UNION PACIFIC CORPORATION AND SUBSIDIARY COMPANIES

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

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 six months ended June 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:


	Three Months Ended June 30,		Six Months Ended June 30,
Millions of Dollars	*2007*	2006	*2007*	2006
Stock-based compensation, before tax:
Stock options	$ 5	$4	$ 10	$ 8
Retention awards	6	5	12	12
Total stock-based compensation, before tax	$ 11	$9	$ 22	$ 20
Total stock-based compensation, after tax	$ 7	$5	$ 14	$ 12

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:


Weighted-Average Assumptions		*2007*			2006
Risk-free interest rate		4.9	%		4.5	%
Dividend yield		1.4	%		1.4	%
Expected life (years)		4.7			6.0
Volatility		20.9	%		25.3	%
Weighted-average grant-date fair value of options granted	$	22.34		$	24.97

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 six months ended June 30, 2007 is presented below:


	Shares (thousands)		Weighted- Average Exercise Price	Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value (millions)
Outstanding at December 31, 2006	10,044		$ 64.22	6.0 yrs.	$ 279
Granted	1,098		96.98	N/A	N/A
Exercised	(1,896	)	57.95	N/A	N/A
Forfeited or expired	(15	)	79.55	N/A	N/A
Outstanding at June 30, 2007	9,231		$ 69.38	6.2 yrs.	$ 423
Vested or expected to vest at June 30, 2007	9,169		$ 69.22	6.2 yrs.	$ 421
Options exercisable at June 30, 2007	7,140		$ 62.82	5.4 yrs.	$ 374

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 June 30, 2007 are subject to performance or market-based vesting conditions.

At June 30, 2007, there was $37 million of unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted-average period of 1.8 years. Additional information regarding stock option exercises appears in the table below:


	Three Months Ended June 30,		Six Months Ended June 30,
Millions of Dollars	*2007*	2006	*2007*	2006
Aggregate grant-date fair value of stock options vested	$ -	$ -	$ 10	$ 26
Intrinsic value of stock options exercised	60	24	97	87
Cash received from stock option exercises	42	35	78	131
Tax benefit realized from stock option exercises	22	8	38	32

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 six months ended June 30, 2007 were as follows:


	Shares (thousands)		Weighted-Average Grant-Date Fair Value
Nonvested at December 31, 2006	778		$ 71.72
Granted	306		97.00
Vested	(250	)	61.85
Forfeited	(11	)	78.60
Nonvested at June 30, 2007	823		$ 84.02

Retention awards are granted at no cost to the employee or non-employee director and vest over periods lasting up to four years. At June 30, 2007, there was $46 million of total unrecognized compensation expense related to nonvested retention awards, which is expected to be recognized over a weighted-average period of 2.5 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:


		*2007*
Dividend per share per quarter	$	0.35
Risk-free interest rate at date of grant		4.9	%

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


	Shares (thousands)	Weighted-Average Grant-Date Fair Value
Nonvested at December 31, 2006	122	$ 86.05
Granted	173	93.72
Vested	-	-
Forfeited	-	-
Nonvested at June 30, 2007	295	$ 90.54

At June 30, 2007, there was $19 million of total unrecognized compensation expense related to nonvested performance retention awards, which is expected to be recognized over a weighted-average period of 2.1 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.

4. Financial Instruments

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 June 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:


Millions of Dollars, Except Percentages	June 30, 2007		December 31, 2006
Amount of debt hedged	$ 500		$ 500
Percentage of total debt portfolio	7	%	7	%
Gross fair value liability position	$ (16	)	$ (16	)

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 June 30, 2007 and December 31, 2006, we had a reduction of $4 million and $5 million, respectively, recorded as an accumulated other comprehensive loss that is being amortized on a straight-line basis through September 30, 2014. As of June 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:


	Three Months Ended June 30,			Six Months Ended June 30,
Millions of Dollars	*2007*		2006	*2007*	2006
Increase in interest expense from interest rate hedging	$ 2		$ 2	$ 4	$ 3
Increase/(decrease) in fuel expense from fuel derivatives	(2	)	-	3	-
Decrease in pre-tax income	$ -		$ 2	$ 7	$ 3

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 June 30, 2007 and December 31, 2006. The value of the outstanding undivided interest held by investors under the facility was $600 million at both June 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 $1,188 million and $1,158 million of accounts receivable held by UPRI at June 30, 2007 and December 31, 2006, respectively. At June 30, 2007 and December 31, 2006, the value of the interest retained by UPRI was $588 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 $3.9 billion during both the three months ended June 30, 2007 and 2006, and $7.7 billion and $7.6 billion during the six months ended June 30, 2007 and 2006, respectively. UPRI used certain of these proceeds to purchase new receivables under the facility.

June 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 2006, the sale of receivables program was renewed for an additional 364-day period without any significant changes in terms.

5. Debt

Credit Facilities – On June 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 was designated for general corporate purposes and supports the issuance of commercial paper. The facility was not drawn on as of June 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 June 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 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 June 30, 2007. We must have equivalent credit available under our five-year facility to draw on this $75 million line.

At June 30, 2007, approximately $948 million of short-term borrowings that we intend to refinance were reclassified as long-term debt. This reclassification reflected our ability and intent to refinance these short-term borrowings and 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 $11.6 billion and $7.8 billion at June 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. The net proceeds from this offering 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.

6. Retirement Plans

Pension and Other Postretirement Benefits

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.

Expense

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.

The components of our net periodic pension costs were as follows:


	Pension
	Three Months Ended June 30,				Six Months Ended June 30,
Millions of Dollars	*2007*		2006		*2007*		2006
Service cost	$ 10		$ 8		$ 19		$ 16

Amortization of:
Prior service cost	1		2		3		4
Actuarial loss	4		4		8		9
Net periodic benefit cost	$ 10		$ 9		$ 20		$ 19

The components of our net periodic OPEB costs were as follows:


	OPEB
	Three Months Ended June 30,				Six Months Ended June 30,
Millions of Dollars	*2007*		2006		*2007*		2006

Net periodic benefit cost	$ 1		$ 6		$ 2		$ 11

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


	Three Months Ended June 30,		Six Months Ended June 30,
Millions, Except Per Share Amounts	*2007*	2006	*2007*	2006
Net income	$ 446	$ 390	$ 832	$ 701

Common stock options excluded as their inclusion would be antidilutive	0.6	1.4	0.9	1.4

8. Commitments and Contingencies

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.

Two components primarily drove the personal injury expense reduction in the table below. An actuarial study completed in 2007 lowered personal injury expense by $30 million, reflecting improvements in our safety experience and lower ultimate settlement costs; and the comparative impact of adverse developments with respect to a small group of claims that increased personal injury expense by $19 million in the first six months of 2006. Our personal injury liability activity was as follows:


	Six Months Ended June 30,
Millions of Dollars	*2007*		2006
Beginning balance	$ 631		$ 619
Accruals	91		135
Payments	(86	)	(109	)
Ending balance at June 30	$ 636		$ 645
Current portion, ending balance at June 30	$ 233		$ 272

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 $636 million to $695 million. We believe that the $636 million liability recorded at June 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 with extensive experience in estimating resolution cost for asbestos-related claims to assist us in assessing the number and value of these unasserted claims.

Our asbestos-related liability activity was as follows:


	Six Months Ended June 30,
Millions of Dollars	*2007*		2006
Beginning balance	$ 302		$ 311
Accruals	-		-
Payments	(6	)	(5	)
Ending balance at June 30	$ 296		$ 306
Current portion, ending balance at June 30	$ 13		$ 16

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 June 30, 2007 and December 31, 2006.

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 identified approximately 338 sites at which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 38 sites 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 sites; consequently, our ultimate environmental liability may include costs relating to activities of other parties, in addition to costs relating to our own activities at each site.

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 June 30, 2007, approximately 15% of our environmental liability was discounted at 4.75%, while approximately 14% of our environmental liability was discounted at 5.34% at December 31, 2006.

Our environmental liability activity was as follows:


	Six Months Ended June 30,
Millions of Dollars	*2007*		2006
Beginning balance	$ 210		$ 213
Accruals	11		15
Payments	(24	)	(20	)
Ending balance at June 30	$ 197		$ 208
Current portion, ending balance at June 30	$ 53		$ 49

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 site, 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 June 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 June 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.

9. Other Income – Our other income included the following:


	Three Months Ended June 30,				Six Months Ended June 30,
Millions of Dollars	*2007*		2006		*2007*		2006
Rental income	$ 18		$ 28		$ 35		$ 41
Net gain on non-operating asset dispositions	12		9		17		15
Interest income	12		3		21		8
Sale of receivables fees	(8	)	(9	)	(17	)	(16	)
Non-operating environmental costs and other	2		(2	)	(5	)	(9	)
Total	$ 36		$ 29		$ 51		$ 39

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 any purchases will be guided by management’s assessment of market conditions and other pertinent facts.

As of June 30, 2007, we repurchased approximately 5.7 million shares under this program at an aggregate purchase price of $627 million. 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 ultimate 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 includes $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, other than any applicable interest and penalties, would not affect our effective tax rate.

Primarily because of re-measurement of tax positions for which only the timing of deductibility is uncertain, the total liability for unrecognized tax benefits decreased to $149 million at June 30, 2007. Included in this balance are $125 million of unrecognized tax benefits that, if recognized, would reduce our effective tax rate. This $125 million includes $45 million for interest and penalties. Of the $149 million, $121 million is classified as current in the Condensed Consolidated Statement of Financial Position.

All federal income tax years prior to 1995 are closed. Federal income tax liabilities for tax years 1986 through 1994 have been resolved. Interest calculations for these years are in process and may take several years to resolve with the Internal Revenue Service (IRS). 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. As previously reported, among their proposed adjustments is the disallowance of tax deductions claimed in connection with certain donations of property. In the fourth quarter of 2005, the IRS National Office issued a Technical Advice Memorandum that left unresolved whether the deductions were proper, pending further factual development. We continue to dispute the donation issue, as well as many of the other proposed adjustments, and will contest the associated tax deficiencies through the IRS appeals process, and, if necessary, litigation.

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

We anticipate that we may resolve some or all of the issues related to tax years 1995 through 1998 at IRS Appeals within the next 12 months. If so, then based on our FIN 48 analysis at June 30, 2007, we anticipate payments of $121 million, which will reduce our unrecognized tax benefits by the same amount. However, settlement is uncertain, and if we do not resolve all issues, we may also make a payment in order to begin litigation of any unresolved issues.

We believe it is reasonably possible the State of Illinois will enact new tax legislation in the third quarter that would change how we determine the amount of our income subject to Illinois tax. If enacted, this legislation could increase our deferred tax expense by up to $28 million in the third quarter. In addition, our previously recorded liability for unrecognized tax benefits includes $25 million for a tax position related to determining future Illinois taxable income. If enacted, the legislation would also result in this $25 million being reclassified as a deferred tax liability rather than as a liability for uncertain tax benefits.

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, which is expected to expand fair value measurement, 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.

Critical Accounting Policies and Estimates

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 six 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 ultimate 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.

RESULTS OF OPERATIONS

Quarterly Summary

We reported earnings of $1.65 per diluted share on net income of $446 million in the second quarter of 2007 compared to earnings of $1.44 per diluted share on net income of $390 million for the second quarter of 2006. Year-to-date 2007 net income was $832 million versus $701 million for the same period in 2006. Yield increases, network management initiatives, improved operational efficiency, lower volume-related costs, and lower casualty costs more than offset a decline in volume and cost increases due to inflation, resulting in a 10% and 14% improvement in operating income for the second quarter and year-to-date periods, respectively. In May 2007, heavy rain storms, high winds, and flash flooding damaged our rail network across Kansas, Nebraska, and Missouri. Bridge outages and track washouts reduced shipments. Carloads fell 5% and 3% for the month of May and the second quarter, respectively, compared to 2006 levels. We estimate that the financial impact of the May 2007 storms was approximately $0.10 per diluted share. Year-to-date results also include the adverse impact of severe winter weather on our coal network, extended automotive plant shutdowns, and continued softening in some market sectors.

Operationally, we experienced continued improvement in our network fluidity versus the second quarter of 2006 despite disruptions caused by the severe May weather. As reported to the Association of American Railroads, terminal dwell time and average train speed improved 11% and 2%, respectively, during the second quarter of 2007 compared to the same period of 2006. Focused efforts on terminal processing initiatives and improved asset utilization, combined with reduced volume levels, drove the improvement.

Operating Revenue


		Three Months Ended June 30,			%			Six Months Ended June 30,			%
Millions of Dollars		*2007*		2006	*Change*			*2007*		2006	*Change*
Commodity revenue	$	3,865	$	3,742	3	%	$	7,517	$	7,285	3	%
Other revenue		181		181	-			378		348	9
Total	$	4,046	$	3,923	3	%	$	7,895	$	7,633	3	%

Operating revenue includes commodity revenue and other revenue. 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 four of our six commodity groups increased during the second quarter of 2007, while revenue from automotive shipments remained flat and revenue generated from industrial products shipments declined versus 2006. Commodity revenue grew 3% in the second quarter of 2007 versus the second quarter of 2006 driven by core price increases and index-based contract escalators (formulas in our shipping contracts that correlate price adjustments to certain economic indices), which contributed to a 7% increase in average revenue per car (ARC). Volume decreased 3% during the quarter driven by declines in all commodities except chemical shipments. We experienced the greatest volume declines in the industrial products, agricultural, and energy commodity groups driven in part by the severe May 2007 storms and continued softening in some market sectors. Our fuel surcharge programs (excluding index-based contract escalators that contain some provision for fuel) generated $357 million in commodity revenue in the second quarter of 2007. Fuel surcharge revenue is not comparable to prior periods due to implementation of new mileage-based fuel surcharge programs as discussed below.

Year-to-date, revenue from four of our six commodity groups increased, while revenue from the industrial products and automotive groups declined. Commodity revenue grew 3% in the first half of 2007 versus 2006 driven by core price increases and index-based contract escalators, which contributed to a 6% increase in ARC. Volume decreased 3% year-to-date driven in part by first quarter 2007 harsh winter weather and extended automotive plant shutdowns, continued softening in some market sectors, and the impact of severe rain storms and flash flooding across our central and southern corridors in May 2007. Our fuel surcharge programs (excluding index-based contract escalators

that contain some provision for fuel) generated $696 million in commodity revenue in the first half 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 15% 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 agricultural, chemical, and industrial products shipments, and, to a lesser extent, coal shipments. 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 average revenue per car by commodity type:

Agricultural Products – Price increases primarily drove higher agricultural commodity revenue in the second quarter and year-to-date periods of 2007 versus 2006, despite lower volume levels, which partially offset these gains. Fewer shipments of corn and feed grains primarily drove the second quarter and year-to-date volume decreases. Favorable barge rates and Mississippi river navigation conditions led to fewer rail shipments of feed grains for export from the Gulf Coast for both periods. In addition, lower corn and feed grain exports to Mexico due to price competition and a solid Mexican crop combined to reduce volumes in the second quarter. Year-to-date volumes also declined as soft

production in growing regions serviced by us and an overall weak export market drove lower wheat shipments. Conversely, continuing growth and demand in the ethanol industry increased shipments of this fuel additive, as well as shipments of wet corn milling and co-products of ethanol production (primarily livestock feed). Price increases also were the primary driver of second quarter and year-to-date ARC improvement. Lower fuel surcharges due to lower volume levels and implementation of the new mileage-based fuel surcharge program, which has a higher fuel price entry point, both partially offset improved ARC during the quarter.

Automotive – A decline in vehicle production levels due to plant shutdowns, changes in vehicle distribution patterns, and lower fuel surcharges contributed to the decrease in automotive commodity revenue in the second quarter of 2007, partially offset by price increases. In addition, fewer shipments of finished vehicles from Mexico in the first quarter of 2007, and stronger than usual shipments of finished vehicles in the first quarter of 2006 due to high levels of finished vehicles in manufacturers’ inventories at the end of 2005 contributed to the year-to-date decline. Automotive parts shipments grew in the second quarter and year-to-date periods of 2007 due to increased volumes from domestic manufacturers and new business acquired in mid-2006, partially offset by the loss of shipments from a domestic truck manufacturer. Price increases generated the ARC improvement in both periods, partially offset by lower fuel surcharges and the negative impact of increased automotive parts shipments and lower finished vehicle shipments, which have higher ARC.

Chemicals – Volume growth, price increases and index-based contract escalators increased revenue in the second quarter and year-to-date periods of 2007 versus the same periods in 2006. Lower production at Canadian locations boosted liquid and dry chemicals shipments in the second quarter at Gulf Coast locations serviced by us. 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 in both the second quarter and year-to-date periods. Soda ash shipments also increased as export demand grew in the Gulf area, Pacific Northwest, and Mexico. Price increases were the primary driver of ARC improvement during both periods compared to 2006. While fuel surcharges were higher in the year-to-date period versus 2006, second quarter fuel recoveries were lower year-over-year due to implementation of the new mileage-based fuel surcharge program, which has a higher fuel price entry point.

Energy – Price increases and index-based contract escalators primarily drove the increases in revenue and ARC in the second quarter and six-month periods of 2007 versus 2006. Volume decreased in both periods compared to 2006 as 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 impacted network operations across the Midwest. Shipments from the SPRB were down 5% and 3% in the second quarter and year-to-date periods of 2007 compared to the same periods of 2006. Conversely, shipments from the Colorado and Utah mines were up 3% and 4% in the second quarter and six-month periods of 2007, as mine shutdowns throughout the first half of 2006 limited volume.

Industrial Products – Lower volumes reduced revenue in the second quarter and six-month periods of 2007 versus 2006. Price improvements partially offset this decline. Delays in rail expansion projects in Texas and adverse weather conditions hindering construction and quarry activity, combined with other customer production problems, drove the decline in stone shipments for the second quarter and six-month periods of 2007. Adverse weather conditions impacting quarry activity also contributed to the year-to-date decline in cement shipments. The continued softening of the housing market, surplus production, and general market uncertainty resulted in lower lumber, paper, and newsprint shipments in both periods. Price increases mainly drove the ARC improvement in both periods, partially offset by lower fuel surcharge recovery due to lower volume levels and implementation of the new mileage-based fuel surcharge program, which has a higher fuel price entry point.

Intermodal – Price increases and index-based contract escalators drove the revenue improvement in the second quarter. Carloadings in the second quarter were flat versus 2006 as increased domestic traffic was offset by lower international and premium shipments. New service offerings in the second quarter of 2007 contributed to growth in domestic shipments while international shipments declined year over year due to softer imports and the impact of peak season pre-shipping during the second quarter of 2006. Year-to-date, price increases and index-based contract escalators generated higher revenue and ARC. Volume levels were flat in the first half of the year compared to 2006 as increased import volumes from Asia in the first quarter were offset by decreased premium traffic throughout the six-month period of 2007.

Mexico Business – Each commodity group discussed above includes revenue from shipments to and from Mexico. Revenue from Mexico business increased 6% to $360 million in the second quarter of 2007 and 9% to $709 million for the first half of 2007 versus the same periods in 2006. Price increases drove the revenue growth in both the quarterly and year-to-date periods while volume growth also contributed to year-to-date improvement.

Operating expenses increased $53 million and $78 million in the second quarter and six-month periods of 2007 versus the comparable periods in 2006, respectively. 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 – General wage and benefit inflation increased expenses $32 million and $67 million in the second quarter and year-to-date periods of 2007, reflecting higher salaries and wages and the impact of higher healthcare costs and other benefit costs. Conversely, a 1% decrease in our workforce, lower training expenses for train and engine personnel due to reduced hiring, and lower volume-related costs drove a $13 million reduction in second quarter expenses versus 2006. Year-to-date, workforce levels and training costs were $11 million higher compared to 2006. Lower volume-related costs and operational improvements, boosted by network management initiatives and investment in capacity, generated additional expense reductions for the year-to-date period of 2007.

Fuel and Utilities – Fuel and utilities include locomotive fuel, utilities other than telephone, and gasoline and other fuels. A 4% decrease in gross ton-miles resulted in $31 million lower fuel expense, which was partially offset by higher diesel fuel prices. Our average fuel price was $2.17 per gallon (including taxes and transportation costs) in the second quarter of 2007 compared to $2.15 per gallon in the same period of 2006, which increased expenses by $7 million. Gasoline, utilities, and propane and other fuel expenses increased $4 million in the second quarter of 2007 due to inflation and higher prices. Year-to-date, higher diesel prices of $2.04 compared to $2.01 in 2006 contributed $20 million of increased expense. A 4% decrease in gross-ton-miles and slight improvement in our fuel consumption rate reduced expenses by $51 million and $5 million, respectively, compared to 2006.

Equipment and Other Rents – Equipment and other rents 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, agricultural goods, and finished vehicles combined with improved car-cycle times driven by network management initiatives drove a $12 million and $30 million reduction in our short-term freight car rental expense in the second quarter and year to-date periods of 2007, respectively, compared to 2006. The cycle time improvement for the second quarter was offset by weather-related delays affecting our network. Conversely, higher locomotive lease expense of $9 million and $17 million in the second quarter and year-to-date periods of 2007, respectively, partially offset the lower freight car rental expense.

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 second quarter and first six 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) contributed $12 million and $25 million of the increase during the second 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 second quarter of 2007 compared to the second quarter of 2006 primarily driven by the comparative impact of adverse developments with respect to a small

group of claims, which increased personal injury expense by $5 million in the second quarter of 2006. For the six-month period of 2007, two components of personal injury expense drove casualty costs lower: a semi-annual actuarial study completed in the first quarter of 2007, which lowered personal injury expense by $30 million, reflecting improvements in our safety experience and lower ultimate settlement costs; and the comparative impact of adverse developments with respect to a small group of claims, which increased personal injury expense by $19 million in the first six months of 2006.

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 second quarter and year-to-date periods, costs increased due to higher contract and consulting fees (excluding equipment maintenance) of $5 million and $6 million, respectively; increased crew transportation and lodging of $6 million and $10 million, respectively; higher locomotive and car contract maintenance and repair costs of $4 million and $10 million, respectively; and increased state and local tax expense of $2 million and $4 million, respectively. These increases were offset by lower volume-related drayage expenses of $3 million and $8 million in the second quarter and year-to-date periods of 2007, respectively, and reduced year-to-date expenses of $8 million associated with jointly-owned operating facilities. In addition, the second quarter and year-over-year comparisons were affected by a $9 million gain from the 2006 sale of two Company-owned airplanes and increased reimbursable repair work on privately- and foreign-owned freight cars, which reduced second quarter 2006 expenses by $14 million.

Non-Operating Items


	Three Months Ended June 30,				%		Six Months Ended June 30,				%
Millions of Dollars	*2007*		2006		*Change*		*2007*		2006		*Change*
Other income	$ 36		$ 29		24	%	$ 51		$ 39		31	%
Interest expense	(120	)	(120	)	-		(233	)	(240	)	(3	)
Income taxes	(257	)	(236	)	9		(492	)	(420	)	17

Other Income – Other income increased in the second quarter of 2007 compared to 2006 due to higher interest rates on higher cash balances that generated cash investment returns of $7 million. Lower 2007 environmental expense of $7 million associated with our non-operating properties and higher 2007 lease and track rental income of $4 million were offset by 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.

Interest Expense – Interest expense was flat in the second quarter of 2007 compared to the same period in 2006 driven by weighted average debt levels of $7.1 billion and effective interest rates of 6.7% in both periods. Year-to-date, lower interest expense resulted from a lower weighted average debt level of $7.0 billion in 2007 compared to $7.2 in 2006. The effective interest rate was 6.7% in both periods.

Income Taxes – Income taxes were $21 million and $72 million higher in the second quarter and year-to-date periods of 2007 primarily due to higher pre-tax income, partially offset by additional tax benefits recognized in the second quarter under FIN 48 (See note 11 to the Condensed Financial Statements). Our effective tax rate was 36.6% and 37.2% in the second quarter and year-to-date periods of 2007, respectively, compared to 37.7% and 37.5% in the corresponding periods of 2006, respectively.

OTHER OPERATING/PERFORMANCE AND FINANCIAL STATISTICS

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.

Operating/Performance Statistics

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


	Three Months Ended June 30,				Six Months Ended June 30,
	*2007*	2006	*Change*		*2007*	2006	*Change*
Average train speed (miles per hour)	21.6	21.2	2	%	21.7	21.3	2	%
Average terminal dwell time (hours)	24.7	27.6	(11	)%	25.0	28.3	(12	)%
Gross ton-miles (billions)	260.7	272.1	(4	)%	515.6	535.1	(4	)%
Revenue ton-miles (billions)	139.2	143.4	(3	)%	274.3	282.7	(3	)%
Average full-time equivalent employees	50,755	51,085	(1	)%	50,764	50,673	-	%
Customer satisfaction index	80	69	11	pt	80	69	11	pt

Average Train Speed – Average train speed is calculated by dividing train miles by hours operated on our main lines between terminals. Lower volume levels, ongoing network management initiatives and capacity expansion contributed to a 2% improvement in average train speed during the second quarter and six-month periods of 2007, despite severe winter weather conditions in the first quarter and May storms affecting critical sections of our network.

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 11% and 12% in the second 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 drove improvement in our terminal dwell time.

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 declined 4% for the second quarter and year-to-date periods while revenue ton-miles and carloads declined 3% in both periods versus 2006. Our higher density shipments of industrial products, agricultural, and energy commodities declined in both periods of 2007, impacting gross ton-miles.

Average Full-Time Equivalent Employees – Lower employee levels in the second quarter of 2007 versus 2006 resulted from fewer train and engine personnel due to lower volume levels, partially offset by more employees maintaining our larger locomotive and freight car fleet. Year-to-date, employee levels were flat as 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 service over the last 12 months on a variety of attributes. A higher score indicates higher customer satisfaction. The improvement over the second quarter and year-to-date periods of 2007 generally reflects customer recognition of our improving service.

Adjusted capital (b)	$ 26,556		$ 26,205
Adjusted debt to capital (a/b)	41.8	%	41.6	%

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 June 30, 2007 debt to capital ratios increased as a result of a $456 million 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 half of 2007.

On April 18, 2007, we issued a total of $500 million of 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. The net proceeds from this offering are for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities also include change-of-control provisions.

LIQUIDITY AND CAPITAL RESOURCES

Cash used in financing activities	(282	)	(360	)
Net change in cash and cash equivalents	$ (305	)	$ (511	)

Cash Provided by Operating Activities – Higher income in the first half 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 Used in Investing Activities – We acquired more locomotives pending completion of long-term financing arrangements in the first half of 2007 compared to the same period of 2006. The increase was partially offset by lower capital investments.

The table below details our cash capital investments.


	Six Months Ended June 30,

Capacity and commercial facilities	189	246
Locomotives and freight cars	55	56
Other	59	35
Total	$ 1,101	$ 1,131

Cash Used in Financing Activities – Cash used in financing activities decreased in the first half of 2007 versus 2006 due to lower debt repayments of $258 million and new debt financing of $494 million, partially offset by the use of $604 million to repurchase common shares and lower net proceeds from equity compensation plans ($52 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). First half 2007 free cash flow increased compared to the first half of 2006 due primarily to higher cash provided by operating activities. We typically report negative free cash flow in the first half of the year.

Financing Activities

Credit Facilities – On June 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 was designated for general corporate purposes and supports the issuance of commercial paper. The facility was not drawn on as of June 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 June 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 was removed, and the facility includes a change-of-control provision.

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 $11.6 billion and $7.8 billion at June 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 any 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 six months ended June 30, 2007, our ratio of earnings to fixed charges was 4.9 and 4.7, respectively, compared to 4.4 and 4.1 for the three and six months ended June 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.

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 June 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 to investors. The total capacity to sell undivided interests to investors under the facility was $600 million at both June 30, 2007 and December 31, 2006. The value of the outstanding undivided interest held by investors under the facility was $600 million at both June 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 $1,188 million and $1,158 million of accounts receivable held by UPRI at June 30, 2007 and December 31, 2006, respectively. At June 30, 2007 and December 31, 2006, the value of the interest retained by UPRI was $588 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.

$3.9 billion during both the three months ended June 30, 2007 and 2006, and $7.7 billion and $7.6 billion during the six months ended June 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 $8 million and $9 million for the three months ended June 30, 2007 and 2006, respectively, and $17 million and $16 million for the six months ended June 30, 2007 and 2006, respectively. The costs include interest, program fees paid to banks, commercial paper issuing costs, and fees for unused commitment availability.

OTHER MATTERS

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 four unions reached a tentative agreement with the same provisions in July. Ratification results will be known in September. We remain in negotiations with one additional union. 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.

CAUTIONARY INFORMATION

Certain statements in this report, and statements in other reports or information filed or to be filed with the SEC (as well as information included in oral statements or other written statements made or to be made by us), are, or will be, forward-looking statements as defined by the Securities Act of 1933 and the Securities Exchange Act of 1934. These forward-looking statements include, without limitation, statements and information set forth under the

caption “2007 Outlook” in Item 7 of our 2006 Annual Report on Form 10-K, and any other statements or information in this report (including information incorporated herein by reference) regarding: expectations as to operational or service improvements; expectations regarding the effectiveness of steps taken or to be taken to improve operations, service, infrastructure improvements, transportation plan modifications, and management of customer traffic on the system to meet demand; expectations as to cost savings, revenue growth, and earnings; the time by which goals, targets, or objectives will be achieved; projections, predictions, expectations, estimates, or forecasts as to our business, financial and operational results, future economic performance, and general economic conditions; proposed new products and services; estimates of costs relating to environmental remediation and restoration; expectations that claims, litigation, environmental costs, commitments, contingent liabilities, labor negotiations or agreements, or other matters will not have a material adverse effect on our consolidated results of operations, financial condition, or liquidity and any other similar expressions concerning matters that are not historical facts.

Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times that, or by which, such performance or results will be achieved. Forward-looking information is subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in the statements.

Forward-looking statements and information reflect the good faith consideration by management of currently available information, and may be based on underlying assumptions believed to be reasonable under the circumstances. However, such information and assumptions (and, therefore, such forward-looking statements and information) are or may be subject to variables or unknown or unforeseeable events or circumstances over which management has little or no influence or control. 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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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.

Item 4. Controls and Procedures

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.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, the Corporation is involved in legal proceedings, claims, and litigation that occur in connection with the Corporation’s business. Management routinely assesses the Corporation’s liabilities and contingencies in connection with these matters based upon the latest information available. 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.

Environmental Matters

As we reported in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2003, the San Joaquin County District Attorney filed an action against the Railroad on February 3, 2003, in the San Joaquin County Superior Court alleging claims under the California Business and Professions Code section 17200 (unfair business practices), Fish and Game Code section 5650 and 5650.1, California Health and Safety Code section 25189(d), and Public Nuisance, California Civil Code section 3480. The claims arose from a February 16, 2000, derailment in Stockton, California, in which a locomotive struck an object on the tracks, puncturing a fuel tank. The District Attorney alleged that diesel fuel from this spill entered waters of the State of California. The complaint also asserted claims under the above referenced statutes for any other diesel spill that may have occurred in the State of California between 2000 and 2003, in which diesel may have passed into waters of the State of California. The District Attorney filed an amended complaint on April 10, 2003, which narrowed the claims to the incident of February 16, 2000. On April 30, 2007, the court exercised its discretion and dismissed this pending action brought by the District Attorney of San Joaquin County against the Railroad.

We received notices from 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.

Other Matters

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 alleges 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. The private citizen-complainant filed a notice indicating his intent to appeal the decision of the Court on May 24, 2007.

Twenty 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 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. The plaintiffs request certification of their complaints as a class-action on behalf of all shippers who paid fuel surcharges on the specified types of rail shipments. The Judicial Panel on Multidistrict Litigation will determine which district court will receive these cases for consolidated handling. Additionally, the Attorney General of a state outside of the Railroad’s service area recently issued a grand jury subpoena to us requesting documents pertaining to our fuel surcharge program. We deny the allegations that our fuel surcharge program violates the antitrust 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.
