The forward-looking statements speak only as of the date hereof, and we undertake no obligation to publicly update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise.

Our forward-looking statements express our current expectations or forecasts of possible future results or events, including our future financial and operational performance and cash balances; revenue efficiency levels; market outlook; forecasts of trends; future client contract opportunities; contract dayrates; our business strategies and plans and objectives of management; estimated duration of client contracts; backlog; expected capital expenditures; projected costs and savings; the potential impact of our Chapter 11 proceedings on our future operations and ability to finance our business; our ability to complete the restructuring transactions contemplated by our plan of reorganization; projected costs and expenses in connection with our plan of reorganization; and our ability to emerge from our Chapter 11 proceedings and continue as a going concern.

Although we believe that the assumptions and expectations reflected in our forward-looking statements are reasonable and made in good faith, these statements are not guarantees, and actual future results may differ materially due to a variety of factors. These statements are subject to a number of risks and uncertainties and are based on a number of judgments and assumptions as of the date such statements are made about future events, many of which are beyond our control. Actual events and results may differ materially from those anticipated, estimated, projected or implied by us in such statements due to a variety of factors, including if one or more of these risks or uncertainties materialize, or if our underlying assumptions prove incorrect.

Important factors that could cause actual results to differ materially from our expectations include: the global oil and gas market and its impact on demand for our services; the offshore drilling market, including reduced capital expenditures by our clients; changes in worldwide oil and gas supply and demand; rig availability and supply and demand for high specification drillships and other drilling rigs competing with our fleet; costs related to stacking of rigs; our ability to enter into and negotiate favorable terms for new drilling contracts or extensions; our ability to successfully negotiate and consummate definitive contracts and satisfy other customary conditions with respect to letters of intent and letters of award that we receive for our drillships; our substantial level of indebtedness; possible cancellation, renegotiation, termination or suspension of drilling contracts as a result of mechanical difficulties, performance, market changes or other reasons; our ability to execute our business plan and continue as a going concern in the long term; our ability to obtain Bankruptcy Court approval with respect to motions or other requests made to the Bankruptcy Court in our Chapter 11 proceedings, including maintaining strategic control as debtor in-possession; our ability to confirm and consummate our plan of reorganization in accordance with the terms of the Plan and the settlement; risks attendant to the bankruptcy process including the effects of our Chapter 11 proceedings on our operations and agreements, including our relationships with employees, regulatory authorities, clients, suppliers, banks and other financing sources, insurance companies and other third parties; the effects of our Chapter 11 proceedings on our Company and on the interests of various constituents, including holders of our common shares and debt instruments; the potential adverse effects of our Chapter 11 proceedings on our liquidity, results of operations, or business prospects; the outcome of Bankruptcy Court rulings in our Chapter 11 proceedings as well as all other pending litigation and arbitration matters; the length of time that we will operate under Chapter 11 protection and the continued availability of operating capital during the pendency of the proceedings; our ability to access adequate debtor-in-possession financing or use cash collateral; risks associated with third-party motions in our Chapter 11 proceedings, which may interfere with our ability to timely confirm and consummate our plan of reorganization and restructuring generally; increased advisory costs including administrative and legal costs to complete our plan of reorganization and other litigation; the risk that our plan of reorganization may not be accepted or confirmed, in which case there can be no assurance that our Chapter 11 proceedings will continue rather than be converted to Chapter 7 liquidation cases or that any alternative plan of reorganization would be on terms as favorable to holders of claims and interests as the terms of our Plan; the cost, availability and access to capital and financial markets, including the ability to secure new financing after emerging from our Chapter 11 proceedings; and the other risk factors described in our 2017 Annual Report on Form 20-F and our Current Reports on Form 6-K.
