Item 8.01 Other Events.

Union Pacific Corporation (the Company) is filing this Current Report on Form 8-K (Form 8-K) to reflect the impact of a change from an acceptable accounting principle to a preferable accounting principle on the financial information contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, which was filed with the Securities and Exchange Commission (SEC) on February 5, 2010 (Form 10-K). The information in this Form 8-K is not an amendment to or restatement of the Form 10-K.

We historically accounted for rail grinding costs as a capital asset. Effective January 1, 2010, we changed our accounting policy for rail grinding costs from a capitalization method, under which we capitalized the cost of rail grinding and depreciated such capitalized costs, to a direct expense method, under which we expense rail grinding costs as incurred. This change was reflected as a change in accounting principle from an acceptable accounting principle to a preferable accounting principle. The expense as incurred method is preferable, as it eliminates the subjectivity in determining the period of benefit associated with rail grinding over which to depreciate the associated capitalized costs. When the accounting principle was retrospectively applied, as shown in this Form 8-K, net income for the years ended December 31, 2009, 2008, and 2007 decreased by $8 million, $3 million, and $7 million, or $0.01, $0.01, and $0.02 per share, respectively.

The following Items of the Form 10-K have been presented retrospectively to reflect the change in accounting principle for rail grinding and are attached as Exhibit 99.1 to this Form 8-K:

PART II

Item 5. Market for the Registrant’s Common Equity, Related Stockholder Matters, and Issuer Purchases of Equity Securities

Our common stock is traded on the NYSE under the symbol “UNP”. On May 28, 2008, we completed a two-for-one stock split, effected in the form of a 100% stock dividend. The stock split entitled all shareholders of record at the close of business on May 12, 2008, to receive one additional share of our common stock, par value $2.50 per share, for each share of common stock held on that date. All references to common shares and per share information have been restated to reflect the stock split for all periods presented. The following table presents the dividends declared and the high and low closing prices of our common stock for each of the indicated quarters.

2009 - Dollars Per Share	Q1		Q2		Q3		Q4
Dividends	$	0.27	$	0.27	$	0.27	$	0.27
Common stock price:
High		54.66		55.45		64.75		66.73
Low		33.28		39.82		47.47		54.20
2008 - Dollars Per Share
Dividends	$	0.22	$	0.22	$	0.27	$	0.27
Common stock price:
High		65.29		82.76		85.80		71.78
Low		52.66		62.98		67.34		41.84

At January 29, 2010, there were 505,286,368 shares of outstanding common stock and 34,116 common shareholders of record. On that date, the closing price of the common stock on the NYSE was $60.50. We have paid dividends to our common shareholders during each of the past 110 years. We declared dividends totaling $544 million in 2009 and $501 million in 2008. On July 31, 2008, we increased the quarterly dividend to $0.27 per share, payable beginning on October 1, 2008, to shareholders of record on August 29, 2008. We are subject to certain restrictions regarding retained earnings with respect to the payment of cash dividends to our shareholders. The amount of retained earnings available for dividends increased to $11.6 billion at December 31, 2009, from $10.4 billion at December 31, 2008. See discussion of this restriction in Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources, Item 7. We do not believe the restriction on retained earnings will affect our ability to pay dividends, and we currently expect to pay dividends in 2010 comparable to 2009.

Comparison Over One- and Three-Year Periods – The following table presents the cumulative total shareholder returns, assuming reinvested dividends, over one- and three-year periods for the Corporation, a peer group index (comprised of Burlington Northern Santa Fe Corporation, CSX Corporation, and Norfolk Southern Corporation), the Dow Jones Transportation Index (Dow Jones), and the Standard & Poor’s 500 Stock Index (S&P 500).

Period	UPC		Peer Group		Dow Jones		S&P 500
1 Year (2009)		36.6%		31.1%		18.6%		26.5%
3 Year (2007-2009)		46.0		33.5		(5.5)		(15.9)

Five-Year Performance Comparison – The following graph provides an indicator of cumulative total shareholder returns for the Corporation as compared to the peer group index (described above), the Dow Jones, and the S&P 500. The graph assumes that the value of the investment in the common stock of Union Pacific Corporation and each index was $100 on December 31, 2004, and that all dividends were reinvested.

Purchases of Equity Securities – During 2009, we repurchased shares of our common stock at an average price of $55.48 solely in connection with transactions with employees under equity compensation arrangements. The following table presents common stock repurchases during each month for the fourth quarter of 2009:

Period	Total Number of Shares Purchased [a]		Average Price Paid Per Share		Total Number of Shares Purchased as Part of a Publicly Announced Plan or Program [b]		Maximum Number of Shares That May Yet Be Purchased Under the Plan or Program [b]
Oct. 1 through Oct. 31		5,508		$    63.62		-		32,577,090
Nov. 1 through Nov. 30		69,523		64.90		-		32,577,090
Dec. 1 through Dec. 31		13,150		65.48		-		32,577,090
Total		88,181		$    64.91		-		N/A

[a] Total number of shares purchased during the quarter represents shares delivered or attested to UPC by employees to pay stock option exercise prices, satisfy excess tax withholding obligations for stock option exercises or vesting of retention units, and pay withholding obligations for vesting of retention shares.

[b] On January 30, 2007, our Board of Directors authorized us to repurchase up to 40 million shares of our common stock through December 31, 2009. On May 1, 2008, our Board of Directors authorized additional repurchases of up to 40 million shares of our common stock through March 31, 2011. We did not repurchase any shares under this publicly announced plan during 2009. These repurchases may be made on the open market or through other transactions. Our management has sole discretion with respect to determining the timing and amount of these transactions.

[e] Operating margin is defined as operating income divided by operating revenues. Operating ratio is defined as operating expenses divided by operating revenues.

[f] Debt to capital is determined as follows: total debt divided by total debt plus equity.

[g] Return on average common shareholders’ equity is determined as follows: Net income divided by average common shareholders’ equity.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the Consolidated Financial Statements and applicable notes to the Financial Statements and Supplementary Data, Item 8, and other information in this report, including Risk Factors set forth in Item 1A and Critical Accounting Policies and Cautionary Information at the end of this Item 7.

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

EXECUTIVE SUMMARY

2009 Results

• Safety – During 2009, we continued our positive, multi-year trend in safety performance by setting records in many of our safety metrics. The employee injury incident rate per 200,000 man-hours declined 12% from 2008 to its lowest level ever. Our continued focus on derailment prevention resulted in a 10% reduction in our incident rate in 2009, with associated costs declining 3%. With respect to public safety, we closed 353 grade crossings to reduce our exposure to incidents. We also continued installing video cameras on our road locomotives, which assist us in reviewing grade crossing incidents, and we now have camera-equipped locomotives in the lead position of over 95% of our road trains. During 2009, we had the lowest number of crossing incidents on record, and the rate of grade crossing incidents per million train miles decreased 11%. Also, we have implemented extensive trespass reduction programs, and trespasser incidents declined 28% during the year. These improvements reflect comprehensive efforts to enhance employee training, increase public education, make targeted capital investments, and eliminate or reduce safety risks.

• Financial Performance – In 2009, we generated operating income of $3.4 billion despite economic conditions that significantly reduced demand for our services across almost all market sectors. While a 16% reduction in volume drove the 17% decrease in operating income, core pricing gains, improved productivity, and cost savings from demand-driven resource adjustments translated into an all-time record operating ratio of 76.1% for 2009, outpacing our previous record of 77.4% set in 2008. Net income of $1.9 billion declined from $2.3 billion in 2008, but resulted in earnings of $3.74 per diluted share for 2009, surpassed only by financial results in 2008.

• Freight Revenues – Our freight revenues declined 22% year-over-year to $13.4 billion. Freight revenues and volumes for all six commodity groups decreased, reflecting adverse economic conditions. Overall, volume decreased 16% in 2009, with the largest declines in automotive and industrial products shipments. Lower fuel surcharges due to lower fuel prices also reduced freight revenues for the year, partially offset by core pricing gains. We continued to focus on improving the reinvestibility of our business and we have repriced approximately 85% of our business since 2004.

• Network Operations – In 2009, we built upon operational improvements achieved during 2008 by significantly improving the fluidity and efficiency of our transportation network, setting records in numerous operational metrics, including velocity, average terminal dwell, freight car utilization and service delivery. Lower volume levels, network management initiatives, and efforts to improve asset utilization were key drivers of our operational improvement. We increased average train speed by 16% and improved car utilization by 8% with ongoing enhancements to our transportation plan and continued efforts to improve train processing at our terminals. In 2009, customer satisfaction improved to record levels, surpassing records established in 2008, an indication that our ongoing efforts to improve operations again translated into better customer service.

12

• Asset Utilization – In response to economic conditions and lower revenue in 2009, we implemented productivity initiatives to improve efficiency and reduce costs, in addition to adjusting our resources to reflect lower demand. Although varying throughout the year, our resource reductions included removing from service approximately 26% of our road locomotives and 18% of our freight car inventory by year end. We also reduced shift levels at most rail facilities and closed or significantly reduced operations in 30 of our 114 principal rail yards. These demand-driven resource adjustments and our productivity initiatives combined to reduce our workforce by 10%.

• Fuel Prices – As the economy worsened during the third and fourth quarters of 2008, fuel prices dropped dramatically, reaching $33.87 per barrel in December 2008, a near five-year low. Throughout 2009, crude oil prices generally increased, ending the year around $80 per barrel. Overall, our average fuel price decreased by 44% in 2009, reducing operating expenses by $1.3 billion compared to 2008. We also reduced our consumption rate by 4% during the year, saving approximately 40 million gallons of fuel. The use of newer, more fuel efficient locomotives; increased use of distributed locomotive power; fuel conservation programs; and improved network operations and asset utilization all contributed to this improvement.

• Free Cash Flow – Cash generated by operating activities totaled $3.2 billion, yielding free cash flow of $515 million in 2009. Free cash flow is defined as cash provided by operating activities, less cash used in investing activities and dividends paid.

Free cash flow is not considered a financial measure under accounting principles generally accepted in the United States (GAAP) by SEC Regulation G and Item 10 of SEC Regulation S-K. We believe free cash flow is important in evaluating our financial performance and measures our ability to generate cash without additional external financings. Free cash flow should be considered in addition to, rather than as a substitute for, cash provided by operating activities. The following table reconciles cash provided by operating activities (GAAP measure) to free cash flow (non-GAAP measure):

Millions of Dollars	2009		2008		2007
Cash provided by operating activities	$	3,204	$	4,044	$	3,248
Cash used in investing activities		(2,145)		(2,738)		(2,397	)
Dividends paid		(544)		(481)		(364	)
Free cash flow	$	515	$	825	$	487

2010 Outlook

• Safety – Operating a safe railroad benefits our employees, our customers, our shareholders, and the public. We will continue using a multi-faceted approach to safety, utilizing technology, risk assessment, quality control, and training, and by engaging our employees. We will continue implementing Total Safety Culture (TSC) throughout our operations. TSC is designed to establish, maintain, reinforce, and promote safe practices among co-workers. This process allows us to identify and implement best practices for employee and operational safety. Reducing grade-crossing incidents is a critical aspect of our safety programs, and we will continue our efforts to maintain, upgrade, and close crossings; install video cameras on locomotives; and educate the public about crossing safety through our own programs, various industry programs, and other activities.

• Transportation Plan – To build upon our success in recent years, we will continue evaluating traffic flows and network logistic patterns, which can be quite dynamic from year-to-year, to identify additional opportunities to simplify operations, remove network variability and improve network efficiency and asset utilization. We plan to adjust manpower and our locomotive and rail car fleets to

13

meet customer needs and put us in a position to handle demand changes. We will also continue utilizing industrial engineering techniques to improve productivity.

• Fuel Prices – Uncertainty about the economy makes fuel price projections difficult, and we could see volatile fuel prices during the year, as they are sensitive to global and U.S. domestic demand, refining capacity, geopolitical issues and events, weather conditions and other factors. To reduce the impact of fuel price on earnings, we will continue to seek recovery from our customers through our fuel surcharge programs and to expand our fuel conservation efforts.

• Capital Plan – In 2010, we plan to make total capital investments of approximately $2.5 billion, including expenditures for PTC, which may be revised if business conditions or new laws or regulations affect our ability to generate sufficient returns on these investments. See further discussion in this Item 7 under Liquidity and Capital Resources – Capital Plan.

• Positive Train Control (PTC) – In response to a legislative mandate to implement PTC by the end of 2015, we expect to spend approximately $200 million during 2010 on the development of PTC. We currently estimate that PTC will cost us approximately $1.4 billion to implement by the end of 2015, in accordance with rules issued by the FRA. This includes costs for installing the new system along our tracks, upgrading locomotives to work with the new system, and adding digital data communication equipment so all the parts of the system can communicate with each other.

• Financial Expectations – We remain cautious about economic conditions but expect volume to increase from 2009 levels. In addition, we anticipate continued pricing opportunities and further productivity improvements.

Freight revenues are revenues generated by transporting freight or other materials from our six commodity groups. Freight revenues vary with volume (carloads) and average revenue per car (ARC). Changes in price, traffic mix and fuel surcharges drive ARC. We provide some of our customers with contractual incentives for meeting or exceeding specified cumulative volumes or shipping to and from specific locations, which we record as a reduction to freight revenues based on the actual or projected future shipments. We recognize freight revenues on a percentage-of-completion basis as freight moves from origin to destination. We allocate freight revenues between reporting periods based on the relative transit time in each reporting period and recognize expenses as we incur them.

Other revenues include revenues earned by our subsidiaries, revenues from our commuter rail operations, and accessorial revenues, 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 other revenues as we perform services or meet contractual obligations.

Freight revenues and volume levels for all six commodity groups decreased during 2009, reflecting continued economic weakness. We experienced the largest volume declines in automotive and industrial products shipments. Lower fuel surcharges due to lower fuel prices also reduced freight revenues in 2009 compared to 2008. ARC decreased 7% during the full year, driven by lower fuel cost recoveries, partially offset by core pricing gains of approximately 5%. Fuel cost recoveries include fuel surcharge revenue and the impact of resetting the base fuel price for certain traffic, which is described below in more detail.

Freight revenues from five of the six commodity groups increased during 2008, with particularly strong growth from agricultural and energy shipments. While revenues generated from chemical and industrial products shipments grew in 2008 compared to 2007, Hurricanes Gustav and Ike reduced shipments of these commodities. Revenues generated from automotive shipments declined versus 2007. Greater fuel cost recoveries and core pricing improvement combined to increase ARC during 2008. The severe economic downturn during the fourth quarter compounded already declining volumes experienced during the first nine months of 2008 due to ongoing weakness in certain market sectors. As a result, we moved fewer intermodal, automotive, industrial products, and chemical shipments, which more than offset volume growth from agricultural and energy shipments.

Our fuel surcharge programs (excluding index-based contract escalators that contain some provision for fuel) generated freight revenues of $605 million, $2.3 billion, and $1.5 billion in 2009, 2008, and 2007, respectively. Declines in both fuel prices and volume levels drove the lower fuel surcharge amounts in 2009. Fuel surcharge revenues are not comparable across years due to implementation of new mileage-based fuel surcharge programs. As disclosed in our 2006 Annual Report on Form 10-K, the STB issued a decision limiting the manner in which U.S. railroads can calculate fuel surcharges on traffic regulated by the STB. In April 2007, we converted regulated traffic, which represents approximately 22% of our current revenue base, to mileage-based fuel surcharge programs. In addition, we continue to convert portions of our non-regulated traffic to mileage-based fuel surcharge programs. At the time of introduction, we also reset the base fuel price at which the new mileage-based fuel surcharges take effect. Resetting the fuel price at which the fuel surcharge begins, in conjunction with rebasing the affected transportation rate to include a portion of what had been in the fuel surcharge, did not materially change our freight revenue as higher base rates offset lower fuel surcharge revenue.

In 2009, other revenues decreased from 2008 due primarily to lower revenues at our subsidiary that brokers intermodal and automotive services. Accessorial revenues also decreased in 2009 reflecting lower volume levels during the year.

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

Agricultural Products – Lower volume and fuel surcharges decreased agricultural freight revenue in 2009 versus 2008. Price improvements partially offset these declines. Lower demand in both export and domestic markets led to fewer shipments of corn and feed grains, down 11% in 2009 compared to 2008. Weaker worldwide demand also reduced export shipments of wheat and food grains in 2009 versus 2008.   Price improvements, fuel surcharges, and volume growth generated higher agricultural freight revenue in 2008 versus 2007. Strong global demand for grain and a weak dollar drove higher shipments of corn and feed grains and shipments of wheat and food grains for 2008. Shipments of ethanol, a grain product used as an alternative fuel and fuel additive, and its co-products (primarily livestock feed) also increased. 2009 Agricultural Revenue  

16

Automotive – Declines in shipments of finished vehicles and auto parts and lower fuel surcharges reduced freight revenue in 2009 compared to 2008. Vehicle shipments were down 35% and parts were down 24%. Core pricing gains partially offset these declines. These volume declines resulted from economic conditions that reduced sales and vehicle production. In addition, two major domestic automotive manufacturers declared bankruptcy in the second quarter of 2009, affecting production levels. Although the federal Car Allowance Rebate System (the “cash for clunkers” program) helped stimulate vehicle sales and shipments in the third quarter of 2009, production cuts and soft demand throughout the year more than offset the program’s benefits. 2009 Automotive Revenue  

Double-digit declines in shipments of both finished vehicles and auto parts drove freight revenue lower in 2008 compared to 2007. Price improvements and fuel surcharges partially offset these lower volumes. The manufacturers experienced poor sales and reduced vehicle production during 2008 due to the recessionary economy, which in turn reduced shipments of finished vehicles and parts. In addition, a major parts supplier strike reduced volume levels compared to 2007. Shipments of finished vehicles decreased 23% in 2008 versus 2007.

Chemicals – Reduced volume and fuel surcharges decreased freight revenue from chemical shipments in 2009 versus 2008. Pricing improvements partially offset these declines. Weak market conditions reduced shipments of industrial chemicals in 2009 compared to 2008, driving volume levels down 16%. High inventories, production curtailments, and delayed purchases combined to reduce fertilizer shipments by 29% in 2009. Additionally, business interruptions resulting from Hurricanes Gustav and Ike lowered volume levels in the third quarter of 2008, contributing to a more favorable year-over-year comparison. 2009 Chemicals Revenue  

Price improvements and increased fuel surcharges drove higher revenue from chemicals shipments during 2008, which were partially offset by a decrease in volume levels compared to 2007. Weak market conditions and business interruptions in chemical producing areas resulting from Hurricanes Gustav and Ike all contributed to lower industrial chemicals shipments. Plastics shipments also declined in part due to the impact of Hurricanes Gustav and Ike.

17

Energy – Lower volume and fuel surcharges reduced freight revenue from energy shipments in 2009 versus 2008. Price increases partially offset these declines. Shipments from the Southern Powder River Basin of Wyoming (SPRB) and the Colorado and Utah mines decreased 14% and 25%, respectively, in 2009 compared to 2008. Continued economic weakness and high coal inventories resulted in reduced demand at our utility customers, resulting in lower volumes. Production problems at the Colorado and Utah mines and the loss of SPRB customer contracts also contributed to the volume declines. 2009 Energy Revenue  

Price increases, fuel surcharges, and higher volume produced revenue growth in 2008 versus 2007. Shipments from the SPRB were up 5% compared to 2007 despite mine flooding and network interruptions caused by extensive flooding in the Midwest in June of 2008. Conversely, shipments from the Colorado and Utah mines were down 4% in 2008 versus 2007, due to mine production problems.

Industrial Products – Reduced volume and fuel surcharges resulted in lower freight revenue from industrial products shipments in 2009 versus 2008. Price improvements partially offset these declines. Weak demand and inventory reductions resulting from the economic downturn drove a 53% decline in steel shipments in 2009 compared to 2008. The continued weakness in the housing market reduced lumber shipments, while surplus production and overall market uncertainty resulted in lower paper and newsprint shipments in 2009 versus 2008. In addition, cement and stone shipments declined during the year due to high inventories and weak commercial and residential construction activity. 2009 Industrial Products Revenue  

Price improvements and fuel surcharges contributed to higher freight revenue in 2008 compared to 2007. Lower volume partially offset these increases. Continued softening of the housing market and weak market conditions resulted in lower lumber shipments. In addition, cement and stone shipments declined due to a weak overall residential and commercial construction market. Business interruptions resulting from the hurricanes also reduced various construction-related shipments, primarily stone. Conversely, we shipped more steel in 2008 than in 2007 as the weak dollar increased the cost of steel imports during most of the year, creating a strong demand for domestic steel.

18

Intermodal – Decreased volumes and fuel surcharges reduced freight revenue from intermodal shipments in 2009 versus 2008. Volume from international traffic decreased 24% in 2009 compared to 2008, reflecting economic conditions, continued weak imports from Asia, and diversions to non-UPRR served ports. Additionally, continued weakness in the domestic housing and automotive sectors translated into weak demand in large sectors of the international intermodal market, which also contributed to the volume decline. Conversely, domestic traffic increased 8% in 2009 compared to 2008. A new contract with Hub Group, Inc., which included additional shipments, was executed in the second quarter of 2009 and more than offset the impact of weak market conditions in the second half of 2009. 2009 Intermodal Revenue  

Price increases and fuel surcharges generated higher revenue in 2008, partially offset by lower volume levels. International traffic declined 11% in 2008, reflecting continued softening of imports from China and the loss of a customer contract. Notably, the peak intermodal shipping season, which usually starts in the third quarter, was particularly weak in 2008. Additionally, continued weakness in domestic housing and automotive sectors translated into weak demand in large sectors of the international intermodal market, which also contributed to lower volumes. Domestic traffic declined 3% in 2008 due to the loss of a customer contract and lower volumes from less-than-truckload shippers. Additionally, the flood-related embargo on traffic in the Midwest during the second quarter hindered intermodal volume levels in 2008.

Mexico Business – Each of our commodity groups include revenue from shipments to and from Mexico. Revenue from Mexico business decreased 26% in 2009 versus 2008 to $1.2 billion. Volume declined in five of our six commodity groups, down 19% in 2009, driven by 32% and 24% reductions in industrial products and automotive shipments, respectively. Conversely, energy shipments increased 9% in 2009 versus 2008, partially offsetting these declines.

Revenue from Mexico business increased 13% to $1.6 billion in 2008 compared to 2007. Price improvements and fuel surcharges contributed to these increases, partially offset by a 4% decline in volume in 2008 compared to 2007.

Operating expenses decreased $3.1 billion in 2009 versus 2008. Our fuel price per gallon declined 44% during the year, decreasing operating expenses by $1.3 billion compared to 2008. Cost savings from lower volume, productivity improvements, and better resource utilization also decreased operating expenses in 2009. In addition, lower casualty expense resulting primarily from improving trends in safety performance decreased operating expenses in the year. Conversely, wage and benefit inflation partially offset these reductions. 2009 Operating Expenses  

Operating expenses increased $981 million in 2008. Our fuel price per gallon rose 39% during the year, increasing operating expenses by $1.1 billion compared to 2007. Wage, benefit, and materials inflation, higher depreciation, and costs associated with the January Cascade mudslide and Hurricanes Gustav and Ike also increased expenses during the year. Cost savings from productivity improvements, better resource utilization, and lower volume helped offset these increases.

Compensation and Benefits – Compensation and benefits include wages, payroll taxes, health and welfare costs, pension costs, other postretirement benefits, and incentive costs. Lower volume and productivity initiatives led to a 10% decline in our workforce in 2009 compared to 2008, saving $516 million during the year. Conversely, general wage and benefit inflation increased expenses, partially offsetting these savings.

Productivity initiatives in all areas, combined with lower volume, led to a 4% decline in our workforce for 2008, saving $227 million compared to 2007. Conversely, general wage and benefit inflation and higher pension and postretirement benefits increased expenses in 2008, partially offsetting these reductions.

Fuel – Fuel includes locomotive fuel and gasoline for highway and non-highway vehicles and heavy equipment. Lower diesel fuel prices, which averaged $1.75 per gallon (including taxes and transportation costs) in 2009 compared to $3.15 per gallon in 2008, reduced expenses by $1.3 billion. Volume, as measured by gross ton-miles, decreased 17% in the year, lowering expenses by $664 million compared to 2008. Our fuel consumption rate improved 4% in 2009, resulting in $147 million of cost savings versus 2008. Newer, more fuel efficient locomotives reflecting locomotive acquisitions in recent years and the impact of a smaller fleet due to storage of some of our older locomotives; increased use of distributed locomotive power; our fuel conservation programs; and improved network operations all drove this improvement. Distributed locomotive power is the practice of distributing locomotives throughout a train rather than positioning all of them in the lead resulting in safer and more efficient train operations.

Diesel fuel prices, which averaged $3.15 per gallon (including taxes and transportation costs) in 2008 compared to $2.27 per gallon in 2007, increased expenses by $1.1 billion. A 4% improvement in our fuel consumption rate resulted in $136 million of cost savings due to the use of newer, more fuel efficient locomotives; our fuel conservation programs; improved network operations; and a shift in commodity mix, primarily due to growth in bulk shipments. Volume, as measured by gross ton-miles, decreased 3% in the year, lowering expenses by $101 million compared to 2007.

Purchased Services and Materials – Purchased services and materials expense includes the costs of services purchased from outside contractors; materials used to maintain the Railroad’s lines, structures, and equipment; 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; and tools and supplies. Contract services expense (including

20

equipment maintenance) decreased $134 million in 2009 versus 2008 due to lower volume levels and a favorable year-over-year comparison due to expenses incurred in 2008 resulting from Hurricanes Gustav and Ike. In addition, lower volume levels drove cost reductions of $55 million in transportation and lodging costs and $27 million in expenses associated with operating jointly owned facilities in 2009 versus 2008. We also performed fewer locomotive and freight car repairs as a result of lower volumes and having portions of these fleets stored, which reduced related materials expenses by $87 million in 2009 versus 2008. Clean-up and restoration expenses related to the Cascade mudslide in January, flooding in the Midwest in June, and the two September hurricanes also increased expenses in 2008, creating a favorable year-over-year comparison.

In 2008, higher contract costs (including restoration costs related to the January Cascade mudslide, June Midwest flooding, and September hurricanes) increased expenses $37 million compared to 2007. Higher material costs for freight car wheel sets during the year and an increase in the number of wheel sets required to repair flood-damaged freight cars also contributed to higher materials expense in 2008. Conversely, rail scrap proceeds associated with our rail replacement program partially offset these increases for the year.

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 2009 versus 2008. Costs also increased $34 million in 2009 due to the restructuring of certain locomotive leases (see further discussion in this Item 7 under Liquidity and Capital Resources – Financing Activities). Lower depreciation rates for rail and other track material partially offset the increases. The lower rates, which became effective January 1, 2009, resulted from longer asset lives as determined by service life studies and reduced track usage (based on lower gross ton-miles).

A higher depreciable asset base, reflecting higher capital spending in recent years, increased depreciation expense in 2008 versus 2007.

Equipment and Other Rents – Equipment and other rents expense primarily includes rental expense that 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. Fewer shipments of industrial products and intermodal containers primarily contributed to the $85 million reduction in our short-term freight car rental expense in 2009 versus 2008. In addition, the restructuring of locomotive leases reduced lease expense by $52 million in 2009 compared to 2008 (see further discussion in this Item 7 under Liquidity and Capital Resources – Financing Activities). Lower lease expense for freight cars, intermodal containers, and fleet vehicles also decreased costs in 2009 versus 2008.

Fewer shipments of finished vehicles, industrial products and intermodal containers reduced our short term freight car rental expense by $62 million in 2008 compared to 2007. Lower lease expense for freight cars, intermodal containers, and locomotives also decreased costs. Conversely, lease expense for fleet vehicles increased costs in 2008 compared to 2007.

Other – Other expenses include personal injury, freight and property damage, insurance, environmental, bad debt, state and local taxes, utilities, telephone and cellular, employee travel, computer software, and other general expenses. Other costs were lower in 2009 compared to 2008 driven by a reduction in personal injury expense (including asbestos-related claims). We completed actuarial studies of personal injury expenses in both the second and fourth quarters of 2009 and 2008 and annual reviews of asbestos-related claims in both years, which resulted in a net reduction of $55 million in casualty expense in 2009 versus 2008. The reduction reflects improvements in our safety experience and lower estimated costs to resolve claims. In addition, the year-over-year comparison was favorably impacted by $28 million due to an adverse development with respect to one claim in 2008 and favorable developments in three cases in 2009. Other costs were also lower in 2009 compared to 2008, driven by a decrease in expenses for freight

21

and property damages, employee travel, and utilities. In addition, higher bad debt expense in 2008 due to the uncertain impact of the recessionary economy drove a favorable year-over-year comparison. Conversely, an additional expense of $30 million related to a transaction with Pacer International, Inc. and higher property taxes partially offset lower costs in 2009.

Other costs were higher in 2008 compared to 2007 due to an increase in bad debts, state and local taxes, loss and damage expenses, utility costs, and other miscellaneous expenses totaling $122 million. Conversely, personal injury costs (including asbestos-related claims) were $8 million lower in 2008 compared to 2007. The reduction reflects improvements in our safety experience and lower estimated costs to resolve claims as indicated in the actuarial studies of our personal injury expense and annual reviews of asbestos-related claims in both 2008 and 2007. The year-over-year comparison also includes the negative impact of adverse development associated with one claim in 2008. In addition, environmental and toxic tort expenses were $7 million lower in 2008 compared to 2007.

Non-Operating Items

Millions of Dollars	2009		2008		2007		% Change 2009 v 2008		% Change 2008 v 2007

Income taxes		(1,084)		(1,316)		(1,150)		(18)		14

Other Income – Other income increased $103 million in 2009 compared to 2008 primarily due to higher gains from real estate sales, which included the $116 million pre-tax gain from a land sale to the Regional Transportation District (RTD) in Colorado and lower interest expense on our sale of receivables program, resulting from lower interest rates and a lower outstanding balance. Reduced rental and licensing income and lower returns on cash investments, reflecting lower interest rates, partially offset these increases.

Other income decreased in 2008 compared to 2007 due to lower gains from real estate sales and decreased returns on cash investments reflecting lower interest rates. Higher rental and licensing income and lower interest expense on our sale of receivables program partially offset the decreases.

Interest Expense – Interest expense increased in 2009 versus 2008 due primarily to higher weighted-average debt levels. In 2009, the weighted-average debt level was $9.6 billion (including the restructuring of locomotive leases in May of 2009), compared to $8.3 billion in 2008. Our effective interest rate was 6.3% in 2009, compared to 6.1% in 2008.

Interest expense increased in 2008 versus 2007 due to a higher weighted-average debt level of $8.3 billion, compared to $7.3 billion in 2007. A lower effective interest rate of 6.1% in 2008, compared to 6.6% in 2007, partially offset the effects of the higher weighted-average debt level.

Income Taxes – Income taxes were lower in 2009 compared to 2008, driven by lower pre-tax income. Our effective tax rate for the year was 36.4% compared to 36.0% in 2008.

Income taxes were higher in 2008 compared to 2007, driven by higher pre-tax income. Our effective tax rates were 36.0% and 38.4% in 2008 and 2007, respectively. The lower effective tax rate in 2008 resulted from several reductions in tax expense related to federal audits and state tax law changes. In addition, the effective tax rate in 2007 was increased by Illinois legislation that increased deferred tax expense in the third quarter of 2007.

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.

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 productivity improvements contributed to 16% and 8% improvements in average train speed in 2009 and 2008, respectively.

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 improves asset utilization and service. Average terminal dwell time improved slightly in 2009 compared to 2008 and improved 1% in 2008 versus 2007. Lower volumes combined with initiatives to more timely deliver rail cars to our interchange partners and customers improved dwell time in both periods.

Gross and Revenue Ton-Miles – Gross ton-miles are calculated by multiplying the weight of loaded and 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 and revenue-ton-miles decreased 17% and 15% in 2009 compared to 2008 due to a 16% decrease in carloads. Commodity mix changes (notably automotive shipments, which were 30% lower in 2009 compared to 2008) drove the difference in declines between gross ton-miles and revenue ton-miles. Gross ton-miles decreased 3%, while revenue ton-miles were flat in 2008 compared to 2007 with commodity mix changes (notably autos and coal) explaining the variance in year over year growth between the two metrics.

Operating Ratio – Operating ratio is defined as our operating expenses as a percentage of operating revenue. Our operating ratios improved 1.3 points to 76.1% in 2009 and 1.9 points to 77.4% in 2008. Core pricing gains, lower fuel prices, network management initiatives, and improved productivity drove the improvement in 2009 and more than offset the 16% volume decline. Price increases, fuel cost recoveries, network management initiatives, and improved productivity drove the improvement in 2008 and more than offset the impact of higher fuel prices.

Employees – Productivity initiatives and lower volumes reduced employee levels 10% throughout the Company in 2009 versus 2008 and 4% in 2008 compared to 2007. Fewer train and engine personnel due

23

to lower volumes and network initiatives, combined with improved productivity within the support organizations, contributed to the lower full-time equivalent force levels.

Customer Satisfaction Index – Our customer satisfaction survey asks customers to rate how satisfied they are with our performance over the last 12 months on a variety of attributes. A higher score indicates higher customer satisfaction. The improvement in survey results in 2009 and 2008 generally reflects customer recognition of our improving service.

ROIC is considered a non-GAAP financial measure by SEC Regulation G and Item 10 of SEC Regulation S-K, and may not be defined and calculated by other companies in the same manner. We believe this measure is important in evaluating the efficiency and effectiveness of the Corporation’s long-term capital investments, and we currently use ROIC as a performance criteria in determining certain elements of equity compensation for our executives. ROIC should be considered in addition to, rather than as a substitute for, other information provided in accordance with GAAP. The most comparable GAAP measure is Return on Average Common Shareholders’ Equity. The tables above provide a reconciliation from return on average common shareholders’ equity to ROIC. Our 2009 ROIC decreased 2.0 points compared to 2008 primarily as a result of lower earnings and higher average debt and equity levels.

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. Operating leases were discounted using 6.3% at December 31, 2009 and 8.0% at December 31, 2008. The lower discount rate reflects changes to interest rates and our current financing costs. 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 tables above provide a reconciliation from debt to capital to adjusted debt to capital. Our December 31, 2009 debt to capital ratios increased as a result of a $921 million net increase in debt from December 31, 2008. Equity at December 31, 2008, was reduced by $704 million for other comprehensive losses. Other comprehensive losses in 2008 were related primarily to pensions. See Note 10 to our consolidated financial statements in Item 8 for more information.

LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 2009, our principal sources of liquidity included cash, cash equivalents, the sale of certain receivables, and our revolving credit facility, as well as the availability of commercial paper and other sources of financing through the capital markets. We had $1.9 billion of committed credit available under our credit facility, with no borrowings outstanding as of December 31, 2009. We did not make any borrowings under this facility during 2009. The value of the outstanding undivided interest held by investors under the sale of receivables program was $400 million as of December 31, 2009. The sale of receivables program is subject to certain requirements, including maintenance of an investment grade bond rating. If our bond rating were to deteriorate, it could have an adverse impact on our liquidity. Access to commercial paper as well as other capital market financings is dependent on market conditions. Deterioration of our operating results or financial condition due to internal or external factors could negatively impact our ability to utilize commercial paper as a source of liquidity. Access to liquidity through the capital markets is also dependent on our financial stability. We expect that we will continue to

25

have access to liquidity by issuing bonds to public or private investors based on our assessment of the current condition of the credit markets.

At December 31, 2009, we had a working capital surplus of approximately $1.0 billion, which reflects our decision to maintain additional cash reserves to enhance liquidity in response to difficult economic conditions. At December 31, 2008, we had a working capital deficit of approximately $100 million. Historically, we have had a working capital deficit, which is common in our industry and does not indicate a lack of liquidity. We maintain adequate resources and, when necessary, have access to capital to meet any daily and short-term cash requirements, and we have sufficient financial capacity to satisfy our current liabilities.

Operating Activities

Lower net income in 2009, a reduction of $184 million in the outstanding balance of our accounts receivable securitization program, higher pension contributions of $72 million, and changes to working capital combined to decrease cash provided by operating activities compared to 2008. Higher net income and changes in working capital combined to increase cash provided by operating activities in 2008 compared to 2007. In addition, accelerated tax deductions enacted in 2008 on certain new operating assets resulted in lower income tax payments in 2008 versus 2007. Voluntary pension contributions in 2008 totaling $200 million and other pension contributions of $8 million partially offset the year-over-year increase versus 2007.

Investing Activities

Lower capital investments and higher proceeds from asset sales drove the decrease in cash used in investing activities in 2009 versus 2008. Increased capital investments and lower proceeds from asset sales drove the increase in cash used in investing activities in 2008 compared to 2007.

Capital Plan – In 2010, we expect our total capital investments to be approximately $2.5 billion, which may be revised if business conditions or new laws or regulations affect our ability to generate sufficient returns on these investments. We expect approximately 73% of our 2010 capital investments will replace and improve existing capital assets. Major investment categories include replacing and improving track infrastructure; increasing network and terminal capacity; improving locomotives and freight cars; improving technology, including investing in PTC; and other capital projects. We expect to fund our 2010 cash capital investments through cash generated from operations, the sale or lease of various operating and non-operating properties, issuance of long-term debt, and cash on hand at December 31, 2009. Our annual capital plan is a critical component of our long-term strategic plan, which we expect will enhance the long-term value of the Corporation for our shareholders by providing sufficient resources to (i) replace and improve our existing track infrastructure to provide safe and fluid operations, (ii) increase network efficiency by adding or improving facilities and track, and (iii) make investments that meet customer demand and take advantage of opportunities for long-term growth.

Financing Activities

Cash used in financing activities decreased in 2009 versus 2008. During 2009 we did not repurchase any shares under our common stock repurchase program, compared to $1.6 billion of repurchases in 2008. Additionally, debt repayments were $337 million lower in 2009, partially offset by lower new debt issuances of $1.4 billion and higher dividend payments (we increased our dividend from $0.22 per share to its current level of $0.27 per share, effective in the third quarter of 2008). The restructuring of equipment leases also generated $87 million in cash consideration, further contributing to the decrease (see further discussion in this Item 7 under Liquidity and Capital Resources – Financing Activities). Cash

27

used in financing activities increased in 2008 versus 2007 due to higher debt repayments of $416 million, an increase of $234 million for the repurchase of common shares (see further discussion of common shares in Market for the Registrant’s Common Equity, Related Stockholder Matters, and Issuer Purchases of Equity Securities - Purchases of Equity Securities Part II, Item 5) and an increase of dividends paid, reflecting a higher quarterly dividend. Higher debt issuances of $676 million partially offset these increases.

Credit Facilities – On December 31, 2009, we had $1.9 billion of credit available under our revolving credit facility (the facility). The facility is designated for general corporate purposes and supports the issuance of commercial paper. We did not draw on the facility during 2009. 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 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 December 31, 2009, and December 31, 2008 (and at all times during these periods), 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 December 31, 2009, the debt-to-net-worth coverage ratio allowed us to carry up to $33.6 billion of debt (as defined in the facility), and we had $10.4 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 (including the Risk Factors in Item 1A of this report) 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. The facility will expire in April 2012 in accordance with its terms, and we currently intend to replace the facility with a substantially similar credit agreement on or before the expiration date, which is consistent with our past practices with respect to our credit facilities.

At December 31, 2009, we had no commercial paper outstanding. Our commercial paper balance is supported by our revolving credit facility but does not reduce the amount of borrowings available under the facility. During 2009, we issued $100 million of commercial paper and repaid $200 million.

At December 31, 2009, we reclassified as long-term debt approximately $320 million of debt due within one year that we intend to refinance. This reclassification reflected our ability and intent to refinance any short-term borrowings and certain current maturities of long-term debt on a long-term basis. At December 31, 2008, we reclassified as long-term debt approximately $400 million of debt due within one year that we intended to refinance at that time.

Ratio of Earnings to Fixed Charges

For each of the years ended December 31, 2009, 2008, and 2007, our ratio of earnings to fixed charges was 4.9, 5.9, and 5.1, respectively. The ratio of earnings to fixed charges was computed on a consolidated basis. Earnings represent income from continuing operations, less equity earnings net of distributions, plus fixed charges and income taxes. Fixed charges represent interest charges, amortization of debt discount, and the estimated amount representing the interest portion of rental charges. See Exhibit 12 to this report for the calculation of the ratio of earnings to fixed charges.

28

Common Shareholders’ Equity

Dividend Restrictions – Our revolving credit facility includes a debt-to-net worth covenant that, under certain circumstances, restricts the payment of cash dividends to our shareholders. The amount of retained earnings available for dividends was $11.6 billion and $10.4 billion at December 31, 2009 and 2008, respectively.

Stock Split – On May 28, 2008, we completed a two-for-one stock split, effected in the form of a 100% stock dividend. The stock split entitled all shareholders of record at the close of business on May 12, 2008, to receive one additional share of our common stock, par value $2.50 per share, for each share of common stock held on that date.

Share Repurchase Program – On January 30, 2007, our Board of Directors authorized the repurchase of up to 40 million shares of Union Pacific Corporation common stock through the end of 2009. On May 1, 2008, our Board of Directors authorized the repurchase of an additional 40 million common shares by March 31, 2011. Management’s assessments of market conditions and other pertinent facts guide the timing and volume of all repurchases. During 2009, we did not repurchase shares under this program. In 2008, we repurchased approximately 22 million shares at an aggregate purchase price of approximately $1.5 billion. These shares were recorded in treasury stock at cost, which includes any applicable commissions and fees. If we elect to make repurchases of our common stock under this program in 2010, we expect to fund such repurchases through cash generated from operations, the sale or lease of various operating and non-operating properties, debt issuances, and cash on hand.

Shelf Registration Statement and Significant New Borrowings – Under our current shelf registration statement, 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. In July 2008, our Board of Directors authorized the issuance of an additional $3 billion of debt securities under our shelf registration. At December 31, 2009, we had remaining authority to issue up to $2.25 billion of debt securities.

During 2009, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
February 20, 2009	$350 million of 5.125% Notes due February 15, 2014
February 20, 2009	$400 million of 6.125% Notes due February 15, 2020

The net proceeds from these offerings were 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.

During the second quarter of 2009, we restructured lease agreements for 813 locomotives resulting in a change in lease classification from operating to capital. As part of the restructuring arrangements, we received $87 million in cash consideration. We recorded capital lease assets of approximately $742 million and related capital lease obligations totaling approximately $843 million. Included in our capital lease obligations is the $87 million in cash consideration and $14 million of accrued operating lease

29

payables that were reclassified as part of our capital lease obligations. Capital lease obligations are reported in our Consolidated Statements of Financial Position as debt.

On October 15, 2009, we entered into a capital lease agreement for 44 locomotives with a total equipment cost of $100 million. The lessor purchased the 44 locomotives from the Corporation and subsequently leased the locomotives back to the Railroad. These capital lease obligations are reported in our Consolidated Statements of Financial Position as debt at December 31, 2009.

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

As described in the notes to the Consolidated Financial Statements and as referenced in the tables below, we have contractual obligations and commercial commitments that may affect our financial condition. 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, other than the risks that we and other similarly situated companies face with respect to the condition of the capital markets (as described in Item 1A of Part II of this report), 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, our commercial obligations, financings, and commitments 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 December 31, 2009:

Off-Balance Sheet Arrangements

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, 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 and $700 million at December 31, 2009 and 2008, respectively. The value of the outstanding undivided interest held by investors under the facility was $400 million and $584 million at December 31, 2009 and 2008, respectively. During 2009, UPRI reduced the outstanding undivided interest held by investors due to a decrease in available receivables. The value of the undivided interest held by investors is not included in our Consolidated Financial Statements. The value of the undivided interest held by investors was supported by $817 million and $1,015 million of accounts receivable held by UPRI at December 31, 2009 and 2008, respectively. At December 31, 2009 and 2008, the value of the interest retained by UPRI was $417 million and $431 million, respectively. This retained interest is included in accounts receivable in our 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 ratios increase one percent, the value of the outstanding undivided interest held by investors would not change as of December 31, 2009. 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 us for these responsibilities. The Railroad collected approximately $13.8 billion and $17.8 billion during the years ended December 31, 2009 and 2008, respectively. UPRI used certain of these proceeds to purchase new receivables under the facility.

The costs of the sale of receivables program are included in other income and were $9 million, $23 million, and $35 million for 2009, 2008, and 2007, respectively. The costs 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 decrease in the 2009 costs was primarily attributable to lower commercial paper rates and a decrease in the outstanding interest held by investors.

31

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.

In August 2009, the sale of receivables facility was renewed for an additional 364-day period at comparable terms and conditions, although the capacity to sell undivided interests was reduced from $700 million to $600 million.

See further discussion in this Item 7 under Other Matters – Accounting Pronouncements for information about recent accounting pronouncements that will have an impact on the accounting treatment of our sale of receivables program.

Guarantees – At December 31, 2009, we were contingently liable for $416 million in guarantees. We have recorded a liability of $3 million and $4 million for the fair value of these obligations as of December 31, 2009 and 2008, 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.

OTHER MATTERS

Inflation – The cumulative effect of long periods of inflation significantly increases asset replacement costs for capital-intensive companies. As a result, assuming that we replace all operating assets at current price levels, depreciation charges (on an inflation-adjusted basis) would be substantially greater than historically reported amounts.

Derivative Financial Instruments – We may use derivative financial instruments in limited instances 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.

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. We manage credit risk related to derivative financial instruments, which is minimal, by requiring high credit standards for counterparties and periodic settlements. At December 31, 2009 and 2008, 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.

Sensitivity Analyses – The sensitivity analyses that follow illustrate the economic effect that hypothetical changes in interest rates could have on our results of operations and financial condition. These hypothetical changes do not consider other factors that could impact actual results.

32

At December 31, 2009, we had variable-rate debt representing approximately 4% of our total debt. If variable interest rates average one percentage point higher in 2010 than our December 31, 2009 variable rate, which was approximately 2%, our interest expense would increase by approximately $4 million. This amount was determined by considering the impact of the hypothetical interest rate on the balances of our variable-rate debt at December 31, 2009.

Market risk for fixed-rate debt is estimated as the potential increase in fair value resulting from a hypothetical one percentage point decrease in interest rates as of December 31, 2009, and amounts to an increase of approximately $774 million to the fair value of our debt at December 31, 2009. We estimated the fair values of our fixed-rate debt by considering the impact of the hypothetical interest rates on quoted market prices and current borrowing rates.

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 as allowed by the Derivatives and Hedging Topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC); therefore, we do not record any ineffectiveness within our Consolidated Financial Statements.

Interest Rate Cash Flow Hedges – We report changes in the fair value of cash flow hedges in accumulated other comprehensive income/loss until the hedged item affects earnings. At December 31, 2009 and 2008, we had reductions of $3 million and $4 million, respectively, recorded as an accumulated other comprehensive income/loss that is being amortized on a straight-line basis through September 30, 2014. As of December 31, 2009 and 2008, we had no interest rate cash flow hedges outstanding.

Accounting Pronouncements – In January 2010, the FASB issued Accounting Standards Update No. 2010-06, Improving Disclosures about Fair Value Measurements. The Update provides amendments to FASB ASC 820-10 that require entities to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers. In addition the Update requires entities to present separately information about purchases, sales, issuances, and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). The disclosures related to Level 1 and Level 2 fair value measurements are effective for us in 2010 and the disclosures related to Level 3 fair value measurements are effective for us in 2011. The Update requires new disclosures only, and will have no impact on our consolidated financial position, results of operations, or cash flows.

In June 2009, the FASB issued Statement No. 166, Accounting for Transfers of Financial Assets—an amendment of FASB Statement No. 140 (FAS 166). FAS 166 limits the circumstances in which transferred financial assets can be derecognized and requires enhanced disclosures regarding transfers of financial assets and a transferor’s continuing involvement with transferred financial assets. In addition, the concept of a qualifying special-purpose entity is no longer relevant for accounting purposes. Therefore, formerly qualifying special-purpose entities (as defined under previous accounting standards) should be evaluated for consolidation by reporting entities on and after the effective date in accordance with the applicable consolidation guidance. FAS 166 will be effective for us beginning in 2010. After adoption, transfers of undivided interests in accounts receivable to investors under our sale of receivables program will no longer qualify for sale treatment, but rather will be accounted for as secured borrowings

33

in our Consolidated Statements of Financial Position. We are still evaluating the impact on our Consolidated Statements of Cash Flows related to the adoption of this standard. The value of the outstanding undivided interest held by investors under our sale of receivables program at December 31, 2009 was $400 million.

In June 2009, the FASB issued Statement No. 167, Amendments to FASB Interpretation No. 46(R) (FAS 167). FAS 167 retains the scope of Interpretation 46(R), Consolidation of Variable Interest Entities, with the addition of entities previously considered qualifying special-purpose entities, as the concept of these entities was eliminated in FASB Statement No. 166, Accounting for Transfers of Financial Assets—an amendment of FASB Statement No. 140. FAS 167 will be effective for us beginning in 2010. The adoption of FAS 167 will not affect our consolidated financial position, results of operations, or cash flows.

In June 2009, the FASB issued Statement No. 168, The FASB Accounting Standards Codification^TMand the Hierarchy of Generally Accepted Accounting Principles—a replacement of FASB Statement No. 162 (FAS 168). The Codification became the source of authoritative GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. On the effective date of FAS 168, the Codification superseded all then-existing non-SEC accounting and reporting standards. All other nongrandfathered non-SEC accounting literature not included in the Codification became nonauthoritative. FAS 168 was effective for financial statements issued for interim and annual periods ending after September 15, 2009. The adoption of FAS 168 did not affect our consolidated financial position, results of operations, or cash flows.

In May 2009, the FASB issued Statement No. 165, Subsequent Events (FAS 165) (codified as FASB ASC 855-10-50). FAS 165 establishes general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. It requires the disclosure of the date through which an entity has evaluated subsequent events and the basis for that date. FAS 165 was effective for interim or annual financial periods ending after June 15, 2009. The adoption of FAS 165 did not affect our consolidated financial position, results of operations, or cash flows.

In April 2009, the FASB issued FSP No. FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments (codified as FASB ASC 820-10-50). This FSP amends FASB Statement No. 107, to require disclosures about fair values of financial instruments for interim reporting periods as well as in annual financial statements. The FSP also amends APB Opinion No. 28 to require those disclosures in summarized financial information at interim reporting periods. This FSP was effective for interim reporting periods ending after June 15, 2009. The adoption of this FSP did not affect our consolidated financial position, results of operations, or cash flows.

In December 2008, the FASB issued FSP FAS 132(R)-1, Employers’ Disclosure about Postretirement Benefit Plan Assets (codified as FASB ASC 715-20-50), which amended Statement 132(R) to require more detailed disclosures about employers’ pension plan assets. New disclosures include more information on investment strategies, major categories of plan assets, concentrations of risk within plan assets and valuation techniques used to measure the fair value of plan assets. This new standard required new disclosures only, and had no impact on our consolidated financial position, results of operations or cash flows. These new disclosures are included in Note 6 to the Consolidated Financial Statements.

Change in Accounting Principle – We historically accounted for rail grinding costs as a capital asset. Effective January 1, 2010, we changed our accounting policy for rail grinding costs from a capitalization method, under which we capitalized the costs of rail grinding and depreciated such capitalized costs, to a direct expense method, under which we expense rail grinding costs as incurred. The expense as incurred method is preferable, as it eliminates the subjectivity in determining the period of benefit associated with

34

rail grinding over which to depreciate the associated capitalized costs. We reflected this change as a change in accounting principle from an acceptable accounting principle to a preferable accounting principle. The application of this preferable accounting principle is presented retrospectively to all periods presented in future earnings releases and in this SEC filing and future SEC filings. When the accounting principle was retrospectively applied, net income for the years ended December 31, 2009, 2008, and 2007 decreased by approximately $8 million, $3 million, and $7 million, or $0.01, $0.01, and $0.02 per share, respectively. This change in accounting principle does not have a material impact on our consolidated financial position, results of operations, or cash flows.

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.

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.

Climate Change – Although climate change could have an adverse impact on our operations and financial performance in the future (see Risk Factors under Item 1A of this report), we are currently unable to predict the manner or severity of such impact. However, we continue to take steps and explore opportunities to reduce the impact of our operations on the environment, including investments in new technologies, using training programs to reduce fuel consumption, and changing our operations to increase fuel efficiency.

CRITICAL ACCOUNTING POLICIES

Our Consolidated Financial Statements have been prepared in accordance with GAAP. The preparation of these financial statements requires estimation and judgment that affect the reported amounts of revenues, expenses, assets, and liabilities. We base our estimates on historical experience and on various other assumptions that we believe are 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. The following critical accounting policies are a subset of our significant accounting policies described in Note 2 to the Financial Statements and Supplementary Data, Item 8. These critical accounting policies affect significant areas of our financial statements and involve judgment and estimates. If these estimates differ significantly from actual results, the impact on our Consolidated Financial Statements may be material.

35

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. 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 13% of the recorded liability related to asserted claims, and approximately 87% related to unasserted claims at December 31, 2009. 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 $545 million to $602 million. We record an accrual at the low end of the range as no amount of loss is more probable than any other. Our personal injury liability activity was as follows:

Millions of Dollars	2009			2008			2007
Beginning balance	$	621		$	593		$	631
Accruals		79			201			165
Payments		(155	)		(173	)		(203	)
Ending balance at December 31	$	545		$	621		$	593
Current portion, ending balance at December 31	$	158		$	186		$	204
Our personal injury claims activity was as follows:
	2009			2008			2007
Open claims, beginning balance		4,079			4,084			4,126
New claims		3,012			3,692			4,133
Settled or dismissed claims		(3,591	)		(3,697	)		(4,175	)
Open claims, ending balance at December 31		3,500			4,079			4,084

Asbestos – We are a defendant in a number of lawsuits in which current and former employees and other parties allege exposure to asbestos. We engage a third party with extensive experience in estimating resolution costs for asbestos-related claims to assist us in assessing our potential liability. 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.

36

Our liability for asbestos-related claims is not discounted to present value due to the uncertainty surrounding the timing of future payments. Approximately 21% of the recorded liability related to asserted claims and approximately 79% related to unasserted claims at December 31, 2009. Because of the uncertainty surrounding the ultimate outcome of asbestos-related claims, it is reasonably possible that future costs to settle these claims may range from approximately $174 million to $189 million. We record an accrual at the low end of the range as no amount of loss is more probable than any other. In conjunction with the liability update performed in 2009, we also reassessed estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2009 and 2008. Our asbestos-related liability activity was as follows:

Millions of Dollars	2009			2008			2007
Beginning balance	$	213		$	265		$	302
Accruals/(credits)		(25	)		(42	)		(20	)
Payments		(14	)		(10	)		(17	)
Ending balance at December 31	$	174		$	213		$	265
Current portion, ending balance at December 31	$	13		$	12		$	11
Our asbestos-related claims activity was as follows:
	2009			2008			2007
Open claims, beginning balance		1,867			2,086			2,277
New claims		249			256			269
Settled or dismissed claims		(446	)		(475	)		(460	)
Open claims, ending balance at December 31		1,670			1,867			2,086

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 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 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 – We are subject to federal, state, and local environmental laws and regulations. We identified 307 sites at which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 32 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.

37

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 we can reasonably estimate such costs. We do not discount our environmental liabilities when the timing of the anticipated cash payments is not fixed or readily determinable. At December 31, 2009, approximately 12% of our environmental liability was discounted at 3.4%, while approximately 13% of our environmental liability was discounted at 3.5% at December 31, 2008. Our environmental liability activity was as follows:

Millions of Dollars	2009			2008			2007
Beginning balance	$	209		$	209		$	210
Accruals		49			46			41
Payments		(41	)		(46	)		(42	)
Ending balance at December 31	$	217		$	209		$	209
Current portion, ending balance at December 31	$	82		$	58		$	63
Our environmental site activity was as follows:
	2009			2008			2007
Open sites, beginning balance		339			339			367
New sites		49			82			72
Closed sites		(81	)		(82	)		(100	)
Open sites, ending balance at December 31		307			339			339

The 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.

Property and Depreciation – Our railroad operations are highly capital intensive, and our large base of homogeneous, network-type assets turns over on a continuous basis. Each year we develop a capital program for the replacement of assets and for the acquisition or construction of assets that enable us to enhance our operations or provide new service offerings to customers. Assets purchased or constructed throughout the year are capitalized if they meet applicable minimum units of property criteria. Properties and equipment are carried at cost and are depreciated on a straight-line basis over their estimated service lives, which are measured in years, except for rail in high-density traffic corridors (i.e., all rail lines except for those subject to abandonment, yard and switching tracks, and electronic yards), which are measured in millions of gross tons per mile of track. We use the group method of depreciation in which all items with similar characteristics, use, and expected life are grouped together in asset classes, and are depreciated using composite depreciation rates. The group method of depreciation treats each asset class as a pool of resources, not as singular items. We currently have more than 60 depreciable asset classes,

38

and we may increase or decrease the number of asset classes due to changes in technology, asset strategies, or other factors.

We determine the estimated service lives of depreciable railroad property by means of depreciation studies. We perform depreciation studies at least every three years for equipment and every six years for track assets (i.e., rail and other track material, ties, and ballast) and other road property. Our depreciation studies take into account the following factors:

• Statistical analysis of historical patterns of use and retirements of each of our asset classes;

• Evaluation of any expected changes in current operations and the outlook for continued use of the assets;

• Evaluation of technological advances and changes to maintenance practices; and

• Expected salvage to be received upon retirement.

For rail in high-density traffic corridors, we measure estimated service lives in millions of gross tons per mile of track. It has been our experience that the lives of rail in high-density traffic corridors are closely correlated to usage (i.e., the amount of weight carried over the rail). The service lives also vary based on rail weight, rail condition, (e.g., new or secondhand), and rail type (e.g., straight or curve). Our depreciation studies for rail in high density traffic corridors consider each of these factors in determining the estimated service lives. For rail in high-density traffic corridors, we calculate depreciation rates annually by dividing the number of gross ton-miles carried over the rail (i.e., the weight of loaded and empty freight cars, locomotives and maintenance of way equipment transported over the rail) by the estimated service lives of the rail measured in millions of gross tons per mile. Rail in high-density traffic corridors accounts for approximately 70 percent of the historical cost of rail and other track material. Based on the number of gross ton-miles carried over our rail in high density traffic corridors during 2009, the estimated service lives of the majority of this rail ranged from 14 years to 30 years. For all other depreciable assets, we compute depreciation based on the estimated service lives of our assets as determined from the analysis of our depreciation studies. Changes in the estimated service lives of our assets and their related depreciation rates are implemented prospectively.

Estimated service lives of depreciable railroad property may vary over time due to changes in physical use, technology, asset strategies, and other factors that will have an impact on the retirement profiles of our assets. We are not aware of any specific factors that are reasonably likely to significantly change the estimated service lives of our assets. Actual use and retirement of our assets may vary from our current estimates, which would impact the amount of depreciation expense recognized in future periods.

Changes in estimated useful lives of our assets due to the results of our depreciation studies could significantly impact future periods’ depreciation expense and have a material impact on our Consolidated Financial Statements. If the estimated useful lives of all depreciable assets were increased by one year, annual depreciation expense would decrease by approximately $43 million. If the estimated useful lives of all depreciable assets were decreased by one year, annual depreciation expense would increase by approximately $46 million. Our recent depreciation studies have resulted in changes in depreciation rates for some asset classes, which did not significantly affect our annual depreciation expense.

Under group depreciation, the historical cost (net of salvage) of depreciable property that is retired or replaced in the ordinary course of business is charged to accumulated depreciation and no gain or loss is recognized. The historical cost of certain track assets is estimated using (i) inflation indices published by the Bureau of Labor Statistics and (ii) the estimated useful life of the assets as determined by our depreciation studies. The indices were selected because they closely correlate with the major costs of the properties comprising the applicable track asset classes. Because of the number of estimates inherent in the depreciation and retirement processes and because it is impossible to precisely estimate each of these variables until a group of property is completely retired, we continually monitor the estimated service

39

lives of our assets and the accumulated depreciation associated with each asset class to ensure our depreciation rates are appropriate.

For retirements of depreciable railroad properties that do not occur in the normal course of business, a gain or loss may be recognized if the retirement meets each of the following three conditions: (i) is unusual, (ii) is material in amount, and (iii) varies significantly from the retirement profile identified through our depreciation studies. During the last three fiscal years, no gains or losses were recognized due to the retirement of depreciable railroad properties. A gain or loss is recognized in other income when we sell land or dispose of assets that are not part of our railroad operations.

Income Taxes – We account for income taxes by recording taxes payable or refundable for the current year and deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. These expected future tax consequences are measured based on current tax law; the effects of future changes in tax laws are not anticipated. Future tax law changes, such as a change in the corporate tax rate, could have a material impact on our financial condition, results of operations, or liquidity. For example, a 1% increase in future income tax rates would increase our deferred tax liability by approximately $280 million.

When appropriate, we record a valuation allowance against deferred tax assets to reflect that these tax assets may not be realized. In determining whether a valuation allowance is appropriate, we consider whether it is more likely than not that all or some portion of our deferred tax assets will not be realized, based on management’s judgments using available evidence about future events. The valuation allowance at December 31, 2009 was $8 million. There was no valuation allowance at December 31, 2008.

At times, we may claim tax benefits that may be challenged by a tax authority. We recognize tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.

Pension and Other Postretirement Benefits – We use third-party actuaries to assist us in properly measuring the liabilities and expenses associated with providing pension and defined contribution medical and life insurance benefits (OPEB) to eligible employees. In order to use actuarial methods to value the liabilities and expenses, we must make several assumptions. The critical assumptions used to measure pension obligations and expenses are the discount rate and expected rate of return on pension assets. For OPEB, the critical assumptions are the discount rate and healthcare cost trend rate.

We evaluate our critical assumptions at least annually, and selected assumptions are based on the following factors:

• Discount rate is based on a Mercer yield curve of high quality corporate bonds (rated AA by a recognized rating agency) for which the timing and amount of cash flows matches our plans’ expected benefit payments.

• Expected return on plan assets is based on our asset allocation mix and our historical return, taking into consideration current and expected market conditions.

• Healthcare cost trend rate is based on our historical rates of inflation and expected market conditions.

40

The following tables present the key assumptions used to measure pension and OPEB expense for 2009 and the estimated impact on 2009 pension and OPEB expense relative to a change in those assumptions:

Assumptions	Pension		OPEB
Discount rate		6.25%		6.25%

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Union Pacific Corporation, its Directors, and Shareholders:

We have audited the accompanying consolidated statements of financial position of Union Pacific Corporation and Subsidiary Companies (the Corporation) as of December 31, 2009 and 2008, and the related consolidated statements of income, changes in common shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2009. Our audits also included the financial statement schedule listed in the Table of Contents at Part IV, Item 15. These financial statements and financial statement schedule are the responsibility of the Corporation’s management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Union Pacific Corporation and Subsidiary Companies as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2009, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

As discussed in Note 3 to the consolidated financial statements, on January 1, 2010, the Corporation changed its method of accounting for rail grinding costs from a capitalization method to a direct expense method. Such change has been retrospectively applied to all years presented.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Corporation’s internal control over financial reporting as of December 31, 2009, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 5, 2010, expressed an unqualified opinion on the Corporation’s internal control over financial reporting.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Union Pacific Corporation and Subsidiary Companies

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. Nature of Operations

Operations and Segmentation – We are a Class I railroad that operates in the United States. We have 32,094 route miles, linking Pacific Coast and Gulf Coast ports with the Midwest and eastern United States gateways and providing several corridors to key Mexican gateways. We serve the western two-thirds of the country and maintain coordinated schedules with other rail carriers for the handling of freight to and from the Atlantic Coast, the Pacific Coast, the Southeast, the Southwest, Canada, and Mexico. Export and import traffic is moved through Gulf Coast and Pacific Coast ports and across the Mexican and Canadian borders.

The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment. Although revenues are 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 revenue by commodity group:

Millions of Dollars	2009		2008		2007
Agricultural		$    2,666		$    3,174		$    2,605
Automotive		854		1,344		1,458
Chemicals		2,102		2,494		2,287
Energy		3,118		3,810		3,134
Industrial Products		2,147		3,273		3,077
Intermodal		2,486		3,023		2,925
Total freight revenues		$    13,373		$    17,118		$    15,486
Other revenues		770		852		797
Total operating revenues		$    14,143		$    17,970		$    16,283

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

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

Subsequent Events Evaluation – We evaluated the effects of all subsequent events through February 5, 2010, the date of this report, which is concurrent with the date we file this report with the U.S. Securities and Exchange Commission (SEC).

2. Significant Accounting Policies

Principles of Consolidation – The Consolidated Financial Statements include the accounts of Union Pacific Corporation and all of its subsidiaries. Investments in affiliated companies (20% to 50% owned) are accounted for using the equity method of accounting. All intercompany transactions are eliminated. We currently have no less than majority-owned investments that require consolidation under variable interest entity requirements.

Cash and Cash Equivalents – Cash equivalents consist of investments with original maturities of three months or less.

Investments – Investments represent our investments in affiliated companies (20% to 50% owned) that are accounted for

under the equity method of accounting and investments in companies (less than 20% owned) accounted for under the cost method of accounting.

Materials and Supplies – Materials and supplies are carried at the lower of average cost or market.

Property and Depreciation – See Note 11.

Impairment of Long-lived Assets – We review long-lived assets, including identifiable intangibles, for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the long-lived assets, the carrying value is reduced to the estimated fair value as measured by the discounted cash flows.

Revenue Recognition – We recognize freight revenues on a percentage-of-completion basis as freight moves from origin to destination. The allocation of revenue between reporting periods is based on the relative transit time in each reporting period with expenses recognized as incurred. Other revenues are recognized as service is performed or contractual obligations are met. Customer incentives, which are primarily provided for shipping a specified cumulative volume or shipping to/from specific locations, are recorded as a reduction to operating revenues based on actual or projected future customer shipments.

Translation of Foreign Currency – Our portion of the assets and liabilities related to foreign investments are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. Revenue and expenses are translated at the average rates of exchange prevailing during the year. Unrealized gains or losses are reflected within common shareholders’ equity as accumulated other comprehensive income or loss.

Financial Instruments – The carrying value of our non-derivative financial instruments approximates fair value. The fair value of our derivative financial instruments is generally determined by reference to market values as quoted by recognized dealers or developed based upon the present value of expected future cash flows.

We periodically use derivative financial instruments, for other than trading purposes, to manage risk related to changes in fuel prices and interest rates.

50

Fair Value Measurements – We use a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. These levels include:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

We have applied fair value measurements to our pension plan assets (see Note 6) and to our interest rate fair value hedges (see Note 13).

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 vest.

We measure and recognize compensation expense for all stock-based awards made to employees and directors, including stock options. Compensation expense is based on the calculated fair value of the awards as measured at the grant date and is expensed ratably over the service period of the awards (generally the vesting period). The fair value of retention awards is the closing stock price on the date of grant, while the fair value of stock options is determined by using the Black-Scholes option pricing model.

Information regarding stock-based compensation appears in the table below:

Millions of Dollars	2009		2008		2007
Stock-based compensation, before tax:
Stock options	$	19	$	25	$	21
Retention awards		39		40		23
Total stock-based compensation, before tax	$	58	$	65	$	44
Total stock-based compensation, after tax	$	36	$	40	$	27
Excess tax benefits from equity compensation plans	$	10	$	54	$	76

Earnings Per Share – Basic earnings per share are calculated on the weighted-average number of common shares outstanding during each period. Diluted earnings per share include shares issuable upon exercise of outstanding stock options and stock-based awards where the conversion of such instruments would be dilutive.

Use of Estimates – Our Consolidated Financial Statements include estimates and assumptions regarding certain assets, liabilities, revenue, and expenses and the disclosure of certain contingent assets and liabilities. Actual future results may differ from such estimates.

Income Taxes – We account for income taxes by recording taxes payable or refundable for the current year and deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. These expected future tax consequences are measured based on current tax law; the effects of future changes in tax laws are not anticipated. Future

51

tax law changes, such as a change in the corporate tax rate, could have a material impact on our financial condition, results of operations, or liquidity.

When appropriate, we record a valuation allowance against deferred tax assets to reflect that these tax assets may not be realized. In determining whether a valuation allowance is appropriate, we consider whether it is more likely than not that all or some portion of our deferred tax assets will not be realized, based on management’s judgments using available evidence about future events.

At times, we may claim tax benefits that may be challenged by a tax authority. We recognize tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.

Pension and Postretirement Benefits – We incur certain employment-related expenses associated with pensions and postretirement health benefits. In order to measure the expense associated with these benefits, we must make various assumptions including discount rates used to value certain liabilities, expected return on plan assets used to fund these expenses, salary increases, employee turnover rates, anticipated mortality rates, and expected future healthcare costs. The assumptions used by us are based on our historical experience as well as current facts and circumstances. We use third-party actuaries to assist us in properly measuring the expense and liability associated with these benefits.

Personal Injury – The cost of injuries to employees and others on our property 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 properly measuring the expense and liability. Our personal injury liability is discounted to present value using applicable U.S. Treasury rates. Legal fees and incidental costs are expensed as incurred.

Asbestos – We estimate a liability for asserted and unasserted asbestos-related claims based on an assessment of the number and value of those claims. We use an external consulting firm to assist us in properly measuring our potential liability. Our liability for asbestos-related claims is not discounted to present value due to the uncertainty surrounding the timing of future payments. Legal fees and incidental costs are expensed as incurred.

Environmental – When environmental issues have been identified with respect to property currently or formerly owned, leased, or otherwise used in the conduct of our business, we and our consultants perform environmental assessments on such 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. Legal fees and incidental costs are expensed as incurred.

3. Change in Accounting Principle – We historically accounted for rail grinding costs as a capital asset. Effective January 1, 2010, we changed our accounting policy for rail grinding costs from a capitalization method, under which we capitalized the costs of rail grinding and depreciated such capitalized costs, to a direct expense method, under which we expense rail grinding costs as incurred. The expense as incurred method is preferable, as it eliminates the subjectivity in determining the period of benefit associated with rail grinding over which to depreciate the associated capitalized costs. We reflected this change as a change in accounting principle from an acceptable accounting principle to a preferable accounting principle. The application of this preferable accounting principle is presented retrospectively to all periods presented.

52

The effects of the adjustments from 1992 (the year we started capitalizing rail grinding) to January 1, 2008 resulted in an adjustment to decrease net properties, deferred income taxes, and shareholders’ equity by $208 million, $79 million, and $129 million, respectively.

The following tables show the effects of the change in our policy for rail grinding costs on the Consolidated Financial Statements:

4. Stock Split

On May 28, 2008, we completed a two-for-one stock split, effected in the form of a 100% stock dividend. The stock split entitled all shareholders of record at the close of business on May 12, 2008, to receive one additional share of our common stock, par value $2.50 per share, for each share of common stock held on that date. All references to common shares and per share amounts have been restated to reflect the stock split for all periods presented.

5. Stock Options and Other Stock Plans

We have 100,962 options outstanding under the 1993 Stock Option and Retention Stock Plan of Union Pacific Corporation (1993 Plan). There are 7,140 restricted shares outstanding under the 1992 Restricted Stock Plan for Non-Employee Directors of Union Pacific Corporation. We no longer grant options or awards of retention shares and units under these plans.

In April 2000, the shareholders approved the Union Pacific Corporation 2000 Directors Plan (Directors Plan) whereby 1,100,000 shares of our common stock were reserved for issuance to our non-employee directors. Under the Directors Plan, each non-employee director, upon his or her initial election to the Board of Directors, receives a grant of 2,000 shares of retention shares or retention stock units. Prior to December 31, 2007, each non-employee director received annually an option to purchase at fair value a number of shares of our common stock, not to exceed 10,000 shares during any calendar year, determined by dividing 60,000 by 1/3 of the fair market value of one share of our common stock on the date of such Board of Directors meeting, with the resulting quotient rounded up or down to the nearest 50 shares. As of December 31, 2009, 18,000 restricted shares were outstanding under the Directors Plan and 292,000 options were outstanding under the Directors Plan.

The Union Pacific Corporation 2001 Stock Incentive Plan (2001 Plan) was approved by the shareholders in April 2001. The 2001 Plan reserved 24,000,000 shares of our common stock for issuance to eligible employees of the Corporation and its subsidiaries in the form of non-qualified options, incentive stock options, retention shares, stock units, and incentive bonus awards. Non-employee directors were not eligible for awards under the 2001 Plan. As of December 31, 2009, 3,366,230 options were outstanding under the 2001 Plan. We no longer grant any stock options or other stock or unit awards under this plan.

The Union Pacific Corporation 2004 Stock Incentive Plan (2004 Plan) was approved by shareholders in April 2004. The 2004 Plan reserved 42,000,000 shares of our common stock for issuance, plus any shares subject to awards made under the 2001 Plan and the 1993 Plan that were outstanding on April 16, 2004, and became available for regrant pursuant to the terms of the 2004 Plan. Under the 2004 Plan, non-qualified options, stock appreciation rights, retention shares, stock units, and incentive bonus awards may be granted to eligible employees of the Corporation and its subsidiaries. Non-employee directors are not eligible for awards under the 2004 Plan. As of December 31, 2009, 8,939,710 options and 3,778,997 retention shares and stock units were outstanding under the 2004 Plan.

55

Pursuant to the above plans 33,559,150; 36,961,123; and 38,601,728 shares of our common stock were authorized and available for grant at December 31, 2009, 2008, and 2007, respectively.

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 annual weighted-average assumptions used for valuation purposes:

Weighted-Average Assumptions	2009		2008		2007
Risk-free interest rate		1.9%		2.8%		4.9%
Dividend yield		2.3%		1.4%		1.4%
Expected life (years)		5.1		5.3		4.7
Volatility		31.3%		22.2%		20.9%
Weighted-average grant-date fair value of options granted	$	11.33	$	13.35	$	11.19

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 2009 is presented below:

	Shares (thous.)		Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term		Aggregate Intrinsic Value (millions)
Outstanding at January 1, 2009		11,983		$    40.81		5.6 yrs.		$    108
Granted		1,865		47.28		N/A		N/A
Exercised		(1,130)		34.86		N/A		N/A
Forfeited or expired		(19)		57.06		N/A		N/A
Outstanding at December 31, 2009		12,699		$    42.27		5.5 yrs.		$    275
Vested or expected to vest at December 31, 2009		12,599		$    42.19		5.5 yrs.		$    274
Options exercisable at December 31, 2009		9,385		$    38.84		4.4 yrs.		$    235

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 December 31, 2009 are subject to performance or market-based vesting conditions.

56

At December 31, 2009, there was $22 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:

Millions of Dollars	2009		2008		2007
Intrinsic value of stock options exercised		$      29		$      169		$    208
Cash received from option exercises		39		83		132
Treasury shares repurchased for employee payroll taxes		(8)		(28)		(61)
Tax benefit realized from option exercises		11		63		78
Aggregate grant-date fair value of stock options vested		29		21		11

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 2009 were as follows:

	Shares (thous.)		Weighted-Average Grant-Date Fair Value
Nonvested at January 1, 2009		2,015		$    49.39
Granted		988		47.43
Vested		(243)		32.84
Forfeited		(41)		51.58
Nonvested at December 31, 2009		2,719		$    50.13

Retention awards are granted at no cost to the employee or non-employee director and vest over periods lasting up to four years. At December 31, 2009, there was $64 million of total unrecognized compensation expense related to nonvested retention awards, which is expected to be recognized over a weighted-average period of 1.8 years.

Performance Retention Awards – In February 2009, 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 January 2007 and 2008, including using annual return on invested capital (ROIC) as the performance measure. Additionally, a change was made to an underlying assumption used in connection with calculating a component of ROIC. A lower discount rate (an assumed interest rate) will be used in both the numerator and denominator when calculating the present value of our future operating lease payments to reflect changes to interest rates and our financing costs. This rate will be consistent with the methodology used to calculate our adjusted debt-to-capital ratio. We will use this new discount rate to calculate ROIC in connection with determining awards of performance stock units granted in 2009. For performance stock units granted in 2007 and 2008, we will continue calculating ROIC with the methodology and assumptions in effect when the performance stock units were granted. See calculation of ROIC in Management’s Discussion and Analysis of Financial Condition and Results of Operations – Other Operating/Performance and Financial Statistics – Return on Invested Capital as Adjusted (ROIC), Item 7.

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

57

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 2009 grant were as follows:

	2009
Dividend per share per quarter		$    0.27
Risk-free interest rate at date of grant		1.9%

Changes in our performance retention awards during 2009 were as follows:

	Shares (thous.)		Weighted-Average Grant-Date Fair Value
Nonvested at January 1, 2009		873		$    50.70
Granted		449		47.28
Vested		(240)		43.23
Forfeited		(22)		53.86
Nonvested at December 31, 2009		1,060		$    50.88

At December 31, 2009, there was $22 million of total unrecognized compensation expense related to nonvested performance retention awards, which is expected to be recognized over a weighted-average period of 1.3 years. A portion of this expense is subject to achievement of the ROIC levels established for the performance stock unit grants.

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.

Plan Amendment

Effective January 1, 2010, Medicare-eligible retirees who are enrolled in the Union Pacific Retiree Medical Program will receive a contribution to a Health Reimbursement Account, which can be used to pay eligible out-of-pocket medical expenses. The impact of the plan amendment is reflected in the projected benefit obligation (PBO) at December 31, 2009.

Funded Status

We are required by GAAP to separately recognize the overfunded or underfunded status of our pension and OPEB plans as an asset or liability. The funded status represents the difference between the PBO and

58

the fair value of the plan assets. The PBO is the present value of benefits earned to date by plan participants, including the effect of assumed future salary increases. The PBO of the OPEB plan is equal to the accumulated benefit obligation, as the present value of the OPEB liabilities is not affected by salary increases. Plan assets are measured at fair value. We use a December 31 measurement date for plan assets and obligations for all our retirement plans.

Changes in our PBO and plan assets are as follows for the years ended December 31:

Funded Status	Pension				OPEB
Millions of Dollars	2009		2008		2009		2008

Underfunded Accumulated Benefit Obligation – The accumulated benefit obligation (ABO) is the present value of benefits earned to date, assuming no future salary growth. The underfunded accumulated benefit obligation represents the difference between the ABO and the fair value of plan assets. At December 31, 2008, the only pension plan that was underfunded was our non-qualified (supplemental) plan, which is not funded by design. At December 31, 2009, the non-qualified (supplemental) plan ABO was $229 million. The PBO, ABO, and fair value of plan assets for pension plans with accumulated benefit obligations in excess of the fair value of the plan assets were as follows for the years ended December 31:

Underfunded Accumulated Benefit Obligation Millions of Dollars	2009		2008
Projected benefit obligation	$	(2,431)	$	(2,272)
Accumulated benefit obligation	$	(2,389)	$	(2,201)
Fair value of plan assets		2,026		1,543
Underfunded accumulated benefit obligation	$	(363)	$	(658)

The ABO for all defined benefit pension plans was $2.4 billion and $2.2 billion at December 31, 2009 and 2008, respectively.

Assumptions – The weighted-average actuarial assumptions used to determine benefit obligations at December 31:

	Pension				OPEB
Percentages	2009		2008		2009		2008
Discount rate		5.90%		6.25%		5.55%		6.25%
Salary increase		3.45%		3.50%		N/A		N/A
Health care cost trend rate for next year (employees under 65)		N/A		N/A		7.50%		6.60%
Health care cost trend rate for next year (employees over 65)		N/A		N/A		9.10%		9.40%
Ultimate health care cost trend rate		N/A		N/A		4.50%		4.50%
Year ultimate trend rate reached		N/A		N/A		2028		2028

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.

61

The components of our net periodic pension and OPEB cost/(benefit) were as follows for the years ended December 31:

	Pension						OPEB
Millions of Dollars	2009		2008		2007		2009		2008		2007

For 2009 and 2008, the discount rate was based on a Mercer yield curve of high quality corporate bonds with cash flows matching our plans’ expected benefit payments. For 2007, the discount rate was based on a hypothetical portfolio of high quality corporate bonds with cash flows matching our plans’ expected benefit payments. The expected return on plan assets is based on our asset allocation mix and our historical return, taking into account current and expected market conditions. The actual return (loss) on pension plan assets, net of fees, was approximately 23% in 2009, (30)% in 2008, and 9% in 2007.

Assumed healthcare cost trend rates have a significant effect on the expense and liabilities reported for healthcare plans. The assumed healthcare cost trend rate is based on historical rates and expected market conditions. A one-percentage point change in the assumed healthcare cost trend rates would have the following effects on OPEB:

Millions of Dollars	One % pt. Increase		One % pt. Decrease
Effect on total service and interest cost components		$      1		$      (1)
Effect on accumulated benefit obligation		9		(8)

Cash Contributions

The following table details our cash contributions for the qualified pension plan and the benefit payments for the non-qualified and OPEB plans:

	Pension
Millions of Dollars	Qualified		Non-qualified		OPEB
2008		$          208		$        12		$          27
2009		280		13		25

Our policy with respect to funding the qualified plans is to fund at least the minimum required by law and not more than the maximum amount deductible for tax purposes. All contributions made to the qualified pension plans in 2009 were voluntary and were made with cash generated from operations.

The OPEB plans are not funded and are not subject to any minimum regulatory funding requirements. Benefit payments for each year represent claims paid for medical and life insurance, and we anticipate our 2010 OPEB payments will be made from cash generated from operations.

Benefit Payments

The following table details expected benefit payments for the years 2010 through 2019:

Millions of Dollars	Pension		OPEB
2010		$     139		$      28
2011		144		28
2012		149		28
2013		155		28
2014		162		28
Years 2015 -2019		885		130

Asset Allocation Strategy

Our pension plan asset allocation at December 31, 2009 and 2008, and target allocation for 2010, are as follows:

	Target Allocation 2010		Percentage of Plan Assets December 31,
			2009		2008
Equity securities		47% to 63%		61%		68%
Debt securities		30% to 40%		31		23
Real estate		2% to   8%		4		6
Commodities		4% to   6%		4		3
Total				100%		100%

The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to achieve our target of an average long-term rate of return of 8%. While we believe we can achieve a long-term average rate of return of 8%, we cannot be certain that the portfolio will perform to our expectations.

63

Assets are strategically allocated among equity, debt, and other investments in order to achieve a diversification level that dampens fluctuations in investment returns. Asset allocation target ranges for equity, debt, and other portfolios are evaluated at least every three years with the assistance of an independent external consulting firm. Actual asset allocations are monitored monthly, and rebalancing actions are executed at least quarterly, if needed.

The pension plan investments are held in a Master Trust, with The Northern Trust Company. The majority of pension plan assets are invested in equity securities, because equity portfolios have historically provided higher returns than debt and other asset classes over extended time horizons, and are expected to do so in the future. Correspondingly, equity investments also entail greater risks than other investments. Equity risks are balanced by investing a significant portion of the plan’s assets in high quality debt securities. The average credit rating of the debt portfolio exceeded A+ as of December 31, 2009 and 2008. The debt portfolio is also broadly diversified and invested primarily in U.S. Treasury, mortgage, and corporate securities. The weighted-average maturity of the debt portfolio was 12 and 5 years at December 31, 2009 and 2008, respectively. The weighted-average maturity increased significantly in 2009 as a new long-term bond allocation was added to the investment portfolio. This new long-term bond allocation was established primarily to mitigate funding status risk associated with potential interest rate changes.

The investment of pension plan assets in securities issued by Union Pacific is specifically prohibited for both the equity and debt portfolios, other than through index fund holdings.

Fair Value Measurements

The pension plan assets are valued at fair value. The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy.

Temporary Cash Investments – These investments consist of U.S. dollars and foreign currencies held in master trust accounts at The Northern Trust Company. Foreign currencies held are reported in terms of U.S. dollars based on currency exchange rates readily available in active markets. These temporary cash investments are classified as Level 1 investments.

Registered Investment Companies – Registered Investment Companies are mutual funds, unit trusts, and other commingled funds registered with the Securities and Exchange Commission. Mutual fund and unit trust shares are traded actively on public exchanges. The share prices for mutual funds and unit trusts are published at the close of each business day. Holdings of mutual funds and unit trusts are classified as Level 1 investments. Other registered commingled funds are not traded publicly, but the underlying assets (stocks and bonds) held in these funds are traded on active markets and the prices for these assets are readily observable. Holdings in other registered commingled funds are classified as Level 2 investments.

U.S. Government Securities – U.S. Government Securities consist of bills, notes, bonds, and other fixed income securities issued directly by the U.S. Treasury or by government-sponsored enterprises. These assets are valued using a bid evaluation process with bid data provided by independent pricing sources. U.S. Government Securities are classified as Level 2 investments.

Corporate Bonds & Debentures – Corporate bonds and debentures consist of fixed income securities issued by U.S. and non-U.S. corporations. These assets are valued using a bid evaluation process with bid data provided by independent pricing sources. Corporate bonds & debentures are classified as Level 2 investments.

64

Corporate Stock – This investment category consists of common and preferred stock issued by U.S. and non-U.S. corporations. Common and preferred shares are traded actively on exchanges and price quotes for these shares are readily available. Holdings of corporate stock are classified as Level 1 investments.

Venture Capital and Partnerships – This investment category is comprised primarily of interests in limited partnerships that invest in privately-held companies or privately-held real estate assets. Due to the private nature of the partnership investments, pricing inputs are not readily observable. Asset valuations are developed by the general partners that manage the partnerships. These valuations are based on property appraisals, application of public market multiples to private company cash flows, utilization of market transactions that provide valuation information for comparable companies, and other methods. Holdings of limited partnership interests are classified as Level 3 investments.

This category also includes an investment in a limited liability company that invests in publicly-traded convertible securities. The limited liability company investment is a fund that invests in both long and short positions in convertible securities, stocks, and fixed income securities. The underlying securities held by the fund are traded actively on exchanges and price quotes for these investments are readily available. Interest in the limited liability company is classified as a Level 2 investment.

This category also holds a small amount of public securities distributed by the partnerships. These public securities are classified as Level 1 investments.

Real Estate – Most of the real estate investments are partnership interests and are therefore included in the Venture Capital and Partnerships category. This category pertains to the real estate investments held in less commonly used structures such as private real estate investment trusts and pooled separate accounts. Asset valuations for the assets held in these structures are valued in a manner similar to that used for partnership investments. As with the limited partnership interests, the valuations for the holdings in these structures are not based on readily observable inputs. Interests in private real estate investment funds and pooled separate accounts are classified as Level 3 investments.

Common Trust Funds – Common trust funds are comprised of shares or units in commingled funds that are not publicly traded. The underlying assets in these funds (equity securities, fixed income securities, and commodity-related securities) are publicly traded on exchanges and price quotes for the assets held by these funds are readily available. Holdings of common trust funds are classified as Level 2 investments.

Other Investments – The category includes several miscellaneous assets such as commodity hedge fund investments. Some of these investments have directly observable values and are classified as Level 1 investments, but the majority of these investments have valuations that are based on observable inputs and are classified as Level 2 investments.

Other Retirement Programs

Thrift Plan – We provide a defined contribution plan (thrift plan) to eligible non-union employees and make matching contributions to the thrift plan. We match 50 cents for each dollar contributed by employees up to the first six percent of compensation contributed. Our thrift plan contributions were $14 million in 2009, 2008 and 2007.

Railroad Retirement System – All Railroad employees are covered by the Railroad Retirement System (the System). Contributions made to the System are expensed as incurred and amounted to approximately $562 million in 2009, $620 million in 2008, and $616 million in 2007.

66

Collective Bargaining Agreements – Under collective bargaining agreements, we provide certain postretirement healthcare and life insurance benefits for eligible union employees. Premiums under the plans are expensed as incurred and amounted to $48 million in 2009, $49 million in 2008, and $40 million in 2007.

7. Other Income

Other income included the following for the years ended December 31:

Millions of Dollars	2009			2008			2007
Rental income	$	73		$	87		$	68
Net gain on non-operating asset dispositions		162			41			52
Interest income		5			21			50

Non-operating environmental costs and other		(36	)		(34	)		(19	)
Total	$	195		$	92		$	116

In June of 2009, we completed a $118 million sale of land to the Regional Transportation District (RTD) in Colorado, resulting in a $116 million pre-tax gain. The agreement with the RTD involves a 33-mile industrial lead track in Boulder, Colorado.

8. Income Taxes

Components of income tax expense/(benefit) were as follows for the years ended December 31:

Millions of Dollars	2009		2008			2007
Current	$	366	$	771		$	822
Deferred		680		679			350
Unrecognized tax benefits		38		(134	)		(22	)
Total income tax expense	$	1,084	$	1,316		$	1,150

For the years ended December 31, reconciliation between statutory and effective tax rates is as follows:

Tax Rate Percentages	2009		2008		2007
Federal statutory tax rate		35.0 %		35.0  %		35.0  %
State statutory rates, net of federal benefits		3.2		3.0		2.9
Deferred tax adjustments		(0.8)		(0.7)		1.0
Tax credits		(0.8)		(0.9)		(0.6)
Other		(0.2)		(0.4)		0.1
Effective tax rate		36.4  %		36.0  %		38.4  %

In February of 2009, California enacted legislation that changed how corporate taxpayers determine the amount of their income subject to California tax. This change reduced our 2009 deferred tax expense by $14 million.

67

In 2007, the State of Illinois enacted legislation that changed how we determine the amount of our income subject to Illinois tax. This legislation increased our 2007 deferred tax expense by $27 million. In January of 2008, Illinois enacted technical corrections legislation that made additional changes in how we determine the amount of our income subject to Illinois tax. This legislation reduced our 2008 deferred tax expense by $16 million.

Deferred tax assets and liabilities are recorded for the expected future tax consequences of events that are reported in different periods for financial reporting and income tax purposes. The majority of our deferred tax liabilities relate to differences between the tax bases and financial reporting amounts of our land and depreciable property, due to accelerated tax depreciation, revaluation of assets in purchase accounting transactions, and differences in capitalization methods.

Deferred income tax liabilities/(assets) were comprised of the following at December 31:

Millions of Dollars	2009			2008
Net current deferred income tax asset	$	(339	)	$	(276	)
Property		10,419			9,935
State taxes, net of federal benefits		715			665
Other		(90	)		(399	)
Net long-term deferred income tax liabilities		11,044			10,201
Net deferred income tax liability	$	10,705		$	9,925

When appropriate, we record a valuation allowance against deferred tax assets to reflect that these tax assets may not be realized. In determining whether a valuation allowance is appropriate, we consider whether it is more likely than not that all or some portion of our deferred tax assets will not be realized, based on management’s judgments using available evidence about future events. Our total valuation allowance at December 31, 2009 was $8 million. There was no valuation allowance at December 31, 2008.

Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. Unrecognized tax benefits are tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.

68

A reconciliation of changes in unrecognized tax benefits liabilities/(assets) from the beginning to the end of the reporting period is as follows:

Millions of Dollars	2009			2008
Unrecognized tax benefits at January 1	$	26		$	161
Increases for positions taken in current year		18			10
Increases for positions taken in prior years		50			1
Decreases for positions taken in prior years		(28	)		(23	)
Settlements with taxing authorities		(3	)		(55	)
Increases (decreases) for interest and penalties		3			(68	)
Lapse of statutes of limitations		(5	)		-
Unrecognized tax benefits at December 31	$	61		$	26

A portion of our unrecognized tax benefits would, if recognized, reduce our effective tax rate. The remaining unrecognized tax benefits relate to tax positions for which only the timing of the benefit is uncertain. Recognition of these tax benefits would reduce our effective tax rate only through a reduction of accrued interest and penalties. The unrecognized tax benefits that would reduce our effective tax rate are as follows:

Millions of Dollars	2009			2008
Unrecognized tax benefits that would reduce the effective tax rate	$	86		$	79
Unrecognized tax benefits that would not reduce the effective tax rate		(25	)		(53	)
Total unrecognized tax benefits	$	61		$	26

We recognize interest and penalties as part of income tax expense. Total accrued liabilities for interest and penalties were $13 million and $10 million at December 31, 2009 and 2008, respectively. Total interest and penalties recognized as part of income tax expense (benefit) were $(11) million for 2009, $(9) million for 2008, and $3 million for 2007.

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. Some interest calculations remain open back to 1986. 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. The IRS is examining the Corporation’s federal income tax returns for 2007 and 2008. Several state tax authorities are examining our state income tax returns for tax years 2003 through 2006.

We filed interest refund claims in 2007 for years 1986 through 1994, and we received refunds of $12 million in 2008. In 2008, we signed a closing agreement resolving all tax matters at IRS Appeals for tax years 1995 through 1998. In connection with the settlement, in 2008 we paid the IRS $52 million of tax and $67 million of interest. We filed interest refund claims in 2009 for years 1995-1998, and received refunds of $17 million in October of 2009. The audit settlement and interest refund claims had only immaterial effects on our income tax expense for 2008 and 2009.

We expect that our unrecognized tax benefits will increase in the next 12 months as 2010 tax positions are added and we accrue interest. We do not anticipate any significant settlements during 2010; however, it is reasonably possible that some state tax disputes may be resolved, which could reduce unrecognized tax benefits by up to $10 million. Of the $61 million balance at December 31, 2009, $1 million is classified as current in the Consolidated Statement of Financial Position.

9. Earnings Per Share

The following table provides a reconciliation between basic and diluted earnings per share for the years ended December 31:

Millions of Dollars, Except Per Share Amounts	2009		2008		2007
Net income	$	1,890	$	2,335	$	1,848
Weighted-average number of shares outstanding:
Basic		503.0		510.6		531.9
Dilutive effect of stock options		1.5		3.4		4.2
Dilutive effect of retention shares and units		1.3		1.0		0.7
Diluted		505.8		515.0		536.8
Earnings per share – basic	$	3.76	$	4.57	$	3.47
Earnings per share – diluted	$	3.74	$	4.53	$	3.44

Common stock options totaling 4.6 million, 1.0 million, and 0.8 million for 2009, 2008, and 2007, respectively, were excluded from the computation of diluted earnings per share because the exercise prices of these options exceeded the average market price of our common stock for the respective periods, and the effect of their inclusion would be anti-dilutive.

10. Comprehensive Income/(Loss)

Comprehensive income/(loss) was as follows:

Millions of Dollars	2009		2008			2007
Net income	$	1,890	$	2,335		$	1,848
Other comprehensive income/(loss):

Property and Depreciation – Our railroad operations are highly capital intensive, and our large base of homogeneous, network-type assets turns over on a continuous basis. Each year we develop a capital program for the replacement of assets and for the acquisition or construction of assets that enable us to enhance our operations or provide new service offerings to customers. Assets purchased or constructed throughout the year are capitalized if they meet applicable minimum units of property criteria. Properties and equipment are carried at cost and are depreciated on a straight-line basis over their estimated service lives, which are measured in years, except for rail in high-density traffic corridors (i.e., all rail lines except for those subject to abandonment, yard and switching tracks, and electronic yards), which are measured in millions of gross tons per mile of track. We use the group method of depreciation in which all items with similar characteristics, use, and expected life are grouped together in asset classes, and are depreciated using composite depreciation rates. The group method of depreciation treats each asset class as a pool of resources, not as singular items. We currently have more than 60 depreciable asset classes, and we may increase or decrease the number of asset classes due to changes in technology, asset strategies, or other factors.

We determine the estimated service lives of depreciable railroad assets by means of depreciation studies. We perform depreciation studies at least every three years for equipment and every six years for track assets (i.e., rail and other track material, ties, and ballast) and other road property. Our depreciation studies take into account the following factors:

• Statistical analysis of historical patterns of use and retirements of each of our asset classes;

• Evaluation of any expected changes in current operations and the outlook for continued use of the assets;

• Evaluation of technological advances and changes to maintenance practices; and

• Expected salvage to be received upon retirement.

For rail in high-density traffic corridors, we measure estimated service lives in millions of gross tons per mile of track. It has been our experience that the lives of rail in high-density traffic corridors are closely correlated to usage (i.e., the amount of weight carried over the rail). The service lives also vary based on rail weight, rail condition, (e.g., new or secondhand), and rail type (e.g., straight or curve). Our depreciation studies for rail in high density traffic corridors consider each of these factors in determining the estimated service lives. For rail in high-density traffic corridors, we calculate depreciation rates annually by dividing the number of gross ton-miles carried over the rail (i.e., the weight of loaded and empty freight cars, locomotives and maintenance of way equipment transported over the rail) by the estimated service lives of the rail measured in millions of gross tons per mile. For all other depreciable assets, we compute depreciation based on the estimated service lives of our assets as determined from the analysis of our depreciation studies. Changes in the estimated service lives of our assets and their related depreciation rates are implemented prospectively.

Under group depreciation, the historical cost (net of salvage) of depreciable property that is retired or replaced in the ordinary course of business is charged to accumulated depreciation and no gain or loss is recognized. The historical cost of certain track assets is estimated using (i) inflation indices published by the Bureau of Labor Statistics and (ii) the estimated useful life of the assets as determined by our depreciation studies. The indices were selected because they closely correlate with the major costs of the properties comprising the applicable track asset classes. Because of the number of estimates inherent in the depreciation and retirement processes and because it is impossible to precisely estimate each of these variables until a group of property is completely retired, we continually monitor the estimated service lives of our assets and the accumulated depreciation associated with each asset class to ensure our depreciation rates are appropriate.

For retirements of depreciable railroad properties that do not occur in the normal course of business, a gain or loss may be recognized if the retirement meets each of the following three conditions: (i) is

72

unusual, (ii) is material in amount, and (iii) varies significantly from the retirement profile identified through our depreciation studies. A gain or loss is recognized in other income when we sell land or dispose of assets that are not part of our railroad operations.

When we purchase an asset, we capitalize all costs necessary to make the asset ready for its intended use. However, many of our assets are self-constructed. A large portion of our capital expenditures is for replacement of existing road infrastructure assets (program projects), which is typically performed by our employees, and for track line expansion (capacity projects). Costs that are directly attributable or overhead costs that relate directly to capital projects are capitalized. Direct costs that are capitalized as part of self-constructed assets include material, labor, and work equipment. Indirect costs are capitalized if they clearly relate to the construction of the asset. These costs are allocated using appropriate statistical bases.

General and administrative expenditures are expensed as incurred. Normal repairs and maintenance are also expensed as incurred, while costs incurred that extend the useful life of an asset, improve the safety of our operations or improve operating efficiency are capitalized.

Assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease. Amortization expense is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease.

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 interest rate and fuel price movements.

73

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. We manage credit risk related to derivative financial instruments, which is minimal, by requiring high credit standards for counterparties and periodic settlements. At December 31, 2009 and 2008, 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; therefore, we do not record any ineffectiveness within our Consolidated Financial Statements.

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

Millions of Dollars, Except Percentages	2009		2008
Amount of debt hedged	$	250	$	250
Percentage of total debt portfolio		3%		3%
Gross fair value asset position	$	15	$	19

We recognized the fair value as a Level 2 valuation. A Level 2 valuation is defined as observable market-based inputs or unobservable inputs that are corroborated by market data.

Interest Rate Cash Flow Hedges – We report changes in the fair value of cash flow hedges in accumulated other comprehensive income/loss until the hedged item affects earnings. At December 31, 2009 and 2008, we had reductions of $3 million and $4 million, respectively, recorded as an accumulated other comprehensive income/loss that is being amortized on a straight-line basis through September 30, 2014. As of December 31, 2009 and 2008, 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 years ended December 31:

Millions of Dollars	2009		2008		2007
(Increase)/decrease in interest expense from interest rate hedging	$	8	$	1	$	(8)
(Increase)/decrease in fuel expense from fuel derivatives		-		1		(1)
Increase/(decrease) in pre-tax income	$	8	$	2	$	(9)

74

Fair Value of Debt Instruments – The fair value of our short- and long-term debt was estimated using quoted market prices, where available, or current borrowing rates. At December 31, 2009, the fair value of total debt was $10.8 billion, approximately $945 million more than the carrying value. At December 31, 2008, the fair value of total debt was $8.7 billion, approximately $247 million less than the carrying value. At both December 31, 2009 and 2008, approximately $320 million of fixed-rate debt securities contained call provisions that allowed us to retire the debt instruments prior to final maturity, with the payment of fixed call premiums, or in certain cases, at par.

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, 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 and $700 million at December 31, 2009 and 2008, respectively. The value of the outstanding undivided interest held by investors under the facility was $400 million and $584 million at December 31, 2009 and 2008, respectively. During 2009, UPRI reduced the outstanding undivided interest held by investors due to a decrease in available receivables. The value of the undivided interest held by investors is not included in our Consolidated Financial Statements. The value of the undivided interest held by investors was supported by $817 million and $1,015 million of accounts receivable held by UPRI at December 31, 2009 and 2008, respectively. At December 31, 2009 and 2008, the value of the interest retained by UPRI was $417 million and $431 million, respectively. This retained interest is included in accounts receivable in our 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 ratios increase one percent, the value of the outstanding undivided interest held by investors would not change as of December 31, 2009. 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 us for these responsibilities. The Railroad collected approximately $13.8 billion and $17.8 billion during the years ended December 31, 2009 and 2008, respectively. UPRI used certain of these proceeds to purchase new receivables under the facility.

The costs of the sale of receivables program are included in other income and were $9 million, $23 million, and $35 million for 2009, 2008, and 2007, respectively. The costs 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 decrease in the 2009 costs was primarily attributable to lower commercial paper rates and a decrease in the outstanding interest held by investors.

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.

In August 2009, the sale of receivables facility was renewed for an additional 364-day period at comparable terms and conditions, although the capacity to sell undivided interests was reduced from $700 million to $600 million.

See Note 18 to the Consolidated Financial Statements for information about recent accounting pronouncements that will have an impact on the accounting treatment of our sale of receivables program.

14. Debt

Total debt as of December 31, 2009 and 2008, net of interest rate swaps designated as fair value hedges, is summarized below:

Millions of Dollars	2009			2008
Notes and debentures, 3.0% to 7.9% due through 2054 [a]	$	7,277		$	6,934
Capitalized leases, 4.7% to 9.5% due through 2028		2,061			1,270
Equipment obligations, 6.2% to 7.8% due through 2031		219			255
Tax-exempt financings, 2.5% to 5.7% due through 2026		182			185

Floating rate term loan, due through 2013		100			100
Medium-term notes, 9.2% to 10.0% due through 2020		61			61
Mortgage bonds, 4.8% due through 2030		58			58
Other		-			76
Unamortized discount		(110	)		(112	)
Total debt [a]		9,848			8,927
Less current portion		(212	)		(320	)
Total long-term debt	$	9,636		$	8,607

[a] 2009 and 2008 included a write-up of $15 million and $19 million, respectively, due to market value adjustments for debt with qualifying fair value hedges that are recorded on the Consolidated Statements of Financial Position.

Debt Maturities – The following table presents aggregate debt maturities as of December 31, 2009, excluding market value adjustments.

Millions of Dollars
2010	$       532
2011	619
2012	824
2013	775
2014	798
Thereafter	6,300
Total debt	$    9,848

As of December 31, 2009, we have reclassified as long-term debt approximately $320 million 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. At December 31, 2008, we reclassified as long-term debt approximately $400 million of debt due within one year that we intended to refinance at that time.

Mortgaged Properties – Equipment with a carrying value of approximately $3.4 billion and $2.7 billion at December 31, 2009 and 2008, respectively, serves as collateral for capital leases and other types of equipment obligations in accordance with the secured financing arrangements utilized to acquire such railroad equipment.

76

As a result of the merger of Missouri Pacific Railroad Company (MPRR) with and into UPRR on January 1, 1997, and pursuant to the underlying indentures for the MPRR mortgage bonds, UPRR must maintain the same value of assets after the merger in order to comply with the security requirements of the mortgage bonds. As of the merger date, the value of the MPRR assets that secured the mortgage bonds was approximately $6.0 billion. In accordance with the terms of the indentures, this collateral value must be maintained during the entire term of the mortgage bonds irrespective of the outstanding balance of such bonds.

Credit Facilities – On December 31, 2009, we had $1.9 billion of credit available under our revolving credit facility (the facility). The facility is designated for general corporate purposes and supports the issuance of commercial paper. We did not draw on the facility during 2009. 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 us to maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing. At December 31, 2009, and December 31, 2008 (and at all times during these periods), 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 December 31, 2009, the debt-to-net-worth coverage ratio allowed us to carry up to $33.6 billion of debt (as defined in the facility), and we had $10.4 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 (including the Risk Factors in Item 1A of this report) 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. The facility will expire in April 2012 in accordance with its term, and we currently intend to replace the facility with a substantially similar credit agreement on or before the expiration date, which is consistent with our past practices with respect to our credit facilities.

At December 31, 2009, 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. During 2009, we issued $100 million of commercial paper and repaid $200 million.

Dividend Restrictions – Our revolving credit facility includes a debt-to-net worth covenant that, under certain circumstances, restricts the payment of cash dividends to our shareholders. The amount of retained earnings available for dividends was $11.6 billion and $10.4 billion at December 31, 2009 and 2008, respectively.

Shelf Registration Statement and Significant New Borrowings – Under our current shelf registration statement, 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.

77

During 2009, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
February 20, 2009	$350 million of 5.125% Notes due February 15, 2014
February 20, 2009	$400 million of 6.125% Notes due February 15, 2020

The net proceeds from these offerings were 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. At December 31, 2009, we had remaining authority from our Board of Directors to issue up to $2.25 billion of debt securities under our shelf registration.

During the second quarter of 2009, we restructured lease agreements for 813 locomotives resulting in a change in lease classification from operating to capital. As part of the restructuring arrangements, we received $87 million in cash consideration. We recorded capital lease assets of approximately $742 million and related capital lease obligations totaling approximately $843 million. Included in our capital lease obligations is the $87 million in cash consideration and $14 million of accrued operating lease payables that were reclassified as part of our capital lease obligations. Capital lease obligations are reported in our Consolidated Statements of Financial Position as debt.

On October 15, 2009, we entered into a capital lease agreement for 44 locomotives with a total equipment cost of $100 million. The lessor purchased the 44 locomotives from the Corporation and subsequently leased the locomotives back to the Railroad. These capital lease obligations are reported in our Consolidated Statements of Financial Position as debt at December 31, 2009.

78

15. Leases

We lease certain locomotives, freight cars, and other property. The Consolidated Statement of Financial Position as of December 31, 2009 and 2008 included $2,754 million, net of $927 million of accumulated depreciation, and $2,024 million, net of $869 million of accumulated depreciation, respectively, for properties held under capital leases. A charge to income resulting from the depreciation for assets held under capital leases is included within depreciation expense in our Consolidated Statements of Income. Future minimum lease payments for operating and capital leases with initial or remaining non-cancelable lease terms in excess of one year as of December 31, 2009 were as follows:

Millions of Dollars	Operating Leases	Capital Leases
2010	$       576	$       290
2011	570	292
2012	488	247
2013	425	256
2014	352	267
Later years	2,901	1,623
Total minimum lease payments	$    5,312	$    2,975
Amount representing interest	N/A	(914	)
Present value of minimum lease payments	N/A	$    2,061

The majority of capital lease payments relate to locomotives. Rent expense for operating leases with terms exceeding one month was $686 million in 2009, $747 million in 2008, and $810 million in 2007. When cash rental payments are not made on a straight-line basis, we recognize variable rental expense on a straight-line basis over the lease term. Contingent rentals and sub-rentals are not significant.

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 third-party actuaries to assist us in measuring 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 13% of the recorded liability related to asserted claims, and approximately 87% related to

79

unasserted claims at December 31, 2009. 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 $545 million to $602 million. We record an accrual at the low end of the range as no amount of loss is more probable than any other. Our personal injury liability activity was as follows:

Millions of Dollars		2009			2008			2007
Beginning balance	$	621		$	593		$	631
Accruals		79			201			165
Payments		(155	)		(173	)		(203	)
Ending balance at December 31	$	545		$	621		$	593
Current portion, ending balance at December 31	$	158		$	186		$	204

Asbestos – We are a defendant in a number of lawsuits in which current and former employees and other parties allege exposure to asbestos. We engage a third party with extensive experience in estimating resolution costs for asbestos-related claims to assist us in assessing our potential liability. 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 21% of the recorded liability related to asserted claims and approximately 79% related to unasserted claims at December 31, 2009. Because of the uncertainty surrounding the ultimate outcome of asbestos-related claims, it is reasonably possible that future costs to settle these claims may range from approximately $174 million to $189 million. We record an accrual at the low end of the range as no amount of loss is more probable than any other. In conjunction with the liability update performed in 2009, we also reassessed estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2009 and 2008. Our asbestos-related liability activity was as follows:

Millions of Dollars		2009			2008			2007
Beginning balance	$	213		$	265		$	302
Accruals/(credits)		(25	)		(42	)		(20	)
Payments		(14	)		(10	)		(17	)
Ending balance at December 31	$	174		$	213		$	265
Current portion, ending balance at December 31	$	13		$	12		$	11

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 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 also may vary in the future if strategies, activities, and outcomes of asbestos litigation materially change;

80

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 – We are subject to federal, state, and local environmental laws and regulations. We identified 307 sites at which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 32 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 we can reasonably estimate such costs. We do not discount our environmental liabilities when the timing of the anticipated cash payments is not fixed or readily determinable. At December 31, 2009, approximately 12% of our environmental liability was discounted at 3.4%, while approximately 13% of our environmental liability was discounted at 3.5% at December 31, 2008. Our environmental liability activity was as follows:

Millions of Dollars		2009			2008			2007
Beginning balance	$	209		$	209		$	210
Accruals		49			46			41
Payments		(41	)		(46	)		(42	)
Ending balance at December 31	$	217		$	209		$	209
Current portion, ending balance at December 31	$	82		$	58		$	63

The 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 December 31, 2009, we were contingently liable for $416 million in guarantees. We have recorded a liability of $3 million and $4 million for the fair value of these obligations as of December 31, 2009 and 2008, 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

81

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.

17. Share Repurchase Program

On January 30, 2007, our Board of Directors authorized the repurchase of up to 40 million shares of Union Pacific Corporation common stock through the end of 2009. On May 1, 2008, our Board of Directors authorized the repurchase of an additional 40 million common shares by March 31, 2011. As of December 31, 2009, we have repurchased a total of $3 billion of Union Pacific Corporation common stock since the original repurchase plan was authorized. Management’s assessments of market conditions and other pertinent facts guide the timing and volume of all repurchases. If we elect to make repurchases of our common stock under this program in 2010, we expect to fund such repurchases through cash generated from operations, the sale or lease of various operating and non-operating properties, debt issuances, and cash on hand.

	Number of Shares Purchased [a]		Average Price Paid [a]

18. Accounting Pronouncements

In January 2010, the FASB issued Accounting Standards Update No. 2010-06, Improving Disclosures about Fair Value Measurements. The Update provides amendments to FASB ASC 820-10 that require entities to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers. In addition the Update requires entities to present separately information about purchases, sales, issuances, and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). The disclosures related to Level 1 and Level 2 fair value measurements are effective for us in 2010 and the disclosures related to Level 3 fair value measurements are effective for us in 2011. The Update requires new disclosures only, and will have no impact on our consolidated financial position, results of operations, or cash flows.

In June 2009, the FASB issued Statement No. 166, Accounting for Transfers of Financial Assets—an amendment of FASB Statement No. 140 (FAS 166). FAS 166 limits the circumstances in which transferred financial assets can be derecognized and requires enhanced disclosures regarding transfers of financial assets and a transferor’s continuing involvement with transferred financial assets. In addition, the concept of a qualifying special-purpose entity is no longer relevant for accounting purposes. Therefore, formerly qualifying special-purpose entities (as defined under previous accounting standards) should be evaluated for consolidation by reporting entities on and after the effective date in accordance with the applicable consolidation guidance. FAS 166 will be effective for us beginning in 2010. After adoption, transfers of undivided interests in accounts receivable to investors under our sale of receivables

82

program will no longer qualify for sale treatment, but rather will be accounted for as secured borrowings in our Consolidated Statements of Financial Position. We are still evaluating the impact on our Consolidated Statements of Cash Flows related to the adoption of this standard. The value of the outstanding undivided interest held by investors under our sale of receivables program at December 31, 2009 was $400 million.

In June 2009, the FASB issued Statement No. 167, Amendments to FASB Interpretation No. 46(R) (FAS 167). FAS 167 retains the scope of Interpretation 46(R), Consolidation of Variable Interest Entities, with the addition of entities previously considered qualifying special-purpose entities, as the concept of these entities was eliminated in FASB Statement No. 166, Accounting for Transfers of Financial Assets—an amendment of FASB Statement No. 140. FAS 167 will be effective for us beginning in 2010. The adoption of FAS 167 will not affect our consolidated financial position, results of operations, or cash flows.

In June 2009, the FASB issued Statement No. 168, The FASB Accounting Standards Codification^TM and the Hierarchy of Generally Accepted Accounting Principles—a replacement of FASB Statement No. 162 (FAS 168). The Codification became the source of authoritative GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. On the effective date of FAS 168, the Codification superseded all then-existing non-SEC accounting and reporting standards. All other nongrandfathered non-SEC accounting literature not included in the Codification became nonauthoritative. FAS 168 was effective for financial statements issued for interim and annual periods ending after September 15, 2009. The adoption of FAS 168 did not affect our consolidated financial position, results of operations, or cash flows.

In May 2009, the FASB issued Statement No. 165, Subsequent Events (FAS 165) (codified as FASB ASC 855-10-50). FAS 165 establishes general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. It requires the disclosure of the date through which an entity has evaluated subsequent events and the basis for that date. FAS 165 was effective for interim or annual financial periods ending after June 15, 2009. The adoption of FAS 165 did not affect our consolidated financial position, results of operations, or cash flows.

In April 2009, the FASB issued FSP No. FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments (codified as FASB ASC 820-10-50). This FSP amends FASB Statement No. 107, to require disclosures about fair values of financial instruments for interim reporting periods as well as in annual financial statements. The FSP also amends APB Opinion No. 28 to require those disclosures in summarized financial information at interim reporting periods. This FSP was effective for interim reporting periods ending after June 15, 2009. The adoption of this FSP did not affect our consolidated financial position, results of operations, or cash flows.

In December 2008, the FASB issued FSP FAS 132(R)-1, Employers’ Disclosure about Postretirement Benefit Plan Assets (codified as FASB ASC 715-20-50), which amended Statement 132(R) to require more detailed disclosures about employers’ pension plan assets. New disclosures include more information on investment strategies, major categories of plan assets, concentrations of risk within plan assets and valuation techniques used to measure the fair value of plan assets. This new standard required new disclosures only, and had no impact on our consolidated financial position, results of operations or cash flows. These new disclosures are included in Note 6 to the Consolidated Financial Statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Union Pacific Corporation, its Directors, and Shareholders:

We have audited the internal control over financial reporting of Union Pacific Corporation and Subsidiary Companies (the Corporation) as of December 31, 2009, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control Over Financial Reporting (not presented herein). Our responsibility is to express an opinion on the Corporation’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2009 of the Corporation and our report dated February 5, 2010 (October 25, 2010 as to the effects of the change in accounting principle discussed in Note 3), expressed an unqualified opinion on those financial statements and financial statement schedule, and included an explanatory paragraph relating to the change in accounting principle discussed in Note 3 to the consolidated financial statements.
