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 (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act").  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; dividends; expected utilization, day rates, revenues, operating expenses, contract terms, contract backlog, capital expenditures, insurance, financing and funding; the timing of availability, delivery, mobilization, contract commencement or relocation or other movement of rigs and the timing thereof; 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; the offshore drilling market, including supply and demand, customer drilling programs, stacking of rigs, effects of new rigs on the market and effects of declines in commodity prices; general market, business and industry conditions, trends and outlook; future operations; the impact of increasing regulatory complexity; 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 or contract disputes 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, 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 as a result of delivery of newbuild drilling rigs;	

•	changes in future levels of drilling activity and expenditures by our customers, 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 suspension and/or termination of contracts based on force majeure events;	

•	risks inherent to shipyard rig construction, repair, modification or upgrades, unexpected delays in equipment delivery, engineering, design or commissioning issues following delivery, or changes in the commencement, completion or service dates;	

•	possible cancellation, suspension, renegotiation or termination (with or without cause) of drilling contracts as a result of general and industry-specific economic conditions, mechanical difficulties, performance or other reasons;	

•	our ability to enter into, and the terms of, future drilling contracts, including contracts for our newbuild units, for rigs currently idled and for rigs whose contracts are expiring;	

1

		
•	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 renegotiation, nullification, cancellation or breach of contracts with customers or other parties and any failure to execute definitive contracts following announcements 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);	

•	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, operations or financial results;	

•	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, damages or losses, whether related to storms or hurricanes (including wreckage or debris removal), collisions, groundings, blowouts, fires, explosions, other accidents, 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, debt agreement restrictions and the credit ratings assigned to our debt by independent credit rating agencies;	

•	tax matters, including our effective tax rates, tax positions, results of audits, changes in tax laws, treaties and regulations, tax assessments and liabilities for taxes;	

•	delays in contract commencement dates or the cancellation of drilling programs by operators;	

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

•	potential long-lived asset 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, 2015, which is available on the U.S. Securities and Exchange Commission 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 September 30, 2016 , the related condensed consolidated statements of operations and comprehensive income for the three-month and nine-month periods ended September 30, 2016 and 2015 , and the related condensed consolidated statements of cash flows for the nine-month periods ended September 30, 2016 and 2015 . These condensed consolidated financial statements are the responsibility of the Company’s management.
We conducted our review 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, 2015 , and the related consolidated statements of operations, comprehensive (loss) income, and cash flows for the year then ended (not presented herein); and in our report dated February 24, 2016 , 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, 2015 , 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, 2015 condensed consolidated balance sheet data were derived from our 2015 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 us 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, 2016 and 2015 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, 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, 2016 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2016 .  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, 2015 filed with the SEC on February 24, 2016 and our quarterly reports on Form 10-Q filed with the SEC on April 28, 2016 and July 28, 2016 .

Operating Revenues and Expenses

During the nine-month period ended September 30, 2016 , operating revenues included $185.0 million for the lump-sum consideration received in settlement and release of the ENSCO DS-9 customer's ongoing early termination obligations. The ENSCO DS-9 contract was terminated for convenience by the customer in July 2015, whereby our customer was obligated to pay us monthly termination fees for two years under the termination provisions of the contract. Operating revenues also included $20.0 million for the lump-sum consideration received in settlement of the ENSCO 8503 customer's remaining obligations under the contract. The lump-sum settlements for the ENSCO DS-9 termination obligations and ENSCO 8503 remaining contractual obligations were collected in June 2016.

During the three-month and nine-month periods ended September 30, 2015, operating revenues included $129.0 million related to lump-sum payments associated with the ENSCO DS-4 and ENSCO DS-9 contract terminations.

New Accounting Pronouncements

In October 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“Update 2016-16”), which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transaction occurs as opposed to deferring tax consequences and amortizing them into future periods. This update is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. A modified retrospective approach with a cumulative-effect adjustment directly to retained earnings at the beginning of the period of adoption is required. We are currently evaluating the effect that Update 2016-16 will have on our condensed consolidated financial statements and related disclosures.
In August 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-15, Statement of Cash flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("Update 2016-15"), which addresses the cash flow presentation of eight specific cash flow issues including, debt repayment and extinguishment costs, with the objective of reducing the existing diversity in practice. This update is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. We do not anticipate that our adoption of Update 2016-15 will have a material impact on our condensed consolidated financial statements and related disclosures.

In March 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("Update 2016-09"), which simplifies several aspects of accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. Transition methods vary for the related amendments. We will apply Update 2016-09 in our Annual Report on Form 10-K for the year ended December 31, 2016. We do not anticipate that our adoption of Update 2016-09 will have a material impact on our condensed consolidated financial statements and related disclosures.

In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification ("Update 2016-02"), which requires an entity to recognize lease assets and lease liabilities on the balance sheet and to disclose key qualitative and quantitative information about the entity's leasing arrangements. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. A modified retrospective approach is required. We are currently evaluating the effect that Update 2016-02 will have on our condensed consolidated financial statements and related disclosures.

During 2015, the Financial Accounting Standards Board issued Accounting Standards Update 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs ("Update 2015-03"), as updated by Update 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcements at June 18, 2015 EITF Meeting ("Update 2015-15"), which require that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts. Debt issuance costs related to line-of-credit arrangements may be presented as an asset regardless of whether there are any outstanding borrowings on the arrangement. We adopted Update 2015-03 and Update 2015-15 on a retrospective basis effective January 1, 2016. Accordingly, all debt issuance costs, except for the balance related to our line-of-credit arrangement, were presented as a deduction from the carrying amount of the related debt liability on our condensed consolidated balance sheet for all periods presented. As a result of retrospective application, we reclassified debt issuance costs of $26.5 million on our condensed consolidated balance sheet as of December 31, 2015. There is no impact to the manner in which debt issuance costs are amortized in our condensed consolidated financial statements.

During 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. During

11

2015, the Financial Accounting Standards Board voted to delay the effective date one year. Update 2014-09 is now effective for annual and interim periods for fiscal years beginning after December 15, 2017, though companies have an option of adopting the standard for fiscal years beginning after December 15, 2016. During 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ("Update 2016-08"), Accounting Standards Update 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ("Update 2016-10") and Account Standards Update 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ("Update 2016-12"). The amendments in Update 2016-08, 2016-10 and 2016-12 do not change the core principle of Update 2014-09 but instead clarify the implementation guidance on principle versus agent considerations, identify performance obligations and the licensing implementation guidance, and provide narrow-scope improvements, respectively. Update 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP and may be adopted using a retrospective, modified retrospective or prospective with a cumulative catch-up approach. We are currently evaluating the effect that Update 2014-09 will have on our condensed 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, in 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.

Total	$	4,702.6		 	$	3,730.2		 	$	5,868.6		 	$	4,621.9		

The estimated fair values of our senior notes and debentures were determined using quoted market prices. The decline in the carrying value of long-term debt instruments from December 31, 2015 to September 30, 2016 is due to debt repurchases as discussed in "Note 6 - Debt." 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 September 30, 2016 and December 31, 2015 . Our short-term investments consisted of time deposits with initial maturities in excess of three months but less than one year as of each respective balance sheet date.

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. 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 in 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 derivative fair value depends on the use of the derivative and whether it qualifies for hedge accounting.  Net liabilities of $4.3 million and $19.7 million associated with our foreign currency forward contracts were included in our condensed consolidated balance sheets as of September 30, 2016 and December 31, 2015 , 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.

(1)  	Derivative assets and liabilities with maturity dates equal to or less than twelve months from the respective balance sheet date were included in other current assets and accrued liabilities and other, respectively, in our condensed consolidated balance sheets.	

(2)  	Derivative assets and liabilities with maturity dates greater than twelve months from the respective balance sheet date were included in other assets, net, and other liabilities, respectively, in 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, 2016 , we had cash flow hedges outstanding to exchange an aggregate $204.0 million for various foreign currencies, including $95.9 million for British pounds, $40.5 million for Australian dollars, $30.3 million for euros, $23.4 million for Brazilian reais and $13.9 million for other currencies.

Gains and losses, net of tax, on derivatives designated as cash flow hedges included in our condensed consolidated statements of operations and comprehensive income were as follows (in millions):

(1)	Changes in the effective portion of cash flow hedge fair values 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 operations.	

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

(4)  	During the three-month period ended September 30, 2016 , $2.3 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. During the three-month period ended September 30, 2015 , $5.9 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, 2016 , $10.5 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. During the nine-month period ended September 30, 2015 , $15.9 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, 2016 , we held derivatives not designated as hedging instruments to exchange an aggregate $144.1 million for various foreign currencies, including $81.3 million for euros, $18.2 million for Swiss francs, $13.1 million for British pounds, $11.4 million for Indonesian rupiah, $10.7 million for Brazilian reais and $9.4 million for other currencies.

15

Net losses of $400,000 and $4.2 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, 2016 and 2015 , respectively. Net gains of $500,000 and net losses of $13.2 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, 2016 and 2015 , respectively. These gains and losses were largely offset by net foreign currency exchange gains and losses during the respective periods.

As of September 30, 2016 , 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 $2.4 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 in our condensed consolidated balance sheets, and net income attributable to noncontrolling interests is presented separately in our condensed consolidated statements of operations.
    
Income from continuing operations attributable to Ensco for the three-month and nine-month periods ended September 30, 2016 and 2015 was as follows (in millions):

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.

Note 6 - Debt

Tender Offers and Open Market Repurchases

In March 2016, we launched cash tender offers (the "Tender Offers") to repurchase up to $750.0 million aggregate purchase price of our outstanding debt. We received tenders totaling $860.7 million for an aggregate purchase price of $622.3 million . In April, we used cash on-hand to settle the tendered debt.

During the three-month and nine-month period ended September 30, 2016, we repurchased on the open market $188.7 million and $268.2 million of outstanding debt for an aggregate purchase price of $177.3 million and $239.8 million , respectively.

17

Our Tender Offers and open market repurchases during the nine-month period ended September 30, 2016 were as follows (in millions):

												
 	 	Aggregate Principal Amount Repurchased	 	Aggregate Repurchase Price (1)	 	Discount %	
8.50% Senior Notes due 2019	 	$	60.3		 	$	53.9		 	10.6	%

Total	 	$	1,128.9		 	$	862.1		 	23.6	%	
		
(1)  	The aggregate repurchase price excludes accrued interest.	
During the three-month and nine-month periods ended September 30, 2016, we recognized pre-tax gains from debt extinguishment of $18.2 million and $279.0 million , respectively, included in other, net, in our consolidated statements of operations related to the Tender Offers and open market repurchases, net of discounts, premiums, debt issuance costs and transaction costs.

After giving effect to the debt maturities impacted by the Tender Offers and open market repurchases, our next debt maturity is $439.9 million during 2019, followed by $680.8 million , $683.0 million , $623.2 million and $669.3 million during 2020, 2021, 2024 and 2025, respectively.

Revolving Credit

We have a $2.25 billion senior unsecured revolving credit facility with a syndicate of banks to be used for general corporate purposes with a term expiring on September 30, 2019 (the "Credit Facility"). In October, we extended the maturity of $1.13 billion of the $2.25 billion commitment for one year to September 30, 2020 . All other terms of the Credit Facility are unchanged. Advances under the Credit Facility bear interest at Base Rate or LIBOR plus an applicable margin rate, depending on our credit ratings. We are required to pay a quarterly commitment fee on the undrawn portion of the commitment, which is also based on our credit rating.

In February, Moody’s announced a downgrade of our credit rating to B1, which is below investment grade. Following the downgrade, the applicable margin rates are 0.50% per annum for Base Rate advances and 1.50% per annum for LIBOR advances. Our quarterly commitment fee is 0.225% per annum on the undrawn portion of the commitment. 

In July, Standard & Poor's downgraded our credit rating one notch to BBB-, which maintains our investment grade rating with the rating agency. As previous rating actions resulted in the highest applicable margin rate and commitment fees under our Credit Facility, the July downgrade did not impact our applicable margin rate on borrowings or our quarterly commitment fee. We have limited or no access to the commercial paper market as a result of our current credit ratings.

The Credit Facility requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60% . The Credit Facility also contains customary restrictive covenants, including, among others, prohibitions on creating, incurring or assuming certain debt and liens; entering into certain merger arrangements; selling, leasing, transferring or otherwise disposing of all or substantially all of our assets; making a material change in the nature of the business; and entering into certain transactions with affiliates. We have the right, subject to receipt of commitments from new or existing lenders, to increase the commitments under the Credit Facility by an amount not exceeding $500 million and to extend the maturity of the commitments under the Credit Facility by one additional year.

18

As of September 30, 2016 , we were in compliance in all material respects with our covenants under the Credit Facility. We had no amounts outstanding under the Credit Facility as of September 30, 2016 and December 31, 2015 .

Our access to credit and capital markets depends on the credit ratings assigned to our debt. There can be no assurance that we will be able to maintain our credit ratings, and any additional actual or anticipated downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could limit our available options when accessing credit and capital markets, or when restructuring or refinancing our debt. In addition, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants.

Note 7 - Shareholders' Equity

In April 2016, we closed an underwritten public offering of 65,550,000 Class A ordinary shares at $9.25 per share, inclusive of shares purchased under an underwriters' option. We received net proceeds from the offering of $585.5 million . The offering resulted in an increase in Class A ordinary shares and Additional Paid-in Capital in our condensed consolidated balance sheet of $6.6 million and $578.9 million , respectively.

On October 1, 2016, we entered into a privately-negotiated exchange agreement whereby we issued 1,822,432 Class A ordinary shares in exchange for $24.5 million principal amount of our 5.75% Senior Notes due 2044. The $24.5 million principal, net of unamortized debt issuance costs and discounts, is classified as current maturities of long term debt on our condensed consolidated balance sheet as of September 30, 2016. A gain of approximately $9.0 million from the exchange will be recognized during the fourth quarter. Upon settlement of this transaction, the outstanding principal amount of our 5.75% Senior Notes due 2044 declined from $1.025 billion to $1.0 billion .

During the nine-month period ended September 30, 2016 , we sold ENSCO DS-2, ENSCO 6000 and ENSCO 58 for scrap value resulting in a net pre-tax gain on sale of $1.2 million included in loss from discontinued operations, net, in our condensed consolidated statements of operations.

ENSCO 7500 and ENSCO 90 remain classified as held-for-sale in our September 30, 2016 condensed consolidated balance sheet and are included in discontinued operations.

For the three-month and nine-month period ended September 30, 2015 , loss from discontinued operations, net, included pre-tax impairment losses of $25.6 million and $32.8 million , respectively, as a result of declines in the estimated fair values of several held-for-sale rigs, the operating results of ENSCO 93 and ENSCO 58, and stacking costs for uncontracted rigs included in discontinued operations. A discrete tax benefit of $11.9 million was included in loss from discontinued operations, net, in the nine-month period ended September 30, 2015.

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

Note 9 - Income Taxes
 
Our consolidated effective income tax rate for the three-month and nine-month periods ended September 30, 2016 , excluding the impact of discrete tax items, was 6.0% and 21.9% , respectively. Discrete tax items for the three-month and nine-month period ended September 30, 2016 were primarily attributable to the gain on debt extinguishment, changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and other resolutions of prior year tax matters. Discrete tax items for the nine-month period ended September 30, 2016 also resulted from restructuring transactions involving certain of our subsidiaries.

Our consolidated effective income tax rate for the three-month and nine-month periods ended September 30, 2015 excluding the impact of discrete tax items, was 12.6% and 16.4% , respectively. Discrete tax items for the three-month and nine-month periods were primarily attributable to the early termination of the ENSCO DS-4 drilling contract and the recognition of liabilities for unrecognized tax benefits associated with tax positions taken in prior years.

The changes in our consolidated effective tax rate, excluding discrete items, for the three-month and nine-month periods ended September 30, 2016 as compared to the prior year period is primarily attributable to changes in the relative components of our estimated 2016 earnings, excluding discrete items, generated in tax jurisdictions with higher tax rates and to the impact of 2016 restructuring transactions involving certain of our subsidiaries.

Note 10 - Contingencies
Brazil Internal Investigation

Pride International, Inc. (“Pride”), a company we acquired in 2011, commenced drilling operations in Brazil in 2001. In 2008, Pride entered into a drilling services agreement with Petrobras (the "DSA") for ENSCO DS-5, a drillship ordered from Samsung Heavy Industries, a shipyard in South Korea ("SHI"). Beginning in 2006, Pride conducted periodic compliance reviews of its business with Petrobras, and, after the acquisition of Pride, Ensco conducted similar compliance reviews, the most recent of which commenced in early 2015 after media reports were released regarding ongoing investigations of various kickback and bribery schemes in Brazil involving Petrobras.

While conducting our compliance review, we became aware of an internal audit report by Petrobras alleging irregularities in relation to the DSA. Upon learning of the Petrobras internal audit report, our Audit Committee appointed independent counsel to lead an investigation into the alleged irregularities. Further, in June and July 2015, we voluntarily contacted the SEC and the DOJ, respectively, to advise them of this matter and our Audit Committee’s investigation. Independent counsel, under the direction of our Audit Committee, has substantially completed its investigation by reviewing and analyzing available documents and correspondence and interviewing current and former employees involved in the DSA negotiations and the negotiation of the ENSCO DS-5 construction contract with SHI (the "DS-5 Construction Contract").
    
To date, our Audit Committee has found no evidence that Pride or Ensco or any of their current or former employees were aware of or involved in any wrongdoing, and our Audit Committee has found no evidence linking Ensco or Pride to any illegal acts committed by our former marketing consultant, who provided services to Pride and Ensco in connection with the DSA. Independent counsel has continued to provide the SEC and DOJ with updates throughout the investigation, including detailed briefings regarding its investigation and findings. On December 21, 2015, we entered into a one-year tolling agreement with the DOJ. On March 7, 2016, we entered into a one-year tolling agreement with the SEC.

Subsequent to initiating our Audit Committee investigation, Brazilian court documents connected to the prosecution of former Petrobras directors and employees as well as certain other third parties, including our former marketing consultant, referenced the alleged irregularities cited in the Petrobras internal audit report. Our former marketing consultant has entered into a plea agreement with the Brazilian authorities. On January 10, 2016, Brazilian authorities filed an indictment against a former Petrobras director. This indictment states that the former Petrobras director received bribes paid out of proceeds from a brokerage agreement entered into for purposes of intermediating

20

a drillship construction contract between SHI and Pride, which we believe to be the DS-5 Construction Contract. The parties to the brokerage agreement were a company affiliated with a person acting on behalf of the former Petrobras director, a company affiliated with our former marketing consultant, and SHI. The indictment alleges that amounts paid by SHI under the brokerage agreement ultimately were used to pay bribes to the former Petrobras director. The indictment does not state that Pride or Ensco or any of their current or former employees were involved in the bribery scheme or had any knowledge of the bribery scheme.    

On January 4, 2016, we received a notice from Petrobras declaring the DSA void effective immediately. Petrobras’ notice alleges that our former marketing consultant both received and procured improper payments from SHI for employees of Petrobras and that Pride had knowledge of this activity and assisted in the procurement of and/or facilitated these improper payments. We disagree with Petrobras’ allegations. See "—DSA Dispute" below for additional information.

Outside of Petrobras’ allegations, we have not been contacted by any Brazil governmental authority regarding alleged wrongdoing by Pride or Ensco or any of their current or former employees related to this matter. We cannot predict whether any U.S., Brazilian or other governmental authority will seek to investigate Pride's involvement in this matter, or if a proceeding were opened, the scope or ultimate outcome of any such investigation. If the SEC or DOJ determines that violations of the FCPA have occurred, or if any governmental authority determines that we have violated applicable anti-bribery laws, they could seek civil and criminal sanctions, including monetary penalties, against us, as well as changes to our business practices and compliance programs, any of which could have a material adverse effect on our business and financial condition. Although our internal investigation is substantially complete, we cannot predict whether any additional allegations will be made or whether any additional facts relevant to the investigation will be uncovered during the course of the investigation and what impact those allegations and additional facts will have on the timing or conclusions of the investigation. Our Audit Committee will examine any such additional allegations and additional facts and the circumstances surrounding them.

DSA Dispute

As described above, on January 4, 2016, Petrobras sent a notice to us declaring the DSA void effective immediately, reserving its rights and stating its intention to seek any restitution to which it may be entitled. We disagree with Petrobras’ declaration that the DSA is void. We believe that Petrobras has repudiated the DSA and have therefore accepted the DSA as terminated on April 8, 2016 (the "Termination Date"). At this time, we cannot reasonably determine the validity of Petrobras' claim or the range of our potential exposure, if any. As a result, there can be no assurance as to how this dispute will ultimately be resolved.

We did not recognize revenue for amounts owed to us under the DSA from the beginning of the fourth quarter of 2015 through the Termination Date, as we concluded that collectability of these amounts was not reasonably assured. Additionally, our receivables from Petrobras related to the DSA from prior to the fourth quarter of 2015 are fully reserved in our condensed consolidated balance sheet as of September 30, 2016 . We have initiated arbitration proceedings in the U.K. against Petrobras seeking payment of all amounts owed to us under the DSA, in addition to any other amounts to which we are entitled, and intend to vigorously pursue our claims. Petrobras subsequently filed a counterclaim seeking restitution of certain sums paid under the DSA less value received by Petrobras under the DSA. We have also initiated separate arbitration proceedings in the U.K. against SHI for any losses we have incurred in connection with the foregoing. There can be no assurance as to how these arbitration proceedings will ultimately be resolved.

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  43 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  plaintiffs to settle lawsuits filed in Mississippi for a nominal amount. A special master reviewed all  58  cases and made an allocation of settlement funds among the parties.  The District Court Judge reviewed the allocations and accepted the special master’s recommendations and approved the settlements.  The settlement documents for most of the individual plaintiffs have been processed, and the cases dismissed. The settlement documents for approximately 10 individual plaintiffs continue to be processed.

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, 2016 totaled $61.3 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, 2016 , we were not required to make collateral deposits with respect to these agreements.

Note 11 - 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 2016 and 2015 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 are 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 derivative counterparties 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 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, 2016 and for the three-month and nine-month periods ended September 30, 2016 and 2015 included elsewhere herein and with our annual report on Form 10-K for the year ended December 31, 2015 . 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

Our Business

We are one of the leading providers of offshore contract drilling services to the international oil and gas industry. We currently own and operate an offshore drilling rig fleet of 58 rigs, with drilling operations in most of the strategic markets around the globe. We also have  three rigs under construction. Our rig fleet consists of eight drillships, 10 dynamically positioned semisubmersible rigs, three moored semisubmersible rigs and 40 jackup rigs. We operate the world's second largest fleet amongst competitive rigs, including one of the newest ultra-deepwater fleets in the industry, and a leading premium jackup fleet.

Our Industry

The contracting environment remained very challenging for offshore drilling contractors during the third quarter with customers exploring subletting opportunities for contracted rigs as well as requesting contract concessions or terminating drilling contracts. Crude oil prices have ranged from $26 to $51 per barrel during 2016, reaching a 12-year low in February. The sustained decline in oil prices from 2014 highs has caused a significant decline in demand for offshore drilling services as many projects have become uneconomical, resulting in few market tenders in recent periods. Operators continue to significantly reduce their capital spending budgets, including the cancellation or deferral of existing programs, and are expected to continue operating under reduced budgets in the current commodity price environment. Declines in capital spending levels, together with the oversupply of rigs, have resulted in significantly reduced day rates and utilization, and we expect this trend to continue. Although oil prices have stabilized between $40 and $50 per barrel, we do not expect a meaningful improvement in demand for offshore drilling services in the near-term. When market conditions improve, we expect jackup demand to improve first as shallow-water drilling is typically shorter term in nature, requires less capital investment and generally presents less risk to operators.

In general, recent contract awards have been short-term in nature and subject to an extremely competitive bidding process. The intense pressure on operating day rates has resulted in rates that approximate, or are slightly lower than, direct operating expenses. In addition, we are seeing increased pressure to accept other less favorable contractual and commercial terms, including reduced or no mobilization and/or demobilization fees; reduced day rates during downtime; reduced standby, redrill and moving rates; caps on reimbursements for downhole tools; reduced periods to remediate equipment breakdowns; certain limitations on our ability to be indemnified; increases in the nature and amounts of liability allocated to us; and reduced early termination fees and/or termination notice periods.

41

Liquidity Position

We have historically relied on our cash flow from continuing operations to meet liquidity needs and fund the majority of our cash requirements. We periodically rely on the issuance of debt and/or equity securities to supplement our liquidity needs. Based on our balance sheet, our contractual backlog and $2.25 billion available under our revolving credit facility, we expect to fund our short-term and long-term liquidity needs, including contractual obligations and anticipated capital expenditures, as well as working capital requirements, from cash and cash equivalents, short-term investments, operating cash flows, and, if necessary, funds borrowed under our revolving credit facility or other future financing arrangements. Notwithstanding our current liquidity position, significant further deterioration in demand for offshore drilling could have a material adverse effect on our ability to meet our financial obligations.

Equity Transactions

In April 2016, we closed an underwritten public offering of 65,550,000 Class A ordinary shares at $9.25 per share, inclusive of shares purchased under an underwriters' option. We received net proceeds from the offering of $585.5 million .

On October 1, 2016, we entered into a privately-negotiated exchange agreement whereby we issued 1,822,432 Class A ordinary shares in exchange for $24.5 million principal amount of our 5.75% Senior Notes due 2044. A gain of approximately $9.0 million from the exchange will be recognized during the fourth quarter. Upon settlement of this transaction, the outstanding principal amount of our 5.75% Senior Notes due 2044 declined from $1.025 billion to $1.0 billion.

Cash and Debt

As of September 30, 2016, we had $4.7 billion in total debt outstanding, representing approximately 37% of our total capitalization. We also had $1.8 billion in cash and cash equivalents and short-term investments and a $2.25 billion undrawn senior unsecured revolving credit facility (the "Credit Facility") with a term that expires in September 2019. In October 2016, we extended the maturity of $1.13 billion of the $2.25 billion Credit Facility commitment for one year to September 30, 2020 . All other terms of the Credit Facility are unchanged. The Credit Facility requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60%.

During the third quarter, we repurchased $188.7 million of our senior notes for $177.3 million on the open market. During the second quarter, we repurchased $940.2 million of our senior notes for $684.8 million through tender offers and open market repurchases.

During the three-month and nine-month periods ended September 30, 2016, we recognized pre-tax gains from debt extinguishments of $18.2 million and $279.0 million , respectively, included in other, net, in our condensed consolidated statements of operations related to the tender offers and open market repurchases, net of discounts, premiums, debt issuance costs and transaction costs.

After giving effect to the debt maturities impacted by the tender offers and open market repurchases transacted through September 30, 2016, our next debt maturity is $439.9 million during 2019, followed by $680.8 million , $683.0 million , $623.2 million and $669.3 million during 2020, 2021, 2024 and 2025, respectively.

Backlog

As of September 30, 2016, our backlog was $3.8 billion as compared to $5.8 billion as of December 31, 2015. Our backlog declined primarily due to revenues realized during the first nine months of the year, various contract terminations and reduced day rates on our jackup rigs contracted with Saudi Aramco, partially offset by contract extensions at reduced rates and various short-term contract awards.

42

As current contracts expire, we will likely experience further declines in backlog for the remainder of the year and into 2017. Our declining backlog, coupled with lower demand, will result in a decline in revenues and operating cash flows for the remainder of 2016 and into 2017.

BUSINESS ENVIRONMENT
 
Floaters

The floater contracting environment continues to be challenged by reduced demand, as well as excess newbuild supply. Floater demand has declined significantly due to lower commodity prices which have caused our customers to rationalize capital expenditures, resulting in the cancellation and delay of drilling programs. In addition, certain customers are exploring subletting opportunities for contracted rigs as well as requesting contract concessions or terminating or otherwise repudiating drilling contracts. We expect this trend to continue until we see a meaningful recovery in commodity prices.

In the first part of the year, we executed contract extensions for ENSCO 5004 and ENSCO 5006 at lower rates. We agreed to reduce the ENSCO 6001 contracted rate and early terminate ENSCO 6003 and ENSCO 6004 in exchange for extension of the ENSCO 6002 contract term at a reduced rate. We also received a termination notice on ENSCO 8505 and agreed to lump-sum settlements of ongoing obligations for ENSCO DS-9 and ENSCO 8503. In addition, we sold five floaters for scrap value resulting in insignificant pre-tax gains and losses, two of which were included in discontinued operations, net, in our condensed consolidated statements of operations.

In August, we received a notice of early termination for convenience from our ENSCO DS-7 customer working in Angola. The contract ended in October 2016. The drilling contract obligates the customer to pay us termination fees through November 2017. The first 90 days following the end of the contract are payable at the full operating day rate, and the remaining days are payable at 75% of the operating rate. The customer's termination fee obligation will be defrayed should we re-contract the rig over the remainder of the original contract term.

Currently, there are approximately 60 competitive newbuild drillships and semisubmersible rigs reported to be under construction, of which approximately 25 are scheduled to be delivered by the end of 2017. Most newbuild floaters are uncontracted. Several newbuild deliveries have already been delayed into future years, and we expect that more uncontracted newbuilds will be delayed or cancelled.
Drilling contractors have retired 64 floaters over the past two years due to a lack of contracting opportunities. Approximately 40 floaters older than 30 years of age are currently idle. Approximately 30 additional floaters greater than 30 years old have contracts that will expire by the end of 2017 without follow-on work. Operating costs associated with keeping these rigs idle as well as expenditures required to recertify these aging rigs may prove cost prohibitive. Drilling contractors will likely elect to scrap or cold-stack some or all of these rigs. We expect floater scrapping and cold-stacking to continue for the remainder of 2016 and 2017.
Jackups

Jackup demand also declined due to lower commodity prices. As customers continue to rationalize spending, they have cancelled and delayed drilling programs. In addition, certain customers are requesting contract concessions or terminating drilling contracts. We expect that jackup day rates and utilization will remain under pressure until we see a meaningful recovery in commodity prices.
In the first half of the year, we agreed to reduced rates on our jackups contracted with Saudi Aramco and received termination notices on ENSCO 72, ENSCO 75, ENSCO 83 and ENSCO 110. In addition, we sold two jackups for scrap value, one of which was included in discontinued operations, net, in our condensed consolidated statements of operations, resulting in insignificant pre-tax gains.

43

During the third quarter, we reached agreement with our ENSCO 94 and ENSCO 88 customer to extend the terms of these contracts for five and three years, respectively. We subsequently reached an agreement with the customer to substitute ENSCO 84 for ENSCO 94 for the duration of the contract. We also executed several short-term contracts with various customers for ENSCO 67, ENSCO 72 and ENSCO 101 with terms ranging from six to 12 months.
In September, we executed agreements to sell ENSCO 53 and ENSCO 94 for scrap value and expect the sales to close during the fourth quarter.
Currently, there are approximately 100 competitive newbuild jackup rigs reported to be under construction, of which approximately 90 are scheduled to be delivered by the end of 2017. Most newbuild jackups are uncontracted. Over the past year, some jackup orders have been cancelled, and many newbuild jackups have been delayed. We expect that additional rigs may be delayed or cancelled given limited contracting opportunities.

Over the past two years, drilling contractors have retired 23 competitive jackups. Currently, approximately 90 marketed jackups older than 30 years of age are idle. Furthermore, approximately 55 jackups that are 30 years of age or older have contracts that expire by the end of 2017 without follow-on work. Expenditures required to recertify these aging rigs may prove cost prohibitive and drilling contractors may instead elect to scrap or cold-stack these rigs. Although not significant to date, we expect jackup scrapping and cold-stacking to accelerate during 2017.

Excluding the impact of ENSCO DS-4 and ENSCO DS-9 lump-sum termination payments of $129.0 million during the third quarter of 2015, revenues for the three-month period ended September 30, 2016 declined $335.0 million , or 38% , as compared to the prior year quarter primarily due to fewer days under contract across the fleet, lower average day rates, the contract terminations and ultimate sale of ENSCO 6003 and ENSCO 6004 and lower revenues from jackups that were undergoing shipyard projects during the current quarter. This decline was partially offset by the commencement of ENSCO DS-8 drilling operations.

44

Excluding the impact of ENSCO DS-9 and ENSCO 8503 lump-sum termination payments of $185.0 million and $20.0 million , respectively, received during the second quarter of 2016 and the lump-sum payments related to ENSCO DS-4 and ENSCO DS-9 contract terminations during the prior year period, revenues for the nine-month period ended September 30, 2016 declined $1.0 billion , or 33% , as compared to the prior year period primarily due to fewer days under contract across the fleet, lower average day rates and the contract terminations and ultimate sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1. This decline was partially offset by commencement of ENSCO DS-8 drilling operations and revenues from various rigs that were undergoing shipyard projects during the prior year period.

Contract drilling expense declined $135.4 million , or 31% , and $442.4 million , or 30% , for the three-month and nine-month periods ended September 30, 2016 , respectively, as compared to the prior year periods primarily due to rig stackings and other cost control initiatives that reduced offshore personnel costs and daily rig operating expenses and the contract terminations and ultimate sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1. These declines were partially offset by ENSCO DS-8 contract drilling expense.

Depreciation expense declined $35.8 million , or 25% , and $87.7 million , or 21% , for the three-month and nine-month periods ended September 30, 2016 , respectively, as compared to the prior year periods primarily due to lower depreciation expense on rigs that were impaired during 2015, partially offset by the addition of ENSCO DS-8 and ENSCO 110 to the active fleet.

General and administrative expenses declined $3.1 million , or 11% , and $12.1 million , or 14% , for the three-month and nine-month periods ended September 30, 2016, respectively, as compared to the prior year periods primarily due to lower shore-based headcount levels.

Other income (expense), net, for the three-month and nine-month periods ended September 30, 2016 included pre-tax gains on debt extinguishment of $18.2 million and $279.0 million , respectively. Other income expense, net, for the nine-month period ended September 30, 2015 included a pre-tax loss on debt extinguishment of $33.5 million related to make-whole premiums on our 2015 debt redemption.
 
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. We expect operating results to decline during 2016 and into 2017 as long-term contracts expire, and our rigs either go uncontracted or we renew contracts at significantly lower rates.

(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 early contract terminations, 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 the 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.  	

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."

Floaters

Excluding the impact of ENSCO DS-4 and ENSCO DS-9 lump-sum termination payments of $129.0 million during the third quarter of 2015, floater revenues for the three-month period ended September 30, 2016 declined $198.1 million , or 38% , as compared to the prior year quarter primarily due to fewer days under contract across the floater fleet, the contract terminations and ultimate sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1 and lower average day rates. This decline was partially offset by the commencement of ENSCO DS-8 drilling operations.

Excluding the impact of ENSCO DS-9 and ENSCO 8503 lump-sum termination payments of $185.0 million and $20.0 million , respectively, received during the second quarter of 2016 and the lump-sum payments related to ENSCO DS-4 and ENSCO DS-9 contract terminations during the prior year period, floater revenues for the nine-month period ended September 30, 2016 declined $583.4 million , or 32% , as compared to the prior year period primarily due to fewer days under contract across the floater fleet, lower average day rates and the contract terminations and ultimate sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1. This decline was partially offset by the commencement of ENSCO DS-8 drilling operations and additional ENSCO 5006 days under contract.

Floater contract drilling expense for the three-month and nine-month periods ended September 30, 2016 declined $88.7 million , or 37% , and $240.0 million , or 29% , respectively, as compared to the prior year periods primarily due to rig stackings and other cost control initiatives that reduced offshore personnel costs and daily rig operating expenses as well as the contract terminations and ultimate sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1. These declines were partially offset by ENSCO DS-8 contract drilling expense.

Floater depreciation expense declined $22.8 million , or 24% , and $52.1 million , or 18% , for the three-month and nine-month periods ended September 30, 2016 , respectively, as compared to the prior year periods primarily due to lower depreciation on floaters that were impaired during 2015, partially offset by the addition of ENSCO DS-8 to the active fleet.

Jackups

Jackup revenues for the three-month period ended September 30, 2016 declined $112.0 million , or 34% , as compared to the prior year quarter primarily due to fewer days under contract across the jackup fleet, lower average day rates and various jackup rigs undergoing shipyard projects during the current quarter.
Jackup revenues for the nine-month period ended September 30, 2016 declined $395.2 million , or 35% , as compared to the prior year period primarily due to fewer days under contract across the jackup fleet and lower average day rates. This decline was partially offset by various jackup rigs undergoing shipyard projects during the prior year period and the commencement of ENSCO 110 drilling operations.
Jackup contract drilling expense for the three-month and nine-month periods ended September 30, 2016 declined $26.8 million , or 17% , and $154.2 million , or 28% , respectively, as compared to the prior year periods due to rig stackings and other cost control initiatives that reduced offshore personnel costs and daily rig operating expenses and lower repair and maintenance costs on jackup rigs that were undergoing shipyard projects during the prior year period. These declines were partially offset by deferred gain amortization on the sale of ENSCO 83, ENSCO 89 and ENSCO 98 during 2015 and higher ENSCO 110 contract drilling expense during the current period.

Jackup depreciation expense for the three-month and nine-month periods ended September 30, 2016 declined $12.7 million , or 28% , and $39.1 million , or 30% , respectively, as compared to the prior year periods due primarily to lower depreciation expense on jackups that were impaired during 2015. The decline in depreciation expense for the nine-month period was partially offset by the addition of ENSCO 110 to the active fleet.

Interest expense for the three-month and nine-month periods ended September 30, 2016 declined as compared to the prior year periods due to the repurchase of $1.1 billion of debt during 2016, partially offset by the impact of higher interest rates on our debt refinanced during 2015. Interest expense capitalized during the three-month and nine-month periods ended September 30, 2016 declined as compared to the prior year periods due to newbuild rigs placed into service during 2015.

Other, net, for the three-month and nine-month periods ended September 30, 2016 included pre-tax gains on debt extinguishment of $18.2 million and $279.0 million , respectively, related to debt repurchases. Other, net, for the nine-month period ended September 30, 2015 included a pre-tax loss on debt extinguishment of $33.5 million related to make-whole premiums on our 2015 debt redemption.

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. 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 $600,000 and $2.4 million , inclusive of offsetting fair value derivatives, were included in other, net, for the three-month and nine-month periods ended September 30, 2016 , respectively. Net foreign currency exchange gains of $4.1 million and $5.6 million , inclusive of offsetting fair value derivatives, were included in other, net, for the three-month and nine-month periods ended September 30, 2015 , respectively. During the three-month period ended September 30, 2015, other, net included net losses of $2.0 million from marketable securities held in our SERP.

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 generally 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 deemed profits or other bases utilized under local tax laws, rather than to 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 profitability levels and changes in tax laws, our annual effective income tax rate may vary substantially from one reporting period to another. In periods of declining profitability, our income tax expense may not decline proportionally with income, which could result in higher effective income tax rates.

49

Our consolidated effective income tax rate for the three-month and nine-month periods ended September 30, 2016 , excluding the impact of discrete tax items, was 6.0% and 21.9% , respectively. Discrete tax items for the three-month and nine-month period ended September 30, 2016 were primarily attributable to the gain on debt extinguishment, changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and other resolutions of prior year tax matters. Discrete tax items for the nine-month period ended September 30, 2016 also resulted from restructuring transactions involving certain of our subsidiaries.
Our consolidated effective income tax rate for the three-month and nine-month periods ended September 30, 2015 excluding the impact of discrete tax items, was 12.6% and 16.4% , respectively. Discrete tax items for the three-month and nine-month periods were primarily attributable to the early termination of the ENSCO DS-4 drilling contract and the recognition of liabilities for unrecognized tax benefits associated with tax positions taken in prior years.

The changes in our consolidated effective tax rate, excluding discrete items, for the three-month and nine-month periods ended September 30, 2016 as compared to the prior year period is primarily attributable to changes in the relative components of our estimated 2016 earnings, excluding discrete items, generated in tax jurisdictions with higher tax rates and the impact of 2016 restructuring transactions involving certain of our subsidiaries.

Discontinued Operations

During the nine-month period ended 2016, we sold ENSCO DS-2, ENSCO 6000 and ENSCO 58 for scrap value resulting in a net pre-tax gain on sale of $1.2 million included in loss from discontinued operations, net, in our condensed consolidated statements of operations.

ENSCO 7500 and ENSCO 90 remain classified as held-for-sale in our September 30, 2016 condensed consolidated balance sheet and are included in discontinued operations.

For the three-month and nine-month period ended September 30, 2015, loss from discontinued operations, net, included pre-tax impairment losses of $25.6 million and $32.8 million , respectively, as a result of declines in the estimated fair values of several held-for-sale rigs, the operating results of ENSCO 93 and ENSCO 58 and stacking costs of uncontracted rigs included in discontinued operations. A discrete tax benefit of $11.9 million was included in loss from discontinued operations, net, in the nine month period ended September 30, 2015.
        
LIQUIDITY AND CAPITAL RESOURCES

We have historically relied on our cash flow from continuing operations to meet liquidity needs and fund the majority of our cash requirements. We periodically rely on the issuance of debt and/or equity securities to supplement our liquidity needs. A substantial portion of our operating cash flow has been invested in the expansion and enhancement of our drilling rig fleet through newbuild construction and upgrade projects and the return of capital to shareholders through dividend payments. We expect that cash flow generated during 2016 will primarily be used to fund capital expenditures and repurchase debt.

On October 1, 2016, we entered into a privately-negotiated exchange agreement whereby we issued 1,822,432 Class A ordinary shares in exchange for $24.5 million principal amount of our 5.75% Senior Notes due 2044. A gain of approximately $9.0 million from the exchange will be recognized during the fourth quarter. Upon settlement of this transaction, the outstanding principal amount of our 5.75% Senior Notes due 2044 declined from $1.025 billion to $1.0 billion.

During the third quarter, we repurchased $188.7 million of our senior notes for $177.3 million on the open market. During the second quarter, we repurchased $940.2 million of our senior notes for $684.8 million through tender offers and open market repurchases.

50

In April 2016, we closed an underwritten public offering of 65,550,000 Class A ordinary shares at $9.25 per share, inclusive of shares purchased under an underwriters' option. We received net proceeds from the offering of $585.5 million .

Our Board of Directors declared a $0.01 per share quarterly cash dividend during each of the first three quarters of 2016. The declaration and amount of future dividends is at the discretion of our Board of Directors. In the future, our Board of Directors may, without advance notice, determine to reduce or suspend our dividend in order to maintain our financial flexibility and best position us for long-term success. When evaluating dividend payment timing and amounts, our Board of Directors considers several factors, including our profitability, liquidity, financial condition, market outlook, reinvestment opportunities and capital requirements.

During the nine-month period ended September 30, 2016 , our primary sources of cash were $1.0 billion generated from operating activities of continuing operations and $585.5 million in proceeds from our April 2016 equity offering. Our primary uses of cash for the same period were $862.4 million for the repurchase of long-term borrowings and $255.5 million for the construction, enhancement and other improvement of our drilling rigs.

During the nine-month period ended September 30, 2015 , our primary source of cash was $1.3 billion generated from operating activities of continuing operations. Our primary use of cash for the same period was $1.4 billion for the construction, enhancement and other improvement of our drilling rigs.

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, 2016 and 2015 were as follows (in millions):

								
 	2016	 	2015	
Cash flow from operating activities of continuing operations	$	994.8		 	$	1,274.6		
Capital expenditures	 		 	 		
New rig construction	$	155.7		 	$	1,132.1		
Rig enhancements	15.6		 	145.0		
Minor upgrades and improvements	84.2		 	168.7		
 	$	255.5		 	$	1,445.8		
    
Excluding the impact of ENSCO DS-9 and ENSCO 8503 lump-sum termination payments of $185.0 million and $20.0 million , respectively, cash flow from operating activities of continuing operations for the nine-month period ending September 30, 2016 declined $484.8 million , or 38% , as compared to the prior year period. The decline primarily resulted from a $1.1 billion decline in net cash receipts from contract drilling services offset by a $559.7 million decline in net cash payments for contract drilling expenses and a $38.0 million decline in cash payments for income taxes.

We currently have three uncontracted rigs under construction, one ultra-deepwater drillship, one premium jackup rig and one ultra-premium harsh environment jackup rig. During the third quarter of 2015, we agreed with the shipyard to delay the delivery of ENSCO DS-10 until the first quarter of 2017. The final ENSCO DS-10 milestone payment is due upon rig delivery. During the first quarter of 2016, we agreed with the shipyard to delay the delivery of ENSCO 123 until the first quarter of 2018.

In August 2016, we accepted delivery of ENSCO 140. As part of our agreement with the shipyard, this rig will be warm stacked in the shipyard at no additional cost to us for up to two years. ENSCO 141 is scheduled for delivery during the fourth quarter.

51

The following table summarizes the cumulative amount of contractual payments made as of September 30, 2016 for our rigs under construction and estimated timing of our remaining contractual payments (in millions):

																					
 	 	Cumulative Paid (1)	 	Remaining 2016	 	2017	 	2018	 	Total (2)	
ENSCO DS-10	 	$	243.1		 	$	2.3		 	$	308.9		 	$	—		 	$	554.3		
ENSCO 123	 	54.8		 	2.7		 	8.0		 	215.3		 	280.8		
ENSCO 141	 	156.8		 	39.0		 	—		 	—		 	195.8		
 	 	$	454.7		 	$	44.0		 	$	316.9		 	$	215.3		 	$	1,030.9		

(1)  	Cumulative paid represents the aggregate amount of contractual payments made from commencement of the construction agreement through September 30, 2016 .	

(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.	

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 2016 to include approximately $ 225.0 million for newbuild construction, approximately $20.0 million for rig enhancement projects and approximately  $105.0 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.

Financing and Capital Resources
 
Equity Transactions

We filed an automatically effective shelf registration statement on Form S-3 with the U.S. Securities and Exchange Commission on January 15, 2015, 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 2018.

In April 2016, we closed an underwritten public offering of 65,550,000 Class A ordinary shares at $9.25 per share, inclusive of shares purchased under an underwriters' option. We received net proceeds from the offering of approximately $585.5 million .

On October 1, 2016, we entered into a privately-negotiated exchange agreement whereby we issued 1,822,432 Class A ordinary shares in exchange for $24.5 million principal amount of our 5.75% Senior Notes due 2044. A gain of approximately $9.0 million from the exchange will be recognized during the fourth quarter. Upon settlement of this transaction, the outstanding principal amount of our 5.75% Senior Notes due 2044 declined from $1.025 billion to $1.0 billion.

52

Tender Offers and Open Market Repurchases

In March 2016, we launched cash tender offers (the "Tender Offers") to repurchase up to $750.0 million aggregate purchase price of our outstanding debt. We received tenders totaling $860.7 million for an aggregate purchase price of $622.3 million . In April, we used cash on-hand to settle the tendered debt.

During the three-month and nine-month period ended September 30, 2016, we repurchased on the open market $188.7 million and $268.2 million of outstanding debt for an aggregate purchase price of $177.3 million and $239.8 million , respectively.

Our Tender Offers and open market repurchases during the nine-month period ended September 30, 2016 were as follows (in millions):

												
 	 	Aggregate Principal Amount Repurchased	 	Aggregate Repurchase Price (1)	 	Discount %	
8.50% Senior Notes due 2019	 	$	60.3		 	$	53.9		 	10.6	%	
6.875% Senior Notes due 2020	 	219.2		 	181.5		 	17.2	%	
4.70% Senior Notes due 2021	 	817.0		 	609		 	25.5	%	
4.50% Senior Notes due 2024	 	1.7		 	.9		 	47.1	%	
5.20% Senior Notes due 2025	 	30.7		 	16.8		 	45.3	%	
Total	 	$	1,128.9		 	$	862.1		 	23.6	%	
		
(1)  	The aggregate repurchase price excludes accrued interest.	
During the three-month and nine-month periods ending September 30, 2016, we recognized pre-tax gains from debt extinguishment of $18.2 million and $279.0 million , respectively, related to the Tender Offers and open market repurchases, net of discounts, premiums, debt issuance costs and transaction costs.

After giving effect to the debt maturities impacted by the Tender Offers and open market repurchases, our next debt maturity is $439.9 million during 2019, followed by $680.8 million , $683.0 million , $623.2 million and $669.3 million during 2020, 2021, 2024 and 2025, respectively.

From time to time, we and our affiliates may repurchase additional outstanding senior notes in the open market, in privately-negotiated transactions, through tender offers, exchange offers or otherwise, or we may redeem senior notes that are able to be redeemed, pursuant to their terms. Any future repurchases, exchanges or redemptions will depend on various factors existing at that time and there can be no assurance as to which, if any, of these alternatives we may choose to pursue. There can be no assurance that an active trading market will exist for our outstanding senior notes following any such transactions. The extent of the trading market will depend upon a number of factors, including the size of the float, the number of holders remaining at such time and the interest in maintaining a market in the notes on the part of securities firms.

Revolving Credit

We have a $2.25 billion senior unsecured revolving credit facility with a syndicate of banks to be used for general corporate purposes with a term expiring on September 30, 2019 (the "Credit Facility"). In October, we extended the maturity of $1.13 billion of the $2.25 billion commitment for one year to September 30, 2020 . All other terms of the Credit Facility are unchanged. Advances under the Credit Facility bear interest at Base Rate or LIBOR plus an applicable margin rate, depending on our credit ratings. We are required to pay a quarterly commitment fee on the undrawn portion of the commitment, which is also based on our credit rating.

In February 2016, Moody’s announced a downgrade of our credit rating to B1, which is below investment grade. Following the downgrade, the applicable margin rates are 0.50% per annum for Base Rate advances and 1.50% per annum for LIBOR advances. Also, our quarterly commitment fee is 0.225% per annum on the undrawn portion of the commitment. 

In July 2016, Standard & Poor's downgraded our credit rating one notch to BBB-, which maintains our investment grade rating with the rating agency. As previous rating actions resulted in the highest applicable margin rate and commitment fees under our Credit Facility, the July downgrade did not impact our applicable margin rate on borrowings or our quarterly commitment fee. We have limited or no access to the commercial paper market as a result of our current credit ratings.

The Credit Facility requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60% . The Credit Facility also contains customary restrictive covenants, including, among others, prohibitions on creating, incurring or assuming certain debt and liens; entering into certain merger arrangements; selling, leasing, transferring or otherwise disposing of all or substantially all of our assets; making a material change in the nature of the business; and entering into certain transactions with affiliates. We have the right, subject to receipt of commitments from new or existing lenders, to increase the commitments under the Credit Facility by an amount not exceeding $500 million and to extend the maturity of the commitments under the Credit Facility by one additional year.

As of September 30, 2016 , we were in compliance in all material respects with our covenants under the Credit Facility. We had no amounts outstanding under the Credit Facility as of September 30, 2016 and December 31, 2015 .

Our access to credit and capital markets depends on the credit ratings assigned to our debt. There can be no assurance that we will be able to maintain our credit ratings, and any additional actual or anticipated downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could limit our available options when accessing credit and capital markets, or when restructuring or refinancing our debt. In addition, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants.

Other Financing

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 repurchase shares up to a maximum of $2.0 billion in the aggregate under the program, but in no case more than 35.0 million shares. As of September 30, 2016 , no shares have been repurchased under the program. The program terminates in May 2018.
    
Other Commitments

As of September 30, 2016 , we were contingently liable for an aggregate amount of $61.3 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, 2016 , we were not 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):

								
 	September 30,
2016	 	December 31,
2015	
Cash and cash equivalents	$	465.4		 	$	121.3		
Short-term investments	$	1,302.0		 	$	1,180.0		
Working capital	$	1,875.5		 	$	1,509.6		
Current ratio	4.2		 	2.9		

We expect to fund our short-term liquidity needs, including contractual obligations and anticipated capital expenditures, as well as working capital requirements, from our cash and cash equivalents, short-term investments, operating cash flows, and, if necessary, funds borrowed under our revolving credit facility.

We expect to fund our long-term liquidity needs, including contractual obligations and anticipated capital expenditures, 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. 

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. dollars, which significantly reduces the portion of our cash flows and assets denominated in foreign currencies. As of September 30, 2016 , we had cash flow hedges outstanding to exchange an aggregate $204.0 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, 2016 , we held derivatives not designated as hedging instruments to exchange an aggregate $144.1 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, 2016 would approximate $17.3 million . Approximately $12.1 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.

55

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 derivative counterparties 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 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 us to make estimates, judgments and assumptions that affect the amounts reported in our condensed 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, 2015 included in our annual report on Form 10-K filed with the SEC on February 24, 2016 . These policies, along with our underlying judgments and assumptions made in their application, have a significant impact on our condensed 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 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, 2015 . During the quarter ended September 30, 2016 , there were no material changes to the judgments, assumptions or policies upon which our critical accounting estimates are based.
    
New Accounting Pronouncements
    
In October 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“Update 2016-16”), which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transaction occurs as opposed to deferring tax consequences and amortizing them into future periods. This update is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. A modified retrospective approach with a cumulative-effect adjustment directly to retained earnings at the beginning of the period of adoption is required. We are currently evaluating the effect that Update 2016-16 will have on our condensed consolidated financial statements and related disclosures.
In August 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-15, Statement of Cash flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("Update 2016-15"), which addresses the cash flow presentation of eight specific cash flow issues including, debt repayment and extinguishment costs, with the objective of reducing the existing diversity in practice. This update is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. We do not anticipate that our adoption of Update 2016-15 will have a material impact on our condensed consolidated financial statements and related disclosures.

56

In March 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("Update 2016-09"), which simplifies several aspects of accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. Transition methods vary for the related amendments. We will apply Update 2016-09 in our Annual Report on Form 10-K for the year ended December 31, 2016. We do not anticipate that our adoption of Update 2016-09 will have a material impact on our condensed consolidated financial statements and related disclosures.

In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification ("Update 2016-02"), which requires an entity to recognize lease assets and lease liabilities on the balance sheet and to disclose key qualitative and quantitative information about the entity's leasing arrangements. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. A modified retrospective approach is required. We are currently evaluating the effect that Update 2016-02 will have on our condensed consolidated financial statements and related disclosures.

During 2015, the Financial Accounting Standards Board issued Accounting Standards Update 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs ("Update 2015-03"), as updated by Update 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcements at June 18, 2015 EITF Meeting ("Update 2015-05"), which require that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts. Debt issuance costs related to line-of-credit arrangements may be presented as an asset regardless of whether there are any outstanding borrowings on the arrangement. We adopted Update 2015-03 and Update 2015-15 on a retrospective basis effective January 1, 2016. Accordingly, all debt issuance costs, except for the balance related to our line-of-credit arrangement, were presented as a deduction from the carrying amount of the related debt liability on our condensed consolidated balance sheet for all periods presented. As a result of retrospective application, we reclassified debt issuance costs of $26.5 million on our condensed consolidated balance sheet as of December 31, 2015. There is no impact to the manner in which debt issuance costs are amortized in our condensed consolidated financial statements.

During 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. In 2015, the Financial Accounting Standards Board voted to delay the effective date one year. Update 2014-09 is now effective for annual and interim periods for fiscal years beginning after December 15, 2017, though companies have an option of adopting the standard for fiscal years beginning after December 15, 2016. During 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ("Update 2016-08"), Accounting Standards Update 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ("Update 2016-10") and Account Standards Update 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ("Update 2016-12"). The amendments in Update 2016-08, 2016-10 and 2016-12 do not change the core principle of Update 2014-09 but instead clarify the implementation guidance on principle versus agent considerations, identifying performance obligations and the licensing implementation guidance, and provide narrow-scope improvements, respectively. Update 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP and may be adopted using a retrospective, modified retrospective or prospective with a cumulative catch-up approach. We are currently evaluating the effect that Update 2014-09 will have on our condensed consolidated financial statements and related disclosures.

PART II - OTHER INFORMATION

Item 1.    Legal Proceedings
 
Brazil Internal Investigation

Pride International, Inc. (“Pride”), a company we acquired in 2011, commenced drilling operations in Brazil in 2001. In 2008, Pride entered into a drilling services agreement with Petrobras (the "DSA") for ENSCO DS-5, a drillship ordered from Samsung Heavy Industries, a shipyard in South Korea ("SHI"). Beginning in 2006, Pride conducted periodic compliance reviews of its business with Petrobras, and, after the acquisition of Pride, Ensco conducted similar compliance reviews, the most recent of which commenced in early 2015 after media reports were released regarding ongoing investigations of various kickback and bribery schemes in Brazil involving Petrobras.

While conducting our compliance review, we became aware of an internal audit report by Petrobras alleging irregularities in relation to the DSA. Upon learning of the Petrobras internal audit report, our Audit Committee appointed independent counsel to lead an investigation into the alleged irregularities. Further, in June and July 2015, we voluntarily contacted the SEC and the DOJ, respectively, to advise them of this matter and our Audit Committee’s investigation. Independent counsel, under the direction of our Audit Committee, has substantially completed its investigation by reviewing and analyzing available documents and correspondence and interviewing current and former employees involved in the DSA negotiations and the negotiation of the ENSCO DS-5 construction contract with SHI (the "DS-5 Construction Contract").

To date, our Audit Committee has found no evidence that Pride or Ensco or any of their current or former employees were aware of or involved in any wrongdoing, and our Audit Committee has found no evidence linking Ensco or Pride to any illegal acts committed by our former marketing consultant, who provided services to Pride and Ensco in connection with the DSA. Independent counsel has continued to provide the SEC and DOJ with updates throughout the investigation, including detailed briefings regarding its investigation and findings. On December 21, 2015, we entered into a one-year tolling agreement with the DOJ. On March 7, 2016, we entered into a one-year tolling agreement with the SEC.

Subsequent to initiating our Audit Committee investigation, Brazilian court documents connected to the prosecution of former Petrobras directors and employees as well as certain other third parties, including our former marketing consultant, referenced the alleged irregularities cited in the Petrobras internal audit report. Our former marketing consultant has entered into a plea agreement with the Brazilian authorities. On January 10, 2016, Brazilian authorities filed an indictment against a former Petrobras director. This indictment states that the former Petrobras director received bribes paid out of proceeds from a brokerage agreement entered into for purposes of intermediating a drillship construction contract between SHI and Pride, which we believe to be the DS-5 Construction Contract. The parties to the brokerage agreement were a company affiliated with a person acting on behalf of the former Petrobras director, a company affiliated with our former marketing consultant, and SHI. The indictment alleges that amounts paid by SHI under the brokerage agreement ultimately were used to pay bribes to the former Petrobras director. The indictment does not state that Pride or Ensco or any of their current or former employees were involved in the bribery scheme or had any knowledge of the bribery scheme.

On January 4, 2016, we received a notice from Petrobras declaring the DSA void effective immediately. Petrobras’ notice alleges that our former marketing consultant both received and procured improper payments from SHI for employees of Petrobras and that Pride had knowledge of this activity and assisted in the procurement of and/or facilitated these improper payments. We disagree with Petrobras’ allegations. See "—DSA Dispute" below for additional information.

59

Outside of Petrobras’ allegations, we have not been contacted by any Brazil governmental authority regarding alleged wrongdoing by Pride or Ensco or any of their current or former employees related to this matter. We cannot predict whether any U.S., Brazilian or other governmental authority will seek to investigate Pride's involvement in this matter, or if a proceeding were opened, the scope or ultimate outcome of any such investigation. If the SEC or DOJ determines that violations of the FCPA have occurred, or if any governmental authority determines that we have violated applicable anti-bribery laws, they could seek civil and criminal sanctions, including monetary penalties, against us, as well as changes to our business practices and compliance programs, any of which could have a material adverse effect on our business and financial condition. Our customers, business partners and other stakeholders could seek to take actions adverse to our interests. Further, investigating and resolving such allegations is expensive and could consume significant management time and attention. Although our internal investigation is substantially complete, we cannot predict whether any additional allegations will be made or whether any additional facts relevant to the investigation will be uncovered during the course of the investigation and what impact those allegations and additional facts will have on the timing or conclusions of the investigation. Our Audit Committee will examine any such additional allegations and additional facts and the circumstances surrounding them.

DSA Dispute

As described above, on January 4, 2016, Petrobras sent a notice to us declaring the DSA void effective immediately, reserving its rights and stating its intention to seek any restitution to which it may be entitled. We disagree with Petrobras’ declaration that the DSA is void. We believe that Petrobras has repudiated the DSA and have therefore accepted the DSA as terminated on April 8, 2016 (the "Termination Date"). At this time, we cannot reasonably determine the validity of Petrobras' claim or the range of our potential exposure, if any. As a result, there can be no assurance as to how this dispute will ultimately be resolved.

We did not recognize revenue for amounts owed to us under the DSA from the beginning of the fourth quarter of 2015 through the Termination Date, as we concluded that collectability of these amounts was not reasonably assured. Additionally, our receivables from Petrobras related to the DSA from prior to the fourth quarter of 2015 are fully reserved in our condensed consolidated balance sheet as of September 30, 2016. We have initiated arbitration proceedings in the U.K. against Petrobras seeking payment of all amounts owed to us under the DSA, in addition to any other amounts to which we are entitled, and intend to vigorously pursue our claims. Petrobras subsequently filed a counterclaim seeking restitution of certain sums paid under the DSA less value received by Petrobras under the DSA. We have also initiated separate arbitration proceedings in the U.K. against SHI for any losses we have incurred in connection with the foregoing. There can be no assurance as to how these arbitration proceedings will ultimately be resolved.

Pride FCPA Investigation

During 2010, Pride and its subsidiaries resolved their previously disclosed investigations into potential violations of the U.S. Foreign Corrupt Practices Act of 1977 (the "FCPA") with the U.S. Department of Justice ("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 certain jurisdictions and the seizure of rigs or other assets. At this stage of such inquiries, we are unable to determine what, if any, legal liability may result. Our customers in certain 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 stakeholders. 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, to attract and retain employees and to access the capital markets.

60

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  43 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  plaintiffs to settle lawsuits filed in Mississippi for a nominal amount. A special master reviewed all  58  cases and made an allocation of settlement funds among the parties.  The District Court Judge reviewed the allocations and accepted the special master’s recommendations and approved the settlements.  The settlement documents for most of the individual plaintiffs have been processed, and the cases dismissed. The settlement documents for approximately 10 individual plaintiffs continue to be processed.

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, brine, chemicals, grease or fuel from drilling rigs operating offshore Brazil from 2008 to 2016, pursuant to which the governmental authorities have assessed, or are anticipated to assess, fines. 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 $180,000 liability related to these matters was included in accrued liabilities and other in our condensed consolidated balance sheet as of September 30, 2016 .
 
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 $3.0 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.

61

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.

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, 2015 , 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. 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, 2015 .

62

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds
 
The table below provides a summary of our repurchases of equity securities during the quarter ended September 30, 2016 :

Total 	22,301		 	$	8.83		 	—		 	 		

(1)  	During the quarter ended September 30, 2016 , 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 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 repurchase up to a maximum of $2.0 billion in the aggregate under the program, but in no case more than 35.0 million shares. As of September 30, 2016 , no shares have been repurchased under the program. The program terminates in May 2018.	

On October 1, 2016, we entered into a privately-negotiated exchange agreement whereby we issued an aggregate of 1,822,432 Class A ordinary shares, representing less than one percent of our outstanding Class A ordinary shares, in exchange for $24.5 million principal amount of our 5.75% Senior Notes due 2044. The issuance of the shares in exchange for our senior notes was made in reliance on the exemption from registration provided in Section 3(a)(9) of the Securities Act.
