Should a number of these items occur in the same period, however, their combined effect could be material in that particular period.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:700;line-height:120%">Casualty </span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#160;&#160;&#160;&#160; Casualty reserves of $<ix:nonFraction unitRef="usd" contextRef="ie10a9373fa2344b5a48e31c61819871d_I20210331" decimals="-6" format="ixt:numdotdecimal" name="us-gaap:LossContingencyAccrualAtCarryingValue" scale="6" id="id3VybDovL2RvY3MudjEvZG9jOjVlZjFlMTE1NTQxNzQyODNhNWJiOTMyYWM4ZTcwZjA1L3NlYzo1ZWYxZTExNTU0MTc0MjgzYTViYjkzMmFjOGU3MGYwNV80MC9mcmFnOmY4ZWJjMTRhMGM5ZDQ5NDZhYTM1NDMwYTRkZWNmYzlhL3RleHRyZWdpb246ZjhlYmMxNGEwYzlkNDk0NmFhMzU0MzBhNGRlY2ZjOWFfMTA0OA_b8c41fa8-0277-4dc8-af56-027b9152442f">200</ix:nonFraction> million and $<ix:nonFraction unitRef="usd" contextRef="idc320513629041dbb4a08ead8ce5fce2_I20201231" decimals="-6" format="ixt:numdotdecimal" name="us-gaap:LossContingencyAccrualAtCarryingValue" scale="6" id="id3VybDovL2RvY3MudjEvZG9jOjVlZjFlMTE1NTQxNzQyODNhNWJiOTMyYWM4ZTcwZjA1L3NlYzo1ZWYxZTExNTU0MTc0MjgzYTViYjkzMmFjOGU3MGYwNV80MC9mcmFnOmY4ZWJjMTRhMGM5ZDQ5NDZhYTM1NDMwYTRkZWNmYzlhL3RleHRyZWdpb246ZjhlYmMxNGEwYzlkNDk0NmFhMzU0MzBhNGRlY2ZjOWFfMTA1NQ_eec91f85-48e6-44b4-8d78-014fb8f46bbf">196</ix:nonFraction> million as of March&#160;31, 2021 and December&#160;31, 2020, respectively, represent accruals for personal injury, occupational disease and occupational injury claims. </span><span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">The Company's self-insured retention amount for these claims is $<ix:nonFraction unitRef="usd" contextRef="i7a4437ca9c084f41bde3cc43fed39c70_D20210101-20210331" decimals="INF" format="ixt:numdotdecimal" name="csx:SelfInsuredRetention" scale="6" id="id3VybDovL2RvY3MudjEvZG9jOjVlZjFlMTE1NTQxNzQyODNhNWJiOTMyYWM4ZTcwZjA1L3NlYzo1ZWYxZTExNTU0MTc0MjgzYTViYjkzMmFjOGU3MGYwNV80MC9mcmFnOmY4ZWJjMTRhMGM5ZDQ5NDZhYTM1NDMwYTRkZWNmYzlhL3RleHRyZWdpb246ZjhlYmMxNGEwYzlkNDk0NmFhMzU0MzBhNGRlY2ZjOWFfMTI0Ng_c0883278-6059-4133-bcfe-c1e92e4bde0d">75</ix:nonFraction> million per occurrence.

The Company&#8217;s performance obligation arises when it receives a bill of lading (&#8220;BOL&#8221;) 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. </ix:nonNumeric></span></div></ix:continuation><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="height:45pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">CSX Q1 2021 Form 10-Q p.20</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:72pt;width:100%"><div><span style="color:#0000ff;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i5ef1e11554174283a5bb932ac8e70f05_7">Table of Contents</a></span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">       </span></div><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">CSX CORPORATION</span></div><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">NOTES TO CONSOLIDATED FINANCIAL STATEMENTS</span></div><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">(Unaudited)</span></div></div><ix:continuation id="i6206b46cf2264c99a6bbeeb947cf9069" continuedAt="i3d72f8d492da4c6e8bf74e4d06f1701c"><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">NOTE 8. &#160;&#160;&#160;&#160;Revenues, </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">continued</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><ix:continuation id="ia68879d862aa4de1a9253e5b254cde35" continuedAt="i415fcf22366546acb00fce511d1b879a"><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">The average transit time to complete a shipment is between <ix:nonNumeric contextRef="i75620ba90ede45cda0b907d81cc47c66_D20210101-20210331" format="ixt-sec:durday" name="csx:RevenuePerformanceObligationAverageTransitTime" id="id3VybDovL2RvY3MudjEvZG9jOjVlZjFlMTE1NTQxNzQyODNhNWJiOTMyYWM4ZTcwZjA1L3NlYzo1ZWYxZTExNTU0MTc0MjgzYTViYjkzMmFjOGU3MGYwNV81Mi9mcmFnOjFlZmVjYTFmNmUxODQ1NTc5MjI0Y2ZkMzhmZmZkMTA5L3RleHRyZWdpb246MWVmZWNhMWY2ZTE4NDU1NzkyMjRjZmQzOGZmZmQxMDlfMTY2Nw_761b89d9-1842-4aef-a00f-8e1e653da339">2</ix:nonNumeric> to <ix:nonNumeric contextRef="ieddb076107a14505a79cf922d0765d2a_D20210101-20210331" format="ixt-sec:durday" name="csx:RevenuePerformanceObligationAverageTransitTime" id="id3VybDovL2RvY3MudjEvZG9jOjVlZjFlMTE1NTQxNzQyODNhNWJiOTMyYWM4ZTcwZjA1L3NlYzo1ZWYxZTExNTU0MTc0MjgzYTViYjkzMmFjOGU3MGYwNV81Mi9mcmFnOjFlZmVjYTFmNmUxODQ1NTc5MjI0Y2ZkMzhmZmZkMTA5L3RleHRyZWdpb246MWVmZWNhMWY2ZTE4NDU1NzkyMjRjZmQzOGZmZmQxMDlfMTY3Mw_f11c4599-e323-4bcb-9415-e5ebed17692b">8</ix:nonNumeric> days depending on market.

Company's only financial instrument with fair values significantly different from their carrying amounts. The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.</span></div></ix:continuation><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"><ix:continuation id="i53c8b2b6c8ed49c09154d1ca882ae53b" continuedAt="i198a6f4598054272af68d8306f5ffcf1">The fair value of outstanding debt fluctuates with changes in a number of factors. Such factors include, but are not limited to, interest rates, market conditions, credit ratings, values of similar financial instruments, size of the transaction, cash flow projections and comparable trades. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules.</ix:continuation> <ix:nonNumeric contextRef="i706c9a6cf6214a90bd901b26693a31d2_D20210101-20210331"

declines in the first half of 2020, but the effects of the disruption of global manufacturing, supply chains and consumer spending as a result of the COVID-19 global pandemic are ongoing. As this continues to be a dynamic situation, it is difficult to determine the lasting impacts of the pandemic, including the extent of its impact on the Company&#8217;s financial and operating results. The full implications of COVID-19 will be determined by the length of time that the pandemic continues, its effect on the demand for the Company&#8217;s transportation services and the supply chain, as well as the effect of governmental regulations imposed and legislative stimulus packages passed in response to the pandemic. The duration of the pandemic is dependent on several factors, including the timing of vaccine production and distribution as well as the impacts of virus mutations and case resurgences across the country.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:115%">CSX employees that provide efficient and reliable rail service are essential to keeping supply chains fluid in response to this challenge. Accordingly, business operations have been modified to ensure the safety of employees across the network while continuing to provide a high level of service to customers. A cross-functional task force monitors and coordinates the Company&#8217;s response to COVID-19. Policies and procedures established to protect the health and safety of employees and customers and to safeguard CSX operations include rigorous cleaning regimens for equipment and facilities, provision of sanitation supplies, distribution of disposable face coverings, facilitation of social distancing measures and administration of temperature testing at certain facilities. These precautions remain in place despite the easing of pandemic restrictions by state and local governments across the network. </span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">CSX Q1 2021 Form 10-Q p.26</span></div></div></div><div id="i5ef1e11554174283a5bb932ac8e70f05_85"></div><hr style="page-break-after:always"/><div style="min-height:72pt;width:100%"><div><span style="color:#0000ff;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#i5ef1e11554174283a5bb932ac8e70f05_7">Table of Contents </a></span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">                           </span></div><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">CSX CORPORATION</span></div><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">ITEM 2.

Free cash flow is calculated by using net cash from operations and adjusting for property additions and certain other investing activities, which includes proceeds from property dispositions. Free cash flow should be considered in addition to, rather than a substitute for, cash provided by operating activities.&#160;The increase in free cash flow before dividends from the prior year of

CSX Corporation has fully and unconditionally guaranteed the notes. At CSXT&#8217;s option, CSXT may redeem any or all of the notes, in whole or in part, at any time, at the redemption price including premium. In the case of loss or destruction of any item of equipment securing the notes, if CSXT does not substitute another item of equipment for the item suffering such loss or destruction, CSXT will be required to redeem the notes in part at par. The guarantee of the notes will rank equally in right of payment with all existing and future senior obligations of CSX Corporation and will be effectively subordinated to all future secured indebtedness of CSX Corporation to the extent of the assets securing such indebtedness. The guarantee is subject to release in limited circumstances only upon the occurrence of certain customary conditions.

Earnings per share, assuming dilution, is based on the weighted-average number of shares of common stock outstanding and common stock equivalents adjusted for the effects of common stock that may be issued as a result of potentially dilutive instruments.

This number is different from outstanding stock options because it is offset by shares CSX could repurchase using the proceeds from these hypothetical exercises to obtain the common stock equivalent. The total average outstanding stock options that were excluded from the diluted earnings per share calculation because their effect was antidilutive is in the table below. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:6pt;text-align:justify"&gt;&lt;table style="border-collapse:collapse;display:inline-table;vertical-align:top;width:100.000%"&gt;&lt;tr&gt;&lt;td style="width:1.0%"/&gt;&lt;td style="width:70.829%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td style="width:1.0%"/&gt;&lt;td style="width:12.935%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td style="width:1.0%"/&gt;&lt;td style="width:12.936%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td colspan="3" style="padding:0 1pt"/&gt;&lt;td colspan="6" style="padding:2px 1pt;text-align:center;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:100%"&gt;First Quarters&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td colspan="3" style="padding:0 1pt"/&gt;&lt;td colspan="3" style="border-top:1pt solid #000000;padding:2px 1pt;text-align:center;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:100%"&gt;2021&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="border-top:1pt solid #000000;padding:2px 1pt;text-align:center;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:100%"&gt;2020&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:bottom"&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:100%"&gt;Antidilutive Stock Options Excluded from Diluted EPS &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:100%"&gt;(Millions)&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td colspan="3" style="border-top:1pt solid #000000;padding:2px 1pt;text-align:right;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:100%"&gt;1&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="border-top:1pt solid #000000;padding:2px 1pt;text-align:right;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:100%"&gt;1&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;td colspan="3" style="display:none"/&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:700;line-height:120%"&gt;Share Repurchases&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:115%"&gt; &#160;&#160;&#160;&#160;In January 2019, the Company announced a $5&#160;billion share repurchase program.

Awards granted under the various programs are determined and approved by the Compensation and Talent Management Committee of the Board of Directors. Awards to the Chief Executive Officer are approved by the full Board and awards to senior executives are approved by the Compensation and Talent Management Committee. In certain circumstances, the Chief Executive Officer or delegate approves awards to management employees other than senior executives. The Board of Directors approves awards granted to CSX's non-management directors upon recommendation of the Governance and Sustainability Committee. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;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 or upon grant date to certain retirement-eligible employees whose agreements allow for continued vesting upon retirement. Forfeitures are recognized as they occur. Total pre-tax expense and income tax benefits associated with share-based compensation are shown in the table below. Income tax benefits include impacts from option exercises and the vesting of other equity awards. &lt;/span&gt;&lt;/div&gt;&lt;div

The payout range for participants will be between 0% and 200% of the target awards depending on Company performance against predetermined goals. 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. Participants will receive stock dividend equivalents declared over the performance period based on the number of performance units paid upon vesting. The fair values of the performance units awarded during the quarters ended March 31, 2021 and March 31, 2020 were primarily calculated using a Monte-Carlo simulation model with the following

granted approximately 610 thousand stock options along with the corresponding LTIP. The fair value of stock options was calculated using the Black-Scholes valuation model. These stock options were granted with ten-year terms and vest over three years in equal installments each year on the anniversary of the grant date. The exercise price for stock options granted equals the closing market price of the underlying stock on the date of grant. These awards are time-based and are not based upon attainment of performance goals. During first quarters 2021 and 2020, there were additional immaterial grants of stock options to certain members of management. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span

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.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:700;line-height:120%"&gt;Casualty &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160; Casualty reserves of $200 million and $196 million as of March&#160;31, 2021 and December&#160;31, 2020, respectively, represent accruals for personal injury, occupational disease and occupational injury claims. &lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The Company's self-insured retention amount for these claims is $75 million per occurrence. Currently, no individual claim is expected to exceed the self-insured retention amount. &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;In accordance with the &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;Contingencies Topic&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt; 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. 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.&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:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;Personal Injury&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;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&#x2019; Liability Act (&#x201c;FELA&#x201d;). CSXT retains an independent actuary to assist management in assessing the value of personal &lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;injury claims. An analysis is performed by the actuary quarterly and is reviewed by management. This analysis did not result in a material adjustment to the personal injury reserve in the quarter ended March&#160;31, 2021 or March&#160;31, 2020. The&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt; methodology used by the actuary includes a development factor to reflect growth or reduction in the value of these personal injury claims based largely on CSXT's historical claims and settlement experience.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;NOTE 4.&#160;&#160;&#160;&#160;Casualty, Environmental and Other Reserves, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;continued&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;Occupational&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:115%"&gt;&#160;&#160;&#160;&#160;Occupational reserves represent liabilities arising from allegations of exposure to certain materials in the workplace (such as solvents, soaps, chemicals and diesel fumes), past exposure to asbestos or allegations of chronic physical injuries resulting from work conditions (such as repetitive stress injuries). Beginning in second quarter 2020, the Company retains an independent actuary to analyze the Company&#x2019;s historical claim filings, settlement amounts, and dismissal rates to assist in determining future anticipated claim filing rates and average settlement values.

There were no material adjustments to the occupational reserve in the quarter ended March&#160;31, 2021 or March&#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:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:700;line-height:115%"&gt;Environmental&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Environmental reserves were $77 million and $76 million as of March&#160;31, 2021 and December&#160;31, 2020, respectively. The Company is a party to various proceedings related to environmental issues, including administrative and judicial proceedings involving private parties and regulatory agencies. The Company has been identified as a potentially responsible party at approximately 220 environmentally impaired sites. &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;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. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;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.

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, supplies and other on the consolidated income statements.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;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. &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:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:700;line-height:120%"&gt;Other &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Other reserves were $41 million and $42 million as of March&#160;31, 2021 and December&#160;31, 2020, respectively.

A certain amount of risk is retained by the Company on each insurance program. Under its property insurance program, the Company retains all risk up to $100 million per occurrence for losses from floods and named windstorms and $75 million per occurrence for other property losses.&#160;For third-party liability claims, the Company retains all risk up to $75 million per occurrence. As CSX negotiates insurance coverage above its full self-retention amounts, it retains a percentage of risk at various layers of coverage. While the Company believes its insurance coverage is adequate, future claims could exceed existing insurance coverage or insurance may not continue to be available at commercially reasonable rates.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;NOTE 5.&#160;&#160;&#160;&#160;Commitments and Contingencies, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;continued&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:700;line-height:120%"&gt;Legal&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt; &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;The Company is involved in litigation incidental to its business and is a party to a number of legal actions and claims, various governmental proceedings and private civil lawsuits, including, but not limited to, those related to fuel surcharge practices, tax matters, environmental and hazardous material exposure matters, FELA and labor claims by current or former employees, other personal injury or property claims and disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for compensatory as well as punitive damages and others are, or are purported to be, class actions. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the legal defenses available and liabilities that have been recorded along with applicable insurance, it is currently the opinion of management that none of these pending items is likely to have a material adverse effect on the Company's financial condition, results of operations or liquidity.  An unexpected adverse resolution of one or more of these items, however, could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;The Company is able to estimate a range of possible loss for certain legal proceedings for which a loss is reasonably possible in excess of reserves established. The Company has estimated this range to be $1 million to $20 million in aggregate at March&#160;31, 2021. This estimated aggregate range is based upon currently available information and is subject to significant judgment and a variety of assumptions. Accordingly, the Company's estimate will change from time to time, and actual losses may vary significantly from the current estimate.&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:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;Fuel Surcharge Antitrust Litigation&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;In May 2007, class action lawsuits were filed against CSXT and three other U.S.-based Class I railroads alleging that the defendants' fuel surcharge practices relating to contract and unregulated traffic resulted from an illegal conspiracy in violation of antitrust laws. The class action lawsuits were consolidated into one case in federal court in the District of Columbia. In 2017, the District Court issued its decision denying class certification. On August 16, 2019, the U.S. Court of Appeals for the D.C. Circuit affirmed the District Court&#x2019;s ruling.  &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:115%"&gt;&#160;&#160;&#160;&#160;The consolidated case is now moving forward without class certification. Although a class was not certified, shippers other than those who brought the original lawsuit in 2007 must decide whether to bring their own individual claim against one or more railroads. Individual shipper claims filed to date have been consolidated into a separate case.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;CSXT believes that its fuel surcharge practices were arrived at and applied lawfully and that the case is without merit. Accordingly, the Company intends to defend itself vigorously. However, penalties for violating antitrust laws can be severe, and resolution of these matters individually or when aggregated could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;NOTE 5.&#160;&#160;&#160;&#160;Commitments and Contingencies, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;continued&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:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;Environmental&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;CSXT is indemnifying Pharmacia LLC, formerly known as Monsanto Company, ("Pharmacia") for certain liabilities associated with real estate located in Kearny, New Jersey along the Lower Passaic River (the &#x201c;Property&#x201d;). The Property, which was formerly owned by Pharmacia, is now owned by CSXT. CSXT's indemnification and defense duties arise with respect to several matters. The U.S. Environmental Protection Agency ("EPA"), using its CERCLA authority, seeks the investigation and cleanup of hazardous substances in the 17-mile Lower Passaic River Study Area (the "Study Area&#x201d;). CSXT, on behalf of Pharmacia, and a significant number of other potentially responsible parties are together conducting a Remedial Investigation and Feasibility Study of the Study Area pursuant to an Administrative Settlement Agreement and Order on Consent with the EPA. Pharmacia&#x2019;s share of responsibility, indemnified by CSXT, for the investigation and cleanup costs of the Study Area may be determined through various mechanisms including (a) an allocation and settlement with EPA; (b) litigation brought by EPA against non-settling parties; or (c) litigation among the responsible parties. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;            In March 2016, EPA issued its Record of Decision detailing the agency&#x2019;s mandated remedial process for the lower 8 miles of the Study Area. Approximately 80 parties, including Pharmacia, are participating in an EPA-directed allocation and settlement process to assign responsibility for the remedy selected for the lower 8 miles of the Study Area. CSXT is participating in the EPA-directed allocation and settlement process on behalf of Pharmacia. At a later date, EPA will select a remedy for the remainder of the Study Area and is expected to again seek the participation of private parties to implement the selected remedy using EPA&#x2019;s CERCLA authority to compel such participation, if necessary.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;            CSXT is also defending and indemnifying Pharmacia with regard to the Property in litigation filed by Occidental Chemical Corporation ("Occidental"), which is seeking to recover various costs. These costs include costs for the remedial design of the lower 8 miles of the Study Area, as well as anticipated costs associated with the future remediation of the lower 8 miles of the Study Area and potentially the entire Study Area. Alternatively, Occidental seeks to compel some, or all of the defendants to participate in the remediation of the Study Area. Pharmacia is one of approximately 110 defendants in this federal lawsuit filed by Occidental on June 30, 2018.&lt;/span&gt;&lt;/div&gt;            CSXT is also defending and indemnifying Pharmacia in a cooperative natural resource damages assessment process related to the Property. Based on currently available information, the Company does not believe any indemnification or remediation costs potentially allocable to CSXT with respect to the Property and the Study Area would be material to the Company's financial condition, results of operations or liquidity.</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

2020, the Company executed a forward starting interest rate swap with a notional value of $250&#160;million for an aggregate notional value of $500&#160;million. These swaps were effected to hedge the benchmark interest rate associated with future interest payments related to the anticipated refinancing of $850&#160;million of 3.25% notes due in 2027.

This facility allows same-day borrowings at floating interest rates, based on LIBOR or an agreed-upon replacement, plus a spread that depends upon&#160;CSX's senior unsecured debt ratings. LIBOR is the London Interbank Offered Rate which is a daily reference rate based on the interest rates at which banks offer to lend unsecured funds. This facility expires in March 2024, and at March 31, 2021, the Company had no outstanding balances under this facility. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;Commitment fees and interest rates payable under the facility were similar to fees and rates available to comparably rated investment-grade borrowers. As of first quarter 2021, CSX was in compliance with all covenant requirements under this facility. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:700;line-height:120%"&gt;Commercial Paper&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;Under its commercial paper program, which is backed by the revolving credit facility, the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount of $1.0 billion outstanding at any one time. Proceeds from issuances of the notes are expected to be used for general corporate purposes. At March 31, 2021, the Company had no outstanding debt under the commercial paper program.&lt;/span&gt;&lt;/div&gt;</us-gaap:DebtDisclosureTextBlock>

The Company&#x2019;s performance obligation arises when it receives a bill of lading (&#x201c;BOL&#x201d;) 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. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt;NOTE 8. &#160;&#160;&#160;&#160;Revenues, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;continued&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The average transit time to complete a shipment is between 2 to 8 days depending on market. Payments for transportation services are normally billed once a BOL is received and are generally due within 15 days after the invoice date. The Company recognizes revenue over transit time of freight as it moves from origin to destination. Revenue for services started but not completed at the reporting date is allocated based on the relative transit time in each reporting period, with the portion allocated for services subsequent to the reporting date considered remaining performance obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The certain key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;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;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;Adjustments to revenue for billing corrections and billing discounts;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;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&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;Incentive-based refunds to customers, which are primarily volume-related, are recorded as a reduction to revenue on the basis of the projected liability&#160;(this estimate is based on historical activity, current volume levels and forecasted future volume).&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Revenue related to interline transportation services that involve the services of another party, such as another railroad, is reported on a net basis.

It is recorded upon completion of the service and accounts for an immaterial percentage of the Company's total revenue. 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.

The Company&#x2019;s performance obligation arises when it receives a bill of lading (&#x201c;BOL&#x201d;) 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. &lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The average transit time to complete a shipment is between 2 to 8 days depending on market. Payments for transportation services are normally billed once a BOL is received and are generally due within 15 days after the invoice date. The Company recognizes revenue over transit time of freight as it moves from origin to destination. Revenue for services started but not completed at the reporting date is allocated based on the relative transit time in each reporting period, with the portion allocated for services subsequent to the reporting date considered remaining performance obligations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The certain key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;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;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;Adjustments to revenue for billing corrections and billing discounts;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;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&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:45pt;text-align:justify;text-indent:-9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt"&gt;Incentive-based refunds to customers, which are primarily volume-related, are recorded as a reduction to revenue on the basis of the projected liability&#160;(this estimate is based on historical activity, current volume levels and forecasted future volume).&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Revenue related to interline transportation services that involve the services of another party, such as another railroad, is reported on a net basis.

It is recorded upon completion of the service and accounts for an immaterial percentage of the Company's total revenue. 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. Switching represents charges assessed when a railroad switches cars for a customer or another railroad. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;During the first quarters 2021 and 2020, revenue recognized from performance obligations related to prior periods (for example, due to changes in transaction price) was not material.&lt;/span&gt;&lt;/div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Remaining performance obligations represent the transaction price allocated to future reporting periods for freight services started but not completed at the reporting date&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;.&lt;/span&gt; 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 timing of revenue recognition, billings and cash collections results in accounts receivable and customer advances and deposits (contract liabilities) on the consolidated balance sheets. &lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Freight receivables include amounts earned, billed and unbilled&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;,&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt; and currently due from customers&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; &lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;for transportation-related services. Non-freight receivables include amounts billed and unbilled and currently due related to government reimbursement receivables and other non-revenue receivables. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of risk characteristics, historical payment experience, and the age of outstanding receivables adjusted for forward-looking economic conditions as necessary.&lt;/span&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Long-term debt is reported at carrying amount on the consolidated balance sheets and is the Company's only financial instrument with fair values significantly different from their carrying amounts. The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The fair value of outstanding debt fluctuates with changes in a number of factors. Such factors include, but are not limited to, interest rates, market conditions, credit ratings, values of similar financial instruments, size of the transaction, cash flow projections and comparable trades. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules. The fair value and carrying value of the Company's long-term debt is as follows: &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:6pt;text-align:center"&gt;&lt;table

The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.&lt;/span&gt;&lt;/div&gt;The fair value of outstanding debt fluctuates with changes in a number of factors. Such factors include, but are not limited to, interest rates, market conditions, credit ratings, values of similar financial instruments, size of the transaction, cash flow projections and comparable trades. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules.Interest Rate DerivativesThe Company&#x2019;s forward starting interest rate swaps are carried at fair value and valued with assistance from a third party based upon pricing models using inputs observed from actively quoted markets. All of the inputs used to determine the fair value of the swaps are Level 2 inputs.</us-gaap:FairValueMeasurementPolicyPolicyTextBlock>

Total comprehensive earnings are defined as all changes in shareholders' equity during a period, other than those resulting from investments by and distributions to shareholders (e.g. issuance of equity securities and dividends). Generally, for CSX, total comprehensive earnings equal net earnings plus or minus adjustments for pension and other post-retirement liabilities as well as other adjustments. Total comprehensive earnings represent the activity for a period net of tax and were $774 million and $773 million for first quarters 2021 and 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 style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;While total comprehensive earnings is the activity in a period and is largely driven by net earnings in that period, accumulated other comprehensive income or loss (&#x201c;AOCI&#x201d;) represents the cumulative balance of other comprehensive income, net of tax, as of the balance sheet date. For CSX, AOCI is primarily the cumulative balance related to pension and other post-retirement benefit adjustments, interest rate derivatives and CSX's share of AOCI of equity method investees. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:115%"&gt;&#160;&#160;&#160;&#160;Changes in the AOCI balance by component are shown in the following table. Amounts reclassified in pension and other post-employment benefits to net earnings relate to the amortization of actuarial losses and are included in other income - net on the consolidated income statements. See Note 6, Employee Benefit Plans, for further information. Interest rate derivatives consist of forward starting interest rate swaps classified as cash flow hedges.

On April 14, 2021, in the first phase of the transaction, the Company closed on the conveyance of a permanent land easement for passenger rail operations. In second quarter 2021, the gain on this sale will be recognized in materials, supplies and other on the consolidated income statement. The Company anticipates closing on the remaining conveyances over the next two years. Funding for a portion of the transaction price remains subject to approval by the Virginia General Assembly and the Commonwealth. As of March 31, 2021, the carrying values of the assets subject to this transaction were not material.</us-gaap:SubsequentEventsTextBlock>

This estimated aggregate range is based upon currently available information and is subject to significant judgment and a variety of assumptions. Accordingly, the Company's estimate will change from time to time, and actual losses may vary significantly from the current estimate.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Fuel Surcharge Antitrust Litigation</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#160;&#160;&#160;&#160;In May 2007, class action lawsuits were filed against CSXT and three other U.S.-based Class I railroads alleging that the defendants' fuel surcharge practices relating to contract and unregulated traffic resulted from an illegal conspiracy in violation of antitrust laws. The class action lawsuits were consolidated into one case in federal court in the District of Columbia. In 2017, the District Court issued its decision denying class certification. On August 16, 2019, the U.S. Court of Appeals for the D.C. Circuit affirmed the District Court&#8217;s ruling.  </span></div><div style="text-align:justify"><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:115%">&#160;&#160;&#160;&#160;The consolidated case is now moving forward without class certification. Although a class was not certified, shippers other than those who brought the original lawsuit in 2007 must decide whether to bring their own individual claim against one or more railroads. Individual shipper claims filed to date have been consolidated into a separate case.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#160;&#160;&#160;&#160;CSXT believes that its fuel surcharge practices were arrived at and applied lawfully and that the case is without merit. Accordingly, the Company intends to defend itself vigorously. However, penalties for violating antitrust laws can be severe, and resolution of these matters individually or when aggregated could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">NOTE 5.&#160;&#160;&#160;&#160;Commitments and Contingencies, </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">continued</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Environmental</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#160;&#160;&#160;&#160;CSXT is indemnifying Pharmacia LLC, formerly known as Monsanto Company, ("Pharmacia") for certain liabilities associated with real estate located in Kearny, New Jersey along the Lower Passaic River (the &#8220;Property&#8221;). The Property, which was formerly owned by Pharmacia, is now owned by CSXT. CSXT's indemnification and defense duties arise with respect to several matters. The U.S. Environmental Protection Agency ("EPA"), using its CERCLA authority, seeks the investigation and cleanup of hazardous substances in the 17-mile Lower Passaic River Study Area (the "Study Area&#8221;). CSXT, on behalf of Pharmacia, and a significant number of other potentially responsible parties are together conducting a Remedial Investigation and Feasibility Study of the Study Area pursuant to an Administrative Settlement Agreement and Order on Consent with the EPA. Pharmacia&#8217;s share of responsibility, indemnified by CSXT, for the investigation and cleanup costs of the Study Area may be determined through various mechanisms including (a) an allocation and settlement with EPA; (b) litigation brought by EPA against non-settling parties; or (c) litigation among the responsible parties. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">            In March 2016, EPA issued its Record of Decision detailing the agency&#8217;s mandated remedial process for the lower 8 miles of the Study Area. Approximately 80 parties, including Pharmacia, are participating in an EPA-directed allocation and settlement process to assign responsibility for the remedy selected for the lower 8 miles of the Study Area. CSXT is participating in the EPA-directed allocation and settlement process on behalf of Pharmacia. At a later date, EPA will select a remedy for the remainder of the Study Area and is expected to again seek the participation of private parties to implement the selected remedy using EPA&#8217;s CERCLA authority to compel such participation, if necessary.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">            CSXT is also defending and indemnifying Pharmacia with regard to the Property in litigation filed by Occidental Chemical Corporation ("Occidental"), which is seeking to recover various costs. These costs include costs for the remedial design of the lower 8 miles of the Study Area, as well as anticipated costs associated with the future remediation of the lower 8 miles of the Study Area and potentially the entire Study Area. Alternatively, Occidental seeks to compel some, or all of the defendants to participate in the remediation of the Study Area. Pharmacia is one of approximately 110 defendants in this federal lawsuit filed by Occidental on June 30, 2018.</span></div>            CSXT is also defending and indemnifying Pharmacia in a cooperative natural resource damages assessment process related to the Property. Based on currently available information, the Company does not believe any indemnification or remediation costs potentially allocable to CSXT with respect to the Property and the Study Area would be material to the Company's financial condition, results of operations or liquidity.<span></span>

The Company&#8217;s performance obligation arises when it receives a bill of lading (&#8220;BOL&#8221;) 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. </span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:700;line-height:120%">NOTE 8. &#160;&#160;&#160;&#160;Revenues, </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">continued</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">The average transit time to complete a shipment is between 2 to 8 days depending on market.

Company's only financial instrument with fair values significantly different from their carrying amounts. The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party.

Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules.

<td class="text">Subsequent EventOn March 26, 2021, the Company entered into a comprehensive rail agreement to sell certain interests in three CSX-owned line segments to the Commonwealth of Virginia (&#8220;Commonwealth&#8221;) over three phases for a total of $525&#160;million. On April 14, 2021, in the first phase of the transaction, the Company closed on the conveyance of a permanent land easement for passenger rail operations. In second quarter 2021, the gain on this sale will be recognized in materials, supplies and other on the consolidated income statement. The Company anticipates closing on the remaining conveyances over the next two years. Funding for a portion of the transaction price remains subject to approval by the Virginia General Assembly and the Commonwealth. As of March 31, 2021, the carrying values of the assets subject to this transaction were not material.<span></span>

<td class="text">The Company generates revenue from 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&#8217;s performance obligation arises when it receives a bill of lading (&#8220;BOL&#8221;) 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. <div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">The average transit time to complete a shipment is between 2 to 8 days depending on market. Payments for transportation services are normally billed once a BOL is received and are generally due within 15 days after the invoice date. The Company recognizes revenue over transit time of freight as it moves from origin to destination. Revenue for services started but not completed at the reporting date is allocated based on the relative transit time in each reporting period, with the portion allocated for services subsequent to the reporting date considered remaining performance obligations.</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">The certain key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="padding-left:45pt;text-align:justify;text-indent:-9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt">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;</span></div><div style="padding-left:45pt;text-align:justify;text-indent:-9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt">Adjustments to revenue for billing corrections and billing discounts;</span></div><div style="padding-left:45pt;text-align:justify;text-indent:-9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt">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</span></div><div style="padding-left:45pt;text-align:justify;text-indent:-9pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:5.15pt">Incentive-based refunds to customers, which are primarily volume-related, are recorded as a reduction to revenue on the basis of the projected liability&#160;(this estimate is based on historical activity, current volume levels and forecasted future volume).</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Revenue related to interline transportation services that involve the services of another party, such as another railroad, is reported on a net basis.

The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities.

Such factors include, but are not limited to, interest rates, market conditions, credit ratings, values of similar financial instruments, size of the transaction, cash flow projections and comparable trades. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules.Interest Rate DerivativesThe Company&#8217;s forward starting interest rate swaps are carried at fair value and valued with assistance from a third party based upon pricing models using inputs observed from actively quoted markets. All of the inputs used to determine the fair value of the swaps are Level 2 inputs.<span></span>
