Note 1—Business

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells. ~~We specialize in technically demanding sectors~~As of the offshore drilling business with a particular focus on deepwater and harsh environment drilling services. Our mobile offshore drilling fleet is considered one of the most versatile fleets in the world. We contract our drilling rigs, related equipment and work crews predominantly on a dayrate basis to drill oil and gas wells. At SeptemberJune 30, ~~2017,~~2022, we owned or had partial ownership interests in and operated 38a fleet of 37 mobile offshore drilling units, ~~including 25 ultra‑deepwater~~consisting of 27 ultra-deepwater floaters ~~seven~~and 10 harsh environment ~~floaters, two deepwater floaters and four midwater~~ floaters. ~~At September~~As of June 30, ~~2017,~~2022, we ~~also had four ultra‑deepwater drillships under construction or under contract to be constructed.~~

On August 13, 2017, we entered into a transaction agreement (the “Transaction Agreement”) with Songa Offshore SE, a European public company limited by shares, or societas Europaea, existing under the laws of Cyprus (“Songa”), pursuant to which we will offer to acquire all of the issued and outstanding shares of Songa, subject to certain conditions, through a public voluntary exchange offer (the “Offer”). At September 30, 2017, Songa owned and operated seven mobile offshore drilling units, including four harsh environment floaters and three midwater floaters. See Note 4—Business Combination.

On May 31, 2017, we completed the sale of 10 high‑specification jackups and novated the contracts relating to the construction of five high‑specification jackups, together with related assets. At September 30, 2017 we continued to operate two high‑specification jackups that were ~~under contract when we sold the rigs, and we will continue to operate such rigs until completion or novation of the respective drilling contracts. See Note 6—Drilling Fleet.~~constructing 2 ultra-deepwater drillships.

Note 2—Significant Accounting Policies

Presentation—We ~~have~~ prepared our accompanying unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S.”) for interim financial information and with the instructions to Form ~~10‑Q~~10-Q and Article 10 of Regulation ~~S‑X~~S-X of the U.S. Securities and Exchange Commission. Pursuant to such rules and regulations, these financial statements do not include all disclosures required by accounting principles generally accepted in the U.S. for complete financial statements. The condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary for a fair presentation of financial position, results of operations and cash flows for the interim periods. Such adjustments are considered to be of a normal recurring nature unless otherwise noted. Operating results for the three and ~~nine~~six months ended ~~September~~June 30, ~~2017~~2022, are not necessarily indicative of the results that may be expected for the year ending December 31, ~~2017,~~2022, or for any future period. The accompanying condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto as of December 31, ~~2016~~2021 and ~~2015~~2020, and for each of the three years in the period ended December 31, ~~2016,~~2021, included in our annual report on Form ~~10‑K~~10-K filed on ~~March 7, 2017.~~February 23, 2022.

Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted in the U.S., we ~~are required to~~must make judgments by applying 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 income taxes, property and equipment, equity investments, contingencies, allowance for ~~doubtful accounts,~~excess materials and supplies, ~~obsolescence, property and equipment, assets held for sale, income taxes, contingencies, share‑based compensation, defined~~intangibles, postemployment benefit ~~pension~~ plans and ~~other postretirement benefits.~~share-based compensation. We base our estimates and assumptions on historical experience and ~~on various~~ other factors 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.~~reasonable. Actual results could differ from such estimates.

Fair value measurements—We estimate fair value at aan exchange price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market ~~participants in the principal market for the asset or liability.~~participants. Our valuation techniques require inputs that we categorize using a ~~three‑level~~three-level hierarchy, from highest to lowest level of observable inputs, as follows: (1) significant observable inputs, including unadjusted quoted prices for identical assets or liabilities in active markets (“Level 1”), (2) significant other observable inputs, including direct or indirect market data for similar assets or liabilities in active markets or identical assets or liabilities in less active markets (“Level 2”) and (3) significant unobservable inputs, including those that require considerable judgment for which there is little or no market data (“Level 3”). When a valuation requires multiple input levels, ~~are required for a valuation,~~ we categorize the entire fair value measurement according to the lowest level of input that is significant to the measurement even though we may have also utilized significant inputs that are more readily observable.

~~Capitalized interest~~Note 3—Unconsolidated Affiliates

Equity investments—We ~~capitalize~~hold noncontrolling equity investments in various unconsolidated companies, including (a) our 33.0 percent ownership interest ~~costs~~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, (b) our interests in certain companies that are involved in researching and developing technology to improve efficiency, reliability, sustainability and safety for ~~qualifying construction~~drilling and ~~upgrade projects~~other activities and ~~only capitalize~~(c) our interest ~~costs during periods~~ in ~~which progress for~~Ocean Minerals LLC, the ~~construction projects continues to be underway. As~~parent company of ~~September 30, 2017, we had ceased capitalization of interest costs on our two uncontracted newbuilds due~~Moana Minerals Ltd., a Cook Islands subsea resource development company that was recently awarded an exploration license by the Cook Islands Seabed Minerals Authority, granting it exploration rights to a ~~pause in construction progress.~~large subsea geographic area with substantial quantities of polymetallic nodules. In the ~~three and nine~~six months ended ~~September~~June 30, ~~2017,~~2022, we ~~capitalized interest costs~~made an aggregate cash contribution of ~~$31~~$19 million to our equity investments. At June 30, 2022 and December 31, 2021, the aggregate carrying amount of our equity investments was $103 million and $91 million, respectively, recorded in other assets, of which the aggregate carrying amount of our equity investment in Orion was $59 million and $57 million, respectively.

Related party transactions—We engage in certain related party transactions with unconsolidated affiliates, the most significant of which are under agreements with Orion. We operate, stack and maintain Transocean Norge under a management services agreement, and we market Transocean Norge under a marketing services agreement. We lease Transocean Norge under a short-term bareboat charter agreement, which is scheduled to expire in September 2022. Additionally, we procure and provide services and equipment from and to other unconsolidated affiliates for ~~construction work in progress.~~technological innovation and subsea minerals exploration. In the ~~three and nine~~six months ended ~~September~~June 30, ~~2016,~~2022 and 2021, we ~~capitalized interest costs~~received an aggregate cash payment of ~~$41~~$28 million and ~~$130~~$2 million, respectively, for ~~construction work~~services and equipment provided to Orion.

In June 2021, Orion refinanced its shipyard loans under a financing arrangement for $100 million, in ~~progress.~~

~~cash flows provided by or used in operating and financing activities, as applicable. For~~Dispositions—During the ~~nine~~six months ended ~~September~~June 30, ~~2017 and 2016, such changes would not have had a material effect on~~2021, in connection with our ~~condensed consolidated statements~~efforts to dispose of ~~cash flows.~~

~~Retirement benefits—Effective no later than January 1, 2018,~~non-strategic assets, we ~~will adopt~~completed 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 condensed consolidated statements of operations. The update also allows only the service cost component of net benefit cost to be eligible for capitalization. The update, which permits early adoption, is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. We do not expect that our adoption will have a material effect on our condensed consolidated statements of cash flows or on the disclosures contained in our notes to condensed consolidated financial statements.

~~Note 4—Business Combination~~

~~On August 13, 2017, we entered into the Transaction Agreement with Songa pursuant to which we will offer to acquire all~~sale of the ~~issued~~harsh environment floater Leiv Eiriksson and ~~outstanding shares~~related assets. In the six months ended June 30, 2021, we received aggregate net cash proceeds of ~~Songa. As part~~$4 million and recognized an aggregate net loss of ~~the Offer, we agreed to offer to exchange each of the issued and outstanding shares in Songa for consideration, based on a value of NOK 47.50 per Songa share, consisting of (i) 68.6~~$60 million ~~newly issued shares of Transocean Ltd., par value CHF~~ ($0.10 per ~~share, and (ii) approximately $575 million~~diluted share), which had 0 tax effect, associated with the disposal of these assets.

Note 6—Debt

Overview

Outstanding debt—The aggregate principal ~~amount~~amounts and aggregate carrying amounts, including the contractual interest payments of 0.5% Senior Unsecured Exchangeable Bonds to be issued by Transocean Inc. (the “Exchangeable Bonds”) exchangeable into shares of Transocean Ltd. Additionally, each Songa shareholder may elect to receive a cash payment of NOK 47.50 per Songa share up to a maximum of NOK 125,000 per shareholder in lieu of some or all of the considerationpreviously restructured debt and unamortized debt-related balances, such ~~shareholder would otherwise be entitled to receive in the Offer. The consideration,~~ as ~~presented in the Offer, is based on an equity value of Songa on a fully diluted basis of approximately NOK 9.1 billion~~discounts, premiums and an enterprise value of approximately NOK 26.4 billion, equivalent to approximately $1.2 billion and $3.4 billion, respectively, measured as of the date of the Offer using a currency exchange ratio of NOK 7.9239 to $1.00. We also expect to (i) acquire certain outstanding bonds issued by Songa in exchange for Exchangeable Bonds, and (ii) acquire a $50 million loan made to Songa by one of its shareholders in exchange for Exchangeable Bonds. The consummation of the Offer is subject to the satisfaction of customary closing conditions for transactions of this type.

The Exchangeable Bonds will have an exchange ratio equal to 0.7145 times, determined as of the date of the Offer, based on the market price of $8.39 per Transocean Ltd. share and a currency exchange ratio of NOK 7.9239 to $1.00 . The Exchangeable Bonds will mature five years from the date of issuance. Interest is expected to be paid semiannually at 0.5% per annum.

We expect to complete the transaction before December 31, 2017. If completed, we will account for the transaction using the acquisition method of accounting, pursuant to which we will record the consideration transferred, the assets acquired and the liabilities assumed at fair value, measured as of the acquisition date.

Credit agreements

~~Impairments of assets held and used~~Secured Credit Facility—~~During the three months ended~~At June 30, ~~2017,~~2022, we ~~identified indicators~~had a $1.33 billion secured revolving credit facility established under a bank credit agreement (as amended from time to time, the “Secured Credit Facility”), which was scheduled to mature on June 22, 2023. The Secured Credit Facility is guaranteed by Transocean Ltd. and certain wholly owned subsidiaries. We may borrow under the Secured Credit Facility at either (1) the reserve adjusted London Interbank Offered Rate plus a margin (the “Secured Credit Facility Margin”), which ranges from 2.625 percent to 3.375 percent based on the credit rating of the Secured Credit Facility, or (2) the base rate specified in the credit agreement plus the Secured Credit Facility Margin, minus 1 percent per annum. Throughout the term of the Secured Credit Facility, we pay a facility fee on the amount of the underlying commitment, which ranges from 0.375 percent to 1.00 percent based on the credit rating of the Secured Credit Facility. At June 30, 2022, based on the credit rating of the Secured Credit Facility on that date, the ~~asset groups in our contract drilling services reporting unit may not be recoverable. Such indicators included recent significant declines in commodity prices~~Secured Credit Facility Margin was 3.375 percent and the ~~market value~~facility fee was 0.875 percent. At June 30, 2022, we had 0 borrowings outstanding, $9 million of letters of credit issued, and we had $1.32 billion of available borrowing capacity under the Secured Credit Facility.

In July 2022, we amended the bank credit agreement for our ~~stock,~~Secured Credit Facility to, among other things, (i) extend the maturity date from June 22, 2023 to June 22, 2025, subject to permitted extensions and certain early maturity triggers, (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 the Secured Credit Facility Margin with the ability to borrow under the Secured Credit Facility at a ~~reduction of projected dayrates~~forward-looking term rate based on the secured overnight financing rate (“Term SOFR”) plus the Secured Credit Facility Margin and a ~~further extension~~Term SOFR spread adjustment of ~~currently low utilization rates. As~~0.10 percent.

The Secured Credit Facility contains covenants that, among other things, requires that we maintain minimum liquidity of $500 million. In order to remain in compliance with the requirement and to avoid a ~~result~~default under our Secured Credit Facility, we must obtain additional liquidity of at least $330 million within the 12-month period following the issuance of the financial statements included in this report, which we plan to obtain through a secured financing for Deepwater Titan. A failure by us to avoid such a default would eliminate our ~~testing,~~access to incremental borrowing under the Secured Credit Facility and, since we ~~determined~~expect to access borrowings under the Secured Credit Facility, give our lenders the right to declare such borrowings immediately due and payable. Although not assured, we believe it is probable that we will be able to obtain such secured financing for Deepwater Titan in the required timeframe.

Shipyard financing arrangement—In June 2021, we entered into credit agreements with Jurong Shipyard Pte Ltd. establishing facilities (each, a “Shipyard Loan,” and together, 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 the Shipyard Loan and made a cash payment of $46 million to satisfy the final milestone payment due upon delivery of Deepwater Atlas. We recorded the Shipyard Loan, net of imputed interest, and corresponding non-cash capital additions of $300 million, recorded in property and equipment. The carrying amount of the midwater floater asset group was impaired. In the nine months ended September 30, 2017, we recognized a loss of $94 million ($95 million, after taxes, or $0.25 per diluted share), associated with the impairment of the midwater floater asset group. We measured the fair value of this asset group by applying a combination of income and market approaches, using projected discounted cash flows and estimates of the exchange price that would be received for the assets in the principal or most advantageous markets for the assets in an orderly transaction between participants as of the measurement date. Our estimate of fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of our contract drilling services reporting unit, such as future commodity prices, projected demand for our services, rig availability and dayrates.

~~Impairments of assets held for sale~~—In the three months ended September 30, 2017, we recognized an aggregate loss of $1.4 billion ($3.54 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~~ ~~and the deepwater floater~~ ~~Transocean Marianas, along with related assets, which were classified as held for sale~~Shipyard Loan at the time of impairment. In the nine months ended September 30, 2017, we recognized an aggregate loss of $1.4 billion ($3.60 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 were classified as held for sale at the time of impairment.~~

In the three months ended September 30, 2016, we recognized an aggregate loss of $11 million ($0.03 per diluted share), which had no tax effect, associated with the impairment of the midwater floaters ~~Transocean Driller~~ ~~and~~ ~~Transocean Winner,~~ along with related assets, which were held for sale at the time of impairment. In the nine months ended September 30, 2016, we recognized an aggregate loss of $26 million ($25 million, net of tax, or $0.06 per diluted share) associated with the impairment of the deepwater floater ~~Sedco 702~~ ~~and the midwater floaters~~ ~~Transocean Driller~~, ~~Transocean John Shaw~~ ~~and~~ ~~Transocean Winner, along with related assets, which were classified as held for sale at the time of impairment.~~

~~We measured the impairment of the drilling units and related assets as the amount by which the carrying amount exceeded the~~inception represented its estimated fair value ~~less costs to sell. We estimated the fair value of the assets~~ using significant other observable inputs, representative of Level 2 fair value measurements, including ~~indicative market values~~the terms and credit spreads of our debt, by applying an estimated discount rate of 9.4 percent. At June 30, 2022, we had no borrowings outstanding under the Shipyard Loan forDeepwaterTitan.

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. In certain circumstances, borrowings under the Shipyard Loan for Deepwater Titan may also be secured by, among other security, a lien on the rig. We will repay the borrowings under the Shipyard Loan for Deepwater Atlas, together with interest of 4.5 percent per annum, in installments through June 2027. 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, limit the ability of the subsidiary owners of the drilling ~~units and related assets~~rigs to ~~be sold for scrap value~~incur certain types of additional indebtedness or ~~alternative use. If we commit to plans to sell~~make certain additional ~~rigs for values below the respective carrying amounts~~commitments or commit to plans to recycle additional rigs and sell them for scrap value, we may be required to recognize additional losses associated with the impairment of such assets. Such losses could be material.

~~Dispositions—On May 31, 2017, in connection with our efforts to dispose of non‑strategic assets, we completed the sale of 10 high‑specification jackups, including~~ ~~GSF Constellation I, GSF Constellation II, GSF Galaxy I, GSF Galaxy II, GSF Galaxy III, GSF Monarch, Transocean Andaman, Transocean Ao Thai, Transocean Honor~~ ~~and~~ ~~Transocean Siam Driller~~, along with related assets, and novated the contracts relating to the construction of five high‑specification jackups, together with related assets. In the nine months ended September 30, 2017, we received aggregate net cash proceeds of $319 million and recognized an aggregate net loss of $1.6 billioninvestments.

Note 7—Income Taxes

Tax provision and rate—Transocean Ltd., a holding company and Swiss resident, is exempt from cantonal and communal income tax in Switzerland, but is subject to Swiss federal income tax. 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 ~~nine~~six months ended ~~September~~June 30, ~~2017~~2022 and ~~2016,~~2021, our ~~estimated~~ effective tax rate ~~excluding discrete items,~~ was ~~64.2~~(13.7) percent and ~~25.9~~7.7 percent, respectively, based on ~~estimated annual income from continuing operations~~loss before income ~~taxes. Our effective~~ tax ~~rate increased in~~expense or benefit. In the ~~nine~~six months ended ~~September~~June 30, ~~2017, compared to the nine months ended September 30, 2016, primarily due to (a) changes in the relative blend of income from operations in certain jurisdictions~~2022 and ~~(b) valuation allowances on deferred tax assets not expected to be realized.~~

We consider the tax effect, if any, of the excluded items as well as settlements of prior year tax estimates to be discrete period tax expenses or benefits. In the nine months ended September 30, 2017 and 2016,2021, the effect of ~~the~~ various discrete period tax items was a net tax benefit of ~~$57~~$8 million and ~~$24~~$33 million, ~~respectively.~~respectively, and the reduction of such tax benefit was primarily due to reduced releases of uncertain tax positions in the current-year period. In the ~~nine~~six months ended ~~September~~June 30, ~~2017,~~2022, such discrete items ~~were primarily related to tax benefit~~included expiration of ~~changes in unrecognized tax benefit associated with~~various uncertain tax positions ~~taken in prior years,~~and changes to valuation ~~allowances on deferred tax assets not expected to be realized, and deductions related to resolution of certain litigation matters related to the Macondo well incident.~~allowances. In the ~~nine~~six months ended ~~September~~June 30, ~~2016,~~2021, such discrete items ~~were primarily related to~~included loss on disposal of assets, gain on retirement of debt and expiration and settlement of various uncertain tax ~~benefit of changes in unrecognized tax benefit associated with tax positions taken in prior years and valuation allowances on deferred tax assets for losses not expected to be realized. For~~positions. In the ~~nine~~six months ended ~~September~~June 30, ~~2017~~2022 and ~~2016, these discrete tax items, coupled with the excluded income and expense items noted above, resulted in an~~2021, our effective tax rate, ~~of (3.6)~~excluding discrete items, was (17.5) percent and ~~17.8~~(7.8) percent, respectively, based on ~~income from continuing operations~~loss before income tax ~~expense.~~expense or benefit.

~~In evaluating our ability to realize deferred tax assets, we consider all available positive~~Tax positions and negative evidence, including projected future taxable income and the existence of cumulative losses in recent years. As of September 30, 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 a valuation allowance of $144 million to recognize only a portion of our U.S. deferred tax assets that are more likely than not to be recognized. If estimated future taxable income changes during the carryforward periods or if the cumulative loss is no longer present, we may adjust the amount of deferred tax assets that we expect to realize.

~~Tax~~ returns—We ~~file federal and local tax returns~~conduct operations through our various subsidiaries in ~~several jurisdictions~~countries throughout the world. ~~With few exceptions, we~~Each country has its own tax regimes with varying nominal rates, deductions and tax attributes that are ~~no longer~~ subject to ~~examinations~~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 ~~U.S.~~recorded tax assets and non‑U.S. tax matters for years prior to 2010. Our tax returns in the major jurisdictions in which we operate, other than Brazil, as mentioned below, are generally subject to examination for periods ranging from three to six years.

~~jurisdictions. While~~vigorously. Although we ~~cannot predict or~~can provide no assurance as to the ~~timing or the~~ outcome of ~~these proceedings,~~the aforementioned changes, examinations or assessments, we do not expect the ultimate liability to have a material adverse effect on our condensed consolidated statement of financial position or results of ~~operations, although~~operations; however, it ~~may~~could have a material adverse effect on our condensed consolidated statement of cash flows.

Brazil tax investigations—In December 2005, the Brazilian tax authorities ~~issued a~~began issuing tax ~~assessment~~assessments with respect to our tax returns for the years 2000 through 2004, which is currently for an aggregate amount of BRL 846 million, equivalent to approximately $267 million, including penalties and interest. On January 25, 2008, we filed a protest letter with the Brazilian tax authorities for this tax assessment, and we are currently engaged in the appeals process. On2004. In May ~~19,~~ 2014, the Brazilian tax authorities issued aan additional tax assessment ~~with respect to our Brazilian income tax returns~~ for the years 2009 and ~~2010, which is currently for an aggregate amount of BRL 144 million, equivalent to approximately $46 million, including penalties~~2010. We are actively engaged in the appeals process and ~~interest. On June 18, 2014, we~~have filed ~~a protest letter~~protests with the Brazilian tax authorities, which has resulted in favorable closure of a portion of the two cases. As of June 30, 2022, the remaining aggregate tax assessment, including interest and penalties, was for ~~this~~corporate income tax ~~assessment.~~of BRL 652 million, equivalent to approximately $124 million, and indirect tax of BRL 113 million, equivalent to approximately $21 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 in a material adverse effect on our condensed consolidated statement of financial position, results of operations or cash flows.~~

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

~~Interest rate adjustments~~—The interest rates for certain of our notes are subject to adjustment from time to time upon a change to our credit rating of our non‑credit enhanced senior unsecured long‑term debt (“Debt Rating”). As of September 30, 2017, based on the Debt Rating in effect on that date, the interest rate in effect for the 2.50% Senior Notes due October 2017 and the 3.80% Senior Notes due October 2022 was 4.50 percent and 5.80 percent, respectively, and the interest rate in effect for the 6.375% Senior Notes due December 2021 and the 7.35% Senior Notes due December 2041 was 8.375 percent and 9.35 percent, respectively.

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

We may borrow under the Five‑Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate plus a margin (the “Five‑Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the Debt Rating, or (2) the base rate specified in the credit agreement plus the Five‑Year Revolving Credit Facility Margin, less one percent per annum. Throughout the term of the Five‑Year Revolving Credit Facility, we pay a facility fee on the daily unused amount of the underlying commitment which ranges from 0.15 percent to 0.35 percent based on our Debt Rating. At September 30, 2017, based on our Debt Rating on that date, the Five‑Year Revolving Credit Facility Margin was 2.0 percent and the facility fee was 0.35 percent. At September 30, 2017, we had no borrowings outstanding or letters of credit issued, and we had $3.0 billion of available borrowing capacity under the Five‑Year Revolving Credit Facility.

~~Note 11—Commitments and Contingencies~~

~~Macondo well incident commitments and contingencies~~

~~Overview—On April 22, 2010, the ultra‑deepwater floater~~ ~~Deepwater Horizon~~ ~~sank after a blowout of the Macondo well caused a fire and explosion on the rig off the coast of Louisiana. At the time of the explosion,~~ ~~Deepwater Horizon~~ was contracted to an affiliate of BP plc (together with its affiliates, “BP”). Following the incident, we have been subject to civil and criminal claims, as well as causes of action, fines and penalties by local, state and federal governments. Litigation commenced shortly after the incident, and most claims against us were consolidated by the U.S. Judicial Panel on Multidistrict Litigation and transferred to the U.S. District Court for the ~~Eastern~~Southern District of ~~Louisiana~~New York (the ~~“MDL~~“Trial Court”) related to such certain internal reorganization transactions and the 2020 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 alleged default with respect to the indentures governing, respectively, the 8.00% senior notes due February 2027 (the “8.00% Senior Notes”) and the 7.25% senior notes due November 2025 (the “7.25% Senior Notes”). ~~A significant portion~~The facts alleged in the purported notice of default under the ~~contingencies arising from~~8.00% Senior Notes were the ~~Macondo well incident has now been resolved~~same as ~~a result~~the facts underlying the Claim and the purported notice of ~~settlements~~default under the 7.25% Senior Notes.

On September 23, 2020, we filed an answer to the Claim with the Trial 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% Senior 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 Trial 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 Trial 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% Senior Notes. Whitebox subsequently appealed the Trial Court’s ruling, and on February 1, 2022, the U.S. ~~Department~~Court of ~~Justice~~Appeals for the Second Circuit (the ~~“DOJ”~~“Second Circuit”)~~, BP~~ dismissed the appeal filed by Whitebox as moot and remanded to the ~~states of Alabama, Florida, Louisiana, Mississippi, and Texas. Additionally, we and~~Trial Court, which then dismissed the ~~Plaintiff Steering Committee (the “PSC”) entered into a settlement agreement (the “PSC Settlement Agreement”), which was approved~~claims as moot pursuant to the ruling by the ~~MDL Court on February 15, 2017.~~

~~We have recognized a liability for~~Second Circuit. Whitebox did not appeal 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 September 30, 2017 and December 31, 2016, the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $244 million and $250 million, respectively, recorded in other current liabilities. The remaining litigation could result in certain loss contingencies that we believe are reasonably possible. Although we have not recognized a liability for such loss contingencies, these contingencies could result in liabilities that we ultimately recognize.

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

~~Plea Agreement~~—Pursuant to the plea agreement (the “Plea Agreement”), one of our subsidiaries pled guilty to one misdemeanor count of negligently discharging oil into the U.S. Gulf of Mexico, in violation of the Clean Water Act and agreed to be subject to probation through February 2018. The DOJ agreed, subject to the provisions of the Plea Agreement, not to further prosecute us

~~(Unaudited)~~

~~for certain matters arising from the Macondo well incident. We also agreed to make an aggregate cash payment of $400~~ million, including a criminal fine and cash contributions to the National Fish & Wildlife Foundation and the National Academy of Sciences. At December 31, 2016, the carrying amount of our liability for such settlement obligations was $60 million, recorded in other current liabilities. In the nine months ended September 30, 2017 and 2016, we made cash payments of $60 million in each period, representing the final installments for our obligations under the Plea Agreement.

~~PSC Settlement Agreement~~—On May 29, 2015, together with the PSC, we filed the PSC Settlement Agreement with the MDL Court for approval. Through the PSC Settlement Agreement, we agreed to pay a total of $212 million, plus up to $25 million for partial reimbursement of attorneys’ fees, to be allocated between two classes of plaintiffs as follows: (1) private plaintiffs, businesses, and local governments who could have asserted punitive damages claims against us under general maritime law (the “Punitive Damages Class”); and (2) private plaintiffs who previously settled economic damages claims against BP and were assigned certain claims BP had made against us (the “Assigned Claims Class”). A court‑appointed neutral representative established the allocation of the settlement payment to be 72.8 percent paid to the Punitive Damages Class and 27.2 percent paid to the Assigned Claims Class. In exchange for these payments, each of the classes agreed to release all respective claims it has against us. Members of the Punitive Damages Class were given the opportunity to opt out, and 30 claimants have elected to opt out, of the PSC Settlement Agreement. In June 2016 and August 2015, we made a cash deposit of $25 million and $212 million, respectively, into escrow accounts pending approval of the settlementruling by the MDL Court. 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. At September 30, 2017 and December 31, 2016, the aggregate cash balance in escrow accounts was $237 million, recorded in restricted cash.Second Circuit.

~~Pending claims~~—As of September 30, 2017, numerous complaints remain pending against us, along with other unaffiliated defendants in the MDL Court. We believe our settlement with the PSC resolves many of these pending actions. As for any actions not resolved by these settlements, including any claims by individuals who opted out of the PSC Settlement Agreement, claims by the Mexican government under the Oil Pollution Act of 1990 and maritime law and federal securities law, we are vigorously defending those claims and pursuing any and all defenses available. See “—PSC Settlement Agreement.”

~~Insurance coverage~~—At the time of the Macondo well incident, our excess liability insurance program offered aggregate insurance coverage of $950 million, excluding a $15 million deductible and a $50 million self-insured layer through our wholly owned captive insurance subsidiary. This excess liability insurance coverage consisted of a first and a second layer of $150 million each, a third and fourth layer of $200 million each and a fifth layer of $250 million. We recovered costs under the first four excess layers, the limits of which are now fully exhausted. We submitted claims to the $250 million fifth layer, which is comprised of four Bermuda market insurers (the “Bermuda Insurers”). In the nine months ended September 30, 2017 and the year ended December 31, 2016, we received cash proceeds of $10 million and $20 million, respectively, associated with settlements with two of the Bermuda Insurers. We are in the early stages of arbitration with one of the Bermuda Insurers. We cannot provide assurance that we will successfully recover additional proceeds under the policy limits with the Bermuda Insurers.

~~Other legal proceedings~~

Asbestos litigation—In 2004, several of our subsidiaries were named, along with numerous other unaffiliated defendants, in 21 complaints filed ~~on behalf of 769 plaintiffs~~ in the Circuit Courts of the State of Mississippi, and 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‑~~court appointed special master has ruled that a Jones Act employer defendant, such as us, cannot be sued for punitive damages. ~~At September~~One of our subsidiaries was named in additional complaints filed in Illinois and Missouri, where the plaintiffs similarly allege that the defendants manufactured asbestos containing products or used asbestos-containing drilling mud additives in connection with land-based drilling operations. As of June 30, ~~2017, 15~~2022, 8 plaintiffs have claims pending in ~~Mississippi~~Louisiana and ~~eight~~15 plaintiffs in the aggregate have claims pending in ~~Louisiana~~either Illinois or Missouri, 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~~can provide no assurance as to 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 condensed consolidated statement of financial position, results of operations or cash flows.

One of our subsidiaries ~~has been~~was 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 ~~September~~June 30, ~~2017,~~2022, the subsidiary was a defendant in approximately ~~123~~239 lawsuits with a corresponding number of plaintiffs. For many of these lawsuits, we have not been provided ~~with~~ sufficient information from the plaintiffs to determine whether all or some of the plaintiffs have claims against the subsidiary, the basis of any such claims, or the nature of their alleged injuries. The operating assets of the subsidiary were sold in 1989. In December 2021, the subsidiary and ~~its operations were discontinued~~certain insurers agreed to a settlement of outstanding disputes that provide the subsidiary with cash. An earlier settlement in ~~1989,~~September 2018 provided the subsidiary with cash and an annuity that begins making payments in 2024. Together with a coverage in place agreement with certain insurers and additional coverage issued by other insurers, we believe the subsidiary has no remaining assets other than insurance policies, rights and proceeds, including (i) certain policies subject to litigation and (ii) certain rights and proceeds held directly or indirectly through a qualified settlement fund. The subsidiary has in excess of $1.0 billion in insurance limits potentially available to the subsidiary. Although not all of the policies may be fully available due to the insolvency of certain insurers, we believe that the subsidiary will have sufficient ~~funding directly or indirectly,~~

~~including from settlements and payments from insurers, assigned rights from insurers and coverage‑in‑place settlement agreements with insurers~~resources to respond to ~~these claims.~~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 condensed consolidated statement of financial position, results of operations or cash flows.

~~Rio de Janeiro tax assessment~~—In the year ended December 31, 2006, the state tax authorities of Rio de Janeiro in Brazil issued to one of our subsidiaries tax assessments on equipment imported into the state in connection with our operations, resulting from a preliminary finding by these authorities that our record keeping practices were deficient. At September 30, 2017, the aggregate tax assessment was for BRL 525 million, equivalent to approximately $166 million, including interest and penalties. In September 2006, we filed an initial response refuting these tax assessments, and, in September 2007, the state tax authorities confirmed that they believe the tax assessments are valid. On September 27, 2007, we filed an appeal with the state Taxpayer’s Council contesting the assessments. While we cannot predict or provide assurance as to the final outcome of these proceedings, we do not expect it to have a material adverse effect on our condensed consolidated statement of financial position, results of operations or cash flows.

~~Nigerian Cabotage Act litigation~~—In October 2007, three of our subsidiaries were each served a Notice and Demand from the Nigeria Maritime Administration and Safety Agency, imposing a two percent surcharge on the value of all contracts performed by us in Nigeria pursuant to the Coastal and Inland Shipping (Cabotage) Act 2003 (the “Cabotage Act”). Our subsidiaries each filed an originating summons in the Federal High Court in Lagos challenging the imposition of this surcharge on the basis that the Cabotage Act and associated levy is not applicable to drilling rigs. The respondents challenged the competence of the suits on several procedural grounds. The court upheld the objections and dismissed the suits. In December 2010, our subsidiaries filed a new joint Cabotage Act suit. While we cannot predict or provide assurance as to the outcome of these proceedings, we do not expect the proceedings to have a material adverse effect on our condensed 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 condensed consolidated statement of financial position, results of operations or cash flows. We cannot predict with certainty the outcome or effect of any of the litigation matters specifically described above or of any such other pending, threatened, or possible litigation or liability. We can provide no assurance that our beliefs or expectations as to the outcome or effect of any ~~tax,~~ regulatory, lawsuit or other litigation matter will prove correct, and the eventual outcome of these matters could materially differ from management’s current estimates.

~~Other environmental~~Environmental matters

~~Hazardous waste disposal sites~~—We have certain potential liabilities under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and similar state acts regulating cleanup of 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.

~~We have been~~One of our subsidiaries was named as a PRP in connection with a site located in Santa Fe Springs, California, known as the Waste Disposal, Inc. site. We and other PRPs ~~have~~ agreed, under a participation agreement with the U.S. Environmental Protection Agency (the “EPA”) and the ~~DOJ~~U.S. Department of Justice, to settle our potential liabilities by remediating the site. The remedial action for ~~this~~the site by agreeing to perform the remaining remediation required by the EPA. The parties to the settlement have entered into a participation agreement, which makes us liable for approximately eight percent of the remediation and related costs. The remediation is complete, and we believe ourwas completed in 2006. Our share of the ~~future operation~~ongoing operating and maintenance costs ~~of the site is~~has been insignificant, and we do not ~~material. There are~~expect any additional potential liabilities ~~related~~ to ~~the site, but these cannot be quantified, and we have no reason at this time to believe that they will~~ be material.

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

Resolutions of other claims by the EPA, the involved state agency or PRPs are at various stages of investigation. These investigations involve determinations of (a) the actual responsibility attributed to us and the other PRPs at the site, (b) appropriate investigatory or remedial actions and (c) allocation of the costs of such activities among the PRPs and other site users. Our ultimate financial responsibility in connection with those sites may depend on many factors, including (i) the volume and nature of material, if any, contributed to the site for which we are responsible, (ii) the number of other PRPs and their financial viability and (iii) the remediation methods and technology to be used.

Note ~~12—Shareholders’~~ 10—Equity

~~Par value reduction~~Share issuance—We maintain an at-the-market equity offering program (the “ATM Program”). We intend to use the net proceeds from our ongoing 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. On ~~October 29, 2015, at our extraordinary general meeting, our shareholders approved~~June 14, 2021, we entered into an equity distribution agreement with a sales agent for the ~~reduction of the par value of each~~offer and sale of our shares, ~~to CHF 0.10 from the original par value of CHF 15.00. The reduction of par value became effective as of January 7, 2016, upon registration in the commercial register.~~

~~Shares held in treasury—In May 2009, at our annual general meeting, our shareholders approved and authorized our board of directors, at its discretion, to repurchase an amount of our shares for cancellation~~ with ana maximum aggregate ~~purchase~~net offering price of up to ~~CHF 3.5 billion, equivalent to approximately $3.6 billion.

~~Shares held by subsidiaries~~—Two of our subsidiaries hold our shares for future use to satisfy our obligations to deliver shares in connection with awards granted under our incentive plans or other rights to acquire our shares. At September 30, 2017 and December 31, 2016, our subsidiaries held 3.6 million shares and 5.4 million shares, respectively.

Cash and cash equivalents—Our 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, which approximates fair value because of the short maturities of ~~those~~the instruments. We measured the estimated fair value of our cash equivalents using significant other observable inputs, representative of a Level 2 fair value measurement, including the net asset values of the investments.

~~Note 14—Subsequent events~~

~~Debt issuance~~—On October 17, 2017, we completed an offering of an aggregate principal amount of $750 million of 7.50% senior unsecured notes due January 15, 2026 (the “7.50% Senior Notes”), and we received aggregate cash proceeds of $742 million, net of issue costs. We intend to use the majority of the net proceeds from the debt offering to repay or redeem certain maturing debt. The 7.50% Senior Notes are fully and unconditionally guaranteed by Transocean Ltd. and certain wholly owned subsidiaries of Transocean Inc. Such notes rank equal in right of payment to all of our existing and future unsecured unsubordinated obligations and rank structurally senior to the extent of the value of the assets of the subsidiaries guaranteeing the notes. We will pay interest on the 7.50% Senior Notes semiannually on January 15 and July 15 of each year, beginning on July 15, 2018. We may redeem all or a portion of the 7.50% Senior Notes at any time prior to January 15, 2021 at a price equal to 100 percent of the aggregate principal amount plus a make‑whole provision, and on or after January 15, 2021, at specified redemption prices. The indenture that governs the 7.50% Senior Notes contains covenants that, among other things, limit our ability to incur certain liens on our drilling units without equally and ratably securing the notes, engage in certain sale and lease‑back transactions covering any of our drilling units, allow our subsidiaries to incur certain additional debt, and consolidate, merge or enter into a scheme of arrangement qualifying as an amalgamation.

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 ~~October 24, 2017,~~July 25, 2022, we owned or had partial ownership interests in and operated 3937 mobile offshore drilling units, ~~including 26 ultra‑deepwater~~consisting of 27 ultra-deepwater floaters ~~seven~~and 10 harsh environment ~~floaters,~~floaters. As of July 25, 2022, we were constructing two deepwater floaters and four midwater floaters. Additionally, we operated two high‑specification jackups that were under contract when we sold the rigs, and we continue to operate such rigs until completion or novation of the respective drilling contracts. At October 24, 2017, we also had three ultra‑deepwater drillships under construction or under contract to be constructed. See “—Significant Events.”ultra-deepwater drillships.

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

~~Our~~We perform contract drilling services ~~operations are~~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~~rig-moving vessels may cause the supply and demand balance to fluctuate somewhat between regions. Still, significant variations between regions do not tend to persist long term because of rig mobility. ~~Our fleet operates in a single, global market for the provision of contract drilling services.~~ The location of our rigs and the allocation of resources to operate, build or upgrade our rigs are determined by the activities and needs of our customers.

~~Dispositions~~—On May 31, 2017, we completed the sale of 10 high‑specification jackups and novated the contracts relating to the construction of five high‑specification jackups, together with related assets. In the nine months ended September 30, 2017, as a result of the transaction, we received aggregate net cash proceeds of $319 million and recognized an aggregate net loss of $1.6 billion associated with the disposal of these assets. See “—Operating Results” and “—Liquidity and Capital Resources—Drilling Fleet.”

~~Impairments~~—During the nine months ended September 30, 2017, we recognized a loss of $1.4 billion associated with the impairment of five ultra‑deepwater floaters, one deepwater floater and two midwater floaters, along with related assets, which were classified as held for sale at the time of impairment. See “—Operating Results” and “—Liquidity and Capital Resources—Drilling Fleet.”

~~During the three~~six months ended June 30, 2017, we identified indicators that the asset groups in our contract drilling services reporting unit may not be recoverable. As a result of our testing, we determined that the carrying amount of the midwater floater asset group was impaired. In the nine months ended September 30, 2017, we recognized a loss of $94 million, associated with the impairment of the midwater floater asset group. See “—Operating Results.”

~~Debt issuances—On October 17, 2017, we completed an offering of an aggregate principal amount of $750 million of 7.50% senior unsecured notes due January 2026 (the “7.50% Senior Notes”), and~~2022, we received aggregate cash proceeds of ~~$742~~$206 million, net of issue ~~costs.

We received valid tenders from holders of $1.2 billion aggregate principal amount of the 2017 Tendered Notes. As a result, we made an aggregate cash payment of $1.3 billion and recognized an aggregate net loss of $48 million associated with the retirement of such debt, validly tendered on or before the expiration date of the 2017 Tender Offers. See “—Liquidity and Capital Resources—Sources and uses of liquidity.”

During the nine months ended September 30, 2017, we completed transactions to repurchase in the open market an aggregate principal amount of $147 million of our debt securities for an aggregate cash payment of $147 million. As a result, in the nine months ended September 30, 2017, we recognized an aggregate net loss of $1 million associated with the retirement of such repurchased debt. See “—Liquidity and Capital Resources—Sources and uses of liquidity.”

Outlook

Drilling market—Our ~~long‑term view~~outlook remains 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 significant underinvestment in reserve replacement by oil and gas producers, the natural decline in production of existing oil and gas fields, and additional constraints imposed on industry participants by oil and gas producing nations and investors. Additionally, the Russian invasion of Ukraine and the related economic sanctions, have initiated renewed interest in energy security across Europe and the U.S. Due to these and other factors, oil prices have increased materially over the past two years and recently reached 10-year highs as reported by the New York Mercantile Exchange.

Recently, the price for both prompt and longer-dated barrels have exhibited volatility that reflects market concerns about inflationary trends, economic recession and the potential for demand destruction. However, they are currently, and are expected to remain, at levels that are robustly supportive of investment in deepwater exploration and development projects. Consequently, our outlook for the offshore drilling ~~market~~industry overall remains positive, ~~especially~~but 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, certain of which have initiated increased exploration, production and ~~ultra‑deepwater floaters.~~reserve replacement activities by restarting delayed projects and commencing new drilling campaigns. Licensing activity also indicated an increased interest in these areas as energy companies look to explore and develop new prospects. This has resulted in increasing tendering activity, including several multi-year tenders for Brazil, West Africa, Asia and Australia in the first half of 2022. We have recently observed that the commencement of our customers new projects is being, in some cases, influenced by global supply chain constraints such that it adversely impacts their ability to timely secure necessary equipment and supplies. We currently believe that these circumstances, to some degree, could persist for the next 12 to 18 months.

Table of Contents

Offshore drilling activity is increasing in almost every ultra-deepwater market, and due to the attrition of the global offshore fleet over the last several years, there are significantly fewer drilling units available to meet customer demands and, particularly, an increasing scarcity of the highest specification drilling units as customers look to secure the best equipment for their projects. South America, the U.S. Gulf of Mexico and, increasingly, West Africa remain key ultra-deepwater market sectors, while Norway continues to represent the largest harsh environment market. We have seen significant increases in dayrates for projects in the U.S. Gulf of Mexico, a trend that we expect will continue. In the Norwegian harsh environment market, we do not expect many new projects to commence in 2022, but we believe this market will significantly accelerate starting in 2023 through 2026 due to the Norwegian tax incentive programs. We are also encouraged by the recent ~~months, oil prices have stabilized at about $50 per barrel and have approached $60 per barrel, improving our customers’ economics~~announcements in the United Kingdom of ~~drilling~~new licensing for North Sea oil and gas ~~wells. This is, in large part, due~~projects, which could lead to ~~favorable trends in the hydrodcarbon supply‑demand balance: oil supply has declined relative to demand.~~

~~Improved oil prices have resulted in increased opportunities for our drilling services. In markets requiring harsh environment floating drilling~~some rigs ~~such as~~mobilizing from the Norwegian ~~North Sea,~~market to capture this demand, thereby reducing rig supply and potentially increasing dayrates for the ~~limited supply~~assets remaining in Norway.

We expect global energy demand to continue to increase in both member and non-member countries of ~~these specialized rigs has improved fleet utilization, which is resulting~~the Organization for Economic Co-operation and Development. Non-member countries are expected to experience the largest population growth and most significant increases in ~~increased dayrates~~living standards, compounding the effect on ~~rigs being tendered for new work~~energy consumption. We believe that this forecasted increase in ~~these regions. Outside of harsh environment markets, and notwithstanding~~global energy demand will support an increase in ~~tendering activity,~~demand for oil and gas. In the ~~excess~~context of the sharp decline in production activities that resulted from the pandemic and the lack of investment in exploration and production activities over the last decade, we believe that this increase in demand will underscore substantial supply constraints that are not easily reversed without significant new investment in drilling and sustained high oil and natural gas prices.

With deepwater and harsh environment fields generating robust economic returns versus other hydrocarbon sources, combined with their comparably low carbon intensity of ~~ultra‑deepwater floaters relative to demand continues to apply downward pressure on dayrates. However, as the hydrocarbon supply‑demand balance improves,~~production, we expect ~~additional upward pressure on oil prices, ultimately resulting~~a significant portion of the required spending in ~~greater demand for ultra‑~~fossil fuel development will be allocated to deepwater and harsh environment projects. As there are now fewer high-specification offshore drilling rigs ~~and improved dayrates for our assets.~~capable of operating in these markets, we believe that this increase in demand will support further improvement of dayrates.

As of October 26, 2017, our contract backlog was $9.4 billion compared to $10.2 billion as of July 25, 2017. The risks of drilling project delays, contract renegotiations and contract terminations and cancellations remain in the near term.

Fleet status—We refer to the availability of our rigs in terms of the uncommitted fleet rate. The uncommitted fleet rate is defined as the number of uncommitted days divided by the total number of rig calendar days in the measurement period, expressed as a percentage. An uncommitted day is defined as a calendar day during which a rig is idle or stacked, is not contracted to a customer and is not committed to a shipyard. The uncommitted fleet rates exclude the effect of priced options. As of ~~October 26, 2017,~~July 25, 2022, the uncommitted fleet rates for the remainder of ~~2017~~2022 and each of the four years in the period ending December 31, ~~2021~~2026 were as follows:

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, ~~and~~ contract preparation, or 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 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.

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. ~~Our contract backlog includes amounts associated with our newbuild units that are currently under construction.~~ It does not include conditional agreements and options to extend firm commitments.

The contractual operating dayrate may be higher than the actual dayrate ~~that~~ we ultimately receive orbecause an alternative contractual dayrate, such as a ~~waiting‑on‑weather~~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 ~~that~~ we ultimately receive because of a number of factors, including rig downtime or suspension of operations.

Our contract backlog for ultra‑deepwater floaters presented as of October 26, 2017, reflects a reduction of approximately $206 million of backlog related to the early termination of this contract. During the year ended December 31, 2016, our customers early terminated or cancelled drilling contracts for ~~Deepwater Asgard~~, ~~Deepwater Champion~~, ~~Deepwater Millennium, Discoverer Deep Seas, Discoverer India, GSF Constellation II, GSF Development Driller I~~ ~~and~~ ~~Transocean John Shaw~~.Contents

On May 31, 2017, we completed the sale of 10 high‑specification jackups and novated the contracts relating to the construction of five high‑specification jackups, together with related assets. At October 26, 2017, the contract backlog for the high‑specification jackups represents the contract backlog associated with the two high‑specification jackups that we continue to operate following the sale.

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 ~~drilling revenues~~terminations, reimbursements and contract intangible amortization, earned per operating day. An operating day is defined as a ~~calendar~~ day ~~during~~for which a rig is contracted to earn a dayrate during the firm contract period after ~~commencement of operations.~~operations commence.

Our revenue efficiency rate varies due to revenues earned under alternative contractual dayrates, such as a ~~waiting‑on‑weather~~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.

Other income and expense—Interest expense, net of amounts capitalized, ~~increased~~decreased in the three months ended ~~September~~June 30, ~~2017,~~2022, compared to the three months ended ~~September~~June 30, ~~2016,~~2021, primarily due to the following: (a) approximately ~~$35~~$9 million resulting from debt repaid as scheduled and (b) approximately $4 million of increased interest ~~expense resulting from debt issued subsequent to September 30, 2016 and (b) approximately $12 million of increased interest expense resulting from reduced interest costs~~ capitalized for our newbuild ~~ultra‑deepwater drillships that commenced operations during the year ended December 31, 2016. Partially offsetting these increases was approximately $45 million of~~projects.

Other income, net, decreased ~~interest expense resulting from the retirement of debt.~~

~~Loss on retirement of debt~~ in the three months ended ~~September~~June 30, 2017, resulted primarily from the retirement of notes validly tendered after the early tender date of the 2017 Tender Offers. Gain on retirement of debt in the three months ended September 30, 2016, resulted primarily from the retirement of notes validly tendered in cash tender offers (the “2016 Tender Offers”).

~~Income tax expense~~—We operate internationally and provide for income taxes based on the tax laws and rates in the countries in which we operate and earn income. In the three months ended September 30, 2017 and 2016, our effective tax rate, excluding discrete items, was 56.5 percent and 26.6 percent, respectively, based on income from continuing operations before income tax expense, after excluding certain items, such as losses on impairment and gains and losses on certain asset disposals. Our effective tax rate increased in the three months ended September 30, 2017,2022, compared to the three months ended ~~September~~June 30, ~~2016,~~2021, primarily due to ~~(a) changes in the relative blend~~reduced income of ~~income from operations in certain jurisdictions and (b) valuation allowances on deferred~~$10 million related to our dual-activity patent.

In the three months ended June 30, 2022 and 2021, the effect of ~~the~~ various discrete period tax items was a net tax ~~expense~~benefit of ~~$90~~less than $1 million and ~~a net tax benefit of $32~~$6 million, respectively. In the three months ended ~~September~~June 30, ~~2017,~~2022, such discrete items ~~were primarily related to tax benefit~~included expiration of ~~changes in unrecognized tax benefit associated with~~various uncertain tax positions ~~taken in prior years~~ and changes to valuation ~~allowances on deferred tax assets not expected to be realized.~~allowances. In the three months ended ~~September~~June 30, ~~2016,~~2021, such discrete items ~~were primarily related to~~included expiration and settlements of various uncertain tax ~~benefit of changes in unrecognized tax benefit associated with tax positions taken in prior years and valuation allowances on deferred tax assets for losses not expected to be realized. For~~positions. In the three months ended ~~September~~June 30, ~~2017~~2022 and ~~2016, these discrete tax items, coupled with the excluded income and expense items noted above, resulted in an~~2021, our effective tax rate, ~~of (14.7)~~excluding discrete items, was (5.2) percent and ~~2.5~~(10.2) percent, respectively, based on ~~income from continuing operations~~loss before income tax ~~expense. Our effective tax rate, after including discrete tax items noted above, excluding the income~~expense or benefit.

Due to our operating activities and expense items noted above, decreased mainly due to loss on impairment and disposal of assets with no tax benefit and valuation allowances recorded on U.S. deferred tax assets not expected to 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. As of September 30, 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 a valuation allowance of $144 million to recognize only a portion of our U.S. deferred tax assets that are more likely than not to be recognized. If estimated future taxable income changes during the carryforward periods or if the cumulative loss is no longer present, we may adjust the amount of deferred tax assets that we expect to realize.

The relationship between our provision for or benefit from income taxes and our income before income taxes can vary significantly from period to period considering, among other factors, (a) the overall level of income before income taxes, (b) changes in the blend of income that is taxed based on gross revenues versus income before taxes, (c) rig movements between taxing jurisdictions and (d) our rig operating structures. Generally, our marginal tax rate is lower than our effective tax rate. Consequently,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 three months ended ~~September~~June 30, ~~2017,~~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, 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.

, Hungary, Norway, Brazil and Switzerland. 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.

Income tax expense—In the six months ended June 30, 2022 and 2021, our effective tax rate was (13.7) percent and 7.7 percent, respectively, based on loss before income tax expense or benefit. In the six months ended June 30, 2022 and 2021, the effect of various discrete period tax items was a net tax benefit of $8 million and $33 million, respectively, and the reduction of such tax benefit was primarily due to reduced releases of uncertain tax positions. In the six months ended June 30, 2022, such discrete items included expiration of various uncertain tax positions and changes to valuation allowances.

In the nine months ended September 30, 2017 and 2016, the effect of the various discrete period tax items was a net tax benefit of $57 million and $24 million, respectively. In the nine months ended September 30, 2017, such discrete items were primarily related to tax benefit of changes in unrecognized tax benefit associated with tax positions taken in prior years, valuation allowances on deferred tax assets for foreign tax credits not expected to be realized, release of a valuation allowance on deferred tax assets for losses expected to be realized and deductions related to resolution of certain litigation matters related to Macondo well incident. In the nine months ended September 30, 2016, such discrete items were primarily related to tax benefit of changes in unrecognized tax benefit associated with tax positions taken in prior years and valuation allowances on deferred tax assets for losses not expected to be realized. For the nine months ended September 30, 2017 and 2016, these discrete tax items, coupled with the excluded income and expense items noted above, resulted in an effective tax rate of (3.6) percent and 17.8 percent, respectively, based on income from continuing operations before income tax expense. Our effective tax rate, after including the discrete tax items noted above, and excluding the income and expense items noted above, decreased mainly due to loss on impairment and disposal of assets with no tax benefit and valuation allowances recorded on U.S. deferred tax assets not expected to be realized.jurisdictions.

For the nine months ended September 30, 2017 and 2016, in accordance with accounting standards for the provision of income taxes, we calculated our annual estimated effective income tax rate of 64.2 percent and 25.9 percent, respectively, by excluding certain operating losses in taxable jurisdictions for which we do not expect to realize a tax benefit. For the nine months ended September 30, 2017 and 2016, if we had included all jurisdictions without regardDue to our ~~expectations for such realization, our estimated effective income tax rate would have been 89.3 percent~~operating activities and ~~22.7 percent, respectively.~~

Sources and uses of liquidity

Overview—We expect to use existing unrestricted cash balances, internally generated cash flows, borrowings under ~~our existing bank credit agreement,~~the Shipyard Loans or the Secured Credit Facility or proceeds from the disposal of assets or ~~proceeds from~~ the issuance of ~~additional~~ debt or shares to fulfill anticipated obligations, which may include ~~business combinations,~~ capital expenditures, working capital and other operational requirements, scheduled debt maturities or other payments. We may ~~also~~ consider establishing additional financing arrangements with banks or other capital ~~providers. Subject~~providers, and subject to market conditions and other factors, we may ~~also~~ be required to provide collateral for any such future financing arrangements. 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 our~~existing unrestricted cash balances, internally generated cash flows and proceeds from asset sales to ~~reduce~~pursue liability management transactions, including among others, purchasing or exchanging one or more existing series of our debt ~~prior to scheduled maturities through debt repurchases, either~~securities in the open market, or in privately negotiated transactions, through tender offers or through ~~debt redemptions~~exchange 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 completed in the years ended December 31, 2021 and 2020. 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.

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.

Our ability and willingness to access tothe debt and equity markets ~~may be limited due to~~is a function of a variety of ~~events,~~factors, including, among others, ~~credit rating agency downgrades of our debt ratings, industry conditions,~~ general economic, ~~conditions,~~industry or market conditions, ~~and~~ market perceptions of us and our ~~industry. In January~~industry and ~~October 2017 and during the year ended December 31, 2016, three~~ credit rating ~~agencies downgraded~~agencies’ views of our ~~non‑credit enhanced senior unsecured long‑term~~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, ~~(“Debt Rating”). Such downgrades have caused and will cause~~which is below investment grade, is causing us to experience increased fees ~~under our credit facility~~ and interest rates under our Secured Credit Facility and agreements governing certain of our senior notes. ~~Further~~Future downgrades may ~~affect or limit~~further restrict our ability to access the debt ~~markets in~~market for sources of capital and may negatively impact the ~~future. Our ability to access~~cost of such ~~markets may be severely restricted~~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. ~~An economic downturn could have an impact~~

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 ~~lenders participating in our credit facilities or on our customers, causing them to fail to meet their obligations to us.~~

~~Our internally generated cash flow is directly related to our business~~secured overnight financing rate (“Term SOFR”) plus the Secured Credit Facility Margin and the market sectors in which we operate. Should the drilling market deteriorate, or should we experience poor results in our operations, cash flow from operations may be reduced. We have, however, continued to generate positive cash flow from operating activities during recent years and expect that such cash flow will continue to be positive during the next year.

~~Business combination—On August 13, 2017, we entered into the Transaction Agreement with Songa pursuant to which we will offer to acquire all~~a Term SOFR spread adjustment of the issued and outstanding shares of Songa. As part of the Offer, we agreed to offer to exchange each of the issued and outstanding shares in Songa for consideration, based on a value of NOK 47.50 per Songa share, consisting of (i) 68.6 million newly issued shares of Transocean Ltd., par value CHF 0.10 per share, and (ii) approximately $575 million aggregate principal amount of 0.5% Senior Unsecured Exchangeable Bonds to be issued by Transocean Inc. (the “Exchangeable Bonds”) exchangeable into shares of Transocean Ltd. Additionally, each Songa shareholder may elect to receive a cash payment of NOK 47.50 per Songa share up to a maximum of NOK 125,000 per shareholder in lieu of some or all of the consideration such shareholder would otherwise be entitled to receive in the Offer.percent. The consideration, as presented in the Offer, is based on an equity value of Songa on a fully diluted basis of approximately NOK 9.1 billion and an enterprise value of approximately NOK 26.4 billion, equivalent to approximately $1.2 billion and $3.4 billion, respectively, measured as of the date of the Offer using a currency exchange ratio of NOK 7.9239 to $1.00. We also expect to (i) acquire certain outstanding bonds issued by Songa in exchange for Exchangeable Bonds, and (ii) acquire a $50 million loan made to Songa by one of its shareholders in exchange for Exchangeable Bonds. The consummation of the OfferSecured Credit Facility is subject to permitted extensions and certain early maturity triggers, including if on any date the ~~satisfaction of customary closing conditions for transactions of this type.~~

~~Debt issuances—On October 17, 2017, we completed an offering of an~~ aggregate ~~principal~~ amount of ~~$750~~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 ~~the 7.50% Senior Notes,~~commitments by up to $250 million. The Secured Credit Facility is guaranteed by Transocean Ltd. and ~~we received aggregate cash proceeds of $742 million, net of issue costs. We intend to use the majority of the net proceeds from the debt offering to repay or redeem~~ certain ~~maturing debt.~~

~~On May 5, 2017, one~~wholly owned subsidiaries. The Secured Credit Facility is secured by, among other things, a lien on nine of our ~~wholly owned subsidiaries completed an offering~~ultra-deepwater floaters and two of ~~an aggregate principal amount of $410 million of the 5.52% Senior~~our harsh environment floaters.

September 29, 2017, our subsidiary made the first of the required quarterly payments of principal and interest. Our subsidiary may redeem all or a portion of the 5.52% Senior Secured Notes at any time on or prior to December 31, 2021 at a price equal to 100 percent of the aggregate principal amount plus, subject to certain exceptions related to the drilling contract for ~~Deepwater Conqueror~~, a make‑whole amount. Our subsidiary will be required to redeem or to offer to redeem the notes at a price equal to 100 percent of the aggregate principal amount, and, under certain circumstances, the paymentCredit Facility contains covenants that, among other things, include maintenance of a ~~make‑whole amount, upon the occurrence of certain events related to~~ ~~Deepwater Conqueror~~ ~~and the related drilling contract.~~

On October 19, 2016 and December 8, 2016, we completed an offering of an aggregate principal amount of $600 million of the 7.75% Senior Secured Notes due October 2024 (the “7.75% Senior Secured Notes”) and $625 million of the 6.25% Senior Secured Notes due December 2024 (the “6.25% Senior Secured Notes”), respectively, and we received aggregate cash proceeds of $583 million and $609 million, respectively, net of initial discount and issue costs. We are required to make semi‑annual payments of interest and principal on these notes. The indentures that govern the 7.75% Senior Secured Notes and the 6.25% Senior Secured Notes contain covenants that limit the ability of our subsidiaries that own or operate the ultra‑deepwater floaters ~~Deepwater Thalassa~~ ~~and~~ ~~Deepwater Proteus~~ to declare or pay dividends and impose a maximum collateral rig leverage ratio (“Maximum Collateral Ratio”), represented by each rig’s earnings relative to the debt balance, which changes over the terms of the notes. At September 30, 2017, the Maximum Collateral Ratio under both indentures was 5.75 to 1.00, and the collateral leverageminimum guarantee coverage ratio of ~~each subsidiary was less than 5.00~~3.0 to ~~1.00.~~

~~On July 21, 2016, we completed an offering~~1.0, a minimum collateral coverage ratio of an aggregate principal amount of $1.25 billion of the 9.00% Senior Notes due July 2023, and we received aggregate cash proceeds of $1.21 billion, net of initial discount and issue costs. We used the majority of the net proceeds from the debt offering2.1 to ~~complete the 2016 Tender Offers.~~

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

On August 1, 2016, we completed the 2016 Tender Offers to purchase for cash up to $1.0 billion aggregate principal amount of certain of our outstanding senior notes (collectively, the “2016 Tendered Notes”). As a result of the 2016 Tender Offers, we received valid tenders from holders of an aggregate principal amount of $981 million of the 2016 Tendered Notes, and in the year ended December 31, 2016, we made an aggregate cash payment of $876 million to settle the 2016 Tendered Notes.

~~Debt repurchases and redemptions~~—In November 2017, we expect to redeem the outstanding 6.00% Senior Notes due March 2018 and the 7.375% Senior Notes due April 2018 with aggregate principal amounts of $319 million and $82 million, respectively, by making an aggregate cash payment of approximately $410 million using proceeds from the issuance of the 7.50% Senior Notes.

In the nine months ended September 30, 2017, we repurchased in the open market an aggregate principal amount of $147 million of our debt securities for an aggregate cash payment of $147 million. In the year ended December 31, 2016, we repurchased in the open market an aggregate principal amount of $399 million of our debt securities for an aggregate cash payment of $354 million.

~~Debt scheduled maturities~~—On the scheduled maturity date of October 16, 2017, we made a cash payment of $152 million to repay the outstanding 2.50% Senior Notes due October 2017, at a price equal to 100 percent of the aggregate principal amount. On the scheduled maturity date of December 15, 2016, we made a cash payment of $938 million to repay the outstanding 5.05% Senior Notes due December 2016, at a price equal to 100 percent of the aggregate principal amount.

~~Revolving credit facility~~—In June 2014, we entered into an amended and restated bank credit agreement, which established a $3.0 billion unsecured five‑year revolving credit facility, which is scheduled to expire on June 28, 2019 (the “Five‑Year Revolving Credit Facility”). Among other things, the Five‑Year Revolving Credit Facility includes limitations on creating liens, incurring subsidiary debt, transactions with affiliates, sale/leaseback transactions, mergers and the sale of substantially all assets. The Five‑Year Revolving Credit Facility also includes a covenant imposing1.0, a maximum debt to ~~tangible~~ capitalization ratio of ~~0.6~~0.60 to ~~1.0. At September 30, 2017,~~1.00 and minimum liquidity of $500 million. The Secured Credit Facility also restricts the ability of Transocean Ltd. and certain of our ~~debt~~subsidiaries to, ~~tangible capitalization ratio, as defined, was 0.36~~among other things, merge, consolidate or otherwise make changes to ~~1.0.~~ the corporate structure, incur liens, incur additional indebtedness, enter into transactions with affiliates and pay dividends and other distributions.

In order to borrow ~~or have letters of credit issued~~ under the ~~Five‑Year Revolving~~Secured Credit Facility, we must, at the time of the borrowing request, not be in default under the ~~bank credit agreements~~Secured Credit Facility and make certain representations and warranties, including with respect to compliance with laws and solvency, to the ~~lenders, but we are not required to make any representation to the lenders as to the absence of a material adverse effect.~~lenders. Repayment of borrowings under the ~~Five‑Year Revolving~~Secured Credit Facility isare subject to acceleration upon the occurrence of an event of default. WeIn order to remain in compliance with the minimum liquidity requirement and to avoid a default under our Secured Credit Facility, we must obtain additional liquidity of at least $330 million within the 12-month period following the issuance of the financial statements included in this report, which we plan to obtain through a secured financing for Deepwater Titan. A failure by us to avoid such a default would eliminate our access to incremental borrowing under the Secured Credit Facility and, since we expect to access borrowings under the Secured Credit Facility, give our lenders the right to declare such borrowings immediately due and payable. Although not assured, we believe it is probable that we will be able to obtain such secured financing for Deepwater Titan in the required timeframe.

Under the agreements governing certain of our debt and finance lease, we are also subject to various covenants, ~~under the indentures pursuant to which our public debt was issued,~~ including restrictions on creating liens, engaging in sale/leaseback transactions and engaging in certain merger, consolidation or reorganization

transactions. A default under our public debt indentures, the agreements governing our ~~capital~~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 ~~Five‑Year Revolving~~Secured Credit Facility and, if not waived by the lenders, could cause us to lose access to the ~~Five‑Year Revolving~~Secured Credit Facility.

We may borrow under the Five‑Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate plus a margin (the “Five‑Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the Debt Rating, or (2) the base rate specified in the credit agreement plus the Five‑Year Revolving Credit Facility Margin, less one percent per annum. Throughout the term of the Five‑Year Revolving Credit Facility, At July 27, 2022, we pay a facility fee on the daily unused amount of the underlying commitment which ranges from 0.15 percent to 0.35 percent based on our Debt Rating. At October 24, 2017, based on our Debt Rating on that date, the Five‑Year Revolving Credit Facility Margin was 2.0 percent and the facility fee was 0.35 percent. At October 24, 2017, we

~~Litigation settlements~~Shipyard financing arrangement—On May 29, 2015, together with the Plaintiff Steering Committee, (the “PSC”) we filed a settlement agreement (the “PSC Settlement Agreement”) in which we agreed to pay a total of $212 million, plus up to $25 million for partial reimbursement of attorneys’ fees, to resolve (1) punitive damages claims of private plaintiffs, businesses, and local governments and (2) certain claims that BP plc. (together with its affiliates, “BP”) had made against us and had assigned to private plaintiffs who previously settled economic damages claims against BP. On February 15, 2017, the U.S. District Court for the Eastern District of Louisiana (the “MDL Court”) entered a final order and judgement approving the PSC Settlement Agreement, which is no longer subject to appeal. In June ~~2016~~2021, we entered into 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 ~~August 2015,~~Deepwater Titan. In June 2022, we borrowed $349 million under the Shipyard Loan and made a cash ~~deposit~~payment of ~~$25~~$46 million to satisfy the final milestone payment due upon delivery of Deepwater Atlas. At July 25, 2022, we had no borrowings outstanding under the Shipyard Loan for Deepwater Titan. We expect to borrow approximately $90 million upon delivery of Deepwater Titan in the six months ending December 31, 2022. In certain circumstances, the maximum aggregate borrowing capacity under the Shipyard Loan for Deepwater Titan may be increased to approximately $440 million, and ~~$212 million, respectively, into an escrow account pending approval~~such Shipyard Loan may also be secured by, among other security, a lien on the rig. 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.

In the six months ended June 30, 2022, we made a ~~wholly owned indirect subsidiary~~cash contribution of $10 million for a noncontrolling equity investment in Ocean Minerals LLC, the parent company of Moana Minerals Ltd. (“Moana”), a Cook Islands subsea resource development company that was recently awarded an exploration license by the Cook Islands Seabed Minerals Authority, granting it exploration rights to a large subsea geographic area with substantial quantities of polymetallic nodules. These nodules contain high concentrations of metals capable of addressing some of the projected supply shortages of metals needed for alternative energy technologies, including for components of electric vehicles. In connection with our investment, we retain a priority right to provide deepwater nodule extraction services to Moana. Along with Moana and others, we intend to extract the nodules in an environmentally responsible way by employing existing and developing new technologies.

Expansion—From time to time, we review possible acquisitions of businesses and drilling rigs, as well as noncontrolling interests in other companies, and we 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~~Any such ~~investment without first obtaining customer contracts. Any~~ acquisition ~~upgrade~~ or ~~new rig construction~~investment 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 subsequently secure drilling contracts ~~for rigs under construction~~in these instances, if not already secured, could have an adverse effect on our results of operations or cash flows.

On August 13, 2017, we entered into the Transaction Agreement with Songa pursuant to which we will offer to acquire all of the issued and outstanding shares of Songa, subject to certain conditions, through the Offer. At October 24, 2017, Songa owned and operated seven mobile offshore drilling units, including four harsh environment floaters and three midwater floaters. See Notes to Condensed Consolidated Financial Statements—Note 4—Business Combination and “—Liquidity and Capital Resources—Sources and uses of liquidity.”

In the nine months ended September 30, 2017, we made capital expenditures of $386 million, including capitalized interest of $91 million. We only capitalize interest costs during periods in which progress for construction projects continues to be underway. As of September 30, 2017, we had ceased capitalization of interest costs on our two uncontracted newbuilds due to a pause in construction. The historical and projected capital expenditures and ~~other~~non-cash capital additions ~~including capitalized interest,~~ for our ongoing ~~major~~newbuild construction projects were as follows:

In June 2022, we borrowed $349 million under the ~~Daewoo Shipbuilding & Marine Engineering Co.

We recorded the Shipyard Loan, net of imputed interest, and corresponding non-cash capital additions of $300 million. Following mobilization, readiness testing and customer acceptance, we expect the rig to commence operations under its drilling contract in ~~Korea,~~the fourth quarter of 2022, in the first of two phases, using a 15,000 pounds per square inch blowout preventer. Before the start of the second phase, the rig will undergo installation of a 20,000 pounds per square inch blowout preventer and related equipment, which is expected to ~~commence operations~~be commissioned in the ~~first quarter of 2018.~~

The ultimate amount of our capital expenditures is partly dependent upon financial market conditions, the actual level of operational and contracting activity, the costs associated with the current regulatory environment and customer requested capital improvements and equipment for which the customer agrees to reimburse us. As with any major shipyard project that takes place over an extended period of time, the actual costs, the timing of expenditures and the project completion date may vary from estimates based on numerous factors, including actual contract terms, weather, exchange rates, shipyard labor conditions, availability of suppliers to recertify equipment and the market demand for components and resources required for drilling unit construction.

~~Contingencies and Uncertainties~~

~~Macondo well incident~~

A significant portion of the contingencies arising from the Macondo well incident has now been resolved as a result of settlements with the Department of Justice (the “DOJ”), BP and the states of Alabama, Florida, Louisiana, Mississippi and Texas. Additionally, we entered into the PSC Settlement Agreement, which has been approved by the MDL Court and is no longer subject to appeal. We believe the remaining most notable claims against us arising from the Macondo well incident are the 30 settlement class opt‑outs from the PSC Settlement Agreement. We can provide no assurance as to the outcome of the remaining claims arising from the Macondo well incident, the timing of any upcoming appeal or further rulings, or that we will not enter into additional settlements as to some or all of the remaining matters related to the Macondo well incident. See Notes to Condensed Consolidated Financial Statements—Note 11—Commitments and Contingencies.Other Matters

Regulatory matters

~~Consent Decree~~—Under the civil consent decree (the “Consent Decree”), we agreed to undertake certain actions, including enhanced safety and compliance actions when operating in U.S. waters. The Consent Decree also requires us to submit certain plans, reports and submissions and also requires us to make such submittals available publicly. One of the required plans is a performance plan approved on January 2, 2014, that contains, among other things, interim milestones for actions in specified areas and schedules for reports required under the Consent Decree. Additionally, in compliance with the requirements of the Consent Decree and upon approval by the DOJ, we retained an independent auditor to review and report to the DOJ our compliance with the Consent Decree and an independent process safety consultant to review, report and assist with the process safety requirements of the Consent Decree. We may request termination of the Consent Decree after January 2, 2019, provided we meet certain conditions. The Consent Decree resolved the claim by the U.S. for civil penalties under the Clean Water Act. We also agreed to pay, and have satisfied our obligations to pay, civil penalties of $1.0 billion plus interest.

For a description of other regulatory and environmental matters relating to the Macondo well incident, please see “—Macondo well incident.” See also Notes to Condensed Consolidated Financial Statements—Note 11—Commitments and Contingencies.

~~Tax matters~~

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

We file federal and local tax returns in several jurisdictions throughout the world. Tax authorities in certain jurisdictions are examining our tax returns and in some cases have issued assessments. We are defending our tax positions in those jurisdictions. While we cannot predict or provide assurance as to the final outcome of these proceedings, we do not expect the ultimate liability to have a material adverse effect on our condensed consolidated statement of financial position or results of operations, although it may have a material adverse effect on our condensed consolidated statement of cash flows.

~~See Notes to Condensed Consolidated Financial Statements—Note 7—Income Taxes.~~

~~Other matters~~

~~In addition, from time to time, 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 Condensed Consolidated Financial Statements—Note 9—Contingencies.

Controls and Procedures

~~Item 4.Controls and Procedures~~

Disclosure controls and procedures—We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as defined in the Exchange Act, Rules 13a‑15 and 15d‑15, as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the United States (the “U.S.”) Securities Exchange Act of 1934 is (1) accumulated and communicated to our management, including our Chief Executive Officer, who is our principal executive officer, and

- 24 -

Table of Contents

our Chief Financial Officer, who is our principal financial officer, to allow timely decisions regarding required disclosure and (2) recorded, processed, summarized and reported within the time periods specified in the ~~United States (“~~U.S.”) Securities and Exchange Commission’s rules and forms. Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, we performed an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that ~~due to the material weakness in internal control over financial reporting as set forth below,~~ our disclosure controls and procedures were ~~not~~ effective as of ~~September~~June 30, ~~2017.~~2022.

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

~~- 34 -~~

~~Table of Contents~~

interim financial statements in 2016 and 2015. The corrections of prior year financial statements for 2014 and 2015 are included in the consolidated financial statements for the year ended December 31, 2016, that are included in our annual report on Form 10‑K, filed on March 7, 2017.

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

Notwithstanding the material weakness described above and after having performed additional procedures, management has concluded that the condensed consolidated financial statements in this quarterly report on Form 10‑Q fairly present, in all material respects, our financial position, results of operations and cash flows for all periods and dates presented.

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

~~Add additional personnel and resources with the appropriate level of tax accounting experience~~

~~Invest in additional technical tax accounting training~~

~~Enhance integration and documentation standards within and between tax and other key departments~~

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

~~Changes in internal control over financial reporting~~—There were no changes to our internal control over financial reporting during the quarter ended ~~September~~June 30, ~~2017,~~2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting, except the changes related to executing our ongoing remediation efforts as noted above. We have not yet reached a conclusion as to the effectiveness of our remediation efforts enacted to date, as the effectiveness of such remediation efforts will be subject to internal controls testing and assessment for our evaluation of internal control over financial reporting as of December 31, 2017.reporting.

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” “we,” “us,” or “our”) has certain actions, claims and other matters pending as discussed and reported in “Part II. Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies” and “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—~~Contingencies and Uncertainties—Macondo well incident”~~Other Matters—Regulatory matters” in our annual report on Form ~~10‑K~~10-K for the year ended December 31, ~~2016.~~2021. We are also involved in various tax matters as described in “Part II. Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—Note 7—11—Income Taxes” and in “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—~~Contingencies and Uncertainties—~~Other Matters—Tax matters” in our annual report on Form ~~10‑K~~10-K for the year ended December 31, ~~2016.~~2021. All such actions, claims, tax and other matters are incorporated herein by reference.

As of ~~September~~June 30, ~~2017,~~2022, we were ~~also~~ involved in a number of other lawsuits, regulatory matters, disputes and claims, asserted and ~~disputes,~~unasserted, all of which have arisen in the ordinary course of our business and for which we do not expect the liability, if any, to have a material adverse effect on our ~~condensed~~ consolidated ~~statement of~~ financial position, results of operations or cash flows. We cannot predict with certainty the outcome or effect of any of the matters referred to above or of any such other pending, threatened or ~~threatened~~possible litigation or legal proceedings. ~~There~~We can beprovide no assurance that our beliefs or expectations as to the outcome or effect of any lawsuit or claim or dispute will prove correct, and the eventual outcome of these matters could materially differ from management’s current estimates.

On December 17, 2021, Transocean Offshore Deepwater Drilling Inc., our wholly owned subsidiary, received a letter from the United States (the “U.S.”) Department of Justice (the “DOJ”) related to alleged violations by our subsidiary of its Clean Water Act (“CWA”) National Pollutant Discharge Elimination System permit (“Permit”). The alleged violations, involving seven of our drillships, were identified by the U.S. Environmental Protection Agency (“EPA”) following an initial inspection in 2018 of our compliance with the Permit and the CWA and relate to deficiencies with respect to records retention, reporting requirements, discharges, permit limits, inspections and maintenance, and the submission of monitoring reports. In connection with the initial EPA inspection, we initiated modifications to our Permit and CWA compliance processes and maintained a dialogue with the EPA regarding the design and implementation of enhancements to these processes. At the DOJ’s invitation, in an effort to resolve the matter, we have initiated settlement discussions with the DOJ, and the enforcement action will likely result in our agreeing to take or continue to take certain corrective actions to ensure current and future Permit and CWA compliance and to pay a monetary penalty, which we believe at this time would be immaterial. We do not believe that the enforcement action would have a material adverse effect on our consolidated financial position, results of operations or cash flow. If our current expectations relating to these costs prove to be inaccurate, future expenditures may exceed our accrued amounts.

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

Item 1A.

Risk Factors

~~Item 1A.Risk Factors~~

~~With exception to the following, there~~There have been no material changes to the risk factors as previously disclosed in ~~“Item~~“Part I. Item 1A. Risk Factors” in our annual report on Form ~~10‑K~~10-K for the year ended December 31, ~~2016.~~

~~The expected benefits associated with a combination with the Songa may not be realized.~~

Following the completion of the voluntary offer (the “Offer”) to acquire Songa Offshore SE and its subsidiaries (collectively, “Songa”), we intend to integrate these companies into the Transocean group. There can be no assurances that we will not encounter difficulties in integrating Songa’s operations or that the benefits expected from the integration will be realized. For example, certain of Songa’s existing indebtedness and agreements include change of control or acceleration provisions that are expected to be triggered in connection with the completion of the Offer, or otherwise permits Songa debt holders to receive Songa shares after the expiration of the Offer. If we are unable to amend or obtain a waiver of these provisions from the relevant counterparties, we may be required to make payments under the terms of the indebtedness or agreements or otherwise be unable to include certain Songa shares in the Offer, which in each case may limit our ability to fully integrate Songa’s business on the timeline we currently anticipate or that may prevent us from fully realizing all of the benefits we currently anticipate from our acquisition of Songa. If the benefits are not achieved, or only partly achieved, this could adversely affect our business or our statement financial condition or results of operations.

~~The Offer is subject to conditions and the Transaction Agreement may be terminated in accordance with its terms and the Combination may not be completed.~~

The Offer is subject to numerous conditions, as defined in the transaction agreement (the “Transaction Agreement”), including the conditions related to the minimum number of Songa shares that must be validly tendered, and not subsequently validly withdrawn as of the end of the offer period, the receipt of regulatory approvals and the absence of material adverse changes with respect to Songa. No assurance can be given that all of the conditions to the Offer will be satisfied or, if they are, as to the timing of such satisfaction. If the Offer has not become or been declared unconditional before 11:59 p.m. (central European time) on January 31, 2018, either party may terminate the Transaction Agreement, unless extended in accordance with the terms of the agreement.

We must obtain governmental and regulatory approvals to consummate the Offer, which, if delayed or not granted, may delay or jeopardize the Offer and the transactions contemplated by the Transaction Agreement.

The approval of the Offer under merger control or competition law regimes in any jurisdictions where the parties to the Transaction Agreement have mutually determined merger control or competition law filings or notices to be necessary must have been

obtained or any statutory waiting period, including any extension thereof, applicable to the Offer must have expired with the result that the Offer may be completed without the approval by any relevant antitrust authority.

The governmental and regulatory agencies from which we may be required to seek these approvals have broad discretion in administering the applicable governing regulations. As a condition to their approval of the transactions contemplated by the Transaction Agreement, those agencies may impose requirements, limitations or costs or require divestitures or place restrictions on the conduct of our business. No assurance can be given that the approvals, if required, will be obtained or that any required conditions to the Offer will be satisfied, and, if any such required approvals are obtained and the conditions to the consummation of the Offer are satisfied, no assurance can be given as to the terms, conditions and timing of the approvals. The Offer is subject to a regulatory condition that certain approvals are obtained. This condition may only be waived with the prior written consent of Songa.

Any delay in the completion of the transaction for regulatory reasons could diminish the anticipated benefits of the combination or result in additional transactions costs. Any uncertainty over the ability to complete the transaction could make it more difficult for us or Songa to maintain or to pursue particular business strategies. Conditions imposed by regulatory agencies in connection with their approval of the transaction may restrict our ability to modify the operations of our business in response to changing circumstances for a period of time after the closing of the Offer or its ability to expend cash for other uses or otherwise have an adverse effect on the anticipated benefits of the transaction, thereby adversely impacting the business, financial condition or results of operations of the combined company.

The announcement and pendency of the Offer and the other transactions contemplated by the Transaction Agreement, during which we and Songa are subject to certain operating restrictions, could have an adverse effect on our and Songa’s businesses and cash flows, financial condition and results of operations

The announcement and pendency of the transactions contemplated by the Transaction Agreement, including the Offer, could disrupt Songa’s and our businesses, and uncertainty about the effect of these transactions may have an adverse effect on Songa and us. These uncertainties could cause suppliers, vendors, partners and others that deal with us and Songa to defer entering into contracts with, or making other decisions concerning, us and Songa or to seek to change or cancel existing business relationships with the companies. In addition, Songa and our employees may experience uncertainty regarding their roles after the acquisition. Employees may depart either before or after the completion of the acquisition because of uncertainty and issues relating to the difficulty of coordination or because of a desire not to remain following the acquisition. Therefore, the pendency of the Offer may adversely affect Songa’s and our ability to retain, recruit and motivate key personnel. In addition, the attention of Songa’s and our management may be directed towards the completion of the acquisition, including obtaining regulatory approvals, and may be diverted from the day‑to‑day business operations of us and Songa. Matters related to the acquisition may require commitments of time and resources that could otherwise have been devoted to other opportunities that might have been beneficial to us and Songa. In addition, the Transaction Agreement requires that we and Songa refrain from taking certain specified actions while the Offer and the acquisition are pending. These restrictions may prevent us and Songa from pursuing otherwise attractive business opportunities or capital structure alternatives and from executing certain business strategies prior to the completion of the Offer. Further, the acquisition may give rise to potential liabilities, including those that may result from future shareholder lawsuits. Any of these matters could adversely affect the businesses of, or harm the results of operations, financial condition or cash flows of, us and Songa.

~~Negative publicity related to the transactions contemplated by the Transaction Agreement may materially adversely affect us and Songa~~

From time to time, political and public sentiment in connection with a proposed combination may result in a significant amount of adverse press coverage and other adverse public statements affecting us and Songa. Adverse press coverage and public statements, whether or not driven by political or popular sentiment, may also result in legal claims or in investigations by regulators, legislators and law enforcement officials. Responding to these investigations and lawsuits, regardless of the ultimate outcome of the proceedings, can divert the time and effort of senior management from operating their businesses. Addressing any adverse publicity, governmental scrutiny or enforcement or other legal proceedings is time‑consuming and expensive and, regardless of the factual basis for the assertions being made, could have a negative impact on our reputation and that of Songa, on the morale of our or their employees and on our or their relationships with regulators. It may also have a negative impact on their ability to take timely advantage of various business and market opportunities. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on Songa’s and our respective business and cash flows, financial condition and results of operations.

~~Our share price may be adversely affected if the Offer is not completed~~

If the Offer is not completed, then our share price may decline to the extent that the current market price of our shares reflect a market premium based on the assumption that the Offer will be completed.
