FORWARD-LOOKING STATEMENTS
  
Statements contained in this report that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.  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 regarding expected financial performance; expected utilization, day rates, revenues, operating expenses, contract term, contract backlog, capital expenditures, insurance, financing and funding; the timing of availability, delivery, mobilization, contract commencement or relocation or other movement of rigs; future rig construction (including construction in progress and completion thereof), enhancement, upgrade or repair and timing and cost thereof; the suitability of rigs for future contracts; general market, business and industry conditions, trends and outlook; future operations; the impact of increasing regulatory complexity; expected contributions from our rig fleet expansion program and our program to high-grade the rig fleet by investing in new equipment and divesting selected assets and underutilized rigs; expense management; and the likely outcome of litigation, legal proceedings, investigations or insurance or other claims and the timing thereof.

Such statements are subject to numerous risks, uncertainties and assumptions that may cause actual results to vary materially from those indicated, including:

•	downtime and other risks associated with offshore rig operations or rig relocations, including rig or equipment failure, damage and other unplanned repairs, the limited availability of transport vessels, hazards, self-imposed drilling limitations and other delays due to severe storms and hurricanes and the limited availability or high cost of insurance coverage for certain offshore perils;	

•	changes in worldwide rig supply and demand, competition or technology, including changes as a result of delivery of newbuild drilling rigs;	

•	changes in future levels of drilling activity and expenditures, whether as a result of global capital markets and liquidity, prices of oil and natural gas or otherwise, which may cause us to idle or stack additional rigs;	

•	governmental action, terrorism, piracy, military action and political and economic uncertainties, including uncertainty or instability resulting from civil unrest, political demonstrations, mass strikes, epidemic or pandemic disease, or an escalation or additional outbreak of armed hostilities or other crises in oil or natural gas producing areas of the Middle East, North Africa, West Africa or other geographic areas, which may result in expropriation, nationalization, confiscation or deprivation of our assets or result in claims of a force majeure situation;	

•	risks inherent to shipyard rig construction, repair or enhancement, including risks associated with concentration of our construction contracts with three shipyards, unexpected delays in equipment delivery and engineering or design issues following delivery, or changes in commencement, completion or service dates;	

•	possible cancellation or suspension of drilling contracts as a result of mechanical difficulties, performance or other reasons;	

•	the outcome of litigation, legal proceedings, investigations or other claims or contract disputes, including any inability to collect receivables or resolve significant contractual or day rate disputes, any purported renegotiation, nullification, cancellation or breach of contracts with customers or other parties and any failure to negotiate or complete definitive contracts following announcements of receipt of letters of intent;	

•	governmental regulatory, legislative and permitting requirements affecting drilling operations, including limitations on drilling locations (such as the Gulf of Mexico during hurricane season);	

1

		
•	new and future regulatory, legislative or permitting requirements, future lease sales, changes in laws, rules and regulations that have or may impose increased financial responsibility, additional oil spill abatement contingency plan capability requirements and other governmental actions that may result in claims of force majeure or otherwise adversely affect our existing drilling contracts;	

•	our ability to attract and retain skilled personnel on commercially reasonable terms, whether due to labor regulations, unionization or otherwise;	

•	environmental or other liabilities, risks or losses, whether related to storm or hurricane damage, losses or liabilities (including wreckage or debris removal), collisions, groundings, blowouts, fires, explosions and other accidents or terrorism or otherwise, for which insurance coverage and contractual indemnities may be insufficient, unenforceable or otherwise unavailable;	

•	our ability to obtain financing and pursue other business opportunities may be limited by our debt levels and debt agreement restrictions;	

•	our ability to realize expected benefits from the 2009 redomestication as a U.K. public limited company and the related reorganization of Ensco’s corporate structure, including the effect of any changes in laws, rules and regulations, or the interpretation thereof, or in the applicable facts, that could adversely affect our status as a non-U.S. corporation for U.S. tax purposes or otherwise adversely affect our anticipated consolidated effective income tax rate;	

•	delays in actual contract commencement dates;	

•	adverse changes in foreign currency exchange rates, including their effect on the fair value measurement of our derivative instruments; and	

•	potential long-lived asset or goodwill impairments.	

In addition to the numerous risks, uncertainties and assumptions 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 the 2013 Form 10-K, as updated, the First Quarter Form 10-Q, as updated, and the Second Quarter Form 10-Q, all of which are available on the SEC's website at www.sec.gov and on the Investor Relations section of our website at www.enscoplc.com .

PART I - FINANCIAL INFORMATION

Item 1. Financial Statements

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
The Board of Directors and Shareholders
Ensco plc:

We have reviewed the condensed consolidated balance sheet of Ensco plc and subsidiaries (the Company) as of September 30, 2014, the related condensed consolidated statements of operations, and comprehensive income, for the three-month and nine-month periods ended September 30, 2014 and 2013, and the related condensed consolidated statements of cash flows for the nine-month periods ended September 30, 2014 and 2013. These condensed consolidated financial statements are the responsibility of the Company’s management.
We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Ensco plc and subsidiaries as of December 31, 2013, and the related consolidated statements of income, comprehensive income, and cash flows for the year then ended (not presented herein); and in our report dated February 26, 2014, except for notes 1, 2, 10, 11, 13, 14, 15, 16, and 17, as to which the date is September 22, 2014, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2013, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

Note 1 - Unaudited Condensed Consolidated Financial Statements
 
We prepared the accompanying condensed consolidated financial statements of Ensco plc and subsidiaries (the "Company," "Ensco," "our," "we" or "us") in accordance with accounting principles generally accepted in the United States of America ("GAAP"), pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") included in the instructions to Form 10-Q and Article 10 of Regulation S-X. The financial information included in this report is unaudited but, in our opinion, includes all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The December 31, 2013 condensed consolidated balance sheet data were derived from our 2013 audited consolidated financial statements, but do not include all disclosures required by GAAP. Certain previously reported amounts have been reclassified to conform to the current year presentation. The preparation of our condensed consolidated financial statements requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates.
 
The financial data for the three-month and nine-month periods ended September 30, 2014 and 2013 included herein have been subjected to a limited review by KPMG LLP, our independent registered public accounting firm. The accompanying independent registered public accounting firm's review report is not a report within the meaning of Sections 7 and 11 of the Securities Act of 1933, and the independent registered public accounting firm's liability under Section 11 does not extend to it.
 
Results of operations for the three-month and nine-month periods ended September 30, 2014 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2014 . We recommend these condensed consolidated financial statements be read in conjunction with our annual report on Form 10-K for the year ended December 31, 2013 filed with the SEC on February 26, 2014 , as updated by the Current Report on Form 8-K dated September 22, 2014 , and our quarterly reports on Form 10-Q filed with the SEC on April 29, 2014 , as updated by the Current Report on Form 8-K dated September 22, 2014 , and on August 1, 2014 .

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) ("Update 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective on January 1, 2017. Early application is not permitted. We are currently evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures.

Supplemental Executive Retirement Plan Assets
 
Our supplemental executive retirement plans (the "SERP") are non-qualified plans that provide eligible employees an opportunity to defer a portion of their compensation for use after retirement. Assets held in the SERP were marketable securities measured at fair value on a recurring basis using Level 1 inputs and were included in other assets, net, on our condensed consolidated balance sheets. The fair value measurement of assets held in the SERP was based on quoted market prices.
 
Derivatives
 
Our derivatives were measured at fair value on a recurring basis using Level 2 inputs. See "Note 3 - Derivative Instruments" for additional information on our derivatives, including a description of our foreign currency hedging activities and related methodologies used to manage foreign currency exchange rate risk. The fair value measurement of our derivatives was based on market prices that are generally observable for similar assets or liabilities at commonly-quoted intervals.

Note 3 - Derivative Instruments
    
Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar ("foreign currencies"). These transactions are remeasured in U.S. dollars based on a combination of both current and historical exchange rates. We use foreign currency forward contracts to reduce our exposure to various market risks, primarily foreign currency exchange rate risk.
 
All derivatives were recorded on our condensed consolidated balance sheets at fair value. Derivatives subject to legally enforceable master netting agreements were not offset in our condensed consolidated balance sheets. Accounting for the gains and losses resulting from changes in the fair value of derivatives depends on the use of the derivative and whether it qualifies for hedge accounting.  Net liabilities of $17.0 million and net assets of $1.8 million associated with our foreign currency forward contracts were included on our condensed consolidated balance sheets as of September 30, 2014 and December 31, 2013 , respectively.  All of our derivatives mature during the next 18 months .  See "Note 2 - Fair Value Measurements" for additional information on the fair value measurement of our derivatives.

(2)  	Derivative assets and liabilities that have maturity dates greater than twelve months from the respective balance sheet date were included in other assets, net, and other liabilities, respectively, on our condensed consolidated balance sheets.	
 
We utilize cash flow hedges to hedge forecasted foreign currency denominated transactions, primarily to reduce our exposure to foreign currency exchange rate risk associated with contract drilling expenses and capital expenditures denominated in various currencies. As of September 30, 2014 , we had cash flow hedges outstanding to exchange an aggregate $391.2 million for various foreign currencies, including $179.3 million for British pounds, $101.1 million for Brazilian reais, $38.2 million for euros, $32.1 million for Singapore dollars, $23.0 million for Australian dollars and $17.5 million for other currencies.

(2)	Gains and losses recognized in income for ineffectiveness and amounts excluded from effectiveness testing were included in other, net, in our condensed consolidated statements of operations.	

(3)	Losses on interest rate lock derivatives reclassified from AOCI into income (effective portion) were included in interest expense, net in our condensed consolidated statements of operations.	

(4)  	During the three-month period ended September 30, 2014 , $1.2 million of gains were reclassified from AOCI into contract drilling expense and $200,000 of gains were reclassified from AOCI into depreciation expense in our condensed consolidated statement of operations. During the three-month period ended September 30, 2013 , $2.9 million of losses were reclassified from AOCI into contract drilling expense and $200,000 of gains were reclassified from AOCI into depreciation expense in our condensed consolidated statement of operations.	

(5)  	During the nine-month period ended September 30, 2014 , $2.9 million of gains were reclassified from AOCI into contract drilling expense and $600,000 of gains were reclassified from AOCI into depreciation expense in our condensed consolidated statement of operations. During the nine-month period ended September 30, 2013 , $2.5 million  of losses were reclassified from AOCI into contract drilling expense and $600,000 of gains were reclassified from AOCI into depreciation expense in our condensed consolidated statement of operations.	

We have net assets and liabilities denominated in numerous foreign currencies and use various methods to manage our exposure to foreign currency exchange rate risk. We predominantly structure our drilling contracts in U.S. dollars, which significantly reduces the portion of our cash flows and assets denominated in foreign currencies. We occasionally enter into derivatives that hedge the fair value of recognized foreign currency denominated assets or liabilities but do not designate such derivatives as hedging instruments.  In these situations, a natural hedging relationship generally exists whereby changes in the fair value of the derivatives offset changes in the fair value of the underlying hedged items. As of September 30, 2014 , we held derivatives not designated as hedging instruments to exchange an aggregate $211.2 million for various foreign currencies, including $106.6 million for euros, $27.5 million for Swiss francs, $22.3 million for British pounds, $15.9 million for Indonesian rupiah, $14.3 million for Australian dollars and $24.6 million for other currencies.
     
Net losses of $15.4 million and net gains of $7.5 million associated with our derivatives not designated as hedging instruments were included in other, net, in our condensed consolidated statements of operations for the three-month periods ended September 30, 2014 and 2013 , respectively. Net losses of $15.1 million and net gains of $2.8 million associated with our derivatives not designated as hedging instruments were included in other, net in our condensed consolidated statements of operations for the nine-month periods ended September 30, 2014 and 2013 , respectively.

As of September 30, 2014 , the estimated amount of net  losses associated with derivative instruments, net of tax, that would be reclassified into earnings during the next twelve months totaled $3.4 million .

Note 4 - Noncontrolling Interests

Third parties hold a noncontrolling ownership interest in certain of our non-U.S. subsidiaries.

Note 6 - Debt

Senior Notes

On September 29, 2014, we issued $625.0 million aggregate principal amount of unsecured 4.50% senior notes due  2024 at a discount of $850,000 and $625.0 million aggregate principal amount of unsecured 5.75% senior notes due  2044 at a discount of $2.8 million (collectively the “2014 Notes”) in a public offering. Interest on the 2014 Notes is payable semiannually in April and October of each year commencing April 1, 2015.  The 2014 Notes were issued pursuant to an Indenture between us and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), dated March 17, 2011 (the “Indenture”) and a Second Supplemental Indenture between us and the Trustee, dated September 29, 2014 (the “2014 Supplemental Indenture”). We expect to use the net proceeds from this offering for general corporate purposes, which may include payments with respect to our rigs under construction and other capital expenditures. 

We may redeem each series of the 2014 Notes, in whole at any time or in part from time to time, prior to maturity. If we elect to redeem the 2014 Notes due 2024 before the date that is three months prior to the maturity date or the 2014 Notes due 2044 before the date that is six months prior to the maturity date, we will pay an amount equal to 100% of the principal amount of the notes redeemed plus accrued and unpaid interest and a “make-whole” premium. If we elect to redeem the 2014 Notes on or after the aforementioned dates, we will pay an amount equal to 100% of the principal amount of the notes redeemed plus accrued and unpaid interest, but are not required to pay a "make-whole" premium.

16

The 2014 Notes, the Indenture and the 2014 Supplemental Indenture also contain customary events of default, including failure to pay principal or interest on the 2014 Notes when due, among others. The 2014 Supplemental Indenture contains certain restrictions, including, among others, restrictions on our ability and the ability of our subsidiaries to create liens on certain assets, enter into certain sale-leaseback transactions, enter into certain merger or consolidation transactions or transfers of all or substantially all of our assets.
 
Five-Year Credit Facility

On September 30, 2014, we entered into an amendment to the Fourth Amended and Restated Credit Agreement (the "Five-Year Credit Facility"), among Ensco, Citibank, N.A., as Administrative Agent, DNB Bank ASA, as Syndication Agent, and a syndicate of banks. This amendment extended the Five-Year Credit Facility maturity date from May 7, 2018 to September 30, 2019 and increased the total commitment of the lenders from $2.0 billion to $2.25 billion . As amended, the Five-Year Credit Facility provides for a $2.25 billion senior unsecured revolving credit facility to be used for general corporate purposes.

Advances under the Five-Year Credit Facility bear interest at Base Rate or LIBOR plus an applicable margin rate (currently 0.125% per annum for Base Rate advances and 1.125% per annum for LIBOR advances) depending on our credit rating. Amounts repaid may be re-borrowed during the term of the Five-Year Credit Facility. We are required to pay a quarterly commitment fee (currently 0.125% per annum) on the undrawn portion of the $2.25 billion commitment, which is also based on our credit rating. In addition to other customary restrictive covenants, the Five-Year Credit Facility requires us to maintain a total debt to total capitalization ratio of less than or equal to 50% . We have the right, subject to lender consent, to increase the commitments under the Five-Year Credit Facility to an aggregate amount of up to $2.75 billion . We had no amounts outstanding under the Five-Year Credit Facility as of September 30, 2014 and December 31, 2013.

Note 7 - Impairment

Impairment of Long-Lived Assets

During the second quarter of 2014, demand for floaters deteriorated as a result of continued reduction in capital spending by operators in addition to recently announced delays in operators’ drilling programs. The reduction in demand, combined with the increasing supply from newbuild floater deliveries, led to a very competitive market. In general, contracting activity for floaters declined significantly, and new day rate fixtures were substantially lower than rates realized during the first quarter of 2014 and fourth quarter of 2013. More specifically, drilling contractors have been unable to contract older, less capable rigs as operators are now targeting premium, high-specification rigs at lower day rates. The significant supply and demand imbalance will continue to be adversely impacted by future newbuild deliveries, program delays and lower capital spending by operators. As a result, day rates and utilization will remain under pressure, especially for older, less capable floaters. In response to the adverse change in the current and anticipated floaters business climate, management evaluated our older, less capable floaters and committed to a plan to sell five rigs. These rigs were written down to fair value, less costs to sell, as of May 31, 2014 and classified as "held for sale" on our September 30, 2014 condensed consolidated balance sheet.

We measured the fair value of the "held for sale" rigs by applying a market approach, which was based on unobservable third-party estimated prices that would be received in exchange for the assets in an orderly transaction between market participants. We recorded a pre-tax, non-cash loss on impairment totaling $546.4 million during the nine-month period ended September 30, 2014 . The impairment charge was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . See "Note 9 - Discontinued Operations" for additional information on our "held for sale" rigs.

17

On a quarterly basis, we evaluate the carrying value of our property and equipment to identify events or changes in circumstances ("triggering events") that indicate the carrying value may not be recoverable. As a result of the adverse change in the floater business climate observed during the second quarter of 2014, management's commitment to a plan to sell five floaters during the second quarter of 2014 and the impairment charge incurred on the "held for sale" floaters, management concluded that a triggering event had occurred during the second quarter of 2014 and performed an asset impairment analysis on our remaining older, less capable floaters.

Based on the analysis performed as of May 31, 2014 , we recorded an additional non-cash loss on impairment with respect to four other floaters totaling $991.5 million . The impairment charge was included in loss on impairment in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . We measured the fair value of these rigs by applying an income approach, using projected discounted cash flows. These valuations were based on unobservable inputs that require significant judgments for which there is limited information, including assumptions regarding future day rates, utilization, operating costs and capital requirements.

Goodwill

Our business consists of three operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups and (3) Other, which consists of management services on rigs owned by third-parties. Our two reportable segments, Floaters and Jackups, provide one service, contract drilling.

We test goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists.  Management concluded that the aforementioned adverse change in the current and anticipated floater business climate, the commitment to a plan to sell five floaters and the impairment charge on the "held for sale" floaters triggered an interim impairment test to evaluate the Floaters reporting unit goodwill balance of $3.1 billion as of May 31, 2014 .

Based on the valuation performed as of May 31, 2014 , the Floaters reporting unit estimated fair value exceeded the carrying value (adjusted for the long-lived impairments noted above) by approximately 7% ; therefore, we concluded that the goodwill balance was not impaired.  We estimated the fair value of the Floaters reporting unit using a blended income and market approach.

The income approach was based on a discounted cash flow model, which utilized present values of cash flows to estimate fair value. The future cash flows were projected based on our estimates of future day rates, utilization, operating costs, capital requirements, growth rates and terminal values for our rigs. Forecasted day rates and utilization take into account current market conditions and our anticipated business outlook, both of which have been impacted by the recent adverse change in the floater business environment. The day rates reflected contracted rates during the respective contracted periods and management's estimate of market day rates in uncontracted periods. The forecasted market day rates were held constant in the near-term and were forecasted to grow in the longer-term and terminal period.

Operating costs were forecasted using our historical average operating costs and were adjusted for an estimated inflation factor. Capital requirements in the discounted cash flow model were based on management's estimates of future capital costs, taking into consideration our historical trends. The estimated capital requirements include cash outflows for new rig construction, rig enhancements and minor upgrades and improvements.

A terminal period was used to reflect our estimate of stable, perpetual growth. The terminal period reflects a terminal growth rate of 3.5% , which includes an estimated inflation factor. The future cash flows were discounted using a market-participant risk-adjusted weighted average cost of capital ("WACC") of 10.5% .

18

These assumptions were derived from unobservable inputs and reflect management's judgments and assumptions. A decline in the Floaters reporting unit cash flow projections or changes in other key assumptions may result in a goodwill impairment charge in the future. Specifically, keeping all other variables constant, a 50 basis point increase in the WACC applied would reduce the estimated fair value of our Floaters reporting unit below its carrying value. In addition, keeping all other variables constant, a 1.5% reduction in the terminal growth rate would reduce the estimated fair value of our Floaters reporting unit below its carrying value. Also, keeping all other variables constant, a 5.0% reduction in our forecasted market day rates would reduce the estimated fair value of our Floaters reporting unit below its carrying value.

The market approach was based upon the application of price-to-earnings multiples to management's estimates of future earnings adjusted for a control premium. The price-to-earnings multiples used in the market valuation ranged from 7.5 x to 8.5 x and were based on competitor market multiples. The fair value determined under the market approach is sensitive to these multiples, and a decline in any of the multiples could reduce the estimated fair value of our Floaters reporting unit below its carrying value. Management's earnings estimates were derived from unobservable inputs that require significant estimates, judgments and assumptions as described in the income approach.

The estimated fair value of the Floaters reporting unit determined under the income approach was consistent with the estimated fair value determined under the market approach. For purposes of the goodwill impairment test, we calculated the Floaters reporting unit estimated fair value as the average of the values calculated under the income approach and the market approach.

We evaluated the estimated fair value of our reporting units compared to our market capitalization as of May 31, 2014 . To perform this assessment, we used a market approach to estimate the fair value of the Jackups reporting unit. The aggregate fair values of our reporting units exceeded our market capitalization, and we believe the resulting implied control premium was reasonable based on recent market transactions within our industry or other relevant benchmark data.

Our stock price declined significantly during September and October 2014 reaching a twelve-month low of $35.96 on October 10th. Our stock price traded between $47.85 and $57.45 during the eight-month period ended August 2014. The average stock price for the three-month period ended September 30, 2014 was $49.01 , including average stock prices of $52.79 and $48.78 in July and August, respectively.

A sustained decline in our stock price is one of several qualitative factors we consider each quarter when evaluating whether events or changes in circumstances indicate that a potential goodwill impairment exists. We concluded that the decline in stock price observed in September and October did not represent a sustained decline and that no triggering events occurred during the third quarter requiring an interim goodwill impairment test as of September 30, 2014.

If our Floater operating performance or our Floater business outlook deteriorates and/or our stock trades at current levels for a sustained period, our Floaters reporting unit estimated fair value could decline below its carrying value, resulting in a goodwill impairment.

Factors that could have a negative impact on the fair value of the Floaters reporting unit include, but are not limited to:

•	decreases in estimated market day rates and utilization due to greater-than-expected market pressures, downtime and other risks associated with offshore rig operations;	

•	sustained decline in our stock price;	

•	decreases in revenue due to our inability to attract and retain skilled personnel;

•	changes in worldwide rig supply and demand, competition or technology, including changes as a result of delivery of newbuild drilling rigs;	

•	changes in future levels of drilling activity and expenditures, whether as a result of global capital markets and liquidity, prices of oil and natural gas or otherwise, which may cause us to idle or stack additional rigs;	

•	possible cancellation or suspension of drilling contracts as a result of mechanical difficulties, performance or other reasons;	

•	delays in actual contract commencement dates;	

•	the outcome of litigation, legal proceedings, investigations or other claims or contract disputes resulting in significant cash outflows;	

•	governmental, regulatory, legislative and permitting requirements affecting drilling operations, including limitations on drilling locations (such as the Gulf of Mexico during hurricane season);	

•	increases in the market-participant risk-adjusted WACC;	

•	declines in anticipated growth rates.	

Adverse changes in one or more of these factors could reduce the estimated fair value of our Floaters reporting unit below its carrying value in future periods.

Note 8 - Shareholders' Equity

During the three-month and nine-month periods ended September 30, 2014 , we granted 100,000 and 1.2 million non-vested share awards, respectively, to our employees, officers and non-employee directors for annual equity awards and for equity awards granted to new or recently promoted employees, pursuant to our 2012 Long-Term Incentive Plan. Grants of non-vested share awards generally vest at rates of 20% or 33% per year, as determined by a committee or subcommittee of the Board of Directors at the time of the grant. Our non-vested share awards have dividend rights effective on the date of grant and are measured at fair value using the market value of our shares on the date of grant. The weighted-average grant-date fair value of non-vested share awards granted during the three-month and nine-month periods ended September 30, 2014 was $51.31 and $52.48 per share, respectively.

Note 9 - Discontinued Operations
    
During the nine-month period ended September 30, 2014 , management committed to a plan to sell five floaters. The ENSCO 5000, ENSCO 5001, ENSCO 5002, ENSCO 6000 and ENSCO 7500 were removed from our portfolio of rigs marketed for contract drilling services and are being actively marketed for sale. These rigs were written down to fair value, less costs to sell, as of May 31, 2014 , and classified as "held for sale" on our September 30, 2014 condensed consolidated balance sheet.

We recorded a non-cash loss on impairment totaling $508.8 million , net of tax benefits of $37.6 million , during the nine-month period ended September 30, 2014 . The impairment charge was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . The operating results from these rigs were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2014 and 2013 .

Prior to the sale of ENSCO 7500, we will be required to pay the outstanding principal on the 6.36% MARAD bonds due 2015 collateralized by this rig. The outstanding principal balance on these bonds was $19.0 million as of September 30, 2014 . We recently provided notification to the indenture trustee for the 6.36% MARAD bonds due 2015 that we intend to make an optional redemption of these bonds in December 2014. The outstanding principal balance was included in current maturities of long-term debt on our condensed consolidated balance sheet as of September 30, 2014 .

20

During the nine-month period ended September 30, 2014 , we sold jackup rig ENSCO 85 for net proceeds of $64.4 million . The proceeds from the sale were included in investing activities of discontinued operations in our condensed consolidated statement of cash flows for the nine-month period ended September 30, 2014 . We recognized a gain of $2.3 million in connection with the disposal, which was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . ENSCO 85 operating results were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2014 and 2013 .

During the nine-month period ended September 30, 2014 , we sold jackup rigs ENSCO 69 and Wisconsin for net proceeds of $32.2 million . These rigs were classified as held for sale as of December 31, 2013 . The proceeds from the sale were received in December 2013 and included in net cash used in investing activities of discontinued operations in our consolidated statement of cash flows for the year ended December 31, 2013 , as updated. ENSCO 69 and Wisconsin operating results were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2014 and 2013 . We recognized a gain of $17.9 million in connection with the disposal, which was also included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 .

During the nine-month period ended September 30, 2013 , we sold jackup rig Pride Pennsylvania for net proceeds of $15.5 million . The proceeds from the sale were included in investing activities of discontinued operations in our condensed consolidated statement of cash flows for the nine-month period ended September 30, 2013 . We recognized a loss of $1.1 million in connection with the disposal, which was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2013 . Pride Pennsylvania operating results were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2013 .
    
The following table summarizes (loss) income from discontinued operations, net for the three-month and nine-month periods ended September 30, 2014 and 2013  (in millions):

																
 	Three Months Ended

Debt and interest expense are not allocated to our discontinued operations.

As of September 30, 2014 , the $289.0 million of assets classified as "held for sale" in other current assets on our condensed consolidated balance sheet primarily relates to the carrying values of five floaters.

Note 10 -	Income Taxes	
 
Our consolidated effective income tax rate for the three-month period ended September 30, 2014 was 12.6% as compared to 14.3% in the prior year quarter. Excluding the impact of discrete income tax items, our consolidated effective income tax rate for the three-month periods ended September 30, 2014 and 2013 was 12.7% and 13.7% , respectively.

Excluding the impact of the $991.5 million loss on impairment and discrete income tax expense, our consolidated effective income tax rate for the nine-month periods ended September 30, 2014 and 2013 was 11.6% and 12.6% , respectively. The decline in our effective tax rate for the three-month and nine-month periods is primarily attributable to an increase in the relative components of our earnings, excluding discrete items, generated in tax jurisdictions with lower tax rates.

Note 11 - Contingencies

ENSCO 29 Wreck Removal

During 2005, a portion of the ENSCO 29 platform drilling rig was lost over the side of a customer's platform as a result of Hurricane Katrina. In June 2014, we received a letter from an operator demanding that Ensco retrieve the derrick and drawworks from the seabed.
Our property insurance policies include coverage for ENSCO 29 wreckage and debris removal costs up to $3.8 million . We also maintain liability insurance policies that provide coverage under certain circumstances for wreckage and debris removal costs in excess of the $3.8 million coverage provided under the property insurance policies. We believe that it is not probable a liability exists with respect to this matter, and no liability has been recorded on our condensed consolidated balance sheet as of September 30, 2014 . While we cannot reasonably estimate a range of possible loss at this time, it is possible that removal costs may be in excess of our insurance coverage. Although we do not expect costs associated with the ENSCO 29 wreck removal to have a material adverse effect upon our financial position, operating results or cash flows, there can be no assurances as to the ultimate outcome.

ENSCO 74 Loss

During 2008, ENSCO 74 was lost as a result of Hurricane Ike in the U.S. Gulf of Mexico.  The sunken rig hull of ENSCO 74 was located approximately 95 miles from the original drilling location when it was struck by an oil tanker during 2009.  Wreck removal operations on the sunken rig hull of ENSCO 74 were completed during 2010.
 
We filed a petition for exoneration or limitation of liability under U.S. admiralty and maritime law during 2009. A number of claimants presented claims in the exoneration/limitation proceedings. We have liability insurance policies that provide coverage for such claims as well as removal of wreckage and debris in excess of the property insurance policy sublimit, subject to a $10.0 million per occurrence deductible for third-party claims and an annual aggregate limit of $490.0 million .

The owner of a pipeline filed claims alleging that ENSCO 74 caused the pipeline to rupture during Hurricane Ike and sought damages for the cost of repairs and business interruption in an amount in excess of $26.0 million . During the first quarter of 2014, we reached an agreement with the owner of the pipeline to settle the claims for $9.6 million . Prior to the settlement, we incurred legal fees of $3.6 million for this matter. During the second quarter of 2014, we paid the remaining $6.4 million of our deductible under our liability insurance policy, which was included in accrued liabilities and other on our condensed consolidated balance sheet as of December 31, 2013. The remaining $3.2 million of settlement proceeds was paid by our underwriters under the terms of the related insurance policies.

The owner of the oil tanker that struck the hull of ENSCO 74 filed claims seeking monetary damages in excess of $5.0 million for losses incurred when the tanker struck the sunken hull of ENSCO 74. This matter went to trial in June 2014, and the Company won a directed verdict on all claims. The plaintiff has the right to appeal the decision. We believe that it is not probable that a liability exists with respect to these claims.
 
We believe all liabilities associated with the ENSCO 74 loss during Hurricane Ike resulted from a single occurrence under the terms of the applicable insurance policies. However, legal counsel for certain liability underwriters have asserted that the liability claims arise from separate occurrences. In the event of multiple occurrences, the self-insured retention is $15.0 million for two occurrences and $1.0 million for each occurrence thereafter.

Although we do not expect final disposition of the claims associated with the ENSCO 74 loss to have a material adverse effect upon our financial position, operating results or cash flows, there can be no assurances as to the ultimate outcome.

22

Asbestos Litigation

We and certain subsidiaries have been named as defendants, along with numerous third-party companies as co-defendants, in multi-party lawsuits filed in Illinois, Mississippi, Texas, Louisiana and the UK by approximately 125 plaintiffs. The lawsuits seek an unspecified amount of monetary damages on behalf of individuals alleging personal injury or death, primarily under the Jones Act, purportedly resulting from exposure to asbestos on drilling rigs and associated facilities during the 1960s through the 1980s.

During 2013, we reached an agreement in principle with 58 of the plaintiffs to settle lawsuits filed in Mississippi for a nominal amount. While we believe the settlement will be approved by the Court, there can be no assurances as to the ultimate outcome.

We intend to vigorously defend against the remaining claims and have filed responsive pleadings preserving all defenses and challenges to jurisdiction and venue. However, discovery is still ongoing and, therefore, available information regarding the nature of all pending claims is limited. At present, we cannot reasonably determine how many of the claimants may have valid claims under the Jones Act or estimate a range of potential liability exposure, if any.
 
In addition to the pending cases in Mississippi and Louisiana, we have other asbestos or lung injury claims pending against us in litigation in other jurisdictions. Although we do not expect final disposition of these asbestos or lung injury lawsuits to have a material adverse effect upon our financial position, operating results or cash flows, there can be no assurances as to the ultimate outcome of the lawsuits.

   Other Matters

In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results or cash flows.

In the ordinary course of business with customers and others, we have entered into letters of credit and surety bonds to guarantee our performance as it relates to our drilling contracts, contract bidding, customs duties, tax appeals and other obligations in various jurisdictions. Letters of credit and surety bonds outstanding as of September 30, 2014 totaled $246.5 million and were issued under facilities provided by various banks and other financial institutions. Obligations under these letters of credit and surety bonds are not normally called as we typically comply with the underlying performance requirement. As of September 30, 2014 , we had not been required to make collateral deposits with respect to these agreements.

Note 12 - Sale-leaseback

In September 2014, we sold jackup rigs ENSCO 83, ENSCO 89, ENSCO 93 and ENSCO 98, all of which are contracted to Petroleos Mexicanos (“Pemex”). We received proceeds of $211.8 million and incurred commissions and other incremental, direct costs of $5.3 million . The carrying value of these rigs was $169.6 million .
In connection with this sale, we executed charter agreements with the purchaser to continue operating the rigs for the remainder of the Pemex contracts, which have anticipated completion dates in either late 2015 or 2016. We accounted for the transaction as a sale-leaseback, whereby we will retain a significant portion of the remaining use of the rigs as a result of the charter agreements.

23

We recorded a gain on sale of $7.5 million , which represents the portion of the gain that exceeded the present value of payments due under the charter agreements, included in contract drilling expense in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2014 . The remaining $29.4 million of gain was deferred and will be amortized to contract drilling expense within the Jackup segment over the remaining charter term of each rig. Of the $29.4 million deferred gain, $26.6 million is included in accrued liabilities and other and $2.8 million is included in other liabilities on our condensed consolidated balance sheet as of September 30, 2014.

The operating results from these rigs for the three-month and nine-month periods ended September 30, 2014 were included in income from continuing operations within the Jackup segment, as we expect to have significant continuing involvement and cash flows due to our charter agreements with the purchaser. Beginning October 1, 2014, the operating results for these rigs will be reported in our Other segment.

The $211.8 million of proceeds from the rig sales were invested directly in cash equivalents subject to certain restrictions on our ability to receive, pledge, borrow or otherwise obtain the funds as of September 30, 2014 . As a result of these restrictions, the sales proceeds are classified as restricted cash and included in other current assets on our condensed consolidated balance sheet as of September 30, 2014. We expect these restrictions to lapse prior to December 31, 2014.
  
Note 13 - Segment Information
 
Our business consists of three operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups and (3) Other, which consists of management services on rigs owned by third-parties. Our two reportable segments, Floaters and Jackups, provide one service, contract drilling.
    
Segment information for the three-month and nine-month periods ended 2014 and 2013 is presented below (in millions). General and administrative expense and depreciation expense incurred by our corporate office are not allocated to our operating segments for purposes of measuring segment operating income and were included in "Reconciling Items." We measure segment assets as property and equipment. Prior year information has been reclassified to conform to the current year presentation.

Consolidated Statement of Cash Flows Information

In September 2014, we sold jackup rigs ENSCO 83, ENSCO 89, ENSCO 93 and ENSCO 98, all of which are currently contracted to Pemex. The sale proceeds of $211.8 million were subject to certain restrictions as of September 30, 2014 and therefore were not included in our condensed consolidated statement of cash flows for the nine-month period ended September 30, 2014 .

Concentration of Risk

We are exposed to credit risk relating to our receivables from customers, our cash and cash equivalents, our short-term investments and our use of derivatives in connection with the management of foreign currency exchange rate risk. We mitigate our credit risk relating to receivables from customers, which consist primarily of major international, government-owned and independent oil and gas companies, by performing ongoing credit evaluations. We also maintain reserves for potential credit losses, which generally have been within management's expectations. We mitigate our credit risk relating to cash and cash equivalents by focusing on diversification and quality of instruments. Cash equivalents consist of a portfolio of high-grade instruments. Custody of cash and cash equivalents is maintained at several well-capitalized financial institutions, and we monitor the financial condition of those financial institutions.  

We mitigate our credit risk relating to counterparties of our derivatives through a variety of techniques, including transacting with multiple, high-quality financial institutions, thereby limiting our exposure to individual counterparties and by entering into International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreements, which include provisions for a legally enforceable master netting agreement, with almost all of our derivative counterparties. The terms of the ISDA agreements may also include credit support requirements, cross default provisions, termination events or set-off provisions.  Legally enforceable master netting agreements reduce credit risk by providing protection in bankruptcy in certain circumstances and generally permitting the closeout and netting of transactions with the same counterparty upon the occurrence of certain events.  See "Note 3 - Derivative Instruments" for additional information on our derivatives.

Item 2.   Management's Discussion and Analysis of Financial Condition and Results of Operations
    
Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the accompanying unaudited consolidated financial statements as of September 30, 2014 and for the three-month and nine-month periods ended September 30, 2014 and 2013 included elsewhere herein and with our annual report on Form 10-K for the year ended December 31, 2013 . The following discussion and analysis contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under “Risk Factors” in Item 1A of our annual report, as updated in our subsequent quarterly reports. See “Forward-Looking Statements.”

EXECUTIVE SUMMARY

Ensco owns the world's second largest offshore drilling rig fleet amongst competitive rigs. We operate one of the newest ultra-deepwater fleets in the industry, and our premium jackup fleet is the largest of any offshore drilling company. We currently own and operate an offshore drilling rig fleet of 71 rigs, including seven rigs under construction, spanning most of the strategic markets around the globe. Our fleet includes ten drillships, thirteen dynamically positioned semisubmersible rigs, six moored semisubmersible rigs and 42 jackup rigs.

The contracting environment remained very competitive during the third quarter, particularly in the Floaters segment, as a result of increasing rig supply combined with a reduction in capital spending by operators. We expect that day rates and utilization will remain under pressure, particularly for older, less capable floaters. Brent crude oil prices declined from $110 per barrel in July to near $90 per barrel at the end of the third quarter and continued to decline below $90 per barrel in October. It is uncertain how recent price declines will impact drilling programs as operators are currently preparing 2015 budgets. We believe current prices support planned projects, and that customers are assessing ways to more efficiently and economically manage their well programs rather than canceling these projects.

We remain focused on our long-established strategy of high-grading and expanding the size of our fleet where we identify long-term growth opportunities. In September, we sold four standard jackup rigs (ENSCO 83, ENSCO 89, ENSCO 93, and ENSCO 98). Additionally, five of our older, less capable floater rigs are currently being marketed for sale as part of our fleet high-grading strategy.

In response to customer demand for our differentiated rig technology and contract drilling services in the Middle East, we entered into an agreement with Lamprell plc to construct two premium jackup rigs (ENSCO 140 and ENSCO 141) during the second quarter. These rigs are scheduled for delivery during the second quarter and third quarter of 2016, respectively. In July, we accepted delivery of ENSCO 122, an ultra-premium harsh environment rig that is expected to be placed into service later this year. Currently, we have seven rigs under construction, including three ultra-deepwater drillships, three premium jackup rigs and one ultra-premium harsh environment jackup rig. In addition to ENSCO 122, our next two deliveries, ENSCO DS-9 and ENSCO DS-8, are contracted.

A significant portion of our projected cash flow will continue to be invested in the expansion and enhancement of our fleet. We also intend to continue paying quarterly dividends for the foreseeable future. However, our Board of Directors may change the timing and payment amount depending on several factors including our profitability, liquidity, financial condition, reinvestment opportunities and capital requirements.

During the third quarter, we completed a $1.25 billion debt offering and expanded the total commitments available under our revolving credit facility, increasing the total capacity from $2.0 billion to $2.25 billion . We believe our strong balance sheet, $10.9 billion of contract backlog, proceeds from the recent debt offering and borrowing capacity under our commercial paper program and revolving credit facility will provide flexibility to make additional investments in our fleet and sustain an adequate level of liquidity.

BUSINESS ENVIRONMENT
 
Floaters
    
The global contracting environment remains highly competitive, particularly for older, less capable floaters. A reduction in capital spending by operators, as well as increasing supply from newbuild floaters, has negatively impacted utilization and day rates. Operators have taken advantage of these lower rates by contracting premium and high-specification rigs. Drilling contractors are currently challenged to contract older, less capable floaters, although retirements could alleviate some of this pressure. We anticipate that the floater environment will remain competitive; however, we expect additional contracting opportunities to be available in several regions, particularly for premium rigs.

Rig supply in the U.S. Gulf of Mexico is expected to increase during the remainder of 2014 and into 2015 as multiple newbuild rigs mobilize to the region. Although the majority of these rigs are contracted, utilization and day rates for existing floaters in the region may be negatively impacted, causing some of these rigs to mobilize to other regions. We expect tendering activity to remain relatively low in the near-term; though past exploration successes and new discoveries could lead to incremental opportunities over time. In Mexico, ongoing energy reform could create future opportunities in the region.
 
In Brazil, we expect that near-term contracting activity will largely be driven by Petrobras, including incremental opportunities related to pre-salt development in the region. We believe there will also be incremental demand going forward as customers come to the market for rigs to drill their new exploration acreage awarded in licensing rounds held during 2013.

Customer demand remains strong in West Africa with multiple open tenders for rigs with multi-year terms. Incremental opportunities are expected in Angola, Ghana and Nigeria, and several operators have exploration programs planned in East Africa and South Africa. Going forward, there could be downward pressure on contracting terms if drilling contractors elect to move additional rigs into the region.

Supply and demand in the North Sea market are balanced, though available supply from the Norwegian sector may put downward pressure on the UK market. We expect additional drilling opportunities in the Mediterranean market, particularly for rigs with higher technical specifications and strong operational track records. In Asia Pacific, we anticipate incremental requirements in Australia, Indonesia and Vietnam.

The worldwide supply of floaters continues to increase as a result of newbuild construction programs. Currently, there are approximately 85 competitive newbuild drillships and semisubmersible rigs reported to be under construction, of which approximately 40 are without contracts. We estimate that six rigs will be delivered before the end of 2014, half of which are uncontracted. Utilization and day rates will likely continue to be negatively impacted, particularly for less capable floaters.
 
Jackups

Demand for jackups remains stable, generally supporting current day rates and contract terms. However, newbuild deliveries have caused downward pressure on new contracting activity in certain regions. Utilization and day rates may come under additional pressure as more newbuild rigs enter the market; however, retirements of older jackups could partially offset new supply, as the majority of the global jackup fleet is more than 30 years old.
In the U.S. Gulf of Mexico, customer demand has declined. Recent contract terms have declined in duration, which has put pressure on day rates and utilization, particularly for less capable units. In Mexico, we believe there will be incremental demand as the national oil company of Mexico, Petróleos Mexicanos ("PEMEX"), continues to expand its rig fleet.

43

The Middle East market is expected to remain strong, and we believe there will be incremental demand from operators in the region as well as opportunities to extend existing contracts. In West Africa, there are currently open tenders for incremental rigs for multi-year terms, though recent contracting activity has resulted in some downward pressure on day rates.

Customer demand for jackups remains strong in the North Sea market, though supply and demand dynamics have caused downward pressure in Norway. Significant contracted backlog exists for the remainder of 2014, and operators are issuing tenders to secure rigs for work during 2015 and beyond.

Demand remains steady in the Asia Pacific market, though recent contracting activity indicates an increasingly competitive environment due to available rig supply. We expect further pressure on utilization and day rates as multiple uncontracted newbuild rigs are added to the rig supply in the region. Drilling contractors may seek opportunities to move rigs out of the region. We expect several tenders to be issued in the coming months for multi-year programs in Malaysia, Vietnam and Indonesia commencing during 2015, which could help absorb the incremental newbuilds added to the Asia Pacific fleet.

Worldwide jackup supply continues to increase as a result of ongoing construction programs. Currently, there are approximately 130 competitive newbuild jackup rigs reported to be under construction, approximately half of which are being built by companies that have not historically operated offshore drilling rigs. Twelve rigs are scheduled for delivery during the remainder of 2014, the majority of which are not contracted. While customer demand remains positive, utilization and day rates in certain regions may come under additional pressure in the near-term, depending upon the rate at which older jackups are retired.

RESULTS OF OPERATIONS
 
The following table summarizes our condensed consolidated results of operations for the three-month and nine-month periods ended September 30, 2014 and 2013 (in millions):

Net income (loss) attributable to Ensco	$	429.4		 	$	378.8		 	$	(450.8	)	 	$	1,056.8		
 
Revenues increased $99.0 million , or 9% , and contract drilling expense declined $2.9 million , or 1% , for the three-month period ended September 30, 2014 as compared to the prior year quarter. The increase in revenues was primarily due to the addition of newbuild rigs to both our Floaters and Jackups segments and an increase in average day rates, partially offset by a decline in utilization.

44

For the nine-month period ended September 30, 2014 , revenues increased $261.3 million , or 8% , and contract drilling expense increased $118.7 million , or 8% , as compared to the prior year period. The increase in revenues was primarily due to the addition of newbuild rigs to both our Floaters and Jackups segments and an increase in average day rates, partially offset by a decline in utilization. The increase in contract drilling expense was due to the aforementioned additions to our fleet and higher personnel and repair and maintenance costs. Contract drilling expense for the nine-month period ended September 30, 2013 included a provision for doubtful accounts related to OGX receivables.

During the nine-month period ended September 30, 2014 , we recorded a non-cash loss on impairment with respect to four older, less capable rigs in our Floaters segment totaling $991.5 million . See below for additional information on our results by segment.
 
A significant number of our drilling contracts are of a long-term nature. Accordingly, an increase or decline in demand for contract drilling services generally affects our operating results and cash flows gradually over future quarters as long-term contracts expire and new contracts and/or options are priced at current market rates.

Rig Counts, Utilization and Average Day Rates
 
The following table summarizes our offshore drilling rigs by reportable segment and rigs under construction as of September 30, 2014 and 2013 :

Floaters (1)	26	 	26	
Jackups (2)(3)	38	 	43	
Under construction (2)(4)	7	 	6	
Total	71	 	75	

(1)  	The five floaters classified as "held for sale" as of September 30, 2014 are included in the table above.	

(2)  	During the fourth quarter of 2013 and third quarter of 2014, we accepted delivery of two ultra-premium harsh environment jackup rigs, ENSCO 121 and ENSCO 122, respectively. ENSCO 121 commenced drilling operations under a long-term contract during the second quarter of 2014. ENSCO 122 is committed under a long-term drilling contract expected to commence later this year.	

(3)  	We sold jackup rigs ENSCO 69 and Pride Wisconsin during the first quarter of 2014 and ENSCO 85 during the second quarter of 2014. During the third quarter of 2014, we sold jackup rigs ENSCO 83, ENSCO 89, ENSCO 93 and ENSCO 98.	

(4)  	During the fourth quarter of 2013, we entered into an agreement with Keppel FELS Limited ("KFELS") to construct an ultra-premium harsh environment jackup rig (ENSCO 123). This rig is scheduled for delivery during the second quarter of 2016 and is currently uncontracted. During the second quarter of 2014, we entered into an agreement with Lamprell plc to construct two premium jackup rigs, ENSCO 140 and ENSCO 141, which are scheduled for delivery during the second quarter and third quarter of 2016, respectively. Both of these rigs remain uncontracted.

Jackups	136,588		 	125,257		 	134,095		 	121,276		
Total	$	236,736		 	$	224,640		 	$	238,842		 	$	219,398		

(1)  	Rig utilization is derived by dividing the number of days under contract by the number of days in the period. Days under contract equals the total number of days that rigs have earned and recognized day rate revenue, including days associated with compensated downtime and mobilizations. When revenue is earned but is deferred and amortized over a future period, for example when a rig earns revenue while mobilizing to commence a new contract or while being upgraded in a shipyard, the related days are excluded from days under contract.	

For newly-constructed or acquired rigs, the number of days in the period begins upon commencement of drilling operations for rigs with a contract or when the rig becomes available for drilling operations for rigs without a contract.

(2)  	Average day rates are derived by dividing contract drilling revenues, adjusted to exclude certain types of non-recurring reimbursable revenues, lump sum revenues and revenues attributable to amortization of drilling contract intangibles, by the aggregate number of contract days, adjusted to exclude contract days associated with certain mobilizations, demobilizations, shipyard contracts and standby contracts.  	

Detailed explanations of our operating results, including discussions of revenues, contract drilling expense and depreciation expense by segment, are provided below.

Operating Income
 
Our business consists of three operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups and (3) Other, which currently consists of management services on rigs owned by third-parties. Our two reportable segments, Floaters and Jackups, provide one service, contract drilling.
Segment information is presented below (in millions).  General and administrative expense and depreciation expense incurred by our corporate office are not allocated to our operating segments for purposes of measuring segment operating income and were included in "Reconciling Items." Prior year information has been reclassified to conform to the current year presentation.

Floaters

Floater revenues for the three-month period ended September 30, 2014 increased $48.6 million , or 7% , compared to the prior year quarter primarily due to ENSCO DS-7, which commenced its initial drilling contract during the fourth quarter of 2013.

Floater contract drilling expense for the three-month period ended September 30, 2014 declined $5.7 million , or 2% , compared to the prior year quarter due to lower windstorm insurance costs and lower costs on ENSCO 5006 which was in the shipyard for a capital enhancement project during 2014. These declines were partially offset by the addition of ENSCO DS-7. Contract drilling expense for the three-month period ended September 30, 2013 also included an $11.0 million provision for doubtful accounts related to OGX receivables.

Depreciation expense was comparable to the prior year quarter. The increase in depreciation due to the addition of ENSCO DS-7 to the fleet was offset by lower depreciation expense as a result of the impairments recorded during the second quarter of 2014.

Floater revenues for the nine-month period ended September 30, 2014 increased by $117.2 million , or 6% , as compared to the prior year period. The increase in revenues was primarily due to commencement of the ENSCO DS-7 drilling contract during the fourth quarter of 2013 and an increase in average day rates across our Floater fleet. These increases were partially offset by a decline in utilization attributable to certain rigs in our Floater fleet. ENSCO 5004 and ENSCO 5006 were in the shipyard for capital enhancement projects during 2014, and ENSCO 8503 incurred several months of uncontracted downtime primarily during the first quarter. Utilization in the prior year period was negatively impacted by downtime prompted by a vendor notice regarding inspection and replacement of connector bolts on various rigs, as well as inspection related downtime on ENSCO DS-2.

Floater contract drilling expense for the nine-month period ended September 30, 2014 increased by $77.5 million , or 9% , as compared to the prior year period, primarily due to the aforementioned addition of DS-7 to our Floater fleet. To a lesser extent, higher personnel and repair and maintenance costs also contributed to the increase in contract drilling expense. These increases were partially offset by lower contract drilling expense for the ENSCO 5006 and lower windstorm insurance costs. Contract drilling expense for the nine-month period ended September 30, 2013 also included the aforementioned provision for doubtful accounts related to OGX receivables.

We recognized a loss on impairment of $991.5 million during the nine-month period ended September 30, 2014 related to four older, less capable floaters due to the adverse change in the current and anticipated market for these assets. No impairments were recorded during the prior year period.

Depreciation expense increased by $10.1 million , or 4% , primarily due to the addition of DS-7 to our Floater fleet, partially offset by lower depreciation as a result of the impairments recorded during the second quarter of 2014.

Jackups

Jackup revenues for the three-month period ended September 30, 2014 increased by $52.2 million , or 12% , as compared to the prior year quarter primarily due to commencement of the ENSCO 120 and ENSCO 121 drilling contracts during the first quarter and second quarter of 2014, respectively, and an increase in average day rates across our Jackup fleet. These increases were partially offset by a decline in utilization for certain rigs in the Jackup fleet.
Jackup contract drilling expense for the three-month period ended September 30, 2014 increased $6.4 million , or 3% , as compared to the prior year quarter due to the aforementioned additions to our Jackup fleet. These increases were partially offset by the gain recognized on the sale of ENSCO 83, ENSCO 89, ENSCO 93 and ENSCO 98. Depreciation expense increased by $8.1 million , or 21% , primarily due to the additions to our Jackup fleet.

48

Jackup revenues for the nine-month period ended September 30, 2014 increased by $153.3 million , or 12% , as compared to the prior year period. The increase in revenues was primarily due to an increase in average day rates across our Jackup fleet and commencement of the ENSCO 120 and ENSCO 121 drilling contracts. These increases were partially offset by a decline in utilization for certain rigs in the Jackup fleet.

Jackup contract drilling expense for the nine-month period ended September 30, 2014 increased $53.5 million , or 9% , as compared to the prior year period due to the aforementioned additions to our Jackup fleet and an increase in personnel and repair and maintenance costs. Depreciation expense increased by $15.8 million , or 14% , primarily due to the additions to our Jackup fleet.
 
Reconciling Items

General and administrative expenses declined $8.1 million , or 22% , and $8.0 million , or 7% , for the three-month and nine-month periods ended September 30, 2014 , respectively, as compared to the prior year periods primarily due to lower incentive compensation and burden costs.

Other Income (Expense)
 
The following table summarizes other income (expense) for the three-month and nine-month periods ended September 30, 2014 and 2013  (in millions):

																
 	Three Months Ended

 	$	(38.4	)	 	$	(1.6	)	 	$	(98.3	)	 	$	(71.2	)	
 
Interest income for the three-month and nine-month periods ended September 30, 2014 declined as compared to the respective prior year periods primarily due to declining outstanding principal amounts for reimbursement of mobilization and upgrade costs on certain long-term drilling contracts due from customers.

Interest expense was comparable over the same periods as the average outstanding principal balances associated with our long-term debt instruments remained consistent. The $1.25 billion debt offering was completed on September 29, 2014 and therefore did not have a significant impact on interest expense for the three-month and nine-month periods ended September 30, 2014 . Interest expense capitalized during the three-month and nine-month periods ended September 30, 2014 increased as compared to the prior year periods due to an increase in the average outstanding amount of capital invested in newbuild construction.

Our functional currency is the U.S. dollar, and a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar ("foreign currencies"). These transactions are remeasured in U.S. dollars based on a combination of both current and historical exchange rates. Net foreign currency exchange losses of $2.5 million and $900,000 were included in other, net for the three-month and nine-month periods ended September 30, 2014 , respectively. Net foreign currency exchange gains of $2.2 million and $7.0 million were included in other, net for the three-month and nine-month periods ended September 30, 2013 , respectively. The $7.0 million net foreign currency exchange gain for the nine-month period ended September 30, 2013 was primarily attributable to devaluation of the Venezuelan Bolivar.

Net unrealized losses of $500,000 and net unrealized gains of $1.0 million from marketable securities held in our SERP were included in other, net in our condensed consolidated statements of operations for the three-month and nine-month periods ended September 30, 2014 , respectively. Net unrealized gains of $2.0 million and $4.2 million from marketable securities held in our SERP were included in other, net in our condensed consolidated statements of operations for the three-month and nine-month periods ended September 30, 2013 , respectively. The fair value measurement of our marketable securities held in the SERP is discussed in Note 2 to our condensed consolidated financial statements.

During the three-month period ended September 30, 2013 , we received a $30.6 million reimbursement from the Mexican tax authority with respect to the tax authority's draw on letters of credit issued by an Ensco subsidiary for the benefit of Seahawk under a credit support agreement executed in connection with the 2009 spin-off of Seahawk. The reimbursement was included in other, net in our condensed consolidated statements of income for the three-month and nine-month periods ended September 30, 2013 .

Provision for Income Taxes
 
Ensco plc, our parent company, is domiciled and resident in the U.K. Our subsidiaries conduct operations and earn income in numerous countries and are subject to the laws of taxing jurisdictions within those countries. The income of our non-U.K. subsidiaries is not subject to U.K. taxation. Income tax rates imposed in the tax jurisdictions in which our subsidiaries conduct operations vary, as does the tax base to which the rates are applied. In some cases, tax rates may be applicable to gross revenues, statutory or negotiated deemed profits or other bases utilized under local tax laws, rather than to net income. Our drilling rigs frequently move from one taxing jurisdiction to another to perform contract drilling services. In some instances, the movement of drilling rigs among taxing jurisdictions will involve the transfer of ownership of the drilling rigs among our subsidiaries. As a result of frequent changes in the taxing jurisdictions in which our drilling rigs are operated and/or owned, changes in the overall level of our income and changes in tax laws, our consolidated effective income tax rate may vary substantially from one reporting period to another.
Income tax expense for the three-month periods ended September 30, 2014 and 2013 was $65.5 million and $65.4 million , respectively. Income tax expense for the nine-month periods ended September 30, 2014 and 2013 was $166.4 million and 164.7 million , respectively.
Our consolidated effective income tax rate for the three-month period ended September 30, 2014 was 12.6% as compared to 14.3% in the prior year quarter. Excluding the impact of discrete income tax items, our consolidated effective income tax rate for the three-month periods ended September 30, 2014 and 2013 was 12.7% and 13.7% , respectively.
Excluding the impact of the $991.5 million loss on impairment and discrete income tax expense, our consolidated effective income tax rate for the nine-month periods ended September 30, 2014 and 2013 was 11.6% and 12.6% , respectively. The decline in our effective tax rate for the three-month and nine-month periods is primarily attributable to an increase in the relative components of our earnings, excluding discrete items, generated in tax jurisdictions with lower tax rates.     
Discontinued Operations

During the nine-month period ended September 30, 2014 , management committed to a plan to sell five floaters. The ENSCO 5000, ENSCO 5001, ENSCO 5002, ENSCO 6000 and ENSCO 7500 were removed from our portfolio of rigs marketed for contract drilling services and are being actively marketed for sale. These rigs were written down to fair value, less costs to sell, as of May 31, 2014 , and classified as "held for sale" on our September 30, 2014 condensed consolidated balance sheet.

50

We recorded a non-cash loss on impairment totaling $508.8 million , net of tax benefits of $37.6 million , during the nine-month period ended September 30, 2014 . The impairment charge was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . The operating results from these rigs were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2014 and 2013 .

Prior to the sale of ENSCO 7500, we will be required to pay the outstanding principal on the 6.36% MARAD bonds due 2015 collateralized by this rig. The outstanding principal balance on these bonds was $19.0 million as of September 30, 2014 . We recently provided notification to the indenture trustee for the 6.36% MARAD bonds due 2015 that we intend to make an optional redemption of these bonds in December 2014. The outstanding principal balance was included in current maturities of long-term debt on our condensed consolidated balance sheet as of September 30, 2014 .

During the nine-month period ended September 30, 2014 , we sold jackup rig ENSCO 85 for net proceeds of $64.4 million . The proceeds from the sale were included in investing activities of discontinued operations in our condensed consolidated statement of cash flows for the nine-month period ended September 30, 2014 . We recognized a gain of $2.3 million in connection with the disposal, which was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . ENSCO 85 operating results were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2014 and 2013 .

During the nine-month period ended September 30, 2014 , we sold jackup rigs ENSCO 69 and Wisconsin for net proceeds of $32.2 million . These rigs were classified as held for sale as of December 31, 2013 . The proceeds from the sale were received in December 2013 and included in net cash used in investing activities of discontinued operations in our consolidated statement of cash flows for the year ended December 31, 2013 , as updated. ENSCO 69 and Wisconsin operating results were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2014 and 2013 . We recognized a gain of $17.9 million in connection with the disposal, which was also included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 .

During the nine-month period ended September 30, 2013 , we sold jackup rig Pride Pennsylvania for net proceeds of $15.5 million . The proceeds from the sale were included in investing activities of discontinued operations in our condensed consolidated statement of cash flows for the nine-month period ended September 30, 2013 . We recognized a loss of $1.1 million in connection with the disposal, which was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2013 . Pride Pennsylvania operating results were included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2013 .
        
LIQUIDITY AND CAPITAL RESOURCES

Although our business is cyclical, we have historically relied on our cash flow from continuing operations to meet liquidity needs and fund the majority of our cash requirements. We have maintained a strong financial position through the disciplined and conservative use of debt, which has provided us the ability to achieve future growth potential through acquisitions and newbuild rig construction. A substantial portion of our cash flow has been invested in the expansion and enhancement of our fleet of drilling rigs through newbuild construction and upgrade projects and the return of capital to shareholders through dividend payments.

51

A significant portion of our projected cash flow will continue to be invested in the expansion and enhancement of our fleet. We also intend to continue paying quarterly dividends for the foreseeable future. However, our Board of Directors may change the timing and payment amount depending on several factors including our profitability, liquidity, financial condition, reinvestment opportunities and capital requirements. Based on our balance sheet and contractual backlog of $10.9 billion , we believe future capital projects, debt service and dividend payments will primarily be funded from cash and cash equivalents, future operating cash flows and borrowings under our commercial paper program and/or revolving credit facility. We may decide to access debt and/or equity markets to raise additional capital or increase liquidity as necessary.

During the nine-month period ended September 30, 2014 , our primary source of cash was $1.6 billion generated from operating activities of continuing operations and $1.2 billion in proceeds from our September debt issuance. Our primary use of cash for the same period was $1.2 billion for the construction, enhancement and other improvement of our drilling rigs and  $526.7 million for dividend payments.

During the nine-month period ended September 30, 2013 , our primary source of cash was $1.3 billion generated from operating activities of continuing operations and $50.0 million in proceeds from the maturity of short-term investments. Our primary use of cash for the same period was $1.3 billion for the construction, enhancement and other improvement of our drilling rigs and  $350.2 million for dividend payments.

Cash Flow and Capital Expenditures
 
Our cash flow from operating activities of continuing operations and capital expenditures for the nine-month periods ended September 30, 2014 and 2013 were as follows (in millions):

								
 	2014	 	2013	
Cash flow from operating activities of continuing operations	$	1,585.3		 	$	1,349.4		
Capital expenditures	 		 	 		
New rig construction	$	574.5		 	$	897.0		
Rig enhancements	417.4		 	195.2		
Minor upgrades and improvements	255.1		 	181.4		
 	$	1,247.0		 	$	1,273.6		
    
Cash flow from operating activities of continuing operations increased $235.9 million , or 17% , for the nine-month period ended September 30, 2014 as compared to the prior year period. The increase primarily resulted from a $400.4 million increase in cash receipts from contract drilling services and a $23.6 million decline in cash payments for interest, partially offset by a $203.7 million increase in cash payments related to contract drilling expenses.

We remain focused on our long-established strategy of high-grading and expanding the size of our fleet where we identify long-term growth opportunities. In response to customer demand for our differentiated rig technology and contract drilling services in the Middle East, we entered into an agreement with Lamprell plc to construct two premium jackup rigs (ENSCO 140 and ENSCO 141) during the second quarter of 2014. ENSCO 140 and ENSCO 141 are significantly enhanced versions of the LeTorneau Super 116E jackup design and will incorporate Ensco's patented Canti-Leverage Advantage SM technology. These rigs are scheduled for delivery during the second quarter and the third quarter of 2016, respectively.

During 2013, we entered into agreements with KFELS to construct a premium jackup rig (ENSCO 110) and an ultra-premium harsh environment jackup rig (ENSCO 123). These rigs are scheduled for delivery during the first quarter of 2015 and the second quarter of 2016, respectively. Both of these rigs are currently uncontracted.

52

We previously entered into agreements with KFELS to construct three ultra-premium harsh environment jackup rigs (ENSCO 120, ENSCO 121 and ENSCO 122). ENSCO 122 was delivered during the third quarter of 2014 and is committed under a long-term drilling contract expected to commence later this year. ENSCO 121 was delivered during the fourth quarter of 2013 and commenced drilling operations under a long-term contract in the North Sea during the second quarter of 2014. ENSCO 120 was delivered during the third quarter of 2013 and commenced drilling operations under a long-term contract in the North Sea during the first quarter of 2014.

We currently have three ultra-deepwater drillships under construction (ENSCO DS-8, ENSCO DS-9 and ENSCO DS-10). ENSCO DS-9 and ENSCO DS-8 are committed under long-term contracts and currently scheduled for delivery during the first quarter and second quarter of 2015, respectively. ENSCO DS-10 is currently uncontracted and scheduled for delivery during the third quarter of 2015.

A significant portion of our projected cash flow will continue to be invested in the expansion and enhancement of our fleet of drilling rigs. We also intend to continue paying quarterly dividends for the foreseeable future. However, our Board of Directors may change the timing and payment amount depending on several factors including our profitability, liquidity, financial condition, reinvestment opportunities and capital requirements. We believe our strong balance sheet, $10.9 billion of contract backlog, proceeds from the recent debt offering and borrowing capacity under our commercial paper program and revolving credit facility will provide flexibility to make additional investments in our fleet and sustain an adequate level of liquidity.
 
The following table summarizes the cumulative amount of contractual payments made as of September 30, 2014 for our rigs under construction and estimated timing of our remaining contractual payments (in millions):

																					
 	 	Cumulative Paid (1)	 	Remaining 2014	 	2015	 	2016	 	Total (2)	
ENSCO DS-8	 	161.4		 	—		 	384.1		 	—		 	545.5		
ENSCO DS-9	 	157.4		 	—		 	375.8		 	—		 	533.2		
ENSCO DS-10	 	206.0		 	—		 	308.3		 	—		 	514.3		
ENSCO 110	 	41.0		 	—		 	166.2		 	—		 	207.2		
ENSCO 123	 	53.5		 	—		 	214.3		 	—		 	267.8		
ENSCO 140	 	39.2		 	39.2		 	78.0		 	39.2		 	195.6		
ENSCO 141	 	39.2		 	—		 	118.2		 	39.2		 	196.6		
 	 	$	697.7		 	$	39.2		 	$	1,644.9		 	$	78.4		 	$	2,460.2		

(1)  	Cumulative paid represents the aggregate amount of contractual payments made from commencement of the construction agreement through September 30, 2014 .	

(2)  	Total commitments are based on fixed-price shipyard construction contracts, exclusive of costs associated with commissioning, systems integration testing, project management and capitalized interest.	

Future contractual payments for rig enhancement projects, which are not reflected in the table above, were $72.5 million as of September 30, 2014 . We currently estimate these payments will be made during the next 12 months.

The actual timing of these expenditures may vary based on the completion of various construction milestones, which are, to a large extent, beyond our control.

Based on our current projections, we expect capital expenditures during 2014 to include approximately $750 million for newbuild construction, approximately $560 million for rig enhancement projects and approximately  $340 million for minor upgrades and improvements. Depending on market conditions and future opportunities, we may make additional capital expenditures to upgrade rigs for customer requirements and construct or acquire additional rigs.

Interest on the 2014 Notes is payable semiannually in April and October of each year commencing April 1, 2015.  The 2014 Notes were issued pursuant to an Indenture between us and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), dated March 17, 2011 and a Second Supplemental Indenture between us and the Trustee, dated September 29, 2014 (the “2014 Supplemental Indenture”). We expect to use the net proceeds from this offering for general corporate purposes, which may include payments with respect to our rigs under construction and other capital expenditures. 
    
As of September 30, 2014 , in addition to the 2014 Notes, we had outstanding $1.0 billion aggregate principal amount of unsecured 3.25% senior notes due 2016, $500.0 million aggregate principal amount of unsecured 8.5% senior notes due 2019, $900.0 million aggregate principal amount of unsecured 6.875% senior notes due 2020, $1.5 billion aggregate principal amount of unsecured 4.7% senior notes due 2021 and $300.0 million aggregate principal amount of unsecured 7.875% senior notes due 2040. As of September 30, 2014 , we also had outstanding $150.0 million aggregate principal amount of unsecured 7.2% debentures due 2027. We make semiannual interest payments on each of the aforementioned notes and debentures.

Revolving Credit

On September 30, 2014, we entered into an amendment to the Fourth Amended and Restated Credit Agreement (the "Five-Year Credit Facility"), among Ensco, Citibank, N.A., as Administrative Agent, DNB Bank ASA, as Syndication Agent, and a syndicate of banks. This amendment extended the Five-Year Credit Facility maturity date from May 7, 2018 to September 30, 2019 and increased the total commitment of the lenders from $2.0 billion to $2.25 billion . As amended, the Five-Year Credit Facility provides for a $2.25 billion senior unsecured revolving credit facility to be used for general corporate purposes.

Advances under the Five-Year Credit Facility bear interest at Base Rate or LIBOR plus an applicable margin rate (currently 0.125% per annum for Base Rate advances and 1.125% per annum for LIBOR advances) depending on our credit rating. Amounts repaid may be re-borrowed during the term of the Five-Year Credit Facility. We are required to pay a quarterly commitment fee (currently 0.125% per annum) on the undrawn portion of the $2.25 billion commitment, which is also based on our credit rating. In addition to other customary restrictive covenants, the Five-Year Credit Facility requires us to maintain a total debt to total capitalization ratio of less than or equal to 50% . We have the right, subject to lender consent, to increase the commitments under the Five-Year Credit Facility to an aggregate amount of up to $2.75 billion . We had no amounts outstanding under the Five-Year Credit Facility as of September 30, 2014 and December 31, 2013.

Commercial Paper
 
We participate in a commercial paper program with four commercial paper dealers pursuant to which we may issue, on a private placement basis, unsecured commercial paper notes. During the second quarter of 2014, we increased the size of our program to permit the issuance of commercial paper notes in an aggregate principal amount not to exceed $2.0 billion at any time outstanding. Amounts issued under the commercial paper program are supported by the available and unused committed capacity under our credit facility. As a result, amounts issued under the commercial paper program are limited by the amount of our available and unused committed capacity under our credit facility. The proceeds of such financings may be used for capital expenditures and other general corporate purposes. The commercial paper bears interest at rates that vary based on market conditions and the ratings assigned by credit rating agencies at the time of issuance. The commercial paper maturities will vary but may not exceed 364 days from the date of issuance. The commercial paper is not redeemable or subject to voluntary prepayment by us prior to maturity. We had no amounts outstanding under our commercial paper program as of September 30, 2014 and December 31, 2013 .
      
Other Financing

As of September 30, 2014 , we had $103.3 million outstanding under our Maritime Administration bond issues, $19.0 million of which is due in December 2015. The remaining $84.3 million outstanding is due in 2016 and 2020. We make semiannual principal and interest payments on these bonds. The $19.0 million due in December 2015 is outstanding principal on the 6.36% MARAD bonds collateralized by ENSCO 7500. Prior to the sale of this rig, we will be required to pay the outstanding principal. We recently provided notification to the indenture trustee for the 6.36% MARAD bonds due 2015 that we intend to make an optional redemption of these bonds in December 2014. The outstanding principal balance was included in current maturities of long-term debt on our condensed consolidated balance sheet as of September 30, 2014 .

We filed an automatically effective shelf registration statement on Form S-3 with the U.S. Securities and Exchange Commission ("SEC") on January 13, 2012, which provides us the ability to issue debt securities, equity securities, guarantees and/or units of securities in one or more offerings. The registration statement, as amended, expires in January 2015.

During 2013, our shareholders approved a new share repurchase program. Subject to certain provisions under English law, including the requirement of Ensco plc to have sufficient distributable reserves, we may purchase up to a maximum of $2.0 billion in the aggregate under the program, but in no case more than 35.0 million shares. The program terminates in May 2018.

Other Commitments

As of September 30, 2014 , we were contingently liable in the aggregate amount of $246.5 million under outstanding letters of credit and surety bonds which guarantee our performance as it relates to our drilling contracts, contract bidding, customs duties, tax appeals and other obligations in various jurisdictions. Obligations under these letters of credit and surety bonds are not normally called, as we typically comply with the underlying performance requirement. As of September 30, 2014 , we had not been required to make any collateral deposits with respect to these agreements.

Short-term investments	45.3		 	50.0		
Working capital	1,898.9		 	487.9		
Current ratio	2.7		 	1.5		

We expect to fund our short-term liquidity needs, including contractual obligations and anticipated capital expenditures, as well as dividends or working capital requirements, from our cash and cash equivalents, restricted cash, short-term investments, operating cash flows, and, if necessary, funds borrowed under our commercial paper program or revolving credit facility. We may decide to access debt and/or equity markets to raise additional capital or increase liquidity as necessary.

We expect to fund our long-term liquidity needs, including contractual obligations, anticipated capital expenditures and dividends, from our operating cash flows and, if necessary, funds borrowed under our revolving credit facility or other future financing arrangements. We may decide to access debt and/or equity markets to raise additional capital or increase liquidity as necessary.
 
Capital Reorganization

In June 2014, we completed a capital reorganization under UK law (the “Capital Reorganization”), which will provide the Company with greater flexibility going forward to return capital to shareholders in the form of dividends and share repurchases. The Capital Reorganization, which was authorized by our Board of Directors and approved by our shareholders at the Annual General Meeting in May 2014, was achieved through the issuance and subsequent cancellation of $3.0 billion of a newly-created class of shares (the “Capital Reorganization Shares”).
The Capital Reorganization Shares had no substantive economic or voting rights and were issued to a subsidiary of the Company on June 17, 2014 for the benefit of existing shareholders solely for the purpose of the Capital Reorganization transaction. Upon cancellation of the shares on June 18, 2014, $3.0 billion of the shareholders' equity of Ensco plc that was previously deemed non-distributable under UK law, can now be included in the determination of eligible distributable reserves.
The Capital Reorganization did not involve any distribution or repayment of capital, nor did it have an impact on the underlying net assets of the Company. There was no net impact on our shareholders’ equity for any period as a result of the Capital Reorganization.

Effects of Climate Change and Climate Change Regulation
 
Greenhouse gas ("GHG") emissions have increasingly become the subject of international, national, regional, state and local attention. During 2009, the United States Environmental Protection Agency (the "EPA") officially published its findings that emissions of carbon dioxide, methane and other GHGs present an endangerment to human health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth's atmosphere and other climatic changes. These EPA findings allowed the agency to proceed with the adoption and implementation of regulations to restrict GHG emissions under existing provisions of the Clean Air Act that establish Prevention of Significant Deterioration ("PSD") construction and Title V operating permit reviews for certain large stationary sources that are potential major sources of GHG emissions. The EPA set the current regulatory GHG emissions thresholds in its "Tailoring Rule" and has indicated that it may revise this Rule's thresholds downward in a subsequent rule, which would likely subject additional stationary sources to GHG permitting requirements. Facilities required to obtain PSD permits for their GHG emissions also will be required to meet "best available control technology" standards to be established by the states or, in some cases, the EPA, on a case-by-case basis. The EPA has also adopted rules requiring annual monitoring and reporting of GHG emissions from specified sources in the United States, including, among others, certain onshore and offshore oil and natural gas production facilities.

In recent years, cap and trade initiatives to limit GHG emissions have been introduced in the European Union. Similarly, a number of bills related to climate change have been introduced in the U.S. Congress. If these or similar bills were to be adopted, such legislation could adversely impact many industries. However, it appears unlikely that comprehensive federal climate legislation will be passed by the U.S. Congress in the foreseeable future. In the absence of federal legislation, almost half of the states have begun to address GHG emissions, primarily through the development or planned development of emission inventories or regional GHG cap and trade programs. Future regulation of GHG emissions could occur pursuant to future treaty obligations, statutory or regulatory changes or new climate change legislation in the jurisdictions in which we operate. If the U.S. Congress undertakes comprehensive tax reform in the coming year, it is possible that such reform may include a carbon tax, which could impose additional direct costs on operations and reduce demand for refined products. Depending on the particular program, we, or our customers, could be required to control GHG emissions or to purchase and surrender allowances for GHG emissions resulting from our operations. It is uncertain whether any of these initiatives will be implemented. If such initiatives are implemented, we do not believe that such initiatives would have a direct, material adverse effect on our financial condition, operating results or cash flows in a manner different than our competitors.

Restrictions on GHG emissions or other related legislative or regulatory enactments could have an indirect effect in those industries that use significant amounts of petroleum products, which could potentially result in a reduction in demand for petroleum products and, consequently, our offshore contract drilling services. We are currently unable to predict the manner or extent of any such effect. Furthermore, one of the long-term physical effects of climate change may be an increase in the severity and frequency of adverse weather conditions, such as hurricanes, which may increase our insurance costs or risk retention, limit insurance availability or reduce the areas in which, or the number of days during which, our customers would contract for our drilling rigs in general and in the Gulf of Mexico in particular. We are currently unable to predict the manner or extent of any such effect.

MARKET RISK
 
We use derivatives to reduce our exposure to foreign currency exchange rate risk. Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues and expenses are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. We maintain a foreign currency exchange rate risk management strategy that utilizes derivatives to reduce our exposure to unanticipated fluctuations in earnings and cash flows caused by changes in foreign currency exchange rates.  

57

We utilize cash flow hedges to hedge forecasted foreign currency denominated transactions, primarily to reduce our exposure to foreign currency exchange rate risk on future expected contract drilling expenses and capital expenditures denominated in various foreign currencies. We predominantly structure our drilling contracts in U.S. dollars, which significantly reduces the portion of our cash flows and assets denominated in foreign currencies. As of September 30, 2014 , we had cash flow hedges outstanding to exchange an aggregate $391.2 million for various foreign currencies.
We have net assets and liabilities denominated in numerous foreign currencies and use various strategies to manage our exposure to changes in foreign currency exchange rates. We occasionally enter into derivatives that hedge the fair value of recognized foreign currency denominated assets or liabilities, thereby reducing exposure to earnings fluctuations caused by changes in foreign currency exchange rates. We do not designate such derivatives as hedging instruments. In these situations, a natural hedging relationship generally exists whereby changes in the fair value of the derivatives offset changes in the fair value of the underlying hedged items. As of September 30, 2014 , we held derivatives not designated as hedging instruments to exchange an aggregate $211.2 million for various foreign currencies.
If we were to incur a hypothetical 10% adverse change in foreign currency exchange rates, net unrealized losses associated with our foreign currency denominated assets and liabilities as of September 30, 2014 would approximate $27.6 million . Approximately $18.0 million of these unrealized losses would be offset by corresponding gains on the derivatives utilized to offset changes in the fair value of net assets and liabilities denominated in foreign currencies.
We utilize derivatives and undertake foreign currency exchange rate hedging activities in accordance with our established policies for the management of market risk. We mitigate our credit risk relating to counterparties of our derivatives through a variety of techniques, including transacting with multiple, high-quality financial institutions, thereby limiting our exposure to individual counterparties and by entering into ISDA Master Agreements, which include provisions for a legally enforceable master netting agreement, with almost all of our derivative counterparties. The terms of the ISDA agreements may also include credit support requirements, cross default provisions, termination events, or set-off provisions. Legally enforceable master netting agreements reduce credit risk by providing protection in bankruptcy in certain circumstances and generally permitting the closeout and netting of transactions with the same counterparty upon the occurrence of certain events.

We do not enter into derivatives for trading or other speculative purposes. We believe that our use of derivatives and related hedging activities reduces our exposure to foreign currency exchange rate risk and does not expose us to material credit risk or any other material market risk. All of our derivatives mature during the next 18 months . See Note 3 to our condensed consolidated financial statements for additional information on our derivative instruments.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires our management to make estimates, judgments and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Our significant accounting policies are included in Note 1 to our audited consolidated financial statements for the year ended December 31, 2013 included in our annual report on Form 10-K filed with the SEC on February 26, 2014 , as updated on September 22, 2014. These policies, along with our underlying judgments and assumptions made in their application, have a significant impact on our consolidated financial statements.

58

We identify our critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and operating results and that require the most difficult, subjective and/or complex judgments by management regarding estimates in matters that are inherently uncertain. Our critical accounting policies are those related to property and equipment, impairment of long-lived assets and goodwill and income taxes. For a discussion of the critical accounting policies and estimates that we use in the preparation of our condensed consolidated financial statements, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates" in Part II of our annual report on Form 10-K for the year ended December 31, 2013 . Other than set forth below, there have been no material changes from the critical accounting policies previously disclosed in our annual report on Form 10-K for the year ended December 31, 2013, as updated in our subsequent quarterly reports.

Impairment of Long-Lived Assets and Goodwill

During the second quarter of 2014, demand for floaters deteriorated as a result of continued reduction in capital spending by operators in addition to recently announced delays in operators’ drilling programs. The reduction in demand, combined with the increasing supply from newbuild floater deliveries, led to a very competitive market. In general, contracting activity for floaters declined significantly, and new day rate fixtures were substantially lower than rates realized during the first quarter of 2014 and fourth quarter of 2013. More specifically, drilling contractors have been unable to contract older, less capable rigs as operators are now targeting premium, high-specification rigs at lower day rates. The significant supply and demand imbalance will continue to be adversely impacted by future newbuild deliveries, program delays and lower capital spending by operators. As a result, day rates and utilization will remain under pressure, especially for older, less capable floaters. In response to the adverse change in the current and anticipated floaters business climate, management evaluated our older, less capable floaters and committed to a plan to sell five rigs. These rigs were written down to fair value, less costs to sell, as of May 31, 2014 and classified as "held for sale" on our September 30, 2014 condensed consolidated balance sheet.

We measured the fair value of the "held for sale" rigs by applying a market approach, which was based on unobservable third-party estimated prices that would be received in exchange for the assets in an orderly transaction between market participants. We recorded a pre-tax, non-cash loss on impairment totaling $546.4 million during the nine-month period ended September 30, 2014 . The impairment charge was included in (loss) income from discontinued operations, net in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . See "Note 9 - Discontinued Operations" for additional information on our "held for sale" rigs.

On a quarterly basis, we evaluate the carrying value of our property and equipment to identify events or changes in circumstances ("triggering events") that indicate the carrying value may not be recoverable. As a result of the adverse change in the floater business climate observed during the second quarter of 2014, management's commitment to a plan to sell five floaters during the second quarter of 2014 and the impairment charge incurred on the "held for sale" floaters, management concluded that a triggering event had occurred during the second quarter of 2014 and performed an asset impairment analysis on our remaining older, less capable floaters.

Based on the analysis performed as of May 31, 2014 , we recorded an additional non-cash loss on impairment with respect to four other floaters totaling $991.5 million . The impairment charge was included in loss on impairment in our condensed consolidated statement of operations for the nine-month period ended September 30, 2014 . We measured the fair value of these rigs by applying an income approach, using projected discounted cash flows. These valuations were based on unobservable inputs that require significant judgments for which there is limited information, including assumptions regarding future day rates, utilization, operating costs and capital requirements.

Our business consists of three operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups and (3) Other, which consists of management services on rigs owned by third-parties. Our two reportable segments, Floaters and Jackups, provide one service, contract drilling.

59

We test goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists.  Management concluded that the aforementioned adverse change in the current and anticipated floater business climate, the commitment to a plan to sell five floaters and the impairment charge on the "held for sale" floaters triggered an interim impairment test to evaluate the Floaters reporting unit goodwill balance of $3.1 billion as of May 31, 2014 .

Based on the valuation performed as of May 31, 2014 , the Floaters reporting unit estimated fair value exceeded the carrying value (adjusted for the long-lived impairments noted above) by approximately 7% ; therefore, we concluded that the goodwill balance was not impaired.  We estimated the fair value of the Floaters reporting unit using a blended income and market approach.

The income approach was based on a discounted cash flow model, which utilized present values of cash flows to estimate fair value. The future cash flows were projected based on our estimates of future day rates, utilization, operating costs, capital requirements, growth rates and terminal values for our rigs. Forecasted day rates and utilization take into account current market conditions and our anticipated business outlook, both of which have been impacted by the recent adverse change in the floater business environment. The day rates reflected contracted rates during the respective contracted periods and management's estimate of market day rates in uncontracted periods. The forecasted market day rates were held constant in the near-term and were forecasted to grow in the longer-term and terminal period.

Operating costs were forecasted using our historical average operating costs and were adjusted for an estimated inflation factor. Capital requirements in the discounted cash flow model were based on management's estimates of future capital costs, taking into consideration our historical trends. The estimated capital requirements include cash outflows for new rig construction, rig enhancements and minor upgrades and improvements.

A terminal period was used to reflect our estimate of stable, perpetual growth. The terminal period reflects a terminal growth rate of 3.5% , which includes an estimated inflation factor. The future cash flows were discounted using a market-participant risk-adjusted weighted average cost of capital ("WACC") of 10.5% .

These assumptions were derived from unobservable inputs and reflect management's judgments and assumptions. A decline in the Floaters reporting unit cash flow projections or changes in other key assumptions may result in a goodwill impairment charge in the future. Specifically, keeping all other variables constant, a 50 basis point increase in the WACC applied would reduce the estimated fair value of our Floaters reporting unit below its carrying value. In addition, keeping all other variables constant, a 1.5% reduction in the terminal growth rate would reduce the estimated fair value of our Floaters reporting unit below its carrying value. Also, keeping all other variables constant, a 5.0% reduction in our forecasted market day rates would reduce the estimated fair value of our Floaters reporting unit below its carrying value.

The market approach was based upon the application of price-to-earnings multiples to management's estimates of future earnings adjusted for a control premium. The price-to-earnings multiples used in the market valuation ranged from 7.5 x to 8.5 x and were based on competitor market multiples. The fair value determined under the market approach is sensitive to these multiples, and a decline in any of the multiples could reduce the estimated fair value of our Floaters reporting unit below its carrying value. Management's earnings estimates were derived from unobservable inputs that require significant estimates, judgments and assumptions as described in the income approach.

The estimated fair value of the Floaters reporting unit determined under the income approach was consistent with the estimated fair value determined under the market approach. For purposes of the goodwill impairment test, we calculated the Floaters reporting unit estimated fair value as the average of the values calculated under the income approach and the market approach.

60

We evaluated the estimated fair value of our reporting units compared to our market capitalization as of May 31, 2014 . To perform this assessment, we used a market approach to estimate the fair value of the Jackups reporting unit. The aggregate fair values of our reporting units exceeded our market capitalization, and we believe the resulting implied control premium was reasonable based on recent market transactions within our industry or other relevant benchmark data.

Our stock price declined significantly during September and October 2014 reaching a twelve-month low of $35.96 on October 10th. Our stock price traded between $47.85 and $57.45 during the eight-month period ended August 2014. The average stock price for the three-month period ended September 30, 2014 was $49.01 , including average stock prices of $52.79 and $48.78 in July and August, respectively.

A sustained decline in our stock price is one of several qualitative factors we consider each quarter when evaluating whether events or changes in circumstances indicate that a potential goodwill impairment exists. We concluded that the decline in stock price observed in September and October did not represent a sustained decline and that no triggering events occurred during the third quarter requiring an interim goodwill impairment test as of September 30, 2014.

If our Floater operating performance or Floater anticipated business outlook deteriorates and/or our stock trades at current levels for a sustained period, our Floaters reporting unit estimated fair value could decline below its carrying value, resulting in a goodwill impairment.

Factors that could have a negative impact on the fair value of the Floaters reporting unit include, but are not limited to:

•	decreases in estimated market day rates and utilization due to greater-than-expected market pressures, downtime and other risks associated with offshore rig operations;	

•	sustained declines in our stock price;	

•	decreases in revenue due to our inability to attract and retain skilled personnel;	

•	changes in worldwide rig supply and demand, competition or technology, including changes as a result of delivery of newbuild drilling rigs;	

•	changes in future levels of drilling activity and expenditures, whether as a result of global capital markets and liquidity, prices of oil and natural gas or otherwise, which may cause us to idle or stack additional rigs;	

•	possible cancellation or suspension of drilling contracts as a result of mechanical difficulties, performance or other reasons;	

•	delays in actual contract commencement dates;	

•	the outcome of litigation, legal proceedings, investigations or other claims or contract disputes resulting in significant cash outflows;	

•	governmental, regulatory, legislative and permitting requirements affecting drilling operations, including limitations on drilling locations (such as the Gulf of Mexico during hurricane season);	

•	increases in the market-participant risk-adjusted WACC;	

•	declines in anticipated growth rates.	

61

Adverse changes in one or more of these factors could reduce the estimated fair value of our Floaters reporting unit below its carrying value in future periods.

New Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("Update 2014-08"). The new guidance changes the criteria for reporting discontinued operations and enhances disclosure requirements. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Update 2014-08 is effective for annual and interim periods for fiscal years beginning on or after December 15, 2014 and early adoption is permitted for disposals that have not been reported in financial statements previously issued or available for issuance. The adoption of ASU 2014-08 is expected to reduce the number of components reported as discontinued operations prospectively in our consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) ("Update 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective on January 1, 2017. Early application is not permitted. We are currently evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures.

In June 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-12, Compensation- Stock Compensation (Topic 718): Accounting for Share Payments When the Terms of an Award Provide That a Performance Target Could be Achieved After the Requisite Service Period ("Update 2014-12"). The new guidance clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Update 2014-12 is effective for annual and interim periods for fiscal years beginning after December 15, 2015 and early adoption is permitted. We will adopt the accounting standard on a prospective basis effective January 1, 2016. We do not expect the adoption to have a material effect on our consolidated financial statements.

In August 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“Update 2014-15”). The new guidance clarifies management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Update 2014-15 is effective for annual periods ending after December 15, 2016 and for annual periods and interim periods thereafter. Early adoption is permitted. We will adopt the accounting standard on January 1, 2016. We do not expect the adoption to have a material effect on our consolidated financial statements.

PART II - OTHER INFORMATION

Item 1.    Legal Proceedings
 
Pride FCPA Investigation

During 2010, Pride and its subsidiaries resolved their previously disclosed investigations into potential violations of the FCPA with the DOJ and SEC. The settlement with the DOJ included a deferred prosecution agreement (the "DPA") between Pride and the DOJ and a guilty plea by Pride Forasol, S.A.S., one of Pride’s subsidiaries, to FCPA-related charges. During 2012, the DOJ moved to (i) dismiss the charges against Pride and end the DPA one year prior to its scheduled expiration; and (ii) terminate the unsupervised probation of Pride Forasol, S.A.S. The Court granted the motions.

     Pride has received preliminary inquiries from governmental authorities of certain countries referenced in its settlements with the DOJ and SEC. We could face additional fines, sanctions and other penalties from authorities in these and other relevant jurisdictions, including prohibition of our participating in or curtailment of business operations in those jurisdictions and the seizure of rigs or other assets. At this early stage of such inquiries, we are unable to determine what, if any, legal liability may result. Our customers in those jurisdictions could seek to impose penalties or take other actions adverse to our business. We could also face other third-party claims by directors, officers, employees, affiliates, advisors, attorneys, agents, stockholders, debt holders, or other interest holders or constituents of our Company. In addition, disclosure of the subject matter of the investigations and settlements could adversely affect our reputation and our ability to obtain new business or retain existing business from our current clients and potential clients, to attract and retain employees and to access the capital markets.

We cannot currently predict what, if any, actions may be taken by any other applicable government or other authorities or our customers or other third parties or the effect any such actions may have on our financial position, operating results or cash flows.

Asbestos Litigation
 
We and certain subsidiaries have been named as defendants, along with numerous third-party companies as co-defendants, in multi-party lawsuits filed in Illinois, Mississippi, Texas, Louisiana and the UK by approximately 125 plaintiffs. The lawsuits seek an unspecified amount of monetary damages on behalf of individuals alleging personal injury or death, primarily under the Jones Act, purportedly resulting from exposure to asbestos on drilling rigs and associated facilities during the 1960s through the 1980s.

During 2013, we reached an agreement in principle with 58 of the plaintiffs to settle lawsuits filed in Mississippi for a nominal amount. While we believe the settlement will be approved by the Court, there can be no assurances as to the ultimate outcome.

We intend to vigorously defend against the remaining claims and have filed responsive pleadings preserving all defenses and challenges to jurisdiction and venue. However, discovery is still ongoing and, therefore, available information regarding the nature of all pending claims is limited. At present, we cannot reasonably determine how many of the claimants may have valid claims under the Jones Act or estimate a range of potential liability exposure, if any.
 
In addition to the pending cases in Mississippi and Louisiana, we have other asbestos or lung injury claims pending against us in litigation in other jurisdictions. Although we do not expect final disposition of these asbestos or lung injury lawsuits to have a material adverse effect upon our financial position, operating results or cash flows, there can be no assurances as to the ultimate outcome of the lawsuits.

Environmental Matters

We are currently subject to pending notices of assessment relating to spills of drilling fluids, oil, chemicals, grease or fuel from drilling rigs operating offshore Brazil from 2008 through 2014, pursuant to which the governmental authorities have assessed, or are anticipated to assess, fines in an aggregate amount of approximately $250,000 . We have contested these notices and appealed certain adverse decisions and are awaiting decisions in these cases. Although we do not expect final disposition of these assessments to have a material adverse effect on our financial position, operating results or cash flows, there can be no assurance as to the ultimate outcome of these assessments. A $250,000 liability related to these matters was included in accrued liabilities and other on our condensed consolidated balance sheet as of September 30, 2014 .

We currently are subject to a pending administrative proceeding initiated during 2009 by a Spanish government authority seeking payment in an aggregate amount of approximately $4.0 million for an alleged environmental spill originating from ENSCO 5006 while it was operating offshore Spain. Our customer has posted guarantees with the Spanish government to cover potential penalties. Additionally, we expect to be indemnified for any payments resulting from this incident by our customer under the terms of the drilling contract. A criminal investigation of the incident was initiated during 2010 by a prosecutor in Tarragona, Spain, and the administrative proceedings have been suspended pending the outcome of this investigation. We do not know at this time what, if any, involvement we may have in this investigation.
 
We intend to vigorously defend ourselves in the administrative proceeding and any criminal investigation. At this time, we are unable to predict the outcome of these matters or estimate the extent to which we may be exposed to any resulting liability. Although we do not expect final disposition of this matter to have a material adverse effect on our financial position, operating results or cash flows, there can be no assurance as to the ultimate outcome of the proceedings.

We received a notice of assessment from the Bureau of Safety and Environmental Enforcement ("BSEE") in June 2014 relating to an unintended disconnect on ENSCO 8500, pursuant to which BSEE assessed a fine in the amount of $330,000. The elements of the fine included a small discharge of pollutants into the Gulf of Mexico and other elements that are indirectly related as the reason the discharge occurred. We accrued a $330,000 liability for these fines as of June 30, 2014. Following an August meeting with BSEE representatives to discuss and review the penalty notice and underlying facts, BSEE reduced the civil penalty assessment from $330,000 to $70,000. The $330,000 accrued liability related to this matter was reduced to $70,000 and included in accrued liabilities and other on our condensed consolidated balance sheet as of September 30, 2014 .

Other Matters

In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results or cash flows.

As of September 30, 2014 , no shares have been repurchased under the share repurchase program. The program terminates in May 2018.

(c)    The following terms have the meanings given to them in this Section 3.01(c):

“ Comparable Treasury Price ” means, with respect to any Redemption Date, (i) the average of two Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Company is given fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if only one Reference Treasury Dealer Quotation is received, such quotation.

(a)    The Company may redeem the Notes, in whole but not in part, at its option upon giving not less than 30 nor more than 60 days’ prior written notice to the Trustee and the Holders of the Notes, at a redemption price equal to 100% of the aggregate principal amount thereof, together with accrued and unpaid interest, if any, to the Redemption Date and all Additional Amounts, if any, which otherwise would be payable, if on the next date on which any amount would be payable in respect of the Notes, the Company would be required to pay Additional Amounts, and the Company cannot avoid any such payment obligation by taking reasonable measures available to it, as a result of:

(i)    any amendment to, or change in, the laws, Tax treaties or any regulations or rulings promulgated thereunder of a relevant Tax Jurisdiction which is announced and becomes effective after September 24, 2014 (or, if the applicable Tax Jurisdiction became a Tax Jurisdiction on a date after September 24, 2014, such later date); or

(ii)    any amendment to, or change in, an official interpretation or application regarding such laws, Tax treaties, regulations or rulings, including by virtue of a holding, judgment or order by a court of competent jurisdiction which is announced and becomes effective after September 24, 2014 (or, if the applicable Tax Jurisdiction became a Tax Jurisdiction on a date after September 24, 2014, such later date).

If any deduction or withholding for, or on account of, any Taxes imposed or levied by or on behalf of (1) any jurisdiction in which the Company is organized, resident or doing business for Tax purposes or any department or political subdivision thereof or therein or (2) any jurisdiction from or through which payment is made by the Company or the Paying Agent or any department or political subdivision thereof or therein (each, a “ Tax Jurisdiction ”) will at any time be required to be made from any payments made under or with respect to the Notes, including payments of principal, redemption price, interest or premium, the Company will pay such additional amounts (the “ Additional Amounts ”) as may be necessary in order that the net amounts received in respect of such payments by each Holder of the Notes after such withholding or deduction (including any such deduction or withholding in respect of Additional Amounts) will equal the respective amounts which would have been received in respect of such payments in the absence of such withholding or deduction; provided , however , that no Additional Amounts will be payable with respect to:

(i)    any Taxes, to the extent such Taxes would not have been imposed but for the existence of any present or former connection between the Holder or the beneficial owner of the Notes and the relevant Tax Jurisdiction (other than any connection arising solely from the acquisition, ownership, holding or disposition of the Notes, the enforcement of rights under the Notes and/or the receipt of any payments in respect of the Notes);

(ii)    any Taxes, to the extent such Taxes would not have been imposed but for the failure of the Holder or the beneficial owner of the Notes to comply with any certification, identification, information, documentation, or other reporting requirements, including an application for relief under an applicable double Tax treaty, whether required by statute, treaty, regulation or administrative practice of a Tax Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Tax Jurisdiction (including, without limitation, a certification that the Holder or beneficial owner of the Notes is not resident in the Tax Jurisdiction or is a resident of an applicable Tax treaty jurisdiction), but in each case, only to the extent the Holder or the beneficial owner of the Notes is legally eligible to provide such certification or documentation; provided, however, that in the event that any such requirements are imposed as a result of an amendment to, or change in, any laws, Tax treaties, regulations or rulings (or any official administrative or judicial interpretation thereof) after the Issue Date, this paragraph (2) will apply only if the Company notifies the Trustee, at least 30 days before any such withholding or deduction would be payable, that Holders or beneficial owners of the Notes must comply with such certification, identification, information, documentation or other reporting requirements;

(iii)    any Taxes, to the extent such Taxes were imposed as a result of the presentation of a Note for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder of such Note (except to the extent that such Holder would have been entitled to Additional Amounts had the Note been presented on the last day of such 30 day period);

(iv)    any estate, inheritance, gift, transfer, personal property or similar Tax;

(v)    any Taxes payable otherwise than by deduction or withholding from payments made under or with respect to the Notes;

(vi)    any Taxes required to be withheld pursuant to the EC Council Directive on the Taxation of Savings Income in the Form of Interest Payments (Directive 2003/48/EC) (as amended by EC Counsel Directive 2014/48/EU on March 24, 2014) or any law implementing or complying with, or introduced in order to conform to, such Directive or any agreement between the European Union and any non-EU jurisdiction providing for equivalent measures;

(vii)    any Taxes required to be withheld in respect of a payment of interest in respect of Notes presented for payment by or on behalf of a Holder of the Notes who would be able to avoid such withholding or deduction by presenting the relevant Note to another Paying Agent in a member state of the European Union; or

(viii)    any combination of the above items.

The Company also will not pay any Additional Amounts to any Holder of the Notes who is a fiduciary or partnership or other than the sole beneficial owner of the Notes to the extent that the obligation to pay Additional Amounts would be reduced or eliminated by transferring the Notes in question to the sole beneficial owner, but only if there is no material commercial or legal impediment to, or material cost associated with, transferring the Notes to the sole beneficial owner.
In addition to the foregoing, the Company will also pay and indemnify the Holder of the Notes for any present or future stamp, issue, registration, transfer, court or documentary taxes, or any other excise or property taxes, charges or similar levies (including penalties, interest, additions to Tax and other liabilities related thereto) which are levied by any Tax Jurisdiction on the execution, delivery, issuance, or registration of any of the Notes, the Indenture or any other document or instrument referred to therein, or the receipt of any payments with respect to, or enforcement of, the Notes.
(b)    If the Company becomes aware that it will be obligated to pay Additional Amounts with respect to any payment under or with respect to the Notes, the Company will deliver to the Trustee on a date which is at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 30th day prior to that payment date, in which case the Company shall notify the Trustee promptly thereafter) notice stating the fact that Additional Amounts will be payable and the amount estimated to be so payable. The notice must also set forth any other information reasonably necessary to enable the Paying Agent to pay Additional Amounts to Holders of the Notes on the relevant payment date. The Company will provide the Trustee with documentation reasonably satisfactory to the Trustee evidencing the payment of Additional Amounts.

(c)    The Company will timely make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the relevant Tax authority in accordance with applicable law. The Company will furnish to the Trustee (or to a Holder of the Notes upon request), within a reasonable time after the date the payment of any Taxes so deducted or withheld is made, certified copies of Tax receipts evidencing payment by the Company, or if receipts are not reasonably available, other evidence of payment reasonably satisfactory to the Trustee.

(d)    Whenever in the Indenture or this Supplemental Indenture there is mentioned, in any context, the payment of amounts based upon the principal amount of the Notes or of principal, interest or of any other amount payable under, or with respect to, any of the Notes such mention shall be deemed to include the payment to the Paying Agent of Additional Amounts, if applicable.

(e)    The obligations under this Section 4.01 will survive any termination, defeasance or discharge of the Indenture and will apply, mutatis mutandis , to any jurisdiction in which any successor Person to the Company is organized, resident or doing business for Tax purposes or any jurisdiction from or through which such Person or its

Paying Agent makes any payment on the Notes and, in each case, any department or political subdivision thereof or therein.

The foregoing restrictions will not, however, apply to Indebtedness secured by Permitted Liens.

(b)    Notwithstanding the foregoing, the Company and its Subsidiaries may, without securing the Notes, incur, issue or assume Indebtedness that would otherwise be subject to the foregoing restrictions in an aggregate principal amount that, together with all other such Indebtedness of the Company and its Subsidiaries that would otherwise be subject to the foregoing restrictions (not including Indebtedness permitted to be secured under the definition of Permitted Liens) and the aggregate amount of Attributable Indebtedness deemed outstanding with respect to Sale/Leaseback Transactions (other than Sale/Leaseback Transactions in connection with which the Company has voluntarily retired any of the Notes, any Pari Passu Indebtedness or any Funded Indebtedness pursuant to Section 5.02(b)(iii)(x)) does not at any one time exceed 15% of Consolidated Net Tangible Assets.

(c)    For purposes of this Section 5.01, if at the time any Indebtedness is incurred, issued or assumed, such Indebtedness is unsecured but is later secured by a Lien, such Indebtedness shall be deemed to be incurred at the time that such Indebtedness is so secured by a Lien.

Section 5.02. Limitation on Sale/Leaseback Transactions

(a)    So long as the Notes are outstanding, the Company will not, and the Company will not permit any Subsidiary to, sell or transfer (other than to the Company or a Wholly Owned Subsidiary) any Principal Property, whether owned at the date of the Indenture or thereafter acquired, which has been in full operation for more than 120 days prior to such sale or transfer, with the intention of entering into a lease of such Principal Property (except for a lease for a term, including any renewal thereof, of not more than three years), if after giving effect thereto the Attributable Indebtedness in respect of all such sale and leaseback transactions involving Principal Properties shall be in excess of 15% of Consolidated Net Tangible Assets.

(b)    Notwithstanding the foregoing, the Company or any Subsidiary may sell any Principal Property and lease it back if the net proceeds of such sale are at least equal to the fair value of such property as determined by the Board of Directors and:

(i)    the Company or such Subsidiary would be entitled to incur Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction secured by a Lien on the property subject to such Sale/Leaseback Transaction pursuant to Section 5.01 without equally and ratably securing the Notes pursuant to such Section;

(ii)    after the Issue Date and within a period commencing nine months prior to the consummation of such Sale/Leaseback Transaction and ending nine months after the consummation thereof, the Company or such Subsidiary shall have expended for property used or to be used in the ordinary course of its business and that of its Subsidiaries an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction and the Company shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause (iii) below or as otherwise permitted); or

(iii)    the Company, during the nine-month period after the effective date of such Sale/Leaseback Transaction, shall have applied to either (x) the voluntary defeasance or retirement of any Notes, any Pari Passu Indebtedness or any Funded Indebtedness or (y) the acquisition of one or more Principal Properties at fair value, an amount equal to the greater of the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback Transaction and the fair value, as determined by the Board of Directors, of such property as of the time of entering into such Sale/Leaseback Transaction (in either case adjusted to reflect the remaining term of the lease and any amount expended by the Company as set forth in the preceding clause (ii)), less an amount equal to the sum of the principal amount of Notes, Pari Passu Indebtedness and Funded Indebtedness voluntarily defeased or retired by the Company plus any amount expended to acquire any Principal Properties at fair value, within such nine month period and not designated as a credit against any other Sale/Leaseback Transaction entered into by the Company or any of its Subsidiaries during such period.
