2017 ANNUAL REPORT TO SHAREHOLDERS

ABOUT TRANSOCEAN LTD.

We are a leading international provider of offshore contract drilling services for oil and gas wells. As of 
February 19, 2018, we owned or had partial ownership interests in and operated a fleet of 47 mobile offshore 
drilling units. In addition, we have two newbuild ultra-deepwater drillships under construction or under 
contract to be constructed. The company also operates two high-specification jackups that were under drilling 
contracts when the rigs were sold, and the company continues to operate these jackups until completion or 
novation of the drilling contracts. We specialize in technically demanding sectors of the global offshore drilling 
business with a particular focus on ultra-deepwater and harsh environment drilling services. We believe we 
operate one of the most versatile offshore drilling fleets in the world. 

Our shares are traded on the New York Stock Exchange under the symbol RIG.

The symbols in the map above represent the company’s global market presence as of the February 19, 2018 Fleet Status Report.

OUR GLOBAL MARKET PRESENCEDeepwaterMidwaterUltra-Deepwater271226Harsh Environment 
 
March 19, 2018 

Letter to Shareholders 

While  commodity  prices  improved  throughout  2017,  customers  continued  to  curtail  spending  on  offshore 
exploration  and  development,  further  extending  what  has  become  one  of  the  worst  downturns  in  the  offshore  drilling 
market. Still, through our continued commitment to fleet quality, operational excellence and organizational and operating 
efficiency, Transocean delivered another strong year, producing financial results that once again exceeded expectations. 

As we enter 2018, we are encouraged by improving macro conditions, with recent prices for both Brent and WTI 
surpassing $65 per barrel for the first time in over three years. This increase in oil prices, coupled with the efficiencies and 
resulting cost reductions that the offshore industry has realized over the past three years, has made a significant number of 
offshore projects around the world economically viable. 

As a testament to this fact, the harsh environment markets of Northern Europe and Eastern Canada are now in 
recovery.  Fixtures  have  increased  over  70%  from  2016,  with  utilization  and  dayrates  for  high-specification,  harsh 
environment  semisubmersibles  increasing  by  approximately  20%  and  more  than  50%,  respectively.  In  fact,  growing 
concern around asset availability in this market is driving customers to tender for multi-year programs. 

While certainly not as promising as the harsh environment market, the world’s ultra-deepwater markets are also 
demonstrating signs of improvement. For the first time in over two years, customers are trying to secure some of the more 
technically capable assets by entering into multi-year contracts. Unfortunately, utilization rates for ultra-deepwater assets 
remain low; therefore, leading-edge dayrates in these markets continue to remain challenged. 

In short, we enter 2018 with more optimism than we had in any of the past three years; however, since the precise 
timing and trajectory of the eventual recovery continues to elude us, we will continue to be prudent as we take the necessary 
actions to maintain our industry-leading position and strategically position Transocean to benefit from the recovery ahead. 

We have added contracted rigs to the industry’s most competitive floating fleet, while removing our older, less 
competitive  assets.  Over  the  past  six  months,  we  welcomed  to  our  fleet  the  fourth  and  fifth  newbuild  ultra-deepwater 
drillships, Deepwater Pontus and Deepwater Poseidon. All five of our newbuild assets added since 2016 are backed by 
long-term contracts, and represent some of the most technically capable rigs in the world. In January of 2018, we closed 
the acquisition of Songa Offshore, which added seven semisubmersibles, including four CAT-D high-specification, harsh 
environment  floaters,  the  Equinox,  Endurance,  Encourage  and  Enabler.  These  four  floaters  were  designed  to  the 
specification of our customer, Statoil, and the rigs are on long-term contracts extending out as far as 2024, with each asset 
including follow-on options for twelve additional years. We also opportunistically upgraded our drillship, the Discoverer 
India, which was recently awarded a new contract to work offshore Ivory Coast. The additions of our newbuild drillships 
and  the  harsh  environment  semisubmersibles,  as  well  as  the  enhancement  to  the  Discoverer  India,  have  further 
strengthened  our  position  as  the  industry’s  largest  and  most  capable  ultra-deepwater  and  harsh  environment  drilling 
contractor. 

We continued our fleet high-grading process with the recycling of nine older, less-competitive assets. In total, 
we have retired 39 floaters during the past four years. Also, through the sale of our jackup fleet, we have focused our 
efforts exclusively on the floating rig market, where we believe that we clearly differentiate our service offering as we 
continue to maintain and grow our market-leading position. 

We are adding new contracts to our backlog. In both the improving harsh environment markets and the more 
challenged deep and ultra-deepwater markets throughout the rest of the world, we successfully added fixtures in 2017. 
Over the course of the year, Transocean added almost $900 million of backlog from 25 awards, winning approximately 
20% of the global floater contracts awarded. Our contracting success is directly attributable to our recognized performance 

 
 
in some of the most challenging harsh environment and ultra-deepwater basins around the world. In some situations, our 
success was due to our willingness to propose flexible contracting arrangements that include performance-driven models, 
tying our success to the success of our customers’ drilling programs. Our customers’ trust in our ability to execute enabled 
us to reactivate an additional four floaters during the year for new contracts. Going forward, these assets will be well-
positioned for future opportunities. As of February 19, 2018, our backlog totaled $12.8 billion and includes the lion’s share 
of the industry’s above market, long-term contracts with the industry’s strongest customers. 

We are focused on efficient well delivery. In 2017, we commenced a strategic initiative related to our asset and 
inventory  management  system.  This  initiative  will  focus  on  the  key  areas  of  well  efficiency:  inventory  optimization, 
reliability-centered maintenance, and equipment condition, as well as ensuring the timely availability and precise use of 
parts.  Through  the  thorough  collection,  evaluation  and  use  of  data,  we  are  positioning  the  company  to  operate  our 
equipment  in  the  most  efficient  manner  possible  while  executing  our  customer’s  drilling  plans  better  than  previously 
possible. These actions support a robust condition-based monitoring program that pinpoints early detection of equipment 
issues to best enable us to address these in the most expedient manner, thus reducing downtime and improving our asset 
reliability. Our ability to identify root-causes improves our insight into maintenance planning and execution, as well as 
overall  equipment  health.  This  proactive  management  tool  will  enable  Transocean  to  better  demonstrate  our  value 
proposition to our customers. 

We continue to identify and capitalize on opportunities to further differentiate Transocean. The downturn in 
the energy industry has driven change. It is imperative that we have the most capable assets and operate them in a manner 
that delivers more effectively and efficiently. Building on our prior success of supplier service arrangements related to the 
rigs’ most critical equipment, in 2017, we executed several more agreements again focusing on uptime performance. These 
new agreements cover some of the most important equipment on the rig, including the blowout preventers, thrusters, risers, 
iron roughnecks, top drives, and the drill floor. These agreements rely significantly on condition-based monitoring and 
help keep our rigs drilling while reducing costly downtime and maintenance expenditures. With the involvement of the 
original  equipment  manufacturers,  these  arrangements  also  lengthen  the  time  between  our  costly  periodic  surveys and 
allow for the scheduling of maintenance as needed, as opposed to on a calendar basis. We are excited as we enter 2018. 
The  strategic  and  operational  improvements  we  have  implemented  and  expanded  upon  over  the  last  two  years  should 
continue to enhance our operating performance. 

Enhancing  our  liquidity  runway.  Following  our  financing  successes  in  2016,  we  again  executed  financing 
transactions during the year that further strengthened our liquidity and balance sheet. These actions provide an extended 
runway  that  enables  us  to  successfully  navigate  the  current  industry  downturn,  while  continuing  to  provide  strategic 
optionality. In 2017, we issued approximately $1.2 billion of debt maturing in 2022 and 2026, while retiring $1.8 billion 
of debt with maturities primarily between 2017 and 2020. We additionally removed approximately $1 billion of shipyard 
obligations with the sale of our five uncontracted jackups that were under construction. These transactions, along with our 
outstanding operational performance, positioned us with $3.0 billion of cash and short-term investments entering 2018 
and a $3 billion undrawn, unsecured revolving credit facility. 

We expect 2018 to continue to be challenging as the market remains uncertain and many of our customers remain 

cautious. However, we enter the year with more positive data points than we have seen in three years. 

•  Oil  supply  and  demand  fundamentals  are  improving,  as  OPEC  continues  to  comply  with  its  committed 

production cuts, and the global economy continues to flourish. 

•  Oil prices have more than doubled from their lows in early 2016, and have demonstrated stability and upward 

price momentum since mid-2017. 

•  Global reserve replacement has plummeted to historic lows and the sanctioning of new offshore projects is 
expected  to  replace  only  one-third  of  current  offshore  production  as  global  demand  is  anticipated  to 
accelerate. 

•  Through eliminating, standardizing, streamlining, automating and/or integrating, the offshore industry has 
dramatically reduced the break-even costs for many of our customers’ offshore projects. As (if not more) 
important, the offshore industry has shortened the time to deliver first-oil, which is vital in a market where 
our customers are focused on shorter time horizons for cash returns. 

 
Needless to say, we believe that we could soon be approaching an inflection point in the offshore drilling industry. 
We  appreciate  your patience  and  trust  as we have battled  this  downturn  together. And, we  look  forward  to ultimately 
emerging from this downturn as the undisputed leader in deepwater and harsh environment drilling.

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 Merrill A. “Pete” Miller, Jr. as Chairman of the Board of Directors (Agenda Item 6) and Frederico F. Curado, Vincent 
J. Intrieri and Tan Ek Kia as members of the Compensation Committee (Agenda Item 7) to serve until completion of the 
2019  annual  general  meeting  of  the  shareholders  (the  “2019  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 2018 Annual General Meeting. Swiss companies may only appoint an independent 
proxy for these purposes. At the 2017 annual general meeting of the shareholders (the “2017 Annual General Meeting”), 
shareholders  elected  Schweiger  Advokatur  /  Notariat  to  serve  as  our  independent  proxy  for  the  2018  Annual  General 
Meeting. Agenda Item 8 asks that you again elect this firm to act as the independent proxy for the 2019 Annual General 
Meeting and any extraordinary general meeting of shareholders of the Company that may be held prior to the 2019 Annual 
General Meeting. 

The  Minder  Ordinance  and  our  Articles  of  Association  also  require  that  shareholders  ratify  the  maximum 
aggregate amount of compensation of the Board of Directors for the period between the 2018 Annual General Meeting 
and the 2019 Annual General Meeting (Agenda Item 11A) and the maximum aggregate amount of compensation of the 
Executive Management Team for fiscal year 2019 (Agenda Item 11B). 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 the Company. We believe our executive 

v 

compensation program includes key features that align the interests of our executives with those of our shareholders and 
does not include features that could misalign those interests. 

What We Do 

What We Don’t Do 

(cid:53) Conduct an annual review of our compensation

or special change-in-control compensation 
agreements with any Executive Officers; however, to 
the extent permitted under Swiss law, our executives 
are eligible for severance and change-in-control 
provisions pursuant to our policies 

(cid:53) Base annual and long-term incentive payments on 

quantitative, formulaic metrics 

  (cid:58)  Provide gross-ups for severance payments 

(cid:53) Maintain compensation plans that are weighted 

significantly toward variable pay to align our executive 
compensation with long-term shareholder interests 

  (cid:58)  Guarantee salary increases, non-performance based 
bonuses or unrestricted equity compensation   

(cid:53) Link long-term incentive compensation to relative 
performance metrics to incent strong performance 

  (cid:58)  Provide any payments or reimbursements for tax 

equalization 

(cid:53) Deliver at least 50% of long-term incentives in 

performance-based equity awards 

  (cid:58)  Pay dividend equivalents on performance units that 

have not vested 

(cid:53) Retain an independent consultant who does not 

perform any services for management (i.e., retained by 
and reports to our Compensation Committee)

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 2018 Annual General Meeting. The plurality requirement means
that the nominee who receives the largest number of votes for a board position, 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 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)    The affirmative vote of at least two-thirds of the votes and the absolute majority of the par value of shares, each as present or represented at
the 2018 Annual General Meeting. An abstention, blank or invalid ballot will have the effect of a vote “AGAINST” this proposal. Broker
non-votes are not counted for this agenda item and therefore will have no impact on the approval of this agenda item. 

(5)    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.

that the shares are registered on the books of the Company as being held by the brokers, have the authority to vote on 
“routine” proposals when they have not received instructions from beneficial owners, but are precluded from exercising 
their  voting  discretion  with  respect  to  proposals  for  “non-routine”  matters.  Proxies  submitted  by  brokers  without

forth above and may not be able to vote your shares on other matters at the 2018 Annual General Meeting unless the broker 
receives appropriate instructions from you. We recommend that you contact your broker to exercise your right to vote your 
shares. 

If you have timely submitted electronic or telephonic voting instructions or a properly executed proxy card, your 
shares will be voted by the independent proxy according to your instructions. Holders of shares who have timely submitted 
their proxy, but have not specifically indicated how to vote their shares will be deemed to have instructed the independent 
proxy to vote in accordance with the recommendations of the Board of Directors with regard to the items listed in the

voting is permissible under Swiss law are properly presented at the 2018 Annual General Meeting for consideration, 
you will be deemed to have instructed the independent proxy, in the absence of other specific instructions, to vote 
in accordance with the recommendations of the Board of Directors. 

As of the date of this proxy statement, the Board of Directors is not aware of any such modifications or other 

matters to come before the 2018 Annual General Meeting. 

You may revoke your proxy card at any time prior to its exercise by taking one of the following actions:

AGENDA ITEM 1 

Approval of the 2017 Annual Report, Including the Audited Consolidated Financial Statements of 
Transocean Ltd. for Fiscal Year 2017 and the Audited Statutory Financial Statements of 
Transocean Ltd. for Fiscal Year 2017 

Proposal of the Board of Directors 

The  Board  of  Directors  proposes  that  the  2017  Annual  Report,  including  the  audited  consolidated  financial 
statements of Transocean Ltd. for fiscal year 2017 and the audited statutory financial statements of Transocean Ltd. for 
fiscal year 2017, be approved. 

Explanation 

The  audited  consolidated  financial  statements  of  Transocean Ltd.  for  fiscal year  2017  and  the  audited  Swiss 
statutory financial statements of Transocean Ltd. for fiscal year 2017 are contained in the 2017 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 2017 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 2017 and statutory financial statements for fiscal year 2017. 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,  2017,  be  approved.  Ernst &  Young Ltd  expresses  its 
opinion that the “consolidated financial statements for the years ended December 31, 2017 and 2016 present fairly in all 
material respects the consolidated financial position of Transocean Ltd. and subsidiaries at December 31, 2017 and 2016, 
and the consolidated results of operations and cash flows for each of the three years in the period ended December 31, 
2017,  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 2017 
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. 

Recommendation 

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

P-6 

 
 
AGENDA ITEM 2 

Discharge of the Members of the Board of Directors and the Executive Management Team from 
Liability for Activities During Fiscal Year 2017 

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 and John B. Stobart, who served as members of our Executive Management Team in 2017, be discharged 
from liability for activities during fiscal year 2017. 

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 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 2017. 

Recommendation 

The Board of Directors recommends a vote “FOR” this Agenda Item 2.

Appropriation of the Accumulated Loss for Fiscal Year 2017 and Release of CHF 1,500,000,000 of 
Statutory Capital Reserves from Capital Contribution and Allocation to Free Capital Reserves from 
Capital Contribution 

Proposal of the Board of Directors 

The Board of Directors proposes that (1) the accumulated loss of the Company be carried forward and (2) CHF 
1,500,000,000 of statutory capital reserves from capital contribution be released and allocated to free capital reserves from 
capital contribution.

Explanation 

Under Swiss law, the appropriation of available earnings or accumulated loss, as the case may be, as set forth in 
the Swiss statutory financial statements must be submitted to shareholders for approval at each annual general meeting. 
The  accumulated  loss  subject  to  the  vote  of  the  Company’s  shareholders  at  the  2018  Annual  General  Meeting  is  the 
accumulated loss of Transocean Ltd., on a standalone basis. 

The total accumulated loss as of December 31, 2017, has resulted in our net assets covering about 53% of our 
statutory share capital and statutory capital reserves. Under Swiss law, if assets cover less than 50% of our statutory share 
capital and statutory capital reserves, the Board of Directors must propose measures to address such a capital loss. In light 
of the continuing market uncertainty the Board of Directors believes it is advisable and in the best interest of the Company 
to ensure now that it maintains excess coverage. The Board of Directors proposes that CHF 1,500,000,000 of statutory 
capital  reserves  from  capital  contribution  be  released  and  allocated  to  free  capital  reserves  from  capital  contribution, 
thereby reducing the statutory capital reserves from capital contribution which, unlike free capital reserves, are part of the 
equity capital against which excess coverage is measured. The Board of Directors believes such a release and reallocation 
is in the best interest of shareholders.   

Recommendation 

The Board of Directors recommends a vote “FOR” this Agenda Item 3.

AGENDA ITEM 4 

Renewal of Authorized Share Capital   

Proposal of the Board of Directors   

The Board of Directors proposes that its authority to issue shares out of the Company’s authorized share capital 
be renewed for an additional two-year period, expiring on May 18, 2020. Pursuant to the proposal, the Board of Directors’ 
authority to issue shares in one or several steps under this authorization will be limited to a maximum of 27,703,889 shares, 
or  approximately  6%  of  the  Company’s  share  capital  currently  recorded  in  the  Commercial  Register.  The  Board  of 
Directors does not currently have plans to issue shares under this authorization. The Board of Directors believes, however, 
that  providing  the  flexibility  to  issue  shares  out  of  the  authorized  share  capital  quickly  is  a  strategic  benefit  for  the 
Company.   

The proposed amendments to the Articles of Association are included in Annex A. 

Explanation   

Under the Swiss Code of Obligations, the authority of the Board of Directors to issue shares out of the Company’s 
authorized  share  capital  is  limited  to  a  maximum  two-year  period.  The  Company’s  Articles  of  Association  currently 
include authorized share capital in Articles 5 and 5 bis. 

The authorized share capital in Article 5 is limited to a maximum of 22,258,043 common shares, par value CHF 
0.10, which will expire on May 12, 2018. At the time of shareholder approval in connection with the Company’s 2016 
annual  general  meeting  of  shareholders,  the  authorized  share  capital  pursuant  to  the  current  Article  5  represented 
approximately 6% of the Company’s share capital recorded in the Commercial Register. The proposal of the Board of 
Directors maintains the approximately 6% authorized share capital approved by the shareholders at the Company’s 2016 
annual general meeting of shareholders. Although the Board of Directors has not issued, and does not currently have plans 
to  issue,  shares  from  this  portion of  the  authorized  share capital,  it  believes  the proposed  renewal  of authorized  share 
capital  will  provide  the  Company  with  the  flexibility  to  make  acquisitions  and  access  equity  capital  markets  when 
opportunities arise, rather than being subject to the delays and cost associated with the need to call a shareholders’ meeting 
and obtain further shareholder approval, except as may be required by applicable laws or regulations, including the rules 
of the NYSE. Without the Board of Directors’ authority to issue shares, the Company would be required to first call a 
general meeting of the Company’s shareholders and obtain the favorable vote of shareholders to increase the Company’s 
share capital and amend our Articles of Association. Such a meeting would require us, among other things, to prepare and 
distribute a proxy statement in accordance with the rules of the SEC. This could result in a substantial delay in the ability 
of the Company to issue shares. The Board of Directors believes that providing the flexibility to issue shares out of the 
authorized share capital quickly is a strategic benefit for the Company. 

The  separate  authorized  share  capital  in  Article  5bis  was  approved  at  the  Extraordinary  General  Meeting  of 
Shareholders convened by the Company on January 16, 2018, related to the previously-disclosed acquisition of Songa 
Offshore SE that closed on January 30, 2018. Article 5bis was approved by our shareholders solely for use in connection 
with the compulsory acquisition of or mandatory offer for the shares of Songa Offshore SE that were not acquired by the 
Company in the voluntary tender offer for all issued and outstanding shares of Songa Offshore SE. It is therefore unrelated 
to the proposed renewal of authorized share capital in Article 5. 

If the proposed renewal of authorized share capital is approved, and the Board of Directors resolves to use the 
authorized share capital in one or several steps, the Board of Directors will determine the time of the issuance, the issuance 
price, the manner in which the shares have to be paid, the date from which the shares carry the right to dividends and, 
subject to the provisions of our Articles of Association, the conditions for the exercise of the preemptive rights with respect 
to the issuance and the allotment of preemptive rights that are not exercised. Further authorization for the issuance of the 
shares by a vote of our shareholders will not be solicited prior to such issuance. 

To the extent that shares are issued out of the authorized share capital in the future, the issuance may decrease 
the existing shareholders’ percentage of equity ownership and, depending on the price at which such shares are issued, 
could be dilutive to the existing shareholders up to the amount of the authorized capital proposed above.   

P-9 

 
 
 
The Board of Directors may allow preemptive rights that are not exercised to expire, or it may place such rights 
or  shares,  the  preemptive  rights  of  which  have  not  been  exercised,  at  market  conditions  or  use  them  otherwise  in  the 
Company’s interest. Further, under our Articles of Association, in connection with the issuance of shares from authorized 
capital, the Board of Directors is authorized to limit or withdraw the preemptive rights of the existing shareholders in 
various circumstances, including financing and acquisitions purposes. 

Recommendation   

The Board of Directors recommends a vote “FOR” this Agenda Item 4. 

P-10 

 
 
 
AGENDA ITEM 5 

Reelection of 11 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, Merrill A. “Pete” Miller, Jr., 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  six  different  nationalities 
represented in our director and executive officer group and over 55 in our global workforce. We have a presence in over 
25 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 2018 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 at the 2018 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 12, 2018. 

Nominees for Director 

MERRILL A. “PETE” MILLER, JR., age 67, U.S. citizen, has served as a director of the Company since 
2014, as Vice Chairman from 2014 to 2015 and as Chairman of the Board of Directors since 2015. Mr. Miller previously 
served  as President  and  Chief  Executive Officer of National  Oilwell Varco,  Inc.  (NYSE:  NOV),  a supplier  of  oilfield 
services and equipment to the oil and gas industry from 2001 to 2014, and as Chairman of NOV’s Board from 2002 to 
2014. Mr. Miller also served as Executive Chairman of NOW Inc., a spinoff of the distribution business of National Oilwell 
Varco, Inc. from 2014 to 2017. Before joining NOV in 1996, Mr. Miller served as President of Anadarko Drilling Company 
from 1995 to 1996. Prior to that, he spent 15 years at Helmerich & Payne International Drilling Company (NYSE: HP) in 
Tulsa, Oklahoma, serving in various senior management positions, including Vice President, U.S. Operations. Mr. Miller 
currently  is  the  chairman  of  the  Board  of  Directors  of  Ranger  Energy  Services,  Inc.  (NYSE:  RNGR)  (since  2017),  a 
provider of well service rigs and associated onshore services in the United States, and a director of Chesapeake Energy 

P-11 

Corporation (NYSE: CHK) (since 2007), one of the largest producers of natural gas, oil and natural gas liquids in the U.S., 
where he served as Lead Independent Director from 2010 to 2012. Mr. Miller is also a director of Borets International 
Limited (since 2016) and serves on the Board of Directors for the Offshore Energy Center, Petroleum Equipment Suppliers 
Association and Spindletop International. He is a member of the National Petroleum Council. Mr. Miller graduated from 
the United States Military Academy, West Point, New York in 1972 and, upon graduation, served five years in the United 
States Army. Mr. Miller received his Master’s in Business Administration from Harvard Business School in 1980. 

The  Board  of  Directors  has  concluded  that  Mr. Miller  should  remain  on  the  Board  of  Directors  and  has 
recommended that he serve an additional term. Mr. Miller has significant experience in the oilfield services industry, is 
highly knowledgeable and provides both customer and supplier perspectives to matters directly relevant to the Company. 
Mr. Miller  served  as  a  chief  executive  officer  and  thus  adds  helpful  executive  perspective  to  the  Board  of  Directors’ 
deliberations in advising the Company’s Chief Executive Officer. The Board of Directors believes that these qualities, as

AGENDA ITEM 10 

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  2018  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  2018  Annual  General  Meeting,  we  will  consider  our  shareholders’  feedback  and  the  Compensation 
Committee will evaluate whether any actions are necessary to address this feedback. 

P-21 

Recommendation 

The  Board  of  Directors  recommends  that  you  vote  “FOR”  approval  of  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 this proxy statement.

AGENDA ITEM 11 

Prospective Vote on the Maximum Compensation of the Board of Directors and the Executive 
Management Team 

11A       Ratification of the Maximum Aggregate Amount of Compensation of the Board of Directors for the Period 

Between the 2018 Annual General Meeting and the 2019 Annual General Meeting. 

Proposal of the Board of Directors 

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 period between the 2018 Annual General Meeting 
and the 2019 Annual General Meeting. 

Explanation 

As  required  by  our  Articles  of  Association  and  the  Minder  Ordinance,  the  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 
Board of Directors for the period between the 2018 Annual General Meeting and the 2019 Annual General Meeting (the 
“2018/2019 Term”). The shareholder vote is of binding nature. 

Directors’ Compensation Principles 

The general principles of the compensation for our Board of Directors are described in article 29b of our Articles 

of Association. 

We use a combination of cash and equity compensation to attract and retain qualified candidates to serve on our 
Board  of  Directors.  Our  directors’  compensation  consists  of  (1)  cash  retainers,  (2)  grants  of  restricted  share  units  and 
(3) dividend equivalents on vested and unvested restricted share units. 

Set forth below is an overview of the non-employee director compensation elements for the term of office between 
the 2016 Annual General Meeting and the 2017 Annual General Meeting (the “2016/2017 Term”), and the term of office 

P-23 

between the 2017 Annual General Meeting and the 2018 Annual General Meeting (the “2017/2018 Term”). Additionally, 
the compensation elements currently contemplated for the 2018/2019 Term are also provided:

A more detailed description of the compensation principles currently in effect for our Board of Directors can be 
found  under  “Board  Meetings  and  Committees—Director  Compensation  Strategy.”  The  actual  amounts  paid  to  each 
member of the Board of Directors for fiscal year 2017 are disclosed under “2017 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 2018/2019 Term. This amount is the maximum amount 
that  the  Company  can  pay  or  grant  to  the  members  of  the  Board  of  Directors  for  the  2018/2019  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 2016/2017 Term, and 
the shareholder-approved, maximum aggregate compensation payable to our Board of Directors for the 2017/2018 Term. 
The 2016/2017 and 2017/2018 Terms include 10 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 2018/2019 Term. This proposal is unchanged from the maximum aggregate compensation proposed 
for  the 2016/2017  Term  and  the  2017/2018 Term,  which  were  previously  approved  by  our  shareholders,  and  includes 
consideration in the 2018/2019 Term for 10 non-employee directors, one of whom will be Chairman and one of whom 
may be Vice-Chairman.

directors of Transocean Partners; each received a cash retainer and a grant of restricted share units of Transocean Partners. 

(2)     Restricted share units are granted to each non-employee director annually immediately following the Board of Directors meeting held in connection
with our Annual General Meeting. On the date of grant, the restricted share units have an aggregate value equal to the U.S. dollar figure indicated
in “2017 Director Compensation” table, and 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. 

(3)     Aggregate grant date fair value under accounting standards for recognition of share-based compensation expense for restricted share units granted

to our non-employee directors, computed in accordance with FASB ASC Topic 718. 

(4)     Aggregate target amount. 
(5)     Dividend equivalents paid or to be paid during the respective terms of office on all vested restricted share units. For an overview of our directors’
vested and unvested restricted share units, please see Note 6—Share Ownership in the Company’s statutory financial statements for fiscal year
2017. 

(6)     Mandatory employer-paid social taxes pursuant to applicable law are not included in the total amount. In 2017, employer-paid social taxes totaled 

U.S. $33,487. 

The aggregate compensation paid to date and expected to be paid to the members of the Board of Directors during 
the  2017/2018  Term  is  within  the  maximum  aggregate  amount  approved  by  shareholders  at  the 2017  Annual General 
Meeting. The actual payout and grants will be disclosed in the 2019 and 2020 Proxy Statements, respectively, and the 
Swiss Compensation Report for fiscal years 2018 and 2019, respectively. 

Recommendation 

The Board of Directors recommends that you vote “FOR” this Agenda Item 11A. 

11B 

Ratification of the Maximum Aggregate Amount of Compensation of the Executive Management Team for 
Fiscal Year 2019. 

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 2019. 

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 2019. The shareholder vote is of binding nature. 

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 Operating and Performance 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 2015-2017 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 and 
2016, the shareholder approval levels have been 86%, 81%, 92%, 80%, 87%, and 96%, 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 2017, as is explained in detail 
in Agenda Item No. 10. 

The proposed maximum aggregate amount of compensation for the Executive Management Team for fiscal year 
2019  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 2019 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 
2019. This amount is unchanged from the approved maximum aggregate amount of compensation for fiscal year 2018, 
and is the maximum amount that the Company can pay or grant to its members of the Executive Management Team for 
fiscal year 2019, 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 2018 Annual General Meeting.   

The table below shows the maximum aggregate amount of compensation that could have been paid or granted in 
the  fiscal year  2017  under  our  compensation  principles  and  plans,  the  maximum  aggregate  amount  of  compensation 
available to be paid or granted for fiscal year 2018 under our compensation principles and plans currently in effect, and 
our proposed maximum aggregate amount of compensation for fiscal year 2019. 

The  proposed  maximum  aggregate  amount  of  compensation  for  fiscal year  2019  is  based  on  our  estimated 
compensation levels and is unchanged from the maximum aggregate amount of compensation for fiscal year 2018, 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  6  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 2017. 

(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 85% 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 2019 grant 
cycle, the actual number of shares to be allocated under such long-term incentive plans will be determined in 2022 depending on 
performance achievement over a three-year performance cycle and may range between 0-200%. 

(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 2017, 
employer-paid social taxes totaled U.S. $208,015. 

Shareholder approval is based on the maximum aggregate amounts that could be payable in accordance with our 
compensation principles as set out in the 2018 Proxy Statement’s “Compensation Discussion and Analysis.” Therefore, 
actual aggregate amounts paid to our Executive Management Team members for fiscal year 2019 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 (2017: U.S. $18,130,016) than the maximum amount payable (2017: 
U.S. $29,023,000) 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  2019  Executive  Management  Team  compensation  will  be  disclosed  in  the  proxy  statement  for  our  2020 

annual general meeting and the Swiss Compensation Report for fiscal year 2019.

AGENDA ITEM 12 

Approval of Amendment to Transocean Ltd. 2015 Long-Term Incentive Plan for Additional Reserves 

Proposal of the Board of Directors 

The Board of Directors proposes that the shareholders approve an amendment to the Transocean Ltd. 2015 Long-
Term  Incentive  Plan  for  additional  reserves  in  the  aggregate  amount  of  12,000,000  shares  issuable  pursuant  to  the 
Transocean Ltd. 2015 Long-Term Incentive Plan (“2015 LTIP”), which was originally approved by shareholders on May 
15, 2015.   

Background and Purpose of the Proposal 

The use of share-based awards is a key component of our compensation program and the 2015 LTIP is designed 
to attract and retain employees of the Company and its subsidiaries, to attract and retain qualified non-employee directors 
of the Company,  to encourage the sense of proprietorship of such employees and directors and to stimulate the active 
interest of such persons in the development and financial success of the Company and its subsidiaries. These objectives 
are to be accomplished by making awards under the 2015 LTIP and thereby providing award recipients with a proprietary 
interest in the growth and performance of the Company and its subsidiaries. 

At the time of our shareholders’ approval of the 2015 LTIP, we estimated based on granting practices and the 
trading price of the Company’s shares that the 2015 LTIP would cover awards for at least three years. As of March 1, 
2018, following the 2018 annual equity grant cycle, approximately 3.25 million shares remain available under the 2015 
LTIP,  from  the  20,712,966  shares  available  for  awards  under  the  2015  LTIP,  which  includes  the  19,500,000  shares 
originally approved by shareholders on May 15, 2015, as well as unawarded shares under the Long-Term Incentive Plan 
of  Transocean  Ltd.,  as  amended  and  restated  as  of  February  12,  2009  (the  “Prior  LTIP”).  Shareholder  approval  of  an 
additional 12,000,000 shares will offer the Company the necessary flexibility to continue making share-based grants over 
the  next  three  to  four  years  in  amounts  determined  appropriate  by  the  Compensation  Committee.  This  timeline  is  an 
estimate, as future circumstances may require a change to expected equity grant practices; including the future price of our 
common stock, award levels and our hiring activity. 

As of December 31, 2017, we had the following with regard to all of our share-settled equity plans:   

Total Stock Options Outstanding 

Total Restricted Share Awards/Units Outstanding 

Total Shares Outstanding 

Weighted-Average Exercise Price of Stock Options Outstanding 

Weighted-Average Remaining Duration of Stock Options Outstanding 

Total Shares Available for Grant Under the Prior LTIP 

2,753,463 

6,421,219 

391,237,308 

$     34.98 

6.37 

9,881,169 

We believe we have demonstrated our commitment to sound equity compensation practices. Management and 
our  Board  are  cognizant  of  the  expense  attributable  to  compensatory  share  awards,  as  well  as  dilution,  and  strive  to 
maintain both at appropriate levels in order to realize the significant motivational and performance benefits that may be 
achieved from making such awards. 

As of December 31, 2017, dilution attributed to the 2015 LTIP was approximately 4.4% and would increase by 
approximately 2.8% upon approval of 12,000,000 additional reserves. The three-year average annual percentage of the 
Company’s outstanding shares issued under the Company’s various equity incentive plans or the Company’s “burn rate” 
was 1.25%, well below the Institutional Shareholder Services cap for our industry of 2.0%. We calculated our burn rate 
by (a) applying a factor of two and a half to restricted share and restricted share unit awards and a factor of one to stock 
option awards during the calendar year and (b) dividing the resulting number by the weighted average number of shares 
outstanding during such year. 

The full text of the 2015 LTIP and the proposed amendment to the 2015 LTIP are attached to this proxy statement 

as Annex B. Highlights of the 2015 LTIP include: 

P-28 

 
•  Fungible share pool. The 2015 LTIP uses a fungible share pool under which each share issued pursuant to a 
restricted  share  award  or  restricted  share  unit  (including  performance  awards)  will  reduce  the  number  of 
shares available under the 2015 LTIP by 1.68 shares, and each share issued pursuant to awards other than 
restricted share awards and restricted share units will reduce the number of shares available by 1.0 share. 

•  No liberal share counting. The 2015 LTIP prohibits the reuse of shares withheld or delivered to satisfy the 
exercise price of, or to satisfy tax withholding requirements for any awards under the 2015 LTIP. The 2015 
LTIP also prohibits “net share counting” upon the exercise of options or stock appreciation rights (or SARs) 
and the use of shares reacquired in the open market or otherwise using cash proceeds from the exercise of 
stock options.  

•  No repricing or reloading of stock options or SARs; no cash outs. The 2015 LTIP prohibits the direct or 
indirect repricing of stock options or SARs without shareholder approval and also prohibits the repurchase 
by the Company of outstanding stock options or SARs with an exercise price higher than the current fair 
market value. 

•  No discounted stock options or SARs. All stock options and SARs must have an exercise price or base price 

equal to or greater than the fair market value of the underlying shares on the date of grant. 

•  Definition of change of control. The 2015 LTIP defines “change of control” in a manner such that a change 
of control would not be deemed to occur until the actual consummation of the event that results in the change 
of control. 

•  No automatic vesting on a change of control. The terms of the 2015 LTIP do not provide for automatic single-

trigger vesting upon the occurrence of a change of control.  

•  Minimum  vesting. Awards  granted  to  employees  under  the  2015  LTIP  may  not  vest  earlier  than  the  first 
anniversary of the grant date and awards granted to directors may not vest earlier than the first to occur of 
(i) the first  anniversary of  the  grant  date or  (ii) the date  of  the  annual  general  meeting  of  the  Board next 
following the grant date.  

•  No dividend equivalents on options, SARs or unvested awards. The terms of the 2015 LTIP do not permit 
dividend equivalents to be made a part of an award of stock options or SARs and do not permit payment of 
dividend equivalents with respect to awards that are unvested. 

•  Administered by an  independent committee. The Compensation Committee, which is made up entirely of 

independent directors, has ultimate administration authority for the 2015 LTIP.   

Shares Available for Award and Share Counting 

When originally adopted, the 2015 LTIP reserved a total of 20,712,966 shares for awards, which included shares 
from the Prior LTIP that had not been granted. Subject to shareholders’ approval of the proposed amendment to the 2015 
LTIP, an additional 12,000,000 shares will be reserved for awards under the 2015 LTIP. Awards under the 2015 LTIP will 
reduce the shares available for grant under the 2015 LTIP as follows: each share issued pursuant to a restricted share award 
or restricted share unit will reduce the number of shares available under the 2015 LTIP by 1.68 shares, and each share 
issued pursuant to awards other than restricted share awards and restricted share units will reduce the number of shares 
available by 1.0 share. 

Any of the authorized shares may be used for any of the types of awards described in the 2015 LTIP. Shares 
related to performance awards that are payable solely in cash, which include performance share units to be awarded under 
the 2015 LTIP, will not be counted against the aggregate number of shares available under the 2015 LTIP. The aggregate 
number of shares underlying options and SARs and the aggregate number of shares pursuant to restricted share, restricted 
share units or other share-based awards that may be granted to any participant in any calendar year each may not exceed 
600,000 shares. In addition, the maximum amount granted to an employee participant pursuant to awards that may be 
settled in cash in any calendar year may not exceed a grant date value of $5,000,000. The maximum award value granted 
to a non-employee director in any calendar year may not exceed $1,000,000. 

P-29 

If any shares subject to an award under the 2015 LTIP or, after May 15, 2015, any shares subject to an award 
under the Prior LTIP, are forfeited, expire, are settled for cash or otherwise cancelled, then, in each case, the shares subject 
to the award may be used again for awards under the 2015 LTIP to the extent of the forfeiture, expiration, cash settlement 
or cancellation. The shares will be added back as (a) 1.68 shares for every share if the shares were subject to restricted 
share awards or restricted share units granted under the 2015 LTIP or restricted shares, restricted share units or performance 
units granted under the Prior LTIP between May 15, 2009 and May 15, 2015 and (b) as 1.0 share for every share if the 
shares were subject to awards other than restricted share awards or restricted share units granted under the 2015 LTIP and 
other than restricted shares, restricted share units or performance units granted under the Prior LTIP between May 15, 
2009 and May 15, 2015. 

The following shares will not be added to the shares authorized for grant as described above: 

(i) 

(ii) 

shares tendered by the participant or withheld by us in payment of the purchase price of an option;  

shares tendered by the participant or withheld by us to satisfy any tax withholding obligation with respect 
to an award;  

(iii) 

shares that are not issued due to net settlement of an award; and  

(iv) 

shares  reacquired  by  the  Company  on  the  open  market  or  otherwise  using  cash  proceeds  from  the 
exercise of options. 

The  2015  LTIP  provides  for  appropriate  adjustments  in  the  event  of  a  merger,  demerger,  consolidation, 
recapitalization, stock split, combination of shares, plan of exchange, share dividend or similar transaction involving the 
Company. 

Administration 

The Compensation Committee of the Board has overall authority to administer the 2015 LTIP. The Board may 

designate another committee or committees to administer the 2015 LTIP. 

Eligible Participants 

As  of  January  31,  2018,  the  Company  had  approximately  5,360  employees  (of  which  six  employees  were 

executive officers) and 10 non-employee directors who would be eligible to participate in the 2015 LTIP. 

Types of Awards 

The 2015 LTIP authorizes the issuance of the following types of awards: 

•  Nonqualified and Incentive Stock Options. Nonqualified stock options and incentive stock options may be 
granted under the 2015 LTIP. The exercise price of options may not be less than the fair market value of our 
shares on the date of grant and no option may be exercised after the expiration of ten years from the date of 
grant. The fair market value of our shares is determined by reference to the reported closing price on the 
NYSE. An option may be exercised only to the extent that the option is vested in accordance with a schedule 
determined by the Compensation Committee in its sole discretion. 

• 

Stock appreciation rights or SARs. SARs may be granted to participants under the 2015 LTIP. The exercise 
price of a SAR may not be less than the fair market value of our shares on the date of grant and no SAR may 
be  exercised  after  the  expiration  of  ten  years  from  the  date  of  grant.  The  payment  of  the  appreciation 
associated with the exercise of a SAR will be made by the Company in shares of our common stock or in 
cash as determined by the Compensation Committee. A SAR may be exercised only to the extent that the 
SAR  is  vested  in  accordance  with  a  schedule  determined  by  the  Compensation  Committee  in  its  sole 
discretion.  

•  Restricted  share  awards and  restricted  share  units. Restricted  share  awards  and  restricted  share  units,  or 
RSUs, may be granted under the 2015 LTIP. Restricted share awards and RSUs granted under the 2015 LTIP 
will vest in accordance with a schedule or achievement of certain performance or other criteria as determined 
by the Compensation Committee. Upon termination of service or employment prior to vesting, the restricted 

P-30 

shares  or  RSUs  will  be  forfeited,  unless  otherwise  determined  by  the  Compensation  Committee.  The 
Compensation Committee has the discretion to grant a holder of restricted shares the right to vote such shares 
and to receive dividends. RSUs do not entitle a holder to any of the rights of a shareholder with respect to 
the  shares;  however,  the  Compensation  Committee  has  the  discretion  to  grant  dividend  equivalents  with 
respect to the RSUs provided that no dividend equivalents may be paid with respect to an award that has not 
vested.  

•  Performance awards. Performance awards may be granted under the 2015 LTIP. Performance awards issued 
under the 2015 LTIP will become payable in accordance with the achievement of certain performance or 
other criteria as determined by the Compensation Committee, provided that a performance period may be no 
less than one year in duration. Performance measures may be based on the achievement of one or more of 
the  following:  (1) increased  revenue;  (2) net  income  measures  (including  but  not  limited  to  income  after 
capital costs and income before or after taxes); (3) share price measures (including but not limited to growth 
measures and total shareholder return); price per share; market share; earnings per share (actual or targeted 
growth); (4) earnings before interest, taxes, depreciation, and amortization (“EBITDA”); (5) economic value 
added  (or  an  equivalent  metric);  (6) market  value  added;  (7) debt  to  equity  ratio;  (8) cash  flow  measures 
(including but not limited to cash flow return on capital, cash flow return on tangible capital, net cash flow 
and  net  cash  flow  before  financing  activities,  cash  flow  value  added,  cash  flow  return  on  market 
capitalization); (9) return measures (including but not limited to return on equity, return on average assets, 
return on capital, risk-adjusted return on capital, return on investors’ capital and return on average equity); 
(10) operating measures (including operating income, funds from operations, cash from operations, after-tax 
operating  income;  sales  volumes,  production  volumes  and  production  efficiency);  (11) expense  measures 
(including but not limited to overhead cost and general and administrative expense cost control and project 
management);  (12) margins;  (13) shareholder  value;  (14) total  shareholder  return;  (15) proceeds  from 
dispositions;  and  (16) total  market  value  and  corporate  values  measures  (including  ethics  compliance, 
environmental, human resources development and safety).   

•  Cash  awards. Cash  awards  may  be  granted  under  the  2015  LTIP  and  may  be  made  subject  to  a  vesting 

schedule or other performance measures as determined by Compensation Committee. 

Non-Employee Director Awards 

The  Compensation  Committee  may  grant  awards  of  restricted  share  awards  or  restricted  share  units  to  non-

employee directors under the 2015 LTIP. 

Minimum Vesting Requirements 

The 2015 LTIP does not permit employee awards to vest earlier than the first anniversary of the grant date and 
does not permit non-employee director awards to vest earlier than the first to occur of (a) the first anniversary of the grant 
date or (b) the date of the annual general meeting of the Board next following the grant date. 

Prohibitions Related to Stock Options and SARs 

Unless the approval of shareholders is obtained first, the 2015 LTIP does not permit (a) repricing of stock options 
or SARs after the grant date, (b) accepting outstanding stock options or SARs for surrender as consideration for the grant 
of  a  new  option  or  SAR  with  a  lower  exercise  price  or  for  the  grant  of  another  award,  (c) repurchasing  from  award 
recipients any outstanding stock options or SARs that have an exercise price higher than the current fair market value of a 
share, or (d) granting any stock option or SAR that contains a "reload" feature under which additional stock options, SARs 
or other awards are granted automatically upon exercise of the original stock option or SAR. The 2015 LTIP also prohibits 
dividend equivalents with respect to stock options and SARs. 

Treatment of Awards Upon Certain Events 

Retirement, Death, Disability or Change of Control. The Committee may, in its sole discretion, accelerate the 
vesting of unvested awards or waive, eliminate or make less restrictive the restrictions or provisions governing awards or 
otherwise amend or modify awards in the case of retirement from employment or service on the Board, death, disability, 
change of control, or any other reason, except that any modification may not be materially adverse to the award recipient 

P-31 

unless the recipient has consented to the modification or the modification relates to a merger, reorganization or similar 
transaction. 

Termination and Agreement 

The 2015 LTIP may be terminated or amended by the Board. Shareholder approval is required for any amendment 
to the 2015 LTIP if (i) such approval is necessary or desirable to qualify or comply with any tax or regulatory requirement 
for which or with which the Board deems it necessary or desirable to qualify or comply; or (ii) in the opinion of counsel 
to the Company, shareholder approval is required by any federal or state laws or regulations or the rules of any stock 
exchange on which the shares may be listed. 

Transferability 

Awards are not transferable except by will or by the laws of descent and distribution. 

U.S. Federal Income Tax Consequences 

Under current federal tax law, the following are the U.S. federal income tax consequences generally arising with 
respect to restricted shares, performance shares, options and other awards granted under the 2015 LTIP. The discussion is 
not a complete analysis of all federal income tax consequences and does not cover all specific transactions which may 
occur. 

Absent the filing of a Section 83(b) election with the IRS, no income will be recognized by a participant for U.S. 
federal income tax purposes upon the grant of restricted shares, performance shares or other stock awards. Upon the vesting 
of  an  award  for  which  no  payment  was  made  by  the  participant,  the  participant  will  recognize  ordinary  income  in  an 
amount equal to the fair market value of the shares on the vesting date. Income recognized upon vesting by a participant 
who is an employee will be considered compensation subject to withholding at the time the income is recognized and, 
therefore,  the  Company  must  make  the  necessary  arrangements  with  the  participant  to  ensure  that  the  amount  of  tax 
required to be withheld is available for payment. Stock awards provide the Company with a deduction equal to the amount 
of income recognized by the participant, subject to certain deduction limitations. A participant's adjusted basis in the shares 
received through stock awards is equal to any ordinary income related to the award recognized by the participant. If a 
participant thereafter sells the shares, any amount realized over (under) the adjusted basis of the shares will constitute 
capital gain (loss) to the participant for U.S. federal income tax purposes. If a participant forfeits an award prior to its 
vesting, the participant will not recognize any ordinary income as a result of such forfeiture, and no deduction will be 
provided to the Company. 

Upon  the  grant  of  restricted  shares,  the  participant  may  file  an  election  under  Section 83(b)  of  the  Code  to 
accelerate the recognition of ordinary income to the grant date of the award. Such ordinary income is equal to the fair 
market value of the shares on the grant date (assuming no payment by the participant for the shares) and is considered 
compensation subject to withholding for employees. 

There  are no  tax  consequences  associated with  the grant or  timely  exercise  of  an  incentive  stock option. If a 
participant holds the shares acquired upon the exercise of an incentive stock option for at least one year after exercise and 
two years after the grant of the option, the participant will recognize capital gain or loss upon sale of the shares equal to 
the difference between the amount realized on the sale and the exercise price. If the shares are not held for the required 
period, the participant will recognize ordinary income upon disposition in an amount equal to the excess of the fair market 
value  of  the  shares  on  the  date  of  exercise  over  the  exercise  price,  up  to  the  amount  of  the  gain  on  disposition.  Any 
additional gain realized by the participant upon disposition will be capital gain. The excess of the fair market value of 
shares received upon the exercise of an incentive stock option over the option price for the shares is a preference item for 
purposes of the alternative minimum tax. An expense deduction by the Company in connection with the exercise of an 
incentive stock option is not allowed unless the participant recognizes ordinary income. 

Generally, no income will be recognized by a participant for U.S. federal income tax purposes upon the grant of 
a nonqualified stock option. Upon exercise of a nonqualified stock option, the participant will recognize ordinary income 
in an amount equal to the excess of the fair market value of the shares on the date of exercise over the amount of the 
exercise price. Income recognized by a participant who is an employee, upon the exercise of a nonqualified stock option, 
will be considered compensation subject to withholding at the time the income is recognized and, therefore, the Company 
must make the necessary arrangements with the participant to ensure that the amount of tax required to be withheld is 

P-32 

available for payment. Nonqualified stock options provide the Company with a deduction equal to the amount of income 
recognized  by  the  participant,  subject  to  certain  deduction  limitations.  The  adjusted  basis  of  shares  transferred  to  a 
participant pursuant to the exercise of a nonqualified stock option is the price paid for the shares plus an amount equal to 
any income recognized by the participant as a result of the exercise of the option. If a participant thereafter sells shares 
acquired upon exercise of a nonqualified stock option, any amount realized over (under) the adjusted basis of the shares 
will constitute capital gain (loss) to the participant for U.S. federal income tax purposes. 

If a participant surrenders shares which the participant already owns as payment for the exercise price of a stock 
option, the participant will not recognize gain or loss as a result of such surrender. The number of shares received upon 
exercise  of  the  option  equal  to  the  number  of  shares  surrendered  will  have  a  tax  basis  equal  to  the  tax  basis  of  the 
surrendered shares. The holding period for such shares will include the holding period for the shares surrendered. The 
remaining shares received will have a basis equal to the amount of income the participant recognizes upon receipt of such 
shares. The participant's holding period for such shares will commence on the day after such exercise. 

Generally, no income will be recognized by a participant for U.S. federal income tax purposes upon the grant of 
a SAR. Upon exercise of a SAR, the participant will recognize ordinary income in an amount equal to the excess of the 
fair market value of the shares on the date of exercise over the amount of the exercise price. Income recognized by a 
participant who is an employee, upon the exercise of a SAR, will be considered compensation subject to withholding at 
the time the income is recognized and, therefore, the Company must make the necessary arrangements with the participant 
to ensure that the amount of tax required to be withheld is available for payment. SARs provide the Company with a 
deduction  equal  to  the  amount  of  income  recognized  by  the  participant,  subject  to  certain  deduction  limitations.  The 
adjusted basis of shares transferred to a participant pursuant to the exercise of a SAR is the price paid for the shares plus 
an  amount  equal  to  any  income  recognized  by  the  participant  as  a  result  of  the  exercise  of  the  SAR.  If  a  participant 
thereafter sells shares acquired upon exercise of a SAR, any amount realized over (under) the adjusted basis of the shares 
will constitute capital gain (loss) to the participant for U.S. federal income tax purposes. 

Upon the receipt of a cash award, the participant will recognize ordinary income in an amount equal to the cash 
received. Income recognized upon the receipt of a cash award by a participant who is an employee will be considered 
compensation subject to withholding at the time the cash is received and, therefore, the Company must properly withhold 
the required tax. 

Section 162(m) limits the annual tax deduction to $1 million for compensation paid by a publicly held company 
to its chief executive officer and each of the company's three other most highly compensated named executive officers, 
unless certain performance-based requirements are met. 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 will no longer be available, subject to transition relief for certain grandfathered arrangements in effect as of 
November 2, 2017.  In addition, the covered employees will be expanded to include our chief financial officer, and once 
one of our named executive officers is considered a covered employee, the named executive officer will remain a covered 
employee  so  long  as  he  or  she  receives  compensation  from  us.  Given  the  lack  of  regulatory  guidance  to  date,  the 
Compensation Committee is not yet able to determine the full impact of the 2017 Tax Act changes to Section 162(m) on 
the Company and our compensation programs, including the 2015 LTIP. 

Code  Section  409A  generally  provides  that  any  deferred  compensation  arrangement  must  satisfy  specific 
requirements,  both  in  operation  and  in  form,  regarding  (1) the  timing  of  payment,  (2) the  election  of  deferrals,  and 
(3) restrictions on the acceleration of payment. Failure to comply with Code Section 409A may result in the early taxation 
(plus interest) to the participant of deferred compensation and the imposition of a 20% penalty on the participant on such 
deferred amounts included in the participant's income. The Company intends to structure awards under the 2015 LTIP in 
a manner that is designed to be exempt from or comply with Code Section 409A. 

Recommendation 

The Board of Directors recommends you vote “FOR” this Agenda Item 12. 

P-33 

 
 
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 committee charters also require, among other things, that the committees and the Board of Directors annually evaluate 
their own performance. 

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. 

Our  current  governance  documents  may  be  found  on  our  website  at:  www.deepwater.com  by  selecting  the 

Governance page in the Investors section dropdown. Among the information you can find there is the following:

•  Our Tax Principles Statement.   

P-34 

Information contained on our website is not part of this proxy statement.   

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 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  2017,  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. 

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. 

P-35 

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. Additionally, from 2014 to 
2016, Mr. Barker served as a director, and from July 2015 until December 2016, as chairman of the board of 
directors,  of  Transocean  Partners,  formerly  a  publicly-held  subsidiary  of  Transocean  Ltd.  to  which  we 
provided  operating,  support  and  administrative  services,  in  addition  to  being  the  majority  unitholder. 
Transocean  Partners  merged  into  a  subsidiary  of  the  Company  in  December  2016  and  is  now  indirectly 
wholly-owned by the Company. 

•  Mr. Barker’s son is 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 is employed by PwC, his son does not, directly or indirectly, 
provide any services to the Company or any of its affiliates, and his son works within a division of PwC that 
does not provide any services to the Company or any of its affiliates. Moreover, Mr. Barker’s son is not a 
partner or principal of PwC, but is instead one of more than 200,000 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;  and  Mr. 
Muller’s son worked through July 2017 as an associate at Munger, Tolles & Olson, a law firm that provided 
and may in the future provide legal services 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 2013 to 2015, Mr. Merksamer served as a non-executive director of Talisman Energy, from which we 
received revenues for performing services, and, from 2014 to 2017, Mr. Merksamer served as a director of 
Hertz Global Holdings, Inc., the subsidiaries of which provide the Company with car rental services. Since 
May 2016, Mr. Merksamer has served as non-executive director of American International Group, Inc., a 
company  that provides  insurance-related  services  to  the  Company.  Mr. Merksamer  was  a  member  of  the 
board of directors of Transocean Partners from 2014 until 2016. 

•  Since 2014, Mr. Intrieri has served as a director of Hertz Global Holdings, Inc. 

•  From 2001 to 2014, Mr. Miller served as President & Chief Executive Officer of National Oilwell Varco, 
Inc., from which the Company regularly purchases drilling equipment and services, and from 2014 to 2017, 
Mr. Miller served as the executive chairman of NOW Inc., from which the Company regularly purchases 
drilling equipment and services. 

•  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 

P-36 

possess voting rights with respect to approximately 13.68% of the Company’s outstanding shares as of March 
12, 2018. 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 2017. During 2018, 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 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; and 

a reputation, both personal and professional, consistent with our 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 

P-37 

of  Directors  candidates,  interviewing  those  candidates  and  conducting  investigations  relative  to  their  background  and 
qualifications. 

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 

P-38 

meetings. Each calendar year, the Compensation Committee reviews the compensation paid to our 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 2017, 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 2017, 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 completed earlier this year, Mr. Mohn acquired beneficial 
ownership of $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 

P-39 

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 stockholders. 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 2018 Annual General 

Meeting. At the 2017 Annual General Meeting, all directors then serving on the Board of Directors were in attendance. 

Board Meetings and Committees 

During  2017,  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 at least 80% 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. 

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 incentives plans, Performance Award and Cash Bonus Plan, Deferred 
Compensation Plan, and any other compensation plans or arrangements providing for benefits primarily to 

P-40 

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 incentives 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 
incentives 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. 
Martin  B.  McNamara  was  also  a  member  of  the  Compensation  Committee  prior  to  his  retirement  from  the  Board  of 
Directors on January 30, 2018. The Compensation Committee met four times during 2017. 

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 

P-41 

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. Ms. Chang also served on the Finance Committee in 2017 and continued this service until February 8, 2018, 
when she accepted a new assignment on the Corporate Governance Committee. The Finance Committee met four times 
during 2017. 

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 
functions  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, Mr. Deaton and Ms. 
Chang, who became a member of the Committee on February 8, 2018. Mr. McNamara was also a member and the chair 
of the Corporate Governance Committee prior to his retirement from the Board of Directors on January 30, 2018. The 
Corporate Governance Committee met four times during 2017. 

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. The Health, Safety 
and  Environment  Committee  in  2013  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 Health, Safety and Environment Committee has required the Company to provide, and reviews, regular 
reports regarding compliance with all aspects of the Consent Decree. 

The current members of the Health, Safety and Environment Committee are Mr. Deaton, Chairman, and Messrs. 
Merksamer, Muller and Tan. Mr. Mohn also joined the Health, Safety and Environment Committee on February 8, 2018. 
The Health, Safety and Environment Committee met four times during 2017. 

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; 

P-42 

• 

• 

• 

• 

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, Mr. Curado and Mr. Mohn, 

who joined the Audit Committee on February 8, 2018. The Audit Committee met eight times during 2017. 

The Board of Directors has reviewed the criteria set by the 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 each of the current members of the Audit Committee qualifies under NYSE rules as 
having accounting or related financial management expertise. 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. 

In  addition  to  Mr.  Barker’s  membership  on  the  Audit  Committee,  he  also  serves  on  the  audit  committees  of 
Berkley  Group  Holdings  plc  and  Aviva  plc.  Pursuant  to  NYSE  rules,  the  Board  of  Directors  has  determined  that  Mr. 
Barker’s  service  on  the  audit  committees  of  such  companies  would  not  impair  his  ability  to  effectively  serve  on  the 
Company’s Audit Committee. 

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. 

P-43 

 
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 2017, 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, Safety and 

Environment Committee

  10,000  
 210,000  
 325,000  

(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. 

2017 Director Compensation 

In 2017, each non-employee member of the Board of Directors received the compensation described above. 

At the Board of Directors meeting held immediately after the 2017 Annual General Meeting of our shareholders, 
the Board of Directors granted 19,301 restricted share units to each non-employee director (other than the Chairman) and 
29,871 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. $10.88 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.

AUDIT COMMITTEE REPORT 

The Audit Committee, consisting of four independent directors, operates under the Audit Committee Charter as 

adopted by the Board, in overseeing: 

(i) 

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

(ii) 

compliance with legal and regulatory requirements;   

(iii) 

the independence, qualifications and performance of the Company’s independent registered accountants, 
Ernst & Young LLP (“EY”); and   

(iv) 

the performance of the internal audit function.   

The Committee complied in 2017 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 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; 

•  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 Vice President, Internal 

Audit, 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 conduct; and 

•  Recommended to the Company’s Board of Directors that the Company’s audited financial statements for 
the year ended December 31, 2017, 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; 

•  Length of service, which began in 1999; 

P-46 

•  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 Vice 
President, Internal Audit and EY. The Committee met eight times in 2017 with regular executive sessions with EY and 
management, including the Vice President, Internal Audit and the Chief Compliance Officer.

2017 Business Overview 

Transocean is a leading international provider of offshore contract drilling services for oil and gas wells. The 
Company specializes in technically demanding sectors of the global offshore drilling business. Transocean operates one 
of the most versatile high-specification drilling fleets in the world, with a particular focus on ultra-deepwater and harsh 
environment drilling services. 

Although we remain in a downturn for the drilling sector, we delivered strong business results in 2017, through 
financial discipline and efficient operations, while maintaining a constant focus on the safety of our workforce and our 
environment. The business highlights below demonstrate the Company’s commitment to near-term performance, while 
preparing for the ultimate recovery in this market. 

As of February 19, 2018, Transocean owns, or has partial ownership interests in, and operates a fleet of 47 mobile 
offshore drilling units consisting of 27 ultra-deepwater floaters, 12 harsh environment semisubmersibles, two deepwater 
semisubmersibles and six midwater semisubmersibles. In addition, the Company has two ultra-deepwater drillships under 
construction. The Company also operates two high-specification jackups that were under drilling contracts when the rigs 
were sold, and the Company will continue to operate these jackups until completion or novation of the drilling contracts. 

Over  the  past  six  months,  we  added  two  new  contract-backed,  ultra-deepwater  drillships  to  our  fleet:  the 
Deepwater Pontus and the Deepwater Poseidon. Both drillships have 10-year contracts with Shell in the U.S. Gulf of 
Mexico, and represent some of the most technically capable rigs in the world. Additionally, in 2017, we agreed with Jurong 
Shipyard  to  enhance  our  two  remaining  newbuild  drillships  that  are  under  construction  by  increasing  the  hook  load 
capacities  to  an  industry-best  three  million  pounds.  We  also  opportunistically  upgraded  the  ultra-deepwater  drillship 
Discoverer India by adding a second annular to the BOP stack, converting the rig to DP-3 station-keeping from DP-2 and 
making the rig Managed Pressure Drilling capable. 

In 2017, we announced an agreement to acquire Songa Offshore SE, adding seven semisubmersibles to our fleet 
including four high-specification, harsh environment CAT-D rigs – the Equinox, Endurance, Encourage, and Enabler – 
on long-term contracts with Statoil. This transaction closed on January 30, 2018. 

Further,  we  reactivated  four  floaters,  all  associated  with  new  contracts,  from  either  a  warm  or  cold-stacked 
condition. We also strengthened our fleet by announcing the retirement of nine older, less-competitive assets, including 
five ultra-deepwater rigs, which were unlikely to be marketable going forward. 

Despite challenging market dynamics, we executed many new contracts in 2017, adding U.S. $873 million in 
contract backlog, an increase of approximately 70% from 2016. We converted a large percentage of our 2017 backlog to 
cash,  with  strong  operational  performance,  as  measured  by  our  Uptime  rate  of  96.8%.  As  of  February  19,  2018,  our 
combined Company backlog, including Songa Offshore, totaled U.S. $12.8 billion, more than twice the nearest competitor. 

In 2017, we continued to drive operational excellence through improvements in safety and drilling efficiency. 
We delivered the lowest Total Recordable Incident Rate in the Company’s history, and achieved 11 consecutive months 
in 2017 without a Lost Time Incident. When added to 2016’s performance, we achieved a Company record 20 consecutive 
months without a Lost Time Incident across our global fleet. 

We executed additional supplier contracts with Original Equipment Manufacturers (“OEM”). These new OEM 
agreements cover some of the most critical equipment on our rigs and support our goals of reducing operating costs and, 
more importantly, continuing to improve equipment reliability. 

We  continued  to  strengthen  our  liquidity  and  financial  position,  executing  multiple  financing  transactions.  In 
2017, we issued approximately U.S. $1.2 billion of debt maturing in 2022 and 2026, while retiring U.S. $1.8 billion of 
debt with maturities between 2017 and 2020. Additionally, we removed approximately $1 billion of shipyard obligations 
with the sale of our five uncontracted jackups under construction. These actions, along with our outstanding operational 
performance, positioned us with U.S. $3.0 billion of cash, cash equivalents and short-term investments as of December 31, 

P-52 

2017, and a U.S. $3 billion undrawn, unsecured revolving credit facility, providing significant liquidity during this industry 
downturn and preserving strategic optionality and shareholder value. 

Given Transocean’s long history as an industry-leading provider of offshore drilling services, we believe that we 
have the experience and financial discipline necessary to effectively manage our business throughout the cycles and deliver 
long-term value to our shareholders. With better visibility of improving market fundamentals, we continue to take the 
necessary actions to maintain our position as well as strategically position Transocean to benefit from the recovery ahead.

Executive Compensation Philosophy, Strategy and Design 

The primary goal of our compensation program is to align pay with performance. The program is also designed 
to  attract,  motivate  and  retain  superior  executive  talent  in  the  geographic  locations  necessary  to  support  our  global 
operations. We accomplish these goals by providing our executives with a competitive compensation package that rewards 
performance against specific, identified financial, strategic and operational goals that the Committee believes are critical 
to the Company’s long-term success and the achievement of sustainable long-term total returns to our shareholders. 

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

positioning elements of total direct compensation, in the aggregate for our executive team, at 
approximately the median of our peer companies; 

• 
• 

aligning annual incentive compensation with financial and strategic objectives; and 

rewarding absolute share price appreciation and relative performance in TSR through long-term equity 
incentive awards. 

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 

P-53 

 
shareholder  value  without  excessive  risk-taking.  We  believe  the  approach  achieves  our  objective  of  aligning  pay  and 
performance.

Relationship Between Target and Realizable Pay   

Our compensation philosophy features the alignment of the interests of our Executive Officers with those of our 
shareholders by basing the majority of compensation on achieving desired performance outcomes. Accordingly, the actual 
total compensation values received by our Executive Officers, in recent years, have ranged from below to above targeted 
and competitive market levels. Below-target results have been driven by the lack of appreciation in the Company’s share 
price and below-target total shareholder return relative to our peers, whereas more recent above-target results reflect our 
disciplined approach to the market downturn and our recent outperformance of competitors in the offshore drilling sector. 

The Summary Compensation Table reflects the grant-date fair value for share awards, as required. However, we 
believe that realizable pay provides a better picture of the amounts actually earned. In particular, we note there have been 
no payouts under our performance-based unit program over six of the last seven performance cycles, and the majority of 
outstanding stock options are currently underwater. The more recent, in-process long-term performance cycles, however, 
reflect our superior performance relative to our offshore drilling peers, although these performance cycles remain at risk 
until their conclusion.

2017 Compensation Program Overview 

The  Company  continued  to  reinforce  the  alignment  between  pay  and  performance  with  our  executive 

compensation programs and compensation award levels for 2017. 

In recognition of the industry downturn, the Compensation Committee of the Board (the “Committee”) 

carefully considered appropriate 2017 target compensation opportunities for our Named Executive Officers. Working 
closely with its independent compensation consultant, the following executive compensation actions were implemented 
for our Named Executive Officers: 

•    Freeze on base salaries for 2017, marking a three-year freeze on base salary; 

•    Freeze on target annual cash bonus opportunities for 2017, marking a three-year freeze on annual target 

bonus opportunities; 

•    Cap on performance share payouts, including the 2017 - 2019 performance period, in the event of negative 

absolute total shareholder return (TSR) performance; 

•    Abolished all executive perquisites, including financial planning, annual physicals and club memberships, 

effective January 1, 2017; and 

•    With the relocation of one of our Named Executive Officers to the United States, no expatriate benefits are 

being paid to our Named Executive Officers. 

These compensation actions reflect the industry downturn and our focus on good governance, while maintaining 

prudently designed, competitive compensation packages for our Named Executive Officers. 

Executive Compensation Setting 

We believe that our executive compensation program must be regularly reviewed 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. 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; 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 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. 

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, 
each element of their total direct compensation is compared against published and publicly available compensation data. 

P-56 

 
 
The Compensation Peer Group for 2017 comprised the following companies: 

•  Anadarko Petroleum Corporation 
•  Apache Corporation 
•  Baker Hughes Incorporated 
•  Canadian Natural Resources Limited 
•  Chesapeake Energy Corporation 
•  Devon Energy Corporation 

•  Diamond Offshore Drilling, Inc. 
•  Encana Corporation 
•  Ensco plc 
•  EOG Resources, Inc. 
•  Halliburton Company 
•  Marathon Oil Corporation 
•  Nabors Industries Ltd. 

•  National Oilwell Varco, Inc. 
•  Noble Corporation plc 
•  Noble Energy, Inc. 
•  Petrofac Limited 
•  Seadrill Limited 
•  TechnipFMC plc 
•  Weatherford International Ltd. 

Considering  the  current  industry  downturn,  and  in  consultation  with  the  Committee’s  external  compensation 
consultant, the 2018 compensation peer group has been modified. Our peer group review considered revenue size and 
market  capitalization,  both  industry  standard  measures  in  developing  compensation  peer  groups,  to  ensure  continued 
alignment. Four larger revenue-sized companies including Baker Hughes, a GE company, Canadian Natural Resources, 
EOG Resources and Halliburton Company have been removed from the 2018 compensation peer group. Three companies 
more comparable to the Company in revenue size, including Hess Corporation, McDermott International and Murphy Oil 
Corporation, have been added to the compensation peer group. The net effect of these changes to the 2018 peer group 
composition reduces the average revenue size and market capitalization, thereby creating enhanced alignment with the 
Company’s current scope.   

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 short-term and long-term incentive 
compensation levels. 

Performance Peer Group 

The Committee establishes the Performance Peer Group used to evaluate the Company’s total shareholder return 
relative  to  that  of  companies  considered  to  be  direct  business  competitors  and  competitors  for  investment  capital. 
Beginning in 2016, the Committee refined the Performance Peer Group to focus on drillers to better align with our strategic 
business objectives, and we maintained this focus in 2017. 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 offshore drilling operations. The Performance Peer Group for 2017 
consists of: 

•  Atwood Oceanics, Inc. 
•  Diamond Offshore Drilling, Inc. 
•  Ensco plc 
•  Noble Corporation plc 
•  Ocean Rig UDW Inc. 

•  Pacific Drilling S.A. 
•  Rowan Companies Inc. 
•  Seadrill Limited 
•  Subsea 7 SA 

We will continue to assess the composition of the Performance Peer Group for 2018 and beyond with focus on 

the impact of the current industry downturn and resulting consolidation.

In assessing the reasonableness of the total direct compensation of the Named Executive Officers, particularly 
the compensation of our Chief Executive Officer, the Committee considered the amount and mix of compensation provided 
as  a  direct  link  to  creating  sustainable  long-term  shareholder  value,  achieving  our  vision  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 based on a promotion or other change in job responsibility. Each base salary is also 
reviewed by the Committee annually thereafter, both individually and, for internal pay equity purposes, relative to other 
Executive Officers. Base salary adjustments are made to reflect our desired position in the competitive market. 

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 from our Compensation Peer Group and other survey data, 
job  responsibilities,  individual  performance,  and  expected  future  contributions  of  each  Named  Executive  Officer.  The 
Committee also considers input from its compensation consultant within the framework of the Company’s compensation 
philosophy and objectives. 

In  February  2017,  the  Committee,  in  consideration  of  the  industry  downturn,  and  with  consultation  from  its 
external  compensation  consultant,  elected  to  freeze  base  salaries  for  Named  Executive  Officers,  resulting  in  no  2017 
increases over the 2016 base salaries. Further, salaries were also frozen in 2016 at the 2015 levels. As a result, there have 
been no increases to base salaries for our Named Executive Officers since 2015. 

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

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 2017, each Named Executive Officer had a potential payout range of 0% to 200% of 
his  individual  target  award  opportunity.  The  Committee  established  a  2017  target  bonus  opportunity  for  each  of  the 
following Named Executive Officers at the same target opportunity as established for 2016 and 2015. The 2017 target 
bonus opportunity for each Named Executive Officer, expressed as a percentage of base salary, is as follows:

2017 Bonus Structure 

The annual cash bonus structure is designed with a focus on 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. During the industry downturn, driven largely by low commodity 
pricing  beyond  the  Company’s  control,  this  annual  bonus  structure  is  designed  to  focus  on  those  areas  where  we  can 
differentiate ourselves from our competitors and be well-positioned to outperform the competition in the market recovery. 

The design of each measure, relative weighting, and construction of our threshold-target-maximum payout range, 
incorporate the Company’s 2017 business plan, our 2016 performance results and a focus on continuous improvement. 
The following chart compares the 2017 bonus structure measures and relative weightings compared to the 2016 bonus 
plan  structure.  This  2017  bonus  structure  further  sharpens  the  focus  on  personnel  safety  as  measured  through  Total 
Recordable Incident Rate and increases the relative weight applied to key financial results as measured through EBITDA. 
Each of the 2017 bonus plan 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.” Encouraged by the continuous improvement demonstrated in the Dropped Object Potential Severity rate and 
Operational Integrity performance during 2016, the safety component of the 2017 bonus structure has evolved from the 
three  safety  measures  found  in  the  2016  bonus  plan  to  a  single  measure  focused  on  Total  Recordable  Incident  Rate 
(“TRIR”). However, to maintain focus on Operational Integrity, the 2017 TRIR measure includes a formulaic calibration 
wherein the TRIR year-end result is reduced by 25% for any Tier 1 Operational Integrity event (see definition below).     

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. 

The Committee approved a TRIR target for 2017 of 0.39. In setting this target, the Committee received input 
from the Board’s Health, Safety and Environment (HSE) Committee, comprised of fellow 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 Outcome to Target 
Maximum = 0.33 
Target = 0.39 
Minimum = 0.44 

Bonus Payout 
200%
100%
0%

Any  TRIR outcome  representing  a result of  0.44 or greater would result in  a 0%  bonus  payout for  the  TRIR 
measure. TRIR results of 0.33 or less would result in a payout of 200% for the TRIR measure. As noted above, the year-

P-60 

 
 
 
 
 
 
     
  
 
 
 
 
 
 
 
end  TRIR  payout  would  be  reduced  by  25%  for  any  Tier  1  Operational  Integrity  event  experienced  during  the  year.   
Further,  the  Committee  evaluates  whether  to  use  negative  discretion  in  response  to  unforeseen,  extraordinary 
circumstances in considering overall bonus results. 

In setting the 2017 TRIR threshold-target-maximum values, the Committee considered the following: 

1.  Two successive years, 2015 and 2016, represented the best TRIR results in the Company’s history (2015 

TRIR was 0.42, followed by 0.34 in 2016).   

2.  As with any continuous improvement initiative, the law of diminishing marginal productivity increasingly 

challenges improvement in safety results as the Company aspires to be an incident-free workplace. 

3.  Consideration of anticipated increased rig activations in 2017, accompanied by increased hiring and the need 
to train these new hires in the Company’s safety programs and processes.    The Committee recognized this 
increased activity would challenge the Company’s ability to maintain our record setting level of continuous 
safety performance improvement. 

With consideration given to these factors, the Committee approved the 2017 TRIR target at 0.39, approximating 
the average of the Company’s outstanding trailing two-year results noted above. The Committee considered this to be an 
aggressive  target  in  light  of  the  anticipated  increase  in  rig  activity,  increased  hiring  and  necessary  safety  training 
requirements. 

In setting the threshold and maximum values, the Committee applied a 15% range above and below the target of 
0.39. This range created a minimum, or entry point, of 0.44 demonstrating continuous improvement over the 2016 range 
minimum. This stretch resulted in a maximum value of 0.33 representing continuous improvement compared to the 2016 
range maximum and an enhancement over the 2016 actual TRIR result of 0.34.     

Further, the Committee recognized the impact of Operational Integrity on personnel safety. 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: 

(cid:121)  Fire, explosion, release of a hazardous substance with serious injury or fatality 

(cid:121)  Major structural damage 

(cid:121)  Serious injuries/fatalities 

(cid:121)  Uncontrolled release of hazardous fluids 

Consistent  with  our  2016  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.

Our TRIR outcome for 2017 was 0.18, exceeding maximum performance as compared to target and representing 
the best formulaic result in the Company’s history. This result is outstanding, particularly considering the Company hired 
approximately 1,300 offshore personnel during 2017, which brought with it the challenge of training each new employee 
on the Company’s safety culture.

Committee’s discretion as described below in the section titled Actual Bonus Plan Compensation for 2017. 

Financial Performance 

Developing Our EBITDA Target   

For  the  2017  bonus  plan,  the  Committee  determined  the  financial  metric  Earnings  Before  Interest,  Taxes, 
Depreciation  and  Amortization (“EBITDA”),  a  commonly  accepted  measure  of  financial  performance,  to  be  the  most 
appropriate measure to align with the Company’s financial objectives. EBITDA was weighted at 60% of the total 2017 
annual bonus plan  opportunity.  The use of  EBITDA  is  consistent with the 2016 bonus  plan, but  refined  to reflect our 
increased weighting applied to financial performance and an updated range (i.e., Threshold – Target – Maximum) that was 
consistent with our 2017 business plan. Attached as Appendix A to this proxy statement is a reconciliation of EBITDA, a 
non-GAAP financial measure, to net income, the most directly comparable GAAP financial measure. 

We  believe  EBITDA  represents  a  holistic  view  of  the  Company’s  financial  performance  in  current  market 
conditions. The measure reflects the complete revenue and cost cycle in our business. EBITDA is an objective performance 
measure commonly used among our drilling company peers and is a financial indicator transparent and familiar to our 
shareholders. 

In establishing the 2017 bonus plan EBITDA target and range, the Committee considered the Company’s 2017 
financial  plan.  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 2017 EBITDA target was set below the 2016 
actual financial result, the target reflected the reality of the continuing industry downturn and related financial challenges.

Measuring EBITDA Results   

2017 EBITDA results were pressured given the challenging industry environment, driven mainly by continued 
weak demand for rigs and declining contract dayrates. However, a strong focus on cost management, including stacking 
costs,  combined with outstanding  revenue  efficiency for deployed  rigs  and  effective  contract  management,  resulted  in 
actual EBITDA results exceeding the target for this measure.

Operational Performance 

Developing Our UPTIME Target 

In 2016, Uptime was identified as the operational performance measure that would best align with our customers’ 
interests, and we elected to maintain this measure for 2017. This measure represented 20% of the 2017 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, there is no standard industry definition or reporting 
structure  for  it.  As  a  result,  the  Company  has  developed  its  own  definition,  and  that  definition  recognizes  the  key 
impediments to Uptime: equipment failures and human performance errors. 

Uptime is measured as operating hours, minus downtime, expressed as a percentage. Operating hours are defined 
as the number of hours a rig is engaged in 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 196,000 hours of operation in 2017). 

The Committee approved the following Uptime target for 2017: 

Uptime Target 
Threshold 
Target 
Maximum 

      Achievement 

94.0%  
95.5%  
97.0%  

In setting the 2017 Uptime target, the Committee considered the Company’s outlook for 2017, which featured: 
(i) two newbuilds commencing operations; (ii) five idle rigs returning to activity; (iii) the need to hire new personnel to 
staff the newbuilds and reactivations; and (iv) shorter contract durations, resulting in more rig mobilizations. These factors 
led the Committee to conclude that the risk of equipment failure and human performance errors – i.e., the two determinants 
of downtime – were elevated for 2017, compared to 2016. Nonetheless, the Committee did not feel comfortable lowering 

P-63 

 
 
 
 
 
 
the threshold-target-maximum range it established in 2016. Instead, it elected to maintain the 2016 range, recognizing that 
achieving the target would be difficult and, thus, would be consistent with its desire to require continuous improvement. 

Measuring Uptime Results   

Based  on  this  high  level  of  operational  efficiency,  we  achieved  96.8%  Uptime  performance  in  2017.  This 
incremental 1.3% above target performance, equates to approximately 2,550 hours, or 106.3 days, of additional operational 
productivity across the fleet, resulting in greater customer satisfaction and higher earnings.

Actual Bonus Plan Compensation for 2017 

Based on the performance measures described above and using the pre-determined weightings assigned to each 
measure by the Committee, the formulaic bonus outcome for each of our Named Executive Officers was 158% of the 
targeted bonus opportunity under the Performance Award and Cash Bonus Plan for 2017. The components of this total 
bonus payout under the Cash Bonus Plan for 2017 are as follows:

A strict application of the Cash Bonus Plan for 2017 would have resulted in a payout of 158% of the targeted 
bonus opportunity for each of our Named Executive Officers. However, the Committee remains mindful of its authority 
to exercise discretion to avoid outcomes that are inconsistent with the purposes of the Plan. These outcomes can be caused 
by unforeseen, extraordinary circumstances that arise during the year. One such circumstance arose in December 2017, 
when a personnel safety incident occurred on a rig operating in the U.S. Gulf of Mexico. While the incident is already 
included in the TRIR calculation for 2017, the Committee evaluated the incident qualitatively, with input from the Board’s 
HSE Committee. This cross-functional engagement led the Committee to conclude that the incident justified a reduction 
in  the  final  actual  bonus  outcome  for  each  Named  Executive  Officer  from  158%  to  138%.  This  result  reiterates  our 
unwavering commitment to working toward a “zero incident” safety culture. 

While the bonus result of 138% of target falls well below the 2016 bonus result of 166% of target, the annual 
results of the last two years demonstrate a strong commitment to operational, financial and safety performance during the 
prolonged and challenging industry downturn.

Long-Term Incentives 

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

To provide an appropriate balance of incentives tied to performance, three types of long-term equity instruments 
were used in 2017: Performance Units, Restricted Share Units and Non-Qualified Stock Options. The weighting of each 
instrument in our LTI program was as follows: 

Long-Term Incentive Pay Mix

Performance Share Units:  50%

Restricted Share Units:  25%

Stock Options:   25%

This LTI mix is designed to ensure that a minimum of 50% of the total weighting is applied to the Performance 
Units.  Restricted  Share  Units  are  included  in  the  incentive  mix  to  reinforce  a  direct  relationship  to  the  shareholder 
experience. Stock Options only deliver value to the executive when the Company’s share price exceeds the strike price on 
the option. All three equity instruments are also designed to be retentive in nature through multi-year performance and 
vesting periods. 

The following LTI awards were delivered to our Named Executive Officers in 2017 and 2016.

Increased  2017  equity  grant  values,  relative  to  2016  grant  values,  were  based  on  the  Committee’s  review  of 
relevant market data, the performance of each Executive Officer and the need for retention of key executive talent. The 
forms of equity awards made to our Named Executive Officers are discussed in greater detail below. 

Performance Share Units (PSU) 

The target value of the 2017 PSU grants to each of the Named Executive Officers was approximately 50% of 

each officer’s total 2017 LTI award target value. 

Each PSU represents one share and is earned based on performance over a three-year cycle from January 1, 2017 
through December 31, 2019. 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  constructing  this  performance  equity  plan,  the  Committee  considered  the  value  of  including  an  absolute 
financial measure; however, after a thorough review of market conditions and the substantial challenges in setting absolute 
financial measures as long-term incentive goals, the Committee concluded that a single measure of relative TSR within 
the 2017  Performance  Peer Group  offered  the best shareholder  alignment  and  best  supported  the  Company’s  strategic 
objective of becoming the undisputed leader in offshore drilling. 

P-65 

 
     
     
 
 
 
 
 
 
 
 
 
 
 
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%. We set the cap at this level 
to ensure that management does not benefit disproportionately from shareholder returns that are more than marginally 
negative. 

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

ranking of TSR performance:

Upon completion of the 2017 - 2019 PSU performance cycle, the Committee will determine final payout levels, 
and  PSUs  will  be  distributed  to  the  Named  Executive  Officer,  along  with  a  cash  payment  equal  to  any  dividends  or 
equivalents accrued during the performance cycle for earned and vested shares. 

Restricted Share Units (RSU) 

The target value of the 2017 RSU grants to each of the Named Executive Officers was approximately 25% of 

each officer’s total 2017 LTI award target value. 

Time-vested RSUs were granted to all Named Executive Officers as part of the 2017 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 2017 NQSO grants to each of the Named Executive Officers was approximately 25% of 

each officer’s total 2017 LTI award target value. 

Time-vested NQSOs were granted to each Named Executive Officers as part of the 2017 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 2017 

In  2018,  the  Committee  evaluated  the  Company’s  performance  for  the  three-year  performance  period  from 
January 1, 2015 through December 31, 2017, and determined the Company’s performance to be 158.3% of target. This 
result  represents  only  the  second  payout  in  the  last  eight  performance  cycles  for  the  Company,  with  the  other  payout 
achieved in 2017 for the 2014 – 2016 performance cycle. 

This performance plan consisted of two measures, equally weighted at 50% of the total award opportunity. The 
two measures included relative TSR as measured against a performance peer group, and Return on Capital Employed 
(ROCE) during the first year of the three-year performance cycle. Final measurement for this performance cycle included 
ROCE results at maximum performance. Actual ROCE financial results are not disclosed due to the proprietary nature of 
this  information  in  establishing  the  Company’s  competitive  position  in  the  market.  With  respect  to  relative  TSR,  the 
Company  ranked  5  of  12  against  performance  peer  companies,  resulting  in  performance  slightly  above  target  for  this 
measure. The two measures combined resulted in the 158.3% of target performance outcome. 

However,  when  considering  the  Company’s  share  price  decline  during  the  2015  -  2017  period,  the  158.3% 
achievement level translates to approximately 98% of target in realizable value on the date the Committee approved the 

P-66 

 
 
 
     
 
 
 
 
 
 
 
 
 
 
 
payouts compared to the expected target value at grant. Considering the value of RSUs and NQSOs are also directly related 
to  share  price,  the  realizable  value  delivered  through  the  performance  plan,  combined  with  the  other  equity  awards, 
reinforces the designed linkage between the executive’s delivered compensation and changes in share value. 

Beginning with the 2016 three-year performance plan, and replicated again in the 2017 three-year performance 
plan, the Company has removed ROCE from the plan design and created a single relative TSR measure for enhanced 
shareholder alignment. 

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 employment agreements. 

Expatriate Benefits 

For our Named Executive Officers 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 
were designed to help defray the significant expense associated with expatriation. Beginning in 2014, the Named Executive 
Officers ceased to be eligible for tax protection or tax equalization on these expatriate benefits. At the beginning of 2017, 
Mr. Stobart was the only Named Executive Officer receiving the above-mentioned expatriate benefits. In May 2017, Mr. 
Stobart repatriated to the United States, at which time all expatriate benefits ceased. As a result, the company currently 
has no Named Executive Officers receiving the above-mentioned expatriate benefits. 

The types and values of these expatriate benefits received in 2017 by Mr. Stobart are included in the Summary 

Compensation Table under “All Other Compensation” and described in the notes to that table. 

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 plans. 

Perquisites 

The Committee elected to eliminate all executive perquisites for our Named Executive Officers, effective January 

1, 2017. 

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  long-term  incentive  awards  under  certain  termination  provisions  as 

P-67 

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 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,  2017,  are  described  under  “Executive 
Compensation-Potential Payments Upon Termination or Change in Control.” 

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  benefits  policy.  Pursuant  to  their  employment  agreements, 
members  of  the  Executive  Management  Team  must  receive  at  least  twelve  months’  notice  prior  to  a  termination  of 
employment without cause. 

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  the 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. 

Compensation Committee 

The  Committee,  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, is responsible for overseeing our executive compensation and 
long-term incentive programs. Specifically, the Committee is responsible for: 

(cid:121)

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; 

P-68 

(cid:121) 

(cid:121) 

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 

(cid:121) 

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

During  2017  the  Compensation  Committee  consisted  of  four  directors:  Tan  Ek  Kia  (Chairman),  Frederico  F. 
Curado, Vincent J. Intrieri and Martin B. McNamara. Mr. McNamara retired from the Board effective January 30, 2018. 

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 2017. 

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 2017. In May 2017, the Committee assessed whether the work of Pay Governance for 
the Committee during 2017 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 Exchange Act. The Committee concluded that no conflict of interest 
was raised that would prevent Pay Governance from independently representing 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. 

P-69 

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 Performance Award and Cash 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. 

Additional Executive Compensation Information 

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. 

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 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 
Executive Vice President 
Senior Vice President 
Vice President 

6x base pay 
3x base pay 
2x base pay 
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. 

No Hedging of Company Shares 

We have a policy that prohibits any of our Executive Officers and directors from holding derivative instruments 
tied to our shares, other than derivative instruments that may be granted by us (e.g., stock options). Our Executive Officers 
and directors are prohibited from hedging, engaging in short sales and holding our shares in margin accounts. 

No Pledging of Company Shares 

We have a policy that prohibits any Executive Officer or director from pledging shares issued by us. 

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. 

Executive Compensation Recoupment/Clawback Policy 

Under the Incentive Compensation Recoupment Policy, the Company is authorized to recover or adjust incentive 
compensation to  the  extent  the  Committee  determines  that  payments  or  awards have  exceeded  the  amount  that  would 

P-70 

 
 
 
     
 
 
 
 
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. 

The  Committee  expects  to  update  this  policy  if  and  when  the  SEC  issues  final  rules  on  the  recoupment  of 

executive compensation. 

Tax Impact on Compensation 

To  the  extent  attributable  to  our  United  States  subsidiaries  and  otherwise  deductible,  Section  162(m)  of  the 
Internal Revenue Code (“Section 162(m)”) limits the tax deduction that United States subsidiaries can take with respect 
to the compensation of designated Executive Officers, unless the compensation is “performance-based.” 

Under the 2017 Tax Act, effective for our taxable year beginning January 1, 2018, the exception under Section 
162(m)  for  performance-based  compensation  will  no  longer  be  available,  subject  to  transition  relief  for  certain 
grandfathered  arrangements  in  effect  as  of  November  2,  2017.  Given  the  lack  of  regulatory  guidance  to  date,  the 
Compensation Committee is not yet able to determine the full impact of the 2017 Tax Act changes to Section 162(m) on 
the Company and our compensation programs.

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. 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.

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. Mr. Stobart is the only the Named Executive who participates 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).   

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 Table above. In particular, monthly accrued pension benefits, payable at age 65, were determined 
as of December 31, 2017. The present value of these benefits was calculated based on assumptions used in the Company’s 
financial statements for 2017.   

Transocean Pension Equalization Plan 

The Pension Equalization Plan (“PEP”) is a nonqualified, unfunded, noncontributory pension plan that was frozen 

effective December 31, 2014. Mr. Stobart is the only Named Executive 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) ($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 Table above. In particular, monthly accrued pension benefits, payable at age 65, were determined 
as of December 31, 2017. The present value of these benefits was calculated based on assumptions used in the Company’s 
financial statements for 2017.   

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 median of the total annual compensation of all 
employees of the Company other than the CEO. 

Based on SEC rules for this disclosure and applying the methodology described below, the Company determined 
that our CEO’s total compensation for 2017 was $8,968,889, and the median total 2017 compensation provided to all 
employees was $111,358. Accordingly, the Company estimates the ratio of our CEO’s total compensation for 2017 to the 
median compensation of all employees to be 81 to 1. 

In determining the applicable median salary, we first excluded 218 of our non-U.S. employees located in India, 
representing 4.9% 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   

P-77 

 
 
applicable currency exchange rates in place on December 31, 2017. 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 
base annual salary for all included employees on December 31, 2017, the last day of our fiscal year.   

Once the median employee was identified as described above, the total annual compensation for 2017 for that 
employee was determined using the same rules that apply to reporting NEO compensation in the “Total” column of the 
Summary Compensation Tables. 

P-78 

 
 
Potential Payments Upon Termination or Change of Control 

The  following  tables  and  narrative  disclosure  set  forth  certain  information  with  respect  to  compensation  that 
would be payable to the Named Executive Officers, as of December 31, 2017, upon a variety of termination or change of 
control scenarios. 

As  of  December  31,  2017,  the  Named  Executive  Officers  of  the  Company  were  eligible  for  the  executive 
severance benefit policy. However, members of the Executive Management Team are further subject to the full limitations 
of the Minder Ordinance regarding severance.

not-for-cause termination, the Named Executive Officers would receive a pro-rata portion of the earned PSUs. The performance achievement 
of the PSUs will be determined within 60 days of the end of each three-year performance period and the pro-rata portion of the earned PSUs is 
determined based on the period of time the Named Executive Officer was employed during the performance period. 

(6) The amount of PEP and Savings Restoration Plan benefits included in the table represents the present value of those benefits which would have 

been payable as of December 31, 2017.

Compensation Committee Interlocks and Insider Participation 

OTHER MATTERS 

The members of the Compensation Committee of the Board of Directors during 2017 were Tan Ek Kia, Chairman, 
Frederico F. Curado, Vincent J. Intrieri and Martin B. McNamara, who retired from the Board of Directors on January 30, 
2018. 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 2017, 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 2017. 

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  2019  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 20, 2018. However, if the date of the 2019 
Annual General Meeting changes by more than 30 days from the anniversary of the 2018 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. 

P-83 

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

and, in either case, setting forth the class and number of shares so held, including shares held beneficially;

Cost of Solicitation 

The  accompanying  proxy  is  being  solicited  on  behalf  of  the  Board  of  Directors.  The  expenses  of  preparing,

Co., Inc. (New York) 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.

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

for Awards under this Plan granted wholly or partly in Shares (including rights or Options that may be exercised 
for or settled in Shares) an aggregate of 19,500,000 Shares plus the shares remaining available for awards under

For purposes of clarity, SARs and Options shall be counted in full against the Shares available for issuance under 
this Plan, regardless of the number of Shares issued upon settlement of the SARs and Options.     

(c)  Prior Plan. Shares represented by awards granted under the Prior Plan that are forfeited, expired or canceled 
without delivery of Shares shall again become available for Awards under this Plan, with each such Share that 
relates to (i) awards of Options or SARs granted at any time or awards of Restricted Shares, Restricted Share 
Units, or Performance Units granted prior to May 15, 2009, increasing the Shares available for Awards under this 
Plan by 1.00 Share and (ii) awards of Restricted Shares, Restricted Share Units, or Performance Units granted 
between May 15, 2009 and the Effective Date, increasing the Shares available for Awards under this Plan by 1.68 
Shares.     

(d)  Substitute Awards. The foregoing notwithstanding, subject to applicable securities exchange listing requirements, 
the  number  Shares  available  for  Awards  shall  not  be  reduced  by  (x)  Shares  issued  under  Awards  granted  in 
assumption, substitution or exchange for previously granted awards of a company acquired by the Company and

are  necessary  to  file  any  required  documents  with  governmental  authorities,  stock  exchanges  and  transaction 
reporting systems to ensure that Shares are available for issuance pursuant to Awards.

shall apply to any Awards made hereunder: 

i. 

ii. 

iii. 

iv. 

No Employee may be granted during any calendar year Awards consisting of Options or SARs that are 
exercisable for more than 600,000 Shares; 

No Employee may be granted during any calendar year Awards that are Share-Based Awards covering 
or relating  to more  than 600,000 Shares (the  limitation set  forth  in  this  clause  (ii),  together  with  the 
limitation set forth in clause (i) above, being hereinafter collectively referred to as the “Share-Based 
Award Limitations”); 

No Employee may be granted during any calendar year Awards that may be settled solely in cash having 
a value determined on the Grant Date in excess of $5,000,000; and 

No Director may be granted during any calendar year Director Awards having a value determined on 
the Grant Date in excess of $1,000,000. 

Shares delivered by the Company in settlement of Awards may be authorized and unissued Shares (Shares 

issued out of the Company’s authorized or conditional share capital), Shares held in the treasury of the Company, Shares 
purchased on the open market or by private purchase or any combination of the foregoing. 

6.  Administration. 

(a)  Authority of the Committee. Except as otherwise provided in this Plan with respect to actions or determinations 
by the Board, this Plan shall be administered by the Committee; provided, however, that (i) any and all members 
of the Committee shall satisfy any independence requirements prescribed by any stock exchange on which the 
Company  lists  its  Shares;  (ii)  Awards  may  be  granted  to  individuals  who  are  subject  to  Section  16(b)  of  the 
Exchange Act only if the Committee is composed solely of two or more “Non-Employee Directors” as defined 
in  Securities  and  Exchange  Commission  Rule  16b-3  (as  amended  from  time  to  time,  and  any  successor  rule, 

B-4 

regulation  or  statute  fulfilling  the  same  or  similar  function);  and  (iii)  any  Award  intended  to  qualify  for  the 
“performance-based compensation” exception under Code Section 162(m) shall be granted only if the Committee 
is composed solely of two or more “outside directors” within the meaning of Code Section l62(m) and regulations 
pursuant  thereto.  Subject  to  the  provisions  hereof,  the  Committee  shall  have  full  and  exclusive  power  and 
authority to administer this Plan and to take all actions that are specifically contemplated hereby or are necessary 
or appropriate in connection with the administration hereof. The Committee shall also have full and exclusive 
power to interpret this Plan and to adopt such rules, regulations and guidelines for carrying out this Plan as it may 
deem necessary or proper, all of which powers shall be exercised in the best interests of the Company and in 
keeping with the objectives of this Plan. Subject to Paragraph 6(c) hereof, the Committee may, in its discretion, 
(x) provide for the extension of the exercisability of an Award, or (y) in the event of death, disability, retirement, 
Change of Control or any other reason, accelerate the vesting or exercisability of an Award, eliminate or make 
less restrictive any restrictions contained in an Award, waive any restriction or other provision of this Plan or an 
Award or otherwise amend or modify an Award in any manner that is, in either case, (i) not materially adverse to 
the  Participant  to  whom  such  Award  was  granted,  (ii) consented  to  by  such  Participant  or  (iii)  authorized  by 
Paragraph 15(c)  hereof;  provided,  however,  that  except  as  expressly  provided  in  Paragraph  8(a)(i)  or  8(a)(ii) 
hereof, no such action shall permit the term of any Option or SAR to be greater than 10 years from its Grant Date.   
The Committee may correct any defect or supply any omission or reconcile any inconsistency in this Plan or in 
any Award Agreement in the manner and to the extent the Committee deems necessary or desirable to further this 
Plan’s purposes. Any decision of the Committee in the interpretation and administration of this Plan shall lie 
within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned. The 
Board shall have the same powers as the Committee with respect to Director Awards. 

(b)  Indemnity. No member of the Board or the Chief Executive Officer of the Company to whom the Committee has 
delegated authority in accordance with the provisions of Paragraph 7 of this Plan shall be liable for anything done 
or omitted to be done by such person, by any member of the Board or the Committee or by any officer of the 
Company in connection with the performance of any duties under this Plan, except for his own willful misconduct 
or as expressly provided by statute. 

(c)  Prohibition on Repricing of Awards. Except for adjustments made pursuant to Paragraph 15, in no event will the 
Committee, without first obtaining approval by the majority of the shareholders of the Company, (i) decrease the 
Exercise Price of an Option or SAR after the Grant Date; (ii) accept for surrender to the Company any outstanding 
Option  or  SAR  granted  under  this  Plan  as  consideration  for  the  grant  of  a  new  Option  or  SAR  with  a  lower 
Exercise Price or for the grant of any other Award; (iii) repurchase from Participants whether for cash or any 
other consideration any outstanding Options or SARs that have an Exercise Price per share higher than the then 
current Fair Market Value of a Share; or (iv) grant any Option or SAR that contains a so-called “reload” feature 
under which additional Options, SARs or other Awards are granted automatically to the Participant upon exercise 
of the original Option or SAR. 

7.  Delegation of Authority. The Committee may delegate any of its authority to grant Awards to Employees who are 
not subject to Section 16(b) of the Exchange Act subject to Paragraph 6(a) above, to the Board or the Chief Executive 
Officer  of  the  Company,  provided  such  delegation  is  made  in  writing  and  specifically  sets  forth  such  delegated 
authority. The Committee  and  the  Board,  as  applicable, may engage  or  authorize  the engagement  of  a  third  party 
administrator  to  carry  out  administrative  functions  under this  Plan.    Any  such delegation hereunder shall  only  be 
made to the extent permitted by applicable law. 

8.  Employee Awards. 

(a)  Award Provisions. The Committee shall determine the type or types of Employee Awards to be made under this 
Plan and shall designate from time to time the Employees who are to be the recipients of such Awards. Each 
Employee Award shall be embodied in an Award Agreement, which shall contain such terms, conditions and 
limitations as shall be determined by the Committee, in its sole discretion, and, if required by the Committee, 
shall be signed by the Participant to whom the Award is granted and by the Company. Awards may consist of 
those listed in this Paragraph 8(a) and may be granted singly, in combination or in tandem. Awards may also be 
made in combination or in tandem with, in replacement of, or as alternatives to, grants or rights under this Plan 
or any other plan of the Company or any of its Subsidiaries, including the plan of any acquired entity. All or part 
of an Award may be subject to conditions established by the Committee. Upon the termination of employment 
by a Participant who is an Employee, any unexercised, unvested or unpaid Awards shall be treated as set forth in 

B-5 

the  applicable  Award  Agreement  or  in  any  other  written  agreement  the  Company  has  entered  into  with  the 
Participant.

Options. An Employee Award may be in the form of an Option. An Option awarded pursuant to this 
Plan may consist of either an Incentive Stock Option or a Nonqualified Stock Option. The Exercise Price 
of an Option shall be not less than the Fair Market Value of the Shares on the Grant Date, subject to 
adjustment as provided in Paragraph 15 hereof. The term of an Option shall not exceed 10 years from 
the Grant Date. Subject to the foregoing provisions, the terms, conditions and limitations applicable to 
any Option, including, but not limited to, the term of any Option and the date or dates upon which the 
Option becomes vested and exercisable, shall be determined by the Committee. 

Share Appreciation Rights. An Employee Award may be in the form of an SAR. The Exercise Price for 
an  SAR  shall  not  be  less  than  the  Fair  Market  Value  of  the  Shares  on  the  Grant  Date,  subject  to 
adjustment as provided in Paragraph 15 hereof. The holder of a tandem SAR may elect to exercise either 
the Option or the SAR, but not both.    The exercise period for an SAR shall extend no more than 10 
years after the Grant Date. Subject to the foregoing provisions, the terms, conditions, and limitations 
applicable to any SAR, including, but not limited to, the term of any SAR and the date or dates upon 
which the SAR becomes vested and exercisable, shall be determined by the Committee. 

Restricted Share Awards. An Employee Award may be in the form of a Restricted Share Award. The 
terms, conditions and limitations applicable to any Restricted Share Award, including, but not limited 
to, the Restriction Period, shall be determined by the Committee. 

Restricted  Share  Unit  Awards.  An  Employee  Award  may  be  in  the  form  of  a  Restricted  Share  Unit 
Award.    The terms, conditions and limitations applicable to a Restricted Share Unit Award, including, 
but not limited to, the Restriction Period, shall be determined by the Committee. Subject to the terms of 
this Plan, the Committee, in its sole discretion, may settle Restricted Share Units in the form of cash or 
in Shares (or in a combination thereof) equal to the value of the vested Restricted Share Units. 

Performance Unit  Awards. An  Employee  Award  may  be  in  the  form  of  a  Performance  Unit  Award.   
Subject to the terms of this Plan, after the applicable performance period has ended, the Participant shall 
be entitled to receive settlement of the value and number of Performance Units earned by the Participant 
over the performance period, as determined based on the extent to which the corresponding performance 
objectives have been achieved.    Settlement of earned Performance Units shall be as determined by the 
Committee and as evidenced in an Award Agreement.    Subject to the terms of this Plan, the Committee, 
in  its  sole  discretion,  may  settle  earned  Performance  Units  in  the  form  of  cash  or  in  Shares  (or  in  a 
combination thereof) equal to the value of the earned Performance Units as soon as practicable after the 
end  of  the  performance  period  and  following  the  Committee’s  determination  of  actual  performance 
against the performance measures and related goals established by the Committee. 

Cash Awards. An Employee Award may be in the form of a Cash Award. The terms, conditions and 
limitations applicable to a Cash Award, including, but not limited to, vesting or other restrictions, shall 
be determined by the Committee. 

Performance Awards. Without limiting the type or number of Awards that may be made under the other 
provisions of this Plan, an Employee Award may be in the form of a Performance Award. The terms, 
conditions and limitations applicable to an Award that is a Performance Award shall be determined by 
the Committee. The Committee shall set Performance Objectives in its discretion which, depending on 
the extent to which they are met, will determine the value and/or amount of Performance Awards that 
will be paid out to the Participant and/or the portion of an Award that may be exercised. 

(A)  Nonqualified Performance Awards. Performance Awards granted to Employees that are not 
intended  to  qualify  as  qualified  performance-based  compensation  under  Code  Section 
162(m) shall be based on achievement of such Performance Objectives and be subject to such 
terms, conditions and restrictions as the Committee or its delegate shall determine. 

B-6 

(B)  Qualified Performance Awards. Performance Awards granted to Employees under this Plan 
that are intended to qualify as qualified performance-based compensation under Code Section 
162(m)  (“Qualified  Performance  Awards”)  shall  be  paid,  vested  or  otherwise  deliverable 
solely on account of the attainment of one or more pre-established, objective Performance 
Objectives established by the Committee prior to the earlier to occur of (1) 90 days after the 
commencement  of  the  period  of  service  to  which  the  Performance  Objective  relates  and 
(2) the lapse of 25% of the period of service (as scheduled in good faith at the time the goal 
is established), and in any event while the outcome is substantially uncertain. A Performance 
Objective is objective if a third party having knowledge of the relevant facts could determine 
whether the goal is met. One or more of such goals may apply to the Employee, one or more 
business units, divisions or sectors of the Company, or the Company as a whole, and if so 
desired by the Committee, by comparison with a peer group of companies. A Performance 
Objective shall include one or more of the following: (1) increased revenue; (2) net income 
measures (including but not limited to income after capital costs and income before or after 
taxes);  (3)  Share  price  measures  (including  but  not  limited  to  growth  measures  and  total 
shareholder  return);  price  per  Share;  market  share;  earnings  per  Share  (actual  or  targeted 
growth);  (4)  earnings  before  interest,  taxes,  depreciation,  and  amortization  (“EBITDA”); 
(5) economic  value  added  (or  an  equivalent  metric);  (6)  market  value  added;  (7)  debt  to 
equity ratio; (8) cash flow measures (including but not limited to cash flow return on capital, 
cash  flow  return  on  tangible  capital,  net  cash  flow  and  net  cash  flow  before  financing 
activities  cash  flow  value  added,  cash  flow  return  on  market  capitalization);  (9)  return 
measures (including but not limited to return on equity, return on average assets, return on 
capital,  risk-adjusted  return  on  capital,  return  on  investors’  capital  and  return  on  average 
equity); (10) operating measures (including operating income, funds from operations, cash 
from  operations,  after-tax  operating  income;  sales  volumes,  production  volumes  and 
production efficiency); (11) expense measures (including but not limited to overhead cost 
and general and administrative expense cost control and project management); (12) margins; 
(13) shareholder value; (14) total shareholder return; (15) proceeds from dispositions; and 
(16)  total  market  value  and  corporate  values  measures  (including  ethics  compliance, 
environmental, human resources development and safety). 

Unless otherwise stated, such a Performance Objective need not be based upon an increase 
or  positive  result  under  a  particular  business  criterion  and  could  include,  for  example, 
maintaining the status quo or limiting economic losses (measured, in each case, by reference 
to  specific  business  criteria).    In  interpreting  Plan  provisions  applicable  to  Qualified 
Performance  Awards,  it  is  the  intent  of  this  Plan  to  conform  with  the  standards  of  Code 
Section 162(m) and Treasury Regulation § 1.162-27(e)(2)(i), as to grants to Employees, who 
are or may be “covered employees,” as defined in Code Section 162(m), and the Committee 
in  establishing  such  goals  and  interpreting  this  Plan  shall  be  guided  by  such  provisions.   
Prior  to  the  payment  of  any  compensation  based  on  the  achievement  of  Performance 
Objectives  applicable  to  Qualified  Performance  Awards,  the  Committee  must  certify  in 
writing that applicable Performance Objectives and any of the material terms thereof were, 
in fact, satisfied.    For this purpose, approved minutes of the Committee meeting in which 
the  certification  is  made  shall  be  treated  as  such  written  certification.    Subject  to  the 
foregoing  provisions,  the  terms,  conditions  and  limitations  applicable  to  any  Qualified 
Performance Awards made pursuant to this Plan shall be determined by the Committee. 

(b)  Minimum Vesting. Subject to Paragraph 6(a) hereof, all Employee Awards shall have a minimum vesting period 

or Restriction Period, as applicable, of one year from the Grant Date. 

9.  Director Awards. The Board has the sole authority to grant Director Awards from time to time in accordance with 
this Paragraph 9. Director Awards may consist of the forms of Award described in Paragraph 8, with the exception of 
Options, SARs, Performance Awards and Cash Awards, and shall be granted subject to such terms and conditions as 
specified  in  Paragraph  8.  Each  Director  Award  may,  in  the  discretion  of  the  Board,  be  embodied  in  an  Award 
Agreement, which shall contain such terms, conditions, and limitations as shall be determined by the Board, in its sole 
discretion. Subject to Paragraph 6(a) hereof, all Director Awards shall vest at such time as the Board may designate 
in  its  sole  discretion,  but  not  earlier  than  the  first  to  occur  of  (a) the  first  anniversary  of  the  Grant  Date  of 

B-7 

such Director Award or (b) the date of the annual general meeting of the Board next following the Grant Date of such 
Director Award. 

10.  Award Payment; Dividends and Dividend Equivalents. 

(a)  General. Payment of Awards may be made in the form of cash or Shares, or a combination thereof, and may 
include  such  restrictions  as  the  Committee  (or  the  Board,  in  the  case  of  Director  Awards)  shall  determine, 
including,  but  not  limited  to,  in  the  case  of  Shares,  restrictions  on  transfer  and  forfeiture  provisions.  For  a 
Restricted Share Award, the certificates evidencing the shares of such Restricted Shares (to the extent that such 
shares are so evidenced) shall contain appropriate legends and restrictions that describe the terms and conditions 
of the restrictions applicable thereto. For a Restricted Share Unit Award that may be settled in Shares, the Shares 
that may be issued at the end of the Restriction Period shall be evidenced by book entry registration or in such 
other manner as the Committee may determine. 

(b)  Dividends and Dividend Equivalents. Rights to (i) dividends will be extended to and made part of any Restricted 
Share Award and (ii) Dividend Equivalents may be extended to and made part of any Restricted Share Unit Award 
and Performance Unit Award, subject in each case to such terms, conditions and restrictions as the Committee 
may  establish;  provided,  however,  that  no  such  Dividend  Equivalents  shall  be  paid  with  respect  to  unvested 
Restricted  Share  Unit  Awards  or  Performance  Unit  Awards.  Dividend  Equivalents  with  respect  to  unvested 
Restricted  Share  Unit  Awards  or  Performance  Unit  Awards  may,  in  the  discretion  of  the  Committee,  be 
accumulated and paid to the Participant at the time that such Restricted Share Unit Award or Performance Unit 
Award vests. Dividends and/or Dividend Equivalents shall not be made part of any Options or SARs. 

11.  Option  Exercise.  The  Exercise  Price  shall  be  paid  in  full  at  the  time  of  exercise  in  cash  or,  if  permitted  by  the 
Committee  and  elected  by  the  Participant,  the  Participant  may  purchase  such  shares  by  means  of  the  Company 
withholding Shares otherwise deliverable on exercise of the Award or tendering Shares valued at Fair Market Value 
on the date of exercise, or any combination thereof. The Committee, in its sole discretion, shall determine acceptable 
methods for Participants to tender Shares or other Awards. The Committee may provide for procedures to permit the 
exercise or purchase of such Awards by use of the proceeds to be received from the sale of Shares issuable pursuant 
to  an  Award  (including  cashless  exercise  procedures  approved  by  the  Committee  involving  a  broker  or  dealer 
approved by the Committee). The Committee may adopt additional rules and procedures regarding the exercise of 
Options from time to time, provided that such rules and procedures are not inconsistent with the provisions of this 
Paragraph 11. 

12.  Taxes. The Company shall have the right to deduct applicable taxes from any Award payment and withhold, at the 
time of delivery or vesting of cash or Shares under this Plan, an appropriate amount of cash or number of Shares or a 
combination thereof for payment of required withholding taxes or to take such other action as may be necessary in the 
opinion of the Company to satisfy all obligations for withholding of such taxes; provided, however, that the number 
of  Shares  withheld  for  payment  of  required  withholding  taxes  must  equal  no  more  than  the  required  minimum 
withholding taxes. The Committee may also permit withholding to be satisfied by the transfer to the Company of 
Shares theretofore owned by the holder of the Award with respect to which withholding is required.    If Shares are 
used to satisfy tax withholding, such Shares shall be valued based on the Fair Market Value when the tax withholding 
is required to be made. 

13.  Amendment, Modification, Suspension or Termination. The Board may amend, modify, suspend or terminate this 
Plan (and the Committee may amend an Award Agreement) for the purpose of meeting or addressing any changes in 
legal requirements or for any other purpose permitted by law, except that (i) no amendment or alteration that would 
materially adversely affect the rights of any Participant under any Award previously granted to such Participant shall 
be made without the consent of such Participant and (ii) no amendment or alteration shall be effective prior to its 
approval by the shareholders of the Company to the extent shareholder approval is otherwise required by applicable 
legal requirements or the requirements of the securities exchange on which the Company’s shares are listed, including 
any amendment that expands the types of Awards available under this Plan, materially increases the number of Shares 
available for Awards under this Plan, materially expands the classes of persons eligible for Awards under this Plan, 
materially extends the term of this Plan, materially changes the method of determining the Exercise Price of Options, 
or deletes or limits any provisions of this Plan that prohibit the repricing of Options or SARs. 

B-8 

14.  Assignability.  Unless  otherwise  determined  by  the  Committee  (or  the  Board  in  the  case  of  Director  Awards)  or 
expressly provided for in an Award Agreement, no Award or any other benefit under this Plan shall be assignable or 
otherwise transferable except (i) by will or the laws of descent and distribution or (ii) pursuant to a domestic relations 
order  issued  by  a  court  of  competent  jurisdiction  that  is  not  contrary  to  the  terms  and  conditions  of  this  Plan  or 
applicable Award and in a form acceptable to the Committee. The Committee may prescribe and include in applicable 
Award Agreements other restrictions on transfer. Any attempted assignment of an Award or any other benefit under 
this Plan in violation of this Paragraph 14 shall be null and void. Notwithstanding the foregoing, no Award may be 
transferred for value or consideration. 

15.  Adjustments. 

(a)  The existence of outstanding Awards shall not affect in any manner the right or power of the Company or its 
shareholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in 
the capital stock of the Company or its business or any merger or consolidation of the Company, or any issue of 
bonds, debentures, preferred or prior preference stock (whether or not such issue is prior to, on a parity with or 
junior to Shares) or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its 
assets or business, or any other corporate act or proceeding of any kind, whether or not of a character similar to 
that of the acts or proceedings enumerated above. 

(b)  In  the  event  of  any  subdivision  or  consolidation  of  outstanding  Shares,  declaration  of  a  dividend  payable  in 
Shares, combination of shares, or other stock split, then (1) the number of Shares reserved under this Plan, (2) the 
number of Shares covered by outstanding Awards in the form of Shares or units denominated in Shares, (3) the 
Exercise  Price  or  other  price  in  respect  of  such  Awards,  (4)  the  Share-Based  Award  Limitations,  and  (5)  the 
appropriate  Fair  Market  Value  and  other  price  determinations  for  such  Awards  shall  each  be  proportionately 
adjusted by the Committee as appropriate to reflect such transaction. In the event of any other recapitalization or 
capital reorganization of the Company, any consolidation or merger of the Company with another corporation or 
entity,  the  adoption  by  the  Company  of  any  plan  of  exchange  affecting  the  Shares,  rights  offer,  dissolution, 
demerger,  conversion,  spin-off,  or  any  distribution  to  holders  of  Shares  of  securities  or  property  (other  than 
normal cash dividends or dividends payable in Shares), the Committee shall make appropriate adjustments to (i) 
the number of Shares reserved under this Plan, (ii) the number and kind of Shares covered by Awards in the form 
of Shares or units denominated in Shares, (iii) the Exercise Price or other price in respect of such Awards, (iv) 
the  appropriate  Fair  Market  Value  and  other  price  determinations  for  such  Awards,  and  (v)  the  Share-Based 
Award Limitations to reflect such transaction; provided that such adjustments shall only be such as are necessary 
to maintain the proportionate interest of the holders of the Awards and preserve, without increasing, the value of 
such Awards. 

(c)  In the event of a corporate merger, consolidation, acquisition of property or stock, separation, reorganization or 
liquidation,  the  Committee  may  make  such  adjustments  to  Awards  or  other  provisions  for  the  disposition  of 
Awards as it deems equitable, and shall be authorized, in its discretion, (i) to provide for the substitution of a new 
Award or other arrangement (which, if applicable, may be exercisable for such property or stock as the Committee 
determines) for an Award or the assumption of the Award, regardless of whether in a transaction to which Code 
Section 424(a) applies, (ii) to provide, prior to the transaction, for the acceleration of the vesting and exercisability 
of, or lapse of restrictions with respect to, the Award and, if the transaction is a cash merger, provide for the 
termination of any portion of the Award that remains unexercised at the time of such transaction, or (iii) to cancel 
any such Awards and to deliver to the Participants cash in an amount that the Committee shall determine in its 
sole discretion is equal to the Fair Market Value of such Awards on the date of such event, which in the case of 
Options or Share Appreciation Rights shall be the excess (if any) of the Fair Market Value of Shares on such date 
over the Exercise Price of such Award. 

(d)  No  adjustment  or  substitution  pursuant  to  this  Paragraph  15  shall  be  made  in  a  manner  that  results  in 

noncompliance with the requirements of Code Section 409A, to the extent applicable. 

16.  Restrictions. No Shares or other form of payment shall be issued with respect to any Award unless the Company 

shall be satisfied based on the advice of its counsel that such issuance will be in compliance with applicable federal 
and state securities and other laws. Certificates evidencing Shares delivered under this Plan (to the extent that such 
Shares are so evidenced) may be subject to such stop transfer orders and other restrictions as the Committee may 
deem advisable under the rules, regulations and other requirements of the Securities and Exchange Commission, any 

B-9 

securities exchange or transaction reporting system upon which the Shares are then listed or to which it is admitted 
for quotation and any applicable federal or state securities or other laws. The Committee may cause a legend or 
legends to be placed upon such certificates (if any) to make appropriate reference to such restrictions. 

17.  Unfunded Plan. This Plan is unfunded. Although bookkeeping accounts may be established with respect to 

Participants who are entitled to cash, Shares or rights thereto under this Plan, any such accounts shall be used 
merely as a bookkeeping convenience. The Company shall not be required to segregate any assets that may at any 
time be represented by cash, Shares or rights thereto, nor shall this Plan be construed as providing for such 
segregation, nor shall the Company, the Board or the Committee be deemed to be a trustee of any cash, Shares or 
rights thereto to be granted under this Plan. Any liability or obligation of the Company to any Participant with 
respect to an Award of cash, Shares or rights thereto under this Plan shall be based solely upon any contractual 
obligations that may be created by this Plan and any Award Agreement, and no such liability or obligation of the 
Company shall be deemed to be secured by any pledge or other encumbrance on any property of the Company.   
None of the Company, the Board or the Committee shall be required to give any security or bond for the 
performance of any obligation that may be created by this Plan. With respect to this Plan and any Awards granted 
hereunder, Participants are general and unsecured creditors of the Company and have no rights or claims except as 
otherwise provided in this Plan or any applicable Award Agreement. 

18.  Code Section 409A. 

(a)  Awards made under this Plan are intended to comply with or be exempt from Code Section 409A, and ambiguous 
provisions hereof, if any, shall be construed and interpreted in a manner consistent with such intent. No payment, 
benefit or consideration shall be substituted for an Award if such action would result in the imposition of taxes 
under Code Section 409A. Notwithstanding anything in this Plan to the contrary, if any Plan provision or Award 
under this Plan would result in the imposition of an additional tax under Code Section 409A, that Plan provision 
or  Award  shall  be  reformed,  to  the  extent  permissible  under  Code  Section  409A,  to  avoid  imposition  of  the 
additional tax, and no such action shall be deemed to adversely affect the Participant’s rights to an Award.   

(b)  Unless  the  Committee  provides  otherwise  in  an  Award  Agreement,  each  Restricted  Share  Unit  Award, 
Performance Unit Award or Cash Award (or portion thereof if the Award is subject to a vesting schedule) shall 
be settled no later than the 15th day of the third month after the end of the first calendar year in which the Award 
(or such portion thereof) is no longer subject to a “substantial risk of forfeiture” within the meaning of Code 
Section 409A. If the Committee determines that a Restricted Share Unit Award, Performance Unit Award or Cash 
Award is intended to be subject to Code Section 409A, the applicable Award Agreement shall include terms that 
are designed to satisfy the requirements of Code Section 409A. 

(c)  If the Participant is identified by the Company as a “specified employee” within the meaning of Code Section 
409A(a)(2)(B)(i) on the date on which the Participant has a “separation from service” (other than due to death) 
within  the  meaning  of  Treasury  Regulation  §  1.409A-1(h),  any  Award  payable  or  settled  on  account  of  a 
separation from service that is deferred compensation subject to Code Section 409A shall be paid or settled on 
the earliest of (i) the first business day following the expiration of six months from the Participant’s separation 
from service, (ii) the date of the Participant’s death, or (iii) such earlier date as complies with the requirements of 
Code Section 409A. 

19.  Governing Law. This Plan and all determinations made and actions taken pursuant hereto, to the extent not 
otherwise governed by mandatory provisions of the Code or the securities laws of the United States, shall be 
governed by and construed in accordance with the laws of the State of Texas. 

20.  Right to Continued Service or Employment. Nothing in this Plan or an Award Agreement shall interfere with or 
limit in any way the right of the Company or any of its Subsidiaries to terminate any Participant’s employment or 
other service relationship with the Company or its Subsidiaries at any time, nor confer upon any Participant any 
right to continue in the capacity in which such Participant is employed or otherwise serves the Company or its 
Subsidiaries. 

21.  Non-Uniform Determinations. Determinations by the Committee or the Board under this Plan (including, without 
limitation, determinations of the persons to receive Awards under this Plan; the form, amount and timing of such 
Awards; the terms and provisions of such Award Agreements evidencing same; and provisions with respect to 

B-10 

termination of employment or service) need not be uniform and may be made by it selectively among persons who 
receive, or are eligible to receive, awards under this Plan, whether or not such persons are similarly situated. 

22.  Clawback Right. Notwithstanding any other provisions in this Plan, any Award shall be subject to recovery or 

clawback by the Company under any clawback policy adopted by the Company whether before or after the Grant 
Date of the Award. 

23.  Usage. Words used in this Plan in the singular shall include the plural and in the plural the singular, and the gender 
of words used shall be construed to include whichever may be appropriate under any particular circumstances of the 
masculine, feminine or neuter genders. 

24.  Headings. The headings in this Plan are inserted for convenience of reference only and shall not affect the meaning 

or interpretation of this Plan. 

25.  Effectiveness. This Plan shall be effective as of the Effective Date. This Plan shall continue until terminated by 
action of the Board. Notwithstanding the foregoing, the adoption of this Plan is expressly conditioned upon the 
approval by the holders of a majority of Shares present, or represented, and entitled to vote at the 2015 annual 
general meeting of the Company’s shareholders. If the shareholders of the Company should fail to so approve this 
Plan at such meeting, (i) this Plan shall not be of any force or effect and (ii) any grants of Awards hereunder shall be 
null and void.

To the General Meeting of  

Transocean Ltd., Steinhausen  

Zurich, March 9, 2018 

Report of the statutory auditor on the compensation report 

We have audited the compensation report (pages CR-2 to CR-5) of Transocean Ltd. for the year ended December 31, 2017. 

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 accompanying 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,  2017  of  Transocean Ltd.  complies  with  Swiss  law  and 
articles 14 – 16 of the Ordinance.

General 

Transocean Ltd. (“Transocean”, “we”, “us”, or “our”) is the parent company of Transocean Inc., Transocean Management Ltd., and 
Transocean Management Services GmbH., our direct wholly-owned subsidiaries.  Transocean is registered with the commercial register in

(“SIX”).  Effective on March 31, 2016, at our request, our shares were delisted from the SIX. 

This  Compensation  Report  reflects  the  requirements  of  Articles 13–16  of  the  Swiss  Federal  Ordinance  Against  Excessive 
Compensation in Public Corporations, and discloses any compensation paid to our members of the Board of Directors and the Executive 
Management Team for the years ended December 31, 2017 and 2016.  For a description of our governance framework relating to executive 
and  director  compensation,  please  refer  to  page P-39  et seq.  of  our  2018  Proxy  Statement  under  the  caption  "Executive  and  Director 
Compensation Process."  For a description of our directors' compensation principles, please refer to page P-43 et seq. of our 2018 Proxy 
Statement under the captions "Director Compensation Strategy" and "2017 Director Compensation."  For a description of our Executive

"Compensation Discussion and Analysis." 

For the years ended December 31, 2017 and 2016, we have presented all compensation amounts in U.S. dollars and Swiss francs 

using the average annual currency exchange rate of USD 1.00 to CHF 0.99 and CHF 0.98, respectively.

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, 2017 and December 31, 2016. 

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 vested units or the shares 
attributable to such vested units, upon vesting or to have us hold such vested units, or shares attributable to such vested units, until the 
director no longer serves on the board. 

Certain  members  of  our  Board  of  Directors  received  compensation  for  service  on  the  Board  of  Directors  of  Transocean 
Partners LLC (“Transocean Partners”), our consolidated subsidiary.  On December 9, 2016, Transocean Partners completed a merger with 
one of our subsidiaries as contemplated under the Agreement and Plan of Merger, dated July 31, 2016, and as amended on November 21, 
2016.  Following the completion of the merger, Transocean Partners continued as the surviving company and is a wholly owned indirect 
subsidiary of Transocean Ltd.

TRANSOCEAN LTD. 
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, 2017 and 2016, 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 19, 
2018, we owned or had partial ownership interests in and operated 47 mobile offshore drilling units.  As of February 19, 2018, our fleet 
consisted of 27 ultra-deepwater floaters, 12 harsh environment floaters, two deepwater floaters and six midwater floaters.  At February 19, 
2018,  we  also  had  two ultra-deepwater  drillships  under  construction  or  under  contract  to  be  constructed.    Additionally,  we  operated 
two high-specification jackups that were under contract when we sold the rigs, and we continue to operate such rigs until completion or 
novation of the respective drilling contracts. 

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.  We believe 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 18—Operating Segments, Geographic Analysis and Major Customers.” 

Recent Developments 

Business combination—On August 13, 2017, we entered into the Transaction Agreement with Songa Offshore SE, a European 
public company limited by shares, or societas Europaea, existing under the laws of Cyprus (“Songa”).  On January 30, 2018, we completed 
our acquisition of an approximate 97.7 percent ownership interest in Songa.  By March 31, 2018, we expect to complete the acquisition of 
the remaining shares not owned by us through a compulsory acquisition, which is available to us under Cyprus law.  In connection with the 
acquisition,  we  acquired  seven mobile  offshore  drillings  units,  including  five harsh  environment  floaters  and  two midwater  floaters.    In 
connection with the acquisition, we issued 66.9 million shares and an aggregate principal amount of $854 million of the 0.5% Exchangeable 
Senior Bonds due January 2023.  See “Part II. Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial 
Statements and —Note 20—Subsequent Event.” 

Drilling Fleet 

Fleet overview—Our drilling fleet of floaters consists of drillships and semisubmersibles.  Most of our drilling equipment is suitable 
for both exploration and development, and we normally engage in both types of drilling activity.  All of our drilling rigs are mobile and can be 
moved to new locations in response to customer demand.  All of 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.  All 
of our drillships are ultra-deepwater capable and equipped with a computer-controlled dynamic positioning thruster system, which allows 
them to maintain position without anchors through the use of their onboard propulsion and station-keeping systems.  These rigs 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 17 ultra-deepwater drillships that are, and two ultra-deepwater drillships under construction 
that will be, equipped with our patented dual-activity technology.  Dual-activity technology employs structures, equipment and techniques 
using two drilling stations within a dual derrick to allow these drillships to perform simultaneous drilling tasks in a parallel, rather than a 
sequential manner, which reduces critical path activity and improves efficiency in both exploration and development drilling.  In addition to 
dynamic positioning thruster systems, dual-activity technology, industry-leading hoisting capacity and a second blowout preventer system, 
our two newbuild drillships under construction will be outfitted to accommodate a future upgrade to a 20,000 pounds per square inch (“psi”) 
blowout preventer. 

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.  These rigs are capable of maintaining their position 
over  a  well  through  the  use  of  an  anchoring  system  or  a  computer-controlled  dynamic  positioning  thruster  system.    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.  Typically, semisubmersibles are capable of operating in rougher sea conditions than drillships.  We have 

AR-2 

 
two custom-designed, high-capacity, dual-activity semisubmersible drilling rigs, equipped for year-round operations in harsh environments, 
including those of the Norwegian continental shelf and sub-Arctic waters.  Five of our 24 semisubmersibles are equipped with our patented 
dual-activity technology and also have mooring capability. 

Fleet  categories—We  further  categorize  the  drilling  units  of  our  fleet  as  follows:  (1) “ultra-deepwater  floaters,”  (2) “harsh 
environment floaters,” (3) “deepwater floaters” and (4) “midwater floaters”.  Ultra-deepwater floaters are equipped with high-pressure mud 
pumps  and  are  capable  of  drilling  in  water  depths  of  7,500 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.  Deepwater floaters are generally those other semisubmersible rigs and drillships 
capable of drilling in water depths between 4,500 and 7,500 feet.  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 19,  2018,  we  owned  and  operated  a  fleet  of  47 rigs,  including  the  seven rigs  recently  acquired  in  the  Songa 

acquisition and excluding two newbuilds under construction, as follows: 

(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 

27 ultra-deepwater floaters; 
12 harsh environment floaters; 
Two deepwater floaters; and 
Six 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 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, 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, from time to time, consider marketing 
stacked rigs as accommodation units or for other alternative uses until drilling activity increases and we obtain drilling contracts for these 
units.  We may not return some stacked rigs to work for drilling services or for these alternative uses. 

Drilling units—The following tables, presented as of February 19, 2018, provide certain specifications for our rigs, including the 
seven rigs recently acquired in the Songa acquisition.  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 19, 2018, we owned all of the drilling rigs in our fleet noted in the tables below, except for the following: (1) the ultra-deepwater 
floater Petrobras 10000, which is subject to a capital lease through August 2029, and (2) the ultra-deepwater floater Discoverer Luanda, 
which is owned through our 65 percent ownership interest in Angola Deepwater Drilling Company Ltd. (“ADDCL”).

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 capture demand in another locale.  Consequently, we cannot predict the percentage of our revenues that will be derived 
from particular geographic or political areas in future periods. 

As of February 19, 2018, our drilling fleet, including stacked and idle rigs, but excluding rigs under construction, was located in the 
(“U.S.”) Gulf of Mexico (ten units),  Trinidad (seven units),  United  Kingdom 
India (three units),  Canada (two units),  Aruba (one unit),  Australia (one unit), 

Norwegian North Sea (ten units), 
(“U.K.”) North Sea (five units),  Malaysia (four units), 
Brazil (one units), Ivory Coast (one unit), Myanmar (one unit), and Romania (one unit). 

the  United  States 

We  categorize  the  market  sectors  in  which  we  operate  as  follows:  (1) ultra-deepwater,  (2) deepwater  and  (3) midwater.    The 
ultra-deepwater,  deepwater  and  midwater  market  sectors,  collectively  known  as  the  floater  market,  are  serviced  by  our  drillships  and 
semisubmersibles, 12 of which are suited to work in harsh environments.  We generally view the ultra-deepwater market sector as water 
depths beginning at 7,500 feet and extending to the maximum water depths in which rigs are capable of drilling, which is currently up to 
12,000 feet.  The deepwater market sector services water depths beginning at approximately 4,500 feet to approximately 7,500 feet, and the 
midwater market sector services water depths from approximately 300 feet to approximately 4,500 feet. 

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. 

The industry is continuing to experience a cyclical downturn.  A multi-year weak commodity pricing environment has resulted in 
our customers delaying investment decisions and postponing exploration and production programs.  Relative to years prior to the downturn, 
we have experienced significantly reduced demand, resulting in a decline in the execution of drilling contracts for the global offshore drilling 
fleet and an unprecedented level of early terminations and cancellations of drilling contracts.  Over the past year, however, 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  is  resulting  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 continues and has delayed improvement of dayrates.  However, 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.  In this environment, older and less capable assets are more likely to be permanently retired, ultimately reducing the available 
supply of drilling rigs.  During the years ended December 31, 2017, 2016 and 2015, we sold for scrap value three, 11 and 17 drilling units, 
respectively, and at December 31, 2017, 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 commodity prices stabilize and confidence improves in the stability of such price levels, 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 provisions.  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 zero rates 
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, 2017, the contract backlog was approximately $9.5 billion, representing a decrease of 19 percent 
and 41 percent, respectively, compared to the contract backlog at December 31, 2016 and 2015, which was $11.7 billion and $16.0 billion, 
respectively.  See “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—
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, or 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 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.”

Consistent with standard industry practice, our customers generally assume, and indemnify us against, well control and subsurface 
risks under dayrate drilling contracts.  Under all of our current drilling contracts, our customers, as the operators, indemnify us for pollution 
damages in connection with reservoir fluids stemming from operations under the contract and we indemnify the operator for pollution from 
substances in our control that originate from the rig, such as diesel used onboard the rig or other fluids stored onboard the rig and above the 
water surface.  Also, under all of our current drilling contracts, the operator indemnifies us against damage to the well or reservoir and 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 the operator against the liabilities discussed above can 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  statement  of  financial  position,  results  of  operations  or  cash  flows.    See  “Part II.  Item 8.  Financial  Statements  and 
Supplementary Data—Notes to Consolidated Financial Statements—Note 10—Commitments and Contingencies.” 

Significant Customers 

We engage in offshore drilling services for most of the leading international oil companies or their affiliates, as well as for many 
government-controlled  oil  companies  and  independent  oil  companies.    For  the  year  ended  December 31,  2017,  our  most  significant 
customers were Chevron Corporation (together with its affiliates, “Chevron”), Royal Dutch Shell plc (together with its affiliates, “Shell”) and 
Petróleo Brasileiro S.A. (“Petrobras”), representing approximately 29 percent, 17 percent and 14 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, 2017.  Additionally, as of February 19, 2018, the customers with the most significant aggregate amount of contract backlog 
associated with our drilling contracts were Shell, Statoil ASA (together with its affiliates, “Statoil”) and Chevron, representing approximately 
52 percent,  31 percent  and  10 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 a material adverse impact on our consolidated statement of 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,  2017,  we  had  approximately  4,900 employees,  including  approximately  400 persons  engaged 
through contract labor providers.  Approximately 26 percent of our total workforce, working primarily in Brazil, Norway and the U.K. are 
represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially all of which are subject 
to annual salary negotiation.  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.  We may or may not control these joint ventures.  We participate in several joint venture drilling companies, principally 
in Angola, Indonesia, Malaysia and Nigeria.  Local laws or customs in some areas of the world also 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.  At 
December 31, 2017, joint ventures in which we participate were as follows: 

We hold a 65 percent interest in ADDCL, a consolidated Cayman Islands joint venture company formed to own Discoverer Luanda.  
Our  local  partner,  Angco  Cayman Limited,  a  Cayman  Islands  company,  holds  the  remaining  35 percent  interest  in  ADDCL.    Angco 
Cayman Limited has the right to exchange its interest in the joint venture for cash at an amount based on an appraisal of the fair value of the 
drillship, subject to certain adjustments. 

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.

have been formed to perform certain management services and other onshore support services for our operations. 

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-two drillships and semisubmersibles in our existing fleet are, and our two drillships that are under construction will be, 
equipped with our patented dual-activity technology, which allows our rigs to perform simultaneous drilling tasks in a parallel rather than 
sequential manner 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 
two 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 our two drillships that are under construction will be, designed to accept 20,000 psi blowout preventers in the future.  
Six of our harsh environment semi-submersibles are designed and constructed specifically to provide highly efficient performance offshore 
Norway 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 a global environmental standard.  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.”

Risk Factors 

Risks related to our business 

(cid:131)  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: 

(cid:131) 
(cid:131)

(cid:131) 
(cid:131) 

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  drive  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 contributed to oil 
and gas price volatility and are likely to do so in the future. 

(cid:131) 

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 has historically been cyclical and is impacted by oil and natural gas price levels and volatility.  There 
have been periods of high customer demand, limited rig supply and high dayrates, followed by periods of low customer demand, excess rig 
supply and low dayrates.  Changes in commodity prices can have a dramatic effect on rig demand, and periods of excess rig supply may 
intensify competition in the industry and result in the idling of older and less technologically advanced equipment.  We have idled and stacked 
rigs, and may in the future idle or stack additional rigs or enter into lower dayrate drilling contracts in response to market conditions.  Idled 
or stacked rigs may remain out of service for extended periods of time. 

During prior periods of high dayrates and rig utilization rates, we and other industry participants have responded to increased 
customer demand by increasing the supply of rigs through ordering the construction of new units.  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.  Additional rigs that remain under construction, and the entry into service of these new units 
will increase overall supply. 

Our two ultra-deepwater drillships currently under construction have not been contracted for work.  Combined with the expected 
increase in the number of rigs in the global market completing contracts and becoming idle, the number of new units expected to be delivered 
without contracts has intensified and may further intensify price competition.  Any further near-term increase in the construction of new units 
would likely exacerbate the negative impact of increased supply on dayrates and utilization rates.  Additionally, lower market dayrates and 

AR-9 

 
intense price competition may drive customers to seek to renegotiate existing contracts to lower dayrates in exchange for longer contract 
terms.  In an oversupplied market, we may have limited bargaining power to negotiate on more favorable terms.  Lower dayrates and rig 
utilization rates could adversely affect our revenues and profitability. 

(cid:131)  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 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 the current weak commodity 
price environment as operators look to reduce their capital expenditures.  In February 2018, after experiencing equipment breakdown that 
could not be repaired timely, we and our customer mutually agreed to amend the drilling contract for one of our rigs at a reduced dayrate 
and for reduced duration.  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, or 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 statement of financial position, results of operations or 
cash flows.  See “Item 1. Business—Contract Drilling Services.” 

(cid:131)  Our current backlog of contract drilling revenue may not be fully realized. 

At February 19, 2018, our contract backlog was approximately $12.8 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  not  expected  to  be  significant  to  our  contract  drilling 
revenues.    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.  Our 
contractual backlog includes amounts associated with our newbuild units that are currently under construction.  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.  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 
statement of financial position, results of operations or cash flows. 

(cid:131)  We may not be able to renew or obtain new drilling contracts for rigs whose contracts are expiring, cancelled or terminated 

or obtain drilling contracts for 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.  
A number of existing drilling contracts for our drilling rigs that are currently operating are scheduled to expire before December 31, 2018, 
and our two ultra-deepwater drillships currently under construction do not have customer drilling contracts.  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 statement of financial position, results of operations or cash flows. 

AR-10 

 
(cid:131)  We must make substantial capital and operating expenditures to maintain our fleet, and we may be required to make significant 
capital expenditures to maintain our competitiveness and to comply with laws and the applicable regulations and standards 
of governmental authorities and organizations, or to execute our growth plan. 

We must make substantial capital and operating expenditures to maintain our 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.  Our expenditures may also increase as a result of industry standards, 
governmental regulations and maritime self-regulatory organization and technical standards related to safety, security or the environment. 

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.  Changes in governmental regulations, 
safety or other equipment standards, as well as compliance with standards imposed by maritime self-regulatory organizations, may require 
us to make additional unforeseen capital expenditures.  As a result, 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. 

In addition, 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, 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 statements 
of financial condition, results of operations and cash flows. 

(cid:131)  Various credit rating agencies have rated our debt below investment grade, which could limit our access to capital and have 

a materially adverse effect on our business and financial condition. 

Three credit  rating  agencies  have  rated  our  non-credit  enhanced  senior  unsecured  long-term  debt  (“Debt Rating”)  below 

investment grade.  Our Debt Rating levels could have material adverse consequences on our business and future prospects and could: 

(cid:131) 
(cid:131) 

(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 

limit our ability to access debt markets, including for the purpose of refinancing our existing debt or replacing our existing credit agreements; 
cause us to refinance, issue debt or enter into bank credit agreements with less favorable terms and conditions, which debt may require 
collateral and restrict, among other things, our ability to pay distributions or repurchase shares; 
increase certain fees under our credit facilities and interest rates under indentures governing certain of our senior notes; 
negatively impact current and prospective customers’ willingness to transact business with us; 
impose additional insurance, guarantee and collateral requirements; 
limit our access to bank and third-party guarantees, surety bonds and letters of credit; and 
suppliers and financial institutions may lower or eliminate the level of credit provided 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. 

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

effects listed above. 

(cid:131)  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, 2017 and 2016, our total consolidated debt was $7.4 billion and $8.5 billion, respectively.  This substantial level 

of debt and other obligations could have significant adverse consequences on our business and future prospects, including the following: 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

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.”

(cid:131)  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  a  material  adverse  impact  on  our  consolidated  statement  of  financial  position,  results  of 
operations or cash flows. 

We engage in offshore drilling services for most of the leading international oil companies or their affiliates, as well as for many 
government-controlled  oil  companies  and  independent  oil  companies.    For  the  year  ended  December 31,  2017,  our  most  significant 
customers were Chevron, Shell and Petrobras, accounting for approximately 29 percent, 17 percent and 14 percent, respectively, of our 
consolidated operating revenues.  As of February 19, 2018, the customers with the most significant aggregate amount of contract backlog 
were  Shell,  Statoil  and  Chevron,  representing  approximately  52 percent,  31 percent  and  10 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 a material adverse effect on our results of operations and 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 expenses 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 a material adverse effect on our business and on our consolidated statement of financial condition 
results of operations or cash flows. 

(cid:131)  Worldwide financial, economic and political conditions could have a material adverse effect on our consolidated statement of 

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 statement of 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 statement of financial 
position, results of operations or cash flows. 

(cid:131)  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 because portions 
of the crew may be required to prepare rigs for stacking, after which time the crew members may be assigned 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.  Contract preparation 
costs vary based on the scope and length of contract preparation required and the duration of the firm contractual period over which such 
expenditures are amortized.

(cid:131)  Our shipyard projects and operations are subject to delays and cost overruns. 

As of February 19, 2018, we had two ultra-deepwater floater newbuild rigs under construction.  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: 

(cid:131)

(cid:131) 

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 revenue to us, 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. 

(cid:131)  We could experience a material adverse effect on our consolidated statement of financial position, results of operations or 
cash  flows  to  the  extent  the  Macondo well’s  operator  fails  to  indemnify  us  or  is  otherwise  unable  to  indemnify  us  for 
compensatory damages related to the Macondo well incident as required under the terms of our settlement agreement. 

The Macondo well incident resulted in the most extensive spill of hydrocarbons in U.S. history.  Under the Deepwater Horizon 
drilling  contract  and  in  accordance  with  our  settlement  agreement  with  the  operator,  BP plc  (together  with  its  affiliates  “BP”)  agreed  to 
indemnify us with respect to certain matters, and we agreed to indemnify BP with respect to certain matters.  We could experience a material 
adverse effect on our consolidated statement of financial position, results of operations or cash flows to the extent that BP fails to fully satisfy 
its indemnification obligations, including by reason of financial or legal restrictions, or our insurance policies do not fully cover these amounts.  
In addition, in connection with our settlement with the Department of Justice (the “DOJ”), we agreed that we will not use payments pursuant 
to a civil consent decree by and among the DOJ and certain of our affiliates (the “Consent Decree”) as a basis for indemnity or reimbursement 
from non-insurer defendants named in the complaint by the U.S. or their affiliates. 

(cid:131) 

The continuing effects of the enhanced regulations enacted following the Macondo well incident and of agreements applicable 
to us could materially and adversely affect our worldwide operations. 

Following the Macondo well incident, enhanced governmental safety and environmental requirements applicable to both deepwater 
and shallow water 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 previously 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 further 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 of the new inspections, certification requirements 

AR-13 

 
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 a material 
adverse effect on our revenues and profitability. 

(cid:131)  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 statement of 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. 

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.  These governmental approvals 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  could  have  a  material  adverse  effect  on  our  business,  operating  results  or  financial 
condition.    Compliance  with  any  such  new  legislation  or  regulations  could  have  an  adverse  effect  on  our  consolidated  statements  of 
operations and cash flows. 

As  an  operator  of  mobile  offshore  drilling  units  in  some  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.  For example, one of the courts in the litigation related to the Macondo well incident refused to 
enforce aspects of our indemnity with respect to certain environmental-related liabilities.  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 statement of 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. 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. 

A substantial portion of our drilling contracts are partially payable in local currency.  Those amounts may exceed our local currency 
needs, leading to the accumulation of excess local currency, which, in 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. 

An inability to obtain visas and work permits for our employees on a timely basis could impact our operations and have an adverse 
effect on our business.  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 operate our rigs 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 adversely affect our consolidated statement of financial position, results of operations or cash flows. 

AR-15 

 
(cid:131)  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 an additional aggregate annual deductible of $50 million, which is 
self-insured through our wholly-owned captive insurance company.  We also retain the risk for any liability in excess of our $750 million 
excess liability coverage.  However, pollution and environmental risks generally are not completely insurable. 

If  a  significant  accident  or  other  event  occurs  that  is  not  fully  covered  by  our  insurance  or  by  an  enforceable  or  recoverable 
indemnity, the occurrence could adversely affect our consolidated statement of 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. 

(cid:131)  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 retain executive management and members of our board of directors. 

AR-16 

 
(cid:131)  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 
acquisitions, divestitures 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.  For example: 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 
(cid:131) 

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  problems  could  also  arise  in  the  integration  or  separation  processes,  including  unanticipated  restructuring  or  separation 
expenses  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; 
the diversion of management and key employees' attention may detract from our ability to increase revenues and minimize costs; and  
certain transactions may result in other unanticipated adverse consequences. 

(cid:131) 

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. 

(cid:131)  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 26 percent of our total workforce, working primarily in Brazil, Norway and the U.K. are represented by, and some of 
our contracted labor work is subject to, collective bargaining agreements, substantially all of which are subject to annual salary negotiation.  
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.  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. 

(cid:131) 

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,  financial  condition  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 
other third-party 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 from potential customers 
or retain existing business from 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. 

(cid:131)  Regulation of greenhouse gases and climate change could have a negative impact on our business. 

Some scientific studies have suggested that emissions of certain gases, including greenhouse gases, carbon dioxide and methane, 
may be contributing 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. 

AR-17 

 
In the U.S., the U.S. Environmental Protection Agency has begun adopting and implementing a comprehensive suite of regulations 
to restrict emissions of greenhouse gases under existing provisions of the Clean Air Act.  In addition, a number of other federal, state and 
regional efforts have focused on tracking or reducing greenhouse gas emissions.  Efforts have also been made and continue to be made in 
the international community toward the adoption of international treaties or protocols that would address global climate change issues.  In 
December 2015,  the  U.S.  joined  the  international  community  at  the  21st Conference  of  the  Parties  of  the  United  Nations  Framework 
Convention  on  Climate  Change  in  Paris,  France.    The  resulting  agreement  (the  “Paris  Agreement”)  calls  for  the  parties  to  undertake 
“ambitious efforts” to limit the average global temperature and to conserve and enhance sinks and reservoirs of greenhouse gases.  The 
U.S. is one of over 70 nations having ratified or otherwise consented to be bound by the Paris Agreement.  The greenhouse gas emission 
reductions  called  for  by  the  Paris Agreement  are  not  binding.    On  June 1,  2017,  the  U.S.  announced  its  plan  to  withdraw  from  the 
Paris Agreement and to seek negotiations either to reenter the Paris Agreement on different terms or establish a new framework agreement.  
The  Paris Agreement  provides  for  a  four-year  exit  process  beginning  in  November 2016,  which  would  result  in  an  effective  exit-date  of 
November 2020.  The U.S.’s adherence to the exit process is uncertain, and the terms on which the U.S. may reenter the Paris Agreement 
or a separately negotiated agreement if it chooses to do so, are unclear at this time. 

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  a  negative  impact  on  our 
business. 

(cid:131)  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 10—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, a material adverse effect on our financial results and condition could result. 

(cid:131)  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.  Threats to our information technology systems associated with cybersecurity risks and cyber-incidents or 
attacks continue to grow.  In addition, breaches to our systems 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 data; disruption of our customers’ operations; loss or damage to our customer 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, financial condition, cash flows and results of operations. 

(cid:131)  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. 

AR-18 

 
(cid:131)  Public health threats could have a material adverse effect on our operations and our financial results. 

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.  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 operations and adversely affect our financial results. 

Other risks 

(cid:131)  We have significant carrying amounts of long-lived assets that are subject to impairment testing. 

At December 31, 2017, the carrying amount of our property and equipment was $17.4 billion, representing 78 percent of our total 
assets.  In accordance with our critical 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.  In the year ended December 31, 2017, 
we recognized an aggregate loss of $1.4 billion associated with the impairment of certain assets sold for scrap value or for alternative use, 
and we recognized a loss of $94 million associated with the impairment of our midwater floater asset group.  In the year ended December 31, 
2016,  we  recognized  an  aggregate  loss  of  $52 million  associated  with  the  impairment  of  our  deepwater  floater  asset  group,  and  we 
recognized a loss of $41 million associated with the impairment of certain assets sold for scrap value.  Future expectations of lower dayrates 
or rig utilization rates or a significant change to the composition of one or more of our asset groups or to our contract drilling services reporting 
unit could result in the recognition of additional losses on impairment of our long-lived asset groups if future cash flow expectations, based 
upon  information  available  to  management  at  the  time  of  measurement,  indicate  that  the  carrying  amount  of  our  asset  groups  may  be 
impaired. 

(cid:131)  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 tax rate on our worldwide earnings, which could result in a significant 
negative impact on our earnings and cash flows from operations. 

We operate worldwide through our various subsidiaries.  Consequently, we are subject to changes in applicable tax laws, treaties 
or  regulations  in  the  jurisdictions  in  which  we  operate,  which  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. 

The U.S., for example, has enacted tax legislation that eliminates some perceived tax advantages of companies that have legal 
domiciles outside the U.S., but have certain U.S. connections.   Switzerland, in response to certain guidance from and demands by the 
European Union (“EU”) and the Organization for Economic Co-operation and Development (the “OECD”), has been carefully considering 
various tax reform proposals.  Some of these tax reform measures may be adopted into law and effective as early as 2019.  Switzerland’s 
implementation of any material change in tax laws or policies or its adoption of new interpretations of existing tax laws and rulings could 
result in a higher effective tax rate on our worldwide earnings and such change could have a material adverse effect on our consolidated 
statement of financial position, results of operations or cash flows. 

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.  The EU issued its Anti-Tax Avoidance Directive in 2016 that required its member states 
to adopt specific tax reform measures by 2019.  Any material change in tax laws or policies, or their interpretation, resulting from such 
legislative proposals or inquiries could result in a higher effective tax rate on our worldwide earnings and such change could have a material 
adverse effect on our consolidated statement of financial position, results of operations or cash flows. 

Other tax jurisdictions in which we operate may consider implementing similar legislation.  The implementation of such legislation, 
any other material changes in tax laws or policies or the adoption of new interpretations of existing tax laws and rulings could result in a 
higher effective tax rate on our worldwide earnings and any such change could have a material adverse effect on our consolidated statement 
of financial position, results of operations or cash flows. 

(cid:131)  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 tax rate on our worldwide earnings, which 
could result in a significant negative impact on our earnings and cash flows from operations. 

We  are  a  Swiss  corporation  that  operates  through  our  various  subsidiaries  in  a  number  of  countries  throughout  the  world.  
Consequently, we are subject to tax laws, treaties and regulations in and between the countries in which we operate.  Our income taxes are 
based upon 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. 

AR-19 

 
Our income tax returns are subject to review and examination.  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, when applicable, 
that  we  or  any of  our  key  subsidiaries  maintained  or  maintain  a  permanent  establishment  in  the  U.S.,  since,  among  other  things,  such 
determination involves considerable uncertainty.  If we or any of our key subsidiaries were considered to have been engaged in a trade or 
business in the U.S., when applicable, through a permanent establishment, 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, in which case 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. 

(cid:131)  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 the performance of 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.  It should be noted, 
however, that a prior case and an IRS pronouncement which relies on the case characterize income from time chartering of vessels as rental 
income rather than services income for other tax purposes.  However, the IRS subsequently has 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 to be 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 such shareholder, such shareholder generally would be liable 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.    In  addition,  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. 

(cid:131)  We may be limited in our use of net operating losses and tax credits. 

Our ability to benefit from our deferred tax assets depends on us having sufficient future earnings to utilize our net operating loss 
and tax credit carryforwards before they expire.  We have established a valuation allowance against the future tax benefit for a number of 
our U.S. and non U.S. net operating losses and tax credit carryforwards, and we could be required to record an additional valuation allowance 
against other U.S. or non-U.S. deferred tax assets if market conditions change materially and, as a result, our future earnings are, or are 
projected to be, significantly less than we currently estimate.  Our net operating loss and tax credit carryforwards are subject to review and 
potential disallowance upon audit by the tax authorities of the jurisdictions where these tax attributes are incurred. 

(cid:131)  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.  The authorized share capital is limited to a maximum of 50 percent of a company’s registered share 
capital and is subject to re-approval by shareholders every two years.  Shareholders at our annual general meeting in May 2018 will be 
requested  to  approve  an  authorized  share  capital  since  the  current  authorized  share  capital  will  expire  on  May 12,  2018.    Our  current 

AR-20 

 
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 on the repurchase price less the par value to the extent attributable to 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.  We may repurchase shares under the share repurchase program using a procedure pursuant to which 
we can repurchase shares under the share repurchase program via a “virtual second trading line” from market players, in particular, banks 
and institutional investors, who are generally entitled to receive a full refund of the Swiss withholding tax.  Our ability to use the “virtual 
second trading  line”  is  limited  to  the  share  repurchase  program  currently  approved  by  our  shareholders,  and  any  use  of  the  “virtual 
second trading line” with respect to future share repurchase programs will require the approval of the competent Swiss tax 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. 

(cid:131)  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 in these circumstances 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.

(cid:131)  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.  These provisions may also adversely affect prevailing market prices for our shares.  These

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 the current authorized share capital of the Company will expire on May 12, 2018, to issue a specified number 
of shares, which under the current authorized share capital of the Company 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 
31  percent of the share capital registered in the commercial register as of February 13, 2018 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 advance notice is given to the company; 
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 “cashout” or “squeezeout” 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. 

(cid:131) 

The results of the U.K.’s referendum on withdrawal from the European Union may have a negative effect on global economic 
conditions, financial markets and 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.  Nevertheless, the referendum has created 
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 a material adverse effect on global 
economic 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 statement of financial position, results 
of operations or cash flows.

Legal Proceedings 

We have certain actions, claims and other matters pending as discussed and reported in “Part II. Item 8. Financial Statements and 
Supplementary  Data—Notes  to  Consolidated  Financial  Statements—Note 10—Commitments  and  Contingencies”  and  “Part II.  Item 7. 
Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contingencies and Uncertainties—” in this annual 
report  for  the  year  ended  December 31,  2017.    We  are  also  involved  in  various  tax  matters  as  described  in  “Part II.  Item 8.  Financial 
Statements  and  Supplementary  Data—Notes  to  Consolidated  Financial  Statements—Note 6—Income  Taxes”  and  in  “Part II.  Item 7.

Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contingencies and Uncertainties—Tax matters” 
in this annual report for the year ended December 31, 2017.  All such actions, claims, tax and other matters are incorporated herein by 
reference. 

As of December 31, 2017, we were also involved in a number of other lawsuits, claims and disputes, which have arisen in the 
ordinary  course  of  our  business  and  for  which  we  do  not  expect  the  liability,  if  any,  to  have  a  material  adverse  effect  on  our  current 
consolidated statement of financial position, results of operations or cash flows.  We cannot predict with certainty the outcome or effect of 
any of the matters referred to above or of any such other pending or threatened litigation or legal proceedings.  There can be no assurance 
that our beliefs or expectations as to the outcome or effect of any lawsuit or claim or dispute will prove correct and the eventual outcome of 
these matters could materially differ from management’s current estimates. 

In addition to the legal proceedings described above, we may from time to time identify other matters that we monitor through our 
compliance program and in response to events arising generally within our industry and in the markets where we do business.  For example, 
in  the  year  ended  December 31,  2015,  we  began  investigating  statements  made  by  a  former  employee  of  Petróleo  Brasileiro S.A. 
(“Petrobras”) related to the award to us of a drilling services contract in Brazil.  These statements were made in connection with an ongoing 
criminal investigation by the Brazilian authorities into Petrobras and certain other companies and individuals.  We completed our internal 
investigation, and we did not identify any wrongdoing by any of our employees or agents in connection with our business.  We voluntarily 
met with governmental authorities in the U.S. to discuss the statements made by the former Petrobras employee and our internal investigation 
as well as our findings.  We will continue to investigate these types of allegations and cooperate with governmental authorities.  Through the 
process of monitoring and proactive investigation, we strive to ensure no violation of our policies, Code of Integrity or law has, or will, occur; 
however, there can be no assurance as to the outcome of these matters.

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 0.5% 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.  By 
March 31, 2018, we expect to complete the acquisition of the remaining shares not owned by us through a compulsory acquisition of the 
remaining shares not owned by us, which is available to us under Cyprus law.  In connection with the acquisition, we issued 66.9 million 
shares to shareholders of Songa with an aggregate market value of $735 million, equivalent to $10.99 per share, estimated based on the 
market value of our shares on the date of issuance.  We also issued an aggregate principal amount of $854 million of the Exchangeable 
Bonds 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.  See 
“Part II. Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements and 20(cid:326)Subsequent Event.” 

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

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

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

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

Swiss withholding tax 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, 2017, the aggregate amount of par value of our outstanding 
shares was CHF 39 million, equivalent to approximately $40 million, and the aggregate amount of qualifying additional paid-in capital of our 
outstanding shares was CHF 11.4 billion, equivalent to approximately $11.7 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 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 the 35 percent Swiss 
withholding tax.  However, for shares repurchased for capital reduction, the portion of the repurchase price attributable to the par value of 
the shares repurchased will not be subject to the Swiss withholding tax.  Since January 1, 2011, the portion of the repurchase price that is 
according to Swiss tax law and practice attributable to the qualifying additional paid-in capital for Swiss statutory reporting purposes of the 
shares repurchased will also not be subject to the Swiss withholding tax.  We would be required to withhold at such rate the tax from the 
difference between the repurchase price and the related amount of par value and, since January 2011, 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. 

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.  Currently, our ability to use the “virtual second trading line” will be limited to the share repurchase program currently 
approved by our shareholders, and any use of the “virtual second trading line” with respect to future share repurchase programs will require 
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, will generally not be subject to Swiss withholding tax. 

AR-27 

 
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 13,  2018,  Transocean Inc.,  our  wholly  owned  subsidiary,  held  as  treasury  shares 
approximately  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 amount of shares held as treasury 
shares,  approximately  nine percent  of  our  issued  shares  could  be  repurchased  for  purposes  of  retention  as  additional  treasury  shares.  
Although our board of directors has not approved such a share repurchase program for the purpose of retaining repurchased shares as 
treasury shares, if it did so, any such shares repurchased would be in addition to any shares repurchased under the currently approved 
program.

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.  Following authorization by the board of directors, 
management repurchased and subsequently cancelled 2,863,267 of our shares for an aggregate cost of $240 million, equivalent to an aggregate cost 
of CHF 257 million or an average cost of $83.74 per share.  At December 31, 2017, 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,  at  any  time.    See  “Item 7.

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 a wholly owned indirect subsidiary of Transocean Ltd.  
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.

Item 7. 

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 19, 
2018, we owned or had partial ownership interests in and operated 47 mobile offshore drilling units, including 27 ultra-deepwater floaters, 
12 harsh environment floaters, two deepwater floaters and six midwater floaters.  Additionally, we operated two high-specification jackups 
that were under contract when we sold the rigs, and we continue to operate such rigs until completion or novation of the respective drilling 
contracts.  At February 19, 2018, we also had two ultra-deepwater drillships under construction or under contract to be constructed. 

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.  We believe 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 combination—On January 30, 2018, we completed our acquisition of 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”).  
By March 31, 2018, we expect to complete the acquisition of the remaining shares not owned by us through a compulsory acquisition, which 
is available to us under Cyprus law.  In connection with 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.” 

Fleet  expansion—In  February 2018,  we  completed  the  construction  of  and  placed  into  service  the  ultra-deepwater  floater 
Deepwater Poseidon.  During the year ended December 31, 2017, we completed construction of and placed into service the ultra-deepwater 
floater Deepwater Pontus.  See “—Operating Results” and “—Liquidity and Capital Resources—Drilling fleet.” 

Drilling contract terminations—In the year ended December 31, 2017, we recognized revenues of $201 million and received 
aggregate cash proceeds of $408 million associated with early terminated or cancelled drilling contracts.  See “—Outlook,” “—Operating 
Results” and “—Liquidity and Capital Resources—Sources and uses of cash.” 

Dispositions—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  the 
transaction, we received aggregate net cash proceeds of $319 million and recognized an aggregate net loss of $1.6 billion associated with 
the disposal of these assets. 

During the year ended December 31, 2017, we completed the sale of one ultra-deepwater and three midwater floaters, along with 
related equipment, for which we received aggregate net cash proceeds of $22 million, and recognized an aggregate net gain of $9 million.  
See “—Liquidity and Capital Resources—Drilling fleet.” 

Impairments—During the year ended December 31, 2017, we recognized a loss of $1.4 billion associated with the impairment of 
five ultra-deepwater floaters, one deepwater floater and two midwater floaters, along with related assets, which were classified as held for 
sale at the time of impairment. 

In the year ended December 31, 2017, as a result of impairment testing, we determined that our midwater floater asset group was 
impaired, and we recognized a loss of $94 million, associated with the impairment of these held and used assets.  See “—Operating Results”, 
“—Liquidity and Capital Resources—Drilling fleet”. 

Debt  issuances—On  October 17,  2017,  we  completed  an  offering  of  an  aggregate  principal  amount  of  $750 million  of 
7.50% senior unsecured notes due January 2026 (the “7.50% Senior Notes”), and we received aggregate cash proceeds of $742 million, 
net of issue costs.  On May 5, 2017, we completed an offering of an aggregate principal amount of $410 million of 5.52% senior secured 
notes due May 2022 (the “5.52% Senior Secured Notes”), and we received aggregate cash proceeds of $403 million, net of issue costs.  See 
“—Liquidity and Capital Resources—Sources and uses of liquidity.” 

AR-30 

 
Debt tender offers—On July 11, 2017, we completed cash tender offers (the “2017 Tender Offers”) to purchase 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.  As a result, we made an aggregate cash payment of $1.3 billion and recognized an aggregate 
net loss of $48 million associated with the retirement of such validly tendered debt.  See “—Liquidity and Capital Resources—Sources and 
uses of liquidity.” 

Debt  redemptions  and  repurchases—During  the  year  ended  December 31,  2017,  we  completed  transactions  to  redeem  or 
repurchase an aggregate principal amount of $557 million of our debt securities.  As a result, we made an aggregate cash payment of 
$564 million and recognized an aggregate net loss of $7 million associated with the retirement of such redemptions and repurchases of debt.  
See “—Liquidity and Capital Resources—Sources and uses of liquidity”. 

Outlook 

Drilling  market—Our  long-term  view  of  the  offshore  drilling  market  remains  positive,  especially  for  harsh  environment  and 
ultra-deepwater floaters.  Brent oil prices have exceeded $70 per barrel for the first time since 2015, improving our customers’ economics of 
drilling oil and gas wells.  This is, in large part, due to favorable trends in the hydrodcarbon supply-demand balance where oil supply has 
declined relative to demand. 

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 
is resulting 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.  However, 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. 

As of February 19, 2018, our contract backlog, including the contract backlog recently acquired in the Songa acquisition, was 
$12.8 billion  compared  to  $9.4 billion  as  of  October 26,  2017.    The  risks  of  drilling  project  delays,  contract  renegotiations  and  contract 
terminations and cancellations remain in the near term. 

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 19, 2018, the uncommitted fleet rates for each of the five years in the period ending December 31, 2022 were as 

follows: 

Uncommitted fleet rate 
Ultra-deepwater floaters
Harsh environment floaters

Performance and Other Key Indicators 

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  and  contract  preparation  or  other  incentive 
provisions, 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.

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 acquisition of Songa, 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. 

The  contract  backlog  for  high-specification  floaters  represents  the  backlog  for  two high-specification  jackups  that  were  under 

contract when we sold the rigs, and we continue to operate such rigs until completion or novation of the respective drilling contracts. 

In February 2018, after experiencing equipment breakdown that could not be repaired timely, we and our customer mutually agreed 
to  amend  the  drilling  contract  for  Transocean Leader  at  a  reduced  dayrate  and  for  reduced  duration,  which  resulted  in  the  removal  of 
approximately  $112 million  from  the  contract  backlog  for  harsh  environment  floaters,  as  presented  above.    During  the  year  ended 
December 31, 2017, a customer early terminated for convenience its drilling contract for  Discoverer Clear Leader, which resulted in the 
removal of approximately $202 million from the contract backlog for our ultra-deepwater floaters, as presented above.  During the year ended 
for  Deepwater Asgard,  Deepwater Champion, 
terminated  or  cancelled  contracts 
December 31,  2016,  our  customers  early 
Deepwater Millennium, 
and 
Transocean John Shaw.

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.  At February 19, 2018, the contract backlog for the high-specification jackups 
represents  the  contract  backlog  associated  with  the  contracted  revenues  we  expect  to  earn  for  the  continued  operation  of 
two high-specification jackups following the sale of these rigs.  See “—Operating Results” and “—Liquidity and Capital Resources—Drilling

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.

Average daily revenue—Average daily revenue is defined as contract drilling revenues earned per operating day.  An operating 
day is defined as a calendar day during which a rig is contracted to earn a dayrate during the firm contract period after commencement of 
operations.  The average daily revenue for our fleet was as follows:

Our average daily revenue fluctuates relative to market conditions and our revenue efficiency.  The average daily revenue may 
also be affected by revenues for lump sum bonuses or demobilization fees received from our  customers.  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, 
classification as held for sale, except when we continue to operate rigs subsequent to sale, as we do with two of the high-specification 
jackups sold in May 2017. 

Average daily revenue decreased for the year ended December 31, 2017 relative to the prior years due to the completion of drilling 

contracts with higher dayrates and the commencement of newly signed drilling contracts at substantially lower dayrates. 

Revenue efficiency—Revenue efficiency is defined as actual contract drilling revenues for the measurement period divided by 
the maximum revenue calculated for the measurement period, expressed as a percentage.  Maximum revenue is defined as the greatest 
amount of contract drilling revenues the drilling unit could earn for the measurement period, excluding 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.

Operating 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 
(a) approximately $325 million resulting from our four newbuild ultra-deepwater drillships that commenced operations during 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 
$196 million resulting from drilling contracts early terminated or cancelled by our customers, and by $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: 
(a) approximately $75 million resulting from our four newbuild ultra-deepwater drillships that commenced operations during 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  approximately 
$50 million  primarily  resulting  from  our  newbuild  ultra-deepwater  drillships  placed  into  service  during  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 a loss on impairment related 
to the following: (a) a loss of $1.4 billion associated with the impairment of certain assets to be sold for scrap value or for alternative use, 
which were classified as held for sale at the time of impairment, and (b) a loss of $94 million associated with the impairment of our midwater 
floater  asset  group.    In  the  year  ended  December 31,  2016,  we  recognized  a  loss  on  impairment  related  to  the  following:  (a) a  loss  of 
$52 million associated with the impairment of our deepwater floater asset group and (b) a loss of $41 million associated with the impairment 
of certain assets classified as held for sale. 

Loss  on  disposal  of  assets  in  the  year  ended  December 31,  2017,  was  primarily  the  result  of  the  completion  of  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 
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  (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 $33 million of reduced income associated with our dual-activity patent. 

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 from continuing operations 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 was 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 United States (“U.S.”) deferred tax 
assets for a tax rate change as a result of the 2017 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 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 from continuing operations 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 (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. 

In December 2017, the U.S. enacted the 2017 Tax Act, which includes a number of changes to existing U.S. tax laws that have an 
impact on our income tax provision, most notably a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent for tax 
years beginning after December 31, 2017, and the creation of a territorial tax system with a one-time mandatory tax on certain unremitted 
earnings and profits of the foreign subsidiaries of our U.S. subsidiaries.  The 2017 Tax Act also makes prospective changes beginning in 
2018, including a base erosion and anti-abuse tax (“BEAT”), a global intangible low-taxed income tax, additional limitations on the deductibility 
of executive compensation, limitations on the deductibility of interest, and repeal of the domestic manufacturing deduction.  As a result of the 
2017 Tax  Act,  we  remeasured  our  deferred  tax assets  and  liabilities  to  reflect  the  reduction  in  the  U.S.  corporate  income  tax  rate  from 
35 percent  to  21 percent,  resulting  in  a  $66 million  increase  in  income  tax  expense  for  the  year  ended  December 31,  2017  and  a 
corresponding  $66 million  decrease  in  net  deferred  tax  assets  as  of  December 31,  2017.    We  are  still  analyzing  certain  aspects  of  the 
2017 Tax Act and refining our calculations which could potentially affect the measurement of these balances or potentially give rise to new 
deferred tax amounts. 

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 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 a number of 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 

AR-35 

 
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 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.

Operating revenues—Contract drilling revenues decreased for the year ended December 31, 2016 compared to the year ended 
December 31, 2015 primarily due to the following: (a) approximately  $2.2 billion resulting from a greater number of rigs idle or stacked, 
(b) approximately $860 million resulting from rigs sold or classified as held for sale and (c) approximately $365 million resulting from lower 
dayrates.  These decreases were partially offset by (a) approximately $270 million resulting from our newbuild ultra-deepwater drillships that 
commenced operations in the year ended December 31, 2016 and (b) approximately $70 million resulting from improved revenue efficiency. 

Other revenues decreased for the year ended December 31, 2016 compared to the year ended December 31, 2015, primarily due 
to approximately $91 million resulting from reimbursable items and approximately $37 million resulting from drilling contracts early terminated 
or cancelled by our customers. 

Costs  and  expenses—Excluding  the  income  effect  of  $30 million  and  $788 million  of  cost  reimbursements  from  settlements, 
recoveries  from  insurance  and  net  adjustments  to  contingent  liabilities  associated  with  the  Macondo well  incident  in  the  years  ended 
December 31,  2016  and  2015,  respectively,  operating  and  maintenance  expense  decreased  for  the  year  ended  December 31,  2016 
compared  to  the  year  ended  December 31,  2015,  by  approximately  $1.8 billion.    This  decrease  was  primarily  due  to  the  following: 
(a) approximately $1.04 billion resulting from a greater number of rigs idle or stacked, (b) approximately $355 million resulting from rigs sold 
or classified as held for sale, (c) approximately $315 million resulting from reduced offshore costs and (d) approximately $195 million resulting 
from reduced onshore costs.  These decreases were partially offset by approximately $75 million resulting from our newbuild ultra-deepwater 
drillships that commenced operations in the year ended December 31, 2016.

Depreciation expense decreased for the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily 
due to the following: (a) approximately $87 million resulting from the impairment of our deepwater floater and midwater floater asset groups 
in the prior year and (b) approximately $40 million resulting from rigs sold or classified as held for sale, partially offset by (c) approximately 
$66 million resulting from our newbuild ultra-deepwater drillships and other property and equipment placed into service in the year ended 
December 31, 2016. 

General and administrative expense decreased for the year ended December 31, 2016 compared to the year ended December 31, 
2015 primarily due to the following: (a) approximately $22 million of reduced personnel costs, (b) approximately $8 million of reduced rental 
expense, partially offset by (c) approximately $9 million of increased professional fees. 

Loss on impairment and disposals—In the year ended December 31, 2016, we recognized a loss on impairment due to the 
following: (a) a loss of $52 million associated with the impairment of our deepwater floater asset group and (b) a loss of $41 million associated 
with the impairment of certain assets classified as held for sale.  In the year ended December 31, 2015, we recognized a loss on impairment 
due to the following: (a) an aggregate loss of $700 million associated with the impairment of certain assets classified as held for sale, (b) a 
loss of $668 million associated with the impairment of our midwater floater asset group and (c) a loss of $507 million associated with the 
impairment of our deepwater floater asset group. 

In the year ended December 31, 2016, we recognized an aggregate net loss associated with the disposal of three deepwater 
floaters and eight midwater floaters, along with related equipment, and other assets.  In the year ended December 31, 2015, we recognized 
an aggregate net loss associated with the disposal of two ultra-deepwater floaters, six deepwater floaters and nine midwater floaters, along 
with related equipment, and other assets. 

Other income and expense—Interest expense, net of amounts capitalized, decreased in the year ended December 31, 2016 
compared  to  the  year  ended  December 31,  2015,  primarily  due  to  the  following:  (a) approximately  $98 million  resulting  from  our  debt 
repurchases and redemptions and (b) approximately $36 million of increased interest capitalized resulting from our newbuild construction 
program.  Partially offsetting these decreases were the following: (a) approximately $64 million resulting from new debt issued in the year 
ended December 31, 2016 and (b) approximately $37 million resulting from downgrades to the credit rating for our senior unsecured long-
term debt. 

In the year ended December 31, 2016, we recognized net gains due to the following: (a) an aggregate gain of $104 million resulting 
from the completion of our 2016 Tender Offers and (b) an aggregate net gain of $44 million resulting from the redemption or repurchase of 
$399 million aggregate principal amount of our debt securities.  In the year ended December 31, 2015, we recognized a net gain due to the 
following: (a) an aggregate net gain of $33 million resulting from our repurchases of $503 million aggregate principal amount of our debt 
securities partially offset by (b) an aggregate loss of $10 million resulting from the redemption of $893 million aggregate principal amount of 
the 4.95% senior notes due November 2015 (the “4.95% Senior Notes”). 

Income tax expense—In the years ended December 31, 2016 and 2015, our effective tax rate was 11.5 percent and 11.9 percent, 
respectively, based on income from continuing operations before income tax expense.  In the years ended December 31, 2016 and 2015, 
the effect of the various discrete period tax items was a net tax benefit of $50 million and $75 million, respectively.  In the years ended 
December 31, 2016 and 2015, our effective tax rate, excluding discrete items, was 18.5 percent and 14.4 percent, respectively, based on 
income from continuing operations before income tax expense.  Our effective tax rate, excluding discrete items, increased in the year ended 
December 31, 2016 compared to the year ended December 31, 2015, primarily due to (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. 

Due to a number of 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, 2016, 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.  Conversely, the countries in which we incurred the most significant income taxes during this period that 
were based on income before income tax include Norway, Switzerland, 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  —Critical  Accounting  Policies  and 
Estimates—Income taxes.

Liquidity and Capital Resources 

Sources and uses of cash 

At December 31, 2017, we had $2.5 billion in unrestricted cash and cash equivalents and $450 million in unrestricted short-term 
investments.  In the year ended December 31, 2017, our primary sources of cash were our cash flows from operating activities, including 
cash proceeds from customers for early terminations or cancellations of drilling contracts; net proceeds from the issuance of debt and net 
proceeds from the sale of the high-specification jackups.  Our primary uses of cash were the repayment of debt, primarily related to the 
2017 Tender  Offers,  debt  redemptions  and  open  market  debt  repurchases,  our  investments  in  capital  expenditures  and  deposits  into 
short-term investments.

Net cash used in investing activities decreased primarily due to: (a) reduced capital expenditures, primarily associated with our 
newbuild construction projects, and (b) increased proceeds from asset disposals, primarily related to the sale of 10 high-specification jackups 
and the novation of contracts relating to the construction of five high-specification jackups, together with related assets, in the year ended 
December 31, 2017.  These decreases were partially offset by the use of cash associated with deposits into short-term investments, primarily 
time deposits, in the year ended December 31, 2017 with no comparable activity in the prior year.

Sources and uses of liquidity 

Overview—We expect to use existing unrestricted cash balances and short-term investments, internally generated cash flows, 
borrowings under our existing bank credit agreement, 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.  During the year ended December 31, 2015, three credit rating agencies downgraded the rating of our non-credit enhanced senior 
unsecured long-term debt (“Debt Rating”) to Debt Ratings that are below investment grade.  During the years ended December 31, 2016 
and 2017, the same three credit rating agencies further downgraded our Debt Rating.  Such downgrades have caused us to experience 
increased fees under our credit facility 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.  Should the 
drilling market deteriorate, or should we 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 combination—On January 30, 2018, we completed the acquisition of an approximate 97.7 percent ownership interest 
in  Songa.    By  March 31,  2018,  we  expect  to  complete  the  acquisition  of  the  remaining  shares  not  owned  by  us  through  a  compulsory 
acquisition, which is available to us under Cyprus law. 

In connection with the acquisition, we issued 66.9 million shares with an aggregate market value of $735 million, equivalent to 
$10.99 per  share,  estimated  based  on  the  market  value  of  our  shares  on  the  date  of  issuance  to  shareholders  of  Songa  as  partial 
consideration for the acquired Songa shares.  We expect to issue 1.7 million shares for the remaining shares to be acquired through the 
compulsory acquisition. 

We also issued an aggregate principal amount of $854 million of the 0.5% Exchangeable Senior Bonds due January 2023 (the 
“Exchangeable Bonds”) as partial consideration for the acquisition of the acquired Songa shares and partial settlement of certain Songa 
indebtedness.  We expect to issue an aggregate principal amount of $14 million of the Exchangeable Bonds for the remaining shares to be 
acquired through the compulsory acquisition.  Transocean Inc. is the issuer of the Exchangeable Bonds, which are fully and unconditionally 
guaranteed by Transocean Ltd. and rank equally with our other senior unsecured debt.  We will pay interest on the Exchangeable Bonds 
semiannual, commencing July 30, 2018.  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. 

Debt  issuances—On  October 17,  2017,  we  completed  an  offering  of  an  aggregate  principal  amount  of  $750 million  of  the 
7.50% Senior Notes, and we received aggregate cash proceeds of $742 million, net of issue costs.  We used the majority of the net proceeds 
from the debt offering to repay or redeem certain maturing debt.  See “—Debt redemptions and repurchases”) 

On May 5, 2017, we completed an offering of an aggregate principal amount of $410 million of the 5.52% Senior Secured Notes 
and we received aggregate cash proceeds of $403 million, net of issue costs.  The indenture 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. 

On October 19, 2016 and December 8, 2016, we completed an offering of an aggregate principal amount of $600 million of the 
7.75% Senior Secured Notes and $625 million of the 6.25% Senior Secured Notes, respectively, and we received aggregate cash proceeds 
of $583 million and $609 million, respectively, net of initial discount and costs payable by us.  The indentures that govern the 7.75% Senior 
Secured  Notes  and  the  6.25% Senior  Secured  Notes  contain  covenants  that  limit  the  ability  of  our  subsidiaries  that  own  or  operate 
Deepwater Thalassa and Deepwater Proteus to declare or pay dividends to affiliates and impose a maximum collateral rig leverage ratio 
(“Maximum Collateral Ratio”), represented by each rig’s earnings relative to the debt balance, that changes over the terms of the notes.  At 
December 31, 2016, the Maximum Collateral Ratio under both indentures was 5.75:1.00, and the collateral leverage ratio of each subsidiary 
was less than 5.00:1.00. 

AR-39 

 
On July 21, 2016, we completed an offering of an aggregate principal amount of $1.25 billion of the 9.00% Senior Notes, and we 
received aggregate cash proceeds of $1.21 billion, net of initial discount and costs payable by us.  We used the majority of the net proceeds 
from the debt offering to complete the 2016 Tender Offers (see “—Debt tender offers”). 

Debt tender offers—On July 11, 2017, we completed the 2017 Tender Offers to purchase for cash up to $1.5 billion aggregate 
principal amount of the 2017 Tendered Notes.  As a result, we received valid tenders from holders of an aggregate principal amount of 
$1.2 billion of the 2017 Tendered Notes, and we made an aggregate cash payment of $1.3 billion to settle the 2017 Tendered Notes. 

On August 1, 2016, we completed the 2016 Tender Offers to purchase for cash up to $1.0 billion aggregate principal amount of 
certain of our outstanding senior notes (collectively, the “2016 Tendered Notes”).  As a result of the 2016 Tender Offers, we received valid 
tenders from holders of an aggregate principal amount of $981 million of the 2016 Tendered Notes, and we made an aggregate cash payment 
of $876 million to settle the 2016 Tendered Notes. 

Debt redemptions and repurchases—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, by making an 
aggregate cash payment of $407 million using proceeds from the issuance of the 7.50% Senior Notes. 

In  the  years ended  December 31,  2017  and  2016,  we  repurchased  in  the  open  market  an  aggregate  principal  amount  of 
$156 million  and  $399 million,  respectively,  of  our  debt  securities  for  an  aggregate  cash  payment  of  $157 million  and  $354 million, 
respectively.  During the year ended December 31, 2015, we redeemed the remaining aggregate principal amount of $893 million of the 
4.95% Senior Notes for an aggregate cash payment of $904 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.  On the 
scheduled maturity date of December 15, 2016, we made a cash payment of $938 million to repay the outstanding 5.05% Senior Notes due 
December 2016, at a price equal to 100 percent of the aggregate principal amount. 

Distributions of qualifying additional paid-in capital—In May 2015, at our annual general meeting, our shareholders approved 
the distribution  of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $0.60 per outstanding share, 
payable in four quarterly installments of $0.15 per outstanding share, subject to certain limitations.  In May 2015, we recognized a liability of 
$218 million for the distribution payable, recorded in other current liabilities, with a corresponding entry to additional paid-in capital.  On 
June 17 and September 23, 2015, we paid the first two installments in the aggregate amount of $109 million to shareholders of record as of 
May 29, and August 25, 2015.  On October 29, 2015, at our extraordinary general meeting, our shareholders approved the cancellation of 
the third and fourth installments of the distribution. 

In May 2014, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in 
the form of a U.S. dollar denominated dividend of $3.00 per outstanding share, payable in four quarterly installments, subject  to certain 
limitations.    On  March 18,  2015,  we  paid  the  final  installment  in  the  aggregate  amount  of  $272 million  to  shareholders  of  record  as  of 
February 20, 2015. 

We did not pay the distribution of qualifying additional paid-in capital with respect to our shares held by our subsidiary or previously 

held in treasury. 

Litigation settlements and insurance recoveries—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, to resolve (1) punitive damages claims of private plaintiffs, businesses, and local governments 
and (2) certain claims that an affiliate of BP plc. together with its affiliates (“BP”) had made against us and had assigned to private plaintiffs 
who  previously  settled  economic  damages  claims  against  BP.    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  escrow  accounts 
established by the MDL Court for the settlement.  In November 2017, the MDL Court released $25 million from the escrow accounts for 
partial payment of attorneys’ fees.  As of February 13, 2018, the aggregate cash balance of our escrow accounts was $212 million. 

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 to the National Fish & Wildlife Foundation and $150 million to the National Academy of Sciences in 
scheduled installments through February 2017.  In each of the years ended December 31, 2017 and 2016, we made the final scheduled 
cash payments of $60 million. 

Noncontrolling interest—In the year ended December 31, 2016, Transocean Partners LLC (“Transocean Partners”) declared 
and paid an aggregate distribution of $99 million, of which $28 million was paid to holders of noncontrolling interest.  On December 9, 2016, 
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 a wholly owned indirect subsidiary of Transocean Ltd.  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. 

AR-40 

 
Revolving credit facility—In June 2014, we entered into an amended and restated bank credit agreement, which established a 
$3.0 billion  unsecured  five-year  revolving  credit  facility,  that  is  scheduled  to  expire  on  June 28,  2019  (the  “Five-Year  Revolving  Credit 
Facility”).    Among  other  things,  the  Five-Year  Revolving  Credit  Facility  includes  limitations  on  creating  liens,  incurring  subsidiary  debt, 
transactions with affiliates, sale/leaseback transactions, mergers and the sale of substantially all assets.  The Five-Year Revolving Credit 
Facility  also  includes  a  covenant  imposing  a  maximum  consolidated  indebtedness  to  total  tangible  capitalization  ratio  of  0.6 to 1.0.    At 
December 31, 2017, our consolidated indebtedness to total tangible capitalization ratio, as defined in the Five-Year Revolving Credit Facility, 
was 0.4 to 1.0.  In order to borrow or have letters of credit issued under the Five-Year Revolving Credit Facility, we must, at the time of the 
borrowing request, not be in default under the bank credit agreements and make certain representations and warranties, including with 
respect to compliance with laws and solvency, to the lenders, but we are not required to make any representation to the lenders as to the 
absence of a material adverse effect.  Repayment of borrowings under the Five-Year Revolving Credit Facility is 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 Five-Year Revolving Credit Facility and, if not waived by the lenders, could 
cause  us  to  lose  access  to  the  Five-Year  Revolving  Credit  Facility.    See  Notes  to  Consolidated  Financial  Statements—Note 10—
Commitments and Contingencies. 

We may borrow under the Five-Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate (“LIBOR”) 
plus a margin (the “Five-Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the Debt Rating, 
or (2) the base rate specified in  the credit agreement plus the Five-Year Revolving Credit Facility Margin, less one percent per annum.  
Throughout the term of the Five-Year Revolving Credit Facility, we pay a facility fee on the daily unused amount of the underlying commitment 
which ranges from 0.15 percent to 0.35 percent based on our Debt Rating.  At February 13, 2018, based on our Debt Rating on that date, 
the Five-Year Revolving Credit Facility Margin was 2.0 percent and the facility fee was 0.35 percent.  At February 13, 2018, we had no 
borrowings outstanding, $7 million of letters of credit issued, and $3.0 billion of available borrowing capacity under the Five-Year Revolving 
Credit Facility. 

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 December 31, 
2017,  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  upon  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 upon 
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. 
In the years ended December 31, 2017 and 2016, we entered into 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, 2017, our defined benefit pension and other postemployment plans represented an aggregate liability of $359 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 “—Pension and Other Postemployment Benefit Plans” 
and Notes to Consolidated Financial Statements—Note 9—Postemployment Benefit Plans. 
As of December 31, 2017, our unrecognized tax benefits related to uncertain tax positions, net of prepayments, represented a liability of $309 million.  
Due to the 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 have excluded this amount 
from the contractual obligations presented in the table above.  See Notes to Consolidated Financial Statements—Note 6—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 uncommitted credit lines, some of which require cash collateral.  At December 31, 2017, the aggregate cash 
collateral held by banks for letters of credit was $7 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, 2017, 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 investments of the captive insurance company may be limited due to local regulatory restrictions.  At December 31, 2017, the cash 
investments held by the captive insurance company totaled $239 million, and the amount of such cash investments is expected to range 
from $100 million to $250 million by December 31, 2018.  The amount of actual cash investments held by the captive insurance company 
varies, depending on the amount of premiums paid to the captive insurance company, the timing and amount of claims paid by the captive 
insurance company, and the amount of 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 January 30, 2018, we completed our acquisition of an approximate 97.7 percent ownership interest in Songa.  By March 31, 
2018, we expect to complete the acquisition of the remaining shares not owned by us through a compulsory acquisition, which is available 
to us under Cyprus law.  In connection with the acquisition, we acquired seven mobile offshore drilling units, including five harsh environment 
floaters and two midwater floaters.  See Notes to Consolidated Financial Statements—Note 20—Subsequent Event. 

In the years ended December 31, 2017 and 2016, we made capital expenditures of $497 million and $1.3 billion, respectively, 
including $397 million and $1.2 billion, respectively, for our major construction projects.  For the year ending December 31, 2018, we expect 
total  capital  expenditures  and  other  capital  additions  to  be  approximately  $130 million,  including  $74 million  for  our  major  construction 
projects.  As of December 31, 2017, the historical and projected capital expenditures and other capital additions, including capitalized interest, 
for our ongoing major construction projects were as follows: 

Deepwater Pontus (a) 
Deepwater Poseidon (b) 
Ultra-Deepwater drillship TBN1 (c)

In October 2017, the ultra-deepwater floater Deepwater Pontus was placed into service and commenced operations. 
In February 2018, the ultra-deepwater floater Deepwater Poseidon was placed into service and commenced operations. 

(a) 
(b) 
(c)  Our two unnamed ultra-deepwater drillships under construction at the Jurong Shipyard Pte Ltd. in Singapore do not yet have drilling contracts and are 
expected to be delivered in the second quarter of 2020 and the fourth quarter of 2020, respectively.  The delivery expectations and the cost projections 
presented above reflect the terms of our construction agreements, as amended to delay delivery in consideration of current market conditions. 

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 commercial banks or capital 
market financings.  We also have available credit under the Five-Year Revolving Credit Facility, which is expected to be extended or replaced 
with another credit facility before expiration of the underlying bank credit agreement on June 28, 2019 (see “—Sources and uses of liquidity—
Five-Year Revolving Credit Facility”).  Economic conditions could impact the availability of these sources of funding. 

Dispositions—From time to time, we may also 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, 2017, 2016 and 2015, we identified seven, seven and 22 such drilling units, respectively, that we have sold or intend to sell 
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. 

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  $319 million.    During  the  year ended  December 31,  2017,  we  also  completed  the  sale  of 
one ultra-deepwater floater and three midwater floaters, along with related assets, and we received net cash proceeds of $22 million.  During 
the year ended December 31, 2016, we completed the sale of three deepwater floaters and eight midwater floaters, along with related assets, 
and  we  received  aggregate  net  cash  proceeds  of  $22 million.    During  the  year  ended  December 31,  2015,  we  completed  the  sale  of 
two ultra-deepwater floaters, six deepwater floaters and nine midwater floaters, along with related assets, and we received aggregate net 
cash proceeds of $35 million.

Pension and Other Postemployment Benefit Plans 

Overview—As of December 31, 2017, we maintained three funded and three unfunded defined benefit plans in the U.S. (the “U.S. 
Plans”).  As of December 31, 2017, we also maintained one defined benefit plan in the U.K. (the “U.K. Plan”), and we maintained two funded 
and two unfunded defined benefit plans in Norway (the “Norway Plans”).  Even though benefits under some of our defined benefit pension 
plans have ceased accruing, we maintain the respective pension obligations under such plans until they have been fully satisfied.  During 
the year ended December 31, 2017, we permitted certain participants of our U.K. Plan to make a one-time election to receive a payment of 
retirement benefits in the form of a lump sum distribution.  During the year ended December 31, 2016, we satisfied our obligations under 
four funded defined benefit plans in Norway and an unfunded defined benefit plan in Nigeria.  We refer to the U.K. Plan, the Norway Plans 
and  the  plan  in  Nigeria,  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. 

The following table presents the amounts and weighted-average assumptions associated with the U.S. Plans, the Non-U.S. Plans 

and the OPEB Plans (in millions, except percentages).

(a)  Amounts presented before tax. 
(b)  Weighted-average based on relative average projected benefit obligation for the year. 
(c)  Weighted-average based on relative average fair value of plan assets for the year. 

Net periodic benefit cost—Net periodic benefit costs increased for the year ended December 31, 2017 compared to the year 
ended December 31, 2016 primarily due to a decrease in expected returns from plan assets.  In the year ending December 31, 2018, we 
expect our net periodic benefit costs to represent income of approximately $12 million. 

Plan assets—In the year ended December 31, 2017, the fair value of the investments in the funded Transocean Plans increased 
by $132 million, or 8 percent, primarily due to the following: $229 million resulting from investment returns, and $36 million resulting from net 
gains on currency exchange rate changes for our non-U.S. Plans, partially offset by $133 million resulting from benefits paid from plan assets, 
net of contributions. 

Funding contributions—We review the funded status of our plans at least annually and contribute an amount at least equal to 
the minimum amount required.  For the funded qualified U.S. Plan, we contribute an amount at least equal to that required by the Employee 
Retirement Income Security Act of 1974 (“ERISA”) and the Pension Protection  Act of 2006 (“PPA”).  We use actuarial computations to 
establish  the  minimum  contribution  required  under  ERISA  and  PPA  and  the  maximum  deductible  contribution  allowed  for  income  tax 
purposes.    For  the  funded  U.K. Plan,  we  contribute  an  amount,  as  mutually  agreed  with  the  plan  trustees,  based  on  actuarial 
recommendations.  For the funded Norway Plans, we contribute an amount determined by the plan trustee based on Norwegian pension 
laws.  For the unfunded Transocean Plans and OPEB Plans, we generally fund benefit payments for plan participants as incurred.  We fund 
our contributions to the Transocean Plans and the OPEB Plans using cash flows from operations.  In the year ended December 31, 2017, 
we contributed $15 million and participants did not contribute to the Transocean Plans and the OPEB Plans.  In the year ended December 31, 
2016, we contributed $49 million and participants contributed $1 million to the Transocean Plans and the OPEB Plans.  For the year ending 
December 31, 2018, we expect to contribute $12 million to the Transocean Plans and $3 million to the OPEB Plans.

Off-Balance Sheet Arrangements 

We had no off-balance sheet arrangements as of December 31, 2017. 

Related Party Transactions 

As of December 31, 2017, we did not have any material related party transactions that were not in the ordinary course of business  

Other Matters 

Macondo well incident 

We believe the most notable remaining claims against us arising from the Macondo well incident are the 30 settlement class opt 
outs from the PSC Settlement Agreement.  We can provide no assurance as to the outcome of the remaining claims arising from the Macondo 
well incident or that we will not enter into additional settlements as to some or all of the remaining matters related to the Macondo well 
incident.  See Notes to Consolidated Financial Statements—Note 10—Commitments and Contingencies. 

Regulatory matters 

Consent Decree—Pursuant to a civil consent decree by and among the DOJ and certain of our affiliates (the “Consent Decree”), 
which was approved by the court on February 19, 2013, we agreed to undertake certain actions, including enhanced safety and compliance 
actions when operating in U.S. waters.  The Consent Decree also 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.  We may request termination of the 
Consent Decree after January 2, 2019, provided we meet certain conditions.  The Consent Decree resolved the claim by the U.S. for civil 
penalties under the Clean Water Act.  We also agreed to pay, and have satisfied our obligations to pay, civil penalties of $1.0 billion plus 
interest.  See Notes to Consolidated Financial Statements—Note 10—Commitments and Contingencies. 

Other regulatory matters— In addition, from time to time, we 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. 

Tax matters 

We conduct operations through our various subsidiaries in a number of 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.  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 statement of 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 6—
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.    On  an  ongoing  basis,  we  evaluate  our  estimates,  including  those  related to  our  allowance  for  doubtful  accounts, 
materials and supplies obsolescence, property and equipment, income taxes, contingent liabilities and defined benefit pension and other 
postemployment  benefit  plans.    These  estimates  require  significant  judgments  and  assumptions.    We  base  our  estimates  on  historical 
experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis 
for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources.  Actual results 
may differ from these estimates. 

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 upon the tax laws and rates in the countries in which we operate and earn income.  The relationship 

AR-45 

 
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.  Generally, our annual marginal tax rate is lower than our annual effective tax rate.  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, 
2017 and 2016, the liability for estimated tax exposures in our jurisdictions of operation was approximately $309 million and $370 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.  Due to the timing of the enactment of the 2017 Tax Act, it is not practicable to estimate the 
amount of indefinitely reinvested earnings or the deferred tax liability related to unremitted earnings of our subsidiaries. 

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 the foreign subsidiaries of our U.S. subsidiaries.  Prior to enactment of 
the 2017 Tax Act, we did not recognize a deferred tax liability related to the unremitted earnings of the foreign subsidiaries  of our U.S. 
subsidiaries because we considered those foreign earnings to be indefinitely reinvested.  Upon enactment of the 2017 Tax Act, we did not 
have the necessary information available, prepared and analyzed to develop a reasonable estimate of the transition tax.  We have not yet 
completed our calculation of the post-1986 earnings and profits for the foreign subsidiaries of our U.S. subsidiaries or determined the amounts 
of those earnings held in cash and other assets necessary to determine the transition tax.  The determination of the transition tax requires 
further analysis regarding the amount and composition of our historical foreign earnings, which is expected to be completed and reflected in 
our financial statements issued for subsequent reporting periods that fall within the measurement period provided by SAB 118.  The transition 
tax will also impact the utilization of our foreign tax credits and net operating losses generated in the U.S. which will impact our valuation 
allowance analysis related to those deferred tax assets and could have a material impact or our valuation allowances.  Because we have 
not completed our analysis of the amount and composition of our historical foreign earnings and the associated transition tax, we also cannot 
determine the associated impact on our assertion that the unremitted earnings of the foreign subsidiaries of our U.S. subsidiaries will be 
indefinitely reinvested. 

We continually evaluate strategies that could allow for the future utilization of our deferred tax assets.  During the year ended 
December 31, 2017, in evaluating our projected realizability of deferred tax assets, we considered our consolidated cumulative loss incurred 
over the recent three-year period, primarily due to losses on impairment and disposal of assets, together with potential organizational changes 
that could alter our ability to realize deferred tax assets, which have limited our ability to consider other subjective evidence, such as projected 

AR-46 

 
contract activity.  During the year ended December 31, 2016, in evaluating our projected realizability of deferred tax assets, we considered 
potential organizational changes that could alter our ability to realize deferred tax assets. 

See Notes to Consolidated Financial Statements—Note 6—Income Taxes. 

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, 2017 and 2016, the carrying 
amount of our property and equipment was $17.4 billion and $21.1 billion, respectively, representing 78 percent 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, 2017, 
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  $34 million  and  a  hypothetical  one-year  decrease  would  cause  an  increase  in  our  annual  depreciation  expense  of 
approximately $52 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, deepwater 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 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  weight  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  year  ended  December 31,  2015,  we  recognized  losses  of 
$507 million ($481 million, net of tax) and $668 million ($654 million, net of tax) associated with the impairment of the deepwater floater asset 
group and the midwater floater asset group, respectively. 

See Notes to Consolidated Financial Statements—Note 5—Drilling Fleet. 

AR-47 

 
Revenue recognition—Our contracts to provide offshore drilling services are individually negotiated and vary in their terms and 
provisions.    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 zero rates 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.  We recognize operating revenues as they are realized 
and earned and can be reasonably measured, based on contractual dayrates, and when collectability is reasonably assured.  For contractual 
daily rate contracts, we recognize the losses for loss contracts as such losses are incurred. 

Certain of our drilling contracts may be cancelable for the convenience of the customer upon payment of an early termination 
payment.  We recognize revenues, presented in other revenues, associated with cancellations or early terminations over the period in which 
we  satisfy  our  performance  obligations  based  on  the  negotiated  or  contractual  terms,  which  are  typically  specific  to  the  contractual 
arrangement.  In the years ended December 31, 2017 and 2016, we recognized revenues of $201 million and $471 million, respectively, 
associated with cancellations and early terminations. 

See Notes to Consolidated Financial Statements—Note 3—Accounting Standards Updates. 

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, 2017 and 2016, 
the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $219 million 
and $250 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 10—Commitments and Contingencies. 

Pension and other postemployment benefits—We use a January 1 measurement date for net periodic benefit costs and a 
December 31  measurement  date  for  projected  benefit  obligations  and  plan  assets.    We  measure  our  pension  liabilities  and  related  net 
periodic benefit costs using actuarial assumptions based on a market-related value of assets that reduces year-to-year volatility.  In applying 
this approach, we recognize investment gains or losses subject to amortization over a five-year period beginning with the year in which they 
occur.  Investment gains or losses for this purpose are measured as the difference between the expected and actual returns calculated using 
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.    Actual  results  may  differ  from  these 
measurements under different conditions or assumptions.  Future changes in plan asset returns, assumed discount rates and various other 
factors related to the pension plans will impact our future pension obligations and net periodic benefit costs. 

Additionally,  the  pension  obligations  and  related  net  periodic  benefit  costs  for  our  defined  benefit  pension  and  other 
postemployment benefit plans are actuarially determined and are affected by assumptions, including long-term rate of return, discount rates, 
mortality rates and employee turnover rates.  For our defined benefit plans that have ceased accruing benefits, certain assumptions, including 
compensation increases and health care cost trend rates no longer apply.  The two most critical assumptions are the long-term rate of return 
and the discount rate.  For the long-term rate of return of plan assets, we develop our assumptions based on historical experience and 
projected returns for the investments considering each plan’s target asset allocation and long-term asset class expected returns.  For the 
discount rate, we develop our assumptions utilizing a yield curve approach based on Aa-rated corporate bonds and the expected timing of 
future benefit payments.  We periodically evaluate our assumptions and, when  appropriate, adjust the recorded liabilities and expense.  
Changes in these and other assumptions used in the actuarial computations could impact our projected benefit obligations, pension liabilities, 
net  periodic  benefit  costs  and  other  comprehensive  income.    See  “—Pension  and  Other  Postemployment  Benefit  Plans”  and  Notes  to 
Consolidated Financial Statements—Note 9—Postemployment Benefit Plans.

Quantitative and Qualitative Disclosures About Market Risk 

Interest rate risk —We are exposed to interest rate risk, primarily associated with our long-term debt instruments.  The following 
table presents the principal cash flows and related weighted-average interest rates of our debt instruments by contractual maturity date.  The 
following table presents information for the years ending December 31 (in millions, except interest rate percentages):

_______________________________ 
(a)  Expected maturity amounts are based on the face value of debt. 

At December 31, 2017 and 2016, the fair value of our debt was $7.5 billion and $8.2 billion, respectively.  During the year ended 
December 31, 2017, the fair value of our debt decreased by $680 million due to the following: (a) a decrease of approximately $2.2 billion 
resulting from our repayment of $2.2 billion aggregate principal amount of debt (see Notes to Consolidated Financial Statements—Note 8—
Debt), partially offset by (b) an increase of approximately $1.1 billion resulting from the issuance of $410 million and $750 million aggregate 
principal amount of the 5.52% senior secured notes due May 2022 and the 7.50% senior unsecured notes due January 2026, respectively, 
and (c) an increase of approximately $400 million resulting from the change in market prices for our outstanding debt. 

The majority of our cash equivalents and short-term investments is subject to variable interest rates or short-term interest rates 
and such cash equivalents and short-term investments would earn commensurately higher rates of return if interest rates increase.  Based 
upon the amounts of our short-term investments as of December 31, 2017 and 2016, a hypothetical one percentage point change in interest 
rates would result in a corresponding change in annual interest income of approximately $25 million and $31 million, respectively. 

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 payment 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.    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.

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, 2017.  In making this assessment, management used the criteria set 
forth by the Committee of Sponsoring Organizations of the Treadway Commission, as described in Internal Control-Integrated Framework, 
as published in 2013.  Based on this assessment, management believes that the Company maintained effective internal control over financial 
reporting as of December 31, 2017. 

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 

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, 2017, 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, 2017, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 
consolidated balance sheets of the Company as of December 31, 2017 and 2016, 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, 2017, and the related 
notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 21, 2018, 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.

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, 
2017 and 2016, 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, 2017, and the related notes and financial statement schedule listed in the Index at Item 15(a) 
(collectively  referred  to  as  the  financial  statements).    In  our  opinion,  the  financial  statements  present  fairly,  in  all  material  respects,  the 
consolidated financial position of the Company at December 31, 2017 and 2016, and the consolidated results of its operations and its cash 
flows for each of the three years in the period ended December 31, 2017, 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, 2017, 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 21, 2018 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.

Zurich, February 21, 2018 

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  Group),  which 
comprise  the  consolidated  balance  sheets  as  of  December 31,  2017  and  2016,  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,  2017  (pages  AR-56  –  AR-90).    In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material 
respects, the consolidated financial position of the Group as of December 31, 2017 and 2016, and the consolidated results of its operations 
and its cash flows for each of the three years in the period ended December 31, 2017, 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 ac counting 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.  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 accompanying consolidated financial statements.

Revenue recognition, including contract modification  

Area of emphasis  Transocean Ltd. recognizes contract drilling revenue as realized and earned that can be reasonably measured, 
based on contractual daily rates and when collectability is reasonably assured.  Revenues for contract preparation, 
mobilization and capital improvements to the rig are deferred and recognized over the primary contract term.  There 
is  a  risk  of  improper  revenue  recognition  related  to  the  accounting  for  terms  and  conditions  of  the  contractual 
arrangement due to error or intent.  The risk may apply to new contracts as well as amendments or terminations 
resulting from demands, pressures, or disputes from customers.  The principal consideration for our determination 
that revenue recognition, including contract modification is a key audit matter is the subjective judgment involved in 
the  interpretation  of  contractual  terms  that  may  be  required  in  determining  that  all  criteria  have  been  met  to 
recognize revenue.  

See note 2 to these consolidated financial statements for Transocean Ltd.’s description of the accounting policy 
for revenue recognition.  

Our audit 
response 

Our audit procedures related to the key audit matter of revenue recognition, including contract modification included 
the following procedures:  

We tested the effectiveness of controls over Transocean Ltd.’s review of new and amended contracts including the 
assessment of the accounting for the arrangement.  We inspect a list of all contracts entered into during the year, 
including modifications, and evaluate terms summarized by management for those that would require subjective 
judgment.  We test contracts utilizing a risk based approach to verify management has appropriately considered 
the application of the terms. We tested the accounting treatment for contracts terminated during the current fiscal 
year including validation that the revenue recognition criteria had been met and Transocean Ltd.’s performance 
obligations had been satisfied.  We used analytical procedures to identify transactions with attributes suggesting 
changes of terms and conditions of the underlying arrangement not identified through our other procedures.  We 
performed inquiries with members of the operations management team, including the marketing department, to 
corroborate the contract documentation obtained. 

Long-lived assets impairment 

Area of emphasis  Transocean Ltd. reviews 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, recoverability is determined by evaluating the estimated 
undiscounted future net cash flows based on projected dayrates and utilization of the asset group under review. 
Transocean Ltd.  considers  asset  groups  to  be  ultra-deepwater  floaters,  harsh  environment  floaters,  deepwater 
floaters and midwater floaters.  When an impairment of one or more asset groups is indicated, the impairment is 
calculated as the amount by which the asset group’s carrying amount exceeds its estimated fair value.  

Transocean Ltd. measures the fair values of its contract drilling asset groups by applying a variety of valuation 
methods, incorporating a combination of income and market approaches, using projected discounted cash flows 
and estimates of the 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. 

The  primary  risks  are  incorrect  determination  of  asset  classes  and  subsequent  calculation  of  recoverability, 
inaccurate models being used for the impairment assessments, and that the assumptions to support the value of 
asset classes are inappropriate.  The principal consideration for our determination that impairment of long-lived 
asset  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  5  to  these  consolidated  financial  statements  for  Transocean  Ltd.’s  related  to  long-lived  assets 
impairments. 

Our audit 
response 

Our  audit  procedures  related  to  the  key  audit  matter  of  long-lived  assets  impairment  included  the  following 
procedures:  

We  tested  the  effectiveness  of  controls  over  Transocean Ltd.’s  long-lived  assets  impairment.    We  performed 
inquiries  of  management  about  the  current  market  conditions  supporting  the  evaluation  of  potential  impairment 
indicators, assessed Transocean Ltd.’s determination of asset groups, we 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 the impairment analyses, specifically in testing key 
assumptions and prospective financial information related to the midwater asset group.  

AR-54 

 
 
We also evaluated management’s annual reassessment of the remaining useful lives and salvage values of its 
long-lived assets given the current market condition. 

We performed procedures to assess the valuation models for evidence of management bias considering contrary 
evidence from third party analyst reports from and press releases. 

Realizability of deferred tax assets 

Area of emphasis   Transocean Ltd. measures 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.  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.  
Estimates,  judgments  and  assumptions  are  required  in  determining  whether  deferred  tax  assets  will  be  fully  or 
partially realized. 

As  a  result  of  the  significant  impairment  charges  in  2017  recognized  on  assets  held  for  sale  and  disposals, 
Transocean Ltd.  is  in  a  consolidated  three-year  cumulative  loss  position.    The  principal  consideration  for  our 
determination that the realizability of deferred tax assets is a key audit matter is the judgment involved in determining 
the  sources  of  income  available  to  realize  the  deferred  tax  assets,  including  tax  planning  strategies,  available 
carrybacks, and utilization of deferred tax liabilities and uncertain tax positions.  The three-year cumulative loss 
position also limits the ability to consider other subjective evidence, such as projected contract activity. 

See note 6 to these consolidated financial statements for Transocean Ltd.’s disclosures related to income taxes. 

Our audit 
response 

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

We tested the effectiveness of controls over Transocean Ltd.’s process to assess the realizability of deferred tax 
assets.  We involved EY tax professionals regarding Transocean’s assessment and conclusion that it is more likely 
than not to realize its deferred tax assets based on the identified sources of future taxable income. 

We performed procedures to evaluate management’s assessment, including testing forecasted income, evaluating 
prudent  and  feasible  tax  planning  strategies,  agreeing  carrybacks  available  to  prior  year  tax  returns,  tracing 
uncertain tax positions to account details, and recalculating the valuation allowances required.  

Report on other legal requirements 

We are a public accounting firm registered with the Swiss Federal Audit Oversight Authority (FAOA) and the PCAOB and we confirm that we 
meet the legal requirements on licensing according to the Auditor Oversight Act (AOA). We are independent with respect to the Group in 
accordance with Swiss law (article 728 CO and article 11 AOA) and U.S. federal securities laws as well as the applicable rules and regulations 
of  the  Swiss  audit  profession,  the  U.S.  Securities  and  Exchange  Commission  and  the  PCAOB,  and  we  have  fulfilled  our  other  ethical 
responsibilities in accordance with these requirements. 

In accordance with article 728a para. 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 consolidated financial statements according to the instructions of the Board of Directors.  

We recommend that the consolidated financial statements submitted to you be approved. 

We have served as the Company’s auditor since 2008.

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.  At December 31, 2017, we owned or had partial 
ownership interests in and operated 39 mobile offshore drilling units, including 26 ultra-deepwater floaters, seven harsh environment floaters, 
two deepwater floaters and four midwater floaters.  At December 31, 2017, we also had three ultra-deepwater drillships under construction 
or under contract to be constructed.  See Note 5—Drilling Fleet. 

Business  combination—On  August 13,  2017,  we  entered 

the 
“Transaction Agreement”) with Songa Offshore SE, a European public company limited by shares, or societas Europaea, existing under the 
laws of Cyprus (“Songa”), pursuant to which we agreed to offer to acquire all of the issued and outstanding shares of Songa, subject to 
certain conditions, through a public voluntary exchange offer (the “Offer”).  At December 31, 2017, Songa owned and operated seven mobile 
offshore drilling units, including five harsh environment floaters and two midwater floaters.  See Note 20—Subsequent Event. 

transaction  agreement 

(as  amended, 

into  a 

Disposition—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.    At  December 31,  2017  we  continued  to  operate 
two high-specification jackups that were under contract when we sold the rigs, and we will continue to operate such rigs until completion or 
novation of the respective drilling contracts.  See Note 5—Drilling Fleet. 

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, income taxes, contingencies, share-based compensation, defined benefit pension and other 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 multiple input levels are required for a valuation, 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 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  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 4—Variable Interest 
Entities and Note 11—Noncontrolling Interest. 

Business  combination—In  connection  with  our  acquisition  of  Songa,  we  will  apply  the  acquisition  method  of  accounting.  
Accordingly, we will record the acquired assets and assumed liabilities at fair value and recognize goodwill to the extent the fair value of the 
business acquired exceeds the fair value of the net assets.  We will estimate the fair values of the acquired assets and assumed liabilities 
as of the date of the acquisition, and our estimates will 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.  See Note 20—Subsequent Event. 

AR-61 

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

Operating revenues and expenses—We recognize operating revenues as they are realized and earned and can be reasonably 
measured, based on contractual dayrates, and when collectability is reasonably assured.  In certain instances, when we determine that 
collection is not reasonably assured, we recognize revenues associated with the contract when all revenue recognition criteria have been 
met.  In connection with drilling contracts, we may receive revenues for preparation and mobilization of equipment and personnel or for 
capital improvements to rigs.  We defer the revenues earned and incremental costs incurred that are directly related to contract preparation 
and mobilization and recognize such revenues and costs over the primary contract term of the drilling project using the straight-line method.  
We recognize, in operating and maintenance costs and expenses, the fees related to contract preparation and mobilization on a straight-line 
basis over the estimated firm period of drilling, which is consistent with the general pace of activity, level of services being provided and 
dayrates being earned over the life of the contract.  For contractual daily rate contracts, we recognize the losses for loss contracts as such 
losses are incurred.  We recognize the costs of relocating drilling units without contracts to more promising market sectors as such costs are 
incurred.  Upon completion of drilling contracts, we recognize in earnings any demobilization fees received and expenses incurred.  We defer 
capital upgrade revenues received and recognize such revenues over the primary contract term of the drilling project.  We depreciate the 
actual costs incurred for the capital upgrade on a straight-line basis over the estimated useful life of the asset.  We defer the periodic survey 
and drydock costs incurred in connection with obtaining regulatory certification to operate our rigs and well control systems on an ongoing 
basis, and we recognize such costs over the period until the next survey using the straight-line method.  See Note 3—Accounting Standards 
Updates. 

Our other revenues represent those derived from customer contract terminations and customer reimbursable items.  We recognize 
revenues from contract terminations as we fulfill our obligations for such terminations and when all contingencies have expired.  We recognize 
customer reimbursable revenues as we bill our customers for reimbursement of costs associated with certain equipment, materials and 
supplies, subcontracted services, employee bonuses and other expenditures, resulting in little or no net effect on operating income since 
such recognition is concurrent with the recognition of the respective reimbursable costs in operating and maintenance expense. 

Share-based compensation—To measure the fair values of stock options and stock appreciation rights 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 restricted share units that are subject to performance targets, 
we use the market price of our shares on the measurement date for the projected number of shares expected to be earned at the end of the 
performance period.  To measure the fair values of granted or modified restricted share units that are 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  apply 
assumptions using 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.  For service awards, we recognize 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.  For 
performance awards with graded vesting conditions, we recognize compensation expense on a straight-line basis over the service period for 
each separately vesting portion of the award as if the award was, in substance, multiple awards.  In the years ended December 31, 2017, 
2016 and 2015, share-based compensation expense was $41 million, $42 million and $64 million, respectively.  See Note 13—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.  As of December 31, 2017, we had ceased 
capitalization  of  interest  costs  on  one uncontracted  newbuild  drillship  due  to  a  pause  in  construction  in  progress.    In  the  years  ended 
December 31,  2017,  2016  and  2015,  we  capitalized  interest  costs  of  $116 million,  $176 million  and  $140 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, 2017, 2016 and 2015, we recognized a net loss of 
$6 million, a net loss of $2 million and a net gain of less than $1 million, respectively, related to currency exchange rates. 

Income taxes—We provide for income taxes based upon the tax laws and rates in effect in the countries in which operations are 
conducted and income is earned.  We recognize the effect of changes in tax laws as of the date of enactment.  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.  

AR-62 

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

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 6—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  and  companies  with  high  credit  ratings.    At 
December 31, 2017, the carrying amount of our short-term investments was $450 million. 

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, 2017 and 2016, 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, 2017 and 2016, the allowance for obsolescence was $141 million and $153 million, respectively. 

Restricted cash accounts and investments—We maintain restricted cash balances 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  investment  balances  in  current  assets  if  the 
restriction is expected to expire or otherwise be resolved within one year and in other assets if the restriction is expected to expire or otherwise 
be  resolved  in  greater  than  one year.    At  December 31,  2017,  the  aggregate  carrying  amount  of  our  restricted  cash  investments  was 
$489 million, of which $466 million and $23 million was classified in current assets and other assets, respectively.  At December 31, 2016, 
the aggregate carrying amount of our restricted cash investments was $510 million, of which $466 million and $44 million was classified in 
current assets and other assets, respectively.  See Note 3—Accounting Standards Updates, Note 8—Debt and Note 10—Commitments and 
Contingencies. 

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, 2017 and 2016, the aggregate carrying amount of our assets held for sale, recorded in other 
current assets, was $22 million and $6 million, respectively.  See Note 5—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, 2017, the aggregate carrying amount of our property and equipment represented approximately 
78 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 25 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, 

AR-63 

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

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, deepwater 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. 

In the year ended December 31, 2017, we determined that the carrying amount of the midwater floater asset group exceeded its 
fair value, and we recognized a loss of $94 million ($93 million, or $0.25 per diluted share, net of tax) associated with the impairment of these 
long-lived assets.  In the year ended December 31, 2016, we determined that the carrying amount of the deepwater floater asset group 
exceeded its fair value, and we recognized a loss of $52 million  ($0.14 per diluted share), which had no tax effect, associated  with the 
impairment of these long-lived assets.  In the year ended December 31, 2015, we determined that the carrying amount of the deepwater 
floater asset group and the midwater floater asset group each exceeded its fair value, and we recognized a loss of $507 million ($481 million, 
or $1.31 per diluted share, net of tax) and $668 million ($654 million, or $1.78 per diluted share, net of tax) associated with the impairment 
of  the  deepwater  floater  asset  group  and  the  midwater  floater  asset  group,  respectively,  including  a  loss  of  $52 million  associated  with 
construction in progress related to the asset groups.  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.  See Note 5—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.  Investment gains or losses for this purpose are measured 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, including long-term rate of return on plan assets, discount 
rates, mortality rates and employee turnover rates.  For our defined benefit plans that have ceased accruing benefits, certain assumptions, 
including compensation increases and health care cost trend rates no longer apply.  The two most critical assumptions are the long-term 
rate of return on plan assets and the discount rate. 

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.    For  the  projected  compensation  trend  rate,  we  consider  short-term  and  long-term  compensation  expectations  for 
participants, including salary increases and performance bonus payments. 

At December 31, 2017 and 2016, our pension and other postemployment benefit plan obligations represented an aggregate liability 
of $359 million and $375 million, respectively, and an aggregate asset of $17 million and $5 million, respectively, representing the funded 
status of the plans.  In the years ended December 31, 2017, 2016 and 2015, aggregate net periodic benefit costs were costs of $5 million, 
income of $11 million and costs of $26 million, respectively.  See Note 3—Accounting Standards Updates and Note 9—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 

AR-64 

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

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.  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 

Stock compensation—Effective January 1, 2017, we adopted the accounting standards update that allows for simplification of 
the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or 
liabilities and classification on the statement of cash flows.  The update is effective for annual periods beginning after December 15, 2016 
and interim periods within those annual 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. 

Recently issued accounting standards 

Revenue  from  contracts  with  customers—Effective  January 1,  2018,  we  will  adopt  the  accounting  standards  update  that 
requires an entity to recognize revenue to depict 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.  The update is effective for annual reporting 
periods beginning after December 15, 2017, including interim periods within that reporting period.  Given the interaction with the accounting 
standards update related to leases, we expect to adopt the updates concurrently, effective January 1, 2018.  We expect to apply the modified 
retrospective approach to our adoption, which is consistent, in application, with the approach we expect to elect under the lease accounting 
standards update.  We have determined we have one revenue stream.  Our adoption, and the ultimate effect on our consolidated financial 
statements, will be based on an evaluation of the contract-specific facts and circumstances.  Although we do not expect any changes to the 
timing of our revenue recognition for our current drilling contracts with customers, we are still evaluating the disclosures that will be contained 
in our note to consolidated financial statements.  We are continuing to evaluate the requirements and the other effects such requirements 
may have on our consolidated statements of financial position, operations and cash flows and on the disclosures contained in our notes to 
consolidated financial statements. 

Leases—Effective  January 1,  2018,  we  intend  to  early  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.  The update, which 
permits early adoption, is effective for interim and annual periods beginning after December 15, 2018, including interim periods within those 
annual periods.  Under the updated definition of a lease, we have determined that our drilling contracts contain a lease component.  We 
intend to early adopt these accounting standards, effective January 1, 2018, given the interaction with the accounting standards update 
related to revenue from contracts with customers.  In a recent update, targeted improvements were proposed to the accounting standards 
that provides 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.  If the targeted improvements are approved, we intend to apply the alternative 
transition method, which is consistent, in application, with the approach we expect to elect under the revenue accounting standards update, 
and intend to elect the practical expedient for lessors for presentation purposes.  Our adoption, and the ultimate effect on our consolidated 
financial statements, will be based on an evaluation of the contract-specific facts and circumstances.  We do not expect any changes to the 
timing of our revenue recognition for our current drilling contracts with customers.  Additionally, based on the lease arrangements under 
which we are the lessee as of December 31, 2017, we expect to recognize an aggregate lease liability and a corresponding right-to-use 
asset of between $65 million and $75 million.  We are continuing to evaluate the requirements with regard to arrangements under which we 
are the lessor and the other effects such requirements may have on our consolidated statements of financial position, operations and cash 
flows and on the disclosures contained in our notes to consolidated financial statements. 

Statement  of  cash  flows—Effective  January 1,  2018,  we  will  adopt  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.  The update, which permits early adoption, is effective 
for annual periods beginning after December 15, 2017 and interim periods within those annual periods.  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 will remove the effect of proceeds from and deposits to restricted accounts from our cash flows provided by or used in operating 
and financing activities, as applicable.  For the years ended December 31, 2017, 2016 and 2015, such changes would have resulted in an 
increase of $26 million, $69 million and $242 million, respectively, to cash flows provided by operating activities and for the years ended 
December  31,  2017  and  2016,  an  increase  of  $97 million,  and  $61 million,  respectively,  to  cash  flows  provided  by  or  used  in  financing 
activities.

Income taxes—Effective January 1, 2018, we will adopt 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.  The update, which permits early adoption, is effective for annual reporting periods beginning after 
December 15, 2017, including interim periods within those annual periods.  We do not expect that our adoption will 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 will adopt 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.  The update, which 
permits early adoption, is effective for annual periods beginning after December 15, 2017, including interim periods within those annual 
periods.  We do not expect that our adoption will have a material effect on our consolidated statements of cash flows or on the disclosures 
contained in our notes to consolidated financial statements. 

Note 4—Variable Interest Entity 

Angola Deepwater Drilling Company Limited (“ADDCL”), a consolidated Cayman Islands company, is a joint venture company 
formed to own and operate certain drilling units.  We determined that ADDCL met the criteria of a variable interest entity for accounting 
purposes because its equity at risk was insufficient to permit it to carry on its activities without additional subordinated financial support from 
us.  We also determined, in each case, that we were the primary beneficiary for accounting purposes since (a) we had the power to direct 
the  construction,  marketing  and  operating  activities,  which  are  the  activities  that  most  significantly  impact  each  entity’s  economic 
performance, and (b) we had the obligation to absorb losses or the right to receive a majority of the benefits that could be potentially significant 
to  the  variable  interest  entity.    As  a  result,  we  consolidate  ADDCL  in  our  consolidated  financial  statements,  we  eliminate  intercompany 
transactions, and we present the interests that are not owned by us as noncontrolling interest on our consolidated balance sheets.  The 
carrying amounts associated with ADDCL, after eliminating the effect of intercompany transactions, was as follows (in millions):

Impairments of assets held and used—During the years ended December 31, 2017, 2016 and 2015, we identified indicators 

that the asset groups in our contract drilling services reporting unit may not be recoverable. 

In the year ended December 31, 2017, such indicators included a significant decline in commodity prices and the market value of 
our stock, a reduction of projected dayrates and a further 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, such indicators included a reduction of projected dayrates and an extension to low utilization 
rates.  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. 

In the year ended December 31, 2015, such indicators included a reduction in the number of new contract opportunities, customer 
suspensions of drilling programs, early contract terminations and cancellations and low dayrate fixtures.  In the year ended December 31, 
2015, as a result of our testing, we recognized losses of $507 million ($481 million, or $1.31 per diluted share, net of tax) and $668 million 
($654 million, or $1.78 per diluted share, net of tax) associated with the impairment of the deepwater floater asset group and the midwater 
floater asset group, respectively, including losses of $41 million and $11 million, respectively, associated with construction in progress for 
each asset group. 

We estimated 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 estimates 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, 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. 

In the year ended December 31, 2015, we recognized an aggregate loss of $700 million ($585 million, or $1.60 per diluted share, 
net of tax) associated with the impairment of the ultra-deepwater floaters Deepwater Expedition and GSF Explorer, the deepwater floaters 
Deepwater Navigator,  Discoverer Seven Seas,  GSF Celtic Sea,  Sedco 707  and  Transocean Rather  and 
floaters 
GSF Aleutian Key,  GSF Arctic III,  GSF Grand Banks,  GSF Rig 135,  Transocean Amirante  and  Transocean Legend,  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 based on comparable units to be 
sold for scrap value or alternative purposes.  If we commit to plans to sell additional rigs for values below the respective carrying amounts, 
we may be required to recognize additional losses in future periods associated with the impairment of such assets.

novated  the  contracts  relating  to  the  construction  of  five high-specification  jackups,  together  with  related  assets.    In  the  year ended 
December 31, 2017, we received aggregate net cash proceeds of $319 million and recognized an aggregate net loss of $1.6 billion ($4.08 per 
diluted share), which had no tax effect, associated with the disposal of these assets.  Following the completion of the sale, we agreed to 
continue to operate three of these high-specification jackups through completion or novation of the respective drilling contracts, one of which 
was completed as of September 30, 2017.  In the year ended December 31, 2017, excluding our loss on the disposal of these assets, our 
operating results included income of $65 million, before taxes, associated with the high-specification jackup asset group.  In the years ended 
December 31, 2016 and 2015, our operating results included income of $74 million and $208 million, respectively, before taxes, associated 
with the high-specification jackup asset group. 

During the year ended December 31, 2017, we also completed the sale of the ultra-deepwater floater GSF Jack Ryan and the 
midwater floaters GSF Rig 140, Transocean Prospect and Transocean Searcher, along with related assets.  In the year ended December 31, 
2017,  we  received  aggregate  net  cash  proceeds  of  $22 million  and  recognized  an  aggregate  net  gain  of  $9 million  associated  with  the

Note 6—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 provision (benefit) for income taxes were as follows (in 
millions):

In the years ended December 31, 2017, 2016 and 2015, our effective tax rate was (3.1) percent, 11.5 percent and 11.9 percent, 

respectively, based on income from continuing operations before income tax expense.

At  December 31,  2017  and  2016,  our  deferred  tax  assets  included  U.S.  foreign  tax  credit  carryforwards  of  $37 million  and 
$33 million,  respectively,  which  will  expire  between  2018  and  2027.    The  deferred  tax  assets  related  to  our  net  operating  losses  were 
generated in various worldwide tax jurisdictions.  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.  
At December 31, 2016, the net operating losses carryforwards, which were generated in various jurisdictions worldwide, included $200 million 
that  do  not  expire  and  $183  million  that  will  expire  beginning  2018  and  2036.    At  December 31,  2017  and  2016,  due  to  uncertainty  of 
realization, we have recorded a valuation allowance of $574 million and $412 million, respectively, on net operating losses and other deferred 
tax assets. 

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 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. 

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, and 
accordingly, we have not provided for taxes on these unremitted earnings.  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 statement of 
financial position, results of operations or cash flows.  Due to the timing of the enactment of the 2017 Tax Act, as discussed below, it is not 
practicable to estimate the amount of indefinitely reinvested earnings or the deferred tax liability related to the indefinitely reinvested earnings 
due to the complexities associated with the underlying hypothetical calculations. 

Unrecognized tax benefits—The changes to our liabilities related to unrecognized tax benefits, excluding interest and penalties 

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

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

In  the  years  ended  December 31,  2017,  2016  and  2015,  we  recognized  income  of  $9 million,  $23 million  and  $1 million, 
respectively, recorded as a component of income tax expense, related to previously recognized interest and penalties associated with our 
unrecognized tax benefits.  As of December 31, 2017, if recognized, $309 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,  2018,  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 Tax Cuts and Jobs Act (the “2017 Tax Act”), which includes a number 
of changes to existing U.S. tax laws that have an impact on our income tax provision, most notably a reduction of the U.S. corporate income 
tax rate from 35 percent to 21 percent for tax years beginning after December 31, 2017, and the creation of a territorial tax system with a 
one-time mandatory tax on previously deferred foreign earnings of U.S. subsidiaries.  The 2017 Tax Act also makes prospective changes 
beginning  in  2018,  including  a  base  erosion  and  anti-abuse  tax  (“BEAT”),  a  global  intangible  low-taxed  income  (“GILTI”)  tax,  additional 
limitations on the deductibility of executive compensation, limitations on the deductibility of interest and repeal of the domestic manufacturing 
deduction.  We are still evaluating the GILTI tax, which imposes a tax on non-U.S. income in excess of a deemed return on tangible assets 
of non-U.S. corporations, and its prospective effect on future periods. 

We recognized the income tax effects of the 2017 Tax Act in our financial statements for the year ended December 31, 2017 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.  As such, our financial results reflect (a) the 
income tax effects of the 2017 Tax Act for which the accounting is complete, (b) provisional amounts for those specific income tax effects of 
the 2017 Tax Act for which the accounting is incomplete but a reasonable estimate could be determined and (c) no adjustments to current 
or deferred taxes for income tax effects for which the accounting is incomplete and a reasonable estimate could not be determined.  The 
2017 Tax Act’s U.S. tax law changes that we believe will have a material impact on our federal income taxes are as follows: 

Reduction of the U.S. corporate income tax rate—At December 31, 2017, we remeasured our deferred tax assets and liabilities to 
reflect the reduction in the U.S. corporate income tax rate from 35 percent to 21 percent, resulting in a $66 million increase in income tax 
expense for the year ended December 31, 2017 and a corresponding $66 million decrease in net deferred tax assets as of December 31, 
2017.  However, we are still analyzing certain aspects of the 2017 Tax Act and refining our calculations, which could potentially affect the 
measurement of these balances or potentially give rise to new deferred tax amounts. 

Transition tax on foreign earnings—The 2017 Tax Act imposes a one-time transition tax on certain unremitted earnings and profits 
of the foreign subsidiaries of our U.S. subsidiaries.  Prior to enactment of the 2017 Tax Act, we did not recognize a deferred tax liability 
related to the unremitted earnings of the foreign subsidiaries of our U.S. subsidiaries because we considered those foreign earnings to be 
indefinitely reinvested.  Upon enactment of the 2017 Tax Act, we did not have the necessary information available, prepared and analyzed 
to develop a reasonable estimate of the transition tax.  We have not yet completed our calculation of the post-1986 earnings and profits for 
the foreign subsidiaries of our U.S. subsidiaries or determined the amounts of those earnings held in cash and other assets necessary to 
determine the transition tax.  The determination of the transition tax requires further analysis regarding the amount and composition of our 
historical foreign earnings, which is expected to be completed and reflected in our financial statements issued for subsequent  reporting 
periods that fall within the measurement period provided by SAB 118.  The transition tax will also impact the utilization of our foreign tax 
credits and net operating losses generated in the U.S. which will impact our valuation allowance analysis related to those deferred tax assets 
and could have a material impact to our valuation allowances.  Because we have not completed our analysis of the amount and composition 
of our historical foreign earnings and the associated transition tax, we also cannot determine the associated impact on our assertion that the 
unremitted earnings of the foreign subsidiaries of our U.S. subsidiaries will be indefinitely reinvested. 

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 2010.  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

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

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 issued a tax assessment with respect to our tax returns 
for the years 2000 through 2004, which is currently for an aggregate amount of BRL 853 million, equivalent to approximately $258 million, 
including penalties and interest.  On January 25, 2008, we filed a protest letter with the Brazilian tax authorities for this tax assessment, and 
we are currently engaged in the appeals process.  On May 19, 2014, the Brazilian tax authorities issued an aggregate tax assessment with 
respect to our Brazilian income tax returns for the years 2009 and 2010, which is currently for an aggregate amount of BRL 145 million, 
equivalent to approximately $44 million, including penalties and interest.  On June 18, 2014, we filed a protest letter with the Brazilian tax 
authorities  for  this  tax  assessment.    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 a number of countries throughout the world.  Each 
country has its own tax regimes with varying nominal rates, deductions, employee contribution requirements 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.

(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 and borrowings under an unsecured five-year revolving credit facility (see “Five-Year 
Revolving  Credit  Facility”).    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.” 

(d)  Each subsidiary issuer of the respective unregistered senior secured notes is a wholly owned indirect subsidiary of Transocean Inc.  The senior secured 
notes are fully and unconditionally, jointly and severally, guaranteed by Transocean Ltd., Transocean Inc. and, in each case, the owner of the respective 
collateral rig.  See “—Debt issuances—Senior secured notes.”

Indentures—The indentures that govern our debt 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 
5.52% 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”  and, 
collectively with the 5.52% Senior Secured Notes and the 7.75% Senior Secured Notes, the “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 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 each rig’s earnings relative to the debt balance, that changes over the terms of the notes.  At  December 31, 2017, the 
Maximum  Collateral  Ratio  under  both  indentures  was  less  than  5.75 to  1.00.    See  Note 10—Commitments  and  Contingencies—Global 
Marine litigation. 

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, 2017, based on our Debt 
Rating on that date, the interest rate in effect for the 2.50% senior notes due October 2017 (the “2.50% Senior Notes”) and the 3.80% senior 
notes due October 2022 was 4.50 percent and 5.80 percent, respectively, and the interest rate in effect for the 6.375% senior notes due 
December 2021 and the 7.35% senior notes due December 2041 was 8.375 percent and 9.35 percent, respectively. 

Five-Year Revolving Credit Facility—In June 2014, we entered into an amended and restated bank credit agreement, which 
established  a  $3.0 billion  unsecured  five-year  revolving  credit  facility,  which  is  scheduled  to  expire  on  June 28,  2019  (the  “Five-Year 
Revolving  Credit  Facility”).    Among  other  things,  the  Five-Year  Revolving  Credit  Facility  includes  limitations  on  creating  liens,  incurring 
subsidiary debt, transactions with affiliates, sale/leaseback transactions, mergers and the sale of substantially all assets.  The Five-Year 
Revolving Credit Facility also includes a covenant imposing a maximum consolidated indebtedness to total tangible capitalization ratio of 
0.6 to 1.0.  Borrowings under the Five-Year Revolving Credit Facility are subject to acceleration upon the occurrence of an event of default.  
Additionally, such borrowings are guaranteed by Transocean Ltd. and may be prepaid in whole or in part without premium or penalty. 

We may borrow under the Five-Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate (“LIBOR”) 
plus a margin (the “Five-Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the Debt Rating, 
or (2) the base rate specified in  the credit agreement plus the Five-Year Revolving Credit Facility Margin, less one percent per annum.  
Throughout the term of the Five-Year Revolving Credit Facility, we pay a facility fee on the daily unused amount of the underlying commitment 
which ranges from 0.15 percent to 0.35 percent based on our Debt Rating.  At December 31, 2017, based on our Debt Rating on that date, 
the  Five-Year  Revolving  Credit  Facility  Margin  was  2.0 percent  and  the  facility  fee  was  0.35 percent.    At  December 31,  2017,  we  had 
no borrowings outstanding, $7 million of letters of credit issued, and we had $3.0 billion of available borrowing capacity under the Five-Year 
Revolving Credit Facility.  See Note 10—Commitments and Contingencies—Global Marine litigation. 

Debt issuances 

Priority guaranteed senior unsecured notes—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 are required to pay interest on the 7.50% Senior Notes semiannually on January 15 and 
July 15 of each year, beginning on July 15, 2018.  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 July 21, 2016, we completed an offering of an aggregate principal amount of $1.25 billion of 9.00% senior unsecured notes 
due July 15, 2023 (the “9.00% Senior Notes”), and we received aggregate cash proceeds of $1.21 billion, net of initial discount and costs

amount plus a make-whole provision, and on or after July 15, 2020, at specified redemption prices. 

Senior  secured  notes—On  May 5,  2017,  we  completed  an  offering  of  an  aggregate  principal  amount  of  $410 million  of 
5.52% Senior Secured Notes, and we received aggregate cash proceeds of $403 million, net of issue costs.  We are required to pay quarterly 
installments of principal and interest on the last business day of March, June, September and December of each year.  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 related to the drilling contract for Deepwater Conqueror, a make-whole amount.  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. 

On October 19, 2016, we completed an offering of an aggregate principal amount of $600 million 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.    We  are  required  to  pay  semiannual  installments  of  principal  and  interest  on  the 
7.75% Senior Secured Notes on April 15 and October 15 of each year, and we are required to pay semiannual installments of principal and 
interest on the 6.25% Senior Secured Notes on June 1 and December 1 of each year.  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.  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  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.  The 
7.75% Senior Secured Notes are secured by the assets and earnings associated with the ultra-deepwater floater Deepwater Thalassa and 
the equity of the wholly owned subsidiary that owns the collateral rig.  The 6.25% Senior Secured Notes are secured by the assets and 
earnings associated with the ultra-deepwater floater Deepwater Proteus and the equity of the subsidiary that owns the collateral rig.  At 
December 31, 2017 and 2016, we had $211 million and $103 million, respectively, deposited in restricted cash accounts to satisfy debt 
service  and  working  capital  requirements  for  the  Senior  Secured  Notes.    At  December 31,  2017,  the  aggregate  carrying  amount  of 
Deepwater Conqueror,  Deepwater Thalassa  and  Deepwater Proteus  was  $2.4 billion.    At  December 31,  2016,  the  aggregate  carrying 
amount of Deepwater Thalassa and Deepwater Proteus was $1.7 billion.

Note 9—Postemployment Benefit Plans 

Defined benefit pension and other postemployment benefit plans 

Overview—As of December 31, 2017, 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, 2017, the defined benefit plans in the U.S. included three funded and three 
unfunded  plans  (the  “U.S.  Plans”).    During  the  year  ended  December 31,  2016,  we  permitted  certain  participants  of  one of  our  funded 
U.S. Plans to make a one-time election to receive a payment of retirement benefits in the form of either (a) a lump sum distribution or (b) an 
annuity starting October 1, 2016. 

As of December 31, 2017, the defined benefit plan in the U.K. included one funded plan (the “U.K. Plan”).  During the year ended 
December 31, 2017, we permitted certain participants to make a one-time election to receive payment of retirement benefits in the form of a 
lump sum distribution.  As of December 31, 2017, the defined benefit plans in Norway, primarily group pension schemes with life insurance 
companies, included two funded and two unfunded plans, (the “Norway Plans”).  During the year ended December 31, 2016, we satisfied 
our obligations under four funded defined benefit plans in Norway and an unfunded defined benefit plan in Nigeria.  During the year ended 
December 31, 2015, we satisfied our obligations under unfunded defined benefit plans in Egypt and Indonesia.  We refer to the U.K. Plan, 
the Norway Plans and the plans in Nigeria, Egypt and Indonesia, 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.

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,  2017,  2016  and  2015,  we  made  an  aggregate  contribution  of 
$15 million, $49 million and $39 million, respectively, to the Transocean Plans and the OPEB Plans using our cash flows from operations.  
In the year ending December 31, 2018, we expect to contribute $12 million to the Transocean Plans, and we expect to fund benefit payments 
of approximately $3 million for the OPEB Plans as costs are incurred.

At  December 31,  2017,  we  sponsored  four  defined  contribution  plans,  including  (1) a  qualified  savings  plan  covering  certain 
employees working in the U.S. (the “U.S. Savings Plan”), (2) a non-qualified supplemental plan covering certain eligible employees working 
in the U.S. (the “U.S. Savings Restoration Plan”), (3) a qualified savings plan covering certain eligible U.K. employees (the “U.K. Savings 
Plan”) and (4) a non-qualified savings plan covering certain employees working outside the U.S. and U.K. (the “Non-U.S. Savings Plan”).  In 
the years ended December 31, 2017, 2016 and 2015, we recognized expense of $43 million, $51 million and $89 million, respectively, related 
to our defined contribution plans. 

The U.S. Savings Plan provides eligible employees with matching contributions up to 10.0 percent of each participant’s base salary 
and annual bonus based on the participant’s contribution to the plan.  The U.S. Savings Restoration Plan provides eligible employees with 
benefits in excess of those allowed under the U.S. Savings Plan. 

The U.K. Savings Plan provides eligible employees with matching contributions between 4.5 percent and 9.5 percent based on the 
participant’s contribution to the plan.  Effective January 1, 2017, the Non-U.S. Savings Plan, provides eligible employees with matching 
contributions up to 12 percent of each participant’s base salary based on the participant’s contribution to the plan.  In the years ended 
December 31, 2016 and 2015, the Non-U.S. Savings Plan provided eligible employees with matching contributions up to 6.0 percent and 
contributions between 4.5 percent and 6.5 percent of each participant’s base salary and annual bonus based on the participant’s years of 
eligible service. 

Note 10—Commitments and Contingencies 

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, 2017, 2016 and 2015, our rental expense for all operating leases, including operating leases with terms of 
less than one year, was approximately $52 million, $45 million and $72 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, 2017, 2016 and 2015, depreciation expense 
associated with  Petrobras 10000, the asset held under capital lease, was $23 million.  At December 31, 2017 and 2016, the aggregate 
carrying amount of this asset held under capital lease was as follows (in millions):

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, 2017, the aggregate future payments required under our purchase 
obligations and our service agreement obligations were as follows (in millions):

Letters of credit and surety bonds 

At December 31, 2017 and 2016, we had outstanding letters of credit totaling $29 million and $50 million, respectively, issued 
under various 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, 2017, the aggregate cash collateral held by banks for letters of 
credit was $7 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, 2017 and 2016, we had 
outstanding surety bonds totaling $51 million and $33 million, respectively 

Macondo well incident commitments and contingencies 

Overview—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. 

In the year ended December 31, 2015, we recognized income of $788 million ($735 million, or $2.02 per diluted share, net of tax) 
recorded  as  a  net  reduction  to  operating  and  maintenance  costs  and  expenses,  including  $538 million  associated  with  recoveries  from

insurance for our previously incurred losses, $125 million associated with partial reimbursement from BP for our previously incurred legal 
costs, and $125 million associated with a net reduction to certain related contingent liabilities, primarily associated with contingencies that 
have either been settled or otherwise resolved as a result of settlements with BP and the PSC. 

We  have  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, 2017 and 2016, 
the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $219 million 
and $250 million, respectively, recorded in other current liabilities, the majority of which is related to our settlement with the PSC. 

Plea Agreement—Pursuant to the plea agreement (the “Plea Agreement”), one of our subsidiaries pled guilty to one misdemeanor 
count of negligently discharging oil into the U.S. Gulf of Mexico, in violation of the Clean Water Act (“CWA”) and agreed to be subject to 
probation through February 2018.  We also agreed to make an aggregate cash payment of $400 million, including a criminal fine and cash 
contributions  to  the  National  Fish  &  Wildlife  Foundation  and  the  National  Academy  of  Sciences,  payable  in  scheduled  installments.    At 
December 31, 2016, the carrying amount of our liability for settlement obligations under the Plea Agreement was $60 million, recorded in 
other current liabilities.  In the years ended December 31, 2017, 2016 and 2015, we made cash payments of $60 million in each period, 
representing the final installments for our obligations under the Plea Agreement. 

Consent Decree—Under  the  civil  consent  decree  (the  “Consent Decree”),  we  agreed  to  undertake  certain  actions,  including 
enhanced safety and compliance actions when operating in U.S. waters.  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.  The 
Consent Decree resolved the claim by the U.S. for civil penalties under the CWA.  We may request termination of the Consent Decree after 
January 2, 2019, provided we meet certain conditions.  We also agreed to pay civil penalties of $1.0 billion plus interest.  In the year ended 
December 31,  2015,  we  made  a  cash  payment  of  $204 million,  including  interest,  representing  the  final  installment  due  under  the 
Consent Decree. 

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 escrow accounts 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 accounts for payment of attorneys’ fees.  At December 31, 2017 and 2016, the aggregate 
balance in escrow was $212 million and $237 million, respectively, recorded in restricted cash accounts and investments. 

Other legal proceedings 

Asbestos  litigation—In  2004,  several  of  our  subsidiaries  were  named,  along  with  numerous  other  unaffiliated  defendants,  in 
complaints filed in the Circuit Courts of the State of Mississippi, and in 2014, a group of similar complaints were filed in Louisiana.  The 
plaintiffs, former employees of some of the defendants, generally allege that the defendants used or manufactured asbestos containing 
drilling mud additives for use in connection with drilling operations, claiming negligence, products liability, strict liability and claims allowed 
under the Jones Act and general maritime law.  The plaintiffs generally seek awards of unspecified compensatory and punitive damages, 
but the court appointed special master has ruled that a Jones Act employer defendant, such as us, cannot be sued for punitive damages.  
At December 31, 2017, eight 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, 2017, the subsidiary was a defendant in 
approximately 140 lawsuits with a corresponding number of plaintiffs.  For many of these lawsuits, we have not been provided with 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 and its operations were discontinued in 1989, 
and the subsidiary has no remaining assets other than insurance policies, rights and proceeds, including (i) certain policies subject to litigation 
and (ii) certain rights and proceeds held directly or indirectly through a qualified settlement fund.  The subsidiary has in excess of $1.0 billion 

AR-81 

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

in insurance limits potentially available to the subsidiary.  Although not all of the policies may be fully available due to the insolvency of certain 
insurers,  we  believe  that  the  subsidiary  will  have  sufficient  funding  directly  or  indirectly,  including  from  settlements  and  payments  from 
insurers, assigned rights from insurers and coverage-in-place settlement agreements with insurers to respond to these claims.  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. 

Rio de Janeiro tax assessment—In the year ended December 31, 2006, the state tax authorities of Rio de Janeiro in Brazil 
issued to one of our subsidiaries tax assessments on equipment imported into the state in connection with our operations, resulting from a 
preliminary  finding  by  these  authorities  that  our  record  keeping  practices  were  deficient.    At  December 31,  2017,  the  aggregate  tax 
assessment was for BRL 529 million, equivalent to approximately $160 million, including interest and penalties.  In September 2006, we filed 
an initial response refuting these tax assessments, and, in September 2007, the state tax authorities confirmed that they believe the tax 
assessments are valid.  On September 27, 2007, we filed an appeal with the state Taxpayer’s Council contesting the assessments.  In 
November 2017, the Third Chamber of the Taxpayer’s Council for administrative proceedings ruled in our favor on the validity of the initial 
tax claims.  The ruling is subject to appeal by the state tax authorities.  While we cannot predict or provide assurance as to the final outcome 
of these proceedings, 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. 

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 a waiver from the requisite lenders, result in an event of default under our currently undrawn Five-Year 
Revolving 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. 

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 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. 

Other environmental matters 

Hazardous  waste  disposal  sites—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. 

We have 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 have agreed with the Environmental Protection Agency (the “EPA”) and the DOJ to settle our potential liabilities 
for  this  site  by  agreeing  to  perform  the  remaining  remediation  required  by  the  EPA.    The  parties  to  the  settlement  have  entered  into  a 
participation agreement, which makes us liable for approximately eight percent of the remediation and related costs.  The remediation is 
complete, and we believe our share of the future operation and maintenance costs of the site is not material.  There are additional potential 
liabilities related to the site, but these cannot be quantified, and we have no reason at this time to believe that they will be material. 

AR-82 

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

One of our subsidiaries has been 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 by the 
EPA as PRPs.  The current property owner, an unrelated party, performed the required testing and detected no contaminants.  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.  Based on the 
test results, we would contest any potential liability.  We have no knowledge at this time 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.    These 
investigations  involve  determinations  of  (a) the  actual  responsibility  attributed  to  us  and  the  other  PRPs  at  the  site,  (b) appropriate 
investigatory or remedial actions and (c) allocation of the costs of such activities among the PRPs and other site users.  Our ultimate financial 
responsibility in connection with those sites may depend on many factors, including (i) the volume and nature of material, if any, contributed 
to the site for which we are responsible, (ii) the number of other PRPs and their financial viability and (iii) the remediation methods and 
technology to be used. 

It  is  difficult  to  quantify  with  certainty  the  potential  cost  of  these  environmental  matters,  particularly  in  respect  of  remediation 
obligations.  Nevertheless, based upon the information currently available, we believe that our ultimate liability arising from all environmental 
matters, including the liability for all other related pending legal proceedings, asserted legal claims and known potential legal claims that are 
likely to be asserted, is adequately accrued and should not have a material effect on our consolidated statement of financial position, results 
of operations or cash flows.

Accordingly,  we  present  the  carrying  amount  of  Angco  Cayman’s  ownership  interest  as  redeemable  noncontrolling  interest  on  our 
consolidated balance sheets.  Changes in redeemable noncontrolling interest were as follows (in millions):

Transocean Partners—Transocean  Partners LLC,  a  Marshall  Islands  limited  liability  company  and  a  wholly  owned  indirect 
subsidiary  (“Transocean Partners”),  was  previously  a  partially  owned  subsidiary.    In  the  years  ended  December 31,  2016  and  2015, 
Transocean Partners declared and paid an aggregate distribution of $99 million and $100 million, respectively, to its unitholders, of which 
$28 million and $29 million, respectively, was paid to the holders of noncontrolling interest.  On December 9, 2016, 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  a wholly  owned  indirect  subsidiary  of  Transocean Ltd.    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. 

Note 12—Shareholders’ Equity 

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. 

Distributions of qualifying additional paid-in capital—In May 2015, at our annual general meeting, our shareholders approved 
the distribution  of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $0.60 per outstanding share, 
payable in four quarterly installments of $0.15 per outstanding share, subject to certain limitations.  In May 2015, we recognized a liability of 
$218 million for the distribution payable, recorded in other current liabilities, with a corresponding entry to additional paid-in capital.  On 
June 17 and September 23, 2015, we paid the first two installments in the aggregate amount of $109 million to shareholders of record as of 
May 29 and August 25, 2015.  On October 29, 2015, at our extraordinary general meeting, our shareholders approved the cancellation of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

the third and fourth installments of the distribution.  As a result, we reduced our distribution payable, recorded in other current liabilities, by 
$109 million with corresponding increase to additional paid-in capital. 

In May 2014, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in 
the form of a U.S. dollar denominated dividend of $3.00 per outstanding share, payable in four quarterly installments of $0.75 per outstanding 
share, subject to certain limitations.  On March 18, 2015, we paid the final installment in the aggregate amount of $272 million to shareholders 
of record as of February 20, 2015. 

We did not pay the distribution of qualifying additional paid-in capital with respect to our shares held by our subsidiary or previously 

held in treasury. 

Shares  issued—To  complete  the  merger  with  Transocean Partners,  in  December  2016,  we  issued  23.8 million  shares  from 
conditional capital.  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.    See  Note 1—Business, 
Note 11—Noncontrolling Interest, Note 15—Supplemental Cash Flow Information and Note 20—Subsequent Event. 

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—Two of our subsidiaries hold 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, 2017 and 2016, our 
subsidiaries held 3.6 million shares and 5.4 million shares, respectively.

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.  As of December 31, 2017, under the current plan established in 2015, we had 20.7 million shares 
authorized and 9.9 million shares available to be granted under the Long-Term Incentive Plan.  As of December 31, 2017, total unrecognized 
compensation costs related to all unvested share-based awards were $43 million, which are 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.  At the end of the measurement period, 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 and stock appreciation rights 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 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 short maturities of the instruments.  At December 31, 2017 and 2016, the 
aggregate carrying amount of our cash equivalents was $2.1 billion and $2.6 billion, respectively. 

Short-term investments—The carrying amount of 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 short 
maturities of the instruments. 

Restricted  cash  accounts  and  investments—The  carrying  amount  of  the  cash  and  cash  equivalents  that  are  subject  to 
restrictions due to collateral requirements, legislation, regulation or court order approximates fair value due to the short term nature of the 
instruments in which the restricted cash balances are held.  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.  At 
December 31, 2016, the aggregate carrying amount of such restricted cash and cash equivalents was $387 million, including $368 million 
and $19 million recorded in current assets and other assets, respectively. 

The carrying amount of the restricted cash investments pledged for debt service of the Eksportfinans Loans due January 2018 and 
for security of certain other credit arrangements represents the amortized historical cost of the investment.  We measured the estimated fair 
value of such restricted cash investments using significant other observable inputs, representative of a Level 2 fair value measurement, 
including the terms and credit spreads of the instruments.  At December 31, 2017 and 2016, the aggregate carrying amount of the restricted 
cash investments was $33 million and $123 million, respectively.  At December 31, 2017 and 2016, the estimated fair value of such restricted 
cash investments was $33 million and $124 million, respectively. 

Debt—We measured the estimated fair value of our debt, all of which was fixed-rate debt, using significant other observable inputs, 

representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. 

Note 17—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. 

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

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 18—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,  2017,  we  had  approximately  4,900 employees,  including  approximately  400 persons 
engaged through contract labor providers.  Approximately 26 percent of our total workforce, working primarily in Brazil, Norway and the U.K. 
are represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially all of which are 
subject to annual salary negotiation.  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 18—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.

(a)  Other  countries  represents  countries  in  which  we  operate  that  individually  had  long-lived  assets  representing  less  than 

10 percent of consolidated long-lived assets. 

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, 2017 
and 2016, the aggregate carrying amount of our long-lived assets located in Switzerland was less than $1 million and $2 million, respectively. 

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.

Royal Dutch Shell plc (together with its affiliates, “Shell”) and Petróleo Brasileiro S.A. (“Petrobras”) accounted for approximately 29 percent,

(a)  Second quarter and third quarter included an aggregate loss of $1.4 billion associated with the impairment of certain drilling units classified as assets 
held for sale.  Second quarter included a loss of $94 million associated with the impairment of our midwater floater asset group.  Second quarter 
included  a  loss  of  $1.6 billion  associated  with  the  sale  of  10 high-specification  jackups  and  the  novation  of  five high-specification  jackups  under 
construction.  First quarter, second quarter, third quarter and fourth quarter included an aggregate loss of $55 million associated with the retirement of 
debt. 

(b)  First quarter, second quarter, third quarter and fourth quarter included an aggregate loss $41 million associated with the impairment of certain drilling 
units classified as assets held for sale.  Fourth quarter included a loss of $52 million associated with the impairment of our deepwater asset group.  
Fourth quarter  included  income  of  $30 million  associated  with  recoveries  of  previously  incurred  costs  associated  with  the  Macondo well  incident.  
Second quarter and third quarter included a gain of $38 million and $110 million, respectively, associated with the retirement of debt.  See Note 5—
Drilling Fleet, Note 8—Debt and Note 10—Commitments and Contingencies.  

Note 20—Subsequent Event 

Business  combination—On  August 13,  2017,  we  entered  into  the  Transaction Agreement  with  Songa  pursuant  to  which  we 
agreed to offer to acquire all of the issued and outstanding shares of Songa through the Offer in exchange for consideration per Songa share, 
consisting of (i) 0.3572  newly issued shares of Transocean Ltd. and (ii) approximately $2.99726  principal amount of 0.5% Exchangeable 
Senior Bonds due January 2023 (the “Exchangeable Bonds”) to be issued by Transocean Inc., our wholly owned direct subsidiary and a 
Cayman Islands exempted company.  Additionally, each Songa shareholder could elect to receive a cash payment of NOK 47.50 per Songa 
share up to a maximum of NOK 125,000 per shareholder in lieu of some or all of the consideration such shareholder would otherwise be 
entitled to receive in the Offer. 

We believe the acquisition of Songa strengthens and solidifies our position as a leader in harsh environment and ultra-deepwater 
drilling services by adding significant high value assets, including four high-specification harsh environment floaters, supported by significant 
contract backlog.  Additionally, the acquisition strengthens our footprint in harsh environment operating areas and our existing relationship 
with Statoil ASA. 

In connection with the acquisition, shareholders at our extraordinary general meeting, on 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

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

of our authorized share capital and our shares issuable upon exchange of 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, and we issued 
66.9 million shares with an aggregate market value of $735 million, equivalent to $10.99 per share, estimated based on the market value of 
our shares on the date of issuance to shareholders of Songa as partial consideration for the acquired Songa shares.  Additionally, we made 
an aggregate cash payment of less than $1 million to Songa shareholders that elected to receive a cash payment. 

We  also  issued  an  aggregate  principal  amount  of  $854 million  of  the  Exchangeable  Bonds  as  partial  consideration  for  the 
acquisition  of  the  acquired  Songa  shares  and  partial  settlement  of  certain  Songa  indebtedness.    Transocean Inc.  is  the  issuer  of  the 
Exchangeable Bonds, which are fully and unconditionally guaranteed by Transocean Ltd. and rank equally with our other senior unsecured 
debt.  We will pay interest on the Exchangeable Bonds semiannually, commencing July 30, 2018.  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. 

By  March 31,  2018,  we  expect  to  complete  the  acquisition  of  the  remaining  shares  not  owned  by  us  through  a  compulsory 
acquisition, which is available to us under Cyprus law.  In connection with the compulsory acquisition, we expect to issue 1.6 million shares 
and an aggregate principal amount of $13 million of the Exchangeable Bonds as consideration for the remaining Songa shares.  We have 
not  completed  our  preliminary  allocation  of  the  acquisition  price  to  the  assets  acquired  and  liabilities  assumed  given  the  timing  of  the 
acquisition date, on January 30, 2018, relative to the date of issuance of our financial statements as of and for the year ended December 31, 
2017.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

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

statements or in any period subsequent to such date. 

Item 9A. 

Controls and Procedures 

Disclosure controls and procedures—Our disclosure controls and procedures are designed to provide reasonable assurance 
that information required to be disclosed in our reports filed or submitted under the Exchange Act is (1) accumulated and communicated to 
our management, including our Chief Executive Officer 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, 2017. 

Internal  control  over  financial  reporting—In  our  annual  report  for  the  year  ended  December 31,  2016,  we  identified  and 
disclosed a material weakness in the execution of our controls over the application of the accounting literature to the measurement of deferred 
taxes.  The material weakness was specifically related to the following: (1) the remeasurement of certain nonmonetary assets in Norway, 
(2) the  analysis  of  our  U.S.  defined  benefit  pension  plans  and  effect  on  other  comprehensive  income  and  (3) the  assessment  of  the 
realizability of our deferred tax assets, and the need for valuation allowances. 

To remediate the identified material weakness, we implemented the following improvements to enhance our overall financial control 
environment: (1) we added additional personnel and external resources with the appropriate level of tax accounting expertise and invested 
in  additional  technical  tax  accounting  training,  (2) we  standardized  our  documentation  and  communication  protocols  and  integrated  our 
processes within and between tax and other key departments, and (3) we expanded the use of systems and automated certain processes.  
Prior to the issuance of this annual report, we successfully completed the testing of these enhanced controls and concluded that the material 
weakness had been remediated as of December 31, 2017. 

Except as described above, there has been no change to our internal control over financial reporting during the quarter ended 
December 31, 2017 that has materially affected or is reasonably likely to materially affect our internal control over financial reporting.  See 
“Management’s  Report  on  Internal  Control  Over  Financial  Reporting”  and  “Report  of  Independent  Registered  Public  Accounting  Firm,” 
included in Item 8 of this annual report.

To the General Meeting of  

Transocean Ltd., Steinhausen  

Zurich, February 21, 2018 

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, 2017. 

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,  2017  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 accompanying 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.

NOTES TO STATUTORY FINANCIAL STATEMENTS 

Note 1—General 

Transocean Ltd. (the “Company”, “we”, “us”, or “our”) is the parent company of Transocean Inc., Transocean Management Ltd., 
and Transocean Management Services GmbH., our 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, 2017 and 2016, we had less than 
10 full-time employees. 

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 

Average exchange rates

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.

On May 30, 2016, we sold Transocean Services AS to one of our indirect subsidiaries and, accordingly, it is no longer our direct 
investment.    On  October 4,  2016,  we  contributed  capital  of  CHF 18,000  for  90 percent  quota  to  form  Transocean  Management 
Services GmbH to perform management and administration services. 

Impairments—In the year ended December 31, 2017, as a result of our annual impairment test, we determined that the carrying 
amounts of our investments in subsidiaries were impaired, and, as a result, we recognized an aggregate loss of CHF 440 million and released 
excess reserves in amount of CHF 511 million associated with the impairment of our investment in Transocean Inc.  In the  year ended 
December 31, 2016, as a result of our annual impairment test, we determined that the carrying amounts of our investments in subsidiaries 
were not impaired.

Authorized share capital—In May 2014, at our annual general meeting, our shareholders approved an authorized share capital 
in the amount of CHF 337 million, authorizing the issuance of a maximum of 22.5 million fully paid-in shares with a par value of CHF 15 per 
share at any time until May 16, 2016.  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.  Consequently, the previously approved authorized 
share capital in the amount of CHF 337 million has been reduced to CHF 2 million, authorizing the issuance of a maximum of 22.2 million 
fully paid-in shares with a par value of CHF 0.10 per share.  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. 

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  without  obtaining  additional  shareholder  approval.    The  shares  may  be  issued  under  the  following 
circumstances: 

(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 
the advance subscription rights of shareholders are excluded. 

On July 31, 2016, we and TPHL entered into an option agreement, as amended on November 22, 2016, pursuant to which we 
granted TPHL the right to acquire from us a number of our shares in connection with its merger with TPLLC, pursuant to which, the publicly 
held common units of TPLLC not owned by TPHL were exchanged for the right to receive our shares.  On December 6, 2016, TPHL exercised 
its right to receive 23.8 million of our shares, which we issued from our conditional share capital, and paid to us USD 318 million, as required 
under the option agreement.  Following the completion of the merger, TPHL held 95,830 of our shares. 

Qualified capital loss—As presented on our interim balance sheet, dated July 31, 2015, included in our proxy statement for our 
extraordinary general meeting on October 29, 2015, we determined that our net assets cover less than 50 percent of our statutory share 
capital and statutory capital reserves.  Under Swiss law, the board of directors convened a general meeting of shareholders and proposed

measures that remediate such capital loss.  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 and allocated CHF 3.75 billion of the 
aggregate  par  value  reduction  amount  to  reduce  our  accumulated  net  loss.    Effective  January 7,  2016,  our  qualified  capital  loss  was 
effectively remediated upon establishment of a public deed of compliance for our par value reduction and registration in the commercial 
register. 

Note 5—Own Shares 

Overview—The following is a summary of changes in the registered shares (i) that were repurchased under our share repurchase

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, 
equivalent  to  approximately  USD 3.4 billion.    At  December 31  2015,  we  held  2.9 million  of  our  shares,  repurchased  under  the  share 
repurchase program, with an aggregate carrying amount of CHF 257 million.  On October 29, 2015, at our extraordinary general meeting, 
our  shareholders  approved  the  cancellation  of  all  shares  that  had  been  repurchased  under  the  share  repurchase  program.    Effective 
January 7, 2016, such shares were cancelled upon registration in the commercial register.  

Shares held by subsidiaries—Transocean Inc. and TPHL hold our shares to satisfy our obligations to deliver shares in connection 
with awards granted under our incentive plans or other rights to acquire our shares.  In the year ended December 31, 2017 and 2016, we 
transferred  1.9 million  and  1.6 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, 2017 and 2016, we received cash proceeds of 
less than CHF 1 million, in connection with own shares transferred in exchange for equity awards exercised or withheld for taxes under our 
share-based compensation plans.

TRANSOCEAN LTD. 
NOTES TO STATUTORY FINANCIAL STATEMENTS—continued 

Note 7—Guarantees and Commitments 

Transocean Inc. and other indirect subsidiaries debt obligations—Transocean Inc., Transocean Phoenix 2 Limited (“TP2L”) 
and Transocean Proteus Limited (“TPTL”) have each issued certain debt securities or entered into other debt instruments, including notes, 
revolving credit facilities, debentures, surety bonds and letters of credit.  We have guaranteed certain of these debt securities or other debt 
instruments.  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, 2017 and 2016, the aggregate carrying amount of debt that we have guaranteed was USD 6.2 billion and USD 7.5 billion, 
respectively, equivalent to approximately CHF 6.0 billion and CHF 7.6 billion, respectively.  See Note 10—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 (the “Plea Agreement”), 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 (the “EPA”) 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, under the terms of the Plea Agreement and the Consent Decree, 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  guaranteed  the  scheduled  installments  and  other  obligations  required  of  the  Transocean 
Defendants under the Plea Agreement and the Consent Decree.  In connection with our guarantee, the Transocean Defendants agreed to 
pay to us a guarantee fee.  The guarantee fee is paid annually, beginning on January 1, 2014 through 2018, and is equivalent to 1.76 percent 
of the weighted average daily outstanding balance due by the Transocean Defendants over the prior year.  In the years ended December 31, 
2017 and 2016, we recognized guarantee fee income of less than CHF 1 million and CHF 2 million, respectively. 

On February 25, 2013, certain of our subsidiaries (the “Respondents”) and the EPA entered into an administrative agreement (the 
“EPA Agreement”).  The EPA Agreement resolved all matters relating to suspension, debarment and statutory disqualification arising from 
the matters contemplated by the Plea Agreement.  We guaranteed the compliance obligations required of the Respondents under the EPA 
Agreement.  In 2016, Transocean approached the EPA Suspension and Debarment Division (“EPA SDD”) to request the early termination 
of  the  EPA Agreement  in  light  of  Transocean’s  successful  performance  of  its  obligations  under  the  EPA Agreement.    After  discussions 
between Transocean and the EPA SDD in 2016 and early 2017, the EPA Suspension and Debarment Official granted Transocean’s request.  
The EPA Agreement was terminated effective as of June 21, 2017. 

Norway tax investigations and trial—Norwegian civil tax authorities previously challenged certain transactions undertaken by 
our subsidiaries in 1999, 2001 and 2002.  On June 26, 2014, the Norwegian district court in Oslo ruled that our subsidiary was liable for the 
civil tax assessment but waived all penalties and interest.  On January 9, 2017, the Norwegian appeal court in Oslo ruled entirely in favor of 
the  Transocean  subsidiaries  and  overturned  the  district  court  with  respect  to  the  remaining  question  of  principal  tax  obligations.    On 
February 10, 2017, the tax authorities filed an appeal with the Norwegian Supreme Court.  On June 16, 2017, the Norwegian Supreme Court 
rejected the appeal, formally closing the dispute in favor of our subsidiaries. 

Transocean Management Ltd. office lease obligation—Transocean Management Ltd., has a continuing lease obligation 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,  2017  and  2016,  our  guarantee  for  the  Transocean  Management Ltd.  lease  obligation  was 
CHF 460,000. 

Note 8—Contingencies 

U.S. Gulf of Mexico Macondo well incident—On April 22, 2010, the ultra-deepwater floater Deepwater Horizon, a rig owned and 
operated by certain of our indirect wholly owned subsidiaries (the “Macondo Subsidiaries”), sank after a blowout of the U.S. Gulf of Mexico 
Macondo well caused a fire and explosion on the rig off the coast of Louisiana.  The Macondo Subsidiaries have been named in lawsuits 
related to the Macondo well incident.  A significant portion of the contingencies arising from the Macondo well incident has now been resolved 
or is pending release of funds from escrow.  We believe the most notable remaining claims against the Macondo Subsidiaries arising from 
the Macondo well incident are the 30 settlement class opt outs from the PSC Settlement Agreement. 

Federal securities claims—On September 30, 2010, a proposed federal securities class action was filed against us in the U.S. 
District Court for the Southern District of New York.  In the action, a former shareholder of the acquired company alleged that the joint proxy 
statement relating to our shareholder meeting in connection with the merger with the acquired company violated various securities laws and 
that  the  acquired  company’s  shareholders  received  inadequate  consideration  for  their  shares  as  a  result  of  the  alleged  violations.    On 
March 11, 2014, the District Court for the Southern District of New York dismissed the claims as time-barred.  Plaintiffs appealed to the U.S. 
Court of Appeals for the Second Circuit (the “Second Circuit”), but on March 17, 2016, the Second Circuit affirmed the dismissal.  Plaintiffs 
filed a petition for writ of certiorari with the U.S. Supreme Court on August 12, 2016.  On June 27, 2017, the petition was denied and the 
dismissal is now final.

NOTES TO STATUTORY FINANCIAL STATEMENTS—continued 

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 9—Related Party Transactions 

Transocean Inc. and Transocean Partners Holdings Limited—Transocean Inc. and TPHL hold 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, 2017 and 2016, Transocean Inc. and TPHL held 3.6 million and 5.4 million of our shares, respectively. 

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,  2017  and  2016,  we  had  borrowings  of  USD 53.2 million  and 
USD 7.2 million,  respectively,  equivalent  to  approximately  CHF 52.2 million  and  CHF 7.3 million,  respectively,  outstanding  under  the 
revolving credit facility.  At December 31, 2017 and 2016, the variable interest rate on the outstanding borrowings was 2.50 percent and 
2.25 percent, respectively. 

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, 2017 and 2016, we recognized such costs of CHF 10 million and CHF 15 million, respectively, 
recorded in general and administrative costs and expenses. 

Note 10—Subsequent Events 

Business combination— On August 13, 2017, we entered into the Transaction Agreement with Songa Offshore SE, a European 
public company limited by shares, or societas Europaea, existing under the laws of Cyprus (“Songa”), pursuant to which we agreed to offer 
to acquire all of the issued and outstanding shares of Songa through the Offer in exchange for consideration per Songa share, consisting of 
(i) 0.3572   newly  issued  shares  of  Transocean Ltd.  and  (ii) approximately  USD 2.99726   principal  amount  of  0.5% Exchangeable  Senior 
Bonds due January 2023 (the “Exchangeable Bonds”) to be issued by Transocean Inc.  Additionally, each Songa shareholder could elect to 
receive a cash payment of NOK 47.50 per Songa share up to a maximum of NOK 125,000 per shareholder in lieu of some or all of the 
consideration such shareholder would otherwise be entitled to receive in the Offer. 

In connection with the acquisition, shareholders at our extraordinary general meeting, on January 16, 2018, were requested to 
consider the following: (1) the issuance of up to 68.6 million of our 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 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, and we issued 
66.9 million shares with an aggregate market value of USD 735 million, equivalent to USD 10.99 per share, estimated based on the market 
value of our shares on the date of issuance to shareholders of Songa as partial consideration for the acquired Songa shares.  Additionally, 
we made an aggregate cash payment of less than USD 1 million to Songa shareholders that elected to receive a cash payment. 

Transocean Inc. also issued an aggregate principal amount of USD 854 million of the Exchangeable Bonds as partial consideration 
for the acquisition of the acquired Songa shares and partial settlement of certain Songa indebtedness.  Transocean Inc. is the issuer of the 
Exchangeable Bonds, which are fully and unconditionally guaranteed by us.  Holders of the Exchangeable Bonds may convert the notes into 
our shares under certain circumstances at a rate of 97.29756 shares per USD 1,000 note, equivalent to a conversion price of USD 10.28 per 
share, subject to adjustment due to the occurrence of certain events. 

By  March 31,  2018,  we  expect  to  complete  the  acquisition  of  the  remaining  shares  not  owned  by  us  through  a  compulsory 
acquisition, which is available to us under Cyprus law.  In connection with the compulsory acquisition, we expect to issue 1.6 million shares 
and Transocean Inc. is expected to issue an aggregate principal amount of USD 13 million of the Exchangeable Bonds as consideration for 
the remaining Songa shares. 

Significant shareholders—Subsequent to December 31, 2017, in connection with the Songa acquisition, we issued our shares 
to Songa shareholders as partial consideration for their shares.  As of January 31, 2018, as a result of the transaction, Frederick W. Mohn, 
a newly elected member of our board of directors held, directly and indirectly through Perestroika AS, 31.1 million shares, which represented 
approximately 6.74% of our issued capital, based on our 461.7 million total shares issued as of such date.

We are a leading international provider of offshore contract drilling services for oil and gas wells. As of

& Poor’s MidCap 400 Index (“S&P MidCap 400”) and the Upstream Index 
prepared by Simmons & Company International, Energy Specialists of Piper 
Jaffray (“SCI”) 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 on December 31, 2012, and that all dividends were 
reinvested on the date of payment. The SCI represents the price movement  
of the index.
