Fellow Shareholders:

I am happy to report another successful year for Union Pacific in 2014. We set numerous financial records, achieving record earnings per share of $5.75 while improving our operating ratio to a record low 63.5 percent, 2.6 points better than 2013. Our return on invested capital* was an all-time high of 16.2 percent, up 1.5 percentage points year-over-year. As a result, Union Pacific was able to reward its shareholders with increased returns in 2014. We increased our quarterly declared dividend per share twice last year, with total dividends declared for 2014 growing 29 percent compared to the full year 2013. We also repurchased $3.2 billion in Union Pacific shares, a 45 percent increase from 2013. UP’s stock price reached an all-time high in 2014, increasing 42 percent, and outpacing the S&P 500 by 30 percentage points.

Union Pacific handled robust volume growth of 7 percent last year. A record grain harvest and increased frac sand shipments drove particularly strong growth in Agricultural Products and Industrial Products, respectively. Increased international volumes and continued highway-to-rail conversions also drove strong growth in Intermodal. Our Automotive and Coal businesses recorded modest volume gains over 2013, while our Chemicals business was up slightly, as growth in base chemicals more than offset a decline in crude-by-rail shipments during the year.

Throughout the year we maintained our unrelenting focus on safety. We achieved an all-time record low reportable personal injury rate while the reportable rate for rail equipment incidents improved 7 percent over last year. The team has made great progress on our way toward achieving our ultimate goal of an incident free environment. Our commitment to risk reduction, Courage to Care, and Total Safety Culture will continue to lead the way so that every employee returns home safely.

Strong carload growth combined with significant weather disruptions to affect the performance of our network during 2014. Average system velocity, as reported to the AAR, decreased 8 percent and average terminal dwell increased 12 percent when compared to 2013. Throughout 2014 we worked hard to improve the fluidity of our network and the service we provided to our customers. In total, we increased our TE&Y workforce by more than 1,700 employees and added around 800 locomotives, including 261 new units, to our active fleet. We are encouraged by the progress we have made, and remain committed to further improvement.

Our capital program helps ensure we have the resources and network capacity required to handle our current volumes as well as future growth. In total we spent $4.1 billion in 2014, strengthening the franchise. This included $2.3 billion in replacement capital to harden our infrastructure, and to improve the safety and resiliency of our network. In addition, we spent $1.4 billion on service, growth, and productivity initiatives driven by investments in capacity, commercial facilities, and equipment. We also continued to make progress toward completing the federally mandated Positive Train Control project. Going forward, we will continue to focus on generating the strong returns needed to support our ongoing capital investment.

With our extensive geographic coverage, our unparalleled access to Gulf and West Coast ports, and the industry’s best access to Mexico, Union Pacific is well-positioned to compete successfully across a wide variety of business segments. In a dynamic environment, this diversity is a great strength of our franchise, which will enable us to serve the growing markets of tomorrow.

As always, there will be challenges to overcome in the year ahead, but we also see growth opportunities to be realized across many of our business sectors. Efficiency is also a cornerstone of our success, and we will continue to build on the progress we’ve made in improving our network capabilities so we can provide the safe, reliable service our customers expect and deserve.

I could not be more proud of the dedicated men and women of Union Pacific who have worked so hard to achieve our success this past year. I am confident that our team will continue to develop the potential of our strong franchise, enhancing the value proposition for our customers, and providing increasing returns for our shareholders.

OPERATIONS

The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment. Although we provide 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. Additional information regarding our business and operations, including revenue and financial information and data and other information regarding environmental matters, is presented in Risk Factors, Item 1A; Legal Proceedings, Item 3; Selected Financial Data, Item 6; Management’s Discussion and Analysis of Financial Condition and Results of Operations, Item 7; and the Financial Statements and Supplementary Data, Item 8 (which include information regarding revenues, statements of income, and total assets).

Operations – UPRR is a Class I railroad operating in the U.S. We have 31,974 route miles, linking Pacific Coast and Gulf Coast ports with the Midwest and eastern U.S. 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 to move freight to and from the Atlantic Coast, the Pacific Coast, the Southeast, the Southwest, Canada, and Mexico. Export and import traffic moves through Gulf Coast and Pacific Coast ports and across the Mexican and Canadian borders. Our freight traffic consists of bulk, manifest, and premium business. Bulk traffic primarily consists of coal, grain, soda ash, ethanol, rock and crude oil shipped in unit trains – trains transporting a single commodity from one source to one destination. Manifest traffic includes individual carload or less than train-load business involving 2014 Freight Revenue  

commodities such as lumber, steel, paper, food and chemicals. The transportation of finished vehicles, auto parts, intermodal containers and truck trailers are included as part of our premium business. In 2014, we generated freight revenues totaling $22.6 billion from the following six commodity groups:

Agricultural Products – Transportation of grains, commodities produced from these grains, and food and beverage products generated 17% of the Railroad’s 2014 freight revenue. The Company accesses most major grain markets, linking the Midwest and Western U.S. producing areas to export terminals in the Pacific Northwest and Gulf Coast ports, as well as Mexico. We also serve significant domestic markets, including grain processors, animal feeders and ethanol producers in the Midwest, West, South and Rocky Mountain states. Unit trains, which transport a single commodity between producers and export terminals or domestic markets, represent approximately 42% of our agricultural shipments.

Automotive – We are the largest automotive carrier west of the Mississippi River and operate or access over 40 vehicle distribution centers. The Railroad’s extensive franchise serves five vehicle assembly plants and connects to West Coast ports, Mexico gateways and the Gulf of Mexico to accommodate both import and export shipments. In addition to transporting finished vehicles, UPRR provides expedited handling of automotive parts in both boxcars and intermodal containers destined for Mexico, the U.S. and Canada. The automotive group generated 9% of Union Pacific’s freight revenue in 2014.

Chemicals – Transporting chemicals generated 16% of our freight revenue in 2014. The Railroad’s unique franchise serves the chemical producing areas along the Gulf Coast, where roughly 60% of the Company’s chemical business originates, terminates or travels. Our chemical franchise also accesses chemical producers in the Rocky Mountains and on the West Coast. The Company’s chemical shipments include four broad categories: petrochemicals, fertilizer, soda ash, and other. Petrochemicals include industrial chemicals, plastics, and petroleum products, including crude oil and liquid petroleum gases. Currently, these products move primarily to and from the Gulf Coast region. Fertilizer movements originate in the Gulf Coast region, the western U.S. and Canada (through interline access) for delivery to major agricultural users in the Midwest, western U.S., as well as abroad. Soda ash originates in southwestern Wyoming and California, destined for chemical and glass producing markets in North America and abroad. Other shipments include sodium products, phosphorus rock and sulfur.

Coal – Shipments of coal and petroleum coke accounted for 18% of our freight revenue in 2014. The Railroad’s network supports the transportation of coal and petroleum coke to independent and regulated power companies and industrial facilities throughout the U.S. Through interchange gateways and ports, UPRR’s reach extends to eastern U.S. utilities, Mexico, Europe and Asia. Water terminals allow the Railroad to move western U.S. coal east via the Mississippi and Ohio Rivers, as well as the Great Lakes. Export coal moves through West Coast ports to Asia and through the Mississippi River and Houston to Europe. Coal traffic originating in the Southern Powder River Basin (SPRB) area of Wyoming is the largest segment of the Railroad’s coal business.

Industrial Products – Our extensive network facilitates the movement of numerous commodities between thousands of origin and destination points throughout North America. The Industrial Products group consists of several categories, including construction products, minerals, consumer goods, metals,

6

lumber, paper, and other miscellaneous products. In 2014, this group generated 20% of Union Pacific’s total freight revenue. Commercial, residential and governmental infrastructure investments drive shipments of steel, aggregates (cement components), cement and wood products. Oil and gas drilling generates demand for raw steel, finished pipe, frac sand, stone and drilling fluid commodities. Industrial and light manufacturing plants receive steel, nonferrous materials, minerals and other raw materials. Paper and packaging commodities, as well as appliances, move to major metropolitan areas for consumers. Lumber shipments originate primarily in the Pacific Northwest and western Canada and move throughout the U.S. for use in new home construction and repair and remodeling.

Intermodal – Our Intermodal business includes two segments: international and domestic. International business consists of import and export container traffic that mainly passes through West Coast ports served by UPRR’s extensive terminal network. Domestic business includes container and trailer traffic picked up and delivered within North America for intermodal marketing companies (primarily shipper agents and logistics companies), as well as truckload carriers. Less-than-truckload and package carriers with time-sensitive business requirements are also an important part of domestic shipments. Together, international and domestic business generated 20% of UPC’s 2014 freight revenue.

Seasonality – Some of the commodities we carry have peak shipping seasons, reflecting either or both the nature of the commodity (such as certain agricultural and food products that have specific growing and harvesting seasons) and the demand cycle for the commodity (such as intermodal traffic that generally peaks during the third quarter to meet holiday-related demand for consumer goods during the fourth quarter). The peak shipping seasons for these commodities can vary considerably each year depending upon various factors, including the strength of domestic and international economies and currencies and the strength of harvests and market prices for agricultural products. In response to an annual request from the Surface Transportation Board (STB) of the U.S. Department of Transportation (DOT) to all of the Class I railroads operating in the U.S., we submit a publicly available letter during the third quarter detailing our plans for handling traffic during the third and fourth quarters and providing other information requested by the STB.

Working Capital – At December 31, 2014 and 2013, we had a modest working capital surplus, which provides enhanced liquidity. In addition, we believe we have adequate access to capital markets to meet any foreseeable cash requirements, and we have sufficient financial capacity to satisfy our current liabilities.

Competition – We are subject to competition from other railroads, motor carriers, ship and barge operators, and pipelines. Our main railroad competitor is Burlington Northern Santa Fe LLC. Its primary subsidiary, BNSF Railway Company (BNSF), operates parallel routes in many of our main traffic corridors. In addition, we operate in corridors served by other railroads and motor carriers. Motor carrier competition exists for five of our six commodity groups (excluding most coal shipments). Because of the proximity of our routes to major inland and Gulf Coast waterways, barges can be particularly competitive, especially for grain and bulk commodities in certain areas where we operate. In addition to price competition, we face competition with respect to transit times, quality and reliability of service from motor carriers and other railroads. Motor carriers in particular can have an advantage over railroads with respect to transit times and timeliness of service. However, railroads are much more fuel-efficient than trucks, which reduces the impact of transporting goods on the environment and public infrastructure, and we have been making efforts to convert certain truck traffic to rail. Additionally, we must build or acquire and maintain our rail system; trucks and barges are able to use public rights-of-way maintained by public entities. Any of the following could also affect the competitiveness of our transportation services for some or all of our commodities: (i) improvements or expenditures materially increasing the quality or reducing the costs of these alternative modes of transportation, (ii) legislation that eliminates or significantly reduces the size or weight limitations applied to motor carriers, or (iii) legislation or regulatory changes that impose operating restrictions on railroads or that adversely affect the profitability of some or all railroad traffic. For more information regarding risks we face from competition, see the Risk Factors in Item 1A of this report.

Key Suppliers – We depend on two key domestic suppliers of high horsepower locomotives. Due to the capital intensive nature of the locomotive manufacturing business and sophistication of this equipment, potential new suppliers face high barriers of entry into this industry. Therefore, if one of these domestic suppliers discontinues manufacturing locomotives for any reason, including insolvency or bankruptcy, we could experience a significant cost increase and risk reduced availability of the locomotives that are necessary to our operations. Additionally, for a high percentage of our rail purchases, we utilize two steel

7

producers (one domestic and one international) that meet our specifications. Rail is critical for maintenance, replacement, improvement, and expansion of our network and facilities. Rail manufacturing also has high barriers of entry, and, if one of those suppliers discontinues operations for any reason, including insolvency or bankruptcy, we could experience cost increases and difficulty obtaining rail.

Employees – Approximately 85% of our 47,201 full-time-equivalent employees are represented by 14 major rail unions. On January 1, 2015, current labor agreements became subject to modification and we began the current round of negotiations with the unions. Existing agreements remain in effect until new agreements are reached or the Railway Labor Act’s procedures (which include mediation, cooling-off periods, and the possibility of Presidential Emergency Boards and Congressional intervention) are exhausted. Contract negotiations historically continue for an extended period of time and we rarely experience work stoppages while negotiations are pending.

Railroad Security – Our security efforts consist of a wide variety of measures including employee training, engagement with our customers, training of emergency responders, and partnerships with numerous federal, state, and local government agencies. While federal law requires us to protect the confidentiality of our security plans designed to safeguard against terrorism and other security incidents, the following provides a general overview of our security initiatives.

UPRR Security Measures – We maintain a comprehensive security plan designed to both deter and respond to any potential or actual threats as they arise. The plan includes four levels of alert status, each with its own set of countermeasures. We employ our own police force, consisting of more than 200 commissioned and highly-trained officers. Our employees also undergo recurrent security and preparedness training, as well as federally-mandated hazardous materials and security training. We regularly review the sufficiency of our employee training programs. We maintain the capability to move critical operations to back-up facilities in different locations.

We operate an emergency response management center 24 hours a day. The center receives reports of emergencies, dangerous or potentially dangerous conditions, and other safety and security issues from our employees, the public, and law enforcement and other government officials. In cooperation with government officials, we monitor both threats and public events, and, as necessary, we may alter rail traffic flow at times of concern to minimize risk to communities and our operations. We comply with the hazardous materials routing rules and other requirements imposed by federal law. We also design our operating plan to expedite the movement of hazardous material shipments to minimize the time rail cars remain idle at yards and terminals located in or near major population centers. Additionally, in compliance with Transportation Security Agency regulations, we deployed information systems and instructed employees in tracking and documenting the handoff of Rail Security Sensitive Materials with customers and interchange partners.

We also have established a number of our own innovative safety and security-oriented initiatives ranging from various investments in technology to The Officer on the Train program, which provides local law enforcement officers with the opportunity to ride with train crews to enhance their understanding of railroad operations and risks. Our staff of information security professionals continually assesses cyber security risks and implements mitigation programs that evolve with the changing technology threat environment. To date, we have not experienced any material disruption of our operations due to a cyber threat or attack directed at us.

Cooperation with Federal, State, and Local Government Agencies – We work closely on physical and cyber security initiatives with government agencies, including the DOT and the Department of Homeland Security (DHS) as well as local police departments, fire departments, and other first responders. In conjunction with the Association of American Railroads (AAR), we sponsor Ask Rail, a mobile application which provides first responders with secure links to electronic information, including commodity and emergency response information required by emergency personnel to respond to accidents and other situations. We also participate in the National Joint Terrorism Task Force, a multi-agency effort established by the U.S. Department of Justice and the Federal Bureau of Investigation to combat and prevent terrorism.

We work with the Coast Guard, U.S. Customs and Border Protection (CBP), and the Military Transport Management Command, which monitor shipments entering the UPRR rail network at U.S. border crossings and ports. We were the first railroad in the U.S. to be named a partner in CBP’s Customs-

8

Trade Partnership Against Terrorism, a partnership designed to develop, enhance, and maintain effective security processes throughout the global supply chain.

Cooperation with Customers and Trade Associations – Through TransCAER (Transportation Community Awareness and Emergency Response) we work with the AAR, the American Chemistry Council, the American Petroleum Institute, and other chemical trade groups to provide communities with preparedness tools, including the training of emergency responders. In cooperation with the Federal Railroad Administration (FRA) and other interested groups, we are also working to develop additional improvements to tank car design that will further limit the risk of releases of hazardous materials.

GOVERNMENTAL AND ENVIRONMENTAL REGULATION

Governmental Regulation – Our operations are subject to a variety of federal, state, and local regulations, generally applicable to all businesses. (See also the discussion of certain regulatory proceedings in Legal Proceedings, Item 3.)

The operations of the Railroad are also subject to the regulatory jurisdiction of the STB. The STB has jurisdiction over rates charged on certain regulated rail traffic; common carrier service of regulated traffic; freight car compensation; transfer, extension, or abandonment of rail lines; and acquisition of control of rail common carriers. In 2014, the STB continued its efforts to explore whether to expand rail regulation. The STB has requested parties to discuss the STB’s methodology for determining railroad revenue adequacy and the possible use of a revenue adequacy constraint in regulating railroad rates. The STB also held hearings to evaluate the potential impact of expanded reciprocal switching arrangements on railroads. For the past several legislative sessions, proposed bills have been introduced in Congress that aim to alter the regulatory structure of the railroad industry. We will continue to monitor any legislative activity involving rail and transportation regulation and respond accordingly.

The operations of the Railroad also are subject to the regulations of the FRA and other federal and state agencies. On January 12, 2010, the FRA issued initial rules governing installation of Positive Train Control (PTC) by the end of 2015. The final regulation was issued on August 8, 2014. Although still under development, PTC is a collision avoidance technology intended to override engineer controlled locomotives and stop train-to-train and overspeed accidents, misaligned switch derailments, and unauthorized entry to work zones. Following the issuance of the initial rules, the FRA acknowledged that projected costs will exceed projected benefits by a ratio of at least 22 to one, and we estimate that our costs will be higher than those assumed by the FRA. In August 2012, the FRA provided Congress with a status report regarding implementation of PTC. This report indicated that the rail industry will likely achieve only partial deployment of PTC by the current deadline due to significant technical developments, training and deployment, and the delay in issuing the final rule. Through 2014, we have invested approximately $1.6 billion in the development of PTC. The Company is planning to submit its PTC safety plan to the FRA in the second quarter of 2015.

On August 1, 2014, the Pipeline and Hazardous Materials Safety Administration (PHMSA) issued proposed rules concerning the transportation of certain flammable liquids. The proposed rules include a variety of possible measures including tank car standards, speed restrictions, braking system requirements, community notification, and operating restrictions. We, along with others in the rail industry, submitted comments concerning the proposed rules. Railroad operations for the entire industry could be impacted depending on the outcome of the final rules. We will continue to monitor this rulemaking process.

DOT, the Occupational Safety and Health Administration, PHMSA and DHS, along with other federal agencies, have jurisdiction over certain aspects of safety, movement of hazardous materials and hazardous waste, emissions requirements, and equipment standards. The Rail Safety Improvement Act of 2008, among other things, revised hours of service rules for train and certain other railroad employees, mandated implementation of PTC, imposed passenger service requirements, addressed safety at rail crossings, increased the number of safety related employees of the FRA, and increased fines that may be levied against railroads for safety violations. Additionally, various state and local agencies have jurisdiction over disposal of hazardous waste and seek to regulate movement of hazardous materials in ways not preempted by federal law.

Environmental Regulation – We are subject to extensive federal and state environmental statutes and regulations pertaining to public health and the environment. The statutes and regulations are

9

administered and monitored by the Environmental Protection Agency (EPA) and by various state environmental agencies. The primary laws affecting our operations are the Resource Conservation and Recovery Act, regulating the management and disposal of solid and hazardous wastes; the Comprehensive Environmental Response, Compensation, and Liability Act, regulating the cleanup of contaminated properties; the Clean Air Act, regulating air emissions; and the Clean Water Act, regulating waste water discharges.

Information concerning environmental claims and contingencies and estimated remediation costs is set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies – Environmental, Item 7 and Note 18 to the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data.

The information set forth in this Item 1A should be read in conjunction with the rest of the information included in this report, including Management’s Discussion and Analysis of Financial Condition and Results of Operations, Item 7, and Financial Statements and Supplementary Data, Item 8.

We Must Manage Fluctuating Demand for Our Services and Network Capacity – If there is significant demand for our services that exceeds the designed capacity of our network, we may experience network difficulties, including congestion and reduced velocity, that could compromise the level of service we provide to our customers. This level of demand may also compound the impact of weather and weather-related events on our operations and velocity. Although we continue to improve our transportation plan, add capacity, improve operations at our yards and other facilities, and improve our ability to address surges in demand for any reason with adequate resources, we cannot be sure that these measures will fully or adequately address any service shortcomings resulting from demand exceeding our planned capacity. We may experience other operational or service difficulties related to network capacity, dramatic and unplanned fluctuations in demand for rail service with respect to one or more commodities or operating regions, or other events that could negatively impact our operational efficiency, any of which could have a material adverse effect on our results of operations, financial condition, and liquidity. In the event that we experience significant reductions in demand for rail services with respect to one or more commodities, we may experience increased costs associated with resizing our operations, including higher unit operating costs and costs for the storage of locomotives, rail cars, and other equipment; work-force adjustments; and other related activities, which could have a material adverse effect on our results of operations, financial condition, and liquidity.

We Transport Hazardous Materials – We transport certain hazardous materials and other materials, including crude oil, ethanol, and toxic inhalation hazard (TIH) materials, such as chlorine, that pose certain risks in the event of a release or combustion. Additionally, U.S. laws impose common carrier obligations on railroads that require us to transport certain hazardous materials regardless of risk or potential exposure to loss. A rail accident or other incident or accident on our network, at our facilities, or at the facilities of our customers involving the release or combustion of hazardous materials could involve significant costs and claims for personal injury, property damage, and environmental penalties and remediation in excess of our insurance coverage for these risks, which could have a material adverse effect on our results of operations, financial condition, and liquidity.

We Are Subject to Significant Governmental Regulation – We are subject to governmental regulation by a significant number of federal, state, and local authorities covering a variety of health, safety, labor, environmental, economic (as discussed below), and other matters. Many laws and regulations require us to obtain and maintain various licenses, permits, and other authorizations, and we cannot guarantee that we will continue to be able to do so. Our failure to comply with applicable laws and regulations could have a material adverse effect on us. Governments or regulators may change the legislative or regulatory frameworks within which we operate without providing us any recourse to address any adverse effects on our business, including, without limitation, regulatory determinations or rules regarding dispute resolution, business relationships with other railroads, calculation of our cost of capital or other inputs relevant to computing our revenue adequacy, the prices we charge, and costs and expenses. Significant legislative activity in Congress or regulatory activity by the STB could expand regulation of railroad operations and prices for rail services, which could reduce capital spending on our rail network, facilities and equipment and have a material adverse effect on our results of operations, financial condition, and liquidity. As part of the Rail Safety Improvement Act of 2008, rail carriers must currently implement PTC by the end of 2015, which could have a material adverse effect on our ability to make other capital investments. Rail

10

carriers likely will not meet the current mandatory deadline for PTC implementation due to various factors. Additionally, one or more consolidations of Class I railroads could also lead to increased regulation of the rail industry.

We May Be Affected by General Economic Conditions – Prolonged severe adverse domestic and global economic conditions or disruptions of financial and credit markets may affect the producers and consumers of the commodities we carry and may have a material adverse effect on our access to liquidity and our results of operations and financial condition.

We Face Competition from Other Railroads and Other Transportation Providers – We face competition from other railroads, motor carriers, ships, barges, and pipelines. In addition to price competition, we face competition with respect to transit times and quality and reliability of service. While we must build or acquire and maintain our rail system, trucks, barges and maritime operators are able to use public rights-of-way maintained by public entities. Any future improvements or expenditures materially increasing the quality or reducing the cost of alternative modes of transportation, or legislation that eliminates or significantly reduces the burden of the size or weight limitations currently applicable to motor carriers, could have a material adverse effect on our results of operations, financial condition, and liquidity. Additionally, any future consolidation of the rail industry could materially affect the competitive environment in which we operate.

Severe Weather Could Result in Significant Business Interruptions and Expenditures – As a railroad with a vast network, we are exposed to severe weather conditions and other natural phenomena, including earthquakes, hurricanes, fires, floods, mudslides or landslides, extreme temperatures, and significant precipitation. Line outages and other interruptions caused by these conditions can adversely affect our entire rail network and can adversely affect revenue, costs, and liabilities, which could have a material adverse effect on our results of operations, financial condition, and liquidity.

We Rely on Technology and Technology Improvements in Our Business Operations – We rely on information technology in all aspects of our business. If we do not have sufficient capital to acquire new technology or if we are unable to develop or implement new technology such as PTC or the latest version of our transportation control systems, we may suffer a competitive disadvantage within the rail industry and with companies providing other modes of transportation service, which could have a material adverse effect on our results of operations, financial condition, and liquidity. Additionally, if a cyber attack or other event causes significant disruption or failure of one or more of our information technology systems, including computer hardware, software, and communications equipment, we could suffer a significant service interruption, safety failure, security breach, or other operational difficulties, which could have a material adverse impact on our results of operations, financial condition, and liquidity.

We May Be Subject to Various Claims and Lawsuits That Could Result in Significant Expenditures – As a railroad with operations in densely populated urban areas and other cities and a vast rail network, we are exposed to the potential for various claims and litigation related to labor and employment, personal injury, property damage, environmental liability, and other matters. Any material changes to litigation trends or a catastrophic rail accident or series of accidents involving any or all of property damage, personal injury, and environmental liability that exceed our insurance coverage for such risks could have a material adverse effect on our results of operations, financial condition, and liquidity.

We Are Subject to Significant Environmental Laws and Regulations – Due to the nature of the railroad business, our operations are subject to extensive federal, state, and local environmental laws and regulations concerning, among other things, emissions to the air; discharges to waters; handling, storage, transportation, and disposal of waste and other materials; and hazardous material or petroleum releases. We generate and transport hazardous and non-hazardous waste in our operations, and we did so in our former operations. Environmental liability can extend to previously owned or operated properties, leased properties, and properties owned by third parties, as well as to properties we currently own. Environmental liabilities have arisen and may also arise from claims asserted by adjacent landowners or other third parties in toxic tort litigation. We have been and may be subject to allegations or findings that we have violated, or are strictly liable under, these laws or regulations. We currently have certain obligations at existing sites for investigation, remediation and monitoring, and we likely will have obligations at other sites in the future. Liabilities for these obligations affect our estimate based on our experience and, as necessary, the advice and assistance of our consultants. However, actual costs may vary from our estimates due to any or all of several factors, including changes to environmental laws or interpretations of such laws, technological changes affecting investigations and remediation, the

11

participation and financial viability of other parties responsible for any such liability and the corrective action or change to corrective actions required to remediate any existing or future sites. We could incur significant costs as a result of any of the foregoing, and we may be required to incur significant expenses to investigate and remediate known, unknown, or future environmental contamination, which could have a material adverse effect on our results of operations, financial condition, and liquidity.

We May Be Affected by Climate Change and Market or Regulatory Responses to Climate Change – Climate change, including the impact of global warming, could have a material adverse effect on our results of operations, financial condition, and liquidity. Restrictions, caps, taxes, or other controls on emissions of greenhouse gasses, including diesel exhaust, could significantly increase our operating costs. Restrictions on emissions could also affect our customers that (a) use commodities that we carry to produce energy, (b) use significant amounts of energy in producing or delivering the commodities we carry, or (c) manufacture or produce goods that consume significant amounts of energy or burn fossil fuels, including chemical producers, farmers and food producers, and automakers and other manufacturers. Significant cost increases, government regulation, or changes of consumer preferences for goods or services relating to alternative sources of energy or emissions reductions could materially affect the markets for the commodities we carry, which in turn could have a material adverse effect on our results of operations, financial condition, and liquidity. Government incentives encouraging the use of alternative sources of energy could also affect certain of our customers and the markets for certain of the commodities we carry in an unpredictable manner that could alter our traffic patterns, including, for example, the impacts of ethanol incentives on farming and ethanol producers. Finally, we could face increased costs related to defending and resolving legal claims and other litigation related to climate change and the alleged impact of our operations on climate change. Any of these factors, individually or in operation with one or more of the other factors, or other unforeseen impacts of climate change could reduce the amount of traffic we handle and have a material adverse effect on our results of operations, financial condition, and liquidity.

Strikes or Work Stoppages Could Adversely Affect Our Operations – The U.S. Class I railroads are party to collective bargaining agreements with various labor unions. The majority of our employees belong to labor unions and are subject to these agreements. Disputes with regard to the terms of these agreements or our potential inability to negotiate acceptable contracts with these unions could result in, among other things, strikes, work stoppages, slowdowns, or lockouts, which could cause a significant disruption of our operations and have a material adverse effect on our results of operations, financial condition, and liquidity. Additionally, future national labor agreements, or renegotiation of labor agreements or provisions of labor agreements, could compromise our service reliability or significantly increase our costs for health care, wages, and other benefits, which could have a material adverse impact on our results of operations, financial condition, and liquidity.

The Availability of Qualified Personnel Could Adversely Affect Our Operations – Changes in demographics, training requirements, and the availability of qualified personnel could negatively affect our ability to meet demand for rail service. Unpredictable increases in demand for rail services and a lack of network fluidity may exacerbate such risks, which could have a negative impact on our operational efficiency and otherwise have a material adverse effect on our results of operations, financial condition, and liquidity.

We May Be Affected By Fluctuating Fuel Prices – Fuel costs constitute a significant portion of our transportation expenses. Diesel fuel prices can be subject to dramatic fluctuations, and significant price increases could have a material adverse effect on our operating results. Although we currently are able to recover a significant amount of our fuel expenses from our customers through revenue from fuel surcharges, we cannot be certain that we will always be able to mitigate rising or elevated fuel costs through our fuel surcharges. Additionally, future market conditions or legislative or regulatory activities could adversely affect our ability to apply fuel surcharges or adequately recover increased fuel costs through fuel surcharges. As fuel prices fluctuate, our fuel surcharge programs trail such fluctuations in fuel price by approximately two months, and may be a significant source of quarter-over-quarter and year-over-year volatility, particularly in periods of rapidly changing prices. International, political, and economic factors, events and conditions affect the volatility of fuel prices and supplies. Weather can also affect fuel supplies and limit domestic refining capacity. A severe shortage of, or disruption to, domestic fuel supplies could have a material adverse effect on our results of operations, financial condition, and liquidity. Alternatively, lower fuel prices could have a positive impact on the economy by increasing consumer discretionary spending that potentially could increase demand for various consumer products we transport. However, lower fuel prices could have a negative impact on other commodities we

12

transport, such as coal, frac sand and crude oil shipments, which could have a material adverse affect on our results of operations, financial condition, and liquidity.

We Utilize Capital Markets – Due to the significant capital expenditures required to operate and maintain a safe and efficient railroad, we rely on the capital markets to provide some of our capital requirements. We utilize long-term debt instruments, bank financing and commercial paper from time-to-time, and we pledge certain of our receivables. Significant instability or disruptions of the capital markets, including the credit markets, or deterioration of our financial condition due to internal or external factors could restrict or prohibit our access to, and significantly increase the cost of, commercial paper and other financing sources, including bank credit facilities and the issuance of long-term debt, including corporate bonds. A significant deterioration of our financial condition could result in a reduction of our credit rating to below investment grade, which could restrict, or at certain credit levels below investment grade may prohibit us, from utilizing our current receivables securitization facility. This may also limit our access to external sources of capital and significantly increase the costs of short and long-term debt financing.

A Significant Portion of Our Revenue Involves Transportation of Commodities to and from International Markets – Although revenues from our operations are attributable to transportation services provided in the U.S., a significant portion of our revenues involves the transportation of commodities to and from international markets, including Mexico and Southeast Asia, by various carriers and, at times, various modes of transportation. Significant and sustained interruptions of trade with Mexico or countries in Southeast Asia, including China, could adversely affect customers and other entities that, directly or indirectly, purchase or rely on rail transportation services in the U.S. as part of their operations, and any such interruptions could have a material adverse effect on our results of operations, financial condition and liquidity. Any one or more of the following could cause a significant and sustained interruption of trade with Mexico or countries in Southeast Asia: (a) a deterioration of security for international trade and businesses; (b) the adverse impact of new laws, rules and regulations or the interpretation of laws, rules and regulations by government entities, courts or regulatory bodies, including taxing authorities, that affect our customers doing business in foreign countries; (c) any significant adverse economic developments, such as extended periods of high inflation, material disruptions in the banking sector or in the capital markets of these foreign countries, and significant changes in the valuation of the currencies of these foreign countries that could materially affect the cost or value of imports or exports; (d) shifts in patterns of international trade that adversely affect import and export markets; and (e) a material reduction in foreign direct investment in these countries.

We Are Subject to Legislative, Regulatory, and Legal Developments Involving Taxes – Taxes are a significant part of our expenses. We are subject to U.S. federal, state, and foreign income, payroll, property, sales and use, fuel, and other types of taxes. Changes in tax rates, enactment of new tax laws, revisions of tax regulations, and claims or litigation with taxing authorities could result in substantially higher taxes and, therefore, could have a material adverse effect on our results of operations, financial condition, and liquidity.

We Are Dependent on Certain Key Suppliers of Locomotives and Rail – Due to the capital intensive nature and sophistication of locomotive equipment, potential new suppliers face high barriers to entry. Therefore, if one of the domestic suppliers of high horsepower locomotives discontinues manufacturing locomotives for any reason, including bankruptcy or insolvency, we could experience significant cost increases and reduced availability of the locomotives that are necessary for our operations. Additionally, for a high percentage of our rail purchases, we utilize two steel producers (one domestic and one international) that meet our specifications. Rail is critical to our operations for rail replacement programs, maintenance, and for adding additional network capacity, new rail and storage yards, and expansions of existing facilities. This industry similarly has high barriers to entry, and if one of these suppliers discontinues operations for any reason, including bankruptcy or insolvency, we could experience both significant cost increases for rail purchases and difficulty obtaining sufficient rail for maintenance and other projects.

We May Be Affected by Acts of Terrorism, War, or Risk of War – Our rail lines, facilities, and equipment, including rail cars carrying hazardous materials, could be direct targets or indirect casualties of terrorist attacks. Terrorist attacks, or other similar events, any government response thereto, and war or risk of war may adversely affect our results of operations, financial condition, and liquidity. In addition, insurance premiums for some or all of our current coverages could increase dramatically, or certain coverages may not be available to us in the future.

HARRIMAN DISPATCHING CENTER

The Harriman Dispatching Center (HDC), located in Omaha, Nebraska, is our primary dispatching facility. It is linked to regional dispatching and locomotive management facilities at various locations along our network. HDC employees coordinate moves of locomotives and trains, manage traffic and train crews on our network, and coordinate interchanges with other railroads. Approximately 900 employees currently work on-site in the facility. In the event of a disruption of operations at HDC due to a cyber attack, flooding or severe weather or other event, we maintain the capability to conduct critical operations at back-up facilities in different locations.

RAIL FACILITIES

In addition to our track structure, we operate numerous facilities, including terminals for intermodal and other freight; rail yards for building trains (classification yards), switching, storage-in-transit (the temporary storage of customer goods in rail cars prior to shipment) and other activities; offices to administer and manage our operations; dispatching centers to direct traffic on our rail network; crew quarters to house train crews along our network; and shops and other facilities for fueling, maintenance, and repair of locomotives and repair and maintenance of rail cars and other equipment. The following table includes the major yards and terminals on our system:

CAPITAL EXPENDITURES

Our rail network requires significant annual capital investments for replacement, improvement, and expansion. These investments enhance safety, support the transportation needs of our customers, and improve our operational efficiency. Additionally, we add new locomotives and freight cars to our fleet to replace older, less efficient equipment, to support growth and customer demand, and to reduce our impact on the environment through the acquisition of more fuel-efficient and low-emission locomotives.

2014 Capital Program – During 2014, our capital program totaled $4.1 billion. (See the cash capital expenditures table in Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Financial Condition, Item 7.)

2015 Capital Plan – In 2015, we expect our capital plan to be approximately $4.3 billion, which will include expenditures for PTC of approximately $450 million and may include non-cash investments. We may revise our 2015 capital plan if business conditions warrant or if new laws or regulations affect our ability to generate sufficient returns on these investments. (See discussion of our 2015 capital plan in Management’s Discussion and Analysis of Financial Condition and Results of Operations – 2015 Outlook, Item 7.)

OTHER

Equipment Encumbrances – Equipment with a carrying value of approximately $2.8 billion and $2.9 billion at December 31, 2014, and 2013, respectively served as collateral for capital leases and other types of equipment obligations in accordance with the secured financing arrangements utilized to acquire or refinance such railroad equipment.

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.

Environmental Matters – Certain of our properties are subject to federal, state, and local laws and regulations governing the protection of the environment. (See discussion of environmental issues in Business – Governmental and Environmental Regulation, Item 1, and Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies – Environmental, Item  7.)

Item 3. Legal Proceedings

From time to time, we are involved in legal proceedings, claims, and litigation that occur in connection with our business. We routinely assess our liabilities and contingencies in connection with these matters based upon the latest available information and, when necessary, we seek input from our third-party advisors when making these assessments. Consistent with SEC rules and requirements, we describe below material pending legal proceedings (other than ordinary routine litigation incidental to our business), material proceedings known to be contemplated by governmental authorities, other proceedings arising under federal, state, or local environmental laws and regulations (including governmental proceedings involving potential fines, penalties, or other monetary sanctions in excess of $100,000), and such other pending matters that we may determine to be appropriate.

16

ENVIRONMENTAL MATTERS

As previously reported in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, the Illinois Attorney General’s Office notified UPRR on January 14, 2013, that it will seek a penalty against the Railroad for environmental conditions caused by its predecessor at a former locomotive fueling facility in South Pekin, Illinois. This former CNW facility discontinued fueling operations in the early 1980s. Subsequent environmental investigation revealed evidence of fuel releases to soil and groundwater. In January 2007, the State rejected UPRR’s proposed compliance commitment agreement and responded with a notice of intent to pursue legal action. UPRR continued to perform remedial investigations under the supervision of the Illinois EPA. In June 2012, the Illinois EPA approved UPRR’s proposed remedial action plan for the site, consisting of no further action and monitoring for a period of ten years. Subsequently, the State notified UPRR that it would seek to recover a civil penalty, and during early negotiations, it offered to settle its claim for $240,000. UPRR rejected this offer. The State sued UPRR on October 26, 2013, in the Circuit Court for the Tenth Judicial Circuit, Tazewell County, Illinois. Through continued settlement negotiations, the parties have reached a tentative agreement to settle this matter in exchange for a payment by UPRR of $100,000. Final terms for a written agreement are being developed.

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

Information concerning environmental claims and contingencies and estimated remediation costs is set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies – Environmental, Item 7.

OTHER MATTERS

Antitrust Litigation – As we reported in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2007, 20 rail shippers (many of whom are represented by the same law firms) filed virtually identical antitrust lawsuits in various federal district courts against us and four other Class I railroads in the U.S. Currently, UPRR and three other Class I railroads are the named defendants in the lawsuit. The original plaintiff filed the first of these claims in the U.S. District Court in New Jersey on May 14, 2007. The number of complaints reached a total of 30. These suits allege that the named railroads engaged in price-fixing by establishing common fuel surcharges for certain rail traffic.

In addition to suits filed by direct purchasers of rail transportation services, a few of the suits involved plaintiffs alleging that they are or were indirect purchasers of rail transportation and sought to represent a purported class of indirect purchasers of rail transportation services that paid fuel surcharges. These complaints added allegations under state antitrust and consumer protection laws. On November 6, 2007, the Judicial Panel on Multidistrict Litigation ordered that all of the rail fuel surcharge cases be transferred to Judge Paul Friedman of the U.S. District Court in the District of Columbia for coordinated or consolidated pretrial proceedings. Following numerous hearings and rulings, Judge Friedman dismissed the complaints of the indirect purchasers, which the indirect purchasers appealed. On April 16, 2010, the U.S. Court of Appeals for the District of Columbia affirmed Judge Friedman’s ruling dismissing the indirect purchasers’ claims based on various state laws.

With respect to the direct purchasers’ complaint, Judge Friedman conducted a two-day hearing on October 6 and 7, 2010, on the class certification issue and the railroad defendants’ motion to exclude evidence of interline communications. On April 7, 2011, Judge Friedman issued an order deferring any decision on class certification until the Supreme Court issued its decision in the Wal-Mart employment discrimination case.

On June 21, 2012, Judge Friedman issued his decision, which certified a class of plaintiffs with eight named plaintiff representatives. The decision included in the class all shippers that paid a rate-based fuel surcharge to any one of the defendant railroads for rate-unregulated rail transportation from July 1, 2003, through December 31, 2008. This was a procedural ruling, which did not affirm any of the claims asserted by the plaintiffs and does not affect the ability of the railroad defendants to disprove the allegations made by the plaintiffs. On July 5, 2012, the defendant railroads filed a petition with the U.S. Court of Appeals for

17

the District of Columbia requesting that the court review the class certification ruling. On August 28, 2012, a panel of the Circuit Court of the District of Columbia referred the petition to a merits panel of the court to address the issues in the petition and to address whether the district court properly granted class certification. The Circuit Court heard oral arguments on May 3, 2013. On August 9, 2013, the Circuit Court vacated the class certification decision and remanded the case to the district court to reconsider the class certification decision in light of a recent Supreme Court case and incomplete consideration of errors in the expert report of the plaintiffs. On October 31, 2013, Judge Friedman approved a schedule agreed to by all parties for consideration of the class certification issue on remand.

On October 2, 2014, the plaintiffs informed Judge Friedman that their economic expert had a previously undisclosed conflict of interest. Judge Friedman ruled on November 26, 2014, that the plaintiffs may file a supplemental expert report to support their motion for class certification. The plaintiffs must file their supplemental expert report on or before April 1, 2015. The defendant railroads will then have the opportunity to respond to the plaintiffs’ supplement report. Judge Friedman has not yet set a new date to hear oral arguments on plaintiffs’ motion for class certification.

As we reported in our Current Report on Form 8-K, filed on June 10, 2011, the Railroad received a complaint filed in the U.S. District Court for the District of Columbia on June 7, 2011, by Oxbow Carbon & Minerals LLC and related entities (Oxbow). The complaint named the Railroad and one other U.S. Class I Railroad as defendants and alleged that the named railroads engaged in price-fixing and monopolistic practices in connection with fuel surcharge programs and pricing of shipments of certain commodities, including coal and petroleum coke. The complaint sought injunctive relief and payment of damages of over $30 million, and other unspecified damages, including treble damages. Some of the allegations in the complaint were addressed in the existing fuel surcharge litigation referenced above. The complaint also included additional unrelated allegations regarding alleged limitations on competition for shipments of Oxbow’s commodities. Judge Friedman, who presides over the fuel surcharge matter described above, also presides over this matter. On February 26, 2013, Judge Friedman granted the defendants’ motion to dismiss Oxbow’s complaint for failure to state properly a claim under the antitrust laws. However, the dismissal was without prejudice to refile the complaint. Judge Friedman approved a schedule that allowed Oxbow to file a revised complaint, which Oxbow filed on May 1, 2013. The amended complaint alleges that UPRR and one other Class I railroad violated Sections 1 and 2 of the Sherman Antitrust Act and that UPRR also breached a tolling agreement between Oxbow and UPRR. Oxbow claims that it paid more than $50 million in wrongfully imposed fuel surcharges. UPRR and the other railroad filed separate motions to dismiss the Oxbow revised complaint on July 1, 2013. Judge Friedman heard oral arguments on the motions to dismiss filed by UPRR and the other railroad on January 8, 2015.

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

Item 4. Mine Safety Disclosures

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 New York Stock Exchange (NYSE) under the symbol “UNP”. The following table presents the dividends declared and the high and low prices of our common stock for each of the indicated quarters. All amounts are retroactively adjusted to reflect the June 6, 2014 stock split.

At January 30, 2015, there were 881,284,029 shares of common stock outstanding and 32,112 common shareholders of record. On that date, the closing price of the common stock on the NYSE was $117.21. We have paid dividends to our common shareholders during each of the past 115 years. We declared dividends totaling $1,714 million in 2014 and $1,371 million in 2013. On July 31, 2014, we increased the quarterly dividend to $0.50 per share, payable on October 1, 2014, to shareholders of record on August 29, 2014. On February 5, 2015, we increased the quarterly dividend to $0.55 per share, payable on March 30, 2015, to shareholders of record on February 27, 2015. 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 decreased to $15.4 billion at December 31, 2014, from $16.3 billion at December 31, 2013. (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 2015.

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 business segment. Although revenue is analyzed by commodity, we analyze the net financial results of the Railroad as one segment due to the integrated nature of the rail network.

EXECUTIVE SUMMARY

2014 Results

• Safety – During 2014, we continued focusing on safety to reduce risk and eliminate incidents for our employees, our customers and the public. We achieved our best ever reportable personal injury incidents per 200,000 employee-hours of 0.98 and, for the first time, we ended the year below 1.0. In addition, our full year reportable derailment incident per million train miles improved 7%. These results demonstrate our employees’ dedication to our safety initiatives and our employee engagement efforts through Courage to Care, Total Safety Culture, and UP Way (our continuous improvement culture). We finished 2014 with a 5% higher crossing incident rate per million train miles than the year prior. Previous prevention and mitigation efforts for at-grade crossing improvements continue with new approaches planned for 2015 to reduce our exposure to crossing accidents.

• Financial Performance – In 2014, we continued our record-setting financial performance, generating operating income of $8.8 billion, an 18% increase over 2013. Core pricing gains of 2.5%, business demand and productivity, partially offset by costs of running a slower network and inflation, drove this increase. Our operating ratio for 2014 of 63.5% was an all-time best, improving from last year’s operating ratio of 66.1%. Net income of $5.2 billion surpassed our previous milestone set in 2013, translating into earnings of $5.75 per diluted share for 2014.

• Freight Revenues – Our freight revenues grew 9% year-over-year to a record $22.6 billion driven by volume growth along with core pricing gains of 2.5%. Compared to 2013, freight revenues and volume grew in all six commodity groups with double digit growth in Agricultural and Industrial Products. Our fuel surcharge increased 6% versus 2013 driven by volume growth, improved fuel recovery provisions and the lag effect of our programs (surcharges trail fluctuations in fuel price by approximately two months).

• Network Operations – Significant carload growth levels coupled with severe weather affected the performance of our network and the North American rail network as a whole. Average train speed, as reported to the AAR, declined 8% in 2014 compared to 2013, reflecting the 7% volume increase, a major infrastructure project in Fort Worth, Texas and severe weather conditions. Average terminal dwell time increased 12% primarily due to higher volumes and inclement weather.

• Fuel Prices – Our average price per gallon of diesel fuel in 2014 decreased 6% from the average price in 2013, as both crude oil and the conversion spreads between crude oil and diesel declined in 2014. The lower price decreased operating expenses by over $200 million (excluding any impact from year-over-year volume). Our fuel consumption rate, computed as gallons of fuel consumed divided by gross ton-miles, decreased 1% compared to 2013 also lowering fuel expense. These declines were offset by a 7% increase in gross-ton miles, which increased fuel expense.

• Free Cash Flow – Cash generated by operating activities totaled $7.4 billion, yielding free cash flow of $1.5 billion after reductions of $4.2 billion for cash used in investing activities and a 22% increase in dividends paid. 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 U.S. (GAAP) 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 free cash flow is important to management and investors in evaluating our financial performance and measures our ability to

23

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	2014		2013		2012
Cash provided by operating activities	$	7,385	$	6,823	$	6,161
Cash used in investing activities		(4,249)		(3,405)		(3,633)
Dividends paid		(1,632)		(1,333)		(1,146)
Free cash flow	$	1,504	$	2,085	$	1,382

2015 Outlook

• Safety – Operating a safe railroad benefits all our constituents: our employees, customers, shareholders and the communities we serve. We will continue using a multi-faceted approach to safety, utilizing technology, risk assessment, quality control, training and employee engagement, and targeted capital investments. We will continue using and expanding the deployment of Total Safety Culture and Courage to Care throughout our operations, which allows us to identify and implement best practices for employee and operational safety. We will continue our efforts to increase detection of rail defects; improve or close crossings; and educate the public and law enforcement agencies about crossing safety through a combination of our own programs (including risk assessment strategies), industry programs and local community activities across our network.

• Network Operations – In 2015, we will continue to add resources to support growth, improve service, and replenish our surge capability.

• Fuel Prices – With the dramatic drop in fuel prices at the end of 2014, there is even more uncertainty around the projections of fuel prices. We again could see volatile fuel prices during the year, as they are sensitive to global and U.S. domestic demand, refining capacity, geopolitical events, weather conditions and other factors. As prices fluctuate there will be a timing impact on earnings, as our fuel surcharge programs trail fluctuations in fuel price by approximately two months.

Lower fuel prices could have a positive impact on the economy by increasing consumer discretionary spending that potentially could increase demand for various consumer products that we transport. Alternatively, lower fuel prices will likely have a negative impact on other commodities such as coal, frac sand and crude oil shipments.

• Capital Plan – In 2015, we expect our capital plan to be approximately $4.3 billion, including expenditures for PTC and 218 locomotives. The capital plan may be revised if business conditions warrant or if 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.)

• Financial Expectations – We expect the overall U.S. economy to continue to improve at a moderate pace. One of the biggest uncertainties is the outlook for energy markets, which will bring both challenges and opportunities. On balance, we expect to see positive volume growth for 2015 versus the prior year. In the current environment, we expect continued margin improvement driven by continued pricing opportunities, ongoing productivity initiatives and the ability to leverage our resources as we improve the fluidity of our network.

RESULTS OF OPERATIONS

Operating Revenues

Millions	2014		2013		2012		% Change  2014 v 2013		% Change  2013 v 2012
Freight revenues	$	22,560	$	20,684	$	19,686		9%		5%
Other revenues		1,428		1,279		1,240		12%		3%
Total	$	23,988	$	21,963	$	20,926		9%		5%

We generate freight revenues 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 reductions to freight revenues based on the actual or projected future shipments. We recognize freight revenues as shipments move 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 from all six commodity groups increased during 2014 compared to 2013 driven by 7% volume growth and core pricing gains of 2.5%. Volume growth from grain, frac sand, rock, and intermodal (domestic and international) shipments offset declines in crude oil.

Freight revenues from five of our six commodity groups increased during 2013 compared to 2012. Revenue from Agricultural Products was down slightly compared to 2012. ARC increased 5%, driven by core pricing gains, shifts in business mix and an automotive logistics management arrangement. Volume essentially was flat year over year as growth in automotive, frac sand, crude oil and domestic intermodal offset declines in coal, international intermodal and grain shipments.

Our fuel surcharge programs generated freight revenues of $2.8 billion, $2.6 billion, and $2.6 billion in 2014, 2013, and 2012, respectively. Fuel surcharge in 2014 increased 6% driven by our 7% carloadings increase. Fuel surcharge in 2013 essentially was flat versus 2012 as lower fuel price offset improved fuel recovery provisions and the lag effect of our programs (surcharges trail fluctuations in fuel price by approximately two months).

In 2014, other revenue increased from 2013 due to higher revenues at our subsidiaries, primarily those that broker intermodal and automotive services, accessorial revenue driven by increased volume and per diem revenue for container usage (previously included in automotive freight revenue).

In 2013, other revenue increased from 2012 due primarily to miscellaneous contract revenue and higher revenues at our subsidiaries that broker intermodal and automotive services.

Agricultural Products – Higher volume and pricing gains drove the increase in freight revenue from agricultural shipments in 2014 versus 2013. Grain shipments increased 27%, reflecting the strong overall harvest in 2013 and 2014. The 2012 drought negatively impacted the first three quarters of 2013, which created favorable comparisons for the first three quarters of 2014. Lower export wheat shipments due to a larger world crop partially offset gains in grain. In 2013, lower volume offset price improvements as freight revenue declined slightly versus 2012. In the fourth quarter, grain shipments increased 41% due to a robust fall harvest. Despite the fourth quarter growth, grain shipments still

2014 Agricultural Products Carloads

decreased 4% for the full year when compared to 2012, reflecting the impact of the severe drought in 2012 that affected territory served by us during the first three quarters of 2013. Export wheat shipped to the Gulf and Pacific Northwest increased in the second half of 2013, partially offsetting the declines in grain.

Automotive – Freight revenue from automotive shipments increased compared to 2013. Growth in automotive parts and finished vehicle shipments and core price improvements drove the higher revenue. The increase in automotive parts volume was driven by continued strength in production and market penetration. Finished vehicles shipments increased the last three quarters of 2014 with improved sales and production, which offset declines in the first quarter due to winter weather. Shifts in business mix and a change in how we are compensated for container usage, which is now included as a per diem charge in other revenue, negatively impacted ARC compared to 2013. 2014 Automotive Carloads  

Higher ARC due to price increases and the logistics management arrangement that covers fees and container costs, coupled with increased shipments of automotive parts and finished vehicles, improved automotive revenue in 2013 compared to 2012. Higher production and sales levels during 2013 drove the volume growth.

Chemicals – Core price improvements, higher volumes and ARC driven by positive business mix increased freight revenue from chemicals compared to 2013. Shipments of industrial chemicals grew as a result of continued strong demand in the drilling market. Fertilizer shipments increased due to strong exports of potash. Reduced shipments of crude oil from the Bakken and Permian shale formations to the Gulf area partially offset these gains as market factors, primarily regional pricing differences for various types of crude oil, displaced some of the former Gulf Coast shipments to the East and West Coasts. 2014 Chemicals Carloads  

Volume gains and price improvement increased freight revenue from chemicals in 2013 versus 2012. Shipments of crude oil from the Bakken, Permian, Niobrara and Eagle Ford shale formations primarily to the Gulf area drove the growth in shipments of

27

chemicals. In addition, shipments of industrial chemicals increased as manufacturing, housing and automotive markets improved.

Coal – Freight revenue from coal shipments increased in 2014 compared to 2013, driven by higher volumes. Shifts in business mix negatively impacted ARC compared to 2013. Southern Powder River Basin (SPRB) shipments increased 3% from 2013. Strong demand continued throughout the year due to inventory replenishment but network performance and contract losses limited year-over-year volume growth. Shipments from Colorado and Utah mines increased 6% compared to 2013, driven by higher natural gas prices for most of the year and strong exports through the West Coast. However, in the fourth quarter volumes from Colorado and Utah mines declined as exports to the Gulf Coast decreased. 2014 Coal Carloads  

ARC gains driven by price increases and positive business mix, partially offset by volume declines, increased freight revenue from coal shipments in 2013 versus 2012. SPRB shipments declined 10% from 2012 due to the loss of a customer contract at the beginning of the year, relatively mild summer weather, and tighter coal inventory management by utilities. Shipments from Colorado and Utah mines decreased 13% compared to 2012, driven by soft domestic demand and mine production issues, partially offset by second half growth in international shipments. Severe flooding and washouts in Colorado also reduced volumes from certain producers in the third quarter.

Industrial Products – Volume growth, core pricing gains and positive business mix increased freight revenue from industrial products versus 2013. Shipments of non-metallic minerals (primarily frac sand, up 31%) grew as a result of drilling activity for energy products, as well as evolving drilling practices, which can increase the amount of frac sand used at certain wells. Additionally, rock and lumber shipments increased from 2013, driven by new housing and commercial construction. Freight revenue from industrial products increased in 2013 versus 2012 driven by volume growth and higher ARC due to pricing gains and favorable business mix. Shipments of non-metallic minerals (primarily frac sand) grew as a result of drilling activity for energy products. Additionally, growth in new housing construction and home improvements drove an

2014 Industrial Products Carloads

increase in lumber shipments. Declines in ferrous scrap and government shipments partially offset these higher volumes.

28

Intermodal – Freight revenue from intermodal shipments increased in 2014 compared to 2013 driven by volume growth, core pricing improvements and positive business mix. Domestic traffic increased 11% due to continued conversions from truck transportation to rail and new premium services. International traffic grew 5% versus 2013, driven primarily by new business and improving economic conditions. International gains in the last three quarters of the year offset the declines in the first quarter due to severe weather that negatively impacted consumer demand.   Pricing improvements and slight volume growth drove increased freight revenue from intermodal shipments in 2013 2014 Intermodal Carloads  

compared to 2012. Domestic traffic increased 3% due to overall economic growth along with conversions from truck transportation to rail. International traffic declined 2% versus 2012, reflecting market share shifts within the ocean carrier industry and an increase in transloading in the second half of the year. Transloading involves the transfer of goods from international to domestic containers at distribution centers near West coast ports, which reduces demand for rail transportation from these centers in international containers.

Mexico Business – Each of our commodity groups includes revenue from shipments to and from Mexico. Revenue from Mexico business increased 8% to $2.3 billion in 2014 versus 2013. Volume levels increased 8% from 2013, as increases in Agricultural Products, Chemicals, Intermodal, Automotive and Industrial Products offset lower export Coal shipments.

Revenue from Mexico business increased 9% to $2.1 billion in 2013 versus 2012. Shipments were up 3% versus 2012; all commodity groups grew with the exception of Agricultural Products. The largest growth came from Automotive and Industrial Products shipments.

Operating expenses increased $718 million in 2014 versus 2013. Volume-related expenses, incremental costs associated with operating a slower network, depreciation, wage and benefit inflation, and locomotive and freight car materials contributed to the higher costs. Lower fuel price partially offset these increases. In addition, there were approximately $35 million of weather related costs in the first quarter of 2014.   Operating expenses increased $336 million in 2013 versus 2012. Wage and benefit inflation, new logistics management fees and container costs for our automotive business, locomotive overhauls, property taxes and repairs on jointly owned property contributed to higher expenses during the year. Lower fuel prices partially offset the cost increases. 2014 Operating Expenses  

Compensation and Benefits – Compensation and benefits include wages, payroll taxes, health and welfare costs, pension costs, other postretirement benefits, and incentive costs. Volume-related expenses, including training, and a slower network increased our train and engine work force, which, along with general wage and benefit inflation, drove increased wages. Weather-related costs in the first quarter of 2014 also increased costs.

General wages and benefits inflation, including increased pension and other postretirement benefits, and higher work force levels drove the increases in 2013 versus 2012. The impact of ongoing productivity initiatives partially offset these increases.

Fuel – Fuel includes locomotive fuel and gasoline for highway and non-highway vehicles and heavy equipment. Volume growth of 7%, as measured by gross ton-miles, drove the increase in fuel expense. This was essentially offset by lower locomotive diesel fuel prices, which averaged $2.97 per gallon (including taxes and transportation costs) in 2014, compared to $3.15 in 2013, along with a slight improvement in fuel consumption rate, computed as gallons of fuel consumed divided by gross ton-miles.

Lower locomotive diesel fuel prices, which averaged $3.15 per gallon (including taxes and transportation costs) in 2013, compared to $3.22 in 2012, decreased expenses by $75 million. Volume, as measured by gross ton-miles, decreased 1% while the fuel consumption rate, computed as gallons of fuel consumed divided by gross ton-miles, increased 2% compared to 2012. Declines in heavier, more fuel-efficient coal shipments drove the variances in gross-ton-miles and the fuel consumption rate.

Purchased Services and Materials – Expense for purchased services and materials includes the costs of services purchased from outside contractors and other service providers (including equipment maintenance and contract expenses incurred by our subsidiaries for external transportation services); 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. Expenses for purchased services increased 8% compared to 2013 primarily due to volume-

30

related expenses incurred by our logistics subsidiaries for external transportation and increased crew transportation and lodging due to volumes and a slower network. In addition, higher consulting fees and higher contract expenses (including equipment maintenance) increased costs compared to 2013. Locomotive and freight car material expenses increased in 2014 compared to 2013 due to additional volumes, including the impact of activating stored equipment to address operational issues caused by demand and a slower network.

Expenses for purchased services increased 10% in 2013 compared to 2012 due to logistics management fees, an increase in locomotive overhauls and repairs on jointly owned property.

Depreciation – The majority of depreciation relates to road property, including rail, ties, ballast, and other track material. Depreciation was up 7% compared to 2013. A higher depreciable asset base, reflecting higher ongoing capital spending drove the increase.

Depreciation was up 1% in 2013 compared to 2012. Recent depreciation studies allowed us to use longer estimated service lives for certain equipment, which partially offset the impact of a higher depreciable asset base resulting from larger capital spending in recent years.

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; and office and other rent expenses. Higher intermodal volumes and longer cycle times increased short-term freight car rental expense in 2014 compared to 2013. Lower equipment leases essentially offset the higher freight car rental expense, as we exercised purchase options on some of our leased equipment.

Additional container costs resulting from the logistics management arrangement, and increased automotive shipments, partially offset by lower cycle times drove a $51 million increase in our short-term freight car rental expense in 2013 versus 2012. Conversely, lower locomotive and freight car lease expenses partially offset the higher freight car rental expense.

Other – Other expenses include state and local taxes, freight, equipment and property damage, utilities, insurance, personal injury, environmental, employee travel, telephone and cellular, computer software, bad debt, and other general expenses. Higher property taxes, personal injury expense and utilities costs partially offset by lower environmental expense and costs associated with damaged freight drove the increase in other costs in 2014 compared to 2013.

Higher property taxes and costs associated with damaged freight and property increased other costs in 2013 compared to 2012. Continued improvement in our safety performance and lower estimated liability for personal injury, which reduced our personal injury expense year-over-year, partially offset increases in other costs.

Non-Operating Items

Millions	2014		2013		2012		% Change  2014 v 2013		% Change  2013 v 2012
Other income	$	151	$	128	$	108		18%		19%

Income taxes		(3,163)		(2,660)		(2,375)		19%		12%

Other Income – Other income increased in 2014 versus 2013 due to higher gains from real estate sales and a sale of a permanent easement. These gains were partially offset by higher environmental costs on non-operating property in 2014 and lower lease income due to the $17 million settlement of a land lease contract in 2013.

Other income increased in 2013 versus 2012 due to higher gains from real estate sales and increased lease income, including the favorable impact from the $17 million settlement of a land lease contract. These increases were partially offset by interest received from a tax refund in 2012.

31

Interest Expense – Interest expense increased in 2014 versus 2013 due to an increased weighted-average debt level of $10.8 billion in 2014 from $9.6 billion in 2013, which more than offset the impact of the lower effective interest rate of 5.3% in 2014 versus 5.7% in 2013.

Interest expense decreased in 2013 versus 2012 due to a lower effective interest rate of 5.7% in 2013 versus 6.0% in 2012. The increase in the weighted-average debt level to $9.6 billion in 2013 from $9.1 billion in 2012 partially offset the impact of the lower effective interest rate.

Income Taxes – Higher pre-tax income increased income taxes in 2014 compared to 2013. Our effective tax rate for 2014 was 37.9% compared to 37.7% in 2013.

Higher pre-tax income increased income taxes in 2013 compared to 2012. Our effective tax rate for 2013 was 37.7% compared to 37.6% in 2012.

OTHER OPERATING/PERFORMANCE AND FINANCIAL STATISTICS

We report a number of key performance measures weekly to the Association of American Railroads (AAR). We provide this data on our website at www.up.com/investor/aar-stb_reports/index.htm.

Operating/Performance Statistics

Railroad performance measures are included in the table below:

	2014		2013		2012		% Change  2014 v 2013		% Change  2013 v 2012
Average train speed (miles per hour)		24.0		26.0		26.5		(8)%		(2)%
Average terminal dwell time (hours)		30.3		27.1		26.2		12 %		3 %
Gross ton-miles (billions)		1,014.9		949.1		959.3		7 %		(1)%
Revenue ton-miles (billions)		549.6		514.3		521.1		7 %		(1)%
Operating ratio		63.5		66.1		67.8		(2.6)pts		(1.7)pts
Employees (average)		47,201		46,445		45,928		2 %		1 %

Average Train Speed – Average train speed is calculated by dividing train miles by hours operated on our main lines between terminals. Average train speed, as reported to the Association of American Railroads, decreased 8% in 2014 versus 2013. The decline was driven by a 7% volume increase, a major infrastructure project in Fort Worth, Texas and inclement weather, including flooding in the Midwest in the second quarter and severe weather conditions in the first quarter that impacted all major U.S. and Canadian railroads.

Average train speed decreased 2% in 2013 versus 2012. The decline was driven by severe weather conditions and shifts of traffic to sections of our network with higher utilization.

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 increased 12% in 2014 compared to 2013, caused by higher volumes and inclement weather.

Average terminal dwell time increased 3% in 2013 compared to 2012, primarily due to growth of manifest traffic which requires more time in terminals for switching cars and building trains.

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 ton-miles, revenue ton-miles and carloadings all increased 7% in 2014 compared to 2013.

Gross ton-miles and revenue ton-miles declined 1% in 2013 compared to 2012 and carloads remained relatively flat driven by declines in coal and agricultural products offset by growth in chemical, autos and industrial products. Changes in commodity mix drove the year-over-year variances between gross ton-miles, revenue ton-miles and carloads.

32

Operating Ratio – Operating ratio is our operating expenses reflected as a percentage of operating revenue. Our operating ratio improved 2.6 points to a new record low of 63.5% in 2014 versus 2013. Core pricing, business demand and productivity more than offset the incremental operating costs associated with volume, a slower network, weather and inflation.

Our operating ratio improved 1.7 points to a then record low of 66.1% in 2013 versus 2012. Core pricing and productivity gains more than offset the impact of inflation.

Employees – Employee levels increased 2% in 2014 versus 2013. A decrease in our capital workforce due to improved productivity and project mix partially offset the larger train and engine workforce required for higher volume levels and a slower network. We successfully managed the growth of our full-time equivalent train and engine force levels at a rate less than our volume growth in 2014 compared to 2013.

Employee levels increased 1% in 2013 versus 2012. Shifts in our traffic mix, which required more resources, largely concentrated in the Southern region, work related to higher capital investment in positive train control and more individuals in the training pipeline contributed to the higher employee levels.

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 our long-term capital investments. In addition, 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 reconciliations from return on average common shareholders’ equity to ROIC. Our 2014 ROIC improved 1.5 points compared to 2013, primarily as a result of higher earnings.

Adjusted capital (b)	$	36,094	$	34,029
Adjusted debt to capital (a/b)		41.3%		37.6%

Adjusted debt to capital is a non-GAAP financial measure under 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 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 5.3% and 5.7% at December 31, 2014 and 2013, respectively. The discount rate reflects our effective interest rate. 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 our 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 reconciliations from debt to capital to adjusted debt to capital. Our December 31, 2014 debt to capital ratios increased as a result of a $1.9 billion increase in debt from December 31, 2013.

LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 2014, our principal sources of liquidity included cash, cash equivalents, our receivables securitization facility, and our revolving credit facility, as well as the availability of commercial paper and other sources of financing through the capital markets. We had $1.7 billion of committed credit available under our credit facility, with no borrowings outstanding as of December 31, 2014. We did not make any borrowings under this facility during 2014. The value of the outstanding undivided interest held by investors under the $650 million capacity receivables securitization facility was $400 million as of December 31, 2014, and is included in our Consolidated Statements of Financial Position as debt due after one year. Our access to this receivables securitization facility may be reduced or restricted if our bond ratings fall to certain levels below investment grade. 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 access capital markets 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 have access to liquidity through any or all of the following sources or activities: (i) increasing the size or utilization of our receivables securitization, (ii) issuing commercial paper, (iii) entering into bank loans, outside of our revolving credit facility, or (iv) issuing bonds or other debt securities to public or private investors based on our assessment of the current condition of the credit markets. The Company’s $1.7 billion revolving credit facility is intended to support the issuance of commercial paper by UPC and also serves as an emergency source of liquidity. The Company currently does not intend to make any borrowings under this facility.

At December 31, 2014 and 2013, we had a modest working capital surplus. This reflects a strong cash position that provides enhanced liquidity in an uncertain economic environment. In addition, we believe

34

we have adequate access to capital markets to meet any foreseeable cash requirements, and we have sufficient financial capacity to satisfy our current liabilities.

Cash Flows Millions	2014		2013		2012
Cash provided by operating activities	$	7,385	$	6,823	$	6,161
Cash used in investing activities		(4,249)		(3,405)		(3,633)
Cash used in financing activities		(2,982)		(3,049)		(2,682)

Operating Activities

Higher net income in 2014 increased cash provided by operating activities compared to 2013, despite higher income tax payments. 2014 income tax payments were higher than 2013 primarily due to higher income, but also because we paid taxes previously deferred by bonus depreciation (discussed below).

Higher net income in 2013 increased cash provided by operating activities compared to 2012. In addition, we made payments in 2012 for past wages as a result of national labor negotiations, which reduced cash provided by operating activities in 2012. Lower tax benefits from bonus depreciation (as discussed below) partially offset the increases.

Federal tax law provided for 100% bonus depreciation for qualified investments made during 2011 and 50% bonus depreciation for qualified investments made during 2012-2013. As a result, the Company deferred a substantial portion of its 2011-2013 income tax expense, contributing to the positive operating cash flow in those years. Congress extended 50% bonus depreciation for 2014, but this extension occurred in December and did not have a significant benefit on our income tax payments during 2014.

Investing Activities

Higher capital investments, including the early buyout of the long-term operating lease of our headquarters building for approximately $261 million, drove the increase in cash used in investing activities compared to 2013. Significant investments also were made for new locomotives, freight cars and containers, and capacity and commercial facility projects. Capital investments in 2014 also included $99 million for the early buyout of locomotives and freight cars under long-term operating leases, which we exercised due to favorable economic terms and market conditions.

Lower capital investments in locomotives and freight cars in 2013 drove the decrease in cash used in investing activities compared to 2012. Included in capital investments in 2012 was $75 million for the early buyout of 165 locomotives under long-term operating and capital leases during the first quarter of 2012, which we exercised due to favorable economic terms and market conditions.

Capital Plan – In 2015, we expect our capital plan to be approximately $4.3 billion, which may be revised if business conditions or the regulatory environment affect our ability to generate sufficient returns on these investments. While asset replacements will fluctuate as part of our renewal strategy, we expect to use 55% to 60% of our capital investments to renew and improve existing capital assets. Our major investment categories include renewing track infrastructure and upgrading our fleet of locomotives, freight cars, and domestic intermodal containers. In 2015, we plan to acquire 218 locomotives and increase freight car and container acquisitions. Additionally, we will continue increasing our network and terminal capacity, especially in the Southern region, while balancing terminal capacity with mainline capacity. In 2015, we also plan to begin constructing a major classification yard at Hearne, Texas, and continue developing several intermodal, automotive and chemicals facilities. Significant investments in technology improvements are planned, including approximately $450 million for PTC.

We expect to fund our 2015 cash capital plan by using some or all of the following: cash generated from operations, proceeds from the sale or lease of various operating and non-operating properties, proceeds from the issuance of long-term debt, and cash on hand. Our annual capital plan is a critical component of our long-term strategic plan. We expect our plan will enhance the long-term value of the Company 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 remained flat in 2014 versus 2013. Increases for the repurchase of shares under our common stock repurchase program and higher dividend payments in 2014 of $1.6 billion compared to $1.3 billion in 2013 were offset by higher debt issuances in 2014.

Cash used in financing activities increased in 2013 versus 2012, driven by a $744 million increase for the repurchase of shares under our common stock repurchase program and higher dividend payments in 2013 of $1.3 billion compared to $1.1 billion in 2012. We increased our debt levels in 2013, which partially offset the increase in cash used in financing activities.

36

Dividends – On February 5, 2015, we increased the quarterly dividend to $0.55 per share, payable on March 30, 2015, to shareholders of record on February 27, 2015, We expect to fund the increase in the quarterly dividend through cash generated from operations and cash on hand at December 31, 2014.

Credit Facilities – During the second quarter of 2014, we replaced our $1.8 billion revolving credit facility, which was scheduled to expire in May 2015, with a new $1.7 billion facility that expires in May 2019 (the facility). The facility is based on substantially similar terms as those in the previous credit facility. On December 31, 2014, we had $1.7 billion of credit available under the facility, which is designated for general corporate purposes and supports the issuance of commercial paper. We did not draw on either facility at any time during 2014. 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 credit ratings for our senior unsecured debt.

The facility requires that the Corporation maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing. At December 31, 2014, and December 31, 2013 (and at all times during the year), 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, 2014, the debt-to-net-worth coverage ratio allowed us to carry up to $42.4 billion of debt (as defined in the facility), and we had $11.6 billion of debt (as defined in the facility) outstanding at that date. Under our current capital plans, we expect to continue to satisfy the debt-to-net-worth coverage ratio; however, many factors beyond our reasonable control could affect our ability to comply with this provision in the future. The facility does not include any other financial restrictions, credit rating triggers (other than rating-dependent pricing), or any other provision that could require us to post collateral. The facility also includes a $125 million cross-default provision and a change-of-control provision.

During 2014, we did not issue or repay any commercial paper, and at December 31, 2014, and 2013, we had no commercial paper outstanding. Our revolving credit facility supports our outstanding commercial paper balances, and, unless we change the terms of our commercial paper program, our aggregate issuance of commercial paper will not exceed the amount of borrowings available under the facility.

(See further discussion in this Item 7 under Receivables Securitization Facility for information regarding the Company’s receivables securitization facility.)

Ratio of Earnings to Fixed Charges

For each of the years ended December 31, 2014, 2013, and 2012, our ratio of earnings to fixed charges was 13.5, 11.8, and 10.4, 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.)

Common Shareholders’ Equity

Dividend Restrictions – Our revolving credit facility includes a debt-to-net worth covenant (discussed in the Credit Facilities section above) that, under certain circumstances, restricts the payment of cash dividends to our shareholders. The amount of retained earnings available for dividends was $15.4 billion and $16.3 billion at December 31, 2014, and 2013, respectively.

37

Share Repurchase Program

Effective January 1, 2014, our Board of Directors authorized the repurchase of up to 120 million shares of our common stock by December 31, 2017, replacing our previous repurchase program. As of December 31, 2014, we repurchased a total of $12.6 billion of our common stock since the commencement of our repurchase programs in 2007. The table below represents shares repurchased in 2013 under our previous repurchase program, and shares repurchased in 2014 under the new program.

	Number of Shares Purchased				Average Price Paid

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

From January 1, 2015, through February 6, 2015, we repurchased 2.8 million shares at an aggregate cost of approximately $327 million.

Shelf Registration Statement and Significant New Borrowings – Under our current shelf registration, we may issue, from time to time, any combination of debt securities, preferred stock, common stock, or warrants for debt securities or preferred stock in one or more offerings. We have no immediate plans to issue equity securities; however, we will continue to explore opportunities to replace existing debt or access capital through issuances of debt securities under our shelf registration, and, therefore, we may issue additional debt securities at any time.

During 2014, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
January 10, 2014	$300 million of 2.25% Notes due February 15, 2019
	$400 million of 3.75% Notes due March 15, 2024
	$300 million of 4.85% Notes due June 15, 2044
August 12, 2014	$350 million of 3.25% Notes due January 15, 2025
	$350 million of 4.15% Notes due January 15, 2045

We used the net proceeds from the offerings for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities include change-of-control provisions. At December 31, 2014, we had remaining authority to issue up to $1.15 billion of debt securities under our shelf registration.

Subsequent Event – In 2015, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
January 29, 2015	$250 million of 1.80% Notes due February 1, 2020
	$450 million of 3.375% Notes due February 1, 2035
	$450 million of 3.875% Notes due February 1, 2055

38

Proceeds from this offering are for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities include change-of-control provisions. This offering exhausted our current authority to issue debt securities under our existing shelf registration.

On February 5, 2015, the Board of Directors approved proceeding with a new shelf registration statement and authorized the issuance of up to $4.0 billion of debt securities.

Equipment Trust – On May 20, 2014, UPRR consummated a pass-through (P/T) financing, whereby a P/T trust was created, which issued $500 million of P/T trust certificates with a stated interest rate of 3.227%. The P/T trust certificates will mature on May 14, 2026. The proceeds from the issuance of the P/T trust certificates (net of $3 million in transaction fees) were used to purchase equipment trust certificates to be issued by UPRR to finance the acquisition of 245 locomotives. The equipment trust certificates are secured by a lien on the locomotives.

Debt Exchange – On August 21, 2013, we exchanged $1,170 million of various outstanding notes and debentures due between 2016 and 2040 (the Existing Notes) for $439 million of 3.646% notes (the New 2024 Notes) due February 15, 2024 and $700 million of 4.821% notes (the New 2044 Notes) due February 1, 2044, plus cash consideration of approximately $280 million in addition to $8 million for accrued and unpaid interest on the Existing Notes. In accordance with ASC 470-50-40, Debt-Modifications and Extinguishments-Derecognition, this transaction was accounted for as a debt exchange, as the exchanged debt instruments are not considered to be substantially different. The cash consideration was recorded as an adjustment to the carrying value of debt, and the balance of the unamortized discount and issue costs from the Existing Notes is being amortized as an adjustment of interest expense over the terms of the New 2024 Notes and the New 2044 Notes. No gain or loss was recognized as a result of the exchange. Costs related to the debt exchange that were payable to parties other than the debt holders totaled approximately $9 million and were included in interest expense during the three months ended September 30, 2013.

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

5.780% Notes due 2040		286
Total	$	1,170

Debt Redemption – On May 14, 2013, we redeemed all $40 million of our outstanding 5.65% Port of Corpus Christi Authority Revenue Refunding Bonds due December 1, 2022. The redemption resulted in an early extinguishment charge of $1 million in the second quarter of 2013.

Receivables Securitization Facility – On July 29, 2014, we completed the renewal of our receivables securitization facility. The new $650 million, 3-year facility replaces the prior $600 million, 364-day facility. Under the facility, the Railroad sells most of its eligible third-party receivables to Union Pacific Receivables, Inc. (UPRI), a wholly-owned, bankruptcy-remote subsidiary that may subsequently transfer, without recourse, an undivided interest in accounts receivable to investors. The investors have no

39

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.

The amount outstanding under the facility was $400 million and $0 at December 31, 2014, and December 31, 2013, respectively. The facility was supported by $1.2 billion and $1.1 billion of accounts receivable as collateral at December 31, 2014, and December 31, 2013, respectively, which, as a retained interest, is included in accounts receivable, net in our Consolidated Statements of Financial Position.

The outstanding amount the Railroad is allowed to maintain under the facility, with a maximum of $650 million, may fluctuate based on the availability of eligible receivables and is directly affected by business volumes and credit risks, including receivables payment quality measures such as default and dilution ratios. If default or dilution ratios increase one percent, the allowable outstanding amount under the facility would not materially change.

The costs of the receivables securitization facility include interest, which will vary based on prevailing benchmark and commercial paper rates, program fees paid to participating banks, commercial paper issuing costs, and fees of participating banks for unused commitment availability. The costs of the receivables securitization facility are included in interest expense and were $4 million, $5 million and $3 million for 2014, 2013, and 2012, respectively.

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, 2014:

			Payments Due by December 31,

[d] None of the letters of credit were drawn upon as of December 31, 2014.

Off-Balance Sheet Arrangements

Guarantees – At December 31, 2014, and 2013, we were contingently liable for $82 million and $299 million in guarantees. We have recorded liabilities of $0.3 million and $1 million for the fair value of these obligations as of December 31, 2014, and 2013, respectively. We entered into these contingent guarantees in the normal course of business, and they include guaranteed obligations related to our 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

Labor Agreements – Approximately 85% of our 47,201 full-time-equivalent employees are represented by 14 major rail unions. On January 1, 2015, current labor agreements became subject to modification and we began the current round of negotiations with the unions. Existing agreements remain in effect until new agreements are reached or the Railway Labor Act’s procedures (which include mediation, cooling-off periods, and the possibility of Presidential Emergency Boards and Congressional intervention) are exhausted. Contract negotiations historically continue for an extended period of time and we rarely experience work stoppages while negotiations are pending.

Inflation – Long periods of inflation significantly increase 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, 2014 and 2013, we were not required to provide collateral, nor had we received collateral, relating to our hedging activities.

41

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.

At December 31, 2014, we had variable-rate debt representing approximately 5.3% of our total debt. If variable interest rates average one percentage point higher in 2015 than our December 31, 2014 variable rate, which was approximately 0.9%, 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, 2014.

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, 2014, and amounts to an increase of approximately $1.3 billion to the fair value of our debt at December 31, 2014. 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) ASC 815; therefore, we do not record any ineffectiveness within our Consolidated Financial Statements. As of December 31, 2014 and 2013, we had no interest rate fair value hedges outstanding.

Interest Rate Cash Flow Hedges – We report changes in the fair value of cash flow hedges in accumulated other comprehensive loss until the hedged item affects earnings. At December 31, 2014, and 2013, we had reductions of $0 and $1 million, respectively, recorded as an accumulated other comprehensive loss. As of December 31, 2014, and 2013, we had no interest rate cash flow hedges outstanding.

Accounting Pronouncements – In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the revenue recognition guidance in Topic 605, Revenue Recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in the exchange for those goods or services. This standard is effective for annual reporting periods beginning after December 15, 2016. ASU 2014-09 is not expected to 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

42

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.

Personal Injury – The cost of personal injuries to employees and others related to our activities is charged to expense based on estimates of the ultimate cost and number of incidents each year. We use an actuarial analysis to measure the expense and liability, including unasserted claims. The Federal Employers’ Liability Act (FELA) governs compensation for work-related accidents. Under FELA, damages are assessed based on a finding of fault through litigation or out-of-court settlements. We offer a comprehensive variety of services and rehabilitation programs for employees who are injured at work.

Our personal injury liability is not discounted to present value due to the uncertainty surrounding the timing of future payments. Approximately 93% of the recorded liability is related to asserted claims and approximately 7% is related to unasserted claims at December 31, 2014. 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 $335 million to $368 million. We record an accrual at the low end of the range as no amount of loss within the range is more probable than any other. Estimates can vary over time due to evolving trends in litigation.

Our personal injury liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	294	$	334	$	368
Current year accruals		96		87		121
Changes in estimates for prior years		9		(38)		(58)
Payments		(64)		(89)		(97)
Ending balance at December 31	$	335	$	294	$	334
Current portion, ending balance at December 31	$	111	$	82	$	95

43

Our personal injury claims activity was as follows:

	2014		2013		2012
Open claims, beginning balance		2,605		2,792		2,869
New claims		2,773		2,705		2,719
Settled or dismissed claims		(2,760)		(2,892)		(2,796)
Open claims, ending balance at December 31		2,618		2,605		2,792

In conjunction with the liability update performed in 2014, we also reassessed our estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2014, and 2013.

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

• The ratio of future claims by alleged disease would be consistent with historical averages adjusted for inflation.

• 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, 2014. 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 $126 million to $135 million. We record an accrual at the low end of the range as no amount of loss within the range is more probable than any other.

Our asbestos-related liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	131	$	139	$	147
Accruals/(Credits)		1		2		(2)
Payments		(6)		(10)		(6)
Ending balance at December 31	$	126	$	131	$	139
Current portion, ending balance at December 31	$	8	$	9	$	8
Our asbestos-related claims activity was as follows:
	2014		2013		2012
Open claims, beginning balance		1,140		1,258		1,291
New claims		183		192		233
Settled or dismissed claims		(258)		(310)		(266)
Open claims, ending balance at December 31		1,065		1,140		1,258

In conjunction with the liability update performed in 2014, we also reassessed our estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2014, and 2013. The amounts recorded for asbestos-related liabilities and related insurance recoveries were based on currently known facts. However, future events, such as the number of new claims filed each year, average settlement costs, and insurance coverage issues, could cause the actual costs and insurance recoveries to be higher or lower than the projected amounts. Estimates also may vary in the future if

44

strategies, activities, and outcomes of asbestos litigation materially change; federal and state laws governing asbestos litigation increase or decrease the probability or amount of compensation of claimants; and there are material changes with respect to payments made to claimants by other defendants.

Environmental Costs – We are subject to federal, state, and local environmental laws and regulations. We have identified 270 sites at which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 29 sites that are the subject of actions taken by the U.S. government, 16 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 perform, with assistance of our consultants, environmental assessments on the property. We expense the cost of the assessments as incurred. We accrue the cost of remediation where our obligation is probable and such costs can be reasonably estimated. Our environmental liability is not discounted to present value due to the uncertainty surrounding the timing of future payments.

Our environmental liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	171	$	170	$	172
Accruals		56		58		48
Payments		(45)		(57)		(50)
Ending balance at December 31	$	182	$	171	$	170
Current portion, ending balance at December 31	$	60	$	53	$	50

Our environmental site activity was as follows:

	2014		2013		2012
Open sites, beginning balance		268		284		285
New sites		55		41		56
Closed sites		(53)		(57)		(57)
Open sites, ending balance at December 31		270		268		284

The environmental liability includes future costs for remediation and restoration of sites, as well as ongoing monitoring costs, but excludes any anticipated recoveries from third parties. Cost estimates are based on information available for each site, financial viability of other potentially responsible parties, and existing technology, laws, and regulations. The ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties, site-specific cost sharing arrangements with other potentially responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs. Estimates of liability may vary over time due to changes in federal, state, and local laws governing environmental remediation. Current obligations are not expected to have a material adverse effect on our consolidated results of operations, financial condition, or liquidity.

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) for which lives 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 lives are grouped together in asset classes,

45

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 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 2014, the estimated service lives of the majority of this rail ranged from approximately 18 years to approximately 35 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 $63 million. If the estimated useful lives of all depreciable assets were decreased by one year, annual depreciation expense would increase by approximately $68 million. Our recent depreciation studies have resulted in lower depreciation rates for some asset classes. The lower rates combined with a projected higher depreciable asset base will increase total depreciation expense by approximately 4% to 6% in 2015 versus 2014.

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 lives 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. In addition, we determine if the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by our depreciation studies. Any deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the applicable classes of assets.

46

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) it is unusual, (ii) it is material in amount, and (iii) it 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 tax legislation are not anticipated. Future tax legislation, 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 $380 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 for purposes of estimating whether future taxable income will be sufficient to realize a deferred tax asset. In 2014 and 2013, there were no valuation allowances.

We recognize tax benefits 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 an actuarial analysis to measure the liabilities and expenses associated with providing pension and 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 health care 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.

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

The following tables present the key assumptions used to measure net periodic pension and OPEB cost/(benefit) for 2014 and the estimated impact on 2014 net periodic pension and OPEB cost/(benefit) relative to a change in those assumptions:

Assumptions	Pension		OPEB
Discount rate		4.72%		4.47%
Expected return on plan assets		7.50%		N/A
Compensation increase		4.00%		N/A
Health care cost trend rate:
Pre-65 current		N/A		6.49%
Pre-65 level in 2028		N/A		4.50%

Sensitivities	Increase in Expense
Millions	Pension		OPEB
0.25% decrease in discount rate	$	9	$	1
0.25% increase in compensation scale	$	6		N/A
0.25% decrease in expected return on plan assets	$	8		N/A
1% increase in health care cost trend rate		N/A	$	2

The following table presents the net periodic pension and OPEB cost for the years ended December 31:

Millions	Est.  2015		2014		2013		2012
Net periodic pension cost	$	105	$	69	$	110	$	89
Net periodic OPEB cost		18		15		14		13

Our net periodic pension cost is expected to increase to approximately $105 million in 2015 from $69 million in 2014. Our net periodic OPEB expense is expected to increase to approximately $18 million in 2015 from $15 million in 2014. The increases are driven by the implementation of new mortality tables issued by the Society of Actuaries in October 2014, along with a decrease in the pension discount rate to 3.94% and a decrease in the OPEB discount rate to 3.74%.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Union Pacific Corporation

Omaha, Nebraska

We have audited the accompanying consolidated statements of financial position of Union Pacific Corporation and Subsidiary Companies (the “Corporation”) as of December 31, 2014 and 2013, and the related consolidated statements of income, comprehensive income, changes in common shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2014. 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 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, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, 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.

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, 2014, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 6, 2015 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”, “Company”, “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 operating in the U.S. Our network includes 31,974 route miles, linking Pacific Coast and Gulf Coast ports with the Midwest and Eastern U.S. gateways and providing several corridors to key Mexican gateways. We own 26,012 miles and operate on the remainder pursuant to trackage rights or leases. 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 we provide and review 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. The following table provides freight revenue by commodity group:

Millions	2014		2013		2012
Agricultural Products	$	3,777	$	3,276	$	3,280
Automotive		2,103		2,077		1,807
Chemicals		3,664		3,501		3,238
Coal		4,127		3,978		3,912
Industrial Products		4,400		3,822		3,494
Intermodal		4,489		4,030		3,955
Total freight revenues	$	22,560	$	20,684	$	19,686
Other revenues		1,428		1,279		1,240
Total operating revenues	$	23,988	$	21,963	$	20,926

Although our revenues are principally derived from customers domiciled in the U.S., the ultimate points of origination or destination for some products transported by us are outside the U.S. Each of our commodity groups includes revenue from shipments to and from Mexico. Included in the above table are revenues from our Mexico business which amounted to $2.3 billion in 2014, $2.1 billion in 2013, and $1.9 billion in 2012.

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

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.

Accounts Receivable – Accounts receivable includes receivables reduced by an allowance for doubtful accounts. The allowance is based upon historical losses, credit worthiness of customers, and current economic conditions. Receivables not expected to be collected in one year and the associated allowances are classified as other assets in our Consolidated Statements of Financial Position.

56

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 – 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), for which lives 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 lives 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 determine the estimated service lives of depreciable railroad assets by means of depreciation studies. Under the group method of depreciation, no gain or loss is recognized when depreciable property is retired or replaced in the ordinary course of business.

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 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, which include revenues earned by our subsidiaries, revenues from our commuter rail operations, and accessorial revenue, 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.

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 and short- and long-term debt.

Stock-Based Compensation – We have several stock-based compensation plans under which employees and non-employee directors receive stock options, nonvested retention shares, and nonvested stock units. We refer to the nonvested shares and stock units collectively as “retention awards”. We have elected to issue treasury shares to cover option exercises and stock unit vestings, while new shares are issued when retention shares are granted.

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.

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.

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 tax legislation are not anticipated. Future tax legislation, 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 for purposes of estimating whether future taxable income will be sufficient to realize a deferred tax asset.

We recognize tax benefits 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, compensation increases, employee turnover rates, anticipated mortality rates, and expected future health care costs. The assumptions used by us are based on our historical experience as well as current facts and circumstances. We use an actuarial analysis to measure 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 an actuarial analysis to measure the expense and liability. Our personal injury liability is not discounted to present value. 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 a statistical analysis 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 perform, with the assistance of our consultants, 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.

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.

3. Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the revenue recognition guidance in Topic 605, Revenue Recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in the exchange for those goods or services. This

58

standard is effective for annual reporting periods beginning after December 15, 2016. ASU 2014-09 is not expected to have a material impact on our consolidated financial position, results of operations, or cash flows.

4. Stock Split

On June 6, 2014, 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 27, 2014, 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 retroactively adjusted to reflect the stock split for all periods presented.

5. Stock Options and Other Stock Plans

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 awards of restricted shares under this plan.

In April 2000, the shareholders approved the Union Pacific Corporation 2000 Directors Plan (Directors Plan) whereby 2,200,000 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 4,000 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 20,000 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. In September 2007, the Board of Directors eliminated the annual payment of options for 2008 and all future years. As of December 31, 2014, 36,000 restricted shares and 78,000 options were outstanding under the Directors Plan.

The Union Pacific Corporation 2004 Stock Incentive Plan (2004 Plan) was approved by shareholders in April 2004. The 2004 Plan reserved 84,000,000 shares of our common stock for issuance, plus any shares subject to awards made under previous plans 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, 2014, 4,338,691 options and 3,677,642 retention shares and stock units were outstanding under the 2004 Plan. We no longer grant any stock options or other stock or unit awards under this plan.

The Union Pacific Corporation 2013 Stock Incentive Plan (2013 Plan) was approved by shareholders in May 2013. The 2013 Plan reserved 78,000,000 shares of our common stock for issuance, plus any shares subject to awards made under previous plans as of February 28, 2013, that are subsequently cancelled, expired, forfeited or otherwise not issued under previous plans. Under the 2013 Plan, non-qualified options, incentive stock options, 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 2013 Plan. As of December 31, 2014, 969,822 options and 1,307,905 retention shares and stock units were outstanding under the 2013 Plan.

Pursuant to the above plans 77,786,772; 79,574,896; and 64,337,040 shares of our common stock were authorized and available for grant at December 31, 2014, 2013, and 2012, respectively.

Stock-Based Compensation – We have several stock-based compensation plans under which employees and non-employee directors receive stock options, nonvested retention shares, and nonvested stock units. We refer to the nonvested shares and stock units collectively as “retention awards”. We have elected to issue treasury shares to cover option exercises and stock unit vestings, while new shares are issued when retention shares are granted.

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

Millions	2014		2013		2012
Stock-based compensation, before tax:
Stock options	$	21	$	19	$	18
Retention awards		91		79		75
Total stock-based compensation, before tax	$	112	$	98	$	93
Excess tax benefits from equity compensation plans	$	118	$	76	$	100

Stock Options – We estimate the fair value of our stock option awards using the Black-Scholes option pricing model. The table below shows the annual weighted-average assumptions used for valuation purposes:

Weighted-Average Assumptions	2014		2013		2012
Risk-free interest rate		1.6%		0.8%		0.8%
Dividend yield		2.1%		2.1%		2.1%
Expected life (years)		5.2		5.0		5.3
Volatility		30.0%		36.2%		36.8%
Weighted-average grant-date fair value of options granted	$	20.18	$	17.49	$	15.65

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 2014 is presented below:

	Options  (thous.)		Weighted-  Average  Exercise Price		Weighted-Average  Remaining  Contractual Term		Aggregate  Intrinsic Value  (millions)
Outstanding at January 1, 2014		7,443	$	40.07		5.8 yrs.	$	327
Granted		989		87.56		N/A		N/A
Exercised		(2,961)		30.59		N/A		N/A
Forfeited or expired		(84)		68.48		N/A		N/A
Outstanding at December 31, 2014		5,387	$	53.56		5.8 yrs.	$	353
Vested or expected to vest at December 31, 2014		5,325	$	53.30		5.8 yrs.	$	351
Options exercisable at December 31, 2014		3,350	$	40.69		4.4 yrs.	$	263

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, 2014, are subject to performance or market-based vesting conditions.

At December 31, 2014, there was $15 million of unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted-average period of 1 year. Additional information regarding stock option exercises appears in the table below:

Millions	2014		2013		2012
Intrinsic value of stock options exercised	$	194	$	112	$	244
Cash received from option exercises		54		51		84
Treasury shares repurchased for employee payroll taxes		(24)		(21)		(30)
Tax benefit realized from option exercises		74		43		93
Aggregate grant-date fair value of stock options vested		17		16		16

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 2014 were as follows:

	Shares  (thous.)		Weighted-Average  Grant-Date Fair Value
Nonvested at January 1, 2014		3,712		$    49.02
Granted		871		88.14
Vested		(1,080)		31.33
Forfeited		(100)		57.82
Nonvested at December 31, 2014		3,403		$    64.39

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, 2014, there was $87 million of total unrecognized compensation expense related to nonvested retention awards, which is expected to be recognized over a weighted-average period of 1.6 years.

Performance Retention Awards – In February 2014, our Board of Directors approved performance stock unit grants. Other than different performance targets, the basic terms of these performance stock units are identical to those granted in February 2012 and February 2013, including using annual return on invested capital (ROIC) as the performance measure. We define ROIC as net operating profit adjusted for interest expense (including interest on the present value of operating leases) and taxes on interest divided by average invested capital adjusted for the present value of operating leases.

Stock units awarded to selected employees under these grants are subject to continued employment for 37 months and the attainment of certain levels of ROIC. We expense the fair value of the units that are probable of being earned based on our forecasted ROIC over the 3-year performance period. We measure the fair value of these performance stock units based upon the closing price of the underlying common stock as of the date of grant, reduced by the present value of estimated future dividends. Dividend equivalents are paid to participants only after the units are earned.

The assumptions used to calculate the present value of estimated future dividends related to the February 2014 grant were as follows:

	2014
Dividend per share per quarter	$	0.455
Risk-free interest rate at date of grant		0.7%

Changes in our performance retention awards during 2014 were as follows:

	Shares  (thous.)		Weighted-Average  Grant-Date Fair Value
Nonvested at January 1, 2014		1,888		$    53.70
Granted		456		83.06
Vested		(661)		44.94
Forfeited		(100)		61.36
Nonvested at December 31, 2014		1,583		$    65.33

At December 31, 2014, there was $36 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 year. 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 medical and life insurance benefits for eligible retirees. These benefits are funded as medical claims and life insurance premiums are paid.

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 projected benefit obligation (PBO) and the fair value of the plan assets. Our non-qualified (supplemental) pension plan is unfunded by design. The PBO of the pension plans is the present value of benefits earned to date by plan participants, including the effect of assumed future compensation 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 compensation 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 were as follows for the years ended December 31:

Funded Status	Pension				OPEB
Millions	2014		2013		2014		2013
Projected Benefit Obligation
Projected benefit obligation at beginning of year	$	3,372	$	3,591	$	330	$	372

Funded status at end of year	$	(488)	$	57	$	(354)	$	(330)

Amounts recognized in the statement of financial position as of December 31, 2014 and 2013 consist of:

	Pension				OPEB

Net amounts recognized at end of year	$	(488)	$	57	$	(354)	$	(330)

62

The change in the funded status and accumulated other comprehensive income/(loss) is primarily a result of implementing a new set of mortality tables issued by the Society of Actuaries in October 2014 and lower discount rates.

Pre-tax amounts recognized in accumulated other comprehensive income/(loss) as of December 31, 2014 and 2013 consist of:

	2014						2013
Millions	Pension		OPEB		Total		Pension		OPEB		Total
Prior service (cost)/credit	$	-	$	17	$	17	$	-	$	28	$	28

Total	$	(1,727)	$	(131)	$	(1,858)	$	(1,018)	$	(97)	$	(1,115)

Pre-tax changes recognized in other comprehensive income/(loss) during 2014, 2013 and 2012 were as follows:

	Pension						OPEB

Net actuarial loss		(103)		(13)		(116)
Total	$	(103)	$	(3)	$	(106)

Underfunded Accumulated Benefit Obligation – The accumulated benefit obligation (ABO) is the present value of benefits earned to date, assuming no future compensation growth. The underfunded accumulated benefit obligation represents the difference between the ABO and the fair value of plan assets. At December 31, 2014 and 2013, the non-qualified (supplemental) plan ABO was $379 million and $302 million, respectively. The following table discloses only the PBO, ABO, and fair value of plan assets for pension plans where the accumulated benefit obligation is in excess of the fair value of the plan assets as of December 31:

Underfunded Accumulated Benefit Obligation Millions	2014		2013
Projected benefit obligation	$	388	$	308
Accumulated benefit obligation	$	379	$	302
Fair value of plan assets		-		-
Underfunded accumulated benefit obligation	$	(379)	$	(302)

The ABO for all defined benefit pension plans was $3.9 billion and $3.2 billion at December 31, 2014 and 2013, respectively.

63

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

	Pension				OPEB
Percentages	2014		2013		2014		2013
Discount rate		3.94%		4.72%		3.74%		4.47%
Compensation increase		4.00%		4.00%		N/A		N/A
Health care cost trend rate (employees under 65)		N/A		N/A		6.34%		6.49%
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 in accumulated other comprehensive income and, if necessary, amortized as pension or OPEB expense.

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

	Pension						OPEB
Millions	2014		2013		2012		2014		2013		2012
Net Periodic Benefit Cost:
Service cost	$	70	$	72	$	54	$	2	$	3	$	3
Interest cost		158		134		141		14		12		15
Expected return on plan assets		(230)		(202)		(190)		-		-		-
Amortization of:
Prior service cost/(credit)		-		-		1		(11)		(16)		(18)
Actuarial loss		71		106		83		10		15		13
Net periodic benefit cost/(benefit)	$	69	$	110	$	89	$	15	$	14	$	13

Assumptions – The weighted-average actuarial assumptions used to determine expense were as follows:

	Pension						OPEB
Percentages	2014		2013		2012		2014		2013		2012
Discount rate		4.72%		3.78%		4.54%		4.47%		3.48%		4.36%
Expected return on plan assets		7.50%		7.50%		7.50%		N/A		N/A		N/A
Compensation increase		4.00%		3.43%		3.69%		N/A		N/A		N/A
Health care cost trend rate (employees under 65)		N/A		N/A		N/A		6.49%		6.64%		6.91%
Ultimate health care cost trend rate		N/A		N/A		N/A		4.50%		4.50%		4.50%
Year ultimate trend reached		N/A		N/A		N/A		2028		2028		2028

The discount rate was based on a yield curve 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 on pension plan assets, net of fees, was approximately 6% in 2014, 17% in 2013, and 13% in 2012.

Assumed health care cost trend rates have an effect on the expense and liabilities reported for health care plans. The assumed health care cost trend rate is based on historical rates and expected market conditions. The 2015 assumed health care cost trend rate for employees under 65 is 6.49%. It is assumed the rate will decrease gradually to an ultimate rate of 4.5% in 2028 and will remain at that level.

64

A one-percentage point change in the assumed health care cost trend rates would have the following effects on OPEB:

Millions	One % pt.  Increase		One % pt.  Decrease
Effect on total service and interest cost components	$	1	$	(1)
Effect on accumulated benefit obligation		19		(16)

Cash Contributions

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

	Pension
Millions	Qualified		Non-qualified		OPEB
2013	$	200	$	16	$	23
2014		200		33		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 2014 were voluntary and were made with cash generated from operations.

The non-qualified pension and OPEB plans are not funded and are not subject to any minimum regulatory funding requirements. Benefit payments for each year represent supplemental pension payments and claims paid for medical and life insurance. We anticipate our 2015 supplemental pension and OPEB payments will be made from cash generated from operations.

Benefit Payments

The following table details expected benefit payments for the years 2015 through 2024:

Millions	Pension		OPEB
2015	$	180	$	23
2016		186		23
2017		191		23
2018		196		23
2019		201		23
Years 2020 - 2024		1,069		107

Asset Allocation Strategy

Our pension plan asset allocation at December 31, 2014 and 2013, and target allocation for 2015, are as follows:

	Target		Percentage of Plan Assets  December 31,
	Allocation 2015		2014		2013
Equity securities		60% to 70%		68%		70%

The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to achieve our target average long-term rate of return of 7.5%. While we believe we can achieve a long-term average rate of return of 7.5%, we cannot be certain that the portfolio will perform to our expectations. Assets are strategically allocated among equity, debt, and other investments in order to achieve a diversification level that reduces fluctuations in investment returns. Asset allocation target ranges for

65

equity, debt, and other portfolios are evaluated at least every three years with the assistance of an independent 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. 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 plans’ assets in high quality debt securities. The average credit rating of the debt portfolio exceeded A+ as of December 31, 2014 and 2013. 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 years at both December 31, 2014 and 2013.

The investment of pension plan assets in securities issued by UPC is explicitly prohibited by the plan 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 (the Trustee). 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 real estate investments and bond investments registered with the Securities and Exchange Commission. The real estate investments are traded actively on public exchanges. The share prices for these investments are published at the close of each business day. The Plan’s holdings of real estate investments are classified as Level 1 investments. The bond investments are not traded publicly, but the underlying assets held in these funds are traded on active markets and the prices for these assets are readily observable. The Plan’s holdings in bond investments are classified as Level 2 investments.

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

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

Corporate Stock – This investment category consists of common and preferred stock issued by U.S. and non-U.S. corporations. Most common shares are traded actively on exchanges and price quotes for these shares are readily available. Common stock is classified as a Level 1 investment. Preferred shares included in this category are valued using a bid evaluation process with bid data provided by independent pricing sources. Preferred stock is classified as a Level 2 investment.

Venture Capital and Buyout Partnerships – This investment category is comprised of interests in limited partnerships that invest primarily in privately-held companies. 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 the application of public market multiples to private company cash flows, market transactions that provide valuation information for comparable companies, and other methods. The fair value recorded by the Plan is calculated using the net asset value (NAV) per share, which is derived from the valuation method described here. The Plan’s holdings of limited partnership interests are classified as Level 3 investments.

Real Estate Partnerships – Most of the Plan’s real estate investments are interests in partnerships or

66

other commingled funds. Valuations for the holdings in this category are not based on readily observable inputs and are primarily derived from property appraisals. The fair value recorded by the Plan is calculated using the NAV per share, which is derived from the valuation method described here. The Plan’s interests in real estate partnerships and other commingled funds are classified as Level 3 investments.

Common Trust and Other Funds – Common trust funds are comprised of shares or units in commingled funds that are not publicly traded. The underlying assets in these funds (U.S. stock funds, non-U.S. stock funds, commodity funds, and short term investment funds) 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.

This category also includes investments in limited liability companies that invest in publicly-traded convertible securities, commodities, and other assets. The limited liability company investments are funds that invest in both long and short positions in convertible securities, stocks, commodities, and fixed income securities. The underlying securities held by the funds are traded actively on exchanges and price quotes for these investments are readily available. Interests in the limited liability companies are classified as Level 2 investments.

As of December 31, 2014, the pension plan assets measured at fair value on a recurring basis were as follows:

Other Retirement Programs

401(k)/Thrift Plan – We provide a defined contribution plan (401(k)/thrift plan) to eligible non-union and union employees for whom we make matching contributions. We match 50 cents for each dollar contributed by employees up to the first six percent of compensation contributed. Our plan contributions were $19 million in 2014, $18 million in 2013, and $15 million in 2012.

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 $711 million in 2014, $670 million in 2013, and $644 million in 2012.

Collective Bargaining Agreements – Under collective bargaining agreements, we participate in multi-employer benefit plans that provide certain postretirement health care and life insurance benefits for eligible union employees. Premiums paid under these plans are expensed as incurred and amounted to $52 million in 2014, $57 million in 2013, and $62 million in 2012.

7. Other Income

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

Millions	2014 [a]		2013 [b]		2012
Rental income	$	96	$	106	$	83
Net gain on non-operating asset dispositions		69		32		29
Interest income		4		4		3
Non-operating environmental costs and other		(18)		(14)		(7)
Total	$	151	$	128	$	108

[a] Non-operating environmental costs and other includes $14 million related to the sale of a permanent easement.

[b] Rental income includes $17 million related to a land lease contract settlement.

8. Income Taxes

Components of income tax expense were as follows for the years ended December 31:

Millions	2014		2013		2012
Current tax expense:
Federal	$	2,029	$	1,738	$	1,335
State		239		199		153
Total current tax expense		2,268		1,937		1,488
Deferred tax expense:
Federal		667		659		760
State		136		119		120
Total deferred tax expense		803		778		880
Unrecognized tax benefits:

State		6		(1)		2
Total unrecognized tax benefits expense/(benefits)		92		(55)		7
Total income tax expense	$	3,163	$	2,660	$	2,375

69

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

Tax Rate Percentages	2014		2013		2012
Federal statutory tax rate		35.0%		35.0%		35.0%
State statutory rates, net of federal benefits		3.1		3.1		3.1
Deferred tax adjustments		-		(0.1)		(0.1)
Tax credits		(0.4)		(0.2)		(0.5)
Other		0.2		(0.1)		0.1
Effective tax rate		37.9%		37.7%		37.6%

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 assets relate to deductions that already have been claimed for financial reporting purposes but not for 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 (including bonus 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	2014		2013
Deferred income tax liabilities:
Property	$	(15,173)	$	(14,448)
Other		(411)		(260)
Total deferred income tax liabilities		(15,584)		(14,708)
Deferred income tax assets:
Accrued wages		74		71
Accrued casualty costs		228		223
Accrued stock compensation		69		66
Debt and leases		86		41
Retiree benefits		392		100
Credits		164		182
Other		168		130
Total deferred income tax assets	$	1,181	$	813
Net deferred income tax liability	$	(14,403)	$	(13,895)
Current portion of deferred taxes	$	277	$	268
Non-current portion of deferred taxes		(14,680)		(14,163)
Net deferred income tax liability	$	(14,403)	$	(13,895)

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 for purposes of estimating whether future taxable income will be sufficient to realize a deferred tax asset. In 2014 and 2013, there were no valuation allowances.

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.

70

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

Millions	2014		2013		2012
Unrecognized tax benefits at January 1	$	59	$	115	$	107
Increases for positions taken in current year		92		24		29
Increases for positions taken in prior years		21		15		4
Decreases for positions taken in prior years		(14)		(30)		(19)
Payments to and settlements with taxing authorities		(7)		(63)		-
Increases/(decreases) for interest and penalties		1		-		(4)
Lapse of statutes of limitations		(1)		(2)		(2)
Unrecognized tax benefits at December 31	$	151	$	59	$	115

We recognize interest and penalties as part of income tax expense. Total accrued liabilities for interest and penalties were $6 million at both December 31, 2014 and 2013. Total interest and penalties recognized as part of income tax expense (benefit) were $9 million for 2014, $7 million for 2013, and $(4) million for 2012.

Internal Revenue Service (IRS) examinations have been completed and settled for all years prior to 2009, and the statute of limitations bars any additional tax assessments. The IRS has completed their examinations and issued notices of deficiency for tax years 2009 through 2010. We disagree with many of their proposed adjustments, and we are at IRS Appeals for those years. Additionally, several state tax authorities are examining our state income tax returns for years 2006 through 2010.

In the fourth quarter of 2014, UPC and the IRS signed a closing agreement resolving all tax matters for tax years 2005-2008. The settlement had an immaterial effect on our income tax expense. In connection with the settlement, UPC paid $11 million in 2014.

In 2012, UPC and the IRS signed a closing agreement resolving all tax matters for tax years 1999-2004. The settlement had an immaterial effect on our income tax expense. In connection with the settlement, we received refunds of $8 million in 2013.

We do not expect our unrecognized tax benefits to change significantly in the next 12 months. At December 31, 2014, we had a net unrecognized tax benefit liability of $151 million. Of that amount, $6 million is classified as a current liability in the Consolidated Statement of Financial Position.

The portion of our unrecognized tax benefits that relates to permanent changes in tax and interest would reduce our effective tax rate, if recognized. The remaining unrecognized tax benefits relate to tax positions for which only the timing of the benefit is uncertain. Recognition of the tax benefits with uncertain timing 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	2014		2013		2012
Unrecognized tax benefits that would reduce the effective tax rate	$	33	$	34	$	41
Unrecognized tax benefits that would not reduce the effective tax rate		118		25		74
Total unrecognized tax benefits	$	151	$	59	$	115

9. Earnings Per Share

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

Millions, Except Per Share Amounts	2014		2013		2012
Net income	$	5,180	$	4,388	$	3,943
Weighted-average number of shares outstanding:
Basic		897.1		926.5		946.2
Dilutive effect of stock options		2.1		2.4		3.6
Dilutive effect of retention shares and units		1.9		2.6		3.1
Diluted		901.1		931.5		952.9
Earnings per share – basic	$	5.77	$	4.74	$	4.17
Earnings per share – diluted	$	5.75	$	4.71	$	4.14

Common stock options totaling 0.4 million, 0.5 million, and 1.1 million for 2014, 2013, and 2012, 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. Accumulated Other Comprehensive Income/(Loss)

Reclassifications out of accumulated other comprehensive income/(loss) were as follows (net of tax):

Millions	Defined  benefit  plans		Foreign  currency  translation		Derivatives		Total
Balance at January 1, 2014	$	(713)	$	(37)	$	-	$	(750)
Other comprehensive income/(loss) before reclassifications		10		(12)		-		(2)
Amounts reclassified from accumulated other comprehensive income/(loss) [a]		(458)		-		-		(458)
Net year-to-date other comprehensive income/(loss), net of taxes of $291 million		(448)		(12)		-		(460)
Balance at December 31, 2014	$	(1,161)	$	(49)	$	-	$	(1,210)
Balance at January 1, 2013	$	(1,149)	$	(36)	$	(1)	$	(1,186)
Other comprehensive income/(loss) before reclassifications		(1)		(1)		1		(1)
Amounts reclassified from accumulated other comprehensive income/(loss) [a]		437		-		-		437
Net year-to-date other comprehensive income/(loss), net of taxes of ($264) million		436		(1)		1		436
Balance at December 31, 2013	$	(713)	$	(37)	$	-	$	(750)

[a] The accumulated other comprehensive income/(loss) reclassification components are 1) prior service cost/(benefit) and 2) net actuarial loss which are both included in the computation of net periodic pension cost. See Note 6 Retirement Plans for additional details.

11. Accounts Receivable

Accounts receivable includes freight and other receivables reduced by an allowance for doubtful accounts. The allowance is based upon historical losses, credit worthiness of customers, and current economic conditions. At December 31, 2014, and 2013, our accounts receivable were reduced by $5 million and $1 million, respectively. Receivables not expected to be collected in one year and the associated allowances are classified as other assets in our Consolidated Statements of Financial

72

Position. At December 31, 2014, and 2013, receivables classified as other assets were reduced by allowances of $16 million and $22 million, respectively.

Receivables Securitization Facility – On July 29, 2014, we completed the renewal of our receivables securitization facility. The new $650 million, 3-year facility replaces the prior $600 million, 364-day facility. Under the facility, the Railroad sells most of its eligible third-party receivables to Union Pacific Receivables, Inc. (UPRI), a wholly-owned, bankruptcy-remote subsidiary that may subsequently transfer, without recourse, an undivided interest in accounts receivable to 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.

The amount outstanding under the facility was $400 million and $0 at December 31, 2014, and December 31, 2013, respectively. The facility was supported by $1.2 billion and $1.1 billion of accounts receivable as collateral at December 31, 2014, and December 31, 2013, respectively, which, as a retained interest, is included in accounts receivable, net in our Consolidated Statements of Financial Position.

The outstanding amount the Railroad is allowed to maintain under the facility, with a maximum of $650 million, may fluctuate based on the availability of eligible receivables and is directly affected by business volumes and credit risks, including receivables payment quality measures such as default and dilution ratios. If default or dilution ratios increase one percent, the allowable outstanding amount under the facility would not materially change.

The costs of the receivables securitization facility include interest, which will vary based on prevailing benchmark and commercial paper rates, program fees paid to participating banks, commercial paper issuing costs, and fees of participating banks for unused commitment availability. The costs of the receivables securitization facility are included in interest expense and were $4 million, $5 million and $3 million for 2014, 2013, and 2012, respectively.

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) for which lives 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 lives 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

74

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 lives 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. In addition, we determine if the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by our depreciation studies. Any deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the applicable classes of assets.

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. 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 track assets and other road properties, which is typically performed by our employees, and for track line expansion and other capacity projects. Costs that are directly attributable to capital projects (including overhead costs) 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.

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. These costs are allocated using appropriate statistical bases. Total expense for repairs and maintenance incurred was $2.4 billion for 2014, $2.3 billion for 2013, and $2.1 billion for 2012.

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.

14. 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.

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, 2014, and 2013, we were not required to provide collateral, nor had we received collateral, relating to our hedging activities.

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. As of December 31, 2014, and 2013, we had no interest rate fair value hedges outstanding.

Interest Rate Cash Flow Hedges – We report changes in the fair value of cash flow hedges in accumulated other comprehensive loss until the hedged item affects earnings. At December 31, 2014, and 2013, we had reductions of $0 and $1 million, respectively, recorded as an accumulated other comprehensive loss. As of December 31, 2014, and 2013, we had no interest rate cash flow hedges outstanding.

Earnings Impact – Our use of derivative financial instruments had no impact on pre-tax income for the years ended December 31, 2014, 2013, and 2012.

Fair Value of Financial Instruments – The fair value of our short- and long-term debt was estimated using a market value price model, which utilizes applicable U.S. Treasury rates along with current market quotes on comparable debt securities. All of the inputs used to determine the fair market value of the Corporation’s long-term debt are Level 2 inputs and obtained from an independent source. At December 31, 2014, the fair value of total debt was $13.0 billion, approximately $1.5 billion more than the carrying value. At December 31, 2013, the fair value of total debt was $10.2 billion, approximately $0.6 billion more than the carrying value. The fair value of the Corporation’s debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules. At both December 31, 2014, and 2013, approximately $163 million of debt securities contained call provisions that allow us to retire the debt instruments prior to final maturity, with the payment of fixed call premiums, or in certain cases, at par. The fair value of our cash equivalents approximates their carrying value due to the short-term maturities of these instruments.

2017		1,065
2018		578
2019		652
Thereafter		8,117
Total debt	$	11,480

Equipment Encumbrances – Equipment with a carrying value of approximately $2.8 billion and $2.9 billion at December 31, 2014, and 2013, respectively, served as collateral for capital leases and other types of equipment obligations in accordance with the secured financing arrangements utilized to acquire such railroad equipment.

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 – During the second quarter of 2014, we replaced our $1.8 billion revolving credit facility, which was scheduled to expire in May 2015, with a new $1.7 billion facility that expires in May 2019 (the facility). The facility is based on substantially similar terms as those in the previous credit facility. On December 31, 2014, we had $1.7 billion of credit available under the facility, which is designated for general corporate purposes and supports the issuance of commercial paper. We did not draw on either facility at any time during 2014. 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 credit ratings for our senior unsecured debt.

The facility requires that the Corporation maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing. At December 31, 2014, and December 31, 2013 (and at all times during the year), 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

77

leases, guarantees and unfunded and vested pension benefits under Title IV of ERISA. At December 31, 2014, the debt-to-net-worth coverage ratio allowed us to carry up to $42.4 billion of debt (as defined in the facility), and we had $11.6 billion of debt (as defined in the facility) outstanding at that date. Under our current capital plans, we expect to continue to satisfy the debt-to-net-worth coverage ratio; however, many factors beyond our reasonable control could affect our ability to comply with this provision in the future. The facility does not include any other financial restrictions, credit rating triggers (other than rating-dependent pricing), or any other provision that could require us to post collateral. The facility also includes a $125 million cross-default provision and a change-of-control provision.

During 2014, we did not issue or repay any commercial paper, and at December 31, 2014, and 2013, we had no commercial paper outstanding. Our revolving credit facility supports our outstanding commercial paper balances, and, unless we change the terms of our commercial paper program, our aggregate issuance of commercial paper will not exceed the amount of borrowings available under the facility.

Dividend Restrictions – Our revolving credit facility includes a debt-to-net worth covenant (discussed in the Credit Facilities section above) that, under certain circumstances, restricts the payment of cash dividends to our shareholders. The amount of retained earnings available for dividends was $15.4 billion and $16.3 billion at December 31, 2014, and 2013, respectively.

Shelf Registration Statement and Significant New Borrowings – Under our current shelf registration, we may issue, from time to time, any combination of debt securities, preferred stock, common stock, or warrants for debt securities or preferred stock in one or more offerings. We have no immediate plans to issue equity securities; however, we will continue to explore opportunities to replace existing debt or access capital through issuances of debt securities under our shelf registration, and, therefore, we may issue additional debt securities at any time.

During 2014, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
January 10, 2014	$300 million of 2.25% Notes due February 15, 2019
	$400 million of 3.75% Notes due March 15, 2024
	$300 million of 4.85% Notes due June 15, 2044
August 12, 2014	$350 million of 3.25% Notes due January 15, 2025
	$350 million of 4.15% Notes due January 15, 2045

We used the net proceeds from the offerings for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities include change-of-control provisions. At December 31, 2014, we had remaining authority to issue up to $1.15 billion of debt securities under our shelf registration.

Subsequent Event – In 2015, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
January 29, 2015	$250 million of 1.80% Notes due February 1, 2020
	$450 million of 3.375% Notes due February 1, 2035
	$450 million of 3.875% Notes due February 1, 2055

Proceeds from this offering are for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities include change-of-control provisions. This offering exhausted our current authority to issue debt securities under our existing shelf registration.

On February 5, 2015, the Board of Directors approved proceeding with a new shelf registration statement and authorized the issuance of up to $4.0 billion of debt securities.

Equipment Trust – On May 20, 2014, UPRR consummated a pass-through (P/T) financing, whereby a P/T trust was created, which issued $500 million of P/T trust certificates with a stated interest rate of 3.227%. The P/T trust certificates will mature on May 14, 2026. The proceeds from the issuance of the

78

P/T trust certificates (net of $3 million in transaction fees) were used to purchase equipment trust certificates to be issued by UPRR to finance the acquisition of 245 locomotives. The equipment trust certificates are secured by a lien on the locomotives.

Debt Exchange – On August 21, 2013, we exchanged $1,170 million of various outstanding notes and debentures due between 2016 and 2040 (the Existing Notes) for $439 million of 3.646% notes (the New 2024 Notes) due February 15, 2024 and $700 million of 4.821% notes (the New 2044 Notes) due February 1, 2044, plus cash consideration of approximately $280 million in addition to $8 million for accrued and unpaid interest on the Existing Notes. In accordance with ASC 470-50-40, Debt-Modifications and Extinguishments-Derecognition, this transaction was accounted for as a debt exchange, as the exchanged debt instruments are not considered to be substantially different. The cash consideration was recorded as an adjustment to the carrying value of debt, and the balance of the unamortized discount and issue costs from the Existing Notes is being amortized as an adjustment of interest expense over the terms of the New 2024 Notes and the New 2044 Notes. No gain or loss was recognized as a result of the exchange. Costs related to the debt exchange that were payable to parties other than the debt holders totaled approximately $9 million and were included in interest expense during the three months ended September 30, 2013.

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

Millions	Principal amount  exchanged

5.780% Notes due 2040		286
Total	$	1,170

Debt Redemption – On May 14, 2013, we redeemed all $40 million of our outstanding 5.65% Port of Corpus Christi Authority Revenue Refunding Bonds due December 1, 2022. The redemption resulted in an early extinguishment charge of $1 million in the second quarter of 2013.

Receivables Securitization Facility – As of December 31, 2014 and 2013, we recorded $400 million and $0 of borrowings under our receivables securitization facility, respectively, as secured debt. (See further discussion of our receivables securitization facility in Note 11).

16. Variable Interest Entities

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

We maintain and operate the assets based on contractual obligations within the lease arrangements, which set specific guidelines consistent within the railroad industry. As such, we have no control over activities that could materially impact the fair value of the leased assets. We do not hold the power to

79

direct the activities of the VIEs and, therefore, do not control the ongoing activities that have a significant impact on the economic performance of the VIEs. Additionally, we do not have the obligation to absorb losses of the VIEs or the right to receive benefits of the VIEs that could potentially be significant to the VIEs.

We are not considered to be the primary beneficiary and do not consolidate these VIEs because our actions and decisions do not have the most significant effect on the VIE’s performance and our fixed-price purchase options are not considered to be potentially significant to the VIEs. The future minimum lease payments associated with the VIE leases totaled $3.0 billion as of December 31, 2014.

17. Leases

We lease certain locomotives, freight cars, and other property. The Consolidated Statements of Financial Position as of December 31, 2014 and 2013 included $2,454 million, net of $1,210 million of accumulated depreciation, and $2,486 million, net of $1,092 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, 2014, were as follows:

Millions	Operating  Leases		Capital  Leases
2015	$	508	$	253
2016		484		249
2017		429		246
2018		356		224
2019		323		210
Later years		1,625		745
Total minimum lease payments	$	3,725	$	1,927
Amount representing interest		N/A		(407)
Present value of minimum lease payments		N/A	$	1,520

Approximately 95% of capital lease payments relate to locomotives. Rent expense for operating leases with terms exceeding one month was $593 million in 2014, $618 million in 2013, and $631 million in 2012. 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.

18. Commitments and Contingencies

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

Personal Injury – The cost of personal injuries to employees and others related to our activities is charged to expense based on estimates of the ultimate cost and number of incidents each year. We use an actuarial analysis to measure the expense and liability, including unasserted claims. The Federal Employers’ Liability Act (FELA) governs compensation for work-related accidents. Under FELA, damages are assessed based on a finding of fault through litigation or out-of-court settlements. We offer a comprehensive variety of services and rehabilitation programs for employees who are injured at work.

Our personal injury liability is not discounted to present value due to the uncertainty surrounding the timing of future payments. Approximately 93% of the recorded liability is related to asserted claims and approximately 7% is related to unasserted claims at December 31, 2014. Because of the uncertainty

80

surrounding the ultimate outcome of personal injury claims, it is reasonably possible that future costs to settle these claims may range from approximately $335 million to $368 million. We record an accrual at the low end of the range as no amount of loss within the range is more probable than any other. Estimates can vary over time due to evolving trends in litigation.

Our personal injury liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	294	$	334	$	368
Current year accruals		96		87		121
Changes in estimates for prior years		9		(38)		(58)
Payments		(64)		(89)		(97)
Ending balance at December 31	$	335	$	294	$	334
Current portion, ending balance at December 31	$	111	$	82	$	95

In conjunction with the liability update performed in 2014, we also reassessed our estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2014, and 2013.

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

• The ratio of future claims by alleged disease would be consistent with historical averages adjusted for inflation.

• 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, 2014. 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 $126 million to $135 million. We record an accrual at the low end of the range as no amount of loss within the range is more probable than any other.

Our asbestos-related liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	131	$	139	$	147
Accruals/(Credits)		1		2		(2)
Payments		(6)		(10)		(6)
Ending balance at December 31	$	126	$	131	$	139
Current portion, ending balance at December 31	$	8	$	9	$	8

In conjunction with the liability update performed in 2014, we also reassessed our estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2014, and 2013. The amounts recorded for asbestos-related liabilities and related insurance recoveries were based on currently known facts. However, future events, such as the number of new claims filed each year, average settlement costs, and insurance coverage issues, could cause the actual costs and insurance recoveries to be higher or lower than the projected amounts. Estimates also may vary in the future if strategies, activities, and outcomes of asbestos litigation materially change; federal and state laws governing asbestos litigation increase or decrease the probability or amount of compensation of

81

claimants; and there are material changes with respect to payments made to claimants by other defendants.

Environmental Costs – We are subject to federal, state, and local environmental laws and regulations. We have identified 270 sites at which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 29 sites that are the subject of actions taken by the U.S. government, 16 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 perform, with assistance of our consultants, environmental assessments on the property. We expense the cost of the assessments as incurred. We accrue the cost of remediation where our obligation is probable and such costs can be reasonably estimated. Our environmental liability is not discounted to present value due to the uncertainty surrounding the timing of future payments.

Our environmental liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	171	$	170	$	172
Accruals		56		58		48
Payments		(45)		(57)		(50)
Ending balance at December 31	$	182	$	171	$	170
Current portion, ending balance at December 31	$	60	$	53	$	50

The environmental liability includes future costs for remediation and restoration of sites, as well as ongoing monitoring costs, but excludes any anticipated recoveries from third parties. Cost estimates are based on information available for each site, financial viability of other potentially responsible parties, and existing technology, laws, and regulations. The ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties, site-specific cost sharing arrangements with other potentially responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs. Estimates of liability may vary over time due to changes in federal, state, and local laws governing environmental remediation. Current obligations are not expected to have a material adverse effect on our consolidated results of operations, financial condition, or liquidity.

Insurance – The Company has a consolidated, wholly-owned captive insurance subsidiary (the captive), that provides insurance coverage for certain risks including FELA claims and property coverage which are subject to reinsurance. The captive entered into annual reinsurance treaty agreements that insure workers compensation, general liability, auto liability and FELA risk. The captive cedes a portion of its FELA exposure through the treaty and assumes a proportionate share of the entire risk. The captive receives direct premiums, which are netted against the Company’s premium costs in other expenses in the Consolidated Statements of Income. The treaty agreements provide for certain protections against the risk of treaty participants’ non-performance, and we do not believe our exposure to treaty participants’ non-performance is material at this time. In the event the Company leaves the reinsurance program, the Company is not relieved of its primary obligation to the policyholders for activity prior to the termination of the treaty agreements. We record both liabilities and reinsurance receivables using an actuarial analysis based on historical experience in our Consolidated Statements of Financial Position.

Guarantees – At December 31, 2014, and 2013, we were contingently liable for $82 million and $299 million in guarantees. We have recorded liabilities of $0.3 million and $1 million for the fair value of these obligations as of December 31, 2014, and 2013, respectively. We entered into these contingent guarantees in the normal course of business, and they include guaranteed obligations related to our 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.

82

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.

Gain Contingency – UPRR and Santa Fe Pacific Pipelines (SFPP, a subsidiary of Kinder Morgan Energy Partners, L.P.) currently are engaged in a proceeding to resolve the fair market rent payable to UPRR commencing on January 1, 2004, for pipeline easements on UPRR rights-of-way (Union Pacific Railroad Company vs. Santa Fe Pacific Pipelines, Inc., SFPP, L.P., Kinder Morgan Operating L.P. “D” Kinder Morgan G.P., Inc., et al., Superior Court of the State of California for the County of Los Angeles, filed July 28, 2004). In February 2007, a trial began to resolve this issue, and in May 2012, the trial judge rendered an opinion establishing the fair market rent and entering judgment for back rent, including prejudgment interest. SFPP appealed the judgment. On November 5, 2014, the Second District Circuit Court of Appeal in California issued an opinion holding that UPRR was not entitled to collect rent from SFPP for easements on the portions of the property acquired solely through Federal government land grants issued during the 1800s. The Appellate Court also reversed the award of prejudgment interest and remanded the case to the trial court. A favorable final judgment may materially affect UPRR’s results of operations in the period of any monetary recoveries. Due to the uncertainty regarding the amount and timing of any recovery or any subsequent proceedings, we consider this a gain contingency and do not reflect any amounts in the Consolidated Financial Statements as of December 31, 2014.

19. Share Repurchase Program

Effective January 1, 2014, our Board of Directors authorized the repurchase of up to 120 million shares of our common stock by December 31, 2017, replacing our previous repurchase program. As of December 31, 2014, we repurchased a total of $12.6 billion of our common stock since the commencement of our repurchase programs in 2007. The table below represents shares repurchased in 2013 under our previous repurchase program, and shares repurchased in 2014 under the new program.

Remaining number of shares that may be repurchased under current authority								87,956,600

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

From January 1, 2015, through February 6, 2015, we repurchased 2.8 million shares at an aggregate cost of approximately $327 million.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

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

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

MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Union Pacific Corporation and Subsidiary Companies (the Corporation) is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). The Corporation’s internal control system was designed to provide reasonable assurance to the Corporation’s management and Board of Directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Corporation’s management assessed the effectiveness of the Corporation’s internal control over financial reporting as of December 31, 2014. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013). Based on our assessment, management believes that, as of December 31, 2014, the Corporation’s internal control over financial reporting is effective based on those criteria.

The Corporation’s independent registered public accounting firm has issued an attestation report on the effectiveness of the Corporation’s internal control over financial reporting. This report appears on the next page.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Union Pacific Corporation

Omaha, Nebraska

We have audited the internal control over financial reporting of Union Pacific Corporation and Subsidiary Companies (the Corporation) as of December 31, 2014, based on criteria established in Internal Control — Integrated Framework (2013) 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 the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. 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, 2014, based on the criteria established in Internal Control — Integrated Framework (2013) 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, 2014, of the Corporation and our report dated February 6, 2015 expressed an unqualified opinion on those financial statements and financial statement schedule.

These Standard Terms and Conditions apply to the Award of performance stock units granted pursuant to the Union Pacific Corporation 2013 Stock Incentive Plan (the “Plan”), which are evidenced by a Grant Notice that specifically refers to these Standard Terms and Conditions. In addition to these Standard Terms and Conditions, the performance stock units shall be subject to the terms of the Plan and the Long Term Plan, which are incorporated into these Standard Terms and Conditions by reference.

PERFORMANCE STOCK UNITS

1. TERMS OF PERFORMANCE STOCK UNITS

Union Pacific Corporation, a Utah corporation (the “Company”), has granted to the Participant named in the Grant Notice provided to said Participant herewith (the “Grant Notice”) an award of a number of performance stock units (the “Award” or the “Stock Units”) specified in the Grant Notice. Each Stock Unit represents the right to receive (i) one share of the Company’s common stock, $2.50 par value per share (the “Common Stock”) and (ii) a payment in cash equal to the amount of dividends that would have been payable on one share of Common Stock (“Dividend Equivalent Payments”), provided the applicable Performance Criteria described below have been satisfied. The Award is subject to the terms and conditions set forth in the Grant Notice, these Standard Terms and Conditions, the Plan and the Long Term Plan, each as amended from time to time. For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

2. VESTING OF PERFORMANCE STOCK UNITS

The Award shall not be vested as of the Grant Date set forth in the Grant Notice and shall be forfeitable until the end of the Restriction Period, unless otherwise provided under these Standard Terms and Conditions. After the end of the Restriction Period, subject to termination or acceleration as provided in these Standard Terms and Conditions, the Plan and the Long Term Plan, and to the extent the Performance Criteria described below have been satisfied, the Award shall become vested as of the Restriction Period Termination Date set forth in the Grant Notice with respect to that number of Stock Units determined by the Committee to be paid pursuant to the Award. Unless the Committee shall determine otherwise, a period in which the Participant is on a leave of absence during the Restriction Period in accordance with a leave of absence policy adopted by the Company shall count toward satisfaction of the Restriction Period.

3. PERFORMANCE CRITERIA

The Performance Criteria is annual Return on Invested Capital (“ROIC”). However, such Performance Criteria is of no force and effect unless and until the Company has operating income (“Operating Income”) in one or more of fiscal years 2015, 2016 or 2017. The definition and calculation of annual ROIC and Operating Income shall be determined in accordance with the Long Term Plan.

2

The Participant may earn Stock Units during the Restriction Period based on the Company’s satisfaction of the Performance Criteria in accordance with the ROIC targets and payout schedule approved by the Committee, subject to Section 6(ii) hereof and the Committee’s discretion under the Long Term Plan to determine the number of Stock Units payable with respect to the Award. For the fiscal year ending December 31, 2015, the Participant may earn up to one-third of the Stock Unit Target Award as shown on the Grant Notice based on the first fiscal year (2015) of ROIC performance achieved. For the fiscal year ending December 31, 2016, the Participant may earn up to a total of two-thirds of the Stock Unit Target Award as shown on the Grant Notice (less any Stock Units earned in the first fiscal year) based on the average of the first two fiscal years (2015 and 2016) of ROIC performance achieved. For the fiscal year ending December 31, 2017, the Participant may earn up to two times the Stock Unit Target Award as shown on the Grant Notice (less any Stock Units earned in the first two fiscal years) based on the average of all three fiscal years (2015, 2016, and 2017) of ROIC performance achieved.

4. DIVIDEND EQUIVALENT RIGHTS

For all dividend record dates occurring while the Participant is employed and between the date that Stock Units are earned and the earlier of the date the Stock Units are forfeited or the date that shares are delivered to the Participant, the Participant shall be entitled to receive Dividend Equivalent Payments for those Stock Units which have been earned in accordance with Section 3 hereof. For this purpose, Stock Units are earned in accordance with Section 3 hereof for a fiscal year on the date on which the Committee certifies in writing the ROIC performance level achieved for such fiscal year, provided the Company has Operating Income in that fiscal year, or for fiscal years 2016 and 2017, the previous fiscal year. Notwithstanding the foregoing:

(i) If the Participant earns Stock Units in accordance with Section 3 hereof that are payable to the Participant as specified in Section 6(ii) hereof, unless otherwise determined by the Committee, the Participant, the Participant’s estate or beneficiary, as applicable, shall further receive Dividend Equivalent Payments with respect to such Stock Units for all dividend record dates occurring after the Participant is Separated from Service or determined to be disabled under the provisions of an applicable long-term disability plan of the Company, through the date the shares are delivered as provided in and subject to the adjustment described in Section 6(ii) hereof; and

(ii) Unless otherwise determined by the Committee, if the Participant remains continuously employed with the Company, but is on a leave of absence during the Restriction Period in accordance with an applicable leave of absence policy adopted by the Company, for all dividend record dates occurring while the Participant is on such leave of absence and between the date that Stock Units are earned and the earlier of the date the Stock Units are forfeited or the date that shares are delivered to the Participant, the Participant shall be entitled to receive Dividend Equivalent Payments for those Stock Units which have been earned in accordance with Section 3 hereof.

Any such Dividend Equivalent Payments shall be made on the payment date established by the Board of Directors for the underlying dividend payments (such date to be on or after the date the corresponding Stock Units are earned); provided, however, that (i) if the Participant has elected to defer receipt of such Stock Units in accordance with the terms of the Deferred Compensation Plan of Union Pacific Corporation (the “Deferred Compensation Plan”), Dividend Equivalent Payments with respect to such earned and deferred Stock Units which relate to dividends paid on and after the date of the deferral of such Stock Units (i.e., the date that the Stock Units would have been payable to the Participant under the Plan had such Stock Units not been deferred under the Company’s Deferred Compensation Plan) shall be reinvested as part of the Award Account under the Company’s Deferred Compensation Plan, and shall be deferred for payment at the same time as the Award Account is paid under the terms of the Company’s Deferred Compensation Plan and (ii) if such Dividend Equivalent Payments relate to Stock Units for which payment is delayed as described in Section 6(i) hereof, on the date such Stock Units are paid.

5. RESTRICTIONS

Unless provided otherwise by the Committee, the following restrictions apply to the Stock Units:

(i) The Participant shall be entitled to delivery of the shares of Common Stock as specified in Section 6 hereof;

(ii) None of the Stock Units may be sold, transferred, assigned, pledged, or otherwise encumbered or disposed of;

(iii) The Participant’s right to receive Dividend Equivalent Payments shall terminate without further obligation on the part of the Company at the earlier of the Participant’s Separation from Service with the Company, except as provided in Section 4(ii) and Section 6(ii) hereof, or the Participant’s receipt of Common Stock under Section 6 hereof;

(iv) All of the Stock Units shall be forfeited and all of the Participant’s rights to such Stock Units and the right to receive Common Stock shall terminate without further obligation on the part of the Company in the event of the Participant’s Separation from Service with the Company without having a right to delivery of shares of Common Stock under Section 6 hereof; and

(v) Any Stock Units not earned as of the Restriction Period Termination Date shall be forfeited and all of the Participant’s rights to such Stock Units shall terminate without further obligation on the part of the Company.

6. ACCELERATION/LAPSE OF RESTRICTION PERIOD

Unless provided otherwise by the Committee, the Stock Units shall be treated as follows:

(i) Following the end of the Restriction Period and provided the Participant has remained continuously employed by the Company through the Restriction Period Termination Date and absent any Change of Control before the Restriction Period Termination Date in which the acquiring or surviving company in the transaction does not assume or continue the outstanding Stock Units, shares of Common Stock equal to the number of Stock Units which are earned (as determined by the Committee) based on the achievement of the applicable Performance Criteria shall be delivered to the Participant (through the Participant’s account at the Company’s third party stock plan administrator, if applicable) free of all restrictions, provided the Company has Operating Income in one or more of the fiscal years 2015, 2016 or 2017. The payment of the Stock Units under this Section 6(i) shall be made to the Participant within thirty (30) days of the Restriction Period Termination Date. Notwithstanding the foregoing, (A) the Company shall not be obligated to deliver any shares of Common Stock during any period when the Company determines that the delivery of shares hereunder would violate any federal, state or other applicable laws and/or may issue shares subject to any restrictive legend that, as determined by the Company’s counsel, is necessary to comply with securities or other regulatory requirements and (B) the date on which shares are delivered to the Participant (and any Dividend Equivalent Payment thereon) may include a delay to provide the Company such time as it determines appropriate to calculate and address tax withholding and/or other administrative matters; provided, however, that delivery of shares of Common Stock underlying the Stock Units (and any Dividend Equivalent Payments on such Stock Units or, if such Dividend Equivalent Payments are invested in additional Stock Units at the Company’s discretion, the shares of Common Stock underlying such additional Stock Units) shall in no event be later than the last day of the calendar year that includes the Restriction Period Termination Date.

(ii) If the Participant: (A) has a Separation from Service with the Company due to (1) death or (2) retiring after having attained age 62 with 10 years of service under the provisions of the Company’s pension plan (“Retirement”) (including a Separation from Service described in Section

4

6(iv) hereof on or after the date the Participant satisfies the age and service criteria for Retirement); or (B) is determined to be disabled under the provisions of an applicable long-term disability plan of the Company (“Disability”) (each a “Lapse Event”), prior to the Restriction Period Termination Date and prior to a Change in Control in which the acquiring or surviving company in the transaction does not assume or continue the outstanding Stock Units, the Participant, the Participant’s estate or the Participant’s beneficiary, as applicable (each a “Payee”), shall be entitled to receive shares of Common Stock equal to the number of Stock Units which are earned (as determined by the Committee) based on the average of all three fiscal years (2015, 2016 and 2017) of the applicable Performance Criteria achieved prorated based on the number of fiscal years in the Restriction Period during which the Participant remained continuously employed by the Company until September 30^th of that year (e.g., if the Participant’s Lapse Event occurs on or after September 30, 2015, then the Payee would be entitled to receive payment for 33 1/3% of the earned Stock Units; if the Participant’s Lapse Event occurs on or after September 30, 2016, then the Payee would be entitled to receive payment for 66 2/3% of the earned Stock Units; and if the Participant’s Lapse Event occurs on or after September 30, 2017, then the Payee would be entitled to receive payment for 100% of the earned Stock Units), provided that the Company has Operating Income in one or more of the fiscal years 2015, 2016 or 2017. The Payee shall be entitled to receive Dividend Equivalent Payments respecting all Stock Units earned in accordance with Section 3 hereof through the end of the fiscal year ending before the Participant’s Lapse Event for all dividend record dates occurring after the Participant’s Lapse Event (or, if later, the date the Stock Units for a fiscal year are earned) and thereafter during the Restriction Period until the Payee receives Common Stock under this Section 6(ii), notwithstanding the Participant’s Lapse Event. The Committee shall adjust the total amount of such Dividend Equivalent Payments made to the Payee and/or the total number of shares of Common Stock paid to the Payee following the end of the Restriction Period so that the total amount of such Dividend Equivalent Payments made to the Payee does not exceed the amount that would have been made based on the number of Stock Units which are earned as set forth in this Section 6(ii). The payment of the Stock Units earned under this Section 6(ii) shall be made within thirty (30) days of the Restriction Period Termination Date, but in no event later than the last day of the calendar year that includes the Restriction Period Termination Date. A Participant who has a Lapse Event and subsequently returns to employment with the Company before the end of the Restriction Period shall not be eligible to earn additional Stock Units beyond those described in this Section 6(ii).

(iii) Upon the occurrence of a Change in Control, prior to the termination of the Participant’s employment for any reason, in which the acquiring or surviving company in the transaction does not assume or continue the outstanding Stock Units and such Change in Control occurs prior to the Restriction Period Termination Date, shares of Common Stock equal to the number of Stock Units which are earned (as determined by the Committee) based on achievement of the applicable Performance Criteria through the end of each fiscal year ending prior to the occurrence of such Change in Control and through the end of the most recent fiscal quarter ending prior to the date of the Change in Control shall be delivered to the Participant (through the Participant’s account at the Company’s third party administrator, if applicable) free of all restrictions, provided the Company has Operating Income in one or more of the calendar years 2015, 2016 or 2017 and further provided that any such calendar year precedes the calendar year in which the Change in Control occurs. No additional Stock Units granted as part of the Award may be earned following the Change in Control. Shares of Common Stock to which the Participant is entitled pursuant to this Section 6(iii) shall be delivered as soon as practicable following the date on which the Change in Control occurs, but in no event later than two and one-half (2 ¹/₂) months following the end of the calendar year that includes the date on which the Change in Control occurs.

(iv) If the Participant incurs a Separation from Service because such Participant’s employment is involuntarily terminated by the Company (other than a termination as a result of the Participant’s Disability, cause or gross misconduct as determined by the Committee), within twenty-four (24) months following a Change in Control in which the acquiring or surviving company in the transaction assumes or continues the outstanding Stock Units and such

5

Separation from Service occurs prior to the Restriction Period Termination Date and prior to the Participant having satisfied the age and service criteria for Retirement prior to such Separation from Service, shares of Common Stock equal to the number of Stock Units which are earned (as determined by the Committee) based on achievement of the applicable Performance Criteria through the end of each fiscal year ending prior to the occurrence of such Change in Control and through the end of the most recent fiscal quarter ending prior to the date of the Change in Control shall be delivered to the Participant (through the Participant’s account at the Company’s third party administrator, if applicable) free of all restrictions, provided the Company has Operating Income in one or more of the calendar years 2015, 2016 or 2017 and further provided that any such calendar year precedes the calendar year in which the Change in Control occurs. The payment of the Stock Units under this Section 6(iv) shall be made as soon as practicable following the Participant’s Separation from Service, but in no event later than two and one-half (2 ¹/₂)  months following the end of the calendar year that includes the date on which the Separation from Service occurs.

(v) Except as otherwise provided in this Section 6, all of the Stock Units shall be forfeited and all of the Participant’s rights to such Stock Units shall terminate without further obligation on the part of the Company unless the Participant remains in the continuous employment of the Company (such continuous employment shall, for this purpose, include a period of time during which the Participant is absent from active employment in accordance with a leave of absence policy adopted by the Company) until the earlier of the Restriction Period Termination Date or a Change in Control in which the acquiring or surviving company in the transaction does not assume or continue the outstanding Stock Units. Notwithstanding the foregoing, the Committee may, if it finds that the circumstances in the particular case so warrant, allow a Participant who ceases to be so continuously employed and has a Separation from Service prior to the earlier of the Restriction Period Termination Date or such Change in Control to retain some or all of the Stock Units which are earned (as determined by the Committee) based on achievement of the applicable Performance Criteria through the end of the fiscal year ending prior to the year in which the Participant incurs such Separation from Service, provided the Company has Operating Income in one or more of the fiscal years 2015, 2016 or 2017 and further provided that any such fiscal year precedes the year in which the Participant Separates from Service. In such event, the payment of the Stock Units under this Section 6(v) shall be as soon as practicable following the date on which the Committee authorizes such payment, but in no event later than two and one-half (2 ¹/₂) months following the end of the calendar year that includes the date on which the Participant’s Separation from Service occurs.

(vi) Notwithstanding the foregoing, the Participant may elect to defer receipt of payment of shares underlying the Stock Units to the extent and according to the terms, if any, provided by the Deferred Compensation Plan. If the Participant does so elect to defer payment of shares underlying the Stock Units, such payments will be made in accordance with the Deferred Compensation Plan.

PROTECTION OF CONFIDENTIALITY

By electronically accepting the Award and these Standard Terms and Conditions, the Participant acknowledges and agrees to the following.

7. CONFIDENTIAL INFORMATION; TRADE SECRETS

The Participant acknowledges that the Company regards certain information relating to its business and operations as confidential. This includes all confidential and proprietary information concerning the assets, business or affairs of the Company or any customers thereof (“Confidential Information”). The Participant’s electronic signature also acknowledges that the Company has certain information that derives economic value from not being known to the general public or to others who could obtain economic value from its disclosure or use, which the Company takes reasonable efforts to protect the secrecy of (“Trade Secrets”).

6

8. TYPES OF CONFIDENTIAL INFORMATION OR TRADE SECRETS

The Participant acknowledges that he or she developed or has had and will in the future continue to have access to one or more of the following types of Confidential Information or Trade Secrets: information about rates or costs; customer or supplier agreements and negotiations; business opportunities; scheduling and delivery methods; business and marketing plans; financial information or plans; communications within the attorney-client privilege or other privileges; operating procedures and methods; construction methods and plans; proprietary computer systems design, programming or software; strategic plans; succession plans; proprietary company training programs; employee performance, compensation or benefits; negotiations or strategies relating to collective bargaining agreements and/or labor disputes; and internal or external claims or complaints regarding personal injuries, employment laws or policies, environmental protection, or hazardous materials. The Participant agrees that any unauthorized disclosures by him or her to any third party of such Confidential Information or Trade Secrets would constitute gross misconduct.

9. AGREEMENT TO MAINTAIN CONFIDENTIAL INFORMATION

The Participant agrees that he or she will not, unless he or she receives prior written consent from the senior human resources officer or such other person designated by the Company (hereinafter collectively referred to as the “Sr. HR Officer”), or unless ordered by a court or government agency, (i) divulge, use, furnish or disclose to any subsequent employer or any other person, whether or not a competitor of the Company, any Confidential Information or Trade Secrets, or (ii) retain or take with him or her when he or she leaves the Company any property of the Company or any documents (including any electronic or computer records) relating to any Confidential Information or Trade Secrets.

10. PRIOR NOTICE OF EMPLOYMENT, ETC

(i) The Participant acknowledges that if he or she become an employee, contractor, or consultant for any other person or entity engaged in the Business of the Company as defined in Section 12, this would create a substantial risk that he or she would, intentionally or unintentionally, disclose or rely upon the Company’s Confidential Information or Trade Secrets for the benefit of the other railroad to the detriment of the Company. The Participant further acknowledges that such disclosures would be particularly damaging if made shortly after he or she leaves the Company. Therefore, by electronically accepting the Award and these Standard Terms and Conditions, the Participant agrees that for a period of one-year after he or she leaves the Company, before accepting any employment or affiliation with another railroad he or she will give written notice to the Sr. HR Officer of his or her intention to accept such employment or affiliation. The Participant also agrees to confer in good faith with the Sr. HR Officer concerning whether his or her proposed employment or affiliation could reasonably be expected to be performed without improper disclosure of Confidential Information or Trade Secrets.

(ii) If the Sr. HR Officer and the Participant are unable to reach agreement on this issue, he or she agrees to submit this issue to arbitration, to be conducted under the rules of the American Arbitration Association, for final resolution. The Participant also agrees that he or she will not begin to work for another person or entity engaged in the Business of the Company as defined in Section 12, until the Sr. HR Officer or an arbitrator has determined that such employment could reasonably be expected to be performed without improper disclosure of the Company’s Confidential Information or Trade Secrets.

11. FAILURE TO COMPLY

The Participant agrees that, if he or she fails to comply with any of the promises that he or she made in Section 9 or 10 above, he or she will be required to immediately deliver to the Company any shares of Common Stock (or the market value of any shares of Common Stock received)

7

which he or she received at any time from 180 days prior to the earlier of (i) the date when he or she leaves the Company or (ii) the date he or she fails to comply with any such promise made in Section 9 or 10, to 180 days after the date when the Company learns that he or she has not complied with any such promise. The Participant agrees that he or she will deliver such shares of Common Stock (or the cash equivalent) to the Company on such terms and conditions as may be required by the Company. The Participant further agrees that the Company will be entitled to enforce this repayment obligation by all legal means available, including, without limitation, to set off the market value of any such shares of Common Stock against any amount that might be owed to him or her by the Company. The Participant acknowledges that the Company would not have awarded the Participant the shares of Common Stock granted to him or her under the Award absent the Participant’s agreement to be bound by the promises made in Sections 9 and 10 above.

NO DIRECT COMPETITION

By electronically accepting the Award and these Standard Terms and Conditions, the Participant acknowledges and agrees to the following.

12. NON-SOLICITATION OF CUSTOMERS; NON-COMPETITION

The Participant agrees that for a period of one year following his or her departure from the Company, he or she will not (directly or in association with others) call on or solicit any of the Company’s customers with whom he or she had personal contact while he or she was employed by the Company, for the purpose of providing the customers with goods and/or services similar in nature to those provided by the Company in its Business as defined below. The Participant further agrees that for the same time period, he or she will not, directly or indirectly, engage in any activity which is the same as or competitive with the Business (as defined below) including, without limitation, engagement as an officer, director, proprietor, employee, partner, investor (other than as a holder of less than 2% of the outstanding capital stock of a publicly traded corporation), guarantor, consultant, advisor, agent, sales representative or other participant, in any market in which the Company conducts its Business. For purposes of these Standard Terms and Conditions, the term “Business” means the transportation of goods in interstate commerce and related services in or through or for any state in which the Company or any of its affiliates provides such services directly or indirectly and any other activity that supports such operations including by the way of example but not limitation, marketing, information systems, logistics, technology development or implementation, terminal services and any other activity of the Company or any of its affiliates. This Section 12 is not intended to prevent the Participant from engaging in any activity that is not the same as or competitive with the Business. The Participant acknowledges that the Company would not have awarded him or her the shares of Common Stock granted under the Award absent his or her agreement to be bound by the promises made in this Section 12.

13. ACKNOWLEDGMENT; INJUNCTIVE RELIEF

The Participant acknowledges that he or she has carefully read and considered all these Standard Terms and Conditions, including the restraints imposed upon him or her pursuant to Sections 9, 10 and 12. The Participant also agrees that each of the restraints contained herein is necessary for the protection of the goodwill, Confidential Information, Trade Secrets and other legitimate interests of the Company; that each and every one of these restraints is reasonable in respect to subject matter, length of time and geographic area; and that these restraints, individually or in the aggregate, will not prevent him or her from obtaining other suitable employment during the period in which he or she are bound by such restraints. The Participant further acknowledges that, were he or she to breach any of the covenants contained in Sections 9, 10 and 12, the damage to the Company would be irreparable. The Participant therefore agrees that the Company, in addition to any other remedies available to it, including, without

8

limitation, the remedies set forth in Sections 11 and 14, shall be entitled to injunctive relief against his or her breach or threaten breach of said covenants. The Participant and the Company further agree that, in the event that any provision of Sections 9, 10 and 12 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, such provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law.

14. VIOLATION OF PROMISES

The Participant agrees that if he or she violates any of his or her promises in Section 12, then he or she will be required to immediately deliver to the Company any shares of Common Stock (or the fair market value thereof) granted to him or her by the Grant Notice which he or she received at any time from 180 days prior to the date when he or she leaves the Company to 180 days after the date when the Company learns that he or she has not complied with the promises he or she made in Section 12. The Participant agrees that he or she will deliver such shares of Common Stock (or the fair market value thereof) to the Company on such terms and conditions as may be required by the Company. The Participant further agrees that the Company will be entitled to enforce this repayment obligation by all legal means available, including, without limitation, to set off the market value of any such shares of Common Stock against any amount that might be owed to him or her by the Company.

GENERAL

15. ARBITRATION

The Participant agrees and the Company agrees that any controversy, claim, or dispute arising out of or relating to this Award or the breach of any of these terms and conditions, or arising out of or relating to his or her employment relationship with the Company or any of its affiliates, or the termination of such relationship, shall be resolved by binding arbitration before a neutral arbitrator under the rules set forth in the Federal Arbitration Act, except for claims by the Company relating to his or her breach of any of the employee covenants set forth in Paragraphs 7, 8, 9, 10 or 12 above. By way of example only, claims subject to this agreement to arbitrate include claims litigated under federal, state and local statutory or common law, such as the Age Discrimination in Employment Act, Title VII of the Civil Rights Act of 1964, as amended, including the Civil Rights Act of 1994, the Americans with Disabilities Act, the law of contract and the law of tort. The Participant and the Company agree that such claims may be brought in an appropriate administrative forum, but at the point at which the Participant or the Company seek a judicial forum to resolve the matter, this agreement for binding arbitration becomes effective, and the Participant and the Company hereby knowingly and voluntarily waive any right to have any such dispute tried and adjudicated by a judge or jury. The foregoing not to the contrary, the Company may seek to enforce the employee covenants set forth in Paragraphs 7, 8, 9, 10 or 12 above, in any court of competent jurisdiction.

This agreement to arbitrate shall continue in full force and effect despite the expiration or termination of these Standard Terms and Conditions or the Participant’s employment relationship with the Company or any of its affiliates. The Participant and the Company agree that any award rendered by the arbitrator shall be final and binding and that judgment upon the final award may be entered in any court having jurisdiction thereof. The arbitrator may grant any remedy or relief that the arbitrator deems just and equitable, including any remedy or relief that would have been available to the Participant, the Company or any of its affiliates had the mater been heard in court. All expenses of the arbitration, including the required travel and other expenses of the arbitrator and any witnesses, and the costs relating to any proof produced at the direction of the arbitrator, shall be borne equally by the Participant and the Company unless otherwise mutually agreed or unless the arbitrator directs otherwise in the award. The arbitrator’s compensation shall be borne equally by the Participant and the Company unless otherwise mutually agreed or unless the law provides otherwise.

If any provision of these Standard Terms and Conditions is, becomes, or is deemed to be invalid, illegal, or unenforceable in any jurisdiction, such provision shall be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of the Company, it shall be stricken and the remainder of these Standard Terms and Conditions shall remain in force and effect.

17. CHOICE OF LAW; JURISDICTION

All questions pertaining to the construction, regulation, validity, and effect of these Standard Terms and Conditions shall be determined in accordance with the laws of the State of Utah, without regard to the conflict of laws doctrine. The Company and the Participant hereby consent and submit to the personal jurisdiction and venue of any state or federal court located in the county of Salt Lake City within the State of Utah for resolution of any and all claims, causes of action or disputes arising out of or related to these Standard Terms and Conditions. Sections 10(ii) and 12 shall not apply to employees who are subject to California law.

18. AMENDMENTS

The Plan and these Standard Terms and Conditions may be amended or altered by the Committee or the Company’s Board of Directors to the extent provided in the Plan.

19. RESTRICTIONS ON RESALES OF SHARES

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any Common Stock issued in respect of vested Stock Units, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other holders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

20. INCOME TAXES

The Company shall not deliver shares in respect of any Stock Units unless and until the Participant has made satisfactory arrangements to satisfy all applicable tax withholding obligations. Unless the Participant pays the tax withholding obligations to the Company by cash or check in connection with the delivery of the Common Stock, withholding may be effected, at the Company’s option, by withholding Common Stock issuable in connection with the vesting of the Stock Units (provided that shares of Common Stock may be withheld only to the extent that such tax withholding will not result in adverse accounting treatment for the Company). The Participant acknowledges that the Company shall have the right to deduct any taxes required to be withheld by law in connection with the delivery of the Stock Units from any amounts payable by it to the Participant (including, without limitation, future cash wages).

21. NON-TRANSFERABILITY OF AWARD

The Participant understands, acknowledges and agrees that, except as otherwise provided in the Plan, the Stock Units may not be sold, assigned, transferred, pledged or otherwise directly or indirectly encumbered or disposed of prior to the payment of the Common Stock to the Participant as provided in Section 6 hereof.

22. RESTATEMENTS OF FINANCIAL RESULTS

By electronically accepting this Award, the Participant agrees that he or she will return such shares of Common Stock (or the fair market value thereof) to the Company as determined by the Committee in its exclusive discretion, which shall be final, conclusive and binding upon the Company and the Participant. The Committee will exercise its discretion only in the event that the Committee’s certification of the level of ROIC was based on financial results subsequently revised by a restatement of such financial results and only to the extent that such restated financial results would have entitled the Participant to a lesser award of Common Stock under the Performance Criteria.

23. LIMITATION OF INTEREST IN SHARES SUBJECT TO RESTRICTED STOCK UNITS

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan, the Long Term Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common Stock, if any, as shall have been issued to such person upon vesting of the Stock Units. Nothing in the Plan, the Long Term Plan, the Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue in the Company’s employ or service nor limit in any way the Company’s right to terminate the Participant’s employment at any time for any reason.

24. OTHER AGREEMENTS SUPERSEDED

The Grant Notice, these Standard Terms and Conditions, the Plan and the Long Term Plan constitute the entire understanding between the Participant and the Company regarding the Stock Units. Any prior agreements, commitments or negotiations concerning the Stock Units are superseded.

STOCK UNITS

These Standard Terms and Conditions apply to the Award of stock units granted pursuant to the Union Pacific Corporation 2013 Stock Incentive Plan (the “Plan”), which are evidenced by a Grant Notice that specifically refers to these Standard Terms and Conditions. In addition to these Standard Terms and Conditions, the stock units shall be subject to the terms of the Plan and, if applicable, the Key Employee Continuity Plan, which are incorporated into these Standard Terms and Conditions by this reference. Capitalized terms not otherwise defined herein shall have the meaning set forth in the Plan.

STOCK UNITS

1. TERMS OF STOCK UNITS

Union Pacific Corporation, a Utah corporation (the “Company”), has granted to the Participant named in the Grant Notice provided to said Participant herewith (the “Grant Notice”) an award of a number of stock units (the “Award” or the “Stock Units”) specified in the Grant Notice. Each Stock Unit represents the right to receive (i) one share of the Company’s common stock, $2.50 par value per share (the “Common Stock”) and (ii) a payment in cash equal to the amount of dividends that would have been payable on one share of Common Stock from time to time (“Dividend Equivalent Payments”), upon the terms and subject to the conditions set forth in the Grant Notice, these Standard Terms and Conditions, the Plan and, if applicable, the Key Employee Continuity Plan, each as amended from time to time. For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

2. VESTING OF STOCK UNITS

The Award shall not be vested as of the Grant Date set forth in the Grant Notice and shall be forfeitable unless and until otherwise vested pursuant to the terms of the Grant Notice and these Standard Terms and Conditions, the terms of the Plan and, if applicable, the Key Employee Continuity Plan. After the end of the Restriction Period, subject to termination or acceleration as provided in these Standard Terms and Conditions, the Plan and, if applicable, the Key Employee Continuity Plan, the Award shall become vested as of the Restriction Period Termination Date described in the Grant Notice with respect to that number of Stock Units as set forth in the Grant Notice. Unless the Compensation and Benefits Committee of the Company’s Board of Directors (the “Committee”) shall determine otherwise, a period of time in which the Participant is on a leave of absence during the Restriction Period in accordance with a leave of absence policy adopted by the Company or a Subsidiary shall count toward satisfaction of the Restriction Period.

3. DIVIDEND EQUIVALENT RIGHTS

The Participant will have the rights of a shareholder only after shares of Common Stock have been issued to the Participant following the Restriction Period Termination Date as described in the Grant Notice (or such earlier date as otherwise provided in Section 5(i) or Section 5(iii) hereof) and satisfaction of all other conditions to the issuance of those shares. Stock Units shall not entitle the Participant to any rights of a shareholder of Common Stock and there are no voting rights with respect to the Stock Units. During the Restriction Period and during any period following the end of the Restriction Period in which delivery of shares of Common Stock is: (i) deferred pursuant to the Company’s Deferred Compensation Plan; or (ii) delayed in accordance with Section 5(i) hereof; unless otherwise determined by the Committee, the Participant shall be entitled to receive Dividend Equivalent Payments. Such Dividend Equivalent Payments shall be made on the payment date established by the Board of Directors for the underlying dividend payments; provided, however, that (i) if the Participant has elected to defer receipt of the Stock Units in accordance with the terms of the Company’s Deferred Compensation Plan, Dividend Equivalent Payments with respect to such deferred Stock Units which relate to dividends paid on

2

and after the date of the deferral of such Stock Units (i.e., the date that the Stock Units would have been payable to the Participant under the Plan had such Stock Units not been deferred under the Company’s Deferred Compensation Plan) shall be reinvested as part of the Award Account under the Company’s Deferred Compensation Plan, and shall be deferred for payment at the same time as the Award Account is paid under the terms of the Company’s Deferred Compensation Plan; and (ii) if such Dividend Equivalent Payments relate to Stock Units who payment is delayed as described in Section 5(i) hereof, on the date such Stock Units are paid. Except as provided above, a Participant’s right to receive Dividend Equivalent Payments shall terminate without further obligation on the part of the Company at the earliest of the Participant’s Separation from Service with the Company or a Subsidiary, payment of the Common Stock under Section 5 hereof or at the Restriction Period Termination Date, except that:

(A) in the event the Participant remains continuously employed with the Company or a Subsidiary until September 30, 2015, and is age 62 with 10 years of service under the provisions of the Company’s or a Subsidiary’s pension plan at any time during the Restriction Period during the Participant’s period of continuous employment (satisfaction of both the September 30, 2015 continuous employment requirement and age and service requirements is known as “Retirement Status”), such Participant shall be entitled to receive Dividend Equivalent Payments in accordance with this Section 3 hereof until the earlier of the Restriction Period Termination Date or payment of the Common Stock under Section 5 hereof, notwithstanding any Separation from Service with the Company or a Subsidiary on or after attaining Retirement Status; and

(B) in the event the Participant remains continuously employed with the Company or a Subsidiary, but is on a leave of absence during the Restriction Period in accordance with a leave of absence policy adopted by the Company or a Subsidiary, such Participant shall be entitled to receive Dividend Equivalent Payments in accordance with this Section 3 hereof during the period of such leave of absence until the earlier of the date that is the end of such leave of absence, the Restriction Period Termination Date or payment of the Common Stock under Section 5 hereof, notwithstanding any Separation from Service with the Company or a Subsidiary as a result of such leave of absence.

4. ACCELERATION/LAPSE OF RESTRICTION PERIOD

Unless provided otherwise by the Committee, the Stock Units shall be treated as follows in connection with the Participant’s Separation from Service:

(i) If the Participant has a Separation from Service prior to the Restriction Period Termination Date by reason of the Participant’s death, the Stock Units shall immediately vest, all restrictions applicable to such Stock Units shall lapse and such Stock Units shall be paid in full to the Participant’s beneficiary or estate, as the case may be, in accordance with Section 5 hereof.

(ii) In the event the Participant is determined to be disabled under the provisions of the Company’s or a Subsidiary’s long-term disability plan, the Stock Units shall immediately vest, all restrictions applicable to such Stock Units shall lapse and such Stock Units shall be paid in full in accordance with Section 5 hereof.

(iii) If the Participant incurs a Separation from Service because such Participant’s employment is involuntarily terminated by the Company or any of its Subsidiaries (other than a termination as a result of disability, cause or gross misconduct as determined by the Committee), within two (2) years following a Change in Control (as defined in the Plan), the Stock Units shall immediately vest and the remaining restrictions with respect to the Stock Units, including any remaining Restriction Period, shall lapse and such Stock Units shall be paid in full in accordance with Section 5 hereof.

3

(iv) In the event of a Change in Control prior to the Restriction Period Termination Date in which the acquiring or surviving company in the transaction does not assume or continue the Stock Units upon the Change in Control, the Restriction Period and all other restrictions applicable to such Stock Units shall lapse immediately prior to the Change in Control and such Stock Units shall be paid in accordance with Section 5 hereof.

(v) In the event the Participant has attained Retirement Status (within the meaning of Section 3(A) hereof) at any time during the Restriction Period that is on or after September 30, 2015, and during the Participant’s period of continuous employment, the Restriction Period shall lapse on the date the Participant attains Retirement Status and such Stock Units shall be paid in accordance with Section 5 hereof.

(vi) Notwithstanding the foregoing paragraphs (i) through (v), if the Participant is an Eligible Employee (within the meaning of the Key Employee Continuity Plan) in the Key Employee Continuity Plan and incurs a Severance within the meaning of the Key Employee Continuity Plan, the Participant’s Stock Units shall vest and be paid in accordance with the terms and conditions of the Key Employee Continuity Plan, including without limitation the requirement that the Participant execute an appropriate general release of employment-related claims.

(vii) Except as otherwise provided in this Section 4 hereof, all of the Stock Units shall be forfeited and all of the Participant’s rights to such Stock Units and the right to receive Common Stock shall terminate without further obligation on the part of the Company unless the Participant remains in the continuous employment of the Company or a Subsidiary (such continuous employment shall, for this purpose, include a period of time during which the Participant is absent from active employment in accordance with a leave of absence policy adopted by the Company or a Subsidiary) for the entire Restriction Period. Notwithstanding the foregoing, the Committee may, if it finds that the circumstances in the particular case so warrant, allow a Participant who ceases to be so continuously employed and has a Separation from Service prior to the Restriction Period Termination Date to retain some or all of the Stock Units. In such event, the Restriction Period and all other restrictions with respect to the retained Stock Units shall lapse, and such Stock Units shall be paid in accordance with Section 5 hereof.

5. PAYMENT OF STOCK UNITS

(i) Subject to Section 25 of the Plan and Sections 4, 5(ii) and 5(iii) hereof, vested Stock Units shall be settled by the delivery to the Participant (through the Participant’s account at the Company’s designated third party stock administrator) or the Participant’s beneficiary or estate, as the case may be, of one share of Common Stock per vested Stock Unit:

(A) except as provided in (B) below, within 30 days of the first to occur of the Restriction Period Termination Date or the Participant’s right to payment arising under Section 4(i), 4(ii), 4(iii), 4(iv) or 4(vii) hereof;

(B) if the Participant’s Stock Units are determined to constitute “deferred compensation” subject to Internal Revenue Code section 409A, such Stock Units shall be paid to the Participant within thirty (30) days of the Restriction Period Termination Date in the event that the Participant’s right to payment:

(1) under Section 4(ii) or Section 4(iv) hereof arises before the Restriction Period Termination Date and after the date the Restriction Period lapses in accordance with Section 4(v) hereof;

(2) arises under Section 4(iii) hereof; or

(3) arises under Section 4(vii) hereof.

4

Notwithstanding the foregoing, (i) the Company shall not be obligated to deliver any shares of Common Stock during any period in which the Company reasonably anticipates that the delivery of shares hereunder would: (A) violate any federal, state or other applicable laws and/or may issue shares subject to any restrictive legend that, as determined by the Company’s counsel, is necessary to comply with securities or other regulatory requirements; or (B) result in the reduction or elimination of the Company’s deduction under Internal Revenue Code section 162(m) with respect to such delivery of shares, and (ii) the date on which shares are delivered to the Participant (and any Dividend Equivalent Payment thereon) may include a delay to provide the Company such time as it determines appropriate to calculate and address tax withholding and to address other administrative matters; provided, however, that delivery of shares of Common Stock underlying Stock Units (and any Dividend Equivalent Payments on such Stock Units, or if such Dividend Equivalent Payments are invested in additional Stock Units at the Company’s discretion, the shares of Common Stock underlying such additional Stock Units) for Stock Units that are determined to be exempt from the requirements of Internal Revenue Code § 409A shall in all events be made at a time that satisfies the “short-term deferral” exception described in Treas. Reg. section 1.409A-1(b)(4) and for Stock Units subject to Internal Revenue Code section 409A shall in all events be made at a time that satisfies Treas. Reg. 1.409A-2(b)(7).

(ii) Notwithstanding the foregoing, the Participant may elect to defer receipt of payment of Common Stock underlying the Stock Units pursuant to the terms of, and in accordance with the provisions of, the Company’s Deferred Compensation Plan. If the Participant elects to defer payment of Common Stock underlying the Stock Units, such payment will be made in accordance with the Company’s Deferred Compensation Plan.

(iii) Notwithstanding the foregoing, if the Participant is an Eligible Employee (within the meaning of the Key Employee Continuity Plan) in the Key Employee Continuity Plan and incurs a Severance within the meaning of the Key Employee Continuity Plan, the payment of Common Stock underlying the Stock Units shall be paid in accordance with Section 2.4 of the Key Employee Continuity Plan, provided the Participant has executed a general release of employment-related claims in the form prescribed by the Key Employee Continuity Plan.

PROTECTION OF CONFIDENTIALITY

By electronically accepting the Award and these Standard Terms and Conditions, the Participant acknowledges and agrees to the following.

6. CONFIDENTIAL INFORMATION; TRADE SECRETS

The Participant acknowledges that the Company regards certain information relating to its business and operations as confidential. This includes all confidential and proprietary information concerning the assets, business or affairs of the Company or any Subsidiary or any customers thereof (“Confidential Information”). The Participant’s electronic signature also acknowledges that the Company has certain information that derives economic value from not being known to the general public or to others who could obtain economic value from its disclosure or use, which the Company takes reasonable efforts to protect the secrecy of (“Trade Secrets”).

7. TYPES OF CONFIDENTIAL INFORMATION OR TRADE SECRETS

The Participant acknowledges that he or she developed or have had and will in the future continue to have access to one or more of the following types of Confidential Information or Trade Secrets: information about rates or costs; customer or supplier agreements and negotiations; business opportunities; scheduling and delivery methods; business and marketing plans; financial information or plans; communications within the attorney-client privilege or other privileges; operating procedures and methods; construction methods and plans; proprietary computer systems design, programming or software; strategic plans; succession plans; proprietary

5

company training programs; employee performance, compensation or benefits; negotiations or strategies relating to collective bargaining agreements and/or labor disputes; and internal or external claims or complaints regarding personal injuries, employment laws or policies, environmental protection, or hazardous materials. By electronically accepting the Grant Notice and these Standard terms and Conditions, the Participant agrees that any unauthorized disclosures by him or her to any third party of such Confidential Information or Trade Secrets would constitute gross misconduct.

8. AGREEMENT TO MAINTAIN CONFIDENTIAL INFORMATION

The Participant agrees that he or she will not, unless he or she receives prior written consent from the senior human resources officer or such other person designated by the Company (hereinafter collectively referred to as the “Sr. HR Officer”), or unless ordered by a court or government agency, (i) divulge, use, furnish or disclose to any subsequent employer or any other person, whether or not a competitor of the Company, any Confidential Information or Trade Secrets, or (ii) retain or take with him or her when he or she leaves the Company any property of the Company or any documents (including any electronic or computer records) relating to any Confidential Information or Trade Secrets.

9. PRIOR NOTICE OF EMPLOYMENT, ETC

(i) The Participant acknowledges that if he or she become an employee, contractor, or consultant for any other person or entity engaged in the Business of the Company as defined in Section 11 (“Entity”), this would create a substantial risk that he or she would, intentionally or unintentionally, disclose or rely upon the Company’s Confidential Information or Trade Secrets for the benefit of the other Entity to the detriment of the Company. The Participant further acknowledges that such disclosures would be particularly damaging if made shortly after he or she leaves the Company. Therefore, by electronically accepting the Grant Notice and these Standard Terms and Conditions, the Participant agrees that for a period of one-year after he or she leaves the Company, before accepting any employment or affiliation with another Entity he or she will give written notice to the Sr. HR Officer of his or her intention to accept such employment or affiliation. The Participant also agrees to confer in good faith with the Sr. HR Officer concerning whether his or her proposed employment or affiliation could reasonably be expected to be performed without improper disclosure of Confidential Information or Trade Secrets.

(ii) If the Sr. HR Officer and the Participant are unable to reach agreement on this issue, he or she agrees to submit this issue to arbitration, to be conducted under the rules of the American Arbitration Association, for final resolution. The Participant also agrees that he or she will not begin to work for another person or entity engaged in the Business of the Company as defined in Section 11, until the Sr. HR Officer or an arbitrator has determined that such employment could reasonably be expected to be performed without improper disclosure of the Company’s Confidential Information or Trade Secrets.

10. FAILURE TO COMPLY

The Participant agrees that, if he or she fails to comply with any of the promises that he or she made in Section 8 or 9 above, he or she will be required to immediately deliver to the Company any shares of Common Stock (or the market value of any shares of Common Stock received) which he or she received at any time from 180 days prior to the earlier of (i) the date when he or she leaves the Company or (ii) the date he or she fails to comply with any such promise made in Section 8 or 9, to 180 days after the date when the Company learns that he or she has not complied with any such promise. The Participant agrees that he or she will deliver such shares of Common Stock (or the cash equivalent) to the Company on such terms and conditions as may be required by the Company. The Participant further agrees that the Company will be entitled to enforce this repayment obligation by all legal means available, including, without limitation, to set off the market value of any such shares of Common Stock against any amount that might be

6

owed to him or her by the Company. The Participant acknowledges that the Company would not have awarded the Participant the shares of Common Stock granted to him or her under the Grant Notice absent the Participant’s agreement to be bound by the promises made in Sections 8 and 9 above.

NO DIRECT COMPETITION

By electronically accepting the Award and these Standard Terms and Conditions, the Participant acknowledges and agrees to the following.

11. NON-SOLICITATION OF CUSTOMERS; NON-COMPETITION

The Participant agrees that for a period of one year following his or her departure from the Company, he or she will not (directly or in association with others) call on or solicit any of the Company’s customers with whom he or she had personal contact while he or she was employed by the Company, for the purpose of providing the customers with goods and/or services similar in nature to those provided by the Company in its Business as defined below. The Participant further agrees that for the same time period, he or she will not, directly or indirectly, engage in any activity which is the same as or competitive with the Business (as defined below) including, without limitation, engagement as an officer, director, proprietor, employee, partner, investor (other than as a holder of less than 2% of the outstanding capital stock of a publicly traded corporation), guarantor, consultant, advisor, agent, sales representative or other participant, in any market in which the Company conducts its Business. For purposes of these Standard Terms and Conditions, the term “Business” means the transportation of goods in interstate commerce and related services in or through or for any state in which the Company or any of its affiliates provides such services directly or indirectly and any other activity that supports such operations including by the way of example but not limitation, marketing, information systems, logistics, technology development or implementation, terminal services and any other activity of the Company or any of its affiliates. This Section 11 is not intended to prevent the Participant from engaging in any activity that is not the same as or competitive with the Business. The Participant acknowledges that the Company would not have awarded him or her the shares of Common Stock granted under the Grant Notice absent his or her agreement to be bound by the promises made in this Section 11.

12. ACKNOWLEDGMENT; INJUNCTIVE RELIEF

The Participant acknowledges that he or she has carefully read and considered all these Standard Terms and Conditions, including the restraints imposed upon him or her pursuant to Sections 8, 9 and 11. The Participant also agrees that each of the restraints contained herein is necessary for the protection of the goodwill, Confidential Information, Trade Secrets and other legitimate interests of the Company; that each and every one of these restraints is reasonable in respect to subject matter, length of time and geographic area; and that these restraints, individually or in the aggregate, will not prevent him or her from obtaining other suitable employment during the period in which he or she are bound by such restraints. The Participant further acknowledges that, were he or she to breach any of the covenants contained in Sections 8, 9 and 11, the damage to the Company would be irreparable. The Participant therefore agrees that the Company, in addition to any other remedies available to it, including, without limitation, the remedies set forth in Sections 10 and 13, shall be entitled to injunctive relief against his or her breach or threaten breach of said covenants. The Participant and the Company further agree that, in the event that any provision of Sections 8, 9 and 11 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, such provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law.

7

13. VIOLATION OF PROMISES

The Participant agrees that if he or she violates any of his or her promises in Section 11, then he or she will be required to immediately deliver to the Company any shares of Common Stock (or the fair market value thereof) granted to him or her by the Grant Notice which he or she received at any time from 180 days prior to the date when he or she leaves the Company to 180 days after the date when the Company learns that he or she has not complied with the promises he or she made in Section 11. The Participant agrees that he or she will deliver such shares of Common Stock (or the fair market value thereof) to the Company on such terms and conditions as may be required by the Company. The Participant further agrees that the Company will be entitled to enforce this repayment obligation by all legal means available, including, without limitation, to set off the market value of any such shares of Common Stock against any amount that might be owed to him or her by the Company.

GENERAL

14. ARBITRATION

The Participant agrees and the Company agrees that any controversy, claim, or dispute arising out of or relating to this Agreement or the breach of any of these terms and conditions, or arising out of or relating to his or her employment relationship with the Company or any of its affiliates, or the termination of such relationship, shall be resolved by binding arbitration before a neutral arbitrator under the rules set forth in the Federal Arbitration Act, except for claims by the Company relating to his or her breach of any of the employee covenants set forth in Paragraphs 6, 7, 8, 9 or 11 above. By way of example only, claims subject to this agreement to arbitrate include claims litigated under federal, state and local statutory or common law, such as the Age Discrimination in Employment Act, Title VII of the Civil Rights Act of 1964, as amended, including the Civil Rights Act of 1994, the Americans with Disabilities Act, the law of contract and the law of tort. The Participant and the Company agree that such claims may be brought in an appropriate administrative forum, but at the point at which the Participant or the Company seek a judicial forum to resolve the matter, this agreement for binding arbitration becomes effective, and the Participant and the Company hereby knowingly and voluntarily waive any right to have any such dispute tried and adjudicated by a judge or jury. The foregoing not to the contrary, the Company may seek to enforce the employee covenants set forth in Paragraphs 6, 7, 8, 9 or 11 above, in any court of competent jurisdiction.

This agreement to arbitrate shall continue in full force and effect despite the expiration or termination of these Standard Terms and Conditions or the Participant’s employment relationship with the Company or any of its affiliates. The Participant and the Company agree that any award rendered by the arbitrator shall be final and binding and that judgment upon the final award may be entered in any court having jurisdiction thereof. The arbitrator may grant any remedy or relief that the arbitrator deems just and equitable, including any remedy or relief that would have been available to the Participant, the Company or any of its affiliates had the mater been heard in court. All expenses of the arbitration, including the required travel and other expenses of the arbitrator and any witnesses, and the costs relating to any proof produced at the direction of the arbitrator, shall be borne equally by the Participant and the Company unless otherwise mutually agreed or unless the arbitrator directs otherwise in the award. The arbitrator’s compensation shall be borne equally by the Participant and the Company unless otherwise mutually agreed or unless the law provides otherwise.

15. SEVERABILITY

If any provision of these Standard Terms and Conditions is, becomes, or is deemed to be invalid, illegal, or unenforceable in any jurisdiction, such provision shall be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of the Company, it

8

shall be stricken and the remainder of these Standard Terms and Conditions shall remain in force and effect.

16. CHOICE OF LAW; JURISDICTION

All questions pertaining to the construction, regulation, validity, and effect of these Standard Terms and Conditions shall be determined in accordance with the laws of the State of Utah, without regard to the conflict of laws doctrine. The Company and the Participant hereby consent and submit to the personal jurisdiction and venue of any state or federal court located in the county of Salt Lake City within the State of Utah for resolution of any and all claims, causes of action or disputes arising out of or related to these Standard Terms and Conditions. Sections 9(ii) and 11 shall not apply to employees who are subject to California law.

17. AMENDMENTS

The Plan and these Standard Terms and Conditions may be amended or altered by the Committee or the Company’s Board of Directors to the extent provided in the Plan.

18. RESTRICTIONS ON RESALES OF SHARES

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any Common Stock issued in respect of vested Stock Units, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other holders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

19. INCOME TAXES

The Company shall not deliver shares in respect of any Stock Units unless and until the Participant has made satisfactory arrangements to satisfy all applicable tax withholding obligations. Unless the Participant pays the tax withholding obligations to the Company by cash or check in connection with the delivery of the Common Stock, withholding may be effected, at the Company’s option, by withholding Common Stock issuable in connection with the vesting of the Stock Units (provided that shares of Common Stock may be withheld only to the extent that such tax withholding will not result in adverse accounting treatment for the Company). The Participant acknowledges that the Company shall have the right to deduct any taxes required to be withheld by law in connection with the delivery of the Stock Units from any amounts payable by it to the Participant (including, without limitation, future cash wages).

20. NON-TRANSFERABILITY OF AWARD

The Participant understands, acknowledges and agrees that, except as otherwise provided in the Plan, the Stock Units may not be sold, assigned, transferred, pledged or otherwise directly or indirectly encumbered or disposed of prior to the payment of the Common Stock to the Participant as provided in Section 5 hereof.

21. LIMITATION OF INTEREST IN SHARES SUBJECT TO STOCK UNITS

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan, the Key Employee Continuity Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common Stock, if any, as shall have been issued to such person upon vesting of the Stock Units. Nothing in the Plan, in the Key Employee Continuity Plan, in the

9

Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue in the Company’s employ or service nor limit in any way the Company’s right to terminate the Participant’s employment at any time for any reason.

22. OTHER AGREEMENTS SUPERSEDED

The Grant Notice, these Standard Terms and Conditions, the Plan and, as applicable, the Key Employee Continuity Plan constitute the entire understanding between the Participant and the Company regarding the Stock Units. Any prior agreements, commitments or negotiations concerning the Stock Units are superseded.

UNION PACIFIC CORPORATION

STANDARD TERMS AND CONDITIONS FOR

NONQUALIFIED STOCK OPTION

These Standard Terms and Conditions apply to the Option granted pursuant to the Union Pacific Corporation 2013 Stock Incentive Plan (the “Plan”), which is identified as nonqualified stock option and is evidenced by a Grant Notice that specifically refers to these Standard Terms and Conditions. In addition to these Terms and Conditions, the Option shall be subject to the terms of the Plan, which are incorporated into these Standard Terms and Conditions by this reference. Capitalized terms not otherwise defined herein shall have the meaning set forth in the Plan.

OPTION

1. TERMS OF OPTION

Union Pacific Corporation (the “Company”), has granted to the Participant named in the Grant Notice provided to said Participant herewith (the “Grant Notice”) a nonqualified stock option (the “Option”) to purchase up to the number of shares of the Company’s common stock (the “Common Stock”), set forth in the Grant Notice. The exercise price per share and the other terms and conditions of the Option are set forth in the Grant Notice, these Standard Terms and Conditions (as amended from time to time), and the Plan. For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

2. NONQUALIFIED STOCK OPTION

The Option is not intended to be an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”) and will be interpreted accordingly.

3. EXERCISE OF OPTION

The Option shall not be exercisable as of the Grant Date set forth in the Grant Notice. After the Grant Date, to the extent not previously exercised, and subject to termination or acceleration as provided in these Standard Terms and Conditions and the Plan, the Option shall be exercisable only to the extent it becomes vested, as described in the Grant Notice, these Standard Terms and Conditions and/or the terms of the Plan, to purchase up to that number of shares of Common Stock as set forth in the Grant Notice, provided that (except as set forth in Section 4A., 4B. and 4C. below) the Participant remains employed with the Company and does not experience a termination of employment.

The exercise price (the “Exercise Price”) of the Option is set forth in the Grant Notice. The Company shall not be obligated to issue any shares of Common Stock until the Participant shall have paid the total Exercise Price for that number of shares of Common Stock. To exercise the Option (or any part thereof), the Participant shall deliver to the Company appropriate notice specifying the number of whole shares of Common Stock the Participant wishes to purchase accompanied by valid payment in the form of (i) a check, (ii) an attestation form confirming the Participant’s current ownership of whole shares of Common Stock equal in value to the total Exercise Price for that number of shares of Common Stock, and/or (iii) an authorization to sell shares equal in value to the total Exercise Price for that number of shares of Common Stock. Notices and authorizations shall be delivered and all checks shall be payable to the Company’s third party stock plan administrator, or as otherwise directed by the Company.

Fractional shares may not be exercised. Shares of Common Stock will be issued as soon as practicable after exercise. Notwithstanding the above, for administrative or other reasons, including, but not limited to the Company’s determination that exercisability of the Option would violate any federal, state or other applicable laws, the Company may from time to time suspend the ability of the Participant to exercise an Option for limited periods of time, which suspensions

shall not change the period in which the Option is exercisable, except as otherwise provided in the Plan.

4. EXPIRATION OF OPTION

Except as otherwise may be provided by the Committee consistent with the terms of the Plan, the Option shall expire and cease to be exercisable as of the earlier of (a) the Expiration Date set forth in the Grant Notice or (b) the date specified below in Sections 4A. through 4G., as applicable.

A. If the Participant’s termination of employment is by reason of death or the Participant is determined to be disabled under the provisions of the Company’s or a Subsidiary’s long-term disability plan, then any vesting period with respect to the Option shall be deemed to be satisfied and the Option shall become fully vested and exercisable (by the Participant or the Participant’s estate, beneficiary or legal representative, as the case may be) at the date of such termination of employment or the first day on which the Participant is determined to be disabled under such long-term disability plan, as the case may be, until the date that is five (5) years following the date of such termination of employment or the first day of disability as determined under such long-term disability plan, as the case may be.

B. If the Participant remains continuously employed with the Company or a Subsidiary until September 30, 2015, (which shall include a period of time during which the Participant is absent from active employment in accordance with a leave of absence policy adopted by the Company or a Subsidiary), and retires at or after attaining age 62 with 10 years of service under the provisions of the Company’s or a Subsidiary’s pension plan (“62/10 Status”), then the Option shall be exercisable in accordance with and at the times it becomes vested, as described in the Grant Notice, notwithstanding the Participant’s termination of employment with the Company or a Subsidiary, until the date that is five (5) years following the date of such termination of employment.

C. If the Participant’s employment is involuntarily terminated by the Company or any of its Subsidiaries (other than a termination as a result of disability, cause or gross misconduct) within two (2) years following a Change in Control (as defined in the Plan), any vesting period with respect to the Option shall be deemed to be satisfied and the Participant may exercise the Option upon the date of such termination of employment, and the Option shall remain exercisable until the date that is three (3) years following the date of such termination of employment (or until the date that is five (5) years following the date of such termination of employment, in the case of a termination of employment by reason of the Participant’s death or a termination of employment described in Section 4B. or Section 4D. hereof). Furthermore, the Option exercise period shall be as described in Section 4A. in the event the Participant is determined to be disabled under the provisions of the Company’s or a Subsidiary’s long-term disability plan prior to the Participant’s termination of employment described in this Section 4C.

D. If the Participant terminates employment and at the time of such termination of employment the Participant is eligible (age 65 or at least age 55 with 10 years of vesting service) to begin receiving pension payments immediately (whether or not such Participant actually begins to receive payments) from a qualified pension plan sponsored by the Company or a Subsidiary, the Participant may exercise any portion of the Option that is vested and exercisable at the time of the Participant’s termination of employment until the date that is five (5) years following the date of such termination of employment.

E. In the event of a Change in Control in which the acquiring or surviving company in the transaction does not assume or continue the Option upon the Change in Control, any vesting period with respect to the Option shall be deemed to be satisfied and the Option

2

shall become fully vested and exercisable (provided that the Option may be canceled upon the consummation of the Change in Control without payment of any additional consideration if the exercise price of the Option is less than the consideration per Share payable to shareholders of the Company in such Change in Control) and the Participant may exercise the Option not assumed or continued until the date that is five (5) years following the date of such Change in Control. If the Participant terminates employment following such Change in Control for a reason described in 4F., any unexercised portion of the Option shall be immediately forfeited and canceled as of the date of such termination of employment.

F. Notwithstanding any other provision of this Section 4, if the Participant’s employment is terminated by the Company for deliberate, willful or gross misconduct, the unexercised portion of the Option, whether or not then vested and exercisable, shall be immediately forfeited and canceled as of the date of such termination of employment.

G. Except as otherwise provided in this Section 4 hereof, the Participant may exercise any portion of the Option that is vested and exercisable at the time of the Participant’s termination of employment until the date that is three (3) months following the date of such termination of employment. Any portion of the Option that is not vested and exercisable at the time of such termination of employment shall be forfeited and canceled as of the date of such termination of employment.

PROTECTION OF CONFIDENTIALITY

By electronically accepting the Option and these Standard Terms and Conditions, the Participant acknowledges and agrees to the following.

5. CONFIDENTIAL INFORMATION; TRADE SECRETS

The Participant acknowledges that the Company regards certain information relating to its business and operations as confidential. This includes all confidential and proprietary information concerning the assets, business or affairs of the Company or any Subsidiary or any customers thereof (“Confidential Information”). The Participant’s electronic signature also acknowledges that the Company has certain information that derives economic value from not being known to the general public or to others who could obtain economic value from its disclosure or use, which the Company takes reasonable efforts to protect the secrecy of (“Trade Secrets”).

6. TYPES OF CONFIDENTIAL INFORMATION OR TRADE SECRETS

The Participant acknowledges that he or she developed or have had and will in the future continue to have access to one or more of the following types of Confidential Information or Trade Secrets: information about rates or costs; customer or supplier agreements and negotiations; business opportunities; scheduling and delivery methods; business and marketing plans; financial information or plans; communications within the attorney-client privilege or other privileges; operating procedures and methods; construction methods and plans; proprietary computer systems design, programming or software; strategic plans; succession plans; proprietary company training programs; employee performance, compensation or benefits; negotiations or strategies relating to collective bargaining agreements and/or labor disputes; and internal or external claims or complaints regarding personal injuries, employment laws or policies, environmental protection, or hazardous materials. By electronically accepting the Grant Notice and these Standard terms and Conditions, the Participant agrees that any unauthorized disclosures by him or her to any third party of such Confidential Information or Trade Secrets would constitute gross misconduct.

3

7. AGREEMENT TO MAINTAIN CONFIDENTIAL INFORMATION

The Participant agrees that he or she will not, unless he or she receives prior written consent from the senior human resources officer or such other person designated by the Company (hereinafter collectively referred to as the “Sr. HR Officer”), or unless ordered by a court or government agency, (i) divulge, use, furnish or disclose to any subsequent employer or any other person, whether or not a competitor of the Company, any Confidential Information or Trade Secrets, or (ii) retain or take with him or her when he or she leaves the Company any property of the Company or any documents (including any electronic or computer records) relating to any Confidential Information or Trade Secrets.

8. PRIOR NOTICE OF EMPLOYMENT, ETC

(i) The Participant acknowledges that if he or she become an employee, contractor, or consultant for any other person or entity engaged in the Business of the Company as defined in Section 10 (“Entity”), this would create a substantial risk that he or she would, intentionally or unintentionally, disclose or rely upon the Company’s Confidential Information or Trade Secrets for the benefit of the other Entity to the detriment of the Company. The Participant further acknowledges that such disclosures would be particularly damaging if made shortly after he or she leaves the Company. Therefore, by electronically accepting the Grant Notice and these Standard Terms and Conditions, the Participant agrees that for a period of one-year after he or she leaves the Company, before accepting any employment or affiliation with another Entity he or she will give written notice to the Sr. HR Officer of his or her intention to accept such employment or affiliation. The Participant also agrees to confer in good faith with the Sr. HR Officer concerning whether his or her proposed employment or affiliation could reasonably be expected to be performed without improper disclosure of Confidential Information or Trade Secrets.

(ii) If the Sr. HR Officer and the Participant are unable to reach agreement on this issue, he or she agrees to submit this issue to arbitration, to be conducted under the rules of the American Arbitration Association, for final resolution. The Participant also agrees that he or she will not begin to work for another person or entity engaged in the Business of the Company as defined in Section 10, until the Sr. HR Officer or an arbitrator has determined that such employment could reasonably be expected to be performed without improper disclosure of the Company’s Confidential Information or Trade Secrets.

9. FAILURE TO COMPLY

The Participant agrees that, if he or she fails to comply with any of the promises that he or she made in Section 7 or 8 above, (a) the Option, to the extent then unexercised, whether vested or unvested, will be immediately forfeited and cancelled and (b) the Participant will be required to immediately deliver to the Company an amount (in cash or in shares of Common Stock) equal to the market value (on the date of exercise) of any shares of Common Stock acquired on exercise of the Option less the exercise price paid for such shares to the extent such shares were acquired by the Participant upon exercise of the Option at any time from 180 days prior to the earlier of (i) the date when he or she leaves the Company or (ii) the date he or she fails to comply with any such promise that hr or she made in Section 7 or 8, to 180 days after the date when the Company learns that the Participant has not complied with any such promise. The Participant agrees that he or she will deliver such shares of Common Stock (or the cash equivalent) to the Company on such terms and conditions as may be required by the Company. The Participant further agrees that the Company will be entitled to enforce this repayment obligation by all legal means available, including, without limitation, to set off the market value of any such shares of Common Stock against any amount that might be owed to him or her by the Company. The Participant acknowledges that the Company would not have awarded the Participant the shares of Common Stock granted to him or her under the Grant Notice absent the Participant’s agreement to be bound by the promises made in Sections 7 and 8 above.

4

NO DIRECT COMPETITION

By electronically accepting the Option and these Standard Terms and Conditions, the Participant acknowledges and agrees to the following.

10. NON-SOLICITATION OF CUSTOMERS; NON-COMPETITION

The Participant agrees that for a period of one year following his or her departure from the Company, he or she will not (directly or in association with others) call on or solicit any of the Company’s customers with whom he or she had personal contact while he or she was employed by the Company, for the purpose of providing the customers with goods and/or services similar in nature to those provided by the Company in its Business as defined below. The Participant further agrees that for the same time period, he or she will not, directly or indirectly, engage in any activity which is the same as or competitive with the Business (as defined below) including, without limitation, engagement as an officer, director, proprietor, employee, partner, investor (other than as a holder of less than 2% of the outstanding capital stock of a publicly traded corporation), guarantor, consultant, advisor, agent, sales representative or other participant, in any market in which the Company conducts its Business. For purposes of these Standard Terms and Conditions, the term “Business” means the transportation of goods in interstate commerce and related services in or through or for any state in which the Company or any of its affiliates provides such services directly or indirectly and any other activity that supports such operations including by the way of example but not limitation, marketing, information systems, logistics, technology development or implementation, terminal services and any other activity of the Company or any of its affiliates. This Section 10 is not intended to prevent the Participant from engaging in any activity that is not the same as or competitive with the Business. The Participant acknowledges that the Company would not have awarded him or her the shares of Common Stock granted under the Grant Notice absent his or her agreement to be bound by the promises made in this Section 10.

11. ACKNOWLEDGMENT; INJUNCTIVE RELIEF

The Participant acknowledges that he or she has carefully read and considered all these Standard Terms and Conditions, including the restraints imposed upon him or her pursuant to Sections 7, 8 and 10. The Participant also agrees that each of the restraints contained herein is necessary for the protection of the goodwill, Confidential Information, Trade Secrets and other legitimate interests of the Company; that each and every one of these restraints is reasonable in respect to subject matter, length of time and geographic area; and that these restraints, individually or in the aggregate, will not prevent him or her from obtaining other suitable employment during the period in which he or she are bound by such restraints. The Participant further acknowledges that, were he or she to breach any of the covenants contained in Sections 7, 8 and 10, the damage to the Company would be irreparable. The Participant therefore agrees that the Company, in addition to any other remedies available to it, including, without limitation, the remedies set forth in Sections 9 and 12, shall be entitled to injunctive relief against his or her breach or threaten breach of said covenants. The Participant and the Company further agree that, in the event that any provision of Sections 7, 8 and 10 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, such provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law.

12. VIOLATION OF PROMISES

The Participant agrees that if he or she violates any of his or her promises in Section 10 above, (a) the Option, to the extent then unexercised, whether vested or unvested, will be immediately forfeited and cancelled and (b) the Participant will be required to immediately deliver to the Company an amount (in cash or in shares of Common Stock) equal to the market value (on the

5

date of exercise) of any shares of Common Stock acquired on exercise of the Option less the exercise price paid for such shares to the extent such shares were acquired by him or her upon exercise of the Option at any time from 180 days prior to the date when he or she leaves the Company to 180 days after the date when the Company learns that he or she has not complied with any such promise. The Participant agrees that he or she will deliver such shares of Common Stock (or the fair market value thereof) to the Company on such terms and conditions as may be required by the Company. The Participant further agrees that the Company will be entitled to enforce this repayment obligation by all legal means available, including, without limitation, to set off the market value of any such shares of Common Stock against any amount that might be owed to him or her by the Company.

GENERAL

13. ARBITRATION

The Participant agrees and the Company agrees that any controversy, claim, or dispute arising out of or relating to this Agreement or the breach of any of these terms and conditions, or arising out of or relating to his or her employment relationship with the Company or any of its affiliates, or the termination of such relationship, shall be resolved by binding arbitration before a neutral arbitrator under the rules set forth in the Federal Arbitration Act, except for claims by the Company relating to his or her breach of any of the employee covenants set forth in Paragraphs 5, 6, 7, 8 or 10 above. By way of example only, claims subject to this agreement to arbitrate include claims litigated under federal, state and local statutory or common law, such as the Age Discrimination in Employment Act, Title VII of the Civil Rights Act of 1964, as amended, including the Civil Rights Act of 1994, the Americans with Disabilities Act, the law of contract and the law of tort. The Participant and the Company agree that such claims may be brought in an appropriate administrative forum, but at the point at which the Participant or the Company seek a judicial forum to resolve the matter, this agreement for binding arbitration becomes effective, and the Participant and the Company hereby knowingly and voluntarily waive any right to have any such dispute tried and adjudicated by a judge or jury. The foregoing not to the contrary, the Company may seek to enforce the employee covenants set forth in Paragraphs 5, 6, 7, 8 or 10 above, in any court of competent jurisdiction.

This agreement to arbitrate shall continue in full force and effect despite the expiration or termination of these Standard Terms and Conditions or the Participant’s employment relationship with the Company or any of its affiliates. The Participant and the Company agree that any award rendered by the arbitrator shall be final and binding and that judgment upon the final award may be entered in any court having jurisdiction thereof. The arbitrator may grant any remedy or relief that the arbitrator deems just and equitable, including any remedy or relief that would have been available to the Participant, the Company or any of its affiliates had the mater been heard in court. All expenses of the arbitration, including the required travel and other expenses of the arbitrator and any witnesses, and the costs relating to any proof produced at the direction of the arbitrator, shall be borne equally by the Participant and the Company unless otherwise mutually agreed or unless the arbitrator directs otherwise in the award. The arbitrator’s compensation shall be borne equally by the Participant and the Company unless otherwise mutually agreed or unless the law provides otherwise.

14. SEVERABILITY

If any provision of these Standard Terms and Conditions is, becomes, or is deemed to be invalid, illegal, or unenforceable in any jurisdiction, such provision shall be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of the Company, it shall be stricken and the remainder of these Standard Terms and Conditions shall remain in force and effect.

6

15. CHOICE OF LAW; JURISDICTION

All questions pertaining to the construction, regulation, validity, and effect of these Standard Terms and Conditions shall be determined in accordance with the laws of the State of Utah, without regard to the conflict of laws doctrine. The Company and the Participant hereby consent and submit to the personal jurisdiction and venue of any state or federal court located in the county of Salt Lake City within the State of Utah for resolution of any and all claims, causes of action or disputes arising out of or related to these Standard Terms and Conditions. Sections 8(ii) and 10 shall not apply to employees who are subject to California law.

16. AMENDMENTS

The Plan and these Standard Terms and Conditions may be amended or altered by the Committee or the Company’s Board of Directors to the extent provided in the Plan.

17. RESTRICTIONS ON RESALES OF SHARES ACQUIRED PURSUANT TO OPTION EXERCISE

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any Common Stock issued as a result of the exercise of the Option, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other optionholders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

18. INCOME TAXES

The Company shall not deliver shares of Common Stock in respect of the exercise of any Option unless and until the Participant has made satisfactory arrangements to satisfy all applicable tax withholding obligations. Unless the Participant pays the tax withholding obligations to the Company by cash or check in connection with the exercise of the Option, tax withholding may be effected, at the Company’s option, by withholding Common Stock issuable in connection with the exercise of the Option (provided that shares of Common Stock may be withheld only to the extent that such tax withholding will not result in adverse accounting treatment for the Company). The Participant acknowledges that the Company shall have the right to deduct any taxes required to be withheld by law in connection with the exercise of the Option from any amounts payable by it to the Participant (including, without limitation, future cash wages).

19. NON-TRANSFERABILITY OF OPTION

Except as permitted under the Plan, the Participant may not assign or transfer the Option to anyone other than by will or the laws of descent and distribution and the Option shall be exercisable only by the Participant during his or her lifetime or, following a Participant’s death, by the Participant’s beneficiary. The Company may cancel the Participant’s Option if the Participant attempts to assign or transfer it in a manner inconsistent with this Section 19.

20. LIMITATION OF INTEREST IN SHARES SUBJECT TO OPTION

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common Stock, if any, as shall have been issued to such person upon exercise of the Option or any part of it. Nothing in the Plan, in the Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue in

7

the Company’s employ or service nor limit in any way the Company’s right to terminate the Participant’s employment at any time for any reason.

21. OTHER AGREEMENTS SUPERSEDED

The Grant Notice, these Standard Terms and Conditions and the Plan constitute the entire understanding between the Participant and the Company regarding the Option. Any prior agreements, commitments or negotiations concerning the Option are superseded.

Variable Interest Entities [Abstract]

Variable Interest Entities [Text Block]

16. Variable Interest Entities

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

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

We are not considered to be the primary beneficiary and do not consolidate these VIEs because our actions and decisions do not have the most significant effect on the VIE's performance and our fixed-price purchase options are not considered to be potentially significant to the VIEs. The future minimum lease payments associated with the VIE leases totaled $3.0 billion as ofDecember 31, 2014.

Share Repurchase Program [Text Block]

19.       Share Repurchase Program

Effective January 1, 2014, our Board of Directors authorized the repurchase of up to 120 million shares of our common stock by December 31, 2017, replacing our previous repurchase program. As of December 31, 2014, we repurchased a total of $12.6 billion of our common stock since the commencement of our repurchase programs in 2007. The table below represents shares repurchased in 2013 under our previous repurchase program, and shares repurchased in 2014 under the new program.

	Number of Shares Purchased		Average Price Paid
	2014	2013		2014		2013
First quarter	7,640,000	5,762,800	$	89.43	$	68.29
Second quarter	8,320,000	6,122,940		96.84		75.71
Third quarter	8,347,000	7,333,788		102.54		78.39
Fourth quarter	7,736,400	9,858,110		113.77		79.68
Total	32,043,400	29,077,638	$	100.65	$	76.26
Remaining number of shares that may be repurchased under current authority						87,956,600

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

From January 1, 2015, through February 6, 2015, we repurchased 2.8 million shares at an aggregate cost of approximately $327 million.

Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Significant Accounting Policies [Abstract]

Principles of Consolidation Policy [Text Block]

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 Policy [Text Block]

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

Accounts Receivables Policy [Text Block]

Accounts Receivable –Accounts receivable includes receivables reduced by an allowance for doubtful accounts. The allowanceis based upon historical losses, credit worthiness of customers, and current economic conditions. Receivables not expected to be collected in one year and the associated allowancesare classified as other assets in our Consolidated Statements of Financial Position.

Investments Policy [Text Block]

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 Policy [Text Block]

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

Property and Depreciation Policy [Text Block]

Property and Depreciation – 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), for which lives 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 lives 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 determine the estimated service lives of depreciable railroad assets by means of depreciation studies. Under the group method of depreciation, no gain or loss is recognized when depreciable property is retired or replaced in the ordinary course of business.

Impairment of Long-lived Assets Policy [Text Block]

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 Policy [Text Block]

Revenue Recognition – We recognize freight revenues 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, which include revenues earned by our subsidiaries, revenues from our commuter rail operations, and accessorial revenue, 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 Policy [Text Block]

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.

Fair Value Measurements Policy [Text Block]

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 and short- and long-term debt.

Stock-Based Compensation Policy [Text Block]

Stock-Based Compensation –We have several stock-based compensation plans under which employees and non-employee directors receive stock options, nonvested retention shares, and nonvested stock units. We refer to the nonvested shares and stock units collectively as “retention awards”. We have elected to issue treasury shares to cover option exercises and stock unit vestings, while new shares are issued when retention shares are granted.

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.

Earnings Per Share Policy [Text Block]

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.

Income Taxes Policy [Text Block]

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 tax legislation are not anticipated. Future tax legislation, 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 for purposes of estimating whether future taxable income will be sufficient to realize a deferred tax asset.

We recognize tax benefits 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 Policy [Text Block]

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, compensation 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 an actuarial analysis to measure the expense and liability associated with these benefits.

Personal Injury Policy [Text Block]

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 an actuarial analysis to measure the expense and liability. Our personal injury liability is not discounted to present value. Legal fees and incidental costs are expensed as incurred.

Asbestos Policy [Text Block]

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 a statistical analysis 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 Policy [Text Block]

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 perform, with the assistance of our consultants, 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.

Use Of Estimates Policy [Text Block]

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.

Total debt	$	11,480

Equipment Encumbrances – Equipment with a carrying value of approximately $2.8 billion and $2.9 billion atDecember 31, 2014,and 2013, respectively,served as collateral for capital leases and other types of equipment obligations in accordance with the secured financing arrangements utilized to acquire such railroad equipment.

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 –During the second quarter of 2014, we replaced our $1.8 billion revolving credit facility, which was scheduled to expire in May 2015, with a new $1.7 billion facility that expires in May 2019 (the facility). The facility is based on substantially similar terms as those in the previous credit facility. On December 31, 2014, we had $1.7 billion of credit available under the facility, which is designated for general corporate purposes and supports the issuance of commercial paper. We did not draw on either facility at any time during 2014. 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 credit ratings for our senior unsecured debt.

The facility requires that the Corporation maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing. At December 31, 2014, and December 31, 2013 (and at all times during the year), 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, 2014, the debt-to-net-worth coverage ratio allowed us to carry up to $42.4 billion of debt (as defined in the facility), and we had $11.6billion of debt (as defined in the facility) outstanding at that date. Under our current capital plans, we expect to continue to satisfy the debt-to-net-worth coverage ratio; however, many factors beyond our reasonable control could affect our ability to comply with this provision in the future. The facility does not include any other financial restrictions, credit rating triggers (other than rating-dependent pricing), or any other provision that could require us to post collateral. The facility also includes a $125 million cross-default provision and a change-of-control provision.

During 2014, we did not issue or repay any commercial paper, and at December 31, 2014, and 2013, we had no commercial paper outstanding. Our revolving credit facility supports our outstanding commercial paper balances, and, unless we change the terms of our commercial paper program, our aggregate issuance of commercial paper will not exceed the amount of borrowings available under the facility.

Dividend Restrictions – Our revolving credit facility includes a debt-to-net worth covenant (discussed in the Credit Facilities section above) that, under certain circumstances, restricts the payment of cash dividends to our shareholders. The amount of retained earnings available for dividends was $15.4 billion and $16.3 billion at December 31, 2014,and 2013, respectively.

Shelf Registration Statement and Significant New Borrowings – Under our current shelf registration, we may issue, from time to time, any combination of debt securities, preferred stock, common stock, or warrants for debt securities or preferred stock in one or more offerings. We have no immediate plans to issue equity securities; however, we will continue to explore opportunities to replace existing debt or access capital through issuances of debt securities under our shelf registration, and, therefore, we may issue additional debt securities at any time.

During 2014, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
January 10, 2014	$300 million of 2.25% Notes due February 15, 2019
	$400 million of 3.75% Notes due March 15, 2024
	$300 million of 4.85% Notes due June 15, 2044
August 12, 2014	$350 million of 3.25% Notes due January 15, 2025
	$350 million of 4.15% Notes due January 15, 2045

We used the net proceeds from the offerings for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities include change-of-control provisions.At December 31, 2014, we had remaining authority to issue up to $1.15 billion of debt securities under our shelf registration.

Subsequent Event - In 2015, we issued the following unsecured, fixed-rate debt securities under our current shelf registration:

Date	Description of Securities
January 29, 2015	$250 million of 1.80% Notes due February 1, 2020
	$450 million of 3.375% Notes due February 1, 2035
	$450 million of 3.875% Notes due February 1, 2055

Proceeds from this offering are for general corporate purposes, including the repurchase of common stock pursuant to our share repurchase program. These debt securities include change-of-control provisions.This offering exhausted our current authority to issue debt securities under our existing shelf registration.

On February 5, 2015, the Board of Directors approved proceeding with a new shelf registration statement and authorized the issuance of up to $4.0 billion of debt securities.

Equipment Trust– On May 20, 2014, UPRR consummated a pass-through (P/T) financing, whereby a P/T trust was created, which issued $500 million of P/T trust certificates with a stated interest rate of 3.227%. The P/T trust certificates will mature on May 14, 2026. The proceeds from the issuance of the P/T trust certificates (net of $3 million in transaction fees) were used to purchase equipment trust certificates to be issued by UPRR to finance the acquisition of 245 locomotives. The equipment trust certificates are secured by a lien on the locomotives.

Debt Exchange– On August 21, 2013, we exchanged $1,170 million of various outstanding notes and debentures due between 2016 and 2040 (the Existing Notes) for $439 million of 3.646% notes (the New 2024 Notes) due February 15, 2024 and $700 million of 4.821% notes (the New 2044 Notes) due February 1, 2044, plus cash consideration of approximately $280 million in addition to $8 million for accrued and unpaid interest on the Existing Notes. In accordance with ASC 470-50-40, Debt-Modifications and Extinguishments-Derecognition, this transaction was accounted for as a debt exchange, as the exchanged debt instruments are not considered to be substantially different. The cash consideration was recorded as an adjustment to the carrying value of debt, and the balance of the unamortized discount and issue costs from the Existing Notes is being amortized as an adjustment of interest expense over the terms of the New 2024 Notes and the New 2044 Notes. No gain or loss was recognized as a result of the exchange. Costs related to the debt exchange that were payable to parties other than the debt holders totaled approximately $9 million and were included in interest expense during the three months ended September 30, 2013.

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

Components of income tax expense were as follows for the years ended December 31:

Millions	2014		2013		2012
Current tax expense:
Federal	$	2,029	$	1,738	$	1,335
State		239		199		153
Total current tax expense		2,268		1,937		1,488
Deferred tax expense:

State		6		(1)		2
Total unrecognized tax benefits expense/(benefits)		92		(55)		7
Total income tax expense	$	3,163	$	2,660	$	2,375

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

Tax Rate Percentages	2014		2013		2012
Federal statutory tax rate	35.0	%	35.0	%	35.0	%
State statutory rates, net of federal benefits	3.1		3.1		3.1
Deferred tax adjustments	-		(0.1)		(0.1)

Other	0.2		(0.1)		0.1
Effective tax rate	37.9	%	37.7	%	37.6	%

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 assets relate to deductions that already have been claimed for financial reporting purposes but not for 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 (including bonus 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	2014		2013
Deferred income tax liabilities:
Property	$	(15,173)	$	(14,448)
Other		(411)		(260)
Total deferred income tax liabilities		(15,584)		(14,708)
Deferred income tax assets:
Accrued wages		74		71
Accrued casualty costs		228		223
Accrued stock compensation		69		66
Debt and leases		86		41
Retiree benefits		392		100
Credits		164		182
Other		168		130
Total deferred income tax assets	$	1,181	$	813
Net deferred income tax liability	$	(14,403)	$	(13,895)
Current portion of deferred taxes	$	277	$	268
Non-current portion of deferred taxes		(14,680)		(14,163)
Net deferred income tax liability	$	(14,403)	$	(13,895)

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 for purposes of estimating whether future taxable income will be sufficient to realize a deferred tax asset. In 2014 and 2013, there were no valuation allowances.

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.

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

Millions	2014		2013		2012
Unrecognized tax benefits at January 1	$	59	$	115	$	107
Increases for positions taken in current year		92		24		29
Increases for positions taken in prior years		21		15		4
Decreases for positions taken in prior years		(14)		(30)		(19)
Payments to and settlements with taxing authorities		(7)		(63)		-
Increases/(decreases) for interest and penalties		1		-		(4)
Lapse of statutes of limitations		(1)		(2)		(2)
Unrecognized tax benefits at December 31	$	151	$	59	$	115

We recognize interest and penalties as part of income tax expense. Total accrued liabilities for interest and penalties were $6 million at both December 31, 2014 and 2013. Total interest and penalties recognized as part of income tax expense (benefit) were $9 million for 2014, $7 million for 2013, and $(4) million for 2012.

Internal Revenue Service (IRS) examinations have been completed and settled for all years prior to 2009, and the statute of limitations bars any additional tax assessments. The IRS has completed their examinations and issued notices of deficiency for tax years 2009 through 2010. We disagree with many of their proposed adjustments, and we are at IRS Appeals for those years. Additionally, several state tax authorities are examining our state income tax returns for years 2006 through 2010.

In the fourth quarter of 2014, UPC and the IRS signed a closing agreement resolving all tax matters for tax years 2005-2008. The settlement had an immaterial effect on our income tax expense. In connection with the settlement, UPC paid $11 million in 2014.

In 2012, UPC and the IRS signed a closing agreement resolving all tax matters for tax years 1999-2004. The settlement had an immaterial effect on our income tax expense. In connection with the settlement, we received refunds of $8 million in 2013.

We do not expect our unrecognized tax benefits to change significantly in the next 12 months. At December 31, 2014, we had a net unrecognized tax benefit liability of $151 million. Of that amount, $6 million is classified as a current liability in the Consolidated Statement of Financial Position.

The portion of our unrecognized tax benefits that relates to permanent changes in tax and interest would reduce our effective tax rate, if recognized. The remaining unrecognized tax benefits relate to tax positions for which only the timing of the benefit is uncertain. Recognition of the tax benefits with uncertain timing 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	2014		2013		2012
Unrecognized tax benefits that would reduce the effective tax rate	$	33	$	34	$	41
Unrecognized tax benefits that would not reduce the effective tax rate		118		25		74
Total unrecognized tax benefits	$	151	$	59	$	115

Common stock options totaling 0.4 million, 0.5 million, and 1.1 million for 2014, 2013, and 2012, 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.

3. Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the revenue recognition guidance in Topic 605, Revenue Recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in the exchange for those goods or services. This standard is effective for annual reporting periods beginning after December 15, 2016. ASU 2014-09 is not expected to have a material impact on our consolidated financial position, results of operations, or cash flows.

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.

Accounts Receivable –Accounts receivable includes receivables reduced by an allowance for doubtful accounts. The allowanceis based upon historical losses, credit worthiness of customers, and current economic conditions. Receivables not expected to be collected in one year and the associated allowancesare classified as other assets in our Consolidated Statements of Financial Position.

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 – 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), for which lives 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 lives 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 determine the estimated service lives of depreciable railroad assets by means of depreciation studies. Under the group method of depreciation, no gain or loss is recognized when depreciable property is retired or replaced in the ordinary course of business.

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 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, which include revenues earned by our subsidiaries, revenues from our commuter rail operations, and accessorial revenue, 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.

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 and short- and long-term debt.

Stock-Based Compensation –We have several stock-based compensation plans under which employees and non-employee directors receive stock options, nonvested retention shares, and nonvested stock units. We refer to the nonvested shares and stock units collectively as “retention awards”. We have elected to issue treasury shares to cover option exercises and stock unit vestings, while new shares are issued when retention shares are granted.

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.

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.

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 tax legislation are not anticipated. Future tax legislation, 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 for purposes of estimating whether future taxable income will be sufficient to realize a deferred tax asset.

We recognize tax benefits 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, compensation 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 an actuarial analysis to measure 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 an actuarial analysis to measure the expense and liability. Our personal injury liability is not discounted to present value. 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 a statistical analysis 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 perform, with the assistance of our consultants, 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.

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.

14.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.

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, 2014, and 2013, we were not required to provide collateral, nor had we received collateral, relating to our hedging activities.

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. As of December 31, 2014, and 2013, we had no interest rate fair value hedges outstanding.

Interest Rate Cash Flow Hedges – We report changes in the fair value of cash flow hedges in accumulated other comprehensive loss until the hedged item affects earnings. AtDecember 31, 2014, and 2013, we had reductions of $0 and $1 million, respectively,recorded as an accumulated other comprehensive loss. As of December 31, 2014, and 2013, we had no interest rate cash flow hedges outstanding.

Earnings Impact – Our use of derivative financial instruments had no impact on pre-tax income for the years ended December 31, 2014, 2013, and 2012.

Fair Value of FinancialInstruments – The fair value of our short- and long-term debt was estimated using a market value price model, which utilizes applicable U.S. Treasury rates along with current market quotes on comparable debt securities. All of the inputs used to determine the fair market value of the Corporation's long-term debt are Level 2 inputs and obtained from an independent source. At December 31, 2014, the fair value of total debt was $13.0billion, approximately $1.5billion more than the carrying value. At December 31, 2013, the fair value of total debt was $10.2 billion, approximately $0.6 billion more than the carrying value. The fair value of the Corporation's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules. At both December 31, 2014, and 2013, approximately$163 million of debt securities contained call provisions that allow us to retire the debt instruments prior to final maturity, with the payment of fixed call premiums, or in certain cases, at par. The fair value of our cash equivalents approximates their carrying value due to the short-term maturities of these instruments.

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 medical and life insurance benefits for eligible retirees. These benefits are funded as medical claims and life insurance premiums are paid.

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 projected benefit obligation(PBO) and the fair value of the plan assets. Our non-qualified (supplemental) pension plan is unfunded by design. The PBO of the pension plans is the present value of benefits earned to date by plan participants, including the effect of assumed future compensation 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 compensation 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 were as follows for the years ended December 31:

Funded Status	Pension				OPEB
Millions	2014		2013		2014		2013
Projected Benefit Obligation
Projected benefit obligation at beginning of year	$	3,372	$	3,591	$	330	$	372

Amounts recognized in the statement of financial position as of December 31, 2014 and 2013 consist of:

	Pension				OPEB
Millions	2014		2013		2014		2013

Net amounts recognized at end of year	$	(488)	$	57	$	(354)	$	(330)

The change in the funded status and accumulated other comprehensive income/(loss) is primarily a result of implementing a new set of mortality tables issued by the Society of Actuaries in October 2014 and lower discount rates.

Pre-tax amounts recognized in accumulated other comprehensive income/(loss) as of December 31, 2014 and 2013 consist of:

	2014							2013
Millions	Pension		OPEB		Total		Pension		OPEB		Total
Prior service (cost)/credit	$	-	$	17	$	17	$	-	$	28	$	28

Total	$	(1,727)	$	(131)	$	(1,858)	$	(1,018)	$	(97)	$	(1,115)

Pre-tax changes recognized in other comprehensive income/(loss) during 2014, 2013 and 2012 were as follows:

	Pension							OPEB

Net actuarial loss		(103)		(13)		(116)
Total	$	(103)	$	(3)	$	(106)

Underfunded Accumulated Benefit Obligation – The accumulated benefit obligation (ABO) is the present value of benefits earned to date, assuming no future compensation growth. The underfunded accumulated benefit obligation represents the difference between the ABO and the fair value of plan assets. At December 31, 2014 and2013, the non-qualified (supplemental) plan ABO was $379 million and $302 million, respectively.The following table discloses only the PBO, ABO, and fair value of plan assets for pension plans where the accumulated benefit obligation is in excess of the fair value of the plan assets as ofDecember 31:

Underfunded Accumulated Benefit Obligation
Millions	2014		2013
Projected benefit obligation	$	388	$	308
Accumulated benefit obligation	$	379	$	302
Fair value of plan assets		-		-
Underfunded accumulated benefit obligation	$	(379)	$	(302)

The ABO for all defined benefit pension plans was $3.9 billion and $3.2billion at December 31, 2014 and 2013, respectively.

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

	Pension		OPEB
Percentages	2014	2013	2014	2013
Discount rate	3.94%	4.72%	3.74%	4.47%
Compensation increase	4.00%	4.00%	N/A	N/A
Health care cost trend rate (employees under 65)	N/A	N/A	6.34%	6.49%
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 in accumulated other comprehensive income and, if necessary, amortized as pension or OPEB expense.

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

	Pension							OPEB
Millions	2014		2013		2012		2014		2013		2012
Net Periodic Benefit Cost:
Service cost	$	70	$	72	$	54	$	2	$	3	$	3
Interest cost		158		134		141		14		12		15
Expected return on plan assets		(230)		(202)		(190)		-		-		-
Amortization of:
Prior service cost/(credit)		-		-		1		(11)		(16)		(18)
Actuarial loss		71		106		83		10		15		13
Net periodic benefit cost/(benefit)	$	69	$	110	$	89	$	15	$	14	$	13

Assumptions – The weighted-average actuarial assumptions used to determine expense were as follows:

	Pension			OPEB
Percentages	2014	2013	2012	2014	2013	2012
Discount rate	4.72%	3.78%	4.54%	4.47%	3.48%	4.36%
Expected return on plan assets	7.50%	7.50%	7.50%	N/A	N/A	N/A
Compensation increase	4.00%	3.43%	3.69%	N/A	N/A	N/A
Health care cost trend rate (employees under 65)	N/A	N/A	N/A	6.49%	6.64%	6.91%
Ultimate health care cost trend rate	N/A	N/A	N/A	4.50%	4.50%	4.50%
Year ultimate trend reached	N/A	N/A	N/A	2028	2028	2028

The discount rate was based on a yield curve 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 on pension plan assets, net of fees, was approximately 6% in 2014, 17% in 2013, and13% in 2012.

Assumed healthcare cost trend rates have an 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. The 2015 assumed healthcare cost trend rate for employees under 65 is 6.49%. It is assumed the rate will decrease gradually to an ultimate rate of 4.5% in 2028 and will remain at that level. A one-percentage point change in the assumed healthcare cost trend rates would have the following effects on OPEB:

Millions	One % pt. Increase		One % pt. Decrease
Effect on total service and interest cost components	$	1	$	(1)
Effect on accumulated benefit obligation		19		(16)

Cash Contributions

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

	Pension
Millions	Qualified		Non-qualified		OPEB
2013	$	200	$	16	$	23
2014		200		33		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 in2014 were voluntary and were made with cash generated from operations.

The non-qualified pension and OPEB plans are not funded and are not subject to any minimum regulatory funding requirements. Benefit payments for each year represent supplemental pension payments and claims paid for medical and life insurance.We anticipate our 2015supplemental pension and OPEB payments will be made from cash generated from operations.

Benefit Payments

The following table details expected benefit payments for the years 2015through 2024:

Millions	Pension		OPEB
2015	$	180	$	23
2016		186		23
2017		191		23
2018		196		23
2019		201		23
Years 2020 - 2024		1,069		107

Asset Allocation Strategy

Our pension plan asset allocation at December 31, 2014 and 2013, and target allocation for 2015, are as follows:

	Target Allocation 2015	Percentage of Plan Assets December 31,
		2014	2013
Equity securities	60% to 70%	68%	70%
Debt securities	20% to 30%	23	21
Real estate	2% to 8%	4	4
Commodities	4% to 6%	5	5
Total		100%	100%

The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to achieve our target average long-term rate of return of 7.5%.While we believe we can achieve a long-term average rate of return of 7.5%, we cannot be certain that the portfolio will perform to our expectations. Assets are strategically allocated among equity, debt, and other investments in order to achieve a diversification level that reduces 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 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. 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 plans' assets in high quality debt securities. The average credit rating of the debt portfolio exceeded A+ as of December 31, 2014 and 2013. 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 years atboth December 31, 2014 and 2013.

The investment of pension plan assets in securities issued by UPCis explicitly prohibited by the plan 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 (the Trustee). 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 real estate investments and bond investments registered with the Securities and Exchange Commission. The real estate investments are traded actively on public exchanges. The share prices for these investments are published at the close of each business day. The Plan's holdings of real estate investments are classified as Level 1 investments. The bond investments are not traded publicly, but the underlying assets held in these funds are traded on active markets and the prices for these assets are readily observable. The Plan's holdings in bond investments are classified as Level 2 investments.

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

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

Corporate Stock – This investment category consists of common and preferred stock issued by U.S. and non-U.S. corporations. Most common shares are traded actively on exchanges and price quotes for these shares are readily available. Common stock is classified as a Level 1 investment. Preferred shares included in this category are valued using a bid evaluation process with bid data provided by independent pricing sources. Preferred stock is classified as a Level 2 investment.

Venture Capital and Buyout Partnerships – This investment category is comprised of interests in limited partnerships that invest primarily in privately-held companies. 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 the application of public market multiples to private company cash flows, market transactions that provide valuation information for comparable companies, and other methods. The fair value recorded by the Plan is calculated using the net asset value (NAV) per share, which is derived from the valuation method described here. The Plan's holdings of limited partnership interests are classified as Level 3 investments.

Real Estate Partnerships– Most of the Plan's real estate investments are interests in partnerships or other commingled funds. Valuations for the holdings in this category are not based on readily observable inputs and are primarily derived from property appraisals. The fair value recorded by the Plan is calculated using the NAV per share, which is derived from the valuation method described here. The Plan's interests in real estate partnerships and other commingled funds are classified as Level 3 investments.

Common Trust and Other Funds – Common trust funds are comprised of shares or units in commingled funds that are not publicly traded. The underlying assets in these funds (U.S. stock funds, non-U.S. stock funds, commodity funds, and short term investment funds) 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.

This category also includes investments in limited liability companies that invest in publicly-traded convertible securities, commodities, and other assets. The limited liability company investments are funds that invest in both long and short positions in convertible securities, stocks, commodities, and fixed income securities. The underlying securities held by the funds are traded actively on exchanges and price quotes for these investments are readily available. Interests in the limited liability companies are classified as Level 2 investments.

5. Stock Options and Other Stock Plans

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 awards of restricted shares under this plan.

In April 2000, the shareholders approved the Union Pacific Corporation 2000 Directors Plan (DirectorsPlan) whereby 2,200,000 shares of our common stock were reserved for issuance to our non-employeedirectors. Under the Directors Plan, each non-employee director, upon his or her initial election to theBoard of Directors, receives a grant of 4,000 retention shares or retention stock units. Prior to December31, 2007, each non-employee director received annually an option to purchase at fair value a number ofshares of our common stock, not to exceed 20,000 shares during any calendar year, determined bydividing 60,000 by 1/3 of the fair market value of one share of our common stock on the date of suchBoard of Directors meeting, with the resulting quotient rounded up or down to the nearest 50 shares. InSeptember 2007, the Board of Directors eliminated the annual payment of options for 2008 and all futureyears. As of December 31, 2014, 36,000 restricted shares and 78,000 options were outstanding underthe Directors Plan.

The Union Pacific Corporation 2004 Stock Incentive Plan (2004 Plan) was approved by shareholders inApril 2004. The 2004 Plan reserved 84,000,000 shares of our common stock for issuance, plus anyshares subject to awards made under previous plans 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 awardsmay be granted to eligible employees of the Corporation and its subsidiaries. Non-employee directors arenot eligible for awards under the 2004 Plan. As of December 31, 2014, 4,338,691options and 3,677,642retention shares and stock units were outstanding under the 2004 Plan. We no longer grant any stock options or other stock or unit awards under this plan.

The Union Pacific Corporation 2013 Stock Incentive Plan (2013 Plan) was approved by shareholders inMay 2013. The 2013 Plan reserved 78,000,000 shares of our common stock for issuance, plus anyshares subject to awards made under previous plans as of February 28, 2013, that are subsequently cancelled, expired, forfeited or otherwise not issued under previous plans.Under the 2013 Plan, non-qualified options, incentive stock options, retention shares, stock units, and incentive bonus awards may begranted to eligible employees of the Corporation and its subsidiaries. Non-employee directors are noteligible for awards under the 2013 Plan. As of December 31, 2014, 969,822 options and 1,307,905 retention shares and stock units were outstanding under the 2013 Plan.

Pursuant to the above plans 77,786,772;79,574,896; and 64,337,040shares of our common stock wereauthorized and available for grant at December 31, 2014, 2013, and 2012, respectively.

Stock-Based Compensation–We have several stock-based compensation plans under which employees and non-employee directors receive stock options, nonvested retention shares, and nonvested stock units. We refer to the nonvested shares and stock units collectively as “retention awards”. We have elected to issue treasury shares to cover option exercises and stock unit vestings, while new shares are issued when retention shares are granted.

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

Millions	2014		2013		2012
Stock-based compensation, before tax:
Stock options	$	21	$	19	$	18
Retention awards		91		79		75
Total stock-based compensation, before tax	$	112	$	98	$	93
Excess tax benefits from equity compensation plans	$	118	$	76	$	100

Stock Options – We estimate the fair value of our stock option awards using the Black-Scholes option pricing model. The table below shows the annual weighted-average assumptions used for valuation purposes:

Weighted-Average Assumptions		2014		2013		2012
Risk-free interest rate		1.6%		0.8%		0.8%
Dividend yield		2.1%		2.1%		2.1%
Expected life (years)		5.2		5.0		5.3
Volatility		30.0%		36.2%		36.8%
Weighted-average grant-date fair value of options granted	$	20.18	$	17.49	$	15.65

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 2014 is presented below:

	Options (thous.)	Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term	Aggregate Intrinsic Value (millions)
Outstanding at January 1, 2014	7,443	$	40.07	5.8 yrs.	$	327
Granted	989		87.56	N/A		N/A
Exercised	(2,961)		30.59	N/A		N/A
Forfeited or expired	(84)		68.48	N/A		N/A
Outstanding at December 31, 2014	5,387	$	53.56	5.8 yrs.	$	353
Vested or expected to vest	5,325	$	53.30	5.8 yrs.	$	351
at December 31, 2014
Options exercisable at December 31, 2014	3,350	$	40.69	4.4 yrs.	$	263

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, 2014, are subject to performance or market-based vesting conditions.

At December 31, 2014, there was $15 million of unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted-average period of 1year. Additional information regarding stock option exercises appears in the table below:

Millions	2014		2013		2012
Intrinsic value of stock options exercised	$	194	$	112	$	244
Cash received from option exercises		54		51		84
Treasury shares repurchased for employee payroll taxes		(24)		(21)		(30)
Tax benefit realized from option exercises		74		43		93
Aggregate grant-date fair value of stock options vested		17		16		16

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 2014 were as follows:

	Shares (thous.)	Weighted-Average Grant-Date Fair Value
Nonvested at January 1, 2014	3,712	$	49.02
Granted	871		88.14
Vested	(1,080)		31.33
Forfeited	(100)		57.82
Nonvested at December 31, 2014	3,403	$	64.39

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, 2014, there was $87 million of total unrecognized compensation expense related to nonvested retention awards, which is expected to be recognized over a weighted-average period of 1.6 years.

Performance Retention Awards – In February 2014, our Board of Directors approved performance stock unit grants. Other than different performance targets, the basic terms of these performance stock units are identical to those granted in February 2012 and February 2013, including using annual return on invested capital (ROIC) as the performance measure. We define ROIC as net operating profit adjusted for interest expense (including interest on the present value of operating leases) and taxes on interest divided by average invested capital adjusted for the present value of operating leases.

Stock units awarded to selected employees under these grants are subject to continued employment for 37 months and the attainment of certain levels of ROIC.We expense the fair value of the units that are probable of being earned based on our forecasted ROIC over the 3-year performance period. We measure the fair value of these performance stock units based upon the closing price of the underlying common stock as of the date of grant, reduced by the present value of estimated future dividends. Dividend equivalents are paid to participants only after the units are earned.

The assumptions used to calculate the present value of estimated future dividends related to the February 2014grant were as follows:

	2014
Dividend per share per quarter	$	0.455
Risk-free interest rate at date of grant		0.7%

Changes in our performance retention awards during 2014 were as follows:

	Shares (thous.)	Weighted-Average Grant-Date Fair Value
Nonvested at January 1, 2014	1,888	$	53.70
Granted	456		83.06
Vested	(661)		44.94
Forfeited	(100)		61.36
Nonvested at December 31, 2014	1,583	$	65.33

At December 31, 2014, there was $36 million of total unrecognized compensation expense related to nonvested performance retention awards, which is expected to be recognized over a weighted-average period of 1year. This expense is subject to achievement of the ROIC levels established for the performance stock unit grants.

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) for which lives 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 lives 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 lives 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. In addition, we determine if the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by our depreciation studies. Any deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the applicable classes of assets.

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. 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 track assets and other road properties, which is typically performed by our employees, and for track line expansion and other capacity projects. Costs that are directly attributable to capital projects (including overhead costs) 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.

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. These costs are allocated using appropriate statistical bases. Total expense for repairs and maintenance incurred was$2.4 billion for 2014, $2.3 billion for 2013, and $2.1billion for 2012.

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.

We lease certain locomotives, freight cars, and other property. The Consolidated Statements of Financial Position as of December 31, 2014 and 2013 included $2,454 million, net of $1,210 million of accumulated depreciation, and $2,486 million, net of $1,092 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, 2014, were as follows:

Rent expense for operating leases with terms exceeding one month was $593million in 2014, $618 million in 2013, and $631 million in 2012. 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.

Nature Of Operations [Text Block]

For purposes of this report, unless the context otherwise requires, all references herein to the “Corporation”, “Company”, “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 operating in the U.S. Our network includes31,974route miles, linking Pacific Coast and Gulf Coast ports with the Midwest and Eastern U.S. gateways and providing several corridors to key Mexican gateways. We own 26,012 miles and operate on the remainder pursuant to trackage rights or leases. 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 we provide and review 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. The following table provides freight revenue by commodity group:

Commitments and Contingencies [Text Block]

18.Commitments and Contingencies

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

Personal Injury – The cost of personal injuries to employees and others related to our activities is charged to expense based on estimates of the ultimate cost and number of incidents each year. We use an actuarial analysis to measure the expense and liability, including unasserted claims. The Federal Employers' Liability Act (FELA) governs compensation for work-related accidents. Under FELA, damages are assessed based on a finding of fault through litigation or out-of-court settlements. We offer a comprehensive variety of services and rehabilitation programs for employees who are injured at work.

Our personal injury liability is not discounted to present value due to the uncertainty surrounding the timing of future payments. Approximately 93% of the recorded liability is related to asserted claims and approximately 7% is related to unasserted claims at December 31, 2014. 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 $335 million to $368 million. We record an accrual at the low end of the range as no amount of loss within the range is more probable than any other. Estimates can vary over time due to evolving trends in litigation.

Our personal injury liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	294	$	334	$	368
Current year accruals		96		87		121
Changes in estimates for prior years		9		(38)		(58)
Payments		(64)		(89)		(97)
Ending balance at December 31	$	335	$	294	$	334
Current portion, ending balance at December 31	$	111	$	82	$	95

In conjunction with the liability update performed in 2014, we also reassessed our estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2014, and 2013.

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

• The ratio of future claims by alleged disease would be consistent with historical averages adjusted for inflation.
• 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, 2014. 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 $126 million to $135 million. We record an accrual at the low end of the range as no amount of loss within the range is more probable than any other.

Our asbestos-related liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	131	$	139	$	147
Accruals/(Credits)		1		2		(2)
Payments		(6)		(10)		(6)
Ending balance at December 31	$	126	$	131	$	139
Current portion, ending balance at December 31	$	8	$	9	$	8

In conjunction with the liability update performed in 2014, we also reassessed our estimated insurance recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2014, and 2013.The amounts recorded for asbestos-related liabilities and related insurance recoveries were based on currently known facts. However, future events, such as the number of new claims filed each year, average settlement costs, and insurance coverage issues, could cause the actual costs and insurance recoveries to be higher or lower than the projected amounts. Estimates also may vary in the future if strategies, activities, and outcomes of asbestos litigation materially change; federal and state laws governing asbestos litigation increase or decrease the probability or amount of compensation of claimants; and there are material changes with respect to payments made to claimants by other defendants.

EnvironmentalCosts– We are subject to federal, state, and local environmental laws and regulations. We have identified 270 sites at which we are or may be liable for remediation costs associated with alleged contamination or for violations of environmental requirements. This includes 29 sites that are the subject of actions taken by the U.S. government, 16of 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 perform, with assistance of our consultants, environmental assessments on the property. We expense the cost of the assessments as incurred. We accrue the cost of remediation where our obligation is probable and such costs can be reasonably estimated. Our environmental liability is not discounted to present value due to the uncertainty surrounding the timing of future payments.

Our environmental liability activity was as follows:

Millions	2014		2013		2012
Beginning balance	$	171	$	170	$	172
Accruals		56		58		48
Payments		(45)		(57)		(50)
Ending balance at December 31	$	182	$	171	$	170
Current portion, ending balance at December 31	$	60	$	53	$	50

The environmental liability includes future costs for remediation and restoration of sites, as well as ongoing monitoring costs, but excludes any anticipated recoveries from third parties. Cost estimates are based on information available for each site, financial viability of other potentially responsible parties, and existing technology, laws, and regulations. The ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties, site-specific cost sharing arrangements with other potentially responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs. Estimates of liability may vary over time due to changes in federal, state, and local laws governing environmental remediation. Current obligations are not expected to have a material adverse effect on our consolidated results of operations, financial condition, or liquidity.

Insurance – The Company has a consolidated, wholly-owned captive insurance subsidiary (the captive), that provides insurance coverage for certain risks including FELA claims and property coverage which are subject to reinsurance. The captive entered into annual reinsurance treaty agreements that insure workers compensation, general liability, auto liability and FELA risk. The captive cedes a portion of its FELA exposure through the treaty and assumes a proportionate share of the entire risk. The captive receives direct premiums, which are netted against the Company's premium costs in other expenses in the Consolidated Statements of Income. The treaty agreements provide for certain protections against the risk of treaty participants' non-performance, and we do not believe our exposure to treaty participants' non-performance is material at this time. In the event the Company leaves the reinsurance program, the Company is not relieved of its primary obligation to the policyholders for activity prior to the termination of the treaty agreements. We record both liabilities and reinsurance receivables using an actuarial analysis based on historical experience in our Consolidated Statements of Financial Position.

Guarantees – AtDecember 31, 2014,and 2013, we were contingently liable for $82 million and $299 million in guarantees. We have recorded liabilities of $0.3 million and $1 million for the fair value of these obligations as of December 31, 2014, and 2013, respectively. We entered into these contingent guarantees in the normal course of business, and they include guaranteed obligations related to our equipment financings and affiliated operations. The final guarantee expires in 2022. We are not aware of any existing event of default that would require us to satisfy these guarantees. We do not expect that these guarantees will have a material adverse effect on our consolidated financial condition, results of operations, or liquidity.

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

Gain Contingency– UPRR and Santa Fe Pacific Pipelines (SFPP, a subsidiary of Kinder Morgan Energy Partners, L.P.) currently are engaged in a proceeding to resolve the fair market rent payable to UPRR commencing on January 1, 2004, for pipeline easements on UPRR rights-of-way (Union Pacific Railroad Company vs. Santa Fe Pacific Pipelines, Inc., SFPP, L.P., Kinder Morgan Operating L.P. “D” Kinder Morgan G.P., Inc., et al., Superior Court of the State of California for the County of Los Angeles, filed July 28, 2004). In February 2007, a trial began to resolve this issue, and in May 2012, the trial judge rendered an opinion establishing the fair market rent and entering judgment for back rent, including prejudgment interest. SFPP appealed the judgment. On November 5, 2014, the Second District Circuit Court of Appeal in California issued an opinion holding that UPRR was not entitled to collect rent from SFPP for easements on the portions of the property acquired solely through Federal government land grantsissued during the 1800s. The Appellate Court also reversed the award of prejudgment interest and remanded the case to the trial court. A favorable final judgment may materially affect UPRR's results of operations in the period of any monetary recoveries. Due to the uncertainty regarding the amount and timing of any recovery or any subsequent proceedings, we consider this a gain contingency and do not reflect any amounts in the Consolidated Financial Statements as of December 31, 2014.

Accounts Receivable [Abstract]

Accounts Receivable [Text Block]

11. Accounts Receivable

Accounts receivable includes freight and other receivables reduced by an allowance for doubtful accounts. The allowanceis based upon historical losses, credit worthiness of customers, and current economic conditions.At December 31, 2014, and 2013, our accounts receivable were reduced by $5 million and $1 million, respectively. Receivables not expected to be collected in one year and the associated allowancesare classified as other assets in our Consolidated Statements of Financial Position. At December 31, 2014, and 2013,receivables classified as other assets were reduced by allowances of $16 million and $22 million, respectively.

Receivables Securitization Facility – On July 29, 2014, we completed the renewal of our receivables securitization facility. The new $650 million, 3-year facility replaces the prior $600 million, 364-day facility. Under the facility, the Railroad sells most of its eligible third-party receivables to Union Pacific Receivables, Inc. (UPRI), a wholly-owned, bankruptcy-remote subsidiary that may subsequently transfer, without recourse, an undivided interest in accounts receivable to 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.

The amount outstanding under the facility was $400 millionand $0 at December 31, 2014, and December 31, 2013, respectively. The facility was supported by $1.2 billion and $1.1 billion of accounts receivable as collateral at December 31, 2014, and December 31, 2013, respectively, which, as a retained interest, is included in accounts receivable, net in our Consolidated Statements of Financial Position.

The outstanding amount the Railroad is allowed to maintain under the facility, with a maximum of $650 million, may fluctuate based on the availability of eligible receivables and is directly affected by business volumes and credit risks, including receivables payment quality measures such as default and dilution ratios. If default or dilution ratios increase one percent, the allowable outstanding amount under the facility would not materially change.

The costs of the receivables securitization facility include interest, which will vary based on prevailing benchmark and commercial paper rates, program fees paid to participating banks, commercial paper issuing costs, and fees of participating banks for unused commitment availability. The costs of the receivables securitization facility are included in interest expense and were $4 million, $5 million and $3 million for 2014, 2013, and 2012, respectively.
