We are a leading international provider of offshore contract drilling services for oil and gas wells. As of February
11, 2016, we own or have partial ownership interests in, and operate a fleet of 61 mobile offshore drilling units. In
addition, we have six newbuild ultra-deepwater drillships and five newbuild high-specification jackups under con-
struction or under contract to be constructed. We specialize in technically demanding sectors of the global offshore
drilling business with a particular focus on 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 and on the SIX Swiss Exchange
(“SIX”) under the symbol RIGN. We have elected to delist from the SIX effective March 31, 2016, with the last
trading day scheduled for March 30, 2016.

The rig symbols in the map above represent the company’s global market presence as of the February 11, 2016, Fleet Status Report.

ABOUT THE COVER: The cover features our latest addition to the fleet - the high-specification, ultra-deepwater drillship Deepwater Thalassa. 
The floater commenced its 10-year contract with Shell in the U.S. Gulf of Mexico in the first quarter of 2016. The back cover features a
Transocean employee onboard the rig.

Letter to Shareholders 

Our 2015 financial results exceeded both internal and external expectations, and were the direct result of our 

continued commitment to operational excellence, and our heightened focus around organizational and operational 
efficiency. While we are pleased with our 2015 performance, we enter 2016 facing an extremely challenging 
environment. Oil prices have fallen to levels not seen in more than a decade, driven primarily by global concerns around 
supply and demand imbalances. As a result, our customers continue to significantly curtail both their exploration and 
development activities, resulting in a limited number of near-term offshore drilling prospects. In response, we are taking 
the necessary steps to maintain our market leadership position through this downturn, and position ourselves to emerge 
even stronger and leaner when the recovery occurs. 

We are in a solid position financially. We will continue generating operating cash flow from our market 

leading $15.5 billion backlog as of February 11, 2016, which is backed by strong contracts, and primarily comprised of 
investment grade customers. Additionally, with over $2 billion of cash as we enter 2016, and an undrawn, unsecured 
revolving credit facility of $3 billion, we have sufficient liquidity to fulfill our existing commitments, with optionality to 
evaluate and potentially pursue value-enhancing transactions, which could materialize in the current market. 

We continue to high-grade our fleet. We have recently added two new ultra-deepwater drillships, the 
Deepwater Thalassa, and the Deepwater Proteus, to our fleet of world-class assets. Both of these rigs have firm 10-year 
contracts with Shell. Additionally, we will add a third ultra-deepwater drillship, the Deepwater Conqueror, to our fleet 
later in the year that will commence a five-year contract with Chevron. While welcoming these new high-specification 
rigs into our fleet, we will continue to objectively evaluate the capability and marketability of our existing fleet. For 
those assets that do not support our objective of operating the most competitive assets in the industry, we will remove 
them from the fleet, and recycle them in accordance with existing regulations and Transocean’s best practices. And, for 
those assets that are integral to our future portfolio, but are not currently contracted, we will continue to stack them in a 
way that reduces costs, but allows for timely and cost-effective re-activation when market demand returns. 

We continue to execute our commercial and operational strategy, which includes supporting our customers in 

the delivery of safer and more efficient offshore well solutions. In 2015, we continued to drive year-over-year 
improvements in our safety performance, rig uptime and revenue efficiency. In fact, we have become sufficiently 
confident in the quality and consistency of our performance that we are entering into incentivized contracts that align us 
with our customers’ objectives, and reward us for delivering safer, faster, and more cost-effective wells. Our customers 
are responding favorably to our performance and our commercial model and have awarded us several new contracts in 
this highly competitive market. Our ability to continue to perform to these elevated expectations ultimately enhances our 
market position and shareholder value. 

We continue to define and implement innovative plans to remove cost from our business, while improving 

our operating performance. In 2015, we outperformed our internal targets and expectations for critical operating 
metrics, while meaningfully reducing our cost structure. As we have rationalized our fleet, and re-focused our operations 
on the deepwater markets and other areas that require high-specification assets and capabilities, we have respectively 
right-sized our support, and streamlined our processes, removing considerable shore-based costs. We also continue to 
realize opportunities to more efficiently maintain our equipment, manage shipyard projects, stack uncontracted assets 
and recycle less marketable assets. 

Although this market is the most challenging that we have seen in 30 years, we believe that the cyclical nature 
of this industry will ultimately bring forth a recovery that will drive incremental demand for our industry-leading assets 
and services. Until that time, we will continue to enhance our position by cultivating strong customer relationships, 
introducing innovative new commercial models that are more aligned with our customers’ objectives, consistently 
delivering safer and more efficient campaigns, continuing to streamline our business, and leveraging the strength of our 

 
 
 
 
 
balance sheet to capitalize on strategic opportunities as and when appropriate.     

We want to thank you, our shareholders, on behalf of our entire team at Transocean, and let you know your trust 

in our ability to run this great company is both appreciated and well-placed. 

Sincerely, 

Merrill A. “Pete” Miller, Jr.

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, Martin B. McNamara and Tan Ek Kia as members of the Compensation Committee (Agenda Item 7) to serve 

iv 

 
 
 
 
 
 
 
until  completion  of  the  2017  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 no longer permitted to appoint a corporate representative to 
act  as  the  proxy  for  purposes  of  voting  at  the  2016  Annual  General  Meeting.  Swiss  companies  may  only  appoint  an 
independent proxy for these purposes. At the 2015 Annual General Meeting, shareholders elected Schweiger Advokatur / 
Notariat to serve as our independent proxy for the 2016 Annual General Meeting. Agenda Item 8 asks that you again elect 
this firm to act as the independent proxy for the 2017 Annual General Meeting and any extraordinary general meeting of 
shareholders of the Company that may be held prior to the 2017 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 2016 Annual General Meeting 
and the 2017 Annual General Meeting (Agenda Item 11A) and the maximum aggregate amount of compensation of the 
Executive Management Team for fiscal year 2017 (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 
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 
√  Conduct  an  annual  review  of  our  compensation  strategy, 
including a review of our compensation-related risk profile 
√  Mandate meaningful share ownership requirements for our 

executives 

√  Maintain a claw-back policy that allows for the forfeiture, 
recovery  or  adjustment  of  incentive  compensation  paid  to 
executives  due  to  a  material  misstatement  of  financial 
results 

√  Base incentive payments on quantitative metrics 

√  Maintain  compensation  plans  designed 
compensation 

program  with 

to  align  our 
long-term 

executive 
shareholder interests 

√  Link long-term incentive compensation to both relative and 

absolute performance metrics 
√  Deliver  one-half  (50%)  of 

performance-based equity awards 

long-term 

incentives 

in 

What We Don’t Do 
X Allow  our  executives  to  hedge,  sell  short  or  hold  derivative 
instruments tied to our shares (other than options issued by us) 

X Allow our executives or directors to pledge Company shares   

compensation 

X Have pre-arranged individual severance agreements or special 
any 
change-in-control 
Executive Officers; however, subject to the limitations under the 
Minder Ordinance pursuant to which severance cannot be paid 
to  members  of  our  Executive  Management  Team,  our 
executives  are  eligible  for  severance  and  change-in-control 
provisions pursuant to our policies 

agreements  with 

X Maintain single-trigger change-in-control provisions or change-

in-control gross-ups 

X Guarantee salary increases, non-performance based bonuses or 

unrestricted equity compensation 

X Provide any payments or reimbursements for tax equalization 

X Pay dividend equivalents on performance share units that have

(1)  Affirmative vote of a relative majority of the votes cast in person or by proxy at the 2016 Annual General Meeting. 
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 two-thirds of the votes represented at the 2016 Annual General Meeting. An abstention, broker 

non-vote (if any) or blank or invalid ballot will have the effect of a vote “AGAINST” this proposal. 

(3)  Affirmative  vote  of  a  plurality  of  the  votes  cast  in  person  or  by  proxy  at  the  2016  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. 

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

Outstanding Shares 

As of  March 1, 2016,  there were 365,066,026  Transocean Ltd.  shares outstanding, which  excludes 5,901,356

“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 
instructions from customers for these non-routine or contested matters are referred to as “broker non-votes.” The following 
matters are non-routine matters under NYSE Rules:

forth above and may not be able to vote your shares on other matters at the 2016 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 instruct the independent proxy to vote in accordance

voting is permissible under Swiss law are properly presented at the 2016 Annual General Meeting for consideration, 
you instruct the independent proxy, in the absence of other specific instructions, to vote in accordance with the 
recommendations of the Board of Directors.

AGENDA ITEM 1

Transocean Ltd. for Fiscal Year 2015 and the Audited Statutory Financial Statements of Transocean Ltd. for 
Fiscal Year 2015. 

Proposal of the Board of Directors 

The  Board  of  Directors  proposes  that  the  2015  Annual  Report,  including  the  audited  consolidated  financial 
statements of Transocean Ltd. for fiscal year 2015 and the audited statutory financial statements of Transocean Ltd. for 
fiscal year 2015, be approved. 

Explanation 

The  audited  consolidated  financial  statements  of  Transocean Ltd.  for  fiscal  year  2015  and  the  audited  Swiss 
statutory financial statements of Transocean Ltd. for fiscal year 2015 are contained in the 2015 Annual Report, which,

these materials will be available for physical inspection at the Company’s registered office, Turmstrasse 30, CH-6300 Zug,

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 2015 and statutory financial 
statements for fiscal year 2015. 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, 2015, be approved. 
Ernst & Young Ltd expresses its opinion that the “consolidated financial statements for the years ended December 31, 
2015 and 2014 present fairly in all material respects the consolidated financial position of Transocean Ltd. and subsidiaries 
at December 31, 2015 and 2014, and the consolidated results of operations and cash flows for each of the three years in 
the period ended December 31, 2015, 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 the year ended December 31, 2015, 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.

AGENDA ITEM 2 

Discharge of the Members of the Board of Directors and the Executive Management Team from Liability for 
Activities During Fiscal Year 2015. 

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 Mey, John B. Stobart, Ian C. Strachan, Steven L. Newman and Esa Ikaheimonen, who served as members of our 
Executive Management Team in 2015, be discharged from liability for activities during fiscal year 2015.   

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 the directors or executive management with respect to activities 
during fiscal year 2015. 

Recommendation 

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

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  2016  Annual  General  Meeting  is  the 
accumulated loss of Transocean Ltd., on a standalone basis. 

At our Extraordinary General Meeting held on October 29, 2015, shareholders approved (1) a reduction of the 
par value of each share of the Company from CHF 15 to CHF 0.10, (2) the use of CHF 3.75 billion of the aggregate par 
value reduction amount to reduce the Company’s total accumulated loss as recorded on its Swiss statutory balance sheet, 
and (3) the allocation of CHF 1,820,076,670.10 of the aggregate par value reduction amount to the Company’s statutory 
capital reserves from capital contribution. The par value reduction became effective on January 7, 2016, and accordingly, 
the CHF 3.75 billion reduction of our accumulated loss is not reflected in the accumulated loss as of December 31, 2015 
that is subject to this appropriation proposal.     

The Board of Directors proposes that the entire accumulated loss of CHF 8,682,993,000 be carried forward.

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 12, 2018. Pursuant to the proposal, the Board of Directors’ 
authority to issue new shares in one or several steps will be limited to a maximum of 22,258,043 shares, or approximately 
6% of the Company’s share capital currently recorded in the Commercial Register of the Canton of Zug. The Board of 
Directors does not currently have plans to issue shares under this authorization. 

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 capital, limited to a maximum of 22,429,838 shares, which will expire on May 16, 2016. Although the Board 
of Directors does not currently have plans to issue shares from authorized capital, it believes the proposed renewal of 
authorized share capital, which is again limited to a two-year period and to approximately 6% of the Company’s currently 
issued share capital, will help ensure that the Company will have the flexibility to make acquisitions and access equity 
capital  markets  when  opportunities  arise,  rather  than  being  subject  to  the  delays  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 new 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 Board 
of Directors the flexibility to issue additional shares out of the authorized share capital quickly could be a strategic benefit 
for the Company. 

If the proposed 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 new 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. 

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

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  new  shares  from 
authorized  capital,  the  Board  of  Directors  is  authorized  to  limit  or  withdraw  the  preemptive  rights  of  the  existing 
shareholders in various circumstances. 

In the ordinary course of our business, we may determine from time to time that the issuance of shares is in the 
best interest of the Company for various purposes, including financings, acquisitions and the issuance of shares under the 
Company’s Long-Term Incentive Plans. 

Recommendation 

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

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, Martin B. McNamara, Samuel J. Merksamer, Merrill A. “Pete” Miller, Jr., 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 eventually reflect the global 
diversity of our workforce, our customers and the cultures in which we operate, as well as who have diverse expertise in 
environmental, health, safety, industry, market and financial matters. We are a multinational company with six different 
nationalities  represented  in  our  director  and  executive  officer  group  and  over  53  in  our  global  workforce.  We  have  a 
presence in over 30 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 2016 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 a sufficient number of votes from shareholders 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 under “Investor Relations Governance.” 

The Board of Directors has received from each nominee for election at the 2016 Annual General Meeting listed 
below, an executed irrevocable letter of resignation consistent with these guidelines described above. Each such 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 18, 2016.

JEREMY D. THIGPEN, age 41, U.S. citizen, has served as President and Chief Executive Officer since April 
2015 and a director of the Company since October 2015. He previously served as Senior Vice President and Chief Financial 
Officer  at  National  Oilwell  Varco  from  December  2012  to  April  2015,  where  he  spent  18  years.  During  his  tenure  at 
National Oilwell Varco, Mr. Thigpen spent five years as the company’s President of Downhole and Pumping Solutions 
business from August 2007 until November 2012, and four years as President of its Downhole Tools group from May 
2003 to August 2007. He also served in various management and business development capacities, including director of 
Business Development and Special Assistant to the Chairman. Mr. Thigpen earned his Bachelor of Arts in Economics and 
Managerial Studies from Rice University and completed the Program for Management Development at Harvard Business 
School. 

The  Board  of  Directors  has  concluded  that  Mr. Thigpen  should  remain  on  the  Board  of  Directors  and  has 
recommended that he serve an additional term. The Board of Directors believes that it is important for the Chief Executive 
Officer of the Company to serve on the Board of Directors, as it ensures an efficient flow of information between the Board 
of Directors and executive management. In addition, Mr. Thigpen has substantial industry experience and a competitive 
perspective which assists the Board of Directors in considering strategic decisions for the Company.

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

The Audit Committee pre-approves all auditing services, review or attest engagements and permitted non-audit 
services  to  be  performed  by  our  independent  registered  public  accounting  firm.  The  Audit  Committee  has  considered 
whether the provision of services rendered in 2015 other than the audit of our financial statements and reviews of quarterly 
financial statements was compatible with maintaining the independence of Ernst & Young LLP and determined that the 
provision of such services was compatible with maintaining such independence. 

The Audit  Committee  has  adopted policies  and procedures  for  pre-approving  all  audit  and non-audit  services 
performed  by  the  independent  registered  public  accounting  firm.  The  policy  requires  advance  approval  by  the  Audit 

P-19 

 
 
 
 
 
 
    
    
    
Committee of all audit and non-audit work; provided, that the Chairman of the Audit Committee may grant pre-approvals 
of audit or non-audit work so long as such pre-approvals are presented to the full Audit Committee at its next scheduled 
meeting. Unless the specific service has been previously pre-approved with respect to the 12-month period following the 
advance approval, the Audit Committee must approve a service before the independent registered public accounting firm 
is engaged to perform the service. The Audit Committee has given advance approval for specified audit, audit-related and 
other services for 2016. Requests for services that have received this pre-approval are subject to specified fee or budget 
restrictions, as well as internal management controls.

AGENDA ITEM 10 

Advisory Vote to Approve Named Executive Officer Compensation. 

Proposal of the Board of Directors 

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  2016  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 return on capital 
employed and upon 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 a minimum equity stake 
in the Company to help 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 statements 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  2016  Annual  General  Meeting,  we  will  consider  our  shareholders’  feedback  and  the  Compensation 
Committee will evaluate whether any actions are necessary to address this feedback. 

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.

aggregate amount of compensation of the Board of Directors for the 2016/2017 Term. This amount is the maximum amount 
that  the  Company  can  pay  or  grant  to  the  members  of  the  Board  of  Directors  for  the  2016/2017  Term.  The  proposed 
aggregate maximum amount has been calculated based on the directors’ compensation elements as outlined above.

the Board. Further, the table explains our proposal for the maximum aggregate amount of compensation for our Board of 
Directors  for  the  2016/2017  Term.  The  maximum  aggregate  compensation  for  this  proposal  is  unchanged  from  the 
maximum aggregate compensation proposed for the 2015/2016 Term which was previously approved by our shareholders, 
and includes consideration for 10 non-employee directors, of whom one will be Chairman and one of whom may be Vice-
Chairman.

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 2017. 

Proposal of the Board of Directors 

The  Board  of  Directors  proposes  that  the  shareholders  ratify  an  amount  of  US$ 29,617,000  as  the  maximum 

aggregate amount of compensation of the Executive Management Team for fiscal year 2017. 

Explanation 

As  required  by  the  Minder  Ordinance  and  our  Articles  of  Association,  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 2017. 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  restricted  share  units,  club  membership  dues, 
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 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 2013-2015 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  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  and  2014,  the  shareholder 
approval levels have been 86%, 81%, 92% and 80%, 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) in fiscal year 2015, 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 
2017  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, 

P-25 

 
as reflected in the Compensation Discussion and Analysis, we anticipate that the aggregate amount actually paid to our 
Executive Management Team members for fiscal year 2017 will be less than the proposed maximum aggregate amount.  

Proposal for Ratification of Maximum Aggregate Amount 

The  Board  of  Directors  proposes  that  the  shareholders  ratify  an  amount  of  US$  29,617,000  as  the  maximum 
aggregate amount of compensation of the Executive Management Team for fiscal year 2017. This amount is the maximum 
amount that the Company can pay or grant to its members of the Executive Management Team for fiscal year 2017, 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 2016 Annual General Meeting.   

The table below shows the maximum aggregate amount of compensation that could have been paid or granted in 
the last fully completed fiscal year (fiscal year 2015) under our compensation principles and plans, the maximum aggregate 
amount of compensation available to be paid or granted for the 2016 fiscal year under our compensation principles and 
plans currently in effect, and our proposed maximum aggregate amount of compensation for fiscal year 2017. 

The  proposed  maximum  aggregate  amount  of  compensation  for  fiscal  year  2017  is  based  on  our  estimated 
compensation levels and is unchanged from the maximum aggregate amount of compensation for 2016 fiscal year which 
was approved by shareholders at last year’s Annual General Meeting.

(1)  Assuming that the base salary, the annual performance bonus and the 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 compensation, the fair value calculations are based on an assumed achievement 
of performance targets at 100%; see note 5 below for further information. 

(2)  Reflects actual base salaries paid to our Executive Management Team. 

(3)  Reflects  actual  base  salaries  paid  to,  and  base  salaries  for  the  remaining  fiscal  year  to  be  paid  to,  our  Executive 

Management Team, based on base salary levels effective for fiscal year 2016. 

(4)  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 120% of the base salary, 
depending on the level of responsibility. 

(5)  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%. The actual number of shares to be allocated under such long-term incentive units will be determined in 2020 
depending on performance achievement over a three-year performance cycle and may range between 0-200%.

(6)  Assumes that all compensation has been paid or granted at the maximum level as provided under our compensation 
principles and plans. Social security payments to be paid by the Company pursuant to applicable law are not included 
in the total amount. 

(7)  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 for 
each fiscal year are included for illustration purposes only. 

We anticipate that the aggregate amount actually paid to our Executive Management Team for fiscal year 2017 
will be less than the proposed maximum aggregate amount. Actual compensation paid to our Executive Management Team 
for fiscal year 2015 was US$ 18,242,593 (on the basis of the grant-date fair values of the long-term incentive grants for 
fiscal  year  2015),  compared  to  a  maximum  amount  payable  under  our  compensation  plans  and  principles  of 
US$ 28,367,000. Notwithstanding that we anticipate that the aggregate amount actually paid to our Executive Management 
Team for fiscal year 2017 will be less than the proposed maximum aggregate amount, we request our shareholders approve 
the proposed maximum aggregate amount. This is because we want 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 the maximum performance level. 

The actual payout and grants will be disclosed in the proxy statement for our 2018 annual general meeting and 

the Swiss Compensation Report for fiscal year 2017.

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

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. 

In February 2011, the Board of Directors adopted a Code of Integrity that updated and replaced our previous Code 
of Business Conduct and Ethics. We regularly review and, as necessary, update our 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 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  under  “Investor 

Relations—Governance.” Among the information you can find there is the following: 

•  Articles of Association; 

•  Organizational Regulations; 

•  Corporate Governance Guidelines; 

•  Audit Committee Charter; 

•  Corporate Governance Committee Charter; 

•  Compensation Committee Charter; 

•  Finance Committee Charter; 

•  Health Safety and Environment Committee Charter; 

•  Our Mission Statement; 

•  Our FIRST Shared Values; and 

P-28 

•  Code of Integrity. 

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. 
However, following Mr. Newman’s resignation as Chief Executive Officer of the Company and resignation from the Board 
of Directors in February 2015, Ian C. Strachan served in a dual capacity as Chairman of the Board of Directors and Interim 
Chief  Executive  Officer  until  the  Company  named  Jeremy  D.  Thigpen  as  President  and  Chief  Executive  Officer.  The 
Company intends to continue its practice of separating the positions of Chief Executive Officer and Chairman of the Board 
for the reasons identified above. 

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 their oversight role and their 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 undertaken an extensive review and improvement of its Enterprise Risk Management (“ERM”) 
process and has implemented an ERM 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 meets regularly and 
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  2015,  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.   

P-29 

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 all of its current members, with the exception of Jeremy D. Thigpen 
(our President and Chief Executive Officer), are independent and meet the applicable independence standards set by the 
NYSE, the SEC and our guidelines. Accordingly, our Compensation, Audit and Corporate Governance Committees are 
composed solely of directors who meet the NYSE and SEC independence standards.   

In  making  its  independence  determinations,  the  Board  of  Directors  considered  the  fact  that,  while  such 
relationships do not preclude independence under the NYSE and SEC rules or the Company’s guidelines, Glyn A. Barker, 
Chadwick C. Deaton, Vincent J. Intrieri, Samuel J. Merksamer, Merrill A. “Pete” Miller, Jr. and Tan Ek Kia are, or within 
the past three years have been, directors or officers of companies with which we conduct business in the ordinary course. 
In addition, Edward R. Muller’s son has been working as an associate attorney at Munger, Tolles & Olson LLP, a law firm 
that provides legal services to the Company.   

Since 2012, Mr. Barker has served as a non-executive director of Aviva plc, a company that provides insurance 
related services to the Company. Additionally, since July 2014, Mr. Barker has served as a director and member (and until 
July 2015 as chairman) of the audit committee, and since July 2015, as chairman of the board of directors of, Transocean 
Partners LLC, a publicly-held subsidiary of Transocean Ltd. to which we provide operating, support and administrative 
services, in addition to being the majority unitholder.   

In 2013, Mr. Deaton resigned from his position as executive chairman of Baker Hughes Incorporated, from which 
the Company purchases drilling equipment and services. 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. 
Further,  since  2014,  Mr. Deaton  has  served  as  a  non-executive  director  of  Marathon  Oil  Corporation,  from  which  we 
receive revenues for performing services.   

In addition to his affiliation with Carl Icahn and certain investment funds managed by Mr. Icahn, from 2013 to 
2015,  Mr. Merksamer  served  as  a  non-executive  director  of  Talisman  Energy,  from  which  we  received  revenues  for 
performing services, and, beginning in 2014, Mr. Merksamer has served as a director of Hertz Global Holdings, Inc., from 
subsidiaries of which the Company procures car rental services. In February 2016, American International Group, Inc. 
announced that Mr. Merksamer will be nominated as non-executive director of American International Group, Inc. for 
election  at  its  2016  annual  meeting  of  shareholders.  American  International  Group,  Inc.  is  a  company  that  provides 
insurance-related  services  to  the  Company.  As  with  Mr. Barker,  Mr. Merksamer  joined  the  board  of  directors  of 
Transocean Partners LLC in 2014.   

In addition to his affiliation with Carl Icahn and certain investment funds managed by Mr. Icahn, since 2014, Mr. 

Intrieri has served as a director of Hertz Global Holdings, Inc.   

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.   

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. Mr. Miller currently serves as the executive 
chairman of NOW Inc. from which the Company regularly purchases drilling equipment and services.   

The Board of Directors believes that all of these transactions were on arm’s-length terms that were reasonable 
and competitive. Accordingly, the Board of Directors concluded that these relationships 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. 

P-30 

Executive  Sessions.  Our  independent  directors  met  in  executive  session  without  management  at  each  of  the 
regularly scheduled Board of Directors meetings held in 2015. During 2016, they 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 NYSE independence requirements. 

Our Corporate Governance Guidelines provide that  the Corporate Governance Committee should periodically 
assess the needs of our 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 and whether or not the candidate can contribute positively to the existing chemistry and collaborative 
culture among the Board members. Also, the Corporate Governance Committee 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 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. An uncontested election occurs in an election of directors that does 
not constitute a contested election. A contested election for purposes of the Corporate Governance Guidelines occurs when 
(i) the Secretary of the Company receives a notice that a shareholder has nominated a person for election to the Board of 
Directors in compliance with the advance notice requirements for shareholder nominees for director set forth in our Articles 
of Association and (ii) such nomination has not been withdrawn by such shareholder on or prior to the day next preceding 
the date the Company first mails its notice of meeting for such meeting to the shareholders. 

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

P-31 

The  Corporate  Governance  Committee  considers  nominees  for  director  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-6300 
Zug, 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—Proposals of Shareholders.” 

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.” 

P-32 

Director  compensation  is  set  by  the  Board  of  Directors  upon  a  recommendation  from  the  Compensation 
Committee. Since 2015, director compensation is also subject to shareholder approval at the Company’s annual general 
meetings. Each calendar year, the Compensation Committee reviews the compensation paid to our directors to be certain 
that it is competitive in attracting and retaining qualified directors. The Compensation Committee has used its outside 
consultant 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-6300 Zug, 
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 which it may request 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 $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 immediately must inform the Board of Directors or the Chairman 
of the Board of Directors in the event that a director believes that the director 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 certain 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 2015, there were no 
related person transactions where such policies and procedures were not followed. 

Certain  Relationships  and  Related  Party  Transactions.  From  2001  to  2014,  Mr. Miller  served  as  president & 
chief  executive  officer  of  National  Oilwell  Varco, Inc.  (NYSE:  NOV).  Mr. Miller  currently  serves  as  the  executive 
chairman of NOW Inc. (NYSE: DNOW). We regularly procure equipment and services from National Oilwell Varco, Inc. 
and its affiliates (together “NOV”) and NOW Inc., each at arm’s length terms and within the ordinary course of business. 
In 2015, our purchasing activity with NOV and NOW Inc. represented less than 2% of each company’s reported gross 
revenues for such periods. 

P-33 

Director Attendance at Annual General Meeting. We expect all of our directors to attend the 2016 Annual General 
Meeting. At the 2015 Annual General Meeting, all directors then serving on the Board of Directors were in attendance.   

Board Meetings and Committees 

During 2015, the Board of Directors of Transocean Ltd. held seven 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 under “Investor Relations—Governance.” 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, (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 Executive 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 relevant period; 

annually review and approve the compensation paid to members of the Board of Directors and Specified 
Executives; 

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;

evaluation together with competitive data and subject to shareholder ratification requirements pursuant to our 
Articles of Association and applicable law;

Compensation Plan, and any other compensation plans or arrangements providing for benefits primarily to 
members of the Board of Directors and executive officers in accordance with goals and objectives established 
by the Board of Directors, the terms of the plans, and any applicable rules and regulations; 

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

consider, with guidance from an outside compensation consultant, and approve the material terms of any 
employment, severance, termination or other similar arrangements (to the extent permitted by applicable law 

P-34 

and  our  Articles  of  Association)  that  may  be  entered  into  with  members  of  the  Board  of  Directors  and 
Specified Executives; provided, however, that the Compensation Committee shall not recommend and the 
Board of Directors shall not authorize “single-trigger” change of control agreements for any of our officers 
or directors; 

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

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

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

Committee. 

The  Compensation  Committee  may  delegate  specific  responsibilities  to  one  or  more  individual  committee 
members to the extent permitted by law, NYSE listing standards and the Compensation Committee’s governing documents. 
The  Compensation  Committee  may  delegate  all  or  a  portion  of  its  powers  and  responsibilities  with  respect  to  the 
compensation plans and programs described above and in our “Compensation Discussion and Analysis” to one or more of 
our management committees; provided, that the Compensation Committee retains all power and responsibility with respect 
to awards granted to our Board members and executive officers. The Chief Executive Officer has been delegated authority 
to grant equity awards under the Company’s Long-Term Incentive Plans to new and existing employees of the Company, 
excluding executive officers and other officers above the Vice President level, provided that such awards shall not exceed 
$5,000,000 in grant value per calendar year in aggregate and no such individual award shall exceed $350,000 in grant 
value.   

The  Compensation  Committee  has  delegated  to  a  subcommittee  composed  of  its  chairman  and  at  least  one 
additional  committee  member  the  authority  to  approve  interim  compensation  actions  resulting  from  promotions, 
competitive realignment, or the hiring of new executive officers (excluding the Chief Executive Officer), including but not 
limited to establishing annual base salary, annual bonus targets, long-term bonus targets and the grant of equity awards, 
subject to any required vote of the shareholders. The Compensation Committee has also delegated authority to the Chief 
Executive Officer to, upon termination of service of an employee of the Company (excluding executive officers and other 
officers at or above the Senior Vice President level), accelerate vesting of awards granted under the Company’s Long-Term 
Incentive Plan 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 Incentive Plan. 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, Intrieri and 

McNamara. The Compensation Committee met seven times during 2015.   

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

The current members of the Finance Committee are Mr. Muller, Chairman, Ms. Chang and Messrs. Barker and 

Merksamer. The Finance Committee met four times during 2015.   

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 

P-35 

Directors functions and how the Board of Directors should interact with shareholders and management. It reviews the 
qualifications of potential candidates for the Board of Directors, coordinates the self-evaluation of the Board of Directors 
and committees 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. McNamara,  Chairman,  and 

Messrs. Deaton and Intrieri. The Corporate Governance Committee met five times during 2015.   

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. Beginning in 2013, 
the  Health  Safety  and  Environment  Committee  assumed  additional  responsibility  to  oversee  the  Company’s 
implementation of certain requirements of the Consent Decree by and among the U.S. Department of Justice and certain 
of the Company’s affiliates. The Health Safety and Environment Committee has required the Company to provide, and 
will review, 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. The Health Safety and Environment Committee met four times during 2015.   

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

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

• 

• 

• 

• 

• 

an understanding of generally accepted accounting principles and financial statements; 

the ability to assess the general application of such principles in connection with the accounting for estimates, 
accruals, and reserves; 

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

an understanding of internal control over financial reporting; and 

an understanding of audit committee functions. 

P-36 

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

• 

• 

• 

• 

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

experience actively supervising a principal financial officer, principal accounting officer, controller, public 
accountant, auditor or person performing similar functions; 

experience overseeing or assessing the performance of companies or public accountants with respect to the 
preparation, auditing or evaluation of financial statements; or 

other relevant experience. 

The current members of the Audit Committee are Mr. Barker, Chairman, Ms. Chang and Mr. Curado. The Audit 

Committee met eight times during 2015.     

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 has served 
as President and Chief Executive Officer of Embraer S.A. since 2007 and has significant risk management and compliance 
experience.   

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  that  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 Board of Directors service. 

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. 

P-37 

In 2015, non-employee director compensation included the following fixed components:   

Annual Retainer—non-employee Director

(1)  Mr. Miller served as non-employee Vice Chairman until May 15, 2015. Currently, the Company does not have any 

director serving in a Vice Chairman role. 

(2) 

In May 2015, the annual retainer for the non-employee Chairman was increased from $265,000 to $325,000 for the 
compensation period from the Company’s 2015 Annual General Meeting to the Company’s 2016 Annual General 
Meeting (“2015/2016 Compensation Period”). 

(3)  Restricted  share  units  are  granted  to  each  non-employee  director  annually  and  have  an  aggregate  value  equal  to 
$210,000,  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. 

(4) 

In May 2015, the aggregate value of units granted to the non-employee Chairman was increased from $260,000 to 
$325,000 for the 2015/2016 Compensation Period. 

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. 

2015 Director Compensation 

In 2015, each non-employee member of the Board of Directors received the compensation described above. 

At the Board of Directors meeting held immediately after the 2015 Annual General Meeting of our shareholders, 
the Board of Directors granted 10,836 restricted share units to each non-employee director (other than the Chairman) and 
16,770  restricted  share  units  to  the  non-employee  Chairman  in  aggregate  value  equal  to  $210,000  and  $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 $19.38 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 

Two primary roles of the Audit Committee are to (1) assist the Board of Directors in overseeing the key financial 
and compliance related matters and (2) monitor integrity of the financial statements of the Company. While management 
is responsible for the Company’s internal controls and the financial reporting process, in accordance with its Charter, the 
Audit Committee encourages continuous improvement of and fosters adherence to the Company’s policies, procedures 
and practices at all levels. 

The Audit Committee is also directly responsible for the appointment, compensation, retention and oversight of 
the  independent  registered  public  accounting  firm,  Ernst &  Young LLP,  and  our  auditor  under  the  Swiss  Code  of 
Obligations. Ernst & Young LLP has been the Company’s independent registered public accounting firm since 1993 and 
is responsible for performing an independent audit of the Company’s financial statements in accordance with the standards 
of  the  PCAOB.  The Audit  Committee  considers  the  effectiveness  of  these  processes  and  the  independence of  Ernst & 
Young LLP on an on-going basis. A full description of the Audit Committee’s key functions is contained in the Company’s 
Audit Committee Charter available at: www.deepwater.com/investor-relations/governance/committees/audit-committee. 

As part of its oversight function for the year ended December 31, 2015, the Audit Committee: 
•  Reviewed and discussed the audited financial statements of the Company to be included in the Annual Report 

with management, our internal auditors and Ernst & Young LLP; 

•  Discussed  with  Ernst &  Young LLP  the  matters  required  to  be  discussed  by  the  Statement  on  Auditing 
Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the 
Public Company Accounting Oversight Board in Rule 3200T; 

• 

In accordance with the Sarbanes-Oxley Act of 2002, which requires certifications by the Company’s chief 
executive officer and chief financial officer in certain of the Company’s filings with the SEC, discussed the 
review of the Company’s reporting and internal controls undertaken in connection with these certifications 
with the Company’s management and independent registered public accounting firm; 

•  Reviewed and discussed with the Company’s management and independent registered public accounting firm 
management’s  report  and  Ernst &  Young LLP’s  report  on  internal  control  over  financial  reporting  in 
accordance with Section 404 of the Sarbanes-Oxley Act of 2002; 

•  Developed quarterly meeting agendas based on input from each Committee member, Ernst & Young LLP, 

members of management and the Company’s internal audit function; 

•  Conducted  regular  meetings  with  our  internal  auditors  and  Ernst &  Young LLP  (with  and  without 
management  present)  to  discuss  the  overall  scope  and  plans  for  future  audits,  results  of  examinations, 
evaluations of internal controls and other material matters; 

•  Reviewed all non-audit services and engagements, service quality and working relationships with Ernst & 

Young LLP; and 

•  Reviewed such other matters as it deemed appropriate, including other provisions of the Sarbanes-Oxley Act 

of 2002 and rules adopted or proposed to be adopted by the SEC and the NYSE. 

The Audit Committee also has received the written disclosures and the letter from Ernst & Young LLP regarding 
the auditor’s independence pursuant to the applicable requirements of the Public Company Accounting Oversight Board 
Ethics and Independence Rule 3526, and it has reviewed, evaluated and discussed the written disclosures with that firm 
and its independence from the Company. The Audit Committee further has discussed with management of the Company 
and the independent registered public accounting firm such other matters and received such assurances from them as it 
deemed appropriate. 

P-40 

 
 
Based on the foregoing review and discussions and relying thereon, the Audit Committee recommended to the 
Company’s  Board  of  Directors  the  inclusion  of  the  Company’s  audited  financial  statements  for  the  year  ended 
December 31, 2015, in the Company’s Annual Report on Form 10-K for such year filed with the SEC.

comprise our Named Executive Officers for 2015: 

Current Executive Officers 

• 
Jeremy D. Thigpen, President and Chief Executive Officer 
•  Mark Mey, Executive Vice President and Chief Financial Officer 
• 
•  David Tonnel, Senior Vice President, Supply Chain and Controller 
•  Terry Bonno, Senior Vice President, Marketing

Directors under Swiss law and the Company’s organizational documents with respect to Messrs. Thigpen, Mey, Stobart, 
Newman, Strachan and Ikaheimonen. 

We experienced significant changes to our leadership team in 2015 as our Board of Directors acted to position 
the Company for future success. Specifically, on February 16, 2015, Steven Newman, in mutual agreement with the Board 
of Directors, stepped down as President and Chief Executive Officer and resigned as a Director of Transocean Ltd. Ian 

P-44 

 
 
Strachan, Chairman of the Board of Transocean Ltd., immediately assumed the role of Interim Chief Executive Officer, 
pending  a  full-time  appointment  of  the  role  vacated  by  Mr.  Newman.  Separately,  Esa  Ikaheimonen  stepped  down  as 
Executive  Vice  President  and  Chief  Financial  Officer  on  May  27,  2015.  In  addition,  Lars  Sjobring  resigned  as  the 
Company’s Senior Vice President and General Counsel on November 9, 2015. 

Our  President  and  Chief  Executive  Officer,  Mr.  Thigpen,  was  hired  on  April  22,  2015.  Mr.  Thigpen  was 
subsequently elected to the Transocean Ltd. Board of Directors at an Extraordinary General Meeting held on October 29, 
2015. Mark Mey was hired on May 28, 2015, as Executive Vice President and Chief Financial Officer. Messrs. Thigpen 
and Mey bring deep industry experience to our executive team. Brady Long was hired on November 10, 2015, as Senior 
Vice  President  and  General  Counsel,  bringing  additional  industry  experience  to  the  executive  team.  These  executives, 
together  with  the  rest  of  the  executive  leadership  team,  are  well-positioned  to  lead  the  Company  to  emerge  from  the 
industry downturn as the undisputed leader in offshore drilling.   

Executive Summary 

Our executive compensation program reflects our commitment to best practices in compensation governance and 
strongly aligning pay with Company performance while allowing us to attract and retain highly qualified executives. The 
program is designed to motivate our executives to achieve important business objectives and to reward them for creating 
long-term value for our shareholders by delivering superior financial, safety and operational performance. 

We believe our executive compensation program includes features that effectively align the interests of our senior 
management with those of our shareholders and excludes features that may result in misalignment. Important features of 
our executive compensation programs and practices are provided in the following table:

2015 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. With a particular focus on 
deepwater and harsh-environment drilling services, Transocean believes that it operates one of the most versatile offshore 

P-45 

 
 
 
drilling fleets in the world. 

Over the last year and a half, oil prices have fallen to levels not seen in more than a decade, driven primarily by 
global concerns around supply and demand imbalances. As a result, our customers continue to significantly curtail both 
their  exploration  and development  activities,  resulting  in a limited  number  of near-term  offshore  drilling  prospects.  In 
response, we are taking the necessary steps to maintain our market leadership position through this downturn, and position 
ourselves to emerge even stronger and leaner when the recovery occurs. 

As illustrated in the chart below, the equity market valuations of offshore drillers reflect these adverse market 

conditions.

Offshore Drillers include: RIG, ATW, DO, ESV, NE, ORIG, PACD, RDC and SDRL 

As of February 11, 2016, Transocean owns, or has partial ownership interests in, and operates a fleet of 61 mobile 
offshore  drilling  units  consisting  of  28  ultra-deepwater  floaters,  seven  harsh-environment  semisubmersibles,  five 
deepwater semisubmersibles, 11 midwater semisubmersibles, and 10 high-specification jackups. In addition, the Company 
has  six  ultra-deepwater  drillships  and  five  high-specification  jackups  under  construction  or  under  contract  to  be 
constructed. 

In  2015,  Transocean  continued  to  be  proactive  in  areas  that  are  critical  to  the  Company’s  success  including: 
maintaining an intense focus on fleet utilization; increasing our financial flexibility; eliminating unnecessary costs from 
the business; and efficiently operating and renewing our fleet.   

Our focus on maximizing the utilization of our fleet resulted in the addition of contract backlog during 2015 of 
approximately  $763  million,  contributing  to  an  overall  contract  backlog  of  approximately  $16 billion  at  December 31, 
2015.  In  the  context  of  a  highly  competitive  and  challenging  market,  our  industry  leading  backlog  provides  a  visible 
foundation for future cash flow generation and enhances the Company’s financial flexibility. 

With over $2 billion of cash as we enter 2016, and an undrawn, unsecured revolving credit facility of $3 billion, 
we have sufficient liquidity to fulfill our existing commitments, with optionality to evaluate and potentially pursue value-
enhancing transactions, which could materialize in the current market. Also, reflecting our financial flexibility, in 2015 we 
opportunistically repurchased $503 million of debt at a total cost of $473 million. 

We continue to define and implement innovative plans to remove cost from our business, while improving our 
operating performance. In 2015, we outperformed our internal targets and expectations for critical operating metrics, while 
meaningfully reducing our cost structure. As we have rationalized our fleet, and re-focused our operations on the deepwater 
markets  and  other  areas  that  require  high-specification  assets  and  capabilities,  we  have  right-sized  our  support,  and 
streamlined our processes, removing considerable shore-based costs. We also continue to realize opportunities to more 

P-46 

 
 
 
 
 
 
 
efficiently maintain our equipment, manage shipyard projects, stack uncontracted assets and recycle less marketable assets.   

Reflecting the success of our operational strategy, our revenue efficiency for 2015 was 96.0%, up from 94.7% in 
2014.  Our  ability  to  continue  to  perform  to  these  elevated  expectations  ultimately  enhances  our  market  position  and 
shareholder value. 

We continue to high-grade our fleet. We have recently added two new ultra-deepwater drillships, the Deepwater 
Thalassa and the Deepwater Proteus, to our fleet of world class assets. Both of these rigs have firm 10-year contracts with 
Shell. Additionally, we will add a third ultra-deepwater drillship, the Deepwater Conqueror, to our fleet later in the year 
that  will  commence  a  five-year  contract  with  Chevron.  In  2015  our  high-grading  also  included  identifying  10  lower-
specification floaters for recycling, with an additional two floaters classified as held for sale, bringing our total retired or 
held for sale floaters since the start of the downturn to 24 as of February 11, 2016. 

In 2015, we continued to drive year-over-year improvements in our safety performance. We remain committed 
to our vision of “an incident-free workplace all the time, everywhere” and will continue to make investments to promote 
safety.   

Given our 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. 

Relationship Between Target and Realizable Pay 

Consistent with our philosophy of aligning the interests of our Executive Officers with those of our shareholders 
by basing the majority of compensation on achieving desired performance outcomes, the actual total compensation values 
received by  our  Executive Officers,  in recent  years, have  fallen  below  targeted  and  competitive  market  levels.  This  is 
primarily a result of the lack of appreciation in the Company’s share price and below-target total shareholder return relative 
to our peers. 

In contrast to the information reported in the Summary Compensation Table, which reflects the grant-date fair 
value for share awards, we believe that realizable pay provides a better picture of the amounts actually earned. In particular, 
we note that there have been no payouts under our performance-based unit program over the last six performance cycles, 
and all outstanding stock options are currently underwater.

2015 Compensation Program Overview   

The Company reinforced the alignment between pay and performance with our executive compensation programs 

and compensation award levels for 2015. 

In recognition of the current global industry downturn, the Compensation Committee gave prudent consideration 
in  developing  target  2015  compensation  opportunities  for  our  Named  Executive  Officers.  Working  closely  with  our 
independent compensation consultant, the following executive compensation actions were implemented for our Named 
Executive Officers: 

•  No payout for the 2013-2015 performance unit cycle; 
•  Freeze of base salaries for all Executive Officers for 2015 and 2016; 
•  Freeze of target annual incentive opportunities for all of our Executive Officers for 2015 and 2016; 
•  Reduction in target 2015 Long-Term Incentive awards by approximately 20%; 
•  Freeze of long-term incentive award targets for 2016 at the reduced targets for 2015; and 
•  Freeze of defined benefit pension plan and non-qualified Pension Equalization Plan to future benefit accruals, 

effective January 1, 2015. 

These compensation actions reflect the reality of our current market, while maintaining competitive compensation 

packages for our Named Executive Officers. 

Executive Compensation Philosophy, Strategy and Design 

The objective of our compensation program is to align pay with performance.  The program is designed to attract, 
motivate and retain superior executive talent in the geographic locations necessary to support our global operations.  The 

P-48 

 
 
 
 
 
 
program is also designed to provide our executives with a competitive compensation package that rewards performance 
against  specific identified financial, strategic and operational goals that the Compensation Committee believes are critical 
to the  Company’s long-term success and the achievement of sustainable long-term total returns to our shareholders. 

positioning each element of total direct compensation at approximately the median of our peer companies; 

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

aligning annual incentive compensation with financial and strategic objectives; and 

rewarding absolute financial performance and relative performance in total shareholder return (“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 
shareholder  value  without excessive risk-taking.  We  believe  the  approach  achieves  our  objective  of  aligning  pay  and 
performance.

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 Compensation 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: 

• 

• 

externally against the 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 enhancing shareholder value and achieving our vision and business strategy. 

The Compensation 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 performance of the Company.

Compensation Peer Group 

We compete for executive talent across many different sectors around the world. 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. 

The Compensation Peer Group for 2015 comprised the following companies: 

(cid:404)  Anadarko Petroleum Corporation 
(cid:404)  Apache Corporation 
(cid:404)  Baker Hughes Incorporated 
(cid:404)  BG Group plc 
(cid:404)  Cameron International Corporation 
(cid:404)  Canadian Natural Resources Limited 
(cid:404)  Chesapeake Energy Corporation 
(cid:404)  Devon Energy Corporation 

(cid:404)  Diamond Offshore Drilling, Inc. 
(cid:404)  Encana Corporation 
(cid:404)  Ensco plc 
(cid:404)  EOG Resources, Inc. 
(cid:404)  FMC Technologies, Inc. 
(cid:404)  Halliburton Company 
(cid:404)  Marathon Oil Corporation 
(cid:404)  Nabors Industries Ltd. 

(cid:404) National Oilwell Varco, Inc. 
(cid:404)  Noble Corporation plc 
(cid:404) Noble Energy, Inc. 
(cid:404) Petrofac Limited 
(cid:404)  Seadrill Limited 
(cid:404) Talisman Energy Inc. 
(cid:404) Weatherford International Ltd. 

In addition, we consider the compensation practices of non-energy general industry peers of comparable size and 
international scope in setting executive compensation levels and use general industry data as a secondary market reference. 
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 operations roles, whereas general industry data 
are  weighted  more  heavily  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  Compensation  Committee  established  the  Performance  Peer  Group  in  order  to  evaluate  the  Company’s 
total  shareholder return relative to that of companies considered to be direct business competitors and competitors for 
investment capital.  The Performance Peer Group consists of: 

(cid:404)  Baker Hughes Incorporated   
(cid:404)  Diamond Offshore Drilling, Inc. 
(cid:404)  Ensco plc 
(cid:404)  Halliburton Company 
(cid:404)  Nabors Industries Ltd. 
(cid:404)  National Oilwell Varco, Inc. 

(cid:404) Noble Corporation plc 
(cid:404)  Rowan Companies Inc. 
(cid:404) Schlumberger Limited 
(cid:404) Seadrill Limited 
(cid:404)  Weatherford International Ltd.

Executive Compensation Components 

Our executive compensation program is designed to meet the objectives of our “pay for performance” philosophy 

by linking a significant portion of each executive’s compensation to Company and individual performance. 

The following table summarizes the purpose and key characteristics of each of the primary components of our 

executive compensation  program.

Purpose 
Provide a base level of income, targeting 
the market median for executive talent. 
Individual circumstances may result in 
certain positions above or below market 
median. 
Motivate executives to achieve our 
short-term business objectives and 
reward contributions toward the 
achievement of pre-established 
performance goals. 

Align the interests of our executives 
with those of our shareholders by 
creating a direct correlation of realized 
pay to key value drivers and increased 
shareholder return relative to 
performance peers over the long term. 

Motivate executives to contribute to 
long-term increases in shareholder 
value, build executive ownership and 
retain executives through multi-year 
vesting. 

Assist expatriate executives with part of 
the additional burden of an overseas 
posting. 

Provide benefits that promote employee 
health and welfare and assist executives 
in carrying out their duties and 
increasing productivity. 

Retain executives by providing a 
measure of financial security in the 
event an executive’s employment is 
terminated without cause. 

Key Characteristics 

Fixed compensation. Reviewed annually 
and adjusted as appropriate. 

Variable compensation. Based on 
corporate performance compared to pre-
established performance goals. Award 
potential ranges from 0% to 200% of 
target. 
Variable compensation. The number of 
earned units is based on both relative 
measures (e.g., total shareholder return 
relative to performance peers during 
three-year performance periods) and 
absolute performance measures (Return 
on Capital Employed). 

Variable compensation. Long-term award 
with ratable vesting over three years that 
provides a direct correlation of realized 
pay to shareholder value. 

Fixed compensation. Provided to 
expatriate executives to assist with living 
expenses (e.g., housing, dependent 
education, cost of living differentials and 
automobile allowances). 

Indirect compensation elements 
consisting of health and welfare plans 
and minimal perquisites. 

Fixed compensation. Severance benefits, 
to the extent permissible under Swiss 
law, are provided pursuant to the 
Executive Severance Policy and are not 
payable in the event of a termination for 
cause or a voluntary resignation without 
good reason. 

In addition, our Named Executive Officers have historically received stock options that provide a direct link to 

long-term stock price appreciation. 

In assessing the reasonableness of the total direct compensation of the Named Executive Officers, particularly the 
compensation  of  our  Chief  Executive  Officer,  the  Compensation  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  Compensation 
Committee  upon  each  officer’s  initial  hire  and  reviewed  in  connection  with  a  promotion  or  other  change  in  job 
responsibility. Each base salary is also reviewed by the Compensation 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 Compensation Committee considers input from our Chief Executive Officer, 
competitive compensation from our Peer Group and other survey data, job responsibilities, individual performance, and 
expected future contributions of each Named Executive Officer. The Compensation Committee also considers input from 
its compensation consultant as well as the Company’s compensation philosophy and objectives. 

In  February  2015,  the  Compensation  Committee,  in  consideration  of  the  current  market  downturn,  and  with 
consultation  from  its  external  compensation  consultant,  elected  to  freeze  base  salaries  for  Named  Executive  Officers, 
resulting  in  no  2015  increases  over  the  2014  base  salaries  noted  above.  In  addition,  base  salaries  were  also  frozen  in 
February 2016 with respect to 2016 base salaries. 

The following base salaries (or US$ base salary reference) were approved by the Committee for the individuals listed 

below.

(1) Messrs. Thigpen and Mey’s 2015 base salaries became effective on their hire dates of April 22 and May 28, respectively.   

Due to interim nature of Mr. Strachan’s role, the Board of Directors approved Mr. Strachan’s compensation as a 
monthly  rate.  For  the  total  compensation  details  for  Mr.  Strachan,  see  “Executive  Compensation—Summary 
Compensation Table.”   

Annual Performance Bonus 

Our Performance Award and Cash Bonus Plan (the “Bonus Plan”) is a goal-driven plan that provides participants, 
including the Named Executive Officers, 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 Compensation 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, on average, to earn total 
cash compensation approximating competitive market median levels. Performance above and below the target provides 
the  opportunity  for  participants  to  earn  total  annual  cash  compensation  above  the  competitive  market  median,  when 
warranted,  by  above-target  performance,  up  to  a  designated  maximum;  or,  the  possibility  of  earning  total  annual  cash 
compensation below the median for below-target performance. 

Under the Bonus Plan for 2015, each Named Executive Officer had a potential payout range of 0% to 200% of 
his individual target award opportunity. The Compensation Committee established a 2015 target bonus opportunity for

Due to the interim nature of Mr. Strachan’s role, no bonus opportunity was established for 2015. 

2015 Bonus Payout 

The Compensation Committee considered the results of key performance areas, specified at the beginning of 2015, 
when determining the outcomes of the variable, performance-based compensation under the Performance Award and Cash 
Bonus  Plan for our Named Executive Officers for 2015.     

Each of the following performance areas is measured with potential payouts ranging from 0% to 200%. 

•  Safety Performance – 30% weighting 
−  Total Recordable Incident Rate   
−  Total Potential Severity Rate   
−  Process Safety   

•  Cash Flow Value Added – 30% weighting 
•  Revenue Efficiency – 20% weighting   
•  Operating Costs – 20% weighting     

Each of these measures is discussed in greater detail below. 

Safety Performance 

Our business involves numerous operating hazards, and we are strongly committed to protecting our employees, 
our property and the environment. Our ultimate goal is expressed in our safety vision of “an incident-free workplace-all 
the time, everywhere.” The safety performance targets for 2015 were approved by the Compensation Committee and levels 
are set annually to motivate our executives to achieve continuous improvement in safety performance and to meet strict 
internal standards. Safety performance targets are recommended to the Compensation Committee by the Board’s Health 
Safety and Environment Committee. 

The Compensation Committee measures our safety performance through a combination of components: Total 
Recordable Incident Rate (“TRIR”), Total Potential Severity Rate (“TPSR”) and Process Safety. Each component makes 
up one-third of the overall safety performance metric. 

P-53 

 
 
 
 
 
 
The following charts show our actual performance related to the formulaic payout amounts for TRIR, TPSR and 

Process Safety. 

Together, the safety metric outcomes resulted in a formulaic payout percentage for this measure of 48% of the 

total target bonus opportunity for each of the Named Executive Officers in 2015. 

Total Recordable Incident Rate   

TRIR is a safety performance metric recognized by the U.S. Occupational Safety & Health Administration and is 
used by companies across an array of different industries. We calculate TRIR based upon the guidelines set forth by the 
International Association of Drilling Contractors (the “IADC”), an industry group for the drilling industry. 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 the injury or illness; an employee not being able to perform all of his or her 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 Compensation Committee approved a TRIR target for 2015 of 0.51, which would represent further progress 

toward our safety vision. Values above and below this target were calculated in accordance with the chart below, with 
outcomes falling in between two boundaries interpolated on a straight-line basis: 

TRIR Outcome to Target 
20% Improvement Exceeding Target 
10% Improvement Exceeding Target 
Target 
10% Shortfall 
20% Shortfall 

Bonus Payout 
200% 
150% 
100% 
50% 
0% 

Any TRIR outcome representing a shortfall of more than 20% as compared to the target would result in a 0% 
bonus payout for the TRIR metric and any outcome representing an improvement of 20% or greater as compared to the 
target  would  result  in  a  payout  of  200%  for  the  TRIR  metric.  Our  TRIR  outcome  for  2015  was  0.42,  representing  an 
improvement of just over 20% as compared to target and represents the best TRIR result in the Company’s history. This 
resulted in a formulaic result of 200% of target for the TRIR metric and a formulaic result for this measure of 20% of the 
total target bonus opportunity for each of the Named Executive Officers. 

Total Potential Severity Rate   

TPSR is an internally developed safety measure that we utilize to capture the potential severity of incidents over 
a period of time. TPSR is calculated by taking the sum of all potential severity values assigned to the incidents, multiplying 
that number by 200,000, then dividing that number by total employee hours worked. After the occurrence of an incident, 
the manager(s) responsible for the drilling unit or onshore facility where the incident occurred completes an incident report 

P-54 

 
 
 
 
 
 
 
 
 
that  assigns  a  preliminary  severity  value  to  the  incident.  The  Company  also  has  an  independent  oversight  and  review 
process to evaluate and confirm the potential severity assigned to each incident. The severity value is derived by inputting 
data into our comprehensive severity calculator. For instance, for dropped objects, the height from which the item was 
dropped and the weight of the object are inputs into the severity calculator. 

The Compensation Committee approved a TPSR target for 2015 of 16.3, which represents further progress toward 
our safety vision. Values above and below this target were calculated in accordance with the chart below, with outcomes 
falling in between two boundaries interpolated on a straight-line basis: 

TPSR Outcome to Target 
20% Improvement Exceeding Target 
10% Improvement Exceeding Target 
Target 
10% Shortfall 
20% Shortfall 

Bonus Payout 
200% 
150% 
100% 
50% 
0% 

Any TPSR outcome representing a shortfall of more than 20% as compared to the target would result in a 0% 
bonus payout for the TPSR metric, and any outcome representing an improvement of 20% or greater as compared to the 
target  would  result  in  a  payout  of  200%  for  the  TPSR  metric.  Our  TPSR  outcome  for  2015  of  13.98  represented  an 
improvement of just under 15% as compared to the target. This improvement resulted in a formulaic result of 171% of 
target for the TPSR metric, and a formulaic result for this measure of 17% of the total target bonus opportunity for each of 
the Named Executive Officers. 

Process Safety 

We believe that in addition to personnel and behavioral safety, prevention and mitigation of major hazards or 
process  incidents  are  critical  components  of  a  successful  safety  program.  Accordingly,  Process  Safety  is  an  internally 
developed safety measure designed to assess the management of major hazards in order to prevent or mitigate a major 
accident or significant event. 

We use industry standard definitions of significant events, which include: 

•  Fire, explosion, release of a hazardous substance with serious injury or fatality 
•  Major structural damage 
•  Serious injuries/fatalities 
•  Uncontrolled release of hazardous fluids 

To implement this safety measure, we measure the number of process safety events that are likely predictors or 
leading indicators of a potential significant event. The 2015 target for process safety events was established equal to the 
baseline of events that occurred on our installations in 2014. In 2015, the reduction in the number of process safety events 
resulted in 108% achievement of the Process Safety metric and a formulaic result for this measure of 11% of the total 
target bonus opportunity for each of the Named Executive Officers. 

Financial Performance 

Cash Flow Value Added   

Thirty percent of the target award opportunity for each Named Executive Officer under the 2015 Cash Bonus 

Plan was based upon our achievement of Cash Flow Value Added (“CFVA”) relative to the CFVA delivered in 2014. 

The  CFVA  performance  measure  is  designed  to  measure  the  generation  of  cash  returns  in  excess  of  the 
Company’s cost of capital. CFVA is equal to Earnings Before Interest, Depreciation and Amortization (“EBIDA”) less a 

P-55 

 
 
 
 
 
 
 
 
 
 
charge for Average Capital (defined below) that is based on the weighted average cost of capital multiplied by Average 
Capital. 

•  EBIDA is calculated as net income (loss) before extraordinary items, plus depreciation expense, plus (minus) 
net interest (income) expense, plus (minus) loss (gain), net of tax, on all unusual items, plus expenditures 
related to approved long-term investments. 

• 

“Average  Capital”  is  equal  to  total  equity,  plus  total  long-term  debt  (book  value),  minus  cash  and  cash 
equivalents,  minus  goodwill,  plus  capitalized  lease  obligations  under  GAAP  (short  and  long  term),  plus 
accumulated depreciation on fixed assets, plus incremental capital expenditures during the year, minus capital 
expenditures related to newbuilds and other approved long-term investments. 

•  For the purpose of calculating CFVA in 2015, the weighted average cost of capital was set at 9% at the start 

of the year. 

Our method for setting the CFVA target is intended to improve the relationship between expected payouts and 
returns for shareholders. Performance was calculated on a sliding scale that measures our CFVA improvement in 2015 
relative to our CFVA performance in 2014, adjusted to ensure consistency in the year-over-year calculation. This approach 
strongly focuses management on improving the CFVA generated from our existing assets, disposing of assets with poor 
CFVA  generation  prospects,  and  making  investments  that  build  our  company  and  enable  us  to  deliver  long-term 
improvements in performance. Under this model, if management delivers performance to earn the weighted average cost 
of capital on the increase in Average Capital, then our CFVA will be the same as in the prior year, which will provide a 
target bonus for this performance measure. If our CFVA improves by an amount equal to or greater than 4% of the Average 
Capital at the end of the prior year, a bonus equal to 200% of the target bonus will be earned for this performance measure. 
Similarly, if our CFVA declines by an amount equal to or greater than 4% of the Average Capital at the end of the prior 
year, a bonus equal to 0% of the target bonus will be earned for this performance measure. The bonus multiple will be 
determined on a straight- line basis between these end points. 

We achieved a CFVA of $76 million in 2015 which resulted in a payout of 75% of the target bonus amount for 
this performance component, in accordance with this methodology, and a formulaic result for this measure of 22% of the 
total target bonus opportunity for each of the Named Executive Officers.   

Revenue Efficiency   

The Revenue Efficiency measure represented 20% of the total target annual bonus opportunity, with potential 

payouts ranging from 0% to 40% of the total target bonus amount based on actual performance. 

Revenue  Efficiency performance  measure  is  designed  to  measure  the  efficient  operation  of  each  rig  through 
maximizing available revenue while meeting all customer contract commitments. This measure creates a direct line of 
sight to the operational performance of those rigs under contract, with a sharp focus on continuous improvement.   

Revenue Efficiency is expressed as a percentage and defined as: 

•  The actual contract drilling revenues for a measurement period, divided by   
•  The maximum revenue calculated for the measurement period.   

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 minimum-target-maximum performance range for this measure was set at 93.1% - 94.7% - 95.5%, with zero 
payout  at  or  below  the  performance  range  minimum,  100%  of  bonus  opportunity  at  target  and  200%  of  target  bonus 
opportunity at or above the performance range maximum. The target opportunity set at 94.7% reflected 2014 actual results, 
which was increased significantly over 2013 results at 91.7%. The range maximum set at 95.5% represented a significant 

P-56 

 
 
 
 
 
 
 
 
 
 
improvement or “stretch” target. The bonus multiple was determined on a straight-line basis between the minimum and 
maximum end points. 

We achieved a Revenue Efficiency of 96.0% in 2015 which resulted in a payout of 200% of the target bonus 
amount for this performance component, in accordance with this methodology, and a formulaic result for this measure of 
40% of the total target bonus opportunity for each of the Named Executive Officers. 

Operating Costs   

The Operating Costs measure represented 20% of the total target annual bonus opportunity, with potential payouts 

ranging from 0% to 40% of the total target bonus amount based on actual performance. 

The Operating Costs performance measure is designed to focus on optimizing an efficient cost structure in support 
of earnings objectives. This type of measure is critical when downward pressure is exerted on the Company’s revenue 
stream during the current industry downturn. 

Operating Costs include Operating and Maintenance (O&M) expenses and General and Administrative (G&A) 
as shown in our income statement which are then adjusted for changes in activity levels that were not forecast when the 
target was set at the beginning of the year. 

The  minimum-target-maximum  performance  range  for  this  measure  was  set  based  on  the  Company’s  2015 
internal operating cost budget. Target performance was set at the Company’s established budget, with a minimum and 
maximum range of achievement set at approximately $150 million above or below target. The established 2015 cost budget 
target was adjusted down during the year to normalize for reduced rig activity. The bonus multiple was determined on a 
straight-line basis between the minimum and maximum end points and reflected 2015 operating cost savings that exceeded 
our target by over $200 million.     

The specific minimum-target-maximum values are not disclosed in this section, due to the proprietary nature of 

this information in establishing the Company’s competitive position in the market. 

A  sharp  focus  on  driving  costs  down  in  2015,  including  process  improvements  and  significant  actions  to 
streamline  operations, resulted  in  a payout of 200%  of  the target bonus  amount  for  this  performance  component. This 
performance resulted in a formulaic result for this measure of 40% of the total target bonus opportunity for each of the 
Named Executive Officers. 

Actual Bonus Plan Compensation for 2015 

Based on the performance measures described above and using the pre-determined weighting assigned to each 
measure by the Compensation Committee, the formulaic bonus outcome for each of our Named Executive Officers was 
150% of targeted bonus opportunity under the Performance Award and Cash Bonus Plan for 2015. The components of this 
total bonus payout under the Performance Award and Cash Bonus Plan for 2015 are as follows:

With the formulaic bonus outcome confirmed at 150%, the Compensation Committee then applied a qualitative 
assessment of annual performance in determining final bonus awards. Specifically, the Committee considered the impact 
of early contract cancellations during 2015 on the Cash Flow Value Added performance result. With the application of 
discretion, the Committee reduced the final bonus outcome for our Named Executive Officers to 140% of each executive’s 

P-57 

 
 
 
 
 
 
 
 
 
 
 
 
target bonus opportunity. For specific award amounts, see “Executive Compensation—Summary Compensation Table” 
below. 

Long-Term Incentives   

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

To provide an appropriate balance of incentives tied to performance, two types of long-term equity instruments 
were  used  in  2015,  including  Performance  Units  and  Restricted  Share  Units.  The  forms  of  equity  awards  and  their 
weightings made to our Named Executive Officers are discussed in greater detail below.

(1) Messrs. Thigpen and Mey’s 2015 LTI awards were granted on their hire dates of April 22 and May 28, respectively. 

Given the timing of Mr. Newman’s departure and the interim nature of Mr. Strachan’s role, neither were granted 

equity awards in 2015. 

Performance Units   

The  target  value  of  the  2015  Performance  Unit  (“PSU”) grants  to  each  of  the  Named  Executive  Officers  was 

approximately one-half (50%) of  each officer’s total 2015 long-term incentive award target value. 

Each PSU represents one share and is earned based on performance over a three-year performance cycle. In 2014, 
the  Compensation  Committee  added  a  financial-based  absolute  metric  of  return  on  capital  employed  (“ROCE”)  to 
complement the existing market-based performance measure of total shareholder return of the Company relative to the 
Performance Peer Group. Performance is determined by comparing the Company’s actual ROCE performance in the first 
calendar year of the performance cycle against the ROCE goal approved by the Compensation Committee, and measuring 
relative TSR performance against the Company’s Performance Peer Group over the three-year performance cycle. Each 
of  the  two  performance  measures,  total  shareholder  return  and  return  on  capital  employed,  are  weighted  equally  in 
determining the earned award, with maximum performance in both measures resulting in an earned award of 200% of 
target. 

Threshold performance, with respect to total shareholder return, is total shareholder return ranking at or above 
the  25th  percentile  of  the  Performance  Peer  Group,  at  which  25%  of  the  target  award  tied  to  this  measure  is  earned. 
Performance ranking below the 25th percentile results in no award being earned with respect to total shareholder return. 

Target performance, with respect to total shareholder return, is performance ranking at or above the median of 

the Performance  Peer Group, at which 50% of the target award is earned. 

At maximum performance with respect to total shareholder return, which is considered to be ranking at the top 
of the Performance Peer Group (or at or above the 90th percentile of the Performance Peer Group in the event that any 
peer ceases to be publicly traded), 100% of the target award is earned. 

P-58 

 
 
 
 
 
 
 
 
 
 
 
 
 
With respect to the return on capital employed PSU measure, a range of performance outcomes have been defined 
to set the threshold, target and maximum performance levels for this measure. In setting the ROCE goal, the Committee 
believed that achieving results at the target level would be challenging and substantially uncertain and achieving results 
meaningfully above target would be extremely difficult but not unattainable. 

Upon completion of the 2015 - 2017 PSU performance cycle, the Compensation 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   

The target value of the 2015 Restricted Share Unit (“RSU”) grants to each of the Named Executive Officers was 

approximately one-half (50%) of each officer’s total 2015 long-term incentive award target value. 

Time-vested RSUs were granted to all Named Executive Officers as part of the 2015 annual long-term incentive 
grants. Each RSU represents one share and vests over a three-year schedule (ratably one-third each year), contingent on 
continued service. 

Long-Term Incentive Compensation for 2015 

In 2016, the Compensation Committee evaluated the Company’s TSR relative to the Performance Peer Group, 
for  the  three-year  performance  period  from  January  1,  2013  through  December  31,  2015,  and  determined  that  the 
Company’s performance fell below threshold. 

Threshold performance is total shareholder return equal to or above the 25th percentile of the Performance Peer 
Group, at which 25% of the target award is earned. Performance below the 25th percentile results in no award being earned. 

The result of this determination, by the Compensation Committee, was that no PSUs were earned. The PSUs 

granted to executives for the 2013-2015 performance period were canceled for no value.   

Employment Agreements with Named Executive Officers   

In 2015, we entered into employment agreements with the three members of our Executive Management Team 
in compliance with the Minder Ordinance. Specifically, the Minder Ordinance prohibits the payment of severance benefits 
to members of the Executive Management Team, and they are therefore no longer eligible for severance benefits under the 
Executive Severance Benefit Policy. Other than the individual compensation terms applicable for each executive, the same 
form  of  employment  agreement  was  used  for  all  three  members  of  the  Executive  Management  Team.  Since  Messrs. 
Thigpen and Mey joined the Company in 2015, their agreements included (1) specified annual cash bonus targets for 2015, 
(2)  specified  equity  award  targets  under  the  Transocean  Ltd.  2015  Long  Term  Incentive  Plan  (the  “LTIP”)  and  (3) 
replacement  awards  of  cash  and  equity  in  consideration  of  the  forfeited  equity  awards  from  previous  employment.  In 
contrast,  Mr.  Stobart’s  agreement  was  a  restatement  of  his  existing  financial  arrangement.  All  three  members  of  the 
Executive Management Team will receive normal relocation and expatriate allowances consistent with the Company’s 
policy for U.S. national expatriate employees working in Switzerland.   

Expatriate Benefits   

For our Named Executive Officers who accept an international assignment, we also provide certain expatriate 
benefits, including housing, car, cost of living allowances and educational expenses for dependent children. These benefits 
are designed to help defray the significant expense associated with expatriation. The types and values of these benefits for 
each Named Executive Officer are included in the Summary Compensation Table under “All Other Compensation” and 
described in the notes to that table.   

Beginning  in  2014,  the  above-mentioned  expatriate  benefits  are  no  longer  eligible  for  tax  protection  or  tax 

equalization. 

P-59 

 
 
 
 
 
 
 
 
 
 
Indirect Compensation 

In addition to base salary and annual and long-term incentive compensation, we offer other 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  principal  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, pension, medical and life insurance benefits. Our Named Executive Officers also 
receive a supplemental life insurance benefit equal to four times covered annual earnings. For Named Executive Officers 
on the U.S. payroll, this benefit is capped at a maximum of $1 million. In addition, we make a supplemental pension 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   

We offer limited perquisites as a recruiting and retention tool. Each of our Named Executive Officers may receive 
reimbursement of up to $5,000 in financial planning consulting. Our Named Executive Officers are also eligible to receive 
reimbursement  for  club  membership  dues  and  an  annual  physical  exam  paid  by  the  Company.  The  amounts  of  these 
perquisites were taxable to the Named Executive Officers in 2015. 

The  Compensation  Committee  annually  reviews  the  nature  and  amount  of  the  perquisites  and  other  personal 
benefits provided to each of our Named Executive Officers to ensure that such perquisites are reasonable and competitive 
with market practice. 

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. Currently, all Named Executive 
Officers who are not members of our Executive Management Team are covered under our executive severance benefit 
policy, which provides for specified payments and benefits in the event of a termination at our convenience. 

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 
targeted award level under the Bonus Plan for such executive, as determined by the Compensation Committee; treatment 
of long-term incentive awards under the convenience-of-company termination provision as provided for in the terms and 
conditions  of  each  award  (as  more  fully  described  under  “Executive  Compensation—Potential  Payments  Upon 
Termination or Change of Control”); and outplacement services not to exceed 5% of the base salary of the executive. 

We also believe that the interests of our shareholders are served by including a double-trigger change-of-control 
provision in the Bonus Plan and the Long-Term Incentive Plan for Named Executive Officers who would be integral to 
the success of, and are most likely to be impacted by, a change of control. By requiring two triggering events to occur, we 
believe that those Executive Officers who remain with us through a change of control will be appropriately focused while 
those who depart as a result 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,  2015,  are  described  under  “Executive 
Compensation-Potential Payments Upon Termination or Change in Control.” 

The  Compensation  Committee  periodically  reviews  severance  packages  offered  to  the  Executive  Officers  to 
ensure the benefits are aligned with prevailing market practices. In order for a Named Executive Officer to receive the 

P-60 

 
 
 
 
 
 
 
 
benefits described above, the Named Executive Officer must first sign a release of all claims against the Company and 
enter into a Confidentiality Agreement covering our trade secrets and proprietary information. 

In  2015,  Mr.  Newman  and  Mr.  Ikaheimonen  each  entered  into  separation  agreements  with  the  Company  in 
connection with their terminations of employment. Under their respective separation agreements, Mr. Newman and Mr. 
Ikaheimonen  each  received  severance  payments  consistent  with  their  respective  2013  employment  agreements,  which 
incorporated the terms of the executive severance benefits policy by reference, as described above and included in the 
Summary Compensation Table, and the Minder Ordinance’s grandfathering provisions. Mr. Strachan and Mr. Sjobring did 
not receive any compensation in connection with their termination of employment. 

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  Compensation  Committee  is  responsible  for  the  executive  compensation  program  design  and  decision-
making process. The Compensation Committee solicits input from the independent members of the Board of Directors, 
the Chief Executive Officer and 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 Compensation 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 Compensation Committee is responsible for: 

• 

• 

• 

• 

• 

• 

• 

reviewing and approving the target and actual compensation paid and the benefit levels received by our 
Executive Officers; 

annually recommend 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 Compensation 
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 LTIP, including determining plan eligibility and approving individual awards 
for all plan participants; 

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

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

reviewing and discussing this Compensation Discussion and Analysis with our management and, based 
upon such review and discussion, recommending to the Board of Directors that the Compensation 

P-61 

 
 
 
 
 
 
 
 
 
 
 
Discussion and Analysis be included in the proxy statement for our Annual General Meeting; and 

• 

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

The Compensation Committee currently consists of four directors: Tan Ek Kia (Chairman), Frederico F. Curado, 

Vincent J. Intrieri and Martin B. McNamara. 

Independent Compensation Consultant 

To  assist  in  discharging  its  responsibilities,  the  Compensation  Committee  engaged  an  independent  executive 
compensation  consulting  firm,  Pay  Governance  LLC,  which  advised  the  Compensation  Committee  on  executive 
compensation matters for 2015. 

In order not to impair the independence of the Compensation Committee’s compensation consultant or create the 
appearance of such an impairment, the Compensation Committee adopted a policy that any compensation consultant to 
the  Compensation  Committee  may  not  provide  other  services  to  the  Company  in  excess  of  $100,000.  Neither  Pay 
Governance nor any of its affiliates provided the Company with any other services in 2015. In May 2015, the Compensation 
Committee assessed whether the work of Pay Governance for the Compensation Committee during 2015 raised any conflict 
of interest by conducting a review of a number of independence factors, which included the factors set forth under Rule 
10C-1 of the Exchange Act. The Compensation Committee concluded that no conflict of interest was raised that would 
prevent Pay Governance from independently representing the Compensation Committee. 

In advising the Compensation Committee, the compensation consultant reports to and acts at the direction of the 
Compensation Committee. The Compensation 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 group; 

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 Compensation Committee conducts its analysis of and makes its decisions regarding 
executive compensation. 

The  Compensation  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 Compensation Committee and meets privately 
with the Compensation Committee at the Compensation 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  Compensation 
Committee, regarding executive compensation matters. Such advisors have included, among others, an outside corporate 
law firm to provide advice regarding various legal issues, financial analysts to examine relevant performance metrics and 
an  outside  actuarial  firm  to  evaluate  benefits  programs.  The  Compensation  Committee  evaluates  these  advisors  for 
independence, when retained. 

P-62 

 
 
 
 
 
 
 
 
 
 
 
 
 
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 Compensation Committee. The 
Compensation Committee makes all compensation decisions and approves all share-based awards for the Named Executive 
Officers  and  other  Executive  Officers.  The  Compensation  Committee  may  exercise  its  discretion  in  modifying  any 
compensation adjustment or awards 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  Compensation 
Committee  as  needed.  Our  officers  and  other  employees  participate  in  Compensation  Committee  discussions  in  an 
informational and advisory capacity and have no authority in the Compensation Committee’s decision-making process. 

Additional Executive Compensation Information 

Use of Tally Sheets   

The  Compensation  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 hypothetical terminations 
to consider the Company’s obligations under such circumstances. The Compensation 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  minimum 
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 taxes due) 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  Compensation  Committee,  and  executives  must  certify  their 
compliance  on  an  annual  basis.  The  Compensation  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 of our Executive Officers and directors from pledging shares issued by us. 

P-63 

 
 
 
 
 
 
 
 
 
Our Executive Officers and directors must certify compliance with the hedging and pledging provisions of our 

Insider Trading Policy  on an annual basis. 

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 Compensation Committee determines that payments or awards have exceeded the amount 
that  would  otherwise  have  been  received,  due  to  a  restatement  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 requirement. 

The Compensation Committee expects to modify this policy after 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 LTIP, the Compensation Committee has the discretion to award performance-based cash compensation 
that qualifies under Section 162(m) based on the achievement of objective performance goals. All Executive Officers are 
eligible to receive this type of award. The Compensation Committee has determined, and may in the future determine, to 
award compensation that does not qualify under Section 162(m) as performance-based compensation.

(1)  Base salary is denominated in U.S. dollars (US$). Messrs. Strachan, Ikaheimonen and Sjobring’s salaries were paid in Swiss francs (CHF) but, for 
purposes  of  this  table,  converted  to  US$  using  the  average  annual  CHF  to  US$  exchange  rates  of  1.04028  and  1.07895  for  2014  and  2013, 
respectively. 

(2)  Represents the aggregate grant-date fair value under accounting standards for recognition of share-based compensation expense for the specified 
year. For a discussion of the valuation assumptions with respect to these awards, please see Note 17 to our consolidated financial statements included 
in our Annual Report on Form 10-K for the year ended December 31, 2015. 

(3)  Non-Equity Incentive Plan Compensation includes annual cash bonuses paid to the Named Executive Officers based on service during the year 
included in the table and awarded in the following year pursuant to the Performance Award and Cash Bonus Plan. The Performance Award and 
Cash Bonus Plan, including the performance targets used for 2015, is described under “Compensation Discussion and Analysis—Performance 
Award and Cash Bonus Plan.” 
There are no nonqualified deferred compensation earnings included in this column because no Named Executive Officer received above-market or 
preferential earnings on such compensation during 2015, 2014 or 2013. 
Ian C. Strachan served as Interim President and Chief Executive Officer from February 16, 2015 through April 21, 2016.

Transocean U.S. Retirement Plan 

The Transocean U.S. Retirement Plan is a tax-qualified pension plan funded through cash contributions made by 
the Company based on actuarial valuations and regulatory requirements. Messrs. Newman, Stobart, and Tonnel were the 
Named Executive Officers in 2014 who participated 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.  Employees  working  for  the 
Company in the U.S. are fully vested after completing five years of eligible employment. Benefits available to the Named 
Executive Officers are no greater than those offered to non-executive participants. 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).  Effective  as  of 
January 1, 2015, the Company authorized the amendment of the Plan in order to freeze benefits under the Plan effective 
as of December 31, 2014. 

The following elements of executive compensation are included in computing the retirement benefit: base salary, 
non-equity  incentive  plan  compensation  and  special  performance  cash  bonuses.  Retirement  benefits  are  calculated  as 
(1) the product of (A) each year of an employee’s credited service, times (B) 2.00%, times (C) the final average earnings, 
minus (2) the product (also referred to as the “Offset”) of (A) each year of an employee’s credited service, times (B) 0.65%, 
times  (C) the  final  average  social  security  earnings.  However,  the  Offset  cannot  be  greater  than  one-half  of  the  gross 
benefit, calculated using the lesser of the final average earnings and final average Social Security earnings. 

If  the  employee  elects  to  retire  between  the  ages  of  55  and  64,  the  amount  of  benefits  is  reduced;  actuarial 
reduction factors are applied to his or her “gross benefit” and his or her final average Social Security earnings offset to 
allow for the fact that his or her benefit will start earlier than “normal” and will, therefore, be paid for a longer period of 
time. If the employee terminates service at age 55 or later, he or she may elect to receive an unreduced benefit as early as 
age 62. 

None of the Named Executive Officers met the eligibility requirements for “early retirement” under the plan. The 
gross benefit is reduced 2% per year for the first five years and 6% per year for the next five years that the early retirement

date precedes the normal retirement date. The offset benefit is reduced 6.67% per year for the first five years and 3.33% 
per year for the next five years that the early retirement date precedes the normal retirement date. 

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, 2014. The present value of these benefits was calculated based on assumptions used in the Company’s 
financial statements for 2013. The key assumptions used were: 

Interest Rate: 
Mortality: 
Form of Payment: 
Compensation: 
Retirement Age: 
Percentage Married: 

    4.58% 
   RP 2006    MP 2015 
   Joint & 50% Survivor Annuity 
   Base Salary + Non-Equity Incentive Plan Compensation 
   62 
   70% Male—60% Female 

Transocean Pension Equalization Plan 

Officers, including each of the Named Executive Officers, are eligible to receive a benefit from the Company’s 
nonqualified,  unfunded,  noncontributory  Pension  Equalization  Plan  (“PEP”)  if  the  level  of  their  compensation  would 
otherwise cause them to exceed the Internal Revenue Code compensation limitations imposed on the Transocean U.S. 
Retirement Plan. The purpose of this plan is to recognize an executive’s service to the Company and provide supplemental 
post-retirement income to those individuals. 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 as the U.S. Retirement Plan. Benefits are not earned until 
the individual has five years of credited service with the Company. The formula used to calculate the plan benefit is the 
same as that which is used to calculate benefits under the Transocean U.S. Retirement Plan; however, earnings are not 
limited to the pay cap under the Internal Revenue Code Section 401(a)(17) ($265,000 in 2015). The plan was amended 
effective  January 1,  2015,  to  (1) freeze  benefits  under  the  plan  effective  as  of  December 31,  2014,  and  (2) change  the 
Applicable Interest Rate in effect on January 1, 2015. 

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, 2015. The present value of these benefits was calculated based on assumptions used in the Company’s 
financial statements for 2015.

Transocean International Retirement Savings Plan 

In January 2014, the Transocean International Retirement Plan and the Transocean International Savings Plan 
were  merged  into  one  trust-based  plan  called  the  Transocean  International  Retirement  Savings  Plan.  The  plan  is  a 
nonqualified, defined contribution plan, for non-U.S. citizen employees who accept international assignments and have 
completed at least one full calendar month of service. Eligibility in the plan is based on residency outside of the U.S. 
Mr. Tonnel was the only Named Executive Officer in 2015 who held accrued benefits in this plan, however, he did not 
actively participate in this plan in 2015. The plan is funded through cash contributions by the Company as a percentage of 
compensation along with voluntary contributions by employees, which are limited to 15% of the employee’s base pay. 

P-72 

 
 
 
 
 
 
 
 
 
 
Current Company contribution levels are as follows: 

Service 

Company Match 

< 5 years 
5 - 9 years 
10 - 14 years 
15 - 19 years 
20+ years 

4.5% 
5% 
5.5% 
6% 
6.5% 

Contributions are based on a participant’s compensation (regular pay, non-equity cash incentive pay and special 
performance cash awards). The normal retirement age under the plan is age 60; however, participants who are age 50 or 
older, and who are vested with two or more years of service, may upon termination or retirement, elect to receive a lump 
sum or an annuity based on the full cash value of the participant’s retirement account. If a participant retires with less than 
two years of service, the participant will only be entitled to receive benefits under the plan based on the accumulated value 
of his voluntary employee contributions. 

Transocean Management Ltd. Pension Plan 

The  Company  maintains  the  Transocean Management Ltd. Pension  Plan,  a nonqualified, defined  contribution 
plan, for its non-U.S. dollar paid employees in Switzerland. Messrs. Ikaheimonen, and Sjobring were the Named Executive 
Officers  in  2015  who  participated  in  this  plan.  The  plan  is  funded  through  cash  contributions  by  the  Company  as  a 
percentage of compensation along with contributions by employees. Mandatory contributions by the employees are 6% of 
pensionable salary. Additional voluntary contributions are permitted but these contributions do not generate any additional 
match by the Company. Current Company contribution levels are as follows: 

Age 
24 
34 
44 
54 

Company Match 
10% 
12% 
14% 
16% 

Contributions are based on a participant’s annual salary. Regular retirement age under the plan is age 65 for men 

and 64 for women, as is customary in Switzerland. 

Nonqualified Deferred Compensation for 2015

Transocean U.S. Supplemental Savings Plan 

The Named Executive Officers and certain other highly compensated employees as of December 31, 2008, were 
eligible to participate in the nonqualified, unfunded Transocean U.S. Supplemental Savings Plan if the level of their base 
salaries  would  otherwise  cause  them  to  exceed  the  contribution  limits  imposed  by  the  Internal  Revenue  Code  on  the 
Transocean U.S. Savings Plan. Base pay is used to calculate the benefit. The Company maintains on its books an account 
for each participant to whom it credits (1) the amount of any Company matching contributions which are not paid to the 
Transocean U.S. Savings Plan due to limitations of the Internal Revenue Code, plus (2) earned interest. This interest is 
credited at the end of each calendar quarter and is calculated as a sum that is equal to the average balance for the quarter 
multiplied  by  one-fourth  of  the  annual  prime  rate  for  corporate  borrowers  quoted  by  The  Federal  Reserve  Statistical 
Release at the beginning of the quarter. The participant’s supplemental savings benefit equals the balance recorded in his 
account. A participant receives a single lump sum payment of the balance at the time of such participant’s termination, or 
six  months  after  termination  in  the  case  of  certain  officers.  A  participant  may  not  receive  a  distribution  or  make  any 
withdrawals prior to such participant’s termination. On December 31, 2008, the Transocean U.S. Supplemental Savings 
Plan was frozen. No further benefits have accrued under the plan since December 31, 2008. 

Transocean Savings Restoration Plan 

The Company maintains the Transocean Savings Restoration Plan, a nonqualified, unfunded, defined contribution 
plan for key management employees, including each actively employed Named Executive Officer who earns compensation 
in excess of certain limits in the Internal Revenue Code. 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. A participant must be employed 
on the last day of the calendar year in order to receive a contribution for a particular year. 

Potential Payments Upon Termination or Change of Control 

The following tables and narrative disclosure set forth, as of December 31, 2015, certain information with respect 
to compensation that would be payable to the Named Executive Officers, still serving as officers of the Company as of 
December 31, 2015, upon a variety of termination or change of control scenarios. 

As of December 31, 2015, the Named Executive Officers still serving as officers of the Company were eligible 
for the executive severance benefit policy. Members of the Executive Management Team are further subject to the full 
limitations  of  the  Minder  Ordinance  regarding  severance  upon  expiry  of  the  grandfathering  provisions  of  the  Minder 
Ordinance in December 2015.

a six-month waiting period after their termination. No distributions or withdrawals are permitted prior to termination.

(1)  Any involuntary not-for-cause termination as of December 31, 2015, would have been calculated under the executive severance benefit and the 

Performance Award and Cash Bonus Plan. 

(2)  The terms and conditions of the non-qualified option awards provide that upon an involuntary, not-for-cause termination, any unvested options are 

canceled as of the date of termination. 

(3)  RSUs are awards that vest in equal installments over three years, on the first, second and third anniversaries of the date of grant. Upon an involuntary, 

(4) 

not-for-cause termination, all of the RSUs would vest. 
PSUs are based upon the achievement of a performance standard over a three-year period. The determination period for a portion of the PSUs ends 
on December 31, 2016, and the determination period for the remaining PSUs ends on December 31, 2017. The actual number of PSUs received will 
be determined in the first 60 days of 2017 of 2018, as applicable, and is contingent on our performance in total shareholder return relative to the 
Performance Peer Group. Upon an involuntary, not-for-cause termination, the Named Executive Officers would receive a pro-rata portion of the 
PSUs. The pro-rata portion of the PSUs is determined by multiplying the number of PSUs which would have otherwise been earned had the Named 
Executive Officer’s employment not been terminated by a fraction, the numerator of which is the number of calendar days he was employed during 
the performance cycle after the grant date and the denominator of which is the total number of calendar days in the performance cycle after the grant 
date. 

(5)  The amount of PEP benefits included in the table for each of Messrs. Stobart, Tonnel and Ms. Bonno represents the present value of those benefits 

which would not have been payable as of December 31, 2015, but would be payable once he reaches 55 years of age. 

(6)  The supplemental savings plan benefit is equal to the balance, which includes interest, recorded in each Named Executive Officer’s account as of 
December 31, 2015. Each of Messrs. Stobart, Tonnel and Ms. Bonno are eligible to receive a lump sum payment of the balance after a six-month 
waiting period after his termination. No distributions or withdrawals are permitted prior to termination.

compensation for 2015. If the Named Executive Officer died on December 31, 2015, then this pro-rata share would be equal to 100% of such 
Named Executive Officer’s targeted non-equity compensation for 2015. 
The unvested portions of the stock options and RSUs vest immediately upon death. 
The beneficiary of each Named Executive Officer is entitled to a pro-rata portion of PSUs upon such Named Executive Officer’s death. 
Each  Named  Executive  Officer  would  be  eligible  to  receive  the  same  supplemental  savings  plan  payments  as  contemplated  under  the 
“Involuntary Not-for-Cause Termination” scenario described above.

(1)  Restricted shares and deferred units are included in the awards we may grant under the LTIP, and 2,733,806 shares are available for future issuance 

pursuant to grants of restricted shares and deferred units. 

(2)  Does not include any shares that may be distributed under our deferred compensation plan, which has not been approved by our shareholders. Under 
this  plan,  our  directors  could  defer  any  fees  or  retainers  by  investing  those  amounts  in  Transocean Inc.  ordinary  share  equivalents  or  in  other 
investments selected by the administrative committee. Amounts that are invested in the share equivalents at the time of distribution are distributed 
in ordinary shares. After December 31, 2005, no further deferrals may be made under the plan. As of the time immediately prior to our merger with 
GlobalSantaFe, our directors had purchased 30,490 Transocean Inc. ordinary share equivalents under this plan. Each of the share equivalents was 
reclassified into 0.6996 share equivalents and $33.03 cash. Fractional share equivalents were paid in cash. The total cash consideration was used to 
purchase  additional  share  equivalents  using  the  closing  price  for  Transocean Inc.  ordinary  shares  on  November 27,  2007.  As  a  result  of  the 
redomestication  transaction  pursuant  to  which  Transocean Inc.  merged  by  way  of  schemes  of  arrangement  under  Cayman  Islands  law  with 
Transocean Cayman Ltd., with Transocean Inc. as the surviving company, each Transocean Inc. ordinary share equivalent was exchanged for a 
Transocean Ltd.  share  equivalent.  For  the  years  ended  December 31,  2015  and  2014,  our  directors  held  18,156  and  20,275  share  equivalents, 
respectively, under the plan.

Compensation Committee Interlocks and Insider Participation 

OTHER MATTERS 

The members of the Compensation Committee of the Board of Directors during 2015 were Tan Ek Kia, Chairman, 
Frederico F. Curado, Vincent J. Intrieri and Martin B. McNamara. 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  Securities  and  Exchange  Commission.  Based  solely  on  a  review of such reports 
furnished  to  the  Company  and  written  representations  that  no  report  on  Form 5  was  required  for  2015,  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 2015. 

Householding 

The SEC permits us, under certain circumstances, to send a single set of the Notice of Internet Availability of 
Proxy Materials, 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 Notice of Internet Availability of Proxy 
Materials 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 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 that 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 proxy materials 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  2017  Annual  General  Meeting,  your 
proposals must be received at our principal executive offices c/o Transocean Management Ltd., 10 Chemin de Blandonnet, 
CH-1214 Vernier, Switzerland by no later than November 18, 2016 at 5:00 p.m., Swiss time. However, if the date of the 
2017 Annual General Meeting changes by more than 30 days from the anniversary of the 2016 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. 

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 

P-78 

procedures set forth in our Articles of Association. Our Articles of Association provide generally that, if you desire to 
propose any business at an Annual General Meeting (including the nomination of any director), you must give us written 
notice at least 30 calendar days prior to the anniversary date of the proxy statement in connection with Transocean’s last 
Annual General Meeting; provided, however, that if the date of the Annual General Meeting is 30 calendar days before or 
after the anniversary date of the last Annual General Meeting, such request must instead be made by the tenth day following 
the date on which we have made public disclosure of the date of the Annual General Meeting. The deadline under our 
Articles of Association for submitting proposals will be February 16, 2017 at 5:00 p.m., Swiss Time for the 2017 annual 
meeting unless it is more than 30 calendar days before or after May 12, 2016. 

In  order  for  the  notice  to  be  considered  timely  under  Rule 14a-4(c)  of  the  Exchange  Act,  proposals  must  be 
received no later than February 16, 2017 at 5:00 p.m., Swiss Time. The request must specify the relevant agenda items and 
motions,  together  with  evidence  of  the  required  shareholdings  recorded  in  the  share  register,  as  well  as  any  other 
information as would be required to be included in a proxy statement pursuant to the rules of the SEC. 

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

• 

• 

• 

• 

• 

• 

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

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

a  representation  that  you  intend  to  appear  in  person  or  by  proxy  as  a  holder  of  record  at  the  meeting  to 
nominate the person or persons specified in the notice; 

a description of all arrangements or understandings between you and each nominee you propose and any 
other person or persons under which the nomination or nominations are to be made by you; 

any other information regarding each nominee you propose that would be required to be included in a proxy 
statement filed pursuant to the proxy rules of the SEC; and 

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

The Board of Directors may refuse to transact any business or to acknowledge the nomination of any person if 
you fail to comply with the foregoing procedures. You may obtain a copy of our Articles of Association and Organizational 
Regulations, in which these procedures are set forth, upon written request to our Corporate Secretary, Transocean Ltd., 
Turmstrasse 30, CH-6300 Zug, Switzerland. 

Cost of Solicitation 

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

P-79 

Forward-Looking Statements 

The statements included in this proxy statement, including in the letter to shareholders and in the section entitled 
“Compensation  Discussion  and  Analysis—Executive  Summary—2015  Business  Overview,”  regarding  future  financial 
performance, results of operations, liquidity, stacking of assets and the market and other statements that are not historical 
facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of 
the Exchange Act. Forward-looking statements are subject to numerous risks, uncertainties and assumption, including, but 
not limited to, the future prices of oil and gas, operating hazards and delays, actions by customers and other third parties, 
conditions in the drilling industry and in the capital markets and those described under “Item 1A. Risk Factors” in the 2015 
Annual Report and in our other filings with the SEC. Should one or more of these risks or uncertainties materialize (or the 
other consequences of such a development worsen), or should underlying assumptions prove incorrect, actual results may 
vary materially from those indicated or expressed or implied by such forward-looking statements. All subsequent written 
and oral forward-looking statements attributable to us or to persons acting on our behalf are expressly qualified in their 
entirety by reference to these risks and uncertainties. You should not place undue reliance on forward-looking statements. 
Each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to 
publicly update or revise any forward-looking statements, except as required by law.

Zurich, March 9, 2016 

Report of the statutory auditor on the compensation report 
We have audited the compensation report (pages CR-2 to CR-6) of Transocean Ltd. for the year ended December 31, 2015. 

Responsibility of the Board of Directors 
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,  2015  of  Transocean Ltd.  complies  with  Swiss  law  and 
articles 14 – 16 of the Ordinance.

2016, with the last trading day scheduled to be March 30, 2016.  Our shares will continue to be listed and traded on the NYSE.

presented above reflect changes that resulted from translation of the U.S. dollar amounts for presentation in the statutory financial statements. 

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.    Directors  who  are  our 
employees do not receive compensation for board service.  With the exception  of Jeremy Thigpen, all of the directors on our Board of 
Directors  are  non-employees  and  receive  compensation.    Ian  Strachan  served  both  as  a  member  of  the  Executive  Management  Team 
from February 16, 2015 to April 22, 2015 and as a member of our Board of Directors until May 15, 2015. 

We grant restricted share units to each non-employee director and the non-executive chairman annually with an aggregate value 
of USD 210,000 and USD 325,000, 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, share 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.

(a)  We  granted  restricted  share  units  to  the  members  of  our  Executive  Management  Team  as  follows:  Messrs. Ikaheimonen  and  Stobart  on  February 13,  2015; 

Mr. Thigpen on April 22, 2015; and Mr. Mey on May 28, 2015. 

(b)  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  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. 

(c)  We granted the performance share units to the members of our Executive Management Team.  The actual number of share units earned will be determined in the first 
60 days of 2018, contingent upon our total shareholder return relative to our performance peer group and our performance against established targets for return on 
capital employed.  The three-year performance period is January 1, 2015 to December 31, 2017.  The number of performance share units reflects the target number of 
shares  for  the  award.    Actual  shares  earned  and  allocated  will  be  determined  based  on  performance  thresholds  and  may  range  between  zero and  two shares  per 
performance share unit. 

(d)  Total share-based compensation in 2015 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 tax contributions at the statutory rate prevailing at 
the time income is earned.

measurement is evaluated over the three-year performance period ending December 31, 2016.    The number of performance share units reflects the target number of

Credits and Loans Granted to Governing Bodies 

In compliance with Article 29f paragraph 1 of our Articles of Association, which our shareholders adopted at the annual general 
meeting held in  May 2014,  we  did  not  grant  credits  or  loans  to  active  or  former  members  of  our  Board  of  Directors,  members  of 
our  Executive  Management  Team  or  to  any  other  related  persons  during  the  years  ended  December 31,  2015  and  2014.    At

Item 1. 

Business 

Overview 

Transocean Ltd.  (together  with  its  subsidiaries  and  predecessors,  unless  the  context  requires  otherwise,  “Transocean,”  the 
“Company,”  “we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas  wells.    As  of 
February 11, 2016, we owned or had partial ownership interests in and operated 61 mobile offshore drilling units.  As of February 11, 2016, 
our  fleet  consisted  of  28 ultra-deepwater  floaters,  seven harsh  environment  floaters,  five deepwater  floaters,  11 midwater  floaters  and 
10 high-specification jackups.  At February 11, 2016, we also had six ultra-deepwater drillships and five high-specification jackups under 
construction or under contract to be constructed. 

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 
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 floaters and high-specification jackups 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 Chemin de Blandonnet 10, 1214 Vernier, Switzerland.  Our telephone number at that address is +41 22 930-9000.  Our 
shares are listed on the New York Stock Exchange (“NYSE”) under the symbol “RIG” and on the SIX Swiss Exchange (“SIX”) under the 
symbol  “RIGN”  (see  “—Recent  Developments”).    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 22—Operating Segments, Geographical Analysis and Major Customers.” 

Recent Developments 

On November 23, 2015, we announced our intent to delist our shares from the SIX, and on December 17, 2015, we announced 
that the SIX listing authorities approved our application to delist our shares.  Such delisting is expected to become effective on March 31, 
2016, with the last trading day scheduled to be March 30, 2016.  Our shares will continue to be listed and traded on the NYSE. 

On October 29, 2015, shareholders at our extraordinary general meeting 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  par  value  reduction  became  effective  as  of  January 7,  2016  upon 
registration in the commercial register. 

On  August 5,  2014,  we  completed  an  initial  public  offering  to  sell  a  noncontrolling  interest  in  Transocean Partners LLC 
(“Transocean Partners”),  a  consolidated  Marshall  Islands  limited  liability  company,  which  trades  on  the  NYSE  under  the  ticker  symbol 
“RIGP”.    Through  Transocean Partners Holdings Limited,  a  Cayman  Islands  company  and  our  wholly  owned  subsidiary,  we  hold  the 
controlling  interest  with  21.3 million  common  units  and  27.6 million  subordinated  units  and  all  of  the  incentive  distribution  rights.    See 
“Part II.  Item 8.  Financial  Statements  and  Supplementary  Data—Notes  to  Consolidated  Financial  Statements—Note 15—Noncontrolling

Drilling Fleet 

Fleet  overview—Most  of  our  drilling  equipment  is  suitable  for  both  exploration  and  development  drilling,  and  we  normally 
engage in both  types of drilling  activity.  Likewise, 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.  Our drilling 
fleet can be generally characterized as follows: (1) floaters, including drillships and semisubmersibles, and (2) jackups. 

Drillships are generally self-propelled vessels, shaped like conventional ships, and are the most mobile of the major rig types.  All 
of  our  high-specification  drillships  are  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.    Drillships  typically  have 
greater  deck  load  and  storage  capacity  than  early  generation  semisubmersible  rigs,  which  provides  logistical  and  resupply  efficiency 
benefits for customers.  Drillships are generally better suited to operations in calmer sea conditions and typically do not operate in areas 
considered to be harsh environments.  We have 13 ultra-deepwater drillships in operation that are, and six 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, reducing critical path activity, to improve 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, 
four of our six 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 
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.  We have three semisubmersibles, which are designed for mild 
environments and are equipped with the unique tri-act derrick.  The tri-act derrick was designed to reduce overall well construction costs, 
as it allows offline tubular and riser handling operations to occur at two sides of the derrick while the center portion of the derrick is being 
used for normal drilling operations through the rotary table.  Additionally, five of our 30 semisubmersibles are equipped with our patented 
dual-activity technology. 

Jackup  rigs  are  mobile  self-elevating  drilling  platforms  equipped  with  legs  that  can  be  lowered  to  the  ocean  floor  until  a 
foundation is established to support the drilling platform.  Once a foundation is established, the drilling platform is then jacked further up the 
legs so that the platform is above the highest expected waves.  These rigs are generally suited for water depths of 400 feet or less.  We 
have five newbuild high-specification jackups under construction that are expected to be capable of constructing wells up to 35,000 feet 
deep and feature advanced offshore drilling technology, including offline tubular handling features and simultaneous operations support. 

Fleet  categories—We  further  categorize  the  drilling  units  of  our  fleet  as  follows:  (1) “ultra-deepwater  floaters,”  (2) “harsh 

environment floaters,” (3) “deepwater floaters,” (4) “midwater floaters” and (5) “high-specification jackups.” 

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.    High-specification  jackups  have  high  capacity  derricks,  drawworks,  mud  systems  and  storage  and  generally  have  a  water 
depth capacity of between 350 and 400 feet. 

As of February 11, 2016, we owned and operated a fleet of 61 rigs, excluding rigs under construction, as follows: 

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

28 ultra-deepwater floaters; 
Seven harsh environment floaters; 
Five deepwater floaters; 
11 midwater floaters; and 
10 high-specification jackups. 

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 30 to 60 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 11,  2016,  provide  certain  specifications  for  our  rigs.    Unless 
otherwise noted, the stated location of each rig indicates either the current drilling location, if the rig is operating, or the next operating 
location, if the rig is in shipyard with a follow-on contract.  As of February 11, 2016, we owned all of the drilling rigs in our fleet noted in the 
tables below, except for the following: (1) those specifically described as being owned through our interests in consolidated entities that 
were less than wholly owned and (2) Petrobras 10000, which is subject to a capital lease through August 2029.

Markets 

Our  operations  are  geographically  dispersed  in  oil  and  gas  exploration  and  development  areas  throughout  the  world.    We 
operate in a single, global offshore drilling market, as our drilling rigs are mobile assets and are able to be moved according to prevailing 
market conditions.  We may mobilize our drilling rigs between regions for a variety of reasons, including to respond to customer contracting 
requirements or 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 11,  2016,  our  drilling  fleet  was  located  in  the  U.K. North Sea (13 units),  U.S. Gulf of Mexico (10 units), 
India (two units),

United Arab Emirates (one unit). 

We  categorize  the  market  sectors  in  which  we  operate  as  follows:  (1) ultra-deepwater,  (2) deepwater,  (3) midwater  and 
(4) jackup.  The ultra-deepwater, deepwater and midwater market sectors, collectively known as the floater market, are serviced by our 
drillships and semisubmersibles, seven 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 jackup 
market sector begins at the outer limit of the transition zone, which is characterized by coastal and state water areas, extending to water 
depths of approximately 400 feet. 

The market for offshore drilling rigs and associated 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. 

At present, the industry is experiencing a cyclical downturn.  Sustained weak commodity pricing has resulted in our customers 
delaying investment decisions and postponing exploration and production programs.  Oil and natural gas prices do not currently support 
sustained demand for drilling rigs across all asset classes and regions.  As a result of this reduced demand, we have seen a sharp decline 
in the execution of drilling contracts for the global offshore drilling fleet and an unprecedented level of early drilling contract terminations.  
We  currently  expect  very  few  drilling  contracts  to  be  awarded  in  2016,  exacerbating  the  excess  rig  capacity  and  resulting  in  continued 
downward pressure on 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,  2015  and  2014,  we  sold  17 and  two drilling  units, 
respectively, for scrap value, and at December 31, 2015, we have five additional rigs classified as held for sale for scrap value. 

Despite  current  market  conditions,  our  long-term  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 meet 
global demand for hydrocarbons replacing reserves.  A number of new deepwater and ultra-deepwater development opportunities have 
been  identified  globally.    If  commodity  prices  stabilize  and  rebound  to  sustainable  levels,  we  anticipate  that  many  of  the  projects  will 
receive approval to move forward.  Many of 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 exploration and production companies operating in deeper water depths or 
other challenging environments or with complex well designs.

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,  2015,  the  contract  backlog  was  approximately  $16.0 billion,  representing  a  decrease  of 
29 percent and 43 percent, respectively, compared to the contract backlog at December 31, 2014 and 2013, which was $22.5 billion and 
$28.2 billion, respectively.  See “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—
Outlook—Drilling market” and “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 with customers 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 their obligations 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.” 

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, which is, in any case, immaterial to us.  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 14—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,  2015,  our  most  significant 
customers were Chevron Corporation (together with its affiliates, “Chevron”) and Royal Dutch Shell plc (together with its affiliates, “Shell”), 
representing  approximately  14 percent  and  10 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,  2015.    Additionally,  as  of 
February 11,  2016,  the  customers  with  the  most  significant  aggregate  amount  of  contract  backlog  associated  with  our  drilling  contracts 
were Shell and Chevron, representing approximately 51 percent and 21 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 financial results.” 

Employees 

We  require  highly  skilled  personnel  to  operate  our  drilling  units.    Consequently,  we  conduct  extensive  personnel  recruiting, 
training and safety programs.  At December 31, 2015, we had approximately 9,100 employees associated with our continuing operations, 
including approximately 500 persons engaged through contract labor providers.  Approximately 30 percent of our total workforce, working 
primarily  in  Angola,  the  U.K.,  Nigeria,  Norway,  Australia  and  Brazil  are  represented  by,  and  some  of  our  contracted  labor  work  under, 
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 apply to 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. 

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. 

Joint Venture, Agency and Sponsorship Relationships and Other Investments 

As of December 31, 2015, we held a 70.9 percent limited liability company interest in Transocean Partners.  On August 5, 2014, 
we completed the initial public offering of 20.1 million common units of Transocean Partners, which trades on the NYSE under the ticker 
symbol  “RIGP.”    During  the  year  ended  December 31,  2015,  Transocean Partners  repurchased  91,500 common  units  under  its  unit 
repurchase program, and at December 31, 2015, 20.0 million publicly traded common units remained outstanding.  We hold the remaining 
21.3 million common units and 27.6 million subordinated units of Transocean Partners and all of its incentive distribution rights. 

Additionally, 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 are an active participant 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 establishment of a relationship with a local agent or sponsor.  When appropriate in these areas, we enter into agency 
or sponsorship agreements.  Some of the joint ventures in which we participate are as follows: 

We  hold  a  65 percent  interest  in  ADDCL,  a  consolidated  Cayman  Islands  joint  venture  company  formed  to  own 
Discoverer Luanda,  which  operates  in  Angola.    Our  local  partner,  Angco  Cayman Limited,  a  Cayman  Islands  company,  holds  the 
remaining 35 percent interest in ADDCL.  Beginning January 31, 2016, Angco Cayman Limited will have 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  70 percent  interest  in  TDSOI,  a  consolidated  British  Virgin  Islands  joint  venture  company  formed  to  own 
Transocean Honor, which operates in Angola.  Our local partner, Angco II, a Cayman Islands company, holds the remaining 30 percent 

AR-8 

interest in TDSOI.  Under certain circumstances, Angco II will  have 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 jackup, 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. 

Additionally,  we  hold  interests  in  certain  joint  venture  companies  in  Angola,  Indonesia,  Malaysia  and  Nigeria  that  have  been 

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

Technological Innovation 

We are a leading international provider of offshore contract drilling services for oil and gas wells.  We specialize in technically 
demanding sectors of the global offshore drilling business.  Our fleet is considered one of the most versatile in the world with a particular 
focus on deepwater and harsh environment drilling capabilities.  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 and the first semisubmersible rig for year-round sub-Arctic operations.  In recent years, we have repeatedly achieved the 
world water depth record, holding the current world record at 10,411 feet.  Eighteen rigs in our existing fleet are, and six of our rigs that are 
currently 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.  Additionally, three rigs in our existing fleet are equipped with the unique tri-act derrick, which allows offline tubular 
and riser activities during normal drilling operations and is patented in certain market sectors in which we operate. 

We  continue  to  develop  and  deploy  industry-leading  technology.    In  addition  to  our  patented  dual-activity  drilling  technology, 
some of our most recent newbuild drillships will include industry-leading hookload capability, compensated cranes for performing subsea 
installations,  hybrid  power  systems  and  reduced  emissions  and  advanced  generator  protection.    The  newbuild  drillships  will  also  be 
outfitted with two blowout preventers and triple liquid mud systems and are designed to accept 20,000 psi blowout preventers in the future.  
The  effective  use  of  and  continued  improvements  in  technology  to  address  our  customers’  requirements  are  critical  to  maintaining  our 
competitive  position  within  the  contract  drilling  services  industry.    We  expect  to  continue  to  develop  technology  internally,  through 
partnerships, such as our collaboration with a customer to develop a fault-resistant and fault-tolerant blowout preventer control system, or 
to acquire technology through strategic acquisitions. 

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 as part of our wider corporate responsibility 
effort.    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:

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 Eastern Europe 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.  Any prolonged reduction 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 drilling activity since customers’ expectations of longer-term future commodity prices typically drive demand for our rigs.  The 
current commodity pricing environment has had a negative impact on demand for our services, and it could worsen.  Since December 31, 
2014, the price of crude oil as reported on the New York Mercantile Exchange has declined by approximately 50 percent.  Consequently, 
customers have delayed or cancelled 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 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.  We cannot predict when or if any idled or stacked rigs will return to service. 

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, growth in 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.  Presently, there are numerous recently constructed high-specification 
floaters and other drilling units capable of competing with our rigs that have entered the global market, and there are more that are under 
construction.  The entry into service of these new units has increased and will  continue to increase supply.  The increased supply has 

AR-10 

contributed  to  and  may  continue  to  contribute  to  a  reduction  in  dayrates  as  rigs  are  absorbed  into  the  active  fleet  and  has  led  to 
accelerated stacking of the existing fleet. 

Two of  our  six ultra-deepwater  drillships  and  our  five high-specification  jackups  currently  under  construction,  have  not  been 
contracted for work.  Combined with the rapid 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 
increase in construction of new units would likely exacerbate the negative impact of increased supply on dayrates and utilization rates.  
Additionally, lower market dayrates and intense price competition may drive customers to demand renegotiation of existing contracts to 
lower dayrates in exchange for longer contract terms.  In an over-supplied 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. 

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.    During  the  year 
ended  December 31,  2015,  our  customers  early  terminated  or  cancelled  contracts  for  Discoverer Americas,  Polar Pioneer,  Sedco 714, 
Sedco Energy and Transocean Spitsbergen, and these rigs currently remain idle.  Subsequent to December 31, 2015, we received notices 
of  early  termination  or  cancellation  of  drilling  contracts  for  Deepwater Champion,  Deepwater Millennium,  Discoverer Deep Seas, 
GSF Constellation II,  GSF Development Driller I  and  Transocean John Shaw.    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, which may have a material adverse impact on our 

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

At  February 11,  2016,  the  contract  backlog  associated  with  our  continuing  operations  was  approximately  $15.5 billion.    This 
amount represents the firm term of the drilling contract multiplied by the contractual operating rate, which may be higher than the actual 
dayrate we receive or we may receive other dayrates included in the contract such as waiting on weather rate, repair rate, standby rate or 
force majeure rate.  The contractual operating dayrate may also be higher than the actual dayrate we 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:

breakdowns of equipment and other unforeseen engineering problems; 
work stoppages, including labor strikes; 
shortages of material and skilled labor; 
surveys by government and maritime authorities; 
periodic classification surveys; 
severe weather, strong ocean currents or harsh operating conditions; and  
force majeure events. 

In certain drilling contracts, the dayrate may be reduced to zero or result in customer credit against future dayrate if, for example, 
repairs extend beyond a stated period of time.  Our contract backlog includes signed drilling contracts and, 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 to lower levels for an extended period of time.  Liquidity issues and other market pressures could lead 
our customers to go into bankruptcy or could encourage our customers 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”).  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  or  are  terminated  or 
obtain  drilling  contracts  for  our  uncontracted  newbuilds,  which  could  adversely  affect  our  consolidated  statements  of 
operations. 

Our ability to renew expiring drilling contracts or obtain new drilling contracts will depend on the prevailing market conditions at 
the time.  If we are unable to obtain new drilling contracts in direct continuation with existing contracts or for our uncontracted newbuild 
units, or if new drilling contracts are entered into at dayrates substantially below the existing dayrates or on terms otherwise less favorable 
compared to existing contract terms, our revenues and profitability could be adversely affected. 

The  offshore  drilling  markets  in  which  we  compete  experience  fluctuations  in  the  demand  for  drilling  services.    A  number  of 
existing drilling contracts for our drilling rigs that are currently operating are scheduled to expire before December 31, 2017.  Seven of the 
units we currently have under construction as part of our newbuild program, two ultra-deepwater drillships and our five high-specification 
jackups are being constructed without customer drilling contracts.  We will attempt to secure drilling contracts for these units prior to their 
completion.  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.  In particular, if oil and natural gas prices remain low, as is currently the case, or it is expected that 
such prices will decrease in the future, at a time when we are seeking drilling contracts for our rigs, we may be unable to obtain drilling 
contracts at attractive dayrates or at all. 

(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,  each  of  which  could  negatively 
affect our financial condition, results of operations and cash flows. 

We  must  make  substantial  capital  and  operating  expenditures  to  maintain  our  fleet.    These  expenditures  could  increase  as  a 

result of changes in the following: 

(cid:131) 
(cid:131)

the cost of labor and materials; 
customer requirements; 
fleet size; 
the cost of replacement parts for existing drilling rigs; 
the geographic location of the drilling rigs; 
length of drilling contracts; 
governmental  regulations  and  maritime  self-regulatory  organization  and  technical  standards  relating  to  safety,  security  or  the 
environment; and 
industry standards. 

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.    In  addition,  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, in order to execute our growth plan, we may require additional capital in the future.  If we are unable to fund capital 
expenditures with our cash flow from operations or 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 statements of financial condition, results of operations and cash flows. 

(cid:131) 

The  recent  downgrades  in  our  credit  ratings  by  various  credit  rating  agencies  could  impact  our  access  to  capital  and 
materially adversely affect our business and financial condition. 

Certain  credit  rating  agencies  have  recently  downgraded  the  credit  ratings  of  our  non-credit  enhanced  senior  unsecured 
long-term debt (“Debt Rating”).  In February 2015, Moody’s Investors Service downgraded our Debt Rating to below investment grade and, 
in  October 2015,  further  downgraded  our  Debt Rating,  and  recently  announced  that  our  Debt  Rating  is  again  under  review  for  further 
downgrade.  In March 2015, Standard & Poor’s downgraded our Debt Rating to below investment grade and recently further downgraded 
our  Debt Rating  with  negative  outlook.    In  October 2015,  Fitch  Ratings  downgraded  our  Debt  Rating  to  below  investment  grade  and 
recently further downgraded our Debt Rating with negative outlook.

limit our ability to access debt markets, including for the purpose of refinancing our existing debt; 
cause us to refinance or issue debt 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 downgrades 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,  and  we  may  lose  the  ability  to  obtain  future  financing  and  suffer  competitive 

disadvantages. 

At  December 31,  2015  and  2014,  our  overall  debt  level  was  approximately  $8.5 billion  and  $10.1 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) 

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 unable to meet financial ratios or satisfy certain other conditions included in our bank credit agreements, which could result in our 
inability to meet requirements for borrowings under our bank credit agreements or a default under these agreements and trigger  cross 
default provisions in our other debt instruments; 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. 

(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 financial results. 

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,  2015,  our  most  significant 
customers were Chevron and Shell, accounting for approximately 14 percent and 10 percent, respectively, of our consolidated operating 
revenues  from  continuing  operations.    As  of  February 11,  2016,  the  customers  with  the  most  significant  aggregate  amount  of  contract 
backlog associated with our drilling contracts were Shell and Chevron, representing approximately 51 percent and 21 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, financial condition and results of 
operations. 

(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.  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. 

AR-13 

The world economy is currently facing a number of challenges.  An extended period of negative outlook for the world economy 
could  reduce  the  overall  demand  for  oil  and  natural  gas  and  for  our  services.    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.  Such changes could adversely affect 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 as 
portions  of  the  crew  may  be  required  to  prepare  rigs  for  stacking,  after  which  time  the  crew  members  are  assigned  to  active  rigs  or 
dismissed.  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 11,  2016,  we  had  six ultra-deepwater  floater  and  five high-specification  jackup  newbuild  rig  projects.    We  also 
have a variety of other more limited shipyard projects at any given time.  These shipyard projects are subject to the risks of delay or cost 
overruns inherent in any such construction project resulting from numerous factors, including the following:

shipyard availability, failures and difficulties; 
shortages of equipment, materials or skilled labor; 
unscheduled delays in the delivery of ordered materials and equipment; 
design and engineering problems, including those relating to the commissioning of newly designed equipment; 
latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions; 
unanticipated actual or purported change orders; 
disputes with shipyards and suppliers; 
failure or delay of third-party vendors or service providers; 
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.  Delays in the delivery of these units would result in delay in 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.    Shortages  in  materials,  manufacturing 
defects,  delays  in  the  delivery  of  necessary  spare  parts,  equipment  or  other  materials,  or  the  unavailability  of  ancillary  services  could 
negatively impact our future operations 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 combined response team to the Macondo well incident was unable to stem the flow of hydrocarbons from the well prior to 
the  sinking  of  Deepwater Horizon.    The  resulting  spill  of  hydrocarbons  was  the  most  extensive  in  U.S.  history.    Under  the 
Deepwater Horizon drilling contract and in accordance with our settlement agreement with the operator, BP agreed to indemnify us with 
respect to certain matters, and we agreed to indemnify BP with respect to certain matters (see “Part II. Item 8. Financial Statements and 
Supplementary Data—Notes to Consolidated Financial Statements—Note 14—Commitments and Contingencies—Macondo well incident 
commitments  and  contingencies—BP  Settlement  Agreement”).    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 

AR-14 

with our settlement with 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)  Our agreement with the U.S. Environmental Protection Agency may prohibit us from entering into, extending or engaging in 
certain business relationships.  In addition, if we do not comply with the terms of our agreement with the U.S. Environmental 
Protection Agency, we may be subject to suspension, debarment or statutory disqualification. 

On February 25, 2013, we and the U.S. Environmental Protection Agency (the “EPA”) entered into an administrative agreement 
(the “EPA Agreement”) related to the Macondo well incident, which has a five-year term.  In the EPA Agreement, we agreed to, among 
other things, continue the implementation of certain programs and systems; comply with certain employment and contracting procedures; 
engage independent compliance auditors and a process safety consultant; and give reports and notices with respect to various matters.  
Subject to certain exceptions, the EPA Agreement prohibits us from entering into, extending or engaging in certain business relationships 
with individuals or entities that are debarred, suspended, proposed for debarment or similarly restricted.  In addition, if we fail to comply 
with  the  terms  of  the  EPA Agreement,  we  may  be  subject  to  suspension,  debarment  or  statutory  disqualification.    See  “Part II.  Item 8. 
to  Consolidated  Financial  Statements—Note 14—Commitments  and 
Financial  Statements  and  Supplementary  Data—Notes 
Contingencies—Macondo well incident commitments and contingencies—EPA Agreement.” 

(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. 

New  governmental  safety  and  environmental  requirements  applicable  to  both  deepwater  and  shallow  water  operations  have 
been adopted for drilling in the U.S. Gulf of Mexico following the Macondo well incident.  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  new  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 
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  requirements  applicable  to  us  under  the 
Consent Decree and the EPA Agreement cover safety, environmental, reporting, operational and other matters and are in addition to the 
regulations  applicable  to  other  industry  participants  and  may  require  additional  agreements  and  corporate  compliance  resources  that, 
together  with  our  cooperation  guilty  plea  agreement  by  and  among  the  DOJ  and  certain  of  our  affiliates  (the  “Plea Agreement”),  could 
cause us to incur additional costs and liabilities. 

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.  We are 
unable to predict the impact that the continuing effects of the enhanced regulations will have on our operations. 

(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  (“GHGs”),  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. 

AR-15 

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 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  has  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.  In addition, our Consent Decree, the EPA Agreement and probation arising out of 
our Plea Agreement add to these regulations, requirements and liabilities.  Our guilty plea to negligently discharging oil into the U.S. Gulf of 
Mexico  in  connection  with  the  Macondo well  incident  caused  us  to  incur  liabilities  under  the  environmental  laws  relating  to  the 
Macondo well incident.  We may be subject to additional liabilities and penalties.

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  foreign  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 foreign 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 

AR-16 

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 foreign 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 hurt 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. 

(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 area are 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 

AR-17 

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 unless contractually required, 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)  Recent developments in Swiss corporate governance may affect our ability to attract and retain top executives. 

On  January 1,  2014,  subject  to  certain  transitional  provisions,  the  Swiss  Federal  Council  Ordinance  Against  Excessive 
Compensation  at  Public  Companies  (the  “Ordinance”)  became  effective.    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  the  2014 annual  general  meeting,  our  shareholders  approved 
amendments to our articles of association that implement the requirements of the Ordinance, and at our 2015 annual general meeting our 
shareholders for the first time approved in a binding “say on pay” vote the compensation of members of our executive management and 
board  of  directors.    At  the  2016 annual  general  meeting,  our  shareholders  will  be  required  to  approve  the  maximum  aggregate 
compensation of (1) our board of directors for the period between the 2016 annual general meeting and the 2017 annual general meeting 
and (2) our executive management team for the year ending December 31, 2017.  The Ordinance further provides for criminal penalties 
against directors and members of executive management in case of noncompliance with certain of its requirements.  The Ordinance may 
negatively affect our ability to attract and retain executive management and members of our board of directors. 

(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 
in 
acquisitions,  divestitures  and  other  business  combinations,  such  as  our 
Transocean Partners LLC, 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: 

initial  public  offering  of  and 

investment 

(cid:131)  We may be unable to realize the growth or investment opportunities, improvement of our financial position and other expected benefits by 

(cid:131) 

(cid:131) 

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; and 
The diversion of management and key employees' attention may detract from the our ability to increase revenues and minimize costs; 
Certain transactions may result in other unanticipated adverse consequences. 

(cid:131) 
(cid:131) 
(cid:131)  We may be required to guarantee certain obligations or provide funding to Transocean Partners through a $300 million revolving  credit 
facility  between  us  and  Transocean Partners  which  may  impact  our  liquidity  of  ability  to  borrow  the  full  amount  of  capacity  under  our 
existing credit facilities. 

(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. 

AR-18 

(cid:131)  Significant part or equipment shortages, supplier capacity constraints, supplier production disruptions, supplier quality and 
sourcing  issues  or  price  increases  could  increase  our  operating  costs,  decrease  our  revenues  and  adversely  impact  our 
operations. 

Our  reliance  on  third-party  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.  Recent industry developments have reduced the 
number of available suppliers.  A disruption in the deliveries from such third-party suppliers, manufacturers or service providers, capacity 
constraints, production disruptions, price increases, quality control issues, recalls or other decreased availability of parts and equipment 
could adversely affect our ability to meet our commitments to customers, adversely impact our operations and revenues or increase our 
operating costs. 

(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 30 percent of our total workforce, working primarily in Angola, the U.K., Nigeria, Norway, Australia and Brazil are 
represented by, and some of our contracted labor work under, 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  apply  to  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 foreign 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 also 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, commonly referred to as greenhouse gases (“GHGs”) 
and  including  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  GHG  emissions,  in  particular  emissions  from  fossil  fuels,  is 
attracting increasing attention worldwide. 

Legislation  to  regulate  emissions  of  GHGs  has  been  introduced  in  the  U.S.  Congress.    Some  of  the  proposals  would  require 
industries to meet stringent new standards that may require substantial reductions in carbon emissions.  Such reductions could be costly 
and  difficult  to  implement.    In  addition,  efforts  have  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  the  U.S.,  the  EPA  has  undertaken  efforts  to  regulate  GHG  emissions  and  has  finalized  motor  vehicle  GHG  emissions 
standards,  the  effect  of  which  could  reduce  demand  for  motor  fuels  refined  from  crude  oil,  and  has  also  issued  a  final  rule  to  address 
permitting of GHG emissions from stationary sources under the Clean Air Act’s Prevention of Significant Deterioration and Title V programs 
commencing when the motor vehicle standards took effect on January 2, 2011.  To the extent that our operations are subject to the EPA’s 
GHG regulations, we may face increased capital and operating costs. 

AR-19 

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  GHGs  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  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.  Further, our patent for dual-activity technology has 
been successfully challenged in certain jurisdictions, and we have been accused of infringing other patents.  Other subsidiaries are subject 
to litigation relating to environmental damage.  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, policies may not be 
located,  and  liabilities  associated  with  the  Macondo well  incident  may  exhaust  some  or  all  of  the  insurance  available  to  cover  certain 
claims.    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.  We are also subject to a number of significant tax disputes, including trials on civil charges that commenced in Norway in 
2012.  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. 

(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. 

AR-20 

 
 
Other risks 

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

At December 31, 2015, the carrying amount of our property and equipment was $20.8 billion, representing 79 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, 2015, we recognized an aggregate loss of $1,175 million associated with the impairment of our 
deepwater  floater  and  midwater  floater  asset  groups.    In  the  year  ended  December 31,  2014,  we  recognized  a  loss  of  $788 million 
associated with the impairment of our deepwater floater asset group.  Future expectations of lower dayrates or rig utilization  rates or a 
significant change to the composition of one or more of our asset groups 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. 

In  the  U.S.,  tax  legislative  proposals  intending  to  eliminate  some  perceived  tax  advantages  of  companies  that  have  legal 
domiciles outside the U.S., but have certain U.S. connections, have repeatedly been introduced in the U.S. Congress.  Recent examples 
include,  but  are  not  limited  to,  legislative  proposals  that  would  broaden  the  circumstances  in  which  a  non-U.S.  company  would  be 
considered a U.S. resident, including the use of “management and control” provisions to determine corporate residency, and proposals that 
could override certain tax treaties and limit treaty benefits on certain payments  by U.S. subsidiaries to non-U.S. affiliates.   Additionally, 
members  of  the  U.S.  Congress  have  repeatedly  introduced  proposals  which  would  disallow  any  deduction  for  otherwise  tax  deductible 
payments relating to any incident resulting in the discharge of oil into navigable waters, such as the Macondo well incident.  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. 

In Switzerland, tax legislative proposals  intending to abolish certain cantonal tax privileges to the extent such provisions treat 
Swiss  and  non-Swiss  income  differently  as  well  as  implement  other  significant  changes  to  existing  tax  laws  and  practices  have  been 
raised.    These  proposals  are  in  response  to  certain  guidance  and  demands  from  both  the  European  Union  and  the  Organization  for 
Economic Co-operation and Development (the “OECD”).  These issues, plus other tax legislative matters, are expected to be considered 
by Switzerland during the next 12 months.  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. 

In December 2013, the U.K. Treasury released draft proposals that would cap the amount a U.K.-based contractor would be able 
to claim as a deductible expense for charter payments made to related companies.  A ring fence was also proposed to ensure that the 
profits from activities in relation to the chartering of rigs from affiliates are not reduced by tax relief from any unconnected activities.  On 
July 17, 2014, the U.K. legislation received Royal Assent with retroactive application effective as of April 2014.  In December 2014, the 
U.K. Treasury released additional draft legislative proposals that would impose tax on certain aggressive tax planning techniques used by 
multinational entities to divert profits from the U.K.  The draft legislation would tax companies that had structured its operations to avoid a 
permanent establishment in the U.K. and as a result of the structure the U.K. tax liability was reduced by 20 percent.  The draft legislation 
would also apply to transactions lacking economic substance that occur between common controlled entities and the resulting transaction 
reduces the U.K. tax liability by 20 percent.  The draft legislation would apply a 25 percent tax on companies that utilized theses aggressive 
techniques.  The legislation became effective on April 1, 2015. 

In  December 2014,  a  special  commission 

  These 
recommendations included consideration of a decrease in the corporate income tax rate, as well as a cap on the tax deduction for charter 
payments made to related companies and a withholding tax on certain charter payments to related companies.  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.

tax  reform 

Similarly, the OECD issued an action plan in July 2013 that called for member states to take action to prevent “base erosion and 
profit shifting” in situations where payments are made between affiliates from a jurisdiction with high tax rates to a jurisdiction with lower tax 
rates.  A number of specific tax reform changes were proposed and publicly debated.  In October 2015, the OECD issued its final package 

AR-21 

of measures.  Some of these proposals may 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.  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 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. 

(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. 

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., Norway or Brazil, 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 recent  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 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 15 percent tax rate on “qualified dividend income,” which applies to dividends paid to non-corporate shareholders prior to 2011, 

AR-22 

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. 

Our ability to benefit from our deferred tax assets depends on us having sufficient future earnings to utilize our net operating loss 
carryforwards before they expire.  We have established a valuation allowance against the future tax benefit for a number of our non-U.S. 
net  operating  loss  carryforwards,  and  we  could  be  required  to  record  an  additional  valuation  allowance  against  our  non-U.S.  or  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 carryforwards are subject to review and potential disallowance upon audit by the tax 
authorities of the jurisdictions where the net operating losses are incurred. 

(cid:131)  Our status as a Swiss corporation may limit our flexibility with respect to certain aspects of capital management and may 
cause us to 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.  As a matter of Swiss law, 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.    At  our  2014 annual  general 
meeting, our shareholders approved an authorized share capital, which will expire on May 16, 2016.  Our current authorized share capital 
is limited to approximately six percent of our registered share capital.  Unless our shareholders approve a new authorized share capital at 
our 2016 annual general meeting, we will generally need to obtain shareholder  approval in the  event we need to raise  common equity 
capital.    Additionally,  subject  to  specified  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  present  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,  and  since  January 1,  2011,  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.  On February 12, 2010, our board of directors 
authorized  our  management  to  implement  the  share  repurchase  program.    On  May 24,  2013,  we  received  approval  from  the  Swiss 
authorities  for  the  continuation  of  the  share  repurchase  program  for  an  additional  three-year  repurchase  period  through  May 23,  2016.  
Upon the delisting of our shares from the SIX becoming effective, which we expect to occur on March 31, 2016, the authorization of any 
new share repurchase program and the continuation of the share repurchase program approved at the 2009 annual general meeting will 
no longer be subject to approval requirements from Swiss authorities.  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 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.

(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 
provisions, among other things:

maximum  two-year  period,  which  under  the  current  authorized  share  capital  of  the  Company  will  expire  on  May 16,  2016,  to  issue  a 
specified number of shares, which under the current authorized share capital of the Company is approximately six 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 45 percent  of the 
share capital currently registered in the commercial register 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.

Shareholder Matters 

Shareholder distributions 

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.  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, shareholders approved  the 
cancellation of the third and fourth installments of the distribution at our extraordinary general meeting. 

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 June 18, September 17 and December 17, 2014, we paid the first three installments in 
the  aggregate  amount  of  $816 million  to  shareholders  of  record  as  of  May 30,  August 22  and  November 14,  2014,  respectively.    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. 

In May 2013, 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  $2.24 per  outstanding  share,  payable  in  four quarterly  installments  of  $0.56 per 
outstanding share, subject to certain limitations.  On June 19, September 18 and December 18, 2013, we paid the first three installments, 
in the aggregate amount of $606 million, to shareholders of record as of May 31, August 23 and November 15, 2013, respectively.  On 
March 19, 2014, we paid the final installment in the aggregate amount of $202 million to shareholders of record as of February 21, 2014. 

We do not pay the distribution of qualifying additional paid-in capital with respect to our shares held in treasury or held by our 
subsidiary.  Any future declaration and payment of any cash distributions will (1) depend on our results of operations, financial condition, 
cash requirements and other relevant factors, (2) be subject to shareholder approval, (3) be subject to restrictions contained in our credit 
facilities  and  other  debt  covenants,  (4) be  affected  by  our  plans  regarding  share  repurchases  or  noncash  shareholder  distributions  and 
(5) be subject to restrictions imposed by Swiss law, including the requirement that sufficient distributable profits from the previous year or 
freely distributable reserves must exist.

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 relation to a reduction of par value are exempt from Swiss withholding tax.  Since 
January 1, 2011, distributions to shareholders out of qualifying additional paid-in capital for Swiss statutory purposes are also exempt from 
the  Swiss  withholding  tax.    On  December 31,  2015,  the  aggregate  amount  of  par  value  of  our  outstanding  shares  was  CHF 5.6 billion, 
equivalent to $5.6 billion, and the aggregate amount of qualifying additional paid-in capital of our outstanding shares was CHF 8.9 billion, 
equivalent to $8.9 billion, at an exchange rate of $1.00 to CHF 1.00 on December 31, 2015.  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.  The procedures for claiming treaty refunds, and the time frame required for obtaining a refund, may differ from country to country. 

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

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

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 needs to be filled out in triplicate, with each copy duly completed and signed before a notary public in the U.S.  
Evidence that the withholding tax was withheld at the source must also be included. 

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

AR-29 

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. 

We expect the delisting of our shares on the SIX to become effective on March 31, 2016.  Thereafter, 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.

(a)  Total number of shares purchased in the fourth quarter of 2015 consists of 1,757 shares withheld by us through a broker arrangement and limited to 
statutory tax in satisfaction of withholding taxes due upon the vesting of restricted shares granted to our employees under our Long-Term Incentive 
Plan. 
In May 2009, at the annual general meeting of Transocean Ltd., 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, which is equivalent to approximately 
$3.5 billion at an exchange rate as of December 31, 2015 of USD 1.00 to CHF 1.00.  On February 12, 2010, our board of directors authorized our 
management to implement the share repurchase program.  On May 24, 2013, we received approval from the Swiss authorities for the continuation of 
the share repurchase program for an additional three-year repurchase period through May 23, 2016.  Upon the delisting of our shares from the SIX 
becoming effective, which we expect to occur on March 31, 2016, the authorization of any new share repurchase program and the continuation of 
the  share  repurchase  program  approved  at  the  2009 annual  general  meeting  will  no  longer  be  subject  to  approval  requirements  from  Swiss 
authorities.  We may decide, based upon our ongoing capital requirements, our program of distributions to our shareholders, 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, and consequently, repurchase fewer or no additional shares under this program.  Decisions regarding the amount, if any, and 
timing of any share repurchases would be made from time to time based upon these factors.  Through December 31, 2015, we have repurchased a 
total of 2,863,267 of our shares under this share repurchase program at a total cost of $240 million, equivalent to an average  cost of $83.74 per 
share.  On October 29, 2015, shareholders at our extraordinary general meeting approved the cancellation of all shares that have been repurchased 
to  date  under  our  share  repurchase  program.    The  cancellation  of  our  shares  held  in  treasury  became  effective  as  of  January 7,  2016  upon 
registration of the cancellation in the commercial register.  See “—Sources and uses of liquidity.”

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 16,  2016,  we  owned  or  had  partial  ownership  interests  in  and  operated  61 mobile  offshore  drilling  units,  including 
28 ultra-deepwater  floaters,  seven harsh  environment  floaters,  five deepwater  floaters,  11 midwater  floaters,  and  10 high-specification 
jackups.  At February 16, 2016, we also had six ultra-deepwater drillships and five high-specification jackups 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  deepwater  and  harsh  environment  drilling  services.    We  believe  our 
drilling fleet is one of the most versatile fleets in the world, consisting of floaters and high-specification jackups 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. 

On  August 5,  2014,  we  completed  an  initial  public  offering  to  sell  a  noncontrolling  interest  in  Transocean Partners LLC 
(“Transocean Partners”),  a  Marshall  Islands  limited  liability  company,  which  was  formed  on  February 6,  2014,  by  Transocean Partners 
Holdings Limited,  a  Cayman  Islands  company  and  our  wholly  owned  subsidiary,  to  own,  operate  and  acquire  modern,  technologically 
advanced offshore drilling rigs.  See Notes to Consolidated Financial Statements—Note 15—Noncontrolling Interest. 

In  February 2014,  in  connection  with  our  efforts  to  discontinue  non-strategic  operations,  we  completed  the  sale  of 
Applied Drilling Technology International Limited (“ADTI”), a U.K. company, which performs drilling management services in the North Sea.

Significant Events 

Macondo well  incident  litigation  and  settlements  and  insurance  recoveries—On  May 20,  2015,  we  entered  into  a 
confidential  settlement  agreement  with  BP  to  settle  various  disputes  remaining  between  the  parties  with  respect  to  the  Macondo well 
incident  (the  “BP Settlement  Agreement”).    On  May 29,  2015,  together  with  the  Plaintiff’s  Steering  Committee  (the  “PSC”),  we  filed  a 
settlement agreement (the “PSC Settlement Agreement”) with the U.S. District Court for the Eastern District of Louisiana (the “MDL Court”) 
through  which  we  have  agreed  to  pay,  subject  to  the  MDL Court  approval,  a  total  of  $212 million,  plus  up  to  $25 million  for  partial 
reimbursement  of  attorneys’  fees.    On  October 13,  2015,  we  finalized  a  settlement  agreement  with  the  States  of  Alabama,  Florida, 
Louisiana, Mississippi, and Texas (collectively, the “States”), pursuant to which the States agreed to release all of their claims against us 
arising  from  the  Macondo well  incident.    In  the  year  ended  December 31,  2015,  in  connection  with  such  settlements,  we  recognized 
income of $788 million ($735 million, 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.  In the year ended December 31, 2015, we received cash proceeds of $538 million associated with recoveries from 
insurance,  we  received  cash  proceeds  of  $125 million  associated  with  the  partial  reimbursement  from  BP  for  previously  incurred  legal 
costs, we made a cash deposit of $212 million into an escrow account associated with the pending court approval of our settlement with 
the  PSC  and  we  made  an  aggregate  cash  payment  of  $35 million  to  the  States.    See  “—Operating  Results,”  “—Liquidity  and  Capital 
Resources—Sources and uses of liquidity” and “—Contingencies and Uncertainties—Macondo well incident.” 

Norway  tax  investigations  and  trial—In  January 2016,  the  Norwegian  authorities  formally  and  unconditionally  dropped  all 
criminal  charges  against  our  subsidiaries  and  the  two employees  of  our  former  external  advisors  and  our  former  external  Norwegian 
attorney.  As a result, no criminal charges remain outstanding for any of the previously reported Norway tax investigations or trials and all 
our  subsidiaries  and  external  advisors  have  been  fully  acquitted  of  all  criminal  charges.    See  “—Contingencies  and  Uncertainties—Tax 
matters.”

Debt  redemption  and  repurchases—On  July 30,  2015,  we  redeemed  the  aggregate  principal  amount  of  $893 million  of  the 
outstanding 4.95% Senior Notes with an aggregate cash payment of $904 million for the full redemption of the notes, and we recognized a 
loss of $10 million associated with the retirement of the debt.  During the year ended December 31, 2015, we made an aggregate cash 
payment  of  $468 million  and  recognized  an  aggregate  net  gain  of  $33 million  associated  with  the  open  market  repurchases  of  an 
aggregate  principal  amount  of  $503 million  of  certain  of  our  publicly  traded  debt  securities.    See  “—Liquidity  and  Capital  Resources—
Sources and uses of liquidity”. 

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.  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,  shareholders  at  our  extraordinary  general  meeting  approved  the  cancellation  of  the  third and 
fourth installments of the dividend. 

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 June 18, September 17 and December 17, 2014, we paid the first three installments in 
the aggregate amount of $816 million to shareholders of record as of May 30, August 22 and November 14, 2014.  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. 

In May 2013, 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 $2.24 per outstanding share, payable in four quarterly installments, subject  to certain 
limitations.    On  March 19,  2014,  we  paid  the  final  installment  in  the  aggregate  amount  of  $202 million  to  shareholders  of  record  as  of 
February 21, 2014. 

See “—Liquidity and Capital Resources—Sources and uses of liquidity.” 

Impairments  of  long-lived  assets—During  the  year  ended  December 31,  2015,  we  identified  indicators  that  our  deepwater 
floater and midwater floater asset groups may not be recoverable.  As a result of our impairment testing, in the year ended December 31, 
2015, we recognized a loss of $1.2 billion ($1.1 billion, net of tax) associated with the impairment of these held and used assets.  See “—
Operating Results” and Notes to Consolidated Financial Statements—Note 5—Impairments. 

In the year ended December 31, 2015, we recognized an aggregate loss of $692 million ($578 million, 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 the midwater floaters GSF Aleutian Key, GSF Arctic III, 
GSF Grand Banks, GSF Rig 135, Transocean Amirante  and Transocean Legend along with related equipment, which were classified as 
assets  held  for  sale  at  the  time  of  the  impairment.    See  “—Operating  Results”,  “—Liquidity  and  Capital  Resources—Drilling  fleet”  and 
Notes to Consolidated Financial Statements—Note 5—Impairments. 

Drilling  contract  terminations—As  a  result  of  recent  market  conditions,  we  have  observed  an  unprecedented  level  of  early 
drilling  contract  terminations  in  the  contract  drilling  industry.    In  the  year  ended  December 31,  2015,  we  recognized  revenues  of 
$505 million  and  received  aggregate  cash  proceeds  of  $400 million  associated  with  early  terminated  or  cancelled  drilling  contracts  for 
Discoverer Americas,  Polar Pioneer,  Sedco 714,  Sedco Energy  and  Transocean Spitsbergen.    Subsequent  to  December 31,  2015,  we 
received  notices  of  early 
for  Deepwater Champion,  Deepwater Millennium, 
Discoverer Deep Seas,  GSF Constellation II,  GSF Development Driller I  and  Transocean John Shaw.    See  “—Outlook,”  “—Operating 
Results” and “—Liquidity and Capital Resources—Sources and uses of cash.”

Markets for our shares—Our shares are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “RIG” and 
on the SIX Swiss Exchange (“SIX”) under the symbol “RIGN.”  On November 23, 2015, we announced our intent to delist our shares from 
the SIX.  On December 17, 2015 we announced that the SIX listing authorities approved our application to delist our shares, and such 
delisting is expected to become effective on March 31, 2016, with the last trading day scheduled to be March 30, 2016.  Our shares will 
continue to be listed and traded on the NYSE. 

Par value reduction—On October 29, 2015, shareholders at our extraordinary general meeting 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 the par value became effective as 
of  January 7,  2016  upon  registration  in  the  commercial  register.    See  Notes  to  Consolidated  Financial  Statements—Note 16—

Outlook 

Drilling market—Although our long-term view of the offshore drilling market remains positive, particularly for high-specification 
assets,  we  expect  the  near  to  medium  term  to  be  especially  challenging.    The  sustained  weak  commodity  pricing,  coupled  with  our 
customers’ focus on reducing costs, spending within their cash flow and maintaining capital allocation policies are resulting in the delay of 
many exploration and development programs.  Oil and natural gas prices do not currently support sustained demand for drilling rigs across 
all asset classes and regions.  As a result of this reduced demand, we have seen a sharp decline in the execution of drilling contracts for 
the global offshore drilling fleet and an increase in the early termination or cancellation of drilling contracts.  We currently expect very few 
drilling  contracts  to  be  awarded  in  2016,  exacerbating  the  excess  rig  capacity  and  placing  continued  downward  pressure  on  dayrates.  
During the year ended December 31, 2015, our customers early terminated or cancelled contracts for Discoverer Americas, Polar Pioneer, 
Sedco 714,  Sedco Energy  and  Transocean Spitsbergen.    Then,  subsequent  to  December 31,  2015,  we  received  notices  of  early 
for  Deepwater Champion,  Deepwater Millennium,  Discoverer Deep Seas, 
termination  or  cancellation  of  drilling  contracts 
GSF Constellation II, GSF Development Driller I and Transocean John Shaw.  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, 2015 and 
2014, we sold 17 and two drilling units, respectively, for scrap value, and at December 31, 2015, we had five additional rigs classified as 
held for sale for scrap value.  As of February 11, 2016, our contract backlog was $15.5 billion compared to $16.9 billion as of October 26, 
2015. 

Fleet status—We present the availability of our rigs in terms of the uncommitted fleet rate.  The uncommitted fleet rate is defined 
as  the  number  of  uncommitted  days  divided  by  the  total  number  of  rig  calendar  days  in  the  measurement  period,  expressed  as  a 
percentage.  An uncommitted day is defined as a calendar day during which a rig is idle or stacked, is not contracted to a customer and is 
not committed to a shipyard.  The uncommitted fleet rates exclude the effect of priced options. 

As of February 11, 2016, uncommitted fleet rates for each of the five years in the period ending December 31, 2020 were as 

follows:

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  maximum  contractual  operating  dayrate  to  be  earned  per  operating  day  in  the  measurement  period.    An 
operating day is defined as a day for which a rig is contracted to earn a dayrate during the firm contract period after commencement of 
operations. 

The  contract  backlog  represents  the  maximum  contract  drilling  revenues  that  can  be  earned  considering  the  contractual 
operating dayrate in effect during the firm contract period and represents the basis for the maximum revenues in our revenue efficiency 
measurement.  To determine maximum revenues for purposes of calculating revenue efficiency, however, we include the revenues earned 
for mobilization, demobilization and contract preparation, other incentive provisions or cost escalation provisions which are excluded from 
the amounts presented for contract backlog. 

The contract backlog for our fleet was as follows:

Our contract backlog includes only firm commitments, which are represented by signed drilling contracts or, in some cases, by 
other definitive agreements awaiting contract execution.  Our contract backlog includes amounts associated with our newbuild units that 
are  currently  under  construction.    The  contractual  operating  dayrate  may  be  higher  than  the  actual  dayrate  we ultimately  receive  or  an 
alternative contractual dayrate, such as a waiting-on-weather rate, repair rate, standby rate or force majeure rate, may apply under certain 
circumstances.  The contractual operating dayrate may also be higher than the actual dayrate we ultimately receive because of a number 
of factors, including rig downtime or suspension of operations.  In certain contracts, the dayrate may be reduced to zero if, for example, 
repairs extend beyond a stated period of time. 

At February 11, 2016, the contract backlog and average contractual dayrates for our fleet were as follows:

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 or classification as discontinued operations.

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. 

For the year ended December 31, 2015, our rig utilization for deepwater floaters and midwater floaters increased as a result of 

removing stacked and idled rigs from our drilling fleet.

Operating revenues—Contract drilling revenues decreased for the year ended December 31, 2015 compared to the year ended 
December 31, 2014 primarily due to the following: (a) approximately $1.7 billion of decreased revenues resulting from a greater number of 
rigs  idle  or  stacked,  (b) approximately  $945 million  of  decreased  revenues  resulting  from  rigs  sold  or  classified  as  held  for  sale  and 
(c) approximately  $120 million  of  decreased  revenues  resulting  from  lower  dayrates.    These  decreases  were  partially  offset  by  the 
following:  (a) approximately  $280 million  of  increased  revenues  associated  with  our  two newbuild  ultra-deepwater  drillships  that 
commenced operations in the year ended December 31, 2014, (b) approximately $240 million of increased revenues resulting from fewer 
shipyard and mobilization days for the active fleet, (c) approximately $105 million of increased revenues resulting from improved revenue 
efficiency and (d) approximately $90 million of increased revenues resulting from demobilization fees. 

Other revenues increased for the year ended December 31, 2015 compared to the year ended December 31, 2014, primarily 

due to $433 million of revenues for early termination or cancellation fees. 

Costs  and  expenses—Excluding  the  favorable  effect  of  $788 million  resulting  from  cost  reimbursements  from  settlements, 
recoveries  from  insurance  and  net  adjustments  to  contingent  liabilities  associated  with  the  Macondo well  incident,  operating  and 
maintenance expense decreased for the year ended December 31, 2015 compared to the year ended December 31, 2014 primarily due to 
the  following:  (a) approximately  $545 million  of  decreased  costs  and  expenses  resulting  from  rigs  sold  or  classified  as  held  for  sale, 
(b) approximately  $395 million  of  decreased  costs  and  expenses  resulting  from  cost  reductions  for  our  idle  or  stacked  rigs, 
(c) approximately $345 million of decreased costs and expenses resulting fewer shipyard and mobilization costs and reduced personnel 
expenses  associated  with  our  active  fleet  and  (d) approximately  $135 million  of  decreased  costs  and  expenses  resulting  from  reduced 
onshore costs.  These decreases were partially offset by approximately $70 million of increased costs and expenses associated with our 
two newbuild ultra-deepwater drillships that commenced operations in the year ended December 31, 2014. 

Depreciation  expense  decreased  for  the  year  ended  December 31,  2015  compared  to  the  year  ended  December 31,  2014 
primarily due to the following: (a) approximately $198 million of decreased depreciation resulting from rigs sold or classified as held for sale 
and (b) approximately $94 million of decreased depreciation resulting from the impairment of our deepwater floater and midwater floater 
asset groups.  These decreases were partially offset by the following: (a) approximately $51 million of increased depreciation resulting from 
the reduction of the salvage values for certain drilling units and (b) approximately $30 million of increased depreciation resulting from our 
two newbuild  ultra-deepwater  drillships  that  commenced  operations  in  the  year  ended  December 31,  2014  and  (c) approximately 
$35 million of increased depreciation resulting from our completion of other construction projects.

General  and  administrative  expense  decreased  for  the  year  ended  December 31,  2015  compared  to  the  year  ended 
December 31, 2014 primarily due to due to the following: (a) approximately $21 million of reduced personnel costs and (b) approximately 
$13 million of reduced legal and professional fees. 

Losses on impairments and disposals—In the year ended December 31, 2015, we recognized a loss on impairment related to 
the  following:  (a) a  loss  of  $507 million  associated  with  the  impairment  of  our  deepwater  floater  asset  group,  (b) a  loss  of  $668 million 
associated  with  the  impairment  of  our  midwater  floater  asset  group  and  (c) an  aggregate  loss  of  $692 million  associated  with  the 
impairment  of  certain  assets  classified  as  held  for  sale.    In  the  year  ended  December 31,  2014,  we  recognized  a  loss  on  impairment 
related to the following: (a) a loss of $3.0 billion associated with the full impairment of the carrying amount of our goodwill, (b) a loss of 
$788 million associated with the impairment of our deepwater floater asset group and (c) an aggregate loss of $268 million associated with 
the impairment of certain assets classified as held for sale. 

In  the  year  ended  December 31,  2015,  we  recognized  an  aggregate  net  gain  of  $14 million  associated  with  the  sale  of 
two ultra-deepwater  floaters,  six deepwater  floaters  and  nine midwater  floaters,  along  with  related  equipment.    In  the  year  ended 
December 31, 2014, we recognized an aggregate net loss of $1 million associated with the sale of a deepwater floater, a midwater floater 
and  two high-specification  jackups  along  with  related  equipment.    In  the  years ended  December 31,  2015  and 2014,  we recognized  an 
aggregate net loss of $42 million and $25 million, respectively, associated with the disposal of assets unrelated to rig sales. 

Other income and expense—In the year ended December 31, 2015, we recognized other income, net, primarily related to the 
following:  (a) a  gain  of  $35 million  associated  with  income  from  license  fees  and  royalties  for  our  dual-activity  patent  and  (b) a  gain  of 
$23 million  associated  with  the  early  retirement  of  debt,  including  the  redemption  of  the  4.95% Senior Notes  due  November 2015  (the 
“4.95% Senior Notes”) and repurchases of other public debt in the open market.  In the year ended December 31, 2014, we recognized 
other income, net primarily related to the following: (a) a gain of $18 million associated with currency exchange, (b) a gain of $7 million 
associated with the prepayment of certain notes receivable, (c) a gain of $7 million associated with settlement of litigation related to our 
dual-activity patent, partially offset by (d) an aggregate loss of $13 million associated with the early retirement of debt, including the partial 
redemption of the 4.95% Senior Notes and the termination of our former three-year secured revolving credit facility. 

Income tax expense—We operate internationally and provide for income taxes based on the tax laws and rates in the countries 
in  which  we  operate  and  earn  income.    For  the  years  ended  December 31,  2015  and  2014,  the  annual  effective  tax  rates  were 
16.4 percent  and  18.7 percent,  respectively,  based  on  income  from  continuing  operations  before  income  taxes,  after  excluding  certain 
items, such as losses on impairment, and gains and losses on certain asset disposals.  During the year ended December 31, 2015, our 
annual  effective  tax  rate  decreased  due  to  changes  in  the  relative  blend  of  income  from  operations  among  certain  jurisdictions  and 
changes in the jurisdictional and operating structure for certain rigs, which had an effect on our deferred tax assets.  This decrease was 
partially offset by an increase from changes in currency exchange rates.  We consider the tax effect, if any, of the excluded items as well 
as settlements of prior year tax liabilities and changes in prior year tax estimates to be discrete period tax expenses or benefits.  For the 
year  ended  December 31,  2015  and  2014,  the  effect  of  the  various  discrete  period  tax  items  was  a  net  tax  benefit  of  $35 million  and 
$138 million, respectively.  For the year ended December 31, 2015 and 2014, these discrete tax items, coupled with the excluded income 
and  expense  items  noted  above,  resulted  in  effective  tax  rates  of  20.0 percent  and  (8.1) percent,  respectively,  based  on  income  from 
continuing operations before income taxes. 

The  relationship  between  our  provision  for  or  benefit  from  income  taxes  and  our  income  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 versus income before taxes, (c) rig movements between taxing jurisdictions and 
(d) our rig operating structures.  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.    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 annual effective tax rate 
calculation for the year ended December 31, 2015, 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, India, Nigeria, Indonesia and the 
Republic of Congo.  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, the U.K., Switzerland, Brazil 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, 2014 compared to the year ended 
December 31, 2013 primarily due to the following: (a) approximately $500 million of decreased revenues resulting from a greater number 
of  idle  rigs,  (b) approximately  $245 million  of  decreased  revenues  resulting  from  rigs  that  were  sold  or  classified  as  held  for  sale  and 
(c) approximately $210 million of decreased revenues resulting from increased time dedicated to mobilization between contracts, shipyard 
projects and rig certifications.  These decreases were partially offset by the following: (a) approximately $290 million of increased revenues 
resulting  from  improved  dayrates,  (b) approximately  $285 million  of  increased  revenues  resulting  from  improved  revenue  efficiency  and 
(c) approximately  $265 million  of  increased  revenues  associated  with  our  three newbuild  high-specification  jackups  that  commenced 
operations during the year ended December 31, 2013 and our two newbuild ultra-deepwater drillships that commenced operations in the 
year ended December 31, 2014. 

Other revenues increased for the year ended December 31, 2014 compared to the year ended December 31, 2013, primarily 

due to increased revenues associated with reimbursable items. 

Costs and expenses—Operating and maintenance expense decreased for the year ended December 31, 2014 compared to the 
year ended December 31, 2013 primarily due to the following: (a) approximately $195 million of decreased costs and expenses due to rigs 
that were sold or classified as held for sale in the year ended December 31, 2014, (b) approximately $190 million of decreased costs and 
expenses, net of insurance recoveries, associated with the Macondo well incident and (c) approximately $130 million of decreased costs 
and expenses associated with stacked and idle rigs.  These decreases were partially offset by approximately $70 million of increased costs 
and expenses due to our newbuild rigs placed in service. 

General  and  administrative  expense  decreased  for  the  year  ended  December 31,  2014  compared  to  the  year  ended 
December 31, 2013 primarily due to due to the following: (a) $24 million of decreased personnel costs primarily associated with reduced 
wages  and  salaries,  and  (b) $21 million  of  decreased  legal  and  professional  fees,  primarily  related  to  litigation  and  the  2013  proxy 
campaign. 

Losses on impairments and disposals—In the year ended December 31, 2014, we recognized a loss on impairment related to 
the following: (a) a loss of $3.0 billion associated with the full impairment of the carrying amount of our goodwill, (b) a loss of $788 million 
associated  with  the  impairment  of  the  deepwater floater  asset  group  and  (c) an  aggregate  loss  of  $268 million  associated  with  the 
impairment  of  certain  assets  classified  as  held  for  sale.    In  the  year  ended  December 31,  2013,  we  recognized  an  aggregate  loss  of 
$64 million  associated  with  the  impairment  of  certain  assets  classified  as  held  for  sale  and  a  loss  of  $17 million  associated  with  the 
impairment of certain corporate assets.

In  the  year  ended  December 31,  2014,  we  recognized  an  aggregate  net  loss  of  $1 million  associated  with  the  sale  of  a 
deepwater floater, a midwater floater and two high-specification jackups along with related equipment.  In the year ended December 31, 
2013, we recognized a net gain of $33 million associated with the sale of a deepwater floater along with related equipment.  In the years 
ended December 31, 2014 and 2013, we recognized an aggregate net loss of $25 million and $26 million, respectively, associated with the 
disposal of assets unrelated to rig sales. 

Other income and expense—Interest expense, net of amounts capitalized, decreased in the year ended December 31, 2014 
compared to the year ended December 31, 2013, primarily due to approximately $55 million of increased interest capitalization associated 
with  our  newbuild  construction  program  and  $34 million  of  decreased  interest  expense  associated  with  debt  repaid  in  the  year  ended 
December 31, 2014. 

In  the  year  ended  December 31,  2014,  we  recognized  other  income,  net,  primarily  related  to  the  following:  (a) a  gain  of 
$18 million  associated  with  currency  exchange,  (b) a  gain  of  $7 million  associated  with  the  prepayment  of  certain  notes  receivable  and 
(c) a gain of $7 million associated with settlement of litigation related to our dual-activity patent, partially offset by (d) an aggregate loss of 
$13 million  associated  with  the  early  retirement  of  debt,  including  the  partial  redemption  of  the  4.95% Senior  Notes  and  the  early 
termination of our former three-year secured revolving credit facility.  In the year ended December 31, 2013, we recognized other expense, 
net, primarily related to the following: (a) a loss of $11 million associated with currency exchange, (b) a loss of $10 million associated with 
the  sale  of  an  investment  in  preference  shares  and  (c) a  loss  of  $9 million  associated  with  the  early  termination  of  interest  rate  swaps 
designated as a cash flow hedge of borrowings under a former credit facility. 

Income tax expense—We operate internationally and provide for income taxes based on the tax laws and rates in the countries 
in  which  we  operate  and  earn  income.    For  the  years  ended  December 31,  2014  and  2013,  our  annual  effective  tax  rates  were 
18.7 percent  and  20.1 percent,  respectively,  based  on  income  from  continuing  operations  before  income  taxes,  after  excluding  certain 
items, such as expenses for litigation matters, losses on impairment, and gains and losses on certain asset disposals.  The tax effect, if 
any,  of  the  excluded  items  as  well  as  settlements  of  prior  year  tax  liabilities  and  changes  in  prior  year  tax  estimates  are  all  treated  as 
discrete period tax expenses or benefits.  For the years ended December 31, 2014 and 2013, the effect of the various discrete period tax 
items  was  a  net  tax  benefit  of  $138 million  and  $82 million,  respectively.    For  the  years  ended  December 31,  2014  and  2013,  these 
discrete tax items, together with the excluded income and expense items noted above, resulted in effective tax rates of (8.1) percent and 
15.6 percent,  respectively,  based  on  income  from  continuing  operations  before  income  tax  expense,  including  these  discrete  tax  items, 
together with the excluded income and expense items noted above. 

The  relationship  between  our  provision  for  or  benefit  from  income  taxes  and  our  income  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 versus income before taxes, (c) rig movements between taxing jurisdictions and 
(d) our rig operating structures.  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.    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.    In  the  year  ended  December 31,  2014 
compared to the year ended December 31, 2013, the annual effective tax rate decreased to 18.7 percent from 20.1 percent primarily due 
to changes in the blend of income that is taxed based on gross revenues versus income before taxes, the effect of higher income before 
income taxes offset by the impact of new U.K. legislation and the currency exchange effect of the weakened Norwegian krone relative to 
the U.S. dollar.  With respect to the annual effective tax rate calculation for the year ended December 31, 2014, 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, India, Nigeria, Indonesia and the Republic of Congo.  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, the U.K., Switzerland, Australia 
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. 

Liquidity and Capital Resources 

Sources and uses of cash 

At December 31, 2015, we had $2.3 billion in cash and cash equivalents.  At any given time, we may require a significant portion 
of our cash and cash equivalents for working capital and other needs related to the operation of our business.  At December 31, 2015, we 
estimate  the  amount  of  cash  required  for  these  purposes,  which  is  not  generally  available  to  us  for  other  uses,  was  approximately 
$1.3 billion.    We  expect  to  reduce  this  required  amount  to  approximately  $800 million  as  an  outcome  of  our  ongoing  organizational 
efficiency initiatives and in the event our industry stabilizes. 

AR-40 

In the year ended December 31, 2015, our primary sources of cash were our cash flows from operating activities, including cash 
proceeds from customers that executed early terminations or cancellations of drilling contracts and proceeds from insurance recoveries 
and litigation settlements; net proceeds from restricted cash investments and proceeds from asset disposals.  Our primary uses of cash 
were capital expenditures, primarily associated with our newbuild construction projects; repayments of debt; payments of installments to 
our shareholders for distributions of qualifying paid-in capital and payment of our Macondo well incident settlement obligations.

Net cash provided by operating activities increased primarily due to cash proceeds of $400 million from customers that executed 
early  terminations  or  cancellations  of  drilling  contracts  and  other  changes  in  working  capital,  including  (a) an  increase  of  $639 million 
associated  with  cash  proceeds  from  insurance  recoveries  related  to  the  Macondo well  incident  and  (b) a  decrease  of  $208 million 
associated with cash payments of scheduled installments for our Macondo well incident settlement obligations.  Partially offsetting these 
items  was  a  cash  deposit  of  $212 million  into  an  escrow  account  pending  court  approval  of  our  settlement  with  the  PSC  with  no 
comparable activity in the prior year.

Net  cash  used  in  investing  activities  increased  primarily  due  to  a  reduction  of  proceeds  from  disposal  of  assets  and  from 
repayment of loans and notes receivable.  Partially offsetting the increased use of cash was a decrease in capital expenditures associated 
with the timing of milestone payments for our major construction projects and other shipyard projects.

Net  cash  used  in  financing  activities  increased  primarily  due  to  (a) increased  cash  used  to  redeem  or  repurchase  debt  and 
(b) cash  proceeds  from  the  sale  of  noncontrolling  interest  in  Transocean Partners  with  no  comparable  activity  in  the  year  ended 
December 31, 2015.  Partially offsetting these items was a reduction in cash used to pay installments to our shareholders for distributions 
of qualifying additional paid-in capital.

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. 

In the years ended December 31, 2015 and 2014, we made capital expenditures and other capital additions, such as capitalized 
interest, of $2.0 billion and $2.2 billion, respectively, including $1.6 billion and $1.4 billion, respectively, for our major construction projects.  
For the year ending December 31, 2016, we expect total capital expenditures and other capital additions, such as capitalized interest, to be 
approximately $1.4 billion, including approximately $1.3 billion for our major construction projects.   

As  of  December 31,  2015,  the  historical  and  projected  capital  expenditures  and  other  capital  additions,  including  capitalized 

interest, for our ongoing major construction projects were as follows: 

Deepwater Thalassa (a) 
Deepwater Proteus (b) 
Deepwater Conqueror (c) 
Deepwater Pontus (d) 
Deepwater Poseidon (d) 
Transocean Cassiopeia (e)

(a)  The ultra-deepwater floater Deepwater Thalassa commenced operations in February 2016. 

(b)  Deepwater Proteus,  a  newbuild  ultra-deepwater  drillship,  was  delivered  from  the  shipyard  and  is  expected  to  commence  operations  in  the  second quarter  of  2016 

following completion of mobilization, sea trials, operational readiness testing and customer acceptance. 

(c)  Deepwater Conqueror,  a  newbuild  ultra-deepwater  drillship  under  construction  at  the  Daewoo  Shipbuilding  &  Marine  Engineering Co. Ltd.  shipyard  in  Korea,  is 

expected to commence operations in the fourth quarter of 2016. 

(d)  Deepwater Pontus  and  Deepwater Poseidon,  two  newbuild  ultra-deepwater  drillships  under  construction  at  the  Daewoo  Shipbuilding  &  Marine  Engineering Co. Ltd. 

shipyard in Korea, are expected to commence operations in the fourth quarter of 2017 and the first quarter of 2018, respectively. 

(e)  Transocean Cassiopeia,  Transocean Centaurus,  Transocean Cepheus,  Transocean Cetus  and  Transocean Circinus,  five Keppel  FELS  Super B  400 Bigfoot  class 
design  newbuild  high-specification  jackups  under  construction  at  Keppel FELS’  shipyard  in  Singapore  do  not  yet  have  drilling  contracts  and  are  expected  to  be 
delivered in the first quarter of 2018, the third quarter of 2018, the first quarter of 2019, the third quarter of 2019 and the first quarter of 2020, respectively. 

(f)  Our two unnamed dynamically positioned 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 2019 and the first quarter of 2020, respectively. 

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  new  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.  We 
also have available credit under the Five-Year Revolving Credit  Facility, as described below, and may utilize other commercial  bank or 
capital market financings.  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  year  ended 
December 31, 2015, we identified 22 such drilling units that we intend to sell or have sold for scrap value, including the ultra-deepwater 
floaters Deepwater Expedition and GSF Explorer, the deepwater floaters Deepwater Navigator, Discoverer Seven Seas, GSF Celtic Sea, 
Sedco 707,  Sedco 710,  Sovereign Explorer  and  Transocean Rather  and 
floaters  C. Kirk Rhein, Jr.,  Falcon 100, 
GSF Aleutian Key,  GSF Arctic I,  GSF Arctic III,  GSF Grand Banks,  GSF Rig 135,  J.W. McLean,  Sedco 601,  Sedco 700,  Sedneth 701,

with  related  equipment,  and  we  received  aggregate  net  cash  proceeds  of  $35 million.    During  the  year  ended  December 31,  2014,  we 
completed the sale of the deepwater floater Sedco 709, the midwater floater Sedco 703 and the high-specification jackups GSF Magellan 
and GSF Monitor, along with related equipment, and we received aggregate net cash proceeds of $185 million.

Sources and uses of liquidity 

Overview—We  expect  to  use  existing  cash  balances,  internally  generated  cash  flows,  borrowings  under  our  bank  credit 
agreements, proceeds from the disposal of assets or proceeds from the issuance of debt to fulfill anticipated obligations, such as capital 
expenditures, scheduled debt maturities or other payments, repayment of debt due within one year, payments of our Macondo well incident 
settlement obligations, working capital and other needs in our operations.  We may also consider establishing additional credit facilities 
under  bank  credit  agreements,  using  proceeds  from  additional  issuances  of  debt,  or  using  proceeds  from  any  sale  of  additional 
noncontrolling  interests  in  or  the  issuance  of  debt  of  Transocean Partners.    However,  current  market  conditions  may  make  any  such 
transaction challenging.  Subject in each case 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. 

At any given time, we may require a significant portion of our cash on hand for working capital and other needs related to the 
operation of our business.  We currently estimate this amount to be approximately $1.3 billion.  We expect to reduce this required amount 
to approximately $800 million as an outcome of our ongoing organizational efficiency initiatives and in the event our industry stabilizes.  As 
a result, this portion of cash is not generally available to us for other uses.  From time to time, we may also use borrowings under our bank 
credit agreement to maintain liquidity for short-term cash needs. 

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  their  credit  ratings  of  our  non-credit 
enhanced  senior  unsecured  long-term  debt  (“Debt  Rating”)  to  Debt  Ratings  that  are  below  investment  grade,  and  subsequent  to 
December 31, 2015, one of the credit rating agencies further downgraded our Debt Rating and another rating agency placed us on review 
for further downgrade.  Such downgrades have caused, and any further downgrades may cause, us to experience increased fees under 
our  credit  facility  and  interest  rates  under  agreements  governing  certain  of  our  senior  notes  and  may  limit  our  ability  to  access  debt 
markets.  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 flow is 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 flow from operations may be reduced.  We have, 
however, continued to generate positive cash flow from operating activities over recent years and expect that such cash flow will continue 
to be positive over the next year. 

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,  shareholders  at  our  extraordinary  general  meeting  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  June 18,  September 17  and  December 17,  2014,  we  paid  the  first three installments  in  the  aggregate  amount  of 
$816 million to shareholders of record as of May 30, August 22 and November 14, 2014, respectively.  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. 

In May 2013, 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 $2.24 per outstanding share, payable in four quarterly installments, subject  to certain 
limitations.    On  March 19,  2014,  we  paid  the  final  installment  in  the  aggregate  amount  of  $202 million  to  shareholders  of  record  as  of 
February 21, 2014.

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

subsidiary. 

Litigation settlements and insurance recoveries—On May 20, 2015, we entered into a confidential settlement agreement with 
BP  to  settle  various  disputes  remaining  between  the  parties  with  respect  to  the  Macondo  well  incident.    Pursuant  to  the  terms  of  the 
agreement, among other things, BP made a cash payment of $125 million in July 2015 to partially reimburse us for legal fees incurred by 
us. 

Additionally, in connection with the settlement, BP agreed to discontinue its attempts to recover as an additional insured under 
our liability insurance program.  As a result, we submitted claims to our insurers and recognized income of $538 million, recorded as a 
reduction  of  operating  and  maintenance  costs  and  expenses,  associated  with  insurance  proceeds  for  recovery  of  previously  incurred 
losses. 

On May 29, 2015, together with the PSC, we filed a 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  BP  had  made  against  us  and  had  assigned  to  private  plaintiffs  who  previously  settled 
economic  damages  claims  against  BP.    This  PSC  settlement  is  subject  to  approval  by  the  MDL Court  and  acceptance  by  a  minimum 
number of plaintiffs.  In August 2015, we made a cash deposit of $212 million into an escrow account pending approval of the settlement 
by the MDL Court. 

Effective October 13, 2015, we finalized a settlement agreement with the States, pursuant to which the States agreed to release 
all  of  their  claims  against  us  arising  from  the  Macondo  well  incident.    On  October 22,  2015,  we  made  an  aggregate  cash  payment  of 
$35 million to the States. 

Pursuant  to  a  cooperation  guilty  plea  agreement  by  and  among  the  U.S.  Department  of  Justice  (“DOJ”)  and  certain  of  our 
affiliates (the “Plea Agreement”), 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 the years ended December 31, 2015 and 2014, we 
made an aggregate cash payment of $60 million in each year.  On February 12, 2016, we made an aggregate cash payment of $60 million.  
At February 16, 2016, the remaining balance of our Plea Agreement obligations was $60 million, which is due on or before February 14, 
2017. 

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  pay  a  civil  penalty  totaling  $1.0 billion,  plus  interest  at  a  fixed  rate  of 
2.15 percent.    In  the  years  ended  December 31,  2015  and  2014,  we  paid  the  final  two  installments  of  $204 million  and  $412 million, 
respectively, including interest. 

Noncontrolling interest—On August 5, 2014, we completed the initial public offering of 20.1 million common units representing 
limited liability company interests in Transocean Partners, which trade on the New York Stock Exchange under the ticker symbol “RIGP”.  
Through  Transocean Partners Holdings Limited,  a  Cayman  Islands  company  and  our  wholly  owned  subsidiary,  we  hold  the  remaining 
21.3 million common units and 27.6 million subordinated units and all of the incentive distribution rights.  As a result of the offering, we 
received  net  cash  proceeds  of  approximately  $417 million,  after  deducting  approximately  $26 million  for  underwriting  discounts  and 
commissions and other estimated offering expenses.  We may consider selling additional noncontrolling interests in or debt securities of 
Transocean Partners to provide additional sources of liquidity, although current market conditions may make such offerings challenging. 

In February 2016, Transocean Partners declared and paid an aggregate distribution of $25 million, of which $7 million was paid 
to holders of noncontrolling interest and $18 million was paid to us and was eliminated in consolidation.  In the year ended December 31, 
2015, Transocean Partners declared and paid an aggregate distribution of $100 million to its unitholders, of which $29 million was paid to 
the holders of noncontrolling interest and $71 million was paid to us and was eliminated in consolidation.  In the year ended December 31, 
2014, Transocean Partners declared and paid an aggregate distribution of $15 million to its unitholders, of which $4 million was paid to the 
holders of noncontrolling interest and $11 million was paid to us and was eliminated in consolidation. 

On  November 4,  2015,  Transocean Partners  announced  that  its  board  of  directors  approved  a  unit  repurchase  program, 
authorizing it to repurchase up to $40 million of its publicly held common units.  Subject to market conditions, Transocean Partners may 
repurchase units from time to time in the open market or in privately negotiated transactions.  It may suspend or discontinue the program at 
any  time.    The  common  units  repurchased  under  the  program  will  be  cancelled.    As  of  February 16,  2016,  Transocean Partners  had 
repurchased 306,967 of its publicly held common units for an aggregate purchase price of $3 million.  At February 16, 2016, we  held a 
71.1 percent limited liability company interest in Transocean Partners. 

Debt redemptions and repurchases—In September 2010, we issued $1.1 billion aggregate principal amount of 4.95% Senior 
Notes.    On  November 17,  2014,  we  made  an  aggregate  cash  payment  of  $216 million  to  redeem  an  aggregate  principal  amount  of 
$207 million of the outstanding 4.95% Senior Notes.  On July 30, 2015, we made an aggregate cash payment of $904 million to redeem 
the  remaining  aggregate  principal  amount  of  $893 million  of  the  4.95% Senior Notes.    In  the  year  ended  December 31,  2015,  we  also 
made an aggregate cash payment of $468 million for open market repurchases of an aggregate principal amount of $503 million of certain 
of our publicly traded debt securities. 

AR-44 

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 debt to tangible capitalization ratio of 0.6 to 1.0.  At December 31, 2015, our debt to 
tangible capitalization ratio, as defined, 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. 

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 depending on our Debt Rating.  At February 16, 2016, based on our Debt 
Rating  on  that  date,  the  Five-Year  Revolving  Credit  Facility  Margin  was  1.75 percent  and  the  facility  fee  was  0.275 percent.    At 
February 16, 2016, we had no borrowings outstanding, no letters of credit issued, and $3.0 billion of available borrowing capacity under the 
Five-Year Revolving Credit Facility. 

Eksportfinans Loans—We have outstanding borrowings under the Loan Agreement dated September 12, 2008 (“Eksportfinans 
Loan A”)  and  outstanding  borrowings  under  the  Loan  Agreement  dated  November 18,  2008  (“Eksportfinans  Loan B,”  and  together  with 
Eksportfinans  Loan A,  the  “Eksportfinans  Loans”),  between  one  of  our  subsidiaries  and  Eksportfinans ASA,  which  were  established  to 
finance  the  construction  and  delivery  of  the  harsh  environment  ultra-deepwater  semisubmersibles  Transocean Spitsbergen  and 
Transocean Barents.  Eksportfinans Loan A and Eksportfinans Loan B bear interest at a fixed rate of 4.15 percent and require semi-annual 
installments  of  principal  and  interest  through  September 2017  and  January 2018,  respectively.    At  February 16,  2016,  aggregate 
borrowings of approximately $196 million were outstanding under Eksportfinans Loan A and Eksportfinans Loan B. 

The Eksportfinans Loans require restricted cash investments to be held at a certain financial institution through expiration (the 
“Eksportfinans Restricted Cash Investments”).  The Eksportfinans Restricted Cash Investments bear interest at a fixed rate of 4.15 percent 
with  semi-annual  installments  that  correspond  with  those  of  the  Eksportfinans  Loans.    At  February 16,  2016,  the  aggregate  principal 
amount of the Eksportfinans Restricted Cash Investments was $196 million. 

Share  repurchase  program—In  May 2009,  at  our  annual  general  meeting,  our  shareholders  approved  and  authorized  our 
board  of  directors,  at  its  discretion,  to  repurchase  an  amount  of  our  shares  for  cancellation  with  an  aggregate  purchase  price  of  up  to 
CHF 3.5 billion, which is equivalent to approximately $3.5 billion at an exchange rate as of the close of trading on February 16, 2016 of 
$1.00  to  CHF 0.99.    On  February 12,  2010,  our  board  of  directors  authorized  our  management  to  implement  the  share  repurchase 
program.  We intend to fund any repurchases using available cash balances and cash from operating activities.  On May 24, 2013, we 
received approval from the Swiss authorities for the continuation of the share repurchase program for an additional three-year repurchase 
period through May 23, 2016.  Upon the delisting of our shares from the SIX becoming effective, which we expect to occur on March 31, 
2016,  the  authorization  of  any  new  share  repurchase  program  and  the  continuation  of  the  share  repurchase  program  approved  at  the 
2009 annual  general  meeting  will  no  longer  be  subject  to  approval  requirements  from  the  Swiss  authorities.    In  the  year  ended 
December 31, 2015, we did not purchase shares under our share repurchase program. 

We may decide, based upon our ongoing capital requirements, our program of distributions to our shareholders, the price of our 
shares,  regulatory  and  tax  considerations,  cash  flow  generation,  the  amount  and  duration  of  our  contract  backlog,  general  market 
conditions, debt ratings considerations and other factors, that we should retain cash, reduce debt, make capital investments or acquisitions 
or otherwise use cash for general corporate purposes, and consequently, repurchase fewer or no additional shares under this program.  
Decisions regarding the amount, if any, and timing of any share repurchases will be made from time to time based upon these factors. 

Any shares repurchased under this program are expected to be purchased from time to time, from market participants that have 
acquired  those  shares  on  the  open  market  and  that  can  fully  recover  Swiss  withholding  tax  resulting  from  the  share  repurchase.  
Repurchases  could  also  be  made  by  tender  offer,  in  privately  negotiated  transactions  or  by  any  other  share  repurchase  method.    The 
share repurchase program could be suspended or discontinued by our board of directors or company management, as applicable, at any 
time.  Any repurchased shares would be held by us for cancellation by the shareholders at a future general meeting of shareholders.  On 
October 29, 2015, shareholders at our extraordinary general meeting approved the cancellation of all shares that have been repurchased 
to  date  under  our  share  repurchase  program.    The  shares  repurchased  under  our  share  repurchase  program  were  cancelled  as  of 
January 7, 2016 upon registration of the cancellation in the commercial register. 

AR-45 

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 16, 2016, Transocean Inc., our wholly owned subsidiary, held as treasury 
shares  approximately  two percent  of  our  issued  shares.    At  the  annual  general  meeting  in  May 2009,  the  shareholders  approved  the 
release of CHF 3.5 billion of additional paid-in capital to other reserves, or freely available reserves as presented on our Swiss statutory 
balance sheet, to create the freely available reserve necessary for the CHF 3.5 billion share repurchase program for the purpose of the 
cancellation  of  shares  (the  “Currently  Approved  Program”).    At  the  May 2011  annual  general  meeting,  our  shareholders  approved  the 
reallocation of CHF 3.2 billion, which is the remaining amount authorized under the share repurchase program, from free reserve to legal 
reserve,  reserve  from  capital  contributions.    This  amount  will  continue  to  be  available  for  Swiss  federal  withholding  tax-free  share 
repurchases.  We may only repurchase shares to the extent freely distributable reserves are available.  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 eight 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.

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

(a) 
(b)  As of December 31, 2015, our defined benefit pension and other postretirement plans represented an aggregate liability of $407 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  Plans  and  Other  Postretirement 
Benefit Plans” and Notes to Consolidated Financial Statements—Note 13—Postemployment Benefit Plans. 
As of December 31, 2015, our unrecognized tax benefits related to uncertain tax positions, net of prepayments, represented a liability of $405 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  a  number  of  committed  and  uncommitted  bank  credit  facilities.    The  obligations  that  are  the  subject  of  these 
standby letters of credit and surety bonds are primarily geographically concentrated in Nigeria 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, 2015, 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, 2015, the 
cash investments held by the captive insurance company totaled $192 million, and the amount of such cash investments is expected to 
range  from  $100 million  to  $225 million  by  December 31,  2016.    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. 

Derivative instruments 

Our board of directors has approved policies and procedures for derivative instruments that require the approval of our Chief 
Financial Officer prior to entering into any derivative instruments.  From time to time, we may enter into a variety of derivative instruments 
in  connection  with  the  management  of  our  exposure  to  fluctuations  in  interest  rates  or  currency  exchange  rates.    We  do  not  enter  into 
derivative transactions for speculative purposes; however, we may enter into certain transactions that do not meet the criteria for hedge 
accounting.  See Notes to Consolidated Financial Statements—Note 12—Derivatives and Hedging and Note 25—Subsequent Events. 

Pension Plans and Other Postretirement Benefit Plans 

Overview—In connection with actions taken by us prior to December 31, 2015, benefits under all of our remaining U.S. defined 
benefit pension  plans had ceased accruing or were scheduled to cease accruing by March 31, 2016.  We will  continue to maintain  the 
respective pension obligations under such plans until they have been fully satisfied.  As of December 31, 2015, we maintained one funded 
qualified benefit plan, which primarily covers employees on the U.S. payroll that work outside of the U.S., that will cease to accrue benefits, 
effective March 31, 2016.  Effective January 1, 2015, we formalized amendments to cease accruing benefits under our funded qualified 
defined benefit  pension plan, which previously  covered substantially all of our  U.S. employees, and a supplemental benefit plan, which 
previously provided certain eligible employees with benefits in excess of those allowed under the funded qualified defined benefit plan.  We 
also maintain one funded and two unfunded defined benefit plans that had previously ceased accruing benefits.  We refer to these plans, 
collectively, as the “U.S. Plans.” 

As  of  December 31,  2015,  we  maintain  a  defined  benefit  plan  in  the  U.K.  (the  “U.K. Plan”),  which  covers  certain  current  and 
former employees in the U.K.  In January 2016, we and the plan trustees mutually agreed to cease accruing benefits under the U.K. Plan, 
effective March 31, 2016.  We also maintain six funded and two unfunded defined benefit plans, primarily group pension schemes with life 
insurance  companies,  which  cover  certain  eligible  Norway  employees  and  former  employees  (the  “Norway  Plans”).    Additionally,  we 
maintain certain unfunded defined benefit plans that provide retirement and severance benefits for certain eligible Nigerian and Indonesian 
employees.  We also previously maintained an end-of-service benefit plan for certain of our Egyptian employees, for which we satisfied all 
obligations in the year ended December 31, 2015.  We refer to the U.K. Plan, the Norway Plans and the plans in Nigeria, Indonesia and 
Egypt, 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  have  several 
unfunded contributory and noncontributory other postretirement employee benefit plans (the “OPEB Plans”) covering substantially all of our 
U.S.  employees.    On  August 25,  2015,  we  announced  amendments  to  our  OPEB Plans  that  provide  for  declining  benefits  to  eligible 
participants during a phase-out period ending December 31, 2025.

(a) 

In the years ended December 31, 2015 and  2014,  net periodic benefit  costs were reduced  by expected returns  of  $115 million and  $103 million, 
respectively, from plan assets. 
(b)  Amounts presented before tax. 
(c)  Weighted-average based on relative average projected benefit obligation for the year. 
(d)  Weighted-average based on relative average fair value of plan assets for the year. 
(e)  Ultimate health care trend rate is expected to be reached in 2023. 

Net periodic benefit cost—In the year ended December 31, 2015, net periodic benefit costs decreased $49 million and, in the 
year ending December 31, 2016, we expect net periodic benefit costs to decrease by approximately $25 million, primarily as a result of our 
decision to cease accruing benefits under the U.S. Plans. 

Plan assets—We review our investment policies at least annually and our plan assets and asset allocations at least quarterly to 
evaluate performance relative to specified objectives.  In determining our asset allocation strategies for the U.S. Plans, we review 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 
returns under the terms of investment contracts with insurance companies. 

In the year ended December 31, 2015, plan assets of the funded Transocean Plans were favorably impacted by improvements in 
world equity markets, given the allocation of approximately 50 percent of plan assets to equity securities.  To a lesser extent, plan assets 
allocated to debt securities and other investments also experienced better than expected gains.  In the year ended December 31, 2015, 
the  fair  value  of  the  investments  in  the  funded  Transocean Plans  decreased  by  $122 million,  or  seven percent,  due  to  the  following: 
(a) approximately $74 million resulting from funding contributions, net of benefits paid, (b) approximately $39 million resulting from currency 
appreciation in connection with our funded Non-U.S. Plans, and (c) approximately $9 million resulting from investment returns. 

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  U.S.  Plans,  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.

For  the  year  ending  December 31,  2016,  we  expect  to  contribute  $52 million  to  the  Transocean Plans  and  $3 million  to  the 
OPEB Plans.  These estimated contributions for the Transocean Plans are comprised of $45 million to meet the funding requirements for 
the funded Non-U.S. Plans, and approximately $7 million to fund expected benefit payments for the unfunded U.S. Plans and unfunded 
Non-U.S. Plans.

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”).  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 MDL Court.  A significant portion of the contingencies arising from the 
Macondo well  incident  has  now  been  resolved  as  a  result  of  settlements  with  the  DOJ,  BP,  the  PSC  and  the  States.    We  believe  the 
remaining most notable claims against us arising from the Macondo well incident are the potential 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, 
the timing of any upcoming appeal or further rulings, 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 14—Commitments  and 
Contingencies. 

Tax matters 

We are a Swiss corporation, and we operate through our various subsidiaries in a number of countries throughout the world.  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.  Generally, our annual marginal tax rate is lower than our annual effective tax rate. 

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.  We are 
also defending against tax-related claims in courts, including our ongoing civil trial in Norway.  In January 2016, the Norwegian authorities 
formally and unconditionally dropped all criminal charges against our subsidiaries and the two employees of our former external advisors 
and  our  former  external  Norwegian  attorney.    As  a  result,  no  criminal  charges  remain  outstanding  for  any  of  the  previously  reported 
Norway tax investigations or trials and all our subsidiaries and external advisors have been fully acquitted of all criminal charges. 

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.

Regulatory matters 

For  a  description  of  regulatory  and  environmental  matters  relating  to  the  Macondo well  incident,  please  see  “—Macondo well 

incident.” 

Other 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. 

Off-Balance Sheet Arrangements 

We had no off-balance sheet arrangements as of December 31, 2015. 

Related Party Transactions 

As  of  December 31,  2015,  we  did  not  have  any  material  related  party  transactions  that  were  not  in  the  ordinary  course  of 

business. 

Critical Accounting Policies and Estimates 

Overview—We prepared 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, investments, property and equipment, income taxes, defined benefit pension 
plans  and  other  postretirement  employee  benefits,  contingent  liabilities  and  share-based  compensation.    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. 

We  consider  the  following  to  be  our  critical  accounting  policies  and  estimates,  and  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. 

Income taxes—We are a Swiss corporation, operating through our various subsidiaries in a number of countries throughout the 
world.  We have provided for income taxes based upon the tax laws and rates in the countries in which we operate and earn income.  The 
relationship between the provision for or benefit from income taxes and our income or loss before income taxes can vary significantly from 
period to period because the countries in which we operate have taxation regimes that vary with respect to the nominal tax rate and the 
availability of deductions, credits and other benefits.  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 ultimate tax liabilities in the various jurisdictions are determined. 

We maintain 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.    Tax  exposure  items  include  potential 
challenges  to  permanent  establishment  positions,  intercompany  pricing,  disposition  transactions,  and  withholding  tax  rates  and  their 
applicability.  These 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.  At December 31, 
2015, the liability for estimated tax exposures in our jurisdictions of operation was approximately $405 million. 

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 

AR-50 

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 consider the earnings of certain of our subsidiaries to be indefinitely reinvested.  As such, we have not provided for taxes on 
these unremitted earnings.  At December 31, 2015, the amount of indefinitely reinvested earnings was approximately $2.2 billion.  Should 
we make a distribution from the unremitted earnings of these subsidiaries, we would be subject to taxes payable to various jurisdictions.  
We estimate taxes in the range of $200 million to $250 million would be payable upon distribution of all previously unremitted earnings at 
December 31, 2015. 

We have recognized deferred taxes related to the earnings of certain subsidiaries that are not permanently reinvested or that will 
not  be  permanently  reinvested  in  the  future.    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. 

Estimates, judgments and assumptions are required in determining whether deferred tax assets will be fully or partially realized.  
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.    We  continually  evaluate  strategies  that  could  allow  for  the  future  utilization  of  our  deferred  tax  assets.  
During  the  year  ended  December 31,  2015,  in  evaluating  our  future  realization  of  deferred  tax  assets  we  took  into  account  plans  to 
centralize ownership of certain rigs among our subsidiaries, which resulted in utilization of additional deferred tax assets against income 
from  operations.    During  the  years  ended  December 31,  2014  and  2013,  we  did  not  make  any  significant  changes  to  our  valuation 
allowance against 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, 2015 and 2014, the carrying 
amount  of  our  property  and  equipment  was  $20.8 billion  and  $21.5 billion,  representing  79 percent  and  75 percent  of  our  total  assets, 
respectively. 

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,  2015,  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  $41 million  and  a  hypothetical  one-year  decrease  would  cause  an  increase  in  our  annual 
depreciation expense of approximately $61 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, Transocean Partners ultra-deepwater floaters, harsh environment floaters, deepwater floaters, midwater floaters, 
and high-specification jackups. 

We assess recoverability of assets held and used by projecting undiscounted cash flows for the asset group being evaluated.  
When  the  carrying  amount  of  the  asset  group  is  determined  to  be  unrecoverable,  we  recognize  an  impairment  loss,  measured  as  the 

AR-51 

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. 

During the three months ended  March 31, 2015, we identified indicators  that the asset groups in our contract drilling  services 
reporting  unit  may  not  be  recoverable.    Such  indicators  included  a  reduction  in  the  number  of  new  contract  opportunities,  recent  low 
dayrate  fixtures  and  contract  terminations.    Our  deepwater  floater  asset  group,  in  particular,  experienced  further  declines  in  projected 
dayrates  and  utilization  partly  caused  by  more  technologically  advanced  drilling  units  aggressively  competing  with  less  capable  drilling 
units.    During  the  three months  ended  June 30,  2015,  we  identified  additional  indicators  that  the  asset  groups  in  our  contract  drilling 
services  reporting  unit  may  not  be  recoverable.    Such  indicators  included  additional  customer  suspensions  of  drilling  programs  and 
cancellations of contracts, and further reduction in the number of new contract opportunities, resulting in reduced dayrate fixtures.  Our 
midwater floater asset group, specifically, experienced further declines in projected dayrates and utilization as drilling activity has sharply 
declined in the United Kingdom (“U.K.”) and Norwegian North Sea, which has accelerated the marginalization of some of the less capable 
drilling  units  in  this  asset  group.    As  a  result  of  our  testing,  we  determined  that  the  carrying  amounts  of  the  deepwater  floater  and  the 
midwater floater asset groups were impaired.  In the year ended December 31, 2015, we recognized a loss 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, including a loss of $52 million associated with construction in progress.  In each case, we measured the 
fair  value  of  the  asset  group  by  applying  a  combination  of  income  and  cost  approaches,  using  projected  discounted  cash  flows  and 
estimates of the exchange price that would be received for the assets in the principal or most advantageous market for the assets in an 
orderly transaction between market participants as of the measurement date.  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. 

During  the  year  ended  December 31,  2014,  we  identified  indicators  that  our  asset  groups  in  our  contract  drilling  services 
reporting unit may be impaired as a result of recent market developments, including recent low dayrate fixtures, partly caused  by more 
technologically  advanced  drilling  units  competing  with  less  capable  drilling  units,  and  projected  declines  in  dayrates  and  utilization, 
particularly for the deepwater floater asset group.  We conducted testing for impairment, and as a result, we determined that the carrying 
amount  of  the  deepwater  floater  asset  group  exceeded  its  fair  value.    In  the  year  ended  December 31,  2014,  we  recognized  a  loss  of 
$788 million ($693 million, net of tax) associated with the impairment of these long-lived assets.  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. 

See Notes to Consolidated Financial Statements—Note 5 Impairments. 

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.  The litigation and investigations 
also give rise to certain loss contingencies that we believe are reasonably possible.  Although we have not recognized a liability for such 
loss  contingencies,  these  contingencies  could  increase  the  liabilities  we  ultimately  recognize.    As  of  December 31,  2015  and  2014,  the 
liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $250 million 
and $426 million, respectively, recorded in other current liabilities. 

See Notes to Consolidated Financial Statements—Note 14—Commitments and Contingencies. 

AR-52 

Pension  and  other  postretirement  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 
postretirement  benefit  plans,  including  retiree  life  insurance  and  medical  benefits,  are  actuarially  determined  and  are  affected  by 
assumptions,  including  long-term  rate  of  return,  discount  rates,  mortality  rates,  compensation  increases,  employee  turnover  rates  and 
health care cost trend rates.  The two most critical assumptions are the long-term rate of return and the discount rate.  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 Plans and Other Postretirement Benefit Plans.” 

Long-term rate of return—We develop our assumptions regarding the estimated rate of return on plan assets based on historical 
experience and projected long-term investment returns, considering each plan’s target asset allocation and long-term asset class expected 
returns.  We regularly review our actual asset allocation and periodically rebalance plan assets as appropriate.  At December 31, 2015, a 
hypothetical  percentage  point  decrease  of  the expected  long-term rate  of return  assumption  would  result  in an  increase  to  net  periodic 
benefit costs of approximately $16 million. 

Discount  rate—As  a  basis  for  determining  the  discount  rate,  we  utilize  a  yield  curve  approach  based  on  Aa-rated  corporate 
bonds and the expected timing of future benefit payments.  At December 31, 2015, a hypothetical one-half percentage point decrease of 
the discount rate would result in an increase to net periodic benefit costs of approximately $2 million.

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

Interest  rate  risk—At  December 31,  2015  and 2014,  the  notional  amount  of  our  variable-rate  instruments  was approximately 
$750 million  and  $1.5 billion,  which  represented  nine percent  and  15 percent  of  the  aggregate  principal  amount  of  our  total  debt, 
respectively, including the effect of our hedging activities.  At December 31, 2015 and 2014, we were exposed to the variable interest rates 
associated with our interest rate swaps.  Based upon variable-rate notional amounts outstanding as of December 31, 2015 and 2014, a 
hypothetical one percentage point change in annual interest rates would result in a corresponding change in annual interest expense of 
approximately $8 million and $15 million, respectively. 

At December 31, 2015 and 2014, the fair value of our debt was $6.3 billion and $9.8 billion, respectively.  During the year ended 
December 31, 2015, the fair value of our debt decreased by $3.5 billion due to the following: (a) a decrease of approximately $1.5 billion 
resulting  from  the  repurchase  or  redemption  of  $1.5 billion  aggregate  principal  amount  of  debt  and  (b) a  decrease  of  approximately 
$2.0 billion resulting from the reduced fair value of our outstanding debt. 

A large portion of our cash investments is subject to variable interest rates and would earn commensurately higher rates of return 
if  interest  rates  increase.    Based  upon  the  amounts  of  our  cash  investments  as  of  December 31,  2015  and  2014,  a  hypothetical 
one percentage  point  change  in  interest  rates  would  result  in  a  corresponding  change  in  annual  interest  income  of  approximately 
$23 million and $26 million, respectively. 

Currency exchange rate risk—We are exposed to currency exchange rate risk associated with our international operations and 
with some of our long-term and short-term debt.  We may engage in hedging activities to mitigate our exposure to currency exchange risk 
in  certain  instances  through  the  use  of  currency  exchange  derivative  instruments,  including  forward  exchange  contracts,  or  spot 
purchases.  A forward exchange contract obligates us to exchange predetermined amounts of specified currencies at a stated exchange 
rate on a stated date or to make a U.S. dollar payment equal to the value of such exchange. 

For  our  international  operations,  our  primary  currency  exchange  rate  risk  management  strategy  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  acceptance,  local  banking  laws,  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 effect of fluctuations in currency exchange rates caused by our international operations generally has not had a 
material impact on our overall operating results.  In situations where local currency receipts do not equal local currency requirements, we 
may  use  currency  exchange  derivative  instruments,  including  forward  exchange  contracts,  or  spot  purchases,  to  mitigate  our  currency 
exchange risk. 

At December 31, 2015, we had NOK 1.9 billion aggregate principal amount of debt obligations, all of which were secured by a 
corresponding amount of restricted cash investments that were also denominated in Norwegian kroner.  These corresponding restricted 
cash investments form an economic hedge of our exposure to currency exchange rate risk associated with these debt obligations.

Financial Statements and Supplementary Data 

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING 

Management  of  Transocean Ltd.  (the  “Company”  or  “our”)  is  responsible  for  establishing  and  maintaining  adequate  internal 
control over financial reporting for the Company as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934.  
The  Company’s  internal  control  system  was  designed  to  provide  reasonable  assurance  to  the  Company’s  management  and  board  of 
directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
United States (“U.S.”) generally accepted accounting principles. 

Internal control over financial reporting includes the controls themselves, monitoring (including internal auditing practices), and 

actions taken to correct deficiencies as identified. 

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

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2015.  In 
making this assessment, management used the criteria for internal control over financial reporting described in Internal Control-Integrated 
Framework,  as  published  in  2013  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.    Management’s 
assessment included an evaluation of the design of the Company’s internal control over financial reporting and testing of the operating 
effectiveness of its internal control over financial reporting. 

Management reviewed the results of its assessment with the audit committee of the Company’s board of directors.  Based on 
this assessment, management has concluded that, as of December 31, 2015, the Company’s internal control over financial reporting was 
effective. 

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 Board of Directors and Shareholders of Transocean Ltd.  

We have audited Transocean Ltd. and subsidiaries’ internal control over financial reporting as of December 31, 2015, 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).    Transocean Ltd.  and  subsidiaries’  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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over 
financial reporting was maintained in all material respects.  Our audit included obtaining an understanding of internal control over financial 
reporting,  assessing  the  risk  that  a  material  weakness  exists,  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal 
control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances.  We believe 
that our audit provides a reasonable basis for our opinion. 

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  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. 

In  our  opinion,  Transocean Ltd.  and  subsidiaries  maintained,  in  all  material  respects,  effective  internal  control  over  financial 

reporting as of December 31, 2015, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated  balance  sheets  of  Transocean Ltd.  and  subsidiaries  as  of  December 31,  2015  and  2014,  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, 2015, and our report dated February 24, 2016 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors and Shareholders of Transocean Ltd. 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Transocean Ltd.  and  subsidiaries  (the  “Company”)  as  of 
December 31,  2015  and  2014,  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, 2015.  Our audits also included the financial statement schedule listed 
in  the  Index  at  Item 15(a).    These  financial  statements  and  schedule  are  the  responsibility  of  the  Company's  Board  of  Directors  and 
management.  Our responsibility is to express an opinion on these financial statements and schedule based on our audits. 

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position 
of Transocean Ltd. and subsidiaries at December 31, 2015 and 2014, and the consolidated results of their operations and their cash flows 
for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.  Also, 
in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, 
presents fairly in all material respects the information set forth therein. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
Transocean Ltd.  and  subsidiaries’  internal  control  over  financial  reporting  as  of  December 31,  2015,  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 24, 2016 expressed an unqualified opinion thereon.

To the General Meeting of 
Transocean Ltd., Steinhausen 

Zurich, February 24, 2016 

Report of the statutory auditor on the consolidated financial statements 
As  statutory  auditor,  we  have  audited  the  consolidated  financial  statements  of  Transocean Ltd.  and  Subsidiaries,  which  comprise  the 
consolidated balance sheets as of December 31, 2015 and 2014 and the related consolidated statements of operations, comprehensive 
income (loss), equity, cash flows, and notes thereto for each of the three years in the period ended December 31, 2015 (pages AR-59 to 
AR-106). 

Board of Directors’ responsibility 
The Board of Directors is responsible for the preparation of the consolidated financial statements in accordance with accounting principles 
generally  accepted  in  the  United  States  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  audit.  We  conducted  our  audit  in 
accordance  with  Swiss  law,  Swiss  Auditing  Standards  and  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States).    Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  consolidated 
financial statements are free from material misstatement. 
An  audit  involves  performing  procedures  to  obtain  audit  evidence  about  the  amounts  and  disclosures  in  the  consolidated  financial 
statements.  The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of 
the consolidated financial 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 and fair presentation of the consolidated financial statements in order to design audit 
procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s 
internal control system.  An audit also includes evaluating the appropriateness of the accounting policies used and the 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. 

Opinion 
In  our  opinion,  the  consolidated  financial  statements  referred  to above  present  fairly,  in  all  material  respects,  the  consolidated  financial 
position of Transocean Ltd. and Subsidiaries at December 31, 2015 and 2014, and the consolidated results of their operations and their 
cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted 
in the United States and comply with Swiss law. 

Report on other legal requirements 
We  confirm  that  we  meet  the  legal  requirements  on  licensing  according  to  the  Auditor  Oversight  Act  (AOA)  and  independence 
(article 728 CO and article 11 AOA) and that there are no circumstances incompatible with our independence. 
In accordance with article 728a paragraph 1 item 3 CO and Swiss Auditing Standard 890, we confirm that an internal control system exists, 
which has been designed for the preparation of consolidated financial statements according to the instructions of the Board of Directors. 
We recommend that the consolidated financial statements submitted to you be approved.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 1—Business 

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” “we,” “us” 
or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas  wells.    We  specialize  in  technically 
demanding  sectors  of  the  offshore  drilling  business  with  a  particular  focus  on  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,  2015,  we  owned  or  had  partial  ownership 
interests  in  and  operated  60 mobile  offshore  drilling  units,  including  27 ultra-deepwater  floaters,  seven harsh  environment  floaters, 
five deepwater 
  At  December 31,  2015,  we  also  had 
seven ultra-deepwater drillships and five high-specification jackups under construction or under contract to be constructed.  See Note 9—
Drilling Fleet. 

floaters  and  10 high-specification 

floaters,  11 midwater 

jackups. 

On October 29, 2015, shareholders at our extraordinary general meeting 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.  See Note 16—Shareholders’ Equity and Note 25—Subsequent Events. 

On  August 5,  2014,  we  completed  an  initial  public  offering  to  sell  a  noncontrolling  interest  in  Transocean Partners LLC 
(“Transocean Partners”),  a  Marshall  Islands  limited  liability  company,  which  was  formed  on  February 6,  2014,  by  Transocean Partners 
Holdings Limited,  a  Cayman  Islands  company  and  our  wholly  owned  subsidiary,  to  own,  operate  and  acquire  modern,  technologically 
advanced offshore drilling rigs.  See Note 15—Noncontrolling Interest. 

In  February 2014,  in  connection  with  our  efforts  to  discontinue  non-strategic  operations,  we  completed  the  sale  of 
Applied Drilling Technology International Limited  (“ADTI”),  a  United Kingdom  (“U.K.”)  company,  which  performs  drilling  management 
services in the North Sea.  In March 2012, we announced our intent to discontinue drilling management operations in the shallow waters of 
the U.S. Gulf of Mexico, upon completion of our then existing contracts.  In December 2012, we completed the final project of our drilling 
management services operations in the U.S. Gulf of Mexico and discontinued offering our drilling management services in this region.  See 
Note 7—Discontinued Operations. 

Note 2—Significant Accounting Policies 

Accounting  estimates—To  prepare  financial  statements  in  accordance  with  accounting  principles  generally  accepted  in  the 
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 plans and other postretirement benefits.  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 15—Noncontrolling interest. 

Discontinued  operations—Under  accounting  standards  previously  in  effect,  we  presented  as  discontinued  operations  the 
operating  results  of  components  of  our  business  that  either  had  been  disposed  of  or  were  classified  as  held  for  sale  when  both  of  the 
following  conditions  were  met:  (a) the  operations  and  cash  flows  of  the  component  had  been  or  would  be  eliminated  from  our  ongoing 
operations as a result of the disposal transaction and (b) we would not have any significant continuing involvement in the operations of the 
disposed  component.    Under  the  former  accounting  standards,  we  considered  a  component  of  our  business  to  be  one that  comprises 

AR-64 

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

operations  and  cash  flows  that  can  be  clearly  distinguished,  operationally  and  for  financial  reporting  purposes,  from  the  rest  of  our 
business.  See Note 3—New Accounting Pronouncements and Note 7—Discontinued Operations. 

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  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 amortize contract drilling intangible revenues 
based  on  the  cash  flows  projected  over  the  respective  contract  period  and  include  such  revenues  in  contract  drilling  revenues  on  our 
consolidated  statements  of  operations  (see  Note 10—Intangible  Liabilities).    We  amortize,  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. 

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—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.    We  recognize  share-based 
compensation expense net of a forfeiture rate that we estimate at the time of grant based on historical experience and future expectations, 
and we adjust the estimated forfeiture rate, if necessary, in subsequent periods based on actual forfeitures or changed expectations. 

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.    The 
expected life is  based on historical information  of past employee behavior regarding exercises  and forfeitures of options.  The risk-free 
interest  rate  is  based  upon  the  published  U.S.  Treasury  yield  curve  in  effect  at  the  time  of  grant  or  modification  for  instruments  with  a 
similar life.  The dividend yield is based on our history and expectation of dividend payouts.  The expected volatility is based on a blended 
rate  with  an  equal  weighting  of  the  (a) historical  volatility  based  on  historical  data  for  an  amount  of  time  approximately  equal  to  the 
expected life and (b) implied volatility derived from our at-the-money, long-dated call options.  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.  The risk neutral approach assumes that all peer group stocks grow at the risk-free rate.  The 
average price at the performance start date is based on the average stock price for the preceding 30 trading days. 

We recognize share-based compensation expense in the same financial statement line item as cash compensation paid to the 
respective employees or non-employee directors.  We recognize cash flows resulting from the tax deduction benefits for awards in excess 
of  recognized  compensation  costs  as  financing  cash  flows.    In  the  years  ended  December 31,  2015,  2014  and  2013,  share-based 
compensation  expense  was  $67 million,  $98 million  and  $113 million,  respectively.    In  the  years  ended  December 31,  2015,  2014  and 
2013, income tax benefit on share-based compensation expense was $11 million, $15 million and $17 million, respectively.  See Note 17—
Share-Based Compensation Plans. 

Capitalized  interest—We  capitalize  interest  costs  for  qualifying  construction  and  upgrade  projects.    In  the  years  ended 
December 31,  2015,  2014  and  2013,  we  capitalized  interest  costs  of  $140 million,  $133 million  and  $78 million,  respectively,  for  our 
construction work in progress. 

Foreign 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  foreign  currency  exchange  gains  and  losses  in  other,  net.    In  the  years  ended  December 31,  2015,  2014  and  2013,  we 

AR-65 

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

recognized net foreign currency exchange gains (losses) of less than $1 million, $18 million and $(11) million, respectively.  See Note 12—
Derivatives and Hedging. 

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.  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  recognize  deferred  tax  assets  and  liabilities  for  the  anticipated  future  tax  effects  of  temporary  differences  between  the 
financial statement basis and the tax basis of our assets and liabilities using the applicable jurisdictional tax rates in effect at year end.  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.  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. 

We maintain restricted cash balances and investments that are either pledged for debt service, as required under certain bank 
credit  agreements,  or  held  in  accounts  that  are  subject  to  restrictions  due  to  legislation,  regulation  or  court  order.    We  classify  such 
restricted cash investment balances in other 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, 2015, the 
aggregate carrying amount of our restricted cash investments was $467 million, of which $340 million and $127 million was classified in 
other  current  assets  and  other  assets,  respectively.    At  December 31,  2014,  the  aggregate  carrying  amount  of  our  restricted  cash 
investments was $377 million, of which $114 million and $263 million was classified in other current assets and other assets, respectively.  
See Note 11—Debt and Note 14—Commitments and Contingencies. 

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 
do not generally 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, 2015 and 2014, the allowance for doubtful accounts was less than $1 million 
and $14 million, respectively. 

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, 2015 and 2014, the allowance for obsolescence was $148 million and $109 million, respectively. 

Assets  held  for  sale—We  classify  an  asset  as  held  for  sale  when  the  facts  and  circumstances  meet  the  criteria  for  such 
classification, including the following: (a) we have committed to a plan to sell the asset, (b) the asset is available for immediate sale, (c) we 
have initiated actions to complete the sale, including locating a  buyer, (d) the sale is expected  to be completed within one year, (e) the 
asset is being actively marketed at a price that is reasonable relative to its fair value, and (f) the plan to sell is unlikely to be subject to 
significant  changes  or  termination.    At  December 31,  2015  and  2014,  the  aggregate  carrying  amount  of  our  assets  held  for  sale  was 
$8 million and $25 million, respectively.  See Note 7—Discontinued Operations and Note 9—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,  2015,  the  aggregate  carrying  amount  of  our  property  and  equipment  represented 
approximately 79 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 

AR-66 

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

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

As of December 31, 2014, we adjusted the salvage values of certain drilling units due to existing market conditions.  In the year 
ended  December 31,  2015,  the  changes  in  estimated  salvage  values  resulted  in  an  increase  in  depreciation  expense  of  approximately 
$51 million ($48 million, or $0.13 per diluted share, net of tax).  During the year ended December 31, 2013, we adjusted the useful lives for 
five rigs, extending the estimated useful lives from between 29 and 40 years to between 35 and 44 years.  We deemed the life extensions 
appropriate for each of these rigs based on the respective contracts under which the rigs were operating and the additional life-extending 
work, upgrades and inspections we performed on the rigs.  In year ended December 31, 2013, the changes in estimated useful lives of 
these rigs resulted in a reduction in annual depreciation expense of $3 million ($0.01 per diluted share), which had no tax effect. 

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  and 
floaters,  Transocean Partners  ultra-deepwater 
high-specification  jackups.    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. 

floaters,  harsh  environment 

floaters,  deepwater 

floaters,  midwater 

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.  In the year ended December 31, 2014, we determined that the carrying amount of the deepwater 
floater asset group exceeded its fair value, and we recognized a loss of $788 million ($693 million, or $1.91 per diluted share, net of tax) 
associated  with  the  impairment  of  these  long-lived  assets.    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—Impairments. 

Goodwill impairment—Prior to the full impairment of our goodwill, we conducted impairment testing annually as of October 1 
and  more  frequently,  on  an  interim  basis,  when  an  event  occured  or  circumstances  changed  that  indicated  that  the  fair  value  of  our 
reporting unit may have declined below its carrying value.  We tested goodwill at the reporting unit level, which is defined as an operating 
segment or one level below an operating segment that constitutes a business for which financial information is available and is regularly 
reviewed by management.  We determined that we had a single reporting unit for this purpose. 

We estimate the fair value of our reporting unit using projected discounted cash flows, publicly traded company multiples and 
acquisition  multiples.    To  develop  the  projected  cash  flows  associated  with  our  reporting  unit,  which  are  based  on  estimated  future 
dayrates and rig utilization, we consider key factors that include assumptions regarding future commodity prices, credit market conditions 
and  the  effect  these  factors  may  have  on  our  contract  drilling  operations  and  the  capital  expenditure  budgets  of  our  customers.    We 
discount the projected cash flows using a long-term, risk-adjusted weighted-average cost of capital, which is based on our estimate of the 
investment returns that market participants would require for each of our reporting units.  We derive publicly traded company multiples for 
companies with operations similar to our reporting units using observable information related to shares traded on stock exchanges and, 
when  available,  observable  information  related  to  recent  acquisitions.    If  the  reporting  unit’s  carrying  amount  exceeds  its  fair  value,  we 
consider goodwill impaired and perform a second step to measure the amount of the impairment loss, if any. 

In  the  year  ended  December 31,  2014,  as  a  result  of  interim  goodwill  tests,  we  recognized  an  aggregate  loss  of  $3.0 billion, 
which had no tax effect, associated with the full impairment of the carrying amount of our goodwill, of which $2.9 billion ($8.02 per diluted

share) was attributable to controlling interest and $74 million was attributable to noncontrolling interest.  In the year ended December 31, 
2013, as a result of our annual goodwill impairment test, we concluded that our goodwill was not impaired.  See Note 5—Impairments. 

Derivatives and hedging—From time to time, we may enter into a variety of derivative financial instruments in connection with 
the management of our exposure to variability in interest rates and currency exchange rates.  We record derivatives on our consolidated 
balance  sheet,  measured  at  fair  value.    For  derivatives  that  do  not  qualify  for  hedge  accounting,  we  recognize  the  gains  and  losses 
associated with changes in the fair value in current period earnings. 

We  may  enter  into  cash  flow  hedges  to  manage  our  exposure  to  variability  of  the  expected  future  cash  flows  of  recognized 
assets or liabilities or of unrecognized forecasted transactions.  For a derivative that is designated and qualifies as a cash flow hedge, we 
initially recognize the effective portion of the gains or losses in other comprehensive income and subsequently recognize the gains and 
losses  in  earnings  in  the  period  in  which  the  hedged  forecasted  transaction  affects  earnings.    We  recognize  the  gains  and  losses 
associated with the ineffective portion of the hedges in interest expense in the period in which they are realized. 

We may enter into fair value hedges to manage our exposure to changes in fair value of recognized assets or liabilities, such as 
fixed-rate  debt,  or  of  unrecognized  firm  commitments.    For  a  derivative  that  is  designated  and  qualifies  as  a  fair  value  hedge,  we 
simultaneously recognize in current period earnings the gains or losses on the derivative along with the offsetting losses or gains on the 
hedged item attributable to the hedged risk.  The resulting ineffective portion, which is measured as the difference between the change in 
fair  value  of  the  derivative  and  the  hedged  item,  is  recognized  in  current  period  earnings.    See  Note 12—Derivatives  and  Hedging, 
Note 20—Financial Instruments and Note 21—Risk Concentration. 

Pension and other postretirement benefits—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 postretirement 
benefit  plans,  retiree  life  insurance  and  medical  benefits,  by  applying  assumptions,  including  long-term  rate  of  return  on  plan  assets, 
discount rates, mortality rates, compensation increases, employee turnover rates and health care cost trend rates.  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.    For  the  health  care  cost  trend  rate  for  other  postretirement 
benefits,  we  establish  our  assumptions  for  health  care  cost  trends,  applying  an  initial  trend  rate  that  reflects  both  our  recent  historical 
experience and broader national statistics with an ultimate trend rate that assumes that the portion of gross domestic product devoted to 
health care eventually becomes constant. 

At December 31, 2015 and 2014, our pension and other postretirement benefit plan obligations represented an aggregate liability 
of $412 million and $521 million, respectively, representing the amount of their net underfunded status.  In the years ended December 31, 
2015,  2014  and  2013,  net  periodic  benefit  costs  were  $26 million,  $75 million  and  $132 million,  respectively.    See  Note 13—
Postemployment Benefit Plans. 

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

Reclassifications—We  have  made  certain  reclassifications,  such  as  those  related  to  our  adoption  of  updates  to  accounting 
standards for interest and income taxes, which did not have an effect on net income, to prior period amounts to conform with the current 
year’s presentation.  These reclassifications did not have a material effect on our consolidated statement of financial position, results of 
operations or cash flows. 

Subsequent  events—We  evaluate  subsequent  events  through  the  time  of  our  filing  on  the  date  we  issue  our  financial 

statements.  See Note 25—Subsequent Events.

Note 3—New Accounting Pronouncements 

Recently adopted accounting standards 

Presentation of financial statements—Effective January 1, 2015, we adopted the accounting standards update that changes 
the  criteria  for  reporting  discontinued  operations.    The  update  expands  the  disclosures  for  discontinued  operations  and  requires  new 
disclosures related to the disposal of individually significant components of an entity that do not qualify for discontinued operations.  The 
update is effective for interim and annual periods beginning on or after December 15, 2014 and does not apply to components, such as our 
discontinued operations, that have been evaluated and reported as discontinued operations under previous guidance.  Our adoption did 
not have an effect on our consolidated financial statements or the disclosures contained in our notes to consolidated financial statements. 

Interest—Effective December 31, 2015, we elected to early adopt the accounting standards update that requires debt issuance 
costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt 
liability,  consistent  with  debt  discounts.    The  update  is  effective  for  interim  and annual  periods  beginning  after December 15,  2015  and 
early adoption is permitted.  At December 31, 2014, as a result of our adoption, we reclassified $41 million of debt issuance costs to our 
recognized debt liabilities from other assets on our consolidated balance sheet. 

Income  taxes—Effective  December 31,  2015,  we  elected  to  early  adopt,  on  a  retrospective  basis,  the  accounting  standards 
update that requires deferred tax liabilities and assets to be classified as noncurrent in a classified statement of financial position.  The 
update is effective for interim and annual periods beginning after December 15, 2016 and early adoption is permitted.  We elected to apply 
the accounting standards update to the prior year on a retrospective basis for comparability purposes.  At December 31, 2014, as a result 
of our adoption, we reclassified $161 million of deferred income taxes to noncurrent assets and long-term liabilities from current assets on 
our consolidated balance sheet. 

Recently issued accounting standards 

Presentation of financial statements—Effective with our annual report for the year ending December 31, 2016, we will adopt 
the accounting standards update that requires us to evaluate whether there are conditions or events, considered in the aggregate, that 
raise  substantial  doubt  about  our  ability  to  continue  as  a  going  concern  within  one year  after  the  date  that  the  financial  statements  are 
issued.  The update is effective for the annual period ending after December 15, 2016 and for interim and annual periods thereafter.  We 
do not expect that our adoption will have a material effect on the disclosures contained in our notes to consolidated financial statements. 

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 was originally effective for 
interim and annual periods beginning on or after December 15, 2016, but has since been approved for a one-year deferral, effective for 
interim and annual periods beginning on or after December 15, 2017, and permits adoption as early as the original effective date.  We are 
evaluating the requirements to determine the effect such requirements may have on our revenue recognition policies.

Angola Deepwater  Drilling  Company Limited  (“ADDCL”),  a  consolidated  Cayman  Islands  company,  and  Transocean Drilling 
Services Offshore Inc. (“TDSOI”), a consolidated British Virgin Islands Company, were joint venture companies formed to own and operate 
certain drilling units.  We determined that each of these joint venture companies 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 consolidated ADDCL and TDSOI in our consolidated financial  statements, we 
eliminated  intercompany  transactions,  and  we  presented  the  interests  that  were  not  owned  by  us  as  noncontrolling  interest  on  our 
consolidated balance sheets. 

In October 2012, Angco II, a Cayman Islands company, acquired a 30 percent interest in TDSOI, a British Virgin Islands joint 
venture  company  formed  to  own  and  operate  Transocean Honor.    We  hold  the  remaining  70 percent  interest  in  TDSOI.   Under  certain

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

circumstances, Angco II will have 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 high-specification jackup, subject to certain adjustments. 

Unconsolidated variable interest entities—We previously held two notes receivable, which represented a variable interest in 
Awilco  Drilling plc  (“Awilco”),  a  U.K.  company  listed  on  the  Oslo  Stock  Exchange.    The  notes  receivable  were  originally  accepted  in 
exchange for, and were secured by, two drilling units.  The notes receivable had stated interest rates of nine percent and were payable in 
scheduled  quarterly  installments  of  principal  and  interest  through  maturity  in  January 2015.    In  April 2014,  Awilco  prepaid  the  notes, 
liquidating our variable interest, and we received aggregate cash proceeds of $98 million and recognized a gain of $7 million, recorded in 
other income, associated with the prepayment. 

Note 5—Impairments 

Assets held and used—During the three months ended March 31, 2015, we identified indicators that the asset groups in our 
contract  drilling  services  reporting  unit  may  not  be  recoverable.    Such  indicators  included  a  reduction  in  the  number  of  new  contract 
opportunities, recent low dayrate fixtures and contract terminations.  Our deepwater floater asset group, in particular, experienced further 
declines in projected dayrates and utilization partly caused by  more technologically advanced  drilling units aggressively competing with 
less capable drilling units.  During the three months ended June 30, 2015, we identified additional indicators that the asset groups in our 
contract  drilling  services  reporting  unit  may  not  be  recoverable.    Such  indicators  included  additional  customer  suspensions  of  drilling 
programs and cancellations of contracts, and further reduction in the number of new contract opportunities, resulting in reduced dayrate 
fixtures.  Our midwater floater asset group, specifically, experienced further declines in projected dayrates and utilization as drilling activity 
has sharply declined in the United Kingdom (“U.K.”) and Norwegian North Sea, which has accelerated the marginalization of some of the 
less capable drilling units in this asset group.  As a result of our testing, we determined that the carrying amounts of the deepwater floater 
and  the  midwater  floater  asset  groups  were  impaired.    In  the  year  ended  December 31,  2015,  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.    In  each  case,  we  measured  the  fair  value  of  the  asset  group  by 
applying a combination of income and cost approaches, using projected discounted cash flows and estimates of the exchange price that 
would be received for the assets in the principal or most advantageous market for the assets in an orderly transaction between market 
participants as of the measurement date.  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. 

During  the  year  ended  December 31,  2014,  we  identified  indicators  that  our  asset  groups  in  our  contract  drilling  services 
reporting unit may be impaired as a result of recent market developments, including recent low dayrate fixtures, partly caused  by more 
technologically  advanced  drilling  units  competing  with  less  capable  drilling  units,  and  projected  declines  in  dayrates  and  utilization, 
particularly for the deepwater floater asset group.  We conducted testing for impairment, and as a result, we determined that the carrying 
amount  of  the  deepwater  floater  asset  group  exceeded  its  fair  value.    In  the  year  ended  December 31,  2014,  we  recognized  a  loss  of 
$788 million  ($693 million,  or  $1.91 per  diluted  share  from  continuing  operations,  net  of  tax)  associated  with  the  impairment  of  these 
long-lived assets.  We measured the fair value of the asset group by applying a combination of income, market and cost approaches, using 
projected  discounted  cash  flows  and  estimates  of  the  exchange  price  that  would  be  received  for  the  assets  in  the  principal  or  most 
advantageous market for the assets in an orderly transaction between market participants as of the measurement date.  Our estimate of 
fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions 
related to the future performance of our contract drilling services reporting unit, such as future commodity prices, projected demand for our 
services, rigs availability and dayrates. 

In the year ended December 31, 2013, we recognized a loss of $17 million associated with the impairment of certain corporate 
assets under construction.  We estimated the fair value of the assets using significant other observable inputs, representative of a Level 2 
fair value measurement, including comparable market data for the corporate assets. 

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. 

Assets held for sale—In the year ended December 31, 2015, we recognized an aggregate loss of $692 million ($578 million, or 
$1.58 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  the 
midwater  floaters  GSF Aleutian Key,  GSF Arctic III,  GSF Grand Banks,  GSF Rig 135,  Transocean Amirante  and  Transocean Legend, 
along with related equipment, which were classified as assets held for sale at the time of impairment.  We measured the impairment of the 
drilling units and related equipment 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 equipment to be sold for scrap value. 

AR-70 

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

In the year ended December 31, 2014, we recognized an aggregate loss of $268 million ($221 million, or $0.60 per diluted share 
from  continuing  operations,  net  of  tax)  associated  with  the  impairment  of  the  deepwater  floaters  Discoverer  Seven Seas,  Sedco 709, 
Sedco  710  and  Sovereign Explorer,  the  midwater  floaters  C. Kirk Rhein, Jr.,  Falcon 100,  GSF Arctic I,  J.W. McLean,  Sedco 601, 
Sedco 700,  Sedco 703  and  Sedneth 701  and  the  high-specification  jackups  GSF Magellan  and  GSF Monitor,  along  with  related 
equipment, which were classified as assets held for sale at the time of impairment.  We measured the impairments of the drilling units and 
related equipment 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, in the case of 
GSF Magellan  and  GSF Monitor,  binding  sale  and  purchase  agreements  for  the  drilling  units  and  related  equipment  or,  in  the  case  of 
Sedco 710, Sovereign Explorer, GSF Arctic I, J.W. McLean, Sedco 601 and Sedco 700, indicative market values for the drilling units and 
related equipment to be sold for scrap value. 

In the year ended December 31, 2013, we recognized an aggregate loss of $64 million ($0.17 per diluted share), which had no 
tax effect, associated with the impairment of the deepwater floater Sedco 709, the midwater floaters C. Kirk Rhein, Jr. and Sedco 703 and 
the high-specification jackup GSF Monitor, all of which were classified as assets held for sale at the time of impairment.  We measured the 
impairments of the drilling units and related equipment as the amount by which the carrying amounts exceeded the estimated fair values 
less costs to sell.  We estimated the fair values of the assets using significant other observable inputs, representative of Level 2 fair value 
measurements,  including,  in  the  case  of  GSF Monitor,  a  binding  sale  and  purchase  agreement,  or,  in  the  case  of  Sedco 709, 
C. Kirk Rhein, Jr. and Sedco 703, nonbinding sale and purchase agreements for the drilling units and related equipment. 

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. 

Goodwill—During the year ended December 31, 2014, we noted rapid and significant declines in the market value of our stock, 
oil and natural gas prices and actual and projected declines in dayrates and utilization.  We identified these as indicators that the fair value 
of our goodwill could have fallen below its carrying amount.  As a result, we performed interim goodwill impairment tests and determined 
that the goodwill associated with our contract drilling services reporting unit was fully impaired.  In the year ended December 31, 2014, we 
recognized an aggregate loss of $3.0 billion associated with the full impairment of the carrying amount of our goodwill, which had no tax 
effect.  We determined that, of the $3.0 billion aggregate loss, $2.9 billion ($8.02 per diluted share) was attributable to controlling interest 
and $74 million was attributable to noncontrolling interest.  We estimated the implied fair value of the goodwill using a variety of valuation 
methods,  including  the  income  and  market  approaches.    Our  estimate  of  fair  value  required  us  to  use  significant  unobservable  inputs, 
representative  of  a  Level 3  fair  value  measurement,  including  assumptions  related  to  the  future  performance  of  our  contract  drilling 
services reporting unit, such as future oil and natural gas prices, projected demand for our services, rig availability and dayrates.  As a 
result of our annual impairment test, performed as of October 1, 2013, we determined that our goodwill was not impaired. 

Note 6—Income Taxes 

Tax  rate—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.  At the federal level, qualifying net dividend income and net capital gains on the 
sale  of  qualifying  investments  in  subsidiaries  are  exempt  from  Swiss  federal  income  tax.    Consequently,  Transocean Ltd.  expects 
dividends from its subsidiaries and capital gains from sales of investments in its subsidiaries to be exempt from Swiss federal income tax. 

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.  Generally, our annual marginal tax rate is lower than our annual effective tax rate. 

Effective April 1, 2015, the U.K introduced the diverted profits tax within its Summer Finance Bill 2015, which imposes tax on 
groups that use certain tax planning techniques that are perceived as diverting profits from the U.K.  The change in the law did not affect 
our existing annual income tax rate or deferred tax balances.  In the years ended December 31, 2015, 2014 and 2013, our annual effective 
tax rate was 16.4 percent, 18.7 percent and 20.1 percent, respectively. 

On December 18, 2015, Norwegian authorities reduced the corporate income tax rate to 25 percent from 27 percent, effective 
January 1, 2016.  We have applied this change in determining our annual effective tax rate.  The change in Norwegian tax law resulted in a 
decrease  of  $11 million  to  income  tax  expense  resulting  from  the  application  of  the  newly  enacted  tax  rate  to  our  existing  deferred  tax 
balances.

At  December 31,  2015  and  2014,  our  deferred  tax  assets  included  U.S.  foreign  tax  credit  carryforwards  of  $23 million  and 
$14 million,  respectively,  which  will  expire  between  2017  and  2025.    The  deferred  tax  assets  related  to  our  net  operating  losses  were 
generated  in  various  worldwide  tax  jurisdictions.    At  December 31,  2015,  the  tax  effect  of  our  Norwegian  and  Brazilian  net  operating 
losses, which do not expire, was $77 million and $17 million, respectively, and the tax effect of our U.S. net operating loss, which expires in 
2035 was $42 million.  At December 31, 2014, the tax effect of our Norwegian and Brazilian net operating losses, which do not expire, was 
$108 million and $40 million, respectively. 

The valuation allowance for our deferred tax assets was as follows (in millions):

Our deferred tax liabilities include taxes related to the earnings of certain subsidiaries that are not permanently reinvested or that 
will not be permanently reinvested in the future.  Should our expectations change regarding future tax consequences, we may be required 
to record additional deferred taxes that could have a material adverse effect on our consolidated statement of financial position, results of 
operations or cash flows. 

We consider the earnings of certain of our subsidiaries to be indefinitely reinvested.  As such, we have not provided for taxes on 
these  unremitted  earnings.    Should  we  make  a  distribution  from  the  unremitted  earnings  of  these  subsidiaries,  we  would  be  subject  to 
taxes  payable  to  various  jurisdictions.    At  December 31,  2015,  the  amount  of  indefinitely  reinvested  earnings  was  approximately 
$2.2 billion.    If  all  of  these  indefinitely  reinvested  earnings  were  distributed,  we  would  be  subject  to  estimated  taxes  of  $200 million  to 
$250 million.

In  the  years  ended  December 31,  2015,  2014  and  2013,  we  recognized  income  of  $1 million,  $57 million  and  $23 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, 2015, if recognized, $405 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,  2016,  primarily  due  to  the  progression  of  open  audits  and  the  expiration  of  statutes  of  limitation.    However,  we  cannot 
reasonably estimate a range of potential changes in our existing liabilities for unrecognized tax benefits due to various uncertainties, such 
as the unresolved nature of various audits. 

Tax 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  the  U.S.,  Norway  and  Brazil,  which  are  mentioned 
below, are generally subject to examination for periods ranging from three to six years.  We have agreed to extensions beyond the statute 
of limitations in two major jurisdictions for up to 20 years.  Tax authorities in certain jurisdictions are examining our tax returns and in some 
cases have issued assessments.  We are defending our tax positions in those jurisdictions.  While we cannot predict or provide assurance 
as  to  the  timing  or  the  outcome  of  these  proceedings,  we  do  not  expect  the  ultimate  liability  to  have  a  material  adverse  effect  on  our 
consolidated statement of financial position or results of operations, although it may have a material adverse effect on our consolidated 
statement of cash flows. 

U.S. tax investigations—In January 2014, we received a draft assessment from the U.S. tax authorities related to our 2010 and 
2011  U.S.  federal  income  tax  returns.    The  significant  issue  raised  in  the  assessment  relates  to  transfer  pricing  for  certain  charters  of 
drilling rigs between our subsidiaries.  This issue, if successfully challenged, would result in net adjustments of approximately $290 million 
of additional taxes, excluding interest and penalties.  We believe our U.S. federal income tax returns are materially correct as filed, and we 
intend to continue to vigorously defend against all such claims to the contrary.  An unfavorable outcome on these adjustments could result 
in a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.  Furthermore, if the 
authorities  were  to  continue  to  pursue  these  positions  with  respect  to  subsequent  years  and  were  successful  in  such  assertions,  our 
effective  tax  rate  on  worldwide  earnings  with  respect  to  years  following  2011  could  increase  substantially,  and  could  have  a  material 
adverse effect on our consolidated results of operations or cash flows. 

Norway  tax  investigations  and  trial—Norwegian  civil  tax  and  criminal  authorities  are  investigating  various  transactions 
undertaken by our subsidiaries in 1999, 2001 and 2002 as well as the actions of certain employees of our former external tax advisors on 
these  transactions.    At  December 31,  2015,  outstanding  civil  tax  assessments  were  as  follows:  (a) NOK 412 million,  equivalent  to 
approximately $47 million, plus interest, related to a 2001 dividend payment and (b) NOK 43 million, equivalent to approximately $5 million, 
plus interest, related to certain foreign exchange deductions and dividend withholding tax.  On June 26, 2014, the Norwegian district court 
in Oslo ruled that our subsidiary was liable for the civil tax assessment of NOK 412 million, equivalent to approximately $47 million, but 
waived  all  penalties  and  interest.    On  September 12,  2014,  we  appealed  the  ruling.    We  intend  to  take  all  other  appropriate  action  to 
continue to support our position that our Norwegian tax returns are materially correct as filed.

In  June 2011,  the  Norwegian  authorities  issued  criminal  indictments  against  two of  our  subsidiaries  alleging  misleading  or 
incomplete disclosures in Norwegian tax returns for the years 1999 through 2002, as well as inaccuracies in Norwegian statutory financial 
statements  for  the  years  ended  December 31,  1996  through  2001.    The  Norwegian  authorities  subsequently  extended  a  criminal 
indictment against a third subsidiary in April 2012.  The Norwegian authorities also issued criminal indictments against two employees of 
our former external tax advisors related to the disclosures in our tax returns, and our former external Norwegian tax attorney related to 
certain of our restructuring transactions and the 2001 dividend payment.  On July 2, 2014, the District Court acquitted all subsidiaries and 
the  employees  of  our  former  external  tax  advisors  and  our  former  external  Norwegian  tax  attorney.    On  July 16,  2014,  the  Norwegian 
authorities filed appeals on three criminal charges but formally dropped all claims related to two criminal charges.  At December 31, 2015, 
the  outstanding  criminal  charges  were  with  respect  to  the  following  matters:  (a) disclosures  in  our  Norwegian  tax  returns  related  to  a 
dividend  payment  in  2001,  (b) disclosures  in  our  Norwegian  tax  returns  related  to  an  intercompany  rig  sale  in  1999  and  (c) certain 
inaccuracies  in  Norwegian  statutory  financial  statements  for  the  years  ended  December 31,  1996  through  2001.    We  believe  our 
Norwegian tax returns are materially correct as filed, and we intend to continue to vigorously contest any assertions to the contrary by the 
Norwegian civil and criminal authorities in connection with the various transactions being investigated.  An unfavorable outcome on the 
Norwegian civil and criminal tax matters could result in a material adverse effect on our consolidated statement of financial position, results 
of operations or cash flows.  See Note 25—Subsequent Events. 

Brazil  tax  investigations—Certain  of  our  Brazilian  income  tax  returns  for  the  years  2000  through  2004  are  currently  under 
examination.    In  December 2005,  the  Brazilian  tax  authorities  issued  an  aggregate  tax  assessment  of  BRL 762 million,  equivalent  to 
approximately  $192 million,  including  penalties  and  interest.    On  January 25,  2008,  we  filed  a  protest  letter  with  the  Brazilian  tax 
authorities, and we are currently engaged in the appeals process.  On May 19, 2014, with respect to our Brazilian income tax returns for 
the years 2009 and 2010, the Brazilian tax authorities issued an aggregate tax assessment of BRL 132 million, equivalent to approximately 
$33 million, including penalties and interest.  On June 18, 2014, we filed a protest letter with the Brazilian tax authorities.  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.

Standard jackup and swamp barge contract drilling services 

Overview—In September 2012, in connection with our efforts to dispose of non-strategic assets and to reduce our exposure to 
low-specification drilling units, we committed to a plan to discontinue operations associated with the standard jackup and swamp barge 
asset groups, components of our contract drilling services operating segment. 

Impairments—In the year ended December 31, 2013, we recognized an aggregate loss of $14 million ($0.04 per diluted share), 
which  had  no  tax  effect,  associated  with  the  impairment  of  the  standard  jackups  GSF Rig 127  and  GSF Rig 134.    We  measured  the 
impairment of the drilling units and related equipment as the amount by which the carrying amounts exceeded the estimated fair values 
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 a binding sale and purchase agreement for the drilling units and related equipment. 

Sale  transactions  with  Shelf Drilling—In  November 2012,  we  completed  the  sale  of  38 drilling  units  to  Shelf Drilling 
Holdings, Ltd. (“Shelf Drilling”).  A portion of the proceeds from the sale were in the form of perpetual preference shares that had a stated 
value of $195 million.  In June 2013, we sold the preference shares to an unaffiliated party for cash proceeds of $185 million and, in the 
year ended December 31, 2013, we recognized a loss of $10 million ($0.03 per diluted share), recorded in other expense, net, which had 
no tax effect, associated with the sale of the preference shares. 

For a transition period following the completion of the sale transactions, we agreed to continue to operate a substantial portion of 
the standard jackups under operating agreements with Shelf Drilling and to provide certain other transition services to Shelf Drilling.  Under 
the operating agreements, we agreed to remit the collections from our customers under the associated drilling contracts to Shelf Drilling, 
and  Shelf Drilling  agreed  to  reimburse  us  for  our  direct  costs  and  expenses  incurred while  operating  the  standard  jackups  on  behalf  of 
Shelf Drilling with certain exceptions.   Amounts  due to Shelf Drilling under the operating agreements and transition services agreement 
may be contractually offset against amounts due from Shelf Drilling.  The costs to us for providing such operating and transition services, 
including allocated indirect costs, exceeded the amounts we received from Shelf Drilling for providing such services. 

Under the operating agreements, we agreed to operate the standard jackups on behalf of Shelf Drilling for periods ranging from 
nine months to 27 months, until expiration or novation of the underlying drilling contracts by Shelf Drilling, the last of which was completed 
in  January 2015.    Until  the  expiration  or  novation  of  such  drilling  contracts,  we  retained  possession  of  the  materials  and  supplies 
associated with the standard jackups that we operated under the operating agreements.  In the years ended December 31, 2015, 2014 
and 2013, we received cash proceeds of $3 million, $25 million and $64 million, respectively, associated with the sale of equipment and 
materials and supplies to Shelf Drilling upon expiration of the drilling contracts.  In the year ended December 31, 2013, we recognized a 
net gain of $11 million ($0.03 per diluted share), which had no tax effect, associated with the sale of equipment and materials and supplies 
to Shelf Drilling upon expiration or novation of the drilling contracts. 

For a period through November 2015, we agreed to provide to Shelf Drilling up to $125 million of financial support by maintaining 
letters of credit, surety bonds and guarantees for various contract bidding and performance activities associated with the drilling units sold 
to Shelf Drilling and in effect at the closing of the sale transactions.  In November 2015, our commitment to provide such financial support 
expired, and at December  31, 2015, we had no remaining letters of credit outstanding in support of drilling units sold to Shelf Drilling.  At 
December 31,  2014,  we  had  $91 million  of  outstanding  letters  of  credit,  issued  under  our  committed  and  uncommitted  credit  lines,  in 
support of drilling units sold to Shelf Drilling.  See Note 14—Commitments and Contingencies. 

Other dispositions—During the year ended December 31, 2013, we completed the sale of the standard jackups D.R. Stewart, 
GSF Adriatic VIII, GSF Rig 127, GSF Rig 134, Interocean III, Trident IV-A and Trident VI, along with related equipment.  In the year ended 
December 31,  2013,  in  connection  with  the  disposal  of  these  assets,  we  received  aggregate  net  cash  proceeds  of  $140 million  and 
recognized  an  aggregate  net  gain  of  $44 million  ($0.12 per  diluted  share),  which  had  no  tax  effect.    In  the  years  ended  December 31, 
2015,  2014  and  2013,  we  recognized  an  aggregate  net  gain  of  $1 million  and  $2 million  and  an  aggregate  net  loss  of  $1 million, 
respectively, associated with the disposal of assets unrelated to rig sales. 

Drilling management services 

In February 2014, in connection with our efforts to discontinue non-strategic operations, we completed the sale of ADTI, which 
performs drilling management services in the North Sea.  As a result of the sale, we reclassified the results of operations of our drilling 
management services operating segment to discontinued operations for all periods presented.  In the year ended December 31, 2014, we 
received  net  cash  proceeds  of  $10 million  and  recognized  a  net  loss  of  $12 million  ($0.03 per  diluted  share),  which  had  no  tax  effect, 
associated with the sale of the drilling management services business.  We agreed to provide a $15 million working capital line of credit to 
the buyer through March 2016.  At December 31, 2014, ADTI owed to us borrowings of $15 million outstanding under the working capital 
line of credit, recorded in other assets.  In May 2015, ADTI repaid the borrowings and terminated the credit agreement.

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,  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 debt to 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, 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 credit rating 
of our non-credit enhanced senior unsecured long-term debt (“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,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

we pay a facility fee on the daily unused amount of the underlying commitment which ranges from 0.15 percent to 0.35 percent depending 
on our Debt Rating.  Effective March 19, 2015, as a result of a reduction of our Debt Rating, the Five-Year Revolving Credit Facility Margin 
increased  to  1.75 percent  from  1.5 percent  and  the  facility  fee  increased  to  0.275 percent  from  0.225 percent.    At  December 31,  2015, 
based  on  our  Debt  Rating  on  that  date,  the  Five-Year  Revolving  Credit  Facility  Margin  was  1.75 percent  and  the  facility  fee  was 
0.275 percent.  At December 31, 2015, we had no borrowings outstanding or letters of credit issued, and we had $3.0 billion of available 
borrowing capacity under the Five-Year Revolving Credit Facility. 

4.95% Senior  Notes  and  6.50% Senior  Notes—In  September 2010,  we  issued  $1.1 billion  aggregate  principal  amount  of 
4.95% Senior Notes due November 2015 (the “4.95% Senior Notes”) and $900 million aggregate principal amount of 6.50% Senior Notes 
due November 2020 (the “6.50% Senior Notes,” and together with the 4.95% Senior Notes, the “2010 Senior Notes”).  We are required to 
pay interest on the 2010 Senior Notes on May 15 and November 15 of each year, beginning November 15, 2010.  We may redeem some 
or all of the 2010 Senior Notes at any time at a redemption price equal to 100 percent of the principal amount plus accrued and unpaid 
interest, if any, and a make-whole premium.  The indenture pursuant to which the 2010 Senior Notes were issued contains restrictions on 
creating liens, engaging in sale/leaseback transactions and engaging in merger, consolidation or reorganization transactions. 

On November 17, 2014, we redeemed an aggregate principal amount of $207 million of the outstanding 4.95% Senior Notes with 
an aggregate payment of $216 million and we recognized a loss of $9 million associated with the partial redemption.  On July 30, 2015, we 
redeemed  the  remaining  aggregate  principal  amount  of  $893 million  of  the  outstanding  4.95% Senior  Notes  with  an  aggregate  cash 
payment of $904 million, and in the year ended December 31, 2015, we recognized a loss of $10 million associated with the retirement.  At 
December 31, 2015 and 2014, the aggregate outstanding principal amount of the 6.50% Senior Notes was $900 million. 

5.05% Senior  Notes,  6.375% Senior  Notes  and  7.35% Senior  Notes—In  December 2011,  we  issued  $1.0 billion  aggregate 
principal  amount  of  5.05% Senior  Notes  due  December 2016  (the  “5.05% Senior  Notes”),  $1.2 billion  aggregate  principal  amount  of 
6.375% Senior  Notes  due  December 2021  (the  “6.375% Senior  Notes”)  and  $300 million  aggregate  principal  amount  of  7.35% Senior 
Notes  due  December 2041  (the  “7.35% Senior  Notes,”  and  collectively  with  the  5.05% Senior  Notes  and  the  6.375% Senior  Notes,  the 
“2011 Senior  Notes”).    The  interest  rates  for  the  notes  are  subject  to  adjustment  from  time  to  time  upon  a  change  to  our  Debt  Rating.  
Effective June 15 and December 15, 2015, as a result of reductions of our Debt Rating, the interest rates on the 5.05% Senior Notes, the 
6.375% Senior Notes and the 7.35% Senior Notes increased by an incremental 0.5 percent and 0.25 percent, respectively, from the stated 
rate to 5.80 percent, 7.125 percent and 8.10 percent, respectively.  The indenture pursuant to which the 2011 Senior Notes were issued 
contains restrictions on creating  liens, engaging  in sale/leaseback transactions and engaging in  merger, consolidation or reorganization 
transactions.  We may redeem some or all of the 2011 Senior Notes at any time at a redemption price equal to 100 percent of the principal 
amount plus accrued and unpaid interest, if any, and a make-whole premium. 

In the year ended December 31, 2015, we repurchased an aggregate principal amount of $25 million of the 5.05% Senior Notes 
and $50 million of the 6.375% Senior Notes with aggregate cash payments of $25 million and $40 million, respectively, and recognized a 
gain of less than $1 million and $10 million, respectively, associated with the retirement of debt.  At December 31, 2015, the  aggregate 
outstanding  principal  amount  of  the  5.05% Senior  Notes,  the  6.375% Senior  Notes  and  the  7.35% Senior  Notes  was  $975 million, 
$1.2 billion and $300 million, respectively. 

2.5%  Senior  Notes  and  3.8%  Senior  Notes—In  September 2012,  we  issued  $750 million  aggregate  principal  amount  of 
2.5% Senior Notes due October 2017 (the “2.5% Senior Notes”) and $750 million aggregate principal amount of 3.8% Senior Notes due 
October 2022  (the  “3.8% Senior  Notes,”  and  together  with  the  2.5% Senior  Notes,  the  “2012 Senior  Notes”).    The  interest  rates  for  the 
notes are subject to adjustment from time to time upon a change to our Debt Rating.  Effective April 15, 2015, as a result of a reduction of 
our  Debt  Rating,  the  interest  rates  on  the  2.5% Senior  Notes  and  the  3.8% Senior  Notes  increased  0.5 percent  from  the  stated  rate  to 
3.0 percent and 4.3 percent, respectively.  The indenture pursuant to which the 2012 Senior Notes were issued contains restrictions on 
creating  liens,  engaging  in  sale/leaseback  transactions  and  engaging  in  merger,  consolidation  or  reorganization  transactions.    We  may 
redeem  some  or  all  of  the  2012 Senior  Notes  at  any  time  prior  to  maturity  at  a  redemption  price  equal  to  100 percent  of  the  principal 
amount plus accrued and unpaid interest, if any, together with a make-whole premium unless, in the case of the 3.8% Senior Notes, such 
redemption occurs on or after July 15, 2022, in which case no such make-whole premium will apply. 

In the year ended December 31, 2015, we repurchased an aggregate principal amount of $180 million of the 2.5% Senior Notes 
and $16 million of the 3.8% Senior Notes with an aggregate cash payment of $170 million and $11 million, respectively, and recognized an 
aggregate gain of $9 million and $5 million, respectively, associated with the retirement of debt.  At December 31, 2015, the aggregate 
outstanding principal amount of the 2.5% Senior Notes and the 3.8% Senior Notes was $570 million and $734 million, respectively. 

5.25% Senior  Notes,  6.00% Senior  Notes  and  6.80% Senior  Notes—In  December 2007,  we  issued  $500 million  aggregate 
principal  amount  of  5.25% Senior  Notes  due  March 2013  (the  “5.25% Senior  Notes”),  $1.0 billion  aggregate  principal  amount  of 
6.00% Senior Notes due March 2018 (the “6.00% Senior Notes”) and $1.0 billion aggregate principal amount of 6.80% Senior Notes due 
March 2038 (the “6.80% Senior Notes”).  The indenture pursuant to which the notes were issued contains restrictions on creating liens, 
engaging in sale/leaseback transactions and engaging in merger, consolidation or reorganization transactions.  We may redeem some or 
all of the notes at any time, at a redemption price equal to 100 percent of the principal amount plus accrued and unpaid interest, if any, and 
a make-whole premium.

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

In the year ended December 31, 2015, we repurchased an aggregate principal amount of $211 million of the 6.00% Senior Notes 
with an aggregate cash payment of $205 million and recognized an aggregate gain of $5 million associated with the retirement of debt.  On 
March 15, 2013, the stated maturity date of the 5.25% Senior Notes, we repaid the outstanding $500 million aggregate principal amount of 
the  5.25% Senior  Notes.    At  December 31,  2015,  the  aggregate  outstanding  principal  amount  of  the  6.00% Senior  Notes  and  the 
6.80% Senior Notes was $789 million and $1.0 billion, respectively. 

Eksportfinans  Loans—We  have  borrowings  under  the  Loan  Agreement  dated  September 12,  2008  (“Eksportfinans  Loan A”) 
and  under  the  Loan  Agreement  dated  November 18,  2008  (“Eksportfinans  Loan B,”  and  together  with  Eksportfinans  Loan A,  the 
“Eksportfinans  Loans”).    The  Eksportfinans  Loans  bear  interest  at  a  fixed  rate  of  4.15 percent  and  require  semi-annual  installments  of 
principal  and  interest  through  September 2017  and  January 2018  for  Eksportfinans  Loan A  and  Eksportfinans  Loan B,  respectively.    At 
December 31,  2015  and  2014,  the  aggregate  principal  amount  outstanding  under  the  Eksportfinans  Loans  was  NOK 1.9 billion  and 
NOK 2.8 billion, equivalent to approximately $217 million and $370 million, respectively. 

The Eksportfinans Loans require collateral to be held by a financial institution through expiration (the “Eksportfinans Restricted 
Cash  Investments”).    The  Eksportfinans  Restricted  Cash  Investments  bear  interest  at  a  fixed  rate  of  4.15 percent  with  semi-annual 
installments that correspond with those of the Eksportfinans Loans.  At December 31, 2015 and 2014, the aggregate principal amount of 
the  Eksportfinans  Restricted  Cash  Investments  was  NOK 1.9 billion  and  NOK 2.8 billion,  equivalent  to  approximately  $217 million  and 
$370 million, respectively. 

7.375% Senior Notes—In March 2002, we issued $247 million principal amount of our 7.375% Senior Notes due April 2018 (the 
“7.375% Senior Notes”).  The indenture pursuant to which the 7.375% Senior Notes were issued contains restrictions on creating  liens, 
engaging  in  sale/leaseback  transactions  and  engaging  in  merger,  consolidation  or  reorganization  transactions.    In  the  year  ended 
December 31, 2015, we repurchased an aggregate principal amount of $10 million of the 7.375% Senior Notes with an aggregate cash 
payment of $9 million and recognized an aggregate gain of $1 million associated with the retirement of debt.  At December 31, 2015, the 
aggregate outstanding principal amount of the 7.375% Senior Notes was $236 million. 

7.45% Notes  and  8% Debentures—In  April 1997,  a  predecessor  of  Transocean Inc.  issued  $100 million  aggregate  principal 
amount of 7.45% Notes due April 2027 (the “7.45% Notes”) and $200 million aggregate principal amount of 8% Debentures due April 2027 
(the “8% Debentures”).  The indenture pursuant to which the 7.45% Notes and the 8% Debentures were issued contains restrictions on 
creating  liens,  engaging  in  sale/leaseback  transactions  and  engaging  in  merger,  consolidation  or  reorganization  transactions.    The 
7.45% Notes  and  the  8% Debentures  are  redeemable  at  any  time  at  our  option  subject  to  a  make-whole  premium.    In  the  year  ended 
December 31,  2015,  we  repurchased  an  aggregate  principal  amount  of  $4 million  of  the  7.45% Senior  Notes  with  an  aggregate  cash 
payment of $3 million and recognized an aggregate gain of $1 million associated with the retirement of debt.  At December 31, 2015, the 
aggregate outstanding principal amount of the 7.45% Notes and the 8% Debentures was $96 million and $57 million, respectively. 

7% Notes—One of our wholly-owned subsidiaries is the obligor of the 7% Notes due 2028 (the “7% Notes”), and we have not 
guaranteed this obligation.  The indenture related to the 7% Notes contains limitations on creating liens and sale/leaseback transactions.  
The obligor may redeem the 7% Notes in whole or in part at a price equal to 100 percent of the principal amount plus accrued and unpaid 
interest, if any, and a make-whole premium.  At December 31, 2015, the outstanding principal amount of the 7% Notes was $300 million. 

Capital lease contract—In August 2009, we accepted delivery of Petrobras 10000, an asset held under capital lease, and we 
recorded $716 million to property and equipment, net and a corresponding increase to long-term debt.  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.  See Note 14—Commitments and Contingencies. 

7.5% Notes—In April 2001, we issued $600 million aggregate principal amount of 7.5% Notes due April 2031 (the “7.5% Notes”).  
The indenture pursuant to which the notes were issued contains restrictions on creating liens, engaging in sale/leaseback transactions and 
engaging in merger, consolidation or reorganization transactions.  In the year ended December 31, 2015, we repurchased an aggregate 
principal  amount  of  $7 million  of  the  7.5% Senior  Notes  with  an  aggregate  payment  of  $5 million  and  recognized  an  aggregate  gain  of 
$2 million  associated  with  the  retirement  of  debt.    At  December 31,  2015,  the  outstanding  principal  amount  of  the  7.5% Notes  was 
$593 million. 

ADDCL Credit Facility—ADDCL had a $704 million senior secured credit facility, established under a bank credit agreement 
dated  June 2,  2008  that  was  scheduled  to  expire  in  December 2017  (the  “ADDCL  Credit  Facility”),  for  which  one of  our  subsidiaries 
provided the portion of the commitment for the facility.  In February 2014, we made a cash payment of $614 million to repay the borrowings 
outstanding under the ADDCL Credit Facility, $451 million of which was paid to one of our subsidiaries and eliminated in consolidation.  
Upon repayment of all borrowings, we terminated the bank credit agreement under which the credit facility was established. 

1.50% Series C  Convertible  Senior  Notes—In  December 2007,  we  issued  $2.2 billion  aggregate  principal  amount  of  the 
1.50% Series C Convertible Senior Notes due December 2037 (the “Convertible Senior Notes”).  On December 14, 2012, certain holders 
of the Series C Convertible Senior Notes exercised their option to require us to repurchase all or any part of such holders’ notes, and as a 
result,  we  were  required  to  repurchase  an  aggregate  principal  amount  of  $1.7 billion  of  the  Series C  Convertible  Senior  Notes  for  an 
aggregate  cash  payment  of  $1.7 billion.    In  February 2013,  we  redeemed  the  remaining  $62 million  aggregate  principal  amount  of  the 
Series C Convertible Senior Notes for an aggregate cash payment of $62 million.

Callable Bonds—We were the obligor for the FRN Aker Drilling ASA Senior Unsecured Callable Bond Issue 2011/2016 and the 
11% Aker Drilling ASA Senior Unsecured Callable Bond Issue 2011/2016 (together, the “Callable Bonds”), which were publicly traded on 
the  Oslo  Stock  Exchange.    In  March 2013,  we  made  an  aggregate  cash  payment  of  NOK 1,567 million,  equivalent  to  $273 million,  to 
redeem  the  aggregate  outstanding  principal  amount  of  NOK 1,500 million,  equivalent  to  $262 million.    In  the  year  ended  December 31, 
2013, we recognized a loss of $1 million associated with the retirement of debt. 

TPDI Credit Facility—Transocean Pacific Drilling Inc. (“TPDI”), our wholly owned subsidiary, had a $1.265 billion secured credit 
facility, established under a bank credit agreement dated October 28, 2008, that was scheduled to expire in March 2015 (the “TPDI Credit 
Facility”), for which one of our subsidiaries provided a portion of the commitment for the facility.  In June 2013, we made a cash payment of 
$735 million to repay the borrowings outstanding under the TPDI Credit Facility, $367 million of which was paid to one of our subsidiaries 
and eliminated in consolidation.  Upon repayment of all borrowings, we terminated the bank credit agreement under which the credit facility 
was established and the related security agreement.  In the year ended December 31, 2013, we recognized a loss of $1 million associated 
with the retirement of debt. 

Note 12—Derivatives and Hedging 

Derivatives designated  as  hedging  instruments—During  the year  ended  December 31,  2014,  we  entered  into  interest  rate 
swaps, which are designated and qualify as a fair value hedge, to reduce our exposure to changes in the fair value of the 6.0% Senior 
Notes due March 2018 and the 6.5% Senior Notes due November 2020.  The interest rate swaps have aggregate notional amounts equal 
to the corresponding face values of the hedged instruments and have stated maturities that coincide with those of the hedged instruments.  
We have determined that the hedging relationships qualify for, and we have applied, the shortcut method of accounting under which the 
interest  rate  swaps  are  considered  to  have  no  ineffectiveness  and  no  ongoing  assessment  of  effectiveness  is  required.    Accordingly, 
changes  in  the  fair  value  of  the  interest  rate  swaps  recognized  in  interest  expense  offset  the  changes  in  the  fair  value  of  the  hedged 
fixed-rate notes.  During the year ended December 31, 2015, we terminated the interest rate swaps previously designated as a fair value 
hedge of the 6.5% Senior Notes, and we received an aggregate net cash payment of $24 million in connection with the settlement. 

At December 31, 2015, the aggregate notional amounts and the weighted average interest rates associated with our derivatives 

designated as hedging instruments were as follows (in millions, except weighted average rates):

At December 31, 2015 and 2014, the aggregate carrying amount of our derivatives designated as fair value hedges, measured at 
fair  value  and  excluding  accrued  interest,  was  $2 million  and  $11 million,  respectively,  recorded  in  other  assets.    See  Note 23—
Subsequent Events. 

 We previously had interest rate swaps, which were designated and qualified as a cash flow hedge, to reduce the variability of 
cash  interest  payments  associated  with  the  variable-rate  borrowings  under  the  TPDI  Credit  Facility.    In  June 2013,  we  repaid  the 
borrowings  under  the  TPDI  Credit  Facility,  and  we  terminated  these  interest  rate  swaps.    In  the  year  ended  December 31,  2013,  we 
recognized a loss of $4 million, recorded in interest expense, net of capitalized amounts, associated with the effective portion of the cash 
flow hedges.  In connection with the termination, we recognized a loss of $14 million, recorded in other, net, including $9 million that we 
reclassified from accumulated other comprehensive loss, and we made a net cash payment of $22 million. 

Additionally, we had cross-currency interest rate swaps, which were designated and qualified as a cash flow hedge, to reduce 
the variability of the cash interest payments and the final cash principal payment associated with the Callable Bonds resulting from the 
changes in the U.S. dollar to Norwegian krone exchange rate.  In March 2013, in connection with our redemption of the Callable Bonds, we 
terminated these cross-currency interest rate swaps and the related security agreement.  As a result of the termination, in the year ended 
December 31, 2013, we made a cash payment of $128 million, we received a cash payment of NOK 705 million, which we applied to the 
redemption of the Callable Bonds, and we reclassified $5 million from accumulated other comprehensive loss to other expense, net.

Overview—In connection with actions taken by us in the year ended December 31, 2015, benefits under all of our remaining 
U.S. defined benefit pension plans had ceased accruing or were scheduled to cease accruing  by March 31, 2016.  We will continue to 
maintain the respective pension obligations under such plans until they have been fully satisfied.  As of December 31, 2015, we maintained 
one funded qualified benefit plan, which primarily covers employees on the U.S. payroll that work outside of the U.S., that will cease to 
accrue benefits, effective March 31, 2016.  Effective January 1, 2015, we formalized amendments to cease accruing benefits under our 
funded qualified defined benefit pension plan, which previously covered substantially all of our U.S. employees, and a supplemental benefit 
plan,  which  previously  provided  certain  eligible  employees  with  benefits  in  excess  of  those  allowed  under  the  funded  qualified  defined 
benefit pension plan.  We also maintain one funded and two unfunded defined benefit plans that had previously ceased accruing benefits.  
We refer to these plans, collectively, as the “U.S. Plans.” 

As  of  December 31,  2015,  we  maintain  a  defined  benefit  plan  in  the  U.K.  (the  “U.K. Plan”),  which  covers  certain  current  and 
former employees in the U.K. (see Note 25—Subsequent Events).  We also maintain six funded and two unfunded defined benefit plans, 
primarily group  pension  schemes with  life insurance companies, which  cover certain eligible Norway employees  and former employees 
(the “Norway Plans”).  Additionally, we maintain certain unfunded defined benefit plans that provide retirement and severance benefits for 
certain  eligible  Nigerian  and  Indonesian  employees.    We  also  maintained  an  end-of-service  benefit  plan  for  certain  eligible  Egyptian 
employees, for which we have satisfied all obligations in the year ended December 31, 2015.  We refer to the U.K. Plan, the Norway Plans 
and the plans in Nigeria, Indonesia and Egypt, 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  have  several 
unfunded contributory and noncontributory other postretirement employee benefit plans (the “OPEB Plans”) covering substantially all of our 
U.S.  employees.    On  August 25,  2015,  we  announced  amendments  to  our  OPEB Plans  that  provide  for  declining  benefits  to  eligible 
participants during a phase-out period ending December 31, 2025.

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

As  of  December 31,  2015  and  2014,  the  weighted-average  target  and  actual  allocations  of  the  investments  for  our  funded 

Transocean Plans were as follows:

The  U.S. Plans  and  the  U.K. Plan  invest  primarily  in  passively  managed  funds  that  reference  market  indices.    The  funded 
Norway Plans are subject to contractual terms under selected insurance programs.  Each plan’s investment managers have discretion to 
select the securities held within each asset category.  Given this discretion, the managers may occasionally invest in our debt or equity 
securities, and may hold either long or short positions in such securities.  As the plan investment managers are required to maintain well 
diversified portfolios, the actual investment in our securities would be immaterial relative to asset categories and the overall plan assets.

In September and December 2014, we recognized settlement and curtailment charges for two of our unfunded Non-U.S. Plans in 

Nigeria and Egypt associated with certain employee terminations. 

In the years ended December 31, 2015, 2014 and 2013, for the OPEB Plans, the combined components of net periodic benefit 
costs,  including  service  cost,  interest  cost,  recognized  net  actuarial  losses,  prior  service  cost  amortization,  curtailments  and  special 
termination benefits were $(1) million, $2 million and $3 million, respectively. 

The  following  table  presents  the  amounts  in  accumulated  other  comprehensive  income  (loss),  before  tax,  that  have  not  been 

recognized as components of net periodic benefit costs (in millions):

Funding  contributions—In  the  years  ended  December 31,  2015,  2014  and  2013,  we  made  an  aggregate  contribution  of 
$39 million,  $101 million  and  $115 million,  respectively,  to  the  Transocean Plans  and  the  OPEB  Plans  using  our  cash  flows  from 
operations.  In the year ending December 31, 2016, we expect to contribute $52 million to the Transocean Plans, and we expect to fund 
benefit payments of approximately $3 million for the OPEB Plans as costs are incurred.

Defined contribution plans 

At December 31, 2015, we sponsored three defined contribution plans, including (1) a qualified defined contribution savings plan 
covering certain employees working  in the U.S. (the “U.S. Savings Plan”), (2) a supplemental defined contribution plan  covering certain 
eligible employees working in the U.S. (the “U.S. Supplemental Savings Plan”) and (3) a defined contribution savings plan covering certain 
employees  working  outside  the  U.S.  (the  “Non-U.S. Savings  Plan”).    In  the  years  ended  December 31,  2015,  2014  and  2013,  we 
recognized expense of $89 million, $84 million and $88 million, respectively, related to our defined contribution plans. 

For the U.S. Savings Plan, effective January 1, 2015, we amended the plan to increase our matching contribution to be up to 
10.0 percent of each participant’s base salary based on the participant’s contribution to the plan.  In the years ended December 31, 2014 
and 2013, we made matching contributions of up to 6.0 percent of each participant’s base salary based on the participant’s contribution to 
the plan.  The U.S. Supplemental Savings Plan, effective January 1, 2015, provides eligible employees with benefits in excess of those 
allowed under the U.S. Savings Plan. 

For the Non-U.S. Savings Plan, in addition to a matching contribution of up to 6.0 percent of each participant’s base salary based 
on the participant’s contribution to the plans, we contribute between 4.5 percent and 6.5 percent of each participant’s base salary, based 
on the participant’s years of eligible service. 

Note 14—Commitments and Contingencies 

Lease obligations 

We have operating lease obligations expiring at various dates, principally for real estate, office space and office equipment.  In 
the years ended December 31, 2015, 2014 and 2013, our rental expense for all operating leases, including operating leases with terms of 
less than one year, was approximately $72 million, $95 million and $128 million, respectively. 

We also have a capital lease obligation, which is due to expire in August 2029.  In the years ended December 31, 2015, 2014 
and  2013,  depreciation  expense  associated  with  Petrobras 10000,  the  asset  held  under  capital  lease,  was  $23 million,  $21 million  and 
$20 million, respectively. 

At  December 31,  2015  and  2014,  the  aggregate  carrying  amount  of  this  asset  held  under  capital  lease  was  as  follows

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  as  a  result  of  settlements  with  the  U.S.  Department  of  Justice  (the  “DOJ”),  BP,  the  states  of  Alabama,  Florida,  Louisiana, 
Mississippi, and Texas (collectively, the “States”) and the Plaintiffs’ Steering Committee (the “PSC”). 

During  the  year  ended  December 31,  2015,  in  connection  with  the  settlements,  as  further  described  below,  we  adjusted  our 
assets and liabilities associated with contingencies resulting from the Macondo well incident.  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 made such adjustments with corresponding entries to increase accounts receivable 
by $663 million and decrease other current liabilities by $125 million.  In the year ended December 31, 2015, we received cash proceeds of 
$663 million,  including  $125 million  from  BP  and  $538 million  from  insurance,  associated  with  reimbursement  for  or  recoveries  of 
previously incurred losses. 

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, 2015 and 2014, 
the  liability  for  estimated  loss  contingencies  that  we  believe  are  probable  and  for  which  a  reasonable  estimate  can  be  made  was 
$250 million and $426 million, respectively, recorded in other current liabilities.  We believe the remaining most notable claims against us 
arising  from  the  Macondo well  incident  are  the  potential  settlement  class  opt-outs  from  the  PSC Settlement  Agreement,  as  described 
below.  The liability for estimated loss contingencies at December 31, 2015, included, among others, the amount we have agreed to pay as 
a result of our settlement with the PSC (see “—PSC Settlement Agreement” below), which is subject to approval by the MDL Court.  The 
remaining litigation could result in certain loss contingencies that we believe are reasonably possible.  Although we have not recognized a 
liability for such loss contingencies, these contingencies could result in liabilities that we ultimately recognize. 

We  recognize  an  asset  associated  with  the  portion  of  our  estimated  losses  that  we  believe  is  probable  of  recovery  from 
insurance  and  for  which  we  had  received  from  underwriters’  confirmation  of  expected  payment.    At  December 31,  2014,  the  insurance 
recoverable  asset  was  $10 million,  recorded  in  other  assets.    Although  we  have  available  policy  limits  that  could  result  in  additional 
amounts recoverable from insurance, recovery of such additional amounts is not probable and we are not currently able to estimate such 
amounts (see “—Insurance coverage”).  Our estimates involve a significant amount of judgment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

We believe we have agreements that will resolve substantially all outstanding claims against us arising from the Macondo well 

incident through a series of settlements with the following parties: 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

U.S.  Department  of  Justice—Guilty  plea  agreement  (“Plea  Agreement”)  and  civil  consent decree  (“Consent Decree”),  entered  into  on 
January 3, 2013, provide for $1.4 billion in fines and penalties, payable in installments through February 2017, and require us to take a 
number of certain actions, including to enhance safety and environmental compliance when operating in U.S. waters, as further specified 
below. 

U.S. Environmental Protection Agency—Administrative agreement (the “EPA Agreement”), entered into on February 25, 2013, resolves 
all matters related to suspension, debarment and disqualification and requires us to comply with the Plea Agreement and Consent Decree 
and continue implementation of certain programs and undertake further actions as specified below.  Pursuant to the EPA Agreement, we 
must refrain from engaging in business relationships with persons or entities that are restricted from conducting business in the U.S. 

BP—Settlement  Agreement  (“BP  Settlement  Agreement”),  entered  into  on  May 20,  2015,  resolves  all  Macondo  litigation  and  claims 
between BP and us, commits BP to pay us $125 million, to indemnify us for compensatory damages from oil pollution, and provides for 
the mutual release of all claims, including claims by BP to be an unlimited additional insured under our insurance policies. 

Plaintiff Steering Committee—Settlement agreement (the “PSC Settlement Agreement”) filed with the MDL Court on May 29, 2015 and 
subject to approval by the MDL Court, obligates us to pay $212 million to private plaintiffs, businesses and local governments, and up to 
an additional $25 million for reimbursement of plaintiff attorneys’ fees in exchange for a release of claims brought by the PSC against us. 

The  States—Settlement  Agreement  (the  “States  Settlement  Agreement”),  effective  October 13,  2015,  obligates  us  to  make  a  cash 
payment of $35 million to the States in exchange for release of all claims arising from the Macondo well incident. 

Payments made pursuant to the Plea Agreement and Consent Decree are not deductible for tax purposes and may not be used 
as  a  basis  for  indemnity  or  reimbursement  from  BP  or  other  defendants  involved  in  the  Macondo  well  incident  litigation.    Further  detail 
regarding our settlement obligations and the restrictions that apply to us is provided below. 

Plea Agreement—Pursuant to 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.  The DOJ agreed, subject to the provisions of the Plea Agreement, not to further prosecute us for certain matters arising 
from the Macondo well incident.  We remain subject to probation through February 2018. 

We  also  agreed  to  make  an  aggregate  cash  payment  of  $400 million,  including  a  criminal  fine  of  $100 million  and  cash 
contributions of $150 million to the National Fish & Wildlife Foundation and $150 million to the National Academy of Sciences, payable in 
scheduled installments.  In the years ended December 31, 2015, 2014 and 2013, we made an aggregate cash payment of $60 million, 
$60 million and $160 million, respectively, in satisfaction of amounts due under the Plea Agreement.  At December 31, 2015 and 2014, the 
carrying amount of our liability for settlement obligations under the Plea Agreement was $120 million and $180 million, respectively.  At 
December 31, 2015, the aggregate future payments required under our outstanding settlement obligations under the Plea Agreement were 
$60 million in each of the years ending December 31, 2016 and 2017. 

Consent Decree—Pursuant to the Consent Decree, we agreed to pay $1.0 billion in  civil penalties, excluding interest.  In the 
years ended December 31, 2015, 2014 and 2013, we paid $204 million, $412 million and $404 million, respectively, including interest at a 
rate of 2.15 percent, in satisfaction of amounts due under the Consent Decree.  As of December 31, 2015, we have satisfied our required 
payments due under the Consent Decree.  At December 31, 2014, the amount due under the Consent Decree was $200 million, recorded 
in other current liabilities. 

Under  the  Consent Decree,  we  also  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 certain plans, reports and submissions and also requires 
us to make such submittals available publicly.  One of the required plans is a performance plan (the “Performance Plan”) that contains, 
among other things, interim milestones for actions in specified areas and schedules for reports required under the Consent Decree.  On 
January 2,  2014,  the  DOJ  approved  our  proposed  Performance  Plan.    Additionally,  in  compliance  with  the  requirements  of  the 
Consent Decree and upon approval by the DOJ, we have 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. 

Under the terms of the Consent Decree, the U.S. agreed not to sue Transocean Ltd. and certain of its subsidiaries for civil or 
administrative  penalties  for  the  Macondo well  incident  under  specified  provisions  of  the  CWA,  the  Outer  Continental  Shelf  Lands  Act 
(“OCSLA”), the Endangered Species Act, the Marine Mammal Protection Act, the National Marine Sanctuaries Act, the federal Oil and Gas 
Royalty  Management  Act,  the  Comprehensive  Environmental  Response,  Compensation  and  Liability  Act  (“CERCLA”),  the  Emergency 
Planning and Community Right-to-Know Act (“EPCRA”) and the Clean Air Act.  In addition, the Consent Decree resolved our appeal of the 
incidents of noncompliance under the OCSLA issued by the Bureau of Safety and Environmental Enforcement without any admission of 
liability by us. 

We may request termination of the Consent Decree after January 2, 2019, provided we meet certain conditions set forth in the 
Consent Decree.  The Consent Decree resolved the claim by the U.S. for civil penalties under the Clean Water Act.  The Consent Decree 
did  not  resolve  United  States’  claim  under  the  Oil Pollution  Act  (“OPA”)  for  natural  resource  damages  (“NRD”)  or  for  removal  costs.  

AR-88 

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

However,  BP  has  agreed  to  indemnify  us  for  NRD  and  most  removal  costs  as  further  discussed  under  “—BP Settlement  Agreement” 
below. 

EPA Agreement—On  February 25,  2013,  we  and  the  EPA  entered  into  the  EPA Agreement,  which  has  a  five-year  term.  
Subject to our compliance with the terms of the EPA Agreement, the EPA agreed that it will not suspend, debar or statutorily disqualify us 
and  will  lift  any  existing  suspension,  debarment  or  statutory  disqualification.    In  the  EPA Agreement,  we  agreed  to  comply  with  our 
obligations  under  the  Plea Agreement  and  the  Consent Decree  and  continue  the  implementation  of  certain  programs  and  systems 
designed  to  enhance  our  environmental  management  systems  and  improve  our  environmental  performance.    We  also  agreed  to  other 
specified actions, including the (i) scheduled revision of our environmental management system and maintenance of certain compliance 
and ethics programs; (ii) compliance with certain employment and contracting procedures; (iii) engagement of an independent compliance 
auditor  to,  among  other  things,  assess  and  report  to  the  EPA  on  our  compliance  with  the  terms  of  the  Plea Agreement,  the 
Consent Decree and the EPA Agreement and (iv) provision of reports and notices with respect to various matters, including those related 
to  compliance,  misconduct,  legal  proceedings,  audit  reports,  the  EPA Agreement,  the  Consent Decree  and  the  Plea Agreement.    The 
EPA Agreement prohibits us from entering into, extending or engaging in certain business relationships with individuals or entities that are 
debarred, suspended, proposed for debarment or similarly restricted. 

BP  Settlement  Agreement—On  May 20,  2015,  we  entered  into  a  settlement  agreement  with  BP  (the  “BP Settlement 
Agreement”).  We believe the BP Settlement Agreement resolves all Macondo well-related litigation between BP and us, and the indemnity 
BP has committed to provide will generally address claims by third parties, including claims for economic and property damages, economic 
loss and NRD.  However, the indemnity obligations do not extend to fines, penalties, or punitive damages.  The BP Settlement Agreement 
requires that: 

(cid:131) 

(cid:131) 

BP pay us $125 million, and we received such payment in July 2015,  as partial reimbursement of the  legal costs we have  incurred  in 
connection with the Macondo well incident;  
BP  indemnify  us  for  compensatory  damages,  including  all  natural  resource  damages  and  all  cleanup  and  removal  costs  for  oil  or 
pollutants originating from the Macondo well;  

(cid:131)  We indemnify BP for personal and bodily injury claims of our employees and for any future costs for the cleanup or removal of pollutants 

stored on the Deepwater Horizon vessel;  
BP  cease  efforts  to  recover  as  an  unlimited  additional  insured  under  our  insurance  policies,  and  be  bound  to  the  insurance 
reimbursement rulings related to the Macondo well incident;  
BP and we each release and withdraw all claims we have against each other arising from the Macondo well litigation; and  
Neither BP nor we make statements regarding gross negligence in the Macondo well incident. 

(cid:131) 

(cid:131) 
(cid:131) 

BP  settlement  with  the  U.S.  and  the  States—On  July 2,  2015,  BP  announced  it  had  reached  an  agreement  in  principle  to 
settle claims with the U.S.; the States and local governments in the U.S. Gulf region.  On October 5, 2015, BP, the U.S. and the States 
filed a proposed consent decree that is subject to approval by the MDL Court.  If approved, the agreement will resolve the claims of the 
U.S.  and  the  States  for  NRD  under  OPA.    This  agreement,  together  with  the  NRD  indemnity  obligations  by  BP  pursuant  to  the 
BP Settlement Agreement, largely eliminates potential liability we may  have arising from NRD claims.  Accordingly, we believe that our 
likelihood of loss resulting from any NRD claims is remote. 

PSC Settlement Agreement—On May 29, 2015, together with the PSC, we filed a settlement agreement (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) private plaintiffs, 
businesses,  and  local  governments  who  could  have  asserted  punitive  damages  claims  against  us  under  general  maritime  law  (the 
“Punitive  Damages  Class”);  and  (2) private  plaintiffs  who  previously  settled  economic  damages  claims  against  BP  and  were  assigned 
certain claims BP had made against us (the “Assigned Claims Class”).  A court-appointed neutral representative established the allocation 
of the settlement payment to be 72.8 percent paid to the Punitive Damages Class and 27.2 percent paid to the Assigned Claims Class.  In 
exchange  for  these  payments,  each  of  the  classes  agreed  to  release  all  respective  claims  it  has  against  us.    Members  of  the  Punitive 
Damages Class may opt out of the PSC Settlement Agreement and pursue punitive damages claims against us, but we may terminate the 
PSC Settlement Agreement if the number of opt outs exceeds a specified threshold amount.  In August 2015, we made a cash deposit of 
$212 million  into  an  escrow  account  pending  approval  of  the  settlement  by  the  MDL Court.    At  December 31,  2015,  the  balance  of  the 
escrow account was $212 million, recorded in other current assets. 

States settlement agreement—Effective October 13, 2015, we finalized a  settlement agreement with the States, pursuant to 
which the States agreed to release all of their claims against us arising from the Macondo well incident.  On October 22, 2015, we made an 
aggregate cash payment of $35 million to the States. 

Multidistrict  litigation  proceeding—Most  Macondo well-related  claims  against  us  have  been  resolved  under  various 
settlements,  described  above.    There  are,  however,  still  pending  claims  by  potential  opt-outs  from  the  settlement  with  the  PSC  and  a 
number  of  other  parties.    As  of  December 31,  2015,  the  MDL Court  has  completed  the  liability  phase  trial,  and  additional  litigation  and 
appeals continue. 

The Phase One trial in 2013 addressed fault for the Macondo blowout and resulting oil spill.  The MDL Court’s September 2014 
Phase One ruling concluded that BP was grossly negligent and reckless and 67 percent at fault for the blowout, explosion, and spill; that 

AR-89 

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

we  were  negligent  and  30 percent  at  fault;  and  that  Halliburton Company  (“Halliburton”)  was  negligent  and  three percent  at  fault.    The 
finding  that  we  were  negligent,  but  not  grossly  negligent,  meant  that,  subject  to  a  successful  appeal,  we  would  not  be  held  liable  for 
punitive damages and that BP was required to honor its contractual agreements to indemnify us for compensatory damages and release 
its  claims  against  us.    Our  settlements  with  BP  and  the  PSC  finally  resolve  the  indemnity  and  release  issues  (see  “—BP Settlement 
Agreement”  and  “—PSC Settlement  Agreement”)  and,  upon  court  approval  of  such  settlements,  largely  eliminate  our  risk  should  these 
determinations be reversed through the appeal process.  The MDL Court also concluded that we were an “operator” of the Macondo well 
for  purposes  of  33 U.S.C. § 2704(c)(3),  a  provision  of  OPA  that  permits  government  entities  to  recover  removal  costs  by  owners  and 
operators of a facility or vessel that caused a discharge.  The MDL Court, however, found that “Transocean’s liability to government entities 
for removal costs is ultimately shifted to BP by virtue of contractual indemnity,” and BP has agreed to indemnify removal costs through the 
BP Settlement Agreement (see “—BP Settlement Agreement”). 

The Phase One ruling did not quantify damages or result in a final monetary judgment.  However, because it is a determination 
of liability under maritime law, the Phase One ruling is appealable, and we, along with BP, the PSC, Halliburton and the State of Alabama 
have each appealed or cross-appealed aspects of the ruling.  These appeals have been stayed pending the finalization and court approval 
of BP’s settlement with the U.S. and the States.  As a result of our settlements, we do not expect any party to challenge the ruling with 
respect to Transocean when the appeals resume, and we expect that any remaining issues in the appeal would be addressed to the other 
parties. 

We can provide no assurances as to the outcome of these appeals, as to the timing of any further rulings, or that we will not 
enter into additional settlements as to some or all of the matters related to the Macondo well incident, including those to be determined at a 
trial, or the timing or terms of any such settlements. 

Pending  claims—As  of  December 31,  2015,  approximately  1,376 actions  or  claims  are  pending  against  us,  along  with  other 
unaffiliated defendants arising from individual complaints as well as putative class-action complaints that were filed in the federal and state 
courts in Louisiana, Texas, Mississippi, Alabama, Georgia, Kentucky, South Carolina, Tennessee, Florida and other courts.  These claims 
were originally filed in various state and federal courts, and most have been consolidated in the MDL Court.  We believe our settlement 
with  the  PSC,  if  approved  by  the  MDL Court,  will  resolve  many  of  these  pending  actions.    As  for  any  actions  not  resolved  by  these 
settlements, including any claims by individuals who opt-out of the PSC Settlement Agreement, claims by private environmental groups, 
and securities actions, we are vigorously defending those claims and pursuing any and all defenses available. 

State  and  other  government  claims—Claims  have  been  filed  against  us  by  over  200 state,  local  and  foreign  governments, 
including  the  Mexican  States  of  Veracruz,  Quintana  Roo,  Tamaulipas  and  Yucatan;  the  federal  government  of  Mexico  and  other  local 
governments by and on behalf of multiple towns and parishes. 

The  OPA  claims  of  the  Mexican  States  of  Veracruz,  Quintana  Roo,  Tamaulipas  and  Yucatan  were  dismissed  for  failure  to 
demonstrate that recovery under OPA was authorized by treaty or executive agreement.  The MDL Court subsequently granted summary 
judgment  and  the  Fifth Circuit  upheld  the  decision  on  the  Mexican  States’  general  maritime  law  claims  on  the  ground  that  the  federal 
government  of  Mexico,  rather  than  the  Mexican  States,  had  the  proprietary  interest  in  the  claims,  and  the  U.S.  Supreme  Court  denied 
review. 

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 related 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 
and sought compensatory and rescissory damages and attorneys’ fees.  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, which heard oral 
argument on August 18, 2015.  The court has not yet issued a ruling. 

Wreck removal—In December 2010, the U.S. Coast Guard requested that we formulate and submit a comprehensive oil removal 
plan to remove any diesel fuel that could be recovered from the Deepwater Horizon vessel.  The U.S. Coast Guard has not requested that 
we remove the rig wreckage from the sea floor.  However, in February 2013, the U.S. Coast Guard submitted a request seeking analysis of 
the  rig’s  riser  and  cofferdam,  which  are  resting  on  the  seafloor,  and  recommendations  for  remediation  or  removal.    Although  we  have 
insurance coverage for wreck removal, such coverage may be less  than the total costs required to remove the wreckage from the sea 
floor.  Under the BP Settlement Agreement, we have agreed to indemnify BP for any costs associated with wreck removal, if requested. 

Insurance  coverage—At  the  time  of  the  Macondo well  incident,  our  excess  liability  insurance  program  offered  aggregate 
insurance  coverage  of  $950 million,  excluding  a  $15 million  deductible  and  a  $50 million  self-insured  layer  through  our  wholly  owned 
captive  insurance  subsidiary.    This  excess  liability  insurance  coverage  consisted  of  a  first and  a  second layer  of  $150 million  each,  a 
third and fourth layer of $200 million each and a fifth layer of $250 million.  We have recovered costs under the first four excess layers, the 
limits of which are now fully exhausted.  We have submitted claims to the $250 million fifth layer, which if paid, will exhaust such coverage.  
This  layer  is  comprised  of  Bermuda  market  insurers  (the  “Bermuda  Insurers”).    The  Bermuda Insurers  have  asserted  various  coverage 
defenses to our claims, and we have issued arbitration notices to the Bermuda Insurers.

Other legal proceedings 

Asbestos  litigation—In  2004,  several  of  our  subsidiaries  were  named,  along  with  numerous  other  unaffiliated  defendants,  in 
21 complaints  filed  on  behalf  of  769 plaintiffs  in  the  Circuit  Courts  of  the  State  of  Mississippi  and  which  claimed  injuries  arising  out  of 
exposure to asbestos allegedly contained in drilling mud during these plaintiffs’ employment in drilling activities between 1965 and 1986.  
The complaints generally allege that the defendants used or manufactured asbestos containing drilling mud additives for use in connection 
with drilling operations and have included allegations of negligence, products liability, strict liability and claims allowed under the Jones Act 
and  general  maritime  law.    In  each  of  these  cases,  the  complaints  have  named  other  unaffiliated  defendant  companies,  including 
companies  that  allegedly  manufactured  the  drilling-related  products  that  contained  asbestos.    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.  After ten years of litigation, this group of cases has been winnowed to the point where 
now only 15 plaintiffs’ individual claims remain pending in Mississippi in which we have or may have an interest.  During the year ended 
December 31,  2014,  a  group  of  lawsuits  premised  on  the  same  allegations  as  those  in  Mississippi  were  filed  in  Louisiana.    As  of 
December 31, 2015, eight plaintiffs have claims pending against one or more of our subsidiaries in four different lawsuits filed in Louisiana.  
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  was  involved  in  lawsuits  arising  out  of  the  subsidiary’s  involvement  in  the  design,  construction  and 
refurbishment of major industrial complexes.  The operating assets of the subsidiary were sold  and its operations were discontinued in 
1989, and the subsidiary has no remaining assets other than the insurance policies involved in its litigation, with its insurers and, either 
directly  or  indirectly  through  a  qualified  settlement  fund.    The  subsidiary  has  been  named  as  a  defendant,  along  with  numerous  other 
companies,  in  lawsuits  alleging  bodily  injury  or  personal  injury  as  a  result  of  exposure  to  asbestos.    As  of  December 31,  2015,  the 
subsidiary  was  a  defendant  in  approximately  291 lawsuits,  some  of  which  include  multiple  plaintiffs,  and  we  estimate  that  there  are 
approximately 324 plaintiffs in these lawsuits.  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 first of the asbestos-related lawsuits was filed against the subsidiary in 1990.  Through December 31, 2015, the 
costs  incurred  to  resolve  claims,  including  both  defense  fees  and  expenses  and  settlement  costs,  have  not  been  material,  all  known 
deductibles have been satisfied or are inapplicable, and the subsidiary’s defense fees and expenses and settlement costs have been met 
by insurance made available to the subsidiary.  The subsidiary continues to be named as a defendant in additional lawsuits, and we cannot 
predict  the  number  of  additional  cases  in  which  it  may  be  named  a  defendant  nor  can  we  predict  the  potential  costs  to  resolve  such 
additional  cases  or  to  resolve  the  pending  cases.    However,  the  subsidiary  has  in  excess  of  $1.0 billion  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 from settlements and claims 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 believe that the ultimate liability, if any, arising from these claims  will have a 
material impact on our consolidated statement of financial position, results of operations or cash flows. 

Rio de Janeiro tax assessment—In the third quarter of 2006, we received tax assessments of BRL 450 million, equivalent to 
approximately $114 million, including interest and penalties, from  the state tax authorities of Rio de Janeiro in Brazil against one of our 
Brazilian subsidiaries for taxes on equipment imported into the state in connection with our operations.  The assessments resulted from a 
preliminary finding by these authorities that our record keeping practices were deficient.  We currently believe that the substantial majority 
of these assessments are without merit.  We filed an initial response with the Rio de Janeiro tax authorities on September 9, 2006 refuting 
these  additional  tax  assessments.    In  September 2007,  we  received  confirmation  from  the  state  tax  authorities  that  they  believe  the 
additional tax assessments are valid, and as a result, we filed an appeal on September 27, 2007 to the state Taxpayer’s Council contesting 
these assessments.  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. 

Brazilian import license assessment—In the fourth quarter of 2010, we received an assessment from the Brazilian federal tax 
authorities in Rio de Janeiro of BRL 575 million, equivalent to approximately $145 million, including interest and penalties, based upon the 
alleged failure to timely apply for import licenses for certain equipment and for allegedly providing improper information on import license 
applications.  We believe that a substantial majority of the assessment is without merit and are vigorously pursuing legal remedies.  The 
case was decided partially in favor of our Brazilian subsidiary in the lower administrative court level.  The decision cancelled the majority of 
the assessment, reducing the total assessment to BRL 38 million, equivalent to approximately $10 million.  On July 14, 2011, we filed an 
appeal to eliminate the assessment.  On May 23, 2013, a ruling was issued that eliminated all assessment amounts.  A further appeal by 
the taxing authorities was filed in November 2014 and accepted for review in April 2015.  While we cannot predict or provide assurance as 
to  the  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 

AR-91 

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

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. 

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  Environment  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 form of the agreement is a 
consent decree, which has been entered by the court.  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. 

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.  This site was formerly owned and operated by certain of 
our subsidiaries.  It is presently owned by an unrelated party, which received an order to test the property.  We have also been advised 
that one or more of our subsidiaries is likely to be named by the EPA as a PRP for the San Gabriel Valley, Area 3, Superfund site, which 
includes this property.  Testing has been completed at the property, but no contaminants of concern were detected.  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  which  are  likely  to  be  asserted,  is  adequately  accrued  and  should  not  have  a  material  effect  on  our  consolidated  statement  of 
financial position or results of operations. 

Retained risk 

Overview—Our  hull  and  machinery  and  excess  liability  insurance  program  is  comprised  of  commercial  market  and  captive 
insurance  policies  that  we  renew  annually  on  May 1.    We  periodically  evaluate  our  insurance  limits  and  self-insured  retentions.    At 
December 31,  2015,  the  insured  value  of  our  drilling  rig  fleet  was  approximately  $20.4 billion,  excluding  our  rigs  under  construction.  
Additionally, we maintain various other commercial lines of insurance covering the business.  We generally do not carry commercial market 
insurance coverage for loss of revenues or for losses resulting from physical damage to our fleet caused by named windstorms in the U.S. 
Gulf of Mexico, including liability for wreck removal costs. 

AR-92 

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

Hull  and  machinery  coverage—At  December 31,  2015,  under  the  hull  and  machinery  program,  we  generally  maintained  a 
$125 million per occurrence deductible, limited to a maximum of $200 million per policy period.  Subject to the same shared deductible, we 
also had coverage for an amount equal to 50 percent of a rig’s insured value for combined costs incurred to mitigate rig damage, wreck or 
debris removal and collision liability.  Any excess wreck or debris removal costs and excess collision liability costs are generally covered to 
the extent of our remaining excess liability coverage. 

Excess  liability  coverage—At  December 31,  2015,  we  carried  excess  liability  coverage  of  $700 million  in  the  commercial 
market excluding the deductibles and self-insured retention noted below, which generally covers offshore risks  such as personal injury, 
third-party  property  claims,  and  third-party  non-crew  claims,  including  wreck  removal  and  pollution.    Our  excess  liability  coverage  had 
separate  $10 million  per  occurrence  deductibles  on  collision  liability  claims  and  $5 million  per  occurrence  deductibles  on  crew  personal 
injury claims and on other third-party non-crew claims.  Through our wholly owned captive insurance company, we retained the risk of the 
primary $50 million excess liability coverage.  In addition, we generally retained the risk for any liability losses in excess of $750 million. 

Letters of credit and surety bonds 

At December 31, 2015 and 2014, we had outstanding letters of credit totaling $153 million and $338 million, respectively, issued 
under  various  committed  and  uncommitted  credit  lines  provided  by  several  banks  to  guarantee  various  contract  bidding,  performance 
activities and customs obligations.  At December 31, 2014, such outstanding letters of credit included an amount of $91 million that we 
agreed  to  maintain  in  support  of  the  operations  for  Shelf Drilling.    Our  commitment  to  provide  such  financial  support  expired  in 
November 2015 (see Note 7—Discontinued Operations). 

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, 2015 and 2014, we had outstanding 
surety bonds totaling $30 million and $6 million, respectively.

Angola  Deepwater  Drilling  Company Limited—We  own  a  65 percent  interest  and  Angco  Cayman Limited  (“Angco  Cayman”) 
owns a 35 percent interest, in ADDCL, a variable interest entity (see Note 4—Variable Interest Entities).  Angco Cayman has the right to 
require  us  to  purchase  its  shares  for  cash.    Accordingly,  we  present  the  carrying  amount  of  Angco  Cayman’s  ownership  interest  as 
redeemable noncontrolling interest on our consolidated balance sheets. 

Noncontrolling  interest—On  February 6,  2014,  we  formed  Transocean Partners  to  own,  operate  and  acquire  modern, 
technologically  advanced  offshore  drilling  rigs.    Transocean Partners  holds  a  51 percent  ownership  interest  in  the  entities  that  own  and 
operate the ultra-deepwater floaters Development Driller III, Discoverer Clear Leader and Discoverer Inspiration, all of which are currently 
located  in  the  U.S.  Gulf  of  Mexico.    On  August 5,  2014,  we  completed  the  initial  public  offering  of  20.1 million  common  units  of 
Transocean Partners.  We hold the remaining 21.3 million common units, 27.6 million subordinated units, which collectively represented a 
70.8 percent limited liability company interest, and all of the incentive distribution rights.  In the year ended December 31, 2014, as a result 
of the offering, we received cash proceeds of $417 million, net of $26 million for underwriting discounts and commissions and other offering 
costs, and we recorded a capital allocation resulting in a decrease of $44 million to noncontrolling interest and a corresponding increase to 
additional paid-in capital. 

On  November 4,  2015,  Transocean Partners  announced  that  its  board  of  directors  approved  a  unit  repurchase  program, 
authorizing it to repurchase up to $40 million of its publicly held common units.  Subject to market conditions, Transocean Partners may 
repurchase units from time to time in the open market or in privately negotiated transactions.  It may suspend or discontinue the program at 
any  time.    The  common  units  repurchased  under  the  program  will  be  cancelled.    In  the  year  ended  December 31,  2015, 
Transocean Partners  repurchased 91,500  of  its  publicly  held  common  units  for  an  aggregate  purchase  price  of  $1 million.    As  of 
December 31, 2015, we held a 70.9 percent limited liability company interest in Transocean Partners. 

In  the  years  ended  December 31,  2015  and  2014,  Transocean Partners  declared  and  paid  an  aggregate  distribution  of 
$100 million and $15 million, respectively, to its unitholders, of which $29 million and $4 million, respectively, was paid to  the holders of 
noncontrolling interest and $71 million and $11 million, respectively, was paid to us and was eliminated in consolidation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

During the years ended December 31, 2015 and 2014, as a result of transactions with holders of noncontrolling interest in other 
subsidiaries, we recorded an allocation of capital, which resulted in a decrease of $9 million and an increase of $11 million, respectively, to 
noncontrolling interest with corresponding adjustments to additional paid-in capital. 

See Note 5—Impairments. 

Note 16—Shareholders’ Equity 

Par value reduction—On October 29, 2015, shareholders at our extraordinary general meeting 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.  See Note 25—Subsequent Events. 

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.  We do not pay the distribution of 
qualifying additional paid-in capital with respect to our shares held in treasury or held by our subsidiary.  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,  shareholders  at  the  extraordinary  general  meeting  approved  the 
cancellation  of  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.  We do not pay the distribution of qualifying additional paid-in capital with respect to our 
shares held in treasury or held by our subsidiary.  In May 2014, we recognized a liability of $1.1 billion for the distribution payable, recorded 
in other current liabilities, with a corresponding entry to additional paid-in capital.  On June 18, September 17 and December 17, 2014, we 
paid  the  first three installments  in  the  aggregate  amount  of  $816 million  to  shareholders  of  record  as  of  May 30,  August 22  and 
November 14, 2014, respectively.  At December 31, 2014, the aggregate carrying amount of the distribution payable was $272 million.  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. 

In May 2013, 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  $2.24 per  outstanding  share,  payable  in  four quarterly  installments  of  $0.56  per 
outstanding share, subject to certain limitations.  We do not pay the distribution of qualifying additional paid-in capital with respect to our 
shares  held  in  treasury  or  held  by  our  subsidiary.    In  May 2013,  we  recognized  a  liability  of  $808 million  for  the  distribution  payable, 
recorded in other current liabilities, with a corresponding entry to additional paid-in capital.  On June 19, September 18 and December 18, 
2013, we paid the first three installments in the aggregate amount of $606 million to shareholders of record as of May 31, August 23 and 
November 15,  2013,  respectively.    On  March 19,  2014,  we  paid  the  final  installment  in  the  aggregate  amount  of  $202 million  to 
shareholders of record as of February 21, 2014. 

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,  equivalent  to  approximately  $3.5 billion.    On  February 12,  2010,  our  board  of  directors  authorized  our  management  to 
implement the share repurchase program. 

During the years ended December 31, 2015, 2014 and 2013, we did not purchase any of our shares under our share repurchase 
program.  At December 31, 2015 and 2014, we held 2.9 million shares in treasury, recorded at cost.  On October 29, 2015, shareholders at

Note 17—Share-Based Compensation Plans 

Overview 

We  have  (i) 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 and (ii) other incentive plans under which awards are currently outstanding.  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, 2015, we had 55.4 million shares authorized and 21.2 million shares available to be granted under the Long-Term Incentive 
Plan. 

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  are  typically  awarded  subject  to  a  three-year 
measurement  period  during  which  the  number  of  options,  shares  or  restricted  share  units  remains  uncertain.    At  the  end  of  the 
measurement period, the awarded number of options, shares or restricted share units is determined subject to the stated vesting period.  
The  performance  awards  generally  vest  in  one aggregate  installment  following  the  determination  date.    Stock  options  and  stock 
appreciation rights, once vested, generally have a seven-year term during which they are exercisable. 

As of December 31, 2015, total unrecognized compensation costs related to all unvested share-based awards were $61 million, 
which  are  expected  to  be recognized  over  a  weighted-average period  of  1.7 years.    In  the  years  ended  December 31,  2015,  2014  and 
2013, we recognized additional share-based compensation expense of $9 million, $9 million and $22 million, respectively, in connection 
with modifications of share-based awards. 

Service awards 

Restricted share units—A restricted share unit, also known as a deferred unit, is a notional unit that is equal to one share but 
has no voting rights until the underlying share is issued.  Our service-based restricted share units are participating securities since they 
have  the  right  to  receive  dividends  and  other  cash  distributions  to  shareholders.    The  following  table  summarizes  unvested  activity  for 
service-based restricted share units granted under our incentive plans during the year ended December 31, 2015:

During the year ended December 31, 2015, the aggregate grant-date fair value of the service-based restricted share units that 

vested was $81 million. 

During  the  years  ended  December 31,  2014  and  2013,  we  granted  1,208,790  and  1,691,029 service-based  restricted  share 
units, respectively, with a weighted-average grant-date fair value of $42.80 and $58.91 per share, respectively.  During the years ended 
December 31,  2014  and  2013,  we  had  1,520,023  and  1,556,840 service-based  restricted  share  units,  respectively,  that  vested  with  an 
aggregate grant-date fair value of $87 million and $95 million, respectively. 

Stock options—In the years ended December 31, 2015 and 2014, we did not grant service awards in the form of stock options.  
In the year ended December 31, 2013, we estimated the grant date fair value of each stock option awarded under the Long-Term Incentive 
Plan  to  be  $17.37 per  option.    We  estimated  the  fair  value  using  the  Black-Scholes-Merton  option-pricing  model  with  the  following 
weighted-average assumptions: (a) a dividend yield of 2 percent, (b) an expected price volatility of 39 percent, (c) a risk-free interest rate of 
0.94 percent and (d) an expected option life of 5.3 years.

During the year ended December 31, 2015, no outstanding service-based stock options were exercised.  During the year ended 
December 31, 2015, the aggregate grant-date fair value of service-based stock options that vested was $9 million.  As of December 31, 
2015, there were outstanding unvested service-based stock options to purchase 54,506 shares At January 1 and December 31, 2015, we 
have presented the aggregate intrinsic value as zero since the weighted-average exercise price per share exceeded the market price of 
our shares on these dates. 

During  the  year  ended  December 31,  2013,  we  granted  service-based  stock  options  to  purchase  455,915 shares  with  a 
weighted-average grant-date fair value of $17.37 per service-based stock option.  During the years ended December 31, 2014 and 2013, 
the total grant-date fair value of service-based stock options that vested was $14 million and $12 million, respectively.  During the years 
ended  December 31,  2014  and  2013,  there  were  service-based  stock  options  to  purchase  383,848  and  102,254 shares  exercised,

Performance awards 

Restricted share units—We grant performance awards in the form of restricted share units that can be earned depending on 
the  achievement  of  (a) market  factors  or  (b) both  market  factors  and  performance  targets.    Our  performance  awards  are  participating 
securities since they have the right to receive dividends and other cash distributions to shareholders.  The number of restricted share units 
earned is quantified upon completion of the specified period at the determination date.  The following table summarizes unvested activity

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, which approximates fair value because of the short maturities of those instruments.  We measured the estimated fair value of our 
cash  equivalents  using  significant  other  observable  inputs,  representative  of  a  Level 2  fair  value  measurement,  including  the  net  asset 
values of the investments.  At December 31, 2015 and 2014, the aggregate carrying amount of our cash equivalents was $1.7 billion. 

Loans receivable—We previously held certain loans receivable, which originated in connection with certain asset dispositions.  
The  carrying  amount  represents  the  amortized  cost  of  our  investments.    We  measured  the  estimated  fair  value  using  significant 
unobservable inputs, representative of a Level 3 fair value measurement, including the credit ratings of the borrowers.  At December 31, 
2014, the aggregate carrying amount of our loans receivable was $15 million, recorded in other assets. 

Restricted  cash  investments—The  carrying  amount  of  the  Eksportfinans  Restricted  Cash  Investments  represents  the 
amortized  cost  of  our  investment.    We  measured  the  estimated  fair  value  of  the  Eksportfinans  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,  2015  and  2014,  the  aggregate  carrying  amount  of  the  Eksportfinans  Restricted  Cash  Investments  was 
$216 million and $369 million, respectively.  At December 31, 2015 and 2014, the estimated fair value of the Eksportfinans Restricted Cash 
Investments was $223 million and $386 million, respectively. 

The carrying amount of the restricted cash balances that are subject to restrictions due to 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, 
2015 and 2014, the aggregate carrying amount of such restricted cash balances was $251 million and $8 million, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

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. 

Derivative  instruments—The  carrying  amount  of  our  derivative  instruments  represents  the  estimated  fair  value,  excluding 
accrued interest.  We measured the estimated fair value using significant other observable inputs, representative of a Level 2 fair value 
measurement, including the interest rates and terms of the instruments. 

Note 21—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  changes  with  market 
interest  rates.    Floating  rate  debt,  where  the  interest  rate  may  be  adjusted  annually  or  more  frequently  over  the  life  of  the  instrument, 
exposes us to short-term changes in market interest rates.  Fixed rate debt, where the interest rate is fixed over the life of the instrument 
and the instrument’s maturity is greater than one year, exposes us to changes in market interest rates when we refinance maturing debt 
with new debt.  Our fixed-rate restricted cash investments associated with the Eksportfinans Loans and the respective debt instruments for 
which they are restricted, are subject to corresponding and opposing changes in the fair value relative to changes in market interest rates. 

From time to time, we may use interest rate swap agreements to manage the effect of interest rate changes on future income.  
We do not generally enter into interest rate derivative transactions for speculative or trading purposes.  Interest rate swaps are generally 
designated  as  hedges  of  underlying  future  interest  payments.    These  agreements  involve  the  exchange  of  amounts  based  on  variable 
interest rates and amounts based on a fixed interest rate over the life of the agreement without an exchange of the notional amount upon 
which the payments are based.  The interest rate differential to be received or paid on the swaps is recognized over the lives of the swaps 
as an adjustment to interest expense.  Gains and losses on terminations of interest rate swap agreements are deferred and recognized as 
an adjustment to interest expense over the remaining life of the underlying debt.  In the event of the early retirement of a designated debt 
obligation, any realized or unrealized gain or loss from the swap would be recognized in income. 

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 and, from time to time, the use of currency exchange derivative instruments. 

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.  In 
situations  where  payments  of  local  currency  do  not  equal  local  currency  requirements,  we  may  use  currency  exchange  derivative 
instruments,  specifically  forward  exchange  contracts,  or  spot  purchases,  to  mitigate  currency  exchange  rate  risk.    A  forward  exchange 
contract  obligates  us  to  exchange  predetermined  amounts  of  specified  foreign  currencies  at  specified  currency  exchange  rates  on 
specified dates or to make an equivalent U.S. dollar payment equal to the value of such exchange. 

Credit  risk—Financial  instruments  that  potentially  subject  us  to  concentrations  of  credit  risk  are  primarily  cash  and  cash 

equivalents, short-term investments, trade receivables, notes and loans receivable and equity investment. 

We generally maintain our cash and cash equivalents in time deposits at commercial banks with high credit ratings or mutual 
funds, which invest exclusively in high-quality money market instruments.  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 22—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 isolated credit concerns related to independent oil companies, we are not aware of any significant credit risks related to 
our customer base and do not generally require collateral or other security to support customer receivables. 

We  hold  investments  in  debt  and  equity  instruments  of  certain  privately  held  companies  as  a  result  of  certain  dispositions  of 
assets and equity interests or as a result of arrangements with certain suppliers.  We monitor the financial condition of the investees on an 
ongoing basis to determine whether a valuation allowance is required.

Labor  agreements—We  require  highly  skilled  personnel  to  operate  our  drilling  units.    We  conduct  extensive  personnel 
recruiting,  training  and  safety  programs.    At  December 31,  2015,  we  had  approximately  9,100 employees,  including  approximately 
500 persons engaged through contract labor providers.  Approximately 30 percent of our total workforce, working primarily in Angola, the 
U.K.,  Nigeria,  Norway,  Australia  and  Brazil  are  represented  by,  and  some  of  our  contracted  labor  work  under,  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 apply to all offshore employees 
not just the union members. 

Note 22—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. 

Geographic analysis—Operating revenues for our continuing operations by country were as follows (in millions):

A  substantial  portion  of  our  assets  are  mobile.    Asset  locations  at  the  end  of  the  period  are  not  necessarily  indicative  of  the 
geographic  distribution  of  the  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, 2015 and 2014, the 
aggregate carrying amount of our long-lived assets located in Switzerland was $2 million and $3 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. 

Major  customers—For  the  year  ended  December 31,  2015,  Chevron Corporation  (together  with  its  affiliates,  “Chevron”)  and 
Royal Dutch Shell plc, together with its affiliates, accounted for approximately 14 percent and 10 percent, respectively, of our consolidated 
operating revenues from continuing operations.  For the year ended December 31, 2014, Chevron and BP accounted for approximately 
11 percent  and  nine percent,  respectively,  of  our  consolidated  operating  revenues  from  continuing  operations.    For  the  year  ended 
December 31, 2013, Chevron and BP accounted for approximately 12 percent and 10 percent, respectively, of our consolidated operating 
revenues from continuing operations.

Note 23—Condensed Consolidating Financial Information 

Transocean Inc., a wholly owned subsidiary of Transocean Ltd., is the issuer of certain notes and debentures, which have been 
guaranteed  by  Transocean Ltd.    Transocean Ltd.’s  guarantee  of  debt  securities  of  Transocean Inc.  is  full  and  unconditional.  
Transocean Ltd. is not subject to any significant restrictions on its ability to obtain funds by dividends, loans or return of capital distributions 
from its consolidated subsidiaries. 

The  following  tables  present  condensed  consolidating  financial  information  for  (a) Transocean Ltd.  (the  “Parent  Guarantor”), 
(b) Transocean Inc.  (the  “Subsidiary  Issuer”),  and  (c) the  other  direct  and  indirect  wholly  owned  and  partially  owned  subsidiaries  of  the 
Parent  Guarantor  (the  “Other  Subsidiaries”),  none  of  which  guarantee  any  indebtedness  of  the  Subsidiary  Issuer.    The  condensed 
consolidating financial information may not be indicative of the results of operations, financial position or cash flows had the subsidiaries 
operated as independent entities. 

We have corrected the presentation of our condensed consolidating statements of comprehensive income (loss) for the years 
ended December 31, 2014 and 2013, and our condensed consolidating balance sheets as of December 31, 2014 to properly reflect the 
equity  in  losses  of  certain  Other  Subsidiaries  resulting  from  our  loss  on  impairment  of  goodwill  that  was  previously  presented  in  the 
statement of operations of the Subsidiary Issuer.  We have also corrected the presentation of other amounts related to the capitalization of 
interest expense previously disclosed in the statement of operations of the Other Subsidiaries.  In the year ended December 31, 2014, the 
effect of these corrections reduced net loss and total comprehensive loss for the Subsidiary Issuer by $286 million, increased net loss and 
total comprehensive loss for the Other Subsidiaries by $133 million and decreased the consolidating adjustments by $153 million.  In the 
year  ended  December 31,  2013,  the  effect  of  these  corrections  reduced  net  income  and  total  comprehensive  income  for  the  Other 
Subsidiaries  by  $63 million  and,  correspondingly,  increased  the  consolidating  adjustments.    The  corrections  also  had  a  corresponding 
effect on the investments in affiliates of the Subsidiary Issuer and the total equity of the Other Subsidiaries.  Additionally, on the balance 
sheet as of December 31, 2014, we reclassified certain elimination entries from the consolidating adjustments column, eliminating activity 
among the other subsidiary companies.  Such reclassification reduced the consolidating adjustments by $13.0 billion with a corresponding 
reduction  to  the  respective  balances  of  the  Other  Subsidiaries.    These  changes  had  no  effect  on  the  consolidated  statements  of 
operations, the consolidated balance sheets or the consolidated or consolidating statements of cash flows, as previously reported. 

The  following  tables  include  the  consolidating  adjustments  necessary  to  present  the  condensed  financial  statements  on  a 

consolidated basis (in millions): 

Operating revenues 
Cost and expenses 
Loss on impairment 
Loss on disposal of assets, net

(a)  First quarter, second quarter, third quarter and fourth quarter included an aggregate loss of $692 million associated with the  impairment of certain 
drilling  units  classified  as  assets  held  for  sale.    First quarter  and  second quarter  included  a  loss  of  $507 million  and  $668 million,  respectively, 
associated  with  the  impairment  of  our  deepwater  asset  group  and  midwater  asset  group,  respectively.    Second quarter  included  income  of 
$788 million  associated  with  recoveries  of  previously  incurred  costs  associated  with  the  Macondo well  incident.    Third quarter  and  fourth quarter 
included  an  aggregate  net  gain  of  $23 million  associated  with  the  retirement  of  debt.    See  Note 5—Impairments,  Note 9—Drilling  Fleet  and 
Note 14—Commitments and Contingencies. 

(b)  First quarter and third quarter included a loss of $3 million associated with loss contingencies and income of $22 million associated with insurance 
recoveries,  net,  respectively,  related  to  the  Macondo well  incident.    First,  third  and  fourth quarters  included  an  aggregate  loss  of  $268 million

Contingencies.  

Note 25—Subsequent Events 

Norway  tax  investigations  and  trial—Subsequent  to  December 31,  2015,  the  Norwegian  authorities  formally  and 
unconditionally dropped all criminal charges against our subsidiaries and the two employees of our former external advisors and our former 
external  Norwegian  attorney  regarding  disclosures  in  our  Norwegian  tax  returns  related  to  a  dividend  payment  in  2001  and  regarding 
disclosures  in  our  Norwegian  tax  returns  related  to  an  intercompany  rig  sale  in  1999  and  certain  inaccuracies  in  Norwegian  statutory 
financial statements for the years ended December 31, 1996 through 2001.  As a result, no criminal charges remain outstanding for any of 
the previously reported Norway tax investigations or trials, and all of our subsidiaries and external advisors have been fully acquitted of all 
criminal charges. 

Par value reduction and shares held in treasury—Following a formal notification to creditors and establishment of a public 
deed  of  compliance,  the  reduction  of  our  par  value  and  the  cancellation  of  our  shares  held  in  treasury,  which  were  approved  at  our 
extraordinary  general  meeting  held  on  October 29,  2015,  became  effective  as  of  January 7,  2016  upon  registration  in  the  commercial 
register. 

Postemployment  benefit  plans—Subsequent  to  December 31,  2015,  we  and  the  plan  trustees  mutually  agreed  to  cease 

accruing benefits under the U.K. Plan, effective March 31, 2016. 

Derivatives and hedging—Subsequent to December 31, 2015, we terminated our interest rate swaps previously designated as 
a  fair  value  hedge  of  the  6.0% Senior Notes,  and  we  received  an  aggregate  net  cash  payment  of  $11 million  in  connection  with  the 
settlement.

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—We  carried  out  an  evaluation,  under  the  supervision  and  with  the  participation  of 
management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  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, as defined in the Exchange Act, Rules 13a-15 and 15d-15, were effective 
as of December 31, 2015 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 U.S. Securities and Exchange Commission’s rules and forms. 

Internal  control  over  financial  reporting—There  were  no  changes  to  our  internal  control  over  financial  reporting  during  the 
quarter  ended  December 31,  2015  that  have  materially  affected,  or  are  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 24, 2016 

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-2 to SR-12), for the year ended December 31, 2015. 

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,  2015  comply  with  Swiss  law  and  the  company’s  articles  of 
incorporation. 

Report on other legal requirements 
We  confirm  that  we  meet  the  legal  requirements  on  licensing  according  to  the  Auditor  Oversight  Act  (AOA)  and  independence 
(article 728 CO and article 11 AOA) and that there are no circumstances incompatible with our independence. 

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

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

Furthermore, we draw attention to the fact that half of the share capital and legal reserves are no longer covered (article 725 para. 1 CO).  
Note 5 and note 10 of the financial statements describe the qualified capital loss and the subsequent events related thereto.

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 Services AS, our wholly-owned subsidiaries.  Transocean Ltd. is registered with the commercial register in the canton of 
Zug, and its stock is listed on the New York Stock Exchange (“NYSE”) and on the SIX Swiss Exchange (“SIX”).  We have seven full time 
employees. 

On November 23, 2015, we announced our intent to delist our shares from the SIX, and on December 17, 2015, we announced 
that the SIX listing authorities approved our application to delist our shares.  Such delisting is expected to become effective on March 31, 
2016, with the last trading day scheduled to be March 30, 2016.  Our shares will continue to be listed and traded on the NYSE. 

On October 29, 2015, shareholders at our extraordinary general meeting approved the following: a) the reduction of the par value 
of each of our shares to CHF 0.10 from the original par value of CHF 15.00, b) the cancellation of all 2.9 million shares repurchased under 
our share repurchase program and c) the cancellation of the third and fourth installments of the distribution of statutory capital reserves 
from capital contribution in the form of a United States (“U.S.”) dollar denominated dividend of a total of USD 0.60 per outstanding share. 
See Note 10—Subsequent Events. 

Note 2—Significant Accounting Policies 

Presentation—Beginning  in  the  year  ended  December 31,  2015,  we  have  prepared  our  unconsolidated  statutory  financial 
statements  in  accordance  with  the  general  accepted  accounting  principles  as  set  out  in  Art. 957  to  Art. 963b,  of  the  Swiss  Code  of 
Obligations  (the  “CO”),  which  became  effective  since  January 1,  2013,  and  required  implementation  in  relation  to  the  year  ended 
December 31,  2015.    Consequently,  we  have  adjusted  the  presentation  of  the  prior  year  financial  statements  to  conform  to  the  current 
presentation.    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. 

Foreign  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 foreign 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 foreign 
currencies using the average currency exchange rates for the year. 

Our principal exchange rates were as follows: 

CHF / USD 
CHF / GBP 
CHF / NOK

We  recognize  realized  currency  exchange  and  translation  gains  and  losses  arising  from  business  transactions  and  net 
unrealized  currency  exchange  and  translation  losses  in  current  period  earnings.    We  defer  net  unrealized  currency  exchange  and 
translation gains and record such deferred gains in other current liabilities. 

Cash—We hold cash balances, denominated in Swiss francs and U.S. dollars, which include cash deposited in demand bank 

accounts, money market investment accounts and other liquid investments and interest earned on such cash balances. 

Current assets and liabilities—We record current assets at historical cost less adjustments for impairment of value and current 

liabilities at historical cost. 

Investments in subsidiaries—We record our investments in subsidiaries at acquisition cost less adjustments for impairment of 
value.  We evaluate our investments in subsidiaries for impairment annually and record an impairment loss when the carrying amount of 
such assets exceeds the fair value.  We estimate fair value of our investments using a variety of valuation methods, including the income 
and market approaches.  Our estimates of fair value represent a price that would be received to sell the asset in an orderly transaction 
between market participants in the principal market for the asset. 

Own shares—We recognize own shares at acquisition cost, which we present as a deduction from shareholders’ equity at the 

time of acquisition.  For own shares held by subsidiaries, we build a reserve for shares in equity at the respective acquisition costs. 

Related parties—In the meaning of the CO, we consider related parties to be only shareholders, direct and indirect subsidiaries, 

and the board of directors.

NOTES TO STATUTORY FINANCIAL STATEMENTS—continued 

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 3.5 billion using a currency exchange rate of USD 1.00 to CHF 0.99 as of the close of 
trading on December 31, 2015.  In the years ended December 31, 2015 and 2014, we did not repurchase any shares under the share 
repurchase  program.    At  December 31,  2015  and  2014,  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, shareholders at our extraordinary general meeting 
approved the cancellation of all the 2.9 million shares that have been repurchased under our share repurchase program.  See Note 10—
Subsequent Events. 

Shares  held by  subsidiary—Transocean Inc.  holds  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,  2015  and  2014,  we 
transferred  1.8 million  and  1.5 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 year ended December 31, 2015 and 2014, we received cash proceeds of 
less than CHF 1 million and CHF 1 million respectively, in connection with own shares transferred in exchange for equity awards exercised 
or withheld for taxes under our share-based compensation plans.

NOTES TO STATUTORY FINANCIAL STATEMENTS—continued 

Conditional  share  capital—Our  articles  of  association  provide  for  a  conditional  share  capital  that  permits  us  to  issue  up  to 
167.6 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.  

Par  value  reduction  and  cancellation  of  shares—On  October 29,  2015,  shareholders  at  our  extraordinary  general  meeting 
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 the cancellation of 
all 2.9 million shares repurchased under our share repurchase program.  See Note 10—Subsequent Events. 

Distributions  to  shareholders—In  May 2015,  at  our  annual  general  meeting,  our  shareholders  approved  a  distribution  of 
statutory capital reserves from capital contribution in the form of a U.S. dollar denominated dividend of USD 0.60 per outstanding share, 
payable in four installments of USD 0.15 per outstanding share, subject to certain limitations.  In May 2015, we transferred CHF 422 million 
from  statutory  capital  reserves—reserve  from  capital  contribution  to  free  reserves—dividend  reserve  from  capital  contribution,  and  we 
recognized  a  distribution  payable  of  CHF 210 million,  with  the  corresponding  entry  to  free  reserves—dividend  reserve  from  capital 
contribution.  On June 17, 2015 and September 23, 2015, we paid the first two installments, in the aggregate amount of CHF 104 million, 
to shareholders of record as of May 29, 2015 and August 25, 2015, respectively. 

On  October 29,  2015,  shareholders  at  the  extraordinary  general  meeting  approved  the  cancellation  of  the  third and 
fourth installments of the distribution approved at our annual general meeting held on May 15, 2015.  Upon approval of the cancellation, we 
transferred the remaining CHF 318 million from free reserves—dividend reserve from capital contribution to statutory capital reserve from 
capital contribution, in accordance with the tax ruling dated April 2, 2013. 

In May 2014, at our annual general meeting, our shareholders approved a distribution of statutory capital reserves from capital 
contribution  in  the  form  of  a  U.S.  dollar  denominated  dividend  of  USD 3.00 per  outstanding  share,  payable  in  four installments  of 
USD 0.75 per  outstanding  share,  subject  to  certain  limitations.    In  May 2014,  we  transferred  CHF 2.0 billion  from  statutory  capital 
reserves—reserve from capital contribution to free reserves—dividend reserve from capital contribution, and we recognized a distribution 
payable of CHF 1.0 billion, with the corresponding entry to free reserves—dividend reserve from capital contribution.  On June 18, 2014, 
September 17,  2014  and  December 17,  2014,  we  paid  the  first three installments,  in  the  aggregate  amount  of  CHF 765 million,  to 
shareholders of record as of May 30, 2014, August 22, 2014 and November 12, 2014, respectively.  At December 31, 2014, the carrying 
amount of the unpaid distribution payable was CHF 264 million.  On March 18, 2015, we paid the final installment, in the aggregate amount 
of CHF 275 million, to shareholders of record as of February 20, 2015.  Upon payment of the final installment, we transferred the remaining 
CHF 1.0 billion from free reserves—dividend reserve from capital contribution to statutory reserve from capital contribution, in accordance 
with the tax ruling dated April 2, 2013. 

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 must, in these circumstances, convene a general meeting of 
shareholders and propose measures that remedy such a capital loss.  On October 29, 2015, shareholders at our extraordinary general 
meeting 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.  At December 31, 2015, our qualified 
capital loss remained unremediated pending establishment of a public deed of compliance for our par value reduction and registration in 
the commercial register.  See Note 10—Subsequent Events.

capital.  See Note 4—Own Shares. 

Further, we agreed with Carl Icahn and certain investment funds managed by Mr. Icahn (collectively, the “Icahn Group”) to make 
certain  proposals  for  approval  by  the  shareholders  at  the  2014 annual  general  meeting.    These  proposals  related  to  the  2014 dividend 
distribution, Icahn Group designated board nominees, and an amendment to our articles of association regarding the maximum size of our 
board of directors.  The Icahn Group committed to certain standstill restrictions and to vote in favor of our slate of director nominees and 
certain  other  proposals  our  board  of  directors  recommended  at  the  2014 annual  general  meeting.    At  December 31,  2015  and 
December 31, 2014, the Company and the Icahn Group, together, held 31.3 million registered shares and 33.0 million registered shares, 
respectively, representing 8.36 percent and 8.83 percent, respectively, of the issued share capital.  Note that the most recent information 
on  the  individual  beneficial  shareholding  of  Icahn  Group  dated  as  of  November 10,  2013,  corresponding  to  approximately  21.5 million 
registered shares.  The decrease in the reported number of registered shares held by us and the Icahn Group together is attributable to the 
decrease in own shares held by us as at December 31, 2015 compared to the own shares held by us as at December 31, 2014.

Transocean Inc. debt obligations—Transocean Inc. has issued certain debt securities or entered into other debt instruments, 
including  notes,  revolving  credit  facilities,  debentures,  surety  bonds,  letters  of  credit,  and  convertible  note  obligations.    We  have 
guaranteed certain of these debt securities or other debt instruments.  We are not subject to any significant restrictions on their ability to 
obtain funds from their consolidated subsidiaries by dividends, loans or return of capital distributions.  At December 31, 2015 and 2014, the 
aggregate  carrying  amount  of  debt  that  we  have  guaranteed  was  USD 7.4 billion  and  USD 8.8 billion,  equivalent  to  approximately 
CHF 7.3 billion and CHF 8.7 billion, respectively. 

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 have 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 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, 
2015 and 2014, we recognized guarantee fee income of CHF 3 million and CHF 7 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 resolves all matters relating to suspension, debarment and statutory disqualification arising 
from the matters contemplated by the Plea Agreement.  Subject to compliance with the terms of the EPA Agreement, the EPA agreed that 
it  will  not  suspend,  debar  or  statutorily  disqualify  the  Respondents  and  will  lift  any  existing  suspension,  debarment  or  statutory 
disqualification.  We have guaranteed the obligations required of the Respondents under the EPA Agreement. 

Norway tax investigations and trial contingent obligations—At December 31, 2015, certain of our wholly-owned subsidiaries 
were involved in ongoing investigations by Norwegian civil tax and criminal authorities relating to various transactions undertaken in 2001 
and 2002 as well as the actions of certain employees of our former external tax advisors on these transactions.  The authorities issued tax 
assessments related to certain restructuring transactions, migration of a subsidiary that was previously subject to tax in Norway, a 2001 
dividend  payment,  certain  currency  exchange  deductions  and  dividend  withholding  tax.    In  prior  years,  we  guaranteed  these  tax 
assessments and related contingent obligations.  At December 31, 2013, the aggregate amount of our guarantee with respect to these tax 
disputes was NOK 699 million, equivalent to approximately CHF 102 million.  In September 2014, the Norwegian tax authorities formally 
abandoned  part  of  the  claim  by  issuing  a  revised  writ,  and  we  reduced  our  guarantee  to  NOK 35 million,  equivalent  to  approximately 
CHF 5 million.    In  October 2014,  the  Norwegian  tax  authorities  formally  dismissed  all  remaining  claims  related  to  the  migration  of  our 
subsidiary  that  was  previously  subject  to  tax  in  Norway.    As  a  result,  we  terminated  the  guarantee  of  NOK 35 million,  equivalent  to

approximately  CHF 5 million.    At  December 31,  2015,  the  outstanding  civil  tax  assessments  were  as  follows:    (a) NOK 412 million, 
equivalent  to  approximately  CHF  45 million,  plus  interest,  related  to  a  2001  dividend  payment  and  (b) NOK 43 million,  equivalent  to 
approximately  CHF  5 million,  plus  interest,  related  to  certain  foreign  exchange  deductions  and  dividend  withholding  tax.    See  Note 10– 
Subsequent Events 

Transocean Management Ltd. office lease obligation—Transocean Management Ltd., has entered into a lease obligation for 
its  principal  offices  in  Vernier,  Switzerland.    Under  an  uncommitted  line  of  credit,  Transocean Ltd.  has  issued  a  surety  bond  in  the  full 
amount  of  this  lease  obligation.    At  December 31,  2015  and  2014,  our  guarantee  for  the  Transocean  Management Ltd.  office  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  Transocean Ltd.’s  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.  Although we can provide no assurance as to the outcome of the remaining claims, 
we believe that a significant portion of the contingencies related to the Macondo well incident are now resolved. 

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, which heard oral argument on August 18, 2015.  The court has not yet issued a ruling. 

Macondo well incident insurance coverage—On February 13, 2015, the Texas Supreme Court issued its answer to one of the 
Fifth Circuit’s questions by determining that BP is not entitled to coverage under certain of our insurance policies for damages arising from 
subsurface pollution because BP assumed, and we did not assume, liability for such claims.  On May 20, 2015, the Macondo Subsidiaries 
entered  into  a  settlement  agreement  with  BP  in  which  BP  agreed,  among  other  things,  to  cease  its  efforts  to  recover  as  an  unlimited 
additional  insured  under  our  insurance  policies  and  to  be  bound  by  the  insurance  reimbursement  rulings  related  to  the  Macondo  well 
incident. 

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.—Transocean Inc. holds our shares to satisfy, on our behalf, our obligation to deliver shares in connection with 
awards granted under our incentive plans, warrants or other right to acquire our shares.  At December 31, 2015 and 2014, Transocean Inc. 
held 6.9 million and 8.7 million of our shares, respectively, for this purpose. 

We  and  Transocean Inc.,  as  the  borrower  and  lender,  respectively,  entered  into  a  credit  agreement  dated  June 1,  2011, 
establishing  a  USD 2.0 billion  revolving  credit  facility.    In  the  year  ended  December 31,  2014,  Transocean Inc.  declared  a  dividend  for 
USD 1.5 billion,  equivalent  to  approximately  CHF 1.4 billion,  in  satisfaction  of  amounts  due  under  the  revolving  credit  facility.    At 
December 31,  2015  and  2014,  we  had  borrowings  of  USD 406 million  and  USD 19 million,  respectively,  equivalent  to  approximately 
CHF 402 million  and  CHF 19 million,  respectively,  outstanding  under  the  revolving  credit  facility.    At  December 31,  2015  and  2014,  the 
variable interest rate on the outstanding borrowings was 2.25 percent. 

In  the  year  ended  December 31,  2014,  Transocean Inc.  also  declared  and  paid  to  us  an  aggregate  cash  dividend  of 

USD 825 million, equivalent to approximately CHF 817 million. 

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,  2015  and  2014,  we  recognized  such  costs  of  CHF 19 million  and  CHF 13 million, 
respectively, recorded in general and administrative costs and expenses, including personnel costs of CHF 19 million and CHF 8 million, 
respectively.

Note 10—Subsequent Event 

Qualified capital loss, par value reduction and own shares—On October 29, 2015, shareholders at our extraordinary general 
meeting 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 Par 
Value Reduction”) and the cancellation of all of our 2.9 million shares purchased under the share repurchase program.  The Par Value 
Reduction and the cancellation of shares became effective as of January 7, 2016 upon registration in the commercial register.  The Par 
Value  Reduction  effectively  remediated  the  qualified  capital  loss,  as  defined  in  Swiss  law,  presented  in  our  balance  sheet  as  of 
December 31, 2015. 

Norway  tax  investigations  and  trial  contingent  obligations—In  January 2016,  the  Norwegian  authorities  formally  and 
unconditionally dropped all criminal charges against our subsidiaries and the two employees related to the previously reported Norway tax 
investigations or trials.  All subsidiaries and external advisors have been fully acquitted on all criminal charges. 

Authorized  share  capital—  As  a  result  of  the  Par  Value  Reduction,  also  the  maximum  amount  of  CHF 337 million  available 
under  our  authorized  share  capital  approved  at  our  2014  annual  general  meeting  was  reduced  to  CHF 2 million.    Accordingly,  our 
authorized share capital authorizes the issuance of a maximum of 22.5 million fully paid in shares with a par value of CHF 0.10 per share. 

On February 15, 2016, our board of directors announced its proposal to seek shareholder approval at the 2016 annual general 
meeting  for  the  renewal  of  board  of  directors  authority  to  issue  shares  out  of  the  company’s  authorized  share  capital  for  a  maximum 
amount corresponding to approximately 6 percent of the company’s currently registered share capital for a two-year period.
