Note 2 - Acquisition of Pride International, Inc.

On May 31, 2011 (the "Merger Date"), Ensco plc completed a merger transaction (the "Merger") with Pride International, Inc., a Delaware corporation ("Pride"), ENSCO International Incorporated, a Delaware corporation and an indirect, wholly-owned subsidiary and predecessor of Ensco ("Ensco Delaware"), and ENSCO Ventures LLC, a Delaware limited liability company and an indirect, wholly-owned subsidiary of Ensco plc ("Merger Sub"). Pursuant to the Agreement and Plan of Merger, dated as of February 6, 2011 (as amended, the "Merger Agreement"), among Ensco plc, Pride, Ensco Delaware and Merger Sub, and subject to the conditions set forth therein, Merger Sub merged with and into Pride, with Pride as the surviving entity and an indirect, wholly-owned subsidiary of Ensco plc.

The Merger expands our deepwater fleet with drillship assets, increases our presence in the floater markets as well as various major offshore drilling markets and establishes Ensco with the world's second largest offshore drilling rig fleet. Revenues and net income of Pride from the Merger Date included in our condensed consolidated statements of income were $440.1 million and $62.6 million, respectively, for the three-month period ended September 30, 2011 and $591.3 million and $86.9 million, respectively, for the nine-month period ended September 30, 2011.

Consideration

As a result of the Merger, each outstanding share of Pride's common stock (other than shares of common stock held directly or indirectly by Ensco, Pride or any wholly-owned subsidiary of Ensco or Pride (which were cancelled as a result of the Merger) and those shares held by certain U.K. residents if determined by Ensco) were converted into the right to receive $15.60 in cash and 0.4778 Ensco American depositary shares, each representing one Class A ordinary share ("ADS" or "share"). Under certain circumstances, U.K. residents received all cash consideration as a result of compliance with legal requirements. The total consideration delivered in the Merger was $7.4 billion, consisting of $2.8 billion of cash, 85.8 million Ensco ADSs with an aggregate value of $4.6 billion based on the closing price of Ensco ADSs of $53.32 on the Merger Date and the estimated fair value of $35.4 million of vested Pride employee stock options assumed by Ensco.

The following table summarizes the components of the merger consideration (dollars in millions, except per share amounts):

Share consideration paid:
179.7 million outstanding shares of Pride common stock converted to 85.8 million of Ensco ADSs using the exchange ratio of 0.4778 and valued at $53.32 per share		$4,577.5

Cash and other consideration paid:
179.7 million outstanding shares of Pride common stock at $15.60 per share		2,803.0
Estimated fair value of 2.5 million vested Pride employee stock options assumed by Ensco		35.4
Merger consideration		$7,415.9

Assets Acquired and Liabilities Assumed

The transaction has been accounted for using the acquisition method of accounting which requires that assets acquired and liabilities assumed be recorded at their estimated fair values as of the Merger Date. The excess of the consideration transferred over the estimated fair values of the net assets acquired was recorded as goodwill. We have not finalized the determination of the fair values of the assets acquired and liabilities assumed and, therefore, the fair value estimates set forth below are subject to adjustment during a measurement period not to exceed one year subsequent to the acquisition date as permitted under GAAP. The estimated fair values of certain assets and liabilities, including inventory, taxes and contingencies require judgments and assumptions that increase the likelihood that adjustments may be made to these estimates during the measurement period. The provisional amounts and respective measurement period adjustments recorded for assets acquired and liabilities assumed were based on preliminary estimates of their fair values as of the Merger Date and were as follows:

	Amounts Recognized as of Merger Date	Measurement Period Adjustments(1)	Estimated Fair Value
Assets:
Cash and cash equivalents	$ 147.0	$ --	$ 147.0
Accounts receivable(2)	371.3	--	371.3
Other current assets	150.9	--	150.9
Property and equipment	6,758.8	--	6,758.8
Other assets	343.7	--	343.7
Liabilities:
Accounts payable and accrued liabilities and other	539.8	2.1	541.9
Debt	2,436.0	--	2,436.0
Deferred income tax liabilities	19.0	--	19.0
Other liabilities	319.8	(1.0)	318.8
Net assets acquired	4,457.1	(1.1)	4,456.0
Less merger consideration	7,415.9	--	7,415.9
Goodwill	$2,958.8	$ 1.1	$2,959.9

(1)

The measurement period adjustments reflect changes in the estimated fair values of certain liabilities, including contingencies and income taxes. The measurement period adjustments were recorded to reflect new information obtained about facts and circumstances existing as of the Merger Date and did not result from intervening events subsequent to the Merger Date. These adjustments did not have a material impact on the Company's previously reported results of operations or financial position subsequent to the Merger Date and, therefore, the Company has not retrospectively adjusted its consolidated financial statements.

(2)

Gross contractual amounts receivable totaled $394.7 million as of the Merger Date.

Property and Equipment

Property and equipment acquired in connection with the Merger consisted primarily of drilling rigs and related equipment, including seven drillships (two of which are under construction), 12 semisubmersible rigs and seven jackup rigs. We recorded step-up adjustments in the aggregate of $285.5 million to record the estimated fair value of Pride's drilling rigs and related equipment, which were primarily based on an income approach valuation model. We estimated remaining useful lives for Pride's drilling rigs, which ranged from 10 to 35 years based on original estimated useful lives of 30 to 35 years.

In connection with the integration of Pride's operations, we are in the process of changing the names of most of Pride's fleet in accordance with our naming convention. For purposes of the notes to the condensed consolidated financial statements, we used the new names whether or not the name change had been legally completed.

Goodwill

Goodwill recognized as a result of the Merger was calculated as the excess of the consideration transferred over the net assets acquired and represents the future economic benefits arising from other intangible assets acquired that could not be individually identified and separately recognized. Goodwill specifically includes the expected synergies and other benefits that we believe will result from combining the operations of Pride with the operations of Ensco and other intangible assets that do not qualify for separate recognition, such as assembled workforce in place at the Merger Date. Goodwill is not expected to be tax deductible.

Goodwill recognized as a result of the Merger preliminarily was allocated to our reportable segments as follows (in millions):

Deepwater					$2,486.1
Midwater					473.8
Jackup					--
Total					$2,959.9

Other Intangible Assets and Liabilities

We recorded intangible assets and liabilities in the aggregate of $209.0 million and $276.0 million, respectively, representing the estimated fair values of Pride's firm drilling contracts in place at the Merger Date with favorable or unfavorable contract terms as compared to then current market day rates for comparable drilling rigs. The various factors considered in the determination of these fair values were (1) the contracted day rate for each contract, (2) the remaining term of each contract, (3) the rig class and (4) the market conditions for each respective rig class at the Merger Date. The intangible assets and liabilities were calculated based on the present value of the difference in cash inflows over the remaining contract term as compared to a hypothetical contract with the same remaining term at an estimated then current market day rate using a risk-adjusted discount rate and an estimated effective income tax rate. After amortizing $27.1 million of contract intangible assets and liabilities to operating revenues during the nine-month period ended September 30, 2011, the remaining balances were $186.2 million of intangible assets included in other current assets and other assets, net, and $226.1 million of intangible liabilities included in accrued liabilities and other and other liabilities on our condensed consolidated balance sheet as of September 30, 2011. These balances will be amortized to operating revenues over the respective remaining drilling contract terms on a straight-line basis. Amortization income (expense) for these intangible assets and liabilities is estimated to be $26.8 million for the remainder of 2011, $26.0 million for 2012, $7.9 million for 2013, ($4.8) million for 2014, ($15.6) million for 2015 and ($400,000) thereafter.

We recorded an intangible liability of $36.0 million for the estimated fair value of an unfavorable drillship construction contract which was determined by comparing the firm obligations for the remaining construction of the ENSCO DS-6 as of May 31, 2011 to then current market rates for the construction of a similar design drilling rig. The unfavorable construction contract liability was calculated based on the present value of the difference in cash outflows for the remaining contractual payments as compared to a hypothetical contract with the same remaining contractual payments at then current market rates using a risk-adjusted discount rate and estimated effective income tax rate. This liability will be amortized over the estimated useful life of ENSCO DS-6 as a reduction of depreciation expense beginning on the date the rig is placed into service.

Debt

We assumed Pride's outstanding debt comprised of $900.0 million aggregate principal amount of 6.875% senior notes due 2020, $500.0 million aggregate principal amount of 8.500% senior notes due 2019, $300.0 million aggregate principal amount of 7.875% senior notes due 2040 (collectively the "Pride Notes") and $151.5 million aggregate principal amount of Maritime Administration ("MARAD") bonds due 2016. Under a supplemental indenture, Ensco plc has fully and unconditionally guaranteed the performance of all obligations of Pride with respect to the Pride Notes. See "Note 17 - Guarantee of Registered Securities" for additional information on the guarantee of the Pride Notes. A step-up adjustment of $406.2 million was recorded to adjust the Pride Notes and the MARAD bonds to their aggregate estimated fair value. The adjustment was based on quoted market prices for Pride's publicly traded debt and an income approach valuation model for Pride's non-publicly traded debt. In addition, we assumed debt outstanding with respect to Pride's senior unsecured revolving credit facility totaling $181.0 million, which was repaid in full and the facility terminated upon completion of the Merger.

Merger-Related Costs

Merger-related transaction costs consisted of various advisory, legal, accounting, valuation and other professional or consulting fees totaling $23.8 million for the nine-month period ended September 30, 2011 and were expensed as incurred and included in general and administrative expense on our condensed consolidated statement of income. Debt issuance costs of $27.2 million associated with our senior notes issued in March 2011 and bridge term facility issued in February 2011 were deferred and are amortized to interest expense over the lives of the respective debt arrangements. The costs of $70.5 million associated with the Ensco ADSs issued to effect the Merger were recorded as a reduction to additional paid-in capital.

Deferred Taxes

The acquisition of a business through the purchase of its common stock generally is treated as a "nontaxable" transaction. The acquisition of Pride was executed through the acquisition of its outstanding common stock and, therefore, the historical tax bases of the acquired assets and assumed liabilities, net operating losses and other tax attributes of Pride were assumed as of the Merger Date. However, adjustments were recorded to recognize deferred tax assets and liabilities for the tax effects of differences between acquisition date fair values and tax bases of assets acquired and liabilities assumed. As of the Merger Date, a decrease of $24.2 million to Pride's net deferred tax liability was recognized.

Deferred tax assets and liabilities recognized in connection with the Merger were measured at rates enacted as of the Merger Date. Tax rate changes, or any deferred tax adjustments for new tax legislation, following the Merger Date will be reflected in our operating results in the period in which the change in tax laws or rate is enacted.

Contingencies

In connection with the Merger, we recognized contingent liabilities resulting from certain lawsuits, claims or proceedings existing as of the Merger Date. These matters existed as of the Merger Date as Pride was involved from time to time as party to governmental or other 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. See "Note 14 – Contingencies" for additional information on contingencies.

Pro Forma Impact of the Merger

The following unaudited supplemental pro forma results present consolidated information as if the Merger had been completed on January 1, 2010. The pro forma results include, among others, (i) the amortization associated with the acquired intangible assets and liabilities, (ii) interest expense associated with debt used to fund a portion of the Merger and (iii) the impact of certain fair value adjustments such as additional depreciation expense for adjustments to property and equipment and reduction to interest expense for adjustments to debt. The pro forma results do not include any potential synergies, non-recurring charges which result directly from the Merger, cost savings or other expected benefits of the Merger. Accordingly, the pro forma results should not be considered indicative of the results that would have occurred if the Merger and related borrowings had occurred on January 1, 2010, nor are they indicative of future results.


(In millions, except per share amounts)	Three Months Ended		Nine Months Ended
	September 30,		September 30,
	2011(1)	2010	2011	2010

Revenues	$898.0	$791.9	$2,531.2	$2,410.0
Net income	189.4	172.8	401.6	629.8
Earnings per share - basic	0.81	0.75	1.73	2.73
Earnings per share - diluted	0.81	0.75	1.73	2.73

(1)

Our actual results and our pro forma results differ for the quarter ended September 30, 2011 due to the fact the pro forma results assume the acquisition of Pride occurred on January 1, 2010, resulting in differing amortization periods associated with acquired drilling contract intangible assets and liabilities.
