OUR GLOBAL MARKET PRESENCEMidwaterUltra-Deepwater31134Harsh EnvironmentMarch 11, 2019 

Letter to Shareholders 

To the owners of our company: 

2018  will  be  remembered  as  a  transformative  year  in  Transocean’s  long  and  storied  history.  Among  other 
things: 

●  We expanded and enhanced our fleet through three separate strategic acquisitions, further strengthening 

our industry-leading position in the ultra-deepwater and harsh environment floater markets.   

●  We bolstered our backlog by booking 37 new floater fixtures in 2018, adding 19 rig years, and almost $2 

billion in future work, our highest total since 2014. 

●  We entered into an agreement with Chevron to construct and operate the industry’s most technically 
capable ultra-deepwater drillship, and the first equipped with subsea equipment rated to 20,000 psi.   

●  We  continued  to  strengthen  our  balance  sheet  and  extend  our  liquidity  runway  through  five  discrete 

opportunistic financing transactions. 

We accomplished all of this while delivering safe and efficient operations, including a full year without a single 
lost time incident, and the highest Revenue, Adjusted EBITDA and Adjusted EBITDA Margin for 2018 among 
all offshore drilling contractors. 

We believe that 2018 may also be remembered as the start of the recovery in the offshore market. Buoyed by 
strong and relatively stable oil prices over the first three quarters of 2018, many of our customers generated 
record  cash  flows  from  operations,  providing  them  with  the  liquidity  that  they  needed  to  fund  dividends, 
repurchase their own shares, service debt and invest in longer cycle offshore projects. This incremental cash, 
coupled  with  dramatically  reduced  breakeven  costs  per  barrel  for  offshore  projects,  and  rapidly  declining 
reserve replacement ratios, led to a tangible increase in year-over-year contracting activity. 

Even though oil prices declined sharply in the fourth quarter of 2018, creating temporary uncertainty across the 
industry, we continue to expect increased levels of contracting activity as we progress through 2019. Oil prices 
have  rebounded  to  start  the  year,  with  Brent  crude  trading  above  $60  per  barrel,  and  our  recent  customer 
engagements suggest that they are undeterred by the year-end volatility in commodity prices. However, we 
remain acutely aware that price instability could delay offshore projects currently planned for the back half of 
2019,  2020  and  2021.  As  such,  we  will  maintain  our  disciplined  approach  as  we  continue  to  enhance  our 
leadership  position  and  prepare  Transocean  to  capitalize  on  the  incremental  demand  that  we  expect  to 
ultimately materialize in the ultra-deepwater market.             

In preparation for that recovery, we will continue to be prudent as we take the necessary actions to strategically 
position Transocean to outperform throughout the cycle. 

We continue to strengthen our fleet of high-specification assets through newbuilds, acquisitions and 
divestitures – further enhancing our industry-leading harsh environment and ultra-deepwater fleet. In 
February 2018, the Deepwater Poseidon, the fourth and final contract-backed Shell newbuild, commenced its 
ten-year contract in the Gulf of Mexico. In addition to adding the Poseidon to our operating fleet during 2018, 
we closed three significant transactions – the acquisitions of Songa Offshore SE and Ocean Rig UDW Inc and 
an  investment  in  a  joint  venture  to  acquire,  complete,  market  and  operate  the  Transocean  Norge,  a  harsh 

 
 
 
 
 
LETTER TO SHAREHOLDERS 

environment  semi-submersible  drilling  rig.  The  high-specification  assets  associated  with  all  three  of  these 
transactions are preferred by our customers and position us to best capitalize on a market recovery.   

The  Songa  acquisition  added  four  high-specification,  fit-for-purpose  harsh  environment  semi-submersible 
drilling rigs to our fleet, while bolstering our backlog with $3.8 billion of long-term contracts.   

The Ocean Rig acquisition added ten high-specification ultra-deepwater drillships to our fleet, including two 
world-class assets currently under construction, with deliveries scheduled for 2019 and 2020. This provides us 
with more of the highly efficient assets that our customers favor.   

Lastly, our 33% investment in the joint venture that acquired the Transocean Norge secured us the exclusive 
marketing and operating rights to one of the industry’s most capable harsh environment semi-submersibles.   
We have now taken delivery of this rig, and she is scheduled to commence her maiden contract in the second 
quarter of 2019.   

We have also furthered the high-grading of our fleet through the recycling of ten older, less-competitive assets 
since  the  beginning  of  2018,  bringing  our  total  over  the  past  five  years  to  48  floaters.  When  offset  by  the 
newbuilds, and rigs added through acquisitions over those same five years, we now have a fleet of 48 floaters, 
including 31 ultra-deepwater, 13 harsh environment, and four midwater floaters.         

While we will continue to evaluate our fleet and consider opportunities to enhance it, we are pleased to have 
assembled  the  largest  and  highest-specification  ultra-deepwater  and  harsh  environment  floater  fleet  in  the 
industry. 

We continue to add new contracts to our backlog, including a contract to construct and operate the 
industry’s  highest  specification  ultra-deepwater  drillship.  Over  the  course  of  2018,  Transocean  added 
almost $2 billion of new backlog by securing 37 awards. By comparison to the prior year, this represents a 
222% increase in total dollars booked, and a 144% increase in total contracts awarded. Of note, our 37 new 
fixtures in 2018 represented 21% of the total floater contracts awarded in 2018, the most of any offshore driller, 
clearly  suggesting  that  our  customers  prefer  our  high-specification  assets,  our  history  of  performance  in 
challenging  environments,  and  our  flexible  approach  to  contracting  arrangements,  including  performance-
driven models. Importantly, because of Transocean’s global reach, during 2018, we secured contracts in every 
major market, including the U.S. Gulf of Mexico, Canada, Brazil, West Africa, the United Kingdom, Norway, 
India, Southeast Asia and Australia. 

The most notable of those contract awards was realized in late December, when we entered into an agreement 
with Chevron to construct and operate the industry’s most technically capable drillship, which will incorporate 
state-of-the-art  technology,  including  dual  20,000  psi  blowout  preventers,  a  first  for  ultra-deepwater 
applications, a derrick with gross hoisting capacity of 3.4 million pounds, a variable deckload capacity of 24,000 
metric tons, and an enhanced dynamic positioning system. The five-year drilling contract for this rig added an 
estimated $830 million to our already industry-leading backlog and represents the largest single contract any 
offshore  driller  has  entered  into  since 2012.  More  than  any other  award,  this contract  is  a testament  to the 
confidence that our customers have in Transocean’s ability to safely, efficiently and successfully deliver new 
game-changing  technology  to  the  industry,  enabling  our  customers  to  drill  and  complete  wells  in  reservoirs 
previously deemed inaccessible.   

We remain committed to maintaining our balance sheet flexibility. In 2018, through various opportunistic 
transactions, we issued approximately $3.0 billion of debt with maturities between 2023 and 2025, while retiring 
$2.1 billion of debt with maturities primarily between 2018 and 2022. Additionally, we successfully entered into 
a new $1 billion five-year undrawn revolving credit facility, including a $500 million accordion feature. As a direct 
result of these transactions and outstanding operational performance, we exited 2018 with $2.2 billion in cash 
and short-term investments and a $1 billion undrawn revolving credit facility. Therefore, we enter 2019 with 
sufficient liquidity to continue to navigate the current market environment, while also continuing to invest in our 
fleet, people and strategy. 

 
LETTER TO SHAREHOLDERS 

We  continue  to  focus  on  differentiation  and  operational  excellence.  In  2018,  we  continued  to  make 
advancements  in  the  development  of  several  new  technologies  designed  to  improve  safety,  equipment 
reliability, and drilling efficiency. We also made progress in commercializing technology engineered to reduce 
a rig’s fuel consumption and carbon footprint, which we will begin deploying to select rigs in 2019.     

We fully recognize that we must continue to realize opportunities to improve our customers’ economics through 
more efficient well delivery; thus, we continue to explore new technologies and processes to safely reduce the 
time required to drill and complete wells.   

Entering 2019, we are prepared to execute more rig reactivations and rig moves than we have in the recent 
past; therefore, in addition to focusing on new technology and process redesign, we are thoroughly focused on 
flawless  and  timely  reactivations.  This  includes  an  acute  focus  on  delivering  incident-free  operations  and 
superior uptime performance, beginning day one of the campaign. We believe that efficient reactivations will 
be critical in  differentiating Transocean in the eyes of our customers and are working intently with both  the 
shipyards and our equipment providers to thoughtfully plan and execute each project. 

We remain committed to corporate sustainability. In 2018, we introduced the first sustainability report in 
Transocean’s history. In this report, we captured our 2016 baseline performance and communicated our 2022 
goals  for:  Personal  Safety,  Environmental  Impact,  Innovation  and  Technology,  Operational  and  Financial 
Performance, Diversity and Development, and Community Support. While our 2022 goals are ambitious, the 
organization is committed to taking the actions required to deliver our stated objectives.     

We  look  forward  to  2019.  While  the  volatility  in  oil  prices  over  the  final  months  of  2018  created  some 
uncertainty,  we  remain  encouraged  by  the  strategic  direction  we  have  taken  at  Transocean  and  the 
opportunities we believe will continue to emerge in the offshore deepwater market. Supporting our position: 

●  Our customers generated record cash flows in 2018, providing them the flexibility  to return capital to 

shareholders, service debt and invest in longer cycle offshore projects.   

●  Offshore  project  breakeven  costs  per  barrel  continue  to  trend  lower  and  are  demonstrating  superior 

economics to other opportunities in our customers’ portfolios. 

●  Our customers need to replace their longer-term production and reserve base. 

We believe that the combination of these three facts should drive a material increase in offshore drilling activity 
in 2019 and beyond. 

We also are pleased to announce that Chadwick C. “Chad” Deaton, a member of our Board since 2012, is 
being nominated to succeed our current Chairman, Merrill A. “Pete” Miller, who will not stand for re-election to 
the Board. Chad joined our Board before his retirement in 2013 from his role as Executive Chairman of Baker 
Hughes, where he also served eight years as Chairman, President and Chief Executive Officer. Chad has more 
than 30 years of experience in the oilfield service industry. We thank Pete for his significant contributions to the 
success of Transocean over the past five years and look forward to Chad’s leadership going forward. 

We thank you, our shareholders, on behalf of our entire team at Transocean, for your continued support and 
trust. We look forward to further strengthening this great company as we enter the recovery.

regulations. 

Swiss Minder Ordinance 

Under the Swiss Ordinance Against Excessive Compensation At Public Companies (the “Minder Ordinance”) 
and our Articles of Association, the authority to elect the Chairman of the Board of Directors and the members 
of  the  Compensation  Committee  is  vested  in  the  general  meeting  of  shareholders.  The  Board  of  Directors 
recommends that you elect Chadwick C. Deaton as Chairman of the Board of Directors (Agenda Item 5) and 
Frederico F. Curado, Vincent J. Intrieri and Tan Ek Kia as members of the Compensation Committee (Agenda 
Item 6) to serve until completion of the 2020 annual general meeting of the shareholders (the “2020 Annual 
General  Meeting”).  Note that  under  the  Minder  Ordinance  and  our  Articles  of  Association,  if  any  of  these 
individuals were to resign or there were vacancies in the office of the Chairman or the Compensation Committee 
for other reasons, the Board of Directors would have the authority to replace him or her with another member 
of the Board of Directors for a term expiring at the next annual general meeting. 

Pursuant to the Minder Ordinance, the Company is not permitted to appoint a corporate representative to act 
as the proxy for purposes of voting at the 2019 Annual General Meeting. Swiss companies may only appoint 
an independent proxy for these purposes. At the 2018 annual general meeting of the shareholders (the “2018 
Annual General Meeting”), shareholders elected Schweiger Advokatur / Notariat to serve as our independent 
proxy for a term extending until the completion of the 2019 Annual General Meeting. Agenda Item 7 asks that 
you  again  elect  this  firm  to  act  as  the  independent  proxy  for  the  2020  Annual  General  Meeting  and  any 
extraordinary  general  meeting  of  shareholders  of  the  Company  that  may  be  held  prior  to  the  2020  Annual 
General Meeting. 

The Minder Ordinance and our Articles of Association also require that the shareholders ratify the maximum 
aggregate amount of compensation of the Board of Directors for the period between the 2019 Annual General 
Meeting and the 2020 Annual General Meeting (Agenda Item 10A) and the maximum aggregate amount of 
compensation of the Executive Management Team for fiscal year 2020 (Agenda Item 10B). The shareholder 
vote is binding. 

Features of Executive Compensation Program 

Our executive compensation program reflects a commitment to retain and attract highly qualified executives. 
The elements of our program are designed to motivate our executives to achieve our overall business objectives 
and  create  sustainable  shareholder  value  in  a  cost-effective  manner  and  reward  executives  for  achieving 
superior financial, safety and operational performance, each of which is important to the long-term success of

PROXY STATEMENT SUMMARY 

the Company. We believe our executive compensation program includes key features that align the interests 
of our executives with those of our shareholders and does not include features that could impair that alignment. 

What We Do 

✓    Conduct an annual review of our compensation 
strategy, including a review of our compensation-
related risk profile

(1)    Affirmative vote of a simple majority of the votes cast in person or by proxy at the 2019 Annual General Meeting on
the applicable agenda item. Abstentions, broker non-votes (if any) or blank or invalid ballots are not counted for such 
purposes and shall have no impact on the approval of such agenda item. 

(2)    Affirmative vote of a plurality of the votes cast in person or by proxy at the 2019 Annual General Meeting. The plurality
requirement means that the nominee who receives the largest number of votes for a position as a director, or the chair
or a position on the Compensation Committee, as applicable, is elected to that position. Only votes “FOR” are counted
in determining whether a plurality has been cast in favor of a nominee. Abstentions, broker non-votes, blank or invalid 
ballots are not counted for such purposes and shall have no impact on the election of such nominees. As described
later in this proxy statement, our Corporate Governance Guidelines set forth our procedures if a nominee for director
is elected but does not receive more votes cast “FOR” than “AGAINST” the nominee’s election. 

(3)    The proposal is an advisory vote; as such, the vote is not binding on the Company. 

(4)    Even if a nominee receives a plurality of votes that nominee may not ultimately serve as a director if the nominee does
not receive more votes cast “FOR” than “AGAINST” the nominee’s election, and the Company’s Board of Directors
accepts the resignation of the nominee pursuant to the Company’s majority vote policy, as described later in this proxy
statement.

Transocean Ltd. for Fiscal Year 2018 and the Audited Statutory Financial Statements of 
Transocean Ltd. for Fiscal Year 2018 

Proposal of the Board of Directors 

The  Board  of  Directors  proposes  that  the  2018  Annual  Report,  including  the  audited  consolidated  financial 
statements  of  Transocean Ltd.  for  fiscal year  2018  and  the  audited  statutory  financial  statements  of 
Transocean Ltd. for fiscal year 2018, be approved. 

Explanation 

The audited consolidated financial statements of Transocean Ltd. for fiscal year 2018 and the audited Swiss 
statutory financial statements of Transocean Ltd. for fiscal year 2018 are contained in the 2018 Annual Report, 
which, along with this proxy statement, is available at:  www.deepwater.com by selecting Financial Reports, 
Annual and Quarterly Reports in the Investors section dropdown. In addition, these materials will be available 
for physical inspection at the Company’s registered office, Turmstrasse 30, CH-6312 Steinhausen, Switzerland. 
The 2018 Annual Report also contains information on the Company’s business activities and the Company’s 
business and financial situation, and the reports of Ernst & Young Ltd, Zurich, the Company’s auditors pursuant 
to the Swiss Code of Obligations, on the Company’s consolidated financial statements for fiscal year 2018 and 
statutory  financial  statements  for  fiscal year  2018.  In  its  reports,  Ernst &  Young Ltd  recommended  without 
qualification  that  the  Company’s  consolidated  financial  statements  and  statutory  financial  statements  for 
the year  ended  December 31,  2018,  be  approved.  Ernst &  Young Ltd  expresses  its  opinion  that  the 
“consolidated  financial  statements  for  the years  ended  December 31,  2018  and  2017  present  fairly  in  all 
material respects the consolidated financial position of Transocean Ltd. and subsidiaries at December 31, 2018 
and 2017, and the consolidated results of operations and cash flows for each of the three years in the period 
ended December 31, 2018, in accordance with accounting principles generally accepted in the United States 
and comply with Swiss law.” Ernst & Young Ltd further expresses its opinion and confirms that the statutory 
financial statements for fiscal year 2018 comply with Swiss law and the Articles of Association of the Company. 

Under  Swiss  law,  the  annual  report,  the  consolidated  financial  statements  and  Swiss  statutory  financial 
statements must be submitted to shareholders for approval at each annual general meeting. 

If  the  shareholders  do  not  approve  this  proposal,  the  Board  of  Directors  may  call  an  extraordinary  general 
meeting of shareholders for reconsideration of this proposal by shareholders.

The Board of Directors recommends a vote “FOR” this Agenda Item 1.

AGENDA ITEM 2 

Discharge of the Members of the Board of Directors and the Executive Management Team from 
Liability for Activities During Fiscal Year 2018 

Proposal of the Board of Directors 

The Board of Directors proposes that the members of the Board of Directors and Messrs. Jeremy D. Thigpen, 
Mark L. Mey, Keelan I. Adamson and John B. Stobart, who served as members of our Executive Management 
Team in 2018, be discharged from liability for activities during fiscal year 2018. 

Explanation 

As is customary for Swiss corporations and in accordance with Article 698, subsection 2, item 5 of the Swiss 
Code of Obligations, shareholders are requested to discharge the members of the Board of Directors and our 
Executive Management Team from liability for their activities during the past fiscal year. 

Discharge pursuant to the proposed resolution is only effective with respect to facts that have been disclosed 
to shareholders (including through any publicly available information, whether or not included in our filings with 
the SEC) and only binds shareholders who either voted in favor of the proposal or who subsequently acquired 
shares with knowledge that the shareholders have approved this proposal. In addition, shareholders who vote 
against this proposal, abstain from voting on this proposal, do not vote on this proposal, or acquire their shares 
without  knowledge  of  the  approval  of  this  proposal,  may  bring,  as  a  plaintiff,  any  claims  in  a  shareholder 
derivative suit within six months after the approval of the proposal. After the expiration of the six-month period, 
such shareholders will generally no longer have the right to bring, as a plaintiff, claims in shareholder derivative 
suits  against  members  of  the  Board  of  Directors  or  Executive  Management  Team  with  respect  to  activities 
during fiscal year 2018.

AGENDA ITEM 4 

Reelection of 10 Directors, Each for a Term Extending Until Completion of the Next Annual General 
Meeting 

Nominations of the Board of Directors 

The Board of Directors has nominated Glyn A. Barker, Vanessa C.L. Chang, Frederico F. Curado, Chadwick 
C. Deaton, Vincent J. Intrieri, Samuel J. Merksamer, Frederik W. Mohn, Edward R. Muller, Tan Ek Kia and 
Jeremy D. Thigpen for reelection to the Board of Directors of the Company, each for a term extending until 
completion of the next annual general meeting. 

The Board of Directors does not have a specific policy regarding diversity in the selection of director nominees. 
However, the Board of Directors does consider diversity in the director nominee selection process. The Board 
of Directors takes an expansive view of the diversity of its members, with the goal of having directors who bring 
diverse expertise in environmental, health, safety, industry, market and financial matters and who reflect the 
global diversity of our workforce, our customers and the cultures in which we operate. We are a multinational 
company with eight different nationalities represented in our director and executive officer group and over 55 
in our global workforce. We have a presence in over 32 countries worldwide. 

Voting Requirement to Elect Nominees 

The election of each nominee requires the affirmative vote of a plurality of the votes cast in person or by proxy 
at  the  2019  Annual  General  Meeting.  The  plurality  requirement  means  that  the  nominee  who  receives  the 
largest number of votes for a board seat is elected. Shareholders are entitled to one vote per share for each of 
the directors to be elected. 

We  have  adopted  a  majority  vote  policy  in  the  election  of  directors  as  part  of  our  Corporate  Governance 
Guidelines. This policy provides that the Board of Directors 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  more  votes  cast  “FOR”  than  “AGAINST”  his  or  her  election  in  an 
uncontested election and (2) the Board of Directors accepts the resignation. 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 
of Directors whether to accept the tendered resignation or reject it. The Board of Directors must then act on the 
Corporate  Governance  Committee’s  recommendation  within  90 days  following  the  certification  of  the 
shareholder vote. The Board of Directors must promptly disclose its decision regarding whether or not to accept 
the nominee’s resignation letter in a Form 8-K furnished to the SEC or other broadly disseminated means of 
communication.  Full  details  of  this  policy  are  set  out  in  our  Corporate  Governance  Guidelines,  which  are 
available on our website at: www.deepwater.com by selecting the Governance page in the Investors section 
dropdown. 

The Board of Directors has received from each nominee for election as a director at the 2019 Annual General 
Meeting listed below an executed irrevocable letter of resignation consistent with these guidelines described 
above. Each letter of resignation is effective only in the event that (1) such director fails to receive a sufficient 
number of votes from shareholders in an uncontested election of such director and (2) the Board of Directors 
accepts such resignation. 

The information regarding the nominees presented below is as of March 8, 2019.

Audit Committee Pre-Approval of Audit and Non-Audit Services 

The Audit Committee pre-approves all auditing services, review or attest engagements and permitted non-audit 
services  to  be  performed  by  our  independent  registered  public  accounting  firm.  The  Audit  Committee  has 
considered whether the provision of services rendered in 2018 other than the audit of our financial statements 
and reviews of quarterly financial statements was compatible with maintaining the independence of Ernst & 
Young LLP  and  determined  that  the  provision  of  such  services  was  compatible  with  maintaining  such 
independence. 

The Audit Committee has adopted policies and procedures for pre-approving all audit and non-audit services 
performed by the independent registered public accounting firm. The policy requires advance approval by the 
Audit Committee of all audit and non-audit work; provided, that the Chairman of the Audit Committee may grant 
pre-approvals  of  audit  or  non-audit  work,  so  long  as  such  pre-approvals  are  presented  to  the  full  Audit 
Committee at its next scheduled meeting. Unless the specific service has been previously pre-approved with

Committee has given advance approval for specified audit, audit-related and other services for 2019. Requests 
for services that have received this pre-approval are subject to specified fee or budget restrictions, as well as 
internal management controls.

AGENDA ITEM 9 

Advisory Vote to Approve Named Executive Officer Compensation 

Proposal of the Board of Directors 

At the Company’s 2017 Annual General Meeting, the Company’s shareholders followed the Board of Directors’ 
recommendation to hold an advisory vote on executive compensation every year for the Company’s Named 
Executive Officers. In light of these results, the Board of Directors determined that the Company will hold an 
advisory  vote  on  executive  compensation  once  every  year  until  the  next  required  vote  on  the  frequency  of 
shareholder votes on compensation of Named Executive Officers of the Company, which in accordance with 
applicable  law,  will  occur  no  later  than  the  Company’s  annual  general  meeting  of  shareholders  in  2023. 
Accordingly, and as required by Section 14A of the Exchange Act, the Company is providing its shareholders 
the opportunity to vote on an advisory basis to approve the compensation of the Company’s Named Executive 
Officers. The Board of Directors recommends that you vote for the approval of the compensation of the Named 
Executive Officers as described in this proxy statement. 

Accordingly, you may vote on the following resolution: 

RESOLVED, that the compensation of the Company’s Named Executive Officers, as disclosed pursuant to the 
compensation  disclosure  rules of  the  SEC,  including  the  Compensation  Discussion  and  Analysis,  the 
compensation  tables,  and  the  narrative  disclosure  in  the  proxy  statement  for  the  Company’s  2019  Annual 
General Meeting is hereby APPROVED. 

Our compensation program for our Named Executive Officers is designed to reward performance that creates 
long-term value for the Company’s shareholders through the following features, which are discussed in more 
detail in our Compensation Discussion and Analysis: 

●  Annual cash bonuses based on performance as measured against pre-determined performance goals; 

●  A  compensation  mix  weighted  toward  long-term  incentives  to  allow  our  Named  Executive  Officers  to 

participate in the long-term growth and profitability of the Company; 

●  Long-term  incentives  include  performance  share  units  that  vest  based  upon  the  Company’s  total 

shareholder return compared to the companies in our performance peer group; 

●  Median pay positioning for target performance, above median pay for above target performance, and 

below median pay for below target performance; 

●  A share ownership policy that requires our executive officers to build and maintain an appropriate equity 
stake in the Company to further align our executive officers’ interests with the long-term interests of our 
shareholders; 

●  Hedging and pledging policies that prohibit any of our executive officers from hedging or pledging our 
shares or holding derivative instruments tied to our shares, other than derivative instruments issued by 
us; and 

●  The Incentive Compensation Recoupment Policy, a clawback policy that allows the Company to recover 
or adjust incentive compensation to the extent the Compensation Committee determines that payments 
or awards have exceeded the amount that would otherwise have been received due to a restatement of 
our financial results or if the Compensation Committee determines that an executive has engaged in, or 
has  knowledge  of  and  fails  to  prevent  or  disclose,  fraud  or  intentional  misconduct  pertaining  to  any 
financial reporting requirements. 

The vote on this proposal is advisory and therefore not binding on the Company, the Compensation Committee 
or the Board of Directors. The Board of Directors and the Compensation Committee value the opinions of our 
shareholders. Following the 2019 Annual General Meeting, we will consider our shareholders’ feedback and 
the Compensation Committee will evaluate whether any actions are necessary to address this feedback.

found under “Board Meetings and Committees—Director Compensation Strategy.” The actual amounts paid to 
each member of the Board of Directors for fiscal year 2018 are disclosed under “2018 Director Compensation” 
and in our Swiss Compensation Report under the caption “Board of Directors’ Compensation.” 

Proposal for Ratification of Maximum Aggregate Amount 

The Board of Directors proposes that the shareholders ratify an amount of U.S. $4,121,000 as the maximum 
aggregate  amount  of  compensation  of  the  Board  of  Directors  for  the  2019/2020  Term.  This  amount  is  the 
maximum  amount  that  the  Company  can  pay  or  grant  to  the  members  of  the  Board  of  Directors  for  the 
2019/2020  Term.  The  proposed  aggregate  maximum  amount  has  been  calculated  based  on  the  directors’ 
compensation elements as outlined above. 

The table below shows the aggregate compensation paid to our Board of Directors for the 2017/2018 Term, 
and the shareholder-approved, maximum aggregate compensation payable to our Board of Directors for the 
2018/2019 Term. The 2017/2018 and 2018/2019 Terms include ten non-employee directorships, one of whom 
was Chairman of the Board of Directors. Further, the table explains our proposal for the maximum aggregate 
amount of compensation for our Board of Directors for the 2019/2020 Term. This proposal is unchanged from

Recommendation 

The Board of Directors recommends that you vote “FOR” this Agenda Item 10A. 

10B  Ratification  of  the  Maximum  Aggregate  Amount  of  Compensation  of  the  Executive 

Management Team for Fiscal Year 2020. 

Proposal of the Board of Directors 

The Board of Directors proposes that the shareholders ratify an amount of U.S. $24,000,000 as the maximum 
aggregate amount of compensation of the Executive Management Team for fiscal year 2020. 

Explanation 

As  required  by  our  Articles  of  Association  and  the  Minder  Ordinance,  our  shareholders  are  provided  the 
opportunity to vote on the maximum aggregate amount of compensation that can be paid or granted to the 
members of the Executive Management Team for fiscal year 2020. The shareholder vote is of binding nature.

AGENDA ITEM 10 

Executive Management Team Compensation Principles 

The general principles of the compensation for the Executive Management Team are described in article 29b 
of our Articles of Association. 

We use a combination of cash and equity compensation to attract, motivate and retain leaders from the global 
executive talent market within and outside our highly competitive industry and to achieve our objective of pay 
and performance alignment by delivering the vast majority of our Executive Management Team’s compensation 
opportunity as performance-based, ‘at-risk’ compensation. Our Executive Management Team’s compensation 
consists of (1) base salary, (2) annual performance bonus, (3) long-term incentives, which may comprise grants 
of  restricted  share  units,  performance  share  units  and  stock  options  and  (4) other  compensation,  including 
Company contributions to savings and pension plans, life insurance premiums, dividend equivalents on vested 
and unvested restricted share units, expatriate assignment allowances and expatriate relocation pay. 

Our Executive Management Team comprises our President and Chief Executive Officer, our Executive Vice 
President and Chief Financial Officer, and our Executive Vice President and Chief Operations Officer. 

For  a  detailed  description  of  our  compensation  principles  currently  in  effect  for  the  Executive  Management 
Team (and our other Named Executive Officers who are not members of the Executive Management Team), 
please refer to the section of this proxy statement under the caption: “Compensation Discussion and Analysis.” 
We recommend that our shareholders read our Articles of Association and the Compensation Discussion and 
Analysis  to  understand  our  Executive  Management  Team  compensation  principles  and  process  when 
considering this proposal. The actual amounts paid to each member of the Executive Management Team for 
fiscal years 2016-2018 are disclosed in this proxy statement under the caption: “Executive Compensation—
Summary  Compensation  Table,”  and  in  our  Swiss  Compensation  Report  under  the  caption: “Executive 
Management Team Compensation.” 

In  addition  to  this  binding  prospective  vote  on  maximum  Executive  Management  Team  compensation, 
shareholders have had the opportunity since 2011 under U.S. law, subject to an advisory vote by shareholders 
and a determination by the Board of Directors as to the frequency of such opportunity, to cast a retrospective 
advisory  vote  to  approve  the  compensation  paid  to  our  Named  Executive  Officers  (including  our  Executive 
Management  Team  members)  for  the  fiscal year  preceding  the  Annual  General  Meeting.  Since  2011,  our 
shareholders  have  consistently  expressed  their  strong  support  for  the  Company’s  executive  compensation 
principles. For fiscal years 2011,  2012, 2013, 2014, 2015, 2016, and 2017,  the shareholder approval levels 
have been 86%, 81%, 92%, 80%, 87%, 96% and 97%, respectively. Our shareholders are again provided the 
opportunity to cast a retrospective advisory vote to approve the compensation paid to our Named Executive 
Officers (including our Executive Management Team members) for fiscal year 2018, as is explained in detail in 
Agenda Item No. 9. 

The  proposed  maximum  aggregate  amount  of  compensation  for  the  Executive  Management  Team  for 
fiscal year  2020  is  derived  substantially  from  the  Company’s  executive  compensation  principles  receiving 
strong  historical  shareholder  support  as  noted  above. Consistent  with  the  Company’s  historical  practice  in 
setting  executive  compensation,  as  reflected  in  the  Compensation  Discussion  and  Analysis,  we  do  not 
anticipate that the aggregate amount actually paid to our Executive Management Team members for fiscal year 
2020 will be at the proposed maximum aggregate amount. 

Proposal for Ratification of Maximum Aggregate Amount 

The  Board  of  Directors  proposes  that  the  shareholders  ratify  an  amount  of  U.S.  $24,000,000,  excluding 
employer-paid social taxes, as the maximum aggregate amount of compensation of the Executive Management 
Team  for  fiscal year  2020.  This  amount  is  unchanged  from  the  approved  maximum  aggregate  amount  of 
compensation  for  fiscal  year  2019,  and  is  the  maximum  amount  that  the  Company  can  pay  or  grant  to  its 
members  of  the  Executive  Management  Team  for  fiscal year  2020,  subject  to  the  authority  of  the  Board  of 
Directors to grant or pay a “supplementary amount” pursuant to article 29c of our Articles of Association without 
additional  shareholder  ratification  to  persons  who  newly  assume  an  Executive  Management  Team  function 
after the prospective vote at the 2019 Annual General Meeting.

The table below shows the maximum aggregate amount of compensation that could have been paid or granted 
in  the  fiscal year  2018  under  our  compensation  principles  and  plans,  the  maximum  aggregate  amount  of 
compensation available to be paid or granted for fiscal year 2019 under our compensation principles and plans 
currently in effect, and our proposed maximum aggregate amount of compensation for fiscal year 2020. 

The proposed maximum aggregate amount of compensation for fiscal year 2020 is based on our estimated 
compensation levels and is unchanged from the maximum aggregate amount of compensation for fiscal year 
2019, which was approved by shareholders at last year’s annual general meeting.

(1)     Assumes that the base salary, the annual performance bonus and all other compensation have been, or will be, paid or 
granted at the maximum level as provided under our compensation principles and plans (e.g., in relation to the annual 
performance bonus, assuming a payout of annual incentive bonuses at the maximum payout level of 200%). In relation 
to  the  long-term  incentive  plans,  the  fair  value  calculations  are  based  on  an  assumed  achievement  of  performance 
targets at 100%; see note 5 below for further information. 

(2)     The proposal of the Board of Directors for ratification by our shareholders only relates to the maximum aggregate amount 
of total compensation as shown in the “Total” row. The subtotals shown for each compensation category are included 
for illustration purposes only. 

(3)     Reflects actual base salaries paid to our Executive Management Team members.   
(4)     Reflects  actual  base  salaries  paid  to,  and  base  salaries  for  the  remaining  fiscal year  to  be  paid  to,  our  Executive 

Management Team members, based on base salary levels effective for fiscal year 2018. 

(5)     Based  on  individual  target  award  opportunities  and  maximum  payout  at  200%.  As  further  described  under 
“Compensation Discussion and Analysis—Annual Performance Bonus,” the potential payout ranges from 0% to 200% 
of the individual target award opportunity. Maximum payout is only available upon achievement of superior performance. 
Individual target award opportunities ranged, and will range, between 75% and 125% of the base salary, depending on 
the level of responsibility. 

(6)     Based on target amounts and fair value calculations. With regard to performance-based long-term incentives such as 
performance share units, the fair value calculations are based on an assumed achievement of performance targets at 
100%. For the 2020 grant cycle, the actual number of shares to be allocated under such long-term incentive plans will 
be determined in 2023 depending on performance achievement over a three-year performance cycle and may range 
between 0% to 200%. 

(7)     Assumes that all compensation has been paid or granted at the maximum level as provided under our compensation 
principles and plans. Mandatory employer-paid social taxes pursuant to applicable law are excluded from the proposed 
maximum amount. In 2018, employer-paid social taxes totaled U.S. $283,390. 

Shareholder approval is based on the maximum aggregate amounts that could be payable in accordance with 
our compensation principles as set out in the 2019 Proxy Statement’s “Compensation Discussion and Analysis.” 
Therefore, actual aggregate amounts paid to our Executive Management Team members for fiscal year 2020 
will  fall  within  the  range  that  may  be  payable.  And  although  historical  compensation  paid  to  our  Executive 
Management  Team,  as  disclosed  in  the  Compensation  Report,  has  been  substantially  less  (2018:  U.S. 
$17,050,273)  than  the  maximum  amount  payable  (2018:  U.S.  $24,000,000)  we  request  our  shareholders 
approve the proposed maximum aggregate amount in order to comply with our Articles of Association and to 
ensure that the authorized compensation is set at a level that allows us to honor our compensation obligations 
and promises under our compensation principles and plans if the Executive Management Team or its individual 
members deliver superior performance and achieve all of the performance objectives at maximum performance 
level. 

The 2020 Executive Management Team compensation will be disclosed in the proxy statement for our 2021 
annual general meeting and the Swiss Compensation Report for fiscal year 2020.

CORPORATE GOVERNANCE 

We are committed to upholding high standards of corporate governance and business conduct and believe that 
we have maintained good corporate governance practices for many years. 

We regularly review and, as necessary, update our Code of Integrity. Accordingly, in November 2016, the Board 
of Directors adopted a Code of Integrity that updated and replaced our previous Code of Integrity. We conduct 
online mandatory training for our employees and officers on our Code of Integrity and other relevant compliance 
topics. We also require all of our officers and managerial and supervisory employees to certify compliance with 
our Code of Integrity each year and to proactively report any non-compliance they may discover. 

The Corporate Governance Committee of the Board of Directors evaluates the Company’s and the Board of 
Directors’ governance practices and formally reviews all committee charters along with recommendations from 
the various committees of the Board of Directors and the Board of Directors’ governance principles at least 
annually.  The  Corporate  Governance  Committee  receives  updates  at  each  meeting  regarding  new 
developments  in  the  corporate  governance  arena.  Our  Corporate  Governance  Guidelines  and  committee 
charters also require, among other things, that each committee and the Board of Directors annually conduct a 
self-evaluation of their own performance. The evaluation provides an opportunity for an assessment of each 
member of the Board of Directors.   

Director  Share  Holding  Requirement.  We  have  equity  ownership  guidelines  for  directors  that  require  each 
current non-management director to acquire and retain a number of our shares, restricted share units and/or 
deferred units at least equal in value to an amount five times the director’s annual cash retainer. Each new 
director is required to acquire and retain such number of shares, restricted share units and/or deferred units 
over his or her initial five years as a director. Jeremy D. Thigpen, our President and Chief Executive Officer, is 
subject to separate officer share ownership guidelines providing for a more stringent requirement of six times 
his base pay. In connection with such ownership requirement, the Board of Directors currently grants restricted 
share units to each of our non-management directors. See “Compensation Discussion and Analysis” for more 
information about these guidelines. 

Restrictions on Pledging, Hedging and Margin Accounts. Pursuant to our Insider Trading Policy, employees, 
officers and directors are restricted from pledging, hedging or holding shares in a margin account.

We will continue to monitor our governance practices and update policies and procedures, as appropriate, in 
order to maintain our high standards. 

Board  Leadership.  Except  during  extraordinary  circumstances,  the  Board  of  Directors  has  chosen  not  to 
combine the positions of Chief Executive Officer and Chairman of the Board. The Board believes that separating 
these positions allows our Chief Executive Officer to focus on our day-to-day business, while our Chairman of 
the Board presides over the Board as it provides advice to, and independent oversight of, management and 
the Company’s operations. The Board recognizes the time, effort, and energy that our Chief Executive Officer 
is required to devote to his position and the additional commitment the position of Chairman of the Board of 
Directors requires. The Board of Directors believes that having separate positions and having an independent 
outside director serve as Chairman of the Board of Directors is the appropriate leadership structure for us at 
this time and demonstrates our commitment to good corporate governance. 

Risk Management. Executive management is responsible for the day-to-day management of the risks we face, 
while the Board of Directors, as a whole and through its various committees, has responsibility for the oversight 

P-38   Transocean 2019 Proxy Statement 

 
 
 
 
 
CORPORATE GOVERNANCE 

of  risk  management  for  the  Company.  Through  the  Board  of  Directors’  oversight  role  and  review  of 
management’s active role, the directors satisfy themselves that the risk management processes designed and 
implemented by management (as more particularly described below) are adapted to and integrated with the 
Company’s corporate strategy, are functioning as designed and that steps are taken to foster a culture in which 
each  employee  understands  his  or  her  impact  on  the  assessment  and  management  of  risk,  his  or  her 
responsibility for acting within appropriate limits, and his or her ultimate accountability. 

The Company has an enterprise risk management process and framework, which includes an Executive Risk 
Management Committee and a risk committee working group. The Executive Risk Management Committee is 
composed of members of senior management, including our Chief Executive Officer and other members of 
management  in  key  functions  and  selected  divisions  of  the  Company.  The  duties  of  the  Executive  Risk 
Management Committee include the following: reviewing and approving appropriate changes to the Company’s 
policies  and  procedures  regarding  risk  management;  identifying  and  assessing  operational,  commercial, 
strategic,  financial,  macroeconomic  and  geopolitical  risks  facing  the  Company;  identifying  risks  and  taking 
corrective actions, if appropriate; monitoring key indicators to assess the effectiveness and adequacy of the 
Company’s risk management activities; and communicating with the Board of Directors at least once a year 
with  respect  to  risk  management.  The  Executive  Risk  Management  Committee  and/or  members  of 
management present a report on risk management activities to the Board of Directors at least annually. The 
risk committee working group identifies risks facing the Company, makes an assessment of each risk, identifies 
preventive  and  mitigating  controls  and  then  makes  recommendations  for  improvement  opportunities  to  the 
Board of Directors or our Chief Executive Officer, as appropriate. 

Compensation  and  Risk.  We  regularly  assess  risks  related  to  our  compensation  programs,  including  our 
executive compensation programs, and do not believe that the risks arising from our compensation policies and 
practices  are  reasonably  likely  to  have  a  material  adverse  effect  on  the  Company.  The  Compensation 
Committee  reviews  information  and  solicits  input  from  an  independent  compensation  consultant  regarding 
compensation  factors,  which  could  mitigate  or  encourage  excessive  risk-taking.  In  its  review  in  2018,  the 
Compensation Committee considered the attributes of our programs, including the metrics used to determine 
incentive  awards,  the  weight  of  each  metric,  the  timing  and  processes  for  setting  performance  targets  and 
validating  results,  the  performance  measurement  periods  and  time  horizons,  the  total  mix  of  pay  and  the 
maximum compensation and incentive award payout opportunities. 

Independence of Board Members. Our Corporate Governance Guidelines require that at least a majority of the 
members of the Board of Directors meet the independence standards set by the NYSE. In order to meet the 
NYSE’s independence standards, a member of the Board of Directors must not have a relationship with the 
Company  that  falls  within  certain  objective  categories  established  by  the  NYSE.  In  addition,  the  Board  of 
Directors must then affirmatively determine, with respect to each director and nominee, that he or she did not 
otherwise have a material relationship with the Company. There is no family relationship between any of our 
directors. 

The Board of Directors has determined that its current members, with the exception of Jeremy D. Thigpen (the 
Company’s President and Chief Executive Officer), are independent and meet the applicable independence 
standards set by the NYSE, the SEC and our guidelines. Additionally, our Compensation, Audit and Corporate 
Governance  Committees  are  composed  solely  of  directors  who  meet  the  applicable  NYSE  and  SEC 
independence standards.   

In making its independence determinations, the Board of Directors considered the fact that certain directors, as 
described below, are or within the past three years have been directors or officers of companies with which we 
conduct business in the ordinary course. After evaluating these relationships in light of applicable SEC and 
NYSE  standards,  the  Board  of  Directors  concluded  that  they  have  no  effect  on  the  independence  of  these 
directors.   

The Board of Directors also considered the below transactions and believes they were on arm’s-length terms 
that  were  reasonable  and  competitive.  Accordingly,  the  Board  of  Directors  concluded  that  the  relationships 
described below have no effect on the independence of these directors. Because of our extensive operations, 
transactions and director relationships, transactions of this nature are expected to take place in the ordinary 
course of business in the future.

●  Since 2012, Mr. Barker has served as a non-executive director and as a member of the audit committee 

of Aviva plc, a company that provides insurance-related services to the Company. 

●  Mr. Barker’s son was a Transaction Services strategy consultant at PwC UK, an assurance, advisory 
and  tax  services  firm  that  provides  services  to  the  Company,  but  is  not  the  Company’s  independent 
registered public accounting firm. Although Mr. Barker’s son was employed by PwC until January 2019, 
his son did not, directly or indirectly, provide any services to the Company or any of its affiliates, and his 
son  worked  within  a  division  of  PwC  that  did  not  provide  any  services  to  the  Company  or  any  of  its 
affiliates. Moreover, Mr. Barker’s son was not a partner or principal of PwC, but was instead one of more 
than  250,000  persons  employed  by  PwC  worldwide.  Further,  the  Company’s  relationship  with  PwC 
predates both the Company’s relationship with Mr. Barker and PwC’s relationship with Mr. Barker’s son. 

●  Mr. Curado’s son began working in GE’s corporate audit department in 2017 and his son-in-law works 
as an engineer for Mitsubishi Industries, both of which provide services or products to the Company. 

●  Since 2010, Mr. Deaton has served as a non-executive director of Air Products and Chemicals, Inc., from 

which the Company rented and purchased rig-related products and equipment. 

●  From 2016 to 2018, Mr. Merksamer served as non-executive director of American International Group, 

Inc., a company that provides insurance-related services to the Company. 

●  Since 2010, Mr. Tan has served as a non-executive director of Keppel Corporation, which provides the 

Company with services related to rig construction and shipyard work. 

●  Upon and following the closing of the Company’s acquisition of Songa Offshore in January 2018, Mr. 
Mohn  became  the  beneficial  owner  of  approximately  67,740,289  Company  shares,  consisting  of 
31,120,553 Company shares issued in connection with the acquisition, an additional 2,000,000 shares 
purchased on the open market on or before March 12, 2018, and 34,619,736 Company shares that may 
be  issued  in  the  future  upon  exchange  of  the  0.5%  Exchangeable  Senior  Bonds  due  2023  issued  in 
connection  with  the  acquisition.  As  a  result,  assuming  the  conversion  of  the  Exchangeable  Bonds 
beneficially owned by Mr. Mohn, he will possess voting rights with respect to approximately 10.50% of 
the Company’s outstanding shares as of March 1, 2019. The Board of Directors evaluated Mr. Mohn’s 
overall beneficial ownership of Company shares and concluded that his ownership of Company shares 
is not a material relationship that would affect his independence or service as a director of the Company, 
and that he meets the standards for independence adopted by the SEC and the NYSE. 

Executive Sessions. Our independent directors met in executive session without management at each of the 
regularly  scheduled  Board  of  Directors’  meetings  held  in  2018.  During  2019,  the  independent  directors  are 
again scheduled to meet in executive session at each regularly scheduled Board of Directors’ meeting. The 
independent directors generally designate the Chairman of the Board of Directors to act as the presiding director 
for executive sessions. 

Director Nomination Process. The Board of Directors has designated the Corporate Governance Committee as 
the  committee  authorized  to  consider  and  recommend  nominees  for  the  Board  of  Directors.  The  Board  of 
Directors  believes  that  all  members  of  the  Corporate  Governance  Committee  meet  the  applicable  NYSE 
independence requirements. 

Our Corporate Governance Guidelines provide that the Corporate Governance Committee should periodically 
assess the needs of the Company and the Board of Directors, so as to recommend candidates who will further 

P-40   Transocean 2019 Proxy Statement 

 
 
 
 
 
CORPORATE GOVERNANCE 

our  goals.  In  making  that  assessment,  the  Corporate  Governance  Committee  has  determined  that  a 
recommended nominee must have the following minimum qualifications: 

●  High professional and personal ethics and values 

●  A record of professional accomplishment in his/her chosen field 

●  Relevant expertise and experience 

●  A reputation, both personal and professional, consistent with our FIRST Shared Values 

In addition to these minimum qualifications, the Corporate Governance Committee considers other qualities in 
nominees  that  may  be  desirable.  In  particular,  the  Board  of  Directors  is  committed  to  having  a  majority  of 
independent directors  and,  accordingly,  the  Corporate  Governance  Committee  evaluates  the  independence 
status of any potential director. The Corporate Governance Committee evaluates whether or not a candidate 
contributes to the Board of Directors’ overall diversity, the candidate’s contribution to Board’s existing chemistry 
and  collaborative  culture,  and  whether or  not  the  candidate can contribute  positively  to  the  Board’s  diverse 
expertise in environmental, health, safety, industry, market and financial matters. The Corporate Governance 
Committee also considers whether or not the candidate may have professional or personal experiences and 
expertise  relevant  to  our  business  (such  as  expertise  in  the  industry  and  in  critical  health,  safety  and 
environmental  matters)  and  the  Company’s  position as  the  leading  international  provider  of  offshore  drilling 
services. 

As described above, in accordance with the majority vote provisions of our Corporate Governance Guidelines, 
the Board of Directors 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 
more votes cast “FOR” than “AGAINST” his or her election in an uncontested election and (2) the Board of 
Directors  accepts  the  resignation.  The  Board  of  Directors  will  also  request  a  statement  from  any  person 
nominated as a director by anyone other than the Board of Directors as to whether that person will also submit 
an irrevocable letter of resignation upon the same terms as a person nominated by the Board of Directors. For 
purposes of our Corporate Governance Guidelines, an uncontested election occurs in an election of directors 
that does not constitute a contested election, and a contested election occurs when (i) the Secretary of the 
Company receives a notice that a shareholder has nominated a person for election to the Board of Directors in 
compliance with the advance notice requirements for shareholder nominees for director set forth in our Articles 
of Association and (ii) such nomination has not been withdrawn by such shareholder on or prior to the day next 
preceding the date the Company first mails its notice of meeting for such meeting to the shareholders. 

The Corporate Governance Committee has several methods of identifying Board of Directors candidates. First, 
the  Corporate  Governance  Committee  considers  and  evaluates  annually  whether  each  director  nominee  is 
qualified to be nominated for election or reelection to the Board of Directors. Second, the Corporate Governance 
Committee  requests  from  time  to  time  that  its  members  and  the  other  Board  members  identify  possible 
candidates  for  any  vacancies  or  potential  vacancies.  Third,  the  Corporate  Governance  Committee  has  the 
authority to retain one or more executive search firms to aid in its search. Each executive search firm assists 
the Corporate Governance Committee in identifying potential Board of Directors candidates, interviewing those 
candidates and conducting investigations relative to their background and qualifications.

CORPORATE GOVERNANCE 

The  Corporate  Governance  Committee  considers  nominees  for  director  who  are  recommended  by  our 
shareholders. Recommendations may be submitted in writing, along with: 

●  The name of and contact information for the candidate; 

●  A statement detailing the candidate’s qualifications and business and educational experience; 

● 

Information  regarding  the  qualifications  and  qualities  described  under  “Director  Nomination  Process” 
above; 

●  A signed statement of the proposed candidate consenting to be named as a candidate and, if nominated 

and elected, to serve as a director; 

●  A  signed  irrevocable  letter  of  resignation  from  the  proposed  candidate  that,  in  accordance  with  our 
Corporate  Governance  Guidelines,  would  be  effective  upon  and  only  in  the  event  that  (1)  in  an 
uncontested election, such candidate fails to receive more votes cast “FOR” than “AGAINST” his or her 
election and (2) the Board of Directors accepts the resignation; 

●  A statement that the writer is a shareholder and is proposing a candidate for consideration by the 

Corporate Governance Committee; 

●  A statement detailing any relationship between the candidate and any customer, supplier or competitor 

of ours; 

●  Financial and accounting experience of the candidate, to enable the Corporate Governance Committee 

to determine whether the candidate would be suitable for Audit Committee membership; and 

●  Detailed information about any relationship or understanding between the proposing shareholder and 

the candidate. 

Shareholders may submit nominations to our Corporate Secretary, Transocean Ltd., Turmstrasse 30, CH-6312 
Steinhausen,  Switzerland.  Unsolicited  recommendations  must  contain  all  of  the  information  that  would  be 
required in a proxy statement soliciting proxies for the election of the candidate as a director. The extent to 
which the Corporate Governance Committee dedicates time and resources to the consideration and evaluation 
of  any  potential  nominee  brought  to  its  attention  depends  on  the  information  available  to  the  Corporate 
Governance Committee about the qualifications and suitability of the individual, viewed in light of the needs of 
the Board of Directors, and is at the Corporate Governance Committee’s discretion. The Corporate Governance 
Committee evaluates the desirability for incumbent directors to continue on the Board of Directors following the 
expiration of their respective terms, taking into account their contributions as Board members and the benefit 
that results from the increasing insight and experience developed over a period of time. Although the Corporate 
Governance Committee will consider candidates for director recommended by shareholders, it may determine 
not to recommend that the Board of Directors, and the Board of Directors may determine not to, nominate those 
candidates for election to the Board of Directors. 

In addition to recommending director nominees to the Corporate Governance Committee, any shareholder may, 
in compliance with applicable requirements, nominate directors for election at annual general meetings of the 
shareholders. For more information on this topic, see “Other Matters.” 

Executive  and  Director  Compensation  Process.  Our  Compensation  Committee  has  established  an  annual 
process for reviewing and establishing executive compensation levels. An outside consultant, Pay Governance 
LLC,  retained  by  the  Compensation  Committee  has  provided  the  Compensation  Committee  with  relevant 
market  data  and  alternatives  to  consider  in  determining  appropriate  compensation  levels  for  each  of  our 
executive officers. Pay Governance has served as the Compensation Committee’s outside consultant since 
February 2011.  Our  Chief  Executive  Officer  also  assists  the  Compensation  Committee  in  the  executive 
compensation setting process. For a more thorough discussion of the roles, responsibilities and process we 
use for setting executive compensation, see “Compensation Discussion and Analysis.” 

Director  compensation  is  set  by  the  Board  of  Directors  upon  a  recommendation  from  the  Compensation 
Committee. Since 2015, director compensation is also subject to shareholder approval at the Company’s annual 
general meetings. Each calendar year, the Compensation Committee reviews the compensation paid to our 

P-42   Transocean 2019 Proxy Statement 

 
 
 
 
CORPORATE GOVERNANCE 

directors to be certain that it is competitive in attracting and retaining qualified directors. The Compensation 
Committee  has  used  its  outside  consultant,  Pay  Governance  LLC,  to  gather  data  regarding  director 
compensation at (1) certain similar size companies in the general industry, as well as (2) the same peer group 
of  companies  generally  utilized  in  the  consideration  of  executive  compensation,  as  set  forth  in  the 
“Compensation  Discussion  and  Analysis.”  Based  upon  its  review  of  the  data  and  its  own  judgment,  the 
Compensation Committee develops a recommendation for consideration by the Board of Directors. If serving 
as director on the Board of Directors, our Chief Executive Officer receives no additional compensation for such 
service. 

Process for Communication by Shareholders and Interested Parties with the Board of Directors. The Board of 
Directors has established a process whereby interested parties may communicate with the Board of Directors 
and/or  with  any  individual  director.  Interested  parties,  including  shareholders,  may  send  communications  in 
writing, addressed to the Board of Directors or an individual director, c/o the Corporate Secretary, Transocean 
Ltd.,  Turmstrasse  30,  CH-6312  Steinhausen,  Switzerland.  The  Corporate  Secretary  will  forward  these 
communications, as appropriate, to the addressee depending on the facts and circumstances outlined in the 
communication. The Board of Directors has directed the Corporate Secretary not to forward certain items, such 
as:  spam,  junk  mailings,  product  inquiries,  resumes  and  other  forms  of  job  inquiries,  surveys  and  business 
solicitations. Additionally, the Board of Directors has advised the Corporate Secretary not to forward material 
that is illegal or threatening, but to make the Board of Directors aware of such material, and may request it be 
forwarded, retained or destroyed at the Board of Directors’ discretion. 

Policies  and  Procedures  for  Approval  of  Transactions  with  Related  Persons.  The  Board  of  Directors  has  a 
written policy with respect to related person transactions pursuant to which such transactions are reviewed, 
approved or ratified. The policy applies to any transaction in which (1) the Company is a participant, (2) any 
related person has a direct or indirect material interest and (3) the amount involved exceeds U.S. $120,000, 
but excludes any transaction that does not require disclosure under Item 404(a) of Regulation S-K. The Audit 
Committee,  with  assistance  from  the  Company’s  General  Counsel,  is  responsible  for  reviewing,  approving 
and/or ratifying any related person transaction. 

To  identify  related  person  transactions,  each  year  we  distribute  and  require  our  directors  and  officers  to 
complete questionnaires identifying transactions with us in which the officer or director or their immediate family 
members have an interest. Quarterly, our directors and officers must re-affirm in writing that the information 
previously provided in their questionnaires remains accurate and complete, and provide updates regarding any 
related  person  relationships  that  may  have  arisen.  Our  Code  of  Integrity  further  requires  that  an  executive 
officer inform the Company when the executive officer’s private interest interferes or appears to interfere in any 
way  with  our  interests.  In  addition,  the Board  of  Directors’  Corporate  Governance  Guidelines  require  that  a 
director must immediately inform the Board of Directors or the Chairman of the Board of Directors in the event 
that a director believes he or she has an actual or potential conflict with our interests. Furthermore, under our 
Organizational Regulations, a director must disclose and abstain from voting with respect to matters that feature 
unresolved conflicts of interest. 

Under  our  related  persons  transaction  policy,  the  Audit  Committee  considers  all  relevant  facts  and 
circumstances available, including the related persons involved, their relationship to the Company, their interest 
and  role  in  the  transaction,  the  proposed  terms of  the  transaction  (including expected  aggregate  value  and 
value to be derived by the related person), the benefits to the Company, the availability to the Company of 
alternative means or transactions to obtain like benefits and the terms that would prevail in a similar transaction 
with an unaffiliated third party. For related person transactions that do not receive prior approval from the Audit 
Committee,  the  transactions  are  submitted  to  the  Audit  Committee  to  consider  all  relevant  facts  and 
circumstances  and,  based  on  its  conclusions,  evaluate  all  options,  including,  but  not  limited  to,  ratification, 
amendment  or  termination  of  the  transaction.  Since  the  beginning  of  2018,  there  were  no  related  person 
transactions where such policies and procedures were not followed. 

Certain Relationships and Related Party Transactions. From 2014 to 2017, Mr. Miller served as the Executive 
Chairman of NOW Inc. (NYSE: DNOW). We regularly procure equipment and services from NOW Inc., at arm’s 
length  terms  and  within  the  ordinary  course  of  business.  In  2018,  our  purchasing  activity  with  NOW  Inc. 
represented less than 2% of that company’s reported gross revenue for such period.

In  connection  with  our  acquisition  of  Songa  Offshore,  Mr.  Mohn  acquired  beneficial  ownership  of  U.S. 
$355,813,000 aggregate principal amount of Transocean Inc.’s 0.5% Exchangeable Senior Bonds due 2023, 
including exchangeable bonds acquired by Perestroika AS (an entity affiliated with Mr. Mohn) as part of our 
private  exchange  offers  undertaken  to  refinance  certain  of  Songa  Offshore’s  previously  outstanding 
indebtedness. These exchangeable bonds bear interest at an annual rate of 0.5%, payable semiannually, and 
are exchangeable into shares of Transocean Ltd. at any time at the option of the holder. In connection with our 
acquisition of Songa Offshore, we also entered into a registration rights agreement with certain affiliates of Asia 
Research & Capital Management and Perestroika AS, each of whom is one of our significant shareholders. 
This  registration  rights  agreement  provides  them  with  certain  customary  registration  rights  over  the 
exchangeable bonds they received as part of our private exchange offers undertaken to refinance certain of 
Songa  Offshore’s  previously  outstanding  indebtedness  and,  in  the  case  of  Perestroika  AS,  any  shares  and 
exchangeable bonds that Perestroika AS received in the acquisition as a former shareholder of Songa Offshore 
or that it may acquire in the future. 

Director  Attendance  at  Annual  General  Meeting.  We  expect  all  of  our  directors  to  attend  the  2019  Annual 
General Meeting. At the 2018 Annual General Meeting, all directors were in attendance.

Board Meetings and Committees 

During 2018, the Board of Directors of Transocean Ltd. held four meetings. The Board of Directors and the 
committees of the Board of Directors met at least once a quarter and the quarterly meetings generally occurred 
over a period of two days. Each of our directors attended 100% of the meetings following their election, including 
meetings of committees on which the director served. 

The Board of Directors has standing Audit, Compensation, Finance, Corporate Governance, and Health, Safety 
and Environment Committees. As noted above, the charters for these committees may be found on our website 
at: www.deepwater.com by selecting the Governance page in the Investors section dropdown. In addition, the 
Board  of  Directors  may  from  time  to  time  form  special  committees  to consider  particular  matters  that  arise. 
Following the 2019 Annual General Meeting, the Board expects to complete its annual review of committee 
assignments.     

Compensation Committee. The purpose of the Compensation Committee is to assist the Board of Directors in 
(1) developing an appropriate compensation program and benefit package for (a) members of the Executive 
Management  Team  (as  defined  below),  (b)  persons  defined  as  “officers”  pursuant  to  section  16(a)  of  the 
Exchange  Act,  and  (c)  any  other  person  whose  compensation  is  required  to  be  disclosed  by  applicable 
securities laws and regulations (collectively, the “Specified Executives”) and members of the Board of Directors; 
and  (2)  complying  with  the  Board  of  Directors’  legal  and  regulatory  requirements  as  to  Board  member  and 
Specified Executives compensation in order to facilitate the Company’s ability to attract, retain and motivate

qualified  individuals  in  a  system  that  aligns  compensation  with  the  Company’s  business  performance.  The 
authority and responsibilities of the Compensation Committee include, among others, the following: 

●  Annually  review  and  recommend  to  the  Board  of  Directors  for  submission  to  and  ratification  by  the 
shareholders pursuant to Swiss law and our Articles of Association the maximum aggregate amount of 
compensation of the Board of Directors and the Executive Management Team for the period between 
the Annual General Meeting at which ratification is sought and the next Annual General Meeting; 

●  Annually review and recommend to the Board for submission to and ratification by the shareholders the 
maximum aggregate amount of compensation of the Specified Executives and each member of the 
Board for the fiscal year commencing after the Annual General Meeting at which ratification is sought; 

●  Select  appropriate  peer  groups  and  market  reference  points  against  which  the  Company’s  Board  of 

Directors and executive compensation is compared; 

●  Annually recommend focus areas for our Chief Executive Officer for approval by members of our Board 

of Directors who meet our independence and experience requirements; 

●  Annually  review,  with  participation  of  our  full  Board  of  Directors,  our  Chief  Executive  Officer’s 

performance in light of our established focus areas; 

●  Annually set our Chief Executive Officer’s compensation based, as appropriate, upon his performance 
evaluation together with competitive data and subject to shareholder ratification requirements pursuant 
to our Articles of Association and applicable law; 

●  Administer  our  long-term  incentive  plans,  Performance  Award  and  Cash  Bonus  Plan,  Deferred 
Compensation Plan, and any other compensation plans or arrangements providing for benefits primarily 
to members of the Board of Directors and executive officers in accordance with goals and objectives 
established by the Board of Directors, the terms of the plans, and any applicable rules and regulations; 

●  Consider  and  make  recommendations  to  the  Board  of  Directors,  with  guidance  from  an  outside 
compensation  consultant,  concerning  the  existing  Board  of  Directors  and  executive  compensation 
programs and changes to such programs; 

●  Consider, with guidance from an outside compensation consultant, and approve the material terms of 
any  employment,  severance,  termination  or  other  similar  arrangements  (to  the  extent  permitted  by 
applicable law and our Articles of Association) that may be entered into with members of the Board of 
Directors  and  Specified  Executives;  provided,  however,  that  the  Compensation  Committee  shall  not 
recommend and the Board of Directors shall not authorize “single-trigger” change of control agreements 
for any of our officers or directors; 

●  Assess  the  risks,  with  the  assistance  of  external  resources  as  the  Compensation  Committee  deems 
appropriate,  of  the  Company’s  compensation  arrangements  applicable  to  members  of  the  Board  of 
Directors and the Specified Executives; and 

●  Retain  and  approve  the  fees  of  legal,  accounting  or  other  advisors,  including  any  compensation 
consultant,  employed  by  the  Committee  to  assist  it  in  the  evaluation  of  executive  and  director 
compensation. 

See  “Compensation  Discussion  and  Analysis”  for  a  discussion  of  additional  responsibilities  of  the 
Compensation Committee. 

The  Compensation  Committee  may  delegate  specific  responsibilities  to  one  or  more  individual  committee 
members to the extent permitted by law, NYSE listing standards and the Compensation Committee’s governing 
documents. The Compensation Committee may delegate all or a portion of its powers and responsibilities with 
respect to the compensation plans and programs described above and in our “Compensation Discussion and 
Analysis” to one or more of our management committees; provided, that the Compensation Committee retains 
all power and responsibility with respect to awards granted to our Board members and executive officers. The 
Chief Executive Officer has been delegated authority to grant equity awards under the Company’s long-term 
incentive plans to new and existing employees of the Company, excluding executive officers and other officers

above the Vice President level, provided that such awards shall not exceed U.S. $5,000,000 in grant value per 
calendar year in aggregate and no such individual award shall exceed U.S. $350,000 in grant value. 

The Compensation Committee has delegated to a subcommittee composed of its chairman and at least one 
additional committee member the authority to approve interim compensation actions resulting from promotions, 
competitive realignment, or the hiring of new executive officers (excluding the Chief Executive Officer), including 
but not limited to establishing annual base salary, annual bonus targets, long-term bonus targets and the grant 
of equity awards, subject to any required vote of the shareholders. The Compensation Committee has also 
delegated  authority  to  the  Chief  Executive  Officer  to,  upon  termination  of  service  of  an  employee  of  the 
Company  (excluding  executive  officers  and  other  officers  at  or  above  the  Senior  Vice  President  level), 
accelerate  vesting  of  awards  granted  under  the  Company’s  long-term  incentive  plans  and  to  extend 
exercisability  of  options  for  a  period  of  up  to  one year,  but  not  beyond  the  original  exercise  period.  The 
Compensation Committee has further delegated authority to the Chief Executive Officer to determine whether 
an  individual  is  disabled  and/or  to  set  applicable  criteria  for  making  such  determination  for  purposes  of  the 
Company’s long-term incentives plans. The Compensation Committee is notified of compensation actions made 
by the Chief Executive Officer or the subcommittee at the meeting following the end of each calendar quarter 
in which such actions are taken. 

The current members of the Compensation Committee are Mr. Tan, Chairman, and Messrs. Curado and Intrieri. 
The Compensation Committee met four times during 2018. 

Finance Committee. The Finance Committee approves our long-term financial policies, insurance programs 
and investment policies. It also makes recommendations to the Board of Directors concerning the Company’s 
dividend policy, securities repurchase actions, the issuance and terms of debt and equity securities and the 
establishment of bank lines of credit. In addition, the Finance Committee approves the creation, termination 
and  amendment  of  certain  of  our  employee  benefit  programs  and  periodically  reviews  the  status  of  these 
programs and the performance of the managers of the funded programs. 

The current members of the Finance Committee are Mr. Muller, Chairman, and Messrs. Barker, Intrieri and 
Merksamer. The Finance Committee met five times during 2018. 

Corporate  Governance  Committee.  The  Corporate  Governance  Committee  makes  recommendations  to  the 
Board of Directors with respect to the nomination of candidates for election to the Board of Directors, how the 
Board  of  Directors  should  function  and  how  the  Board  of  Directors  should  interact  with  shareholders  and 
management.  It  also  develops  and  recommends  to  the  Board  a  set  of  corporate  governance  principles 
applicable to the Company, coordinates the self-evaluation of the Board of Directors and its committees, and 
reviews the qualifications of and proposes to the Board of Directors candidates to stand for election at the next 
general meeting of shareholders. 

The current members of the Corporate Governance Committee are Mr. Intrieri, Chairman, Ms. Chang and Mr. 
Deaton. The Corporate Governance Committee met four times during 2018. 

Health, Safety and Environment Committee. The Health, Safety and Environment Committee assists the Board 
of Directors in fulfilling its responsibilities to oversee the Company’s management of risk in the areas of health, 
safety  and  the  environment.  The  Health,  Safety  and  Environment  Committee  reviews  and  discusses  with 
management the status of key environmental, health and safety issues. Additionally, the Health, Safety and 
Environment Committee regularly evaluates Company policies, practices and performance related to health, 
safety and environmental issues and guides strategy decisions to promote company goals and compliance with 
applicable  rules  and  regulations.  From  2013  to  February  13,  2019,  the  Health,  Safety  and  Environment 
Committee assumed additional responsibility to oversee the Company’s implementation of certain requirements 
of the Consent Decree by and among the U.S. Department of Justice and certain of the Company’s affiliates. 
The Consent Decree was terminated on February 13, 2019. Accordingly, the Consent Decree has no further 
force or effect on the Company. 

The  current  members  of  the  Health,  Safety  and  Environment  Committee  are  Mr.  Deaton,  Chairman,  and 
Messrs. Merksamer, Mohn, Muller and Tan. The Health, Safety and Environment Committee met four times

BOARD MEETINGS AND COMMITTEES 

Audit  Committee.  The  Audit  Committee  is  responsible  for  recommending  the  selection,  retention  and 
termination of our independent registered public accountants and our auditor pursuant to the Swiss Code of 
Obligations  to  the  Board  of  Directors  and  to  our  shareholders  for  their  approval  at  a  general  meeting  of 
shareholders.  The  Audit  Committee  is  directly  responsible  for  the  compensation  and  oversight  of  our 
independent  registered  public  accountants  and  our  auditor  pursuant  to  the  Swiss  Code  of  Obligations.  The 
Audit Committee further advises as necessary in the selection of the lead audit partner. The Audit Committee 
also monitors the integrity of our financial statements and the independence and performance of our auditors 
and their lead audit partner and reviews our financial reporting processes. The Audit Committee reviews and 
reports to the Board of Directors the scope and results of audits by our independent registered public accounting 
firm, our auditor pursuant to the Swiss Code of Obligations and our internal auditing staff and reviews the audit 
and other professional services rendered by the accounting firm. It also reviews with the accounting firm the 
adequacy of our system of internal controls. It reviews transactions between us and our directors and officers 
for  disclosure  in  the  proxy  statement,  our  policies  regarding  those  transactions  and  compliance  with  our 
business ethics and conflict of interest policies. 

The Board of Directors requires that all members of the Audit Committee meet the financial literacy standard 
required under the NYSE rules and that at least one member qualifies as having accounting or related financial 
management expertise under the NYSE rules. In addition, the SEC has adopted rules requiring that we disclose 
whether or not the Audit Committee has an “audit committee financial expert” as a member. An “audit committee 
financial expert” is defined as a person who, based on his or her experience, possesses all of the following 
attributes: 

●  An understanding of generally accepted accounting principles and financial statements; 

●  The  ability  to  assess  the  general  application  of  such  principles  in  connection  with  the  accounting  for 

estimates, accruals, and reserves; 

●  Experience preparing, auditing, analyzing or evaluating financial statements that present a breadth of 
complexity of accounting issues that are generally comparable to the breadth and level of complexity of 
issues that can reasonably be expected to be raised by our financial statements, or experience actively 
supervising one or more persons engaged in such activities; 

●  An understanding of internal control over financial reporting; and 

●  An understanding of audit committee functions. 

The person must have acquired such attributes through one or more of the following: 

●  Education and experience as a principal financial officer, principal accounting officer, controller, public 
accountant  or  auditor  or  experience  in  one  or  more  positions  that  involve  the  performance  of  similar 
functions; 

●  Experience actively supervising a principal financial officer, principal accounting officer, controller, public 

accountant, auditor or person performing similar functions; 

●  Experience overseeing or assessing the performance of companies or public accountants with respect 

to the preparation, auditing or evaluation of financial statements; or 

●  Other relevant experience. 

The current members of the Audit Committee are Mr. Barker, Chairman, Ms. Chang, and Messrs. Curado and 
Mohn. The Audit Committee met eight times during 2018. 

The Board of Directors has reviewed the criteria set by the NYSE and SEC and determined that each of the 
current members of the Audit Committee is “financially literate” and qualifies as an “audit committee financial 
expert.”  In  addition,  the  Board  of  Directors  has  determined  that  all  of  the  current  members  of  the  Audit 
Committee  qualify  under  NYSE  rules as  having  accounting  or  related  financial  management  expertise.

BOARD MEETINGS AND COMMITTEES 

Mr. Barker is a chartered accountant, served as an audit partner in an accounting firm and served as the Vice 
Chairman-U.K.  of  PricewaterhouseCoopers  LLP  from  2008  to  2011.  Ms. Chang  was  previously  partner  in 
charge of Corporate Finance for KPMG Peat Marwick LLP. Mr. Curado is the Chief Executive Officer of Ultrapar 
S.A.  and  he  has  significant  risk  management  and  compliance  experience.  Mr.  Mohn  is  the  sole  owner  and 
managing director of Perestroika, a Norwegian investment company, and served previously as a director of 
Songa Offshore SE, Chairman of the Songa Board and as managing director of Frank Mohn AS. 

In addition to Ms. Chang’s membership on the Audit Committee, she also serves on the audit committees of 
Sykes  Enterprises,  Incorporated,  Edison  International  and  certain  funds  advised  by  the  Capital  Group  of 
Companies, Inc. and its subsidiaries. Pursuant to NYSE rules, the Board of Directors has determined that Ms. 
Chang’s service on the audit committees of such companies would not impair her ability to effectively serve on 
the Company’s Audit Committee. 

Finally,  NYSE  rules restrict  directors  who  have  relationships  with  the  Company  that  may  interfere  with  the 
exercise of their independence from management and the Company from serving on the Audit Committee. We 
believe that the members of the Audit Committee have no such relationships and are therefore independent for 
purposes of NYSE rules. 

Director Compensation Strategy 

Directors who are employees of the Company do not receive compensation for Board of Directors’ service. At 
present, all of the directors except Mr. Thigpen, our President and Chief Executive Officer, are non-employees 
and receive compensation for their service on the Board of Directors. 

We use a combination of cash and equity compensation to attract and retain qualified candidates to serve on 
the Board of Directors. The Board of Directors believes that any compensation method should be weighted 
more  toward  compensation  in  the  form  of  equity  in  order  to  more  closely  align  director  compensation  with 
shareholders’ interests. 

In 2018, non-employee director compensation in U.S. dollars included the following fixed components: 

Annual Retainer—non-employee Director 
Annual Retainer—non-employee Vice Chairman(1) 
Annual Retainer—non-employee Chairman 
Additional Annual Retainer for Committee Chairmen   

Audit Committee 
Compensation Committee 
Corporate Governance Committee, Finance Committee and Health,

(1)    Currently, the Company does not have any director serving in a Vice Chairman role. 
(2)    Restricted share units are granted to each non-employee director and chairman annually and have an
aggregate value equal to U.S. $210,000 and U.S. $325,000 respectively, based upon the average of
the high and low sales prices of our shares for each of the 10 trading days immediately prior to the date
of grant. The restricted share units vest on the date first to occur of (1) the first anniversary of the date
of grant or (2) the Annual General Meeting next following the date of grant, subject to continued service
through  the  vesting  date.  Vesting  of  the  restricted  share  units  is  not  subject  to  any  performance
measures. 

In addition, we pay or reimburse our directors’ travel and incidental expenses incurred for attending Board of 
Directors, committee and shareholder meetings and for other Company business-related purposes.

2018 DIRECTOR COMPENSATION 

In 2018, each non-employee member of the Board of Directors received the compensation described above. 

At the Board of Directors meeting held immediately after the 2018 Annual General Meeting of our shareholders, 
the  Board  of  Directors  granted  16,141  restricted  share  units  to  each  non-employee  director  (other  than  the 
Chairman) and 24,981 restricted share units to the non-employee Chairman in aggregate value equal to U.S. 
$210,000 and U.S. $325,000, respectively, based upon the average of the high and low sales prices of our 
shares for the 10 trading days immediately prior to the date of grant (calculated at U.S. $13.01 per share). Each 
non-employee director is required to acquire and retain a number of our shares and/or restricted share units at 
least equal in value to an amount five times the annual director retainer. Each non-employee director’s vested 
restricted share units generally are not settled until the non-employee director’s service with the Company ends. 

The following summarizes the compensation of our non-employee directors for 2018.

AUDIT COMMITTEE REPORT 

The Audit Committee, consisting of four independent directors, operates under the Audit Committee Charter as 
adopted by the Board, in overseeing: 

●  The integrity of the financial reporting process resulting in the Company’s financial statements; 

●  Compliance with legal and regulatory requirements; 

●  The  independence,  qualifications  and  performance  of  the  Company’s  independent  registered 

accountants, Ernst & Young LLP (“EY”); and 

●  The performance of the internal audit function. 

The Committee complied in 2018 with all of the requirements described in its Charter, which is available on the 
Governance page of the Company’s website: www.deepwater.com. 

The Board has determined that all the members of the Committee are independent, in accordance with the 
SEC definition, are financially literate and qualify as Audit Committee Financial Experts, as defined by SEC 
rules. 

Management is responsible for the Company’s disclosure controls and procedures, internal controls and the 
financial reporting process, including the integrity and objectivity of the financial statements. The Committee: 

●  Reviewed  the  Company’s  financial  statements  and  financial  reporting  processes,  including  internal 

controls over financial reporting; 

●  Reviewed  and  discussed  with  EY  and  management  the  Company’s  audited  financial  statements 

included in the Annual Report; 

●  Discussed  various  matters  with  EY,  including  matters  required  by  the  Public  Company  Accounting 

Oversight Board’s (“PCAOB”) “Communications with Audit Committees”; 

●  Reviewed and discussed with EY its report on internal control over financial reporting; 
●  Oversaw the Company’s internal audit function, including the performance of the Chief Audit Executive, 

internal audit plan, budget, resources and staffing; 

●  Oversaw the Company’s Legal, Compliance and Ethics program, including helpline calls and 

investigations, and employee code of integrity; and 

●  Recommended to the Company’s Board of Directors that the Company’s audited financial statements 
for the year ended December 31, 2018, be included in the annual report on Form 10-K filing with the 
SEC. 

The Committee is responsible for the appointment, compensation and oversight of the independent registered 
accountant in accordance with SEC, PCAOB and the Swiss Code of Obligations. The Committee considered 
several factors in determining whether to reappoint EY as the Company’s independent registered accountant, 
such as: 

●  Qualifications including industry expertise, knowledge of the Company’s processes, and experience of 

the audit team; 

● 
● 

Performance including quality of communication, professional skepticism; 

Independence;

AUDIT COMMITTEE REPORT 

Length of service, which began in 1999; 

● 
●  Results from PCAOB inspections; and 
● 

EY’s internal quality control and tone at the top. 

The Committee approves annually the scope, plans and fees for the annual audit, taking into consideration 
several  factors  including  a  breakdown  of  the  services  to  be  provided,  proposed  staffing,  changes  in  the 
Company  and  industry  from  the  prior  year.  The  fee  approval  process  balances  the  audit  scope  and  hours 
required for a high-quality audit and driving efficiencies from both the Company and EY while compensating 
EY fairly. The Audit Committee pre-approved all audit related and non-audit related services. 

Agendas for Audit Committee meetings are developed with input from the Committee, management, the Chief 
Audit Executive and EY. The Committee met eight times in 2018 with regular executive sessions with EY and 
management, including the Chief Audit Executive.

COMPENSATION DISCUSSION AND ANALYSIS 

2018 Business Overview 

Transocean continued reshaping its offshore drilling fleet in 2018 by closing three significant transactions that 
transformed our fleet to be much younger and more technologically advanced, with a focus on ultra-deepwater 
and harsh environments, the two most promising sectors of the offshore drilling market. 

2018 was a transformative year at Transocean. We acquired Songa Offshore SE and Ocean Rig UDW Inc., 
and  invested  in  a  joint  venture  to  acquire,  complete  construction  of  and  operate  the  Transocean  Norge,  a 
technologically  advanced  harsh  environment  semisubmersible  drilling  rig.  These  strategic  acquisitions  and 
investments  during  the  downturn  for  offshore  drilling  position  Transocean  for  a  market  recovery  and 
demonstrate our commitment to remaining the industry’s leading offshore driller. 

During 2018, we strengthened our liquidity and financial position through solid operating results and 
executing  multiple  financing  transactions.  This  included  delivering  the  highest  Adjusted  Normalized 
EBITDA margin among offshore drillers and issuing approximately $3.0 billion of debt with maturities between 
2023 and 2025, while retiring $2.1 billion of debt with maturities primarily between 2018 and 2022. Additionally, 
we further bolstered our liquidity by successfully securing a new $1.0 billion, five-year undrawn revolving credit 
facility with an accordion feature offering an additional $500 million of capacity. 

Importantly,  we added  more  than  $2.0  billion  in  backlog  in  2018  –  the  most  since  2014.  This  amount 
equates to approximately 19 rig years of backlog. As of February 11, 2019, our contract backlog totaled U.S. 
$12.2  billion,  approximately  four  times  our  nearest  competitor.  Transocean  owns  or  has  partial  ownership 
interests in, and operates a fleet of 48 mobile offshore drilling units consisting of 31 ultra-deepwater floaters, 
13 harsh environment floaters, and four midwater floaters. Transocean is also constructing four ultra-deepwater 
drillships;  and  recently  accepted  delivery  of  the  newbuild,  Transocean  Norge, in  which  the Company  has  a 
33.0% interest. 

We delivered these strong results during a year when volatility continued in the offshore drilling sector. 
This was accomplished by maintaining our financial discipline and efficient operations with a constant focus on 
the safety of our workforce and the protection of the environments in which we operate. As a result of this we 
were able to generate revenue of approximately $3.0 billion and Adjusted Normalized EBITDA of approximately 
$1.0 billion and an Adjusted Normalized EBITDA margin of approximately 36%. Our fleet was also strengthened 
in 2018, as it has been in previous years during the downturn, by the retirement of eight older, less competitive 
rigs that were unlikely to be marketable going forward.     

The  business  highlights  below  demonstrate  our  Company’s  commitment  to  near-term  performance,  while 
preparing for a market recovery: 

● 

● 

● 

● 

In January, we acquired Songa Offshore SE, adding seven semisubmersibles to our fleet, including four 
high-specification, harsh environment CAT D rigs – the Transocean Equinox, Transocean Endurance, 
Transocean  Encourage  and  Transocean  Enabler  –  on  long-term  contracts  with  Equinor  ASA 
(“Equinor”). 
In February, the newbuild ultra-deepwater drillship Deepwater Poseidon commenced operations on its 
10-year contract with Shell in the U.S. Gulf of Mexico. The seventh generation dynamically positioned 
ultra-deepwater drillship can operate in water depths of 12,000 feet and can drill to depths of 40,000 
feet. 
In May, through a joint venture with funds managed and/or advised by Hayfin Capital Management LLP, 
we purchased a 33.0% interest in a newbuild harsh environment semisubmersible. The rig, named the 
Transocean Norge, is a Moss Maritime CS60 design vessel and is considered to be among the most 
capable newbuild semisubmersibles in the world. In the third quarter of 2018, the Transocean Norge 
received her maiden contract with Equinor in the Norwegian Continental Shelf. The contract is expected 
to commence in July 2019. 
In  December,  we  acquired  Ocean  Rig  UDW  Inc.,  adding  nine  high-specification  ultra-deepwater 
drillships,  two  harsh  environment  semisubmersibles  and  two  high-specification  ultra-deepwater

drillships  currently  under  construction  to  Transocean’s  existing  fleet.  This  acquisition  improves  our 
position to capitalize on an ultra-deepwater market recovery. 
Also, in December, we entered into an agreement with Chevron to enhance, complete, and operate one 
of our ultra-deepwater drillships that is currently under construction at the Jurong shipyard. The to-be-
named drillship will be the industry’s most capable, offering state-of-the-art technology, including dual 
20,000 psi blowout preventers, a first for an ultra-deepwater application; a derrick with gross hoisting 
capacity of 3.4 million pounds; and variable deckload capacity of 24,000 metric tons. The 5-year drilling 
contract for this rig added an estimated $830 million to our already industry-leading backlog. This was 
the largest contract we’ve executed since 2013. 

Throughout  2018,  Transocean  secured  additional  liquidity  to  withstand  the  downturn  while 
opportunistically  enhancing  its  fleet  in  anticipation  of  a  market  recovery.  Given  our  Company’s  long 
history as an industry-leading provider of offshore drilling services, we believe and continue to demonstrate that 
we  have  the  experience,  expertise  and  financial  discipline  necessary  to  effectively  manage  our  business 
throughout market cycles and deliver long-term value to our shareholders. With better visibility of improving 
market  fundamentals,  we  continue  to  take  actions  necessary  to  maintain  our  leadership  position  and 
strategically position Transocean for a market recovery.

Executive Compensation Philosophy, Strategy and Design 

The primary goal of our compensation program is to align pay with performance. We accomplish this goal by 
providing our executives with a competitive compensation package that rewards performance against specific, 
identified,  financial,  strategic  and  operational  goals  that  the  Compensation  Committee  of  the  Board  (the 
“Committee”)  believes  are  critical  to  the  Company’s  long-term  success  and  the  achievement  of  sustainable 
long-term shareholder returns. 

In administering our executive compensation program, we are guided by the following principal objectives: 

●  Aligning annual incentive compensation with financial and strategic objectives; and 

●  Rewarding absolute share price appreciation and relative performance in total shareholder return (“TSR”) 

through long-term equity incentive awards. 

P-58   Transocean 2019 Proxy Statement 

 
 
 
 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

We deliver the vast majority of executive pay as performance-based, “at-risk” incentive compensation, which is 
designed to balance short-term periodic results and long-term multi-year success of the Company and to build 
long-term shareholder value without excessive risk-taking. We believe the approach achieves our objective of 
aligning pay and performance.

Relationship Between Target and Realizable Pay   

The Summary Compensation Table reflects the grant-date fair value for share awards, as required. However, 
we believe that a better assessment of amounts earned through share awards can be made by considering our 
executives’ realizable pay, which was significantly lower than the grant-date fair value. While our performance-
based equity program resulted in payouts in only three of the last nine performance cycles, and the majority of 
outstanding stock options are currently underwater, the more recent, in-process long-term performance cycles, 
reflect our recent superior performance relative to our offshore drilling peers. 

The  graph  below  illustrates  the  effect  of  our  performance-based  compensation  programs  on  the  total 
compensation of our Chief Executive Officer and compares his targeted compensation to realizable pay as of

COMPENSATION DISCUSSION AND ANALYSIS 

2018 Compensation Program Overview   

In  2018,  the  Company  continued  to  reinforce  the  alignment  between  pay  and  performance  through  our 
executive compensation programs and compensation award levels.   

In  recognition  of  the  industry  downturn,  the  Committee  carefully  considered  appropriate  2018  target 
compensation  opportunities  for  our  Named  Executive  Officers.  In  close  consultation  with  their  independent 
compensation consultant, the Committee implemented the following executive compensation actions for our 
Named Executive Officers: 

●  Modifications to our peer groups, to improve alignment between the Company and the peers against 

whom the Committee’s compensation decisions are evaluated; 

●  Continuation of the freeze on base salaries for all Named Executive Officers who had no change in their 

role or position, marking the fourth consecutive year of the salary freeze; 

● 

● 

● 

Limitation  on  performance  share  awards  such  that  payouts  can  never  exceed  target  in  the  event 
absolute TSR performance is less than -15%; 

Expansion of the Company’s clawback policy to cover both forms of incentive compensation (cash and 
equity); 

Broadening of the Company’s definition of “cause” to allow for the cancellation of outstanding incentive 
compensation awards for actions that are inconsistent with our Code of Integrity; and 

●  Continuation  of  the  abolishment  of  all  executive  perquisites,  including  financial  planning,  annual 

physicals and club memberships, effective January 1, 2017. 

These  compensation  actions  reflect  our  focus  on  good  governance,  while  maintaining  prudently  designed, 
competitive compensation packages.   

Executive Compensation Setting 

We regularly review our executive compensation program to ensure that we provide the opportunity for each of 
our Named Executive Officers to receive competitive compensation without providing an incentive for excessive 
risk-taking. With support of its independent compensation consultant, the Committee annually reviews the total 
compensation  and  each  component  of  compensation  that  may  be  paid  or  awarded  to  each  of  our  Named 
Executive Officers and compares the total compensation and each component of compensation, as follows: 

●  Externally against the opportunities and amounts paid to executive officers holding comparable positions 
at  companies  with  which  we  compete  for  executive  talent,  positioning  elements  of  total  direct 
compensation at approximately the median; and 

● 

Internally  for  purposes  of  ensuring  internal  equity  and  taking  individual  performance,  skills,  and 
experience into account. 

We assess our compensation programs to ensure they are appropriately aligned with our industry sector and 
among companies in other industries of comparable size, international scope and organizational complexity. 
We also seek to provide a direct link between pay and the enhancement of shareholder value while achieving 
our vision and business strategy. 

The  Committee  employs  two  peer  groups  for  the  purpose  of  setting  executive  compensation.  The 
“Compensation  Peer  Group”  is  used  to  assess  the  competitiveness  of  the  compensation  of  our  Named 
Executive Officers, and the “Performance Peer Group” is used to evaluate the relative TSR performance of the 
Company. 

Transocean 2019 Proxy Statement  P-61

 
 
 
 
 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

Compensation Peer Group 

We  compete  for  executive  talent  across  many  different  sectors  around  the  world.  However,  our  primary 
competitive market generally includes other companies in the energy industry (oil and gas companies, offshore 
drilling companies and other energy services companies). In making compensation decisions for the Named 
Executive  Officers,  the  total  and  each  element  of  their  total  direct  compensation  are  compared  against 
published and publicly available compensation data. 

Considering  the  current  state  of  the  industry  and  in  consultation  with  the  Committee’s  independent 
compensation consultant, the 2018 Compensation Peer Group was modified. Our Compensation Peer Group 
review  considered  revenue  size  and  market  capitalization;  both  standard  industry  measures  in  developing 
compensation peer groups, to ensure continued alignment. The following four companies were removed from 
the 2018 compensation peer group due to concerns that they were too large, in terms of annual revenue and 
market  capitalization:  Baker  Hughes,  a  GE  company;  Canadian  Natural  Resources;  EOG  Resources  and 
Halliburton Company. They were replaced by the following three companies that are more comparable to the 
Company:  Hess  Corporation,  McDermott  International  and  Murphy  Oil  Corporation.  The  net  effect  of  these 
changes to the 2018 Compensation Peer Group composition reduced the average revenue size and market 
capitalization, thereby improving alignment with the Company’s current scope.     

As a result of these changes, the Compensation Peer Group for 2018 comprised the following companies: 

•  Anadarko Petroleum Corporation 
•  Apache Corporation 
•  Chesapeake Energy Corporation 
•  Devon Energy Corporation 
•  Diamond Offshore Drilling, Inc. 
•  Encana Corporation 
•  Ensco plc 

•  Hess Corporation 
•  Marathon Oil Corporation 
•  McDermott International 
•  Murphy Oil Corporation 
•  Nabors Industries Ltd.   
•  National Oilwell Varco, Inc.   
•  Noble Corporation plc 

•  Noble Energy, Inc.   
•  Petrofac Limited 
•  Seadrill Limited 
•  TechnipFMC plc 
•  Weatherford International plc 

In addition, we consider the compensation practices of general non-energy industry peers of comparable size 
and international scope in setting executive compensation levels and use general industry data as a secondary 
market reference to ensure that a comprehensive view of the market is considered. These non-energy general 
industry peers are expected to vary from year-to-year based on changes in the marketplace and the availability 
of  published  survey  data  for  companies  that  meet  the  defined  size,  international  scope  and  organizational 
structure criteria. 

Our target market position is determined based on the data believed to be most relevant for a given position. 
For  example,  the  Compensation  Peer  Group  data  are  weighted  more  heavily  for  most  positions,  whereas 
general  industry  data  are  also  considered  for  executives  overseeing  corporate  functions.  However,  in 
accordance  with  our  pay-for-performance  philosophy,  the  Compensation  Peer  Group  data  is  the  primary 
reference for assessing base salary, short-term incentive and long-term incentive compensation levels. 

Performance Peer Group   

The  Committee  establishes  a  Performance  Peer  Group  to  evaluate  the  Company’s  TSR  relative  to  that  of 
companies considered to be direct business competitors and competitors for investment capital. For 2016 and 
2017, the Committee approved a Performance Peer Group focused on offshore drillers to best align with our 
strategic business objectives. Beginning in 2018, the Committee expanded the Performance Peer Group by 
adding certain oilfield services companies to the existing offshore drillers, acknowledging consolidation within 

P-62   Transocean 2019 Proxy Statement 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

the offshore drilling sector and ensuring the Company’s performance peer group remained meaningfully large 
in order to effectively assess relative TSR.   

While the competition for executive talent spans a broader market as defined above in the Compensation Peer 
Group  section,  our  Performance  Peer  Group  is  specific  to  those  companies  with  expertise  in  technically 
demanding oilfield service operations. The Performance Peer Group for 2018 consisted of: 

•  Aker Solutions 
•  Diamond Offshore Drilling, Inc. 
•  Dril-Quip, Inc.   
•  Ensco plc 
•  Forum Energy Technologies, Inc.   
•  National Oilwell Varco, Inc. 
•  Noble Corporation plc 

•  Oceaneering International, Inc.   
•  Oil States International, Inc.   
•  Rowan Companies 
•  Saipem S.p.A. 
•  Subsea 7 S.A. 
•  TechnipFMC plc 

We will continue to assess the composition of the Performance Peer Group for 2019 and beyond, with a sharp 
focus on the impact of the current industry downturn and resulting consolidation.

and  business  strategy,  and  advancing  the  core  principles  of  our  compensation  philosophy  and  objectives 
without excessive risk. 

Base Salary 

Our Named Executive Officers receive base salaries constituting a basic level of compensation for services 
rendered during the year. The base salaries of our Named Executive Officers are determined by the Committee 
upon each officer’s initial hire and reviewed regularly, including in the context of promotions or other changes 
in job responsibilities. Each base salary is also reviewed by the Committee annually, both individually and, for 
internal pay equity purposes, relative to other Executive Officers. 

As part of its base salary review, the Committee considers input from our Chief Executive Officer (except with 
respect to his own compensation), competitive compensation data from our Compensation Peer Group and 
other survey data, job responsibilities, individual skills, experience and expected future contributions of each 
Named Executive Officer. The Committee also considers input from its independent compensation consultant 
within the framework of the Company’s compensation philosophy and objectives. 

In  February  2018,  the  Committee,  in  consideration  of  the  industry  downturn,  and  with  consultation  from  its 
independent compensation consultant, elected to freeze base salaries for our Named Executive Officers, with 
the exception of Mr. Long, who was promoted to Executive Vice President and General Counsel. Mr. Long is 
the only individual who, while an Executive Officer, has received a base salary increase since 2015.   

The following base salaries in U.S. dollars were approved by the Committee for the individuals listed below.

Annual Performance Bonus 

Our Performance Award and Cash Bonus Plan (the “Bonus Plan”) is a formulaic, goal-driven plan that provides 
participants, including the Named Executive Officers, with the opportunity to earn annual cash bonuses based 
on performance as measured against predetermined performance objectives. Individual target award levels, 
expressed as percentages of the participants’ base salaries, are established by the Committee at the beginning 
of  the year.  The  target  award  opportunities  under  the  Bonus  Plan,  when  combined  with  base  salaries,  are 
intended to position the participants to earn total cash compensation approximating competitive market median 
levels. Individual awards correlate to Company performance, so the executives achieve above-target awards 
only when the Company achieves above-target performance. Further, the bonus opportunity is capped at a 
maximum payout level as noted below. 

Under the Bonus Plan for 2018, the Named Executive Officers had a potential payout range of 0% to 200% of 
their individual target award opportunity. The 2018 target bonus opportunity for each Named Executive Officer, 
expressed as a percentage of base salary, was as follows:

COMPENSATION DISCUSSION AND ANALYSIS 

2018 Bonus Structure and Achievement 

The annual cash bonus structure was designed to recognize and incent strong financial, operational and safety 
performance. These three focus areas have a direct line of sight to annual company operational and financial 
results while maintaining a strong focus on personnel,  industrial and environmental safety. This structure is 
designed to focus on those areas where we can differentiate ourselves from our competitors during the industry 
downturn and be well-positioned to outperform the competition in the market recovery. 

Each  measure,  relative  weighting,  and  the  threshold-target  maximum  payout  range  was  designed  with 
reference to our 2018 business plan, as presented to the Committee in early February 2018, and our 2017 
performance results. 

The  following  chart  outlines  the  2018  bonus  performance  measures  and  relative  weightings.  Each  of  the 
measures is defined and discussed in more detail below.

Safety Performance 

Our business involves numerous operating hazards, and we are strongly committed to protecting our personnel, 
our property and our environment. Our goal is expressed in our safety vision of “an incident-free workplace all 
the time, everywhere.” Beginning in 2017, the safety component of the bonus structure has focused on Total 
Recordable Incident Rate (“TRIR”). We establish threshold, target, and maximum levels of TRIR performance 
for the purposes of assessing any incentive payout from this metric. In addition, the bonus structure provides 
for a 25% reduction to the TRIR calculated payout for any Tier 1 Operational Integrity event (see definition 
below). The Committee elected to carry forward this methodology and weighting for 2018.   

Developing Our Total Recordable Incident Rate (TRIR) Target   

TRIR is a safety performance metric recognized by the U.S. Occupational Safety & Health Administration and 
is used by companies across an array of industries. We calculate TRIR based upon the guidelines set forth by 
the industry’s International Association of Drilling Contractors (the “IADC”). The IADC methodology calculates 
TRIR by taking the aggregate number of occurrences of work-related injuries or illnesses that result in any of 
the following: death; a physician or licensed health care professional recommending days away from work due 
to an injury or illness; an employee not being able to perform all routine job functions (but not resulting in days 
away from work); or any other medical care or treatment beyond minor first aid. The TRIR is the number of 
such occurrences for every 200,000 employee hours worked.

COMPENSATION DISCUSSION AND ANALYSIS 

The Committee approved a TRIR target for 2018 of 0.25. In setting this target, the Committee received input 
from  the  Board’s  Health,  Safety  and  Environment  (HSE)  Committee,  comprised  of  independent  directors. 
Values above and below this target were calculated in accordance with the chart below, with outcomes falling 
between the two boundaries interpolated on a straight-line basis: 

TRIR Target and Performance Range 
Maximum = 0.21 
Target = 0.25 
Minimum = 0.29 

Bonus Payout 
200%
100%
0%

As noted above, the year-end TRIR payout is reduced by 25% for any Tier 1 Operational Integrity event during 
the year, regardless of formulaic performance achievement. Furthermore, the Committee evaluates whether to 
apply discretion in response to unforeseen, extraordinary circumstances in considering overall bonus results.   

In setting the 2018 TRIR threshold-target-maximum values, the Committee considered the following: 

● 

● 

● 

Integration of the Songa Offshore SE fleet following the January 2018 acquisition; 

Planned and anticipated increases in rig startups and reactivations; and 

An  increase  in  rig  crew  hiring  and  the  need  to  train  these  new  employees  in  the  Company’s  safety 
programs and processes. 

With consideration given to these factors and the recognition that this increased activity would challenge the 
Company’s ability to improve upon what was the lowest annual TRIR in the Company’s history, the Committee 
approved  the  2018  TRIR  target  at  0.25,  which  approximated  the  blending  of  the  2017  actual  results  for 
Transocean and Songa Offshore SE. The target represented a challenging yet realistic goal as we integrated 
the operations and practices of Songa Offshore within the safety management system of Transocean. 

In setting the threshold and maximum values, the Committee applied a 15% range above and below the 0.25 
target. This range created a minimum, or entry point, of 0.29 and a maximum of 0.21.     

Further,  the  Committee  recognized  the  impact  of  Operational  Integrity  on  process  safety  performance. 
Operational Integrity is an internally developed safety measure designed to prevent, or mitigate the impact of, 
a significant event. We use industry standard definitions of significant events, which include: 

●  Fire, explosion, release of a hazardous substance with serious injury or fatality; 

●  Other circumstances resulting in serious injuries/fatalities; 

●  Major structural damage to Company property; and 

●  Uncontrolled release of hazardous fluids. 

Consistent with our 2017 Bonus Plan design, a Tier 1 event, as defined in the Company’s Health and Safety 
Policies and Requirements, is the most serious Operational Integrity event, requiring immediate and potentially 
significant Company time and resources to rectify. 

Measuring Total Recordable Incident Rate (TRIR) Results   

The  2018  formulaic  result  for  TRIR  was  0.37,  which  fell  below  threshold  performance  and  resulted  in  zero 
payout for the safety component of the 2018 Bonus Plan. While we were disappointed that the Company did 
not continue its track record of continuous improvement in TRIR, compared to prior years, we were encouraged 
by the overall 2018 safety performance for the following reasons:

COMPENSATION DISCUSSION AND ANALYSIS 

●  The Company experienced no Lost Time Incidents in 2018, a standard never previously achieved by the 

Company for a full calendar year; 

●  The  majority  of  incidents  counted  in  TRIR  did  not  present  the  potential  of  escalating  to  a  Lost  Time 

Incident; 

●  Half our operating rigs did not experience any incidents counted in TRIR; and 

●  The Company experienced no Tier 1 events. 

Despite  these  encouraging  circumstances,  the  formulaic  performance  of  TRIR,  resulted  in  zero  percent  for 
2018, as illustrated.

Financial Performance 

Developing Our EBITDA Target   

For  the  2018  Bonus  Plan,  the  Committee  evaluated  financial  measures  that  would  most  closely  align 
management with the Company’s financial objectives. The Committee concluded that Earnings Before Interest, 
Taxes,  Depreciation  and  Amortization  (“EBITDA”)  would  be  the  most  appropriate  measure,  consistent  with 
2017, based on the following reasons: 

● 

It is commonly used by our shareholders to evaluate financial performance, in light of current market 
conditions; 

● 

It is commonly used by our peers to evaluate their own financial performance; and 

●  While  it  is  a  non-GAAP  financial  measure,  it  is  objective  and  reconcilable  to  the  GAAP  measures 

reported in our financial statements. 

The Committee weighted EBITDA at 60% of the total 2018 Bonus Plan opportunity.   

In establishing the EBITDA target and range, the Committee considered the Company’s 2018 financial plan, as 
presented by management in early February 2018. Threshold and maximum performance outcomes were then 
set based on the potential for decreases or increases to financial outcomes tied to dynamic market conditions. 
While the 2018 EBITDA target was set below the 2017 actual financial result, the target objectively reflected 
the continuing industry downturn and related financial challenges, including uncertainties with respect to the 
recontracting of rigs whose contracts were set to expire in 2018.

The Company delivered strong EBITDA results for 2018, despite limited demand for rigs and declining or flat 
contract dayrates. Outstanding operating performance and revenue efficiency for deployed rigs, combined with 
a strong focus on cost management, resulted in strong EBITDA results, relative to target performance and to 
peers.   

Included in this proxy statement, attached as Appendix A, is a reconciliation of EBITDA to net income, the most 
directly  comparable  GAAP  financial  measure.  The  differential  between  actual  EBITDA  and  EBITDA 
performance achievement for the 2018 Bonus Plan is the result of a Committee-approved calculation of EBITDA 
to reflect the following discrete items: 

● 

Purchase Price Accounting Adjustment. The transaction to acquire Songa Offshore closed on January 
30,  2018.  Consistent  with  US  GAAP,  management  calculated  the  Purchase  Price  Adjustment 
associated with this transaction as part of the next Form 10-Q filing in May 2018, and management 
determined that the Company was required to make a purchase price adjustment in connection with 
this  acquisition.  The  entry  could  not  have  been  included  in  the  2018  financial  plan  presented  to  the 
Committee  in  February  2018,  as  it  had  not  yet  been  calculated.  If  the  acquisition  had closed  in  late 
2017, the adjustment would have been included in the 2018 financial plan, and the EBITDA target would 
have been accordingly adjusted downward. 

●  Rig Reactivation. After management presented the 2018 financial plan to the Committee, an unexpected 
contracting opportunity arose for the Development Driller III – a rig that had been idle. The opportunity 
was for a strategic customer in West Africa, a critical market for ultra-deepwater rigs, and reactivating 
idle rigs for promising commercial opportunities is a critical component to the Company’s plan for long-
term EBITDA growth. While the contract was scheduled to commence in 2019, the reactivation costs to 
prepare  the  rig  for  the  contract  would  be  incurred  in  2018.  Management,  in  consultation  with  the 
Committee, pursued and ultimately won the contract, despite the adverse impact on 2018 EBITDA. The 
Committee believes that one of its duties is to make sure that the executive compensation program 
does not lead to unintended adverse outcomes – i.e., results that are against the shareholders’ best 
interests.  Accordingly,  the  Committee  evaluated  the  circumstances  surrounding  the  contract  and 
determined  that,  were  the  reactivation  costs  included  in  the  2018  EBITDA  performance  calculation, 
management would be improperly penalized for acting in the shareholders’ best interest. As a result, 
the  Committee  concluded  that  the  costs  should  be  excluded  from  the  calculation  of  2018  EBITDA 
performance. The Committee further determined that the revenue from the contract would be included 
in the 2019 EBITDA target, so that the Executive Officers do not improperly benefit from this decision 
in 2019. 

●  Contract Blend and Extend. In mid-2018, management was approached by a customer requesting a 
“blend and extend” of its current contract. As background, a “blend and extend” is an exchange between 
the customer and the Company: the customer reduces the dayrate in the short-term, but extends the 
contract beyond its current term, adding critical backlog and financial security to the Company’s contract 
portfolio. Not every “blend and extend” is in the Company’s best interest; the circumstances that dictate 
whether such an arrangement is commercially viable vary (e.g., amount of the reduction in dayrate, 
length  of  extended  term,  competing  prospects  for  the  rig).  In  consultation  with  the  Committee, 
management elected to enter into the arrangement, as doing so extended the term of the contract by 
two years at a favorable dayrate. The Committee believes that had the reduction in the 2018 dayrate 
not been addressed in the EBITDA performance calculation, management would have been improperly 
penalized  for  making  a  commercial  decision  that  was  clearly  in  the  shareholders’  best  interests.  As 
noted  above,  the  Committee  works  closely  with  management,  in  consultation  with  the  Committee’s 
independent compensation consultant, to make sure that the executive compensation program does 
not lead to unintended adverse consequences. Calculating EBITDA to set aside the marginal impact of 
the reduced dayrate in connection with this outstanding commercial opportunity is consistent with that

COMPENSATION DISCUSSION AND ANALYSIS 

priority. As with the rig reactivation noted above, the Committee further determined that the revenue 
from the contract would be included in the EBITDA target for future periods so that the Executive Officers 
do not improperly benefit from this decision in subsequent years. 

As illustrated, even after adjustments, the EBITDA result fell short of our goal, performing at 90% to target, with 
an associated weighted payout of 54% of the total target bonus opportunity for each of the Named Executive 
Officers.

Operational Performance 

Developing Our Uptime Target 

In 2017, Uptime was identified as the operational performance measure that would best align with the interests 
of our customers and, ultimately, our shareholders; therefore, we elected to maintain this measure for 2018. 
This measure represented 20% of the 2018 total target annual bonus opportunity, reinforcing the importance 
of  maintaining  excellence  in  our  rig  operations.  We  believe  that  Uptime  is  the  best  measure  of  operational 
efficiency, which is imperative to our customers. 

While Uptime is a common operational metric in our industry, it has no standard industry definition or reporting 
structure. As a result, the Company has developed its own definition, in consultation with the Committee, and 
that definition recognizes the key impediments to Uptime: equipment failures and human performance errors. 

Uptime  is  measured  as  total  operating  hours,  minus  downtime  hours,  expressed  as  a  percentage  of  the 
maximum total operating hours. Operating hours are defined as the number of hours a rig is operating under a 
contract. Downtime is defined as the number of hours the rig is not engaged in drilling activities, resulting from 
mechanical  failure  or  human  performance  error.  Using  this  formula,  zero  mechanical  failures  and  human 
performance  errors  would  result  in  a  rig  operating  at  100%  Uptime.  Downtime  events  detract  from  optimal 
performance and have a direct negative impact on the customer’s operational plan. 

In  setting  the  threshold-target-maximum  range  for  this  measure,  the  mathematical  differential  of  3%  from 
threshold to maximum is significant considering the  total number of operating hours during a calendar year 
(e.g., approximately 250,000 hours of operation in 2018). 

The Committee approved the following Uptime target for 2018:

COMPENSATION DISCUSSION AND ANALYSIS 

In setting the 2018 Uptime target, the Committee considered the Company’s outlook for 2018, which featured:   

●  The reactivation of three rigs and the start-up of one rig in the U.S. Gulf of Mexico; 

●  The mobilization of five rigs to new countries, with new customers; and 

●  The hiring of approximately 2,500 new employees, including approximately 900 employees joining the 

Company through the acquisition of Songa Offshore SE.   

These factors led the Committee to conclude that the risk of equipment failure and human performance errors 
was  elevated  for  2018,  compared  to  2017.  Despite  this  incremental  risk,  in  support  of  its  desire  to  drive 
continuous improvement, the Committee decided to maintain the challenging target from 2017, and approved 
the 2018 Uptime target at 96.0%. 

Measuring Uptime Results   

Based on this high level of operational efficiency, the Company achieved 96.2% Uptime performance in 2018. 
This increase over target performance equates to approximately 500 hours, or 21 days, of additional operational 
productivity across the fleet, resulting in greater customer satisfaction and higher earnings. 

As illustrated, the formulaic performance of Uptime achieved 115% performance to target and an associated 
weighted payout of 23% of the total target bonus opportunity for each of the Named Executive Officers.

Long-Term Incentives 

The  Committee  establishes  competitive  long-term  incentive  (“LTI”)  opportunities  for  our  Named  Executive 
Officers that motivate them to increase total shareholder return, drive long-term sustainable value and align the 
interests of participants with those of shareholders. LTI opportunities vary in the actual value delivered, based 
on the Company’s actual total shareholder return.   

Transocean 2019 Proxy Statement  P-71

 
 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

To provide an appropriate balance of incentives tied to performance, three types of long-term equity instruments 
were  used  in  2018:  Performance  Units  (“PSUs”),  Restricted  Share  Units  (“RSUs”)  and  Non-Qualified  Stock 
Options (“NQSOs”). The weighting of each instrument in our LTI program was as follows: 

Long-Term Incentive Pay Mix

RSUs
25%

NQSOs
25%

PSUs
50%

This LTI mix is designed to ensure that a minimum of 50% of total LTI is conveyed through PSUs. RSUs are 
included in the incentive mix to reinforce a direct relationship to the shareholder experience and to promote 
ownership of Company equity. Stock Options only deliver value to the executive when the Company’s share 
price  appreciates  following  the  grant  date.  All  three  equity  instruments  are  also  designed  to  be  retentive  in 
nature through multi-year performance and vesting periods. 

The following LTI award values were delivered to our Named Executive Officers in 2018.

1,800,590 
2,439,821 

Performance Units (PSU) 

The target value of the 2018 PSU grants to each of the Named Executive Officers was approximately 50% of 
each officer’s total 2018 LTI award target value. 

Each PSU represents one share and is earned based on performance over a three-year cycle from January 1, 
2018 through December 31, 2020. Performance is determined by comparing the Company’s TSR performance 
relative to the Company’s Performance Peer Group over the three-year performance cycle. 

In further recognition of the importance of shareholder alignment, the Committee capped the earning of PSUs 
at  target  if  the  Company’s  absolute  TSR  during  the  performance  period  is  less  than  negative  15%.  The 
Committee  set  the  cap  at  this  level  to  ensure  that  management  does  not  benefit  disproportionately  from 
shareholder returns that are more than marginally negative. 

P-72   Transocean 2019 Proxy Statement 

 
 
 
     
 
 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

Actual  results  at  the  completion  of  the  three-year  performance  cycle  will  be  determined  by  the  following   
ranking of TSR performance: 

Company Ranking

100%

25th Percentile

Upon completion of the 2018 - 2020 PSU performance cycle, the Committee will determine final payout levels, 
if any, and PSUs will be distributed to the Named Executive Officers, along with a cash payment equal to any 
dividends or equivalents for earned shares that may have accrued during the performance cycle.   

Restricted Share Units (RSU) 

The target value of the 2018 RSU grants to each of the Named Executive Officers was approximately 25% of 
each officer’s total 2018 LTI award target value. 

Time-vested RSUs were granted to all Named Executive Officers as part of the 2018 annual long-term incentive 
grants. Each RSU represents one share and vests over a three-year schedule (ratably one-third each year), 
contingent upon continued service. 

Non-Qualified Stock Options (NQSO) 

The target value of the 2018 NQSO grants to each of the Named Executive Officers was approximately 25% of 
each officer’s total 2018 LTI award target value. 

Time-vested NQSOs were granted to each Named Executive Officers as part of the 2018 LTI grants. Each 
NQSO represents the option to purchase one share and vests over a three-year schedule (ratably one-third 
each year), contingent upon continued service. 

Realized Long-Term Incentive Compensation for 2018 

In  2019,  the  Committee  evaluated  the  Company’s  performance  for  the  three-year  performance  period  from 
January 1, 2016 through December 31, 2018, and determined the performance to be 133% of target based on 
the  Company’s  TSR  relative  to  the  Performance  Peer  Group.  However,  in  recognition  of  the  importance  of 
shareholder  alignment,  the  Committee  capped  the  earning  of  PSUs  at  target  as  a  result  of  the  Company’s 
absolute  TSR  being  less  than  negative  15%  during  the  performance  period.  Thus,  the  actual  payout  was 
reduced to 100%, or target.   

Employment Agreements with Named Executive Officers 

Employment  agreements  with  our  Executive  Management  Team  comply  with  the  Minder  Ordinance,  which 
prohibits the payment of severance benefits to members of the Executive Management Team. Other than the 
individual compensation terms applicable for each executive, the same basic form of employment agreement 
was used for Named Executive Officers with agreements. 

Transocean 2019 Proxy Statement  P-73

 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

Expatriate Benefits 

For employees who accept an international assignment, we have provided certain expatriate benefits, including 
housing, car, cost of living allowances and educational expenses for dependent children. These benefits are 
designed to help defray the significant expense associated with expatriation. Beginning in 2014, we eliminated 
the tax protection and tax equalization aspects of these benefits for our Named Executive Officers.   

In 2018, Mr. Adamson was the only Named Executive Officer eligible for expatriate benefits, the value of which 
is included in the Summary Compensation Table under “All Other Compensation” and described in the notes 
to that table. Effective December 31, 2018, Mr. Adamson ceased to be eligible for any expatriate benefits and, 
as  a  result,  effective  January  1,  2019, the  Company  has  no Named  Executive  Officers  receiving  expatriate 
benefits.   

Indirect Compensation 

In addition to base salary, annual and long-term incentive compensation, we offer limited indirect compensatory 
arrangements  to  our  executives.  These  indirect  elements  of  executive  compensation  are  not  performance-
based and are offered as part of the overall compensation package to ensure that the package is competitive 
with  other  companies  with  which  we  compete  for  talent.  Below  is  a  summary  of  the  indirect  elements  of 
compensation for our Named Executive Officers. 

Health, Welfare and Retirement 

Our Named Executive Officers are eligible for Company-wide benefits on substantially the same basis as other 
full-time  employees,  including  savings,  frozen  pension,  medical  and  life  insurance  benefits.  Our  Named 
Executive Officers also receive a supplemental life insurance benefit equal to four times base salary capped at 
a  maximum  of  U.S.  $1  million.  In  addition,  we  make  a  supplemental  non-qualified  defined  contribution 
restoration plan available to employees (including the Named Executive Officers) to compensate for benefits 
that otherwise would be unavailable due to U.S. Internal Revenue Service limits on qualified retirement plans. 

Perquisites 

The  Committee  elected  to  eliminate  all  executive  perquisites  for  our  Named  Executive  Officers,  effective 
January 1, 2017. As a result, none received perquisites in 2018. 

Post-Employment Compensation 

We believe that the competitive marketplace for executive talent and our desire to retain our Executive Officers 
require  us,  subject  to  compliance  with  applicable  law,  to  provide  our  Executive  Officers  with  a  severance 
package. Each of our Executive Officers who are not members of our Executive Management Team is eligible 
to receive severance benefits in the event we choose to terminate the Executive Officer at our convenience. 
Subject to Committee approval, the benefits provided in the event of an involuntary termination under the terms 
of our Executive Severance Benefit Policy include a cash severance benefit limited to 52 weeks of base salary; 
a  pro  rata  share  of  the  termination year’s  award  under  the  Bonus  Plan  for  such  executive;  treatment  of 
outstanding long-term incentive awards as provided for in the terms and conditions of each award (as more 
fully described under “Executive Compensation—Potential Payments Upon Termination or Change of Control”); 
and outplacement services not to exceed 5% of the base salary of the executive. 

We also believe that the interests of our shareholders are served by including a double-trigger change-of-control 
provision in the Bonus Plan and the Long-Term Incentive Plan for Named Executive Officers who would be 
integral to the success of, and are most likely to be impacted by, a change of control. By requiring two triggering 
events to occur, we believe that those Executive Officers who remain with us through a change of control will 
be  appropriately  focused  on  the  success  of  the  combined  enterprise  while  those  who  depart  because  of  a 
change of control will be appropriately compensated. The types of payments that will be made to our executives, 
along with estimated values as of December 31, 2018, are described under “Executive Compensation-Potential 
Payments Upon Termination or Change of Control.” 

P-74   Transocean 2019 Proxy Statement 

 
 
COMPENSATION DISCUSSION AND ANALYSIS 

The  Committee  periodically  reviews  severance  packages  offered  to  the  Executive  Officers  to  ensure  the 
benefits are aligned with prevailing market practices. For a Named Executive Officer to receive the benefits 
described above, the Named Executive Officer must first sign a release of all claims against the Company and 
enter  into  a  non-competition  and  confidentiality  agreement  covering  our  trade  secrets  and  proprietary 
information. 

The  Minder  Ordinance  prohibits  certain  types  of  compensation  payments  to  members  of  the  Executive 
Management  Team,  including  severance  payments  in  any  form.  Therefore,  members  of  the  Executive 
Management Team are not eligible to participate in the Executive Severance Benefit Policy.   

In  June  2018,  Mr.  Stobart  announced  his  retirement  from  the  position  of  Executive  Vice  President,  Chief 
Operating Officer and Chief Performance Officer and, in accordance with the terms of Mr. Stobart’s employment 
agreement, has continued to receive his base salary plus an amount equal to the pro-rata portion of his target 
bonus during the applicable 12-month notice period.   

Executive Compensation Governance, Policy and Practice 

The Committee is responsible for the executive compensation program design and decision-making process. 
The Committee solicits input from independent members of the Board of Directors, the Chief Executive Officer, 
other members of management, and the independent compensation consultant to assist with its responsibilities. 
The following summarizes the roles of each of the key participants in the executive compensation decision-
making process. 

Transocean 2019 Proxy Statement  P-75

 
 
COMPENSATION DISCUSSION AND ANALYSIS 

Compensation Committee 

The Committee is composed solely of members of the Board of Directors who (i) are not employees of the 
Company, (ii) meet the independence requirements of the NYSE, and (iii) meet the qualifications of outside 
directors  under  Section  162(m)  of  the  U.S.  Internal  Revenue  Code.  The  Committee  is  responsible  for 
overseeing  our  executive  compensation  and  long-term  incentive  programs.  Specifically,  the  Committee  is 
responsible for: 

●  Reviewing and approving the target and actual compensation paid and the benefit levels received by 

our Executive Officers; 

● 

● 

● 

● 

● 

Annually recommending focus areas for our Chief Executive Officer for approval by the members of our 
Board of Directors who meet the independence and experience requirements set forth in the Committee 
charter; 

Annually evaluating all aspects of our Chief Executive Officer’s performance in light of these focus areas 
(with the participation of all non-executive members of the Board of Directors,) and setting our Chief 
Executive  Officer’s  compensation  based  on  this  evaluation  and  after  reviewing  data  concerning 
compensation practices in the competitive market; 

Establishing and approving our executive compensation plans and arrangements to provide benefits to 
our Executive Officers in accordance with the goals and objectives of the Company, as established by 
the Board of Directors; 

Administering the Company’s LTI plans, including determining plan eligibility and approving individual 
awards for all plan participants; 

Administering  the  Company’s  Performance  Award  and  Cash  Bonus  Plan  and  approving  individual 
awards for all Executive Officers; 

●  Considering  and  approving  executive  employment  and,  to  the  extent  permissible  under  Swiss  law, 
severance agreements or other contractual agreements that may be entered into with our Executive 
Officers (that shall not include “single-trigger” change-in-control agreements); 

●  Reviewing and discussing this Compensation Discussion and Analysis, the Company’s Swiss statutory 
compensation  report  and  maximum  aggregate  compensation  limits  for  the  Board  of  Directors  and 
members of the Executive Management Team with our management and, based upon such review and 
discussion, recommending to the Board of Directors that the Compensation Discussion and Analysis 
be included in the proxy statement for our Annual General Meeting or our annual report, as applicable; 
and 

● 

Assessing the risks associated with the Company’s compensation arrangements. 

During 2018, the Compensation Committee consisted of three directors: Tan Ek Kia (Chairman), Frederico F. 
Curado, and Vincent J. Intrieri. 

Independent Compensation Consultant 

To assist in discharging its responsibilities, the Committee engaged an independent executive compensation 
consulting firm, Pay Governance LLC, which advised the Committee on executive compensation matters for 
2018. 

In order not to impair the independence of the Committee’s compensation consultant or create the appearance 
of such an impairment, the Committee adopted a policy that any compensation consultant to the Committee 
may not provide other services to the Company in excess of U.S. $100,000. Neither Pay Governance nor any 
of its affiliates provided the Company with any other services in 2018. In May 2018, the Committee assessed 
whether the work of Pay Governance for the Committee during 2018 raised any conflict of interest by conducting 
a  review  of  several  independence  factors,  which  included  the  factors  set  forth  under  Rule  10C-1  of  the 

P-76   Transocean 2019 Proxy Statement 

 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

Exchange  Act.  The  Committee  concluded  that  no  conflict  of  interest  was  raised  that  would  prevent  Pay 
Governance from independently advising the Committee. 

In advising the Committee, the compensation consultant reports to and acts at the direction of the Committee. 
The Committee directs the compensation consultant in the performance of its duties under its engagement to 
provide certain guidance on an ongoing basis, including: 

● 

● 

Expertise on compensation strategy and program design; 

Information relating to the selection of the Company’s peer groups; 

●  Relevant market data and alternatives to consider when making compensation decisions; 

● 

● 

● 

Assistance in establishing and updating annual and long-term incentive guidelines; 

Periodic reviews of the total executive compensation program; and 

Support  and  advice  as  the  Committee  conducts  its  analysis  of  and  makes  its  decisions  regarding 
executive compensation. 

The Committee does not necessarily adopt all recommendations given by the compensation consultant but 
uses  the  consultant’s  work  as  a  reference  in  exercising  its  own  judgment  with  respect  to  its  own  executive 
compensation actions and decisions. 

The  compensation  consultant  participates  in  every  meeting  of  the  Committee  and  meets  privately  with  the 
Committee at the Committee’s request. Our management provides information to the consultant but does not 
direct or oversee its activities with respect to our executive compensation program. 

Other Advisors 

From time-to-time, management engages other advisors to assist in providing advice to the Committee. Such 
advisors have included, among others, an outside law firm to provide advice regarding various legal issues, 
financial analysts to examine relevant performance metrics and an outside actuarial firm to evaluate benefit 
programs. The Committee evaluates these advisors for independence, when retained. No advisors other than 
Pay Governance were hired in 2018. 

Management 

Our Chief Executive Officer annually reviews the competitive pay position and the performance of each member 
of senior management other than himself. Our Chief Executive Officer’s conclusions and recommendations, 
including base salary adjustments and award amounts for the current year and target annual award amounts 
for the next year under our Bonus Plan (other than for himself,) are presented to the Committee. The Committee 
makes all compensation decisions and approves all share-based awards for the Named Executive Officers and 
other Executive Officers. The Committee may exercise its discretion in modifying any compensation element 
to any Executive Officer, including reducing or increasing the payment amount for one or more components of 
such awards. 

Officers and other employees in our Human Resources Department assist our Chief Executive Officer with his 
recommendations and develop and present other recommendations regarding compensation to the Committee 
as  needed.  Our  officers  and  other  employees  participate  in  Committee  discussions  in  an  informational  and 
advisory capacity and have no authority in the Committee’s decision-making process. 

Share Ownership Guidelines for Executives 

We believe it is important for our Named Executive Officers to build and maintain an appropriate equity stake 
in the Company. The Company’s share ownership guidelines for Named Executive Officers are intended to 
further  align  executives’  interests  with  the  interests  of  our  shareholders.  Under  these  guidelines,  Named 

Transocean 2019 Proxy Statement  P-77

 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

Executive Officers must retain 50% of any shares that vest (net of tax shares) until the ownership guidelines 
are met. Each of our Named Executive Officers must own an amount of shares equivalent to the following: 

CEO 

6x Base Pay

Executive  Vice  President 

3x Base Pay

Senior  Vice  President

2x Base Pay

Vice  President

1x Base Pay

Compliance with this policy is reviewed by the Committee, and executives must certify their compliance on an 
annual basis. The Committee may exercise its discretion in response to any non-compliance of this policy. The 
Committee has determined that all executives meet or exceed their minimum ownership requirements. 

Executive Compensation Recoupment/Clawback Policy 

Under the Incentive Compensation Recoupment Policy, the Company is authorized to recover or adjust both 
cash and equity incentive compensation to the extent the Committee determines that payments or awards have 
exceeded the amount that would otherwise have been received, due to a restatement of financial results or if 
the  Committee  determines  that  an  executive  has  engaged  in,  or  has  knowledge  of,  and  fails  to  prevent  or 
disclose, fraud or intentional misconduct pertaining to any financial reporting requirement. 

No Hedging or Pledging of Company Shares 

We have a policy that prohibits any employee, officer or director of the Company from engaging in short-term 
or speculative transactions in the Company’s securities. It, therefore, is the Company’s policy that employees, 
officers and directors and their family members or wholly-owned businesses not engage in any of the following 
transactions:   

●  Short sales; 

●  Publicly Traded Options; 

●  Hedging Transactions; and 

●  Margin Accounts and Pledging. 

Our Executive Officers and directors must certify compliance with the hedging and pledging provisions of our 
Insider Trading Policy on an annual basis, and all have done so. 

Use of Tally Sheets 

The  Committee  reviews  compensation  tally  sheets,  prepared  by  management,  that  present  comprehensive 
data on the total compensation and benefits package for each of our Named Executive Officers. Tally sheets 
include  all  current  compensation  obligations,  as  well  as  additional  analyses  with  respect  to  payments  at 
hypothetical terminations to consider the Company’s obligations under such circumstances. The Committee 
does  not  use  the  tally  sheets  to  determine  the  various  elements  of  compensation  or  the  actual  amounts  of 
compensation to be approved but, rather, to evaluate the Company’s obligations under the various programs.     

Tax Impact on Compensation 

Prior to 2018, Section 162(m) of the Internal Revenue Code (“Section 162(m)”) limited the annual tax deduction 
to $1,000,000 for compensation paid by a publicly held company to its Chief Executive Officer and each of its 
three other most highly compensated Named Executive Officers other than the Chief Financial Officer, unless 
the compensation was designed to meet certain performance-based requirements. Under the Tax Cuts and 
Jobs Act of 2017 (the “2017 Tax Act”), effective for our taxable year beginning January 1, 2018, the exception 
under Section 162(m) for performance-based compensation is no longer available, subject to transition relief 

P-78   Transocean 2019 Proxy Statement 

 
 
 
 
 
 
COMPENSATION DISCUSSION AND ANALYSIS 

for certain grandfathered arrangements in effect as of November 2, 2017. In addition, the “covered employees” 
subject to Section 162(m) limitations will be expanded to include our Chief Financial Officer, and once one of 
our Named Executive Officers is considered a covered employee for 2017 or later, the Named Executive Officer 
will remain a covered employee so long as he or she receives compensation from the Company. To the extent 
practicable, we intend to preserve future deductions related to existing compensation arrangements that are 
eligible for transition relief under the 2017 Tax Act, but we reserve the right to use our judgment to authorize 
compensation payments that are not deductible under Section 162(m) when we believe that such payments 
are  appropriate  and  in  the  best  interest  of  shareholders,  after  taking  into  consideration  changing  business 
conditions or the executive’s individual performance and/or changes in specific job duties and responsibilities.

Transocean Savings Restoration Plan 

The  Company  maintains  the  Transocean  Savings  Restoration  Plan,  a  nonqualified,  unfunded,  defined 
contribution  plan  for  key  management  employees  who  earn  compensation  in  excess  of  certain  limits  in  the 
Internal Revenue Code. All Named Executive Officers participate in this plan. Effective January 1, 2017, all 
participants  in  this  plan  are  fully  vested.  The  plan  provides  that  eligible  participants  receive  an  annual 
contribution equal to 10% (or such other percentage as determined by the administrative committee) of the 
compensation  earned  in  a  particular  calendar  year  that  is  in  excess  of  the  Internal  Revenue  Code  limits.

EXECUTIVE COMPENSATION 

Compensation considered under this plan includes basic salary and annual performance bonus. A participant 
must be employed on the last day of the calendar year in order to receive a contribution for a particular year. 
Benefits are payable upon a participant’s termination of employment, or six months after termination in the case 
of certain officers.   

Transocean U.S. Retirement Plan 

The Transocean U.S. Retirement Plan is a tax-qualified pension plan. Benefit accruals under this plan were 
frozen effective as of December 31, 2014. Messrs. Adamson and Stobart are the only Named Executive Officers 
who participate in this plan. 

The purpose of the plan is to provide post-retirement income benefits to employees in recognition of their long-
term  service  to  the  Company.  Benefits  available  to  executives  are  no  greater  than  those  offered  to  non-
executive participants. The plan is funded through cash contributions made by the Company based on actuarial 
valuations and regulatory requirements. Employees working for the Company in the U.S. are fully vested after 
completing five years of eligible employment. Employees earn the right to receive a benefit upon retirement at 
the  normal  retirement  age  of  65  or  upon  early  retirement  (age  55  or  older  with  five  years  of  service). 
Furthermore, employees earn the right to receive a benefit if they are active employees and age 65 or older 
(with five years of service). 

The  elements  of  compensation  included  in  computing  the  retirement  benefit  are  basic  salary  and  annual 
performance bonuses earned prior to January 1, 2015. Retirement benefits are calculated as (i) the sum of 1% 
of the employee’s compensation for each calendar year (or partial year) of employment, divided by (ii) twelve. 

Certain  assumptions  and  calculation  methods  were  used  to  determine  the  values  of  the  pension  benefits 
disclosed  in  the  “Pension  Benefits  for  2018”  table  above.  In  particular,  monthly  accrued  pension  benefits, 
payable  at  age  65,  were  determined  as  of  December 31,  2018.  The  present  value  of  these  benefits  was 
calculated based on assumptions used in the Company’s financial statements for 2018.   

Transocean Pension Equalization Plan 

The  Pension  Equalization  Plan  (“PEP”)  is  a  nonqualified,  unfunded,  noncontributory  pension  plan  that  was 
frozen effective December 31, 2014. Messrs. Adamson and Stobart are the only Named Executive Officers with 
a frozen benefit in the PEP. 

Certain employees are eligible to receive a benefit under the PEP if the level of their compensation prior to 
January 1, 2015, would otherwise cause them to exceed the Internal Revenue Code compensation limitations 
imposed on the Transocean U.S. Retirement Plan. The purpose of the PEP is to provide supplemental post-
retirement  income  in  recognition  of  service  to  the  Company.  Benefits  are  payable  upon  a  participant’s 
termination of employment, or six months after termination in the case of certain officers.   

The plan recognizes the same forms of compensation and the same formula used to calculate the plan benefit 
as the Transocean U.S. Retirement Plan however, earnings are not limited to the pay cap under the Internal 
Revenue Code Section 401(a)(17) (U.S. $260,000 in 2014 when the PEP was frozen). Benefits are not earned 
until the individual has five years of credited service with the Company.   

Certain  assumptions  and  calculation  methods  were  used  to  determine  the  values  of  the  pension  benefits 
disclosed  in  the  “Pension  Benefits  for  2018”  table  above.  In  particular,  monthly  accrued  pension  benefits, 
payable  at  age  65,  were  determined  as  of  December 31,  2018.  The  present  value  of  these  benefits  was 
calculated based on assumptions used in the Company’s financial statements for 2018.

CEO Pay Ratio 

Pursuant to the Securities Exchange Act of 1934, as amended, the Company is required to disclose in this 
proxy statement the ratio of the total annual compensation of our CEO to the total annual compensation of our 
median employee. 

Based  on  SEC  rules  for  this  disclosure  and  applying  the  methodology  described  below,  the  Company 
determined that our CEO’s total compensation in U.S. dollars for 2018 was $8,550,795, and the 2018 total 
compensation  of  the  median  employee  in  U.S.  dollars  was  $118,192.  Accordingly,  for  2018,  the  Company 
estimates the ratio of our CEO’s total compensation to the median total compensation of all employees to be 
72 to 1. 

Due to acquisitions that occurred in 2018 that impacted our employee population, we are not using the same 
median employee as prior year. In determining the applicable median salary, we first excluded 209 of our non-
U.S. employees located in Angola, Cyprus, Hungary, Malaysia, India, Cayman Islands, Nigeria, Singapore and 
Thailand representing 4.2% of our workforce, a de minimis number of non-US employees as allowed under the 
SEC rules. Next, for all other non-U.S. employees paid in local non-U.S. currency, salaries were denominated 
in U.S. dollars by applying applicable currency exchange rates in place on December 31, 2018. This currency 
exchange  was  necessary  for  comparison  to  our  CEO  pay  which  is  denominated  in  U.S.  dollars.  We  then 
identified the median employee based on a tabulation of annualized base salary for all included employees on 
December 31, 2018, the last day of our fiscal year.   

Once the median employee was identified as described above, the total annual compensation for 2018 for that 
employee was determined using the same rules that apply to reporting NEO compensation in the Total column 
of the “Summary Compensation Table.”

The  members  of  the  Compensation  Committee  of  the  Board  of  Directors  during  2018  were  Tan  Ek  Kia, 
Chairman, Frederico F. Curado, and Vincent J. Intrieri. There are no matters relating to interlocks or insider 
participation that we are required to report. 

Section 16(a) Beneficial Ownership Reporting Compliance 

Federal securities laws require the Company’s Executive Officers and directors, and persons who own more 
than  ten percent  of  the  Company’s  shares,  to  file  initial  reports  of  ownership  and  reports  of  changes  in 
ownership of the Company’s equity securities with the SEC. Based solely on a review of such reports furnished 
to the Company and written representations that no report on Form 5 was required for 2018, the Company 
believes that no director, officer or beneficial owner of more than ten percent of the Company’s shares failed to 
file a report on a timely basis in 2018. 

Householding 

The  SEC  permits  us,  under  certain  circumstances,  to  send  a  single  set  of  the  Notice,  proxy  materials,  and 
annual reports to any household at which two or more shareholders reside if they appear to be members of the 
same  family.  This  procedure,  referred  to  as  householding,  reduces  the  volume  of  duplicate  information 
shareholders receive and reduces mailing and printing expenses. 

In order to take advantage of this opportunity, we have delivered only one copy of the Notice or, if you previously 
requested to receive paper proxy materials by mail, one proxy statement and annual report to shareholders 
who share an address (unless we received contrary instructions from one or more of the affected shareholders 
prior to the mailing date). However, if any such shareholder residing at such an address wishes to receive a 
separate copy of any of these documents either now or in the future, or if any such shareholder who elected to 
continue to receive separate copies wishes to receive a single copy in the future, that shareholder should send 
a request in writing to Investor Relations at our offices in the United States, at 4 Greenway Plaza, Houston, 
Texas 77046 or by calling +1 (713) 232-7500. We will deliver, promptly upon written or oral request to Investor 
Relations, a separate copy of the Notice, proxy materials or annual report, as applicable, to a shareholder at a 
shared address to which a single copy of the documents was delivered. 

A number of brokerage firms have instituted householding. If your family or others with a shared address have 
one  or  more  “street  name”  accounts  under  which  you  beneficially  own  shares,  you  may  have  received 
householding  information  from  your  broker/dealer,  financial  institution  or  other  nominee  in  the  past.  Please 
contact the holder of record directly if you have questions, require additional copies of the proxy materials or 
wish to revoke your decision to household and thereby receive multiple copies. 

Proposals of Shareholders 

Shareholder  Proposals  in  the  Proxy  Statement.  Rule  14a-8  under  the  Exchange  Act  addresses  when  a 
company must include a shareholder’s proposal in its proxy statement and identify the proposal in its form of 
proxy when the company holds an annual or special meeting of shareholders. Under Rule 14a-8, in order for 
your proposals to be considered for inclusion in the proxy statement and proxy card relating to our 2020 Annual 
General  Meeting,  your  proposals  must  be  received  at  our  principal  executive  offices  c/o  Transocean 
Management Ltd., Turmstrasse 30, CH-6312 Steinhausen, Switzerland by no later than 5:00 p.m. Swiss time 
on November 9, 2019. However, if the date of the 2020 Annual General Meeting changes by more than 30 
days from the anniversary of the 2019 Annual General Meeting, the deadline is a reasonable time before we 
begin to print and mail our proxy materials. We will notify you of this deadline in a Quarterly Report on Form 
10-Q, in a Current Report on Form 8-K or in another communication to you. Shareholder proposals must also 
be otherwise eligible for inclusion.

OTHER MATTERS 

Shareholder Proposals and Nominations for Directors to be Presented at Meetings. If you desire to bring a 
matter before an annual general meeting and the proposal is submitted outside the process of Rule 14a-8, you 
must follow the procedures set forth in our Articles of Association. Our Articles of Association provide generally 
that,  if  you  desire  to  propose  any  business  at  an  annual  general  meeting  (including  the  nomination  of  any 
director), you must give us written notice at least 30 calendar days prior to the anniversary date of the proxy 
statement in connection with Transocean’s last annual general meeting; provided, however, that if the date of 
the annual general meeting is 30 calendar days before or after the anniversary date of the last annual general 
meeting, such request must instead be made by the tenth day following the date on which we have made public 
disclosure  of  the  date  of  the  annual  general  meeting.  The  deadline  under  our  Articles  of  Association  for 
submitting proposals will be 5:00 p.m. Swiss time on February 7, 2020, for the 2020 annual meeting unless it 
is more than 30 calendar days before or after May 9, 2020. 

In order for the notice to be considered timely under Rule 14a-4(c) of the Exchange Act, proposals must be 
received no later than 5:00 p.m. Swiss time on February 7, 2020. The request must specify the relevant agenda 
items and motions, together with evidence of the required shareholdings recorded in the share register, as well 
as any other information required to be included in a proxy statement pursuant to the rules of the SEC. 

If you desire to nominate directors to be presented at an annual general meeting, you must give us written 
notice within the time period described in the preceding paragraph. If you desire to nominate directors to be 
presented at an extraordinary general meeting at which the Board of Directors has determined that directors 
will be elected, you must give us written notice by the close of business on the tenth day following our public 
disclosure of the meeting date. Notice for the nomination of directors at any general meeting must set forth: 

●  Your name and address and the name and address of the person or persons to be nominated; 

●  A representation that you are a holder of record of our shares entitled to vote at the meeting or, if the 
record  date  for  the  meeting  is  subsequent  to  the  date  required  for  that  shareholder  notice,  a 
representation that you are a holder of record at the time of the notice and intend to be a holder of record 
on the date of the meeting and, in either case, setting forth the class and number of shares so held, 
including shares held beneficially; 

●  A representation that you intend to appear in person or by proxy as a holder of record at the meeting to 

nominate the person or persons specified in the notice; 

●  A description of all arrangements or understandings between you and each nominee you propose and 

any other person or persons under which the nomination or nominations are to be made by you; 

●  Any other information regarding each nominee you propose that would be required to be included in a 

proxy statement filed pursuant to the proxy rules of the SEC; and 

●  The consent of each nominee to serve as a director if so elected. 

The Board of Directors may refuse to transact any business you propose or to acknowledge your nomination 
of any person if you fail to comply with the foregoing procedures. You may obtain  a copy of  our  Articles  of 
Association and Organizational Regulations, in which these procedures are set forth, upon written request to 
our Corporate Secretary, Transocean Ltd., Turmstrasse 30, CH-6312 Steinhausen, Switzerland. 

Cost of Solicitation 

The accompanying proxy is being solicited on behalf of the Board of Directors. The expenses of preparing, 
printing and mailing the proxy and the materials used in the solicitation will be borne by us. We have retained 
Georgeson LLC for a fee of $20,000, plus expenses, to aid in the solicitation of proxies. Proxies may be solicited 
by  personal  interview,  mail,  telephone,  facsimile,  internet  or  other  means  of  electronic  distribution  by  our 
directors,  officers  and  employees,  who  will  not  receive  additional  compensation  for  those  services. 
Arrangements also may be made with brokerage houses and other custodians, nominees and fiduciaries for 
the forwarding of solicitation materials to the beneficial owners of shares held by those persons, and we will 
reimburse  them  for  reasonable  expenses  incurred  by  them  in  connection  with  the  forwarding  of  solicitation 
materials.

OTHER MATTERS 

Forward-Looking Statements 

The statements included in this proxy statement, including in the letter to shareholders and in the section entitled 
“Compensation  Discussion  and  Analysis—Executive  Summary—2018  Business Overview,”  regarding  future 
financial performance, results of operations, liquidity, stacking of assets and the market and other statements 
that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities 
Act of 1933 and Section 21E of the Exchange Act. Forward-looking statements are subject to numerous risks, 
uncertainties and assumptions, including, but not limited to, the future prices of oil and gas, operating hazards 
and delays, actions by customers and other third parties, conditions in the drilling industry and in the capital 
markets and those described under “Item 1A. Risk Factors” in the 2018 Annual Report and in our other filings 
with the SEC. Should one or more of these risks or uncertainties materialize (or the other consequences of 
such  a  development  worsen),  or  should  underlying  assumptions  prove  incorrect,  actual  results  may  vary 
materially from those indicated or expressed or implied by such forward-looking statements. All subsequent 
written and oral forward-looking statements attributable to us or to persons acting on our behalf are expressly 
qualified in their entirety by reference to these risks and uncertainties. You should not place undue reliance on 
forward-looking  statements.  Each  forward-looking  statement  speaks  only  as  of  the  date  of  the  particular 
statement, and we undertake no obligation to publicly update or revise any forward-looking statements, except 
as required by law.

To the General Meeting of  

Transocean Ltd., Steinhausen  

Zurich, March 8, 2019 

Report of the statutory auditor on the compensation report 

We have audited the compensation report (pages CR-2 to CR-6) of Transocean Ltd. for the year ended December 31, 2018. 

Board of Directors’ responsibility 
The Board of Directors is responsible for the preparation and overall fair presentation of the compensation report in accordance with Swiss 
law and the Ordinance against Excessive Compensation in Stock Exchange Listed Companies (Ordinance).  The Board of Directors is also 
responsible for designing the compensation system and defining individual compensation packages. 

Auditor’s Responsibility 
Our responsibility is to express an opinion on the compensation report.  We conducted our audit in accordance with Swiss Auditing Standards.  
Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about 
whether the compensation report complies with Swiss law and articles 14 – 16 of the Ordinance. 

An  audit  involves  performing  procedures  to  obtain  audit  evidence  on  the  disclosures  made  in  the  compensation  report  with  regard  to 
compensation, loans and credits in accordance with articles 14 – 16 of the Ordinance.  The procedures selected depend on the auditor’s 
judgment, including the assessment of the risks of material misstatements in the compensation report, whether due to fraud or error.  This 
audit also includes evaluating the reasonableness of the methods applied to value components of compensation, as well as assessing the 
overall presentation of the compensation report. 

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 

Opinion 
In  our  opinion,  the  compensation  report  for  the  year  ended  December 31,  2018  of  Transocean Ltd.  complies  with  Swiss  law  and 
articles 14 – 16 of the Ordinance.

This  Compensation  Report  reflects  the  requirements  of  Articles 13–16  of  the  Swiss  Federal  Ordinance  Against  Excessive

In  addition  to  the  directors’  compensation,  we  pay  or  reimburse  our  directors  for  travel  and  incidental  expenses  incurred  for 
attending  board,  committee  and  shareholder  meetings  and  for  other  company-related  business  purposes.    Our  directors  who  are  our 
employees do not receive compensation for board service.  With the exception of Jeremy D. Thigpen, all of the directors on our Board of 
Directors receive compensation as non-employees.  No director served in the position of non-executive vice chairman for the years ended 
December 31, 2018 and December 31, 2017. 

We grant restricted share units to the non-executive chairman and each non-employee director annually with an aggregate value 
of USD 325,000 and USD 210,000, respectively, based upon the average of the high and low market prices of our shares for each of the 
10 trading days preceding the date of grant.  The restricted share units vest on the date first to occur of (i) the first anniversary of the date of 
grant or (ii) the Annual General Meeting next following the date of grant, subject to continued service through the vesting date.  Vesting of 
the restricted share units is not subject to any performance measures.  Each director may elect to receive the shares upon vesting or to defer 
shares until the director no longer serves on the board.

COMPENSATION REPORT—continued 

Share-based  compensation—We  granted  to  the  members  of  our  Executive  Management  Team  share-based  compensation 
awards under our long-term incentive plans.  As presented below, total share-based compensation represents the fair value of grants made 
to the members of our Executive Management Team and does not represent actual income earned.  Any income earned from subsequent 
vesting of the awards will be subject to employer-paid social taxes at the statutory rate prevailing at the time income is earned. 

To measure the fair values of stock options granted or modified, we use the Black-Scholes-Merton option-pricing model and apply 
assumptions for the expected life, risk-free interest rate, dividend yield and expected volatility.  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 performance share units that are subject to market factors, such as total shareholder return, we use a 
Monte Carlo simulation model  and, in addition  to the assumptions applied for the Black-Scholes-Merton option-pricing model, we apply 
assumptions using a risk neutral approach and the average price at the performance start date. 

In the years ended December 31, 2018 and 2017, we granted performance share units to members of our Executive Management 
Team.    Such  performance  share  units  are  subject  to  a  three-year  performance  period  during  which  the  actual  number  of  units  remain 
uncertain.  The number of performance share units presented below represents the targeted number of shares awarded.  The actual number 
of share units earned will be determined in the first 60 days following the performance period based on performance thresholds and may 
range between zero and two shares per performance share unit. 

Share-based compensation awards were granted as follows:

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 11, 2019, we owned or had partial ownership interests in and operated a fleet of 49 mobile offshore drilling units, consisting of 
31 ultra-deepwater  floaters,  14 harsh  environment  floaters  and  four midwater  floaters.    As  of  February 11,  2019,  we  were  constructing 
(i) four additional  ultra-deepwater  drillships  and  (ii) one additional  harsh  environment  semisubmersible,  in  which  we  hold  a  partial 
ownership interest. 

Our primary business is to contract our drilling rigs, related equipment and work crews predominantly on a dayrate basis 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 mobile offshore drilling fleet is one of the most versatile fleets in the world, 
consisting  of  drillship  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 Zug, Switzerland.  Our telephone number at that address is +41 41 749-0500.  Our shares are 
listed on the New York Stock Exchange under the 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 20—Operating Segments, Geographic Analysis and Major Customers.” 

Recent Developments 

Business  combinations—On  January 30,  2018,  we  acquired  an  approximate  97.7 percent  ownership  interest  in  Songa 
Offshore  SE,  a  European  public  company  limited  by  shares,  or  societas  Europaea,  existing  under  the  laws  of  Cyprus  (“Songa”).    On 
March 28, 2018, we acquired the remaining shares not owned by us through a compulsory acquisition under Cyprus law, and as a result, 
Songa became our wholly owned subsidiary.  To complete these transactions, we issued 68.0 million shares and $863 million aggregate 
principal amount of 0.50% exchangeable senior bonds due January 30, 2023.  As a result of the acquisition, we acquired seven mobile 
offshore drilling units, including five harsh environment floaters and two midwater floaters. 

On  December 5,  2018,  we  acquired  Ocean Rig  UDW Inc.  (“Ocean Rig”),  a  Cayman  Islands  exempted  company  with  limited 
liability, in a merger transaction, and as a result, Ocean Rig became our wholly owned subsidiary.  To complete the acquisition, we issued 
147.7 million shares and made an aggregate cash payment of $1.2 billion.  As a result of the acquisition, we acquired (i) 11 mobile offshore 
drilling units, including nine ultra-deepwater floaters and two harsh environment floaters, and (ii) the contracts relating to the construction of 
two ultra-deepwater  drillships.    In  February 2019,  we  committed  to  plans  to  sell  one ultra-deepwater  floater  and  one harsh  environment 
floater acquired in the Ocean Rig acquisition.

Drilling Fleet 

Fleet overview—Our drilling fleet of floaters consists of drillships and semisubmersibles, which are mobile and can be moved to 
new locations in response to customer demand.  Our drilling equipment is suitable for both exploration and development, and we engage 
in both types of drilling activity.  Our mobile offshore drilling units 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. 

Drillships are generally self-propelled vessels, shaped like conventional ships, and are the most mobile of the major rig types.  
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.  Ultra-deepwater drillships typically have greater deck load 
and storage capacity than early generation 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.  We have 25 ultra-deepwater drillships that are, and four 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 to dynamic positioning 
thruster systems, dual-activity technology and industry-leading hoisting capacity, one of our newbuild drillships under construction, which 
was  recently  contracted,  will  be  equipped  with  and  another  newbuild  drillship  will  be  equipped  to  accommodate  two 20,000 pounds  per 
square inch (“psi”) blowout preventers. 

AR-2 

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.    Five of  our 
22 semisubmersibles are equipped with dual-activity technology and also have mooring capability.  Two of these five dual-activity units are 
custom-designed, high capacity semisubmersible drilling rigs, equipped for year-round operations in harsh environments, including those 
of the Norwegian continental shelf and sub-Arctic waters. 

Fleet  categories—We  further  categorize  the  drilling  units  of  our  fleet  as  follows:  (1) “ultra-deepwater  floaters,”  (2) “harsh 
environment floaters” and (3) “midwater floaters”.  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.    Midwater  floaters  are  generally  comprised  of  those  non-high-specification  semisubmersibles  that  have  a 
water depth capacity of less than 4,500 feet. 

As of February 11, 2019, we owned and operated a fleet of 49 rigs, excluding five newbuilds under construction, as follows: 
 
 
 

31 ultra-deepwater floaters; 
14 harsh environment floaters; and 
Four midwater floaters.  

Fleet  status—Depending  on  market  conditions,  we  may  idle  or  stack  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 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 significant 
and could fluctuate over time, depends upon various factors, including the availability and cost of shipyard facilities, the cost of equipment 
and materials and the extent of repairs and maintenance that may ultimately be required.  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 11,  2019,  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 11, 2019, we owned all of the drilling rigs in our fleet 
noted in the tables below, except for the following: (1) the harsh environment floater Transocean Norge, which is under construction and 
owned  through  our  33.0 percent  ownership  interest  in  Orion  Holdings  (Cayman) Limited,  and  (2) the  ultra-deepwater  floater 
Petrobras 10000, which is subject to a capital lease through August 2029.

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 are able to 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 demand in another locale.  Consequently, we cannot predict the percentage of our revenues that will be derived 
from particular geographic areas in future periods.  As of February 11, 2019, our drilling fleet, including stacked and idle rigs, but excluding 
rigs  under  construction,  was  located  in  the  Norwegian North Sea (nine units),  the  United  States  (“U.S.”) Gulf of Mexico (seven units), 
Trinidad (six units),  Greece (five units),  United  Kingdom 
(“U.K.”) North Sea (five units),  Angola (two units),  Canada (two units), 
India (two units),  Spain (two units),  Australia (one unit),  Brazil (one unit),  Brunei (one unit),  China (one unit),  Equatorial Guinea (one unit), 
Ivory Coast (one unit), Malaysia (one unit), Mexican Gulf of Mexico (one unit) and Romania (one unit). 

We categorize the market sectors in which we operate as follows: (1) ultra-deepwater and deepwater, (2) harsh environment and 
(3) midwater.  These market sectors, collectively known as the floater market, are serviced by our drillships and semisubmersibles, 14 of 
which are suited to work in harsh environments.  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  services  water  depths  from  approximately  300 feet  to  approximately  4,500 feet.    The  harsh 
environment  market  sector  services  regions  that  are  more  challenged  by  lower  temperatures,  harsher  weather  conditions  and  water 
currents. 

The market for offshore drilling  rigs and related services reflects oil companies’ demand for equipment for drilling exploration, 
appraisal  and  development  wells  and  for  performing  maintenance  on  existing  production  wells.    Activity  levels  of  exploration  and 
production (“E&P”) companies and their associated capital expenditures 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 E&P companies’ 
ability to fund investments in exploration, development and production activities. 

In  recent  years,  the  industry  has  experienced  a  severe,  prolonged  cyclical  downturn.    Multiple  years  of  volatile  and  generally 
weak commodity prices have resulted in our customers delaying offshore investment decisions and postponing exploration and production 
programs.    Structural  efficiency  gains  implemented  by  industry  participants  in  reaction  to  the  downturn  have  given  customers  more 
flexibility to progress exploration and development plans in a lower commodity pricing environment, which resulted in increased customer 
project  sanctioning  in  2018.    We  anticipate  this  trend  of  increased  project  sanctioning  to  continue  in  2019  as  our  customers  realize 
improved  offshore  economics,  making  them  less  sensitive  to  market  volatility,  and  sharpening  their  focus  on  exploration  and  reserve 
replacement.    In  markets  requiring  harsh  environment  floating  drilling  rigs,  such  as  the  Norwegian North Sea  and  eastern  Canada,  the 
limited supply of these specialized rigs has resulted in improved fleet utilization, which has caused increased dayrates on high-specification 
rigs  being  tendered  for  new  work  over  the  past  year.    Outside  of  harsh  environment  markets,  however,  persistent  excess  supply  of 
ultra-deepwater floaters relative to demand has delayed improvement of dayrates.  As the hydrocarbon supply-demand balance improves, 
we expect sustained improvement of oil prices, ultimately resulting in greater demand for ultra-deepwater drilling rigs and improvement of 
dayrates. 

Our recent acquisitions of Songa and Ocean Rig have significantly enhanced our high-specification asset portfolio.  The Songa 
acquisition improved our fleet profile with harsh environment units for which we have already seen improved demand.  The Ocean Rig 
acquisition further improved our fleet profile by adding high-specification ultra-deepwater units that we expect to be in high demand as the 
market  improves  and  the  offshore  drilling  industry  continues  to  prioritize  the  most  modern  and  capable  assets.    We  have  also  made 
concerted efforts since the beginning of the downturn to high-grade our fleet through divestment of lower-specification assets.  During the 
years  ended  December 31,  2018,  2017  and  2016,  we  sold  for  scrap  value  eight,  three and  11 drilling  units,  respectively,  and  at 
December 31, 2018, we had five additional rigs classified as held for sale for scrap value. 

Longer term, our outlook for the offshore drilling sector remains positive, particularly for high-specification assets.  Prior to the 
downturn,  Brazil,  the  U.S. Gulf of Mexico,  and  West Africa  emerged  as  key  ultra-deepwater  market  sectors,  and  licensing  activity 
demonstrated an increased interest in deepwater fields as E&P companies looked to explore new prospects.  We expect deepwater oil and 
gas production will continue to be a part of the long-term strategy for E&P companies as they strive to replace reserves to meet global 
demand for hydrocarbons.  As our customers implement the structural efficiency gains, we anticipate additional projects will be approved.  
Typically, these projects are technically demanding due to factors such as water depth, complex well designs, deeper drilling depth, high 
pressure and temperature, sub-salt, harsh environments, and heightened regulatory standards; therefore, they require sophisticated drilling 
units.  Generally, ultra-deepwater rigs are the most modern, technologically advanced class of the offshore fleet and have capabilities that 
are attractive to E&P companies operating in deeper water depths, other challenging environments or with complex well designs.   See 
“Item 1A. Risk Factors—Risks related to our business.” 

Contract Drilling Services 

Our contracts to provide offshore drilling services are individually negotiated and vary in their terms and conditions.  We obtain 
most of our drilling contracts through competitive bidding against other contractors and direct negotiations with operators.  Drilling contracts 
generally  provide  for  payment  on  a  dayrate  basis,  with  higher  rates  for  periods  while  the  drilling  unit  is  operating  and  lower  rates  or 

AR-5 

zero rate  for  periods  of  mobilization  or  when  drilling  operations  are  interrupted  or  restricted  by  equipment  breakdowns,  adverse 
environmental  conditions  or  other  conditions  beyond  our  control.    A  dayrate  drilling  contract  generally  extends  over  a  period  of  time 
covering either the drilling of a single well or group of wells or covering a stated term.  At December 31, 2018, our contract backlog was 
approximately $12.5 billion, representing an increase of 32 percent and seven percent, respectively, compared to the contract backlog at 
December 31, 2017 and 2016, which was $9.5 billion and $11.7 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 upon payment of an early termination 
payment.  Such payments, however, may not fully compensate us for the loss of the contract.  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, in the event of extended downtime or impaired performance caused by equipment or operational 
issues, or periods of 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  an  additional  term.    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  firm  drilling  contracts  to  reduce  the  term  of  their 
obligations or the average dayrate through term extensions, or may seek to repudiate their contracts.  Suspension of drilling contracts will 
result in the reduction in or loss of dayrate for the period of the suspension.  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, if contracts are suspended for an extended period of 
time or if a number of our contracts are renegotiated, it could adversely affect our consolidated financial position, results of operations or 
cash  flows.    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,  our  drilling 
contracts are individually negotiated, and the degree of indemnification we receive from our customers for the risks discussed above may 
vary from contract to contract, based on market conditions and customer requirements existing when the contract was negotiated.  In some 
instances,  we  have  contractually  agreed  upon  certain  limits  to  our  indemnification  rights  and  can  be  responsible  for  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.  In most instances in which we are indemnified for damages to the well, we have the responsibility to redrill the well at a 
reduced  dayrate.    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.  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.” 

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  will  need  to  consider  the 
specific  contract  language,  the  facts  and  applicable  laws.    The  law  generally  considers  contractual  indemnity  for  criminal  fines  and 
penalties to be against public policy.  Courts also restrict indemnification for criminal fines and penalties.  The inability or other failure of our 
customers to fulfill their indemnification obligations, or unenforceability of our contractual protections could have a material adverse effect 
on our consolidated financial position, results of operations or cash flows. 

Significant Customers 

We engage in offshore drilling services for most of the leading integrated oil companies or their affiliates, as well as for many 
government-controlled  oil  companies  and  independent  oil  companies.    For  the  year  ended  December 31,  2018,  our  most  significant 
customers were Royal Dutch Shell plc (together with its affiliates, “Shell”), Chevron Corporation (together with its affiliates, “Chevron”) and 
Equinor ASA (together with its affiliates, “Equinor”), representing approximately 26 percent, 21 percent and 18 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,  2018.    Additionally,  as  of  February 11,  2019,  the  customers  with  the  most  significant  aggregate  amount  of 
contract  backlog  associated  with  our  drilling  contracts  were  Shell,  Equinor  and  Chevron,  representing  approximately  45 percent, 
28 percent and 15 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 consolidated financial position, results of operations or cash flows.” 

Employees 

We  require  highly  skilled  personnel  to  operate  our  drilling  units.    Consequently,  we  conduct  extensive  personnel  recruiting, 
training  and  safety  programs.    At  December 31,  2018,  we  had  approximately  6,700 employees,  including  approximately  800 persons 
engaged through contract labor providers.  Approximately 34 percent of our total workforce, working primarily in Norway, Brazil, the U.K. 

AR-6 

and Australia 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.  These negotiations could result in higher personnel expenses, other increased costs or 
increased  operational  restrictions,  as  the  outcome  of  such  negotiations  affect  the  market  for  all  offshore  employees  not  just  the  union 
members.  Additionally, failure to reach agreement on certain key issues may result in strikes, lockouts or other work stoppages that may 
materially impact our operations. 

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 enter into agency or sponsorship agreements.  We may also enter into joint ventures for 
operational or investment purposes.  We may or may not control these joint ventures.  We participate in several joint venture companies, 
principally  in  the  Cayman  Islands,  Angola,  Indonesia,  Malaysia  and  Nigeria.    At  December 31,  2018,  we  held  interests  in  certain  joint 
venture companies in the Cayman Islands, Angola, Indonesia, Malaysia, Nigeria and other countries, the most significant of which were as 
follows: 

We hold a 33.0 percent ownership interest in Orion Holdings (Cayman) Limited, an unconsolidated Cayman Islands exempted 
company  formed  to  construct  and  own  the  newbuild  harsh  environment  semisubmersible  Transocean Norge.    Our  partners,  certain 
affiliates of Hayfin Capital Management LLP, own the remaining 67.0 percent ownership interest not owned by us. 

We hold a 24 percent direct interest and a 36 percent indirect interest in Indigo Drilling Limited (“Indigo”), a consolidated Nigerian 
joint  venture  company  formed  to  engage  in  drilling  operations  offshore  Nigeria.    Our  local  partners,  Mr. Fidelis Oditah  and 
Mr. Chima Ibeneche, each hold a 12.5 percent direct interest, and our other partners, Mr. Joseph Obi and Mr. Ben Osuno, together own a 
15 percent indirect interest in Indigo. 

Technological Innovation 

Since  launching  the  offshore  industry’s  first jackup  drilling  rig  in  1954,  we  have  achieved  a  long  history  of  technological 
innovations,  including  the  first dynamically  positioned  drillship,  the  first rig  to  drill  year-round  in  the  North  Sea,  the  first  10,000-ft.  rated 
ultra-deepwater drillship and the first semisubmersible rig for year-round sub-Arctic operations.  We have repeatedly achieved water depth 
world records in the past.  Twenty-five drillships and three semisubmersibles in our existing fleet are, and our four drillships that are under 
construction will be, equipped with our patented dual-activity technology, and two of our semisubmersibles are equipped with another form 
of dual-activity technology.  Dual-activity allows our rigs to perform simultaneous drilling tasks in a parallel rather than sequential manner 
and reduces critical path activity while improving efficiency in both exploration and development drilling. 

We  continue  to  develop  and  deploy  industry-leading  technology.    In  addition  to  our  patented  dual-activity  drilling  technology, 
two of  our  drillships  under  construction  will  include  industry-leading  hookload  capability,  hybrid  power  systems  for  reduced  fuel 
consumption  and  reduced  emissions  as  well  as  advanced  generator  protection  for  power  plant  reliability.    We  are  focused  on  a 
breakthrough drilling innovation program that includes a fault-resistant and fault-tolerant blowout preventer control system.  Nine drillships 
in our existing fleet are, and our four drillships that are under construction will be, outfitted with two blowout preventers and triple liquid mud 
systems.  Five drillships in our existing fleet are, and two of our drillships that are under construction will be, designed to accept 20,000 psi 
blowout preventers in the future, and we recently contracted one of the drillships under construction to be equipped as such.  Seven of our 
harsh environment semi-submersibles are designed and constructed specifically to provide highly efficient performance in the Norwegian 
North  Sea  and  in  the  Barents Sea.    We  believe  the  continual  improvement  of,  and  effective  use  of,  technology  to  meet  or  exceed  our 
customers’ requirements is critical to maintain our competitive position within the contract drilling services industry.  Additionally, our digital 
transformation  program  delivers  real-time  data  feeds  from  equipment  and  processes,  which  is  used  to  build  machine  health  models.  
These  models  allow  us  to  systematically  optimize  equipment  maintenance  and  achieve  higher  levels  of  operational  efficiency.    This 
data-driven approach, augmented by the size of our fleet, is helping us build a knowledge framework for sustainable process optimization. 

Environmental Compliance 

Our  operations  are  subject  to  a  variety  of  global  environmental  regulations.    We  monitor  our  compliance  with  environmental 
regulation in each country of operation and, while we see an increase in general environmental regulation, we have made and will continue 
to make the required expenditures to comply with current and future environmental requirements.  We make expenditures to further our 
commitment to environmental improvement and the setting of global environmental standards.  We assess the environmental impacts of 
our business, focusing on the areas of greenhouse gas emissions, climate change, discharges and waste management.  Our actions are 
designed  to  reduce  risk  in  our  current  and  future  operations,  to  promote  sound  environmental  management  and  to  create  a  proactive 
environmental program.  To date, we have not incurred material costs in order to comply with recent environmental legislation, and 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.  For a discussion of the effects of environmental regulation, see “Item 1A. Risk Factors—Risks related to our 
business—Compliance with or breach of environmental laws can be costly, expose us to liability and could limit our operations.”

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  the  level  of  activity  in  oil  and  gas  exploration,  development  and  production  in  offshore  areas 
worldwide.  Demand for our services depends on oil and natural gas industry activity and 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. and other large energy-consuming markets; 
the  ability  of  the  Organization  of  the  Petroleum  Exporting  Countries  (“OPEC”)  to  set  and  maintain  production  levels,  productive  spare 
capacity and pricing; 
the level of production in non-OPEC countries; 
the policies of various governments regarding exploration and development of their oil and gas reserves; 
international sanctions on oil-producing countries, or the lifting of such sanctions; 
advances in exploration, development and production technology; 
the further development of shale technology to exploit oil and gas reserves; 
the discovery rate of new oil and gas reserves; 
the rate of decline of existing oil and gas reserves; 
laws  and  regulations  related  to  environmental  matters,  including  those  addressing  alternative  energy  sources  and  the  risks  of  global 
climate change; 
the development and exploitation of alternative fuels; 
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 or other crises in the Middle East or other geographic areas or acts of terrorism.

Demand  for  our  services  is  particularly  sensitive  to  the  level  of  exploration,  development  and  production  activity  of,  and  the 
corresponding  capital  spending  by,  oil  and  natural  gas  companies,  including  national  oil  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 oil and gas companies could similarly reduce or defer major expenditures given the long-term nature of 
many large-scale development projects.  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 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, 

AR-8 

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  have  responded  to  increased  customer  demand  by  increasing  the  supply  of  rigs  through  ordering  the 
construction of new units.  The number of new units expected to be delivered without contracts, combined with the expected increase in 
the number of rigs in the global market completing contracts and becoming idle, has intensified and may further intensify price competition.  
In  periods  of  low  oil  and  natural  gas  price  levels,  new  construction  has  historically  resulted  in  an  oversupply  of  rigs  and  has  caused  a 
subsequent decline in dayrates and rig utilization rates, sometimes for extended periods of time.  Any further near-term increase in the 
construction of new units would likely exacerbate the negative impact of increased supply on dayrates and rig utilization rates.  Additional 
rigs that remain under construction, and the entry into service of these new units will increase overall supply.  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 lower dayrates in exchange for longer contract terms.  Lower 
dayrates and rig utilization rates could adversely affect our revenues and profitability. 

As of February 11, 2019, we have 19 uncontracted rigs, including seven uncontracted rigs recently acquired in the Ocean Rig 
acquisition.  These rigs may remain out of service for extended periods of time.  We also have three additional rigs under construction that 
have  not  been  contracted  for  work.    If  we  are  unable  to  obtain  drilling  contracts  for  our  uncontracted  rigs,  whether  due  to  a  prolonged 
offshore drilling market recovery or otherwise, it may have an adverse effect on our results of operations and cash flows, and we may not 
be able to realize the expected synergies and other benefits of the acquisition on the timeline currently expected or at all. 

  Our current backlog of contract drilling revenue may not be fully realized. 

At  February 11,  2019,  our  contract  backlog  was  approximately  $12.2 billion.    This  amount  represents  the  number  of  days 
remaining  in  the  firm  term  of  the  drilling  contract  multiplied  by  the  maximum  contractual  operating  dayrate,  excluding  revenues  for 
mobilization, demobilization and contract preparation or other incentive provisions, which are generally insignificant to our contract drilling 
revenues.    Our  contract  backlog  includes  amounts  associated  with  our  newbuild  units  that  are  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 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 a material adverse effect on our 
consolidated financial position, results of operations or 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 or our uncontracted newbuilds. 

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 at the time of 
expiration.  As of February 11, 2019, we have 19 stacked or idle rigs and three ultra-deepwater drillships under construction that do not 
have customer drilling contracts.  We also have nine existing drilling contracts for our rigs that are currently operating, which are scheduled 
to  expire  before  December 31,  2019.    We  may  be  unable  to  obtain  drilling  contracts  for  our  rigs  that  are  currently  operating  upon  the 
expiration or termination of such contracts or obtain drilling contracts for our newbuilds, 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 in direct continuation with existing contracts or for our uncontracted newbuild units, 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 consolidated financial position, results of operations or cash 
flows. 

  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.    Drilling  contracts  also 

AR-9 

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 these events are 
beyond  our  control.    During  periods  of  depressed  market  conditions,  we  are  subject  to  an  increased  risk  of  our  customers  seeking  to 
repudiate  their  contracts,  including  through  claims  of  non-performance.    We  are  at  continued  risk  of  experiencing  early  contract 
terminations  in  a  weak  commodity  price  environment  as  operators  look  to  reduce  their  capital  expenditures.    During  the  years  ended 
December 31,  2017  and  2016,  our  customers  early  terminated  or  cancelled  contracts  for  one and  eight of  our  rigs,  respectively.    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 oil 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,  if  contracts  are  suspended  for  an  extended  period  of  time  or  if  a  number  of  our  contracts  are 
renegotiated,  it  could  adversely  affect  our  consolidated  financial  position,  results  of  operations  or  cash  flows.    See  “Item 1.  Business—
Contract Drilling Services.” 

  We must make substantial capital and operating expenditures to maintain our active fleet or to reactivate our stacked or idle 
fleet,  and  we  may  be  required  to  make  significant  capital  expenditures  to  maintain  our  competitiveness,  to  execute  our 
growth  plan  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 execute our growth plan.  Changes in governmental 
regulations, 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.  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,  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 consolidated financial position, results of operations and cash flows. 

  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,  2018  and  2017,  our  total  debt  was  $10.0 billion  and  $7.4 billion,  respectively,  of  which  $2.6 billion  and 
$1.4 billion, respectively, was 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  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  indentures  governing  certain  of  our  debt  or  in  our  bank  credit  agreements  or  satisfy 
certain other conditions included in our bank credit agreements, which could result in our inability to meet requirements for borrowings 
under our credit agreements or a default under these indentures or 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; 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.

Resources—Sources and uses of liquidity.”

  Various 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. 

Two  credit  rating  agencies  have  rated  our  non-credit  enhanced  senior  unsecured  long-term  debt  (our  “Debt Rating”)  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 or replacing our existing credit 
agreement; 
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 bank credit facilities and interest rates under indentures governing certain of our senior notes; 
reduced willingness of current and prospective customers to transact business with us; 
requirements from creditors 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. 

  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 consolidated financial position, results of operations or cash 
flows. 

We engage in offshore drilling services for most of the leading integrated oil companies or their affiliates, as well as for many 
government-controlled  oil  companies  and  independent  oil  companies.    For  the  year  ended  December 31,  2018,  our  most  significant 
customers were Shell, Chevron and Equinor, accounting for approximately 26 percent, 21 percent and 18 percent, respectively, of our total 
contract drilling revenues.  As of February 11, 2019, the customers with the most significant aggregate amount of contract backlog were 
Shell, Equinor and Chevron, representing approximately 45 percent, 28 percent and 15 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 and on our consolidated financial position, results of operations or cash 
flows. 

In  addition,  our  drilling  contracts  subject  us  to  counterparty  risks.    The  ability  of  each  of  our  counterparties  to  perform  its 
obligations under a contract with us 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.  In addition, in 
depressed market conditions, such as we are currently experiencing, 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.  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  consolidated  financial 
position, results of operations or cash flows. 

  Worldwide financial, economic and political conditions could have a material adverse effect on our consolidated financial 

position, results of operations or cash flows. 

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 current period of low oil and natural gas 
prices.  These potential developments, or market perceptions concerning these and related issues, could affect our consolidated financial 
position, results of operations or cash flows.  In addition, turmoil and hostilities in the Middle East, North Africa and other geographic areas 
and countries are adding to overall 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 a material adverse effect on our consolidated financial position, 
results of operations or 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.  Costs for 
operating  a  rig  are  generally  fixed  or  only  semi-variable  regardless  of  the  dayrate  being  earned.    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 

AR-11 

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. 

  Our shipyard projects and operations are subject to delays and cost overruns. 

As of February 11, 2019, we had under construction four ultra-deepwater drillships and one harsh environment semisubmersible, 
in which we have a partial ownership interest.  We also have a variety of other more limited shipyard projects at any given time.  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: 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

shipyard availability, failures and difficulties; 
shortages of equipment, materials or skilled labor; 
unscheduled delays in the delivery of ordered materials and equipment; 
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; 
failure or delayed deliveries of significant parts or equipment due to supplier shortages, constraints, disruption or quality issues; 
availability of suppliers to recertify equipment for enhanced regulations; 
strikes, labor disputes and work stoppages; 
customer acceptance delays; 
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  our  newbuild  units  and  other  rigs  undergoing 
shipyard projects.  Delayed delivery of these units 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.    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. 

  Compliance with or breach of environmental laws can be costly, expose us to liability and could limit our operations. 

Our  business  in  the  offshore  drilling  industry  is  affected  by  laws  and  regulations  relating  to  the  energy  industry  and  the 
environment, including international conventions and treaties, and regional, national, state, and local laws and regulations.  The offshore 
drilling industry 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  exploration  and 
development drilling for oil and gas.  Compliance with such laws, regulations and standards, where applicable, may require us to make 
significant capital expenditures, such as the installation of costly equipment or 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, 
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 insurance coverage or other financial assurance of our 
ability  to  address  pollution  incidents.    Offshore  drilling  in  certain  areas  has  been  curtailed  and,  in  certain  cases,  prohibited  because  of 
concerns  over  protection  of  the  environment.    These  costs  could  have  a  material  adverse  effect  on  our  consolidated  financial  position, 
results of operations or cash flows.  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. 

AR-12 

To the extent new laws are enacted or other governmental actions are taken that prohibit or restrict offshore drilling or impose 
additional environmental protection 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 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 and production of oil and gas and compliance with any such new legislation or regulations could have an adverse effect on our 
business or on our consolidated financial position, results of operations or cash flows. 

As contract driller with operations in certain offshore areas, we may be liable for damages and costs incurred in connection with 
oil  spills  or  waste  disposals  related  to  those  operations,  and  we  may  also  be  subject  to  significant  fines  in  connection  with  spills.    For 
example,  an  oil  spill  could  result  in  significant  liability,  including  fines,  penalties  and  criminal  liability  and  remediation  costs  for  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  from  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.  Laws and regulations protecting the environment have become more stringent in recent years, 
and may in some cases impose strict liability, 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 a material adverse effect on our consolidated financial position, results of operations or cash flows. 

  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 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. 

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 oil companies and may continue to do so. 

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,  leading  to  an  accumulation  of  excess  local  currency  balances,  which,  in 

AR-13 

certain instances, may be subject to either temporary blocking or other difficulties converting to U.S. dollars, our functional currency, or to 
other currencies in which we operate.  Excess amounts of local currency may be exposed to the risk of currency exchange losses. 

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 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 law. 

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 consolidated financial position, results of operations  or cash 
flows. 

  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 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 South China Sea, the Northwest Coast of Australia and the U.S. Gulf of Mexico 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  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 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 oil and natural gas companies.  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. 

AR-14 

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 consolidated 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. 

  The  continuing  effects  of  the  enhanced  regulations  enacted  following  the  Macondo well  incident  and  of  agreements 

applicable to us could have an adverse effect on our business and worldwide operations. 

Following  the  Macondo  well  incident,  enhanced  governmental  safety  and  environmental  requirements  applicable  to  our 
operations were adopted for drilling in the U.S. Gulf of Mexico.  In order to obtain drilling permits, operators must submit applications that 
demonstrate compliance with the enhanced regulations, which require independent third-party inspections, certification of well design and 
well control equipment and emergency response plans in the event of a blowout, among other requirements.  Operators have had, and 
may in the future have, difficulties obtaining drilling permits in the U.S. Gulf of Mexico.  In addition, the oil and gas industry has adopted 
new equipment and operating standards, such as the American Petroleum Institute Standard 53, related to the installation and testing of 
well  control  equipment.    These  safety  and  environmental  guidelines  and  standards  and  any  new  guidelines  or  standards  the  U.S. 
government or industry may issue or any other steps the U.S. government or industry may take, could disrupt or delay operations, increase 
the  cost  of  operations,  increase  out-of-service  time  or  reduce  the  area  of  operations  for  drilling  rigs  in  the  U.S.  and  non-U.S.  offshore 
areas. 

Other governments could take similar actions related to implementing new safety and environmental regulations in the future.  
Additionally,  some  of  our  customers  have  elected  to  voluntarily  comply  with  some  or  all  the  inspections,  certification  requirements  and 
safety  and  environmental  guidelines  on  rigs  operating  outside  of  the  U.S. Gulf of Mexico.    Additional  governmental  regulations  and 
requirements  concerning  licensing,  taxation,  equipment  specifications  and  training  requirements  or  the  voluntary  adoption  of  such 
requirements or guidelines by our customers could increase the costs of our operations, increase certification and permitting requirements, 
increase review periods and impose increased liability on offshore operations.  The continuing effects of the enhanced regulations may 
also decrease the demand for drilling services, negatively affect dayrates and increase out-of-service time, which could ultimately have an 
adverse effect on our revenues and profitability. 

  Corporate  restructuring  activity,  divestitures,  acquisitions  and  other  business  combinations  and  reorganizations  could 

adversely affect our ability to achieve our strategic goals. 

We  have  undertaken  and  continue  to  seek  appropriate  opportunities  for  restructuring  our  organization,  engaging  in  strategic 
divestitures, acquisitions and other business combinations in order to optimize our fleet and strengthen our competitiveness.  We face risks 
arising from these activities, which could adversely affect our ability to achieve our strategic goals, such as the following: 

 

 

 

 

we may be unable to realize the growth or investment opportunities, improvement of our financial position and other expected benefits by 
these activities in the expected time period or at all; 
transactions may not be completed as scheduled or at all due to legal or regulatory requirements, market conditions or contractual and 
other conditions to which such transactions are subject; 
unanticipated  adverse  consequences  could  arise  in  the  integration  or  separation  processes,  including  unanticipated  restructuring  or 
separation costs and liabilities, as well as delays or other difficulties in transitioning, coordinating, consolidating, replacing and integrating 
personnel, information and management systems, and customer products and services; and 
the diversion of management and key employees' attention may detract from our ability to increase revenues and minimize costs. 

  Failure to recruit and retain key 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 and ongoing staff reduction initiatives, 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 changes in labor laws and regulations. 

Approximately 34 percent of our total workforce, primarily employed in Norway, Brazil, the U.K. and Australia, 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.    These  negotiations  could  result  in  higher  personnel  expenses,  other  increased  costs  or  increased  operational 

AR-15 

restrictions as the outcome of such negotiations affect the market for all offshore employees not just the union members.  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. 

  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,  we  could  suffer  from  civil  and  criminal  penalties  or  other  sanctions,  which  could  have  a  material 
adverse effect on our business or our consolidated financial position and results of operations.  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 the 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, we could 
face  claims  by  agents,  shareholders,  debt  holders,  or  other  interest  holders  or  constituents  of  our  company.    Further,  disclosure  of  the 
subject matter of any investigation could adversely affect our reputation and our ability to obtain new business with potential customers or 
retain existing business with our current customers, to attract and retain employees and to access the capital markets.  Our customers in 
relevant jurisdictions could seek to impose penalties or take other actions adverse to our interests, and we may be required to dedicate 
significant time and resources to investigate and resolve allegations of misconduct, regardless of the merit of such allegations. 

  Regulation of greenhouse gases and climate change could have a negative impact on our business. 

Scientific  studies have suggested that emissions of  certain  gases,  including greenhouse gases, 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 fossil fuels, is attracting increasing attention worldwide.  For example, 
in December 2015, 195 nations  adopted the Paris Agreement, which went  into effect in November 2016.  The Paris Agreement aims to 
limit increases in global temperatures to well below two degrees Celsius.  While the greenhouse gas emission reductions called for by the 
Paris Agreement are not binding, we expect continued and increased attention to climate change.  This attention has led, and we expect it 
to continue to lead, to additional regulations designed to reduce greenhouse gas emissions domestically and internationally.  Because our 
business depends on the level of activity in the offshore oil and gas industry, existing or future laws, regulations, treaties or international 
agreements related to greenhouse gases and climate change, 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  could  result  in 
increased compliance costs or additional operating restrictions, which may have an adverse effect on our business. 

  We  are  subject  to  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.    We  have  subsidiaries  that  have  issued  debt  under  indentures  that  are  subject  to 
covenant  compliance,  some  of  which  have  been  accused  of  breaching  certain  requirements  of  such  covenants  (see  “Part II.  Item 8. 
Financial  Statements  and  Supplementary  Data—Notes 
to  Consolidated  Financial  Statements—Note 13—Commitments  and 
Contingencies—Global Marine litigation”).  Certain of our subsidiaries are named as defendants in numerous lawsuits alleging personal 
injury 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 the cases involving those subsidiaries 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 litigation matters is not resolved in our favor and is not covered by insurance, which could 
have an adverse effect on our financial position, results of operations or cash flows. 

  Our information technology systems are subject to cybersecurity risks and threats. 

We depend on 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 

AR-16 

unauthorized  access  of  information  technology  systems.    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.  Threats to our systems and 
our customers’ and vendors’ systems may derive from human error, fraud or malice 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  of  intellectual  property,  proprietary  information  or  customer  and  vendor  data;  disruption  of  our 
customers’ and vendors’ operations; loss or damage to our customer and vendor data delivery systems; and increased costs to prevent, 
respond to or mitigate cybersecurity events.  If such a cyber-incident were to occur, it could have a material adverse effect on our business 
or on our consolidated financial position, results of operations or cash flows. 

In  addition,  new  laws  and  regulations  governing  data  privacy  and  the  unauthorized  disclosure  of  confidential  information, 
including the European Union General Data Protection Regulation and recent California legislation, pose increasingly complex compliance 
challenges and potentially elevate our costs.  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 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,  which  may  have  a 

material adverse effect on our results of operations. 

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 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. 

  Public health threats could have a material adverse effect on our business and results of operations. 

Public health threats, such as Severe Acute Respiratory Syndrome, severe influenza and other highly communicable viruses or 
diseases,  outbreaks  of  which  have  already  occurred  in  various  parts  of  the  world  in  which  we  operate,  could  adversely  impact  our 
operations, the operations of our customers and the global economy, including the worldwide demand for oil and natural gas and the level 
of demand for our services.  The quarantine of personnel or inability to access our offices or rigs could adversely affect our operations.  
Travel restrictions or operational problems in any part of the world in which we operate, or any reduction in the demand for drilling services 
caused by public health threats in the future, may materially impact our operations and have an adverse effect on our results of operations. 

  We may not realize the anticipated benefits of the acquisition of Songa or Ocean Rig. 

We  believe  these  acquisitions  will  provide  benefits  to  the  combined  company  as  described  in  our  other  filings  with  the  SEC.  
However, there is a risk that some or all of the expected benefits of either or both acquisitions may fail to materialize, or may not occur 
within the time periods anticipated.  The realization of such benefits may be affected by a number of factors, many of which are beyond our 
control, including but not limited to the strength or weakness of the economy and competitive factors in the areas where we do business, 
the effects of competition in the markets in which we operate, and the impact of changes in the laws and regulations regulating the offshore 
drilling  industry  or  affecting  domestic  or  foreign  operations.    The  challenge  of  coordinating  previously  separate  businesses  makes 
evaluating  the  business  and  future  financial  prospects  of  the  combined  company  following  the  acquisition  difficult.    The  success  of  the 
acquisitions, including anticipated benefits and cost savings, will depend, in part, on our ability to successfully integrate the operations of 
each  of  these  companies  in  a  manner  that  results  in  various  benefits,  including,  among  other  things,  an  expanded  market  reach  and 
operating efficiencies, and that does not materially disrupt existing relationships nor result in decreased revenues or dividends.  Failure to 
realize the anticipated benefits of the acquisitions may impact the financial performance of the combined company. 

  We  have  incurred  significant  transaction  and  acquisition-related  costs  and  may  incur  significant  integration  costs  in 

connection with the acquisitions. 

We have incurred substantial costs in connection with the negotiation and completion of acquisitions of Songa and Ocean Rig.  
We have incurred significant legal, advisory and financial services fees in connection with the process of negotiating and evaluating the 
terms of each acquisition.  Additional significant unanticipated costs may be incurred as we continue to combine and integrate the acquired 
businesses.    We  also  have  incurred  and  will  continue  to  incur  transaction  fees  and  costs  related  to  formulating  and  implementing 
integration  plans,  including  facilities  and  systems  consolidation  costs  and  employment-related  costs.    We  continue  to  assess  the 
magnitude  of  these  costs,  and  additional  unanticipated  costs  may  be  incurred  as  we  continue  to  integrate  the  companies’  businesses.  
Although we expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the 
businesses, which should allow us to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at 

AR-17 

all (see the risk factor titled “We may not realize the anticipated benefits of the acquisition of Songa or Ocean Rig” above).  These costs 
described above, as well as other unanticipated costs and expenses, could have an adverse effect on our consolidated financial position, 
operating results and cash flows. 

Other risks 

  We have significant carrying amounts of long-lived assets that are subject to impairment testing. 

At December 31, 2018, the carrying amount of our property and equipment was $20.4 billion, representing 80 percent of our total 
assets.    In  accordance  with  our  accounting  policies,  we  review  our  property  and  equipment  for  impairment  when  events  or  changes  in 
circumstances indicate that carrying amounts of our assets held and used may not be recoverable.  We also review the carrying amounts 
of assets at the time that we classify such assets as held for sale.  In the year ended December 31, 2018, we recognized an aggregate 
loss  of  $999 million  associated  with  the  impairment  of  certain  assets  that  we  determined  were  impaired  at  the  time  the  assets  were 
classified as held for sale.  In the year ended December 31, 2017, we recognized an aggregate loss of $1.4 billion associated  with the 
impairment of certain assets that we determined were impaired at the time the assets were classified as held for sale and an aggregate 
loss  of  $94 million  associated  with  the  impairment  of  our  midwater  floater  asset  group.    Future  expectations  of  lower  dayrates  or  rig 
utilization rates or a significant change to the composition of one or more of our asset groups could result in the recognition of additional 
losses on impairment of our long-lived asset groups if future cash flow expectations, based on information available to management at the 
time of measurement, indicate that the carrying amount of our asset groups may be impaired. 

  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 worldwide earnings, which could result in a 
significant adverse effect on our earnings and cash flows from operations. 

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.    A 
material change in the tax laws, treaties or regulations, or their interpretation or application, of any country in which we have significant 
operations,  or  in  which  we  are  incorporated  or  resident,  could  result  in  a  higher  effective  tax  rate  on  our  worldwide  earnings  and  such 
change could be significant to our financial results.  Switzerland, for example, has been carefully considering various tax reform proposals 
in response to certain guidance from and demands by the European Union (“EU”) and the Organization for Economic Co-operation and 
Development (the “OECD”).  Some of these tax reform measures may be adopted into law and effective as early as 2019.  Similarly, the 
OECD 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 have adopted various 
measures into their own tax laws.  In addition, the EU issued its Anti-Tax Avoidance Directive in 2016 that required its member states to 
adopt specific tax reform measures by 2019.  Other tax jurisdictions in which we operate may consider implementing similar legislation.  
Any material change to tax laws or policies, their interpretation or the adoption of new interpretations of existing laws and rulings in any of 
the jurisdictions in which we operate could result in a higher effective tax rate on our worldwide earnings and such change could have a 
significant adverse effect on our consolidated 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  worldwide 
earnings, which could result in a significant negative impact on our earnings and cash flows from operations. 

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, particularly  in the U.S., India, Brazil or Nigeria, 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  cannot  be  certain  that  the  U.S.  Internal  Revenue  Service  (“IRS”)  will  not  successfully  contend  that  we  or  any  of  our  key 
subsidiaries were or are engaged in a trade or business in the U.S. or that we or any of our key subsidiaries maintained or maintain a 
permanent establishment in the U.S.  The determination of the aforementioned, among other things, involves considerable uncertainty.  If 
we  or  any  of  our  key  subsidiaries  were  determined  to  have  been  engaged  in  a  trade  or  business  in  the  U.S.  through  a  permanent 
establishment,  then  we  could  be  subject  to  U.S.  corporate  income  and  additional  branch  profits  taxes  on  the  portion  of  our  earnings 
effectively connected to such U.S. business 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, and our earnings and cash flows from operations for that period 
could be adversely affected. 

AR-18 

  U.S. tax authorities could treat us as a passive foreign investment company, which would have adverse U.S. federal income 

tax consequences to U.S. holders. 

A foreign corporation will be treated as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes if 
either (1) at least 75 percent of its gross income for any taxable year consists of certain types of passive income or (2) at least 50 percent 
of the average value of the corporation's assets produce or are held for the production of those types of passive income.  For purposes of 
these tests, passive income includes dividends, interest and gains from the sale or exchange of investment property and certain rents and 
royalties, but does not include income derived from performing services. 

We believe that we have not been and will not be a PFIC with respect to any taxable year.  Our income from offshore contract 
drilling services should be treated as services income for purposes of determining whether we are a PFIC.  Accordingly, we believe that 
our income from our offshore contract drilling services should not constitute passive income, and the assets that we own and operate in 
connection  with  the  production  of  that  income  should  not  constitute  passive  assets.    There  is  significant  legal  authority  supporting  this 
position, including statutory provisions, legislative history, case law and IRS pronouncements concerning the characterization, for other tax 
purposes, of income derived from services where a substantial component of such income is attributable to the value of the property or 
equipment used in connection with providing such services.  However, a prior case and an IRS pronouncement that relies on the case 
characterize income from time chartering of vessels as rental income rather than services income for other tax purposes.  The IRS has 
subsequently formally announced that it does not agree with the decision in that case.  Moreover, we believe that the terms of the time 
charters in the prior case differ in material respects from the terms of our drilling contracts with customers.  No assurance can be given that 
the IRS or a court will accept our position, and there is a risk that the IRS or a court could determine that we are a PFIC. 

If we were treated as a PFIC for any taxable year, our U.S. shareholders would face adverse U.S. tax consequences.  Under the 
PFIC  rules,  unless  a  shareholder  makes  certain  elections  available  under  the  Internal  Revenue  Code  of  1986,  as  amended,  and  such 
elections could themselves have adverse consequences for the shareholder, the shareholder could be required to pay U.S. federal income 
tax  at  the  highest  applicable  income  tax  rates  on  ordinary  income  upon  the  receipt  of  excess  distributions,  as  defined  for  U.S.  tax 
purposes, and upon any gain from the disposition of our shares, plus interest on such amounts, as if such excess distribution or gain had 
been  recognized  ratably  over  the  shareholder’s  holding  period  of  our  shares.    Additionally,  under  applicable  statutory  provisions,  the 
preferential  tax  rate  on  qualified  dividend  income,  which  applies  to  dividends  paid  to  non-corporate  shareholders,  does  not  apply  to 
dividends  paid  by  a  foreign  corporation  if  the  foreign  corporation  is  a  PFIC  for  the  taxable  year  in  which  the  dividend  is  paid  or  the 
preceding taxable year. 

  As a Swiss corporation, our flexibility may be limited with respect to certain aspects of capital management, and we may be 

unable to make distributions or repurchase shares without subjecting our shareholders to Swiss withholding tax. 

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.  The authorized share capital is limited to a maximum of 
50 percent of a company’s registered share capital.  The authorized share capital approved by our shareholders at the May 2018 annual 
general meeting will expire on May 18, 2020.  Accordingly, shareholders at our annual general meeting in May 2019 are not expected to be 
requested  to  approve  an  authorized  share  capital.    Our  current  authorized  share  capital  is  limited  to  approximately  five percent  of  our 
registered  share  capital.    Additionally,  subject  to  certain  exceptions,  Swiss  law  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 over which a board of directors would have authority in some other jurisdictions.  For example, dividends must be approved by 
shareholders.  These Swiss law requirements relating to our capital management may limit our flexibility, and situations may arise where 
greater flexibility would have provided substantial benefits to our shareholders. 

Distributions to shareholders in the form of a par value reduction and dividend distributions out of qualifying additional paid-in 
capital are not currently subject to the 35 percent Swiss federal withholding tax.  However, the Swiss withholding tax rules could also 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 3.5 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 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. 

AR-19 

  Swiss corporate governance may affect our business. 

The Swiss Federal Council Ordinance Against  Excessive Compensation at Public Companies  (the “Ordinance”), among other 
things, (a) requires a binding shareholder “say on pay” vote with respect to the compensation of members of our executive management 
and board of directors, (b) generally prohibits the making of severance, advance, transaction premiums and similar payments to members 
of our executive management and board of directors, and (c) requires the declassification of our board of directors and the amendment of 
our articles of association to specify various compensation-related matters.  At our annual general meetings, our shareholders are required 
to  approve  the  maximum  aggregate  compensation  of  (1) our  board  of  directors  for  the  period  through  the  successive  annual  general 
meeting  and  (2) our  executive  management  team  for  the  following  year.    The  Ordinance  further  provides  for  criminal  penalties  against 
directors  and  members  of  executive  management  in  case  of  noncompliance  with  certain  of  its  requirements.    The  Ordinance  may 
negatively affect our ability to attract and retain executive management and members of our board of directors. 

  As a Swiss corporation, we are subject to Swiss legal provisions that may limit our flexibility to swiftly implement certain 

initiatives or strategies. 

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.  The 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 statutory capital reserves, the board of directors must convene a general meeting of shareholders and propose 
measures  to  remedy  such  a  capital  loss.    The  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.  These Swiss law requirements could limit our flexibility to swiftly implement certain initiatives or strategies. 

  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 18, 2020, to issue a specified number of 
shares, which under our current authorized share capital is approximately five percent of the share capital registered in the commercial 
register, 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 
24 percent of the share capital registered in the commercial register as of February 12, 2019, 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. 

  The results of the U.K.’s referendum on withdrawal from the European Union may have a negative effect on our business. 

In  June 2016,  a  majority  of  voters  in  the  U.K.  elected  to  withdraw  from  the  European  Union  in  a  national  referendum,  and  in 
March 2017, the government of the U.K. formally initiated the process.  The referendum was advisory, and the terms of any withdrawal are 
subject  to  a  negotiation  period  that  could  last  at  least  two years  after  the  March 2017  initiation.    Though  the  U.K.  withdrawal  from  the 
European  Union  is  scheduled  to  occur  in  March 2019,  there  is  currently  no  agreement  in  place  regarding  the  withdrawal,  creating 
significant  uncertainty  about  the  future  relationship  between  the  U.K.  and  the  European  Union,  including  with  respect  to  the  laws  and 
regulations that will apply as the U.K. determines which European Union-derived laws to replace or replicate in the event of a withdrawal.  
The referendum has also given rise to calls for the governments of other European Union member states to consider withdrawal.  These 
developments, or the perception that any of them could occur, have had and may continue to have an adverse effect on global economic 

AR-20 

conditions and the stability of global financial markets, and may significantly reduce global market liquidity and restrict the ability of key 
market participants to operate in certain financial markets.  Any of these factors could depress economic activity and restrict our access to 
capital, which could have a material adverse effect on our business and on our consolidated financial position, results of operations or cash 
flows.

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 (“NYSE”) under the ticker symbol “RIG.”  On February 11, 2019, we had 

610,061,503 shares outstanding and 5,718 holders of record of our shares. 

Shareholder Matters 

Share issuance 

In connection with the acquisition of Songa Offshore SE, a European public company limited by shares, or societas Europaea, 
existing under the laws of Cyprus (“Songa”), shareholders at our extraordinary general meeting, held January 16, 2018, were requested to 
consider the following: (1) the issuance of up to 68.6 million Transocean Ltd. shares, (2) an amendment of our articles of association to 
create  additional  authorized  share  capital,  (3) election  of  one new  director  to  our  board  of  directors  and  (4) issuance  of  consideration 
shares of our authorized share capital and our shares issuable upon exchange of the 0.50% exchangeable senior bonds due January 2023 
(the “Exchangeable Bonds”).  On January 18, 2018, we announced that shareholders at our extraordinary general meeting approved all 
proposals related to the Songa acquisition.  On January 30, 2018, we completed the acquisition of an approximate 97.7 percent ownership 
interest in Songa.  On March 28, 2018, we acquired the remaining shares not owned by us through a compulsory acquisition under Cyprus 
law  and  as  a  result,  Songa  became  our  wholly  owned  subsidiary.    To  complete  these  transactions,  we  issued  68.0 million  shares  and 
$863 million aggregate principal amount of the Exchangeable Bonds and made an aggregate cash payment of $8 million. 

In  connection  with  the  acquisition  of  Ocean Rig  UDW Inc.,  a  Cayman  Islands  exempted  company  with  limited  liability 
(“Ocean Rig”),  shareholders  at  our  extraordinary  general  meeting,  held  November 29,  2018,  were  requested  to  consider  the  following: 
(1) an  amendment  of  our  articles  of  association  to  create  additional  authorized  share  capital,  (2) the  issuance  of  up  to  147.7 million 
Transocean Ltd.  (together  with  its  subsidiaries  and  predecessors,  unless  the  context  requires  otherwise,  “Transocean,”  the  “Company,” 
“we,” “us” or “our”) shares and (3) the deletion of the previously  approved special purpose authorized share capital.  On November 29, 
2018, we announced that shareholders at our extraordinary general meeting approved all proposals related to the Ocean Rig acquisition.  
On December 5, 2018, we completed the acquisition of Ocean Rig in a merger transaction and as a result, Ocean Rig became our wholly 
owned subsidiary.  To complete the acquisition, we issued 147.7 million Transocean Ltd. shares and made an aggregate cash payment of 
$1.2 billion. 

See  “Part II.  Item 8.  Financial  Statements  and  Supplementary  Data—Notes  to  Consolidated  Financial  Statements  and 

4─Business Combinations.” 

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,  2018,  the  aggregate  amount  of  par  value  of  our 
outstanding shares was CHF 61 million, equivalent to approximately $62 million, and the aggregate amount of qualifying additional paid-in 

AR-23 

capital  of  our  outstanding  shares  was  CHF 13.4 billion,  equivalent  to  approximately  $13.7 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 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 United States (“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. 

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 

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.  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. 

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  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 11, 2019, Transocean Inc., our wholly owned subsidiary, held as treasury 
shares less than one 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 current number of shares held as 
treasury shares, approximately nine percent of our issued shares could be repurchased for purposes of retention as additional treasury 

AR-24 

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.

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 3.5 billion.  At December 31, 2018, the authorization remaining 
under the share repurchase program was for the repurchase of our outstanding shares for an aggregate cost of up to CHF 3.2 billion, equivalent to 
$3.3 billion.  The share repurchase program could be suspended or discontinued by our board of directors or company management, as applicable,

In December 2018, we acquired Ocean Rig UDW Inc. (“Ocean Rig”) in a merger transaction, and as a result, Ocean Rig became our wholly owned 
subsidiary.  To complete the acquisition, we issued 147.7 million shares and made an aggregate cash payment of $1.2 billion. 
In  January 2018,  we  acquired  approximately  97.7 percent  ownership  interest  in  Songa  Offshore SE  (“Songa”).    In  March 2018,  we  acquired  the 
remaining shares not owned by us through a compulsory acquisition under Cyprus law and as a result Songa became our wholly owned subsidiary.  
To complete these transactions, we issued 68.0 million shares and $863 million aggregate principal amount of the Exchangeable Bonds and made 
an aggregate cash payment of $8 million.  
In December 2016, Transocean Partners LLC (“Transocean Partners”) completed a merger with one of our subsidiaries as contemplated under the 
merger agreement.  Following the completion of the merger, Transocean Partners became our wholly owned subsidiary.  Each Transocean Partners 
common  unit  that  was  issued  and  outstanding  immediately  prior  to  the  closing,  other  than  units  held  by  Transocean  and  its  subsidiaries,  was 
converted into the right to receive 1.20 of our shares.  To complete the merger, we issued 23.8 million shares from conditional capital. 
In August 2014, we completed an initial public offering to sell a noncontrolling interest in Transocean Partners, which was formed on February 6, 
2014, by Transocean Partners Holdings Limited, a Cayman Islands company and our wholly owned subsidiary.

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

The  following  information  should  be  read  in  conjunction  with  the  information  contained  in  “Part I.  Item 1.  Business,”  “Part I. 
Item 1A.  Risk  Factors”  and  the  audited  consolidated  financial  statements  and  the  notes  thereto  included  under  “Item 8.  Financial 
Statements and Supplementary Data” elsewhere in this annual report. 

Business 

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 11,  2019,  we  owned  or  had  partial  ownership  interests  in  and  operated  a  fleet  of  49 mobile  offshore  drilling  units,  including 
31 ultra-deepwater  floaters,  14 harsh  environment  floaters  and  four midwater  floaters.    As  of  February 11,  2019,  we  were  constructing 
(i) four additional  ultra-deepwater  drillships  and  (ii) one additional  harsh  environment  semisubmersible,  in  which  we  hold  a  partial 
ownership interest. 

We provide contract drilling services in a single, global operating segment, which involves contracting our mobile offshore drilling 
fleet, related equipment and work crews primarily on a dayrate basis to drill oil and gas wells.   We specialize in technically demanding 
regions of the 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. 

Our  contract  drilling  services  operations  are  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.  Our fleet operates in a single, global market for the provision of contract drilling 
services.  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 

Business  combinations—On  January 30,  2018,  we  acquired  an  approximate  97.7 percent  ownership  interest  in  Songa 
Offshore SE (“Songa”).  On March 28, 2018, we acquired the remaining shares not owned by us through a compulsory acquisition under 
Cyprus law, and as a result Songa became our wholly owned subsidiary.  To complete these transactions, we issued 68.0 million shares 
and $863 million aggregate principal amount of 0.50% exchangeable senior bonds due January 30, 2023 (the “Exchangeable Bonds”).  As 
a  result  of  the  acquisition,  we  acquired  seven mobile  offshore  drilling  units,  including  five harsh  environment  floaters  and  two midwater 
floaters.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.” 

On  December 5,  2018,  we  acquired  Ocean Rig  UDW Inc.  (“Ocean Rig”)  in  a  merger  transaction,  and  as  a  result,  Ocean Rig 
became our wholly owned subsidiary.  To complete the acquisition, we issued 147.7 million shares and made an aggregate cash payment 
of $1.2 billion.  As a result of the acquisition, we acquired (i) 11 mobile offshore drilling units, including nine ultra-deepwater floaters and 
two harsh environment floaters, and (ii) the contracts relating to the construction of two ultra-deepwater drillships.  In February 2019, we 
committed to plans to sell one ultra-deepwater floater and one harsh environment floater acquired in the Ocean Rig acquisition.  See “—
Liquidity and Capital Resources—Sources and uses of liquidity.” 

Impairments—In the year ended December 31, 2018, we recognized an aggregate loss of $999 million, which had no tax effect, 
associated  with  the  impairment  of  four ultra-deepwater  floaters,  two deepwater  floaters  and  two midwater  floaters,  along  with  related 
assets, which we determined were impaired at the time we classified the assets as held for sale, and we recognized a loss of $462 million, 
which had no tax effect, associated with the impairment of our goodwill.  See “—Operating Results.” 

Secured  Credit  Facility—In  June 2018,  we  entered  into  a  bank  credit  agreement,  which  established  a  $1.0 billion  secured 
revolving credit facility (the “Secured Credit Facility”), and we terminated the former bank credit agreement.  See “—Liquidity and Capital 
Resources—Sources and uses of liquidity.” 

Debt  issuances—In  July 2018,  we  issued  $750 million  aggregate  principal  amount  of  5.875% senior  secured  notes  due 
January 2024  (the  “5.875% Senior  Secured  Notes”),  and  $600 million  aggregate  principal  amount  of  6.125% senior  secured  notes  due 
August 2025 (the “6.125% Senior Secured Notes”), together the “2018 Senior Secured Notes”, and we received approximately $733 million 
and $586 million, respectively, of aggregate cash proceeds, net of discount and issue costs.  On October 25, 2018, we issued $750 million 
aggregate principal amount of 7.25% senior unsecured notes due November 2025 (the “7.25% Senior Notes”), and we received aggregate 
cash  proceeds  of  $735 million,  net  of  issue  costs.    On  February 1,  2019,  we  issued  $550 million  aggregate  principal  amount  of 
6.875% senior  secured  notes  due  February 2027  (the  “6.875% Senior  Secured  Notes”),  and  we  received  aggregate  cash  proceeds  of 
$538 million, net of discount and issue costs.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.” 

Debt  retirement—In  the  year ended  December 31,  2018,  we  made  an  aggregate  cash  payment  of  $1.6 billion  to  repay  debt 
assumed  in  the  Songa  acquisition.    In  the  year ended  December 31,  2018,  we  repurchased  in  the  open  market  $95 million  aggregate 

AR-27 

principal amount of our debt securities for an aggregate cash payment of $95 million.  See “—Liquidity and Capital Resources—Sources 
and uses of liquidity.” 

Debt tender offers—On February 5, 2019, we completed tender offers (the “2019 Tender Offers”) to purchase for cash up to 
$700 million aggregate purchase price of certain outstanding senior notes (the “2019 Tendered Notes”).  In January and February 2019, as 
a  result  of  the  2019 Tender  Offers,  we  made  an  aggregate  cash  payment  of  $521 million  to  settle  the  validly  tendered  2019 Tendered 
Notes.  In the three months ending March 31, 2019, we expect to recognize an aggregate net loss of approximately $18 million associated 
with the retirement of debt.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.” 

Investment  in  unconsolidated  affiliates—In  May 2018  and  January 2019,  we  made  an  aggregate  cash  investment  of 
$91 million and $59 million, respectively, representing a 33.0 percent ownership interest in Orion Holdings (Cayman) Limited, a Cayman 
Islands  company  formed  to  construct  and  own  the  newbuild  harsh  environment  semisubmersible  Transocean Norge.    We  expect  to 
operate the rig, through one of our wholly owned subsidiaries, under a six-well drilling contract that is expected to commence in July 2019.  
See “—Liquidity and Capital Resources—Sources and uses of liquidity.” 

Fleet  expansion—In  February 2018,  we  completed  the  construction  of  and  placed  into  service  the  ultra-deepwater  floater 

Deepwater Poseidon.  See “—Liquidity and Capital Resources—Drilling fleet.” 

Dispositions—During the year ended December 31, 2018, we completed the sale of six ultra-deepwater floaters, one deepwater 
floater and one midwater floater, along with related assets, for which we received aggregate net cash proceeds of $36 million.  See “—
Operating Results” and “—Liquidity and Capital Resources—Drilling fleet.” 

Outlook 

Drilling market—Our long-term view of the part of the offshore drilling market in which we participate is positive, especially for 
the highest specification floaters.  Brent oil prices, although somewhat volatile, remained above $60 per barrel for most of 2018, improving 
our customers’ economics for drilling oil and gas wells and providing positive support for our customers’ budget cycles for 2019.  Structural 
efficiency gains across the industry, which resulted in improved  economics for offshore development, and some favorable trends in the 
hydrocarbon  supply-demand  balance  whereby  oil  supply  has  declined  relative  to  demand,  resulted  in  an  increase  in  our  customers’ 
investment decisions in 2018.  We expect this trend of additional investment by our customers to continue in 2019. 

Over the past year, opportunities have increased for our drilling services.  In markets requiring harsh environment floating drilling 
rigs,  such  as  the  Norwegian  North  Sea  and  eastern  Canada,  the  limited  supply  of  these  specialized  rigs  has  improved  fleet  utilization, 
which has resulted in increased dayrates on high-specification rigs being tendered for new work.  Outside of harsh environment markets, 
the excess supply of ultra-deepwater floaters relative to demand  has delayed improvement of dayrates despite the increase in contract 
activity.  However, as the hydrocarbon supply-demand balance improves, we expect that stability and sustained improvement of oil prices 
will ultimately result in greater demand for ultra-deepwater drilling rigs and improvement of dayrates as utilization tightens. 

As of February 11, 2019, our contract backlog was $12.2 billion compared to $11.5 billion as of October 22, 2018.  We believe 
the risks of drilling project delays, contract renegotiations and contract terminations and cancellations have diminished as oil prices have 
improved and our customers’ cash positions have improved. 

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 11, 2019, the uncommitted fleet rates for each of the five years in the period ending December 31, 2023 were as 

follows: 

Uncommitted fleet rate 
Ultra-deepwater floaters
Harsh environment floaters 
Midwater floaters

Contract backlog—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.  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 commencement of operations.

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 and represents the basis for the maximum revenues in our revenue efficiency 
measurement.  To determine maximum revenues for purposes of calculating revenue efficiency, however, we include the revenues earned 
for mobilization, demobilization and contract preparation, other incentive provisions or cost escalation provisions which are excluded from 
the amounts presented for contract backlog. 

The contract backlog for our fleet was as follows:

Our contract backlog includes only firm commitments, which are represented by signed drilling contracts or, in some cases, by 
other definitive agreements awaiting contract execution.  Our contract backlog includes amounts associated with our newbuild units that 
are  currently  under  construction.    The  contractual  operating  dayrate  may  be  higher  than  the  actual  dayrate  we ultimately  receive  or  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 dayrate may be reduced to zero if, for example, 
repairs extend beyond a stated period of time. 

In  connection  with  our  Ocean Rig  acquisition,  we  acquired  contract  backlog  of  approximately  $650 million,  included  in  the 
contract  backlog  for  our  ultra-deepwater  and  harsh  environment  floaters  presented  above,  measured  as  of  the  acquisition  date, 
December 5, 2018.  In connection with our Songa acquisition, we acquired contract backlog of $3.7 billion, included in the contract backlog 
for our harsh environment floaters presented above, measured as of the acquisition date, January 30, 2018. 

In December 2018, we and a subsidiary of Chevron Corporation (together with its affiliates, “Chevron”) entered into a rig design 
and  construction  contract  and  a  five-year  drilling  contract  for  one of  our  ultra-deepwater  drillships  under  construction  at  the  Jurong 
Shipyard Pte Ltd. in Singapore.  The drilling contract added $830 million of estimated contract backlog.  The drilling contract is subject to 
design, construction and delivery requirements set forth in the construction contract.  In the event of termination for convenience by the 
customer, we will be compensated for our incremental 20,000 pounds per square inch (“psi”) subsea investment in the rig, and termination 
for convenience after April 2020 will result in a substantial termination fee. 

At February 11, 2019, the contract backlog and average contractual dayrates for our fleet were as follows:

Ultra-deepwater floaters 
Harsh environment floaters 
Midwater floaters

The actual amounts of revenues earned and the actual periods during 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 revenue to be recognized include customer liquidity issues and contract terminations, which are available to 
our customers under certain circumstances.

Our average daily revenue fluctuates relative to market conditions and our revenue efficiency.  The average daily revenue may 
also be affected by revenues for lump sum bonuses or demobilization fees received from our customers and is reduced by the amortization 
of  the  contract  intangible  assets  acquired  in  the  Songa  acquisition  and,  to  a  lesser  extent,  the  Ocean  Rig  acquisition.    Our  total  fleet 
average  daily  revenue  is  also  affected  by  the  mix  of  rig  classes  being  operated,  as  deepwater  floaters,  midwater  floaters  and 
high-specification jackups are typically contracted at lower dayrates compared to ultra-deepwater floaters and harsh environment floaters.  
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, unless we continue to operate rigs subsequent to sale, as we did with three of 
the high-specification jackups sold in May 2017, in which case we remove the rigs at the time of completion or novation of the contract. 

Revenue  efficiency—Revenue  efficiency  is  defined  as  actual  contract  drilling  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, excluding revenues from 
contract terminations and reimbursements, the drilling unit could earn for the measurement period, excluding amounts related to incentive 
provisions.  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.  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—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, classification as held for sale or classification as discontinued operations.  
Accordingly, our rig utilization can increase when idle or stacked units are removed from our drilling fleet.

Contract drilling revenues—Contract drilling revenues increased for the year ended December 31, 2018 compared to the year 
ended  December 31,  2017  primarily  due  to  the  following:  (a) approximately  $515 million  resulting  from  operations  acquired  in  the 
acquisitions  of  Songa  and  Ocean Rig,    (b) approximately  $335 million  resulting  from  our  two newbuild  ultra-deepwater  drillships  that 
commenced  operations  in  the  two-year  period  ended  December 31,  2018,  (c) approximately  $125 million  resulting  from  contract  early 
terminations and cancellations, (d) approximately $110 million resulting from the reactivation of two rigs and (e) approximately $90 million 
of  reimbursement  revenues.    These  increases  were  partially  offset  by  the  following  decreases:  (a) approximately  $375 million  resulting 
from lower dayrates, (b) approximately $345 million resulting from a greater number of rigs idle or stacked, (c) approximately $135 million 
resulting from rigs sold or classified as held for sale and (d) approximately $40 million resulting from lower revenue efficiency. 

Other  revenues  for  the  year  ended  December 31,  2017,  included  revenues  of  $201 million  resulting  from  contract  early 
terminations and cancellations and $41 million of reimbursement revenues.  For the year ended December 31, 2018, these activities are 
presented in contract drilling revenues as part of our single performance obligation. 

Costs and expenses—Operating and maintenance expense increased for the year ended December 31, 2018 compared to the 
year  ended  December 31,  2017,  primarily  due  to  the  following:  (a) approximately  $290 million  resulting  from  operations  acquired  in  the 
acquisitions  of  Songa  and  Ocean Rig,  (b) approximately  $80 million  resulting  from  our  two newbuild  ultra-deepwater  drillships  that 
commenced  operations  in  the  two-year  period  ended  December 31,  2018,  (c) approximately  $65 million  resulting  from  increased  costs 
primarily associated with changes to our country of operations and maintenance programs, (d) approximately $55 million resulting from the 
reactivation  of  three rigs  and (e) approximately  $45 million  resulting  from  increased  reimbursable  costs.    These  increases  were  partially 
offset by the following decreases: (a) approximately $80 million resulting from a greater number of rigs sold or classified as held for sale 
and (b) approximately $50 million resulting from a greater number of rigs idle or stacked. 

Depreciation  expense  decreased  for  the  year  ended  December 31,  2018  compared  to  the  year  ended  December 31,  2017 
primarily  due  to  the  following:  (a) approximately  $120 million  resulting  from  rigs  sold  or  classified  as  held  for  sale,  (b) approximately 
$20 million resulting from the retirement or full depreciation of certain assets and (c) approximately $5 million resulting from the impairment 
of  our  midwater  floater  asset  group  in  the  year ended  to  December 31,  2017.    These  decreases  were  partially  offset  by  the  following 
increases: (a) approximately $82 million resulting from the rigs acquired in the acquisitions of Songa and Ocean Rig and (b) approximately 
$49 million resulting from our two newbuild ultra-deepwater drillships placed into service in the two-year period ended December 31, 2018.

General  and  administrative  expense  increased  for  the  year  ended  December 31,  2018  compared  to  the  year  ended 
December 31, 2017, primarily due to the following: (a) approximately $18 million of increased acquisition costs related to the acquisitions of 
Songa  and  Ocean Rig,  (b) approximately  $7 million  of  increased  professional  fees  related  to  developing  technology  for  improving  fleet 
performance and reducing costs and (c) approximately $4 million of increased personnel costs, primarily resulting from costs associated 
with the early retirement of certain personnel. 

Loss  on  impairment  or  disposal  of  assets—In  the  year  ended  December 31,  2018,  we  recognized  losses  related  to  the 
following: (a) $999 million associated with the impairment of certain assets classified as held for sale and (b) $462 million associated with 
the impairment of goodwill.  In the year ended December 31, 2017, we recognized losses related to the following: (a) a loss of $1.4 billion 
associated with the impairment of certain assets classified as held for sale and (b) a loss of $94 million associated with the impairment of 
our midwater floater asset group. 

In  the  year  ended  December 31,  2018,  we  recognized  an  aggregate  gain  of  $7 million  associated  with  the  sale  of 
six ultra-deepwater floaters, one deepwater floater and one midwater floater, along with related assets.  In the year ended December 31, 
2018,  we  recognized  an  aggregate  loss  of  $7 million  associated  with  the  disposal  of  assets  unrelated  to  rig  sales.    In  the  year  ended 
December 31, 2017, loss on disposal of assets was primarily due to the sale of 10 high-specification jackups and novation of the contracts 
relating to the construction of five high-specification jackups, together with related assets. 

Other income and expense—Interest expense, net of amounts capitalized,  increased in the year ended December 31, 2018 
compared  to  the  year  ended  December 31,  2017,  primarily  due  to  the  following:  (a) approximately  $98 million  reduced  interest  costs 
capitalized  for  our  newbuild  ultra-deepwater  drillships  placed  into  service  in  the  two-year  period  ended  December 31,  2018, 
(b) approximately  $78 million  resulting  from  debt  issued  in  the  two-year  period  ended  December 31,  2018  and  (c) approximately 
$32 million  resulting  from  the  debt  and  related  undesignated  derivative  instruments  issued  or  assumed  in  connection  with  the  Songa 
acquisition.  These increases were partially offset by a decrease of approximately $83 million resulting from the retirement of debt. 

Loss on retirement of debt in the year ended December 31, 2017 resulted primarily from the following: (a) an aggregate loss of 
$48 million  resulting  from  the  retirement  of  notes  validly  tendered  in  the  cash  tender  offers  completed  July 11,  2017  (the  “2017 Tender 
Offers”) and (b) an aggregate loss of $7 million resulting from debt redemptions and repurchases. 

Other income, net, increased in the year ended December 31, 2018 compared to the year ended December 31, 2017, primarily 
due to the following: (a) an increase of $45 million associated with receipt of payments related to our dual-activity patent, (b) an increase of 
$15 million associated with the non-service component of net periodic benefit costs, (c) $10 million associated with the bargain purchase 
gain resulting from the Ocean Rig acquisition with no comparable activity in the prior year and (d) $4 million associated with undesignated 
interest  rate  swaps  acquired  in  the  Songa  acquisition  and  subsequently  terminated  in  the  year  ended  December 31,  2018  with  no 
comparable  activity  in  the  prior  year.    These  increases  were  partially  offset  by  a  decrease  of  $33 million  associated  with  currency 
exchange, $21 million of which resulted from undesignated currency derivative instruments in the current year. 

Income  tax  expense—In  the  years  ended  December 31,  2018  and  2017,  our  effective  tax  rate  was  (12.8) percent  and 
(3.1) percent, respectively, based on loss before income tax expense.  In the years ended December 31, 2018 and 2017, the effect of the 
various discrete period tax items represented a net tax expense of $143 million and a net tax benefit of $37 million, respectively.  In the 
year  ended  December 31,  2018,  such  discrete  items  were  primarily  related  to  the  United  States  (“U.S.”)  transition  tax  on  non-U.S. 
earnings.  In the year ended December 31, 2017, such discrete items were primarily related to the tax benefit of changes in unrecognized 
tax  benefits  associated  with  tax  positions  taken  in  prior  years,  valuation  allowances  on  deferred  tax  assets  and  foreign  tax  credits  not 
expected to be realized, remeasurement of the U.S. deferred tax assets for a tax rate change as a result of the enactment of the Tax Cuts 
and Jobs Act (the “2017 Tax Act”) and deductions related to resolution of certain litigation matters related to Macondo well incident.  In the 
years  ended  December 31,  2018  and  2017,  our  effective  tax  rate,  excluding  discrete  items,  was  (29.2) percent  and  95.2 percent, 
respectively, based on loss before income tax expense.  Our effective tax rate decreased in the year ended December 31, 2018 compared 
to the year ended December 31, 2017, primarily due to changes in the relative blend of income from operations in certain jurisdictions and 
a loss before income taxes and the increased tax expense as a result of the U.S. base erosion and anti-abuse tax (“BEAT”). 

The 2017 Tax Act amended existing U.S. tax laws that had an impact on our income tax provision, such as a reduction of the 
U.S.  corporate  income  tax  rate  and  the  creation  of  a  quasi-territorial  tax  system  with  a  one-time  mandatory  tax  on  certain  unremitted 
earnings and profits of the non-U.S. subsidiaries of our U.S. subsidiaries.  The 2017 Tax Act also made prospective changes, effective in 
2018, including BEAT, a global intangible low-taxed income tax, additional limitations on the deductibility of executive compensation and 
interest  and  the  repeal  of  the  domestic  manufacturing  deduction.    In  the  year  ended  December 31,  2018,  we  recognized  income  tax 
expense of $33 million related to the bareboat charter structure of our U.S. operations because we concluded it was subject to BEAT.  A 
significant portion of our BEAT liability is contractually reimbursable by our customers due to a change-in-law provision in certain drilling 
contracts.  In the year ended December 31, 2017, we recognized income tax expense of $66 million with a corresponding decrease to our 
net deferred tax assets to reflect the reduction in the U.S. corporate income tax rate from 35 percent to 21 percent. 

As of December 31, 2018, our consolidated cumulative loss recognized over the recent three-year period, primarily due to losses 
on impairment and disposal of assets, represented significant objective negative evidence for our evaluation of our deferred tax assets.  
Although such evidence has limited our ability to consider other subjective evidence, we analyze each jurisdiction separately.  We consider 
objective  evidence,  such  as  contract  backlog  activity  in  jurisdictions  in  which  we  have  profitable  contracts.    If  estimated  future  taxable 

AR-32 

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. 

Due  to  factors  related  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, 
2018, a significant portion of our income tax expense was generated in countries in which income taxes are imposed on gross revenues, 
with the most significant of these countries being India.  Conversely, the countries in which we incurred the most significant income taxes 
during this period that were based on income before income tax include Brazil, Switzerland, Norway, the United Kingdom (“U.K.”) and the 
U.S.  Our rig operating structures further complicate our tax calculations, especially in instances where we have more than one operating 
structure for the particular taxing jurisdiction and, thus, more than one method of calculating taxes depending on the operating structure 
utilized by the rig under the contract.  For example, two rigs operating in the same country could generate significantly different provisions 
for  income  taxes  if  they  are  owned  by  two different  subsidiaries  that  are  subject  to  differing  tax  laws  and  regulations  in  the  respective 
country of incorporation.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes.

Contract drilling revenues—Contract drilling revenues decreased for the year ended December 31, 2017 compared to the year 
ended  December 31,  2016  primarily  due  to  the  following:  (a) approximately  $600 million  resulting  from  a  greater  number  of  rigs  idle  or 
stacked, (b) approximately $450 million resulting from rigs sold or classified as held for sale, (c) approximately $255 million resulting from 
lower dayrates and (d) approximately $45 million resulting from decreased revenue efficiency.  These decreases were partially offset by 
the  following  increases:  (a) approximately  $325 million  resulting  from  our  four  newbuild  ultra-deepwater  drillships  that  commenced 
operations in the two-year period ended December 31, 2017 and (b) approximately $65 million resulting from the reactivation of two rigs. 

Other revenues decreased for the year ended December 31, 2017 compared to the year ended December 31, 2016, due to the 
following: (a) $196 million resulting from drilling contracts early terminated or cancelled by our customers, and (b) $18 million resulting from 
reimbursable items. 

Costs and expenses—Operating and maintenance expense decreased for the year ended December 31, 2017 compared to the 
year ended December 31, 2016, primarily due to the following: (a) approximately $250 million resulting from rigs sold or classified as held 
for sale, (b) approximately $170 million resulting from a greater number of rigs idle or stacked, (c) approximately $90 million resulting from

reduced onshore costs and (d) approximately $75 million resulting from reduced offshore costs.  These decreases were partially offset by 
the  following  increases:  (a) approximately  $75 million  resulting  from  our  four newbuild  ultra-deepwater  drillships  that  commenced 
operations  in  the  two-year  period  ended  December 31,  2017  and  (b) approximately  $30 million  resulting  from  cost  recoveries  from 
insurance associated with the Macondo well incident in the year ended December 31, 2016 with no comparable activity in the year ended 
December 31, 2017. 

Depreciation  expense  decreased  for  the  year  ended  December 31,  2017  compared  to  the  year  ended  December 31,  2016 
primarily  due  to  the  following:  (a) approximately  $82 million  resulting  from  rigs  sold  or  classified  as  held  for  sale  and  (b) approximately 
$22 million  primarily  resulting  from  the  retirement  or  full  depreciation  of  certain  assets.    These  decreases  were  partially  offset  by  an 
increase of approximately $50 million primarily resulting from our newbuild ultra-deepwater drillships placed into service in the two-year 
period ended December 31, 2017. 

General  and  administrative  expense  decreased  for  the  year  ended  December 31,  2017  compared  to  the  year  ended 
December 31,  2016  primarily  due  to  the  following:  (a) approximately  $10 million  of  reduced  personnel  costs  and  (b) approximately 
$4 million of reduced professional fees. 

Loss  on  impairment  or  disposal  of  assets—In  the  year  ended  December 31,  2017,  we  recognized  losses  related  to  the 
following: (a) $1.4 billion associated with the impairment of certain assets classified as held for sale and (b) $94 million associated with the 
impairment  of  our  midwater  floater  asset  group.    In  the  year  ended  December 31,  2016,  we  recognized  losses  related  to  the  following: 
(a) $52 million associated with the impairment of our deepwater floater asset group and (b) $41 million associated with the impairment of 
certain assets classified as held for sale. 

In the year ended December 31, 2017, loss on disposal of assets was primarily due to the sale of 10 high-specification jackups 

and novation of the contracts relating to the construction of five high-specification jackups, together with related assets. 

Other income and expense—Interest expense, net of amounts capitalized,  increased in the year ended December 31, 2017 
compared  to  the  year  ended  December 31,  2016,  primarily  due  to  the  following:  (a) approximately  $168 million  resulting  from  new  debt 
issued in the two-year period ended December 31, 2017, (b) approximately $63 million resulting from reduced interest costs capitalized for 
our  newbuild  ultra-deepwater  drillships  that  commenced  operations  during  the  two-year period  ended  December 31,  2017  and 
(c) approximately $13 million resulting from downgrades to the credit rating for our senior unsecured long-term debt.  Partially offsetting 
these increases was a decrease of approximately $160 million resulting from debt retired during the two-year period ended December 31, 
2017. 

Loss on retirement of debt in the year ended December 31, 2017 resulted primarily from the following: (a) an aggregate loss of 
$48 million  resulting  from  the  retirement  of  notes  validly  tendered  in  the  2017 Tender  Offers  and  (b) an  aggregate  loss  of  $7 million 
resulting from debt redemptions and repurchases.  Gain on retirement of debt in the year ended December 31, 2016 resulted  primarily 
from the following: (a) an aggregate net gain of $104 million resulting from the retirement of notes validly tendered in cash tender offers 
completed August 1, 2016 (the “2016 Tender Offers”) and (b) an aggregate net gain of $44 million resulting from the retirement of notes 
repurchased in the open market. 

Other income, net, decreased in the year ended December 31, 2017 compared to the year ended December 31, 2016, primarily 
due to (a) $33 million of reduced income associated with our dual-activity patent and (b) $25 million of reduced income associated with the 
non-service component of net periodic benefit costs. 

Income  tax  expense—In  the  years  ended  December 31,  2017  and  2016,  our  effective  tax  rate  was  (3.1) percent  and 
11.5 percent,  respectively,  based  on  income  before  income  tax  expense.    Our  effective  tax  rate  decreased  primarily  due  to  losses  on 
impairment and disposal of assets with no tax benefit.  In the years ended December 31, 2017 and 2016, the effect of the various discrete 
period tax items represented a net tax benefit of $37 million and $50 million, respectively.  In the year ended December 31, 2017, such 
discrete items were primarily related to the tax benefit of changes in unrecognized tax benefits associated with tax positions taken in prior 
years, valuation allowances on deferred tax assets not expected to be realized, remeasurement of the U.S. deferred tax assets for a tax 
rate change as a result of the enactment of the 2017 Tax Act and deductions related to resolution of certain litigation matters related to 
Macondo well incident.  In the year ended December 31, 2016, such discrete items were primarily related to the tax benefit of changes in 
unrecognized tax benefits associated with tax positions taken in prior years and valuation allowances on deferred tax assets for losses not 
expected  to  be  realized.    In  the  years  ended  December 31,  2017  and  2016,  our  effective  tax  rate,  excluding  discrete  items,  was 
95.2 percent and 18.5 percent, respectively, based on income before income tax expense.  Our effective tax rate increased in the year 
ended  December 31,  2017  compared  to  the  year  ended  December 31,  2016,  primarily  due  to  the  following:  (a) changes  in  the  relative 
blend of income from operations in certain jurisdictions and (b) valuation allowances on deferred tax assets for losses not expected to be 
realized. 

As of December 31, 2017, our consolidated cumulative loss incurred over the recent three-year period, primarily due to losses on 
impairment and disposal of assets, represented significant objective negative evidence for our evaluation.  Such evidence, together with 
potential organizational changes that could alter our ability to realize certain deferred tax assets, has limited our ability to consider other 
subjective evidence, such as projected future contract activity.  As a result, we recorded an incremental valuation allowance of $110 million 
to  recognize  only  a  portion  of  our  U.S.  deferred  tax  assets  that  are  more  likely  than  not  to  be  recognized.    If  estimated  future  taxable 

AR-34 

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. 

Due  to  factors  related  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, 
2017, a significant portion of our income tax expense was generated in countries in which income taxes are imposed on gross revenues, 
with the most significant of these countries being Angola and India.  Conversely, the countries in which we incurred the most significant 
income taxes during this period that were based on income before income tax include Brazil, Switzerland, Norway, the U.K. and the U.S.  
Our  rig  operating  structures  further  complicate  our  tax  calculations,  especially  in  instances  where  we  have  more  than  one operating 
structure for the particular taxing jurisdiction and, thus, more than one method of calculating taxes depending on the operating structure 
utilized by the rig under the contract.  For example, two rigs operating in the same country could generate significantly different provisions 
for  income  taxes  if  they  are  owned  by  two different  subsidiaries  that  are  subject  to  differing  tax  laws  and  regulations  in  the  respective 
country of incorporation.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes. 

Liquidity and Capital Resources 

Sources and uses of cash 

At  December 31,  2018,  we  had  $2.2 billion  in  unrestricted  cash  and  cash  equivalents  and  $429 million  in  restricted  cash  and 
cash equivalents.  In the year ended December 31, 2018, our primary sources of cash were as follows: (1) net cash proceeds from the 
issuance of debt, (2) net cash provided by operating activities and (3) proceeds from maturities of unrestricted and restricted short-term 
investments.    Our  primary  uses  of  cash  were  as  follows:  (a) repayments  of  debt,  (b) cash  paid  in  business  combinations,  net  of  cash 
acquired,  (c) capital  expenditures,  primarily  associated  with  our  newbuild  construction  projects,  (d) deposits  into  restricted  short-term 
investments,  (e) investments  in  unconsolidated  affiliates,  and  (e) payments  to  terminate  certain  derivative  instruments  assumed  in  the 
Songa acquisition.

Net  cash  provided  by  operating  activities  decreased  primarily  due  to  the  following:  (i)  proceeds  of  $408 million  received  from 
customers for early terminations or cancellations of drilling contracts in the year ended December 31, 2017 with no comparable activity in 
the current year and (ii) increased cash used in our operations, including for increased cash interest payments and three rig reactivations.

Net cash used in investing activities increased primarily due to the following: (i) cash used in business combinations, net of cash 
acquired,  with  no  comparable  activity  in  the  year  ended  December 31,  2017,  (ii) reduced  net  proceeds  from  disposal  of  assets  and

Net cash used in financing activities decreased primarily due to the following: (i) increased net cash proceeds from the issuance 
of the 7.25% Senior Notes and the 2018 Senior Secured Notes in the current year compared to net cash proceeds from the issuance of the 
5.52% senior secured notes due May 2022 (the “5.52%Senior Secured Notes”) and the 7.50% senior unsecured notes due January 2026 
(the “7.50% Senior Notes”) in the prior year and (ii) decreased cash used to repay debt, primarily associated with the 2017 Tender Offers 
in  the  year  ended  December 31,  2017  compared  to  cash  used  to  repay  debt,  primarily  associated  with  debt  assumed  in  the  Songa 
acquisition, in the year ended December 31, 2018, partially offset by (iii) cash used to settle and terminate certain derivative instruments 
acquired in the Songa acquisition in the year ended December 31, 2018 with no comparable activity in the prior year and (iv) decreased 
cash proceeds from investments restricted for financing activities. 

Sources and uses of liquidity 

Overview—We  expect  to  use  existing  unrestricted  cash  balances,  internally  generated  cash  flows,  borrowings  under  the 
Secured  Credit  Facility,  proceeds  from  the  disposal  of  assets  or  proceeds  from  the  issuance  of  additional  debt  to  fulfill  anticipated 
obligations, which may include capital expenditures, working capital and other operational requirements, scheduled debt maturities or other 
payments.  We may also consider establishing additional financing arrangements with banks or other capital providers.  Subject to market 
conditions and other factors, we may also be required to provide collateral for future financing arrangements.  In each case subject to then 
existing market conditions and to our then expected liquidity needs, among other factors, we may continue to use a portion of our internally 
generated cash flows and proceeds from asset sales to reduce debt prior to scheduled maturities through debt repurchases, either in the 
open market or in privately negotiated transactions, or through debt redemptions or tender offers. 

Our access to debt and equity markets may be limited due to a variety of events, including, among others, credit rating agency 
downgrades of our debt ratings, industry conditions, general economic conditions, market conditions and market perceptions of us and our 
industry.  The rating of our non-credit enhanced senior unsecured long-term debt (“Debt Rating”) is below investment grade.  Such Debt 
Rating has caused us to experience increased fees and interest rates under agreements governing certain of our senior notes.  Further 
downgrades  may  affect  or  limit  our  ability  to  access  debt  markets  in  the  future.    Our  ability  to  access  such  markets  may  be  severely 
restricted 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.  An economic downturn could have an impact on the lenders participating in our credit facilities or on 
our customers, causing them to fail to meet their obligations to us. 

Our internally generated cash flows are directly related to our business and the market sectors in which we operate.  If the drilling 
market were to deteriorate, or if we were to experience poor results in our operations, cash flows from operations may be reduced.  We 
have, however, continued to generate positive cash flows from operating activities over recent years and expect that such cash flows will 
continue to be positive over the next year. 

Business combinations—On December 5, 2018, we acquired Ocean Rig in a merger transaction, and as a result, Ocean Rig 
became our wholly owned subsidiary.  To complete the acquisition, we issued 147.7 million shares and made an aggregate cash payment 
of $1.2 billion. 

On January 30, 2018, we acquired an approximate 97.7 percent ownership interest in Songa.  On March 28, 2018, we acquired 
the remaining shares not owned by us through a compulsory acquisition under Cyprus law, and as a result, Songa became our wholly 
owned subsidiary.  To complete these transactions, we issued 68.0 million shares and issued $863 million aggregate principal amount of 
Exchangeable Bonds as further described below. 

Secured  Credit  Facility—In  June 2018,  we  entered  into  a  bank  credit  agreement,  which  established  a  $1.0 billion  Secured 
Credit  Facility,  which  is  scheduled  to  expire  on  the  earlier  of  (i) June 22,  2023  and  (ii) if  greater  than  $300 million  aggregate  principal 
amount of our 9.00% Senior Notes due July 2023 remain outstanding in April 2023, such date.  The Secured Credit Facility is guaranteed 
by  Transocean Ltd.  and  certain  subsidiaries.    The  Secured  Credit  Facility  is  initially  secured  by,  among  other  things,  a  lien  on  the 
floaters 
ultra-deepwater 
Transocean Barents  and  Transocean Spitsbergen.    The  Secured  Credit  Facility  contains  covenants  that,  among  other  things,  include 
maintenance  of  certain  guarantee  and  collateral  coverage  ratios,  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 borrow under the Secured Credit Facility, we must, at 

floaters  Deepwater Asgard,  Deepwater Invictus  and  Discoverer Inspiration  and 

the  harsh  environment

the time of the borrowing request, not be in default under the bank credit agreement 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.  We are also subject to various covenants under the indentures 
pursuant  to  which  our  public  debt  was  issued,  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,  our  capital  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 11,  2019,  we  had 
no borrowings outstanding, $27 million of letters of credit issued, and we had $1.0 billion of available borrowing capacity under the Secured 
Credit Facility.  See Notes to Consolidated Financial Statements—Note 8—Debt and Note 13—Commitments and Contingencies—Global 
Marine litigation. 

Investments in unconsolidated affiliates—In the year ended December 31, 2018, we made an aggregate cash investment of 
$107 million  in  unconsolidated  affiliates,  including  an  initial  investment  of  $91 million,  representing  a  33.0 percent  interest,  in  Orion 
Holdings  (Cayman) Limited  (“Orion”),  a  Cayman  Islands  company  formed  to  construct  and  own  the  newbuild  harsh  environment 
semisubmersible  Transocean Norge.    In  January 2019,  we  made  an  additional  $59 million  contribution  to  Orion,  and  we  agreed  to 
contribute  $33 million  in  January 2020.    The  total  purchase  price  for  the  rig,  under  construction  at  the  Jurong  Shipyard Pte Ltd.  in 
Singapore, is $500 million.  Additionally, we invested $16 million in other companies involved in researching and developing technology to 
improve automation in drilling and other activities. 

Debt issuances—On February 1, 2019, we issued $550 million aggregate principal amount of 6.875% senior secured notes due 
February 2027 (the “6.875 Senior Secured Notes”), and we received aggregate cash proceeds of $538 million, net of issue costs.   The 
indenture that governs the 6.875% Senior Secured Notes contains covenants that, among other things, limit the ability of our subsidiaries 
that own or operate the collateral rig Deepwater Poseidon to declare or pay dividends to their affiliates.  We may redeem all or a portion of 
the 6.875 Senior Secured Notes at any time prior to February 1, 2022 at a price equal to 100 percent of the aggregate principal amount 
plus a make-whole provision, and on or after February 1, 2022, at specified redemption prices. 

On October 25, 2018, we issued $750 million aggregate principal  amount of 7.25% Senior Notes, and we received aggregate 
cash  proceeds  of  $735 million,  net  of  issue  costs.    We  may  redeem  all  or  a  portion  of  the  7.25% Senior  Notes  at  any  time  prior  to 
November 1,  2021  at  a  price  equal  to  100 percent  of  the  aggregate  principal  amount  plus  a  make-whole  provision,  and  on  or  after 
November 1, 2021, at specified redemption prices. 

In  July 2018,  we  issued  $750 million  aggregate  principal  amount  of  the  5.875% Senior  Secured  Notes  and  $600 million 
aggregate  principal  amount  of  the  6.125% Senior  Secured  Notes,  and  we  received  aggregate  cash  proceeds  of  $733 million  and 
$586 million, respectively, net of discount and issue costs.  The indentures that govern the 2018 Senior Secured Notes contain covenants 
that,  among  other  things,  limit  the  ability  of  our  subsidiaries  that  own  or  operate  the  collateral  rigs  Transocean Enabler, 
Transocean Encourage  and  Deepwater Pontus  to  declare  or  pay  dividends  to  their  affiliates.    We  may  redeem  all  or  a  portion  of  the 
2018 Senior Secured Notes at a price equal to 100 percent of the aggregate principal amount plus a make-whole provision.  We will be 
required to redeem the notes at a price equal to 100 percent of the aggregate principal amount without a make-whole provision, upon the 
occurrence of certain events related to the collateral rigs and the related drilling contracts. 

In  connection  with 

the  Songa  acquisition  transactions,  we  issued  $863 million  aggregate  principal  amount  of  the 
0.50% exchangeable senior bonds due January 2023 as partial consideration for the acquisition of the acquired Songa shares and partial 
settlement  of  certain  Songa  indebtedness.    Holders  of  the  Exchangeable  Bonds  may  convert  the  notes  into  shares  of  Transocean Ltd. 
under certain circumstances at a rate of 97.29756 shares per $1,000 note, equivalent to a conversion price of $10.28 per share, subject to 
adjustment due to the occurrence of certain events. 

On October 17, 2017, we issued $750 million aggregate principal  amount of 7.50% Senior Notes, and we received aggregate 
cash  proceeds  of  $742 million,  net  of  issue  costs.    We  may  redeem  all  or  a  portion  of  the  7.50% Senior  Notes  at  any  time  prior  to 
January 15,  2021  at  a  price  equal  to  100 percent  of  the  aggregate  principal  amount  plus  a  make-whole  provision,  and  on  or  after 
January 15, 2021, at specified redemption prices. 

On  May 5,  2017,  we  issued  $410 million  aggregate  principal  amount  of  the  5.52% Senior  Secured  Notes,  and  we  received 
aggregate cash proceeds of $403 million, net of issue costs.  The note purchase agreement that governs the 5.52% Senior Secured Notes 
contains  covenants  that  limit  the  ability  of  our  subsidiaries  that  own  or  operate  Deepwater Conqueror  to  declare  or  pay  dividends  to 
affiliates.  We will be required to redeem or to offer to redeem the notes at a price equal to 100 percent of the aggregate principal amount, 
and,  under  certain  circumstances,  the  payment  of  a  make-whole  amount,  upon  the  occurrence  of  certain  events  related  to 
Deepwater Conqueror and the related drilling contract. 

Debt assumptions and repayments—In connection with the Songa acquisition, we assumed rights and obligations under credit 
agreements  establishing  two senior  secured  term  loan  facilities  (the  “Senior  Secured  Term  Loans”)  and  a  subscription  agreement 
establishing  a  junior  secured  bond  facility  (the  “Junior  Secured  Bonds”).    The  credit  agreements  and  subscription  agreement  for  the 
assumed  debt  contained  change  of  control  clauses,  for  which  we  received  waivers  from  the  lenders  that  were  scheduled  to  expire  on 
August 31, 2018.  On February 12, 2018, we served notice of our intent to call the Junior Secured Bonds.  In the year ended December 31, 

AR-37 

2018, we made an aggregate cash payment of $1.4 billion and $171 million to repay the borrowings under the Senior Secured Term Loans 
and the Junior Secured Bonds, respectively, and terminated the underlying agreements. 

In connection with the Songa acquisition, we assumed the indebtedness related to two bond loans (together, the “Bond Loans”), 
previously publicly traded on the Oslo stock exchange, and on March 14, 2018, we made a cash payment of NOK 345 million, equivalent 
to $44 million, to repay the Bond Loans.  We also assumed the rights and obligations under a credit agreement, which was due to expire 
on March 31, 2018, for a secured borrowing facility.  On February 2, 2018, we made a cash payment of $23 million to repay the borrowings 
outstanding under the secured borrowing facility and terminated the underlying credit agreement. 

Debt  tender  offers—On  February 5,  2019,  we  completed  the  2019 Tender  Offers  to  purchase  for  cash  up  to  $700 million 
aggregate purchase price of the 2019 Tendered Notes, subject to the terms and conditions specified in the related offer to purchase.  In 
January  and  February 2019,  as  a  result  of  the  2019 Tender  Offers,  we  made  an  aggregate  cash  payment  of  $521 million  to  settle  the 
validly tendered 2019 Tendered Notes. 

On July 11, 2017, we completed the 2017 Tender Offers to purchase for cash up to $1.5 billion aggregate principal amount of 
certain  notes  (the  “2017 Tendered  Notes”).    We  received  valid  tenders  from  holders  of  $1.2 billion  aggregate  principal  amount  of  the 
2017 Tendered Notes, and we made an aggregate cash payment of $1.3 billion to settle the 2017 Tendered Notes. 

Debt redemptions, repurchases and other repayments—In the year ended December 31, 2018, we repurchased in the open 
market  $95 million  aggregate  principal  amount  of  our  debt  securities  for  an  aggregate  cash  payment  of  $95 million.    In  the  year  ended 
December 31, 2017, we repurchased in the open market $156 million aggregate principal amount of our debt securities for an aggregate 
cash payment of $157 million. 

In  November 2017,  we  redeemed  the  outstanding  6.00% Senior  Notes  due  March 2018  and  the  7.375% Senior  Notes  due 
April 2018  with  aggregate  principal  amounts  of  $319 million  and  $82 million,  respectively,  and  we  made  an  aggregate  cash  payment  of 
$407 million. 

Debt scheduled maturities—On the scheduled maturity date of October 16, 2017, we made a cash payment of $152 million to 

repay the outstanding 2.50% Senior Notes due October 2017, at a price equal to 100 percent of the aggregate principal amount. 

Derivative instruments—In connection with the Songa acquisition, we acquired certain currency swaps that were denominated 
in  Norwegian kroner.    In  February 2018,  we  made  an  aggregate  cash  payment  of  $92 million  in  connection  with  the  settlement  and 
termination of the currency swaps. 

Litigation  settlements—On  May 29,  2015,  together  with  the  Plaintiff  Steering  Committee  (the  “PSC”),  we  filed  a  settlement 
agreement  (the  “PSC  Settlement  Agreement”)  in  which  we  agreed  to  pay  a  total  of  $212 million,  plus  up  to  $25 million  for  partial 
reimbursement of attorneys’ fees.  In exchange for these payments, the two classes of plaintiffs agreed to release all respective claims 
against us.  On February 15, 2017, the U.S. District Court for the Eastern District of Louisiana (the “MDL Court”) entered a final order and 
judgement approving the PSC Settlement Agreement, which is no longer subject to appeal.  In June 2016 and August 2015, we made a 
cash  deposit  of  $25 million  and  $212 million,  respectively,  into  an  escrow  account  established  by  the  MDL Court  for  the  settlement.    In 
November 2017,  the  MDL Court  released  $25 million  from  the  escrow  account  for  payment  of  attorneys’  fees.    In  November 2018,  the 
MDL Court released $58 million from the escrow account as the first installment to the plaintiffs.  As of February 11, 2019, the aggregate 
balance of our escrow account was $156 million.  We expect the remaining funds to be released in March 2019. 

Pursuant  to  a  cooperation  guilty  plea  agreement  by  and  among  the  U.S.  Department  of  Justice  (“DOJ”)  and  certain  of  our 
affiliates, which was accepted by the court on February 14, 2013, we agreed to pay a criminal fine of $100 million and to consent to the 
entry of an order requiring us to pay $150 million each to the National Fish & Wildlife Foundation and the National Academy of Sciences.  
In the year ended December 31, 2017, we made the final scheduled cash payment of $60 million. 

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  an  amount  of  our  shares  for  cancellation  with  an  aggregate  purchase  price  of  up  to 
CHF 3.5 billion.  On February 12, 2010, our board of directors authorized our management to implement the share repurchase program.  
At February 11, 2019, the authorization remaining under the share repurchase program was for the repurchase of up to CHF 3.2 billion, 
equivalent to approximately $3.3 billion, of our outstanding shares.  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.”

Includes scheduled installments of principal and imputed interest on our capital lease obligation. 

(a) 
(b)  We have long-term service agreements with certain original equipment manufacturers to provide services and parts related to our pressure control 
systems,  thrusters,  top  drives  and  other  equipment.    The  future  payments  required  under  our  service  agreements  were  estimated  based  on  our 
projected operating activity and may vary based on actual operating activity. 

(c)  As  of  December 31,  2018,  our  defined  benefit  pension  and  other  postemployment  plans  represented  an  aggregate  liability  of  $362 million, 
representing the aggregate projected benefit obligation, net of the aggregate fair value of plan assets.  The carrying amount of this liability is affected 
by  net  periodic  benefit  costs,  funding  contributions,  participant  demographics,  plan  amendments,  significant  current  and  future  assumptions,  and 
returns on plan assets.  Due to the uncertainties resulting from these factors and since the carrying amount is not representative of future liquidity 
requirements, we have excluded this amount from the contractual obligations presented in the table above.  See Notes to Consolidated Financial 
Statements—Note 12—Postemployment Benefit Plans. 
As of December 31, 2018, our unrecognized tax benefits related to uncertain tax positions, net of prepayments, represented a liability of $514 million.  
Although  a  portion  of  these  might  settle  or  reverse  in  the  coming  year,  there  is  a  high  degree  of  uncertainty  regarding  the  timing  of  future  cash 
outflows  associated  with  the  liabilities  recognized  in  this  balance,  we  are  unable  to  make  reasonably  reliable  estimates  of  the  period  of  cash 
settlement with the respective taxing authorities, and we excluded this amount from the contractual obligations presented in the table above.  See 
Notes to Consolidated Financial Statements—Note 10—Income Taxes. 

Other  commercial  commitments—We  have  other  commercial  commitments  that  we  are  contractually  obligated  to  fulfill  with 
cash under certain circumstances.  These commercial commitments include 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.  Standby letters of 
credit are issued under various committed and uncommitted credit lines, some of which require cash collateral.  At December 31, 2018, the 
aggregate cash collateral held by banks for letters of credit was $5 million.  The obligations that are the subject of these standby letters of 
credit and surety bonds are primarily geographically concentrated in Brazil and India.  Obligations under these standby letters of credit and 
surety bonds are not normally called, as we typically comply with the underlying performance requirement. 

At December 31, 2018, 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, 
2018,  the  captive  insurance  company  held  cash  and  cash  equivalents  of  $241 million,  and  such  balance  is  expected  to  range  from 
$50 million to $265 million through December 31, 2019.  The balance of actual cash and cash equivalents held by the captive insurance 
company varies, depending on the premiums paid to the captive insurance company and the timing and number of claims or dividends 
paid by the captive insurance company. 

Drilling fleet 

Expansion—From time to time, we review possible acquisitions of businesses and drilling rigs and 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.  We may commit to such investment without first obtaining customer contracts.  Any acquisition, 
upgrade or new rig construction 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 secure drilling contracts for rigs under construction could have an adverse effect on 
our results of operations or cash flows.

On December 5, 2018, we completed our acquisition of Ocean Rig in a merger transaction.  In connection with the Ocean Rig 
acquisition,  we  acquired  (i) 11 mobile  offshore  drilling  units,  including  nine ultra-deepwater  floaters  and  two harsh  environment  floaters, 
and (ii) the contracts relating to the construction of two ultra-deepwater drillships.  On January 30, 2018, we completed our acquisition of 
an approximate 97.7 percent ownership interest in Songa, and on March 28, 2018, we acquired the remaining shares not owned by us, 
and as a result, Songa became our wholly owned subsidiary.  In connection with the Songa acquisition, we acquired seven mobile offshore 
drilling  units,  including  five harsh  environment  floaters  and  two midwater  floaters.    See  Notes  to  Consolidated  Financial  Statements—
Note 4—Business Combinations. 

We hold a 33.0 percent interest in Orion Holdings (Cayman) Limited, a Cayman Islands company formed to construct and own 
the  newbuild  harsh  environment  semisubmersible  Transocean Norge.    In  May 2018  and  January 2019,  we  made  an  aggregate  cash 
investment  of  $91 million  and  $59 million,  respectively.    The  total  purchase  price  for  the  rig,  under  construction  at  the  Jurong 
Shipyard Pte Ltd.  in  Singapore,  is  $500 million.    The  Moss  Maritime CS60  design  is  considered  among  the  most  capable  newbuild 
semisubmersibles  in  the  world.    We  expect  to  operate  the  rig,  through  one  of  our  wholly  owned  subsidiaries,  under  a  six-well  drilling 
contract that is expected to commence in July 2019.  See Notes to Consolidated Financial Statements—Note 1—Business. 

In the years ended December 31, 2018 and 2017, we made capital expenditures of $184 million and $497 million, respectively, 
including  $75 million  and  $397 million,  respectively,  for  our  major  construction  projects.    As  of  December 31,  2018,  the  historical  and 
projected capital expenditures, capitalized interest and other cash or non-cash capital additions for our ongoing major construction projects 
were as follows:

(a)  Ocean Rig Santorini  and  Ocean Rig Crete,  two  ultra-deepwater  drillships  under  construction  at  Samsung  Heavy  Industries Co., Ltd.  shipyard  in 
South  Korea,  do  not  yet  have  drilling  contracts  and  are  expected  to  be  delivered  in  the  third quarter  of  2019  and  the  third quarter  of  2020, 
respectively.  Included in the above table, upon delivery of Ocean Rig Santorini and Ocean Rig Crete in the third quarter of 2019 and third quarter of 
2020, respectively, our expected remaining obligations to the shipyard will be $360 million and $520 million, respectively.  The shipyard has agreed 
to finance the expected remaining obligations at an interest rate of three percent per annum, payable semiannually, with principal due at maturity in 
June 2023 and January 2024, respectively. 

(b)  Our unnamed ultra-deepwater drillship under construction at the Jurong Shipyard Pte Ltd. in Singapore does not yet have a drilling contract and is 

expected to be delivered in the second quarter of 2020. 

(c)  Our unnamed ultra-deepwater drillship under construction at the Jurong Shipyard Pte Ltd. in Singapore is expected to commence operations in the 
fourth quarter of 2021.  The projected capital additions include estimates for an upgrade for two 20,000 pounds per square inch blowout preventers 
and other equipment required by our customer, Chevron. 

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 through available cash balances, cash generated from operations and asset sales and 
financing arrangements with banks or other capital providers.  We also have available credit under our Secured Credit Facility (see “—
Sources and uses of liquidity”).  Economic conditions could impact the availability of these sources of funding. 

Dispositions—From  time  to  time,  we  may  review  the  possible  disposition  of  non-strategic  drilling  units.    Considering  recent 
market conditions, we have committed to plans to sell  certain lower-specification drilling units for scrap value.  During the years  ended 
December 31, 2018, 2017 and 2016, we identified eight, seven and seven such drilling units, respectively, that we have sold or intend to 
sell for scrap value.  In February 2019, we committed to plans to sell two additional drilling units for scrap value.  We continue to evaluate 
the drilling units in our fleet and may identify additional lower-specification drilling units to be sold for scrap value. 

During  the  year ended  December 31,  2018,  we  completed  the  sale  of  six ultra-deepwater  floaters,  one deepwater  floater  and 
one midwater floater, along with related assets, and we received net cash proceeds of $36 million.  On May 31, 2017, we completed the 
sale of 10 high-specification jackups and novated the contracts relating to the construction of five high-specification jackups, together with 
related  assets.    In  the  year ended  December 31,  2017,  as  a  result  of  this  transaction,  we  received  aggregate  net  cash  proceeds  of

floaters, along with related assets, and we received net cash proceeds of $22 million. 

Off-Balance Sheet Arrangements 

Orion  Holdings  (Cayman) Limited  is  an  unconsolidated  affiliate  formed  to  construct  and  own  the  newbuild  harsh  environment 
semisubmersible Transocean Norge.  The total purchase price for the rig, under construction at the Jurong Shipyard Pte Ltd. in Singapore, 
is $500 million.  In January 2019, we made an additional $59 million contribution and we agreed to make another $33 million contribution in 
January 2020.    Orion  Holdings  (Cayman) Limited  may  enter  into  financing  arrangements  to  fund  its  capital  requirements  for  the 
construction of the newbuild unit. 

Related Party Transactions 

As  of  December 31,  2018,  we  did  not  have  any  material  related  party  transactions  that  were  not  in  the  ordinary  course  of 

business. 

Other Matters 

Regulatory matters 

Consent Decree—Under the civil consent decree (the “Consent Decree”), which resolved the claim by the U.S. for civil penalties 
under the Clean Water Act, we agreed to undertake certain actions, including enhanced safety and compliance actions when operating in 
U.S.  waters.    We  also  agreed  to  pay,  and  have  satisfied  our  obligations  to  pay,  civil  penalties  of  $1.0 billion  plus  interest.    The 
Consent Decree  requires  us  to  submit  and  make  publicly  available  certain  plans,  reports  and  other  submissions.    One  such  plan  is  a 
performance plan approved on January 2, 2014, that contains, among other things, interim milestones for actions in specified areas and 
schedules  for  reports  required  under  the  Consent Decree.    Additionally,  as  required,  we retained  an  independent  auditor  to review  and 
report to the DOJ our compliance with the Consent Decree and an independent process safety consultant to review, report and assist with 
the process safety requirements of the Consent Decree.  On January 2, 2019, as permitted under the Consent Decree, we submitted an 
official termination request to the U.S.  On  February 6, 2019, the U.S. submitted a joint  stipulation and proposed order (the “Order”) to 
terminate the Consent Decree to the U.S. District Court for the Eastern District of Louisiana (the “Court”), and on February 13, 2019, the 
Court entered the Order.  Accordingly, the Consent Decree is terminated and has no further force or effect on the Company. 

Other regulatory matters—In addition, 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 13—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.  From time to time, we may identify changes to previously evaluated tax positions 
that could result in adjustments to our recorded assets and liabilities.  Although we are unable to predict the outcome of these changes, we 
do not expect the effect, if any, resulting from these adjustments to have a material adverse effect on our consolidated financial position, 
results of operations or cash flows.  We file federal and local tax returns in several jurisdictions throughout the world.  Tax authorities in 
certain jurisdictions are examining our tax returns and in some cases have issued assessments.  We are defending our tax positions in 
those  jurisdictions.    While  we  cannot  predict  or  provide  assurance  as  to  the  final  outcome  of  these  proceedings,  we  do  not  expect  the 
ultimate liability to have a material adverse effect on our consolidated financial position or results of operations, although it may have a 
material adverse effect on our consolidated cash flows.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes. 

Critical Accounting Policies and Estimates 

Overview—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, refer to our Notes to Consolidated Financial Statements—Note 2—Significant Accounting Policies. 

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,  assets  held  for  sale,  goodwill,  contingencies, 
postemployment benefit plans, materials and supplies obsolescence, share-based compensation and allowance for doubtful accounts.  We 
base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, 

AR-41 

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. 

Income taxes—We are a Swiss corporation, operating through our various subsidiaries in a number of countries throughout the 
world.    We  provide  for  income  taxes  based  on  the  tax  laws  and  rates  in  the  countries  in  which  we  operate  and  earn  income.    The 
relationship between the provision for or benefit from income taxes and our income or loss before income taxes can vary significantly from 
period to period because the countries in which we operate have taxation regimes that vary with respect to the nominal tax rate and the 
availability  of  deductions,  credits  and  other  benefits.    Consequently,  our  income  tax  expense  does  not  change  proportionally  with  our 
income before income taxes.  Variations also arise when income earned and taxed in a particular country or countries fluctuates from year 
to year. 

Our annual tax provision is based on expected taxable income, statutory rates and tax planning opportunities available to us in 
the various jurisdictions in which we operate.  The determination of our annual tax provision and evaluation of our tax positions involves 
interpretation of tax laws in the various jurisdictions and requires significant judgment and 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 of operations 
or profitability in each jurisdiction.  Additionally, we operate in many jurisdictions where the tax laws relating to the offshore drilling industry 
are not well developed.  Although our annual tax provision is based on the best information available at the time, a number of years may 
elapse before the tax liabilities in the various jurisdictions are ultimately determined. 

We establish liabilities for estimated tax exposures in our jurisdictions of operation, and the provisions and benefits resulting from 
changes  to  those  liabilities  are  included  in  our  annual  tax  provision  along  with  related  interest.    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, 
2018 and 2017, the liability for estimated tax exposures in our jurisdictions of operation was approximately $514 million and $309 million, 
respectively. 

We are currently undergoing examinations in a number of taxing jurisdictions for various fiscal 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.    We  do  not  believe  it  is  possible  to  reasonably  estimate  the  future  impact  of  changes  to  the 
assumptions and estimates related to our annual tax provision because changes to our tax liabilities are dependent on numerous factors 
that cannot be reasonably projected.  These factors include, 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. 

We do not provide for taxes on unremitted earnings of subsidiaries when we consider such earnings to be indefinitely reinvested.  
We recognize deferred taxes related to the earnings of certain subsidiaries that we do not consider to be indefinitely reinvested or that will 
not be indefinitely reinvested in the future.  If we were to make a distribution from the unremitted earnings of these subsidiaries, we could 
be subject to taxes payable to various jurisdictions.  If facts and circumstances cause us to change our expectations regarding future tax 
consequences,  the  resulting  adjustments  to  our  deferred  tax  balances  could  have  a  material  effect  on  our  consolidated  statement  of 
financial position, results of operations or cash flows.  If we were to distribute from the unremitted earnings of these subsidiaries, we could 
be subject to taxes payable to various jurisdictions. 

Estimates, judgments and assumptions are required in determining whether deferred tax assets will be fully or partially realized.  
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.  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. 

The 2017 Tax Act imposes a one-time transition tax on certain unremitted earnings and profits of our non-U.S. subsidiaries that 
are owned by U.S. subsidiaries.  At December 31, 2017, we did not have the necessary information available, prepared and analyzed to 
develop a reasonable estimate of the transition tax.  In the year ended December 31, 2018, we completed our evaluation of the post-1986 
earnings and profits for the non-U.S. subsidiaries of our U.S. subsidiaries and determined the amount of those earnings held in cash and 
other assets necessary to determine the transition tax, and we recorded income tax expense of $103 million for estimated transition taxes 
and an income tax benefit of $16 million for the estimated effect on the utilization of foreign tax credits.  The transition tax had an effect on 
the utilization of our foreign tax credits and net operating losses generated in the U.S., which had an effect on our valuation allowance 
analysis  related  to  those  deferred  tax  assets.    Although  we  have  completed  our  analysis  and  recorded  the  resulting  impact  of  the 
2017 Tax Act, the U.S. Congress or Treasury may introduce clarifications, modification or amendments that could cause us to make further 
adjustments in future periods. 

We continually evaluate strategies that could allow for the future utilization of our deferred tax assets.  During the years ended 
December 31, 2018 and 2017, in evaluating our projected realizability of deferred tax assets, we considered our consolidated cumulative 

AR-42 

loss incurred over the recent three-year period, which is primarily due to losses on impairment and disposal of assets, which 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. 

Business  combinations—In  connection  with  our  acquisition  of  Songa  and  Ocean  Rig,  we  applied  the  acquisition  method  of 
accounting.  Accordingly, we recorded the acquired assets and assumed liabilities at fair value and recognized goodwill to the extent the 
consideration  transferred  exceeded  the  fair  value  of  the  net  assets  acquired.    To  the  extent  the  fair  value  of  the  net  assets  acquired 
exceeded the consideration transferred, we recognize a bargain purchase gain.  We estimate the fair values of the acquired assets and 
assumed liabilities as of the acquisition date, and our estimates continue to be subject to adjustment based on our final assessments of the 
fair values of property and equipment, intangible assets, liabilities and our evaluation of tax positions and contingencies.  We will complete 
our final assessments of the fair values of the acquired assets and assumed liabilities and our final evaluations of uncertain tax positions 
and contingencies within one year of the acquisition date. 

Our estimates of fair value of property and equipment and contract intangibles require us to use significant unobservable inputs, 
representative of a Level 3 fair value measurement, such as future commodity prices, projected demand for our services, rig utilization, 
dayrates, remaining useful lives of the rigs and discount rates.  We also consider a sales comparison approach from the perspective of 
potential buyers and sellers of comparable assets.  The valuation of a rig and our estimate of the remaining useful life can also vary based 
on  the  rig  design,  condition  and  particular  equipment  configuration.    We  estimate  the  fair  value  of  drilling  contracts  by  comparing  the 
contractual dayrates over the remaining firm contract term and option periods relative to the projected market dayrates as of the acquisition 
date.  We estimate the fair value of construction contracts by comparing the contractual future payments and terms relative to the market 
payments  and  terms  as  of  the  acquisition  date.    It  can  be  difficult  to  determine  the  fair  value  based  on  the  cyclicality  of  our  business, 
demand  for  offshore  drilling  rigs  in  different  markets  and  changes  in  economic  conditions.    See  Notes  to  Consolidated  Financial 
Statements—Note 4—Business Combinations. 

Property and equipment—The carrying amount of property and equipment is subject to various estimates, assumptions, and 
judgments related to capitalized costs, useful lives and salvage values and impairments.  At December 31, 2018 and 2017, the carrying 
amount  of  our  property  and  equipment  was  $20.4 billion  and  $17.4 billion,  respectively,  representing  80 percent  and  78 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 and depreciation expense of 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.  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.  
At  December 31,  2018,  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  $40 million  and  a  hypothetical  one-year  decrease  would  cause  an  increase  in  our  annual 
depreciation expense of approximately $64 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 or when carrying amounts of assets held for sale 
exceed  fair  value  less  cost  to  sell.    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 move rigs from an oversupplied market sector to a more lucrative and undersupplied market sector 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, harsh environment floaters and midwater 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 

AR-43 

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  a  Level 3  fair  value  measurement,  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,  2017,  we  recognized  a  loss  of  $94 million  ($93 million,  net  of  tax)  associated  with  the 
impairment of the midwater floater asset group.  In the year ended December 31, 2016, we recognized a loss of $52 million, which had no 
tax effect, associated with the impairment of the deepwater floater asset group.  In the years ended December 31, 2018, 2017 and 2016, 
we  recognized  a  loss  of  $999 million,  $1.4 billion  and  $41 million,  respectively,  associated  with  the  impairment  of  assets  that  we 
determined  were  impaired  at  the  time  we  classified  such  assets  as  assets  held  for  sale.    See  Notes  to  Consolidated  Financial 
Statements—Note 6—Drilling Fleet. 

Contingencies—We  perform  assessments  of  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.  We recognize corresponding assets for loss contingencies 
that  we  believe  are  probable  of  being  recovered  through  insurance.    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 liabilities for legal costs as they are incurred, and we recognize a corresponding asset for 
those  legal  costs  only  if  we  expect  such  legal  costs  to  be  recovered  through  insurance.    Our  estimates  involve  a  significant  amount  of 
judgement.  Actual results may differ from our estimates. 

We  have  recognized  a  liability  for  estimated  loss  contingencies  associated  with  litigation  and  investigations  resulting  from  the 
Macondo well incident that we believe are probable and for which a reasonable estimate can be made.  As of December 31, 2018 and 
2017, the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was 
$158 million and $219 million, respectively, recorded in other current liabilities, the majority of which is related to our settlement with the 
PSC.  See Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies. 

Goodwill  impairment—We  conduct  impairment  testing  for  our  goodwill  annually  as  of  October 1  and  more  frequently,  on  an 
interim basis, when an event occurs or circumstances change that may indicate a reduction in the fair value of a reporting unit is below its 
carrying amount.  Before testing goodwill, we consider whether or not to first assess qualitative factors to determine whether the existence 
of  events  or  circumstances  leads  to  a  determination  that  it  is  more  likely  than  not  that  the  fair  value  of  a  reporting  unit  is  less  than  its 
carrying  amount  and  whether  an  impairment  test  is  required.    If,  as  the  result  of  our  qualitative  assessment,  we  determine  that  an 
impairment test is required, or, alternatively, if we elect to forgo the qualitative assessment, we test goodwill for impairment by comparing 
the carrying amount of the reporting unit, including goodwill, to the fair value of the reporting unit.  We test goodwill at the reporting unit 
level, which is defined as an operating segment or a component of an operating segment that constitutes a business for which financial 
information  is  available  and  is  regularly  reviewed  by  management.    We  have  determined  that  contract  drilling  services  is  our  single 
reporting unit for this purpose. 

To estimate the fair value of our reporting unit, we apply a variety of valuation methods, incorporating the income, market and 
cost approaches.  We estimate fair value using discounted cash flows, publicly traded company multiples and acquisition multiples.  To 
develop the projected cash flows associated with our contract drilling services reporting unit, which are based on estimated future dayrates 
and  rig  utilization,  we  consider  key  factors,  including  assumptions  regarding  future  commodity  prices,  credit  market  conditions  and  the 
effect  these  factors  may  have  on  our  contract  drilling  operations  and  the  capital  expenditure  budgets  of  our  customers.    We  discount 
projected cash flows using a long-term weighted-average cost of capital, which is based on our estimate of the investment returns that 
market participants would require for our reporting unit.  To develop the publicly traded company multiples, we  gather available market 
data for companies with operations similar to our reporting unit and publicly available information for recent acquisitions in the marketplace.  
We may weigh the approaches, under certain circumstances, when a single approach produces inconclusive results or when results from 
multiple approaches deviate significantly. 

Our estimates of fair value require us to use significant unobservable inputs, representative of a Level 3 fair value measurement, 
including assumptions related to the future performance of our contract drilling services reporting unit, such as future commodity prices, 
projected demand for our services, rig utilization and dayrates.  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  in  a  reporting  unit’s  fair  value  calculations  could  result  in  an  estimate  that  is  significantly  below  its 
carrying amount, which may indicate its goodwill is impaired.  In the year ended December 31, 2018, as a result of an interim goodwill test, 
we  recognized  an  aggregate  loss  of  $462 million,  which  had  no  tax  effect,  associated  with  the  impairment  of  the  full  balance  of  our 

AR-44 

goodwill.    See  Notes  to  Consolidated  Financial  Statements—Note 3—Accounting  Standards  Updates,  Note 4—Business  Combinations

At  December 31,  2018  and  2017,  the  fair  value  of  our  debt,  presented  above  was  $9.2 billion  and  $7.5 billion,  respectively.  
During  the  year  ended  December 31,  2018,  the  fair  value  of  our  debt  increased  by  $1.7 billion  due  to  the  following:  (a) an  increase  of 
approximately  $2.1 billion  due  to  the  issuance  of  Exchangeable  Bonds  and  the  2018 Senior  Secured  Notes,  (b) an  increase  of 
approximately  $661 million  due  to  the  issuance  of  7.25% Senior  Notes,  partially  offset  by  (c) a  decrease  of  $363 million  due  to  the 
repayment  of  debt  in  scheduled  installments  and  (d) a  decrease  of  approximately  $753 million  due  to  changes  in  market  prices  for  our 
outstanding debt.  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 

would earn commensurately higher rates of return if interest rates increase. 

Currency  exchange  rate  risk—We  are  exposed  to  currency  exchange  rate  risk  primarily  associated  with  our  international 
operations.  Our primary risk management strategy for currency exchange rate risk involves structuring customer contracts to provide for 
payment in both U.S. dollars, which is our functional currency, and local currency.  The portion denominated in local currency is based on 
our anticipated local currency needs over the contract term.  Due to various factors, including customer contract terms, local banking laws, 
other statutory requirements, local currency convertibility and the impact of inflation on local costs, actual local currency needs may vary, 
resulting in exposure to currency exchange rate risk.  We may occasionally enter into forward exchange contracts to satisfy anticipated 
local currency needs.  The effect of fluctuations in currency exchange rates caused by our international operations generally has not had a 
material impact on our overall operating results.  See Notes to Consolidated Financial Statements—Note 19—Risk Concentration.

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, 2018.  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.    On  December 5,  2018,  we  completed  our  acquisition  of  Ocean  Rig  UDW Inc.  (“Ocean  Rig”).  
Management has excluded Ocean Rig, which accounted for 11 percent of the Company’s total assets as of December 31, 2018, from its 
assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting.    Based  on  this  assessment,  management 
believes that the Company maintained effective internal control over financial reporting as of December 31, 2018. 

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, 2018, 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, 2018, based on the COSO criteria. 

As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and 
conclusion  on  the  effectiveness  of  internal  control  over  financial  reporting  did  not  include  the  internal  controls  of  Ocean Rig,  which  is 
included  in  the  2018 consolidated  financial  statements  of  the  Company  and  constituted  11 percent  of  total  assets  as  of  December 31, 
2018.  Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over 
financial reporting of Ocean Rig. 

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, 2018 and 2017, and the related consolidated statements of operations, 
comprehensive income (loss), equity and cash flows for each of the three years in the period ended December 31, 2018, and the related 
notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 19, 2019, 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, 
2018 and 2017, the related consolidated statements of operations, comprehensive income (loss), equity and cash flows for each of the 
three years  in  the  period  ended  December 31,  2018,  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, 2018 and 2017, and the results of its operations and 
its cash flows for each of the three years in the period ended December 31, 2018, 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, 2018, 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 19, 2019 expressed an unqualified opinion thereon. 

Basis for Opinion 

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.

Transocean Ltd., Steinhausen  

Zurich, February 19, 2019 

Report of the statutory auditor on the consolidated financial statements 

Opinion 
As statutory auditor, we have audited the consolidated financial statements of Transocean Ltd. and its subsidiaries (the Company), which 
comprise  the  consolidated  balance  sheets  as  of  December 31,  2018  and  2017,  and  the  related  consolidated  statements  of  operations, 
comprehensive  income  (loss),  equity,  cash  flows,  and  notes  to  the  consolidated  financial  statements  for  each  of  the  three years  in  the 
period  ended  December 31,  2018  (pages  AR-52  –  AR-89).    In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all 
material respects, the consolidated financial position of the Company as of December 31, 2018 and 2017, and the consolidated results of 
its operations and its cash flows for each of the three years in the period ended December 31, 2018, in accordance with U.S. generally 
accepted accounting principles and comply with Swiss law. 

Board of Directors’ Responsibility 
The  Board  of  Directors  is  responsible  for  the  preparation  of  the  consolidated  financial  statements  in  accordance  with  U.S.  generally 
accepted accounting principles and the requirements of Swiss law.  This responsibility includes designing, implementing and maintaining 
an  internal  control  system  relevant  to  the  preparation  of  consolidated  financial  statements  that  are  free  from  material  misstatement, 
whether due to fraud or error.  The Board of Directors is further responsible for selecting and applying appropriate accounting policies and 
making accounting estimates that are reasonable in the circumstances. 

Auditor’s Responsibility 
Our responsibility is to express an opinion on these consolidated financial statements based on our audits.  We are a public accounting 
firm and are required to be  independent with respect to the Company.  We conducted our audits  in accordance with Swiss  law, Swiss 
Auditing Standards and the standards of the Public Company  Accounting Oversight Board (United States) (PCAOB).  Those standards 
require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free 
from material misstatement, whether due to fraud or error. 

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

Report on key audit matters based on the circular 1/2015 of the Federal Audit Oversight Authority 
Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial 
statements of the current period.  These matters were addressed in the context of our audit of the consolidated financial statements as a 
whole,  and  in  forming  our  opinion  thereon,  and  we  do  not  provide  a  separate  opinion  on  these  matters.    For  each  matter  below,  our 
description of how our audit addressed the matter is provided in that context. 

We have fulfilled the responsibilities described in the Auditor’s responsibility section of our report, including in relation to these matters. 
Accordingly,  our  audit  included  the  performance  of  procedures  designed  to  respond  to  our  assessment  of  the  risks  of  material 
misstatement of the consolidated financial statements.  The results of our audit procedures, including the procedures performed to address 
the matters below, provide the basis for our audit opinion on the consolidated financial statements.

Business combinations 

Area of 
emphasis 

As  described  in  Note 4  to  the  consolidated  financial  statements,  during  2018  the  Company  acquired  Songa 
Offshore SE for net consideration of USD 1.8 billion and Ocean Rig UDW Inc. for a net consideration of USD 
2.5 billion. 

Auditing the accounting for the Company's 2018 acquisitions of Songa Offshore SE and Ocean RIG UDW Inc. 
involved a high degree of subjectivity in evaluating management's estimates, such as the recognition of the fair 
value of assets acquired and liabilities assumed. 

Our audit 
response 

Our  audit  procedures  related  to  the  key  audit  matter  of  business  combinations  included  the  following 
procedures:  

We tested the Company’s controls over the accounting for acquisitions, such as controls over the recognition 
and  measurement  of  assets  acquired,  liabilities  assumed,  and  consideration  paid  and  payable,  including 
convertible  instruments.    We  read  the  purchase  agreements,  evaluated  the  significant  assumptions  and 
methods used in developing the fair value estimates, and tested the recognition of (1) the assets acquired and 
liabilities assumed at fair value; (2) the identifiable acquired intangible assets at fair value; and (3) goodwill or 
bargain purchase gain measured as a residual. 

We evaluated, among other things, whether the significant assumptions, including forecasted day rates and 
utilization,  discount  rates,  estimated  useful  lives,  and  the  growth  rate  used  in  valuing  the  rigs  and  related 
contract  intangibles  were  appropriate,  which  are  affected  by  expectations  about  future  market  or  economic 
conditions.  Specifically, when evaluating the assumptions related to the forecasted day rates and utilization, 
we compared the assumptions to similar fixtures in the market and considered whether they were consistent 
with evidence obtained in other areas of the audit, such as assumptions used by the Company in its budget.  

Valuation of Goodwill of the Contract Drilling Services reporting unit 

Area of 
emphasis 

At December 31, 2018, the Company had no goodwill and recorded an impairment of USD 462 million during 
the year-ended December 31, 2018.  As discussed in Note 7 of the consolidated financial statements, goodwill 
is tested for impairment at least annually, or on an interim basis if indicators are present, at the reporting unit 
level.  The Company’s goodwill is initially assigned to its reporting unit as of the acquisition date.  

Auditing  management’s  annual  goodwill  impairment  test  was  complex  and  highly  judgmental  due  to  the 
significant estimation required in determining the fair value of the reporting unit.  In particular, the fair value 
estimate of the Contract Drilling Services reporting unit was sensitive to significant assumptions such as the 
weighted average cost of capital, forecasted day rates and utilization, operating margin, working capital and 
terminal value, which are affected by expectations about future market or economic conditions. 

Our audit 
response 

Our audit procedures related to the key audit matter of valuation of goodwill of the contract drilling services 
reporting unit included the following procedures:  

We obtained an understanding, evaluated the design and tested the operating effectiveness of the Company’s 
controls over its goodwill impairment assessment process. 

To test the estimated fair value of the Company’s Contract Drilling Services reporting unit, we performed audit 
procedures  that  included,  among  others,  assessing  methodologies  and  testing  the  significant  assumptions 
discussed above and the underlying data used by the Company in its analysis.  We compared the significant 
assumptions  used  by  management  to  current  industry  and  economic  trends,  including  offshore  activity, 
changes to the Company’s business model, customer analysis and other relevant factors.  We assessed the 
historical accuracy of management’s estimates and performed sensitivity analyses of significant assumptions 
to evaluate the changes in the fair value of the Contract Drilling Services reporting unit that would result from 
changes in the assumptions.  In addition, we tested the reconciliation of the fair value of all reporting units to 
the market capitalization of the Company.

Realizability of deferred tax assets 

Area of 
emphasis  

As  discussed  in  Note 10  to  the  consolidated  financial  statements,  the  Company  had  deferred  tax  assets  of 
USD 87 million (net of a USD 681 million valuation allowance).  Valuation allowances for deferred tax assets 
are recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not 
be realized.  In evaluating the realizability of deferred tax assets, all available positive and negative evidence 
is  considered,  including  projected  future  taxable  income  and  the  existence  of  cumulative  losses  in  recent 
years. 

Auditing the realizability of deferred tax assets is complex because of the judgement involved in determining 
the sources of income available to realize the deferred tax assets, including projected future taxable income, 
tax  planning  strategies,  available  carrybacks,  and  utilization  of  deferred  tax  liabilities  and  uncertain  tax 
positions. 

Our audit 
response 

Our  audit  procedures  related  to  the  key  audit  matter  of  realizability  of  deferred  tax  assets  included  the 
following procedures: 

We evaluated the Company’s assessment of the realizability of deferred tax assets and the resultant valuation 
allowance.  We tested controls that address the risks of material misstatement relating to the realizability of 
deferred  tax  assets,  including  controls  over  management’s  projections  of  future  taxable  income,  the  future 
reversal  of  existing  taxable  temporary  differences  and  management’s  identification  and  use  of  available  tax 
planning strategies. 

Our audit procedures included, among others, testing forecasted taxable income and evaluating the availability 
of  future  taxable  temporary  differences.    We  evaluated  the  assumptions  used  by  the  Company  to  develop 
projections  of  future  taxable  income  and  temporary  differences  by  jurisdiction  and  tested  the  completeness 
and  accuracy  of  the  underlying  data  used  in  its  projections.    For  example,  we  compared  the  projections  of 
future taxable income with firm contractual agreements.  We also reconciled the projections of future taxable 
income with other forecasted financial information prepared by the Company. 

In addition, we involved our tax professionals to evaluate the application of tax law in the Company’s available 
tax planning strategies and projections of future taxable income. We also tested the Company’s scheduling of 
the reversal of existing temporary taxable differences.

TRANSOCEAN LTD. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 1—Business 

Overview—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.    We 
specialize  in  technically  demanding  sectors  of  the  offshore  drilling  business  with  a  particular  focus  on  ultra-deepwater  and  harsh 
environment drilling services.  Our mobile offshore drilling fleet is considered one of the most versatile fleets in the world.  We contract our 
drilling rigs, related equipment and work crews predominantly on a dayrate basis to drill oil and gas wells.  As of December 31, 2018, we 
owned or had partial ownership interests in and operated a fleet of 50 mobile offshore drilling units, including 32 ultra-deepwater floaters, 
14 harsh  environment  floaters  and  four  midwater  floaters.    As  of  December 31,  2018,  we  were  constructing  (i) four additional 
ultra-deepwater drillships and (ii) one additional harsh environment semisubmersible, in which we hold a partial ownership interest. 

Business  combinations—On  January 30,  2018,  we  acquired  an  approximate  97.7 percent  ownership  interest  in  Songa 
Offshore SE,  a  European  public  company  limited  by  shares,  or  societas  Europaea,  existing  under  the  laws  of  Cyprus  (“Songa”).    On 
March 28, 2018, we acquired the remaining shares not owned by us through a compulsory acquisition under Cyprus law, and as a result, 
Songa became our wholly owned subsidiary.  To complete these transactions, we issued 68.0 million shares and $863 million aggregate 
principal amount of 0.50% exchangeable senior bonds due January 30, 2023 (the “Exchangeable Bonds”).  As a result of the acquisition, 
we  acquired  seven mobile  offshore  drilling  units,  including  five harsh  environment  floaters  and  two midwater  floaters.    See  Note 4—
Business Combinations and Note 14—Equity. 

On  December 5,  2018,  we  acquired  Ocean Rig  UDW Inc.,  a  Cayman  Islands  exempted  company  with  limited  liability 
(“Ocean Rig”), in a merger transaction, and as a result, Ocean Rig became our wholly owned subsidiary.  To complete the acquisition, we 
issued 147.7 million shares and made an aggregate cash payment of $1.2 billion.  As a result of the acquisition, we acquired (i) 11 mobile 
offshore  drilling  units,  including  nine ultra-deepwater  floaters  and  two harsh  environment  floaters  and  (ii) the  contracts  relating  to  the 
construction of two ultra-deepwater drillships.  See Note 4—Business Combinations, Note 14—Equity and Note 22—Subsequent Events. 

Investment in unconsolidated affiliates—In the year ended December 31, 2018, we made an aggregate cash investment of 
$107 million  in  unconsolidated  affiliates,  including  an  initial  investment  of  $91 million,  representing  a  33.0 percent  interest,  in  Orion 
Holdings  (Cayman) Limited  (“Orion”),  a  Cayman  Islands  company  formed  to  construct  and  own  the  newbuild  harsh  environment 
semisubmersible Transocean Norge.  We account for this investment, recorded in other assets, using the equity method of accounting.  
The total purchase price for the rig, under construction at the Jurong Shipyard Pte Ltd. in Singapore, is $500 million.  We have agreed to 
make  additional  contributions  of  $59 million  and  $33 million  to  Orion  in  January 2019  and  January 2020,  respectively.    We  expect  to 
operate  the  rig,  through  one of  our  wholly  owned  subsidiaries,  under  a  drilling  contract  that  is  expected  to  commence  in  July 2019.  
Additionally, we invested $16 million in other companies, recorded in other assets using the cost method of accounting, that are involved in 
researching and developing technology to improve automation in drilling and other activities. 

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 are required to make 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 allowance for doubtful accounts, materials and supplies obsolescence, property and equipment, assets held 
for sale, goodwill, income taxes, contingencies, share-based compensation and postemployment benefit plans.  We base our estimates 
and assumptions on historical experience and on various other factors 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 could differ from such estimates. 

Fair value measurements—We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability 
in  an  orderly  transaction  between  market  participants  in  the  principal  market  for the  asset  or  liability.    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 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 apply the cost method of accounting for an 
investment in an entity if we do not have the ability to exercise significant influence over the unconsolidated entity.  We separately present

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

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 14—Equity. 

Business combinations—In connection with our acquisitions, we applied the acquisition method of accounting.  Accordingly, 
we recorded the acquired assets and assumed liabilities at fair value and recognized goodwill to the extent the consideration transferred 
exceeded the fair value of the net assets acquired.  To the extent the fair value of the net assets acquired exceeded the consideration 
transferred, we recognize a bargain purchase gain, recorded in other income, net.  We estimated the fair values of the acquired assets and 
assumed liabilities as of the date of the acquisition, and our estimates are subject to adjustment based on our ongoing assessments of the 
fair values of property and equipment, intangible assets, other assets and liabilities and our evaluation of tax positions and contingencies, 
which are ongoing.  We will complete our final assessments of the fair values of the acquired assets and assumed liabilities and our final 
evaluations of uncertain tax positions and contingencies within one year of the acquisition date.  See Note 4—Business Combinations. 

Goodwill—We conduct impairment testing for our goodwill annually as of October 1 and more frequently, on an interim basis, 
when an event occurs or circumstances change that indicate that the fair value of our reporting unit may have declined below its carrying 
value.  We test goodwill at the reporting unit level, which is defined as an operating segment or one level below an operating segment that 
constitutes a business for which financial information is available and is regularly reviewed by management.  We determined that we have 
a single reporting unit for this purpose.  Before testing goodwill, we consider whether or not to first assess qualitative factors to determine 
whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting 
unit is less than its carrying amount.  If, as the result of our qualitative assessment, we determine that an impairment test is required, or, 
alternatively, if we elect to forgo the qualitative assessment, we record an impairment to goodwill to the extent the carrying amount of the 
reporting  unit,  including  goodwill,  exceeds  the  fair  value  of  the  reporting  unit.    In the  year ended December 31,  2018,  as  a  result  of  an 
interim  goodwill  test,  we  recognized  an  aggregate  loss  of  $462 million,  which  had  no  tax  effect,  associated  with  the  impairment  of  our 
goodwill.  See Note 3—Accounting Standards Updates, Note 4—Business Combinations and Note 7—Goodwill and Other Intangibles. 

Contract  intangibles—In  connection  with  our  acquisitions,  we  recognized  drilling  contract  intangible  assets  related  to  the 
acquired drilling contracts for future contract drilling services and construction contract intangible liabilities related to the acquired shipyard 
contracts for the construction of two rigs.  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 recognize the amortization on a straight-line basis over the expected remaining 
contract period as a reduction of contract drilling revenues.  The construction contract intangible liabilities resulting from the Ocean Rig 
acquisition represent the amount by which the remaining amounts due under the acquired contracts were above market construction rates 
for  similar  drilling  units,  measured  as  of  the  acquisition  date.    We  expect  to  recognize  the  construction  contract  intangible  liabilities  as 
reductions to the capitalized cost of the two rigs at the time we take delivery of the assets.  At December 31, 2018, the aggregate carrying 
amount  of  our  drilling  contract  intangible  assets  and  our  construction  contract  intangible  liabilities  was  $795 million  and  $132 million, 
respectively.    See  Note 4—Business  Combinations,  Note 7—Goodwill  and  Other  Intangibles  and  Note 13—Commitments  and 
Contingencies. 

Derivative instruments—We record derivatives on our consolidated balance sheet, measured at fair value.  We recognize the 
gains and losses associated with changes in the fair value of undesignated derivatives in current period earnings.  See Note 9—Derivative 
Instruments. 

Revenue  recognition—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  full  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, which we recognize on a straight-line basis over the estimated firm contract period.  We recognize losses for 
loss  contracts  as  such  losses  are  incurred.    We  recognize  revenues  for  demobilization  or  from  contract  terminations  as  we  fulfill  our 
obligations and all contingencies have been resolved.  To obtain contracts with our customers, we incur costs to prepare a rig for contract 
and deliver or mobilize a rig to the drilling location.  We defer pre-operating costs, such as contract preparation and mobilization costs, and 
recognize such  costs on a straight-line basis, consistent with the general pace of activity, in operating and maintenance costs  over the 
estimated firm period of drilling. 

We elected to 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  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.  See Note 5—Revenues.

the 

Share-based  compensation—To  measure 

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 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 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.    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.  In the years ended December 31, 2018, 2017 and 2016, 
share-based compensation expense was $45 million, $41 million and $42 million, respectively.  See Note 15—Share Based Compensation 
Plans. 

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, 2018, 
2017  and  2016,  we  capitalized  interest  costs  of  $37 million,  $116 million  and  $176 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, 2018, 2017 and 2016, we recognized 
a net loss of $38 million, a net loss of $6 million and a net loss of $2 million, respectively, related to currency exchange rates. 

Income taxes—We provide for income taxes based on the tax laws and rates in effect in the countries in which we operate and 
earn  income.    We  recognize  the  effect  of  changes  in  tax  laws  as  of  the  date  of  enactment.    Effective  January 1,  2018,  we  recognize 
potential global intangible low-taxed income inclusions as a period cost.  There is little or no expected relationship between the provision 
for or benefit from income taxes and income or loss before income taxes because the countries in which we operate have taxation regimes 
that vary not only with respect to nominal rate, but also in terms of the availability of deductions, credits and other benefits.  Variations also 
arise because income earned and taxed in any particular country or countries may fluctuate from year to year. 

We  measure  deferred  tax  assets  and  liabilities  using  enacted  tax  rates  that  will  apply  in  the  years  in  which  the  temporary 
differences are expected to be recovered or paid.  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.  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 also record a valuation allowance for deferred tax assets resulting from net operating losses incurred during the year in 
certain jurisdictions and for other deferred tax assets where, in our opinion, it is more likely than not that the financial statement benefit of 
these losses will not be realized.  Additionally, we record a valuation allowance for foreign tax credit carryforwards to reflect the possible 
expiration of these benefits prior to their utilization. 

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.  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.  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. 

Short-term  investments—We  periodically  deposit  unrestricted  excess  funds  in  time  deposits  and  commercial  paper  with 

original maturities beyond three months.  Such short-term investments are with commercial banks with high credit ratings. 

Accounts  receivable—We  earn  our  revenues  by  providing  our  drilling  services  to  international  oil  companies  and 
government-owned or government-controlled oil companies.  We evaluate the credit quality of our customers on an ongoing basis, and we 
may occasionally require collateral or other security to support customer receivables.  We establish an allowance for doubtful accounts on 
a  case-by-case  basis,  considering  changes  in  the  financial  position  of  a  customer,  when  we  believe  the  required  payment  of  specific 
amounts owed to us is unlikely to occur.  At December 31, 2018 and 2017, the allowance for doubtful accounts was less than $1 million. 

Materials  and  supplies—We  record  materials  and  supplies  at  their  average  cost  less  an  allowance  for  obsolescence.    We 
estimate the allowance for obsolescence based on historical experience and expectations for future use of the materials and supplies.  At 
December 31, 2018 and 2017, the allowance for obsolescence was $134 million and $141 million, respectively. 

AR-59 

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

Restricted cash accounts and investments—We maintain restricted cash accounts and investments 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 accounts and investments 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.  At December 31, 2018, the aggregate carrying amount of our restricted cash accounts and investments was 
$552 million, of which $551 million and $1 million was classified in current assets and other assets, respectively.  At December 31, 2017, 
the aggregate carrying amount of our restricted cash accounts and investments was $489 million, of which $466 million and $23 million 
was  classified  in  current  assets  and  other  assets,  respectively.    See  Note 3—Accounting  Standards  Updates,  Note 8—Debt,  Note 13—
Commitments and Contingencies and Note 18—Financial Instruments. 

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, 2018 and 2017, the aggregate carrying amount of our assets held for sale, recorded 
in other current assets, was $25 million and $22 million, respectively.  See Note 6—Drilling Fleet. 

Property and equipment—The carrying amounts of our property and equipment, consisting primarily of offshore drilling rigs and 
related equipment, are based on our estimates, assumptions and judgments relative to capitalized costs, useful lives and salvage values of 
our  rigs.    These  estimates,  assumptions  and  judgments  reflect  both  historical  experience  and  expectations  regarding  future  industry 
conditions  and  operations.    At  December 31,  2018,  the  aggregate  carrying  amount  of  our  property  and  equipment  represented 
approximately 80 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 lives of our drilling units range from 30 to 35 years, our buildings and improvements range from 
two 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,  principally  property  and  equipment,  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,  harsh  environment  floaters  and  midwater  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 contract drilling asset groups by applying a variety of valuation methods, incorporating a combination of cost, income and 
market 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—Drilling Fleet. 

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 our 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  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. 

AR-60 

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

At  December 31,  2018  and  2017,  our  pension  and  other  postemployment  benefit  plan  obligations  represented  an  aggregate 
liability of $362 million and $359 million, respectively, and an aggregate asset of $47 million and $17 million, respectively, representing the 
funded status of the plans.  In the years ended December 31, 2018, 2017 and 2016, aggregate net periodic benefit costs were income of 
$9 million,  costs  of  $5 million  and  income  of  $11 million,  respectively.    See  Note 3—Accounting  Standards  Updates  and  Note 12—
Postemployment Benefit Plans. 

Contingencies—We  perform  assessments  of  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.    We  recognize  corresponding  assets  for  those  loss 
contingencies that we believe are probable of being recovered through insurance.  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  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. 

Reclassifications—We  have  made  certain  reclassifications  to  prior  period  amounts  to  conform  with  the  current  year’s 
presentation.    In  our  consolidated  balance  sheet  as  of  December 31,  2017,  we  reclassified  certain  balances  receivable  from 
non-customers, totaling $45 million, from accounts receivable, net, to other current assets.  Such reclassifications did not have a material 
effect on our consolidated statement of financial position, results of operations or cash flows. 

Note 3—Accounting Standards Updates 

Recently adopted accounting standards 

Revenue  from  contracts  with  customers—Effective  January 1,  2018,  we  adopted  the  accounting  standards  update  that 
requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that 
reflects  the  consideration  to  which  the  entity  expects  to  be  entitled  in  exchange  for  those  goods  or  services.    In  our  evaluation  of  the 
requirements, we determined that reimbursement revenues and contract early cancellation and termination fees were part of our single 
performance  obligation,  and  we  determined  that  reimbursement  revenues  should  be  recorded  on  a  gross  basis  as  the  service  is 
performed.  Our adoption, using the modified retrospective approach, for which we were not required to make any changes to the prior 
year presentation, did not have a material effect on our consolidated statements of financial position, operations or cash flows. 

Income taxes—Effective January 1, 2018, we adopted the accounting standards update that requires an entity to recognize the 
income tax consequences of an intra entity transfer of an asset other than inventory when the transaction occurs as opposed to deferring 
such  recognition  into  future  periods.    Our  adoption  did  not  have  a  material  effect  on  our  consolidated  statements  of  financial  position, 
operations or cash flows or on the disclosures contained in our notes to consolidated financial statements. 

Statement  of  cash  flows—Effective  January 1,  2018,  we  adopted  the  accounting  standards  update  that  requires  amounts 
generally described as restricted cash or restricted cash equivalents to be included with cash and cash equivalents when reconciling the 
beginning  and  end  of  period  total  amounts  presented  on  the  statement  of  cash  flows.    Aside  from  presenting  the  restricted  cash  and 
restricted cash equivalents as a component of the beginning and ending cash balances on our consolidated statements of cash flows, we 
removed the effect of proceeds from and deposits to restricted accounts from our cash flows provided by or used in operating, investing 
and financing activities, as applicable.  For the years ended December 31, 2018 and 2017, such changes did not have a material effect on 
our consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes to consolidated 
financial statements. 

Retirement  benefits—Effective  January 1,  2018,  we  adopted  the  accounting  standards  update  that  requires  an  employer  to 
disaggregate the service cost component from the other components of net benefit cost related to defined benefit retirement plans and 
other postemployment benefit plans.  The update requires that the service cost component be presented in the same line item as other 
compensation  costs  for  employees  and  the  other  components  of  net  benefit  cost  in  other  income  and  expense  on  our  consolidated 
statements of operations.  The update also allows only the service cost component of net benefit cost to be eligible for capitalization.  Our 
adoption did not have a material effect on our consolidated statements of financial position, operations or cash flows or on the disclosures 
contained in our notes to consolidated financial statements. 

Goodwill—Effective  January 1,  2018,  we  early  adopted  the  accounting  standards  update  that  simplifies  the  method  for 
measuring  the  implied  value  of  goodwill  when  performing  a  goodwill  impairment  test  by  performing  a  one-step  test,  comparing  the  fair 
value of the reporting unit with its carrying amount.  The update eliminates the two-step requirement to perform procedures to determine 
the fair value of assets and liabilities on the same basis as required in a business combination.  In the year ended December 31, 2018, we 
applied this simplified method in our interim goodwill test, and we recognized an aggregate loss of $462 million, which had no tax effect, 
associated with the full impairment of our goodwill.

Recently issued accounting standards 

Leases—Effective January 1, 2019, we will adopt the accounting standards update that (a) requires lessees to recognize a right 
to  use  asset  and  a  lease  liability  for  virtually  all  leases,  and  (b) updates  previous  accounting  standards  for  lessors  to  align  certain 
requirements  with  the  updates  to  lessee  accounting  standards  and  the  revenue  recognition  accounting  standards.    In  a  recent  update, 
targeted improvements were made that provide for (a) an optional new transition method for adoption that results in initial recognition of a 
cumulative  effect  adjustment  to  retained  earnings  in  the  year  of  adoption  and  (b) a  practical  expedient  for  lessors,  under  certain 
circumstances,  to  combine  the  lease  and  non-lease  components  of  revenues  for  presentation  purposes.    We  expect  to  elect  the  new 
optional transition method of adoption.  With respect to our drilling contracts, which could contain a lease component, we expect to apply 
the  practical  expedient  and  recognize  revenues  based  on  the  service  component,  which  we  have  determined  is  the  predominant 
component of our contracts.  With respect to the lease arrangements under which we are the lessee as of December 31, 2018, we expect 
to recognize an aggregate lease liability of between $130 million and $140 million and a right-of-use asset of between $100 million and 
$110 million.  We do not expect our adoption to have a material effect on our consolidated statements of financial position, operations or 
cash flows. 

Other  comprehensive  income—Effective  January 1,  2019,  we  will  adopt  the  accounting  standards  update  that  allows  for 
reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts 
and Jobs Act (the “2017 Tax Act”).  We expect to apply the permitted alternative and reclassify such stranded tax effects resulting from the 
2017 Tax Act.  We do not expect our adoption to have a material effect on our consolidated statements of financial position, operations or 
cash flows or on the disclosures contained in our notes to consolidated financial statements. 

Financial instruments – credit losses—Effective no later than January 1, 2020, we will adopt the accounting standards update 
that requires entities to estimate an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to 
long-term  financings.    The  update,  which  permits  early  adoption,  is  effective  for  annual  reporting  periods  beginning  after  December 15, 
2019, including interim periods within those fiscal years.  We continue to evaluate the requirements and do not expect our adoption to have 
a material effect on our consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes 
to consolidated financial statements. 

Note 4—Business Combinations 
Overview 

During the year ended December 31, 2018, we completed the acquisitions of Songa and Ocean Rig.  On January 30, 2018, we 
acquired an approximate 97.7 percent ownership interest in Songa.  We believe the Songa acquisition strengthens our position as a leader 
in harsh environment and ultra-deepwater drilling services by adding high value assets, including four high-specification harsh environment 
floaters,  supported  by  significant  contract  backlog,  and  strengthens  our  footprint  in  harsh  environment  operating  areas.    The  goodwill 
resulting from the business combination was attributed to synergies and intangible assets that did not qualify for separate recognition.  On 
December 5, 2018, we acquired Ocean Rig in a merger transaction.  We believe the Ocean Rig acquisition further strengthens our position 
as  a  leader  in  the  ultra-deepwater  and  harsh  environment  drilling  services  by  adding  additional  high-value  assets,  including 
nine ultra-deepwater  floaters  and  two harsh  environment  floaters,  and  the  contracts  relating  to  the  construction  of  two ultra-deepwater 
drillships (see Note 22—Subsequent Events).  In the year ended December 31, 2018 and 2017, in connection with these acquisitions, we 
incurred acquisition costs of $24 million and $4 million, respectively, recorded in general and administrative costs and expenses. 

Pro forma combined operating results—We have included the operating results of Songa and Ocean Rig in our consolidated 
results  of  operations,  commencing  on  the  acquisition  date,  January 30,  2018  and  December 5,  2018,  respectively.    In  the  year ended 
December 31, 2018, our consolidated statement of operations includes revenues of $497 million and net income of $87 million associated 
with  the  operations  of  Songa  and  revenues  of  $15 million  and  net  loss  of  $8 million  associated  with  the  operations  of  Ocean Rig.    Pro 
forma combined operating results, assuming the acquisitions were completed as of January 1, 2017, were as follows (in millions, except 
per share data):

As a result of the acquisition, we recognized a gain of $10 million, recorded in other, net, associated with the bargain purchase, 
primarily due to the decline in the market value of our shares between the announcement date and the closing date.  We estimated the fair 
value of the rigs and related equipment by applying a combination of income and market 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 markets for the 
assets in an orderly transaction between participants as of the acquisition date.  We estimated the fair value of the drilling contracts by 
comparing the contractual dayrates over the remaining firm contract term and option periods relative to the projected market dayrates as of 
the acquisition date.  We estimated the fair value of the construction contracts by comparing the contractual future payments and terms 
relative  to  the  market  payments  and  terms  as  of  the  acquisition  date.    Our  estimates  of  fair  value  for  the  drilling  units  and  contract 
intangibles required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions 
related to the future performance of the assets, such as future commodity prices, projected demand for our services, rig availability, rig 
utilization, dayrates, remaining useful lives of the rigs and discount rates. 

We have not completed our estimates of the fair values of assets acquired and liabilities assumed.  We continue to review the 
estimated  fair  values  of  property  and  equipment,  intangible  assets,  and  other  assets  and  liabilities,  and  to  evaluate  the  assumed  tax 
positions and contingencies.  Our estimates of the fair value for such assets and liabilities require significant assumptions and judgment.  
Until we complete our evaluation, we may be required to adjust our original estimates, and such adjustments could be material. 

Songa Offshore SE 

Consideration—To complete the acquisition, we issued 66.9 million shares with a per share market value of $10.99, based on 
the market value of our shares on the acquisition date.  We also issued $854 million aggregate principal amount of Exchangeable Bonds, 
including  $562 million  aggregate  principal  amount  as  partial  consideration  to  Songa  shareholders  and  $292 million  aggregate  principal 
amount  as  settlement  for  certain  Songa  indebtedness.    The  aggregate  fair  value  of  the  consideration  transferred  in  the  business 
combination was as follows (in millions):

In the year ended December 31, 2018, we completed our estimates of the fair values of the assets and liabilities.  We estimated 
the fair value of the rigs and related equipment by applying a combination of income and market 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 markets for the 
assets in an orderly transaction between participants as of the acquisition date.  We estimated the fair value of the drilling contracts by 
comparing the contractual dayrates over the remaining firm contract term and option periods relative to the projected market dayrates as of 
the acquisition date.  Our estimates of fair value for these assets required us to use significant unobservable inputs, representative of a 
Level 3 fair value measurement, including assumptions related to the future performance of the assets, such as future commodity prices, 
projected demand for our services, rig availability, dayrates and discount rates.  We estimated the fair value of the debt using significant 
other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. 

Noncontrolling interest—On March 28, 2018, we acquired the remaining Songa shares not owned by us through a compulsory 
acquisition under Cyprus law, and as a result, Songa became our wholly owned subsidiary.  As consideration  for the remaining Songa 
shares, we issued 1.1 million shares and $9 million aggregate principal amount of Exchangeable Bonds and we made an aggregate cash 
payment of $8 million to Songa shareholders who elected to receive a cash payment or failed to make an election, for an aggregate fair 
value of $30 million. 

Note 5—Revenues 

Overview—The services we perform represent a single performance obligation under our drilling contracts with customers that is 
satisfied  over  time.    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. 

The duration of our performance obligation varies by contract.  At December 31, 2018, the expected remaining duration of our 
drilling contracts extends through February 2028, excluding unexercised options.  In the year ended December 31, 2018, we recognized 
revenues  of  $174 million,  respectively,  for  performance  obligations  satisfied  in  previous  periods,  primarily  related  to  our  customer’s 
termination of the contract for Discoverer Clear Leader, effective November 2017, and certain revenues recognized on a cash basis. 

In  the  years  ended  December 31,  2018,  2017  and  2016,  we  recognized  costs  of  $45 million,  $45 million  and  $86 million, 
respectively,  associated  with  pre-operating  costs  for  contracts  with  customers.    At  December 31,  2018  and  2017,  the  unrecognized 
pre-operating costs to obtain contracts was $2 million and $18 million, respectively, recorded in other assets. 

Disaggregation—In the years ended December 31, 2018, 2017 and 2016, we recognized revenues as follows (in millions): 

Ultra-deepwater floaters 
Harsh environment floaters
Deepwater floaters 
Midwater floaters

included  a  significant  decline  in  commodity  prices  and  the  market  value  of  our  stock,  a  reduction  of  projected  dayrates  and  a  further 
extension of low utilization rates, and in the year ended December 31, 2016, such indicators included a reduction of projected dayrates and 
an extension to low utilization rates.  In the year ended December 31, 2017, as a result of our testing, we recognized a loss of $94 million 
($93 million, or $0.25 per diluted share, net of tax) associated with the impairment of the midwater floater asset group.  In the year ended 
December 31,  2016,  as  a  result  of  our  testing,  we  recognized  a  loss  of  $52 million  ($0.14 per  diluted  share),  which  had  no  tax  effect, 
associated with the impairment of the deepwater floater asset group. 

We measured the fair value of the asset groups by applying a combination of income and market 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 
markets for the assets in an orderly transaction between participants as of the measurement date.  Our estimate of fair value required us to 
use  significant  unobservable  inputs,  representative  of  a  Level 3  fair  value  measurement,  including  assumptions  related  to  the  future 
performance  of  our  contract  drilling  services  reporting  unit,  such  as  future  commodity  prices,  projected  demand  for  our  services,  rig 
availability  and  dayrates.    If  we  experience  increasingly  unfavorable  changes  to  actual  or  anticipated  dayrates  or  other  impairment 
indicators, or if we are unable to secure new or extended contracts for our active units or the reactivation of any of our stacked units, we 
may be required to recognize additional losses in future periods as a result of impairments of the carrying amount of one or more of our 
asset groups. 

Impairments of assets held for sale—In the year ended December 31, 2018, we recognized an aggregate loss of $999 million 
($2.13 per diluted share), which had no tax effect, associated with the impairment of the ultra-deepwater floaters  Deepwater Discovery, 
Deepwater Frontier, Deepwater Millennium and GSF C.R. Luigs, the deepwater floaters Jack Bates and Transocean 706 and the midwater 
floaters Songa Delta and Songa Trym, along with related assets, which we determined were impaired at the time that we classified the 
assets as assets held for sale. 

In the year ended December 31, 2017, we recognized an aggregate loss of $1.4 billion ($3.59 per diluted share), which had no 
tax  effect,  associated  with  the  impairment  of  the  ultra-deepwater  floaters  Cajun Express,  Deepwater Pathfinder,  GSF Jack Ryan, 
Sedco Energy  and  Sedco Express,  the  deepwater  floater  Transocean Marianas  and  the  midwater  floaters  Transocean Prospect  and 
Transocean Searcher, along with related assets, which we determined were impaired at the time that we classified the assets as assets 
held for sale. 

In the year ended December 31, 2016, we recognized an aggregate loss of $41 million ($39 million, or $0.10 per diluted share, 
net  of  tax)  associated  with  the  impairment  of  the  deepwater  floaters  M.G. Hulme, Jr.  and  Sedco 702  and  the  midwater  floaters 
GSF Rig 140,  Sedco 704,  Transocean Driller,  Transocean John Shaw  and  Transocean Winner,  along  with  related  assets,  which  we 
determined were impaired at the time that we classified the assets as assets 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, 2018, in connection with our efforts to dispose of non-strategic assets, we 
completed  the  sale  of  the  ultra-deepwater  floaters  Cajun Express,  Deepwater Discovery,  Deepwater Pathfinder,  GSF C.R. Luigs, 
Sedco Energy and Sedco Express, the deepwater floater Transocean Marianas and the midwater floater Songa Trym, along with related 
assets.  In the year ended December 31, 2018, we received aggregate net cash proceeds of $36 million and recognized an aggregate net 
gain  of  $7 million  ($0.01 per  diluted  share),  which  had  no  tax  effect,  associated  with  the  disposal  of  these  assets.    In  the  year ended 
December 31, 2018, we received aggregate net cash proceeds of $7 million and recognized an aggregate net loss of $7 million associated 
with the disposal of assets unrelated to rig sales.

($4.08 per diluted share), which had no tax effect, associated with the disposal of these assets.  Following the completion of the sale, we 
continued to operate three of these high-specification jackups through completion of the drilling contracts, the last of which was completed 
in  October 2018.    In  the  years  ended  December 31,  2018,  2017  and  2016,  excluding  our  loss  on  the  disposal  of  these  assets,  our

ultra-deepwater floaters Deepwater Frontier and Deepwater Millennium, the deepwater floaters Jack Bates and Transocean 706 and the 
midwater floater Songa Delta, along with related assets, was $25 million, recorded in other current assets.  At  December 31, 2017, the 
aggregate  carrying  amount  of  our  assets  held  for  sale  was  $22 million,  including  the  ultra-deepwater  floaters  Cajun Express, 
Deepwater Pathfinder,  Sedco Energy  and  Sedco Express  and  the  deepwater  floater  Transocean Marianas,  along  with  related  assets, 
recorded in other current assets. 

Note 7—Goodwill and Other Intangibles 

Goodwill—During  the  three months  ended  June  30,  2018,  we  classified  as  held  for  sale  and  impaired  three ultra-deepwater 
floaters (see Note 6—Drilling Fleet).  We identified the impairment of these assets included in our single contract drilling services reporting 
unit as a trigger to test the recoverability of goodwill.  As a result, we performed an interim goodwill impairment test as of June 30, 2018, 
and  we  determined  that  the  goodwill  associated  with  our  contract  drilling  services  reporting  unit  was  fully  impaired.    In  the  year ended 
December 31,  2018,  we  recognized  a  loss  of  $462 million  ($0.99 per  diluted  share),  which  had  no  tax  effect,  associated  with  the 
impairment of the full balance of our goodwill.  We estimated the fair value of the contract drilling services reporting unit using the income 
approach.    Our  estimate  of  fair  value  required  us  to  use  significant  unobservable  inputs,  representative  of  a  Level 3  fair  value 
measurement, including assumptions related to the future performance of the reporting unit, such as future commodity prices, projected 
demand for our services, rig availability and dayrates. 

Finite-lived intangible assets and liabilities—At December 31, 2018, the gross carrying amount and accumulated amortization 

of our drilling contract intangible assets were as follows (in millions):

In  the  year ended  December 31,  2018,  we  recognized  drilling  contract  intangible  amortization  of  $112 million  recorded  as  a 
reduction  of  contract  drilling  revenues.    We  expect  to  amortize  the  carrying  amounts  over  the  remaining  contract  periods,  through 
March 2024.  As of December 31, 2018, the estimated future amortization of contract intangible assets was as follows (in millions):

the assets.

(a)  Transocean Inc.,  a  100  percent  owned  direct  subsidiary  of  Transocean Ltd.,  is  the  issuer  of  the  notes  and  debentures.    Transocean Ltd.  has 
provided a full and unconditional guarantee of the notes and debentures.  Transocean Ltd. has no independent assets or operations, and its other 
subsidiaries not owned indirectly through Transocean Inc. were 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.  Except 
as discussed under “Indentures,” 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. 

(b)  The subsidiary issuer of the unregistered senior secured notes is a wholly owned indirect subsidiary of Transocean Inc.  The senior secured notes 

are fully and unconditionally guaranteed by the owner of the collateral rig.  See “—Debt issuances—Senior secured notes.” 

(c)  Transocean Inc. is the issuer of the unregistered notes.  The priority guaranteed senior unsecured notes, which rank equal in right of payment of all 
of  our  existing  and  future  unsecured  unsubordinated  obligations  and  rank  structurally  senior  to  the  extent  of  the  value  of  the  assets  of  the 
subsidiaries guaranteeing the notes, are fully and unconditionally, jointly and severally, guaranteed by Transocean Ltd. and certain wholly owned 
subsidiaries of Transocean Inc.  See “—Debt issuances—Priority guaranteed senior unsecured notes.”

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.   

Additionally,  the  indentures  that  govern  the  5.875% senior  secured  notes  due  January 2024  (the  “5.875% Senior  Secured 
Notes”),  the  6.125% senior  secured  notes  due  August 2025  (the  “6.125% Senior  Secured  Notes”),  the  5.52% senior  secured  notes  due 
May 2022  (the  “5.52% Senior  Secured  Notes”),  the  7.75% senior  secured  notes  due  October 2024  (the  “7.75% Senior  Secured  Notes”) 
and the 6.25% senior secured notes due December 2024 (the “6.25% Senior Secured Notes”) 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 5.875% Senior Secured Notes, the 
6.125% Senior Secured Notes, the 7.75% Senior Secured Notes and the 6.25% Senior Secured Notes also impose a maximum collateral 
rig  leverage  ratio  (“Maximum  Collateral  Ratio”),  represented  by  the  debt  balance  relative  to  each  rig’s  earnings,  that  changes  over  the 
terms of the notes.  At December 31, 2018, the Maximum Collateral Ratio under the respective indenture was as follows: (i) 6.00 to 1.00 
for  the  5.875% Senior  Secured  Notes,  (ii) 5.75 to 1.00  for  the  6.125% Senior  Secured  Notes  and  (iii) 4.75 to  1.00  for  the  7.75% Senior 
Secured Notes and the 6.25% Senior Secured Notes. 

Interest rate adjustments—The interest rates for certain of our 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 (“Debt Rating”).  At December 31, 2018, the interest rate in 
effect for the 6.375% senior notes due December 2021 (the”6.375% Senior Notes”), the 3.80% senior notes due October 2022 (the”3.80% 
Senior Notes”) and the 7.35% senior notes due December 2041 was 8.375 percent, 5.80 percent and 9.35 percent, respectively. 

Secured  Credit  Facility—In  June 2018,  we  entered  into  a  bank  credit  agreement,  which  established  a  $1.0 billion  secured 
revolving credit facility (the “Secured Credit Facility”), which is scheduled to expire on the earlier of (i) June 22, 2023 and (ii) if greater than 
$300 million  aggregate  principal  amount  of  our  9.00% senior  notes  due  July 2023  (the”9.00%  Senior  Notes”)  remain  outstanding  in 
April 2023, such date.  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 Invictus  and 
Discoverer Inspiration  and  the  harsh  environment  floaters  Transocean Barents  and  Transocean Spitsbergen,  the  aggregate  carrying 
amount of which was $3.4 billion at December 31, 2018.  The Secured Credit Facility contains covenants that, among other things, include 
maintenance  of  certain  guarantee  and  collateral  coverage  ratios,  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. 

We may borrow under the Secured Credit Facility at either (1) the reserve adjusted London interbank offered rate plus a margin 
(the “Secured Credit Facility Margin”), which ranges from 2.625 percent to 3.375 percent based on the credit rating of the Secured Credit 
Facility,  or  (2) the  base  rate  specified  in  the  credit  agreement  plus  the  Secured  Credit  Facility  Margin,  minus  one percent  per  annum.  
Throughout the term of the Secured Credit Facility, we pay a facility fee on the amount of the underlying commitment which ranges from 
0.375 percent to 1.00 percent based on the credit rating of the Secured Credit Facility.  At December 31, 2018, based on the credit rating 
of the Secured Credit Facility on that date, the Secured Credit Facility Margin was 2.75 percent and the facility fee was 0.50 percent.  At 
December 31,  2018,  we  had  no borrowings  outstanding,  $25 million  of  letters  of  credit  issued,  and  we  had  $1.0 billion  of  available 
borrowing capacity under the Secured Credit Facility.  See Note 13—Commitments and Contingencies—Global Marine litigation.

100 percent of the aggregate principal amount plus a make-whole provision, and on or after November 1, 2021, at specified redemption 
prices. 

On  October 17,  2017,  we  completed  an  offering  of  an  aggregate  principal  amount  of  $750 million  of  7.50% senior  unsecured 
notes due January 15, 2026 (the “7.50% Senior Notes”), and we received aggregate cash proceeds of $742 million, net of issue costs.  We

aggregate principal amount plus a make-whole provision, and on or after January 15, 2021, at specified redemption prices. 

On July 21, 2016, we completed an offering of an aggregate principal amount of $1.3 billion of the 9.00% Senior Notes and we 
received aggregate cash proceeds of $1.2 billion, net of initial discount and costs payable by us.  We may redeem all or a portion of the 
9.00% Senior Notes at any time prior to July 15, 2020 at a price equal to 100 percent of the aggregate principal amount plus a make-whole

Senior secured notes—In July 2018, we issued $750 million aggregate principal amount of 5.875% Senior Secured Notes and 
$600 million aggregate principal amount of 6.125% Senior Secured Notes, and we received aggregate cash proceeds of $733 million and 
$586 million, respectively, net of discount and issue costs.  The 5.875% Senior Secured Notes are secured by the assets and earnings 
associated  with  the  harsh  environment  floaters  Transocean Enabler  and  Transocean Encourage  and  the  equity  of  the  wholly  owned 
subsidiaries that own or operate the collateral rigs.  The 6.125% Senior Secured Notes are secured by the assets and earnings associated 
with the ultra-deepwater floater Deepwater Pontus and the equity of the wholly owned subsidiaries that own or operate the collateral rig.  In 
connection with the issuance of such notes, we were required to deposit $63 million, with respect to the 5.875% Senior Secured Notes, 
and  $51 million  with  respect  to  the  6.125% Senior  Secured  Notes,  in  restricted  cash  accounts  to  satisfy  debt  service  and  reserve 
requirements.  We are required to pay semiannual installments of principal and interest on the 5.875% Senior Secured Notes, beginning 
January 15, 2019, and on the 6.125% Senior Secured Notes, beginning February 1, 2019.  We may redeem all or a portion of these notes 
at a price equal to 100 percent of the aggregate principal amount plus a make-whole provision. 

On May 5, 2017, we issued $410 million aggregate principal amount of 5.52% Senior Secured Notes, and we received aggregate 
cash proceeds of $403 million, net of issue costs.  The 5.52% Senior Secured Notes are secured by the assets and earnings associated 
with the ultra-deepwater floater Deepwater Conqueror, the equity of the wholly owned subsidiaries that own and operate the collateral rig, 
and certain related assets.  We are required to pay quarterly installments of principal and interest on the 5.52% Senior Secured Notes.  We 
may  redeem  all  or  a  portion  of  the  5.52% Senior  Secured  Notes  at  any  time  on  or  prior  to  December 31,  2021  at  a  price  equal  to 
100 percent of the aggregate principal amount plus, subject to certain exceptions, a make-whole amount. 

On  October 19,  2016,  we  issued  $600 million  aggregate  principal  amount  of  7.75% Senior  Secured  Notes,  and  we  received 
aggregate cash proceeds of $583 million, net of initial discount and issue costs.  On December 8, 2016, we completed an offering of an 
aggregate principal amount of $625 million of 6.25% Senior Secured Notes, and we received aggregate cash proceeds of $609 million, net 
of initial discount and issue costs.  The 7.75% Senior Secured Notes and the 6.25% Senior Secured Notes are secured by the assets and 
earnings associated with the ultra-deepwater floater Deepwater Thalassa and the Deepwater Proteus, respectively, and the equity of the 
wholly  owned  subsidiary  that  owns  the  collateral  rig.    We  are  required  to  pay  semiannual  installments  of  principal  and  interest  on  the 
7.75% Senior Secured Notes and the 6.25% Senior Secured Notes.  We may redeem all or a portion of the 7.75% Senior Secured Notes 
and the 6.25% Senior Secured Notes at any time on or prior to October 15, 2020 and December 1, 2020, respectively, at a price equal to 
100 percent of the aggregate principal amount plus a make-whole provision. 

At December 31, 2018 and 2017, we had $347 million and $211 million, respectively, deposited in restricted cash accounts to 
satisfy debt service and working capital requirements for the senior secured notes.  At December 31, 2018, the aggregate carrying amount 
of Deepwater Conqueror, Deepwater Pontus, Deepwater Proteus, Deepwater Thalassa, Transocean Enabler and Transocean Encourage 
was  $4.4 billion.    At  December 31,  2017,  the  aggregate  carrying  amount  of  Deepwater Conqueror,  Deepwater Thalassa  and 
Deepwater Proteus was $2.4 billion.  We will be required to redeem the notes at a price equal to 100 percent of the aggregate principal 
amount  without  a  make-whole  provision,  upon  the  occurrence  of  certain  events  related  to  the  collateral  rigs  and  the  related  drilling 
contracts. 

Exchangeable  bonds—In  connection  with  the  Songa  acquisition  transactions,  we  issued  $863 million  aggregate  principal 
amount  of  Exchangeable  Bonds,  as  partial  consideration  for  the  Songa  shares  and  as  consideration  for  refinancing  certain  Songa 
indebtedness.  The Exchangeable Bonds may be converted at any time prior to the maturity date at an exchange rate of 97.29756 shares 
per  $1,000 note,  equivalent  to  a  conversion  price  of  $10.28 per  share,  subject  to  adjustment  upon  the  occurrence  of  certain  events.  
Holders of Exchangeable Bonds may require us to repurchase all or a portion of such holder’s Exchangeable Bonds upon the occurrence 
of  certain  events.    The  aggregate  fair  value  of  the  Exchangeable  Bonds,  measured  as  of  the  issuance  date,  was  $1.0 billion,  which 
represented a substantial premium of $172 million above par, and we recorded such premium to additional paid-in capital.  We estimated 
the fair value using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit 
spreads for the instruments.

Debt assumptions and repayments 

Senior Secured Term Loans and Junior Secured Bonds—In connection with the Songa acquisition, we assumed the rights 
and  obligations  under  credit  agreements  establishing  two senior  secured  term  loan  facilities  (the  “Senior  Secured  Term  Loans”)  and  a 
subscription agreement establishing a junior secured bond facility (the “Junior Secured Bonds”).  The credit agreements and subscription 
agreement  contained  change  of  control  clauses,  for  which  we  received  waivers  from  the  lenders  that  were  scheduled  to  expire  on 
August 31, 2018.  On February 12, 2018, we served notice of our intent to call the Junior Secured Bonds.  Prior to the expiration of the 
waivers, we made an aggregate cash payment of $1.4 billion and $171 million to repay the borrowings under the Senior Secured Term 
Loans and the Junior Secured Bonds, respectively, and terminated the underlying agreements.  We recognized an aggregate net loss of 
$1 million associated with the repaid borrowings. 

Other debt—In connection with the Songa acquisition, we assumed the indebtedness related to two bond loans (together, the 
“Bond  Loans”),  previously  publicly  traded  on  the  Oslo  stock  exchange.    On  the  acquisition  date,  the  Bond  Loans  had  an  aggregate 
principal  amount  of  NOK 337 million,  equivalent  to  $44 million.    On  March 14,  2018,  we  made  a  cash  payment  of  NOK 345 million, 
equivalent to $44 million, to repay the Bond Loans.  We also assumed the rights and obligations under a credit agreement for a secured 
borrowing facility.  On February 2, 2018, we made a cash payment of $23 million to repay the borrowings outstanding under the secured 
borrowing facility and terminated the underlying credit agreement. 

Debt retirements 

Repurchases  and  repayments—During  the  years  ended  December 31,  2018,  2017  and  2016,  we  repurchased  in  the  open

Note 9—Derivative Instruments 

Forward exchange contracts—At December 31, 2018, we held undesignated forward exchange contracts, extending through 
June 2019,  with  an  aggregate  notional  payment  amount  of  $76 million  and  an  aggregate  notional  receive  amount  of  NOK 600 million, 
representing  a  weighted  average  exchange  rate  of  NOK 7.94 to  $1.    In  the  year  ended  December 31,  2018,  we  recognized  a  loss  of 
$9 million,  recorded  in  other,  net,  associated  with  the  forward  exchange  contracts.    At  December 31,  2018,  the  undesignated  forward 
exchange contracts represented a liability with a carrying amount of $6 million, recorded in other current liabilities. 

In  connection  with  the  Songa  acquisition,  we  acquired  certain  undesignated  forward  exchange  contracts  for  the  purchase  of 
Norwegian kroner  that  extended  through  May 2018.    On  the  acquisition  date,  the  forward  exchange  contracts  represented  an  asset  of 
$4 million.    During  the  year ended  December 31,  2018,  we  settled  the  remaining  forward  exchange  contracts  upon  expiration.    In  the 
year ended  December 31,  2018,  we  recognized  a  loss  of  $1 million,  recorded  in  other,  net,  associated  with  the  forward  exchange 
contracts. 

Interest  rate  swaps—In  connection  with  the  Songa  acquisition,  we  acquired  interest  rate  swaps,  which  we  repaid  in  the 
year ended  December 31,  2018.    On  the  acquisition  date,  the  aggregate  fair  value  of  the  interest  rate  swaps  represented  an  asset  of 
$14 million.    In  July  and  August 2018,  we  received  aggregate  cash  proceeds  of  $18 million  in  connection  with  the  settlement  and 
termination of the interest rate swaps.  In the year ended December 31, 2018, we recognized a gain of $4 million, recorded in other, net, 
associated the interest rate swaps. 

Currency swaps—In connection with the Songa acquisition, we acquired currency swaps, which were previously designated as 
a cash flow hedge, to reduce the variability of cash interest payments and the final cash principal payment associated with the Bond Loans 
resulting from the changes in the U.S. dollar to Norwegian krone exchange rate.  On the acquisition date, the aggregate fair value of the 
currency swaps represented a liability of $81 million.  In February 2018, we made an aggregate cash payment of $92 million in connection 
with the settlement and termination of the currency swaps.  In the year ended December 31, 2018, we recognized a loss of $11 million, 
recorded in other, net, associated with the currency swaps. 

Note 10—Income Taxes 

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

Tax provision and rate—Our provision for income taxes is based on the tax laws and rates applicable in the  jurisdictions  in 
which we operate and earn income.  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

At  December 31,  2018  and  2017,  our  deferred  tax  assets  included  U.S.  foreign  tax  credit  carryforwards  of  $11 million  and 
$37 million,  respectively,  which  will  expire  between  2019  and  2028.    The  deferred  tax  assets  related  to  our  net  operating  losses  were 
generated in various worldwide tax jurisdictions.  At December 31, 2018, the net operating losses carryforwards, which were generated in 
various jurisdictions worldwide, included $307 million that do not expire and $172 million that will expire beginning between 2021 and 2038.  
At  December 31,  2017,  the  net  operating  losses  carryforwards,  which  were  generated  in  various  jurisdictions  worldwide,  included 
$261 million that do not expire and $174 million that will expire beginning between 2020 and 2037. 

As  of  December 31,  2018,  our  consolidated  cumulative  loss  incurred  over  the  recent  three-year  period  was  primarily  due  to 
losses on impairment and disposal of assets, which represented significant objective negative evidence for our evaluation of our deferred 
tax assets.  Although such evidence has limited our ability to consider other subjective evidence, we analyze each jurisdiction separately.  
We consider objective evidence, such as contract backlog activity, in jurisdictions in which we have profitable contracts.  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,  2018  and  2017,  due  to  uncertainty  of  realization,  we  have  recorded  a 
valuation allowance of $681 million and $574 million, respectively, on net operating losses and other deferred tax assets. 

Our other deferred tax liabilities include taxes related to the earnings of certain subsidiaries that are not indefinitely reinvested or 
that will not be indefinitely reinvested in the future.  We consider the earnings of certain of our subsidiaries to be indefinitely reinvested.  As 
of December 31, 2018, we did not provide for deferred taxes on earnings of certain subsidiaries that are indefinitely reinvested because it 
is not practical to estimate the amount of tax that would ultimately be due if remitted.  If we were to make a distribution from the unremitted 
earnings of these subsidiaries, we would be subject to taxes payable to various jurisdictions.  If our expectations were to change regarding

future tax consequences, we may be required to record additional deferred taxes that could have a material effect on our consolidated

In the years ended December 31, 2018, 2017 and 2016, we recognized, as a component of our income tax provision, expense of 
$13 million, income of $9 million and income of $23 million, respectively, related to previously recognized interest and penalties associated 
with  our  unrecognized  tax  benefits.    As  of  December 31,  2018,  if  recognized,  $514 million  of  our  unrecognized  tax  benefits,  including 
interest and penalties, would favorably impact our effective tax rate. 

It is reasonably possible that our existing liabilities for unrecognized tax benefits may increase or decrease in the year ending 
December 31,  2019,  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. 

U.S.  tax  reform—In  December 2017,  the  U.S.  enacted  the  2017 Tax Act,  which  amended  existing  U.S.  tax  laws  that  had  an 
impact  on  our  income  tax  provision,  such  as  a  base  erosion  and  anti-abuse  tax  (“BEAT”),  a  global  intangible  low-taxed  income  tax, 
additional limitations on the deductibility of executive compensation and interest and the repeal of the domestic manufacturing deduction.  
In  the  years  ended  December 31,  2018  and  2017,  we  recognized  the  income  tax  effects  of  the  2017 Tax Act  in  accordance  with  Staff 
Accounting Bulletin No. 118 (“SAB 118”), which provides SEC staff guidance for the application of accounting standards for income taxes 
in  the  reporting  period  in  which  the  2017 Tax Act  was  enacted.    Although  we  have  completed  our  analysis  and  recorded  the  resulting 
impact of the 2017 Tax Act, the U.S. Congress or Treasury may introduce clarifications, modification or amendments that could cause us 
to make further adjustments in future periods. 

In the year ended December 31, 2017, we recognized income tax expense of $66 million with a corresponding decrease to our 

net deferred tax assets to reflect the reduction in the U.S. corporate income tax rate from 35 percent to 21 percent. 

In  the  year  ended  December 31,  2018,  we  recognized  income  tax  expense  of  $33 million  related  to  the  bareboat  charter 
structure of our U.S. operations because we concluded it is subject to BEAT.  A significant portion of our BEAT liability is contractually 
reimbursable by our customers due to a change-in-law provision in certain drilling contracts. 

The 2017 Tax Act imposes a one-time transition tax on certain unremitted earnings and profits of our non-U.S. subsidiaries that 
are owned by U.S. subsidiaries.  At December 31, 2017, we did not have the necessary information available, prepared and analyzed to 
develop a reasonable estimate of the transition tax.  In the year ended December 31, 2018, we completed our evaluation, and we recorded 
income tax expense of $103 million for estimated transition taxes and an income tax benefit of $16 million for the estimated effect on the 
utilization of foreign tax credits. 

Tax returns—We file federal and local tax returns in several jurisdictions throughout the world.  With few exceptions, we are no 
longer subject to examinations of our U.S. and non-U.S. tax matters for years prior to 2011.  Our tax returns in the major jurisdictions in 
which we operate, other than Brazil, as mentioned below, are generally subject to examination for periods ranging from three to six years.  
We  have  agreed  to  extensions  beyond  the  statute  of  limitations  in  two major  jurisdictions  for  up  to  20 years.    Tax  authorities  in  certain 
jurisdictions are  examining our tax returns and  in some  cases have issued assessments.   We are defending our tax positions in those 
jurisdictions.  While we cannot predict or provide assurance as to the timing or the outcome of these proceedings, we do not expect the 
ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations, although it 
may 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  January 25,  2008,  we  filed  a  protest  letter  with  the  Brazilian  tax  authorities  for  these  tax 
assessments, and we are currently engaged in the appeals process.  In May 19, 2014, the Brazilian tax authorities issued an additional tax 
assessment  for  the  years 2009  and  2010,  and  in  June 18,  2014,  we  filed  protests  with  the  Brazilian  tax  authorities  for  these  tax 
assessments.    In  September 2018,  a  portion  of  one of  the  cases  was  favorably  closed.    As  of  December 31,  2018,  the  remaining 
aggregate tax assessment was for BRL 973 million, equivalent to approximately $251 million, including penalties and interest.  We believe 
our  returns  are  materially  correct  as  filed,  and  we  are  vigorously  contesting  these  assessments.    An  unfavorable  outcome  on  these 
proposed assessments could result in a material adverse effect on our consolidated statement of financial position, results of operations or 
cash flows. 

Other 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.  From time to time, we may identify changes to previously 
evaluated  tax  positions  that  could  result  in  adjustments  to  our  recorded  assets  and  liabilities.    Although  we  are  unable  to  predict  the 
outcome of these changes, we do not expect the effect, if any, resulting from these adjustments to have a material adverse effect on our 
consolidated statement of financial position, results of operations or cash flows.

Note 12—Postemployment Benefit Plans 

Defined benefit pension and other postemployment benefit plans 

Overview—As  of  December 31,  2018,  we  had  defined  benefit  plans  in  the  U.S.,  the  United  Kingdom  (“U.K.”),  and  Norway.  
Benefits under the defined benefit plans in the U.S. and the U.K. have ceased accruing.  We maintain the respective pension obligations 
under such plans until they have been fully satisfied. 

As  of  December 31,  2018,  the  defined  benefit  plans  in  the  U.S.  included  three  funded  and  three  unfunded  plans  (the  “U.S. 
Plans”).  As of December 31, 2018, the defined benefit plan in the U.K. included one funded plan (the “U.K. Plan”).  As of December 31, 
2018,  the  defined  benefit  plans  in  Norway,  primarily  group  pension  schemes  with  life  insurance  companies,  included  three funded  and 
two unfunded  plans  (the  “Norway Plans”),  one of  which  we  assumed  in  our  acquisition  of  Songa.    We  refer  to  the  U.K. Plan  and  the 
Norway Plans,  collectively,  as  the  “Non-U.S. Plans.”    We  refer  to  the  U.S.  Plans  and  the  Non-U.S. Plans,  collectively,  as  the 
“Transocean Plans”.    Additionally,  we  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.

Plan  assets—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.  For the Norway Plans, we establish minimum 
rates  of  return  under  the  terms  of  investment  contracts  with  insurance  companies.    As  of  December 31,  2018  and  2017,  the 
weighted-average target and actual allocations of the investments for the funded Transocean Plans were as follows:

The  U.S. Plans  and  the  U.K. Plan  invest  primarily  in  passively  managed  funds  that  reference  market  indices.    The  funded 
Norway Plans are subject to contractual terms under selected insurance programs.  Each plan’s 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.  As the 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—In  the  years  ended  December 31,  2018,  2017  and  2016,  we  made  an  aggregate  contribution  of 
$17 million, $15 million and $49 million, respectively, to the Transocean Plans and the OPEB Plans using our cash flows from operations.  
In  the  year  ending  December 31,  2019,  we  expect  to  contribute  $15 million  to  the  Transocean Plans,  and  we  expect  to  fund  benefit 
payments of approximately $3 million for the OPEB Plans as costs are incurred.

Defined contribution plans 

We sponsor defined contribution plans, for our employees, the most significant of which were as follows: (1) a qualified savings 
plan covering certain employees working in the U.S., (2) a non-qualified supplemental plan covering certain eligible employees working in 
the U.S., (3) a qualified savings plan covering certain eligible U.K. employees, (4) a non-qualified savings plan covering certain employees 
working  outside  the  U.S.  and  U.K.  and  (5) various  savings  plans  covering  eligible  employees  working  in  Norway.    In  the  years  ended 
December 31, 2018, 2017 and 2016, we recognized expense of $50 million, $43 million and $51 million, respectively, related to our defined 
contribution plans. 

Note 13—Commitments and Contingencies 

Purchase and service agreement obligations 

We have entered into purchase obligations with shipyards and other contractors related to our newbuild construction programs.  
We have also entered into long-term service agreements with original equipment manufacturers to provide services and parts related to 
our  pressure  control  systems.    The  future  payments  required  under  our  service  agreements  were  estimated  based  on  our  projected 
operating activity and may vary based on actual operating activity.  At December 31, 2018, the aggregate future payments required under 
our purchase obligations and our service agreement obligations were as follows (in millions):

In  connection  with  our  acquisition  of  Ocean Rig,  we  acquired  contracts  relating  to  the  construction  of  two ultra-deepwater 
drillships  Ocean Rig Santorini  and  Ocean Rig Crete.    Included  in  the  above  table,  upon  delivery  of  Ocean Rig Santorini  and 
Ocean Rig Crete in the third quarter of 2019 and third quarter of 2020, respectively, our expected remaining obligations to the shipyard will 
be $360 million and $520 million, respectively.  The shipyard has agreed to finance the expected remaining obligations at an interest rate 
of three percent per annum, payable semiannually, with principal due at maturity in June 2023 and January 2024, respectively. 

Lease obligations 

We have operating lease obligations expiring at various dates, principally for real estate, office space and operating equipment.  
In the years ended December 31, 2018, 2017 and 2016, our rental expense for all operating leases, including operating leases with terms 
of less than one year, was approximately $35 million, $52 million and $45 million, respectively. 

We also have a capital lease obligation, which is due to expire in August 2029.  The capital lease contract has an implicit interest 
rate of 7.8 percent and requires scheduled monthly payments of $6 million through August 2029, after which we will have the right and 
obligation  to  acquire  the  drillship  from  the  lessor  for  one dollar.    In  the  years  ended  December 31,  2018,  2017  and  2016,  depreciation 
expense  associated  with  Petrobras 10000,  the  asset  held  under  capital  lease,  was  $23 million.    At  December 31,  2018  and  2017,  the 
aggregate carrying amount of this asset held under capital lease was as follows (in millions):

Letters of credit and surety bonds 

At December 31, 2018 and 2017, we had outstanding letters of credit totaling $31 million and $29 million, respectively, issued 
under  various  committed  and  uncommitted  credit  lines,  some  of  which  require  cash  collateral,  provided  by  several  banks  to  guarantee 
various contract bidding, performance activities and customs obligations.  At December 31, 2018, the aggregate cash collateral held by 
banks for letters of credit was $5 million.  As is customary in the contract drilling business, we also have various surety bonds in place that 
secure customs obligations related to the importation of our rigs and certain performance and other obligations.  At December 31, 2018 
and 2017, we had outstanding surety bonds totaling $84 million and $51 million, respectively. 

Legal proceedings 

Macondo  well  incident—On  April 22,  2010,  the  ultra-deepwater  floater  Deepwater Horizon  sank  after  a  blowout  of  the 
Macondo well  caused  a  fire  and  explosion  on  the  rig  off  the  coast  of  Louisiana.    At  the  time  of  the  explosion,  Deepwater Horizon  was 
contracted to an affiliate of BP plc. (together with its affiliates, “BP”).  Following the incident, we have been subject to civil and criminal 
claims, as well as causes of action, fines and penalties by local, state and federal governments.  Litigation commenced shortly after the 
incident, and most claims against us were consolidated by the  U.S. Judicial Panel on Multidistrict Litigation and transferred to the U.S. 
District  Court  for  the  Eastern  District  of  Louisiana  (the  “MDL Court”).    A  significant  portion  of  the  contingencies  arising  from  the 
Macondo well incident has now been resolved or is pending release of funds from escrow (see “—PSC Settlement Agreement”).  As for 
any actions not resolved by our previous settlements, including any claims by individuals who opted out of the settlement agreement that 
we  and  the  Plaintiff  Steering  Committee  (the  “PSC”)  filed  with  the  MDL Court  in  May 2015  (the  “PSC  Settlement  Agreement”),  we  will 
vigorously defend those claims and pursue any and all defenses available. 

We  recognized  a  liability  for  the  remaining  estimated  loss  contingencies  associated  with  litigation  resulting  from  the 
Macondo well incident that we believe are probable and for which a reasonable estimate can be made.  At December 31, 2018 and 2017, 
the  liability  for  estimated  loss  contingencies  that  we  believe  are  probable  and  for  which  a  reasonable  estimate  can  be  made  was 
$158 million and $219 million, respectively, recorded in other current liabilities, the majority of which is related to our settlement with the 
PSC. 

PSC  Settlement  Agreement—On  May 29,  2015,  together  with  the  PSC,  we  filed  the  PSC Settlement  Agreement  with  the 
MDL Court  for  approval.    Through  the  PSC Settlement  Agreement,  we  agreed  to  pay  a  total  of  $212 million,  plus  up  to  $25 million  for 
partial reimbursement of attorneys’ fees, to be allocated between two classes of plaintiffs as follows: (1) 72.8 percent to private plaintiffs, 
businesses,  and  local  governments  who  could  have  asserted  punitive  damages  claims  against  us  under  general  maritime  law;  and 
(2) 27.2 percent to private plaintiffs who previously settled economic damages claims against BP and were assigned certain claims BP had 
made  against  us.    In  exchange  for  these  payments,  each  of  the  classes  agreed  to  release  all  respective  claims  it  has  against  us.  
Thirty claimants  elected  to  opt  out  of  the  PSC Settlement  Agreement.    In  June 2016  and  August 2015,  we  made  a  cash  deposit  of 
$25 million and $212 million, respectively, into an escrow account established by the MDL Court for the settlement.  On February 15, 2017, 
the MDL Court entered a final order and judgement approving the PSC Settlement Agreement, which is no longer subject to appeal.  In 
November 2017,  the  MDL Court  released  $25 million  from  the  escrow  account  for  payment  of  attorneys’  fees.    In  November 2018,  the 
MDL Court released $58 million from the escrow account as the first installment to the plaintiffs.   At December 31, 2018 and 2017, the 
aggregate  cash  balance  in  escrow  account  was  $156 million  and  $212 million,  respectively,  recorded  in  restricted  cash  accounts  and 
investments.  We expect the remaining funds to be released in March 2019. 

Plea  Agreement—Pursuant 

to 
one misdemeanor  count  of  negligently  discharging  oil  into  the  U.S.  Gulf  of  Mexico,  in  violation  of  the  Clean  Water  Act,  for  which  our 
subsidiary is no longer subject to probation.  We also agreed to make an aggregate cash payment of $400 million, including a criminal fine

and  certain  cash  contributions  payable  in  scheduled  installments.    In  the  years  ended  December 31,  2017  and  2016,  we  made  a  cash 
payment of $60 million in each year, representing the final installments for our obligations under the Plea Agreement. 

Global Marine litigation—On November 28, 2017, Wilmington Trust Company, in its capacity as trustee, filed a lawsuit in the 
Supreme  Court  of  the  State  of  New  York,  County  of  New  York,  against  Global  Marine Inc.  (“Global Marine”),  one of  our  wholly  owned, 
indirect  subsidiaries,  seeking  a  declaratory  judgment  that  Global Marine  is  in  default  under  the  indenture  governing  its  $300 million  of 
outstanding 7.00% Notes due June 2028.  We disagree with the assertions in the lawsuit and believe that Global Marine is in compliance 
with the indenture and has meritorious defenses against these allegations, although it can make no assurance regarding the outcome of 
the lawsuit, including the actual amount that would be due in the event that the lawsuit is successful.  The notes are neither guaranteed by, 
nor recourse to, Transocean Ltd. or our other subsidiaries.  The claimants seek payment prior to the scheduled maturity of the principal 
amount  of  notes  outstanding  and  accrued  but  unpaid  interest  as  well  as  make-whole  amounts  under  the  indenture.    In  addition,  the 
acceleration of the amounts due under the indenture could, absent our payment of the amounts due or otherwise staying any judgment 
therefrom, result in an event of default under our currently undrawn Secured Credit Facility.  We intend to vigorously defend the lawsuit.  
While  we  cannot  predict  or  provide  assurance  as  to  the  outcome  of  these  proceedings,  we  do  not  expect  the  proceedings  to  have  a 
material adverse effect on our consolidated statement of financial position, results of operations or cash flows. 

Nigerian  customer  arbitration—One  of  our  customers  in  Nigeria  owes  us  approximately  $80 million  for  drilling  services 
performed in 2014 and 2015.  The customer has not disputed the services rendered and we have remained engaged in discussions with 
the  customer  about  collection  of  this  overdue  balance.    In  September 2018,  we  notified  the  customer  of  our  intentions  to  enter  into 
arbitration.    We  intend  to  vigorously  pursue  full  recovery  of  this  receivable.    While  we  cannot  predict  or  provide  assurance  as  to  its 
outcome, we do not expect it to have a material adverse effect on our consolidated statement of financial position, results of operations or 
cash flows. 

Nigerian Cabotage Act litigation—In October 2007, three of our subsidiaries were each served a Notice and Demand from the 
Nigeria  Maritime  Administration  and  Safety  Agency,  imposing  a  two percent  surcharge  on  the  value  of  all  contracts  performed by  us  in 
Nigeria pursuant to the Coastal and Inland Shipping (Cabotage) Act 2003 (the “Cabotage Act”).  Our subsidiaries each filed an originating 
summons  in  the  Federal  High  Court  in  Lagos  challenging  the  imposition  of  this  surcharge  on  the  basis  that  the  Cabotage Act  and 
associated levy is not applicable to drilling rigs.  The respondents challenged the competence of the suits on several procedural grounds.  
The court upheld the objections and dismissed the suits.  In December 2010, our subsidiaries filed a new joint Cabotage Act suit.  While 
we cannot predict or provide assurance as to the outcome of these proceedings, we do not expect the proceedings to have a material 
adverse effect on our consolidated statement of financial position, results of operations or cash flows. 

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.  
At December 31, 2018, nine plaintiffs have claims pending in Louisiana, 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  are  not  certain  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 has been 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, 2018, the subsidiary was a 
defendant in approximately 156 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 September 2018, the 
subsidiary  and  certain  insurers  agreed  to  a  settlement  of  outstanding  disputes  that  leaves  the  subsidiary  with  funding,  including  cash, 
annuities  and  coverage  in  place  settlement  agreements  with  insurers,  that  we  believe  will  be  sufficient  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  tax  matters,  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 

AR-81 

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

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  various  hazardous  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.  Liability is 
strict and can be joint and several. 

One of our subsidiaries has been 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 with the Environmental Protection Agency (the “EPA”) and the Department of 
Justice to settle our potential liabilities by remediating the site.  Under a participation agreement, the parties to the settlement completed 
the required remediation, and we believe our share, approximately eight percent, of the ongoing future operation and maintenance costs is 
not material.  We have no reason to believe that any additional potential liabilities for the site will be material. 

One of our subsidiaries was ordered by the California Regional Water Quality Control Board (“CRWQCB”) to develop a testing 
plan for a site known as Campus 1000 Fremont in Alhambra, California, which is now a part of the San Gabriel Valley, Area 3, Superfund 
site.  We were also advised that one or more of our subsidiaries that formerly owned and operated the site would likely be named as a 
PRP or PRPs.  The current property owner, an unrelated party, performed the required testing and detected no contaminants, and based 
on such results, we would contest any potential liability.  In discussions with CRWQCB staff, we were advised of their intent to issue us a 
“no further action” letter, but it has not yet been received.  We have no knowledge of the potential cost of any remediation, who else will be 
named as PRPs, and whether in fact any of our subsidiaries is a responsible party.  The subsidiaries in question do not own any operating 
assets and have limited ability to respond to any liabilities. 

Resolutions of other claims by the EPA, the involved state agency or PRPs are at various stages of investigation.  It is difficult to 
quantify the potential cost of environmental matters and remediation obligations.  Nevertheless, based on the available information, we do 
not  expect  the  ultimate  liability,  if  any,  resulting  from  all  environmental  matters,  including  the  liability  for  all  related  pending  legal 
proceedings, asserted legal claims and known potential legal claims that are likely to be asserted, to have a material adverse effect on our 
consolidated statement of financial position, results of operations or cash flows. 

Note 14—Equity 

Redeemable  noncontrolling  interest—Until  June 11,  2018,  we  owned  a  65 percent  interest  in  Angola  Deepwater  Drilling 
Company Ltd.  (“ADDCL”),  a  Cayman  Islands  company  and  variable  interest  entity  for  which  we  concluded  that  we  were  the  primary 
beneficiary.    Angco  Cayman Limited  (“Angco Cayman”)  owned  the  remaining  a  35 percent  interest  in  ADDCL.    Under  the  terms  of 
ADDCL’s governing documents, Angco Cayman had the right to require us to purchase its interest in ADDCL for cash, and accordingly, we 
presented the carrying amount of Angco Cayman’s ownership interest as redeemable noncontrolling interest on our consolidated balance 
sheets.  We also had the right under ADDCL’s governing documents to require Angco Cayman to sell us its interest, and we exercised that 
right.  On June 11, 2018, pursuant to a settlement requiring no cash payment, we acquired the interests in ADDCL not previously owned 
by  us,  and  ADDCL  became  our  wholly  owned  subsidiary.    In  connection  with  the  acquisition,  we  reclassified  the  $53 million  aggregate 
carrying amount of the redeemable noncontrolling interest to additional paid-in capital.  At December 31, 2017, the carrying amount of the 
assets and liabilities of ADDCL, after eliminating the effect of intercompany transactions, was $716 million and $7 million, respectively. 

Noncontrolling interest—Transocean Partners LLC, a Marshall Islands limited liability company (“Transocean Partners”), was 
previously a partially owned subsidiary.  In the year ended December 31, 2016, Transocean Partners declared and paid a distribution to its 
unitholders,  of  which  the  holders  of  noncontrolling  interest  were  paid  $28 million.    On  December 9,  2016,  Transocean Partners  merged 
with  one of  our  subsidiaries  as  contemplated  under  the  merger  agreement  and  became  our  wholly  owned  subsidiary.    Each 
Transocean Partners  common  unit  that  was  issued  and  outstanding  immediately  prior  to  the  closing,  other  than  the  units  held  by 
Transocean  and  its  subsidiaries,  was  converted  into  the  right  to  receive  1.20 of  our  shares.    To  complete  the  merger,  we  issued 
23.8 million shares from conditional capital. 

Extraordinary general meetings—On November 29, 2018, in connection with the Ocean Rig acquisition, shareholders at our 
extraordinary  general  meeting  approved:  (1) an  amendment  of  our  articles  of  association  to  create  additional  authorized  share  capital, 
(2) the issuance of up to 147.7 million Transocean Ltd. shares and (3) the deletion of the previously approved special purpose authorized 
share  capital.    On  January 16,  2018,  in  connection  with  the  Songa  acquisition,  shareholders  at  our  extraordinary  general  meeting 
approved:  (1) the  issuance  of  up  to  68.6 million  Transocean Ltd.  shares,  (2) an  amendment  of  our  articles  of  association  to  create 
additional authorized share capital, (3) the election of a new director to our board of directors and (4) the issuance of consideration shares 
from our authorized share capital and shares issuable upon exchange of the Exchangeable Bonds.

Par value reduction—On October 29, 2015, at our extraordinary general meeting, our shareholders approved the reduction of 
the par value of each of our shares to CHF 0.10 from the original par value of CHF 15.00.  The reduction of par value became effective as 
of January 7, 2016 upon registration in the commercial register. 

Shares held in treasury—In May 2009, at our annual general meeting, our shareholders approved and authorized our board of 
directors,  at  its  discretion,  to  repurchase  an  amount  of  our  shares  for  cancellation  with  an  aggregate  purchase  price  of  up  to 
CHF 3.5 billion.  On February 12, 2010, our board of directors authorized our management to implement the share repurchase program.  
During  the  three-year  period  ended  December 31,  2017,  we  did  not  purchase  any  shares  under  our  share  repurchase  program.    At 
December 31, 2015, we held 2.9 million shares in treasury, recorded at cost.  On October 29, 2015, at our extraordinary general meeting, 
our shareholders approved the cancellation of the 2.9 million shares previously purchased under the share repurchase program and held 
in treasury, and such cancellation became effective as of January 7, 2016 upon registration in the commercial register. 

Shares held by subsidiaries—One of our subsidiaries holds our shares for future use to satisfy our obligations to deliver shares 
in connection with awards granted under our incentive plans or other rights to acquire our shares.  At December 31, 2018, our subsidiary 
held 0.9 million shares.  At December 31, 2017, two of our subsidiaries, together, held 3.6 million of our shares for this purpose. 

Accumulated other comprehensive loss—The changes in accumulated other comprehensive loss, presented net of tax, for 

our defined benefit pension plans were as follows (in millions):

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.  Our 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, 2018, we had 32.7 million shares authorized and 15.0 million shares available to be 
granted under the Long-Term Incentive Plan.  At December 31, 2018, the total unrecognized compensation cost related to our unvested 
share-based awards was $37 million, which is expected to be recognized 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.    Performance  awards  typically  are  subject  to  a  three-year  measurement 
period during which the number of options or shares to be issued remains uncertain until the end of the measurement period, at which time 
the awarded number of options or shares to be issued is determined.  The performance awards typically vest in one aggregate installment 
following the determination date.  Stock options are subject to a stated vesting period and, once vested, typically have a seven-year term 
during which they are exercisable.

We estimated the fair value of each class of financial instruments, for which estimating fair value is practicable, by applying the 

following methods and assumptions: 

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

Short-term investments—The carrying amount of our unrestricted short-term investments represents the historical cost of the 
time deposits in which they are  invested.  The  carrying amount of such short-term investments  approximates fair value because of the 
near-term maturities of the instruments. 

Restricted cash and cash equivalents—The carrying amount of our restricted cash and cash equivalents, which are subject to 
restrictions due to collateral requirements, legislation, regulation or court order approximates fair value due to the near-term maturities of 
the instruments in which the restricted balances are held.  At December 31, 2018, the aggregate carrying amount of such restricted cash 
and cash equivalents was $429 million, including $428 million and $1 million, recorded in current assets and other assets, respectively.  At 
December 31, 2017, the aggregate carrying amount of such restricted cash and cash equivalents was $456 million, including $440 million 
and $16 million, recorded in current assets and other assets, respectively. 

Restricted investments—The carrying amount of our restricted investments, which are subject to restrictions due to court order 
or pledged for security of certain credit arrangements, approximates fair value because of the near-term maturities of the instruments.  At 
December 31, 2018, the aggregate carrying amount of the restricted investments was $123 million, recorded in other current assets.  At 
December 31, 2017, the aggregate carrying amount of the restricted investments was $26 million and $7 million, recorded in current assets 
and other assets, respectively. 

Debt—The carrying amount of  our debt represents the principal  amount, net  of unamortized  discounts, premiums, debt  issue 
costs  and  fair  value  adjustments.    We  measured  the  estimated  fair  value  of  our  debt  using  significant  other  observable  inputs, 
representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. 

Derivative  instruments—The  carrying  amount  of  our  derivative  instruments  represents  the  estimated  fair  value  of  such 
instruments.  We measured the estimated fair value of our derivative instruments using significant other observable inputs, representative 
of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. 

Note 19—Risk Concentration 

Interest  rate  risk—Financial  instruments  that  potentially  subject  us  to  concentrations  of  interest  rate  risk  include  our  cash 
equivalents, short-term investments, restricted cash investments, debt and capital lease obligations.  We are exposed to interest rate risk 
related to our cash equivalents and short-term investments, as the interest income earned on these investments is based on variable or 
short-term interest rates, which change with market interest rates.  We are also exposed to the interest rate risk related to our fixed-rate 
debt when we refinance maturing debt with new debt or when we repurchase debt in open market repurchases. 

Currency  exchange  rate  risk—Our  international  operations  expose  us  to  currency  exchange  rate  risk.    This  risk  is  primarily 
associated with compensation costs of our employees and purchasing costs from non-U.S. suppliers, which are denominated in currencies 
other  than  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. 

Our primary currency exchange rate risk management strategy 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  and  the  impact  of  inflation  on  local  costs,  actual  local  currency 
needs  may  vary  from  those  anticipated  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—Financial  instruments  that  potentially  subject  us  to  concentrations  of  credit  risk  are  primarily  cash  and  cash 

equivalents, short-term investments and trade receivables, both current and long-term. 

We generally maintain our cash, cash equivalents and short-term investments in time deposits at commercial banks with high 
credit ratings or mutual funds, which invest exclusively in high-quality money market instruments.  We limit the amount of exposure to any 
one institution and do not believe we are exposed to any significant credit risk. 

We  earn  our revenues  by  providing  our  drilling  services  to  international  oil  companies,  government-owned  oil  companies  and 
government-controlled  oil  companies.    Receivables  are  dispersed  in  various  countries  (see  Note 20—Operating  Segments,  Geographic 
Analysis and Major Customers).  We establish an allowance for doubtful accounts on a case-by-case basis, considering changes in the 
financial position of a customer, when we believe the required payment of specific amounts owed to us is unlikely to occur.  Although we 
have encountered only isolated credit concerns related to independent oil companies, we occasionally require collateral or other security to 
support customer receivables.  In certain instances, when we determine that collection is not reasonably assured, we may occasionally 
offer extended payment terms and recognize revenues associated with the contract on a cash basis. 

Labor  agreements—We  require  highly  skilled  personnel  to  operate  our  drilling  units.    We  conduct  extensive  personnel 
recruiting,  training  and  safety  programs.    At  December 31,  2018,  we  had  approximately  6,700 employees,  including  approximately 
800 persons  engaged  through  contract  labor  providers.    Approximately  34 percent  of  our  total  workforce,  working  primarily  in  Norway, 
Brazil,  U.K.  and  Australia  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.  These negotiations could result in higher personnel expenses, other 
increased costs or increased operational restrictions as the outcome of such negotiations affect the market for all offshore employees not 
just the union members. 

Note 20—Operating Segments, Geographic Analysis and Major Customers 

Operating segments—We operate in a single, global market for the provision of contract drilling services to our customers.  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.

Since 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.    Although  we  are 
organized  under  the  laws  of  Switzerland,  we  do  not  conduct  any  operations  and  do  not  have  operating  revenues  in  Switzerland.    At 
December 31, 2018 and 2017, the aggregate carrying amount of our long-lived assets located in Switzerland was less than $1 million.

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. 

Major  customers—For  the  year  ended  December 31,  2018,  Royal Dutch Shell plc  (together  with  its  affiliates,  “Shell”), 
Chevron Corporation  (together  with  its  affiliates,  “Chevron”)  and  Equinor ASA  (together  with  its  affiliates,  “Equinor”)  accounted  for

Note 22—Subsequent Events 

Senior secured notes issuance—On February 1, 2019, we issued $550 million aggregate principal amount of 6.875% senior 
secured  notes  due  February 2027  (the  “6.875% Senior  Secured  Notes”),  and  we  received  approximately  $538 million  aggregate  cash 
proceeds,  net  of  discount  and  issue  costs.    In  connection  with  the  issuance  of  such  notes,  we  were  required  to  deposit  $19 million  in 
restricted cash  accounts to satisfy debt  service requirements.  We are required to pay semiannual installments  of interest only through 
August 2021,  after  which  we  will  pay  semiannual  installments  of  principal  and  interest.    We  may  redeem  all  or  a  portion  of  the 
6.875% Senior Secured Notes at any time prior to February 1, 2022 at a price equal to 100 percent of the aggregate principal amount plus 
a make-whole provision, and on or after February 1, 2022 at specified redemption prices.  We will be required to redeem the notes at a 
price  equal  to  100 percent  of  the  aggregate  principal  amount,  without  a  make-whole  provision,  upon  the  occurrence  of  certain  events 
related  to  the  collateral  rig  and  the  related  drilling  contract.    The  indenture  that  governs  the  6.875% Senior  Secured  Notes  contains 
covenants that limit the ability of our subsidiaries that own or operate the collateral rig to declare or pay dividends to their affiliates.  The 
indenture also imposes a Maximum Collateral Ratio, represented by the net earnings of the rig relative to the debt balance, that changes 
over  the  term  of  the  notes.    Through  December 31,  2020,  the  Maximum  Collateral  Ratio  under  the  indenture  is  5.75 to  1.00.    The 
6.875% Senior Secured Notes are secured by the assets and earnings associated with the ultra-deepwater floater Deepwater Poseidon 
and the equity of the wholly owned subsidiaries that own or operate the collateral rig. 

Debt tender offers—On February 5, 2019, we completed tender offers (the “2019 Tender Offers”) to purchase for cash up to 
$700 million aggregate purchase price of our 6.50% senior notes due November 2020 (the “6.50% Senior Notes”), 6.375% Senior Notes, 
3.80% Senior Notes and 9.00% Senior Notes (collectively, the “2019 Tendered Notes”), subject to the terms and conditions specified in the 
related offer to purchase.  In connection with the 2019 Tender Offers, we received valid tenders from holders of an aggregate principal 
amount of the 2019 Tendered Notes as follows:  $57 million of 6.50% Senior Notes, $63 million  of 6.375% Senior Notes, $190 million of 
3.80% Senior Notes, and $200 million of 9.00% Senior Notes.  In January and February 2019, as a result of the 2019 Tender Offers, we 
made  an  aggregate  cash  payment  of  $521 million  to  settle  the  validly  tendered  2019 Tendered  Notes.    In  the  three months  ending 
March 31, 2019, we expect to recognize an aggregate net loss of approximately $18 million associated with the retirement of debt. 

Assets  held  for  sales—Subsequent  to  December 31,  2018,  we  committed  to  plans  to  sell  the  ultra-deepwater  floater 
Ocean Rig Paros  and  the  harsh  environment  floater  Eirik Raude  and  related  assets.    At  December 31,  2018,  the  aggregate  carrying 
amount of the assets was $12 million.

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  and  our  Chief  Financial  Officer,  to  allow  timely  decisions  regarding  required 
disclosure and (2) recorded, processed, summarized and reported within the time periods specified in the United States (“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, 2018. 

Internal control over financial reporting—There has been no change to our internal control over financial reporting during the 
quarter ended December 31, 2018 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

To the General Meeting of  

Transocean Ltd., Steinhausen  

Zurich, February 19, 2019 

Report of the statutory auditor on the financial statements 

As statutory auditor, we have audited the financial statements of Transocean Ltd., which comprise the statement of operations, balance 
sheet and notes (pages SR-3 to SR-11), for the year ended December 31, 2018. 

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

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

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

Opinion 
In  our  opinion,  the  financial  statements  for  the  year  ended  December 31,  2018  comply  with  Swiss  law  and  the  company’s  articles  of 
incorporation. 

Report on Key Audit Matters based on the circular 1/2015 of the Federal Audit Oversight Authority 
Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of 
the current period.  These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our 
opinion  thereon,  and  we  do  not  provide  a  separate  opinion  on  these  matters.    For  the  matter  below,  our  description  of  how  our  audit 
addressed the matter is provided in that context. 

We  have  fulfilled  the  responsibilities  described  in  the  Auditor’s  responsibilities  section  of  our  report,  including  in  relation  to  this  matter.  
Accordingly,  our  audit  included  the  performance  of  procedures  designed  to  respond  to  our  assessment  of  the  risks  of  material 
misstatement of the financial statements.  The results of our audit procedures, including the procedures performed to address the matter 
below, provide the basis for our audit opinion on the financial statements. 

SR-1 

 
 
 
 
 
 
 
 
 
 
 
Impairment assessment of investments in subsidiaries  

Area of 
emphasis 

Transocean Ltd. evaluates its investments in subsidiaries for impairment annually and records an impairment loss 
when the carrying amount of such assets exceeds the recoverable amount.  The assessment of the existence of 
any indicators of impairment of the carrying amount of investments in subsidiaries is judgmental.  In the event that 
indicators  of  impairment  are  identified,  the  assessment  of  the  recoverable  amounts  is  also  judgmental  and 
requires estimation and the use of subjective assumptions. 

Transocean Ltd.  measures  the  recoverable  amount  of  its  investments  in  subsidiaries  by  applying  a  variety  of 
valuation methods, incorporating a combination of income and market approaches and using projected discounted 
cash flows. 

The  primary  risks  are  identifying  impairment  indicators,  inaccurate  models  being  used  for  the  impairment 
assessment, and that the assumptions to support the value of the investments are inappropriate.  The principal 
consideration for our determination that the impairment assessment of investments in subsidiaries is a key audit 
matter is the subjectivity in the assessment of the recoverable amounts which requires estimation and the use of 
subjective assumptions. 

See Note 3 to these financial statements for Transocean Ltd.’s disclosures related to investment in subsidiaries.  

Our audit 
response 

Our audit procedures related to the key audit matter of the impairment assessment of investments in subsidiaries 
included the following procedures: 

We performed inquiries of management about the current market conditions supporting the evaluation of potential 
impairment  indicators,  tested  the  key  assumptions  used,  and  performed  procedures  on  Transocean Ltd.’s 
prospective financial information. 

We involved valuation specialists to assist in the evaluation of  management’s valuation models and impairment 
analyses, specifically in testing key assumptions and prospective financial information. 

We performed procedures to assess the valuation models for evidence of management bias considering contrary 
evidence from third party analyst reports and press releases. 

Report on other legal requirements 
We  confirm  that  we  meet  the  legal  requirements  on  licensing  according  to  the  Auditor  Oversight  Act  (AOA)  and  independence 
(article 728 CO and article 11 AOA) and that there are no circumstances incompatible with our independence. 

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

We recommend that the financial statements submitted to you be approved.

NOTES TO STATUTORY FINANCIAL STATEMENTS 

Note 1—General 

Transocean Ltd. (the “Company”, “we”, “us”, or “our”) is the parent company of Transocean Inc. and Transocean Management 
Services GmbH., our direct wholly owned subsidiaries.  Transocean Ltd. is registered with the commercial register in the canton of Zug, 
and its shares are listed on the New York Stock Exchange.  At December 31, 2018 and 2017, we had less than 10 full-time employees. 

On January 30, 2018, we acquired an approximate 97.7 percent ownership interest in Songa Offshore SE (“Songa”), a European 
public  company  limited  by  shares,  or  societas  Europaea,  existing  under  the  laws  of  Cyprus.    On  March 28,  2018,  we  acquired  the 
remaining shares not owned by us through a compulsory acquisition under Cyprus law, and as a result, Songa became our wholly owned 
subsidiary.  In connection with these transactions, we issued 68.0 million shares and Transocean Inc. issued USD 863 million aggregate 
principal  amount  of  0.5% exchangeable  senior  bonds  due  January 30,  2023  (the  “Exchangeable  Bonds”).    On  March 28,  2018, 
immediately after completing these transactions, we contributed all shares of Songa to Transocean Inc. 

On  December 5,  2018,  we  acquired  Ocean  Rig  UDW Inc.  (“Ocean Rig”),  a  Cayman  Islands  exempted  company  with  limited 
liability, in a merger transaction, and as a result, Ocean Rig became our wholly owned subsidiary.  In connection with the acquisition, we 
issued 147.7 million shares and made an aggregate cash payment of USD 1.2 billion.  On December 7, 2018, we contributed all shares of 
Ocean Rig to Transocean Inc. 

Note 2—Significant Accounting Policies 

Presentation—We  have  prepared  our  unconsolidated  statutory  financial  statements  in  accordance  with  the  accounting 
principles  as  set  out  in  Art. 957  to  Art. 963b,  of  the  Swiss  Code  of  Obligations  (the  “CO”).    Since  we  have  prepared  our  consolidated 
financial  statements  in  accordance  with  U.S.  generally  accepted  accounting  standards,  a  recognized  accounting  standard,  we  have,  in 
accordance with the CO, elected to forego presenting the statement of cash flows, the additional disclosures and the management report 
otherwise required by the CO.  Our financial statements may be influenced by the creation and release of excess reserves. 

Currency—We  maintain  our  accounting  records  in  U.S. dollars  and  translate  them  into  Swiss francs  for  statutory  reporting 
purposes.    We  translate  into  Swiss francs  our  assets  and  liabilities  that  are  denominated  in  non-Swiss  currencies  using  the  year-end 
currency  exchange  rates,  except  prior-year  transactions  for  our  investments  in  subsidiaries  and  our  shareholders’  equity,  which  are 
translated at historical exchange rates.  We translate into Swiss francs our income statement transactions that are denominated in non-
Swiss currencies using the average currency exchange rates for the year. 

Our principal exchange rates were as follows: 

CHF / USD 
CHF / GBP 
CHF / NOK

We  recognize  realized  currency  exchange  and  translation  gains  and  losses  arising  from  business  transactions  and  net 
unrealized  currency  exchange  and  translation  losses  in  current  period  earnings.    We  defer  net  unrealized  currency  exchange  and 
translation gains and record such deferred gains in other current liabilities. 

Cash—We hold cash balances, denominated in Swiss francs and U.S. dollars, which include cash deposited in demand bank 

accounts, money market investment accounts and other liquid investments and interest earned on such cash balances. 

Current assets and liabilities—We record current assets at historical cost less adjustments for impairment of value and current 

liabilities at historical cost. 

Investments in subsidiaries—We record our investments in subsidiaries at acquisition cost less adjustments for impairment of 
value.  We evaluate our investments in subsidiaries for impairment annually and record an impairment loss when the carrying amount of 
such assets exceeds the fair value.  We estimate fair value of our investments using a variety of valuation methods, including the income 
and market approaches.  Our estimates of fair value represent a price that would be received to sell the asset in an orderly transaction 
between market participants in the principal market for the asset. 

Own shares—We recognize own shares at acquisition cost, which we present as a deduction from shareholders’ equity at the 

time of acquisition.  For own shares held by subsidiaries, we build a reserve for shares in equity at the respective acquisition costs. 

Related parties—In the meaning of the CO, we consider related parties to be only shareholders, direct and indirect subsidiaries, 

and the board of directors.

a) 

The statutory capital reserve from capital contribution for shares held by subsidiaries represents the aggregate cost of own shares held indirectly by Transocean Ltd. 
through  Transocean Inc.    During  the  years  ended  December 31,  2018  and  2017,  Transocean Inc.  withheld  118,547 and  5,630 own  shares,  respectively,  through  a 
broker arrangement in satisfaction of withholding taxes due by our employees upon the vesting of equity awards granted under our Long-Term Incentive Plan.  For the 
years  ended  December 31,  2018  and  2017,  the  aggregate  value  of  own  share  transactions  was  CHF 1.4 million  and  CHF 51,000,  respectively.    See  Note 5—Own 
Shares. 

Authorized share capital—In May 2016, at our annual general meeting, our shareholders approved an authorized share capital 
in  the  amount  of  CHF 2.2 million,  authorizing  the  issuance  of  a  maximum  of  22.3 million  fully  paid-in  shares  with  a  par  value  of 
CHF 0.10 per share at any time until May 12, 2018. 

In  January 2018,  in  connection  with  the  acquisition  of  Songa,  shareholders  at  our  extraordinary  general  meeting  approved, 
together with other proposals, the issuance of up to 68.6 million of our shares, par value CHF 0.10 each, tendered for a voluntary offer, and 
an amendment of our articles of association to create additional authorized share capital to issue up to 25.4 million registered shares, par 
value  CHF 0.10  each,  in  connection  with  a  compulsory  acquisition  of  the  remaining  Songa  shares  not  owned  by  us  immediately  after 
completion of the voluntary offer. 

In  May 2018,  shareholders  at  our  annual  general  meeting  renewed  the  board  of  directors’  authority  to  issue  shares  out  of 
authorized share capital for a further two-year period, expiring on May 18, 2020.  The board of directors’ authority to issue shares in one or 
several steps is limited to a maximum of 27.7 million shares. 

In November 2018, in connection with the acquisition of Ocean Rig, shareholders at our extraordinary general meeting approved, 
together with other proposals, an amendment of our articles of association to create additional authorized share capital, the issuance of up 
to 147.7 million shares to pay the share consideration in the acquisition of Ocean Rig.  The board of directors utilized the full authorization 
less eight shares for the specified purpose; the remaining authorization is reflected in article 5ter of the Company’s articles of association 
but  may  not  be  used  for  any  purpose  other  than  the  already  completed  acquisition  of  Ocean  Rig.    The  shareholders  at  the  same 
extraordinary general meeting approved the deletion of the previously approved special purpose authorized share capital, in connection 
with  the  acquisition  of  Songa,  included  in  article  5bis  of  the  Company’s  articles  of  association,  which  allowed  for  the  issuance  of  up  to 
24.3 million shares. 

Conditional  share  capital—Our  articles  of  association  provide  for  a  conditional  share  capital  that  permits  us  to  issue  up  to 

143.8 million additional shares, under the following circumstances, without obtaining additional shareholder approval: 

(1)  through  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 convertible into or exercisable or exchangeable for our shares or 
the shares of one of our group companies or any of their respective predecessors; or 

(2)  in  connection  with  the  issuance  of  shares,  options  or  other  share-based  awards  to  directors,  employees,  contractors, 

consultants or other persons providing services to us. 

In  connection  with  the  issuance  of  bonds,  notes,  warrants  or  other  financial  instruments  or  contractual  obligations  that  are 
convertible  into,  exercisable  for  or  exchangeable  for  our  registered  shares,  our  board  of  directors  is  authorized  to  withdraw  or  limit  the 
advance  subscription  rights  of  shareholders  under  certain  circumstances.    In  connection  with  the  issuance  of  shares,  options  or  other 
share-based awards to directors, employees, contractors, consultants or other persons providing services to us, the preemptive rights and

incentive plans  or other rights to acquire our shares.  In the years ended December 31, 2018 and 2017, we transferred 2.6 million and 
1.9 million  shares,  respectively,  at  historical  cost,  from  the  own  shares  held  by  Transocean Inc.  to  satisfy  obligations  under  our 
share-based compensation plans.  In the years ended December 31, 2018 and 2017, we received cash proceeds of CHF 1.4 million and

Note 7—Guarantees, Contingencies and Commitments 

Transocean Inc. and other indirect subsidiaries debt obligations—Transocean Inc., Transocean Phoenix 2 Limited (“TP2L”), 
Transocean Proteus Limited (“TPTL”), Transocean Pontus Limited (“TPOL”) and Transocean Guardian Limited (“TGLtd”) have each issued 
certain debt securities or entered into other credit arrangements, including notes, bank credit agreements, debentures, surety bonds and 
letters of credit.  We have guaranteed certain of these debt securities or other credit arrangements.  With certain exceptions under the 
indentures of the senior secured notes issued by our subsidiaries, we are not subject to any significant restrictions on our ability to obtain 
funds  from  our  consolidated  subsidiaries  by  dividends,  loans  or  return  of  capital  distributions.    At  December 31,  2018  and  2017,  the 
aggregate  carrying  amount  of  debt  that  we  have  guaranteed  was  USD 8.9 billion  and  USD 6.2 billion,  respectively,  equivalent  to 
approximately  CHF 8.7 billion  and  CHF 6.0 billion,  respectively.    In  the  years  ended  December 31,  2018  and  2017,  we  recognized 
guarantee fee income of less than CHF 1 million.  See Note 9—Subsequent Events. 

Macondo well  litigation  settlement  obligations—On  January 3,  2013,  certain  of  our  wholly  owned  subsidiaries  reached 
agreements  with  the  U.S.  Department  of  Justice  (“DOJ”)  to  resolve  certain  matters  arising  from  the  Macondo well  incident.    The 
agreements  included  a  criminal  plea,  pursuant  to  which  one of  our  subsidiaries  pled  guilty  to  one misdemeanor  count  of  negligently 
discharging oil in the U.S. Gulf of Mexico, in violation of the U.S. Clean Water Act, and a civil  consent decree  (the “Consent Decree”), 
which  resolved  certain  claims  by  the  DOJ,  the  U.S.  Environmental  Protection  Agency  and  the  U.S.  Coast  Guard  against  certain  of  our 
subsidiaries (the “Transocean Defendants”) and certain incidents of noncompliance that were alleged by the U.S. Bureau of Safety and 
Environmental Agency.  As part of this resolution, certain of our subsidiaries agreed to pay USD 1.4 billion, equivalent to approximately 
CHF 1.3 billion, in fines, recoveries and civil penalties, excluding interest, payable in installments through February 2017.  We agreed to 
guarantee the scheduled installments and other obligations required of the Transocean Defendants, in exchange for a guarantee fee.  The 
guarantee fee, payable annually from January 1, 2014 to 2017, was equivalent to 1.76 percent of the weighted average daily outstanding 
balance  due  by  the  Transocean  Defendants  over  the  prior  year.    In  the  year  ended  December 31,  2017,  we  recognized  guarantee  fee 
income of less than CHF 1 million.  See Note 9—Subsequent Events. 

Transocean  Management  Services GmbH  office 

lease  obligation—On  June 26,  2018,  Transocean  Management 
Services GmbH assumed responsibility for a lease obligation, originally entered into by its predecessor, Transocean Management Ltd., for 
its former principal offices in Vernier, Switzerland.  Under an uncommitted line of credit, Transocean Ltd. issued a surety bond in the full 
amount of the lease obligation.  At December 31, 2018 and 2017, our guarantee for the lease obligation was CHF 460,000. 

Swiss value added tax—We are one of a group of Swiss entities, which are jointly and severally liable for the whole Swiss value 

added tax amount due to the Swiss tax authorities by this group. 

Note 8—Related Party Transactions 

Transocean Inc.—Transocean Inc. holds our shares to satisfy, on our behalf, our obligation to deliver shares in connection with 
awards  granted under  our  incentive  plans,  warrants  or  other  right  to  acquire  our  shares.    At  December 31,  2018,  Transocean Inc.  held 
0.9 million shares.  At December 31, 2017, Transocean Inc. and TPHL, together, held 3.6 million of our shares for this purpose. 

We  and  Transocean Inc.,  as  the  borrower  and  lender,  respectively,  entered  into  a  credit  agreement  dated  June 1,  2011, 
establishing  a  USD 2.0 billion  revolving  credit  facility.    At  December 31,  2018  and  2017,  we  had  borrowings  of  USD 134 million  and 
USD 53 million,  respectively,  equivalent  to  approximately  CHF 132 million  and  CHF 52 million,  respectively,  outstanding  under  the 
revolving credit facility at a rate of 3.0 percent and 2.5 percent, respectively. 

On January 30, 2018, in connection with the acquisition of Songa, we issued to Transocean Inc. an exchangeable loan note in 
the principal amount of USD 854 million with interest payable semiannually at a rate of 0.5 percent per annum.  On March 28, 2018, we 
issued  a  first  supplemental  indenture  in  the  principal  amount  of  USD 9 million.    At  December 31,  2018,  the  outstanding  principal  of  the 
exchangeable note was USD 863 million, equivalent to approximately CHF 847 million.  Exchangeable loan notes may be converted at any 
time  prior  to  the  maturity date at an exchange rate of 97.29756 shares per $1,000 note, equivalent to a conversion price of $10.28 per 
share, subject to adjustment upon the occurrence of certain events.  Holders of Exchangeable Bonds may require us to repurchase all or a 
portion of such holder’s Exchangeable Bonds upon the occurrence of certain events.

NOTES TO STATUTORY FINANCIAL STATEMENTS—continued 

On November 30, 2018, in connection with the acquisition of Ocean Rig, we and Transocean Inc., as the borrower and lender, 
respectively, entered into a credit agreement establishing a USD 1.2 billion revolving credit facility, expiring December 5, 2024.  Under the 
terms of the agreement, we will pay interest quarterly on outstanding borrowings at a variable rate based on the Swiss Safe Harbor Rate.  
At  December 31,  2018,  we  had  borrowings  of  USD 1.2 billion,  equivalent  to  CHF 1.2 billion,  outstanding  under  the  credit  facility  at  an 
interest rate of 3.0 percent. 

Other  subsidiaries—Our  subsidiaries  perform  on  our  behalf  certain  general  and  administrative  services,  including  executive 
administration,  procurement  and  payables,  treasury  and  cash  management,  personnel  and  payroll,  accounting  and  other  administrative 
functions.  In the years ended December 31, 2018 and 2017, we recognized such costs of CHF 2 million and CHF 10 million, respectively, 
recorded in general and administrative costs and expenses. 

Note 9—Subsequent Events 

Subsidiary  debt  obligations—Subsequent  to  December 31,  2018,  Transocean  Poseidon Limited,  our  indirect  wholly  owned 
subsidiary, issued USD 550 million senior secured notes.  We and Transocean Inc. have each provided a full and unconditional guarantee 
of the senior secured notes. 

Macondo well litigation settlement obligations—On January 2, 2019, as permitted under the Consent Decree, we submitted 
an official termination request to the U.S.  On February 6, 2019, the U.S. submitted a joint stipulation and proposed order (the “Order”) to 
terminate the Consent Decree to the U.S. District Court for the Eastern District of Louisiana (the “Court”), and on February 13, 2019, the 
Court entered the Order.  Accordingly, the Consent Decree is terminated and has no further force or effect on the Company.

the  Standard  &  Poor’s  500  Stock  Index  (“S&P  500”),  the  Standard  &  Poor’s 
MidCap 400 Index (“S&P MidCap 400”) and the Philadelphia Oil Service Sector 
Index (“OSX”) over our last five fiscal years. In 2017, the Company moved to 
the S&P MidCap 400 from the S&P 500 due to a market capitalization below 
$4.5 billion. The graph assumes that $100 was invested in our shares, the S&P 
500 and the S&P MidCap 400, and the OSX on December 31, 2013, and that all 
dividends were reinvested on the date of payment.
