To Our Shareholders

Over the intercom, the words were heard loud and clear by the crew of the 

Noble Don Taylor, a newbuild ultra-deepwater drillship being constructed 
for Noble. “Attention all Hands! This is the Captain speaking. We have been 
given  a  great  opportunity  to  be  onboard  the  Noble  Don  Taylor  for  this  maiden 
voyage.  To  quote  Henry  Ward  Beecher,  ‘It  is  not  the  going  out  of  port,  but  the 
coming  in  that  determines  the  success  of  a  voyage’.  The  safe  arrival  of  this  fine 
drilling vessel into the Gulf of Mexico is the responsibility of all hands onboard. 
Take no shortcuts, work safely and, as Noble employees, do it right the first time.”

Moments  later  as  the  ship  readies  for 
sea  trials,  the  Captain’s  departure  message 
is  greeted  with  cheers  as  he  gives  the 
command,  “Marine  team,  secure  for  sea  and 
stand  by  fore  and  aft  to  make  fast  tug  boats 
and  let  go  lines.  Chief  Mate,  bring  thrusters 
around  20  degrees  to  Port  and  give  me  10 
percent. Marine team, throw off the last lines. 
Chief  Mate,  dead  slow  ahead,  steady  as  she 
goes.  Attention  all  hands!  Job  well  done! 
Now the adventure begins! That is all…”

One  might  conclude  from  the  Captain’s 
message  that  this  is  the  start  of  something 
big for Noble. That conclusion would be only 
part  of  the  story,  however,  as  the  effort  that 
is  driving  the  modernization  of  the  Noble 
fleet spans back several years and embodies 
a new approach and vision for the Company. 

That  vision’s  focus  is  on  high-grading 
Noble — and  not  just  our  fleet.  Units  like 
the  Noble  Don  Taylor  are  a  highly  visible 
indicator  of  our  progress  toward  that  goal. 
leading-edge 
Our  newbuilds  are  also  a 
indicator  of 
fundamental  changes 
happening  within  Noble — both  from  an 
operating  perspective  and  as  an  investment 
opportunity.  With  each  new  milestone  we 
reach, we are making progress on the course 

the 

we  charted  for  Noble  and  moving  forward 
into  what  we  believe  is  a  very  promising 
future for the Company.

For  much  of  our  90  plus  year  history, 
Noble  benefited  from  riding  out  the  ever 
present  cycles  in  the  industry  by  upgrading 
units purchased from other drillers. This  was 
a sound business model that generated good 
returns and we were able to meet the needs 
of  our  customers  with  equipment  that  was 
made  “more  than  fit  for  purpose”  by  Noble. 
But  like  many  business  models,  it  had  its 
limits. 

the 

solution  as 

With each passing year, modernizing and 
modifying older units became an increasingly 
challenging 
technical 
requirements  of  a  maturing  industry  grew. 
This  does  not  imply  that  the  older  units  in 
our  fleet  aren’t  valuable;  in  fact,  the  reverse 
is  true.  Utilization  of  our  older  units  remains 
at  or  near  an  all-time  high.  Dayrates  as  well 
as  resulting  backlog  on  these  units  are 
significant. 

The  question,  however,  is  not  about 
today,  but  the  future  and  what  sort  of 
company Noble will be in our next 100 years. 
To  this  end,  we  are  taking  steps  to  balance 

our  fleet  by  adding  measurably  to  the  high-
specification  side  while  considering  options 
for some of the standard specification units. 

Our  newbuild  program,  which  saw  the 
successful  integration  of  three  new  ultra-
deepwater  drillships  into  the  fleet  in  2012, 
will  see  the  addition  of  six  more  units  this 
year  and  nearly  an  equal  number  in  2014 
when  five  more  units  join  the  ranks.  As  a 
result,  Noble’s  fleet  mix  will  be  significantly 
enhanced over the next two years. 

The  backlog  underpinning 

this  fleet 
modernization  is  unprecedented.  It  is  our 
expectation  that  it  will  also  position  us  to 
share  the  benefits  of  the  new  Noble  model 
with  our  shareholders.  Our  Board  has 
requested  shareholders  approve  increasing 
the dividend on our shares for the 2013-2014 
cycle,  further  illustrating  the  direction  we 
are  going  in  terms  of  creating  shareholder 
value and the overall positive outlook for the 
Company.

Noble  is  assembling  one  of  the  most 
technologically  advanced  and  operationally 
capable  fleets  in  the  industry.  The  members 
of the Noble team who will manage, operate 
and maintain these units are also being high-
graded  through  training  and  occupational

proficiency  efforts  designed

to  set 

employees  who  were  hired  in  the  1980s  or 
earlier.  This  demographic  reality,  known  as 
the  “great  crew  change”  in  industry  circles, 
dictates  that  we  would  have  had  significant 
hiring  needs  even  without 
the  current 
newbuild  cycle.  With  the  addition  of  an 
ongoing  newbuild  program  industry-wide, 
competition  for  the  best  people  is  nothing 
short of extraordinary. 

to  more 

A  significant  achievement  for  2012  was 
the  recruitment  of  over  1,000  new  team 
members, which brought our total employee 
head  count 
than  7,600.  This 
recruitment  effort  enabled  us  to  successfully 
staff our existing and newbuild rigs with the 
skilled and competent personnel required to 
maintain the exceptional caliber of our global 
workforce.  

To  reach  this  milestone,  we  significantly 
enhanced  our  recruitment  process  during 
the  year  by  leveraging  the  capability  and 
functionality  of  a  new  web-based  human 
resource information system and recruitment 
modules,  enabling  us  to  identify,  assess 
and  onboard  top  candidates  at  previously 
unattainable  speed.  Additionally,  Noble’s 
referral  program  continues  to  be  a  source 
candidates,  with  existing 
of  excellent 
employees  generating  more 
than  2,000 
referrals last year.

the 

One  of 

significant 

challenges 
facing  Noble  and  our  industry  is  the  hiring, 
development  and  retention  of  top-flight 
team  members.  The  drivers  of  this  challenge 
are  two-fold.  First,  there 
is  the  coming 
exodus  from  the  industry  of  longer-served 

to 

As  we 

continue 

reinforce  our 
commitment  to  employee  development  by 
providing opportunities for advancement, we 
have  also  seen  our  offshore  employee 
attrition  rate  continue  to  decline  for  the 
third consecutive year. We believe the brand 
loyalty  we  enjoy  with  our  teammates  is 

among  the  best  in  our  industry  and  in  the 
current  environment  this  is  something  of 
which we can all be proud.

Once  a  new  employee  joins  Noble,  our 
goal  is  to  ensure  that  the  team  member 
begins  a  steady  and  deliberate  training  and 
development  process 
that  will  continue 
throughout  that  individual’s  Noble  career. 
In  2012,  Noble  continued  its  increase  in 
significant 
learning  and 
development for employees. Last year alone, 
our  investments  in  employee  development 
increased by more than 27 percent over 2011, 
setting a new record for the Company.

state-of-the-art 

We  also  made 

significant  progress 
toward  the  completion  of  our  U.S.-based 
Offshore  Operations  Training  Center,  which 
will  open  in  mid-2013.  This  facility  will 
house 
computer-based 
simulation  environments  for  drilling,  well 
control,  dynamic  positioning,  stability  and 
ballast  control,  power  management,  crane 
operations  and  emergency  management.  
The  technology  being  built  into  this  facility 
mirrors  the  technology  in  our  new  fleet  and 
will  provide  the  best  learning,  competency 
development,  and  assessment  environment 
in  the  industry.  The  Center  will  be  home  for 
training  new  employees  in  the  Noble  way 
of  working  and  for  continuing  education, 
learning  and  competency  assessment  for  rig 
crews throughout their careers.  

Noble  also  is  adding  drilling  and  crane 
simulators  in  Brazil,  Korea  and  Singapore  to 
support the ramp-up of our expanding cyber-
based  fleet.  In  addition  to  the  simulation

Together,  these  efforts  and  investments  in

to  deliver  the  safest,  most  efficient  offshore 
drilling operations possible.

As  we  enter  this  next  chapter  of  our 
history,  Noble  is  more  than  just  a  company 
with a nine decade-long heritage. It’s a great 
company  with  staying  power,  flexibility  and 
a commitment to operational excellence. It is 
also a company that we believe is on a course 
to  deliver  excellent  service  to  our  customers 
and real value for our shareholders. On both 
points,  Noble  is  positioned  for  a  promising 
future,  one  that  we  are  defining  today 
through  our  outstanding  workforce,  fleet

Noble  has 

long  had  a  worldwide 
customer  base,  however,  we  enter  2013 
truly operating on a global basis. Geographic 
efforts  in  our  marketing  program  have  been 
expanded  and  our  operating  portfolio  now 
includes the Asia Pacific region, Australia and 
Alaska.  More  resources  will  be  added  to  this 
effort  as  we  continue  to  gain  scale  in  these 
important drilling venues.

than 

At  the  risk  of  making  it  sound  as  though 
the  path  we  have  chosen  has  been  free 
from  bumps,  it  has  not.  During  2012  we 
acceptable 
experienced 
greater 
operational  downtime,  diminishing 
the 
impact  of  our  strategic  efforts.  I  can  assure 
you  that  increasing  uptime  has  our  full 
attention.  A  major  company-wide  initiative 
has been launched to attack the root  causes 
of  downtime.  Known  internally  as  “SUPER” 
(Subsea  Uptime  Performance  –  Enhanced 
Reliability),  this  program  requires,  among 
other  things,  unwavering  compliance  to 
Noble  Subsea  Standards  and  Well  Control 
Policy,  strict  adherence  to  our  end-of-well 
preventative  maintenance 
procedures 
and  quality  oversight,  and  assurance  of 
maintenance  and  repairs  on  all  subsea 
control systems and associated equipment. 

The  SUPER 

initiative  will  support  the 
efforts of that team by setting company-wide 
standards for managing these assets. Solving 
the issue of excess downtime won’t be easy, 
but  Noble  has  committed  the  resources 
needed  to  dramatically  impact  this  situation 
going  forward.  From  better  training  for  our 
teams to setting higher standards for support 
and  quality  from  our  suppliers,  we  will  not 
rest until we improve our uptime.

Item  1. 
General  

Business.  

Noble Corporation, a Swiss corporation, is a leading offshore drilling contractor for the oil and gas industry. We perform 
contract drilling services with our fleet of 79 mobile offshore drilling units located worldwide. We also own one floating production 
storage and offloading unit. Our fleet consists of 14 semisubmersibles, 14 drillships, 49 jackups and two submersibles, including 11 
units under construction as follows:  

• 

• 

five dynamically positioned, ultra-deepwater, harsh environment drillships and  
six high-specification, heavy-duty, harsh environment jackups.  

For additional information on the specifications of our fleet, see “Item 2. Properties.—Drilling Fleet.” As of February 7, 
2013, approximately 85 percent of our fleet was located outside the United States in the following areas: Mexico, Brazil, the North 
Sea,  the  Mediterranean,  West  Africa,  the  Middle  East,  India  and  Australia.  Noble  and  its  predecessors  have  been  engaged  in  the 
contract drilling of oil and gas wells since 1921.  

Business Strategy  

Our goal is to be the preferred offshore drilling contractor for the oil and gas industry based upon the following overriding 

principles:  

• 

• 

• 

operate in a manner that provides a safe working environment for our employees while protecting the environment and 
our assets;  
provide an attractive investment vehicle for our shareholders; and  
deliver  exceptional  customer  service  through  a  large,  diverse  and  technically  advanced  fleet  operated  by  competent 
personnel.  

We have actively expanded our offshore drilling and deepwater capabilities in recent years through the construction and 
acquisition of rigs. As part of this technical and operational expansion, we plan to continue pursuing opportunities to upgrade our fleet 
to achieve greater technological capability, which we believe will lead to increased drilling efficiencies and the ability to complete the 
increasingly more complex well programs required by our customers.  

Our business strategy also focuses on the active expansion of our worldwide deepwater capabilities through upgrades and 
modifications, acquisitions and divestitures of our standard specification drilling units, as well as the deployment of our drilling assets 
in important oil and gas producing areas throughout the world. 

During 2012, we continued our newbuild program with the following 14 projects:  

•  we commenced operations on three dynamically positioned ultra-deepwater, harsh environment drillships: two Bully-class 
drillships  currently  operating  in  the  U.S.  Gulf  of  Mexico  and  Brazil,  respectively,  and  one  Globetrotter-class  drillship 
currently operating in the U.S. Gulf of Mexico;  

•  we  continued  construction  on  one  dynamically  positioned,  ultra-deepwater,  harsh  environment  Globetrotter-class 

drillship, which is scheduled to be delivered to our customer in the fourth quarter of 2013;  

•  we  continued  construction  on  four  dynamically  positioned,  ultra-deepwater,  harsh  environment  drillships  at  Hyundai 
Heavy Industries Co. Ltd., the first of which is estimated to be delivered from the shipyard in the second quarter of 2013; 
and  

•  we  continued  construction  on  six  high-specification,  heavy  duty,  harsh  environment  jackups,  the  first  of  which  is 

estimated to be delivered from the shipyard in the second quarter of 2013.  

Capital expenditures, including expenditures related to the items noted above, totaled $1.7 billion during 2012.  

As part of our ongoing strategic planning process, we review our fleet and the strategic benefits of our drilling rigs. As 
part of this process, we continue to analyze potential divestment of certain of our standard specification units and related assets in one 
or more transactions. These dispositions may include sales of assets to third parties, a spin-off, or other distribution or separation of 
assets or a combination of such transactions. In analyzing our disposition alternatives, we consider the strategic benefit to our ongoing 
operations while seeking to secure what we consider appropriate value for our shareholders. While we may continue to operate some 
or  all  standard  specification  drilling  rigs,  we  have  taken  certain  preliminary  steps  to  put  ourselves  in  a  better  position  to  pursue  a 
potential  spin-off  and/or  sale  should  we  decide  to  do  so.  These  include  analyzing  the  internal  restructuring  steps  necessary  for  a 

1 

 
potential  spin-off  or  sale  and  related  tax  considerations,  seeking  certain  preparatory  tax  rulings  and  commencing  preparation  of 
financial  statements  for  a  potential  separate  group  that  could  be  spun  off  or  sold.  We  have  not  completed  the  preliminary  work  to 
effect,  nor  has  our  board  of  directors  approved,  any  such  transactions.  We  make  no  assurance  that  we  will  ultimately  undertake  or 
consummate any sale, spin-off or separation transactions involving our standard specification assets.  

We have entered into an agreement to sell our jackup, the  Noble Lewis Dugger, to a third party that owns and operates 
supply  vessels,  platform  drilling  rigs  and  jackups  in  Mexico. This  unit  is  being  sold  for  $61  million  and  the  closing  is  expected  to 
occur in the second quarter of 2013 after the unit has completed its contract with its current customer. The transaction is subject to 
customary closing conditions. We had entered into an agreement to sell the Noble Don Walker for $18 million. The buyer was unable 
to close the transaction, although we remain in discussions to potentially extend the sale agreement. The unit has been cold-stacked in 
Cameroon since 2009.  

Demand for our services is a function of the worldwide supply of mobile offshore drilling units. Industry analysts widely 
acknowledge that a significant expansion of industry supply of both jackups and ultra-deepwater units has commenced, the majority of 
which currently have no contract. The introduction of non-contracted rigs into the marketplace will increase the supply of rigs which 
compete for drilling service contracts, which could negatively impact the dayrates we are able to achieve. Our strategy on newbuild 
construction has generally been to expand our drilling fleet in connection with a long-term drilling contract that covers a substantial 
portion of our capital investment and provides an acceptable return on our capital employed. However, in response to the addition of a 
significant number of new, technologically advanced units in the global fleet and changes in customer requirements and preferences, 
we  believe  that  in  order  to  maintain  long-term  competitiveness,  it  has  become  both  necessary  and  desirable  for  us  to  engage  in 
building speculative highly advanced jackups and floating units. Of the units we currently have under construction, two of the ultra-
deepwater drillships and two of the heavy-duty, harsh environment jackups are being constructed without customer contracts. We will 
attempt  to secure contracts  for these  units prior to their completion. We  may continue  speculative building, even in the absence of 
contracts for our units already under construction.  

From time to time, we evaluate individual rig transactions and business combinations with other parties where we believe 
we can create shareholder value. We will continue to consider business opportunities that promote our growth strategy and optimize 
shareholder value.  

In  previous  years,  the  drilling  industry  has  experienced  significant  increases  in  dayrates  for  drilling  services  in  most 
markets,  coupled  with  higher  demand  for  drilling  equipment  and  shortages  of  personnel.  This  environment  drove  operating  costs 
higher and magnified the importance of recruiting, training and retaining skilled personnel. While there continues to be instability in 
the global financial markets we believe the current market offers limited supply and high demand for both our drilling units and the 
pool of qualified labor to operate our rigs.  

In  recognition  of  the  importance  of  our  offshore  operations  personnel  in  achieving  a  safety  record  that  has  historically 
outperformed  the  offshore  drilling  industry  sector  and  to  retain  such  personnel,  we  have  implemented  a  number  of  key  operations 
personnel  retention  programs.  We  believe  these  programs  are  necessary  to  complement  our  other  short  and  long-term  incentive 
programs to attract and retain the skilled personnel we need to maintain safe and efficient operations.  

Drilling Contracts  

We typically employ each drilling unit under an individual contract. Although the final terms of the contracts result from 
negotiations  with  our  customers,  many  contracts  are  awarded  based  upon  a  competitive  bidding  process.  Our  drilling  contracts 
generally contain the following terms:  

• 

• 

• 

• 

• 

• 

contract duration extending over a specific period of time or a period necessary to drill a defined number wells;  
provisions  permitting  early  termination  of  the  contract  by  the  customer  (i) if  the  unit  is  lost  or  destroyed  or  (ii) if 
operations are suspended for a specified period of time due to breakdown of equipment;  
provisions  allowing  the  impacted  party  to  terminate  the  contract  if  specified  “force  majeure”  events  beyond  the 
contracting parties’ control occur for a defined period of time;  
payment  of  compensation  to  us  (generally  in  U.S.  Dollars  although  some  customers,  typically  national  oil  companies, 
require a part of the compensation to be paid in local currency) on a “daywork” basis, so that we receive a fixed amount 
for  each  day  (“dayrate”)  that  the  drilling  unit  is  operating  under  contract  (a  lower  rate  or  no  compensation  is  payable 
during periods of equipment breakdown and repair or adverse weather or in the event operations are interrupted by other 
conditions, some of which may be beyond our control);  
payment by us of the operating expenses of the drilling unit, including labor costs and the cost of incidental supplies; and  
provisions that allow us to recover certain cost increases from our customers in certain long-term contracts.  

2 

 
The  terms  of  some  of  our  drilling  contracts  permit  early  termination  of  the  contract  by  the  customer,  without  cause, 
generally exercisable upon advance notice to us and in some cases without requiring an early termination payment to us. Our drilling 
contracts  with  Petróleos  Mexicanos  (“Pemex”)  in  Mexico,  for  example,  allow  early  cancellation  with  30  days  or  less  notice  to  us 
without Pemex making an early termination payment.  

Generally, our contracts allow us to recover our mobilization and demobilization costs associated with moving a drilling 
unit  from  one  regional  location  to  another.  When  market  conditions  require  us  to  assume  these  costs,  our  operating  margins  are 
reduced accordingly. We cannot predict our ability to recover these costs in the future. For shorter moves, such as “field moves,” our 
customers have generally agreed to assume the costs of moving the unit by paying us a reduced dayrate or “move rate” while the unit 
is being moved.

Analysis of Financial Condition and Results of Operations – Contract Drilling Services Backlog.”  

Acquisition of Frontier Holdings Limited  

On  July 28,  2010,  Noble-Swiss  and  Noble  AM  Merger  Co.,  a  Cayman  Islands  company  and  indirect  wholly-owned 
subsidiary  of  Noble-Swiss  (“Merger  Sub”),  completed  the  acquisition  of  FDR  Holdings  Limited,  a  Cayman  Islands  company 
(“Frontier”).  The  Frontier  acquisition  was  for  a  purchase  price  of  approximately  $1.7  billion  in  cash  plus  liabilities  assumed.  The 
acquisition  strategically  expanded  and  enhanced  our  global  fleet.  Frontier’s  results  of  operations  were  included  in  our  results 
beginning July 28, 2010.  

Offshore Drilling Operations  

Contract Drilling Services  

We conduct offshore contract drilling operations, which accounted for over 97 percent of our operating revenues for the 
years ended December 31, 2012, 2011 and 2010. We conduct our contract drilling operations principally in the U.S. Gulf of Mexico 
and  Alaska,  Mexico,  Brazil,  the  North  Sea,  the  Mediterranean,  West  Africa,  the  Middle  East,  India  and  Australia.  Revenues  from 
Royal Dutch Shell, PLC (“Shell”) and its affiliates accounted for approximately 32 percent, 24 percent and 12 percent of our total 
operating  revenues  in  2012,  2011  and  2010,  respectively.  Revenues  from  Petróleo  Brasileiro  S.A.  (“Petrobras”)  accounted  for 
approximately 14 percent, 18 percent and 19 percent of our total operating revenues in 2012, 2011 and 2010, respectively. Pemex did 
not account for more than 10 percent of our total operating revenues in 2012. Revenues from Pemex accounted for approximately 15 
percent and 20 percent of our total operating revenues in 2011 and 2010, respectively. No other single customer accounted for more 
than 10 percent of our total operating revenues in 2012, 2011 or 2010.  

Labor Contracts  

We perform services for drilling and workover activities covering two platforms off the east coast of Canada; this contract 
extends through April 2013. We do not own or lease these platforms. Under our labor contracts, we provide the personnel necessary to 
manage and perform the drilling operations from a drilling platform owned by the operator.  

During 2011, we commenced a refurbishment project with our customer, Shell, for one of its rigs. Under the contract, we 
provided the management and oversight of the project, as well as the personnel necessary to complete the refurbishment. During 2012, 
the construction phase of the project was completed and the rig began operating off the coast of Alaska. As with the Canadian labor 
contract noted above, we provide labor personnel and management services on the project but do not own or lease the related rig.  

Competition  

The  offshore  contract  drilling  industry  is  a  highly  competitive  and  cyclical  business  characterized  by  high  capital  and 

maintenance costs. Some of our competitors may have access to greater financial resources than we do.  

In the provision of contract drilling services, competition involves numerous factors, including price, rig availability and 
suitability, experience of the  workforce, efficiency, safety  performance record, condition and age of equipment, operating integrity, 
reputation, industry standing and client relations. We believe that we compete favorably with respect to all of these factors. We follow 
a policy of keeping our equipment well maintained and technologically competitive. However, our equipment could be made obsolete 
by the development of new techniques and equipment, regulations or customer preferences.  

We  compete  on  a  worldwide  basis,  but  competition  may  vary  by  region  at  any  particular  time.  Demand  for  offshore 
drilling equipment also depends on the exploration and development programs of oil and gas producers, which in turn are influenced 
by the financial condition of such producers, by general economic conditions, prices of oil and gas and by political considerations and 
policies.  

3 

 
In  addition,  industry-wide  shortages  of  supplies,  services,  skilled  personnel  and  equipment  necessary  to  conduct  our 
business have  historically occurred. We cannot assure that  any such shortages experienced in the past  will  not happen again in the 
future.  

Governmental Regulations and Environmental Matters  

Political  developments  and  numerous  governmental  regulations,  which  may  relate  directly  or  indirectly  to  the  contract 
drilling industry, affect many aspects of our operations. Our contract drilling operations are subject to various laws and regulations in 
countries in which we operate, including laws and regulations relating to the equipping and operation of drilling units, the reduction of 
greenhouse gas emissions to address climate change, currency conversions and repatriation, oil and gas exploration and development, 
taxation of offshore earnings and earnings of expatriate personnel and use of local employees and suppliers by foreign contractors. A 
number of countries actively regulate and control the ownership of concessions and companies holding concessions, the exportation of 
oil and gas and other aspects of the oil and gas industries in their countries. In addition, government action, including initiatives by the 
Organization  of  Petroleum  Exporting  Countries  (“OPEC”),  may  continue  to  contribute  to  oil  price  volatility.  In  some  areas  of  the 
world,  this  governmental  activity  has  adversely  affected  the  amount  of  exploration  and  development  work  done  by  oil  and  gas 
companies and their need for drilling services, and likely will continue to do so.  

The  regulations  applicable  to  our  operations  include  provisions  that  regulate  the  discharge  of  materials  into  the 
environment or require remediation of contamination under certain circumstances. Many of the countries in whose waters we operate 
from time to time regulate the discharge of oil and other contaminants in connection with drilling operations. Failure to comply with 
these  laws  and  regulations,  or  failure  to  obtain  or  comply  with  permits,  may  result  in  the  assessment  of  administrative,  civil  and 
criminal penalties, imposition of remedial requirements and the imposition of injunctions to force future compliance. We have made, 
and will continue to make, expenditures to comply with environmental requirements. To date we have not expended material amounts 
in order to comply, and we do not believe that our compliance with such requirements will have a material adverse effect upon our 
results of operations or competitive position or materially increase our capital expenditures. Although these requirements impact the 
energy  and  energy  services  industries,  generally  they  do  not  appear  to  affect  us  in  any  material  respect  that  is  different,  or  to  any 
materially greater or lesser extent, than other companies in the energy services industry. However, our business and prospects could be 
adversely  affected  by  regulatory  activity  that  prohibits  or  restricts  our  customers’  exploration  and  production  activities,  results  in 
reduced demand for our services or imposes environmental protection requirements that result in increased costs to us, our customers 
or the oil and natural gas industry in general.  

The following is a summary of some of the existing laws and regulations which apply to our operations in the U.S. Gulf of 
Mexico  to  serve  as  an  example  of  the  various  laws  and  regulations  to  which  we  are  subject.  While  laws  vary  widely  in  each 
jurisdiction, each of the laws and regulations below addresses environmental issues similar to those in most of the other jurisdictions 
in which we operate.  

Spills  and  Releases. The  Comprehensive  Environmental  Response,  Compensation,  and  Liability  Act  (“CERCLA”),  and 
similar  state  laws  and  regulations,  impose  joint  and  several  liabilities,  without  regard  to  fault  or  the  legality  of  the  original  act,  on 
certain classes of persons that contributed to the release of a “hazardous substance” into the environment. These persons include the 
“owner” and “operator” of the site where the release occurred, past owners and operators of the site, and companies that disposed or 
arranged for the disposal of the hazardous substances found at the site. Responsible parties under CERCLA may be liable for the costs 
of cleaning up hazardous substances that have been released into the environment and for damages to natural resources. In the course 
of our ordinary operations, we may generate waste that may fall within CERCLA’s definition of a “hazardous substance.” However, 
we have to date not received any notification that we are, or may be, potentially responsible for cleanup costs under CERCLA.  

Offshore  Regulation.  The  U.S.  government  has  indicated  that  before  any  recipient  of  a  deepwater  drilling  permit  may 
commence drilling, (i) the operator must demonstrate that containment resources are available promptly in the event of a deepwater 
blowout,  (ii) the  chief  executive  officer  of  the  operator  seeking  to  perform  deepwater  drilling  must  certify  that  the  operator  has 
complied with all applicable regulations and (iii) the Bureau of Ocean Energy Management (“BOEM”) and the Bureau of Safety and 
Environmental  Enforcement  (“BSEE”)  will  conduct  inspections  of  such  deepwater  drilling  operation  for  compliance  with  the 
applicable  regulations.  We  cannot  predict  when  the  applicable  government  agency  will  determine  that  any  deepwater  driller  is  in 
compliance  with  the  new  regulations.  Third  party  challenges  to  industry  operations  in  the  U.S.  Gulf  of  Mexico  may  also  serve  to 
further delay or restrict activities. Further, in 2010 and 2011, the BSEE and its predecessor agency issued initial regulations on the 
design and operation of  well  control and other equipment  at offshore production sites, implementation of  safety and  environmental 
management  systems  (“SEMS”),  and  mandatory  third-party  compliance  audits.  On  August 22,  2012,  BSEE  published  a  final  rule 
amending the regulations regarding design and operation of well control and other equipment, and a new SEMS rule was sent to the 
Office  of  Management  and  Budget  for  a  90-day  review  on  January 31,  2013.  BSEE  has  indicated  that  there  will  be  an  additional, 
separate  rulemaking  to  govern  the  design,  performance  and  maintenance  of  blowout  preventers  but  that  rule  has  not  yet  been 
published. BSEE has also published a draft statement of policy on safety culture with nine proposed characteristics of a robust safety 
culture. If the new regulations, policies, operating procedures and possibility of increased legal liability are viewed by our current or 
future customers as a significant impairment to expected profitability on projects, then they could discontinue or curtail their offshore 
operations, thereby adversely affecting our operations by limiting drilling opportunities or imposing materially increased costs.

The  Oil  Pollution  Act. The  U.S.  Oil  Pollution  Act  of  1990  (“OPA”)  and  similar  regulations  impose  certain  operational 
requirements  on  offshore  rigs  operating  in  the  U.S.  Gulf  of  Mexico  and  govern  liability  for  leaks,  spills  and  blowouts  involving 
pollutants.  The  OPA  imposes  strict,  joint  and  several  liabilities  on  “responsible  parties”  for  damages,  including  natural  resource 
damages, resulting from oil spills into or upon navigable waters, adjoining shorelines or in the exclusive economic zone of the United 
States. A “responsible party” includes the owner or operator of an onshore facility and the lessee or permittee of the area in which an 
offshore  facility  is  located.  The  OPA  establishes  a  liability  limit  for  onshore  facilities  of  $350 million,  while  the  liability  limit  for 
offshore facilities is equal to all removal costs plus up to $75 million in other damages. These liability limits may not apply if a spill is 
caused  by  a  party’s  gross  negligence  or  willful  misconduct,  if  the  spill  resulted  from  violation  of  a  federal  safety,  construction  or 
operating regulation, or if a party fails to report a spill or to cooperate fully in a clean-up.  

Regulations  under  the  OPA  require  owners  and  operators  of  rigs  in  United  States  waters  to  maintain  certain  levels  of 
financial  responsibility.  The  failure  to  comply  with  the  OPA’s  requirements  may  subject  a  responsible  party  to  civil,  criminal,  or 
administrative enforcement actions. We are not aware of any action or event that would subject us to liability under the OPA, and we 
believe that compliance with the OPA’s financial assurance and other operating requirements will not have a material impact on our 
operations or financial condition.  

Waste  Handling. The  U.S.  Resource  Conservation  and  Recovery  Act  (“RCRA”),  and  similar  state  and  local  laws  and 
regulations  govern  the  management  of  wastes,  including  the  treatment,  storage  and  disposal  of  hazardous  wastes.  RCRA  imposes 
stringent  operating  requirements,  and  liability  for  failure  to  meet  such  requirements,  on  a  person  who  is  either  a  “generator”  or 
“transporter”  of  hazardous  waste  or  an  “owner”  or  “operator”  of  a  hazardous  waste  treatment,  storage  or  disposal  facility.  RCRA 
specifically  excludes  from  the  definition  of  hazardous  waste  drilling  fluids,  produced  waters,  and  other  wastes  associated  with  the 
exploration,  development,  or  production  of  crude  oil  and  natural  gas.  A  similar  exemption  is  contained  in  many  of  the  state 
counterparts to RCRA. As a result, we are not required to comply with a substantial portion of RCRA’s requirements as our operations 
generate  minimal  quantities  of  hazardous  wastes.  However,  these  wastes  may  be  regulated  by  the  United  States  Environmental 
Protection  Agency  (“EPA”)  or  state  agencies  as  solid  waste.  In  addition,  ordinary  industrial  wastes,  such  as  paint  wastes,  waste 
solvents,  laboratory  wastes,  and  waste  compressor  oils  may  be  regulated  under  RCRA  as  hazardous  waste.  We  do  not  believe  the 
current costs of  managing our  wastes, as they are presently classified, to be significant. However, a  petition is currently before the 
EPA to revoke the oil and natural gas exploration and production exemption. Any repeal or modification of this or similar exemption 
in similar state statutes, would increase the volume of hazardous waste we are required to manage and dispose of, and would cause us, 
as well as our competitors, to incur increased operating expenses with respect to our U.S. operations.  

Water Discharges. The U.S. Federal Water Pollution Control Act of 1972, as amended, also known as the “Clean Water 
Act,”  and  similar  state  laws  and  regulations  impose  restrictions  and  controls  on  the  discharge  of  pollutants  into  federal  and  state 
waters. These laws also regulate the discharge of storm water in process areas. Pursuant to these laws and regulations, we are required 
to obtain and maintain approvals or permits for the discharge of wastewater and storm water. We do not anticipate that compliance 
with these laws will cause a material impact on our operations or financial condition.  

Air  Emissions. The  U.S.  Federal  Clean  Air  Act  and  associated  state  laws  and  regulations  restrict  the  emission  of  air 
pollutants  from  many  sources,  including  oil  and  natural  gas  operations.  New  facilities  may  be  required  to  obtain  permits  before 
operations  can  commence,  and  existing  facilities  may  be  required  to  obtain  additional  permits,  and  incur  capital  costs,  in  order  to 
remain  in  compliance.  Federal  and  state  regulatory  agencies  can  impose  administrative,  civil  and  criminal  penalties  for  non-
compliance  with  air  permits  or  other  requirements  of  the  Clean  Air  Act  and  associated  state  laws  and  regulations.  In  general,  we 
believe  that  compliance  with  the  Clean  Air  Act  and  similar  state  laws  and  regulations  will  not  have  a  material  impact  on  our 
operations or financial condition.  

Climate  Change. There  is  increasing  attention  concerning  the  issue  of  climate  change  and  the  effect  of  greenhouse  gas 
(“GHG”)  emissions.  In  December  2009,  the  EPA  determined  that  current  and  projected  concentrations  of  six  key  GHG’s  in  the 
atmosphere threaten public health and welfare. The EPA subsequently finalized GHG standards for motor vehicles, the effect of which 
could reduce demand for motor fuels refined from crude oil, and a final rule to address permitting of GHG emissions from stationary 
sources under the Clean Air Act’s Prevention of Significant Deterioration (“PSD”) and Title V permitting programs, which require the 
use of “best available control technology” for GHG emissions from new and modified major stationary sources, which can sometimes 
include  drillships.  EPA  regulations  known  as  the  “Tailoring  Rule”  also  require  the  PSD  program  to  address  GHG  emissions  from 
relatively  smaller  stationary  sources  in  the  future.  The  EPA  has  also  adopted  rules  requiring  the  monitoring  and  reporting  of  GHG 
emissions from specified sources in the United States, including, among other things, certain onshore and offshore oil and natural gas 
production facilities, on an annual basis. Facilities containing petroleum and natural gas systems that emit 25,000 metric tons or more 
of CO2 equivalent per year are now required to report annual GHG emissions to the EPA.

Further, proposed legislation has been introduced in Congress that would establish an economy-wide cap on emissions of 
GHG’s in the United States and would require most sources of GHG emissions to obtain GHG emission “allowances” corresponding 
to their annual emissions of GHG’s. Moreover, in 2005, the Kyoto Protocol to the 1992 United Nations Framework Convention on 
Climate Change, which establishes a binding set of emission targets for greenhouse gases, became binding on all countries that had 
ratified  it.  Recent  international  discussions  following  the  United  Nations  Climate  Change  Conference  in  Doha,  Qatar  in  December 
2012  are  exploring  options  to  replace  the  Kyoto  Protocol.  While  it  is  not  possible  at  this  time  to  predict  how  new  treaties  and 
legislation that may be enacted to address GHG emissions would impact our business, the modification of existing laws or regulations 
or  the  adoption  of  new  laws  or  regulations  curtailing  exploratory  or  developmental  drilling  for  oil  and  gas  could  materially  and 
adversely  affect  our  operations  by  limiting  drilling  opportunities  or  imposing  materially  increased  costs.  Moreover,  incentives  to 
conserve  energy  or  use  alternative  energy  sources  could  have  a  negative  impact  on  our  business  if  such  incentives  reduce  the 
worldwide demand for oil and gas.  

Safety. The  U.S.  Occupational  Safety  and  Health  Act  (“OSHA”)  and  other  similar  laws  and  regulations  govern  the 
protection  of  the  health  and  safety  of  employees.  The  OSHA  hazard  communication  standard,  EPA  community  right-to-know 
regulations  under  Title III  of  CERCLA  and  similar  state  statutes  require  that  information  be  maintained  about  hazardous  materials 
used or produced in our operations and that this information be provided to employees, state and local governments and citizens. We 
believe that we are in substantial compliance with these requirements and with other applicable OSHA requirements.  

Insurance and Indemnification Matters  

Our operations are subject to many hazards inherent in the drilling business, including blowouts, fires and collisions or 
groundings of offshore equipment, and damage or loss from adverse weather and sea conditions. These hazards could cause personal 
injury or loss of life, loss of revenues, pollution and other environmental damage, damage to or destruction of property and equipment 
and oil and natural gas producing formations, and could result in claims by employees, customers or third parties.  

Our drilling contracts provide for varying levels of indemnification from our customers and in most cases also require us 
to indemnify our customers for certain losses. Under our drilling contracts, liability with respect to personnel and property is typically 
assigned  on  a  “knock-for-knock”  basis,  which  means  that  we  and  our  customers  assume  liability  for  our  respective  personnel  and 
property,  irrespective  of  the  fault  or  negligence  of  the  party  indemnified.  In  addition,  our  customers  may  indemnify  us  in  certain 
instances for damage to our down-hole equipment and, in some cases, our subsea equipment.  

Our  customers  typically  assume  responsibility  for  and  indemnify  us  from  loss  or  liability  resulting  from  pollution  or 
contamination, including third-party damages and clean-up and removal, arising  from  operations under the contract and originating 
below the surface of the water. We are generally responsible for pollution originating above the surface of the water and emanating 
from our drilling units. Additionally, our customers typically indemnify us for liabilities incurred as a result of a blow-out or cratering 
of the well and underground reservoir loss or damage.  

In  addition  to  the  contractual  indemnities  described  above,  we  also  carry  protection  and  indemnity  (“P&I”)  insurance, 
which is a comprehensive general liability insurance program covering liability resulting from offshore operations. Our P&I insurance 
includes coverage for liability resulting from personal injury or death of third parties and our offshore employees, third party property 
damage,  pollution,  spill  clean-up  and  containment  and  removal  of  wrecks  or  debris.  Our  insurance  policy  does  not  exclude  losses 
resulting from our gross negligence or willful misconduct. Our P&I insurance program is renewed in March of each year and currently 
has a standard deductible of $10 million per occurrence, with maximum liability coverage of $750 million.  

Our insurance policies and contractual rights to indemnity may not adequately cover our losses and liabilities in all cases. 
For additional information, please read “We may have difficulty obtaining or maintaining insurance in the future and our insurance 
coverage and contractual indemnity rights may not protect us against all of the risks and hazards we face” included in Item 1A of this 
Annual Report on Form 10-K.  

The  above  description  of  our  insurance  program  and  the  indemnification  provisions  of  our  drilling  contracts  is  only  a 
summary as of the time of preparation of this report, and is general in  nature. Our insurance program and the terms of our drilling 
contracts  may change  in the  future. In addition, the indemnification provisions of our drilling contracts  may be subject to differing 
interpretations, and enforcement of those provisions may be limited by public policy and other considerations.  

Employees  

At December 31, 2012, we had approximately 5,600 employees, excluding approximately 2,000 persons engaged through 
labor contractors or agencies. Approximately 75 percent of our employees were engaged in operations outside of the U.S. We are not a 
party to any material collective bargaining agreements, and we consider our employee relations to be satisfactory.

Item 1A. 

Risk Factors.  

You  should  carefully  consider  the  following  risk  factors  in  addition  to  the  other  information  included  in  this  Annual 
Report on Form 10-K. Each of these risk factors could affect our business, operating results and financial condition, as well as affect 
an investment in our shares.  

Risk Factors Relating to Our Business  

Our business depends on the level of activity in the oil and gas industry, which is significantly affected by volatile oil 

and gas prices.  

Demand for drilling services depends on a variety of economic and political factors and the level of activity in offshore oil 
and  gas  exploration  and  development  and  production  markets  worldwide.  Commodity  prices,  and  market  expectations  of  potential 
changes  in  these  prices,  may  significantly  affect  this  level  of  activity.  However,  higher  prices  do  not  necessarily  translate  into 
increased drilling activity since our clients’ expectations of future commodity prices typically drive demand for our rigs. Oil and gas 
prices are extremely volatile and are affected by numerous factors beyond our control, including:  

• 

• 

laws  and  regulations  related  to  environmental  or  energy  security  matters,  including  those  addressing  alternative  energy 
sources and the risks of global climate change;  
the  political  environment  of  oil-producing  regions,  including  uncertainty  or  instability  resulting  from  civil  disorder,  an 
outbreak or escalation of armed hostilities or acts of war or terrorism;  

•  worldwide demand for oil and gas, which is impacted by changes in the rate of economic growth in the global economy;  
• 

the ability of OPEC to set and maintain production levels and pricing;  
the level of production in non-OPEC countries;  
the  laws  and  regulations  of  governments  regarding  exploration  and  development  of  their  oil  and  gas  reserves  or 
speculation regarding future laws or regulations;  
the cost of exploring for, developing, producing and delivering oil and gas;  
the discovery rate of new oil and gas reserves;  
the rate of decline of existing and new oil and gas reserves;  

• 

• 

• 

• 

• 

7 

 
• 

• 

• 

• 

• 

• 

• 

available pipeline and other oil and gas transportation capacity;  
the ability of oil and gas companies to raise capital;  
adverse weather conditions (such as hurricanes and monsoons) and seas;  
the development and exploitation of alternative fuels;  
tax laws, regulations and policies;  
advances in exploration, development and production technology; and  
the availability of, and access to, suitable locations from which our customers can produce hydrocarbons.  

Demand for our drilling services may decrease due to events beyond our control and some of our customers could seek 

to cancel, terminate or renegotiate their contracts.  

Our business could be impacted by events beyond our control including changes in our customers’ drilling programs or 
budgets or their liquidity (including access to capital), changes in, or prolonged reductions of, prices for oil and gas, or shifts in the 
relative strength of various geographic drilling markets brought on by economic slowdown, or regional or worldwide recession, any of 
which  could  result  in  deterioration  in  demand  for  our  drilling  services.  In  addition,  our  customers  may  cancel  drilling  contracts  or 
letter agreements or letters of intent for drilling contracts, or exercise early termination rights found in some of our drilling contracts or 
available  under local law, for a variety of reasons,  many of  which are beyond our control. Depending upon  market conditions, our 
customers  may  also  seek  renegotiation  of  firm  drilling  contracts  to  reduce  their  obligations.  If  the  level  of  demand  for  our  drilling 
services or conditions in the offshore contract drilling industry declines, our financial position, results of operations and cash flows 
could be adversely affected.  

We may not be able to renew or replace expiring contracts or obtain contracts for our uncontracted newbuilds.  

We have a number of customer contracts that will expire in 2013 and 2014. Our ability to renew these contracts or obtain 
new contracts and the terms of any such contracts will depend on market conditions and our customers. Also, of the units we currently 
have  under  construction  as  part  of  our  newbuild  program,  two  of  the  ultra-deepwater  drillships  and  two  of  the  heavy-duty,  harsh 
environment  jackups  are  being  constructed  without  customer  contracts.  We  will  attempt  to  secure  contracts  for  these  units  prior  to 
their  completion.  We  may  be  unable  to  renew  our  expiring  contracts  or  obtain  new  contracts  for  our  newbuilds  or  the  rigs  under 
contracts that have expired or been terminated, and the dayrates under any new contracts may be below, perhaps substantially below, 
the  existing  dayrates,  which  could  have  a  material  adverse  effect  on  our  results  of  operations  and  cash  flows.  We  may  continue 
speculative building, even in the absence of contracts for our units already under construction.  

Our global operations involve additional risks.  

We operate in various regions throughout the world that may expose us to political and other uncertainties, including risks 

of:  

• 

• 

terrorist acts, war, revolution and civil disturbances;  
seizure, nationalization or expropriation of property or equipment;  

•  monetary  policies,  government  debt  downgrades  and  potential  defaults,  and  foreign  currency  fluctuations  and 

devaluations;  
the inability to repatriate income or capital;  
complications associated with repairing and replacing equipment in remote locations;  
piracy;  
import-export quotas, wage and price controls, imposition of trade barriers and other forms of government regulation and 
economic conditions that are beyond our control;  
regulatory or financial requirements to comply with foreign bureaucratic actions; and  
changing taxation policies.  

• 

• 

• 

• 

• 

• 

Our  operations  are  subject  to  various  laws  and  regulations  in  countries  in  which  we  operate,  including  laws  and 

regulations relating to:  

• 

• 

• 

the importing, exporting, equipping and operation of drilling units;  
repatriation of foreign earnings;  
currency exchange controls;  

8 

 
• 

• 

• 

oil and gas exploration and development;  
taxation of offshore earnings and earnings of expatriate personnel; and  
use and compensation of local employees and suppliers by foreign contractors.  

Our  ability  to  do  business  in  a  number  of  jurisdictions  is  subject  to  maintaining  required  licenses  and  permits  and 
complying  with  applicable  laws  and  regulations.  For  example,  as  of  December 31,  2012,  our  two  rigs  operating  in  Nigeria  were 
operating under temporary import permits and the Department of Petroleum Resources had not yet issued our Nigerian subsidiary a 
permit to operate as an oil industry service company or licenses to operate the two rigs for the year 2013. It is customary in Nigeria 
that permits and licenses are issued well into the year to which they pertain and, to date, we have been successful in obtaining new, or 
extending existing, temporary import permits and other permits and licenses. However, there can be no assurance that we will be able 
to obtain new permits or further extensions of permits necessary to continue the operation of our rigs in Nigeria. If we cannot obtain a 
new permit or an extension necessary to continue operations of any rig, we may need to cease operations under the drilling contract 
for such rig and relocate such rig from Nigerian waters. We cannot predict what impact these events may have on any such contract or 
our business in Nigeria, and we could face additional fines and sanctions in Nigeria. Furthermore, we cannot predict what changes, if 
any, relating to temporary import permit policies and procedures may be established or implemented in Nigeria in the future, or how 
any  such  changes  may  impact  our  business  there.  For  additional  information  regarding  our  completed  internal  investigation  of  our 
Nigerian  operations  and  the  status  of  our  temporary  import  permits  in  Nigeria,  see  “Part  II  Item 8.  Financial  Statements  and 
Supplementary Data, Note 16 — Commitments and Contingencies.” Changes in, compliance with, or our failure to comply with the 
laws and regulations of the countries where we operate, including Nigeria, may negatively impact our operations in those countries 
and could have a material adverse effect on our results of operations.  

In 2010 the Nigerian Oil and Gas Industry Content Development Bill was signed into law. The law is designed to create 
Nigerian content in operations and transactions within the Nigerian oil and gas industry. The law sets forth certain requirements for 
asset ownership and the utilization of Nigerian human resources and goods and services in oil and gas projects and creates a Nigerian 
Content  Development  and  Monitoring  Board  to  implement  and  monitor  the  law  and  develop  regulations  pursuant  to  the  law.  The 
Nigerian Content Development and Monitoring Board has indicated that it will require all non-Nigerian offshore drilling companies to 
reorganize their local operations to include Nigerian indigenous minority interests in the operating assets and to obtain the approval of 
the  Nigerian  Content  Development  and  Monitoring  Board  for  future  work  in  Nigeria.  The  law  also  establishes  a  Nigerian  Content 
Development Fund to fund the implementation of the law, and requires that 1 percent of the value of every contract awarded in the 
Nigerian oil and gas industry be paid into the fund. We continue to closely monitor the implementation of the law and we are in the 
process of reviewing our structural and strategic alternatives and the associated cost as  the law continues to be applied. We cannot 
predict what impact the law will ultimately have on the drilling industry and our future operations in Nigeria, but the effect on our 
operations and profitability in the region could be significant.  

In addition, other governmental actions, including initiatives by OPEC, may continue to cause oil price volatility. In some 
areas of the world, this governmental activity has adversely affected the amount of exploration and development work done by major 
oil companies, which may continue. In addition, some governments favor or effectively require the awarding of drilling contracts to 
local  contractors,  require  use  of  a  local  agent  or  require  foreign  contractors  to  employ  citizens  of,  or  purchase  supplies  from,  a 
particular jurisdiction. These practices may adversely affect our ability to compete and our results of operations.  

The U.S. government’s regulations and permitting process could have a prolonged and material adverse impact on our 

U.S. Gulf of Mexico operations.  

Subsequent to the April 2010 fire and explosion on the Deepwater Horizon, a competitor’s drilling rig in the U.S. Gulf of 
Mexico,  U.S.  governmental  authorities  implemented  a  moratorium  on  and  suspension  of  specified  types  of  drilling  activities  in  the 
U.S. Gulf of Mexico. In October 2010, the U.S. government lifted the moratorium following adoption of new regulations including a 
drilling  safety  rule  and  a  workplace  safety  rule,  each  of  which  imposed  multiple  obligations  relating  to  offshore  drilling 
operations. These  obligations  relate  to,  among  other  things;  additional  certifications  and  verifications  relating  to  compliance  with 
applicable  regulations,  compatibility  of  blowout  preventers  with  drilling  rigs  and  well  design,  third-party  inspections  and  design 
review  of  blowout  preventers,  testing  of  casing  installations,  minimum  requirements  for  personnel  operating  blowout  preventers, 
training  in  deepwater  well  control  and  mandates  of  maintenance  inspections. BSEE’s  predecessor  agency  also  proposed  to  further 
strengthen these regulations in September 2011. These additional regulations led to additional costs and increased downtime in our 
U.S. Gulf of Mexico fleet.  

The U.S. government mandated that before beginning a well in the U.S. Gulf of Mexico an operator must: (i) demonstrate 
that  containment  resources  are  available  promptly  in  the  event  of  a  deepwater  blowout,  (ii) have  the  chief  executive  officer  of  the 
operator  seeking  to  perform  deepwater  drilling  certify  that  the  operator  has  complied  with  all  applicable  regulations  and  (iii) allow 
BSEE to conduct inspections of such deepwater drilling operation for compliance with the applicable regulations. Our customers and 
other operators struggled to implement these new regulations, which resulted in increased downtime and decreased rates for a number 
of  our  contracted  units  when  these  regulations  were  instituted. While  it  appears  that  operators  have  become  accustomed  to  these 

9 

 
regulations, we cannot predict whether the permitting will continue at the current rate. Increased costs for our customers’ operations 
and permitting delays could negatively impact their planned or future exploration and development activities,  which  could result in 
reduced demand for our services.  

Governmental laws and regulations, including environmental laws and regulations, may add to our costs or limit our 

drilling activity.  

Our business is affected by public policy and laws and regulations relating to the energy industry and the environment in 

the geographic areas where we operate.  

The drilling industry is dependent on demand for services from the oil and gas exploration and production industry, and 
accordingly, we are directly affected by the adoption of laws and regulations that for economic, environmental or other policy reasons 
curtail exploration and development drilling for oil and gas. We may be required to make significant capital expenditures to comply 
with governmental laws and regulations. Governments in some foreign countries are increasingly active in regulating and controlling 
the  ownership  of  concessions,  the  exploration  for  oil  and  gas,  and  other  aspects  of  the  oil  and  gas  industries.  There  is  increasing 
attention in the United States and worldwide concerning the issue of climate change and the effect of greenhouse gases.  

Our  operations  are  also  subject  to  numerous  laws  and  regulations  controlling  the  discharge  of  materials  into  the 
environment  or  otherwise  relating  to  the  protection  of  the  environment.  The  modification  of  existing  laws  or  regulations  or  the 
adoption  of  new  laws  or  regulations  that  result  in  the  curtailment  of  exploratory  or  developmental  drilling  for  oil  and  gas  could 
materially and adversely affect our operations by limiting drilling opportunities or imposing materially increased costs. As a result, the 
application of these laws could have a material adverse effect on our results of operations by increasing our cost of doing business, 
discouraging  our  customers  from  drilling  for  hydrocarbons  or  subjecting  us  to  liability.  For  example,  we,  as  an  operator  of  mobile 
offshore drilling units in navigable U.S. waters and certain offshore areas, including the U.S. Outer Continental Shelf, are liable for 
damages and for the cost of removing oil spills for which we may be held responsible, subject to certain limitations. Our operations 
may  involve  the  use  or  handling  of  materials  that  are  classified  as  environmentally  hazardous.  Laws  and  regulations  protecting  the 
environment have generally become more stringent and in certain circumstances impose “strict liability”, rendering a person liable for 
environmental damage  without regard to negligence or fault. Environmental laws and regulations may expose us to liability for the 
conduct of or conditions caused by others or for acts that were in compliance with all applicable laws at the time they were performed.  

In November 2012, the U.S. Coast Guard in Alaska conducted an inspection of our drillship, the Noble Discoverer, and 
cited a number of deficiencies that needed to be remediated, including issues relating to the main propulsion and safety management 
system.  We  began  an  internal  investigation  in  conjunction  with  the  Coast  Guard  inspection,  and  the  Coast  Guard  began  their  own 
investigation. We reported certain potential violations of applicable law to the Coast Guard as a result of our internal investigation. 
These related to what we believe were certain unauthorized disposals of collected deck and sea water from the Noble Discoverer and 
potential record-keeping issues with the oil record books for the Noble Discoverer and other rigs. The Coast Guard has referred the 
Noble  Discoverer  matter  to  the  U.S.  Department  of  Justice  (“DOJ”)  for  further  investigation.  For  additional  information  regarding 
these  actions  relating  to  the  Alaska  investigation,  see  “Part  II,  Item 8.  Financial  Statements  and  Supplementary  Data,  Note  16— 
Commitments and Contingencies.”  

Worldwide instability in the financial and credit sectors and economic recession could have a material adverse effect 

on our financial position, results of operations and cash flows.  

Worldwide instability in the  financial and credit sectors could reduce the availability of  liquidity and credit to fund the 
continuation  and  expansion  of  industrial  business  operations  worldwide. The  shortage  of  liquidity  and  credit  combined  with 
substantial  losses  in  worldwide  equity  markets  could  lead  to  another  global  economic  recession. A  slowdown  in  economic  activity 
caused  by  a  worldwide  recession,  combined  with  lower  prices  for  oil  and  gas,  would  reduce  worldwide  demand  for  energy  and 
demand  for  drilling  services. If  demand  for  drilling  services  declines  again,  we  could  experience  a  decline  in  dayrates  for  new 
contracts and a slowing in the pace of new contract activity. Demand for our services depends on oil and natural gas industry activity 
and  expenditure  levels  that  are  directly  affected  by  trends  in  oil  and  natural  gas  prices.  Demand  for  our  services  is  particularly 
sensitive  to  the  level  of  exploration,  development,  and  production  activity  of,  and  the  corresponding  capital  spending  by,  oil  and 
natural gas companies. Any prolonged reduction in oil and natural gas prices or material impairment of our customers’ cash flow or 
liquidity,  including  their  access  to  capital,  could  result  in  lower  levels  of  exploration,  development  and  production  activity. Lower 
levels  of  exploration  activity  could  result  in  a  corresponding  decline  in  the  demand  for  our  drilling  services,  which  could  have  a 
material adverse effect on our financial position, results of operations and cash flows. The financial situation may also adversely affect 
the  ability  of  shipyards  to  meet  scheduled  deliveries  of  our  newbuilds  and  our  ability  to  renew  our  fleet  through  new  vessel 
construction projects and conversion projects.  

10 

 
We  are  substantially  dependent  on  several  of  our  customers  including  Shell  and  Petrobras,  and  the  loss  of  these 

customers could have a material adverse effect on our financial condition and results of operations.  

We  estimate  Shell  and  Petrobras  represented  approximately  61  percent  and  14  percent,  respectively,  of  our  backlog  at 
December 31, 2012 and revenues from Shell and Petrobras accounted for approximately 32 percent and 14 percent, respectively, of 
our total operating revenue for the year ended December 31, 2012. This concentration of customers increases the risks associated with 
any possible termination or nonperformance of contracts in addition to our exposure to credit risk. If either of these customers were to 
terminate or fail to perform their obligations under their contracts and we were not able to find other customers for the affected drilling 
units promptly, our financial condition and results of operations could be materially adversely affected.  

Construction, conversion or upgrades of rigs are subject to risks, including delays and cost overruns, which could have 

an adverse impact on our available cash resources and results of operations.  

We currently have multiple new construction and conversion projects underway and we may undertake additional projects 
in  the  future.  In  addition,  we  make  significant  upgrade,  refurbishment  and  repair  expenditures  to  our  fleet  from  time  to  time, 
particularly  as  our  rigs  become  older.  Some  of  these  expenditures  are  unplanned.  Our  customers  may  also  require  certain  shipyard 
reliability upgrade projects for our drillships. These projects and other efforts of this type are subject to risks of cost overruns or delays 
inherent in any large construction project as a result of numerous factors, including the following:  

shortages of equipment, materials or skilled labor;  

• 
•  work stoppages and labor disputes;  
• 

unscheduled delays in the delivery of ordered materials and equipment;  
local customs strikes or related work slowdowns that could delay importation of equipment or materials;  

• 
•  weather interferences;  
• 

difficulties in obtaining necessary permits or approvals or in meeting permit or approval conditions;  
design and engineering problems;  
inadequate regulatory support infrastructure in the local jurisdiction;  
latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions;  
unforeseen increases in the cost of equipment, labor and raw materials, particularly steel;  
unanticipated actual or purported change orders;  
client acceptance delays;  
disputes with shipyards and suppliers;  
delays in, or inability to obtain, access to funding;  
shipyard  availability,  failures  and  difficulties,  including  as  a  result  of  financial  problems  of  shipyards  or  their 
subcontractors; and  
failure or delay of third-party equipment vendors or service providers.

The failure to complete a rig upgrade or new construction on time, or the inability to complete a rig conversion or new 
construction  in  accordance  with  its  design  specifications,  may  result  in  loss  of  revenues,  penalties,  or  delay,  renegotiation  or 
cancellation  of  a  drilling  contract  or  the  recognition  of  an  asset  impairment.  Additionally,  capital  expenditures  for  rig  upgrade, 
refurbishment  and  construction  projects  could  materially  exceed  our  planned  capital  expenditures.  Moreover,  our  rigs  undergoing 
upgrade, refurbishment and repair may not earn a dayrate during the period they are out of service.  

We  could  be  adversely  affected  by  violations  of  applicable  anti-corruption  laws  and  our  failure  to  comply  with  the 

terms of our settlement agreements with the DOJ and SEC.  

We operate in a number of countries throughout the world, including countries known to have a reputation for corruption. 
We are committed to doing business in accordance with applicable anti-corruption laws and our code of business conduct and ethics. 
We are subject, however, to the risk that we, our affiliated entities or their respective officers, directors, employees and agents may 
take  action  determined  to  be  in  violation  of  such  anti-corruption  laws,  including  the  U.S.  Foreign  Corrupt  Practices  Act  of  1977 
(“FCPA”)  and  similar  laws  in  other  countries.  Any  violation  of  the  FCPA  or  other  applicable  anti-corruption  laws  could  result  in 
substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely 
affect our business, results of operations or financial condition. In addition, actual or alleged violations could damage our reputation 
and ability to do business. Further, detecting, investigating, and resolving actual or alleged violations is expensive and can consume 
significant time and attention of our senior management.  

11 

 
In 2007, we began an internal investigation of the legality under the FCPA of certain activities in Nigeria. In November 
2010, we finalized settlements of this matter with each of the SEC and the DOJ. Under the settlements with the DOJ and SEC,  we 
agreed to, among other things, pay certain fines and interest and disgorge certain profits, cooperate with the DOJ, comply  with the 
FCPA,  comply  with  certain  self-reporting  and  annual  reporting  obligations  and  comply  with  an  injunction  restraining  us  from 
violating the anti-bribery, books and records and internal controls provisions of the FCPA. Our ability to comply with the terms of the 
settlements is dependent on the success of our ongoing compliance program, including our ability to continue to manage our agents 
and supervise, train and retain competent employees, and the efforts of our employees to comply with applicable law and our code of 
business conduct and ethics.  

Also,  in  January  2011,  the  Nigerian  Economic  and  Financial  Crimes  Commission  and  the  Nigerian  Attorney  General 
Office initiated an investigation into these same activities. A subsidiary of Noble-Swiss resolved this matter through the execution of a 
non-prosecution agreement dated January 28, 2011. Pursuant to this agreement, the subsidiary paid $2.5 million to resolve all charges 
and claims of the Nigerian government.  

Any  additional  investigation  by  these  or  other  agencies  could  damage  our  reputation  and  result  in  substantial  fines, 
sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, 
results  of  operations  or  financial  condition.  Further,  resolving  any  additional  investigations  could  be  expensive  and  consume 
significant time and attention of our senior management. For instance, in February 2012, the SEC charged one current and two former 
employees of ours with violating the FCPA in connection with the events that were the subject of the internal investigations we began 
in 2007, as described above. We do not believe that the SEC pleadings against these individuals introduce material facts that were not 
addressed in our internal investigation, which we resolved with the SEC and the DOJ in November 2010. We are not a party to the 
SEC proceedings against these individuals, and we do not believe the charges against the individuals will result in fines, sanctions or 
civil or criminal penalties against us. However, these actions may consume the attention of management and damage our reputation.  

Possible changes in tax laws could affect us and our shareholders.  

We  operate  through  various  subsidiaries  in  numerous  countries  throughout  the  world.  Consequently,  we  are  subject  to 
changes  in  tax  laws,  treaties  or  regulations  or  the  interpretation  or  enforcement  thereof  in  Switzerland,  the  U.S.  or  jurisdictions  in 
which we or any of our subsidiaries operate or are incorporated.  

Tax laws and regulations are highly complex and subject to interpretation. Consequently, we are subject to changing tax 
laws, treaties and regulations in and between countries in which we operate. Our income tax expense is based upon our interpretation 
of the tax laws in effect in various countries at the time that the expense was incurred. If these laws, treaties or regulations change or 
other  taxing  authorities  do  not  agree  with  our  assessment  of  the  effects  of  such  laws,  treaties  and  regulations,  this  could  have  a 
material adverse effect on us, including the imposition of a higher effective tax rate on our worldwide earnings or a reclassification of 
the tax impact of our significant corporate restructuring transactions.  

In addition, the manner in which our shareholders are taxed on distributions on, and dispositions of, our shares could be 
affected by changes in tax laws, treaties or regulations or the interpretation or enforcement thereof in Switzerland, the U.S. or other 
jurisdictions in which our shareholders are resident. Any such changes could result in increased taxes for our shareholders and affect 
the trading price of our shares.  

Our business involves numerous operating hazards.  

Our operations are  subject to many hazards inherent in the drilling business, including blowouts, fires and collisions or 
groundings of offshore equipment, and damage or loss from adverse weather and seas. These hazards could cause personal injury or 
loss  of  life,  suspend  drilling  operations  or  seriously  damage  or  destroy  the  property  and  equipment  involved,  result  in  claims  by 
employees, customers or third parties and, in addition to causing environmental damage, could cause substantial damage to oil  and 
natural gas producing formations or facilities. Operations also may be suspended because of machinery breakdowns, abnormal drilling 
conditions, and failure of subcontractors to perform or supply goods or services, or personnel shortages. Damage to the environment 
could  also  result  from  our  operations,  particularly  through  oil  spillage  or  extensive  uncontrolled  fires.  We  may  also  be  subject  to 
damage claims by oil and gas companies.  

The  contract  drilling  industry  is  a  highly  competitive  and  cyclical  business  with  intense  price  competition.  If  we are 

unable to compete successfully, our profitability may be reduced.  

The  offshore  contract  drilling  industry  is  a  highly  competitive  and  cyclical  business  characterized  by  high  capital  and 
maintenance costs. Drilling contracts are traditionally awarded on a competitive bid basis. Intense price competition, rig availability, 
location  and  suitability,  experience  of  the  workforce,  efficiency,  safety  performance  record,  technical  capability  and  condition  of 
equipment,  operating  integrity,  reputation,  industry  standing  and  client  relations  are  all  factors  in  determining  which  contractor  is 
awarded a job. Mergers among oil and natural gas exploration and production companies from time to time may reduce the number of 
available clients, resulting in increased price competition.  

12 

 
Our industry has historically been cyclical. There have been periods of high demand, short rig supply and high dayrates, 
followed by periods of lower demand, excess rig supply and low dayrates. Periods of excess rig supply intensify the competition in the 
industry and may result in some of our rigs being idle for long periods of time. Prolonged periods of low utilization and low dayrates 
could  result  in  the  recognition  of  impairment  charges  on  certain  of  our  drilling  rigs  if  future  cash  flow  estimates,  based  upon 
information available to management at the time, indicate that the carrying value of these rigs may not be recoverable. For example, in 
2012 our  submersible  rig  fleet,  consisting  of  two  cold  stacked  rigs,  was  partially  impaired  due  to  the  declining  market  outlook  for 
drilling services for this rig type. We estimated the fair value of the rigs based on the salvage value of the rigs and a recent transaction 
involving  a  similar  unit  owned  by  a  peer  company  (Level  2  fair  value  measurement).  Based  on  these  estimates,  we  recognized  a 
charge of approximately $13 million for the year ended December 31, 2012.  

The increase in supply created by the number and types of rigs being built, as well as changes in our competitors’ drilling 
rig fleets, could intensify price competition and require higher capital investment to keep our rigs competitive. In addition, the supply 
attributable  to  newbuild  rigs,  especially  those  being  built  on  speculation,  could  cause  a  reduction  in  future  dayrates.  We  are 
experiencing  competition  from  newbuild  jackups  that  are  scheduled  to  enter  the  market  in  2013  and  beyond.  The  entry  of  these 
newbuild jackups into the market may result in lower dayrates for jackups than currently expected. Similarly, there are a number of 
deepwater newbuilds that are scheduled to enter the market over the next several years, which could also adversely affect the dayrates 
for these units.  

As a result of our significant cash flow needs, we may be required to incur additional indebtedness, or delay or cancel 

discretionary capital expenditures.  

Our currently anticipated cash flow needs, both in the short-term and long-term, may include the following:  

• 

committed capital expenditures, including expenditures for newbuild projects currently underway;  
normal recurring operating expenses;  

• 
•   discretionary capital expenditures, including various capital upgrades;  
•   payments of dividends; and  
repayment of maturing debt.  
• 

In order to fund our capital expenditures, we may need funding beyond the amount available to us from cash generated by 
our operations, cash on hand and borrowings under our existing bank credit facilities and commercial paper program. We may raise 
such additional capital in a number of ways, including accessing capital markets, obtaining additional lines of credit or disposing of 
assets. However, we can provide no assurance that any of these options will be available to us on terms acceptable to us or at all.  

Our ability to obtain financing or to access the capital markets may be limited by our financial condition at the time of any 
such financing and the covenants in our existing debt agreements, as well as by adverse market conditions resulting from, among other 
things, general economic conditions and uncertainties that are beyond our control. Even if we are successful in obtaining additional 
capital through debt financings, incurring additional indebtedness may significantly increase our interest expense and may reduce our 
flexibility  to  respond  to  changing  business  and  economic  conditions  or  to  fund  working  capital  needs,  because  we  will  require 
additional funds to service our outstanding indebtedness.  

We  may  delay  or  cancel  discretionary  capital  expenditures,  which  could  have  certain  adverse  consequences  including 
delaying upgrades or equipment purchases that could make the affected rigs less competitive, adversely affect customer relationships 
and negatively impact our ability to contract such rigs.  

We may have difficulty obtaining or maintaining insurance in the future and our insurance coverage and contractual 

indemnity rights may not protect us against all of the risks and hazards we face.  

We generally identify the operational hazards  for  which  we  will procure insurance coverage based on the likelihood of 
loss,  the  potential  magnitude  of  loss,  the  cost  of  coverage,  the  requirements  of  our  customer  contracts  and  applicable  legal 
requirements. We do not procure insurance coverage for all of the potential risks and hazards we may face. Furthermore, no assurance 
can be given that we will be able to obtain insurance against all of the risks and hazards we face or that we will be able to obtain or 
maintain adequate insurance at rates and with deductibles or retention amounts that we consider commercially reasonable.  

Although  we  maintain  what  we believe to be an appropriate level of insurance covering hazards and risks  we currently 
encounter  during  our  operations,  we  do  not  insure  against  all  possible  hazards  and  risks.  Furthermore,  our  insurance  carriers  may 
interpret our insurance policies such that they do not cover losses for which we make claims. Our insurance policies may also have 
exclusions  of  coverage  for  some  losses.  Uninsured  exposures  may  include  expatriate  activities  prohibited  by  U.S.  laws,  radiation 
hazards, certain loss or damage to property onboard our rigs and losses relating to shore-based terrorist acts or strikes.  

13 

 
In  addition,  the  damage  sustained  to  offshore  oil  and  gas  assets  as  a  result  of  hurricanes  in  recent  years  has  negatively 
impacted  the  energy  insurance  market,  resulting  in  more  restrictive  and  expensive  coverage  for  U.S.  named  windstorm  perils. 
Accordingly, we have elected to significantly reduce the named windstorm insurance on our rigs operating in the U.S. Gulf of Mexico. 
Presently, we insure the Noble Jim Thompson, Noble Amos Runner and Noble Driller for “total loss only” when caused by a named 
windstorm. Our  customer  assumes  the  risk  of  loss  on  the  Noble  Bully  I  due  to  a  named  windstorm  event  up  to  $450  million  per 
occurrence  pursuant  to  the  terms  of  the  drilling  contract  relating  to  such  vessel,  provided  that  we  are  responsible  for  the  first  $25 
million per occurrence for such named windstorm events. The remaining rigs in the U.S. Gulf of Mexico are self-insured for named 
windstorm  perils. Our  rigs  located  in  the  Mexico  portion  of  the  Gulf  of  Mexico  remain  covered  by  commercial  insurance  for 
windstorm damage. If one or more future significant weather-related events occur in the Gulf of Mexico, or in any other geographic 
area in which we operate, we may experience increases in insurance costs, additional coverage restrictions or unavailability of certain 
insurance products.  

Under  our  drilling  contracts,  liability  with  respect  to  personnel  and  property  is  customarily  assigned  on  a  “knock-for-
knock” basis, which means that we and our customers assume liability for our respective personnel and property, irrespective of the 
fault or negligence of the party indemnified. Although our drilling contracts generally provide for indemnification from our customers 
for  certain  liabilities,  including  liabilities  resulting  from  pollution  or  contamination  originating  below  the  surface  of  the  water, 
enforcement of these contractual rights to indemnity may be limited by public policy and other considerations and, in any event, may 
not adequately cover our losses from such incidents. There can also be no assurance that those parties with contractual obligations to 
indemnify us will necessarily be in a financial position to do so.  

Although  we  maintain  insurance  in  the  geographic  areas  in  which  we  operate,  pollution,  reservoir  damage  and 
environmental  risks  generally  are  not  fully  insurable.  Our  insurance  policies  may  not  adequately  cover  our  losses  or  may  have 
exclusions of coverage for some losses. We do not have insurance coverage or rights to indemnity for all risks, including loss of hire 
insurance  on  most  of  the  rigs  in  our  fleet.  Uninsured  exposures  may  include  expatriate  activities  prohibited  by  U.S.  laws  and 
regulations, radiation hazards, certain loss or damage to property onboard our rigs and losses relating to shore-based terrorist acts or 
strikes. If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it could adversely 
affect our financial position, results of operations or cash flows.  

Failure to attract and retain highly skilled personnel or an increase in personnel costs could hurt our operations.  

We require highly  skilled personnel to operate and provide technical  services and support for our drilling  units.  As  the 
demand  for  drilling  services  and  the  size  of  the  worldwide  industry  fleet  increases,  shortages  of  qualified  personnel  have  occurred 
from time to time. These shortages could result in our loss of qualified personnel to competitors, impair our ability to attract and retain 
qualified personnel for our new or existing drilling units, impair the timeliness and quality of our work and create upward pressure on 
personnel costs, any of which could adversely affect our operations.  

Fluctuations in exchange rates and nonconvertibility of currencies could result in losses to us.  

We  may  experience  currency  exchange  losses  where  revenues  are  received  or  expenses  are  paid  in  nonconvertible 
currencies or where we do not hedge an exposure to a foreign currency. We may also incur losses as a result of an inability to collect 
revenues  because  of  a  shortage  of  convertible  currency  available  to  the  country  of  operation,  controls  over  currency  exchange  or 
controls over the repatriation of income or capital.  

We are subject to litigation that could have an adverse effect on us.  

We are, from time to time, involved in various litigation matters. These matters may include, among other things, contract 
disputes,  personal  injury  claims,  asbestos  and  other  toxic  tort  claims,  environmental  claims  or  proceedings,  employment  matters, 
governmental claims for taxes or duties, and other litigation that arises in the ordinary course of our business. Although we intend to 
defend these  matters  vigorously,  we cannot predict  with certainty the outcome or effect of any claim or other litigation  matter, and 
there can be no assurance as to the ultimate outcome of any litigation. Litigation may have an adverse effect on us because of potential 
negative outcomes, costs of attorneys, the allocation of management’s time and attention, and other factors.

Drilling Fleet  

Properties.  

Our  drilling  fleet  is  composed  of  the  following  types  of  units:  semisubmersibles,  drillships,  jackups  and  submersibles. 
Each  type  of  drilling  rig  is  described  further  below.  We  also  own  one  floating  production  storage  and  offloading  unit  (“FPSO”). 
Several factors determine the type of unit most suitable for a particular job, the most significant of which include the water depth and 
the  environment  of  the  intended  drilling  location,  whether  the  drilling  is  being  done  over  a  platform  or  other  structure,  and  the 
intended well depth.  

Semisubmersibles  

Semisubmersibles  are  floating  platforms  which,  by  means  of  a  water  ballasting  system,  can  be  submerged  to  a 
predetermined depth so that a substantial portion of the hull is below the water surface during drilling operations. These units maintain 
their position over the well through the use of either a fixed mooring system or a computer controlled dynamic positioning system and 
can drill in many areas where jackups cannot drill. However, semisubmersibles normally require water depth of at least 200 feet in 
order to conduct operations. Certain of our semisubmersibles are capable of drilling in water depths of up to 12,000 feet.  

The semisubmersible fleet consists of 14 units, including:  
five Noble EVA-4000™ semisubmersibles;  
three Friede & Goldman 9500 Enhanced Pacesetter semisubmersibles;  
two Pentagone 85 semisubmersibles;  
two Bingo 9000 design unit semisubmersibles;  
one Aker H-3 Twin Hull S1289 Column semisubmersible; and  
one Offshore Co. SCP III Mark 2 semisubmersible.

Drillships  

Our drillships are self-propelled vessels. These units maintain their position over the well through the use of either a fixed 
mooring  system  or  a  computer  controlled  dynamic  positioning  system.  Our  drillships  are  capable  of  drilling  in  water  depths  from 
1,000 to 12,000 feet. The maximum drilling depth of our drillships ranges from 20,000 feet to 40,000 feet.  

The drillship fleet consists of 14 units, including:  
four dynamically positioned, ultra-deepwater, harsh environment drillships currently under construction, the first of which 
is estimated to be delivered from the shipyard in the second quarter of 2013;  
three dynamically positioned Gusto Engineering Pelican Class drillships;  
two dynamically positioned Bully-class drillships operated by us through a 50 percent joint venture with a subsidiary of 
Shell;  
one dynamically positioned Globetrotter-class drillship;  
one dynamically positioned Globetrotter-class drillship currently under construction, which is scheduled to be delivered to 
our customer in the fourth quarter of 2013;  
one conventionally moored Sonat Discoverer Class drillship capable of drilling in Arctic environments;  
one dynamically positioned NAM Nedlloyd-C drillship; and  
one conventionally moored conversion class drillship.

Jackups  

We  currently  have  49  jackups  in  our  fleet,  including  six  high-specification,  heavy  duty,  harsh  environment  jackups 
currently under construction. Jackups are mobile, self-elevating drilling platforms equipped with legs that can be lowered to the ocean 
floor until a  foundation is established  for support. The rig  hull includes the drilling rig,  jacking system, crew quarters, loading and 
unloading  facilities,  storage  areas  for  bulk  and  liquid  materials,  helicopter  landing  deck  and  other  related  equipment.  All  of  our 
jackups  are  independent  leg  (i.e.,  the  legs  can  be  raised  or  lowered  independently  of  each  other)  and  cantilevered.  A  cantilevered 
jackup has a feature that permits the drilling platform to be extended out from the hull, allowing it to perform drilling or workover 
operations over pre-existing platforms or structures. Moving a rig to the drill site involves jacking up its legs until the hull is floating 
on the surface of the water. The hull is then towed to the drill site by tugs and the legs are jacked down to the ocean floor. The jacking 
operation continues until the hull is raised out of the water, and drilling operations are conducted with the hull in its raised position. 
Our jackups are capable of drilling to a maximum depth of 30,000 feet in water depths up to 400 feet.  

Submersibles  

We have two submersibles in the fleet which are currently cold-stacked. Submersibles are mobile drilling platforms that 
are towed to the drill site and submerged to drilling position by flooding the lower hull until it rests on the sea floor, with the upper 
deck above the water surface. Our submersibles are capable of drilling to a maximum depth of 25,000 feet in water depths up to 70 
feet.

The declaration and payment of dividends or returns of capital require authorization of the shareholders of Noble-Swiss. 
The amount of such dividends, distributions and returns of capital will depend on our results of operations, financial condition, cash 
requirements, future business prospects, contractual restrictions and other factors deemed relevant by our Board of Directors and our 
shareholders.  

On February 11, 2013, there were 253,225,668 shares outstanding held by 794 shareholder accounts of record.  

Swiss Tax Consequences to Shareholders of Noble-Swiss  

The tax consequences discussed below are not a complete analysis or listing of all the possible tax consequences that may 
be relevant to shareholders of Noble. Shareholders should consult their own tax advisors in respect of the tax consequences related to 
receipt, ownership, purchase or sale or other disposition of our shares and the procedures for claiming a refund of withholding tax.  

Swiss Income Tax on Dividends and Similar Distributions  

A non-Swiss holder will not be subject to Swiss income taxes on dividend income and similar distributions in respect of 
our shares, unless the shares are attributable to a permanent establishment or a fixed place of business maintained in Switzerland by 
such non-Swiss holder. However, dividends and similar distributions are subject to Swiss withholding tax. See “—Swiss Withholding 
Tax–Dividends to Shareholders.”  

Swiss Wealth Tax  

A non-Swiss holder  will not be subject to Swiss  wealth taxes unless the  holder’s shares are attributable to a permanent 

establishment or a fixed place of business maintained in Switzerland by such non-Swiss holder.  

Swiss Capital Gains Tax upon Disposal of Shares  

A non-Swiss holder will not be subject to Swiss income taxes for capital gains unless the holder’s shares are attributable 
to a permanent establishment or a fixed place of business maintained in Switzerland by such non-Swiss holder. In such case, the non-
Swiss holder is required to recognize capital gains or losses on the sale of such shares, which will be subject to cantonal, communal 
and federal income tax.

Swiss Withholding Tax—Dividends to Shareholders  

A  Swiss  withholding  tax  of  35  percent  is  due  on  dividends  to  our  shareholders  from  us,  regardless  of  the  place  of 
residency of the shareholder (subject to the exceptions discussed under “—Exemption from Swiss Withholding Tax–Distributions to 
Shareholders” below). We will be required to withhold at such rate and remit on a net basis any payments made to a holder of our 
shares  and  pay  such  withheld  amounts  to  the  Swiss  federal  tax  authorities.  Please  see  “—Refund  of  Swiss  Withholding  Tax  on 
Dividends and Other Distributions.”  

Exemption from Swiss Withholding Tax—Distributions to Shareholders  

Under present Swiss tax law, distributions to shareholders in relation to a reduction of par value are exempt from Swiss 
withholding tax. Since January 1, 2011, distributions to shareholders out of qualifying additional paid-in capital for Swiss  statutory 
purposes  are  exempt  from  the  Swiss  withholding  tax.  Consequently,  we  expect  that  a  substantial  amount  of  any  potential  future 
distributions,  whether distributed as a reduction of par value or directly out of qualifying additional paid-in capital  may be exempt 
from Swiss withholding tax.  

Repurchases of Shares  

Under present Swiss tax law, repurchases of shares for the purposes of capital reduction are treated as a partial liquidation 
subject to the 35 percent Swiss withholding tax. However, for shares repurchased for capital reduction, the portion of the repurchase 
price attributable to the par value of the shares repurchased will not be subject to the Swiss withholding tax. Since January 1, 2011, the 
portion of the repurchase price attributable to the qualifying additional paid-in capital for Swiss statutory reporting purposes of the 
shares repurchased will also not be subject to the Swiss withholding tax. We would be required to withhold at such rate the tax from 
the difference between the repurchase price and the related amount of par value and the related amount of qualifying additional paid-in 
capital. We would be required to remit on a net basis the purchase price with the Swiss withholding tax deducted to a holder of our 
shares and pay the withholding tax to the Swiss federal tax authorities.  

With respect to the refund of Swiss withholding tax from the repurchase of shares, see “—Refund of Swiss Withholding 

Tax on Dividends and Other Distributions.”  

In  most  instances,  Swiss  companies  listed  on  the  SIX  Swiss  Exchange  (“SIX”),  carry  out  share  repurchase  programs 
through  a  “second  trading  line”  on  the  SIX.  Swiss  institutional  investors  typically  purchase  shares  from  shareholders  on  the  open 
market and then sell the shares on the second trading line back to the company. The Swiss institutional investors are generally able to 
receive  a  full  refund  of  the  withholding  tax.  Due  to,  among  other  things,  the  time  delay  between  the  sale  to  the  company  and  the 
institutional investors’ receipt of the refund, the price companies pay to repurchase their shares has historically been slightly higher 
(but less than 1 percent) than the price of such companies’ shares in ordinary trading on the SIX first trading line.  

We  do  not  expect  to  be  able  to  use  the  SIX  second  trading  line  process  to  repurchase  our  shares  because  we  do  not 
currently intend to list our shares on the SIX. However, we have in the past and intend to continue to follow an alternative process 
whereby we expect to be able to repurchase our shares in a manner that should allow Swiss institutional market participants selling the 
shares to us to receive a refund of the Swiss withholding tax and, therefore, accomplish the same purpose as share repurchases on the 
second trading line at substantially the same cost to us and such market participants as share repurchases on a second trading line.  

The  repurchase  of  shares  for  purposes  other  than  capital  reduction,  such  as  to  retain  as  treasury  shares  for  use  in 
connection  with stock incentive plans, convertible debt or  other instruments  within certain periods,  will generally  not be subject to 
Swiss withholding tax.  

Refund of Swiss Withholding Tax on Dividends and Other Distributions  

Swiss holders – A Swiss tax resident, corporate or individual, can recover the withholding tax in full if such resident is the 
beneficial owner of our shares at the time the dividend or other distribution becomes due and provided that such resident reports the 
gross  distribution  received  on  such  resident’s  income  tax  return,  or  in  the  case  of  an  entity,  includes  the  taxable  income  in  such 
resident’s income statement.  

Non-Swiss holders – If the shareholder that receives a distribution from us is not a Swiss tax resident, does not hold our 
shares in connection with a permanent establishment or a fixed place of business maintained in Switzerland, and resides in a country 
that  has  concluded  a  treaty  for  the  avoidance  of  double  taxation  with  Switzerland  for  which  the  conditions  for  the  application  and 
protection of and by the treaty are met, then the shareholder may be entitled to a full or partial refund of the withholding tax described 
above. The procedures for claiming treaty refunds (and the time  frame required for obtaining a refund)  may differ  from country  to 
country.  

Switzerland  has  entered  into  bilateral  treaties  for  the  avoidance  of  double  taxation  with  respect  to  income  taxes  with 

numerous countries, including the U.S., whereby under certain circumstances all or part of the withholding tax may be refunded.  

20 

 
U.S.  residents  – The  Swiss-U.S.  tax  treaty  provides  that  U.S.  residents  eligible  for  benefits  under  the  treaty  can  seek  a 
refund of the Swiss  withholding tax on dividends  for the portion exceeding 15 percent (leading to a refund of 20 percent) or a full 
refund in the case of qualified pension funds.  

As a general rule, the refund will be granted under the treaty if the U.S. resident can show evidence of:  

beneficial ownership, 
• 
•   U.S. residency, and  
•  meeting the U.S.-Swiss tax treaty’s limitation on benefits requirements. 

The claim for refund must be filed with the Swiss federal tax authorities (Eigerstrasse 65, 3003 Berne, Switzerland), no 
later than December 31 of the third year following the year in which the dividend payments became due. The relevant Swiss tax form 
is Form 82C for companies,  82E for other entities and 82I for individuals. These forms can be obtained from any Swiss Consulate 
General  in  the  U.S.  or  from  the  Swiss  federal  tax  authorities  at  the  address  mentioned  above  or  at  www.estv.admin.ch.  Each  form 
needs  to  be  filled  out  in  triplicate,  with  each  copy  duly  completed  and  signed  before  a  notary  public  in  the  U.S.  Evidence  that  the 
withholding tax was withheld at the source must also be included.  

Stamp duties in relation to the transfer of shares – The purchase or sale of our shares  may be subject to Swiss  federal 
stamp taxes on the transfer of securities irrespective of the place of residency of the purchaser or seller if the transaction takes place 
through or with a Swiss bank or other Swiss securities dealer, as those terms are defined in the Swiss Federal Stamp Tax Act and no 
exemption applies in the specific case. If a purchase or sale is not entered into through or with a Swiss bank or other Swiss securities 
dealer, then no stamp tax will be due. The applicable stamp tax rate is 0.075 percent for each of the two parties to a transaction and is 
calculated based on the purchase price or sale proceeds. If the transaction does not involve cash consideration, the transfer stamp duty 
is computed on the basis of the market value of the consideration.

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

The following discussion is intended to assist you in understanding our financial position at December 31, 2012 and 2011, 
and  our  results  of  operations  for  each  of  the  years  in  the  three-year  period  ended  December 31,  2012.  You  should  read  the 
accompanying consolidated financial statements and related notes in conjunction with this discussion.  

Executive Overview  

Our 2012 financial and operating results include:  

operating revenues totaling $3.5 billion;  

• 
•   net income of $522 million or $2.05 per diluted share;  
• 

•  

net cash from operating activities totaling $1.4 billion; and  
an increase in debt to 35.3 percent of total capitalization at the end of 2012, up from 33.5 percent at the end 
of 2011 due to the issuance of $1.2 billion in senior notes partially offset by a $635 million decrease in the 
amount of debt being drawn on our credit facilities and commercial paper program.

During 2012, we continued to see modest improvement in the offshore drilling market even as the underlying commodity 
markets were subject to short-term volatility. In the U.S. Gulf of Mexico, the granting of permits and publication of new safety rules 
during  the  latter  half  of  2011,  has  led  to  increased  activity  levels  within  the  industry.  The  activity  reflects  the  positive  long-term 
outlook  for  commodity  prices,  which  has  led  to  increased  activity  by  our  customers  and  contributed  to  improved  dayrates  for 
deepwater  and  ultra-deepwater  rigs  worldwide,  and  excellent  geologic  success,  which  is  leading  to  a  backlog  of  appraisal  and 
development projects.  

There continues to be doubt regarding the sustainability of the global economic recovery, which is proceeding unevenly in 
different  geographic  regions.  There  is  also  hesitation  regarding  recovery  in  the  credit  markets,  particularly  in  Europe,  which  some 
analysts predict could be the catalyst for a worldwide recession. Finally, political instability, especially in the Middle East and North 
Africa,  has  further  created  uncertainty  within  the  marketplace. These  factors  may  continue  to  impact  the  price  of  oil  and  gas 
commodities for the foreseeable future, and in turn, could impact the offshore drilling market.  

Despite the instability in the global economy and commodity prices noted above, the market for offshore drilling services 
has continued the upward trend that began during the second half of 2011. We believe both the short-term and long-term outlook for 
the deep and ultra-deepwater  markets continues to strengthen. Market dayrates for  new  ultra-deepwater  units consistently remained 
above $500,000 throughout the year, which is higher than rates seen in recent years. A number of fixtures have exceeded $550,000, 
and in certain cases even exceeded $600,000. Our market analysis indicates that there is little, if any, availability of ultra-deepwater 
units for 2013. In addition, availability of ultra-deepwater units in 2014 continues to decrease. Utilization rates for jackups stabilized 
in 2011, and improved in most regions during 2012. We have seen tangible market activity and anticipate a favorable environment for 
these  rigs  in  the  short-term.  We  continue  to  see  differentiation  in  the  jackup  market,  with  newer  units  having  utilization  rates  and 
dayrates exceeding those for units that entered service before 2000. We continue to see improvement in the older jack-up market with 
increased utilization and competitive dayrates for these rigs as well, with most regions experiencing market utilization of 90 percent or 
higher.  

As part of our strategic planning process, we review our fleet and the strategic benefits of our drilling rigs. As part of this 
process,  we continuously analyze the potential divestment  of certain of our standard specification units and related assets in one or 
more transactions. These dispositions may include sales of assets to third parties, a spin-off or other distribution or separation of assets 
or  a  combination  of  such  transactions.  In  analyzing  our  disposition  alternatives,  we  consider  the  strategic  benefit  to  our  ongoing 
operations while seeking to secure what we consider appropriate value for our shareholders. While we could continue to operate some 
or  all  standard  specification  drilling  rigs,  we  have  taken  certain  preliminary  steps  to  put  ourselves  in  a  better  position  to  pursue  a 
potential  spin-off  and/or  sale  should  we  decide  to  do  so.  These  include  analyzing  the  internal  restructuring  steps  necessary  for  a 
potential  spin-off  or  sale  and  related  tax  considerations,  seeking  certain  preparatory  tax  rulings  and  commencing  preparation  of 
financial  statements  for  a  potential  separate  group  that  could  be  spun  off  or  sold.  We  have  not  completed  the  preliminary  work  to 
effect, nor has our board approved, any such transactions. We make no assurance that we will ultimately undertake any sales or spin-
off or separation transactions involving standard specification assets.  

We have actively expanded our offshore drilling and deepwater capabilities in recent years through the construction and 
acquisition of new rigs. As part of this technical and operational enhancement, we plan to continue pursuing opportunities to upgrade 
our fleet to achieve greater technological capability, which should increase our operational efficiencies.  

During 2012, we continued our newbuild program as indicated by the following activities:  

•  we commenced operations on three dynamically positioned ultra-deepwater, harsh environment drillships: two Bully-class 
drillships  currently  operating  in  the  U.S.  Gulf  of  Mexico  and  Brazil,  respectively,  and  one  Globetrotter-class  drillship 
currently operating in the U.S. Gulf of Mexico;  

•  we  continued  construction  on  one  dynamically  positioned,  ultra-deepwater,  harsh  environment  Globetrotter-class 

drillship, which is scheduled to be delivered to our customer in the fourth quarter of 2013;  

•  we  continued  construction  on  four  dynamically  positioned,  ultra-deepwater,  harsh  environment  drillships  at  Hyundai 
Heavy Industries Co. Ltd., the first of which is estimated to be delivered from the shipyard in the second quarter of 2013; 
and  

•  we  continued  construction  on  six  high-specification,  heavy  duty,  harsh  environment  jackups,  the  first  of  which  is 

estimated to be delivered from the shipyard in the second quarter of 2013.  

While  we  cannot  predict  the  future  level  of  demand  or  dayrates  for  our  drilling  services  or  future  conditions  in  the 
offshore  contract  drilling  industry,  we  continue  to  believe  we  are  well  positioned  within  the  industry  and  believe  our  continued 
newbuild activity will further strengthen our position, especially in deepwater drilling.  

24 

 
We have entered into an agreement to sell our jackup, the  Noble Lewis Dugger, to a third party that owns and operates 
supply  vessels,  platform  drilling  rigs  and  jackups  in  Mexico. This  unit  is  being  sold  for  $61  million  and  the  closing  is  expected  to 
occur in the second quarter of 2013 after the unit has completed its contract with its current customer. The transaction is subject to 
customary closing conditions. We had entered into an agreement to sell the Noble Don Walker for $18 million. The buyer was unable 
to close the transaction, although we remain in discussions to potentially extend the sale agreement. The unit has been cold-stacked in 
Cameroon since 2009.  

Contract Drilling Services Backlog  

We maintain a backlog (as defined below) of commitments for contract drilling services. The following table sets forth as 
of December 31, 2012 the amount of our contract drilling services backlog and the percent of available operating days committed for 
the periods indicated:

(In millions) 

(1)  Our drilling contracts with Petrobras provide an opportunity for us to earn performance bonuses based on downtime experienced 
for our rigs operating offshore Brazil. With respect to our semisubmersibles operating offshore Brazil for Petrobras, we  have 
included  in  our  backlog  an  amount  equal  to  75  percent  of  potential  performance  bonuses  for  such  semisubmersibles.  With 
respect to our drillships presently operating offshore Brazil for Petrobras, we have included in our backlog an amount equal to 
75  percent  of  potential  performance  bonuses  for  periods  after  the  estimated  completion  of  certain  upgrade  projects  that  are 
designed to enhance the reliability and operational performance of the drillships. Our  backlog for semisubmersibles/drillships 
includes approximately $197 million attributable to these performance bonuses.  

      The  drilling  contracts  with  Shell  for  the  Noble  Globetrotter  I,  Noble  Globetrotter  II,  Noble  Jim  Thompson,  Noble  Clyde 
Boudreaux,  Noble  Max  Smith,  Noble  Don  Taylor  and  the  Noble  Jim  Day,  provide  opportunities  for  us  to  earn  performance 
bonuses based on key performance indicators as defined by Royal Dutch Shell, PLC (“Shell”). With respect to these contracts, 
we have included in our backlog an amount equal to 50 percent of the potential performance bonuses for these rigs. Our backlog 
for these rigs includes approximately $409 million attributable to these performance bonuses.  

(2)  Pemex  has  the  ability  to  cancel  its  drilling  contracts  on  30  days  or  less  notice  without  Pemex’s  making  an  early  termination 
payment. At December 31, 2012, we had 12 rigs contracted to Pemex in Mexico, and our backlog includes approximately $613 
million related to such contracts.  

(3)  Our drilling contracts generally provide the customer an early termination right in the event we fail to meet certain performance 
standards,  including  downtime  thresholds.  For  example,  Petrobras  has  the  right  to  terminate  its  contracts  in  the  event  of 
excessive  downtime.  While  we  have  exceeded  downtime  thresholds  in  the  past  on  certain  rigs  contracted  with  Petrobras,  we 
have not received any notification concerning contract cancellations nor do we anticipate receiving any such notifications.  
(4)  Percentages  take  into  account  additional  capacity  from  the  estimated  dates  of  deployment  of  our  newbuild  rigs  that  are 

scheduled to commence operations during 2013 through 2015.  

(5)  Noble and a subsidiary of Shell are involved in joint ventures that own and operate both the Noble Bully I and the Noble Bully 
II.  Under  the  terms  of  the  joint  venture  agreements,  each  party  has  an  equal  50  percent  share  in  both  vessels.  As  of 
December 31, 2012, the combined amount of backlog for these rigs totals $2.28 billion, all of which is included in our backlog. 
Noble’s proportional interest in the backlog for these rigs was $1.14 billion.  

Our contract drilling services backlog reported above reflects estimated future revenues attributable to both signed drilling 
contracts and letters of intent that we expect to realize. A letter of intent is generally subject to customary conditions, including the 
execution of a definitive drilling contract. It is possible that some customers that have entered into letters of intent will not enter into 
signed drilling contracts. We calculate backlog for any given unit and period by multiplying the full contractual operating dayrate for 
such unit by  the  number of days remaining in the period. The reported contract drilling services backlog does not include amounts 
representing  revenues  for  mobilization,  demobilization  and  contract  preparation,  which  are  not  expected  to  be  significant  to  our 
contract drilling services revenues, amounts constituting reimbursables from customers or amounts attributable to uncommitted option 
periods under drilling contracts or letters of intent.

The  amount  of  actual  revenues  earned  and  the  actual  periods  during  which  revenues  are  earned  may  be  materially 
different than the backlog amounts and backlog periods set forth in the table above due to various factors, including, but not limited to, 
shipyard and maintenance projects, unplanned downtime, achievement of bonuses, weather conditions and other factors that result in 
applicable  dayrates  lower  than  the  full  contractual  operating  dayrate.  In  addition,  amounts  included  in  the  backlog  may  change 
because drilling contracts may be varied or modified by mutual consent or customers may exercise early termination rights contained 
in some of our drilling contracts or decline to enter into a drilling contract after executing a letter of intent. As a result, our backlog as 
of any particular date may not be indicative of our actual operating results for the periods for which the backlog is calculated.  

Nigerian Operations  

As previously disclosed, in November 2010 we finalized settlements with the SEC and the DOJ as the result of an internal 
investigation of the legality under the United States Foreign Corrupt Practices Act (“FCPA”) and local laws of certain reimbursement 
payments made by our Nigerian affiliate to our customs agents in Nigeria. In January 2011, a subsidiary of Noble-Swiss resolved an 
investigation by the Nigerian Economic and Financial Crimes Commission and the Nigerian Attorney General Office into these same 
activities.  Any  additional  investigation  by  these  or  other  agencies  could  damage  our  reputation  and  result  in  substantial  fines, 
sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, 
results  of  operations  or  financial  condition.  Further,  resolving  any  additional  investigations  could  be  expensive  and  consume 
significant time and attention of our senior management.  

Acquisition of Frontier Holdings Limited  

On  July 28,  2010,  Noble-Swiss  and  Noble  AM  Merger  Co.,  a  Cayman  Islands  company  and  indirect  wholly-owned 
subsidiary  of  Noble-Swiss  (“Merger  Sub”),  completed  the  acquisition  of  FDR  Holdings  Limited,  a  Cayman  Islands  company 
(“Frontier”). Under the terms of the Agreement and Plan of Merger with Frontier and certain of Frontier’s shareholders, Merger Sub 
merged with and into Frontier, with Frontier surviving as an indirect wholly-owned subsidiary of Noble-Swiss and a wholly-owned 
subsidiary of Noble-Cayman. The Frontier acquisition was for a purchase price of approximately $1.7 billion in cash plus liabilities 
assumed  and  strategically  expanded  and  enhanced  our  global  fleet.  Frontier’s  results  of  operations  were  included  in  our  results 
beginning July 28, 2010. We funded the cash consideration paid at closing of approximately $1.7 billion using proceeds from our July 
2010 offering of senior notes and existing cash on hand.  

RESULTS OF OPERATIONS  
2012 Compared to 2011  
General  

The consolidated financial statements of Noble-Swiss include the accounts of Noble-Cayman, and Noble-Swiss conducts 
substantially all of its business through Noble-Cayman and its subsidiaries. As a result, the financial position and results of operations 
for Noble-Cayman, and the reasons for material changes in the amount of revenue and expense items between 2012 and 2011, would 
be the same as the information presented below regarding Noble-Swiss in all material respects, except operating income for Noble-
Cayman for the year ended December 31, 2012 was $58 million higher than operating income for Noble-Swiss for the same period, 
primarily as a result of costs directly attributable to Noble-Swiss for operations support and stewardship related services.  

Net  income  attributable  to  Noble  Corporation  for  2012  was  $522  million,  or  $2.05  per  diluted  share,  on  operating 
revenues of $3.5 billion, compared to net income for 2011 of $371 million, or $1.46 per diluted share, on operating revenues of $2.7 
billion.

**  Not a meaningful percentage.  

Operating  Revenues.  Changes  in  contract  drilling  services  revenues  for  the  current  year  as  compared  to  the  prior  year 
were driven by increases in both average dayrates and operating days. The 17 percent increase in average dayrates increased revenues 
by approximately $479 million while the 12 percent increase in operating days increased revenues by an additional $314 million.  

The  increase  in  contract  drilling  services  revenues  relates  to  our  semisubmersibles,  drillships  and  jackups,  which 

generated approximately $293 million, $255 million and $245 million more revenue, respectively, in 2012.  

The  18  percent  increase  in  semisubmersible  average  dayrates  resulted  in  a  $232  million  increase  in  revenues  from  the 
prior year while the increase in operating days of 5 percent resulted in an additional $61 million increase in revenues. The increase in 
semisubmersibles revenue is a result of our rigs returning to standard operating dayrates after experiencing lower standby rates due to 
drilling  restrictions  in  the  U.S.  Gulf  of  Mexico  in  the  prior  year,  as  well  as  the  Noble  Paul  Romano  returning  to  work  after  being

stacked for most of the prior year. The increase in operating days is primarily from the Noble Jim Day, the Noble Homer Ferrington, 
the  Noble Paul Romano, the  Noble Clyde Boudreaux and the Noble Amos Runner,  which all operated during  the current  year after 
being off contract for the majority of the prior year.  

The  increase  in  drillship  revenues  was  driven  by  a  58  percent  increase  in  operating  days  and  a  15  percent  increase  in 
average dayrates, resulting in a $179 million and a $76 million increase in revenues, respectively, from the prior year. The increase in 
both  average  dayrates  and  operating  days  was  the  result  of  the  Noble  Bully  I,  Noble  Bully  II  and  Noble  Globetrotter  I,  which 
commenced their contracts with Shell in March 2012, April 2012 and July 2012, respectively. These increases were partially offset by 
the Noble Phoenix, which completed its shipyard project and was substituted for the Noble Muravlenko in Brazil during the current 
year, and a reduced rate on the Noble Roger Eason while it is in the shipyard to undergo its reliability upgrade project.  

The 13 percent increase in jackup average dayrates resulted in a $145 million increase in revenues, which was coupled 
with a 10 percent increase in jackup operating days, resulting in a $100 million increase in revenues from the prior year. The increase 
in  average  dayrates  resulted  from  improved  market  conditions  in  the  global  shallow  water  market  throughout  the  jackup  fleet.  The 
increase in utilization primarily related to rigs in Mexico, West Africa and the Middle East, which experienced less downtime during 
the current year.  

Operating  Costs  and  Expenses.  Contract  drilling  services  operating  costs  and  expenses  increased  $392  million  for  the 
current  year as compared to the prior year.  A portion of the increase is due to the crew-up and operating expenses  for the recently 
completed rigs noted above, which have added approximately $139 million in expense in the current year. Excluding the additional 
expenses related to these rigs, our contract drilling costs increased $253 million in the current year from the prior year. This change 
was  primarily  driven  by  a  $75  million  increase  in  labor  due  to  rigs  returning,  or  preparing  to  return,  to  work  and  salary  increases 
effective in the second and third quarters of the prior year, a $47 million increase in shorebase support due to salary increases in the 
current year and increased project-related costs, a $44 million increase in maintenance and rig-related expense, a $26 million increase 
in mobilization due to the amortization of certain rig moves and the demobilization of rigs primarily in Mexico, a $20 million increase 
in  insurance  costs  related  to  increased  premiums  on  our  policy  renewed  in  March  2012,  a  $14  million  increase  in  rig  catering  and 
communications,  a  $13  million  increase  in  safety,  training  and  regulatory  inspections,  a  $6  million  increase  in  agency  and  other 
miscellaneous expenses, a $5 million increase in fuel and transportation costs and a $3 million increase in rotation costs.  

Depreciation and amortization increased $98 million in 2012 over 2011, which is primarily attributable to assets placed in 

service during the current year, including the Noble Bully I, Noble Bully II and the Noble Globetrotter I.  

Loss on impairment during the current year related to an impairment charge on our submersible fleet, primarily as a result 

of the declining market outlook for drilling services for this rig type.  

Gain on contract settlements/extinguishments during the current year related to a $28 million gain on the settlement of an 
action with certain vendors for damages sustained during Hurricane Ike. Additionally, we received $5 million from a claims settlement 
on the Noble David Tinsley, which had experienced a “punch-through” while being positioned on location in 2009.

Operating Revenues and Costs and Expenses. The increase in both revenue and expense primarily relates  to a project 

with our customer, Shell, for one of its rigs operating under a labor contract in Alaska.  

Loss on impairment during the current year related to an impairment charge on certain corporate assets, as a result of a 

declining market for, and the potential disposal of, the assets.  

Other Income and Expenses  

Selling, general and administrative expenses. Overall selling, general and administrative expenses increased $9 million 
in 2012 from 2011 primarily as a result of increased legal and tax expenses related to ongoing projects of $5 million, coupled with 
increases in employee-related costs of $4 million.  

Interest Expense, net of amount capitalized. Interest expense, net of amount capitalized, increased $30 million in 2012 
from 2011. The increase is a result of the $1.2 billion of senior notes issued in February 2012, coupled with lower capitalized interest 
due  primarily  to  the  completion  of  construction  on  three  of  our  newbuild  drillships.  During  the  current  year,  we  capitalized 
approximately 61 percent of total interest charges versus approximately 69 percent during the prior year.  

Income Tax Provision. Our income tax provision increased $74 million in 2012 compared to 2011 primarily as a result of 
a higher pre-tax earnings and effective tax rate during the current year. Pre-tax earnings increased approximately 61 percent in 2012 
compared to 2011 resulting in a $45 million increase in income tax expense. The higher effective tax rate, which was 20.9 percent in 
2012 compared to 16.7 percent in 2011, increased income tax expense by approximately $29 million. The increase in the effective tax 
rate was a result of a change in our geographic mix of our revenues and the resolution of certain discrete tax items.  

2011 Compared to 2010  
General  

The consolidated financial statements of Noble-Swiss include the accounts of Noble-Cayman, and Noble-Swiss conducts 
substantially all of its business through Noble-Cayman and its subsidiaries. As a result, the financial position and results of operations 
for Noble-Cayman, and the reasons for material changes in the amount of revenue and expense items between 2011 and 2010, would 
be the same as the information presented below regarding Noble-Swiss in all material respects, except operating income for Noble-
Cayman for the year ended December 31, 2011 was $49 million higher than operating income for Noble-Swiss for the same period, 
primarily as a result of costs directly attributable to Noble-Swiss for operations support and stewardship related services.

Net  income  attributable  to  Noble  Corporation  for  2011  was  $371  million,  or  $1.46  per  diluted  share,  on  operating 
revenues of $2.7 billion, compared to net income for 2010 of $773 million, or $3.02 per diluted share, on operating revenues of $2.8 
billion.  

Rig Utilization, Operating Days and Average Dayrates

Operating Revenues. Decreased contract drilling services revenues for the current year as compared to the prior year was 
driven by reductions in both  average dayrates and operating days. The 3 percent decrease in average dayrates reduced revenues by 
approximately $71 million, and the 3 percent decrease in operating days decreased revenues by an additional $68 million.  

The decrease in contract drilling services revenues primarily relates to our jackups, drillships and FPSO, which generated 

approximately $191 million, $46 million and $34 million less revenue, respectively, in 2011.  

The decrease in jackup average dayrates of 12 percent resulted in a $135 million decrease in revenues from the prior year. 
The reduction in average dayrates was primarily from the contractual repricing of rigs in the Middle East, the North Sea, and Mexico 
for changes in market conditions in the global shallow water market. The 5 percent decline in jackup operating days resulted in a $56

million decline in revenues. The decrease in utilization primarily related to rigs coming off contract in Mexico and the Middle East 
during 2011, the majority of which did not return to work until the latter part of the year.  

The  decrease  in  drillship  revenue  was  primarily  driven  by  reduced  dayrates  of  5  percent  and  an  8  percent  decrease  in 
operating days, which resulted in decreased revenues of $18 million and $28 million, respectively, from the prior year. The decrease in 
drillship revenue is primarily the result of increased downtime in Brazil, as rigs entered the shipyard for upgrades and repairs.  

Revenue from the Noble Seillean decreased $34 million as it was not under contract in 2011.  

The decreases in revenue for the above rig classes were partially offset by an increase in revenue of $132 million from our 
semisubmersibles. The increase was primarily attributable to a 9 percent increase in operating days and 3 percent increase in average 
dayrates,  which  contributed  additional  revenue  in  2011  of  $98  million  and  $34  million,  respectively.  The  increase  is  primarily 
attributable to operations from the newbuilds, Noble Dave Beard and Noble Jim Day, which were added to the fleet in March 2010 
and January 2011, respectively. Additionally, the Noble Driller was added to the fleet in July 2010 as part of the Frontier acquisition.  

Operating  Costs  and  Expenses.  Contract  drilling  services  operating  costs  and  expenses  increased  $206  million  for  the 
current year as compared to the prior year. The rigs added to the fleet as part of the Frontier acquisition and the Noble Dave Beard and 
the Noble Jim Day added approximately $120 million of operating costs in the current year. Excluding the additional expenses related 
to  these  rigs,  our  contract  drilling  costs  increased  $86  million  in  the  current  year  from  the  prior  year.  This  increase  was  primarily 
driven  by  a  $22  million  increase  in  maintenance  and  rig-related  expenses,  $20  million  increase  in  mobilization  costs,  $18  million 
increase  in  labor  costs,  and  an  $11  million  increase  in  safety  and  training  costs.  These  cost  increases  were  primarily  for  our  rigs 
returning, or preparing to return, to work in Brazil and Mexico. Additionally, rotation costs and operations support costs increased $10 
million and $5 million, respectively.  

Depreciation and amortization increased $119 million in 2011 over 2010 as a result of depreciation on newbuilds placed 
into service, rigs added to the fleet as part of the Frontier acquisition and additional depreciation related to other capital expenditures 
on our fleet since the beginning of 2010.

Operating  Revenues  and  Costs  and  Expenses.  The  increase  in  both  revenue  and  expense  primarily  relates  to  the 
commencement of a refurbishment project with our customer, Shell, for one of its rigs to be operated under a labor contract in Alaska, 
combined with operational increases and foreign currency fluctuations in our Canadian operations.  

Other Income and Expenses  

Selling, general and administrative expenses. Overall selling, general and administrative expenses were consistent with 
2010  as  a  $6  million  increase  primarily  related  to  ongoing  legal  and  tax  expenses  in  the  current  year  was  offset  by  a  $6  million 
decrease resulting from the absence of costs related to our completed FCPA investigation in the prior year.

Interest Expense, net of amount capitalized. Interest expense, net of amount capitalized, increased $46 million in 2011 
from  2010.  The  increase  is  a  result  of  $1.25  billion  of  debt  issued  in  July  2010,  which  was  used  to  partially  fund  the  Frontier 
acquisition, $1.1 billion of debt issued in February 2011, which was primarily used to repay the outstanding balance on our revolving 
credit facility and to repay our portion of outstanding debt under the joint venture credit facilities, and current year drawdowns on the 
credit facilities.  

Income  Tax  Provision.  Our  income  tax  provision  decreased  $70  million  in  2011  compared  to  2010  primarily  due  to  a 
reduction in pre-tax earnings, which was partially offset by a higher effective tax rate. Pre-tax earnings decreased approximately 52 
percent in 2011 compared to 2010 resulting in a reduction of approximately $75 million in income tax expense. The higher effective 
tax  rate,  which  was  16.7  percent  in  2011  compared  to  15.6  percent  in  2010,  increased  income  tax  expense  by  approximately  $5 
million. The increase in the effective tax rate was a result of a change in our geographic revenue mix primarily resulting from drilling 
restrictions in the U.S. Gulf of Mexico, partially offset by the resolution of discrete tax items.  

LIQUIDITY AND CAPITAL RESOURCES  

Overview  

Net cash from operating activities in 2012 was $1.4 billion, which compared to $740 million and $1.6 billion in 2011 and 
2010,  respectively.  The  increase  in  net  cash  from  operating  activities  in  2012  compared  to  2011  was  primarily  attributable  to  a 
significant increase in net income coupled with favorable changes in deferred taxes and other current liabilities, partially offset by an 
increase  in  accounts  receivable.  We  had  working  capital  of  $394  million  and  $232  million  at  December 31,  2012  and  2011, 
respectively. Our total debt as a percentage of total debt plus equity increased to 35.3 percent at December 31, 2012 from 33.5 percent 
at  December 31,  2011,  primarily  as  a  result  of  our  $1.2  billion  senior  notes  offering  in  February  2012,  partially  offset  by  a  net 
reduction in indebtedness outstanding on our credit facilities and commercial paper program during the year.  

Our principal sources of capital in 2012 were the $1.4 billion in cash generated from operating activities noted above and 
our $1.2 billion senior notes offering in February 2012. Cash generated during the current year was primarily used to fund our capital 
expenditure program and to repay borrowings outstanding under our credit facilities and commercial paper program.  

Our currently anticipated cash flow needs, both in the short-term and long-term, include the following:  

committed capital expenditures, including expenditures for newbuild projects currently underway;  

•  
•   normal recurring operating expenses;  
• 
•   payments of dividends; and  
repayment of maturing debt.  
• 

discretionary capital expenditures, including various capital upgrades;  

We currently expect to fund these cash flow needs with cash generated by our operations, cash on hand, borrowings under 
our existing credit facilities and commercial paper program and issuances of unsecured long-term debt. However, to adequately cover 
our expected cash flow needs, we may require capital in excess of the amount provided through these sources, and we may delay or 
cancel certain discretionary capital expenditures as necessary.  

At December 31, 2012, we had a total contract drilling services backlog of approximately $14.3 billion. Our backlog as of 
December 31,  2012  reflects  a  commitment  of  74  percent  of  available  days  for  2013.  See  “Contract  Drilling  Services  Backlog”  for 
additional information regarding our backlog.  

Capital Expenditures  

Our  primary  use  of  available  liquidity  during  2013  will  be  for  capital  expenditures.  Capital  expenditures,  including 
capitalized interest, totaled $1.7 billion, $2.6 billion and $1.4 billion for 2012, 2011 and 2010, respectively. Capital expenditures for 
2010 do not include the fair value of assets acquired as part of the Frontier acquisition.  

32 

 
At  December 31,  2012,  we  had  11  rigs  under  construction,  and  capital  expenditures,  excluding  capitalized  interest,  for 

new construction during 2012 totaled $587 million, as follows (in millions):

In addition to the newbuild expenditures noted above, capital expenditures during 2012 consisted of the following:  

• 

$693 million for major projects, including subsea-related expenditures;  

•   $254 million for other capitalized expenditures, including upgrades and replacements to drilling equipment 

that generally have a useful life ranging from 3 to 5 years; and  

•   $136 million in capitalized interest.  

Our total capital expenditures budget for 2013 is approximately $2.7 billion, which is currently anticipated to be spent as 

follows:  

•  

• 

•  

approximately $1.5 billion in newbuild expenditures;  
approximately $870 million in major projects, including subsea-related expenditures; and  
approximately $320 million in sustaining capitalized expenditures.  

In addition to the amounts noted above, we anticipate incurring additional capitalized interest, which may fluctuate as a 
result  of  the  timing  of  completion  of  ongoing  projects.  In  connection  with  our  capital  expenditure  program,  we  have  entered  into 
certain commitments, including shipyard and purchase commitments, for approximately $2.8 billion at December 31, 2012, of which 
we expect to spend approximately $1.7 billion in 2013.  

From time to time we consider possible projects that would require capital expenditures or other cash expenditures that are 
not included in our capital budget, and such unbudgeted capital or cash expenditures could be significant. In addition, we will continue 
to  evaluate  acquisitions  of  drilling  units  from  time  to  time.  Other  factors  that  could  cause  actual  capital  expenditures  to  materially 
exceed  planned  capital  expenditures  include  delays  and  cost  overruns  in  shipyards  (including  costs  attributable  to  labor  shortages), 
shortages  of  equipment,  latent  damage  or  deterioration  to  hull,  equipment  and  machinery  in  excess  of  engineering  estimates  and 
assumptions, changes in governmental regulations and requirements and changes in design criteria or specifications during repair or 
construction.  

Distributions of Capital and Dividends  

Our  most  recent  quarterly  dividend  payment  to  shareholders,  which  was  declared  on  February 1,  2013  and  paid  on 
February 21, 2013 to holders of record on February 11, 2013, was $0.13 per share, or an aggregate of approximately $33 million. The 
declaration  and  payment  of  dividends,  or  returns  of  capital  in  the  form  of  par  value  reductions,  require  authorization  of  the 
shareholders  of  Noble-Swiss.  The  amount  of  such  dividends,  distributions  and  returns  of  capital  will  depend  on  our  results  of

operations, financial condition, cash requirements, future business prospects, contractual restrictions and other factors deemed relevant 
by our Board of Directors and shareholders.  

Recently,  our  Board  of  Directors  approved  as  a  proposal  to  shareholders  at  our  upcoming  annual  general  meeting 
scheduled for April 26, 2013 the payment of a dividend funded from our capital contribution reserve in a total amount equal to $1.00 
per share to be paid in four equal installments scheduled for August 2013, November 2013, February 2014 and May 2014.  

Credit Facilities and Senior Unsecured Notes  
Credit Facilities and Commercial Paper Program  

Noble currently has a maximum available capacity of $800 million on our credit facility maturing in 2015 and $1.5 billion 
on our credit facility maturing in 2017 (together referred to as the “Credit Facilities”). Our total debt related to the Credit Facilities and 
commercial paper program was $340 million at December 31, 2012 as compared to $975 million at December 31, 2011. During 2012, 
we  undertook  a  series  of  transactions  that  increased  our  liquidity.  We  see  this  as  a  necessary  step  to  finance  our  future  capital 
commitments. The following summarizes the recent activity regarding our Credit Facilities and commercial paper program:  

•  

• 

•  

in  June  2012,  we  replaced  our  $575  million  credit  facility  scheduled  to  mature  in  2013,  with  a  new  $1.2 
billion credit facility, which matures in 2017;  
in  September  2012,  we  established  a  commercial  paper  program,  which  will  allow  us  to  issue  up  to  $1.8 
billion  in  unsecured  commercial  paper  notes. Amounts  issued  under  the  commercial  paper  program  are 
supported by the unused committed capacity under our Credit Facilities and, as such, are classified as long-
term on our Consolidated Balance Sheet; and  
in January 2013, we increased the maximum amount available under our Credit Facilities from $1.8 billion 
to  $2.3  billion.  The  maximum  amount  available  under  our  credit  facility  maturing  in  2015  was  increased 
from $600 million to $800 million and the maximum amount available under our credit facility maturing in 
2017 was increased from $1.2 billion to $1.5 billion.  

The  Credit  Facilities  provide  us  with  the  ability  to  issue  up  to  $375  million  in  letters  of  credit  in  the  aggregate.  The 
issuance of letters of credit does not increase our borrowings outstanding under the Credit Facilities, but it does reduce the amount 
available. At December 31, 2012, we had no letters of credit issued under the Credit Facilities.  

Senior Unsecured Notes  

Our  total  debt  related  to  senior  unsecured  notes  was  $4.3  billion  at  December 31,  2012  as  compared  to  $3.1  billion  at 
December 31,  2011.  The  increase  in  debt  is  a  result  of  the  issuance  of  $1.2  billion  aggregate  principal  amount  of  senior  notes  in 
February 2012, which we issued through our indirect wholly-owned subsidiary, Noble Holding International Limited (“NHIL”). These 
senior notes were issued in three separate tranches, with $300 million of 2.50% Senior Notes due 2017, $400 million of 3.95% Senior 
Notes due 2022, and $500 million of 5.25% Senior Notes due 2042. The weighted average coupon of all three tranches is 4.13%. The 
net proceeds of approximately $1.19 billion, after expenses, were primarily used to repay the then outstanding balance on our Credit 
Facilities.  

Our  5.875%  Senior  Notes  mature  during  the  second  quarter  of  2013.  We  anticipate  using  availability  under  our  Credit 
Facilities or commercial paper program to repay the outstanding balance; therefore, we continue to report the balance as long-term at 
December 31, 2012.  

Covenants  

The Credit Facilities and commercial paper program are guaranteed by our indirect wholly-owned subsidiaries, NHIL and 
Noble  Drilling  Corporation  (“NDC”).  The  covenants  and  events  of  default  under  the  Credit  Facilities  are  substantially  similar,  and 
each facility contains a covenant that limits our ratio of debt to total tangible capitalization, as defined in the Credit Facilities, to 0.60. 
At December 31, 2012, our ratio of debt to total tangible capitalization was less than 0.36. We were in compliance with all covenants 
under the Credit Facilities as of December 31, 2012.  

In  addition  to  the  covenants  from  the  Credit  Facilities  noted  above,  the  indentures  governing  our  outstanding  senior 
unsecured notes contain covenants that place restrictions on certain merger and consolidation transactions, unless we are the surviving 
entity or the other party assumes the obligations under the indenture, and on the ability to sell or transfer all or substantially all of our 
assets. In addition, there are restrictions on incurring or assuming certain liens and sale and lease-back transactions. At December 31, 
2012, we were in compliance with all our debt covenants. We continually monitor compliance with the covenants under our notes and, 
based on our expectations for 2013, expect to remain in compliance during the year.  

34 

 
Other  

At December 31, 2012, we had letters of credit of $48 million and performance and tax assessment bonds totaling $264 
million  supported  by  surety  bonds  outstanding.  Additionally,  certain  of  our  subsidiaries  issue  guarantees  to  the  temporary  import 
status  of  rigs  or  equipment  imported  into  certain  countries  in  which  we  operate. These  guarantees  are  issued  in-lieu  of  payment  of 
custom, value added or similar taxes in those countries.

(1) 

In 2013, our 5.875% senior notes and amounts outstanding under our commercial paper program mature. We anticipate using 
availability on our Credit Facilities or commercial paper program to repay these outstanding balances; therefore, we have shown 
the  entire  $300  million  senior  notes  balance  and  $340  million  commercial  paper  program  balance  as  long-term  on  our 
December 31, 2012 Consolidated Balance Sheet.  

(2)  Purchase commitments consist of obligations outstanding to external vendors primarily related to future capital purchases.  
(3)  Tax  reserves  are  included  in  “Other”  due  to  the  difficulty  in  making  reasonably  reliable  estimates  of  the  timing  of  cash 

settlements to taxing authorities. See Note 12 to our accompanying consolidated financial statements.  

At  December 31,  2012,  we  had  other  commitments  that  we  are  contractually  obligated  to  fulfill  with  cash  if  the 
obligations are called. These obligations include letters of credit and surety bonds that guarantee our performance as it relates to our 
drilling  contracts,  tax  and  other  obligations  in  various  jurisdictions.  These  letters  of  credit  and  surety  bond  obligations  are  not 
normally called, as we typically comply with the underlying performance requirement.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES  

Our  consolidated  financial  statements  are  impacted  by  the  accounting  policies  used  and  the  estimates  and  assumptions 
made  by  management  during  their  preparation.  Critical  accounting  policies  and  estimates  that  most  significantly  impact  our 
consolidated financial statements are described below.  

Principles of Consolidation  

The consolidated financial statements include our accounts, those of our wholly-owned subsidiaries and entities in which 
we hold a controlling financial interest. Our consolidated financial statements include the accounts of two joint ventures, in each of 
which  we  own  a  50  percent  interest.  Our  ownership  interest  meets  the  definition  of  variable  interest  under  Financial  Accounting 
Standards  Board  (“FASB”)  codification  and  we  have  determined  that  we  are  the  primary  beneficiary.  Intercompany  balances  and 
transactions have been eliminated in consolidation.

The combined joint venture carrying amount of the Bully-class drillships at December 31, 2012 totaled $1.4 billion, which 
was primarily funded through partner equity contributions. During 2012, these rigs commenced the operating phases of their contracts. 
Current year revenues and net income related to these joint ventures totaled $237 million and $71 million, respectively.  

Property and Equipment  

Property  and  equipment  is  stated  at  cost,  reduced  by  provisions  to  recognize  economic  impairment  in  value  whenever 
events or changes in circumstances indicate an asset’s carrying value may not be recoverable. At December 31, 2012 and 2011, we 
had  $2.7  billion  and  $4.4  billion  of  construction-in-progress,  respectively.  Such  amounts  are  included  in  “Drilling  equipment  and 
facilities” in the accompanying Consolidated Balance Sheets. Major replacements and improvements are capitalized. When assets are 
sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or 
loss is recognized. Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as 
of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three to thirty 
years. Other property and equipment is depreciated using the straight-line method over useful lives ranging from two to twenty-five 
years.  

Interest is capitalized on construction-in-progress at the interest rate on debt incurred for construction or at the weighted 
average cost of debt outstanding during the period of construction. Capitalized interest for the years ended December 31, 2012, 2011 
and 2010 was $136 million, $122 million and $83 million, respectively.  

Scheduled  maintenance  of  equipment  is  performed  based  on  the  number  of  hours  operated  in  accordance  with  our 
preventative maintenance program. Routine repair and maintenance costs are charged to expense as incurred; however, the costs of the 
overhauls and asset replacement projects that benefit future periods and which typically occur every three to five years are capitalized 
when incurred and depreciated over an equivalent period. These overhauls and asset replacement projects are included in  “Drilling 
equipment and  facilities” in the Consolidated Balance Sheets. Such amounts,  net of accumulated depreciation, totaled $303 million 
and  $233  million  at  December 31,  2012  and  2011,  respectively.  Depreciation  expense  related  to  overhauls  and  asset  replacement 
totaled $113 million, $103 million and $102 million for the years ended December 31, 2012, 2011 and 2010, respectively.  

We  evaluate  the  realization  of  property  and  equipment  whenever  events  or  changes  in  circumstances  indicate  that  the 
carrying amount of an asset may not be recoverable. In addition, on an annual basis, we complete an impairment analysis on all of our 
assets. An impairment loss on our property and equipment exists when the estimated undiscounted cash flows expected to result from 
the  use  of  the  asset  and  its  eventual  disposition  are  less  than  its  carrying  amount. Any  impairment  loss  recognized  represents  the 
excess  of  the  asset’s  carrying  value  over  the  estimated  fair  value. As  part  of  this  analysis,  we  make  assumptions  and  estimates 
regarding future market conditions. To the extent actual results do not meet or exceed our estimated assumptions, for a given rig class, 
we may take an impairment loss in the future.  

During the current  year  we determined that our submersible rig  fleet, consisting of  two  cold stacked rigs,  was partially 
impaired due to the declining market outlook for drilling services for this rig type. We estimated the fair value of the rigs based on the 
salvage value of the rigs and a recent transaction involving a similar unit owned by a peer company (Level 2 fair value measurement). 
Based on these estimates, we recognized a charge of approximately $13 million for the year ended December 31, 2012. Also, during 
the current year, we determined that certain corporate assets were partially impaired due to a declining market for, and the potential 
disposal of, the assets. We estimated the fair value of the asset based on a signed letter of intent to sell the asset (Level 2 fair value 
measurement). Based on these estimates, we recognized a charge of approximately $7 million for the year ended December 31, 2012.  

Insurance Reserves  

We  maintain  various  levels  of  self-insured  retention  for  certain  losses  including  property  damage,  loss  of  hire, 
employment practices liability, employers’ liability, and general liability, among others. We accrue for property damage and loss of 
hire charges on a per event basis.  

Employment practices liability claims are accrued based on actual claims during the year. Maritime employer’s liability 
claims are generally estimated using actuarial determinations. General liability claims are estimated by our internal claims department 
by evaluating the facts and circumstances of each claim (including incurred but not reported claims) and making estimates based upon 
historical  experience  with  similar  claims.  At  December 31,  2012  and  2011,  loss  reserves  for  personal  injury  and  protection  claims 
totaled $20 million and $21 million, respectively, and such amounts are included in “Other current liabilities” in the accompanying 
Consolidated Balance Sheets.  

36 

 
Revenue Recognition  

Revenues generated from our dayrate-basis drilling contracts and labor contracts are recognized as services are performed. 

Revenues from bonuses are recognized when earned.  

We  may  receive  lump-sum  fees  for  the  mobilization  of  equipment  and  personnel.  Mobilization  fees  received  and  costs 
incurred to mobilize a drilling unit from one market to another are recognized over the term of the related drilling contract. Absent a 
contract,  the  initial  mobilization  costs  of  newbuild  rigs  from  the  shipyard  are  deferred  and  amortized  over  the  life  of  the  rig. 
Subsequent costs incurred to relocate drilling units to more promising geographic areas in which a contract has not been secured are 
expensed as incurred. Lump-sum payments received from customers relating to specific contracts, including equipment modifications, 
are  deferred  and  amortized  to  income  over  the  term  of  the  drilling  contract.  Upon  completion  of  our  drilling  contracts,  any 
demobilization revenues received are recognized as income, as are any related expenses.  

Deferred  revenues  under  drilling  contracts  totaled  $252  million  and  $139  million  at  December 31,  2012  and  2011, 
respectively.  Such  amounts  are  included  in  either  “Other  Current  Liabilities”  or  “Other  Liabilities”  in  our  Consolidated  Balance 
Sheets, based upon our expected time of recognition.  

We  record  reimbursements  from  customers  for  “out-of-pocket”  expenses  as  revenues  and  the  related  direct  cost  as 

operating expenses.  

Income Taxes  

We operate through various subsidiaries in numerous countries throughout the world including the United States. Income 
taxes have been provided based on the laws and rates in effect in the countries in which operations are conducted or in which we or 
our subsidiaries are considered resident for income tax purposes. The income and  withholding tax rates and  methods  of computing 
taxable income vary significantly for each jurisdiction. Consequently, we are subject to changes in tax laws, treaties or regulations or 
the interpretation or enforcement thereof in the U.S., Switzerland or jurisdictions in which we or any of our subsidiaries operate or are 
resident. Our income  tax expense is based upon our interpretation of the tax  laws in effect in  various countries at the time that the 
expense was incurred. If the U.S. Internal Revenue Service (“IRS”) or other taxing authorities do not agree with our assessment of the 
effects  of  such  laws,  treaties  and  regulations,  this  could  have  a  material  adverse  effect  on  us,  including  the  imposition  of  a  higher 
effective  tax  rate  on  our  worldwide  earnings  or  a  reclassification  of  the  tax  impact  of  our  significant  corporate  restructuring 
transactions. Our income tax expense is expected to fluctuate from year to year as our operations and income fluctuates in the different 
taxing jurisdictions.  

We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to 
review and examination by tax authorities within those jurisdictions. The IRS has completed its examination of our tax reporting for 
the taxable year ended December 31, 2008. The examination team has proposed adjustments with respect to certain items that were 
reported by us for the 2008 tax year. We believe that we have accurately reported all amounts included in our 2008 tax returns, and 
have filed protests with the IRS Appeals Office contesting the examination team’s proposed adjustments, and we are still waiting on a 
final resolution of these issues. We intend to vigorously defend our reported positions. The IRS has begun its examination of our tax 
reporting  for  the  taxable  year  ended  December 31,  2009. We  believe  that  we  have  accurately  reported  all  amounts  in  our  2009  tax 
returns.  During  the  third  quarter  of  2012,  a  U.S.  subsidiary  of  Frontier  concluded  its  audit  with  the  IRS  for  its  2007  and  2008  tax 
returns, resulting in no change to income tax expense. Furthermore, we are currently contesting several non-U.S. tax assessments and 
may contest future assessments when we disagree with those assessments based on the technical merits of the positions established at 
the time of the filing of the tax return. We believe the ultimate resolution of the outstanding assessments, for which we have not made 
any accrual, will not have a material adverse effect on our consolidated financial statements. We recognize uncertain tax positions that 
we  believe  have  a  greater  than  50 percent  likelihood  of  being  sustained.  We  cannot  predict  or  provide  assurance  as  to  the  ultimate 
outcome of the existing or future assessments.  

Our  Mexican  income  tax  returns  have  been  examined  for  the  2002  through  2007  periods  and  audit  claims  have  been 
assessed for approximately $321 million (including interest and penalties). During 2011, we received from the Regional Chamber of 
the Federal Tax Court adverse decisions with respect to approximately $6 million in assessments related to depreciation deductions, 
which  we are appealing. We  are also contesting all other assessments in Mexico. Tax authorities in Mexico and other jurisdictions 
may issue additional assessments or pursue legal actions as a result of tax audits and we cannot predict or provide assurance as to the 
ultimate outcome of such assessments and legal actions.  

Additional audit claims of approximately $123 million attributable to income, customs and other business taxes have been 
assessed against us in other jurisdictions. We have contested, or intend to contest, these assessments, including through litigation if 
necessary, and we believe the ultimate resolution, for which we have not made any accrual, will not have a material adverse effect on 
our consolidated financial statements.  

37 

 
Applicable income and withholding taxes have not been provided on undistributed earnings of our subsidiaries. We do not 
intend to repatriate such undistributed earnings except for distributions upon which incremental income and withholding taxes would 
not be material.  

In certain jurisdictions we have recognized deferred tax assets and liabilities. Judgment and assumptions are required in 
determining  whether  deferred  tax  assets  will  be  fully  or  partially  utilized.  When  we  estimate  that  all  or  some  portion  of  certain 
deferred tax assets  such as net operating loss carryforwards  will  not be utilized,  we establish a  valuation allowance  for the  amount 
ascertained to be unrealizable. We continually evaluate strategies that could allow  for future  utilization of our deferred assets.  Any 
change in the ability to utilize such deferred assets will be accounted for in the period of the event affecting the valuation allowance. If 
facts and circumstances cause us to change our expectations regarding future tax consequences, the resulting adjustments could have a 
material effect on our financial results or cash flow.  

In  certain  circumstances,  we  expect  that,  due  to  changing  demands  of  the  offshore  drilling  markets  and  the  ability  to 
redeploy our offshore drilling units, certain units will not reside in a location long enough to give rise to future tax consequences. As a 
result,  no  deferred  tax  asset  or  liability  has  been  recognized  in  these  circumstances.  Should  our  expectations  change  regarding  the 
length of time an offshore drilling unit will be used in a given location, we will adjust deferred taxes accordingly.  

Certain Significant Estimates and Contingent Liabilities  

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of  America  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and 
disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses 
during the reporting period. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable 
likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been 
used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other 
assumptions  that  are  believed  to  be  reasonable  under  the  circumstances,  the  results  of  which  form  the  basis  for  making  judgments 
about carrying  values of assets and liabilities that are not readily apparent from other sources.  Actual results  may differ from these 
estimates  and  assumptions  used  in  preparation  of  our  consolidated  financial  statements.  In  addition,  we  are  involved  in  several 
litigation  matters,  some  of  which  could  lead  to  potential  liability  to  us.  We  follow  FASB  standards  regarding  contingent  liabilities 
which are discussed in “Part II Item 8. Financial Statements and Supplementary Data, Note 16- Commitments and Contingencies” of 
our annual report on form 10-K.  

New Accounting Pronouncements  

In  May  2011,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Accounting  Standards  Update  (“ASU”) 
No. 2011-04,  which  amends  FASB  Accounting  Standards  Codification  (“ASC”)  Topic  820,  “Fair  Value  Measurements  and 
Disclosures.”  This  amended  guidance  clarifies  the  wording  used  to  describe  many  of  the  requirements  in  accounting  literature  for 
measuring  fair  value  and  for  disclosing  information  about  fair  value  measurements.  The  goal  of  the  amendment  is  to  create 
consistency  between  the  United  States  and  international  accounting  standards.  The  guidance  is  effective  for  annual  and  interim 
reporting  periods  beginning  on  or  after  December 15,  2011.  Our  adoption  of  this  guidance  did  not  have  a  material  impact  on  our 
financial condition, results of operations, cash flows or financial disclosures.  

In June 2011, the FASB issued ASU No. 2011-05, which amends ASC Topic 220, “Comprehensive Income.” This ASU 
allows  an  entity  to  present  the  total  of  comprehensive  income,  the  components  of  net  income,  and  the  components  of  other 
comprehensive  income  either  in  a  single  continuous  statement  of  comprehensive  income  or  in  two  separate  but  consecutive 
statements. The amendment no longer allows an entity to show changes to other comprehensive income solely through the statement 
of  equity.  For  publicly  traded  entities,  the  guidance  is  effective  for  annual  and  interim  reporting  periods  beginning  on  or  after 
December 15, 2011. In December 2011, the FASB issued ASU No. 2011-12, which defers only those changes in ASU 2011-05 that 
relate to the presentation of reclassification adjustments. Our adoption of this guidance did not have a material impact on our financial 
condition, results of operations, cash flows or financial disclosures.

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk.  

Market risk is the potential  for loss due to a change in the value of a financial  instrument as a result of  fluctuations in 

interest rates, currency exchange rates or equity prices, as further described below.  

Interest Rate Risk  

We are subject to market risk exposure related to changes in interest rates on borrowings under the Credit Facilities and 
commercial  paper  program.  Interest  on  borrowings  under  the  Credit  Facilities  is  at  an  agreed  upon  percentage  point  spread  over 
LIBOR,  or  a  base  rate  stated  in  the  agreement.  At  December 31,  2012,  we  had  $340  million  in  borrowings  outstanding  under  our 
commercial paper program, which is supported by the Credit Facilities. Assuming our current level of debt, a change in LIBOR rates 
of 1 percent would increase our interest charges by approximately $3 million per year.  

We maintain certain debt instruments at a fixed rate whose fair value will fluctuate based on changes in interest rates and 
market perceptions of our credit risk. The fair value of our total debt was $5.1 billion and $4.3 billion at December 31, 2012 and 2011, 
respectively. The increase was primarily a result of our issuance of $1.2 billion in debt in February 2012, partially offset by the net 
repayment of $635 million on our Credit Facilities coupled with changes in fair value related to changes in interest rates and market 
perceptions of our credit risk.  

Foreign Currency Risk  

Although we are a Swiss corporation, we define foreign currency as any non-U.S. denominated currency. Our functional 
currency is primarily the U.S. Dollar, which is consistent with the oil and gas industry. However, outside the United States, some of 
our expenses are incurred in local currencies. Therefore, when the U.S. Dollar weakens (strengthens) in relation to the currencies of 
the countries in which we operate, our expenses reported in U.S. Dollars will increase (decrease).  

We are exposed to risks on future cash flows to the extent that local currency expenses exceed revenues denominated in 
local  currency  that  are  other  than  the  functional  currency.  To  help  manage  this  potential  risk,  we  periodically  enter  into  derivative 
instruments  to  manage  our  exposure  to  fluctuations  in  currency  exchange  rates,  and  we  may  conduct  hedging  activities  in  future 
periods  to  mitigate  such  exposure.  These  contracts  are  primarily  accounted  for  as  cash  flow  hedges,  with  the  effective  portion  of 
changes in the  fair value of the hedge recorded on the Consolidated Balance Sheet and in “Accumulated other comprehensive loss” 
(“AOCL”). Amounts recorded in AOCL are reclassified into earnings in the same period or periods that the hedged item is recognized 
in  earnings.  The  ineffective  portion  of  changes  in  the  fair  value  of  the  hedged  item  is  recorded  directly  to  earnings.  We  have 
documented  policies  and  procedures  to  monitor  and  control  the  use  of  derivative  instruments.  We  do  not  engage  in  derivative 
transactions for speculative or trading purposes, nor are we a party to leveraged derivatives.  

Our  North  Sea  and  Brazil  operations  have  a  significant  amount  of  their  cash  operating  expenses  payable  in  local 
currencies. To limit the potential risk of currency fluctuations, we have historically maintained short-term forward contracts settling 
monthly  in  their  respective  local  currencies.  At  December 31,  2012,  we  had  no  outstanding  derivative  contracts.  At  December 31, 
2011,  total  unrealized  loss  related  to  forward  contracts  was  $3  million,  which  was  recorded  as  part  of  AOCL  in  our  Consolidated 
Balance Sheet. Depending on market conditions, we may elect to utilize short-term forward currency contracts in the future.  

 Market Risk  

We sponsor the Noble Drilling Corporation 401(k) Savings Restoration Plan (“Restoration Plan”). The Restoration Plan is 
a nonqualified, unfunded employee benefit plan under which certain highly compensated employees may elect to defer compensation 
in  excess  of  amounts  deferrable  under  our  401(k)  savings  plan.  The  Restoration  Plan  has  no  assets,  and  amounts  withheld  for  the 
Restoration Plan are kept by us for general corporate purposes. The investments selected by employees and the associated returns are 
tracked on a phantom basis. Accordingly, we have a liability to employees for amounts originally withheld plus phantom investment 
income or less phantom investment losses. We are at risk for phantom investment income and, conversely, benefit should phantom 
investment  losses  occur.  At  December 31,  2012,  our  liability  under  the  Restoration  Plan  totaled  $7  million.  We  have  purchased 
investments  that  closely  correlate  to  the  investment  elections  made  by  participants  in  the  Restoration  Plan  in  order  to  mitigate  the 
impact of the phantom investment income and losses on our consolidated financial statements. The value of these investments held for 
our benefit totaled $6 million at December 31, 2012. A 10 percent change in the fair value of the phantom investments would change 
our liability by approximately $0.6 million. Any change in the fair value of the phantom investments would be mitigated by a change 
in the investments held for our benefit.  

We  also  have  a  U.S.  noncontributory  defined  benefit  pension  plan  that  covers  certain  salaried  employees  and  a  U.S. 
noncontributory  defined  benefit  pension  plan  that  covers  certain  hourly  employees,  whose  initial  date  of  employment  is  prior  to 
August 1, 2004 (collectively referred to as our “qualified U.S. plans”). These plans are governed by the Noble Drilling Corporation 
Retirement  Trust  (the  “Trust”).  The  benefits  from  these  plans  are  based  primarily  on  years  of  service  and,  for  the  salaried  plan, 

39 

 
employees’ compensation near retirement. These plans are designed to qualify under the Employee Retirement Income Security Act of 
1974 (“ERISA”), and our funding policy is consistent with funding requirements of ERISA and other applicable laws and regulations. 
We make cash contributions, or utilize credits available to us, for the qualified U.S. plans when required. The benefit amount that can 
be  covered  by  the  qualified  U.S.  plans  is  limited  under  ERISA  and  the  Internal  Revenue  Code  (“IRC”)  of  1986.  Therefore,  we 
maintain  an  unfunded,  nonqualified  excess  benefit  plan  designed  to  maintain  benefits  for  all  employees  at  the  formula  level  in  the 
qualified salary U.S. plan. We refer to the qualified U.S. plans and the excess benefit plan collectively as the “U.S. plans”.  

In  addition  to  the  U.S.  plans,  each  of  Noble  Drilling  (Land  Support)  Limited,  Noble  Enterprises  Limited  and  Noble 
Drilling  (Nederland)  B.V.,  all  indirect,  wholly-owned  subsidiaries  of  Noble-Swiss,  maintains  a  pension  plan  that  covers  all  of  its 
salaried,  non-union  employees  (collectively  referred  to  as  our  “non-U.S.  plans”).  Benefits  are  based  on  credited  service  and 
employees’ compensation near retirement, as defined by the plans.  

Changes  in  market  asset  value  related  to  the  pension  plans  noted  above  could  have  a  material  impact  upon  our 

Consolidated Statements of Comprehensive Income and could result in material cash expenditures in future periods.

Report of Independent Registered Public Accounting Firm  

To the Board of Directors and  
Shareholders of Noble Corporation, a Swiss Corporation (“Noble-Swiss”)  

In  our  opinion,  the  accompanying  consolidated  balance  sheets  and  the  related  consolidated  statements  of  income,  comprehensive 
income,  equity  and  cash  flows  present  fairly,  in  all  material  respects,  the  financial  position  of  Noble-Swiss  and  its  subsidiaries  at 
December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2012 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, 
the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on 
criteria  established  in  Internal  Control  -  Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway  Commission  (COSO).  Noble-Swiss’  management  is  responsible  for  these  financial  statements,  for  maintaining  effective 
internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included 
in  Management’s  Annual  Report  on  Internal  Control  over  Financial  Reporting  appearing  under  Item  9A.  Our  responsibility  is  to 
express opinions on these financial statements and on Noble-Swiss’ internal control over financial reporting based on our integrated 
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 audits to obtain reasonable assurance about whether the financial statements are 
free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. 
Our  audits  of  the  financial  statements  included  examining,  on  a  test  basis,  evidence  supporting  the  amounts  and  disclosures  in  the 
financial  statements,  assessing  the  accounting  principles  used  and  significant  estimates  made  by  management,  and  evaluating  the 
overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of 
internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and 
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.  

A company’s internal control over financial reporting is a process designed 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  (i) pertain  to  the 
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company; (ii) 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  (iii) 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm  

To the Board of Directors and  
Shareholder of Noble Corporation, a Cayman Islands Company (“Noble-Cayman”)  

In  our  opinion,  the  accompanying  consolidated  balance  sheets  and  the  related  consolidated  statements  of  income,  comprehensive 
income, equity and cash flows present fairly, in all material respects, the financial position of Noble-Cayman and its subsidiaries at 
December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2012 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, 
the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on 
criteria  established  in  Internal  Control  -  Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway Commission (COSO). Noble-Cayman’ management is responsible for these financial statements, for maintaining effective 
internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included 
in  Management’s  Annual  Report  on  Internal  Control  over  Financial  Reporting  appearing  under  Item  9A.  Our  responsibility  is  to 
express opinions on these financial statements and on Noble-Cayman’ internal control over financial reporting based on our integrated 
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 audits to obtain reasonable assurance about whether the financial statements are 
free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. 
Our  audits  of  the  financial  statements  included  examining,  on  a  test  basis,  evidence  supporting  the  amounts  and  disclosures  in  the 
financial  statements,  assessing  the  accounting  principles  used  and  significant  estimates  made  by  management,  and  evaluating  the 
overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of 
internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and 
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.  

A company’s internal control over financial reporting is a process designed 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  (i) pertain  to  the 
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company; (ii) 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  (iii) 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOBLE CORPORATION (NOBLE-SWISS) AND SUBSIDIARIES 
NOBLE CORPORATION (NOBLE-CAYMAN) AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

Note 1 – Organization and Significant Accounting Policies  
Organization and Business  

Noble  Corporation,  a  Swiss  corporation  (“Noble-Swiss”),  is  a  leading  offshore  drilling  contractor  for  the  oil  and  gas 
industry. We perform contract drilling services with our fleet of 79 mobile offshore drilling units located worldwide. We also own one 
floating  production  storage  and  offloading  unit.  Our  fleet  consists  of  14  semisubmersibles,  14  drillships,  49  jackups  and  two 
submersibles, including 11 units under construction as follows:  

• 

• 

five dynamically positioned, ultra-deepwater, harsh environment drillships and  
six high-specification, heavy-duty, harsh environment jackups.  

As of February 7, 2013, approximately 85 percent of our fleet was located outside the United States in the following areas: 
Mexico, Brazil, the North Sea, the Mediterranean, West Africa, the Middle East, India and Australia. Noble and its predecessors have 
been engaged in the contract drilling of oil and gas wells since 1921.  

Noble Corporation, a Cayman Islands company (“Noble-Cayman”) is a direct, wholly-owned subsidiary of Noble-Swiss, 
our publicly-traded parent company. Noble-Swiss’ principal asset is all of the shares of Noble-Cayman. Noble-Cayman has no public 
equity outstanding. The consolidated financial  statements  of Noble-Swiss include the accounts of  Noble-Cayman, and Noble-Swiss 
conducts substantially all of its business through Noble-Cayman and its subsidiaries.  

Principles of Consolidation  

The consolidated financial statements include our accounts, those of our wholly-owned subsidiaries and entities in which 
we hold a controlling financial interest. Our consolidated financial statements include the accounts of two joint ventures, in each of 
which  we  own  a  50  percent  interest.  Our  ownership  interest  meets  the  definition  of  variable  interest  under  Financial  Accounting 
Standards  Board  (“FASB”)  codification  and  we  have  determined  that  we  are  the  primary  beneficiary.  Intercompany  balances  and 
transactions have been eliminated in consolidation.  

Foreign Currency Translation  

Although  we  are  a  Swiss  corporation,  we  define  foreign  currency  as  any  non-U.S.  denominated  currency.  In  non-U.S. 
locations  where  the  U.S. Dollar  has  been  designated  as  the  functional  currency  (based  on  an  evaluation  of  factors  including  the 
markets  in  which  the  subsidiary  operates,  inflation,  generation  of  cash  flow,  financing  activities  and  intercompany  arrangements), 
local currency transaction gains and losses are included in net income. In non-U.S. locations where the local currency is the functional 
currency,  assets  and  liabilities  are  translated  at  the  rates  of  exchange  on  the  balance  sheet  date,  while  income  statement  items  are 
translated at average rates of exchange during the year. The resulting gains or losses arising from the translation of accounts from the 
functional currency to the U.S. Dollar are included in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. 
We  did  not  recognize  any  material  gains  or  losses  on  foreign  currency  transactions  or  translations  during  the  three  years  ended 
December 31, 2012.  

Cash and Cash Equivalents  

Cash  and  cash  equivalents  include  cash  on  hand,  demand  deposits  with  banks  and  all  highly  liquid  investments  with 
original maturities of three months or less. Our cash, cash equivalents and short-term investments are subject to potential credit risk, 
and certain of our cash accounts carry balances greater than the federally insured limits. Cash and cash equivalents are primarily held 
by major banks or investment firms. Our cash management and investment policies restrict investments to lower risk, highly liquid 
securities  and  we  perform  periodic  evaluations  of  the  relative  credit  standing  of  the  financial  institutions  with  which  we  conduct 
business.  

Cash flows from our labor contract drilling services in Canada are calculated based on the Canadian Dollar. As a result, 
amounts  related  to  assets  and  liabilities  reported  on  the  Consolidated  Statements  of  Cash  Flows  will  not  necessarily  agree  with 
changes in the corresponding balances on the Consolidated Balance Sheets. The effect of exchange rate changes on cash balances held 
in foreign currencies was not material for all periods presented.  

Property and Equipment  

Property  and  equipment  is  stated  at  cost,  reduced  by  provisions  to  recognize  economic  impairment  in  value  whenever 
events or changes in circumstances indicate an asset’s carrying value may not be recoverable. At December 31, 2012 and 2011, there

NOBLE CORPORATION (NOBLE-SWISS) AND SUBSIDIARIES 
NOBLE CORPORATION (NOBLE-CAYMAN) AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

was  $2.7  billion  and  $4.4  billion  of  construction-in-progress,  respectively.  Such  amounts  are  included  in  “Drilling  equipment  and 
facilities” in the accompanying Consolidated Balance Sheets. Major replacements and improvements are capitalized. When assets are 
sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or 
loss is recognized. Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as 
of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three to thirty 
years. Other property and equipment is depreciated using the straight-line method over useful lives ranging from two to twenty-five 
years.  Included  in  accounts  payable  was  $141  million  and  $256  million  of  capital  accruals  as  of  December 31,  2012  and  2011, 
respectively.  

Interest is capitalized on construction-in-progress at the interest rate on debt incurred for construction or at the weighted 
average cost of debt outstanding during the period of construction. Capitalized interest for the years ended December 31, 2012, 2011 
and 2010 was $136 million, $122 million and $83 million, respectively.  

Scheduled  maintenance  of  equipment  is  performed  based  on  the  number  of  hours  operated  in  accordance  with  our 
preventative maintenance program. Routine repair and maintenance costs are charged to expense as incurred; however, the costs of the 
overhauls and asset replacement projects that benefit future periods and which typically occur every three to five years are capitalized 
when incurred and depreciated over an equivalent period. These overhauls and asset replacement projects are included in  “Drilling 
equipment and  facilities” in the Consolidated Balance Sheets. Such amounts,  net of accumulated depreciation, totaled $303 million 
and  $233  million  at  December 31,  2012  and  2011,  respectively.  Depreciation  expense  related  to  overhauls  and  asset  replacement 
totaled $113 million, $103 million and $102 million for the years ended December 31, 2012, 2011 and 2010, respectively.  

We  evaluate  the  realization  of  property  and  equipment  whenever  events  or  changes  in  circumstances  indicate  that  the 
carrying amount of an asset may not be recoverable. In addition, on an annual basis, we complete an impairment analysis on all of our 
assets. An impairment loss on our property and equipment exists when the estimated undiscounted cash flows expected to result from 
the  use  of  the  asset  and  its  eventual  disposition  are  less  than  its  carrying  amount. Any  impairment  loss  recognized  represents  the 
excess  of  the  asset’s  carrying  value  over  the  estimated  fair  value. As  part  of  this  analysis,  we  make  assumptions  and  estimates 
regarding future market conditions. To the extent actual results do not meet or exceed our estimated assumptions, for a given rig class, 
we may take an impairment loss in the future.  

During the current  year  we determined that our submersible rig  fleet, consisting of  two  cold stacked rigs,  was partially 
impaired due to the declining market outlook for drilling services for this rig type. We estimated the fair value of the rigs based on the 
salvage value of the rigs and a recent transaction involving a similar unit owned by a peer company (Level 2 fair value measurement). 
Based on these estimates, we recognized a charge of approximately $13 million for the year ended December 31, 2012. Also, during 
the current year, we determined that certain corporate assets were partially impaired due to a declining market for, and the potential 
disposal of, the assets. We estimated the fair value of the assets based on a signed letter of intent to sell the assets (Level 2 fair value 
measurement). Based on these estimates, we recognized a charge of approximately $7 million for the year ended December 31, 2012.  

Deferred Costs  

Deferred debt issuance costs are being amortized through interest expense over the life of the debt securities.  

Insurance Reserves  

We  maintain  various  levels  of  self-insured  retention  for  certain  losses  including  property  damage,  loss  of  hire, 
employment practices liability, employers’ liability, and general liability, among others. We accrue for property damage and loss of 
hire charges on a per event basis.  

Employment practices liability claims are accrued based on actual claims during the year. Maritime employer’s liability 
claims are generally estimated using actuarial determinations. General liability claims are estimated by our internal claims department 
by evaluating the facts and circumstances of each claim (including incurred but not reported claims) and making estimates based upon 
historical  experience  with  similar  claims.  At  December 31,  2012  and  2011,  loss  reserves  for  personal  injury  and  protection  claims 
totaled $20 million and $21 million, respectively, and such amounts are included in “Other current liabilities” in the accompanying 
Consolidated Balance Sheets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

Revenue Recognition  

Revenues generated from our dayrate-basis drilling contracts and labor contracts are recognized as services are performed. 

Revenues from bonuses are recognized when earned.  

We  may  receive  lump-sum  fees  for  the  mobilization  of  equipment  and  personnel.  Mobilization  fees  received  and  costs 
incurred to mobilize a drilling unit from one market to another are recognized over the term of the related drilling contract. Absent a 
contract,  the  initial  mobilization  costs  of  newbuild  rigs  from  the  shipyard  are  deferred  and  amortized  over  the  life  of  the  rig. 
Subsequent costs incurred to relocate drilling units to more promising geographic areas in which a contract has not been secured are 
expensed as incurred. Lump-sum payments received from customers relating to specific contracts, including equipment modifications, 
are  deferred  and  amortized  to  income  over  the  term  of  the  drilling  contract.  Upon  completion  of  our  drilling  contracts,  any 
demobilization revenues received are recognized as income, as are any related expenses.  

Deferred  revenues  under  drilling  contracts  totaled  $252  million  at  December 31,  2012  as  compared  to  $139  million  at 
December 31,  2011.  Such  amounts  are  included  in  either  “Other  Current  Liabilities”  or  “Other  Liabilities”  in  our  Consolidated 
Balance Sheets, based upon our expected time of recognition.  

We  record  reimbursements  from  customers  for  “out-of-pocket”  expenses  as  revenues  and  the  related  direct  cost  as 

operating expenses.  

Income Taxes  

Income taxes are based on the laws and rates in effect in the countries in which operations are conducted or in which we 
or our subsidiaries are considered resident for income tax purposes. Applicable income and withholding taxes have not been provided 
on undistributed earnings of our subsidiaries. We do not intend to repatriate such undistributed earnings except for distributions upon 
which  incremental  income  and  withholding  taxes  would  not  be  material.  In  certain  circumstances,  we  expect  that,  due  to  changing 
demands of the offshore drilling markets and the ability to redeploy our offshore drilling units, certain of such units will not reside in a 
location long enough to give rise to future tax consequences. As a result, no deferred tax asset or liability has been recognized in these 
circumstances. Should our expectations change regarding the length of time an offshore drilling unit will be used in a given location, 
we will adjust deferred taxes accordingly.  

We  operate  through  various  subsidiaries  in  numerous  countries  throughout  the  world  including  the  United  States. 
Consequently, we are subject to changes in tax laws, treaties or regulations or the interpretation or enforcement thereof in the U.S., 
Switzerland or jurisdictions in which we or any of our subsidiaries operate or are resident. Our income tax expense is based upon our 
interpretation  of  the  tax  laws  in  effect  in  various  countries  at  the  time  that  the  expense  was  incurred.  If  the  U.S.  Internal  Revenue 
Service (“IRS”) or other taxing authorities do not agree with our assessment of the effects of such laws, treaties and regulations, this 
could  have  a  material  adverse  effect  on  us  including  the  imposition  of  a  higher  effective  tax  rate  on  our  worldwide  earnings  or  a 
reclassification of the tax impact of our significant corporate restructuring transactions.  

Net Income per Share  

Our unvested share-based payment awards, which contain non-forfeitable rights to dividends, are participating securities 
and  are  included  in  the  computation  of  earnings  per  share  pursuant  to  the  “two-class”  method.  The  “two-class”  method  allocates 
undistributed earnings between common shares and participating securities. The diluted earnings per share calculation under the “two-
class” method also includes the dilutive effect of potential shares issued in connection with stock options. The dilutive effect of stock 
options is determined using the treasury stock method.  

Share-Based Compensation Plans  

We record the grant date fair value of share-based compensation arrangements as compensation cost using a straight-line 
method over the service period. Share-based compensation is expensed or capitalized based on the nature of the employee’s activities.  

Certain Significant Estimates  

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of  America  (“GAAP”)  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and 
liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues 
and expenses during the reporting period. Certain accounting policies involve judgments and uncertainties to such an extent that there 
is  reasonable  likelihood  that  materially  different  amounts  could  have  been  reported  under  different  conditions,  or  if  different 
assumptions  had  been  used.  We  evaluate  our  estimates  and  assumptions  on  a  regular  basis.  We  base  our  estimates  on  historical 

56 

NOBLE CORPORATION (NOBLE-SWISS) AND SUBSIDIARIES 
NOBLE CORPORATION (NOBLE-CAYMAN) AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

experience and various other assumptions that are believed to be reasonable under the circumstances, the results of  which form the 
basis  for  making  judgments  about  carrying  values  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources.  Actual 
results may differ from these estimates and assumptions used in preparation of our consolidated financial statements.  

Reclassifications  

Certain amounts in prior periods have been reclassified to conform to the current year presentation. In connection with a 
review of the “Other Assets” caption in our financial statements, we determined that drilling equipment replacements and upgrades 
should be included in “Property and equipment”. As a result, we reclassified these amounts in our Consolidated Balance Sheet for the 
year  ended  December 31,  2011. We  believe  these  reclassifications  are  immaterial  as  they  do  not  have  a  material  impact  on  our 
financial position, results of operations or cash flows.  

Accounting Pronouncements  

In May 2011, the  FASB issued Accounting  Standards Update (“ASU”) No. 2011-04, which amends FASB  Accounting 
Standards  Codification  (“ASC”)  Topic  820,  “Fair  Value  Measurements  and  Disclosures.”  This  amended  guidance  clarifies  the 
wording used to describe many of the requirements in accounting literature for  measuring  fair value and for disclosing information 
about  fair  value  measurements.  The  goal  of  the  amendment  is  to  create  consistency  between  the  United  States  and  international 
accounting standards. The guidance is effective  for annual and interim reporting periods beginning on or after December 15, 2011. 
Our adoption of this guidance did not have a material impact on our financial condition, results of operations, cash flows or financial 
disclosures.  

In June 2011, the FASB issued ASU No. 2011-05, which amends ASC Topic 220, “Comprehensive Income.” This ASU 
allows  an  entity  to  present  the  total  of  comprehensive  income,  the  components  of  net  income,  and  the  components  of  other 
comprehensive  income  either  in  a  single  continuous  statement  of  comprehensive  income  or  in  two  separate  but  consecutive 
statements. The amendment no longer allows an entity to show changes to other comprehensive income solely through the statement 
of  equity.  For  publicly  traded  entities,  the  guidance  is  effective  for  annual  and  interim  reporting  periods  beginning  on  or  after 
December 15, 2011. In December 2011, the FASB issued ASU No. 2011-12, which defers only those changes in ASU 2011-05 that 
relate to the presentation of reclassification adjustments. Our adoption of this guidance did not have a material impact on our financial 
condition, results of operations, cash flows or financial disclosures.  

Note 2 – Acquisition of FDR Holdings Limited  

On  July 28,  2010,  Noble-Swiss  and  Noble  AM  Merger  Co.,  a  Cayman  Islands  company  and  indirect  wholly-owned 
subsidiary  of  Noble-Swiss  (“Merger  Sub”),  completed  the  acquisition  of  FDR  Holdings  Limited,  a  Cayman  Islands  company 
(“Frontier”). Under the terms of the Agreement and Plan of Merger with Frontier and certain of Frontier’s shareholders, Merger Sub 
merged with and into Frontier, with Frontier surviving as an indirect wholly-owned subsidiary of Noble-Swiss and a wholly-owned 
subsidiary of Noble-Cayman. The Frontier acquisition was for a purchase price of approximately $1.7 billion in cash plus liabilities 
assumed  and  strategically  expanded  and  enhanced  our  global  fleet.  Frontier’s  results  of  operations  were  included  in  our  results 
beginning July 28, 2010. We funded the cash consideration paid at closing using proceeds from our July 2010 offering of senior notes 
and existing cash on hand.  

The pro forma financial information for the year ended December 31, 2010 includes pro forma results for the period prior 
to the closing date of July 28, 2010 and actual results for the period from July 28, 2010 through December 31, 2010. The pro forma 
results are based on historical data and are not intended to be indicative of the results of future operations.

Consolidated joint ventures  

In connection with the Frontier acquisition, we acquired Frontier’s 50 percent interest in two joint ventures, each with a 
subsidiary of Shell, for the construction and operation of the two Bully-class drillships. We have determined that we are the primary

beneficiary.  Accordingly,  we  consolidate  the  entities  in  our  consolidated  financial  statements  after  eliminating  intercompany 
transactions. Shell’s equity interests are presented as noncontrolling interests on our Consolidated Balance Sheets.  

In the first quarter of 2011, the joint venture credit facilities, which had a combined outstanding balance of $693 million, 
were repaid in full through contributions to the joint ventures from Noble and Shell. Shell contributed $361 million in equity to fund 
their portion of the repayment of joint venture credit facilities and related interest rate swaps, which were settled concurrently with the 
repayment and termination of the joint venture credit facilities.  

In January 2011, the Bully joint ventures issued notes to the joint venture partners totaling $70 million. The interest rate 
on these notes was 10%, payable semi-annually in arrears and in kind on June 30 and December 31 commencing in June 2011. The 
purpose  of  these  notes  was  to  provide  additional  liquidity  to  the  joint  ventures  in  connection  with  the  shipyard  construction  of  the 
Bully vessels.  

In April 2011, the Bully joint venture partners entered into a subscription agreement, pursuant to which each partner was 
issued equity in each of the Bully joint ventures in exchange for the cancellation of all outstanding joint venture partner notes. The 
subscription  agreement  converted  all  joint  venture  partner  notes  into  equity  of  the  respective  joint  venture.  The  total  capital 
contributed as a result of these agreements was $146 million, which included $142 million in outstanding notes, plus accrued interest. 
Our portion of the capital contribution, totaling $73 million, was eliminated in consolidation.  

In April 2011, the Bully joint venture partners also entered into capital contribution agreements whereby capital calls up 
to a total of $360 million can be made for funds needed to complete the projects. All contributions under these agreements were made 
during 2011 and the first quarter of 2012. No amounts remain available under these agreements.  

The  combined  carrying  amount  of  the  Bully-class  drillships  at  both  December 31,  2012  and  2011  totaled  $1.4  billion. 
These assets were primarily funded through partner equity contributions. During 2012, these rigs commenced the operating phases of 
their contracts. Current year revenues and net income related to these joint ventures totaled $237 million and $71 million, respectively.

Only those items having a dilutive impact on our basic net income per share are included in diluted net income per share. 
For the years ended December 31, 2012, 2011 and 2010, stock options totaling 1.2 million, 1.1 million and 0.8 million, respectively, 
were excluded from the diluted net income per share calculation as they were not dilutive.  

Note 4- Marketable Securities  
Marketable Equity Securities  

We  have  investments  that  closely  correlate  to  the  investment  elections  made  by  participants  in  the  Noble  Drilling 
Corporation 401(k) Savings Restoration Plan (“Restoration Plan”) in order to mitigate the impact of the investment income and losses 
from  the  Restoration  Plan  on  our  consolidated  financial  statements.  The  value  of  these  investments  held  for  our  benefit  totaled  $6 
million and $5 million at December 31, 2012 and 2011, respectively. These assets were classified as trading securities and carried at 
fair  value  in  “Other  current  assets”  with  the  realized  and  unrealized  gain  or  loss  included  in  “Other  income”  in  the  accompanying 
Consolidated Statements of Income. We recognized a gain of $0.6 million during 2012, a loss of $0.4 million during 2011 and a gain 
of $0.7 million during 2010.  

Note 5- Receivables from Customers  

At December 31, 2012, we had receivables of approximately $14 million related to the Noble Max Smith, which are being 
disputed by our customer, Pemex Exploracion y Produccion (“Pemex”). These receivables have been classified as long-term and are 
included  in  “Other  assets”  on  our  Consolidated  Balance  Sheet.  The  disputed  amount  relates  to  lost  revenues  for  downtime  that 
occurred  after  our  rig  was  damaged  when  one  of  Pemex’s  supply  boats  collided  with  our  rig  in  2010.  In  January  2012,  we  filed  a 
lawsuit against Pemex in Mexican court seeking recovery of these amounts. While we can make no assurances as to the outcome of 
this dispute, we believe we are entitled to the disputed amounts.

Credit Facilities and Commercial Paper Program  

Noble currently has a maximum available capacity of $800 million on our credit facility maturing in 2015 and $1.5 billion 
on our credit facility maturing in 2017 (together referred to as the “Credit Facilities”). Our total debt related to the Credit Facilities and 
our commercial paper program was $340 million at December 31, 2012 as compared to $975 million at December 31, 2011. During 
2012, we undertook a series of transactions that increased our liquidity. The following summarizes the recent activity regarding our 
Credit Facilities:  

• 

in  June  2012,  we  replaced  our  $575  million  credit  facility  scheduled  to  mature  in  2013,  with  a  new  $1.2 
billion credit facility, which matures in 2017;

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

•  

•  

in  September  2012,  we  established  a  commercial  paper  program,  which  will  allow  us  to  issue  up  to  $1.8 
billion  in  unsecured  commercial  paper  notes. Amounts  issued  under  the  commercial  paper  program  are 
supported by the unused committed capacity under our Credit Facilities and, as such, are classified as long-
term on our Consolidated Balance Sheet; and  
in January 2013, we increased the maximum amount available under our Credit Facilities from $1.8 billion 
to  $2.3  billion.  The  maximum  amount  available  under  our  credit  facility  maturing  in  2015  was  increased 
from $600 million to $800 million and the maximum amount available under our credit facility maturing in 
2017 was increased from $1.2 billion to $1.5 billion.  

The  Credit  Facilities  provide  us  with  the  ability  to  issue  up  to  $375  million  in  letters  of  credit  in  the  aggregate.  The 
issuance of letters of credit does not increase our borrowings outstanding under the Credit Facilities, but it does reduce the amount 
available. At December 31, 2012, we had no letters of credit issued under the Credit Facilities.  

Senior Unsecured Notes  

Our  total  debt  related  to  senior  unsecured  notes  was  $4.3  billion  at  December 31,  2012  as  compared  to  $3.1  billion  at 
December 31,  2011.  The  increase  in  debt  is  a  result  of  the  issuance  of  $1.2  billion  aggregate  principal  amount  of  senior  notes  in 
February 2012, which we issued through our indirect wholly-owned subsidiary, Noble Holding International Limited (“NHIL”). These 
senior notes were issued in three separate tranches, with $300 million of 2.50% Senior Notes due 2017, $400 million of 3.95% Senior 
Notes due 2022, and $500 million of 5.25% Senior Notes due 2042. The weighted average coupon of all three tranches is 4.13%. The 
net proceeds of approximately $1.19 billion, after expenses, were primarily used to repay the then outstanding balance on our Credit 
Facilities. 

In  February  2011,  we  issued,  through  NHIL,  $1.1  billion  aggregate  principal  amount  of  senior  notes  in  three  separate 
tranches, comprising $300 million of 3.05% Senior Notes due 2016, $400 million of 4.625% Senior Notes due 2021, and $400 million 
of  6.05%  Senior  Notes  due  2041.  The  weighted  average  coupon  of  all  three  tranches  is  4.71%.  A  portion  of  the  net  proceeds  of 
approximately  $1.09  billion,  after  expenses,  was  used  to  repay  the  then  outstanding  balance  on  our  revolving  credit  facility  and  to 
repay our portion of outstanding debt under the joint venture credit facilities discussed below.  

Our  5.875%  Senior  Notes  mature  during  the  second  quarter  of  2013.  We  anticipate  using  availability  under  our  Credit 
Facilities or commercial paper program to repay the outstanding balance; therefore, we continue to report the balance as long-term at 
December 31, 2012.  

Covenants  

The  Credit  Facilities  are  guaranteed  by  our  indirect  wholly-owned  subsidiaries,  NHIL  and  Noble  Drilling  Corporation 
(“NDC”).  The  covenants  and  events  of  default  under  the  Credit  Facilities  are  substantially  similar,  and  each  facility  contains  a 
covenant that limits our ratio of debt to total tangible capitalization, as defined in the Credit Facilities, to 0.60. At December 31, 2012, 
our  ratio  of  debt  to  total  tangible  capitalization  was  less  than  0.36.  We  were  in  compliance  with  all  covenants  under  the  Credit 
Facilities as of December 31, 2012.  

In  addition  to  the  covenants  from  the  Credit  Facilities  noted  above,  the  indentures  governing  our  outstanding  senior 
unsecured notes contain covenants that place restrictions on certain merger and consolidation transactions, unless we are the surviving 
entity or the other party assumes the obligations under the indenture, and on the ability to sell or transfer all or substantially all of our 
assets. In addition, there are restrictions on incurring or assuming certain liens and sale and lease-back transactions. At December 31, 
2012, we were in compliance with all our debt covenants. We continually monitor compliance with the covenants under our notes and, 
based on our expectations for 2013, expect to remain in compliance during the year.  

Joint Venture Debt  

In the first quarter of 2011, the joint venture credit facilities, which had a combined outstanding balance of $693 million, 
were repaid in full through contributions to the joint ventures from Noble and Shell. Shell contributed $361 million in equity to fund 
their portion of the repayment of joint venture credit facilities and related interest rate swaps, which were settled concurrently with the 
repayment and termination of the joint venture credit facilities.  

In January 2011, the Bully joint ventures issued notes to the joint venture partners totaling $70 million. The interest rate 
on these notes was 10%, payable semi-annually in arrears, and in kind, on June 30 and December 31 commencing in June 2011. The

NOBLE CORPORATION (NOBLE-CAYMAN) AND SUBSIDIARIES

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

purpose  of  these  notes  was  to  provide  additional  liquidity  to  the  joint  ventures  in  connection  with  the  shipyard  construction  of  the 
Bully vessels.  

In April 2011, the Bully joint venture partners entered into a subscription agreement, pursuant to which each partner was 
issued equity in each of the Bully joint ventures in exchange for the cancellation of all outstanding joint venture partner notes. The 
subscription agreement has the effect of converting all joint venture partner notes into equity of the respective joint venture. The total 
capital contributed as a result of these agreements was $146 million, which included $142 million in outstanding notes, plus accrued 
interest. Our portion of the capital contribution, totaling $73 million, was eliminated in consolidation.  

Other  

At December 31, 2012, we had letters of credit of $48 million and performance and tax assessment bonds totaling $264 
million  supported  by  surety  bonds  outstanding.  Additionally,  certain  of  our  subsidiaries  issue  guarantees  to  the  temporary  import 
status  of  rigs  or  equipment  imported  into  certain  countries  in  which  we  operate. These  guarantees  are  issued  in-lieu  of  payment  of 
custom, value added or similar taxes in those countries.

In  May  2013,  our  5.875%  senior  notes  mature.  We  anticipate  using  availability  on  our  Credit  Facilities  or  commercial  paper 
program to repay the outstanding balance; therefore, we have shown the entire balance as long-term on our December 31, 2012 
Consolidated Balance Sheet.  

(2)  Amounts outstanding under our commercial paper program mature during 2013. As amounts issued under the commercial paper 
program  are  supported  by  the  unused  committed  capacity  under  our  Credit  Facilities,  they  are  classified  as  long-term  on  our 
Consolidated Balance Sheet at December 31, 2012.  

Fair Value of Financial Instruments  

Fair  value  represents  the  amount  at  which  an  instrument  could  be  exchanged  in  a  current  transaction  between  willing 
parties. The estimated fair value of our senior notes was based on the quoted market prices for similar issues or on the current rates 
offered to us for debt of similar remaining maturities (Level 2 measurement). The following table presents the estimated fair value of 
our long-term debt as of December 31, 2012 and 2011.

Shares authorized for issuance by Noble-Swiss at December 31, 2012 totaled 266.2 million shares and include 0.6 million 
shares  held  in  treasury  by  Noble-Swiss  and  12.8 million  treasury  shares  held  by  a  wholly-owned  subsidiary.  Repurchased  treasury 
shares are recorded at cost, and relate to shares surrendered by employees for taxes payable upon the vesting of restricted stock.  

Our  Board  of  Directors  may  further  increase  Noble-Swiss’  share  capital  through  the  issuance  of  up  to  133.1 million 
authorized  shares  without  obtaining  shareholder  approval.  The  issuance  of  these  authorized  shares  is  subject  to  certain  conditions 
regarding  their  use.  The  current  authority  to  issue  these  shares  will  expire  in  April  2013.  We  will  recommend  at  the  2013  annual 
general meeting of shareholders that shareholders extend this authority for two years until April 2015.  

In April 2012, our shareholders approved the payment of a dividend aggregating $0.52 per share to be paid in four equal 
installments.  As  of  December 31,  2012,  we  had  $66  million  of  dividends  payable  outstanding  on  this  obligation.  Any  additional 
issuances of shares would further increase our obligation.  

Share Repurchases  

Share  repurchases  made  in  the  open  market  are  made  pursuant  to  the  share  repurchase  program,  which  our  Board  of 
Directors  authorized  and  adopted.  At  December 31,  2012,  6.8 million  shares  remained  available  under  this  authorization.  Future 
repurchases  will  be  subject  to  the  requirements  of  Swiss  law,  including  the  requirement  that  we  and  our  subsidiaries  may  only 
repurchase  shares  if  and  to  the  extent  that  sufficient  freely  distributable  reserves  are  available.  Also,  the  aggregate  par  value  of  all 
registered shares held by us and our subsidiaries, including treasury shares, may not exceed 10 percent of our registered share capital 
without shareholder approval. Our existing share repurchase program received the required shareholder approval prior to completion 
of our 2009 Swiss migration transaction. Share repurchases for each of the three years ended December 31, 2012 are as follows:

Stock Plans  

The  Noble  Corporation  1991  Stock  Option  and  Restricted  Stock  Plan,  as  amended  (the  “1991  Plan”),  provides  for  the 
granting of options to purchase our shares, with or without stock appreciation rights, and the awarding of restricted shares or units to

employees under the 1991 Plan.  

Prior  to  October 25,  2007,  the  Noble  Corporation  1992  Nonqualified  Stock  Option  and  Share  Plan  for  Non-Employee 
Directors (the “1992 Plan”) provided for the granting of nonqualified stock options to our non-employee directors. We granted options 
at fair  market  value on the grant date. The options are exercisable from time to time over a period commencing one  year from the 
grant date and ending on the expiration of 10 years from the grant date, unless terminated sooner as described in the 1992 Plan. On 
October 25, 2007, the 1992 Plan was amended and restated to, among other things, eliminate grants of stock options to non-employee 
directors and modify the annual award of restricted shares from a fixed number of restricted shares to an annually-determined variable 
number of restricted or unrestricted shares. The 1992 Plan limits the total number of shares issuable under the plan to 2.0 million. As 
of December 31, 2012, we had 0.6 million shares remaining available for award to non-employee directors under the 1992 Plan.

The fair value of each option is estimated on the date of grant using a Black-Scholes pricing model. Assumptions used in 
the valuation are shown  in the table above. The expected term of options granted represents the period of time that the options are 
expected  to  be  outstanding  and  is  derived  from  historical  exercise  behavior,  current  trends  and  values  derived  from  lattice-based 
models. Expected volatilities are based on implied volatilities of traded options on our shares, historical volatility of our shares, and 
other factors. The expected dividend  yield is based on historical yields on the date of grant. The risk-free rate is based on the U.S. 
Treasury yield curve in effect at the time of grant.  

A  summary  of  the  status  of  our  non-vested  stock  options  at  December 31,  2012,  and  changes  during  the  year  ended

At December 31, 2012, there was $4 million of total unrecognized compensation cost remaining for option grants awarded 
under  the  1991  Plan.  We  attribute  the  service  period  to  the  vesting  period  and  the  unrecognized  compensation  is  expected  to  be 
recognized over a weighted-average period of 1.7 years. Compensation cost recognized during the years ended December 31, 2012, 
2011 and 2010 related to stock options totaled $4 million, $3 million and $3 million, respectively.  

We  issue  new  shares  to  meet  the  share  requirements  upon  exercise  of  stock  options.  We  have  historically  repurchased 

shares in the open market from time to time, which minimizes the dilutive effect of share-based compensation.  

Restricted Stock  

We have awarded both time-vested restricted stock and market based performance-vested restricted stock under the 1991 
Plan. The time-vested restricted stock awards generally vest over a three  year period. The number of performance-vested restricted 
shares which vest will depend on the degree of achievement of specified corporate performance criteria over a three-year performance 
period. These criteria are strictly market based criteria as defined by FASB standards.  

The time-vested restricted stock is valued on the date of award at our underlying share price. The total compensation for 
shares  that  ultimately  vest  is  recognized  over  the  service  period. The  shares  and  related  par  value  are  recorded  when  the  restricted 
stock  vests  and  additional  paid-in  capital  is  adjusted  as  the  share-based  compensation  cost  is  recognized  for  financial  reporting 
purposes.  

The  market  based  performance-vested  restricted  stock  is  valued  on  the  date  of  grant  based  on  the  estimated  fair  value. 
Estimated  fair  value  is  determined  based  on  numerous  assumptions,  including  an  estimate  of  the  likelihood  that  our  stock  price 
performance  will  achieve  the  targeted  thresholds  and  the  expected  forfeiture  rate.  The  fair  value  is  calculated  using  a  Monte  Carlo 
Simulation Model. The assumptions  used to  value the performance-vested restricted  stock awards  include  historical  volatility, risk-
free interest rates, and expected dividends over a time period commensurate with the remaining term prior to vesting, as follows:  

Valuation assumptions: 
Expected volatility .....................................................................................
Expected dividend yield.............................................................................

Additionally, similar assumptions were made for each of the companies included in the defined index and the peer group

amounts shown.  

At December 31, 2012 there was $30 million of total unrecognized compensation cost related to the time-vested restricted 
shares which is expected to be recognized over a remaining weighted-average period of 1.6 years. The total award-date fair value of 
time-vested restricted shares vested during the year ended December 31, 2012 was $20 million.  

At December 31, 2012, there was $8 million of total unrecognized compensation cost related to the performance-vested 
restricted  shares  which  is  expected  to  be  recognized  over  a  remaining  weighted-average  period  of  1.5  years.  The  total  potential 
compensation  for  performance-vested  restricted  stock  is  recognized  over  the  service  period  regardless  of  whether  the  performance 
thresholds are ultimately achieved. During the year ended December 31, 2012, 374,864 performance-vested shares for the 2009-2011 
performance  period  were  forfeited.  In  February  2013,  all  performance-vested  shares  for  the  2010-2012  performance  period  were 
forfeited.  

Share-based amortization recognized during the years ended December 31, 2012, 2011 and 2010 related to all restricted 
stock totaled $36 million ($31 million net of income tax), $32 million ($28 million net of income tax) and $35 million ($30 million net 
of income tax), respectively. Capitalized share-based amortization totaled approximately $1 million for each year in 2012, 2011 and

Note 10- Gain on Contract Settlements/Extinguishments, Net  

During the second quarter of 2012, we received approximately $5 million from the settlement of a claim relating to the 
Noble  David  Tinsley,  which  had  experienced  a  “punch-through”  while  being  positioned  on  location  in  2009.  We  had  originally 
recorded  a  $17  million  charge  during  2009  related  to  this  incident.  Additionally,  during  the  second  quarter  of  2012,  we  settled  an 
action against certain  vendors for damages sustained during Hurricane Ike. We recognized a net gain of approximately $28  million 
related to this settlement. We also resolved all outstanding matters with Anadarko Petroleum Company (“Anadarko”) related to the 
previously disclosed force majeure action, Hurricane Ike matters and receivables relating to the Noble Amos Runner.  

In January 2011, we announced the signing of a MOU with Petrobras regarding operations in Brazil. Under the terms of 
the MOU, we agreed to substitute the Noble Phoenix, then under contract with Shell in Southeast Asia, for the Noble Muravlenko. In 
connection with the cancellation of the contract on the Noble Phoenix, we recognized a non-cash gain of approximately $52.5 million 
during the first quarter of 2011, which represented the unamortized fair value of the in-place contract at acquisition. As a result of the 
substitution, we reached a decision not to proceed with the previously announced reliability upgrade to the Noble Muravlenko that was 
scheduled to take place in 2013, and therefore, incurred a non-cash charge of approximately $32.6 million related to the termination of 
outstanding shipyard contracts. The substitution was completed during the fourth quarter of 2012.  

In February 2011, the outstanding balances of the Bully joint venture credit facilities, which totaled $693 million,  were 
repaid  in  full  and  the  credit  facilities  terminated  using  a  portion  of  the  proceeds  from  our  February  2011  debt  offering  and  equity 
contributions from our joint venture partner. In addition, the related interest rate swaps were settled and terminated concurrent with the 
repayment and termination of the credit facilities. As a result of these transactions, we recognized a gain of approximately $1.3 million 
during the first quarter of 2011.  

Note 11- Loss on Impairment  

During the second quarter of 2012, our submersible rig fleet, consisting of two cold stacked rigs, was partially impaired 
due to the declining market outlook for drilling services for this rig type. We estimated the fair value of the rigs based on the salvage 
value of the rigs and a recent transaction involving a similar unit owned by a peer company (Level 2 fair value measurement). Based 
on these estimates, we recognized a charge of approximately $13 million in 2012.  

Also,  during  the  second  quarter  of  2012,  we  determined  that  certain  corporate  assets  were  partially  impaired  due  to  a 
declining market for, and the potential disposal of, the assets. We estimated the fair value of the assets based on recent transactions 
involving  similar  units  in  the  market  (Level  2  fair  value  measurement).  Based  on  these  estimates,  we  recognized  a  charge  of 
approximately $7 million in 2012.  

Note 12- Income Taxes  

Noble-Swiss  is  exempt  from  Swiss  cantonal  and  communal  income  tax  on  its  worldwide  income,  and  is  also  granted 
participation  relief  from  Swiss  federal  tax  for  qualifying  dividend  income  and  capital  gains  related  to  the  sale  of  qualifying 
participations.  It  is  expected  that  the  participation  relief  will  result  in  a  full  exemption  of  participation  income  from  Swiss  federal 
income tax.

December 31, 2010, respectively. There were no transactions recorded directly to equity for the year ended December 31, 2012.

If these reserves of $125 million are not realized, the provision for income taxes will be reduced by $125 million.  

We  include,  as  a  component  of  our  “Income  tax  provision”,  potential  interest  and  penalties  related  to  recognized  tax 
contingencies within our global operations. Interest and penalties resulted in an income tax expense of $5 million in 2012, an income 
tax benefit of $5 million in 2011 and an income tax expense of $6 million in 2010.  

It  is  reasonably  possible  that  our  existing  liabilities  related  to  our  reserve  for  uncertain  tax  positions  may  increase  or 
decrease in the next twelve months primarily due to the completion of open audits or the expiration of statutes of limitation. However, 
we cannot reasonably estimate a range of changes in our existing liabilities due to various uncertainties, such as the unresolved nature 
of various audits.  

We conduct business globally and, as a result, we file numerous income tax returns in the U.S. and non-U.S. jurisdictions. 
In  the  normal  course  of  business  we  are  subject  to  examination  by  taxing  authorities  throughout  the  world,  including  major 
jurisdictions such as Brazil, India, Mexico, Nigeria, Norway, Qatar, Saudi Arabia, Switzerland, the United Kingdom and the United 
States.  We  are  no  longer  subject  to  U.S.  Federal  income  tax  examinations  for  years  before  2008  and  non-U.S.  income  tax 
examinations for years before 2002.

Noble-Swiss conducts substantially all of its business through Noble-Cayman and its subsidiaries. Earnings are taxable in 
Switzerland at the Swiss statutory rate of 8.5 percent. This statutory rate is not material due to our participation exemption, and the 
Cayman Islands does not impose a corporate income tax. A reconciliation of tax rates outside of Switzerland and the Cayman Islands 
to our Noble-Swiss effective rate is shown below:

In 2012, we generated and fully utilized $22 million of U.S. foreign tax credits. In 2011, we generated and fully utilized 

$21 million of U.S. foreign tax credits. In 2010, we fully utilized our foreign tax credits of $17 million.  

Deferred income taxes and the related dividend withholding taxes have not been provided on approximately $2.1 billion 
of undistributed earnings of our subsidiaries. We consider such earnings to be permanently reinvested. Due to complexities in the tax 
laws  and  the  manner  of  repatriation,  it  is  not  practicable  to  estimate  the  amount  of  deferred  income  taxes  associated  with  these 
unremitted earnings. If such earnings were to be distributed, we would be subject to tax, which would have a material impact on our 
results of operations.  

Note 13- Employee Benefit Plans  
Defined Benefit Plans  

We have two U.S. noncontributory defined benefit pension plans: one which covers certain salaried employees and one 
which covers certain hourly employees, whose initial date of employment is prior to August 1, 2004 (collectively referred to as our 
“qualified U.S. plans”). These plans are governed by the Noble Drilling Corporation Retirement Trust (the “Trust”). The benefits from 
these plans are based primarily on years of service and, for the salaried plan, employees’ compensation near retirement. These plans 
qualify under the Employee Retirement Income Security Act of 1974 (“ERISA”), and our funding policy is consistent with funding 
requirements of ERISA and other applicable laws and regulations. We make cash contributions, or utilize credit balances available to 
us under the plan, for the qualified U.S. plans when required. The benefit amount that can be covered by the qualified U.S. plans is 
limited  under  ERISA  and  the  Internal  Revenue  Code  (“IRC”)  of  1986.  Therefore,  we  maintain  an  unfunded,  nonqualified  excess 
benefit  plan  designed  to  maintain  benefits  for  all  employees  at  the  formula  level  in  the  qualified  salary  U.S.  plan.  We  refer  to  the 
qualified U.S. plans and the excess benefit plan collectively as the “U.S. plans”.  

Each  of  Noble  Drilling  (Land  Support)  Limited,  Noble  Enterprises  Limited  and  Noble  Drilling  (Nederland)  B.V.,  all 
indirect, wholly-owned subsidiaries of Noble-Swiss, maintains a pension plan which covers all of its salaried, non-union employees 
(collectively  referred  to  as  our  “non-U.S.  plans”).  Benefits  are  based  on  credited  service  and  employees’  compensation  near 
retirement, as defined by the plans.  

A reconciliation of the changes in projected benefit obligations (“PBO”) for our non-U.S. and U.S. plans is as follows:  

Benefit obligation at beginning of year ....................................
Service cost .....................................................................
Interest cost .....................................................................

The discount rate  used to calculate the  net present value of  future benefit obligations  for our U.S. plan is based on the 
average  of  current  rates  earned  on  long-term  bonds  that  receive  a  Moody’s  rating  of  “Aa”  or  better.  We  have  determined  that  the 
timing and amount of expected cash outflows on our plan reasonably match this index. For non-U.S. plans, the discount rates used to 
calculate the net present value of future benefit obligations are determined by using a yield curve of high quality bond portfolios with 
an average maturity approximating that of the liabilities.  

We employ third-party consultants for our U.S. and non-U.S. plans that use a portfolio return model to assess the initial 
reasonableness of the expected long-term rate of return on plan assets. To develop the expected long-term rate of return on assets, we 
considered  the  current  level  of  expected  returns  on  risk  free  investments  (primarily  government  bonds),  the  historical  level  of  risk 
premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns of each asset 
class. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected long-
term rate of return on assets for the portfolio.  

Defined Benefit Plans—Plan Assets  
Non-U.S. Plans  

Both the Noble Enterprises Limited and Noble Drilling (Nederland) B.V. pension plans have a targeted asset allocation of 
100 percent debt securities. The investment objective for the Noble Enterprises Limited U.S. Dollar plan assets is to earn a favorable 
return against the Citigroup World Governmental Bond Index  for all  maturities greater than one  year. The investment objective for 
both  the  Noble  Enterprises  Limited  (“NEL”)  and  the  Noble  Drilling  (Nederland)  B.V.  (“NDNBV”)  Euro  plan  assets  is  to  earn  a 
favorable  return  against  the  Barclays  Capital  Euro  Aggregate  Unhedged  index  and  the  Customized  Benchmark  for  Long  Duration 
Fund for all maturities greater than one year. We evaluate the performance of these plans on an annual basis. 

The Noble Drilling (Land Support) Limited pension plan has a target asset allocation of 70 percent equity securities and 
30  percent  debt  securities.  The  investment  objective  of  the  plan,  as  adopted  by  the  plan’s  trustees,  is  to  achieve  a  favorable  return 
against a benchmark of blended United Kingdom market indices. By achieving this objective, the trustees believe the plan will be able 
to avoid significant volatility in the contribution rate and provide sufficient plan assets to cover the plan’s benefit obligations were the 
plan to be liquidated. To achieve these objectives, the trustees have given the plan’s investment managers full discretion in the day-to-
day  management  of  the  plan’s  assets.  The  plan’s  assets  are  invested  with  two  investment  managers.  The  performance  objective 
communicated to one of these investment managers is to exceed a blend of FTSE A Over 15 Year Gilts index and iBoxx Sterling Non 
Gilts  index  by  1.25  percent  per  annum.  The  performance  objective  communicated  to  the  other  investment  manager  is  to  exceed  a 
blend of FTSE’s All Share index, North America index, Europe index and Pacific Basin index by 1.00 to 2.00 percent per annum. This 
investment  manager  is  prohibited  by  the  trustees  from  investing  in  real  estate.  The  trustees  meet  with  the  investment  managers 
periodically to review and discuss their investment performance.

For the year ended December 31, 2011, we presented the $20 million in fixed income securities in the December 31, 2011 
table  above  as  a  Level  1  measurement. While  the  underlying  investments  are  traded  in  active  markets,  which  is  a  Level  1 
measurement, the funds  we own  the investments through are not themselves actively traded, and therefore are being presented as a 
Level 2 measurement at both December 31, 2012 and 2011. The change in presentation for December 31, 2011 does not affect the fair 
value of the investment, nor does it have a material impact on our funding status as of December 31, 2011.

At  December 31,  2012,  assets  of  both  NEL  and  NDNBV  are  invested  in  instruments  that  are  similar  in  form  to  a 
guaranteed insurance contract. There are no observable market values for these assets (Level 3); however, the amounts listed as plan 
assets  were  materially  similar  to  the  anticipated  benefit  obligations  that  were  anticipated  under  the  plan. Amounts  were  therefore 
calculated  using  actuarial  assumptions  completed  by  third-party  consultants  employed  by  Noble. The  following  table  details  the

U.S. Plans  

The Trust invests in equity securities, fixed income debt securities, and cash equivalents and other short-term investments. 

The Trust may invest in these investments directly or through pooled vehicles, including mutual funds.  

The  Company’s  overall  investment  strategy,  or  target  range,  is  to  achieve  a  mix  of  approximately  65  percent  in  equity 
securities, 32 percent in debt securities and 3 percent in cash holdings. Actual results may deviate from the target range, however any 
deviation from the target range of asset allocations must be approved by the Trust’s governing committee.  

The performance objective of the Trust is to outperform the return of the Total Index Composite as constructed to reflect 
the target allocation weightings for each asset class. This objective should be met over a market cycle, which is defined as a period not 
less than three years or more than five years. U.S. equity securities (common stock, convertible preferred stock and convertible bonds) 
should achieve a total return (after fees) that exceeds the total return of an appropriate market index over a full market cycle of three to 
five years. Non-U.S. equity securities (common stock, convertible preferred stock and convertible bonds), either from developed or 
emerging  markets,  should achieve a total return (after  fees) that exceeds the total return of an appropriate market index over a  full 
market cycle of three to five years. Fixed income debt securities should achieve a total return (after fees) that exceeds the total return 
of  an  appropriate  market  index  over  a  full  market  cycle  of  three  to  five  years.  Cash  equivalent  and  short-term  investments  should 
achieve  relative  performance  better  than  the  90-day  Treasury  bills.  When  mutual  funds  are  used  by  the  Trust,  those  mutual  funds 
should achieve a total return  that equals or exceeds the total return of each fund’s appropriate Lipper or Morningstar peer category 
over a full market cycle of three to five years. Lipper and Morningstar are independent mutual fund rating and information services.  

For investments in equity securities, no individual options or financial futures contracts are purchased unless approved in 
writing  by  the  Trust’s  governing  committee.  In  addition,  no  private  placements  or  purchases  of  venture  capital  are  allowed.  The 
maximum  commitment  to  a  particular  industry,  as  defined  by  Standard &  Poor’s,  may  not  exceed  20  percent.  The  Trust’s  equity 
managers vote all proxies in the best interest of the Trust without regards to social issues. The Trust’s governing committee reserves 
the right to comment on and exercise control over the response to any individual proxy solicitation.  

For  fixed  income  debt  securities,  corporate  bonds  purchased  are  primarily  limited  to  investment  grade  securities  as 
established by Moody’s or Standard & Poor’s. At no time shall the lowest investment grade make up more than 20 percent of the total 
market value of the Trust’s fixed income holdings. The total fixed income exposure from any single non-government or government 
agency issuer shall not exceed 10 percent of the Trust’s fixed income holdings. The average duration of the total portfolio shall not 
exceed  seven  years.  All  interest  and  principal  receipts  are  swept,  as  received,  into  an  alternative  cash  management  vehicle  until 
reallocated in accordance with the Trust’s core allocation.  

For investments in mutual funds, the assets of the Trust are subject to the guidelines and limits imposed by such mutual 

fund’s prospectus and the other governing documentation at the fund level.  

For  investments  in  cash  equivalent  and  short-term  investments,  the  Trust  utilizes  a  money  market  mutual  fund  which 
invests  in  U.S.  government  and  agency  obligations,  repurchase  agreements  collateralized  by  U.S.  government  or  agency  securities, 
commercial  paper,  bankers’  acceptances,  certificate  of  deposits,  delayed  delivery  transactions,  reverse  repurchase  agreements,  time

deposits and Euro obligations. Bankers’ acceptances shall be made in larger banks (ranked by assets) rated “Aa” or better by Moody’s 
and in conformance with all FDIC regulations concerning capital requirements.  

Equity securities include our shares in the amounts of $4 million (2.3 percent of total U.S. plan assets) and $3 million (2.4 

percent of total U.S. plan assets) at December 31, 2012 and 2011, respectively.

For the year ended December 31, 2011, we presented the $17 million in equity securities in the December 31, 2011 table 
above as a Level 1 measurement. While the underlying investments are traded in active markets, which is a Level 1 measurement, the 
funds we own the investments through are not themselves actively traded, and therefore are being presented as a Level 2 measurement 
at  both  December  31,  2012  and  2011. The  change  in  presentation  for  December  31,  2011  does  not  affect  the  fair  value  of  the 
investment, nor does it have a material impact on our funding status as of December 31, 2011.  

As of December 31, 2012, no single security made up more than 10 percent of total assets of either the U.S. or the Non-

U.S. plans.  

Defined Benefit Plans—Cash Flows  

In 2012, we made total contributions of $6 million and $11 million to our non-U.S. and U.S. pension plans, respectively. 
In 2011, we made total contributions of $6 million and $5 million to our non-U.S. and U.S. pension plans, respectively. In 2010, we 
made total contributions of $6 million and $10 million to our non-U.S. and U.S. pension plans, respectively. We expect our aggregate 
minimum  contributions  to  our  non-U.S.  and  U.S.  plans  in  2013,  subject  to  applicable  law,  to  be  $8  million  and  $10  million, 
respectively. We continue to monitor and evaluate funding options based upon market conditions and may increase contributions at 
our discretion.

We  sponsor  the  Restoration  Plan,  which  is  a  nonqualified,  unfunded  employee  benefit  plan  under  which  certain  highly 
compensated  employees  may  elect  to  defer  compensation  in  excess  of  amounts  deferrable  under  our  401(k)  savings  plan.  The 
Restoration  Plan  has  no  assets,  and  amounts  withheld  for  the  Restoration  Plan  are  kept  by  us  for  general  corporate  purposes.  The 
investments  selected  by  employees  and  associated  returns  are  tracked  on  a  phantom  basis.  Accordingly,  we  have  a  liability  to  the 
employee  for  amounts  originally  withheld  plus  phantom  investment  income  or  less  phantom  investment  losses.  We  are  at  risk  for 
phantom investment income and, conversely, benefit should phantom investment losses occur. At December 31, 2012 and 2011, our 
liability for the Restoration Plan was $7 million and $6 million, respectively, and is included in “Accrued payroll and related costs.”  

In  2005  we  enacted  a  profit  sharing  plan,  the  Noble  Drilling  Corporation  Profit  Sharing  Plan,  which  covers  eligible 
employees, as defined. Participants in the plan become fully vested in the plan after five years of service, or three years beginning in 
2007.  Profit  sharing  contributions  are  discretionary,  require  Board  of  Directors  approval  and  are  made  in  the  form  of  cash. 
Contributions recorded related to this plan totaled $4 million, $2 million and $2 million in 2012, 2011 and 2010, respectively.  

We sponsor a 401(k) savings plan and other plans for the benefit of our employees. The cost of maintaining these plans 
aggregated $84 million, $61 million and $45 million in 2012, 2011 and 2010, respectively. We do not provide post-retirement benefits 
(other than pensions) or any post-employment benefits to our employees.  

Note 14- Derivative Instruments and Hedging Activities  

We  periodically  enter  into  derivative  instruments  to  manage  our  exposure  to  fluctuations  in  interest  rates  and  foreign 
currency exchange rates. We have documented policies and procedures to monitor and control the use of derivative instruments. We 
do not engage in derivative transactions for speculative or trading purposes, nor were we a party to leveraged derivatives. During the 
period, we maintained certain foreign currency forward contracts that did not qualify under the FASB standards for hedge accounting 
treatment and therefore, changes in fair values were recognized as either income or loss in our consolidated income statement.  

For  foreign  currency  forward  contracts,  hedge  effectiveness  is  evaluated  at  inception  based  on  the  matching  of  critical 
terms between derivative contracts and the hedged item. For interest rate swaps, we evaluate all material terms between the swap and 
the  underlying  debt  obligation,  known  in  FASB  standards  as  the  “long-haul  method”.  Any  change  in  fair  value  resulting  from 
ineffectiveness is recognized immediately in earnings. No income or loss was recognized during 2012 due to hedge ineffectiveness. 
During 2011 and 2010, we recognized a loss of $1.2 million and $0.3 million, respectively, in other income due to interest rate swap 
hedge ineffectiveness.  

Cash Flow Hedges  

Our  North  Sea  and  Brazil  operations  have  a  significant  amount  of  their  cash  operating  expenses  payable  in  local 
currencies. To limit the potential risk of currency fluctuations, we have historically maintained short-term forward contracts settling 
monthly  in  their  respective  local  currencies.  At  December 31,  2012,  we  had  no  outstanding  derivative  contracts.  At  December 31, 
2011  total  unrealized  loss  related  to  forward  contracts  was  $3  million,  which  was  recorded  as  part  of  AOCL  in  our  Consolidated 
Balance Sheet.  

Our two joint ventures had maintained interest rate swaps which were classified as cash flow hedges. The purpose of these 
hedges  was  to  satisfy  bank  covenants  of  the  then  outstanding  credit  facilities  and  to  limit  exposure  to  changes  in  interest  rates.  In 
February  2011,  the  outstanding  balances  of  the  joint  venture  credit  facilities  and  the  related  interest  rate  swaps  were  settled  and 
terminated. As a result of these transactions, we recognized a gain of $1 million during the year ended December 31, 2011.

Foreign Currency Forward Contracts  

The Bully 2 joint venture maintained foreign currency forward contracts to help mitigate the risk of currency fluctuation 
of the Singapore Dollar for the construction of the Noble Bully II drillship. These contracts were not designated for hedge accounting 
treatment under FASB standards, and therefore, changes in fair values were recognized as either income or loss in our Consolidated 
Income Statement. These contracts are referred to as non-designated derivatives in the tables to follow, and all were settled during the 
first quarter of 2011. For the year ended December 31, 2011, we recognized a loss of $0.5 million related to these foreign currency 
forward contracts.  

Financial Statement Presentation

The derivative instruments have been valued using actively quoted prices and quotes obtained from the counterparties to 
the derivative agreements. Our cash and cash equivalents, accounts receivable and accounts payable are by their nature short-term. As 
a result, the carrying values included in the accompanying Consolidated Balance Sheets approximate fair value.  

Concentration of Credit Risk  

The market for our services is the offshore oil and gas industry, and our customers consist primarily of government-owned 
oil companies, major integrated oil companies and independent oil and gas producers. We perform ongoing credit evaluations of our 
customers  and  generally  do  not  require  material  collateral.  We  maintain  reserves  for  potential  credit  losses  when  necessary.  Our 
results  of  operations  and  financial  condition  should  be  considered  in  light  of  the  fluctuations  in  demand  experienced  by  drilling 
contractors  as  changes  in  oil  and  gas  producers’  expenditures  and  budgets  occur.  These  fluctuations  can  impact  our  results  of 
operations  and  financial  condition  as  supply  and  demand  factors  directly  affect  utilization  and  dayrates,  which  are  the  primary 
determinants of our net cash provided by operating activities.  

In  2012,  two  customers  combined  for  approximately  46  percent  of  our  consolidated  operating  revenues.  In  2011,  three 
customers  combined  for  approximately  57  percent  of  our  consolidated  operating  revenues.  In  2010,  three  customers  accounted  for 
approximately 50 percent of consolidated operating revenues. No other customer accounted for more than 10 percent of consolidated 
operating revenues in 2012, 2011 and 2010.  

Note 16- Commitments and Contingencies  

The Noble Homer Ferrington was under contract with a subsidiary of ExxonMobil Corporation (“ExxonMobil”), which 
entered into an assignment agreement with BP for a two-well farmout of the rig in Libya after successfully drilling two wells with the 
rig for ExxonMobil. In August 2010, BP attempted to terminate the assignment agreement claiming that the rig was not in the required 
condition, and ExxonMobil informed us that we must look to BP for payment of the dayrate during the assignment period. In August 
2010, we initiated arbitration proceedings under the drilling contract against both BP and ExxonMobil. We do not believe BP had the 
right  to  terminate  the  assignment  agreement  and  believe  the  rig  was  ready  to  operate  under  the  drilling  contract.  The  rig  operated 
under  farmout  arrangements  from  March  2011  to  the  conclusion  of  the  contract  in  the  second  quarter  of  2012.  We  believe  we  are 
owed dayrate by either or both of these clients. The operating dayrate was approximately $538,000 per day for the work in Libya. The 
arbitration process is proceeding, and we intend to vigorously pursue these claims. As a result of the uncertainties noted above, we

have not recognized any revenue during the assignment period and the matter could have a material positive effect on our results of 
operations or cash flows in the period the matter is resolved should the arbitration panel ultimately rule in our favor.  

In August 2007, we entered into a drilling contract with Marathon Oil Company (“Marathon”) for the Noble Jim Day to 
operate in the U.S. Gulf of Mexico. On January 1, 2011, Marathon provided notice that it was terminating the contract. Marathon’s 
stated  reason  for  the  termination  was  that  the  rig  had  not  been  accepted  by  Marathon  by  December 31,  2010,  and  Marathon  also 
maintained  that  a  force  majeure  condition  existed  under  the  contract.  The  contract  contained  a  provision  allowing  Marathon  to 
terminate if the rig had not commenced operations by December 31, 2010. We believe the rig was ready to commence operations and 
should have been accepted by Marathon. The contract term was for four years. No revenue has been recognized under this contract. 
We have contracted the rig for much of the original term with other customers. In March 2011, we filed suit in Texas State District 
Court against Marathon seeking damages for its actions. The suit is proceeding and we expect the trial to occur in the third quarter of 
2013. We cannot provide assurance as to the outcome of this lawsuit.  

In November 2012, the U.S. Coast Guard in Alaska conducted an inspection of our drillship, the Noble Discoverer, and 
cited a number of deficiencies that needed to be remediated, including issues relating to the main propulsion and safety management 
system.  We  initiated  a  comprehensive  effort  to  address  the  deficiencies  identified  by  the  Coast  Guard  and  commenced  an  ongoing 
dialogue with the agency to keep it apprised of our progress. We began an internal investigation in conjunction with the Coast Guard 
inspection, and the Coast Guard then began their own investigation. We reported certain potential violations of applicable law to the 
Coast Guard identified as a result of our internal investigation. These related to what we believe were certain unauthorized disposals 
of collected deck and sea water from the Noble Discoverer, as well as potential record-keeping issues with the oil record books for the 
Noble Discoverer and other rigs. The Coast Guard has referred the Noble Discoverer matter to the U.S. Department of Justice (“DOJ”) 
for further investigation. We are cooperating with the DOJ and Coast Guard in connection with their investigation. We cannot predict 
when the DOJ and Coast Guard will conclude the investigation and cannot provide any assurances with respect to the outcome. If the 
DOJ  or  Coast  Guard  determines  that  violations  of  applicable  law  have  occurred,  they  could  seek  civil  and  criminal  sanctions, 
including monetary penalties, against us and/or certain of our employees, as well as oversight of our operational compliance programs. 
Based on information obtained to date, we believe it is probable that we will have to pay an amount to resolve this matter. However, 
we are not in a position to estimate the potential liability that may result and have not made any accrual in our consolidated financial 
statements at December 31, 2012.  

In  January  2012,  we  were  assessed  a  fine  by  the  Brazilian  government  in  the  amount  of  R$1.8  million  (approximately 
$878,000) in connection with the inadvertent discharge of drilling fluid from one of our rigs offshore Brazil in September 2011. We 
have accepted and paid the assessment.  

In  October  2011,  we  were  assessed  a  fine  by  the  Brazilian  government  in  the  amount  of  R$238,000  (approximately 
$116,000) in connection with the inadvertent discharge of approximately 200 barrels of drilling fluid from one of our vessels offshore 
Brazil in November 2010. We plan on appealing this judgment to the full extent permissible by law.  

We are from time to time a party to various lawsuits that are incidental to our operations in which the claimants seek an 
unspecified amount of  monetary damages for personal injury, including injuries purportedly resulting from exposure to asbestos on 
drilling rigs and associated facilities. At December 31, 2012, there were approximately 29 of these lawsuits in which we are one of 
many defendants. These lawsuits have been filed in the United States in the states of Louisiana, Mississippi and Texas. We intend to 
defend vigorously against the litigation. We do not believe the ultimate resolution of these matters will have a material adverse effect 
on our financial position, results of operations or cash flows.  

We are a defendant in certain claims and litigation arising out of operations in the ordinary course of business, including 
certain disputes with customers over receivables discussed in Note 5, the resolution of which, in the opinion of management, will not 
be  material  to  our  financial  position,  results  of  operations  or  cash  flows.  There  is  inherent  risk  in  any  litigation  or  dispute  and  no 
assurance can be given as to the outcome of these claims.  

We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to 
review and examination by tax authorities within those jurisdictions. The IRS has completed its examination of our tax reporting for 
the taxable year ended December 31, 2008. The examination team has proposed adjustments with respect to certain items that  were 
reported by us for the 2008 tax year. We believe that we have accurately reported all amounts included in our 2008 tax returns, and 
have filed protests with the IRS Appeals Office contesting the examination team’s proposed adjustments, and we are still waiting on a 
final resolution of these issues. We intend to vigorously defend our reported positions. The IRS has begun its examination of our tax 
reporting  for  the  taxable  year  ended  December 31,  2009. We  believe  that  we  have  accurately  reported  all  amounts  in  our  2009  tax 
returns.  During  the  third  quarter  of  2012,  a  U.S.  subsidiary  of  Frontier  concluded  its  audit  with  the  IRS  for  its  2007  and  2008  tax

returns, resulting in no change to income tax expense. Furthermore, we are currently contesting several non-U.S. tax assessments and 
may contest future assessments when we disagree with those assessments based on the technical merits of the positions established at 
the time of the filing of the tax return. We believe the ultimate resolution of the outstanding assessments, for which we have not made 
any accrual, will not have a material adverse effect on our consolidated financial statements. We recognize uncertain tax positions that 
we  believe  have  a  greater  than  50 percent  likelihood  of  being  sustained.  We  cannot  predict  or  provide  assurance  as  to  the  ultimate 
outcome of the existing or future assessments.  

Our  Mexican  income  tax  returns  have  been  examined  for  the  2002  through  2007  periods  and  audit  claims  have  been 
assessed for approximately $321 million (including interest and penalties). During 2011, we received from the Regional Chamber of 
the Federal Tax Court adverse decisions with respect to approximately $6 million in assessments related to depreciation deductions, 
which  we are appealing. We  are also contesting all other assessments in Mexico. Tax authorities in Mexico and other jurisdictions 
may issue additional assessments or pursue legal actions as a result of tax audits and we cannot predict or provide assurance as to the 
ultimate outcome of such assessments and legal actions.  

Additional audit claims of approximately $123 million attributable to income, customs and other business taxes have been 
assessed against us in other jurisdictions. We have contested, or intend to contest, these assessments, including through litigation if 
necessary, and we believe the ultimate resolution, for which we have not made any accrual, will not have a material adverse effect on 
our consolidated financial statements.  

We maintain certain insurance coverage against specified marine perils, which includes physical damage and loss of hire. 
Damage  caused  by  hurricanes  has  negatively  impacted  the  energy  insurance  market,  resulting  in  more  restrictive  and  expensive 
coverage for U.S. named windstorm perils. Accordingly, we have elected to significantly reduce the named windstorm insurance on 
our rigs operating in the U.S. Gulf of Mexico. Presently, we insure the Noble Jim Thompson, Noble Amos Runner and Noble Driller 
for “total loss only” when caused by a named windstorm. Our customer assumes the risk of loss on the Noble Bully I due to a named 
windstorm event up to $450 million per occurrence pursuant to the terms of the drilling contract relating to such vessel, provided that 
we are responsible for the first $25 million per occurrence for such named windstorm events. The remaining rigs in the U.S. Gulf of 
Mexico are self-insured for named windstorm perils. Our rigs located in the Mexico portion of the Gulf of Mexico remain covered by 
commercial  insurance  for  windstorm  damage.  In  addition,  we  maintain  physical  damage  deductibles  on  our  rigs  ranging  from  $15 
million  to  $25  million  per  occurrence,  depending  on  location. The  loss  of  hire  coverage  applies  only  to  our  rigs  operating  under 
contract  with  a  dayrate  equal  to  or  greater  than  $200,000  a  day  and  is  subject  to  a  45-day  waiting  period  for  each  unit  and  each 
occurrence.  

Although  we  maintain  insurance  in  the  geographic  areas  in  which  we  operate,  pollution,  reservoir  damage  and 
environmental risks generally are not fully insurable. Our insurance policies and contractual rights to indemnity may not adequately 
cover our losses or may have exclusions of coverage for some losses. We do not have insurance coverage or rights to indemnity for all 
risks, including loss of hire insurance on most of the rigs in our fleet. Uninsured exposures may include expatriate activities prohibited 
by U.S. laws and regulations, radiation hazards, certain loss or damage to property on board our rigs and losses relating to shore-based 
terrorist acts or strikes. If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it 
could materially adversely affect our financial position, results of operations or cash flows. Additionally, there can be no assurance 
that  those  parties  with  contractual  obligations  to  indemnify  us  will  necessarily  be  financially  able  to  indemnify  us  against  all  these 
risks.  

We  carry  protection  and  indemnity  insurance  covering  marine  third  party  liability  exposures,  which  also  includes 
coverage for employer’s liability resulting  from personal injury to our offshore drilling  crews. Our protection and indemnity policy 
currently has a standard deductible of $10 million per occurrence, with maximum liability coverage of $750 million.  

In connection with our capital expenditure program, we had outstanding commitments, including shipyard and purchase 

commitments of approximately $2.8 billion at December 31, 2012.  

We  have  entered  into  agreements  with  certain  of  our  executive  officers,  as  well  as  certain  other  employees.  These 
agreements  become  effective  upon  a  change  of  control  of  Noble-Swiss  (within  the  meaning  set  forth  in  the  agreements)  or  a 
termination of employment in connection with or in anticipation of a change of control, and remain effective for three years thereafter. 
These agreements provide for compensation and certain other benefits under such circumstances.  

Nigerian Operations  

During the fourth quarter of 2007, our Nigerian subsidiary received letters from the Nigerian Maritime Administration and 
Safety  Agency (“NIMASA”)  seeking to collect a 2 percent surcharge on contract amounts under contracts performed  by  “vessels,” 

81 

NOBLE CORPORATION (NOBLE-SWISS) AND SUBSIDIARIES 
NOBLE CORPORATION (NOBLE-CAYMAN) AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

within the meaning of Nigeria’s cabotage laws, engaged in the Nigerian coastal shipping trade. Although we do not believe that these 
laws apply to our ownership of drilling units, NIMASA is seeking to apply a provision of the Nigerian cabotage laws (which became 
effective on May 1, 2004) to our offshore drilling units by considering these units to be “vessels” within the meaning of those laws 
and  therefore  subject  to  the  surcharge,  which  is  imposed  only  upon  “vessels.”  Our  offshore  drilling  units  are  not  engaged  in  the 
Nigerian coastal shipping trade and are not in our view “vessels” within the meaning of Nigeria’s cabotage laws. In January 2008, we 
filed  an  originating  summons  against  NIMASA  and  the  Minister  of  Transportation  in  the  Federal  High  Court  of  Lagos,  Nigeria 
seeking,  among  other  things,  a  declaration  that  our  drilling  operations  do  not  constitute  “coastal  trade”  or  “cabotage”  within  the 
meaning  of  Nigeria’s  cabotage  laws  and  that  our  offshore  drilling  units  are  not  “vessels”  within  the  meaning  of  those  laws.  In 
February 2009, NIMASA filed suit against us in the Federal High Court of Nigeria seeking collection of the cabotage surcharge. In 
August 2009, the court issued a favorable ruling in response to our originating  summons  stating that drilling operations do not  fall 
within the cabotage laws and that drilling rigs are not vessels for purposes of those laws. The court also issued an injunction against 
the  defendants  prohibiting  their  interference  with  our  drilling  rigs  or  drilling  operations.  NIMASA  has  appealed  the  court’s  ruling, 
although  the  court  dismissed  NIMASA’s  lawsuit  filed  against  us  in  February  2009.  We  intend  to  take  all  further  appropriate  legal 
action to resist the application of Nigeria’s cabotage laws to our drilling units. The outcome of any such legal action and the extent to 
which  we  may  ultimately  be  responsible  for  the  surcharge  is  uncertain.  If  it  is  ultimately  determined  that  offshore  drilling  units 
constitute vessels within the meaning of the Nigerian cabotage laws, we may be required to pay the surcharge and comply with other 
aspects  of  the  Nigerian  cabotage  laws,  which  could  adversely  affect  our  operations  in  Nigerian  waters  and  require  us  to  incur 
additional costs of compliance.  

NIMASA had previously informed the Nigerian Content Division of its position that we were not in compliance with the 
cabotage  laws.  The  Nigerian  Content  Division  makes  determinations  of  companies’  compliance  with  applicable  local  content 
regulations  for  purposes  of  government  contracting,  including  contracting  for  services  in  connection  with  oil  and  gas  concessions 
where the Nigerian national oil company is a partner. The Nigerian Content Division had previously barred us from participating in 
new  tenders  as  a  result  of  NIMASA’s  allegations,  although  the  Division  reversed  its  actions  based  on  the  favorable  Federal  High 
Court ruling. However, no assurance can be given with respect to our ability to bid for future work in Nigeria until our dispute with 
NIMASA is resolved.  

In  2007,  we  began,  and  voluntarily  contacted  the  U.S.  Securities  and  Exchange  Commission  (“SEC”)  and  the  DOJ  to 
advise them of an internal investigation of the legality under the United States Foreign Corrupt Practices Act (“FCPA”) and local laws 
of certain reimbursement payments made by our Nigerian affiliate to our customs agents in Nigeria. In 2010, we finalized settlements 
of this matter with each of the SEC and the DOJ. Pursuant to these settlements, we agreed to pay fines and penalties to the DOJ and 
the SEC and to certain undertakings, including refraining from violating the FCPA and other anti-corruption laws, self-reporting any 
violations  of  the  FCPA  or  such  laws  to  the  DOJ  and  reporting  to  the  DOJ  on  an  annual  basis  our  progress  on  anti-corruption 
compliance matters. Our ability to comply with the terms of the settlements is dependent on the success of our ongoing compliance 
program, including our ability to continue to manage our agents and supervise, train and retain competent employees, and the efforts 
of our employees to comply with applicable law and our code of business conduct and ethics.  

In  January  2011,  the  Nigerian  Economic  and  Financial  Crimes  Commission  and  the  Nigerian  Attorney  General  Office 
initiated an investigation into these same activities. A subsidiary of Noble-Swiss resolved this matter through the execution of a non-
prosecution agreement dated January 28, 2011. Pursuant to this agreement, the subsidiary paid $2.5 million to resolve all charges and 
claims of the Nigerian government.  

Any  additional  investigation  by  these  or  other  agencies  could  damage  our  reputation  and  result  in  substantial  fines, 
sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, 
results  of  operations  or  financial  condition.  Further,  resolving  any  additional  investigations  could  be  expensive  and  consume 
significant time and attention of our senior management.  

Under the Nigerian Industrial Training Fund Act of 2004, as amended, (the “Act”), Nigerian companies with five or more 
employees must contribute annually 1 percent of their payroll to the Industrial Training Fund (“ITF”) established under the Act to be 
used for the training of Nigerian nationals with a view towards generating a pool of indigenously trained manpower. We have not paid 
this  amount  on  our  expatriate  workers  employed  by  our  non-Nigerian  employment  entity  in  the  past  as  we  did  not  believe  the 
contribution obligation was applicable to them. In October 2012, we received a demand from the ITF for payments going back to 2004 
and associated penalties in respect of these expatriate employees. We do not believe that we owe the amount claimed and that, in the 
event we were to have any liability, it would not have a material adverse effect on our financial position or cash flows. We continue to 
investigate the matter and have also had discussions with the ITF to resolve the issue.

Note 17- Segment and Related Information  

We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how 
we manage our business, and the fact that all of our drilling fleet is dependent upon the worldwide oil industry. The mobile offshore 
drilling units comprising our offshore rig fleet operate in a single, global market for contract drilling services and are often redeployed 
globally due to changing demands of our customers,  which consist largely of major non-U.S. and government owned/controlled oil 
and gas companies throughout the world. Our contract drilling services segment conducts contract drilling operations in U.S. Gulf of 
Mexico and Alaska, Mexico, Brazil, the North Sea, the Mediterranean, West Africa, the Middle East, India, Australia and the Asian 
Pacific.  

The  accounting  policies  of  our  reportable  segment  are  the  same  as  those  described  in  the  summary  of  significant 
accounting policies (see Note 1). We evaluate the performance of our operating segment based on revenues from external customers 
and segment profit. Summarized financial information of our reportable segment for the years ended December 31, 2012, 2011 and 
2010 is shown in the following table. The “Other” column includes results of labor contract drilling services in Canada and Alaska, as 
well  as  corporate  related  items.  The  consolidated  financial  statements  of  Noble-Swiss  include  the  accounts  of  Noble-Cayman,  and 
Noble-Swiss  conducts  substantially  all  of  its  business  through  Noble-Cayman  and  its  subsidiaries.  As  a  result,  the  summarized 
financial information for Noble-Cayman is substantially the same as Noble-Swiss.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data) 

Note 20- Other Financial Information  

The following are Swiss statutory disclosure requirements:  

(i) Expenses  

Total  personnel  expenses  amounted  to  $699  million,  $746  million  and  $649  million  for  the  years  ended  December 31, 

2012, 2011 and 2010, respectively.  

(ii) Fire Insurance  

Total fire insurance values of property and equipment amounted to $13.1 billion and $12.2 billion at December 31, 2012 

and 2011, respectively.  

(iii) Risk assessment and Management  

The Board of Directors, together with the management of Noble, is responsible for assessing risks related to the financial 
reporting  process  and  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Internal  control  over 
financial reporting is a process designed by, or under the supervision of the Chief Executive Officer and Chief Financial Officer to 
provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  Noble’s  consolidated  financial 
statements for external purposes in accordance with GAAP.  

The Board, operating through its Audit Committee composed entirely of directors who are not officers or employees of 
the  Company,  is  responsible  for  oversight  of  the  financial  reporting  process  and  safeguarding  of  assets  against  unauthorized 
acquisition, use, or disposition. The Audit Committee meets with management, the independent registered public accountants and the 
internal  auditor;  approves  the  overall  scope  of  audit  work  and  related  fee  arrangements;  and  reviews  audit  reports  and  findings.  In 
addition, the  independent registered public accountants and the  internal auditor  meet separately  with  the  Audit Committee,  without 
management representatives present, to discuss the results of their audits; the adequacy of the Company’s internal control; the quality 
of its financial reporting; and the safeguarding of assets against unauthorized acquisition, use, or disposition.

Evaluation of Disclosure Controls and Procedures  

David W. Williams, Chairman, President and Chief Executive Officer of Noble Corporation, a Swiss corporation (“Noble-
Swiss”), and James A. MacLennan, Senior Vice President and Chief Financial Officer of Noble-Swiss, have evaluated the disclosure 
controls  and  procedures  of  Noble-Swiss  as  of  the  end  of  the  period  covered  by  this  report.  On  the  basis  of  this  evaluation, 
Mr. Williams  and  Mr. MacLennan  have  concluded  that  Noble-Swiss’  disclosure  controls  and  procedures  were  effective  as  of 
December 31, 2012. Noble-Swiss’ disclosure controls and procedures are designed to ensure that information required to be disclosed 
by Noble-Swiss in the reports that it files with or submits to the SEC are recorded, processed, summarized and reported within the 
time periods specified in  the  SEC’s rules and forms and is accumulated and communicated to  management as appropriate to allow 
timely decisions regarding required disclosure.  

David W. Williams, President and Chief Executive Officer of Noble Corporation, a Cayman Islands company (“Noble-
Cayman”),  and  Dennis  J.  Lubojacky,  Vice  President  and  Chief  Financial  Officer  of  Noble-Cayman,  have  evaluated  the  disclosure 
controls  and  procedures  of  Noble-Cayman  as  of  the  end  of  the  period  covered  by  this  report.  On  the  basis  of  this  evaluation, 
Mr. Williams  and  Mr. Lubojacky  have  concluded  that  Noble-Cayman’s  disclosure  controls  and  procedures  were  effective  as  of 
December 31,  2012.  Noble-Cayman’s  disclosure  controls  and  procedures  are  designed  to  ensure  that  information  required  to  be 
disclosed by Noble-Cayman in the reports that it files with or submits to the SEC are recorded, processed, summarized and reported 
within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to management as appropriate to 
allow timely decisions regarding required disclosure.  

Changes in Internal Control over Financial Reporting  

There  was  no  change  in  either  Noble-Swiss’  or  Noble-Cayman’s  internal  control  over  financial  reporting  that  occurred 
during  the  quarter  ended  December 31,  2012  that  has  materially  affected,  or  is  reasonably  likely  to  materially  affect,  the  internal 
control over financial reporting of each of Noble-Swiss or Noble-Cayman.  

Management’s Annual Report on Internal Control Over Financial Reporting  

The  management  of  Noble-Swiss  and  Noble-Cayman  is  responsible  for  establishing  and  maintaining  adequate  internal 
control  over  financial  reporting,  as  such  term  is  defined  in  Rule 13a-15(f)  promulgated  under  the  U.S.  Securities  Exchange  Act  of 
1934, as amended.  

Internal  control  over  financial  reporting  includes  the  controls  themselves,  monitoring  (including  internal  auditing 
practices), and actions taken to correct deficiencies as identified. There are inherent limitations to the effectiveness of internal control 
over financial reporting, however well designed, including the possibility of human error and the possible circumvention or overriding 
of  controls.  The  design  of  an  internal  control  system  is  also  based  in  part  upon  assumptions  and  judgments  made  by  management 
about the likelihood of future events, and there can be no assurance that an internal control will be effective under all potential future 
conditions. As a result, even an effective system of internal controls can provide no more than reasonable assurance with respect to the 
fair presentation of financial statements and the processes under which they were prepared.  

Under  the  supervision  and  with  the  participation  of  our  management,  including  our  Chief  Executive  Officer  and  Chief 
Financial  Officer,  we  conducted  an  evaluation  of  the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the 
framework  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission.  Based  on  the  management  of  Noble-Swiss  and  Noble-Cayman  assessment,  both  Noble-Swiss  and  Noble-Cayman 
maintained effective internal control over financial reporting as of December 31, 2012.  

PricewaterhouseCoopers  LLP,  the  independent  registered  public  accounting  firm  that  audited  our  financial  statements 
included  in  this  Annual  Report  on  Form  10-K,  has  audited  the  effectiveness  of  internal  control  over  financial  reporting  as  of 
December 31, 2012 as stated in their report, which is provided in this Annual Report on Form 10-K.

Report of the statutory auditor 
to the general meeting of 
Noble Corporation 
Baar 

Report of the statutory auditor on the financial statements 

As statutory auditor, we have audited the accompanying financial statements of Noble Corporation, which 
comprise the balance sheet, statement of income and notes (pages S2 to S16), for the year ended December 
31, 2012. 

Board of Directors’ Responsibility 

The Board of Directors is responsible for the preparation of the financial statements in accordance with 
the requirements of Swiss law and the company’s articles of incorporation. This responsibility includes 
designing, implementing and maintaining an internal control system relevant to the preparation of finan-
cial statements that are free from material misstatement, whether due to fraud or error. The Board of 
Directors is further responsible for selecting and applying appropriate accounting policies and making 
accounting estimates that are reasonable in the circumstances.  

Auditor’s Responsibility 

Our responsibility is to express an opinion on these financial statements based on our audit. We conducted 
our audit in accordance with Swiss law and Swiss Auditing Standards. Those standards require that we 
plan and perform the audit to obtain reasonable assurance whether the financial statements are free from 
material misstatement.  

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in 
the financial statements. The procedures selected depend on the auditor’s judgment, including the as-
sessment of the risks of material misstatement of the financial statements, whether due to fraud or error. 
In making those risk assessments, the auditor considers the internal control system relevant to the entity’s 
preparation of the financial statements in order to design audit procedures that are appropriate in the 
circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal 
control system. An audit also includes evaluating the appropriateness of the accounting policies used and 
the reasonableness of accounting estimates made, as well as evaluating the overall presentation of the 
financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to 
provide a basis for our audit opinion. 

Opinion 

In our opinion, the financial statements for the year ended December 31, 2012 comply with Swiss law and 
the company’s articles of incorporation.

patible with our independence. 

In accordance with article 728a paragraph 1 item 3 CO and Swiss Auditing Standard 890, we confirm that 
an internal control system exists which has been designed for the preparation of financial statements 
according to the instructions of the Board of Directors. 

We further confirm that the proposed appropriation of legal reserves from capital contribution complies 
with Swiss Law and the Company's articles of association. We recommend that the financial statements 
submitted to you be approved.

1. Basis of presentation 

Noble Corporation, a Swiss  Corporation (“Noble”,  “Noble-Swiss”, the  “Company”,  “we”, “our” 
and  words of similar import), is a  holding company listed  on the New  York Stock Exchange (“NYSE”), 
engaged in the management of companies which provide offshore drilling contract services for the oil and 
gas industry.     

On  March  26,  2009,  pursuant  to  the  previously  announced  Agreement  and  Plan  of  Merger, 
Reorganization and Consolidation, dated as of December 19, 2008 (as amended, the “Merger Agreement”), 
among  Noble-Swiss,  Noble  Corporation,  a  Cayman  Island  Company,  (“Noble-Cayman”),  and  Noble 
Cayman  Acquisition  Ltd.,  a  Cayman  Islands  company  and  a  wholly-owned  subsidiary  of  Noble-Swiss 
(“Noble-Acquisition”), Noble-Cayman merged by way of schemes of arrangement under Cayman Islands 
law  (the  “Schemes  of  Arrangement”)  with  Noble-Acquisition,  with  Noble-Cayman  as  the  surviving 
company  (the  “Transaction”).  Under  the  terms  of  the  Schemes  of  Arrangement,  each  holder  of  Noble-
Cayman ordinary  shares outstanding immediately prior to the Transaction received, through an exchange 
agent, one Noble-Swiss registered share in exchange for each outstanding Noble-Cayman ordinary share, 
and  Noble-Cayman  received,  through  an  exchange  agent,  a  number  of  newly  issued  Noble-Cayman 
ordinary shares equal to the number of Noble-Cayman ordinary shares outstanding immediately prior to the 
Transaction.  Shares of Noble-Swiss trade on the NYSE under the symbol “NE”.  This transaction became 
effective under Swiss law on March 27, 2009. 

The  financial  statements  present  the  financial  position  of  the  holding  company  on  a  standalone 
basis and do not represent the consolidated financial position of the holding company and its subsidiaries. 
The accounts are prepared in accordance with Swiss Law (Swiss Code of Obligations).  All amounts in the 
notes are shown in thousands of Swiss Francs, unless otherwise stated. 

2. Significant accounting policies 

a) Cash and cash equivalents 

Cash and cash equivalents includes cash on hand and deposits with an original maturity of three 

months or less at time of purchase. 

b) Treasury shares  

Treasury shares are classified as long-term assets on the balance sheet and are valued at the cost of 
the shares  which are purchased.  This classification in the balance sheet is consistent  with management’s 
intent to hold the shares for a period outside of one year.  

c) Investments in subsidiaries 

Investments  in  subsidiaries  are  equity  interests,  which  are  held  on  a  long-term  basis  for  the 
purpose of the holding company’s business activities. They are carried at a value no higher than their cost, 
determined  via  reference  to  fair  market  value  or  amounts  paid  for  the  investment,  less  adjustments  for 
impairment, if any. The cost  of the  Company's primary  investment in Noble-Cayman  was determined by 
reference to fair market value of the contributed share capital of Noble-Cayman, on the basis of the closing 
price of the ordinary shares of Noble-Cayman as reported on the NYSE on the date of transaction, plus a 
premium, which was determined via a discounted cash flow analysis. 

At December 31, 2012, the fair market value of the investment in Noble-Cayman was determined 
to  be  below  the  historical  cost  basis  of  the  investment.  Accordingly,  a  valuation  allowance  of  CHF  1.3 
billion  consisting  primarily  of  the  impact  of  the  decline  in  the  U.S.  dollar  against  the  Swiss  franc  was 
recorded in the 2012 statement of income to reduce the cost basis of the investment in Noble-Cayman to 
fair market value. The investment value and the associated valuation allowance have been recorded on the 
balance sheet.

d) Translation of foreign currencies 

Assets, other than investments in subsidiaries, and liabilities denominated in foreign currencies are 
converted  at  year  end  exchange  rates.  Revenues  and  expenses  denominated  in  foreign  currencies  are 
converted  using  an  average  exchange  rate.  Unrealized  exchange  losses  are  recorded  in  the  statement  of 
income and unrealized exchange gains are deferred until realized. 

e) Dividends 

Our  shareholders  approve  the  payment  of  dividends  at  the  annual  shareholder  meeting,  which  are 
funded from capital contribution. Subject to shareholder approval, a dividend reserve is established, from 
which  the  expected  liability  to  shareholders  is  funded.  Amounts  are  translated  to  CHF  prior  to  the 
respective  payment  dates  (in  each  case  subject  to  the  availability  of  a  sufficient  amount  in  the  dividend 
reserve), and the dividend reserve is adjusted for exchange rate differences at the respective payment dates. 
Any amount of the dividend reserve remaining after the payment of the final quarterly  installment of the 
dividend will be reallocated to the capital contribution reserve.

As of December 31, 2012, the board of directors is authorized to issue new registered shares at any

each  subsequent  two-year  period,  authorized  share  capital  will  be  available  to  the  board  of  directors  for 
issuance  of  additional  registered  shares  only  if  the  authorization  is  reapproved  by  shareholders.  The 
Company’s  Board  of  Directors  will  recommend  to  the  annual  general  meeting  of  shareholders  that  this 
authority be extended for two years until April 25, 2015.  

The amounts as of December 31, 2012 above include a return in capital of CHF 0.26 in the form of 
a par value reduction and $0.26 in the form of a dividend funded from our dividend reserve. The amounts

with the Swiss Commercial Registry in July 2011.  

d) Share repurchase authorization 

In March 2009, the Board of Directors (the Board) authorized the plan of the predecessor company 
to repurchase common shares, up to an aggregate total of 50,000,000 shares. At March 27, 2009, a total of 
16,619,891 shares remained available under this authorization.  These purchases may take place from time 
to time in the open market or in private purchase transactions. From March 27, 2009 through December 31,

reduction. In August 2012 and November 2012, we made dividend payments, including dividend payments 
on  shares  held  by  one  of  our  subsidiaries,  in  the  amount  of  CHF  33,759,949  and  CHF  32,565,791, 
respectively, out of capital contribution.  

5. Contingent liability  

The  company  is  a  member  of  a  VAT  group  and  is  therefore  jointly  and  severally  liable  for  the 

payment of the VAT liabilities of the other members of the Swiss VAT group. 

6. Remuneration of the Board of Directors and the Group Executives  

a) Basis of presentation 

The following information sets forth the compensation for the years ended December 31, 2012 and 
2011 for the members of the Board of Directors of Noble and Group Executives for all of the functions that 
they have performed for the Company.  Compensation is presented for the years ended December 31, 2012 
and  2011.  Compensation  of  the  Board  is  paid  by  Noble  or  one  of  its  subsidiaries.  Compensation  of  the 
Group Executives is paid by Noble and the group entities where they are employed.  Compensation is paid 
as  a  combination  of  both  U.S.  dollars  and  Swiss  francs,  though  the  following  tables  express  all 
remuneration details in whole Swiss francs with totals in both Swiss francs and U.S. dollars.  

b) Remuneration of the Board of Directors 

The compensation committee of our Board sets the compensation of our directors. In determining 
the  appropriate  level  of  compensation  for  our  directors,  the  compensation  committee  considers  the 
commitment required from our directors in performing their duties on behalf of the Company, as well as 
comparative  information  the  committee  obtains  from  compensation  consulting  firms  and  from  other 
sources.  During  the  years  ended  December  31,  2012  and  2011,  no  directors  received  benefits  in  kind  or 
waivers of claims and no compensation was paid to any related party of current or former directors nor did 
any related parties of current or former directors receive any benefits in kind or waivers of claim.  As of 
December  31,  2012  and  2011,  no  current  or  former  directors  or  any  related  party  of  current  or  former 
directors had any outstanding loans or credits from the Company.  Set forth below is a description of the 
compensation of our directors.  

i) Annual Retainers and Other Fees and Expenses.  

We pay our non-employee directors an annual retainer of $50,000 (CHF 46,735 in 2012 and CHF 
43,923 in 2011) of which 20 percent is paid in shares under the Noble Corporation Equity Compensation 
Plan for Non-Employee Directors. Under this plan, non-employee directors may elect to receive up to all of 
the  remaining  80  percent  in  shares  or  cash.  Non-employee  directors  make  elections  on  a  quarterly  basis. 
The number of shares to be issued under the plan in any particular quarter is generally determined using the 
average  of  the  daily  closing  prices  of  the  shares  for  the  last  15  consecutive  trading  days  of  the  previous 
quarter.  No  options  are  issuable  under  the  plan,  and  there  is  no  “exercise  price”  applicable  to  shares 
delivered under the plan.  

In  addition,  we  pay  our  non-employee  directors  a  Board  meeting  fee  of  $2,000  (CHF  1,869  in 
2012  and  CHF  1,757  in  2011).  We pay  each  member  of  our  audit  committee  a  committee  fee  of  $2,500 
(CHF  2,337  in  2012  and  CHF  2,196  in  2011)  per  meeting  and  each  member  of  our  other  committees  a 
committee meeting fee of $2,000 (CHF 1,869 in 2012 and CHF 1,757 in 2011) per meeting.  

In  2011,  the  chair  of  the  audit  committee,  as  well  as  the  chair  of  the  nominating  and  corporate 
governance  committee,  each  received  an  annual  retainer  of  $15,000  (CHF  13,177)  and  the  chair  of  the 
compensation committee received an annual retainer of $12,500 (CHF 10,981).  

In 2012, the chair of the audit committee received an annual retainer of $25,000 (CHF 23,368), the

the  nominating  and  corporate  governance  committee,  as  well  as  the  chair  of  each  other  standing  Board 
committee, each received an annual retainer of $15,000 (CHF 14,021). The lead director also received an 
annual fee of $20,000 (CHF 18,694).  

We also reimburse directors for travel, lodging and related expenses they may incur in attending 

Board and committee meetings. 

ii) Non-Employee Director Stock Options and Restricted Shares.  

Under the 1992 Plan, each annually-determined award of a variable number of Restricted Shares 
or unrestricted shares is made on a date selected by the Board, or if no such date is selected by the Board, 
the date on which the Board action approving such award is taken. Any future award of Restricted Shares 
will be evidenced by a written agreement that will include such terms and conditions not inconsistent with 
the terms and conditions of the 1992 Plan as the Board considers appropriate in each case.  

On  July 29,  2011,  an  award  of  7,888  unrestricted  shares  under  the  1992 Plan  was  made  to  each 
non-employee  director  serving  on  that  date.  Based  on  a  review  of  market  data  provided  by  the 
compensation  consultant,  the  market  value  of  this  award  approximated  the  75th  percentile  of  the 
compensation  paid  to  non-employee  directors  in  the  comparator  groups.  The  value  of  the  63,104 
unrestricted  share  award  was  $2.3  million  (CHF  2.0  million)  which  was  immediately  recognized  by  the 
Company at the time of the award. 

On  July 27,  2012,  an  award  of  8,332  unrestricted  shares  under  the  1992 Plan  was  made  to  each 
non-employee  director  serving  on  that  date.  Based  on  a  review  of  market  data  provided  by  the 
compensation  consultant,  the  market  value  of  this  award  approximated  the  75th  percentile  of  the 
compensation  paid  to  non-employee  directors  in  the  comparator  groups.  The  value  of  the  58,324 
unrestricted  share  award  was  $2.2  million  (CHF  2.1  million)  which  was  immediately  recognized  by  the 
Company at the time of the award. 

The  following  table  shows  the  compensation  of  our  directors  for  the  years  ended  December 31, 
2012  and  2011.  Although  David  W.  Williams  is  Chairman  of  the  Board,  details  of  Mr.  Williams' 
compensation are included in Section C.

c) Remuneration of Group Executives 

The compensation committee of our Board is responsible for determining the compensation of our 
directors  and  executive  officers  and  for  establishing,  implementing  and  monitoring  adherence  to  our 
executive  compensation  philosophy.  The  compensation  committee  provides  guidance  to  our  Board  in 
incentive  and  equity-based 
the  compensation  programs,  benefits, 
reviewing  and  administering 
compensation  plans.  The  compensation  committee  operates  independently  of  management  and  receives 
compensation advice and data from outside advisors. 

The  Company  believes  that  its  executive  compensation  program  reflects  the  Company’s 
philosophy  that  executive  compensation  should  be  structured  so  as  to  closely  align  each  executive’s 
interests  with  the  interests  of  our  shareholders.  The  program  is  designed  to  emphasize  equity-based 
incentive  and  performance-based  pay  and,  in  order  to  promote  an  atmosphere  of  teamwork,  fairness  and 
motivation; these concepts extend beyond the named executive officers to other key employees throughout 
the  Company.  The  primary  objectives  of  the  Company’s  total  compensation  package  are  to  motivate  our 
executives  to  assist  the  Company  in  achieving  certain  operating  and  financial  performance  goals  that 
enhance shareholder value, to reward outstanding performance in achieving these goals and to establish and 
maintain  a  competitive  executive  compensation  program  that  enables  the  Company  to  attract,  retain  and 
motivate high caliber executives who will contribute to the long-term success of the Company. When used 
in  this  Remuneration  section,  the  term  “Group  Executives”  means  those  persons  listed  in  the  Summary 
Compensation Table below. 

Effective  October  2011,  Thomas  Mitchell  resigned  as  Chief  Financial  Officer,  Treasurer  and 
Controller  and  Dennis  Lubojacky  was  designated  as  principal  financial  officer  and  principal  accounting 
officer  until  a  replacement  was  appointed.  Messrs.  Mitchell  and  Lubojacky  are  included  as  Group 
Executives  in  the  2011  table  below,  as  is  Lee  Ahlstrom,  Senior  Vice  President-Strategic  Development. 
Their compensation has been included on a pro-rata basis in the 2011 table below.

The Board of Directors, together with the management of Noble, is responsible for assessing risks 
related  to  the  financial  reporting  process  and  for  establishing  and  maintaining  adequate  internal  control 
over  financial  reporting.  The  Corporate  Risk  Management  function  coordinates  and  aligns  the  risk 
management  process  and  reports  to  the  Board,  the  Audit  Committee,  and  the  Corporate  Governance 
Committee  on  a  regular  basis  on  risk  assessment  and  risk  management.  Organizational  and  process 
measures  have  been  designed  to  identify  and  mitigate  risks.  Organizationally  the  responsibility  for  risk 
assessment  and  management  is  allocated  to  the  Divisions  with  specialized  Corporate  Functions  such  as 
Financial  Reporting  &  Accounting,  Treasury,  Health  Safety  and  Environment,  and  Business  Continuity 
providing support and controlling the effectiveness of the risk management by the Divisions.   

Internal control over financial reporting is a process designed by, or under the supervision of the 
Chief  Executive  Officer  and  Chief  Financial  Officer  to  provide  reasonable  assurance  regarding  the 
reliability  of  financial  reporting  and  the  preparation  of  Noble’s  consolidated  financial  statements  for 
external purposes in accordance with GAAP. 

The  Board,  operating  through  its  Audit  Committee  composed  entirely  of  directors  who  are  not 
officers or employees of the Company, is responsible for oversight of the financial reporting process and 
safeguarding  of  assets  against  unauthorized  acquisition,  use,  or  disposition.  The  Audit  Committee  meets 
with  management,  the  independent  registered  public  accountants  and  the  internal  auditor;  approves  the 
overall  scope  of  audit  work  and  related  fee  arrangements;  and  reviews  audit  reports  and  findings.  In 
addition,  the  independent  registered  public  accountants  and  the  internal  auditor  meet  separately  with  the 
Audit  Committee,  without  management  representatives  present,  to  discuss  the  results  of  their  audits;  the 
adequacy of the Company’s internal control; the quality of its financial reporting; and the safeguarding of 
assets against unauthorized acquisition, use, or disposition.

Company’s capital contribution reserve to a dividend reserve, (the “Dividend Reserve”), (B) a dividend in 
the  amount  of  USD  $1.00  per  share  to  be  distributed  out  of  the  Dividend  Reserve  and  paid  in  four 
installments of USD $0.25  per share (each, an “Installment”) in August 2013, November 2013, February 
2014 and May 2014 with amounts to be translated to CHF prior to the respective payment dates (in each 
case subject to the availability of a sufficient amount in the Dividend Reserve) provided that the Board of 
Directors shall have the authority to accelerate the payment of any Installment or portions thereof in its sole 
discretion at any time prior to payment of the final Installment and (C) the automatic re-allocation to the 
capital contribution reserve of any amount of the Dividend Reserve remaining after payment of the  final 
quarterly Installment of the dividend.

Report of the statutory auditor 
to the general meeting of 
Noble Corporation 
Baar 

Report of the statutory auditor on the consolidated financial statements 

As statutory auditor, we have audited the consolidated financial statements of Noble Corporation, 
which comprise the consolidated balance sheet (page 43), consolidated statement of  income (page 
44), consolidated statement of comprehensive income (page 45), consolidated statement of cash flows 
(page 46), consolidated statement of equity (page 47) and notes (pages 54 to 95, excluding Notes 19 
and 21, which solely relate to Noble Corporation, Cayman), for the year ended December 31, 2012. 

Board of Directors’ Responsibility 

The Board of Directors is responsible for the preparation and fair presentation of the consolidated 
financial statements in accordance with accounting principles generally accepted in the United States 
of America (US GAAP) and the requirements of Swiss law. This responsibility includes designing, 
implementing and maintaining an internal control system relevant to the preparation and fair presen-
tation of consolidated financial statements that are free from material misstatement, whether due to 
fraud or error. The Board of Directors is further responsible for selecting and applying appropriate 
accounting policies and making accounting estimates that are reasonable in the circumstances.  

Auditor’s Responsibility 

Our responsibility is to express an opinion on these consolidated financial statements based on our 
audit. We conducted our audit in accordance with Swiss law, Swiss Auditing Standards, and auditing 
standards generally accepted in the United States of America. Those standards require that we plan 
and perform the audit to obtain reasonable assurance whether the consolidated financial statements 
are free from material misstatement.  

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures 
in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, 
including the assessment of the risks of material misstatement of the consolidated financial state-
ments, whether due to fraud or error. In making those risk assessments, the auditor considers the 
internal control system relevant to the entity’s preparation and fair presentation of the consolidated 
financial statements in order to design audit procedures that are appropriate in the circumstances, but 
not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control system. 
An audit also includes evaluating the appropriateness of the accounting policies used and the reasona-
bleness of accounting estimates made, as well as evaluating the overall presentation of the consolidat-
ed financial statements. We believe that the audit evidence we have obtained is sufficient and appro-
priate to provide a basis for our audit opinion. 

Opinion 

In our opinion, the consolidated financial statements for the year ended December 31, 2012 present 
fairly, in all material respects, the financial position, the results of operations and the cash flows in
