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 ultra-deepwater and harsh environment drilling services. Our mobile offshore drilling fleet is considered one of the most versatile fleets in the world. We contract our drilling rigs, related equipment and work crews predominantly on a dayrate basis to drill oil and gas wells. As of June 30, ~~2020,~~2021, we owned or had partial ownership interests in and operated a fleet of 3937 mobile offshore drilling units, including 27 ultra-deepwater floaters and 1210 harsh environment floaters. As of June 30, ~~2020,~~2021, we were constructing 2 ultra-deepwater drillships.

Note 2—Significant Accounting Policies

Presentation—We 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. 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, ~~2020,~~2021, are not necessarily indicative of the results that may be expected for the year ending December 31, ~~2020,~~2021, 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, ~~2019~~2020 and ~~2018,~~2019, and for each of the three years in the period ended December 31, ~~2019,~~2020, included in our annual report on Form 10-K filed on ~~February 18, 2020.~~March 1, 2021.

Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted in the U.S., we must 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 credit losses,~~income taxes, property and equipment, equity investments, contingencies, allowance for excess ~~and obsolete~~ materials and supplies, assets held for sale, ~~property and equipment,~~ intangibles, allowance for credit losses, leases, ~~income taxes, contingencies,~~ share-based compensation and postemployment benefit plans. We base our estimates and assumptions on historical experience and other factors that we believe are reasonable. 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 a valuation requires multiple input levels, 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.

Note 3—Accounting Standards Update

Recently adopted accounting standards

~~Financial instruments – credit losses~~Debt with conversion and other options—Effective January 1, ~~2020,~~2021, we early adopted the accounting standards update that ~~requires entities to estimate an expected lifetime credit loss on financial assets ranging~~simplifies the accounting for convertible instruments, such as our exchangeable debt, by limiting the accounting models that result in separately recognizing embedded conversion features from short-term trade accounts receivable to long-term financings. Our accounts receivable represent consideration earned for performing services in various countries for our customers, including integrated oil companies, government-owned or government-controlled oil companies and other independent oil companies, the ~~majority of which currently have corporate family investment grade credit ratings. We established procedures to apply the requirements of the~~host contract. The accounting standards update ~~using~~also enhances information transparency by making targeted improvements to the ~~loss-rate method by reviewing our historical credit losses~~disclosures for convertible instruments and ~~evaluating future expectations, and we recorded the initial estimated allowance with a corresponding entry to accumulated deficit.~~earnings-per-share guidance. Our adoption did not result in any accounting changes for the 0.50% exchangeable senior bonds due January 2023 (the “0.50% Exchangeable Senior Bonds”) or the 2.50% senior guaranteed exchangeable bonds due January 2027 (the “2.50% Senior Guaranteed Exchangeable Bonds”). Under previous accounting guidance, for the 4.00% Senior Guaranteed Exchangeable Bonds due December 2025 (the “4.00% Senior Guaranteed Exchangeable Bonds”), we would have recorded the debt and exchange features separately and, consequently, we would have recognized in current and future periods greater amortization, as a ~~material effect on our condensed consolidated statements~~component of ~~financial position, operations or cash flows or on the disclosures contained in our notes to condensed consolidated financial statements.~~interest expense. See Note 7—Debt.

Note 4—Unconsolidated Affiliates

~~Investments~~Equity investments—We hold noncontrolling equity investments in various ~~partially owned,~~ unconsolidated companies, ~~the most significant of which is a~~including (a) our 33.0 percent ownership interest in Orion Holdings (Cayman) Limited (together with its subsidiary, “Orion”), a Cayman Islands company that, through its wholly owned subsidiary, owns the harsh environment floater Transocean Norge~~. Additionally, we hold noncontrolling~~, and (b) our interests in certain companies that are involved in researching and developing technology to improve ~~operational~~ efficiency and reliability and to increase automation, sustainability and safety infor drilling and other activities. In the ~~six~~three months ended June 30, 2020, ~~and 2019,~~ we ~~made an~~recognized a loss of $59 million, which had no tax effect,

~~aggregate cash contribution of $6 million and $59 million, respectively, to Orion. In the three months ended June 30, 2020, we recognized a loss of $59 million, which had no tax effect,~~ recorded in other, net, associated with the impairment of our investment in Orion upon determination that the carrying amount of our ~~equity-method~~equity method investment exceeded the estimated fair value and that the impairment was other than temporary. We estimated the fair value of our investment using the income method, which required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including applying an assumed discount rate of 12 percent and making assumptions about the future performance of the investment, including future demand and supply for harsh environment floaters, rig utilization, revenue efficiency and dayrates. At June 30, ~~2020~~2021 and December 31, ~~2019,~~2020, the aggregate carrying amount of our ~~investment in Orion~~equity investments was ~~$106~~$139 million and ~~$164~~$138 million, respectively, recorded in other ~~assets.~~assets, of which the aggregate carrying amount of our equity investment in Orion was $105 million and $104 million, respectively.

Related party transactions—We engage in certain related party transactions with ~~Orion~~our unconsolidated affiliates, the most significant of which are under agreements with Orion. We have a management services agreement for the operation, stacking and maintenance of the harsh environment floater Transocean Norge and a marketing services agreement for the marketing of the rig. We also leased the rig under a short-term bareboat charter agreement, which expired in June 2021. Prior to the rig’s placement into service, we ~~also~~ engaged in certain related party transactions with Orion under a shipyard care agreement for the construction of the rig and other matters related to its completion and delivery. In the three and six months ended June 30, 2020, we received an aggregate cash payment of $26 million and $31 million, respectively, primarily related to the shipyard care agreement.

Additionally, in June 2021, Orion refinanced its shipyard loans under a financing arrangement for $100 million, in which we participated at a rate equivalent to our ownership interest in Orion. Borrowings under the financing arrangement are secured by Transocean Norge. The financing arrangement, which expires in June 2024, requires interest to be paid on outstanding borrowings at the London Interbank Offered Rate plus a margin of 6.50 percent per annum. In the three ~~and six~~ months ended June 30, ~~2019,~~2021, we ~~received an aggregate~~made a cash ~~payment~~investment in loans of ~~$20~~$33 million, and at June 30, 2021, the outstanding borrowings due to us under the financing arrangement were $33 million, ~~respectively, primarily related to the commissioning, preparation and mobilization of~~ ~~Transocean Norge~~ ~~under the shipyard care agreement. We also lease the rig under a short-term bareboat charter agreement, which is currently expected to expire~~recorded in ~~March 2021.~~other assets.

Note 5—Revenues

Overview—The duration of our performance obligation varies by contract. As of June 30, ~~2020,~~2021, the drilling contract with the longest expected remaining duration, excluding unexercised options, extends through February 2028. ~~To obtain contracts with our customers,~~In the three and six months ended June 30, 2021, we ~~incur~~recognized pre-operating costs ~~to prepare a rig for contract~~of $16 million and deliver or mobilize the rig to the drilling location. We defer such pre-operating costs and recognize the costs on a straight-line basis, consistent with the general pace of activity, in operating and maintenance costs over the estimated contract period.$30 million, respectively. In the three and six months ended June 30, 2020, we recognized pre-operating costs of $23 million and $32 million, respectively. ~~In the three and six months ended June 30, 2019, we recognized pre-operating costs of $3 million and $6 million, respectively.~~ At June 30, ~~2020~~2021 and December 31, ~~2019,~~2020, the carrying amount of our unrecognized pre-operating costs to obtain contracts was ~~$38~~$10 million and ~~$34~~$20 million, respectively, recorded in other assets.

In June 2020, we entered into a settlement and mutual release agreement with a customer, which provided for the final settlement of disputes related to performance obligations satisfied in prior periods. In connection with the settlement, among other things, our customer agreed to pay us $185 million in four equal installments through January 15, 2023. In the three and six months ended June 30, 2020, we recognized revenues of $177 million, representing the discounted value of the future payments, and recorded corresponding accounts receivable, net of imputed interest. At June 30, 2021 and ~~other assets~~December 31, 2020, the aggregate carrying amount of ~~$89~~the related receivable was $88 million and ~~$88~~$133 million, respectively, net of imputed interest, ~~which we will recognize~~including $45 million, recorded in ~~interest income over the scheduled payment period. In the six months ended June 30, 2019, we recognized revenues of $10~~accounts receivable, and $43 million ~~recognized on a cash basis, for performance obligations satisfied for another customer~~and $88 million, respectively, recorded in ~~prior periods.~~other assets.

Impairments of assets held and used—During the three months ended March 31, 2020, we identified indicators that the carrying amounts of our asset groups may not be recoverable. Such indicators included ~~recent~~ significant declines in commodity prices and the market value of our stock, a reduction of expected demand for our drilling services as our customers announced reductions of capital investments in response to commodity prices and a reduction of projected dayrates. As a result of our testing, we determined that the carrying amount of our midwater floater asset group was impaired. In the six months ended June 30, 2020, we recognized a loss of $31 million ($0.05 per diluted share), which had 0 tax effect, associated with the impairment of our midwater ~~floater.~~floater asset group. We measured the fair value of the drilling unit and related assets in this asset group by applying the market approach, using estimates of the exchange price that would be received for the assets in the principal or most advantageous markets for the assets in an orderly transaction between participants as of the measurement date. Our estimate of fair value required us to use significant other observable inputs, representative of Level 2 fair value measurements, including the marketability of the rig and prices of comparable rigs that may be sold for scrap value.

Impairments of assets held for sale—During the six months ended June 30, 2020, we announced our intent to sell or retire, in an environmentally responsible way, the ultra-deepwater floater GSF Development Driller II, the harsh environment floaters Polar Pioneer and Songa Dee and the midwater floaters Sedco 711,Sedco 714 and Transocean 712, along with related assets. In the three and six months ended June 30, 2020, we recognized an aggregate loss of $419 million ($420 million, or $0.68 per diluted share, net of tax) and $556 million ($0.90 per diluted share), which had 0 tax effect, respectively, associated with the impairment of these assets, which we determined were impaired at the time we classified the assets as held for sale. We measured the impairment of the drilling units and related assets 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 assets to be sold for scrap value or other purposes.

Dispositions—During the six months ended June 30, ~~2020,~~2021, in connection with our efforts to dispose of non-strategic assets, we completed the sale of the ~~midwater~~harsh environment floater ~~Sedco 714~~Leiv Eiriksson and related assets. In the six months ended June 30, ~~2020,~~2021, we received aggregate net cash proceeds of $4 million and recognized an aggregate net loss of $60 million ($0.10 per diluted share), which had 0 tax effect, associated with the disposal of these assets. In the six months ended June 30, 2020, we completed the sale of the midwater floater Sedco 714 and related assets, and we received aggregate net cash proceeds of $2 million associated with the disposal of these assets.

We intend to defend these lawsuits vigorously, although we can provide no assurance as to the outcome. We historically have maintained broad liability insurance, although we are not certain whether insurance will cover the liabilities, if any, arising out of these claims. Based on our evaluation of the exposure to date, we do not expect the liability, if any, resulting from these claims to have a material adverse effect on our condensed consolidated statement of financial position, results of operations or cash flows.

~~NaN~~One of our subsidiaries has been named as a defendant, along with numerous other companies, in lawsuits arising out of the subsidiary’s manufacture and sale of heat exchangers, and involvement in the construction and refurbishment of major industrial complexes alleging bodily injury or personal injury as a result of exposure to asbestos. As of June 30, ~~2020,~~2021, the subsidiary was a defendant in approximately ~~222~~281 lawsuits with a corresponding number of plaintiffs. For many of these lawsuits, we have not been provided sufficient information from the plaintiffs to determine whether all or some of the plaintiffs have claims against the subsidiary, the basis of any such claims, or the nature of their alleged injuries. The operating assets of the subsidiary were sold in 1989. In September 2018, the subsidiary and certain insurers agreed to a settlement of outstanding disputes that ~~leaves~~provided the subsidiary with ~~funding, including~~ cash ~~annuities~~ and an annuity.

nature. While we cannot predict or provide assurance as to the outcome of these matters, we do not expect the ultimate liability, if any, resulting from these claims to have a material adverse effect on our condensed consolidated statement of financial position, results of operations or cash flows.

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

Environmental matters

We have certain potential liabilities under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and similar state acts regulating cleanup of hazardous substances at various waste disposal sites, including those described below. CERCLA is intended to expedite the remediation of hazardous substances without regard to fault. Potentially responsible parties (“PRPs”) for each site include present and former owners and operators of, transporters to and generators of the substances at the site. It is difficult to quantify the potential cost of environmental matters and remediation obligations. Liability is strict and can be joint and several.

One of our subsidiaries was named as a PRP in connection with a site located in Santa Fe Springs, California, known as the Waste Disposal, Inc. site. We and other PRPs agreed, under a participation agreement with the U.S. Environmental Protection Agency (the “EPA”) and the U.S. Department of Justice, to settle our potential liabilities by remediating the site. The remedial action for the site was completed in 2006. Our share of the ongoing operating and maintenance costs has been insignificant, and we do not expect any additional potential liabilities to be material. Resolutions of other claims by the EPA, the involved state agency or PRPs are at various stages of investigation. Nevertheless, based on available information, we do not expect the ultimate liability, if any, resulting from all environmental matters and known potential legal claims that are likely to be asserted, to have a material adverse effect on our condensed consolidated statement of financial position, results of operations or cash flows.

Note 11—Equity

Share issuance—On June 14, 2021, we entered into an equity distribution agreement with a sales agent for the offer and sale of our shares, with up to a maximum aggregate net offering price of $400 million, pursuant to an at-the-market equity offering (the “ATM Program”). We intend to use the net proceeds from the ATM Program for general corporate purposes, which may include, among other things the repayment or refinancing of indebtedness and the funding of working capital, capital expenditures, investments and additional balance sheet liquidity. In the three months ended June 30, 2021, we received aggregate cash proceeds of $66 million, net of issue costs, for the aggregate sale of 15.2 million shares under the ATM Program. See Note 13—Subsequent Events.

Note ~~11—~~12—Financial Instruments

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


	June 30, 2020				December 31, 2019				June 30, 2021				December 31, 2020
	Carrying		Fair		Carrying		Fair		Carrying		Fair		Carrying		Fair

Long-term loans receivable from unconsolidated affiliates										35		31		2		2
Total debt										7,527		6,586		7,807		4,820

~~We estimated the fair value of each class of financial instruments by applying the following methods and assumptions:~~

Cash and cash equivalents—Our cash and cash equivalents are primarily invested in demand deposits, short-term time deposits and money market funds. The carrying amount of our cash and cash equivalents represents the historical cost, plus accrued interest, which approximates fair value because of the short maturities of the instruments.

Restricted cash and cash equivalents—Our restricted cash and cash equivalents, which are subject to restrictions due to collateral requirements, legislation, regulation or court order, are primarily invested in demand deposits ~~short-term time deposits~~ and money market funds. The carrying amount of our restricted cash and cash equivalents represents the historical cost, plus accrued interest, which approximates fair value because of the short maturities of the instruments.

~~Debt~~Long-term loans receivable from unconsolidated affiliates—The carrying amount of our long-term loans receivable from unconsolidated affiliates, recorded in other assets, represents the principal amount of the cash investment. We measured the estimated fair value of our long-term loans receivable from unconsolidated affiliates using significant unobservable inputs, representative of a Level 3 fair value measurement, including the terms and credit spreads for the instruments.

Total debt—The carrying amount of our total debt represents the principal amount, net of unamortized discounts, premiums, ~~debt~~ issue costs and fair value ~~adjustments.~~adjustments along with contractual interest payments of previously restructured debt. The carrying amount and fair value of our total debt includes amounts related to certain exchangeable debt instruments (see Note 7—Debt). We measured the estimated fair value of our total debt using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments.

Note 13—Subsequent Event

Share issuance—Subsequent to June 30, 2021, we received aggregate cash proceeds of $77 million, net of issue costs, for the aggregate sale of 16.5 million shares under the ATM Program.

Business

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, ~~“Transocean”,~~“Transocean,” “we,” “us” or “our”) is a leading international provider of offshore contract drilling services for oil and gas wells. As of July ~~23, 2020,~~27, 2021, we owned or had partial ownership interests in and operated 3937 mobile offshore drilling units, including 27 ultra-deepwater floaters and 1210 harsh environment floaters. As of July ~~23, 2020,~~27, 2021, we were constructing two ultra-deepwater drillships.

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 ultra-deepwater and harsh environment drilling services. Our drilling fleet is one of the most versatile fleets in the world, consisting of drillships and semisubmersible floaters used in support of offshore drilling activities and offshore support services on a worldwide basis.

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 operate, build or upgrade our rigs are determined by the activities and needs of our customers.

See “—Operating Results.”.

During the three months ended March 31, 2020, we identified indicators that the asset groups in our contract drilling services reporting unit may not be recoverable. As a result of our testing, we determined that the carrying amount of the remaining drilling rig and related assets in our midwater floater asset group was impaired. In the six months ended June 30, 2020, we recognized a loss of $31$60 million associated with the ~~impairment~~disposal of these ~~held and used~~ assets. See “—Operating ~~Results”~~Results.”

Outlook

Drilling market—~~During~~Over the latter part of 2019, the demand for our drilling services steadily increased and contract durations and dayrates substantially improved in all geographic market sectors. This momentum was interrupted, latelast several months we have observed a steady improvement in the ~~first quarter 2020,~~outlook for the global economic recovery and for oil and natural gas fundamentals and pricing. This improved outlook is supported by the delivery of effective vaccines, the deployment of economic ~~disruption~~stimulus packages, and the improving economic activities associated with a more confident stance on defeating the pandemic. We remain cautiously optimistic about the recovery of the global ~~COVID-19 pandemic~~economy, even in the context of emerging COVID variants, and can see the ~~significant decline~~path to pre-pandemic levels of ~~commodity prices spurred both by this pandemic and by production disputes among major oil producing countries, driving significant oversupply.~~

~~Since initiating efforts to mitigate the spread of COVID-19 many governments have begun to lift some of the restrictions on business and individual movement, and~~activity. We expect that demand for hydrocarbons ~~has begun~~may return to ~~improve, although it has still not recovered~~or exceed pre-pandemic levels within the next year or two.

As a result, many of our customers are now shifting their focus to ~~pre-pandemic levels. The~~increase exploration and production activities, and many previously delayed projects are again active. Offshore drilling activity is increasing in almost every ultra-deepwater market, ~~also~~and due to attrition of the global offshore fleet over the last several years, there are significantly fewer available drilling units and, particularly, an increasing scarcity of the highest specification drilling units as customers look to secure the best equipment for their projects. In the North Sea harsh environment market, an accelerated level of recovery is anticipated in 2022 through 2023 as the effect of Norway tax incentive programs is realized by our customers.

Considerable uncertainty remains about the speed of the global economic recovery and the associated demand for and supply of hydrocarbons, particularly with respect to prospective actions of the Organization of the Petroleum Exporting Countries. We believe that the rapid decline in ~~an oversupplied state~~production activities due to the ~~peak global~~ongoing pandemic, combined with the lack of investment in exploration and production activities over the past several years will precipitate substantial supply constraints that ~~coincided with a~~are not easily reversed without significant ~~reduction~~new investment in consumption. Additionally, the effects of COVID-19 continue to develop and change at a rapid pace. For instance, many countries that re-opened their economies beginning in the second quarter of 2020 have subsequently seen significant increases in the number of reported cases of COVID-19, causing governments to reimpose certain restrictions that had previously been lifted.drilling.

AsWith deepwater and harsh environment fields offering increasingly competitive returns, combined with their relatively low carbon intensity of production, we expect a ~~result,~~significant portion of required spending in fossil fuel development will be for deepwater and harsh environment projects. The restructuring and subsequent consolidation of many of our ~~customers have reduced capital expenditures~~competitors plus the accelerated retirement of units seen over the past several months and ~~delayed investment decisions for~~projected through the remainder of ~~2020 resulting in several previously sanctioned~~this year, should facilitate higher utilization of active assets and more efficient allocation of capital amongst restructured drilling contractors. In summary, our improving market dynamics combined with increasing demand for deepwater and harsh environment drilling have the potential to provide a materially better business environment for offshore ~~projects being either delayed or cancelled. These actions have an adverse impact on our near-term market outlook., reversing~~drillers that weathered the ~~positive trends experienced in 2019. It is currently unclear how long these reductions and delays will persist.~~

~~Longer term, as the negative~~ effects of ~~these global events eventually subside,~~the pandemic and ~~oil prices improve~~now move towards a more favorable outlook for 2022 and stabilize, we believe the prospects of the offshore drilling floater market will significantly improve, especially for the highest specification vessels. The structural efficiency gains achieved by the offshore oil and gas industry in the past six years have materially improved the economics of offshore development projects, and we believe such efficiency gains will make these projects attractive again when the commodity prices sufficiently recover from the current levels.beyond.

Fleet status—We refer to the availability of our rigs in terms of the uncommitted fleet rate. The uncommitted fleet rate is defined as the number of uncommitted days divided by the total number of rig calendar days in the measurement period, expressed as a percentage. An uncommitted day is defined as a calendar day during which a rig is idle or stacked, is not contracted to a customer and is not committed to a shipyard. The uncommitted fleet rates exclude the effect of priced options. As of July ~~15, 2020,~~21, 2021, the uncommitted fleet rates for the remainder of ~~2020~~2021 and each of the four years in the period ending December 31, ~~2024~~2025 were as follows:


	2020		2021		2022		2023		2024		2021		2022		2023		2024		2025
Uncommitted fleet rate
Ultra-deepwater floaters	47	%	67	%	84	%	83	%	83	%	49	%	66	%	76	%	83	%	83	%
Harsh environment floaters	35	%	51	%	63	%	80	%	98	%	45	%	42	%	76	%	98	%	100	%

Performance and Other Key Indicators

Contract backlog—Contract backlog is defined as the maximum contractual operating dayrate multiplied by the number of days remaining in the firm contract period, excluding revenues for mobilization, demobilization, contract preparation, other incentive provisions or reimbursement revenues, which are not expected to be significant to our contract drilling revenues. The contract backlog represents the maximum contract drilling revenues that can be earned considering the contractual operating dayrate in effect during the firm contract period. The contract backlog for our fleet was as follows:


	July 15,		April 16,		February 14,		July 21,		April 28,		February 12,
	2020		2020		2020		2021		2021		2021

Contract backlog	(In millions)						(In millions)
Ultra-deepwater floaters	$	6,487	$	6,936	$	7,282	$	5,706	$	5,638	$	5,911
Harsh environment floaters		2,403		2,662		2,836		1,639		1,765		1,931
Midwater floaters		—		—		45
Total contract backlog	$	8,890	$	9,598	$	10,163	$	7,345	$	7,403	$	7,842

We believe our industry-leading contract backlog sets us apart from the competition. Our contract backlog includes only firm commitments, 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 contracted newbuild unit that is currently under construction but excludes amounts related to the conditional agreement we have for our second newbuild unit 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.

The COVID-19 pandemic and ~~the~~ volatility ~~in oil prices in the first half of 2020, which have included precipitous drops~~ in oil prices could have significant adverse consequences for the financial condition of our customers. This ~~may~~could result in contract cancellations, early terminations, customers seeking price reductions or more favorable economic terms, a reduced ability to ultimately collect receivables, or entry into lower dayrate contracts or having to idle, stack or retire more of our rigs.

Average daily revenue—Average daily revenue is defined as contract drilling revenues, excluding revenues for contract terminations, reimbursements and contract intangible amortization, 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. The average daily revenue for our fleet was as follows:

Our average daily revenue fluctuates relative to market conditions and our revenue efficiency. The average daily revenue may be affected by revenues for lump sum bonuses or demobilization fees received from our customers. Our total fleet average daily revenue is also affected by the mix of rig classes being operated, as ~~deepwater floaters,~~ midwater floaters ~~and high-specification jackups~~ are typically contracted at lower dayrates compared to ultra-deepwater floaters and harsh environment floaters. We no longer operate ~~deepwater floaters,~~ midwater ~~floaters or high-specification jackups.~~floaters. We include newbuilds in the calculation

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

Revenue efficiency measures our ability to ultimately convert our contractual opportunities into revenues. Our revenue efficiency rate varies due to revenues earned under alternative contractual dayrates, such as a waiting on weather rate, repair rate, standby rate, force majeure rate or zero rate, that may apply under certain circumstances. Our revenue efficiency rate is also affected by incentive performance bonuses or penalties. We include newbuilds in the calculation when the rigs commence operations upon acceptance by the customer. We exclude rigs that are not operating under contract, such as those that are stacked.

Rig utilization—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. The rig utilization rates for our fleet were as follows:


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

Total fleet average rig utilization	66	%	60	%	56	%	55	%	53	%	66	%

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 or classification as held for sale. Accordingly, our rig utilization can increase when idle or stacked units are removed from our drilling fleet.

Contract drilling revenues—Contract drilling revenues ~~increased~~decreased for the three months ended June 30, ~~2020,~~2021, compared to the three months ended June 30, ~~2019,~~2020, primarily due to the following: (a) ~~$177~~approximately $200 million resulting from the settlement of disputes and payments for early termination of a contract in the three months ended June 30, 2020 with no comparable activity in the current-year period, (b) approximately ~~$35~~$65 million resulting from ~~the reactivations of two ultra-deepwater floaters in Brazil,~~rigs that were cold stacked, (c) approximately $25 million resulting from ~~a harsh environment floater that we placed into service in August 2019 and~~rigs sold, (d) approximately ~~$21~~$10 million resulting from ~~the early termination~~higher idle or out of ~~a contract~~service days for the ~~convenience of a customer.~~active fleet and (e) approximately $5 million due to lower customer reimbursables related to COVID-19. These ~~increases~~decreases were partially offset by the following ~~decreases:~~increases: (a) ~~approximately $70 million resulting from lower activity and (b)~~ approximately $20 million resulting from ~~rigs sold or classified as held for sale.~~an increased average daily revenue and (b) approximately $5 million resulting from higher revenue efficiency.

Costs and expenses—Operating and maintenance costs and expenses ~~increased~~decreased for the three months ended June 30, ~~2020,~~2021, compared to the three months ended June 30, ~~2019,~~2020, primarily due to the following: (a) approximately ~~$30~~$40 million resulting from rigs that were cold stacked, (b) approximately $30 million of litigation and settlement costs recognized in the prior-year period, (c) approximately $25 million resulting from rigs sold, (d) approximately $20 million resulting from reduced onshore personnel costs, including severance and (e) approximately $15 million resulting from reduced offshore personnel and related costs associated with our mitigation efforts of the COVID-19 pandemic, (b) $30 million resulting from litigation and settlement costs, (c) approximately $25 million resulting from the operations of the harsh environment floater that we placed into service in August 2019, (d) approximately $10 million resulting from offshore and onshore severance costs and (e) approximately $10 million resulting from the reactivations of two ultra-deepwater floaters in Brazil.pandemic. These ~~increases~~decreases were partially offset by the following ~~decreases:~~increases: (a) ~~approximately $45 million resulting from reduced shipyard costs and delayed in-service maintenance costs, (b) approximately $25 million resulting from rigs now stacked or idle and (c)~~ approximately $20 million resulting from ~~rigs sold or classified as held for sale.~~shipyard and maintenance costs driven by current in-service and out-of-service activities and (b) approximately $20 million resulting from unfavorable exchange rates.

Depreciation and amortization expense decreased for the three months ended June 30, ~~2020,~~2021, compared to the three months ended June 30, ~~2019,~~2020, primarily due to ~~$20~~$5 million resulting from rigs sold or classified as held for sale ~~subsequent to June 30, 2019.~~and $5 million resulting from assets that had reached the end of their useful lives or had been retired.

Loss on impairment ~~of assets~~—In the three months ended June 30, 2020, we recognized a loss on ~~the~~ impairment of assets, including an aggregate net loss of $419 million associated with assets that we determined were impaired at the time we classified them as held for sale.

Other income and expense—Interest expense, net of amounts capitalized, decreased in the three months ended June 30, ~~2020,~~2021, compared to the three months ended June 30, ~~2019,~~2020, primarily due to ~~a decrease of $34~~the following: (a) $26 million resulting from our debt restructuring in August and September 2020 and (b) approximately $16 million resulting from debt repaid as scheduled or retired ~~or repaid, including the full~~early in our open market repurchases, redemption ~~of the 9.00% Senior Notes in February~~and cash tender offers subsequent to January 1, 2020, partially offset by ana net increase of ~~$19~~(c) $4 million resulting from private debt ~~issued, including~~exchanges completed in February 2021.

Other income, net, increased in the ~~8.00% Senior Notes in January 2020 and the 5.375% senior secured notes due May 2023 (the “5.375% Senior Secured Notes”) in May 2019.~~

Inthree months ended June 30, 2021, compared to the three months ended June 30, 2020, weprimarily due to (a) a loss of $59 million recognized ~~an aggregate net gain of $4 million~~in the prior-year period associated with the ~~retirement of $21 million aggregate principal amount~~impairment of our ~~debt securities repurchased~~equity investment in ~~the open market.

~~we recognized an aggregate net loss of $9 million resulting from the retirement of $130 million aggregate principal amount of our debt securities repurchased in the open market.~~

Other expense, net, increased in the three months ended June 30, 2020, compared to the three months ended June 30, 2019, primarily due to the following: (a) a loss of $59 million associated with the impairment of our equity-method investment in Orion, (b) net increased loss of $10 million resulting from currency exchange rates and (c) a gain of $10 million recognized in the prior-year period resulting from the bargain purchase of Ocean Rig UDW Inc. (“Ocean Rig”), completed in the year ended December 31, 2018.

Income tax expense—In the three months ended June 30, ~~2020~~2021 and ~~2019,~~2020, our effective tax rate was ~~(6.8)~~(4.6) percent and ~~(21.9)~~(6.8) percent, respectively, based on loss before income tax expense. In the three months ended June 30, ~~2020~~2021 and ~~2019,~~2020, the effect of various discrete period tax items was a net tax ~~expense~~benefit of ~~$11~~$6 million and a net tax ~~benefit~~expense of $5$11 million, respectively. In the three months ended June 30, 2021, such discrete items included expiration and settlements of various uncertain tax positions. In the three months ended June 30, 2020, such discrete items included ~~the~~ revenues recognized for the settlement of disputes, ~~the~~ loss on impairment of investment in an unconsolidated affiliate, certain return to provision adjustments, withholding tax accruals, gains and losses on currency exchange rates and changes to valuation allowances. In the three months ended June 30, ~~2019, such discrete items included settlements of various uncertain tax positions, partially offset by changes in the valuation allowance related to deferred tax assets~~2021 and ~~adjustments to our deferred taxes for operating structural changes made in the U.S. In the three months ended June 30,~~ 2020, ~~and 2019,~~ our effective tax rate, excluding discrete items, was ~~(15.0)~~(10.2) percent and ~~(25.4)~~(15.0) percent, respectively, based on loss before income tax expense.

Due to our operating activities and organizational structure, our income tax expense does not change proportionally with our income before income taxes. Significant decreases in our income before income taxes typically lead to higher effective tax rates, while significant increases in income before income taxes can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above. With respect to the effective tax rate calculation for the three months ended June 30, ~~2020,~~2021, 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 and India. Conversely, the countries in which we incurred the most significant income taxes during this period that were based on income before income tax include ~~Brazil, Canada,~~ the U.S., Switzerland, Norway and ~~the U.K.~~Brazil. Our rig operating structures further complicate our tax calculations, especially in instances where we have more than one operating structure for the taxing jurisdiction and, thus, more than one method of calculating taxes depending on the operating structure utilized by the rig under the contract.

Sources and uses of liquidity

Overview—We expect to use existing unrestricted cash balances, internally generated cash flows, borrowings under the Secured Credit Facility, proceeds from the disposal of assets or proceeds from the issuance of additional debt or equity to fulfill anticipated obligations, which may include capital expenditures, working capital and other operational requirements, scheduled debt maturities or other payments. We may ~~also~~ consider establishing additional financing arrangements with banks or other capital ~~providers. Additionally, at our 2020 annual general meeting, our shareholders approved a proposal to amend our Articles of Association to increase the total number of~~providers or issuing shares ~~that may be issued using~~from our authorized share ~~capital to a maximum of approximately 185.0 million shares, representing approximately 30 percent of our issued shares as of March 10, 2020.~~capital. Subject to market conditions and other factors, we may ~~also~~ be required to provide collateral for any future financing arrangements. We continue to evaluate additional potential liability management transactions in connection with our ongoing efforts to prudently manage our capital structure and improve our liquidity. In each case subject to then existing market conditions and our expected liquidity needs, among other factors, we may continue to use existing unrestricted cash balances, internally generated cash flows and proceeds from asset sales to pursue liability management transactions, including among others, purchasing or exchanging one or more existing series of our debt securities in the open market, in privately negotiated transactions, through tender offers or through exchange offers. Any future purchases, exchanges or other transactions may be on the same terms or on terms that are more or less favorable to holders than the terms of any prior transaction, including the exchange transactions completed in the year ended December 31, 2020 and in February 2021. We can provide no assurance as to which, if any, of these alternatives, or combinations thereof, we may choose to pursue in the future, if at all, or as to the timing with respect to any future transactions.

future financing arrangements. In each case subject to then existing market conditions and to our expected liquidity needs, among other factors, we may continue to use a portion of our cash on hand, internally generated cash flows and proceeds from asset sales to reduce debt prior to scheduled maturities through debt repurchases, either in the open market or in privately negotiated transactions, or through debt redemptions or tender offers.

The ~~effects~~ongoing effect of the COVID-19 pandemic, including the impact of virus variants, and the volatility ~~and declines~~ in oil prices ~~in the first half of 2020~~ could have significant adverse consequences for general economic, financial and business conditions, as well as for our business and financial position and the business and financial position of our customers and suppliers and may, among other things, impact our ability to generate cash flows from operations, access the capital markets on acceptable terms or at all, and affect our future need or ability to borrow under our Secured Credit Facility. In addition to our potential sources of funding, the effects of such global events may impact our liquidity or need to alter our allocation or sources of capital, implement further cost reduction measures and change our financial strategy. Although the COVID-19 pandemic and the volatility ~~and declines~~ in oil prices ~~in the first half of 2020~~ could have a broad range of effects on our sources and uses of liquidity, the ultimate effect thereon, if any, will depend on future developments, which cannot be predicted at this time.

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, industry conditions, general economic conditions, market conditions and market perceptions of us and our industry. The rating of our non-credit enhanced senior unsecured long-term debt (“Debt Rating”) is below investment grade. Such Debt Rating has caused us to experience increased fees and interest rates under agreements governing certain of our senior notes. Further downgrades may affect or limit our ability to access debt markets in the future. 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 like the one we are currently experiencing 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.

Our internally generated cash flows are directly related to our business and the market sectors in which we operate. We have generated positive cash flows from operating activities over recent years and, although we cannot provide assurances, we currently expect that such cash flows will continue to be positive over the next year. However, among other factors, if the drilling market deteriorates, or if we experience poor operating results, or if we incur expenses to, for example, reactivate, stack or otherwise assure the marketability of our fleet, cash flows from operations may be reduced or negative.

Our ability and willingness to access the debt and equity markets is a function of a variety of factors, including, among others, general economic conditions, industry conditions, market conditions and market perceptions of us and our industry and credit rating agencies’ views of our debt. The rating of the majority of our long-term debt (“Debt Rating”) is below investment grade. The Debt Rating is causing us to experience increased fees and interest rates under our Secured Credit Facility and agreements governing certain of our senior notes. Future downgrades may further restrict our ability to access the debt market for sources of capital and may negatively impact the cost of such capital at a time when we would like, or need, to access such markets, which could have an impact on our flexibility to react to changing economic and business conditions. An economic downturn like the one we are currently experiencing 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.

Secured Credit Facility—We have a $1.3 billion secured revolving credit facility established under a bank credit agreement as(as amended ~~most recently in December 2019 (the~~from time to time, the “Secured Credit Facility”), which is scheduled to expire on June 22, 2023. The Secured Credit Facility is guaranteed by Transocean Ltd. and certain subsidiaries. The Secured Credit Facility is secured by, among other things, a lien on the ultra-deepwater floaters Deepwater Asgard, Deepwater Corcovado, Deepwater Invictus, Deepwater Mykonos, Deepwater Orion, Deepwater Skyros, Development Driller III, Dhirubhai Deepwater KG2 and Discoverer Inspiration and the harsh environment floaters Transocean Barents and Transocean Spitsbergen. The maximum borrowing capacity will be reduced to $1.0 billion if, and so long as, our leverage ratio, measured as the aggregate principal amount of debt outstanding to earnings before interest, taxes, depreciation and amortization, exceeds 10.00 to 1.00. The Secured Credit Facility contains covenants that, among other things, include maintenance of certain guarantee and collateral coverage ratios, a maximum debt to capitalization ratio of 0.60 to 1.00 and minimum liquidity of $500 million. The Secured Credit Facility also restricts the ability of Transocean Ltd. and certain of our subsidiaries to, among other things, merge, consolidate or otherwise make changes to the corporate structure, incur liens, incur additional indebtedness, enter into transactions with affiliates and pay dividends and other distributions. In order to borrow under the Secured Credit Facility, we must, at the time of the borrowing request, not be in default under the Secured Credit Facility and make certain representations and warranties, including with respect to compliance with laws and solvency, to the lenders. Repayment of borrowings under the Secured Credit Facility are subject to acceleration upon the occurrence of an event of default. Under the agreements governing certain of our debt and finance lease, we are also subject to various covenants, including restrictions on creating liens, engaging in sale/leaseback transactions and engaging in certain merger, consolidation or reorganization transactions. A default under our public debt indentures, the agreements governing our senior secured notes, our finance lease contract or any other debt owed to unaffiliated entities that exceeds $125 million could trigger a default under the Secured Credit Facility and, if not waived by the lenders, could cause us to lose access to the Secured Credit Facility. At July ~~23, 2020,~~27, 2021, we had no borrowings outstanding, ~~$21~~$23 million of letters of credit issued, and we had $1.3 billion of available borrowing capacity under the Secured Credit Facility.

Shipyard financing arrangement—In June 2021, we and Jurong Shipyard Pte Ltd. entered into the Shipyard Loans to finance the final payments expected to be owed to the shipyard upon delivery of the ultra-deepwater floaters Deepwater Atlas and Deepwater Titan. We expect to borrow approximately $370 million upon delivery of Deepwater Atlas in December 2021, and we expect to borrow approximately $90 million upon delivery of Deepwater Titan in the three months ending June 30, 2022. The Shipyard Loans will be guaranteed by Transocean Inc. Borrowings under the Shipyard Loan for Deepwater Atlas are expected to be secured by, among other security, a lien on the rig. In certain circumstances, the maximum aggregate borrowing capacity under the Shipyard Loan for Deepwater Titan may be increased to approximately $440 million, and such Shipyard Loan may become secured by, among other security, a lien on the rig. We will repay the borrowings, together with interest of 4.5 percent per annum, according to the selected installment schedule with a maximum of a six-year period following delivery of the drilling rigs. We will have the right to prepay any outstanding borrowings, in full or in part, without penalty. The Shipyard Loans contain customary events of default and affirmative and negative covenants, including covenants limiting the ability of the subsidiary owners of the drilling rigs from incurring certain types of additional indebtedness or making certain additional commitments or investments. At July 27, 2021, we had no borrowings outstanding under the Shipyard Loans.

Share issuance—On June 14, 2021, we entered into an equity distribution agreement with a sales agent for the offer and sale of our shares, with up to an aggregate net offering price of $400 million, pursuant to the ATM Program. We intend to use the net proceeds from the sale of our shares under the ATM Program for general corporate purposes, which may include, among other things the repayment

The indenture that governs the 4.00% Senior Guaranteed Exchangeable Bonds also requires such bonds to be repurchased upon the occurrence of certain fundamental changes and events, at specified prices depending on the particular fundamental change or event, which include changes and events related to certain (i) change of control events applicable to Transocean Ltd. or Transocean Inc., (ii) the failure of our shares to be listed or quoted on a national securities exchange and (iii) specified tax matters. The 4.00% Senior Guaranteed Exchangeable Bonds may be exchanged at any time prior to the close of business on the second business day immediately preceding the maturity date at a current exchange rate of 190.4762 Transocean Ltd. shares per $1,000 note, which implies an exchange price of $5.25 per share, subject to adjustment upon the occurrence of certain events, and any such exchange may be settled in cash, Transocean Ltd. shares or a combination of cash and Transocean Ltd. shares, at our election.

On August 14, 2020, we issued $238 million aggregate principal amount of 2.50% Senior Guaranteed Exchangeable Bonds in privately negotiated exchange transactions for $397 million aggregate principal amount of the 0.50% Exchangeable Senior Bonds. The 2.50% Senior Guaranteed Exchangeable Bonds are fully and unconditionally guaranteed by Transocean Ltd. and certain wholly owned indirect subsidiaries of Transocean Inc. We may redeem all or a portion of the 2.50% Senior Guaranteed Exchangeable Bonds (i) on or after August 14, 2022, if certain conditions related to the price of our shares have been satisfied, at a price equal to 100 percent of the aggregate principal amount and (ii) on or after August 14, 2023, at specified redemption prices. The indenture that governs the 2.50% Senior Guaranteed Exchangeable Bonds contains covenants that, among other things, limit our ability to incur certain liens on our drilling units without equally and ratably securing the notes, engage in certain sale and lease back transactions covering any of our drilling units, allow our subsidiaries to incur certain additional debt, and consolidate, merge or enter into a scheme of arrangement qualifying as an amalgamation. The indenture that governs the 2.50% Senior Guaranteed Exchangeable Bonds also requires such bonds to be repurchased upon the occurrence of certain fundamental changes and events, at specified prices depending on the particular fundamental change or event, which include changes and events related to certain (i) change of control events applicable to Transocean Ltd. or Transocean Inc., (ii) the failure of our shares to be listed or quoted on a national securities exchange and (iii) specified tax matters. The 2.50% Senior Guaranteed Exchangeable Bonds may be exchanged at any time prior to the close of business on the second business day immediately preceding the maturity date or the redemption date at a current exchange rate of 162.1626 Transocean Ltd. shares per $1,000 note, which implies an exchange price of $6.17 per share, subject to adjustment upon the occurrence of certain events.

We may redeem all or a portion of the 11.50% Senior Guaranteed Notes prior to July 30, 2023 at a price equal to 100 percent of the aggregate principal amount plus a make-whole premium, and subsequently, at specified redemption prices. We may also use the net cash proceeds of certain equity offerings by Transocean Ltd. to redeem, on one or more occasions prior to July 30, 2023, up to a maximum of 40 percent of the original aggregate principal amount of the 11.50% Senior Guaranteed Notes, subject to certain adjustments, at a redemption price equal to 111.50 percent of the aggregate principal amount.

Decisions regarding the amount, if any, and timing of any share repurchases will be made from time to time based on these factors. Any repurchased shares under the share repurchase program would be held by us for cancellation by the shareholders at a future general meeting of shareholders.

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, new rig construction, or the acquisition of a rig under construction. We may commit to such investment without first obtaining customer contracts. Any 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.

Deepwater Titan is an ultra-deepwater drillship under construction at the Jurong Shipyard Pte Ltd. in ~~Singapore,~~Singapore. We currently expect that the shipyard will be ready to deliver Deepwater Titan in the second quarter of 2022, and upon delivery, we expect to borrow approximately $90 million under the Shipyard Loan to finance the final installment to the shipyard (see “—Sources and uses of liquidity”). The rig is expected to commence operations under its drilling contract in the first half of ~~2022.~~2023. The projected capital additions include estimates for an upgrade for two 20,000 pounds per square inch blowout preventers and other equipment required by our customer.

The ultimate amount of our capital expenditures is partly dependent upon financial market conditions, the actual level of operational and contracting activity, the costs associated with the current regulatory environment and customer requested capital improvements and equipment for which the customer agrees to reimburse us. As with any major shipyard project that takes place over an extended period of time, the actual costs, the timing of expenditures and the project completion date may vary from estimates based on numerous factors, including actual contract terms, weather, exchange rates, shipyard labor conditions, availability of suppliers to recertify equipment and the market demand for components and resources required for drilling unit construction. We intend to fund the cash requirements relating to our capital expenditures ~~through~~not financed under the Shipyard Loans by using available cash balances, cash generated from operations and asset sales, borrowings under our Secured Credit Facility and financing arrangements with banks or other capital providers. ~~We also have available credit under our Secured Credit Facility (see “—Sources~~Economic conditions and ~~uses of liquidity”). Economic conditions~~other factors could impact the availability of these sources of funding. See “—Sources and uses of liquidity.”

Dispositions—From time to time, we may also review the possible disposition of ~~non-strategic~~certain drilling ~~units.~~assets. Considering market conditions, we have committed to plans to sell certain lower-specification drilling units for scrap value. During the six months ended June 30, 2020 and the year ended December 31, 2019, we identified six such drilling units, respectively, that we have sold or intend to sell for scrap value or other purposes. During the six months ended June 30, 2020,2021, we completed the sale of one ~~midwater~~harsh environment floater ~~along with~~and related assets, and we received net cash proceeds of $2$4 million. During the year ended December 31, ~~2019,~~2020, we completed the sale of ~~six~~one ultra-deepwater ~~floaters, one~~floater, three harsh environment ~~floater, two deepwater~~ floaters and ~~two~~three midwater floaters, along with related assets, and we received aggregate net cash proceeds of ~~$64~~$20 million. We continue to evaluate the drilling units in our fleet and may identify additional ~~lower specification~~lower-specification drilling units to be sold for scrap value.

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. We disclose our significant accounting policies 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, 2020. For a discussion of the new accounting standards updates 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—Accounting Standards Update in this quarterly report on Form 10-Q.

Tax matters

We conduct operations through our various subsidiaries in countries throughout the world. Each country has its own tax regimes with varying nominal rates, deductions and tax attributes. From time to time, we may identify changes to previously evaluated tax positions that could result in adjustments to our recorded assets and liabilities. Although we are unable to predict the outcome of these changes, we do not expect the effect, if any, resulting from these adjustments to have a material adverse effect on our condensed consolidated ~~statement of~~ financial position, results of operations or cash flows. We file federal and local tax returns in several jurisdictions throughout the world. Tax authorities in certain jurisdictions are examining our tax returns and, in some cases, have issued assessments. We ~~are defending~~intend to defend our tax positions ~~in those jurisdictions. While~~vigorously, although we ~~cannot predict or~~can provide no assurance as to the ~~final outcome of these proceedings, we~~outcome.

Quantitative and Qualitative Disclosures About Market Risk

Overview—We are exposed to interest rate risk, primarily associated with our long-term debt, including current maturities.
