Item 1. Business,” “Part I. Item 1A. Risk Factors” and the audited consolidated financial statements and the notes thereto included under “Item 8. Financial Statements and Supplementary Data” elsewhere in this annual report 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, 2022 and 2021.  For a discussion, including comparisons, of our results of operations and liquidity and capital resources for the years ended December 31, 2021 and 2020, 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, 2021, filed with the United States (“U.S.”) Securities and Exchange Commission on February 23, 2022. Business Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells.  As of February 14, 2023, we owned or had partial ownership interests in and operated 37 mobile offshore drilling units, consisting of 27 ultra-deepwater floaters and 10 harsh environment floaters.  Additionally, as of February 14, 2023, we were constructing one ultra-deepwater drillship and held a noncontrolling ownership interest in a company that is constructing one ultra-deepwater drillship. We provide, as our primary business, contract drilling services in a single operating segment, which involves contracting our mobile offshore drilling rigs, related equipment and work crews to drill oil and gas wells.  We specialize in technically demanding regions of the global offshore drilling business with a particular focus on ultra-deepwater and harsh environment drilling services.  Our 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. We perform contract drilling services by deploying our high-specification fleet in a single, global market that is geographically dispersed in oil and gas exploration and development areas throughout the world.  Although rigs can be moved from one region to another, the cost of moving rigs and the availability of rig-moving vessels may cause the supply and demand balance to fluctuate somewhat between regions.  Still, significant variations between regions do not tend to persist long term because of rig mobility.  The location of our rigs and the allocation of resources to operate, build or upgrade our rigs are determined by the activities and needs of our customers. Significant Events Fleet expansion—In October 2022, we completed the construction of and placed into service the ultra-deepwater floater Deepwater Atlas.  In November 2022, we made a cash contribution of $15 million associated with our noncontrolling ownership interest in Liquila Ventures Ltd. (together with its subsidiaries, “Liquila”), a Bermuda company formed to construct, own and operate the newbuild ultra-deepwater drillship Deepwater Aquila.  See “—Liquidity and Capital Resources—Sources and uses of liquidity” and “—Liquidity and Capital Resources—Drilling fleet.” Secured debt issuance—In January 2023, we issued $525 million aggregate principal amount of 8.375% senior secured notes due February 2028 (the “8.375% Senior Secured Notes”), and we received $515 million aggregate cash proceeds, net of issue costs.  In January 2023, we issued $1.175 billion aggregate principal amount of 8.75% senior secured notes due February 2030 (the “8.75% Senior Secured Notes”), and we received $1.157 billion aggregate cash proceeds, net of issue costs.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.” Debt and warrant issuance—In September 2022, we issued $300 million aggregate principal amount of 4.625% senior guaranteed exchangeable bonds due September 2029 (the “4.625% Senior Guaranteed Exchangeable Bonds”) in connection with (a) the issuance for aggregate cash proceeds of $188 million and (b) the exchanges (the “2022 Private Exchange”) of certain of the 0.50% exchangeable senior bonds due January 2023 (the “0.50% Exchangeable Senior Bonds”) and the 7.25% senior notes due November 2025 (the “7.25% Senior Notes”).  In connection with the 2022 Private Exchange, we also issued 22.2 million warrants to purchase Transocean Ltd. shares.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.” Shipyard Loans—In June 2022, we borrowed $349 million under one of two credit agreements (each, a “Shipyard Loan,” and together, the “Shipyard Loans”) and made a cash payment of $46 million to satisfy the final milestone payment due upon delivery of Deepwater Atlas.  In December 2022, we borrowed $90 million under the second Shipyard Loan and made a cash payment of $325 million to satisfy the final milestone payment due upon delivery of Deepwater Titan.  We recorded the Shipyard Loan for Deepwater Atlas and Deepwater Titan, net of imputed interest, and the corresponding non-cash capital additions of $300 million and $82 million, respectively.  See “—Liquidity and Capital Resources—Sources and uses of liquidity” and “—Liquidity and Capital Resources—Drilling fleet.” Early debt retirement—In January 2023, in connection with the issuance of the 8.75% Senior Secured Notes, we made an aggregate payment of $1.156 billion, including a make-whole premium, to redeem the remaining outstanding $311 million, $240 million, $250 million, and $336 million aggregate principal amount of the 5.875% senior secured notes due January 2024 (the “5.875% Senior Secured Notes”), the 7.75% senior secured notes due October 2024 (the “7.75% Senior Secured Notes”), the 6.25% senior secured notes - 26 - Table of Contents due December 2024 (the “6.25% Senior Secured Notes”) and the 6.125% senior secured notes due August 2025 (the “6.125% Senior Secured Notes”), respectively. In January 2023, we made a cash payment of $121 million to redeem an equivalent aggregate principal amount of the outstanding 5.375% senior secured notes due May 2023 (the “5.375% Senior Secured Notes”), and the trustee notified holders of our intent to redeem the remaining outstanding $122 million aggregate principal amount of notes for an equivalent aggregate cash payment, expected to be made on February 24, 2023. In July 2022, we made an aggregate cash payment of $27 million to redeem an equivalent aggregate principal amount of the then outstanding 3.80% senior notes due October 2022 (the “3.80% Senior Notes”).  In January 2022, we made an aggregate cash payment of $18 million to redeem an equivalent aggregate principal amount of the 5.52% senior secured notes due May 2022 (the “5.52% Senior Secured Notes”).  See “—Operating Results” and “—Liquidity and Capital Resources—Sources and uses of liquidity.” Share issuance—In June 2021, we commenced an at-the-market equity offering program (the “ATM Program”).  In the year ended December 31, 2022, we received aggregate cash proceeds of $263 million, net of issue costs, for the aggregate sale of 61.0 million shares under the ATM Program.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.” Secured credit facility amendment—In July 2022, we amended the bank credit agreement for our Secured Credit Facility (as amended from time to time, the “Secured Credit Facility”) to, among other things, extend the maturity date from June 22, 2023 to June 22, 2025 and reduce the borrowing capacity from $1.33 billion to $774 million through June 22, 2023, and thereafter, reduce the borrowing capacity to $600 million through June 22, 2025.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.” Outlook Drilling market—Our industry outlook is positive based upon several fundamental factors, including the increased global demand for hydrocarbons combined with a diminishing global supply, the latter being the result of the natural decline in production of existing oil and gas fields compounded by the significant underinvestment in reserve replacement by oil and gas producers, and additional constraints imposed on industry participants by the governments of oil and gas producing nations as well as investors.  Additionally, the Russian invasion of Ukraine and the related economic sanctions have highlighted the criticality of energy reliability and security across Europe, the U.S. and elsewhere.  Due to these and other factors, oil prices have increased materially over the past two years and even reached 10-year highs. Although the price for both prompt and longer-dated barrels continues to exhibit volatility that reflects market concerns about inflationary trends, economic recession and the potential for demand destruction, these commodity prices are currently, and are expected to remain, at levels that are robustly supportive of investment in deepwater and harsh environment exploration and development projects.  Additionally, rig attrition resulting from significantly reduced offshore contracting activity over the last several years has resulted in a much smaller global fleet of floating rigs that is available to meet customer demands, specifically with respect to the highest specification drilling units required by many of our customers for their projects.  Consequently, our outlook for the offshore drilling industry overall remains positive, particularly for high-specification drilling assets, such as those we own and operate. Our customers continue to show interest in deepwater and harsh environment offshore projects as evidenced by the restarting of delayed projects and commencement of new drilling campaigns.  Licensing activity has also increased as energy companies look to explore and develop new prospects.  This has resulted in more tendering activity during the last half of 2022 and into 2023.  Several multi-year tenders for work in Brazil, West Africa, Asia and Australia are expected to be awarded in the first nine months of 2023.  We have recently observed that the commencement of certain projects or parts of a project is, in some cases, being delayed due to global supply chain constraints adversely impacting the timely availability of necessary equipment and supplies.  We currently believe that these temporary circumstances will gradually diminish over the short to medium term. Offshore drilling activity is increasing in every ultra-deepwater geographic sector.  South America, the U.S. Gulf of Mexico and, increasingly, West Africa remain key ultra-deepwater market sectors.  We have seen significant increases in dayrates for projects in the U.S. Gulf of Mexico and, particularly, in Brazil, trends that we expect will continue.  In Norway, the largest market for harsh environment rigs, we do not expect many new projects to commence before late 2023, but we expect demand for rigs in this market will accelerate thereafter through 2026 due to previously enacted Norwegian tax incentive programs.  Given the highly regulated nature of the Norwegian market and the limited number of rigs qualified to operate in it, we anticipate an increase in dayrates commensurate with the increased demand.  We are also encouraged by projects being announced in the United Kingdom, Namibia, South Africa and Australia that require high-specification, harsh environment semisubmersibles.  As expected, these opportunities are attracting rigs currently working in Norway, thereby further reducing rig supply and potentially accelerating dayrate increases for the remaining assets in the region. We expect global energy demand to continue to increase in both member and non-member countries of the Organization for Economic Co-operation and Development.  Forecasts indicate that non-member countries will experience the largest population growth and require the most significant improvement in living standards, compounding the effect on energy demand for the foreseeable future.  We believe that this increase in global energy demand will result in meaningful incremental demand for oil and gas.  In the context of the pronounced decline in investment in exploration and production activities over the last decade, we anticipate that a prolonged period of elevated hydrocarbon prices and investment in drilling activity will be necessary to meet this demand. - 27 - Table of Contents With deepwater and harsh environment fields generating robust economic returns versus other hydrocarbon sources, combined with their comparably low carbon intensity of production, we expect a significant portion of the required spending in fossil fuel development will be allocated to deepwater and harsh environment projects.  As there are now fewer high-specification offshore drilling rigs capable of operating in these markets, we believe that this increase in demand will support further improvement of dayrates. As of February 9, 2023, our contract backlog was $8.54 billion compared to $7.27 billion as of October 13, 2022.  The risks of drilling project delays, contract renegotiations and contract terminations and cancellations have diminished as oil prices have improved and stabilized. Fleet status—We refer to the availability of our rigs in terms of the uncommitted fleet rate.  The uncommitted fleet rate is defined as the number of uncommitted days divided by the total number of rig calendar days in the measurement period, expressed as a percentage.  An uncommitted day is defined as a calendar day during which a rig is idle or stacked, is not contracted to a customer and is not committed to a shipyard.  The uncommitted fleet rates exclude the effect of priced options.  As of February 9, 2023, our uncommitted fleet rates for each of the five years in the period ending December 31, 2027 were as follows: [[GREPCENT_TABLE]] [["\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["\u200b","","2023","","2024","","2025","","2026","","2027"],["Uncommitted fleet rate","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["Ultra-deepwater floaters","\u200b","39","%","\u200b","56","%","\u200b","67","%","\u200b","76","%","\u200b","84","%","\u200b"],["Harsh environment floaters","\u200b","42","%","\u200b","71","%","\u200b","89","%","\u200b","90","%","\u200b","96","%","\u200b"]] [[/GREPCENT_TABLE]] Performance and Other Key Indicators Contract backlog—We believe our industry leading contract backlog sets us apart from the competition and provides indicators of our future revenue-earning opportunities.  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.  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.  The contract backlog for our fleet was as follows: [[GREPCENT_TABLE]] [["\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["\u200b","\u200b","February 9,","\u200b","October 13,","\u200b","February 14,"],["\u200b","","2023","","2022","","2022"],["\u200b","\u200b","(in millions)"],["Contract backlog","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["Ultra-deepwater floaters","\u200b","$","7,378","","$","6,327","","$","5,301","\u200b"],["Harsh environment floaters","\u200b","\u200b","1,159","\u200b","\u200b","943","\u200b","\u200b","1,165","\u200b"],["Total contract backlog","","$","8,537","","$","7,270","","$","6,466","\u200b"]] [[/GREPCENT_TABLE]] Our contract backlog includes only firm commitments, including amounts associated with our contracted newbuild units under construction, 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.

The contractual operating dayrate may be higher than the actual dayrate we ultimately receive because an alternative contractual dayrate, such as a waiting-on-weather rate, repair rate, standby rate or force majeure rate, may apply under certain circumstances.  The - 28 - Table of Contents 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 actual dayrate may be reduced to zero if, for example, repairs extend beyond a stated period of time.  See “Part I. Item 1A. Risk Factors—Risks related to our business—Our current backlog of contract drilling revenues may not be fully realized.” Average daily revenue—We believe average daily revenue provides a comparative measurement unit for our revenue-earning performance.  Average daily revenue is defined as operating revenues, excluding revenues for contract terminations, reimbursements and contract intangible amortization, earned per operating day.  The average daily revenue for our fleet was as follows: [[GREPCENT_TABLE]] [["\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["\u200b","\u200b","Years ended December 31,","\u200b"],["\u200b","","2022","","2021","","2020"],["Average daily revenue","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["Ultra-deepwater floaters","\u200b","$","329,100","","$","355,500","\u200b","$","324,500","\u200b"],["Harsh environment floaters","\u200b","$","380,000","\u200b","$","386,200","\u200b","$","339,600","\u200b"],["Midwater floaters","\u200b","$","\u2014","","$","\u2014","\u200b","$","111,400","\u200b"],["Total fleet average daily revenue","\u200b","$","345,500","","$","365,600","\u200b","$","327,500","\u200b"]] [[/GREPCENT_TABLE]] Our average daily revenue fluctuates relative to market conditions and our revenue efficiency.  The average daily revenue may be affected by incentive performance bonuses or penalties or demobilization fee revenues.  Our total fleet average daily revenue is affected by the mix of rig classes being operated.  Midwater floaters, for example, which we no longer operate, are typically contracted at lower dayrates compared to ultra-deepwater floaters and harsh environment floaters.  Revenues for a contracted newbuild unit are included in the calculation when the rig commences 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, in which case we remove the rigs at the time of completion or novation of the contract. Revenue efficiency—We believe revenue efficiency measures our ability to ultimately convert our contract backlog into revenues.  Revenue efficiency is defined as actual operating 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 the drilling unit could earn for the measurement period, excluding revenues for incentive provisions, reimbursements and contract terminations.  The revenue efficiency rates for our fleet were as follows: [[GREPCENT_TABLE]] [["\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["\u200b","\u200b","Years ended December 31,","\u200b"],["\u200b","\u200b","2022","","2021","","2020"],["Revenue efficiency","\u200b","\u200b","\u200b","\u200b","\u200b","\u200b"],["Ultra-deepwater floaters","\u200b","95.7","%","96.1","%","97.2","%"],["Harsh environment floaters","\u200b","97.6","%","98.8","%","95.0","%"],["Midwater floaters","\u200b","\u2014","%","\u2014","%","86.2","%"],["Total fleet average revenue efficiency","\u200b","96.4","%","97.0","%","96.3","%"]] [[/GREPCENT_TABLE]] Our revenue efficiency rate varies due to revenues earned under alternative contractual dayrates, such as a waiting-on-weather rate, repair rate, standby rate, force majeure rate or zero rate, that may apply under certain circumstances.  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.

Contract drilling revenues—Contract drilling revenues increased for the year ended December 31, 2022, compared to the year ended December 31, 2021, primarily due to the following: (a) approximately $25 million resulting from Deepwater Atlas, which was placed into service in October 2022, (b) approximately $20 million resulting from increased rig utilization, (c) approximately $10 million resulting from higher early termination revenues and (d) approximately $10 million resulting from higher reimbursable revenues.  These increases were partially offset by (a) approximately $40 million resulting from lower dayrates and (b) approximately $5 million resulting from lower fleet revenue efficiency. Costs and expenses—Operating and maintenance costs and expenses decreased for the year ended December 31, 2022, compared to the year ended December 31, 2021, primarily due to the following: (a) approximately $35 million resulting from the effect of favorable exchange rates, (b) approximately $28 million resulting from the allowance for excess materials and supplies due to the identification, in the year ended December 31, 2021, of parts that were in excess of our expected future usage, (c) approximately $15 million resulting from reduced rig out-of-service maintenance costs and (d) approximately $5 million incurred on rigs sold in the year ended December 31, 2021.  These decreases were partially offset by the following increases: (a) approximately $25 million resulting from personnel compensation increases, (b) approximately $20 million resulting from increased rig operating activities, (c) approximately $15 million resulting from Deepwater Atlas and (d) approximately $10 million resulting from higher customer reimbursable costs. Depreciation and amortization expense decreased for the year ended December 31, 2022, compared to the year ended December 31, 2021, primarily due to (a) approximately $17 million resulting from assets that had reached the end of their useful lives or had been retired, partially offset by (b) approximately $10 million of increased depreciation associated with our newbuild ultra-deepwater drillship and other property and equipment placed into service in the year ended December 31, 2022. General and administrative expense increased for the year ended December 31, 2022, compared to the year ended December 31, 2021, primarily due to the following: (a) approximately $8 million of increased costs for information systems and technology and (b) approximately $3 million of increased costs for strategy and innovation. Disposal of assets—In the year ended December 31, 2021, we recognized an aggregate net loss of $57 million, primarily associated with the sale of a harsh environment floater and related assets.  In the years ended December 31, 2022 and 2021, we recognized an aggregate net loss of $10 million and $5 million, respectively, associated with the disposal of assets unrelated to rig sales. Other income and expense—Interest expense, net of amounts capitalized, increased in the year ended December 31, 2022, compared to the year ended December 31, 2021, primarily due to the following: (a) an increase of $157 million resulting from the fair value adjustment of the bifurcated compound exchange feature embedded in the 4.625% Senior Guaranteed Exchangeable Bonds and (b) an increase of $15 million resulting from borrowings under the Shipyard Loans, partially offset by (c) a decrease of $41 million resulting from - 30 - Table of Contents debt repaid as scheduled or early retired and (d) a decrease of $23 million resulting from increased interest capitalized for our newbuild construction projects. In the year ended December 31, 2022, we recognized an aggregate net gain on the retirement of debt, primarily associated with the retirement of $116 million aggregate principal amount of debt as a result of the 2022 Private Exchange.  In the year ended December 31, 2021, we recognized an aggregate net gain on the retirement of debt, primarily associated with the retirement of $323 million aggregate principal amount of debt as a result of the private exchanges completed in February 2021 (the “2021 Private Exchange”). Other expense, net, increased in the year ended December 31, 2022, compared to the year ended December 31, 2021, primarily due to the following: (a) income of $32 million resulting from settlement of litigation recognized in the year ended December 31, 2021, (b) increased loss of $11 million related to our investment in Nauticus Robotics, Inc. (“Nauticus”), (c) reduced income of $7 million related to our dual-activity patent, (d) increased losses of $7 million resulting from net changes to currency exchange rates, and (e) reduced income of $5 million related to the non-service components of net periodic benefit income, partially offset by (f) reduced losses of $33 million related to our investment in Orion Holdings (Cayman) Limited (“Orion”). Income tax expense—In the years ended December 31, 2022 and 2021, our effective tax rate was (10.4) percent and (25.7) percent, respectively, based on loss before income tax expense.  In the years ended December 31, 2022 and 2021, the aggregate effect of discrete period tax items was a net tax benefit of $19 million and net tax expense of $47 million, respectively.  In the year ended December 31, 2022, such discrete items included settlement and expiration of various uncertain tax positions, changes to valuation allowances, operational restructuring and gains due to exchange rate changes.  In the year ended December 31, 2021, such discrete items included the effect of tax law changes in Switzerland and jurisdictional ownership changes of certain assets, loss on disposal of assets, expiration and settlements of various uncertain tax positions, gain on retirement of debt, changes to our allowance for excess materials and loss on impairment of an equity investment.  In the years ended December 31, 2022 and 2021, our effective tax rate, excluding discrete items, was (13.6) percent and (18.5) percent, respectively, based on loss before income tax expense.  In the year ended December 31, 2022 compared to the year ended December 31, 2021, our effective tax rate increased primarily due to changes in the relative blend of income from operations in certain jurisdictions. Due 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, 2022, a significant portion of our income tax expense was generated in countries in which income taxes are imposed or treated to be imposed on gross revenues, with the most significant of these countries being Angola and India.  Conversely, during this period, the most significant countries in which we incurred income taxes that were based on income before income tax included the U.S., Hungary and Switzerland.  Our rig operating structures further complicate our tax calculations, especially in instances where we have more than one operating structure for the taxing jurisdiction and, thus, more than one method of calculating taxes depending on the operating structure utilized by the rig under the contract. Liquidity and Capital Resources Sources and uses of cash At December 31, 2022, we had $683 million in unrestricted cash and cash equivalents and $308 million in restricted cash and cash equivalents.  In the year ended December 31, 2022, our primary sources of cash were net cash provided by our operating activities, net cash proceeds from the issuance of shares under the ATM Program and net cash proceeds from the issuance of debt.  Our primary uses of cash were debt repayments and capital expenditures.

Sources and uses of liquidity Overview—We expect to use existing unrestricted cash balances, internally generated cash flows, borrowings under our Secured Credit Facility or proceeds from the disposal of assets or the issuance of debt or shares to fulfill anticipated near-term obligations, which may include capital expenditures, working capital and other operational requirements, scheduled debt maturities or other payments.  We may consider establishing additional financing arrangements with banks or other capital providers, and subject to market conditions and other factors, we may be required to provide collateral for any such future financing arrangements. 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.  Among other factors, if general economic, financial, industry or business conditions deteriorate, if we experience poor operating results, or if we incur costs to, for example, reactivate, stack or otherwise assure the marketability of our fleet, our cash flows from operations may be reduced or negative. 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 our expected liquidity needs, among other factors, we may continue to use existing unrestricted cash balances, internally generated cash flows and proceeds from asset sales to pursue liability management transactions, including among others, purchasing or exchanging one or more existing series of our debt securities in the open market, in privately negotiated transactions, through tender offers or through exchange offers.  Any future purchases, exchanges or 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 our previous exchange transactions.  We can provide 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. Our ability and willingness to access the debt and equity markets is a function of a variety of factors, including, among others, general economic, industry or market conditions, market perceptions of us and our industry and credit rating agencies’ views of our debt.  General economic or market conditions could have an adverse effect on our business and financial position and on the business and financial position of our customers suppliers and lenders and could affect our ability to access the capital markets on acceptable terms or at all and 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 could impact our liquidity or need to alter our allocation or sources of capital, implement further cost reduction measures and change our financial strategy.  Additionally, the rating of the majority of our long-term debt, which is below investment grade, is causing us to experience increased fees and interest rates under our Secured Credit Facility and agreements governing certain of our senior notes.  Future downgrades may further restrict our ability to access the debt market for sources of capital and may negatively impact the cost of such capital 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. Debt issuances—In January 2023, we issued $525 million aggregate principal amount of 8.375% Senior Secured Notes, and we received $515 million aggregate cash proceeds, net of issue costs.  The 8.375% Senior Secured Notes are secured by the assets and earnings associated with the ultra-deepwater floater Deepwater Titan and the equity of the wholly owned subsidiary that owns or operates - 32 - Table of Contents the collateral rig.  Additionally, we are required to maintain certain balances in a restricted cash account to satisfy debt service requirements.  We may redeem all or a portion of the 8.375% Senior Secured Notes on or prior to February 1, 2025 at a price equal to 100 percent of the aggregate principal amount plus a make-whole premium, and subsequently, at specified redemption prices. In January 2023, we issued $1.175 billion aggregate principal amount of 8.75% Senior Secured Notes, and we received $1.157 billion aggregate cash proceeds, net of issue costs.  The 8.75% Senior Secured Notes are fully and unconditionally guaranteed on an unsecured basis by Transocean Ltd. and on a limited senior secured basis by certain of our wholly owned subsidiaries.  The 8.75% Senior Secured Notes are secured by a lien on the ultra-deepwater floaters Deepwater Pontus, Deepwater Proteus and Deepwater Thalassa and the harsh environment floaters Transocean Enabler and Transocean Encourage, together with certain related assets.  Additionally, we are required to maintain certain balances in a restricted cash account to satisfy debt service requirements. Early debt retirement—In January 2023, in connection with the issuance of the 8.75% Senior Secured Notes, we made an aggregate payment of $1.156 billion, including a make-whole premium, to redeem the remaining outstanding $311 million, $240 million, $250 million, and $336 million aggregate principal amount of the 5.875% Senior Secured Notes, the 7.75% Senior Secured Notes, the 6.25% Senior Secured Notes and the 6.125% Senior Secured Notes, respectively. In January 2022, we made an aggregate cash payment of $18 million to repay the then outstanding equivalent aggregate principal amount of the 5.52% Senior Secured Notes, and as a result, the noteholders subsequently released all liens, the mortgage on the secured rig and $106 million from restricted cash accounts.  In July 2022, we made an aggregate cash payment of $27 million to redeem the then outstanding equivalent aggregate principal amount of the 3.80% Senior Notes. In October 2022, the harsh environment floater Transocean Equinox, which is held as collateral for the 5.375% Senior Secured Notes, concluded its drilling contract following a notice received from the customer in September 2022.  As required under the indenture governing such notes, in January 2023, we made a cash payment of $121 million to redeem an equivalent aggregate principal amount of the outstanding securities.  Additionally, in January 2023, the trustee notified holders of our intent to redeem the remaining outstanding $122 million aggregate principal amount of notes for an equivalent aggregate cash payment, expected to be made on February 24, 2023. In the year ended December 31, 2021, we made an aggregate cash payment of $79 million to repurchase in the open market an equivalent aggregate principal amount of our debt securities. Shipyard financing arrangement—We established the Shipyard Loans to finance all or a portion of the final payments expected to be owed to the shipyard upon delivery of the ultra-deepwater floaters Deepwater Atlas and Deepwater Titan.  In June 2022, we borrowed $349 million under one of the Shipyard Loans and made a cash payment of $46 million to satisfy the final milestone payment due upon delivery of Deepwater Atlas.  In December 2022, we borrowed $90 million under the other Shipyard Loan and made a cash payment of $325 million to satisfy the final milestone payment due upon delivery of Deepwater Titan.  The Shipyard Loans are guaranteed by Transocean Inc.  Borrowings under the Shipyard Loan for Deepwater Atlas are secured by, among other security, a lien on the rig.  Borrowings under the Shipyard Loan for Deepwater Titan are unsecured.  We have the right to prepay the outstanding borrowings, in full or in part, without penalty.  The Shipyard Loans contain covenants that, among other things, limits the ability of the subsidiary owners of the drilling rigs to incur certain types of additional indebtedness or make certain additional commitments or investments. Debt exchanges—In September 2022, we issued $300 million aggregate principal amount of 4.625% Senior Guaranteed Exchangeable Bonds in connection with exchange and purchase agreements.  Pursuant to the exchange and purchase agreements, we exchanged (a) $73 million aggregate principal amount of the 0.50% Exchangeable Senior Bonds for (i) $73 million aggregate principal amount of the 4.625% Senior Guaranteed Exchangeable Bonds and (ii) 6.7 million warrants to purchase Transocean Ltd. shares, and (b) $43 million aggregate principal amount of the 7.25% Senior Notes for $39 million aggregate principal amount of the 4.625% Senior Guaranteed Exchangeable Bonds.  Additionally, we sold $188 million aggregate principal amount of the 4.625% Senior Guaranteed Exchangeable Bonds and issued 15.5 million warrants to purchase Transocean Ltd. shares for aggregate net cash proceeds of $188 million.  On or after March 30, 2026, we may redeem for cash all or a portion of the 4.625% Senior Guaranteed Exchangeable Bonds at a price equivalent to the aggregate principal amount to be redeemed if the closing price of our shares has been greater than 115 percent of the exchange price for a period of at least 20 trading days. In February 2021, we issued $294 million aggregate principal amount of the 4.00% senior guaranteed exchangeable bonds due December 2025 (the “4.00% Senior Guaranteed Exchangeable Bonds”) and made an aggregate cash payment of $11 million in the 2021 Private Exchange for $323 million aggregate principal amount of the 0.50% Exchangeable Senior Bonds.  The 4.00% Senior Guaranteed Exchangeable Bonds are guaranteed by Transocean Ltd. and the same subsidiaries of Transocean Inc. that guarantee the 2.50% senior guaranteed exchangeable bonds due January 2027 (the “2.50% Senior Guaranteed Exchangeable Bonds”) and the 11.50% senior guaranteed notes due January 2027.  The indenture that governs the 4.00% Senior Guaranteed Exchangeable Bonds also requires such bonds to be repurchased upon the occurrence of certain fundamental changes and events, at specified prices depending on the particular fundamental change or event, which include changes and events related to certain (i) change of control events applicable to Transocean Ltd. or Transocean Inc., (ii) the failure of our shares to be listed or quoted on a national securities exchange and (iii) specified tax matters.  The 4.00% Senior Guaranteed Exchangeable Bonds may be exchanged at any time prior to the close of business on the second business day immediately preceding the maturity date at a current exchange rate of 190.4762 Transocean Ltd. shares per $1,000 note, which implies an exchange price of $5.25 per share, subject to adjustment upon the occurrence of certain events, and any such exchange may be settled in cash, Transocean Ltd. shares or a combination of cash and Transocean Ltd. shares, at our election. - 33 - Table of Contents Share issuance—We intend to use the net proceeds from the sale of our shares under the ATM Program for general corporate purposes, which may include, among other things the repayment or refinancing of indebtedness and the funding of working capital, capital expenditures, investments and additional balance sheet liquidity.  In the years ended December 31, 2022 and 2021, we received aggregate cash proceeds of $263 million and $158 million, respectively, net of issue costs, for the aggregate sale of 61.0 million shares and 36.1 million shares, respectively, under the ATM Program. Secured Credit Facility—In July 2022, we amended the bank credit agreement for our Secured Credit Facility to, among other things, (i) extend the maturity date from June 22, 2023 to June 22, 2025, (ii) reduce the borrowing capacity from $1.33 billion to $774 million through June 22, 2023, and thereafter reduce the borrowing capacity to $600 million through June 22, 2025 and (iii) replace our ability to borrow under the Secured Credit Facility at the reserve adjusted London Interbank Offered Rate plus a margin (the “Secured Credit Facility Margin”) with the ability to borrow under the Secured Credit Facility at a forward looking term rate based on the secured overnight financing rate (“Term SOFR”) plus the Secured Credit Facility Margin and a Term SOFR spread adjustment of 0.10 percent.  The Secured Credit Facility is subject to permitted extensions and certain early maturity triggers, including if on any date the aggregate amount of scheduled principal repayments of indebtedness, with certain exceptions, due within 91 days thereof is equal to or in excess of $200 million and available cash is less than $250 million.  The amended secured credit facility also permits us to increase the aggregate amount of commitments by up to $250 million.  The Secured Credit Facility is guaranteed by Transocean Ltd. and certain wholly owned subsidiaries.  The Secured Credit Facility is secured by, among other things, a lien on nine of our ultra-deepwater floaters and two of our harsh environment floaters. The Secured Credit Facility contains covenants that, among other things, include maintenance of a minimum guarantee coverage ratio of 3.0 to 1.0, a minimum collateral coverage ratio of 2.1 to 1.0, 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 utilize the Secured Credit Facility, we must, at the time of the borrowing request, be in full compliance with the terms and conditions of the Secured Credit Facility and make certain representations and warranties, including with respect to compliance with laws and solvency, to the lenders.  Repayment of borrowings under the Secured Credit Facility are subject to acceleration upon the occurrence of an event of default.  Under the agreements governing certain of our debt and finance lease, we are also subject to various covenants, including restrictions on creating liens, engaging in sale/leaseback transactions and engaging in certain merger, consolidation or reorganization transactions.  A default under our public debt indentures, the agreements governing our senior secured notes, our finance lease contract or any other debt owed to unaffiliated entities that exceeds $125 million could trigger a default under the Secured Credit Facility and, if not waived by the lenders, could cause us to lose access to the Secured Credit Facility.  At February 14, 2023, we had no borrowings outstanding, $6 million of letters of credit issued, and we had $767 million of available borrowing capacity under the Secured Credit Facility. Equity and debt investments—In the years ended December 31, 2022 and 2021, we made cash investments of $25 million and $34 million, respectively, in the equity and debt of certain unconsolidated affiliates, such as Orion and Liquila, that own drilling units.  In the year ended December 31, 2022, we made a cash contribution of $15 million to Liquila, which was used by Liquila to make the initial payment to the shipyard to acquire the ultra-deepwater drillship Deepwater Aquila.  Additionally, in the year ended December 31, 2022, we made an aggregate cash contribution of $10 million to our equity investment in Orion, the company that, through its wholly owned subsidiary, owns the harsh environment floater Transocean Norge.  In June 2021, we agreed to participate in a financing arrangement for Orion, at a rate of 33 percent, equivalent to our ownership interest in Orion, and made a cash investment of $33 million in the loan facility. In February 2023, we agreed to make an investment for a noncontrolling ownership interest in Global Sea Mineral Resources, a Belgian company and leading developer of nodule collection technology, which is engaged in the development and exploration of deep-sea polymetallic nodules that contain metals critical to the growing renewable energy market.  In addition to a cash investment of $10 million, we agreed to contribute the ultra-deepwater drillship Ocean Rig Olympia, and we expect to contribute engineering services in the future. In the year ended December 31, 2022, we made an aggregate cash investment of $22 million in the equity and debt of certain other unconsolidated affiliates that are involved in researching and developing technology to improve efficiency, reliability, sustainability and safety in drilling and other activities.  We hold an equity investment in Nauticus, a company that develops highly sophisticated, ultra-sustainable marine robots and intelligent software to power them, which, following the completion of a business combination with a publicly traded special purpose acquisition company in September 2022, became a publicly listed company, the common shares of which trade on the NASDAQ exchange under the ticker symbol “KITT.”  Additionally, we hold equity and debt investments in Ocean Minerals LLC, the parent company of Moana Minerals Ltd. (“Moana”), a Cook Islands subsea resource development company that intends to extract polymetallic nodules.  We retain a priority right to provide deepwater nodule extraction services to Moana, and together with Moana and others, we intend to extract the nodules in an environmentally responsible way by employing existing and developing new technologies. Exchangeable bonds—The indentures that govern the 4.00% Senior Guaranteed Exchangeable Bonds, 2.50% senior guaranteed exchangeable bonds due January 2027 and the 4.625% Senior Guaranteed Exchangeable Bonds each requires such bonds to be repurchased upon the occurrence of certain fundamental changes and events, at specified prices depending on the particular fundamental change or event, which include changes and events related to certain (i) change of control events applicable to Transocean Ltd. or Transocean Inc., (ii) the failure of our shares to be listed or quoted on a national securities exchange and (iii) specified tax matters.  Additionally, the 4.00% Senior Guaranteed Exchangeable Bonds and the 4.625% Senior Guaranteed Exchangeable Bonds may be exchanged at any time prior to the close of business on the second business day immediately preceding the maturity date at the effective - 34 - Table of Contents exchange rate, and any such exchange may be settled in cash, Transocean Ltd. shares or a combination of cash and Transocean Ltd. shares, at our election. Share repurchase program—In May 2009, at our annual general meeting, our shareholders approved and authorized our board of directors, at its discretion, to repurchase for cancellation any amount of our shares for an aggregate purchase price of up to CHF 3.50 billion.  On February 12, 2010, our board of directors authorized our management to implement the share repurchase program.  At December 31, 2022, the authorization remaining under the share repurchase program was for the repurchase of our outstanding shares for an aggregate purchase price of up to CHF 3.24 billion, equivalent to $3.51 billion.  We intend to fund any repurchases using available cash balances and cash from operating activities.  The share repurchase program could be suspended or discontinued by our board of directors or company management, as applicable, at any time.  We may decide, based on our ongoing capital requirements, the price of our shares, regulatory and tax considerations, cash flow generation, the amount and duration of our contract backlog, general market conditions, debt rating considerations and other factors, that we should retain cash, reduce debt, make capital investments or acquisitions or otherwise use cash for general corporate purposes.  Decisions regarding the amount, if any, and timing of any share repurchases will be made from time to time based on these factors.  Any repurchased shares under the share repurchase program would be held by us for cancellation by the shareholders at a future general meeting of shareholders.  See “Item 5.

As of December 31, 2022, we had unrecognized tax benefits of $471 million, including interest and penalties, against which we recorded net operating loss deferred tax assets of $383 million, resulting in net unrecognized tax benefits of $88 million, including interest and penalties, that upon reversal would favorably impact our effective tax rate.  Although a portion of these could settle or reverse in the coming year, we have excluded this amount from our contractual obligations presented above due to the high degree of uncertainty regarding the timing of future cash outflows associated with these liabilities and the period in which any cash settlement may be made with the respective taxing authorities.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes. Other commercial commitments—We have other commercial commitments, such as standby letters of credit and surety bonds that guarantee our performance as it relates to our drilling contracts, insurance, customs, tax and other obligations in various jurisdictions.  The cash obligations of these commitments, which are primarily geographically concentrated in Brazil, are not normally called because we typically comply with the underlying performance requirements.  Standby letters of credit are issued under various committed and uncommitted credit lines, some of which require cash collateral.  At December 31, 2022, the aggregate cash collateral held by banks for letters of credit and surety bonds was $7 million.

In the year ended December 31, 2022, we made a cash contribution of $15 million to Liquila, which represented our proportionate contribution that was used to make the initial payment to the shipyard to acquire the newbuild ultra-deepwater drillship Deepwater Aquila for a purchase price of approximately $200 million.  The seventh generation, high-specification drillship is designed to be equipped with our patented dual activity, a 1,400 short-ton hookload, large deck space, high load capacities, large deck space and will be dual-stack ready.  We maintain the exclusive right to market and manage the operations of the rig, which is expected to be delivered from the shipyard in the third quarter of 2023.

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 with Orion for the operation, stacking and maintenance of the harsh environment floater Transocean Norge and a marketing services agreement for the marketing of the rig.  We also periodically lease the rig under short-term bareboat charter agreements.  In June 2021, Orion refinanced its shipyard loans under a financing arrangement for $100 million, in which we made a cash investment of $33 million.  Borrowings under the financing arrangement are secured by Transocean Norge.  Additionally, we have a management services agreement with Liquila for various services, including the marketing of - 36 - Table of Contents the newbuild ultra-deepwater drilliship Deepwater Aquila.  See Notes to Consolidated Financial Statements—Note 3—Unconsolidated Affiliates.

Critical Accounting Policies and Estimates Overview—We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the U.S., which require us to make estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities.  These estimates require significant judgments and assumptions.  On an ongoing basis, we evaluate our estimates, including those related to our income taxes, property and equipment, equity investments, contingencies, allowance for excess materials and supplies, intangibles, postemployment benefit plans 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 and accounting standards updates, refer to our Notes to Consolidated Financial Statements—Note 2—Significant Accounting Policies. Income taxes—We provide for income taxes based on expected taxable income, statutory rates, tax laws and tax planning opportunities available to us in the jurisdictions in which we operate or have a taxable presence.  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.  Consequently, our income tax expense does not change proportionally with our income or loss before income taxes. Uncertain tax positions—We apply significant judgment to evaluate our tax positions based on the interpretation of tax laws in various jurisdictions and with the use of estimates and assumptions regarding significant future events, such as the amount, timing and character of income, deductions and tax credits.  Our tax liability in any given year could be affected by changes in tax laws, regulations, agreements, and treaties, currency exchange restrictions or our level or profitability of operations in each jurisdiction.  The tax laws relating to the offshore drilling industry in certain jurisdictions in which we operate are not well developed, requiring us to apply incremental judgment.  Although we employ the best information available at the time we prepare our annual tax provision, a number of years may elapse before the tax liabilities in the various jurisdictions are ultimately determined. 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, and the provisions and benefits resulting from changes to those liabilities are included in our annual tax provision along with related 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, 2022 and 2021, we had unrecognized tax benefits of $471 million and $435 million, respectively, including interest and penalties, against which we recorded net operating loss deferred tax assets of $383 million and $320 million, respectively, resulting in net unrecognized tax benefits of $88 million and $115 million, respectively, including interest and penalties, that upon reversal would favorably impact our effective tax rate. Valuation allowance—We apply significant judgment to determine whether our deferred tax assets will be fully or partially realized.  Our evaluation requires us to consider all available positive and negative evidence, including projected future taxable income and the existence of cumulative losses in recent years.  We continually evaluate tax planning strategies that could allow for the future utilization of - 37 - Table of Contents 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.  During the years ended December 31, 2022 and 2021, in connection with our evaluation of the projected realizability of our deferred tax assets, we determined that our consolidated cumulative loss incurred over the recent three-year period has limited our ability to consider other subjective evidence, such as projected contract activity rather than contract backlog.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes. Property and equipment—We apply significant judgment to account for our property and equipment, consisting primarily of offshore drilling rigs and related equipment, related to estimates and assumptions for cost capitalization, useful lives and salvage values.  At December 31, 2022 and 2021, the carrying amount of our property and equipment was $17.47 billion and $17.10 billion, respectively, representing 85 percent and 83 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 for, the related assets, which also impact our results of operations. Useful lives and salvage values—We depreciate our assets using the straight-line method over their estimated useful lives after allowing for salvage values.  We estimate useful lives and salvage values by applying judgments and assumptions that reflect both historical experience and expectations regarding future operations, rig utilization and asset performance.  Useful lives and salvage values of rigs are difficult to estimate due to a variety of factors, including (a) technological advances that impact the methods or cost of oil and gas exploration and development, (b) changes in market or economic conditions and (c) changes in laws or regulations affecting the drilling industry.  Applying different judgments and assumptions in establishing the useful lives and salvage values would likely result in materially different net carrying amounts and depreciation expense for our assets.  We reevaluate the remaining useful lives and salvage values of our rigs when certain events occur that directly impact the useful lives and salvage values of the rigs, including changes in operating condition, functional capability and market and economic factors.  We may also consider major capital upgrades required to perform certain contracts and the long-term impact of those upgrades on future marketability.  At December 31, 2022, a hypothetical one-year increase in the useful lives of all of our rigs would cause a decrease in our annual depreciation expense of approximately $38 million and a hypothetical one-year decrease would cause an increase in our annual depreciation expense of approximately $13 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.  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 mobilize rigs from an oversupplied region to a more lucrative and undersupplied region when it is economical to do so.  Many of our contracts generally allow our customers to relocate our rigs from one geographic region to another, subject to certain conditions, and our customers utilize this capability to meet their worldwide drilling requirements.  Accordingly, our rigs are considered to be interchangeable within classes or asset groups, and we evaluate impairment by asset group.  We consider our asset groups to be ultra-deepwater floaters and harsh environment floaters. We assess recoverability of assets held and used by projecting undiscounted cash flows for the asset group being evaluated.  When the carrying amount of the asset group is determined to be unrecoverable, we recognize an impairment loss, measured as the amount by which the carrying amount of the asset group exceeds its estimated fair value.  To estimate the fair value of each asset group, we apply a variety of valuation methods, incorporating income, market and cost approaches.  We may 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 Level 3 fair value measurements, 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, 2020, we recognized a loss of $31 million, which had no tax effect, associated with the impairment of the midwater floater asset group.  See Notes to Consolidated Financial Statements—Note 6—Long-Lived Assets. Equity-method investments and impairment—We review 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, - 38 - Table of Contents 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 Level 3 fair value measurements, 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 years ended December 31, 2021 and 2020, we recognized a loss of $37 million and $59 million, respectively, associated with an other-than-temporary impairment of the carrying amount of our equity-method investments.  See Notes to Consolidated Financial Statements—Note 3—Unconsolidated Affiliates. Other Matters Regulatory matters We occasionally receive inquiries from governmental regulatory agencies regarding our operations around the world, including inquiries with respect to various tax, environmental, regulatory and compliance matters.  To the extent appropriate under the circumstances, we investigate such matters, respond to such inquiries and cooperate with the regulatory agencies.  See Notes to Consolidated Financial Statements—Note 12—Commitments and Contingencies. Tax matters We conduct operations through our various subsidiaries in countries throughout the world.  Each country has its own tax regimes with varying nominal rates, deductions and tax attributes that are subject to changes resulting from new legislation, interpretation or guidance.  From time to time, as a result of these changes, we may revise previously evaluated tax positions, which could cause us to adjust our recorded tax assets and liabilities.  Tax authorities in certain jurisdictions are examining our tax returns and, in some cases, have issued assessments.  We intend to defend our tax positions vigorously.  Although we can provide no assurance as to the outcome of the aforementioned changes, examinations or assessments, we do not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations; however, it could have a material adverse effect on our consolidated statement of cash flows.  See Notes to Consolidated Financial Statements—Note 10—Income Taxes.
