PART I

Item 1.Business1.Business

Overview

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” the “Company,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells.  As of February 11, 2019,16, 2021, we owned or had partial ownership interests in and operated a fleet of 4937 mobile offshore drilling units, consisting of 31 ultra‑deepwater floaters, 14 harsh environment27 ultra-deepwater floaters and four midwater10 harsh environment floaters.  As of February 11, 2019,16, 2021, we were constructing (i) four additional ultra‑deepwater drillships and (ii) one additional harsh environment semisubmersible, in which we hold a partial ownership interest.two ultra-deepwater drillships.

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

Transocean Ltd. is a Swiss corporation with its registered office in Steinhausen, Canton of Zug and with principal executive offices located at Turmstrasse 30, 6312 Zug,Steinhausen, Switzerland.  Our telephone number at that address is +41 41 749‑0500.749-0500.  Our shares are listed on the New York Stock Exchange under the ticker symbol “RIG.”  For information about the revenues, operating income, assets and other information related to our business, our segments and the geographic areas in which we operate, see “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Part II. Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—Note 20—Operating Segments, Geographic Analysis and Major Customers.”

Recent Developments

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

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

See “Part II. Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—Note 4—Business Combinations.”

Drilling Fleet

Fleet overviewOverview—Our drilling fleet of floaters consists of drillships and semisubmersibles, which are mobile and can be moved to new locations in response to customer demand.  Our drilling equipment is suitable for both exploration and development, and we engage in both types of drilling activity.  Our mobile offshore drilling units are designed to operate in locations away from port for extended periods of time and have living quarters for the crews, a helicopter landing deck and storage space for drill pipe, riser and drilling supplies.

Drillships are generally self‑propelledself-propelled vessels, shaped like conventional ships, and are the most mobile of the major rig types.  Our high‑specificationhigh-specification drillships are equipped with dynamic positioning thruster systems, which allows them to maintain position without anchors through the use of onboard propulsion and station‑keepingstation-keeping systems.  Ultra‑deepwaterUltra-deepwater drillships typically have greater deck load and storage capacity than early generation semisubmersible rigs, which provides logistical and resupply efficiency benefits for customers.  Drillships are generally better suited to operations in calmer sea conditions and typically do not operate in areas considered to be harsh environments.  We have 25 ultra‑deepwater22 ultra-deepwater drillships that are, and four ultra‑deepwatertwo ultra-deepwater drillships under construction that will be, equipped with our patented dual‑activitydual-activity technology.  Dual‑activityDual-activity technology employs structures, equipment and techniques using two drilling stations within a dual derrick to allow these drillships to perform simultaneous drilling tasks in a parallel, rather than a sequential manner, which reduces critical path activity and improves efficiency in both exploration and development drilling.  In addition to dynamic positioning thruster systems, dual‑activitydual-activity technology and industry‑leadingindustry-leading hoisting capacity, one of our contracted newbuild drillshipsdrillship under construction which was recently contracted, will be equipped with and another newbuild drillship will be equipped to accommodate two 20,000 pounds per square inch (“psi”) blowout preventers.

preventers and, if the relevant conditions are satisfied, our newbuild drillship with a conditional agreement will be equipped with one 20,000 psi blowout preventer as required by the conditional agreement and will be equipped to accommodate a second 20,000 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.  Semisubmersibles are known for stability, making them well suited for operating in rough sea conditions.  Semisubmersible floaters are capable of maintaining their position over a well either through dynamic positioning or the use of mooring systems.  Although most semisubmersible rigs are relocated with the assistance of tugs, some units are self‑propelledself-propelled and move between locations under their own power when afloat on pontoons.  FiveFour of our 2213 semisubmersibles are equipped with dual‑activitydual-activity technology and also have mooring capability.  Two of these fivefour dual-activity units are custom‑designed,custom-designed, high capacity semisubmersible drilling rigs, equipped for year‑roundyear-round operations in harsh environments, including those of the Norwegian continental shelf and sub‑Arcticsub-Arctic waters.

Fleet categories—We further categorize the drilling units of our fleet as follows: (1) “ultra‑deepwater floaters,”“ultra-deepwater floaters” and (2) “harsh environment floaters” and (3) “midwater floaters”.  Ultra‑deepwaterfloaters.”  Ultra-deepwater floaters are equipped with high‑pressurehigh-pressure mud pumps and are capable of drilling in water depths of 4,500 feet or greater.  Harsh environment floaters are capable of drilling in harsh environments in water depths between 1,500 and 10,000 feet and have greater displacement, which offers larger variable load capacity, more useable deck space and better motion characteristics.  Midwater floaters are generally comprised of those non‑high‑specification semisubmersibles that have a water depth capacity of less than 4,500 feet.

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

§

31 ultra‑deepwater floaters;

§

14 harsh environment floaters; and

§

Four midwater floaters.

Fleet status—Depending on market conditions, we may idle or stack non‑contractedour non-contracted rigs.  An idle rig is between drilling contracts, readily available for operations, and operating costs are typically at or near normal operating levels.  A stacked rig typically has reduced operating costs, is staffed by a reduced crew or has no crew and is (a) preparing for an extended period of inactivity, (b) expected to continue to be inactive for an extended period, or (c) completing a period of extended inactivity.  Stacked rigs will continue to incur operating

costs at or above normal operating levels for approximately 30 days following initiation of stacking.  Some idle rigs and all stacked rigs require additional costs to return to service.  The actual cost to return to service, which in many instances could be significant and could fluctuate over time, depends upon various factors, including the availability and cost of shipyard facilities, the cost of equipment and materials, and the extent of repairs and maintenance that may ultimately be required.required and time and cost of assembling and training crew.  We consider these factors, together with market conditions, length of contract, dayrate and other contract terms, when deciding whether to return a stacked rig to service.  We may not return some stacked rigs to work for drilling services.

Drilling units—The following tables, presented as of February 11, 2019,12, 2021, 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‑onfollow-on contract.  The dates provided represent the expected time of completion, the year placed into service, and, if applicable, the year of the most recent upgrade.  As of February 11, 2019,12, 2021, we owned all of the drilling rigs in our fleet noted in the tables below, except for the following: (1) the harsh environment floater Transocean Norge, which is under construction and owned through our 33.0 percent ownership interest in Orion Holdings (Cayman) Limited (together with its subsidiary, “Orion”), and (2) the ultra‑deepwaterultra-deepwater floater Petrobras 10000, which is subject to a capitalfinance lease through August 2029.

Markets

Our operations are geographically dispersed in oil and gas exploration and development areas throughout the world.  We operate in a single, global offshore drilling market, as our drilling rigs are mobile assets and are able to be moved according to prevailing market conditions.  We may mobilize our drilling rigs between regions for a variety of reasons, including to respond to customer contracting requirements or to capture demand in another locale.  Consequently, we cannot predict the percentage of our revenues that will be derived from particular geographic areas in future periods.  As of February 11, 2019, our drilling fleet, including stacked and idle rigs, but excluding rigs under construction, was located in the Norwegian North Sea (nine units), the United States (“U.S.”) Gulf of Mexico (seven units), Trinidad (six units), Greece (five units), United Kingdom (“U.K.”) North Sea (five units), Angola (two units), Canada (two units), India (two units), Spain (two units), Australia (one unit), Brazil (one unit), Brunei (one unit), China (one unit), Equatorial Guinea (one unit), Ivory Coast (one unit), Malaysia (one unit), Mexican Gulf of Mexico (one unit) and Romania (one unit).

We categorize the market sectors in which we operate as follows: (1) ultra-deepwater and deepwater, (2) harsh environment and (3) midwater.  These market sectors, collectively known as the floater market, are serviced by our drillships and semisubmersibles, 14 of which are suited to work in harsh environments.  We generally view the ultra-deepwater and deepwater market sector as water depths beginning at 4,500 feet and extending to the maximum water depths in which rigs are capable of drilling, which is currently up to 12,000 feet.  The midwater market sector services water depths from approximately 300 feet to approximately 4,500 feet.  The harsh environment market sector services regions that are more challenged by lower temperatures, harsher weather conditions and water currents.

The market for offshore drilling rigs and related services reflects oil companies’ demand for equipment for drilling exploration, appraisal and development wells and for performing maintenance on existing production wells.    Activity levels of exploration and production (“E&P”) companies and their associated capital expenditures are largely driven by the worldwide demand for energy, including crude oil and natural gas.  Worldwide energy supply and demand drives oil and natural gas prices, which, in turn, impact E&P companies’ ability to fund investments in exploration, development and production activities.

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

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

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

Contract Drilling ServicesContracts

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

-  5  -


zero rate for periods of mobilization or when drilling operations are interrupted or restricted by equipment breakdowns, adverse environmental conditions or other conditions beyond our control.  A dayrate drilling contract generally extends over a period of time either covering either the drilling of a single well or group of wells or covering a stated term.  At December 31, 2018,2020, our contract backlog was approximately $12.5$8.1 billion, representing an increasea decrease of 3222 percent and sevena decrease of 35 percent, respectively, compared to the contract backlog at December 31, 20172019 and 2016,2018, which was $9.5$10.4 billion and $11.7$12.5 billion, respectively.  See “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Performance and Other Key Indicators.”

Certain of our drilling contracts may be cancelable for the convenience of the customer, upontypically with the 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,non-performance, in the event of extended downtime or impaired performance caused bydue to 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.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 early terminate or repudiate their contracts.  Suspension of drilling contracts will result in the reduction in or loss of dayrate for the period of the suspension.  If our customers cancel some of our contracts and we are unable to secure new contracts on a timely basis and on substantially similar terms, if contracts are suspended for an extended period of time or if a number of our contracts are renegotiated, it could adversely affect our consolidated financial position, results of operations or cash flows.  See “Item 1A. Risk Factors—Risks related to our business—Our drilling contracts may be terminated due to a number of events, and, during depressed market conditions, our customers may seek to repudiate or renegotiate their contracts.”

Under dayrate drilling contracts, consistent with standard industry practice, our customers, as the operators, generally assume, and grant indemnity for, subsurface and well control risks, and their consequential damages.  Under all of our current drilling contracts, our customers, indemnify us for pollution damages in connection with reservoir fluids stemming from operations under the contract, and we indemnify our customers for pollution that originates above the surface of the water from the rig from substances in our control, such as diesel used onboard the rig or other fluids stored onboard the rig.  Also, our customers indemnify us for consequential damages they incur, damage to the well or reservoir, loss of subsurface oil and gas and the cost of bringing the well under control.  However, our drilling contracts are individually negotiated, and the degree of indemnification we receive from our customers for the risks discussed above may vary from contract to contract, based on market conditions and customer requirements existing when the contract was negotiated.  In some instances, we have contractually agreed upon certain limits to our indemnification rights and can be responsible for damages up to a specified maximum dollar amount.  The nature of our liability and the prevailing market conditions, among other factors, can influence such contractual terms.  In most instances in which we are indemnified for damages to the well, we have the responsibility to redrill the well at a reduced dayrate.  Notwithstanding a contractual indemnity from a customer, there can be no assurance that our customers will be financially able to indemnify us or will otherwise honor their contractual indemnity obligations.  See “Item 1A. Risk Factors—Risks related to our business—Our business involves numerous operating hazards, and our insurance and indemnities from our customers may not be adequate to cover potential losses from our operations.”

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

Markets

Significant Our operations are geographically dispersed in oil and gas exploration and development areas throughout the world.  We operate in a single, global offshore drilling market, as our drilling rigs are mobile assets and can be moved according to prevailing market conditions.  We may mobilize our drilling rigs between regions for a variety of reasons, including to respond to customer contracting requirements or to capture observed market demand.  Consequently, we cannot predict the future percentage of our revenues that will be derived from particular geographic areas.  As of February 12, 2021, our drilling fleet, including stacked and idle rigs, but excluding rigs under construction, was located in Greece (eight units), the Norwegian North Sea (seven units), the U.S. Gulf of Mexico (seven units), Brazil (three units), Malaysia (three units), the United Kingdom (the “U.K.”) North Sea (two units), Trinidad (two unit), Angola (one unit), Canada (one unit), India (one unit), Myanmar (one unit), and Namibia (one unit).

We categorize the market sectors in which we operate as follows: (1) ultra-deepwater and deepwater, (2) harsh environment, and (3) midwater.  We offer our drilling services across all of these market sectors, collectively known as the floater market, with our drillships and semisubmersibles, 11 of which are suited to work in harsh environments.  We generally view the ultra-deepwater and deepwater market sector as water depths beginning at 4,500 feet and extending to the maximum water depths in which rigs are capable of drilling, which is currently up to 12,000 feet.  The midwater market sector includes water depths from approximately 300 feet to approximately 4,500 feet.  The harsh environment market sector includes regions that are more challenged by lower temperatures, harsher weather conditions and water currents.

Since 2014, the industry has experienced a severe cyclical downturn of considerably longer duration than those previously observed.  Multiple years of volatile and generally weak commodity prices, exacerbated in 2020 by the effects of the COVID-19 pandemic and production disputes among major oil producing countries, have resulted in our customers repeatedly delaying offshore investment decisions and postponing exploration and development programs.  Some of our customers have also recently committed to invest or increase investment in low carbon and renewable energy resources, potentially reducing their expenditures in the development and production of hydrocarbons over the coming decades.  However, even in the context of some diversion of investment away from traditional sources of energy, the structural efficiency gains achieved by the offshore oil and gas segment in the past six years have materially improved the economics of deepwater offshore development projects, making the segment a competitive source of new supply.

We anticipate that the subdued level of contract activity will continue for at least the first half of 2021, although we believe that by the second half of 2021, our customers will again focus on favorable deepwater offshore economics and begin increasing their exploration, production and reserve replacement activities by restarting delayed projects and commencing new campaigns.  This depends on many variables, including global amelioration of the COVID-19 pandemic and the effects of actions by some governments and regulators intended to curtail existing and future drilling activities, and other factors.

Our overall outlook for the offshore drilling sector remains positive, particularly for high-specification assets.  Brazil, the U.S. Gulf of Mexico, and to a lesser extent, West Africa remain key ultra-deepwater market sectors, while Norway represents the largest harsh environment market.  In addition, in 2020, we saw continued strong tendering activity for Asia and Australia.  Licensing activity also indicated an increased interest in these areas as energy companies looked to explore and develop new prospects.

As the economics of offshore development projects have materially improved, we expect deepwater oil and gas production will continue to be a significant part of the long-term strategy for energy companies as they strive to replace reserves to meet global demand for energy sources and hydrocarbons.  .  These projects are technically demanding due to factors such as water depth, complex well designs, deeper drilling depth, high pressure and temperature, sub-salt geological formations, harsh environments, and heightened regulatory standards; therefore, they require high-specification drilling units.

Generally, high-specification rigs are the most modern, technologically advanced class of the offshore fleet and have capabilities that are attractive to energy companies operating in deeper water depths, other challenging environments or with complex well designs.  We have led the industry and made concerted efforts since the beginning of the prolonged downturn to high-grade our fleet profile by acquiring high-specification assets and disposing of lower-specification assets.  In the year ended December 31, 2018, we significantly enhanced our high-specification asset portfolio with our acquisitions of (i) Songa Offshore SE, (ii) Ocean Rig UDW Inc. and (iii) a 33.0 percent ownership interest in Orion.  During the years ended December 31, 2020, 2019 and 2018, we sold for scrap value six, eleven and eight lower-specification drilling units, respectively.

Ultimately, as the hydrocarbon supply-demand balance improves, including as the result of a post-pandemic global economic recovery, we expect a sustained improvement of oil prices, which will result in greater demand for our high-specification fleet of assets, resulting in further improvement of dayrates.  Consequently, when considering the reduced supply of offshore drilling units and expected increase in demand, we expect dayrates for our services should steadily increase over the next several years.  See “Item 1A. Risk Factors—Risks related to our business.”

Risks related to our business

§

Our business depends on the level of activity in the offshore oil and gas industry, which is significantly affected by volatile oil and gas prices and other factors.

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

§

worldwide demand for oil and gas, including economic activity in the U.S. and other large energy‑consuming markets;

energy-consuming markets, which has been significantly impacted by the COVID-19 pandemic and the governmental, company and individual reactions thereto;

§

the ability of the Organization of the Petroleum Exporting Countries (“OPEC”) to set and maintain production levels, productive spare capacity and pricing;

§

the level of production in non‑OPECnon-OPEC countries;

§

inventory levels, and the cost and availability of storage and transportation of oil, gas and their related products;

the policies, laws and regulations of various governments regarding exploration and development of their oil and gas reserves;

reserves, the environment and climate change;

§

international sanctions on oil‑producingoil-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;

§

reserves and the rate of decline of existing oil and gas reserves;

crises.

Demand for our services is particularly sensitive to the level of exploration, development and production activity of, and the corresponding capital spending by, oil and natural gas companies, including national oil companies.  Prolonged reductions in oil and natural gas prices could depress the immediate levels of exploration, development and production activity.  Perceptions of longer‑termlonger-term lower oil and natural gas prices by oil and gas companies could similarly reduce or defer major expenditures given the long‑termlong-term nature of many large‑scalelarge-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‑termnear-term commodity prices do not necessarily translate into increased offshore drilling activity since customers’ expectations of longer‑termlonger-term future commodity prices typically have a greater impact on demand for our rigs.  Consistent with this dynamic, customers may delay or cancel many exploration and development programs, resulting in reduced demand for our services.  Also, increased competition for customers’ drilling budgets could come from, among other areas, land‑basedland-based energy markets worldwide.  The availability of quality drilling prospects, exploration success, relative production costs, the stage of reservoir development and political and regulatory environments also affect customers’ drilling campaigns.  Worldwide military, political and economic events have often contributed to oil and gas price volatility and are likely to do so in the future.

§

The offshore drilling industry is highly competitive and cyclical, with intense price competition.

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

The offshore drilling industry is highly cyclical and is impacted by oil and natural gas price levels and volatility.  Periods of high customer demand, limited rig supply and high dayrates have been followed by periods of low customer demand, excess rig supply and low dayrates.  Changes in commodity prices can have a dramatic effect on rig demand, and periods of excess rig supply may intensify competition in the industry and result in the idling of older and less technologically advanced equipment.  We have idled and stacked rigs,

-  8  -


and may in the future idle or stack additional rigs or enter into lower dayrate drilling contracts in response to market conditions.  Idled or stacked rigs may remain out of service for extended periods of time.  During prior periods of high dayrates and rig utilization rates, we and other industry participants have responded to increased customer demand by increasing the supply of rigs through ordering the construction of new units.  The number of new units expected to be delivered without contracts, combined with the expected increase in thean increased number of rigs in the global market completing contracts and becoming idle, has intensifiedincreased and may furthercontinue to intensify price competition.  In periods of low oil and natural gas price levels, new construction has historically resulted in an oversupply of rigs and has caused a subsequent decline in dayrates and rig utilization rates, sometimes for extended periods of time.  Any further near‑term increase in the construction of new units would likely exacerbate the negative impact of increased supply on dayrates and rig utilization rates.  Additional rigs that remain under construction, and the entry into service of these new units will increase overall supply.  In an oversupplied market, we may have limited bargaining power to negotiate on more favorable terms.  Additionally, lower market dayrates and intense price competition may drive customers to seek to renegotiate existing contracts to lower dayrates in exchange for longer contract terms.  Lower dayrates and rig utilization rates could adversely affect our revenues and profitability.

As of February 11, 2019,12, 2021, we have 1916 uncontracted rigs, including seven uncontracted rigs recently acquired in the Ocean Rig acquisition.  Theseand these rigs may remain out of service for extended periods of time.  We also have threetwo additional rigs under construction, and while both have secured contracts, one has a contract that have not been contracted for work.is conditional upon a final investment decision of the customer and its partners.  If we are unable to obtain drilling contracts for our uncontracted rigs, whether due to a prolonged offshore drilling market downturn, a delayed or muted recovery of such market or otherwise, it may have an adverse effect on our results of operations and cash flows, and weflows.

Our current backlog of contract drilling revenues may not be able to realize the expected synergies and other benefits of the acquisition on the timeline currently expected or at all.

§

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

At February 11, 2019,12, 2021, our contract backlog was approximately $12.2$7.8 billion.  This amount represents the number of days remaining in the firm term of the drilling contract multiplied by the maximum contractual operating dayrate, excluding revenues for mobilization, demobilization, and contract preparation, or other incentive provisions or reimbursement revenues, which are generally insignificant to our contract drilling revenues.  Our contract backlog includes amounts associated with our contracted newbuild unitsunit that areis currently under construction but excludes amounts related to the conditional agreement we have for our second newbuild unit under construction.  The contractual operating dayrate may be higher than the actual dayrate we ultimately receive or an alternative contractual dayrate, such as waiting on weather rate, repair rate, standby rate or force majeure rate, may apply under certain circumstances.  The contractual operating dayrate may also be higher than the actual dayrate we ultimately receive due to a number of factors, including rig downtime or suspension of operations.  Several factors could cause rig downtime or a suspension of operations, including: equipment breakdowns and other unforeseen engineering problems, labor strikes and other work stoppages, shortages of material and skilled labor, surveys by government and maritime authorities, periodic classification surveys, severe weather or harsh operating conditions, and force majeure events.

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

- 9 -

to repudiate or renegotiate their contracts”).  Our inability to realize the full amount of our contract backlog may have a material adverse effect on our consolidated financial position, results of operations or cash flows.

We may not be able to renew or obtain new drilling contracts for rigs whose contracts are expiring or obtain drilling contracts for our stacked and idle rigs or our newbuild with a conditional agreement if the conditions thereof are not satisfied.

§

We may not be able to renew or obtain new drilling contracts for rigs whose contracts are expiring or obtain drilling contracts for our stacked and idle rigs or our uncontracted newbuilds.

The offshore drilling markets in which we compete experience fluctuations in the demand for drilling services.  Our ability to renew expiring drilling contracts or obtain new drilling contracts depends on the prevailing or expected market conditions at the time of expiration.  As of February 11, 2019,12, 2021, we have 1916 stacked or idle rigs and three ultra‑deepwater drillshipsone rig under construction that do not havehas a drilling contract that is subject to a final investment decision by the customer drilling contracts.and its partners.  We also have nineseven existing drilling contracts for our rigs that are currently operating, which are scheduled to expire before December 31, 2019.2021.  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 a drilling contractscontract for our newbuilds,newbuild unit with a conditional agreement in the event the conditions thereof are not satisfied, and there may be a gap in the operation of the rigs between the current contracts and subsequent contracts.  When oil and natural gas prices are low or it is expected that such prices will decrease in the future, we may be unable to obtain drilling contracts at attractive dayrates or at all.  We may not be able to obtain new drilling contracts in direct continuation with existing contracts or for our uncontracted newbuild units,unit with a conditional agreement, or depending on prevailing market conditions, we may enter into drilling contracts at dayrates substantially below the existing dayrates or on terms otherwise less favorable compared to existing contract terms, which may have an adverse effect on our consolidated financial position, results of operations or cash flows.

Our drilling contracts may be terminated due to a number of events, and, during depressed market conditions, our customers may seek to repudiate or renegotiate their contracts.

§

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,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.  Manyevents, many of these eventswhich are beyond our control.  During periods of depressed market conditions, we are subjectCertain customers who seek to an increased risk ofterminate our customers seekingdrilling contracts may attempt to repudiate their contracts, including through claims of non‑performance.  We are at continued risk of experiencing early contract terminations in a weak commodity price environment as operators look to reduce their capital expenditures.  During the years ended December 31, 2017 and 2016,defeat or circumvent our customers early terminated or cancelled contracts for one and eight of our rigs, respectively.protections against certain liabilities.  Our customers’ ability to perform their obligations under their drilling contracts, including their ability to fulfill their indemnity obligations to us, may also be negatively impacted by an economic downturn.  Our customers, which include national 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 on terms that are not as favorable as current terms, it could adversely affect our consolidated financial position, results of operations or cash flows.  See “Item 1. Business—Contract Drilling Services.”

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

§

We must make substantial capital and operating expenditures to maintain our active fleet or to reactivate our stacked or idle fleet, and we may be required to make significant capital expenditures to maintain our competitiveness, to execute our growth plan and to comply with laws and applicable regulations and standards of governmental authorities and organizations.

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

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

§

We have a substantial amount of debt, including secured debt, and we may lose the ability to obtain future financing and suffer competitive disadvantages.

At December 31, 2018Public health threats, such as COVID-19, have had, and 2017,may continue to have, significant adverse consequences for general economic, financial and business conditions, as well as for our total debt was $10.0 billionbusiness and $7.4 billion, respectively,operations.

Public health threats, pandemics and epidemics, such as the outbreak of which $2.6 billion and $1.4 billion, respectively, was secured.  This substantial levela novel strain of debtCOVID-19, severe influenza, other coronaviruses and other obligationshighly communicable viruses or diseases, have impacted and may continue to impact our operations directly or indirectly, including by disrupting the operations of our business partners, suppliers and customers in ways that adversely impact our operations.  For instance, the outbreak of COVID-19 and its development into a pandemic in March 2020 resulted in various actions by governmental authorities around the world to prevent or reduce the spread of COVID-19, such as imposing mandatory closures of all non-essential business facilities, seeking voluntary closures of such facilities and imposing restrictions on, or advisories with respect to, travel, business operations and public gatherings or interactions.  In addition, companies and individuals seeking to curtail the spread of COVID-19 have taken certain cautionary measures, such as companies around the world requiring employees to work remotely, suspending all non-essential travel worldwide for employees, and discouraging employee attendance at in-person work-related meetings, as well as individuals voluntarily social distancing and self-quarantining.  While many of these restrictions and measures have since been softened or lifted in varying degrees in different locations around the world, and there have been several COVID-19 vaccines recently approved by many governments that are expected to accelerate a recovery from the pandemic, the ultimate success of such vaccines is currently uncertain and resurgences in the spread of COVID-19 and other rapid developments with respect to the virus have prompted and may in the future prompt, the re-imposition of certain restrictions and measures.

These responses have significantly reduced global economic activity, as there has been a dramatic decrease in the number of businesses open for operation and a substantial reduction in the number of people across the world that have been going to work or leaving their house to purchase goods and services.  This has also resulted in airlines dramatically cutting back on flights and has reduced the number of cars on the road.  As a result, there has also been a sharp reduction in the demand for oil and a decline in oil prices.

We have taken similar precautionary measures intended to help minimize the risk to our business, employees, customers, suppliers and the communities in which we operate.  Our operational employees generally are currently still able to work on site and on our rigs.  We have taken comprehensive and global precautionary measures with respect to such operational employees, such as requiring them to verify they have not either experienced any symptoms consistent with COVID-19 or been in close contact with someone showing such symptoms before they are permitted to travel to the work site or rig, quarantining any operational employee on a rig who has shown signs of COVID-19, regardless of whether such employee has been confirmed to be infected, and imposing social distancing requirements in certain areas of the rig, such as in the dining hall and sleeping quarters, and are incurring incremental costs.  We are also actively assessing and planning for various operational contingencies; however, we cannot guarantee that any actions taken by us, including the precautionary measures noted above, will be effective in preventing either an outbreak of COVID-19 on one or more of our rigs or other adverse effects related to COVID-19.  To the extent an outbreak of COVID-19 develops on one or more of our rigs, we may have to temporarily shut down operations of such rig or rigs, which could result in significant downtime or contract termination and have substantial adverse consequences for our business and results of operations.  In addition, most of our non-operational employees are now working remotely, which increases various operational risks.  For instance, working remotely may increase the risk of security breaches or other cyber incidents or attacks, loss of data, fraud and other disruptions as a consequence of more employees accessing sensitive and critical information from remote locations.

Many governmental authorities across the globe have implemented travel restrictions and mandatory quarantine measures to prevent or reduce the spread of COVID-19, and in complying with such governmental actions, we have experienced, and expect to continue to experience, increased difficulties, delays and costs in moving our personnel in and out of, and to work in, the various jurisdictions in which we operate.  We may be unable to pass along these increased costs to our customers.  Additionally, disruptions to or restrictions on the ability of our suppliers, manufacturers and service providers to supply parts, equipment or services in the jurisdictions in which we operate or to progress the construction of our newbuild projects, whether as a result of government actions, labor shortages, the inability to source parts or equipment from affected locations, or other effects related to the COVID-19 outbreak, may have significant adverse consequences on our ability to meet our commitments to customers, including by increasing our operating costs and increasing the risk of rig downtime and could result in contract terminations.

Concerns over the prolonged negative effects of the COVID-19 outbreak on economic and business prospects across the world have also contributed to increased market and oil price volatility and have diminished expectations for the performance of the global economy.  These factors, coupled with the prospect of decreased business and future prospects, includingconsumer confidence and increased unemployment resulting from the following:

§

we may be unable to obtain financing in the future for working capital, capital expenditures, acquisitions, debt service requirements, distributions, share repurchases, or other purposes;

§

we may be unable to use operating cash flow in other areas of our business because we must dedicate a substantial portion of these funds to service the debt;

§

we could become more vulnerable to general adverse economic and industry conditions, including increases in interest rates, particularly given our substantial indebtedness, some of which bears interest at variable rates;

§

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

§

if we default under the terms of our secured financing arrangements, the secured debtholders may, among other things, foreclose on the collateral securing the debt, including the applicable drilling units; and

§

we may be less able to take advantage of significant business opportunities and to react to changes in market or industry conditions than our less levered competitors.

Various credit rating agencies have rated our debt below investment grade, which could limit our access to capital and have an adverse effect on our business and financial condition.

Two credit rating agenciesfor the financial condition of our customers or suppliers.  Such conditions have ratedresulted in, and may continue to result in, reductions to our non‑credit enhanced senior unsecured long‑term debt (our “Debt Rating”) below investment grade.  Our Debt Ratingscustomers’ drilling and production expenditures and delays or cancellations of projects, thus decreasing demand for our services, and an increased risk that our customers may seek price reductions or more favorable economic terms for our services, terminate our contracts or that we may be required to idle, stack or retire more of our rigs.  Additionally, any early termination payment made in connection with an early contract termination may not fully compensate us for the loss of the contract.  Accordingly, the actual amount of revenues earned may be substantially lower than the reported contract backlog.  To the extent our suppliers experience a deterioration in financial condition or operational capability as a result of such depressed market and industry conditions or we or other suppliers incur delays in moving personnel to and from drilling rigs, we may experience disruptions in supply, which could increase our operating costs and increase rig downtime.  The occurrence of any such events with respect to our customers, contracts or suppliers in certain cases has had, and may continue to have, significant adverse consequences for our business and financial position.

The magnitude and duration of potential social, economic and labor instability resulting from the COVID-19 outbreak, including how quickly national economies can recover once the pandemic subsides, or whether any recovery will ultimately experience a reversal or other setbacks, are uncertain and cannot be estimated at this time as such effects depend on future prospects and could cause the following:

§

limitations on our ability to access debt markets, including for the purpose of refinancing our existing debt or replacing our existing credit agreement;

§

less favorable terms and conditions on any refinancing arrangements, debt issuances or bank credit agreements, some of which could require collateral and restrict, among other things, our ability to pay distributions or repurchase shares;

§

increases to certain fees under our bank credit facilities and interest rates under indentures governing certain of our senior notes;

§

reduced willingness of current and prospective customers to transact business with us;

§

requirements from creditors or customers for additional insurance, guarantees and collateral;

§

limitations on our access to bank and third-party guarantees, surety bonds and letters of credit; and

§

reductions to or eliminations of the level of credit suppliers and financial institutions may provide through payment terms or intraday funding when dealing with us thereby increasing the need for higher levels of cash on hand, which would decrease our ability to repay debt balances.

Our Debt Ratings have caused someevents that are largely out of our control.  The ultimate extent of the effects listed above, and any further downgrades may cause or exacerbate, anyimpact of the effects listed aboveCOVID-19 outbreak on our business and financial position will depend largely on future developments, including the duration, spread or containment of the outbreak, particularly within the geographic locations where we operate, and the related impact on overall economic activity, all of which are highly uncertain at this time.  We are unable to predict the timing or impact of any such restructurings, if completed, on the capital structure and competitive dynamics among offshore drilling companies.

Public and investor sentiment towards climate change, fossil fuels and other esg matters could adversely affect our business, cost of capital and the price of our stock and other securities.

There have been efforts in recent years, based on changing public sentiment concerning fossil fuels, aimed at the investment community, including investment advisors, sovereign wealth funds, public pension funds, universities and other groups, to promote the divestment of shares of energy companies, as well as to pressure lenders and other financial services companies to limit or curtail activities with energy companies.  These efforts have intensified during the COVID-19 pandemic, as seen by the State of New York’s December 2020 announcement that it will be divesting the state’s Common Retirement Fund from fossil fuels.  If this or similar divestment efforts are successful, our stock price and our ability to access capital markets may be negatively impacted.

Members of the investment community are also increasing their focus on environmental, social and governance (“ESG”) practices and disclosures, including practices and disclosures related to greenhouse gases and climate change, in the energy industry in particular, and diversity and inclusion initiatives and governance standards among public companies more generally.  As a result, we may face increasing pressure regarding our ESG disclosures and practices.  Additionally, members of the investment community may screen companies such as ours for ESG sustainability performance before investing in our stock.  Over the past few years there has also been an acceleration in investor demand for ESG investing opportunities, and many large institutional investors have committed to increasing the percentage of their portfolios that are allocated towards ESG investments.  As a result, there has been a proliferation of ESG focused investment funds seeking ESG oriented investment products.  If we or our securities are unable to meet the sustainability ESG standards or investment criteria set by these investors and funds, we may lose investors or investors may allocate a portion of their capital away from us, our cost of capital may increase, our stock price and the price of our publicly traded debt securities may be negatively impacted and our reputation may also be negatively affected.

We rely heavily on a relatively small number of customers and the loss of a significant customer or a dispute that leads to the loss of a customer could have an adverse effect on our business and financial condition.business.

§

We rely heavily on a relatively small number of customers and the loss of a significant customer or a dispute that leads to the loss of a customer could have an adverse effect on our consolidated financial position, results of operations or cash flows.

We engage in offshore drilling services for most of the leading integrated oil companies or their affiliates, as well as for many government‑controlledgovernment-owned or government-controlled oil companies and other independent oil companies.  For the year ended December 31, 2018,2020, our most significant customers were Shell, ChevronEquinor and Equinor,Chevron, accounting for approximately 2628 percent, 2127 percent and 1814 percent, respectively, of our total contract drilling revenues.  As of February 11, 2019,12, 2021, the customers with the most significant aggregate amount of contract backlog were Shell, Equinor and Chevron, representing approximately 4553 percent, 2823 percent and 1513 percent, respectively, of our total contract backlog.  The loss of any of these customers or another significant customer, or a decline in payments under any of our drilling contracts, could, at least in the short term, have an adverse effect on our business and on our consolidated financial position, results of operations or cash flows.business.

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

§

Worldwide financial, economic and political conditions could have a material adverse effect on our consolidated financial position, results of operations or cash flows.

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

§

Our operating and maintenance costs will not necessarily fluctuate in proportion to changes in our operating revenues.

Our operating and maintenance costs will not necessarily fluctuate in proportion to changes in our operating revenues.  Costs for operating a rig are generally fixed or only semi‑variablesemi-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

-  11  -


because portions of the crew may be required to prepare rigs for stacking, after which time the crew members may be reassigned to active rigs or released.  As our rigs are mobilized from one geographic location to another, the labor and other operating and maintenance costs can vary significantly.  In general, labor costs increase primarily due to higher salary levels and inflation.  Equipment maintenance costs fluctuate depending upon the type of activity the unit is performing and the age and condition of the equipment, and these costs could increase for short or extended periods as a result of regulatory or customer requirements that raise maintenance standards above historical levels.  The amount of contract

- 12 -

Table of Contents

preparation and reactivation costs vary based on the scope and length of the contract preparation or reactivation project, and the recognition of such costs varies depending on the duration of the firm contractual period and other contract terms.

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

Our business involves numerous operating hazards, and our insurance and indemnities from our customers may not be adequate to cover potential losses from our operations.

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

The South China Sea, the Northwest Coast of Australia and the U.S. Gulf of Mexico are areas subject to typhoons, hurricanes or other extreme weather conditions on a relatively frequent basis, and our drilling rigs in these regions may be exposed to damage or total loss by these storms, some of which may not be covered by insurance.  The occurrence of these events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury to or death of rig personnel.  Some experts believe global climate change could increase the frequency and severity of these extreme weather conditions.  Operations may also be suspended because of machinery breakdowns, abnormal drilling conditions, failure of subcontractors to perform or supply goods or services, or personnel shortages.  We customarily provide contract indemnity to our customers for certain claims that could be asserted by us relating to damage to or loss of our equipment, including rigs, and claims that could be asserted by us or our employees relating to personal injury or loss of life.

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

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

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

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

- 13 -

more operating incidents, which in turn could decrease revenues and increase costs.  If increased competition for qualified personnel were to intensify in the future we may experience increases in costs or limits on operations.

Our labor costs and the operating restrictions under which we operate could increase as a result of collective bargaining negotiations and additional unionization efforts.

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

§

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

As of February 11, 2019,12, 2021, we had under construction four ultra‑deepwater drillships and one harsh environment semisubmersible, in which we have a partial ownership interest.two ultra-deepwater drillships.  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:

§

complications arising from pandemics and epidemics, such as the outbreak of a novel strain of COVID-19, severe influenza, other coronaviruses and other highly communicable viruses or diseases and associated government orders in the country where the rigs are being constructed or serviced and elsewhere;

shipyard availability, failures and difficulties;

§

shortages of equipment, materials or skilled labor;

§

unscheduled delays in the delivery of ordered materials and equipment;

§

design and engineering problems, including those relating to the commissioning of newly designed equipment;

§

latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions;

§

unanticipated actual or purported change orders;

§

disputes with shipyards and suppliers;

§

failure or delayed deliveries of significant partsmaterials or equipment for various reasons, including due to supplier shortages, constraints, disruption or quality issues;

§

availability of suppliers to recertify equipment for enhanced regulations;

§

strikes, labor disputes and work stoppages;

§

customer acceptance delays;

§

customer delays in providing customer-supplied engineering, approvals or equipment;

adverse weather conditions, including damage caused by such conditions;

§

terrorist acts, war, piracy and civil unrest;

§

unanticipated cost increases; and

§

difficulty in obtaining necessary permits or approvals.

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

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

Risks related to our indebtedness

We have a substantial amount of debt, including secured debt, and we may lose the ability to obtain future financing and suffer competitive disadvantages.

At December 31, 2020 and 2019, our total debt was $7.8 billion and $9.3 billion, respectively, of which $2.8 billion and $3.3 billion, respectively, was secured.  We have a bank credit agreement, as amended, that established a $1.3 billion secured revolving credit facility

for working capital, capital expenditures, acquisitions, debt service requirements, distributions, share repurchases, or other purposes;
we may be unable to use operating cash flow in other areas of our business because we must dedicate a substantial portion of these funds to service the debt;
we could become more vulnerable to general adverse economic and industry conditions, including increases in interest rates, particularly given our substantial indebtedness, some of which bears interest at variable rates;
we may be unable to meet financial ratios in the agreements governing certain of our debt and finance lease or satisfy certain other covenants and conditions included in our debt agreements, which could result in our inability to meet requirements for borrowings under our credit agreement or a default under these agreements, impose restrictions with respect to our access to certain of our capital, and trigger cross default provisions in our other debt instruments;
if we default under the terms of our secured financing arrangements, the secured debtholders may, among other things, foreclose on the collateral securing the debt, including the applicable drilling units;
we may be unable to obtain new investment or financing given recent environmental, social and governance influenced trends among many financial intermediaries, investors and other capital markets participants in reducing, or ceasing, lending to, or investing in, companies that operate in industries with higher perceived environmental exposure; and
we may be less able to take advantage of significant business opportunities and to react to changes in market or industry conditions than our less levered competitors.

See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Sources and uses of liquidity.”

Credit rating agencies have rated our debt below investment grade, which could limit our access to capital and have an adverse effect on our business and financial condition.

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

limitations on our ability to access debt markets, including for the purpose of refinancing our existing debt, replacing or extending our Secured Credit Facility;
less favorable terms and conditions on any refinancing arrangements, debt issuances or bank credit agreements, some of which could require collateral and restrict, among other things, our ability to pay distributions or repurchase shares;
increases to certain fees under our Secured Credit Facility and interest rates under indentures governing certain of our senior notes, which in the case of the 6.375% senior notes due December 2021, the 3.80% senior notes due October 2022, and the 7.375% senior notes due December 2041, have already reached the maximum rate increase of 2 percent pursuant to the related indenture due to the downgrades of certain rating agencies;
reduced willingness of current and prospective customers, suppliers and creditors to transact business with us;
requirements from creditors, suppliers or customers for additional insurance, guarantees and collateral;
limitations on our access to bank and third-party guarantees, surety bonds and letters of credit; and
reductions to or eliminations of the level of credit suppliers and financial institutions may provide through payment terms or intraday funding when dealing with us thereby increasing the need for higher levels of cash on hand, which would decrease our ability to repay debt balances.

Our Debt Ratings have caused some of the effects listed above, and any further downgrades may cause or exacerbate, any of the effects listed above and could have an adverse effect on our business and financial condition.

Worldwide financial, economic and political conditions could restrict our ability to access the capital markets, reduce our flexibility to react to changing economic and business conditions and reduce demand for our services.

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

Our business is affected by laws and regulations relating to the energy industry and the environment and safety, including international conventions and treaties, and regional, national, state, and local laws and regulations.  The offshore drilling industryOur business also depends on demand for services from the oil and gas exploration and production industry, and, accordingly, we are directly affected by the adoption of laws and regulations that, for economic, environmental or other policy reasons, curtail, delay or impose additional compliance costs and obligations related to the exploration and development drilling for oil and gas.  ComplianceOffshore drilling in certain areas has been curtailed and, in certain cases, prohibited because of environmental or safety concerns.  In addition, compliance with suchenvironmental and safety laws, regulations and standards, where applicable, may require us to make significant capital expenditures, such as the installation of costly equipment or implementation of operational changes, and may affect the resale values or useful lives of our rigs.  We may also incur additional costs in order to comply with other existing and future regulatory obligations or industry standards, including, but not limited to, costs relating to air emissions, including greenhouse gases, the management of ballast waters, maintenance and inspection, development and implementation of emergency procedures and maintenance of insurance coverage or other financial assurance of our ability to address pollution incidents.  OffshoreFor instance, in the last decade, enhanced governmental safety and environmental requirements applicable to our operations were adopted by U.S. federal agencies for drilling in certain areasthe U.S. Gulf of Mexico have caused, and may in the future cause, operators to have difficulties obtaining drilling permits in the U.S. Gulf of Mexico.  In addition, the oil and gas industry has been curtailedadopted new equipment and in certain cases, prohibited becauseoperating standards, such as the American Petroleum Institute Standard 53, related to the installation and testing of concerns over protection of the environment.  These costs could have a material adverse effect on our consolidated financial position, results of operations or cash flows.well control equipment.  A failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of our operations.  Additionally, our customers may elect to voluntarily comply with any non-mandatory laws, regulations or other standards.

operations for drilling rigs in the U.S. and non-U.S. offshore areas.  Any such effects could have a material adverse effect on our consolidated financial position, results of operations or cash flows.

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

As a contract driller with operations in certain offshore areas, we may be liable for damages and costs incurred in connection with oil spills or waste disposalsdisposal of wastes related to those operations, and we may also be subject to significant fines and other liabilities in connection with spills.  For example, an oil spill could result in significant liability, including fines, penalties and criminal liability and remediation, restoration or compensation costs for environmental or natural resource damages, as well as third-party damages, to the extent that the contractual indemnification provisions in our drilling contracts are not enforceable or otherwise sufficient, or if our customers are unwilling or unable to contractually indemnify us fromagainst 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.  LawsEnvironmental and safety laws and regulations protecting the environment have become moreincreasingly stringent in recent years, and may in some cases impose strict liability on facility or vessel owners or operators, rendering a person liable for environmental damage without regard to negligence.  These laws and regulations may expose us to liability for the conduct of, or conditions caused by, others or for acts that were in compliance with all applicable laws at the time they were performed.  The application of these requirements or the adoption of new requirements or measures could have a materialan adverse effect on our consolidated financial position, results of operations or cash flows.

Regulatory and various other risks, including litigation, associated with greenhouse gases and climate change could have an adverse impact on our business and demand for our services.

Scientific studies have suggested that emissions of certain gases, including greenhouse gases, such as carbon dioxide and methane, contribute to warming of the earth’s atmosphere and other climatic changes.  In response to such studies, the issue of climate change and the effect of greenhouse gas emissions, in particular emissions from the fossil fuel industry, has attracted considerable attention worldwide.  The attention to climate change has led, and we expect it to continue to lead, to additional regulations designed to reduce greenhouse gas emissions domestically and internationally.  Such attention could also result in other adverse impacts for the oil and gas industry, including further restrictions or bans imposed by lawmakers, lawsuits by governments or third-parties seeking recoveries for damages resulting from the combustion of fuels that may contribute to climate change effects, or reduced interest from investors if they elect

- 16 -

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

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

§

The global nature of our operations involves additional risks.

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

§

terrorist acts, war, piracy and civil unrest;

§

seizure, expropriation or nationalization of our equipment;

§

expropriation or nationalization of our customers’ property;

§

repudiation or nationalization of contracts;

§

imposition of trade or immigration barriers;

§

import‑exportimport-export quotas;

§

wage and price controls;

§

changes in law and regulatory requirements, including changes in interpretation and enforcement;

§

involvement in judicial proceedings in unfavorable jurisdictions;

§

damage to our equipment or violence directed at our employees, including kidnappings;

§

complications associated with supplying, repairing and replacing equipment in remote locations;

§

the inability to move income or capital; and

§

currency exchange fluctuations and currency exchange restrictions, including exchange or similar controls that may limit our ability to convert local currency into U.S. dollars and transfer funds out of a local jurisdiction.

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

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

Certain of our drilling contracts are partially payable in local currency.  The amounts, if any, of local currency received under these drilling contracts may exceed our local currency needs, leading to an accumulation of excess local currency balances, which, in

-  13  -


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

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

Table of Contents

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

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

§

Our business involves numerous operating hazards, and our insurance and indemnities from our customers may not be adequate

Failure to cover potential losses from our operations.

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

The South China Sea, the Northwest Coast of Australia and the U.S. Gulf of Mexico are areas subject to typhoons, hurricanes or other extreme weather conditions on a relatively frequent basis, and our drilling rigs in these regions may be exposed to damage or total loss by these storms, some of which may not be covered by insurance.  The occurrence of these events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury to or death of rig personnel.  Some experts believe global climate change could increase the frequency and severity of these extreme weather conditions.  Operations may also be suspended because of machinery breakdowns, abnormal drilling conditions, failure of subcontractors to perform or supply goods or services, or personnel shortages.  We customarily provide contract indemnity to our customers for certain claims that could be asserted by us relating to damage to or loss of our equipment, including rigs, and claims that could be asserted by us or our employees relating to personal injury or loss of life.

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

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

-  14  -


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

§

The continuing effects of the enhanced regulations enacted following the Macondo well incident and of agreements applicable to us could have an adverse effect on our business and worldwide operations.

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

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

§

Corporate restructuring activity, divestitures, acquisitions and other business combinations and reorganizations could adversely affect our ability to achieve our strategic goals.

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

§

we may be unable to realize the growth or investment opportunities, improvement of our financial position and other expected benefits by these activities in the expected time period or at all;

§

transactions may not be completed as scheduled or at all due to legal or regulatory requirements, market conditions or contractual and other conditions to which such transactions are subject;

§

unanticipated adverse consequences could arise in the integration or separation processes, including unanticipated restructuring or separation costs and liabilities, as well as delays or other difficulties in transitioning, coordinating, consolidating, replacing and integrating personnel, information and management systems, and customer products and services; and

§

the diversion of management and key employees' attention may detract from our ability to increase revenues and minimize costs.

§

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

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

§

Our labor costs and the operating restrictions under which we operate could increase as a result of collective bargaining negotiations and changes in labor laws and regulations.

Approximately 34 percent of our total workforce, primarily employed in Norway, Brazil, the U.K. and Australia, are represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially all of which are subject to annual salary negotiation.  These negotiations could result in higher personnel expenses, other increased costs or increased operational

-  15  -


restrictions as the outcome of such negotiations affect the market for all offshore employees not just the union members.  Legislation has been introduced in the U.S. Congress that could encourage additional unionization efforts in the U.S., as well as increase the chances that such efforts succeed.  Additional unionization efforts, if successful, new collective bargaining agreements or work stoppages could materially increase our labor costs and operating restrictions.

§

Failure to comply with anti‑briberyanti-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‑briberyanti-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‑briberyanti-bribery laws may conflict with local customs and practices.  If we are found to be liable for violations under the FCPA, the Bribery Act or other similar laws, either due to our acts or omissions or due to the acts or omissions of others, including our partners in our various joint ventures and of the current or former officers, directors or employees of any companies we have acquired, we could suffer from civil and criminal penalties or other sanctions, which could have a material adverse effect on our business or our consolidated financial position and results of operations.  In addition, investors could negatively view potential violations, inquiries or allegations of misconduct under the FCPA, the Bribery Act or similar laws, which could adversely affect our reputation and the market for our shares.

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

§

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

Scientific studies have suggested that emissions of certain gases, including greenhouse gases, carbon dioxide and methane, contribute to warming of the earth’s atmosphere and other climatic changes.  In response to such studies, the issue of climate change and the effect of greenhouse gas emissions, in particular emissions from fossil fuels, is attracting increasing attention worldwide.  For example, in December 2015, 195 nations adopted the Paris Agreement, which went into effect in November 2016.  The Paris Agreement aims to limit increases in global temperatures to well below two degrees Celsius.  While the greenhouse gas emission reductions called for by the Paris Agreement are not binding, we expect continued and increased attention to climate change.  This attention has led, and we expect it to continue to lead, to additional regulations designed to reduce greenhouse gas emissions domestically and internationally.  Because our business depends on the level of activity in the offshore oil and gas industry, existing or future laws, regulations, treaties or international agreements related to greenhouse gases and climate change, including incentives to conserve energy or use alternative energy sources, could have a negative impact on our business if such laws, regulations, treaties or international agreements reduce the worldwide demand for oil and gas or limit drilling opportunities.  In addition, such laws, regulations, treaties or international agreements could result in increased compliance costs or additional operating restrictions, which may have an adverse effect on our business.

§

We are subject to investigations and litigation that, if not resolved in our favor and not sufficiently insured against, could have a material adverse effect on us.

We are subject to a variety of disputes, investigations and litigation.  Certain of our subsidiaries are subject to and have been involved in litigation with certain of our customers.  We have subsidiaries that have issued debt under indentures that are subject to covenant compliance, some of which have been accused of breaching certain requirements of such covenants (see “Part II. Item 8. Financial Statementscustomers and Supplementary Data—Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies—Global Marine litigation”).other constituents.  Certain of our subsidiaries are named as defendants in numerous lawsuits alleging personal grievances or injury, including as a result of exposure to asbestos or toxic fumes or resulting from other occupational diseases, such as silicosis, and various other medical issues that can remain undiscovered for a considerable amount of time.  Some of these subsidiaries that have been put on notice of potential liabilities have no assets.  Certain subsidiaries are subject to litigation relating to environmental damage.  Our patent for dual‑activitydual-activity technology has been successfully challenged in certain jurisdictions.  We are also subject to a number of significant tax disputes.  We cannot predict the outcome of the investigations and cases involving thosethe Company or our subsidiaries or the potential costs to resolve them.  Insurance may not be applicable or sufficient in all cases, insurers may not remain solvent and policies may not be located.  Suits against non‑asset‑owningnon-asset-owning subsidiaries have and may in the future give rise to alter ego or successor‑in‑interestsuccessor-in-interest claims against us and our asset‑owningasset-owning subsidiaries to the extent a subsidiary is unable to pay a claim or insurance is not available or sufficient to cover the claims.  To the extent that one or more pending or future investigations or litigation matters is not resolved in our favor and is not covered by insurance, which could have an adverse effect on our financial position, results of operations or cash flows.

We are subject to cybersecurity risks and threats as well as increasing regulation of data privacy and security.

§

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

We depend on data and digital technologies to conduct our offshore and onshore operations, to collect payments from customers and to pay vendors and employees.  Our data protection measures and measures taken by our customers and vendors may not prevent

result from accidental technological failure.  In addition, breaches to our systems and systems of our customers and vendors could go unnoticed for some period of time.  Risks associated with these threats include disruptions of certain systems on our rigs; other impairments of our ability to conduct our operations; loss or ransom of intellectual property, proprietary information or customer and vendor data; disruption of our customers’ and vendors’ operations; misappropriation of assets; loss or damage to our customer and vendor data delivery systems; and increased costs to prevent, respond to or mitigate cybersecurity events.  A breach could also originate from, or compromise, our customers’ and vendors’ or other third-party networks outside of our control.  A breach may also result in legal claims or proceedings against us by our shareholders, employees, customers, vendors and governmental authorities, both U.S. and non-U.S.  If such a cyber‑incidentcyber-incident were to occur, it could have a material adverse effect on our business or on our consolidated financial position, results of operations or cash flows.

In addition, new laws and regulations governing data privacy and the unauthorized disclosure of personal data and confidential information, including the European Union General Data Protection Regulation, the Data Protection Law, as revised, of the Cayman Islands, the General Data Protection Law of Brazil and recentthe California legislation,Consumer Privacy Act, pose increasingly complex compliance challenges and potentiallypotential to elevate our costs.  Any failure by us to comply with these laws and regulations, including as a result of a security or privacy breach, could result in significant penalties, litigation and liabilities for us.  Additionally, if we acquire a company that has violated or is not in compliance with applicable data protection laws, we may incur significant liabilities and penalties as a result.

Acts of terrorism, piracy and political and social unrest could affect the markets for drilling services.

§

Acts of terrorism, 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 certain risks, such as terrorist acts, piracy, vandalism, sabotage, civil unrest, expropriation and acts of war, and we do not carry insurance for loss of revenues resulting from such risks.

§

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

Public health threats, such as Severe Acute Respiratory Syndrome, severe influenza and other highly communicable virusesRisks related to taxes

A change in tax laws, treaties or diseases, outbreaksregulations, or their interpretation, of which have already occurred in various parts of the worldany country in which we operate,have operations, are incorporated or are resident could adversely impact our operations, the operations of our customers and the global economy, including the worldwide demand for oil and natural gas and the level of demand for our services.  The quarantine of personnel or inability to access our offices or rigs could adversely affect our operations.  Travel restrictions or operational problems in any part of the world in which we operate, or any reduction in the demand for drilling services caused by public health threats in the future, may materially impact our operations and have an adverse effect on our results of operations.

§

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

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

§

We have incurred significant transaction and acquisition-related costs and may incur significant integration costs in connection with the acquisitions.

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

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

§

A change in tax laws, treaties or regulations, or their interpretation, of any country in which we have operations, are incorporated or are resident could result in a higher effective tax rate on our worldwide earnings, which could result in a significant adverse effect on our earnings and cash flows from operations.

We are subject to changes in applicable tax laws, treaties or regulations in the jurisdictions in which we operate and earn income, and such changes could include laws or policies directed toward companies organized in jurisdictions with low tax rates.  A material change inrates with the intent to increase 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.burden.  Switzerland, for example, has been carefully considering variousenacted tax reform proposals in response to certain guidance from and demands by the European Union (“EU”)EU and the Organization for Economic Co‑operationCo-operation and Development (the “OECD”).  Some of these tax reform measures may be adopted into law and effective as early as 2019.January 2022.  Similarly, the OECD issued its action plan of tax reform measures that called for member states to take action to prevent base erosion and profit shifting.  Some of these measures impact transfer pricing, requirements to qualify for tax treaty benefits, and the definition of permanent establishments depending on each jurisdiction’s adoption and interpretation of such proposals.  Respective countries have adopted various measures into their own tax laws.  In addition, the EU issued its Anti‑TaxAnti-Tax Avoidance DirectiveDirectives in 2016 and 2017 that required its member states to adopt specific tax reform measures bystarting in 2019.  Other tax jurisdictions in which we operate may consider implementing similar legislation.  Any material change to tax laws, treaties, regulations or policies, their interpretation or application, or the adoption of new interpretations of existing laws and rulings, in any of the jurisdictions in which we operate, are incorporated or resident, could result in a higher effective tax rate on our worldwide earnings and such change could have a significant adverse effect on our consolidated financial position, results of operations or cash flows.

A loss of a major tax dispute or a successful tax challenge to our operating structure, intercompany pricing policies or the taxable presence of our key subsidiaries in certain countries could result in a higher effective tax rate on our consolidated earnings and increase our cash tax payments.

§

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

We are subject to tax laws, treaties and regulations in the countries in which we operate and earn income.  Our income taxes are based on the applicable tax laws and tax rates in effect in the countries in which we operate and earn income as well as upon our operating structures in these countries.  Our income tax returns are subject to review and examination in these jurisdictions, and we do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority.  If any tax authority successfully challenges our operational structure, intercompany pricing policies or the taxable presence of our key subsidiaries in certain countries; or if the terms of certain income tax treaties are interpreted in a manner that is adverse to our structure; or if we lose a material tax dispute in any country, particularly in the U.S., India, Brazil or Nigeria, our effective tax rate on our worldwide earnings could increase substantially and our earnings and cash flows from operations could be materially adversely affected.  For example, we cannot be certainbelieve that theneither we nor our non-U.S. subsidiaries, other than those that report a U.S. Internal Revenue Service (“IRS”) will not successfully contend that wetrade or any of our key subsidiariesbusiness or a U.S. permanent establishment, were or are engaged in a trade or business in the U.S. or, that we or any of our key subsidiariesif applicable, maintained or maintain a permanent establishment in the U.S.  The determination of the aforementioned, among other things, involves considerable uncertainty.  If we or any of our key subsidiaries were determined to have been engaged in a trade or business in the U.S. through a permanent establishment,Internal Revenue Service (the “IRS”) were to disagree, then we could be subject to additional U.S. corporate income and additional branch profits taxes on the portion of our earnings effectively connected to such U.S. business or, if applicable,

attributable to such U.S. permanent establishment during the period in which this was considered to have occurred.  If this occurs, our effective tax rate on worldwide earnings for that period could increase substantially, we could be subject to assessments in previously filed returns that remain open to audit and our earnings and cash flows from operations for that period could be adversely affected.

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. shareholders.

§

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

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

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

If we were treated as a PFIC for any taxable year, our U.S. shareholders would face adverse U.S. tax consequences.  Under the PFIC rules, unless a shareholder makes certain elections available under the Internal Revenue Code of 1986, as amended, and suchwhich elections could themselves have adverse consequences for the shareholder, the shareholder could be required to pay U.S. federal income tax at the highest applicable income tax rates on ordinary income upon the receipt of excess distributions, as defined for U.S. tax purposes, and upon any gain from the disposition of our shares, plus interest on such amounts, as if such excess distribution or gain had been recognized ratably over the shareholder’s holding period of our shares.  Additionally, under applicable statutory provisions, the preferential tax rate on qualified dividend income, which applies to dividends paid to non‑corporatenon-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.

Risks related to our jurisdiction of organization and governing documents

As a Swiss corporation, our flexibility may be limited with respect to certain aspects of capital management AND swift implementation of certain initiatives or strategies.

§

As a Swiss corporation, our flexibility may be limited with respect to certain aspects of capital management, and we may be unable to make distributions or repurchase shares without subjecting our shareholders to Swiss withholding tax.

Under Swiss law, our shareholders may approve an authorized share capital that allows the board of directors to issue new shares without additional shareholder approval within a period of up to two years.  The authorized share capital is limitedyears and for up to a maximum of 50 percent of a company’s registeredissued share capital.  The authorized share capital approved by our shareholders at the May 20182020 annual general meeting will expire on May 18, 2020.7, 2022.  Our currently available authorized share capital is limited to approximately 29 percent of our issued share capital as of February 16, 2021.  Accordingly, shareholders at our annual general meeting in May 2019 are not expected to2021 may be requested to approve a renewal and an increase in authorized share capital.  Our current authorized share capital is limited to approximately five percent of our registered share capital.  Additionally, subject to certain exceptions, Swiss law grants preemptive rights to existing shareholders to subscribe for new issuances of shares.  Further, Swiss law does not provide as much flexibility in the various terms that can attach to different classes of shares as the laws of some other jurisdictions.  Swiss law also reserves for shareholder approval certain corporate actions over which a board of directors would have authority in some other jurisdictions.  For example, dividends must be approved by shareholders.  These Swiss law requirements relating to our capital management may limit our flexibility, and situations may arise where greater flexibility would have provided substantial benefits to our shareholders.

Distributions to shareholders in the form of a par value reduction and dividend distributions out of qualifying additional paid‑inpaid-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‑inpaid-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‑inpaid-in capital as shown on Transocean Ltd.’s standalone Swiss statutory financial statements, we may not be able to make distributions without subjecting our shareholders to Swiss withholding taxes.

Under Swiss tax law, repurchases of shares for the purposes of capital reduction are treated as a partial liquidation subject to a 35 percent Swiss withholding tax based on the difference between the repurchase price and the related amount of par value and the related amount of qualifying additional paid‑inpaid-in capital, if any.  At our 2009 annual general meeting, our shareholders approved the repurchase of up to CHF 3.5 billion of our shares for cancellation under the share repurchase program.  If we repurchase shares, we expect to use an alternative procedure pursuant to which we repurchase shares via a “virtual second trading line” from market players, such as banks and

- 20 -

Table of Contents

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

-  19  -


§

Swiss corporate governance may affect our business.

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

§

As a Swiss corporation, we are subject to Swiss legal provisions that may limit our flexibility to swiftly implement certain initiatives or strategies.

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

These Swiss law requirements could limit our flexibility to swiftly implement certain initiatives or strategies.

§

We are subject to anti‑takeover

We are subject to anti-takeover provisions.

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

§

provide that the board of directors is authorized, subject to obtaining shareholder approval every two years, at any time during a maximum two‑yeartwo-year period, which under our current authorized share capital will expire on May 18, 2020,7, 2022, to issue a specified number of shares, which under our current authorized share capital is approximately five29 percent of the share capital registered in the commercial register as of February 16, 2021, 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 2422 percent of the share capital registered in the commercial register as of February 12, 2019,16, 2021, 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‑basedshare-based awards;

§

provide that any shareholder who wishes to propose any business or to nominate a person or persons for election as director at any annual meeting may only do so if we are given advance notice;

§

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

§

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

§

provide that any action required or permitted to be taken by the holders of shares must be taken at a duly called annual or extraordinary general meeting of shareholders;

§

limit the ability of our shareholders to amend or repeal some provisions of our articles of association; and

limit transactions between us and an “interested shareholder,” which is generally defined as a shareholder that, together with its affiliates and associates, beneficially, directly or indirectly, owns 15 percent or more of our shares entitled to vote at a general meeting.

limit transactions between us and an “interested shareholder,” which is generally defined as a shareholder that, together with its affiliates and associates, beneficially, directly or indirectly, owns 15 percent or more of our shares entitled to vote at a general meeting.

§

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

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

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

Shareholder Matters

Share issuance

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

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‑Swissnon-Swiss holder is not subject to Swiss income taxes on dividend income and similar distributions in respect of our shares, unless the shares are attributable to a permanent establishment or a fixed place of business maintained in Switzerland by such non‑Swissnon-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‑Swissnon-Swiss holder is not subject to Swiss wealth taxes unless the holder’s shares are attributable to a permanent establishment or a fixed place of business maintained in Switzerland by such non‑Swissnon-Swiss holder.

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

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

Exemption

Exemption—Distributions to shareholders in the form of a par value reduction or out of qualifying additional paid‑inpaid-in capital for Swiss statutory purposes are exempt from Swiss withholding tax.  On December 31, 2018,2020, the aggregate amount of par value of our outstanding shares was CHF 6161.5 million, equivalent to approximately $62$69.5 million, and the aggregate amount of qualifying additional paid‑in

-  23  -


paid-in capital of our outstanding shares was CHF 13.413.5 billion, equivalent to approximately $13.7$15.3 billion.  Consequently, we expect that a substantial amount of any potential future distributions may be exempt from Swiss withholding tax.

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

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

Refund available to United States (“U.S.”) residents—The Swiss‑U.S.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.‑SwissU.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.  

- 24 -

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 sharesShares repurchased for the purposespurpose of capital reduction are treated as a partial liquidation subject to a 35 percent Swiss withholding tax based on the difference between the repurchase price and the related amount of par value and the related amount of qualifying additional paid‑inpaid-in capital, if any.  We would be required to remit on a net basis the purchase price with the Swiss withholding tax deducted to a holder of our shares and pay the withholding tax to the Swiss federal tax authorities.  However, for such repurchased shares, the portions of the repurchase price that are attributable to the par value and the qualifying additional paid‑inpaid-in capital for Swiss statutory reporting purposes are not subject to the Swiss withholding tax.

If we repurchase shares, we expect to use an alternative procedure pursuant to which we repurchase our shares via a "virtual second trading line" from market players, such as banks and institutional investors, who are generally entitled to receive a full refund of the Swiss withholding tax.  The use of such “virtual second trading line” with respect to share repurchase programs is subject to approval of the competent Swiss tax and other authorities.  We may not be able to repurchase as many shares as we would like to repurchase for purposes of capital reduction on the “virtual second trading line” without subjecting the selling shareholders to Swiss withholding taxes.  The repurchase of shares for purposes other than for cancellation, such as to retain as treasury shares for use in connection with stock incentive plans, convertible debt or other instruments within certain periods, are not generally subject to Swiss withholding tax.

Under Swiss corporate law, the right of a company and its subsidiaries to repurchase and hold its own shares is limited.  A company may repurchase its shares to the extent it has freely distributable reserves as shown on its Swiss statutory balance sheet in the amount of the purchase price and if the aggregate par value of all shares held by the company as treasury shares does not exceed 10 percent of the company’s share capital recorded in the Swiss Commercial Register, whereby for purposes of determining whether the 10 percent threshold has been reached, shares repurchased under a share repurchase program for cancellation purposes authorized by the company’s shareholders are disregarded.  As of February 11, 2019,16, 2021, Transocean Inc., our wholly owned subsidiary, held as treasury shares less than onefour percent of our issued shares.and outstanding shares as of such date.  Our board of directors could, to the extent freely distributable reserves are available, authorize the repurchase of additional shares for purposes other than cancellation, such as to retain treasury shares for use in satisfying our obligations in connection with incentive plans or other rights to acquire our shares.  Based on the current number of shares held as treasury shares as of February 16, 2021, approximately ninesix percent of our issued and outstanding shares could be repurchased for purposes of retention as additional treasury

-  24  -


shares.  Although our board of directors has not approved such a share repurchase program for the purpose of retaining repurchased shares as treasury shares, if it did so, any such shares repurchased would be in addition to any shares repurchased under the currently approved program.

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.report on Form 10-K.  The following discussion of our results of operations and liquidity and capital resources includes comparisons for the years ended December 31, 2020 and 2019.  For a discussion, including comparisons, of our results of operations and liquidity and capital resources for the years ended December 31, 2019 and 2018, see “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K for the year ended December 31, 2019, filed with the United States (“U.S.”) Securities and Exchange Commission on February 18, 2020.

Business

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” the “Company,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells.  As of February 11, 2019,16, 2021, we owned or had partial ownership interests in and operated a fleet of 4937 mobile offshore drilling units, including 31 ultra‑deepwater floaters, 14 harsh environment27 ultra-deepwater floaters and four midwater10 harsh environment floaters.  As of February 11, 2019,16, 2021, we were constructing (i) four additional ultra‑deepwater drillships and (ii) one additional harsh environment semisubmersible, in which we hold a partial ownership interest.two ultra-deepwater drillships.

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

Our contract drilling services operations are geographically dispersed in oil and gas exploration and development areas throughout the world.  Although rigs can be moved from one region to another, the cost of moving rigs and the availability of rig‑movingrig-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.

Outlook

Drilling marketOur long‑term viewSince 2014, the industry has experienced a severe cyclical downturn of considerably longer duration than those previously observed.  Multiple years of volatile and generally weak commodity prices, exacerbated in 2020 by the effects of the partcoronavirus (“COVID-19”) pandemic and production disputes among major oil producing countries, have resulted in our customers repeatedly delaying offshore investment decisions and postponing exploration and development programs. Some of our customers have also recently committed to invest or increase investment in low carbon and renewable energy resources, potentially reducing their expenditures in the development and production of hydrocarbons over the coming decades.  However, even in the context of some diversion of investment away from traditional sources of energy, the structural efficiency gains achieved by the offshore drilling market in which we participate is positive, especially for the highest specification floaters.  Brent oil prices, although somewhat volatile, remained above $60 per barrel for most of 2018, improving our customers’ economics for drilling oil and gas wellssegment in the past six years have materially improved the economics of deepwater offshore development projects, making the segment a competitive source of new supply.

We anticipate that the subdued level of contract activity will continue for at least the first half of 2021, although we believe that by the second half of 2021, our customers will again focus on favorable deepwater offshore economics and providing positive supportbegin increasing their exploration, production and reserve replacement activities by restarting delayed projects and commencing new campaigns.  This depends on many variables, including global amelioration of the COVID-19 pandemic, and the effects of actions by some governments and regulators intended to curtail existing and future drilling activities, and other factors.  Ultimately, as the hydrocarbon supply-demand balance improves, including as the result of a post-pandemic global economic recovery, we expect a sustained improvement of oil prices, which will result in greater demand for our customers’ budget cycles for 2019.  Structural efficiency gains across the industry, which resultedhigh-specification fleet of assets, resulting in improved economics for offshore development, and some favorable trends in the hydrocarbon supply‑demand balance whereby oil supply has declined relative to demand, resulted in an increase in our customers’ investment decisions in 2018.  We expect this trendfurther improvement of additional investment by our customers to continue in 2019.dayrates.

Over the past year, opportunities have increased for our drilling services.  In markets requiring harsh environment floating drilling rigs, such as the Norwegian North Sea and eastern Canada, the limited supply of these specialized high-specification rigs has improved fleetcontinued to result in strong utilization which has resulted in increased dayrates on high‑specificationand dayrates.  In the ultra-deepwater markets, we have seen accelerated retirement of idle rigs, being tendered for new work.  Outsideand with the anticipated consolidation of harsh environment markets, the excess supply of ultra‑deepwater floaters relative to demand has delayed improvement of dayrates despite the increase in contract activity.  However, as the hydrocarbon supply‑demand balance improves,distressed drilling contractors, we expect that stabilityadditional retirements will reduce supply and sustained improvement of oil prices will ultimately result in greater demandimprove utilization and dayrate metrics for ultra‑deepwater drilling rigs and improvement of dayrates as utilization tightens.high-specification assets.

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 andor is not committed to

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, contract preparation, other incentive provisions or reimbursement revenues, which are not expected to be significant to our contract drilling revenues.  Average contractual dayrate relative to our contract backlog is defined as the average maximum contractual operating dayrate to be earned per operating day in the measurement period.  An operating day is defined as a day for which a rig is contracted to earn a dayrate during the firm contract period after commencement of operations.

-  28  -


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.period.

We believe our industry leading contract backlog sets us apart from the competition.  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.  It does not include conditional agreements and options to extend firm commitments.  Our contract backlog includes amounts associated with our contracted newbuild unitsunit that areis currently under construction but excludes amounts related to the conditional agreement we have for our second newbuild unit 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‑weatherwaiting-on-weather rate, repair rate, standby rate or force majeure rate, may apply under certain circumstances.  The contractual operating dayrate may also be higher than the actual dayrate we ultimately receive because of a number of factors, including rig downtime or suspension of operations.  In certain contracts, the dayrate may be reduced to zero if, for example, repairs extend beyond a stated period of time.

In connection withAverage contractual dayrate relative to our Ocean Rig acquisition, we acquired contract backlog of approximately $650 million, includedis defined as the average maximum contractual operating dayrate to be earned per operating day in the contract backlogmeasurement period.  An operating day is defined as a day for our ultra‑deepwater and harsh environment floaters presented above, measured as of the acquisition date, December 5, 2018.  In connection with our Songa acquisition, we acquired contract backlog of $3.7 billion, included in the contract backlog for our harsh environment floaters presented above, measured as of the acquisition date, January 30, 2018.

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

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 aremay be available to our customers under certain circumstances.

Our average daily revenue fluctuates relative to market conditions and our revenue efficiency.  The average daily revenue may also be affected by revenues for lump sum bonuses or demobilization fees received from our customers and is reduced by the amortization of the contract intangible assets acquired in the Songa acquisition and, to a lesser extent, the Ocean Rig acquisition.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‑specificationhigh-specification jackups are typically contracted at lower dayrates compared to ultra‑deepwaterultra-deepwater floaters and harsh environment floaters.  We no longer operate deepwater floaters, midwater floaters or high-specification jackups.  We include newbuilds in the calculation when the rigs commence operations upon acceptance by the customer.  We remove rigs from the calculation upon disposal or classification as held for sale, unless we continue to operate rigs subsequent to sale, as we did with three of the high‑specification jackups sold in May 2017, in which case we remove the rigs at the time of completion or novation of the contract.

Revenue efficiency—Revenue efficiency is defined as actual contract drilling revenues, excluding revenues for contract terminations and reimbursements, for the measurement period divided by the maximum revenue calculated for the measurement period, expressed as a percentage.  Maximum revenue is defined as the greatest amount of contract drilling revenues, excluding revenues fromfor contract terminations and reimbursements, the drilling unit could earn for the measurement period, excluding amounts related to incentive provisions.  The revenue efficiency rates for our fleet were as follows:

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

Rig utilization—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:

Loss on impairment or disposal of assets—In the year ended December 31, 2018,2020, we recognized losses related toa loss on the following: (a) $999impairment of assets, including an aggregate net loss of $556 million associated with assets that we determined were impaired at the impairment of certain assetstime we classified them as held for sale, and (b) $462 million associated with the impairment of goodwill.    In the year ended December 31, 2017, we recognized losses related to the following: (a) a loss of $1.4 billion associated with the impairment of certain assets classified as held for sale and (b) a loss of $94$31 million associated with the impairment of our midwater floater asset group.group and a loss of $10 million associated with the impairment of other assets .  In the year ended December 31, 2019, we recognized an aggregate loss of $583 million, primarily associated with certain assets that we determined were impaired at the time we classified them as held for sale, and an aggregate loss of $26 million associated with the impairment of right-of-use assets and leasehold improvements.

In the year ended December 31, 2018,2020, we recognized an aggregate gainloss of $7$61 million associated with the sale of six ultra‑deepwaterone ultra-deepwater floater, three harsh environment floaters one deepwater floater and onethree midwater floater,floaters, along with related assets.  In the year ended December 31, 2018,2019, we recognized an aggregate gain of $4 million associated with the sale of six ultra-deepwater floaters, one harsh environment floater, two deepwater floaters and two midwater floaters, along with related assets.  In the years ended December 31, 2020 and 2019, we recognized an aggregate loss of $7$23 million and $16 million, respectively, associated with the disposal of assets unrelated to rig sales.  In the year ended December 31, 2017, loss on disposal of assets was primarily due to the sale of 10 high‑specification jackups and novation of the contracts relating to the construction of five high‑specification jackups, together with related assets.

Other income and expense—Interest expense, net of amounts capitalized, increaseddecreased in the year ended December 31, 20182020, compared to the year ended December 31, 2017,2019, primarily due to a decrease of $155 million resulting from the debt retired, repaid or restructured, partially offset by an increase of $78 million primarily resulting from debt issued.

In the year ended December 31, 2020, we recognized a net gain on restructuring and retirement of debt, primarily due to the following: (a) approximately $98an aggregate gain of $427 million reduced interest costs capitalized for our newbuild ultra‑deepwater drillships placed into serviceassociated with the restructuring of debt in the two‑Exchange Transactions, (b) an aggregate gain of $135 million associated with the retirement of $360 million aggregate principal amount of our debt securities in the 2020 Tender Offers, (c) an aggregate gain of $36 million associated with the retirement of $147 million aggregate principal amount of our debt securities repurchased in the open market, partially offset by (d) a loss of $65 million associated with the full redemption of the 9.00% Senior Notes due July 2023.  In the year period ended December 31, 2018, (b) approximately $78 million resulting from2019, we recognized a net loss on retirement of debt, issued in the two‑year period ended December 31, 2018 and (c) approximately $32 million resulting from the debt and related undesignated derivative instruments issued or assumed in connection with the Songa acquisition.  These increases were partially offset byincluding a decreaseloss of approximately $83$23 million resulting from the retirement of debt.

Loss on retirement$434 million aggregate principal amount of our debt securities repurchased in the year ended December 31, 2017 resulted primarily from the following: (a) an aggregateopen market and a loss of $48$18 million resulting from the retirement of notes validly tendered in the cash tender offers completed July 11, 2017notes (the “2017 Tender Offers”“2019 Tendered Notes”) and (b) an aggregate loss of $7 million resulting from debt redemptions and repurchases..

Other income,expense, net, increased in the year ended December 31, 20182020, compared to the year ended December 31, 2017,2019, primarily due to the following: (a) an increasea gain of $45$132 million associated with receiptrecognized in the prior year resulting from the termination of payments related to our dual‑activity patent,construction contracts, (b) an increasea loss of $15$59 million recognized in the year ended December 31, 2020, associated with the non‑service componentimpairment of our equity-method investment in Orion, (c) increased net periodic benefit costs (c)of $14 million primarily from settlement of certain defined benefit plans in Norway, (d) increased loss of $10 million associated with the bargain purchase gain resulting from the Ocean Rig acquisition with no comparable activitynet changes in currency exchange rates and (e) a gain of $11 million recognized in the prior year and (d) $4 million associated with undesignated interest rate swaps acquired inresulting from the Songa acquisition and subsequently terminatedbargain purchase of Ocean Rig completed in the year ended December 31, 2018, with no comparable activity in the prior year.  These increases were partially offset by a decrease(f) increased income of $33$9 million associated with currency exchange, $21related to our investment in Orion and (g) increased income of $5 million of which resulted from undesignated currency derivative instruments in the current year.related to our dual-activity patent.

Income tax expense—In the years ended December 31, 20182020 and 2017,2019, our effective tax rate was (12.8)(5.1) percent and (3.1)(4.9) percent, respectively, based on loss before income tax expense.  In the years ended December 31, 20182020 and 2017, the effect of the various2019, discrete period tax items represented a net tax expensebenefit of $143$91 million and a net tax benefit of $37$150 million, respectively.  In the year ended December 31, 2018, such2020, we identified certain discrete items, were primarily related tosuch as losses on impairment and disposal of assets, gain on restructuring and retirement of debt, revenues recognized for the United States (“settlement of disputes, the loss on impairment of an investment in an unconsolidated affiliate, the carryback of net operating losses in the U.S.”) transition as a result of the Coronavirus Aid, Relief, and Economic Security Act, which included the release of valuation allowances previously recorded, settlements and expirations of various uncertain tax on non‑U.S. earnings.positions and accruals for withholding taxes.  In the year ended December 31, 2017, such2019, we identified certain discrete items, were primarily related to the tax benefitsuch as losses on impairment and disposal of changes in unrecognized tax benefits associated withassets, settlements and expirations of various uncertain tax positions takenand adjustments to our deferred taxes for operating structural changes made in prior years, valuation allowances on deferred tax assets and foreign tax credits not expected to be realized, remeasurement of the U.S. deferred tax assets for a tax rate change as a result of the enactment of the Tax Cuts and Jobs Act (the “2017 Tax Act”) and deductions related to resolution of certain litigation matters related to Macondo well incident.  In the years ended December 31, 20182020 and 2017,2019, our effective tax rate, excluding discrete items, was (29.2)(23.4) percent and 95.2(30.7) percent, respectively, based on loss before income tax expense.  Our effective tax rate decreasedincreased in the year ended December 31, 20182020 compared to the year ended December 31, 2017,2019, primarily due to changes in the relative blend of income from operations in certain jurisdictions and a decreased loss before income taxes, andpartially offset by tax benefits for the increased tax expensecarryback of net operating losses in the U.S. as a result of the U.S. base erosionCoronavirus Aid, Relief, and anti‑abuseEconomic Security Act, which included the release of previously recorded valuation allowances, settlements and expirations of uncertain tax (“BEAT”).

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

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

Due to factors related to our operating activities and organizational structure, our income tax expense does not change proportionally with our income before income taxes.  Significant decreases in our income before income taxes typically lead to higher effective tax rates, while significant increases in income before income taxes can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above.  With respect to the effective tax rate calculation for the year ended December 31, 2018, a significant portion of our income tax expense was generated in countries in which income taxes are imposed on gross revenues, with the most significant of these countries being India.  Conversely, the countries in which we incurred the most significant income taxes during this period that were based on income before income tax include Brazil, Switzerland, Norway, the United Kingdom (“U.K.”) and the U.S.  Our rig operating structures further complicate our tax calculations, especially in instances where we have more than one operating structure for the particular taxing jurisdiction and, thus, more than one method of calculating taxes depending on the operating structure utilized by the rig under the contract.  For example, two rigs operating in the same country could generate significantly different provisions for income taxes if they are owned by two different subsidiaries that are subject to differing tax laws and regulations in the respective country of incorporation.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes.

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

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

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

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

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

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

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

In the year ended December 31, 2017, loss on disposal of assets was primarily due to the sale of 10 high‑specification jackups and novation of the contracts relating to the construction of five high‑specification jackups, together with related assets.

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

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

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

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

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

-  34  -


income changes during the carryforward periods or if the cumulative loss is no longer present, we may adjust the amount of deferred tax assets that we expect to realize.

Due to factors related to our operating activities and organizational structure, our income tax expense does not change proportionally with our income before income taxes.  Significant decreases in our income before income taxes typically lead to higher effective tax rates, while significant increases in income before income taxes can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above.  With respect to the effective tax rate calculation for the year ended December 31, 2017,2020, a significant portion of our income tax expense was generated in countries in which income taxes are imposed on gross revenues, with the most significant of these countries being Angola and India.  Conversely, the countries in which we incurred the most significant income taxes during this period that were based on income before income tax include Brazil, Switzerland, Norway, the U.K. and the U.S., Switzerland, Brazil, the United Kingdom and Norway.  Our rig operating structures further

- 31 -

complicate our tax calculations, especially in instances where we have more than one operating structure for the particular taxing jurisdiction and, thus, more than one method of calculating taxes depending on the operating structure utilized by the rig under the contract.  For example, two rigs operating in the same country could generate significantly different provisions for income taxes if they are owned by two different subsidiaries that are subject to differing tax laws and regulations in the respective country of incorporation.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes.

Sources and uses of liquidity

Overview—We expect to use existing unrestricted cash balances, internally generated cash flows, borrowings under the Secured Credit Facility, proceeds from the disposal of assets or proceeds from the issuance of additional debt or equity 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.providers or issuing shares from our authorized share capital.  Subject to market conditions and other factors, we may also be required to provide collateral for any future financing arrangements.

- 32 -

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

The effects of the COVID-19 pandemic and the volatility in oil prices could have significant adverse consequences for general economic, financial and business conditions, as well as for our business and financial position and the business and financial position of our customers and suppliers and may, among other things, impact our ability to generate cash flows from operations, access the capital markets on acceptable terms or at all, and affect our future need or ability to borrow under our Secured Credit Facility.  In addition to our potential sources of funding, the effects of such global events may impact our liquidity or need to alter our allocation or sources of capital, implement further cost reduction measures and change our financial strategy.  Although the COVID-19 pandemic and the volatility in oil prices could have a broad range of effects on our sources and uses of liquidity, the ultimate effect thereon, if any, will depend on future developments, which cannot be predicted at this time.

Our internally generated cash flows are directly related to our business and the market sectors in which we operate.  We have generated positive cash flows from operating activities over recent years and, although we cannot provide assurances, we currently expect that such cash flows will continue to be positive over the next year.  However, among other factors, if the drilling market deteriorates, or if we experience poor operating results, or if we incur expenses to, for example, reactivate, stack or otherwise assure the marketability of our fleet, cash flows from operations may be reduced or negative.

Our access to debt and equity markets may beis currently limited due to a variety of events, including, among others, credit rating agency downgrades of our debt ratings, industry conditions, general economic conditions, industry conditions, market conditions and market perceptions of us and our industry.industry and credit rating agencies’ views of our debt.  The rating of the majority of our non‑credit enhanced senior unsecured long‑termlong-term debt (“Debt Rating”) is below investment grade.  SuchThe Debt Rating has causedis causing us to experience increased fees and interest rates under our Secured Credit Facility and agreements governing certain of our senior notes.  FurtherFuture downgrades may affect or limitfurther restrict our ability to access the debt markets inmarket for sources of capital and may negatively impact the future.  Our ability to accesscost of such markets may be severely restrictedcapital 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 like the one we are currently experiencing could have an impact on the lenders participating in our credit facilities or on our customers, causing them to fail to meet their obligations to us.

Our internally generated cash flows are directlyDebt exchange litigation and purported notice of default—Prior to the consummation of the Exchange Transactions, we completed the Internal Reorganization.  In September 2020, funds managed by, or affiliated with Whitebox as holders of certain series of our notes subject to the Exchange Offers, filed the Claim in the Court related to our businessthe Internal Reorganization and the market sectorsExchange Offers.  Additionally, in September and October 2020, Whitebox and funds managed by, or affiliated with, PIMCO as debtholders, together with certain other advisors and debtholders, provided purported notices of alleged default with respect to the indentures governing, respectively, the 8.00% Guaranteed Notes and the 7.25% Guaranteed Notes.

On September 23, 2020, we filed an answer to the Claim with the Court and asserted counterclaims seeking a declaratory judgment that, among other matters, the Internal Reorganization did not cause a default under the indenture governing the 8.00% Guaranteed Notes.  Concurrently, with our answer and counterclaims, we also submitted a motion for summary judgment seeking an expedited judgment on our request for declaratory judgment.  Whitebox subsequently submitted a cross-motion for summary judgment seeking dismissal of our counterclaims.  On November 30, 2020, while awaiting the Court’s ruling on our motion for summary judgment, we amended certain of our financing documents and implemented certain internal reorganization transactions, which resolved the allegations contained in the purported notices of default.  On December 17, 2020, the Court issued its ruling granting our motion for summary judgment and denying the plaintiff’s cross-motion for summary judgment, holding, among other matters, that the allegations contained in the purported notice of default did not constitute a default under the indenture governing the 8.00% Guaranteed Notes.  Whitebox has appealed the Court’s ruling.

The facts alleged in the purported notice of default under the 8.00% Guaranteed Notes were the same as the facts underlying the Claim and the purported notice of default under the 7.25% Guaranteed Notes.  Accordingly, following the amendment and internal reorganization transactions on November 30, 2020, and the subsequent ruling from the Court granting our motion for summary judgment, we operate.  Ifdo not expect the liability, if any, resulting from these matters to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

Debt exchanges—On August 14, 2020, we issued $238 million aggregate principal amount of Senior Guaranteed Exchangeable Bonds in the Private Exchange for $397 million aggregate principal amount of the Exchangeable Senior Bonds.  The Senior Guaranteed Exchangeable Bonds are fully and unconditionally guaranteed by Transocean Ltd. and certain wholly owned indirect subsidiaries of Transocean Inc.  We may redeem all or a portion of the Senior Guaranteed Exchangeable Bonds (i) on or after August 14, 2022, if certain conditions related to the price of our shares have been satisfied, at a price equal to 100 percent of the aggregate principal amount and (ii) on or after August 14, 2023, at specified redemption prices.  The indenture that governs the Senior Guaranteed Exchangeable Bonds contains covenants that, among other things, limit our ability to incur certain liens on our drilling market wereunits without equally and ratably securing the notes,

On September 11, 2020, we issued $687 million aggregate principal amount of the 11.50% Senior Guaranteed Notes in the Exchange Offers, pursuant to an exchange offer memorandum, dated August 10, 2020, as supplemented, for an aggregate principal amount of $1.5 billion of several series of our existing debt securities that were validly tendered and expect that such cash flows will continue to be positive over the next year.

Business combinations—On December 5, 2018, we acquired Ocean Rig in a merger transaction,accepted for purchase.  The 11.50% Senior Guaranteed Notes are fully and as a result, Ocean Rig became ourunconditionally guaranteed by Transocean Ltd. and certain wholly owned subsidiary.  To completeindirect subsidiaries of Transocean Inc.  We may redeem all or a portion of the acquisition,11.50% Senior Guaranteed Notes prior to July 30, 2023 at a price equal to 100 percent of the aggregate principal amount plus a make-whole premium, and subsequently, at specified redemption prices.  We may also use the net cash proceeds of certain equity offerings by Transocean Ltd. to redeem, on one or more occasions prior to July 30, 2023, up to a maximum of 40 percent of the original aggregate principal amount of the 11.50% Senior Guaranteed Notes, subject to certain adjustments, at a redemption price equal to 111.50 percent of the aggregate principal amount.  The indenture that governs the 11.50% Senior Guaranteed 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, make certain internal transfers of our drilling units and consolidate, merge or enter into a scheme of arrangement qualifying as an amalgamation.

On February 26, 2021, we issued 147.7completed privately negotiated transactions to exchange $323 million sharesaggregate principal amount of outstanding Exchangeable Senior Bonds for $294 million aggregate principal amount of the New Senior Guaranteed Exchangeable Bonds and made an aggregate cash payment of $1.2 billion.

On January 30, 2018, we acquired an approximate 97.7 percent ownership interest in Songa.  On March 28, 2018, we acquired the remaining shares not owned by us through a compulsory acquisition under Cyprus law, and as a result, Songa became our wholly owned subsidiary.  To complete these transactions, we issued 68.0 million shares and issued $863 million aggregate principal amount of$11 million.  The New Senior Guaranteed Exchangeable Bonds as further described below.are guaranteed by Transocean Ltd. and the same subsidiaries of Transocean Inc. that guarantee the Senior Guaranteed Exchangeable Bonds and 11.50% Senior Guaranteed Notes.  In addition, the New Senior Guaranteed Exchangeable Bonds have an initial exchange rate of 190.4762 Transocean Ltd. shares per $1,000 note, which implies a conversion price of $5.25 per share, subject to adjustment upon the occurrence of certain events.

Secured Credit FacilityIn June 2018,As of December 31, 2020, we entered intohave a bank credit agreement, whichas amended from time to time, that established a $1.0our $1.3 billion secured revolving credit facility (“Secured Credit Facility,Facility”), which is scheduled to expire on the earlier of (i) June 22, 2023 and (ii) if greater than $300 million aggregate principal amount of our 9.00% Senior Notes due July 2023 remain outstanding in April 2023, such date.2023.  The Secured Credit Facility is guaranteed by Transocean Ltd. and certain subsidiaries.  The Secured Credit Facility is initially secured by, among other things, a lien on the ultra‑deepwaterultra-deepwater floaters Deepwater Asgard, Deepwater Corcovado, Deepwater Invictus, Deepwater Mykonos, Deepwater Orion, Deepwater Skyros, Development Driller III, Dhirubhai Deepwater KG2 and Discoverer Inspiration and the harsh environment floaters Transocean Barents and Transocean Spitsbergen.  The maximum borrowing capacity will be reduced to $1.0 billion if, and so long as, our leverage ratio, measured as the aggregate principal amount of debt outstanding to earnings before interest, taxes, depreciation and amortization, exceeds 10.00 to 1.00.  The Secured Credit Facility contains covenants that, among other things, include maintenance of certain guarantee and collateral coverage ratios, a maximum debt to capitalization ratio of 0.60 to 1.00 and minimum liquidity of $500 million.  The Secured Credit Facility also restricts the ability of Transocean Ltd. and certain of our subsidiaries to, among other things, merge, consolidate or otherwise make changes to the corporate structure, incur liens, incur additional indebtedness, enter into transactions with affiliates and pay dividends and other distributions.  In order to borrow under the Secured Credit Facility, we must, at

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.

Critical Accounting Policies and Estimates

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

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

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

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

Unrecognized tax benefits—We establish liabilities for estimated tax exposures, 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.interest and penalties.  Such tax exposures include potential challenges to permanent establishment positions, intercompany pricing, disposition transactions, and withholding tax rates and their applicability.  These exposures may be affected by changes in applicable tax law or other factors, which could cause us to revise our prior estimates, and are generally resolved through the settlement of audits within these tax jurisdictions or by judicial means.  At December 31, 20182020 and 2017, the liability for estimated2019, our unrecognized tax exposures in our jurisdictions of operation wasbenefits were approximately $514$419 million and $309$369 million, respectively.

Valuation allowanceWe are currently undergoing examinations in a number of taxing jurisdictions for various fiscal years.  We reviewapply significant judgment to determine whether our liabilities on an ongoing basis and, to the extent audits or other events cause us to adjust the liabilities accrued in prior periods, we recognize those adjustments in the period of the event.  We do not believe it is possible to reasonably estimate the future impact of changes to the assumptions and estimates related to our annual tax provision because changes to our tax liabilities are dependent on numerous factors that cannot be reasonably projected.  These factors include, among others, the amount and nature of additional taxes potentially asserted by local tax authorities; the willingness of local tax authorities to negotiate a fair settlement through an administrative process; the impartiality of the local courts; and the potential for changes in the taxes paid to one country that either produce, or fail to produce, offsetting tax changes in other countries.

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

Estimates, judgments and assumptions are required in determining whether deferred tax assets will be fully or partially realized.  In evaluating our abilityOur evaluation requires us 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 continually evaluate strategies that could allow for the future utilization of our deferred tax assets.  When it is estimated to be more likely than not that all or some portion of certain deferred tax assets, such as foreign tax credit carryovers or net operating loss carryforwards, will not be realized, we establish a valuation allowance for the amount of the deferred tax assets that is considered to be unrealizable.

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

We continually evaluate strategies that could allow for the future utilization of our deferred tax assets.  During the years ended December 31, 20182020 and 2017,2019, in evaluatingconnection with our evaluation of the projected realizability of our deferred tax assets, we considereddetermined that our consolidated cumulative

Unremitted earnings—We recognize deferred taxes related to the earnings of certain subsidiaries that we do not consider to be indefinitely reinvested or do not expect to be indefinitely reinvested in the future.  We do not provide for taxes on unremitted earnings of subsidiaries when we consider such earnings to be indefinitely reinvested.  If we were to make a distribution from the unremitted earnings of subsidiaries with indefinitely reinvested earnings, we may be subject to taxes payable to various jurisdictions.  If we were to change our expectations about distributing earnings of these subsidiaries, we may be required to record additional deferred taxes that could have a material effect on our consolidated financial statements.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes.

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

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

Property andrelated equipment,—The carrying amount of property and equipment is subject to various estimates, assumptions, and judgments related to capitalized costs,estimates and assumptions for cost capitalization, useful lives and salvage values and impairments.values.  At

- 38 -

December 31, 20182020 and 2017,2019, the carrying amount of our property and equipment was $20.4$17.7 billion and $17.4$18.8 billion, respectively, representing 8081 percent and 78 percent, respectively, of our total assets.

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

Useful lives and salvage values—We depreciate our assets using the straight‑linestraight-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, weWe may also consider major capital upgrades required to perform certain contracts and the long‑termlong-term impact of those upgrades on future marketability.  At December 31, 2018,2020, a hypothetical one‑yearone-year increase in the useful lives of all of our rigs would cause a decrease in our annual depreciation expense of approximately $40$27 million and a hypothetical one‑yearone-year decrease would cause an increase in our annual depreciation expense of approximately $64$35 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.recoverable.  Potential impairment indicators include rapid declines in commodity prices and related market conditions, declines in dayrates or utilization, cancellations of contracts or credit concerns of multiple customers.  During periods of oversupply, we may idle or stack rigs for extended periods of time or we may elect to sell certain rigs for scrap, which could be an indication that an asset group may be impaired since supply and demand are the key drivers of rig utilization and our ability to contract our rigs at economical rates.  Our rigs are mobile units, equipped to operate in geographic regions throughout the world and, consequently, we may movemobilize rigs from an oversupplied market sectorregion to a more lucrative and undersupplied market sectorregion 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‑deepwaterultra-deepwater floaters and harsh environment floaters and midwater floaters.

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

-  43  -


amount by which the carrying amount of the asset group exceeds its estimated fair value.  To estimate the fair value of each asset group, we apply a variety of valuation methods, incorporating income, market and cost approaches.  We may weigh the approaches, under certain circumstances, when relevant data is limited, when results are inconclusive or when results deviate significantly.  Our estimate of fair value generally requires us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the long-term future performance of our asset groups, such as projected revenues and costs, dayrates, rig utilization and revenue efficiency.  These projections involve uncertainties that rely on assumptions about demand for our services, future market conditions and technological developments.  Because our business is cyclical in nature, the results of our impairment testing are expected to vary significantly depending on the timing of the assessment relative to the business cycle.  Altering either the timing of or the assumptions used to estimate fair value and significant unanticipated changes to the assumptions could materially alter an outcome that could otherwise result in an impairment loss.  Given the nature of these evaluations and their application to specific asset groups and specific time periods, it is not possible to reasonably quantify the impact of changes in these assumptions.

In the year ended December 31, 2017,2020, we recognized a loss of $94 million ($93 million, net of tax) associated with the impairment of the midwater floater asset group.  In the year ended December 31, 2016, we recognized a loss of $52$31 million, which had no tax effect, associated with the impairment of the deepwatermidwater floater asset group.  In the years ended December 31, 2018, 2017 and 2016, we recognized a loss of $999 million, $1.4 billion and $41 million, respectively, associated with the impairment of assets that we determined were impaired at the time we classified such assets as assets held for sale.  See Notes to Consolidated Financial Statements—Note 6—Drilling Fleet.

Contingencies

Equity-method investments and impairment—We perform assessmentsreview our equity-method investments for potential impairment when events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable in the near term.  Such circumstances include the following: (a) evidence we are unable to recover the carrying amount of our investment, (b) evidence that the investee is unable to sustain earnings that would justify the carrying amount or (c) the current fair value of the investment is less than the carrying amount.  If an evaluation of such circumstances results in the determination that an impairment that is other than temporary exists, we recognize an impairment loss, measured as the amount by which the carrying amount of the investment exceeds its estimated fair value.  To estimate the fair value of the investment, we apply valuation methods that rely primarily on the income and market approaches.  Our estimate of fair value generally requires us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the estimated discount rate and the investee’s long-term future operational performance factors, such as projected revenues and costs and market factors, including demand for the investee’s industry, services and product lines.  Such projections involve significant uncertainties and require significant judgment.  In the year ended December 31, 2020, we recognized a loss of $59 million associated with an other-than-temporary impairment of the carrying amount of our equity-method investments.  See Notes to Consolidated Financial Statements—Note 4—Unconsolidated Affiliates.

- 39 -

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

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

Goodwill impairmentOther Matters

Regulatory matters

We conduct impairment testing foroccasionally receive inquiries from governmental regulatory agencies regarding our goodwill annually as of October 1operations around the world, including inquiries with respect to various tax, environmental, regulatory and more frequently, on an interim basis, when an event occurs orcompliance matters.  To the extent appropriate under the circumstances, change that may indicate a reduction in the fair value of a reporting unit is below its carrying amount.  Before testing goodwill, we consider whether or notinvestigate such matters, respond to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amountsuch inquiries and whether an impairment test is required.  If, as the result of our qualitative assessment, we determine that an impairment test is required, or, alternatively, if we elect to forgo the qualitative assessment, we test goodwill for impairment by comparing the carrying amount of the reporting unit, including goodwill, to the fair value of the reporting unit.  We test goodwill at the reporting unit level, which is defined as an operating segment or a component of an operating segment that constitutes a business for which financial information is available and is regularly reviewed by management.  We have determined that contract drilling services is our single reporting unit for this purpose.

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

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

Accounting Standards Updates

For a discussiontax 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 new accounting standards updates that have had or are expectedeffect, if any, resulting from these adjustments to have ana material adverse effect on our consolidated financial statements, seeposition, results of operations or cash flows.  We file federal and local tax returns in several jurisdictions throughout the world.  Tax authorities in certain jurisdictions are examining our tax returns and in some cases have issued assessments.  We are defending our tax positions in those jurisdictions.  While we cannot predict or provide assurance as to the final outcome of these proceedings, we do not expect the ultimate liability to have a material adverse effect on our consolidated financial position or results of operations, although it may have a material adverse effect on our consolidated cash flows.  See Notes to Consolidated Financial Statements—Note 3—Accounting Standards Updates.10—Income Taxes.

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

Item 8.Financial Statements and Supplementary Data

Management’s Report on Internal Control Over Financial Reporting

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

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a‑15(e)13a-15(e) and 15d‑15(e)15d-15(e) under the Securities Exchange Act of 1934.  Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2018.2020.  In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, as described in Internal Control‑IntegratedControl-Integrated Framework, as published in 2013.  On December 5, 2018, we completed our acquisition of Ocean Rig UDW Inc. (“Ocean Rig”).  Management has excluded Ocean Rig, which accounted for 11 percent of the Company’s total assets as of December 31, 2018, from its assessment of the effectiveness of the Company’s internal control over financial reporting.  Based on this assessment, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2018.2020.

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

Report of Independent Registered Public Accounting Firm

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

Opinion on Internal Control over Financial Reporting

We have audited Transocean Ltd. and subsidiaries’ internal control over financial reporting as of December 31, 2018,2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria).  In our opinion, Transocean Ltd. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018,2020, based on the COSO criteria.

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

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 20182020 and 2017,2019, and the related consolidated statements of operations, comprehensive income (loss),loss, equity and cash flows for each of the three years in the period ended December 31, 2018,2020, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 19, 2019,26, 2021, expressed an unqualified opinion thereon.

Basis for Opinion

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

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

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

Definition and Limitations of Internal Control Over Financial Reporting

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

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

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Transocean Ltd. and subsidiaries (the Company) as of December 31, 20182020 and 2017,2019, the related consolidated statements of operations, comprehensive income (loss),loss, equity and cash flows for each of the three years in the period ended December 31, 2018,2020, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the consolidated financial statements).  In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 20182020 and 2017,2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018,2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018,2020, based on criteria established in Internal Control—IntegratedControl-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 19, 201926, 2021, expressed an unqualified opinion thereon.

Basis for Opinion

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

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

Critical Audit Matters

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

Income Taxes

Description of the Matter

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

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

- 43 -

How We Addressed the Matter in Our Audit

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

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

Equity-Method Investment in Orion Holdings (Cayman) Limited

Description of the Matter

As discussed in Note 4, the Company recorded an impairment loss of $59 million associated with its equity-method investment in Orion Holdings (Cayman) Limited (Orion) upon determination that the carrying amount of its investment exceeded the estimated fair value and that the impairment was other than temporary.  At December 31, 2020, the aggregate carrying amount of the Company’s equity-method investment in Orion was $104 million.

Auditing management’s equity-method investment valuation was complex and judgmental due to the estimation required in determining the fair value of the investment.  In particular, the fair value estimate of the equity method investment in Orion was sensitive to significant assumptions such as the discount rate, future demand and supply of harsh environment floaters, rig utilization, revenue efficiency and dayrates.

How We Addressed the Matter in Our Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s process to determine the fair value of the investment in Orion.  For example, we tested management’s review controls over the significant assumptions described above as well as over the underlying data used in the fair value determination.

To test the estimated fair value of the Company’s equity-method investment in Orion, we performed audit procedures that included, among others, assessing the valuation methodologies utilized by management and testing the significant assumptions discussed above and the completeness and accuracy of the underlying data used by the Company in its analysis.  We involved a valuation specialist to assist in our evaluation of the Company's model, valuation methodology and significant assumptions.  We reviewed for contrary evidence related to the determination of the fair value of the equity-method investment, including reviewing relevant market data and internal Company forecasts.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Business

OverviewTransocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells.  We specialize in technically demanding sectors of the offshore drilling business with a particular focus on ultra‑deepwaterultra-deepwater and harsh environment drilling services.  Our mobile offshore drilling fleet is considered one of the most versatile fleets in the world.  We contract our drilling rigs, related equipment and work crews predominantly on a dayrate basis to drill oil and gas wells.  As of December 31, 2018,2020, we owned or had partial ownership interests in and operated a fleet of 5038 mobile offshore drilling units, including 32 ultra‑deepwater floaters, 14 harsh environment27 ultra-deepwater floaters and four midwater11 harsh environment floaters.  As of December 31, 2018,2020, we were constructing (i) four additional ultra‑deepwater drillships and (ii) one additional harsh environment semisubmersible, in which we hold a partial ownership interest.2 ultra-deepwater drillships.

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

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

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

Note 2—Significant Accounting Policies

Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted in the United States (“U.S.”), we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities.  On an ongoing basis, we evaluate our estimates and assumptions, including those related to our allowance for doubtful accounts, materials and supplies obsolescence,income taxes, property and equipment, equity investments, contingencies, assets held for sale, goodwill, income taxes, contingencies, share‑based compensationintangibles, allowance for excess materials and supplies, allowance for credit losses, postemployment benefit plans.plans, leases and share-based compensation.  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‑levelthree-level hierarchy, from highest to lowest level of observable inputs, as follows: (1) significant observable inputs, including unadjusted quoted prices for identical assets or liabilities in active markets (“Level 1”), (2) significant other observable inputs, including direct or indirect market data for similar assets or liabilities in active markets or identical assets or liabilities in less active markets (“Level 2”) and (3) significant unobservable inputs, including those that require considerable judgment for which there is little or no market data (“Level 3”).  When a valuation requires multiple input levels, we categorize the entire fair value measurement according to the lowest level of input that is significant to the measurement even though we may have also utilized significant inputs that are more readily observable.

Consolidation—We consolidate entities in which we have a majority voting interest and entities that meet the criteria for variable interest entities for which we are deemed to be the primary beneficiary for accounting purposes.  We eliminate intercompany transactions and accounts in consolidation.  We apply the equity method of accounting for an equity investment in an unconsolidated entity if we have the ability to exercise significant influence over the entity that (a) does not meet the variable interest entity criteria or (b) meets the variable interest entity criteria, but for which we are not deemed to be the primary beneficiary.  We applymeasure other equity investments at fair value if the investment has a fair value that is readily determinable; otherwise, we measure the investment at 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.less any impairment.  We separately present

within equity on our consolidated balance sheets the ownership interests attributable to parties with noncontrolling interests in our consolidated subsidiaries, and we separately present net income attributable to such parties on our consolidated statements of operations.  See Note 4—Unconsolidated Affiliates and Note 14—Equity.Equity.

Business combinationsIn connection with our acquisitions, we appliedWe apply the acquisition method of accounting.  Accordingly,accounting for business combinations, under which we recordedrecord the acquired assets and assumed liabilities at fair value and recognizedrecognize goodwill to the extent the consideration transferred exceededexceeds the fair value of the net assets acquired.  To the extent the fair value of the net assets acquired exceededexceeds the consideration transferred, we recognize a bargain purchase gain, recorded in other income, net.gain.  We estimatedestimate the fair values of the acquired assets and assumed liabilities as of the date of the acquisition, and our estimates are subject to adjustment through completion, which is in each case within one year of the acquisition date, based on our ongoing assessments of the fair values of property and equipment, intangible assets, other assets and liabilities and our evaluation of tax positions and contingencies, which are ongoing.  We will complete our final assessments of the fair values of the acquired assets and assumed liabilities and our final evaluations of uncertain tax positions and contingencies within one year of the acquisition date.contingencies.  See Note 4—3—Business Combinations.

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

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

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

Revenue recognition—We recognize revenues earned under our drilling contracts based on variable dayrates, which range from a full operating dayrate to lower rates or zero rates for periods when drilling operations are interrupted or restricted, based on the specific activities we perform during the contract on an hourly, or more frequent, basis.  Such dayrate consideration is attributed to the distinct time period to which it relates within the contract term, and therefore, is recognized as we perform the services.  When the operating dayrate declines over the contract term, we recognize revenues on a straight‑linestraight-line basis over the fullestimated contract period.  We recognize reimbursement revenues and the corresponding costs as we provide the customer‑requestedcustomer-requested goods and services, when such reimbursable costs are incurred while performing drilling operations.  Prior to performing drilling operations, we may receive pre‑operatingpre-operating revenues, on either a fixed lump‑sumlump-sum or variable dayrate basis, for mobilization, contract preparation, customer‑requestedcustomer-requested goods and services or capital upgrades, which we recognize on a straight‑linestraight-line basis over the estimated firm contract period.  We recognize losses for loss contracts as such losses are incurred.  We recognize revenues for demobilization orover the contract period unless otherwise constrained.  We recognize revenues from contract terminations as we fulfill our obligations and all contingencies have been resolved.  To obtain contracts with our customers, we incur costs to prepare a rig for contract and deliver or mobilize a rig to the drilling location.  We defer pre‑operatingpre-operating costs, such as contract preparation and mobilization costs, and recognize such costs on a straight‑linestraight-line basis, consistent with the general pace of activity, in

Sharebased compensation—To measure the fair values of granted or modified stock options, we use the Black‑Scholes‑Merton option‑pricing model and apply assumptions for the expected life, risk‑free interest rate, expected volatility and dividend yield.  To measure the fair values of granted or modified service‑basedservice-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‑basedstock options, we use the Black-Scholes-Merton option-pricing model and apply assumptions for the expected life, risk-free interest rate, expected volatility and dividend yield.  To measure the fair values of granted or modified performance-based restricted share units subject to market factors, we use a Monte Carlo simulation model and, in addition to the assumptions applied for the Black‑Scholes‑Merton option‑pricingBlack-Scholes-Merton option-pricing model, we use a risk neutral approach and an average price at the performance start date.  We recognize share‑basedshare-based compensation expense in the same financial statement line item as cash compensation paid to the respective employees or non‑employeenon-employee directors.  We recognize such compensation expense on a straight‑linestraight-line basis over the service period through the date the employee or non‑employeenon-employee director is no longer required to provide service to earn the award.  In the years ended December 31, 2018, 2017 and 2016, share‑based compensation expense was $45 million, $41 million and $42 million, respectively.  See Note 15—Share BasedShare-Based Compensation Plans.

Capitalized interest—We capitalize interest costs for qualifying construction and upgrade projects and only capitalize interest costs during periods in which progress for the construction projects continues to be underway.  In the years ended December 31, 2018, 20172020, 2019 and 2016,2018, we capitalized interest costs of $37$47 million, $116$38 million and $176$37 million, respectively, for our construction work in progress.

Functional currency—We consider the U.S. dollar to be the functional currency for all of our operations since the majority of our revenues and expenditures are denominated in U.S. dollars, which limits our exposure to currency exchange rate fluctuations.  We recognize currency exchange rate gains and losses in other, net.  In the years ended December 31, 2018, 20172020, 2019 and 2016,2018, we recognized a net loss of $38$8 million, a net lossgain of $6$2 million and a net loss of $2$38 million, respectively, related to currency exchange rates.

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

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

We maintain liabilities for estimated tax exposures in our jurisdictions of operation, and we recognize the provisions and benefits resulting from changes to those liabilities in our income tax expense or benefit along with related interest and penalties.  TaxIncome tax exposure items include potential challenges to permanent establishment positions, intercompany pricing, disposition transactions, and withholding tax rates and their applicability.  These tax exposures are resolved primarily through the settlement of audits within these tax jurisdictions or by judicial means, but can also be affected by changes in applicable tax law or other factors, which could cause us to revise past estimates.  See Note 10—Income Taxes.

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

Short‑term investments—We periodically deposit unrestricted excess funds in time deposits and commercial paper with original maturities beyond three months.  Such short‑term investments are with commercial banks with high credit ratings.

Accounts receivable—We earn our revenues by providing our drilling services to internationalthree major categories of customers: (a) integrated oil companies, (b) government-owned or government-controlled oil companies and government‑owned or government‑controlled(c) other independent oil companies.  We evaluateEffective January 1, 2020, we adopted the accounting standards update that requires entities to estimate an expected lifetime credit quality of our customersloss on an ongoing basis, andfinancial assets ranging from short-term trade accounts receivable to long-term financings without retrospective application.  Accordingly, we may occasionally require collateral or other security to support customer receivables.  We establish an allowance for doubtful accountscredit losses based on a case‑by‑casethe loss rate method, considering forecasted future conditions in addition to past events and current conditions for our customers in each of the major categories and on an individual basis considering changes inwhen the financial positionrisk characteristics of a customer, when we believean account are no longer representative of the required payment of specific amounts owedcategory to us is unlikely to occur.which it otherwise belongs.  At December 31, 2018 and 2017, the2020, our allowance for doubtful accountscredit losses was less than $1$2 million.

Restricted cash accounts and investmentscash equivalents—We maintain restricted cash accounts and investmentscash equivalents that are either pledged for debt service under certain bond indentures, as required under certain bank credit arrangements, or held in accounts that are subject to restrictions due to legislation, regulation or court order.  We classify such restricted cash accounts and investmentscash equivalents in current assets if the restriction is expected to expire or otherwise be resolved within one year or if such funds are considered to offset liabilities that are properly classified as current liabilities. At December 31, 2018, the aggregate carrying amount of our restricted cash accounts and investments was $552 million, of which $551 million and $1 million was classified in current assets and other assets, respectively.  At December 31, 2017, the aggregate carrying amount of our restricted cash accounts and investments was $489 million, of which $466 million and $23 million was classified in current assets and other assets, respectively. See Note 3—Accounting Standards Updates, Note 8—9—Debt and Note 13—Commitments and Contingencies and Note 18—Financial Instruments.Contingencies.

Assets held for sale—We classify an asset as held for sale when the facts and circumstances meet the criteria for such classification, including the following: (a) we have committed to a plan to sell the asset, (b) the asset is available for immediate sale, (c) we have initiated actions to complete the sale, including locating a buyer, (d) the sale is expected to be completed within one year, (e) the asset is being actively marketed at a price that is reasonable relative to its fair value, and (f) the plan to sell is unlikely to be subject to significant changes or termination.  At December 31, 20182020 and 2017, the aggregate carrying amount of our2019, we had 0 assets classified as held for sale, recorded in other current assets, was $25 million and $22 million, respectively.  See Note 6—Drilling Fleet.sale.

Property and equipmentThe carrying amounts ofWe apply judgment to account for our property and equipment, consisting primarily of offshore drilling rigs and related equipment, are based on ourrelated to estimates and assumptions and judgments relative to capitalized costs,for cost capitalization, useful lives and salvage values ofvalues.  We base our rigs.  These estimates and assumptions and judgments reflect bothon historical experience and expectations regarding future industry conditions and operations.  At December 31, 2018,2020, the aggregate carrying amount of our property and equipment represented approximately 8081 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‑linestraight-line method after allowing for salvage values.

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

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

Equity investments and impairment—We review our equity-method investments, and other equity investments for which a readily determinable fair value is not available, for potential impairment when events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable in the near term.  If we determine that an impairment that is other than temporary exists, we recognize an impairment loss, measured as the amount by which the carrying amount of the investment exceeds its estimated fair value.  To estimate the fair value of the investment, we apply valuation methods that rely primarily on the income and market approaches.  In the year ended December 31, 2020, we recognized a loss of $62 million associated with the other-than-temporary impairment of the carrying amount of our equity investments. See Note 4—Unconsolidated Affiliates.

Goodwill—We conduct impairment testing for goodwill annually as of October 1 and more frequently, on an interim basis, when an event occurs or circumstances change that indicate that the fair value of our reporting unit may have declined below its carrying amount.  In the year ended December 31, 2018, as a result of an interim goodwill test, we recognized an aggregate loss of $462 million, which had 0 tax effect, associated with the impairment of the full balance of our goodwill.  See Note 3—Business Combinations and Note 7—Goodwill and Other Intangibles.

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

drilling revenues over the expected remaining contract period.  At December 31, 2020 and 2019, the aggregate carrying amount of our drilling contract intangible assets was $393 million and $608 million, respectively.  See Note 3—Business Combinations and Note 7—Goodwill and Other Intangibles.

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

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

At December 31, 20182020 and 2017,2019, our pension and other postemployment benefit plan obligations represented an aggregate liability of $362$277 million and $359$351 million, respectively, and an aggregate asset of $47$37 million and $17$42 million, respectively, representing the funded status of the plans.  In the years ended December 31, 2018, 2017 and 2016, aggregate net periodic benefit costs were income of $9 million, costs of $5 million and income of $11 million, respectively.  See Note 3—Accounting Standards Updates and Note 12—Postemployment Benefit Plans.

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

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

Note 3—Accounting Standards Updates

Recently adopted accounting standards

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

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

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

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

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

Recently issued accounting standards

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

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

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

Note 4—Business Combinations

Overview

During the year ended December 31, 2018, we completed the acquisitions of Songa Offshore SE (“Songa”), a European public company limited by shares, or societas Europaea, existing under the laws of Cyprus, and Ocean Rig.Rig UDW Inc. (“Ocean Rig”), a Cayman Islands exempted company with limited liability.  On January 30, 2018, we acquired an approximate 97.7 percent ownership interest in Songa.  We believe the Songa acquisition strengthens our position as a leader in harsh environment and ultra‑deepwater drilling services by adding high value assets, including four high‑specification harsh environment floaters, supported by significant contract backlog, and strengthens our footprint in harsh environment operating areas.  The goodwill resulting from the business combination was attributed to synergies and intangible assets that did not qualify for separate recognition.  On December 5, 2018, we acquired Ocean Rig in a merger transaction.  We believe the Ocean Rig acquisitionboth acquisitions further strengthensstrengthen our position as a leader in the ultra‑deepwaterproviding ultra-deepwater and harsh environment drilling services by adding additional high‑valuehigh-value assets, including nine ultra‑deepwater floaters and twowe believe the Songa acquisition, supported by significant contract backlog, also strengthens our footprint in harsh environment floaters, and the contracts relating to the construction of two ultra‑deepwater drillships (see Note 22—Subsequent Events).operating areas.  In the year ended December 31, 2018, and 2017, in connection with these acquisitions, we incurred acquisition costs of $24 million, and $4 million, respectively, recorded in general and administrative costs and expenses.

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

We estimated the fair value of the rigs and related equipment by applying a combination of income and market approaches, using projected discounted cash flows and estimates of the exchange price that would be received for the assets in the principal or most advantageous markets for the assets in an orderly transaction between participants as of the acquisition date.  We estimated the fair value

of the drilling contracts by comparing the contractual dayrates over the remaining firm contract term and option periods relative to the projected market dayrates as of the acquisition date.  We estimated the fair value of the construction contracts by comparing the contractual future payments and terms relative to the market payments and terms as of the acquisition date.  Our estimates of fair value for the drilling units and contract intangibles required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of the assets, such as future commodity prices, projected demand for our services, rig availability, rig utilization, dayrates, remaining useful lives of the rigs and discount rates.

We have not completed our estimatesIn connection with the Ocean Rig acquisition, we acquired contracts with Samsung Heavy Industries Co., Ltd. (“SHI”) for the construction of 2 ultra-deepwater drillships for which we recognized liabilities that represented the amount by which the remaining payments due under the acquired contracts were above market construction rates for similar drilling units, measured as of the fair values of assets acquiredacquisition date.  In October 2019, we agreed with SHI to cancel the construction contracts for the drillships in exchange for the parties terminating their respective obligations and liabilities assumed.  We continueunder the construction contracts and our subsidiaries releasing to reviewSHI their respective interests in the estimated fair values of property and equipment, intangible assets, and other assets andrigs.  As a result, in the three months ended December 31, 2019, we eliminated the construction contract liabilities and to evaluate the assumed tax positions and contingencies.  Our estimatesrecognized income of the fair value for such assets and liabilities require significant assumptions and judgment.  Until we complete our evaluation, we may be required to adjust our original estimates, and such adjustments could be material.$132 million, recorded in other income, net.

In the year ended December 31, 2018, we completed our estimates of the fair values of the assets and liabilities.  We estimated the fair value of the rigs and related equipment by applying a combination of income and market approaches, using projected discounted cash flows and estimates of the exchange price that would be received for the assets in the principal or most advantageous markets for the assets in an orderly transaction between participants as of the acquisition date.  We estimated the fair value of the drilling contracts by comparing the contractual dayrates over the remaining firm contract term and option periods relative to the projected market dayrates as of the acquisition date.  The goodwill resulting from the business combination was attributed to synergies and intangible assets that did not qualify for separate recognition.  Our estimates of fair value for these assets required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of the assets, such as future commodity prices, projected demand for our services, rig availability, dayrates and discount rates.  We estimated the fair value of the debt using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments.

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

In connection with the Songa acquisition, we acquired undesignated currency swaps and interest rate swaps that we subsequently settled and terminated.  In the year ended December 31, 2018, in connection with the settlement of the currency swaps and the interest rate swaps, we made an aggregate cash payment of $92 million and received aggregate cash proceeds of $18 million, respectively.

Note 4—Unconsolidated Affiliates

Equity investments—We hold noncontrolling equity investments in various unconsolidated companies, including (a) our 33.0 percent ownership interest in Orion Holdings (Cayman) Limited (together with its subsidiary, “Orion”), a Cayman Islands company that, through its wholly owned subsidiary, owns the harsh environment floater Transocean Norge, and (b) our interests in certain companies that are involved in researching and developing technology to improve efficiency and reliability and to increase automation, sustainability and safety for drilling and other activities.  At December 31, 2020 and 2019, the aggregate carrying amount of our equity investments was $138 million and $191 million, respectively, recorded in other assets.

Our equity-method investment in Orion is the most significant of our equity investments.  In the years ended December 31, 2020, 2019 and 2018, we made an aggregate cash contribution of $8 million, $74 million and $91 million, respectively, to Orion, and we expect to make an additional $33 million cash contribution in the six months ending June 30, 2021.  In the year ended December 31, 2020, we recognized a loss of $59 million, which had no tax effect, recorded in other, net, associated with the impairment of our equity-method investment in Orion upon determination that the carrying amount exceeded the estimated fair value and that the impairment was other than temporary.  We estimated the fair value of our investment using the income method, which required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including applying an assumed discount rate of 12 percent and making assumptions

about the future performance of the investment, including future demand and supply for harsh environment floaters, rig utilization, revenue efficiency and dayrates.  At December 31, 2020 and 2019, the aggregate carrying amount of our investment in Orion was $104 million and $164 million, respectively.

Related party transactions—We engage in certain related party transactions with our unconsolidated affiliates, the most significant of which are under agreements with Orion.  We have a management services agreement for the operation and maintenance of the harsh environment floater Transocean Norge and a marketing services agreement for the marketing of the rig.  We also lease the rig under a short-term bareboat charter agreement, which is expected to expire in mid-2021.  Prior to the rig’s placement into service, we also engaged in certain related party transactions with Orion under a shipyard care agreement for the construction of the rig and other matters related to its completion and delivery.  Additionally, we procure services and equipment from other unconsolidated affiliates for technological innovation.

In the years ended December 31, 2020 and 2019, we received an aggregate cash payment of $46 million and $96 million, respectively, primarily related to the commissioning, preparation and mobilization of Transocean Norge under the shipyard care agreement with Orion.  In the years ended December 31, 2020 and 2019, we recognized rent expense of $22 million and $9 million, respectively, recorded in operating and maintenance costs, and made an aggregate cash payment of $22 million and $6 million, respectively, to charter the rig and other equipment from Orion.  In the years ended December 31, 2020 and 2019, we made an aggregate cash payment of $15 million and $11 million, respectively, to other unconsolidated affiliates for research and development and for equipment to reduce emissions and improve reliability.

Note 5—Revenues

OverviewThe services we perform represent a single performance obligation under our drilling contracts with customers that is satisfied over time.  We earn revenues primarily by performing the following activities: (i) providing our drilling rig, work crews, related equipment and services necessary to operate the rig (ii) delivering the drilling rig by mobilizing to and demobilizing from the drill location, and (iii) performing certain pre‑operatingpre-operating activities, including rig preparation activities or equipment modifications required for the contract.

The  These services represent a single performance obligation under our drilling contracts with customers that is satisfied over time, the duration of our performance obligationwhich varies by contract.  At December 31, 2018,2020, the drilling contract with the longest expected remaining duration, of our drilling contractsexcluding unexercised options, extends through February 2028, excluding unexercised options.2028.

In June 2020, we entered into a settlement and mutual release agreement with a customer, which provided for the final settlement of disputes related to performance obligations satisfied in prior periods.  In connection with the settlement, among other things, our customer agreed to pay us $185 million in four equal installments through January 15, 2023.  In the year ended December 31, 2020, we recognized revenues of $177 million, representing the discounted value of the future payments, and recorded corresponding accounts receivable, net of imputed interest.  In the year ended December 31, 2020, we received an aggregate cash payment of $46 million in scheduled installments under the arrangement.  At December 31, 2020, the aggregate carrying amount of the related receivable was $133 million, net of imputed interest, including $45 million and $88 million recorded in accounts receivable and other assets, respectively.

In the year ended December 31, 2019, we recognized revenues of $10 million for other performance obligations satisfied in previous periods due to certain revenues recognized on a cash basis.  In the year ended December 31, 2018, we recognized revenues of $174 million respectively, for yet other performance obligations satisfied in previous periods, primarily related to ourrevenues for a customer’s termination of the contract for Discoverer Clear Leader, effective November 2017,termination and certain revenues recognized on a cash basis.

To obtain contracts with our customers, we incur pre-operating costs to prepare a rig for contract and deliver or mobilize the rig to the drilling location.  We recognize such pre-operating costs in operating and maintenance costs on a straight-line basis, consistent with the general pace of activity, over the estimated contract period.  In the years ended December 31, 2018, 20172020, 2019 and 2016,2018, we recognized pre-operating costs of $60 million, $18 million and $45 million, $45 million and $86 million, respectively, associated with pre‑operating costs for contracts with customers.respectively.  At December 31, 20182020 and 2017,2019, the unrecognized pre‑operatingpre-operating costs to obtain contracts was $2$20 million and $18$34 million, respectively, recorded in other assets.

We measured the fair value of the drilling unit and related assets in this asset groupsgroup by applying a combination of income andthe market approaches,approach, using projected discounted cash flows and estimates of the exchange price that would be received for the assets in the principal or most advantageous markets for the assets in an orderly transaction between participants as of the measurement date.  Our estimate of fair value required us to use significant unobservableother observable inputs, representative of a Level 32 fair value measurement,measurements, including assumptions related to the future performancemarketability of our contract drilling services reporting unit, such as future commoditythe rig and 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, wecomparable rigs that 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.sold for scrap value.

Impairments of assets held for saleIn the year ended December 31, 2020, we recognized an aggregate loss of $556 million ($0.90 per diluted share), which had 0 tax effect, associated with the impairment of the ultra-deepwater floater GSF Development Driller II, the harsh environment floaters Polar Pioneer and Songa Dee and the midwater floaters Sedco 711, Sedco 714 and Transocean 712, along with related assets, which we determined were impaired at the time that we classified the assets as held for sale.  In the year ended December 31, 2019, we recognized an aggregate loss of $578 million ($0.94 per diluted share), which had 0 tax effect, associated with the impairment of the ultra-deepwater floaters Discoverer Deep Seas, Discoverer Enterprise and Discoverer Spirit, along with related assets, which we determined were impaired at the time we classified the assets as held for sale.  In the year ended December 31, 2018, we recognized an aggregate loss of $999 million ($2.13 per diluted share), which had no0 tax effect, associated with the impairment of the ultra‑deepwaterultra-deepwater floaters Deepwater Discovery, Deepwater Frontier, Deepwater Millennium and GSF C.R. Luigs, the deepwater floaters Jack Bates and Transocean 706 and the midwater floaters Songa Delta and Songa Trym, along with related assets, which we determined were impaired at the time that we classified the assets as assets held for sale.

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

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

We measured the impairment of the drilling units and related assets as the amount by which the carrying amount exceeded the estimated fair value less costs to sell.  We estimated the fair value of the assets using significant other observable inputs, representative of

Note 9—Derivative Instruments

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

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

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

Currency swaps—In connection with the Songa acquisition, we acquired currency swaps, which were previously designated as a cash flow hedge, to reduce the variability of cash interest payments and the final cash principal payment associated with the Bond Loans resulting from the changes in the U.S. dollar to Norwegian krone exchange rate.  On the acquisition date, the aggregate fair value of the currency swaps represented a liability of $81 million.  In February 2018, we made an aggregate cash payment of $92$375 million, $354 million and $257 million, respectively, to repay other indebtedness in connection with the settlement and termination of the currency swaps.  In the year ended December 31, 2018, we recognized a loss of $11 million, recorded in other, net, associated with the currency swaps.scheduled installments.

Note 10—Income Taxes

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

Tax provision and rate—Our provision for income taxes is based on the tax laws and rates applicable in the jurisdictions in which we operate and earn income.  In the years ended December 31, 2020, 2019 and 2018, our effective tax rate was (5.1) percent, (4.9) percent and (12.8) percent, respectively, based on loss before income tax expense.  The relationship between our provision for or benefit from income taxes and our income or loss before income taxes can vary significantly from period to period considering, among other factors, (a) the overall level of income before income taxes, (b) changes in the blend of income that is taxed based on gross revenues rather than income before taxes, (c) rig movements between taxing jurisdictions and (d) our rig operating structures.

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

In the year ended December 31, 2017, the U.S. introduced certain changes to tax law (“U.S. tax reform”), such as, among others, a transition tax and a base erosion and anti-abuse tax.  In the year ended December 31, 2018, to calculate the one-time transition tax, we completed the evaluation of our unremitted earnings and profits of certain of our non-U.S. subsidiaries that owned by U.S. subsidiaries for which the necessary information was not previously available, and we recorded income tax expense of $120 million for transition taxes, partially offset by $16 million for the utilization of estimated foreign tax credits.  In the years ended December 31, 2019 and 2018, we

At December 31, 20182020 and 2017,2019, our deferred tax assets included U.S. foreign tax credit carryforwards of $11$21 million and $37$22 million, respectively, which will expire between 20192024 and 2028.  The deferred2030.  Deferred tax assets related to our net operating losses were generated in various worldwide tax jurisdictions.  At December 31, 2018, the2020, our net deferred tax assets related to our net operating lossesloss carryforwards which were generated in various jurisdictions worldwide, included $307$572 million, thatwhich do not expire, and $172$237 million, thatwhich will expire beginning between 2021 and 2038.  At December 31, 2017, the net operating losses carryforwards, which were generated in various jurisdictions worldwide, included $261 million that do not expire and $174 million that will expire beginning between 2020 and 2037.

As of December 31, 2018,2020, our consolidated cumulative loss incurred over the recent three‑yearthree-year period was primarily due to losses on impairment and disposal of assets, which represented significant objective negative evidence for ourthe evaluation of the realizability of our deferred tax assets.  Although such evidence has limited our ability to consider other subjective evidence, we analyzeevaluate each jurisdiction separately.  We consider objective evidence, such as contract backlog activity, in jurisdictions in which we have profitable contracts.contracts, and the ability to carryback losses or utilize losses against potential exposures.  If estimated future taxable income changes during the carryforward periods or if the cumulative loss is no longer present, we may adjust the amount of deferred tax assets that we expect to realize.  At December 31, 20182020 and 2017,2019, due to uncertainty of realization, we have recordedhad a valuation allowance of $681$685 million and $574$716 million, respectively, on net operating losses and other deferred tax assets.

Our other deferred tax liabilities include taxes related to the earnings of certain subsidiaries that are not indefinitely reinvested or that will not be indefinitely reinvested in the future.  Wereinvested.  As of December 31, 2020, we consider the earnings of certain of our subsidiaries to be indefinitely reinvested.  As of December 31, 2018,reinvested, and we didhave not provideprovided for deferred taxes on earnings of certainsuch subsidiaries.  If we were to make a distribution from the unremitted earnings of subsidiaries that arewith indefinitely reinvested becauseearnings, we may be subject to taxes payable to various jurisdictions.  However, it is not practicalpracticable to estimate the amount of tax that would ultimately be due if remitted.  If we were to make a distribution from the unremittedchange our expectations about distributing earnings of these subsidiaries, we would be subject to taxes payable to various jurisdictions.  If our expectations were to change regarding

In the years ended December 31, 2018, 20172020, 2019 and 2016,2018, we recognized, as a component of our income tax provision, expense of $13$7 million, incomebenefit of $9$72 million and incomeexpense of $23$13 million, respectively, related to previously recognized interest and penalties associated with our unrecognized tax benefits.  As of December 31, 2018, if recognized, $5142020, we have unrecognized benefits of $419 million, including interest and penalties, of ourwhich $261 million are netted against net operating loss deferred tax assets resulting in net unrecognized tax benefits of $158 million, including interest and penalties, that upon reversal would favorably impact our effective tax rate.

It  During the year ending December 31, 2021, it is reasonably possible that our existing liabilities for unrecognized tax benefits may increase or decrease, in the year ending December 31, 2019, primarily due to the progression of open audits and the expiration of statutes of limitation.  However, we cannot reasonably estimate a range of potential changes in our existing liabilities for unrecognized tax benefits due to various uncertainties, such as the unresolved nature of various audits.

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

In the year ended December 31, 2017,  we recognized income tax expense of $66 million with a corresponding decrease to our net deferred tax assets to reflect the reduction in the U.S. corporate income tax rate from 35 percent to 21 percent.

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

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

Tax returns—We file federal and local tax returns in several jurisdictions throughout the world.  With few exceptions, we are no longer subject to examinations of our U.S. and non‑U.S.non-U.S. tax matters for years prior to 2011.2014.  Our tax returns in the majorsignificant jurisdictions in which we operate, other than Brazil, as mentioned below, are generally subject to examination for periods ranging from three to six years.  We have agreed to extensions beyond the statute of limitations in two major jurisdictions for up to 20 years.  Tax authorities in certain jurisdictions are examining our tax returns and, in some cases, have issued assessments.  We are defending our tax positions in those jurisdictions.  While we cannot predict or provide assurance as to the timing or the outcome of these proceedings, we do not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations, although it may have a material adverse effect on our consolidated statement of cash flows.

Brazil tax investigations—In December 2005, the Brazilian tax authorities began issuing tax assessments with respect to our tax returns for the years 2000 through 2004.  In January 25, 2008, we filed a protest letter with the Brazilian tax authorities for these tax assessments, and we are currently engaged in the appeals process.  In May 19, 2014, the Brazilian tax authorities issued an additional tax assessment for the years 2009 and 2010, and in June 18, 2014, we2010.  We filed protests with the Brazilian tax authorities for these tax assessments.  In Septemberthe assessments and are currently engaged in the appeals process.  During the years ended December 31, 2018 and 2019, a portion of one of thetwo cases waswere favorably closed.  As of December 31, 2018,2020, the remaining aggregate tax assessment, including interest and penalties, was for corporate income tax of BRL 973640 million, equivalent to approximately $251$123 million, including penalties and interest.indirect tax of BRL 95 million, equivalent to $18 million.  We believe our returns are materially correct as filed, and we are vigorously contesting these assessments.  An unfavorable outcome on these proposed assessments could result inhave a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

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

Defined contribution plans

We sponsor defined contribution plans for our employees in most markets in which we operate worldwide, the most significant of which were as follows: (1) a qualified savings plan covering certain eligible employees working in the U.S., (2) various savings plans covering eligible employees working in Norway, (3) a non-qualified savings plan covering certain eligible employees working outside the U.S., the U.K. and Norway and (4) a qualified savings plan covering certain eligible employees working in the U.K.  In the years ended December 31, 2020, 2019 and 2018, we recognized expense of $56 million, $52 million and $50 million, respectively, related to our defined contribution plans globally.

Defined benefit pension and other postemployment benefit plans

Overview—As of December 31, 2018,2020, we had defined benefit plans in the U.S., the United Kingdom (“U.K.”), and Norway.  Benefits under the defined benefit plans in the U.S. and the U.K.Norway, all of which have ceased accruing.  We maintain the respective pension obligations under such plans until they have been fully satisfied.

TRANSOCEAN LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

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, which are group pension schemes with life insurance companies, we establish minimum rates of return under the terms of the investment contracts with insurance companies.    As of December 31, 2018 and 2017, the weighted‑average target and actual allocations of thecontracts.

Legal proceedings

Macondo well incident—On April 22, 2010,Debt exchange litigation and purported notice of default—Prior to the ultra‑deepwater floater Deepwater Horizon sank after a blowoutconsummation of the Macondo well caused a fire and explosion on the rig off the coastExchange Transactions (see Note 9—Debt), we completed certain internal reorganization transactions (the “Internal Reorganization”).  In September 2020, funds managed by, or affiliated with, Whitebox Advisors LLC (“Whitebox”) as holders of Louisiana.  At the timecertain series of the explosion, Deepwater Horizon was contracted to an affiliate of BP plc. (together with its affiliates, “BP”).  Following the incident, we have beenour notes 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 toExchange Offers, filed a claim (the “Claim”) in the U.S. District Court for the EasternSouthern District of Louisiana (the “MDL Court”).  A significant portion of the contingencies arising from the Macondo well incident has now been resolved or is pending release of funds from escrow (see “—PSC Settlement Agreement”).  As for any actions not resolved by our previous settlements, including any claims by individuals who opted out of the settlement agreement that we and the Plaintiff Steering Committee (the “PSC”) filed with the MDL Court in May 2015 (the “PSC Settlement Agreement”), we will vigorously defend those claims and pursue any and all defenses available.

We recognized a liability for the remaining estimated loss contingencies associated with litigation resulting from the Macondo well incident that we believe are probable and for which a reasonable estimate can be made.  At December 31, 2018 and 2017, the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $158 million and $219 million, respectively, recorded in other current liabilities, the majority of which is related to our settlement with the PSC.

PSC Settlement Agreement—On May 29, 2015, together with the PSC, we filed the PSC Settlement Agreement with the MDL Court for approval.  Through the PSC Settlement Agreement, we agreed to pay a total of $212million, plus up to $25 million for partial reimbursement of attorneys’ fees, to be allocated between two classes of plaintiffs as follows: (1) 72.8 percent to private plaintiffs, businesses, and local governments who could have asserted punitive damages claims against us under general maritime law; and (2) 27.2 percent to private plaintiffs who previously settled economic damages claims against BP and were assigned certain claims BP had made against us.  In exchange for these payments, each of the classes agreed to release all respective claims it has against us.  Thirty claimants elected to opt out of the PSC Settlement Agreement.  In June 2016 and August 2015, we made a cash deposit of $25 million and $212 million, respectively, into an escrow account established by the MDL Court for the settlement.  On February 15, 2017, the MDL Court entered a final order and judgement approving the PSC Settlement Agreement, which is no longer subject to appeal.  In November 2017, the MDL Court released $25 million from the escrow account for payment of attorneys’ fees.  In November 2018, the MDL Court released $58 million from the escrow account as the first installment to the plaintiffs.  At December 31, 2018 and 2017, the aggregate cash balance in escrow account was $156 million and $212 million, respectively, recorded in restricted cash accounts and investments.  We expect the remaining funds to be released in March 2019.

Plea Agreement—Pursuant to 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, for which our subsidiary is no longer subject to probation.  We also agreed to make an aggregate cash payment of $400 million, including a criminal fine

and certain cash contributions payable in scheduled installments.  In the years ended December 31, 2017 and 2016, we made a cash payment of $60 million in each year, representing the final installments for our obligations under the Plea Agreement.

Global Marine litigation—On November 28, 2017, Wilmington Trust Company, in its capacity as trustee, filed a lawsuit in the Supreme Court of the State of New York County(the “Court”) related to such certain internal reorganization transactions and the Exchange Offers.  Additionally, in September and October 2020, Whitebox and funds managed by, or affiliated with, Pacific Investment Management Company LLC, as debtholders, together with certain other advisors and debtholders, provided purported notices of New York, against Global Marine Inc. (“Global Marine”), one of our wholly owned, indirect subsidiaries,alleged default with respect to the indentures governing, respectively, the 8.00% Guaranteed Notes and the 7.25% Guaranteed Notes.

On September 23, 2020, we filed an answer to the Claim with the Court and asserted counterclaims seeking a declaratory judgment that, Global Marine is inamong other matters, the Internal Reorganization did not cause a default under the indenture governing its $300 millionthe 8.00% Guaranteed Notes.  Concurrently, with our answer and counterclaims, we also submitted a motion for summary judgment seeking an expedited judgment on our request for declaratory judgment.  Whitebox subsequently submitted a cross-motion for summary judgment seeking dismissal of outstanding 7.00% Notes due June 2028.  We disagree withour counterclaims.  On November 30, 2020, while awaiting the assertionsCourt’s ruling on our motion for summary judgment, we amended certain of our financing documents and implemented certain internal reorganization transactions, which resolved the allegations contained in the lawsuitpurported notices of default.  On December 17, 2020, the Court issued its ruling granting our motion for summary judgment and believedenying the plaintiff’s cross-motion for summary judgment, holding, among other matters, that Global Marine is in compliance with the indenture and has meritorious defenses against these allegations although it can make no assurance regarding the outcome of the lawsuit, including the actual amount that would be duecontained in the event that the lawsuit is successful.  The notes are neither guaranteed by, nor recourse to, Transocean Ltd. or our other subsidiaries.  The claimants seek payment prior to the scheduled maturitypurported notice of the principal amount of notes outstanding and accrued but unpaid interest as well as make‑whole amounts under the indenture.  In addition, the acceleration of the amounts duedefault did not constitute a default under the indenture could, absent our payment ofgoverning the amounts due or otherwise staying any judgment therefrom, result8.00% Guaranteed Notes.  Whitebox has appealed the Court’s ruling.

The facts alleged in an eventthe purported notice of default under the 8.00% Guaranteed Notes were the same as the facts underlying the Claim and the purported notice of default under the 7.25% Guaranteed Notes.  Accordingly, following the amendment and internal reorganization transactions on November 30, 2020, and the subsequent ruling from the Court granting our currently undrawn Secured Credit Facility.  We intend to vigorously defend the lawsuit.  While we cannot predict or provide assurance as to the outcome of these proceedings,motion for summary judgment, we do not expect the proceedingsliability, if any, resulting from these matters to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

the Eastern District of Louisiana (the “MDL Court”), the court in which most claims against us were consolidated by the U.S. Judicial Panel on Multidistrict Litigation.  In Septemberthe years ended December 31, 2019 and 2018, we notified the customer ofMDL Court released $33 million and $58 million, respectively, from and escrow account established by the MDL Court to satisfy our intentions to enter into arbitration.  We intend to vigorously pursue full recovery of this receivable.  While we cannot predict or provide assurance as to its outcome, we do not expect it to have a material adverse effect on our consolidated statement of financial position, results of operations orobligations under the PSC Settlement Agreement.  At December 31, 2019, the remaining 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 summonsbalance in the Federal Highescrow account was $125 million, recorded in restricted cash accounts and investments.  In June 2020, the MDL Court released the remaining assets held in Lagos challenging the imposition of this surcharge onescrow account to satisfy our remaining obligations under 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.PSC Settlement Agreement.

Asbestos litigation—In 2004, several of our subsidiaries were named, along with numerous other unaffiliated defendants, in complaints filed in the Circuit Courts of the State of Mississippi, and in 2014, a group of similar complaints were filed in Louisiana.  The plaintiffs, former employees of some of the defendants, generally allege that the defendants used or manufactured asbestos containing drilling mud additives for use in connection with drilling operations, claiming negligence, products liability, strict liability and claims allowed under the Jones Act and general maritime law.  The plaintiffs generally seek awards of unspecified compensatory and punitive damages, but the court‑appointedcourt-appointed special master has ruled that a Jones Act employer defendant, such as us, cannot be sued for punitive damages.  At December 31, 2018, nine2020, 8 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.

OneNaN of our subsidiaries has been named as a defendant, along with numerous other companies, in lawsuits arising out of the subsidiary’s manufacture and sale of heat exchangers, and involvement in the construction and refurbishment of major industrial complexes alleging bodily injury or personal injury as a result of exposure to asbestos.  As of December 31, 2018,2020, the subsidiary was a defendant in approximately 156255 lawsuits with a corresponding number of plaintiffs.  For many of these lawsuits, we have not been provided sufficient information from the plaintiffs to determine whether all or some of the plaintiffs have claims against the subsidiary, the basis of any such claims, or the nature of their alleged injuries.  The operating assets of the subsidiary were sold in 1989.  In September 2018, the subsidiary and certain insurers agreed to a settlement of outstanding disputes that leavesprovided the subsidiary with funding, including cash annuities and an annuity.  Together with a coverage-in-place agreement with certain insurers and additional coverage in place settlement agreements withissued by other insurers, that we believe will bethe subsidiary has sufficient resources to respond to both the current lawsuits as well as future lawsuits of a similar nature.  While we cannot predict or provide assurance as to the outcome of these matters, we do not expect the ultimate liability, if any, resulting from these claims to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

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

or effect of any tax, regulatory, lawsuit or other litigation matter will prove correct and the eventual outcome of these matters could materially differ from management’s current estimates.

Environmental matters

We have certain potential liabilities under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and similar state acts regulating cleanup of hazardous substances at various 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.  It is difficult to quantify the potential cost of environmental matters and remediation obligations.  Liability is strict and can be joint and several.

One of our subsidiaries has beenwas named as a PRP in connection with a site located in Santa Fe Springs, California, known as the Waste Disposal, Inc. site.  We and other PRPs agreed, under a participation agreement with the U.S. Environmental Protection Agency (the “EPA”) and the U.S. Department of Justice, to settle our potential liabilities by remediating the site.  Under a participation agreement,The remedial action for the parties to the settlementsite was completed the required remediation, and we believe ourin 2006.  Our share approximately eight percent, of the ongoing future operationoperating and maintenance costs ishas been insignificant, and we do not material.  We have no reason to believe thatexpect any additional potential liabilities for the site willto be material.

One of our subsidiaries was ordered by the California Regional Water Quality Control Board (“CRWQCB”) to develop a testing plan for a site known as Campus 1000 Fremont in Alhambra, California, which is now a part of the San Gabriel Valley, Area 3, Superfund site.  We were also advised that one or more of our subsidiaries that formerly owned and operated the site would likely be named as a PRP or PRPs.  The current property owner, an unrelated party, performed the required testing and detected no contaminants, and based on such results, we would contest any potential liability.  In discussions with CRWQCB staff, we were advised of their intent to issue us a “no further action” letter, but it has not yet been received.  We have no knowledge of the potential cost of any remediation, who else will be named as PRPs, and whether in fact any of our subsidiaries is a responsible party.  The subsidiaries in question do not own any operating assets and have limited ability to respond to any liabilities.

Resolutions of other claims by the EPA, the involved state agency or PRPs are at various stages of investigation.  It is difficult to quantify the potential cost of environmental matters and remediation obligations.  Nevertheless, based on the available information, we do not expect the ultimate liability, if any, resulting from all environmental matters, including the liability for all related pending legal proceedings, asserted legal claims, the potential claims in Alhambra, California, for which tests detected no contaminants, and known potential legal claims that are likely to be asserted, to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

Redeemable noncontrolling interest—Until June 11, 2018, we owned a 65 percent interest in Angola Deepwater Drilling Company Ltd. (“ADDCL”), a Cayman Islands company and variable interest entity for which we concluded that we were the primary beneficiary.  Angco Cayman Limited (“Angco Cayman”) owned the remaining a 35 percent interest in ADDCL.  Under the terms of ADDCL’s governing documents, Angco Cayman had the right to require us to purchase its interest in ADDCL for cash, and accordingly, we presented the carrying amount of Angco Cayman’s ownership interest as redeemable noncontrolling interest on our consolidated balance sheets.  We also had the right under ADDCL’s governing documents to require Angco Cayman to sell us its interest, and we exercised that right.  On June 11, 2018, pursuant to a settlement requiring no0 cash payment, we acquired the interests in ADDCL not previously owned by us, and ADDCL became our wholly owned subsidiary.  In connection with the acquisition, we reclassifiedreallocated the $53 million aggregate carrying amount of the redeemable noncontrolling interest to additional paid‑inpaid-in capital.  At December 31, 2017, the carrying amount of the assets and liabilities of ADDCL, after eliminating the effect of intercompany transactions, was $716 million and $7 million, respectively.

Extraordinary general meetings—On November 29, 2018, in connection with the Ocean Rig acquisition, shareholders at our extraordinary general meeting approved: (1) an amendment of our articles of association to create additional authorized share capital, (2) the issuance of up to 147.7 million Transocean Ltd. shares and (3) the deletion of the previously approved special purpose authorized share capital.  On January 16, 2018, in connection with the Songa acquisition, shareholders at our extraordinary general meeting approved: (1) the issuance of up to 68.6 million Transocean Ltd. shares, (2) an amendment of our articles of association to create additional authorized share capital, (3) the election of a new director to our board of directors and (4) the issuance of consideration shares from our authorized share capital and shares issuable upon exchange of the Exchangeable Bonds.

Note 15—Share‑BasedShare-Based Compensation

Overview

We have a long‑termlong-term incentive plan (the “Long‑Term“Long-Term Incentive Plan”) for executives, key employees and non‑employeenon-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‑TermLong-Term Incentive Plan.  At December 31, 2018,2020, we had 32.762.9 million shares authorized and 15.022.0 million shares available to be granted under the Long‑TermLong-Term Incentive Plan.  At December 31, 2018,2020, the total unrecognized compensation cost related to our unvested share‑basedshare-based awards was $37$24 million, which is expected to be recognized over a weighted‑averageweighted-average period of 1.71.4 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 or shares to be issued remains uncertain until the end of the measurement period, at which time the awarded number of options or shares to be issued is determined.  The performance awards typically vest in one aggregate installment following the determination date.  Stock options are subject to a stated vesting period and, once vested, typically have a seven‑yearseven-year term during which they are exercisable.

We estimated the fair value of each class of financial instruments, for which estimating fair value is practicable, by applying the following methods and assumptions:

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

Short‑term investments—The carrying amount of our unrestricted short‑term investments represents the historical cost of the time deposits in which they are invested.  The carrying amount of such short‑term investments approximates fair value because of the near‑term maturities of the instruments.

Restricted cash and cash equivalentsThe carrying amount of ourOur restricted cash and cash equivalents, which are subject to restrictions due to collateral requirements, legislation, regulation or court order, approximates fair value due to the near‑term maturities of the instrumentsare primarily invested in which the restricted balances are held.  At December 31, 2018, the aggregate carrying amount of such restricted cashdemand deposits, short-term time deposits and cash equivalents was $429 million, including $428 million and $1 million, recorded in current assets and other assets, respectively.  At December 31, 2017, the aggregate carrying amount of such restricted cash and cash equivalents was $456 million, including $440 million and $16 million, recorded in current assets and other assets, respectively.

Restricted investmentsmoney market funds.  The carrying amount of our restricted investments,cash and cash equivalents represents the historical cost, plus accrued interest, which are subject to restrictions due to court order or pledged for security of certain credit arrangements, approximates fair value because of the near‑termshort maturities of the instruments.  At December 31, 2018, the aggregate carrying amount of the restricted investments was $123 million, recorded in other current assets.  At December 31, 2017, the aggregate carrying amount of the restricted investments was $26 million and $7 million, recorded in current assets and other assets, respectively.

Debt—The carrying amount of our debt represents the principal amount, net of unamortized discounts, premiums, debt issue costs and fair value adjustments.  We measured the estimated fair value of our debt using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments.

Derivative instruments—The carrying amount of our derivative instruments represents the estimated fair value of such instruments.  We measured the estimated fair value of our derivative instruments using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments.

Note 19—Risk Concentration

Interest rate risk—Financial instruments that potentially subject us to concentrations of interest rate risk include our restricted and unrestricted cash equivalents short‑term investments, restricted cash investments, debt and capital lease obligations.debt.  We are exposed to interest rate risk related to our restricted and unrestricted cash equivalents, and short‑term investments, as the interest income earned on these investments is based on variable or short‑termshort-term interest rates, which change with market interest rates.  We are also exposed to the interest rate risk related to our fixed‑ratefixed-rate debt when we refinance maturing debt with new debt or when we repurchase or retire debt in open market repurchases.repurchases or other market transactions.

Currency exchange rate riskOur international operations expose usWe are exposed to currency exchange rate risk.risk related to our international operations.  This risk is primarily associated with compensation costs of our employees and purchasing costs from non‑U.S.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.

terms and occasional use of forward exchange contracts.  Our primary strategy for 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.

We earn our revenues by providing our drilling services to internationalintegrated oil companies, government‑ownedgovernment-owned or government-controlled oil companies and government‑controlledother independent oil companies.  ReceivablesOur receivables are dispersed in various countries (see Note 20—Operating Segments, Geographic Analysis and Major Customers).countries.  We establish an allowance for doubtful accountscredit losses by applying an expected loss rate based 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.current and forecasted future and historical experience.  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 agreementsWe require highly skilled personnel to operate our drilling units.  We conduct extensive personnel recruiting, training and safety programs.  At December 31, 2018,2020, we had a global workforce of approximately 6,700 employees,5,350 individuals, including approximately 800 persons engaged through contract labor providers.530 contractors.  Approximately 3443 percent of our total workforce, working primarily in Norway, Brazil U.K. and Australiathe U.K., are represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially all of which are subject to annual salary negotiation.  These negotiationsNegotiations over annual salary or other labor matters could result in higher personnel expenses,or other increased costs or increased operational restrictions as theor disruptions.  The outcome of any such negotiations affectnegotiation generally affects the market for all offshore employees,

Note 20—Operating Segments, Geographic Analysis and Major Customers

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