responding to civil and criminal subpoenas and other requests for information (the aforementioned inquiries and investigations, as well as the civil and criminal subpoenas are collectively referred to herein as the Incident Inquiries and Investigations). The outcome of any current or future Incident Inquiries and Investigations is uncertain at this time, including any related fines, penalties or settlements. Therefore, our first quarter expenses do not include estimates of the total amount that we may incur for any such fines, penalties or settlements. Subsequent to the Incident, investigators from the NTSB examined railroad equipment and track conditions; reviewed data from the signal system, wayside defect detectors, local surveillance cameras, and the lead locomotive’s event recorder and forward-facing and inward-facing image recorders; and completed certain interviews (the NTSB Investigation). The NTSB issued a preliminary report indicating that one of the cars involved in the derailment appeared to have a wheel bearing in the final stage of overheat failure moments before the derailment. Their preliminary report also indicates that the rail crew was operating the train within our rules; the rail crew operated the train below the track speed limit, the wayside heat detectors were operating as designed; and once the rail crew was alerted by the wayside detector, they immediately began to stop the train. The NTSB’s investigation remains ongoing. Concurrent with the NTSB Investigation, the FRA is also investigating the Incident. Similar in scope to the NTSB Investigation, the FRA is examining railroad equipment, track conditions, hazardous materials train placement and routing, and emergency response (the FRA Incident Investigation). The FRA Incident Investigation may result in the assessment of civil penalties. In addition to the FRA Incident Investigation, the FRA announced on March 7, 2023 that it would conduct a 60-day supplemental safety assessment (the FRA Safety Assessment). The FRA Safety Assessment will review findings from a previously completed 2022 system audit and assess operational elements including, but not limited to: track, signal, and rolling stock maintenance, inspection and repair practices; protection of employees; communications between transportation departments and mechanical and engineering staff; operation control center procedures and dispatcher training. The overall scope of the FRA Safety Assessment is to examine our safety culture. At the conclusion of the FRA Safety Assessment, the FRA will issue a public report which will include its findings and recommended corrective actions. The FRA Incident Investigation and the FRA Safety Assessment remain ongoing. Other Commitments and Contingencies Lawsuits We and/or certain subsidiaries are defendants in numerous lawsuits and other claims relating principally to railroad operations. When we conclude that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to earnings and, if material, disclosed below. While the ultimate amount of liability incurred in any of these lawsuits and claims is dependent on future developments, in our opinion, the recorded liability is adequate to cover the future payment of such liability and claims. However, the final outcome of any of these lawsuits and claims cannot be predicted with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments become known. For lawsuits and other claims where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established but the matter, if potentially material, is disclosed below. We routinely review relevant information with respect to our lawsuits and other claims and update our accruals, disclosures and estimates of reasonably possible loss based on such reviews. In 2007, various antitrust class actions filed against us and other Class I railroads in various Federal district courts regarding fuel surcharges were consolidated in the District of Columbia by the Judicial Panel on Multidistrict Litigation. In 2012, the court certified the case as a class action. The defendant railroads appealed this certification, and the Court of Appeals for the District of Columbia vacated the District Court’s decision and remanded the case for further consideration. On October 10, 2017, the District Court denied class certification. The decision was upheld by the Court of Appeals on August 16, 2019. Since that decision, various individual cases have been filed in multiple jurisdictions and also consolidated in the District of Columbia. We believe the allegations in the complaints are without merit and intend to vigorously defend the cases. We do not believe the outcome of these proceedings will have a material effect on our financial position, results of operations, or liquidity. In 2018, a lawsuit was filed against one of our subsidiaries by the minority owner in a jointly-owned terminal railroad company in which our subsidiary has the majority ownership. The lawsuit alleged violations of various state laws and federal antitrust laws. On January 3, 2023, the court granted summary judgment to us on all of the compensatory claims but denied summary judgment for all equitable relief claims. On January 18, 2023, the court dismissed the federal equitable relief claims, leaving the state equitable relief claims as the sole remaining issue under consideration. On April 19, 2023, the court disposed of all remaining state equitable relief claims. These rulings may be appealed. If appealed, we will continue to vigorously defend the lawsuit and, although it is reasonably possible we could incur a loss in the case, we believe that we will prevail. However, given that litigation is inherently unpredictable and subject to uncertainties, there can be no assurances that the final outcome of the litigation (including any related appeal) will not be material. Until such appeal is final, we cannot reasonably estimate the potential loss or range of loss associated with this matter. Casualty Claims Casualty claims include employee personal injury and occupational claims as well as third-party claims, all exclusive of legal costs. To aid in valuing our personal injury liability and determining the amount to accrue with respect to such claims during the year, we utilize studies prepared by an independent consulting actuarial firm. Job-related personal injury and occupational claims are subject to the Federal Employer’s Liability Act (FELA), which is applicable only to railroads. The variability inherent in FELA’s fault-based tort system could result in actual costs being different from the liability recorded. While the ultimate amount of claims incurred is dependent on future developments, in our opinion, the recorded liability is adequate to cover the future payments of claims and is supported by the most recent actuarial study. In all cases, we record a liability when the expected loss for the claim is both probable and reasonably estimable. Employee personal injury claims – Other than Incident-related matters noted above, the largest component of claims expense is employee personal injury costs. The independent actuarial firm we engage provides quarterly studies to aid in valuing our employee personal injury liability and estimating personal injury expense. The actuarial firm studies our historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences. The actuarial firm uses the results of these analyses to estimate the ultimate amount of liability. We adjust the liability quarterly based upon our assessment and the results of the study. The accuracy of our estimate of the liability is subject to inherent limitation given the difficulty of predicting future events such as jury decisions, court interpretations, or legislative changes. As a result, actual claim settlements may vary from the estimated liability recorded. Occupational claims – Occupational claims include injuries and illnesses alleged to be caused by exposures which occur over time as opposed to injuries or illnesses caused by a specific accident or event. Types of occupational claims commonly seen allege exposure to asbestos and other claimed toxic substances resulting in respiratory diseases or cancer. Many such claims are being asserted by former or retired employees, some of whom have not been employed in the rail industry for decades. The independent actuarial firm provides an estimate of the occupational claims’ liability based upon our history of claim filings, severity, payments, and other pertinent facts. The liability is dependent upon judgments we make as to the specific case reserves as well as judgments of the actuarial firm in the quarterly studies. Our estimate of ultimate loss includes a provision for those claims that have been incurred but not reported. This provision is derived by analyzing industry data and projecting our experience. We adjust the liability quarterly based upon our assessment and the results of the study. However, it is possible that the recorded liability may not be adequate to cover the future payment of claims. Adjustments to the recorded liability are reflected in operating expenses in the periods in which such adjustments become known. Third-party claims – We record a liability for third-party claims including those for highway crossing accidents, trespasser and other injuries, property damage, and lading damage. The actuarial firm assists us with the calculation of potential liability for third-party claims, except lading damage, based upon our experience including the number and timing of incidents, amount of payments, settlement rates, number of open claims, and legal defenses. We adjust the liability quarterly based upon our assessment and the results of the study. Given the inherent uncertainty in regard to the ultimate outcome of third-party claims, it is possible that the actual loss may differ from the estimated liability recorded. Environmental Matters We are subject to various jurisdictions’ environmental laws and regulations. We record a liability where such liability or loss is probable and reasonably estimable. Environmental specialists regularly participate in ongoing evaluations of all known sites and in determining any necessary adjustments to liability estimates. In addition to environmental claims associated with the Incident, our Consolidated Balance Sheets include liabilities for other environmental exposures of $61 million at March 31, 2023 and $66 million at December 31, 2022, of which $15 million is classified as a current liability at the end of both periods. At March 31, 2023 and December 31, 2022, the liability represents our estimates of the probable cleanup, investigation, and remediation costs based on available information at 85 known locations and projects. At March 31, 2023, twenty sites accounted for $49 million of the liability, and no individual site was considered to be material. We anticipate that most of this liability will be paid out over five years; however, some costs will be paid out over a longer period. At eight locations, one or more of our subsidiaries in conjunction with a number of other parties have been identified as potentially responsible parties under CERCLA or comparable state statutes that impose joint and several liability for cleanup costs. We calculate our estimated liability for these sites based on facts and legal defenses applicable to each site and not solely on the basis of the potential for joint liability. As set forth above, with respect to known environmental sites (whether identified by us or by the U.S. EPA or comparable state authorities), estimates of our ultimate potential financial exposure for a given site or in the aggregate for all such sites can change over time because of the widely varying costs of currently available cleanup techniques, unpredictable contaminant recovery and reduction rates associated with available cleanup technologies, the likely development of new cleanup technologies, the difficulty of determining in advance the nature and full extent of contamination and each potential participant’s share of any estimated loss (and that participant’s ability to bear it), and evolving statutory and regulatory standards governing liability. The risk of incurring environmental liability for acts and omissions, past, present, and future, is inherent in the railroad business. Some of the commodities we transport, particularly those classified as hazardous materials, pose special risks that we work diligently to reduce. In addition, several of our subsidiaries own, or have owned, land used as operating property, or which is leased and operated by others, or held for sale. Because environmental problems that are latent or undisclosed may exist on these properties, there can be no assurance that we will not incur environmental liabilities or costs with respect to one or more of them, the amount and materiality of which cannot be estimated reliably at this time. Moreover, lawsuits and claims involving these and potentially other unidentified environmental sites and matters are likely to arise from time to time. The resulting liabilities could have a significant effect on financial position, results of operations, or liquidity in a particular year or quarter. Based on our assessment of the facts and circumstances now known, we believe we have recorded the probable and reasonably estimable costs for dealing with those environmental matters of which we are aware. Further, we believe that it is unlikely that any known matters, either individually or in the aggregate, will have a material adverse effect on our financial position, results of operations, or liquidity. Labor Agreements Approximately 80% of our railroad employees are covered by collective bargaining agreements with various labor unions. Pursuant to the Railway Labor Act, these agreements remain in effect until new agreements are reached, or until the bargaining procedures mandated by the Railway Labor Act are completed. Moratorium provisions in the labor agreements govern when the railroads and unions may propose changes to the agreements. We largely bargain nationally in concert with other major railroads, represented by the National Carriers’ Conference Committee. The latest round of national bargaining concluded in December 2022, when agreements were either ratified or enacted through legislative action for all twelve of our unions. We are currently participating in additional discussions (none of which carry the risk of a work stoppage) with several of our unions to conclude the implementation of these national agreements. With the conclusion of national bargaining, neither party can compel mandatory bargaining around any new proposals until November 1, 2024. In addition, we understand the imperative to continue improving quality of life for our craft employees and are actively engaged in voluntary local discussions with our unions on this important issue. Insurance We purchase insurance covering legal liabilities for bodily injury and property damage to third parties. This insurance provides coverage above $75 million and below $800 million (or up to $1.1 billion for specified types of pollution releases) per occurrence and/or policy year. In addition, we purchase insurance covering damage to property owned by us or in our care, custody, or control. This insurance covers approximately 82% of potential losses above $75 million and below $275 million per occurrence and/or policy year. Our ability to recoup any of the foregoing amounts under our insurance coverage, including any amounts that may be recoverable with respect to the Incident, is subject to certain conditions, including but not limited to our insurers’ reservation of rights to further investigate and contest coverage, the express restrictions and sub-limits of coverage, and various policy exclusions, including those for some governmental fines or penalties, as well as potential coverage disputes over payments we make as part of our effort to mitigate the impact to the community and affected residents. We are working with our insurers to confirm applicable coverage with respect to the Incident, but no estimate for potential insurance recovery has been accrued at this time.

On February 3, 2023, a train we operated derailed in East Palestine, Ohio. The derailed equipment included 38 railcars, 11 of which were non-Company-owned tank cars containing hazardous materials. Fires associated with the derailment threatened certain of the tank cars. There was concern about the risk that the content of five of the tank cars carrying vinyl chloride might polymerize, which would have posed the risk of a catastrophic explosion. As a consequence, on February 6, 2023, the local incident commander—in consultation with the incident command that included, among others, federal, state and local officials and Norfolk Southern—opted to conduct a controlled vent and burn of five derailed tank cars, all of which contained vinyl chloride. This procedure involved creating holes in the five tank cars to drain the vinyl chloride into adjacent trenches that had been dug into the ground where such vinyl chloride was then burned, with any material remaining after burning of the vinyl chloride being remediated. The February 3rd derailment, the associated fire, and the resulting vent and burn of the tank cars containing vinyl chloride on February 6th is hereinafter referred to as the “Incident.”

In response to the Incident, we have worked to clean the site safely and thoroughly, including those activities described in the Environmental Matters section below with respect to potentially impacted air, soil and water and to monitor for any impact on public health and the environment. We are working with federal, state, and local officials to mitigate impacts from the Incident, including, among other efforts, conducting environmental monitoring and clean-up activities (as more fully described below), and establishing a family assistance center to provide financial support to affected members of the East Palestine and surrounding communities.

Although we cannot predict the final outcome or estimate the reasonably possible range of loss with certainty, we have recognized $387 million of expense for costs directly attributable to the Incident, which is presented in “Eastern Ohio incident” on the Consolidated Statements of Income. During the first quarter, our cash expenditures attributable to the Incident were $55 million, which are presented in “Net cash provided by operating activities” on the Consolidated Statement of Cash Flows. The remainder, $332 million, is primarily comprised of our estimates of

While certain costs recorded in the first quarter may be recoverable under our insurance policies in effect at the date of the Incident, no estimate of potential recoveries has yet been recorded. Any amounts recoverable under our insurance policies will be reflected in future periods in which recovery is considered probable. For additional information about our insurance coverage, see “Insurance” below.

Environmental Matters – In response to the Incident, we have been working with federal, state, and local officials such as the U.S. Environmental Protection Agency (EPA), the Ohio EPA, and the Pennsylvania Department of Environmental Protection, to conduct environmental response and remediation activities, including but not limited to, air monitoring, indoor air quality screenings, municipal water and private water well testing, residential, commercial, and agricultural soil sampling, surface water and groundwater sampling, re-routing a local waterway around the affected site, capturing and shipping stormwater that enters the impacted derailment site to proper disposal facilities, and excavating and disposing of potentially affected soil at hazardous waste landfills or incinerators. The U.S. EPA issued a Unilateral Administrative Order (UAO) on February 21, 2023, containing various requirements, including the submission of numerous work plans to assess and remediate various environmental media and performance of certain removal actions at the affected site. On February 24, 2023, we submitted to the U.S. EPA our Notice of Intent to Comply with the UAO and are currently cooperating with U.S. EPA as well as the Ohio EPA and Pennsylvania Department of Environmental Protection, pursuant to the UAO and the directives issued thereunder.

•The U.S. Department of Justice (DOJ) and the U.S. EPA filed a civil complaint (the DOJ Complaint) in the Northern District of Ohio (Eastern Division) seeking injunctive relief, cost recovery and civil penalties for violations of the Clean Water Act and seeking cost recovery under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA); and

In connection with the foregoing items, we recognized $317 million of expense during the first quarter, of which $31 million was paid, related to probable obligations that are reasonably estimable, in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 410-30, “Environmental Obligations.” Our current estimate includes ongoing and future environmental cleanup activities and remediation efforts, governmental oversight costs (including those incurred by the U.S. EPA and the Ohio EPA), and other related costs, including those in connection with the DOJ Complaint (including potential civil penalties related to violations of the Clean Water Act). Our current estimates of future environmental cleanup and remediation liabilities related to the Incident may change over time due to various factors, including but not limited to, the success of current cleanup techniques, the nature and extent of required future cleanup activities, and the extent of governmental oversight, amongst other factors. As clean-up efforts progress and more information is available, including any federal and state requirements, we will review these estimates and revise as appropriate.

action complaints currently allege numerous claims, including negligence, nuisance, trespass, and medical monitoring, and seek as relief, among other things, compensatory and punitive damages. The putative classes are currently defined by reference to class areas ranging from the evacuation zone up to 100 miles away. Additional multi-plaintiff lawsuits are also pending in the same court and others, such as additional lawsuits pending in the Western District of Pennsylvania brought by local school districts including claims such as negligence, nuisance, trespass, and future health monitoring. No responsive pleadings have yet been filed with respect to these matters (collectively referred to herein as the Incident Lawsuits). In accordance with ASC 450, “Contingencies,” we have recognized a $12 million probable loss in the first quarter with respect to the Incident Lawsuits, which is in addition to $16 million in amounts paid during the first quarter with respect to these matters.

•Securities litigation, including a securities class action lawsuit filed in the Southern District of Ohio alleging multiple securities law violations for which no responsive pleading has yet been filed, as well as multiple shareholder demand letters that we have received (collectively, the Shareholder Lawsuits).

If and when we conclude that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it will be accrued through a charge to earnings and, if material, disclosed. Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments become known. Because the final outcome of any of these legal proceedings cannot be predicted with certainty, unfavorable or unexpected developments or outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. For legal proceedings where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established but the matter, if potentially material, is disclosed.

The reserves established by us during the first quarter do not include any estimate of loss for the following items, for which we believe a loss is either not probable or not reasonably estimable for the reasons noted: (i) the overall cost to us for programs being developed in conjunction with the Ohio Attorney General for affected residents and businesses, which amounts will impact our loss contingency analysis with respect to the Incident Lawsuits described above, namely a healthcare fund, tailored protection for property owners, and programs to protect drinking water over the long term (given the preliminary nature of such discussions), or (ii) any fines or penalties (in excess of the reserves established for Clean Water Act-related civil penalties) that may be imposed as a result of the Incident Inquiries and Investigations, as more specifically set forth and defined below (the outcome of which are uncertain at this time). Additionally, as noted above, amounts recognized during the first quarter do not include potential recoveries from third parties, including the impact of our insurance coverage, which may apply to various Incident-related expenses or liabilities, as more specifically set forth further below (given the preliminary nature of any related discussions with our insurers).

As set forth above, we are subject to inquiries and investigations by numerous federal, state, and local government authorities and regulatory agencies regarding the Incident, including but not limited to, the DOJ and the U.S. EPA, the Ohio EPA, the National Transportation Safety Board (NTSB), the Federal Railroad Administration (FRA), the Occupational Safety and Health Administration, the Ohio Attorney General, and the Pennsylvania Attorney General. Further details regarding the NTSB and FRA investigations are set forth below. We are cooperating with all inquiries and investigations, including responding to civil and criminal subpoenas and other requests for information (the aforementioned inquiries and investigations, as well as the civil and criminal subpoenas are collectively referred to herein as the Incident Inquiries and Investigations). The outcome of any current or future Incident Inquiries and Investigations is uncertain at this time, including any related fines, penalties or settlements. Therefore, our first quarter expenses do not include estimates of the total amount that we may incur for any such fines, penalties or settlements.

Subsequent to the Incident, investigators from the NTSB examined railroad equipment and track conditions; reviewed data from the signal system, wayside defect detectors, local surveillance cameras, and the lead locomotive’s event recorder and forward-facing and inward-facing image recorders; and completed certain interviews (the NTSB Investigation). The NTSB issued a preliminary report indicating that one of the cars involved in the derailment appeared to have a wheel bearing in the final stage of overheat failure moments before the derailment. Their preliminary report also indicates that the rail crew was operating the train within our rules; the rail crew operated the train below the track speed limit, the wayside heat detectors were operating as designed; and once the rail crew was alerted by the wayside detector, they immediately began to stop the train. The NTSB’s investigation remains ongoing.

Concurrent with the NTSB Investigation, the FRA is also investigating the Incident. Similar in scope to the NTSB Investigation, the FRA is examining railroad equipment, track conditions, hazardous materials train placement and routing, and emergency response (the FRA Incident Investigation). The FRA Incident Investigation may result in the assessment of civil penalties. In addition to the FRA Incident Investigation, the FRA announced on March 7, 2023 that it would conduct a 60-day supplemental safety assessment (the FRA Safety Assessment). The FRA Safety Assessment will review findings from a previously completed 2022 system audit and assess operational elements including, but not limited to: track, signal, and rolling stock maintenance, inspection and repair practices; protection of employees; communications between transportation departments and mechanical and engineering staff; operation control center procedures and dispatcher training. The overall scope of the FRA Safety Assessment is to examine our safety culture. At the conclusion of the FRA Safety Assessment, the FRA will issue a public report which will include its findings and recommended corrective actions. The FRA Incident Investigation and the FRA Safety Assessment remain ongoing.

We and/or certain subsidiaries are defendants in numerous lawsuits and other claims relating principally to railroad operations. When we conclude that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to earnings and, if material, disclosed below. While the ultimate amount of liability incurred in any of these lawsuits and claims is dependent on future developments, in our opinion, the recorded liability is adequate to cover the future payment of such liability and claims. However, the final outcome of any of these lawsuits and claims cannot be predicted with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments become known. For lawsuits and other claims where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established but the matter, if potentially material, is disclosed below. We routinely review relevant information with respect to our lawsuits and other claims and update our accruals, disclosures and estimates of reasonably possible loss based on such reviews.

In 2007, various antitrust class actions filed against us and other Class I railroads in various Federal district courts regarding fuel surcharges were consolidated in the District of Columbia by the Judicial Panel on Multidistrict Litigation. In 2012, the court certified the case as a class action. The defendant railroads appealed this certification, and the Court of Appeals for the District of Columbia vacated the District Court’s decision and remanded the case for further consideration. On October 10, 2017, the District Court denied class certification. The decision was upheld by the Court of Appeals on August 16, 2019. Since that decision, various individual cases have been filed in multiple jurisdictions and also consolidated in the District of Columbia. We believe the allegations in the complaints are without merit and intend to vigorously defend the cases. We do not believe the outcome of these proceedings will have a material effect on our financial position, results of operations, or liquidity.

state laws and federal antitrust laws. On January 3, 2023, the court granted summary judgment to us on all of the compensatory claims but denied summary judgment for all equitable relief claims. On January 18, 2023, the court dismissed the federal equitable relief claims, leaving the state equitable relief claims as the sole remaining issue under consideration. On April 19, 2023, the court disposed of all remaining state equitable relief claims. These rulings may be appealed. If appealed, we will continue to vigorously defend the lawsuit and, although it is reasonably possible we could incur a loss in the case, we believe that we will prevail. However, given that litigation is inherently unpredictable and subject to uncertainties, there can be no assurances that the final outcome of the litigation (including any related appeal) will not be material. Until such appeal is final, we cannot reasonably estimate the potential loss or range of loss associated with this matter.

Casualty claims include employee personal injury and occupational claims as well as third-party claims, all exclusive of legal costs. To aid in valuing our personal injury liability and determining the amount to accrue with respect to such claims during the year, we utilize studies prepared by an independent consulting actuarial firm. Job-related personal injury and occupational claims are subject to the Federal Employer’s Liability Act (FELA), which is applicable only to railroads. The variability inherent in FELA’s fault-based tort system could result in actual costs being different from the liability recorded. While the ultimate amount of claims incurred is dependent on future developments, in our opinion, the recorded liability is adequate to cover the future payments of claims and is supported by the most recent actuarial study. In all cases, we record a liability when the expected loss for the claim is both probable and reasonably estimable.

Employee personal injury claims – Other than Incident-related matters noted above, the largest component of claims expense is employee personal injury costs. The independent actuarial firm we engage provides quarterly studies to aid in valuing our employee personal injury liability and estimating personal injury expense. The actuarial firm studies our historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences. The actuarial firm uses the results of these analyses to estimate the ultimate amount of liability. We adjust the liability quarterly based upon our assessment and the results of the study. The accuracy of our estimate of the liability is subject to inherent limitation given the difficulty of predicting future events such as jury decisions, court interpretations, or legislative changes. As a result, actual claim settlements may vary from the estimated liability recorded.

Occupational claims – Occupational claims include injuries and illnesses alleged to be caused by exposures which occur over time as opposed to injuries or illnesses caused by a specific accident or event. Types of occupational claims commonly seen allege exposure to asbestos and other claimed toxic substances resulting in respiratory diseases or cancer. Many such claims are being asserted by former or retired employees, some of whom have not been employed in the rail industry for decades. The independent actuarial firm provides an estimate of the occupational claims’ liability based upon our history of claim filings, severity, payments, and other pertinent facts. The liability is dependent upon judgments we make as to the specific case reserves as well as judgments of the actuarial firm in the quarterly studies. Our estimate of ultimate loss includes a provision for those claims that have been incurred but not reported. This provision is derived by analyzing industry data and projecting our experience. We adjust the liability quarterly based upon our assessment and the results of the study. However, it is possible that the recorded liability may not be adequate to cover the future payment of claims. Adjustments to the recorded liability are reflected in operating expenses in the periods in which such adjustments become known.

Third-party claims – We record a liability for third-party claims including those for highway crossing accidents, trespasser and other injuries, property damage, and lading damage. The actuarial firm assists us with the calculation of potential liability for third-party claims, except lading damage, based upon our experience including the number and timing of incidents, amount of payments, settlement rates, number of open claims, and legal defenses. We adjust the liability quarterly based upon our assessment and the results of the study. Given the inherent uncertainty in regard to the ultimate outcome of third-party claims, it is possible that the actual loss may differ from the estimated liability recorded.

We are subject to various jurisdictions’ environmental laws and regulations. We record a liability where such liability or loss is probable and reasonably estimable. Environmental specialists regularly participate in ongoing evaluations of all known sites and in determining any necessary adjustments to liability estimates.

In addition to environmental claims associated with the Incident, our Consolidated Balance Sheets include liabilities for other environmental exposures of $61 million at March 31, 2023 and $66 million at December 31, 2022, of which $15 million is classified as a current liability at the end of both periods. At March 31, 2023 and December 31, 2022, the liability represents our estimates of the probable cleanup, investigation, and remediation costs based on available information at 85 known locations and projects. At March 31, 2023, twenty sites accounted for $49 million of the liability, and no individual site was considered to be material. We anticipate that most of this liability will be paid out over five years; however, some costs will be paid out over a longer period.

At eight locations, one or more of our subsidiaries in conjunction with a number of other parties have been identified as potentially responsible parties under CERCLA or comparable state statutes that impose joint and several liability for cleanup costs. We calculate our estimated liability for these sites based on facts and legal defenses applicable to each site and not solely on the basis of the potential for joint liability.

As set forth above, with respect to known environmental sites (whether identified by us or by the U.S. EPA or comparable state authorities), estimates of our ultimate potential financial exposure for a given site or in the aggregate for all such sites can change over time because of the widely varying costs of currently available cleanup techniques, unpredictable contaminant recovery and reduction rates associated with available cleanup technologies, the likely development of new cleanup technologies, the difficulty of determining in advance the nature and full extent of contamination and each potential participant’s share of any estimated loss (and that participant’s ability to bear it), and evolving statutory and regulatory standards governing liability.

The risk of incurring environmental liability for acts and omissions, past, present, and future, is inherent in the railroad business. Some of the commodities we transport, particularly those classified as hazardous materials, pose special risks that we work diligently to reduce. In addition, several of our subsidiaries own, or have owned, land used as operating property, or which is leased and operated by others, or held for sale. Because environmental problems that are latent or undisclosed may exist on these properties, there can be no assurance that we will not incur environmental liabilities or costs with respect to one or more of them, the amount and materiality of which cannot be estimated reliably at this time. Moreover, lawsuits and claims involving these and potentially other unidentified environmental sites and matters are likely to arise from time to time. The resulting liabilities could have a significant effect on financial position, results of operations, or liquidity in a particular year or quarter.

Based on our assessment of the facts and circumstances now known, we believe we have recorded the probable and reasonably estimable costs for dealing with those environmental matters of which we are aware. Further, we believe that it is unlikely that any known matters, either individually or in the aggregate, will have a material adverse effect on our financial position, results of operations, or liquidity.

Approximately 80% of our railroad employees are covered by collective bargaining agreements with various labor unions. Pursuant to the Railway Labor Act, these agreements remain in effect until new agreements are reached, or until the bargaining procedures mandated by the Railway Labor Act are completed. Moratorium provisions in the labor agreements govern when the railroads and unions may propose changes to the agreements. We largely bargain nationally in concert with other major railroads, represented by the National Carriers’ Conference Committee.

discussions (none of which carry the risk of a work stoppage) with several of our unions to conclude the implementation of these national agreements. With the conclusion of national bargaining, neither party can compel mandatory bargaining around any new proposals until November 1, 2024.

We purchase insurance covering legal liabilities for bodily injury and property damage to third parties. This insurance provides coverage above $75 million and below $800 million (or up to $1.1 billion for specified types of pollution releases) per occurrence and/or policy year. In addition, we purchase insurance covering damage to property owned by us or in our care, custody, or control. This insurance covers approximately 82% of potential losses above $75 million and below $275 million per occurrence and/or policy year.

Our ability to recoup any of the foregoing amounts under our insurance coverage, including any amounts that may be recoverable with respect to the Incident, is subject to certain conditions, including but not limited to our insurers’ reservation of rights to further investigate and contest coverage, the express restrictions and sub-limits of coverage, and various policy exclusions, including those for some governmental fines or penalties, as well as potential coverage disputes over payments we make as part of our effort to mitigate the impact to the community and affected residents. We are working with our insurers to confirm applicable coverage with respect to the Incident, but no estimate for potential insurance recovery has been accrued at this time.
