⁽¹⁾ For rigs that may be modified to drill in deeper water depths, both the currently outfitted and maximum upgrade capabilities are shown.

⁽²⁾ Contract duration does not include any unexercised optional extensions. Contract end dates can vary based on how long it takes to complete the wells subject to the contract.

⁽³⁾ Prior to stacking, upfront steps are taken to preserve the rig. This may include a quayside power source to dehumidify key equipment and/or provide electrical current to the hull to prevent corrosion. Also, certain equipment may be removed from the rig for storage in a temperature-controlled environment. While stacked, large equipment that remains on the rig is periodically inspected and maintained by Ensco personnel. These steps are designed to reduce the time and lower cost to reactivate the rig when market conditions improve.



			Ensco plc Fleet Status Report 20 February 2018

Additional Information Regarding this Fleet Status Report

Day Rate and Terms. The day rates reflected in this Fleet Status Report are stated in U.S. dollars and are the operating day rates charged to customers, which may include estimated contractual adjustments for changes in operating costs and/or reimbursable cost adjustments for ongoing expenses such as crew, catering, insurance and taxes. The day rates, however, do not include certain types of non-recurring revenues such as lump sum mobilization payments, revenues earned during mobilizations, revenues associated with contract preparation and other non-recurring reimbursable items such as mobilizations and capital enhancements, and the impact of the fair market value adjustments to previously acquired drilling contracts. Routine and non-routine downtime may reduce the actual revenues recognized during the contract term. Additionally, we sometimes negotiate special rates and/or day rate adjustments with customers that may reduce revenues recognized. Ensco announced in its Fleet Status Report dated 22 February 2017 that going forward it does not expect to release day rates for new contracts in its Fleet Status Reports. Significant zero rate estimates are reflected in the comments section for 2017 and 2018.

Forward Looking Statement. Statements contained in this Fleet Status Report that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements include words or phrases such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “project,” “could,” “may,” “might,” “should,” “will” and similar words and specifically include statements involving future rig day rates including adjustments with the customer; discussions with the customer; backlog; cost adjustments; utilization; estimated rig availability; expected work commitments and contracts; contract duration, status, terms and other contract commitments; letters of intent, letters of award or other correspondence indicating an award; rig enhancement projects; new rig commitments; the expected period of time and number of rigs that will be in a shipyard for repairs, maintenance, enhancement or construction; sale leaseback transactions; scheduled delivery dates for new rigs; and the timing of delivery, mobilization, contract commencement, relocation or other movement of rigs. Such statements are subject to numerous risks, uncertainties and assumptions that may cause actual results to vary materially from those indicated, including commodity price fluctuations, customer demand, new rig supply, downtime and other risks associated with offshore rig operations; relocations; costs and difficulties related to the integration of Atwood Oceanics, Inc.; severe weather or hurricanes; changes in worldwide rig supply and demand, competition and technology; future levels of offshore drilling activity; governmental action, civil unrest and political and economic uncertainties; terrorism, piracy and military action; risks inherent to shipyard rig construction, repair, maintenance or enhancement; possible cancellation, suspension; repudiation; or termination of drilling contracts, including termination for convenience (without cause), as a result of mechanical difficulties, performance, customer liquidity and finances, the decline or the perceived risk of a further decline in oil and/or natural gas prices, or other reasons; the cancellation of letters of intent or any failure to execute definitive contracts following announcements of letters of intent or letters of award or other expected work commitments or awards; the outcome of litigation, legal proceedings, investigations or other claims or contract disputes; governmental regulatory, legislative and permitting requirements affecting drilling operations; our ability to attract and retain skilled personnel on commercially reasonable terms; environmental or other liabilities, risks or losses; debt restrictions that may limit our liquidity and flexibility; and cybersecurity risks and threats. In addition to the numerous factors described above, you should also carefully read and consider “Item 1A. Risk Factors” in Part I and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II of our most recent annual report on Form 10-K, as updated in our subsequent quarterly reports on Form 10-Q, which are available on the SEC’s website at www.sec.gov or on the Investor Relations section of our website at www.enscoplc.com. Each forward-looking statement contained herein speaks only as of the date of this Fleet Status Report, and we undertake no obligation to publicly update or revise any forward looking statements, except as required by law.
