NOTE 1. Nature of Operations and Significant Accounting Policies
Background
CSX Corporation together with its subsidiaries ("CSX" or the “Company”), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based transportation services including traditional rail service, the transport of intermodal containers and trailers, as well as other transportation services such as rail-to-truck transfers and bulk commodity operations.
CSX's principal operating subsidiary, CSX Transportation, Inc. (“CSXT”), provides an important link to the transportation supply chain through its approximately 20,000 route mile rail network and serves major population centers in 26 states east of the Mississippi River, the District of Columbia and the Canadian provinces of Ontario and Quebec. The Company's intermodal business links customers to railroads via trucks and terminals. On June 1, 2022, CSX completed its acquisition of Pan Am Systems, Inc. (“Pan Am”), which is the parent company of Pan Am Railways, Inc. This acquisition expanded CSXT’s reach in the Northeastern United States. CSXT is also responsible for the Company's real estate sales, leasing, acquisition and management and development activities, substantially all of which are focused on supporting railroad operations.
Other entities
In addition to CSXT, the Company’s subsidiaries include Quality Carriers, Inc. ("Quality Carriers"), CSX Intermodal Terminals, Inc. (“CSX Intermodal Terminals”), Total Distribution Services, Inc. (“TDSI”), Transflo Terminal Services, Inc. (“Transflo”), CSX Technology, Inc. (“CSX Technology”) and other subsidiaries. Quality Carriers is the largest provider of bulk liquid chemicals truck transportation in North America. CSX Intermodal Terminals owns and operates a system of intermodal terminals, predominantly in the eastern United States and also performs drayage services (the pickup and delivery of intermodal shipments) for certain customers. TDSI serves the automotive industry with distribution centers and storage locations. Transflo connects non-rail served customers to the many benefits of rail by transferring products from rail to trucks. The biggest Transflo markets are chemicals and agriculture, which includes shipments of plastics and ethanol. CSX Technology and other subsidiaries provide support services for the Company.
Sale of Property Rights to the Commonwealth of Virginia
On March 26, 2021, the Company entered into a comprehensive agreement to sell certain property rights in three CSX-owned line segments to the Commonwealth of Virginia (“Commonwealth”) over three phases. The timing and amount of gains recognized were based on the allocation of fair value to each conveyance, the timing of conveyances and collectability. Over the course of this transaction, which was completed in 2022, total proceeds of $525 million were collected and total gains of $493 million were recognized. A gain of $20 million was recognized in first quarter 2022 related to the closing of the second phase.

Basis of Presentation
In the opinion of management, the accompanying consolidated financial statements contain all normal, recurring adjustments necessary to fairly present the consolidated financial statements and accompanying notes. Where applicable, prior year information has been reclassified to conform to the current presentation. Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted from these interim financial statements. CSX suggests that these financial statements be read in conjunction with the audited financial statements and the notes included in CSX's most recent annual report on Form 10-K and any subsequently filed current reports on Form 8-K.
Fiscal Year
The Company's fiscal periods are based upon the calendar year. Except as otherwise specified, references to “first quarter(s)” or “three months” indicate CSX's fiscal periods ending March 31, 2023 and March 31, 2022, and references to "year-end" indicate the fiscal year ended December 31, 2022.
New Accounting Pronouncements
In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. As the London Interbank Offered Rate ("LIBOR") will no longer be available beginning July 2023, this standard update provides practical expedients for contract modifications made as part of the transition from LIBOR to alternative reference rates. The guidance was effective upon issuance and at present can generally be applied through December 31, 2024. As of March 31, 2023, the Company has not applied the practical expedient to any contracts.

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

| First Quarters |  |
| 2023 | 2022 |  |  |
Numerator (Dollars in millions): |  |  |  |  |
Net Earnings | $ | 987 |  | $ | 859 |  |  |  |
Denominator (Units in millions): |  |  |  |  |
Average Common Shares Outstanding | 2,054 |  | 2,188 |  |  |  |
Other Potentially Dilutive Common Shares | 4 |  | 5 |  |  |  |
Average Common Shares Outstanding, Assuming Dilution | 2,058 |  | 2,193 |  |  |  |
Net Earnings Per Share, Basic | $ | 0.48 |  | $ | 0.39 |  |  |  |
Net Earnings Per Share, Assuming Dilution | $ | 0.48 |  | $ | 0.39 |  |  |  |

Basic earnings per share is based on the weighted-average number of shares of common stock outstanding. Earnings per share, assuming dilution, is based on the weighted-average number of shares of common stock outstanding and common stock equivalents adjusted for the effects of common stock that may be issued as a result of potentially dilutive instruments. CSX's potentially dilutive instruments are made up of equity awards including performance units and employee stock options.
When calculating diluted earnings per share, the potential shares that would be outstanding if all outstanding stock options were exercised are included. This number is different from outstanding stock options 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.

| First Quarters |  |
| 2023 | 2022 |  |  |
Antidilutive Stock Options Excluded from Diluted EPS (Units in millions) | 4 | 1 |  |  |

Share Repurchases
In July 2022, the share repurchase program announced in October 2020 was completed and the Company announced a $5 billion share repurchase program. Total repurchase authority remaining was $2.2 billion as of March 31, 2023.
Share repurchases may be made through a variety of methods including, but not limited to, open market purchases, purchases pursuant to Rule 10b5-1 plans, accelerated share repurchases and negotiated block purchases. The timing of share repurchases depends upon management's assessment of marketplace conditions and other factors, and the program remains subject to the discretion of the Board of Directors. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances. Shares are retired immediately upon repurchase. In accordance with the Equity Topic in the Accounting Standards Codification ("ASC"), the excess of repurchase price over par value is recorded in retained earnings.
During first quarters 2023 and 2022, the Company engaged in the following repurchase activities:

| First Quarters |  |
| 2023 | 2022 |  |  |
Shares Repurchased (Millions) | 35 |  | 29 |  |  |  |
Cost of Shares (Dollars in millions) | $ | 1,067 |  | $ | 1,016 |  |  |  |

Dividend Increase
On February 14, 2023, the Company's Board of Directors authorized a 10% increase in the quarterly cash dividend to $0.11 per common share effective March 2023.

NOTE 3. Stock Plans and Share-Based Compensation
Under CSX's share-based compensation plans, awards consist of performance units, stock options and restricted stock units for management and stock grants for directors. Share-based compensation expense for awards under share-based compensation plans is measured using the fair value of the award on the grant date and is recognized on a straight-line basis over the service period of the respective award. Alternatively, expense is recognized upon death or over an accelerated service period for retirement-eligible employees whose agreements allow for continued vesting upon retirement. Forfeitures are recognized as they occur. Total pre-tax expense and income tax benefits associated with share-based compensation are shown in the table below. Income tax benefits include impacts from option exercises and the vesting of other equity awards.

| First Quarters |  |
(Dollars in millions) | 2023 | 2022 |  |  |

Performance Units
Payouts will be made in CSX common stock with a payout range for most participants 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. The fair values of performance units granted to certain executive officers were calculated using a Monte-Carlo simulation model.
Measurement against goals related to both average annual operating income growth and CSX Cash Earnings ("CCE"), in each case excluding non-recurring items as defined in the plan, will each comprise 50% of the payout. As defined under the plan, CCE is a cash-flow based measure of economic profit that incentivizes strategic investments earning more than the required return and is calculated as CSX’s gross cash earnings (after-tax EBITDA) minus the required return on gross operating assets.
Stock Options
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. These awards are time-based and are not based upon attainment of performance goals. The fair values of stock option awards were estimated at the grant date using the Black-Scholes valuation model.
Restricted Stock Units
The restricted stock units awarded vest over three years in equal installments each year on the anniversary of the grant date and are settled in CSX common stock on a one-for-one basis. These awards are time-based and are not based upon CSX's attainment of performance goals.
For more information related to the Company's outstanding long-term incentive compensation, see CSX's most recent annual report on Form 10-K.

NOTE 4. Casualty, Environmental and Other Reserves
Personal injury and environmental reserves are considered critical accounting estimates due to the need for management judgment. Casualty, environmental and other reserves are provided for in the consolidated balance sheets as shown in the table below.

(Dollars in millions) | Current | Long-term | Total |  | Current | Long-term | Total
Casualty: |  |  |  |  |  |  |

Total | $ | 151 |  | $ | 287 |  | $ | 438 |  |  | $ | 144 |  | $ | 292 |  | $ | 436 |

These liabilities are accrued when probable and reasonably estimable in accordance with the Contingencies Topic in the ASC. Actual settlements and claims received could differ, and final outcomes of these matters cannot be predicted with certainty. Considering the legal defenses currently available, the liabilities that have been recorded and other factors, it is the opinion of management that none of these items individually, when finally resolved, will have a material adverse effect on the Company's financial condition, results of operations or liquidity. Should a number of these items occur in the same period, however, their combined effect could be material in that particular period.

Casualty reserves of $193 million and $194 million as of March 31, 2023 and December 31, 2022, respectively, represent accruals for personal injury, occupational disease and occupational injury claims primarily related to railroad operations. The Company's self-insured retention amount for casualty claims is $100 million per occurrence. Currently, no individual claim is expected to exceed the self-insured retention amount.
Personal Injury
Personal injury reserves represent liabilities for employee work-related and third-party injuries. Work-related injuries for CSXT employees are primarily subject to the Federal Employers’ Liability Act (“FELA”). CSXT retains an independent actuary to assist management in assessing the value of personal injury claims. An analysis is performed by the actuary quarterly and is reviewed by management. This analysis did not result in a material adjustment to the personal injury reserve in the quarters ended March 31, 2023 or March 31, 2022.
Occupational
Occupational reserves represent liabilities arising from allegations of exposure to certain materials in the workplace (such as solvents, soaps, chemicals and diesel fumes), past exposure to asbestos or allegations of chronic physical injuries resulting from work conditions (such as repetitive stress injuries). The Company retains an independent actuary to analyze the Company’s historical claim filings, settlement amounts, and dismissal rates to assist in determining future anticipated claim filing rates and average settlement values. This analysis is performed by the actuary and reviewed by management quarterly. The analysis did not result in a material adjustment to the occupational reserve in the quarters ended March 31, 2023 or March 31, 2022.

NOTE 4. Casualty, Environmental and Other Reserves, continued
Environmental
Environmental reserves were $162 million and $161 million as of March 31, 2023, and December 31, 2022, respectively. The Company is a party to various proceedings related to environmental issues, including administrative and judicial proceedings involving private parties and regulatory agencies. The Company has been identified as a potentially responsible party at approximately 240 environmentally impaired sites. Many of these are, or may be, subject to remedial action under the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), also known as the Superfund Law, or similar state statutes. Most of these proceedings arose from environmental conditions on properties used for ongoing or discontinued railroad operations. A number of these proceedings, however, are based on allegations that the Company, or its predecessors, sent hazardous substances to facilities owned or operated by others for treatment, recycling or disposal. In addition, some of the Company's land holdings were leased to others for commercial or industrial uses that may have resulted in releases of hazardous substances or other regulated materials onto the property and could give rise to proceedings against the Company.
In any such proceedings, the Company is subject to environmental clean-up and enforcement actions under the Superfund Law, as well as similar state laws that may impose joint and several liability for clean-up and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. These costs could be substantial.
The Company reviews its role with respect to each site identified at least quarterly. Based on management's review process, amounts have been recorded to cover contingent anticipated future environmental remediation costs with respect to each site to the extent such costs are reasonably estimable and probable. Payments related to these liabilities are expected to be made over the next several years. Environmental remediation costs are included in purchased services and other on the consolidated income statements.
Currently, the Company does not possess sufficient information to reasonably estimate the amounts of additional liabilities, if any, on some sites until completion of future environmental studies. In addition, conditions that are currently unknown could, at any given location, result in additional exposure, the amount and materiality of which cannot presently be reasonably estimated. Based upon information currently available, however, the Company believes its environmental reserves accurately reflect the estimated cost of remedial actions currently required.
Other
Other reserves were $83 million and $81 million as of March 31, 2023 and December 31, 2022, respectively. Other reserves include liabilities for various claims, such as automobile, property, general liability, workers' compensation and longshoremen disability claims.

NOTE 5. Commitments and Contingencies
Insurance
The Company maintains insurance programs with substantial limits for property damage, including resulting business interruption, and third-party liability. A certain amount of risk is retained by the Company on each insurance program. Under its property insurance program, the Company retains all risk up to $100 million per occurrence for losses from floods and named windstorms and up to $75 million per occurrence for other property losses. For third-party liability claims, the Company retains all risk up to $100 million per occurrence. As CSX negotiates insurance coverage above its full self-retention amounts, it retains a percentage of risk at various layers of coverage. While the Company believes its insurance coverage is adequate, future claims could exceed existing insurance coverage or insurance may not continue to be available at commercially reasonable rates.
Legal
The Company is involved in litigation incidental to its business and is a party to a number of legal actions and claims, various governmental proceedings and private civil lawsuits, including, but not limited to, those related to fuel surcharge practices, tax matters, environmental and hazardous material exposure matters, FELA and labor claims by current or former employees, other personal injury or property claims and disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for compensatory as well as punitive damages and others are, or are purported to be, class actions. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the legal defenses available and liabilities that have been recorded along with applicable insurance, it is currently the opinion of management that none of these pending items 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.
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 $3 million to $22 million in aggregate at March 31, 2023. This estimated aggregate range is based upon currently available information and is subject to significant judgment and a variety of assumptions. Accordingly, the Company's estimate will change from time to time, and actual losses may vary significantly from the current estimate.
Fuel Surcharge Antitrust Litigation
In May 2007, class action lawsuits were filed against CSXT and three other U.S.-based Class I railroads alleging that the defendants' fuel surcharge practices relating to contract and unregulated traffic resulted from an illegal conspiracy in violation of antitrust laws. The class action lawsuits were consolidated into one case in federal court in the District of Columbia. In 2017, the District Court issued its decision denying class certification. On August 16, 2019, the U.S. Court of Appeals for the D.C. Circuit affirmed the District Court’s ruling. The consolidated case is now moving forward without class certification. Although the class was not certified, individual shippers have since brought claims against the railroads, which have been consolidated into a separate case.
CSXT believes that its fuel surcharge practices were arrived at and applied lawfully and that the case is without merit. Accordingly, the Company intends to defend itself vigorously. However, penalties for violating antitrust laws can be severe, and resolution of these matters individually or when aggregated could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.

CSXT is indemnifying Pharmacia LLC, formerly known as Monsanto Company, ("Pharmacia") for certain liabilities associated with real estate located in Kearny, New Jersey along the Lower Passaic River (the “Property”). The Property, which was formerly owned by Pharmacia, is now owned by CSXT. CSXT's indemnification and defense duties arise with respect to several matters. The U.S. Environmental Protection Agency ("EPA"), using its CERCLA authority, seeks the investigation and cleanup of hazardous substances in the 17-mile Lower Passaic River Study Area (the "Study Area”). CSXT, on behalf of Pharmacia, and a significant number of other potentially responsible parties are together conducting a Remedial Investigation and Feasibility Study of the Study Area pursuant to an Administrative Settlement Agreement and Order on Consent with the EPA. Pharmacia’s share of responsibility, indemnified by CSXT, for the investigation and cleanup costs of the Study Area may be determined through various mechanisms including (a) an allocation and settlement with EPA; (b) litigation brought by EPA against non-settling parties; or (c) litigation among the responsible parties.
For the lower 8 miles of the Study Area, EPA issued its Record of Decision detailing the agency’s mandated remedial process in March 2016. 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. For the remainder of the Study Area, EPA has selected an interim remedy in a Record of Decision dated September 28, 2021.
On March 2, 2022, EPA issued a Notice Letter to Pharmacia, Occidental Chemical Corporation and eight other parties alleging they are liable under Section 107(a) of CERCLA for releases or threatened releases of hazardous substances and requesting each party, individually or collectively, submit good faith offers to EPA in connection with the Study Area. CSX, on behalf of Pharmacia, responded to the Notice Letter and submitted a good faith offer to EPA on June 27, 2022, following meetings with a mediator from EPA’s Conflict Prevention and Resolution Center. Negotiations with EPA and other parties to resolve this matter continue. On March 2, 2023, the EPA issued an administrative order requiring Occidental Chemical Corporation to design the interim remedy for the remainder of the Study Area.
CSXT is also defending and indemnifying Pharmacia with regard to the Property in litigation filed by Occidental Chemical Corporation, which is seeking to recover various costs. These costs include costs for the remedial design of the lower 8 miles of the Study Area, as well as anticipated costs associated with the future remediation of the entire Study Area. Alternatively, Occidental seeks to compel some, or all of the defendants to participate in the remediation of the Study Area. Pharmacia is one of approximately 110 defendants in this federal lawsuit filed by Occidental on June 30, 2018. CSXT is also defending and indemnifying Pharmacia in a cooperative natural resource damages assessment process related to the Property.
Based on currently available information, the Company does not believe its share of remediation costs as determined by the EPA-directed allocation with respect to the Property and the Study Area would be material to the Company's financial condition, results of operations or liquidity.

NOTE 6. Employee Benefit Plans
The Company sponsors defined benefit pension plans principally for salaried, management personnel. The CSX Pension Plan, the largest plan based on benefit obligation, was closed to new participants beginning in 2020.
Independent actuaries compute the amounts of liabilities and expenses relating to these plans subject to the assumptions that the Company determines are appropriate based on historical trends, current market rates and future projections. These amounts are reviewed by management. Only the service cost component of net periodic benefit costs is included in labor and fringe expense on the consolidated income statement. All other components of net periodic benefit cost are included in other income - net.

| Pension Benefits Cost
| First Quarters |  |
(Dollars in millions) | 2023 |  | 2022 |  |  |  |

Qualified pension plan obligations are funded in accordance with regulatory requirements and with an objective of meeting or exceeding minimum funding requirements necessary to avoid restrictions on flexibility of plan operation and benefit payments. No c ontributions to the Company's qualified pension plans are expected in 2023.

Interest Rate Derivatives
Fair Value Hedges
In first quarter 2022, CSX entered into five separate fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to the Secured Overnight Financing Rate on a cumulative $800 million of fixed rate outstanding notes which are due between 2036 and 2040. The cumulative fair value of these swaps, which is included in other long-term liabilities on the consolidated balance sheet, was a liability of $103 million and $118 million as of March 31, 2023, and December 31, 2022, respectively. The associated cumulative adjustment to the hedged notes is included in long-term debt. Gains and losses resulting from changes in fair value of the interest rate swaps offset changes in the fair value of the hedged portion of the underlying debt with no gain or loss recognized due to hedge ineffectiveness. The difference in the net fixed-to-float interest settlement on the derivatives is recognized in interest expense and was not material in first quarter 2023 or 2022. The swaps will expire in 2032. If settled early, the remaining cumulative fair value adjustment to the hedged notes will be amortized over the remaining life of the associated notes. The amounts recorded in long-term debt on the consolidated balance sheet related to these fair value hedges is summarized in the table below.

(Dollars in millions) | March 31, 2023 | December 31, 2022

Cash Flow Hedges
The unsettled aggregate notional value of forward starting interest rate swaps, classified as cash flow hedges, executed in 2020 is $340 million. These swaps were effected to hedge the benchmark interest rate associated with future interest payments related to the anticipated refinancing of $850 million of 3.25% notes due in 2027. As of March 31, 2023, and December 31, 2022, the asset value of the forward starting interest rate swaps was $124 million and $127 million, respectively, and was recorded in other long-term assets on the consolidated balance sheet. Unrealized gains or losses associated with changes in the fair value of the hedge are recorded net of tax in accumulated other comprehensive income (“AOCI”) on the consolidated balance sheet. Unless settled early, the remainder of the swaps will expire in 2027 and the unrealized gain or loss in AOCI will be recognized in earnings as an adjustment to interest expense over the same period during which the hedged transaction affects earnings. Unrealized amounts, recorded net of tax in other comprehensive income, related to the hedge were a loss of $3 million in first quarter 2023 and gain of $21 million in first quarter 2022.
See Note 9, Fair Value Measurements, and Note 10, Other Comprehensive Income (Loss), for additional information about the Company's hedges.
Credit Facility
On February 28, 2023, CSX replaced its existing $1.2 billion unsecured revolving credit facility with a new $1.2 billion unsecured revolving credit facility backed by a diverse syndicate of banks. This facility allows same-day borrowings at floating interest rates, based on Secured Overnight Financing Rate ("SOFR") or an agreed-upon replacement reference rate, plus a spread that depends upon CSX's senior unsecured debt ratings. This facility expires in February 2028. As of March 31, 2023, the Company had no outstanding balances under this facility.
Commitment fees and interest rates payable under the facility were similar to fees and rates available to comparably rated investment-grade borrowers. As of first quarter 2023, CSX was in compliance with all covenant requirements under this facility.
Commercial Paper
Under its commercial paper program, which is backed by the revolving credit facility, the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount of $1.0 billion outstanding at any one time. Proceeds from issuances of the notes are expected to be used for general corporate purposes. At March 31, 2023, the Company had no outstanding debt under the commercial paper program.

NOTE 9. Fair Value Measurements
Investments
The Company's investment assets are carried at fair value on the consolidated balance sheet in accordance with the Fair Value Measurements and Disclosures Topic in the ASC. They are valued with assistance from a third-party trustee and consist of fixed income mutual funds, corporate bonds, government securities and short-term time deposits. The fixed income mutual funds are valued at the net asset value of shares held based on quoted market prices determined in an active market, which are Level 1 inputs. The corporate bonds and government securities are valued using broker quotes that utilize observable market inputs, which are Level 2 inputs. The carrying amount of time deposits as reported in the consolidated balance sheet, using Level 2 inputs, approximates fair value due to their short-term nature. Unrealized losses as of March 31, 2023 were not material. The Company believes any impairment of investments held with gross unrealized losses to be temporary and not the result of credit risk.
The Company's investment assets are carried at fair value on the consolidated balance sheets as summarized in the following table.

Long-term Debt
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 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 majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.
The fair value and carrying value of the Company's long-term debt is as follows:

(Dollars in millions) | March 31, 2023 |  | December 31, 2022
Long-term Debt (Including Current Maturities): |  |  |

Carrying Value | 17,922 |  |  | 18,047 |

Interest Rate Derivatives
The Company’s fixed-to-floating and forward starting interest rate swaps are carried at their respective fair values, which are determined with assistance from a third party based upon pricing models using inputs observed from actively quoted markets. All of the inputs used to determine the fair value of the swaps are Level 2 inputs. The fair value of the Company’s fixed-to-floating interest rate swaps was a liability of $103 million and $118 million as of March 31, 2023, and December 31, 2022, respectively. The fair value of the Company’s forward starting interest rate swap asset was $124 million and $127 million as of March 31, 2023, and December 31, 2022, respectively.

NOTE 10. Other Comprehensive Income (Loss)
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 derivative activity and other adjustments. Total comprehensive earnings represent the activity for a period net of tax and was $989 million and $890 million for first quarters 2023 and 2022, respectively.
While total comprehensive earnings is the activity in a period and is largely driven by net earnings in that period, AOCI represents the cumulative balance of other comprehensive income, net of tax, as of the balance sheet date. 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. See Note 7, Debt and Credit Agreements, for further information. Other primarily represents CSX's share of AOCI of equity method investees. Amounts reclassified in other to net earnings are included in purchased services and other or equipment and other rents on the consolidated income statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
First Quarter 2023
Revenue
Total revenue increased 9% in first quarter 2023 when compared to first quarter 2022 primarily due to volume growth in coal and merchandise, higher fuel recovery, and pricing gains in merchandise and intermodal, partially offset by lower intermodal volume.
Merchandise Volume
Chemicals - Decreased due to lower shipments of materials used in making plastics, partially offset by higher shipments of energy-related commodities.
Agricultural and Food Products - Increased due to higher shipments of feed grain for both the domestic and export markets.
Automotive - Increased due to higher North American vehicle production as semiconductor availability has improved.
Minerals - Increased due to higher shipments of aggregates and cement driven by increased road construction and other infrastructure-related activities.
Forest Products - Increased due to higher shipments of building products, supported by strength in multi-family residential construction.
Metals and Equipment - Increased due to higher scrap and steel shipments, as well as stronger equipment shipments.
Fertilizers - Decreased due to declines in short-haul shipments, which were partially offset by slight increases in long-haul phosphate shipments.
Intermodal Volume
Lower volume was primarily due to decreased international shipments driven by high inventory levels and lower imports. Domestic shipments also decreased primarily due to the impacts of a softening truck market.
Coal Volume
Export coal increased due to higher shipments of metallurgical and thermal coal, partially due to the prior year impact from reduced capacity at Curtis Bay coal pier. Domestic coal increased due to higher shipments of utility coal including the benefit of replenishing stockpiles as well as higher steel and industrial shipments.
Trucking Revenue
Trucking revenue increased $3 million versus prior year due to higher fuel surcharge.
Other Revenue
Other revenue was $24 million lower primarily resulting from lower intermodal storage and equipment usage, partially offset by increases in demurrage and higher affiliate revenue.

Expenses
Expenses of $2.2 billion increased $111 million, or 5%, in first quarter 2023 when compared to the first quarter 2022.
Labor and Fringe expense increased $31 million due to the following:
•An increase of $39 million was driven by inflation.
•Incentive compensation costs decreased $31 million due to the impacts of accelerated expense for eligible employees in the prior year as well as lower expected payouts.
•Other costs increased $23 million primarily due to increased headcount and training costs.
Purchased Services and Other expense increased $13 million due to the following:
•Operating support costs increased $35 million primarily as a result of inflation, higher scheduled locomotive maintenance costs and increased coal and merchandise volume. These increases were partially offset by lower intermodal expenses.
•Other costs decreased $22 million as a $46 million insurance recovery and the impact of prior year environmental reserve adjustments were partially offset by the inclusion of Pan Am's operations and other non-significant items.
Depreciation and Amortization expense increased $33 million primarily as the result of a 2022 equipment depreciation study as well as a larger asset base.
Fuel costs increased $33 million primarily resulting from a 6% increase in locomotive fuel prices as well as higher fuel consumption.
Equipment and Other Rents expense decreased $18 million primarily driven by lower net car hire costs resulting from improved days per load across all markets.
Gains on Property Dispositions decreased to $8 million from $27 million in the prior year. First quarter 2022 included gains of $20 million related to the sale of property rights to the Commonwealth of Virginia under a multi-phase agreement.
Interest Expense
Interest expense increased $22 million primarily due to higher average debt balances and higher interest rates.
Other Income - Net
Other income - net increased $15 million primarily due to higher interest income, partially offset by a decrease in net pension benefit credits.
Income Tax Expense
Income tax expense increased $47 million mostly due to higher earnings before income taxes.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Non-GAAP Measures - Unaudited
CSX reports its financial results in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). CSX also uses certain non-GAAP measures that fall within the meaning of Securities and Exchange Commission Regulation G and Regulation S-K Item 10(e), which may provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP measures do not have standardized definitions and are not defined by U.S. GAAP. Therefore, CSX’s non-GAAP measures are unlikely to be comparable to similar measures presented by other companies. The presentation of these non-GAAP measures should not be considered in isolation from, as a substitute for, or as superior to the financial information presented in accordance with GAAP. Reconciliations of non-GAAP measures to corresponding GAAP measures are below.
Free Cash Flow
Management believes that free cash flow is supplemental information useful to investors as it is important in evaluating the Company’s financial performance. More specifically, free cash flow measures cash generated by the business after reinvestment. This measure represents cash available for both equity and bond investors to be used for dividends, share repurchases or principal reduction on outstanding debt. Free cash flow is calculated by using net cash from operations and adjusting for property additions and proceeds and advances from property dispositions. Free cash flow should be considered in addition to, rather than a substitute for, cash provided by operating activities. The decrease in free cash flow before dividends from the prior year of $160 million is due to higher property additions and less cash from operating activities.
The following table reconciles cash provided by operating activities (GAAP measure) to free cash flow, before dividends (non-GAAP measure).

| Three Months
(Dollars in millions) | 2023 | 2022
Net cash provided by operating activities (a) | $ | 1,251 |  | $ | 1,299 |
Property Additions | (443) |  | (331) |
Proceeds and Advances from Property Dispositions | 8 |  | 8 |
Free Cash Flow (before payment of dividends) | $ | 816 |  | $ | 976 |

(a) Net Cash Provided by Operating Activities for three months ended March 31, 2023, includes the impact of $232 million in payments of retroactive wages and bonuses related to finalized labor agreements.
Operating Statistics (Estimated)
The Company is committed to continuous improvement in safety and service performance through training, innovation and investment. Training and safety programs are designed to prevent incidents that can adversely impact employees, customers and communities. Technological innovations that can detect and avoid many types of human factor incidents are designed to serve as an additional layer of protection for the Company's employees. Continued capital investment in the Company's assets, including track, bridges, signals, equipment and detection technology also supports safety performance.
The FRA train accident rate of 3.47 in first quarter 2023 increased by 20% compared to prior year. The personal injury frequency index of 1.04 increased 27% compared to prior year. Safety is a guiding principle at CSX, and the Company remains focused on instilling safety culture, especially in new hires. CSX is committed to reducing risk and enhancing the overall safety of its employees, customers and communities in which the Company operates.

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

LIQUIDITY AND CAPITAL RESOURCES
The following are material changes in the significant cash flows, sources of cash and liquidity, capital investments, consolidated balance sheets and working capital, which provide an update to the discussion included in CSX's most recent annual report on Form 10-K.
Material Changes in Significant Cash Flows
Significant Cash Flows
The following chart highlights the operating, investing and financing components of the net decreases of $667 million and $303 million in cash and cash equivalents for three months ended 2023 and 2022, respectively.
•Cash provided by operating activities decreased $48 million primarily driven by unfavorable working capital activities, including the payments of $232 million for retroactive wages and bonuses related to finalized labor agreements. This decrease was partially offset by higher cash-generating income.
•Cash used in investing activities increased $112 million primarily as a result of higher property additions and higher net purchases of short-term investments.
•Cash used in financing activities increased $204 million driven by higher debt repayments and increased share repurchases.
Sources of Cash and Liquidity and Uses of Cash
As of the end of first quarter 2023, CSX had $1.5 billion of cash, cash equivalents and short-term investments. CSX uses current cash balances for general corporate purposes, which may include capital expenditures, working capital requirements, reduction or refinancing of outstanding indebtedness, redemptions and repurchases of CSX common stock, dividends to shareholders, acquisitions and other business opportunities, and contributions to the Company's qualified pension plan. See Note 7, Debt and Credit Agreements.
The Company has multiple sources of liquidity, including cash generated from operations and financing sources. The Company filed a shelf registration statement with the SEC on February 16, 2022, which may be used to issue debt or equity securities at CSX’s discretion, subject to market conditions and CSX Board authorization. While CSX seeks to give itself flexibility with respect to cash requirements, there can be no assurance that market conditions would permit CSX to sell such securities on acceptable terms at any given time, or at all. During the three months ended 2023, CSX did not issue any long-term debt.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
CSX has a $1.2 billion unsecured, revolving credit facility backed by a diverse syndicate of banks that expires in February 2028. At March 31, 2023, the Company had no outstanding balances under this facility. The Company also has a commercial paper program, backed by the revolving credit facility, under which the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount of $1.0 billion outstanding at any one time. At March 31, 2023, the Company had no outstanding debt under the commercial paper program.
Planned capital investments for 2023 are expected to be approximately $2.3 billion. Of the 2023 investment, approximately 75% is expected to be used to sustain the core infrastructure and operating equipment. The remaining amounts will be used to promote profitable growth, including projects supporting service enhancements and productivity. CSX intends to fund capital investments primarily through cash generated from operations.
Material Changes in the Consolidated Balance Sheets and Working Capital
Consolidated Balance Sheets
Total assets decreased $434 million from year end primarily due to the $667 million decrease in cash as noted above. This decrease was partially offset by a $64 million increase in accounts receivable, $42 million of which relates to an insurance recovery, as well as a $51 million increase in net property consistent with planned capital expenditures.
Total liabilities decreased $143 million from year end primarily due to a $340 million decrease in labor and fringe benefits payable and a $140 million decrease in current debt driven by the maturity of secured equipment notes. The decrease in labor and fringe benefits payable was driven by payouts of accrued retroactive wages and bonuses as well as incentive compensation. These decreases were partially offset by an increase in income and other taxes payable of $250 million due to the timing of tax payments. Total shareholders' equity decreased $291 million from year end primarily driven by share repurchases of $1.1 billion and dividends paid of $226 million, partially offset by net earnings of $987 million.
Working capital is considered a measure of a company's ability to meet its short-term needs. CSX had a working capital surplus of $1.0 billion as of March 31, 2023 and $1.4 billion as of December 31, 2022. This decrease of $344 million since year end is primarily due to cash paid for share repurchases of $1.1 billion, property additions of $443 million and dividends paid of $226 million, partially offset by cash from operations. The Company's working capital balance varies due to factors such as the timing of scheduled debt payments and changes in cash and cash equivalent balances as discussed above. The Company continues to maintain adequate liquidity to satisfy current liabilities and maturing obligations when they come due. CSX has sufficient financial capacity, including its revolving credit facility, commercial paper program and shelf registration statement to manage its day-to-day cash requirements and any anticipated obligations. The Company from time to time accesses the credit markets for additional liquidity.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
CSX is committed to returning cash to shareholders and maintaining an investment-grade credit profile. Capital structure, capital investments and cash distributions, including dividends and share repurchases, are reviewed at least annually by the Board of Directors. Management's assessment of market conditions and other factors guides the timing and volume of repurchases. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances.
Completed Transactions
Acquisition of Pan Am Systems, Inc.
On June 1, 2022, CSX acquired Pan Am for a purchase price of $600 million. The results of Pan Am's operations and its cash flows were consolidated prospectively.
Sale of Property Rights to the Commonwealth of Virginia
On March 26, 2021, the Company entered into a comprehensive agreement to sell certain property rights in three CSX-owned line segments to the Commonwealth of Virginia (“Commonwealth”) over three phases. The timing and amount of gains recognized were based on the allocation of fair value to each conveyance, the timing of conveyances and collectability. Over the course of this transaction, which was completed in 2022, total proceeds of $525 million were collected and total gains of $493 million were recognized. A gain of $20 million was recognized in first quarter 2022 related to the closing of the second phase.
Guaranteed Notes Issued By CSXT
In 2007, CSXT, a wholly-owned subsidiary of CSX Corporation, issued in a registered public offering $381 million of equipment notes, which were fully and unconditionally guaranteed by CSX Corporation. These notes matured on January 15, 2023.
In accordance with SEC rules, including amendments adopted in 2020, CSX is not required to present separate condensed consolidating financial information for wholly-owned subsidiaries who issued or guaranteed notes. Additionally, presentation of combined summary financial information regarding subsidiary issuers and guarantors is not required because the assets, liabilities and results of operations of the combined issuers and guarantors of the notes are not materially different from the corresponding amounts presented in the consolidated financial statements.
LABOR AGREEMENTS
Approximately 17,300 of the Company's approximately 22,600 employees are members of a rail labor union. As of December 2, 2022, all 12 rail unions at CSX that participated in national bargaining were covered by national agreements with the Class I railroads and CSX-specific agreements that will remain in effect through December 31, 2024.
