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. Basis of Presentation

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). Our Consolidated Statement of Financial Position at December 31, 2010, 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 2010 Annual Report on Form 10-K. The results of operations for the six months ended June 30, 2011, are not necessarily indicative of the results for the entire year ending December 31, 2011.

The Condensed Consolidated Financial Statements are presented in accordance with accounting principles generally accepted in the United States of America as codified in the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC).

2. Accounting Pronouncements

In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (ASU 2011-05). ASU 2011-05 will require companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements. It eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The standard does not change the items which must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. This standard is effective for interim and annual periods beginning after December 15, 2011. Because this ASU impacts presentation only, it will have no effect on our financial condition, results of operations or cash flows.

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. The following table provides freight revenue by commodity group:

Although our revenues are principally derived from customers domiciled in the U.S., the ultimate points of origination or destination for some products transported are outside the U.S.

4. 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 have elected to issue treasury shares to cover option exercises and stock unit vestings, while new shares are issued when retention shares are granted. 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. 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 six months ended June 30, 2011 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 June 30, 2011 are subject to performance or market-based vesting conditions.

At June 30, 2011, there was  $25 million of unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted-average period of 1.2 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 on the grant date. Dividends and dividend equivalents are paid to participants during the vesting periods.

Changes in our retention awards during the six months ended June 30, 2011 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 June 30, 2011, there was  $90 million of total unrecognized compensation expense related to nonvested retention awards, which is expected to be recognized over a weighted-average period of 2 years.

Performance Retention Awards – In February 2011, our Board of Directors approved performance stock unit grants. Other than different performance targets, the basic terms of these performance stock units are identical to those granted in February 2009 and February 2010, including using annual return on invested capital (ROIC) as the performance measure. We define ROIC as net operating profit adjusted for interest expense (including interest on the present value of operating leases) and taxes on interest divided by average invested capital adjusted for the present value of operating leases.

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 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 related to the February 2011 grant were as follows:

Changes in our performance retention awards during the six months ended June 30, 2011 were as follows:

At June 30, 2011, there was  $45 million of total unrecognized compensation expense related to nonvested performance retention awards, which is expected to be recognized over a weighted-average period of 1.6 years. A portion of this expense is subject to achievement of the ROIC levels established for the performance stock unit grants.

5. 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 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 cost were as follows:

The components of our net periodic OPEB cost/(benefit) were as follows:

6. Other Income

Other income included the following:

7. Income Taxes

Internal Revenue Service (IRS) examinations have been completed and settled for all years prior to 1999, and the statute of limitations bars any additional tax assessments. Interest calculations may remain open for years prior to 1999. The IRS has completed its examinations and issued notices of deficiency for tax years 1999 through 2006. We disagree with many of their proposed adjustments, and we are at IRS Appeals for these years. During the second quarter of 2011, the IRS completed its examination and issued a notice of deficiency for tax years 2007 and 2008. We disagree with many of their proposed adjustments, and will contest the adjustments through the IRS Appeals process and potentially through litigation. We anticipate a partial settlement of the tax years 1999 through 2004 in the next 12 months. Several state tax authorities are examining our state income tax returns for tax years 2003 through 2006.

Based on the IRS's examination report for tax years 2007 and 2008, we increased our liability for uncertain tax benefits from  $86 million at December 31, 2010, to  $149 million at June 30, 2011. Most of this increase is a reclassification from our deferred income tax liability. Of the  $149 million, we have classified  $78 million as current in anticipation of a partial settlement in the next 12 months for tax years 1999 through 2004.

In February 2011, Arizona enacted legislation that will decrease the state's corporate tax rate. This reduced our deferred tax expense by  $14 million in the first quarter of 2011.

8. Earnings Per Share

The following table provides a reconciliation between basic and diluted earnings per share:

9. Comprehensive Income

Comprehensive income was as follows:

The after-tax components of accumulated other comprehensive loss were as follows:

10. Accounts Receivable

Accounts receivable includes freight and other receivables reduced by an allowance for doubtful accounts. The allowance is based upon historical losses, credit worthiness of customers, and current economic conditions. At June 30, 2011 and December 31, 2010, our accounts receivable were reduced by  $6 million and  $5 million, respectively. Receivables not expected to be collected in one year and the associated allowances are classified as other assets in our Condensed Consolidated Statements of Financial Position. At June 30, 2011 and December 31, 2010, receivables classified as other assets were reduced by allowances of  $49 million and  $51 million, respectively.

Receivables Securitization Facility – Under the receivables securitization facility, the Railroad sells most of its accounts receivable to Union Pacific Receivables, Inc. (UPRI), a bankruptcy-remote subsidiary. UPRI may subsequently transfer, without recourse on a 364-day revolving basis, an undivided interest in eligible accounts receivable to investors. The total capacity to transfer undivided interests to investors under the facility was  $600 million at June 30, 2011 and December 31, 2010. The value of the outstanding undivided interest held by investors under the facility was  $100 million at June 30, 2011 and December 31, 2010, and is included in our Condensed Consolidated Statements of Financial Position as debt due after one year. The value of the undivided interest held by investors was supported by  $1.1 billion and  $960 million of accounts receivable at June 30, 2011, and December 31, 2010, respectively. At June 30, 2011, and December 31, 2010, the value of the interest retained by UPRI was  $1.1 billion and  $960 million, respectively. This retained interest is included in accounts receivable, net in our Condensed Consolidated Statements of Financial Position.

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 ratios increase one percent, the value of the outstanding undivided interest held by investors would not change as of June 30, 2011. 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 collected approximately  $4.6 billion and  $4.0 billion during the three months ended June 30, 2011 and 2010, respectively, and  $8.9 billion and  $7.7 billion during the six months ended June 30, 2011 and 2010, respectively. UPRI used certain of these proceeds to purchase new receivables under the facility.

The costs of the receivables securitization facility include interest, which will vary based on prevailing commercial paper rates, program fees paid to banks, commercial paper issuing costs, and fees for unused commitment availability. The costs of the receivables securitization facility are included in interest expense and were  $1 million for the three months ended June 30, 2011 and 2010, and  $2 million and  $3 million for the six months ended June 30, 2011, and 2010, respectively.

The investors have no recourse to the Railroad's other assets except for customary warranty and indemnity claims. Creditors of the Railroad do not have recourse to the assets of UPRI.

We are currently in process of renewing the receivables securitization facility for an additional 364-day period at comparable terms and conditions.

11. Properties

The following tables list the major categories of property and equipment, as well as the weighted average composite depreciation rate for each category:

12. Accounts Payable and Other Current Liabilities

13. 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 at inception, 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.

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 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, 2011 and December 31, 2010, we had reductions of  $2 million and  $3 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, 2011 and December 31, 2010, we had no interest rate cash flow hedges outstanding.

Earnings Impact – Our use of derivative financial instruments had the following impact on pre-tax income for the six months ended June 30:

Fair Value of Financial Instruments – The fair value of our short- and long-term debt was estimated using quoted market prices, where available, or current borrowing rates. At June 30, 2011, the fair value of total debt was  $9.9 billion, approximately  $1.0 billion more than the carrying value. At December 31, 2010, the fair value of total debt was  $10.4 billion, approximately  $1.2 billion more than the carrying value. At June 30, 2011 and December 31, 2010, approximately  $303 million of fixed-rate debt securities contained call provisions that allow us to retire the debt instruments prior to final maturity, with the payment of fixed call premiums, or in certain cases, at par. The fair value of our cash equivalents approximates their carrying value due to the short-term maturities of these instruments.

14. Debt

Credit Facilities – During the second quarter of 2011, we replaced our  $1.9 billion revolving credit facility, which would have expired in April 2012, with a new  $1.8 billion facility that expires in May 2015 (the facility). The facility is based on substantially similar terms as those in the previous credit facility. On June 30, 2011, we had  $1.8 billion of credit available under the facility, which is designated for general corporate purposes and supports the issuance of commercial paper. We did not draw on the facility during the six months ended June 30, 2011. 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 Union Pacific Corporation to maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing. At June 30, 2011, and December 31, 2010 (and at all times during the first and second quarters), we were in compliance with this covenant.

The definition of debt used for purposes of calculating the debt-to-net-worth coverage ratio includes, among other things, certain credit arrangements, capital leases, guarantees and unfunded and vested pension benefits under Title IV of ERISA. At June 30, 2011, the debt-to-net-worth coverage ratio allowed us to carry up to  $36.6 billion of debt (as defined in the facility), and we had  $9.3 billion of debt (as defined in the facility) outstanding at that date. Under our current capital plans, we expect to continue to satisfy the debt-to-net-worth coverage ratio; however, many factors beyond our reasonable control could affect our ability to comply with this provision in the future. The facility does not include any other financial restrictions, credit rating triggers (other than rating-dependent pricing), or any other provision that could require us to post collateral. The facility also includes a  $75 million cross-default provision and a change-of-control provision.

During the six months ended June 30, 2011, we did not issue or repay any commercial paper, and at June 30, 2011, we had no commercial paper outstanding. Outstanding commercial paper balances are supported by our revolving credit facility but do not reduce the amount of borrowings available under the facility.

Shelf Registration Statement and Significant New Borrowings – Under our 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. 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.

As of June 30, 2011, and December 31, 2010, we reclassified as long-term debt approximately  $574 million and  $100 million, respectively, of debt due within one year that we intend to refinance. This reclassification reflects our ability and intent to refinance any short-term borrowings and certain current maturities of long-term debt on a long-term basis.

Debt Exchange – On May 23, 2011, we announced the commencement of a private offer to exchange various outstanding notes and debentures due between 2013 and 2019 (Existing Notes). The exchange transaction closed on June 23, 2011, at which time  $857 million of Existing Notes were exchanged for  $750 million of 4.163% notes (New Notes) due July 15, 2022, plus cash consideration of approximately  $267 million and  $17 million for accrued and unpaid interest on the Existing Notes. The cash consideration, which will be recorded as an adjustment to the carrying value of debt, and the balance of the unamortized discount and issue costs from the Existing Notes will be amortized as an adjustment of interest expense over the term of the New Notes. No gain or loss will be recognized as a result of the exchange. Costs related to the debt exchange that are payable to parties other than the debt holders total approximately  $6 million and are included in interest expense during the second quarter.

The following table lists the outstanding notes and debentures that were exchanged:

Debt Redemption – On March 22, 2010, we redeemed  $175 million of our 6.5% notes due April 15, 2012. The redemption resulted in an early extinguishment charge of  $16 million in the first quarter of 2010.

15. Variable Interest Entities

We have entered into various lease transactions in which the structure of the leases contain variable interest entities (VIEs). These VIEs were created solely for the purpose of doing lease transactions (principally involving railroad equipment and facilities) and have no other activities, assets or liabilities outside of the lease transactions. Within these lease arrangements, we have the right to purchase some or all of the assets at fixed prices. Depending on market conditions, fixed-price purchase options available in the leases could potentially provide benefits to us; however, these benefits are not expected to be significant.

We maintain and operate the assets based on contractual obligations within the lease arrangements, which set specific guidelines consistent within the railroad industry. As such, we have no control over activities that could materially impact the fair value of the leased assets. We do not hold the power to direct the activities of the VIEs and, therefore, do not control the ongoing activities that have a significant impact on the economic performance of the VIEs. Additionally, we do not have the obligation to absorb losses of the VIEs or the right to receive benefits of the VIEs that could potentially be significant to the VIEs.

We are not considered to be the primary beneficiary and do not consolidate these VIEs because our actions and decisions do not have the most significant effect on the VIE's performance and our fixed-price purchase price options are not considered to be potentially significant to the VIE's. The future minimum lease payments associated with the VIE leases totaled  $4.1 billion as of June 30, 2011.

16. Commitments and Contingencies

Asserted and Unasserted Claims – Various claims and lawsuits are pending against us and certain of our subsidiaries. We cannot fully determine the effect of all asserted and unasserted claims on our consolidated results of operations, financial condition, or liquidity; however, to the extent possible, where asserted and 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 and insurance recoveries 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 an actuarial analysis to measure the expense and liability, including unasserted claims. The Federal Employers' Liability Act (FELA) governs compensation for work-related accidents. Under FELA, damages are assessed based on a finding of fault through litigation or out-of-court settlements. We offer a comprehensive variety of services and rehabilitation programs for employees who are injured at work.

Our personal injury liability is discounted to present value using applicable U.S. Treasury rates. Approximately 88% of the recorded liability is related to asserted claims, and approximately 12% is related to unasserted claims at June 30, 2011. Estimates can vary over time due to evolving trends in litigation.

Our personal injury liability activity was as follows:

Asbestos – We are a defendant in a number of lawsuits in which current and former employees and other parties allege exposure to asbestos. We assess our potential liability using a statistical analysis of resolution costs for asbestos-related claims. This liability is updated annually and excludes future defense and processing costs. The liability for resolving both asserted and unasserted claims was based on the following assumptions:

• The ratio of future claims by alleged disease would be consistent with historical averages.
• The number of claims filed against us will decline each year.
• The average settlement values for asserted and unasserted claims will be equivalent to historical averages.
• The percentage of claims dismissed in the future will be equivalent to historical averages.

Our liability for asbestos-related claims is not discounted to present value due to the uncertainty surrounding the timing of future payments. Approximately 20% of the recorded liability related to asserted claims and approximately 80% related to unasserted claims at June 30, 2011.

Our asbestos-related liability activity was as follows:

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, 2011, and December 31, 2010.

We believe that our estimates of liability for asbestos-related claims and insurance recoveries are reasonable and probable. 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 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 also may vary in the future if strategies, activities, and outcomes of asbestos litigation materially change; federal and state laws governing asbestos litigation increase or decrease the probability or amount of compensation of claimants; and there are material changes with respect to payments made to claimants by other defendants.

Environmental Costs – We are subject to federal, state, and local environmental laws and regulations. We have identified 294 sites at which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 33 sites that are the subject of actions taken by the U.S. government, 17 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 we identify an environmental issue with respect to property owned, leased, or otherwise used in 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, 2011, less than 1% of our environmental liability was discounted at 3.2%, while approximately 5% of our environmental liability was discounted at 2.8% at December 31, 2010.

Our environmental liability activity was as follows:

The environmental liability includes future costs for remediation and restoration of sites, as well as 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. The ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties, 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 of liability may vary over time due to changes in federal, state, and local laws governing environmental remediation. Current obligations are not expected to have a material adverse effect on our consolidated results of operations, financial condition, or liquidity.

Guarantees – At June 30, 2011, we were contingently liable for  $358 million in guarantees. We have recorded a liability of  $2 million and  $3 million for the fair value of these obligations as of June 30, 2011, and December 31, 2010, respectively. 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.

Operating Leases – At June 30, 2011, we had commitments for future minimum lease payments under operating leases with initial or remaining non-cancelable lease terms in excess of one year of approximately  $4.7 billion.

17. Share Repurchase Program

The shares repurchased in the first quarter, shown in the table below, were repurchased under our authorized share repurchase program that expired on March 31, 2011. Effective April 1, 2011, our Board of Directors authorized the repurchase of 40 million common shares of UPC by March 31, 2014, replacing our previous repurchase program. The shares repurchased in the second quarter, shown in the table below, were purchased under the new program. As of June 30, 2011, we had repurchased a total of  $4.8 billion of UPC common stock since the commencement of purchases under our repurchase programs.

Management's assessments of market conditions and other pertinent facts guide the timing and volume of all repurchases. We expect to fund any share repurchases under this program through cash generated from operations, the sale or lease of various operating and non-operating properties, debt issuances, and cash on hand. Repurchased shares are recorded in treasury stock at cost, which includes any applicable commissions and fees.
