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, such as hurricanes in the Gulf of Mexico or associated removal of wreckage or debris;	

•	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, 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 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part I and "Item 1A. Risk Factors" in Part II of this report and "Item 1A. Risk Factors" in Part I and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II of our annual report on Form 10-K for the year ended December 31, 2013 , which is available on the SEC's website at www.sec.gov. Each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise any forward looking statements, except as required by law .

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 accompanying condensed consolidated balance sheet of Ensco plc and subsidiaries (the Company) as of March 31, 2014 , and the related condensed consolidated statements of income, comprehensive income, and cash flows for the three-month periods ended March 31, 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 review, 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 , 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 quarter s ended March 31, 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 quarter ended March 31, 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 .

Note 2 - Fair Value Measurements
 
The following fair value hierarchy table categorizes information regarding our net financial assets measured at fair value on a recurring basis (in millions):

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.
 
Other Financial Instruments
 
The carrying values and estimated fair values of our long-term debt instruments were as follows (in millions):

																
 	March 31,
2014	 	December 31,
2013	
 	Carrying Value  	 	Estimated Fair Value  	 	Carrying Value  	 	Estimated Fair Value  	
4.70% Senior notes due 2021	$	1,477.9		 	$	1,614.8		 	$	1,477.2		 	$	1,596.9		
6.875% Senior notes due 2020	1,020.7		 	1,076.6		 	1,024.8		 	1,086.7		
3.25% Senior notes due 2016	996.9		 	1,043.3		 	996.5		 	1,045.8

7.875% Senior notes due 2040	382.2		 	427.3		 	382.6		 	410.5		
7.20% Debentures due 2027	149.1		 	182.4		 	149.1		 	178.6		
4.33% MARAD bonds, including current maturities, due 2016	71.2		 	71.6		 	78.9		 	79.7		
4.65% MARAD bonds, including current maturities, due 2020	31.5		 	34.9		 	31.5		 	35.2		
6.36% MARAD bonds, including current maturities, due 2015	25.3		 	26.7		 	25.3		 	27.1		
Total	$	4,751.2		 	$	5,110.1		 	$	4,766.4		 	$	5,096.3		

The estimated fair values of our senior notes and debentures were determined using quoted market prices. The estimated fair values of our Maritime Administration ("MARAD") bonds were determined using an income approach valuation model. The estimated fair values of our cash and cash equivalents, short-term investments, receivables, trade payables and other liabilities approximated their carrying values as of March 31, 2014 and December 31, 2013 .

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

9

derivative and whether it qualifies for hedge accounting.  Net assets of $8.8 million and $1.8 million associated with our foreign currency forward contracts were included on our condensed consolidated balance sheets as of March 31, 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.

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 March 31, 2014 , we had cash flow hedges outstanding to exchange an aggregate $392.2 million for various foreign currencies, including $188.3 million for British pounds, $118.1 million for Brazilian reais, $34.8 million for Singapore dollars, $22.6 million for euros, $19.4 million for Australian dollars and $9.0 million for other currencies.

Gains and losses, net of tax, on derivatives designated as cash flow hedges included in our condensed consolidated statements of income and comprehensive income for the quarter s ended March 31, 2014 and 2013 were as follows (in millions):

	
																								
 	Gain (Loss) Recognized in Other Comprehensive Income ("OCI") (Effective Portion)  	 	(Loss) Gain Reclassified from Accumulated Other Comprehensive Income ("AOCI") into Income (Effective Portion) (1)	 	Gain Recognized in Income on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing) (2)

(1)	Changes in the fair value of cash flow hedges are recorded in AOCI.  Amounts recorded in AOCI associated with cash flow hedges are subsequently reclassified into contract drilling, depreciation or interest expense as earnings are affected by the underlying hedged forecasted transaction.	

(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 income.	

(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 income.	

(4)  	During the quarter ended March 31, 2014 , $600,000 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 income. During the quarter ended March 31, 2013 , $900,000 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 income.	

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 March 31, 2014 , we held derivatives not designated as hedging instruments to exchange an aggregate $223.0 million for various foreign currencies, including $109.7 million for euros, $30.6 million for British pounds, $25.7 million for Swiss francs,  $19.1 million for Indonesian rupiah, $15.2 million for Australian dollars and  $22.7 million for other currencies.
     
Net losses of $600,000 and $4.4 million associated with our derivatives not designated as hedging instruments were included in other, net in our condensed consolidated statements of income for the quarter s ended March 31, 2014 and 2013 , respectively.

As of March 31, 2014 , the estimated amount of net  gains associated with derivative instruments, net of tax, that would be reclassified into earnings during the next twelve months totaled $4.3 million .

Note 4 - Noncontrolling Interests

Third parties hold a noncontrolling ownership interest in certain of our non-U.S. subsidiaries. Noncontrolling interests are classified as equity on our condensed consolidated balance sheets, and net income attributable to noncontrolling interests is presented separately in our condensed consolidated statements of income.
    
Income from continuing operations attributable to Ensco for the quarter s ended March 31, 2014 and 2013 was as follows (in millions):

								
 	2014	 	2013	
Income from continuing operations	$	296.7		 	$	320.8		
Income from continuing operations attributable to noncontrolling interests	(4.2	)	 	(2.8	)	
Income from continuing operations attributable to Ensco	$	292.5		 	$	318.0		

Loss from discontinued operations, net, for the quarter ended March 31, 2013 was attributable to Ensco.

Note 5 - Earnings Per Share
 
We compute basic and diluted earnings per share ("EPS") in accordance with the two-class method. Net income attributable to Ensco used in our computations of basic and diluted EPS is adjusted to exclude net income allocated to non-vested shares granted to our employees and non-employee directors. Weighted-average shares outstanding used in our computation of diluted EPS is calculated using the treasury stock method and excludes non-vested shares.
    
The following table is a reconciliation of net income attributable to Ensco shares used in our basic and diluted EPS computations for the quarter s ended March 31, 2014 and 2013 (in millions):

								
 	2014	 	2013	
Net income attributable to Ensco	$	292.5		 	$	317.1		
Net income allocated to non-vested share awards	(3.0	)	 	(3.3	)	
Net income attributable to Ensco shares	$	289.5		 	$	313.8		
 
The following table is a reconciliation of the weighted-average shares used in our basic and diluted EPS computations for the quarter s ended March 31, 2014 and 2013 (in millions):

						
 	2014	 	2013	
Weighted-average shares - basic	231.3		 	230.3		
Potentially dilutive shares	.1		 	.3		
Weighted-average shares - diluted	231.4		 	230.6		
 
Antidilutive share options totaling 400,000 and 100,000 were excluded from the computation of diluted EPS for the quarter s ended March 31, 2014 and 2013 , respectively.

Note 6 - Discontinued Operations
    
During the first quarter of 2013, we sold jackup rig Pride Pennsylvania for net proceeds of $15.5 million . The rig was classified as held for sale and included in discontinued operations during 2012 in connection with the sale of multiple rigs in our fleet. The proceeds from the sale were included in investing activities of discontinued operations in our condensed consolidated statement of cash flows for the quarter ended March 31, 2013. We recognized a loss of $1.1 million in connection with the disposal, which was included in loss from discontinued operations, net, in our condensed consolidated statement of income for the quarter ended March 31, 2013. Pride Pennsylvania operating results were included in loss from discontinued operations, net in our condensed consolidated statement of income for the quarter ended March 31, 2013.

The following table summarizes loss from discontinued operations, net, for the quarter ended March 31, 2013  (in millions):

Note 7 - Income Taxes
 
Our consolidated effective income tax rate for the quarter ended March 31, 2014 was 16.5% as compared to 13.9% in the prior year quarter. Excluding the impact of discrete tax items, our consolidated effective income tax rate for the quarter s ended March 31, 2014 and 2013 was 12.6% and 12.2% , respectively.

Discrete tax expense for the quarter ended March 31, 2014 was primarily attributable to income tax expense resulting from the sale of jackup rigs ENSCO 69 and Pride Wisconsin, the recognition of a liability for unrecognized tax benefits associated with certain tax positions taken in prior years and the resolution of prior period tax matters. Discrete tax expense for the quarter ended March 31, 2013 was primarily attributable to the recognition of a liability for unrecognized tax benefits associated with a tax position taken in prior years.
  
Note 8 - Contingencies

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. Currently, only one claimant remains. 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. An accrued liability of $6.4 million for the remainder of our deductible under our liability insurance policy was included in accrued liabilities and other on our condensed consolidated balance sheets as of March 31, 2014 and December 31, 2013. In April 2014, we paid the $6.4 million balance of our deductible under our liability insurance policy. 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 currently in excess of $5.0 million for losses incurred when the tanker struck the sunken hull of ENSCO 74. This matter is currently scheduled for trial in June 2014. Based on information currently available, primarily the adequacy of available defenses, we have not concluded that it is probable a liability exists with respect to the claim by the owner of the oil tanker.
 
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.

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 Mississippi and Louisiana by approximately 100 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.

In December 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 March 31, 2014 totaled $242.7 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 March 31, 2014 , we had not been required to make collateral deposits with respect to these agreements.

Note 9 - 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 quarters ended March 31, 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.

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

17

in bankruptcy in certain circumstances and generally permitting the closeout and netting of transactions with the same counterparty upon the occurrence of certain events.  

During the quarter ended March 31, 2014 , Petrobras, Total and Anadarko Petroleum accounted for 17% , 14% and 10% of our consolidated revenues, respectively, all of which were attributable to our Floaters segment. During the same period, BP accounted for 10% of our consolidated revenues, 70% of which were attributable to our Floaters segment.

During the quarter ended March 31, 2014 , revenues provided by our drilling operations in the U.S. Gulf of Mexico totaled $419.9 million , or 35% , of our consolidated revenues, of which 75% were provided by our Floaters segment. Revenues provided by our drilling operations in Angola and Brazil during the quarter ended March 31, 2014 totaled $189.3 million and $164.5 million , or 16% and 14% , respectively, of our consolidated revenues, all of which were provided by our Floaters segment.
    
Note 11 - Guarantee of Registered Securities

On May 31, 2011, Ensco plc completed a merger transaction (the "Merger") with Pride International Inc. ("Pride"). In connection with the Merger, Ensco plc and Pride entered into a supplemental indenture to the indenture dated as of July 1, 2004 between Pride and the Bank of New York Mellon, as indenture trustee, providing for, among other matters, the full and unconditional guarantee by Ensco plc of Pride’s 8.5% unsecured senior notes due 2019 , 6.875% unsecured senior notes due 2020 and 7.875% unsecured senior notes due 2040 , which had an aggregate outstanding principal balance of $ 1.7 billion as of March 31, 2014 . The Ensco plc guarantee provides for the unconditional and irrevocable guarantee of the prompt payment, when due, of any amount owed to the holders of the notes.
 
Ensco plc is also a full and unconditional guarantor of the 7.2% debentures due 2027 issued by ENSCO International Incorporated during 1997, which had an aggregate outstanding principal balance of $ 150.0 million as of March 31, 2014 .
    
All guarantees are unsecured obligations of Ensco plc ranking equal in right of payment with all of its existing and future unsecured and unsubordinated indebtedness.

Note 12 - Subsequent Event

In April 2014, we sold jackup rig ENSCO 85 for net proceeds of approximately $64.0 million . We classified the rig as held for sale during the first quarter of 2014 and included the rig's $53.7 million aggregate net book value and inventory in other current assets on our condensed consolidated balance sheet as of March 31, 2014. The gain on sale will be recognized during the second quarter of 2014.
    
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 March 31, 2014 and for the quarter s ended March 31, 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 and elsewhere in this quarterly report. 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 76 rigs, including eight rigs under construction, spanning most of the strategic markets around the globe. Our rig fleet includes ten  drillships, 13 dynamically positioned semisubmersible rigs, six moored semisubmersible rigs and 47 jackup rigs. 

Average Brent crude oil prices exceeded $105 per barrel during the first quarter of 2014 , and we believe current prices support drilling programs by operators in the floater and jackup markets. Despite the attractive commodity prices, operators have become increasingly focused on controlling capital spending levels which, combined with increasing rig supply, has resulted in downward pressure on floater day rates and utilization.

We remain focused on our long-established strategy of high-grading and expanding the size of our fleet. In response to customer demand for our differentiated rig technology and contract drilling services in the Middle East, we recently entered into an agreement with Lamprell to construct two premium jackup rigs (ENSCO 140 and ENSCO 141). These rigs are scheduled for delivery during mid-2016. Currently, we have eight rigs under construction, including three ultra-deepwater drillships, three premium jackup rigs and two ultra-premium harsh environment jackup rigs. During 2014, we expect to take delivery of two ultra-deepwater drillships (ENSCO DS-8 and DS-9) and an ultra-premium harsh environment jackup rig (ENSCO 122).

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, $10.2 billion of contract backlog and $2.0 billion of borrowing capacity under our commercial paper program and revolving credit facility as of March 31, 2014 will provide flexibility to make additional investments in our fleet and sustain an adequate level of liquidity during the remainder of 2014 and beyond.

BUSINESS ENVIRONMENT
 
Floaters

There have been relatively few new floater contracts executed during 2014, and operators have become increasingly focused on controlling capital spending levels. Increasing rig supply from newbuild floaters and delays in customer drilling programs have negatively impacted utilization and day rates. Despite these developments, we expect additional contracting opportunities to be available in several regions, particularly for premium and high-specification rigs. Drilling contractors are currently challenged to contract older, less capable floaters, although retirements of these rigs could alleviate some of this pressure.

Rig supply in the U.S. Gulf of Mexico is expected to increase during the remainder of 2014 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. Favorable activity during the most recent lease sale in the U.S. Gulf of Mexico could lead to incremental demand in future years. In Mexico, ongoing energy reform could create opportunities in the region going forward.
 
We believe there will be incremental demand in Brazil as customers come to the market for rigs to drill their new exploration acreage awarded in licensing rounds held during 2013. Petrobras has an outstanding inquiry for at least one rig, and contract extension negotiations for multiple rigs with contracts expiring in 2015 are ongoing.

In West Africa, multiple rigs are projected to enter the region during 2014; however, this region is experiencing increasing customer demand, with additional contracting opportunities expected later this year and into 2015. In addition, several operators have exploration programs planned in East Africa and South Africa, and the new discoveries in East Africa could result in significant development programs over time.

Supply and demand in the North Sea market are balanced, and we believe there will be incremental demand for harsh environment floaters. The Mediterranean market is also expected to present additional drilling opportunities. We expect demand in the Asia Pacific market to remain stable, with incremental requirements in Australia, Indonesia, Myanmar, South Korea and Vietnam.

The worldwide supply of floaters continues to increase as a result of newbuild construction programs. Currently, there are 90 newbuild drillships and semisubmersible rigs reported to be under construction, over 20 of which are scheduled for delivery during the remainder of 2014. The majority of these rigs are not yet contracted. Utilization and day rates for less capable floaters will likely continue to be negatively impacted.

Jackups

Demand for jackups is strong, supporting current day rates and contract terms. Utilization and day rates in certain regions may come under 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.

Demand is steady in the U.S. Gulf of Mexico, and we expect the market to remain largely in balance. Contract terms in recent tenders have declined in duration, which may put pressure on day rates and utilization for certain rigs in the region. Recent lease sales indicate opportunities for favorable future demand. The national oil company of Mexico, Petróleos Mexicanos ("PEMEX"), continues to expand its rig fleet, and we believe there will be incremental demand in Mexico as PEMEX contracts additional jackups.

The Middle East market is expected to remain strong, and we believe there will be incremental demand from operators in the region. Demand also remains strong in West Africa, and there are currently open tenders for incremental rigs for multi-year terms.

We expect the North Sea market to remain tight. Significant contracted backlog exists for 2014, and operators are issuing tenders to secure rigs for work beginning in 2015 and beyond.

28

The Asia Pacific market remains balanced, and multiple newbuild rigs constructed in the region mobilized to other regions during the first quarter of 2014 to begin their initial contracts. We believe there will be incremental requirements in Australia, China, Malaysia, Thailand and Vietnam; however, uncontracted newbuild rigs scheduled for delivery from Asian shipyards during the remainder of 2014 will likely put pressure on utilization and day rates in the region.

Worldwide jackup supply continues to increase as a result of newbuild construction programs. Currently, there are approximately 130 newbuild jackup rigs reported to be under construction, over 25 of which are scheduled for delivery during the remainder of 2014. The majority of newbuild jackup rigs scheduled for delivery during 2014 are not contracted. Utilization and day rates in certain regions may come under pressure in the near to intermediate 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 quarter s ended March 31, 2014 and 2013 (in millions):

								
 	2014	 	2013	
Revenues	$	1,187.0		 	$	1,149.9

Net income attributable to noncontrolling interests	(4.2	)	 	(2.8	)	
Net income attributable to Ensco	$	292.5		 	$	317.1		
 
For the quarter ended March 31, 2014 , revenues increased $37.1 million , or 3% , and operating income declined $17.8 million , or 4% , as compared to the prior year quarter. The increase in revenues was primarily due to the addition of newbuild rigs to our Floaters segment and an increase in average day rates across our fleet, partially offset by a decline in utilization across our fleet. The decline in operating income resulted from an increase in personnel and repair and maintenance costs. 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 March 31, 2014 and 2013 :

Floaters (1)	26	 	25	
Jackups (1)(2)	42	 	42	
Under construction (1)(3)(4)	6	 	6	
Total	74	 	73	

(1)  	During the second half of 2013, we accepted delivery of one ultra-deepwater drillship (ENSCO DS-7) and two ultra-premium harsh environment jackup rigs (ENSCO 120 and ENSCO 121). ENSCO DS-7 commenced a long-term contract during the fourth quarter of 2013. ENSCO 120 commenced drilling operations under a long-term contract during the first quarter of 2014, and ENSCO 121 is expected to commence drilling operations under a long-term contract during the second quarter of 2014.	

(2)  	During the first quarter of 2014, we sold jackup rigs ENSCO 69 and Pride Wisconsin.	

(3)  	During the second quarter of 2013, we entered into an agreement with Samsung Heavy Industries ("SHI") to construct our eighth ultra-deepwater drillship (ENSCO DS-10), which is uncontracted and scheduled for delivery during the third quarter of 2015. We also entered into agreements with Keppel FELS Limited ("KFELS") during the second quarter and fourth quarter of 2013 to construct one premium jackup rig (ENSCO 110) and one ultra-premium harsh environment jackup rig (ENSCO 123), respectively. 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.	

(4)  	In April 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 mid-2016. ENSCO 140 and ENSCO 141 are not included in the table above.	
The following table summarizes our rig utilization and average day rates by reportable segment for the quarter s ended March 31, 2014 and 2013 :

								
 	2014	 	2013	
Rig Utilization (1)	 		 	 		
Floaters	68	%	 	83	%	
Jackups	84	%	 	88	%	
Total	78	%	 	86	%	
Average Day Rates (2)	 		 	 		
Floaters	$	446,801		 	$	379,801		
Jackups	130,934		 	117,268		
Total	$	238,786		 	$	209,824		

(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.	

30

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 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 the column "Reconciling Items."

Floaters

Floater revenues for the quarter ended March 31, 2014 increased by $21.3 million , or 3% , as compared to the prior year quarter. The increase in revenues was primarily due to commencement of the ENSCO DS-7 drilling contract during the fourth quarter of 2013 as well as a full quarter of operations for ENSCO DS-6 and ENSCO 8506. To a lesser extent, the increase in revenues was attributable to an increase in average day rates for various rigs in our Floater fleet. These increases were partially offset by a decline in utilization attributable to multiple rigs in our Floater fleet. ENSCO 8503 completed a contract in January 2014 and was idle for the remainder of the quarter. Additionally, ENSCO 5000 and ENSCO 5002 were warm stacked during the first quarter of 2014. ENSCO 5006, which is under contract and was mobilizing to Singapore for a capital enhancement project during the first quarter of 2014, and ENSCO 5004, which was in the shipyard for repairs and a capital enhancement project, also adversely impacted utilization. Utilization in the prior year quarter was negatively impacted by downtime prompted by a vendor notice regarding inspection and replacement of connector bolts on various rigs.

Floater contract drilling expense for the quarter ended March 31, 2014 increased by $50.8 million , or 15% , as compared to the prior year quarter, primarily due to the aforementioned additions to our 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 ENSCO 5006 and lower costs for warm stacked rigs ENSCO 5000 and ENSCO 5002. Depreciation expense increased by $8.7 million , or 8.1% , primarily due to the additions to our fleet.
    
Jackups

Jackup revenues for the quarter ended March 31, 2014 increased by $19.4 million , or 5% , as compared to the prior year quarter. The increase in revenues was primarily due to an increase in average day rates across our Jackup fleet. The increase in average day rates was partially offset by a decline in utilization, primarily due to an increase in planned downtime for shipyard upgrades and inspections as compared to the prior year quarter.
Jackup contract drilling expense for the quarter ended March 31, 2014 declined $2.8 million , or 1% , as compared to the prior year quarter, primarily due to a $23.6 million gain recognized in connection with the sale of jackup rigs ENSCO 69 and Pride Wisconsin, partially offset by an increase in personnel and repair and maintenance costs.
    
Other Income (Expense)
 
The following table summarizes other income (expense) for the quarter s ended March 31, 2014 and 2013  (in millions):

								
 	2014	 	2013	
Interest income	$	3.6		 	$	3.3		
Interest expense, net:	 	 	 		
Interest expense	(55.9	)	 	(56.8	)	
Capitalized interest	21.3		 	17.6		
 	(34.6	)	 	(39.2	)	
Other, net	1.9		 	6.1		
 	$	(29.1	)	 	$	(29.8	)	
 
Interest expense was comparable to the prior year quarter as the outstanding principal balances associated with our long-term debt instruments remained consistent. Interest expense capitalized during the quarter ended March 31, 2014 increased as compared to the prior year quarter due to an increase in the average outstanding amount of capital invested in newbuild construction.

32

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 gains of $ 1.5 million and $5.1 million were included in other, net, for the quarter s ended March 31, 2014 and 2013 , respectively. The net foreign currency exchange gain for the quarter ended March 31, 2013 was primarily attributable to the devaluation of the Venezuelan Bolivar.

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 quarters ended March 31, 2014 and 2013 was $58.7 million and $51.7 million , respectively. The $7.0 million increase in income tax expense as compared to the prior year quarter was primarily due to an increase in our consolidated effective income tax rate to 16.5% from 13.9% in the prior year quarter. Our consolidated effective income tax rate for the quarter ended March 31, 2014 includes the impact of various discrete tax items, including income tax expense resulting from the sale of ENSCO 69 and Pride Wisconsin, the recognition of a liability for unrecognized tax benefits associated with certain tax positions taken in prior years and the resolution of prior period tax matters. Excluding the impact of the aforementioned discrete tax items, our consolidated effective income tax rate for the quarters ended March 31, 2014 and 2013 was 12.6% and 12.2% , respectively.

On April 1, 2014, the U.K. government issued draft tax legislation that would significantly increase the income taxes on our U.K. drilling operations.  The draft tax legislation, which is open for technical consultation until May 9, 2014, will be included in the government’s Finance Bill 2014.  Royal Assent to Finance Bill 2014 is expected in July 2014, at which time the tax legislation will be formally enacted with retrospective application to April 1, 2014.  If the tax legislation is enacted as currently drafted, we expect our 2014 income tax expense to increase by approximately $20.0 million.

Discontinued Operations

During the first quarter of 2013, we sold jackup rig Pride Pennsylvania for net proceeds of $15.5 million . The rig was classified as held for sale and included in discontinued operations during 2012 in connection with the sale of multiple rigs in our fleet. The proceeds from the sale were included in investing activities of discontinued operations in our condensed consolidated statement of cash flows for the quarter ended March 31, 2013. We recognized a loss of $1.1 million in connection with the disposal, which was included in loss from discontinued operations, net in our condensed consolidated statement of income for the quarter ended March 31, 2013. Additionally, Pride Pennsylvania operating results were reclassified to discontinued operations in our condensed consolidated statements of income for the quarter ended March 31, 2013. There were no discontinued operations for the first quarter of 2014.

33

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.

We expect that our operating cash flows will continue to be dedicated to finance newbuild construction and upgrade projects and service our long-term debt. 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 $10.2 billion as of March 31, 2014, we believe future capital projects, debt service and dividend payments will primarily be funded from 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 quarter ended March 31, 2014 , our primary source of cash was $416.6 million generated from operating activities of continuing operations. Our primary use of cash for the same period was $274.1 million for the construction, enhancement and other improvement of our drilling rigs and  $175.7 million for dividend payments.

During the quarter ended March 31, 2013 , our primary source of cash was $342.1 million generated from operating activities of continuing operations and $15.5 million in proceeds from the sale of Pride Pennsylvania. Our primary use of cash for the same period was $168.3 million for the construction, enhancement and other improvement of our drilling rigs and $116.5 million for dividend payments.

Cash Flow and Capital Expenditures
 
Our cash flow from operating activities of continuing operations and capital expenditures for the quarter s ended March 31, 2014 and 2013 were as follows (in millions):

								
 	2014	 	2013	
Cash flow from operating activities of continuing operations	$	416.6		 	$	342.1		
Capital expenditures	 		 	 		
New rig construction	$	112.6		 	$	50.8		
Rig enhancements	101.8		 	66.0		
Minor upgrades and improvements	59.7		 	51.5		
 	$	274.1		 	$	168.3		
    
Cash flow from operating activities of continuing operations increased $74.5 million , or 22% , for the quarter ended March 31, 2014 as compared to the prior year period. The increase primarily resulted from a $160.3 million increase in cash receipts from contract drilling services, partially offset by a $72.8 million increase in cash payments related to contract drilling expenses and a $7.2 million increase in cash payments for income taxes.

We remain focused on our long-established strategy of high-grading and expanding the size of our fleet. We currently have three ultra-deepwater drillships (ENSCO DS-8, ENSCO DS-9 and ENSCO DS-10) under construction. ENSCO DS-8 is currently uncontracted and scheduled for delivery during the third quarter of 2014. ENSCO DS-9 is currently scheduled for delivery during the fourth quarter of 2014 and is committed under a long-term contract. ENSCO DS-10 is currently uncontracted and scheduled for delivery during the third quarter of 2015.

We previously entered into agreements with KFELS to construct three ultra-premium harsh environment jackup rigs (ENSCO 120, ENSCO 121 and ENSCO 122). ENSCO 120 was delivered during the third quarter of 2013 and

34

commenced drilling operations under a long-term contract in the North Sea during the first quarter of 2014. ENSCO 121 was delivered during the fourth quarter of 2013 and is expected to commence drilling operations under a long-term contract in the North Sea during the second quarter of 2014. ENSCO 122 is currently scheduled for delivery during the third quarter 2014 and is committed under a long-term drilling contract. 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 second quarter of 2016, respectively. Both of these rigs are currently uncontracted.

In April 2014, we entered into an agreement with Lamprell plc to construct two premium jackup rigs (ENSCO 140 and ENSCO 141) for estimated total construction costs of approximately $430.0 million , inclusive of costs associated with commissioning, systems integration testing and project management. ENSCO 140 and ENSCO 141 will incorporate Ensco's patented Canti-Leverage Advantage SM technology and are significantly enhanced versions of the LeTorneau Super 116E jackup design. These rigs are scheduled for delivery during mid-2016.

A substantial portion of our projected cash flows 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, $10.2 billion of contract backlog and $2.0 billion of borrowing capacity under our commercial paper program and revolving credit facility as of March 31, 2014 provide flexibility to make additional investments in our fleet and sustain an adequate level of liquidity during 2014 and beyond.
 
The following table summarizes the cumulative amount of contractual payments made as of March 31, 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)

 	 	$	616.8		 	$	752.3		 	$	1,038.9		 	$	290.6		 	$	2,698.6		

(1)  	Cumulative paid represents the aggregate amount of contractual payments made from commencement of the construction agreement through March 31, 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, are $98.6 million . 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.

35

Based on our current projections, we expect capital expenditures during 2014 to include approximately $1.2 billion for newbuild construction, approximately $570.0 million for rig enhancement projects and approximately  $300.0 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.

Senior Notes and Debentures

As of March 31, 2014 , 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 March 31, 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

We have a $2.0 billion senior unsecured revolving credit facility with a group of banks to be used for general corporate purposes with a five -year term expiring on May 7, 2018. Advances under the 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. We are required to pay a quarterly undrawn facility fee (currently 0.125% per annum) on the total $2.0 billion commitment, which is also based on our credit rating. In addition to other customary restrictive covenants, the credit facility requires us to maintain a total debt to total capitalization ratio less than or equal to 50% . We have the right, subject to lender consent, to increase the commitments under the credit facility to an aggregate amount of up to $2.5 billion . We had no amounts outstanding under the credit facility as of March 31, 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 up to a maximum aggregate amount outstanding at any time of $1.0 billion. 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 will be limited by the amount of our available and unused committed capacity under our credit facility. The proceeds of such financings will be used for capital expenditures and other general corporate purposes. The commercial paper will bear 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 March 31, 2014 and December 31, 2013 .

36

Other Financing

As of March 31, 2014 , we had an aggregate $128.0 million outstanding under our Maritime Administration bond issues due in 2015, 2016 and 2020. We make semiannual principal and interest payments on these bonds.

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 the second quarter of 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 March 31, 2014 , we were contingently liable for an aggregate amount of $242.7 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 March 31, 2014 , we had not been required to make any collateral deposits with respect to these agreements.

Liquidity
 
Our liquidity position is summarized in the table below (in millions, except ratios):

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.  

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.

38

dollars, which significantly reduces the portion of our cash flows and assets denominated in foreign currencies. As of March 31, 2014 , we had cash flow hedges outstanding to exchange an aggregate $392.2 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 March 31, 2014 , we held derivatives not designated as hedging instruments to exchange an aggregate $223.0 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 March 31, 2014 would approximate $22.8 million . Approximately $18.4 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 . These policies, along with our underlying judgments and assumptions made in their application, have a significant impact on our consolidated financial statements.

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 . During the quarter ended March 31, 2014 , there were no material changes to the judgments, assumptions or policies upon which our critical accounting estimates are based.

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. We are currently evaluating Update 2014-08 to determine the impact on the presentation of future disposals in our consolidated financial statements.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk
 
Information required under Item 3. has been incorporated into "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations - Market Risk."

Item 4.    Controls and Procedures
 
Based on their evaluation as of the end of the period covered by this quarterly report on Form 10-Q, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures, as defined in Rule 13a-15 under the Securities Exchange Act of 1934, are effective.
   
During the fiscal quarter ended March 31, 2014 , there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 the 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. In November 2012, the DOJ moved (i) to dismiss the charges against Pride and end the DPA one year prior to its scheduled expiration; and (ii) to 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.

40

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 Mississippi and Louisiana by approximately 100 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.

In December 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 consolidated balance sheet as of March 31, 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.

41

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.

Item 1A.    Risk Factors 

There are numerous factors that affect our business and results of operations, many of which are beyond our control. In addition to information set forth in this quarterly report, you should carefully read and consider "Item 1A. Risk Factors" in Part I and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II of our annual report on Form 10-K for the year ended December 31, 2013 , which contains descriptions of significant risks that might cause our actual results of operations in future periods to differ materially from those currently anticipated or expected. Except as set forth below, there have been no material changes from the risks previously disclosed in our annual report on Form 10-K for the year ended December 31, 2013.
  
Risks Related to Our Business

Our customers may be unable or unwilling to fulfill their contractual commitments to us, including their obligations to pay for losses, damages or other liabilities resulting from operations under the contract.

Certain of our customers are subject to liquidity risk and such risk could lead them to seek to repudiate, cancel or renegotiate our drilling contracts for various reasons. Our drilling contracts provide for varying levels of indemnification from our customers, including with respect to well control and subsurface risks. Our drilling contracts also provide for varying levels of indemnification and allocation of liabilities between our customers and us with respect to loss or damage to property and injury or death to persons arising from the drilling operations we perform. Under our drilling contracts, liability with respect to personnel and property customarily is allocated so that we and our customers each assume liability for our respective personnel and property. Our customers typically assume most of the responsibility for and indemnify us from any loss, damage or other liability resulting from pollution or contamination, including clean-up and removal, third-party damages, and fines and penalties arising from operations under the contract when the source of the pollution originates from the well or reservoir, including those resulting from blow-outs or cratering of the well. Notwithstanding a contractual indemnity from a customer, there can be no assurance that our customers will be financially able to assume their responsibility, or honor their indemnity to us, for such losses. This could result in the assumption of liabilities not otherwise contemplated in our contracts.

(1)  	During the quarter ended March 31, 2014 , equity securities were repurchased from employees and non-employee directors by an affiliated employee benefit trust in connection with the settlement of income tax withholding obligations arising from the vesting of share awards.  Such securities remain available for re-issuance in connection with employee share awards.	

(2)  	During the second quarter of 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.

Exhibit 32.1
CERTIFICATION PURSUANT TO
18 U.S.C. SECTION 1350,
AS ADOPTED PURSUANT TO
