RISK FACTORS

An investment in the Company and TINC involves risks. Before making an investment decision with respect to the Compulsory Acquisition and the Company, investors should carefully consider the risk factors and all information contained in this Prospectus, including the financial statements and related notes incorporated herein by reference. The risks and uncertainties described in this section are the principal known risks and uncertainties faced by the Group as of the date hereof that the Company believes are material to an investment in the Company. The absence of negative past experience associated with any given risk does not mean that the risks and uncertainties described herein should not be considered prior to making an investment decision in respect of the Company. If any of the following risks were to materialize, individually or together with other circumstances, they could have a material and adverse effect on the Group or its business, financial condition, results of operations, cash flows or prospects, which could cause a decline in the value and trading price of the Shares, the Existing Exchangeable Bonds and/or New Exchangeable Bonds, resulting in the loss of all or part of an investment in the same. The order in which the risks are presented does not reflect the likelihood of their occurrence or the magnitude of their potential impact on the Group’s business, financial condition, results of operations, cash flows or prospects.

Risks Related to the Business of the Group

The Group’s drilling contracts may be terminated due to a number of events, and, during depressed market conditions, the Group’s customers may seek to repudiate or renegotiate their contracts

Certain of the Group’s drilling contracts with customers may be cancellable at the option of the customer upon payment of an early termination payment. Such payments may not, however, fully compensate the Group for the loss of the contract. Drilling contracts also customarily provide for either automatic termination or termination at the option of the customer typically without the payment of any termination fee, under various circumstances such as non-performance, as a result of significant downtime or impaired performance caused by equipment or operational issues, or sustained periods of downtime due to force majeure events. Many of these events are beyond the Group’s control. During periods of depressed market conditions, the Group is subject to an increased risk of the Group’s customers seeking to repudiate their contracts, including through claims of non-performance.  The Group is at continued risk of experiencing early contract terminations in the current weak commodity price environment as operators look to reduce their capital expenditures. During the years ended December 31, 2017, 2016 and 2015, the Transocean Group’s customers early terminated or cancelled contracts for one, eight and five of the Transocean Group’s rigs, respectively, and these rigs currently remain idle. The Transocean Group’s customers’ ability to perform their obligations under their drilling contracts, including their ability to fulfill their indemnity obligations to the Group, also may be negatively impacted by an economic downturn. The Group’s customers, which include national oil companies, often have significant bargaining leverage over the Group. If customers cancel some of the Group’s contracts, and the Group is unable to secure new contracts on a timely basis and on substantially similar terms, or if contracts are suspended for an extended period of time or if a number of the contracts are renegotiated, it could adversely affect the Group’s consolidated statement of financial position, results of operations or cash flows.

The Group’s current backlog of contract drilling revenue may not be fully realized, which may have a material adverse impact on the Group’s consolidated statement of financial position, results of operations or cash flows

At October 26, 2017, the Transocean Group’s contract backlog was approximately USD 9.4 billion. This amount represents the firm term of the drilling contract multiplied by the contractual operating rate, which may be higher than the actual day rate the Group receives or the Group may receive other day rates included in the contract, such as waiting on weather rate, repair rate, standby rate or force majeure rate. The contractual operating day rate may also be higher than the actual day rate the Group receives because of a number of factors, including rig downtime or suspension of operations.

Several factors could cause rig downtime or a suspension of operations, including:

In certain drilling contracts, the day rate may be reduced to zero or result in customer credit against future day rate if, for example, repairs extend beyond a stated period of time. The Group’s contract backlog includes signed drilling contracts and, in some cases, other definitive agreements awaiting contract execution. The Group may not be able to realize the full amount of the Group’s contract backlog due to events beyond the Group’s control. In addition, some of the Group’s customers have experienced liquidity issues in the past and these liquidity issues could be experienced again if commodity prices decline to lower levels for an extended period of time. Liquidity issues and other market pressures could lead the Group’s customers to go into bankruptcy or could encourage the Group’s customers to seek to repudiate, cancel or renegotiate these agreements for various reasons (see above “—The Group’s drilling contracts may be terminated due to a number of events, and, during depressed market conditions, the Group’s customers may seek to repudiate or renegotiate their contracts”). The Group’s inability to realize the full amount of the Group’s contract backlog may have a material adverse effect on the Group’s consolidated statement of financial position, results of operations or cash flows.

The Group’s operating and maintenance costs will not necessarily fluctuate in proportion to changes in the Group’s operating revenues

The Group’s operating and maintenance costs will not necessarily fluctuate in proportion to changes in the Group’s operating revenues. Costs for operating a rig are generally fixed or only semi-variable regardless of the day rate being earned. In addition, should the Group’s rigs incur unplanned downtime while on contract or idle time between drilling contracts, the Group will not always reduce the staff on those rigs because the Group

could use the crew to prepare the rig for its next contract. During times of reduced activity, costs reductions may not be immediate because portions of the crew may be required to prepare rigs for stacking, after which time the crew members may be assigned to active rigs or released. As the Group’s rigs are mobilized from one geographic location to another, the labor and other operating and maintenance costs can vary significantly. In general, labor costs increase primarily due to higher salary levels and inflation. Equipment maintenance costs fluctuate depending upon the type of activity the unit is performing and the age and condition of the equipment, and these costs could increase for short or extended periods as a result of regulatory or customer requirements that raise maintenance standards above historical levels. Contract preparation costs vary based on the scope and length of contract preparation required and the duration of the firm contractual period during which such expenditures are amortized.

The Group’s business involves numerous operating hazards, and the Group’s insurance and indemnities from its customers may not be adequate to cover potential losses from the Group’s operations

The Group’s operations are subject to the usual hazards inherent in the drilling of oil and gas wells, such as, blowouts, reservoir damage, loss of production, loss of well control, lost or stuck drill strings, equipment defects, craterings, fires, explosions and pollution. Contract drilling requires the use of heavy equipment and exposure to hazardous conditions, which may subject the Group to liability claims by employees, customers and other parties. These hazards can cause personal injury or loss of life, severe damage to or destruction of property and equipment, pollution or environmental damage, claims by third parties or customers and suspension of operations. The Group’s offshore fleet is also subject to hazards inherent in marine operations, either while on site or during mobilization, such as capsizing, sinking, grounding, collision, piracy, damage from severe weather and marine life infestations.

The South China Sea, the Northwest Coast of Australia and the U.S. Gulf of Mexico area are subject to typhoons, hurricanes or other extreme weather conditions on a relatively frequent basis, and the Group’s drilling rigs in these regions may be exposed to damage or total loss by these storms, some of which may not be covered by insurance. The occurrence of these events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury to or death of rig personnel. Some experts believe global climate change could increase the frequency and severity of these extreme weather conditions. Operations may also be suspended because of machinery breakdowns, abnormal drilling conditions, subcontractors’ failure to perform or supply goods or services, or personnel shortages. The Group customarily provides contract indemnity to the Group’s customers for certain claims that could be asserted by the Group relating to damage to or loss of the Group’s equipment, including rigs, and claims that could be asserted by the Group or the Group’s employees relating to personal injury or loss of life.

Damage to the environment could also result from the Group’s operations, particularly through spillage of hydrocarbons, fuel, lubricants or other chemicals and substances used in drilling operations, or extensive uncontrolled fires. The Group may also be subject to property damage, environmental indemnity and other claims by oil and natural gas companies. Drilling involves certain risks associated with the loss of control of a well, such as blowout, cratering, the cost to regain control of or re-drill the well and remediation of associated pollution. The Group’s customers may be unable or unwilling to indemnify the Group against such risks. In addition, a court may decide that certain indemnities in the Group’s current or future drilling contracts are not enforceable. The law generally considers contractual indemnity for criminal fines and penalties to be against public policy, and the enforceability of an indemnity as to other matters may be limited.

The Group’s insurance policies and drilling contracts contain rights to indemnity that may not adequately cover the Group’s losses, and the Group does not have insurance coverage or rights to indemnity for all risks. The Group has two main types of insurance coverage: (1) hull and machinery coverage for physical damage to the Group’s property and equipment and (2) excess liability coverage, which generally covers offshore risks, such as personal injury, third-party property claims, and third-party non-crew claims, including wreck removal and pollution. The Group generally has no hull and machinery insurance coverage for damages caused by named storms in the U.S. Gulf of Mexico. The Group maintains per occurrence deductibles that generally range up to USD 10 million for various third-party liabilities and an additional aggregate annual deductible of USD 50 million, which is self-insured through the Group’s wholly owned captive insurance company. The Group also retains the risk for any liability exceeding the Group’s USD 750 million excess liability coverage. However, pollution and environmental risks generally are not completely insurable. Additionally, the Company generally does not carry insurance for loss of revenue, except as required under certain debt agreements.

If a significant accident or other event occurs that is not fully covered by the Group’s insurance or by an enforceable or recoverable indemnity, the occurrence could adversely affect the Group’s consolidated statement of financial position, results of operations or cash flows. The amount of the Group’s insurance may also be less than the related impact on enterprise value after a loss. The Group’s insurance coverage will not in all situations provide sufficient funds to protect the Group from all liabilities that could result from its drilling operations. The Group’s coverage includes annual aggregate policy limits. As a result, the Group generally retains the risk for any losses in excess of these limits. The Group generally does not carry insurance for loss of revenue, and certain other claims may also not be reimbursed by insurance carriers. Any such lack of reimbursement may cause the Group to incur substantial costs. In addition, the Group could decide to retain more risk in the future, resulting in higher risk of losses, which could be material. Moreover, the Group may not be able to maintain adequate insurance in the future at rates that the Group considers reasonable or be able to obtain insurance against certain risks.

Recent developments in Swiss corporate governance may affect the Company’s ability to attract and retain top executives

On January 1, 2014, subject to certain transitional provisions, the Swiss Federal Council Ordinance Against Excessive Compensation at Public Companies (the “Ordinance”) became effective. The Ordinance, among other things, (a) requires a binding shareholder “say on pay” vote with respect to the compensation of members of the Company’s executive management and the Transocean Board, (b) generally prohibits the making of severance, advance, transaction premiums and similar payments to members of the Company’s executive management and the Transocean Board, and (c) requires a mandatory one-year term of the Transocean Board and the amendment of the Company’s Articles of Association to specify various compensation-related matters. At the 2014 annual general meeting, the Company’s shareholders approved amendments to the Company’s Articles of Association that implement the requirements of the Ordinance, and at each of the Company’s 2015, 2016 and 2017 annual general meetings the Company’s shareholders approved in a binding “say on pay” vote the compensation of members of the Company’s executive management and the Transocean Board. At the 2017 annual general meeting, the Company’s shareholders approved the maximum aggregate compensation of (1) the Transocean Board for the period between the 2017 annual general meeting and the 2018 annual general meeting and (2) the Company’s Executive Management Team for the year ending December 31, 2018. The Company’s shareholders will be asked to approve such matters for successive one-year periods at subsequent annual general meetings. The Ordinance further provides for criminal penalties against directors and members of executive management in case of noncompliance with certain of its requirements. The Ordinance may

negatively affect the Company’s ability to attract and retain executive management and members of the Transocean Board.

Corporate restructuring activity, divestitures, acquisitions and other business combinations and reorganizations could adversely affect the Group’s ability to achieve the Group’s strategic goals

The Group has undertaken and continues to seek appropriate opportunities for restructuring the Group’s organization, engaging in strategic acquisitions, divestitures and other business combinations in order to optimize the Group’s fleet and strengthen the Group’s competitiveness. The Group faces risks arising from these activities, which could adversely affect the Group’s ability to achieve its strategic goals. For example:

Certain transactions may result in other unanticipated adverse consequences.

Failure to recruit and retain key personnel could hurt the Group’s operations

The Group depends on the continuing efforts of key members of the Group’s management, as well as other highly skilled personnel, to operate and provide technical services and support for the Group’s business worldwide. Historically, competition for the personnel required for drilling operations has intensified as the number of rigs activated, added to worldwide fleets or under construction increased, leading to shortages of qualified personnel in the industry and creating upward pressure on wages and higher turnover. The Group may experience a reduction in the experience level of the Group’s personnel as a result of any increased turnover and ongoing staff reduction initiatives, which could lead to higher downtime and more operating incidents, which in turn could decrease revenues and increase costs. If increased competition for qualified personnel were to intensify in the future the Group may experience increases in costs or limits on operations.

Significant part or equipment shortages, supplier capacity constraints, supplier production disruptions, supplier quality and sourcing issues or price increases could increase the Group’s operating costs, decrease the Group’s revenues and adversely impact the Group’s operations

The Group’s reliance on third-party suppliers, manufacturers and service providers to secure equipment, parts, components and sub-systems used in the Group’s operations exposes the Group to volatility in the quality, prices and availability of such items. A disruption in the deliveries from third-party suppliers, manufacturers or

service providers, capacity constraints, production disruptions, price increases, quality control issues, recalls or other decreased availability of parts and equipment could adversely affect the Group’s ability to meet its commitments to customers, adversely impact the Group’s operations and revenues or increase the Group’s operating costs.

The Group’s labor costs and the operating restrictions under which the Group operates could increase as a result of collective bargaining negotiations and changes in labor laws and regulations

A substantial part of the Group’s total workforce are represented by, and some of the Group’s contracted labor work under, collective bargaining agreements, substantially all of which are subject to annual salary negotiation.  These negotiations could result in higher personnel expenses, other increased costs or increased operational restrictions as the outcome of such negotiations apply to all offshore employees not just the union members. Legislation has been introduced in the U.S. Congress that could encourage additional unionization efforts in the U.S., as well as increase the chances that such efforts succeed. Additional unionization efforts, if successful, new collective bargaining agreements or work stoppages could materially increase the Group’s labor costs and operating restrictions.

Failure to comply with anti-bribery statutes, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010, could result in fines, criminal penalties, drilling contract terminations and an adverse effect on the Group’s business

The U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act 2010 (“Bribery Act”) and similar anti-bribery laws in other jurisdictions, generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. The Group operates in many parts of the world that have experienced corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. If the Group is found to be liable for violations under the FCPA, the Bribery Act or other similar laws, either due to the Group’s acts or omissions or due to the acts or omissions of others, including the Group’s partners in various joint ventures, the Group could suffer from civil and criminal penalties or other sanctions, which could have a material adverse effect on the Group’s business, financial condition and results of operations. In addition, investors could negatively view potential violations, inquiries or allegations of misconduct under the FCPA, the Bribery Act or similar laws, which could adversely affect the Group’s reputation and the market for the Group’s shares.

The Group could also face fines, sanctions and other penalties from authorities in the relevant jurisdictions, including prohibition of the Group’s participation in or curtailment of business operations in those jurisdictions and the seizure of rigs or other assets. Additionally, the Group could also face other third-party claims by agents, shareholders, debt holders, or other interest holders or constituents of the Group. Further, disclosure of the subject matter of any investigation could adversely affect the Group’s reputation and the Group’s ability to obtain new business from potential customers or retain existing business from the Group’s current customers, to attract and retain employees and to access the capital markets. The Group’s customers in relevant jurisdictions could seek to impose penalties or take other actions adverse to the Group’s interests, and the Group may be required to dedicate significant time and resources to investigate and resolve allegations of misconduct, regardless of the merit of such allegations.

Regulation of greenhouse gases and climate change could have a negative impact on the Group’s business

A number of scientific studies suggests that emissions of certain gases, including greenhouse gases, carbon dioxide and methane, may be contributing to warming of the earth’s atmosphere and other climatic changes. In response to such studies, the issue of climate change and the effect of greenhouse gas emissions, in particular emissions from fossil fuels, are attracting increasing attention worldwide.

In the U.S., the U.S. Environmental Protection Agency has begun adopting and implementing a comprehensive suite of regulations to restrict emissions of greenhouse gases under existing provisions of the Clean Air Act. In addition, a number of other federal, state and regional efforts have focused on tracking or reducing greenhouse gas emissions. Efforts have also been made and continue to be made in the international community toward the adoption of international treaties or protocols that would address global climate change issues. In December 2015, the U.S. joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France, however at the date of this Prospectus the U.S.’ participation in such arrangement is in doubt. Nevertheless, the resulting Paris Agreement calls for the parties to undertake “ambitious efforts” to limit the average global temperature and to conserve and enhance sinks and reservoirs of greenhouse gases. The Paris Agreement, if ratified, establishes a framework for the parties to cooperate and report actions to reduce greenhouse gas emissions.

Because the Group’s business depends on the level of activity in the offshore oil and gas industry, existing or future laws, regulations, treaties or international agreements related to greenhouse gases and climate change, including incentives to conserve energy or use alternative energy sources, could have a negative impact on the Group’s business if such laws, regulations, treaties or international agreements reduce the worldwide demand for oil and gas or limit drilling opportunities. In addition, such laws, regulations, treaties or international agreements could result in increased compliance costs or additional operating restrictions, which may have a negative impact on the Group’s business.

The Group is subject to litigation that, if not resolved in the Group’s favor and not sufficiently insured against, could have a material adverse effect on the Group

The Group is subject to a variety of disputes, investigations and litigation. Certain of the companies in the Group are named as defendants in numerous lawsuits alleging personal injury as a result of exposure to asbestos or toxic fumes or resulting from other occupational diseases, such as silicosis, and various other medical issues that can remain undiscovered for a considerable amount of time. Some of these companies in the Group that have been put on notice of potential liabilities have no assets. Further, the Group’s patent for dual-activity technology has been successfully challenged in certain jurisdictions, and the Group has been accused of infringing other patents. Other companies in the Group are subject to litigation relating to environmental damage. The Group cannot predict the outcome of the cases involving those companies or the potential costs to resolve them. Insurance may not be applicable or sufficient in all cases, insurers may not remain solvent, policies may not be located, and liabilities associated with the Macondo well incident may exhaust some or all of the insurance available to cover certain claims. Suits against non-asset-owning companies in the Group have and may in the future give rise to alter ego or successor-in-interest claims against the Group and the Group’s asset-owning subsidiaries to the extent a Group company is unable to pay a claim or insurance is not available or sufficient to cover the claims. The Group is subject to litigation with certain of the Group’s customers and suppliers as well as a number of significant tax disputes (including the DSME arbitration case and a tax matter relating to Songa Offshore). To the extent that one or more pending or future litigation matters is not resolved in

the Group’s favor and is not covered by insurance, a material adverse effect on the Group’s financial results and condition could result.

The Group’s information technology systems are subject to cybersecurity risks and threats

The Group depends on digital technologies to conduct the Group’s offshore and onshore operations, to collect payments from customers and to pay vendors and employees. Threats to the Group’s information technology systems associated with cybersecurity risks and cyber-incidents or attacks continue to grow. In addition, breaches to the Group’s systems could go unnoticed for some period of time. Risks associated with these threats include disruptions of certain systems on the Group’s rigs; other impairments of the Group’s ability to conduct the Group’s operations; loss of intellectual property, proprietary information or customer data; disruption of the Group’s customers’ operations; loss or damage to the Group’s customer data delivery systems; and increased costs to prevent, respond to or mitigate cybersecurity events. If such a cyber-incident were to occur, it could have a material adverse effect on the Group’s business, financial condition, cash flows and results of operations.

Public health threats could have a material adverse effect on the Group’s operations and its financial results

Public health threats, such as Severe Acute Respiratory Syndrome, severe influenza and other highly communicable viruses or diseases, outbreaks of which have already occurred in various parts of the world in which the Group operates, could adversely impact the Group’s operations, the operations of the Group’s customers and the global economy, including the worldwide demand for oil and natural gas and the level of demand for the Group’s services. Quarantine of personnel or inability to access the Group’s offices or rigs could adversely affect the Group’s operations. Travel restrictions or operational problems in any part of the world in which the Group operates, or any reduction in the demand for drilling services caused by public health threats in the future, may materially impact operations and adversely affect the Group’s financial results.

A change in tax laws, treaties or regulations, or their interpretation, of any country in which the Group has operations, are incorporated or are resident could result in a higher tax rate on the Group’s worldwide earnings, which could result in a significant negative impact on the Group’s earnings and cash flows from operations

The Group operates worldwide. Consequently, the Group is subject to changes in applicable tax laws, treaties or regulations in the jurisdictions in which the Group operates, which could include laws or policies directed toward companies organized in jurisdictions with low tax rates. A material change in the tax laws, treaties or regulations, or their interpretation or application, of any country in which the Group has significant operations, or in which the Group is incorporated or resident, could result in a higher effective tax rate on the Group’s worldwide earnings and such change could be significant to the Group’s financial results.

Legislative tax proposals intending to eliminate some perceived tax advantages of companies that have legal domiciles outside the U.S., but have certain U.S. connections, have repeatedly been introduced in the U.S. Congress. Recent examples include, but are not limited to, legislative proposals that would broaden the circumstances in which a non-U.S. company would be considered a U.S. resident, including the use of “management and control” provisions to determine corporate residency, and proposals that could override certain tax treaties and limit treaty benefits on certain payments by U.S. subsidiaries to non-U.S. affiliates. Whether any such U.S. tax legislation will be enacted and its impact on the Group is uncertain. Any material change in tax laws or policies, or their interpretation, resulting from such legislative proposals could result in a

higher effective tax rate on the Group’s worldwide earnings and such change could have a material adverse effect on the Group’s consolidated statement of financial position, results of operations or cash flows.

In a referendum held on February 12, 2017, Swiss voters rejected a corporate tax legislative proposal that would have abolished certain cantonal tax privileges as well as implement other significant changes to existing tax laws and practices starting in 2019. These legislative proposals were in response to certain guidance from and demands by the European Union and the Organization for Economic Co-operation and Development (the “OECD”). Switzerland must now give consideration to a revised corporate tax reform proposal. Switzerland’s implementation of any material change in tax laws or policies or its adoption of new interpretations of existing tax laws and rulings could result in a higher effective tax rate on the Group’s worldwide earnings and such change could have a material adverse effect on the Group’s consolidated statement of financial position, results of operations or cash flows.

Similarly, in October 2015, the OECD issued its action plan of tax reform measures that called for member states to take action to prevent “base erosion and profit shifting.” Some of these measures impact transfer pricing, requirements to qualify for tax treaty benefits, and the definition of permanent establishments depending on each jurisdiction’s adoption and interpretation of such proposals. The European Union issued its Anti-Tax Avoidance Directive in 2016 that required its member states to adopt specific tax reform measures by 2019. Any material change in tax laws or policies, or their interpretation, resulting from such legislative proposals or inquiries could result in a higher effective tax rate on the Group’s worldwide earnings and such change could have a material adverse effect on the Group’s consolidated statement of financial position, results of operations or cash flows.

Other tax jurisdictions in which the Group operates may consider implementing similar legislation. The implementation of such legislation, any other material changes in tax laws or policies or the adoption of new interpretations of existing tax laws and rulings could result in a higher effective tax rate on the Group’s worldwide earnings and any such change could have a material adverse effect on the Group’s consolidated statement of financial position, results of operations or cash flows.

Recently enacted U.S. Tax Reform Legislation could have material effects on the Group’s earnings and cash flows from operations

On December 22, 2017, the President of the United States signed into law the U.S. Tax Legislation, which makes significant changes to various areas of U.S. federal income tax law and which could significantly affect the Group’s business, operations, financial condition and results of operations, and may have an adverse impact on investors in shares in the Company.  These changes may include (i) the taxation of unrepatriated earnings of non-U.S. subsidiaries of the Company’s U.S. affiliates as part of the transition of U.S. international taxation from a worldwide tax system to a territorial tax system, (ii) a deferral or permanent reduction in the amount of interest that is deductible for U.S. federal income tax purposes after 2017, and (iii) additional U.S. tax after 2017 on certain deductible payments by the Company’s U.S. subsidiaries to its non-U.S. subsidiaries if such payments are subject to reduced rates of U.S. withholding tax under a treaty.  Although the Company is evaluating the U.S. Tax Legislation with its professional advisers, the impact on the U.S. Group’s business is currently uncertain.

A loss of a major tax dispute or a successful tax challenge to the Group’s operating structure, intercompany pricing policies or the taxable presence of the Group’s key subsidiaries in certain countries could result in a higher tax rate on the Group’s worldwide earnings, which could result in a significant negative impact on the Group’s earnings and cash flows from operations

The Company is a Swiss corporation that operates through the Company’s various subsidiaries in a number of countries throughout the world. Consequently, the Company is subject to tax laws, treaties and regulations in and between the countries in which the Group operates. The Group’s income taxes are based upon the applicable tax laws and tax rates in effect in the countries in which the Group operates and earns income, as well as upon the Group’s operating structures in these countries.

The Group’s income tax returns are subject to review and examination. The Group’s does not recognize the benefit of income tax positions the Group believes are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges the Group’s operational structure, intercompany pricing policies or the taxable presence of the Group’s key subsidiaries in certain countries; or if the terms of certain income tax treaties are interpreted in a manner that is adverse to the Group’s structure; or if the Group loses a material tax dispute in any country, the Group’s effective tax rate on the Group’s worldwide earnings could increase substantially and the Group’s earnings and cash flows from operations could be materially adversely affected. For example, the Group cannot be certain that the U.S. Internal Revenue Service (“IRS”) will not successfully contend that the Group or any of the Group’s key subsidiaries were or are engaged in a trade or business in the U.S. or, when applicable, that the Group or any of the Group’s key subsidiaries maintained or maintain a permanent establishment in the U.S., since, among other things, such determination involves considerable uncertainty. If the Group or any of its key subsidiaries were considered to have been engaged in a trade or business in the U.S., when applicable, through a permanent establishment, the Group could be subject to U.S. corporate income and additional branch profits taxes on the portion of the Group’s earnings effectively connected to such U.S. business during the period in which this was considered to have occurred, in which case the Group’s effective tax rate on worldwide earnings for that period could increase substantially, and the Group’s earnings and cash flows from operations for that period could be adversely affected.

As a Swiss corporation, the Company is subject to Swiss legal provisions that may limit its flexibility to swiftly implement certain initiatives or strategies

The Company is required, from time to time, to evaluate the carrying amount of the Company’s investments in affiliates, as presented on the Company’s Swiss standalone balance sheet of the Company’s statutory accounts. If the Company were to determine that the carrying amount of any such investment exceeded its fair value, the Company may conclude that such investment is impaired. The recognized loss associated with such a non-cash impairment could result in the Company’s net assets no longer covering the Company’s statutory share capital and statutory capital reserves. Under Swiss law, if the Company’s net assets cover less than 50% of the Company’s statutory share capital and statutory capital reserves, the Transocean Board must in these circumstances convene a general meeting of shareholders and propose measures to remedy such a capital loss. The appropriate measures depend on the relevant circumstances and the magnitude of the recognized loss and may include seeking shareholder approval for offsetting the aggregate loss, or a portion thereof, with the Company’s statutory capital reserves including qualifying additional paid-in capital otherwise available for distributions to shareholders or raising new equity. Depending on the circumstances, the Company may also need to use qualifying additional paid-in capital available for distributions in order to reduce the Company’s

accumulated net loss and such use might reduce the Company’s ability to make distributions without subjecting the Company’s shareholders to Swiss withholding tax. These Swiss law requirements could limit the Company’s flexibility to swiftly implement certain initiatives or strategies.

The Company is subject to anti-takeover provisions

The Company’s Articles of Association and Swiss law contain provisions that could prevent or delay an acquisition of the Company by means of a tender offer, a proxy contest or otherwise. These provisions may also adversely affect prevailing market prices for the Company’s shares. These provisions, among other things:

Risks Related to the Industry in Which the Group Operates

The global nature of the Group’s operations involves additional risks

The Group operates in various regions throughout the world, which may expose the Group to political and other uncertainties, including risks of:

The Group’s non-U.S. contract drilling operations are subject to various laws and regulations in certain countries in which the Group operates, including laws and regulations relating to the import and export, equipment and operation of drilling units, currency conversions and repatriation, oil and gas exploration and development, taxation and social contributions of offshore earnings and earnings of expatriate personnel. The

Group is also subject to the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) and other U.S. laws and regulations governing the Group’s international operations. In addition, various state and municipal governments, universities and other investors have proposed or adopted divestment and other initiatives regarding investments including, with respect to state governments, by state retirement systems in companies that do business with countries that have been designated as state sponsors of terrorism by the U.S. State Department. Failure to comply with applicable laws and regulations, including those relating to sanctions and export restrictions, may subject the Group to criminal sanctions or civil remedies, including fines, denial of export privileges, injunctions or seizures of assets. Investors could view any potential violations of OFAC regulations negatively, which could adversely affect the Group’s reputation and the market for the Company’s shares.

Governments in some countries have become increasingly active in regulating and controlling the ownership of concessions and companies holding concessions, the exploration for oil and gas and other aspects of the oil and gas industries in their countries, including local content requirements for participating in tenders for certain drilling contracts. Many governments favor or effectively require the awarding of drilling contracts to local contractors or require non-local contractors to employ citizens of, or purchase supplies from, a particular jurisdiction or require use of a local agent. In addition, government action, including initiatives by the Organisation of the Petroleum Exporting Countries (“OPEC”), may continue to cause oil or gas price volatility. In some areas of the world, this governmental activity has adversely affected the amount of exploration and development work by major oil companies and may continue to do so.

A substantial portion of the Group’s drilling contracts are partially payable in local currency. Those amounts may exceed the Group’s local currency needs, leading to the accumulation of excess local currency, which, in certain instances, may be subject to either temporary blocking or other difficulties converting to U.S. dollars, the Group’s functional currency, or to other currencies in which the Group operates. Excess amounts of local currency may be exposed to the risk of currency exchange losses.

The shipment of goods, services and technology across international borders subjects the Group to extensive trade laws and regulations. The Group’s import and export activities are governed by unique customs laws and regulations in each of the countries where the Group operates. Moreover, many countries, including the U.S., control the import and export of certain goods, services and technology and impose related import and export recordkeeping and reporting obligations. Governments also may impose economic sanctions against certain countries, persons and other entities that may restrict or prohibit transactions involving such countries, persons and entities, and the Group is also subject to the U.S. anti-boycott law.

The laws and regulations concerning import and export activity, recordkeeping and reporting, import and export control and economic sanctions are complex and constantly changing. These laws and regulations may be enacted, amended, enforced or interpreted in a manner materially impacting the Group’s operations. Ongoing economic challenges may increase some governments’ efforts to enact, enforce, amend or interpret laws and regulations as a method to increase revenue. Shipments can be delayed and denied import or export for a variety of reasons, some of which are outside the Group’s control and some of which may result from failure to comply with existing legal and regulatory regimes. Shipping delays or denials could cause unscheduled operational downtime.

An inability to obtain visas and work permits for the Group’s employees on a timely basis could impact the Group’s operations and have an adverse effect on the Group’s business. The Group’s ability to operate

worldwide depends on the Group’s ability to obtain the necessary visas and work permits for the Group’s personnel to travel in and out of, and to work in, the jurisdictions in which the Group operates. Governmental actions in some of the jurisdictions in which the Group operates may make it difficult for the Group to move its personnel in and out of these jurisdictions by delaying or withholding the approval of these permits. If the Group is not able to obtain visas and work permits for the employees needed to operate its rigs on a timely basis, the Group might not be able to perform its obligations under the Group’s drilling contracts, which could allow the Group’s customers to cancel the contracts. If the Group’s customers cancel some of the Group’s drilling contracts, and the Group is unable to secure new drilling contracts on a timely basis and on substantially similar terms, it could adversely affect the Group’s consolidated statement of financial position, results of operations or cash flows.

Compliance with or breach of environmental laws can be costly and/or expose the Group to liability and could limit the Group’s operations

The Group’s business in the offshore drilling industry is affected by laws and regulations relating to the energy industry and the environment, including international conventions and treaties, and regional, national, state, and local laws and regulations. The offshore drilling industry depends on demand for services from the oil and gas exploration and production industry, and, accordingly, the Group is directly affected by the adoption of laws and regulations that, for economic, environmental or other policy reasons, curtail exploration and development drilling for oil and gas. Compliance with such laws, regulations and standards, where applicable, may require the Group to make significant capital expenditures, such as the installation of costly equipment or operational changes, and may affect the resale values or useful lives of the Group’s rigs.

The Group may also incur additional costs in order to comply with other existing and future regulatory obligations, including, but not limited to, costs relating to air emissions, including greenhouse gases, the management of ballast waters, maintenance and inspection, development and implementation of emergency procedures and insurance coverage or other financial assurance of the Group’s ability to address pollution incidents. Offshore drilling in certain areas has been curtailed and, in certain cases, prohibited because of concerns over protection of the environment. These costs could have a material adverse effect on the Group’s consolidated statement of financial position, results of operations or cash flows. A failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of the Group’s operations.

To the extent new laws are enacted or other governmental actions are taken that prohibit or restrict offshore drilling or impose additional environmental protection requirements that result in increased costs to the oil and gas industry, in general, or the offshore drilling industry, in particular, the Group’s business or prospects could be materially adversely affected. The operation of the Group’s drilling rigs will require certain governmental approvals. These governmental approvals may involve public hearings and costly undertakings on the Group’s part. The Group may not obtain such approvals or such approvals may not be obtained in a timely manner. If the Group fails to timely secure the necessary approvals or permits, the Group’s customers may have the right to terminate or seek to renegotiate their drilling contracts to the Group’s detriment. The amendment or modification of existing laws and regulations or the adoption of new laws and regulations curtailing or further regulating exploratory or development drilling and production of oil and gas could have a material adverse effect on the Group’s business, operating results or financial condition. Compliance with any such new legislation or regulations could have an adverse effect on the Group’s statements of operations and cash flows.

As an operator of mobile offshore drilling units in some offshore areas, the Group may be liable for damages and costs incurred in connection with oil spills or waste disposals related to those operations, and the Group may also be subject to significant fines in connection with spills. For example, an oil spill could result in significant liability, including fines, penalties and criminal liability and remediation costs for natural resource damages, as well as third-party damages, to the extent that the contractual indemnification provisions in the Group’s drilling contracts are not enforceable or otherwise sufficient, or if the Group’s customers are unwilling or unable to contractually indemnify the Group from these risks. Additionally, the Group may not be able to obtain such indemnities in the Group’s future drilling contracts, and the Group’s customers may not have the financial capability to fulfill their contractual obligations to the Company. Also, these indemnities may be held to be unenforceable in certain jurisdictions, as a result of public policy or for other reasons. For example, one of the courts in the litigation related to the Macondo well incident has refused to enforce aspects of the Transocean Group’s indemnity with respect to certain environmental-related liabilities. Laws and regulations protecting the environment have become more stringent in recent years, and may in some cases impose strict liability, rendering a person liable for environmental damage without regard to negligence. These laws and regulations may expose the Group to liability for the conduct of or conditions caused by others or for acts that were in compliance with all applicable laws at the time they were performed. The application of these requirements or the adoption of new requirements or measures could have a material adverse effect on the Group’s consolidated statement of financial position, results of operations or cash flows. In addition, the Consent Decree (as defined below) and probation arising out of certain Transocean Group subsidiaries’ cooperation guilty plea agreement by and among the U.S. Department of Justice (the “DOJ”) and certain of the Transocean Group’s affiliates (the “Plea Agreement”), add to these regulations, requirements and liabilities. One Transocean Group subsidiary’s guilty plea to negligently discharging oil into the U.S. Gulf of Mexico, in violation of the Clean Water Act,  in connection with the Macondo well incident caused the Company to incur liabilities under the environmental laws relating to the Macondo well incident. The Company may be subject to additional liabilities and penalties.

The continuing effects of the enhanced regulations enacted following the Macondo well incident and of agreements applicable to the Transocean Group could materially and adversely affect the Group’s worldwide operations

Following the Macondo well incident, enhanced governmental safety and environmental requirements applicable to both deepwater and shallow water operations were adopted for drilling in the U.S. Gulf of Mexico. In order to obtain drilling permits, operators must submit applications that demonstrate compliance with the enhanced regulations, which require independent third-party inspections, certification of well design and well control equipment and emergency response plans in the event of a blowout, among other requirements. Operators have previously had, and may in the future have, difficulties obtaining drilling permits in the U.S. Gulf of Mexico. In addition, the oil and gas industry has adopted new equipment and operating standards, such as the American Petroleum Institute Standard 53 related to the installation and testing of well control equipment. These new safety and environmental guidelines and standards and any further new guidelines or standards the U.S. government or industry may issue or any other steps the U.S. government or industry may take, could disrupt or delay operations, increase the cost of operations, increase out-of-service time or reduce the area of operations for drilling rigs in the U.S. and non-U.S. offshore areas.

Other governments could take similar actions related to implementing new safety and environmental regulations in the future. Additionally, some of the Group’s customers have elected to voluntarily comply with some or all of the new inspections, certification requirements and safety and environmental guidelines on rigs operating outside of the U.S. Gulf of Mexico. Additional governmental regulations and requirements

concerning licensing, taxation, equipment specifications and training requirements or the voluntary adoption of such requirements or guidelines by the Group’s customers could increase the costs of the Group’s operations, increase certification and permitting requirements, increase review periods and impose increased liability on offshore operations. The requirements applicable to the Transocean Group under the Transocean Group’s settlement with the DOJ cover safety, environmental, reporting, operational and other matters (the “Consent Decree”) and are in addition to the regulations applicable to other industry participants and may require additional agreements and corporate compliance resources that, together with the Plea Agreement could cause the Group to incur additional costs and liabilities. The continuing effects of the enhanced regulations may also decrease the demand for drilling services, negatively affect day rates and increase out-of-service time, which could ultimately have a material adverse effect on the Group’s revenues and profitability.

The offshore drilling industry is highly competitive and cyclical, with intense price competition

The offshore contract drilling industry is highly competitive with numerous industry participants, none of which has a dominant market share. Drilling contracts are traditionally awarded on a competitive bid basis. Although rig availability, service quality and technical capability are drivers of customer contract awards, bid pricing and intense price competition are often key determinants for which a qualified contractor is awarded a job.

The offshore drilling industry has historically been cyclical and is impacted by oil and natural gas price levels and volatility. There have been periods of high customer demand, limited rig supply and high day rates, followed by periods of low customer demand, excess rig supply and low day rates. Changes in commodity prices can have a dramatic effect on rig demand, and periods of excess rig supply may intensify competition in the industry and result in the idling of older and less technologically advanced equipment. The Group has idled and stacked rigs, and may in the future idle or stack additional rigs or enter into lower day rate drilling contracts in response to market conditions. The Group cannot predict when or if any idled or stacked rigs will return to service.

During prior periods of high day rates and rig utilization rates, the Group and other industry participants have responded to increased customer demand by increasing the supply of rigs through ordering the construction of new units. In periods of low oil and natural gas price levels, growth in new construction has historically resulted in an oversupply of rigs and has caused a subsequent decline in day rates and rig utilization rates, sometimes for extended periods of time. Presently, there are numerous recently constructed high-specification floaters and other drilling units capable of competing with the Group’s rigs that have entered the global market, and there are more that are under construction.

The entry into service of these new units has increased and will continue to increase supply. The increased supply has contributed to and may continue to contribute to a reduction in day rates as rigs are absorbed into the active fleet and has led to accelerated stacking of the existing fleet.

Two of the Group’s three ultra-deepwater drillships currently under construction have not been contracted for work. Combined with the rapid increase in the number of rigs in the global market completing contracts and becoming idle, the number of new units expected to be delivered without contracts has intensified and may further intensify price competition. Any further increase in construction of new units would likely exacerbate the negative impact of increased supply on day rates and utilization rates. Additionally, lower market day rates and intense price competition may drive customers to demand renegotiation of existing contracts to lower day

rates in exchange for longer contract terms. In an oversupplied market, the Group may have limited bargaining power to negotiate on more favorable terms. Lower day rates and rig utilization rates could adversely affect the Group’s revenues and profitability.

The Group may not be able to renew or obtain new drilling contracts for rigs whose contracts are expiring or are terminated or obtain drilling contracts for the Group’s uncontracted newbuilds, which could adversely affect the Group’s consolidated statements of operations

The Group’s ability to renew expiring drilling contracts or obtain new drilling contracts will depend on the prevailing market conditions at the time. If the Group is unable to obtain new drilling contracts in direct continuation with existing contracts or for the Group’s uncontracted newbuild units, or if new drilling contracts are entered into day rates substantially below the existing day rates or on terms otherwise less favorable compared to existing contract terms, the Group’s revenues and profitability could be adversely affected.

The offshore drilling markets in which the Group compete experience fluctuations in the demand for drilling services. A number of existing drilling contracts for the Group’s drilling rigs that are currently operating are scheduled to expire before December 31, 2018. As of January 31, 2018, two of the ultra-deepwater drillships the Group currently has under construction as part of the Group’s newbuild program are being constructed without customer drilling contracts. The Group will attempt to secure drilling contracts for these units prior to their completion. The Group may be unable to obtain drilling contracts for the Group’s rigs that are currently operating upon the expiration or termination of such contracts or obtain drilling contracts for the Group’s newbuilds, and there may be a gap in the operation of the rigs between the current contracts and subsequent contracts. In particular, if oil and natural gas prices remain low, as is currently the case, or it is expected that such prices will decrease in the future, at a time when the Group is seeking drilling contracts for the Group’s rigs, the Group may be unable to obtain drilling contracts at attractive day rates or at all.

The Group’s business depends on the level of activity in the offshore oil and gas industry, which is significantly affected by volatile oil and gas prices and other factors

The Group’s business depends on the level of activity in oil and gas exploration, development and production in offshore areas worldwide. Demand for the Group’s services depends on oil and natural gas industry activity and expenditure levels that are directly affected by trends in oil and, to a lesser extent, natural gas prices. Oil and gas prices are extremely volatile and are affected by numerous factors, including the following:
