Business | Overview—Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells. We specialize in technically demanding sectors of the offshore drilling business with a particular focus on ultra‑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 March 31, 2018, we owned or had partial ownership interests in and operated 47 mobile offshore drilling units, including 27 ultra‑deepwater floaters, 12 harsh environment floaters, two deepwater floaters and six midwater floaters. Additionally, at March 31, 2018, 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 March 31, 2018, we are constructing two additional ultra‑deepwater drillships. See Note 7—Drilling Fleet. Business combination—On January 30, 2018, we acquired an approximate 97.7 percent ownership interest in Songa Offshore SE, a European public company limited by shares, or societas Europaea, existing under the laws of Cyprus (“Songa”). On March 28, 2018, we acquired the remaining shares not owned by us through a compulsory acquisition under Cyprus law, and as a result, Songa became our wholly owned subsidiary. In connection with these transactions, we issued an aggregate of 68.0 million shares and $863 million aggregate principal amount of 0.50% exchangeable senior bonds due January 30, 2023 (the “Exchangeable Bonds”). As a result of the acquisition, we acquired seven mobile offshore drilling units, including five harsh environment floaters and two midwater floaters. See Note 4—Business Combination. |

Significant Accounting Policies | |
Significant Accounting Policies | 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 and Article 10 of Regulation S‑X of the U.S. Securities and Exchange Commission (“SEC”). 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 months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018, 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, 2017 and 2016 and for each of the three years in the period ended December 31, 2017, included in our annual report on Form 10‑K filed on February 21, 2018. Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted in the U.S., we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and assumptions, including those related to our allowance for doubtful accounts, materials and supplies obsolescence, property and equipment, assets held for sale, goodwill, income taxes, contingencies, share‑based compensation and postemployment benefit plans. We base our estimates and assumptions on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ from such estimates. Fair value measurements—We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market for the asset or liability. Our valuation techniques require inputs that we categorize using a three‑level hierarchy, from highest to lowest level of observable inputs, as follows: (1) significant observable inputs, including unadjusted quoted prices for identical assets or liabilities in active markets (“Level 1”), (2) significant other observable inputs, including direct or indirect market data for similar assets or liabilities in active markets or identical assets or liabilities in less active markets (“Level 2”) and (3) significant unobservable inputs, including those that require considerable judgment for which there is little or no market data (“Level 3”). When multiple input levels are required for a valuation, we categorize the entire fair value measurement according to the lowest level of input that is significant to the measurement even though we may have also utilized significant inputs that are more readily observable. Business combination—In connection with our acquisition of Songa, we applied the acquisition method of accounting. Accordingly, we recorded the acquired assets and assumed liabilities at fair value and recognized goodwill to the extent the consideration transferred exceeded the fair value of the net assets acquired. We estimated the fair values of the acquired assets and assumed liabilities as of the date of the acquisition, and our estimates are subject to adjustment based on our final assessments of the fair values of property and equipment, intangible assets, liabilities and our evaluation of tax positions and contingencies, which are ongoing. We will complete our final assessments of the fair values of the acquired assets and assumed liabilities and our final evaluations of uncertain tax positions and contingencies within one year of the acquisition date. See Note 4—Business Combination. Goodwill—We conduct impairment testing for our goodwill annually as of October 1 and more frequently, on an interim basis, when an event occurs or circumstances change that indicate that the fair value of a reporting unit may have declined below its carrying value. We test goodwill at the reporting unit level, which is defined as an operating segment or one level below an operating segment that constitutes a business for which financial information is available and is regularly reviewed by management. We determined that we have a single reporting unit for this purpose. Before testing goodwill, we consider whether or not to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, as the result of our qualitative assessment, we determine that an impairment test is required, or, alternatively, if we elect to forgo the qualitative assessment, we record an impairment to goodwill to the extent the carrying amount of the reporting unit, including goodwill, exceeds the fair value of the reporting unit. At March 31, 2018, the carrying amount of our goodwill was $460 million. See Note 3—Accounting Standards Updates and Note 4—Business Combination. Contract intangible assets—In connection with our acquisition of Songa, we recognized drilling contract intangible assets related to the acquired drilling contracts for future contract drilling services. The drilling contract intangible assets represent the amount by which the fixed dayrates of the acquired contracts were above the market dayrates that were available or expected to be available during the term of the contract for similar contracts, measured as of the acquisition date. We recognize the amortization on a straight‑line basis over the firm contract period as a component of contract drilling revenues. At March 31, 2018, the carrying amount of our drilling contract intangible assets was $613 million. See Note 4—Business Combination. Derivative instruments—We record derivatives on our consolidated balance sheet, measured at fair value. We recognize the gains and losses associated with changes in the fair value in current period earnings. See Note 10—Derivative Instruments. Capitalized interest—We capitalize interest costs for qualifying construction and upgrade projects and only capitalize interest costs during periods in which progress for the construction projects continues to be underway. As of March 31, 2018, we had ceased capitalization of interest costs on one of our two uncontracted newbuild drillships due to a pause in construction in progress. In the three months ended March 31, 2018 and 2017, we capitalized interest costs of $13 million and $30 million, respectively, for our construction work in progress. Reclassifications—We have made certain reclassifications to prior period amounts to conform with the current period’s presentation. In our condensed consolidated balance sheet as of December 31, 2017, we reclassified certain balances receivable from non‑customers, totaling $45 million, from accounts receivable, net, to other current assets. Such reclassifications did not have a material effect on our condensed consolidated statement of financial position, results of operations or cash flows. |

Accounting Standards Updates |
3 Months Ended |

Accounting Standards Updates | |
Accounting Standards Updates | Note 3—Accounting Standards Updates Recently adopted accounting standards Revenue from contracts with customers—Effective January 1, 2018, we adopted the accounting standards update that requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In our evaluation of the requirements, we determined that reimbursement revenues and contract early cancellation and termination fees were part of our single performance obligation, and we determined that reimbursement revenues should be recorded on a gross basis as the service is performed. Our adoption, using the modified retrospective approach, for which we were not required to make any changes to the prior year presentation, did not have a material effect on our condensed consolidated statements of financial position, operations and cash flows. See Note 6—Revenues. Income taxes—Effective January 1, 2018, we adopted the accounting standards update that requires an entity to recognize the income tax consequences of an intra entity transfer of an asset other than inventory when the transaction occurs as opposed to deferring such recognition into future periods. Our adoption did not have a material effect on our condensed consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes to condensed consolidated financial statements. Statement of cash flows—Effective January 1, 2018, we adopted the accounting standards update that requires amounts generally described as restricted cash or restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning and end of period total amounts presented on the statement of cash flows. Aside from presenting the restricted cash and restricted cash equivalents as a component of the beginning and ending cash balances on our condensed consolidated statements of cash flows, we removed the effect of proceeds from and deposits to restricted accounts from our cash flows provided by or used in operating and financing activities, as applicable. For the three months ended March 31, 2018 and 2017, such changes did not have a material effect on our condensed consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes to condensed consolidated financial statements. Retirement benefits—Effective January 1, 2018, we adopted the accounting standards update that requires an employer to disaggregate the service cost component from the other components of net benefit cost related to defined benefit retirement plans and other postemployment benefit plans. The update requires that the service cost component be presented in the same line item as other compensation costs for employees and the other components of net benefit cost in other income and expense on our condensed consolidated statements of operations. The update also allows only the service cost component of net benefit cost to be eligible for capitalization. Our adoption did not have a material effect on our condensed consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes to condensed consolidated financial statements. Goodwill—Effective January 1, 2018, we early adopted the accounting standards update that simplifies the method for measuring the implied value of goodwill when performing a goodwill impairment test by performing a one‑step test, comparing the fair value of the reporting unit with its carrying amount. The update eliminates the two‑step requirement to perform procedures to determine the fair value of assets and liabilities on the same basis as required in a business combination. The update, which permits early adoption, is effective for interim and annual periods beginning after December 15, 2019, including interim periods within those annual periods. Our adoption did not have an effect on our condensed consolidated statements of financial position, operations and cash flows and on the disclosures contained in our notes to condensed consolidated financial statements. Recently issued accounting standards Leases—Effective no later than January 1, 2019, we will adopt the accounting standards update that (a) requires lessees to recognize a right to use asset and a lease liability for virtually all leases, and (b) updates previous accounting standards for lessors to align certain requirements with the updates to lessee accounting standards and the revenue recognition accounting standards. The update, which permits early adoption, is effective for interim and annual periods beginning after December 15, 2018, including interim periods within those annual periods. Under the updated definition of a lease, we have determined that our drilling contracts could contain a lease component. In a recent update, targeted improvements were proposed to the accounting standards that provide for (a) an optional new transition method for adoption that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption and (b) a practical expedient for lessors, under certain circumstances, to combine the lease and non‑lease components of revenues for presentation purposes. Our adoption, and the ultimate effect on our consolidated financial statements, will be based on an evaluation of the contract‑specific facts and circumstances. Additionally, based on the lease arrangements under which we are the lessee as of March 31, 2018, we expect to recognize an aggregate lease liability and a corresponding right‑to‑use asset of between $75 million and $85 million. We do not expect our adoption to have a material effect on our condensed consolidated statements of financial position, operations and cash flows. We continue to evaluate the requirements with regard to arrangements under which we are the lessor, the proposed targeted updates and the effects such requirements may have on the disclosures contained in our notes to condensed consolidated financial statements. Other comprehensive income—Effective no later than January 1, 2019, we will adopt the accounting standards update that allows for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). The update, which permits early adoption is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods. We continue to evaluate the requirements and do not expect our adoption to have a material effect on our condensed consolidated statements of financial position, operations and cash flows and on the disclosures contained in our notes to condensed consolidated financial statements. |

Business Combination | Note 4—Business Combination Overview—On August 13, 2017, we entered into a transaction agreement with Songa pursuant to which we agreed to offer to acquire all of the issued and outstanding shares of Songa subject to certain conditions, through a voluntary exchange offer (the “Offer”) in exchange for consideration per Songa share consisting of (i) 0.3572 newly issued shares of Transocean Ltd. and (ii) approximately $2.99726 principal amount of Exchangeable Bonds to be issued by Transocean Inc., our wholly owned direct subsidiary and a Cayman Islands exempted company. Additionally, each Songa shareholder could 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. In connection with the acquisition, shareholders at our extraordinary general meeting, on January 16, 2018, approved: (1) the issuance of up to 68.6 million Transocean Ltd. shares, (2) an amendment of our articles of association to create additional authorized share capital, (3) the election of a new director to our board of directors and (4) the issuance of consideration shares from our authorized share capital and shares issuable upon exchange of the Exchangeable Bonds. We believe the acquisition of Songa strengthens our position as a leader in harsh environment and ultra‑deepwater drilling services by adding high value assets, including four high‑specification harsh environment floaters, supported by significant contract backlog. Additionally, the acquisition strengthens our footprint in harsh environment operating areas. We believe the goodwill resulting from the business combination can be attributed to synergies expected to be realized and intangible assets that do not qualify for separate recognition. In the three months ended March 31, 2018, we incurred acquisition costs of $7 million, recorded in general and administrative costs and expenses. Consideration—On January 30, 2018, we acquired an approximate 97.7 percent ownership interest in Songa. In connection with the acquisition, we issued 66.9 million shares with a market value of $10.99 per share, based on the market value of our shares on the acquisition date. We also issued $854 million aggregate principal amount of Exchangeable Bonds, including $562 million aggregate principal amount as partial consideration to Songa shareholders and $292 million aggregate principal amount as settlement for certain Songa indebtedness. The aggregate fair value of the consideration transferred in the business combination was as follows (in millions):
Assets and liabilities—As of January 30, 2018, we estimated the fair value of assets acquired, liabilities assumed and noncontrolling interest as follows (in millions):
We estimated the fair value of the rigs and related equipment by applying a combination of income and market approaches, using projected discounted cash flows and estimates of the exchange price that would be received for the assets in the principal or most advantageous markets for the assets in an orderly transaction between participants as of the acquisition date. Additionally, we estimated the fair value of the drilling contracts by comparing the contractual dayrates over the remaining firm contract term and option periods relative to the projected market dayrates as of the acquisition date. Our estimates of fair value for these assets required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of our contract drilling services reporting unit, such as future commodity prices, projected demand for our services, rig availability and dayrates. We estimated the fair value of the debt using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. We have not completed our estimates of the fair values of assets acquired and liabilities assumed. We continue to review the estimated fair values of property and equipment, intangible assets, and other assets and liabilities, and to evaluate the assumed tax positions and contingencies. Estimating fair value for such assets and liabilities requires significant assumptions and judgment, which increases the likelihood that the estimates may require adjustment, and such adjustments could be material. Noncontrolling interest—On March 28, 2018, we acquired the remaining Songa shares not owned by us through a compulsory acquisition under Cyprus law, and as a result, Songa became our wholly owned subsidiary. As consideration for the remaining Songa shares, we issued 1.1 million shares and $9 million aggregate principal amount of Exchangeable Bonds and we made an aggregate cash payment of $8 million to Songa shareholders that elected to receive a cash payment or failed to make an election, for an aggregate fair value of $30 million. Contract intangible assets—In the three months ended March 31, 2018, we recognized contract intangible amortization of $19 million, recorded as a reduction of contract drilling revenues. At March 31, 2018, the aggregate carrying amount of contract intangible assets was $613 million, which we expect to amortize over the remaining contract periods, through March 2024. As of March 31, 2018, the estimated future amortization of contract intangible assets was as follows (in millions):
Pro forma combined operating results—We have included the operating results of Songa in our condensed consolidated results of operations, commencing on the acquisition date, January 30, 2018. In the three months ended March 31, 2018, our condensed consolidated statement of operations includes revenues and net loss of $84 million and $3 million, respectively, associated with the operations of Songa. Pro forma combined operating results, assuming the acquisition was completed as of January 1, 2017, were as follows (in millions, except per share data):
The pro forma financial information includes various adjustments, primarily related to additional depreciation resulting from the fair value adjustments to the acquired property and equipment and amortization resulting from the contract intangible assets. The pro forma information is not necessarily indicative of the results of operations had the acquisition of Songa been completed on the assumed dates or the results of operations for any future periods. |

Revenues | Note 6—Revenues Overview—The services we perform represent a single performance obligation under our drilling contracts with customers that is satisfied over time. We earn revenues primarily by performing the following activities: (i) providing our drilling rig, work crews, related equipment and services necessary to operate the rig (ii) delivering the drilling rig by mobilizing to and demobilizing from the drill location, and (iii) performing certain pre‑operating activities, including rig preparation activities or equipment modifications required for the contract. We recognize revenues earned under our drilling contracts based on variable dayrates, which range from a full operating dayrate to lower rates or zero rates for periods when drilling operations are interrupted or restricted, based on the specific activities we perform during the contract on an hourly, or more frequent, basis. Such dayrate consideration is attributed to the distinct time period to which it relates within the contract term, and therefore, recognized as we perform the services. We recognize reimbursement revenues and the corresponding costs as we provide the customer‑requested goods and services, when such reimbursable costs are incurred while performing drilling operations. Prior to performing drilling operations, we may receive pre‑operating revenues, on either a fixed lump‑sum or variable dayrate basis, for mobilization, contract preparation, customer‑requested goods and services or capital upgrades, which we recognize on a straight‑line basis over the estimated firm contract period. We recognize losses for loss contracts as such losses are incurred. We recognize revenues for demobilization or from contract terminations as we fulfill our obligations and all contingencies have been resolved. The duration of our performance obligation varies by contract. At March 31, 2018, the expected remaining duration of our drilling contracts extends through February 2028, excluding unexercised options. In the three months ended March 31, 2018, we recognized revenues of $48 million from performance obligations satisfied in previous periods, primarily related to our customer’s termination of the contract for Discoverer Clear Leader, effective November 2017, and certain revenues recognized on a cash basis. We have taken the optional exemption that permits us to exclude disclosure of the estimated transaction price related to the variable portion of unsatisfied performance obligations at the end of the reporting period, as our transaction price is based on a single performance obligation consisting of a series of distinct hourly, or more frequent, periods, the variability of which will be resolved at the time of the future services. To obtain contracts with our customers, we incur costs to prepare a rig for contract and deliver, or mobilize a rig to the drilling location. We defer pre‑operating costs, such as contract preparation and mobilization costs, and recognize such costs on a straight‑line basis, consistent with the general pace of activity, in operating and maintenance costs over the estimated firm period of drilling. In the three months ended March 31, 2018 and 2017, we recognized costs of $12 million and $13 million, respectively, associated with pre‑operating costs for contracts with customers. At March 31, 2018 and December 31, 2017, the unrecognized pre‑operating costs to obtain contracts was $22 million and $18 million, respectively, recorded in other assets. Revenue disaggregation—In the three months ended March 31, 2018 and 2017, we recognized revenues as follows (in millions):
Contract liabilities—We recognize contract liabilities, recorded in other current liabilities and other long-term liabilities, for mobilization, contract preparation and capital upgrades using the straight‑line method over the remaining contract term. Contract liabilities for our contracts with customers were as follows (in millions):

Income Taxes | |
Income Taxes | Note 8—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 three months ended March 31, 2018 and 2017, our estimated effective tax rate, excluding discrete items, was (42.8) percent and 82.1 percent, respectively, based on estimated annual income or loss before income taxes. In the three months ended March 31, 2018, compared to the three months ended March 31, 2017, our effective tax rate decreased primarily due to changes in the relative blend of income from operations in certain jurisdictions partially offset by the U.S. base erosion and anti‑abuse tax. 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 three months ended March 31, 2018 and 2017, the effect of the various discrete period tax items was a net tax benefit of $1 million and $77 million, respectively. In the three months ended March 31, 2018, such discrete items were primarily related to the tax benefit of changes in unrecognized tax benefit associated with tax positions taken in prior years and remeasurement of the deferred tax assets for a tax rate change. In the three months ended March 31, 2017, such discrete items were primarily related to the 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 three months ended March 31, 2018 and 2017, these discrete tax items, coupled with the excluded income and expense items noted above, resulted in an effective tax rate of (42.2) percent and (73.0) percent, respectively, based on income or loss before income tax expense. U.S. tax reform—In December 2017, the U.S. enacted the 2017 Tax Act, which included prospective changes beginning in 2018, including a base erosion and anti‑abuse tax (“BEAT”), a global intangible low‑taxed income (“GILTI”) tax, additional limitations on the deductibility of executive compensation, limitations on the deductibility of interest and repeal of the domestic manufacturing deduction. Effective January 1, 2018, we elected to treat any potential GILTI inclusions as a period cost. We have evaluated our bare boat charter structure and believe that our U.S. operations are subject to BEAT and have reflected the estimated impact of this tax in our provision for the three months ended March 31, 2018. Transition tax on foreign earnings—Upon enactment of the 2017 Tax Act, we did not have the necessary information available, prepared and analyzed to develop a reasonable estimate of the transition tax. We have not yet completed our calculation of the post‑1986 earnings and profits for the foreign subsidiaries of our U.S. subsidiaries or determined the amounts of those earnings held in cash and other assets necessary to determine the transition tax. The determination of the transition tax requires further analysis regarding the amount and composition of our historical foreign earnings, which is expected to be completed and reflected in our financial statements issued for subsequent reporting periods that fall within the measurement period provided by Staff Accounting Bulletin No. 118. The transition tax will also impact the utilization of our foreign tax credits and net operating losses generated in the U.S. which will impact our valuation allowance analysis related to those deferred tax assets and could have a material impact to our valuation allowances. Because we have not completed our analysis of the amount and composition of our historical foreign earnings and the associated transition tax, we also cannot determine the associated impact on our assertion that the unremitted earnings of the foreign subsidiaries of our U.S. subsidiaries will be indefinitely reinvested. Tax returns—We file federal and local tax returns in several jurisdictions throughout the world. With few exceptions, we are no longer subject to examinations of our U.S. and non‑U.S. tax matters for years prior to 2010. Our tax returns in the major jurisdictions in which we operate, other than Brazil, as mentioned below, are generally subject to examination for periods ranging from three to six years. We have agreed to extensions beyond the statute of limitations in two major jurisdictions for up to 20 years. Tax authorities in certain jurisdictions are examining our tax returns and in some cases have issued assessments. We are defending our tax positions in those jurisdictions. While we cannot predict or provide assurance as to the timing or the outcome of these proceedings, we do not expect the ultimate liability to have a material adverse effect on our 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. Brazil tax investigations—In December 2005, the Brazilian tax authorities issued a tax assessment with respect to our tax returns for the years 2000 through 2004, which is currently for an aggregate amount of BRL 857 million, equivalent to approximately $259 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. On May 19, 2014, the Brazilian tax authorities issued a 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 145 million, equivalent to approximately $44 million, including penalties and interest. On June 18, 2014, we filed a protest letter with the Brazilian tax authorities for this tax assessment. 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. |

Debt | Note 9—Debt Overview Outstanding debt—The aggregate principal amounts and aggregate carrying amounts, net of debt‑related balances, including unamortized discounts, premiums, issue costs and fair value adjustments of our debt, were as follows (in millions):
Scheduled maturities—At March 31, 2018, the scheduled maturities of our debt were as follows (in millions):
Interest rate adjustments—The interest rates for certain of our notes are subject to adjustment from time to time upon a change to the credit rating of our non‑credit enhanced senior unsecured long‑term debt (“Debt Rating”). As of March 31, 2018, the interest rate in effect for the 6.375% senior notes due December 2021, 3.80% senior notes due October 2022 and the 7.35% senior notes due December 2041 was 8.375 percent, 5.80 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 consolidated indebtedness to total 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 (“LIBOR”) plus a margin (the “Five‑Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the Debt Rating, or (2) the base rate specified in the credit agreement plus the Five‑Year Revolving Credit Facility Margin, less one percent per annum. Throughout the term of the Five‑Year Revolving Credit Facility, we pay a facility fee on the daily unused amount of the underlying commitment which ranges from 0.15 percent to 0.35 percent based on our Debt Rating. At March 31, 2018, 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 March 31, 2018, we had no borrowings outstanding, $7 million of letters of credit issued, and we had $3.0 billion of available borrowing capacity under the Five‑Year Revolving Credit Facility. See Note 13—Commitments and Contingencies—Global Marine litigation. Debt issuance Exchangeable bonds—In connection with the Songa acquisition transactions, we issued $863 million aggregate principal amount of Exchangeable Bonds, as partial consideration for the Songa shares and as consideration for refinancing certain Songa indebtedness. Transocean Inc., our wholly owned direct subsidiary, is the issuer of the Exchangeable Bonds, for which Transocean Ltd. has provided a full and unconditional guarantee. We are required to pay interest on the Exchangeable Bonds semiannually on January 30 and July 30 of each year, beginning on July 30, 2018. The Exchangeable Bonds may be converted at any time prior to the maturity date at an exchange rate of 97.29756 shares per $1,000 note equivalent to a conversion price of $10.28 per share, subject to adjustment upon the occurrence of certain events. Holders of Exchangeable Bonds may require us to repurchase all or a portion of such holder’s Exchangeable Bonds upon the occurrence of certain events. The Exchangeable Bonds had an aggregate fair value of $1.04 billion, measured as of the issuance date, and we recorded the value above par, representing a substantial premium of $172 million, to additional paid‑in capital. We estimated the fair value using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. Debt assumption Senior Secured Term Loan Facilities—In connection with the Songa acquisition, we assumed rights and obligations under credit agreements establishing the senior secured term loan facility due August 2025 (the “Senior Secured Term Loan due August 2025”) and the senior secured term loan facility due March 2026 (the “Senior Secured Term Loan due March 2026” and, together, the “Senior Secured Term Loans”). Borrowings under the Senior Secured Term Loan due August 2025 and the Senior Secured Term Loan due March 2026 bear interest at LIBOR plus 3.00 percent and LIBOR plus 2.50 percent, respectively. The Senior Secured Term Loans require scheduled quarterly installments of interest and principal. The credit agreements for the Senior Secured Term Loans limit the ability of our subsidiaries that own or operate the collateral rigs to declare or pay dividends to their affiliates, limit our ability to incur certain liens on our drilling units without equally and ratably securing the notes, to engage in certain sale and lease back transactions covering any of our drilling units, to allow our subsidiaries to incur certain additional debt, or to engage in certain merger, consolidation or reorganization transactions or to enter into a scheme of arrangement qualifying as an amalgamation. Additionally, the credit agreements contain covenants that require us to maintain the following: (a) minimum amounts of liquidity, working capital and equity, (b) a maximum leverage ratio and (c) minimum ratios of equity, interest coverage and asset value-to-loan coverage. The borrowings under the Senior Secured Term Loans are secured by the assets and earnings associated with the harsh environment floaters Songa Equinox, Songa Endurance, Songa Encourage and Songa Enabler. At March 31, 2018, the weighted average interest rate for borrowings under the Senior Secured Term Loan due August 2025 and the Senior Secured Term Loan due March 2026 was 4.77 percent and 3.83 percent, respectively. The credit agreements also contain change of control clauses, for which we received waivers from the lenders, which expire on August 31, 2018. Accordingly, we have classified the borrowings under the Senior Secured Term Loans as debt due within one year. We are evaluating alternatives for refinancing, restructuring or retiring the Senior Secured Term Loans. Junior Secured Bonds—In connection with the Songa acquisition, we assumed the rights and obligations under a subscription agreement establishing a junior secured bond facility, which is scheduled to expire in August 2025 (the “Junior Secured Bonds”). Borrowings under the Junior Secured Bonds bear interest at 7.50 percent. The Junior Secured Bonds require scheduled quarterly installments of interest and principal. The subscription agreement for the Junior Secured Bonds contains covenants consistent with those under the credit agreements for the Senior Secured Term Loans. The borrowings under the Junior Secured Bonds are secured by the assets and earnings associated with the harsh environment floaters Songa Equinox and Songa Endurance, and such borrowings are subordinate to the borrowings under the Senior Secured Term Loans. The subscription agreement also contains change of control clauses, for which we received waivers from the lenders, which expire on August 31, 2018. On February 12, 2018, we served notice of our intent to call the Junior Secured Bonds, effective August 12, 2018. Accordingly, we have classified the borrowings under the Junior Secured Bonds as debt due within one year. Other debt—In connection with the Songa acquisition, we assumed the indebtedness related to two bond loans (together, the “Bond Loans”), previously publicly traded on the Oslo stock exchange. On the acquisition date, the Bond Loans had an aggregate principal amount of NOK 337 million, equivalent to $44 million. On March 14, 2018, we made a cash payment of NOK 345 million, equivalent to $44 million, to repay the Bond Loans. We also assumed the rights and obligations under a credit agreement, expiring March 31, 2018, for a secured borrowing facility. On February 2, 2018, we made a cash payment of $23 million to repay the borrowings outstanding under the secured borrowing facility. Debt retirements During the three months ended March 31, 2017, we repurchased in the open market an aggregate principal amount of $15 million of our debt securities for an aggregate cash payment of $15 million. As a result of the repurchases, we retired the respective aggregate principal amounts of our debt securities as follows: $3 million of the 6.50% Senior Notes due November 2020, $6 million of the 6.375% Senior Notes due 2021, and $6 million of the 3.80% Senior Notes due 2022. |

Derivatives instruments | Note 10—Derivative Instruments Interest rate swaps—In connection with the Songa acquisition, we acquired interest rate swaps, which were previously designated but no longer qualify as a cash flow hedge, to reduce the variability of cash interest payments associated with the variable rate borrowings under the Senior Secured Term Loan Facilities, which are expected to be refinanced, restructured or retired by August 31, 2018. On the acquisition date, the aggregate fair value of the undesignated interest rate swaps represented an asset of $14 million. In the three months ended March 31, 2018, we recognized a gain of $3 million, recorded in other, net, associated with the fair value adjustments to the undesignated interest rate swaps. At March 31, 2018, the aggregate fair value of the undesignated interest rate swaps was $17 million, recorded in other current assets. At March 31, 2018, the aggregate notional amounts and weighted average interest rates for our undesignated interest rate swaps were as follows (in millions, except weighted average interest rates):
Forward exchange contracts—In connection with the Songa acquisition, we acquired certain undesignated forward exchange contracts, extending through May 2018, which represent an economic hedge to reduce the variability of cash payments of expenditures denominated in Norwegian krone. On the acquisition date, the aggregate fair value of the forward exchange contracts represented an asset of $4 million. In the three months ended March 31, 2018, we recognized a loss of $3 million, recorded in other, net, associated with the fair value adjustments resulting from currency exchange rates.

Currency swaps—Additionally, in connection with our Songa acquisition, we acquired currency swaps, which were previously designated as a cash flow hedge, to reduce the variability of cash interest payments and the final cash principal payment associated with the Bond Loans resulting from the changes in the U.S. dollar to Norwegian krone exchange rate. On the acquisition date, the aggregate fair value of the currency swaps represented a liability of $81 million. In the three months ended March 31, 2018, we settled and terminated the currency swaps for an aggregate cash payment of $92 million, and we recognized a loss of $11 million, recorded in other, net. |

Commitments and Contingencies | Note 13—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 District of Louisiana (the “MDL Court”). A significant portion of the contingencies arising from the Macondo well incident has now been resolved or is pending release of funds from escrow (see “—PSC Settlement Agreement”). As for any actions not resolved by our previous settlements, including any claims by individuals who opted out of the settlement agreement that we and the Plaintiff Steering Committee (the “PSC”) filed with the MDL Court in May 2015 (the “PSC Settlement Agreement”), we will vigorously defend those claims and pursue any and all defenses available. We have recognized a liability for the remaining estimated loss contingencies associated with litigation resulting from the Macondo well incident that we believe are probable and for which a reasonable estimate can be made. At March 31, 2018 and December 31, 2017, the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $219 million, recorded in other current liabilities, the majority of which is related to our settlement with the PSC. Plea Agreement—Pursuant to the plea agreement (the “Plea Agreement”), one of our subsidiaries pled guilty to one misdemeanor count of negligently discharging oil into the U.S. Gulf of Mexico, in violation of the Clean Water Act, for which our subsidiary is no longer subject to probation. We also agreed to make an aggregate cash payment of $400 million, including a criminal fine and certain cash contributions payable in scheduled installments. In the three months ended March 31, 2017, we made a cash payment of $60 million, representing the final installment 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) 72.8 percent to private plaintiffs, businesses, and local governments who could have asserted punitive damages claims against us under general maritime law ; and (2) 27.2 percent to private plaintiffs who previously settled economic damages claims against BP and were assigned certain claims BP had made against us. In exchange for these payments, each of the classes agreed to release all respective claims it has against us. Thirty claimants elected to opt out of the PSC Settlement Agreement. In June 2016 and August 2015, we made a cash deposit of $25 million and $212 million, respectively, into escrow accounts established by the MDL Court for the settlement. On February 15, 2017, the MDL Court entered a final order and judgement approving the PSC Settlement Agreement, which is no longer subject to appeal. In November 2017, the MDL Court released $25 million from the escrow accounts for payment of attorneys’ fees. At March 31, 2018 and December 31, 2017, the aggregate cash balance in escrow accounts was $213 million and $212 million, respectively, recorded in restricted cash accounts and investments. Other legal proceedings Asbestos litigation—In 2004, several of our subsidiaries were named, along with numerous other unaffiliated defendants, in complaints filed in the Circuit Courts of the State of Mississippi, and in 2014, a group of similar complaints were filed in Louisiana. The plaintiffs, former employees of some of the defendants, generally allege that the defendants used or manufactured asbestos containing drilling mud additives for use in connection with drilling operations, claiming negligence, products liability, strict liability and claims allowed under the Jones Act and general maritime law. The plaintiffs generally seek awards of unspecified compensatory and punitive damages, but the court‑appointed special master has ruled that a Jones Act employer defendant, such as us, cannot be sued for punitive damages. At March 31, 2018, eight plaintiffs have claims pending in Louisiana in which we have or may have an interest. We intend to defend these lawsuits vigorously, although we can provide no assurance as to the outcome. We historically have maintained broad liability insurance, although we are not certain whether insurance will cover the liabilities, if any, arising out of these claims. Based on our evaluation of the exposure to date, we do not expect the liability, if any, resulting from these claims to have a material adverse effect on our condensed consolidated statement of financial position, results of operations or cash flows. One of our subsidiaries has been named as a defendant, along with numerous other companies, in lawsuits arising out of the subsidiary’s manufacture and sale of heat exchangers, and involvement in the construction and refurbishment of major industrial complexes alleging bodily injury or personal injury as a result of exposure to asbestos. As of March 31, 2018, the subsidiary was a defendant in approximately 98 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 and its operations were discontinued in 1989, and the subsidiary has no remaining assets other than insurance policies, rights and proceeds, including (i) certain policies subject to litigation and (ii) certain rights and proceeds held directly or indirectly through a qualified settlement fund. The subsidiary has in excess of $1.0 billion in insurance limits potentially available to the subsidiary. Although not all of the policies may be fully available due to the insolvency of certain insurers, we believe that the subsidiary will have sufficient funding directly or indirectly, including from settlements and payments from insurers, assigned rights from insurers and coverage‑in‑place settlement agreements with insurers to respond to these claims. While we cannot predict or provide assurance as to the outcome of these matters, we do not expect the ultimate liability, if any, resulting from these claims to have a material adverse effect on our 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 March 31, 2018, the aggregate tax assessment was for BRL 534 million, equivalent to approximately $162 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. In November 2017, the Third Chamber of the Taxpayer’s Council for administrative proceedings ruled in our favor on the validity of the initial tax claims. The ruling is subject to appeal by the state tax authorities. 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. Global Marine litigation—On November 28, 2017, Wilmington Trust Company, in its capacity as trustee, filed a lawsuit in the Supreme Court of the State of New York, County of New York, against Global Marine Inc. (“Global Marine”), one of our wholly owned, indirect subsidiaries, seeking a declaratory judgment that Global Marine is in default under the indenture governing its $300 million of outstanding 7.00% Notes due June 2028. We disagree with the assertions in the lawsuit and believe that Global Marine is in compliance with the indenture and has meritorious defenses against these allegations, although it can make no assurance regarding the outcome of the lawsuit, including the actual amount that would be due in the event that the lawsuit is successful. The notes are neither guaranteed by, nor recourse to, Transocean Ltd. or our other subsidiaries. The claimants seek payment prior to the scheduled maturity of the principal amount of notes outstanding and accrued but unpaid interest as well as make‑whole amounts under the indenture. In addition, the acceleration of the amounts due under the indenture could, absent a waiver from the requisite lenders, result in an event of default under our currently undrawn Five ‑Year Revolving Credit Facility. We intend to vigorously defend the lawsuit. While we cannot predict or provide assurance as to the outcome of these proceedings, we do not expect the proceedings to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows. Other matters—We are involved in various tax matters, various regulatory matters, and a number of claims and lawsuits, asserted and unasserted, all of which have arisen in the ordinary course of our business. We do not expect the liability, if any, resulting from these other matters to have a material adverse effect on our 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 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 various hazardous waste disposal sites, including those described below. CERCLA is intended to expedite the remediation of hazardous substances without regard to fault. Potentially responsible parties (“PRPs”) for each site include present and former owners and operators of, transporters to and generators of the substances at the site. Liability is strict and can be joint and several. We have been named as a PRP in connection with a site located in Santa Fe Springs, California, known as the Waste Disposal, Inc. site. We and other PRPs have agreed with the Environmental Protection Agency (the “EPA”) and the DOJ to settle our potential liabilities for this site by agreeing to perform the remaining remediation required by the EPA. The parties to the settlement have entered into a participation agreement, which makes us liable for approximately eight percent of the remediation and related costs. The remediation is complete, and we believe our share of the future operation and maintenance costs of the site is not material. There are additional potential liabilities related to the site, but these cannot be quantified, and we have no reason at this time to believe that they will be material. One of our subsidiaries has been ordered by the California Regional Water Quality Control Board (“CRWQCB”) to develop a testing plan for a site known as Campus 1000 Fremont in Alhambra, California, which is now a part of the San Gabriel Valley, Area 3, Superfund site. We were also advised that one or more of our subsidiaries that formerly owned and operated the site would likely be named by the EPA as PRPs. The current property owner, an unrelated party, performed the required testing and detected no contaminants. In discussions with CRWQCB staff, we were advised of their intent to issue us a “no further action” letter, but it has not yet been received. Based on the test results, we would contest any potential liability. We have no knowledge at this time of the potential cost of any remediation, who else will be named as PRPs, and whether in fact any of our subsidiaries is a responsible party. The subsidiaries in question do not own any operating assets and have limited ability to respond to any liabilities. Resolutions of other claims by the EPA, the involved state agency or PRPs are at various stages of investigation. These investigations involve determinations of (a) the actual responsibility attributed to us and the other PRPs at the site, (b) appropriate investigatory or remedial actions and (c) allocation of the costs of such activities among the PRPs and other site users. Our ultimate financial responsibility in connection with those sites may depend on many factors, including (i) the volume and nature of material, if any, contributed to the site for which we are responsible, (ii) the number of other PRPs and their financial viability and (iii) the remediation methods and technology to be used. It is difficult to quantify with certainty the potential cost of these environmental matters, particularly in respect of remediation obligations. Nevertheless, based upon the information currently available, we believe that our ultimate liability arising from all environmental matters, including the liability for all other related pending legal proceedings, asserted legal claims and known potential legal claims that are likely to be asserted, is adequately accrued and should not have a material effect on our condensed consolidated statement of financial position, results of operations or cash flows. |

Financial Instruments | Note 14—Financial Instruments The carrying amounts and fair values of our financial instruments were as follows (in millions):
We estimated the fair value of each class of financial instruments, for which estimating fair value is practicable, by applying the following methods and assumptions: Cash and cash equivalents—The carrying amount of our cash and cash equivalents represents the historical cost, plus accrued interest. Our cash equivalents are primarily invested in short‑term time deposits and money market funds. The carrying amount of our cash and cash equivalents approximates fair value because of the short maturities of the instruments. At March 31, 2018 and December 31, 2017, the aggregate carrying amount of our cash equivalents was $2.0 billion and $2.1 billion, respectively. Short‑term investments—The carrying amount of our unrestricted short‑term investments represents the historical cost of the time deposits in which they are invested. The carrying amount of such short‑term investments approximates fair value because of the near‑term maturities of the instruments. Restricted cash and cash equivalents—The carrying amount of our restricted cash and cash equivalents, which are subject to restrictions due to collateral requirements, legislation, regulation or court order, approximates fair value due to the near‑term maturities of the instruments in which the restricted balances are held. At March 31, 2018, the aggregate carrying amount of such restricted cash and cash equivalents was $494 million, including $484 million and $10 million recorded in current assets and other assets, respectively. At December 31, 2017, the aggregate carrying amount of such restricted cash and cash equivalents was $456 million, including $440 million and $16 million recorded in current assets and other assets, respectively. Restricted investments—The carrying amount of our restricted investments, which are pledged for security of certain other credit arrangements, represents the amortized historical cost of the investment. The carrying amount of such restricted investments approximates fair value because of the near‑term maturities of the instruments. At March 31, 2018, the aggregate carrying amount of the restricted cash investments was $7 million, recorded in other assets. At December 31, 2017, the aggregate carrying amount of the restricted cash investments was $26 million and $7 million, recorded in current assets and other assets, respectively. Debt—The carrying amount of our debt represents the principal amount, net of unamortized discounts, premiums, debt issue costs and fair value adjustments. We measured the estimated fair value of our debt using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. Derivative instruments—The carrying amount of our derivative instruments represents the estimated fair value of such instruments. We measured the estimated fair value of our derivative instruments using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. |

Significant Accounting Policies (Policies) |
3 Months Ended |

Mar. 31, 2018 | |
Significant Accounting Policies | |
Presentation | 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 and Article 10 of Regulation S‑X of the U.S. Securities and Exchange Commission (“SEC”). 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 months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018, 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, 2017 and 2016 and for each of the three years in the period ended December 31, 2017, included in our annual report on Form 10‑K filed on February 21, 2018. |
Accounting estimates | Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted in the U.S., we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and assumptions, including those related to our allowance for doubtful accounts, materials and supplies obsolescence, property and equipment, assets held for sale, goodwill, income taxes, contingencies, share‑based compensation and postemployment benefit plans. We base our estimates and assumptions on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ from such estimates. |
Fair value measurements | Fair value measurements—We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market for the asset or liability. Our valuation techniques require inputs that we categorize using a three‑level hierarchy, from highest to lowest level of observable inputs, as follows: (1) significant observable inputs, including unadjusted quoted prices for identical assets or liabilities in active markets (“Level 1”), (2) significant other observable inputs, including direct or indirect market data for similar assets or liabilities in active markets or identical assets or liabilities in less active markets (“Level 2”) and (3) significant unobservable inputs, including those that require considerable judgment for which there is little or no market data (“Level 3”). When multiple input levels are required for a valuation, we categorize the entire fair value measurement according to the lowest level of input that is significant to the measurement even though we may have also utilized significant inputs that are more readily observable. |
Business combination | Business combination—In connection with our acquisition of Songa, we applied the acquisition method of accounting. Accordingly, we recorded the acquired assets and assumed liabilities at fair value and recognized goodwill to the extent the consideration transferred exceeded the fair value of the net assets acquired. We estimated the fair values of the acquired assets and assumed liabilities as of the date of the acquisition, and our estimates are subject to adjustment based on our final assessments of the fair values of property and equipment, intangible assets, liabilities and our evaluation of tax positions and contingencies, which are ongoing. We will complete our final assessments of the fair values of the acquired assets and assumed liabilities and our final evaluations of uncertain tax positions and contingencies within one year of the acquisition date. See Note 4—Business Combination. |
Goodwill | Goodwill—We conduct impairment testing for our goodwill annually as of October 1 and more frequently, on an interim basis, when an event occurs or circumstances change that indicate that the fair value of a reporting unit may have declined below its carrying value. We test goodwill at the reporting unit level, which is defined as an operating segment or one level below an operating segment that constitutes a business for which financial information is available and is regularly reviewed by management. We determined that we have a single reporting unit for this purpose. Before testing goodwill, we consider whether or not to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, as the result of our qualitative assessment, we determine that an impairment test is required, or, alternatively, if we elect to forgo the qualitative assessment, we record an impairment to goodwill to the extent the carrying amount of the reporting unit, including goodwill, exceeds the fair value of the reporting unit. At March 31, 2018, the carrying amount of our goodwill was $460 million. See Note 3—Accounting Standards Updates and Note 4—Business Combination. |
Contract intangible assets | Contract intangible assets—In connection with our acquisition of Songa, we recognized drilling contract intangible assets related to the acquired drilling contracts for future contract drilling services. The drilling contract intangible assets represent the amount by which the fixed dayrates of the acquired contracts were above the market dayrates that were available or expected to be available during the term of the contract for similar contracts, measured as of the acquisition date. We recognize the amortization on a straight‑line basis over the firm contract period as a component of contract drilling revenues. At March 31, 2018, the carrying amount of our drilling contract intangible assets was $613 million. See Note 4—Business Combination. |
Derivative instruments | Derivative instruments—We record derivatives on our consolidated balance sheet, measured at fair value. We recognize the gains and losses associated with changes in the fair value in current period earnings. See Note 10—Derivative Instruments. |
Capitalized interest | Capitalized interest—We capitalize interest costs for qualifying construction and upgrade projects and only capitalize interest costs during periods in which progress for the construction projects continues to be underway. As of March 31, 2018, we had ceased capitalization of interest costs on one of our two uncontracted newbuild drillships due to a pause in construction in progress. In the three months ended March 31, 2018 and 2017, we capitalized interest costs of $13 million and $30 million, respectively, for our construction work in progress. |
Reclassifications | Reclassifications—We have made certain reclassifications to prior period amounts to conform with the current period’s presentation. In our condensed consolidated balance sheet as of December 31, 2017, we reclassified certain balances receivable from non‑customers, totaling $45 million, from accounts receivable, net, to other current assets. Such reclassifications did not have a material effect on our condensed consolidated statement of financial position, results of operations or cash flows. |
