NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
NOTE 1. Nature of Operations and Significant Accounting Policies
Background
CSX Corporation (“CSX”), together with its subsidiaries (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 and the transport of intermodal containers and trailers.
CSX's principal operating subsidiary, CSX Transportation, Inc. (“CSXT”), provides an important link to the transportation supply chain through its approximately 20,500 route mile rail network, which serves major population centers in 23 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.
CSXT is also responsible for the Company's real estate sales, leasing, acquisition and management and development activities. In addition, as substantially all real estate sales, leasing, acquisition and management and development activities are focused on supporting railroad operations, all results of these activities are included in operating income.
Other entities
In addition to CSXT, the Company’s subsidiaries include 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. 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 and trucking dispatch operations. 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 include shipments of plastics and ethanol. CSX Technology and other subsidiaries provide support services for the Company.
Basis of Presentation
In the opinion of management, the accompanying consolidated financial statements contain all normal, recurring adjustments necessary to fairly present the following:

• | Consolidated income statements for the quarter ended March 31, 2019 and March 31, 2018;

• | Condensed consolidated comprehensive income statements for the quarter ended March 31, 2019 and March 31, 2018;

• | Consolidated balance sheets at March 31, 2019 and December 31, 2018;

• | Consolidated cash flow statements for the three months ended March 31, 2019 and March 31, 2018; and

• | Consolidated statements of changes in shareholders' equity for the three months ended March 31, 2019 and March 31, 2018.

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.

NOTE 1. Nature of Operations and Significant Accounting Policies, continued
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, 2019 and March 31, 2018, and references to "year-end" indicate the fiscal year ended December 31, 2018.
New Accounting Pronouncements
Pronouncements adopted in 2019
In February 2016, the FASB issued ASU, Leases, which requires lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability. Lessor accounting under the standard is substantially unchanged. Additional qualitative and quantitative disclosures are also required. CSX adopted the standard effective January 1, 2019 using the cumulative-effect adjustment transition method, which applies the provisions of the standard at the effective date without adjusting the comparative periods presented. The Company adopted the following practical expedients and elected the following accounting policies related to this standard update:

• | Carry forward of historical lease classifications and current accounting treatment for existing land easements;

• | Short-term lease accounting policy election allowing lessees to not recognize right-of-use assets and liabilities for leases with a term of 12 months or less; and

• | The option to not separate lease and non-lease components for certain equipment lease asset categories such as freight car, vehicles and work equipment.

Adoption of this standard resulted in the recognition of operating lease right-of-use assets and corresponding lease liabilities of $534 million on the consolidated balance sheet as of January 1, 2019. This amount is lower than previous estimates due to a lease amendment. The Company’s accounting for finance leases remained substantially unchanged. The standard did not materially impact operating results or liquidity. Disclosures related to the amount, timing and uncertainty of cash flows arising from leases are included in Note 5, Leases.
Pronouncements to be adopted
In June 2016, the FASB issued ASU Measurement of Credit Losses on Financial Instruments, which replaces current methods for evaluating impairment of financial instruments not measured at fair value, including trade accounts receivable and certain debt securities, with a current expected credit loss model. CSX will adopt this new standard update effective January 1, 2020, and does not expect it to have a material effect on the Company's results of operations.

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
| 2019 | 2018
Numerator (Dollars in millions): |  |
Net Earnings | $ | 834 |  | $ | 695 |
Denominator (Units in millions): |  |
Average Common Shares Outstanding | 814 |  | 885 |
Other Potentially Dilutive Common Shares | 3 |  | 3 |
Average Common Shares Outstanding, Assuming Dilution | 817 |  | 888 |
Net Earnings Per Share, Basic | $ | 1.02 |  | $ | 0.78 |
Net Earnings Per Share, Assuming Dilution | $ | 1.02 |  | $ | 0.78 |

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. Approximately 600 thousand and 800 thousand of total average outstanding stock options for the first quarters ended March 31, 2019 and March 31, 2018, respectively, were excluded from the diluted earnings per share calculation because their effect was antidilutive.
Share Repurchases
In February 2018, the Company announced an increase to the $1.5 billion share repurchase program first announced in October 2017, bringing the total authorized to $5 billion. This program was completed on January 16, 2019. Also on January 16, 2019, the Company announced a new $5 billion share repurchase program. During the first quarters of 2019 and 2018, the Company repurchased approximately $796 million, or 12 million shares, and $836 million, or 15 million shares, respectively.
Under an accelerated share repurchase agreement executed in January 2018, the Company made a prepayment of $150 million to a financial institution and received an initial delivery of shares valued at $120 million. The remaining balance of $30 million was settled through receipt of additional shares in February 2018 with the final net number of shares calculated based on the volume-weighted average price of the Company's common stock over the term of the agreement, less a discount. Approximately 3 million total shares were repurchased under the agreement.

(Unaudited)
NOTE 2. Earnings Per Share, continued
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 ASC, the excess of repurchase price over par value is recorded in retained earnings.
Dividend Increase
On February 6, 2019, the Company announced a 9 percent increase to the quarterly dividend from $0.22 per share of common stock to $0.24 per share of common stock, payable on March 15, 2019 to shareholders of record at the close of business on February 28, 2019.
NOTE 3. Share-Based Compensation
Under CSX's share-based compensation plans, awards consist of performance units, restricted stock awards, restricted stock units and stock options for management and stock grants for directors. Awards granted under the various programs are determined and approved by the Compensation Committee of the Board of Directors or, in certain circumstances, by the Chief Executive Officer for 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 Committee.
Share-based compensation expense for awards under share-based compensation plans and purchases made as part of the employee stock purchase plan is measured using the fair value of the award on the grant date and is recognized on a straight-line basis over the service period of the respective award. 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.

Long-term Incentive Plan
On February 6, 2019, the Company granted approximately 300 thousand performance units to certain employees under a new long-term incentive plan ("LTIP") for the years 2019 through 2021, which was adopted under the CSX Stock and Incentive Award Plan. During first quarter 2018, approximately 350 thousand performance units were granted pursuant to the corresponding LTIP.
Payouts of performance units for the cycle ending with fiscal year 2021 will be based on the achievement of goals related to both operating ratio and free cash flow, in each case excluding non-recurring items as disclosed in the Company's financial statements. The cumulative operating ratio and cumulative free cash flow over the plan period will each comprise 50% of the payout and will be measured independently of the other.
Grants were made in performance units, with each unit representing the right to receive one share of CSX common stock, and payouts will be made in CSX common stock. 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 225%, based upon the Company's total shareholder return relative to specified comparable groups over the performance period. The fair values of the performance units awarded during the quarters ended March 31, 2019 and March 31, 2018 were calculated using a Monte-Carlo simulation model with the following weighted-average assumptions:

| First Quarters
| 2019 | 2018
Weighted-average assumptions used: |  |
Annual dividend yield | 1.4 | % | 1.6 | %
Risk-free interest rate | 2.5 | % | 2.3 | %
Annualized volatility | 27.63 | % | 29.15 | %
Expected life (in years) | 2.9 |  | 2.9 |

Stock Options
Also, on February 6, 2019, the Company granted approximately 843 thousand stock options along with the corresponding LTIP. The fair value of stock options on the date of grant was $17.45 per option, which 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 quarter 2018, approximately 950 thousand stock options were granted pursuant to the corresponding LTIP.

Restricted Stock Units
Finally, on February 6, 2019, the Company granted approximately 65 thousand restricted stock units along with the corresponding LTIP. The restricted stock units vest three years after the date of grant. Participants receive cash dividend equivalents on the unvested shares during the restriction period. These awards are time-based and are not based upon CSX's attainment of operational targets. For information related to the Company's other outstanding long-term incentive compensation, see CSX's most recent annual report on Form 10-K. During first quarter 2018, approximately 85 thousand restricted stock units were granted pursuant to the corresponding LTIP. Restricted stock units are paid-out in CSX common stock on a one-for-one basis.
Employee Stock Purchase Plan
In May 2018, shareholders approved the 2018 CSX Employee Stock Purchase Plan (“ESPP”) for the benefit of Company employees. The Company registered 4 million shares of common stock that may be issued pursuant to this plan. Under the ESPP, employees may contribute between 1% and 10% of base compensation, after-tax, to purchase up to $25,000 of CSX common stock per year at 85% of the closing market price on either the grant date or the last day of the six-month offering period, whichever is lower. During the quarter ended March 31, 2019, 105 thousand shares of CSX stock were issued at a weighted average purchase price of $52.81 per share. These issuances were related to employee contributions in 2018.

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

| March 31, 2019 |  | December 31, 2018
(Dollars in millions) | Current | Long-term | Total |  | Current | Long-term | Total
Casualty: |  |  |  |  |  |  |

Total | $ | 112 |  | $ | 207 |  | $ | 319 |  |  | $ | 113 |  | $ | 211 |  | $ | 324 |

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
Casualty reserves of $195 million and $199 million as of March 31, 2019 and December 31, 2018, respectively, represent accruals for personal injury, occupational disease and occupational injury claims. During second quarter 2018, the Company increased its self-insured retention amount for these claims from $50 million to $75 million per occurrence for claims occurring on or after June 1, 2018. Currently, no individual claim is expected to exceed the self-insured retention amount. In accordance with the Contingencies Topic in the ASC, to the extent the value of an individual claim exceeds the self-insured retention amount, the Company would present the liability on a gross basis with a corresponding receivable for insurance recoveries. These reserves fluctuate based upon the timing of payments as well as changes in estimate. Actual results may vary from estimates due to the number, type and severity of the injury, costs of medical treatments and uncertainties in litigation. Most of the Company's casualty claims relate to CSXT. 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.

NOTE 4. Casualty, Environmental and Other Reserves, continued
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 for the quarter resulted in an immaterial adjustment to the personal injury reserve. The 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.
Occupational
Occupational reserves represent liabilities for occupational disease and injury claims. Occupational disease claims arise primarily from allegations of exposure to asbestos in the workplace. Occupational injury claims arise from allegations of exposure to certain other materials in the workplace, such as solvents, soaps, chemicals (collectively referred to as “irritants”) and diesel fuels (like exhaust fumes) or allegations of chronic physical injuries resulting from work conditions, such as repetitive stress injuries.
Environmental
Environmental reserves were $80 million as of each March 31, 2019 and December 31, 2018. 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 226 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.

NOTE 4. Casualty, Environmental and Other Reserves, continued
In accordance with the Asset Retirement and Environmental Obligations Topic in the ASC, the Company reviews its role with respect to each site identified at least quarterly, giving consideration to a number of factors such as:

• | type of clean-up required;

• | nature of the Company's alleged connection to the location (e.g., generator of waste sent to the site or owner or operator of the site);

• | extent of the Company's alleged connection (e.g., volume of waste sent to the location and other relevant factors); and

• | number, connection and financial viability of other named and unnamed potentially responsible parties at the location.

Based on the review process, the Company has recorded amounts to cover contingent anticipated future environmental remediation costs with respect to each site to the extent such costs are reasonably estimable and probable. The recorded liabilities for estimated future environmental costs are undiscounted. The liability includes future costs for remediation and restoration of sites as well as any significant ongoing
monitoring costs, but excludes any anticipated insurance recoveries. Payments related to these liabilities are expected to be made over the next several years. Environmental remediation costs are included in materials, supplies and other on the consolidated income statements.
Currently, the Company does not possess sufficient information to reasonably estimate the amounts of additional liabilities, if any, on some sites until completion of future environmental studies. In addition, conditions that are currently unknown could, at any given location, result in additional exposure, the amount and materiality of which cannot presently be reasonably estimated. Based upon information currently available, however, the Company believes its environmental reserves accurately reflect the estimated cost of remedial actions currently required.
Other
Other reserves of $44 million and $45 million as of March 31, 2019 and December 31, 2018, respectively. These reserves include liabilities for various claims, such as property, automobile and general liability. Also included in other reserves are longshoremen disability claims related to a previously owned international shipping business (these claims are in runoff) as well as claims for current port employees.

NOTE 5. Leases
CSX has various lease agreements with terms up to 50 years, including leases of land, land with integral equipment (e.g. track), buildings and various equipment. Some leases include options to purchase, terminate or extend for one or more years. These options are included in the lease term when it is reasonably certain that the option will be exercised.
At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of the Company’s lease arrangements contain lease components (e.g. minimum rent payments) and non-lease components (e.g. maintenance, labor charges, etc.). The Company generally accounts for each component separately based on the estimated standalone price of each component. For certain equipment leases, such as freight car, vehicles and work equipment, the Company accounts for the lease and non-lease components as a single lease component.
Certain of the Company’s lease agreements include rental payments that are adjusted periodically for an index or rate. The leases are initially measured using the projected payments adjusted for the index or rate in effect at the commencement date. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Operating Leases
Operating leases are included in right-of-use lease assets, other current liabilities and long-term lease liabilities on the consolidated balance sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term using the Company’s secured incremental borrowing rates or implicit rates, when readily determinable. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet.
Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease expense is recognized in the period in which the obligation for those payments is incurred. Lease expense is included in equipment and other rents on the consolidated income statements and is reported net of lease income. Lease income is not material to the results of operations for the quarter ended March 2019.

Cash Flows
An initial right-of-use asset of $534 million was recognized as a non-cash asset addition with the adoption of the new lease accounting standard. Additional right-of-use assets of $30 million were recognized as non-cash asset additions that resulted from new operating lease liabilities during first quarter 2019. Cash paid for amounts included in the present value of operating lease liabilities was $14 million during first quarter 2019 and is included in operating cash flows.
Operating Lease Costs
Operating lease costs were $18 million during first quarter 2019. These costs are primarily related to long-term operating leases, but also include immaterial amounts for variable leases and short-term leases with terms greater than 30 days.
Finance Leases
Finance leases are included in properties - net and long-term debt on the consolidated balance sheets. The associated amortization expense and interest expense are included in depreciation and interest expense, respectively, on the consolidated income statements. These leases are not material to the consolidated financial statements as of March 31, 2019.

NOTE 6. Commitments and Contingencies
Insurance
The Company maintains insurance programs with substantial limits for property damage (which includes business interruption) and third-party liability. A certain amount of risk is retained by the Company on each of the property and liability programs. The Company has a $50 million per occurrence retention for floods and named windstorms and a $25 million per occurrence retention for property losses other than floods and named windstorms. For claims occurring on or after June 1, 2018, the Company increased its self-insured retention for third-party liability claims from $50 million to $75 million per occurrence. 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 reasonably determined, 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 $4 million to $102 million in aggregate at March 31, 2019. 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. In November 2007, the class action lawsuits were consolidated in federal court in the District of Columbia, where they are now pending. The suit seeks treble damages allegedly sustained by purported class members as well as attorneys' fees and other relief. Plaintiffs are expected to allege damages at least equal to the fuel surcharges at issue.

NOTE 6. Commitments and Contingencies, continued
In June 2012, the District Court certified the case as a class action. The decision was not a ruling on the merits of plaintiffs' claims, but rather a decision to allow the plaintiffs to seek to prove the case as a class. The defendant railroads petitioned the U.S. Court of Appeals for the D.C. Circuit for permission to appeal the District Court's class certification decision. In August 2013, the D.C. Circuit issued a decision vacating the class certification decision and remanded the case to the District Court to reconsider its class certification decision. On October 10, 2017, the District Court issued an order denying class certification. The U.S. Court of Appeals for the D.C. Circuit is reviewing the District Court's denial of class certification and held oral argument on September 28, 2018, with a decision yet to be issued. The District Court has delayed proceedings on the merits of the case pending the outcome of the class certification proceedings.
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 this matter or an unexpected adverse decision on the merits could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.
Environmental
CSXT is indemnifying Pharmacia LLC (formerly known as Monsanto Company) 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 cleanup and removal costs and other damages associated with the presence 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.
In March 2016, EPA issued its Record of Decision detailing the agency’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 process to assign responsibility for costs to be incurred implementing the remedy selected for the lower 8 miles of the Study Area. CSXT is participating in the allocation 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’s CERCLA authority to compel such participation, if necessary.
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.

NOTE 7. Employee Benefit Plans
The Company sponsors defined benefit pension plans principally for salaried, management personnel. CSX also sponsors a non-contributory post-retirement medical plan and a life insurance plan that provide certain benefits to eligible employees hired prior to January 1, 2003. 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.

Debt Issuance
On February 28, 2019, CSX issued $600 million of 4.25% notes due 2029, which was a reopening of existing notes originally issued in November 2018, and $400 million of 4.50% notes due 2049. These notes are included in the consolidated balance sheets under long-term debt and may be redeemed by the Company at any time, subject to payment of certain make-whole premiums. The net proceeds will be used for general corporate purposes, which may include repurchases of CSX's common stock, capital investment, working capital requirements, improvements in productivity and other cost reduction initiatives at the Company’s major transportation units.
Credit Facility
On March 29, 2019, CSX replaced its existing $1.0 billion unsecured, revolving credit facility with a new $1.2 billion unsecured, revolving credit facility backed by a diverse syndicate of banks. The new facility allows same-day borrowings at floating interest rates, based on LIBOR or an agreed-upon replacement, plus a spread that depends upon 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, 2019, 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 2019, CSX was in compliance with all covenant requirements under this facility.
Commercial Paper
In September 2018, the Company established 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. Proceeds from issuances of the notes are expected to be used for general corporate purposes. At March 31, 2019, the Company had no outstanding debt under the commercial paper program.

NOTE 9. Revenues
The Company’s revenues are primarily derived from the transportation of freight as performance obligations that arise from its contracts with customers are satisfied. The following table presents the Company’s revenues disaggregated by lines of business as this best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors:

Other | 168 |  | 145 |
Total | $ | 3,013 |  | $ | 2,876 |

Revenue Recognition
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’s performance obligation arises when it receives a bill of lading (“BOL”) to transport a customer's commodities at a negotiated price contained in a transportation services agreement or a publicly disclosed tariff rate. Once a BOL is received, a contract is formed whereby the parties are committed to perform, collectability of consideration is probable and the rights of the parties, shipping terms and conditions, and payment terms are identified. A customer may submit several BOLs for transportation services at various times throughout a service agreement term but each shipment represents a distinct service that is a separately identified performance obligation.
The average transit time to complete a shipment is between 3 to 8 days and 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.

NOTE 9. Revenues, continued
The certain key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:

• | Revenue associated with shipments in transit is recognized ratably over transit time and is based on average cycle times to move commodities and products from their origin to their final destination or interchange;

• | Adjustments to revenue for billing corrections and billing discounts;

• | Adjustments to revenue for overcharge claims filed by customers, which are based on historical payments to customers for rate overcharges as a percentage of total billing; and

• | Incentive-based refunds to customers, which are primarily volume-related, are recorded as a reduction to revenue on the basis of the projected liability (this estimate is based on historical activity, current volume levels and forecasted future volume).

Revenue related to interline transportation services that involve the services of another party, such as another railroad, is reported on a net basis. The portion of the gross amount billed to customers that is remitted by the Company to another party is not reflected as revenue.
Other revenue is comprised of revenue from regional subsidiary railroads and incidental charges, including demurrage and switching. It is recorded upon completion of the service and accounted for 6% of the Company’s total revenue in the first quarter 2019. 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 revenue is primarily generated when the Company switches cars for a customer or another railroad.
During the first quarters 2019 and 2018, revenue recognized from performance obligations related to prior periods (for example, due to changes in transaction price), was not material.
Remaining Performance Obligations
Remaining performance obligations represent the transaction price allocated to future reporting periods for freight services started but not completed at the reporting date. This includes the unearned portion of billed and unbilled amounts for cancellable freight shipments in transit. The Company expects to recognize the unearned portion of revenue for freight services in transit within one week of the reporting date. As of March 31, 2019, the Company had no material remaining performance obligations.
Contract Balances and Accounts Receivable
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. The Company had no material contract assets, contract liabilities or deferred contract costs recorded on the consolidated balance sheet as of March 31, 2019.

The Company maintains an allowance for doubtful accounts to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables and economic conditions. Impairment losses recognized on the Company’s accounts receivable were no t material in the first quarters 2019 and 2018.

NOTE 11. Fair Value Measurements
The Financial Instruments Topic in the ASC requires disclosures about fair value of financial instruments in annual reports as well as in quarterly reports. For CSX, this statement applies to certain investments and long-term debt. Disclosure of the fair value of pension plan assets is only required annually. Also, this rule clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements.
Various inputs are considered when determining the value of the Company's investments, pension plan assets and long-term debt. The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in these securities. These inputs are summarized in the three broad levels listed below.

• | Level 1 - observable market inputs that are unadjusted quoted prices for identical assets or liabilities in active markets;

• | Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, credit risk, etc.); and

• | Level 3 - significant unobservable inputs (including the Company's own assumptions about the assumptions market participants would use in determining the fair value of investments).

The valuation methods described below may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
Investments
The Company's investment assets, valued with assistance from a third-party trustee, consist of certificates of deposits, commercial paper, corporate bonds and government securities and are carried at fair value on the consolidated balance sheet per the Fair Value Measurements and Disclosures Topic in the ASC. There are several valuation methodologies used for those assets as described below.

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

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

The Company's investment assets are carried at fair value on the consolidated balance sheets as summarized in the following table. All of the inputs used to determine the fair value of the Company's investments are Level 2 inputs. The amortized cost basis of these investments was $903 million and $340 million as of March 31, 2019 and December 31, 2018, respectively.

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 majority of the Company's long-term debt is valued with assistance from an independent third party adviser that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the independent adviser, 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 independent adviser. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.
The fair value of outstanding debt fluctuates with changes in a number of factors. Such factors include, but are not limited to, interest rates, market conditions, credit ratings, values of similar financial 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. Under current accounting rules, the fair value of debt does not impact the financial statements. The fair value and carrying value of the Company's long-term debt is as follows:

(Dollars in millions) | March 31, 2019 |  | December 31, 2018
Long-term Debt (Including Current Maturities): |  |  |

NOTE 12. Other Comprehensive Income (Loss)
CSX reports comprehensive earnings or loss in accordance with the Comprehensive Income Topic in the ASC in the Consolidated Comprehensive Income Statement. 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. Total comprehensive earnings represent the activity for a period net of tax and were $836 million and $596 million for first quarters 2019 and 2018, respectively.
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 (“AOCI”) 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 and CSX's share of AOCI of equity method investees.
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 7, Employee Benefit Plans, 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 equity earnings of affiliates on the consolidated income statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
First Quarter 2019
Revenue
Total revenue increased 5 percent for first quarter 2019 when compared to first quarter 2018 due to price increases, favorable mix, higher other revenue and increases in fuel recovery.
Merchandise
Chemicals - Volume increased as stronger waste, core chemicals and energy shipments more than offset reduced natural gas liquids, fly ash, and sand shipments.
Automotive - Volume increased due to higher shipments of trucks and SUVs.
Agricultural and Food Products - Volume increased due to gains in both the domestic and export grain markets, as well as gains in the ethanol market.
Forest Products - Volume increased due to higher export demand for wood pulp and other fiber products as well as stronger building products shipments.
Minerals - Volume increased due to stronger shipments for construction and paving projects.
Metals and Equipment - Volumes were flat as metals shipments increased due to higher domestic steel production while project-based equipment and pipe moves declined.
Fertilizers - Volume declined as winter weather conditions delayed spring fertilizer applications.
Coal
Domestic coke, iron ore and other volume increased primarily driven by higher domestic steel production. Domestic utility coal volume declined slightly reflecting continued strong competition from natural gas. Export volume declined slightly as lower metallurgical coal shipments were partially offset by higher thermal coal exports.
Intermodal
Domestic volume declined as rationalization of low-density lanes more than offset growth with existing customers. International volume increased driven by strong performance with existing customers and new service offerings to inland ports, which more than offset losses from the rationalization of low-density lanes.
Other Revenue
Other revenue increased $23 million versus prior year primarily due to a contract settlement with a customer and higher incidental charges, partially offset by payments in the prior year from customers that did not meet volume commitments.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Expenses
Expenses of $1.8 billion decreased $38 million, or 2 percent year over year, primarily driven by labor efficiencies partially offset by inflation.
Labor and Fringe expense decreased $24 million primarily due to the following:

• | Lower headcount and crew starts drove a $22 million reduction in expense.

• | Other costs decreased primarily due to the recognition of railroad retirement tax refunds related to past relocation benefits and were mostly offset by inflation.

Materials, Supplies and Other expense decreased $4 million due to the following:

• | Volume-related savings resulted from intermodal lane rationalizations.

• | Other costs increased as a result of a prior year favorable personal injury adjustment, inflation and other non-significant items.

• | Real estate gains were $27 million in 2019 compared to $32 million in 2018.

Depreciation expense increased $7 million primarily due to a larger asset base.
Fuel expense decreased $22 million primarily due to a 5 percent price decrease and cost savings from fuel efficiency initiatives.
Equipment and Other Rents expense decreased $1 million primarily due to reduced days per load for automotive, other merchandise and intermodal markets, mostly offset by automotive volume-related costs and inflation.
Equity Earnings of Affiliates decreased $6 million primarily due to lower net earnings at TTX and Conrail.
Interest Expense
Interest expense increased $29 million primarily due to higher average debt balances.
Other Income - Net
Other income - net increased $6 million primarily due to increased interest income as a result of higher average investment balances.
Income Tax Expense
Income tax expense increased $13 million primarily due to increased earnings before income taxes, partially offset by a $32 million tax benefit primarily due to impacts from option exercises and the vesting of other equity awards.

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.
Adjusted 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 certain other investing activities, which includes proceeds from property dispositions. Adjusted free cash flow excludes the impact of cash payments for restructuring charge. Free cash flow and adjusted free cash flow should be considered in addition to, rather than a substitute for, cash provided by operating activities. The increase in adjusted free cash flow before dividends from the prior year of $215 million is primarily due to higher cash-generating income, favorable changes in working capital and lower property additions.
The following table reconciles cash provided by operating activities (GAAP measure) to adjusted free cash flow after restructuring, before dividends (non-GAAP measure). The restructuring charge impact to free cash flow in 2018 was tax effected using the Company's applicable tax rate.

| Three Months

Adjusted Free Cash Flow Before Dividends (non-GAAP) | $ | 866 |  | $ | 651 |

(a) The Company made cash payments related to the restructuring charge of $12 million in first quarter 2018.
Operating Statistics (Estimated)
The Company strives for continuous improvement in safety and service performance through training, innovation and investment. Investment in training and technology also is designed to allow the Company's employees to have an additional layer of protection that can detect and avoid many types of human factor incidents. Safety programs are designed to prevent incidents that can adversely impact employees, customers and communities. Continued capital investment in the Company's assets, including track, bridges, signals, equipment and detection technology also supports safety performance.
The methodologies used to calculate train velocity and terminal dwell are consistent with the principles of scheduled railroading, but differ from those prescribed by the Surface Transportation Board ("STB"). Train velocity and dwell will continue to be reported, using the prescribed methodology, to the STB on a weekly basis.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Operating performance continued to improve in first quarter 2019, as train velocity and car dwell improved 17 percent and 14 percent, respectively, to all-time record levels. The Company remains focused on executing the operational plan to deliver further service gains, improve transit times and drive asset utilization while controlling costs.
From a safety perspective, the FRA reportable personal injury frequency index of 0.79 for the first quarter 2019 improved 32 percent year over year, driven by a reduction in the number of personal injuries. Similarly, the FRA train accident frequency rate of 2.60 for the quarter improved 35 percent year over year, driven by a significant reduction in train accidents. This improvement continues the positive momentum CSX achieved in the latter half of 2018.
The Company is committed to continuous safety improvement and remains focused on reducing risk and enhancing the overall safety of its employees, customers and the communities in which the Company operates.

(a) The methodology for calculating train velocity and dwell differ from that prescribed by the STB. CSXT will continue to report train velocity and dwell, using the prescribed methodology, to the STB on a weekly basis. See additional discussion on the Company's website.
Certain operating statistics are estimated and can continue to be updated as actuals settle.
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.
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.
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.
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 components of the net increases of $330 million and $1.6 billion in cash and cash equivalents for operating, investing and financing activities for three months ended 2019 and 2018, respectively.

• | Cash provided by operating activities increased $207 million primarily driven by higher cash-generating income and favorable changes to working capital.

• | Cash used in investing activities increased $554 million primarily driven by an increase in net short-term investment purchases.

• | Cash used in financing activities decreased $902 million primarily due to lower long-term debt issuances versus the prior year.

Sources of Cash and Liquidity and Uses of Cash
As of the end of first quarter 2019, CSX had $2.0 billion of cash, cash equivalents and short-term investments. CSX uses current cash balances for general corporate purposes, which may include reduction or refinancing of outstanding indebtedness, capital expenditures, working capital requirements, contributions to the Company's qualified pension plan, redemptions and repurchases of CSX common stock and dividends to shareholders. See Note 8, 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 12, 2019, which is unlimited as to amount and may be used to issue debt or equity securities at CSX’s discretion, subject to market conditions and CSX Board authorization. While CSX seeks to give itself flexibility with respect to cash requirements, there can be no assurance that market conditions would permit CSX to sell such securities on acceptable terms at any given time, or at all. In first quarter 2019, CSX issued a total of $1.0 billion of new long-term debt.

| CSX Q1 2019 Form 10-Q p.39 |

Table of Contents
CSX CORPORATION
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
On March 29, 2019, CSX replaced its existing $1.0 billion unsecured, revolving credit facility with a new $1.2 billion unsecured, revolving credit facility backed by a diverse syndicate of banks. The new facility expires in March 2024 and at March 31, 2019, 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, 2019, the Company had no outstanding debt under the commercial paper program.
Planned capital investments for 2019 are expected to be between $1.6 billion and $1.7 billion, including approximately $100 million for Positive Train Control ("PTC"). Of the 2019 investment, over half will be used to sustain the core infrastructure. The remaining amounts will be allocated to projects supporting service enhancements, productivity initiatives and profitable growth. CSX intends to fund capital investments through cash generated from operations.
The Company expects to continue incurring capital costs in connection with the implementation of PTC. CSX estimates that the total multi-year cost of PTC implementation will be approximately $2.4 billion. This estimate includes costs for installing the new system along tracks, upgrading locomotives, adding communication equipment and developing new technologies. Total PTC spending through March 2019 was $2.3 billion.
Material Changes in the Consolidated Balance Sheets and Working Capital
Consolidated Balance Sheets
Total assets increased $1.4 billion from year end primarily due to the net increase in cash and short-term investments of $899 million and the right-of-use lease asset of $550 million resulting from the adoption of the new lease accounting standard. The increase in cash and short-term investments was primarily the result of cash from operations of $1.2 billion and the issuance of $1.0 billion in long-term debt, partially offset by share repurchases of $796 million, property additions of $353 million and dividends paid of $195 million.
Total liabilities and shareholders' equity combined increased $1.4 billion from year end primarily due to the issuance of $1.0 billion in long-term debt, net earnings of $834 million and the total lease liability of $555 million resulting from the adoption of the new lease accounting standard. These increases were partially offset by share repurchases of $796 million and dividends paid of $195 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 $1.6 billion and $650 million as of March 31, 2019 and December 31, 2018, respectively. The increase in working capital since year end of $903 million is primarily due to the increase in cash and short-term investments. The increase in cash was driven by cash from operations of $1.2 billion and proceeds from the $1.0 billion issuance of long-term debt, partially offset by share repurchases of $796 million, property additions of $353 million and dividend payments of $195 million.
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.

CSX CORPORATION
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.
LABOR AGREEMENTS
All 13 rail unions that participate in national bargaining have reached national agreements with the Class I railroads via ratification, executive action or interest arbitration. These agreements are effective January 1, 2015 through December 31, 2019.
CRITICAL ACCOUNTING ESTIMATES
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates in reporting the amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and certain revenues and expenses during the reporting period. Actual results may differ from those estimates. These estimates and assumptions are discussed with the Audit Committee of the Board of Directors on a regular basis. Consistent with the prior year, significant estimates using management judgment are made for the areas below. For further discussion of CSX's critical accounting estimates, see the Company's most recent annual report on Form 10-K.

• | personal injury, environmental and legal reserves;

• | pension and post-retirement medical plan accounting;

• | depreciation policies for assets under the group-life method; and

• | income taxes.

PART II
Item 2. CSX Purchases of Equity Securities
CSX purchases its own shares for two primary reasons: (1) to further its goals under its share repurchase program and (2) to fund the Company’s contribution required to be paid in CSX common stock under a 401(k) plan that covers certain union employees.
In February 2018, the Company announced an increase to the $1.5 billion share repurchase program first announced in October 2017, bringing the total authorized to $5 billion. This program was completed on January 16, 2019. Also on January 16, 2019, the Company announced a new $5 billion share repurchase program. During the first quarters of 2019 and 2018, the Company repurchased approximately $796 million, or 12 million shares, and $836 million, or 15 million shares, respectively.
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. Share repurchase activity for the first quarter 2019 was as follows:

| CSX Purchases of Equity Securities for the Quarter |
Third Quarter | Total Number of Shares Purchased | Average Price Paid per Share | Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs (a) | Approximate Dollar Value of Shares that May Yet Be Purchased Under the Plans or Programs
Beginning Balance |  |  |  | $ | 129,128,793 |
January 1 - January 31, 2019 | 3,758,673 |  | $ | 64.19 |  | 3,650,748 |  | 4,895,001,377 |
February 1 - February 28, 2019 | 4,078,567 |  | 69.88 |  | 4,078,567 |  | 4,610,002,040 |
March 1 - March 31, 2019 | 3,810,493 |  | 72.78 |  | 3,810,298 |  | 4,332,672,444 |
Ending Balance | 11,647,733 |  | $ | 68.99 |  | 11,539,613 |  | $ | 4,332,672,444 |

(a) The difference of 108,120 shares between the "Total Number of Shares Purchased" and the "Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs" for the quarter represents shares purchased to fund the Company's contribution to a 401(k) plan that covers certain union employees.
