operations.&#160;&#160;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 losses based on such reviews.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%">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&#8217;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.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%">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.

Although challenging winter conditions adversely impacted our network, we were able to reduce expenses while absorbing an increase in total volume.

first-quarter 2021 financial results reflect significant increases in income from railway operations, net income and diluted earnings per share, as prior year results were adversely impacted by a $385 million loss on asset disposal related to locomotives sold or designated as held-for-sale.  For more information on the impact of this charge, see Note 3.  Notwithstanding the prior year loss on asset disposal, railway operating expenses decreased as operational efficiency improvements resulted in reduced employment levels, lower materials costs, and improved fuel efficiency.  Additionally, fuel prices were lower compared to 2020.  Revenues were higher, a result of increased total volume that was partially offset by lower average revenue per unit as negative mix and lower fuel surcharge revenue more than offset pricing gains.  Our railway operating ratio improved to 61.5 percent, a quarterly record. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%">The following tables adjust our first-quarter 2020 GAAP financial results to exclude the loss on asset disposal.

Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;We recognize the amount of revenues to which we expect to be entitled for the transfer of promised goods or services to customers.  A performance obligation is created when a customer under a transportation contract or public tariff submits a bill of lading to us for the transport of goods.  These performance obligations are satisfied as the shipments move from origin to destination.  As such, transportation revenues are recognized proportionally as a shipment moves, and related expenses are recognized as incurred.  These performance obligations are generally short-term in nature with transit days averaging approximately one week or less for each commodity group.  The customer has an unconditional obligation to pay for the service once the service has been completed.  Estimated revenues associated with in-process shipments at period-end are recorded based on the estimated percentage of service completed.  We had no material remaining performance obligations at March&#160;31, 2021 and December&#160;31, 2020.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;We may provide customers ancillary services, such as switching, demurrage and other incidental activities, under their transportation contracts.  These are distinct performance obligations that are recognized at a point in time when the services are performed or as contractual obligations are met.  These revenues are included within each of the commodity groups and represent approximately 6% and 5% of total &#x201c;Railway operating revenues&#x201d; on the Consolidated Statements of Income for the first quarters ended March 31, 2021 and March 31, 2020, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Revenues related to interline transportation services that involve another railroad are reported on a net basis. Therefore, the portion of the amount that relates to another party is not reflected in revenues.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Under the typical terms of our freight contracts, payment for services is due within fifteen days of billing the customer, thus there are no significant financing components.  &#x201c;Accounts receivable &#x2013; net&#x201d; on the Consolidated Balance Sheets includes both customer and non-customer receivables as

the first quarters of 2021 and 2020, dividend equivalent payments were made to holders of stock options and RSUs.&#160;&#160;For purposes of computing basic earnings per share, dividend equivalent payments made to holders of stock options and RSUs were deducted from net income to determine income available to common stockholders.  For purposes of computing diluted earnings per share, we evaluate on a grant-by-grant basis those stock options and RSUs receiving dividend equivalent payments under the two-class and treasury stock methods to determine which method is more dilutive for each grant.  For those grants for which the two-class method was more dilutive, net income was reduced by dividend equivalent payments to determine income available to common stockholders.  There are no options excluded from the dilution calculations due to exercise prices exceeding the average market price of Common Stock for the first quarters ended March&#160;31, 2021 and 2020.</us-gaap:EarningsPerShareTextBlock>

We also provide specified health care benefits to eligible retired employees; these plans can be amended or terminated at our option.&#160; Under our self-insured retiree health care plan, for those participants who are not Medicare-eligible, certain health care expenses are covered for retired employees and their dependents, reduced by any deductibles, coinsurance, and, in some cases, coverage provided under other group insurance policies.&#160; Eligible retired participants and their spouses who are Medicare-eligible are not covered under the self-insured retiree health care plan, but instead are provided with an employer-funded health reimbursement account which can be used for reimbursement of health insurance premiums or eligible out-of-pocket medical expenses.

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 losses based on such reviews.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%"&gt;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&#x2019;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.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%"&gt;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. It is reasonably possible that we could incur a loss in the case; however, we intend to vigorously defend the case and believe that we will prevail.  The potential range of loss cannot be estimated at this time.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;Casualty Claims &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Casualty claims include employee personal injury and occupational claims as well as third-party claims, all exclusive of legal costs.&#160;&#160;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.&#160;&#160;Job-&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;related personal injury and occupational claims are subject to the Federal Employer&#x2019;s Liability Act (FELA), which is applicable only to railroads.&#160;&#160;FELA&#x2019;s fault-based tort system produces results that are unpredictable and inconsistent as compared with a no-fault workers&#x2019; compensation system.&#160;&#160;The variability inherent in this system could result in actual costs being different from the liability recorded.&#160;&#160;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.&#160;&#160;In all cases, we record a liability when the expected loss for the claim is both probable and reasonably estimable.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;Employee personal injury claims &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2013; The largest component of claims expense is employee personal injury costs.&#160;&#160;The independent actuarial firm we engage provides quarterly studies to aid in valuing our employee personal injury liability and estimating personal injury expense.&#160;&#160;The actuarial firm studies our historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences.&#160;&#160;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.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;Occupational claims&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt; &#x2013; 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.&#160;&#160;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.&#160;&#160;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.&#160;&#160;The actuarial firm&#x2019;s estimate of ultimate loss includes a provision for those claims that have been incurred but not reported.&#160;&#160;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.&#160;&#160;However, it is possible that the recorded liability may not be adequate to cover the future payment of claims.&#160;&#160;Adjustments to the recorded liability are reflected in operating expenses in the periods in which such adjustments become known.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;Third-party claims&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt; &#x2013; We record a liability for third-party claims including those for highway crossing accidents, trespasser and other injuries, property damage, and lading damage.&#160;&#160;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.&#160;&#160;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.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;Environmental Matters&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;We are subject to various jurisdictions&#x2019; environmental laws and regulations.&#160;&#160;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.&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Our Consolidated Balance Sheets include liabilities for environmental exposures of $51 million at March&#160;31, 2021, and $54 million at December&#160;31, 2020, of which $15 million is classified as a current liability at the end of both periods.  At both March&#160;31, 2021 and December&#160;31, 2020, the liability represents our estimates of the probable cleanup, investigation, and remediation costs based on available information at 100 known locations and projects.  At March&#160;31, 2021, seventeen sites accounted for $38 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.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;At eleven locations, one or more of our subsidiaries in conjunction with a number of other parties have been identified as potentially responsible parties under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 or comparable state statutes that impose joint and several liability for cleanup costs.&#160;&#160;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.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;With respect to known environmental sites (whether identified by us or by the Environmental Protection Agency 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&#x2019;s share of any estimated loss (and that participant&#x2019;s ability to bear it), and evolving statutory and regulatory standards governing liability.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The risk of incurring environmental liability for acts and omissions, past, present, and future, is inherent in the railroad business.&#160;&#160;Some of the commodities we transport, particularly those classified as hazardous materials, pose special risks that we work diligently to reduce.&#160;&#160;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.&#160;&#160;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.&#160;&#160;Moreover, lawsuits and claims involving these and potentially other unidentified environmental sites and matters are likely to arise from time to time.&#160;&#160;The resulting liabilities could have a significant effect on financial position, results of operations, or liquidity in a particular year or quarter.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Based on our assessment of the facts and circumstances now known, we believe we have recorded the probable and reasonably estimable costs for those environmental matters of which we are aware.&#160; 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.  &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;Insurance&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%"&gt;We purchase insurance covering legal liabilities for bodily injury and property damage to third parties.

A performance obligation is created when a customer under a transportation contract or public tariff submits a bill of lading to us for the transport of goods.  These performance obligations are satisfied as the shipments move from origin to destination.  As such, transportation revenues are recognized proportionally as a shipment moves, and related expenses are recognized as incurred.  These performance obligations are generally short-term in nature with transit days averaging approximately one week or less for each commodity group.  The customer has an unconditional obligation to pay for the service once the service has been completed.  Estimated revenues associated with in-process shipments at period-end are recorded based on the estimated percentage of service completed.

These are distinct performance obligations that are recognized at a point in time when the services are performed or as contractual obligations are met.

the first quarters of 2021 and 2020, dividend equivalent payments were made to holders of stock options and RSUs.&#160;&#160;For purposes of computing basic earnings per share, dividend equivalent payments made to holders of stock options and RSUs were deducted from net income to determine income available to common stockholders.  For purposes of computing diluted earnings per share, we evaluate on a grant-by-grant basis those stock options and RSUs receiving dividend equivalent payments under the two-class and treasury stock methods to determine which method is more dilutive for each grant.  For those grants for which the two-class method was more dilutive, net income was reduced by dividend equivalent payments to determine income available to common stockholders.  There are no options excluded from the dilution calculations due to exercise prices exceeding the average market price of Common Stock for the first quarters ended March&#160;31, 2021 and 2020.<span></span>

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 losses based on such reviews.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%">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&#8217;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.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:115%">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. It is reasonably possible that we could incur a loss in the case; however, we intend to vigorously defend the case and believe that we will prevail.  The potential range of loss cannot be estimated at this time.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%">Casualty Claims </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Casualty claims include employee personal injury and occupational claims as well as third-party claims, all exclusive of legal costs.&#160;&#160;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.&#160;&#160;Job-</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">related personal injury and occupational claims are subject to the Federal Employer&#8217;s Liability Act (FELA), which is applicable only to railroads.&#160;&#160;FELA&#8217;s fault-based tort system produces results that are unpredictable and inconsistent as compared with a no-fault workers&#8217; compensation system.&#160;&#160;The variability inherent in this system could result in actual costs being different from the liability recorded.&#160;&#160;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.&#160;&#160;In all cases, we record a liability when the expected loss for the claim is both probable and reasonably estimable.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%">Employee personal injury claims </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#8211; The largest component of claims expense is employee personal injury costs.&#160;&#160;The independent actuarial firm we engage provides quarterly studies to aid in valuing our employee personal injury liability and estimating personal injury expense.&#160;&#160;The actuarial firm studies our historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences.&#160;&#160;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.  </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%">Occupational claims</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"> &#8211; 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.&#160;&#160;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.&#160;&#160;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.&#160;&#160;The actuarial firm&#8217;s estimate of ultimate loss includes a provision for those claims that have been incurred but not reported.&#160;&#160;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.&#160;&#160;However, it is possible that the recorded liability may not be adequate to cover the future payment of claims.&#160;&#160;Adjustments to the recorded liability are reflected in operating expenses in the periods in which such adjustments become known.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%">Third-party claims</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"> &#8211; We record a liability for third-party claims including those for highway crossing accidents, trespasser and other injuries, property damage, and lading damage.&#160;&#160;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.&#160;&#160;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.  </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%">Environmental Matters</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#160;</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">We are subject to various jurisdictions&#8217; environmental laws and regulations.&#160;&#160;We record a liability where such liability or loss is probable and reasonably estimable.

At both March&#160;31, 2021 and December&#160;31, 2020, the liability represents our estimates of the probable cleanup, investigation, and remediation costs based on available information at 100 known locations and projects.  At March&#160;31, 2021, seventeen sites accounted for $38 million of the liability, and no individual site was considered to be material.
