Condensed Consolidated Statement of Changes in Common Shareholders’ Equity (Unaudited)

The accompanying notes are an integral part of these unaudited Condensed Consolidated Financial Statements.

For purposes of this report, unless the context otherwise requires, all references herein to the “Corporation”, “UPC”, “we”, “us”, and “our” mean Union Pacific Corporation and its subsidiaries, including Union Pacific Railroad Company, which will be separately referred to herein as “UPRR” or the “Railroad”.

1. Responsibilities for Financial Statements – Our Condensed Consolidated Financial Statements are unaudited and reflect all adjustments (consisting only of normal and recurring adjustments) that are, in the opinion of management, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America. Our Consolidated Statement of Financial Position at December 31, 2006, is derived from audited financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with our Consolidated Financial Statements and notes thereto contained in our 2006 Annual Report on Form 10-K. The results of operations for the three and nine months ended September 30, 2007, are not necessarily indicative of the results for the entire year ending December 31, 2007.

2. Stock-Based Compensation – We have several stock-based compensation plans under which employees and non-employee directors receive stock options, nonvested retention shares, and nonvested stock units. We refer to the nonvested shares and stock units collectively as “retention awards”. We issue treasury shares to cover option exercises and stock unit vestings, while new shares are issued when retention shares vest. We measure and recognize compensation expense following Financial Accounting Standards Board (FASB) Statement No. 123(R), Share-Based Payment. Expense is measured on the grant date and is expensed ratably over the service period of the awards (generally the vesting period). Information regarding stock-based compensation appears in the table below:

Stock Options – We estimate the fair value of our stock option awards using the Black-Scholes option pricing model. Groups of employees and non-employee directors that have similar historical and expected exercise behavior are considered separately for valuation purposes. The table below shows the year-to-date weighted-average assumptions used for valuation purposes:

The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant; the dividend yield is calculated as the ratio of dividends paid per share of common stock to the stock price on the date of grant; the expected life is based on historical and expected exercise behavior; and volatility is based on the historical volatility of our stock price over the expected life of the option.

A summary of stock option activity during the nine months ended September 30, 2007 is presented below:

Stock options are granted at the closing price on the date of grant, have ten-year contractual terms, and vest no later than three years from the date of grant. None of the stock options outstanding at September 30, 2007 are subject to performance or market-based vesting conditions.

At September 30, 2007, there was $31 million of unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted-average period of 1.5 years. Additional information regarding stock option exercises appears in the table below:

Retention Awards – The fair value of retention awards is based on the closing price of the stock at the grant date. Dividend equivalents are paid to participants during the vesting periods.

Changes in our retention awards during the nine months ended September 30, 2007 were as follows:

Retention awards are granted at no cost to the employee or non-employee director and vest over periods lasting up to four years. At September 30, 2007, there was $43 million of total unrecognized compensation expense related to nonvested retention awards, which is expected to be recognized over a weighted-average period of 2.3 years.

Performance Retention Awards – In January 2007, our Board of Directors approved performance stock unit grants. Other than raising the performance targets, the basic terms of these performance stock units are identical to those granted in January 2006, including annual return on invested capital (ROIC) as the performance measure. Stock units awarded to selected employees under these grants are subject to continued employment for 37 months and the attainment of certain levels of ROIC. We will expense the fair value of the units that are probable of being earned based on our forecasted ROIC over the 3-year performance period. We measure the fair value of these performance stock units based upon the closing price of the underlying common stock as of the date of grant,

reduced by the present value of estimated future dividends. Dividend equivalents are paid to participants only after the units are earned.

The assumptions used to calculate the present value of estimated future dividends are as follows:

Changes in our performance retention awards during the nine months ended September 30, 2007 were as follows:

At September 30, 2007, there was $17 million of total unrecognized compensation expense related to nonvested performance retention awards, which is expected to be recognized over a weighted-average period of 1.9 years. A portion of this expense is subject to achievement of the ROIC levels established for the performance stock unit grants.

3. Operations and Segmentation – The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment. Although revenue is analyzed by commodity group, we analyze the net financial results of the Railroad as one segment due to the integrated nature of our rail network.

Strategy and Risk – We may use derivative financial instruments in limited instances for other than trading purposes to assist in managing our overall exposure to fluctuations in interest rates and fuel prices. We are not a party to leveraged derivatives and, by policy, do not use derivative financial instruments for speculative purposes. Derivative financial instruments qualifying for hedge accounting must maintain a specified level of effectiveness between the hedging instrument and the item being hedged, both at inception and throughout the hedged period. We formally document the nature and relationships between the hedging instruments and hedged items, as well as our risk-management objectives, strategies for undertaking the various hedge transactions, and method of assessing hedge effectiveness. Changes in the fair market value of derivative financial instruments that do not qualify for hedge accounting are charged to earnings. We may use swaps, collars, futures, and/or forward contracts to mitigate the risk of adverse movements in interest rates and fuel prices; however, the use of these derivative financial instruments may limit future benefits from favorable price movements.

Market and Credit Risk – We address market risk related to derivative financial instruments by selecting instruments with value fluctuations that highly correlate with the underlying hedged item. Credit risk related to derivative financial instruments, which is minimal, is managed by requiring high credit standards for counterparties and periodic settlements. At September 30, 2007 and December 31, 2006, we were not required to provide collateral, nor had we received collateral, relating to our hedging activities.

Determination of Fair Value – We determine the fair values of our derivative financial instrument positions based upon current fair values as quoted by recognized dealers or the present value of expected future cash flows.

Interest Rate Fair Value Hedges – We manage our overall exposure to fluctuations in interest rates by adjusting the proportion of fixed and floating rate debt instruments within our debt portfolio over a given period. We generally manage the mix of fixed and floating rate debt through the issuance of targeted amounts of each as debt matures or as we require incremental borrowings. We employ derivatives, primarily swaps, as one of the tools to obtain the targeted mix. In addition, we also obtain flexibility in managing interest costs and the interest rate mix within our debt portfolio by evaluating the issuance of and managing outstanding callable fixed-rate debt securities.

Swaps allow us to convert debt from fixed rates to variable rates and thereby hedge the risk of changes in the debt’s fair value attributable to the changes in interest rates. We account for swaps as fair value hedges using the short-cut method pursuant to FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities; therefore, we do not record any ineffectiveness within our Condensed Consolidated Financial Statements.

The following is a summary of our interest rate derivatives qualifying as fair value hedges:

Interest Rate Cash Flow Hedges – We report changes in the fair value of cash flow hedges in accumulated other comprehensive loss until the hedged item affects earnings. At both September 30, 2007 and December 31, 2006, we had a reduction of $5 million recorded as an accumulated other comprehensive loss that is being amortized on a straight-line basis through September 30, 2014. As of September 30, 2007 and December 31, 2006, we had no interest rate cash flow hedges outstanding.

Fuel Swaps – We have two fuel basis swaps that expire in July 2008. These commodity basis swaps require us to make payments to, or receive payments from, the counterparty based on the difference between certain price indices. Changes in the fair value of these swaps are reflected in fuel expense.

Earnings Impact – Our use of derivative financial instruments had the following impact on pre-tax income:

Sale of Receivables – The Railroad transfers most of its accounts receivable to Union Pacific Receivables, Inc. (UPRI), a bankruptcy-remote subsidiary, as part of a sale of receivables facility. UPRI sells to investors, without recourse on a 364-day revolving basis, an undivided interest in such accounts receivable. The total capacity to sell undivided interests to investors under the facility was $600 million at both September 30, 2007 and December 31, 2006. The value of the outstanding undivided interest held by investors under the facility was $600 million at both September 30, 2007 and December 31, 2006, respectively. The value of the outstanding undivided interest held by investors is not included in our Condensed Consolidated Financial Statements. The value of the undivided interest held by investors was supported by $1,270 million and $1,158 million of accounts receivable held by UPRI at September 30, 2007 and December 31, 2006, respectively. At September 30, 2007 and December 31, 2006, the value of the interest retained by UPRI was $670 million and $558 million, respectively. This retained interest is included in accounts receivable in our Condensed Consolidated Financial Statements. The interest sold to investors is sold at carrying value, which approximates fair value, and there is no gain or loss recognized from the transaction.

The value of the outstanding undivided interest held by investors could fluctuate based upon the availability of eligible receivables and is directly affected by changing business volumes and credit risks, including default and dilution. If default or dilution percentages were to increase one percentage point, the amount of eligible receivables would decrease by $6 million. Should our credit rating fall below investment grade, the value of the outstanding undivided interest held by investors would be reduced, and, in certain cases, the investors would have the right to discontinue the facility.

The Railroad services the sold receivables; however, the Railroad does not recognize any servicing asset or liability as the servicing fees adequately compensate the Railroad for its responsibilities. The Railroad collected approximately $12 billion and $11 billion during the nine months ended September 30, 2007 and 2006, respectively. UPRI used certain of these proceeds to purchase new receivables under the facility.

The costs of the sale of receivables program are included in other income and were $9 million for both the three months ended September 30, 2007 and 2006, and $26 million and $25 million for the nine months ended September 30, 2007 and 2006, respectively. The costs include interest, program fees paid to banks, commercial paper issuing costs, and fees for unused commitment availability.

The investors have no recourse to the Railroad’s other assets except for customary warranty and indemnity claims. Creditors of the Railroad have no recourse to the assets of UPRI. In August 2007, the sale of receivables program was renewed for an additional 364-day period without any significant changes in terms.

Credit Facilities – On September 30, 2007, we had $1.9 billion of credit available under our new revolving credit facility (the “facility”), which we entered into on April 20, 2007. The facility is designated for general corporate purposes and supports the issuance of commercial paper. The facility was not drawn on as of September 30, 2007. Commitment fees and interest rates payable under the facility are similar to fees and rates available to comparably rated investment-grade borrowers. The facility allows for borrowings at floating rates based on London Interbank Offered Rates, plus a spread, depending upon our senior unsecured debt ratings. The facility requires the maintenance of a debt to net worth coverage ratio. At September 30, 2007, we were in compliance with this covenant. The facility does not include any other financial restrictions, credit rating triggers (other than rating-dependent pricing), or any other provision that could require the posting of collateral. The facility, which expires in April 2012, replaced two $1 billion 5-year facilities with terms ending in March 2009 and March 2010, respectively. The facility includes terms that are comparable with those of the prior facilities, although the minimum net worth requirement of $7.5 billion in prior facilities was removed, and the facility includes a change-of-control provision.

In addition to our revolving credit facility, we had a $75 million uncommitted line of credit available. The line of credit expires in April 2008, and was not used as of September 30, 2007. We must have equivalent credit available under our five-year facility to draw on this $75 million line.

At September 30, 2007, approximately $948 million of debt due within one year that we intend to refinance was reclassified as long-term debt. This reclassification reflected our ability and intent to refinance any short-term borrowings and certain current maturities of long-term debt on a long-term basis. At December 31, 2006, we did not reclassify any short-term debt as long-term debt as we did not intend to refinance at that time.

Dividend Restriction – We have a restriction related to the payment of cash dividends to our shareholders due to a debt to net worth covenant requirement under our current revolving credit facility. This facility, entered into on April 20, 2007, no longer has a minimum net worth covenant that was included in our previous facilities, which was more restrictive with respect to the amount of retained earnings available for dividends at December 31, 2006. The amount of retained earnings available for dividends was $11.2 billion and $7.8 billion at September 30, 2007 and December 31, 2006, respectively.

Shelf Registration Statement and Significant New Borrowings – Our Board of Directors authorized the issuance of up to $3 billion of debt securities pursuant to a new shelf registration statement, which became effective on March 6, 2007, replacing the $500 million of authority remaining under our shelf registration filed in December 2003. Under the current shelf registration, we may issue, from time to time, any combination of debt securities, preferred stock, common stock, or warrants for debt securities or preferred stock in one or more offerings.

On April 18, 2007, we issued a total of $500 million of unsecured fixed-rate debt under our current shelf registration statement. We issued $250 million of notes at 5.65%, which are due May 1, 2017, and $250 million of debentures at 6.15%, which are due May 1, 2037. In addition, on August 24, 2007, we issued $500 million of unsecured fixed-rate notes at 5.45%, which are due January 31, 2013. The net proceeds from these offerings are for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities include change-of-control provisions. We have no immediate plans to issue equity securities; however, we will continue to explore opportunities to replace existing debt or access capital through issuances of debt securities under our shelf registration, and, therefore, we may issue additional debt securities at any time.

Pension Plans – We provide defined benefit retirement income to eligible non-union employees through qualified and non-qualified (supplemental) pension plans. Qualified and non-qualified pension benefits are based on years of

service and the highest compensation during the latest years of employment, with specific reductions made for early retirements.

Other Postretirement Benefits (OPEB) – We provide defined contribution medical and life insurance benefits for eligible retirees. These benefits are funded as medical claims and life insurance premiums are paid.

Both pension and OPEB expense are determined based upon the annual service cost of benefits (the actuarial cost of benefits earned during a period) and the interest cost on those liabilities, less the expected return on plan assets. The expected long-term rate of return on plan assets is applied to a calculated value of plan assets that recognizes changes in fair value over a five-year period. This practice is intended to reduce year-to-year volatility in pension expense, but it can have the effect of delaying the recognition of differences between actual returns on assets and expected returns based on long-term rate of return assumptions. Differences in actual experience in relation to assumptions are not recognized in net income immediately, but are deferred and, if necessary, amortized as pension or OPEB expense.

7. Earnings Per Share – The following table provides a reconciliation between basic and diluted earnings per share:

Asserted and Unasserted Claims – Various claims and lawsuits are pending against us and certain of our subsidiaries. It is not possible at this time for us to determine fully the effect of all unasserted claims on our consolidated results of operations, financial condition, or liquidity; however, to the extent possible, where unasserted claims are considered probable and where such claims can be reasonably estimated, we have recorded a liability. We do not expect that any known lawsuits, claims, environmental costs, commitments, contingent liabilities, or guarantees will have a material adverse effect on our consolidated results of operations, financial condition, or liquidity after taking into account liabilities previously recorded for these matters.

Personal Injury – The cost of personal injuries to employees and others related to our activities is charged to expense based on estimates of the ultimate cost and number of incidents each year. We use third-party actuaries to assist us in measuring the expense and liability, including unasserted claims, on a semi-annual basis. Compensation for work-related accidents is governed by the Federal Employers’ Liability Act (FELA). Under FELA, damages are assessed based on a finding of fault through litigation or out-of-court settlements.

As a result of improvements in our safety experience, lower estimated ultimate settlement costs, and the completion of actuarial studies, we reduced personal injury expense by $30 million in the first quarter and $47 million in the third quarter of 2007. These adjustments were partially offset by adverse developments with respect to one claim. Our personal injury liability activity was as follows:

Because of the uncertainty surrounding the ultimate outcome of personal injury claims, it is reasonably possible that future costs to settle these claims may range from approximately $609 million to $678 million. We believe that the $609 million liability recorded at September 30, 2007, is the best estimate of the present value of the future settlement costs of personal injury claims.

Asbestos – We are a defendant in a number of lawsuits in which current and former employees allege exposure to asbestos. Additionally, we have received claims for asbestos exposure that have not been litigated. The claims and lawsuits (collectively referred to as “claims”) allege occupational illness resulting from exposure to asbestos-containing products. In most cases, the claimants do not have credible medical evidence of physical impairment

resulting from the alleged exposures. Additionally, most claims filed against us do not specify an amount of alleged damages. We use a third-party specialist with extensive experience in estimating resolution cost for asbestos-related claims to assist us in assessing the number and value of these unasserted claims.

In July 2007, we requested a third-party specialist to review our historical asbestos claim and resolution activity and determine the appropriateness of updating our November 2004 asbestos study. Based on the updated study, which was completed in the third quarter of 2007, and our own review of the asbestos claim and resolution activity, we decreased our asbestos-related liability for pending and future claims by $20 million at September 30, 2007.

We have insurance coverage for a portion of the costs incurred to resolve asbestos-related claims, and, we have recognized an asset for estimated insurance recoveries at September 30, 2007 and December 31, 2006. In conjunction with the asbestos study completed in the third quarter of 2007, we also analyzed our estimated insurance recoveries and recorded a reduction in the asset for estimated insurance recoveries.

We believe that our liability estimates for asbestos-related claims and the estimated insurance recoveries reflect reasonable and probable estimates. The amounts recorded for asbestos-related liabilities and related insurance recoveries were based on currently known facts. However, future events, such as the number of new claims to be filed each year, average settlement costs, and insurance coverage issues, could cause the actual costs and insurance recoveries to be higher or lower than the projected amounts. Estimates may also vary due to changes in the litigation environment, federal and state law governing compensation of asbestos claimants, and the level of payments made to claimants by other defendants.

Environmental Costs – We are subject to federal, state, and local environmental laws and regulations. We have 343 projects with which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 39 projects that are the subject of actions taken by the U.S. government, 21 of which are currently on the Superfund National Priorities List. Certain federal legislation imposes joint and several liability for the remediation of identified projects; consequently, our ultimate environmental liability may include costs relating to activities of other parties, in addition to costs relating to our own activities with each project.

When an environmental issue has been identified with respect to property owned, leased, or otherwise used in the conduct of our business, we and our consultants perform environmental assessments on the property. We expense the cost of the assessments as incurred. We accrue the cost of remediation where our obligation is probable and such costs can be reasonably estimated. We do not discount our environmental liabilities when the timing of the anticipated cash payments is not fixed or readily determinable. At September 30, 2007, approximately 15% of our environmental liability was discounted at 4.67%, while approximately 14% of our environmental liability was discounted at 5.34% at December 31, 2006. The discount rates are based on our risk-free rates with a maturity comparable to our environmental liability.

The environmental liability includes costs for remediation and restoration of sites, as well as for ongoing monitoring costs, but excludes any anticipated recoveries from third parties. Cost estimates are based on information available for each project, financial viability of other potentially responsible parties, and existing technology, laws, and regulations. We believe that we have adequately accrued for our ultimate share of costs at sites subject to joint and several liability. However, the ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties involved, site-specific cost sharing arrangements with other potentially responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs. Estimates may also vary due to changes in federal, state, and local laws governing environmental remediation. We do not expect current obligations to have a material adverse effect on our results of operations or financial condition.

Guarantees – At September 30, 2007, we were contingently liable for $466 million in guarantees. We have recorded a liability of $5 million for the fair value of these obligations as of September 30, 2007. We entered into these contingent guarantees in the normal course of business, and they include guaranteed obligations related to our headquarters building, equipment financings, and affiliated operations. The final guarantee expires in 2022. We are not aware of any existing event of default that would require us to satisfy these guarantees. We do not expect that these guarantees will have a material adverse effect on our consolidated financial condition, results of operations, or liquidity.

Indemnities – Our maximum potential exposure under indemnification arrangements, including certain tax indemnifications, can range from a specified dollar amount to an unlimited amount, depending on the nature of the transactions and the agreements. Due to uncertainty as to whether claims will be made or how they will be resolved, we cannot reasonably determine the probability of an adverse claim or reasonably estimate any adverse liability or the total maximum exposure under these indemnification arrangements. We do not have any reason to believe that we will be required to make any material payments under these indemnity provisions.

10. Share Repurchase Program – On January 30, 2007, our Board of Directors authorized the repurchase of up to 20 million shares of Union Pacific Corporation common stock through the end of 2009. The timing and volume of purchases will be guided by management’s assessment of market conditions and other pertinent facts.

During the nine months ended September 30, 2007, we repurchased approximately 10.2 million shares under this program at an aggregate purchase price of $1.2 billion. These shares were recorded in Treasury Stock at cost, which includes any applicable commissions and fees.

11. Income Taxes – In June 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109 (FIN 48). We adopted FIN 48 on January 1, 2007. Under FIN 48, tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. Unrecognized tax benefits are tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.

Upon the adoption of FIN 48, we had total liabilities for unrecognized tax benefits of $173 million. Of this amount, $7 million was recorded as a decrease to beginning retained earnings for the cumulative effect of adopting FIN 48. The remaining $166 million had been previously accrued under either FASB Statement No. 5, Accounting for Contingencies, or FASB Statement No. 109, Accounting for Income Taxes. The entire $173 million was classified as non-current in the Condensed Consolidated Statement of Financial Position.

Included in the $173 million balance at adoption were $126 million of unrecognized tax benefits that, if recognized, would reduce our effective tax rate. This $126 million included $47 million for interest and penalties, which are recognized as part of income tax expense. The remaining unrecognized tax benefits relate to tax positions for which ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility. Recognition of these tax benefits would reduce our effective tax rate only through a reduction of interest and penalties.

For all federal income tax years prior to 1995, the statute of limitations bars any additional assessments by the Internal Revenue Service (IRS). We have filed interest refund claims for years 1986 through 1994, which may be disputed by the IRS and may take several years to resolve. The IRS has completed its examinations and issued notices of deficiency for tax years 1995 through 2004, and we are in different stages of the IRS appeals process for these years. In the third quarter of 2007, we believe that we have reached an agreement in principle with the IRS to resolve all of the issues, except interest, related to tax years 1995 through 1998, including the previously reported dispute over certain donations of property. We anticipate signing a closing agreement in the fourth quarter of 2007 or the first quarter of 2008. Once formalized, we anticipate that this agreement will result in an immaterial reduction of income tax expense.

Upon resolution of the federal income tax examinations described above, we will report any changes to our taxable income to state and local taxing authorities in compliance with state and local requirements. Additionally, several state taxing authorities are currently examining our state income tax returns for tax years 1999 through 2004.

In the third quarter of 2007, the State of Illinois enacted new tax legislation that changes how we determine the amount of our income subject to Illinois tax. This legislation increased our deferred tax expense by $27 million in the third quarter. In addition, because the legislation reduced uncertainty about determining future income subject to Illinois tax, $26 million of unrecognized tax benefits have been reclassified as a deferred tax liability.

Total liabilities for unrecognized tax benefits are $131 million at September 30, 2007. Included in this balance are $105 million of unrecognized tax benefits that, if recognized, would reduce our effective tax rate. This $105 million includes $47 million for interest and penalties. Of the $131 million, $123 million is classified as current in the Condensed Consolidated Statement of Financial Position, primarily for anticipated federal and state payments to close the 1995 through 1998 tax years described above, which will reduce our unrecognized tax benefits when paid.

13. Accounting Pronouncements – In September 2006, the FASB issued Statement No. 157, Fair Value Measurement (FAS 157). While this statement does not require new fair value measurements, it provides guidance on applying fair value and expands required disclosures. FAS 157 is effective for us beginning in the first quarter of 2008. We are currently assessing the impact FAS 157 may have on our Condensed Consolidated Financial Statements.

In February 2007, the FASB issued Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (FAS 159). This statement permits entities to choose to measure many financial instruments and certain other items at fair value. FAS 159 is effective for us beginning in the first quarter of 2008. We are currently assessing the impact FAS 159 may have on our Condensed Consolidated Financial Statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

For purposes of this report, unless the context otherwise requires, all references herein to “UPC”, “Corporation”, “we”, “us”, and “our” shall mean Union Pacific Corporation and its subsidiaries, including Union Pacific Railroad Company, which we separately refer to as “UPRR” or the “Railroad”.

The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements and applicable notes to the Condensed Consolidated Financial Statements, Item 1, and other information included in this report. Our Condensed Consolidated Financial Statements are unaudited and reflect all adjustments (consisting only of normal and recurring adjustments) that are, in the opinion of management, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America (GAAP).

The Railroad, along with its subsidiaries and rail affiliates, is our one reportable business segment. Although revenue is analyzed by commodity, we analyze the net financial results of the Railroad as one segment due to the integrated nature of the rail network.

References to our website address in this report, including references in Management’s Discussion and Analysis of Financial Condition and Results of Operations, Item 2, are provided as a convenience and do not constitute, and should not be deemed, an incorporation by reference of the information contained on, or available through, the website. Therefore, such information should not be considered part of this report.

Our discussion and analysis of our financial condition and results of operations are based upon our Condensed Consolidated Financial Statements. The preparation of these financial statements requires estimation and judgment that affect the reported amounts of revenue, expenses, assets, and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. If these estimates differ materially from actual results, the impact on the Condensed Consolidated Financial Statements may be material. Our critical accounting policies are available in Item 7 of our 2006 Annual Report on Form 10-K. There have been no significant changes with respect to these policies during the first nine months of 2007, except for the treatment of tax contingency accruals.

Effective January 1, 2007, we began to measure and record tax contingency accruals in accordance with Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109 (FIN 48). Under FIN 48, we will recognize tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. Unrecognized tax benefits are tax benefits claimed in our tax returns that do not meet these recognition and measurement standards. For additional information on the adoption of FIN 48, see note 11 in Part I, Item 1 of this Quarterly Report.

We reported earnings of $2.00 per diluted share on net income of $532 million in the third quarter of 2007 compared to earnings of $1.54 per diluted share on net income of $420 million for the third quarter of 2006. Year-to-date 2007 net income was $1.4 billion versus $1.1 billion for the same period in 2006. Yield increases, network management initiatives, improved productivity, reduced workforce levels, and lower casualty costs more than offset cost increases due to inflation, resulting in a 34% and 21% improvement in operating income for the third quarter and year-to-date periods, respectively. Despite softening in some sectors of our industrial products business, volume levels grew 1% during the third quarter to a new record level. Year-to-date, adverse weather conditions and a 2% decline in shipment volume adversely affected earnings growth.

Operationally, we improved our network fluidity versus the third quarter of 2006 despite disruptions caused by severe weather in July and track maintenance, which generally is heavier during the summer months on a large portion of our network. As reported to the Association of American Railroads, terminal dwell time and average train speed improved 4% and 1%, respectively, during the third quarter of 2007 compared to the same period of 2006. Focused efforts on terminal processing initiatives and improved asset utilization drove the improvement.

Operating revenue includes commodity revenue and other revenue. The primary drivers of commodity revenue are volume (carloads) and average revenue per car (ARC). ARC varies with changes in price, commodity mix, and fuel surcharges. Other revenue primarily consists of revenue earned by our subsidiaries, revenue from our commuter rail operations, and accessorial revenue, which we earn when customers retain equipment owned or controlled by us or when we perform additional services such as switching or storage.

We recognize revenue on a percentage-of-completion basis as freight moves from origin to destination. We allocate revenue between reporting periods based on the relative transit time in each reporting period and recognize expenses as we incur them. We recognize other revenue as service is performed or contractual obligations are met. We provide incentives to our customers for meeting or exceeding specified cumulative volumes or shipping to and from specific locations, which we record as a reduction to revenue based on the actual or projected future shipments.

Revenue from five of our six commodity groups increased during the third quarter and year-to-date periods of 2007, while revenue generated from industrial products shipments declined in both periods versus 2006. ARC increased 5% during the third quarter of 2007 driven by core price improvement, partially offset by a negative change to our commodity mix. The combination of record coal carloads and an 8% decline in industrial products volume resulted in the negative quarterly mix. Year-to-date, ARC grew 6% due to core price increases. Volume was up 1% during the third quarter as growth in automotive, chemical, energy, and agricultural shipments was mostly offset by lower shipments of industrial products.

Our fuel surcharge programs (excluding index-based contract escalators that contain some provision for fuel) generated $372 million and $1.1 billion in commodity revenue in the third quarter and nine-month periods of 2007. Fuel surcharge revenue is not comparable to prior periods due to implementation of new mileage-based fuel surcharge programs. As previously disclosed in our 2006 Annual Report on Form 10-K, the Surface Transportation Board (STB) of the United States Department of Transportation issued a decision limiting the manner in which U.S. railroads can calculate fuel surcharges on traffic regulated by the STB. Effective April 26, 2007, we implemented new fuel surcharge programs covering regulated, tariff-based traffic, which represents approximately 18% of our current revenue base. The new programs use mileage as the basis to calculate fuel surcharges versus percent of revenue and correlate to movement of the On-Highway Diesel Price index, published by the Energy Information Administration. The new programs affect fuel surcharges assessed for certain shipments of agricultural, chemical, and industrial

products, and, to a lesser extent, coal. In addition, we reset the effective base fuel price at which the new fuel surcharge programs take effect, resulting in a higher entry point of $2.30 per gallon versus $1.35 per gallon.

The following tables summarize the year-over-year changes in commodity revenue, revenue carloads, and ARC by commodity type:

Agricultural Products – Price increases primarily drove higher agricultural commodity revenue in the third quarter and year-to-date periods of 2007 versus 2006. Increased shipments of wheat and food grains improved third quarter volumes as a strong wheat crop in regions served by us generated record shipments to the Gulf Coast for export. Continuing growth and demand in the ethanol industry increased shipments of this fuel additive, as well as shipments of co-products of ethanol production (primarily livestock feed). Fewer shipments of corn and feed grains partially offset the third quarter volume increase, and were the primary driver of the year-to-date volume decrease. Favorable barge rates and Mississippi River navigation conditions led to fewer rail shipments of feed grains for export from the Gulf Coast during both periods.

Automotive – Volume growth and price improvements increased automotive commodity revenue in the third quarter of 2007 compared to 2006. Automotive parts volume was particularly strong in the third quarter driven by an increase in parts shipments and our new intermodal train service between Mexico and Michigan. Shipments of finished vehicles grew 1% in the third quarter as shipments from one domestic manufacturer outpaced volume levels in 2006, which were lower due to extended plant shutdowns.

Chemicals – Volume growth and price increases drove revenue higher in the third quarter and year-to-date periods of 2007 versus the same periods in 2006. New business acquired in June of 2007 drove an increase in third quarter

2007 plastics shipments. Soda ash volume increased as export demand grew in the Gulf area, Pacific Northwest, and Mexico. Strong export demand for potash shipments through the Pacific Northwest and a robust corn planting season to support the ethanol industry drove higher demand for fertilizer shipments. Lower production at Canadian locations boosted liquid and dry chemicals shipments for the year-to-date period at UPRR-served Gulf Coast locations.

Energy – Price increases and higher volume drove revenue growth in the third quarter. Revenue was up year-to-date due to price increases as volume remained flat compared to 2006. Severe storms in the first quarter and heavy rains in May flooded coal pits in the Southern Powder River Basin of Wyoming (SPRB), forced closure of several rail lines, and negatively affected year-to-date volume levels. Shipments from the SPRB were up 3% in the third quarter and down 1% for the year-to-date period of 2007 compared to the same periods of 2006. Conversely, shipments from the Colorado and Utah mines were up 2% and 3% in the third quarter and nine-month periods of 2007, as mine shutdowns and production problems in the first and third quarters of 2006 reduced volumes.

Industrial Products – Continued softening of the housing market, surplus production, and general market uncertainty resulted in lower lumber, paper, and newsprint shipments in both the third quarter and nine-month periods of 2007. In addition, delays in rail expansion projects in Texas, customer production problems, and the on-going impact of a weak residential construction market all combined to reduce stone shipments in both periods of 2007. These lower volumes were partially offset by price increases in both the third quarter and nine-month periods of 2007.

Intermodal – Price increases drove the revenue improvement in the third quarter and nine-month periods of 2007 compared to 2006. Volume was flat versus 2006 as increased domestic and international traffic was offset by lower premium shipments. New service offerings in the second quarter of 2007 contributed to growth in domestic shipments. Increased market share more than offset a general softening of imports from Asia, generating higher international shipments for the third quarter and year-to-date periods of 2007.

Mexico Business – Each of our commodity groups include revenue from shipments to and from Mexico. Revenue from Mexico business increased 7% to $365 million in the third quarter of 2007 and 8% to $1.1 billion for the first nine months of 2007 versus the same periods in 2006. Price increases and volume growth drove the revenue growth in both the quarterly and year-to-date periods.

Operating expenses decreased $45 million in the third quarter of 2007 versus 2006. Network performance, productivity improvements, and investments in capacity primarily drove the cost savings. A smaller workforce, improved car cycle times, and lower personal injury expense more than offset higher wage, benefit and materials inflation, and higher depreciation expense. For the nine-month period of 2007, operating expenses increased $33 million versus 2006. Higher wage, benefit and materials inflation, combined with higher depreciation expense drove the increases. Lower personal injury expense, cost savings realized from operational improvements, and lower volume-related costs partially offset these increases.

Salaries, Wages, and Employee Benefits – Operational improvements led to a 2% decline in our workforce, saving $35 million in wages and $18 million in payroll taxes in the third quarter despite inflationary pressures. Less hiring and training costs, lower backpay expenses associated with the recent labor contract ratifications, and reduced long-term disability costs also contributed to the improvement. Lower volume-related costs and productivity improvements reduced expenses for the year-to-date period of 2007. Conversely, general wage and benefit inflation increased expenses year-to-date, reflecting higher salaries and wages and the impact of higher healthcare costs and other benefit costs.

Fuel and Utilities – Fuel and utilities include locomotive fuel, utilities other than telephone, and gasoline and other fuels. Diesel fuel prices, which averaged $2.29 per gallon (including taxes and transportation costs) in the third quarter of 2007 compared to $2.27 per gallon in the same period in 2006 increased expenses by $6 million. A 3% improvement in our fuel consumption rate reduced fuel expense by $25 million due to the use of newer, more fuel-efficient locomotives, our fuel conservation programs, and an increase in average train size. Volume, as measured by gross ton-miles, was flat in the third quarter versus 2006. Year-to-date, higher diesel prices of $2.12 compared to $2.09 in 2006 contributed $26 million of increased expense. A 2% decrease in gross-ton-miles and a 2% improvement in our fuel consumption rate reduced expenses by $52 million and $30 million, respectively, for the nine months ended September 30, 2007.

Equipment and Other Rents – Equipment and other rents expense primarily includes rental expense the Railroad pays for freight cars owned by other railroads or private companies; freight car, intermodal, and locomotive leases; other specialty equipment leases; and office and other rentals. Lower shipments of industrial products combined with improved car-cycle times driven by network management initiatives drove a $10 million and $40 million reduction in our short-term freight car rental expense in the third quarter and year to-date periods of 2007, respectively, compared to 2006. Lower freight car, intermodal container, and fleet vehicle and equipment lease expense decreased costs by $18 million in the third quarter of 2007. Conversely, higher locomotive lease expense resulted in a $9 million and $26 million increase in costs in the third quarter and year-to-date periods of 2007, respectively, reflecting additional locomotives subject to operating leases.

Depreciation – The majority of depreciation relates to track structure, including rail, ties, and other track material. A higher depreciable asset base, reflecting higher capital spending in recent years, increased depreciation expense in the third quarter and first nine months of 2007.

Materials and Supplies – Materials used to maintain the Railroad’s lines, structures, and equipment are the principal components of materials and supplies expense. This expense item also includes small tools, office supplies, other materials, and the costs of freight services to ship Railroad supplies and materials. Increased use of higher cost components to repair and maintain our fleet of locomotives (including a growing number of units not covered by warranties) added $7 million and $32 million to materials and supplies expense during the third quarter and year-to-date periods, respectively. Conversely, fewer parts were used for freight car repairs due to program maintenance scheduling, which lowered costs and partially offset the increases for the third quarter and year-to-date periods, respectively.

Casualty Costs – Personal injury costs, freight and property damage, insurance, and environmental expense are the primary components of casualty costs. Casualty costs were lower in the third quarter of 2007 compared to the third quarter of 2006, primarily driven by a reduction in personal injury expense. We completed an actuarial study in the third quarter of 2007, which resulted in a reduction in personal injury expense of $47 million, reflecting improvements in our safety experience and lower estimated ultimate settlement costs. Higher insurance costs and increased bad debt expense partially offset the reduction in personal injury expense. For the nine-month period of 2007, actuarial studies completed in the first and third quarters of 2007 resulted in a reduction in personal injury expense of $77 million, which was partially offset by adverse development with respect to one claim.

Purchased Services and Other Costs – Purchased services and other costs include the costs of services purchased from outside contractors, state and local taxes, net costs of operating facilities jointly used by UPRR and other railroads, transportation and lodging for train crew employees, trucking and contracting costs for intermodal containers, leased automobile maintenance expenses, telephone and cellular expense, employee travel expense, and computer and other general expenses. For the third quarter and year-to-date periods, costs increased due to higher contract and consulting fees (including equipment maintenance) of $18 million and $50 million, respectively, and increased crew transportation and lodging costs. State and local tax expense also increased for the year-to-date period. These increases were partially offset by lower drayage expenses in the third quarter and year-to-date periods of 2007 and reduced year-to-date expenses associated with jointly-owned operating facilities. In addition, third quarter and year-to-date comparisons were affected by the settlement of insurance claims totaling $23 million in the third quarter of 2006 related to the 2005 January West Coast storm. The year-to-date comparison was also affected by a $9 million gain in 2006 from the sale of two Company-owned airplanes and increased reimbursable repair work on privately-and foreign-owned freight cars, which reduced second quarter expenses by $14 million in 2006.

Other Income – Other income increased in the third quarter and nine-month periods of 2007 compared to 2006 due to increased gains on real estate sales and higher cash balances combined with higher interest rates, which generated an additional $7 million and $21 million, respectively. Conversely, higher 2007 environmental expense associated with our non-operating properties partially offset the third quarter increases. The comparative impact of the recognition of $14 million of rental income in 2006 resulting from the settlement of a rent dispute covering the period 1994 to 2003 partially offset the higher year-to-date increase in other income.

Interest Expense – Interest expense was higher in the third quarter of 2007 compared to the same period in 2006 driven by an increase in the weighted average debt level of $7.6 billion compared to $7.1 billion in 2006, partially offset by a lower effective interest rate of 6.5% in 2007 compared to 6.8% in 2006. Year-to-date, lower interest expense resulted from a lower effective interest rate of 6.6% in 2007 versus 6.7% in 2006. The weighted average debt level was $7.2 billion in both periods.

Income Taxes – Income taxes were $139 million and $211 million higher in the third quarter and year-to-date periods of 2007 versus 2006 primarily due to higher pre-tax income and the effect of new tax legislation in the State of Illinois that changed how we determine the amount of our income subject to Illinois tax. The Illinois legislation increased our deferred tax expense by $27 million in the third quarter of 2007. Our effective tax rate was 41.3% and 38.8% in the third quarter and year-to-date periods of 2007, respectively, compared to 35.9% and 36.9% in the corresponding periods of 2006.

We report key Railroad performance measures weekly to the Association of American Railroads (AAR), including carloads, average daily inventory of rail cars on our system, average train speed, and average terminal dwell time. We provide this data on our website at www.up.com/investors/reports/index.shtml.

Railroad performance measures reported to the AAR, as well as other performance measures, are included in the table below:

Average Train Speed – Average train speed is calculated by dividing train miles by hours operated on our main lines between terminals. Ongoing network management initiatives and capacity expansion contributed to a 1% improvement in average train speed during the third quarter and nine-month periods of 2007, despite severe weather that affected critical sections of our network and track maintenance.

Average Terminal Dwell Time – Average terminal dwell time is the average time that a rail car spends at our terminals. Lower average terminal dwell time is favorable. Average terminal dwell improved 4% and 9% in the third quarter and year-to-date periods of 2007, respectively, as a result of ongoing management initiatives and directed

efforts to more timely deliver rail cars to our interchange partners and customers. Lower volume levels also contributed to the improvement in our terminal dwell time during the year-to-date period.

Gross and Revenue Ton-Miles – Gross ton-miles are calculated by multiplying the weight of loaded or empty freight cars by the number of miles hauled. Revenue ton-miles are calculated by multiplying the weight of freight by the number of tariff miles. Gross ton-miles were flat for the third quarter and revenue ton-miles increased 2% while carloads increased 1% during the period. A mix shift in intermodal traffic to heavier and longer length of haul shipments impacted revenue ton-miles in relation to carloading growth. Year-to-date, gross ton-miles declined 2% in relation to the 2% decline in carloadings, while revenue ton-miles declined 1% during the period.

Average Full-Time Equivalent Employees – Lower employee levels in the third quarter of 2007 versus 2006 resulted from fewer train and engine personnel due to improved network productivity and fewer management employees, partially offset by more employees maintaining our larger locomotive fleet. Year-to-date, a reduced hiring program, normal attrition levels, and personnel reductions in numerous areas offset year-over-year increases experienced in the first quarter.

Customer Satisfaction Index – The customer satisfaction survey asks customers to rate how satisfied they are with our performance over the last 12 months on a variety of attributes. A higher score indicates higher customer satisfaction. The improvement from survey results in the third quarter and year-to-date periods of 2006 generally reflects customer recognition of our improving service.

Adjusted debt to capital is a non-GAAP financial measure under SEC Regulation G and Item 10 of SEC Regulation S-K. We believe this measure is important to management and investors in evaluating the total amount of leverage in our capital structure, including off-balance sheet lease obligations, which we generally incur in connection with financing the acquisition of locomotives and freight cars and certain facilities. We monitor the ratio of adjusted debt to capital as we manage our capital structure to balance cost effective and efficient access to the capital markets with the Corporation’s overall cost of capital. Adjusted debt to capital should be considered in addition to, rather than as a substitute for, debt to capital. The table above provides support for the adjusted debt to capital calculation. Our September 30, 2007 debt to capital ratios increased as a result of a $1.1 billion increase in debt from December 31, 2006 and purchases of our common stock under our share repurchase program, partially offset by an increase in retained earnings due to higher earnings in the first nine months of 2007.

will continue to explore opportunities to replace existing debt or access capital through issuances of debt securities under our shelf registration, and, therefore, we may issue additional debt securities at any time.

Cash Provided by Operating Activities – Higher income in the first nine months of 2007 and changes in working capital combined to increase cash provided by operating activities. A $50 million voluntary pension contribution during the first quarter of 2006 also contributed to the year-over-year increase. These increases were partially offset by higher management incentive payments during the first quarter of 2007, cash payments representing prior periods’ wage increases in accordance with recent union contract ratifications, and higher income tax payments.

Cash Used in Investing Activities – Higher capital investments and work in process balances drove the increase in cash used in investing in 2007. The third quarter of 2006 included insurance settlement proceeds for property damages resulting from the 2005 West Coast storm.

Cash Used in Financing Activities – Cash used in financing activities decreased in the first nine months of 2007 versus 2006 due to lower debt repayments of $254 million and new debt financing of $1.1 billion, partially offset by the use of $1.2 billion to repurchase common shares and lower net proceeds from equity compensation plans ($47 million in 2007 compared to $122 million in 2006).

Free Cash Flow – Free cash flow is a non-GAAP financial measure under SEC Regulation G. We believe free cash flow is important to management and investors in evaluating our financial performance and measures our ability to generate cash without incurring additional external financings. Free cash flow should be considered in addition to, rather than as a substitute for, cash provided by operating activities. The table below reconciles cash provided by operating activities (GAAP measure) to free cash flow (non-GAAP measure). Year-to-date free cash flow increased compared to 2006 due primarily to higher cash provided by operating activities.

Credit Facilities – On September 30, 2007, we had $1.9 billion of credit available under our new revolving credit facility (the “facility”), which we entered into on April 20, 2007. The facility is designated for general corporate purposes and supports the issuance of commercial paper. The facility was not drawn on as of September 30, 2007. Commitment fees and interest rates payable under the facility are similar to fees and rates available to comparably rated investment-grade borrowers. The facility allows for borrowings at floating rates based on London Interbank Offered Rates, plus a spread, depending upon our senior unsecured debt ratings. The facility requires the maintenance of a debt to net worth coverage ratio. At September 30, 2007, we were in compliance with this covenant. The facility does not include any other financial restrictions, credit rating triggers (other than rating-dependent pricing), or any other provision that could require the posting of collateral. The facility, which expires in April 2012, replaced two $1 billion 5-year facilities with terms ending in March 2009 and March 2010, respectively. The facility includes terms that are comparable with those of the prior facilities, although the minimum net worth requirement of $7.5 billion in prior facilities was removed, and the facility includes a change-of-control provision.

Dividend Restriction – We have a restriction related to the payment of cash dividends to our shareholders due to a debt to net worth covenant requirement under our current revolving credit facility. This facility, entered into on April 20, 2007, no longer has a minimum net worth covenant that was included in our previous facilities, which was more restrictive with respect to the amount of retained earnings available for dividends at December 31, 2006. The amount of retained earnings available for dividends was $11.2 billion and $7.8 billion at September 30, 2007 and December 31, 2006, respectively.

Share Repurchase Program – On January 30, 2007, our Board of Directors authorized the repurchase of up to 20 million shares of Union Pacific Corporation common stock through the end of 2009. The timing and volume of purchases will be guided by management’s assessment of market conditions and other pertinent facts.

Shelf Registration Statement and Significant New Borrowings – Our Board of Directors authorized the issuance of up to $3 billion of debt securities pursuant to a new shelf registration statement, which became effective on March 6, 2007, replacing the $500 million of authority remaining under our shelf registration filed in December 2003. Under the current shelf registration, we may issue, from time to time, any combination of debt securities, preferred stock, common stock, or warrants for debt securities or preferred stock in one or more offerings.

Ratio of Earnings to Fixed Charges – For the three and nine months ended September 30, 2007, our ratio of earnings to fixed charges was 6.0 and 5.1, respectively, compared to 4.5 and 4.2 for the three and nine months ended September 30, 2006, respectively. The ratio of earnings to fixed charges was computed on a consolidated basis. Earnings represent net income, less equity earnings net of distributions, plus fixed charges and income taxes. Fixed charges represent interest charges, amortization of debt discount, and an estimated amount representing the interest portion of rental charges.

Operating Lease Activities – During the nine months ended September 30, 2007, the Railroad, as lessee, entered into long-term operating lease arrangements covering 259 locomotives and 150 rail cars. The lessors under these lease arrangements purchased all 259 locomotives and 150 rail cars from the Corporation through various financing transactions with a total equipment cost of approximately $538 million. In total, these new lease arrangements will provide for minimum rental payments of approximately $831 million, with a present value of approximately $434 million.

The lessors financed the purchase of the locomotives and freight cars, in part, by the issuance of equipment notes that are non-recourse to the Railroad and are secured by assignments of the underlying leases and security interests in the various types of equipment. Neither the Railroad nor UPC guarantees payment of the equipment notes. The Railroad’s obligations to make operating lease payments under the leases are recourse obligations and are not recorded in the Condensed Consolidated Statements of Financial Position.

The Railroad has certain renewal and purchase options with respect to the locomotives and freight cars. If the Railroad does not exercise any such options, the equipment will be returned to the lessors at the end of the lease term.

Off-Balance Sheet Arrangements, Contractual Obligations, and Commercial Commitments

As described in the notes to the Condensed Consolidated Financial Statements and as referenced in the tables below, we have contractual obligations and commercial commitments that may affect our financial condition. However, based on our assessment of the underlying provisions and circumstances of our contractual obligations and commercial commitments, including material sources of off-balance sheet and structured finance arrangements, there is no known trend, demand, commitment, event, or uncertainty that is reasonably likely to occur that would have a material adverse effect on our consolidated results of operations, financial condition, or liquidity. In addition, the commercial obligations, financings, and commitments made by us are customary transactions that are similar to those of other comparable corporations, particularly within the transportation industry.

The following tables identify material obligations and commitments as of September 30, 2007:

Sale of Receivables – The Railroad transfers most of its accounts receivable to Union Pacific Receivables, Inc. (UPRI), a bankruptcy-remote subsidiary, as part of a sale of receivables facility. UPRI sells to investors, without recourse on a 364-day revolving basis, an undivided interest in such accounts receivable. The total capacity to sell undivided interests to investors under the facility was $600 million at both September 30, 2007 and December 31, 2006. The value of the outstanding undivided interest held by investors under the facility was $600 million at both September 30, 2007 and December 31, 2006, respectively. The value of the outstanding undivided interest held by investors is not included in our Condensed Consolidated Financial Statements. The value of the undivided interest held by investors was supported by $1,270 million and $1,158 million of accounts receivable held by UPRI at September 30, 2007 and December 31, 2006, respectively. At September 30, 2007 and December 31, 2006, the value of the interest retained by UPRI was $670 million and $558 million, respectively. This retained interest is included in accounts receivable in our Condensed Consolidated Financial Statements. The interest sold to investors is sold at carrying value, which approximates fair value, and there is no gain or loss recognized from the transaction.

$12 billion and $11 billion during the nine months ended September 30, 2007 and 2006, respectively. UPRI used certain of these proceeds to purchase new receivables under the facility.

Asserted and Unasserted Claims – Various claims and lawsuits are pending against us and certain of our subsidiaries. It is not possible at this time for us to determine fully the effect of all unasserted claims on our consolidated results of operations, financial condition, or liquidity; however, to the extent possible, where unasserted claims are considered probable and where such claims can be reasonably estimated, we have recorded a liability. We do not expect that any known lawsuits, claims, environmental costs, commitments, contingent liabilities, or guarantees will have a material adverse effect on our consolidated results of operations, financial condition, or liquidity after taking into account liabilities previously recorded for these matters.

Indemnities – Our maximum potential exposure under indemnification arrangements, including certain tax indemnifications, can range from a specified dollar amount to an unlimited amount, depending on the nature of the transactions and the agreements. Due to uncertainty as to whether claims will be made or how they will be resolved, we cannot reasonably determine the probability of an adverse claim or reasonably estimate any adverse liability or the total maximum exposure under these indemnification arrangements. We do not have any reason to believe that we will be required to make any material payments under these indemnity provisions.

Accounting Pronouncements – In September 2006, the Financial Accounting Standards Board (FASB) issued Statement No. 157, Fair Value Measurement (FAS 157). While this statement does not require new fair value measurements, it provides guidance on applying fair value and expands required disclosures. FAS 157 is effective for us beginning in the first quarter of 2008. We are currently assessing the impact FAS 157 may have on our Condensed Consolidated Financial Statements.

Labor Negotiations – In January 2005, we began the current round of negotiations with the unions. In June 2007, the Brotherhood of Locomotive Engineers and Trainmen (BLET), the Brotherhood of Maintenance of Way Employees (BMWE), the Brotherhood of Railway Signalmen (BRS), the National Conference of Firemen and Oilers (IBFO), the International Brotherhood of Boilermakers and Blacksmiths (IBBB), and the Sheet Metal Workers (SMW) ratified a five-year agreement that provides for wage increases and increased employee health and welfare cost sharing. The annual wage increases are as follows: July 2005 2.5%; July 2006 3.0%; July 2007 3.0%; July 2008 4.0%; July 2009 4.5%. A second bargaining group consisting of the Transportation Communications International Union (TCU), the Brotherhood of Railway Carman (BRCA), and the International Brotherhood of Electrical Workers (IBEW) ratified the same agreement in September. The International Association of Machinists (IAM) failed to ratify that same agreement in September. We remain in negotiations with the IAM as well as the United Transportation Union (UTU). Existing agreements continue to remain in effect until new agreements are reached or the Railway Labor Act’s procedures (which include mediation, cooling-off periods, and the possibility of Presidential intervention) are exhausted. Contract negotiations with the various unions generally take place over an extended period of time, and we rarely experience work stoppages during negotiations. The current agreements provide for periodic cost of living increases until new agreements are reached.

The Risk Factors in Item 1A of our Annual Report on Form 10-K, filed on February 23, 2007, could affect our future results and could cause those results or other outcomes to differ materially from those expressed or implied in the forward-looking statements, and this report, including this Item 2, should be read in conjunction with these Risk Factors. To the extent circumstances require or we deem it otherwise necessary, we will update or amend these risk factors in a Form 10-Q or Form 8-K. Information regarding new risk factors or material changes to our risk factors, if any, is set forth in Item 1A of Part II of this report.

Forward-looking statements speak only as of the date the statement was made. We assume no obligation to update forward-looking information to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking information. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect thereto or with respect to other forward-looking statements.

There were no material changes to the Quantitative and Qualitative Disclosures About Market Risk previously disclosed in our 2006 Annual Report on Form 10-K.

As of the end of the period covered by this report, the Corporation carried out an evaluation, under the supervision and with the participation of the Corporation’s management, including the Corporation’s Chief Executive Officer (CEO) and Executive Vice President – Finance and Chief Financial Officer (CFO), of the effectiveness of the design and operation of the Corporation’s disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Based upon that evaluation, the CEO and the CFO concluded that, as of the end of the period covered by this report, the Corporation’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the SEC, and that such information is accumulated and communicated to management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Additionally, the CEO and CFO determined that there have been no changes to the Corporation’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

From time to time, the Corporation is involved in legal proceedings, claims, and litigation that occur in connection with the Corporation’s business. Relying upon the latest information available, management routinely assesses the Corporation’s liabilities and contingencies with respect to these matters. Consistent with SEC rules and requirements, the Corporation describes below material pending legal proceedings (other than ordinary routine litigation incidental to the business of the Corporation), material proceedings known to be contemplated by governmental authorities, other proceedings arising under federal, state, or local environmental laws and regulations (including governmental proceedings involving potential fines, penalties, or other monetary sanctions in excess of $100,000), and such other pending matters that the Corporation may determine to be appropriate.

As we reported in our Annual Report on Form 10-K for 2003, the District Attorneys of Merced, Madera, and Stanislaus Counties in California filed a criminal case against the Railroad relating to a series of alleged releases of calcium oxide (lime). The criminal case was dismissed in the last quarter of 2003 and was subsequently refiled as a civil action by several counties in the San Joaquin County Superior Court. The refiled suit sought civil penalties against the Railroad in connection with the release of lime from an unidentified rail car between Chowchilla and Sacramento, California, on December 27, 2001, and another incident in which lime leaked from a rail car between Chowchilla and Stockton, California, on February 21, 2002. The suit contended that regulatory violations occurred by virtue of the Railroad’s alleged failure to timely report the release of a “hazardous material,” its alleged disposal of hazardous waste, and the alleged release of material into the waters of the State of California. On September 20, 2004, the Court dismissed the suit with prejudice. The State of California appealed this decision. On August 2, 2006, the Court of Appeals reversed the judgment and remanded the case for further proceedings consistent with its opinion. The Railroad and the State of California requested that the California Supreme Court review the decision of the Court of Appeals. The California Supreme Court denied review, and the case was remanded to the Superior Court. On August 28, 2007, the State of California voluntarily dismissed its complaint, which concluded this matter.

The Railroad received notice from the Army Corps of Engineers (the Corps) that, during its construction efforts to restore service to the Caliente Subdivision after severe flooding in January 2005, the Railroad may have exceeded its authority under emergency authorizations and permits issued by the Corps. Subsequently, the Corps referred the matter to the United States Environmental Protection Agency (the EPA), which has demanded that the Railroad repair claimed impacts to the adjacent waterway, perform compensatory mitigation, and pay a civil penalty in connection with this project and related stormwater issues. The Railroad and the EPA have discussed the scope of additional work to be performed by the Railroad to address alleged impacts of its construction activities, as well as compensatory mitigation and potential penalties. To date, we have not reached an agreement with the EPA, and, therefore, the ultimate amount of the civil penalty cannot be determined. However, the penalty component of the settlement will exceed $100,000.

We received notices from the EPA and state environmental agencies alleging that we are or may be liable under federal or state environmental laws for remediation costs at various sites throughout the United States, including sites on the Superfund National Priorities List or state superfund lists. We cannot predict the ultimate impact of these proceedings and suits because of the number of potentially responsible parties involved, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs.

As we reported in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2004, we were notified that a qui tam, or private citizen, complaint was filed in the United States District Court for the Central District of California against, among other parties, the City of Long Beach, City of Long Beach Harbor Department, Port of Long Beach (the Port), Union Pacific Corporation, Union Pacific Railroad Company, and Union Pacific Resources Company, also known as Union Pacific Resources Group Inc. (Resources), a former subsidiary of UPC. A private citizen filed the action because the federal government and the State of California elected not to pursue the claims. The complaint alleged that the defendants violated the Federal Civil False Claims Act and the California False Claims Act by conspiring to use public funds to (1) shift environmental cleanup liability to the Port when Resources sold its Terminal Island oil field property to the Port in 1994 and (2) effect the acquisition by the Port of the Terminal Island property in which the Port (or the State of California) allegedly already held certain incidents of title. The complaint sought damages of $2.4 billion, unspecified costs for remediating groundwater contamination, and triple damages

and civil penalties of $10,000 per day. On March 7, 2007, the Court disqualified the private citizen and dismissed the complaint without prejudice. Following this decision, the private citizen-complainant filed in May a notice indicating his intent to appeal the decision of the Court. On August 21, 2007, the Court of Appeals for the Ninth Circuit entered a final dismissal of this matter due to the failure by the plaintiff-complainant to timely initiate the appeal.

As we reported in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2007, 20 small rail shippers (many of whom are represented by the same law firms) filed virtually identical antitrust lawsuits in various federal district courts against us and four other Class I railroads in the U.S. The original plaintiff filed the first of these claims in the U.S. District Court in New Jersey on May 14, 2007, and the additional plaintiffs filed claims in district courts in various states, including Florida, Illinois, Alabama, Pennsylvania, and the District of Columbia. These suits allege that the railroads engaged in price-fixing by establishing common fuel surcharges for certain rail traffic.

We received additional complaints during the third quarter of 2007, increasing the total number of complaints to 26. A few of these suits involve plaintiffs alleging that they are or were indirect purchasers of rail transportation and seeking to represent the class of indirect purchasers of rail transportation that paid fuel surcharges. These complaints have added allegations under state antitrust and consumer protection laws. All of these “copycat” lawsuits (whether filed by direct or indirect purchasers of rail transportation) are being filed by various groups of plaintiffs’ lawyers seeking to become lead counsel in a nationwide class action against the railroads. Each of the plaintiffs requests certification of its complaint as a class-action. On September 27, 2007, the Judicial Panel on Multidistrict Litigation heard arguments regarding which District Court should handle the consolidated complaints, and we expect the panel to issue a decision in November of this year.

Additionally, the Attorney General of a state outside the Railroad’s service area issued a grand jury subpoena to us requesting documents pertaining to our fuel surcharge program. We met with representatives of this Attorney General’s office and expect to have additional meetings in the future in an effort to resolve that office’s interest in this matter.

We deny the allegations that our fuel surcharge program violates the antitrust laws or any other laws. We believe that these lawsuits are without merit, and we will vigorously defend our actions. Therefore, we currently believe that these matters will not have a material adverse effect on any of our results of operations, financial condition, and liquidity.

There were no material changes from the risk factors previously disclosed in our 2006 Annual Report on Form 10-K.
