ITEM 1. BUSINESS

OVERVIEW

PART I

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,”
the  “Company,”  “we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas
wells.  As of February 14, 2023, we owned or had partial ownership interests in and operated 37 mobile offshore drilling units,
consisting of 27 ultra-deepwater floaters and 10 harsh environment floaters.  Additionally, as of February 14, 2023, we were
constructing  one  ultra-deepwater  drillship  and  held  a  noncontrolling  ownership  interest  in  a  company  that  is  constructing
one ultra-deepwater drillship.

We  provide,  as  our  primary  business,  contract  drilling  services  in  a  single  operating  segment,  which  involves
contracting  our  mobile  offshore  drilling  rigs,  related  equipment  and  work  crews  to  drill  oil  and  gas  wells.   We  specialize  in
technically  demanding  regions  of  the  global  offshore  drilling  business  with  a  particular  focus  on  ultra-deepwater  and  harsh
environment  drilling  services.    Our  drilling  fleet  is  one  of  the  most  versatile  fleets  in  the  world,  consisting  of  drillships  and
semisubmersible floaters used in support of offshore drilling activities and offshore support services on a worldwide basis.

Transocean  Ltd.  is  a  Swiss  corporation  with  its  registered  office  in  Steinhausen,  Canton  of  Zug  and  with  principal
executive  offices  located  at  Turmstrasse  30,  6312  Steinhausen,  Switzerland.    Our  telephone  number  at  that  address  is
+41 41 749-0500.  Our shares are listed on the New York Stock Exchange under the ticker symbol “RIG.”  For information
about  the  revenues,  operating  income,  assets  and  other  information  related  to  our  business,  our  segments  and  the  geographic
areas in which we operate, see “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of
Operations” and “Part II. Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—
Note 1—Business, Note 4—Revenues and Note 6—Long-Lived Assets.”

DRILLING FLEET

Overview—We  provide  contract  drilling  services  using  our  fleet  of  mobile  offshore  drilling  units,  including  both
drillships and semisubmersibles, broadly referred to as floaters.  Floaters are designed to operate in locations away from port for
extended periods of time and have living quarters for the crews, a helicopter landing deck and storage space for drill pipe, riser
and  drilling  supplies.    Our  drilling  units  and  related  equipment  are  suitable  for  both  exploration  and  development,  and  we
engage in both types of activities.

Drillships are floating vessels that are shaped like conventional ships, generally self-propelled and considered to be the
most mobile of the major rig types.  Drillships typically have greater deck load and storage capacity than semisubmersible rigs,
which provides logistical and resupply efficiency benefits for customers.  Drillships are generally better suited to operations in
calmer  sea  conditions  and  typically  do  not  operate  in  areas  considered  to  be  harsh  environments.    Our  high-specification
drillships  are  equipped  with  dynamic  positioning  thruster  systems,  which  allows  them  to  maintain  position  without  anchors
through  the  use  of  onboard  propulsion  and  station-keeping  systems.    We  have  22  ultra-deepwater  drillships  that  are,  and
two  ultra-deepwater  drillships  under  construction  that  will  be,  equipped  with  our  patented  dual-activity  technology.    Dual-
activity  technology  employs  structures,  equipment  and  techniques  using  two  drilling  stations  within  a  dual  derrick  to  allow
these drillships to perform simultaneous drilling tasks in a parallel, rather than a sequential manner, which reduces critical path
activity  and  improves  efficiency  in  both  exploration  and  development  drilling.    In  addition,  our  newbuild  drillships  under
construction will be equipped with dynamic positioning thruster systems and industry-leading hoisting capacity.

Semisubmersibles are floating vessels that can be partially submerged by means of a water ballast system such that the
lower column sections and pontoons are below the water surface during drilling operations.  Semisubmersibles are known for
stability, making them well suited for operating in rough sea conditions.  Semisubmersible floaters are capable of maintaining
their position over a well either through dynamic positioning or the use of mooring systems.  Although most semisubmersible
rigs are relocated with the assistance of tugs, some units are self-propelled and move between locations under their own power
when afloat on pontoons.  Four of our 13 semisubmersibles are equipped with dual-activity technology and also have mooring
capability.  Two of these four dual-activity units are custom-designed, high-capacity semisubmersible drilling rigs, equipped for
year-round operations in harsh environments, such as those of the Norwegian continental shelf and sub-Arctic waters.

Our  floater  fleet  consists  of  ultra-deepwater  floaters  and  harsh  environment  floaters  that  are  designed  with  high-
specification  capabilities  to  operate  in  the  technically  demanding  regions  of  the  global  offshore  drilling  business.    Ultra-
deepwater  floaters  are  equipped  with  high-pressure  mud  pumps  and  are  capable  of  drilling  in  water  depths  of  4,500  feet  or
greater.    Harsh  environment  floaters  are  capable  of  drilling  in  harsh  environments  in  water  depths  between  1,500  and
10,000  feet  and  have  greater  displacement,  which  offers  larger  variable  load  capacity,  more  useable  deck  space  and  better
motion characteristics.

Fleet status—Depending on market conditions, we may idle or stack our non-contracted rigs.  An idle rig is between
drilling  contracts,  readily  available  for  operations,  and  operating  costs  are  typically  at  or  near  normal  operating  levels.    A
stacked  rig  typically  has  reduced  operating  and  maintenance  costs,  is  staffed  by  a  reduced  crew  or  has  no  crew  and  is
(a)  preparing  for  an  extended  period  of  inactivity,  (b)  expected  to  continue  to  be  inactive  for  an  extended  period,  or
(c) completing a period of extended inactivity.  Stacked rigs will continue to incur operating costs at or above normal operating
levels for approximately 30 days following initiation of stacking.  Some idle rigs and all stacked rigs require additional costs to
return to service.  The actual cost to return to service, which in many instances could be

- 2 -

Table of Contents

significant and could fluctuate over time, depends upon various factors, including the availability and cost of shipyard facilities,
the cost of equipment and materials, the extent of repairs and maintenance that may ultimately be required, the length of time a
rig  has  spent  in  stacking  mode  and  time  and  cost  of  assembling  and  training  crew.   We  consider  these  factors,  together  with
market conditions, length of contract, dayrate and other contract terms, when deciding whether to return a stacked rig to service.
 We may not return some stacked rigs to work for drilling services.

Drilling units—The  following  tables,  presented  as  of  February  9,  2023,  provide  certain  specifications  for  our  rigs.
 Unless otherwise noted, the stated location of each rig indicates either the current drilling location, if the rig is operating, or the
next operating location, if the rig is in shipyard with a follow-on contract.  The dates provided represent the expected time of
completion, the year placed into service, and, if applicable, the year of the most recent upgrade.  As of February 9, 2023, we
owned  all  of  the  drilling  rigs  in  our  fleet  noted  in  the  tables  below,  except  for  the  following:  (1)  the  ultra-deepwater  floater
Petrobras 10000, which is subject to a finance lease through August 2029, (2) the harsh environment floater Transocean Norge,
which is owned through our 33 percent noncontrolling ownership interest in Orion Holdings (Cayman) Limited (together with
its  subsidiary,  “Orion”),  and  (3)  the  newbuild  ultra-deepwater  drillship  under  construction,  to  be  named  Deepwater  Aquila,
which  is  owned  through  our  noncontrolling  ownership  interest  in  Liquila  Ventures  Ltd.  (together  with  its  subsidiaries,
“Liquila”).

DRILLING CONTRACTS

Our offshore drilling services contracts are individually negotiated and vary in their terms and conditions.  We obtain
most of our drilling contracts through bidding processes in competition against other drilling services contractors and through
direct negotiations with operators.  Drilling contracts generally provide for payment on a dayrate basis, typically with higher
rates  for  periods  when  drilling  operations  are  optimized  and  lower  or  zero  rates  for  periods  during  which  the  drilling  unit  is
mobilized or when drilling operations are interrupted, restricted by equipment breakdowns, adverse environmental conditions or
otherwise.  A dayrate drilling contract generally extends over a period of time either covering the drilling of a single well or
group  of  wells  or  covering  a  stated  term.    At  December  31,  2022,  our  contract  backlog  was  approximately  $8.34  billion,
representing an increase of 26 percent and 4 percent, respectively, compared to the contract backlog at December 31, 2021 and
2020, which was $6.60 billion and $8.06 billion, respectively.  See “Part II. Item 7. Management’s Discussion and Analysis of
Financial Condition and Results of Operations—Performance and Other Key Indicators.”

Certain of our drilling contracts may be cancelable for the convenience of the customer, typically with the payment of
an  early  termination  payment.    Such  payments,  however,  may  not  fully  compensate  us  for  the  loss  of  the  contract.    Drilling
contracts  also  customarily  provide  for  either  automatic  termination  or  termination  at  the  option  of  the  customer,  typically
without  payment  of  any  termination  fee,  under  various  circumstances  such  as  non-performance,  in  the  event  of  extended
downtime or impaired performance due to equipment or operational issues or extended downtime due to force majeure events.
 Many of these events are beyond our control.  The contract term in some instances may be extended by the customer exercising
options for the drilling of additional wells or for additional periods of time.  Our contracts also typically include a provision that
allows the customer to extend the contract to finish drilling a well-in-progress.  During periods of depressed market conditions,
our customers may seek to renegotiate drilling contracts or options to reduce the term of their obligations or the average dayrate
through term extensions or may seek to early terminate or repudiate their contracts.  Suspension of drilling contracts will result
in the reduction in or loss of dayrate for the period of the suspension.  If customers cancel some of our contracts and we are
unable to secure new contracts on a timely basis and on substantially similar or more favorable terms, if some of our contracts
are  suspended  for  an  extended  period  of  time  or  if  a  number  of  our  contracts  are  renegotiated  on  less  favorable  terms,  our
consolidated financial position, results of operations or cash flows may be adversely affected.  See “Item 1A. Risk Factors—
Risks  related  to  our  business—Our  drilling  contracts  may  be  terminated  due  to  a  number  of  events,  and,  during  depressed
market conditions, our customers may seek to repudiate or renegotiate their contracts.”

Under dayrate drilling contracts, consistent with standard industry practice, our customers, as the operators, generally
assume, and grant indemnity for, subsurface and well control risks, and their consequential damages.  Under all of our current
drilling  contracts,  our  customers  indemnify  us  for  pollution  damages  in  connection  with  reservoir  fluids  stemming  from
operations under the contract, and we indemnify our customers for pollution that originates above the surface of the water from
the  rig  from  substances  in  our  control,  such  as  diesel  used  onboard  the  rig  or  other  fluids  stored  onboard  the  rig.   Also,  our
customers indemnify us for consequential damages they incur, damage to the well or reservoir, loss of subsurface oil and gas
and the cost of bringing the well under control.  However, because our drilling contracts are individually negotiated, the degree
of indemnification we receive from our customers for the risks discussed above may vary from contract to contract based on
market conditions, customer requirements existing when the contract was negotiated or other factors.  In some instances, we
have contractually agreed upon certain limits to our indemnification rights and can be responsible for certain damages up to a
specified maximum dollar amount.  The nature of our liability and the prevailing market conditions, among other factors, can
influence such contractual terms.  Notwithstanding a contractual indemnity from a customer, there can be no assurance that our
customers will be financially able to indemnify us or will otherwise honor their contractual indemnity obligations.

The  interpretation  and  enforceability  of  a  contractual  indemnity  depends  upon  the  specific  facts  and  circumstances
involved, as governed by applicable laws, and may ultimately need to be decided by a court or other proceeding, which would
need  to  consider  the  specific  contract  language,  the  facts  and  applicable  laws.    Applicable  laws  often  consider  contractual
indemnity for criminal fines and penalties to be against public policy.  Many courts also restrict indemnification for criminal
fines  and  penalties.    The  inability  or  other  failure  of  our  customers  to  fulfill  their  indemnification  obligations,  or  the
unenforceability of all of our contractual protections could have a material adverse effect on our consolidated financial position,
results  of  operations  or  cash  flows.    See  “Item  1A.  Risk  Factors—Risks  related  to  our  business—Our  business  involves
numerous  operating  hazards,  and  our  insurance  and  indemnities  from  our  customers  may  not  be  adequate  to  cover  potential
losses from our operations.”

MARKETS

Our operations are geographically dispersed in oil and gas exploration and development areas throughout the world.
 We operate in a single, global offshore drilling market, as our drilling rigs are mobile assets and can be moved according to
prevailing market conditions.  We may mobilize our drilling rigs between regions for a variety of reasons, including to respond
to  customer  contracting  requirements  or  to  capture  observed  market  demand.    Consequently,  we  cannot  predict  the  future
percentage of our revenues that will be derived from particular geographic areas.  As of February 9, 2023, the drilling units in
our  fleet,  including  stacked  and  idle  rigs,  but  excluding  rigs  under  construction,  were  located  in  the  U.S.  Gulf  of  Mexico
(nine units), Greece (seven units), the Norwegian North Sea (six units), Brazil (five units), Malaysia (three units), the United
Kingdom (the “U.K.”) North Sea (three units), Angola (one unit), Canada (one unit), India (one unit) and Suriname (one unit).

We  categorize  the  sectors  of  the  floater  market  in  which  we  operate  as  follows:  (1)  ultra-deepwater  and  deepwater,
(2) harsh environment and (3) midwater.  We typically employ our ultra-deepwater floaters to service the ultra-deepwater and
deepwater  sector,  and  we  employ  our  harsh  environment  floaters  to  service  all  three  sectors.    We  generally  view  the  ultra-
deepwater and deepwater market sector as water depths beginning at 4,500 feet and extending to the maximum water depths in
which rigs are capable of drilling, which is currently up to 12,000 feet.  The midwater market sector includes water depths from
approximately  300  feet  to  approximately  4,500  feet.    The  harsh  environment  market  sector  includes  regions  that  are  more
challenged by lower temperatures, harsher weather conditions and water currents.

The market for offshore drilling rigs and related services reflects  our  customers’  demand  for  equipment  for  drilling
exploration, appraisal and development wells and for performing maintenance on existing production wells.  Activity levels of
energy  companies,  including  integrated  energy  companies,  independent  energy  companies  and,  to  a  lesser  extent,  national
energy companies are largely driven by the worldwide  demand  for  energy,  including  crude  oil  and  natural  gas.    Worldwide
energy  supply  and  demand  drives  oil  and  natural  gas  prices,  which,  in  turn,  impact  energy  companies’  ability  to  fund
investments in exploration, development and production activities.

See  “Part  II.  Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations—

Outlook.”

CUSTOMERS

We provide our offshore drilling services to most of the leading integrated energy companies or their affiliates, as well
as for many government-owned or government-controlled energy companies and other independent energy companies.  For the
year  ended  December  31,  2022,  our  most  significant  customers  were  Shell  plc  (together  with  its  affiliates,  “Shell”),
Equinor ASA  (together  with  its  affiliates,  “Equinor”)  and  Petróleo  Brasileiro  S.A.  (together  with  its  affiliates,  “Petrobras”),
representing  approximately  33  percent,  25  percent  and  11  percent,  respectively,  of  our  consolidated  operating  revenues.    No
other customers accounted for 10 percent or more of our consolidated operating revenues in the year ended December 31, 2022.
 Additionally, as of February 9, 2023, the customers with the most significant aggregate amount of contract backlog associated
with our drilling contracts were Shell, Petrobras and Chevron Corporation (together with its affiliates, “Chevron”), representing
approximately 33 percent, 31 percent and 14 percent, respectively, of our total contract backlog.  See “Item 1A. Risk Factors—
Risks related to our business—We rely heavily on a relatively small number of customers and the loss of a significant customer
or a dispute that leads to the loss of a customer could have an adverse effect on our business.”

HUMAN CAPITAL RESOURCES

Worldwide workforce—As  of  December  31,  2022,  we  had  a  global  workforce  of  approximately  5,340  individuals,
including  approximately  300  contractors,  representing  57  nationalities.    At  December  31,  2022,  our  global  workforce  was
geographically distributed in 21 countries across five continents as follows: 38 percent in North America, 30 percent in Europe,
19 percent in South America, 8 percent in Asia and 5 percent in Africa.

Labor  rights—We  respect  the  labor  rights  of  all  individuals  in  our  workforce,  including  the  right  to  collective
bargaining.  As of December 31, 2022, approximately 43 percent of our total workforce, working primarily in Norway, Brazil
and  the  U.K.,  are  represented  by,  and  some  of  our  contracted  labor  work  is  subject  to,  collective  bargaining  agreements,
substantially all of which are subject to annual salary negotiation.  Negotiations over annual salary or other labor matters could
result  in  higher  personnel  or  other  costs  or  increased  operational  restrictions  or  disruptions.    The  outcome  of  any  such
negotiation generally affects the market for all offshore employees, not only union members.  A failure to reach an agreement
on certain key issues could result in strikes, lockouts or other work stoppages.

Attraction,  development  and  retention—We  aim  to  strategically  cultivate  a  best-in-class  workforce  to  offer  the
innovation, local knowledge and experience required of the world’s premier offshore drilling contractor.  We seek to maintain
our  competitive  advantage  while  benefitting  our  local  communities  by  offering  regionally  competitive  compensation  and
benefits packages, a technically challenging work environment, global opportunities, and rotational development programs.  We
continually assess and adapt our offerings and our policies, based on evolving social and technological practices, to provide a
modern work environment, which is essential to attract and retain top talent, and a respectful and inclusive work environment in
which our global workforce can thrive.  Our focus on the quality of our workforce is designed to maximize the quality of our
work performance and ultimately, the value we deliver to our stakeholders.

Training—We  invest  in  our  workers  by  providing  them  with  the  transferrable  skill  sets  essential  to  advancing  their
professional  development.    To  optimize  the  competitive  position  of  our  business,  we  maintain  a  rigorous  competency-based
training program.  Our internal training board maintains and regularly updates our training matrix to meet or exceed industry
standards,  and  it  oversees  our  competency  assurance  management  system,  which  is  accredited  by  the  Offshore  Petroleum
Industry Training Organization.  We provide various offshore training formats designed to encompass all learning styles through
on-the-job, e-learning, customer-specific training, certifications, and leadership and licensing programs.  Setting us apart from
our competitors, we also offer unique simulation-based education, augmented by digital twin modeling, enabling our workforce
to  more  accurately  visualize  equipment  performance  and  target  efficiencies.    We  clearly  articulate  to  our  workforce  the
certifications,  skills  and  competencies  needed  for  each  role,  and  workers  are  required  to  successfully  complete  the  relevant
training and attain necessary certifications prior to taking on new roles.

Wellness and benefits—We offer our workforce regionally competitive medical and financial benefits, tailored to our
workforce  demographics.   We  design  our  wellness  and  benefits  strategy  under  four  pillars  consisting  of  physical  well-being,
financial well-being, emotional well-being and social well-being, including our globally available employee assistance program.

Safety—Our safety vision is to conduct our operations in an incident-free workplace, all the time, everywhere.  As a
socially responsible company, we prioritize the protection of everyone aboard our rigs and in our facilities, the environment and
our  property  at  all  work  locations  and  during  all  operations.    We  require  compliance  with  all  local  regulations  and  a
comprehensive set of internal policies and procedures that govern our operations.  With regular competency and effectiveness
assessments, our highly trained crews are equipped to protect our operational integrity with the process-driven management of
hazards to prevent and mitigate major accidents.  We measure our safety performance in terms of widely accepted ratios with
the  use  of  industry  standards,  including  (a)  the  total  recordable  incident  rate  (“TRIR”),  which  represents  the  number  of
recordable work-related injuries or illnesses for every 200,000 hours worked, and (b) the lost time incident rate (“LTIR”), which
measures  the  number  of  incidents  that  result  in  lost  time  due  to  work-related  injuries  or  illnesses  for  every  200,000  hours
worked.  In the years ended December 31, 2022 and 2021, our TRIR was 0.21 and 0.26, respectively, and our LTIR was 0.00
and 0.02, respectively.

ENVIRONMENTAL RESPONSIBILITY

We  strive  to  deliver  services  in  a  manner  that  both  minimizes  the  impact  our  business  has  on  the  environment  and
supports the interests of our stakeholders.  We continuously seek new ways to advance our commitment to safely performing
operations  while  simultaneously  safeguarding  the  environment.    We  maintain  a  global  Environmental  Management  System
(“EMS”) standard that is applied to our rigs, offices and facilities.  The EMS is aligned to ISO 14001 and provides a framework
to ensure that our worldwide operations are managed consistently and continuously in an environmentally responsible manner.
 We regularly assess the environmental impact of operations, focusing on the reduction of greenhouse gas emissions, operational
discharges, water use and waste.  Accordingly, we intend to reduce Scope 1 and Scope 2 greenhouse gas emissions intensity by
40 percent from 2019 levels by 2030.  Achieving these targets will require investments over time that result in the development
and  implementation  of  new  technologies,  reduced  fuel  consumption  and  other  initiatives  that  enable  us  to  optimize  power
management capabilities.

TECHNOLOGICAL INNOVATION

We have a long history of technological innovation, including the first dynamically positioned drillship, the first rig to
drill year-round in the North Sea, the first semisubmersible rig for year-round sub-Arctic operations, the first 10,000-ft. water
depth  rated  ultra-deepwater  drillship  and  numerous  water  depth  world  records  over  the  past  several  decades.    Twenty-
two drillships and two semisubmersibles in our existing fleet are, and our two drillships under construction will be, equipped
with our patented dual-activity technology, which allows our rigs to perform simultaneous drilling tasks in a parallel rather than
sequential manner, reducing well construction critical path activities and, thereby, improving efficiency in both exploration and
development drilling.

We  develop  and  deploy  industry-leading  technology  in  the  pursuit  of  delivering  safer,  more  efficient  and
environmentally responsible drilling services.  In addition to our patented dual-activity drilling technology, one of our drillships
has, and one drillship under

- 6 -

Table of Contents

construction  will  have,  industry-leading  3.4  million-pound  hoisting  load  capability.    Six  of  our  drillships  and  one  of  our
drillships  under  construction  include  hybrid  energy  storage  systems  for  enhanced  drill  floor  equipment  reliability,  fuel  and
emissions savings as well as advanced generator protection for power plant reliability.  Eleven drillships in our existing fleet
are, and one of our drillships under construction will be, outfitted with dual blowout preventers and triple liquid mud systems.
 Six drillships in our existing fleet are designed to accept 20,000 psi blowout preventers in the future, and one of our drillships
under  construction  will  be  equipped  with  dual  20,000  psi  blowout  preventers  and  related  equipment.    We  also  continue  to
develop  and  invest  in  technologies  designed  to  optimize  our  performance,  deliver  ever  improving  operational  integrity  and
reduce our carbon emissions.

Seven of our harsh environment semisubmersibles are designed and constructed specifically to provide highly efficient
performance in harsh environments.  We have installed automated drilling control systems on six harsh environment floaters,
which materially improves our ability to safely and efficiently deliver wells to our customers.

We  employ  a  data-driven  approach  by  deploying  technology,  augmented  by  the  size  of  our  fleet,  to  expand  our
knowledge framework for sustainable process optimization.  In 2020, we deployed our smart equipment analytics tool, which
delivers real-time data feeds from equipment to monitor equipment health, inferred emissions and energy consumption while
identifying  performance  trends  that  allow  us  to  systematically  optimize  equipment  maintenance  and  achieve  higher  levels  of
reliability, operational efficiency and sustainability.

Driven  by  our  continued  focus  on  safety,  we  developed  and,  on  five  of  our  drilling  units,  deployed  our  patented
HaloGuard℠  system,  which  alarms,  notifies  and,  if  required,  halts  equipment  to  avoid  injury  to  personnel  who  move  into
danger  zones.    We  recently  deployed  the  first  unit  of  Enhanced  Drilling’s  EC-Monitor  system  to  an  offshore  installation,
enabling highly accurate understanding of well fluid dynamics and improving the efficiency and accuracy of flow-checking and
detecting flow anomalies.  Additionally, in 2021, we deployed on one of our ultra-deepwater drillships the first kinetic blowout
stopper, a step-changing technology that promotes operations integrity and enterprise risk reduction through unrivaled shearing
capability.  In 2022, we deployed an offshore robotic riser bolting tool on two of our ultra-deepwater drillships, improving our
ability to deliver safe and efficient operations to our customers.

We  believe  our  efforts  to  continuously  improve,  and  effectively  use,  innovative  technologies  to  meet  or  exceed  our
customers’  requirements  is  critical  to  maintaining  our  competitive  position  within  the  contract  drilling  services  industry  by
ensuring the safety of our crews, drilling more efficient wells, building greater resilience into our critical operating systems and
reducing fuel consumption and emissions.

JOINT VENTURE, AGENCY AND SPONSORSHIP RELATIONSHIPS AND OTHER INVESTMENTS

In some areas of the world, local customs and practice or governmental requirements necessitate the formation of joint
ventures  with  local  participation  since  local  laws  or  customs  in  those  areas  effectively  mandate  the  establishment  of  a
relationship  with  a  local  agent  or  sponsor.    When  appropriate  in  these  areas,  we  may  enter  into  agency  or  sponsorship
agreements.    We  also  invest  in  certain  companies  for  operational  and  strategic  purposes.    Some  of  these  joint  ventures  or
companies in which we are an investor are involved in researching and developing technology to improve efficiency, reliability,
sustainability and safety for our drilling and other activities or are involved in businesses developed to support renewable or
other energy alternatives.  We may or may not control these partially owned companies.  At December 31, 2022, we held partial
ownership  interests  in  companies  organized  in  the  Cayman  Islands,  the  U.S.,  Norway,  Canada  and  other  countries.    At
December  31,  2022,  among  other  equity  investments,  we  held  a  33  percent  ownership  interest  in  Orion,  an  unconsolidated
Cayman  Islands  exempted  company  that  owns  the  harsh  environment  semisubmersible  Transocean  Norge  and  we  held  a
20  percent  ownership  interest  in  Liquila,  an  unconsolidated  Bermuda  company  formed  to  construct,  own  and  operate  the
newbuild ultra-deepwater drillship Deepwater Aquila, which is currently under construction.

GOVERNMENTAL REGULATIONS

Our  operations  are  subject  to  a  variety  of  international,  national,  regional,  state  and  local  government  regulations,
including  environmental  regulations.    We  monitor  our  compliance  with  such  government  regulations  in  each  country  of
operation and, notwithstanding increases in governmental regulations, particularly general environmental regulations, we have
made and will continue to make the required expenditures to comply with current and future government requirements.  To date,
we have not incurred material costs to comply with such governmental regulations, and we do not expect to make any material
capital  expenditures  to  support  our  continued  compliance  in  the  year  ending  December  31,  2023,  or  any  other  period
contemplated at this time.  We do not believe that our compliance with such requirements will have a material adverse effect on
our competitive position, consolidated results of operations or cash flows.  We incorporate by reference herein the disclosures
on  government  regulations,  including  environmental  regulations,  contained  in  the  following  sections  of  this  annual  report  on

ITEM 1A.RISK FACTORS

RISKS RELATED TO OUR BUSINESS

OUR  BUSINESS  DEPENDS  ON  THE  LEVEL  OF  ACTIVITY  IN  THE  OFFSHORE  OIL  AND  GAS  INDUSTRY,
WHICH IS SIGNIFICANTLY AFFECTED BY VOLATILE OIL AND GAS PRICES AND OTHER FACTORS.

Our business depends on oil and gas exploration, development and production in offshore areas where we are capable
of operating.  Demand for our services depends on these activities and related expenditure levels that are directly affected by
trends in oil and, to a lesser extent, natural gas prices.  Oil and gas prices are extremely volatile and are affected by numerous
factors, including the following:

◾ worldwide  demand  for  oil  and  gas,  including  economic  activity  in  the  U.S.,  other  large  energy-consuming  markets  and  in
developing  and  emerging  markets,  which  was  significantly  impacted  by  COVID-19  and  the  governmental,  company  and
individual reactions thereto;

◾ the  ability  of  the  Organization  of  the  Petroleum  Exporting  Countries  (“OPEC”)  to  set  and  maintain  production  levels,

productive spare capacity and pricing among its members;

◾ the level of production in non-OPEC countries;
◾ inventory levels, and the cost and availability of storage and transportation of oil, gas and their related products;
◾ the policies, laws and regulations of various governments regarding exploration and development of their oil and gas reserves
and environmental matters, including those addressing alternative energy sources and the risks of global climate change;

◾ international sanctions on oil-producing countries, or the lifting of such sanctions;
◾ advances in exploration, development and production technology;
◾ the development, exploitation and market acceptance of alternative energy sources;
◾ the further development of shale technology to exploit oil and gas reserves;
◾ the discovery rate of new oil and gas reserves and the rate of decline of existing oil and gas reserves;
◾ accidents, adverse weather conditions, natural disasters and other similar incidents relating to the oil and gas industry; and
◾ the worldwide security and political environment, including uncertainty or instability resulting from an escalation or outbreak

of armed hostilities, civil unrest, acts of terrorism, public health threats or other crises.

Demand for our services is particularly sensitive to the level of exploration, development and production activity of,
and the corresponding capital spending by, energy companies, including national energy companies.  Prolonged reductions in oil
and natural gas prices could depress the immediate levels of exploration, development and production activity.  Perceptions of
longer-term  lower  oil  and  natural  gas  prices  by  energy  companies,  or  a  perception  that  the  demand  for  hydrocarbons  will
significantly  decrease  in  the  medium  to  long  term,  could  similarly  reduce  or  defer  major  expenditures  given  the  long-term
nature  of  many  large-scale  development  projects  and  capital  reinvestment  policies.    Lower  levels  of  activity  result  in  a
corresponding  decline  in  the  demand  for  our  services,  which  could  have  a  material  adverse  effect  on  our  revenue  and
profitability.  Oil and gas prices and market expectations of potential changes in these prices significantly affect this level of
activity.  However, increases in near-term commodity prices do not necessarily translate into increased offshore drilling activity
since  customers’  expectations  of  longer-term  future  commodity  prices  and  expectations  regarding  future  demand  for
hydrocarbons typically have a greater impact on demand for our rigs.  Consistent with this dynamic, customers may delay or
cancel many exploration and development programs, resulting in reduced demand for our services.  Also, increased competition
for customers’ drilling budgets could come from, among other areas, land-based energy markets worldwide.  The availability of
quality drilling prospects, exploration success, relative production costs, the stage of reservoir development and political and
regulatory  environments  also  affect  customers’  drilling  campaigns.    Worldwide  military,  political  and  economic  events  have
often contributed to oil and gas price volatility and are likely to do so in the future.

THE OFFSHORE DRILLING INDUSTRY IS HIGHLY COMPETITIVE AND CYCLICAL, WITH INTENSE PRICE
COMPETITION.

The offshore contract drilling industry is highly competitive with numerous industry participants, none of which has a
dominant  market  share.    Drilling  contracts  are  traditionally  awarded  on  a  competitive  bid  basis.    Although  rig  availability,
service quality and technical capability are drivers of customer contract awards, bid pricing and intense price competition are
often key determinants for which a qualified contractor is awarded a job.

The  offshore  drilling  industry  is  highly  cyclical  and  is  impacted  by  oil  and  natural  gas  price  levels  and  volatility.
  Periods  of  high  customer  demand,  limited  rig  supply  and  high  dayrates  have  been  followed  by  periods  of  low  customer
demand,  excess  rig  supply  and  low  dayrates.    Changes  in  commodity  prices  can  have  a  dramatic  effect  on  rig  demand,  and
periods of excess rig supply may intensify competition in the industry and result in the idling of older and less technologically
advanced equipment.  We have idled and stacked rigs, and may in the future idle or stack additional rigs or enter into lower
dayrate drilling contracts in response to market conditions.  Idled or stacked rigs may remain out of service for extended periods
of  time.    During  prior  periods  of  high  dayrates  and  rig  utilization  rates,  we  and  other  industry  participants  responded  to
increased customer demand by increasing the supply of rigs through ordering the construction of new units.  The introduction of
new units delivered without contracts, combined with an increased number of rigs in the global market completing contracts and
becoming idle, would intensify price competition.  During periods of low oil and natural gas price levels, new construction has
resulted  in  an  oversupply  of  rigs  and  has  caused  a  subsequent  decline  in  dayrates  and  rig  utilization  rates,  sometimes  for
extended periods of time.  In an oversupplied market, we may have limited bargaining power to negotiate on more favorable
terms.  Additionally, lower market dayrates and intense price competition may drive customers to seek to renegotiate existing
contracts  to  reduce  dayrates  in  exchange  for  longer  contract  terms.    Lower  dayrates  and  rig  utilization  rates  could  adversely
affect our revenues and profitability.

As  of  February  9,  2023,  we  have  13  uncontracted  rigs,  of  which  five  have  been  out  of  service  for  greater  than
five years, and these rigs may remain out of service for extended periods of time.  We also have a noncontrolling ownership
interest  in  a  company  that  has  an  uncontracted  newbuild  drillship  under  construction.    If  we  are  unable  to  obtain  drilling
contracts for our uncontracted rigs, whether due to a prolonged offshore drilling market downturn, a delayed or muted recovery
of such market or otherwise, it may have an adverse effect on our results of operations and cash flows.

WE  MAY  NOT  BE  ABLE  TO  RENEW  OR  OBTAIN  NEW  DRILLING  CONTRACTS  FOR  RIGS  WHOSE
CONTRACTS ARE EXPIRING OR OBTAIN DRILLING CONTRACTS FOR OUR STACKED AND IDLE RIGS.

The offshore drilling markets in which we compete experience fluctuations in the demand for drilling services.  Our
ability  to  renew  expiring  drilling  contracts  or  obtain  new  drilling  contracts  depends  on  the  prevailing  or  expected  market
conditions.  As of February 9, 2023, we have 13 stacked or idle rigs.  We also have seven existing drilling contracts for our rigs
that  are  currently  operating,  which  are  scheduled  to  expire  before  December  31,  2023.   We  may  be  unable  to  obtain  drilling
contracts for our rigs that are currently operating upon the expiration or termination of such contracts, and there may be a gap in
the operation of the rigs between the current contracts and subsequent contracts.  When oil and natural gas prices are low or it is
expected that such prices will decrease in the future, we may be unable to obtain drilling contracts at attractive dayrates or at all.
 We may not be able to obtain new drilling contracts with the terms or dayrates sufficient to support a reactivation of a cold
stacked  rig.    Likewise,  we  may  not  be  able  to  obtain  new  drilling  contracts  in  direct  continuation  with  existing  contracts,  or
depending  on  prevailing  market  conditions,  we  may  enter  into  drilling  contracts  at  dayrates  substantially  below  the  existing
dayrates or on terms otherwise less favorable compared to existing contract terms, which may have an adverse effect on our
financial position, results of operations or cash flows.

OUR CURRENT BACKLOG OF CONTRACT DRILLING REVENUES MAY NOT BE FULLY REALIZED.

At  February  9,  2023,  our  contract  backlog  was  approximately  $8.54  billion.    This  amount  represents  the  maximum
contractual operating dayrate multiplied by the number of days remaining in the firm contract period, excluding revenues for
mobilization,  demobilization,  contract  preparation,  other  incentive  provisions  or  reimbursement  revenues,  which  are  not
expected  to  be  significant  to  our  contract  drilling  revenues.    Our  contract  backlog  includes  amounts  associated  with  our
one  contracted  newbuild  unit  that  is  currently  under  construction.   The  contractual  operating  dayrate  may  be  higher  than  the
actual dayrate we ultimately receive or an alternative contractual dayrate, such as waiting on weather rate, repair rate, standby
rate or force majeure rate, may apply under certain circumstances.  The contractual operating dayrate may also be higher than
the  actual  dayrate  we  ultimately  receive  due  to  a  number  of  factors,  including  rig  downtime  or  suspension  of  operations.
  Several  factors  could  cause  rig  downtime  or  a  suspension  of  operations,  including:  equipment  breakdowns  and  other
unforeseen engineering problems, labor strikes and other work stoppages, shortages of material and skilled labor, surveys by
government and maritime authorities, periodic classification surveys, severe weather or harsh operating conditions, and force
majeure events.

In certain drilling contracts, the dayrate may be reduced to zero if, for example, repairs extend beyond a stated period
of time.  Our contract backlog includes only firm commitments, which are represented by signed drilling contracts or, in some
cases, other definitive agreements awaiting contract execution.  We may not be able to realize the full amount of our contract
backlog  due  to  events  beyond  our  control.    In  addition,  some  of  our  customers  have  experienced  liquidity  issues  in  the  past,
including  some  recently,  and  these  liquidity  issues  could  be  experienced  again  if  commodity  prices  decline  for  an  extended
period of time.  Liquidity issues and other market pressures could lead our customers to seek bankruptcy protection or to seek to
repudiate, cancel or renegotiate these agreements for various reasons (see “—Our drilling contracts may be terminated due to a
number  of  events,  and,  during  depressed  market  conditions,  our  customers  may  seek  to  repudiate  or  renegotiate  their
contracts”).    Our  inability  to  realize  the  full  amount  of  our  contract  backlog  may  have  an  adverse  effect  on  our  financial
position, results of operations or cash flows.

WE  MUST  MAKE  SUBSTANTIAL  CAPITAL  AND  OPERATING  EXPENDITURES  TO  REACTIVATE  OUR
STACKED  OR  IDLE  FLEET  AND  TO  MAINTAIN  OUR  ACTIVE  FLEET,  AND  WE  MAY  BE  REQUIRED  TO
MAKE SIGNIFICANT CAPITAL EXPENDITURES TO MAINTAIN OUR COMPETITIVENESS AND TO COMPLY
WITH  LAWS  AND  APPLICABLE  REGULATIONS  AND  STANDARDS  OF  GOVERNMENTAL  AUTHORITIES
AND ORGANIZATIONS.

We must make substantial capital and operating expenditures to maintain our active fleet or to reactivate our stacked or
idle  fleet.    These  expenditures  could  increase  as  a  result  of  changes  in  the  cost  of  labor  and  materials,  requirements  of
customers, the size of our fleet, the cost of replacement parts for existing rigs, the geographic location of the rigs and the length
of  drilling  contracts.    Changes  in  offshore  drilling  technology,  customer  requirements  for  new  or  upgraded  equipment  and
competition  within  our  industry  may  require  us  to  make  significant  capital  expenditures  in  order  to  maintain  our
competitiveness  and  to  achieve  our  intention  to  reduce  our  greenhouse  gas  emission  intensity.    Changes  in  governmental
regulations, including environmental requirements, and changes in safety or other equipment standards, as well as compliance
with standards imposed by maritime self-regulatory organizations, may cause our capital expenditures to increase or require us
to  make  additional  unforeseen  capital  expenditures.   As  a  result  of  these  factors,  we  may  be  required  to  take  our  rigs  out  of
service for extended periods of time, with corresponding losses of revenues, in order to make such alterations or to add such
equipment.  In the future, market conditions may not justify these expenditures or enable us to operate our older rigs profitably
during the remainder of their economic lives.

If  we  are  unable  to  fund  capital  expenditures  with  our  cash  flows  from  operations  or  proceeds  from  sales  of  non-
strategic  assets,  we  may  be  required  to  either  incur  additional  borrowings  or  raise  capital  through  the  sale  of  debt  or  equity
securities, or additional financing arrangements with banks or other capital providers.  Our ability to access the capital markets
may be limited by our financial condition at the time, perceptions of us or our industry, by changes in laws and regulations or
interpretation thereof and by adverse market conditions resulting from, among other things, general economic conditions and
contingencies and uncertainties that are beyond our control.  If we raise funds by issuing equity securities or other securities that
are  convertible  into  equity  securities,  existing  shareholders  may  experience  dilution.    Our  failure  to  obtain  the  funds  for
necessary future capital expenditures could have a material adverse effect on our business and on our financial position, results
of operations and cash flows.

OUR OPERATING AND MAINTENANCE COSTS WILL NOT NECESSARILY FLUCTUATE IN PROPORTION TO
CHANGES IN OUR OPERATING REVENUES.

Our operating and maintenance costs will not necessarily fluctuate in proportion to changes in our operating revenues
and  are  affected  by  many  factors,  including  inflation.    Costs  for  operating  a  rig  are  generally  fixed  or  only  semi-variable
regardless of the dayrate being earned.  To the extent a drilling contract provides for escalations attributable to inflation in our
costs,  those  adjustments  will  lag  the  impact  of  inflationary  pressures  and  may  not  reflect  the  full  impact  to  us  of  any  cost
inflation.   As  drilling  contracts  with  such  provisions  expire  or  are  terminated,  there  can  be  no  assurance  that  future  drilling
contracts will contain similar provisions, which may reduce our margins in inflationary environments.  In addition, should our
rigs incur unplanned downtime while on contract or idle time between drilling contracts, we will not always reduce the staff on
those rigs because we could use the crew to prepare the rig for its next contract.  During times of reduced activity, reductions in
costs may not be immediate because portions of the crew may be required to prepare rigs for stacking, after which time the crew
members may be reassigned to active rigs or released.  As our rigs are mobilized from one geographic location to another, the
labor and other operating and maintenance costs can vary significantly.  In general, labor costs increase primarily due to higher
salary levels and inflation.  Equipment maintenance costs fluctuate depending upon the type of activity the unit is performing
and the age and condition of the equipment, and these costs could increase for short or extended periods as a result of regulatory
or  customer  requirements  that  raise  maintenance  standards  above  historical  levels.    The  amount  of  contract  preparation  and
reactivation costs vary based on the scope and length of the contract preparation or reactivation project, and the recognition of
such costs varies depending on the duration of the firm contractual period and other contract terms.

Certain of our drilling contracts are partially payable in local currency.  The amounts, if any, of local currency received
under these drilling contracts may exceed our local currency needs to pay local operating and maintenance costs, leading to an
accumulation  of  excess  local  currency  balances,  which,  in  certain  instances,  may  be  subject  to  either  restrictions  or  other
difficulties  in  converting  to  U.S.  dollars,  our  functional  currency,  or  to  other  currencies  of  the  locations  where  we  operate.
 Excess amounts of local currency may also be exposed to the risk of currency exchange losses.

PUBLIC  AND  INVESTOR  SENTIMENT  TOWARDS  CLIMATE  CHANGE,  FOSSIL  FUELS  AND  OTHER  ESG
MATTERS  COULD  ADVERSELY  AFFECT  OUR  BUSINESS,  COST  OF  CAPITAL  AND  THE  PRICE  OF  OUR
STOCK AND OTHER SECURITIES.

Changing public sentiment concerning fossil fuels, aimed at the investment community, including investment advisors,
sovereign wealth funds, public pension funds, universities and other groups, has prompted efforts to promote the divestment of
shares of energy companies, as well as to pressure lenders and other financial services companies to limit or curtail activities
with energy companies.  These efforts have recently intensified, as demonstrated by the State of New York’s December 2020
announcement  that  it  will  be  divesting  the  state’s  Common  Retirement  Fund  from  fossil  fuels  by  2040.    If  this  or  similar
divestment efforts are successful, our stock price and our ability to access capital markets may be negatively impacted.

Members  of  the  investment  community  are  also  increasing  their  focus  on  environmental,  social  and  governance
(“ESG”) practices and disclosures, including practices and disclosures related to greenhouse gases and climate change, in the
energy industry in particular, and diversity and inclusion initiatives and governance standards among public companies more
generally.  As a result, we may face

- 10 -

Table of Contents

increasing  pressure  regarding  our  ESG  disclosures  and  practices.   Additionally,  members  of  the  investment  community  may
screen companies such as ours for ESG sustainability performance before investing in our stock.  Over the past few years there
has also been an acceleration in investor demand for ESG investing opportunities, and many large institutional investors have
committed to increasing the percentage of their portfolios that are allocated towards ESG investments.  As a result, there has
been a proliferation of ESG focused investment funds seeking ESG oriented investment products.  If we or our securities are
unable to meet the sustainability ESG standards or investment criteria set by these investors and funds, we may lose investors or
investors  may  allocate  a  portion  of  their  capital  away  from  us,  our  cost  of  capital  may  increase,  our  stock  price  may  be
negatively  impacted,  the  cost  of  capital  associated  with  our  securities  offerings  may  increase  and  our  reputation  may  be
negatively affected.

PUBLIC  HEALTH  THREATS  HAVE  HAD,  AND  MAY  CONTINUE  TO  HAVE,  SIGNIFICANT  ADVERSE
CONSEQUENCES FOR GENERAL ECONOMIC, FINANCIAL AND BUSINESS CONDITIONS, AS WELL AS FOR
OUR BUSINESS AND OPERATIONS.

Public health threats, including pandemics and epidemics, such as the outbreak of COVID-19, new variants thereof,
severe influenza, other coronaviruses and other highly communicable viruses or diseases, have impacted and may continue to
impact  our  operations  directly  or  indirectly,  including  by  disrupting  the  operations  of  our  business  partners,  suppliers  and
customers in ways that adversely impact our operations.  Such impacts may include, among others:

◾ causing a temporary shut-down of operations in case of an outbreak on one or more of our rigs;
◾ disrupting or restricting the ability of our suppliers, manufacturers and service providers to supply parts, equipment labor or

services in the jurisdictions in which we operate or conduct shipyard activities including newbuild construction;

◾ causing us to incur increased costs, inefficiencies, and labor shortages as a result of precautionary measures taken to counteract

a potential or actual outbreak, including testing and quarantining of offshore personnel; and

◾ being negatively affected by various actions by governmental authorities around the world designed to prevent or reduce the
spread  of  an  outbreak,  such  as  imposing  mandatory  closures  of  all  business  facilities  deemed  to  be  non-essential,  seeking
voluntary  closures  of  such  facilities  and  imposing  restrictions  on,  or  issuing  advisories  with  respect  to,  travel,  business
operations and public gatherings or interactions.

As a result, we may experience significant adverse consequences in our ability to meet our commitments to customers,
including  due  to  increased  operating  costs  and  increased  risk  of  rig  downtime  or  contract  termination,  which  may  result  in
substantial  adverse  consequences  for  our  business  and  results  of  operations.    In  addition,  public  health  threats  may  result  in
significantly reduced global or regional economic activity, which could result in a sharp reduction in the demand for oil and an
associated decline in oil prices as occurred during 2020.  Such conditions may result in, reductions to our customers’ drilling
and production expenditures and delays or cancellations of projects, which may cause a decrease in demand for our services and
an increase in the risk that our customers may seek to terminate or renegotiate pricing or other terms for our existing contracts
or that more of our rigs may become idle, stacked or retired from our fleet.

The  magnitude  and  duration  of  potential  social,  economic  and  labor  instability  resulting  from  such  public  health
threats,  including  the  speed  at  which  national  economies  can  recover,  or  whether  any  recovery  will  ultimately  experience  a
reversal or other setbacks, are uncertain and cannot be estimated as such effects depend on future events that would be largely
out of our control.

WE  RELY  HEAVILY  ON  A  RELATIVELY  SMALL  NUMBER  OF  CUSTOMERS  AND  THE  LOSS  OF  A
SIGNIFICANT CUSTOMER OR A DISPUTE THAT LEADS TO THE LOSS OF A CUSTOMER COULD HAVE AN
ADVERSE EFFECT ON OUR BUSINESS.

We engage in offshore drilling services for most of the leading integrated energy companies or their affiliates, as well
as for many government-owned or government-controlled energy companies and other independent energy companies.  For the
year ended December 31, 2022, our most significant customers were Shell, Equinor and Petrobras, representing approximately
33  percent,  25  percent  and  11  percent,  respectively,  of  our  consolidated  operating  revenues.    As  of  February  9,  2023,  the
customers  with  the  most  significant  aggregate  amount  of  contract  backlog  associated  with  our  drilling  contracts  were  Shell,
Petrobras and Chevron, representing approximately 33 percent, 31 percent, and 14 percent, respectively, of our total contract
backlog.  The loss of any of these customers or another significant customer, or a decline in payments under any of our drilling
contracts, could, at least in the short term, have an adverse effect on our business.

OUR BUSINESS INVOLVES NUMEROUS OPERATING HAZARDS, AND OUR INSURANCE AND INDEMNITIES
FROM  OUR  CUSTOMERS  MAY  NOT  BE  ADEQUATE  TO  COVER  POTENTIAL  LOSSES  FROM  OUR
OPERATIONS.

Our operations are subject to the usual hazards inherent in the drilling of oil and gas wells, such as, blowouts, reservoir
damage, loss of production, loss of well control, lost or stuck drill strings, equipment defects, craterings, fires, explosions and
pollution.  Contract drilling requires the use of heavy equipment and exposure to hazardous conditions, which may subject us to
liability  claims  by  employees,  customers  and  other  parties.    These  hazards  can  cause  personal  injury  or  loss  of  life,  severe
damage  to  or  destruction  of  property  and  equipment,  pollution  or  environmental  or  natural  resource  damage,  claims  by  third
parties or customers and suspension of operations.  Our offshore fleet is also subject to hazards inherent in marine operations,
either while on site or during mobilization, such as capsizing, sinking, grounding, collision, piracy, damage from severe weather
and marine life infestations.

The  U.S.  Gulf  of  Mexico,  the  South  China  Sea  and  the  Northwest  Coast  of  Australia  are  areas  subject  to  typhoons,
hurricanes  or  other  extreme  weather  conditions  on  a  relatively  frequent  basis,  and  our  drilling  rigs  in  these  regions  may  be
exposed to damage or total loss by these storms, some of which may not be covered by insurance.  The occurrence of these
events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury to or
death of rig personnel.  Some experts believe global climate

- 11 -

Table of Contents

change  could  increase  the  frequency  and  severity  of  these  extreme  weather  conditions.    Operations  may  also  be  suspended
because  of  machinery  breakdowns,  abnormal  drilling  conditions,  failure  of  subcontractors  to  perform  or  supply  goods  or
services, or personnel shortages.  We customarily provide contract indemnity to our customers for certain claims that could be
asserted by us relating to damage to or loss of our equipment, including rigs, and claims that could be asserted by us or our
employees relating to personal injury or loss of life.

Damage to the environment or natural resources could also result from our operations, particularly through spillage of
hydrocarbons, fuel, lubricants or other chemicals and substances used in drilling operations, or extensive uncontrolled fires.  We
may also be subject to property damage, environmental indemnity and other claims by energy companies or other third parties.
 Drilling involves certain risks associated with the loss of control of a well, such as blowout, cratering, the cost to regain control
of  or  redrill  the  well  and  remediation  of  associated  pollution.    Our  customers  may  be  unable  or  unwilling  to  indemnify  us
against such risks.  In addition, a court may decide that certain indemnities in our current or future drilling contracts are not
enforceable.  The law generally considers contractual indemnity for criminal fines and penalties to be against public policy, and
the enforceability of an indemnity as to other matters may be limited.

Our insurance policies and drilling contracts contain rights to indemnity that may not adequately cover our losses, and
we do not have insurance coverage or rights to indemnity for all risks.  We have two main types of insurance coverage: (1) hull
and machinery coverage for physical damage to our property and equipment and (2) excess liability coverage, which generally
covers  offshore  risks,  such  as  personal  injury,  third-party  property  claims,  and  third-party  non-crew  claims,  including  wreck
removal and pollution.  We generally have no hull and machinery insurance coverage for damages caused by named storms in
the U.S. Gulf of Mexico.  We maintain per occurrence deductibles that generally range up to $10 million for various third-party
liabilities,  and  we  self-insure  $50  million  of  the  $750  million  excess  liability  coverage  through  our  wholly  owned  captive
insurance company.  We also retain the risk for any liability that exceeds our excess liability coverage.  However, pollution and
environmental risks generally are not completely insurable.

If  a  significant  accident  or  other  event  occurs  that  is  not  fully  covered  by  our  insurance  or  by  an  enforceable  or
recoverable  indemnity,  the  occurrence  could  adversely  affect  our  financial  position,  results  of  operations  or  cash  flows.   The
amount of our insurance may also be less than the related impact on enterprise value after a loss.  Our insurance coverage will
not in all situations provide sufficient funds to protect us from all liabilities that could result from our drilling operations.  Our
coverage  includes  annual  aggregate  policy  limits.   As  a  result,  we  generally  retain  the  risk  for  any  losses  in  excess  of  these
limits.    We  generally  do  not  carry  insurance  for  loss  of  revenue,  and  certain  other  claims  may  also  not  be  reimbursed  by
insurance carriers.  Any such lack of reimbursement may cause us to incur substantial costs.  In addition, we could decide to
retain  more  risk  in  the  future,  resulting  in  higher  risk  of  losses,  which  could  be  material.    Moreover,  we  may  not  be  able  to
maintain  adequate  insurance  in  the  future  at  rates  that  we  consider  reasonable  or  be  able  to  obtain  insurance  against  certain
risks.

OUR  DRILLING  CONTRACTS  MAY  BE  TERMINATED  DUE  TO  A  NUMBER  OF  EVENTS,  AND,  DURING
DEPRESSED  MARKET  CONDITIONS,  OUR  CUSTOMERS  MAY  SEEK  TO  REPUDIATE  OR  RENEGOTIATE
THEIR CONTRACTS.

Certain of our drilling contracts with customers may be cancelable at the option of the customer upon payment of an
early termination payment.  Such payments may not, however, fully compensate us for the loss of the contract.  For example,
early in the fourth quarter of 2022, Transocean Equinox concluded the activities contemplated in its drilling contract prior to the
end  of  the  contract’s  firm  term  that  was  previously  expected  late  in  the  fourth  quarter  of  2022.    The  termination  payment
associated with the drilling contract would not fully compensate us for the early termination of the contract.  Drilling contracts
also  customarily  provide  for  either  automatic  termination  or  termination  at  the  option  of  the  customer,  typically  without  the
payment of any termination fee, under various circumstances such as non-performance, as a result of significant downtime or
impaired performance caused by equipment or operational issues, or sustained periods of downtime due to force majeure events,
many of which are beyond our control.  Certain customers who seek to terminate our drilling contracts may attempt to defeat or
circumvent  our  protections  against  certain  liabilities.    Our  customers’  ability  to  perform  their  obligations  under  their  drilling
contracts, including their ability to fulfill their indemnity obligations to us, may also be negatively impacted by an economic
downturn.  Our customers, which include national energy companies, often have significant bargaining leverage over us.  If our
customers cancel some of our contracts, and we are unable to secure new contracts on a timely basis and on substantially similar
terms, or if contracts are suspended for an extended period of time or if a number of our contracts are renegotiated on terms that
are not as favorable as current terms, it could adversely affect our financial position, results of operations or cash flows.

During periods of depressed market conditions, such as we have recently experienced, we are subject to an increased
counterparty risk, as our customers may seek to repudiate their contracts, including through claims of non-performance in order
to reduce their capital expenditures.  Our customers may no longer need a drilling rig that is currently under contract or may be
able to obtain a comparable drilling rig at a lower dayrate.  We have experienced, and are at continued risk of experiencing,
early contract terminations when there is a weak commodity price environment.  The ability of each of our counterparties to
perform its obligations under a contract with us, including indemnity obligations, will depend on a number of factors that are
beyond our control and may include, among other things, general economic conditions, the condition of the offshore drilling
industry, prevailing prices for oil and natural gas, the overall financial condition of the counterparty, the dayrates received and
the level of expenditures necessary to maintain drilling activities.  Should a counterparty fail to honor its obligations under an
agreement with us, we could sustain losses, which could have an adverse effect on our business and on our financial position,
results of operations or cash flows.

FAILURE TO RECRUIT AND RETAIN PERSONNEL COULD HURT OUR OPERATIONS.

We depend on the continuing efforts of key members of our management, as well as other highly skilled personnel, to
operate  and  provide  technical  services  and  support  for  our  business  worldwide.    Historically,  competition  for  the  personnel
required for drilling operations has intensified as the number of rigs activated, added to worldwide fleets or under construction
increased,  leading  to  shortages  of  qualified  personnel  in  the  industry  and  creating  upward  pressure  on  wages  and  higher
turnover.  We may experience a reduction in the experience level of our personnel as a result of any increased turnover, which
could  lead  to  higher  downtime  and  more  operating  incidents,  which  in  turn  could  decrease  revenues  and  increase  costs.    If
increased competition for qualified personnel were to intensify in the future we may experience increases in costs or limits on
operations.

OUR  LABOR  COSTS  AND  THE  OPERATING  RESTRICTIONS  UNDER  WHICH  WE  OPERATE  COULD
INCREASE  AS  A  RESULT  OF  COLLECTIVE  BARGAINING  NEGOTIATIONS  AND  ADDITIONAL
UNIONIZATION EFFORTS.

As of December 31, 2022, approximately 43 percent of our total workforce, working primarily in Norway, Brazil and
the  U.K.,  are  represented  by,  and  some  of  our  contracted  labor  work  is  subject  to,  collective  bargaining  agreements,
substantially all of which are subject to annual salary negotiation.  Negotiations over annual salary or other labor matters could
result  in  higher  personnel  or  other  costs  or  increased  operational  restrictions  or  disruptions.    The  outcome  of  any  such
negotiation  generally  affects  the  market  for  all  offshore  employees,  not  only  the  union  members.    A  failure  to  reach  an
agreement on certain key issues could result in strikes, lockouts, or other work stoppages.  Legislation has been introduced in
the  U.S.  Congress  that  could  encourage  additional  unionization  efforts  in  the  U.S.,  as  well  as  increase  the  chances  that  such
efforts succeed.  Additional unionization efforts, if successful, new collective bargaining agreements or work stoppages could
materially increase our labor costs and operating restrictions.

OUR SHIPYARD PROJECTS AND OPERATIONS ARE SUBJECT TO DELAYS AND COST OVERRUNS.

We  have  a  variety  of  shipyard  projects  underway  for  our  existing  rigs  at  any  given  time.    Additionally,  as  of
February  14,  2023,  we  were  constructing  one  ultra-deepwater  drillship  and  held  a  noncontrolling  ownership  interest  in  a
company  that  is  constructing  one  ultra-deepwater  drillship.   These  shipyard  projects  are  subject  to  the  risks  of  delay  or  cost
overruns inherent in any such construction project resulting from numerous factors, including the following:

◾ complications  arising  from  pandemics  and  epidemics,  such  severe  influenza,  coronaviruses  and  other  highly  communicable
viruses  or  diseases,  and  associated  government  orders  in  the  country  where  the  rigs  are  being  constructed  or  serviced  and
elsewhere;

◾ shipyard availability, failures and difficulties;
◾ shortages of equipment, materials or skilled labor;
◾ failure  or  delayed  deliveries  of  significant  materials  or  equipment  for  various  reasons,  including  due  to  supplier  shortages,

constraints, disruption or quality issues;

◾ design and engineering problems, including those relating to the commissioning of newly designed equipment;
◾ latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions;
◾ unanticipated actual or purported change orders;
◾ disputes with shipyards and suppliers;
◾ availability of suppliers to recertify equipment for enhanced regulations;
◾ strikes, labor disputes and work stoppages;
◾ customer acceptance delays or delays in providing customer-supplied engineering, approvals or equipment;
◾ adverse weather conditions, including damage caused by such conditions;
◾ terrorist acts, war, piracy and civil unrest;
◾ unanticipated cost increases; and
◾ difficulty in obtaining necessary permits or approvals.

These factors may contribute to cost variations and delays in the delivery of rigs undergoing shipyard projects or any
future newbuild units.  Cost variations may result in, among other things, disputes with the shipyards that construct or service
our drilling units.  In addition, delayed delivery of our newbuild units or other rigs undergoing shipyard projects would impact
contract commencement, resulting in a loss of revenues we could earn, and may also cause customers to terminate or shorten
the term of the drilling contract for the rig pursuant to applicable late delivery clauses.  In the event of termination of any of
these drilling contracts, we may not be able to secure a replacement contract on as favorable terms, if at all.

Our operations also rely on a significant supply of capital and consumable spare parts and equipment to maintain and
repair our fleet.  We also rely on the supply of ancillary services, including supply boats and helicopters.  Our reliance on our
suppliers, manufacturers and service providers to secure equipment, parts, components and sub-systems used in our operations
exposes  us  to  volatility  in  the  quality,  prices  and  availability  of  such  items.    Certain  parts  and  equipment  that  we  use  in  our
operations may be available only from a small number of suppliers, manufacturers or service providers, or in some cases must
be sourced through a single supplier, manufacturer or service provider.  Some parts and equipment require long lead times to
obtain, and an unplanned failure or other need to replace any such parts and equipment may result in a longer than usual time to
obtain  them  or  require  us  to  pay  higher  costs  to  obtain  them  on  an  expedited  basis.   A  disruption  in  the  deliveries  from  our
suppliers,  manufacturers  or  service  providers,  capacity  constraints,  production  disruptions,  price  increases,  quality  control
issues, recalls or other decreased availability of parts and equipment or ancillary services could adversely affect our ability to
meet our commitments to customers, adversely impact our operations, increase our operating costs and result in increases in rig
downtime and delays in the repair and maintenance of our fleet.

AS  PART  OF  OUR  BUSINESS  STRATEGIES,  WE  MAY  PURSUE  OPPORTUNITIES  TO  STRENGTHEN  AND
BROADEN OUR BUSINESS THAT INCLUDE ACQUISITIONS OF BUSINESSES OR DRILLING RIGS, MERGERS
OR JOINT VENTURES OR OTHER INVESTMENTS, AND SUCH TRANSACTIONS WOULD PRESENT VARIOUS
RISKS AND UNCERTAINTIES.

We  may  pursue  transactions  that  involve  the  acquisition  of  businesses  or  assets,  mergers  or  joint  ventures  or  other
investments  that  we  believe  will  enable  us  to  further  strengthen  or  broaden  our  business.    Any  such  transaction  would  be
evaluated  on  a  case-by-case  basis,  and  the  consummation  thereof  would  be  dependent  upon  several  factors,  including
identifying  suitable  companies,  businesses  or  assets  that  align  with  our  business  strategies,  reaching  agreement  with  the
potential counterparties on acceptable terms, the receipt of any applicable regulatory and other approvals, and other conditions.
 These transactions involve various risks, including among others, (i) difficulties related to integrating or managing applicable
parts  of  an  acquired  business  or  joint  venture  and  unanticipated  changes  in  customer  and  other  third-party  relationships
subsequent  to  closing,  (ii)  diversion  of  management's  attention  from  day-to-day  operations,  (iii)  failure  to  realize  anticipated
benefits, such as cost savings, revenue enhancements or strengthening or broadening our business, (iv) potentially substantial
transaction costs associated with acquisitions, joint ventures or investments if we or a transaction counterparty seeks to exit or
terminate an interest in the joint venture or investment, and (v) potential accounting impairment or actual diminution or loss of
value of our investment if future market, business or other conditions ultimately differ from our assumptions at the time of such
transaction is consummated.

FAILURE  TO  EFFECTIVELY  AND  TIMELY  ADDRESS  THE  TRANSITION  TO  RENEWABLE  OR  OTHER
ALTERNATIVE ENERGY SOURCES, OR TO RESPOND TO OTHER CLIMATE RELATED BUSINESS TRENDS,
COULD ADVERSELY AFFECT OUR BUSINESS, RESULTS OF OPERATIONS AND CASH FLOWS.

Our  long-term  success  will  be  impacted  by  our  ability  to  effectively  address  the  transition  to  renewable  and  other
alternative energy sources, and our ability to respond to other climate-related business trends that could adversely impact the
long-term  demand  for  oil  and  natural  gas  and,  ultimately,  the  demand  for  our  services  and  products  from  our  services.
 Addressing  increased  focus  on  the  development  of  additional  alternative  energy  sources  and  other  climate-related  business
trends has required and will further require adapting certain parts of our operations to changing government requirements and
customer preferences.

We continue to engage with existing and potential customers and suppliers to develop or implement solutions designed
to reduce or decarbonize oil and gas operations, or to advance renewable and other alternative energy sources.  Nonetheless, as
it is not possible at this time to predict the timing, scope and effect of the development of and transition to renewable or other
alternative  energy  sources,  any  such  developments,  such  as  the  declining  cost  of  renewable  energy  generation  technologies,
could adversely impact the long-term global demand for oil and natural gas and, ultimately, the demand for our services and
products  from  our  services.    If  the  transition  to  alternative  energy  sources  or  other  climate-related  trends  change  faster  than
anticipated  or  develop  in  a  manner  that  we  do  not  anticipate,  our  business,  results  of  operations  and  cash  flows  could  be
adversely affected.  If we do not or are perceived to not effectively implement a strategy that incorporates alternative energy
sources, or if investors or financial institutions shift funding away from companies in fossil fuel-related industries, our access to
capital or the market for our securities could be negatively impacted.

OUR ASPIRATIONS, GOALS, COMMITMENT TARGETS AND INITIATIVES RELATED TO SUSTAINABILITY,
INCLUDING  EMISSIONS  REDUCTION,  AND  OUR  PUBLIC  STATEMENTS  AND  DISCLOSURES  REGARDING
THEM, EXPOSE US TO NUMEROUS RISKS.

We have developed, and will continue to develop and set, goals, targets, and other objectives related to sustainability
matters,  including  our  commitment  target  to  reduce  greenhouse  gas  emissions  intensity.    Statements  related  to  these  goals,
commitment targets and objectives reflect our current intentions and do not constitute a guarantee that they will be achieved.
 Our efforts to research, establish, accomplish, and accurately report on these goals, commitment targets, and other objectives
expose  us  to  numerous  operational,  reputational,  financial,  legal,  and  other  risks.    Our  ability  to  achieve  any  stated  goal,
commitment  target,  or  objective,  including  with  respect  to  emissions  intensity  reduction,  is  subject  to  numerous  factors  and
conditions, some of which are outside of our control.

Our business may face increased scrutiny from investors and other stakeholders related to our sustainability activities,
including  the  goals,  commitment  targets,  and  other  objectives  that  we  announce,  and  our  methodologies  and  timelines  for
pursuing  them.    If  our  sustainability  assumptions  or  practices  do  not  meet  investor  or  other  stakeholder  expectations  and
standards,  which  continue  to  evolve,  our  reputation,  our  ability  to  attract  or  retain  employees,  and  our  attractiveness  as  an
investment or business partner could be negatively affected.  Similarly, our failure or perceived failure to pursue or fulfill our
sustainability-focused goals, targets, and objectives, to comply with ethical, environmental, or other standards, regulations, or
expectations, or to satisfy various reporting standards with respect to these matters, within the timelines we announce, or at all,
could adversely affect our business or reputation, as well as expose us to government enforcement actions and private litigation.

RISKS RELATED TO OUR INDEBTEDNESS

WE  HAVE  A  SUBSTANTIAL  AMOUNT  OF  DEBT,  INCLUDING  SECURED  DEBT,  AND  WE  MAY  LOSE  THE
ABILITY TO OBTAIN FUTURE FINANCING AND SUFFER COMPETITIVE DISADVANTAGES.

At December 31, 2022 and 2021, our total debt was $7.35 billion and $7.17 billion, respectively, of which $2.19 billion
and  $2.30  billion,  respectively,  was  secured.   We  have  a  bank  credit  agreement  (as  amended,  the  “Secured  Credit  Facility”),
which is currently undrawn, the borrowings under which would be secured.  This substantial level of debt and other obligations
could have significant adverse consequences on our business and future prospects, including the following:

◾ we may be unable to obtain financing in the future to refinance our existing debt or for working capital, capital expenditures,

acquisitions, debt service requirements, distributions, share repurchases, or other purposes;

◾ we may be unable to use operating cash flow in other areas of our business because we must dedicate a substantial portion of

these funds to service the debt;

◾ we could become more vulnerable to general adverse economic and industry conditions, including increases in interest rates,

particularly given our substantial indebtedness, some of which bears interest at variable rates;

◾ we may be unable to meet financial ratios in the agreements governing certain of our debt facilities and finance lease or satisfy
certain  other  covenants  and  conditions  included  in  our  debt  agreements,  which  could  result  in  our  inability  to  meet
requirements for borrowings under our credit agreement or a default under these agreements, impose restrictions with respect
to our access to certain of our capital, and trigger cross default provisions in our other debt instruments;

◾ if  we  default  under  the  terms  of  our  secured  financing  arrangements,  the  secured  debtholders  may,  among  other  things,

foreclose on the collateral securing the debt, including the applicable drilling units;

◾ we  may  be  unable  to  obtain  new  investment  or  financing  given  recent  ESG-influenced  trends  among  many  financial
intermediaries, investors and other capital markets participants in reducing, or ceasing, lending to, or investing in, companies
that operate in industries with higher perceived environmental exposure; and

◾ we  may  be  less  able  to  take  advantage  of  significant  business  opportunities  and  to  react  to  changes  in  market  or  industry

conditions than our less levered competitors.

See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and

Capital Resources—Sources and uses of liquidity.”

CREDIT  RATING  AGENCIES  HAVE  RATED  OUR  DEBT  BELOW  INVESTMENT  GRADE,  WHICH  COULD
LIMIT OUR ACCESS TO CAPITAL AND HAVE AN ADVERSE EFFECT ON OUR BUSINESS AND FINANCIAL
CONDITION.

The ratings assigned to our debt securities by certain credit rating agencies (our “Debt Ratings”) are below investment
grade.  Our Debt Ratings could have adverse consequences for our business and future prospects and could cause the following:

◾ limitations on our ability to access debt markets, including for the purpose of refinancing our existing debt and replacing or

extending our Secured Credit Facility;

◾ less favorable terms and conditions on any refinancing arrangements, debt issuances or bank credit agreements, some of which

could require collateral and restrict, among other things, our ability to pay distributions or repurchase shares;

◾ increases to certain fees under our Secured Credit Facility and the interest rate under the indenture governing the 7.35% senior
notes  due  December  2041,  which  has  reached  the  maximum  rate  increase  of  2  percent  pursuant  to  the  indenture  due  to  the
downgrades of certain credit rating agencies;

◾ reduced willingness of current and prospective customers, suppliers and creditors to transact business with us;
◾ requirements from creditors, suppliers or customers for additional insurance, guarantees and collateral;
◾ limitations on our access to bank and third-party guarantees, surety bonds and letters of credit; and
◾ reductions to or eliminations of the level of credit suppliers and financial institutions may provide through payment terms or
intraday funding when dealing with us thereby increasing the need for higher levels of cash on hand, which would decrease
our ability to repay debt balances.

Our Debt Ratings have caused some of the effects listed above, and any further downgrades may cause or exacerbate,

any of the effects listed above and could have an adverse effect on our business and financial condition.

WORLDWIDE  FINANCIAL,  ECONOMIC  AND  POLITICAL  CONDITIONS  COULD  RESTRICT  OUR  ABILITY
TO ACCESS THE CAPITAL MARKETS, REDUCE OUR FLEXIBILITY TO REACT TO CHANGING ECONOMIC
AND BUSINESS CONDITIONS AND REDUCE DEMAND FOR OUR SERVICES.

Worldwide financial and economic conditions could restrict our ability to access the capital markets at a time when we
would like, or need, to access such markets, which could have an impact on our flexibility to react to changing economic and
business  conditions.   Worldwide  economic  conditions  have  in  the  past  impacted,  and  could  in  the  future  impact,  the  lenders
participating  in  our  credit  facilities  and  our  customers,  causing  them  to  fail  to  meet  their  obligations  to  us.    If  economic
conditions  preclude  or  limit  financing  from  banking  institutions  participating  in  our  credit  facilities,  we  may  not  be  able  to
obtain similar financing from other institutions.  A slowdown in economic activity could further reduce worldwide demand for
energy  and  extend  or  worsen  the  recovery  from  low  oil  and  natural  gas  prices.    These  potential  developments,  or  market
perceptions  concerning  these  and  related  issues,  could  adversely  affect  our  financial  position,  results  of  operations  or  cash
flows.  In addition, turmoil and hostilities in the Middle East, Ukraine, North Africa and other geographic areas and countries
present  incremental  risk.    An  extended  period  of  negative  outlook  for  the  world  economy  could  further  reduce  the  overall
demand for oil and natural gas and for our services.  A further decline in oil and natural gas prices or an extension of the current
low oil and natural gas prices could reduce demand for our drilling services and have an adverse effect on our financial position,
results of operations or cash flows.

RISKS RELATED TO LAWS, REGULATIONS AND GOVERNMENTAL COMPLIANCE

IMPACT OF INCREASINGLY STRINGENT ENVIRONMENTAL AND SAFETY LAWS AND OUR COMPLIANCE
WITH OR BREACH OF SUCH LAWS CAN BE COSTLY, EXPOSE US TO LIABILITY AND COULD LIMIT OUR
OPERATIONS.

Our  business  is  affected  by  laws  and  regulations  relating  to  the  energy  industry  and  the  environment  and  safety,
including international conventions and treaties, and regional, national, state, and local laws and regulations.  Our business also
depends  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,  delay  or
impose  additional  compliance  costs  and  obligations  related  to  the  exploration  and  development  drilling  for  oil  and  gas.
  Offshore  drilling  in  certain  areas  has  been  curtailed  and,  in  certain  cases,  prohibited  because  of  environmental  or  safety
concerns.    In  addition,  compliance  with  environmental  and  safety  laws,  regulations  and  standards,  where  applicable,  may
require us to make significant capital expenditures, such as the installation of costly equipment or implementation of operational
changes, and may affect the resale values or useful lives of our rigs.  We may also incur additional costs in order to comply with
other  existing  and  future  regulatory  obligations  or  industry  standards,  including,  but  not  limited  to,  costs  relating  to  air
emissions,  including  greenhouse  gases,  the  management  of  ballast  waters,  maintenance  and  inspection,  development  and
implementation of emergency procedures and maintenance of insurance coverage or other financial assurance of our ability to
address pollution incidents.  In the last decade, enhanced governmental safety and environmental requirements applicable to our
operations  were  adopted  by  U.S.  federal  agencies  for  drilling  in  the  U.S.  Gulf  of  Mexico.    These  requirements  have  caused
increased compliance costs and may in the future increase the risk of environmental or safety enforcement cases and litigation
and  cause  operators  to  have  difficulties  obtaining  drilling  permits  in  the  U.S.  Gulf  of  Mexico.    In  addition,  the  oil  and  gas
industry has adopted equipment and operating standards, such as the American Petroleum Institute Standard 53, related to the
installation  and  testing  of  well  control  equipment.   A  failure  to  comply  with  applicable  laws  and  regulations  may  result  in
administrative  and  civil  penalties,  criminal  sanctions  or  the  suspension  or  termination  of  our  operations.    Additionally,  our
customers  may  elect  to  voluntarily  comply  with  any  non-mandatory  laws,  regulations  or  other  standards.   Any  such  safety,
environmental  and  other  regulatory  restrictions  or  standards,  including  voluntary  customer  compliance  with  respect  thereto,
could  decrease,  disrupt  or  delay  operations,  decrease  demand  for  offshore  drilling  services,  increase  operating  costs  and
compliance costs or penalties, increase out-of-service time, decrease dayrates, or reduce the area of operations for drilling rigs
in  the  U.S.  and  non-U.S.  offshore  areas.   Any  such  effects  could  have  an  adverse  effect  on  our  financial  position,  results  of
operations or cash flows.

To the extent new laws are enacted, existing laws are changed or other governmental actions are taken that prohibit or
restrict offshore drilling or impose additional environmental protection and safety requirements that result in increased costs to
the oil and gas industry, in general, or the offshore drilling industry, in particular, our business or prospects could be materially
adversely affected.  The operation of our drilling rigs will require certain governmental approvals, some of which may involve
public hearings and costly undertakings on our part.  We may not obtain such approvals or such approvals may not be obtained
in a timely manner.  If we fail to timely secure the necessary governmental approvals or permits, our customers may have the
right to terminate or seek to renegotiate their drilling contracts to our detriment.  The amendment or modification of existing
laws and regulations or the adoption of new laws and regulations curtailing or further regulating exploratory or development
drilling or production of oil and gas and compliance with any such new or amended legislation or regulations could have an
adverse effect on our business or on our financial position, results of operations or cash flows.

As  a  contract  driller  with  operations  in  certain  offshore  areas,  we  may  be  liable  for  damages  and  costs  incurred  in
connection with oil spills or disposal of wastes related to those operations, and we may also be subject to significant fines and
other liabilities in connection with spills.  For example, an oil spill could result in significant liability, including fines, penalties
and criminal liability and remediation, restoration or compensation costs for environmental or natural resource damages, as well
as third-party damages, to the extent that the contractual indemnification provisions in our drilling contracts are not enforceable
or  otherwise  sufficient,  or  if  our  customers  are  unwilling  or  unable  to  contractually  indemnify  us  against  these  risks.
 Additionally, we may not be able to obtain such indemnities in our future drilling contracts, and our customers may not have
the financial capability to fulfill their contractual obligations to us.  Also, these indemnities may be held to be unenforceable in
certain jurisdictions, as a result of public policy or for other reasons.  Environmental and safety laws and regulations protecting
the environment have become increasingly stringent and may in some cases impose strict liability on facility or vessel owners or
operators, rendering a person liable for environmental damage without regard to negligence.  These 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.  The application of these requirements or the adoption of new requirements or measures
could have an adverse effect on our financial position, results of operations or cash flows.

REGULATORY AND VARIOUS OTHER RISKS, INCLUDING LITIGATION, ASSOCIATED WITH GREENHOUSE
GASES,  OTHER  EMISSIONS  AND  CLIMATE  CHANGE  COULD  HAVE  AN  ADVERSE  IMPACT  ON  OUR
BUSINESS AND DEMAND FOR OUR SERVICES.

Scientific studies have suggested that emissions of certain gases, including greenhouse gases, such as carbon dioxide
and methane, contribute to warming of the earth’s atmosphere and other climatic changes.  In response to such studies, the issue
of climate change and the effect of greenhouse gas emissions, in particular emissions from the fossil fuel industry, has attracted
and continues to attract considerable political and social attention worldwide.  The attention to climate change has led, and we
expect  it  to  continue  to  lead,  to  additional  regulations  designed  to  reduce  greenhouse  gas  emissions  domestically  and
internationally.  In August 2022, for example, the U.S. enacted the Inflation Reduction Act of 2022, which contains hundreds of
billions  of  dollars  in  incentives  for  the  development  of  renewable  energy,  clean  hydrogen,  clean  fuels,  electric  vehicles  and
supporting infrastructure and carbon capture and sequestration, amongst other provisions.  Such attention could also result in
other adverse impacts for the oil and gas industry, including further restrictions or bans

- 16 -

Table of Contents

imposed by lawmakers, lawsuits by governments or third-parties seeking recoveries for damages resulting from the combustion
of  fuels  that  may  contribute  to  climate  change  effects,  decreased  demand  for  goods  or  services  that  produce  significant
greenhouse gas emissions, or reduced interest from investors if they elect in the future to shift some or all of their investments to
non-fossil fuel related sectors.  To the extent financial markets view climate change and greenhouse emissions as a financial
risk, this could negatively impact our cost of or access to capital.  Because our business depends on the level of activity in the
oil and gas industry, existing or future laws, regulations, treaties or international agreements related to greenhouse gases and
climate change, or related political, litigation or financial risks, including incentives to conserve energy or use alternative energy
sources, could have a negative impact on our business if such laws, regulations, treaties or international agreements reduce the
worldwide demand for oil and gas or limit drilling opportunities.  In addition, such laws, regulations, treaties or international
agreements or related risks could result in increased compliance costs or additional operating restrictions, which may have an
adverse effect on our business.  Further, some experts believe global climate change could increase the frequency and severity
of extreme weather conditions, the impacts of which could interfere with our operations, cause damage to our equipment as well
as cause other financial and operational impacts, including those that could result from any impact of such conditions on our
customers.

We could also face increased climate-related litigation with respect to our operations both in the U.S. and around the
world.  Governmental and other entities in various U.S. states, such as California and New York, have filed lawsuits against
coal, gas oil and petroleum companies.  These suits allege damages as a result of climate change, and the plaintiffs are seeking
unspecified damages and abatement under various tort theories.  Similar lawsuits may be filed in other jurisdictions both in the
U.S. and globally.  Though we are not currently a party to any such lawsuit, these suits present a high degree of uncertainty
regarding the extent to which energy companies, including offshore drillers, face an increased risk of liability stemming from
climate change, which risk would also adversely impact the oil and gas industry and impact demand for our services.

ANY  RESTRICTIONS  ON  OIL  AND  NATURAL  GAS  OPERATIONS  ON  THE  U.S.  OUTER  CONTINENTAL
SHELF  (“OCS”)  COULD  HAVE  AN  ADVERSE  IMPACT  ON  OUR  BUSINESS  AND  DEMAND  FOR  OUR
SERVICES.

The U.S. Department of the Interior (“DOI”) administers the submerged lands, subsoil, and seabed, lying between the
seaward extent of the states’ jurisdiction and the seaward extent of federal jurisdiction, and the U.S. government has the power
to limit oil and gas activities on this area, known as the OCS.  Under the Outer Continental Shelf Lands Act, as amended, the
U.S.  Bureau  of  Ocean  Energy  management  (“BOEM”)  within  the  DOI  must  prepare  and  maintain  forward-looking  five-year
plans—referred to as national programs or five-year programs—to schedule proposed oil and gas lease sales on the OCS.  On
July 1, 2022, BOEM announced the availability of the Proposed Program for the 2023-2028 timeframe for public comments.
 The Proposed Program includes no more than ten potential lease sales in the U.S. Gulf of Mexico.  Inclusion of an area in the
Proposed Program is not a final indication that it will be included in the approved 2023-2028 National OCS Program or offered
in a lease sale.  In addition, the U.S. previously placed a moratorium on new oil and natural gas leases on federal lands and
waters, including the federal OCS.  Future actions taken by the U.S. to limit the availability of new oil and gas leases on the
OSC would adversely impact the offshore oil and gas industry and impact demand for our services.

THE GLOBAL NATURE OF OUR OPERATIONS INVOLVES ADDITIONAL RISKS.

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

including risks of:

◾ terrorist acts, war, piracy and civil unrest;
◾ seizure, expropriation or nationalization of our equipment;
◾ expropriation or nationalization of our customers’ property;
◾ repudiation or nationalization of contracts;
◾ imposition of trade or immigration barriers;
◾ import-export quotas;
◾ wage and price controls;
◾ changes in law and regulatory requirements, including changes in interpretation and enforcement;
◾ involvement in judicial proceedings in unfavorable jurisdictions;
◾ damage to our equipment or violence directed at our employees, including kidnappings;
◾ complications associated with supplying, repairing and replacing equipment in remote locations;
◾ the inability to move income or capital; and
◾ currency exchange fluctuations and currency exchange restrictions, including exchange or similar controls that may limit our

ability to convert local currency into U.S. dollars and transfer funds out of a local jurisdiction.

Our  non-U.S.  contract  drilling  operations  are  subject  to  various  laws  and  regulations  related  to  economic  and  trade
sanctions in certain countries in which we operate, including laws and regulations relating to the import and export, equipment
and  operation  of  drilling  units,  currency  conversions  and  repatriation,  oil  and  gas  exploration  and  development,  taxation  and
social  contributions  of  offshore  earnings  and  earnings  of  expatriate  personnel.    We  are  also  subject  to  the  U.S.  Treasury
Department’s  Office  of  Foreign  Assets  Control  (“OFAC”)  and  other  U.S.  and  non-U.S.  laws  and  regulations  governing  our
international operations.  In addition, various state and municipal governments, universities and other investors have proposed
or  adopted  divestment  and  other  initiatives  regarding  investments  including,  with  respect  to  state  governments,  by  state
retirement systems in companies that do business with countries that have been designated as state sponsors of terrorism by the
U.S. State Department.  Failure to comply with applicable laws and regulations, including those relating to sanctions and export
restrictions, may subject us to criminal sanctions or civil remedies, including fines, denial of export privileges, injunctions or
seizures of assets.  Investors could view any potential violations of OFAC regulations negatively, which could adversely affect
our reputation and the market for our shares.

Table of Contents

Governments  in  some  countries  have  become  increasingly  active  in  regulating  and  controlling  the  ownership  of
concessions and companies holding concessions, the exploration for oil and gas and other aspects of the oil and gas industries in
their  countries,  including  local  content  requirements  for  participating  in  tenders  for  certain  drilling  contracts.    Many
governments favor or effectively require the awarding of drilling contracts to local contractors or require nonlocal contractors to
employ citizens of, or purchase supplies from, a particular jurisdiction or require use of a local agent.  In addition, government
action,  including  initiatives  by  OPEC,  may  continue  to  cause  oil  or  gas  price  volatility.    In  some  areas  of  the  world,  this
governmental activity has adversely affected the amount of exploration and development work by major energy companies and
may continue to do so.

The shipment of goods, services and technology across international borders subjects us to extensive trade laws and
regulations.  Our import and export activities are governed by unique customs and export control laws and regulations in each
of  the  countries  where  we  operate.    Moreover,  many  countries,  including  the  U.S.,  control  the  import  and  export  of  certain
goods, services and technology and impose related import and export recordkeeping and reporting obligations.  Governments
also  may  impose  economic  sanctions  against  certain  countries,  persons  and  other  entities  that  may  restrict  or  prohibit
transactions involving such countries, persons and entities, and we are also subject to the U.S. anti-boycott laws.

The  laws  and  regulations  concerning  import  and  export  activity,  recordkeeping  and  reporting,  import  and  export
control and economic sanctions are complex and constantly changing.  These laws and regulations may be enacted, amended,
enforced  or  interpreted  in  a  manner  materially  impacting  our  operations.    Ongoing  economic  challenges  may  increase  some
governments’ efforts to enact, enforce, amend or interpret laws and regulations as a method to increase revenue.  Shipments can
be delayed and denied import or export for a variety of reasons, some of which are outside our control and some of which may
result from failure to comply with existing legal and regulatory regimes.  Shipping delays or denials could cause unscheduled
operational downtime.

Our  ability  to  operate  worldwide  depends  on  our  ability  to  obtain  the  necessary  visas  and  work  permits  for  our
personnel to travel in and out of, and to work in, the jurisdictions in which we operate.  Governmental actions in some of the
jurisdictions  in  which  we  operate  may  make  it  difficult  for  us  to  move  our  personnel  in  and  out  of  these  jurisdictions  by
delaying or withholding the approval of these permits.  If we are not able to obtain visas and work permits for the employees we
need to conduct our operations on a timely basis, we might not be able to perform our obligations under our drilling contracts,
which could allow our customers to cancel the contracts.  If our customers cancel some of our drilling contracts, and we are
unable to secure new drilling contracts on a timely basis and on substantially similar terms, it could have a material adverse
effect on our business and on our financial position, results of operations or cash flows.

FAILURE  TO  COMPLY  WITH  ANTI-BRIBERY  STATUTES,  SUCH  AS  THE  U.S.  FOREIGN  CORRUPT
PRACTICES  ACT  AND  THE  U.K.  BRIBERY  ACT  2010,  COULD  RESULT  IN  FINES,  CRIMINAL  PENALTIES,
DRILLING CONTRACT TERMINATIONS AND AN ADVERSE EFFECT ON OUR BUSINESS.

The U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act 2010 (“Bribery Act”) and similar anti-bribery
laws  in  other  jurisdictions,  generally  prohibit  companies  and  their  intermediaries  from  making  improper  payments  for  the
purpose of obtaining or retaining business.  We operate in many parts of the world that have experienced corruption to some
degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices.  If
we  are  found  to  be  liable  for  violations  under  the  FCPA,  the  Bribery  Act  or  other  similar  laws,  either  due  to  our  acts  or
omissions or due to the acts or omissions of others, including our partners in our various joint ventures and of the current or
former officers, directors or employees of any companies we have acquired, we could suffer from civil and criminal penalties or
other sanctions, which could have a material adverse effect on our business or our financial position, results of operations or
cash flows.  In addition, investors could negatively view potential violations, inquiries or allegations of misconduct under the
FCPA, the Bribery Act or similar laws, which could adversely affect our reputation and the market for our shares.

We could also face fines, sanctions and other penalties from authorities in relevant jurisdictions, including prohibition
of  our  participating  in  or  curtailment  of  business  operations  in  those  jurisdictions  and  the  seizure  of  rigs  or  other  assets.
 Additionally,  our  business  and  results  of  operations  could  be  adversely  affected  as  a  result  of  claims  by  customers,  agents,
shareholders,  debt  holders,  other  interest  holders,  current  or  former  employees  or  other  constituents  of  our  company  who,  in
connection  with  alleged  or  actual  noncompliance  with  antibribery  and  related  laws,  may  seek  to  impose  penalties,  seek
remedies, terminate drilling contracts or take other actions adverse to our interests.  Our business and results of operations may
be  adversely  affected  if  we  are  required  to  dedicate  significant  time  and  resources  to  investigate  and  resolve  allegations  of
misconduct,  regardless  of  the  merit  of  such  allegations.    Further,  disclosure  of  the  subject  matter  of  any  investigation  could
adversely affect our reputation and our ability to obtain new business with potential customers, to retain existing business with
our current customers, to attract and retain employees and to access the capital markets.

WE ARE SUBJECT TO INVESTIGATIONS AND LITIGATION THAT, IF NOT RESOLVED IN OUR FAVOR AND
NOT SUFFICIENTLY INSURED AGAINST, COULD HAVE A MATERIAL ADVERSE EFFECT ON US.

We are subject to a variety of disputes, investigations and litigation.  Certain of our subsidiaries are subject to and have
been  involved  in  litigation  with  certain  of  our  customers  and  other  constituents.    Certain  of  our  subsidiaries  are  named  as
defendants in numerous lawsuits alleging personal grievances or injury, including as a result of exposure to asbestos or toxic
fumes  or  resulting  from  other  occupational  diseases,  such  as  silicosis,  and  various  other  medical  issues  that  can  remain
undiscovered for a considerable amount of time.  Some of these subsidiaries that have been put on notice of potential liabilities
have  no  assets.    Certain  subsidiaries  are  subject  to  litigation  relating  to  environmental  damage.    Our  patent  for  dual-activity
technology has been successfully challenged in certain jurisdictions.  We are also subject to a number of significant tax disputes.
 We cannot predict the outcome of these investigations and cases or the potential costs

to resolve them.  Insurance may not be applicable or sufficient in all cases, insurers may not remain solvent and policies may
not be located.  Suits against non-asset-owning subsidiaries have and may in the future give rise to alter ego or successor-in-
interest claims against us and our asset-owning subsidiaries to the extent a subsidiary is unable to pay a claim or insurance is not
available or sufficient to cover the claims.  To the extent that one or more pending or future investigations or litigation matters is
not resolved in our favor and is not covered by insurance, which could have a material adverse effect on our financial position,
results of operations or cash flows.

WE  ARE  SUBJECT  TO  CYBERSECURITY  RISKS  AND  THREATS  AS  WELL  AS  INCREASING  REGULATION
OF DATA PRIVACY AND SECURITY.

We depend on data and digital technologies to conduct our offshore and onshore operations, to collect payments from
customers and to pay vendors and employees.  Our data protection measures and measures taken by our customers and vendors
may not prevent unauthorized access of information technology systems, and when such unauthorized access occurs, we, our
customers or vendors may not detect the incident in time to prevent harm or damage.  Threats to our information technology
systems,  and  the  systems  of  our  customers  and  vendors,  associated  with  cybersecurity  risks  and  cyber-incidents  or  attacks
continue to grow.  Such threats may derive from human error, fraud or malice, social engineering on the part of employees or
third  parties,  or  may  result  from  accidental  technological  failure.    In  addition,  breaches  to  our  systems  and  systems  of  our
customers and vendors could go unnoticed for some period of time.  Risks associated with these threats include disruptions of
certain systems on our rigs; other impairments of our ability to conduct our operations; loss or ransom of intellectual property,
proprietary  information,  personal  identifiable  information  or  customer  and  vendor  data;  disruption  of  our  customers’  and
vendors’  operations;  misappropriation  of  assets;  loss  or  damage  to  our  customer  and  vendor  data  delivery  systems;  and
increased costs to prevent, respond to or mitigate cybersecurity events.  A breach could also originate from, or compromise, our
customers’  and  vendors’  or  other  third-party  networks  outside  of  our  control.   A  breach  may  also  result  in  legal  claims  or
proceedings against us by our shareholders, employees, customers, vendors and governmental authorities, both U.S. and non-
U.S.  If such a cyber-incident were to occur, it could have a material adverse effect on our business or on our financial position,
results of operations or cash flows.

In addition, governing data privacy and the unauthorized disclosure of personal data and confidential information pose
increasingly  complex  compliance  challenges  and  potential  to  elevate  our  costs  under  various  laws  and  regulations,  including
(a) the European Union General Data Protection Regulation, the Data Protection Act, as revised, of the Cayman Islands, (b) the
General Data Protection Law of Brazil and (c) the California Consumer Privacy Act, as well as (d) the amended Swiss Data
Protection Act, which will enter into force in September 2023,.  Any failure by us to comply with these laws and regulations,
including  as  a  result  of  a  security  or  privacy  breach,  could  result  in  significant  penalties,  litigation  and  liabilities  for  us.
 Additionally, if we acquire a company that has violated or is not in compliance with applicable data protection laws, we may
incur significant liabilities and penalties as a result.

ACTS  OF  TERRORISM,  PIRACY  AND  POLITICAL  AND  SOCIAL  UNREST  COULD  AFFECT  THE  MARKETS
FOR DRILLING SERVICES.

Acts of terrorism and social unrest, brought about by world political events or otherwise, have caused instability in the
world’s financial and insurance markets in the past and may occur in the future.  Such acts could be directed against companies
such as ours.  In addition, acts of terrorism, piracy and social unrest could lead to increased volatility in prices for crude oil and
natural  gas  and  could  affect  the  markets  for  drilling  services.    Insurance  premiums  could  increase  and  coverage  may  be
unavailable in the future.  Government regulations may effectively preclude us from engaging in business activities in certain
countries.  These regulations could be amended to cover countries where we currently operate or where we may wish to operate
in the future.  Our drilling contracts do not generally provide indemnification against loss of capital assets or loss of revenues
resulting from acts of terrorism, piracy or political or social unrest.  We have limited insurance for our assets providing coverage
for  physical  damage  losses  resulting  from  certain  risks,  such  as  terrorist  acts,  piracy,  vandalism,  sabotage,  civil  unrest,
expropriation and acts of war, and we do not carry insurance for loss of revenues resulting from such risks.

RISKS RELATED TO TAXES

A CHANGE IN TAX LAWS, TREATIES OR REGULATIONS, OR THEIR INTERPRETATION, OF ANY COUNTRY
IN  WHICH  WE  HAVE  OPERATIONS,  ARE  INCORPORATED  OR  ARE  RESIDENT  COULD  RESULT  IN  A
HIGHER  EFFECTIVE  TAX  RATE  ON  OUR  CONSOLIDATED  EARNINGS  AND  INCREASE  OUR  CASH  TAX
PAYMENTS.

We are subject to changes in applicable tax laws, treaties or regulations in the jurisdictions in which we operate and
earn income, and such changes could include laws or policies directed toward companies organized in jurisdictions with low tax
rates with the intent to increase the tax burden.  The Organization for Economic Co-operation and Development, for example,
issued  its  action  plan  of  tax  reform  measures  that  called  for  member  states  to  take  action  to  prevent  base  erosion  and  profit
shifting.  Some of these measures impact transfer pricing, requirements to qualify for tax treaty benefits, and the definition of
permanent establishments depending on each jurisdiction’s adoption and interpretation of such proposals.  Respective countries,
including  Switzerland,  have  adopted  various  measures  into  their  own  tax  laws.    In  addition,  the  European  Union  has  issued
Anti-Tax  Avoidance  Directives  and  proposed  directives  that  required  or  require  member  states  to  adopt  specific  tax  reform
measures, some of which relate to a 15 percent minimum tax.  Other tax jurisdictions in which we operate have expressed an
intent to implement similar measures.  Any material change to tax laws, treaties, regulations or policies, their interpretation or
application, or the adoption of new interpretations of existing laws and rulings, in any of the jurisdictions in which we operate,
are incorporated or resident, could result in a higher effective tax rate on our worldwide earnings and such change could have a
significant adverse effect on our financial position, results of operations or cash flows.

A  LOSS  OF  A  MAJOR  TAX  DISPUTE  OR  A  SUCCESSFUL  TAX  CHALLENGE  TO  OUR  OPERATING
STRUCTURE,  INTERCOMPANY  PRICING  POLICIES  OR  THE  TAXABLE  PRESENCE  OF  OUR  KEY
SUBSIDIARIES  IN  CERTAIN  COUNTRIES  COULD  RESULT  IN  A  HIGHER  EFFECTIVE  TAX  RATE  ON  OUR
CONSOLIDATED EARNINGS AND INCREASE OUR CASH TAX PAYMENTS.

We are subject to tax laws, treaties and regulations in the countries in which we operate and earn income.  Our income
taxes are based on the applicable tax laws and tax rates in effect in the countries in which we operate and earn income as well as
upon  our  operating  structures  in  these  countries.    Our  income  tax  returns  are  subject  to  review  and  examination  in  these
jurisdictions, and we do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed
upon challenge by a tax authority.  If any tax authority successfully challenges our operational structure, intercompany pricing
policies or the taxable presence of our key subsidiaries in certain countries; or if the terms of certain income tax treaties are
interpreted in a manner that is adverse to our structure; or if we lose a material tax dispute in any country, our effective tax rate
on our worldwide earnings could increase substantially and our earnings and cash flows from operations could be materially
adversely affected.  For example, we believe that neither we nor our non-U.S. subsidiaries, other than those that report a U.S.
trade or business or a U.S. permanent establishment, were or are engaged in a trade or business in the U.S. or, if applicable,
maintained or maintain a permanent establishment in the U.S.  The determination of the aforementioned, among other things,
involves considerable uncertainty.  If the U.S. Internal Revenue Service were to disagree, then we could be subject to additional
U.S. corporate income and branch profits taxes on the portion of our earnings effectively connected to such U.S. business or, if
applicable, attributable to such U.S. permanent establishment during the period in which this was considered to have occurred.
 If this occurs, our effective tax rate on worldwide earnings for that period could increase substantially, we could be subject to
assessments in previously filed returns that remain open to audit and our earnings and cash flows from operations for that period
could be adversely affected.

RISKS RELATED TO OUR JURISDICTION OF ORGANIZATION AND GOVERNING DOCUMENTS

AS A SWISS CORPORATION, OUR FLEXIBILITY MAY BE LIMITED WITH RESPECT TO CERTAIN ASPECTS
OF CAPITAL MANAGEMENT AND SWIFT IMPLEMENTATION OF CERTAIN INITIATIVES OR STRATEGIES.

Under Swiss law, our shareholders may approve an authorized share capital that allows the board of directors to issue
new shares without additional shareholder approval within a period of up to two years and for up to a maximum of 50 percent of
a company’s issued share capital.  The authorized share capital approved by our shareholders at the May 2022 annual general
meeting  will  expire  on  May  12,  2024.    Our  currently  available  authorized  share  capital  is  approximately  13.5  percent  of  our
issued share capital as of February 14, 2023.  Accordingly, shareholders at our annual general meeting in May 2023 may be
requested to approve a renewal and an increase in authorized share capital.  Subject to certain exceptions, Swiss law also grants
preemptive  rights  to  existing  shareholders  to  subscribe  for  new  issuances  of  shares.    Further,  Swiss  law  does  not  provide  as
much flexibility in the various terms that can attach to different classes of shares as the laws of some other jurisdictions.  Swiss
law  also  reserves  for  shareholder  approval  certain  corporate  actions,  such  as  approval  of  dividends,  over  which  a  board  of
directors would have authority in some other jurisdictions.  These Swiss law requirements relating to our capital management
may limit our flexibility to swiftly implement certain initiatives or strategies, and situations may arise where greater flexibility
would have provided substantial benefits to our shareholders.

We are required, from time to time, to evaluate the carrying amount of our investments in affiliates, as presented on our
Swiss standalone balance sheet.  If we determine that the carrying amount of any such investment exceeds its fair value, we may
conclude that such investment is impaired.  Any recognized loss associated with such a non-cash impairment could result in our
net assets no longer covering our statutory share capital and statutory capital reserves.  Under Swiss law, if our net assets cover
less than 50 percent of our statutory share capital and the non-distributable part of the statutory capital and profit reserves, the
board  of  directors  must  take  appropriate  measures  or,  to  the  extent  such  measures  fall  within  the  competence  of  the  general
meeting  of  shareholders,  convene  a  general  meeting  of  shareholders,  and  propose  measures  to  remedy  such  a  capital  loss.
 Appropriate measures depend on the relevant circumstances and the magnitude of the recognized loss and may include seeking
shareholder  approval  for  offsetting  the  aggregate  loss,  or  a  portion  thereof,  with  our  statutory  capital  reserves,  including
qualifying additional paid-in capital otherwise available for distributions to shareholders, or raising new equity.  Depending on
the circumstances, we may also need to use qualifying additional paid-in capital available for distributions in order to reduce
our  accumulated  net  loss  and  such  use  might  reduce  our  ability  to  make  distributions  without  subjecting  our  shareholders  to
Swiss withholding tax.

Distributions  to  shareholders  in  the  form  of  a  par  value  reduction  and  dividend  distributions  out  of  qualifying
additional  paid-in  capital  are  currently  not  subject  to  the  35  percent  Swiss  federal  withholding  tax.    However,  the  Swiss
withholding  tax  rules  could  be  changed  in  the  future,  and  any  such  change  may  adversely  affect  us  or  our  shareholders.    In
addition, over the long term, the amount of par value available for us to use for par value reductions or the amount of qualifying
additional paid-in capital available for us to pay out as distributions is limited.  If we are unable to make a distribution through a
reduction in par value, or out of qualifying additional paid-in capital as shown on Transocean Ltd.’s standalone Swiss statutory
financial statements, we may not be able to make distributions without subjecting our shareholders to Swiss withholding taxes.

Under  Swiss  tax  law,  repurchases  of  shares  for  the  purposes  of  capital  reduction  are  treated  as  a  partial  liquidation
subject to a 35 percent Swiss withholding tax based on the difference between the repurchase price and the related amount of
par  value  and  the  related  amount  of  qualifying  additional  paid-in  capital,  if  any.   At  our  2009  annual  general  meeting,  our
shareholders  approved  the  repurchase  of  up  to  CHF  3.50  billion  of  our  shares  for  cancellation  under  the  share  repurchase
program.    If  we  repurchase  shares,  we  expect  to  use  an  alternative  procedure  pursuant  to  which  we  repurchase  shares  via  a
“virtual second trading line” from market players, such as banks and

- 20 -

Table of Contents

institutional investors, who are generally entitled to receive a full refund of the Swiss withholding tax.  The use of such “virtual
second trading line” with respect to share repurchase programs is subject to the approval of the competent Swiss tax and other
authorities.  We may not be able to repurchase as many shares as we would like to repurchase for purposes of capital reduction
on the “virtual second trading line” without subjecting the selling shareholders to Swiss withholding taxes.

WE ARE SUBJECT TO ANTI-TAKEOVER PROVISIONS.

Our articles of association and Swiss law contain provisions that could prevent or delay an acquisition of the company
by means of a tender offer, a proxy contest or otherwise.  Actions taken under such provisions may adversely affect prevailing
market prices for our shares, and could, among other things:

◾ provide that the board of directors is authorized, subject to obtaining shareholder approval every two years, at any time during
a  maximum  two-year  period,  which  under  our  current  authorized  share  capital  will  expire  on  May  12,  2024,  to  issue  a
specified number of shares, which under our current authorized share capital is approximately 13.5 percent of the share capital
registered  in  the  commercial  register  as  of  February  14,  2023,  and  to  limit  or  withdraw  the  preemptive  rights  of  existing
shareholders in various circumstances;

◾ provide  for  a  conditional  share  capital  that  authorizes  the  issuance  of  additional  shares  up  to  a  maximum  amount  of
approximately  17.9  percent  of  the  share  capital  registered  in  the  commercial  register  as  of  February  14,  2023,  without
obtaining additional shareholder approval through: (1) the exercise of conversion, exchange, option, warrant or similar rights
for the subscription of shares granted in connection with bonds, options, warrants or other securities newly or already issued in
national or international capital markets or new or already existing contractual obligations by or of any of our subsidiaries; or
(2) in connection with the issuance of shares, options or other share-based awards;

◾ provide that any shareholder who wishes to propose any business or to nominate a person or persons for election as director at

any annual meeting may only do so if we are given advance notice;

◾ provide that directors can be removed from office only by the affirmative vote of the holders of at least 66 2/3 percent of the

shares entitled to vote;

◾ provide  that  a  merger  or  demerger  transaction  requires  the  affirmative  vote  of  the  holders  of  at  least  66  2/3  percent  of  the
shares represented at the meeting and provide for the possibility of a so-called cash-out or squeeze-out merger if the acquirer
controls 90 percent of the outstanding shares entitled to vote at the meeting;

◾ provide  that  any  action  required  or  permitted  to  be  taken  by  the  holders  of  shares  must  be  taken  at  a  duly  called  annual  or

extraordinary general meeting of shareholders;

◾ limit the ability of our shareholders to amend or repeal some provisions of our articles of association; and
◾ limit transactions between us and an “interested shareholder,” which is generally defined as a shareholder that, together with its
affiliates and associates, beneficially, directly or indirectly, owns 15 percent or more of our shares entitled to vote at a general
meeting.

ITEM 1B.UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

The description of our property included under “Item 1. Business” is incorporated by reference herein.  We maintain
offices, land bases and other facilities worldwide, most of which we lease, including principal executive offices in Steinhausen,
Switzerland, and corporate offices in Houston, Texas, and the Cayman Islands.  Our remaining offices and bases are located in
various countries in North America, Europe, South America, Asia and Africa.

ITEM 3. LEGAL PROCEEDINGS

We  have  certain  actions,  claims  and  other  matters  pending  as  discussed  and  reported  in  “Part  II.  Item  8.  Financial
Statements  and  Supplementary  Data—Notes 
to  Consolidated  Financial  Statements—Note  12—Commitments  and
Contingencies” and “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
—Other  Matters—Regulatory  Matters”  in  this  annual  report  on  Form  10-K.    We  are  also  involved  in  various  tax  matters  as
described  in  “Part  II.  Item  8.  Financial  Statements  and  Supplementary  Data—Notes  to  Consolidated  Financial  Statements—
Note 10—Income Taxes” and in “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of
Operations—Other Matters—Tax matters” in this annual report on Form 10-K.  All such actions, claims, tax and other matters
disclosed therein are incorporated herein by reference.

As of December 31, 2022, we were involved in a number of other lawsuits, regulatory matters, disputes and claims,
asserted  and  unasserted,  all  of  which  have  arisen  in  the  ordinary  course  of  our  business  and  for  which  we  do  not  expect  the
liability, if any, to have a material adverse effect on our consolidated financial position, results of operations or cash flows.  We
cannot  predict  with  certainty  the  outcome  or  effect  of  any  of  the  matters  referred  to  above  or  of  any  such  other  pending,
threatened or possible litigation or legal proceedings.  We can provide no assurance that our beliefs or expectations as to the
outcome  or  effect  of  any  lawsuit  or  claim  or  dispute  will  prove  correct,  and  the  eventual  outcome  of  these  matters  could
materially differ from management’s current estimates.

On December 17, 2021, Transocean Offshore Deepwater Drilling Inc., our wholly owned subsidiary, received a letter
from the U.S. Department of Justice (the “DOJ”) related to alleged violations by our subsidiary of its Clean Water Act (“CWA”)
National Pollutant Discharge Elimination System permit (“Permit”).  The alleged violations, involving seven of our drillships,
were identified by the U.S.

- 21 -

Table of Contents

Environmental Protection Agency (“EPA”) following an initial inspection in 2018 of our compliance with the Permit and the
CWA and relate to deficiencies with respect to records retention, reporting requirements, discharges, permit limits, inspections
and  maintenance,  and  the  submission  of  monitoring  reports.    In  connection  with  the  initial  EPA  inspection,  we  initiated
modifications to our Permit and CWA compliance processes and maintained a dialogue with the EPA regarding the design and
implementation  of  enhancements  to  these  processes.   At  the  DOJ’s  invitation,  in  an  effort  to  resolve  the  matter,  we  initiated
settlement discussions with the DOJ, which remain ongoing, and the enforcement action will likely result in our agreeing to take
or continue to take certain corrective actions to ensure current and future Permit and CWA compliance and to pay a monetary
penalty,  which  we  believe  at  this  time  would  be  immaterial.    We  do  not  believe  that  the  enforcement  action  would  have  a
material  adverse  effect  on  our  consolidated  financial  position,  results  of  operations  or  cash  flow.    If  our  current  expectations
relating to these costs prove to be inaccurate, future expenditures may exceed our accrued amounts.

In addition to the legal proceedings described above, we may from time to time identify other matters that we monitor
through our compliance program or in response to events arising generally within our industry and in the markets where we do
business.  We evaluate matters on a case by case basis, investigate allegations in accordance with our policies and cooperate
with applicable governmental authorities.  Through the process of monitoring and proactive investigation, we strive to ensure no
violation of our policies, Code of Integrity or law has occurred, or will occur; however, we can provide no assurance as to the
outcome of these matters.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER MATTERS

AND ISSUER PURCHASES OF EQUITY SECURITIES

MARKET FOR SHARES OF OUR COMMON EQUITY

Our shares are listed on the New York Stock Exchange under the ticker symbol “RIG.”  On February 14, 2023, we had

726,263,759 shares outstanding and 4,893 holders of record of our shares.

SHAREHOLDER MATTERS

Swiss tax consequences to our shareholders

Overview—The  tax  consequences  discussed  below  are  not  a  complete  analysis  or  listing  of  all  the  possible  tax
consequences that may be relevant to our shareholders.  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 is not 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, subject to certain exceptions.  See “—Swiss withholding tax on dividends
and similar distributions to shareholders.”

Swiss wealth tax—A non-Swiss holder is not 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 is not 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 are subject to cantonal, communal and federal income tax.

Swiss  withholding  tax  on  dividends  and  similar  distributions  to  shareholders—A  Swiss  withholding  tax  of
35 percent is due on dividends and similar distributions to our shareholders from us, regardless of the place of residency of the
shareholder, subject to the exceptions discussed under “—Exemption” 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.

Exemption—Distributions to shareholders in the form of a par value reduction or out of qualifying additional paid-in
capital for Swiss statutory purposes are exempt from Swiss withholding tax.  On December 31, 2022, the aggregate amount of
par value of our outstanding shares was CHF 72.2 million, equivalent to approximately $78.1 million, and the aggregate amount
of  qualifying  additional  paid-in  capital  of  our  outstanding  shares  was  CHF  14.0  billion,  equivalent  to  approximately
$15.1  billion.    Consequently,  we  expect  that  a  substantial  amount  of  any  potential  future  distributions  may  be  exempt  from
Swiss withholding tax.

Refund available to 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.

Refund  available  to  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.  Switzerland has entered into bilateral treaties for the avoidance of
double  taxation  with  respect  to  income  taxes  with  numerous  countries,  including  the  United  States  (“U.S.”),  whereby  under
certain circumstances all or part of the withholding tax may be refunded.  The procedures for claiming treaty refunds, and the
time frame required for obtaining a refund, may differ from country to country.

Refund available to 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 100 percent 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 the following: (a) beneficial ownership, (b) U.S. residency and (c) 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 Bern, Switzerland), not 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 above address or can be downloaded from the webpage of the Swiss federal tax administration.  Each form
must be completed 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.

Table of Contents

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.

Share repurchases

Shares repurchased for the purpose of capital reduction are treated as a partial liquidation subject to a 35 percent Swiss
withholding  tax  based  on  the  difference  between  the  repurchase  price  and  the  related  amount  of  par  value  and  the  related
amount of qualifying additional paid-in capital, if any.  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.
  However,  for  such  repurchased  shares,  the  portions  of  the  repurchase  price  that  are  attributable  to  the  par  value  and  the
qualifying additional paid-in capital for Swiss statutory reporting purposes are not subject to the Swiss withholding tax.

If we repurchase shares, we expect to use an alternative procedure pursuant to which we repurchase our shares via a
"virtual second trading line" from market players, such as banks and institutional investors, who are generally entitled to receive
a  full  refund  of  the  Swiss  withholding  tax.    The  use  of  such  “virtual  second  trading  line”  with  respect  to  share  repurchase
programs is subject to approval of the competent Swiss tax and other authorities.  We may not be able to repurchase as many
shares as we would like to repurchase for purposes of capital reduction on the “virtual second trading line” without subjecting
the selling shareholders to Swiss withholding taxes.  The repurchase of shares for purposes other than for cancellation, such as
to retain as treasury shares for use in connection with stock incentive plans, convertible debt or other instruments within certain
periods,  are  not  generally  subject  to  Swiss  withholding  tax.    In  addition,  in  December  2022,  the  U.S.  Department  of  the
Treasury  released  proposed  regulations  under  the  Inflation  Reduction  Act,  whereby  an  excise  tax  of  one  percent  would  be
imposed on stock repurchases in the event one of our U.S. subsidiaries funds the stock repurchase.

Under Swiss corporate law, the right of a company and its subsidiaries to repurchase and hold its own shares is limited.
 A company may repurchase its shares to the extent it has freely distributable reserves as shown on its Swiss statutory balance
sheet in the amount of the purchase price and if the aggregate par value of all shares held by the company as treasury shares
does not exceed 10 percent of the company’s share capital recorded in the Swiss Commercial Register, whereby for purposes of
determining  whether  the  10  percent  threshold  has  been  reached,  shares  repurchased  under  a  share  repurchase  program  for
cancellation purposes authorized by the company’s shareholders are disregarded.  As of February 14, 2023, Transocean Inc., our
wholly owned subsidiary, held as treasury shares 8.90 percent of our issued shares.  Our board of directors could, to the extent
freely  distributable  reserves  are  available,  authorize  the  repurchase  of  additional  shares  for  purposes  other  than  cancellation,
such as to retain treasury shares for use in satisfying our obligations in connection with incentive plans or other rights to acquire
our shares.  Based on the number of shares held as treasury shares as of February 14, 2023, 1.10 percent of our issued shares
could be repurchased for purposes of retention as additional treasury shares.  Although our board of directors has not approved
such a share repurchase program for the purpose of retaining repurchased shares as treasury shares, if it did so, any such shares
repurchased would be in addition to any shares repurchased under the currently approved program.

(a)

In  May  2009,  at  our  annual  general  meeting,  our  shareholders  approved  and  authorized  our  board  of  directors,  at  its  discretion,  to
repurchase for cancellation any amount of our shares for an aggregate purchase price of up to CHF 3.50 billion.  At December 31, 2022,
the authorization remaining under the share repurchase program was for the repurchase of our outstanding shares for an aggregate cost of
up to CHF 3.24 billion, equivalent to $3.51 billion.  The share repurchase program may be suspended or discontinued by our board of
directors  or  company  management,  as  applicable,  at  any  time.    See  “Item  7.  Management’s  Discussion  and  Analysis  of  Financial

BUSINESS

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,”
“we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas  wells.    As  of
February 14, 2023, we owned or had partial ownership interests in and operated 37 mobile offshore drilling units, consisting of
27  ultra-deepwater  floaters  and  10  harsh  environment  floaters.   Additionally,  as  of  February  14,  2023,  we  were  constructing
one ultra-deepwater drillship and held a noncontrolling ownership interest in a company that is constructing one ultra-deepwater
drillship.

We  provide,  as  our  primary  business,  contract  drilling  services  in  a  single  operating  segment,  which  involves
contracting  our  mobile  offshore  drilling  rigs,  related  equipment  and  work  crews  to  drill  oil  and  gas  wells.   We  specialize  in
technically  demanding  regions  of  the  global  offshore  drilling  business  with  a  particular  focus  on  ultra-deepwater  and  harsh
environment  drilling  services.    Our  drilling  fleet  is  one  of  the  most  versatile  fleets  in  the  world,  consisting  of  drillships  and
semisubmersible floaters used in support of offshore drilling activities and offshore support services on a worldwide basis.

We  perform  contract  drilling  services  by  deploying  our  high-specification  fleet  in  a  single,  global  market  that  is
geographically dispersed in oil and gas exploration and development areas throughout the world.  Although rigs can be moved
from one region to another, the cost of moving rigs and the availability of rig-moving vessels may cause the supply and demand
balance to fluctuate somewhat between regions.  Still, significant variations between regions do not tend to persist long term
because  of  rig  mobility.    The  location  of  our  rigs  and  the  allocation  of  resources  to  operate,  build  or  upgrade  our  rigs  are
determined by the activities and needs of our customers.

SIGNIFICANT EVENTS

Fleet  expansion—In  October  2022,  we  completed  the  construction  of  and  placed  into  service  the  ultra-deepwater
floater Deepwater Atlas.  In November 2022, we made a cash contribution of $15 million associated with our noncontrolling
ownership interest in Liquila Ventures Ltd. (together with its subsidiaries, “Liquila”), a Bermuda company formed to construct,
own and operate the newbuild ultra-deepwater drillship Deepwater Aquila.  See “—Liquidity and Capital Resources—Sources
and uses of liquidity” and “—Liquidity and Capital Resources—Drilling fleet.”

Secured  debt  issuance—In  January  2023,  we  issued  $525  million  aggregate  principal  amount  of  8.375%  senior
secured notes due February 2028 (the “8.375% Senior Secured Notes”), and we received $515 million aggregate cash proceeds,
net of issue costs.  In January 2023, we issued $1.175 billion aggregate principal amount of 8.75% senior secured notes due
February 2030 (the “8.75% Senior Secured Notes”), and we received $1.157 billion aggregate cash proceeds, net of issue costs.
 See “—Liquidity and Capital Resources—Sources and uses of liquidity.”

Debt  and  warrant  issuance—In  September  2022,  we  issued  $300  million  aggregate  principal  amount  of
4.625% senior guaranteed exchangeable bonds due September 2029 (the “4.625% Senior Guaranteed Exchangeable Bonds”) in
connection  with  (a)  the  issuance  for  aggregate  cash  proceeds  of  $188  million  and  (b)  the  exchanges  (the  “2022  Private
Exchange”) of certain of the 0.50% exchangeable senior bonds due January 2023 (the “0.50% Exchangeable Senior Bonds”)
and the 7.25% senior notes due November 2025 (the “7.25% Senior Notes”).  In connection with the 2022 Private Exchange,
we also issued 22.2 million warrants to purchase Transocean Ltd. shares.  See “—Liquidity and Capital Resources—Sources
and uses of liquidity.”

Shipyard Loans—In  June  2022,  we  borrowed  $349  million  under  one  of  two  credit  agreements  (each,  a  “Shipyard
Loan,” and together, the “Shipyard Loans”) and made a cash payment of $46 million to satisfy the final milestone payment due
upon delivery of Deepwater Atlas.  In December 2022, we borrowed $90 million under the second Shipyard Loan and made a
cash payment of $325 million to satisfy the final milestone payment due upon delivery of Deepwater Titan.  We recorded the
Shipyard  Loan  for  Deepwater  Atlas  and  Deepwater  Titan,  net  of  imputed  interest,  and  the  corresponding  non-cash  capital
additions  of  $300  million  and  $82  million,  respectively.    See  “—Liquidity  and  Capital  Resources—Sources  and  uses  of
liquidity” and “—Liquidity and Capital Resources—Drilling fleet.”

Early  debt  retirement—In  January  2023,  in  connection  with  the  issuance  of  the  8.75%  Senior  Secured  Notes,  we
made  an  aggregate  payment  of  $1.156  billion,  including  a  make-whole  premium,  to  redeem  the  remaining  outstanding
$311 million, $240 million, $250 million, and $336 million aggregate principal amount of the 5.875% senior secured notes due
January  2024  (the  “5.875%  Senior  Secured  Notes”),  the  7.75%  senior  secured  notes  due  October  2024  (the  “7.75%  Senior
Secured Notes”), the 6.25% senior secured notes

Table of Contents

due  December  2024  (the  “6.25%  Senior  Secured  Notes”)  and  the  6.125%  senior  secured  notes  due  August  2025  (the
“6.125% Senior Secured Notes”), respectively.

In January 2023, we made a cash payment of $121 million to redeem an equivalent aggregate principal amount of the
outstanding 5.375% senior secured notes due May 2023 (the “5.375% Senior Secured Notes”), and the trustee notified holders
of our intent to redeem the remaining outstanding $122 million aggregate principal amount of notes for an equivalent aggregate
cash payment, expected to be made on February 24, 2023.

In July 2022, we made an aggregate cash payment of $27 million to redeem an equivalent aggregate principal amount
of  the  then  outstanding  3.80%  senior  notes  due  October  2022  (the  “3.80%  Senior  Notes”).    In  January  2022,  we  made  an
aggregate cash payment of $18 million to redeem an equivalent aggregate principal amount of the 5.52% senior secured notes
due  May  2022  (the  “5.52%  Senior  Secured  Notes”).    See  “—Operating Results”  and  “—Liquidity  and  Capital  Resources—
Sources and uses of liquidity.”

Share issuance—In June 2021, we commenced an at-the-market equity offering program (the “ATM Program”).  In
the year ended December 31, 2022, we received aggregate cash proceeds of $263 million, net of issue costs, for the aggregate
sale of 61.0 million shares under the ATM Program.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.”

Secured credit facility amendment—In  July  2022,  we  amended  the  bank  credit  agreement  for  our  Secured  Credit
Facility (as amended from time to time, the “Secured Credit Facility”) to, among other things, extend the maturity date from
June 22, 2023 to June 22, 2025 and reduce the borrowing capacity from $1.33 billion to $774 million through June 22, 2023,
and thereafter, reduce the borrowing capacity to $600 million through June 22, 2025.  See “—Liquidity and Capital Resources
—Sources and uses of liquidity.”

OUTLOOK

Drilling market—Our  industry  outlook  is  positive  based  upon  several  fundamental  factors,  including  the  increased
global demand for hydrocarbons combined with a diminishing global supply, the latter being the result of the natural decline in
production of existing oil and gas fields compounded by the significant underinvestment in reserve replacement by oil and gas
producers, and additional constraints imposed on industry participants by the governments of oil and gas producing nations as
well  as  investors.    Additionally,  the  Russian  invasion  of  Ukraine  and  the  related  economic  sanctions  have  highlighted  the
criticality of energy reliability and security across Europe, the U.S. and elsewhere.  Due to these and other factors, oil prices
have increased materially over the past two years and even reached 10-year highs.

Although the price for both prompt and longer-dated barrels continues to exhibit volatility that reflects market concerns
about inflationary trends, economic recession and the potential for demand destruction, these commodity prices are currently,
and are expected to remain, at levels that are robustly supportive of investment in deepwater and harsh environment exploration
and development projects.  Additionally, rig attrition resulting from significantly reduced offshore contracting activity over the
last  several  years  has  resulted  in  a  much  smaller  global  fleet  of  floating  rigs  that  is  available  to  meet  customer  demands,
specifically  with  respect  to  the  highest  specification  drilling  units  required  by  many  of  our  customers  for  their  projects.
 Consequently, our outlook for the offshore drilling industry overall remains positive, particularly for high-specification drilling
assets, such as those we own and operate.

Our  customers  continue  to  show  interest  in  deepwater  and  harsh  environment  offshore  projects  as  evidenced  by  the
restarting of delayed projects and commencement of new drilling campaigns.  Licensing activity has also increased as energy
companies look to explore and develop new prospects.  This has resulted in more tendering activity during the last half of 2022
and into 2023.  Several multi-year tenders for work in Brazil, West Africa, Asia and Australia are expected to be awarded in the
first  nine  months  of  2023.   We  have  recently  observed  that  the  commencement  of  certain  projects  or  parts  of  a  project  is,  in
some  cases,  being  delayed  due  to  global  supply  chain  constraints  adversely  impacting  the  timely  availability  of  necessary
equipment  and  supplies.    We  currently  believe  that  these  temporary  circumstances  will  gradually  diminish  over  the  short  to
medium term.

Offshore  drilling  activity  is  increasing  in  every  ultra-deepwater  geographic  sector.    South  America,  the  U.S.
Gulf of Mexico and, increasingly, West Africa remain key ultra-deepwater market sectors.  We have seen significant increases
in dayrates for projects in the U.S. Gulf of Mexico and, particularly, in Brazil, trends that we expect will continue.  In Norway,
the  largest  market  for  harsh  environment  rigs,  we  do  not  expect  many  new  projects  to  commence  before  late  2023,  but  we
expect demand for rigs in this market will accelerate thereafter through 2026 due to previously enacted Norwegian tax incentive
programs.  Given the highly regulated nature of the Norwegian market and the limited number of rigs qualified to operate in it,
we  anticipate  an  increase  in  dayrates  commensurate  with  the  increased  demand.    We  are  also  encouraged  by  projects  being
announced  in  the  United  Kingdom,  Namibia,  South  Africa  and  Australia  that  require  high-specification,  harsh  environment
semisubmersibles.  As expected, these opportunities are attracting rigs currently working in Norway, thereby further reducing
rig supply and potentially accelerating dayrate increases for the remaining assets in the region.

We  expect  global  energy  demand  to  continue  to  increase  in  both  member  and  non-member  countries  of  the
Organization for Economic Co-operation and Development.  Forecasts indicate that non-member countries will experience the
largest population growth and require the most significant improvement in living standards, compounding the effect on energy
demand for the foreseeable future.  We believe that this increase in global energy demand will result in meaningful incremental
demand for oil and gas.  In the context of the pronounced decline in investment in exploration and production activities over the
last  decade,  we  anticipate  that  a  prolonged  period  of  elevated  hydrocarbon  prices  and  investment  in  drilling  activity  will  be
necessary to meet this demand.

Table of Contents

With deepwater and harsh environment fields generating robust economic returns versus other hydrocarbon sources,
combined with their comparably low carbon intensity of production, we expect a significant portion of the required spending in
fossil  fuel  development  will  be  allocated  to  deepwater  and  harsh  environment  projects.    As  there  are  now  fewer  high-
specification offshore drilling rigs capable of operating in these markets, we believe that this increase in demand will support
further improvement of dayrates.

As of February 9, 2023, our contract backlog was $8.54 billion compared to $7.27 billion as of October 13, 2022.  The
risks of drilling project delays, contract renegotiations and contract terminations and cancellations have diminished as oil prices
have improved and stabilized.

Fleet status—We refer to the availability of our rigs in terms of the uncommitted fleet rate.  The uncommitted fleet
rate is defined as the number of uncommitted days divided by the total number of rig calendar days in the measurement period,
expressed  as  a  percentage.   An  uncommitted  day  is  defined  as  a  calendar  day  during  which  a  rig  is  idle  or  stacked,  is  not
contracted to a customer and is not committed to a shipyard.  The uncommitted fleet rates exclude the effect of priced options.
 As of February 9, 2023, our uncommitted fleet rates for each of the five years in the period ending December 31, 2027 were as
follows:

Uncommitted fleet rate
Ultra-deepwater floaters
Harsh environment floaters

PERFORMANCE AND OTHER KEY INDICATORS

Contract backlog—We believe our industry leading contract backlog sets us apart from the competition and provides
indicators  of  our  future  revenue-earning  opportunities.    Contract  backlog  is  defined  as  the  maximum  contractual  operating
dayrate  multiplied  by  the  number  of  days  remaining  in  the  firm  contract  period,  excluding  revenues  for  mobilization,
demobilization,  contract  preparation,  other  incentive  provisions  or  reimbursement  revenues,  which  are  not  expected  to  be
significant to our contract drilling revenues.  The contract backlog represents the maximum contract drilling revenues that can
be earned considering the contractual operating dayrate in effect during the firm contract period.  The contract backlog for our
fleet was as follows:

Our  contract  backlog  includes  only  firm  commitments,  including  amounts  associated  with  our  contracted  newbuild
units under construction, which are represented by signed drilling contracts or, in some cases, by other definitive agreements
awaiting contract execution.  It does not include conditional agreements and options to extend firm commitments.

The  average  contractual  dayrate  relative  to  our  contract  backlog  is  defined  as  the  average  maximum  contractual
operating dayrate to be earned per operating day in the measurement period.  An operating day is defined as a day for which a
rig is contracted to earn a dayrate during the firm contract period after operations commence.  At February 9, 2023, the contract
backlog and average contractual dayrates for our fleet were as follows:

The actual amount of revenues earned and the actual periods in which revenues are earned will differ from the amounts
and periods shown in the tables above due to various factors, including shipyard and maintenance projects, unplanned downtime
and  other  factors  that  result  in  lower  applicable  dayrates  than  the  full  contractual  operating  dayrate.   Additional  factors  that
could  affect  the  amount  and  timing  of  actual  revenues  to  be  recognized  include  customer  liquidity  issues  and  contract
terminations that may be available to our customers under certain circumstances.

The contractual operating dayrate may be higher than the actual dayrate we ultimately receive because an alternative
contractual dayrate, such as a waiting-on-weather rate, repair rate, standby rate or force majeure rate, may apply under certain
circumstances.  The

contractual operating dayrate may also be higher than the actual dayrate we ultimately receive because of a number of factors,
including  rig  downtime  or  suspension  of  operations.    In  certain  contracts,  the  actual  dayrate  may  be  reduced  to  zero  if,  for
example, repairs extend beyond a stated period of time.  See “Part I. Item 1A. Risk Factors—Risks related to our business—Our
current backlog of contract drilling revenues may not be fully realized.”

Average daily revenue—We believe average daily revenue provides a comparative measurement unit for our revenue-
earning  performance.   Average  daily  revenue  is  defined  as  operating  revenues,  excluding  revenues  for  contract  terminations,
reimbursements and contract intangible amortization, earned per operating day.  The average daily revenue for our fleet was as
follows:

Our  average  daily  revenue  fluctuates  relative  to  market  conditions  and  our  revenue  efficiency.    The  average  daily
revenue may be affected by incentive performance bonuses or penalties or demobilization fee revenues.  Our total fleet average
daily revenue is affected by the mix of rig classes being operated.  Midwater floaters, for example, which we no longer operate,
are typically contracted at lower dayrates compared to ultra-deepwater floaters and harsh environment floaters.  Revenues for a
contracted newbuild unit are included in the calculation when the rig commences operations upon acceptance by the customer.
  We  remove  rigs  from  the  calculation  upon  disposal  or  classification  as  held  for  sale,  unless  we  continue  to  operate  rigs
subsequent to sale, in which case we remove the rigs at the time of completion or novation of the contract.

Revenue efficiency—We believe revenue efficiency measures our ability to ultimately convert our contract backlog
into  revenues.    Revenue  efficiency  is  defined  as  actual  operating  revenues,  excluding  revenues  for  contract  terminations  and
reimbursements,  for  the  measurement  period  divided  by  the  maximum  revenue  calculated  for  the  measurement  period,
expressed as a percentage.  Maximum revenue is defined as the greatest amount of contract drilling revenues the drilling unit
could earn for the measurement period, excluding revenues for incentive provisions, reimbursements and contract terminations.
 The revenue efficiency rates for our fleet were as follows:

Our revenue efficiency rate varies due to revenues earned under alternative contractual dayrates, such as a waiting-on-
weather rate, repair rate, standby rate, force majeure rate or zero rate, that may apply under certain circumstances.  Our revenue
efficiency rate is also affected by incentive performance bonuses or penalties.  We include newbuilds in the calculation when the
rigs  commence  operations  upon  acceptance  by  the  customer.   We  exclude  rigs  that  are  not  operating  under  contract,  such  as
those that are stacked.

Rig  utilization—We  present  our  rig  utilization  as  an  indicator  of  our  ability  to  secure  work  for  our  fleet.    Rig
utilization is defined as the total number of operating days divided by the total number of rig calendar days in the measurement
period, expressed as a percentage.  The rig utilization rates for our fleet were as follows:

Our rig utilization rate declines as a result of idle and stacked rigs and during shipyard and mobilization periods to the
extent these rigs are not earning revenues.  We include newbuilds in the calculation when the rigs commence operations upon
acceptance by the customer.  We remove rigs from the calculation upon disposal or classification as held for sale.  Accordingly,
our rig utilization can increase when we remove idle or stacked units from our fleet.

Contract drilling revenues—Contract drilling revenues increased for the year ended December 31, 2022, compared to
the  year  ended  December  31,  2021,  primarily  due  to  the  following:  (a)  approximately  $25  million  resulting  from
Deepwater Atlas, which was placed into service in October 2022, (b) approximately $20 million resulting from increased rig
utilization, (c) approximately $10 million resulting from higher early termination revenues and (d) approximately $10 million
resulting from higher reimbursable revenues.  These increases were partially offset by (a) approximately $40 million resulting
from lower dayrates and (b) approximately $5 million resulting from lower fleet revenue efficiency.

Costs  and  expenses—Operating  and  maintenance  costs  and  expenses  decreased  for  the  year  ended  December  31,
2022, compared to the year ended December 31, 2021, primarily due to the following: (a) approximately $35 million resulting
from the effect of favorable exchange rates, (b) approximately $28 million resulting from the allowance for excess materials and
supplies  due  to  the  identification,  in  the  year  ended  December  31,  2021,  of  parts  that  were  in  excess  of  our  expected  future
usage,  (c)  approximately  $15  million  resulting  from  reduced  rig  out-of-service  maintenance  costs  and  (d)  approximately
$5 million incurred on rigs sold in the year ended December 31, 2021.  These decreases were partially offset by the following
increases:  (a)  approximately  $25  million  resulting  from  personnel  compensation  increases,  (b)  approximately  $20  million
resulting  from  increased  rig  operating  activities,  (c)  approximately  $15  million  resulting  from  Deepwater  Atlas  and
(d) approximately $10 million resulting from higher customer reimbursable costs.

Depreciation and amortization expense decreased for the year ended December 31, 2022, compared to the year ended
December  31,  2021,  primarily  due  to  (a)  approximately  $17  million  resulting  from  assets  that  had  reached  the  end  of  their
useful lives or had been retired, partially offset by (b) approximately $10 million of increased depreciation associated with our
newbuild ultra-deepwater drillship and other property and equipment placed into service in the year ended December 31, 2022.

General  and  administrative  expense  increased  for  the  year  ended  December  31,  2022,  compared  to  the  year  ended
December 31, 2021, primarily due to the following: (a) approximately $8 million of increased costs for information systems and
technology and (b) approximately $3 million of increased costs for strategy and innovation.

Disposal  of  assets—In  the  year  ended  December  31,  2021,  we  recognized  an  aggregate  net  loss  of  $57  million,
primarily associated with the sale of a harsh environment floater and related assets.  In the years ended December 31, 2022 and
2021, we recognized an aggregate net loss of $10 million and $5 million, respectively, associated with the disposal of assets
unrelated to rig sales.

Other income and expense—Interest expense, net of amounts capitalized, increased in the year ended December 31,
2022, compared to the year ended December 31, 2021, primarily due to the following: (a) an increase of $157 million resulting
from  the  fair  value  adjustment  of  the  bifurcated  compound  exchange  feature  embedded  in  the  4.625%  Senior  Guaranteed
Exchangeable Bonds and (b) an increase of $15 million resulting from borrowings under the Shipyard Loans, partially offset by
(c) a decrease of $41 million resulting from

- 30 -

    
 
    
    
    
 
 
Table of Contents

debt repaid as scheduled or early retired and (d) a decrease of $23 million resulting from increased interest capitalized for our
newbuild construction projects.

In  the  year  ended  December  31,  2022,  we  recognized  an  aggregate  net  gain  on  the  retirement  of  debt,  primarily
associated with the retirement of $116 million aggregate principal amount of debt as a result of the 2022 Private Exchange.  In
the year ended December 31, 2021, we recognized an aggregate net gain on the retirement of debt, primarily associated with the
retirement of $323 million aggregate principal amount of debt as a result of the private exchanges completed in February 2021
(the “2021 Private Exchange”).

Other expense, net, increased in the year ended December 31, 2022, compared to the year ended December 31, 2021,
primarily due to the following: (a) income of $32 million resulting from settlement of litigation recognized in the year ended
December  31,  2021,  (b)  increased  loss  of  $11  million  related  to  our  investment  in  Nauticus  Robotics,  Inc.  (“Nauticus”),
(c)  reduced  income  of  $7  million  related  to  our  dual-activity  patent,  (d)  increased  losses  of  $7  million  resulting  from  net
changes to currency exchange rates, and (e) reduced income of $5 million related to the non-service components of net periodic
benefit  income,  partially  offset  by  (f)  reduced  losses  of  $33  million  related  to  our  investment  in  Orion  Holdings  (Cayman)
Limited (“Orion”).

Income tax expense—In the years ended December 31, 2022 and 2021, our effective tax rate was (10.4) percent and
(25.7) percent, respectively, based on loss before income tax expense.  In the years ended December 31, 2022 and 2021, the
aggregate  effect  of  discrete  period  tax  items  was  a  net  tax  benefit  of  $19  million  and  net  tax  expense  of  $47  million,
respectively.  In the year ended December 31, 2022, such discrete items included settlement and expiration of various uncertain
tax positions, changes to valuation allowances, operational restructuring and gains due to exchange rate changes.  In the year
ended  December  31,  2021,  such  discrete  items  included  the  effect  of  tax  law  changes  in  Switzerland  and  jurisdictional
ownership  changes  of  certain  assets,  loss  on  disposal  of  assets,  expiration  and  settlements  of  various  uncertain  tax  positions,
gain on retirement of debt, changes to our allowance for excess materials and loss on impairment of an equity investment.  In
the  years  ended  December  31,  2022  and  2021,  our  effective  tax  rate,  excluding  discrete  items,  was  (13.6)  percent  and
(18.5) percent, respectively, based on loss before income tax expense.  In the year ended December 31, 2022 compared to the
year ended December 31, 2021, our effective tax rate increased primarily due to changes in the relative blend of income from
operations in certain jurisdictions.

Due  to  our  operating  activities  and  organizational  structure,  our  income  tax  expense  does  not  change  proportionally
with our income before income taxes.  Significant decreases in our income before income taxes typically lead to higher effective
tax rates, while significant increases in income before income taxes can lead to lower effective tax rates, subject to the other
factors  impacting  income  tax  expense  noted  above.    With  respect  to  the  effective  tax  rate  calculation  for  the  year  ended
December  31,  2022,  a  significant  portion  of  our  income  tax  expense  was  generated  in  countries  in  which  income  taxes  are
imposed  or  treated  to  be  imposed  on  gross  revenues,  with  the  most  significant  of  these  countries  being  Angola  and  India.
 Conversely, during this period, the most significant countries in which we incurred income taxes that were based on income
before  income  tax  included  the  U.S.,  Hungary  and  Switzerland.    Our  rig  operating  structures  further  complicate  our  tax
calculations, especially in instances where we have more than one operating structure for the taxing jurisdiction and, thus, more
than one method of calculating taxes depending on the operating structure utilized by the rig under the contract.

LIQUIDITY AND CAPITAL RESOURCES

Sources and uses of cash

At December 31, 2022, we had $683 million in unrestricted cash and cash equivalents and $308 million in restricted
cash and cash equivalents.  In the year ended December 31, 2022, our primary sources of cash were net cash provided by our
operating  activities,  net  cash  proceeds  from  the  issuance  of  shares  under  the  ATM  Program  and  net  cash  proceeds  from  the
issuance of debt.  Our primary uses of cash were debt repayments and capital expenditures.

Net  cash  used  in  financing  activities  decreased  primarily  due  to  (a)  net  cash  proceeds  from  the  issuance  of  the
4.625% Senior Guaranteed Exchangeable Bonds in the year ended December 31, 2022, (b) increased net cash proceeds from the

Sources and uses of liquidity

Overview—We expect to use existing unrestricted cash balances, internally generated cash flows, borrowings under
our Secured Credit Facility or proceeds from the disposal of assets or the issuance of debt or shares to fulfill anticipated near-
term obligations, which may include capital expenditures, working capital and other operational requirements, scheduled debt
maturities  or  other  payments.    We  may  consider  establishing  additional  financing  arrangements  with  banks  or  other  capital
providers,  and  subject  to  market  conditions  and  other  factors,  we  may  be  required  to  provide  collateral  for  any  such  future
financing arrangements.

We  have  generated  positive  cash  flows  from  operating  activities  over  recent  years  and,  although  we  cannot  provide
assurances, we currently expect that such cash flows will continue to be positive over the next year.  Among other factors, if
general economic, financial, industry or business conditions deteriorate, if we experience poor operating results, or if we incur
costs to, for example, reactivate, stack or otherwise assure the marketability of our fleet, our cash flows from operations may be
reduced or negative.

We continue to evaluate additional potential liability management transactions in connection with our ongoing efforts
to prudently manage our capital structure and improve our liquidity.  In each case subject to then-existing market conditions and
our  expected  liquidity  needs,  among  other  factors,  we  may  continue  to  use  existing  unrestricted  cash  balances,  internally
generated  cash  flows  and  proceeds  from  asset  sales  to  pursue  liability  management  transactions,  including  among  others,
purchasing  or  exchanging  one  or  more  existing  series  of  our  debt  securities  in  the  open  market,  in  privately  negotiated
transactions, through tender offers or through exchange offers.  Any future purchases, exchanges or other transactions may be
on the same terms or on terms that are more or less favorable to holders than the terms of any prior transaction, including our
previous exchange transactions.  We can provide no assurance as to which, if any, of these alternatives, or combinations thereof,
we may choose to pursue in the future, if at all, or as to the timing with respect to any future transactions.

Our ability and willingness to access the debt and equity markets is a function of a variety of factors, including, among
others, general economic, industry or market conditions, market perceptions of us and our industry and credit rating agencies’
views of our debt.  General economic or market conditions could have an adverse effect on our business and financial position
and  on  the  business  and  financial  position  of  our  customers  suppliers  and  lenders  and  could  affect  our  ability  to  access  the
capital  markets  on  acceptable  terms  or  at  all  and  our  future  need  or  ability  to  borrow  under  our  Secured  Credit  Facility.    In
addition  to  our  potential  sources  of  funding,  the  effects  of  such  global  events  could  impact  our  liquidity  or  need  to  alter  our
allocation or sources of capital, implement further cost reduction measures and change our financial strategy.  Additionally, the
rating of the majority of our long-term debt, which is below investment grade, is causing us to experience increased fees and
interest rates under our Secured Credit Facility and agreements governing certain of our senior notes.  Future downgrades may
further restrict our ability to access the debt market for sources of capital and may negatively impact the cost of such capital at a
time when we would like, or need, to access such markets, which could have an impact on our flexibility to react to changing
economic and business conditions.

Debt  issuances—In  January  2023,  we  issued  $525  million  aggregate  principal  amount  of  8.375%  Senior  Secured
Notes, and we received $515 million aggregate cash proceeds, net of issue costs.  The 8.375% Senior Secured Notes are secured
by  the  assets  and  earnings  associated  with  the  ultra-deepwater  floater  Deepwater Titan  and  the  equity  of  the  wholly  owned
subsidiary that owns or operates

- 32 -

 
   
 
 
 
    
 
 
Table of Contents

the collateral rig.  Additionally, we are required to maintain certain balances in a restricted cash account to satisfy debt service
requirements.  We may redeem all or a portion of the 8.375% Senior Secured Notes on or prior to February 1, 2025 at a price
equal to 100 percent of the aggregate principal amount plus a make-whole premium, and subsequently, at specified redemption
prices.

In January 2023, we issued $1.175 billion aggregate principal amount of 8.75% Senior Secured Notes, and we received
$1.157  billion  aggregate  cash  proceeds,  net  of  issue  costs.    The  8.75%  Senior  Secured  Notes  are  fully  and  unconditionally
guaranteed  on  an  unsecured  basis  by  Transocean  Ltd.  and  on  a  limited  senior  secured  basis  by  certain  of  our  wholly  owned
subsidiaries.    The  8.75%  Senior  Secured  Notes  are  secured  by  a  lien  on  the  ultra-deepwater  floaters  Deepwater  Pontus,
Deepwater  Proteus  and  Deepwater  Thalassa  and 
floaters  Transocean  Enabler  and
Transocean Encourage,  together  with  certain  related  assets.   Additionally,  we  are  required  to  maintain  certain  balances  in  a
restricted cash account to satisfy debt service requirements.

the  harsh  environment 

Early  debt  retirement—In  January  2023,  in  connection  with  the  issuance  of  the  8.75%  Senior  Secured  Notes,  we
made  an  aggregate  payment  of  $1.156  billion,  including  a  make-whole  premium,  to  redeem  the  remaining  outstanding
$311 million, $240 million, $250 million, and $336 million aggregate principal amount of the 5.875% Senior Secured Notes,
the 7.75% Senior Secured Notes, the 6.25% Senior Secured Notes and the 6.125% Senior Secured Notes, respectively.

In  January  2022,  we  made  an  aggregate  cash  payment  of  $18  million  to  repay  the  then  outstanding  equivalent
aggregate principal amount of the 5.52% Senior Secured Notes, and as a result, the noteholders subsequently released all liens,
the  mortgage  on  the  secured  rig  and  $106  million  from  restricted  cash  accounts.    In  July  2022,  we  made  an  aggregate  cash
payment of $27 million to redeem the then outstanding equivalent aggregate principal amount of the 3.80% Senior Notes.

In October 2022, the harsh environment floater Transocean Equinox, which is held as collateral for the 5.375% Senior
Secured Notes, concluded its drilling contract following a notice received from the customer in September 2022.  As required
under the indenture governing such notes, in January 2023, we made a cash payment of $121 million to redeem an equivalent
aggregate principal amount of the outstanding securities.  Additionally, in January 2023, the trustee notified holders of our intent
to  redeem  the  remaining  outstanding  $122  million  aggregate  principal  amount  of  notes  for  an  equivalent  aggregate  cash
payment, expected to be made on February 24, 2023.

In the year ended December 31, 2021, we made an aggregate cash payment of $79 million to repurchase in the open

market an equivalent aggregate principal amount of our debt securities.

Shipyard  financing  arrangement—We  established  the  Shipyard  Loans  to  finance  all  or  a  portion  of  the  final
payments  expected  to  be  owed  to  the  shipyard  upon  delivery  of  the  ultra-deepwater  floaters  Deepwater  Atlas  and
Deepwater Titan.    In  June  2022,  we  borrowed  $349  million  under  one  of  the  Shipyard  Loans  and  made  a  cash  payment  of
$46  million  to  satisfy  the  final  milestone  payment  due  upon  delivery  of  Deepwater Atlas.    In  December  2022,  we  borrowed
$90 million under the other Shipyard Loan and made a cash payment of $325 million to satisfy the final milestone payment due
upon delivery of Deepwater Titan.   The  Shipyard  Loans  are  guaranteed  by  Transocean  Inc.    Borrowings  under  the  Shipyard
Loan for Deepwater Atlas  are  secured  by,  among  other  security,  a  lien  on  the  rig.    Borrowings  under  the  Shipyard  Loan  for
Deepwater Titan are unsecured.  We have the right to prepay the outstanding borrowings, in full or in part, without penalty.  The
Shipyard  Loans  contain  covenants  that,  among  other  things,  limits  the  ability  of  the  subsidiary  owners  of  the  drilling  rigs  to
incur certain types of additional indebtedness or make certain additional commitments or investments.

Debt  exchanges—In  September  2022,  we  issued  $300  million  aggregate  principal  amount  of  4.625%  Senior
Guaranteed  Exchangeable  Bonds  in  connection  with  exchange  and  purchase  agreements.    Pursuant  to  the  exchange  and
purchase agreements, we exchanged (a) $73 million aggregate principal amount of the 0.50% Exchangeable Senior Bonds for
(i) $73 million aggregate principal amount of the 4.625% Senior Guaranteed Exchangeable Bonds and (ii) 6.7 million warrants
to purchase Transocean Ltd. shares, and (b) $43 million aggregate principal amount of the 7.25% Senior Notes for $39 million
aggregate  principal  amount  of  the  4.625%  Senior  Guaranteed  Exchangeable  Bonds.    Additionally,  we  sold  $188  million
aggregate principal amount of the 4.625% Senior Guaranteed Exchangeable Bonds and issued 15.5 million warrants to purchase
Transocean Ltd. shares for aggregate net cash proceeds of $188 million.  On or after March 30, 2026, we may redeem for cash
all or a portion of the 4.625% Senior Guaranteed Exchangeable Bonds at a price equivalent to the aggregate principal amount to
be redeemed if the closing price of our shares has been greater than 115 percent of the exchange price for a period of at least
20 trading days.

In February 2021, we issued $294 million aggregate principal amount of the 4.00% senior guaranteed exchangeable
bonds  due  December  2025  (the  “4.00%  Senior  Guaranteed  Exchangeable  Bonds”)  and  made  an  aggregate  cash  payment  of
$11  million  in  the  2021  Private  Exchange  for  $323  million  aggregate  principal  amount  of  the  0.50%  Exchangeable  Senior
Bonds.   The  4.00%  Senior  Guaranteed  Exchangeable  Bonds  are  guaranteed  by  Transocean  Ltd.  and  the  same  subsidiaries  of
Transocean  Inc.  that  guarantee  the  2.50%  senior  guaranteed  exchangeable  bonds  due  January  2027  (the  “2.50%  Senior
Guaranteed Exchangeable Bonds”) and the 11.50% senior guaranteed notes due January 2027.  The indenture that governs the
4.00%  Senior  Guaranteed  Exchangeable  Bonds  also  requires  such  bonds  to  be  repurchased  upon  the  occurrence  of  certain
fundamental changes and events, at specified prices depending on the particular fundamental change or event, which include
changes  and  events  related  to  certain  (i)  change  of  control  events  applicable  to  Transocean  Ltd.  or  Transocean  Inc.,  (ii)  the
failure of our shares to be listed or quoted on a national securities exchange and (iii) specified tax matters.  The 4.00% Senior
Guaranteed  Exchangeable  Bonds  may  be  exchanged  at  any  time  prior  to  the  close  of  business  on  the  second  business  day
immediately preceding the maturity date at a current exchange rate of 190.4762 Transocean Ltd. shares per $1,000 note, which
implies  an  exchange  price  of  $5.25  per  share,  subject  to  adjustment  upon  the  occurrence  of  certain  events,  and  any  such
exchange may be settled in cash, Transocean Ltd. shares or a combination of cash and Transocean Ltd. shares, at our election.

Share issuance—We intend to use the net proceeds from the sale of our shares under the ATM Program for general
corporate purposes, which may include, among other things the repayment or refinancing of indebtedness and the funding of
working capital, capital expenditures, investments and additional balance sheet liquidity.  In the years ended December 31, 2022
and  2021,  we  received  aggregate  cash  proceeds  of  $263  million  and  $158  million,  respectively,  net  of  issue  costs,  for  the
aggregate sale of 61.0 million shares and 36.1 million shares, respectively, under the ATM Program.

Secured  Credit  Facility—In  July  2022,  we  amended  the  bank  credit  agreement  for  our  Secured  Credit  Facility  to,
among other things, (i) extend the maturity date from June 22, 2023 to June 22, 2025, (ii) reduce the borrowing capacity from
$1.33  billion  to  $774  million  through  June  22,  2023,  and  thereafter  reduce  the  borrowing  capacity  to  $600  million  through
June 22, 2025 and (iii) replace our ability to borrow under the Secured Credit Facility at the reserve adjusted London Interbank
Offered Rate plus a margin (the “Secured Credit Facility Margin”) with the ability to borrow under the Secured Credit Facility
at a forward looking term rate based on the secured overnight financing rate (“Term SOFR”) plus the Secured Credit Facility
Margin and a Term SOFR spread adjustment of 0.10 percent.  The Secured Credit Facility is subject to permitted extensions and
certain  early  maturity  triggers,  including  if  on  any  date  the  aggregate  amount  of  scheduled  principal  repayments  of
indebtedness, with certain exceptions, due within 91 days thereof is equal to or in excess of $200 million and available cash is
less than $250 million.  The amended secured credit facility also permits us to increase the aggregate amount of commitments
by up to $250 million.  The Secured Credit Facility is guaranteed by Transocean Ltd. and certain wholly owned subsidiaries.
 The Secured Credit Facility is secured by, among other things, a lien on nine of our ultra-deepwater floaters and two of our
harsh environment floaters.

The Secured Credit Facility contains covenants that, among other things, include maintenance of a minimum guarantee
coverage  ratio  of  3.0  to  1.0,  a  minimum  collateral  coverage  ratio  of  2.1  to  1.0,  a  maximum  debt  to  capitalization  ratio  of
0.60 to 1.00 and minimum liquidity of $500 million.  The Secured Credit Facility also restricts the ability of Transocean Ltd.
and certain of our subsidiaries to, among other things, merge, consolidate or otherwise make changes to the corporate structure,
incur liens, incur additional indebtedness, enter into transactions with affiliates and pay dividends and other distributions.  In
order to utilize the Secured Credit Facility, we must, at the time of the borrowing request, be in full compliance with the terms
and  conditions  of  the  Secured  Credit  Facility  and  make  certain  representations  and  warranties,  including  with  respect  to
compliance with laws and solvency, to the lenders.  Repayment of borrowings under the Secured Credit Facility are subject to
acceleration upon the occurrence of an event of default.  Under the agreements governing certain of our debt and finance lease,
we  are  also  subject  to  various  covenants,  including  restrictions  on  creating  liens,  engaging  in  sale/leaseback  transactions  and
engaging  in  certain  merger,  consolidation  or  reorganization  transactions.    A  default  under  our  public  debt  indentures,  the
agreements governing our senior secured notes, our finance lease contract or any other debt owed to unaffiliated entities that
exceeds $125 million could trigger a default under the Secured Credit Facility and, if not waived by the lenders, could cause us
to lose access to the Secured Credit Facility.  At February 14, 2023, we had no borrowings outstanding, $6 million of letters of
credit issued, and we had $767 million of available borrowing capacity under the Secured Credit Facility.

Equity  and  debt  investments—In  the  years  ended  December  31,  2022  and  2021,  we  made  cash  investments  of
$25 million and $34 million, respectively, in the equity and debt of certain unconsolidated affiliates, such as Orion and Liquila,
that own drilling units.  In the year ended December 31, 2022, we made a cash contribution of $15 million to Liquila, which
was  used  by  Liquila  to  make  the  initial  payment  to  the  shipyard  to  acquire  the  ultra-deepwater  drillship  Deepwater  Aquila.
 Additionally,  in  the  year  ended  December  31,  2022,  we  made  an  aggregate  cash  contribution  of  $10  million  to  our  equity
investment  in  Orion,  the  company  that,  through  its  wholly  owned  subsidiary,  owns  the  harsh  environment  floater
Transocean  Norge.    In  June  2021,  we  agreed  to  participate  in  a  financing  arrangement  for  Orion,  at  a  rate  of  33  percent,
equivalent to our ownership interest in Orion, and made a cash investment of $33 million in the loan facility.

In  February  2023,  we  agreed  to  make  an  investment  for  a  noncontrolling  ownership  interest  in  Global  Sea  Mineral
Resources, a Belgian company and leading developer of nodule collection technology, which is engaged in the development and
exploration of deep-sea polymetallic nodules that contain metals critical to the growing renewable energy market.  In addition to
a cash investment of $10 million, we agreed to contribute the ultra-deepwater drillship Ocean Rig Olympia, and we expect to
contribute engineering services in the future.

In the year ended December 31, 2022, we made an aggregate cash investment of $22 million in the equity and debt of
certain  other  unconsolidated  affiliates  that  are  involved  in  researching  and  developing  technology  to  improve  efficiency,
reliability, sustainability and safety in drilling and other activities.  We hold an equity investment in Nauticus, a company that
develops  highly  sophisticated,  ultra-sustainable  marine  robots  and  intelligent  software  to  power  them,  which,  following  the
completion of a business combination with a publicly traded special purpose acquisition company in September 2022, became a
publicly  listed  company,  the  common  shares  of  which  trade  on  the  NASDAQ  exchange  under  the  ticker  symbol  “KITT.”
  Additionally,  we  hold  equity  and  debt  investments  in  Ocean  Minerals  LLC,  the  parent  company  of  Moana  Minerals  Ltd.
(“Moana”),  a  Cook  Islands  subsea  resource  development  company  that  intends  to  extract  polymetallic  nodules.   We  retain  a
priority  right  to  provide  deepwater  nodule  extraction  services  to  Moana,  and  together  with  Moana  and  others,  we  intend  to
extract the nodules in an environmentally responsible way by employing existing and developing new technologies.

Exchangeable bonds—The indentures that govern the 4.00% Senior Guaranteed Exchangeable Bonds, 2.50% senior
guaranteed exchangeable bonds due January 2027 and the 4.625% Senior Guaranteed Exchangeable Bonds each requires such
bonds to be repurchased upon the occurrence of certain fundamental changes and events, at specified prices depending on the
particular  fundamental  change  or  event,  which  include  changes  and  events  related  to  certain  (i)  change  of  control  events
applicable  to  Transocean  Ltd.  or  Transocean  Inc.,  (ii)  the  failure  of  our  shares  to  be  listed  or  quoted  on  a  national  securities
exchange  and  (iii)  specified  tax  matters.    Additionally,  the  4.00%  Senior  Guaranteed  Exchangeable  Bonds  and  the
4.625%  Senior  Guaranteed  Exchangeable  Bonds  may  be  exchanged  at  any  time  prior  to  the  close  of  business  on  the  second
business day immediately preceding the maturity date at the effective

exchange  rate,  and  any  such  exchange  may  be  settled  in  cash,  Transocean  Ltd.  shares  or  a  combination  of  cash  and
Transocean Ltd. shares, at our election.

Share repurchase program—In May 2009, at our annual general meeting, our shareholders approved and authorized
our board of directors, at its discretion, to repurchase for cancellation any amount of our shares for an aggregate purchase price
of up to CHF 3.50 billion.  On February 12, 2010, our board of directors authorized our management to implement the share
repurchase  program.    At  December  31,  2022,  the  authorization  remaining  under  the  share  repurchase  program  was  for  the
repurchase of our outstanding shares for an aggregate purchase price of up to CHF 3.24 billion, equivalent to $3.51 billion.  We
intend to fund any repurchases using available cash balances and cash from operating activities.  The share repurchase program
could be suspended or discontinued by our board of directors or company management, as applicable, at any time.  We may
decide,  based  on  our  ongoing  capital  requirements,  the  price  of  our  shares,  regulatory  and  tax  considerations,  cash  flow
generation,  the  amount  and  duration  of  our  contract  backlog,  general  market  conditions,  debt  rating  considerations  and  other
factors,  that  we  should  retain  cash,  reduce  debt,  make  capital  investments  or  acquisitions  or  otherwise  use  cash  for  general
corporate purposes.  Decisions regarding the amount, if any, and timing of any share repurchases will be made from time to
time based on these factors.  Any repurchased shares under the share repurchase program would be held by us for cancellation
by the shareholders at a future general meeting of shareholders.  See “Item 5. Market for Registrant’s Common Equity, Related
Shareholder Matters and Issuer Purchases of Equity Securities—Shareholder Matters.”

Contractual obligations—At December 31, 2022, our contractual obligations stated at face value, were as follows:

As  of  December  31,  2022,  our  defined  benefit  pension  and  other  postemployment  plans  represented  an  aggregate
liability of $174 million, representing the aggregate projected benefit obligation, net of the aggregate fair value of plan assets.
  The  carrying  amount  of  this  liability  is  influenced  by,  among  others,  significant  current  and  future  assumptions,  funding
contributions,  returns  on  plan  assets,  participant  demographics,  and  plan  amendments.    We  excluded  this  amount  from  our
contractual  obligations  presented  above  due  to  the  uncertainties  resulting  from  these  factors  and  because  the  amount  is  not
representative  of  future  liquidity  requirements.    See  Notes  to  Consolidated  Financial  Statements—Note  9—Postemployment
Benefit Plans.

As of December 31, 2022, we had unrecognized tax benefits of $471 million, including interest and penalties, against
which  we  recorded  net  operating  loss  deferred  tax  assets  of  $383  million,  resulting  in  net  unrecognized  tax  benefits  of
$88  million,  including  interest  and  penalties,  that  upon  reversal  would  favorably  impact  our  effective  tax  rate.   Although  a
portion  of  these  could  settle  or  reverse  in  the  coming  year,  we  have  excluded  this  amount  from  our  contractual  obligations
presented  above  due  to  the  high  degree  of  uncertainty  regarding  the  timing  of  future  cash  outflows  associated  with  these
liabilities  and  the  period  in  which  any  cash  settlement  may  be  made  with  the  respective  taxing  authorities.    See  Notes  to
Consolidated Financial Statements—Note 10—Income Taxes.

Other  commercial  commitments—We  have  other  commercial  commitments,  such  as  standby  letters  of  credit  and
surety bonds that guarantee our performance as it relates to our drilling contracts, insurance, customs, tax and other obligations
in various jurisdictions.  The cash obligations of these commitments, which are primarily geographically concentrated in Brazil,
are not normally called because we typically comply with the underlying performance requirements.  Standby letters of credit
are  issued  under  various  committed  and  uncommitted  credit  lines,  some  of  which  require  cash  collateral.   At  December  31,
2022, the aggregate cash collateral held by banks for letters of credit and surety bonds was $7 million.

At December 31, 2022, these obligations stated in U.S. dollar equivalents and their time to expiration were as follows:

We have established a wholly owned captive insurance company to insure various risks of our operating subsidiaries.
 Access to the cash and cash equivalents of the captive insurance company may be limited due to local regulatory restrictions.
 At  December  31,  2022,  the  captive  insurance  company  held  cash  and  cash  equivalents  of  $44  million,  and  such  balance  is
expected to range from $25 million to $75 million through December 31, 2023.  The balance of the cash and cash equivalents
held by the captive insurance company varies, depending on (i) premiums received and (ii) the timing and magnitude of claims
and dividends paid by the captive insurance company.

Drilling fleet

Expansion—From  time  to  time,  we  review  possible  acquisitions  of  businesses  and  drilling  rigs,  as  well  as
noncontrolling interests in other companies, and we may make significant future capital commitments for such purposes.  We
may also consider investments related to major rig upgrades, new rig construction, or the acquisition of a rig under construction.
 Any  such  acquisition  or  investment  could  involve  the  payment  by  us  of  a  substantial  amount  of  cash  or  the  issuance  of  a
substantial  number  of  additional  shares  or  other  securities.    Our  failure  to  subsequently  secure  drilling  contracts  in  these
instances, if not already secured, could have an adverse effect on our results of operations or cash flows.

In the year ended December 31, 2022, we made a cash contribution of $15 million to Liquila, which represented our
proportionate contribution that was used to make the initial payment to the shipyard to acquire the newbuild ultra-deepwater
drillship Deepwater Aquila  for  a  purchase  price  of  approximately  $200  million.    The  seventh  generation,  high-specification
drillship  is  designed  to  be  equipped  with  our  patented  dual  activity,  a  1,400  short-ton  hookload,  large  deck  space,  high  load
capacities, large deck space and will be dual-stack ready.  We maintain the exclusive right to market and manage the operations
of the rig, which is expected to be delivered from the shipyard in the third quarter of 2023.

In  the  years  ended  December  31,  2022  and  2021,  we  made  capital  expenditures  of  $717  million  and  $208  million,
respectively, including $669 million and $174 million, respectively, for our newbuild construction projects.  The historical and
projected capital expenditures and non-cash capital additions for our ongoing newbuild construction projects were as follows:

(a)

In October 2022, we completed construction of the ultra-deepwater drillship Deepwater Atlas.  In June 2022, we borrowed $349 million
under  the  Shipyard  Loan  and  made  a  cash  payment  of  $46  million  to  satisfy  the  final  milestone  payment  due  upon  delivery  of
Deepwater Atlas.  We recorded the Shipyard Loan, net of imputed interest, and corresponding non-cash capital additions of $300 million.
 In October 2022, the rig commenced operations in the first of two phases using a 15,000 pounds per square inch blowout preventer.
 Before the start of the second phase, the rig will undergo installation of a 20,000 pounds per square inch blowout preventer and related
equipment, which is expected to be commissioned in the third quarter of 2023.

(b) Deepwater Titan is an ultra-deepwater drillship under construction.  In December 2022, we took delivery from Jurong Shipyard Pte Ltd.
in Singapore and borrowed $90 million under the Shipyard Loan and made a cash payment of $325 million to satisfy the final milestone
payment due upon delivery of Deepwater Titan.  We recorded the Shipyard Loan, net of imputed interest, and corresponding non-cash
capital additions of $82 million.  The rig is expected to commence operations under its drilling contract in the second quarter of 2023.
  The  projected  capital  additions  include  estimates  for  the  mobilization  and  customer  acceptance  in  the  U.S.  Gulf  of  Mexico  and  an
upgrade for two 20,000 pounds per square inch blowout preventers and other equipment required by our customer.

The ultimate amount of our capital expenditures is partly dependent upon financial market conditions, the actual level
of  operational  and  contracting  activity,  the  costs  associated  with  the  current  regulatory  environment  and  customer  requested
capital improvements and equipment for which the customer agrees to reimburse us.  As with any major shipyard project that
takes place over an extended period of time, the actual costs, the timing of expenditures and the project completion date may
vary  from  estimates  based  on  numerous  factors,  including  actual  contract  terms,  weather,  exchange  rates,  shipyard  labor
conditions, availability of suppliers to recertify equipment and the market demand for components and resources required for
drilling unit construction.  We intend to fund the cash requirements relating to our capital expenditures not financed under the
Shipyard Loans by using available cash balances, cash generated from operations and asset sales, borrowings under our Secured
Credit Facility and financing arrangements with banks or other capital providers.  Economic conditions and other factors could
impact the availability of these sources of funding.  See “—Sources and uses of liquidity.”

Dispositions—From time to time, we may also review the possible disposition of certain drilling assets.  Considering
market conditions, we have previously committed to plans to sell certain lower-specification drilling units for scrap value, and
we may identify additional lower-specification drilling units to be sold for scrap, recycling or alternative purposes.

RELATED PARTY TRANSACTIONS

We  engage  in  certain  related  party  transactions  with  our  unconsolidated  affiliates,  the  most  significant  of  which  are
under  agreements  with  Orion.    We  have  a  management  services  agreement  with  Orion  for  the  operation,  stacking  and
maintenance of the harsh environment floater Transocean Norge and a marketing services agreement for the marketing of the
rig.    We  also  periodically  lease  the  rig  under  short-term  bareboat  charter  agreements.    In  June  2021,  Orion  refinanced  its
shipyard  loans  under  a  financing  arrangement  for  $100  million,  in  which  we  made  a  cash  investment  of  $33  million.
 Borrowings under the financing arrangement are secured by Transocean Norge.  Additionally, we have a management services
agreement with Liquila for various services, including the marketing of

the  newbuild  ultra-deepwater  drilliship  Deepwater  Aquila.    See  Notes  to  Consolidated  Financial  Statements—Note  3—
Unconsolidated Affiliates.

In  August  2020,  Perestroika AS,  an  entity  affiliated  with  one  of  our  directors  that  beneficially  owns  approximately
11  percent  of  our  shares,  exchanged  $356  million  aggregate  principal  amount  of  the  0.50%  Exchangeable  Senior  Bonds  for
$213  million  aggregate  principal  amount  of  2.50%  Senior  Guaranteed  Exchangeable  Bonds.    Perestroika  AS  has  certain
registration  rights  related  to  its  shares  and  shares  that  may  be  issued  in  connection  with  any  exchange  of  its  2.50%  Senior
Guaranteed Exchangeable Bonds.  In November 2022, Perestroika AS made a cash investment of $10 million for a 13 percent
noncontrolling  ownership  interest  in  Liquila.    See  Notes  to  Consolidated  Financial  Statements—Note  3—Unconsolidated
Affiliates and Notes to Consolidated Financial Statements—Note 8—Debt.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Overview—We  prepare  our  consolidated  financial  statements  in  accordance  with  accounting  principles  generally
accepted  in  the  U.S.,  which  require  us  to  make  estimates  that  affect  the  reported  amounts  of  assets,  liabilities,  revenues,
expenses  and  related  disclosures  of  contingent  assets  and  liabilities.    These  estimates  require  significant  judgments  and
assumptions.    On  an  ongoing  basis,  we  evaluate  our  estimates,  including  those  related  to  our  income  taxes,  property  and
equipment, equity investments, contingencies, allowance for excess materials and supplies, intangibles, postemployment benefit
plans and share-based compensation.  We base our estimates on historical experience and on various other assumptions that we
believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying
amounts of assets and liabilities that are not readily apparent from other sources.  Actual results may differ from these estimates.

We  consider  the  following  to  be  our  critical  accounting  policies  and  estimates  since  they  are  very  important  to  the
portrayal of our financial condition and results and require our most subjective and complex judgments.  We have discussed the
development, selection and disclosure of such policies and estimates with the audit committee of our board of directors.  For a
discussion of our significant accounting policies and accounting standards updates, refer to our Notes to Consolidated Financial
Statements—Note 2—Significant Accounting Policies.

Income  taxes—We  provide  for  income  taxes  based  on  expected  taxable  income,  statutory  rates,  tax  laws  and  tax
planning  opportunities  available  to  us  in  the  jurisdictions  in  which  we  operate  or  have  a  taxable  presence.    The  relationship
between our provision for or benefit from income taxes and our income or loss before income taxes can vary significantly from
period to period considering, among other factors, (a) the overall level of income before income taxes, (b) changes in the blend
of income that is taxed based on gross revenues rather than income before taxes, (c) rig movements between taxing jurisdictions
and (d) our rig operating structures.  Consequently, our income tax expense does not change proportionally with our income or
loss before income taxes.

Uncertain tax positions—We apply significant judgment to evaluate our tax positions based on the interpretation of tax
laws  in  various  jurisdictions  and  with  the  use  of  estimates  and  assumptions  regarding  significant  future  events,  such  as  the
amount, timing and character of income, deductions and tax credits.  Our tax liability in any given year could be affected by
changes  in  tax  laws,  regulations,  agreements,  and  treaties,  currency  exchange  restrictions  or  our  level  or  profitability  of
operations  in  each  jurisdiction.    The  tax  laws  relating  to  the  offshore  drilling  industry  in  certain  jurisdictions  in  which  we
operate are not well developed, requiring us to apply incremental judgment.  Although we employ the best information available
at  the  time  we  prepare  our  annual  tax  provision,  a  number  of  years  may  elapse  before  the  tax  liabilities  in  the  various
jurisdictions are ultimately determined.

We are undergoing examinations of our tax returns in a number of taxing jurisdictions for various years.  We review
our  liabilities  on  an  ongoing  basis  and,  to  the  extent  audits  or  other  events  cause  us  to  adjust  the  liabilities  accrued  in  prior
periods, we recognize those adjustments in the period of the event.  Our tax liabilities are dependent on numerous factors that
cannot be reasonably projected, including among others, the amount and nature of additional taxes potentially asserted by local
tax  authorities;  the  willingness  of  local  tax  authorities  to  negotiate  a  fair  settlement  through  an  administrative  process;  the
impartiality  of  the  local  courts;  and  the  potential  for  changes  in  the  taxes  paid  to  one  country  that  either  produce,  or  fail  to
produce, offsetting tax changes in other countries.  Consequently, we cannot reasonably estimate the future impact of changes to
the assumptions and estimates related to our annual tax provision.

Unrecognized  tax  benefits—We  establish  liabilities  for  estimated  tax  exposures,  and  the  provisions  and  benefits
resulting  from  changes  to  those  liabilities  are  included  in  our  annual  tax  provision  along  with  related  interest  and  penalties.
  Such  tax  exposures  include  potential  challenges  to  permanent  establishment  positions,  intercompany  pricing,  disposition
transactions, and withholding tax rates and their applicability.  These exposures may be affected by changes in applicable tax
law or other factors, which could cause us to revise our prior estimates, and are generally resolved through the settlement of
audits within these tax jurisdictions or by judicial means.  At December 31, 2022 and 2021, we had unrecognized tax benefits of
$471  million  and  $435  million,  respectively,  including  interest  and  penalties,  against  which  we  recorded  net  operating  loss
deferred tax assets of $383 million and $320 million, respectively, resulting in net unrecognized tax benefits of $88 million and
$115 million, respectively, including interest and penalties, that upon reversal would favorably impact our effective tax rate.

Valuation allowance—We  apply  significant  judgment  to  determine  whether  our  deferred  tax  assets  will  be  fully  or
partially realized.  Our evaluation requires us to consider all available positive and negative evidence, including projected future
taxable  income  and  the  existence  of  cumulative  losses  in  recent  years.    We  continually  evaluate  tax  planning  strategies  that
could allow for the future utilization of

- 37 -

Table of Contents

our deferred tax assets.  When it is estimated to be more likely than not that all or some portion of certain deferred tax assets,
such as foreign tax credit carryovers or net operating loss carryforwards, will not be realized, we establish a valuation allowance
for the amount of the deferred tax assets that is considered to be unrealizable.  During the years ended December 31, 2022 and
2021,  in  connection  with  our  evaluation  of  the  projected  realizability  of  our  deferred  tax  assets,  we  determined  that  our
consolidated  cumulative  loss  incurred  over  the  recent  three-year  period  has  limited  our  ability  to  consider  other  subjective
evidence, such as projected contract activity rather than contract backlog.  See Notes to Consolidated Financial Statements—
Note 10—Income Taxes.

Property  and  equipment—We  apply  significant  judgment  to  account  for  our  property  and  equipment,  consisting
primarily  of  offshore  drilling  rigs  and  related  equipment,  related  to  estimates  and  assumptions  for  cost  capitalization,  useful
lives  and  salvage  values.    At  December  31,  2022  and  2021,  the  carrying  amount  of  our  property  and  equipment  was
$17.47 billion and $17.10 billion, respectively, representing 85 percent and 83 percent, respectively, of our total assets.

Capitalized costs—We capitalize costs incurred to enhance, improve and extend the useful lives of our property and
equipment  and  expense  costs  incurred  to  repair  and  maintain  the  existing  condition  of  our  rigs.    For  newbuild  construction
projects, we also capitalize the initial preparation, mobilization and commissioning costs incurred until the drilling unit is placed
into service.  Capitalized costs increase the carrying amounts of, and depreciation expense for, the related assets, which also
impact our results of operations.

Useful lives and salvage values—We depreciate our assets using the straight-line method over their estimated useful
lives after allowing for salvage values.  We estimate useful lives and salvage values by applying judgments and assumptions
that  reflect  both  historical  experience  and  expectations  regarding  future  operations,  rig  utilization  and  asset  performance.
 Useful lives and salvage values of rigs are difficult to estimate due to a variety of factors, including (a) technological advances
that impact the methods or cost of oil and gas exploration and development, (b) changes in market or economic conditions and
(c) changes in laws or regulations affecting the drilling industry.  Applying different judgments and assumptions in establishing
the useful lives and salvage values would likely result in materially different net carrying amounts and depreciation expense for
our  assets.    We  reevaluate  the  remaining  useful  lives  and  salvage  values  of  our  rigs  when  certain  events  occur  that  directly
impact the useful lives and salvage values of the rigs, including changes in operating condition, functional capability and market
and economic factors.  We may also consider major capital upgrades required to perform certain contracts and the long-term
impact of those upgrades on future marketability.  At December 31, 2022, a hypothetical one-year increase in the useful lives of
all of our rigs would cause a decrease in our annual depreciation expense of approximately $38 million and a hypothetical one-
year decrease would cause an increase in our annual depreciation expense of approximately $13 million.

Long-lived  asset  impairment—We  review  our  property  and  equipment  for  impairment  when  events  or  changes  in
circumstances  indicate  that  the  carrying  amounts  of  our  assets  held  and  used  may  not  be  recoverable.    Potential  impairment
indicators  include  rapid  declines  in  commodity  prices  and  related  market  conditions,  declines  in  dayrates  or  utilization,
cancellations of contracts or credit concerns of multiple customers.  During periods of oversupply, we may idle or stack rigs for
extended periods of time or we may elect to sell certain rigs for scrap, which could be an indication that an asset group may be
impaired since supply and demand are the key drivers of rig utilization and our ability to contract our rigs at economical rates.
 Our rigs are mobile units, equipped to operate in geographic regions throughout the world and, consequently, we may mobilize
rigs from an oversupplied region to a more lucrative and undersupplied region when it is economical to do so.  Many of our
contracts generally allow our customers to relocate our rigs from one geographic region to another, subject to certain conditions,
and our customers utilize this capability to meet their worldwide drilling requirements.  Accordingly, our rigs are considered to
be interchangeable within classes or asset groups, and we evaluate impairment by asset group.  We consider our asset groups to
be ultra-deepwater floaters and harsh environment floaters.

We  assess  recoverability  of  assets  held  and  used  by  projecting  undiscounted  cash  flows  for  the  asset  group  being
evaluated.  When the carrying amount of the asset group is determined to be unrecoverable, we recognize an impairment loss,
measured as the amount by which the carrying amount of the asset group exceeds its estimated fair value.  To estimate the fair
value of each asset group, we apply a variety of valuation methods, incorporating income, market and cost approaches.  We may
weigh the approaches, under certain circumstances, when relevant data is limited, when results are inconclusive or when results
deviate significantly.  Our estimate of fair value generally requires us to use significant unobservable inputs, representative of
Level 3 fair value measurements, including assumptions related to the long-term future performance of our asset groups, such as
projected revenues and costs, dayrates, rig utilization and revenue efficiency.  These projections involve uncertainties that rely
on assumptions about demand for our services, future market conditions and technological developments.  Because our business
is  cyclical  in  nature,  the  results  of  our  impairment  testing  are  expected  to  vary  significantly  depending  on  the  timing  of  the
assessment  relative  to  the  business  cycle.   Altering  either  the  timing  of  or  the  assumptions  used  to  estimate  fair  value  and
significant  unanticipated  changes  to  the  assumptions  could  materially  alter  an  outcome  that  could  otherwise  result  in  an
impairment loss.  Given the nature of these evaluations and their application to specific asset groups and specific time periods, it
is not possible to reasonably quantify the impact of changes in these assumptions.  In the year ended December 31, 2020, we
recognized a loss of $31 million, which had no tax effect, associated with the impairment of the midwater floater asset group.
 See Notes to Consolidated Financial Statements—Note 6—Long-Lived Assets.

Equity-method investments and impairment—We review our equity-method investments for potential impairment
when events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable in the
near  term.    Such  circumstances  include  the  following:  (a)  evidence  we  are  unable  to  recover  the  carrying  amount  of  our
investment, (b) evidence that the investee is unable to sustain earnings that would justify the carrying amount or (c) the current
fair value of the investment is less than the carrying amount.  If an evaluation of such circumstances results in the determination
that an impairment that is other than temporary exists,

- 38 -

Table of Contents

we  recognize  an  impairment  loss,  measured  as  the  amount  by  which  the  carrying  amount  of  the  investment  exceeds  its
estimated fair value.  To estimate the fair value of the investment, we apply valuation methods that rely primarily on the income
and market approaches.  Our estimate of fair value generally requires us to use significant unobservable inputs, representative of
Level  3  fair  value  measurements,  including  assumptions  related  to  the  estimated  discount  rate  and  the  investee’s  long-term
future  operational  performance  factors,  such  as  projected  revenues  and  costs  and  market  factors,  including  demand  for  the
investee’s  industry,  services  and  product  lines.    Such  projections  involve  significant  uncertainties  and  require  significant
judgment.  In the years ended December 31, 2021 and 2020, we recognized a loss of $37 million and $59 million, respectively,
associated with an other-than-temporary impairment of the carrying amount of our equity-method investments.  See Notes to
Consolidated Financial Statements—Note 3—Unconsolidated Affiliates.

OTHER MATTERS

Regulatory matters

We occasionally receive inquiries from governmental regulatory agencies regarding our operations around the world,
including  inquiries  with  respect  to  various  tax,  environmental,  regulatory  and  compliance  matters.   To  the  extent  appropriate
under the circumstances, we investigate such matters, respond to such inquiries and cooperate with the regulatory agencies.  See
Notes to Consolidated Financial Statements—Note 12—Commitments and Contingencies.

Tax matters

We conduct operations through our various subsidiaries in countries throughout the world.  Each country has its own
tax regimes with varying nominal rates, deductions and tax attributes that are subject to changes resulting from new legislation,
interpretation or guidance.  From time to time, as a result of these changes, we may revise previously evaluated tax positions,
which could cause us to adjust our recorded tax assets and liabilities.  Tax authorities in certain jurisdictions are examining our
tax returns and, in some cases, have issued assessments.  We intend to defend our tax positions vigorously.  Although we can
provide  no  assurance  as  to  the  outcome  of  the  aforementioned  changes,  examinations  or  assessments,  we  do  not  expect  the
ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations;
however,  it  could  have  a  material  adverse  effect  on  our  consolidated  statement  of  cash  flows.    See  Notes  to  Consolidated
Financial Statements—Note 10—Income Taxes.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest  rate  risk—We  are  exposed  to  interest  rate  risk,  primarily  associated  with  our  long-term  debt,  including
current maturities.  The following table presents the scheduled installment amounts and related weighted-average interest rates
of  our  long-term  debt  instruments  by  contractual  maturity  date.    The  scheduled  installment  amounts  include  the  contractual
principal  and  interest  payments  resulting  from  previously  restructured  debt.    The  following  table  presents  information  as  of
December  31,  2022  for  each  of  the  five  years  in  the  period  ending  December  31,  2027  and  thereafter  (in  millions,  except
interest rate percentages):

At  December  31,  2022  and  2021,  the  fair  value  of  our  outstanding  debt  was  $6.41  billion  and  $5.66  billion,
respectively.    During  the  year  ended  December  31,  2022,  the  fair  value  of  our  debt  increased  by  $751  million  due  to  the
following:  (a)  an  increase  of  $469  million  due  to  changes  in  the  market  prices  of  our  outstanding  debt,  (b)  an  increase  of
$407 million due to borrowings under shipyard loans established to finance a portion of the final installments due upon delivery
of  Deepwater  Atlas  and  Deepwater  Titan  and  (c)  a  net  increase  of  $388  million  due  to  the  issuance  of  the  4.625%  Senior
Guaranteed  Exchangeable  Bonds  in  private  exchanges  for  a  portion  of  the  0.50%  Exchangeable  Senior  Bonds  and  the
7.25%  Senior  Notes  and  the  sale  of  new  securities,  partially  offset  by  (d)  a  decrease  of  $468  million  due  to  scheduled
repayments and (e) a decrease of $44 million due to early retirement.  See Notes to Consolidated Financial Statements—Note 8
—Debt.

The  majority  of  our  cash  equivalents  is  subject  to  variable  interest  rates  or  short-term  interest  rates  and  such  cash

equivalents earn commensurately higher rates of return when interest rates increase.

Currency exchange rate risk—We are exposed to currency exchange rate risk primarily related to contract drilling
revenues,  employee  compensation  costs  and  purchasing  costs  that  are  denominated  in  currencies  other  than  our  functional
currency, the U.S. dollar.  We use a variety of techniques to minimize the exposure to currency exchange rate risk, including the
structuring of customer contract payment terms and occasional use of forward exchange contracts.  Our primary tool to manage
currency  exchange  rate  risk  involves  structuring  customer  contracts  to  provide  for  payment  in  both  U.S.  dollars  and  local
currency.    The  payment  portion  denominated  in  local  currency  is  based  on  anticipated  local  currency  requirements  over  the
contract term.  Due to various factors, including customer acceptance, local banking laws, national content requirements, other
statutory  requirements,  local  currency  convertibility,  local  inflation  and  revenue  efficiency,  actual  local  currency  needs  may
vary from those realized in the customer contracts, resulting in partial exposure to currency exchange rate risk.  The currency
exchange effect resulting from our international operations generally has not had a material impact on our operating results.  See
Notes to Consolidated Financial Statements—Note 18—Risk Concentration.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Management’s Report on Internal Control Over Financial Reporting

Management of Transocean Ltd. (the “Company,” “we” or “our”) is responsible for the integrity and objectivity of the
financial information included in this annual report.  We have prepared our financial statements in accordance with accounting
principles  generally  accepted  in  the  United  States,  which  require  us  to  apply  our  best  judgement  to  make  estimates  and
assumptions  for  certain  amounts.    We  are  responsible  for  establishing  and  maintaining  a  system  of  internal  controls  and
procedures  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  the
consolidated  financial  statements.    Our  internal  control  system  is  supported  by  a  program  of  internal  audits  and  appropriate
reviews  by  management,  written  policies  and  guidelines,  careful  selection  of  qualified  personnel,  and  a  written  Code  of
Integrity.  Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements
and,  even  when  determined  to  be  effective,  can  only  provide  reasonable  assurance  with  respect  to  financial  statement
preparation and presentation.  Also, projections of any evaluation of effectiveness in 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.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial
reporting as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934.  Management assessed the
effectiveness of the Company’s internal control over financial reporting as of December 31, 2022.  In making this assessment,
management  used  the  criteria  set  forth  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission,  as
described in Internal  Control-Integrated  Framework,  as  published  in  2013.    Based  on  this  assessment,  management  believes
that the Company maintained effective internal control over financial reporting as of December 31, 2022.

The Company’s independent auditors, Ernst & Young LLP, a registered public accounting firm, are appointed by the
audit  committee  of  the  Company’s  board  of  directors,  subject  to  ratification  by  our  shareholders.    Ernst  &  Young  LLP  has
audited and reported on the consolidated financial statements of Transocean Ltd. and subsidiaries, and the Company’s internal
control over financial reporting.  The reports of the independent auditors are contained in this annual report.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Transocean Ltd.

Opinion on Internal Control Over Financial Reporting

We have audited Transocean Ltd. and subsidiaries’ internal control over financial reporting as of December 31, 2022, based on
criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the
Treadway Commission (2013 framework) (the COSO criteria).  In our opinion, Transocean Ltd. and subsidiaries (the Company)
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the
COSO criteria.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, and the related consolidated
statements  of  operations,  comprehensive  loss,  equity  and  cash  flows  for  each  of  the  three  years  in  the  period  ended
December 31, 2022, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated
February 22, 2023 expressed an unqualified opinion thereon.

Basis for Opinion

The  Company’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report
on Internal Control Over Financial Reporting.  Our responsibility is to express an opinion on the Company’s internal control
over financial reporting based on our audit.  We are a public accounting firm registered with the PCAOB and are required to be
independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the
audit  to  obtain  reasonable  assurance  about  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all
material respects.

Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and
performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances.    We  believe  that  our  audit  provides  a
reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and
expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the
company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or
disposition of the company’s assets that could have a material effect on the financial statements.

Because  of  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 Shareholders and the Board of Directors of Transocean Ltd.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Transocean  Ltd.  and  subsidiaries  (the  Company)  as  of
December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive loss, equity and cash flows for
each of the three years in the period ended December 31, 2022, and the related notes and financial statement schedule listed in
the  Index  at  Item  15(a)  (collectively  referred  to  as  the  consolidated  financial  statements).    In  our  opinion,  the  consolidated
financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  at  December  31,  2022  and
2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in
conformity with U.S. generally accepted accounting principles.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)
(PCAOB),  the  Company's  internal  control  over  financial  reporting  as  of  December  31,  2022,  based  on  criteria  established  in
Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission
(2013 framework) and our report dated February 22, 2023, expressed an unqualified opinion thereon.

Opinion on the Financial Statements

These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on
the Company’s financial statements based on our audits.  We are a public accounting firm registered with the PCAOB and are
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to
error  or  fraud.    Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.    Such  procedures  included
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.  Our audits also included
evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall
presentation of the financial statements.  We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that
was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that
are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex  judgments.    The
communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken
as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit
matter or on the account or disclosure to which it relates.

Description of the
Matter

Income Taxes

As  discussed  in  Notes  2  and  10  to  the  consolidated  financial  statements,  the  Company  operates  in
multiple  jurisdictions  through  a  complex  operating  structure  and  is  subject  to  applicable  tax  laws,
treaties  or  regulations  in  each  jurisdiction  where  it  operates.   The  Company’s  provision  for  income
taxes is based on the tax laws and rates applicable in each jurisdiction.  The Company recognizes tax
benefits  they  believe  are  more  likely  than  not  to  be  sustained  upon  examination  by  the  taxing
authorities based on the technical merits of the position.

Auditing management’s provision for income taxes and related deferred taxes was complex because
of the Company’s multi-national operating structure.  In addition, a higher degree of auditor judgment
was  required  to  evaluate  the  Company’s  deferred  tax  provision  as  a  result  of  the  Company’s
interpretation of tax law in certain jurisdictions across its multiple subsidiaries.

Table of Contents

How We Addressed
the Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls
over the Company’s income tax provision process, including controls over management’s review of
the identification and valuation of deferred income taxes and changes in tax laws and regulations that
may impact the Company’s deferred income tax provision.

Our audit procedures also included, among others, (i) obtaining an understanding of the Company’s
overall tax structure, evaluating changes in the Company’s tax structure that occurred during the year
as  well  as  changes  in  tax  law,  and  assessing  the  interpretation  of  those  changes  under  the  relevant
jurisdiction’s  tax  law;  (ii)  utilizing  tax  resources  with  appropriate  knowledge  of  local  jurisdictional
laws  and  regulations;  (iii)  evaluating  the  completeness  and  accuracy  of  deferred  income  taxes,  and
(iv)  assessing  the  reasonableness  of  the  Company’s  valuation  allowance  on  deferred  tax  assets,
including  projections  of  taxable  income  from  the  future  reversal  of  existing  taxable  temporary
differences.

NOTE 1—BUSINESS

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,”
“we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas  wells.    As  of
December 31, 2022, we owned or had partial ownership interests in and operated a fleet of 38 mobile offshore drilling units,
consisting of 28 ultra-deepwater floaters and 10 harsh environment floaters.  As of December 31, 2022, we were constructing
one ultra-deepwater drillship and held a noncontrolling ownership interest in a company that is constructing one ultra-deepwater
drillship.

We  provide,  as  our  primary  business,  contract  drilling  services  in  a  single  operating  segment,  which  involves
contracting  our  mobile  offshore  drilling  rigs,  related  equipment  and  work  crews  to  drill  oil  and  gas  wells.   We  specialize  in
technically  demanding  regions  of  the  global  offshore  drilling  business  with  a  particular  focus  on  ultra-deepwater  and  harsh
environment  drilling  services.    Our  drilling  fleet  is  one  of  the  most  versatile  fleets  in  the  world,  consisting  of  drillships  and
semisubmersible floaters used in support of offshore drilling activities and offshore support services on a worldwide basis.

We  perform  contract  drilling  services  by  deploying  our  high-specification  fleet  in  a  single,  global  market  that  is
geographically dispersed in oil and gas exploration and development areas throughout the world.  The location of our rigs and
the allocation of our resources to build or upgrade rigs are determined by the activities and needs of our customers.

NOTE 2—SIGNIFICANT ACCOUNTING POLICIES

Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted
in the United States (“U.S.”), we must make judgments by applying estimates and assumptions that affect the reported amounts
of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities.  On an ongoing basis, we
evaluate  our  estimates  and  assumptions,  including  those  related  to  our  income  taxes,  property  and  equipment,  equity
investments, contingencies, allowance for excess materials and supplies, intangibles, postemployment benefit plans and share-
based  compensation.    We  base  our  estimates  and  assumptions  on  historical  experience  and  other  factors  that  we  believe  are
reasonable.  Actual results could differ from such estimates.

Fair value measurements—We estimate fair value at an exchange price that would be received to sell an asset or paid
to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between
market participants.  Our valuation techniques require inputs that we categorize using a three-level hierarchy, from highest to
lowest level of observable inputs, as follows: (1) significant observable inputs, including unadjusted quoted prices for identical
assets or liabilities in active markets (“Level 1”), (2) significant other observable inputs, including direct or indirect market data
for  similar  assets  or  liabilities  in  active  markets  or  identical  assets  or  liabilities  in  less  active  markets  (“Level  2”)  and
(3) significant unobservable inputs, including those that require considerable judgment for which there is little or no market data
(“Level 3”).  When a valuation requires multiple input levels, we categorize the entire fair value measurement according to the
lowest level of input that is significant to the measurement even though we may have also utilized significant inputs that are
more readily observable.

Consolidation—We consolidate entities in which we have a majority voting interest and entities that meet the criteria
for  variable  interest  entities  for  which  we  are  deemed  to  be  the  primary  beneficiary  for  accounting  purposes.    We  eliminate
intercompany transactions and accounts in consolidation.  We apply the equity method of accounting for an equity investment in
an unconsolidated entity if we have the ability to exercise significant influence over the entity that (a) does not meet the variable
interest  entity  criteria  or  (b)  meets  the  variable  interest  entity  criteria,  but  for  which  we  are  not  deemed  to  be  the  primary
beneficiary.  We measure other equity investments at fair value if the investment has a fair value that is readily determinable;
otherwise, we measure the investment at cost, less any impairment.  We separately present within equity on our consolidated
balance sheets the ownership interests attributable to parties with noncontrolling interests in our consolidated subsidiaries, and
we  separately  present  net  income  attributable  to  such  parties  on  our  consolidated  statements  of  operations.    See  Note  3—
Unconsolidated Affiliates and Note 13—Equity.

Revenues  and  related  pre-operating  costs—We  recognize  revenues  earned  under  our  drilling  contracts  based  on
variable dayrates, which range from a full operating dayrate to lower rates or zero rates for periods when drilling operations are
interrupted or restricted, based on the specific activities we perform during the contract on an hourly, or more frequent, basis.
 Such dayrate consideration is attributed to the distinct time period to which it relates within the contract term, and therefore, is
recognized as we perform the services.  When the operating dayrate declines over the contract term, we recognize revenues on a
straight-line basis over the estimated contract period.  We recognize reimbursement revenues and the corresponding costs as we
provide  the  customer-requested  goods  and  services,  when  such  reimbursable  costs  are  incurred  while  performing  drilling
operations.    Prior  to  performing  drilling  operations,  we  may  receive  pre-operating  revenues,  on  either  a  fixed  lump-sum  or
variable  dayrate  basis,  for  mobilization,  contract  preparation,  customer-requested  goods  and  services  or  capital  upgrades,  for
which we record a contract liability and recognize as revenues on a straight-line basis over the estimated contract period.  We
recognize  losses  for  loss  contracts  as  such  losses  are  incurred.    We  recognize  revenues  for  demobilization  over  the  contract
period  unless  otherwise  constrained.   We  recognize  revenues  from  contract  terminations  as  we  fulfill  our  obligations  and  all
contingencies  have  been  resolved.    We  apply  the  optional  exemption  that  permits  us  to  exclude  disclosure  of  the  estimated
transaction price related to the variable portion of unsatisfied performance obligations at the end of the reporting period, as our
transaction price is

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

typically  based  on  a  single  performance  obligation  consisting  of  a  series  of  distinct  hourly,  or  more  frequent,  periods,  the
variability of which will be resolved at the time of the future services.

To obtain contracts with our customers, we incur pre-operating costs to prepare a rig for contract and mobilize a rig to
the drilling location.  We defer such pre-operating contract preparation and mobilization costs for recognition in operating and
maintenance costs over the estimated contract period on a straight-line basis, consistent with the general pace of activity.  See
Note 4—Revenues.

Contract intangible assets—We recognize contract intangible assets related to acquired executory contracts, such as
drilling  contracts.    The  drilling  contract  intangible  assets  represent  the  amount  by  which  the  fixed  dayrates  of  the  acquired
contracts  were  above  the  market  dayrates  that  were  available  or  expected  to  be  available  during  the  term  of  the  contract  for
similar contracts, measured as of the acquisition date.  We amortize the carrying amount of the drilling contract intangible assets
using  the  straight-line  method  as  a  reduction  of  contract  drilling  revenues  over  the  expected  remaining  contract  period.    See
Note 5—Contract Intangible Assets.

Share-based compensation—To measure the fair values of granted or modified service-based restricted share units,
we use the market price of our shares on the grant date or modification date.  To measure the fair values of granted or modified
stock  options,  we  use  the  Black-Scholes-Merton  option-pricing  model  and  apply  assumptions  for  the  expected  life,  risk-free
interest  rate,  expected  volatility  and  dividend  yield.    To  measure  the  fair  values  of  granted  or  modified  performance-based
restricted  share  units  subject  to  market  factors,  we  use  a  Monte  Carlo  simulation  model  and,  in  addition  to  the  assumptions
applied  for  the  Black-Scholes-Merton  option-pricing  model,  we  use  a  risk  neutral  approach  and  an  average  price  at  the
performance  start  date.    To  measure  the  fair  values  of  granted  or  modified  performance-based  restricted  share  units  that  are
subject to performance targets, we use the market price of our shares on the grant date or modification date adjusted for the
projected  performance  rate  expected  to  be  achieved  at  the  end  of  the  measurement  period.    We  recognize  share-based
compensation expense in the same financial statement line item as cash compensation paid to the respective employees or non-
employee directors.  We recognize such compensation expense on a straight-line basis over the service period through the date
the employee or non-employee director is no longer required to provide service to earn the award.  See Note 14—Share-Based
Compensation.

Capitalized interest—We capitalize interest costs for qualifying construction and upgrade projects and only capitalize
interest  costs  during  periods  in  which  progress  for  the  construction  projects  continues  to  be  underway.    In  the  years  ended
December 31, 2022, 2021 and 2020, we capitalized interest costs of $73 million, $50 million and $47 million, respectively, for
our construction work in progress.

Functional currency—We  consider  the  U.S.  dollar  to  be  the  functional  currency  for  all  of  our  operations  since  the
majority of our revenues and expenditures are denominated in U.S. dollars, which limits our exposure to currency exchange rate
fluctuations.  We recognize currency exchange rate gains and losses in other, net.  In the years ended December 31, 2022, 2021
and 2020, we recognized a net loss of $8 million, $1 million and $8 million, respectively, related to currency exchange rates.

Income  taxes—We  provide  for  income  taxes  based  on  expected  taxable  income,  statutory  rates,  tax  laws  and  tax
planning opportunities available to us in the jurisdictions in which we operate or have a taxable presence.  We recognize the
effect of changes in tax laws as of the date of enactment.  We recognize potential global intangible low-taxed income inclusions
as a period cost.

We maintain liabilities for estimated tax exposures in our jurisdictions of operation, and we recognize the provisions
and  benefits  resulting  from  changes  to  those  liabilities  in  our  income  tax  expense  or  benefit  along  with  related  interest  and
penalties.  Income tax exposure items include potential challenges to permanent establishment positions, intercompany pricing,
disposition transactions, and withholding tax rates and their applicability.  These tax exposures are resolved primarily through
the settlement of audits within these tax jurisdictions or by judicial means, but can also be affected by changes in applicable tax
law or other factors, which could cause us to revise past estimates.

We measure deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the deferred
tax  assets  and  liabilities  are  expected  to  be  recovered  or  paid.    In  evaluating  our  ability  to  realize  deferred  tax  assets,  we
consider all available positive and negative evidence, including projected future taxable income and the existence of cumulative
losses in recent years.  We record a valuation allowance for deferred tax assets when it is more likely than not that some or all of
the benefit from the deferred tax asset will not be realized.  For example, we may record a valuation allowance for deferred tax
assets resulting from net operating losses incurred during the year in certain jurisdictions for which the benefit of the losses will
not be realized or for foreign tax credit carryforwards that may expire prior to their utilization.  See Note 10—Income Taxes.

Cash  and  cash  equivalents—We  consider  cash  equivalents  to  include  highly  liquid  debt  instruments  with  original
maturities of three months or less, such as time deposits with commercial banks that have high credit ratings, U.S. Treasury and
government securities, Eurodollar time deposits, certificates of deposit and commercial paper.  We may also invest excess funds
in  no-load,  open-ended,  management  investment  trusts.    Such  management  trusts  invest  exclusively  in  high-quality  money
market instruments.

Restricted cash and cash equivalents—We maintain restricted cash and cash equivalents that are either pledged for
debt  service  under  certain  bond  indentures,  as  required  under  certain  bank  credit  arrangements,  or  held  in  accounts  that  are
subject  to  restrictions  due  to  legislation,  regulation  or  court  order.    We  classify  such  restricted  cash  and  cash  equivalents  in
current assets if the restriction is expected to expire or otherwise be resolved within one year or if such funds are considered to
offset  liabilities  that  are  properly  classified  as  current  liabilities.  See  Note  8—Debt  and  Note  12—Commitments  and
Contingencies.

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

Materials and supplies—We record materials and supplies at their average cost less an allowance for excess items.
 We estimate the allowance for excess items based on historical experience and expectations for future use of the materials and
supplies.  During the year ended December 31, 2021, we identified certain materials and supplies that were in excess of our
expected  future  usage  based  on  our  current  market  outlook,  and  as  a  result  of  these  items,  we  increased  our  allowance  by
$28  million  ($0.04  per  diluted  share,  net  of  tax).    At  December  31,  2022  and  2021,  our  allowance  for  excess  items  was
$199 million and $183 million, respectively.

Assets held for sale—We classify an asset as held for sale when the facts and circumstances meet the criteria for such
classification, including the following: (a) we have committed to a plan to sell the asset, (b) the asset is available for immediate
sale,  (c)  we  have  initiated  actions  to  complete  the  sale,  including  locating  a  buyer,  (d)  the  sale  is  expected  to  be  completed
within one year, (e) the asset is being actively marketed at a price that is reasonable relative to its fair value, and (f) the plan to
sell is unlikely to be subject to significant changes or termination.  At December 31, 2022 and 2021, we had no assets classified
as held for sale.

Property  and  equipment—We  apply  judgment  to  account  for  our  property  and  equipment,  consisting  primarily  of
offshore  drilling  rigs  and  related  equipment,  related  to  estimates  and  assumptions  for  cost  capitalization,  useful  lives  and
salvage  values.    We  base  our  estimates  and  assumptions  on  historical  experience  and  expectations  regarding  future  industry
conditions and operations.  At December 31, 2022, the aggregate carrying amount of our property and equipment represented
approximately 85 percent of our total assets.

We capitalize expenditures for newbuilds, renewals, replacements and improvements, including capitalized interest, if
applicable, and we recognize the expense for maintenance and repair costs as incurred.  For newbuild construction projects, we
also  capitalize  the  initial  preparation,  mobilization  and  commissioning  costs  incurred  until  the  drilling  unit  is  placed  into
service.  Upon sale or other disposition of an asset, we recognize a net gain or loss on disposal of the asset, which is measured
as the difference between the net carrying amount of the asset and the net proceeds received.  We compute depreciation using
the straight-line method after allowing for salvage values.

The estimated original useful life of our drilling units is 35 years, our buildings and improvements range from three to
30 years and our machinery and equipment range from four to 20 years.  We reevaluate the remaining useful lives and salvage
values  of  our  rigs  when  certain  events  occur  that  directly  impact  the  useful  lives  and  salvage  values  of  the  rigs,  including
changes in operating condition, functional capability and market and economic factors.  When evaluating the remaining useful
lives of rigs, we also consider major capital upgrades required to perform certain contracts and the long-term impact of those
upgrades on future marketability.

Long-lived  asset  impairment—We  review  the  carrying  amounts  of  long-lived  assets,  including  property  and
equipment and right-of-use assets, for potential impairment when events occur or circumstances change that indicate that the
carrying amount of such assets may not be recoverable.  For assets classified as held and used, we determine recoverability by
evaluating the estimated undiscounted future net cash flows based on projected dayrates and utilization of the asset group under
review.  We consider our asset groups to be ultra-deepwater floaters and harsh environment floaters.  When an impairment of
one or more of our asset groups is indicated, we measure the impairment as the amount by which the asset group’s carrying
amount  exceeds  its  estimated  fair  value.   We  measure  the  fair  values  of  our  asset  groups  by  applying  a  variety  of  valuation
methods,  incorporating  a  combination  of  income,  market  and  cost  approaches,  using  projected  discounted  cash  flows  and
estimates of the exchange price that would be received for the assets in the principal or most advantageous market for the assets
in an orderly transaction between market participants as of the measurement date.  For an asset classified as held for sale, we
consider the asset to be impaired to the extent its carrying amount exceeds its estimated fair value less cost to sell.  See Note 6
—Long-Lived Assets.

Equity investments and impairment—We review our equity-method investments, and other equity investments for
which  a  readily  determinable  fair  value  is  not  available,  for  potential  impairment  when  events  or  changes  in  circumstances
indicate  that  the  carrying  amount  of  the  investment  might  not  be  recoverable  in  the  near  term.    If  we  determine  that  an
impairment that is other than temporary exists, we recognize an impairment loss, measured as the amount by which the carrying
amount  of  the  investment  exceeds  its  estimated  fair  value.   To  estimate  the  fair  value  of  the  investment,  we  apply  valuation
methods  that  rely  primarily  on  the  income  and  market  approaches.    In  the  years  ended  December  31,  2021  and  2020,  we
recognized  a  loss  of  $37  million  and  $62  million,  respectively,  associated  with  the  other-than-temporary  impairment  of  the
carrying amount of our equity investments.  We amortize the basis difference caused by such impairments using the straight-line
method over the estimated life of the asset.  See Note 3—Unconsolidated Affiliates.

Pension  and  other  postemployment  benefit  plans—We  use  a  measurement  date  of  January  1  for  determining  net
periodic  benefit  costs  and  December  31  for  determining  plan  benefit  obligations  and  the  fair  values  of  plan  assets.    We
determine  our  net  periodic  benefit  costs  based  on  a  market-related  value  of  assets  that  reduces  year-to-year  volatility  by
including  investment  gains  or  losses  subject  to  amortization  over  a  five-year  period  from  the  year  in  which  they  occur.   We
calculate investment gains or losses for this purpose as the difference between the expected return calculated using the market-
related value of assets and the actual return based on the market-related value of assets.  If gains or losses exceed 10 percent of
the greater of plan assets or plan liabilities, we amortize such gains or losses over the average expected future service period of
the employee participants.

We  measure  the  actuarially  determined  obligations  and  related  costs  for  our  defined  benefit  pension  and  other
postemployment  benefit  plans,  retiree  life  insurance  and  medical  benefits,  by  applying  assumptions,  the  most  significant  of
which include long-term rate of return on plan assets, discount rates and mortality rates.  For the long-term rate of return, we
develop our assumptions regarding the expected rate of return on plan assets based on historical experience and projected long-
term investment returns, and we weight the assumptions

- 51 -

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

based on each plan’s asset allocation.  For the discount rate, we base our assumptions on a yield curve approach using Aa-rated
corporate bonds and the expected timing of future benefit payments.  At December 31, 2022 and 2021, the funded status of our
pension  and  other  postemployment  benefit  plans  represented  an  aggregate  liability  of  $174  million  and  $132  million,
respectively, and an aggregate asset of $44 million and $102 million, respectively.  See Note 9—Postemployment Benefit Plans.

Contingencies—We assess our contingencies on an ongoing basis to evaluate the appropriateness of our liabilities and
disclosures for such contingencies.  We establish liabilities for estimated loss contingencies when we believe a loss is probable
and  the  amount  of  the  probable  loss  can  be  reasonably  estimated.    Once  established,  we  adjust  the  carrying  amount  of  a
contingent  liability  upon  the  occurrence  of  a  recognizable  event  when  facts  and  circumstances  change,  altering  our  previous
assumptions with respect to the likelihood or amount of loss.  We recognize corresponding assets for those loss contingencies
that we believe are probable of being recovered through insurance.  We recognize expense for legal costs as they are incurred,
and  we  recognize  a  corresponding  asset  for  such  legal  costs  only  if  we  expect  such  legal  costs  to  be  recovered  through
insurance.

NOTE 3—UNCONSOLIDATED AFFILIATES

Equity investments

Overview—We  hold  noncontrolling  equity  investments  in  various  unconsolidated  companies,  including  (a)  our
33 percent ownership interest in Orion Holdings (Cayman) Limited (together with its subsidiary, “Orion”), a Cayman Islands
company  that  owns  the  harsh  environment  floater  Transocean  Norge,  (b)  our  20  percent  ownership  interest  in  Liquila
Ventures  Ltd.  (together  with  its  subsidiaries,  “Liquila”),  a  Bermuda  company  formed  to  construct,  own  and  operate  the
newbuild  ultra-deepwater  drillship  Deepwater  Aquila,  (c)  our  20  percent  ownership  interest  in  Nauticus  Robotics,  Inc.,  a
publicly traded company that develops highly sophisticated, ultra-sustainable marine robots and intelligent software to power
them, (d) our interests in Ocean Minerals LLC, the parent company of Moana Minerals Ltd., a Cook Islands subsea resource
development company that intends to explore and extract polymetallic nodules, and (e) our interests in certain other companies
that  are  involved  in  researching  and  developing  technology  to  improve  efficiency,  reliability,  sustainability  and  safety  for
drilling and other activities.  In the years ended December 31, 2022, 2021 and 2020, we recognized a net loss of $24 million,
$10 million and $10 million, respectively, recorded in other income and expense, associated with equity in losses of our equity
investments.  At December 31, 2022 and 2021, the aggregate carrying amount of our equity investments was $113 million and
$91 million, respectively, recorded in other assets.

In  November  2022,  we  and  Perestroika  AS  (“Perestroika”),  an  entity  affiliated  with  one  of  our  directors  that
beneficially  owns  approximately  11  percent  of  our  shares,  each  made  a  cash  contribution  of  $15  million  and  $10  million,
respectively, to Liquila.  The investments represented proportionate contributions, together with a contribution from the holder
of the remaining 67 percent ownership interest, that were used to make the initial payment to the shipyard to acquire a newbuild
drillship for a purchase price of approximately $200 million.  We concluded that Liquila is a variable interest entity because its
equity at risk was insufficient to permit it to carry on its activities without additional subordinated financial support, and we
further concluded that we are not the primary beneficiary since the power to direct the activities that most significantly impact
its economic performance are jointly controlled.  The holder of the remaining 67 percent ownership interest in Liquila may, at
any time through November 10, 2023, elect to require us to repurchase up to 80 percent of such holder’s initial investment at the
value  that  the  holder  initially  paid  therefor.    We  may,  at  our  election,  settle  any  such  repurchase  by  delivering  cash,
Transocean Ltd. shares or a combination of cash and shares, where any shares delivered would be valued using the then-current
market price of shares.  At December 31, 2022, the carrying amount of our investment in Liquila was $15 million, recorded in
other assets.

Impairments—Our equity-method investment in Orion is the most significant of our equity investments.  In the years
ended December 31, 2021 and 2020, we recognized a loss of $37 million and $59 million, respectively, which had no tax effect,
recorded in other, net, associated with the impairment of our equity investment in Orion upon determination that the carrying
amount exceeded the estimated fair value and that the impairment was other than temporary.  We estimated the fair value of our
investment  by  applying  the  income  method  using  significant  unobservable  inputs,  representative  of  Level  3  fair  value
measurements,  including  an  assumed  discount  rate  of  12  percent  and  assumptions  about  the  future  performance  of  the
investment, such as future demand and supply for harsh environment floaters, rig utilization, revenue efficiency and dayrates.
  At  December  31,  2022  and  2021,  the  aggregate  carrying  amount  of  our  equity  investment  in  Orion  was  $54  million  and
$57 million, respectively.

Related party transactions—We  engage  in  certain  related  party  transactions  with  our  unconsolidated  affiliates,  the
most  significant  of  which  are  under  agreements  with  Orion.    We  operate,  stack  and  maintain  Transocean  Norge  under  a
management services agreement, and we market Transocean Norge under a marketing services agreement.  During operations,
we lease Transocean Norge under a short-term bareboat charter agreement, the next of which is expected to begin in May 2023
and expire in January 2024.  In addition to our ownership interest in Liquila, we maintain the exclusive right to market, and
once it is placed into service, manage the operations of the rig under a master services agreement.  Additionally, we procure and
provide  services  and  equipment  from  and  to  other  unconsolidated  affiliates  for  technological  innovation  and  subsea  minerals
exploration.

In  the  years  ended  December  31,  2022,  2021  and  2020,  we  received  an  aggregate  cash  payment  of  $40  million,
$16  million  and  $46  million,  respectively,  primarily  for  services  performed  under  the  management  services  agreement  with
Orion.  In the years ended

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

December  31,  2022,  2021  and  2020,  we  recognized  rent  expense  of  $11  million,  $12  million  and  $22  million,  respectively,
recorded in operating and maintenance costs, and made an aggregate cash payment of $10 million, $15 million and $22 million,
respectively, to charter the rig and rent other equipment from Orion.  In the years ended December 31, 2022, 2021 and 2020, we
made an aggregate cash payment of $7 million, $6 million and $15 million, respectively, to other unconsolidated affiliates for
research and development and for equipment to reduce emissions and improve reliability.

In June 2021, Orion refinanced its shipyard loans under a financing arrangement for $100 million, , and we made a
cash investment of $33 million in the loan facility.  The financing arrangement, which expires in June 2024, requires interest to
be paid on outstanding borrowings at the London Interbank Offered Rate plus a margin of 6.50 percent per annum.  Borrowings
under the financing arrangement are secured by Transocean Norge.  At December 31, 2022 and 2021, the aggregate principal
amount due to us under the various financing arrangements with our unconsolidated affiliates was $41 million and $36 million,
respectively, recorded in other assets.

Subsequent event

In  February  2023,  we  agreed  to  make  an  investment  for  a  noncontrolling  ownership  interest  in  Global  Sea  Mineral
Resources, a Belgian company and leading developer of nodule collection technology, which is engaged in the development and
exploration of deep-sea polymetallic nodules that contain metals critical to the growing renewable energy market.  In addition to
a cash investment of $10 million, we agreed to contribute the ultra-deepwater drillship Ocean Rig Olympia, and we expect to
contribute engineering services in the future.  In the three months ending March 31, 2023, we expect to recognize a material
loss associated with the contribution of the rig and related assets.

NOTE 4—REVENUES

Overview—We  earn  revenues  primarily  by  performing  the  following  activities:  (i)  providing  our  drilling  rig,  work
crews,  related  equipment  and  services  necessary  to  operate  the  rig  (ii)  delivering  the  drilling  rig  by  mobilizing  to  and
demobilizing from the drill location, and (iii) performing certain pre-operating activities, including rig preparation activities or
equipment modifications required for the contract.  These services represent a single performance obligation under most all of
our  drilling  contracts  with  customers  that  is  satisfied  over  time,  the  duration  of  which  varies  by  contract.   At  December  31,
2022,  the  drilling  contract  with  the  longest  expected  remaining  duration,  excluding  unexercised  options,  extends  through
July 2029.

Performance obligations satisfied in prior periods—In June 2020, we entered into a settlement and mutual release
agreement with a customer, which provided for the final settlement of disputes related to performance obligations satisfied in
prior periods.  In connection with the settlement, among other things, our customer agreed to pay us $185 million in four equal
installments  through  January  15,  2023.    In  the  year  ended  December  31,  2020,  we  recognized  revenues  of  $177  million,
representing  the  discounted  value  of  the  future  payments,  and  recorded  corresponding  accounts  receivable,  net  of  imputed
interest.    In  each  of  the  three  years  ended  December  31,  2022,  we  received  an  aggregate  cash  payment  of  $46  million  in
scheduled installments under the arrangement.  At December 31, 2022, the aggregate carrying amount of the related receivable
was  $46  million,  net  of  imputed  interest,  recorded  in  accounts  receivable.    At  December  31,  2021,  the  aggregate  carrying
amount of the related receivable was $90 million, net of imputed interest, including $46 million and $44 million, recorded in
accounts receivable and other assets, respectively.

Pre-operating costs—In the years ended December 31, 2022, 2021 and 2020, we recognized pre-operating costs of
$47 million, $48 million and $60 million, respectively, recorded in operating and maintenance costs.  At December 31, 2022
and 2021, the unrecognized pre-operating costs to obtain contracts was $26 million and $21 million, respectively, recorded in
other assets.

Because the majority of our assets are mobile, the geographic locations of such assets at the end of the periods are not
necessarily  indicative  of  the  geographic  distribution  of  the  operating  revenues  generated  by  such  assets  during  the  periods
presented.  Our international operations are subject to certain political and other uncertainties, including risks of war and civil
disturbances or other market disrupting events, expropriation of equipment, repatriation of income or capital, taxation policies,
and  the  general  hazards  associated  with  certain  areas  in  which  we  operate.    Although  we  are  organized  under  the  laws  of
Switzerland, we have minimal assets located in Switzerland, and we do not conduct any operations or earn operating revenues
in Switzerland.

Impairments of assets held and used—During the year ended December 31, 2020, we identified indicators that the
carrying  amounts  of  our  asset  groups  may  not  be  recoverable.    Such  indicators  included  significant  declines  in  commodity
prices and the market value of our stock, a reduction of expected demand for our drilling services as our customers announced
reductions  of  capital  investments  in  response  to  commodity  prices  and  a  reduction  of  projected  dayrates.   As  a  result  of  our
testing,  we  determined  that  the  carrying  amount  of  our  midwater  floater  asset  group  was  impaired.    In  the  year  ended
December 31, 2020, we recognized a loss of $31 million ($0.05 per diluted share), which had no tax effect, associated with the
impairment of our midwater floater asset group.  We estimated the fair value of the rig and related assets in this asset group by
applying  the  market  approach  using  significant  other  observable  inputs,  representative  of  Level  2  fair  value  measurements,
including the marketability of the rig and prices of comparable rigs that may be sold for scrap value.

Impairments  of  assets  held  for  sale—In  the  year  ended  December  31,  2020,  we  recognized  an  aggregate  loss  of
$556 million ($0.90 per diluted share), which had no tax effect, associated with the impairment of the ultra-deepwater floater
GSF Development Driller II, the harsh environment floaters Polar Pioneer and Songa Dee and the midwater floaters Sedco 711,
Sedco 714 and Transocean 712, along with related assets, which we determined were impaired at the time that we classified the
assets as held for sale.  We measured the impairment of the drilling units and related assets as the amount by which the carrying
amount  exceeded  the  estimated  fair  value  less  costs  to  sell.   We  estimated  the  fair  value  of  the  assets  using  significant  other
observable inputs, representative of Level 2 fair value measurements, including indicative market values for the drilling units
and related assets to be sold for scrap value or binding contracts to sell such assets for alternative purposes.  If we commit to
plans to sell additional rigs for values below the respective carrying amounts, we will be required to recognize additional losses
in future periods associated with the impairment of such assets.

Dispositions—During the year ended December 31, 2021, in connection with our efforts to dispose of non-strategic
assets,  we  completed  the  sale  of  the  harsh  environment  floater  Leiv  Eiriksson  and  related  assets.    During  the  year  ended
December 31, 2020, we completed the sale of the ultra-deepwater floater GSF Development Driller II, the harsh environment
floaters Polar Pioneer, Songa Dee and Transocean Arctic and the midwater floaters Sedco 711, Sedco 714 and Transocean 712,
along  with  related  assets.    In  the  years  ended  December  31,  2021  and  2020,  we  received  aggregate  net  cash  proceeds  of
$4  million  and  $20  million,  respectively,  and  recognized  an  aggregate  net  loss  of  $57  million  ($0.09  per  diluted  share)  and
$61 million ($0.10 per diluted share), which had no tax effect, primarily associated with the disposal of these rigs and related
assets.    In  the  years  ended  December  31,  2022,  2021  and  2020,  we  received  aggregate  net  cash  proceeds  of  $7  million,
$5  million  and  $4  million,  respectively  and  recognized  an  aggregate  net  loss  of  $10  million,  $5  million  and  $23  million,
respectively, associated with the disposal of assets unrelated to rig sales.

NOTE 7—LEASES

Overview—Our operating leases are principally for office space, storage facilities, operating equipment and land.  At
December 31, 2022, our operating leases had a weighted-average discount rate of 6.4 percent and a weighted-average remaining
lease term of 12.7 years.

Our  finance  lease  for  the  ultra-deepwater  drillship  Petrobras  10000  has  an  implicit  interest  rate  of  7.8  percent  and
requires scheduled monthly installments through the lease expiration in August 2029, after which we are obligated to acquire
the drillship from the lessor for one dollar.  We recognize expense for the amortization of the right-of-use asset in depreciation
and amortization.

in  right  of  payment  of  all  of  our  existing  and  future  unsecured  unsubordinated  obligations.    Such  notes  are  structurally  senior  to  the  Priority
Guaranteed Notes to the extent of the value of the assets of the subsidiaries guaranteeing the notes.

(f) The subsidiary borrowers under the Shipyard Loans and the subsidiary issuer of the registered notes are wholly owned indirect subsidiaries of

Transocean Inc.  The loans and notes are fully and unconditionally guaranteed by Transocean Inc.

Transocean  Ltd.  has  no  independent  assets  or  operations,  and  its  other  subsidiaries  not  owned  indirectly  through
Transocean Inc. are minor.  Transocean Inc. has no independent assets and operations, other than those related to its investments
in  non-guarantor  operating  companies  and  balances  primarily  pertaining  to  its  cash  and  cash  equivalents  and  debt.
 Transocean Ltd. and Transocean Inc. are not subject to any significant restrictions on their ability to obtain funds from their
consolidated subsidiaries by dividends, loans or capital distributions.

Indentures—The  indentures  that  govern  our  debt  generally  contain  covenants  that,  among  other  things,  limit  our
ability to incur certain liens on our drilling units without equally and ratably securing the notes, to engage in certain sale and
lease back transactions covering any of our drilling units, to allow our subsidiaries to incur certain additional debt, or to engage
in  certain  merger,  consolidation  or  reorganization  transactions  or  to  enter  into  a  scheme  of  arrangement  qualifying  as  an
amalgamation.

The indentures that govern the 0.50% exchangeable senior bonds due January 2023 (the “0.50% Exchangeable Senior
Bonds”), the 4.00% senior guaranteed exchangeable bonds due December 2025 (the “4.00% Senior Guaranteed Exchangeable
Bonds”),  the  2.50%  senior  guaranteed  exchangeable  bonds  due  January  2027  (the  “2.50%  Senior  Guaranteed  Exchangeable
Bonds”)  and  the  4.625%  senior  guaranteed  exchangeable  bonds  due  September  2029  (the  “4.625%  Senior  Guaranteed
Exchangeable Bonds”) require such bonds to be repurchased upon the occurrence of certain fundamental changes and events, at
specified prices depending on the particular fundamental change or event, which include changes and events related to certain
(i) change of control events applicable to Transocean Ltd. or Transocean Inc., (ii) the failure of our shares to be listed or quoted
on a national securities exchange and (iii) specified tax matters.

The indentures that govern the 5.375% Senior Secured Notes due May 2023 (the “5.375% Senior Secured Notes”), the
5.875%  senior  secured  notes  due  January  2024  (the  “5.875%  Senior  Secured  Notes”),  the  7.75%  senior  secured  notes  due
October  2024  (the  “7.75%  Senior  Secured  Notes”),  the  6.25%  senior  secured  notes  due  December  2024  (the  “6.25%  Senior
Secured  Notes”),  the  6.125%  senior  secured  notes  due  August  2025  (the  “6.125%  Senior  Secured  Notes”)  and  the
6.875% senior secured notes due February 2027 contain covenants that limit the ability of our subsidiaries that own or operate
the collateral rigs to declare or pay dividends to their affiliates.

The indentures that govern our senior secured notes contain certain lien requirements.  At December 31, 2022, we had
restricted  cash  and  cash  equivalents  of  $276  million  deposited  in  restricted  accounts  to  satisfy  debt  service  and  reserve
requirements for the senior secured notes.  At December 31, 2022, the rigs encumbered for the senior secured notes and our
including  Deepwater  Atlas,  Deepwater  Pontus,  Deepwater  Poseidon,  Deepwater  Proteus,
Shipyard  Loans, 
Deepwater  Thalassa,  Transocean  Enabler,  Transocean  Encourage  and  Transocean  Endurance,  had  an  aggregate  carrying
amount of $5.45 billion.  We will be required to redeem the senior secured notes at a price equal to 100 percent of the aggregate
principal amount without a make-whole premium, upon the occurrence of certain events related to the respective collateral rigs
and related drilling contracts.

Interest  rate  adjustments—The  interest  rates  for  the  7.35%  senior  notes  due  December  2041  (the  “7.35%  Senior
Notes”)  are  subject  to  adjustment  from  time  to  time  upon  a  change  to  the  credit  rating  of  our  non-credit  enhanced  senior
unsecured long-term debt.  At December 31, 2022, the interest rate in effect for the 7.35% Senior Notes was 9.35 percent.

Scheduled  maturities—At  December  31,  2022,  the  scheduled  maturities  of  our  debt,  including  the  principal
installments  and  other  installments,  representing  the  contractual  interest  payments  of  previously  restructured  debt,  were  as

Credit agreements

Secured Credit Facility—As of December 31, 2022, we have a secured revolving credit facility established under a
bank credit agreement (as amended from time to time, the “Secured Credit Facility”), which is scheduled to mature on June 22,
2025.  In July 2022, we amended the bank credit agreement for our Secured Credit Facility to, among other things, (i) extend
the maturity date from June 22, 2023

- 58 -

    
 
 
Table of Contents

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

to June 22, 2025, (ii) reduce the borrowing capacity from $1.33 billion to $774 million through June 22, 2023, and thereafter
reduce the borrowing capacity to $600 million through June 22, 2025 and (iii) replace our ability to borrow under the Secured
Credit Facility at the reserve adjusted London Interbank Offered Rate plus a margin (the “Secured Credit Facility Margin”) with
the ability to borrow under the Secured Credit Facility at a forward looking term rate based on the secured overnight financing
rate (“Term SOFR”) plus the Secured Credit Facility Margin and a Term SOFR spread adjustment of 0.10 percent.  The Secured
Credit  Facility  is  subject  to  permitted  extensions  and  certain  early  maturity  triggers,  including  if  on  any  date  the  aggregate
amount of scheduled principal repayments of indebtedness, with certain exceptions, due within 91 days thereof is equal to or in
excess  of  $200  million  and  available  cash  is  less  than  $250  million.   The  amended  secured  credit  facility  also  permits  us  to
increase  the  aggregate  amount  of  commitments  by  up  to  $250  million.    The  Secured  Credit  Facility  is  guaranteed  by
Transocean Ltd. and certain wholly owned subsidiaries.  The Secured Credit Facility is secured by, among other things, a lien
on  the  ultra-deepwater  floaters  Deepwater  Asgard,  Deepwater  Corcovado,  Deepwater  Invictus,  Deepwater  Mykonos,
Deepwater Orion, Deepwater Skyros, Development Driller III, Dhirubhai Deepwater KG2 and Discoverer Inspiration and the
harsh environment floaters Transocean Barents and Transocean Spitsbergen, and at December 31, 2022, the aggregate carrying
amount of which was $4.87 billion.

The Secured Credit Facility contains covenants that, among other things, include maintenance of a minimum guarantee
coverage  ratio  of  3.0  to  1.0,  a  minimum  collateral  coverage  ratio  of  2.1  to  1.0,  a  maximum  debt  to  capitalization  ratio  of
0.60 to 1.00 and minimum liquidity of $500 million.  The Secured Credit Facility also restricts the ability of Transocean Ltd.
and certain of our subsidiaries to, among other things, merge, consolidate or otherwise make changes to the corporate structure,
incur liens, incur additional indebtedness, enter into transactions with affiliates and pay dividends and other distributions.  In
order to utilize the Secured Credit Facility, we must, at the time of the borrowing request, be in full compliance with the terms
and  conditions  of  the  Secured  Credit  Facility  and  make  certain  representations  and  warranties,  including  with  respect  to
compliance with laws and solvency, to the lenders.  Repayment of borrowings under the Secured Credit Facility are subject to
acceleration upon the occurrence of an event of default.  Under the agreements governing certain of our debt and finance lease,
we  are  also  subject  to  various  covenants,  including  restrictions  on  creating  liens,  engaging  in  sale/leaseback  transactions  and
engaging  in  certain  merger,  consolidation  or  reorganization  transactions.    A  default  under  our  public  debt  indentures,  the
agreements governing our senior secured notes, our finance lease contract or any other debt owed to unaffiliated entities that
exceeds $125 million could trigger a default under the Secured Credit Facility and, if not waived by the lenders, could cause us
to lose access to the Secured Credit Facility.  At December 31, 2022, based on the credit rating of the Secured Credit Facility on
that date, the Secured Credit Facility Margin was 3.25 percent and the facility fee was 0.75 percent.  At December 31, 2022, we
had no borrowings outstanding, $6 million of letters of credit issued, and we had $767 million of available borrowing capacity
under the Secured Credit Facility.

Shipyard financing arrangement—At December 31, 2022, we have credit agreements that established the Shipyard
Loans  to  finance  all  or  a  portion  of  the  final  payments  owed  to  the  shipyard  upon  delivery  of  the  ultra-deepwater  floaters
Deepwater Atlas and Deepwater Titan.  Borrowings under the Shipyard Loan for Deepwater Atlas are secured by, among other
security, a lien on the rig, and borrowings under the Shipyard Loan for Deepwater Titan are unsecured.  We have the right to
prepay  outstanding  borrowings,  in  full  or  in  part,  without  penalty.   The  Shipyard  Loans  contain  covenants  that,  among  other
things, limit the ability of the subsidiary owners of the drilling rigs to incur certain types of additional indebtedness or make
certain  additional  commitments  or  investments.    In  June  2022,  we  borrowed  $349  million  under  the  Shipyard  Loan  for
Deepwater Atlas and made a cash payment of $46 million to satisfy the final milestone payment due upon delivery of the rig.  In
December  2022,  we  borrowed  $90  million  under  the  Shipyard  Loan  for  Deepwater  Titan  and  made  a  cash  payment  of
$325  million  to  satisfy  the  final  milestone  payment  due  upon  delivery  of  the  rig.    We  recorded  each  Shipyard  Loan,  net  of
imputed  interest,  with  an  initial  carrying  amount  of  $300  million  and  $82  million,  respectively,  and  corresponding  non-cash
capital additions, recorded in property and equipment.  The carrying amount of each Shipyard Loan at inception represented its
estimated fair value using significant other observable inputs, representative of Level 2 fair value measurements, including the
terms and credit spreads of our debt, by applying an estimated discount rate of 9.4 percent and 7.6 percent, respectively.

Bonds  may  be  exchanged  by  holders  into  Transocean  Ltd.  shares  at  any  time  prior  to  the  close  of  business  on  the
second  business  day  immediately  preceding  the  maturity  date  or  redemption  date.    The  4.625%  Senior  Guaranteed
Exchangeable  Bonds  may  be  exchanged  by  holders  at  any  time  prior  to  the  close  of  business  on  the  second  business  day
immediately preceding the maturity date or redemption date and, at our election, such exchange may be settled by delivering
cash, Transocean Ltd. shares or a combination of cash and shares.

Effective interest rates and fair values—At December 31, 2022, the effective interest rates and estimated fair values

of our exchangeable bonds were as follows (in millions, except effective interest rates):

0.50% Exchangeable Senior Bonds due January 2023
4.00% Senior Guaranteed Exchangeable Bonds due December 2025
2.50% Senior Guaranteed Exchangeable Bonds due January 2027

The  4.625%  Senior  Guaranteed  Exchangeable  Bonds  contain  a  compound  exchange  feature  that,  in  addition  to  the
exchange terms outlined above, requires us to pay holders a make whole premium of future interest through March 30, 2028, for
exchanges  exercised  during  a  redemption  notice  period.    Such  compound  exchange  feature  must  be  bifurcated  from  the  host
debt instrument since it is not considered indexed to our stock.  Accordingly, we recognize changes to the estimated fair value of
the  bifurcated  compound  exchange  feature,  recorded  as  a  component  of  the  carrying  amount  of  debt,  with  a  corresponding
adjustment to interest expense.  In the year ended December 31, 2022, we recognized an unrealized loss of $157 million as an
adjustment to the fair value of the bifurcated compound exchange feature.

We estimated the fair values of the exchangeable debt instruments, including the exchange features, by employing a
binomial lattice model using significant other observable inputs, representative of Level 2 fair value measurements, including
the terms and credit spreads of our debt and the expected volatility of the market price for our shares.

Related  balances—At  December  31,  2022  and  2021,  the  premium  associated  with  the  original  issuance  of  the
0.50%  Exchangeable  Senior  Bonds  had  a  carrying  amount  of  $172  million,  recorded  in  equity  as  a  component  of  additional
paid-in capital.

Debt issuance

Senior  guaranteed  exchangeable  bonds—On  September  30,  2022,  we  issued  $300  million  aggregate  principal
amount of 4.625% Senior Guaranteed Exchangeable Bonds in connection with exchange and purchase agreements.  Pursuant to
the  exchange  and  purchase  agreements,  we  exchanged  (the  “2022  Private  Exchange”)  (a)  $73  million  aggregate  principal
amount of the 0.50% Exchangeable Senior Bonds for (i) $73 million aggregate principal amount of 4.625% Senior Guaranteed
Exchangeable Bonds and (ii) 6.7 million warrants to purchase Transocean Ltd. shares, and (b) $43 million aggregate principal
amount  of  the  7.25%  senior  notes  due  November  2025  for  $39  million  aggregate  principal  amount  of  the  4.625%  Senior
Guaranteed  Exchangeable  Bonds.    In  the  year  ended  December  31,  2022,  as  a  result  of  the  2022  Private  Exchange,  we
recognized  a  gain  of  $6  million  ($0.01  per  diluted  share),  with  no  tax  effect,  associated  with  the  retirement  of  debt.
 Additionally,  we  sold  $188  million  aggregate  principal  amount  of  the  4.625%  Senior  Guaranteed  Exchangeable  Bonds  and
issued 15.5 million warrants to purchase Transocean Ltd. shares for aggregate net cash proceeds of $188 million.  On or after
March  30,  2026,  we  may  redeem  for  cash  all  or  a  portion  of  the  4.625%  Senior  Guaranteed  Exchangeable  Bonds  at  a  price
equivalent to the aggregate principal amount to be redeemed if the closing price of our shares has been greater than 115 percent
of the exchange price for a period of at least 20 trading days.  The initial carrying amount of the 4.625% Senior Guaranteed
Exchangeable  Bonds,  measured  at  the  estimated  fair  value  on  the  date  of  issuance,  was  $281  million.   We  estimated  the  fair
value of the exchangeable debt instrument, including the exchange feature, by employing a binomial lattice model and by using
significant other observable inputs, representative of Level 2 fair value measurements, including the terms and credit spreads of
our debt and expected volatility of the market price for our shares.  See Note 13—Equity.

On  February  26,  2021,  we  issued  $294  million  aggregate  principal  amount  of  the  4.00%  Senior  Guaranteed
Exchangeable Bonds and made an aggregate cash payment of $11 million in private exchanges (the “2021 Private Exchange”)
for $323 million aggregate principal amount of the 0.50% Exchangeable Senior Bonds.  In the year ended December 31, 2021,
as  a  result  of  the  2021  Private  Exchange,  we  recognized  a  gain  of  $51  million  ($0.08  per  diluted  share),  with  no  tax  effect,
associated  with  the  retirement  of  debt.    The  initial  carrying  amount  of  the  4.00%  Senior  Guaranteed  Exchangeable  Bonds,
measured at the estimated fair value on the date of issuance, was $260 million.  We estimated the fair value of the exchangeable
debt  instrument,  including  the  exchange  feature,  by  employing  a  binomial  lattice  model  using  significant  other  observable
inputs,  representative  of  Level  2  fair  value  measurements,  including  the  terms  and  credit  spreads  of  our  debt  and  expected
volatility of the market price for our shares.

On August 14, 2020, we issued $238 million aggregate principal amount of 2.50% Senior Guaranteed Exchangeable
Bonds  in  non-cash  private  exchanges  (the  “2020  Private  Exchange”)  for  $397  million  aggregate  principal  amount  of  the
0.50%  Exchangeable  Senior  Bonds.    In  the  year  ended  December  31,  2020,  as  a  result  of  the  2020  Private  Exchange,  we
recognized a gain of $72 million ($0.12 per diluted share), with no tax effect, associated with the restructuring of debt.  We may
redeem all or a portion of the 2.50% Senior Guaranteed Exchangeable Bonds (i) before August 14, 2023, if certain conditions

conversion feature of the 2.50% Senior Guaranteed Exchangeable Bonds, measured at its estimated fair value of $46 million, to
additional paid-in capital.  We estimated the fair value by employing a binomial lattice model using significant other observable
inputs, representative of Level 2 fair value measurements, including the expected volatility of the market price for our shares.

Related party transactions—In  August  2020,  Perestroika  exchanged  $356  million  aggregate  principal  amount  of  the
0.50%  Exchangeable  Senior  Bonds  for  $213  million  aggregate  principal  amount  of  2.50%  Senior  Guaranteed  Exchangeable
Bonds.    Perestroika  has  certain  registration  rights  related  to  its  shares  and  shares  that  may  be  issued  in  connection  with  any
exchange of its 2.50% Senior Guaranteed Exchangeable Bonds.  At December 31, 2022 and 2021, Perestroika held $213 million
aggregate principal amount of the 2.50% Senior Guaranteed Exchangeable Bonds.

Priority guaranteed senior unsecured notes—On September 11, 2020, we issued $687 million aggregate principal
amount of 11.50% senior guaranteed notes due January 2027 (the “11.50% Senior Guaranteed Notes”) in non-cash exchange
offers, pursuant to an exchange offer memorandum, dated August 10, 2020, as supplemented, for an aggregate principal amount
of  $1.5  billion  of  several  series  of  our  existing  debt  securities  that  were  validly  tendered  and  accepted  for  purchase  (the
“2020 Exchange Offers” and, together with the 2020 Private Exchange, the “2020 Exchange Transactions”).  In the year ended
December 31, 2020, as a result of the 2020 Exchange Offers, we recognized a gain of $355 million ($0.58 per diluted share),
with  no  tax  effect,  associated  with  the  restructuring  of  debt  (see  “—Debt  repayment,  redemption,  restructuring,  and
retirement”).  We may redeem all or a portion of the 11.50% Senior Guaranteed Notes prior to July 30, 2023 at a price equal to
100 percent of the aggregate principal amount plus a make-whole premium, and subsequently, at specified redemption prices.
 We may also use the net cash proceeds of certain equity offerings by Transocean Ltd. to redeem, on one or more occasions
prior  to  July  30,  2023,  up  to  a  maximum  of  40  percent  of  the  original  aggregate  principal  amount  of  the  11.50%  Senior
Guaranteed  Notes,  subject  to  certain  adjustments,  at  a  redemption  price  equal  to  111.50  percent  of  the  aggregate  principal
amount.

Guaranteed senior unsecured notes—On January 17, 2020, we issued $750 million aggregate principal amount of
8.00% senior notes due February 2027 (the “8.00% Senior Notes”), and we received aggregate cash proceeds of $743 million,
net of issue costs.  We may redeem all or a portion of the 8.00% Senior Notes on or prior to February 1, 2023 at a price equal to
100 percent of the aggregate principal amount plus a make-whole premium, and subsequently, at specified redemption prices.

Debt repayment, redemption, restructuring, and retirement

Restructuring and early retirement—During the years ended December 31, 2022, 2021 and 2020, we restructured or
retired certain notes as a result of exchange offers, private exchanges, redemption, tender offers and open market repurchases.
 We recorded the 2020 Exchange Transactions completed in August 2020 and September 2020 under ASC 470-60, Troubled
Debt  Restructuring  by  Debtors.    The  aggregate  principal  amounts,  cash  payments  and  recognized  gain  or  loss  for  such
transactions were as follows (in millions):

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

of the outstanding 6.50% senior notes due November 2020.  In the years ended December 31, 2022, 2021 and 2020, we made an
aggregate cash payment of $479 million, $478 million and $375 million, respectively, to repay other indebtedness in scheduled
installments.

Subsequent events

Debt issuance—In January 2023, we issued $525 million aggregate principal amount of 8.375% senior secured notes
due February 2028 (the “8.375% Senior Secured Notes”), and we received $515 million aggregate cash proceeds, net of issue
costs.    The  8.375%  Senior  Secured  Notes  are  secured  by  the  assets  and  earnings  associated  with  the  ultra-deepwater  floater
Deepwater Titan and the equity of the wholly owned subsidiary that owns or operates the collateral rig.  Additionally, we are
required to maintain certain balances in a restricted cash account to satisfy debt service requirements.  We may redeem all or a
portion of the 8.375% Senior Secured Notes on or prior to February 1, 2025 at a price equal to 100 percent of the aggregate
principal amount plus a make-whole premium, and subsequently, at specified redemption prices.

In  January  2023,  we  issued  $1.175  billion  aggregate  principal  amount  of  8.75%  senior  secured  notes  due
February 2030 (the “8.75% Senior Secured Notes”), and we received $1.157 billion aggregate cash proceeds, net of issue costs.
 The 8.75% Senior Secured Notes are fully and unconditionally guaranteed on an unsecured basis by Transocean Ltd. and on a
limited senior secured basis by certain of our wholly owned subsidiaries.  The 8.75% Senior Secured Notes are secured by a lien
on  the  ultra-deepwater  floaters  Deepwater  Pontus,  Deepwater  Proteus  and  Deepwater  Thalassa  and  the  harsh  environment
floaters Transocean Enabler and Transocean Encourage, together with certain related assets.  Additionally, we are required to
maintain certain balances in a restricted cash account to satisfy debt service requirements.

Debt retirement—On  the  scheduled  maturity  date  of  January  30,  2023,  we  made  a  cash  payment  of  $49  million  to

repay an equivalent aggregate principal amount of the outstanding 0.50% Exchangeable Senior Bonds.

In January 2023, we made a cash payment of $121 million to redeem an equivalent aggregate principal amount of the
outstanding 5.375% Senior Secured Notes, and the trustee notified holders of our intent to redeem the remaining outstanding
$122  million  aggregate  principal  amount  of  notes  for  an  equivalent  aggregate  cash  payment,  expected  to  be  made  on
February 24, 2023.

In January 2023, in connection with the issuance of the 8.75% Senior Secured Notes, we made an aggregate payment
of  $1.156  billion,  including  a  make-whole  premium,  to  redeem  the  remaining  outstanding  $311  million,  $240  million,
$250  million,  and  $336  million  aggregate  principal  amount  of  the  5.875%  Senior  Secured  Notes,  the  7.75%  Senior  Secured
Notes, the 6.25% Senior Secured Notes and the 6.125% Senior Secured Notes, respectively.

NOTE 9—POSTEMPLOYMENT BENEFIT PLANS

Defined contribution plans

We sponsor defined contribution plans for our employees in most markets in which we operate worldwide, the most
significant  of  which  were  as  follows:  (1)  a  qualified  savings  plan  covering  certain  eligible  employees  working  in  the  U.S.,
(2)  various  savings  plans  covering  eligible  employees  working  in  Norway,  (3)  a  non-qualified  savings  plan  covering  certain
eligible  employees  working  outside  the  U.S.,  the  United  Kingdom  (“U.K.”)  and  Norway  and  (4)  a  qualified  savings  plan
covering certain eligible employees working in the U.K.  In the years ended December 31, 2022, 2021 and 2020, we recognized
expense  of  $61  million,  $52  million  and  $56  million,  respectively,  related  to  our  defined  contribution  plans,  recorded  in  the
same financial statement line item as cash compensation paid to the respective employees.

Defined benefit pension and other postemployment benefit plans

Overview—As  of  December  31,  2022,  we  had  defined  benefit  plans  in  the  U.S.,  including  three  funded  and
three  unfunded  defined  benefit  plans  (the  “U.S.  Plans”),  and  in  the  U.K.,  we  had  one  funded  defined  benefit  plan  (the
“U.K. Plan”).  During the year ended December 31, 2021, as required by local authorities, we terminated our remaining plans in
Norway (together with the U.K. Plan, the “Non-U.S. Plans”).  We also maintain certain unfunded other postemployment benefit
plans (collectively, the “OPEB Plans”), under which benefits to eligible participants diminish during a phase-out period ending
December 31, 2025.  We maintain the benefit obligations under our plans until they are fully satisfied.

Net  periodic  benefit  costs—We  estimated  our  net  periodic  benefit  costs  using  the  following  weighted-average

assumptions:

We  periodically  review  our  investment  policies,  plan  assets  and  asset  allocation  strategies  to  evaluate  performance
relative  to  specified  objectives.    In  determining  our  asset  allocation  strategies  for  the  U.S.  Plans,  we  review  the  results  of
regression  models  to  assess  the  most  appropriate  target  allocation  for  each  plan,  given  the  plan’s  status,  demographics  and
duration.  For the U.K. Plan, the plan trustees establish the asset allocation strategies consistent with the regulations of the U.K.
pension  regulators  and  in  consultation  with  financial  advisors  and  company  representatives.    Investment  managers  for  the
U.S. Plans and the U.K. Plan are given established ranges within which the investments may deviate from the target allocations.

We  estimated  the  fair  values  of  the  plan  assets  by  applying  the  market  approach,  as  categorized  above,  using  either
(i) significant observable inputs, representative of Level 1 fair value measurements, including market prices of actively traded
funds, or (ii) significant other observable inputs, representative of Level 2 fair value measurements, including market prices of
the  underlying  securities  in  the  collective  trust  funds.    The  U.S.  Plans  and  the  U.K.  Plan  invest  in  passively  and  actively
managed funds that are referenced to or benchmarked against market indices.  The plan investment managers have discretion to
select the securities held within each asset category.  Given this discretion, the managers may occasionally invest in our debt or
equity securities and may hold either long or short positions in such securities.  Since plan investment managers are required to
maintain well diversified portfolios, the actual investment in our securities would be immaterial relative to asset categories and
the overall plan assets.

Funding contributions and benefit payments—In the years ended December 31, 2022, 2021 and 2020, we made an
aggregate  contribution  of  $3  million,  $10  million  and  $14  million,  respectively,  to  the  defined  benefit  pension  plans  and  the
OPEB Plans using our cash

Overview—Transocean  Ltd.,  a  holding  company  and  Swiss  resident,  is  subject  to  Swiss  federal,  cantonal  and
communal income tax.  For Swiss income taxes, however, qualifying net dividend income and net capital gains on the sale of
qualifying investments in subsidiaries are exempt from taxation.  Consequently, there is not a direct relationship between our
Swiss earnings before income taxes and our Swiss income tax expense.

Tax  provision  and  rate—In  the  years  ended  December  31,  2022,  2021  and  2020,  our  effective  tax  rate  was
(10.4)  percent,  (25.7)  percent  and  (5.1)  percent,  respectively,  based  on  loss  before  income  tax  expense.    The  relationship
between our provision for or benefit from income taxes and our income or loss before income taxes can vary significantly from
period to period considering, among other factors, (a) the overall level of income before income taxes, (b) changes in the blend
of income that is taxed based on gross revenues rather than income before taxes, (c) rig movements between taxing jurisdictions
and (d) our rig operating structures.

The components of our income tax provision (benefit) were as follows (in millions):

Current tax expense (benefit)

In  January  2020,  Switzerland  made  effective  the  Federal  Act  on  Tax  Reform  and  AHV  Financing  (“TRAF”).    In
March 2020, we entered into discussions with the Swiss tax authorities regarding the manner by which the TRAF applies to
certain Swiss subsidiaries, which allows us to access historic depreciation and costs related to financing assets not previously
deducted on Swiss tax returns, which can be apportioned to offset taxable income based on the remaining useful lives of the rigs
and financing assets.  In the three months ended December 31, 2021, we reached an agreement with the Swiss Tax authorities
regarding  the  TRAF  treatment.    At  December  31,  2022  and  2021,  we  had  a  deferred  tax  liability  of  $226  million  and
$238  million,  respectively,  and  a  deferred  tax  asset  of  $1.23  billion  and  $1.33  billion,  respectively,  offset  with  a  valuation
allowance of $1.10 billion and $1.17 billion, respectively.

The Coronavirus Aid, Relief, and Economic Security Act, enacted in March 2020, made certain changes to U.S. tax
law,  including,  among  others,  extending  up  to  five  years  the  carryback  period  for  net  operating  losses  generated  between
December  31,  2017  and  January  1,  2021.    In  the  year  ended  December  31,  2020,  we  recognized  an  income  tax  benefit  of
$28 million related to the carryback of our net operating losses under this provision.

As  of  December  31,  2022,  we  include  taxes  related  to  the  earnings  of  all  of  our  subsidiaries  since  we  no  longer

consider the earnings of any of our subsidiaries to be indefinitely reinvested.

At  December  31,  2022  and  2021,  our  deferred  tax  assets  included  U.S.  foreign  tax  credits  of  $11  million  and
$19  million,  respectively,  which  will  expire  between  2024  and  2026.    Deferred  tax  assets  related  to  our  net  operating  losses
were  generated  in  various  worldwide  tax  jurisdictions.   At  December  31,  2022,  our  net  deferred  tax  assets  related  to  our  net
operating loss carryforwards included $682 million, which do not expire, and $433 million, which will expire between 2023 and
2038.

As  of  December  31,  2022,  our  consolidated  cumulative  loss  incurred  over  the  recent  three-year  period  represented
significant objective negative evidence for the evaluation of the realizability of our deferred tax assets.  Because such evidence
has limited our ability to consider other subjective evidence, we evaluate each jurisdiction separately.  We consider objective
evidence, such as contract backlog activity, in jurisdictions in which we have profitable contracts, and the ability to carryback
losses or utilize losses against potential exposures.  If estimated future taxable income changes during the carryforward periods
or if the cumulative loss is no longer present, we may adjust the amount of deferred tax assets that we expect to realize.  At
December 31, 2022 and 2021, due to uncertainty of realization, we had a valuation allowance of $1.91 billion and $1.82 billion,
respectively, on net operating losses and other deferred tax assets due to the uncertainty of realization.

Unrecognized  tax  benefits—The  changes  to  unrecognized  tax  benefits,  excluding  interest  and  penalties  that  we

recognize as a component of income tax expense, were as follows (in millions):

Balance, beginning of period
Additions for current year tax positions
Additions for prior year tax positions
Reductions related to statute of limitation expirations and changes in law
Reductions due to settlements
Reductions for prior year tax positions

Balance, end of period

In the years ended December 31, 2022, 2021 and 2020, we recognized, as a component of our income tax provision,
expense of $6 million, expense of $8 million and benefit of $7 million, respectively, related to interest and penalties associated
with  our  unrecognized  tax  benefits.    As  of  December  31,  2022,  we  have  unrecognized  benefits  of  $471  million,  including
interest and penalties, against which we have recorded net operating loss deferred tax assets of $383 million, resulting in net
unrecognized  tax  benefits  of  $88  million,  including  interest  and  penalties,  that  upon  reversal  would  favorably  impact  our
effective  tax  rate.    During  the  year  ending  December  31,  2023,  it  is  reasonably  possible  that  our  existing  liabilities  for
unrecognized  tax  benefits  may  increase  or  decrease,  primarily  due  to  the  progression  of  open  audits  and  the  expiration  of
statutes  of  limitation.    However,  we  cannot  reasonably  estimate  a  range  of  potential  changes  in  our  existing  liabilities  for
unrecognized tax benefits due to various uncertainties, such as the unresolved nature of various audits.

Tax  positions  and  returns—We  conduct  operations  through  our  various  subsidiaries  in  countries  throughout  the
world.    Each  country  has  its  own  tax  regimes  with  varying  nominal  rates,  deductions  and  tax  attributes  that  are  subject  to
changes  resulting  from  new  legislation,  interpretation  or  guidance.    From  time  to  time,  as  a  result  of  these  changes,  we  may
revise previously evaluated tax positions, which could cause us to adjust our recorded tax assets and liabilities.  Tax authorities
in certain jurisdictions are examining our tax returns and, in some cases, have issued assessments.  We intend to defend our tax
positions vigorously.  Although we can provide no assurance as to the outcome of the aforementioned changes, examinations or
assessments, we do not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial
position or results of operations; however, it could have a material adverse effect on our consolidated statement of cash flows.

Brazil tax investigations—In December 2005, the Brazilian tax authorities began issuing tax assessments with respect
to  our  tax  returns  for  the  years  2000  through  2004.    In  May  2014,  the  Brazilian  tax  authorities  issued  an  additional  tax
assessment  for  the  years  2009  and  2010.    We  filed  protests  with  the  Brazilian  tax  authorities  for  the  assessments  and  are
engaged in the appeals process, and a portion of two cases were favorably closed.  As of December 31, 2022, the remaining
aggregate  tax  assessment,  including  interest  and  penalties,  was  for  corporate  income  tax  of  BRL  668  million,  equivalent  to
approximately  $126  million,  and  indirect  tax  of  BRL  72  million,  equivalent  to  $14  million.    We  believe  our  returns  are
materially  correct  as  filed,  and  we  are  vigorously  contesting  these  assessments.   An  unfavorable  outcome  on  these  proposed
assessments  could  have  a  material  adverse  effect  on  our  consolidated  statement  of  financial  position,  results  of  operations  or
cash flows.

issued  under  various  committed  and  uncommitted  credit  lines  provided  by  banks  to  guarantee  various  contract  bidding,
performance activities and customs obligations.  At December 31, 2022 and 2021, we also had outstanding surety bonds totaling
$161  million  and  $146  million,  respectively,  to  secure  customs  obligations  related  to  the  importation  of  our  rigs  and  certain
performance and other obligations.  At December 31, 2022 and 2021, the aggregate cash collateral held by institutions to secure
our letters of credit and surety bonds was $7 million and $8 million, respectively.

Legal proceedings

Asbestos  litigation—In  2004,  several  of  our  subsidiaries  were  named,  along  with  numerous  other  unaffiliated
defendants, in complaints filed in the Circuit Courts of the State of Mississippi, and in 2014, a group of similar complaints were
filed  in  Louisiana.   The  plaintiffs,  former  employees  of  some  of  the  defendants,  generally  allege  that  the  defendants  used  or
manufactured  asbestos  containing  drilling  mud  additives  for  use  in  connection  with  drilling  operations,  claiming  negligence,
products liability, strict liability and claims allowed under the Jones Act and general maritime law.  The plaintiffs generally seek
awards of unspecified compensatory and punitive damages, but the court appointed special master has ruled that a Jones Act
employer  defendant,  such  as  us,  cannot  be  sued  for  punitive  damages.    One  of  our  subsidiaries  was  named  in  additional
complaints  filed  in  Illinois  and  Missouri,  where  the  plaintiffs  similarly  allege  that  the  defendants  manufactured  asbestos
containing products or used asbestos-containing drilling mud additives in connection with land-based drilling operations.  At
December 31, 2022, seven plaintiffs have claims pending in Louisiana and 12 plaintiffs in the aggregate have claims pending in
either Illinois or Missouri, in which we have or may have an interest.  We intend to defend these lawsuits vigorously, although
we  can  provide  no  assurance  as  to  the  outcome.   We  historically  have  maintained  broad  liability  insurance,  although  we  can
provide  no  assurance  as  to  whether  insurance  will  cover  the  liabilities,  if  any,  arising  out  of  these  claims.    Based  on  our
evaluation of the exposure to date, we do not expect the liability, if any, resulting from these claims to have a material adverse
effect on our consolidated statement of financial position, results of operations or cash flows.

One of our subsidiaries was named as a defendant, along with numerous other companies, in lawsuits arising out of the
subsidiary’s manufacture and sale of heat exchangers, and involvement in the construction and refurbishment of major industrial
complexes  alleging  bodily  injury  or  personal  injury  as  a  result  of  exposure  to  asbestos.    As  of  December  31,  2022,  the
subsidiary  was  a  defendant  in  approximately  238  lawsuits  with  a  corresponding  number  of  plaintiffs.    For  many  of  these
lawsuits, we have not been provided sufficient information from the plaintiffs to determine whether all or some of the plaintiffs
have claims against the subsidiary, the basis of any such claims, or the nature of their alleged injuries.  The operating assets of
the subsidiary were sold in 1989.  In December 2021, the subsidiary and certain insurers agreed to a settlement of outstanding
disputes that provide the subsidiary with cash.  An earlier settlement, achieved in September 2018, provided the subsidiary with
cash and an annuity that begins making payments in 2024.  Together with a coverage-in-place agreement with certain insurers
and  additional  coverage  issued  by  other  insurers,  we  believe  the  subsidiary  has  sufficient  resources  to  respond  to  both  the
current lawsuits as well as future lawsuits of a similar nature.  While we cannot predict or provide assurance as to the outcome
of these matters, we do not expect the ultimate liability, if any, resulting from these claims to have a material adverse effect on
our consolidated statement of financial position, results of operations or cash flows.

Other matters—We  are  involved  in  various  regulatory  matters  and  a  number  of  claims  and  lawsuits,  asserted  and
unasserted, all of which have arisen in the ordinary course of our business.  We do not expect the liability, if any, resulting from
these other matters to have a material adverse effect on our consolidated statement of financial position, results of operations or
cash flows.  We cannot predict with certainty the outcome or effect of any of the litigation matters specifically described above
or  of  any  such  other  pending,  threatened,  or  possible  litigation  or  liability.   We  can  provide  no  assurance  that  our  beliefs  or
expectations  as  to  the  outcome  or  effect  of  any  tax,  regulatory,  lawsuit  or  other  litigation  matter  will  prove  correct  and  the
eventual outcome of these matters could materially differ from management’s current estimates.

Environmental matters

We have certain potential liabilities under the Comprehensive Environmental Response, Compensation, and Liability
Act (“CERCLA”) and similar state acts regulating cleanup of hazardous substances at various waste disposal sites, including
those  described  below.    CERCLA  is  intended  to  expedite  the  remediation  of  hazardous  substances  without  regard  to  fault.
 Potentially responsible parties (“PRPs”) for each site include present and former owners and operators of, transporters to and
generators of the substances at the site.  It is difficult to quantify the potential cost of environmental matters and remediation
obligations.  Liability is strict and can be joint and several.

One of our subsidiaries was named as a PRP in connection with a site located in Santa Fe Springs, California, known
as  the  Waste  Disposal,  Inc.  site.    We  and  other  PRPs  agreed,  under  a  participation  agreement  with  the  U.S.  Environmental
Protection Agency (the “EPA”) and the U.S. Department of Justice, to settle our potential liabilities by remediating the site.  The
remedial  action  for  the  site  was  completed  in  2006.    Our  share  of  the  ongoing  operating  and  maintenance  costs  has  been
insignificant, and we do not expect any additional potential liabilities to be material.  Resolutions of other claims by the EPA,
the  involved  state  agency  or  PRPs  are  at  various  stages  of  investigation.    Nevertheless,  based  on  available  information  with
respect to all environmental matters, including all related pending legal proceedings, asserted legal claims and known potential
legal claims that are likely to be asserted, we do not expect the ultimate liability, if any, resulting from such matters, to have a
material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

NOTE 13—EQUITY

Share issuance—We maintain an at-the-market equity offering program (the “ATM Program”).  We intend to use the
net  proceeds  from  our  ongoing  ATM  Program  for  general  corporate  purposes,  which  may  include,  among  other  things,  the
repayment or refinancing of indebtedness and the funding of working capital, capital expenditures, investments and additional
balance sheet liquidity.  In June 2021, we entered into an equity distribution agreement with a sales agent for the offer and sale
of our shares, with a maximum aggregate net offering price of up to $400 million, under the ATM Program.  In August 2022,
we  entered  into  an  equity  distribution  agreement  with  a  sales  agent  for  the  offer  and  sale  of  our  shares,  with  a  maximum
aggregate net offering price of up to $435 million, under the ATM Program.  In the years ended December 31, 2022 and 2021,
we received aggregate cash proceeds of $263 million and $158 million, respectively, net of issue costs, for the aggregate sale of
61.0 million shares and 36.1 million shares, respectively, under the ATM Program.

Warrants—On  September  30,  2022,  in  connection  with  the  issuance  and  sale  of  the  4.625%  Senior  Guaranteed
Exchangeable Bonds in the 2022 Private Exchange, we issued 22.2 million warrants to purchase Transocean Ltd. shares.  The
warrants may be exercised by holders at any time prior to the close of business on March 13, 2026 at an exercise price equal to
$3.71 per share, subject to certain anti-dilutive adjustments, and at our election, such exercise may be settled by delivering cash,
Transocean  Ltd.  shares  or  a  combination  of  cash  and  shares.    If  at  any  time  prior  to  expiration,  the  closing  price  of
Transocean Ltd. shares equals or exceeds $10.00 per share, subject to adjustment upon the occurrence of certain events, for a
period of five consecutive trading days, we will have the right to effect an exercise of all, but not less than all, of the warrants
upon notice to holders.  The initial carrying amount of the warrants, recorded in additional paid-in capital and measured at the
estimated fair value on the date of issuance, was $16 million, net of issue costs.  We estimated the fair value of the warrants by
employing  a  binomial  lattice  model  and  by  using  significant  other  observable  inputs,  representative  of  Level  2  fair  value
measurements, including the expected volatility of the market price for our shares.

Shares held by subsidiaries—One of our subsidiaries holds our shares for future use to deliver shares in connection
with sales under the ATM Program and in connection with awards granted under our incentive plans or other rights to acquire
our shares.  At December 31, 2022 and 2021, our subsidiary held 75.4 million and 72.7 million shares, respectively.

NOTE 14—SHARE-BASED COMPENSATION

Overview

We  have  a  long-term  incentive  plan  (the  “Long-Term  Incentive  Plan”)  for  executives,  key  employees  and  non-
employee  directors  under  which  awards  can  be  granted  in  the  form  of  restricted  share  units,  restricted  shares,  stock  options,
stock appreciation rights and cash performance awards.  Awards may be granted as service awards that are earned over a defined
service  period  or  as  performance  awards  that  are  earned  based  on  the  achievement  of  certain  market  factors  or  performance
targets  or  a  combination  of  market  factors  and  performance  targets.    The  compensation  committee  of  our  board  of  directors
determines the terms and conditions of the awards granted under the Long-Term Incentive Plan.  At December 31, 2022, we had
85.7  million  shares  authorized  and  13.6  million  shares  available  to  be  granted  under  the  Long-Term  Incentive  Plan.    At
December  31,  2022,  the  total  unrecognized  compensation  cost  related  to  our  unvested  share-based  awards  was  $38  million,
which we expect to recognize over a weighted-average period of 1.7 years.

Service awards typically vest either in three  equal  annual  installments  beginning  on  the  first  anniversary  date  of  the
grant or in an aggregate installment at the end of the stated vesting period.  Service-based stock options, once fully vested, are
typically exercisable during a seven-year period.  Performance awards typically vest in one aggregate installment following the
ultimate  determination  date.    Performance  awards  are  typically  subject  to  a  three-year  measurement  period  during  which  the
number of shares to be issued remains uncertain until the end of the performance period, at which time the awarded number of
shares to be issued is determined.

Cash  and  cash  equivalents—Our  cash  and  cash  equivalents  are  primarily  invested  in  demand  deposits,  short-term
time deposits and money market funds.  The carrying amount of our cash and cash equivalents represents the historical cost,
plus accrued interest, which approximates fair value because of the short maturities of the instruments.

Restricted cash and cash equivalents—Our restricted cash and cash equivalents, which are subject to restrictions due
to collateral requirements, legislation, regulation or court order, are primarily invested in demand deposits and money market
funds.    The  carrying  amount  of  our  restricted  cash  and  cash  equivalents  represents  the  historical  cost,  plus  accrued  interest,
which approximates fair value because of the short maturities of the instruments.

Long-term loans receivable from unconsolidated affiliates—The carrying amount of our long-term loans receivable
from unconsolidated affiliates, recorded in other assets, represents the principal amount of the cash investment.  We estimated
the  fair  value  of  our  long-term  loans  receivable  from  unconsolidated  affiliates  using  significant  unobservable  inputs,
representative of Level 3 fair value measurements, including the terms and credit spreads for the instruments.

Total debt—The carrying amount of our total debt represents the principal amount, contractual interest payments of
previously restructured debt and unamortized discounts, premiums and issue costs.  The carrying amount and fair value of our
total debt includes amounts related to certain exchangeable debt instruments (see Note 8—Debt).  We estimated the fair value of
our total debt using significant other observable inputs, representative of Level 2 fair value measurements, including the terms
and  credit  spreads  for  the  instruments  and,  with  respect  to  the  exchangeable  debt  instruments,  the  expected  volatility  of  the
market price for our shares.

NOTE 18—RISK CONCENTRATION

Interest rate risk—We are exposed to the interest rate risk related to our fixed-rate debt when we refinance maturing
debt with new debt or when we early retire debt in open market repurchases, exchanges or other market transactions.  We are
also  exposed  to  interest  rate  risk  related  to  our  restricted  and  unrestricted  cash  equivalents,  as  the  interest  income  earned  on
these investments is based on variable or short-term interest rates, which change with market interest rates.

Currency exchange rate risk—We are exposed to currency exchange rate risk primarily related to contract drilling
revenues,  employee  compensation  costs  and  purchasing  costs  that  are  denominated  in  currencies  other  than  our  functional
currency, the U.S. dollar.  We use a variety of techniques to minimize the exposure to currency exchange rate risk, including the
structuring of customer contract payment terms and occasional use of forward exchange contracts.  Our primary tool to manage
currency  exchange  rate  risk  involves  structuring  customer  contracts  to  provide  for  payment  in  both  U.S.  dollars  and  local
currency.    The  payment  portion  denominated  in  local  currency  is  based  on  anticipated  local  currency  requirements  over  the
contract term.  Due to various factors, including customer acceptance, local banking laws, national content requirements, other
statutory  requirements,  local  currency  convertibility,  local  inflation  and  revenue  efficiency,  actual  local  currency  needs  may
vary from those realized in the customer contracts, resulting in partial exposure to currency exchange rate risk.  The currency
exchange effect resulting from our international operations generally has not had a material impact on our operating results.

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

Credit risk—We are exposed to concentrations of credit risk primarily related to our restricted and unrestricted cash
and  cash  equivalents  and  customer  receivables,  both  current  and  long-term.    We  generally  maintain  our  restricted  and
unrestricted  cash  and  cash  equivalents  in  time  deposits  at  commercial  banks  with  high  credit  ratings  or  mutual  funds,  which
invest  exclusively  in  high-quality  money  market  instruments,  and  because  we  limit  the  amount  of  exposure  to  any
one institution, we do not believe we are exposed to any significant credit risk.  Our customer receivables, which are dispersed
in  various  countries,  are  due  from  integrated  energy  companies,  government-owned  or  government-controlled  energy
companies  and  other  independent  energy  companies.    For  such  receivables,  we  establish  an  allowance  for  credit  losses  by
applying an expected loss rate based on current and forecasted future and historical experience.  Although we have encountered
only isolated credit concerns related to independent energy companies, we occasionally require collateral or other security to
support customer receivables.  In certain infrequent instances, when we determine that collection is not reasonably assured, we
may offer extended payment terms and recognize revenues associated with the contract on a cash basis.

Labor agreements—At December 31, 2022, we had a global workforce of approximately 5,340 individuals, including
approximately 300 contractors.  Approximately 43 percent of our total workforce, working primarily in Norway, Brazil and the
U.K., are represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially all
of which are subject to annual salary negotiation.  Negotiations over annual salary or other labor matters could result in higher
personnel  or  other  costs  or  increased  operational  restrictions  or  disruptions.   The  outcome  of  any  such  negotiation  generally
affects the market for all offshore employees, not only union members.  A failure to reach an agreement on certain key issues
could result in strikes, lockouts or other work stoppages.

ITEM 9. CHANGES  IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND

FINANCIAL DISCLOSURE

We  have  not  had  a  change  in  or  disagreement  with  our  accountants  within  24  months  prior  to  the  date  of  our  most

recent financial statements or in any period subsequent to such date.

ITEM 9A.CONTROLS AND PROCEDURES

Disclosure  controls  and  procedures—Our  disclosure  controls  and  procedures  are  designed  to  provide  reasonable
assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is (1) accumulated
and communicated to our management, including our Chief Executive Officer, who is our principal executive officer, and our
Chief  Financial  Officer,  who  is  our  principal  financial  officer,  to  allow  timely  decisions  regarding  required  disclosure  and
(2)  recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  U.S.  Securities  and  Exchange
Commission’s rules and forms.  Under the supervision and with the participation of management, including our Chief Executive
Officer and Chief Financial Officer, we performed an evaluation of the effectiveness of our disclosure controls and procedures
as of the end of the period covered by this report.  Based on that evaluation, our Chief Executive Officer and Chief Financial
Officer concluded that our disclosure controls and procedures were effective as of December 31, 2022.

Internal control over financial reporting—There has been no change to our internal control over financial reporting
during the quarter ended December 31, 2022 that has materially affected or is reasonably likely to materially affect our internal
control  over  financial  reporting.    See  “Management’s  Report  on  Internal  Control  Over  Financial  Reporting”  and  “Report  of
Independent Registered Public Accounting Firm,” included in Item 8 of this annual report.

Other  matters—In  July  2022,  we  deployed  a  new  global  Enterprise  Resource  Planning  (“ERP”)  and  Enterprise
Performance Management (“EPM”) system, designed to optimize and standardize processes in treasury, accounting, financial
planning,  supply  chain  management,  asset  management  and  information  technology.   Although  we  are  updating  our  internal
controls that have been affected by the ERP and EPM deployment, we do not believe it has had an adverse effect on our internal
control over financial reporting.

DESCRIPTION OF TRANSOCEAN LTD.’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.1

As of December 31, 2022, Transocean Ltd. had two classes of securities registered under Section 12 of the Securities
Exchange Act of 1934, as amended: registered shares, par value CHF 0.10 per share (“shares”)  and  exchangeable
bonds due 2023 (“Exchangeable Bonds”).

Description of the Shares

The following description of Transocean Ltd.’s shares is a summary and is subject to the complete text of our Articles
of  Association,  filed  as  Exhibit  3.1  to  our  Current  Report  on  Form  8-K  (Commission  File  No.  001-38373)  filed  on
September 13, 2022. We encourage you to read the Articles of Association carefully. In this description, references to
“Transocean,” “we,” ”our,” and “us” mean Transocean Ltd.

Description of Share Capital

Issued Share Capital. As  of  February  14,  2023,  the  share  capital  of  Transocean  registered  shares  in  the  commercial
register, which reflects Transocean’s total issued share capital, excluding shares issued out of Transocean’s conditional
share  capital  not  yet  registered  with  the  commercial  register,  was  CHF  79,724,407.20,  divided  into  797,244,072
registered  Transocean  shares,  par  value  0.10  Swiss  francs  per  share.  The  total  issued  share  capital  of  Transocean,
including  Transocean  shares  issued  out  of  Transocean’s  conditional  share  capital  not  yet  registered  with  the
commercial  register,  was  79,724,533.50  Swiss  francs,  divided  into  797,245,335  registered  Transocean  shares,  par
value  0.10  Swiss  francs  per  share.  The  issued  Transocean  shares  are  fully  paid,  non-assessable,  and  rank  pari  passu
with each other and all other Transocean shares.

General Authorized Share Capital. Our board of directors is authorized to issue new shares at any time until May 12,
2024, and thereby increase the stated share capital by a maximum amount of 10,784,875.60 Swiss francs by issuing a
maximum of 107,848,756 shares. Our general authorized share capital expires on May 12, 2024.

Our  board  of  directors  determines  the  time  of  the  issuance,  the  issuance  price,  the  manner  in  which  the  new
Transocean shares have to be paid in, the date from which the new Transocean shares carry the right to dividends and,
subject to the provisions of our Articles of Association, the conditions for the exercise of the preemptive rights with
respect to the issuance and the allotment of preemptive rights that are not exercised. The board of directors may allow
preemptive  rights  that  are  not  exercised  to  expire,  or  it  may  place  such  rights  or  Transocean  shares,  the  preemptive
rights  in  respect  of  which  have  not  been  exercised,  at  market  conditions  or  use  them  otherwise  in  our  interest.  For
further information on preemptive rights with respect to our authorized share capital, see “—Preemptive Rights and
Advance Subscription Rights” below.

An  increase  of  the  share  capital  (i)  by  means  of  an  offering  underwritten  by  a  financial  institution,  a  syndicate  of
financial institutions or another third party or third parties, followed by an offer to the then-existing shareholders of
Transocean, and (ii) in partial amounts is permissible.

The  shares  will  be  subject  to  the  limitations  for  registration  in  the  share  register  pursuant  to  Articles  7  and  9  of
Transocean’s Articles of Association.

Conditional Share Capital. Article  6  of  Transocean’s  Articles  of  Association  has  not  yet  been  updated  to  reflect  the
issuance  of  1,263  shares  following  the  exercise  of  certain  of  our  Exchangeable  Bonds.  Accordingly,  the  remaining
authority to issue shares out of conditional share capital is limited to a maximum of 142,362,093 shares; these shares
may be issued through:

● the exercise of conversion, exchange, option, warrant or similar rights for the subscription of shares granted

to third parties or shareholders in connection with bonds, options, warrants or other securities newly or

1

already issued in national or international capital markets or new or already existing contractual obligations
by or of us or any of our group companies or any of our respective predecessors; or

● in  connection  with  the  issuance  of  shares,  options  or  other  share-based  awards  to  members  of  the  board  of
directors,  members  of  our  executive  management,  employees,  contractors,  consultants  or  other  persons
providing services to us or our subsidiaries.

For  information  on  preemptive  rights  with  respect  to  our  conditional  share  capital,  see  “—Preemptive  Rights  and
Advance Subscription Rights” below.

Other Classes or Series of Transocean Shares / Non-voting stock (Genussscheine / Partizipationsscheine). The board
of directors may not create Transocean shares with increased voting powers without the affirmative resolution adopted
by  shareholders  holding  at  least  two-thirds  of  the  voting  rights  and  an  absolute  majority  of  the  par  value  of  the
Transocean shares, each as represented (in person or by proxy) at a general meeting of the shareholders. Our board of
directors  may  create  preferred  stock  with  the  vote  of  a  majority  of  the  votes  cast  at  a  general  meeting  of  our
shareholders (not counting broker non-votes, abstentions and blank or invalid ballots).

Transocean has not issued any non-voting stock to date (Partizipationsscheine, Genussscheine).

Preemptive Rights and Advance Subscription Rights

Under the Swiss Code of Obligations (the “Swiss Code”), the prior approval of a general meeting of shareholders is
generally  required  to  authorize,  for  later  issuance,  the  issuance  of  Transocean  shares,  or  rights  to  subscribe  for,  or
convert into, Transocean shares (which rights may be connected to debt instruments or other obligations). In addition,
the existing shareholders will have preemptive rights in relation to such Transocean shares or rights in proportion to
the  respective  par  values  of  their  holdings.  The  shareholders  may,  with  the  affirmative  vote  of  shareholders  holding
two-thirds  of  the  voting  rights  and  a  majority  of  the  par  value  of  the  Transocean  shares  represented  at  the  general
meeting,  withdraw  or  limit  the  preemptive  rights  for  valid  reasons  (such  as  a  merger,  an  acquisition  or  any  of  the
reasons authorizing the board of directors to withdraw or limit the preemptive rights of shareholders in the context of
an authorized capital increase as described below).

If the general meeting of shareholders has approved the creation of authorized or conditional capital, it may delegate
the decision whether to withdraw or limit the preemptive and advance subscription rights for valid reasons to the board
of directors. However, the valid reasons justifying the exclusion of the preemptive right must be stated in the articles of
association.  Our  Articles  of  Association  provide  for  this  delegation  and  state  the  valid  reasons  with  respect  to  our
authorized  and  conditional  share  capital  in  the  circumstances  described  below  under  “—General  Authorized  Share
Capital” and “—Conditional Share Capital.”

General Authorized Share Capital. At any time until May 12, 2024, and pursuant to Article 5 of Transocean’s Articles
of Association, the board of directors is authorized to withdraw or limit the preemptive rights of the shareholders with
respect to a maximum of 107,848,756 shares and to allot them to individual shareholders or third parties with respect
to the issuance of shares from authorized capital if:

●

●

●

● the  issue  price  of  the  new  shares  is  determined  by  reference  to  the  market

price;

● the  shares  are  issued  in  connection  with  the  acquisition  of  an  enterprise  or
participations  or  any  part  of  an  enterprise  or  participations,  the  financing  or
refinancing of any such transactions or the financing of our new investment
plans;

● the  shares  are  issued  in  connection  with  the  intended  broadening  of  the
shareholder  constituency  of  Transocean  in  certain  financial  or  investor
markets,  for  the  purposes  of  the  participation  of  strategic  partners,  or  in
connection  with  the  listing  of  the  shares  on  domestic  or  foreign  stock
exchanges;

2

●

●

● in  connection  with  a  placement  or  sale  of  shares,  the  grant  of  an  over-
allotment option of up to 20% of the total number of shares in a placement or
sale of shares to the initial purchasers or underwriters; or

● for  the  participation  of  directors,  members  of  our  executive  management
team,  employees,  contractors,  consultants  and  other  persons  performing
services for our benefit or the benefit of any of our subsidiaries.

Conditional Share Capital. In connection with the issuance of bonds, notes, warrants or other financial instruments or
contractual  obligations  convertible  into  or  exercisable  or  exchangeable  for  our  shares,  the  preemptive  rights  of
shareholders are excluded and the board of directors is authorized to withdraw or limit the advance subscription rights
of shareholders in connection with the issuance of bonds, notes, warrants or other securities or contractual obligations
convertible  into  or  exercisable  or  exchangeable  for  our  shares  if  the  issuance  is  for  purposes  of  financing  or
refinancing the acquisition of an enterprise or business, parts of an enterprise, participations or investments, or if the
issuance occurs in national or international capital markets or through a private placement.

If the advance subscription rights are withdrawn or limited:

●

●

●

● the  respective  financial  instruments  or  contractual  obligations  will  be  issued

or entered into at market conditions;

● the  conversion,  exchange  or  exercise  price,  if  any,  for  instruments  or
obligations  will  be  set  with  reference  to  the  market  conditions  prevailing  at
the  date  on  which  the  instruments  or  obligations  are  issued  or  entered  into;
and

● the  instruments  or  obligations  may  be  converted,  exercised  or  exchanged

during a maximum period of 30 years.

The preemptive rights and the advance subscription rights of shareholders are excluded with respect to shares, bonds,
notes,  warrants  or  other  securities  or  contractual  obligations  issued  from  our  conditional  share  capital  to  directors,
members of executive management, employees, contractors, consultants or other persons providing services to us or
any of our subsidiaries.

Dividends and Other Distributions

Under the Swiss Code, dividends may be paid out only if we have sufficient distributable profits from the previous
fiscal year, or if we have freely distributable reserves (including statutory capital contribution reserves, which are also
referred to as additional paid-in capital), each as will be presented on our audited annual standalone statutory balance
sheet or an audited interim standalone statutory balance sheet. The affirmative vote of shareholders holding a majority
of  the  votes  cast  at  a  general  meeting  of  shareholders  (not  counting  abstentions  and  blank  or  invalid  ballots)  must
approve  the  distribution  of  dividends.  The  board  of  directors  may  propose  to  shareholders  that  a  dividend  or  other
distribution be paid but cannot itself authorize the distribution.

Payments out of our share capital (in other words, the aggregate par value of our registered share capital) in the form
of dividends are not allowed; however, payments out of registered share capital may be made by way of a par value
reduction. Such a par value reduction requires the approval of shareholders holding a majority of the votes cast at the
general  meeting  of  shareholders  (not  counting  abstentions  and  blank  or  invalid  ballots).  A  special  audit  report  must
confirm  that  claims  of  our  creditors  remain  fully  covered  despite  the  reduction  in  the  share  capital  recorded  in  the
commercial  register.  A  licensed  audit  expert  must  prepare  the  audit  report  and  be  present  at  the  general  meeting  of
shareholders  that  adopts  the  resolution.    The  board  of  directors  must  further  give  public  notice  of  the  par  value
reduction resolution in the Swiss Official Gazette of Commerce and notify creditors that they may request, within one
month of the public notice, satisfaction of or security for their claims. The notification may be given before or after the
general meeting of shareholders resolving on the par value reduction.

3

Under the Swiss Code, if our general reserves amount to less than 20% of our share capital recorded in the commercial
register (i.e., 20% of the aggregate par value of our registered capital), then at least 5% of our annual profit must be
allocated to the statutory profit reserve. The Swiss Code and our Articles of Association permit us to accrue additional
general reserves. In addition, if we acquire our own shares, we are required to account for these shares, if acquired by
our parent company Transocean Ltd., as a negative item in our shareholders’ equity or, if these shares are acquired by
one of our subsidiaries, to create a special reserve, in each case on our audited annual or interim standalone statutory
balance  sheet  in  the  amount  of  the  purchase  price  of  the  shares  repurchased  by  our  parent  or  our  subsidiary.  The
negative  item  in  our  shareholders’  equity  or  the  reserve  amount  would  effectively  reduce  our  capacity  to  declare
dividends or effect subsequent repurchases of our shares.

Swiss companies generally must maintain a separate company, stand-alone “statutory” balance sheet for the purpose
of, among other things, determining the amounts available for the return of capital to shareholders, including by way of
a distribution of dividends. Our auditor must confirm that a proposal made by the board of directors to shareholders
regarding the appropriation of our available earnings or the distribution of freely distributable reserves conforms to the
requirements of the Swiss Code and our Articles of Association. Dividends are usually due and payable shortly after
the shareholders have passed a resolution approving the payment, but shareholders may also resolve at the annual or
extraordinary  general  meeting  of  shareholders  to  pay  dividends  in  quarterly  or  other  installments.  Our  Articles  of
Association  provide  that  dividends  that  have  not  been  claimed  within  five  years  after  the  payment  date  become  our
property and are allocated to the general reserves. Dividends paid out of distributable profits or distributable general
reserves are subject to Swiss withholding tax, all or part of which can potentially be reclaimed under the relevant tax
rules in Switzerland or double taxation treaties concluded between Switzerland and foreign countries. Distributions to
shareholders in the form of a par value reduction and distributions out of capital contribution reserves are not subject to
the Swiss federal withholding tax.

Dividends, if declared by us, are expected to be declared, subject to applicable limitations under Swiss law, in U.S.
dollars,  or  in  Swiss  francs,  and  shareholders  may  be  given  the  right  to  elect  to  be  paid  any  such  dividends  in  U.S.
dollars  or  Swiss  francs.  Distribution  through  a  reduction  in  the  par  value  of  the  shares  must  be  declared  in  Swiss
francs; however, shareholders may be provided with the option to elect to be paid in U.S. dollars or Swiss francs.

Repurchases of Shares

The Swiss Code limits our ability to hold or repurchase our own shares. We and our subsidiaries may only repurchase
shares if and to the extent that sufficient freely distributable equity capital is available, as described above under “—
Dividends and Other Distributions.” The aggregate par value of all of our shares held by us and our subsidiaries may
not exceed 10% of the registered share capital. However, we may repurchase our own shares beyond the statutory limit
of 10% if the shareholders have authorized the board of directors at a general meeting of shareholders to repurchase
shares  in  an  amount  greater  than  10%  and  the  repurchased  shares  are  dedicated  for  cancellation.  Any  shares
repurchased pursuant to such an authorization will then be cancelled based on a resolution of shareholders adopted at a
general  meeting  of  shareholders  following  the  approval  of  shareholders  holding  a  majority  of  the  votes  cast  at  the
general meeting. Repurchased shares held by us or our subsidiaries do not carry any rights to vote at a general meeting
of shareholders but are, unless otherwise resolved by our shareholders at a general meeting, entitled to the economic
benefits generally associated with the shares.

General Meetings of Shareholders

The general meeting of shareholders is our supreme corporate body. Ordinary and extraordinary shareholders meetings
may be held. Among other things, the following powers will be vested exclusively in the shareholders meeting:

●

●

● adoption and amendment of our Articles of Association;

● the annual election of the chairman of the board of directors, the members of
the  board  of  directors,  the  members  of  the  compensation  committee  of  the
board of directors, the auditor and the independent proxy;

4

●

●

●

●

●

●

●

●

● approval  of  the  annual  management  report,  the  stand-alone  statutory

financial statements and the consolidated financial statements;

● appropriation of the annual profit shown on our annual stand-alone statutory

balance sheet, in particular the distribution of any dividends;

● the determination of interim dividends and the approval of interim statutory

financial statements required for such purposes;

● the resolution regarding the repayment of the statutory capital reserves;

● the combination of shares (“reverse stock split”);

● discharge  of  the  members  of  the  board  of  directors  and  the  executive
management  team  from  liability  for  business  conduct  during  the  previous
fiscal year(s) to the extent such conduct is known to the shareholders;

● ratification of the maximum aggregate amounts of compensation of the board

of directors and the executive management team;

a

defined 
in  our  Articles  of
Association);

● delisting  of  shares  from  a  stock

exchange;

● the approval of the report on non-
financial  matters  pursuant 
to
article  964c  of  the  Swiss  Code;
and

● any other resolutions that are submitted to a general meeting of shareholders pursuant to
law,  our  Articles  of  Association  or  by  voluntary  submission  by  the  board  of  directors
(unless a matter is within the exclusive competence of the board of directors pursuant to
the Swiss Code).

Notice and Proxy Statements

Under  the  Swiss  Code  and  our  Articles  of  Association,  we  must  hold  an  annual,  ordinary  general  meeting  of
shareholders within six months after the end of our fiscal year for the purpose, among other things, of approving the
annual  financial  statements  and  the  annual  management  report,  the  annual  election  of  our  chair  of  the  board  of
directors,  the  members  of  the  board  of  directors,  the  members  of  the  compensation  committee  of  our  board  of
directors,  our  auditor  and  our  independent  proxy,  and  the  ratification  of  the  maximum  aggregate  amount  of
compensation of the board of directors and the executive management team. The invitation to general meetings must
be  published  in  the  Swiss  Official  Gazette  of  Commerce  at  least  20  calendar  days  prior  to  the  date  of  the  relevant
general meeting of shareholders. The notice of a meeting must state the items on the agenda and the proposals of the
board  of  directors  and  of  the  shareholders  who  requested  that  a  shareholders  meeting  be  held  or  that  an  item  be
included on the agenda and, in case of elections, the names of the nominated candidates. The notice must also include
a short explanation of the items and proposals on the agenda of the general meeting. No resolutions may be passed at a
shareholders meeting concerning agenda items for which proper notice was not given. This does not apply, however, to
proposals made during a shareholders meeting to convene an extraordinary shareholders meeting, to initiate a special
investigation or to elect the statutory auditor. No previous notification will be required for proposals concerning items
included on the agenda or for debates as to which no vote is taken.

Annual  general  meetings  of  shareholders  are  convened  by  the  board  of  directors  or,  under  certain  circumstances
required  by  law,  the  auditor.  Except  as  otherwise  authorized  in  our  Articles  of  Association,  a  general  meeting  of
shareholders can be held anywhere in Switzerland. General meetings that are held virtually only require a special

5

authorization  in  a  company's  articles  of  association.  Our  current  Articles  of  Association  do  not  include  such  an
authorization.

We expect to set the record date for each general meeting of shareholders on a date not more than 20 calendar days
prior  to  the  date  of  each  general  meeting  and  announce  the  date  of  the  general  meeting  of  shareholders  prior  to  the
record date.

Extraordinary General Meetings of Shareholders

An  extraordinary  general  meeting  may  be  called  upon  the  resolution  of  the  board  of  directors  or,  under  certain
circumstances required by law, the auditor. In addition, the board of directors is required to convene an extraordinary
general  meeting  of  shareholders  if  so  resolved  by  the  general  meeting  of  shareholders,  or,  according  to  our  current
Articles of Association, if so requested by one or more shareholders holding an aggregate of at least 10% of the share
capital recorded in the commercial register or according to the views expressed in legal writing, which is persuasive
authority in Switzerland, holding shares with an aggregate par value of CHF 1 million, specifying the items for the
agenda  and  their  proposals.  Under  the  new  corporate  law  as  reflected  in  the  Swiss  Code,  effective  as  of  January  1,
2023, the threshold applicable to the shareholders' right to request that a general meeting be convened will be reduced
from 10% (as in our current Articles of Association) to 5% of the share capital or votes by December 31, 2024, unless
our Articles of Association are amended to reflect such reduction before then. Upon such a shareholder request, the
board of directors must make the publication necessary to convene a general meeting within 60 calendar days.

In addition, if it appears from the annual stand-alone statutory balance sheet that half of the sum of our share capital,
the non-distributable statutory capital reserves and the statutory profit reserves are not covered by our assets, the board
of directors is required to take measures to remedy the capital loss situation and , where necessary, request the general
meeting to approve such measures as are within its authority.

Agenda Requests

Under our Articles of Association, any shareholder may request that an item be included on the agenda of a general
meeting  of  shareholders.  Such  shareholder  may  also  nominate  one  or  more  directors  for  election.  A  request  for
inclusion  of  an  item  on  the  agenda  or  a  nominee  must  be  made  in  writing  at  least  30  calendar  days  prior  to  the
anniversary  date  of  the  proxy  statement  in  connection  with  our  last  general  meeting  of  shareholders;  provided,
however,  that  if  the  date  of  the  general  meeting  of  shareholders  is  more  than  30  calendar  days  before  or  after  the
anniversary date of the last annual general meeting of shareholders, such request must instead be made by the tenth
calendar  day  following  the  date  on  which  we  have  made  public  disclosure  of  the  date  of  the  general  meeting  of
shareholders. The request must specify in writing the relevant agenda items and motions, together with evidence of the
required shares recorded in the share register, as well as any other information as would be required to be included in a
proxy statement pursuant to the rules of the Securities and Exchange Commission.

Under the Swiss Code, a general meeting of shareholders for which a notice of meeting has been duly published may
not be adjourned without publishing a new notice of meeting.

Our  annual  report,  our  standalone  and  consolidated  financial  statements,  the  auditors'  reports  thereon,  our
compensation report pursuant to Swiss law and the auditor’s reports thereon must be made available no later than 20
calendar days prior to the annual general meeting of shareholders. If these documents are not accessible electronically,
each shareholder may request that these documents be sent to it in due course.

Voting

Each  of  our  shares  carries  one  vote  at  a  general  meeting  of  shareholders.  Voting  rights  may  be  exercised  by
shareholders  registered  in  our  share  register  or  by  a  duly  appointed  proxy  of  a  registered  shareholder  (including  the
independent proxy), which proxy need not be a shareholder. Our Articles of Association do not limit the number of
shares that may be voted by a single shareholder. Shareholders wishing to exercise their voting rights who hold their
shares through a bank, broker or other nominee should follow the instructions provided by such bank, broker or other
nominee or, absent instructions, contact such bank, broker or other nominee for instructions. Shareholders holding

6

their shares through a bank, broker or other nominee will not automatically be registered in our share register. If any
such  shareholder  wishes  to  be  registered  in  our  share  register,  such  shareholder  should  contact  the  bank,  broker  or
other nominee through which it holds our shares.

Treasury shares, whether owned by us or one of our majority-owned subsidiaries, will not be entitled to vote at general
meetings of shareholders.

Our Articles of Association do not provide for cumulative voting for the election of directors.

Pursuant to our Articles of Association, the shareholders generally pass resolutions by the affirmative vote of a relative
majority of the votes cast at the general meeting of shareholders (broker nonvotes, abstentions and blank and invalid
ballots will be disregarded), unless otherwise provided by law or our Articles of Association. However, our Articles of
Association provide that directors may be elected at a general meeting of shareholders by a plurality of the votes cast
by  the  shareholders  present  in  person  or  by  proxy  at  the  meeting.  Our  Corporate  Governance  Guidelines  have  a
majority vote policy that provides that the board may nominate only those candidates for director who have submitted
an irrevocable letter of resignation which would be effective upon and only in the event that (1) such nominee fails to
receive  a  sufficient  number  of  votes  from  shareholders  in  an  uncontested  election  and  (2)  the  board  accepts  the
resignation following such failure. If a nominee who has submitted such a letter of resignation does not receive more
votes cast “for” than “against” the nominee’s election, the corporate governance committee must promptly review the
letter  of  resignation  and  recommend  to  the  board  whether  to  accept  the  tendered  resignation  or  reject  it.  The  board
must  then  act  on  the  corporate  governance  committee’s  recommendation  within  90  days  following  the  shareholder
vote. The board must promptly disclose its decision regarding whether or not to accept the nominee’s resignation letter.

The  acting  chair  may  direct  that  resolutions  and  elections  be  held  by  use  of  an  electronic  voting  system.  Electronic
resolutions  and  elections  are  considered  equal  to  resolutions  and  elections  taken  by  way  of  a  written  ballot.  Virtual
only meetings may only be held if the articles of association expressly authorize such a form of the general meeting.
Our Articles of Association do not currently include such an authorization.

The  Swiss  Code  and/or  our  Articles  of  Association  require  the  affirmative  vote  of  at  least  two-thirds  of  the  voting
rights and a majority of the par value of the shares, each as represented at a general meeting to approve, among other
things, the following matters:

●

●

●

●

●

● the amendment to or the modification of the purpose clause in our Articles of

Association;

● the combination of shares ("reverse stock split");

● the creation or cancellation of shares with privileged voting rights;

● the restriction on the transferability of shares or cancellation thereof;

● the  restriction  on  the  exercise  of  the  right  to  vote  or  the  cancellation

thereof;

● changes to our authorized or conditional share capital;

● the change of currency of our share capital;

● the delisting of our shares from a stock exchange;

● an increase in the share capital through (1) the conversion of capital surplus,

●

(2) a contribution in kind, or (3) a grant of special privileges;

7

●

●

●

●

●

● the limitation on or withdrawal of preemptive rights;

● a change in our registered office;

● the conversion of registered shares into bearer shares and vice versa; and

● the introduction of an arbitration agreement in our Articles of Association;

● our dissolution.

The same qualified voting requirements apply to resolutions in relation to transactions among corporations based on
Switzerland’s  Federal  Act  on  Mergers,  Demergers,  Transformations  and  the  Transfer  of  Assets  and  Liabilities  (the
“Merger Act”), including a merger, demerger or conversion of a corporation (other than a cash-out or certain squeeze-
out mergers, in which minority shareholders of the company being acquired may be compensated in a form other than
through shares of the acquiring company, for instance, through cash or securities of a parent company of the acquiring
company or of another company—in such a merger, an affirmative vote of 90% of the outstanding shares is required).
Swiss law may also impose this supermajority voting requirement in connection with the sale of “all or substantially
all of our assets” by us. See “—Compulsory Acquisitions; Appraisal Rights” below.

Our Articles of Association require the affirmative vote of at least two-thirds of the shares entitled to vote at a general
meeting to approve the following matters:

● the removal of a serving member of the board of directors;

● any changes to Article 14, paragraph 1 specifying advance notice of proposal requirements;

● any changes to Article 18 specifying vote requirements for resolutions and elections;

● any changes to Article 20, paragraph 2 specifying supermajority vote requirements;

● any changes to Article 21 specifying quorum requirements;

● any changes to Article 22 specifying the number of members of the board of directors;

● any changes to Article 23 specifying the term of the board of directors; and

● any changes to Article 24 specifying the organization of the board of directors and the indemnification

provisions for directors and officers.

Our Articles of Association require the affirmative vote of holders of the number of our shares at least equal to the sum
of (A) two-thirds of the number of all shares outstanding and entitled to vote at a general meeting, plus (B) a number
of shares outstanding and entitled to vote at the general meeting that is equal to one-third of the number of shares held
by  an  interested  shareholder,  for  us  to  engage  in  any  business  combination  with  an  interested  shareholder  (as  those
terms  are  defined  in  our  Articles  of  Association)  and  for  the  amendment  of  the  provisions  in  our  Articles  of
Association relating to this shareholder approval requirement.

Quorum for General Meetings

The presence of shareholders, in person or by proxy, holding at least a majority of the shares entitled to vote at the time
when the general meeting proceeds to business is generally the required presence for a quorum for the transaction of
business at a general meeting of shareholders. However, the presence of shareholders, in person or by proxy, holding at
least two-thirds of the share capital recorded in the commercial register at the time when the general meeting proceeds
to  business  is  the  required  presence  for  a  quorum  to  adopt  a  resolution  to  amend,  vary,  suspend  the  operation  of  or
cause any of the following provisions of our Articles of Association to cease to apply:

8

● Article 18—which relates to proceedings and procedures at general meetings;

● Article 19(g)—which relates to business combinations with interested shareholders;

● Article 20—which sets forth the level of shareholder approval required for certain matters;

● Article 21—which sets forth the quorum at a general meeting required for certain matters, including the

removal of a serving member of the board of directors; and

● Articles 22, 23 and 24—which relate to the size and the organization of the board of directors, the term of

directors and the indemnification provisions for directors and officers.

Additionally, shareholders present, in person or by proxy, holding at least two-thirds of the share capital recorded in
the commercial register at the time when the general meeting proceeds to business constitute the required presence for
a quorum at a general meeting to adopt a resolution to remove a serving director.

Under the Swiss Code, the board of directors has no authority to waive quorum requirements stipulated in the Articles
of Association.

Inspection of Books and Records

Under the Swiss Code, a shareholder has a right to inspect the share register with regard to his, her or its own shares
and  otherwise  to  the  extent  necessary  to  exercise  his,  her  or  its  shareholder  rights.  No  other  person  has  a  right  to
inspect  the  share  register.  The  books  and  correspondence  of  a  Swiss  company  may  be  inspected  with  the  express
authorization  of  the  general  meeting  of  shareholders  or  by  resolution  of  the  board  of  directors  and  subject  to  the
safeguarding of the company’s business secrets. At a general meeting of shareholders, any shareholder is entitled to
request information from the board of directors concerning the affairs of the company. Shareholders may also ask the
auditor questions regarding its audit of the company. The board of directors and the auditor must answer shareholders’
questions to the extent necessary for the exercise of shareholders’ rights and subject to prevailing business secrets or
other of our material interests.

Special Investigation

If the shareholders’ inspection and information rights as outlined above prove to be insufficient, any shareholder may
propose to the general meeting of shareholders that a special independent commissioner investigate specific facts in a
special investigation. If the general meeting of shareholders approves the proposal, we or any shareholder may, within
30  calendar  days  after  the  general  meeting  of  shareholders,  request  the  court  at  our  registered  office  to  appoint  a
special commissioner. If the general meeting of shareholders rejects the request, one or more shareholders representing
at least 5% of the share capital or the votes may request, within three months after the general meeting, the court to
appoint  a  special  independent  commissioner.  The  court  will  issue  such  an  order  if  the  petitioners  can  demonstrate
prima facie that the board of directors, any member of our board of directors or one of our officers infringed the law or
our  Articles  of  Association  and  thereby  damaged  the  company  or  the  shareholders.  The  costs  of  the  investigation
would generally be allocated to us and only in exceptional cases to the petitioners.

Compulsory Acquisitions; Appraisal Rights

Swiss companies that undertake business combinations and other transactions that are binding on all shareholders are
governed  by  the  Merger  Act.  A  statutory  merger  or  demerger  requires  that  at  least  two-thirds  of  the  shares  and  a
majority of the par value of the shares, each as represented at the general meeting of shareholders, vote in favor of the
transaction. Under the Merger Act, a “demerger” may take two forms:

● a  legal  entity  may  divide  all  of  its  assets  and  transfer  such  assets  to  other  legal  entities,  with  the
shareholders  of  the  transferring  entity  receiving  equity  securities  in  the  acquiring  entities  and  the
transferring entity dissolving upon deregistration in the commercial register; or

9

● a legal entity may transfer all or a portion of its assets to other legal entities, with the shareholders of the

transferring entity receiving equity securities in the acquiring entities.

If a transaction under the Merger Act receives all of the necessary consents, all shareholders would be compelled to
participate in the transaction. See “—Voting” above.

Swiss  companies  may  be  acquired  by  an  acquirer  through  the  direct  acquisition  of  the  share  capital  of  the  Swiss
company.  With  respect  to  corporations  limited  by  shares,  such  as  Transocean,  the  Merger  Act  provides  for  the
possibility of a so-called “cash-out” or “squeeze-out” merger if the acquirer controls 90% of the outstanding shares. In
these  limited  circumstances,  minority  shareholders  of  the  company  being  acquired  may  be  compensated  in  a  form
other than through shares of the acquiring company (for instance, through cash or securities of a parent company of the
acquiring company or of another company). For business combinations effected in the form of a statutory merger or
demerger  and  subject  to  Swiss  law,  the  Merger  Act  provides  that  if  the  equity  rights  have  not  been  adequately
preserved  or  compensation  payments  in  the  transaction  are  unreasonable,  a  shareholder  may  request  the  competent
court to determine a reasonable amount of compensation.

In addition, under Swiss law, the sale of “all or substantially all of our assets” by us may require a resolution of the
general meeting of shareholders passed by holders of at least two-thirds of the voting rights and a majority of the par
value of the shares, each as represented at the general meeting of shareholders. Whether or not a shareholder resolution
is required depends on the particular transaction, including whether the following test is satisfied:

● the  company  sells  a  core  part  of  its  business,  without  which  it  is  economically  impracticable  or

unreasonable to continue to operate the remaining business;

● the company’s assets, after the divestment, are not invested in accordance with the company’s statutory

business purpose; and

● the  proceeds  of  the  divestment  are  not  earmarked  for  reinvestment  in  accordance  with  the  company’s
business  purpose  but,  instead,  are  intended  for  distribution  to  shareholders  or  for  financial  investments
unrelated to the company’s business.

If all of the foregoing apply, a shareholder resolution would likely be required.

Switzerland, and operates under the Swiss Code as a stock corporation (Aktiengesellschaft). Transocean is recorded in
the  Commercial  Register  of  the  Canton  of  Zug  with  the  registration  number  CHE-114.461.224.  Transocean’s  fiscal
year is the calendar year.

The address of Transocean’s registered office is Transocean, Turmstrasse 30, 6312 Steinhausen, Switzerland, and the
telephone number at that address is +41 (0)41 749 0500.

Corporate Purpose

Transocean is the parent holding company of the Transocean group. Pursuant to its Articles of Association, its business
purpose  is  to  acquire,  hold,  manage,  exploit  and  sell,  whether  directly  or  indirectly,  participations  in  businesses  in
Switzerland  and  outside  of  Switzerland,  in  particular  in  businesses  that  are  involved  in  offshore  contract  drilling

Switzerland and outside of Switzerland.

Duration and Liquidation

10

Our  Articles  of  Association  do  not  limit  our  duration.  Under  Swiss  law,  we  may  be  dissolved  at  any  time  by  a
resolution adopted at a general meeting of shareholders, which must be passed by the affirmative vote of holders of at
least two thirds of voting rights and an absolute majority of the par value of the shares, each as represented (in person
or by proxy) at the general meeting. Dissolution and liquidation by court order is possible if (1) we become bankrupt
or (2) shareholders holding at least 10% of our share capital so request for valid reasons. Under Swiss law, any surplus
arising out of liquidation (after the settlement of all claims of all creditors) is distributed in proportion to the paid-up
par value of shares held. The amount exceeding the par value of the share is subject to Swiss withholding tax of 35%.
Our shares carry no privilege with respect to such liquidation surplus.

Uncertificated Shares

Our shares have been issued in uncertificated form in accordance with article 973c of the Swiss Code as uncertificated
securities, which have been registered with Computershare, and constitute intermediated securities within the meaning
of  the  Swiss  Federal  Act  on  Intermediated  Securities.  In  accordance  with  article  973c  of  the  Code,  Transocean
maintains a register of uncertificated securities (Wertrechtebuch).

Stock Exchange Listing

Our shares are listed and trade on the NYSE under the symbol “RIG.”

No Sinking Fund

The shares have no sinking fund provisions.

No Liability for Further Calls or Assessments

The shares that have been issued to date are duly and validly issued, fully paid and nonassessable.

No Redemption and Conversion

The  shares  are  not  convertible  into  shares  of  any  other  class  or  series  or  subject  to  redemption  either  by  us  or  the
holder of the shares.

Transfer and Registration of Shares

We  have  not  imposed  any  restrictions  applicable  to  the  transfer  of  our  shares,  other  than  the  requirement  that  an
acquirer of shares expressly declares to have acquired the shares in its own name and for its own account. Our share
register  is  maintained  by  Computershare,  which  acts  as  transfer  agent  and  registrar.  The  share  register  reflects  only
record owners of our shares. Swiss law does not recognize fractional share interests.

Description of the 2023 Exchangeable Bonds

Introductory  note:  The  following  is  a  description  of  the  Exchangeable  Bonds  as  of  December  31,  2022.  The
Exchangeable Bonds were subsequently repaid as of their maturity date of January 30, 2023.

The following is a summary and does not purport to be complete. It is subject to, and qualified by reference to, all of
the provisions of the Exchangeable Bonds and the indenture among Transocean Inc. (“TINC”), as issuer, Transocean
Ltd. (“Transocean”), as guarantor, and Computershare Trust Company, N.A. and Computershare Trust Company of
Canada, as co-trustees, dated January 30, 2018 (the “indenture”). We encourage you to read the indenture for
additional information. In this summary, “we,” “our” and “us” means TINC, as issuer of the Exchangeable Bonds,
and “guarantor” means Transocean, as guarantor of the Exchangeable Bonds, unless, in each case, we indicate
otherwise or the context indicates otherwise. General

11

The  Exchangeable  Bonds  are  our  general  unsecured  and  senior  obligations,  and  are  exchangeable  into  Transocean’s
Shares  as  described  under  “—Exchange  Rights”  below.  The  Exchangeable  Bonds  are  fully  and  unconditionally
guaranteed on a senior unsecured basis by the guarantor. The Exchangeable Bonds will mature on January 30, 2023.

The  Exchangeable  Bonds  pay  cash  interest  at  an  annual  rate  of  0.5%  on  the  principal  amount  of  the  Exchangeable
Bonds  to,  but  excluding,  the  next  scheduled  interest  payment  date  until  January  30,  2023.  Interest  is  payable  semi-
annually  in  arrears  on  January  30  and  July  30  of  each  year,  to  holders  of  record  at  the  close  of  business  on  the
preceding January 15 and July 15, respectively. Accrued interest is computed on the basis of a 360-day year composed
of twelve 30-day months. In the event of the repurchase by us at the option of the holder of an Exchangeable Bond,
interest ceases to accrue on the Exchangeable Bonds under the terms of and subject to the conditions of the indenture.

Any  amounts  on  the  Exchangeable  Bonds  that  are  payable  but  not  punctually  paid  or  provided  for  (“defaulted
amounts”) will cease to be payable to the holder of the Exchangeable Bonds on the relevant payment date but will
accrue interest per annum at the rate borne by the Exchangeable Bonds, subject to applicable law, from, and including,
the relevant payment date. We may elect to pay the defaulted amounts and any interest accrued (i) to the holders of the
Exchangeable Bonds as of the close of business on a special record date, which will be not more than 15 days and not
less  than  10  days  prior  to  the  date  of  our  proposed  payment  of  such  defaulted  amounts  or  (ii)  in  any  other  lawful
manner not inconsistent with the requirements of the New York Stock Exchange, or any other securities exchange or
automated quotation system on which the Exchangeable Bonds may be listed or designated for trading.

The indenture does not contain any financial covenants or any restrictions on the payment of dividends, the making of
investments,  the  incurrence  of  indebtedness,  the  granting  of  liens  or  mortgages,  or  the  issuance  or  repurchase  of
securities  by  us.  The  indenture  does  not  contain  any  covenants  or  other  provisions  to  protect  holders  of  the
Exchangeable  Bonds  in  the  event  of  a  highly  leveraged  transaction  or  a  fundamental  change,  except  to  the  extent
described under “—Exchange Rights—Increased Exchange Rate in Connection with Fundamental Changes” and “—
Repurchase Rights Following Fundamental Change or Tax Event” below.

As  of  December  31,  2022,  approximately  $49  million  aggregate  principal  amount  of  Exchangeable  Bonds  was
outstanding.

The Exchangeable Bonds are not subject to a sinking fund provision and are not be subject to defeasance or covenant
defeasance under the indenture.

Guarantee

Our obligations under the indenture, including the repurchase obligations resulting from a fundamental change or tax
event, are fully and unconditionally guaranteed, on a senior unsecured basis by the guarantor.

The guarantor’s obligations under the guarantee are limited to the maximum amount as, after giving effect to all other
contingent  and  fixed  liabilities  of  the  guarantor,  will  result  in  the  guarantor’s  obligation  under  the  guarantee  not
constituting  a  fraudulent  transfer  or  conveyance  for  purposes  of  any  Bankruptcy  Law,  the  Uniform  Fraudulent
Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law.

The  Exchangeable  Bonds  are  not  obligations  of,  or  guaranteed  by,  any  of  our  or  the  guarantor’s  existing  or  future
subsidiaries.

Ranking/Additional Debt

The Exchangeable Bonds are our general unsecured obligations and rank:

(1) senior in right of payment to all of our existing and future subordinated indebtedness;

(2) equal in right of payment with all of our existing and future unsecured senior indebtedness;

12

(3)  effectively  junior  in  right  of  payment  to  all  of  our  existing  and  future  secured  indebtedness  to  the  extent  of  the
value of the assets securing such indebtedness; and

(4) structurally subordinated to all secured and unsecured liabilities of our subsidiaries.

The  guarantee  is  a  senior  unsecured  obligation  of  the  guarantor  and  will  rank  equally  in  right  of  payment  with  the
guarantor’s other senior unsecured indebtedness from time to time outstanding.

The indenture does not limit the amount of debt that we or any of our subsidiaries may incur or issue, and it does not
restrict  transactions  between  us  and  our  affiliates  or  dividends  and  other  distributions  by  us  or  our  subsidiaries.  As
described under “—General,” we may issue additional Exchangeable Bonds under the indenture from time to time.

Exchange Rights

General

Unless  the  Exchangeable  Bonds  are  previously  repurchased,  holders  may  exchange  their  Exchangeable  Bonds  for
Shares  at  any  time  prior  to  the  close  of  business  on  the  business  day  immediately  preceding  the  maturity  date.  The
initial  exchange  rate  of  the  Exchangeable  Bonds  is  97.29756  Shares  per  $1,000  principal  amount  of  Exchangeable
Bonds. The exchange rate is subject to change as described below under “—Increased Exchange Rate in Connection
with a Fundamental Change,” “—Increased Exchange Rate in Connection with a Tax Event” and “—Exchange Rate
Adjustments.” A holder may exchange fewer than all of such holder’s Exchangeable Bonds so long as the portion of
Exchangeable Bonds exchanged is an integral multiple of $1,000 principal amount.

We  will  satisfy  our  exchange  obligation  through  delivery  by  the  guarantor  of  the  Shares.  See  “—Settlement  Upon
Exchange.” Upon exchange of an Exchangeable Bond, a holder will not receive any cash payment of interest (unless
such  exchange  occurs  between  a  regular  record  date  and  the  interest  payment  date  to  which  it  relates  and  the
exchanging  holder  held  the  Exchangeable  Bonds  on  that  record  date),  and  we  will  not  adjust  the  exchange  rate  to
account for accrued and unpaid interest. Accordingly, any accrued but unpaid interest will be deemed to be paid in full
upon exchange, rather than cancelled, extinguished or forfeited.

Holders  of  Exchangeable  Bonds  at  the  close  of  business  on  a  regular  record  date  will  receive  payment  of  interest
payable on the corresponding interest payment date notwithstanding the exchange of such Exchangeable Bonds at any
time after the close of business on the applicable regular record date. Exchangeable Bonds surrendered for exchange
by a holder after the close of business on any regular record date but prior to the next interest payment date must be
accompanied  by  payment  of  an  amount  equal  to  the  interest  that  the  holder  on  the  record  date  is  to  receive  on  the
Exchangeable Bonds; provided, however, that no such payment need be made (1) for exchanges following the regular
record date immediately preceding the maturity date, (2) if we have specified a repurchase date following a tax event
or fundamental change that is after a record date and on or prior to the next interest payment date or (3) only to the
extent  of  overdue  interest,  if  any  overdue  interest  exists  at  the  time  of  exchange  with  respect  to  such  Exchangeable
Bonds. No other payments or adjustments for interest will be made upon exchange.

Holders of the Shares issuable upon exchange, if any, will not be entitled to receive any dividends payable to holders
of  the  Shares  as  of  any  record  time  or  date  before  such  Shares  are  delivered  to  the  holder  upon  exchange  of  such
holder’s Exchangeable Bonds.

If a holder has already delivered a repurchase notice as described under “—Repurchase Rights Following Fundamental
Change or Tax Event” with respect to an Exchangeable Bond, the holder may not surrender that Exchangeable Bond
for exchange until the holder has withdrawn the repurchase notice in accordance with the indenture.

Settlement Upon Exchange

To  exchange  the  Exchangeable  Bonds,  a  holder  of  Exchangeable  Bonds  in  certificated  form  must  deliver  an
irrevocable, duly completed exchange notice, together with the certificated security, to the exchange agent along with
appropriate endorsements and transfer documents, if required, and pay any interest and transfer or similar tax, in each

13

case, if required, and a holder of Exchangeable Bonds in global form must comply with the applicable procedures of
the depositary in effect at the time and pay any interest and transfer or similar tax, in each case, if required. The date a
holder  satisfies  these  requirements  is  called  the  “exchange  date.”  The  form  of  exchange  notice  is  attached  to  the
indenture.

Delivery of the Shares upon exchange will be accomplished by book-entry transfer of the required number of Shares
through The Depository Trust Company, New York, New York (“DTC”). The trustee will initially act as the exchange
agent.

Upon exchange of the Exchangeable Bonds, a holder will receive, for each $1,000 principal amount of Exchangeable
Bonds exchanged, the Shares at the exchange rate in effect on the exchange date. Cash will be delivered in lieu of any
fractional shares. Settlement will occur through the exchange agent on the third business day following the exchange
date (or, if the exchange is in connection with a fundamental change, on the fifth business day following the exchange
date).

The guarantor’s delivery to the holder of the Shares and any cash, if applicable, in settlement as described above will
satisfy our exchange obligation.

Increased Exchange Rate in Connection with a Fundamental Change

If the effective date of any fundamental change occurs prior to the maturity date, and a holder elects to exchange its
Exchangeable  Bonds  during  the  period  commencing  on  such  effective  date  and  ending  on  the  business  day
immediately before the fundamental change repurchase date (the “fundamental change period”), then the guarantor
will increase the exchange rate for the Exchangeable Bonds surrendered for exchange as described below.

We  will  notify  holders  of  any  such  fundamental  change  and  the  anticipated  effective  date  in  accordance  with  the
procedures outlined in the indenture and described in “—Repurchase Rights Following Fundamental Change or Tax
Event” below.

The increased exchange rate applicable to any exchange in connection with a fundamental change due to a change of
control will be determined as follows:

COCER

COCER

OER

EP

c

t

LFER

LFER

OER

EP

c

t

= OER x (1 +(EP x (c/t))), where

= change of control exchange rate

= exchange rate otherwise applicable, before giving effect to increase

= the  number  of  days  from  and  including  the  date  of  the  change  of  control  to  but  excluding  the

maturity date

= the number of days from and including the issue date to but excluding the maturity date

Notwithstanding the foregoing, the increased exchange rate applicable to any exchange in connection with a
fundamental change due to a listing failure event will be determined as follows:

= OER x (1 +(EP x (c/t))), where

= listing failure event exchange rate

= exchange rate otherwise applicable, before giving effect to increase

= 22.50%

= the  number  of  days  from  and  including  the  date  of  the  listing  failure  event  to  but  excluding  the

maturity date

= the number of days from and including the issue date to but excluding the maturity date

For  the  avoidance  of  doubt,  if  a  holder  exchanges  its  Exchangeable  Bonds  prior  to  the  fundamental  change  period,
then, whether or not such fundamental change occurs, the holder will not be entitled to an increased exchange rate in
connection with such fundamental change.

14

A  “fundamental  change”  will  be  deemed  to  have  occurred  at  such  time  after  the  original  issuance  of  the
Exchangeable Bonds when any of the following has occurred:

● a change of control event; or

● a listing failure event.

“Change of control” means the occurrence of any of the following:

A. the sale, lease, transfer, conveyance or other disposition (other than by way of merger, amalgamation or statutory
plan of arrangement or consolidation), in one or a series of related transactions, of all or substantially all of our and our
subsidiaries’ or the guarantor’s and its subsidiaries’ assets, in each case taken as a whole, to any “person” or “group”
(as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) other than to us, the guarantor or one of the
guarantor’s other subsidiaries;

B. the consummation of any transaction (including, without limitation, any merger, amalgamation or statutory plan of
arrangement or consolidation) the result of which is that any “person” or “group” (as such terms are used in Sections
13(d) and 14(d) of the Exchange Act) becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the
Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the guarantor’s or our voting
stock or other voting stock into which the guarantor’s or our voting stock is reclassified, consolidated, exchanged or
changed, measured by voting power rather than number of shares;

C. we or the guarantor consolidate, amalgamate, or enter into a statutory plan of arrangement with, or merge with or
into,  any  “person”  (as  that  term  is  used  in  Section  13(d)(3)  of  the  Exchange  Act),  or  any  person  consolidates,
amalgamates, or enters into a statutory plan of arrangement with, or merges with or into, us or the guarantor, in any
such event pursuant to a transaction in which any of the guarantor’s, our or of such other person’s outstanding voting
stock is converted into or exchanged for cash, securities or other property, other than any such transaction where the
shares  of  our  or  the  guarantor’s  voting  stock  outstanding  immediately  prior  to  such  transaction  constitute,  or  are
converted  into  or  exchanged  for,  voting  stock  representing  more  than  50%  of  the  combined  voting  power  of  the
surviving person immediately after giving effect to such transaction; or

D. the adoption of a plan relating to the guarantor’s or our liquidation or dissolution.

Notwithstanding the foregoing, any holding company whose only significant asset is our capital stock or any of our
direct or indirect parent companies will not itself be considered a “person” or “group” for purposes of clause B above.
Further, notwithstanding the foregoing, no change of control of the guarantor will be deemed to have occurred if at
least  90%  of  the  consideration  for  the  Shares  (excluding  cash  payments  for  fractional  shares)  in  the  transaction  or
transactions otherwise constituting a change of control in respect of the guarantor consist of common stock, ordinary
shares,  American  Depositary  Receipts  or  equivalent  capital  stock  traded  on  the  New  York  Stock  Exchange,  The
NASDAQ Global Select Market or The NASDAQ Global Market, or any successor to any such market, or which will
be  so  traded  when  issued  or  exchanged  in  connection  with  the  transaction  or  transactions  otherwise  constituting  a
change  of  control  in  respect  of  the  guarantor,  and  as  a  result  of  such  transaction  or  transactions,  the  Exchangeable
Bonds  become  exchangeable,  upon  the  conditions  for  exchange  and  actual  exchange  in  accordance  with  the  terms
hereof, into such common stock, ordinary shares, American Depositary Receipts or equivalent capital stock.

“Change of control event” means (a) in the case of a change of control in respect of us, on any date during the 60-day
period (which period will be extended so long as the rating of the Exchangeable Bonds is under publicly announced
consideration  for  a  possible  downgrade  by  any  of  the  rating  agencies  (as  defined  in  the  indenture))  (the  “trigger
period”)  after  the  earlier  of  (1)  the  occurrence  of  a  change  of  control;  or  (2)  public  notice  of  the  occurrence  of  a
change of control or the intention by us to effect a change of control, (i) in the event the Exchangeable Bonds are rated
investment  grade  by  at  least  two  of  the  rating  agencies  prior  to  such  public  notice,  the  rating  of  the  Exchangeable
Bonds by any rating agency shall be below investment grade, (ii) in the event the Exchangeable Bonds are rated below
Investment  Grade  by  at  least  two  of  the  rating  agencies  prior  to  such  public  notice,  the  rating  of  the  Exchangeable
Bonds by any rating agency will be decreased by one or more categories or (iii) the Exchangeable Bonds will not be,
or cease to be, rated by at least one of the rating agencies; provided that, in each case, such event is in whole or in part

15

in  connection  with  the  change  of  control  and  (b)  in  the  case  of  a  change  of  control  in  respect  of  the  guarantor,  the
effective date of such change of control. Notwithstanding the foregoing, no Change of Control Event will be deemed to
have  occurred  in  connection  with  any  particular  Change  of  Control  unless  and  until  such  Change  of  Control  has
actually been consummated.

A “listing  failure  event”  will  be  deemed  to  have  occurred  at  the  time  after  the  Exchangeable  Bonds  are  originally
issued  if  the  Shares  (or  any  other  ordinary  shares,  common  shares  or  American  depositary  shares  underlying  the
Exchangeable Bonds) cease to be listed or quoted on any of The New York Stock Exchange, The NASDAQ Global
Select Market or The NASDAQ Global Market (or any of their respective successors) and are not listed or quoted on
one of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any
of their respective successors) concurrently with such cessation.

Increased Exchange Rate in Connection with a Tax Event

If  a  tax  event  occurs  prior  to  the  maturity  date,  and  a  holder  elects  to  exchange  its  Exchangeable  Bonds  during  the
period commencing on such effective date and ending on the day before the tax event repurchase date (the “tax event
repurchase period”), then the guarantor will increase the exchange rate for the Exchangeable Bonds surrendered for
exchange, as described below.

We will notify holders of any such tax event in accordance with the procedures outlined in the indenture and described
in  “—Fundamental  Change  or  Tax  Event  Requires  Us  to  Repurchase  Exchangeable  Bonds  at  the  Option  of  the
Holder” below.

The increase exchange rate applicable to any exchange in connection with a tax event will be determined as follows:

TEER

TEER

OER

EP

c

t

= OER x (1 +(EP x (c/t))), where

= tax event exchange rate

= exchange rate otherwise applicable, before giving effect to increase

= 22.50%

= the number of days from and including the date of the tax event to but excluding the maturity date

= the number of days from and including the issue date to but excluding the maturity date

For the avoidance of doubt, if a holder exchanges its Exchangeable Bonds prior to the tax event repurchase period,
then, whether or not such tax event occurs, the holder will not be entitled to an increased exchange rate in connection
with such tax event.

A “tax event” will be deemed to have occurred if, at any time after the Exchangeable Bonds are originally issued, (x)
we  reasonably  determine  that  (A)  as  a  result  of  (I)  any  change  in  or  amendment  to  the  laws  or  treaties  (or  any
regulations or rulings promulgated thereunder) of any taxing jurisdiction (as defined below), or (II) any change in the
official  position  regarding  the  application  or  interpretation  of  such  laws,  treaties,  regulations  or  rulings  by  any
legislative body, court, governmental agency or regulatory authority, which change or amendment becomes effective
on  or  after  (1)  the  issue  date,  in  the  case  of  the  Cayman  Islands  or  Switzerland,  or  (2)  the  date  such  jurisdiction
becomes a taxing jurisdiction, in the case of any other taxing jurisdiction, we, the guarantor or any such successor, as
applicable,  have  or  will  become  obligated  to  pay,  on  the  next  succeeding  date  on  which  interest  is  due,  additional
amounts pursuant to the indenture with respect to any of the Exchangeable Bonds; or (B) on or after (1) the issue date,
in the case of the Cayman Islands or Switzerland, or (2) the date such jurisdiction becomes a taxing jurisdiction, in the
case of any other taxing jurisdiction, any action has been taken by any taxing authority of, or any decision has been
rendered by a court of competent jurisdiction in a taxing jurisdiction, including any of those actions specified in (A)
above, whether or not such action was taken or such decision was rendered with respect to us, the guarantor or any
such  successor,  as  applicable,  or  any  change,  amendment,  application  or  interpretation  will  be  officially  proposed,
which in any case, in an opinion of counsel, will result in us, the guarantor or any such successor becoming obligated
to  pay,  on  the  next  succeeding  date  on  which  interest  is  due,  additional  amounts  with  respect  to  any  of  the
Exchangeable Bonds, and, in any such case, we or the guarantor, as applicable, in our business judgment, determine
that such obligation cannot be avoided by the use of reasonable measures available to us or the guarantor; and (y) we
provide notice to all holders of the Exchangeable Bonds and the trustee and the paying agent no less than 20, and no
more than 60, days prior to the

16

earliest date on which we or the guarantor would be obligated to withhold tax resulting from the amendment or change
described in (A) or (B) above were a payment in respect of the Exchangeable Bonds then due that we are designating
such amendment or change as a tax event.

We are not obligated to designate any event as a tax event. As a result, any development described in clause (x) of the
preceding paragraph will not constitute a tax event unless we elect, at our option, to designate it as such. If we declare
a tax event, however, and a tax event offer to repurchase pursuant to the indenture, neither we nor the guarantor will
thereafter be required to pay related additional amounts in respect of the Exchangeable Bonds. See “—Tax Additional
Amounts.”

Exchange Rate Adjustments

The  exchange  rate  will  be  adjusted  for  certain  events,  as  described  below,  except  that  we  will  not  make  any
adjustments to the exchange rate if holders of Exchangeable Bonds have the right to participate (other than in the case
of a share split or share combination or a tender or exchange offer), as a result of holding the Exchangeable Bonds, in
any of the transactions described below without having to exchange their Exchangeable Bonds:

(1) If the guarantor exclusively issues the Shares as a dividend or distribution on the Shares, or effects a subdivision or
combination of the outstanding Shares, the exchange rate will be adjusted based on the following formula:

ER’ = ER0
x

OS’
OS0

ER0

ER’

OS0

OS

= the  exchange  rate  in  effect  immediately  prior  to  the  close  of  business  on  the  record
date of such dividend or distribution, or immediately prior to the open of business on
the date of the subdivision or combination

= the exchange rate in effect immediately after the close of business on such record date

or date of subdivision or combination

= the  number  of  Shares  outstanding  immediately  prior  to  such  subdivision  or

combination

= the  number  of  Shares  that  would  be  outstanding  immediately  after  giving  effect  to

such dividend, distribution, subdivision or combination

Any adjustment made under this paragraph (1) will become effective immediately after the close of business on the
record date for such dividend or distribution, or immediately after the open of business on the date for such subdivision
or combination, as applicable. If any dividend or distribution of the type described in this paragraph (1) is declared but
not so paid or made, the exchange rate will be immediately readjusted, effective as of the date the guarantor’s board of
directors determines not to pay such dividend or distribution, to the exchange rate that would then be in effect if such
dividend or distribution had not been declared.

(2)  If  the  guarantor  issues  to  all  or  substantially  all  holders  of  the  Shares,  rights,  options  or  warrants  (other  than  in
connection with a shareholder rights plan) that allow such holders, for a period ending not more than 45 days after the
announcement date of such issuance, to subscribe for or purchase the Shares at a price per Share that is less than the
average of the last reported sale prices of the Shares for the ten consecutive trading days ending on the business day
immediately  preceding  the  announcement  date  of  such  issuance,  the  exchange  rate  will  be  adjusted  based  on  the
following formula:

ER’ = ER0 x

where,

OS0 + X
OS0 + Y

ER0

ER’
OS0

= the  exchange  rate  in  effect  immediately  prior  to  the  close  of  business  on  the  record

date for such issuance

= the exchange rate in effect immediately after the close of business on such record date

= the number of Shares outstanding immediately prior to the close of business on such

record date

17

X

Y

= the total number of Shares issuable pursuant to such rights, options or warrants

the  number  of  Shares  equal  to  the  aggregate  price  payable  to  exercise  such  rights,
options  or  warrants  divided  by  the  average  of  the  last  reported  sale  prices  of  the
Shares  for  the  ten  consecutive  trading  days  ending  on  the  trading  day  immediately
preceding the announcement of the issuance of such rights, options or warrants

Any  increase  made  under  this  paragraph  (2)  will  become  effective  immediately  after  the  close  of  business  on  the
record date for such issuance. To the extent that the Shares are not delivered after the expiration of such rights, options
or warrants, the exchange rate will be decreased to be the exchange rate that would then be in effect had the increase
with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number
of Shares actually delivered. If such rights, options or warrants are not so issued, the exchange rate will be decreased to
the exchange rate that would then be in effect if such record date for such issuance had not occurred.

(3) If the guarantor distributes the Shares, evidences of its indebtedness, other assets or property of the guarantor or
rights,  options  or  warrants  to  acquire  the  Shares  or  other  securities,  to  all  or  substantially  all  holders  of  the  Shares,
excluding (i) dividends, distributions or issuances as to which an adjustment was effected as described in paragraphs
(1)  or  (2)  above,  (ii)  dividends  or  distributions  paid  exclusively  in  cash  as  to  which  an  adjustment  was  effected  as
described in paragraph (4) below, and (iii) spin-offs (as defined below) as to which the provisions set forth below in
this paragraph (3) apply (any of such Shares, evidences of indebtedness, other assets or property or rights, options or
warrants  to  acquire  the  Shares  or  other  securities,  the  “distributed  property”),  then  the  exchange  rate  will  be
increased based on the following formula:

ER’ = ER0 x

where,

SP0
SP0 - FMV

ER0

ER’
SP0

FMV

= the  exchange  rate  in  effect  immediately  prior  to  the  close  of  business  on  the  record

date for such distribution;

= the exchange rate in effect immediately after the close of business on such record date;

= the  average  of  the  last  reported  sale  prices  of  the  Shares  over  the  10  consecutive
trading  day  period  ending  on,  and  including,  the  trading  day  immediately  preceding
the ex-dividend date for the distribution; and

= the  fair  market  value  (as  determined  by  the  guarantor’s  Board  of  Directors)  of  the
distributed property with respect to each outstanding Share on the ex-dividend date for
the distribution.

Any increase made as described in this paragraph (3) will become effective immediately after the close of business on
the record date for such distribution. If the distribution is not so paid or made, the exchange rate will be decreased to
the exchange rate that would then be in effect if the distribution had not been declared. Notwithstanding the foregoing,
if the fair market value of the Shares is equal to or greater than SP0, in lieu of the foregoing increase, each holder of
Exchangeable Bonds will receive, in respect of each $1,000 principal amount thereof, at the same time and upon the
same terms as holders of the Shares receive the distributed property, the amount and kind of distributed property such
Holder would have received if the holder owned a number of Shares equal to the exchange rate in effect on the ex-
dividend date for the distribution.

With respect to an adjustment as described in this paragraph (3) where there has been a payment of a dividend or other
distribution on the Shares or shares of capital stock of any class or series, or similar equity interest, of or relating to
one  of  the  guarantor’s  subsidiaries  or  other  business  units,  that  are,  or,  when  issued,  will  be,  listed  or  admitted  for
trading  on  a  U.S.  national  securities  exchange  (a  “spin-off”),  the  exchange  rate  will  be  increased  based  on  the
following formula:

ER’ = ER0 x

where,

FMV0 + MP0
MP0

18

ER0

ER’

FMV0

= the  exchange  rate  in  effect  immediately  prior  to  the  close  of  business  on  the  record

date for the spin-off;

= the exchange rate in effect immediately after the close of business on the record date

for the spin-off;

= the average of the last reported sale prices of the capital stock or similar equity interest
distributed  to  holders  of  the  Shares  applicable  to  one  Share  over  the  first  10
consecutive trading day period after, and including, the ex-dividend date of the spin-
off (the “valuation period”); and

MP0

= the average of the last reported sale prices of the Shares over the valuation period.

The increase to the exchange rate under the preceding paragraph will occur at the close of business on the record date
for the spin-off; provided that if the relevant exchange date occurs during the valuation period, references to “10” in
the preceding paragraph will be deemed to be replaced with lesser number of trading days as have elapsed from, and
including, the ex-dividend date of the spin-off to, and including, the exchange date in determining the exchange rate.

For purposes of this paragraph (3), rights, options or warrants distributed by the Guarantor to all holders of the Shares
entitling  them  to  subscribe  for  or  purchase  shares  of  the  Guarantor’s  Capital  Stock,  including  the  Shares  (either
initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or
events (a “trigger event”): (i) are deemed to be transferred with such Shares; (ii) are not exercisable; and (iii) are also
issued in respect of future issuances of the Shares, will be deemed not to have been distributed for purposes of this
paragraph (3) (and no adjustment to the exchange rate under this paragraph (3) will be required) until the occurrence of
the earliest trigger event, whereupon such rights, options or warrants will be deemed to have been distributed and an
appropriate  adjustment  (if  required)  to  the  exchange  rate  will  be  made  under  this  paragraph  (3).  If  any  such  right,
option or warrant, including any such existing rights, options or warrants distributed prior to the date of the indenture,
are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase
different  securities,  evidences  of  indebtedness  or  other  assets,  then  the  date  of  the  occurrence  of  any  and  each  such
event will be deemed to be the date of distribution and record date with respect to new rights, options or warrants with
such rights (in which case the existing rights, options or warrants will be deemed to terminate and expire on such date
without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of
rights,  options  or  warrants,  or  any  trigger  event  or  other  event  (of  the  type  described  in  the  immediately  preceding
sentence)  with  respect  thereto  that  was  counted  for  purposes  of  calculating  a  distribution  amount  for  which  an
adjustment  to  the  exchange  rate  under  this  paragraph  (3)  was  made,  (1)  in  the  case  of  any  such  rights,  options  or
warrants  that  have  all  been  redeemed  or  purchased  without  exercise  by  any  holders  thereof,  upon  such  final
redemption  or  purchase  (x)  the  exchange  rate  will  be  readjusted  as  if  such  rights,  options  or  warrants  had  not  been
issued and (y) the exchange rate will then again be readjusted to give effect to such distribution, deemed distribution or
trigger event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase
price  received  by  a  holder  or  holders  of  the  Shares  with  respect  to  such  rights,  options  or  warrants  (assuming  such
holder  had  retained  such  rights,  options  or  warrants),  made  to  all  holders  of  the  Shares  as  of  the  date  of  such
redemption  or  purchase,  and  (2)  in  the  case  of  such  rights,  options  or  warrants  that  will  have  expired  or  been
terminated without exercise by any holders thereof, the exchange rate will be readjusted as if such rights, options and
warrants had not been issued.

For  purposes  of  paragraphs  (1)  and  (2)  above  and  this  paragraph  (3),  if  any  dividend  or  distribution  to  which  this
paragraph (3) is applicable also includes one or both of:

●

●

● a  dividend  or  distribution  of  the  Shares  to  which  paragraph  (1)  above  is

applicable (the “clause A distribution”); or

● a dividend or distribution of rights, options or warrants to which paragraph

(2) above is applicable (the “clause B distribution”),

then,  in  either  case,  (1)  such  dividend  or  distribution,  other  than  the  clause  A  Distribution  and  the  clause  B
Distribution, will be deemed to be a dividend or distribution to which this paragraph (3) is applicable (the “clause C
distribution”)  and  any  exchange  rate  adjustment  required  by  this  paragraph  (3)  with  respect  to  such  clause  C
distribution  will  then  be  made,  and  (2)  the  clause  A  distribution  and  clause  B  distribution  will  be  deemed  to
immediately  follow  the  clause  C  distribution  and  any  exchange  rate  adjustment  required  by  paragraphs  (1)  and  (2)
above and with respect thereto

19

will then be made, except that, if determined by the guarantor (I) the record date of the clause A distribution and the
clause B distribution will be deemed to be the record date of the clause C distribution and (II) any Shares included in
the clause A distribution or clause B distribution will be deemed not to be “outstanding immediately prior to the close
of business on such record date” within the meaning of paragraph (1) above or “outstanding immediately prior to the
close of business on such record date” within the meaning of paragraph (2) above.

(4) If any cash dividend or distribution is made to all or substantially all holders of Shares, the exchange rate will be
increased based on the following formula:

ER’ = ER0 x

SP0
SP0 - C

where,

ER0

ER’

SP0

C

= the  exchange  rate  in  effect  immediately  prior  to  the  close  of  business  on  the  record

date for such dividend or distribution;

= the exchange rate in effect immediately after the close of business on the record date

for such dividend or distribution;

= the last reported sale price of the Shares on the trading day immediately preceding the

record date for the ex-dividend or distribution;

= the amount in cash per share the guarantor distributes to all or substantially all holders

of the Shares.

Any increase pursuant to this paragraph (4) will become effective immediately after the close of business on the record
date  for  such  dividend  or  distribution.  If  such  dividend  or  distribution  is  not  so  paid,  the  exchange  rate  will  be
decreased, effective as of the date the guarantor’s board of directors determines not to make or pay such dividend or
distribution, to be the exchange rate that would then be in effect if the dividend or distribution had not been declared.
Notwithstanding the foregoing, if C (as defined above) is equal to or greater than SP0 (as defined above), in lieu of the
foregoing  increase,  each  holder  of  Exchangeable  Bonds  will  receive,  for  each  $1,000  principal  amount  of
Exchangeable Bonds, at the same time and upon the same terms as holders of the Shares, the amount of cash that the
Holder would have received if the Holder owned a number of the Shares equal to the exchange rate on the ex-dividend
date for the cash dividend or distribution.

(5) If the guarantor or any of its subsidiaries makes a payment in respect of a tender offer (which for the avoidance of
doubt  will  not  include  any  open  market  buybacks  or  purchases  that  are  not  tender  offers)  or  exchange  offer  for  the
Shares, to the extent that the cash and value of any other consideration included in the payment per share of

Shares exceeds the average of the last reported sale prices of the Shares over the 10 consecutive trading day period
commencing on, and including, the trading day next succeeding the last date on which tenders or exchanges may be
made pursuant to such tender or exchange offer, the exchange rate will be increased based on the following formula:

ER’ = ER0 x

where,

AC + (SP’ x OS’)
OS0 X SP

ER0

ER’

AC

= the  exchange  rate  in  effect  immediately  prior  to  the  open  of  business  on  the  trading
day  immediately  following  the  trading  day  next  succeeding  the  date  such  tender  or
exchange offer expires;

= the exchange rate in effect immediately after the open of business on the trading day
immediately  following  the  trading  day  next  succeeding  the  date  such  tender  or
exchange offer expires;

= the  aggregate  value  of  all  cash  and  any  other  consideration  (as  determined  by  the
guarantor’s  Board  of  Directors)  paid  or  payable  for  the  Shares  purchased  or
exchanged in the tender or exchange offer;

20

OS0

OS’

SP

SP’

= the  number  of  Shares  outstanding  immediately  prior  to  the  date  such  tender  or
exchange  offer  expires  (prior  to  giving  effect  to  the  purchase  of  all  the  Shares
accepted for purchase or exchange in the tender or exchange offer);

the number of Shares outstanding immediately after the date such tender or exchange
offer  expires  (after  giving  effect  to  the  purchase  of  all  the  Shares  accepted  for
purchase or exchange in the tender or exchange offer);

the  average  of  the  last  reported  sale  prices  of  the  Shares  over  the  10  consecutive
trading  day  period  ending  on,  and  including,  the  trading  day  immediately  preceding
the date the tender or exchange offer expires; and

the  average  of  the  last  reported  sale  prices  of  the  Shares  over  the  10  consecutive
trading day period commencing on, and including, the trading day next succeeding the
date the tender or exchange offer expires.

The  increase  to  the  exchange  rate  under  this  paragraph  (5)  will  occur  at  the  open  of  business  on  the  trading  day
immediately following the trading day next succeeding the date such tender or exchange offer expires; provided that if
the relevant exchange date occurs during the 10 trading days immediately following, and including, the trading day
next  succeeding  the  expiration  date  of  any  tender  or  exchange  offer,  references  to  “10”  or  “10th”  in  the  preceding
paragraph will be deemed replaced with such lesser number of trading days as have elapsed between the date that such
tender or exchange offer expires and the exchange date in determining the exchange rate as of such trading day.

Except  as  stated  above,  the  exchange  rate  will  not  be  adjusted  for  the  issuance  of  the  Shares  or  any  securities
convertible into or exchangeable for the Shares or the right to purchase any of the foregoing.

The guarantor may from time to time, to the extent permitted by law and subject to applicable rules of the New York
Stock Exchange or any exchange on which any of the guarantor’s securities are then listed, increase the exchange rate
of the Exchangeable Bonds by any amount for any period of at least 20 business days. In such case, we will give at
least 15 calendar days’ notice of such increase. We may make such increases in the exchange rate, in addition to those
set forth above, as the guarantor’s board of directors deems advisable or to avoid or diminish any income tax to holders
of our ordinary shares resulting from any dividend or distribution of shares (or rights to acquire shares) or from any
event treated as such for income tax purposes.

Notwithstanding anything in this section to the contrary, we will not be required to adjust the exchange rate unless the
adjustment  would  result  in  a  change  of  at  least  1%  of  the  exchange  rate.  However,  we  will  carry  forward  any
adjustments  that  are  less  than  1%  of  the  exchange  rate  and  take  them  into  account  when  determining  subsequent
adjustments.

In addition, without limiting the generality of any other provision of the Exchangeable Bonds, the exchange rate will
not be adjusted:

(1) upon the issuance of any Shares pursuant to any present or future plan providing for the reinvestment of dividends
or interest payable on the guarantor’s securities and the investment of additional optional amounts in the Shares under
any plan;

(2)  upon  the  issuance  of  any  Shares  or  options  or  rights  to  purchase  the  Shares  pursuant  to  any  present  or  future
employee, director, officer or consultant benefit, compensation or stock purchase plan or program of or assumed by the
guarantor or any of its subsidiaries;

(3) upon the issuance of any Shares pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described above and outstanding as of the issue date of the Exchangeable Bonds;

(4)  upon  the  repurchase  of  any  Shares  pursuant  to  an  open-market  share  repurchase  program  or  other  buyback
transaction that is not a tender or exchange offer of the type described in paragraph (5) above;

(5) solely for a change in the nominal value of the Shares; or

21

(6) for accrued and unpaid interest, if any.

As a result of any adjustment of the exchange rate, the holders of Exchangeable Bonds may, in certain circumstances,
be deemed to have received a distribution that is treated as a dividend for U.S. federal income tax purposes. In certain
other circumstances, the absence of an adjustment may result in a taxable dividend to the holders of ordinary shares.

Recapitalizations, Reclassifications and Changes of the Shares

If the guarantor is a party to (1) a recapitalization, reclassification or change of the Shares, (2) a consolidation, merger
or  combination,  (3)  a  sale,  lease  or  transfer  to  a  third  party  of  the  consolidated  assets  of  the  guarantor  and  its
subsidiaries or (4) any statutory share exchange, in each case, as a result of which the Shares would be converted into,
or exchanged for, stock, other securities, other property or assets, then the exchange rights will be changed into a right
to exchange the Exchangeable Bonds into the kind and amount of stock, other securities, other property or assets that a
holder would have been entitled to receive if such holder had held a number of ordinary shares equal to the applicable
exchange rate in effect immediately prior to the transaction (the “reference property”). The amount of cash and any
reference property holders receive will be based on the daily exchange values of reference property and the applicable
exchange rate, as described above.

If an event described in the immediately preceding paragraph causes the Shares to be converted into, or exchanged for,
the right to receive more than a single type of consideration (determined based in part upon any form of shareholder
election), then (i) the reference property into which the Exchangeable Bonds will be exchangeable will be deemed to
be  (x)  the  weighted  average  of  the  types  and  amounts  of  consideration  received  by  the  holders  of  the  Shares  that
affirmatively make such an election or (y) if no holders of the Shares affirmatively make such an election, the types
and  amounts  of  consideration  actually  received  by  the  holders  of  Shares,  and  (ii)  the  unit  of  reference  property  for
purposes  of  the  immediately  preceding  paragraph  will  refer  to  the  consideration  referred  to  in  clause  (i)  in  this
paragraph attributable to one Share.

To  the  extent  that  the  Exchangeable  Bonds  become  exchangeable  into  the  right  to  receive  cash  following  an  event
described above, interest will not accrue on such cash.

If  the  transaction  also  constitutes  a  fundamental  change,  a  holder  can  alternatively  require  us  to  purchase  all  or  a
portion  of  such  holder’s  Exchangeable  Bonds  as  described  under  “—Repurchase  Rights  Following  Fundamental
Change or Tax Event” below.

Calculations in Respect of the Exchangeable Bonds

We  will  be  responsible  for  making  all  calculations  called  for  under  the  Exchangeable  Bonds.  These  calculations
include, but are not limited to, determinations of the last reported sale prices of the Shares, the accrued interest payable
on the Exchangeable Bonds, the tax event repurchase price, the change of control repurchase price, the listing failure
event repurchase price and the exchange rate of the Exchangeable Bonds. We will make all these calculations in good
faith and, absent manifest error, our calculations shall be final and binding on holders of the Exchangeable Bonds. We
will provide a schedule of our calculations to each of the trustee and the exchange agent, and each of the trustee and
exchange agent is entitled to rely conclusively on the accuracy of our calculations without independent verification.
The trustee will forward our calculations to any holder of the Exchangeable Bonds upon the request of such holder at
our cost and expense.

Repurchase Rights Following Fundamental Change or Tax Event

If we undergo a fundamental change or tax event after the first issuance of the Exchangeable Bonds, each holder will
have the option to require us to purchase its Exchangeable Bonds on a date of our choosing (the “repurchase date”)
that is not less than 60 business days after the fundamental change (or a longer period if required by applicable law). In
the event of a change of control repurchase event, we will pay a purchase price equal to 101% of the principal amount
of  the  holder’s  Exchangeable  Bonds  plus  accrued  and  unpaid  interest  up  to  but  excluding  the  date  of  purchase  (the
“change of control repurchase price”).  In  the  event  of  a  listing  failure  event  or  tax  event,  we  will  pay  a  purchase
price equal to 100% of the principal amount of the holder’s Exchangeable Bonds plus accrued and unpaid interest up

22

to but excluding the date of purchase (the “listing failure event repurchase price” or “tax event repurchase price,”
as  applicable).  However,  if  the  repurchase  date  is  after  a  record  date  and  on  or  prior  to  the  corresponding  interest
payment date, the interest will be paid on the interest payment date to the holder of record on the record date. A holder
may require us to purchase all or any part of the Exchangeable Bonds so long as the principal amount at maturity of
the Exchangeable Bonds being purchased is an integral multiple of $1,000.

Our ability to repurchase Exchangeable Bonds with cash at any time may be limited by the terms of our then existing
borrowing  agreements.  The  indenture  prohibits  us  from  repurchasing  Exchangeable  Bonds  in  connection  with  the
holders’  repurchase  rights  if  any  event  of  default  under  the  indenture  has  occurred  and  is  continuing,  except  for  a
default in the payment of the repurchase price with respect to the Exchangeable Bonds. If a fundamental change occurs
at a time when we are prohibited from repurchasing the Exchangeable Bonds, we could seek the consent of our lenders
to purchase the Exchangeable Bonds or attempt to refinance the debt. If we do not obtain such consent or we are not
able to refinance the debt, we would not be permitted to repurchase the Exchangeable Bonds. Our existing borrowing
agreements currently do not restrict us from repurchasing the Exchangeable Bonds so long as we remain in compliance
with certain financial covenants.

On or before the 20th calendar day after a fundamental change, we will provide notice to the trustee and to each holder
of the Exchangeable Bonds of the fundamental change which specifies the terms and conditions and the procedures
required for exercise of a holder’s right to require us to repurchase its Exchangeable Bonds. Such notice will specify:

(1) the events causing the fundamental change;

(2) the date of such fundamental change;

(3) the last date by which a holder of Exchangeable Bonds may exercise the repurchase right;

(4) the fundamental change repurchase date;

(5) the change of control repurchase price or the listing failure event repurchase price, as applicable;

(6) the name and address of the paying agent and the exchange agent, if applicable;

(7) the exchange rate and any adjustments to the exchange rate;

(8) that Exchangeable Bonds with respect to which a fundamental change purchase notice is given by the holder may
be exchanged only if the fundamental change purchase notice has been withdrawn in accordance with the terms of the
indenture; and

(9) the procedures that holders must follow to exercise these rights.

No  less  than  20  and  no  more  than  60  days  prior  to  the  earliest  date  on  which  we  would  have  to  withhold  tax  in
connection with a tax event, we will provide notice to the trustee and to each holder of the Exchangeable Bonds of the
tax  event  which  specifies  the  terms  and  conditions  and  the  procedures  required  for  exercise  of  a  holder’s  right  to
require us to repurchase its Exchangeable Bonds. Such notice will specify:

(1) the events causing the tax event;

(2) the date of such tax event;

(3) the last date by which a holder of Exchangeable Bonds may exercise the repurchase right;

(4) the tax event repurchase date;

(5) the tax event repurchase price;

23

(6) the name and address of the paying agent and the exchange agent, if applicable;

(7) the exchange rate and any adjustments to the exchange rate;

(8)  that  Exchangeable  Bonds  with  respect  to  which  a  tax  event  purchase  notice  is  given  by  the  holder  may  be
exchanged only if the tax event purchase notice has been withdrawn in accordance with the terms of the indenture;

(9) the impact of such tax event on our obligation to pay additional amounts; and

(10) the procedures that holders must follow to exercise these rights.

To  exercise  the  repurchase  right,  a  holder  of  Exchangeable  Bonds  must  deliver,  at  any  time  prior  to  the  close  of
business on the business day immediately preceding the repurchase date specified in our notice, written notice to the
paying agent of the holder’s exercise of its repurchase right.

The  holder  may  withdraw  any  written  repurchase  notice  by  delivering  a  written  notice  of  withdrawal  to  the  paying
agent  prior  to  the  close  of  business  on  the  business  day  immediately  preceding  the  repurchase  date  that  states  the
principal amount of the withdrawn Exchangeable Bonds, the certificate number of the Exchangeable Bonds in the case
of  a  physical  bond  and  the  principal  amount,  if  any,  of  Exchangeable  Bonds  that  remain  subject  to  the  original
repurchase notice, which must be in principal amounts of $1,000 or an integral multiple of $1,000.

For purposes of defining a fundamental change:

●

●

●

● the  terms  “person”  and  “group”  have  the  meanings  given  to  them  in

Sections 13(d) and 14(d) of the Exchange Act or any successor provisions;

● the  term  “group”  includes  any  group  acting  for  the  purpose  of  acquiring,
holding  or  disposing  of  securities  within  the  meaning  of  Rule  13d-5(b)(1)
under the Exchange Act or any successor provision; and

● the  term  “beneficial  owner”  is  determined  in  accordance  with  Rule  13d-3

under the Exchange Act.

Rule 13e-4 under the Exchange Act, as amended, requires the dissemination of certain information to security holders
if  an  issuer  tender  offer  occurs  and  may  apply  if  the  repurchase  option  becomes  available  to  holders  of  the
Exchangeable Bonds. We will comply with this rule to the extent applicable at that time.

We could, in the future, enter into certain transactions, including certain recapitalizations, that would not constitute a
fundamental change with respect to the fundamental change repurchase feature of the Exchangeable Bonds, but that
would increase the amount of our outstanding indebtedness or the outstanding indebtedness of our subsidiaries.

No  Exchangeable  Bonds  may  be  repurchased  at  the  option  of  holders  upon  a  fundamental  change  if  the  principal
amount of the Exchangeable Bonds has been accelerated, and such acceleration has not been rescinded, on or prior to
such date (except in the case of an acceleration resulting from our default in the payment of the tax event repurchase
price, the change of control repurchase price or the listing failure event repurchase price).

The  fundamental  change  repurchase  feature  of  the  Exchangeable  Bonds  may  in  certain  circumstances  make  it  more
difficult or discourage a takeover of us or the guarantor. The fundamental change repurchase feature, however, is not
the  result  of  our  knowledge  of  any  specific  effort  to  accumulate  the  Shares,  to  obtain  control  of  us  by  means  of  a
merger,  scheme  of  arrangement,  tender  offer  solicitation  or  otherwise,  or  by  management  to  adopt  a  series  of  anti-
takeover  provisions.  Instead,  the  fundamental  change  repurchase  feature  is  a  standard  term  contained  in  securities
similar  to  the  Exchangeable  Bonds,  is  limited  to  specified  transactions  and  may  not  include  other  events  that  might
adversely affect our or the guarantor’s financial condition or results of operations.

Consolidation, Merger and Sale of Assets

24

● We  have  agreed,  for  so  long  as  any  Exchangeable  Bonds  remain
outstanding, that we will not consolidate with or merge into any entity, or
transfer  or  dispose  of  all  or  substantially  all  of  our  assets  to  any  entity,
unless, among certain other requirements:

● either (a) we or the guarantor is the continuing entity or (b) the continuing
entity  is  organized  under  the  laws  of  the  United  States,  the  District  of
Columbia,  the  Cayman  Islands,  Bermuda,  the  British  Virgin  Islands,
Cyprus, the Kingdom of the Netherlands, the Grand Duchy of Luxembourg,
England,  Scotland,  Wales,  Ireland,  or  any  other  jurisdiction  that  does  not
adversely affect the rights of any Holder under the indenture in any material
respect;

● immediately after giving effect to such transaction or series of transactions,
no default or event of default will have occurred and be continuing or would
result therefrom; and

● the  successor  (if  not  us  or  the  guarantor)  expressly  assumes  our  or  the
guarantor’s, as applicable, covenants and obligations under the indenture.

●

●

●

●

Additional Covenants

The covenants summarized below will apply to the Exchangeable Bonds.

Ownership of the Company

The guarantor will continue to own (directly or indirectly) 100% of our common equity.

Covenants with Respect to the Shares

The  guarantor  will  keep  available  at  all  times  (a)  conditional  share  capital  to  issue  and/or  (b)  the  Shares  held  in
treasury by the guarantor or any of its subsidiaries to deliver to holders of the Exchangeable Bonds the full number of
Shares  issuable  or  deliverable,  as  applicable,  upon  exchange  of  the  Exchangeable  Bonds,  which  Shares  will  not  be
subject  by  law  to  preemptive  rights  and  in  respect  of  which  no  contractual  preemptive  rights  will  be  granted.  The
guarantor will cause the person in whose name any Shares will be issuable upon exchange to be effectively treated as a
stockholder of record of such Shares for purposes of any dividends or distribution payable on the Shares as of the close
of business on the relevant exchange date.

The guarantor will not alter its share capital or amend its articles of association if and to the extent such alteration or
amendment  would  have  the  effect  of  preventing,  hindering  or  impairing  the  right  of  holders  of  the  Exchangeable
Bonds to exchange their Exchangeable Bonds for the Shares.

The  guarantor  undertakes  to  and  covenants  with  the  trustee  that  in  the  event  of  our  failing  to  comply  with  our
obligations pursuant to the provisions described under “—Exchange Rights—Settlement Upon Exchange” above, the
guarantor will cause us to comply with such obligations.

Required Information

At any time we and the guarantor are not subject to Sections 13 or 15(d) of the Exchange Act, we will, so long as any
of the Exchangeable Bonds or the Shares constitute “restricted securities” within the meaning of Rule 144(a)(3) under
the Securities Act, promptly provide to any holder, beneficial owner or prospective purchaser of such Exchangeable
Bonds or any such Shares, upon written request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act (or any other provision of Rule 144A, as such rule may be amended from time to time), to
facilitate the resale of such Exchangeable Bonds or the Shares pursuant to Rule 144A under the Securities Act, as such
rule may be amended from time to time.

We and the guarantor will file with the trustee within fifteen days after the same are required to be filed with the SEC,
copies of any documents or reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the

25

Exchange  Act  (giving  effect  to  any  grace  period  provided  by  Rule  12b-25  under  the  Exchange  Act).  Any  such
document or report that we or the guarantor files with the SEC via the SEC’s EDGAR system will be deemed to be
filed with the trustee for purposes of this paragraph at the time such documents are filed via the EDGAR system.

Delivery of such reports, documents and information to the trustee is for informational purposes only, and the trustee’s
receipt  of  such  shall  not  constitute  constructive  notice  of  any  information  contained  therein  or  determinable  from
information contained therein, including our compliance with any of our covenants (as to which the trustee is entitled
to rely exclusively on officers’ certificates). The trustee shall not be obligated to monitor or confirm, on a continuing
basis or otherwise, our compliance with this required information covenant or the posting of any reports, documents
and information on the EDGAR system or any website.

Events of Default

Each of the following will constitute an event of default under the indenture:

● we or the guarantor defaults in the payment of interest on any Exchangeable Bond when

due and payable, and the default continues for a period of 30 days;

● we  or  the  guarantor  defaults  in  the  payment  of  the  principal  (including  the  tax  event
repurchase  price,  change  of  control  repurchase  price  or  listing  failure  event  repurchase
price, if applicable) of, or premium on, any Exchangeable Bond when due and payable at
maturity, upon required repurchase or otherwise;

●

●

●

●

●

●

● we  or  the  guarantor  fails  to  comply  with  our  respective  obligations  to
exchange  the  Exchangeable  Bonds  in  accordance  with  the  indenture  upon
exercise of a holder’s exchange right;

● we or the guarantor fails to make an offer in connection with a fundamental

change or tax event in accordance with the indenture;

● we or the guarantor fails to comply with any covenant or agreement in the
indenture  and  such  default  or  breach  continues  for  90  days  after  we  have
been given written notice specifying such default or breach and requiring it
to be remedied in accordance with the indenture;

● the occurrence of a listing failure event;

● certain  events  involving  bankruptcy,  insolvency  or  liquidation  of  us  or  the

guarantor; and

● the  guarantee  ceases  to  be  in  full  force  and  effect  or  is  declared  null  and
void  in  a  judicial  proceeding,  or  the  guarantor  denies  or  disaffirms  its
obligations under the indenture.

If  an  event  of  default  described  above  will  occur  and  be  continuing,  the  trustee  or  the  holders  of  at  least  25%  in
aggregate principal amount of the Exchangeable Bonds then outstanding may declare the Exchangeable Bonds due and
payable  at  their  principal  amount  together  with  accrued  interest,  and  thereupon  the  trustee  may,  at  its  discretion,
proceed to protect and enforce the rights of the holders of Exchangeable Bonds by appropriate judicial proceedings.
Such  declaration  may  be  rescinded  and  annulled  with  the  written  consent  of  the  holders  of  a  majority  in  aggregate
principal amount of the Exchangeable Bonds then outstanding on behalf of all holders of Exchangeable Bonds, subject
to  the  provisions  of  the  indenture.  Notwithstanding  the  foregoing,  no  such  waiver  or  rescission  and  annulment  will
extend to affect any default or event of default resulting from (i) the nonpayment of the principal (including the change
of control repurchase price, the listing failure event repurchase price or the tax event repurchase price, if applicable) of,
or accrued and unpaid interest on, any Exchangeable Bonds, (ii) failure to repurchase any Exchangeable Bonds when
required  or  (iii)  a  failure  to  pay  or  deliver,  as  the  case  may  be,  the  consideration  due  upon  exchange  of  the
Exchangeable  Bonds.  Further,  notwithstanding  the  foregoing,  the  guarantor’s  failure  to  own  (directly  or  indirectly)
100% of the common equity of us shall constitute an event of default immediately upon such event.

Tax Additional Amounts

We and the guarantor, or any such successor, as applicable, will pay any amounts due with respect to the Exchangeable
Bonds  without  deduction  or  withholding  for  any  and  all  present  and  future  withholding  taxes,  levies,  imposts  and
charges  (a  “withholding  tax”)  imposed  by  or  for  the  account  of  the  Cayman  Islands,  Switzerland  or  any  other
jurisdiction  in  which  we  or  the  guarantor,  or  any  such  successor,  as  applicable,  are  resident  for  tax  purposes  or  any
political  subdivision  or  taxing  authority  of  such  jurisdiction  (the  “taxing jurisdiction”),  unless  such  withholding  or
deduction is required by law. If such deduction or withholding is at any time required, we or the guarantor, or any such
successor, as applicable, will (subject to compliance by you with any relevant administrative requirements) pay you
additional amounts as will result in your receipt of such amounts as you would have received had no such withholding
or deduction been required.

If  the  taxing  jurisdiction  requires  us  to  deduct  or  withhold  any  of  these  taxes,  levies,  imposts  or  charges,  we  or  the
guarantor, or any such successor, as applicable, will (subject to compliance by the holder of Exchangeable Bonds with
any  relevant  administrative  requirements)  pay  these  additional  amounts  in  respect  of  principal  amount,  redemption
price,  repurchase  price  and  interest  (if  any),  in  accordance  with  the  terms  of  the  Exchangeable  Bonds  and  the
indenture,  as  may  be  necessary  so  that  the  net  amounts  paid  to  the  holder  or  the  trustee  after  such  deduction  or
withholding  will  equal  the  principal  amount,  redemption  price,  repurchase  price  and  interest  (if  any),  on  the
Exchangeable Bonds. However, none of us or the guarantor, or any such successor, as applicable, will pay additional
amounts in the following instances:

(1)  if  any  withholding  would  not  be  payable  or  due  but  for  the  fact  that  (1)  the  holder  (or  a  fiduciary,  settlor,
beneficiary of, member or shareholder of, the holder, if the holder is an estate, trust, partnership or corporation), is a
domiciliary,  national  or  resident  of,  or  engaging  in  business  or  maintaining  a  permanent  establishment  or  being
physically present in, the taxing jurisdiction or otherwise having some present or former connection with the taxing
jurisdiction  other  than  the  holding  or  ownership  of  the  Exchangeable  Bonds  or  the  collection  of  principal  amount,
redemption price, repurchase price and interest (if any), in accordance with the terms of the Exchangeable Bonds and
the indenture, or the enforcement of the Exchangeable Bonds or (2) where presentation is required, the Exchangeable
Bonds were presented more than 30 days after the date such payment became due or was provided for, whichever is
later,

(2) if any withholding tax would not have been imposed but for the failure to comply with certification, information,
documentation or other reporting requirements concerning the nationality, residence, identity or connections with the
relevant tax authority of the holder or beneficial owner of the Exchangeable Bonds, if this compliance is required by
statute or by regulation as a precondition to relief or exemption from such withholding tax,

(3) if any withholding tax would not be payable but for a tax event and we have made a tax event offer to repurchase
pursuant to the indenture, or

(4) if any withholding tax is required to be made in respect of payments made to holders of the Exchangeable Bonds
resident  in  Switzerland  (including  any  holders  of  Exchangeable  Bonds  who  fail  to  provide  required  certification,
documentation  or  other  information  establishing  residence  outside  of  Switzerland)  pursuant  to  laws  enacted  by
Switzerland  providing  for  the  taxation  of  payments  according  to  principles  similar  to  those  laid  down  in  the  draft
legislation of the Swiss Federal Council of December 17, 2014, or otherwise changing the Swiss federal withholding
tax  system  from  an  issuer-based  system  to  a  paying  agent-based  system  to  which  a  person  other  than  the  issuer  is
required to withhold tax on any interest payment, or any combination of the instances described in the preceding bullet
points.

Notwithstanding  anything  herein  to  the  contrary,  if  a  holder  does  not  elect  to  exchange,  or  cause  repurchase  of,  its
Exchangeable Bonds following a tax event, none of us or the guarantor, or any such successor, as applicable, will be
required to pay additional amounts with respect to payments made in respect of such Exchangeable Bonds following
the tax event repurchase date, and all subsequent payments in respect of such Exchangeable Bonds will be subject to
any  tax  required  to  be  withheld  or  deducted  under  the  laws  of  a  relevant  taxing  jurisdiction.  The  obligation  to  pay
additional amounts to any such holder for payments made on or in periods prior to the tax event repurchase date will
remain subject to the exceptions described above.

Satisfaction and Discharge

27

When (a)(i) all outstanding Exchangeable Bonds have been delivered to the trustee for cancellation; or (ii) we or the
guarantor  has  deposited  with  the  trustee  or  delivered  to  holders,  as  applicable,  after  the  Exchangeable  Bonds  have
become  due  and  payable,  whether  on  the  maturity  date,  any  tax  event  repurchase  date,  any  fundamental  change
repurchase  date,  upon  exchange  or  otherwise,  cash,  the  Shares,  and  any  cash  in  lieu  of  fractional  Shares,  solely  to
satisfy the guarantor’s exchange obligation, sufficient, without consideration of any reinvestment of interest, to pay all
of  the  outstanding  Exchangeable  Bonds  and  all  other  sums  due  and  payable  under  the  indenture  by  us  and  the
guarantor; and (b) we have delivered to the trustee an officers’ certificate and an opinion of counsel, each stating that
all conditions precedent for the satisfaction and discharge of the indenture have been complied with, then the indenture
will cease to be of further effect with respect to the Exchangeable Bonds.

Amendments to the Indenture

With the consent of the holders of at least a majority of the aggregate principal amount of the Exchangeable Bonds
then  outstanding,  we,  the  guarantor  and  the  trustee  may  enter  into  supplemental  indentures  for  the  purpose  of
modifying or amending any of the provisions of the indenture or any supplemental indentures thereto, or of modifying
in any manner the rights of the holders hereunder or thereunder; provided, however, that, without the consent of each
holder of an outstanding Exchangeable Bond affected, no such supplemental indenture shall:

●

●

●

● reduce  the  principal  amount  of  the  then  outstanding  Exchangeable  Bonds  whose

holders must consent to an amendment, supplement or waiver;

● reduce the principal of or change the fixed maturity of any Exchangeable Bonds;

● reduce the rate of or change the time for payment of interest on any Exchangeable

Bond;

● make  any  change  that  adversely  affects  the  exchange  rights  or  tax  event  or  fundamental

change repurchase rights of the Exchangeable Bonds;

● waive a default or event of default in the payment or delivery, as the case may be, of (i) the
principal (including the tax event repurchase price, the change of control repurchase price or
the listing event repurchase price, if any) of, (ii) interest on or (iii) any consideration due upon
exchange  of,  the  Exchangeable  Bonds  (except  a  rescission  of  acceleration  of  the
Exchangeable Bonds by the holders of at least a majority in aggregate principal amount of the
then outstanding Exchangeable Bonds and a waiver of the payment default that resulted from
such acceleration);

●

●

●

●

●

●

● make  any  Exchangeable  Bond  payable  in  money  other  than  that  stated  in  the

Exchangeable Bond;

● make  any  change  in  the  provisions  of  the  indenture  relating  to  waivers  of  past
defaults  or  the  rights  of  holders  of  Exchangeable  Bonds  to  receive  payments  of
principal of, or interest or premium, if any, on the Exchangeable Bonds;

● adversely  alter  any  of  the  provisions  with  respect  to  a  repurchase  of  the
Exchangeable  Bonds  upon  a  tax  event  or  fundamental  change  or  waive  any
payment of the tax event repurchase price, the change of control repurchase price
or the listing failure event repurchase price;

● cause the Exchangeable Bonds or the guarantee to become subordinated in right of

payment to any other indebtedness of us or the guarantor, as applicable;

● make any change in the amendment and waiver provisions; or

● release  the  guarantor  from  its  obligations  under  the  guarantee  or  the  indenture,

except as permitted by the indenture.

28

Further, without requiring the consent of any holders, we, the guarantor and the trustee may enter into supplemental
indentures for one or more of the following purposes:

● to cure any ambiguity or to correct or supplement any provision in the indenture
which may be inconsistent with any other provision in the indenture, provided
such action will not adversely affect the interests of the holders of Exchangeable
Bonds in any material respect;

● to  provide  for  uncertificated  Exchangeable  Bonds  in  addition  to  or  in  place  of
physical bonds or to alter the provisions of the indenture regarding the form of
the  Exchangeable  Bonds  (including  the  related  definitions)  in  a  manner  that
does  not  adversely  affect  any  holder  of  Exchangeable  Bonds  in  any  material
respect;

● to provide for the assumption of our or the guarantor’s obligations to the holders
under the indenture by a successor company as provided for in the indenture;

● to make any change that would provide any additional rights or benefits to the
holders that does not adversely affect the legal rights hereunder of any holder in
any  material  respect,  as  determined  in  good  faith  by  us,  as  evidenced  in  an
officers’ certificate, or to surrender any right or power conferred upon us or the
guarantor;

● to evidence and provide the acceptance of the appointment of a successor trustee

pursuant to the terms of the indenture;

● to add an additional guarantor to the Exchangeable Bonds;

● to increase the exchange rate;

the indenture;

● in  connection  with  any  event  described  under  “—Recapitalizations,
Reclassifications and Changes of the Shares,” to provide that the Exchangeable
Bonds are exchangeable into reference property, subject to the provisions of the
indenture,  and  make  such  related  changes  to  the  terms  of  the  Exchangeable
Bonds to the extent expressly required; or

● to  conform  the  provisions  of  the  indenture  of  the  Exchangeable  Bonds  to  this

Global Exchangeable Bonds: Book-Entry Form

The  Exchangeable  Bonds  are  represented  by  one  or  more  global  securities.  A  global  security  is  a  special  type  of
indirectly held security. Each global security is deposited with, or on behalf of, DTC and be registered in the name of a
nominee of DTC.

Investors may hold interests in the Exchangeable Bonds outside the United States through Euroclear or Clearstream if
they  are  participants  in  those  systems,  or  indirectly  through  organizations  which  are  participants  in  those  systems.
Euroclear and Clearstream will hold interests on behalf of their participants through customers’ securities accounts in
Euroclear’s  and  Clearstream’s  names  on  the  books  of  their  respective  depositaries  which  in  turn  will  hold  such
positions in customers’ securities accounts in the names of the nominees of the depositaries on the books of DTC. All
securities in Euroclear or Clearstream are held on a fungible basis without attribution of specific certificates to specific
securities clearance accounts.

Ownership  of  beneficial  interests  in  a  global  security  will  be  limited  to  DTC  participants  (i.e.,  persons  that  have
accounts with DTC or its nominee) or persons that may hold interests through DTC participants including Euroclear
and Clearstream. Ownership of beneficial interests in a global security will be shown on, and the transfer of that

29

ownership will be effected only through, records maintained by DTC or its nominee (except with respect to persons
that are themselves DTC participants).

So long as DTC or its nominee is the registered owner of a global security, DTC or the nominee will be considered the
sole  owner  or  holder  of  the  Exchangeable  Bonds  represented  by  that  global  security  under  the  indenture.  Except  as
described below, owners of beneficial interests in a global security will not be entitled to have Exchangeable Bonds
represented by that global security registered in their names, will not receive or be entitled to receive physical delivery
of Exchangeable Bonds in definitive form and will not be considered the owners or holders of the Exchangeable Bonds
under  the  indenture.  Principal  and  interest  payments  on  Exchangeable  Bonds  registered  in  the  name  of  DTC  or  its
nominee  will  be  made  to  DTC  or  the  nominee,  as  the  registered  owner.  None  of  us,  the  guarantor,  the  trustee,  any
paying agent or the registrar for the Exchangeable Bonds will have any responsibility or liability for any aspect of the
records  relating  to  or  payments  made  on  account  of  beneficial  interests  in  a  global  security  or  for  maintaining,
supervising or reviewing any records relating to such beneficial interests or with respect to delivery to any participant,
member, beneficial owner or other person (other than DTC) of any notice. The laws of some states require that certain
purchasers of securities take physical delivery of such securities in definitive form. Those limits and laws may impair
the ability to transfer beneficial interests in a global security.

We expect that DTC or its nominee, upon receipt of any payment of principal or interest, will credit immediately the
participants’ accounts with payments in amounts proportionate to their beneficial interests in the principal amount of
the  relevant  global  security  as  shown  on  the  records  of  DTC  or  its  nominee.  We  also  expect  that  payments  by
participants to owners of beneficial interests in a global security held through those participants will be governed by
standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer
form or registered in “street name,” and will be the responsibility of those participants.

If DTC is at any time unwilling or unable to continue as a depositary and a successor depositary is not appointed by us
within 90 days, we will issue Exchangeable Bonds in definitive form in exchange for the entire global security for the
Exchangeable Bonds. In addition, we may at any time choose not to have Exchangeable Bonds represented by a global
security and will then issue Exchangeable Bonds in definitive form in exchange for the entire global security relating
to the Exchangeable Bonds. In any such instance, an owner of a beneficial interest in a global security will be entitled
to  physical  delivery  in  definitive  form  of  Exchangeable  Bonds  represented  by  the  global  security  equal  in  principal
amount to that beneficial interest and to have the Exchangeable Bonds registered in its name. Exchangeable Bonds so
issued in definitive form will be issued as registered Exchangeable Bonds in minimum denominations of $1,000 and
integral multiples thereof, unless otherwise specified by us.

Meetings of Holders

Meetings of holders of Exchangeable Bonds may be called at any time for any of the following purposes:

● to give any notice to us or to the trustee or to give any directions to the trustee
permitted  under  the  indenture,  or  to  consent  to  the  waiving  of  any  default  or
event of default under the indenture and its consequences, or to take any other
action authorized to be taken by holders of Exchangeable Bonds in respect of
an event of default or remedy in respect of an event of default;

● to  remove  the  trustee  and  nominate  a  successor  trustee  pursuant  to  the

indenture;

● to  consent  to  the  execution  of  an  indenture  or  supplemental  indenture

amending or modifying the indenture; or

● to take any other action authorized to be taken by or on behalf of the holders of
any  specified  aggregate  principal  amount  of  Exchangeable  Bonds  under  any
other provision of the indenture.

Calls of Meetings

30

The trustee may at any time call a meeting of holders of Exchangeable Bonds to take any action specified above, to be
held at such time and place as the trustee will determine. Notice of every meeting of holders of Exchangeable Bonds,
setting forth the time and place of such meeting and in general terms the action proposed to be taken at such meeting
and the establishment of any record date, will be delivered to holders of Exchangeable Bonds. Such notice will also be
delivered to us, not less than 20 or more than 90 days prior to the date fixed for the meeting.

Any meeting of holders of Exchangeable Bonds will be valid without notice if the holders of all Exchangeable Bonds
then outstanding are present in person or by proxy or if notice is waived before or after the meeting by the holders of
all  Exchangeable  Bonds  then  outstanding,  and  if  we  and  the  trustee  are  either  present  by  duly  authorized
representatives or have, before or after the meeting, waived notice.

In case at any time we or the holders of at least 25% of the aggregate principal amount of the Exchangeable Bonds
then outstanding will have requested the trustee to call a meeting of holders of Exchangeable Bonds, by written request
setting forth in reasonable detail the action proposed to be taken at the meeting, and the trustee will not have delivered
the notice of such meeting within 20 days after receipt of such request, then we or such holders may determine the
time and the place for such meeting and may call such meeting to take any action described above, by delivering notice
thereof as provided in this section.

Qualifications for Voting

To be entitled to vote at any meeting of holders, a person must (a) be a holder of one or more Exchangeable Bonds on
the record date pertaining to such meeting and (b) be a person appointed by an instrument in writing as proxy by a
holder of one or more Exchangeable Bonds on the record date pertaining to such meeting. The only persons entitled to
be present or to speak at any meeting of holders will be the persons entitled to vote at such meeting and their counsel,
any representatives of the trustee and its counsel and any of our representatives and our counsel.

Notices

Any  notice  or  communication  delivered  or  to  be  delivered  to  a  holder  of  Exchangeable  Bonds,  so  long  as  the
Exchangeable  Bonds  remain  in  global  form,  will  be  delivered  in  accordance  with  the  applicable  procedures  of  the
depositary  and  shall  be  sufficiently  given  to  it  if  so  delivered  within  the  time  prescribed.  Notices  to  holders  of
Exchangeable  Bonds  in  certificated  form  will  be  given  by  mail  to  the  holder’s  address  as  it  appears  in  the
Exchangeable Bonds register.

Information Regarding the Co-Trustees

Computershare  Trust  Company,  N.A.  and  Computershare  Trust  Company  of  Canada  are  co-trustees  under  the
indenture governing the Exchangeable Bonds. Computershare Trust Company, N.A. has also been appointed by us as
paying  agent,  exchange  agent,  registrar  and  custodian  with  regard  to  the  Exchangeable  Bonds.  The  trustee  and  its
affiliates  provide  and  may  from  time  to  time  in  the  future  provide  banking  and  other  services  to  us  in  the  ordinary
course of their business.

PERFORMANCE UNITS

1.

Determination of Earned Performance Units

(a)

Total Target Performance Unit Grant

For  purposes  of  the  Award  Letter  (including  this  Appendix  A),  the  term
“Total  Target  Performance  Units”  shall  mean  the  total  number  of  target
Shares (or other consideration) that may be issued to you in respect of
the achievement of certain performance standards as described herein,
subject to the terms and conditions hereof.

(b)

Earned Performance Units

The exact number of Performance Units that will actually be earned by
and issued to you and subject to the vesting described in Section I.2 (the
“Earned Performance Units”) will be based upon the achievement by the
Company  of  the  performance  standard,  as  described  in  this  Section
I.1(b).    The  performance  standard  shall  be  measured  for  (1)  the  three
calendar year periods ending December 31, 2023, December 31, 2024
and  December  31,  2025  (each  a  “Calendar  Performance  Period”),  and
(2)  the  cumulative  period  beginning  January  1,  2023  and  ending
December 31, 2025 (the “Cumulative Performance Period”).  

After the conclusion of each of the Calendar Performance Periods, and
at the conclusion of the Cumulative Performance Period, the Committee
will  make  a  determination  as  to  the  number  of  Earned  Performance
Units based on the Company’s relative performance on total shareholder
return (“TSR”) as

Appendix A

to  any  adjustment 

compared  against  a  peer  group  (as  identified  in  Exhibit  A)  over  the
respective  Calendar  Performance  Period  and 
the  Cumulative
Performance  Period,  and  at  the  conclusion  of  each  Calendar  and
the  Committee  will  make  a
Cumulative  Performance  Period 
determination  as 
the  number  of  Earned
Performance  Units  based  on  the  Company’s  absolute  performance  on
TSR.    The  determination  by  the  Committee  with  respect  to  the
achievement of absolute and relative TSR will be made in the first sixty
days  following  the  end  of  the  respective  Calendar  and  Cumulative
Performance  Period  after  all  necessary  Company  and  peer  information
is available.  The specific date on which such determination is formally

More  detailed  definitions  for  TSR  and  the  methodology  for  determining
the Earned Performance Units are incorporated herein as Exhibit A.

(c)

Committee Determinations

The Committee shall have absolute discretion to determine the number
of Earned Performance Units to which you are entitled, if any, including
without limitation such adjustments as may be necessary in the opinion
of  the  Committee  to  account  for  changes  since  the  date  of  the  Award
Letter.    The  Committee’s  determination  shall  be  final,  conclusive  and
binding upon you.  You shall not have any right or claim with respect to
any  units  other  than  Earned  Performance  Units  to  which  you  become
entitled in accordance with this Appendix A.

2.

Vesting

(b)

Unless  vested  on  an  earlier  date  as  provided  in  this  Appendix  A,  the
Earned  Performance  Units  will  be  vested  on  December  31,  2025,
subject to your continued employment through that date.

In certain circumstances more particularly described in Sections I.5 and
I.6 below, your Earned Performance Units may vest before the date set
forth  in  Section  I.2(a).    In  addition,  the  Committee  may  accelerate  the

Restrictions

Until  and  unless  you  vest  in  your  Earned  Performance  Units  and  receive  a
distribution of Shares, you do not own any of the Shares potentially subject to
this performance award and may not attempt to sell, transfer, assign or pledge
any such Shares.  After the Cumulative Performance Period has ended and all
Earned  Performance  Units  are  determined,  the  net  Shares  (total  Shares
distributable in respect of vested Earned Performance Units minus any Shares
retained  by  the  Company  in  accordance  with  the  policies  and  requirements
described in Section IV.4) will be delivered on March 15,

a  brokerage  account  in  the  name  of  your  beneficiary  under  the  Plan)  with  the
broker  retained  by  the  Company  for  such  purpose  (the  “Broker”).   Any  Shares
distributed  to  you  in  respect  of  vested  Earned  Performance  Units  will  be
registered 
to  any  restrictions.
 Notwithstanding the foregoing, the number of Shares distributed to you will be
subject  to  the  number  of  Shares  that  remain  available  for  issuance  under
Paragraph  5  of  the  Plan,  as  amended,  and  the  Committee  may  make  such
adjustment  as  it  deems  appropriate  to  the  number  of  Shares  distributed  to
reflect any limitation on Shares available.

Dividend Equivalents, Dividends and Voting

(a)

(b)

(c)

Vested  Earned  Performance  Units.    In  the  event  that  dividends  are
paid with respect to Shares such that the applicable record date for such
dividends  occurs  during  the  period  beginning  on  the  Grant  Date  and
ending on the date you receive a distribution of Shares in satisfaction of
your vested Earned Performance Units, you will be entitled to receive a
cash payment equal to the amount of the dividend paid per Share as of
each  such  dividend  payment  date  multiplied  by  the  number  of  vested
Earned Performance Units (the “Earned Dividend Equivalent”).  You will
have  no  right  to  receive  any  payment  of  dividend  equivalents  with
respect  to  Performance  Units  that  do  not  become  vested  Earned
Performance Units.  All Earned Dividend Equivalents (if any) will be paid
in cash on the date of the regularly scheduled payroll next following the
date  of  distribution  of  Shares  with  respect  to  your  vested  Earned
Performance  Units,  or  as  soon  as  administratively  practicable  following
such  date  and  shall  be  subject  to  all  applicable  withholding  taxes.    For
any  non-cash  dividends,  the  Committee  may  determine  in  its  sole
discretion the cash value to be so paid to you in respect of such vested
Earned Performance Units or, if applicable, the adjustment to be applied
pursuant to Section 15 of the Plan.

Voting Shares.    You  will  have  the  right  to  vote  your  Shares  that  have
been  distributed  in  respect  of  any  vested  Earned  Performance  Units.
There are no voting rights associated with Performance Units (including
Earned Performance Units).

No Other Rights.  You shall have no other dividend equivalent, dividend
or voting rights with respect to any Performance Unit.

1.

Vesting and Restricted Share Units

(a)

Unless  vested  on  an  earlier  date  as  provided  in  this  Appendix  A,  the
Restricted  Share  Units  granted  pursuant  to  your  Award  Letter  will  fully
vest  in  installments  in  accordance  with  the  following  vesting  schedule
(each  date  below,  an  “RSU  Vesting  Date”)  provided  that  you  remain
continuously employed through the applicable RSU Vesting Date:

1/3
1/3

To the extent that the vesting schedule above would result in vesting of a
fractional  Restricted  Share  Unit,  such  fractional  Restricted  Share  Unit
shall be rounded to a whole number as determined by the Committee.

(b)

In certain circumstances described in Section II.4 below, your Restricted
Share Units may fully vest before the final scheduled RSU Vesting Date.
 In addition, the Committee may accelerate the vesting of all or a portion
of your Restricted Share Units at any time in its discretion, subject to the
provisions of Section II.4(d).  The date of any accelerated vesting under
Section  II.4  below  will  be  a  RSU  Vesting  Date  for  purposes  of  this
Appendix A.

(c)

You  do  not  need  to  pay  any  purchase  price  for  the  Restricted  Share
Units unless otherwise required in accordance with applicable law.

2.

Restrictions on the Restricted Share Units

Until  and  unless  you  vest  in  your  Restricted  Share  Units  and  receive  a
distribution  of  Shares,  you  may  not  attempt  to  sell,  transfer,  assign  or  pledge
them.  Until the date on which you receive a distribution of the Shares in respect
of  any  vested  Restricted  Share  Units  awarded  hereunder,  your  award  of
Restricted Share Units will be evidenced by credit to a book entry account.

When  Restricted  Share  Units  vest  and  become  payable,  the  net  Shares  (total
Shares  distributable  in  respect  of  vested  Restricted  Share  Units  minus  any
Shares  retained  by  the  Company  in  accordance  with  the  policies  and
requirements  described  in  Section  IV.4),  will  be  delivered  to  you  within  sixty
days after the RSU Vesting Date in street name to your brokerage account (or,
in  the  event  of  your  death,  to  a  brokerage  account  in  the  name  of  your
beneficiary  under  the  Plan)  with  the  Broker.   Any  Shares  distributed  to  you  in
respect of vested Restricted Share Units will be registered in your name and will
not be subject to any restrictions.  There will be some delay between the RSU
Vesting  Date  and  the  date  your  Shares  become  available  to  you  due  to
administrative reasons.

Dividend Equivalents and Voting

(a)

Dividend Equivalents

In the event that dividends are paid with respect to Shares such that the
applicable record date occurs during the period beginning on the Grant
Date  and  ending  on  the  date  you  receive  a  distribution  of  Shares  in
satisfaction of your vested Restricted Share Units, you will be entitled to
receive  a  cash  payment  equal  to  the  amount  of  the  dividend  paid  per
Share  as  of  such  dividend  payment  date  multiplied  by  the  number  of
vested  Restricted  Share  Units  (the  “Dividend  Equivalent”).    Dividend
Equivalents (if any) payable with respect to your vested Restricted Share
Units will be paid in cash on the date of the regularly scheduled payroll
next following the applicable Vesting Date, or as soon as administratively
practicable  following  such  date,  and  shall  be  subject  to  all  applicable
withholding  taxes.    For  any  non-cash  dividends,  the  Committee  may
determine  in  its  sole  discretion  the  cash  value  to  be  so  paid  to  you  in
respect  of  such  Restricted  Share  Units  or,  if  applicable,  the  adjustment
to be applied pursuant to Section 15 of the Plan.

(b)

Voting Shares

You will have the right to vote your Shares that have been distributed in
respect of any vested Restricted Share Units.  There are no voting rights
associated with Restricted Share Units.

(c)

No Other Rights

You  shall  have  no  other  dividend  equivalent,  dividend  or  voting  rights
with respect to any Restricted Share Unit.

4.

Termination of Employment

The  following  rules  apply  to  the  vesting  of  your  Restricted  Share  Units  in  the
event of your termination of employment.

(a)

(b)

Death  or  Disability.    If  your  employment  is  terminated  by  reason  of
death  or  Disability,  all  of  your  Restricted  Share  Units  will  vest  on  your
date of termination.  If you are Retirement Eligible and you experience a
Disability  that  satisfies  the  requirements  of  U.S.  Treasury  Regulation
Section 1.409A-3(i)(4) prior to the termination of your employment, all of
your Restricted Share Units will vest on the date of such Disability.

Involuntary  Termination  or  Retirement.    If  your  employment  is
terminated in an Involuntary Termination or by reason of you becoming a
Retiree,  a  pro  rata  portion  of  your  Restricted  Share  Units  will  vest  on
your  date  of  termination;  such  pro  rata  portion  shall  be  determined  by
multiplying  the  number  of  Restricted  Share  Units  granted  to  you  and
remaining  outstanding  and  unvested  at  the  time  your  employment  is
terminated  by  a  fraction,  the  numerator  of  which  is  the  number  of
calendar  days  you  were  employed  between  the  Grant  Date  and  your
date of termination and the denominator

Appendix A

-6-

(c)

(d)

of which is the number of calendar days between the Grant Date and the
final scheduled RSU Vesting Date.

Other Termination of Employment.  If your employment terminates for
any reason other than those set forth in Sections II.4(a), II.4(b) and II.5,
any of your Restricted Share Units which have not vested prior to your
termination of employment will be forfeited.

Adjustments  by  the  Committee.    The  Committee  may,  in  its  sole
discretion, accelerate the vesting of all or any portion of your Restricted
Share  Units;  provided,  however,  that  no  acceleration  of  delivery  of
Shares  shall  be  made  in  a  manner  that  is  not  in  compliance  with,  or
exempt from, any applicable requirements of Code Section 409A.

5.

Change of Control.  

Notwithstanding the provisions of the Award Letter or Sections II.1 or II.4, all of
your  Restricted  Share  Units  will  vest  immediately  upon  a  Change  of  Control
Termination.

Section III.Miscellaneous

The terms and provisions of this Section III apply to all Awards.  

1.

Definitions

(a)

(b)

(c)

“Cause”  means  (1)  your  willful  and  continued  failure  to  substantially
perform  your  duties  with  the  Company  (other  than  any  such  failure
resulting from your incapacity due to physical or mental illness), (2) your
willful  engagement  in  conduct  which  is  demonstrably  and  materially
injurious to the Company or its Subsidiaries, monetarily or otherwise, (3)
your willful, material breach of any written policy of the Company or any
written  agreement  between  you  and  the  Company  or  any  of  its
Subsidiaries,  including,  but  not  limited  to,  the  Company’s  Code  of
Integrity, human resource or legal compliance and ethics policies or any
felony  or  a
employment  agreement,  (4)  your 
misdemeanor involving fraud, dishonesty or moral turpitude, or (5) such
other events, acts or omissions as shall be determined in good faith.  For
purposes of clauses (1), (2) and (3) of this definition, no act, or failure to
act, on your part shall be deemed “willful” unless done, or omitted to be
done,  by  you  not  in  good  faith  and  without  reasonable  belief  that  your
act, or failure to act, was in the best interest of the Company.

indictment  of  a 

“Change  of  Control  Termination”  means  and  occurs  on  the  date  of
your  termination  of  employment  by  the  Company  or  any  Subsidiary  for
any reason other than Cause within two years after the date of a Change
of Control.

“Disability”  means  (1)  you  qualify  for  disability  benefits  under  a  long
term  disability  plan  sponsored  by  the  Company  or  (2)  if  you  are  not
covered  by  any  such  long  term  disability  plan,  the  Chief  Executive
Officer of the Company, or in the case of the termination of employment
of  the  Chief  Executive  Officer  of  the  Company,  the  Committee,  has
determined that you are disabled.

Appendix A

(d)

(e)

(f)

(g)

(h)

“Good  Reason”  means  (1) 
the  diminution  of  your  duties  or
responsibilities,  or  a  demotion  of  your  position,  to  such  an  extent  or  in
such a manner as to relegate you to a position not substantially similar
to that which you held prior to such change or (2) a material reduction in
your  base  salary  or  annual  incentive  plan  opportunities  other  than  in
connection  with  such  reductions  that  are  applicable  to  the  Company’s
executives as a group.  You shall not be considered to have terminated
for  Good  Reason  unless  you  notify  the  Company  in  writing  within  30
days  of  the  date  the  event  giving  rise  to  Good  Reason  occurs,  the
Company  does  not  cure  such  condition  within  30  days  of  such  notice
and you terminate your employment no later than 90 days after the date
the event giving rise to Good Reason occurred.

“Involuntary Termination” means the termination of your employment
(i) by the Company without Cause or (ii) by you for Good Reason.

With  respect  to  an  award  of  Performance  Units,  “Pro-Rata  Earned
Award” is determined by multiplying the number of Earned Performance
Units  which  would  have  otherwise  been  earned  for  each  of  the  three
Calendar Performance Periods and the Cumulative Performance Period
had your employment not been terminated by a fraction, the numerator
of which is the number of calendar days you were employed during the
period  beginning  January  1,  2023  and  ending  December  31,  2025  and
the  denominator  of  which  is  the  total  number  of  calendar  days  in  the
period beginning January 1, 2023 and ending December 31, 2025.

You  are  a  “Retiree”  if  your  separation  from  service  occurs  for  any
reason  other  than  Cause,  Involuntary  Termination,  Change  in  Control
Termination,  death  or  Disability  after  (a)  attainment  of  age  62  and  (b)
completion  of  at  least  five  years  of  service  with  the  Company  or  its
Subsidiaries.

With  respect  to  an  award  of  Restricted  Share  Units,  “Retirement
Eligible”  means,  and  will  apply  if,  your  final  RSU  Vesting  Date  is
scheduled to occur after the calendar year in which you will complete at
least five years of service with the Company or its Subsidiaries and will
attain at least age 62.

2.

Award Determinations

The Chief Executive Officer of the Company, or in the case of the termination of
employment  of  the  Chief  Executive  Officer  of  the  Company,  the  Committee,
shall  have  absolute  discretion  to  determine  the  date  and  circumstances  of
termination  of  your  employment  or  separation  from  service,  including  without
limitation whether as a result of Disability, Involuntary Termination, Cause, Good
Reason  or  any  other  reason  and  whether  you  are  a  Retiree,  and  such
determination shall be final, conclusive and binding upon you.

3.

Section 280G Limitation

Notwithstanding anything in the Award Letter (including this Appendix A) to the
contrary, if all or any portion of the benefits provided hereunder, either alone or
together with other payments and benefits received or to be received from the

Appendix A

-8-

Company or any affiliate or successor, would constitute a “parachute payment”,
as  such  term  is  defined  in  Code  Section  280G(b)(2),  the  aggregate  of  the
amounts  constituting  the  parachute  payment  shall  be  reduced  to  the  extent
necessary so that no portion thereof shall be subject to the excise tax imposed
by Code Section 4999, but only if, by reason of such reduction, the net after-tax
benefit  shall  exceed  the  net  after-tax  benefit  if  such  reduction  were  not  made.
  “Net  after-tax  benefit”  for  these  purposes  shall  mean  the  sum  of  (w)  the  total
amount  payable  under  this  Award,  plus  (x)  all  other  payments  and  benefits
which  you  receive  or  are  then  entitled  to  receive  from  the  Company  or  an
Affiliate  that,  alone  or  in  combination  with  the  amounts  payable  under  the
Award,  would  constitute  a  “parachute  payment”  within  the  meaning  of  Code
Section 280G, less (y) the amount of federal income taxes payable with respect
to the foregoing calculated at the maximum marginal income tax rate for each
year in which the foregoing shall be paid (based upon the rate in effect for such
year as set forth in the Code at the time of the payment under the Plan), less
(z)  the  amount  of  excise  taxes  imposed  with  respect  to  the  payments  and
benefits described in (w) and (x) above by Code Section 4999.  Such reduction
shall be made to those amounts that provide you with the best economic benefit
(and  to  the  extent  any  payments  are  economically  equivalent,  each  shall  be
reduced  pro  rata),  which  may  include,  without  limitation  and  to  the  extent
necessary, a reduction to the Awards or vesting of the Awards in order that this
limitation  not  be  exceeded;  provided,  however,  that  this  Section  IV.3  shall  be
superseded in its entirety by (i) any contrary treatment of parachute payments to
which you have agreed in writing prior to the Change of Control pursuant to any
other  plan,  program  or  agreement,  or  (ii)  any  more  favorable  treatment  of  the
excise  tax  on  parachute  payments  extended  to  you  by  the  Company  or  its
affiliates pursuant to any other plan, program or agreement.

4.

Tax Consequences and Withholding

(a)

(b)

You  should  consult  the  Plan  Prospectus  for  a  general  summary  of  the
Swiss  federal  income  tax  consequences  to  you  and,  if  applicable,  the
U.S. tax consequences to you, upon the grant, vesting or distribution to
you of the Awards based on currently applicable provisions of the Code,
related regulations and Swiss tax rules. The summary does not discuss
state and local tax laws or the laws of any other jurisdictions, which may
differ  from  the  U.S.  federal  tax  law  and  Swiss  tax  rules.  For  these
reasons,  you  are  urged  to  consult  your  own  tax  advisor  regarding  the
application of the tax laws to your particular situation.

With  respect  to  Awards  of  Performance  Units  under  Section  I  and
Restricted  Share  Units  under  Section  II,  the  Company  shall  reduce  the
number  of  Shares  otherwise  deliverable  to  you  with  respect  to  your
Earned  Performance  Units  or  Restricted  Share  Units  by  a  number  of
Shares having a value approximately equal to the amount required to be
withheld  under  the  Company’s  policies  and  procedures  or  applicable
law.  Further, any dividend equivalents paid to you in respect of Earned
Performance Units or Restricted Share Units pursuant to Section I.4 or
II.3,  respectively,  will  be  subject  to  tax  withholding,  as  appropriate,  as
additional compensation.

Appendix A

-9-

(c)

(d)

You  may  not  elect  to  have  the  Broker  withhold  Shares  having  a  value
less  than  the  minimum  statutory  withholding  tax  liability  or,  if  you  are
serving as an expatriate employee, the “standard deduction” withheld in
accordance  with  the  Company’s  policies  and  procedures.  If  you  fail  to
satisfy such withholding obligation in a time and manner satisfactory to
the Company, the Company shall have the right to withhold the required
amount from your salary or other amounts payable to you.

In  addition  to  the  previous  withholding  requirements,  any  award  under
the  Plan  is  also  subject  to  all  applicable  withholding  policies  of  the
Company as may be in effect from time to time, at the sole discretion of
the  Company.    Without  limiting  the  generality  of  the  foregoing,  the
Company  expressly  has  the  right  to  collect  or  cause  to  be  collected,
pursuant  to  any  tax  equalization  or  other  plan  or  policy,  as  any  such
policies  or  plans  may  be  in  effect  from  time  to  time  (irrespective  of
whether  such  withholding  correlates  to  the  applicable  tax  withholding
requirement with respect to your award) proceeds of the sale of Shares
acquired upon vesting of the applicable award through a sale arranged
by the Company or Broker on your behalf pursuant to this authorization
without further consent.  Awards are further subject to any tax and other
reporting requirement that may be applicable in any pertinent jurisdiction
including any obligation to report awards (whether related to the granting
or  vesting  thereof  or  exercise  of  rights  thereunder)  to  any  taxing
authority or other pertinent third party.

5.

Restrictions on Resale

Other  than  the  restrictions  referenced  in  Sections  I.3  and  II.2,  there  are  no
restrictions  imposed  by  the  Plan  on  the  resale  of  Shares  acquired  under  the
Plan.    However,  under  the  provisions  of  the  Securities  Act  and  the  rules  and
regulations  of  the  SEC,  resales  of  Shares  acquired  under  the  Plan  by  certain
officers and directors of the Company who may be deemed to be “affiliates” of
the  Company  must  be  made  pursuant  to  an  appropriate  effective  registration
statement  filed  with  the  SEC,  pursuant  to  the  provisions  of  Rule  144  issued
under  the  Securities  Act,  or  pursuant  to  another  exemption  from  registration
provided in the Securities Act.  At the present time, the Company does not have
a currently effective registration statement pursuant to which such resales may
be  made  by  affiliates.    There  are  no  restrictions  imposed  by  the  SEC  on  the
resale  of  Shares  acquired  under  the  Plan  by  persons  who  are  not  affiliates  of
the  Company;  provided,  however,  that  all  employees  are  subject  to  the
Company’s policies against insider trading, and restrictions against resale may
be  imposed  by  the  Company  from  time-to-time  as  may  be  necessary  under
applicable law.

6.

Beneficiary

You  may  designate  a  beneficiary  to  receive  any  portion  of  your  Performance
Units and Restricted Share Units that become due to you after your death, and
you  may  change  your  beneficiary  from  time  to  time.    Beneficiary  designations
should be filed with the Broker with respect to Performance Units and Restricted
Share Units.   The beneficiary if you fail to file a designation with the Broker for
the Performance Units and the Restricted Share Units, will be (1) the beneficiary
you designated under any group life

Appendix A

-10-

insurance plan maintained by the Company or its Subsidiaries that provides the
largest  death  benefit,  which  will  constitute  the  designated  beneficiary  for
purposes  of  this  Section  IV.6,  or,  if  none,  (2)  the  executor  or  administrator  of
your estate.

7.

Effect on Other Benefits

Income  recognized  by  you  as  a  result  of  the  grant,  vesting,  exercise  or
distribution of Shares with respect to Awards will not be included in the formula
for  calculating  benefits  under  any  of  the  Company’s  retirement  and  disability
plans or any other benefit plans.

8.

Code Section 409A Compliance

(a)

(b)

The  award  of  Performance  Units  under  Section  I  is  intended  to  be
exempt  from  or  to  comply  with  the  provisions  of  Section  409A  and,
wherever  possible,  shall  be  consistent  therewith.    No  action  taken  to
comply with Section 409A shall be deemed to impair a benefit under the
Award Letter or this Appendix A.

interpreted  consistent 

The award of Restricted Share Units under Section II is intended to be
exempt  from  or  to  comply  with  the  provisions  of  Section  409A  and,
wherever  possible,  shall  be 
therewith.
 Specifically, (1) if you are not Retirement Eligible, the time of payment
specified in Sections II.2 and II.4 is exempt from Code Section 409A as
a  short  term  deferral  in  compliance  with  U.S.  Treasury  Regulation
Section 1.409A-1(b)(4), and (2) if you are Retirement Eligible the time of
payment  specified  with  respect  to  Section  II.4(b)  is  compliant  with  U.S.
Treasury Regulation Section 1.409A-3(a)(1) and is compliant with Code
Section 409A as being paid pursuant to a permissible payment date of
separation from service under U.S. Treasury Regulation Section 1.409A-
1(h) and the time of payment specified in Section II.4(a) with respect to
Disability  is  compliant  with  U.S.  Treasury  Regulation  Section  1.409A-
3(a)(2) and is compliant with Code Section 409A as being paid pursuant
to  the  permissible  payment  event  of  disability  under  U.S.  Treasury
Regulation  Section  1.409A-3(i)(4).    If  you  are  Retirement  Eligible,  you
will  not  be  considered  to  have  a  termination  from  employment  unless
such termination meets the requirements for a “separation from service”
within  the  meaning  of  U.S.  Treasury  Regulation  Section  1.409A-1(h),  if
applicable.    If  you  are  a  “specified  employee”  on  the  date  of  your
“separation from service” within the meaning of Code Section 409A, the
time of payment otherwise specified in the Award Letter or this Appendix
A  will  be  deferred  to  the  extent  required  by  Code  Section  409A.    No
action  taken  to  comply  with  Code  Section  409A  shall  be  deemed  to
impair a benefit under the Award Letter or this Appendix A.

Appendix A

Exhibit “A” to Performance Unit Award

A. Weighting of Total Target Performance Units

Total Earned Performance Units will be based on achievement of relative TSR performance,
subject  to  an  adjustment  based  on  the  Company’s  absolute  TSR.    Your  total  Earned
Performance  Units,  if  any,  will  be  the  number  of  Target  Performance  Units  that  become
Earned Performance Units, with 20% of the Total Target Performance Units weighted to each
of  the  Calendar  Performance  Periods,  and  40%  of  the  Total  Target  Performance  Units
weighted  to  the  Cumulative  Performance  Period.    The  maximum  number  of  Earned
Performance  Units  that  you  may  receive  is  200%  of  the  Total  Target  Performance  Units
described  in  your  Award  Letter.    If  any  calculation  with  respect  to  the  Earned  Performance
Units  would  result  in  a  fractional  share,  the  numbers  of  Earned  Performance  Units  shall  be
rounded down to the nearest whole share.

B. Committee Methodology for TSR

The  Committee  will  make  a  determination  on  the  Determination  Date  with  respect  to  the
achievement of TSR (as defined under Section C below) by the Company and the members of
its peer group (as described under Section C below) and the number of Target Performance
Units,  if  any,  that  become  Earned  Performance  Units  based  on  achievement  of  Relative
Performance and Threshold Performance (as those terms are defined below).

“Relative  Performance”  shall  be  determined  by  ranking  the  Company,  along  with  the  other
companies  in  its  peer  group,  from  best  to  worst  based  on  TSR,  and  then  determining  the
percentile ranking to assess the number of Earned Performance Units as described below.

If,  during  the  applicable  Calendar  or  Cumulative  Performance  Period,  (i)  any  peer  group
company files for or is the subject of any bankruptcy, insolvency or liquidation proceeding, (ii)
any peer group company continues to exist but is no longer publicly traded on an established
securities market as a result of a de-listing event (other than due to an acquisition), or (iii) any
other  corporate  financial  restructuring  event,  condition  or  circumstance  exists  that,  in  the
determination of the Committee, causes a peer performance to no longer be appropriate for a
TSR  comparison,  such  peer  group  company  will  remain  in  the  peer  group  positioned  below
the  lowest  performing  member  of  the  peer  group  in  chronological  order  by  the  date  of  such
bankruptcy, insolvency, liquidation, de-listing or other event, condition or circumstance for the
applicable period.  In the event that a peer group company is subject to a transaction in which
more  than  50%  of  the  value  of  the  company’s  outstanding  shares  immediately  prior  to  the
transaction are acquired by another person or entity, such company shall be removed from the
peer group company listing for the applicable period in which the transaction occurred.  

The  Company’s  percentile  ranking  in  its  peer  group  shall  determine  the  number  of  TSR
Performance  Units  that  become  Earned  Performance  Units  due  to  Relative  Performance
based on the following schedule:

Transocean Percentile

90th Percentile or Greater

50th Percentile

25th Percentile

Less than 25th Percentile

Percentage of TSR Performance Units Becoming
Earned Performance Units (“Relative
Performance”)

200%

100%

50%

0%

Appendix A

-12-

For any achievement of a percentile ranking between the percentiles set forth in the schedule
above, the number of Total Performance Units that become Earned Performance Units due to
Relative  Performance  will  be  determined  by  linear  interpolation  between  the  percentages
assigned in the schedule above.

If  the  Company’s  absolute  TSR  is  less  than  -15%  in  any  of  the  Calendar  or  Cumulative
Performance  Periods,  then  no    more  than  100%  of  your  Performance  Units  will  become
Earned Performance Units in the relevant period.  

If  the  Company’s  absolute  TSR  is  greater  than  15%  in  any  of  the  Calendar  or  Cumulative
Performance  Periods  (“Threshold  Performance”),  a  minimum  of  50%  of  your  Performance
Units  will  become  Earned  Performance  Units  in  the  relevant  period.  If  the  Threshold
Performance  is  achieved,  the  total  number  of  Earned  Performance  Units  can  be  increased,
but  not  decreased,  based  on  achievement  of  Relative  Performance  for  the  Calendar
Performance Periods and the Cumulative Performance Period.

Notwithstanding the foregoing, a “Price Cap” will apply such that if the Fair Market Value of a
Share  exceeds  $20,  subject  to  adjustment  pursuant  to  Section  15  of  the  Plan,  on  the
applicable Determination Date at the end of the Cumulative Performance Period, the number
of  Performance  Units  that  would  have  become  Earned  Performance  Units  due  to  either  the
Relative Performance or Threshold Performance will be reduced by multiplying such number
of  Earned  Performance  Units  by  a  fraction,  the  numerator  of  which  is  $20,  subject  to
adjustment  pursuant  to  Section  15  of  the  Plan,  and  the  denominator  of  which  is  the  Fair
Market  Value  of  a  Share  on  the  Determination  Date.    If  the  Price  Cap  applies,  delivery  of  a
number of Shares equal to such reduced number of Earned Performance Units will be in full
satisfaction of the Performance Units.  As an example of the application of the Price Cap, if
100 Performance Units would become Earned Performance Units based on the schedule due
to  Relative  Performance  and  the  Fair  Market  Value  of  a  Share  is  $25  on  the  Determination
Date, 80 Shares will be delivered in settlement of the Performance Units (100 x 20/25).

C. Definition of Total Shareholder Return

Total Shareholder Return (“TSR”) through the Calendar or Cumulative Performance Period is
based on the comparison of the average closing share price for the thirty (30) business days
prior to start of the applicable Calendar or Cumulative Performance Period and the average
closing share price for the last thirty (30) business days in the applicable Performance Period,
adjusted for dividends.  The same calculation is conducted for the Company and each of the
companies in the peer group.

D. Peer Group

The peer group shall consist of:

Inc.
Noble Corporation Plc
NOV Inc.
