NOTICE OF 2017 ANNUAL GENERAL MEETING AND PROXY STATEMENT

COMPENSATION REPORT

2016 ANNUAL REPORT TO SHAREHOLDERS

ABOUT TRANSOCEAN LTD.
We are a leading international provider of offshore contract drilling services for oil and gas wells. As of 
February 9, 2017, we owned or had partial ownership interests in and operated a fleet of 56 mobile offshore 
drilling units. In addition, we have four newbuild ultra-deepwater drillships and five high-specification jackups 
under construction 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.

The rig symbols in the map above represent the company’s global market presence as of the February 9, 2017 Fleet Status Report.

ABOUT THE COVER
We will help our customers go beyond boundaries, in fields, anywhere in the world. We will take on challenges. We will achieve what is great. We will 
be Boundless.

The cover features one of our recent fleet additions, and most capable rigs in the world, the ultra-deepwater drillship Deepwater Proteus, currently 
operating in the U.S. Gulf of Mexico on a 10-year contract with Shell. The drillship was awarded Shell’s 2016 Global Floating Rig of the Year – an honor 
based on the rig’s HSE, crew and operational performance.

FORWARD-LOOKING STATEMENTS
Any statements included in this Proxy Statement and 2016 Annual Report that are not historical facts, including, without limitation, statements 
regarding future market trends and results of operations are forward-looking statements within the meaning of applicable securities law. Such 
statements are subject to numerous risks and uncertainties beyond our control and our actual results may differ materially from our forward-
looking statements.

Letter to Shareholders 

Despite  oil  prices  plummeting  below  U.S.  $30/bbl  during  the  first  quarter  of  2016,  resulting  in  the  further 
curtailing of customer spending and the early termination of a number of drilling contracts, our full year financial results 
once  again  exceeded  expectations.  We  are  pleased  that  our  continued  commitment  to  operational  excellence,  and  our 
intense focus on organizational and operational efficiency, resulted in another strong year for Transocean. 

As  we  enter  2017,  we  are  encouraged  by  the year-over-year  improvement  in  both  oil  prices  and  sentiment; 
however, we fully anticipate that the offshore drilling market will continue to prove challenging, as the combination of 
contract roll-overs and limited visibility to new demand will hinder, in the near-term, the meaningful advancement of both 
utilization and dayrates. In response, we continue to take the necessary actions to maintain our market leadership position 
as well as strategically position the company to emerge from the downturn leaner and stronger. 

We  continue  to  strengthen  our  financial  position.  We  successfully  executed  multiple  financing  transactions 
during  the year  that  strengthened  our  liquidity  and  balance  sheet.  These  actions  provide  both  protection  against  the 
possibility  of a  protracted  downturn,  and  strategic optionality, while preserving  shareholder  value.  In 2016,  we  issued 
approximately U.S. $2.5 billion of debt maturing in 2023 and 2024, while retiring U.S. $2.3 billion of debt with maturities 
between 2016 and 2022. We further deferred the delivery of seven newbuild assets into 2020, which delayed approximately 
U.S.  $2  billion  of  shipyard  payments.  And  lastly,  we  acquired  the  outstanding  interest  in  Transocean  Partners  LLC, 
eliminating administrative costs and a significant quarterly cash distribution. As a result of these transactions, and our 
outstanding  operational  performance,  along  with  U.S.  $3.1  billion  of  cash  and  a  U.S.  $3  billion  undrawn  unsecured 
revolving credit facility, we exited 2016 with substantial liquidity to both operate through the downturn and pursue value-
enhancing opportunities. 

We  continue  to  execute  our  commercial  strategy.  Even  in  the  face  of  this  difficult  market,  we  successfully 
executed multiple new contracts in 2016. Over the course of the year, Transocean won approximately a third of the global 
floater contracts awarded. This was due in part to our willingness to consider flexible contracting arrangements, including 
performance-driven models. Of note, we secured during the recent downturn our second contract for a previously cold-
stacked floater when our competitors’ hot rigs were ready and available. We view this as a testament to our customer 
relationships, our operating performance, and the trust that our customers have in our ability to reactivate rigs and crews. 
As of February 9, 2017, our backlog totaled U.S. $11.3 billion comprised of industry leading contracts with primarily 
investment grade customers. 

We remain committed to operational excellence and organizational and operational efficiency. In 2016, we 
continued to systematically drive improvements in safety, delivering the lowest annual Total Recordable Incident Rate in 
the company’s history. For the year, we also delivered Transocean’s highest annual average uptime and revenue efficiency 
performance,  further  demonstrating  the  direct  correlation  between  safety,  efficiency  and  shareholder  value.  And,  we 
achieved these milestones while simultaneously simplifying and streamlining our organization and our processes, resulting 
in year-over-year margin enhancement despite a sharp decline in revenue. 

We continue to high-grade our fleet. In 2016, we added three newbuild ultra-deepwater drillships, which are 
among the most technically capable rigs in the world. The first two, the Deepwater Thalassa and the Deepwater Proteus, 
commenced ten-year contracts with Shell in the U.S. Gulf of Mexico. To date, both assets have performed exceptionally 
well, with the Deepwater Proteus being awarded Shell’s 2016 Global Floating Rig of the Year. We take great pride in this 
distinction,  especially  since  this  is  the  ship’s  first year  of  operation.  The  third  newbuild  ultra-deepwater  drillship,  the 
Deepwater Conqueror, joined the fleet at the end of 2016, and is now on contract with Chevron for five years in the U.S. 
Gulf of Mexico. We look forward to the delivery of two additional ultra-deepwater drillships, which both have ten-year 
contracts  with  Shell.  The  Deepwater  Pontus  is  scheduled  for  delivery  later  in  2017,  and  the  Deepwater  Poseidon  is 
expected to join the fleet early in 2018. 

 
 
While certainly not as exciting as welcoming state-of-the-art new rigs into our fleet, part of our high-grading 
process includes the continued recycling of older, less-capable and less-marketable assets. In 2016, we retired another 
seven assets, bringing our total floater retirements over the past three years to 31. 

We continue to identify and realize opportunities to further differentiate ourselves. While the capability of our 
assets and the overall composition of our fleet are both critically important, we recognize that our greatest competitive 
advantages are our people and our processes and the way that we operate the company’s assets. Using our vast library of 
historical drilling data, we are identifying best practices to maximize efficiencies across crews and rigs to minimize the 
time spent drilling each well. Additionally, we have worked both independently and with suppliers to reengineer practices 
that reduce costs, downtime and shipyard stays. This includes condition, versus calendar-based, maintenance activities 
that reduce operating costs, and increase uptime, including lengthening the time between costly special periodic surveys. 
As we move through 2017, we will continue to build upon the foundation laid last year, leveraging data and technology to 
drive performance improvement across the enterprise. 

While we expect 2017 to be challenging, we believe that it should mark the trough in contracting activity. Global 
energy demand remains strong. As inevitable supply declines occur, and related energy prices improve, the market will 
require incremental production from the world’s deepwater oil and gas fields. Furthermore, the integrated oil companies, 
who have the greatest exposure to the offshore market, and specifically in deepwater, recognize that their future production 
is dependent upon developing their offshore fields. They also recognize that 2017 will mark the third consecutive year of 
under-investment in the vast majority of their offshore programs. Additionally, by 2018, offshore industry participants will 
have invested another 12 months into identifying and realizing additional efficiencies that should improve performance 
and  the  overall  economics  of  offshore  exploration  and  development.  Therefore,  we  remain  confident  that  there  will 
ultimately be a recovery that will result in incremental demand for our industry-leading assets and services. Until that time, 
we will continue to take the necessary steps to enhance our industry-leading position. 

Again, we want to thank you, our shareholders, on behalf of the entire team at Transocean. Your trust in our 

ability to run this great company is appreciated and never taken for granted. 

Sincerely, 

Merrill A. “Pete” Miller, Jr. 
Chairman of the Board of Directors

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 5) and Frederico F. Curado, Vincent 
J. Intrieri, Martin B. McNamara and Tan Ek Kia as members of the Compensation Committee (Agenda Item 6) to serve 
until  completion  of  the  2018  Annual  General  Meeting.  Note that  under  the  Minder  Ordinance  and  our  Articles  of 

iv 

 
 
 
 
 
 
 
 
 
     
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Association,  if  any  of  these  individuals  were  to  resign  or  there  were  vacancies  in  the  office  of  the  Chairman  or  the 
Compensation Committee for other reasons, the Board of Directors would have the authority to replace him or her with 
another member of the Board of Directors for a term expiring at the next Annual General Meeting. 

Pursuant to the Minder Ordinance, the Company is not permitted to appoint a corporate representative to act as 
the proxy for purposes of voting at the 2017 Annual General Meeting. Swiss companies may only appoint an independent 
proxy for these purposes. At the 2016 Annual General Meeting, shareholders elected Schweiger Advokatur / Notariat to 
serve as our independent proxy for the 2017 Annual General Meeting. Agenda Item 7 asks that you again elect this firm 
to  act  as  the  independent  proxy  for  the  2018  Annual  General  Meeting  and  any  extraordinary  general  meeting  of 
shareholders of the Company that may be held prior to the 2018 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 2017 Annual General Meeting 
and the 2018 Annual General Meeting (Agenda Item 10A) and the maximum aggregate amount of compensation of the 
Executive Management Team for fiscal year 2018 (Agenda Item 10B). The shareholder vote is binding. 

Features of Executive Compensation Program 

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

Record Date 

Only shareholders of record on April 24, 2017, are entitled to notice of, to attend, and to vote or to grant proxies 
to vote  at,  the 2017  Annual General  Meeting. No  shareholder will be  entered  in  Transocean Ltd.’s  share register with 
voting rights between the close of business on April 24, 2017, and the opening of business on the day following the 2017 
Annual General Meeting. 

While  no  shareholder  will  be  entered  in  Transocean Ltd.’s  share  register  as  a  shareholder  with  voting  rights 
between the close of business on April 24, 2017, and the opening of business on the day following the 2017 Annual General 
Meeting, share blocking and re-registration are not requirements for any shares of Transocean Ltd. to be voted at the 
meeting, and all shares may be traded after the record date. Computershare, which maintains Transocean Ltd.’s share 
register, will continue to register transfers of Transocean Ltd. shares in the share register in its capacity as transfer agent 
during this period. 

Quorum 

Our Articles of Association provide that the presence of shareholders, in person or by proxy, holding at least a 
majority of all the shares entitled to vote at the meeting constitutes a quorum for purposes of convening the 2017 Annual 
General Meeting and voting on all of the matters described in the notice of meeting. Abstentions and “broker non-votes” 
will be counted as present for purposes of determining whether there is a quorum at the meeting, so long as the broker has

(1)      Affirmative vote of a relative majority of the votes cast in person or by proxy at the 2017 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 a plurality of the votes cast in person or by proxy at the 2017 Annual General Meeting. The plurality requirement 
means that the nominee who receives the largest number of votes for a board position, or the chair or a position on the Compensation 
Committee, as applicable, is elected to that position. Only votes “FOR” are counted in determining whether a plurality has been cast in 
favor of a nominee. Abstentions, broker non-votes, blank or invalid ballots are not counted for such purposes and shall have no impact on 
the election of such nominees. As described later in this proxy statement, our Corporate Governance Guidelines set forth our procedures if 
a nominee is elected but does not receive more votes cast “FOR” than “AGAINST” the nominee’s election. 

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

(4)      The proposal is an advisory vote; as such, the vote is not binding on the Company. For the purposes of the proposal included in Agenda 
Item 11, which provides for an advisory vote on whether the advisory vote on the compensation of our Named Executive Officers should 
occur every one, two, or three years, the approval of an alternative requires the affirmative vote of a majority of the votes cast in person or 
by proxy at the 2017 Annual General Meeting, not counting abstentions, broker non-votes or blank or invalid ballots. If none of the 
alternatives (one year, two years or three years) receive a majority vote, we will consider the alternative with the highest number of votes 
cast by shareholders to be the alternative that has been selected by shareholders. 

Outstanding Shares 

As  of  March 1,  2017,  there  were  390,921,062  Transocean Ltd.  shares  outstanding,  which  exclude  3,880,928 
issued shares that are held by our subsidiaries. Only registered holders of our shares on April 24, 2017, the record date 
established for the 2017 Annual General Meeting, are entitled to notice of, to attend and to vote at, the meeting. Holders 
of shares on the record date are entitled to one vote for each share held. 

Voting Procedures 

A copy of the Notice of Internet Availability of Proxy Materials has been sent to each shareholder registered in 
Transocean Ltd.’s  share  register  as  of  the  close  of  business  on  March 16,  2017.  Any  additional  shareholders  who  are

the share register as of March 16, 2017, will receive a copy of the proxy materials, including a proxy card, after April 24, 
2017. Shareholders not registered in Transocean Ltd.’s share register as of April 24, 2017, will not be entitled to attend,

Under New York Stock Exchange (“NYSE”) rules, brokers who hold shares in street name for customers, such 
that the shares are registered on the books of the Company as being held by the brokers, have the authority to vote on 
“routine” proposals when they have not received instructions from beneficial owners, but are precluded from exercising 
their  voting  discretion  with  respect  to  proposals  for  “non-routine”  matters.  Proxies  submitted  by  brokers  without 
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:

Team from Liability for Activities During Fiscal Year 2016

forth above and may not be able to vote your shares on other matters at the 2017 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 2017 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 2 

Discharge of the Members of the Board of Directors and the Executive Management Team from Liability for 
Activities During Fiscal Year 2016. 

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 and John B. Stobart, who served as members of our Executive Management Team in 2016, be discharged from 
liability for activities during fiscal year 2016. 

Explanation 

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

Discharge pursuant to the proposed resolution is only effective with respect to facts that have been disclosed to 
shareholders (including through any publicly available information, whether or not included in our filings with the SEC) 
and only binds shareholders who either voted in favor of the proposal or who subsequently acquired shares with knowledge 
that shareholders have approved this proposal. In addition, shareholders who vote against this proposal, abstain from voting 
on this proposal, do not vote on this proposal, or acquire their shares without knowledge of the approval of this proposal, 
may bring, as a plaintiff, any claims in a shareholder derivative suit within six months after the approval of the proposal. 
After  the  expiration  of  the  six-month  period,  such  shareholders  will  generally  no  longer  have  the  right  to  bring,  as  a 
plaintiff, claims in shareholder derivative suits against members of the Board of Directors or Executive Management Team 
with respect to activities during fiscal year 2016. 

Recommendation 

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

AGENDA ITEM 3 

Appropriation of the Accumulated Loss for Fiscal Year 2016. 

Proposal of the Board of Directors 

The Board of Directors proposes that the accumulated loss of the Company be carried forward. 

Appropriation of Accumulated Loss 
Balance brought forward from previous years 
Reduction of par value 
Net loss of the year 
Total accumulated loss 
Appropriation of Accumulated Loss 
Balance to be carried forward on this account 

Explanation 

in CHF 
thousands 

(8,682,993)
3,750,000 
(64,039)
(4,997,032)

(4,997,032)

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  2017  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  the  following:  (a) a 
reduction of the par value of each share of the Company from CHF 15 to CHF 0.10, (b) 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  (c) 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. Accordingly, the CHF 3.75 billion reduction of our accumulated loss was not reflected in the accumulated loss as 
of December 31, 2015. The total accumulated loss as of December 31, 2016, reflects the loss that was carried forward 
from previous years, the reduction of par value and the net loss for the year ended December 31, 2016. 

The Board of Directors proposes that the entire accumulated loss of CHF 4,997,032,000 be carried forward. 

Recommendation 

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

AGENDA ITEM 4 

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  60  in  our  global  workforce.  We  have  a 
presence in over 25 countries worldwide. 

Voting Requirement to Elect Nominees 

The election of each nominee requires the affirmative vote of a plurality of the votes cast in person or by proxy 
at the 2017 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 by selecting the Governance page in the Investors’ section dropdown. 

The Board of Directors has received from each nominee for election at the 2017 Annual General Meeting listed 
below,  an  executed  irrevocable  letter  of  resignation  consistent  with  these  guidelines  described  above.  Each  letter  of 
resignation  is  effective  only  in  the  event  that  (1) such  director  fails  to  receive  a  sufficient  number  of  votes  from 
shareholders in an uncontested election of such director and (2) the Board of Directors accepts such resignation. 

The information regarding the nominees presented below is as of March 16, 2017.

and attest services related to financial reporting.

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 2016 other than the audit of our financial statements and reviews of quarterly 
financial statements was compatible with maintaining the independence of Ernst & Young LLP and determined that the 
provision of such services was compatible with maintaining such independence. 

The  Audit  Committee  has  adopted policies  and procedures  for pre-approving  all  audit  and non-audit  services 
performed  by  the  independent  registered  public  accounting  firm.  The  policy  requires  advance  approval  by  the  Audit 
Committee of all audit and non-audit work; provided, that the Chairman of the Audit Committee may grant pre-approvals 
of audit or non-audit work, so long as such pre-approvals are presented to the full Audit Committee at its next scheduled 
meeting. Unless the specific service has been previously pre-approved with 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 2017. Requests for services that have received this pre-approval are subject to specified fee or budget 
restrictions, as well as internal management controls.

AGENDA ITEM 9 

Advisory Vote to Approve Named Executive Officer Compensation. 

Proposal of the Board of Directors 

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  2017  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  results  or  if  the  Compensation  Committee  determines  that  an  executive  has  engaged  in,  or  has 
knowledge of and fails to prevent or disclose, fraud or intentional misconduct pertaining to any financial 
reporting requirements. 

The vote on this proposal is advisory and therefore not binding on the Company, the Compensation Committee 
or the Board of Directors. The Board of Directors and the Compensation Committee value the opinions of our shareholders. 
Following  the  2017  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.

member of the Board of Directors for fiscal year 2016 are disclosed under “2016 Director Compensation” and in our Swiss 
Compensation Report under the caption “Board of Directors’ Compensation.” 

Proposal for Ratification of Maximum Aggregate Amount 

The  Board  of  Directors  proposes  that  the  shareholders  ratify  an  amount  of  U.S.  $4,121,000  as  the  maximum 
aggregate amount of compensation of the Board of Directors for the 2017/2018 Term. This amount is the maximum amount 
that  the  Company  can  pay  or  grant  to  the  members  of  the  Board  of  Directors  for  the  2017/2018  Term.  The  proposed 
aggregate maximum amount has been calculated based on the directors’ compensation elements as outlined above. 

The table below shows the aggregate compensation paid to our Board of Directors for the 2015/2016 Term, and 
the shareholder-approved, maximum aggregate compensation payable to our Board of Directors for the 2016/2017 Term. 
The 2015/2016 Term and the 2016/2017 Term includes 10 non-employee directors, one of whom was Chairman of the 
Board of Directors. Further, the table explains our proposal for the maximum aggregate amount of compensation for our 
Board  of  Directors  for  the  2017/2018  Term.  This  proposal  is  unchanged  from  the  maximum  aggregate  compensation 
proposed for the 2015/2016 Term and 2016/2017 Term, which were previously approved by our shareholders, and includes 
consideration for 10 non-employee directors, one of whom will be Chairman and one of whom may be Vice-Chairman.

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 2014-2016 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,  2014  and  2015,  the 
shareholder approval levels have been 86%, 81%, 92%, 80% and 87%, respectively. Our shareholders are again provided 
the opportunity to cast a retrospective advisory vote to approve the compensation paid to our Named Executive Officers 
(including our Executive Management Team members) for fiscal year 2016, as is explained in detail in Agenda Item No. 9. 

The proposed maximum aggregate amount of compensation for the Executive Management Team for fiscal year 
2018  is  derived  substantially  from  the  Company’s  executive  compensation  principles  receiving  strong  historical 
shareholder support as noted above. Consistent with the Company’s historical practice in setting executive compensation, 
as reflected in the Compensation Discussion and Analysis, we do not anticipate that the aggregate amount actually paid to 
our Executive Management Team members for fiscal year 2018 will be at the proposed maximum aggregate amount. 

Proposal for Ratification of Maximum Aggregate Amount 

The Board of Directors proposes that the shareholders ratify an amount of U.S. $24,000,000, excluding employer-
paid social taxes, as the maximum aggregate amount of compensation of the Executive Management Team for fiscal year 
2018. This amount represents a reduction in the approved maximum aggregate amount of compensation of approximately 
20% over fiscal years 2016 and 2017, and is the maximum amount that the Company can pay or grant to its members of 
the Executive Management Team for fiscal year 2018, 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 2017 Annual 
General Meeting. This reduction is due, in part, to the amount of base salary and the incentive compensation opportunities 
of  our  Executive  Management  Team  incumbents  and  the  expectation  that,  effective  in  fiscal year  2018,  none  of  the 
Executive Management Team will receive expatriate-related compensation. 

The table below shows the maximum aggregate amount of compensation that could have been paid or granted in 
the  fiscal year  2016  under  our  compensation  principles  and  plans,  the  maximum  aggregate  amount  of  compensation 
available to be paid or granted for fiscal year 2017 under our compensation principles and plans currently in effect, and 
our proposed maximum aggregate amount of compensation for fiscal year 2018. 

The  proposed  maximum  aggregate  amount  of  compensation  for  fiscal year  2018  is  based  on  our  estimated 
compensation levels and represents a U.S. $5,600,000 reduction from the maximum aggregate amount of compensation 
for fiscal year 2017, 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 
plans, the fair value calculations are based on an assumed achievement of performance targets at 100%; see note 6 below for 
further information. 

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

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

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

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

(5)      Based on individual target award opportunities and maximum payout at 200%. As further described under “Compensation 

Discussion and Analysis—Annual Performance Bonus,” the potential payout ranges from 0% to 200% of the individual target 
award opportunity. Maximum payout is only available upon achievement of superior performance. Individual target award 
opportunities ranged, and will range, between 85% and 120% of the base salary, depending on the level of responsibility. 

(6)      Based on target amounts and fair value calculations. With regard to performance-based long-term incentives such as performance 
share units, the fair value calculations are based on an assumed achievement of performance targets at 100%. The actual number 
of shares to be allocated under such long-term incentive plans will be determined in 2021 depending on performance achievement 
over a three-year performance cycle and may range between 0-200%. 

(7)      Assumes that all compensation has been paid or granted at the maximum level as provided under our compensation principles and 
plans. Mandatory employer-paid social taxes pursuant to applicable law are excluded from the proposed maximum amount. In 
2016, employer-paid social taxes totaled U.S. $160,962. 

Shareholder approval is based on the maximum aggregate amounts that could be payable in accordance with our 
compensation principles as set out in the 2017 Proxy Statement’s “Compensation Discussion and Analysis.” Therefore, 
actual aggregate amounts paid to our Executive Management Team members for fiscal year 2018 will fall within the range 
that may be payable. And although historical compensation paid to our Executive Management Team, as disclosed in the 
Compensation Report, has been substantially less (2016: U.S. $18,328,330) than the maximum amount payable (2016: 
U.S. $29,023,000) we request our shareholders approve the proposed maximum aggregate amount in order to ensure that 
the authorized compensation is set at a level that allows us to honor our compensation obligations and promises under our 
compensation  principles  and  plans  if  the  Executive  Management  Team  or  its  individual  members  deliver  superior 
performance and achieve all of the performance objectives at maximum performance level. 

The 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.

AGENDA ITEM 11. 

Advisory Vote on the Frequency of Executive Compensation Vote 

Proposal of the Board of Directors 

As required by Section 14A of the Securities Exchange Act, the Board of Directors proposes that shareholders be 
provided with an advisory vote on whether the advisory vote on the compensation of the Company’s Named Executive 
Officers should occur every one, two or three years. 

Explanation 

The Company is presenting this proposal to give you, as a shareholder, the opportunity to inform the Company 
as to how often you wish the Company to hold an advisory vote on executive compensation. While our Board of Directors 
intends to carefully consider the shareholder vote resulting from the proposal, the final vote will not be binding on us and 
is advisory in nature. 

We  recommend  that  a  non-binding  advisory  vote  on  the  compensation  of  our  Named  Executive  Officers  as 
disclosed in our proxy statement for our annual general meeting be held every year. We believe holding that vote every 
year provides the most effective timeframe because it will provide our shareholders a consistent and clear communication 
channel for shareholder concerns about our executive pay programs. In the future, we may determine that a less frequent 
advisory vote is appropriate, either in response to the vote of our shareholders on this Agenda Item 11 or for other reasons. 

Voting Requirement to Approve Advisory Proposal 

Shareholders  are  being  asked  to  provide  an  advisory  vote  on  whether  the  non-binding  advisory  vote  on  the 
approval of the compensation of the Named Executive Officers should be held every one, two or three years. The approval 
of an alternative requires the affirmative vote of a majority of the votes cast in person or by proxy at the 2017 Annual 
General Meeting. If none of the alternatives (one year, two years or three years) receive a majority vote, we will consider 
the  alternative  with  the  highest  number  of  votes  cast  by  shareholders  to  be  the  alternative  that  has  been  selected  by 
shareholders. 

Recommendation 

The  Board  of  Directors  recommends  that  you  vote  to  hold  an  advisory  vote  on  executive  compensation 

EVERY YEAR. 

P-24 

 
 
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 November 2016, the Board of Directors adopted a Code of Integrity that updated and replaced our previous 
Code of Integrity. 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  by  selecting  the 

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

•  Articles of Association;

•  Our Mission Statement; 

•  Our FIRST Shared Values; and 

•  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. 

P-25 

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

Risk Management. Executive management is responsible for the day-to-day management of the risks we face, 
while the Board of Directors, as a whole and through its various committees, has responsibility for the oversight of risk 
management for the Company. Through the Board of Directors’ oversight role and review of management’s active role, 
the directors satisfy themselves that the risk management processes designed and implemented by management (as more 
particularly  described below)  are  adapted  to  and  integrated  with  the  Company’s  corporate  strategy, are  functioning  as 
designed and that steps are taken to foster a culture in which each employee understands his or her impact on the assessment 
and management of risk, his or her responsibility for acting within appropriate limits, and his or her ultimate accountability. 

The Company has 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  2016,  the  Compensation  Committee  considered  the  attributes  of  our 
programs, including the metrics used to determine incentive awards, the weight of each metric, the timing and processes 
for setting performance targets and validating results, the performance measurement periods and time horizons, the total 
mix of pay and the maximum compensation and incentive award payout opportunities. 

Independence of Board Members. Our Corporate Governance Guidelines require that at least a majority of the 
members  of  the  Board  of  Directors  meet  the  independence  standards  set  by  the  NYSE.  In  order  to  meet  the  NYSE’s 
independence standards, a member of the Board of Directors must not have a relationship with the Company that falls 
within certain objective categories established by the NYSE. In addition, the Board of Directors must then affirmatively 
determine, with respect to each director and nominee, that he or she did not otherwise have a material relationship with 
the Company. 

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

In  making  its  independence  determinations,  the  Board  of  Directors  considered  the  fact  that,  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 

P-26 

that provides legal services to the Company, and Mr. Barker’s son has been working as an associate auditor at PwC UK, 
an assurance, advisory and tax services firm that provides 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 2012, Mr. Barker has served as a director and member of Aviva’s 
audit committee, and from July 2015 until December 2016, as chairman of the board of directors of, Transocean Partners, 
formerly  a  publicly-held  subsidiary  of  Transocean  Ltd.  to  which  we  provided  operating,  support  and  administrative 
services, in addition to being the majority unitholder. Transocean Partners merged into a subsidiary of the Company in 
December 2016 and is now indirectly wholly-owned by the Company. 

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 Mr. Merksamer’s prior affiliation with Carl Icahn and certain investment funds managed by Mr. 
Icahn that formerly owned approximately 6% of the Company’s shares, from 2013 to 2015, Mr. Merksamer served as a 
non-executive director of Talisman Energy, from which we received revenues for performing services, and, since 2014, 
Mr. Merksamer has served as a director of Hertz Global Holdings, Inc., from subsidiaries of which the Company procures 
car  rental  services.  Since  May  2016,  Mr.  Merksamer  has  served  as  non-executive  director  of  American  International 
Group, Inc., a company that provides insurance-related services to the Company. Mr. Merksamer was a member of the 
board of directors of Transocean Partners from 2014 until 2016. 

In addition to Mr. Intrieri’s prior 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. 

Executive  Sessions.  Our  independent  directors  met  in  executive  session  without  management  at  each  of  the 
regularly scheduled Board of Directors’ meetings held in 2016. During 2017, the independent directors are again scheduled 
to meet in executive session at each regularly scheduled Board of Directors’ meeting. The independent directors generally 
designate the Chairman of the Board of Directors to act as the presiding director for executive sessions. 

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

P-27 

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.  For  purposes  of  our  Corporate  Governance  Guidelines,  an 
uncontested election occurs in an election of directors that does not constitute a contested election, and a contested election 
occurs when (i) the Secretary of the Company receives a notice that a shareholder has nominated a person for election to 
the Board of Directors in compliance with the advance notice requirements for shareholder nominees for director set forth 
in our Articles of Association and (ii) such nomination has not been withdrawn by such shareholder on or prior to the day 
next preceding the date the Company first mails its notice of meeting for such meeting to the shareholders. 

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

The  Corporate  Governance  Committee  considers  nominees  for  director  who  are  recommended  by  our 

shareholders. Recommendations may be submitted in writing, along with: 

• 

• 

• 

• 

• 

• 

• 

• 

the name of and contact information for the candidate; 

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

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

a signed statement of the proposed candidate consenting to be named as a candidate and, if nominated and 
elected, to serve as a director; 

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

a statement that the writer is a shareholder and is proposing a candidate for consideration by the Corporate 
Governance Committee; 

a statement detailing any relationship between the candidate and any customer, supplier or competitor of 
ours; 

financial and accounting experience of the candidate, to enable the Corporate Governance Committee to 
determine whether the candidate would be suitable for Audit Committee membership; and 

P-28 

• 

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.” 

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

Director  compensation  is  set  by  the  Board  of  Directors  upon  a  recommendation  from  the  Compensation 
Committee. Since 2015, director compensation is also subject to shareholder approval at the Company’s annual general 
meetings. Each calendar year, the Compensation Committee reviews the compensation paid to our 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, and may request it be 
forwarded, retained or destroyed at the Board of Directors’ discretion. 

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

To identify related person transactions, each year we distribute and require our directors and officers to complete 
questionnaires identifying transactions with us in which the officer or director or their immediate family members have an 

P-29 

interest. Quarterly, our directors and officers must re-affirm in writing that the information previously provided in their 
questionnaires remains accurate and complete, and provide updates regarding any related person relationships that may 
have  arisen.  Our  Code  of  Integrity  further  requires  that  an  executive  officer  inform  the  Company  when  the  executive 
officer’s private interest interferes or appears to interfere in any way with our interests. In addition, the Board of Directors’ 
Corporate Governance Guidelines require that a director must immediately inform the Board of Directors or the Chairman 
of the Board of Directors in the event that a director believes he or she has an actual or potential conflict with our interests. 
Furthermore, under our Organizational Regulations, a director must disclose and abstain from voting with respect to 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 2016, 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).  Prior  to  joining  the  Company  in  2015,  Mr.  Thigpen  served  as  Senior  Vice 
President and Chief Financial Officer of National Oilwell Varco, Inc. (NYSE: NOV) from December 2012 to April 2015. 
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 2016, our purchasing activity with 
NOV and NOW Inc. represented less than 2% of each company’s reported gross revenues for such periods. 

Director Attendance at Annual General Meeting. We expect all of our directors to attend the 2017 Annual General 

Meeting. At the 2016 Annual General Meeting, all directors then serving on the Board of Directors were in attendance. 

Board Meetings and Committees 

During  2016,  the  Board  of  Directors  of  Transocean  Ltd.  held  four  meetings.  The  Board  of  Directors  and  the 
committees of the Board of Directors met at least once a quarter and the quarterly meetings generally occurred over a 
period of two days. Each of our directors attended at least 80% of the meetings following their election, including meetings 
of committees on which the director served. 

The Board of Directors has standing Audit, Compensation, Finance, Corporate Governance, and Health Safety 
and  Environment  Committees.  As  noted  above,  the  charters  for  these  committees  may  be  found  on  our  website  at 
www.deepwater.com  by  selecting  the  Governance  page  in  the  Investors’  section  dropdown.  In  addition,  the  Board  of 
Directors may from time to time form special committees to consider particular matters that arise. 

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

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

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;

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

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

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

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

Committee. 

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

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

P-31 

period. The Compensation Committee has further delegated authority to the Chief Executive Officer to determine whether 
an individual is disabled and/or to set applicable criteria for making such determination for purposes of the Company’s 
long-term  incentives  plans.  The  Compensation  Committee  is  notified  of  compensation  actions  made  by  the  Chief 
Executive Officer or the subcommittee at the meeting following the end of each calendar quarter in which such actions are 
taken. 

The current members of the Compensation Committee are Mr. Tan, Chairman, and Messrs. Curado, Intrieri and 

McNamara. The Compensation Committee met four times during 2016. 

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, 

Intrieri and Merksamer. The Finance Committee met four times during 2016. 

Corporate Governance Committee. The Corporate Governance Committee makes recommendations to the Board 
of Directors with respect to the nomination of candidates for election to the Board of Directors, how the Board of Directors 
functions and how the Board of Directors should interact with shareholders and management. It 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 four times during 2016. 

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 2016. 

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 

P-32 

or not the Audit Committee has an “audit committee financial expert” as a member. An “audit committee financial expert” 
is defined as a person who, based on his or her experience, possesses all of the following attributes: 

• 

• 

• 

• 

• 

an understanding of generally accepted accounting principles and financial statements; 

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

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

an understanding of internal control over financial reporting; and 

an understanding of audit committee functions. 

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

• 

• 

• 

• 

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

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

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

other relevant experience. 

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

Committee met eight times during 2016. 

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 served as 
President  and  Chief  Executive  Officer  of  Embraer  S.A.  from  2007  to  2016  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 their service on the Board of Directors. 

P-33 

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

In 2016, non-employee director compensation in U.S. dollars included the following fixed components: 

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

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

Environment Committee

(1)    Currently, the Company does not have any director serving in a Vice Chairman role. 

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

In addition, we pay or reimburse our directors’ travel and incidental expenses incurred for attending Board of 

Directors, committee and shareholder meetings and for other Company business-related purposes. 

2016 Director Compensation 

In 2016, each non-employee member of the Board of Directors received the compensation described above. 

At the Board of Directors meeting held immediately after the 2016 Annual General Meeting of our shareholders, 
the Board of Directors granted 20,173 restricted share units to each non-employee director (other than the Chairman) and 
31,220 restricted share units to the non-employee Chairman in aggregate value equal to U.S. $210,000 and U.S. $325,000, 
respectively, based upon the average of the high and low sales prices of our shares for the 10 trading days immediately 
prior to the date of grant (calculated at U.S. $10.41 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 Public Company Accounting Oversight Board. The Audit Committee considers the effectiveness of these processes 
and  the  independence  of  Ernst &  Young LLP  on  an  ongoing  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  by  selecting  the 
Governance page in the Investors’ section dropdown. 

As part of its oversight function for the year ended December 31, 2016, 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-36 

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, 2016, in the Company’s Annual Report on Form 10-K for such year filed with the SEC.

2016 Business Overview 

As a result of our strong revenue efficiency performance, continued progress on margin improvement initiatives, 
as well as our liquidity accomplishments, Transocean outperformed the peer group in 2016. These actions demonstrate the 
direct correlation between operational performance and shareholder value. 

2016 Relative Stock Performance 

Peers include: ATW, DO, ESV, NE, ORIG, PACD, RDC, SDRL 

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 operates one of the most versatile offshore drilling fleets 
in the world. 

As of February 9, 2017, Transocean owns, or has partial ownership interests in, and operates a fleet of 56 mobile 
offshore  drilling  units  consisting  of  30  ultra-deepwater  floaters,  seven  harsh-environment  semisubmersibles,  three 
deepwater semisubmersibles, six midwater semisubmersibles, and 10 high-specification jackups. In addition, the Company 
has  four  ultra-deepwater  drillships  and  five  high-specification  jackups  under  construction  or  under  contract  to  be 
constructed. 

Despite oil prices falling to below U.S. $30/bbl during the first quarter of 2016, resulting in the further curtailing 
of customer spending, and the early termination of a number of drilling contracts, our 2016 financial results again exceeded 
expectations.  We  are  pleased  that  our  continued  commitment  to  operational  excellence,  and  our  intense  focus  on 
organizational and operational efficiency, resulted in another strong year for Transocean. 

Recently,  we have been  encouraged by  the  improvement in  both oil  prices  and  sentiment;  however, we  fully 
anticipate that the offshore drilling market will continue to prove challenging in 2017. The combination of fewer contract 
roll-overs  and  limited  visibility  for  new  demand,  will  hinder,  in  the  near-term,  the  meaningful  advancement  of  both 
utilization  and  dayrates.  In  response,  the  Company  continues  to  take  the  necessary  actions  to  maintain  our  market 
leadership position, as well as to strategically position the Company to emerge from the downturn stronger. 

P-42 

 
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, SDRL 

In 2016, we continued to strengthen our liquidity and balance sheet, executing multiple financing transactions. In 
2016, we issued approximately U.S. $2.5 billion of debt maturing in 2023 and 2024, while retiring U.S. $2.3 billion of 
debt with maturities between 2016 and 2022. The Company further deferred the delivery of two ultra-deepwater drillships 
and five high-specification jackups into 2020, which delayed approximately U.S. $2 billion of shipyard payments. We also 
acquired the outstanding interest in Transocean Partners, eliminating administrative costs and a significant quarterly cash 
distribution. These actions, along with U.S. $3.1 billion of cash as of December 31, 2016, and a U.S. $3 billion undrawn, 
unsecured  revolving  credit  facility,  provide  protection  in  the  event  of  a  protracted  downturn,  and  preserve  strategic 
optionality and shareholder value. 

We executed several new contracts during 2016, adding approximately U.S. $520 million in contract backlog. 
Transocean’s willingness to consider a performance driven model, and other flexible contract arrangements, assisted in 
the Company being awarded approximately one third of the annual contracted global floater fixtures. As of February 9, 
2017, our backlog totaled U.S. $11.3 billion. 

We  delivered  another  year  of  strong  operating  results  in  2016  guided  by  our  continued  commitment  to 
streamlining and optimizing every aspect of our business. Our operating strategy led to strong revenue efficiency results 
for 2016 of 97.8%, up from 96.0% in 2015. 

During 2016, we added three new contract-backed, ultra-deepwater drillships to our fleet: Deepwater Thalassa, 
Deepwater  Proteus,  and  Deepwater  Conqueror.  Both  the  Deepwater  Thalassa  and  Deepwater  Proteus  have  10  year 
contracts with Shell in the U.S. Gulf of Mexico, and the Deepwater Conqueror has a five year contract with Chevron, also 
in the U.S. Gulf of Mexico. 

We  continued  to  drive year-over-year  improvements  in  our  safety  performance  in  2016  delivering  a  Total 

Recordable Incident Rate of 0.34, the best in the Company’s history. 

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. 

P-43 

 
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 ranged from below to above targeted and competitive market 
levels. Below-target results have been driven by the lack of appreciation in the Company’s share price and below-target 
total shareholder return relative to our peers, whereas more recent above-target results reflect our disciplined approach to 
the market downturn and our recent outperformance of competitors in the offshore drilling sector. 

The Summary Compensation Table reflects the grant-date fair value for share awards. However, 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.  The  more  recent,  in-process  long-term  performance  cycles,  however,  reflect  our  superior 
performance relative to offshore drilling peers, although these performance cycles remain at risk until their conclusion. 

The graph below illustrates the effect of our performance-based compensation programs on the total compensation of 
our Chief Executive Officer. 

(1) 

(2) 

Realized/realizable pay is defined as the compensation delivered or deliverable for each year calculated as of the end of the fiscal year, including: 
salary received, amounts actually paid under the annual incentive plan, payouts received under the performance unit plan (PSU) or, for performance 
periods still in progress, amounts that would be receivable if the PSU performance period ended 12/31/2016, the intrinsic (“in-the-money”) value 
of the stock options granted in the applicable year, and the value of time-based restricted share units (“RSUs”). 

For  Steven  Newman,  our  former  Chief  Executive  Officer,  the  value  of  2013  and  2014  RSUs  were  calculated  as  of  5/31/2015,  the  date  of  his 
separation from Transocean. For Mr. Thigpen, the value of RSUs was calculated as of 12/30/2016.

Figures for Mr. Thigpen for 2015 (hired in April, 2015) represent partial year base pay and annual bonus target and exclude cash sign-on award 
and replacement RSU award in consideration of forfeited equity awards from his previous employer.

2016 Compensation Program Overview 

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

compensation programs and compensation award levels for 2016. 

In  recognition  of  the  continuing  global  industry  downturn,  the  Compensation  Committee  gave  prudent 
consideration in developing target 2016 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: 

•  Freeze on base salaries for all executives for 2016 (as was the case in 2015). Further, base salaries have 

been again frozen for 2017; 

•  Freeze on target annual incentive opportunities for all of our Executive Officers for 2016 (as was the case 

in 2015). Further, targets have been again frozen for 2017; 

• 

Implemented cap on 2016-2018 performance award upside payout tied to declining absolute total 
shareholder return (“TSR”) performance; and 

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

effective January 1, 2017. 

These compensation actions reflect the continued downturn in the current market, while maintaining prudently 

designed, 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 
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. 

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

• 

• 

• 

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

aligning annual incentive compensation with financial and strategic objectives; and 

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

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

P-45 

 
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 total shareholder return performance of the Company. 

Compensation Peer Group 

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

The Compensation Peer Group for 2016 comprised the following companies: 

•  Anadarko Petroleum Corporation 
•  Apache Corporation 
•  Baker Hughes Incorporated 
•  BG Group plc 
•  Cameron International Corporation 
•  Canadian Natural Resources Limited 
•  Chesapeake Energy Corporation 
•  Devon Energy Corporation 

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

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

P-46 

 
 
 
 
 
 
 
 
 
 
 
During 2016, three companies (BG Group plc, Cameron International Corporation and Talisman Energy Inc.) fell 

out of this Compensation Peer Group due to corporate acquisitions. 

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 establishes 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. Beginning in 2016, the Compensation Committee refined the Performance Peer Group to focus on 
drillers to better align with our strategic business objectives. While the competition for executive talent spans a broader 
market as defined above in the section addressing the Compensation Peer Group, our Performance Peer Group is specific 
to those companies with expertise in technically demanding offshore drilling operations. The Performance Peer Group 
consists of: 

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

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

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.

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 
(except with respect to his own compensation), 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  2016,  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 2016 increases over the 2015 base salaries. 

Further, in February 2017, the Compensation Committee again elected to freeze base salaries in consideration of 

the continuing market downturn, resulting in no increases over the 2016 base salaries noted below. 

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

Our Performance Award and Cash Bonus Plan (the “Bonus Plan”) is a 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 2016, each Named Executive Officer had a potential payout range of 0% to 200% of 
his individual target award opportunity. The Compensation Committee established a 2016 target bonus opportunity for 
each of the following Named Executive Officers at the same target opportunity as established for 2015, and have further 
maintained  the  same  target  bonus  opportunities  again  in  2017.  The  2016  target  bonus  opportunity  for  each  Named 
Executive Officer, expressed as a percentage of base salary, is as follows:

2016 Bonus Structure 

The annual cash bonus structure is designed with a focus on financial, operational and safety performance. These 
three focus areas have a direct line of sight to annual company operational and financial results while maintaining a strong 
focus on personnel, industrial and environmental safety. During the current drilling sector down cycle, driven largely by 
commodity pricing beyond the Company’s control, this annual bonus structure is designed to focus on those areas where 
the Company can differentiate itself from our competitors and be well-positioned for the market recovery. 

The design of each measure, relative weighting, and construction of our threshold-target-maximum payout range, 

were derived from the Company’s 2016 business plan with a focus on continuous improvement. 

The  Compensation  Committee  considered  the  results  of  key  performance  areas,  specified  at  the  beginning  of 
2016, when determining the outcomes of the variable, performance-based compensation under the Performance Award 
and Cash Bonus Plan for our Named Executive Officers for 2016. 

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

achievement and is discussed in greater detail below.

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 2016 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. 

For 2016, the Compensation Committee measured our safety performance through a combination of components: 
Total Recordable Incident Rate (TRIR), Dropped Object Potential Severity (DPSR) and Operational Integrity (also referred 
to as “Process Safety”). TRIR and Process Safety were each weighted at 10%, with DPSR weighted at 5%. 

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

Operational Integrity. 

During  2016,  performance  results  across  all  three  safety  measures  established  new  company  records.  These 
results reflect an outstanding commitment to safety from our workforce and a relentless focus on continuous improvement 
toward an incident-free workplace. Together, the safety metric outcomes resulted in a formulaic payout percentage for 
Safety of 42% of the total target bonus opportunity for each of the Named Executive Officers in 2016.

Total Recordable Incident Rate (TRIR) 

TRIR is a safety performance metric recognized by the U.S. Occupational Safety & Health Administration and 
is  used  by  companies  across  an  array  of  industries.  We  calculate  TRIR  based  upon  the  guidelines  set  forth  by  the 
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 2016 of 0.39, representing further progress toward our 
zero  accident  safety  vision.  This  target  represented  an  improvement  of  8%  over  the  2015  actual  performance  which 
represented  the  best  TRIR  outcome  to  that  point  in  the  Company’s  history.  Values  above  and  below  this  target  were 
calculated in accordance with the chart below, with outcomes falling between the two boundaries interpolated on a straight-
line basis: 

TRIR Outcome to Target 
Maximum = 0.35 
Target = 0.39 
Minimum = 0.47 

Bonus Payout 
200%
100%
0%

Any  TRIR outcome  representing  a result of  0.47 or greater would result in  a 0%  bonus  payout for  the  TRIR 
metric,  representing  a  20%  negative  variance  from  target;  however,  if  2016  results  did  not  outperform  2015  actual 
performance, a 10% reduction would be applied to the formulaic payout for the TRIR component. TRIR results of 0.35, 
reflecting top quartile IADC performance, would result in a payout of 200% for the TRIR metric. 

Our TRIR outcome for 2016 was 0.34, exceeding maximum performance 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. 

Dropped Object Potential Severity (DPSR) 

DPSR is an internally developed safety measure that we utilize to capture the potential severity of incidents over 
a period of time. This 2016 safety measure represents a focus on continuous improvement. In 2015, the Company measured 
Total Potential Severity Rate, of which DPSR represented a significant component. Dropped objects from elevated heights, 
including tools, parts and equipment, have the potential to cause severe personnel injury and significant structural damage 
to the rig. Analysis indicated dropped object incidents typically have the highest potential severity to harm people working 
onboard our rigs. As such, we extracted this metric from TPSR in order to bring a more acute focus to dropped object 
prevention. Accordingly, the bonus measure reflects our focus on accident avoidance. 

The formulaic measure of DPSR evaluates the severity of all dropped objects and applies a score to each incident 
based on severity. This severity assessment follows prescribed guidelines defined in the Company’s Health and Safety 
Policies and Requirements. The sum of dropped object events is then measured against the total number of working hours, 
to determine the quantity and severity of events as a factor of total hours worked. This measurement technique, using total 
hours worked, is consistent with the methodology employed by OSHA and IADC in measuring work-related injuries.

The Compensation Committee approved a DPSR target for 2016 of 9.93, reflecting a 9% improvement over our 
2015 target and represents further progress toward our safety vision. Values above and below this target were calculated 
in accordance with the chart below, with outcomes falling between two boundaries interpolated on a straight-line basis: 

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

      Bonus Payout 

200%
150%
100%
50%
0%

Any DPSR outcome representing a shortfall of more than 20% as compared to the target would result in a 0% 
bonus payout for the DPSR 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 DPSR metric. 

Our DPSR outcome for 2016 of 8.33 represents the best performance in the Company’s history and a significant 
improvement as compared to the target. This improvement resulted in a formulaic result of 180.4% of target for the DPSR 
metric, and a formulaic result for this measure of 9% of the total target bonus opportunity for each of the Named Executive 
Officers. 

Operational Integrity (Process Safety) 

We  believe  that  in  addition  to  personnel  and  behavioral  safety,  prevention  and  mitigation  of  major  accident 
hazards  or  process  incidents  are  critical  components  of  a  comprehensive  safety  management  program.  Accordingly, 
Operational  Integrity  is  an  internally  developed  safety  measure  designed  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 Operational Integrity metric, we measure the number of process safety events that are likely 
predictors or leading indicators of a potentially significant major accident hazard event. The 2016 target for process safety 
events was established to represent an improvement over the baseline of events that occurred on our installations in 2015. 

The Compensation Committee approved an Operational Integrity target for 2016 of 0.42, reflecting improvement 
over 2015 actual results of 0.44 and representing further progress toward our safety vision. Values above and below this 
target were calculated in accordance with the chart below, with outcomes falling between two boundaries interpolated on 
a straight-line basis: 

Operational Integrity Outcome to Target

In 2016, the Operational Integrity measure realized an actual result of 0.09, resulting in 200% achievement of 
this metric and a formulaic result for this measure of 20%; however, the Operational Integrity measure calls for a one-third 
reduction in the formulaic payout result in the event of any Tier1 Operational Integrity event, as defined in the Company’s 
Health and Safety Policies and Requirements. A Tier1 event is the most serious Operational Integrity event, requiring 
immediate and potentially significant company time and resources to rectify.

In August 2016, Transocean experienced a Tier1 Operational Integrity event† that resulted in a reduction of the 
formulaic result for the Operational Integrity measure from 20% to 13.33% of the total bonus opportunity for each of the 
Named Executive Officers. 

† 

During severe weather on August 8, 2016, the tow to the Transocean Winner was lost and the rig subsequently grounded off the Western Isles of 
Scotland. Transocean personnel were immediately mobilized to recover the rig and mitigate impact. 

Financial Performance 

EBITDA 

For the 2016 bonus plan, the Compensation Committee determined Earnings Before Interest, Taxes, Depreciation 
and Amortization (“EBITDA”), a commonly accepted measure of financial performance, as the most appropriate measure 
to  align  with  the  Company’s  financial  objectives.  Weighted  at  50%  of  the  total  2016  annual  bonus  plan  opportunity, 
EBITDA replaces the prior 2015 bonus plan focus on Cash Flow Value Added and Operating Costs. Attached as Appendix 
A to this proxy statement is a reconciliation of EBITDA, a non-GAAP financial measure, to net income, the most directly 
comparable GAAP financial measure. 

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

In establishing the EBITDA target, the Compensation Committee considered the Company’s 2016 financial plan. 
Threshold and maximum performance outcomes were then set based on the potential for decreases or increases to financial 
outcomes tied to dynamic market conditions. 

EBITDA Target 
Threshold 
Target 
Maximum 

      Achievement (MM-$) 

1,540
1,876
2,049

2016  EBITDA  results  were  challenged  by  declining  demand  for  rigs  combined  with  depressed  dayrates  for 
contracts. However, a strong focus on cost management combined with outstanding efficiency for deployed rigs, resulted 
in  actual  EBITDA  results  exceeding  the  target  for  this  measure.  EBITDA  results  achieved  161.3%  of  target,  and  a 
formulaic result for this measure of 80.64% of the total target bonus opportunity for each of the Named Executive Officers. 

The  EBITDA achievement  that was  applied  to  the  annual  bonus plan performance  achievement  was  adjusted 
downward to remove certain revenue associated with early contract terminations and other unanticipated events during the 
performance cycle; thus, EBITDA results applied to the annual bonus plan are lower than the financial results recorded in 
the Company’s financial statements. Without such downward adjustments to the bonus plan EBITDA results, actual bonus 
results would have been higher, potentially leading to the unintended consequence of higher incentive awards due to lower 
rig activity. 

P-53 

 
 
 
 
 
 
 
 
 
 
Uptime 

Uptime was identified as the operational performance measure that would best align with our customers’ interests 
during 2016. This measure represented 25% of the total target annual bonus opportunity to reinforce the importance of 
maintaining excellence in rig operations. While similar to Revenue Efficiency, a drilling rig’s measure of contract revenues 
used in the Company’s 2015 annual bonus plan, Uptime has a more direct focus on operational efficiency. 

Uptime  is  a  common  operational  metric  used  in  the  drilling  industry;  however,  there  is  no  standard  industry 
definition and reporting structure for this metric. Our Company’s definition recognizes both equipment failures and human 
performance errors in calculating a rig’s performance. 

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

In setting the threshold-target-maximum range for this measure, the mathematical differential across the range 
may  appear  small  (e.g.,  a 1.5%  spread  from  target  to  maximum  performance);  however,  this differential  is  significant 
considering the total number of operating hours during a calendar year. 

The Committee approved the following Uptime target for 2016: 

Uptime Target 
Threshold 
Target 
Maximum 

      Achievement    
94.0%  
95.5%  
97.0%  

In setting the 2016 performance range, management considered past performance and set stretch targets to focus 
on continuous improvement. While the Company strives for improvement year over year, consideration must be given to 
the Company’s fleet composition and business cycle in setting this target. Reduced fleet size, shorter contract durations, 
change  of  location  mobilizations  and  the  challenge  of  bringing  new  rigs  on  line  will  all  potentially  apply  downward 
pressure on a fleet’s Uptime performance. We experienced all of these challenges in 2016 and still delivered outstanding 
Uptime performance for our customers. 

Based on this high level of operational efficiency, the actual Uptime measure achieved 96.6%. This incremental 
1.1% above target performance, equates to approximately 3,300 hours, or 137.5 days, of additional operational productivity 
across the fleet. This achievement result represents 173.3% of target, and a formulaic result for this measure of 43.33% of 
the total target bonus opportunity for each of the Named Executive Officers. 

Actual Bonus Plan Compensation for 2016 

Based on the performance measures described above and using the pre-determined weightings assigned to each 
measure by the Compensation Committee, the formulaic bonus outcome for each of our Named Executive Officers was 

P-54

sharp  focus  on  financial  results,  while  maintaining  the  highest  standards  for  safety.  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, three types of long-term equity instruments 
were used in 2016, including Performance Units, Restricted Share Units and Non-Qualified Stock Options. The weighting 
of each instrument in our long-term incentive program was as follows: 

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

The forms of equity awards made to our Named Executive Officers are discussed in greater detail below.

Performance Units (PSU) 

Each PSU represents one share and is earned based on performance over a three-year performance cycle from 
January 1, 2016 through December 31, 2018. Performance is determined by comparing the Company’s TSR performance 
relative to the Company’s Performance Peer Group over the three-year performance cycle. 

In constructing this performance equity plan, the Compensation Committee considered the value of including an 
absolute financial measure, similar to the structure of the Company’s 2015 – 2018 performance plan which included Return 
on Capital Employed (“ROCE”) as a financial measure. After a thorough review of current market conditions and the 
substantial challenges in setting ROCE long-term incentive goals in an extremely volatile environment, the Committee 
concluded that a single measure of relative TSR using the Performance Peer Group of nine offshore drillers offered the 
best shareholder alignment and better supported the Company’s strategic objective of becoming the undisputed leader in 
offshore drilling. 

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

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

ranking of TSR performance:

Upon completion of the 2016 - 2018 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 2016 RSU grants to each of the Named Executive Officers was approximately one-quarter 

(25%) of each officer’s total 2016 long-term incentive award target value. 

Time-vested RSUs were granted to all Named Executive Officers as part of the 2016 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. 

Non-Qualified Stock Options 

The target value of the 2016 Non-Qualified Stock Options (“NQSO”) grants to each of the Named Executive 

Officers was approximately one-quarter (25%) of each officer’s total 2016 long-term incentive award target value. 

Time-vested NQSOs were granted to all Named Executive Officers as part of the 2016 annual long-term incentive 
grants. Each NQSO represents one share and vests over a three-year schedule (ratably one-third each year), contingent on 
continued service.

Realized Long-Term Incentive Compensation for 2016 

In 2017,  the  Compensation  Committee  evaluated  the  Company’s performance  for  the three-year performance 
period from January 1, 2014 through December 31, 2016, and determined the Company’s performance to be 123.3% of 
target. This result represents the first payout in seven performance cycles for the Company. 

This performance plan consisted of two measures, equally weighted at 50% of the total award opportunity. The 
two measures included relative TSR as measured against a performance peer group, and ROCE during the first year of the 
three year  performance  cycle.  Final  measurement  for  this  performance  cycle  included  ROCE  results  slightly  below 
maximum performance. Actual ROCE financial results are not disclosed due to the proprietary nature of this information 
in establishing the Company’s competitive position in the market. With respect to relative TSR, the Company ranked 8 of 
12  against  performance  peer  companies,  resulting  in  performance  below  target  for  this  measure.  The  two  measures 
combined resulted in the 123.3% of target performance outcome. 

Mr. Stobart is the only Named Executive Officer eligible for this 2014 – 2016 performance plan payout. When 
considering  the  Company’s  share  price  decline  during  this  three year  period,  however,  the  123.3%  achievement  level 
translates to approximately 39% of target in realizable value compared to the expected target value at grant. 

Employment Agreements with Named Executive Officers 

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

Expatriate Benefits 

For our Named Executive Officers who accept an international assignment, we 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. Beginning in 2014 the Named Executive 
Officers ceased to be eligible for tax protection or tax equalization on these expatriate benefits. Effective September 1, 
2016, Mr. Stobart was the only Named Executive Officer receiving the above-mentioned expatriate benefits. 

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. 

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 U.S. $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 

In 2016, the Compensation Committee elected to eliminate all executive perquisites for our Named Executive 

Officers, effective January 1, 2017.

Prior  to  elimination,  the  Company  offered  limited  perquisites  as  a  recruiting  and  retention  tool.  Each  of  our 
Named Executive Officers could receive reimbursement of up to U.S. $5,000 in financial planning consulting. Our Named 
Executive Officers were 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 2016. 

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 
award 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,  2016,  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 
benefits described above, the Named Executive Officer must first sign a release of all claims against the Company and 
enter into a non-competition and confidentiality agreement covering our trade secrets and proprietary information. 

The  Minder  Ordinance  prohibits  certain  types  of  compensation  payments  to  members  of  the  Executive 
Management Team, including severance payments in any form. Therefore, members of the Executive Management Team 
are  not  eligible  to  participate  in  the  executive  severance  benefits  policy.  Pursuant  to  their  employment  agreements, 
members  of  the  Executive  Management  Team  must  receive  at  least  twelve  months’  notice  prior  to  a  termination  of 
employment without cause. 

Executive Compensation Governance, Policy and Practice 

The  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. 

P-58 

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 recommending focus areas for our Chief Executive Officer for approval by the members of our 
Board of Directors who meet the independence and experience requirements set forth in the 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 long-term incentive plans, including determining plan eligibility and 
approving individual awards for all plan participants; 

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

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

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

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

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 2016. 

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 U.S. $100,000. Neither Pay 
Governance  nor  any  of  its  affiliates  provided  the  Company  with  any  other  services  in  2016.  In  May  2016,  the 
Compensation Committee assessed whether the work of Pay Governance for the Compensation Committee during 2016 
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. 

P-59 

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 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. 

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. 

P-60 

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. 

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  of  financial  results  or  if  the  Compensation  Committee 
determines that an executive has engaged in, or has knowledge of, and fails to prevent or disclose, fraud or intentional 
misconduct pertaining to any financial reporting requirement. 

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

recoupment of executive compensation. 

Tax Impact on Compensation 

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

Under the long-term incentive plan, 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.

This column shows the amount of cash payable to the Named Executive Officers under our Performance Award and Cash Bonus Plan. Actual 
amounts earned by the Named Executive Officers under the plan appear in the Non-Equity Incentive Plan Compensation Column of the Summary
Compensation Table. For more information regarding our Performance Award and Cash Bonus Plan, including the performance targets used for
2016, see “Compensation Discussion Analysis—2016 Bonus Structure.” 

The February 11, 2016, performance share unit award is subject to a three-year performance period ending December 31, 2018. The actual number 
of performance units received will be determined in the first 60 days of 2019 and is contingent on our performance in total shareholder return 
relative to the Performance Peer Group. Any earned shares will vest on December 31, 2018. For more information regarding long-term incentives 
plans, including the performance targets used for 2016 and the contingent nature of the long-term incentives granted, please see “Compensation
Discussion and Analysis—Long-Term Incentives.” 

This column shows the number of time-vested restricted share units and non-qualified stock options granted to the Named Executive Officers
under the long-term incentives plans. The units and options vest in one-third increments over a three-year period commencing on March 1, 2018,
and the anniversary of the date of grant, respectively. 

This column shows the exercise or base price of option awards granted to the Named Executive Officers as long-term incentives. 

This column represents the grant-date fair value of these awards calculated in accordance with accounting standards for recognition of share-based

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

Transocean U.S. Retirement Plan 

The Transocean U.S. Retirement Plan is a tax-qualified pension plan. Benefit accruals under this plan were frozen 

effective as of December 31, 2014. Mr. Stobart is the only the Named Executive Officer who participates in this plan. 

The purpose of the plan is to provide post-retirement income benefits to employees in recognition of their long-
term  service  to  the  Company.  Benefits  available  to  executives  are  no  greater  than  those  offered  to  non-executive 
participants.  The  plan  is  funded  through  cash  contributions  made  by  the  Company  based  on  actuarial  valuations  and 
regulatory requirements. Employees working for the Company in the U.S. are fully vested after completing five years of

eligible employment. Employees earn the right to receive a benefit upon retirement at the normal retirement age of 65 or 
upon early retirement (age 55 or older with five years of service). 

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

Certain assumptions and calculation methods were used to determine the values of the pension benefits disclosed 
in the Pension Benefits Table above. In particular, monthly accrued pension benefits, payable at age 65, were determined 
as of December 31, 2016. The present value of these benefits was calculated based on assumptions used in the Company’s 
financial statements for 2016. 

Transocean Pension Equalization Plan 

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

effective December 31, 2014. Mr. Stobart is the only Named Executive Officer with a frozen benefit in the PEP. 

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

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

Certain assumptions and calculation methods were used to determine the values of the pension benefits disclosed 
in the Pension Benefits Table above. In particular, monthly accrued pension benefits, payable at age 65, were determined 
as of December 31, 2016. The present value of these benefits was calculated based on assumptions used in the Company’s 
financial statements for 2016. 

Potential Payments Upon Termination or Change of Control 

The  following  tables  and  narrative  disclosure  set  forth  certain  information  with  respect  to  compensation  that 
would be payable to the Named Executive Officers, as of December 31, 2016, upon a variety of termination or change of 
control scenarios. 

As  of  December  31,  2016,  the  Named  Executive  Officers  of  the  Company  were  eligible  for  the  executive 
severance benefit policy. However, members of the Executive Management Team are further subject to the full limitations 
of the Minder Ordinance regarding severance.

(1)  Any involuntary not-for-cause termination as of December 31, 2016, 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)  Upon an involuntary, not-for-cause termination, all unvested, time-based restricted shares granted prior to 2016 and a pro-rata portion granted in 

2016 would vest. 

(4) 

(5) 

Performance-based Units (PSUs) are based upon the achievement of a performance standard over a three-year period. Upon an involuntary, not-
for-cause termination, the Named Executive Officers would receive a pro-rata portion of the earned PSUs. The performance achievement of the 
PSUs will be determined within 60 days of the end of each three-year performance period and the pro-rata portion of the earned PSUs is determined 
based on the period of time the Named Executive Officer was employed during the performance period. 

The amount of PEP and Savings Restoration Plan benefits included in the table represents the present value of those benefits which would have 
been payable as of December 31, 2016.

(1)  Restricted shares and deferred units are included in the awards we may grant as under the long-term incentive plans, and 3,732,575 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 Corporation in 2007, 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 U.S. $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 December 31, 2014, our directors held 18,156 and 
20,275 share equivalents under the plan, respectively.

Compensation Committee Interlocks and Insider Participation 

OTHER MATTERS 

The members of the Compensation Committee of the Board of Directors during 2016 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  2016,  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 2016 other than a Form 4 that was filed on behalf of Mr. Howard E. Davis, the Company’s 
Executive  Vice  President,  Chief  Administrative  Officer  and  Chief  Information  Officer,  on  November  16,  2016,  with 
respect to the vesting of certain restricted units on August 17, 2016. 

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  2018  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 5:00 p.m. Swiss time on November 17, 2017. However, if the date of the 
2018 Annual General Meeting changes by more than 30 days from the anniversary of the 2017 Annual General Meeting, 
the deadline is a reasonable time before we begin to print and mail our proxy materials. We will notify you of this deadline 
in a Quarterly Report on Form 10-Q, in a Current Report on Form 8-K or in another communication to you. Shareholder 
proposals must also be otherwise eligible for inclusion. 

P-71 

Shareholder Proposals and Nominations for Directors to be Presented at Meetings. If you desire to bring a matter 
before an annual general meeting and the proposal is submitted outside the process of Rule 14a-8, you must follow the 
procedures set forth in our Articles of Association. Our Articles of Association provide generally that, if you desire to 
propose any business at an annual general meeting (including the nomination of any director), you must give us written 
notice at least 30 calendar days prior to the anniversary date of the proxy statement in connection with Transocean’s last 
annual general meeting; provided, however, that if the date of the annual general meeting is 30 calendar days before or 
after the anniversary date of the last annual general meeting, such request must instead be made by the tenth day following 
the date  on  which  we  have made  public  disclosure of  the  date of  the  annual general meeting.  The deadline under  our 
Articles of Association for submitting proposals will be 5:00 p.m. Swiss time on February 15, 2018, for the 2018 annual 
meeting unless it is more than 30 calendar days before or after May 11, 2017. 

In  order  for  the  notice  to  be  considered  timely  under  Rule  14a-4(c) of  the  Exchange  Act,  proposals  must  be 
received no later than 5:00 p.m. Swiss time on February 15, 2018. The request must specify the relevant agenda items and 
motions,  together  with  evidence  of  the  required  shareholdings  recorded  in  the  share  register,  as  well  as  any  other 
information required to be included in a proxy statement pursuant to the rules of the SEC. 

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

• 

• 

• 

• 

• 

• 

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

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

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

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

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

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

The Board of Directors may refuse to transact any business 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 D.F. King & 
Co., Inc. (New York) for a fee of U.S. $15,000, 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-72 

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—2016  Business  Overview,” regarding future financial 
performance, results of operations, liquidity, stacking of assets and the market and other statements that are not historical 
facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of 
the Exchange Act. Forward-looking statements are subject to numerous risks, uncertainties and assumptions, including, 
but not limited to, the future prices of oil and gas, operating hazards and delays, actions by customers and other third 
parties, conditions in the drilling industry and in the capital markets and those described under “Item 1A. Risk Factors” in 
the 2016 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.

COMPENSATION REPORT 
For the years ended December 31, 2016 and 2015 

Ernst & Young Ltd 
Maagplatz 1 
P.O. Box 
CH-8010 Zurich 

To the General Meeting of 

Transocean Ltd., Steinhausen

Zurich, March 13, 2017 

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, 2016. 

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, 2016 of Transocean Ltd. complies with Swiss law and 

articles 14—16 of the Ordinance.

In  addition  to  the  directors’  compensation,  we  pay  or  reimburse  our  directors  for  travel  and  incidental  expenses  incurred  for 
attending  board,  committee  and  shareholder  meetings  and  for  other  company-related  business  purposes.    Our  directors  who  are  our
employees do not receive compensation for board service.  With the exception of Jeremy D. Thigpen, all of the directors on our Board of 
Directors  receive  compensation  as  non-employees.    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.  No director served in the position of 
non-executive vice chairman for the years ended December 31, 2015 and December 31, 2016. 

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

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

Share-based compensation 

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

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

In  the  years  ended  December 31,  2016  and  2015,  we  granted  performance  share  units  to  members  of  our  Executive 
Management Team.  Such performance share units are subject to a three-year performance period during which the actual number of units 
remain  uncertain.    The  number  of  performance  share  units  presented  below  represents  the  targeted  number  of  shares  awarded.    The
actual  number  of  share  units  earned  will  be  determined  in  the  first  60 days  following  the  performance  period  based  on  performance
thresholds and may range between zero and two shares per performance share unit. 

Share-based compensation awards were granted as follows:

“Company,”  “we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas  wells.    As  of 
February 9, 2017, we owned or had partial ownership interests in and operated 56 mobile offshore drilling units.  As of February 9, 2017, 
our  fleet  consisted  of  30 ultra-deepwater  floaters,  seven harsh  environment  floaters,  three deepwater  floaters,  six midwater  floaters  and 
10 high-specification jackups.  At February 9, 2017, we also had four 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 under the symbol “RIG” (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 21—Operating  Segments, 
Geographic Analysis and Major Customers.” 

Recent Developments 

Transocean Partners—On December 9, 2016, Transocean Partners LLC (“Transocean Partners”) completed a merger with one 
of  our  subsidiaries  as  contemplated  under  the  Agreement  and  Plan  of  Merger  (the  “Merger Agreement”),  dated  July 31,  2016,  and  as 
amended  on  November 21,  2016.    Following  the  completion  of  the  merger,  Transocean Partners  became  a  wholly  owned  indirect 
subsidiary of Transocean Ltd.  Each Transocean Partners common unit that was issued and outstanding immediately prior to the closing, 
other than the units held by Transocean and its subsidiaries, was converted into the right to receive 1.20 of our shares.  To complete the 
merger, we issued 23.8 million shares from conditional capital. 

Markets  for  our  shares—Our  shares  were  previously  listed  on  the  SIX  Swiss  Exchange  (“SIX”)  under  the  symbol  “RIGN”.  

Effective March 31, 2016, at our request, our shares were delisted from the SIX. 

Drilling Fleet 

Fleet  overview—Our  drilling 

including  drillships  and 
semisubmersibles,  and  (2) jackups.    Most  of  our  drilling  equipment  is  suitable  for  both  exploration  and  development,  and  we  normally 
engage in both types of drilling  activity.  All of our drilling rigs are mobile and can be moved to new locations in response to customer 
demand.  All of our mobile offshore drilling units are designed to operate in locations away from port for extended periods of time and have 
living quarters for the crews, a helicopter landing deck and storage space for drill pipe, riser and drilling supplies. 

fleet  can  be  generally  characterized  as 

follows:  (1) floaters, 

Drillships are generally self-propelled vessels, shaped like conventional ships, and are the most mobile of the major rig types.  All 
of our drillships are ultra-deepwater capable and equipped with a computer-controlled dynamic positioning thruster system, which allows 
them to maintain position without anchors through the use of their onboard propulsion and station-keeping systems.  These rigs typically 
have greater deck load and storage capacity than early generation semisubmersible rigs, which provides logistical and resupply efficiency 
benefits for customers.  Drillships are generally better suited to operations in calmer sea conditions and typically do not operate in areas 
considered  to  be  harsh  environments.    We  have  15 ultra-deepwater drillships  that  are,  and  four ultra-deepwater  drillships  under 
construction that will be, equipped with our patented dual-activity technology.  Dual-activity technology employs structures, equipment and 
techniques using two drilling stations within a dual derrick to allow these drillships to perform simultaneous drilling tasks in a parallel, rather 
than a sequential manner, 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, 
our four 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 

AR-2 

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  that  are  designed  for  mild 
environments and are equipped with the tri-act derrick.  The tri-act derrick, which was designed to reduce overall well construction costs 
since 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.    Five of  our  23 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 9, 2017, we owned and operated a fleet of 56 rigs, excluding rigs under construction, as follows: 
(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 

30 ultra-deepwater floaters; 
Seven harsh environment floaters; 
Three deepwater floaters; 
Six 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  approximately  30 days  following  initiation  of  stacking.    Some  idle  rigs  and  all 
stacked rigs require additional costs to return to service.  The actual cost to return to service, which in many instances could be significant 
and could fluctuate over time, depends upon various factors, including the availability and cost of shipyard facilities, cost of equipment and 
materials  and  the  extent  of  repairs  and  maintenance  that  may  ultimately  be  required.    We  consider  these  factors,  together  with market 
conditions, length of contract, dayrate and other contract terms, when deciding whether to return a stacked rig to service.  We may, from 
time to time, consider marketing stacked rigs as accommodation units or for other alternative uses until drilling activity increases and we 
obtain drilling contracts for these units.  We may not return some stacked rigs to work for drilling services or for these alternative uses. 

Drilling  units—The  following  tables,  presented  as  of  February 9,  2017,  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 9, 2017, 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 9,  2017,  our  drilling  fleet  was  located  in  the  U.K. North Sea (11 units),  U.S. Gulf of Mexico (nine units), 
Trinidad (nine units),  Spain (four units),  Brazil (three units),  Malaysia (three units),  Norway (three units).  Thailand (three units), 
Canada (two units), Congo (two units), India (two units), Angola (one unit), Myanmar (one unit), Romania (one unit), South Africa (one unit) 
and 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 related services reflects oil companies’ demand for equipment for drilling exploration, 
appraisal  and  development  wells  and  for  performing  maintenance  on  existing  production  wells.    Activity  levels  of  exploration  and 
production (“E&P”) companies and their associated capital expenditures are largely driven by the worldwide demand for energy, including 
crude oil and natural gas.  Worldwide energy supply and demand drives oil and natural gas prices, which, in turn, impact E&P companies’ 
ability to fund investments in exploration, development and production activities. 

The industry is presently experiencing a cyclical downturn.  Sustained weak commodity pricing has resulted in our customers 
delaying investment decisions and postponing exploration and production programs.  Although oil and natural gas prices have improved 
recently, such 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  observed  a  sharp  decline  in  the  execution  of  drilling  contracts  for  the  global  offshore  drilling  fleet  and  an 
unprecedented level of drilling contract early terminations and cancellations.  We currently expect few drilling contracts to be awarded in 
2017, 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, 2016, 2015 and 2014, we sold for scrap value 11, 17 and two drilling units, respectively, and at December 31, 2016, we had 
one additional rig 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 
replace reserves to meet global demand for hydrocarbons.  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.  Typically, these projects are technically demanding due to factors such as water depth, complex well 
designs,  deeper  drilling  depth,  high  pressure  and  temperature,  sub-salt,  harsh  environments,  and  heightened  regulatory  standards; 
therefore, they require sophisticated drilling units.  Generally, ultra-deepwater rigs are the most modern, technologically advanced class of 
the  offshore  fleet  and  have  capabilities  that  are  attractive  to  E&P  companies  operating  in  deeper  water  depths,  other  challenging 
environments or with complex well designs.

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,  2016,  the  contract  backlog  was  approximately  $11.7 billion,  representing  a  decrease  of 
27 percent and 48 percent, respectively, compared to the contract backlog at December 31, 2015 and 2014, which was $16.0 billion and 
$22.5 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 may be cancelable for the convenience of the customer upon payment of an early termination 
payment.  Such payments, however, may not fully compensate us for the loss of the contract.  Contracts also customarily provide for either 
automatic  termination  or  termination  at  the  option  of  the  customer,  typically  without  the  payment  of  any  termination  fee,  under  various 
circumstances such as non-performance, in the event of extended downtime or impaired performance caused by equipment or operational 
issues, or periods of extended downtime due to force majeure events.  Many of these events are beyond our control.  The contract term in 
some  instances  may  be  extended  by  the  customer  exercising  options  for  the  drilling  of  additional  wells  or  for  an  additional  term.    Our 
contracts  also  typically  include  a  provision  that  allows  the  customer  to  extend  the  contract  to  finish  drilling  a  well-in-progress.    During 
periods  of  depressed  market  conditions,  our  customers  may  seek  to  renegotiate  firm  drilling  contracts  to  reduce  the  term  of  their 
obligations or the average dayrate through term extensions, or may seek to repudiate their contracts.  Suspension of drilling contracts will 
result in the reduction in or loss of dayrate for the period of the suspension.  If our customers cancel some of our contracts and we are 
unable to secure new contracts on a timely basis and on substantially similar terms, or if contracts are suspended for an extended period 
of time or if a number of our contracts are renegotiated, it could adversely affect our consolidated results of operations or cash flows.  See 
“Item 1A. Risk Factors—Risks related to our business—Our drilling contracts may be terminated due to a number of events, and, during 
depressed market conditions, our customers may seek to repudiate or renegotiate their contracts.” 

Consistent  with  standard  industry  practice,  our  customers  generally  assume,  and  indemnify  us  against,  well  control  and 
subsurface risks under dayrate drilling contracts.  Under all of our current drilling contracts, our customers, as the operators, indemnify us 
for pollution damages in connection with reservoir fluids stemming from operations under the contract and we indemnify the operator for

pollution from substances in our control that originate from the rig, such as diesel used onboard the rig or other fluids stored onboard the 
rig and above the water surface.  Also, under all of our current drilling contracts, the operator indemnifies us against damage to the well or 
reservoir and loss of subsurface oil and gas and the cost of bringing the well under control.  However, our drilling contracts are individually 
negotiated, and the degree of indemnification we receive from the operator against the liabilities discussed above can vary from contract to 
contract, based on market conditions and customer requirements existing when the contract was negotiated.  In some instances, we have 
contractually agreed upon certain limits to our indemnification rights and can be responsible for damages up to a specified maximum dollar 
amount, 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 13—Commitments and Contingencies.” 

Significant Customers 

(together  with 

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,  2016,  our  most  significant 
customers  were  Chevron Corporation 
“BP”), 
Royal Dutch Shell plc (together with its affiliates, “Shell”) and Petróleo Brasileiro S.A. (“Petrobras”), representing approximately 24 percent, 
12 percent,  12 percent  and  11 percent,  respectively,  of  our  consolidated  operating  revenues.    No  other  customers  accounted  for 
10 percent or more of our consolidated operating revenues in the year ended December 31, 2016.  Additionally, as of February 9, 2017, 
the  customers  with  the  most  significant  aggregate  amount  of  contract  backlog  associated  with  our  drilling  contracts  were  Shell  and 
Chevron, representing approximately 63 percent and 20 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

Employees 

We  require  highly  skilled  personnel  to  operate  our  drilling  units.    Consequently,  we  conduct  extensive  personnel  recruiting, 
training  and  safety  programs.    At  December 31,  2016,  we  had  approximately  5,400 employees,  including  approximately  400 persons 
engaged through contract labor providers.  Approximately 28 percent of our total workforce, working primarily in Angola, Brazil, Norway 
and the U.K. 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. 

Joint Venture, Agency and Sponsorship Relationships and Other Investments 

In some areas of the world, local customs and practice or governmental requirements necessitate the formation of joint ventures 
with  local  participation.    We  may  or  may  not  control  these  joint  ventures.    We  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.  At December 31, 2016, joint ventures in which we participate were as follows: 

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

We hold a 24 percent direct interest and a 36 percent indirect interest in Indigo Drilling Limited (“Indigo”), a consolidated Nigerian 
joint  venture  company  formed  to  engage  in  drilling  operations  offshore  Nigeria.    Our  local  partners,  Mr. Fidelis Oditah  and 

AR-8 

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, Nigeria and other countries that 

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

Technological Innovation 

Since  launching  the  offshore  industry’s  first jackup  drilling  rig  in  1954,  we  have  achieved  a  long  history  of  technological 
innovations, including the first dynamically positioned drillship, the first rig to drill year-round in the North Sea and the first semisubmersible 
rig  for  year-round  sub-Arctic  operations.    We  have  repeatedly  achieved  water  depth  world  records  in  the  past.    Twenty drillships  and 
semisubmersibles  in  our  existing  fleet  are,  and  our  four drillships  that  are  under  construction  will  be,  equipped  with  our  patented 
dual-activity  technology,  which  allows  our  rigs  to  perform  simultaneous  drilling  tasks  in  a  parallel  rather  than  sequential  manner  and 
reduces critical path activity while improving efficiency in both exploration and development drilling.  Additionally, three rigs in our existing 
fleet are equipped with the 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  include  industry-leading  hookload  capability,  compensated  cranes  for  performing  subsea 
installations, hybrid power systems and reduced emissions and advanced generator protection.  Seven drillships in our existing fleet are, 
and  our  four drillships  that  are  under  construction  will  be,  outfitted  with  two blowout  preventers  and  triple  liquid  mud  systems.  
Three drillships in our existing fleet are, and our four drillships that are under construction will be, 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 continue to develop technology internally, 
such as the digital transformation program focused on utilizing analytics and data science to continuously improve operational integrity and 
efficiency while optimizing cost.  In addition, we are focused on a breakthrough drilling innovation program that includes a fault-resistant 
and fault-tolerant blowout preventer control system. 

Environmental Compliance 

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

Risk Factors 

Risks related to our business 
(cid:131)  Our business depends on the level of activity in the offshore oil and gas industry, which is significantly affected by volatile 

oil and gas prices and other factors. 

Our  business  depends  on  the  level  of  activity  in  oil  and  gas  exploration,  development  and  production  in  offshore  areas 
worldwide.  Demand for our services depends on oil and natural gas industry activity and expenditure levels that are directly affected by 
trends in oil and, to a lesser extent, natural gas prices.  Oil and gas prices are extremely volatile and are affected by numerous factors, 
including the following: 
(cid:131) 
(cid:131) 

worldwide demand for oil and gas, including economic activity in the U.S. and other large energy-consuming markets; 
the  ability  of  the  Organization  of  the  Petroleum  Exporting  Countries  (“OPEC”)  to  set  and  maintain  production  levels,  productive  spare 
capacity and pricing; 
the level of production in non-OPEC countries; 
the policies of various governments regarding exploration and development of their oil and gas reserves; 
international sanctions on oil-producing countries, or the lifting of such sanctions; 
advances in exploration, development and production technology; 
the further development of shale technology to exploit oil and gas reserves; 
the discovery rate of new oil and gas reserves; 
the rate of decline of existing oil and gas reserves; 
laws  and  regulations  related  to  environmental  matters,  including  those  addressing  alternative  energy  sources  and  the  risks  of  global 
climate change; 
the development and exploitation of alternative fuels; 
accidents, adverse weather conditions, natural disasters and other similar incidents relating to the oil and gas industry; and 
the  worldwide  security  and  political  environment,  including  uncertainty  or  instability  resulting  from  an  escalation  or  outbreak  of  armed 
hostilities, civil unrest or other crises in the Middle East or other geographic areas or acts of terrorism.

Demand  for  our  services  is  particularly  sensitive  to  the  level  of  exploration,  development  and  production  activity  of,  and  the 
corresponding capital spending by, oil and natural gas companies, including national oil companies.  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 offshore 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 continue.  The price of 
crude oil as reported on the New York Mercantile Exchange has weakened significantly and, despite recent price improvements, has not 
returned  to  the  higher  levels  experienced  prior  to  December 31,  2014.    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  a 
qualified contractor is awarded a job. 

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

AR-10 

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 
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  four 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 oversupplied market, we may have limited bargaining power to negotiate on 
more favorable terms.  Lower dayrates and rig utilization rates could adversely affect our revenues and profitability. 

(cid:131)  Our  drilling  contracts  may  be  terminated  due  to  a  number  of  events,  and,  during  depressed  market  conditions,  our 

customers may seek to repudiate or renegotiate their contracts. 

Certain  of  our  drilling  contracts  with  customers  may  be  cancelable  at  the  option  of  the  customer  upon  payment  of  an  early 
termination  payment.    Such  payments  may  not,  however,  fully  compensate  us  for  the  loss  of  the  contract.    Drilling  contracts  also 
customarily  provide  for  either  automatic  termination  or  termination  at  the  option  of  the  customer  typically  without  the  payment  of  any 
termination  fee,  under  various  circumstances  such  as  non-performance,  as  a  result  of  significant  downtime  or  impaired  performance 
caused by equipment or operational issues, or  sustained periods  of downtime due to force majeure events.  Many of these events  are 
beyond  our  control.    During  periods  of  depressed  market  conditions,  we  are  subject  to  an  increased  risk  of  our  customers  seeking  to 
repudiate  their  contracts,  including  through  claims  of  non-performance.    We  are  at  continued  risk  of  experiencing  early  contract 
terminations in the current weak commodity price environment as operators look to reduce their capital expenditures.  During the years 
ended December 31, 2016 and 2015, our customers early terminated or cancelled contracts for eight and five of our rigs, respectively, and 
these rigs currently remain idle.  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 9, 2017, our contract backlog was approximately $11.3 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, and, during depressed market conditions, our 
customers may seek to repudiate or renegotiate their contracts.”)  Our inability to realize the full amount of our contract backlog may have 
a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

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

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, 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 consolidated statements of financial condition, results of operations and cash flows.

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. 

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.    During  the  year  ended 
December 31,  2016  and  in  January 2017,  the  same  three credit  rating  agencies  further  downgraded  our  Debt Rating.    Our  Debt Rating 
levels could have material adverse consequences on our business and future prospects and could:

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, including secured debt, and we may lose the ability to obtain future financing and 

suffer competitive disadvantages. 

At December 31, 2016 and 2015, our total consolidated debt was $8.5 billion.  This substantial level of debt and other obligations 

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

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

(cid:131) 

we  may  be  unable  to  obtain  financing  in  the  future  for  working  capital,  capital  expenditures,  acquisitions,  debt  service  requirements, 
distributions, share repurchases, or other purposes; 
we may be unable to use operating cash flow in other areas of our business because we must dedicate a substantial portion of these 
funds to service the debt; 
we could become more vulnerable to general adverse economic and industry conditions, including increases in interest rates, particularly 
given our substantial indebtedness, some of which bears interest at variable rates; 
we  may  be  unable  to  meet  financial  ratios  in  the  indentures  governing  certain  of  our  debt  or  in  our  bank  credit  agreements  or  satisfy 
certain other conditions included in our bank credit agreements, which could result in our inability to meet requirements for borrowings 
under our credit agreements or a default under these indentures or agreements, impose restrictions with respect to our access to certain 
of our capital, and trigger cross default provisions in our other debt instruments; 
if we default under the terms of our secured financing arrangements, the secured debtholders may, among other things, foreclose on the 
collateral securing the debt, including the applicable drilling units; and 
we may be less able to take advantage of significant business opportunities and to react to changes in market or industry conditions than 
our less levered competitors. 

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

Resources—Sources and Uses of Liquidity—Debt Issuances.” 

(cid:131)  We rely heavily on a relatively small number of customers and the loss of a significant customer or a dispute that leads to 
the loss of a customer could have a material adverse impact on our consolidated statement of financial position, results of 
operations or cash flows. 

We engage in offshore drilling services for most of the leading international oil companies or their affiliates, as well as for many 
government-controlled  oil  companies  and  independent  oil  companies.    For  the  year  ended  December 31,  2016,  our  most  significant 
customers  were  Chevron,  BP,  Shell  and  Petrobras,  accounting  for  approximately  24 percent,  12 percent,  12 percent  and  11 percent, 
respectively, of our consolidated operating revenues.  As of February 9, 2017, the customers with the most significant aggregate amount of 
contract  backlog  were  Shell  and  Chevron,  representing  approximately  63 percent  and  20 percent,  respectively,  of  our  total  contract 
backlog.  The loss of any of these customers or another significant customer, or a decline in payments under any of our drilling contracts, 
could, at least in the short term, have a material adverse effect on our results of operations and cash flows. 

In  addition,  our  drilling  contracts  subject  us  to  counterparty  risks.    The  ability  of  each  of  our  counterparties  to  perform  its 
obligations under a contract with us will depend on a number of factors that are beyond our control and may include, among other things, 
general economic conditions, the condition of the offshore drilling industry, prevailing prices for oil and natural gas, the overall financial 
condition  of  the  counterparty,  the  dayrates  received  and  the  level  of  expenses  necessary  to  maintain  drilling  activities.    In  addition,  in 
depressed market conditions, such as we are currently experiencing, our customers may no longer need a drilling rig that is currently under 
contract or may be able to obtain a comparable drilling rig at a lower dayrate.  Should a counterparty fail to honor its obligations under an 
agreement  with  us,  we  could  sustain  losses,  which  could  have  a  material  adverse  effect  on  our  business  and  on  our  consolidated 
statement of financial condition results of operations or cash flows. 

AR-13 

(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. 

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

(cid:131)  Our operating and maintenance costs will not necessarily fluctuate in proportion to changes in our operating revenues. 

Our operating and maintenance costs will not necessarily fluctuate in proportion to changes in our operating revenues.  Costs for 
operating  a  rig  are  generally  fixed  or  only  semi-variable  regardless  of  the  dayrate  being  earned.    In  addition,  should  our  rigs  incur 
unplanned downtime while on contract or idle time between drilling contracts, we will not always reduce the staff on those rigs because we 
could use the crew to prepare the rig for its next contract.  During times of reduced activity, reductions in costs may not be  immediate 
because portions of the crew may be required to prepare rigs for stacking, after which time the crew members may be assigned to active 
rigs or released.  As our rigs are mobilized from one geographic location to another, the labor and other operating and maintenance costs 
can vary significantly.  In general, labor costs increase primarily due to higher salary levels and inflation.  Equipment maintenance costs 
fluctuate depending upon the type of activity the unit is performing and the age and condition of the equipment, and these costs could 
increase  for  short  or  extended  periods  as  a  result  of  regulatory  or  customer  requirements  that  raise  maintenance  standards  above 
historical levels.  Contract preparation costs vary based on the scope and length of contract preparation required and the duration of the 
firm contractual period over which such expenditures are amortized. 

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

As of February 9, 2017, we had four ultra-deepwater floater and five high-specification jackup newbuild rigs under construction.  
We also have a variety of other more limited shipyard projects at any given time.  These shipyard projects are subject to the risks of delay 
or cost overruns inherent in any such construction project resulting from numerous factors, including the following:

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 impact contract commencement, resulting in a loss of revenue to us, and 
may also cause customers to terminate or shorten the term of the drilling contract for the rig pursuant to applicable late delivery clauses.  In 
the event of termination of any of these drilling contracts, we may not be able to secure a replacement contract on as favorable terms, if at 
all. 

Our operations also rely on a significant supply of capital and consumable spare parts and equipment to maintain and repair our 
fleet.    We  also  rely  on  the  supply  of  ancillary  services,  including  supply  boats  and  helicopters.    Shortages  in  materials,  manufacturing 

AR-14 

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 13—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 
with our settlement with the Department of Justice (the “DOJ”), we agreed that we will not use payments pursuant to a civil consent decree 
by and among the DOJ and certain of our affiliates (the “Consent Decree”) as a basis for indemnity or reimbursement from non-insurer 
defendants named in the complaint by the U.S. or their affiliates. 

(cid:131)  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. 

(cid:131) 

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

Following  the  Macondo  well  incident,  enhanced  governmental  safety  and  environmental  requirements  applicable  to  both 
deepwater and shallow water operations were adopted for drilling in the U.S. Gulf of Mexico.  In order to obtain drilling permits, operators 
must submit applications that demonstrate compliance with the enhanced regulations, which require independent third-party inspections, 
certification  of  well  design  and  well  control  equipment  and  emergency  response  plans  in  the  event  of  a  blowout,  among  other 
requirements.  Operators have previously had, and may in the future have, difficulties obtaining drilling permits in the U.S. Gulf of Mexico.  
In  addition,  the  oil  and  gas  industry  has  adopted  new  equipment  and  operating  standards,  such  as  the  American  Petroleum  Institute 
Standard 53  related  to  the  installation  and  testing  of  well  control  equipment.    These  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. 

(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 

AR-15 

drilling industry depends on demand for services from the oil and gas exploration and production industry, and, accordingly, we are directly 
affected  by  the  adoption  of  laws  and  regulations  that,  for  economic,  environmental  or  other  policy  reasons,  curtail  exploration  and 
development drilling for oil and gas.  Compliance with such laws, regulations and standards, where applicable, may require us to make 
significant capital expenditures, such as the installation of costly equipment or operational changes, and may affect the resale values or 
useful  lives  of  our  rigs.    We  may  also  incur  additional  costs  in  order  to  comply  with  other  existing  and  future  regulatory  obligations, 
including, but not limited to, costs relating to air emissions, including greenhouse gases, the management of ballast waters, maintenance 
and inspection, development and implementation of emergency procedures and insurance coverage or other financial assurance of our 
ability  to  address  pollution  incidents.    Offshore  drilling  in  certain  areas  has  been  curtailed  and,  in  certain  cases,  prohibited  because  of 
concerns over protection of the environment.  These costs could have a material adverse effect on our consolidated statement of financial 
position, results of operations or cash flows.  A failure to comply with applicable laws and regulations may result in administrative and civil 
penalties, criminal sanctions or the suspension or termination of our operations. 

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

AR-16 

personnel.  We are also subject to the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) and other U.S. laws and 
regulations governing our international operations.  In addition, various state and municipal governments, universities and other investors 
have proposed or adopted divestment and other initiatives regarding investments including, with respect to state governments, by state 
retirement systems in companies that do business with countries that have been designated as state sponsors of terrorism by the U.S. 
State Department.  Failure to comply with applicable laws and  regulations, including those relating to sanctions and export restrictions, 
may  subject  us  to  criminal  sanctions  or  civil  remedies,  including  fines,  denial  of  export  privileges,  injunctions  or  seizures  of  assets.  
Investors could view any potential violations of OFAC regulations negatively, which could adversely affect our reputation and the market for 
our shares. 

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

A  substantial  portion  of  our  drilling  contracts  are  partially  payable  in  local  currency.    Those  amounts  may  exceed  our  local 
currency  needs,  leading  to  the  accumulation  of  excess  local  currency,  which,  in  certain  instances,  may  be  subject  to  either  temporary 
blocking  or  other  difficulties  converting  to  U.S.  dollars,  our  functional  currency,  or  to  other  currencies  in  which  we  operate.    Excess 
amounts of local currency may be exposed to the risk of currency exchange losses. 

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

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

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

(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 

AR-17 

personnel shortages.  We customarily provide contract indemnity to our customers for certain claims that could be asserted by us relating 
to damage to or loss of our equipment, including rigs, and claims that could be asserted by us or our employees relating to personal injury 
or loss of life. 

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

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

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

(cid:131)  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 each of our 2015 and 2016 annual 
general meetings our shareholders approved in a binding “say on pay” vote the compensation of members of our executive management 
and  board  of  directors.    At  the  2017 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 2017 annual general meeting and the 2018 annual general meeting 
and (2) our executive management team for the year ending December 31, 2018.  Our shareholders will be asked to approve such matters 
for successive one-year periods at subsequent annual general meetings.  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 
acquisitions, divestitures and other business combinations in order to optimize our fleet and strengthen our competitiveness.  We face risks 
arising from these activities, which could adversely affect our ability to achieve our strategic goals.  For example: 

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

these activities in the expected time period or at all; 
Transactions may not be completed as scheduled or at all due to legal or regulatory requirements, market conditions or contractual and 
other conditions to which such transactions are subject; 
Unanticipated  problems  could  also  arise  in  the  integration  or  separation  processes,  including  unanticipated  restructuring  or  separation 
expenses  and  liabilities,  as  well  as  delays  or  other  difficulties  in  transitioning,  coordinating,  consolidating,  replacing  and  integrating 
personnel, information and management systems, and customer products and services; 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) 

Failure to recruit and retain key personnel could hurt our operations. 

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

(cid:131)  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 28 percent of our total workforce, working primarily in Angola, Brazil, Norway and the U.K. 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 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,  including  greenhouse  gases,  carbon  dioxide  and 
methane, may be contributing to warming of the earth’s atmosphere and other climatic changes.  In response to such studies, the issue of 
climate  change  and  the  effect  of  greenhouse  gas  emissions,  in  particular  emissions  from  fossil  fuels,  is  attracting  increasing  attention 
worldwide. 

AR-19 

In  the  U.S.,  the  EPA  has  begun  adopting  and  implementing  a  comprehensive  suite  of  regulations  to  restrict  emissions  of 
greenhouse gases under existing provisions of the Clean Air Act.  In addition, a number of other federal, state and regional efforts have 
focused on tracking or reducing greenhouse gas emissions.  Efforts have also been made and continue to be made in the international 
community toward the adoption of international treaties or protocols that would address global climate change issues.  In December 2015, 
the U.S. joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate 
Change in Paris, France.  The resulting Paris Agreement calls for the parties to undertake “ambitious efforts” to limit the average global 
temperature  and  to  conserve  and  enhance  sinks  and  reservoirs  of  greenhouse  gases.    The  Paris  Agreement,  if  ratified,  establishes  a 
framework for the parties to cooperate and report actions to reduce greenhouse gas emissions. 

Because our business depends on the level of activity in the offshore oil and gas industry, existing or future laws, regulations, 
treaties  or  international  agreements  related  to  greenhouse  gases  and  climate  change,  including  incentives  to  conserve  energy  or  use 
alternative energy sources, could have a negative impact on our business if such laws, regulations, treaties or international agreements 
reduce  the  worldwide  demand  for  oil  and  gas  or  limit  drilling  opportunities.    In  addition,  such  laws,  regulations,  treaties  or  international 
agreements  could  result  in  increased  compliance  costs  or  additional  operating  restrictions,  which  may  have  a  negative  impact  on  our 
business. 

(cid:131)  We  are  subject  to  litigation  that,  if  not  resolved  in  our  favor  and  not  sufficiently  insured  against,  could  have  a  material 

adverse effect on us. 

We  are  subject  to  a  variety  of  disputes,  investigations  and  litigation.    Certain  of  our  subsidiaries  are  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 subject to litigation with certain of our customers.  We are also subject to a number of significant tax disputes.  
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 

AR-20 

of demand for our services.  Quarantine of personnel or inability to access our offices or rigs could adversely affect our operations.  Travel 
restrictions  or  operational  problems  in  any  part  of  the  world  in  which  we  operate,  or  any  reduction  in  the  demand  for  drilling  services 
caused by public health threats in the future, may materially impact operations and adversely affect our financial results. 

Other risks 

(cid:131)  We recently identified a material weakness in our internal control over financial reporting, and our business and stock price 

may be adversely affected if our internal control over financial reporting is not effective. 

Under  Section 404  of  the  Sarbanes-Oxley  Act  of  2002  and  rules  promulgated  by  the  SEC,  we  are  required  to  conduct  a 
comprehensive evaluation of our internal control over financial reporting.  To complete this evaluation, we are required to document and 
test our internal control over financial reporting; management is required to assess and issue a report concerning our internal control over 
financial reporting; and our independent registered public accounting firm is required to attest to the effectiveness of our internal control 
over  financial  reporting.    Our  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements  because  of  its  inherent 
limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud.  Over time, controls may become 
inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.  Because of the 
inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be prevented or detected 
timely.  Even effective internal control over financial reporting can provide only reasonable assurance with respect to the preparation and 
fair presentation of financial statements. 

In the course of the external audit of the consolidated financial statements for the year ended December 31, 2016 we identified a 
material weakness in our controls over income tax accounting.  A material weakness is a deficiency, or a combination of deficiencies, in 
internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim 
financial statements will not be prevented or detected on a timely basis.  A more complete description of the recently identified errors and 
the  resulting  material  weakness  is  included  in  “Part II.  Item 8.  Financial  Statements  and  Supplementary  Data—Notes  to  Consolidated 
Financial  Statements—Note 4—Correction  of  Errors  in  previously  Reported  Consolidated  Financial  Statements”  and  “Part II.  Item 9A. 
Controls  and  Procedures”  in  this  annual  report.    Although  we  are  evaluating  certain  measures  in  order  to  remediate  this  material 
weakness, we can provide no assurance that our remediation efforts will be effective or that additional material weaknesses in our internal 
control over financial reporting will not be identified in the future. 

The  existence  of  a  material  weakness  could  result  in  errors  in  our  financial  statements  that  could  result  in  a  restatement  of 
financial  statements,  which  could  cause  us  to  fail  to  meet  our  reporting  obligations,  lead  to  a  loss  of  investor  confidence  and  have  a 
negative impact on the trading price of our common stock. 

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

At December 31, 2016, the carrying amount of our property and equipment was $21.1 billion, representing 78 percent of our total 
assets.  In accordance with our critical accounting policies, we review our property and equipment for impairment when events or changes 
in circumstances indicate that carrying amounts of our assets held and used may not be recoverable.  In the year ended December 31, 
2016, we recognized an aggregate loss of $52 million associated with the impairment of our deepwater floater asset group.  In the year 
ended December 31, 2015, we recognized an aggregate loss of $1.2 billion associated with the impairment of our deepwater floater and 
midwater floater asset groups.  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., major tax reform is under consideration.  One proposal by the U.S. House of Representatives would impose a border 
adjustment on goods and services imported into the U.S.  Although no bill or statutory language has to date been introduced, it is expected 
that such border adjustment would have the direct or indirect effect of taxing goods and services sourced from outside the U.S.  Such a 
border adjustment, if implemented, could result in a higher effective tax rate on our worldwide earnings and have a material adverse effect 
on  our  consolidated  statements  of  financial  position,  results  of  operations  or  cash  flows.    Further,  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, 

AR-21 

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.  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 a referendum held on February 12, 2017, Swiss voters rejected a corporate tax legislative proposal that would have abolished 
certain cantonal tax privileges as well as implement other significant changes to existing tax laws and practices starting in 2019.  These 
legislative proposals were in response to certain guidance from and demands by the European Union and the Organization for Economic 
Co-operation  and  Development  (the  “OECD”).    Switzerland  must  now  give  consideration  to  a  revised  corporate  tax  reform  proposal.  
Switzerland’s implementation of any material change in tax laws or policies or its adoption of new interpretations of existing tax laws and 
rulings could result in a higher effective tax rate on our worldwide earnings and such change could have a material adverse effect on our 
consolidated statement of financial position, results of operations or cash flows. 

Similarly, in October 2015, the OECD issued its action plan of tax reform measures that called for member states to take action 
to  prevent  “base  erosion  and  profit  shifting”.    Some  of  these  measures  impact  transfer  pricing,  requirements  to  qualify  for  tax  treaty 
benefits, and the definition of permanent establishments depending on each jurisdiction’s adoption and interpretation of such proposals.    
The European Union issued its Anti-Tax Avoidance Directive in 2016 that required its member states to adopt specific tax reform measures 
by 2019.  Any material change in tax laws or policies, or their interpretation, resulting from such legislative proposals or inquiries could 
result in a higher effective tax rate on our worldwide earnings and such change could have a material adverse effect on our consolidated 
statement of financial position, results of operations or cash flows. 

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

(cid:131)  A loss of a major tax dispute or a successful tax challenge to our operating structure, intercompany pricing policies or the 
taxable presence of our key subsidiaries in certain countries could result in a higher tax rate on our worldwide earnings, 
which could result in a significant negative impact on our earnings and cash flows from operations. 

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

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,  India  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 

AR-22 

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 generally would be liable to pay U.S. 
federal income tax at the highest applicable income tax rates on ordinary income upon the receipt of excess distributions, as defined for 
U.S. tax purposes, and upon any gain from the disposition of our shares, plus interest on such amounts, as if such excess distribution or 
gain had been recognized ratably over the shareholder’s holding period of our shares.  In addition, under applicable statutory provisions, 
the preferential tax rate on “qualified dividend income,” which applies to dividends paid to non-corporate shareholders does not apply to 
dividends  paid  by  a  foreign  corporation  if  the  foreign  corporation  is  a  PFIC  for  the  taxable  year  in  which  the  dividend  is  paid  or  the 
preceding taxable year. 

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

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

(cid:131)  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  2016 annual  general 
meeting, our shareholders approved an authorized share capital, which will expire on May 12, 2018.  Our current authorized share capital 
is  limited  to  approximately  six percent  of  our  registered  share  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.  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 

AR-23 

require  the  approval  of  the  competent  Swiss  tax  authorities.    We  may  not  be  able  to  repurchase  as  many  shares  as  we  would  like  to 
repurchase  for  purposes  of  capital  reduction  on  the  “virtual  second trading  line”  without  subjecting  the  selling  shareholders  to  Swiss 
withholding taxes. 

(cid:131)  As a Swiss corporation, we are subject to Swiss legal provisions that may limit our flexibility to swiftly implement certain 

initiatives or strategies. 

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

(cid:131)  We are subject to anti-takeover provisions. 

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

provide  that  the  board  of  directors  is  authorized,  subject  to  obtaining  shareholder  approval  every  two years,  at  any  time  during  a 
maximum  two-year  period,  which  under  the  current  authorized  share  capital  of  the  Company  will  expire  on  May 12,  2018,  to  issue  a 
specified number of shares, which under the current authorized share capital of the Company is approximately 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  approximately 
36  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. 

(cid:131) 

The results of the U.K.’s referendum on withdrawal from the European Union may have a negative effect on global economic 
conditions, financial markets and our business. 

In  June 2016,  a  majority  of  voters  in  the  U.K.  elected  to  withdraw  from  the  European  Union  in  a  national  referendum.    The 
referendum was advisory, and the terms of any withdrawal are subject to a negotiation period that could last at least two years after the 
government of the U.K. formally initiates a withdrawal process.  Nevertheless, the referendum has created significant uncertainty about the 
future relationship between the U.K. and the European Union, including with respect to the laws and regulations that will apply as the U.K. 
determines which European Union-derived laws to replace or replicate in the event of a withdrawal.  The referendum has also given rise to 
calls for the governments of other European Union member states to consider withdrawal.  These developments, or the perception that any 
of them could occur, have had and may continue to have a material adverse effect on global economic conditions and the stability of global 
financial markets, and may significantly reduce global market liquidity and restrict the ability of key market participants to operate in certain 
financial markets.  Any of these factors could depress economic activity and restrict our access to capital, which could have a material 
adverse effect on our business and on our consolidated statement of financial position, results of operations or cash flows.

Legal Proceedings 

We have certain actions, claims and other matters pending as discussed and reported in “Part II. Item 8. Financial Statements 
and Supplementary Data—Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies” and “Part II. Item 7. 
Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations—Contingencies  and  Uncertainties—”  in  this 
annual report for the year ended December 31, 2016.  We are also involved in various tax matters as described in “Part II. Item 8. Financial 
Statements  and  Supplementary  Data—Notes  to  Consolidated  Financial  Statements—Note 7—Income  Taxes”  and  in  “Part II.  Item 7. 
Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contingencies and Uncertainties—Tax matters” 
in this annual report for the year ended December 31, 2016.  All such actions, claims, tax and other matters are incorporated herein by 
reference. 

As of December 31, 2016, we were also involved in a number of other lawsuits, claims and disputes, which have arisen in the 
ordinary  course  of  our  business  and  for  which  we  do  not  expect  the  liability,  if  any,  to  have  a  material  adverse  effect  on  our  current 
consolidated statement of financial position, results of operations or cash flows.  We cannot predict with certainty the outcome or effect of 
any of the matters referred to above or of any such other pending or threatened litigation or legal proceedings.  There can be no assurance 
that our beliefs or expectations as to the outcome or effect of any lawsuit or claim or dispute will prove correct and the eventual outcome of 
these matters could materially differ from management’s current estimates. 

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

Our shares were previously listed on the SIX Swiss Exchange (“SIX”) under the symbol “RIGN”.  Effective March 31, 2016, at our 

request, our shares were delisted from the SIX. 

On February 28, 2017, the last reported sales price of our shares on the NYSE was $13.82 per share.  On February 28, 2017, 

there were 6,278 holders of record of our shares and 389,597,755 shares outstanding. 

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

In May 2014, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in 
the  form  of  a  U.S.  dollar  denominated  dividend  of  $3.00 per  outstanding  share,  payable  in  four quarterly  installments  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. 

We did 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 

AR-28 

 
 
 
 
 
 
 
 
 
 
 
 
    
    
     
    
    
such non-Swiss holder.  In such case, the non-Swiss holder is required to recognize capital gains or losses on the sale of such shares, 
which will be subject to cantonal, communal and federal income tax. 

Swiss  withholding  tax  on  dividends  and  similar  distributions  to  shareholders—A  Swiss  withholding  tax  of  35 percent  is 
due on dividends and similar distributions to our shareholders from us, regardless of the place of residency of the shareholder, subject to 
the exceptions discussed under “—Exemption” below.  We will be required to withhold at such rate and remit on a net basis any payments 
made to a holder of our shares and pay such withheld amounts to the Swiss federal tax authorities. 

Exemption—Distributions to shareholders in the form of a par value reduction or out of qualifying additional paid-in capital for 
Swiss  statutory  purposes  are  exempt  from  Swiss  withholding  tax.    On  December 31,  2016,  the  aggregate  amount  of  par  value  of  our 
outstanding shares was CHF 39 million, equivalent to approximately $39 million, and the aggregate amount of qualifying additional paid-in 
capital  of  our  outstanding  shares  was  CHF 11.4 billion,  equivalent  to  approximately  $11.2 billion.    Consequently,  we  expect  that  a 
substantial amount of any potential future distributions may be exempt from Swiss withholding tax. 

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

Refund available to non-Swiss holders—If the shareholder that receives a distribution from us is not a Swiss tax resident, does 
not hold our shares in connection with a permanent establishment or a fixed place of business maintained in Switzerland, and resides in a 
country that has concluded a treaty for the avoidance of double taxation with Switzerland for which the conditions for the application and 
protection of and by the treaty are met, then the shareholder may be entitled to a full or partial refund of the withholding tax described 
above.  Switzerland has entered into bilateral treaties for the avoidance of double taxation with respect to income taxes with numerous 
countries, including the U.S., whereby under certain circumstances all or part of the withholding tax may be refunded.  The procedures for 
claiming treaty refunds, and the time frame required for obtaining a refund, may differ from country to country. 

Refund available to U.S. residents—The Swiss-U.S. tax treaty provides that U.S. residents eligible for benefits under the treaty 
can seek a refund of the Swiss withholding tax on dividends for the portion exceeding 15 percent, leading to a refund of 20 percent, or a 
100 percent refund in the case of qualified pension funds.  As a general rule, the refund will be granted under the treaty if the U.S. resident 
can show evidence of the following: (a) beneficial ownership, (b) U.S. residency and (c) meeting the U.S.-Swiss tax treaty’s limitation on 
benefits requirements. 

The claim for refund must be filed with the Swiss federal tax authorities (Eigerstrasse 65, 3003 Bern, Switzerland), not later than 
December 31 of the third year following the year in which the dividend payments became due.  The relevant Swiss tax form is Form 82C 
for companies, 82E for other entities and 82I for individuals.  These forms can be obtained from any Swiss Consulate General in the U.S. 
or  from  the  Swiss  federal  tax  authorities  at  the  above  address  or  can  be  downloaded  from  the  webpage  of  the  Swiss  federal  tax 
administration.  Each form must be completed in triplicate, with each copy duly completed and signed before a notary public in the U.S.  
Evidence that the withholding tax was withheld at the source must also be included. 

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

Share repurchases 

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

If we repurchase shares, we expect to use an alternative procedure pursuant to which we repurchase our shares via a "virtual 
second trading line" from market players, such as banks and institutional investors, who are generally entitled to receive a full refund of the 
Swiss withholding tax.  Currently, our ability to use the “virtual second trading line” will be limited to the share repurchase program currently 
approved  by  our  shareholders,  and  any  use  of  the  “virtual  second trading  line”  with  respect  to  future  share  repurchase  programs  will 
require approval of the competent Swiss tax and other authorities.  We may not be able to repurchase as many shares as we would like to 

AR-29 

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. 

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 28, 2017, Transocean Inc., our wholly owned subsidiary, held as treasury 
shares  approximately  one percent  of  our  issued  shares.    Our  board  of  directors  could,  to  the  extent  freely  distributable  reserves  are 
available, authorize the repurchase of additional shares for purposes other than cancellation, such as to retain treasury shares for use in 
satisfying our obligations in connection with incentive plans or other rights to acquire our shares.  Based on the current amount of shares 
held  as  treasury  shares,  approximately  nine percent  of  our  issued  shares  could  be  repurchased  for  purposes  of  retention  as  additional 
treasury  shares.    Although  our  board  of  directors  has  not  approved  such  a  share  repurchase  program  for  the  purpose  of  retaining 
repurchased shares as treasury shares, if it did so, any such shares repurchased would be in addition to any shares repurchased under 
the currently approved program.

(a)  Total number of shares purchased in the fourth quarter of 2016 consists of 9,917 shares withheld by us through a broker arrangement and limited to 
statutory  tax  in  satisfaction  of  withholding  taxes  due  upon  the  vesting  of  restricted  share  units  granted  to  our  employees  under  our  long-term 
incentive plan. 
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  $3.4 billion.    On 
February 12, 2010, our board of directors authorized our management to implement the share repurchase program.  Through December 31, 2016, 
we repurchased a total of 2,863,267 of our shares under our share repurchase program at a total cost of $240 million, equivalent to an average cost 
of $83.74 per share.  On October 29, 2015, at our extraordinary general meeting, shareholders approved the cancellation of all shares that were 
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.    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.    See  “Item 7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations—Liquidity  and  Capital 
Resources—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 28,  2017,  we  owned  or  had  partial  ownership  interests  in  and  operated  56 mobile  offshore  drilling  units,  including 
30 ultra-deepwater  floaters,  seven harsh  environment  floaters,  three deepwater  floaters,  six midwater  floaters,  and  10 high-specification 
jackups.  At February 16, 2017, we also had four 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. 

Significant Events 

Transocean Partners—On  December 9,  2016,  Transocean Partners  completed  a  merger  with  one of  our  subsidiaries  as 
contemplated under the Agreement and Plan of Merger (the “Merger Agreement”), dated July 31, 2016 and as amended on November 21, 
2016.  Following the completion of the merger, Transocean Partners became a wholly owned indirect subsidiary of Transocean Ltd.  Each 
Transocean Partners  common  unit  that  was  issued  and  outstanding  immediately  prior  to  the  closing,  other  than  the  units  held  by 
Transocean  and  its  subsidiaries,  was  converted  into  the  right  to  receive  1.20 of  our  shares.    To  complete  the  merger,  we  issued 
23.8 million shares from conditional capital. 

Debt issuances—On July 21, 2016, we completed an offering of an aggregate principal amount of $1.25 billion of 9.00% senior 
unsecured notes due July 15, 2023 (the “9.00% Senior Notes”), and we received aggregate cash proceeds of $1.21 billion, net of initial  
discount and costs payable by us.  On October 19, 2016, we completed an offering of an aggregate principal amount of $600 million of 
7.75% senior  secured  notes  due  October 15,  2024  (the  “7.75% Senior  Secured  Notes”),  and  we  received  aggregate  cash  proceeds  of 
$583 million, net of initial discount and costs payable by us.  On December 8, 2016, we completed an offering of an aggregate principal 
amount  of  $625 million  of  6.25% senior  secured  notes  due  December 1,  2024  (the  “6.25% Senior  Secured  Notes”),  and  we  received 
aggregate  cash  proceeds  of  $609 million,  net  of  initial  discount  and  costs  payable  by  us.    See  “—Liquidity  and  Capital  Resources—
Sources and uses of liquidity.” 

Debt tender offer—On August 1, 2016, we completed a tender offer (the “Tender Offer”) to purchase for cash up to $1.0 billion 
aggregate principal amount of certain of our outstanding senior notes (collectively, the “Tendered Notes”).  In connection with the Tender 
Offer, we received valid tenders from holders of an aggregate principal amount of $981 million of the Tendered Notes, and we made an 
aggregate cash payment of $876 million to settle the Tendered Notes.  In the year ended December 31, 2016, as a result of the retirement 
of  the  Tendered  Notes,  we  recognized  an  aggregate  gain  of  $104 million  associated  with  the  retirement  of  debt.    See  “—Liquidity  and 
Capital Resources—Sources and uses of liquidity.” 

Debt repurchases—During the year ended December 31, 2016, we completed transactions to repurchase in the open market 
an  aggregate  principal  amount  of  $399 million  of  our  debt  securities  for  an  aggregate  cash  payment  of  $354 million.    As  a  result,  we 
recognized an aggregate gain of $44 million associated with the retirement of debt.  See “—Liquidity and Capital Resources—Sources and 
uses of liquidity”. 

Fleet  expansion—During  the  year  ended  December 31,  2016,  we  completed  construction  of  and  placed  into  service  the 
ultra-deepwater floaters Deepwater Thalassa, Deepwater Proteus and Deepwater Conqueror.  See “—Operating Results” and “—Liquidity 
and Capital Resources—Drilling fleet.” 

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,  2016,  we  recognized  revenues  of 

AR-32 

$471 million and received aggregate cash proceeds of $453 million associated with early terminated or cancelled drilling contracts.  See 
“—Outlook,” “—Operating Results” and “—Liquidity and Capital Resources—Sources and uses of cash.” 

Dispositions—During the year ended December 31, 2016, we completed the sale for scrap value of three deepwater floaters 
and  eight midwater  floaters,  along  with  related  equipment,  for  which  we  received  net  cash  proceeds  of  $22 million,  and  recognized  an 
aggregate net gain of $13 million.  See “—Liquidity and Capital Resources—Drilling fleet.” 

Impairments of long lived assets—In the year ended December 31, 2016, as a result of impairment testing, we determined 
that  our  deepwater  asset  group  was  impaired,  and  we  recognized  a  loss  of  $52 million,  which  had  no  tax  effect,  associated  with  the 
impairment  of  these  held  and  used  assets.    In  the  year  ended  December 31,  2016,  we  committed  to  a  plan  to  sell  for  scrap  value 
three deepwater  floaters  and  eight midwater  floaters,  along  with  related  equipment.    As  a  result,  we  recognized  an  aggregate  loss  of 
$41 million ($39 million, net of tax), associated with the impairment of these held for sale assets.  See “—Operating Results”, “—Liquidity 
and Capital Resources—Drilling fleet” and Notes to Consolidated Financial Statements—Note 6—Impairments. 

Markets  for  our  shares—Our  shares  are  listed  on  the  New  York  Stock  Exchange  under  the  ticker  symbol  “RIG”  and  were 
previously listed on the SIX Swiss Exchange (“SIX”) under the symbol “RIGN”.  Effective March 31, 2016, at our request, our shares were 
delisted from the SIX. 

Par value reduction—On October 29, 2015, at our extraordinary general meeting, our shareholders approved the reduction of 
the par value of each of our shares to CHF 0.10 from the original par value of CHF 15.00.  The reduction of the par value became effective 
as of January 7, 2016 upon registration in the commercial register. 

Outlook 

Drilling market—Our long term view of the offshore drilling market remains  positive, particularly for high-specification assets.  
However, although commodity pricing has improved over the past few months, our customers continue to focus on cost reduction, debt 
reduction and maintaining their current level of dividend payments.  As such, we expect them to continue to limit spending on offshore 
exploration and development opportunities in 2017.  The risks of drilling project delays, contract renegotiations and contract terminations 
remain in the near term.  Additionally, as a result of current market conditions, we have observed an increased number of requests for 
nonstandard  contractual  terms,  including  extended  payment  terms.    During  the  year  ended  December 31,  2016,  our  customers  early 
terminated  or  cancelled  drilling  contracts  for  Deepwater Asgard,  Deepwater Champion,  Deepwater Millennium,  Discoverer Deep Seas, 
Discoverer India,  GSF Constellation II,  GSF Development Driller I  and  Transocean John Shaw.    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. 

As expected, few new contracts were awarded during the year ended December 31, 2016, resulting in falling rig utilization rates 
negatively  impacting  dayrates.    Over  time,  we  believe  the  current  oil  supply  and  demand  imbalance  will  narrow.    As  spare  oil  capacity 
diminishes, we expect upward pressure on commodity pricing with subsequent increased demand for drilling rigs. 

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

As  of  February 9,  2017,  uncommitted  fleet  rates  for  each  of  the  five  years  in  the  period  ending  December 31,  2021  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. 

In  December 2016,  a  subsidiary  of  Chevron Corporation  (together  with  its  affiliates,  “Chevron”)  issued  a  notice  of  early 
termination of the drilling contract for Deepwater Asgard, effective February 3, 2017.  In January 2017, Chevron adjusted the termination 
date  to  be  January 13,  2017.    As  a  result  of  the  termination,  our  contract  backlog  for  ultra-deepwater  floaters  reflects  a  reduction  of 
approximately $110 million to remove the backlog related to this contract. 

At February 9, 2017, 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.

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

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

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

Depreciation  expense  decreased  for  the  year  ended  December 31,  2016  compared  to  the  year  ended  December 31,  2015 
primarily  due  to  the  following:  (a) approximately  $87 million  of  decreased  depreciation  primarily  resulting  from  the  impairment  of  our 
deepwater floater and midwater floater asset groups in the prior year and (b) approximately $40 million of decreased depreciation resulting

from rigs sold or classified as held for sale, partially offset by (c) approximately $66 million of increased depreciation associated with our 
newbuild ultra-deepwater drillships and other property and equipment placed into service in the year ended December 31, 2016. 

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

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

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

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

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

Income tax expense—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, 2016 and 2015, our effective tax rate, excluding discrete items, 
was 18.5 percent and 14.4 percent, respectively, based on income from continuing operations before income tax expense, after excluding 
certain items, such as losses on impairment, and gains and losses on certain asset disposals.  Our effective tax rate increased in the year 
ended December 31, 2016 compared to the year ended December 31, 2015, primarily due to (a) changes in the relative blend of income 
from operations in certain jurisdictions and (b) valuation allowances on deferred tax assets for losses not expected to be realized.  We 
consider the tax effect, if any, of the excluded items as well as settlements of prior-year tax estimates to be discrete period tax expenses or 
benefits.  In the years ended December 31, 2016 and 2015, the effect of the various discrete period tax items was a net tax benefit of 
$50 million and $75 million, respectively.  For the years ended December 31, 2016 and 2015, these discrete tax items, coupled with the 
excluded income and expense items noted above, resulted in an effective tax rate of 11.5 percent and 11.9 percent, respectively, based on 
income from continuing operations before income tax expense. 

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  marginal  tax  rate  is  lower  than  our  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  effective  tax  rate  calculation  for  the  year 
ended December 31, 2016, a significant portion of our income tax expense was generated in countries in which income taxes are imposed 
on gross revenues, with the most significant of these countries being Angola.  Conversely, the countries in which we incurred the most 
significant income taxes during this period that were based on income before income tax include Norway, Switzerland, the U.K. and the 
U.S. 

Our  rig  operating  structures  further  complicate  our  tax  calculations,  especially  in  instances  where  we  have  more  than 
one operating  structure  for  the  particular  taxing  jurisdiction  and,  thus,  more  than  one method  of  calculating  taxes  depending  on  the 
operating structure utilized by the rig under the contract.  For example, two rigs operating in the same country could generate significantly 
different provisions for income taxes if they are owned by two different subsidiaries that are subject to differing tax laws and regulations in 
the respective country of incorporation.

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 resulting from drilling contracts early terminated or cancelled by our customers. 

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  in  the  year  ended 
December 31, 2015, 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

two newbuild  ultra-deepwater  drillships  that  commenced  operations  in  the  year  ended  December 31,  2014  and  (c) approximately 
$45 million of increased depreciation resulting from our completion of other construction projects. 

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

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, our effective tax rate, excluding discrete items, 
was 14.4 percent and 16.4 percent, respectively, based on income from continuing operations before income tax expense, after excluding 
certain items, such as losses on impairment, and gains and losses on certain asset disposals.  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.  In the years ended December 31, 2015 and 2014, the effect of the various discrete period tax items was a net tax benefit of 
$75 million and $143 million, respectively.  For the years ended December 31, 2015 and 2014, these discrete tax items, coupled with the 
excluded income and expense items noted above, resulted in an effective tax rate of 11.9 percent and (5.0) 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

typically lead to higher effective tax rates, while significant increases in income before income taxes can lead to lower effective tax rates, 
subject  to  the  other  factors  impacting  income  tax  expense  noted  above.    With  respect  to  the  effective  tax  rate  calculation  for  the  year

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

Liquidity and Capital Resources 

Sources and uses of cash 

At December 31, 2016, we had $3.1 billion in cash and cash equivalents.  In the year ended December 31, 2016, 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; net proceeds from the issuance of debt and net proceeds from restricted cash investments.  Our primary 
uses  of  cash  were  capital  expenditures,  primarily  associated  with  our  newbuild  construction  projects,  repayment  of  debt  at  scheduled 
maturities,  settlement  of  the  Tendered  Notes,  debt  repurchased  in  the  open  market  and  payment  of  scheduled  installments  for  our 
Macondo well incident settlement obligations.

Net cash provided by operating activities decreased primarily due to reduced operating activities and a decrease of $633 million 
associated with cash proceeds from insurance recoveries and cost reimbursements related to the Macondo well incident, partially offset by 
a decrease of $200 million of cash paid for scheduled installments under our Macondo well incident settlement obligations and increase of 
$53 million received from customers for early terminations or cancellations of drilling contracts.

9.00% Senior Notes, the 7.75% Senior Secured Notes and the 6.25% Senior Secured Notes in the current year with no comparable activity 
in the prior year and (b) cash used to pay our shareholders installments of distributions of qualifying additional paid-in capital in the prior 
year with no comparable activity in the current year, partially offset by (c) increased cash used to repay debt in connection with scheduled 
maturities, our tender offer, open market repurchases and redemption and (d) cash deposited into cash accounts restricted for financing 
activities, primarily for the payment of principal amounts of our senior secured notes in the current year with no comparable activity in the 
prior year.

Sources and uses of liquidity 

Overview—We expect to use existing cash balances, internally generated cash flows, borrowings under our existing bank credit 
agreement, proceeds from the disposal of assets or proceeds from the issuance of additional debt to fulfill anticipated obligations, which 
may include capital expenditures, working capital and other operational requirements, scheduled debt maturities or other payments.  We 
may also consider establishing additional financing arrangements with banks or other capital providers.  Subject to market conditions and 
other factors, we may also be required to provide collateral for future financing transactions.  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. 

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.    During  the  year  ended 
December 31, 2016 and in January 2017, the same three credit rating agencies further downgraded our Debt Rating.  Such downgrades 
have  caused  and  the  recent  downgrades  will  cause  us  to  experience  increased  fees  under  our  credit  facility  and  interest  rates  under 
agreements governing certain of our senior notes.  Further downgrades may affect or limit our ability to access debt markets in the future.  
Our ability to access such markets may be severely restricted at a time when we would like, or need, to access such markets, which could 
have an impact on our flexibility to react to changing economic and business conditions.  An economic downturn could have an impact on 
the lenders participating in our credit facilities or on our customers, causing them to fail to meet their obligations to us. 

Our internally generated cash 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. 

Debt  issuances—On  July 21,  2016,  we  completed  an  offering  of  an  aggregate  principal  amount  of  $1.25 billion  of  the 
9.00% Senior Notes, and we received aggregate cash proceeds of $1.21 billion, net of initial discount and costs payable by us.  We used 
the majority of the net proceeds from the debt offering to complete the Tender Offer (see “Debt tender offer”).  We will pay interest on the 
9.00% Senior Notes semiannually on January 15 and July 15 each year, beginning on January 15, 2017. 

On October 19, 2016 and December 8, 2016, we completed an offering of an aggregate principal amount of $600 million of the 
7.75% Senior  Secured  Notes  and  $625 million  of  the  6.25% Senior  Secured  Notes,  respectively,  and  we  received  aggregate  cash 
proceeds  of  $583 million  and  $609 million,  respectively,  net  of  initial  discount  and  costs  payable  by  us.    We  will  pay  interest  on  the 
7.75% Senior Secured Notes semiannually on April 15 and October 15 of each year, beginning April 15, 2017.  We will pay interest on the 
6.25% Senior  Secured  Notes  semiannualy  on  June 1  and  December 1  of  each  year,  beginning  June 1,  2017.    Additionally,  on  each 
interest payment date, we will be required to redeem, on a pro rata basis, an aggregate principal amount of $30 million and $31 million of 
the  7.75% Senior  Secured  Notes  and  the  6.25% Senior  Secured  Notes,  respectively.    Additionally,  the  indentures  that  govern  the 
7.75% Senior Secured Notes and the 6.25% Senior Secured Notes contain covenants that limit the ability of our subsidiaries that own or 
operate the Deepwater Thalassa and Deepwater Proteus to declare or pay dividends and impose a maximum collateral rig leverage ratio 
(“Maximum Collateral Ratio”), represented by each rig’s earnings relative to the debt balance, that changes over the terms of the notes.  At 
December 31,  2016,  the  Maximum  Collateral  Ratio  under  both  indentures  was  5.75:1.00,  and  the  collateral  leverage  ratio  of  each 
subsidiary was less than 5.00:1.00. 

Debt scheduled maturity—On the scheduled maturity date of December 15, 2016, we made a cash payment of $938 million to 

repay the outstanding 5.05% Senior Notes due December 2016, at a price equal to 100 percent of the aggregate principal amount. 

Debt  tender  offer—On  August 1,  2016,  we  completed  the  Tender  Offer  to  purchase  for  cash  up  to  $1.0 billion  aggregate 
principal amount of the Tendered Notes.  As a result of the Tender Offer, we received valid tenders from holders of an aggregate principal 
amount  of  $981 million  of  the  Tendered  Notes,  and  in  the  year  ended  December 31,  2016,  we  made  an  aggregate  cash  payment  of 
$876 million to settle the Tendered Notes. 

Debt repurchases and redemption—In the years ended December 31, 2016 and 2015, we repurchased in the open market an 
aggregate  principal  amount  of  $399 million  and  $503 million,  respectively,  of  our  debt  securities  for  an  aggregate  cash  payment  of 
$354 million and $468 million, respectively.  On July 30, 2015, we redeemed the remaining aggregate principal amount of $893 million of 
the 4.95% Senior Notes for an aggregate cash payment of $904 million.  During the year ended December 31, 2014, we redeemed an 
aggregate  principal  amount  of  $207 million  of  the  outstanding  4.95% Senior  Notes  for  an  aggregate  payment  of  $216 million.    We  also 
repaid borrowings under a credit facility, established by one of our subsidiaries, and terminated this credit facility and an undrawn secured 
credit facility. 

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 

AR-41 

liability  of  $218 million  for  the  distribution  payable,  recorded  in  other  current  liabilities,  with  a  corresponding  entry  to  additional  paid-in 
capital.  On June 17 and September 23, 2015, we paid the first two installments in the aggregate amount of $109 million to shareholders of 
record as of May 29, and August 25, 2015.  On October 29, 2015, at our extraordinary general meeting, our shareholders approved the 
cancellation of the third and fourth installments of the distribution. 

In May 2014, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in 
the form of a U.S. dollar denominated dividend of $3.00 per outstanding share, payable in four quarterly installments, subject to certain 
limitations.    On  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 did 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 plc. together with its affiliates (“BP”) to settle various disputes remaining between the parties with respect to the Macondo well incident.  
Pursuant to the terms of the agreement, we received from BP 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, in the year ended December 31, 2015, 
we received aggregate cash proceeds of $538 million from insurance for recovery of previously incurred losses. 

On  May 29,  2015,  together  with  the  Plaintiff  Steering  Committee  (the  “PSC”),  we  filed  a  settlement  agreement  (the  “PSC 
Settlement Agreement”) in which we agreed to pay a total of $212 million, plus up to $25 million for partial reimbursement of attorneys’ 
fees, to resolve  (1) punitive damages claims of private plaintiffs, businesses, and local governments and (2) certain claims that BP had 
made against us and had assigned to private plaintiffs who previously settled economic damages claims against BP.  The PSC Settlement 
Agreement is subject to approval by the U.S. District Court for the Eastern District of Louisiana (the “MDL Court”) and acceptance by a 
minimum number of plaintiffs.  In June 2016 and August 2015, we made a cash deposit of $25 million and $212 million, respectively, into 
an escrow account pending approval of the settlement by the MDL Court.  As of February 16, 2017, the aggregate cash balance of our 
escrow accounts was $237 million. 

Effective 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.  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 each of the years ended December 31, 2016, 2015 
and  2014,  we  made  an  aggregate  cash  payment  of  $60 million.    On  February 14,  2017,  we  made  an  aggregate  cash  payment  of 
$60 million, representing the final installment due under the Plea Agreement. 

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 made an aggregate cash payment of $204 million and $412 million, 
respectively, including interest, representing the final installments due under the Consent Decree. 

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 traded 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  held  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. 

In the year ended December 31, 2016, Transocean Partners declared and paid an aggregate distribution of $99 million, of which 
$28 million was paid to holders of noncontrolling interest.  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.  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.

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.    Under  the  program,  Transocean Partners  repurchased 
478,376 of its publicly held common units for an aggregate purchase price of $4 million. 

On  December 9,  2016,  Transocean Partners  completed  a  merger  with  one  of  our  subsidiaries  as  contemplated  under  the 
Merger Agreement.    Following  the  completion  of  the  merger,  Transocean Partners  became  a  wholly  owned  indirect  subsidiary  of 
Transocean Ltd.    Each  Transocean Partners  common  unit  that was  issued  and  outstanding  immediately  prior  to  the  closing,  other  than 
units held by Transocean and its subsidiaries, was converted into the  right to receive 1.20 of our shares.  To complete the merger, we 
issued 23.8 million shares from conditional capital. 

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, 2016, 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 based on our Debt Rating.  At February 16, 2017, based on our Debt Rating 
on that date, the Five-Year Revolving Credit Facility Margin was 2.0 percent and the facility fee was 0.35 percent.  At February 16, 2017, 
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. 

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  $3.4 billion.    On  February 12,  2010,  our  board  of  directors  authorized  our  management  to 
implement  the  share  repurchase  program.    At  December 31,  2015,  we  held  2.9 million  of  our  shares.    On  October 29,  2015,  at  our 
extraordinary general meeting, our shareholders approved the cancellation of all shares repurchased to date under our share repurchase 
program.  In January 2016, upon registration of the cancellation in the commercial register, all repurchased shares were cancelled.  In the 
three-year period ended December 31, 2016, we did not purchase shares under our share repurchase program. 

We intend to fund any repurchases using available cash balances and cash from operating activities.  Based upon our ongoing 
capital  requirements,  the  price  of  our  shares,  regulatory  and  tax  considerations,  cash  flow  generation,  the  amount  and  duration  of  our 
contract backlog, general market conditions, debt ratings considerations and other factors, we may elect to retain cash, reduce debt, make 
capital  investments  or  acquisitions  or  otherwise  use  cash  for  general  corporate  purposes,  and  consequently,  we  may  elect  not  to 
repurchase any 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 repurchased shares under the share repurchase program would be held by us for 
cancellation  by  the  shareholders  at  a  future  general  meeting  of  shareholders.    The  share  repurchase  program  could  be  suspended  or 
discontinued  by  our  board  of  directors  or  company  management,  as  applicable,  at  any  time.    At  February 16,  2017,  the  authorization 
remaining under the share repurchase program was for the repurchase of up to CHF 3.2 billion, equivalent to approximately $3.2 million of 
our  outstanding  shares.    See  “Item 5.  Market  for  Registrant’s  Common  Equity,  Related  Shareholder  Matters  and  Issuer  Purchases  of 
Equity Securities—Shareholder Matters.”

(a) 
(b) 

Includes scheduled installments of principal and imputed interest on our capital lease obligation. 
In  the  year  ended  December 31,  2016,  we  entered  into  long-term  service  agreements  with  certain  original  equipment  manufacturers  to  provide 
services and parts related to our pressure control systems.  The future payments required under our service agreements were estimated based on 
our projected operating activity and may vary based on actual operating activity. 

(c)  As of December 31, 2016, our defined benefit pension and other postretirement plans represented an aggregate liability of $375 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 12—Postemployment Benefit Plans. 
As of December 31, 2016, our unrecognized tax benefits related to uncertain tax positions, net of prepayments, represented a liability of $370 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 7—Income Taxes. 

Other  commercial  commitments—We  have  other  commercial  commitments  that  we  are  contractually  obligated  to  fulfill  with 
cash under certain circumstances.  These commercial commitments include standby letters of credit and surety bonds that guarantee our 
performance as it relates to our drilling contracts, insurance, customs, tax and other obligations in various jurisdictions.  Standby letters of 
credit are issued under various uncommitted credit lines, some of which require cash collateral.  At December 31, 2016, the aggregate 
cash collateral held by banks for letters of credit was $5 million.  The obligations that are the subject of these standby letters of credit and 
surety bonds are primarily geographically concentrated in 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, 2016, 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, 2016, the 
cash investments held by the captive insurance company totaled $209 million, and the amount of such cash investments is expected to 
range  from  $75 million  to  $215 million  by  December 31,  2017.    The  amount  of  actual  cash  investments  held  by  the  captive  insurance 
company varies, depending on the amount of premiums paid to the captive insurance company, the timing and amount of claims paid by 
the captive insurance company, and the amount of dividends paid by the captive insurance company. 

Drilling fleet 

Expansion—From time to time, we review possible acquisitions of businesses and drilling rigs and may make significant future 
capital commitments for such purposes.  We may also consider investments related to major rig upgrades, new rig construction, or the 
acquisition of a rig under construction.  We may commit to such investment without first obtaining customer contracts.  Any acquisition, 
upgrade or new rig construction could involve the payment by us of a substantial amount of cash or the issuance of a substantial number 
of additional shares or other securities.  Our failure to secure drilling contracts for rigs under construction could have an adverse effect on 
our results of operations or cash flows.

In  the  years  ended  December 31,  2016  and  2015,  we  made  capital  expenditures  of  $1.3 billion  and  $2.0 billion,  respectively, 
including $1.2 billion and $1.6 billion, respectively, for our major construction projects.  For the year ending December 31, 2017, we expect 
total  capital  expenditures  and  other  capital  additions  to  be  approximately  $500 million,  including  $431 million  for  our  major  construction 
projects. 

As  of  December 31,  2016,  the  historical  and  projected  capital  expenditures  and  other  capital  additions,  including  capitalized

(a)  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. 

(b)  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 2020, the second quarter of 2020, the third quarter of 2020, the fourth quarter of 2020 and the fourth quarter of 2020, respectively.  The 
delivery  expectations  and  the cost  projections  presented above  reflect  the  terms  of  our  construction  agreements,  as amended  to  delay  delivery  in  consideration  of 
current market conditions. 

(c)  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 first quarter of 2020 and the third quarter of 2020, respectively.  The delivery expectations and the cost projections presented 
above reflect the terms of our construction agreements, as amended to delay delivery in consideration of current market conditions. 

The  ultimate  amount  of  our  capital  expenditures  is  partly  dependent  upon  financial  market  conditions,  the  actual  level  of 
operational  and  contracting  activity,  the  costs  associated  with  the  current  regulatory  environment  and  customer  requested  capital 
improvements and equipment for which the customer agrees to reimburse us.  As with any major shipyard project that takes place over an 
extended period of time, the actual costs, the timing of expenditures and the project completion date may vary from estimates based on 
numerous factors, including actual contract terms, weather, exchange rates, shipyard labor conditions, availability of suppliers to recertify 
equipment  and  the  market  demand  for  components  and  resources  required  for  drilling  unit  construction.    We  intend  to  fund  the  cash 
requirements relating to our capital expenditures through available cash balances, cash generated from operations and asset sales.  We 
also have available credit under the Five-Year Revolving Credit Facility 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 years  ended 
December 31, 2016, 2015 and 2014, we identified seven, 22 and two such drilling units, respectively, that we have sold or intend to sell for 
scrap value.  We continue to evaluate the drilling units in our fleet and may identify additional lower-specification drilling units to be sold for 
scrap value. 

During the year ended December 31, 2016, we completed the sale of three deepwater floaters and eight midwater floaters, along 
with  related  equipment,  and  we  received  aggregate  net  cash  proceeds  of  $22 million.    During  the  year  ended  December 31,  2015,  we 
completed the sale of two ultra-deepwater floaters, six deepwater floaters and nine midwater floaters, along with related equipment, and 
we  received  aggregate  net  cash  proceeds  of  $35 million.    During  the  year  ended  December 31,  2014,  we  completed  the  sale  of 
one deepwater floater, one midwater floater and two high-specification jackups, along with related equipment, and we received aggregate 
net cash proceeds of $185 million. 

Pension Plans and Other Postretirement Benefit Plans 

Overview—Benefits  under  all  of  our  U.S.  defined  benefit  pension  plans  have  ceased  accruing.    We  maintain  the  respective 
pension  obligations  under  such  plans  until  they  have  been  fully  satisfied.    As  of  December 31,  2016,  we  maintained  three funded  and 
three unfunded  defined  benefit  plans  in  the  U.S.  (the  “U.S.  Plans”).    During  the  year  ended  December 31,  2016,  we  permitted  certain

participants of one of our funded U.S. Plans to make a one-time election to receive a payment of retirement benefits in the form of either 
(a) a lump sum distribution or (b) an annuity starting October 1, 2016. 

As of December 31, 2016, we maintained one defined benefit plan in the U.K. (the “U.K. Plan”), under which we and the plan 
trustees mutually agreed to cease accruing benefits effective March 31, 2016.  As of December 31, 2016, we also maintained two 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”).  During the year ended December 31, 2016, we satisfied our obligations 
under  four funded  defined  benefit  plans  in  Norway  and  the  unfunded  defined  benefit  plans  in  Nigeria.    During  the  year  ended 
December 31, 2015, we satisfied our obligations under the unfunded defined benefit plans in Egypt and Indonesia.  We refer to the U.K. 
Plan, the Norway Plans and the plans in Nigeria, Egypt and Indonesia, collectively, as the “Non-U.S. Plans.” 

We refer to the U.S. Plans and the Non-U.S. Plans, collectively,  as the “Transocean Plans.”  Additionally, we maintain certain 
unfunded  other  postretirement  employee  benefit  plans  (collectively,  the  “OPEB Plans”),  under  which  benefits  to  eligible  participants 
diminish during a phase-out period ending December 31, 2025. 

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

Non-U.S. Plans and the OPEB Plans.

(c)  Weighted-average based on relative average fair value of plan assets for the year. 

Net  periodic  benefit  cost—In  the  years  ended  December 31,  2016  and  2015,  net  periodic  benefit  costs  were  reduced  by 
$105 million  and  $115 million,  respectively,  for  expected  returns  from  plan  assets.    In  the  year  ended  December 31,  2016,  net  periodic 
benefit costs decreased $37 million.  In the year ending December 31, 2017, we expect our net periodic benefit costs to be approximately 
the same as the costs recognized in the year ended December 31, 2016. 

Plan assets—In the year ended December 31, 2016, 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, 2016, the fair value of the investments in the funded Transocean Plans decreased by $33 million, or two percent, primarily 
due  to  the  following:  $130 million  resulting  from  benefits  and  settlements  paid  from  plan  assets,  net  of  contributions,  and  $80 million 
resulting  from  net  losses  on  currency  exchange  rate  changes  for  our  non-U.S.  Plans,  partially  offset  by  $177 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  qualified  U.S.  Plan,  we  contribute  an  amount  at  least  equal  to  that  required  by  the

Employee  Retirement  Income  Security  Act  of  1974  (“ERISA”)  and  the  Pension  Protection  Act  of  2006  (“PPA”).    We  use  actuarial 
computations to establish the minimum contribution required under ERISA and PPA and the maximum deductible contribution allowed for 
income tax purposes.  For the funded U.K. Plan, we contribute an amount, as mutually agreed with the plan trustees, based on actuarial 
recommendations.  For the funded Norway Plans, we contribute an amount determined by the plan trustee based on Norwegian pension 
laws.  For the unfunded Transocean Plans and OPEB Plans, we generally fund benefit payments for plan participants as incurred.  We 
fund our contributions to the Transocean Plans and the OPEB Plans using cash flows from operations. 

In 

the  year  ended  December 31,  2016,  we  contributed  $49 million  and  participants  contributed  $1 million 

the 
Transocean Plans and the OPEB Plans.  In the year ended December 31, 2015, we contributed $39 million and participants contributed 
$4 million to the Transocean Plans and the OPEB Plans.  For the year ending December 31, 2017, we expect to contribute $11 million to 
the Transocean Plans and $3 million to the OPEB Plans.

Contingencies and Uncertainties 

Macondo well incident 

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  and  the  States.    Additionally,  we  entered  into  the  PSC Settlement  Agreement,  which  remains  subject  to 
approval  by  the  MDL  Court.    We  believe  the  remaining  most  notable  claims  against  us  arising  from  the  Macondo  well  incident  are  the 
30 settlement  class  opt  outs  from  the  PSC  Settlement  Agreement.    We  can  provide  no  assurance  as  to  the  outcome  of  the  remaining 
claims arising from the Macondo well incident, 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 13—Commitments and Contingencies and Note 23—Subsequent Events. 

Regulatory matters 

On  February 25,  2013,  we  and  the  U.S.  Environmental  Protection  Agency  (the  “EPA”)  entered  into  an  agreement  (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.   For a description of regulatory and environmental matters relating to the Macondo well incident, please see “—Macondo well 
incident.”  See also Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies. 

Tax matters 

We conduct operations through our various subsidiaries in a number of countries throughout the world.  Each country has its own 
tax regimes with varying nominal rates, deductions and tax attributes.  From time to time, we may identify changes to previously evaluated 
tax positions that could result in adjustments to our recorded assets and liabilities.  Although we are unable to predict the outcome of these 
changes,  we  do  not  expect  the  effect,  if  any,  resulting  from  these  adjustments  to  have  a  material  adverse  effect  on  our  consolidated 
statement of financial position, results of operations or cash flows. 

We  file  federal  and  local  tax  returns  in  several  jurisdictions  throughout  the  world.    Tax  authorities  in  certain  jurisdictions  are 
examining our tax returns and in some cases have issued assessments.  We are defending our tax positions in those jurisdictions.  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.    On 
January 9, 2017, the Norwegian appeal court in Oslo ruled entirely in favor of the Transocean subsidiaries and overturned the district court 
with  respect  to  the  remaining  question  of  principal  tax  obligations.    On  February 10,  2017,  the  tax  authorities  filed  an  appeal  with  the 
Norwegian Supreme Court.  While we cannot predict or provide assurance as to the final outcome of these proceedings, we do not expect 
the ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations, although it 
may have a material adverse effect on our consolidated cash flows. 

See Notes to Consolidated Financial Statements—Note 7—Income Taxes and Note 23—Subsequent Events. 

AR-47 

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, 2016. 

Related Party Transactions 

As  of  December 31,  2016,  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 consider the following to be our critical accounting policies and estimates since they are very important to the 
portrayal  of  our  financial  condition  and  results  and  require  our  most  subjective  and  complex  judgments.    We  have  discussed  the 
development, selection and disclosure of such policies and estimates with the audit committee of our board of directors.  For a discussion 
of our significant accounting policies, refer to our Notes to Consolidated Financial Statements—Note 2—Significant Accounting Policies. 

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the U.S., which 
require  us  to  make  estimates  that  affect  the  reported  amounts  of  assets,  liabilities,  revenues,  expenses  and  related  disclosures  of 
contingent assets and liabilities.  These estimates require significant judgments and assumptions.  We base our estimates on historical 
experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis 
for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources.  Actual results 
may differ from these estimates. 

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

Our annual tax provision is based on expected taxable income, statutory rates and tax planning opportunities available to us in 
the various jurisdictions in which we operate.  The determination of our annual tax provision and evaluation of our tax positions involves 
interpretation of tax laws in the various jurisdictions and requires significant judgment and the use of estimates and assumptions regarding 
significant future events, such as the amount, timing and character of income, deductions and tax credits.  Our tax liability in any given year 
could be affected by changes in tax laws, regulations, agreements, and treaties, currency exchange restrictions or our level of operations 
or profitability in each jurisdiction.  Additionally, we operate in many jurisdictions where the tax laws relating to the offshore drilling industry 
are not well developed.  Although our annual tax provision is based on the best information available at the time, a number of years may 
elapse before the tax liabilities in the various jurisdictions are ultimately determined. 

We 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, 
2016, the liability for estimated tax exposures in our jurisdictions of operation was approximately $370 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 
impartiality  of  the  local  courts;  and  the  potential  for  changes  in  the  taxes  paid  to  one country  that  either  produce,  or  fail  to  produce, 
offsetting tax changes in other countries. 

We do not provide for taxes on unremitted earnings of subsidiaries when we consider such earnings to be indefinitely reinvested.  
We recognize deferred taxes related to the earnings of certain subsidiaries that we do not consider to be indefinitely reinvested or that will 

AR-48 

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.    At  December 31,  2016,  the  amount  of  indefinitely  reinvested  earnings  was 
approximately $2.5 billion.  Should we make a distribution from the unremitted earnings of these subsidiaries, we could 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, 2016. 

Estimates, judgments and assumptions are required in determining whether deferred tax assets will be fully or partially realized.  
In evaluating our ability to realize deferred tax assets, we consider all available positive and negative evidence, including projected future 
taxable income and the existence of cumulative losses in recent years.  When it is estimated to be more likely than not that all or some 
portion of certain deferred tax assets, such as foreign tax credit carryovers or net operating loss carryforwards, will not be realized, we 
establish a valuation allowance for the amount of the deferred tax assets that is considered to be unrealizable.  We continually evaluate 
strategies that could allow for the future utilization of our deferred tax assets.  During the year ended December 31, 2016, in evaluating our 
projected  realizability  of  deferred  tax  assets,  we  took  into  account  plans  to  combine  certain  subsidiaries.    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 year 
ended December 31, 2014, we did not make any significant changes to our valuation allowance against deferred tax assets. 

See Notes to Consolidated Financial Statements—Note 7—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, 2016 and 2015, the carrying 
amount of our property and equipment was $21.1 billion and $20.8 billion, representing 78 percent and 79 percent, respectively, of our total 
assets. 

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

Useful lives and salvage values—We depreciate our assets using the straight-line method over their estimated useful lives after 
allowing  for  salvage  values.    We  estimate  useful  lives  and  salvage  values  by  applying  judgments  and  assumptions  that  reflect  both 
historical experience and expectations regarding future operations, rig utilization and asset performance.  Useful lives and salvage values 
of rigs are difficult to estimate due to a variety of factors, including (a) technological advances that impact the methods or cost of oil and 
gas  exploration  and  development,  (b) changes  in  market  or  economic  conditions,  and  (c) changes  in  laws  or  regulations  affecting  the 
drilling industry.  Applying different judgments and assumptions in establishing the useful lives and salvage values would likely result in 
materially different net carrying amounts and depreciation expense for our assets.  We reevaluate the remaining useful lives and salvage 
values  of  our  rigs  when  certain  events  occur  that  directly  impact  the  useful  lives  and  salvage  values  of  the  rigs,  including  changes  in 
operating condition, functional capability and market and economic factors.  When evaluating the remaining useful lives of rigs, we also 
consider major capital upgrades required to perform certain contracts and the long-term impact of those upgrades on future marketability.  
At  December 31,  2016,  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  $49 million  and  a  hypothetical  one-year  decrease  would  cause  an  increase  in  our  annual 
depreciation expense of approximately $53 million. 

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

AR-49 

fair  value  generally  requires  us  to  use  significant  unobservable  inputs,  representative  of  a  Level 3  fair  value  measurement,  including 
assumptions  related  to  the  long-term  future  performance  of  our  asset  groups,  such  as  projected  revenues  and  costs,  dayrates,  rig 
utilization and revenue efficiency.  These projections involve uncertainties that rely on assumptions about demand for our services, future 
market conditions and technological developments.  Because our business is cyclical in nature, the results of our impairment testing are 
expected to vary significantly depending on the timing of the assessment relative to the business cycle.  Altering either the timing of or the 
assumptions used to estimate fair value and significant unanticipated changes to the assumptions could materially alter an outcome that 
could  otherwise  result  in  an  impairment  loss.    Given  the  nature  of  these  evaluations  and  their  application  to  specific  asset  groups  and 
specific time periods, it is not possible to reasonably quantify the impact of changes in these assumptions. 

In  the  year  ended  December 31,  2016,  we  recognized  a  loss  of  $52 million,  which  had  no  tax  effect,  associated  with  the 
impairment  of  the  deepwater  floater  asset  group.    In  the  year  ended  December 31,  2015,  we  recognized  losses  of  $507 million 
($481 million, net of tax) and $668 million ($654 million, net of tax) associated with the impairment of the deepwater floater asset group and 
the midwater floater asset group, respectively.  In the year ended December 31, 2014, we recognized a loss of $788 million ($693 million, 
net of tax) associated with the impairment of the deepwater floater asset group. 

See Notes to Consolidated Financial Statements—Note 6 Impairments. 

Revenue recognition—Our contracts to provide offshore drilling services are individually negotiated and vary in their terms and 
provisions.    We  obtain  most  of  our  drilling  contracts  through  competitive  bidding  against  other  contractors  and  direct  negotiations  with 
operators.    Drilling  contracts  generally  provide  for  payment  on  a  dayrate  basis,  with  higher  rates  for  periods  while  the  drilling  unit  is 
operating and lower rates or zero rates for periods of mobilization or when drilling operations are interrupted or restricted by equipment 
breakdowns, adverse environmental conditions or other conditions beyond our control.  A dayrate drilling contract generally extends over a 
period of time covering either the drilling of a single well or group of wells or covering a stated term.  We recognize operating revenues as 
they  are  realized  and  earned  and  can  be  reasonably  measured,  based  on  contractual  dayrates,  and  when  collectability  is  reasonably 
assured.  For contractual daily rate contracts, we recognize the losses for loss contracts as such losses are incurred. 

Certain of our drilling contracts may be cancelable for the convenience of the customer upon payment of an early termination 
payment.    We  recognize  revenues,  presented  in  other  revenues,  associated  with  cancellations  or  early  terminations  over  the  period  in 
which we satisfy our performance obligations based on the negotiated or contractual terms, which are typically specific to the contractual 
arrangement.  In the years ended December 31, 2016 and 2015, we recognized revenues of $471 million and $505 million, respectively, 
associated with cancellations and early terminations. 

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,  2016  and  2015,  the 
liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $250 million, 
recorded in other current liabilities. 

See Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies. 

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 are actuarially determined and are affected by assumptions, including long-term rate of return, discount rates, 
mortality  rates  and  employee  turnover  rates.    Because  our  defined  benefit  plans  have  ceased  accruing  benefits,  certain  assumptions, 

AR-50 

including compensation increases and health care cost trend rates no longer apply.  The two most critical assumptions are the long-term 
rate  of  return  and  the  discount  rate.    For  the  long-term  rate  of  return  of  plan  assets,  we  develop  our  assumptions  based  on  historical 
experience and projected returns for the investments considering each plan’s target asset allocation and long-term asset class expected 
returns.  For the discount rate, we develop our assumptions utilizing a yield curve approach based on Aa-rated corporate bonds and the 
expected  timing  of  future  benefit  payments.    We  periodically  evaluate  our  assumptions  and,  when  appropriate,  adjust  the  recorded 
liabilities and expense.  Changes in these and other assumptions used in the actuarial computations could impact our projected benefit 
obligations,  pension  liabilities,  net  periodic  benefit  costs  and  other  comprehensive  income.    See  “—Pension  Plans  and  Other 
Postretirement Benefit Plans” and Notes to Consolidated Financial Statements—Note 12—Postemployment Benefit Plans.

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

Interest  rate  risk—At  December 31,  2016  and  2015,  the  fair  value  of  our  debt  was  $8.2 billion  and  $6.3 billion,  respectively.  
During  the  year  ended  December 31,  2016,  the  fair  value  of  our  debt  increased  by  $1.9 billion  due  to  the  following:  (a) an  increase  of 
approximately $2.6 billion resulting from the issuance of $2.5 billion aggregate principal amount of new debt during 2016, (b) a decrease of 
approximately  $1.9 billion  resulting  from  the  repurchase  or  redemption  of  $2.3 billion  aggregate  principal  amount  of  debt  and  (c) an 
increase of approximately $1.2 billion resulting from the increased 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,  2016  and  2015,  a  hypothetical 
one percentage  point  change  in  interest  rates  would  result  in  a  corresponding  change  in  annual  interest  income  of  approximately 
$31 million and $23 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. 

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 contract terms, local banking laws, other statutory requirements, local currency convertibility and the impact of inflation on local 
costs, actual local currency needs may vary, resulting in exposure to currency exchange rate risk.  The effect of fluctuations in currency 
exchange rates caused by our international operations generally has not had a material impact on our overall operating results. 

At December 31, 2016, we had NOK 1.1 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 a 
system of 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, 2016.  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, 2016, the Company’s internal control over financial reporting was 
not  effective.    Based  upon  this  evaluation,  our  Chief  Executive  Officer  and  Chief  Financial  Officer  concluded  that,  as  of  December 31, 
2016, our internal control over financial reporting was not effective due to a material weakness in our controls over income tax accounting.  
Specifically, the execution of the controls over the application of the accounting literature to the measurement of deferred taxes did not 
operate  effectively  in  relation  to:  (1) the  remeasurement  of  certain  nonmonetary  assets  in  Norway,  (2) the  analysis  of  our  U.S.  defined 
benefit pension plans liability and associated other comprehensive income and (3) the realizability of our deferred tax assets and the need 
for a valuation allowance.  As a result of the significance of the accounting errors resulting from the deficient controls, the accompanying 
financial  statements  for  2015  and  2014  have  been  revised  notwithstanding  that  management  does  not  believe  that  such  errors  were 
material for these years.  The matter was discovered during the course of the 2016 external audit of the accounts and related controls. 

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, 2016, 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. 

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is 
a  reasonable  possibility  that  a  material  misstatement  of  the  company’s  annual  or  interim  financial  statements  will  not  be  prevented  or 
detected  on  a  timely  basis.    The  following  material  weakness  has  been  identified  and  included  in  management’s  assessment.  
Management  has  identified  a  material  weakness  in  controls  related  to  the  Company’s  income  tax  process.    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,  2016  and  2015,  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, 2016.   This material 
weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the 2016 financial statements, 
and this report does not affect our report dated March 6, 2017 which expressed an unqualified opinion on those financial statements. 

In  our  opinion,  because  of  the  effect  of  the  material  weakness  described  above  on  the  achievement  of  the  objectives  of  the 
control criteria, Transocean Ltd. and subsidiaries has not maintained effective internal control over financial reporting as of December 31, 
2016, based on the COSO criteria.

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, 2016 and 2015, 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, 2016.  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, 2016 and 2015, and the consolidated results of their operations and their cash flows 
for each of the three years in the period ended December 31, 2016, 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,  2016,  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 March 6, 2017 expressed an adverse opinion thereon.

Report on the Audit of 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,  2016  and  2015,  and  the  related  consolidated  statements  of  operations, 
comprehensive  income  (loss),  equity,  cash  flows,  and  notes  thereto  (pages AR-59  to  AR-98),  for  each  of  the  three years  in  the  period 
ended December 31, 2016. 

Board of Directors’ Responsibility 

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

Auditor’s Responsibility 

Our responsibility is to express an opinion on these consolidated financial statements based on our audits.  We conducted our 
audits  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 whether the consolidated 
financial statements are free of 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 of the consolidated financial statements in order to design audit 
procedures that are appropriate in the circumstances.  An audit also includes evaluating the appropriateness of the accounting policies 
used and the reasonableness of accounting estimates made, as well as evaluating the overall presentation of the consolidated financial 
statements.  We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. 

Opinion 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated 
financial position of Transocean Ltd. as of December 31, 2016 and 2015, and the consolidated results of its operations and its cash flows 
for each of the three years in the period ended December 31, 2016, in accordance with U.S generally accepted accounting principles and 
comply with Swiss law. 

Report on Key Audit Matters based on the circular 1/2015 of the Federal Audit Oversight Authority 

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

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

AR-55 

 
 
 
 
 
 
 
 
 
 
 
 
Revenue recognition, including contract modification  

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

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

Our audit 
response 

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

We tested the effectiveness of controls over Transocean Ltd.’s review of new and amended contracts including 
the assessment of the accounting for the arrangement.  We also performed audit procedures on a sample of 
new  or  amended  drilling  contracts  to  assess  the  accounting  treatment  by  evaluating   Ltd.’s  interpretation  of 
contract terms.  We tested the accounting treatment for a sample of revenue transactions recorded as a result 
of a new, amended or terminated contract during the current fiscal year including validation that the revenue 
recognition criteria had been met and Transocean Ltd.’s performance obligations had been satisfied.  We used 
analytical procedures to identify transactions with attributes suggesting changes of terms and conditions of the 
underlying arrangement not identified through our other procedures. We performed inquiries with members of 
the  operations  management  team,  including  the  marketing  department,  to  corroborate  the  contract 
documentation obtained. 

Long-lived assets impairment 

Area of emphasis  Transocean Ltd.  reviews  the  carrying  amounts  of  long-lived  assets,  principally  property  and  equipment,  for 
potential impairment when events occur or circumstances change that indicate that the carrying amount of such 
assets  may  not  be  recoverable.    For  assets  classified  as  held  and  used,  recoverability  is  determined  by 
evaluating the estimated undiscounted future net cash flows based on projected dayrates and utilization of the 
asset  group  under  review.    Transocean Ltd.  considers  asset  groups  to  be  ultra  deepwater  floaters,  harsh 
environment  floaters,  deepwater  floaters,  midwater  floaters  and  high  specification  jackups.    When  an 
impairment of one or more asset groups is indicated, the impairment is calculated as the amount by which the 
asset group’s carrying amount exceeds its estimated fair value. 

Transocean Ltd. measures the fair values of its contract drilling asset groups by applying a variety of valuation 
methods, incorporating a combination of 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. 

The  primary  risks  are  incorrect  determination  of  asset  classes  and  subsequent  calculation  of  recoverability, 
inaccurate models being used for the impairment assessments, and that the assumptions to support the value 
of  asset  classes  are  inappropriate.    The  principal  consideration  for  our  determination  that  impairment  of 
long-lived asset is a key audit matter is the subjectivity in the assessment of the recoverable amounts, which 
requires estimation and the use of subjective assumptions. 

See  note 6  to  these  consolidated  financial  statements  for  Transocean Ltd.’s  related  to  long-lived  assets 
impairments. 

Our audit 
response 

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

We  tested  the  effectiveness  of  controls  over  Transocean Ltd.’s  long-lived  assets  impairment.    We  performed 
inquiries of management about the current market conditions supporting the evaluation of potential impairment 
indicators,  assessed  Transocean Ltd.’s  determination  of  asset  groups,  we  tested  the  key  assumptions  used, 

AR-56 

and performed procedures on Transocean Ltd.’s prospective financial information. 

We involved valuation specialists to assist in the evaluation of the impairment analyses, specifically in testing 
key assumptions and prospective financial information. 

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

We  performed  procedures  to  assess  the  valuation  models  for  evidence  of  management  bias  considering 
contrary  evidence  from  third  party  analyst  reports,  press  releases  and  fleet  status  reports  published  by 
Transocean Ltd.’s competitors. 

Uncertain tax positions 

Area of emphasis   Transocean Ltd.  evaluates  its  income  tax  positions  to  determine  whether  they  meet  the  more-likely-than-not 
threshold to be recognized in the financial statements and measures a recognized tax position at the largest 
amount  of  benefit  that  is  more  likely  than  not  of  being  realized  upon  ultimate  settlement  with  the  taxing 
authority.    There  is  subjectivity  in  determining  the  proper  amount  of  liabilities  for  tax  contingencies  and 
assessing  the  impact  of  complex  tax  structures  involves  management  judgment.    Management  continually 
monitors  the  evolving  tax  regulations  in  order  to  assess  any  new  legislation  and  quantify  the  impact  and 
changes to the overall company structure.  There is a risk of improper recognition of uncertain tax positions due 
to  the  complex  structure  of  Transocean Ltd.    The  principal  considerations  for  our  determination  that  tax 
contingencies  is  a  key  audit  matter  include  the  difficulty  in  identifying  all  matters  to  be  considered  and  the 
subjectivity related to the inputs utilized in the measurement of its exposures. 

See  note 7  to  these  consolidated  financial  statements  for  Transocean Ltd.’s  disclosures  related  to  income 
taxes. 

Our audit 
response 

Our  audit  procedures  related  to  the  key  audit  matter  of  uncertain  tax  positions  included  the  following 
procedures:  

We tested the effectiveness of controls over Transocean Ltd.’s identification and measurement of uncertain tax 
positions.    We  also  tested  significant  uncertain  tax  positions  by  evaluating  the  inputs  and  recalculating  the 
reserve recorded by Transocean Ltd.  We tested the completeness of Transocean Ltd.’s uncertain tax positions 
by  evaluating  transactions  entered  into  by  Transocean Ltd.  during  the  current  year,  inspecting  analyses 
comparing the tax return to the tax accrual and performing inquiries with management.  We also monitored tax 
regulations throughout the year and evaluated management’s assessments of any new legislation. 

We  involved  specialists  to  assist  in  gaining  an  understanding  of  Transocean Ltd.’s  uncertain  tax  positions, 
including the evaluation of external tax opinions and assessing the inputs utilized in calculating uncertain tax 
positions, including transfer pricing risks. 

Income taxes and correction of prior period financial statements  

Area of emphasis  Transocean Ltd. operates worldwide through various subsidiaries.  Due to the complex organizational structure 
of the entity and the cross-border nature of its operations, the annual tax provision is complex and based on 
expected taxable income, statutory rates and tax planning opportunities available in the various jurisdictions in 
which it operates.  The rig operating structure further complicates the tax calculations, especially in instances 
where  there  is  more  than  one  operating  structure  for  a  particular  tax  jurisdiction  and  thus,  more  than  one 
method  of  calculating  taxes.    Estimates,  judgments  and  assumptions  are  also  required  in  the  evaluation  of 
income taxes, specifically in the determination of whether deferred tax assets will be fully or partially realized. 

During  the  audit  of  the  consolidated  financial  statements  for  the  year  ended  December 31,  2016,  three prior 
period errors were identified related to the accounting for deferred taxes, including the assessment of the need 
for a valuation allowance.  These errors are material to the 2016 consolidated financial statements, but are not 
material  to  any  of  the  previously  issued  consolidated  financial  statements.    The  first  error  pertained  to  the 
accounting for the foreign currency remeasurement on deferred taxes of non-monetary temporary differences in 
Norway.  The second error pertained to the accounting for deferred taxes related to Transocean Ltd.’s defined 
benefit pension plan in the United States.  The third error pertained to a valuation allowance on deferred tax 
assets  recorded  in  the  United  Kingdom.    Related  to  the  errors  identified,  Transocean Ltd.  determined  the 
deficiencies in internal control represented a material weakness in the controls over income tax accounting as 

AR-57 

of December 31, 2016.  

See  note 7  to  these  consolidated  financial  statements  for  Transocean Ltd.’s  disclosures  related  to  income 
taxes.  See note 4 to these consolidated financial statements for Transocean Ltd.’s disclosures related to the 
correction of prior period errors.  See Management’s Report on Internal Control Over Financial Reporting for 
details on the material weakness identified.  

Our audit 
response 

Our  audit  procedures  related  to  the  key  audit  matter  of  income  taxes  and  correction  of  prior  period  financial 
statements included the following procedures:  

We  tested  the  effectiveness  of  controls  over  Transocean Ltd.’s  preparation  of  its  annual  tax  provision.    We 
tested the tax basis balance sheets and assessed the identification and accounting for differences between the 
tax basis and the book value.  We performed procedures to assess the valuation allowances recorded against 
deferred  tax  assets  in  various  jurisdictions  that  are  more  likely  than  not  to  be  utilized  and  tested 
Transocean Ltd.’s assessment of sources of future taxable income.  We involved EY tax professionals to assist 
in evaluating the income tax calculations and analyses required by ASC 740, Income Taxes.  We performed 
procedures to evaluate the amounts and disclosures within the financial statements related to income taxes. 

We  performed  procedures  to  evaluate  management’s  assessment  of  the  prior  period  errors  identified.  We 
evaluated the impact the adjustments could have on reported line items, subtotals, totals and disclosures in the 
context  of  the  prior  period  financial  statements  as  a  whole.  We  considered  the  potential  for  undetected 
misstatements  and  performed  procedures 
the  qualitative  considerations  considered  by 
management when determining materiality to the prior year financial statements.   

to  evaluate 

In response to the material weakness, we modified our risk assessment on the valuation assertion for deferred 
taxes  and  reduced  our  testing  thresholds  for  audit  procedures  related  to  deferred  tax  assets  and  liabilities, 
including  related  valuation  allowances.    In  addition,  we  performed  incremental  audit  procedures  to  test  any 
temporary differences arising from the tax basis balance sheets of certain jurisdictions considered as the high 
tax jurisdictions of Transocean Ltd.  We performed procedures to test the completeness of deferred tax assets 
and  liabilities  and  evaluated  if  there  were  any  other  high  tax  rate  jurisdictions  that  included  significant 
non-monetary assets.  

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  the  course  of  our  audit  performed  in  accordance  with  article 728a para.  1 item 3 CO  and  Swiss  Auditing  Standard 890,  we 
noted that an internal control system for the preparation of the consolidated financial statements designed according to the instructions of 
the  Board  of  Directors  was  adequately  documented.    However,  the  procedures  and  controls  over  the  income  tax  process,  a  significant 
process for the entity, were not implemented in all material respects. 

In  our  opinion,  except  for  the  matter  described  in  the  preceding  paragraph,  an  internal  control  system  for  the  preparation  of 

consolidated financial statements, designed in accordance with the instructions of the Board of Directors, exists. 

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

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, 2016, we owned or had 
partial ownership interests in and operated 56 mobile offshore drilling units, including 30 ultra-deepwater floaters, seven harsh environment 
floaters,  three deepwater  floaters,  six midwater  floaters  and  10 high-specification  jackups.    At  December 31,  2016,  we  also  had 
four ultra-deepwater drillships and five high-specification jackups under construction or under contract to be constructed.  See Note 10—
Drilling Fleet. 

Transocean Partners—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.  On December 9, 2016, Transocean Partners completed a merger with one of our 
subsidiaries as contemplated under the Agreement and Plan of Merger (the “Merger Agreement”), dated July 31, 2016, and as amended 
on  November  21,  2016.    Following  the  completion  of  the  merger,  Transocean Partners  became  a  wholly  owned  indirect  subsidiary  of 
Transocean Ltd.  Each Transocean Partners common unit that was issued and outstanding immediately prior to the closing, other than the 
units held by Transocean and its subsidiaries, was converted into  the right to receive 1.20 of our shares.  To complete the merger, we 
issued 23.8 million shares from conditional capital.  See Note 14—Noncontrolling Interest. 

Par value reduction—On October 29, 2015, at our extraordinary general meeting, our shareholders approved the reduction of 
the par value of each of our shares to CHF 0.10 from the original par value of CHF 15.00.  The reduction of par value became effective as 
of January 7, 2016, upon registration in the commercial register.  See Note 15—Shareholders’ Equity. 

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 5—Variable 
Interest Entities and Note 14—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  could  be  clearly  distinguished,  operationally  and  for  financial  reporting  purposes,  from  the  rest  of  our 
business.  See Note 3—New Accounting Pronouncements and Note 8—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 certain instances, when we determine that 
collection is not reasonably assured, we recognize revenues associated with the contract when all revenue recognition criteria have been 
met.  In connection with drilling contracts, we may receive revenues for preparation and mobilization of equipment and personnel or for 
capital improvements to rigs.  We defer the revenues earned and incremental costs incurred that are directly related to contract preparation 
and  mobilization  and  recognize  such  revenues  and  costs  over  the  primary  contract  term  of  the  drilling  project  using  the  straight-line 
method.  We recognize, in operating and maintenance costs and expenses, the fees related to contract preparation and mobilization on a 
straight-line basis over the estimated firm period of drilling, which is consistent with the general pace of activity, level of services being 
provided and dayrates being earned over the life of the contract.  For contractual daily rate contracts, we recognize the losses for loss 
contracts  as  such  losses  are  incurred.    We  recognize  the  costs  of  relocating  drilling  units  without  contracts  to  more  promising  market 
sectors as such costs are incurred.  Upon completion of drilling contracts, we recognize in earnings any demobilization fees received and 
expenses  incurred.    We  defer  capital  upgrade  revenues  received  and  recognize  such  revenues  over  the  primary  contract  term  of  the 
drilling project.  We depreciate the actual costs incurred for the capital upgrade on a straight-line basis over the estimated useful life of the 
asset.  We defer the periodic survey and drydock costs incurred in connection with obtaining regulatory certification to operate our rigs and 
well control systems on an ongoing basis, and we recognize such costs over the period until the next survey using the straight-line method. 

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.  To measure 
the  fair  values  of  granted  or  modified  service-based  restricted  share  units,  we  use  the  market  price  of  our  shares  on  the  grant  date  or 
modification date.  To measure the fair values of restricted share units that are subject to performance targets, we use the market price of 
our shares on the measurement date for the projected number of shares expected to be earned at the end of the performance period.  To 
measure the fair values of granted or modified restricted share units that are subject to market factors, we use a Monte Carlo simulation 
model and, in addition to the assumptions applied for the Black-Scholes-Merton option-pricing model, we apply assumptions using a risk 
neutral approach and an average price at the performance start date. 

We recognize share-based compensation expense in the same financial statement line item as cash compensation paid to the 
respective employees or non-employee directors.  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,  2016,  2015  and  2014,  share-based 
compensation expense was $42 million, $64 million and $98 million, respectively.  In the years ended December 31, 2016, 2015 and 2014, 
income tax benefit on share-based compensation expense was $7 million, $11 million and $15 million, respectively.  See Note 16—Share 
Based Compensation Plans. 

Capitalized interest—We capitalize interest costs for qualifying construction and upgrade projects and only capitalize interest 
during periods in which progress for the construction projects continues to be underway.  In the years ended December 31, 2016, 2015 
and 2014, we capitalized interest costs of $176 million, $140 million and $133 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 currency exchange rate gains and losses in other, net.  In the years ended December 31, 2016, 2015 and 2014, we recognized 
a net loss of $2 million, a net gain of less than $1 million and a net gain of $18 million, respectively, related to currency exchange rates. 

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

AR-65 

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

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.  In evaluating our ability to realize deferred tax assets, we consider all available positive and negative evidence, 
including projected future taxable income and the existence of cumulative losses in recent years.  We also record a valuation allowance for 
deferred tax assets resulting from net operating losses incurred during the year in certain jurisdictions and for other deferred tax assets 
where, in our opinion, it is more likely than not that the financial statement benefit of these losses will not be realized.  Additionally, we 
record a valuation allowance for foreign tax credit carryforwards to reflect the possible expiration of these benefits prior to their utilization. 

We maintain liabilities for estimated tax exposures in our jurisdictions of operation, and we recognize the provisions and benefits 
resulting from changes to those liabilities in our income tax expense or benefit along with related interest and penalties.  Tax exposure 
items include potential challenges to permanent establishment positions, intercompany pricing, disposition transactions, and withholding 
tax rates and their applicability.  These tax exposures are resolved primarily through the settlement of audits within these tax jurisdictions 
or  by  judicial  means,  but  can  also  be  affected  by  changes  in  applicable  tax  law  or  other  factors,  which  could  cause  us  to  revise  past 
estimates.  See Note 7—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 under certain bond indentures, as 
required under certain bank credit arrangements, or held in accounts that are subject to restrictions due to legislation, regulation or court 
order.  We classify such restricted cash investment balances in 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,  2016,  the  aggregate  carrying  amount  of  our  restricted  cash  investments  was  $510 million,  of  which  $466 million  and 
$44 million was classified in other current assets and other assets, respectively.  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.  See Note 11—Debt and Note 13—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 
may occasionally require collateral or other security to support customer receivables.  We establish an allowance for doubtful accounts on 
a  case-by-case  basis,  considering  changes  in  the  financial  position  of  a  customer,  when  we  believe  the  required  payment  of  specific 
amounts owed to us is unlikely to occur.  At December 31, 2016 and 2015, the allowance for doubtful accounts was less than $1 million. 

Materials  and  supplies—We  record  materials  and  supplies  at  their  average  cost  less  an  allowance  for  obsolescence.    We 
estimate the allowance for obsolescence based on historical experience and expectations for future use of the materials and supplies.  At 
December 31, 2016 and 2015, the allowance for obsolescence was $153 million and $148 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, 2016 and 2015, the aggregate carrying amount of our assets held for sale, recorded 
in other current assets, was $6 million and $8 million, respectively.  See Note 10—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,  2016,  the  aggregate  carrying  amount  of  our  property  and  equipment  represented 
approximately 78 percent of our total assets. 

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

The estimated original useful lives of our drilling units range from 20 to 35 years, our buildings and improvements range from 
two to  30 years  and  our  machinery  and  equipment  range  from  four to  20 years.    We  reevaluate  the  remaining  useful  lives  and  salvage 
values  of  our  rigs  when  certain  events  occur  that  directly  impact  the  useful  lives  and  salvage  values  of  the  rigs,  including  changes  in 

AR-66 

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

operating condition, functional capability and market and economic factors.  When evaluating the remaining useful lives of rigs, we also 
consider major capital upgrades required to perform certain contracts and the long-term impact of those upgrades on future marketability. 

Long-lived  asset  impairment—We  review  the  carrying  amounts  of  long-lived  assets,  principally  property  and  equipment,  for 
potential  impairment  when  events  occur  or  circumstances  change  that  indicate  that  the  carrying  amount  of  such  assets  may  not  be 
recoverable. 

For assets classified as held and used, we determine recoverability by evaluating the estimated undiscounted future net cash 
flows based on projected dayrates and utilization of the asset group under review.  We consider our asset groups to be ultra-deepwater 
floaters, harsh environment floaters, deepwater floaters, midwater floaters and 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. 

In the year ended December 31, 2016, we determined that the carrying amount of the deepwater floater asset group exceeded 
its fair value, and we recognized a loss of $52 million ($0.14 per diluted share) associated with the impairment of these long-lived assets.  
In the year ended December 31, 2015, we determined that the carrying amount of the deepwater floater asset group and the midwater 
floater asset group each exceeded its fair value, and we recognized a loss of $507 million ($481 million, or $1.31 per diluted share, net of 
tax) and $668 million ($654 million, or $1.78 per diluted share, net of tax) associated with the impairment of the deepwater floater asset 
group and the midwater floater asset group, respectively, including a loss of $52 million associated with construction in progress related to 
the asset groups.  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 6—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.  See Note 6—Impairments. 

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  and  employee  turnover  rates.    Since  our  defined  benefit  plans  have  ceased  accruing  benefits,  certain 
assumptions, including compensation increases and health care cost trend rates no longer apply.  The two most critical assumptions are 
the long-term rate of return on plan assets and the discount rate. 

AR-67 

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

For  the  long-term  rate  of  return,  we  develop  our  assumptions  regarding  the  expected  rate  of  return  on  plan  assets  based  on 
historical experience and projected long-term investment returns, and we weight the assumptions based on each plan’s asset allocation.  
For the discount rate, we base our assumptions on a yield curve approach using Aa-rated corporate bonds and the expected timing of 
future benefit payments.  For the projected compensation trend rate, we consider short-term and long-term compensation expectations for 
participants, including salary increases and performance bonus payments. 

At December 31, 2016 and 2015, our pension and other postretirement benefit plan obligations represented an aggregate liability 
of $375 million and $414 million, respectively, and an aggregate asset of $5 million and $2 million, respectively, representing the funded 
status of the plans.  In the years ended December 31, 2016, 2015 and 2014, net periodic benefit costs were income of $11 million, costs of 
$26 million and costs of $75 million, respectively.  See Note 12—Postemployment Benefit Plans. 

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

Reclassifications—We  have  made  certain  reclassifications  to  prior  period  amounts  to  conform  with  the  current  year’s 
presentation.    These  reclassifications  did  not  have  a  material  effect  on  our  consolidated  statement  of  financial  position,  results  of 
operations or cash flows. 

Note 3—New Accounting Pronouncements 

Recently adopted accounting standards 

Presentation of financial statements—Effective with our annual report for the year ended December 31, 2016, we adopted 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.  Our adoption 
did not have an effect on the disclosures contained in our notes to consolidated financial statements. 

Recently issued accounting standards 

Stock compensation—Effective January 1, 2017, we will adopt the accounting standards update that allows for simplification of 
the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or 
liabilities  and  classification  on  the  statement  of  cash  flows.    The  update,  which  permits  early  adoption,  is  effective  for  annual  periods 
beginning after December 15, 2016 and interim periods within those annual periods.  Our adoption is not expected to have a material effect 
on our consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes to consolidated 
financial statements. 

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, which permits early adoption, 
is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period.  Given 
the interaction with the accounting standards update related to leases, we expect to adopt the updates concurrently, effective January 1, 
2018, and we expect to apply the full retrospective approach to our adoption.  Our adoption, and the ultimate effect on our consolidated 
financial  statements,  will  be  based  on  an  evaluation  of  the  contract-specific  facts  and  circumstances,  and  such  effect  could  introduce 
variability  to  the  timing  of  our  revenue  recognition  relative  to  current  accounting  standards    We  are  evaluating  the  requirements  to 
determine the effect such requirements may have on our consolidated statements of financial position, operations and cash flows and on 
the disclosures contained in our notes to consolidated financial statements. 

Leases—Effective  no  later  than  January 1,  2019,  we  will  adopt  the  accounting  standards  update  that  (a) requires  lessees  to 
recognize a right to use asset and a lease liability for virtually all leases, and (b) updates previous accounting standards for lessors to align 
certain  requirements  with  the  updates  to  lessee  accounting  standards  and  the  revenue  recognition  accounting  standards.    The update, 
which  permits  early  adoption,  is  effective  for  interim  and  annual  periods  beginning  after  December 15,  2018,  including  interim  periods 
within  those  annual  periods.    Under  the  updated  accounting  standards,  we  have  determined  that  our  drilling  contracts  contain  a  lease 
component,  and  our  adoption,  therefore,  will  require  that  we  separately  recognize  revenues  associated  with  the  lease  and  services 
components.  Given the interaction with the accounting standards update related to revenue from contracts with customers, we expect to 
adopt the updates concurrently, effective January 1, 2018, and we expect to apply the modified retrospective approach to our adoption.  
Our adoption, and the ultimate effect on our consolidated financial statements, will be based on an evaluation of the contract-specific facts 
and  circumstances,  and  such  effect  could  introduce  variability  to  the  timing  of  our  revenue  recognition  relative  to  current  accounting

standards.  We are evaluating the requirements to determine the effect such requirements may have on our consolidated statements of 
financial position, operations and cash flows and on the disclosures contained in our notes to consolidated financial statements. 

Income taxes—Effective no later than January 1, 2018, we will adopt the accounting standards update that requires an entity to 
recognize the income tax consequences of an intra entity transfer of an asset other than inventory when the transaction occurs as opposed 
to  deferring  such  recognition  into  future  periods.    The  update,  which  permits  early  adoption,  is  effective  for  annual  reporting  periods 
beginning after December 15, 2017, including interim periods within those annual periods.  We do not expect that our adoption will have a 
material effect on our consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes to 
consolidated financial statements. 

Statement of cash flows—Effective no later than January 1, 2018, we will adopt the accounting standards update that requires 
that  amounts  generally  described  as  restricted  cash  or  restricted  cash  equivalents  be  included  with  cash  and  cash  equivalents  when 
reconciling the  beginning and end of period total amounts presented on the  statement of cash flows.   The update, which permits  early 
adoption, is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods.  We do not 
expect that our adoption will have a material effect on our consolidated statements of cash flows or on the disclosures contained in our 
notes to consolidated financial statements.  

Note 4—Correction of Errors in Previously Reported Consolidated Financial Statements 

In  calculating  our  income  taxes  for  the  year  ended  December 31,  2016,  we  identified  errors  in our  previously  issued  financial 
statements  for  the  interim  and  annual  periods  prior  to  December 31,  2016  related  to  the  measurement  of  deferred  taxes  in  relation  to:  
(a) the remeasurement of certain nonmonetary assets in Norway, (b) the analysis of our U.S. defined benefit pension plans and effect on 
other comprehensive income and (c) the assessment of realizability of our deferred tax assets and the need for valuation allowances.  We 
assessed  the  materiality  of  these  errors  in  accordance  with  the  U.S.  Securities  and  Exchange  Commission  (“SEC”)  Staff  Accounting 
Bulletin  (“SAB”)  No. 99,  Materiality  and  SAB  No. 108,  Considering  the  Effects  of  Prior  Year  Misstatements  when  Quantifying 
Misstatements in Current Year Financial Statements (“SAB 108”), using both the rollover method and the iron curtain method, as defined in 
SAB 108, and concluded the errors, including other adjustments discussed below, were immaterial to prior years but, if corrected in the 
current  year,  would  have  been  material  to  the  current  year.    Under  SAB 108,  such  prior-year  misstatements  which,  if  corrected  in  the 
current year would be material to the current year, must be corrected by adjusting the prior-year financial statements.  Correcting prior-year 
financial statements for such immaterial misstatements does not require previously filed reports to be amended. 

In addition to the adjustments related to the deferred taxes as noted above, we recorded other adjustments related to the years 
ended  December 31,  2015  and 2014  and  the  quarterly  periods in  the  nine months  ended  September 30,  2016  to  correct  for  immaterial 
errors related to revenues, operating and maintenance costs, depreciation expense, losses on impairment and disposal of assets, interest 
income and income taxes.  These other adjustments were not previously recorded in the appropriate periods, as we concluded that they 
were immaterial to our previously issued consolidated financial statements. 

For  the  year  ended  December 31,  2015,  correction  of  these  errors  increased  our  income  from  continuing  operations  by 
$71 million and net income attributable to controlling interest by $74 million.  For the year ended December 31, 2014, correction of these 
errors  decreased  our  loss  from continuing  operations  by  $66 million  and  net  loss  attributable  to  controlling  interest  by  $74 million.    The 
cumulative  effect  of  those  adjustments  reduced  previously  reported  retained  earnings  by  $11 million.    We  also  corrected  our  financial 
statements for each of the interim periods in the years ended December 31, 2016 and 2015 (see Note 22—Quarterly Results).

Note 5—Variable Interest Entities 

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

Transocean Drilling Services Offshore Inc. (“TDSOI”), a consolidated British Virgin Islands company, was also a variable interest 
entity for which we were the primary beneficiary.  In July 2016, we completed the repurchase of the noncontrolling interest in TDSOI, and 
as  a  result,  TDSOI  became  our  wholly  owned  subsidiary  and  has  been  excluded  from  the  above  carrying  amounts.    At  December 31, 
2015, the net carrying amount of TDSOI, after eliminating the effect of intercompany transactions, was $295 million, including assets of 
$298 million and liabilities of $3 million.  See Note 14—Noncontrolling Interest. 

Unconsolidated variable interest entities—We previously held notes receivable, originally issued to us in connection with the 
sale of two drilling units, which represented a variable interest in the issuer.  In the year ended December 31, 2014, we received aggregate 
cash  proceeds  of  $98 million  from  the  issuer  and  recognized  a  gain  of  $7 million,  recorded  in  other  income,  associated  with  the 
prepayment of the notes and liquidation of our variable interest. 

Note 6—Impairments 

Assets held for sale—In the year ended December 31, 2016, we recognized an aggregate loss of $41 million ($39 million, or 
$0.10  per  diluted  share,  net  of  tax),  associated  with  the  impairment  of  the  deepwater  floaters  M.G. Hulme, Jr.  and  Sedco 702  and  the 
midwater  floaters  GSF Rig 140, Sedco 704,  Transocean Driller,  Transocean John Shaw  and  Transocean Winner,  along  with  related  and 
other equipment, which were classified as assets held for sale at the time of impairment. 

In the year ended December 31, 2015, we recognized an aggregate loss of $700 million ($585 million, or $1.60 per diluted share, 
net of tax) associated with the impairment of the ultra-deepwater floaters Deepwater Expedition and GSF Explorer, the deepwater floaters 
Deepwater Navigator,  Discoverer Seven Seas,  GSF Celtic Sea,  Sedco 707  and  Transocean Rather  and 
floaters 
GSF Aleutian Key, GSF Arctic III, GSF Grand Banks, GSF Rig 135, Transocean Amirante and Transocean Legend, along with related  and 
other equipment, which were classified as assets held for sale at the time of impairment. 

the  midwater 

In the year ended December 31, 2014, we recognized an aggregate loss of $268 million ($221 million, or $0.60 per diluted share, 
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 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 or, in the case of GSF Magellan and GSF Monitor, binding 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. 

Assets  held  and  used—During  the  year  ended  December 31,  2016,  we  identified  indicators  that  the  asset  groups  in  our 
contract  drilling  services  reporting  unit  may  not  be  recoverable.    Such  indicators  included  a  reduction  of  projected  dayrates  and  an 
extension to the currently low utilization rates.  As a result of our testing, we determined that the carrying amount of our deepwater floater 
asset group was impaired.  In the year ended December 31, 2016, we recognized a loss of $52 million ($0.14 per diluted share) which had 
no tax effect, associated with the impairment of the deepwater floater asset group.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

During  the  year  ended  December 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,  customer 
suspensions  of  drilling  programs,  early  contract  terminations  and  cancellations  and  low  dayrate  fixtures.    Our  deepwater floater  and 
midwater  floater  asset  groups,  in  particular,  experienced  significant  declines  in  projected  dayrates  and  utilization  caused  by  increased 
competition  and  marginalization  of  some  of  the  less  capable  drilling  units.    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 losses of $507 million ($481 million, or $1.31 per diluted share, net of tax) and $668 million ($654 million, or $1.78 per diluted 
share, net of tax) associated with the impairment of the deepwater floater asset group and the midwater floater asset group, respectively, 
including losses of $41 million and $11 million, respectively, associated with construction in progress for each asset group. 

During  the  year  ended  December 31,  2014,  we  identified  indicators  that  the  asset  groups  in  our  contract  drilling  services 
reporting  unit  may  not  be  recoverable.    Such  indicators  included  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.  As a result of our testing, we determined that the carrying amount of the deepwater floater asset group was impaired.  
In the year ended December 31, 2014, we recognized a loss of $788 million ($693 million, or $1.91 per diluted share, net of tax) associated 
with the impairment of the deepwater floater asset group. 

We  estimated  the  fair  value  of  the  asset  groups  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 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. 

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. 

Note 7—Income Taxes 

Tax  provision  and  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.  For Swiss federal income taxes, qualifying net dividend income and 
net capital gains on the sale of qualifying investments in subsidiaries are exempt.  Consequently, there is not a direct relationship between 
our Swiss earnings before income taxes and our Swiss income tax expense. 

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. 

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

In the years ended December 31, 2016, 2015 and 2014, our effective tax rate was 11.5 percent, 11.9 percent and (5.0) percent, 

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

At  December 31,  2016  and  2015,  our  deferred  tax  assets  included  U.S.  foreign  tax  credit  carryforwards  of  $33 million  and 
$23 million,  respectively,  which  will  expire  between  2017  and  2026.    The  deferred  tax  assets  related  to  our  net  operating  losses  were 
generated in various worldwide tax jurisdictions.  At December 31, 2016, the net operating losses carryforwards, which were generated in 
various  jurisdictions  worldwide,  included  $200 million  that  do  not  expire  and  $183 million  that  will  expire  beginning  2018  and  2036.    At 
December 31, 2015, the net operating losses carryforwards, which were generated in various jurisdictions worldwide, included $170 million 
that  do  not  expire  and  $195  million  that  will  expire  beginning  2018  and  2035.    At  December 31,  2016  and  2015,  due  to  uncertainty  of 
realization,  we  have  recorded  a  valuation  allowance  of  $412 million  and  $380 million,  respectively,  on  net  operating  losses  and  other 
deferred tax assets. 

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.  We consider the earnings of certain of our subsidiaries to be indefinitely reinvested, and 
accordingly, we have not provided for taxes on these unremitted earnings.  If we were to make a distribution from the unremitted earnings 
of these subsidiaries, we would be subject to taxes payable to various jurisdictions.  If our expectations were to change regarding future tax 
consequences,  we  may  be  required  to  record  additional  deferred  taxes  that  could  have  a  material  adverse  effect  on  our  consolidated 
statement of financial position, results of operations or cash flows.  At December 31, 2016, the amount of indefinitely reinvested earnings 
was approximately $2.5 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,  2016,  2015  and  2014,  we  recognized  income  of  $23 million,  $1 million  and  $57 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, 2016, if recognized, $370 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,  2017,  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. 

Norway  tax  investigations  and  trial—Norwegian  civil  tax  authorities  are  challenging  certain  transactions  undertaken  by  our 
subsidiaries in 1999, 2001 and 2002.  At December 31, 2016, the remaining outstanding civil tax assessment was for NOK 412 million, 
equivalent to approximately $48 million, plus interest, related to a 2001 dividend payment.  On June 26, 2014, the Norwegian district court 
in Oslo ruled that our subsidiary was liable for the civil tax assessment but waived all penalties and penalty interest.  On September 12, 
2014, we and the tax authorities each appealed the ruling.  On June 27, 2016, the tax authorities withdrew their appeal of penalties and 
dropped all penalty claims.  We intend to take all other appropriate action to continue to support our position that our Norwegian tax returns 
are materially correct as filed.  Although we are unable to predict the outcome of this matter, we do not expect the effect, if any, to have a 
material adverse effect on our consolidated statement of financial position, results of operations or cash flows.  See Note 23—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 818 million,  equivalent  to 
approximately  $251 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 139 million, equivalent to approximately 
$43 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. 

Note 8—Discontinued Operations 

Standard jackup and swamp barge contract drilling services—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.  In 
November 2012, we completed the sale of 38 drilling units, and we agreed to operate the standard jackups on behalf of the buyer for a 
period of time that extended to January 2015.  In the year ended December 31, 2014, we recognized operating revenues of $166 million, 
operating  costs  and  related  losses  of  $160 million,  resulting  in  a  loss  of  $8 million  ($0.02 per  diluted  share),  net  of  tax  expense  of 
$14 million, associated with our discontinued drilling services operations. 

Drilling  management  services—In  February 2014,  in  connection  with  our  efforts  to  discontinue  non-strategic  operations,  we 
completed the sale of a subsidiary that performed drilling management services in the North Sea.  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.  In May 2015, the buyer made a cash payment of $15 million to repay the borrowings and terminated the 
line of credit.

(a)  Transocean Inc., a 100 percent owned subsidiary of Transocean Ltd., is the issuer of the notes and debentures.  Transocean Ltd. has provided a full 
and  unconditional  guarantee  of  the  notes  and  debentures  and  borrowings  under  an  unsescured  five-year  revolving  credit  facility  (see  “Five-Year 
Revolving  Credit  Facility”).    Transocean Ltd.  has  no  independent  assets  or  operations,  and  following  the  completion  of  certain  restructuring 
transactions  during  the  year  ended  December 31,  2016,  its  other  subsidiaries  not  owned  indirectly  through  Transocean Inc.  were  minor.  
Transocean Inc. has no independent assets and operations, other than those related to its investments in non-guarantor operating companies and 
balances  primarily  pertaining  to  its  cash  and  cash  equivalents  and  debt.    Except  as  discussed  under  “Indentures”  and  “Debt  issuances—
7.75% Senior Secured Notes and 6.25% Senior Secured Notes,”  Transocean Ltd. and Transocean Inc. are not subject to any significant restrictions 
on their ability to obtain funds from their consolidated subsidiaries by dividends, loans or return of capital distributions. 

Scheduled maturities—At December 31, 2016, the scheduled maturities of our debt were as follows (in millions):

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

Indentures—The indentures that govern our debt contain covenants that, among other things, limit our ability to incur certain 
liens on our drilling units without equally and ratably securing the notes, to engage in certain sale and lease back transactions covering any 
of our drilling units, to allow our subsidiaries to incur certain additional debt, or to engage in certain merger, consolidation or reorganization 
transactions  or  to  enter  into  a  scheme  of  arrangement  qualifying  as  an  amalgamation.    Additionally,  the  indentures  that  govern  the 
7.75% Senior  Secured  Notes  due  October 2024  (the  “7.75% Senior  Secured  Notes”)  and  the  6.25% Senior  Secured  Notes  due 
December 2024  (the  “6.25% Senior  Secured  Notes”  and,  together  with  the  7.75% Senior  Secured  Notes,  the  “Senior  Secured  Notes”) 
contain covenants that limit the ability of our subsidiaries that own or operate the collateral rigs to declare or pay dividends and impose a 
maximum collateral rig leverage ratio (“Maximum Collateral Ratio”), represented by each rig’s earnings relative to the debt balance, that 
changes over the terms of the notes.  At December 31, 2016, the Maximum Collateral Ratio under both indentures was 5.75 to 1.00. 

Interest rate adjustments—The interest rates for certain of our notes are subject to adjustment from time to time upon a change 
to our credit rating of our non-credit enhanced senior unsecured long-term debt (“Debt Rating”).  Effective April 15, 2016, as a result of a 
reduction  of  our  Debt  Rating,  the  interest  rates  on  the  2.50% Senior  Notes  due  October 2017  (the  “2.50% Senior  Notes”)  and  the 
3.80% Senior  Notes  due  October 2022  (the  “3.80% Senior  Notes”)  increased  to  3.75 percent  and  5.05 percent,  respectively.    Effective 
June 15, 2016, as a result of a further reduction of our Debt Rating, the interest rates on the 5.05% Senior Notes due December 2016 (the 
“5.05% Senior  Notes”),  the  6.375% Senior  Notes  due  December 2021  (the  “6.375% Senior  Notes”)  and  the  7.35% Senior  Notes  due 
December 2041  increased  to  6.80 percent,  8.125 percent  and  9.10 percent,  respectively.    Effective  October 15,  2016,  as  a  result  of  a 
further reduction of our Debt Rating, the interest rates on the 2.50% Senior Notes and the 3.80% Senior Notes increased to 4.25 percent 
and 5.55 percent, respectively. 

Five-Year Revolving Credit Facility—In June 2014, we entered into an amended and restated bank credit agreement, which 
established  a  $3.0 billion  unsecured  five-year  revolving  credit  facility,  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 Debt Rating, 
or (2) the base rate specified in  the credit agreement plus the Five-Year Revolving Credit Facility Margin, less one percent per annum.  
Throughout  the  term  of  the  Five-Year  Revolving  Credit  Facility,  we  pay  a  facility  fee  on  the  daily  unused  amount  of  the  underlying 
commitment which ranges from 0.15 percent to 0.35 percent based on our Debt Rating.  Effective May 17, 2016, as a result of a reduction 
of our Debt Rating, the Five-Year Revolving Credit Facility Margin increased to 2.0 percent from 1.75 percent and the facility fee increased 
to 0.35 percent from 0.275 percent.  At December 31, 2016, based on our Debt Rating on that date, the Five-Year Revolving Credit Facility 
Margin was 2.0 percent and the facility fee was 0.35 percent.  At December 31, 2016, 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. 

Debt issuances 

9.00% Senior  Notes—On  July 21,  2016,  we  completed  an  offering  of  an  aggregate  principal  amount  of  $1.25 billion  of 
9.00% senior unsecured notes due July 15, 2023 (the “9.00% Senior Notes”), and we received aggregate cash proceeds of $1.21 billion, 
net of initial discount and costs payable by us.  We used the majority of the net proceeds from the debt offering to complete a tender offer 
(see  “Tender  offer”).    The  9.00% Senior  Notes  are  fully  and  unconditionally  guaranteed  by  Transocean Ltd.  and  certain  wholly  owned 
subsidiaries  of  Transocean Inc.    Such  notes  rank  equal  in  right  of  payment  to  all  of  our  existing  and  future  unsecured  unsubordinated 
obligations and rank structurally senior to the extent of the value of the assets of the subsidiaries guaranteeing the notes.  We will pay 
interest  on  the  9.00% Senior  Notes  semiannually  on  January 15  and  July 15  of  each  year,  beginning  on  January 15,  2017.    We  may 
redeem  all  or  a  portion  of  the  9.00% Senior  Notes  at  any  time  prior  to  July 15,  2020  at  a  price  equal  to  100 percent  of  the  aggregate 
principal amount plus a make-whole provision, and on or after July 15, 2020, at specified redemption prices.  The indenture that governs 
the  9.00% Senior  Notes  contains  covenants  that,  among  other  things,  limit  our  ability  to  incur  certain  liens  on  our  drilling  units  without 
equally  and  ratably  securing  the  notes,  engage  in  certain  sale  and  lease-back  transactions  covering  any  of  our  drilling  units,  allow  our 
subsidiaries to incur certain additional debt, and consolidate, merge or enter into a scheme of arrangement qualifying as an amalgamation. 

7.75% Senior  Secured  Notes  and  6.25% Senior  Secured  Notes—On  October 19,  2016,  we  completed  an  offering  of  an 
aggregate principal amount of $600 million of 7.75% Senior Secured Notes, and we received aggregate cash proceeds of $583 million, net 
of  initial  discount  and  costs  payable  by  us.    On  December 8,  2016,  we  completed  an  offering  of  an  aggregate  principal  amount  of 
$625 million of 6.25% Senior Secured Notes, and we received aggregate cash proceeds of $609 million, net of initial discount and costs 
payable by us.   Additionally, we  were required to make total  cash deposits of approximately $103 million into restricted cash accounts, 
including  $61 million  for  principal  and  $42 million  for  interest,  held  by  the  trustee  for  the  Senior Secured  Notes and  recorded  in  current 
assets.    We  will  pay  interest  on  the  7.75% Senior  Secured  Notes  semiannually  on  April 15  and  October 15  of  each  year,  beginning 
April 15,  2017,  and  we  will  pay  interest  on  the  6.25% Senior  Secured  Notes  semiannually  on  June 1  and  December 1  of  each  year 
beginning on June 1, 2017.  Additionally, on each interest payment date, we will be required to redeem, on a pro rata basis, an aggregate

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

principal amount of $30 million and $31 million of the 7.75% Senior Secured Notes and the 6.25% Senior Secured Notes, respectively, at a 
price  equal  to  100 percent  of  the  principal  amount.    We  may  redeem  all  or  a  portion  of  the  7.75% Senior  Secured  Notes  and  the 
6.25% Senior  Secured  Notes  at  any  time  on  or  prior  to  October 15,  2020  and  December 1,  2020,  respectively,  at  a  price  equal  to 
100 percent of the aggregate principal amount plus a make-whole provision.  We will be required to redeem the notes at a price equal to 
100 percent  of  the  aggregate  principal  amount,  without  a  make-whole  provision,  upon  the  occurrence  of  certain  events  related  to  the 
collateral rig and the related drilling contract. 

The  7.75% Senior  Secured  Notes  are  secured  by  the  assets  and  earnings  associated  with  the  ultra-deepwater  floater 
Deepwater Thalassa  and  the  equity  of  the  wholly  owned  subsidiary  that  owns  the  collateral  rig.    The  6.25% Senior  Secured  Notes  are 
secured by the assets and earnings associated with the ultra-deepwater floater Deepwater Proteus and the equity of the subsidiary that 
owns  the  collateral  rig.    The  7.75% Senior  Secured  Notes  and  the  6.25% Senior  Secured  Notes  are  also  fully  and  unconditionally 
guaranteed  by  Transocean Ltd.,  Transocean Inc.  and,  in  each  case,  the  wholly  owned  subsidiary  that  owns  the  collateral  rig.    At 
December 31, 2016, the aggregate carrying amount of Deepwater Thalassa and Deepwater Proteus was $1.7 billion. 

Debt retirement 

Scheduled maturity—On the scheduled maturity date of December 15, 2016, we made a cash payment of $938 million to repay 

the outstanding 5.05% Senior Notes, at a price equal to 100 percent of the aggregate principal amount. 

Tender  offer—On  August 1,  2016,  we  completed  a  tender  offer  (the  “Tender  Offer”)  to  purchase  for  cash  up  to  $1.0 billion 
aggregate principal amount of our 6.50% Senior Notes due November 2020, 6.375% Senior Notes and 3.80% Senior Notes (collectively, 
the “Tendered Notes”), subject to the terms and conditions specified in the related offer to purchase.  In connection with the Tender Offer,

Note 12—Postemployment Benefit Plans 

Defined benefit pension plans and other postretirement employee benefit plans 

Overview—Benefits  under  all  of  our  U.S.  defined  benefit  pension  plans  have  ceased  accruing.    We  maintain  the  respective 
pension  obligations  under  such  plans  until  they  have  been  fully  satisfied.    As  of  December 31,  2016,  we  maintained  three funded  and 
three unfunded  defined  benefit  plans  in  the  U.S.  (the  “U.S.  Plans”).    During  the  year  ended  December 31,  2016,  we  permitted  certain 
participants of one of our funded U.S. Plans to make a one-time election to receive a payment of retirement benefits in the form of either 
(a) a lump sum distribution or (b) an annuity starting October 1, 2016. 

As of December 31, 2016, we maintained one defined benefit plan in the U.K. (the “U.K. Plan”), under which we and the plan 
trustees mutually agreed to cease accruing benefits, effective March 31, 2016.  As of December 31, 2016, we also maintained two 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”).  During the year ended December 31, 2016, we satisfied our obligations 
under  four funded  defined  benefit  plans  in  Norway  and  the  unfunded  defined  benefit  plans  in  Nigeria.    During  the  year  ended 
December 31,  2015,  we  satisfied  our  obligations  under  the  unfunded  defined  benefit  plans  in  Egypt  and  Indonesia.    We  refer  to  the 
U.K. Plan, the Norway Plans and the plans in Nigeria, Egypt and Indonesia, collectively, as the “Non-U.S. Plans.” 

We refer to the U.S. Plans and the Non-U.S. Plans, collectively, as the “Transocean Plans”.  Additionally, we maintain certain 
unfunded  other  postretirement  employee  benefit  plans  (collectively,  the  “OPEB  Plans”),  under  which  benefits  to  eligible  participants 
diminish during a phase-out period ending December 31, 2025.

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

As  of  December 31,  2016  and  2015,  the  weighted-average  target  and  actual  allocations  of  the  investments  for  our  funded

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

Funding  contributions—In  the  years  ended  December 31,  2016,  2015  and  2014,  we  made  an  aggregate  contribution  of 
$49 million, $39 million and $101 million, respectively, to the Transocean Plans and the OPEB Plans using our cash flows from operations.  
In  the  year  ending  December 31,  2017,  we  expect  to  contribute  $11 million  to  the  Transocean Plans,  and  we  expect  to  fund  benefit 
payments of approximately $3 million for the OPEB Plans as costs are incurred. 

Benefit payments—The following were the projected benefits payments (in millions):

At  December 31,  2016,  we  sponsored  four defined  contribution  plans,  including  (1) a  qualified  savings  plan  covering  certain 
employees working in the U.S. (the “U.S. Savings Plan”), (2) a non-qualified supplemental plan covering certain eligible employees working 
in the U.S. (the “U.S. Savings Restoration Plan”), (3) a qualified savings plan covering certain eligible U.K. employees (the “U.K. Savings 
Plan”) and (4) a non-qualified savings plan covering certain employees working outside the U.S. and U.K. (the “Non-U.S. Savings Plan”).  
In the years ended December 31, 2016, 2015 and 2014, we recognized expense of $51 million, $89 million and $84 million, respectively, 
related to our defined contribution plans. 

The U.S. Savings Plan, effective January 1, 2015, provides eligible employees with matching contributions up to 10.0 percent of 
each participant’s base salary and annual bonus based on the participant’s contribution to the plan.  In the year ended December 31, 2014, 
the U.S. Savings Plan provided eligible employees with matching contributions up to 6.0 percent of each participant’s base salary based on 
the participant’s contribution to the plan.  The U.S. Savings Restoration Plan, effective January 1, 2015, provides eligible employees with 
benefits in excess of those allowed under the U.S. Savings Plan. 

The U.K. Savings Plan provides eligible employees with matching contributions between 4.5 percent and 9.5 percent based on 
the participant’s contribution to the plan.  The Non-U.S. Savings Plan, provides eligible employees with (a) matching contributions up to 
6.0 percent of each participant’s base salary based on the participant’s contribution to the plan and (b) contributions between 4.5 percent 
and 6.5 percent of each participant’s base salary and annual bonus based on the participant’s years of eligible service.  In the year ended 
December 31,  2016,  we  amended  the  Non-U.S.  Savings  Plan,  effective  January 1,  2017,  to  provide  eligible  employees  with  matching 
contributions up to 12 percent of each participant’s base salary and annual bonus based on the participant’s contribution and eliminate the 
portion of the contribution that was based on years of service.

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, 2016, 2015 and 2014, our rental expense for all operating leases, including operating leases with terms of 
less than one year, was approximately $45 million, $72 million and $95 million, respectively. 

We also have a capital lease obligation, which is due to expire in August 2029.  The capital lease contract has an implicit interest 
rate of 7.8 percent and requires scheduled monthly payments of $6 million through August 2029, after which we will have the right and 
obligation  to  acquire  the  drillship  from  the  lessor  for  one dollar.    In  the  years  ended  December 31,  2016,  2015  and  2014,  depreciation 
expense associated with Petrobras 10000, the asset held under capital lease, was $23 million, $23 million and $21 million, respectively.  At 
December 31, 2016 and 2015, the aggregate carrying amount of this asset held under capital lease was as follows (in millions):

We have entered into purchase obligations with shipyards and other contractors related to our newbuild construction programs.  
We have also entered into long-term service agreements with original equipment manufacturers to provide services and parts related to 
our  pressure  control  systems.    The  future  payments  required  under  our  service  agreements  were  estimated  based  on  our  projected 
operating activity and may vary based on actual operating activity.  At December 31, 2016, the aggregate future payments required under

Letters of credit and surety bonds 

At December 31, 2016 and 2015, we had outstanding letters of credit totaling $50 million and $153 million, respectively, issued 
under various uncommitted credit lines, some of which require cash collateral, provided by several banks to guarantee various contract 
bidding, performance activities and customs obligations.  At December 31, 2016, the aggregate cash collateral held by banks for letters of 
credit was $5 million.  As is customary in the contract drilling business, we also have various surety bonds in place that secure customs 
obligations related to the importation of our rigs and certain performance and other obligations.  At December 31, 2016 and 2015, we had 
outstanding surety bonds totaling $33 million and $30 million, respectively.

Macondo well incident commitments and contingencies 

Overview—On April 22, 2010, the ultra-deepwater floater Deepwater Horizon sank after a blowout of the Macondo well caused a 
fire and explosion on the rig off the coast of Louisiana.  At the time of the explosion, Deepwater Horizon was contracted to an affiliate of 
BP plc. (together with its affiliates, “BP”).  Following the incident, we have been subject to civil and criminal claims, as well as causes of 
action,  fines  and  penalties  by  local,  state  and  federal  governments.    Litigation  commenced  shortly  after  the  incident,  and  most  claims 
against us were consolidated by the U.S. Judicial Panel on Multidistrict Litigation and transferred to the U.S. District Court for the Eastern 
District of Louisiana (the “MDL Court”).  A significant portion of the contingencies arising from the Macondo well incident has now been 
resolved  as  a  result  of  settlements  with  the  U.S.  Department  of  Justice  (the  “DOJ”),  BP  and  the  states  of  Alabama,  Florida,  Louisiana, 
Mississippi, and Texas (collectively, the “States”).  Additionally, we entered into the PSC Settlement Agreement, which remains subject to 
approval by the MDL Court. 

In the year ended December 31, 2015, in connection with the settlements, as further described below, we recognized income of 
$788 million  ($735 million,  or  $2.02 per  diluted  share,  net  of  tax)  recorded  as  a  net  reduction  to  operating  and  maintenance  costs  and 
expenses, including $538 million associated with recoveries from insurance for our previously incurred losses, $125 million associated with 
partial reimbursement from BP for our previously incurred legal costs, and $125 million associated with a net reduction to certain related 
contingent liabilities, primarily associated with contingencies that have either been settled or otherwise resolved as a result of settlements 
with BP and the PSC. 

We  have  recognized  a  liability  for  the  remaining  estimated  loss  contingencies  associated  with  litigation  resulting  from  the 
Macondo well incident that we believe are probable and for which a reasonable estimate can be made.  At December 31, 2016 and 2015, 
the  liability  for  estimated  loss  contingencies  that  we  believe  are  probable  and  for  which  a  reasonable  estimate  can  be  made  was 
$250 million,  recorded  in  other  current  liabilities.    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.  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. 

Plea  Agreement—Pursuant  to  the  plea  agreement  (the  “Plea  Agreement”),  one of  our  subsidiaries  pled  guilty  to 
one misdemeanor count of negligently discharging oil into the U.S. Gulf of Mexico, in violation of the Clean Water Act (“CWA”) and agreed 
to  be  subject  to  probation  through  February 2018.    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  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 each of the years ended December 31, 2016, 
2015  and  2014,  we  made  an  aggregate  cash  payment  of  $60 million  in  satisfaction  of  amounts  due  under  the  Plea Agreement.    At 
December 31, 2016 and 2015, the carrying amount of our liability for settlement obligations under the Plea Agreement was $60 million and 
$120 million, respectively.  The final installment of $60 million is due on February 14, 2017. 

Consent Decree—Under  the  civil  consent  decree  (the  “Consent Decree”),  we  agreed  to  undertake  certain  actions,  including 
enhanced safety and compliance actions when operating in U.S. waters.  The Consent Decree 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 
approved  on  January 2,  2014,  that  contains,  among  other  things,  interim  milestones  for  actions  in  specified  areas  and  schedules  for 
reports required under the Consent Decree.  Additionally, in compliance with the requirements of the Consent Decree and upon approval 
by  the  DOJ,  we  retained  an  independent  auditor  to  review  and  report  to  the  DOJ  our  compliance  with  the  Consent  Decree  and  an 
independent process safety consultant to review report and assist with the process safety requirements of the Consent Decree.  We may 
request termination of the Consent Decree after January 2, 2019, provided we meet certain conditions.  The Consent Decree resolved the 
claim by the U.S. for civil penalties under the CWA.  The Consent Decree did not resolve the U.S. claim under the Oil Pollution Act (“OPA”) 
for natural resource damages (“NRD”) or for removal costs.  However, BP has agreed to indemnify us for NRD and most removal costs 
(see “—BP Settlement Agreement”).  We also agreed to pay civil penalties of $1.0 billion plus interest.  In the year ended December 31, 
2015, we made a cash payment of $204 million, including interest, representing the final installment due under the Consent Decree. 

BP Settlement  Agreement—On  May 20,  2015,  we  entered  into  a  settlement  agreement  with  BP  (the  “BP Settlement 
Agreement”).    Under  the  BP Settlement  Agreement,  BP  agreed  to  indemnify  us  for  compensatory  damages,  including  all  NRD  and  all 
cleanup  and  removal  costs  for  oil  or  pollutants  originating  from  the  Macondo  well.    BP  also  agreed  to  cease  efforts  to  recover  as  an 
unlimited  additional  insured  under  our  insurance  policies  and  to  be  bound  to  the  insurance  reimbursement  rulings  related  to  the 
Macondo well incident.  We agreed to 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.  Additionally, we mutually agreed to release and withdraw all 
claims  we  have  against  each  other  arising  from  the  Macondo well  litigation  and  to  refrain  from  making  statements  regarding  gross 
negligence in the Macondo well incident.  In July 2015, pursuant to the BP Settlement Agreements, we received $125 million from BP as 
partial  reimbursement  of  the  legal  costs  we  incurred  in  connection  with  the  Macondo well  incident.    We  believe  the  BP Settlement 
AR-87 

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

Agreement  resolved  all  Macondo well-related  litigation  between  BP  and  us,  and  the  indemnity  BP  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. 

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 were given the opportunity to opt out of the PSC Settlement Agreement before September 23, 2016, and 36 claimants 
timely  opted  out,  to  pursue  punitive  damages  claims  against  us.    Six of  these  36 claimants  later  revoked  their  opt  out  requests.    In 
June 2016 and August 2015, we made a cash deposit of $25 million and $212 million, respectively, into escrow accounts pending approval 
of the settlement by the MDL Court.  At December 31, 2016 and 2015, the aggregate balance in escrow was $237 million and $212 million, 
respectively, recorded in other current assets. 

Pending  claims—As  of  December 31,  2016,  numerous  complaints  remain  pending  against  us,  along  with  other  unaffiliated 
defendants 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 opted out of the PSC Settlement 
Agreement, claims by the Mexican government under OPA and maritime law and federal securities actions, we are vigorously defending 
those claims and pursuing any and all defenses available.  See”—PSC Settlement Agreement” and “—Federal securities claims.” 

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  (the  “Second 
Circuit”),  but  on  March  17,  2016,  the  Second  Circuit  affirmed  the  dismissal.    Plaintiffs  filed  a  petition  for  writ  of  certiorari  with  the  U.S. 
Supreme Court on August 12, 2016.  See Note 23—Subsequent Events. 

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 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.  In the year ended December 31, 2016, we recognized income of $30 million, recorded as a 
reduction in operating and maintenance costs and expenses, associated with claims confirmed by certain underwriters, and we received 
cash proceeds of $20 million.  We continue to pursue claims submitted to the Bermuda Insurers, but we cannot give any assurance that we 
will successfully recover additional proceeds under the available policy limits. 

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 in 2014, a group of similar complaints 
were  filed  in  Louisiana.    The  plaintiffs,  former  employees  of  some  of  the  defendants,  generally  allege  that  the  defendants  used  or 
manufactured  asbestos  containing  drilling  mud  additives  for  use  in  connection  with  drilling  operations,  claiming  negligence,  products 
liability,  strict  liability  and  claims  allowed  under  the  Jones  Act  and  general  maritime  law.    The  plaintiffs  generally  seek  awards  of 
unspecified compensatory and punitive damages, but the court appointed special master has ruled that a Jones Act employer defendant, 
such  as  us,  cannot  be  sued  for  punitive  damages.    At  December 31,  2016,  15 plaintiffs  have  claims  pending  in  Mississippi  and 
eight plaintiffs have claims pending in Louisiana in which we have or may have an interest.  We intend to defend these lawsuits vigorously, 
although we can provide no assurance as to the outcome.  We historically have maintained broad liability insurance, although we are not 
certain whether insurance will cover the liabilities, if any, arising out of these claims.  Based on our evaluation of the exposure to date, we 
do not expect the liability, if any, resulting from these claims to have a material adverse effect on our consolidated statement of financial 
position, results of operations or cash flows. 

One of our subsidiaries has been named as a defendant, along with numerous other companies, in lawsuits arising out of the 
subsidiary’s  manufacture  and  sale  of  heat  exchangers,  and  involvement  in  the  construction  and  refurbishment  of  major  industrial 
complexes alleging bodily injury or personal injury as a result of exposure to asbestos.  As of December 31, 2016, the subsidiary was a 

AR-88 

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

defendant  in  approximately  305 lawsuits,  some  of  which  include  multiple  plaintiffs,  and  we  estimate  that  there  are  approximately 
329 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 operating assets of the subsidiary were sold and its operations were discontinued in 1989, and the subsidiary has no 
remaining assets other than insurance policies, rights and proceeds, including (i) certain policies subject to litigation and (ii) certain rights 
and proceeds held directly or indirectly through a qualified settlement fund.  The subsidiary has in excess of $1.0 billion 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 payments from insurers, assigned rights 
from insurers and coverage-in-place settlement agreements with insurers to respond to these claims.  While we cannot predict or provide 
assurance as to the outcome of these matters, we do not expect the ultimate liability, if any, resulting from these claims to have a material 
adverse effect on our consolidated statement of financial position, results of operations or cash flows. 

Rio de Janeiro tax assessment—In the year ended December 31, 2006, the state tax authorities of Rio de Janeiro in Brazil 
issued to one of our subsidiaries tax assessments on equipment imported into the state in connection with our operations, resulting from a 
preliminary  finding  by  these  authorities  that  our  record  keeping  practices  were  deficient.    At  December 31,  2016,  the  aggregate  tax 
assessment was for BRL 506 million, equivalent to approximately $155 million, including interest and penalties.  In September 2006, we 
filed an initial response refuting these tax assessments, and, in September 2007, the state tax authorities confirmed that they believe the 
tax assessments are valid.  On September 27, 2007, we filed an appeal with the state Taxpayer’s Council contesting the assessments.  
While we cannot predict or provide assurance as the final outcome of these proceedings, we do not expect it to have a material adverse 
effect on our condensed consolidated statement of financial position, results of operations or cash flows. 

Nigerian Cabotage Act litigation—In October 2007, three of our subsidiaries were each served a Notice and Demand from the 
Nigeria  Maritime  Administration  and  Safety  Agency,  imposing  a  two percent  surcharge  on  the  value  of  all  contracts  performed by  us  in 
Nigeria pursuant to the Coastal and Inland Shipping (Cabotage) Act 2003 (the “Cabotage Act”).  Our subsidiaries each filed an originating 
summons  in  the  Federal  High  Court  in  Lagos  challenging  the  imposition  of  this  surcharge  on  the  basis  that  the  Cabotage Act  and 
associated levy is not applicable to drilling rigs.  The respondents challenged the competence of the suits on several procedural grounds.  
The court upheld the objections and dismissed the suits.  In December 2010, our subsidiaries filed a new joint Cabotage Act suit.  While 
we cannot predict or provide assurance as to the outcome of these proceedings, we do not expect the proceedings to have a material 
adverse effect on our consolidated statement of financial position, results of operations or cash flows. 

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.  Such matters include a certain Brazilian import 
license  assessment  received  in 2010  related  to  timely  application  for  import  licenses  for  certain  equipment  and  for  allegedly  providing 
improper information on import license applications.  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 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, which  is now a part of the San Gabriel Valley,  Area 3, 
Superfund  site.    We  were  also  advised  that  one or  more  of  our  subsidiaries  that  formerly  owned  and  operated  the  site  would  likely  be 
named  by  the  EPA  as  PRPs.    The  current  property  owner,  an  unrelated  party,  performed  the  required  testing  and  detected  no 
contaminants.  In discussions with CRWQCB staff, we were advised of their intent to issue us a “no further action” letter, but it has not yet 
been received.  Based on the test results, we would contest any potential liability.  We have no knowledge at this time of the potential cost 

AR-89 

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

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.

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 5—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 

Transocean Partners—On  February 6,  2014,  we  formed  Transocean Partners  to  own,  operate  and  acquire  modern, 
technologically advanced offshore drilling rigs.  On August 5, 2014, we completed the initial public offering of 20.1 million common units of 
Transocean Partners.    We  retained  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. 

In the years ended December 31, 2016, 2015 and 2014, Transocean Partners declared and paid an aggregate distribution of, 
$99 million, $100 million and $15 million, respectively, to its unitholders, of which $28 million, $29 million and $4 million, respectively, was 
paid to the holders of noncontrolling interest. 

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.  Under the unit repurchase program, Transocean Partners 
repurchased 478,376 of its publicly held common units for an aggregate purchase price of $4 million and such repurchased common units 
were cancelled. 

On December 9, 2016, Transocean Partners completed a merger with one of our subsidiaries as contemplated under the Merger 
Agreement.  Following the completion of the merger, Transocean Partners became a wholly owned indirect subsidiary of Transocean Ltd.  
Each  Transocean Partners  common  unit  that  was  issued  and  outstanding  immediately  prior  to  the  closing,  other  than  the  units  held  by 
Transocean  and  its  subsidiaries,  was  converted  into  the  right  to  receive  1.20 of  our  shares.    To  complete  the  merger,  we  issued 
23.8 million shares from conditional capital. 

TDSOI—In June 2016, we served notice of our intent to exercise our option to call the 30 percent ownership interest in TDSOI 
held by our local partner.  In July 2016, we completed the repurchase of the noncontrolling interest for a cash payment of $2 million, and as 
a result, TDSOI became our wholly owned subsidiary.  In connection with the transaction, we recorded a capital allocation resulting in a 
$12 million increase to noncontrolling interest and a corresponding decrease to additional paid in capital.

Note 15—Shareholders’ Equity 

Par value reduction—On October 29, 2015, at our extraordinary general meeting, our shareholders approved the reduction of 
the par value of each of our shares to CHF 0.10 from the original par value of CHF 15.00.  The reduction of par value became effective as 
of January 7, 2016 upon registration in the commercial register. 

Distributions  of  qualifying  additional  paid-in  capital—In  May 2015,  at  our  annual  general  meeting,  our  shareholders 
approved the distribution of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $0.60 per outstanding 
share, payable in four quarterly installments of $0.15 per outstanding share, subject to certain limitations.  In May 2015, we recognized a 
liability  of  $218 million  for  the  distribution  payable,  recorded  in  other  current  liabilities,  with  a  corresponding  entry  to  additional  paid-in 
capital.  On June 17 and September 23, 2015, we paid the first two installments in the aggregate amount of $109 million to shareholders of 
record as of May 29 and August 25, 2015.  On October 29, 2015, at our extraordinary general meeting, our shareholders approved the 
cancellation  of  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.  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.    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 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 did not pay the distribution of qualifying additional paid-in capital with respect to our shares held in treasury or held by our 

subsidiary. 

Shares  issued—To  complete  the  merger  with  Transocean Partners,  we  issued  23.8 million  shares  from  conditional  capital.  
Each  Transocean Partners  common  unit  that  was  issued  and  outstanding  immediately  prior  to  the  closing,  other  than  the  units  held  by 
Transocean  and  its  subsidiaries,  was  converted  into  the  right  to  receive  1.20 of  our  shares.    See  Note 1—Business,  Note 14—
Noncontrolling Interest and Note 18—Supplemental Cash Flow Information. 

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  $3.4 billion.    On  February 12,  2010,  our  board  of  directors  authorized  our  management  to 
implement the share repurchase program.  During the three-year period ended December 31, 2016, we did not purchase any shares under 
our share repurchase program.  At December 31, 2015, we held 2.9 million shares in treasury, recorded at cost.  On October 29, 2015, at 
our extraordinary general meeting, our shareholders approved the cancellation of all shares that had 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 in the 
commercial register. 

Shares held by subsidiaries—Two of our subsidiaries hold our shares for future use to satisfy our obligations to deliver shares 
in connection with awards granted under our incentive plans or other rights to acquire our shares.  At December 31, 2016 and 2015, our 
subsidiaries held 5.4 million shares and 6.9 million shares, respectively.

Note 16—Share-Based Compensation Plans 

Overview 

We have a long-term incentive plan (the “Long-Term Incentive Plan”) for executives, key employees and non-employee directors 
under which awards can be granted in the form of restricted share units, restricted shares, stock options, stock appreciation rights and 
cash performance awards.  Awards may be granted as service awards that are earned over a defined service period or as performance 
awards that are earned based on the achievement of certain market factors or performance targets or a combination of market factors and 
performance targets.  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, 2016, we had 55.4 million shares authorized and 14.7 million shares available to 
be granted under the Long-Term Incentive Plan.  As of December 31, 2016, total unrecognized compensation costs related to all unvested 
share-based awards were $43 million, which are expected to be recognized over a weighted-average period of 1.4 years. 

Service awards typically vest either in three equal annual installments beginning on the first anniversary date of the grant or in an 
aggregate  installment  at  the  end  of  the  stated  vesting  period.    Performance  awards  typically  are  subject  to  a  three-year  measurement 
period during which the number of options, 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  and,  thereafter  subject  to  a  stated  vesting  period.    The 
performance  awards  typically  vest  in  one aggregate  installment  following  the  determination  date.    Stock  options  and  stock  appreciation 
rights are subject to a stated vesting period and, once vested, typically have a seven-year term during which they are exercisable. 

Service awards 

Restricted share units—A restricted share 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 units granted 
under our incentive plans during the year ended December 31, 2016:

During the years ended December 31, 2015 and 2014, we granted 2,848,521 and 1,208,790 service-based units, respectively, 
with a weighted-average grant-date fair value of $18.70 and $42.80 per unit, respectively.  During the years ended December 31, 2015 and

During  the  year  ended  December 31,  2016,  we  granted  service-based  stock  options  with  a  weighted-average  grant  date  fair 
value of $8.61 per stock option.  We estimated the fair value using the following weighted-average assumptions: (a) a dividend yield of 
zero percent,  (b) an  expected  price  volatility  of  65 percent,  (c) a risk-free  interest  rate  of  1.26 percent  and  (d) an expected  option  life  of 
6.1 years.  During the year ended December 31, 2016, the aggregate grant-date fair value of service-based stock options that vested was 
$3 million.  During the year ended December 31, 2016, no service-based stock options were exercised.  As of December 31, 2016, there 
were  outstanding  unvested  service-based  stock  options  to  purchase  912,302 shares.    At  January 1,  2016,  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 years ended December 31, 2015 and 2014, we did not grant service-based stock options.  During the years ended 
December 31,  2015  and  2014,  the  total  grant-date  fair  value  of  service-based  stock  options  that  vested  was  $9 million  and  $14 million, 
respectively.    During  the  year  ended  December 31,  2015,  no  service-based  stock  options  were  exercised.    During  the  year  ended 
December 31,  2014,  holders  exercised  service-based  stock  options  to  purchase  383,848 shares,  and  the  total  pre-tax  intrinsic  value  of 
service-based stock options exercised was $2 million. 

Stock appreciation rights—During the years ended December 31, 2016, 2015 and 2014, we did not grant stock appreciation 
rights and no stock appreciation rights were exercised.  At January 1, 2016, there were 185,002 stock appreciation rights outstanding at a 
weighted-average  exercise  price  of  $93.49 per  share  and  less  than  one year  remaining  contractual  life.    At  January 1,  2016  and 
December 31, 2016, the aggregate intrinsic value of such stock appreciation rights was zero since the weighted-average exercise price per 
share exceeded the market price of our shares on that date.  At December 31, 2016, 29,288 stock appreciation rights were vested and 
exercisable, at an exercise price of $107.63 per share with less than one year remaining contractual term. 

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 
for performance-based units under our incentive plans during the year ended December 31, 2016:

During  the  year  ended  December 31,  2016,  performance-based  units  vested  with  an  aggregate  grant-date  fair  value  of 

$6 million, which is subject to compensation committee approval in February 2017. 

During  the  years  ended  December 31,  2015  and  2014,  there  were  652,592  and  302,630 performance-based  units  granted, 
respectively,  with  a  weighted-average  grant-date  fair  value  of  $17.91  and  $31.73 per  unit,  respectively.    During  the  year  ended 
December 31,  2015,  no  performance-based  units  vested  since  neither  the  market  factors  nor  the  performance  targets  were  achieved.  
During the year ended December 31, 2014, the total grant-date fair value of the performance-based units that vested was $8 million. 

Stock options—We previously granted performance awards in the form of stock options that could be earned depending on the 
achievement  of  certain  performance  targets.    During  the  years  ended  December 31,  2016,  2015  and  2014,  we  did  not  grant 
performance-based  stock  options.    At  January 1,  2016,  there  were  150,360 performance-based  stock  options  outstanding  at  a 
weighted-average exercise price of $82.50 per share and less than one year remaining contractual life.  At January 1, 2016, the aggregate 
intrinsic  value  of  such  performance-based  stock  options  was  zero  since  the  weighted-average  exercise  price  per  share  exceeded  the 
market price of our shares on those dates.  During the years ended December 31, 2016 and 2015, no performance-based stock options 
were  exercised.    During  the  year  ended  December 31,  2014,  holders  exercised  performance-based  stock  options  to  purchase 
12,073 shares.  During the year ended December 31, 2016, all remaining performance-based stock options expired.

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, 2016 and 2015, the aggregate carrying amount of our cash equivalents was $2.6 billion and 
$1.7 billion, respectively. 

Restricted  cash  balances  and  investments—The  carrying  amount  of  the  cash  investments  pledged  for  debt  service  of  the 
Eksportfinans  Loans  represents  the  amortized  cost  of  our  investment.    We  measured  the  estimated  fair  value  of  such  restricted  cash 
investments using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit 
spreads of the instruments.  At December 31, 2016 and 2015, the aggregate carrying amount of the cash investments pledged for debt 
service of the Eksportfinans Loans was $123 million and $216 million, respectively.  At December 31, 2016 and 2015, the estimated fair 
value of such restricted cash investments was $124 million and $223 million, respectively. 

The carrying amount of the cash balances that are subject to restrictions due to collateral requirements, legislation, regulation or 
court  order  approximates  fair  value  due  to  the  short  term  nature  of  the  instruments  in  which  the  restricted  cash  balances  are  held.    At 
December 31,  2016,  the  aggregate  carrying  amount  of  such  restricted  cash  balances  was  $387 million,  including  $352 million  and 
$35 million recorded in current assets and other long-term assets, respectively.  At December 31, 2015, the aggregate carrying amount of 
such restricted cash balances was $251 million, including $244 million and $7 million recorded in current assets and other current assets, 
respectively. 

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

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

Note 20—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.  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 or when we repurchase debt in 
open market repurchases.  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. 

Currency  exchange  rate  risk—Our  international  operations  expose  us  to  currency  exchange  rate  risk.    This  risk  is  primarily 
associated with compensation costs of our employees and purchasing costs from non-U.S. suppliers, which are denominated in currencies 
other  than  the  U.S.  dollar.    We  use  a  variety  of  techniques  to  minimize  the  exposure  to  currency  exchange  rate  risk,  including  the 
structuring of customer contract payment terms. 

Our primary currency exchange rate risk management strategy involves structuring customer contracts to provide for payment in 
both  U.S.  dollars  and  local  currency.    The  payment  portion  denominated  in  local  currency  is  based  on  anticipated  local  currency 
requirements  over  the  contract  term.    Due  to  various  factors,  including  customer  acceptance,  local  banking  laws,  national  content 
requirements,  other  statutory  requirements,  local  currency  convertibility  and  the  impact  of  inflation  on  local  costs,  actual  local  currency 
needs  may  vary  from  those  anticipated  in  the  customer  contracts,  resulting  in  partial  exposure  to  currency  exchange  rate  risk.    The 
currency exchange effect resulting from our international operations generally has not had a material impact on our operating results. 

Credit  risk—Financial  instruments  that  potentially  subject  us  to  concentrations  of  credit  risk  are  primarily  cash  and  cash 

equivalents, short-term investments and trade receivables, both current and long-term.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued 

We generally maintain our cash 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 20—Operating  Segments,  Geographic 
Analysis and Major Customers).  We establish an allowance for doubtful accounts on a case-by-case basis, considering changes in the 
financial position of a customer, when we believe the required payment of specific amounts owed to us is unlikely to occur.  Although we 
have encountered only isolated credit concerns related to independent oil companies, we occasionally require collateral or other security to 
support customer receivables.  In certain instances, when we determine that collection is not reasonably assured, we may occasionally 
offer extended payment terms and recognize revenues associated with the contract on a cash basis. 

Labor  agreements—We  require  highly  skilled  personnel  to  operate  our  drilling  units.    We  conduct  extensive  personnel 
recruiting,  training  and  safety  programs.    At  December 31,  2016,  we  had  approximately  5,400 employees,  including  approximately 
400 persons  engaged  through  contract  labor  providers.    Approximately  28 percent  of  our  total  workforce,  working  primarily  in  Angola, 
Brazil,  Norway  and  the  U.K.  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 21—Operating Segments, Geographic Analysis and Major Customers 

Operating segments—We operate in a single, global market for the provision of contract drilling services to our customers.  The 
location of our rigs and the allocation of our resources to build or upgrade rigs are determined by the activities and needs of our customers.

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

10 percent of total long-lived assets. 

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, 2016 and 2015, the 
aggregate carrying amount of our long-lived assets located in Switzerland was $2 million. 

Our international operations are subject to certain political and other uncertainties, including risks of war and civil disturbances or 
other  market  disrupting  events,  expropriation  of  equipment,  repatriation  of  income  or  capital,  taxation  policies,  and  the  general hazards 
associated with certain areas in which we operate.

Norway tax  investigations  and  trial—On  January 9,  2017,  the  Norwegian  appeal  court  in  Oslo  ruled  entirely  in  favor  of  the 
Transocean  subsidiaries  and  overturned  the  district  court  with  respect  to  the  remaining  question  of  principal  tax  obligations.    On 
February 10, 2017, the tax authorities filed an appeal with the Norwegian Supreme Court. 

Federal securities claims—On January 13, 2017, the U.S. Supreme Court granted certiorari in a separate case, not involving 
Transocean,  which  raised  the  same  issues  on  which  the  Second  Circuit  dismissed  the  claim  against  Transocean.    The  U.S.  Supreme 
Court’s ultimate determination of this separate case may affect the time-barred dismissal of the case involving Transocean. 

PSC  Settlement  Agreement—On  February 15,  2017,  the  MDL  Court  entered  a  final  order  and  judgment  approving  the  PSC 
Settlement Agreement that we entered into with the PSC on May 29, 2015.  The ruling is subject to appeal.  Any notice of appeal must be 
filed by March 17, 2017.

Item 9. 

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

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

financial statements or in any period subsequent to such date. 

Item 9A. 

Controls and Procedures 

Disclosure  controls  and  procedures—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 defined in the Exchange Act, Rules 13a-15 and 15d-15, as of the end of the period covered by this report.  Our disclosure 
controls  and  procedures  are  designed  to  provide  reasonable  assurance  that  information  required  to  be  disclosed  in  our  reports  filed  or 
submitted under the Exchange Act is (1) accumulated and communicated to our management, including our Chief Executive Officer and 
our Chief Financial Officer, to allow timely decisions regarding required disclosure and (2) recorded, processed, summarized and reported 
within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms.  Based on that evaluation and as a 
result  of  the  material  weakness  in  internal  control  over  financial  reporting  as  set  forth  below,  our  Chief  Executive  Officer  and  Chief 
Financial Officer concluded that our disclosure controls and procedures were not effective as of December 31, 2016. 

Internal control over financial reporting—In the course of the external audit of the consolidated financial statements for the 
year ended December 31, 2016 and of our related control over financial reporting, errors resulting from the deficient controls described 
below were identified for which correction of the cumulative error would have been material to the 2016 financial statements, but which was 
not material to any of our previously issued consolidated financial statements.  The errors did not result in a material misstatement in our 
prior financial statements and therefore did not require our previously filed reports to be amended.  However, as a result of the significance 
of  the  cumulative  accounting  errors  resulting  from  the  deficient  controls,  the  financial  statements  for  2014  and  2015  and  the  interim 
financial  statements  in  2016  and  2015  have  been  revised.    The  corrections  of  prior  year  financial  statements  for  2014  and  2015  are 
included in the consolidated financial statements for December 31, 2016 that are included in this annual report. 

In connection with the errors, we evaluated the deficiencies in our internal controls over financial reporting and determined our 
internal control over financial reporting as of December 31, 2016 was not effective due to a material weakness in our controls over income 
tax accounting.  Specifically, the execution of the controls over the application of the accounting literature to the measurement of deferred 
taxes did not operate effectively in relation to: (1) the remeasurement of certain nonmonetary assets in Norway, (2) the analysis of our U.S. 
defined benefit pension plans and effect on other comprehensive income and (3) the assessment of the realizability of our deferred tax 
assets, and the need for valuation allowances.  The matters were discovered during the course of the 2016 external audit of the accounts 
and related controls. 

Notwithstanding  the  material  weakness  described  above  and  after  having  performed  additional  procedures,  management  has 
concluded  that  the  consolidated  financial  statements  in  this  annual  report  fairly  present,  in  all  material  respects,  our  financial  position, 
results of operations and cash flows for all periods and dates presented. 

Remediation  efforts  to  address  material  weakness—Management  is  committed  to  the  planning  and  implementation  of 
remediation efforts to address this material weakness.  These remediation efforts, summarized below, which are either implemented or in 
process, are intended to both address the identified material weakness and to enhance our overall financial control environment.  In this 
regard, our initiatives include: 

(cid:131)  Add additional personnel and resources with the appropriate level of tax accounting experience 
(cid:131) 
(cid:131)  Enhance integration and documentation standards within and between tax and other key departments 

Invest in additional technical tax accounting training 

We are in the process of remediating this material weakness by executing upon the above actions.  Management believes the 
foregoing  efforts  will  effectively  remediate  the  material  weakness.    The  actions  that  we  are  taking  are  subject  to  ongoing  senior 
management  review,  as  well  as  Audit  Committee  oversight.    As  we  continue  to  monitor  the  effectiveness  of  our  internal  control  over 
financial  reporting  in  the  area  affected  by  the  material  weakness,  we  will  perform  additional  procedures,  including  the  use  of  manual 
mitigating control procedures where necessary, and will employ any additional resources deemed necessary to provide assurance that our 
financial  statements  continue  to  be  fairly  stated  in  all  material  respects.    As  we  continue  to  evaluate  and  work  to  improve  our  internal 
control  over  financial  reporting,  management  may  execute  additional  measures  to  address  potential  control  deficiencies  or  modify  the 
remediation plan described above.  Management will continue to review and make necessary changes to the overall design of our internal 
controls. 

Changes  in  internal  control  over  financial  reporting—We  have  evaluated  remediation  steps  to  improve  our  internal  controls 
associated with income tax accounting, as described above; however, there were no changes to our internal control over financial reporting 
during the year ended December 31, 2016 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”, included in Item 8 of this annual report.

To the General Meeting of 

Transocean Ltd., Steinhausen 

Zurich, March 6, 2017 

Report of the statutory auditor on the financial statements 

As statutory auditor, we have audited the financial statements of Transocean Ltd., which comprise the statement of operations, 

balance sheet and notes (pages SR-3 to SR-12), for the year ended December 31, 2016. 

Board of Directors’ Responsibility 

The Board of Directors is responsible for the preparation of these 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  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, 2016 comply with Swiss law and the company’s articles 

of incorporation. 

Report on Key Audit Matters based on the circular 1/2015 of the Federal Audit Oversight Authority 

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial 
statements of the current period.  These matters were addressed in the context of our audit of the financial statements as a whole, and in 
forming our opinion thereon, and we do not provide a separate opinion on these matters.  For the matter below, our description of how our 
audit addressed the matter is provided in that context. 

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

SR-1 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Impairment assessment of investments in subsidiaries  
Area of 
emphasis 

Transocean Ltd. evaluates its investments in subsidiaries for impairment annually and records an impairment loss 
when the carrying amount of such assets exceeds the recoverable amount.  The assessment of the existence of 
any indicators of impairment of the carrying amount of investments in subsidiaries is judgmental.  In the event that 
indicators  of  impairment  are  identified,  the  assessment  of  the  recoverable  amounts  is  also  judgmental  and 
requires estimation and the use of subjective assumptions. 

Transocean Ltd.  measures  the  recoverable  amount  of  its  investments  in  subsidiaries  by  applying  a  variety  of 
valuation methods, incorporating a combination of income and market approaches and using projected discounted 
cash flows. 

The  primary  risks  are  identifying  impairment  indicators,  inaccurate  models  being  used  for  the  impairment 
assessment, and that the assumptions to support the value of the investments are inappropriate.  The principal 
consideration for our determination that the impairment assessment of investments in subsidiaries is a key audit 
matter is the subjectivity in the assessment of the recoverable amounts which requires estimation and the use of 
subjective assumptions. 

See note 3 to these financial statements for Transocean Ltd.’s disclosures related to investment in subsidiaries.  

Our audit 
response 

Our audit procedures related to the key audit matter of the impairment assessment of investments in subsidiaries 
included the following procedures: 

We performed inquiries of management about the current market conditions supporting the evaluation of potential 
impairment  indicators,  tested  the  key  assumptions  used,  and  performed  procedures  on  Transocean Ltd.’s 
prospective financial information. 

We involved valuation specialists to assist in the evaluation of  management’s valuation models and impairment 
analyses, specifically in testing key assumptions and prospective financial information. 

We performed procedures to assess the valuation models for evidence of management bias considering contrary 
evidence from third party analyst reports, press releases and fleet status reports published by Transocean Ltd.’s 
competitors. 

Report on other legal requirements 

We confirm that we meet the legal requirements on licensing according to the Auditor Oversight Act (AOA) and independence 

(article 728 CO and article 11 AOA) and that there are no circumstances incompatible with our independence. 

In  accordance  with  article  728a paragraph 1  item 3 CO  and  Swiss  Auditing  Standard 890,  we  confirm  that  an  internal  control 

system exists, which has been designed for the preparation of financial statements according to the instructions of the Board of Directors. 

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

NOTES TO STATUTORY FINANCIAL STATEMENTS 

Note 1—General 

Transocean Ltd. (the “Company”, “we”, “us”, or “our”) is the parent company of Transocean Inc., Transocean Management Ltd., 
and Transocean Management Services GmbH., our wholly owned subsidiaries.  Transocean Ltd. is registered with the commercial register 
in the canton of Zug, and its shares are listed on the New York Stock Exchange (“NYSE”).  Our shares were previously listed on the SIX 
Swiss Exchange (“SIX”).  Effective March 31, 2016, at our request, our shares were delisted from the SIX.  At December 31, 2016 and 
2015, we had six and seven full-time employees, respectively. 

Note 2—Significant Accounting Policies 

Presentation—We  have  prepared  our  unconsolidated  statutory  financial  statements  in  accordance  with  the  accounting 
principles as set out in Art. 957 to Art. 963b, of the Swiss Code of Obligations (the “CO”), which became effective January 1, 2013, and 
required  implementation  for  the  year  ended  December 31,  2015.    Since  we  have  prepared  our  consolidated  financial  statements  in 
accordance with U.S. generally accepted accounting standards, a recognized accounting standard, we have, in accordance with the CO, 
elected to forego presenting the statement of cash flows, the additional disclosures and the management report otherwise required by the 
CO.  Our financial statements may be influenced by the creation and release of excess reserves. 

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.

On May 30, 2016, we sold Transocean Services AS to one of our indirect subsidiaries and, accordingly, it is no longer our direct

Impairments—In the year ended December 31, 2016, as a result of our annual impairment test, we determined that the carrying 
amounts of our investments in subsidiaries were not impaired.  In the year ended December 31, 2015, as a result of our interim impairment 
test as of July 2015 and our annual impairment test as of December 31, 2015, we determined that the carrying amounts of our investments 
in subsidiaries were impaired, and, as a result, we recognized an aggregate loss of CHF 3.3 billion associated with the impairment of our 
investments in Transocean Inc. and Transocean Services AS.

In the year ended December 31, 2016, Transocean Partners Holdings Limited (“TPHL”), our wholly owned indirect subsidiary, 
reacquired  the  publicly  held  common  units  of  Transocean  Partners LLC  (“TPLLC”) which  became  our  indirect,  wholly  owned  subsidiary 
(see Note 4—Shareholders’ Equity).  Accordingly, we no longer consider it to be a principal investment. 

In  the  year  ended  December 31,  2016,  we  formed  Transocean  Holdings 1 Limited,  Transocean  Holdings 2 Limited  and 
Transocean  Holdings 3 Limited.    Together  with  Transocean Ltd.,  these  wholly  owned  subsidiaries  have  fully  and  unconditionally 
guaranteed  the  9.00% Senior  Notes  due 2023  issued  by  Transocean Inc.    Additionally,  we  formed  Transocean  Phoenix 2 Limited  and 
Transocean Proteus Limited in connection with the issuance of two series of senior secured notes.

_____________________________ 
(a)  The statutory capital reserve from capital contribution for shares held by subsidiaries represents the aggregate cost of own shares held indirectly by 
Transocean Ltd. through Transocean Inc.  During the years ended December 31, 2016 and 2015, Transocean Inc. withheld 20,699 and 28,909 own 
shares, respectively, through a broker arrangement and limited to statutory tax in satisfaction of withholding taxes due by our employees upon the 
vesting of equity awards granted under our Long-Term Incentive Plan.  For the years ended December 31, 2016 and 2015, the aggregate value of 
own share transactions was CHF 203 thousand and CHF 475 thousand, respectively.  See Note 5—Own Shares. 

Authorized share capital—In May 2014, at our annual general meeting, our shareholders approved an authorized share capital 
in the amount of CHF 337 million, authorizing the issuance of a maximum of 22.5 million fully paid-in shares with a par value of CHF 15 per 
share  at  any  time  until  May 16,  2016.    On  October 29,  2015,  at  our  extraordinary  general  meeting,  our  shareholders  approved  the 
reduction of the par value of each of our shares to CHF 0.10 from the original par value of CHF 15.  Consequently, the previously approved 
authorized share capital in the amount of CHF 337 million has been reduced to CHF 2 million, authorizing the issuance of a maximum of 
22.2 million fully paid-in shares with a par value of CHF 0.10 per share.  In May 2016, at our annual general meeting, our shareholders 
approved an authorized share capital in the amount of CHF 2.2 million, authorizing the issuance of a maximum of 22.3 million fully paid-in 
shares with a par value of CHF 0.10 per share at any time until May 12, 2018. 

Conditional  share  capital—Our  articles  of  association  provide  for  a  conditional  share  capital  that  permits  us  to  issue  up  to 
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. 

On July 31, 2016, we and TPHL entered into an option agreement, as amended on November 22, 2016, pursuant to which we 
granted TPHL the right to acquire from us a number of our shares in connection with its merger with TPLLC, pursuant to which, the publicly

held  common  units  of  TPLLC  not  owned  by  TPHL  were  exchanged  for  the  right  to  receive  our  shares..    On  December 6,  2016,  TPHL 
exercised its right to receive 23.8 million of our shares, which we issued from our conditional share capital, and paid to us $318 million, as 
required under the option agreement.  Following the completion of the merger, TPHL held 95,830 of our shares. 

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,  at  our  extraordinary  general 
meeting,  our  shareholders  approved  the  cancellation  of  the  third and  fourth installments  of  the  distribution.    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.  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 convened a general meeting of shareholders and proposed 
measures that remediate such capital loss.  On October 29, 2015, at our extraordinary general meeting, our shareholders approved the 
reduction of the par value of each of our shares to CHF 0.10 from the original par value of CHF 15.00 and allocated CHF 3.75 billion of the 
aggregate  par  value  reduction  amount  to  reduce  our  accumulated  net  loss.    Effective  January 7,  2016,  our  qualified  capital  loss  was 
effectively remediated upon establishment of a public deed of compliance for our par value reduction and registration in the commercial 
register.

Share  repurchase  program—In  May 2009,  at  our  annual  general  meeting,  our  shareholders  approved  and  authorized  our 
board  of  directors,  at  its  discretion,  to  repurchase  an  amount  of  our  shares  for  cancellation  with  an  aggregate  purchase  price  of  up  to 
CHF 3.5 billion, equivalent to approximately USD 3.4 billion.  At December 31 2015, we held 2.9 million of our shares, repurchased under 
the share repurchase program, with an aggregate carrying amount of CHF 257 million.  On October 29, 2015, at our extraordinary general 
meeting,  our  shareholders  approved  the  cancellation  of  all  shares  that  had  been  repurchased  under  the  share  repurchase  program.  
Effective January 7, 2016, such shares were cancelled upon registration in the commercial register.  

Shares  held  by  subsidiaries—Transocean Inc.  and  TPHL  hold  our  shares  to  satisfy  our  obligations  to  deliver  shares  in 
connection with awards granted under our incentive plans or other rights to acquire our shares.  In the year ended December 31, 2016 and 
2015,  we  transferred  1.6 million  and  1.8 million  shares,  respectively,  at  historical  cost,  from  the  own  shares  held  by  Transocean Inc.  to 
satisfy  obligations  under  our  share-based  compensation  plans.    In  the  years  ended  December 31,  2016  and  2015,  we  received  cash 
proceeds of less than CHF 1 million, in connection with own shares transferred in exchange for equity awards exercised or withheld for 
taxes under our share-based compensation plans.

Transocean 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, 2016 and 2015, the 
aggregate  carrying  amount  of  debt  that  we  have  guaranteed  was  USD 7.5 billion  and  USD 7.4 billion,  respectively,  equivalent  to 
approximately CHF 7.6 billion and CHF 7.3 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, 
2016 and 2015, we recognized guarantee fee income of CHF 2 million and CHF 3 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 compliance obligations required of the Respondents under the EPA Agreement. 

Norway  tax  investigations  and  trial  contingent  obligations—Norwegian  civil  tax  authorities  are  challenging  certain 
transactions  undertaken  by  our  subsidiaries  in  1999,  2001  and  2002.    In  January 2016,  the  Norwegian  authorities  formally  and 
unconditionally dropped their appeals against the Oslo district court acquittals with respect to all criminal charges against our subsidiaries 
and external advisors related to the previously reported Norway tax investigations and trials.  All subsidiaries and external advisors have 
been fully and unconditionally acquitted on all criminal charges. 

At December 31, 2016, the remaining outstanding civil tax assessment was for NOK 412 million, equivalent to approximately 
CHF49 million, plus interest, related to a 2001 dividend payment.  On June 26, 2014, the Norwegian district court in Oslo ruled that our 
subsidiary was liable for the civil tax assessment but waived all penalties and interest.  On September 12, 2014, we and the tax authorities 
each appealed the ruling.  On June 27, 2016, the tax authorities withdrew their appeal of penalties and dropped all penalty claims.  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 prior years, we guaranteed these tax assessments and related contingent obligations.  As of December 31, 2016, all guarantees have 
expired or have been cancelled.  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,  2016  and  2015,  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 our indirect wholly owned subsidiaries (the “Macondo Subsidiaries”), sank after a blowout of the U.S. Gulf of 
Mexico Macondo well caused a fire and explosion on the rig off the coast of Louisiana.  The Macondo Subsidiaries have been named in 
lawsuits  related  to  the  Macondo well  incident.    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  (the  “Second  Circuit”),  but  on  March 17,  2016,  the  Second  Circuit  affirmed  the  dismissal. 
Plaintiffs filed a petition for writ of certiorari with the U.S. Supreme Court on August 12, 2016.  See Note 10—Subsequent Events. 

Swiss value added tax—We are one of a group of Swiss entities, which are jointly and severally liable for the whole Swiss value 

added tax amount due to the Swiss tax authorities by this group. 

Note 9—Related Party Transactions 

Transocean Inc. and Transocean Partners Holdings Limited—Transocean Inc. and TPHL hold our shares to satisfy, on our 
behalf, our obligation to deliver shares in connection with awards granted under our incentive plans, warrants or other right to acquire our 
shares.  At December 31, 2016 and 2015, Transocean Inc. and TPHL held 5.4 million and 6.9 million of our shares, respectively. 

We  and  Transocean Inc.,  as  the  borrower  and  lender,  respectively,  entered  into  a  credit  agreement  dated  June 1,  2011, 
establishing  a  USD 2.0 billion  revolving  credit  facility.    At  December 31,  2016  and  2015,  we  had  borrowings  of  USD 7.2 million  and 
USD 406 million,  respectively,  equivalent  to  approximately  CHF 7.3  million  and  CHF 402 million,  respectively,  outstanding  under  the 
revolving credit facility.  At December 31, 2016 and 2015, the variable interest rate on the outstanding borrowings was 2.25 percent. 

Other  subsidiaries—Our  subsidiaries  perform  on  our  behalf  certain  general  and  administrative  services,  including  executive 
administration,  procurement  and  payables,  treasury  and  cash  management,  personnel  and  payroll,  accounting  and  other  administrative 
functions.    In  the  years  ended  December 31,  2016  and  2015,  we  recognized  such  costs  of  CHF 15 million  and  CHF 19 million, 
respectively, recorded in general and administrative costs and expenses. 

Note 10—Subsequent Events 

Norway tax  investigations  and  trial—On  January 9,  2017,  the  Norwegian  appeal  court  in  Oslo  ruled  entirely  in  favor  of  the 
Transocean  subsidiaries  and  overturned  the  district  court  with  respect  to  the  remaining  question  of  principal  tax  obligations.    On 
February 10, 2017, the tax authorities filed an appeal with the Norwegian Supreme Court. 

Federal securities claims—On January 13, 2017, the U.S. Supreme Court granted certiorari in a separate case, not involving 
Transocean,  which  raised  the  same  issues  on  which  the  Second  Circuit  dismissed  the  claim  against  Transocean.    The  U.S.  Supreme 
Court’s ultimate determination of this separate case may affect the time-barred dismissal of the case involving Transocean. 

PSC  Settlement  Agreement—On  February 15,  2017,  the  MDL  Court  entered  a  final  order  and  judgment  approving  the  PSC 
Settlement Agreement that we entered into with the PSC on May 29, 2015.  The ruling is subject to appeal.  Any notice of appeal must be 
filed by March 17, 2017.

PROPOSED APPROPRIATION OF THE ACCUMULATED LOSS 

The  board  of  directors  proposes  that  shareholders  at  the  annual  general  meeting  in 2017  approve  the  following  appropriation 

(in thousands):

Balance to be carried forward on this account 

  CHF

(4,997,032 )  CHF 

(8,682,993) 

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 2017 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 the following: (a) a reduction of the par 
value  of  each  share  of  the  Company  from  CHF 15  to  CHF 0.10,  (b) 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  (c) 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.  Accordingly, the CHF 3.75 billion reduction of our accumulated loss was 
not reflected in the accumulated loss as of December 31, 2015.  The total accumulated loss as of December 31, 2016, reflects the loss that 
was carried forward from previous years, the reduction of par value and the net loss for the year ended December 31, 2016. 

The Board of Directors proposes that the entire accumulated loss of CHF 4,997,032 be carried forward.
