TRANSOCEAN LTD. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1—Nature of Business

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,” the “Company,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells. We specialize in technically demanding sectors 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 June 30, 2014, we owned or had partial ownership interests in and operated 77 mobile offshore drilling units associated with our continuing operations. At June 30, 2014, our fleet consisted of 46 High-Specification Floaters (Ultra-Deepwater, Deepwater and Harsh Environment semisubmersibles and drillships), 21 Midwater Floaters, and 10 High-Specification Jackups. At June 30, 2014, we also had nine Ultra-Deepwater drillships and five High-Specification Jackups under construction or under contract to be constructed. See Note 9—Drilling Fleet.

In February 2014, in connection with our efforts to discontinue non-strategic operations, we completed the sale of Applied Drilling Technology International Limited (“ADTI”), a United Kingdom (“U.K.”) company, which performs drilling management services in the North Sea. See Note 7—Discontinued Operations.

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 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 and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 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, 2013 and 2012 and for each of the three years in the period ended December 31, 2013 included in our annual report on Form 10-K filed on February 27, 2014.

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 discontinued operations, allowance for doubtful accounts, materials and supplies obsolescence, assets held for sale, property and equipment, investments, notes receivable, goodwill, income taxes, contingencies, share-based compensation, defined benefit pension plans and other postretirement benefits. We base our estimates and assumptions on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ from such estimates.

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

Consolidation—We consolidate entities in which we have a majority voting interest and entities that meet the criteria for variable interest entities for which we are deemed to be the primary beneficiary for accounting purposes. We eliminate intercompany transactions and accounts in consolidation. We apply the equity method of accounting for an investment in an entity if we have the ability to exercise significant influence over the entity that (a) does not meet the variable interest entity criteria or (b) meets the variable interest entity criteria, but for which we are not deemed to be the primary beneficiary. We apply the cost method of accounting for an investment in an entity if we do not have the ability to exercise significant influence over the unconsolidated entity. See Note 4—Variable Interest Entities.

Share-based compensation—In the three and six months ended June 30, 2014, we recognized share-based compensation expense of $23 million and $51 million, respectively. In the three and six months ended June 30, 2013, we recognized share-based compensation expense of $28 million and $49 million, respectively.

Capitalized interest—We capitalize interest costs for qualifying construction and upgrade projects. In the three and six months ended June 30, 2014, we capitalized interest costs on construction work in progress of $42 million and $76 million, respectively. In the three and six months ended June 30, 2013, we capitalized interest costs on construction work in progress of $16 million and $37 million, respectively.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—continued

(Unaudited)

Reclassifications—We have made certain reclassifications, which did not have an effect on net income, to prior period amounts to conform with the current period’s presentation, including certain reclassifications to our consolidated statements of operations and cash flows to present discontinued operations (see Note 7—Discontinued Operations) and reclassification of an intracompany note (see Note 16—Condensed Consolidating Financial Information). Other reclassifications did not have a material effect on our condensed consolidated statement of financial position, results of operations or cash flows.

Subsequent events—We evaluate subsequent events through the time of our filing on the date we issue our financial statements. See Note 17—Subsequent Events.

Note 3—New Accounting Pronouncements

Recently adopted accounting standards

Income taxes—Effective January 1, 2014, we adopted the accounting standards update that requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if net settlement is required or expected. The update is effective for interim and annual periods beginning on or after December 15, 2013. Our adoption did not have a material effect on our condensed consolidated balance sheets or the disclosures contained in our notes to condensed consolidated financial statements.

Recently issued accounting standards

Presentation of financial statements—Effective January 1, 2015, we will adopt the accounting standards update that changes the criteria for reporting discontinued operations. The update expands the disclosures for discontinued operations and requires new disclosures related to the disposal of individually significant components of an entity that do not qualify for discontinued operations. The update is effective for interim and annual periods beginning on or after December 15, 2014. We do not expect that our adoption will have a material effect on our condensed consolidated balance sheets or the disclosures contained in our notes to condensed consolidated financial statements.

Revenue from contracts with customers—Effective January 1, 2017, we will adopt the new accounting standards update that requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The update is effective for interim and annual periods beginning on or after December 15, 2016. We are evaluating the requirements to determine the effect such requirements may have on our revenue recognition policies.

Note 4—Variable Interest Entities

Consolidated variable interest entities— Angola Deepwater Drilling Company Limited (“ADDCL”), a consolidated Cayman Islands company, and Transocean Drilling Services Offshore Inc. (“TDSOI”), a consolidated British Virgin Islands company, are variable interest entities for which we are the primary beneficiary. Accordingly, we consolidate the operating results, assets and liabilities of ADDCL and TDSOI.

The carrying amounts associated with our consolidated variable interest entities, after eliminating the effect of intercompany transactions, were as follows (in millions):

	June 30, 2014		December 31, 2013
Assets	$	1,254	$	1,280
Liabilities		88		261
Net carrying amount	$	1,166	$	1,019

Note 5—Impairments

Assets held for sale—In the six months ended June 30, 2014, we recognized an aggregate loss of $65 million ($0.19 per diluted share), which had no tax effect, associated with the impairment of the Midwater Floater Sedneth 701 and the High-Specification Jackup GSF Magellan, along with related equipment, which were classified as assets held for sale at the time of impairment. We measured the impairments of the drilling units and related equipment as the amount by which the carrying amount exceeded the estimated fair value less costs to sell. We estimated the fair value of the assets using significant other observable inputs, representative of Level 2 fair value measurements, including a binding sale and purchase agreement for the drilling unit and related equipment or indicative market values for the drilling unit and related equipment to be sold for scrap value.

In the three and six months ended June 30, 2013, we recognized an aggregate loss of $37 million ($0.10 per diluted share from continuing operations), which had no tax effect, associated with the impairment of the Deepwater Floater Sedco 709 and the Midwater Floaters C. Kirk Rhein, Jr. and Sedco 703, all of which were classified as assets held for sale at the time of impairment. We measured the impairments of the drilling units and related equipment as the amount by which the carrying amounts exceeded the estimated fair values less costs to sell. We estimated the fair values of the assets using significant other observable inputs, representative of Level 2 fair value measurements, including nonbinding sale and purchase agreements for the drilling units and related equipment to be sold for scrap value.

Note 6—Income Taxes

Tax 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. At the federal level, qualifying net dividend income and net capital gains on the sale of qualifying investments in subsidiaries are exempt from Swiss federal income tax. Consequently, Transocean Ltd. expects dividends from its subsidiaries and capital gains from sales of investments in its subsidiaries to be exempt from 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. The relationship between our provision for or benefit from income taxes and our income or loss before income taxes can vary significantly from period to period considering, among other factors, (a) the overall level of income before income taxes, (b) changes in the blend of income that is taxed based on gross revenues rather than income before taxes, (c) rig movements between taxing jurisdictions and (d) our rig operating structures. Generally, our annual marginal tax rate is lower than our annual effective tax rate.

In the six months ended June 30, 2014 and 2013, our estimated annual effective tax rates were 13.8 percent and 21.7 percent, respectively. These rates were based on estimated annual income before income taxes for each period after adjusting for various discrete items, including certain immaterial adjustments to prior period tax expense. See Note 17—Subsequent Events.

Unrecognized tax benefits—The liabilities related to our unrecognized tax benefits, including related interest and penalties that we recognize as a component of income tax expense, were as follows (in millions):

		June 30, 2014		December 31, 2013
Unrecognized tax benefits, excluding interest and penalties	$	330	$	326
Interest and penalties		169		176
Unrecognized tax benefits, including interest and penalties	$	499	$	502

In the year ending December 31, 2014, it is reasonably possible that our existing liabilities for unrecognized tax benefits may increase or decrease primarily due to the progression of open audits or the expiration of statutes of limitation. However, we cannot reasonably estimate a range of potential changes in our existing liabilities for unrecognized tax benefits due to various uncertainties, such as the unresolved nature of various audits.

Tax returns—We file federal and local tax returns in several jurisdictions throughout the world. With few exceptions, we are no longer subject to examinations of our U.S. and non-U.S. tax matters for years prior to 2010.

Our tax returns in the major jurisdictions in which we operate, other than the U.S., Norway and Brazil, which are mentioned below, are generally subject to examination for periods ranging from three to six years. We have agreed to extensions beyond the statute of limitations in two major jurisdictions for up to 19 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 outcome of these proceedings, we do not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations, although it may have a material adverse effect on our consolidated statement of cash flows.

U.S. tax investigations—During the six months ended June 30, 2014, we received an assessment from the U.S. tax authorities related to our 2010 and 2011 U.S. federal income tax returns. The significant issue raised in the assessment relates to transfer pricing for certain charters of drilling rigs between our subsidiaries. This issue, if successfully challenged, would result in net adjustments of approximately $290 million of additional taxes, excluding interest and penalties. An unfavorable outcome on these adjustments could result in a material adverse effect on our consolidated statement of financial position, results of operations or cash flows. Furthermore, if the authorities were to continue to pursue these positions with respect to subsequent years and were successful in such assertions, our effective tax rate on worldwide earnings with respect to years following 2011 could increase substantially, and could have a material adverse effect on our consolidated results of operations or cash flows. We believe our U.S. federal income tax returns are materially correct as filed, and we intend to continue to vigorously defend against all such claims to the contrary.

Norway tax investigations and trial—Norwegian civil tax and criminal authorities are investigating various transactions undertaken by our subsidiaries in 1999, 2001 and 2002 as well as the actions of certain employees of our former external tax advisors on these transactions. The authorities issued tax assessments as follows: (a) NOK 684 million, equivalent to approximately $114 million, plus interest, related to the migration of our subsidiary that was previously subject to tax in Norway, (b) NOK 412 million, equivalent to approximately $69 million, plus interest, related to a 2001 dividend payment and (c) NOK 43 million, equivalent to approximately $7 million, plus interest, related to certain foreign exchange deductions and dividend withholding tax. We provided a parent company guarantee in the amount of NOK 699 million, equivalent to approximately $117 million with respect to one of these tax disputes. In November 2012, the Norwegian district court in Oslo heard the civil tax case regarding the disputed tax assessment of NOK 684 million related to the migration of our subsidiary. On March 1, 2013, the Norwegian district court in Oslo overturned the initial civil tax assessment and ruled in our favor, and the tax authorities filed an appeal. On June 26, 2014, the Norwegian district court in Oslo ruled that our subsidiary was liable for the civil tax assessment of NOK 412 million, equivalent to approximately $69 million, but waived all penalties and interest. We intend to file an appeal and to take other appropriate action to continue to support our position that our Norwegian tax returns are materially correct as filed.

In June 2011, the Norwegian authorities issued criminal indictments against two of our subsidiaries alleging misleading or incomplete disclosures in Norwegian tax returns for the years 1999 through 2002, as well as inaccuracies in Norwegian statutory financial statements for the years ended December 31, 1996 through 2001. Two employees of our former external tax advisors were also issued criminal indictments with respect to the disclosures in our tax returns, and our former external Norwegian tax attorney was issued criminal indictments related to certain of our restructuring transactions and the 2001 dividend payment. In January 2012, the Norwegian authorities supplemented the previously issued criminal indictments by issuing a financial claim of NOK 1.8 billion, equivalent to approximately $300 million, jointly and severally, against our two subsidiaries, the two external tax advisors and the external tax attorney. In February 2012, the authorities dropped the previously existing civil tax claim related to a certain restructuring transaction. In April 2012, the Norwegian tax authorities supplemented the previously issued criminal indictments against our two subsidiaries by extending a criminal indictment against a third subsidiary, alleging misleading or incomplete disclosures in Norwegian tax returns for the years 2001 and 2002. The criminal trial commenced in December 2012. In May 2013, the Norwegian authorities dropped the financial claim of NOK 1.8 billion against one of our subsidiaries and the criminal case related to the migration case of another subsidiary. The criminal trial proceedings ended in September 2013. The Norwegian authorities subsequently suggested, if we were found guilty, that the court assess criminal penalties of NOK 230 million, equivalent to approximately $38 million, against three of our subsidiaries in addition to any civil tax penalties and the financial claim. We believe our Norwegian tax returns are materially correct as filed, and we intend to continue to vigorously contest any assertions to the contrary by the Norwegian civil and criminal authorities in connection with the various transactions being investigated. An unfavorable outcome on the Norwegian civil or criminal tax matters could result in a material adverse effect on our consolidated statement of financial position, results of operations or cash flows. See Note 17—Subsequent Events.

Brazil tax investigations—Certain of our Brazilian income tax returns for the years 2000 through 2004 are currently under examination. In December 2005, the Brazilian tax authorities issued an aggregate tax assessment of BRL 694 million, equivalent to approximately $315 million, including a 75 percent penalty and interest. On January 25, 2008, we filed a protest letter with the Brazilian tax authorities, and we are currently engaged in the appeals process. On May 19, 2014, with respect to our Brazilian income tax returns for the years 2009 and 2010, the Brazilian tax authorities issued an aggregate tax assessment of BRL 121 million, equivalent to approximately $55 million, including a 75 percent penalty and interest. On June 18, 2014, we filed a protest letter with the Brazilian tax authorities. We believe our returns are materially correct as filed, and we are vigorously contesting these assessments. An unfavorable outcome on these proposed assessments could result in a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

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

Standard jackup and swamp barge contract drilling services

Overview—In September 2012, in connection with our efforts to dispose of non-strategic assets and to reduce our exposure to low-specification drilling units, we committed to a plan to discontinue operations associated with the standard jackup and swamp barge asset groups, components of our contract drilling services operating segment.

Sale transactions with Shelf Drilling—In November 2012, we completed the sale of 38 drilling units to Shelf Drilling Holdings, Ltd. (“Shelf Drilling”). For a transition period following the completion of the sale transactions, we agreed to continue to operate a substantial portion of the standard jackups under operating agreements with Shelf Drilling and to provide certain other transition services to Shelf Drilling. Under the operating agreements, we have agreed to remit the collections from our customers under the associated drilling contracts to Shelf Drilling, and Shelf Drilling has agreed to reimburse us for our direct costs and expenses incurred while operating the standard jackups on behalf of Shelf Drilling with certain exceptions. Amounts due to Shelf Drilling under the operating agreements and transition services agreement may be contractually offset against amounts due from Shelf Drilling. The costs to us for providing such operating and transition services, including allocated indirect costs, have exceeded the amounts we have received from Shelf Drilling for providing such services.

Under the operating agreements, we agreed to continue to operate these standard jackups on behalf of Shelf Drilling until the earlier of expiration or novation of the underlying drilling contracts by Shelf Drilling. As of June 30, 2014, we operated two standard jackups under operating agreements with Shelf Drilling, and we expect to complete performing services under such operating agreements before December 31, 2014. Until the expiration or novation of such drilling contracts, we retain possession of the materials and supplies associated with the standard jackups that we operate under the operating agreements. In the three and six months ended June 30, 2014, we received cash proceeds of $22 million and $25 million, respectively, and recognized net gains of $1 million and $2 million, respectively, which had no tax effect, associated with the sale of equipment and materials and supplies to Shelf Drilling upon expiration or novation of the drilling contracts. In the three and six months ended June 30, 2013, we recognized a net gain of $3 million ($0.01 per diluted share), which had no tax effect, associated with the disposal of assets unrelated to rig sales. At June 30, 2014 and December 31, 2013, the materials and supplies associated with the drilling units that we operated under operating agreements with Shelf Drilling had an aggregate carrying amount of $2 million and $19 million, respectively. Under a transition services agreement, we provided certain transition services through May 2014.

For a period through November 2015, we agreed to provide to Shelf Drilling up to $125 million of financial support by maintaining letters of credit, surety bonds and guarantees for various contract bidding and performance activities associated with the drilling units sold to Shelf Drilling and in effect at the closing of the sale transactions. At the time of the sale transactions, we had $113 million of outstanding letters of credit, issued under our committed and uncommitted credit lines, in support of rigs sold to Shelf Drilling. Included within the $125 million maximum amount, we agreed to provide up to $65 million of additional financial support in connection with any new drilling contracts related to such drilling units. Shelf Drilling is required to reimburse us in the event that any of these instruments are called. At June 30, 2014 and December 31, 2013, we had $105 million and $104 million, respectively, of outstanding letters of credit, issued under our committed and uncommitted credit lines, in support of drilling units sold to Shelf Drilling. See Note 13—Commitments and Contingencies.

Other dispositions—During the six months ended June 30, 2013, we completed the sale of the Standard Jackups D.R. Stewart, Interocean III and GSF Adriatic VIII along with related equipment. In the six months ended June 30, 2013, in connection with the disposal of these assets, we received aggregate net cash proceeds of $63 million, and we recognized an aggregate net gain of $15 million ($0.04 per diluted share), which had no tax effect.

Drilling management services

Overview—In February 2014, in connection with our efforts to discontinue non-strategic operations, we completed the sale of ADTI, which performs drilling management services in the North Sea. As a result of the sale, we reclassified the results of operations of our drilling management services operating segment to discontinued operations for all periods presented. At December 31, 2013, the carrying amount of assets of the drilling management services operating segment was $6 million.

Disposition—In the six months ended June 30, 2014, we received net cash proceeds of $11 million associated with the sale of the drilling management services business. In the three and six months ended June 30, 2014, in connection with the sale, we recognized a net loss of $1 million and $12 million ($0.03 per diluted share), respectively, which had no tax effect. Following the completion of the sale transaction, we agreed to provide a limited guarantee in favor of one customer through completion of the current drilling project, which is expected to occur in the fourth quarter of 2014. We also agreed to provide a $15 million working capital line of credit to the buyer through March 2016. We earn interest on the outstanding borrowings at a fixed rate of 8.3 percent per annum, payable quarterly. At June 30, 2014, ADTI had borrowings of $15 million outstanding under the working capital line of credit, recorded in other assets.

New Five-Year Revolving Credit Facility—In June 2014, we entered into an amended and restated bank credit agreement, which established a $3.0 billion unsecured five-year revolving credit facility, that is scheduled to expire on June 28, 2019 (the “New Five-Year Revolving Credit Facility”). Among other things, the New 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 New Five-Year Revolving Credit Facility also includes a covenant imposing a maximum debt to tangible capitalization ratio of 0.6 to 1.0. Borrowings under the Five-Year Revolving Credit Facility are subject to acceleration upon the occurrence of an event of default, Borrowings are guaranteed by Transocean Ltd. and may be prepaid in whole or in part without premium or penalty.

We may borrow under the New Five-Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate (“LIBOR”) plus a margin (the “New Five-Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the credit rating of our non-credit enhanced senior unsecured long-term debt (“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 New 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 depending on our Debt Rating. At June 30, 2014, based on our Debt Rating on that date, the New Five-Year Revolving Credit Facility Margin was 1.5 percent and the facility fee was 0.225 percent. At June 30, 2014, we had no borrowings outstanding, we had $20 million in letters of credit issued, and we had $3.0 billion of available borrowing capacity under the New Five-Year Revolving Credit Facility.

Former Five-Year Revolving Credit Facility—We had a $2.0 billion five-year revolving credit facility, established under a bank credit agreement dated November 1, 2011, as amended, that was scheduled to expire on November 1, 2016 (the “Former Five-Year Revolving Credit Facility”). In June 2014, we replaced the Former Five-Year Revolving Credit Facility with the New Five-Year Revolving Credit Facility.

Former Three-Year Secured Revolving Credit Facility—We had a $900 million three-year secured revolving credit facility, established under a bank credit agreement dated October 25, 2012, that was scheduled to expire on October 25, 2015 (the “Former Three-Year Secured Revolving Credit Facility”). Borrowings under the Former Three-Year Secured Revolving Credit Facility were secured by the Ultra-Deepwater Floaters Deepwater Champion, Discoverer Americas and Discoverer Inspiration. At December 31, 2013, the aggregate carrying amount of Deepwater Champion, Discoverer Americas and Discoverer Inspiration was $2.2 billion. In June 2014, we terminated the Former Three-Year Secured Revolving Credit Facility and the related security agreements. No borrowings were outstanding under the Former Three-Year Secured Revolving Credit Facility at the time of its termination. In the three and six months ended June 30, 2014, we recognized a loss of $4 million associated with the early termination of the Former Three-Year Secured Revolving Credit Facility.

ADDCL Credit Facilities—ADDCL had a senior secured credit facility, comprised of Tranche A for $215 million and Tranche C for $399 million, established under a bank credit agreement dated June 2, 2008 that was scheduled to expire in December 2017 (the “ADDCL Primary Loan Facility”). Unaffiliated financial institutions provided the commitment for and borrowings under Tranche A, and one of our subsidiaries provided the commitment for Tranche C. ADDCL also had a $90 million secondary credit facility, established under a bank credit agreement dated June 2, 2008 that was scheduled to expire in December 2015 (the “ADDCL Secondary Loan Facility” and together with the ADDCL Primary Loan Facility, the “ADDCL Credit Facilities”). One of our subsidiaries provided 65 percent of the total commitment under the ADDCL Secondary Loan Facility. At December 31, 2013, borrowings of $534 million and $80 million were outstanding under the ADDCL Primary Loan Facility and the ADDCL Secondary Loan Facility, respectively, of which $399 million and $52 million were provided by one of our subsidiaries and were eliminated in consolidation. In February 2014, we repaid the outstanding borrowings under the ADDCL Credit Facilities and terminated the bank credit agreements under which the credit facilities were established.

ADDCL was required to maintain certain cash balances in restricted accounts for the payment of the scheduled installments on the ADDCL Credit Facilities. At December 31, 2013, ADDCL had restricted cash investments of $20 million. The restricted cash investments were released as a result of our repayment of borrowings under the ADDCL Credit Facilities.

Eksportfinans Loans—We have borrowings under the Loan Agreement dated September 12, 2008 and the Loan Agreement dated November 18, 2008 (together, the “Eksportfinans Loans”). At June 30, 2014 and December 31, 2013, aggregate borrowings of NOK 3.2 billion and NOK 3.6 billion, equivalent to approximately $519 million and $594 million, respectively, were outstanding under the Eksportfinans Loans.

The Eksportfinans Loans require collateral to be held by a financial institution through expiration (the “Aker Restricted Cash Investments”). At June 30, 2014 and December 31, 2013, the aggregate principal amount of the Aker Restricted Cash Investments was NOK 3.2 billion and NOK 3.6 billion, equivalent to approximately $519 million and $594 million, respectively.

Note 11—Derivatives and Hedging

Derivatives designated as hedging instruments—During the six months ended June 30, 2014, we entered into interest rate swaps, which are designated and qualify as a fair value hedge, to reduce our exposure to changes in the fair value of the 6.0% Senior Notes due March 2018 and the 6.5% Senior Notes due November 2020. The interest rate swaps have aggregate notional amounts equal to the corresponding face values of the hedged instruments and have stated maturities that coincide with those of the hedged instruments. We have determined that the hedging relationships qualify for, and we have applied, the shortcut method of accounting under which the interest rate swaps are considered to have no ineffectiveness and no ongoing assessment of effectiveness is required. Accordingly, changes in the fair value of the interest rate swaps recognized in interest expense offset the changes in the fair value of the hedged fixed-rate notes.

At June 30, 2014, the aggregate notional amounts and the weighted average interest rates associated with our derivatives designated as hedging instruments were as follows (in millions, except weighted average interest rates):

	Pay						Receive
	Aggregate notional amount		Fixed or variable rate	Weighted average rate			Aggregate notional amount		Fixed or variable rate	Weighted average rate
Interest rate swaps, fair value hedge	$	1,050	Variable		4.71	%	$	1,050	Fixed		6.14	%

At June 30, 2014, our derivatives designated as hedging instruments had an aggregate carrying amount of $6 million, measured at fair value, recorded in other assets.

Note 12—Postemployment Benefit Plans

We have several defined benefit pension plans, both funded and unfunded, covering substantially all of our U.S. employees, including certain frozen plans, assumed in connection with our mergers, that cover certain current employees and certain former employees and directors of our predecessors (the “U.S. Plans”). We also have various defined benefit plans in the U.K., Norway, Nigeria, Egypt and Indonesia that cover our employees in those areas (the “Non-U.S. Plans”). Additionally, we offer several unfunded contributory and noncontributory other postretirement employee benefit plans covering substantially all of our U.S. employees (the “OPEB Plans”).

The components of net periodic benefit costs, before tax, and funding contributions for these plans were as follows (in millions):

In June 2014, we committed to freeze benefits and, as a result, remeasured the funded status of our qualified defined benefit pension plan in the U.S., which covers substantially all U.S. employees, and one of our unfunded supplemental benefit plans. We also committed to enhance the benefits under our defined contribution plan in the U.S. These amendments will be effective as of January 1, 2015. As a result, in the three and six months ended June 30, 2014, we reduced the aggregate liability by $78 million and $73 million, respectively, with a corresponding entry to accumulated other comprehensive loss. As of June 30, 2014 and December 31, 2013, our defined benefit pension and other post retirement plans had an aggregate liability of $305 million and $417 million, respectively, representing the aggregate projected benefit obligation, net of the aggregate fair value of plan assets.

Note 13—Commitments and Contingencies

Macondo well incident settlement obligations

On January 3, 2013, we reached an agreement with the U.S. Department of Justice (“DOJ”) to resolve certain outstanding civil and potential criminal charges against us arising from the Macondo well incident. As part of this resolution, we agreed to a guilty plea (“Plea Agreement”) and a civil consent decree (“Consent Decree”) by which, among other things, we agreed to pay $1.4 billion in fines, recoveries and civil penalties, plus interest at a fixed rate of 2.15 percent, in scheduled payments through February 2017.

In the six months ended June 30, 2014, we made an aggregate cash payment of $60 million in satisfaction of amounts due under the Plea Agreement, including $53 million to the National Fish and Wildlife Foundation and $7 million to the National Academy of Sciences. In the three and six months ended June 30, 2013, we made an aggregate cash payment of $160 million in satisfaction of amounts due under the Plea Agreement, including $100 million for the payment of the criminal fine, $58 million for the initial payment to the National Fish and Wildlife Foundation and $2 million for the initial payment to the National Academy of Sciences.

In the six months ended June 30, 2014 and 2013, we paid $412 million and $404 million, including interest, in satisfaction of amounts due under the Consent Decree.

At June 30, 2014, the aggregate future payments required under our outstanding settlement obligations under the Plea Agreement and the Consent Decree, excluding interest, were as follows (in millions):

	Plea Agreement		Consent Decree		Settlement obligations
Twelve months ending June 30,
2015	$	60	$	200	$	260
2016		60		—		60
2017		60		—		60
Total settlement obligations	$	180	$	200	$	380

The resolution with the DOJ of such civil and potential criminal claims did not include potential claims arising from the False Claims Act investigation. As part of the settlement discussions, however, we inquired whether the U.S. intends to pursue any actions under the False Claims Act as discussed below. In response, the DOJ sent us a letter stating that the Civil Division of the DOJ, based on facts then known, was no longer pursuing any investigation or claims, and did not have any present intention to pursue any investigation or claims, under the False Claims Act against the various Transocean entities for their involvement in the Macondo well incident.

We also agreed that payments made pursuant to the Plea Agreement or the Consent Decree are not deductible for tax purposes and that payments made pursuant to the Consent Decree are not to be used as a basis for indemnity or reimbursement from BP or other non-insurer defendants named in the complaint by the U.S.

Plea Agreement—Pursuant to the Plea Agreement, which was accepted by the court on February 14, 2013, one of our subsidiaries pled guilty to one misdemeanor count of negligently discharging oil into the U.S. Gulf of Mexico, in violation of the Clean Water Act (“CWA”). We agreed to pay a criminal fine of $100 million and to consent to the entry of an order requiring us to pay a total of $150 million to the National Fish & Wildlife Foundation and $150 million to the National Academy of Sciences.

Our subsidiary also agreed to be subject to probation through February 2018. The DOJ agreed, subject to the provisions of the Plea Agreement, not to further prosecute us for certain conduct generally regarding matters under investigation by the DOJ’s Deepwater Horizon Task Force. In addition, we agreed to continue to cooperate with the Deepwater Horizon Task Force in any ongoing investigation related to or arising from the accident.

Consent Decree—Pursuant to the Consent Decree, which was approved by the court on February 19, 2013, we agreed to take specified actions relating to operations in U.S. waters, including, among other things, the design and implementation of, and compliance with, additional systems and procedures; blowout preventer certification and reports; measures to strengthen well control competencies, drilling monitoring, recordkeeping, incident reporting, risk management and oil spill training, exercises and response planning; communication with operators; alarm systems; transparency and responsibility for matters relating to the Consent Decree; and technology innovation, with a first emphasis on more efficient, reliable blowout preventers. We agreed to submit a performance plan (the “Performance Plan”) for approval by the DOJ within 120 days after the date of entry of the Consent Decree. On June 14, 2013, we submitted our proposed Performance Plan, containing among other required items, interim milestones for actions in specified areas and a proposed schedule for reports required under the Consent Decree. On January 2, 2014, the DOJ approved the Performance Plan.

The Consent Decree also provides for the appointment of (i) an independent auditor to review, audit and report on our compliance with the injunctive provisions of the Consent Decree and (ii) an independent process safety consultant to review, report on and assist with respect to the process safety aspects of the Consent Decree, including operational risk identification and risk management. The Consent Decree requires certain plans, reports and submissions be made and be acceptable to the U.S. and also requires certain publicly available filings. On March 31, 2014, the DOJ approved the appointment of Labyrinth Group to act as the independent auditor. On May 12, 2014, the DOJ approved the appointment of Mr. Malcolm Sharples as the independent process safety consultant.

Under the terms of the Consent Decree, the U.S. agreed not to sue Transocean Ltd. and certain of our subsidiaries and certain related individuals for civil or administrative penalties for the Macondo well incident under specified provisions of the CWA, the Outer Continental Shelf Lands Act (“OSCLA”), the Endangered Species Act, the Marine Mammal Protection Act, the National Marine Sanctuaries Act, the federal Oil and Gas Royalty Management Act, the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), the Emergency Planning and Community Right-to-Know Act (“EPCRA”) and the Clean Air Act. In addition, the Consent Decree resolved our appeal of the incidents of noncompliance under the OSCLA issued by the Bureau of Safety and Environmental Enforcement on October 12, 2011 without any admission of liability by us, and we subsequently dismissed our appeal.

The Consent Decree did not resolve the rights of the U.S. with respect to all other matters, including certain liabilities under the Oil Pollution Act of 1990 (the “OPA”) for removal costs or resulting from a natural resources damages assessment (“NRDA”). However, the district court previously held that we are not liable under the OPA for damages caused by subsurface discharge from the Macondo well. If this ruling is upheld on appeal, our NRDA liability would be limited to any such damages arising from the above-surface discharge. The court has not yet ruled whether we could be liable for removal costs to the U.S. or any state or local government as an operator of the Macondo well.

We may request termination of the Consent Decree after we have: (i) completed timely the civil penalty payment requirements of the Consent Decree; (ii) operated under a fully approved Performance Plan required under the Consent Decree through a five-year performance period ending January 2, 2019; (iii) complied with the terms of the Performance Plan and certain provisions of the Consent Decree, generally relating to a framework and outline of measures to improve performance, for at least 12 consecutive months prior to seeking termination; and (iv) complied with the other requirements of the Consent Decree, including payment of any stipulated penalties and compliant reporting.

EPA Agreement—On February 25, 2013, we and the U.S. Environmental Protection Agency (“EPA”) entered into an administrative agreement (the “EPA Agreement”), which has a five-year term. The EPA Agreement resolved all matters relating to suspension, debarment and statutory disqualification arising from the matters contemplated by the Plea Agreement. Subject to our compliance with the terms of the EPA Agreement, the EPA agreed that it will not suspend, debar or statutorily disqualify us and will lift any existing suspension, debarment or statutory disqualification.

In the EPA Agreement, we agreed to, among other things, (1) comply with our obligations under the Plea Agreement and the Consent Decree; (2) continue the implementation of certain programs and systems, including the scheduled revision of our environmental management system and maintenance of certain compliance and ethics programs; (3) comply with certain employment and contracting procedures; (4) engage independent compliance auditors and a process safety consultant to, among other things, assess and report to the EPA on our compliance with the terms of the Plea Agreement, the Consent Decree and the EPA Agreement; and (5) give reports and notices with respect to various matters, including those relating to compliance, misconduct, legal proceedings, audit reports, the EPA Agreement, the Consent Decree and the Plea Agreement. Subject to certain exceptions, the EPA Agreement prohibits us from entering into, extending or engaging in certain business relationships with individuals or entities that are debarred, suspended, proposed for debarment or similarly restricted.

Macondo well incident contingencies

Overview—We have recognized a liability for estimated loss contingencies associated with litigation and investigations resulting from the incident that we believe are probable and for which a reasonable estimate can be made. At June 30, 2014 and December 31, 2013, the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $432 million and $464 million, respectively, recorded in other current liabilities. The litigation and investigations also give rise to certain loss contingencies that we believe are either reasonably possible or probable but for which we do not believe a reasonable estimate can be made. Although we have not recognized a liability for such loss contingencies, these contingencies could result in liabilities that we ultimately recognize.

We have also recognized an asset associated with the portion of our estimated losses that we believe is probable of recovery from insurance. At June 30, 2014 and December 31, 2013, the insurance recoverable asset was $10 million, recorded in other assets. 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. As a result of new information or future developments, we may increase our estimated loss contingencies arising out of the Macondo well incident or reduce our estimated recoveries from insurance, and the resulting losses could have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

On December 21, 2012, the MDL Court granted final approval of the economic and property damage class settlement between BP and the PSC. Various parties who objected to the BP/PSC Settlement have filed appeals in the U.S. Court of Appeals for the Fifth Circuit (the “Fifth Circuit”) challenging the MDL Court’s final approval of the BP/PSC Settlement. BP filed appeals in the Fifth Circuit challenging the manner in which the BP/PSC Settlement has been interpreted by the MDL Court with respect to business economic loss claims (“BEL Claims”). In these appeals, BP argued that, if the MDL Court’s interpretation of the settlement with respect to BEL Claims was not overturned, the entire BP/PSC Settlement was invalid and should not have been approved. On October 2, 2013, a panel of the Fifth Circuit issued an opinion questioning the manner in which the settlement had been interpreted with respect to BEL Claims. On December 24, 2013, the MDL Court issued an order (the “BEL Order”) regarding the BEL Claims in which it ruled that (a) variable profits should be determined under the settlement agreement by matching revenue with corresponding expenses; (b) BP was judicially estopped from arguing that claimants were required to submit evidence to prove causation; and (c) as construed by the court, the settlement was consistent with Article III of the U.S. Constitution, Rule 23, and the U.S. Rules Enabling Act. BP appealed the BEL Order, but on March 3, 2014, the same panel of the Fifth Circuit affirmed the MDL Court’s ruling that claimants were not required to submit evidence of causation.

On January 10, 2014, another panel of the Fifth Circuit affirmed the MDL Court’s final approval of the BP/PSC Settlement. Thereafter, BP and certain plaintiffs who objected to the settlement filed petitions seeking review by the entire Fifth Circuit of the legal validity of the BP/PSC Settlement. On May 20, 2014, the Fifth Circuit denied BP’s petitions. On May 21, 2014, BP filed a motion with the Fifth Circuit to stay the mandate and stop further payments of BEL Claims pending the filing and disposition of a petition for writ of certiorari to the U.S. Supreme Court. On May 27, 2014, the Fifth Circuit denied BP’s application. BP then appealed to the U.S. Supreme Court for a stay, but on June 9, 2014, the U.S. Supreme Court denied BP’s application.

In December 2012, in response to the BP/PSC Settlement, we filed three motions seeking partial summary judgment on various claims, including punitive damages claims. If successful, these motions would eliminate or reduce our exposure to punitive damages. The MDL Court has not ruled on these motions.

In May 2013, we filed a motion seeking partial summary judgment on claims asserted by BP against us seeking damages from loss of the well and for source-control and cleanup costs (the “Direct Damages” claims). The Direct Damages claims are included in the claims BP assigned to the economic and property damages settlement class. The motion argues that BP released the Direct Damages claims in its contract with us and that the release is enforceable even if we are found grossly negligent. Some courts have held that such agreements will not be enforced if the defendant is found grossly negligent. The MDL Court has not yet ruled on this motion.

The first phase of the trial began on February 25, 2013 and testimony concluded on April 17, 2013. This phase addressed fault issues, including negligence, gross negligence, or other bases of liability of the various defendants with respect to the cause of the blowout and the initiation of the oil spill, as well as limitation of liability issues. In June and July 2013, the parties filed post-trial briefs and proposed findings of fact and conclusions of law. The MDL Court has not yet ruled on the issues tried in the first phase of the trial.

If the MDL Court finds in this phase of the trial that we were grossly negligent, we will be exposed to at least three litigation risks: (1) the MDL Court could award punitive damages under general maritime law to plaintiffs who own property damaged by oil and to plaintiffs who are commercial fishermen; (2) the MDL Court could find that our gross negligence voids the release BP gave us in the drilling contract for direct claims by BP, which BP has assigned to the plaintiffs in the BP/PSC Settlement; and (3) we could be liable for all other oil pollution damages claims, including claims resulting from NRDA, if the court of appeals were to reverse a prior ruling that BP owes us indemnity for these claims even in the event of gross negligence. This potential liability for all other oil pollution damage claims could also arise regardless of a finding as to our gross negligence, for which we believe we are owed indemnity, if the MDL Court were in any event to find a core breach of the drilling contract, thereby nullifying our indemnity. Our four pending motions for partial judgment on the pleadings or partial summary judgment, if successful, could reduce or eliminate our exposure to these claims. A finding of gross negligence against us or against BP or a finding that either we or BP violated certain safety regulations would also result in the removal of the statutory liability caps under OPA. Under the MDL Court’s present ruling, however, our liability for damages under OPA is limited to damages caused by discharge on or above the surface of the water.

The second phase of the trial began on September 30, 2013 and concluded on October 17, 2013. This phase addressed BP’s conduct related to stopping the release of hydrocarbons after April 22, 2010 and quantification of the amount of oil discharged. In light of BP’s criminal plea agreement with the DOJ acknowledging that it provided the government with false or misleading information throughout the spill response, we argued at trial that BP’s fraud delayed the final capping of the well and that we should not be liable for damages resulting from this delay. On December 20, 2013, the parties filed post-trial briefs and proposed findings of fact and conclusions of law, and on January 24, 2014, the parties filed response briefs. The MDL Court has not yet ruled on the issues tried in the second phase of the trial.

We can provide no assurances as to the outcome of the trial, as to the timing of any phase of trial or any rulings, that we will not enter into additional settlements as to some or all of the matters related to the Macondo well incident, including those to be determined at a trial, or the timing or terms of any such settlements.

Litigation—As of June 30, 2014, approximately 1,414 actions or claims were pending against us, along with other unaffiliated defendants, in state and federal courts. Additionally, government agencies have initiated investigations into the Macondo well incident. We have categorized below the nature of the legal actions or claims. We are evaluating all claims and intend to vigorously defend any claims and pursue any and all defenses available. In addition, we believe we are entitled to contractual defense and indemnity for all wrongful death and personal injury claims made by non-employees and third-party subcontractors’ employees as well as all liabilities for pollution or contamination, other than for pollution or contamination originating on or above the surface of the water. See “—Contractual indemnity.”

Wrongful death and personal injury—As of June 30, 2014, we have been named, along with other unaffiliated defendants, in nine complaints that were pending in state and federal courts in Louisiana and Texas involving multiple plaintiffs that allege wrongful death and other personal injuries arising out of the Macondo well incident. Nine complaints involve fatalities and 63 complaints seek recovery for bodily injuries. A number of these lawsuits have been settled. Per the order of the Multidistrict Litigation Panel (“MDL”), all claims but one have been centralized for discovery purposes in the MDL Court. The complaints generally allege negligence and seek awards of unspecified economic damages and punitive damages. BP, MI-SWACO, Weatherford International Ltd. and Cameron International Corporation (“Cameron”) and certain of their affiliates, have, based on contractual arrangements, also made indemnity demands upon us with respect to personal injury and wrongful death claims asserted by our employees or representatives of our employees against these entities. See “—Contractual indemnity.”

Economic loss—As of June 30, 2014, we and certain of our subsidiaries were named, along with other unaffiliated defendants, in 962 pending individual complaints as well as 199 putative class-action complaints that were pending in the federal and state courts in Louisiana, Texas, Mississippi, Alabama, Georgia, Kentucky, South Carolina, Tennessee, Florida and possibly other courts. The complaints generally allege, among other things, potential economic losses as a result of environmental pollution arising out of the Macondo well incident and are based primarily on the OPA and state OPA analogues. The plaintiffs are generally seeking awards of unspecified economic, compensatory and punitive damages, as well as injunctive relief. No classes have been certified at this time. Most of these actions have either been transferred to or are the subject of motions to transfer to the MDL. See “—Contractual indemnity.”

Cross-claims, counter-claims, and third-party claims—In April 2011, several defendants in the MDL litigation filed cross-claims or third-party claims against us and certain of our subsidiaries, and other defendants. BP filed a claim seeking contribution under the OPA and maritime law, subrogation and claimed breach of contract, unseaworthiness, negligence and gross negligence. Through these claims, BP sought to recover from us damages it has paid or may pay arising from the Macondo well incident. BP also sought a declaration that it is not liable in contribution, indemnification, or otherwise to us. Anadarko Petroleum Corporation (“Anadarko”), which owned a 25 percent non-operating interest in the Macondo well, asserted claims of negligence, gross negligence, and willful misconduct and is seeking indemnity under state and maritime law and contribution under maritime and state law as well as OPA. MOEX Offshore 2007 LLC (“MOEX”), which owns a 10 percent non-operating interest in the Macondo well, filed claims of negligence under state and maritime law, gross negligence under state law, gross negligence and willful misconduct under maritime law and is seeking indemnity under state and maritime law and contribution under maritime law and OPA. Cameron, the manufacturer and designer of the blowout preventer, asserted multiple claims for contractual indemnity and declarations regarding contractual obligations under various contracts and quotes and is also seeking non-contractual indemnity and contribution under maritime law and OPA. As part of the BP/PSC Settlement, one or more of these claims against us and certain of our subsidiaries have been assigned to the PSC settlement class. Halliburton Company (“Halliburton”), which provided cementing and mud-logging services to the operator, filed a claim against us seeking contribution and indemnity under maritime law, contractual indemnity and alleging negligence and gross negligence. Additionally, certain other third parties filed claims against us for indemnity and contribution.

In April 2011, we filed cross-claims and counter-claims against BP, Halliburton, Anadarko, MOEX, certain of these parties’ affiliates, the U.S. and certain other third parties. We seek indemnity, contribution, including contribution under OPA, and subrogation under OPA, and we have asserted claims for breach of warranty of workmanlike performance, strict liability for manufacturing and design defect, breach of express contract, and damages for the difference between the fair market value of Deepwater Horizon and the amount received from insurance proceeds. The Consent Decree limits our ability to seek indemnification or reimbursement with respect to certain of these matters against the owners of the Macondo well and dismissed our claims against the U.S. We are not pursuing arbitration on the key contractual issues with BP; instead, we are relying on the court to resolve the disputes.

Federal securities claims—On September 30, 2010, a federal securities proposed class action was filed in the U.S. District Court, Southern District of New York, naming us and former chief executive officers of Transocean Ltd. and one of our acquired companies as defendants. In the action, a former shareholder of the acquired company alleged that the joint proxy statement related to our shareholder meeting in connection with our merger with the acquired company violated Section 14(a) of the Securities Exchange Act of 1934 (the “Exchange Act”), Rule 14a-9 promulgated thereunder and Section 20(a) of the Exchange Act. The plaintiff claimed that the acquired company’s shareholders received inadequate consideration for their shares as a result of the alleged violations and sought compensatory and rescissory damages and attorneys’ fees on behalf of itself and the proposed class members. In connection with that action, we were obligated to pay the defense fees and costs for the individual defendants, which may be covered by our directors’ and officers’ liability insurance, subject to a deductible. On October 4, 2012, the court denied our motion to dismiss the action. On June 27, 2013, the U.S. Court of Appeals for the Second Circuit (the “Second Circuit”) ruled in the unrelated action on an issue that could be relevant to the disposition of this case in a manner that supported our position that the plaintiff’s existing claims alleged in the action are time-barred. On August 30, 2013, we filed a motion to dismiss on the ground that the claims are time-barred, citing the ruling of the Second Circuit. On September 20, 2013, plaintiffs filed an opposition to our motion to dismiss and on September 24, 2013, we filed a reply to that opposition. On March 11, 2014, the court granted the defendants’ motion and dismissed the claims as time-barred. On March 13, 2014, judgment was entered and the case was closed. On March 19, 2014, plaintiffs filed a notice of appeal to the Second Circuit. On April 23, 2014, the Second Circuit granted plaintiff’s motion to stay pending the U.S. Supreme Court’s decision in Public Employees Retirement System of Mississippi v. IndyMac MBS Inc., in which certiorari was granted at 134 S. Ct. 1515 (2014).

Other federal statutes—Several of the claimants have made assertions under the statutes, including the CWA, the Endangered Species Act, the Migratory Bird Treaty Act, the Clean Air Act, the CERCLA and the EPCRA.

Shareholder derivative claims—In June 2010, two shareholder derivative suits were filed in the state district court in Texas by our shareholders naming us as a nominal defendant and certain of our current and former officers and directors as defendants. These cases allege breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement and waste of corporate assets in connection with the Macondo well incident. The plaintiffs are generally seeking to recover, on behalf of us, damages to Transocean Ltd. and disgorgement of all profits, benefits, and other compensation from the individual defendants. Any recovery of the damages or disgorgement by the plaintiffs in these actions would be paid to us. If the plaintiffs prevail, we could be required to pay plaintiffs’ attorneys’ fees. In addition, we are obligated to pay the defense fees and costs for the individual defendants, which may be covered by our directors’ and officers’ liability insurance, subject to a deductible. The two actions have been consolidated before a single judge. In August 2012, the defendants filed a motion to dismiss the complaint on the grounds that the actions must be maintained in the courts of Switzerland and that the plaintiffs lack standing to assert the claims alleged. In December 2012, in response to defendants' motion to dismiss for lack of standing, the plaintiffs dismissed their action without prejudice. In January 2013, one of the plaintiffs re-filed a previously dismissed complaint seeking to recover damages to Transocean Ltd. and disgorgement of all profits, benefits, and other compensation from the individual defendants. Certain defendants filed a motion to dismiss the re-filed complaint in March 2013 on the ground that the action must be maintained in the courts of Switzerland. On July 30, 2013, the court granted the motion to dismiss. On August 29, 2013, the state district court of Texas dismissed the action in its entirety as to all defendants. Plaintiffs filed an appeal in the First Court of Appeals in Texas on September 6, 2013 and filed a brief in support of their appeal on November 27, 2013. On February 10, 2014, the defendants filed a response to the appeal, and on March 3, 2014, the plaintiffs filed a reply.

U.S. Department of Justice claims—On December 15, 2010, the DOJ filed a civil lawsuit against us and other unaffiliated defendants. The complaint alleged violations under OPA and the CWA, including claims for per barrel civil penalties of up to $1,100 per barrel or up to $4,300 per barrel if gross negligence or willful misconduct is established, and the DOJ reserved its rights to amend the complaint to add new claims and defendants. The U.S. government has estimated that up to 4.1 million barrels of oil were discharged and subject to penalties. The complaint asserted that all defendants named are jointly and severally liable for all removal costs and damages resulting from the Macondo well incident. In response to the U.S. complaint, BP and Anadarko filed claims seeking contribution from us for any damages for which they may be found liable, including OPA damages. On December 6, 2011, the DOJ filed a motion for partial summary judgment seeking a ruling that we were jointly and severally liable under OPA, and liable for civil penalties under the CWA, for all of the discharges from the Macondo well on the theory that discharges not only came from the well but also from the blowout preventer and riser, appurtenances of Deepwater Horizon.

On January 9, 2012, we filed our opposition to the motion and filed a cross-motion for partial summary judgment seeking a ruling that we are not liable for the subsurface discharge of hydrocarbons. On February 22, 2012, the MDL Court ruled that we are not liable as a responsible party for damages under OPA with respect to the below surface discharges from the Macondo well. The MDL Court did not rule on whether we could be liable for removal costs to the U.S. or any state or local government as an operator of the Macondo well. The court also ruled that the below surface discharge was discharged from the well facility, and not from the Deepwater Horizon vessel, within the meaning of the CWA, and that we, therefore, are not liable for such discharges as an owner of the vessel under the CWA. However, the MDL Court ruled that the issue of whether we could be held liable for such discharge under the CWA as an operator of the well facility could not be resolved on summary judgment. We subsequently entered into an agreement with the DOJ regarding liability to the U.S. with respect to its CWA claim through the Consent Decree. The Consent Decree did not resolve the rights of the U.S. with respect to certain liabilities under OPA for removal costs or resulting from NRDA. In August and September 2012, Anadarko and BP filed appeals to the Fifth Circuit, in which they argue that, under the CWA, the below-surface discharge was discharged from the vessel, not from the well facility. On June 4, 2014, the Fifth Circuit affirmed the ruling of the MDL Court that BP and Anadarko are liable for civil penalties under the CWA. The opinion did not address whether we could be considered the operator of the well for purposes of penalties under the CWA. As a result of our Consent Decree agreement, the outcome of this appeal does not affect our CWA civil penalty liability for the Macondo well incident. See “—Macondo well incident settlement obligations.”

In addition to the civil complaint, the DOJ served us with civil investigative demands on December 8, 2010. These demands were part of an investigation by the DOJ to determine if we made false claims, or false statements in support of claims, in violation of the False Claims Act, in connection with the operator’s acquisition of the leasehold interest in the Mississippi Canyon Block 252, Gulf of Mexico and drilling operations on Deepwater Horizon. As part of the settlement discussions, we inquired whether the U.S. intends to pursue any actions under the False Claims Act. In response, the DOJ sent us a letter stating that the Civil Division of the DOJ, based on facts then known, is no longer pursuing any investigation or claims, and did not have any present intention to pursue any investigation or claims, under the False Claims Act against the various Transocean entities for their involvement in the Macondo well incident.

As noted above, the DOJ also conducted a criminal investigation into the Macondo well incident. On March 7, 2011, the DOJ announced the formation of the Deepwater Horizon Task Force to lead the criminal investigation. The task force investigated possible violations by us and certain unaffiliated parties of the CWA, the Migratory Bird Treaty Act, the Refuse Act, the Endangered Species Act, and the Seaman’s Manslaughter Act, among other federal statutes, and possible criminal liabilities, including fines under those statutes and under the Alternative Fines Act. As discussed above, on January 3, 2013, we entered into the Plea Agreement with the DOJ resolving these claims. See “—Macondo well incident settlement obligations.”

State and other government claims—In June 2010, the Louisiana Department of Environmental Quality (the “LDEQ”) issued a consolidated compliance order and notice of potential penalty to us and certain of our subsidiaries asking us to eliminate and remediate discharges of oil and other pollutants into waters and property located in the State of Louisiana, and to submit a plan and report in response to the order. In October 2010, the LDEQ rescinded its enforcement actions against us and our subsidiaries but reserved its rights to seek civil penalties for future violations of the Louisiana Environmental Quality Act. In September 2010, the State of Louisiana filed an action for declaratory judgment seeking to designate us as a responsible party under OPA and the Louisiana Oil Spill Prevention and Response Act for the discharges emanating from the Macondo well.

Prior to the possible expiration of the statute of limitations in April 2013, suits were filed by over 200 state, local and foreign governments, including the U.S. States of Alabama, Florida, Louisiana, Mississippi and Texas; the Mexican States of Veracruz, Quintana Roo and Tamaulipas (“Mexican States”); the Federal Government of Mexico and by other local governments by and on behalf of multiple towns and parishes. These governments generally assert claims under OPA, other statutory environmental state claims and various common law claims. A local government master complaint also was filed in which cities, municipalities, and other local government entities can, and have, joined. Most of these new government cases, including the suits filed by the attorneys general of Alabama, Florida, Louisiana, Mississippi and Texas, have been transferred to the MDL.

The Mexican States’ OPA claims were subsequently dismissed for failure to demonstrate that recovery under OPA was authorized by treaty or executive agreement. However, the Court preserved some of the Mexican States’ negligence and gross negligence claims, but only to the extent there has been a physical injury to a proprietary interest. On September 6, 2013, the MDL Court ruled that the Federal Government of Mexico rather than the Mexican States had the proprietary interest in the property and natural resources allegedly injured by the spill and, on that basis, dismissed the remaining claims of the Mexican States. The Mexican States have appealed to the Fifth Circuit and briefing is scheduled to be completed as of July 28, 2014. Oral argument has not yet been scheduled. The claims of the Federal Government of Mexico remain pending. On September 18, 2013, the Mexican State of Yucatan filed a suit similar to those filed by the other Mexican States.

By letter dated May 5, 2010, the Attorneys General of the five Gulf Coast states of Alabama, Florida, Louisiana, Mississippi and Texas informed us that they intend to seek recovery of pollution cleanup costs and related damages arising from the Macondo well incident. In addition, by letter dated June 21, 2010, the Attorneys General of the 11 Atlantic Coast states of Connecticut, Delaware, Georgia, Maine, Maryland, Massachusetts, New Hampshire, New York, North Carolina, Rhode Island and South Carolina informed us that their states have not sustained any damage from the Macondo well incident but they would like assurances that we will be responsible financially if damages are sustained. We responded to each letter from the Attorneys General and indicated that we intend to fulfill our obligations as a responsible party for any discharge of oil from Deepwater Horizon on or above the surface of the water, and we assume that the operator will similarly fulfill its obligations under OPA for discharges from the undersea well.

On August 26, 2011, the MDL Court ruled on the motion to dismiss certain economic loss claims. The court ruled that state law, both statutory and common law, is inapplicable to the Macondo well incident. Accordingly, all claims brought under state law were dismissed. Secondly, general maritime law claims that do not allege physical damage to a proprietary interest were dismissed, unless the claim falls into the commercial fisherman exception. The court ruled that OPA claims for economic loss do not require physical damage to a proprietary interest. Third, the MDL Court ruled that presentment under OPA is a mandatory condition precedent to filing suit against a responsible party. Finally, the MDL Court ruled that claims for punitive damages may be available under general maritime law in claims against responsible parties and non-responsible parties. Certain Louisiana parishes appealed the dismissal of the state law penalty claims. On February 24, 2014, the Fifth Circuit affirmed the MDL Court’s dismissal of the state law claims. On May 28, 2014, the parishes filed a petition for writ of certiorari in the U.S. Supreme Court, and the U.S. Supreme Court has not yet acted on the petition.

The state, local and foreign government claims include claims under OPA. On February 22, 2012, the MDL Court ruled that we are not a responsible party under OPA for damages with respect to subsurface discharge from the Macondo well.

Prior to the possible expiration of the three-year statute of limitations on April 20, 2013, additional private plaintiffs filed new lawsuits relating to the Macondo well incident. We are named as a defendant in many but not all of the new lawsuits. The lawsuits seek recoveries for economic loss and punitive damages and allege claims under OPA, maritime law and state law. Some of the new lawsuits were filed in the MDL Court, but many were filed in state and federal courts outside of the MDL Court. Most of these cases have been transferred to the MDL and, consistent with our prior experience, we expect the remaining cases to be transferred to the MDL Court.

The MDL Court has begun proceeding with respect to Alabama’s compensatory damages claims under OPA and general maritime law. On January 14, 2014, the MDL Court ordered briefing on BP’s motion to strike Alabama’s demand for a jury trial. BP filed its motion on February 14, 2014. We and Halliburton filed briefs in support of the motion. Alabama opposed the motion and the other Gulf Coast states filed briefs in support of Alabama. BP filed its reply on March 25, 2014, and Transocean filed a reply memorandum on March 28, 2014. The MDL Court has not yet ruled on the motion. The MDL Court has set a schedule for pretrial discovery in the Alabama damages case. Fact discovery is scheduled to end on January 30, 2015, and expert discovery is scheduled to end on May 29, 2015. The MDL Court has not yet scheduled a trial date.

Natural Resources Damages Assessments—Under OPA, designated state and federal trustees are authorized to undertake a NRDA to assess potential natural resource injuries resulting from a discharge of oil or the substantial threat of a discharge and response activities and develop and implement a plan for restoration of injured resources, if any. The trustees will invite responsible parties to participate in and fund such efforts. As of June 30 , 2014, we have received 11 such requests as follows: (1) on September 27, 2010, from the U.S. Department of Commerce-National Oceanic and Atmospheric Association; (2) on October 14, 2010 from the U.S. Department of the Interior-Fish and Wildlife Service; (3) on November 19, 2010, from the Louisiana Department of Public Safety and Corrections-Public Safety Services; (4) on December 23, 2011, from the U.S. Department of the Interior-Fish and Wildlife Service; (5) on December 23, 2011, from the U.S. Department of Commerce-National Oceanic and Atmospheric Association; (6) on May 4, 2012, from the U.S. Department of Commerce-National Oceanic and Atmospheric Association; (7) on July 27, 2012, from the U.S. Department of Commerce-National Oceanic and Atmospheric Administration; (8) on September 19, 2012, from the U.S. Department of Commerce-National Oceanic and Atmospheric Administration; (9) on September 24, 2012, from the U.S. Department of Commerce-National Oceanic and Atmospheric Administration; (10) on October 4, 2012, from the U.S. Department of the Interior-Fish and Wildlife Service; and(11) on July 11, 2013, from the U.S. Department of Commerce-National Oceanic and Atmospheric Administration. We responded to these requests and declined to participate in the funding on the grounds that we are not a responsible party for discharges from the wellhead. The government is proceeding with the NRDA with funding provided by BP.

Citizen suits under environmental statutes—The Center for Biological Diversity (the “Center”), a private environmental group, sued BP, us and certain of our affiliates under multiple federal environmental statutes seeking monetary penalties and injunctive relief. The MDL Court dismissed all of the claims, and in January 2013, the Fifth Circuit affirmed that dismissal with one exception—the Fifth Circuit remanded to the district court the Center’s claim for injunctive relief (but not for penalties) based on BP and Transocean’s alleged failure to make certain reports about the constituents of oil spilled into the U.S. Gulf of Mexico as required by federal EPCRA.

On April 15, 2014, BP and we moved for summary judgment. On the same day, the Center moved for partial summary judgment against BP. It did not move for partial summary judgment against us, though it purported to reserve its right to do so in the future. Opposition briefs were filed on May 5, 2014, and reply briefs were filed on May 19, 2014. The Fifth Circuit has not yet scheduled a hearing date for oral argument or indicated when it will rule on the motions.

Wreck removal—By letter dated December 6, 2010, the U.S. Coast Guard requested us to formulate and submit a comprehensive oil removal plan to remove any diesel fuel contained in the sponsons and fuel tanks that can be recovered from Deepwater Horizon. We have conducted a survey of the rig wreckage and have confirmed that no diesel fuel remains on the rig. The U.S. Coast Guard has not requested that we remove the rig wreckage from the sea floor. In October 2012, a new sheen was reported and preliminarily determined to have originated from the Macondo well. We understand that BP was notified of the sheen in early September 2012 and had commenced an investigation to determine the source, whether the oil and mud were from the sea floor, the rig or rig equipment, or other sources. In February 2013, the U.S. Coast Guard submitted a request seeking analysis and recommendations as to the potential life of the rig’s riser and cofferdam resting on the seafloor and potential remediation or removal options. We have insurance coverage for wreck removal for up to 25 percent of Deepwater Horizon’s insured value, or $140 million, with any excess wreck removal liability generally covered to the extent of our remaining excess liability limits.

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. The first four excess layers have similar coverage and contractual terms, while the $250 million fifth layer is on a different policy form, which varies to some extent from the underlying coverage and contractual terms. Generally, we believe that the policy forms for all layers include coverage for personal injury and fatality claims of our crew and vendors, actual and compensatory damages, punitive damages and related legal defense costs and that the policy forms for the first four excess layers provide coverage for fines; however, we do not expect payments deemed to be criminal in nature to be covered by any of the layers.

In May 2010, we received notice from BP maintaining that it believes that it is entitled to additional insured status under our excess liability insurance program. Our insurers have also received notices from Anadarko and MOEX advising of their intent to preserve any rights they may have to our insurance policies as an additional insured under the drilling contract. In response, our wholly owned captive insurance subsidiary and our first four excess layer insurers filed declaratory judgment actions in the Houston Division of the U.S. District Court for the Southern District of Texas in May 2010 seeking a judgment declaring that they have limited additional insured obligations to BP, Anadarko and MOEX. We are parties to the declaratory judgment actions, which were transferred to the MDL Court for discovery and other purposes. On November 15, 2011, the MDL Court ruled that BP’s coverage rights are limited to the scope of our indemnification of BP in the drilling contract. A final judgment was entered against BP, Anadarko and MOEX, and BP appealed. On March 1, 2013, the Fifth Circuit Court of Appeals issued an opinion reversing the decision of the MDL Court, and holding that BP is an unrestricted additional insured under the policies issued by our wholly owned captive insurance company and the first four excess layer insurers. We and the insurers filed petitions for rehearing with the Fifth Circuit Court of Appeals. On August 29, 2013, the Fifth Circuit Court of Appeals issued an opinion withdrawing the March 1, 2013 opinion and certifying certain insurance law questions to the Texas Supreme Court. On September 6, 2013, the Texas Supreme Court accepted certification of these questions. The parties’ briefing to the Texas Supreme Court was completed on March 10, 2014. Oral argument has been scheduled for September 16, 2014.

We believe that additional insured coverage for BP, Anadarko or MOEX under the $250 million fifth layer of our insurance program is limited to the scope of our indemnification of BP under the drilling contract. While we cannot predict the outcome of the matter before the Texas Supreme Court or the outcome of any subsequent proceedings in the Fifth Circuit, we do not expect them to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

On June 17, 2011 and July 31, 2012, our first layer and second layer of excess insurers, respectively, each representing $150 million of insurance coverage, filed interpleader actions. On February 14, 2013, the third and fourth layers, each representing $200 million of insurance coverage, filed interpleader actions substantially similar to the prior filings. The insurers contend that they face multiple, and potentially competing, claims to the relevant insurance proceeds. In these actions, the insurers effectively ask the court to manage disbursement of the funds to the alleged claimants, as appropriate, and discharge the insurers of any additional liability. The parties to the first and second excess insurer interpleader actions have executed protocol agreements to facilitate the reimbursement and funding of settlements of personal injury and fatality claims of our crew and vendors (collectively, “crew claims”) using insurance funds and claims were submitted to the court for review. Following the court’s determination and approval of the amounts to be paid by the insurers with respect to the crew claims submitted by the parties to date, the first layer of excess insurers made reimbursement payments to the parties for crew claims during the year ended December 31, 2013. Parties to the third and fourth excess insurer interpleader actions have agreed to adjourn the deadline for responses to the pleadings to an unspecified date that will follow a decision in another action that pertains to our insurance.

Contractual indemnity—Under our drilling contract for Deepwater Horizon, the operator has agreed, among other things, to assume full responsibility for and defend, release and indemnify us from any loss, expense, claim, fine, penalty or liability for pollution or contamination, including control and removal thereof, arising out of or connected with operations under the contract other than for pollution or contamination originating on or above the surface of the water from hydrocarbons or other specified substances within the control and possession of the contractor, as to which we agreed to assume responsibility and protect, release and indemnify the operator. Although we do not believe it is applicable to the Macondo well incident, we also agreed to indemnify and defend the operator up to a limit of $15 million for claims for loss or damage to third parties arising from pollution caused by the rig while it is off the drilling location, while the rig is underway or during drive off or drift off of the rig from the drilling location. The operator has also agreed, among other things, (1) to defend, release and indemnify us against loss or damage to the reservoir, and loss of property rights to oil, gas and minerals below the surface of the earth and (2) to defend, release and indemnify us and bear the cost of bringing the well under control in the event of a blowout or other loss of control. We agreed to defend, release and indemnify the operator for personal injury and death of our employees, invitees and the employees of our subcontractors while the operator agreed to defend, release and indemnify us for personal injury and death of its employees, invitees and the employees of its other subcontractors, other than us. We have also agreed to defend, release and indemnify the operator for damages to the rig and equipment, including salvage or removal costs.

Although we believe we are entitled to contractual defense and indemnity, the operator has sought to avoid its indemnification obligations. In April 2011, the operator filed a claim seeking a declaration that it is not liable to us in contribution, indemnification, or otherwise. On November 1, 2011, we filed a motion for partial summary judgment, seeking enforcement of the indemnity obligations for pollution and civil fines and penalties contained in the drilling contract with the operator. On January 26, 2012, the court ruled that the drilling contract requires the operator to indemnify us for compensatory damages asserted by third parties against us related to pollution that did not originate on or above the surface of the water, even if the claim is the result of our strict liability, negligence, or gross negligence. The ruling is not currently subject to appeal, but may be appealed once a final judgment in the case is rendered. The court also held that the operator does not owe us indemnity to the extent that we are held liable for civil penalties under the CWA or for punitive damages, and we have since agreed with the DOJ that we will not seek indemnity or reimbursement of our Consent Decree payments from the operator or the other non-insurer defendants named in the complaint by the U.S. The court deferred ruling on the operator’s argument that we committed a core breach of the drilling contract or otherwise materially increased the operator’s risk or prejudiced its rights so as to vitiate the operator’s indemnity obligations. Our motion for partial summary judgment and the court’s ruling did not address the issue of contractual indemnity for criminal fines and penalties. The law generally considers contractual indemnity for criminal fines and penalties to be against public policy. Our motion did not ask the court to rule on the validity of BP’s agreement in the drilling contract to release us from any claims asserted by BP itself. Some courts have held that such agreements will not be enforced if the defendant is found to be grossly negligent. In May 2013, we filed a motion for partial summary judgment seeking to enforce BP’s agreement to release claims made by BP itself. The MDL Court has not yet ruled on this motion.

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 which claimed injuries arising out of exposure to asbestos allegedly contained in drilling mud during these plaintiffs’ employment in drilling activities between 1965 and 1986. The Circuit Courts subsequently dismissed the original 21 multi-plaintiff complaints and required each plaintiff to file a separate lawsuit. After certain individual claims were dismissed, 593 separate lawsuits remained, each with a single plaintiff. We have or may have direct or indirect interest in a total of 20 cases in Mississippi. The complaints generally allege that the defendants used or manufactured asbestos-containing drilling mud additives for use in connection with drilling operations and have included allegations of 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. In each of these cases, the complaints have named other unaffiliated defendant companies, including companies that allegedly manufactured the drilling-related products that contained asbestos. With the exception of cases pending in Jones and Jefferson counties, these cases are being governed for discovery and trial setting by a single Case Management Order entered by a Special Master appointed by the court to preside over the cases. Of the 20 cases in which we have or may have an interest, two have been scheduled for trial. During the year ended December 31, 2013, one of these two cases was resolved through a negotiated settlement for a nominal sum. In the other case, we were not named as a direct defendant, but the Special Master granted a Motion for Summary Judgment based on the absence of medical evidence in favor of all defendants. We have obtained a similar ruling on summary judgment dismissing three additional cases where we were a direct defendant. The resolution of these five cases leaves 15 remaining lawsuits in Mississippi in which we have or may have an interest.

In 2011, the Special Master issued a ruling that a Jones Act employer defendant, such as us, cannot be sued for punitive damages, and this ruling has now been obtained in three of our cases. To date, seven of the 593 cases have gone to trial against defendants who allegedly manufactured or distributed drilling mud additives. None of these cases has involved an individual Jones Act employer, and we have not been a defendant in any of these cases.

During the year ended December 31, 2013, a group of lawsuits premised on the same allegations as those in Mississippi were filed in Louisiana. Four of the original cases were dismissed through early motions. As of June 30, 2014, 20 plaintiffs have claims pending against one or more of our subsidiaries in four different lawsuits in Louisiana. We intend to defend these lawsuits vigorously, although we can provide no assurance as to the outcome. We historically have maintained broad liability insurance, although we are not certain whether insurance will cover the liabilities, if any, arising out of these claims. Based on our evaluation of the exposure to date, we do not expect the liability, if any, resulting from these claims to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

One of our subsidiaries was involved in lawsuits arising out of the subsidiary’s involvement in the design, construction and refurbishment of major industrial complexes. The operating assets of the subsidiary were sold and its operations discontinued in 1989, and the subsidiary has no remaining assets other than the insurance policies involved in its litigation, with its insurers and, either directly or indirectly through a qualified settlement fund. The subsidiary has been named as a defendant, along with numerous other companies, in lawsuits alleging bodily injury or personal injury as a result of exposure to asbestos. As of June 30, 2014, the subsidiary was a defendant in approximately 851 lawsuits, some of which include multiple plaintiffs, and we estimate that there are approximately 1,672 plaintiffs in these lawsuits. For many of these lawsuits, we have not been provided with sufficient information from the plaintiffs to determine whether all or some of the plaintiffs have claims against the subsidiary, the basis of any such claims, or the nature of their alleged injuries. The first of the asbestos-related lawsuits was filed against the subsidiary in 1990. Through June 30, 2014, the costs incurred to resolve claims, including both defense fees and expenses and settlement costs, have not been material, all known deductibles have been satisfied or are inapplicable, and the subsidiary’s defense fees and expenses and settlement costs have been met by insurance made available to the subsidiary. The subsidiary continues to be named as a defendant in additional lawsuits, and we cannot predict the number of additional cases in which it may be named a defendant nor can we predict the potential costs to resolve such additional cases or to resolve the pending cases. However, the subsidiary has in excess of $1.0 billion in insurance limits potentially available to the subsidiary. Although not all of the policies may be fully available due to the insolvency of certain insurers, we believe that the subsidiary will have sufficient funding directly or indirectly from settlements and claims 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 believe that the ultimate liability, if any, arising from these claims will have a material impact on our consolidated statement of financial position, results of operations or cash flows.

Rio de Janeiro tax assessment—In the third quarter of 2006, we received tax assessments of BRL 412 million, equivalent to approximately $186 million, including interest and penalties, from the state tax authorities of Rio de Janeiro in Brazil against one of our Brazilian subsidiaries for taxes on equipment imported into the state in connection with our operations. The assessments resulted from a preliminary finding by these authorities that our record keeping practices were deficient. We currently believe that the substantial majority of these assessments are without merit. We filed an initial response with the Rio de Janeiro tax authorities on September 9, 2006 refuting these additional tax assessments. In September 2007, we received confirmation from the state tax authorities that they believe the additional tax assessments are valid, and as a result, we filed an appeal on September 27, 2007 to the state Taxpayer’s Council contesting these 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 consolidated statement of financial position, results of operations or cash flows.

Brazilian import license assessment—In the fourth quarter of 2010, we received an assessment from the Brazilian federal tax authorities in Rio de Janeiro of BRL 541 million, equivalent to approximately $244 million, including interest and penalties, based upon the alleged failure to timely apply for import licenses for certain equipment and for allegedly providing improper information on import license applications. We believe that a substantial majority of the assessment is without merit and are vigorously pursuing legal remedies. The case was decided partially in favor of our Brazilian subsidiary in the lower administrative court level. The decision cancelled the majority of the assessment, reducing the total assessment to BRL 31 million, equivalent to approximately $14 million. On July 14, 2011, we filed an appeal to eliminate the assessment. On May 23, 2013, a ruling was issued that eliminated all assessment amounts. A further appeal by the taxing authorities is possible. While we cannot predict or provide assurance as to the outcome of these proceedings, we do not expect it to have a material adverse effect on our 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. The Federal High Court in Lagos has not yet ruled on the matter and has not scheduled a hearing. While we cannot predict or provide assurance as to the outcome of these proceedings, we do not expect it to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

Nigerian Industrial Training Fund litigation—Under the Nigerian Industrial Training Fund Act of 2004, as amended (the “Nigerian Act”), Nigerian companies with five or more employees must remit on an annual basis one percent of their payroll to the Industrial Training Fund (the “ITF”) established under the Nigerian Act to be used for the training of Nigerian nationals. We have not paid this amount on the cost of personnel movement to rigs or the expense of benefits to employees because the term “payroll” was not defined in the Nigerian Act at the relevant time, and we did not believe such costs should be considered “payroll” costs under the relevant legislation. The ITF brought suit against our now-liquidated subsidiary, Sedco Forex Nigeria Limited in the Lagos Federal High Court (the “Lagos Court”), and on October 28, 2013, the Lagos Court dismissed the lawsuit. In a related matter, the ITF brought suit against our wholly-owned subsidiary, Transocean Support Services Nigeria Limited (“TSSNL”). After the Lagos Court dismissed part of this lawsuit due to a lapse in the statute of limitations, the ITF filed a new action and sought to consolidate with the remainder of the first suit. In October 2013, the ITF also filed a criminal suit against TSSNL and Steven L. Newman, our chief executive officer, for allegedly failing to provide the required training to TSSNL’s employees, and on April 2, 2014, the Lagos Court dismissed the criminal suit. The Lagos Court has not yet issued a ruling on either the new action or the consolidated action against TSSNL, which are for amounts that are not material to our consolidated statement of financial position, results of operations or cash flows.

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

See Note 17—Subsequent Events.

Other environmental matters

Hazardous waste disposal sites—We have certain potential liabilities under 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 EPA and the DOJ to settle our potential liabilities for this site by agreeing to perform the remaining remediation required by the EPA. The form of the agreement is a consent decree, which has been entered by the court. 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. This site was formerly owned and operated by certain of our subsidiaries. It is presently owned by an unrelated party, which has received an order to test the property. We have also been advised that one or more of our subsidiaries is likely to be named by the EPA as a PRP for the San Gabriel Valley, Area 3, Superfund site, which includes this property. Testing has been completed at the property but no contaminants of concern were detected. 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.

On February 24, 2011, the Housing Authority of the City of Los Angeles (“HACLA”) filed an original complaint against multiple defendants for releases of hazardous substances and other hazardous materials based on prior use of a site it now owns between the late 1930s and 2008. HACLA seeks recovery for response costs and other damages resulting from the release of those hazardous substances and materials. On September 20, 2013, one of the third-party defendants filed claims against one of our subsidiaries as a fourth party defendant asserting cost recovery and contribution under CERCLA, contribution pursuant to California Health and Safety Code, equitable contribution and indemnity and declaratory judgment. Our subsidiary never owned or leased the site, and our subsidiary’s involvement at the site was primarily related to the demolition, excavation and grading of the site between 1979 and 1980. On May 23, 2014, our subsidiary and its insurer agreed to settle the matter with the third-party defendant, who in return will dismiss our subsidiary from the lawsuit.

Resolutions of other claims by the EPA, the involved state agency or PRPs are at various stages of investigation. These investigations involve determinations of:

§	the actual responsibility attributed to us and the other PRPs at the site;

§	appropriate investigatory or remedial actions; and

§	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:

§	the volume and nature of material, if any, contributed to the site for which we are responsible;

§	the number of other PRPs and their financial viability; and

§	the remediation methods and technology to be used.

It is difficult to quantify with certainty the potential cost of these environmental matters, particularly in respect of remediation obligations. Nevertheless, based upon the information currently available, we believe that our ultimate liability arising from all environmental matters, including the liability for all other related pending legal proceedings, asserted legal claims and known potential legal claims which are likely to be asserted, is adequately accrued and should not have a material effect on our consolidated statement of financial position or results of operations.

Retained risk

Overview—Our hull and machinery and excess liability insurance program is comprised of commercial market and captive insurance policies that we renew annually on May 1. We periodically evaluate our insurance limits and self-insured retentions. At June 30, 2014, the insured value of our drilling rig fleet was approximately $27.9 billion, excluding our rigs under construction.

We generally do not carry commercial market insurance coverage for loss of revenues, unless it is contractually required, or for losses resulting from physical damage to our fleet caused by named windstorms in the U.S. Gulf of Mexico, including liability for wreck removal costs.

Hull and machinery coverage—At June 30, 2014, under the hull and machinery program, we generally maintained a $125 million per occurrence deductible, limited to a maximum of $200 million per policy period. Subject to the same shared deductible, we also had coverage for an amount equal to 50 percent of a rig’s insured value for combined costs incurred to mitigate rig damage, wreck or debris removal and excess collision liability. Any excess wreck or debris removal costs and excess collision liability costs are generally covered to the extent of our remaining excess liability coverage.

Excess liability coverage—At June 30, 2014, we carried excess liability coverage of $700 million in the commercial market excluding deductibles and self-insured retention, noted below, which generally covers offshore risks such as personal injury, third-party property claims, and third-party non-crew claims, including wreck removal and pollution. Our excess liability coverage had (1) separate $10 million per occurrence deductibles on collision liability claims and (2) separate $5 million per occurrence deductibles on crew personal injury claims and on other third-party non-crew claims. Through our wholly owned captive insurance company, we retained the risk of the primary $50 million excess liability coverage. In addition, we generally retained the risk for any liability losses in excess of $750 million.

Other insurance coverage—At June 30, 2014, we also carried $100 million of additional insurance that generally covers expenses that would otherwise be assumed by the well owner, such as costs to control the well, redrill expenses and pollution from the well. This additional insurance provides coverage for such expenses in circumstances in which we have legal or contractual liability arising from our gross negligence or willful misconduct.

Letters of credit and surety bonds

At June 30, 2014 and December 31, 2013, we had outstanding letters of credit totaling $546 million and $575 million, respectively, issued under various committed and uncommitted credit lines provided by several banks to guarantee various contract bidding, performance activities and customs obligations, including letters of credit totaling $105 million and $104 million, respectively, that we agreed to maintain in support of the operations for Shelf Drilling (see Note 7—Discontinued Operations).

As is customary in the contract drilling business, we also have various surety bonds in place that secure customs obligations relating to the importation of our rigs and certain performance and other obligations. At June 30, 2014 and December 31, 2013, we had outstanding surety bonds totaling $6 million.

Note 14—Shareholders’ Equity

Distributions of qualifying additional paid-in capital—In May 2014, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $3.00 per outstanding share, payable in four quarterly installments of $0.75 per outstanding share, subject to certain limitations. We do not pay the distribution of qualifying additional paid-in capital with respect to our shares held in treasury or held by our subsidiary. In May 2014, we recognized a liability of $1.1 billion for the distribution payable, recorded in other current liabilities, with a corresponding entry to additional paid-in capital. On June 18, 2014, we paid the first installment in the aggregate amount of $272 million to shareholders of record as of May 30, 2014. At June 30, 2014, the aggregate carrying amount of the distribution payable was $816 million.

In May 2013, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $2.24 per outstanding share, payable in four quarterly installments of $0.56 per outstanding share, subject to certain limitations. We did not pay the distribution of qualifying additional paid-in capital with respect to our shares held in treasury or held by our subsidiary. In May 2013, we recognized a liability of $808 million for the distribution payable, recorded in other current liabilities, with a corresponding entry to additional paid-in capital. On March 19, 2014, we paid the final installment in the aggregate amount of $202 million to shareholders of record as of February 21, 2014. On June 19, 2013, we paid the initial installment in the aggregate amount of $202 million to shareholders of record as of May 31, 2013.

Shares held by subsidiary—One of our subsidiaries holds 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 June 30, 2014 and December 31, 2013, our subsidiary held 8.8 million shares and 10.2 million shares, respectively.

Note 15—Financial Instruments

The carrying amounts and fair values of our financial instruments were as follows (in millions):

	June 30, 2014				December 31, 2013
	Carrying amount		Fair value		Carrying amount		Fair value
Cash and cash equivalents	$	2,117	$	2,117	$	3,243	$	3,243

Long-term debt, including current maturities		10,457		11,682		10,702		11,784
Derivative instruments, assets		6		6		—		—

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

Cash and cash equivalents—The carrying amount of cash and cash equivalents represents the historical cost, plus accrued interest, which approximates fair value because of the short maturities of those instruments. We measured the estimated fair value of our cash equivalents using significant other observable inputs, representative of a Level 2 fair value measurement, including the net asset values of the investments. At June 30, 2014 and December 31, 2013, the aggregate carrying amount of our cash equivalents was $1.3 billion and $2.3 billion, respectively.

Notes and other loans receivable—We hold certain notes and other loans receivable, which originated in connection with certain asset dispositions and supplier advances. The carrying amount represents the amortized cost of our investments. We measured the estimated fair value using significant unobservable inputs, representative of a Level 3 fair value measurement, including the credit ratings of the borrowers. At June 30, 2014, the aggregate carrying amount of our notes receivable and other loans receivable was $15 million, recorded in other assets. At December 31, 2013, the aggregate carrying amount of our notes receivable and other loans receivable was $101 million, including $6 million and $95 million, recorded in other current assets and other assets, respectively.

Restricted cash investments—The carrying amount of the Eksportfinans Restricted Cash Investments represents the amortized cost of our investment. We measured the estimated fair value of the Eksportfinans Restricted Cash Investments using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads of the instruments. At June 30, 2014 and December 31, 2013, the aggregate carrying amount of the Eksportfinans Restricted Cash Investments was $517 million and $591 million, respectively. At June 30, 2014 and December 31, 2013, the estimated fair value of the Eksportfinans Restricted Cash Investments was $541 million and $619 million, respectively.

The carrying amount of the restricted cash investments for certain contingent obligations approximates fair value due to the short term nature of the instruments in which the restricted cash investments are held. At June 30, 2014 and December 31, 2013, the aggregate carrying amount of the restricted cash investments for certain contingent obligations was $9 million and $30 million, respectively.

Debt—We measured the estimated fair value of our fixed-rate debt using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments. At June 30, 2014 and December 31, 2013, the aggregate carrying amount of our fixed-rate debt was $10.5 billion. At June 30, 2014 and December 31, 2013, the aggregate estimated fair value of our fixed-rate debt was $11.7 billion and $11.6 billion, respectively.

The carrying amount of the variable-rate debt of our consolidated variable interest entities approximates fair value because the terms of those debt instruments include short-term interest rates and exclude penalties for prepayments. We measured the estimated fair value of the debt of our consolidated variable interest entities using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads of the instruments. At December 31, 2013, the aggregate carrying amount of the variable-rate debt of our consolidated variable interest entities was $163 million. In February 2014, we repaid the variable-rate debt of our consolidated variable interest entities.

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

Note 17—Subsequent Events

Norway tax investigations and trial—On July 2, 2014, the Norwegian district court in Oslo acquitted our three subsidiaries, two external tax attorneys and an external tax advisor of all criminal charges related to the disclosures in our Norwegian tax returns for the years 1999 through 2002 and statutory financial statements for the years ended December 31, 1996 through 2001. On July 16, 2014, the Norwegian authorities dropped the financial claim of NOK 1.8 billion, equivalent to approximately $300 million, against two of our subsidiaries, fully closing this matter, and on the same date, filed an appeal with respect to the following charges: (a) disclosures in our Norwegian tax returns related to a dividend payment in 2001, (b) disclosures in our Norwegian tax returns related to an intercompany rig sale in 1999 and (c) certain inaccuracies in Norwegian statutory financial statements for the years ended December 31, 1996 through 2001. We believe our Norwegian tax returns are materially correct as filed, and we intend to continue to vigorously contest any assertions to the contrary by the Norwegian civil and criminal authorities in connection with the various transactions being investigated. An unfavorable outcome on the Norwegian civil or criminal tax matters could result in a material adverse effect on our consolidated statement of financial position, results of operations or cash flows. See Note 6—Income Taxes—Tax returns—Norway tax investigations and trial.

Petrobras withholding taxes—In July 2014, we received letters from Petróleo Brasileiro S.A. (“Petrobras”) informing us that the Brazilian Federal Revenue Service (the “RFB”) is conducting a review to determine whether Petrobras correctly withheld income taxes from charter agreement remittances in 2008 and 2009 related to work performed by its contractors, including us. Petrobras indicated that, if it loses its ongoing appeals, it will seek to recover from its contractors, including us, any taxes, penalties, interest and fees that it is required to pay to the RFB as a result of the review. Petrobras has informed us that it has received from the RFB infraction notices related to work performed by us for BRL 283 million, equivalent to approximately $128 million, excluding penalties, interest and fees. We have informed Petrobras that we believe it has no basis for seeking reimbursement from us, and we intend to vigorously contest any assertions to the contrary. An unfavorable outcome on these matters could result in a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

Tax rate—In December 2013, the U.K. Treasury released draft proposals that would cap the amount a U.K.-based contractor would be able to claim as a deductible expense for charter payments made to related companies. A ring fence was also proposed to ensure that the profits from activities in relation to the chartering of rigs from affiliates are not reduced by tax relief from any unconnected activities. On July 17, 2014, the U.K. legislation received Royal Assent with retroactive application effective as of April 2014. As a result, we expect our effective tax rate on our worldwide earnings to increase beginning in the third quarter of 2014.

Transocean Partners LLC—On August 5, 2014, we completed an initial public offering to sell a noncontrolling interest in Transocean Partners LLC, a Marshall Islands limited liability company, which was formed on February 6, 2014, by Transocean Partners Holdings Limited, our wholly owned subsidiary, to own, operate and acquire modern, technologically advanced offshore drilling rigs.

Business

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

Our contract drilling services operations are geographically dispersed in oil and gas exploration and development areas throughout the world. Although rigs can be moved from one region to another, the cost of moving rigs and the availability of rig-moving vessels may cause the supply and demand balance to fluctuate somewhat between regions. Still, significant variations between regions do not tend to persist long term because of rig mobility. Our fleet operates in a single, global market for the provision of contract drilling services. The location of our rigs and the allocation of resources to build or upgrade rigs are determined by the activities and needs of our customers.

In February 2014, in connection with our efforts to discontinue non-strategic operations, we completed the sale of Applied Drilling Technology International Limited (“ADTI”), a U.K. company, which performs drilling management services in the North Sea. See Notes to Condensed Consolidated Financial Statements—Note 7—Discontinued Operations.

Significant Events

Norwegian tax investigations and trial—On July 2, 2014, the Norwegian authorities acquitted three of our subsidiaries of criminal charges relating to Norwegian tax returns filed for the years 1999 through 2002, as well as inaccuracies in Norwegian statutory financial statements for the years ended December 31, 1996 through 2001. See “—Contingencies—Tax matters.”

Transocean Partners, LLC—On August 5, 2014, we completed an initial public offering to sell a noncontrolling interest in Transocean Partners, a Marshall Islands limited liability company. See “—Outlook” and “—Liquidity and Capital Resources—Sources and uses of liquidity.”

Distributions of qualifying additional paid-in capital—In May 2014, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $3.00 per outstanding share, payable in four quarterly installments of $0.75 per outstanding share, subject to certain limitations. In May 2014, we recognized a liability of $1.1 billion for the distribution payable, recorded in other current liabilities, with a corresponding entry to additional paid-in capital. On June 18, 2014, we paid the first installment in the aggregate amount of $272 million to shareholders of record as of May 30, 2014.

See “—Liquidity and Capital Resources—Sources and uses of liquidity.”

Fleet expansion—In July 2014, we completed the construction of the Ultra-Deepwater drillship Deepwater Invictus, which commenced operations under its contract.

On February 26, 2014, we entered into agreements for the construction of two newbuild dynamically positioned Ultra-Deepwater drillships. We also entered into an options agreement to order up to three additional newbuild drillships with the same design and specifications. The first option must be exercised within one year, the second within 18 months and the final within 24 months.

See “—Liquidity and Capital Resources—Drilling fleet.”

Debt repayment—Angola Deepwater Drilling Company Limited (“ADDCL”), a consolidated joint venture company, had two credit facilities, established under a bank credit agreement (the “ADDCL Credit Facilities”). On February 12, 2014, we repaid borrowings of $163 million outstanding under the ADDCL Credit Facilities and terminated the bank credit agreement under which the credit facilities were established. See “—Liquidity and Capital Resources—Sources and uses of liquidity.”

Index

Discontinued operations—In February 2014, in connection with our efforts to discontinue non-strategic operations, we completed the sale of ADTI. In the six months ended June 30, 2014, we received net cash proceeds of $11 million and recognized a net loss of $12 million in connection with the sale. See “—Operating Results—Discontinued operations.”

Outlook

Drilling market—We expect the commodity pricing underlying the exploration and production programs of our customers to continue to support some contracting opportunities for all asset classes within our drilling fleet in the year ending December 31, 2014. However, based on customer and market indications, we expect the pace of executing drilling contracts for the global floater fleet to continue to be slow in the near term, resulting in excess capacity and idle time for some rigs. As of July 16, 2014, the contract backlog for our continuing operations was $25.0 billion compared to $26.1 billion as of April 17, 2014.

Following the Macondo well incident, the U.S. government implemented enhanced regulations related to offshore drilling in the U.S. Gulf of Mexico, which require operators to submit applications for new drilling permits that demonstrate compliance with such enhanced regulations. The enhanced regulations require independent third-party inspection, certification of well design and well control equipment and emergency response plans in the event of a blowout, among other requirements. The voluntary application by some of our customers of such third-party inspections and certifications of well control equipment operating outside the U.S. Gulf of Mexico has caused and may continue to cause us to experience additional out of service time and incur additional maintenance costs. We have entered into an agreement with the U.S. Department of Justice (“DOJ”) that also requires us to undertake certain inspections and certifications beyond current legal standards. Although the enhanced regulations and additional maintenance requirements have affected our revenues, costs and out of service time, we are unable to predict, with certainty, the magnitude with which these matters will continue to impact our operations.

Fleet status—As of July 16, 2014, uncommitted fleet rates for the remainder of 2014, 2015, 2016, 2017 and 2018 were as follows:

	2014		2015		2016		2017		2018
Uncommitted fleet rate (a)
High-Specification Floaters	27	%	48	%	65	%	73	%	83	%
Midwater Floaters	32	%	52	%	86	%	100	%	100	%
High-Specification Jackups	14	%	38	%	68	%	80	%	87	%

_____________________________

(a)

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.

As of July 16, 2014, we had 11 existing contracts associated with our continuing operations that had fixed-price or capped options to extend the contract terms that are exercisable, at the customer’s discretion, any time through their expiration dates. Customers are more likely to exercise fixed-price options when dayrates are higher on new contracts relative to existing contracts, and customers are less likely to exercise fixed-price options when dayrates are lower on new contracts relative to existing contracts. Given current market conditions, we are uncertain whether these options will be exercised by our customers in 2014. Additionally, well-in-progress or similar provisions of our existing contracts may delay the start of higher or lower dayrates in subsequent contracts, and some of the delays could be significant.

High-Specification Floaters—During the second quarter of 2014, 11 contracts for Ultra-Deepwater Floaters were entered into worldwide, including two new contracts for our fleet. Although the number of new contracts entered into worldwide was greater than the number of new contracts entered into in the first quarter, availability continues to exceed demand as customers turn their attention to capital discipline resulting in further delays for drilling programs and added pressure on utilization and dayrates in the second half of 2014 and into 2015. Our Ultra-Deepwater Floater fleet has 11 units with availability in 2014. The Deepwater Floater fleet rig utilization rate for the industry decreased during the second quarter of 2014 with five contracts entered into worldwide, including one new contract for our fleet. Our Deepwater Floater fleet has five active units with availability in 2014. The pace of tendering and length of contract terms have decreased, and we are experiencing increased competition for each tendering opportunity. As of July 16, 2014, we had 27 of our 46 High-Specification Floaters contracted through the end of 2014. Although we believe continued exploration successes in the major deepwater offshore provinces and the emerging markets will generate additional demand and support our long-term positive outlook for our High-Specification Floater fleet, we expect reduced dayrates, idling of rigs and increased competition for our floaters in the short term.

Midwater Floaters—Customer demand for our Midwater Floater fleet, which includes 21 semisubmersible rigs, has shown signs of weakness in the U.K. and Norway. We have three units available in our active fleet in 2014. The tendering pace has continued to be slow and demand has diminished outside of the U.K. and Norway, notably in Brazil, the Mediterranean and Southeast Asia, which has had a negative effect on global rig utilization rates and dayrates for this asset class in 2014.

High-Specification Jackups—We believe that market conditions will continue to support the high rig utilization rates and steady tendering and contracting activity through 2014. As of July 16, 2014, one of our existing 10 High-Specification Jackups have availability in 2014. Although total demand for High-Specification Jackups remains relatively stable year over year, we may experience some moderation in utilization and dayrates with the introduction of over 30 uncontracted newbuild High-Specification Jackups expected in 2015.

- 37 -

Index

Operating results—We expect our total revenues for the year ending December 31, 2014 to be in line with our total revenues for the year ended December 31, 2013, primarily due to a decrease in rig utilization for some of our floaters and the effect of asset divestitures, offset by additional revenues from partial years of operating dayrate for our two newbuild Ultra-Deepwater floaters placed into service or expected to be placed into service in the third quarter of 2014, full years of operating dayrate for our three newbuild High-Specification Jackups placed into service in the year ended December 31, 2013, higher revenue efficiency and higher contractual dayrates. We are unable to predict, with certainty, the impact on our business from any changes to offshore activity levels, the results of our efforts to improve our revenue efficiency rates or the full impact that the enhanced regulations and other matters, described under “—Drilling market”, will have on our operations for the year ending December 31, 2014 and beyond.

We expect our total operating and maintenance expenses for the year ending December 31, 2014 to be lower relative to our total operating and maintenance expenses for the year ended December 31, 2013, primarily due to a decrease in rig utilization for our Midwater Floater fleet and certain Deepwater and Ultra-Deepwater Floaters, a decrease in legal costs for ongoing Macondo well incident litigation, a decrease in shore-based costs and a decrease in operating costs as the result of optimization of rig-based spending and asset divestitures, partially offset by increased costs associated with higher out of service expenditures and partial years of operation for our newbuild Ultra-Deepwater Floaters placed into service or expected to be placed into service in the third quarter of 2014, full years of operations for our newbuild High-Specification Jackups placed into service in the year ended December 31, 2013, and normal inflationary trends for personnel, maintenance and other operating costs. Our projected operating and maintenance expenses for the year ending December 31, 2014 are subject to change and could be affected by actual activity levels, changes in shipyard timing, rig reactivations, the effective execution of our margin improvement efforts, the enhanced regulations and other matters described under “—Drilling market”, the Macondo well incident and related contingencies, exchange rates and cost inflation above expectations, as well as other factors.

Although we are unable to estimate the full direct and indirect effect that the Macondo well incident will have on our business, the incident has had and could continue to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows. See “—Contingencies—Macondo well incident.”

In accordance with our critical accounting policies, we review our property and equipment for impairment when events occur or circumstances change that may indicate that the carrying amounts of our assets held and used may not be recoverable. If we are unable to secure new or extended contracts for our active units or the reactivation of any of our stacked units, or if we experience increasingly unfavorable changes to actual or anticipated dayrates or other impairment indicators, we may be required to recognize losses in future periods as a result of impairments of the carrying amount of one or more of our asset groups. We may also be required to recognize losses on the impairment of one or more of our asset groups as a result of any significant changes in composition of our asset groups, which could occur as the result of certain potential transactions in the near future. At June 30, 2014, the carrying amount of our property and equipment, net of accumulated depreciation, was $22.4 billion, representing 70 percent of our total assets.

Additionally, we conduct impairment testing of our goodwill annually and when events occur or circumstances change that would more likely than not reduce the fair value of our reporting unit below its carrying amount. In the three months ended March 31, 2014, we identified indicators, such as the decline in the market value of our stock and the projected declines in dayrates and utilization, that the fair value of our goodwill could have fallen below its carrying amount, and as a result, we performed an interim goodwill impairment test. Although we concluded that our goodwill was not impaired as of March 31, 2014, we determined that our reporting unit was at risk of failing the first step of our goodwill impairment test, as the reporting unit’s estimated fair value exceeded its carrying amount by less than 10 percent. We did not identify any indicators of impairment in the three months ended June 30, 2014. If the market value of our stock declines or if we experience increasingly unfavorable changes to actual or anticipated market conditions, or to other impairment indicators, any of which may result in the fair value of our reporting unit falling below its carrying amount, we may be required to recognize losses on impairment of goodwill. At June 30, 2014, the carrying amount of our goodwill was $3.0 billion, representing nine percent of our total assets. See “-Critical Accounting Policies and Estimates” and “Item 1A. Risk Factors.”

Transocean Partners LLC—Transocean Partners LLC, a Marshall Islands limited liability company (“Transocean Partners”), was formed on February 6, 2014, by Transocean Partners Holdings Limited, our wholly owned subsidiary, to own, operate and acquire modern, technologically advanced offshore drilling rigs. The initial drilling units in the fleet include 51 percent ownership interest in the entities that own and operate the Ultra-Deepwater drillships Discoverer Inspiration and Discoverer Clear Leader and the Ultra-Deepwater semisubmersible Development Driller III, all of which are currently located in the U.S. Gulf of Mexico.

On July 31, 2014, Transocean Partners announced the pricing of its initial public offering of 17.5 million common units representing limited liability company interests at $22.00 per unit. The underwriters of the offering subsequently exercised in full their option to purchase up to an additional 2.6 million common units. The common units offered, including the common units purchased by the underwriters, represent a 29.2 percent limited liability company interest in Transocean Partners. Through Transocean Partners Holdings Limited, we own the remaining limited liability company interests in Transocean Partners. On July 31, 2014, the common units began trading on the New York Stock Exchange under the ticker symbol “RIGP”. On August 5, 2014, we completed the initial public offering.

U.K. North Sea Midwater Floaters—During the second half of the year ending December 31, 2014, we intend to pursue disposition of a group of rigs expected to consist primarily of approximately eight of our U.K. North Sea Midwater Floaters in connection with our efforts to reduce our exposure to low-specification drilling units.

Total	$	24,955	$	26,112	$	27,244

_____________________________

(a)

Contract backlog is defined as the maximum contractual operating dayrate multiplied by the number of days remaining in the firm contract period, excluding revenues for mobilization, demobilization and contract preparation or other incentive provisions, which are not expected to be significant to our contract drilling revenues.

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, which are excluded from the amounts presented for contract backlog.

Our contract backlog includes only firm commitments for our contract drilling services segment, which are represented by signed drilling contracts or, in some cases, by other definitive agreements awaiting contract execution. Our contract backlog includes amounts associated with our newbuild units that are currently under construction. The contractual operating dayrate may be higher than the actual dayrate we ultimately receive or an alternative contractual dayrate, such as a waiting-on-weather rate, repair rate, standby rate or force majeure rate, may apply under certain circumstances. The contractual operating dayrate may also be higher than the actual dayrate we ultimately receive because of a number of factors, including rig downtime or suspension of operations. In certain contracts, the dayrate may be reduced to zero if, for example, repairs extend beyond a stated period of time.

Average daily revenue—The average daily revenue for our contract drilling services segment was as follows:

	Three months ended
	June 30, 2014		March 31, 2014		June 30, 2013

Total fleet average daily revenue		410,000		413,100		382,800

_____________________________

(a)	Average daily revenue is defined as contract drilling revenues earned per operating day. An operating day is defined as a calendar day during which a rig is contracted to earn a dayrate during the firm contract period after commencement of operations.

Our average daily revenue fluctuates relative to market conditions and our revenue efficiency. Our total fleet average daily revenue is also affected by the mix of rig classes being operated, as Midwater Floaters and High-Specification Jackups are typically contracted at lower dayrates compared to High-Specification Floaters. We include newbuilds in the calculation when the rigs commence operations upon acceptance by the customer. We remove rigs from the calculation upon disposal, classification as held for sale or classification as discontinued operations.

_____________________________

(a)

Revenue efficiency is defined as actual contract drilling revenues for the measurement period divided by the maximum revenue calculated for the measurement period, expressed as a percentage. Maximum revenue is defined as the greatest amount of contract drilling revenues the drilling unit could earn for the measurement period, excluding amounts related to incentive provisions.

Our revenue efficiency rate varies due to revenues earned under alternative contractual dayrates, such as a waiting-on-weather rate, repair rate, standby rate, force majeure rate or zero rate, that may apply under certain circumstances. We include newbuilds in the calculation when the rigs commence operations upon acceptance by the customer. We exclude rigs that are not operating under contract, such as those that are stacked.

Rig utilization—The rig utilization rates for our contract drilling services segment were as follows:

	Three months ended

Total fleet average utilization		78	%		78	%		80	%

_____________________________

(a)	Rig utilization is defined as the total number of operating days divided by the total number of rig calendar days in the measurement period, expressed as a percentage.

Our rig utilization rate declines as a result of idle and stacked rigs and during shipyard and mobilization periods to the extent these rigs are not earning revenues. We include newbuilds in the calculation when the rigs commence operations upon acceptance by the customer. We remove rigs from the calculation upon disposal, classification as held for sale or classification as discontinued operations.

“n/m” means not meaningful.

Operating revenues—Contract drilling revenues decreased for the three months ended June 30, 2014 compared to the three months ended June 30, 2013 primarily due to the following: (a) approximately $105 million of decreased revenues due to lower rig utilization caused by greater time dedicated to mobilization between contracts, shipyard projects and rig certifications, (b) approximately $90 million of decreased revenues due to an increased number of idle rigs and (c) approximately $50 million of decreased revenues due to rigs sold or classified as held for sale, which were excluded from our rig utilization computation subsequent to June 30, 2013. These decreases were partially offset by the following: (a) approximately $105 million of increased revenues due to higher dayrates, (b) approximately $45 million of increased revenues due to improved revenue efficiency, (c) approximately $35 million of increased revenues related to the reactivation of the Midwater Floater Sedco 712 and (d) approximately $20 million of increased revenues associated with our newbuild High-Specification Jackups that commenced operations in the year ended December 31, 2013.

Other revenues increased for the three months ended June 30, 2014 compared to the three months ended June 30, 2013, primarily due to increased recognition of revenues associated with reimbursable items.

Costs and expenses—Operating and maintenance expense decreased for the three months ended June 30, 2014 compared to the three months ended June 30, 2013 primarily due to the following: (a) approximately $50 million of decreased costs and expenses incurred during mobilization between contracts, shipyard projects and rig certifications, (b) approximately $45 million of decreased costs and expenses associated with stacked and idle rigs, (c) approximately $25 million of decreased costs and expenses due to rigs sold or classified as held for sale subsequent to June 30, 2013 and (d) approximately $15 million of decreased costs and expenses associated with the Macondo well incident. These decreases were partially offset by approximately $10 million of increased costs and expenses associated with our newbuild High-Specification Jackups that commenced operations in the year ended December 31, 2013.

General and administrative expense decreased for the three months ended June 30, 2014 compared to the three months ended June 30, 2013 primarily due to the following: (a) a decrease of $7 million associated with legal and professional fees, primarily related to litigation and the 2013 proxy campaign, and (b) a decrease of $4 million associated with reduced wages and salaries.

Index

In the three months ended June 30, 2013, we recognized an aggregate loss of $37 million associated with the impairment of the Deepwater Floater Sedco 709 and the Midwater Floaters C. Kirk Rhein, Jr. and Sedco 703, all of which were classified as assets held for sale at the time of impairment.

Other income and expense—Interest expense, net of amounts capitalized, decreased in the three months ended June 30, 2014 compared to the three months ended June 30, 2013, primarily due to $26 million of increased capitalized interest associated with our newbuild construction program and $5 million of decreased interest expense associated with debt repaid or repurchased subsequent to the three months ended June 30, 2013.

In the three months ended June 30, 2014, we recognized other income, net primarily due to the following: (a) a gain of $7 million associated with the prepayment of Awilco Drilling plc (“Awilco”) notes receivable and (b) a gain of $7 million associated with settlement of litigation related to our dual-activity patent, partially offset by (c) a loss of $4 million associated with the early termination of our $900 million three year secured revolving credit facility. In the three months ended June 30, 2013, we recognized other expense, net primarily due to the following: (a) a loss of $10 million associated with the sale of the Shelf Drilling preference shares, (b) a loss of $9 million associated with the termination of the interest rate swaps related to the TPDI Credit Facilities and (c) a loss of $1 million associated with the early termination of the TPDI Credit Facilities

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. At June 30, 2014 and 2013, the annual effective tax rates were 12.6 percent and 23.8 percent, respectively, based on income from continuing operations before income taxes, after excluding certain items, such as losses on impairment, and gains and losses on certain asset disposals. The tax effect, if any, of the excluded items as well as settlements of prior year tax liabilities and changes in prior year tax estimates are all treated as discrete period tax expenses or benefits. For the three months ended June 30, 2014 and 2013, the effect of the various discrete period tax items was a net tax benefit of $14 million and net tax expense of $11 million, respectively. For the three months ended June 30, 2014 and 2013, these discrete tax items, coupled with the excluded income and expense items noted above, resulted in effective tax rates of 10.7 percent and 29.1 percent, respectively, based on income from continuing operations before income taxes.

The relationship between our provision for or benefit from income taxes and our income before income taxes can vary significantly from period to period considering, among other factors, (a) the overall level of income before income taxes, (b) changes in the 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 annual marginal tax rate is lower than our annual effective tax rate. Consequently, our income tax expense does not change proportionally with our income before income taxes. 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 annual effective tax rate calculation for the three months ended June 30, 2014, a significant portion of our income tax expense was generated in countries in which income taxes are imposed on gross revenues, with the most significant of these countries being Angola, India, Nigeria, Indonesia, and the Republic of Congo. Conversely, the most significant countries in which we operated during this period that impose income taxes based on income before income tax include Norway, the U.K., Switzerland, Australia and the U.S.

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

Discontinued operations

Overview—We have discontinued the operations of (a) the standard jackup and swamp barge contract drilling services and (b) the drilling management services operating segment.

A summary of the results of our discontinued operations, before income taxes, was as follows:

		Three months ended June 30,					Six months ended June 30,
		2014			2013		2014			2013
		(in millions)					(In millions)
Gain (loss) on disposal of assets in discontinued operations, net	$	—		$	3		$	(10	)	$	18
Other income (loss) from operations of discontinued operations		(2	)		(7	)		2			(19	)

In the three and six months ended June 30, 2014, other income from operations of discontinued operations was negligible, primarily as the result of the operations of standard jackups under operating agreements with Shelf Drilling. In the three and six months ended June 30, 2013, included in other loss from operations of discontinued operations, were losses of $4 million and $11 million, respectively, associated with the discontinued operations of the standard jackups under operating agreements with Shelf Drilling. In the three and six months ended June 30, 2013, included in other loss from operations of discontinued operations, were losses of $3 million and $8 million, respectively, associated with the drilling management services operating segment. Net gains or losses on disposal of assets in discontinued operations are discussed below.

Standard jackup and swamp barge contract drilling services—In September 2012, in connection with our efforts to dispose of non-strategic assets and to reduce our exposure to low-specification drilling units, we committed to a plan to discontinue operations associated with the standard jackup and swamp barge asset groups. In November 2012, we completed the sale of 38 drilling units to Shelf Drilling.

For a transition period following the completion of the sale transactions, we agreed to continue to operate a substantial portion of the standard jackups under operating agreements with Shelf Drilling and to provide certain other transition services to Shelf Drilling. Under the operating agreements, we agreed to remit the collections from our customers under the associated drilling contracts to Shelf Drilling, and Shelf Drilling has agreed to reimburse us for our direct costs and expenses incurred while operating the standard jackups on behalf of Shelf Drilling with certain exceptions. The costs to us for providing such operating and transition services, including allocated indirect costs, have exceeded the amounts we have received from Shelf Drilling for providing such services. As of July 29, 2014, we operated two standard jackups under operating agreements with Shelf Drilling, and we expect to complete performing services under such operating agreements before December 31, 2014.

In the three and six months ended June 30, 2014, we recognized net gains of $1 million and $2 million, respectively, associated with the disposal of assets unrelated to rig sales. In the three and six months ended June 30, 2013, we recognized a net gain of $3 million associated with the disposal of assets unrelated to rig sales.

In the six months ended June 30, 2013, we recognized an aggregate net gain of $15 million associated with the disposal of the Standard Jackups D.R. Stewart, GSF Adriatic VIII and Interocean III and related equipment.

Drilling management services—In February 2014, in connection with our efforts to discontinue non-strategic operations, we completed the sale of ADTI, which performs drilling management services in the North Sea. Following the completion of the sale transaction, we agreed to provide a $15 million working capital line of credit to the buyer through March 2016. We also provide a limited guarantee in favor of one customer through completion of the current drilling project, which is expected to occur in the fourth quarter of 2014. In the six months ended June 30, 2014, we received net cash proceeds of $11 million associated with the sale of the drilling management services business. In the three and six months ended June 30, 2014, we recognized a net loss of $1 million and $12 million, respectively.

See Notes to Condensed Consolidated Financial Statements—Note 7—Discontinued Operations.

Liquidity and Capital Resources

Sources and uses of cash

At June 30, 2014, we had $2.1 billion in cash and cash equivalents. At any given time, we may require a significant portion of our cash and cash equivalents for working capital and other needs related to the operation of our business. At June 30, 2014, we estimate the amount of cash required for these purposes, which is not generally available to us for other uses, was approximately $1.3 billion.

For the six months ended June 30, 2014, our primary sources of cash were our cash flows from operating activities, proceeds from restricted cash investments, net, and proceeds from asset disposals. Our primary uses of cash were capital expenditures, primarily associated with our newbuild projects, and cash used to pay to our shareholders installments of distributions of qualifying paid-in capital.

Net cash used in investing activities increased primarily due to the following: (a) an increase in capital expenditures, primarily associated with milestone payments for our major construction projects and other shipyard projects, and (b) a reduction of proceeds from investments in debt and equity instruments, as cash proceeds from prepayments of the Awilco notes in the six months ended June 30, 2014 were less than cash proceeds from the sale of Shelf Drilling preference shares in the six months ended June 30, 2013.

Net cash used in financing activities decreased primarily due to a reduction in cash used to repay debt during the six months ended June 30, 2014 compared to the six months ended June 30, 2013. Partially offsetting the decrease was an increase in cash used to pay to our shareholders installments of distributions of qualifying paid-in capital.

Drilling fleet

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

As of June 30, 2014, we held options to order up to five Keppel FELS Super B 400 Bigfoot class design High-Specification Jackups, the first of which must be exercised by November 2014 and the remaining four options must be exercised within consecutive four-month intervals thereafter. We also held options with Jurong Shipyard PTE Ltd. in Singapore to order up to three newbuild Ultra-Deepwater drillships, the first of which must be exercised by February 2015, the second by August 2015 and the final by February 2016.

In the six months ended June 30, 2014, we made capital expenditures of $1.5 billion, including capitalized interest of $76 million. The following table presents the historical and projected capital expenditures and capitalized interest, for our ongoing major construction projects:

_____________________________

(a)

The Ultra-Deepwater drillship Deepwater Invictus commenced operations in July 2014. The Ultra-Deepwater drillship Deepwater Asgard is expected to commence operations in the third quarter of 2014. The total carrying amount included capitalized costs of $272 million, representing the estimated fair value of construction in progress acquired in connection with our acquisition of Aker Drilling ASA in October 2011.

(b)

(c)	Deepwater Conqueror, a newbuild Ultra-Deepwater drillship under construction at the Daewoo Shipbuilding & Marine Engineering Co. Ltd. shipyard in Korea, is expected to commence operations in the fourth quarter of 2016.

(d)

(e)	Our two unnamed dynamically positioned Ultra-Deepwater drillships under construction at the Jurong Shipyard PTE Ltd. in Singapore do not yet have drilling contracts and are expected to be delivered in the second quarter of 2017 and the first quarter of 2018, respectively.

For the full year ending December 31, 2014, we expect total capital expenditures to be approximately $2.5 billion, approximately $1.6 billion of which is associated with our major construction projects. 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 new 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.

Index

We intend to fund the cash requirements relating to our capital expenditures through available cash balances, cash generated from operations and asset sales. We also have available credit under the New Five-Year Revolving Credit Facility, as described below, and may utilize other commercial bank or capital market financings. Economic conditions could impact the availability of these sources of funding.

Dispositions—From time to time, we may also review the possible disposition of non-strategic drilling units. During the six months ended June 30, 2014, we completed the sale of the High-Specification Jackup GSF Monitor along with related equipment. In the six months ended June 30, 2014, in connection with the disposal of GSF Monitor and related equipment, we received net cash proceeds of $83 million.

Sources and uses of liquidity

Overview—We expect to use existing cash balances, internally generated cash flows, borrowings under bank credit agreements and proceeds from the disposal of assets or proceeds from the sale of a noncontrolling interest in Transocean Partners to fulfill anticipated obligations, such as scheduled debt maturities or other payments, repayment of debt due within one year, capital expenditures, shareholder-approved distributions, payments of our Macondo well incident settlement obligations, working capital and other needs in our operations. Subject in each case to then existing market conditions and to our then expected liquidity needs, among other factors, we may continue to use a portion of our internally generated cash flows and proceeds from asset sales or proceeds from the sale of a noncontrolling interest in Transocean Partners to reduce debt prior to scheduled maturities through debt repurchases, either in the open market or in privately negotiated transactions, through debt redemptions or tender offers, or through repayments of bank borrowings.

At any given time, we may require a significant portion of our cash on hand for working capital and other needs related to the operation of our business. We currently estimate this amount to be approximately $1.3 billion. As a result, this portion of cash is not generally available to us for other uses. From time to time, we may also use borrowings under bank credit agreements to maintain liquidity for short-term cash needs.

On January 3, 2013, we reached an agreement with the DOJ to resolve certain outstanding civil and potential criminal charges against us arising from the Macondo well incident (see “—Plea Agreement obligations” and “—Consent Decree obligations”). However, we are unable to predict the ultimate outcome of the investigations of the Macondo well incident and the DOJ lawsuits and other litigation related to other claims that were not addressed in our resolution with the DOJ. We can give no assurance that the matters arising out of the Macondo well incident will not adversely affect our liquidity in the future.

Our access to debt and equity markets may be limited due to a variety of events, including, among others, credit rating agency downgrades of our debt ratings, potential liability related to the Macondo well incident, industry conditions, general economic conditions, market conditions and market perceptions of us and our industry. Uncertainty related to our potential liabilities from the Macondo well incident has had, and could continue to have, an adverse effect on our business and our financial condition. Our ability to access such markets may be severely restricted at a time when we would like, or need, to access such markets, which could have an impact on our flexibility to react to changing economic and business conditions. An economic downturn could have an impact on the lenders participating in our credit facilities or on our customers, causing them to fail to meet their obligations to us. Uncertainty related to our potential liabilities from the Macondo well incident has had an adverse effect on our share price and could impact our ability to access capital markets in the future.

Our internally generated cash flow is directly related to our business and the market sectors in which we operate. Should the drilling market deteriorate, or should we experience poor results in our operations, cash flow from operations may be reduced. We have, however, continued to generate positive cash flow from operating activities over recent years and expect that such cash flow will continue to be positive over the next year.

Distributions of qualifying additional paid-in capital—In May 2014, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $3.00 per outstanding share, payable in four quarterly installments, subject to certain limitations. We do not pay the distribution of qualifying additional paid-in capital with respect to our shares held in treasury or held by our subsidiary. In May 2014, we recognized a liability of $1.1 billion for the distribution payable, recorded in other current liabilities, with a corresponding entry to additional paid-in capital. On June 18, 2014, we paid the first installment of $272 million to shareholders of record as of May 30, 2014. At June 30, 2014, the carrying amount of the unpaid distribution payable was $816 million, which we expect to pay in three installments in September 2014, December 2014 and March 2015.

In May 2013, at our annual general meeting, our shareholders approved the distribution of qualifying additional paid-in capital in the form of a U.S. dollar denominated dividend of $2.24 per outstanding share, payable in four quarterly installments, subject to certain limitations. We did not pay the distribution of qualifying additional paid-in capital with respect to our shares held in treasury or held by our subsidiary. In May 2013, we recognized a liability of $808 million for the distribution payable, recorded in other current liabilities, with a corresponding entry to additional paid-in capital. On June 19, 2013, we made the initial installment of $202 million to shareholders of record as of May 31, 2013. On March 19, 2014, we made the final installment of $202 million to shareholders of record as of February 21, 2014.

Primary Revolving Credit Facilities—In June 2014, we entered into an amended and restated bank credit agreement, which established a $3.0 billion unsecured five-year revolving credit facility, that is scheduled to expire on June 28, 2019 (the “New Five-Year Revolving Credit Facility”). Among other things, the New 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 New Five-Year Revolving Credit Facility also includes a covenant imposing a maximum debt to tangible capitalization ratio of 0.6 to 1.0. As of June 30, 2014, our debt to tangible capitalization ratio, as defined, was 0.4 to 1.0. In order to borrow or have letters of credit issued under the New Five-Year Revolving Credit Facility, we must, at the time of the borrowing request, not be in default under the bank credit agreements and make certain representations and warranties, including with respect to compliance with laws and solvency, to the lenders, but we are not required to make any representation to the lenders as to the absence of a material adverse effect. Repayment of borrowings under the New Five-Year Revolving Credit Facility is subject to acceleration upon the occurrence of an event of default. We are also subject to various covenants under the indentures pursuant to which our public debt was issued, including restrictions on creating liens, engaging in sale/leaseback transactions and engaging in certain merger, consolidation or reorganization transactions. A default under our public debt indentures, our bank credit agreements, our capital lease contract or any other debt owed to unaffiliated entities that exceeds $125 million could trigger a default under the New Five-Year Revolving Credit Facility and, if not waived by the lenders, could cause us to lose access to the New Five-Year Revolving Credit Facility.

We may borrow under the New Five-Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate (“LIBOR”) plus a margin (the “New Five-Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the credit rating of our non-credit enhanced senior unsecured long-term debt (“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 New 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 depending on our Debt Rating. At June 30, 2014, based on our Debt Rating on that date, the New Five-Year Revolving Credit Facility Margin was 1.5 percent and the facility fee was 0.225 percent. At July 29, 2014, we had no borrowings outstanding, we had $20 million in letters of credit issued, and we had $3.0 billion of available borrowing capacity under the New Five-Year Revolving Credit Facility.

We had a $2.0 billion five-year revolving credit facility, established under a bank credit agreement dated November 1, 2011, as amended, that was scheduled to expire on November 1, 2016 (the “Former Five-Year Revolving Credit Facility”). We also had a $900 million three-year secured revolving credit facility, established under a bank credit agreement dated October 25, 2012, that was scheduled to expire on October 25, 2015 (the “Former Three-Year Secured Revolving Credit Facility” and, together with the Former Five-Year Revolving Credit Facility, the “Former Revolving Credit Facilities”). Borrowings under the Former Three-Year Secured Revolving Credit Facility were secured by the Ultra-Deepwater Floaters Deepwater Champion, Discoverer Americas and Discoverer Inspiration and were guaranteed by Transocean Ltd. and Transocean Inc. In June 2014, we terminated the Former Three-Year Revolving Credit Facility and the related security agreements, and the New Five-Year Revolving Credit Facility replaced the Former Five-Year Revolving Credit Facility. At the time of their termination or replacement, no borrowings were outstanding under the Former Revolving Credit Facilities.

Eksportfinans Loans—We have outstanding borrowings under the Loan Agreement dated September 12, 2008 (“Eksportfinans Loan A”) and outstanding borrowings under the Loan Agreement dated November 18, 2008 (“Eksportfinans Loan B,” and together with Eksportfinans Loan A, the “Eksportfinans Loans”), which were established to finance the construction and delivery of the Harsh Environment Ultra-Deepwater semisubmersibles Transocean Spitsbergen and Transocean Barents. Eksportfinans Loan A and Eksportfinans Loan B bear interest at a fixed rate of 4.15 percent and require semi-annual installments of principal and interest through September 2017 and January 2018, respectively. At July 29, 2014, borrowings of $242 million were outstanding under each of Eksportfinans Loan A and Eksportfinans Loan B.

The Eksportfinans Loans require restricted cash investments to be held by a certain financial institution through expiration (the “Eksportfinans Restricted Cash Investments”). The Eksportfinans Restricted Cash Investments bear interest at a fixed rate of 4.15 percent with semi-annual installments that correspond with those of the Eksportfinans Loans. At July 29, 2014, the aggregate balance of the Eksportfinans Restricted Cash Investments was $484 million.

Debt repayments—ADDCL had two credit facilities, established under the ADDCL Credit Facilities. On February 12, 2014, we repaid borrowings of $163 million outstanding under the ADDCL Credit Facilities and terminated the bank credit agreement under which the credit facilities were established.

Capital lease contract—Petrobras 10000 is held by one of our subsidiaries under a capital lease contract that requires scheduled monthly payments of $6 million through its stated maturity on August 4, 2029, at which time our subsidiary will have the right and obligation to acquire Petrobras 10000 from the lessor for one dollar. Upon the occurrence of certain termination events, our subsidiary is also required to purchase Petrobras 10000 and pay a termination amount determined by a formula based upon the total cost of the drillship. The capital lease contract includes limitations on creating liens on Petrobras 10000 and requires our subsidiary to make certain representations in connection with each monthly payment, including with respect to the absence of pending or threatened litigation or other proceedings against our subsidiary or any of its affiliates, which, if determined adversely, could have a material adverse effect on our subsidiary’s ability to perform its obligations under the capital lease contract. Additionally, Transocean Inc. has guaranteed the obligations under the capital lease contract, and Transocean Inc. is required to maintain an adjusted net worth, as defined, of at least $5.0 billion as of the end of each fiscal quarter. In the event Transocean Inc. does not satisfy this covenant at the end of any fiscal quarter, it is required to deposit the deficit amount, determined as the difference between $5.0 billion and the adjusted net worth for such fiscal quarter, into an escrow account for the benefit of the lessor. At July 29, 2014, $626 million was outstanding under the capital lease contract.

Plea Agreement obligations—Pursuant to a cooperation guilty plea agreement by and among the DOJ and certain of our affiliates (the “Plea Agreement”), which was accepted by the court on February 14, 2013, we agreed to pay a criminal fine of $100 million and to consent to the entry of an order requiring us to pay a total of $150 million to the National Fish & Wildlife Foundation, and $150 million to the National Academy of Sciences. In the six months ended June 30, 2014, we made an aggregate cash payment of $60 million. At July 29, 2014, the remaining balance of our Plea Agreement obligations was $180 million, payable as follows: (a) $39 million payable to the National Fish and Wildlife Foundation, which is due on or before February 13, 2015 and (b) $141 million payable to the National Academy of Sciences, $21 million of which is due on or before February 13, 2015, $60 million of which is due on or before February 12, 2016 and $60 million of which is due on or before February 14, 2017.

Consent Decree obligations—Pursuant to a civil consent decree by and among the DOJ and certain of our affiliates (the “Consent Decree”), which was approved by the court on February 19, 2013, we agreed to pay a civil penalty totaling $1.0 billion, plus interest at a fixed rate of 2.15 percent. In the six months ended June 30, 2014, we paid $412 million, including interest. At July 29, 2014, the remaining balance of our Consent Decree obligations was $200 million, excluding accrued interest, payable on or before February 19, 2015.

Notes receivable—We held two notes receivable from Awilco, a U.K. company listed on the Oslo Stock Exchange. The notes receivable were originally accepted in exchange for, and were secured by, two drilling units. In April 2014, Awilco repaid the notes, and we received cash proceeds of $98 million as prepayment of the aggregate principal outstanding.

Share repurchase program—In May 2009, at our annual general meeting, our shareholders approved and authorized our board of directors, at its discretion, to repurchase an amount of our shares for cancellation with an aggregate purchase price of up to CHF 3.5 billion, which is equivalent to approximately $3.8 billion at an exchange rate as of the close of trading on July 29, 2014 of $1.00 to CHF 0.91. On February 12, 2010, our board of directors authorized our management to implement the share repurchase program. We intend to fund any repurchases using available cash balances and cash from operating activities. On May 24, 2013, we received approval from the Swiss authorities for the continuation of the share repurchase program for a further three-year repurchase period through May 23, 2016. In the six months ended June 30, 2014, we did not purchase shares under our share repurchase program.

We may decide, based upon our ongoing capital requirements, our program of distributions to our shareholders, the price of our shares, matters relating to the Macondo well incident, regulatory and tax considerations, cash flow generation, the amount and duration of our contract backlog, general market conditions, debt ratings considerations and other factors, that we should retain cash, reduce debt, make capital investments or acquisitions or otherwise use cash for general corporate purposes, and consequently, repurchase fewer or no additional shares under this program. Decisions regarding the amount, if any, and timing of any share repurchases will be made from time to time based upon these factors.

Any shares repurchased under this program are expected to be purchased from time to time either, with respect to the U.S. market, from market participants that have acquired those shares on the open market and that can fully recover Swiss withholding tax resulting from the share repurchase or, with respect to the Swiss market, on the second trading line for our shares on the SIX. Repurchases could also be made by tender offer, in privately negotiated transactions or by any other share repurchase method. Any repurchased shares would be held by us for cancellation by the shareholders at a future annual general meeting. The share repurchase program could be suspended or discontinued by our board of directors or company management, as applicable, at any time.

Under Swiss corporate law, the right of a company and its subsidiaries to repurchase and hold its own shares is limited. A company may repurchase its shares to the extent it has freely distributable reserves as shown on its Swiss statutory balance sheet in the amount of the purchase price and the aggregate par value of all shares held by the company as treasury shares does not exceed 10 percent of the company’s share capital recorded in the Swiss Commercial Register, whereby for purposes of determining whether the 10 percent threshold has been reached, shares repurchased under a share repurchase program for cancellation purposes authorized by the company’s shareholders are disregarded. As of July 29, 2014, Transocean Inc., our wholly owned subsidiary, held as treasury shares approximately three percent of our issued shares. At the annual general meeting in May 2009, the shareholders approved the release of CHF 3.5 billion of additional paid-in capital to other reserves, or freely available reserves as presented on our Swiss statutory balance sheet, to create the freely available reserve necessary for the CHF 3.5 billion share repurchase program for the purpose of the cancellation of shares (the “Currently Approved Program”). At the May 2011 annual general meeting, our shareholders approved the reallocation of CHF 3.2 billion, which is the remaining amount authorized under the share repurchase program, from free reserve to legal reserve, reserve from capital contributions. This amount will continue to be available for Swiss federal withholding tax-free share repurchases. We may only repurchase shares to the extent freely distributable reserves are available. Our board of directors could, to the extent freely distributable reserves are available, authorize the repurchase of additional shares for purposes other than cancellation, such as to retain treasury shares for use in satisfying our obligations in connection with incentive plans or other rights to acquire our shares. Based on the current amount of shares held as treasury shares, approximately seven percent of our issued shares could be repurchased for purposes of retention as additional treasury shares. Although our board of directors has not approved such a share repurchase program for the purpose of retaining repurchased shares as treasury shares, if it did so, any such shares repurchased would be in addition to any shares repurchased under the Currently Approved Program.

Contractual obligations—As of June 30, 2014, there have been no material changes from the contractual obligations as previously disclosed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K for the year ended December 31, 2013, except as noted below.

As of June 30, 2014, our defined benefit pension and other postretirement plans had an aggregate liability of $305 million, representing the aggregate projected benefit obligation, net of the aggregate fair value of plan assets. The carrying amount of this liability is affected by net periodic benefit costs, funding contributions, participant demographics, plan amendments, significant current and future assumptions, and returns on plan assets. Due to the uncertainties resulting from these factors and since the carrying amount is not representative of future liquidity requirements, we have excluded this amount from the contractual obligations presented in the table above. See “—Pension plans and other postretirement benefit plans” and Notes to Condensed Consolidated Financial Statements—Note 12—Postemployment Benefit Plans.

As of June 30, 2014, our unrecognized tax benefits related to uncertain tax positions, net of prepayments of $3 million, represented a liability of $496 million. Due to the high degree of uncertainty regarding the timing of future cash outflows associated with the liabilities recognized in this balance, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities, and we have excluded this amount from the contractual obligations presented in the table above. See Notes to Condensed Consolidated Financial Statements—Note 6—Income Taxes.

Other commercial commitments—As of June 30, 2014, there have been no material changes from the commercial commitments as previously disclosed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K for the year ended December 31, 2013.

Derivative instruments

Our board of directors has approved policies and procedures for derivative instruments that require the approval of our Chief Financial Officer prior to entering into any derivative instruments. From time to time, we may enter into a variety of derivative instruments in connection with the management of our exposure to fluctuations in interest rates or currency exchange rates. We do not enter into derivative transactions for speculative purposes; however, we may enter into certain transactions that do not meet the criteria for hedge accounting. See Notes to Condensed Consolidated Financial Statements—Note 11—Derivatives and Hedging.

Pension plans and other postretirement benefit plans

As of June 30, 2014, there have been no material changes to our pension plans and other postretirement benefit plans as previously disclosed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K for the year ended December 31, 2013, except as noted below.

In June 2014, we committed to freeze benefits of our qualified defined benefit pension plan in the U.S., which covers substantially all U.S. employees, and one of our unfunded supplemental benefit plans, in each case, with an effective date of January 1, 2015. We also committed to enhance the benefits under our defined contribution plan in the U.S. with the same effective date. As a result in the three and six months ended June 30, 2014, we remeasured the funded status of our U.S. defined benefit plan and the unfunded supplemental benefit plan, and we recognized a gain of $6 million associated with curtailments, as a component of net periodic benefit costs.

In February 2014, the Society of Actuaries released drafts of new actuarial tables for applying mortality assumptions to measure the obligations for qualified defined benefit pension plans. We are currently evaluating the application, financial impact and appropriateness of the new mortality table for measuring the funded status of our pension plans.

Contingencies

Except as noted in this report, including in our Notes to Condensed Consolidated Financial Statements—Note 6—Income Taxes, Note 13—Commitments and Contingencies and Note 17—Subsequent Events, there have been no material changes to those actions, claims and other matters pending as discussed in Notes to Consolidated Financial Statements—Note 15—Commitments and Contingencies, Note 27—Subsequent Events and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contingencies—Macondo well incident” in our annual report on Form 10-K for the year ended December 31, 2013. As of June 30, 2014, we were also involved in a number of lawsuits which have arisen in the ordinary course of our business and for which we do not expect the liability, if any, resulting from these lawsuits to have a material adverse effect on our current consolidated financial position, results of operations or cash flows. We can provide no assurance that our expectations as to the outcome or effect of any lawsuit or other matters will prove correct and the eventual outcome of these matters could materially differ from management’s current estimates.

Macondo well incident

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. Eleven persons were declared dead and others were injured as a result of the incident. At the time of the explosion, Deepwater Horizon was located approximately 41 miles off the coast of Louisiana in Mississippi Canyon Block 252 and was contracted to an affiliate of BP plc. (together with its affiliates, “BP”). The rig was declared a total loss. Although we are unable to estimate the full direct and indirect effect that the Macondo well incident will have on our business, the incident has had and could continue to have a material adverse effect on our consolidated statement of financial position, results of operations and cash flows.

We have recognized a liability for estimated loss contingencies associated with litigation and investigations resulting from the incident that we believe are probable and for which a reasonable estimate can be made. At June 30, 2014 and December 31, 2013, the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $432 million and $464 million, respectively, recorded in other current liabilities. The litigation and investigations also give rise to certain loss contingencies that we believe are either reasonably possible or probable but for which we do not believe a reasonable estimate can be made. Although we have not recognized a liability for such loss contingencies, these contingencies could result in liabilities that we ultimately recognize.

We have also recognized an asset associated with the portion of our estimated losses, primarily related to the personal injury and fatality claims of our crew and vendors, that we believe is probable of recovery from insurance. At June 30, 2014 and December 31, 2013, the insurance recoverable asset was $10 million, recorded in other assets. 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. Our estimates involve a significant amount of judgment. As a result of new information or future developments, we may increase our estimated loss contingencies arising out of the Macondo well incident or reduce our estimated recoveries from insurance, and the resulting losses could have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

We can provide no assurance as to the outcome of the trial, the timing of any upcoming phase of trial or ruling, that we will not enter into additional settlements as to some or all of the matters related to the Macondo well incident, including those to be determined at a trial, or the timing or terms of any such settlement. We can provide no assurance as to the estimated costs, insurance recoveries, or other actions that will result from the Macondo well incident.

Multidistrict litigation proceeding—Many of the Macondo well related claims are pending in the U.S. District Court, Eastern District of Louisiana (the “MDL Court”). In March 2012, BP and the Plaintiff’s Steering Committee (the “PSC”) announced that they had agreed to a partial settlement related primarily to private party environmental and economic loss claims as well as response effort related claims (the “BP/PSC Settlement”). On December 21, 2012, the MDL Court granted final approval of the economic and property damage class settlement between BP and the PSC. Various parties who objected to the BP/PSC Settlement filed appeals in the Fifth Circuit Court of Appeals (the “Fifth Circuit”) challenging the MDL Court’s final approval of the BP/PSC Settlement. BP filed appeals in the Fifth Circuit challenging the manner in which the BP/PSC Settlement has been interpreted by the MDL Court with respect to business economic loss claims (“BEL Claims”). In these appeals, BP argues that, if the MDL Court’s interpretation of the settlement with respect to BEL Claims is not overturned, the entire BP/PSC Settlement is invalid and should not have been approved. On October 2, 2013, a panel of the Fifth Circuit issued an opinion questioning the manner in which the settlement has been interpreted with respect to BEL Claims. On December 2, 2013, that panel ordered a temporary halt to certain of the BEL Claims, pending further proceedings in the MDL Court.

On January 10, 2014, another panel of the Fifth Circuit affirmed the MDL Court’s final approval of the BP/PSC Settlement. Thereafter, BP and certain plaintiffs who objected to the settlement filed petitions seeking review by the Fifth Circuit of the legal validity of the BP/PSC Settlement. The PSC moved to dismiss BP’s petition for rehearing for lack of jurisdiction, and on February 20, 2014, the Fifth Circuit granted that motion and dismissed BP’s petition for rehearing. The petitions for rehearing filed by the objectors to the settlement remain pending. The PSC filed its response to these petitions for rehearing on February 6, 2014.

The second phase of the trial began on September 30, 2013, and taking of testimony concluded on October 17, 2013. This phase addressed conduct related to stopping the release of hydrocarbons after April 22, 2010 and quantification of the amount of oil discharged. On December 20, 2013, the parties filed post-trial briefs and proposed findings, and on January 24, 2014, the parties filed reply briefs. The MDL Court has not yet ruled on the issues tried in the first or second phases of the trial.

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

Insurance matters

Our hull and machinery and excess liability insurance program is comprised of commercial market and captive insurance policies that we renew annually on May 1. We periodically evaluate our insurance limits and self-insured retentions. As of July 29, 2014, the insured value of our drilling rig fleet was approximately $27.9 billion, excluding our rigs under construction. We generally do not carry commercial market insurance coverage for loss of revenues, unless it is contractually required, or for losses resulting from physical damage to our fleet caused by named windstorms in the U.S. Gulf of Mexico, including liability for wreck removal costs. See Notes to Condensed Consolidated Financial Statements—Note 13—Commitments and Contingencies.

Tax matters

We are a Swiss corporation, and we operate through our various subsidiaries in a number of countries throughout the world. Our provision for income taxes is based on the tax laws and rates applicable in the jurisdictions in which we operate and earn income. The relationship between our provision for or benefit from income taxes and our income or loss before income taxes can vary significantly from period to period considering, among other factors, (a) the overall level of income before income taxes, (b) changes in the blend of income that is taxed based on gross revenues rather than income before taxes, (c) rig movements between taxing jurisdictions and (d) our rig operating structures. Generally, our annual marginal tax rate is lower than our annual effective tax rate.

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

We file federal and local tax returns in several jurisdictions throughout the world. Tax authorities in certain jurisdictions are examining our tax returns and in some cases have issued assessments. We are defending our tax positions in those jurisdictions. We are also defending against tax-related claims in courts, including our ongoing criminal trial in Norway.

On July 2, 2014, the Norwegian district court in Oslo acquitted our three subsidiaries, two external tax attorneys and an external tax advisor of all criminal charges related to the disclosures in our Norwegian tax returns for the years 1999 through 2002 and statutory financial statements for the years ended December 31, 1996 through 2001. On July 16, 2014, the Norwegian authorities dropped the financial claim of NOK 1.8 billion, equivalent to approximately $300 million, against two of our subsidiaries, fully closing this matter, and on the same date, filed an appeal with respect to the following charges: (a) disclosures in our Norwegian tax returns related to a dividend payment in 2001 (b) disclosures in our Norwegian tax returns related to an intercompany rig sale in 1999 and (c) certain inaccuracies in Norwegian statutory financial statements for the years ended December 31, 1996 through 2001. We believe our Norwegian tax returns are materially correct as filed, and we intend to continue to vigorously contest any assertions to the contrary by the Norwegian civil and criminal authorities in connection with the various transactions being investigated. An unfavorable outcome on the Norwegian civil or criminal tax matters could result in a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

In December 2013, the U.K. Treasury released draft proposals that would cap the amount a U.K.-based contractor would be able to claim as a deductible expense for charter payments made to related companies. A ring fence was also proposed to ensure that the profits from activities in relation to the chartering of rigs from affiliates are not reduced by tax relief from any unconnected activities. On July 17, 2014, the U.K. legislation received Royal Assent with retroactive application effective as of April 2014. As a result, we expect our effective tax rate on our worldwide earnings to increase beginning in the third quarter of 2014.

While we cannot predict or provide assurance as to the final outcome of these proceedings, we do not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations, although it may have a material adverse effect on our consolidated cash flows.

Regulatory matters

For a description of regulatory and environmental matters relating to the Macondo well incident, please see “—Macondo well incident.”

Other matters

In addition, from time to time, we receive inquiries from governmental regulatory agencies regarding our operations around the world, including inquiries with respect to various tax, environmental, regulatory and compliance matters. To the extent appropriate under the circumstances, we investigate such matters, respond to such inquiries and cooperate with the regulatory agencies.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements. This discussion should be read in conjunction with disclosures included in the notes to our condensed consolidated financial statements related to estimates, contingencies and other accounting policies. Significant accounting policies are discussed in Note 2 to our condensed consolidated financial statements in this quarterly report on Form 10-Q and in Note 2 to our consolidated financial statements in our annual report on Form 10-K for the year ended December 31, 2013.

To prepare financial statements, we are required to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to our discontinued operations, allowance for doubtful accounts, materials and supplies obsolescence, investments, property and equipment, goodwill, income taxes, defined benefit pension plans and other postretirement employee benefits, contingent liabilities and share-based compensation. These estimates require significant judgments, assumptions and estimates. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

For a discussion of the critical accounting policies and estimates that we use in the preparation of our condensed consolidated financial statements, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for the year ended December 31, 2013. We have discussed the development, selection and disclosure of these critical accounting policies and estimates with the audit committee of our board of directors. During the six months ended June 30, 2014, there have been no material changes to the types of judgments, assumptions and estimates upon which our critical accounting estimates are based.

New Accounting Pronouncements

For a discussion of the new accounting pronouncements that have had or are expected to have an effect on our condensed consolidated financial statements, see Notes to Condensed Consolidated Financial Statements—Note 3—New Accounting Pronouncements in this quarterly report on Form 10-Q and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for the year ended December 31, 2013.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Overview—We are exposed to interest rate risk primarily associated with our restricted cash investments, our long-term and short-term debt and our derivative instruments. For our restricted cash investments and debt instruments, the following table presents the principal cash flows and related weighted-average interest rates by contractual maturity date. For our derivative instruments, the following table presents the notional amounts and weighted-average interest rates by contractual maturity dates. The information is stated in U.S. dollar equivalents. The instruments are denominated in either U.S. dollars or Norwegian kroner, as indicated. The following table presents information for the twelve-month periods ending June 30 (in millions, except interest rate percentages):

	Scheduled Maturity Date (a)

_____________________________

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

We have engaged in certain hedging activities designed to reduce our exposure to interest rate risk. See Notes to Condensed Consolidated Financial Statements—Note 11—Derivatives and Hedging.

Interest rate risk—At June 30, 2014 and December 31, 2013, the face value of our variable-rate debt was approximately $1.1 billion and $163 million, which represented 10 percent and two percent of the face value of our total debt, respectively, after the effect of our hedging activities. At June 30, 2014, we were exposed to the variable interest rates associated with our interest rate swaps. At December 31, 2013, we were exposed to the variable interest rates associated with borrowings under the ADDCL Credit Facilities. Based upon variable-rate debt amounts outstanding as of June 30, 2014 and December 31, 2013, a hypothetical one percentage point change in annual interest rates would result in a corresponding change in annual interest expense of approximately $11 million and $2 million, respectively.

Currency exchange rate risk—We are exposed to currency exchange rate risk associated with our international operations. For a discussion of our currency exchange rate risk, see “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in our annual report on Form 10-K for the year ended December 31, 2013. There have been no material changes to these previously reported matters during the six months ended June 30, 2014.

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 of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures, as defined in the Exchange Act, Rules 13a-15 and 15d-15, were effective as of June 30, 2014 to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is (1) accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosure and (2) recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms.

Internal controls over financial reporting—There were no changes to our internal controls during the quarter ended June 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

_____________________________

(1)

Total number of shares purchased in the second quarter of 2014 consists of 17,149 shares withheld by us through a broker arrangement and limited to statutory tax in satisfaction of withholding taxes due upon the vesting of restricted shares granted to our employees under our Long-Term Incentive Plan.

(2)

In May 2009, at the annual general meeting of Transocean Ltd., our shareholders approved and authorized our board of directors, at its discretion, to repurchase an amount of our shares for cancellation with an aggregate purchase price of up to CHF 3.5 billion, which is equivalent to approximately $3.9 billion at an exchange rate as of June 30, 2014 of USD 1.00 to CHF 0.89. On February 12, 2010, our board of directors authorized our management to implement the share repurchase program. On May 24, 2013, we received approval from the Swiss authorities for the continuation of the share repurchase program for a further three-year repurchase period through May 23, 2016. We may decide, based upon our ongoing capital requirements, our program of distributions to our shareholders, the price of our shares, matters relating to the Macondo well incident, regulatory and tax considerations, cash flow generation, the amount and duration of our contract backlog, general market conditions, debt rating considerations and other factors, that we should retain cash, reduce debt, make capital investments or acquisitions or otherwise use cash for general corporate purposes, and consequently, repurchase fewer or no additional shares under this program. Decisions regarding the amount, if any, and timing of any share repurchases would be made from time to time based upon these factors. Through June 30, 2014, we have repurchased a total of 2,863,267 of our shares under this share repurchase program at a total cost of $240 million, equivalent to an average cost of $83.74 per share. See “—Sources and uses of liquidity.”
