TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
 
Note 1—Business
Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, "Transocean," "we," "us" or "our") is a leading international provider of offshore contract drilling services for oil and gas wells.  We specialize in technically demanding sectors 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, 2015, we owned or had partial ownership interests in and operated 63 mobile offshore drilling units, including 27 Ultra‑Deepwater Floaters, seven Harsh Environment Floaters, six Deepwater Floaters, 13 Midwater Floaters and 10 High‑Specification Jackups.  At June 30, 2015, we also had seven Ultra‑Deepwater drillships and five High‑Specification Jackups under construction or under contract to be constructed.  See Note 9—Drilling Fleet.
On August 5, 2014, we completed an initial public offering to sell a noncontrolling interest in Transocean Partners LLC ("Transocean Partners"), a Marshall Islands limited liability company, which was formed on February 6, 2014, by Transocean Partners Holdings Limited, a Cayman Islands company and our wholly owned subsidiary, to own, operate and acquire modern, technologically advanced offshore drilling rigs.  See Note 15—Noncontrolling Interest.
Note 2—Significant Accounting Policies
Presentation—We have prepared our accompanying unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States ("U.S.") for interim financial information and with the instructions to Form 10‑Q and Article 10 of Regulation S‑X of the U.S. Securities and Exchange Commission ("SEC").  Pursuant to such rules and regulations, these financial statements do not include all disclosures required by accounting principles generally accepted in the U.S. for complete financial statements.  The condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary for a fair presentation of financial position, results of operations and cash flows for the interim periods.  Such adjustments are considered to be of a normal recurring nature unless otherwise noted.  Operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 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, 2014 and 2013 and for each of the three years in the period ended December 31, 2014 included in our annual report on Form 10‑K filed on February 26, 2015.
Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted in the U.S., we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities.  On an ongoing basis, we evaluate our estimates and assumptions, including those related to our allowance for doubtful accounts, materials and supplies obsolescence, assets held for sale, property and equipment, investments, 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.  We separately present within equity on our condensed consolidated balance sheets the ownership interests attributable to parties with noncontrolling interests in our consolidated subsidiaries, and we separately present net income attributable to such parties on our condensed consolidated statements of operations.  See Note 4—Variable Interest Entities and Note 15—Noncontrolling Interest.

Property and equipment—The carrying amounts of our property and equipment, consisting primarily of offshore drilling rigs and related equipment, are based on our estimates, assumptions and judgments relative to capitalized costs, useful lives and salvage values of our rigs.  These estimates, assumptions and judgments reflect both historical experience and expectations regarding future industry conditions and operations.  At June 30, 2015, the aggregate carrying amount of our property and equipment represented approximately 73 percent of our total assets.
We compute depreciation using the straight‑line method after allowing for salvage values.  In December 2014, we reduced the salvage values of certain drilling units due to existing market conditions.  In the three and six months ended June 30, 2015, this change in estimate resulted in increased depreciation expense of $14 million ($14 million, or $0.04 per diluted share, net of tax) and $44 million ($42 million, or $0.12 per diluted share, net of tax), respectively.  For the year ending December 31, 2015, we expect this change in estimate to result in increased depreciation expense of approximately $51 million ($49 million, net of tax).
Sharebased compensation—In the three and six months ended June 30, 2015, we recognized share‑based compensation expense of $14 million and $33 million, respectively.  In the three and six months ended June 30, 2014, we recognized share‑based compensation expense of $23 million and $51 million, respectively.
Capitalized interest—We capitalize interest costs for qualifying construction and upgrade projects.  In the three and six months ended June 30, 2015, we capitalized interest costs on construction work in progress of $29 million and $55 million, respectively.  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.
Reclassifications—We have made certain reclassifications to prior period amounts to conform with the current period's presentation.  Such 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 18—Subsequent Events.
Note 3—New Accounting Pronouncements
Recently adopted accounting standards
Presentation of financial statements—Effective January 1, 2015, we adopted 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 and does not apply to components, such as our discontinued operations, that have been evaluated and reported as discontinued operations under previous guidance.  Our adoption did not have an effect on our condensed consolidated financial statements or the disclosures contained in our notes to condensed consolidated financial statements.
Recently issued accounting standards
Interest—Effective January 1, 2016, we will adopt the accounting standards update that requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts.  The update is effective for interim and annual periods beginning after December 15, 2015, and early adoption is permitted.  At June 30, 2015 and December 31, 2014, the aggregate carrying amount of the debt issue costs related to our recognized debt liabilities was $46 million and $51 million, respectively, recorded in other assets.  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.
Presentation of financial statementsEffective with our annual report for the period ending December 31, 2016, we will adopt the accounting standards update that requires us to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued.  The update is effective for the annual period ending after December 15, 2016 and for interim and annual periods thereafter.  We do not expect that our adoption will have a material effect on the disclosures contained in our notes to condensed consolidated financial statements.
Revenue from contracts with customers—Effective January 1, 2018, we will adopt the 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 was originally effective for interim and annual periods beginning on or after December 15, 2016, but has since been approved for a one‑year deferral, effective for interim and annual periods beginning on or after December 15, 2017 and permits adoption as early as the original effective date.  We are evaluating the requirements to determine the effect such requirements may have on our revenue recognition policies.

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):

Note 5—Impairments
Assets held and used—During the three months ended March 31, 2015, we identified indicators that the asset groups in our contract drilling services reporting unit may not be recoverable.  Such indicators included a reduction in the number of new contract opportunities, recent low dayrate fixtures and contract terminations.  Our Deepwater Floater asset group, in particular, has experienced further declines in projected dayrates and utilization partly caused by more technologically advanced drilling units aggressively competing with less capable drilling units.  As a result of our testing, we determined that the carrying amount of the Deepwater Floater asset group was impaired.  In the six months ended June 30, 2015, we recognized a loss of $507 million ($481 million, or $1.33 per diluted share, net of tax), associated with the impairment of these long‑lived assets, including a loss of $41 million associated with construction in progress for the Deepwater Floater asset group.
During the three months ended June 30, 2015, we identified additional indicators that the asset groups in our contract drilling services reporting unit may not be recoverable.  Such indicators included additional customer suspensions of drilling programs and cancellations of contracts, further reduction in the number of new contract opportunities, resulting in reduced dayrate fixtures.  Our Midwater Floater asset group, specifically, experienced further declines in projected dayrates and utilization as drilling activity has sharply declined in the U.K. and Norwegian North Sea, which has accelerated the marginalization of some of the less capable drilling units in this asset group.  As a result of our testing, we determined that the carrying amount of the Midwater Floater asset group was impaired.  In the three and six months ended June 30, 2015, we recognized a loss of $668 million ($653 million, or $1.79 per diluted share, net of tax) associated with the impairment of these long‑lived assets, including a loss of $11 million associated with construction in progress for the Midwater Floater asset group.
In each case, we measured the fair value of the asset group by applying a combination of income and cost approaches, using projected discounted cash flows and estimates of the exchange price that would be received for the assets in the principal or most advantageous market for the assets in an orderly transaction between market participants as of the measurement date.  Our estimates of fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of our contract drilling services reporting unit, such as future commodity prices, projected demand for our services, rig availability and dayrates.  If we experience increasingly unfavorable changes to actual or anticipated dayrates or other impairment indicators, or if we are unable to secure new or extended contracts for our active units or the reactivation of any of our stacked units, we may be required to recognize additional losses in future periods as a result of impairments of the carrying amount of one or more of our asset groups.
Assets held for sale—In the three months ended June 30, 2015, we recognized an aggregate loss of $222 million ($144 million, or $0.39 per diluted share, net of tax), associated with the impairment of the Ultra‑Deepwater Floater GSF Explorer, the Deepwater Floater GSF Celtic Sea and the Midwater Floater Transocean Amirante along with related equipment, which were classified as held for sale at the time of impairment.  In the six months ended June 30, 2015, we recognized an aggregate loss of $651 million ($537 million, or $1.48 per diluted share, net of tax), associated with the impairment of the Ultra‑Deepwater Floaters Deepwater Expedition and GSF Explorer, the Deepwater Floaters GSF Celtic Sea, Sedco 707 and Transocean Rather and the Midwater Floaters GSF Aleutian Key, GSF Arctic III, Transocean Amirante and Transocean Legend, along with related equipment, which were classified as assets held for sale at the time of impairment.  We measured the impairment 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 indicative market values for the drilling units and related equipment to be sold for scrap value.  If we commit to plans to sell additional rigs for scrap value, we may be required to recognize additional losses in future periods associated with the impairment of such assets.
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 indicative market values for comparable drilling units or a binding sale and purchase agreement for the drilling unit and related equipment.

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, 2015 and 2014, our estimated annual effective tax rates were 21.6 percent and 13.8 percent, respectively, based on estimated annual 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.
In December 2014, the U.K. Treasury released a draft proposal that would impose tax on groups that use certain tax planning techniques that are perceived as diverting profits from the U.K.  The Diverted Profit Tax rule was included in the 2015 Finance Bill and on March 26, 2015, the legislation received Royal Assent with an effective date of April 1, 2015.  The change in the law did not affect our existing annual income tax rate or deferred tax balances.
Deferred taxes—The valuation allowance for our non‑current deferred tax assets was as follows (in millions):

2015
   
December 31,
2014
 
Valuation allowance for non‑current deferred tax assets
 
$
409
   
$
340
 

The increase in the valuation allowance for our non‑current deferred tax assets was primarily related to the current net operating losses generated in Norway and the U.K. carryforward deductions related to charter payments.
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,
2015
   
December 31,
2014

Unrecognized tax benefits, including interest and penalties
 
$
401
   
$
385
 

In the year ending December 31, 2015, 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 20 years.  Tax authorities in certain jurisdictions are examining our tax returns and in some cases have issued assessments.  We are defending our tax positions in those jurisdictions.  While we cannot predict or provide assurance as to the timing or the outcome of these proceedings, we do not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of operations, although it may have a material adverse effect on our consolidated statement of cash flows.
U.S. tax investigations—In January 2014, we received a draft 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.  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.  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.

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.  Excluding one assessment that was formally dismissed, the authorities issued the following tax assessments: (a) NOK 412 million, equivalent to approximately $52 million, plus interest, related to a 2001 dividend payment and (b) NOK 43 million, equivalent to approximately $5 million, plus interest, related to certain foreign exchange deductions and dividend withholding tax.  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 $52 million, but waived all penalties and interest.  On September 12, 2014, we filed an appeal.  We intend to take all 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 $229 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 $29 million, against three of our subsidiaries in addition to any civil tax penalties and the financial claim.
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 $229 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.
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 730 million, equivalent to approximately $235 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 128 million, equivalent to approximately $41 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, employee contribution requirements and tax attributes.  From time to time, we may identify changes to previously evaluated tax positions that could result in adjustments to our recorded assets and liabilities.  Although we are unable to predict the outcome of these changes, we do not expect the effect, if any, resulting from these adjustments to have a material adverse effect on our 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 agreed to remit the collections from our customers under the associated drilling contracts to Shelf Drilling, and Shelf Drilling 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, exceeded the amounts we received from Shelf Drilling for providing such services.
Under the operating agreements, we agreed to operate the standard jackups on behalf of Shelf Drilling for periods ranging from nine months to 27 months, until expiration or novation of the underlying drilling contracts by Shelf Drilling, the last of which was completed in January 2015.  Until the expiration or novation of such drilling contracts, we retained possession of the materials and supplies associated with the standard jackups that we operated under the operating agreements.  In the three and six months ended June 30, 2015, we received cash proceeds of $1 million and $3 million, respectively, 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, 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.
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, 2015 and December 31, 2014, we had $84 million and $91 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.
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.
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.  We also agreed to provide a $15 million working capital line of credit to the buyer through March 2016.  At December 31, 2014, ADTI owed to us borrowings of $15 million outstanding under the working capital line of credit, recorded in other assets.  In May 2015, ADTI repaid the borrowings and terminated the credit agreement.

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 "Five‑Year Revolving Credit Facility").  Among other things, the Five‑Year Revolving Credit Facility includes limitations on creating liens, incurring subsidiary debt, transactions with affiliates, sale/leaseback transactions, mergers and the sale of substantially all assets.  The Five‑Year Revolving Credit Facility also includes a covenant imposing a maximum debt to tangible capitalization ratio of 0.6 to 1.0.  Borrowings under the Five‑Year Revolving Credit Facility are subject to acceleration upon the occurrence of an event of default, borrowings are guaranteed by Transocean Ltd. and may be prepaid in whole or in part without premium or penalty.
We may borrow under the Five‑Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate ("LIBOR") plus a margin (the "Five‑Year Revolving Credit Facility Margin"), which ranges from 1.125 percent to 2.0 percent based on the 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 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.  Effective March 19, 2015, as a result of a reduction of our Debt Rating, the Five‑Year Revolving Credit Facility Margin increased to 1.75 percent from 1.5 percent and the facility fee increased to 0.275 percent from 0.225 percent.  At June 30, 2015, we had no borrowings outstanding or letters of credit issued, and we had $3.0 billion of available borrowing capacity under the Five‑Year Revolving Credit Facility.
4.95% Senior Notes—In September 2010, we issued $1.1 billion aggregate principal amount of 4.95% Senior Notes due November 2015 (the "4.95% Senior Notes").  We may redeem some or all of the 4.95% Senior Notes at any time at a redemption price equal to 100 percent of the principal amount plus accrued and unpaid interest, if any, and a make‑whole premium.  On June 26, 2015, we announced our intent to redeem the 4.95% Senior Notes.  At June 30, 2015 and December 31, 2014, the aggregate outstanding principal amount of the 4.95% Senior Notes was $893 million.  See Note 18—Subsequent Events.
5.05% Senior Notes, 6.375% Senior Notes and 7.35% Senior Notes—In December 2011, we issued $1.0 billion aggregate principal amount of 5.05% Senior Notes due December 2016 (the "5.05% Senior Notes"), $1.2 billion aggregate principal amount of 6.375% Senior Notes due December 2021 (the "6.375% Senior Notes") and $300 million aggregate principal amount of 7.35% Senior Notes due December 2041 (the "7.35% Senior Notes").  The interest rates for the notes are subject to adjustment from time to time upon a change to our Debt Rating.  Effective June 15, 2015, as a result of a reduction of our Debt Rating, the interest rates on the 5.05% Senior Notes, the 6.375% Senior Notes and the 7.35% Senior Notes increased 0.5 percent from the stated rate to 5.55 percent, 6.875 percent and 7.85 percent, respectively.  At June 30, 2015, the aggregate outstanding principal amount of the 5.05% Senior Notes, the 6.375% Senior Notes and the 7.35% Senior Notes was $1.0 billion, $1.2 billion and $300 million, respectively.
2.5% Senior Notes and 3.8% Senior Notes—In September 2012, we issued $750 million aggregate principal amount of 2.5% Senior Notes due October 2017 (the "2.5% Senior Notes") and $750 million aggregate principal amount of 3.8% Senior Notes due October 2022 (the "3.8% Senior Notes").  The interest rates for the notes are subject to adjustment from time to time upon a change to our Debt Rating.  Effective April 15, 2015, as a result of a reduction of our Debt Rating, the interest rates on the 2.5% Senior Notes and the 3.8% Senior Notes increased 0.5 percent from the stated rate to 3.0 percent and 4.3 percent, respectively.  At June 30, 2015, the aggregate outstanding principal amount of the 2.5% Senior Notes and the 3.8% Senior Notes was $750 million each.

Eksportfinans Loans—We have borrowings under the Loan Agreement dated September 12, 2008 and the Loan Agreement dated November 18, 2008, between one of our subsidiaries and Eksportfinans ASA (together, the "Eksportfinans Loans").  At June 30, 2015 and December 31, 2014, aggregate borrowings of NOK 2.3 billion and NOK 2.8 billion, respectively, equivalent to approximately $297 million and $370 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, 2015 and December 31, 2014, the aggregate principal amount of the Aker Restricted Cash Investments was NOK 2.3 billion and NOK 2.8 billion, respectively, equivalent to approximately $297 million and $370 million, respectively.
Note 11—Derivatives and Hedging
In the six months ended June 30, 2014, we entered into interest rate swaps, which qualified for and we designated 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, respectively.  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 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.  During the three months ended June 30, 2015, we terminated the interest rate swaps designated as a fair value hedge of the 6.5% Senior Notes, and in the three months ended June 30, 2015, we received an aggregate net cash payment of $24 million in connection with the settlement.

Note 12—Postemployment Benefit Plans
Effective January 1, 2015, we froze the benefits of our qualified defined benefit pension plan in the U.S., which covered substantially all U.S. employees, and one of our unfunded supplemental benefit plans.  Including these plans, we have several frozen defined benefit pension plans, both funded and unfunded, that cover certain current and former U.S. employees and certain former 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 certain current and former employees in those areas (the "Non‑U.S. Plans").  Additionally, we maintain several unfunded contributory and noncontributory other postretirement employee benefit plans covering substantially all of our U.S. employees (the "OPEB Plans").

Note 13—Commitments and Contingencies
Macondo well incident settlement obligations
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 died in, 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").  Litigation commenced shortly after the incident, and most claims against us were consolidated by the U.S. Judicial Panel on Multidistrict Litigation and transferred to the U.S. District Court for the Eastern District of Louisiana (the "MDL Court").  A significant portion of the contingencies arising from the Macondo well incident has now been resolved as a result of settlements with the U.S. Department of Justice (the "DOJ"), BP, and the Plaintiffs' Steering Committee (the "PSC").
U.S. Department of Justice settlement agreements—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.  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, excluding interest, in scheduled installments through February 2017.  In the six months ended June 30, 2015 and 2014, we paid an aggregate installment of $264 million and $472 million, respectively, including interest, towards our obligations under the Plea Agreement and Consent Decree.  At June 30, 2015, we had satisfied our financial obligations under the Consent Decree and had $120 million outstanding under the Plea Agreement.
Macondo well incident contingencies
Overview—During the three months ended June 30, 2015, in connection with the settlements, as further described below, we adjusted our assets and liabilities associated with contingencies resulting from the Macondo well incident.  In the three and six months ended June 30, 2015, we recognized income of $788 million ($735 million, or $2.02 per diluted share, net of tax), recorded as a net reduction to operating and maintenance costs and expenses, including $538 million associated with recoveries from insurance for our previously incurred losses, $125 million associated with partial reimbursement from BP for our previously incurred legal costs, and $125 million associated with a net reduction to certain related contingent liabilities, primarily associated with contingencies that have either been settled or otherwise resolved as a result of settlements with BP and the PSC.  We made such adjustments with corresponding entries to increase accounts receivable by $663 million and decrease other current liabilities by $125 million.  In the three and six months ended June 30, 2015, we received cash proceeds of $445 million from insurance recoveries.  See Note 18—Subsequent Events.
We have recognized a liability for the remaining estimated loss contingencies associated with litigation resulting from the Macondo well incident that we believe are probable and for which a reasonable estimate can be made.  At June 30, 2015 and December 31, 2014, the liability for estimated loss contingencies that we believe are probable and for which a reasonable estimate can be made was $291 million and $426 million, respectively, recorded in other current liabilities.  The liability for estimated loss contingencies at June 30, 2015, included, among others, the amount we have agreed to pay as a result of our settlement with the PSC, which is subject to approval by the MDL Court (see "—PSC Settlement Agreement" below).  The remaining litigation could result in 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 believe the remaining most notable claims against us arising from the Macondo well incident are the potential settlement class opt‑outs from the PSC Settlement Agreement and the claims individual states may have against us for fines, penalties or punitive damages for which we are not indemnified by BP (see "—BP Settlement Agreement" below).
We have also recognized an asset associated with the portion of our estimated losses that we believe is probable of recovery from insurance and for which we had received from underwriters confirmation of expected payment.  At June 30, 2015 and December 31, 2014, the insurance recoverable asset was $93 million, recorded in accounts receivable (see Note 18—Subsequent Events), and $10 million, recorded in other assets, respectively.  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.
The Consent Decree resolved the claim by the U.S. for civil penalties under the Clean Water Act.  The Consent Decree did not resolve United States' claim under the Oil Pollution Act ("OPA") for natural resource damages ("NRD") or for removal costs.  However, BP has agreed to indemnify us for NRD and most removal costs as further discussed under "—BP Settlement Agreement" and "—Pending Claims" below.

BP Settlement Agreement—On May 20, 2015, we entered into a confidential settlement agreement with BP (the "BP Settlement Agreement").  We believe the BP Settlement Agreement resolves all Macondo well-related litigation between BP and us, and the indemnity BP has committed to provide will generally address claims by third parties, including claims for economic and property damages, economic loss and NRD.  However, the indemnity obligations do not extend to fines, penalties, or punitive damages.  The BP Settlement Agreement generally provides that:
§
BP will pay us $125 million, as noted above, towards the legal costs we have incurred in connection with the Macondo well incident;
§
BP will indemnify us for compensatory damages, including all natural resource damages and all cleanup and removal costs incurred before the date of the settlement and any future cleanup and removal costs for oil or pollutants originating from the Macondo well;
§
We will indemnify BP for personal and bodily injury claims of our employees and for any future costs for the cleanup or removal of pollutants stored on the Deepwater Horizon vessel;
§
BP will no longer attempt to recover as an "additional insured" under our excess liability insurance policies, and BP will be bound to the MDL Court's and Texas Supreme Court's insurance reimbursement rulings for the Macondo well litigation;
§
BP and we will each release and withdraw all claims we have against each other arising from the Macondo well litigation; and
§
Neither BP nor we will make statements asserting the other company's conduct was grossly negligent in the Macondo well incident.

PSC Settlement Agreement—On May 29, 2015, together with the PSC, we filed a settlement agreement (the "PSC Settlement Agreement") with the MDL Court finalizing the terms as initially agreed to by us and the PSC in a Term Sheet Agreement on May 20, 2015.  The PSC Settlement Agreement is subject to approval by the MDL Court.  Through the PSC Settlement Agreement, we have agreed to pay a total of $212 million, plus up to $25 million for partial reimbursement of attorneys' fees, to be allocated between two classes of plaintiffs as follows: (1) private plaintiffs, businesses, and local governments who could have asserted punitive damages claims against us under general maritime law (the "Punitive Damages Class"); and (2) private plaintiffs who previously settled economic damages claims against BP and were assigned certain claims BP had made against us.  A court‑appointed neutral representative will allocate the payment between the two classes.  In exchange for these payments, each of the classes will release all respective claims it has against us.  Members of the Punitive Damages Class may opt out of the PSC Settlement Agreement and continue to pursue punitive damages claims against us, but we may terminate the PSC Settlement Agreement if the number of opt outs exceeds the specified threshold amount.
Multidistrict litigation proceeding—Most Macondo well related claims against us have been resolved by our settlements with the DOJ, BP, and the PSC.  There are, however, still pending claims by state governments, potential opt‑outs from the settlement with the PSC, and a number of other parties.  As of June 30, 2015, the MDL Court has completed two trials involving us, and additional litigation and appeals continue.
Phase One trial—The Phase One trial in 2013 addressed fault for the Macondo blowout and resulting oil spill.  The MDL Court's September 2014 Phase One ruling concluded that BP was grossly negligent and reckless and 67 percent at fault for the blowout, explosion, and spill; that we were negligent and 30 percent at fault; and that Halliburton Company ("Halliburton") was negligent and three percent at fault.
The finding that we were negligent, but not grossly negligent, meant that, subject to a successful appeal, we would not be held liable for punitive damages and that BP was required to honor its contractual agreements to indemnify us for compensatory damages and release its claims against us.  Our settlements with BP and the PSC finally resolve the indemnity and release issues (see "—BP Settlement Agreement" and "—PSC Settlement Agreement") and largely eliminate our risk should these determinations be reversed through the appeal process.
The MDL Court also concluded that we were an "operator" of the Macondo well for purposes of 33 U.S.C. § 2704(c)(3), a provision of the Oil Pollution Act ("OPA") that permits government entities to recover removal costs by owners and operators of a facility or vessel that caused a discharge.  The MDL Court, however, found that "Transocean's liability to government entities for removal costs is ultimately shifted to BP by virtue of contractual indemnity," and BP has agreed to indemnify removal costs through the BP Settlement Agreement (see "—BP Settlement Agreement").
The Phase One ruling did not quantify damages or result in a final monetary judgment.  However, because it is a determination of liability under maritime law, the Phase One ruling is appealable, and we, along with BP, the PSC, Halliburton and the State of Alabama have each appealed or cross-appealed aspects of the ruling.  These appeals have been stayed.  See Note 18—Subsequent Events.
We can provide no assurances as to the outcome of these appeals, as to the timing of any further rulings, or 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.
Pending claims—As of June 30, 2015, approximately 1,398 actions or claims are pending against us, along with other unaffiliated defendants arising from individual complaints as well as putative class-action complaints that were filed in the federal and state courts in Louisiana, Texas, Mississippi, Alabama, Georgia, Kentucky, South Carolina, Tennessee, Florida and other courts.  These claims were originally filed in various state and federal courts, and most have been consolidated in the MDL Court.  We believe our settlement with the PSC, if approved by the MDL Court, will resolve many of these pending actions.  As for any actions not resolved by these settlements, including any remaining personal injury claims, any claims by individuals who opt‑out of the PSC Settlement Agreement, claims by State governments, claims by private environmental groups, and securities actions, we are vigorously defending those claims and pursuing any and all defenses available.

Wrongful death and personal injury claims—As of June 30, 2015, two personal injury claims have not yet been settled.  These claims are not indemnified by BP.
State and other government claims—Claims have been filed against us by over 200 state, local and foreign governments, including the States of Alabama, Florida, Louisiana, Mississippi and Texas; the Mexican States of Veracruz, Quintana Roo, Tamaulipas and Yucatan; the federal government of Mexico and other local governments by and on behalf of multiple towns and parishes.
The MDL Court dismissed damages claims brought under state common and statutory law and subsequently dismissed civil penalty claims brought under state statutory law.  Certain Louisiana parishes appealed the dismissal of their civil penalty claims brought under Louisiana law.  The Fifth Circuit affirmed the MDL Court's dismissal of these claims, and the U.S. Supreme Court denied certiorari.
The state, local and foreign government claims include claims under OPA for economic damages, natural resource damages and removal costs.  As noted above, BP has agreed to indemnify us for these damages (see "—Macondo well incident settlement obligations").    Our settlement with the PSC, if approved by the MDL Court will resolve the punitive damages claims of local governments that do not opt out of the settlement.  However, the States with whom we have not settled may continue to pursue punitive damages claim by appealing the MDL Court's determination that we were not grossly negligent in connection with the blowout.  The OPA claims of the Mexican States of Veracruz, Quintana Roo, Tamaulipas and Yucatan were dismissed for failure to demonstrate that recovery under OPA was authorized by treaty or executive agreement.  The MDL Court subsequently granted summary judgment and the Fifth Circuit upheld the decision on the Mexican States' general maritime law claims on the ground that the federal government of Mexico, rather than the Mexican States, had the proprietary interest in the claims.  Accordingly, we believe we will be indemnified for all OPA claims from the Mexican States through the BP Settlement Agreement.
Citizen suits under environmental statutes—The Center for Biological Diversity (the "Center"), a private environmental group, sued BP and us 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 the dismissal with one exception: the Fifth Circuit remanded to the MDL Court the Center's claim for injunctive relief, but not for penalties, based on BP and our alleged failure to make certain reports about the constituents of oil spilled into the U.S. Gulf of Mexico as required by the Emergency Planning and Community Right‑to‑Know Act of 1986.  In April 2014, BP and we moved for summary judgment and 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.  The MDL Court has not indicated when it will rule on the motions.
Federal securities claims—On September 30, 2010, a proposed federal securities class action was filed in the U.S. District Court for the Southern District of New York, naming us, 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 relating to our shareholder meeting in connection with the merger with the acquired company violated Section 14(a) of the U.S. Securities Exchange Act of 1934, as amended (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 the plaintiff and the proposed class members.  In connection with this action, 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.  On March 11, 2014, the District Court for the Southern District of New York dismissed the claims as time-barred.  Plaintiffs appealed to the U.S. Court of Appeals for the Second Circuit.  Oral argument has been set for August 18, 2015.
Wreck removal—By letter dated December 6, 2010, the U.S. Coast Guard requested that we formulate and submit a comprehensive oil removal plan to remove any diesel fuel 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 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, which are 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.  Under the BP Settlement Agreement, we have agreed to indemnify BP for any costs associated with wreck removal.
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, the policy forms for all layers include coverage for personal injury and fatality claims, subject to reasonableness determinations, of our crew and vendors, for which indemnity agreements are in place as to the latter, actual and compensatory damages, punitive damages and related legal defense costs.  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 claiming an entitlement to unlimited "additional insured" status under our excess liability insurance program.  In response, our wholly owned captive insurance subsidiary and our first four excess layer insurers filed declaratory judgment actions in May 2010 seeking a declaration that they have limited additional insured obligations to BP.  The MDL Court ruled that BP's coverage rights are limited to the scope of our indemnification of BP in the drilling contract, and the Texas Supreme Court later made the same ruling.  Under the BP Settlement Agreement, BP has agreed to accept the rulings of the MDL Court and Texas Supreme Court for purposes of this litigation and to discontinue its attempts to recover as an additional insured under our liability insurance policies (see "—BP Settlement Agreement").  Accordingly, consistent with the rulings of the MDL Court and Texas Supreme Court, we have recognized and confirmed recovery of insurance proceeds through the fourth layer, which is now exhausted.
We have asserted claims to an additional $250 million of insurance coverage in the fifth layer of excess coverage comprised of Bermuda market insurers ("Bermuda Insurers").  The Bermuda Insurers have, in turn, commenced discussions regarding applicability of coverage.
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 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.  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.  The plaintiffs generally seek awards of unspecified compensatory and punitive damages, but the court-appointed special master has ruled that a Jones Act employer defendant, such as us, cannot be sued for punitive damages.  After ten years of litigation, this group of cases has been winnowed to the point where now only 15 plaintiffs' individual claims remain pending in Mississippi in which we have or may have an interest.
During the year ended December 31, 2014, a group of lawsuits premised on the same allegations as those in Mississippi were filed in Louisiana.  As of June 30, 2015, eight plaintiffs have claims pending against one or more of our subsidiaries in four different lawsuits filed 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, 2015, the subsidiary was a defendant in approximately 672 lawsuits, some of which include multiple plaintiffs, and we estimate that there are approximately 921 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, 2015, 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 435 million, equivalent to approximately $140 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 546 million, equivalent to approximately $176 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 36 million, equivalent to approximately $12 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 was filed in November 2014 and accepted for review in April 2015.  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.
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 assessing Petrobras for withholding taxes presumably due and unpaid on payments made in 2008 and 2009 to beneficiaries domiciled outside of Brazil in connection with the charter agreements related to work performed by its contractors, including us.  Petrobras contracts include a structure for chartering vessels owned by entities not domiciled in Brazil.  Petrobras is challenging such tax assessment and has indicated that, if it loses the tax dispute, it will seek to recover from its contractors, including us, any taxes, penalties, interest and fees that Petrobras is being requested to pay.  Petrobras has informed us that it has received from the RFB notices of deficiencies for BRL 283 million, equivalent to approximately $91 million, excluding penalties, interest and fees, related to work performed by us.  We have informed Petrobras that we believe it has no basis for seeking reimbursement from us, and we intend to vigorously challenge any assertions to the contrary.  Effective January 1, 2015, the Brazilian Government enacted a new law that expressly applies zero rate withholding to charter payments made in connection with a vessel to a beneficiary domiciled outside of Brazil when the agreement is entered into jointly with a services contract to operate the vessel.  All of our charter contracts with Petrobras met the criteria for such withholding.  While the law and ruling are not retroactive, such rulings strengthen Petrobras' argument for challenging the RFB tax assessment.  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.
Nigerian Cabotage Act litigation—In October 2007, three of our subsidiaries were each served a Notice and Demand from the Nigeria Maritime Administration and Safety Agency, imposing a two percent surcharge on the value of all contracts performed by us in Nigeria pursuant to the Coastal and Inland Shipping (Cabotage) Act 2003 (the "Cabotage Act").  Our subsidiaries each filed an originating summons in the Federal High Court in Lagos challenging the imposition of this surcharge on the basis that the Cabotage Act and associated levy is not applicable to drilling rigs.  The respondents challenged the competence of the suits on several procedural grounds.  The court upheld the objections and dismissed the suits.  In December 2010, our subsidiaries filed a new joint Cabotage Act suit.  While we cannot predict or provide assurance as to the outcome of these proceedings, we do not expect it to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.
Other matters—We are involved in various tax matters, various regulatory matters, and a number of claims and lawsuits, asserted and unasserted, all of which have arisen in the ordinary course of our business.  We do not expect the liability, if any, resulting from these other matters to have a material adverse effect on our consolidated statement of financial position, results of operations or cash flows.  We cannot predict with certainty the outcome or effect of any of the litigation matters specifically described above or of any such other pending, threatened, or possible litigation or liability.  We can provide no assurance that our beliefs or expectations as to the outcome or effect of any tax, regulatory, lawsuit or other litigation matter will prove correct and the eventual outcome of these matters could materially differ from management's current estimates.
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.

Resolutions of other claims by the EPA, the involved state agency or PRPs are at various stages of investigation.  These investigations involve determinations of (a) the actual responsibility attributed to us and the other PRPs at the site, (b) appropriate investigatory or remedial actions and (c) allocation of the costs of such activities among the PRPs and other site users.  Our ultimate financial responsibility in connection with those sites may depend on many factors, including (i) the volume and nature of material, if any, contributed to the site for which we are responsible, (ii) the number of other PRPs and their financial viability and (iii) the remediation methods and technology to be used.
It is difficult to quantify with certainty the potential cost of these environmental matters, particularly in respect of remediation obligations.  Nevertheless, based upon the information currently available, we believe that our ultimate liability arising from all environmental matters, including the liability for all other related pending legal proceedings, asserted legal claims and known potential legal claims 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, 2015, the insured value of our drilling rig fleet was approximately $25.0 billion, excluding our rigs under construction.  We generally do not carry commercial market insurance coverage for loss of revenues 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, 2015, 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 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, 2015, we carried excess liability coverage of $700 million in the commercial market excluding the 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 separate $10 million per occurrence deductibles on collision liability claims and $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, 2015, 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, 2015 and December 31, 2014, we had outstanding letters of credit totaling $270 million and $338 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 $84 million and $91 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, 2015 and December 31, 2014, we had outstanding surety bonds totaling $6 million.
