February 4, 2011 

Fellow Shareholders: 

As  our  country  and  our  Company  emerged  from  the  shadow  of  the  economic  recession,  the  men  and 
women of Union Pacific demonstrated agility and resiliency to meet the evolving transportation needs of 
our customers.  The result was a break-out performance in 2010 that culminated in a record year.   

The  actions  taken  to  support  our  core  strategy  of  safety,  service  and  customer  value  positioned  us  to 
successfully  handle  growing  volumes.    With  strengthening  business  demand,  our  service  remained 
excellent and we achieved many new safety records.  Customers gave us their highest satisfaction marks 
ever,  and  many  rewarded  us  with  new  business.    They  recognize  the  value  of  our  diverse  service 
offerings and the efficiency we add to their supply chains.  In return, we’ve kept our commitment, making 
strategic investments in infrastructure, facilities, equipment and technology.    

These investments further support UP’s commitment to our shareholders to increase profitability and grow 
financial returns.  In 2010, we achieved new financial milestones, including a 70.6 percent operating ratio 
and  a  10.8  percent  return  on  invested  capital.    We  also  returned  more  cash  directly  to  shareholders, 
increasing  the  dividend  41  percent  and  repurchasing  nearly  $1.25  billion  of  shares.    UP’s  stock  price 
reached new highs in 2010, increasing 45 percent and outpacing the S&P 500 by more than 30 points. 

With the foundation of a record year as our springboard, we look forward to even greater opportunities to 
grow  our  business,  with  the  same  commitment  to  safely  serving  our  customers  and  increasing  our 
financial  returns.    One  clear  opportunity  comes  from  an  expanding  global  economy  and  greater 
international  demand  for  freight  transportation,  which  already  accounts  for  almost  one  third  of  UP’s 
revenue  base.    The  growing  U.S.  population  alone  is  expected  to  increase  freight  demand  30  percent 
over  the  next  20  years  and  further  crowd  our  highways.    The  Department  of  Transportation  recognized 
that need when it set the goal of developing strategies to attract 50 percent of all shipments 500 miles or 
greater to intermodal rail.  They see what we see every day – America needs more rail. 

Our  strategic  capital  investments  will  help  us  tap  into  that  future  growth  potential.    This  is  illustrated  by 
projects such as double tracking our Sunset Corridor, where we are speeding global commerce between 
Asia  and  our  nation’s  growing  consumer  base.    This  is  a  business  model  that  works  –  invest,  grow  the 
business, increase returns and invest again. 

Great service, coupled with our logistics expertise and continued investment for the future, enables UP to 
offer  a  strong  door-to-door  value  proposition.    Through  efforts  such  as  the  “You’ll  Find  Us”  advertising 
campaign, customers who never before considered rail are turning to us to coordinate shipments across 
town,  across  the  country  and  around  the  world.    Shippers  also  have  a  growing  appreciation  for  UP’s 
“green” profile and our ability to deliver safe, fuel-efficient service. 

It’s  clear  that  the  opportunity  to  grow  and  prosper  is  well  within  our  reach.    This  is  the  mission  of  the 
43,000-plus Union Pacific employees who are “dedicated to serve.”  Through innovation, teamwork and 
some  good  old-fashioned  hard  work,  we  have  set  a  course  for  growth  designed  to  generate  strong 
financial returns in the years ahead.

OPERATIONS 

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

two-thirds  of 

2010 Freight Revenue 

Operations  –  UPRR  is  a  Class  I  railroad 
operating  in  the  U.S.  We  have  31,953  route 
miles,  linking  Pacific  Coast  and  Gulf  Coast 
ports  with  the  Midwest  and  eastern  U.S. 
gateways  and  providing  several  corridors  to 
the 
key  Mexican  gateways.  We  serve 
western 
the  country  and 
maintain  coordinated  schedules  with  other 
rail  carriers  to  move  freight  to  and  from  the 
the 
Atlantic  Coast, 
the  Pacific  Coast, 
Southeast, 
the  Southwest,  Canada,  and 
Mexico.  Export  and  import  traffic  moves 
through  Gulf  Coast  and  Pacific  Coast  ports 
the  Mexican  and  Canadian 
and  across 
borders.  Our  freight  traffic  consists  of  bulk, 
manifest,  and  premium  business.  Bulk  traffic  is  primarily  coal,  grain,  rock,  or  soda  ash  in  unit  trains  – 
trains  transporting  a  single  commodity  from  one  source  to  one  destination.  Manifest  traffic  is  individual 
carload  or  less  than  train-load  business,  including  commodities  such  as  lumber,  steel,  paper,  and  food. 
The  transportation  of  finished  vehicles  and  intermodal  containers  is  part  of  our  premium  business.  In 
2010, we generated freight revenues totaling $16.1 billion from the following six commodity groups: 

Agricultural – Transporting agricultural products generated 19% of our freight revenues in 2010. Included 
in  this  commodity  group  are  whole  grains,  products  produced  from  grains,  and  food  and  beverage 
products, in addition to corn for ethanol production and its by products. With access to most major grain 
markets,  we  provide  a  critical  link  between  the  Midwest  and  western  producing  areas  and  export 
terminals  in  the  Pacific  Northwest  (the  PNW)  and  Gulf  ports,  as  well  as  Mexico.  Unit  trains  of  grain 
efficiently shuttle between domestic markets or export terminals and producers. We also serve significant 
domestic  markets,  including  grain  processors,  animal  feeders,  and  ethanol  producers  in  the  Midwest, 
West,  South,  and  Rocky  Mountain  region.  Primary  food  commodities  consist  of  a  variety  of  fresh  and 
frozen fruits and vegetables, dairy products, and beverages,  which  are  moved  to  major  U.S.  population 
centers for distribution and consumption. Express Lane and Produce Unit Train are premium perishable 
services  that  compete  with  the  trucking  industry  by  moving  fruits  and  vegetables  from  the  PNW  and 
California to destinations in the East. We transport frozen meat and poultry to the West Coast ports for 
export, while beverages, primarily beer, enter the U.S. from Mexico.  

Automotive  –  We  are  the  largest  automotive  carrier  west  of  the  Mississippi  River,  serving  vehicle 
assembly  plants  and  distributing  imported  vehicles  from  West  Coast  ports  and  Houston.  We  operate  or 
access 43 vehicle distribution centers covering most major western U.S. cities. In addition to transporting 
finished  vehicles,  we  provide  expedited  handling  of  automotive  parts  in  both  boxcars  and  intermodal 
containers  to  several  assembly  plants.  We  carry  automotive  materials  bound  for  assembly  plants  in 
Mexico,  the  U.S.,  and  Canada,  and  we  also  transport  finished  vehicles  from  manufacturing  facilities  in 
Canada and Mexico. In 2010, transportation of finished vehicles and automotive materials accounted for 
8% of our freight revenues. 

Chemicals – Transporting chemicals provided 15% of our freight revenues in 2010. Our unique franchise 
enables us to serve the chemical producing areas along the Gulf Coast, as well as the Rocky Mountain 
region.  Two-thirds  of  the  chemicals  business  consists  of  industrial  chemicals,  plastics,  and  liquid 
petroleum products. Plastics customers also use our storage-in-transit yards for intermediate storage of 
plastic resins. Soda ash shipments originate in southwestern Wyoming and California, destined primarily 
for glass producing markets in the East, the West, and abroad. Fertilizer movements originate primarily in 

6 

 
 
 
 
 
 
the Gulf Coast region, as well as the West and Canada, bound for major agricultural users in the Midwest 
and the western U.S.  

Energy – Coal transportation accounted for 22% of our 2010 freight revenues. Our transportation network 
allows  us  to  transport  coal  and  coke  to  utilities,  industrial  facilities,  interchange  points,  and  water 
terminals.    Water  terminals  provide  access  to  the  West  and  Gulf  Coasts  for  export,  and  rail/barge 
interchange facilities on the Mississippi and Ohio Rivers and the Great Lakes. We serve mines located in 
the Southern Powder River Basin (SPRB) of Wyoming, Colorado, Utah, southern Wyoming, and southern 
Illinois.  SPRB  coal  represents  the  largest  segment  of  the  market,  as  utilities  continue  to  favor  its  lower 
cost and low-sulfur content.  

Industrial  Products  –  Our  extensive  network  enables  us  to  move  numerous  commodities  between 
thousands  of  origin  and  destination  points  throughout  North  America.  Lumber  shipments  originate 
primarily  in  the  PNW  and  Canada  for  destinations  throughout  the  U.S.  for  new  home  construction  and 
repair and remodeling. Commercial and highway construction drives shipments of steel and construction 
products,  consisting  of  rock,  cement,  and  roofing  materials.  Paper  and  consumer  goods,  as  well  as 
furniture and appliances, are shipped to major metropolitan areas for consumers. Nonferrous metals and 
industrial  minerals  are  moved  for  industrial  manufacturing.  In  addition,  we  provide  efficient  and  safe 
transportation  for  government  entities  and  waste  companies.  In  2010,  transporting  industrial  products 
provided 16% of our freight revenues.  

Intermodal – Our intermodal business, which represented 20% of our freight revenues in 2010, includes 
international  and  domestic  shipments.  International  business consists of imported  or  exported  container 
traffic  that  arrives  at,  or  departs  from,  West  Coast  ports  via  ocean  vessel.  Domestic  business  includes 
domestic  container  and  trailer  traffic  for  major  retailers  and  other  U.S.  businesses  that  is  usually  sold 
through  intermodal  marketing  companies  (primarily  shipper  agents  and  consolidators)  and  truckload 
carriers.  

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,  which 
generally  has  a  peak  shipping  season  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  from  year  to  year  depending  upon  various  factors,  including  the  strength  of  domestic  and 
international  economies  and  currencies  and  the  strength  of  harvests  and  market  prices  of  agricultural 
products. In response to an annual request delivered by 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 issue 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,  2010  and  2009,  we  had  a  working  capital  surplus,  which  in  2010 
continued to be the result of our decision in 2009 to maintain additional cash reserves to enhance liquidity 
in response to uncertain economic conditions.  Historically, we have had a working capital deficit, which is 
common in our industry and does not indicate a lack of liquidity. We maintain adequate resources and, 
when  necessary,  have  access  to  capital  to  meet  any  daily  and  short-term  cash  requirements,  and  we 
have sufficient financial capacity to satisfy our current liabilities. 

Competition  –  We  are  subject  to  competition  from  other  railroads,  motor  carriers,  ship  and  barge 
operators,  and  pipelines.  Our  main  rail  competitor  is  Burlington  Northern  Santa  Fe  Corporation.  Its  rail 
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  energy).  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  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 and barges are able to use public rights-of-way maintained by public entities. Any future 
improvements or expenditures materially increasing the quality or reducing the costs of these alternative 
modes of transportation, or legislation releasing motor carriers from their size or weight limitations, could 
have a material adverse effect on our business.

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  to  entry  in  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 
suppliers  (one  domestic  and  one  international)  that  meet  our  specifications.  Rail  is  critical  for  both 
maintenance of our network and replacement and improvement or expansion of our network and facilities. 
Rail manufacturing also has high barriers to 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  86%  of  our  42,884  full-time-equivalent  employees  are  represented  by  14 
major  rail  unions.  Current  labor  agreements  became  subject  to  modification  on  January  1,  2010.    In 
January 2010, we began the current round of negotiations with the unions. Existing agreements remain in 
effect and will continue to remain in effect until new agreements are reached or the Railway Labor Act’s 
procedures  (which  include  mediation,  cooling-off  periods,  and  the  possibility  of  Presidential  Emergency 
Boards  and  Congressional  intervention)  are  exhausted.  Contract  negotiations  with  the  various  unions 
generally  take  place  over  an  extended  period  of  time,  and  we  rarely  experience  work  stoppages  during 
negotiations. 

Railroad  Security  –  Operating  a  safe  and  secure  railroad  is  first  among  our  critical  priorities  and  is  a 
primary  responsibility  of  all  our  employees.    This  emphasis  helps  us  protect  the  public,  our  employees, 
our  customers,  and  operations  across  our  rail  network.    Our  security  efforts  rely  upon  a  wide  variety  of 
measures  including  employee  training,  cooperation  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  to 
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  225 
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  to  identify  ways  to  increase 
preparedness and to improve security. 

We  have  an  emergency  response  management  center,  which  operates  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 we serve 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 new Transportation Security Agency regulations that took effect on April 
1,  2009,  we  deployed  new  information  systems  and  instructed  employees  in  tracking  and  documenting 
the handoff of Rail Security Sensitive Material 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. 

Cooperation  with  Federal,  State,  and  Local  Government  Agencies  –  We  work  closely  with  government 
agencies  ranging  from  the  DOT  and  the  Department  of  Homeland  Security  (DHS)  to  local  police 
departments,  fire  departments,  and  other  first  responders.    In  conjunction  with  DOT,  DHS,  and  other 
railroads, we sponsor Operation Respond, which provides first responders with secure links to electronic 
railroad  resources,  including  mapping  systems,  shipment  records,  and  other  essential  information 
required by emergency personnel to respond to accidents and other situations.  We also participate in the 

8 

 
 
 
 
 
 
 
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,  formerly  the  U.S.  Customs 
Service), and the Military Transport Management Command to 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-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  –  Along  with  other  railroads,  we  work  with  the 
American  Chemistry  Council  to  train  more  than  200,000  emergency  responders  each  year.    We  work 
closely with our chemical shippers to establish plant security plans, and we continue to take steps to more 
closely  monitor  and  track  hazardous  materials  shipments.    In  cooperation  with  the  Federal  Railroad 
Administration (FRA) and other railroads, 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. The STB has launched wide-ranging proceedings to explore whether to expand rail 
regulation; we will actively participate in these proceedings. Additionally, several bills were introduced in 
the  U.S.  Senate  in  early  2011  that  would  expand  the  regulatory  authority  of  the  STB  and  could  include 
new antitrust provisions. We are closely monitoring these proposed bills.  

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 final rules governing installation of Positive Train Control 
(PTC)  by  the  end  of  2015.    Although  still  under  development,  PTC  is  a  collision  avoidance  technology 
intended  to  override  locomotive  controls  and  stop  a  train  before  an  accident.    The  FRA  acknowledged 
that  projected  costs  will  exceed  projected  benefits  by  a  ratio  of  about  22  to  one.    We  expect  to  invest 
approximately $250 million in the development of PTC during 2011.   

DOT,  the  Occupational  Safety  and  Health  Administration,  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. On October 16, 2008, President Bush signed the Rail 
Safety  Improvement  Act  of  2008  into  law,  which,  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 areas 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 
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  17  to  the  Consolidated  Financial 
Statements in Item 8, Financial Statements and Supplementary Data.

Item 1A. Risk Factors 

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,  and  improve  operations  at  our  yards  and  other  facilities,  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 increases or decreases of demand for rail service with respect to one or more of 
our commodity groups, or other events that could  have a negative impact on 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 of demand for rail services with respect to 
one or more of our commodity groups, 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 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,  railroad  carriers  must  implement  PTC  by  the  end  of  2015, 
which could have a material adverse effect on our ability to make other capital investments.  One or more 
consolidations of Class I railroads could also lead to increased regulation of the rail industry. 

We  Are  Required  to  Transport  Hazardous  Materials  –  Federal  laws  require  railroads,  including  us,  to 
transport hazardous materials regardless of risk or potential exposure to loss. Any rail accident or other 
incident  or  accident  on  our  network,  at  our  facilities,  or  at  the  facilities  of  our  customers  involving  the 
release  of  hazardous  materials,  including  toxic  inhalation  hazard  (or  TIH)  materials  such  as  chlorine, 
could  involve  significant  costs  and  claims  for  personal  injury,  property  damage,  and  environmental 
penalties  and  remediation,  which  could  have  a  material  adverse  effect  on  our  results  of  operations, 
financial condition, and liquidity. 

We May Be Affected by General Economic Conditions – Prolonged severe adverse domestic and global 
economic conditions or disruptions of financial and credit markets, including the availability of short- and 
long-term debt financing, 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 and barges 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  releasing  motor  carriers  from  their  size  or 
weight  limitations,  could  have  a  material  adverse  effect  on  our  results  of  operations,  financial  condition, 

10 

 
 
 
 
 
 
 
and  liquidity.  Additionally,  any  future  consolidation  of  the  rail  industry  could  materially  affect  the 
competitive environment in which we operate. 

Strikes  or  Work  Stoppages  Could  Adversely  Affect  Our  Operations  as  the  Majority  of  Our  Employees 
Belong  to  Labor  Unions  and  Labor  Agreements  –  The  U.S.  Class  I  railroads  are  party  to  collective 
bargaining agreements with various labor unions. 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.  

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  that  may  cause  business  interruptions,  including  line  outages  on  our  rail  network,  that  can 
adversely affect our entire rail network and result in increased costs, increased liabilities, and decreased 
revenue, 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 implement new technology, 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  we  experience  significant  disruption  or  failure  of  one  or  more  of  our  information  technology  systems, 
including computer hardware, software, and communications equipment, we could experience a 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  could  have  a  material  adverse  effect  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  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 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 
food  producers,  and  automakers  and  other 
fuels, 
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. 

farmers  and 

Rising or Elevated Fuel Costs and Whether We Are Able to Mitigate These Costs with Fuel Surcharges 
Could  Materially  and  Adversely  Affect  Our  Business  –  Fuel  costs  constitute  a  significant  portion  of  our 
transportation  expenses.  Diesel  fuel  prices  are  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  increased  fuel  expenses  through  revenue  from  fuel  surcharges,  we 
cannot be certain that we will always be able to mitigate rising or elevated fuel costs through surcharges. 
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.  International, 
political,  and  economic  circumstances  affect  fuel  prices  and  supplies.  Weather  can  also  affect  fuel 
supplies  and  limit  domestic  refining  capacity.  If  a  fuel  supply  shortage  were  to  arise,  higher  fuel  prices 
could, despite our fuel surcharge programs, have a material adverse effect 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 
deterioration of our financial condition could result in a reduction of our credit rating to below investment 
grade,  which  could  prohibit  or  restrict  us  from  utilizing  our  current  receivables  securitization  facility  or 
accessing  external  sources  of  short-  and  long-term  debt  financing  and  significantly  increase  the  costs 
associated  with  utilizing  the  receivables  securitization  facility  and  issuing  both  commercial  paper  and 
long-term debt.  

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 to our operations.  Additionally, 
for a high percentage of our rail purchases, we utilize two suppliers (one domestic and one international) 
that meet our specifications.  Rail is critical to our operations for rail replacement programs, maintenance, 

12 

 
 
 
 
 
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

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. 

RAIL FACILITIES 

In  addition  to  our  track  structure,  we  operate  numerous  facilities,  including  terminals  for  intermodal  and 
other freight; rail yards for train-building (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

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. 

2010 Capital Expenditures – During 2010, we made capital investments totaling $2.5 billion, nearly all of 
which was cash spending.  (See the capital expenditures table in Management’s Discussion and Analysis 
of Financial Condition and Results of Operations – Liquidity and Capital Resources – Financial Condition, 
Item 7.) 

15 

 
 
  
 
 
 
  
  
 
  
  
 
  
  
  
 
 
 
Infrastructure Expansion – With expected long-term growth in  the intermodal market, we commenced 
construction of a new intermodal terminal in Joliet, Illinois, in the spring of 2009 and completed the initial 
phase  in  August  2010.    This  new  facility  supports  customer  growth  by  increasing  the  Railroad’s 
international  and  domestic  container  capacity  and  improving  rail  traffic  efficiencies  in  Chicago,  the 
nation’s largest rail center.  Customers across our network benefit from the Joliet facility’s annual capacity 
of 500,000 intermodal containers.   

2011  Capital  Expenditures  –  In  2011,  we  expect  to  make  capital  investments  of  approximately  $3.2 
billion,  including  expenditures  for  PTC  of  approximately  $250  million.    We  may  revise  our  2011  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 2011 capital plan in Management’s Discussion and 
Analysis of Financial Condition and Results of Operations – 2011 Outlook, Item 7.) 

OTHER 

Equipment  Encumbrance  –  Equipment  with  a  carrying  value  of  approximately  $3.2  billion  and  $3.4 
billion  at  December  31,  2010  and  2009,  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. 

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.  

ENVIRONMENTAL MATTERS 

As we reported in our Annual Report on Form 10-K for 2005, the Environmental Protection Agency (EPA) 
considers  the  Railroad  a  potentially  responsible  party  for  the  Omaha  Lead  Site.  The  Omaha  Lead  Site 
consists of approximately 25 square miles of residential property in the eastern part of Omaha, Nebraska, 
allegedly impacted by air emissions from two former lead smelters/refineries. One refinery was operated 
by  ASARCO.  The  EPA  identified  the  Railroad  as  a  potentially  responsible  party  because  more  than  60 
years  ago  the  Railroad  owned  land  that  was  leased  to  ASARCO.  The  Railroad  disputes  both  the  legal 
and technical basis of the EPA’s allegations. It has nonetheless engaged in extensive negotiations with 
the EPA. The EPA issued a Unilateral Administrative Order with an effective date of December 16, 2005, 
directing  the  Railroad  to  implement  an  interim  remedy  at  the  site  at  an  estimated  cost  of  $50  million. 
Failure  to  comply  with  the  order  without  just  cause  could  subject  the  Railroad  to  penalties  of  up  to 
$37,500 per day and triple the EPA’s costs in performing the work. The Railroad believes it has just cause 
not  to  comply  with  the  order,  but  it  offered  to  perform  some  of  the  work  specified  in  the  order  as  a 
compromise. On August 5, 2009, the Railroad received a Special Notice Letter from EPA directing UPRR 

16 

 
 
 
 
 
 
 
 
 
 
to  perform  environmental  remediation  at  approximately  9,000  residential  yards  in  Omaha  and  to  take 
other remedial measures as part of a final remedy. The Railroad continues to contest its purported liability 
for these costs but has submitted an offer to the EPA to attempt to negotiate a resolution of the matter.  
On June 23, 2010, the Railroad filed suit in federal district court in Omaha, Nebraska against the EPA and 
its Administrator under the Freedom of Information Act (FOIA), the Administrative Procedure Act and the 
Federal Records Act asking the court to compel EPA to respond fully to outstanding FOIA requests and to 
prevent  EPA  from  destroying  records.    The  court  granted  the  Railroad  a  temporary  restraining  order 
prohibiting further document destruction.  On August 26, 2010, the Court entered an agreed Preliminary 
Injunction  preventing  destruction  of  records  by  EPA.    In  November  2010,  the  Railroad  reached  a 
tentative,  confidential  settlement  agreement  subject  to  further  negotiation  to  resolve  its  liability  at  the 
Omaha Lead Site.  The FOIA litigation has been stayed pending possible resolution of the case. 

As we reported in our Annual Report on Form 10-K for 2005, the Illinois Attorney General’s office filed a 
complaint against the Railroad in the Circuit Court for the Twentieth Judicial Circuit (St. Clair County) for 
injunctive  and  other  relief  on  November  28,  2005,  alleging  a  diesel  fuel  spill  from  an  above-ground 
storage tank in a rail yard in Dupo, St. Clair County, Illinois. The State of Illinois seeks to enjoin UPRR 
from further violations and a monetary penalty. The amount of the proposed penalty, although uncertain, 
could exceed $100,000.  

As we reported in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2010, we received 
notices from EPA Region 8 and U.S. Department of Justice (DOJ) alleging that we may be liable under 
federal environmental laws for violating the Clean Water Act and the Oil Pollution Prevention Act relating 
to  derailments  and  spills  and  UPRR’s  Spill  Prevention  Countermeasure  and  Control  Plans  and  its 
Stormwater Pollution Prevention Plans in Colorado, Utah, and Wyoming.  We cannot predict the ultimate 
impact of these proceedings because we are continuing to investigate and negotiate with the EPA Region 
8 and DOJ.  The amount of the proposed penalty, although uncertain, could exceed $100,000. 

We received notices from the EPA and state environmental agencies alleging that we are or may be liable 
under  federal  or  state  environmental  laws  for  remediation  costs  at  various  sites  throughout  the  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 

U.S. Customs and Border Protection (CBP) Dispute and Litigation – As we reported in our Quarterly 
Report on Form 10-Q for the quarter ended June 30, 2010, CBP directed its field offices to issue penalties 
against the Railroad in December 2007 for discoveries of illegal drugs in railcars crossing the border from 
Mexico.  The cars are in trains delivered by Mexican railroads directly to CBP; the Railroad receives the 
trains  only  after  CBP  inspects  them.    Additionally, CBP  imposed  or  reinstated  earlier  penalties  that  had 
been held in abeyance while the Railroad and CBP pursued a collective plan to address drug smuggling.  
In some instances, CBP seized railcars in which drugs were found.   

On  July  31,  2008,  the  Railroad  filed  a  complaint  in  the  U.S.  District  Court  for  the  District  of  Nebraska 
asking  the  court  to  enter  (1)  a  judgment  declaring  that  CBP’s  penalties  and  seizures  are  invalid  and 
unenforceable  and  (2)  preliminary  and  permanent  injunctions  prohibiting  CBP  from  enforcing  penalties 
and  holding  seized  cars  and  directing  CBP  to  refrain  from  issuing  additional  penalties  and  from  future 
equipment  seizures.    The  total  amount  of  penalties  assessed  against  the  Railroad  at  that  time  was 
approximately  $61.4  million.    The  parties  discussed  settlement,  and  the  case  in  the  District  Court  was 
stayed.  During this period, no new penalties were issued and no cars were seized.   

Settlement discussions were unsuccessful.  As a result, the Railroad reinstituted its lawsuit on February 
18, 2009.  U.S. Department of Justice (DOJ) then filed enforcement actions in the U.S. District Court for 
the Southern District of Texas on March 17, 2009, and in the U.S. District Court for the Southern District 
of California on March 18, 2009, and nine separate forfeiture complaints in the U.S. District Court for the 
District of Arizona on March 19, 2009 (covering ten seized cars).    

17 

 
 
 
 
 
 
 
 
 
The Railroad is awaiting a decision on its motion for Summary Judgment from the Nebraska court. The 
Railroad also filed motions in California, Texas, and Arizona to transfer (to Nebraska), dismiss or stay the 
cases  in  those  courts.    The  California  and  Texas  courts  granted  UP’s  motion  to  transfer  venue  to 
Nebraska.  The Arizona Court has not issued a ruling. 

During  the  third  quarter  of  2010,  CBP  notified  the  Railroad  of  additional  penalties  for  drug  discoveries.  
Since  then,  the  Railroad  received  additional  penalties  for  other  drug  discoveries.    The  total  outstanding 
penalty  amount  as  of  December  31,  2010,  was  approximately  $376  million.    Because  the  Railroad 
believes  that  CBP  lacks  statutory  authority  to  issue  these  fines,  the  Railroad  will  vigorously  defend 
against  these  penalties.    The  Railroad  also  is  participating  in  high-level  discussions  with  the 
Commissioner  of  CBP  to  address  the  fines  and  seizures.    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.   

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

We received additional complaints following the initial claim, increasing the total number of complaints to 
30.  In addition to suits filed by direct purchasers of rail transportation, a few of the suits involve plaintiffs 
alleging that they are or were indirect purchasers of rail transportation and seek to represent a purported 
class  of  indirect  purchasers  of  rail  transportation  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.  Subsequently,  the  direct  purchaser  plaintiffs  and  the  indirect  purchaser  plaintiffs  filed 
Consolidated Amended Class Action Complaints against UPRR and three other Class I railroads. 

One  additional  shipper  filed  a  separate  antitrust  suit  during  2008.  Subsequently,  the  shipper  voluntarily 
dismissed the action without prejudice. 

On  October  10,  2008,  Judge  Friedman  heard  oral  arguments  with  respect  to  the  defendant  railroads’ 
motions to dismiss.  In a ruling on November 7, 2008, Judge Friedman denied the motion with respect to 
the direct purchasers’ complaint, and pretrial proceedings are underway in that case.  On December 31, 
2008,  Judge  Friedman  ruled  that  the  allegations  of  the  indirect  purchasers  based  upon  state  antitrust, 
consumer  protection,  and  unjust  enrichment  laws  must  be  dismissed.    He  also  ruled,  however,  that  the 
plaintiffs  could  proceed  with  their  claim  for  injunctive  relief  under  the  federal  antitrust  laws,  which  is 
identical to a claim by the direct purchaser plaintiffs.   

The indirect purchasers appealed Judge Friedman's ruling to the U.S. Court of Appeals for the District of 
Columbia.    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.    On  June  8, 
2010, the court rejected the indirect purchasers’ requests for a rehearing of their appeal and a hearing en 
banc  by  the  entire  court.    On  September  8,  2010,  the  indirect  purchaser  plaintiffs  filed  a  Petition  for 
Certiorari  with  the  U.S.  Supreme  Court.    The  railroad  defendants  filed  their  response  on  November  9, 
2010,  urging  the  Court  not  to  review  the  lower  courts'  decisions.    On  December  13,  2010,  the  U.S. 
Supreme Court denied the indirect purchaser plaintiffs’ Petition for Certiorari. 

The  direct  purchaser  plaintiffs  filed  their  motion  for  class  certification  on  March  18,  2010.    The  railroad 
defendants filed their opposition to this motion on July 1, 2010.  Judge Friedman conducted a hearing on 
October 6 and 7, 2010, on the class certification issue and has yet to issue a decision. 

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.

At January 28, 2011, there were 491,001,416 shares of outstanding common stock and 33,537 common 
shareholders  of  record.  On  that  date,  the  closing  price  of  the  common  stock  on  the  NYSE  was  $93.54. 
Through  December  31,  2010,  we  have  paid  dividends  to  our  common  shareholders  during  each  of  the 
past 111 years.  We declared dividends totaling $653 million in 2010 and $544 million in 2009. On May 6, 
2010,  we  increased  the  quarterly  dividend  to  $0.33  per  share,  payable  beginning  on  July  1,  2010,  to 
shareholders of record on May 28, 2010.  On November 18, 2010, we increased the quarterly dividend for 
a  second  time  to  $0.38  per  share,  payable  beginning  January  3,  2011  to  shareholders  of  record  on 
November 30, 2010. We are subject to certain restrictions regarding retained earnings with respect to the 
payment of cash dividends to our shareholders. The amount of retained earnings available for dividends 
increased  to  $12.9  billion  at  December  31,  2010,  from  $11.6  billion  at  December  31,  2009.    (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  2011 
comparable to 2010.

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

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

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

EXECUTIVE SUMMARY  

2010 Results 

•  Safety  –  During  2010,  we  continued  our  positive,  multi-year  trend  in  safety  performance  by  setting 
records  in  many  of  our  safety  metrics.  The  employee  injury  incident  rate  per  200,000  man-hours 
declined 4% from 2009 to its lowest level ever. Our continued focus on derailment prevention resulted 
in  another  strong  performance  as  our  incident  rate  finished  at  10.54  per  million  train  miles,  slightly 
behind 2009 record results.  However, the severity of those incidents was lower, resulting in a 12% 
reduction in associated costs.  With respect to public safety, we closed 286 grade crossings to reduce 
our  exposure  to  incidents.  We  also  continued  installing  video  cameras  on  our  locomotives,  which 
assist  us  in  reviewing  grade  crossing  incidents,  and  we  now  have  camera-equipped  locomotives  in 
the lead position of over 97% of our through-freight trains.  During 2010, the rate of grade crossing 
incidents per million train miles increased 10% from record low levels of 2009, as both highway and 
rail  traffic  increased  in  conjunction  with  economic  improvement.    Overall,  our  2010  safety  results 
reflect our continued focus on the safety of our employees and the public.   

•  Financial  Performance  –  In  2010,  we  generated  record  operating  income  of  $5.0  billion,  a  47% 
increase  over  2009,  reflecting  a  13%  increase  in  volume,  core  pricing  gains,  and  improved 
productivity.    Improved  economic  conditions  increased  demand  for  our  services  across  almost  all 
market  sectors  compared  to  2009,  a  year  in  which  economic  conditions  substantially  reduced 
demand for rail service.  We leveraged additional traffic volumes during 2010 by effectively utilizing 
our  assets  and  minimizing  operational  cost  increases  compared  to  2009.    These  achievements 
translated into an all-time record operating ratio of 70.6% for 2010, outpacing our previous record of 
76.1%  set  in  2009.    Net  income  of  $2.8  billion  also  surpassed  our  previous  milestone  set  in  2008, 
translating into earnings of $5.53 per diluted share for 2010. 

•  Freight Revenues – Our freight revenues grew 20% year-over-year to $16.1 billion. Freight revenues 
and volumes for all six commodity groups increased.   Overall, volume increased 13% in 2010, with 
particularly strong growth in automotive, intermodal, and industrial products shipments.  Core pricing 
gains and higher fuel surcharges (due to higher fuel prices, volume growth, and new fuel surcharge 
provisions  in  contracts  renegotiated  in  2010)  also  drove  the  growth  in  freight  revenue  in  2010 
compared  to  2009.    We  continued  to  focus  on  improving  the  reinvestibility  of  our  business,  and  we 
have repriced approximately 88% of our business since 2004.  

•  Network  Operations  –  In  2010,  we  continued  operating  an  efficient  and  fluid  network,  effectively 
handling  the  13%  increase  in  carloads  compared  to  2009.    As  reported  to  the  Association  of 
American Railroads (AAR), average train speed decreased 4% in 2010 compared to a record-setting 
2009.    Maintenance  activities  and  weather  disruptions,  combined  with  higher  volume  levels, 
negatively  impacted  our  average  train  speed.    Average  terminal  dwell  time  increased  2%  while 
average  rail  car  inventory  decreased  3%  in  2010  compared  to  2009.    We  maintained  more  freight 
cars  off-line  and  retired  a  number  of  old  freight  cars,  which  drove  a  decrease  in  average  rail  car 
inventory during the year.  In 2010, customer satisfaction improved, surpassing a record established 
in  2009,  an  indication  that  our  ongoing  efforts  to  improve  operations  again  translated  into  better 
customer service.  

•  Asset Utilization – In response to economic conditions and lower revenue in 2009, we implemented 
productivity initiatives to improve efficiency and reduce costs, in addition to adjusting our resources to 
reflect lower demand.  By the end of 2009, we had removed from service approximately 26% of our 
multiple purpose locomotives and 18% of our freight car inventory.  As volume increased 13% from 

23 

 
 
 
 
 
 
 
 
 
 
2009 levels, we returned a portion of these assets to active service.  At the end of 2010, we continued 
to maintain in storage approximately 17% of our multiple purpose locomotives and 14% of our freight 
car inventory, reflecting our ability to effectively leverage our assets as volumes return to our network. 

•  Fuel  Prices  –  Fuel  prices  generally  increased  throughout  2010  as  the  economy  improved.    Our 
average diesel fuel price per gallon increased nearly 20% from January to December of 2010, driven 
by higher crude oil barrel prices and conversion spreads.  Compared to 2009, our diesel fuel price per 
gallon  consumed  increased  31%,  driving  operating  expenses  up  by  $566  million  (excluding  any 
impact from year-over-year volume increases). To partially offset the effect of higher fuel prices, we 
reduced our consumption rate by 3% during the year, saving approximately 27 million gallons of fuel. 
The use of newer, more fuel efficient locomotives; increased use of distributed locomotive power (the 
practice  of  distributing  locomotives  throughout  a  train  rather  than  positioning  them  all  in  the  lead 
resulting  in  safer  and  more  efficient  train  operations);  fuel  conservation  programs;  and  efficient 
network operations and asset utilization all contributed to this improvement.  

•  Free  Cash  Flow  –  Cash  generated  by  operating  activities  (adjusted  for  the  reclassification  of  our 
receivables securitization facility) totaled $4.5 billion, yielding record free cash flow of $1.4 billion in 
2010.    Free  cash  flow  is  defined  as  cash  provided  by  operating  activities  (adjusted  for  the 
reclassification  of  our  receivables  securitization  facility),  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. We believe free cash 
flow  is  important  in  evaluating  our  financial  performance  and  measures  our  ability  to  generate  cash 
without additional external financings. Free cash flow should be considered in addition to, rather than 
as a substitute for, cash provided by operating activities. The following table reconciles cash provided 
by operating activities (GAAP measure) to free cash flow (non-GAAP measure):

[a]  Effective  January  1,  2010,  a  new  accounting  standard  required  us  to  account  for  receivables  transferred  under  our
receivables  securitization  facility  as  secured  borrowings  in  our  Consolidated  Statements  of  Financial  Position  and  as
financing activities in our Consolidated Statements of Cash Flows.  The receivables securitization facility is included in our 
free  cash  flow  calculation  to  adjust  cash  provided  by  operating  activities  as  though  our  receivables  securitization  facility 
had been accounted for under the new accounting standard for all periods presented.   

2011 Outlook 

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

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

24 

 
 
 
 
 
  
  
  
  
  
  
  
  
  
  
 
 
 
us  in  a  position  to  handle  demand  changes.  We  will  also  continue  utilizing  industrial  engineering 
techniques to improve productivity. 

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

•  Capital  Plan  –  In  2011,  we  plan  to  make  total  capital  investments  of  approximately  $3.2  billion, 
including expenditures for Positive Train Control (PTC), which 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.) 

•  Positive Train Control – In response to a legislative mandate to implement PTC by the end of 2015, 
we  expect  to  spend  approximately  $250  million  during  2011  on  developing  PTC.    We  currently 
estimate  that  PTC  will  cost  us  approximately  $1.4  billion  to  implement  by  the  end  of  2015,  in 
accordance with rules issued by the Federal Railroad Administration (FRA).  This includes costs for 
installing the new system along our tracks, upgrading locomotives to work with the new system, and 
adding  digital  data  communication  equipment  so  all  the  parts  of  the  system  can  communicate  with 
each other.  During 2011, we plan to begin testing the technology to evaluate its effectiveness.   

•  Financial Expectations – We remain cautious about economic conditions, but anticipate volume to 
increase  from  2010  levels.    In  addition,  we  expect  volume,  price,  and  productivity  gains  to  offset 
expected higher costs for fuel, labor inflation, depreciation, casualty costs, and property taxes to drive 
operating ratio improvement.

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

Other  revenues  include  revenues  earned  by  our  subsidiaries,  revenues  from  our  commuter  rail 
operations,  and  accessorial  revenues,  which  we  earn  when  customers  retain  equipment  owned  or 
controlled by us or when we perform additional services such as switching or storage. We recognize other 
revenues as we perform services or meet contractual obligations. 

Freight  revenues  and  volume  levels  for  all  six  commodity  groups  increased  during  2010  as  a  result  of 
economic  improvement  in  many  market  sectors.    We  experienced  particularly  strong  volume  growth  in 
automotive, intermodal, and industrial products shipments. Core pricing gains and higher fuel surcharges 
also increased freight revenues and drove a 6% improvement in ARC.  

Freight  revenues  and  volume  levels  for  all  six  commodity  groups  decreased  during  2009,  reflecting 
continued economic weakness. We experienced the largest volume declines in automotive and industrial

products  shipments.    Lower  fuel  surcharges  due  to  lower  fuel  prices  also  reduced  freight  revenues  in 
2009 compared to 2008.  ARC decreased 7% during the  full year, driven by lower fuel cost recoveries, 
partially  offset  by  core  pricing  gains  of  approximately  5%.    Fuel  cost  recoveries  include  fuel  surcharge 
revenue  and  the  impact  of  resetting  the  base  fuel  price  for  certain  traffic,  which  is  described  below  in 
more detail.  

Our fuel surcharge programs (excluding index-based contract escalators that contain some provision for 
fuel)  generated  freight  revenues  of  $1.2  billion,  $605  million,  and  $2.3  billion  in  2010,  2009,  and  2008, 
respectively.    Higher  fuel  prices,  volume  growth,  and  new  fuel  surcharge  provisions  in  contracts 
renegotiated during the year increased fuel surcharge amounts in 2010.  Furthermore, for certain periods 
during  2009,  fuel  prices  dropped  below  the  base  at  which  our  mileage-based  fuel  surcharge  begins, 
which resulted in no fuel surcharge recovery for associated shipments during those periods.   

Fuel surcharge revenue is not entirely comparable to prior periods due to implementation of new mileage-
based  fuel  surcharge  programs.    In  April  2007,  we  converted  regulated  traffic,  which  represents 
approximately 20% of our current revenue base, to mileage-based fuel surcharge programs.  In addition, 
we  have  converted  and  continue  to  convert  portions  of  our  non-regulated  traffic  to  mileage-based  fuel 
surcharge programs. At the time of conversion, we reset the base fuel price at which the new mileage-
based  fuel  surcharges  take  effect.  Resetting  the  fuel  price  at  which  the  fuel  surcharge  begins,  in 
conjunction  with  rebasing  the  affected  transportation  rates  to  include  a  portion  of  what  had  been  in  the 
fuel  surcharge,  does  not  materially  change  our  freight  revenue  as  higher  base  rates  offset  lower  fuel 
surcharge revenue.   

In  2010,  other  revenues  increased  from  2009  due  primarily  to  higher  revenues  at  our  subsidiaries  that 
broker  intermodal  and  automotive  services.    Assessorial  revenues  also  increased  in  2010  reflecting 
higher volume levels during the year.   

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

The following tables summarize the year-over-year changes in freight revenues, revenue carloads (each 
container or trailer is counted as one carload), and ARC by commodity type:

Agricultural  Products  –  Higher  volume,

agricultural  freight  revenue  in  2010  versus  2009.  
Increased  shipments  from  the  Midwest  to  export 
the  Pacific  Northwest  combined  with 
ports 
heightened  demand  in  Mexico  drove  higher  corn 
and  feed  grain  shipments  in  2010.    Increased  corn 
and  feed  grain  shipments  into  ethanol  plants  in 
California  and  Idaho  and  continued  growth  in 
ethanol shipments also contributed to this increase. 
In  2009,  some  ethanol  plants  temporarily  ceased 
operations  due  to  lower  ethanol  margins,  which 
contributed 
year-over-year 
comparison.    In  addition,  strong  export  demand  for 
U.S.  wheat  via  the  Gulf  ports  increased  shipments 
of  wheat  and  food  grains  compared  to  2009.    Declines  in  domestic  wheat  and  food  shipments  partially 
offset the growth in export shipments.  New business in feed and animal protein shipments also increased 
agricultural shipments in 2010 compared to 2009.

the 

to 

Lower  volume  and  fuel  surcharges  decreased  agricultural  freight  revenue  in  2009  versus  2008.  Price 
improvements partially offset these declines. Lower demand in both export and domestic markets led to 
fewer  shipments  of  corn  and  feed  grains,  down  11%  in  2009  compared  to  2008.  Weaker  worldwide 
demand also reduced export shipments of wheat and food grains in 2009 versus 2008.   

Automotive – 37% and 24% increases in shipments 
of  finished  vehicles  and  automotive  parts  in  2010, 
respectively,  combined  with  core  pricing  gains  and 
fuel  surcharges, 
freight 
revenue from relatively weak 2009 levels. Economic 
conditions  in  2009  led  to  poor  auto  sales  and 
reduced  vehicle  production,  which  in  turn  reduced 
shipments  of  finished  vehicles  and  parts  during  the 
year.

2010 Automotive Revenue 

in  2009  compared 

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

modest  rebound  in  market  conditions  and  more 
normalized  inventory  levels  increased  demand  for 
industrial chemicals during the year, driving volume 
levels up 8% versus 2009.  In addition, shipments of 
soda ash increased 12% as continued strong export 
demand outpaced weak 2009 export demand. 

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

2010 Energy Revenue 

Energy – Core pricing gains, higher fuel surcharges 
and  modest  volume  growth 
freight 
revenue  from  energy  shipments  in  2010  compared 
to  2009.    Shipments  from  the  Southern  Powder 
River  Basin  (SPRB)  were  up  4%  driven  by  higher 
demand  resulting  from  improvement  in  economic 
conditions,  warmer  summer  weather,  and  more 
efficient  deliveries 
tons  per  car  and 
(higher 
increased  train  size).    Higher  inventory  levels 
carried  over  from  2009  partially  offset  this  demand 
increase.    Shipments  from  Colorado  and  Utah 
mines  were  down  8%  in  2010  versus  2009  due  to 
increased 
mine  production 
competition from other low cost fuel options (natural 
gas and eastern coal), weaker demand from our industrial customers, and high inventories at some utility 
customer locations.  

interruptions  and 

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

       2010 Industrial Products Revenue 

fuel 

Industrial  Products  –  Volume  gains,  core  pricing 
improvement,  and  higher 
surcharges 
increased freight revenue from industrial products 
in  2010  versus  2009.    A  federal  government 
remediation program involving removal of uranium 
mill  tailings  from  a  Moab,  Utah,  site  drove  an 
increase in short-haul hazardous waste shipments 
versus  2009.    Shipments  under  this  program 
began  modestly  during  the  second  quarter  of 
2009.    Steel  shipments  also  increased  due  to 
improving  economic  conditions,  while  shipments 
of non-metallic minerals (primarily frac sand) grew 
in  response  to  more  drilling  for  natural  gas.  
Stone,  sand  and  gravel  shipments  grew  in  2010 
compared  to  2009  as  increased  oil  drilling  more 
than offset the decline in commercial construction 
activity. 

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

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

Mexico Business – Each of our commodity groups include revenue from shipments to and from Mexico. 
Revenue from Mexico business increased 30% in 2010 versus 2009 to $1.6 billion. Volume levels for all 
six  commodity  groups  increased,  up  25%  in  aggregate  versus  2009,  with  particularly  strong  growth  in 
automotive, industrial products, and intermodal shipments. 

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

Operating expenses increased $1.2 billion in 2010 
versus 2009.  Our fuel price per gallon increased 
31%  during  the  year,  accounting  for  $566  million 
of  the  increase.    Wage  and  benefit  inflation, 
depreciation,  volume-related  costs,  and  property 
taxes  also  contributed  to  higher  expenses  during 
2010  compared  to  2009.  Cost  savings  from 
productivity  improvements  and  better  resource 
utilization partially offset these increases.   

        2010 Operating Expenses 

Operating  expenses  decreased  $3.1  billion  in 
2009  versus  2008.    Our  fuel  price  per  gallon 
declined  44%  during  2009,  decreasing  operating 
expenses by $1.3 billion compared to 2008.  Cost 
savings 
productivity 
improvements, and better resource utilization also

In 
addition,  lower  casualty  expense  resulting  primarily  from  improving  trends  in  safety  performance

Compensation  and  Benefits  –  Compensation  and  benefits  include  wages,  payroll  taxes,  health  and 
welfare  costs,  pension  costs,  other  postretirement  benefits,  and  incentive  costs.  General  wage  and 
benefit  inflation  increased  costs  by  approximately  $190  million  in  2010  compared  to  2009.    Volume-
related  expenses  and  higher  equity  and  incentive  compensation  also  drove  costs  up  during  the  year.  
Workforce levels declined 1% in 2010 compared to 2009 as network efficiencies and ongoing productivity 
initiatives enabled us to effectively handle the 13% increase in volume levels with fewer employees. 

Lower volume and productivity initiatives led to a 10% decline in our workforce in 2009 compared to 2008, 
saving $516 million during the year.  Conversely, general wage and benefit inflation increased expenses, 
partially offsetting these savings. 

Fuel  –  Fuel  includes  locomotive  fuel  and  gasoline  for  highway  and  non-highway  vehicles  and  heavy 
equipment.  Higher diesel fuel prices, which averaged $2.29 per gallon (including taxes and transportation 
costs) in 2010 compared to $1.75 per gallon in 2009, increased expenses by $566 million.  Volume, as 
measured  by  gross  ton-miles,  increased  10%  in  2010  versus  2009,  driving  fuel  expense  up  by  $166 
million.    Conversely,  the  use  of  newer,  more  fuel  efficient  locomotives,  our  fuel  conservation  programs 
and efficient network operations drove a 3% improvement in our fuel consumption rate in 2010, resulting 
in $40 million of cost savings versus 2009 at the 2009 average fuel price.  

Lower  diesel  fuel  prices,  which  averaged  $1.75  per  gallon  (including  taxes  and  transportation  costs)  in 
2009  compared  to  $3.15  per  gallon  in  2008,  reduced  expenses  by  $1.3  billion  in  2009.    Volume,  as 
measured by gross ton-miles, decreased 17% in 2009, lowering expenses by $664 million compared to 
2008.  Our fuel consumption rate improved 4% in 2009, resulting in $147 million of cost savings versus 
2008 at the 2008 average fuel price. The consumption rate savings versus 2008 using the lower 2009 fuel 
price was $68 million. Newer, more fuel efficient locomotives, reflecting locomotive acquisitions in recent 
years and the impact of a smaller fleet due to storage of some of our older locomotives; increased use of 

30 

 
 
 
 
 
 
 
 
 
 
 
distributed locomotive power; our fuel conservation programs; and improved network operations all drove 
this improvement. 

Purchased  Services  and  Materials  –  Purchased  services  and  materials  expense  includes  the  costs  of 
services  purchased  from  outside  contractors  (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.  A $148 million increase in 
expenses for contract services drove the higher expenses in 2010 versus 2009.  Volume-related trucking 
and  lift  costs  for  intermodal  containers  and  crew  transportation  and  lodging  costs  also  increased  costs 
from 2009.  In addition, an increase in locomotive maintenance materials used to prepare a portion of our 
locomotive  fleet  for  return  to  active  service  increased  expenses  during  the  year  compared  to  2009.  
Conversely,  a  decrease  in  freight  car  maintenance  activity  during  2010  drove  lower  freight  car  material 
costs, partially offsetting the cost increases versus 2009.   

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

Depreciation – The majority of depreciation relates to road property, including rail, ties, ballast, and other 
track  material.  A  higher  depreciable  asset  base,  reflecting  higher  capital  spending  in  recent  years, 
increased depreciation expense in 2010 compared to 2009. Costs also increased $25 million in 2010 due 
to the restructuring of certain locomotive leases in the second quarter of 2009.  Lower depreciation rates 
for  rail  and  other  track  material  partially  offset  the  increases.  The  lower  rates,  which  became  effective 
January 1, 2010, resulted from reduced track usage (based on lower gross ton-miles in 2009). 

A  higher  depreciable  asset  base,  reflecting  higher  capital  spending  in  recent  years,  increased 
depreciation  expense  in  2009  versus  2008.    Costs  also  increased  $34  million  in  2009  due  to  the 
restructuring  of  certain  locomotive  leases.    Lower  depreciation  rates  for  rail  and  other  track  material 
partially  offset  the  increases.    The  lower  rates,  which  became  effective  January  1,  2009,  resulted  from 
longer asset lives as determined by service life studies and reduced track usage (based on lower gross 
ton-miles in 2008). 

Equipment and Other Rents – Equipment and other rents expense primarily includes rental expense that 
the Railroad pays for freight cars owned by other railroads or private companies; freight car, intermodal, 
and locomotive leases; other specialty equipment leases; and office and other rentals.  Short-term freight 
car  rental  expense  increased  in  2010  compared  to  2009,  reflecting  increased  shipments  of  finished 
vehicles  and  intermodal  containers.    Increased  lease  expenses  for  containers  also  drove  the  increase.  
Conversely,  lower  lease  expense  for  freight  cars  and  locomotives  decreased  costs  compared  to  2009. 
The  restructuring  of  locomotive  leases  (completed  in  May  2009)  also  reduced  lease  expense  by  $36 
million  in  2010  compared  to  2009.    (See  further  discussion  in  this  Item  7  under  Liquidity  and  Capital 
Resources – Financing Activities.)   

Fewer shipments of industrial products and intermodal containers primarily contributed to the $85 million 
reduction in our short-term freight car rental expense in 2009 versus 2008.  In addition, the restructuring 
of  locomotive  leases  reduced  lease  expense  by  $52  million  in  2009  compared  to  2008.    Lower  lease 
expense  for  freight  cars,  intermodal  containers,  and  fleet  vehicles  also  decreased  costs  in  2009  versus 
2008.   

Other  –  Other  expenses  include  personal  injury,  freight  and  property  damage,  destruction  of  foreign 
equipment,  insurance,  environmental,  bad  debt,  state  and  local  taxes,  utilities,  telephone  and  cellular, 
employee  travel,  computer  software,  and  other  general  expenses.  Other  costs  were  higher  in  2010 
compared  to  2009,  driven  by  higher  property  taxes  and  the  $45  million  one-time  payment  in  the  first 
quarter of 2010 related to a transaction with CSXI.  A $30 million payment in 2009 to Pacer International, 

31 

 
 
 
 
 
 
 
 
Inc.  and  lower  expenses  for  freight  and  property  damages  partially  offset  these  increases  in  comparing 
2009  with  2010.    In  addition,  personal  injury  expense  was  lower  in  2010  compared  to  2009,  reflecting 
continued  improvement  in  our  personal  injury  incident  rate  and  lower  settlement  costs  per  claim.    The 
change  in  asbestos-related  claim  expenses  in  2010  versus  2009  offset  the  lower  personal  injury  costs.  
As  a  result  of  our  2009  annual  review  of  asbestos-related  costs,  we  reduced  expenses  by  $25  million, 
thus driving the unfavorable variance in 2010.   

Other costs were lower in 2009 compared to 2008, driven by a reduction in personal injury expense and 
asbestos-related claims expense.  We completed actuarial studies of personal injury expenses in both the 
second  and  fourth  quarters  of  2009  and  2008  and  annual  reviews  of  asbestos-related  claims  in  both 
years,  which  resulted  in  a  net  reduction  of  $55  million  in  casualty  expense  in  2009  versus  2008.  The 
reduction reflects improvements in our safety experience and lower estimated costs to resolve claims.  In 
addition,  the  year-over-year  comparison  was  favorably  impacted  by  $28  million  due  to  an  adverse 
development with respect to one personal injury claim in 2008 and favorable developments in three cases 
in 2009.  Other costs were also lower in 2009 compared to 2008, driven by a decrease in expenses for 
freight and property damages, employee travel, and utilities. In addition, higher bad debt expense in 2008 
due to the uncertain impact of the recessionary economy drove a favorable year-over-year comparison.  
Conversely, an additional expense of $30 million related to a transaction with Pacer International, Inc. and 
higher property taxes partially offset lower costs in 2009.

Other Income – Other income decreased in 2010 versus 2009 due to lower gains from real estate sales 
(the  second  quarter  of  2009  included  a  $116  million  pre-tax  gain  from  a  land  sale  to  the  Regional 
Transportation District in Colorado) and premiums paid for early debt redemption. 

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

Interest  Expense  –  Interest  expense  was  flat  in  2010  compared  to  2009  due  to  a  modestly  higher 
weighted-average debt level of $9.7 billion, compared to $9.6 billion in 2009, offset by a lower effective 
interest rate of 6.2% in 2010, compared to 6.3% in 2009. 

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

Income Taxes – Income taxes were higher in 2010 compared to 2009, primarily driven by higher pre-tax 
income. Our effective tax rate for the year was 37.3% compared to 36.4% in 2009.  Income taxes were 
lower  in  2009  compared  to  2008,  driven  by  lower  pre-tax  income.  Our  effective  tax  rate  for  2009  was 
36.4% compared to 36.0% in 2008.

Average Train Speed – Average train speed is calculated by dividing train miles by hours operated on our 
main  lines  between  terminals.  Maintenance  activities  and  weather  disruptions,  combined  with  higher 
volume levels, led to a 4% decrease in average train speed in 2010 compared to a record set in 2009.  
Overall,  we  continued  operating  a  fluid  and  efficient  network  during  the  year.    Lower  volume  levels, 
ongoing  network  management  initiatives,  and  productivity  improvements  contributed  to  a  16% 
improvement in average train speed in 2009 compared to 2008.   

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  2%  in  2010  compared  to  2009,  driven  in  part  by  our  network  plan  to  increase  the 
length  of  numerous  trains  to  improve  overall  efficiency,  which  resulted  in  higher  terminal  dwell  time  for 
some cars.  Average terminal dwell time improved slightly in 2009 compared to 2008 due to lower volume 
levels combined with initiatives to expedite delivering rail cars to our interchange partners and customers.  

Average  Rail  Car  Inventory  – Average rail car inventory is the daily  average  number  of  rail  cars  on  our 
lines, including rail cars in storage. Lower average rail car inventory reduces congestion in our yards and 
sidings,  which  increases  train  speed,  reduces  average  terminal  dwell  time,  and  improves  rail  car 
utilization.  Average  rail  car  inventory  decreased  3%  in  2010  compared  to  2009,  while  we  handled  13% 
increases in carloads during the period compared to 2009.  We maintained more freight cars off-line and 
retired a number of old freight cars, which drove the decreases.  Average rail car inventory decreased 6% 
in 2009 compared to 2008 driven by a 16% decrease in volume.  In addition, as carloads decreased, we 
stored more freight cars off-line.   

Gross and Revenue Ton-Miles – Gross ton-miles are calculated by multiplying the weight of loaded and 
empty  freight  cars  by  the  number  of  miles  hauled.  Revenue  ton-miles  are  calculated  by  multiplying  the 
weight  of  freight  by  the  number  of  tariff  miles.  Gross  and  revenue-ton-miles  increased  10%  and  9%  in 
2010 compared to 2009 due to a 13% increase in carloads.  Commodity mix changes (notably automotive 
shipments) drove the variance in year-over-year growth between gross ton-miles, revenue ton-miles and 
carloads.    Gross  and  revenue  ton-miles  decreased  17%  and  15%  in  2009  compared  to  2008  due  to  a 
16%  decrease  in  carloads.    Commodity  mix  changes  (notably  automotive  shipments,  which  were  30% 
lower  in  2009  versus  2008)  drove  the  difference  in  declines  between  gross  ton-miles  and  revenue  ton-
miles.  

Operating  Ratio  –  Operating  ratio  is  defined  as  our  operating  expenses  as  a  percentage  of  operating 
revenue.  Our  operating  ratio  improved  5.5  points  to  70.6%  in  2010  and  1.3  points  to  76.1%  in  2009.  
Efficiently  leveraging  volume  increases,  core  pricing  gains,  and  productivity  initiatives  drove  the 
improvement in 2010 and more than offset the impact of higher fuel prices during the year.  Core pricing 
gains,  lower  fuel  prices,  network  management  initiatives,  and  improved  productivity  drove  the 
improvement in 2009 and more than offset the 16% volume decline. 

Employees  –  Employee  levels  were  down  1%  in  2010  compared  to  2009  despite  a  13%  increase  in 
volume levels.  We leveraged the additional volumes through network efficiencies and other productivity 
initiatives.    In  addition,  we  successfully  managed  the  growth  of  our  full-time-equivalent  train  and  engine 
force  levels  at  a  rate  less  than  half  of  our  carload  growth  in  2010.    All  other  operating  functions  and

ROIC is considered a non-GAAP financial measure by SEC Regulation G and Item 10 of SEC Regulation 
S-K,  and  may  not  be  defined  and  calculated  by  other  companies  in  the  same  manner.  We  believe  this 
measure is important in evaluating the efficiency and effectiveness of the Corporation’s long-term capital 
investments.    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 2010 ROIC improved 
2.6 points compared to 2009, primarily as a result of higher earnings.

Adjusted debt to capital is a non-GAAP financial measure under SEC Regulation G and Item 10 of SEC 
Regulation  S-K.  We  believe  this  measure  is  important  to  management  and  investors  in  evaluating  the 
total amount of leverage in our capital structure, including off-balance sheet lease obligations, which we 
generally  incur  in  connection  with  financing  the  acquisition  of  locomotives  and  freight  cars  and  certain 
facilities.    Effective  January  1,  2010,  the  value  of  the  outstanding  undivided  interest  held  by  investors 
under our receivables securitization facility is included in our Consolidated Statement of Financial Position 
as  debt  due  after  one  year.    At  December  31,  2010,  that  amount  was  $100  million.    Operating  leases 
were discounted using 6.2% at December 31, 2010 and 6.3% at December 31, 2009. The lower discount 
rate  reflects  changes  to  interest  rates  and  our  current  financing  costs.  We  monitor  the  ratio  of  adjusted 
debt  to  capital  as  we  manage  our  capital  structure  to  balance  cost-effective  and  efficient  access  to  the 
capital  markets  with  the  Corporation’s  overall  cost  of  capital.  Adjusted  debt  to  capital  should  be 
considered  in  addition  to,  rather  than  as  a  substitute  for,  debt  to  capital.  The  tables  above  provide 
reconciliations  from  debt  to  capital  to  adjusted  debt  to  capital.  Our  December  31,  2010  debt  to  capital 
ratios  decreased  as  a  result  of  a  $606  million  net  decrease  in  debt  from  December  31,  2009.  Debt, 
including  the  value  of  our  receivables  securitization  facility,  decreased  $1.0  billion  from  December  31, 
2009.   

LIQUIDITY AND CAPITAL RESOURCES 

As  of  December  31,  2010,  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 (such as the remaining authority under 
our shelf registration). We had $1.9 billion of committed credit available under our credit facility, with no 
borrowings  outstanding  as  of  December  31,  2010.  We  did  not  make  any  borrowings  under  this  facility 
during  2010.  The  value  of  the  outstanding  undivided  interest  held  by  investors  under  the  receivables 
securitization  facility  was  $100  million  as  of  December  31,  2010,  and  is  included  in  our  Consolidated 
Statements  of  Financial  Position  as  debt  due  after  one  year.    The  receivables  securitization  facility  is 
subject  to  certain  requirements,  including  maintenance  of  an  investment  grade  bond  rating.  If  our  bond 
rating were to deteriorate, it could have an adverse impact on our liquidity. Access to commercial paper 
as  well  as  other  capital  market  financings  is  dependent  on  market  conditions.  Deterioration  of  our 
operating  results  or  financial  condition  due  to  internal  or  external  factors  could  negatively  impact  our 
ability to 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  by 
issuing bonds to public or private investors based on our assessment of the current condition of the credit 
markets. 

At  December  31,  2010  and  2009,  we  had  a  working  capital  surplus,  which  in  2010  continues  to  be  the 
result  of  our  decision  in  2009  to  maintain  additional  cash  reserves  to  enhance  liquidity  in  response  to 

35 

 
 
 
  
  
 
 
 
 
uncertain economic conditions. Historically, we have had a working capital deficit, which is common in our 
industry and does not indicate a lack of liquidity. We maintain adequate resources and, when necessary, 
have  access  to  capital  to  meet  any  daily  and  short-term  cash  requirements,  and  we  have  sufficient 
financial capacity to satisfy our current liabilities.

Higher  net  income  in  2010  increased  cash  provided  by  operating  activities  compared  to  2009.  
Conversely,  the  adoption  of  a  new  accounting  standard  for  our  receivables  securitization  facility  from  a 
sale  of  undivided  interests  (recorded  as  an  operating  activity)  to  a  secured  borrowing  (recorded  as  a 
financing  activity)  decreased  cash  provided  by  operating  activities  by  $400  million  in  2010  versus  $184 
million in 2009.  Lower net income in 2009, a reduction of $184 million in the outstanding balance of our 
receivables  securitization  facility,  higher  pension  contributions  of  $72  million,  and  changes  to  working 
capital combined to decrease cash provided by operating activities compared to 2008. 

Investing Activities 

Higher capital investments and lower proceeds from asset sales in 2010 drove the increase in cash used 
in investing activities compared to 2009.  Lower capital investments and higher proceeds from asset sales 
drove the decrease in cash used in investing activities in 2009 versus 2008.

Capital  Plan  –  In  2011,  we  expect  our  total  capital  investments  to  be  approximately  $3.2  billion,  which 
may be revised if business conditions warrant or if new laws or regulations affect our ability to generate 
sufficient  returns  on  these  investments.  We  expect  that  approximately  65%  of  our  2011  capital 

36 

 
 
  
  
  
 
 
 
 
 
 
 
  
 
investments  will  replace  and  improve  existing  capital  assets.  Major  investment  categories  include 
replacing  and  improving  track  infrastructure;  increasing  network  and  terminal  capacity;  upgrading  our 
locomotive,  freight  car  and  container  fleet,  including  acquiring  100  locomotives,  600  covered  hoppers, 
4,800 containers and 4,800 chassis; improving technology, including investing in PTC; and other capital 
projects. We expect to fund our 2011 cash capital investments through cash generated from operations, 
the sale or lease of various operating and non-operating properties, issuance of long-term debt, and cash 
on hand at December 31, 2010. Our annual capital plan is a critical component of our long-term strategic 
plan,  which  we  expect  will  enhance  the  long-term  value  of  the  Corporation  for  our  shareholders  by 
providing  sufficient  resources  to  (i)  replace  and  improve  our  existing  track  infrastructure  to  provide  safe 
and  fluid  operations,  (ii)  increase  network  efficiency  by  adding  or  improving  facilities  and  track,  and  (iii) 
make investments that meet customer demand and take advantage of opportunities for long-term growth. 

Financing Activities 

Cash  used  in  financing  activities  increased  in  2010  versus  2009.  During  2010,  we  repurchased  $1.2 
billion  of  shares  under  our  common  stock  repurchase  program,  compared  to  no  repurchases  in  2009.  
Additionally, our net debt reduction in 2010 was $518 million compared to $28 million in 2009, which also 
contributed to the increase in cash used in financing activities in 2010.  Cash used in financing activities 
decreased  in  2009  versus  2008  driven  by  share  repurchases  totaling  $1.6  billion  in  2008.    Additionally, 
debt  repayments  were  $337  million  lower  in  2009,  partially  offset  by  lower  new  debt  issuances  of  $1.4 
billion and higher dividend payments (we increased our dividend from $0.22 per share to $0.27 per share, 
effective in the third quarter of 2008). The restructuring of equipment leases in 2009 also generated $87 
million in cash consideration, further contributing to the decrease.  

Credit  Facilities  –  On  December  31,  2010,  we  had  $1.9  billion  of  credit  available  under  our  revolving 
credit  facility  (the  facility).  The  facility  is  designated  for  general  corporate  purposes  and  supports  the 
issuance of commercial paper. We did not draw on the facility during 2010. Commitment fees and interest 
rates  payable  under  the  facility  are  similar  to  fees  and  rates  available  to  comparably  rated,  investment-
grade  borrowers.  The  facility  allows  borrowings  at  floating  rates  based  on  London  Interbank  Offered 
Rates,  plus  a  spread,  depending  upon  our  senior  unsecured  debt  ratings.  The  facility  requires  Union 
Pacific Corporation to maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing. 
At  December  31,  2010,  and  December  31,  2009  (and  at  all  times  during  these  periods),  we  were  in 
compliance with this covenant. 

The  definition  of  debt  used  for  purposes  of  calculating  the  debt-to-net-worth  coverage  ratio  includes, 
among  other  things,  certain  credit  arrangements,  capital  leases,  guarantees  and  unfunded  and  vested 
pension  benefits  under  Title  IV  of  ERISA.  At  December  31,  2010,  the  debt-to-net-worth  coverage  ratio 
allowed us to carry up to $35.5 billion of debt (as defined in the facility), and we had $9.7 billion of debt 
(as defined in the facility) outstanding at that date.  Under our current capital plans, we expect to continue 
to  satisfy  the  debt-to-net-worth  coverage  ratio;  however,  many  factors  beyond  our  reasonable  control 
(including the Risk Factors in Item 1A of this report) could affect our ability to comply with this provision in 
the  future.  The  facility  does  not  include  any  other  financial  restrictions,  credit  rating  triggers  (other  than 
rating-dependent pricing), or any other provision that could require us to post collateral. The facility also 
includes a $75 million cross-default provision and a change-of-control provision. The facility will expire in 
April 2012 in accordance with its terms, and we currently intend to replace the facility with a substantially 
similar credit agreement on or before the expiration date, which is consistent with our past practices with 
respect to our credit facilities. 

During  2010,  we  did  not  issue  or  repay  any  commercial  paper  and,  at  December  31,  2010,  we  had  no 
commercial paper outstanding.  Our commercial paper balance is supported by our revolving credit facility 
but does not reduce the amount of borrowings available under the facility.   

At December 31, 2010, we reclassified as long-term debt approximately $100 million of debt due within 
one year that we intend to refinance. This reclassification reflected our ability and intent to refinance any 
short-term borrowings and certain current maturities of long-term debt on a long-term basis. At December 
31, 2009, we reclassified as long-term debt approximately $320 million of debt due within one year that 
we intended to refinance at that time.

Ratio of Earnings to Fixed Charges 

For each of the years ended December 31, 2010, 2009, and 2008, our ratio of earnings to fixed charges 
was  6.9,  4.9,  and  5.9,  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 $12.9 billion 
and $11.6 billion at December 31, 2010 and 2009, respectively. 

Share Repurchase Program – On May 1, 2008, our Board of Directors authorized the repurchase of 40 
million common shares by March 31, 2011.  Management’s assessments of market conditions and other 
pertinent facts guide the timing and volume of all repurchases. Any share repurchases under this program 
are expected to be funded 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.

On  February  3,  2011,  our  Board  of  Directors  authorized  us  to  repurchase  up  to  40  million  additional 
shares of our common stock under a new program effective from April 1, 2011 through March 31, 2014. 

Shelf  Registration  Statement  and  Significant  New  Borrowings  –  We  filed  a  shelf  registration 
statement, which became effective upon filing on February 10, 2010. Our Board of Directors authorized 
the issuance of up to $3 billion of debt securities, replacing the $2.25 billion of authority remaining under 
our shelf registration filed in March 2007. Under the 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.  

During  2010,  we  issued  the  following  unsecured,  fixed-rate  debt  securities  under  our  current  shelf 
registration: 

 Date 
 August 2, 2010 

Description of Securities 
$500 million of 4.00% Notes due February 1, 2021 

The net proceeds from the offering were used for general corporate purposes, including the repurchase of 
common  stock  pursuant  to  our  share  repurchase  program.  These  debt  securities  include  change-of-
control provisions.  

We have no immediate plans to issue equity securities; however, we will continue to explore opportunities 
to replace existing debt or access capital through issuances of debt securities under our shelf registration, 
and,  therefore,  we  may  issue  additional  debt  securities  at  any  time.  At  December  31,  2010,  we  had 
remaining authority to issue up to $2.5 billion of debt securities under our shelf registration.

Debt Exchange – On July 14, 2010, we exchanged $376 million of 7.875% notes due in 2019 (Existing 
Notes)  for  5.78%  notes  (New  Notes)  due  July  15,  2040,  plus  cash  consideration  of  approximately  $96 
million  and  $15  million  for  accrued  and  unpaid  interest  on  the  Existing  Notes.    The  cash  consideration, 
recorded as an adjustment to the carrying value of debt, and the balance of the unamortized discount and 
issue  costs  from  the  Existing  Notes  are  being  amortized  as  an  adjustment  of  interest  expense  over  the 
term of the New 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 $2 million 
and were included in interest expense during the third quarter.  

Debt  Redemptions  –  On  March  22,  2010,  we  redeemed  $175  million  of  our  6.5%  notes  due  April  15, 
2012.  The  redemption  resulted  in  an  early  extinguishment  charge  of  $16  million  in  the  first  quarter  of 
2010.   On November 1, 2010, we redeemed all $400 million of our outstanding 6.65% notes due January 
15, 2011.  The redemption resulted in a $5 million early extinguishment charge.  

Receivables Securitization Facility – In June 2009, the Financial Accounting Standards Board (FASB) 
issued  Accounting  Standards  Update  No.  2009-16,  Accounting  for  Transfers  of  Financial  Assets  (ASU 
2009-16).    ASU  2009-16  limits  the  circumstances  in  which  transferred  financial  assets  can  be 
derecognized and requires enhanced disclosures regarding transfers of financial assets and a transferor’s 
continuing  involvement  with  transferred  financial  assets.    We  adopted  the  authoritative  accounting 
standard on January 1, 2010. As a result, we no longer account for the value of the outstanding undivided 
interest  held  by  investors  under  our  receivables  securitization  facility  as  a  sale.  In  addition,  transfers  of 
receivables  occurring  on  or  after  January  1,  2010,  are  reflected  as  debt  issued  in  our  Consolidated 
Statements  of  Cash  Flows,  and  the  value  of  the  outstanding  undivided  interest  held  by  investors  at 
December  31,  2010,  is  accounted  for  as  a  secured  borrowing  and  is  included  in  our  Consolidated 
Statements of Financial Position as debt due after one year. 

Under  the  receivables  securitization  facility,  the  Railroad  sells  most  of  its  accounts  receivable  to  Union 
Pacific  Receivables,  Inc.  (UPRI),  a  bankruptcy-remote  subsidiary.  UPRI  may  subsequently  transfer, 
without  recourse  on  a  364-day  revolving  basis,  an  undivided  interest  in  eligible  accounts  receivable  to 
investors. The total capacity to transfer undivided interests to investors under the facility was $600 million 
at  December  31,  2010  and  2009,  respectively.  The  value  of  the  outstanding  undivided  interest  held  by 
investors  under  the  facility  was  $100  million  and  $400  million  at  December  31,  2010  and  2009, 
respectively.  The  value  of  the  undivided  interest  held  by  investors  was  supported  by  $960  million  and 
$817  million  of  accounts  receivable  at  December  31,  2010  and  2009,  respectively.    At  December  31, 
2010  and  2009,  the  value  of  the  interest  retained  by  UPRI  was  $960  million  and  $417  million, 
respectively. This retained interest is included in accounts receivable, net in our Consolidated Statements 
of Financial Position. 

The  value  of  the  outstanding  undivided  interest  held  by  investors  could  fluctuate  based  upon  the 
availability of eligible receivables and is directly affected by changing business volumes and credit risks, 
including  default  and  dilution.  If  default  or  dilution  ratios  increase  one  percent,  the  value  of  the 
outstanding undivided interest held by investors would not change as of December 31, 2010. Should our 
credit rating fall below investment grade, the value of the outstanding undivided interest held by investors 
would be reduced, and, in certain cases, the investors would have the right to discontinue the facility.  

The Railroad collected approximately $16.3 billion and $13.8 billion of receivables during the years ended 
December  31,  2010  and  2009,  respectively.    UPRI  used  certain  of  these  proceeds  to  purchase  new 
receivables under the facility.  

The  costs  of  the  receivables  securitization  facility  include  interest,  which  will  vary  based  on  prevailing 
commercial  paper  rates,  program  fees  paid  to  banks,  commercial  paper  issuing  costs,  and  fees  for 
unused commitment availability.  The costs of the receivables securitization facility are included in interest 
expense and were $6 million during 2010.  Prior to adoption of the new accounting standard, the costs of 
the receivables securitization facility were included in other income and were $9 million and $23 million 
for 2009 and 2008, respectively.   

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

In  August  2010,  the  receivables  securitization  facility  was  renewed  for  an  additional  364-day  period  at 
comparable terms and conditions.

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, 2010:

Off-Balance Sheet Arrangements 

Guarantees  –  At  December  31,  2010,  we  were  contingently  liable  for  $382  million  in  guarantees.  We 
have recorded a liability of $3 million for the fair value of these obligations as of December 31, 2010 and 
2009.  We  entered  into  these  contingent  guarantees  in  the  normal  course  of  business,  and  they  include 
guaranteed  obligations  related  to  our  headquarters  building,  equipment  financings,  and  affiliated

operations.  The  final  guarantee  expires  in  2022.  We  are  not  aware  of  any  existing  event  of  default  that 
would require us to satisfy these guarantees. We do not expect that these guarantees will have a material 
adverse effect on our consolidated financial condition, results of operations, or liquidity. 

OTHER MATTERS 

Inflation  –  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,  2010  and  2009,  we  were  not  required  to 
provide collateral, nor had we received collateral, relating to our hedging activities. 

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

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

At  December  31,  2010,  we  had  variable-rate  debt  representing  approximately  2.2%  of  our  total  debt.  If 
variable interest rates average one percentage point higher in 2011 than our December 31, 2010 variable 
rate,  which  was  approximately  0.9%,  our  interest  expense  would  increase  by  approximately  $2  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, 2010.  

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, 2010, and amounts to 
an  increase  of  approximately  $824  million  to  the  fair  value  of  our  debt  at  December  31,  2010.  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  FASB 

41 

 
 
 
 
 
 
 
 
 
 
 
Accounting  Standards  Codification  (ASC);  therefore,  we  do  not  record  any  ineffectiveness  within  our 
Consolidated Financial Statements.  

Interest  Rate  Cash  Flow  Hedges  –  We  report  changes  in  the  fair  value  of  cash  flow  hedges  in 
accumulated other comprehensive loss until the hedged item affects earnings. At December 31, 2010 and 
2009, we had reductions of $3 million recorded as an accumulated other comprehensive loss that is being 
amortized on a straight-line basis through September 30, 2014. As of December 31, 2010 and 2009, we 
had no interest rate cash flow hedges outstanding. 

Recently Issued Accounting Pronouncements – In June 2009, the FASB issued Accounting Standards 
Update No. 2009-16, Accounting for Transfers of Financial Assets (ASU 2009-16).  ASU 2009-16 limits 
the  circumstances  in  which  transferred  financial  assets  can  be  derecognized  and  requires  enhanced 
disclosures  regarding  transfers  of  financial  assets  and  a  transferor’s  continuing  involvement  with 
transferred financial assets.  We adopted the authoritative accounting standard on January 1, 2010.  As a 
result, we no longer account for the value of the outstanding undivided interest held by investors under 
our receivables securitization facility as a sale.  In addition, transfers of receivables occurring on or after 
January  1,  2010,  are  reflected  as  debt  issued  in  our  Consolidated  Statements  of  Cash  Flows  and 
recognized as debt due after one year in our Consolidated Statements of Financial Position.   

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

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

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

CRITICAL ACCOUNTING POLICIES 

Our Consolidated Financial Statements have been prepared in accordance with GAAP. The preparation 
of  these  financial  statements  requires  estimation  and  judgment  that  affect  the  reported  amounts  of 
revenues,  expenses,  assets,  and  liabilities.  We  base  our  estimates  on  historical  experience  and  on 
various other assumptions that we believe are reasonable under the circumstances, the results of which 
form the basis for making judgments about the carrying values of assets and liabilities that are not readily 
apparent  from  other  sources.  The  following  critical  accounting  policies  are  a  subset  of  our  significant 
accounting  policies  described  in  Note  2  to  the  Financial  Statements  and  Supplementary  Data,  Item  8. 
These critical accounting policies affect significant areas of our financial statements and involve judgment 
and  estimates.  If  these  estimates  differ  significantly from actual results, the  impact  on  our  Consolidated 
Financial Statements may be material.  

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 

42 

 
 
 
 
 
 
 
 
 
are  assessed  based  on  a  finding  of  fault  through  litigation  or  out-of-court  settlements.  We  offer  a 
comprehensive variety of services and rehabilitation programs for employees who are injured at work.  

Our  personal  injury  liability  is  discounted  to  present  value  using  applicable  U.S.  Treasury  rates. 
Approximately 88% of the recorded liability related to asserted claims, and approximately 12% related to 
unasserted claims at December 31, 2010. 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  $426  million  to  $464  million.  We  record  an  accrual  at  the  low  end  of  the  range  as  no 
amount of loss is more probable than any other. Our personal injury liability activity was as follows:

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

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

averages.  

•  The percentage of claims dismissed in the future will be equivalent to historical averages.  

Our  liability  for  asbestos-related  claims  is  not  discounted  to  present  value  due  to  the  uncertainty 
surrounding the timing of future payments. Approximately 22% of the recorded liability related to asserted 
claims  and  approximately  78%  related  to  unasserted  claims  at  December  31,  2010.    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 $162 million to $178 million.  We record 
an  accrual  at  the  low  end  of  the  range  as  no  amount  of  loss  is  more  probable  than  any  other.      In 
conjunction  with  the  liability  update  performed  in  2010,  we  also  reassessed  estimated  insurance 
recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2010 and 
2009.  Our asbestos-related liability activity was as follows:

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

Environmental  –  We  are  subject  to  federal,  state,  and  local  environmental  laws  and  regulations.  We 
identified  294  sites  at  which  we  are  or  may  be  liable  for  remediation  costs  associated  with  alleged 
contamination or for violations of environmental requirements. This includes 31 sites that are the subject 
of actions taken by the U.S. government, 17 of which are currently on the Superfund National Priorities 
List.  Certain  federal  legislation  imposes  joint  and  several  liability  for  the  remediation  of  identified  sites; 
consequently, our ultimate environmental liability may include costs relating to activities of other parties, 
in addition to costs relating to our own activities at each site.  

When  we  identify  an  environmental  issue  with  respect  to  property  owned,  leased,  or  otherwise  used  in 
our business, we and our consultants perform environmental assessments on the property. We expense 
the  cost  of  the  assessments  as  incurred.  We  accrue  the  cost  of  remediation  where  our  obligation  is 
probable  and  we  can  reasonably  estimate  such  costs.  We  do  not  discount  our  environmental  liabilities 
when the timing of the anticipated cash payments is not fixed or readily determinable. At December 31, 
2010, approximately 5% of our environmental liability was discounted at 2.8%, while approximately 12% 
of our environmental liability was discounted at 3.4% at December 31, 2009. Our environmental liability

The liability includes future costs for remediation and restoration of sites, as well as ongoing monitoring 
costs, but excludes any anticipated recoveries from third parties. Cost estimates are based on information 
available for each site, financial viability of other potentially responsible parties, and existing technology, 
laws, and regulations. The ultimate liability for remediation is difficult to determine because of the number 
of  potentially  responsible  parties,  site-specific  cost  sharing  arrangements  with  other  potentially 
responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric 
data  related  to  many  of  the  sites,  and  the  speculative  nature  of  remediation  costs.  Estimates  of  liability 

44 

 
 
 
  
 
 
 
 
  
  
 
 
  
 
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, 
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 2010, 
the estimated service lives of the majority of this rail ranged from approximately 15 years to approximately 
30 years.  For all other depreciable assets, we compute depreciation based on the estimated service lives 
of  our  assets  as  determined  from  the  analysis  of  our  depreciation  studies.    Changes  in  the  estimated 
service lives of our assets and their related depreciation rates are implemented prospectively. 

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

Changes  in  estimated  useful  lives  of  our  assets  due  to  the  results  of  our  depreciation  studies  could 
significantly impact future periods’ depreciation expense and have a material impact on our Consolidated 
Financial Statements.  If the estimated useful lives of all depreciable assets were increased by one year, 
annual depreciation expense would decrease by approximately $42 million.  If the estimated useful lives 
of  all  depreciable  assets  were  decreased  by  one  year,  annual  depreciation  expense  would  increase  by 
approximately $45 million.  Our recent depreciation studies have resulted in changes in depreciation rates 
for some asset classes, but did not significantly affect our annual depreciation expense. 

45 

 
 
 
 
 
 
 
 
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.  During the last three fiscal years, no gains or losses were recognized due to the 
retirement of depreciable railroad properties.  A gain or loss is recognized in other income when we sell 
land or dispose of assets that are not part of our railroad operations.   

Income Taxes – We account for income taxes by recording taxes payable or refundable for the current 
year and deferred tax assets and liabilities for the expected future tax consequences of events that have 
been recognized in our financial statements or tax returns. These expected future tax consequences are 
measured based on current tax law; the effects of future changes in tax laws are not anticipated.  Future 
tax law changes, such as a change in the corporate tax rate, could have a material impact on our financial 
condition, results of operations, or liquidity.  For example, a 1% increase in future income tax rates would 
increase our deferred tax liability by approximately $300 million. 

When appropriate, we record a valuation allowance against deferred tax assets to reflect that these tax 
assets  may  not  be  realized.  In  determining  whether  a  valuation  allowance  is  appropriate,  we  consider 
whether it is more likely than not that all or some portion of our deferred tax assets will not be realized, 
based  on  management’s  judgments  using  available  evidence  about  future  events.    In  2010,  there  is  no 
valuation  allowance  because  the  deferred  tax  assets  associated  with  the  2009  valuation  allowance 
expired unrealized. Our total valuation allowance at December 31, 2009 was $8 million. 

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

Pension  and  Other  Postretirement  Benefits  –  We  use  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.

Our  net  periodic  pension  cost  is  expected  to  increase  to  approximately  $79  million  in  2011  from  $51 
million  in  2010.    The  increase  is  driven  by  a  decrease  in  the  discount  rate  to  5.35%,  a  decrease  in  our 
expected  rate  of  return  on  plan  assets  to  7.5%,  and  an  increase  in  the  amortization  of  actuarial  losses 
from accumulated other comprehensive income.  We reduced our expected rate of return on plan assets 
to  7.5%  in  2011  from  8%  in  2010  to  reflect  our  expected  future  returns  on  plan  assets  based  on  our 
current  asset  allocation  strategy.    Our  net  periodic  OPEB  benefit  is  expected  to  decrease  to 
approximately  $(4)  million  in  2011  from  $(14)  million  in  2010.    The  decrease  in  our  net  periodic  OPEB 
benefit  is  primarily  driven  by  a  decrease  in  the  amortization  of  prior  service  credits  from  accumulated 
other comprehensive income.

Forward-looking statements should not be read as a guarantee of future performance or results, and will 
not necessarily be accurate indications of the times that, or by which, such performance or results will be 
achieved.  Forward-looking  statements  and  information  are  subject  to  risks  and  uncertainties  that  could 
cause  actual  performance  or  results  to  differ  materially  from  those  expressed  in  the  statements  and 
information.    Forward-looking  statements  and  information  reflect  the  good  faith  consideration  by 
management of currently available information, and may be based on underlying assumptions believed to 
be  reasonable  under  the  circumstances.  However,  such  information  and  assumptions  (and,  therefore, 
such  forward-looking  statements  and  information)  are  or  may  be  subject  to  variables  or  unknown  or 
unforeseeable events or circumstances over which management has little or no influence or control.  The 
Risk Factors in Item 1A of this report could affect our future results and could cause those results or other 
outcomes  to  differ  materially  from  those  expressed  or  implied  in  any  forward-looking  statements  or 
information.  To  the  extent  circumstances  require  or  we  deem  it  otherwise  necessary,  we  will  update  or 
amend  these  risk  factors  in  a  Form  10-Q,  Form  8-K  or  subsequent  Form  10-K.    All  forward-looking 
statements are qualified by, and should be read in conjunction with, these Risk Factors. 

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Union Pacific Corporation, its Directors, and Shareholders:  

We  have  audited  the  accompanying  consolidated  statements  of  financial  position  of  Union  Pacific 
Corporation  and  Subsidiary  Companies  (the  Corporation)  as  of  December 31,  2010  and  2009,  and  the 
related consolidated statements of income, changes in common shareholders’ equity, and cash flows for 
each  of  the  three  years  in  the  period  ended  December 31,  2010.  Our  audits  also  included  the  financial 
statement  schedule  listed  in  the  Table  of  Contents  at  Part  IV,  Item  15.  These  financial  statements  and 
financial statement schedule are the responsibility of the Corporation’s management. Our responsibility is 
to  express  an  opinion  on  the  consolidated  financial  statements  and  financial  statement  schedule  based 
on our audits. 

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

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial 
position of Union Pacific Corporation and Subsidiary Companies as of December 31, 2010 and 2009, and 
the  results  of  their  operations  and  their  cash  flows  for  each  of  the  three  years  in  the  period  ended 
December 31,  2010,  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, 
2010,  based  on  the  criteria  established  in  Internal  Control —  Integrated  Framework  issued  by  the 
Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 4, 
2011, expressed an unqualified opinion on the Corporation’s internal control over financial reporting.

For  purposes  of  this  report,  unless  the  context  otherwise  requires,  all  references  herein  to  the 
“Corporation”, “UPC”, “we”, “us”, and “our” mean Union Pacific Corporation and its subsidiaries, including

1. Nature of Operations 

Operations  and  Segmentation  –  We  are  a  Class  I  railroad  that  operates  in  the  U.S.  We  have  31,953 
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 for the handling of freight to and from the Atlantic 
Coast, the Pacific Coast, the Southeast, the Southwest, Canada, and Mexico. Export and import traffic is 
moved through Gulf Coast and Pacific Coast ports and across the Mexican and Canadian borders. 

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

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

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.   

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. 

55 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 life 
are  grouped  together  in  asset  classes,  and  are  depreciated  using  composite  depreciation  rates.    The 
group method of depreciation treats each asset class as a pool of resources, not as singular items.  We 
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 to our interest rate fair value 
hedges. 

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.  

56 

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

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

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

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

Pension and Postretirement Benefits – We incur certain employment-related expenses associated with 
pensions  and  postretirement  health  benefits.  In  order  to  measure  the  expense  associated  with  these 
benefits,  we  must  make  various  assumptions  including  discount  rates  used  to  value  certain  liabilities, 
expected return on plan assets used to fund these expenses, salary increases, employee turnover rates, 
anticipated mortality rates, and expected future 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  discounted  to  present  value  using 
applicable U.S. Treasury rates. Legal fees and incidental costs are expensed as incurred.  

Asbestos  –  We  estimate  a  liability  for  asserted  and  unasserted  asbestos-related  claims  based  on  an 
assessment of the number and value of those claims. We use 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  and  our  consultants 
perform  environmental  assessments  on  such  property.  We  expense  the  cost  of  the  assessments  as 
incurred.  We  accrue  the  cost  of  remediation  where  our  obligation  is  probable  and  such  costs  can  be 
reasonably estimated. We do not discount our environmental liabilities when the timing of the anticipated 
cash  payments  is  not  fixed  or  readily  determinable.  Legal  fees  and  incidental  costs  are  expensed  as 
incurred. 

3. Recently Issued Accounting Pronouncements  

In June 2009, the FASB issued Accounting Standards Update No. 2009-16, Accounting for Transfers of 
Financial  Assets  (ASU  2009-16).    ASU  2009-16  limits  the  circumstances  in  which  transferred  financial 
assets  can  be  derecognized  and  requires  enhanced  disclosures  regarding  transfers  of  financial  assets 
and a transferor’s continuing involvement with transferred financial assets.  We adopted the authoritative 
accounting  standard  on  January  1,  2010.    As  a  result,  we  no  longer  account  for  the  value  of  the 
outstanding undivided interest held by investors under our receivables securitization facility as a sale.  In 
addition, transfers of receivables occurring on or after January 1, 2010, are reflected as debt issued in our 
Consolidated Statements of Cash Flows and recognized as debt due after one year in our Consolidated 
Statements of Financial Position.  (See the discussion of our receivables securitization facility in Note 10.)

4. Stock Options and Other Stock Plans 

We  have  12,542  options  outstanding  under  the  1993  Stock  Option  and  Retention  Stock  Plan  of  Union 
Pacific Corporation (1993 Plan). There are 7,140 restricted shares outstanding under the 1992 Restricted 
Stock  Plan  for  Non-Employee  Directors  of  Union  Pacific  Corporation.  We  no  longer  grant  options  or 
awards of retention shares and units under these plans.  

In  April  2000,  the  shareholders  approved  the  Union  Pacific  Corporation  2000  Directors  Plan  (Directors 
Plan) whereby 1,100,000 shares of our common stock were reserved for issuance to our non-employee 
directors.  Under  the  Directors  Plan,  each  non-employee  director,  upon  his  or  her  initial  election  to  the 
Board of Directors, receives a grant of 2,000 retention shares or retention stock units. Prior to December 
31, 2007, each non-employee director received annually an option to purchase at fair value a number of 
shares  of  our  common  stock,  not  to  exceed  10,000  shares  during  any  calendar  year,  determined  by 
dividing  60,000  by  1/3  of  the  fair  market  value  of  one  share  of  our  common  stock  on  the  date  of  such 
Board of Directors meeting, with the resulting quotient rounded up or down to the nearest 50 shares.  In 
September  2007,  the  Board  of  Directors  eliminated  the  annual  payment  of  options  for  2008  and  future 
years.  As of December 31, 2010, 18,000 restricted shares and 264,000 options were outstanding under 
the Directors Plan. 

The Union Pacific Corporation 2001 Stock Incentive Plan (2001 Plan) was approved by the shareholders 
in  April  2001.  The  2001  Plan  reserved  24,000,000  shares  of  our  common  stock  for  issuance  to  eligible 
employees  of  the  Corporation  and  its  subsidiaries  in  the  form  of  non-qualified  options,  incentive  stock 
options,  retention  shares,  stock  units,  and  incentive  bonus  awards.  Non-employee  directors  were  not 
eligible for awards under the 2001 Plan. As of December 31, 2010, 1,861,066 options were outstanding 
under the 2001 Plan. We no longer grant any stock options or other stock or unit awards under this plan.  

The Union Pacific Corporation 2004 Stock Incentive Plan (2004 Plan) was approved by shareholders in 
April  2004.  The  2004  Plan  reserved  42,000,000  shares  of  our  common  stock  for  issuance,  plus  any 
shares subject to awards made under the 2001 Plan and the 1993 Plan that were outstanding on April 16, 
2004,  and  became  available  for  regrant  pursuant  to  the  terms  of  the  2004  Plan.  Under  the  2004  Plan, 
non-qualified options, stock appreciation rights, retention shares, stock units, and incentive bonus awards 
may be granted to eligible employees of the Corporation and its subsidiaries. Non-employee directors are 
not eligible for awards under the 2004 Plan. As of December 31, 2010, 7,677,841 options and 3,788,877 
retention shares and stock units were outstanding under the 2004 Plan.  

Pursuant to the above plans 32,904,291; 33,559,150; and 36,961,123 shares of our common stock were 
authorized and available for grant at December 31, 2010, 2009, and 2008, 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:

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

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.

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, 2010 are subject to performance or market-based vesting conditions. 

At  December  31,  2010,  there  was  $17  million  of  unrecognized  compensation  expense  related  to 
nonvested  stock  options,  which  is  expected  to  be  recognized  over  a  weighted-average  period  of  0.9 
years. Additional information regarding stock option exercises appears in the table below:

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

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, 2010, there was $62 million of total unrecognized compensation 
expense  related  to  nonvested  retention  awards,  which  is  expected  to  be  recognized  over  a  weighted-
average period of 1.7 years. 

Performance  Retention  Awards  –  In  February  2010,  our  Board  of  Directors  approved  performance 
stock  unit  grants.  Other  than  different  performance  targets,  the  basic  terms  of  these  performance  stock 
units are identical to those granted in January 2008 and February 2009, 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.  In February 2009, 
we  changed  an  underlying  assumption  used  in  connection  with  calculating  a  component  of  ROIC.  As  a 
result,  for  awards  of  performance  stock  units  granted  in  2009  and  2010,  an  assumed  interest  rate  was 
used in both the numerator and denominator when calculating the present value of our future operating 
lease  payments  to  reflect  changes  to  interest  rates  and  our  financing  costs.  This  rate  is  consistent  with 
the methodology used to calculate our adjusted debt-to-capital ratio.  For performance stock units granted 
in  2008,  we  calculated  ROIC  using  the  methodology  and  assumptions  in  effect  when  the  performance 
stock units were granted.   

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 2010 grant were as follows: 

 Dividend per share per quarter

nonvested  performance  retention  awards,  which  is  expected  to  be  recognized  over  a  weighted-average 
period of 1.2 years. A portion of this expense is subject to achievement of the ROIC levels established for 
the performance stock unit grants. 

5. Retirement Plans 

Pension and Other Postretirement Benefits  

Pension Plans – We provide defined benefit retirement income to eligible non-union employees through 
qualified and non-qualified (supplemental) pension plans. Qualified and non-qualified pension benefits are 
based  on  years  of  service  and  the  highest  compensation  during  the  latest  years  of  employment,  with 
specific reductions made for early retirements. 

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

Plan Amendment 

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

Funded Status  

We are required by GAAP to separately recognize the overfunded or underfunded status of our pension 
and OPEB plans as an asset or liability. The funded status represents the difference between the PBO 
and  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  salary  increases.  The  PBO  of  the  OPEB  plan  is  equal  to  the 
accumulated  benefit  obligation,  as  the  present  value  of  the  OPEB  liabilities  is  not  affected  by  salary 
increases.  Plan  assets  are  measured  at  fair  value.  We  use  a  December  31  measurement  date  for  plan 
assets and obligations for all our retirement plans.  

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

Underfunded Accumulated Benefit Obligation – The accumulated benefit obligation (ABO) is the present 
value of benefits earned to date, assuming no future salary growth. The underfunded accumulated benefit 
obligation represents the difference between the ABO and the fair value of plan assets. At December 31, 
2010  and  2009,  the  non-qualified  (supplemental)  plan  ABO  was  $257  million  and  $229  million, 
respectively.  The  PBO,  ABO,  and  fair  value  of  plan  assets  for  pension  plans  with  accumulated  benefit 
obligations in excess of the fair value of the plan assets were as follows for the years ended December 
31:

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

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

The  discount  rate  was  based  on  a  Mercer  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  (loss)  on  pension  plan  assets,  net  of  fees,  was  approximately  14%  in  2010,  23%  in 
2009, and (30)% in 2008.

Assumed health care cost trend rates have a significant 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 2011 assumed health care cost trend rate for employees under 65 is 7.07%.  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  health  care  cost  trend  rates  would  have  the  following 
effects on OPEB:

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 2010 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  2011  supplemental  pension  and  OPEB 
payments will be made from cash generated from operations.

The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to 
achieve our target of an average long-term rate of return of 7.5%. We reduced our expected rate of return 
on  plan  assets  to  7.5%  in  2011  from  8%  in  2010  to  reflect  our  expected  future  returns  on  plan  assets 
based  on  our  current  asset  allocation  strategy.    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  external 
consulting firm. Actual asset allocations are monitored monthly, and rebalancing actions are executed at 
least quarterly, if needed.  

The pension plan investments are held in a Master Trust, with The Northern Trust Company. The majority 
of  pension  plan  assets  are  invested  in  equity  securities  because  equity  portfolios  have  historically 
provided higher returns than debt and other asset classes over extended time horizons and are expected 
to  do  so  in  the  future.  Correspondingly,  equity  investments  also  entail  greater  risks  than  other 
investments.    Equity  risks  are  balanced  by  investing  a  significant  portion  of  the  plans’  assets  in  high 
quality debt securities. The average credit rating of the debt portfolio exceeded A+ as of December 31, 
2010  and  2009.  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, 2010 and 2009.  

The investment of pension plan assets in securities  issued by Union Pacific is specifically 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.  Foreign currencies held are reported in terms 
of  U.S.  dollars  based  on  currency  exchange  rates  readily  available  in  active  markets.  These  temporary 
cash investments are classified as Level 1 investments. 

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

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

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

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

Venture  Capital  and  Buyout  Partnerships  –  This  investment  category  is  comprised  of  interests  in 
limited partnerships that invest in privately-held companies.  Due to the private nature of the partnership 

65 

 
 
 
 
 
 
 
 
 
 
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.    Holdings  of  limited  partnership  interests  are  classified  as 
Level 3 investments.   

Real  Estate  Partnerships  and  Funds  –  Most  of  the  real  estate  investments  are  partnership  interests 
similar to those described in the Venture Capital and Partnerships category.  This category also includes 
real  estate  investments  held  in  less  commonly  used  structures  such  as  private  real  estate  investment 
trusts and pooled separate accounts.  Valuations for the holdings in this category are not based on readily 
observable  inputs  and  are  primarily  derived  from  property  appraisals.    Interests  in  private  real  estate 
partnerships, investment funds and pooled separate accounts 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 (equity securities, fixed income 
securities, and commodity-related securities) are  publicly traded on exchanges and price quotes for the 
assets held by these funds are readily available. Holdings of common trust funds are classified as Level 2 
investments. 

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

Other  Investments  –  This  category  includes  several  miscellaneous  assets  such  as  commodity  hedge 
fund  investments.    These  investments  have  valuations  that  are  based  on  observable  inputs  and  are 
classified as Level 2 investments. 

As of December 31, 2010, 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 
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 $13 million 
in 2010, $14 million in 2009 and $14 million 2008.

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 $566 million in 2010, $562 million in 2009, and $620 million in 2008. 

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 
$60 million in 2010, $48 million in 2009, and $49 million in 2008.

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

In  January  of  2008,  Illinois  enacted  legislation  that  changed  how  we  determine  the  amount  of  income 
subject to Illinois tax.  This change reduced our 2008 deferred tax expense by $16 million. 

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

When appropriate, we record a valuation allowance against deferred tax assets to reflect that these tax 
assets  may  not  be  realized.  In  determining  whether  a  valuation  allowance  is  appropriate,  we  consider 
whether it is more likely than not that all or some portion of our deferred tax assets will not be realized, 
based  on  management’s  judgments  using  available  evidence  about  future  events.    In  2010,  there  is  no 
valuation  allowance  because  the  deferred  tax  assets  associated  with  the  2009  valuation  allowance 
expired unrealized. Our total valuation allowance at December 31, 2009 was $8 million. 

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

We  recognize  interest  and  penalties  as  part  of  income  tax  expense.  Total  accrued  liabilities  for  interest 
and  penalties  were  $19  million  and  $13  million  at  December  31,  2010  and  2009,  respectively.  Total 
interest and penalties recognized as part of income tax expense (benefit) were $6 million for 2010, $(11) 
million for 2009, and $(9) million for 2008.  

Internal Revenue Service (IRS) examinations have been completed and settled for all years prior to 1999, 
and  the  statute  of  limitations  bars  any  additional  tax  assessments.    Some  interest  calculations  remain 
open  back  to  1986.    The  IRS  has  completed  its  examinations  and  issued  notices  of  deficiency  for  tax 
years  1999  through  2006.  We  disagree  with  many  of  their  proposed  adjustments,  and  we  are  at  IRS 
Appeals for these years.  We anticipate a partial settlement of the tax years 1999-2004 during 2011.  The 
IRS  is  examining  the  Corporation’s  federal  income  tax  returns  for  2007  and  2008.    Several  state  tax 
authorities are examining our state income tax returns for tax years 2003 through 2006. 

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

We  expect  our  unrecognized  tax  benefits  to  decrease  significantly  in  the  next  12  months.    Of  the  $86 
million balance at December 31, 2010, $68 million is classified as current in the Consolidated Statement 
of  Financial  Position,  in  anticipation  of  a  partial  settlement  of  the  1999-2004  tax  years,  as  well  as  a 
reasonable possibility that some state tax disputes will be resolved in 2011.

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.

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,  2010  and  2009,  our  accounts  receivable  were  reduced  by  $5 
million  and  $3  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 
Position.  At  December  31,  2010  and  2009,  receivables  classified  as  other  assets  were  reduced  by 
allowances of $51 million and $67 million, respectively.

Receivables Securitization Facility – As discussed in Note 3, we adopted a new accounting standard 
on January 1, 2010.  As a result, we no longer account for the value of the outstanding undivided interest 
held  by  investors  under  our  receivables  securitization  facility  as  a  sale.  In  addition,  transfers  of 
receivables  occurring  on  or  after  January  1,  2010,  are  reflected  as  debt  issued  in  our  Consolidated 
Statements  of  Cash  Flows,  and  the  value  of  the  outstanding  undivided  interest  held  by  investors  at 
December  31,  2010,  is  accounted  for  as  a  secured  borrowing  and  is  included  in  our  Consolidated 
Statements of Financial Position as debt due after one year. 

Under  the  receivables  securitization  facility,  the  Railroad  sells  most  of  its  accounts  receivable  to  Union 
Pacific  Receivables,  Inc.  (UPRI),  a  bankruptcy-remote  subsidiary.  UPRI  may  subsequently  transfer, 
without  recourse  on  a  364-day  revolving  basis,  an  undivided  interest  in  eligible  accounts  receivable  to 
investors. The total capacity to transfer undivided interests to investors under the facility was $600 million 
at  December  31,  2010  and  2009,  respectively.  The  value  of  the  outstanding  undivided  interest  held  by 
investors  under  the  facility  was  $100  million  and  $400  million  at  December  31,  2010  and  2009, 
respectively.  The  value  of  the  undivided  interest  held  by  investors  was  supported  by  $960  million  and 
$817  million  of  accounts  receivable  at  December  31,  2010  and  2009,  respectively.    At  December  31, 
2010  and  2009,  the  value  of  the  interest  retained  by  UPRI  was  $960  million  and  $417  million, 
respectively. This retained interest is included in accounts receivable, net in our Consolidated Statements 
of Financial Position. 

The  value  of  the  outstanding  undivided  interest  held  by  investors  could  fluctuate  based  upon  the 
availability of eligible receivables and is directly affected by changing business volumes and credit risks, 
including  default  and  dilution.  If  default  or  dilution  ratios  increase  one  percent,  the  value  of  the 
outstanding undivided interest held by investors would not change as of December 31, 2010. Should our 
credit rating fall below investment grade, the value of the outstanding undivided interest held by investors 
would be reduced, and, in certain cases, the investors would have the right to discontinue the facility.  

The Railroad collected approximately $16.3 billion and $13.8 billion of receivables during the years ended 
December  31,  2010  and  2009,  respectively.    UPRI  used  certain  of  these  proceeds  to  purchase  new 
receivables under the facility.  

The  costs  of  the  receivables  securitization  facility  include  interest,  which  will  vary  based  on  prevailing 
commercial  paper  rates,  program  fees  paid  to  banks,  commercial  paper  issuing  costs,  and  fees  for 
unused commitment availability.  The costs of the receivables securitization facility are included in interest 
expense and were $6 million during 2010.  Prior to adoption of the new accounting standard, the costs of 
the receivables securitization facility were included in other income and were $9 million and $23 million 
for 2009 and 2008, respectively.   

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

In  August  2010,  the  receivables  securitization  facility  was  renewed  for  an  additional  364-day  period  at 
comparable terms and conditions.

Includes a weighted-average composite depreciation rate for rail in high-density traffic corridors as discussed below.

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.    These  costs  are  allocated  using  appropriate  statistical 
bases.  

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

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

13. Financial Instruments 

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

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,  2010  and  2009,  we  were  not  required  to 
provide collateral, nor had we received collateral, relating to our hedging activities. 

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

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

Swaps allow us to convert debt from fixed rates to variable rates and thereby hedge the risk of changes in 
the  debt’s  fair  value  attributable  to  the  changes  in  interest  rates.  We  account  for  swaps  as  fair  value 
hedges  using  the  short-cut  method;  therefore,  we  do  not  record  any  ineffectiveness  within  our 
Consolidated Financial Statements.

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

On February 25, 2010, we elected to terminate an interest rate swap agreement with a notional amount of 
$250 million prior to the scheduled maturity and received cash of $20 million (which is comprised of $16 
million  for  the  fair  value  of  the  swap  that  was  terminated  and  $4  million  of  accrued  but  unpaid  interest 
receivable).    We  designated  the  swap  agreement  as  a  fair  value  hedge,  and  as  such  the  unamortized 
adjustment to debt for the change in fair value of the swap remains classified as debt due after one year 
in  our  Consolidated  Statements  of  Financial  Position  and  will  be  amortized  as  a  reduction  to  interest 
expense through April 15, 2012.  As of December 31, 2010, we do not have any 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, 2010 and 
2009, we had reductions of $3 million recorded as an accumulated other comprehensive loss that is being 
amortized on a straight-line basis through September 30, 2014. As of December 31, 2010 and 2009, we 
had no interest rate cash flow hedges outstanding.  

Earnings Impact – Our use of derivative financial instruments had the following impact on pre-tax income 
for the years ended December 31:

Fair Value of Debt Instruments – The fair value of our short- and long-term debt was estimated using 
quoted market prices, where available, or current borrowing rates. At December 31, 2010, the fair value 
of total debt was $10.4 billion, approximately $1.2 billion more than the carrying value.  At December 31, 
2009,  the  fair  value  of  total  debt  was  $10.8  billion,  approximately  $945  million  more  than  the  carrying 
value.    At  December  31,  2010  and  2009,  approximately  $303  million  and  $320  million,  respectively,  of 
fixed-rate debt securities contained call provisions that allowed us to retire the debt instruments prior to 
final maturity, with the payment of fixed call premiums, or in certain cases, at par.

As of December 31, 2010, we have reclassified as long-term debt approximately $100 million of debt due 
within one year that we intend to refinance. This reclassification reflects our ability and intent to refinance 
any  short-term  borrowings  and  certain  current  maturities  of  long-term  debt  on  a  long-term  basis.    At 
December 31, 2009, we reclassified as long-term debt approximately $320 million of debt due within one 
year that we intended to refinance at that time. 

Mortgaged Properties – Equipment with a carrying value of approximately $3.2 billion and $3.4 billion at 
December  31,  2010  and  2009,  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  –  On  December  31,  2010,  we  had  $1.9  billion  of  credit  available  under  our  revolving 
credit  facility  (the  facility).  The  facility  is  designated  for  general  corporate  purposes  and  supports  the 
issuance of commercial paper. We did not draw on the facility during 2010. 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 

77 

 
 
 
 
 
  
 
 
 
 
Rates,  plus  a  spread,  depending  upon  our  senior  unsecured  debt  ratings.  The  facility  requires  us  to 
maintain a debt-to-net-worth coverage ratio as a condition to making a borrowing. At December 31, 2010, 
and  December  31,  2009  (and  at  all  times  during  these  periods),  we  were  in  compliance  with  this 
covenant. 

The  definition  of  debt  used  for  purposes  of  calculating  the  debt-to-net-worth  coverage  ratio  includes, 
among  other  things,  certain  credit  arrangements,  capital  leases,  guarantees  and  unfunded  and  vested 
pension  benefits  under  Title  IV  of  ERISA.  At  December  31,  2010,  the  debt-to-net-worth  coverage  ratio 
allowed us to carry up to $35.5 billion of debt (as defined in the facility), and we had $9.7 billion of debt 
(as defined in the facility) outstanding at that date.  Under our current capital plans, we expect to continue 
to  satisfy  the  debt-to-net-worth  coverage  ratio;  however,  many  factors  beyond  our  reasonable  control 
could affect our ability to comply with this provision in the future. The facility does not include any other 
financial  restrictions,  credit  rating  triggers  (other  than  rating-dependent  pricing),  or  any  other  provision 
that could require us to post collateral. The facility also includes a $75 million cross-default provision and 
a  change-of-control  provision.  The  facility  will  expire  in  April  2012  in  accordance  with  its  term,  and  we 
currently  intend  to  replace  the  facility  with  a  substantially  similar  credit  agreement  on  or  before  the 
expiration date, which is consistent with our past practices with respect to our credit facilities. 

During  2010,  we  did  not  issue  or  repay  any  commercial  paper  and,  at  December  31,  2010,  we  had  no 
commercial  paper  outstanding.  Outstanding  commercial  paper  balances  are  supported  by  our  revolving 
credit facility but do not reduce the amount of borrowings available under the facility.  

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 $12.9 billion 
and $11.6 billion at December 31, 2010 and 2009, respectively. 

Shelf  Registration  Statement  and  Significant  New  Borrowings  –  We  filed  a  new  shelf  registration 
statement, which became effective February 10, 2010. Our Board of Directors authorized the issuance of 
up  to  $3  billion  of  debt  securities,  replacing  the  $2.25  billion  of  authority  remaining  under  our  shelf 
registration  filed  in  March  2007.  Under  the  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.  

During  2010,  we  issued  the  following  unsecured,  fixed-rate  debt  securities  under  our  current  shelf 
registration: 

 Date 
 August 2, 2010 

Description of Securities 
$500 million of 4.00% Notes due February 1, 2021 

The net proceeds from the offering were used for general corporate purposes, including the repurchase of 
common  stock  pursuant  to  our  share  repurchase  program.  These  debt  securities  include  change-of-
control provisions. 

We have no immediate plans to issue equity securities; however, we will continue to explore opportunities 
to replace existing debt or access capital through issuances of debt securities under our shelf registration, 
and,  therefore,  we  may  issue  additional  debt  securities  at  any  time.    At  December  31,  2010,  we  had 
remaining authority to issue up to $2.5 billion of debt securities under our shelf registration. 

Debt Exchange – On July 14, 2010, we exchanged $376 million of 7.875% notes due in 2019 (Existing 
Notes)  for  5.78%  notes  (New  Notes)  due  July  15,  2040,  plus  cash  consideration  of  approximately  $96 
million  and  $15  million  for  accrued  and  unpaid  interest  on  the  Existing  Notes.    The  cash  consideration, 
recorded as an adjustment to the carrying value of debt, and the balance of the unamortized discount and 
issue  costs  from  the  Existing  Notes  are  being  amortized  as  an  adjustment  of  interest  expense  over  the 
term of the New 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 $2 million 
and were included in interest expense during the third quarter. 

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

78 

 
 
 
 
 
 
 
 
 
 
 
2010.   On November 1, 2010, we redeemed all $400 million of our outstanding 6.65% notes due January 
15, 2011.  The redemption resulted in a $5 million early extinguishment charge.   

Receivables Securitization Facility – At December 31, 2010, we have recorded $100 million as secured 
debt under our receivables securitization facility.  (See further discussion of our receivables securitization 
facility in Note 10.) 

15. Variable Interest Entities   

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

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

We  are  not  considered  to  be  the  primary  beneficiary  and  do  not  consolidate  these  VIEs  because  our 
actions and decisions do not have the most significant effect on the VIE’s performance and our fixed-price 
purchase price options are not considered to be potentially significant to the VIE’s.  The future minimum 
lease payments associated with the VIE leases totaled $4.2 billion as of December 31, 2010. 

16. Leases 

We lease certain locomotives, freight cars, and other property. The Consolidated Statement of Financial 
Position as of December 31, 2010 and 2009 included $2,520 million, net of $901 million of accumulated 
depreciation,  and  $2,754  million,  net  of  $927  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, 2010, were as follows:

The  majority  of  capital  lease  payments  relate  to  locomotives.  Rent  expense  for  operating  leases  with 
terms  exceeding  one  month  was  $624  million  in  2010,  $686  million  in  2009,  and  $747  million  in  2008. 
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.

17. Commitments and Contingencies 

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

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

Our  personal  injury  liability  is  discounted  to  present  value  using  applicable  U.S.  Treasury  rates. 
Approximately 88% of the recorded liability related to asserted claims, and approximately 12% related to 
unasserted claims at December 31, 2010. 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  $426  million  to  $464  million.  We  record  an  accrual  at  the  low  end  of  the  range  as  no 
amount of loss is more probable than any other.  Our personal injury liability activity was as follows:

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

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

averages.  

•  The percentage of claims dismissed in the future will be equivalent to historical averages.

Our  liability  for  asbestos-related  claims  is  not  discounted  to  present  value  due  to  the  uncertainty 
surrounding the timing of future payments. Approximately 22% of the recorded liability related to asserted 
claims  and  approximately  78%  related  to  unasserted  claims  at  December  31,  2010.    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 $162 million to $178 million.  We record 
an  accrual  at  the  low  end  of  the  range  as  no  amount  of  loss  is  more  probable  than  any  other.      In 
conjunction  with  the  liability  update  performed  in  2010,  we  also  reassessed  estimated  insurance 
recoveries. We have recognized an asset for estimated insurance recoveries at December 31, 2010 and 
2009.  Our asbestos-related liability activity was as follows:

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

Environmental  –  We  are  subject  to  federal,  state,  and  local  environmental  laws  and  regulations.  We 
identified  294  sites  at  which  we  are  or  may  be  liable  for  remediation  costs  associated  with  alleged 
contamination or for violations of environmental requirements. This includes 31 sites that are the subject 
of actions taken by the U.S. government, 17 of which are currently on the Superfund National Priorities 
List.  Certain  federal  legislation  imposes  joint  and  several  liability  for  the  remediation  of  identified  sites; 
consequently, our ultimate environmental liability may include costs relating to activities of other parties, 
in addition to costs relating to our own activities at each site.  

When  we  identify  an  environmental  issue  with  respect  to  property  owned,  leased,  or  otherwise  used  in 
our business, we and our consultants perform environmental assessments on the property. We expense 
the  cost  of  the  assessments  as  incurred.  We  accrue  the  cost  of  remediation  where  our  obligation  is 
probable  and  we  can  reasonably  estimate  such  costs.  We  do  not  discount  our  environmental  liabilities 
when the timing of the anticipated cash payments is not fixed or readily determinable. At December 31, 
2010, approximately 5% of our environmental liability was discounted at 2.8%, while approximately 12% 
of our environmental liability was discounted at 3.4% at December 31, 2009.  Our environmental liability 
activity was as follows:

The  environmental  liability  includes  future  costs  for  remediation  and  restoration  of  sites,  as  well  as 
ongoing monitoring costs, but excludes any anticipated recoveries from third parties. Cost estimates are 
based on information available for each site, financial viability of other potentially responsible parties, and 
existing  technology,  laws,  and  regulations.  The  ultimate  liability  for  remediation  is  difficult  to  determine 
because  of  the  number  of  potentially  responsible  parties,  site-specific  cost  sharing  arrangements  with 
other  potentially  responsible  parties,  the  degree  of  contamination  by  various  wastes,  the  scarcity  and 

81 

 
 
 
 
 
 
 
 
quality  of  volumetric  data  related  to  many  of  the  sites,  and  the  speculative  nature  of  remediation  costs. 
Estimates  of  liability  may  vary  over  time  due  to  changes  in  federal,  state,  and  local  laws  governing 
environmental remediation. Current obligations are not expected to have a material adverse effect on our 
consolidated results of operations, financial condition, or liquidity.  

Guarantees  –  At  December  31,  2010,  we  were  contingently  liable  for  $382  million  in  guarantees.  We 
have recorded a liability of $3 million for the fair value of these obligations as of December 31, 2010 and 
2009.  We  entered  into  these  contingent  guarantees  in  the  normal  course  of  business,  and  they  include 
guaranteed  obligations  related  to  our  headquarters  building,  equipment  financings,  and  affiliated 
operations.  The  final  guarantee  expires  in  2022.  We  are  not  aware  of  any  existing  event  of  default  that 
would require us to satisfy these guarantees. We do not expect that these guarantees will have a material 
adverse effect on our consolidated financial condition, results of operations, or liquidity. 

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

18.  Share Repurchase Program  

On May 1, 2008, our Board of Directors authorized the repurchase of 40 million common shares by March 
31, 2011. Management’s assessments of market conditions and other pertinent facts guide the timing and 
volume of all repurchases.  Any share repurchases under this program are expected to be funded 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.

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

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, 2010. 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. Based on our assessment, management believes that, as of December 31, 2010, 
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 

Union Pacific Corporation, its Directors, and Shareholders: 

We have audited the internal control over financial reporting of Union Pacific Corporation and Subsidiary 
Companies  (the  Corporation)  as  of  December 31,  2010,  based  on  criteria  established  in  Internal 
Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission. The Corporation's management is responsible for maintaining effective internal control over 
financial reporting and for its assessment of the effectiveness of internal control over financial reporting, 
included  in  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,  2010,  based  on  the  criteria  established  in  Internal  Control  —  Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight 
Board (United States), the consolidated financial statements and financial statement schedule as of and 
for  the  year  ended  December 31,  2010  of  the  Corporation  and  our  report  dated  February 4,  2011 
expressed an unqualified opinion on those financial statements and financial statement schedule.

1. I have reviewed this annual report on Form 10-K of Union Pacific Corporation; 

2. Based on my knowledge, this report does not contain any untrue statement of material fact or omit to 
state a material fact necessary to make the statements made, in light of the circumstances under which 
such statements were made, not misleading with respect to the period covered by this report; 

3.  Based  on  my  knowledge,  the  financial  statements,  and  other  financial  information  included  in  this 
report, fairly present in all material respects the financial condition, results of operations and cash flows of 
the registrant as of, and for, the periods presented in this report; 

4.  The  registrant’s  other  certifying  officer(s)  and  I  are  responsible  for  establishing  and  maintaining 
disclosure  controls  and  procedures  (as  defined  in  Exchange  Act  Rules  13a-15(e)  and  15d-15(e))  and 
internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the 
registrant and have: 

(a)  Designed such disclosure controls and procedures, or caused such disclosure controls and 
procedures to be designed under our supervision, to ensure that material information relating to 
the registrant, including its consolidated subsidiaries, is made known to us by others within those 
entities, particularly during the period in which this report is being prepared; 

(b)  Designed  such  internal  control  over  financial  reporting,  or  caused  such  internal  control  over 
financial  reporting  to  be  designed  under  our  supervision,  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; 

(c)    Evaluated  the  effectiveness  of  the  registrant’s  disclosure  controls  and  procedures  and 
presented  in  this  report  our  conclusions  about  the  effectiveness  of  the  disclosure  controls  and 
procedures, as of the end of the period covered by this report based on such evaluation; and 

(d)  Disclosed in this report any change in the registrant’s internal control over financial reporting 
that  occurred  during  the  registrant’s  most  recent  fiscal  quarter  (the  registrant’s  fourth  fiscal 
quarter  in  the  case  of  an  annual  report)  that  has  materially  affected,  or  is  reasonably  likely  to 
materially affect, the registrant’s internal control over financial reporting; and 

5. The registrant’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of 
internal  control  over  financial  reporting,  to  the  registrant’s  auditors  and  the  audit  committee  of  the 
registrant’s board of directors (or persons performing the equivalent functions): 

(a)    All  significant  deficiencies  and  material  weaknesses  in  the  design  or  operation  of  internal 
control  over  financial  reporting  which  are  reasonably  likely  to  adversely  affect  the  registrant’s 
ability to record, process, summarize and report financial information; and 

(b)  Any fraud, whether or not material, that involves management or other employees who have 
a significant role in the registrant’s internal control over financial reporting.
