This combined Quarterly Report on Form 10-Q is separately filed by Noble Corporation, a Swiss corporation (“Noble-Swiss”), and Noble Corporation, a Cayman Islands company (“Noble-Cayman”). Information in this filing relating to Noble-Cayman is filed by Noble-Swiss and separately by Noble-Cayman on its own behalf. Noble-Cayman makes no representation as to information relating to Noble-Swiss (except as it may relate to Noble-Cayman) or any other affiliate or subsidiary of Noble-Swiss. Since Noble-Cayman meets the conditions specified in General Instructions H(1)(a) and (b) to Form 10-Q, it is permitted to use the reduced disclosure format for wholly owned subsidiaries of reporting companies. Accordingly, Noble-Cayman has omitted from this report the information called for by Item 3 (Quantitative and Qualitative Disclosures about Market Risk) of Part I of Form 10-Q and the following items of Part II of Form 10-Q: Item 2 (Unregistered Sales of Equity Securities and Use of Proceeds) and Item 3 (Defaults upon Senior Securities).

This report should be read in its entirety as it pertains to each Registrant. Except where indicated, the Consolidated Financial Statements and related Notes are combined. References in this Quarterly Report on Form 10-Q to “Noble,” the “Company,” “we,” “us,” “our” and words of similar meaning refer collectively to Noble-Swiss and its consolidated subsidiaries, including Noble-Cayman.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share data)

Note 1 — Organization and Basis of Presentation

Noble Corporation, a Swiss corporation, is a leading offshore drilling contractor for the oil and gas industry. At September 30, 2011, our fleet consisted of 79 mobile offshore drilling units located worldwide as follows: 14 semisubmersibles, 14 drillships, 49 jackups and two submersibles. Additionally, we have one floating production storage and offloading unit (“FPSO”). At September 30, 2011, we had 13 units under construction as follows:

•

seven dynamically positioned, ultra-deepwater, harsh environment drillships, including two Globetrotter-class drillships and one Bully-class drillship, and

•

six high-specification heavy duty, harsh environment jackup rigs.

Our global fleet is currently located in the following areas: the Middle East, India, the U.S. Gulf of Mexico, Mexico, the Mediterranean, the North Sea, Brazil, West Africa and the Asian Pacific. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921.

Noble-Cayman is a direct, wholly-owned subsidiary of Noble-Swiss, our publicly-traded parent company. Noble-Swiss’ principal asset is all of the shares of Noble-Cayman. Noble-Cayman has no public equity outstanding. The consolidated financial statements of Noble-Swiss include the accounts of Noble-Cayman, and Noble-Swiss conducts substantially all of its business through Noble-Cayman and its subsidiaries.

The accompanying unaudited consolidated financial statements of Noble-Swiss and Noble-Cayman have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) as they pertain to Form 10-Q. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the financial position and results of operations for the interim periods, on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a normal recurring nature. The December 31, 2010 Consolidated Balance Sheets presented herein are derived from the December 31, 2010 audited consolidated financial statements. These interim financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2010, filed by both Noble-Swiss and Noble-Cayman. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.

Certain amounts in prior periods have been reclassified to conform to the current year presentation. Taxes payable in the December 31, 2010 Consolidated Balance Sheets was reported net of approximately $81 million in taxes receivable. During the second quarter of 2011, we determined that a right of offset in certain taxable jurisdictions did not exist for these receivables, and they are now being disclosed separately as a current asset. For the December 31, 2010 Consolidated Balance Sheets presented herein, these amounts have been reclassified to conform to the current year presentation. We believe that this reclassification is immaterial, as it did not have a material impact on our financial position, working capital, results of operations or cash flows from operations.

Note 2 — Acquisition of FDR Holdings Limited

On July 28, 2010, Noble-Swiss and Noble AM Merger Co., a Cayman Islands company and indirect wholly-owned subsidiary of Noble-Swiss (“Merger Sub”), completed the acquisition of FDR Holdings Limited, a Cayman Islands company (“Frontier”). Under the terms of the Agreement and Plan of Merger with Frontier and certain of Frontier’s shareholders, Merger Sub merged with and into Frontier, with Frontier surviving as an indirect wholly-owned subsidiary of Noble-Swiss and a wholly-owned subsidiary of Noble-Cayman. The Frontier acquisition was for a purchase price of approximately $1.7 billion in cash plus liabilities assumed and strategically expanded and enhanced our global fleet. Frontier’s results of operations were included in our results beginning July 28, 2010. We funded the cash consideration paid at closing of approximately $1.7 billion using proceeds from our July 2010 offering of senior notes and existing cash on hand.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The following unaudited pro forma financial information for the three and nine months ended September 30, 2010 gives effect to the Frontier acquisition as if it had occurred at January 1, 2009. The pro forma results are based on historical data and are not intended to be indicative of the results of future operations.

Note 3 — Consolidated Joint Ventures

In connection with the Frontier acquisition, we acquired Frontier’s 50 percent interest in two joint ventures, each with a subsidiary of Royal Dutch Shell, PLC (“Shell”), for the construction and operation of the two Bully-class drillships. Since these entities’ equity at risk is insufficient to permit them to carry on their activities without additional financial support, they each meet the criteria for a variable interest entity. We have determined that we are the primary beneficiary for accounting purposes. Accordingly, we consolidate the entities in our consolidated financial statements after eliminating intercompany transactions. Shell’s equity interests are presented as noncontrolling interests on our Consolidated Balance Sheets.

In the first quarter of 2011, the joint venture credit facilities, which had a combined outstanding balance of $693 million, were repaid in full through contributions to the joint ventures from Noble and Shell. Shell contributed $361 million in equity to fund their portion of the repayment of joint venture credit facilities and related interest rate swaps, which were settled concurrent with the repayment and termination of the joint venture credit facilities.

In January 2011, the Bully joint ventures issued notes to the joint venture partners totaling $70 million. The interest rate on these notes was 10%, payable semi-annually in arrears and in kind on June 30 and December 31 commencing in June 2011. The purpose of these notes was to provide additional liquidity to the joint ventures in connection with the shipyard construction of the Bully vessels.

In April 2011, the Bully joint venture partners entered into a subscription agreement, pursuant to which each partner was issued equity in each of the Bully joint ventures in exchange for the cancellation of all outstanding joint venture partner notes. The subscription agreement converted all joint venture partner notes into equity of the respective joint venture. The total capital contributed as a result of these agreements was $146 million, which included $142 million in outstanding notes, plus accrued interest. Our portion of the capital contribution, totaling $73 million, was eliminated in consolidation.

In April 2011, the Bully joint venture partners also entered into capital contribution agreements whereby capital calls up to a total of $360 million can be made for funds needed to complete the projects. As of September 30, 2011, the total capital contributed under these agreements was $170 million. Subsequent to the third quarter, an additional $60 million of capital was contributed under these agreements.

At September 30, 2011, the combined carrying amount of the drillships was $1.3 billion, which was primarily funded through partner equity contributions.

Note 4 — Share Data

Share capital

The following is a detail of Noble-Swiss’ share capital as of September 30, 2011 and December 31, 2010:


	September 30,		December 31,
	2011		2010

Shares outstanding and trading		252,433		252,275
Treasury shares		285		10,140

Total shares outstanding		252,718		262,415
Treasury shares held for share-based compensation plans		13,432		13,851

Total shares authorized for issuance		266,150		276,266

Par value per share (in Swiss Francs)		3.54		3.93

Shares authorized for issuance by Noble-Swiss at September 30, 2011 totaled 266.2 million shares and include 0.3 million shares held in treasury and 13.4 million treasury shares held by a wholly-owned subsidiary. Repurchased treasury shares are recorded at cost, and include shares repurchased pursuant to our approved share repurchase program discussed below and shares surrendered by employees for taxes payable upon the vesting of restricted stock.

Share repurchases are made pursuant to the share repurchase program that our Board of Directors authorized and adopted. All shares repurchased under our share repurchase program are held in treasury. The number of shares that we may hold in treasury is limited under Swiss law. At September 30, 2011, 6.8 million shares remained available for repurchase under previous authorization by the Board of Directors. No shares have been repurchased under this authorization during the nine months ended September 30, 2011.

During July 2011, after making the required filings with the Swiss Commercial Register, 10.1 million repurchased shares held in treasury were cancelled and the total number of shares authorized for issuance was reduced to 266.2 million shares.

Our Board of Directors may further increase Noble-Swiss’ share capital through the issuance of up to 138.1 million conditionally authorized registered shares without obtaining shareholder approval. The issuance of these conditionally authorized registered shares is subject to certain conditions regarding their use.

Earnings per share

The following table sets forth the computation of basic and diluted earnings per share for Noble-Swiss:


	Three months ended						Nine months ended
	September 30,						September 30,
	2011			2010			2011			2010
Allocation of net income

Only those items having a dilutive impact on our basic earnings per share are included in diluted earnings per share. At September 30, 2011, stock options totaling approximately 1.1 million were excluded from the diluted earnings per share as they were not dilutive as compared to 0.8 million at September 30, 2010.

Note 5 — Property and Equipment

Property and equipment, at cost, as of September 30, 2011 and December 31, 2010 consisted of the following:


	2011		2010
Drilling equipment and facilities	$	9,908,049	$	8,900,266
Construction in progress		4,318,705		3,571,017
Other		193,513		172,583

	$	14,420,267	$	12,643,866

Capital expenditures, including capitalized interest, totaled $2.0 billion and $886 million for the nine months ended September 30, 2011 and 2010, respectively. Capital expenditures for 2010 do not include the fair value of assets acquired as part of the Frontier acquisition. Capital expenditures for 2011 consisted of the following:

•

$1.3 billion for newbuild construction;

•

$463 million for major projects, including $130 million to upgrade two drillships currently operating in Brazil;

•

$156 million for other capitalized expenditures, including major maintenance and regulatory expenditures which generally have useful lives ranging from 3 to 5 years; and

•

$88 million in capitalized interest.

Interest is capitalized on construction-in-progress at the weighted average cost of debt outstanding during the period of construction. Capitalized interest was $32 million and $88 million for the three and nine months ended September 30, 2011, respectively, as compared to $25 million and $51 million for the three and nine months ended September 30, 2010, respectively.

Note 6 — Gain on contract extinguishments, net

In January 2011, we announced the signing of a Memorandum of Understanding (“MOU”) with Petroleo Brasileiro S.A. (“Petrobras”) regarding operations in Brazil. Under the terms of the MOU, we agreed to substitute the Noble Phoenix, then under contract with Shell in Southeast Asia, for the Noble Muravlenko. In January 2011, Shell agreed to release the Noble Phoenix from its contract, which was effective in March 2011. During the second quarter of 2011, Petrobras formally approved the rig substitution. We expect that acceptance of the Noble Phoenix will take place in the first quarter of 2012. In connection with the cancelation of the contract with Shell on the Noble Phoenix, we recognized a non-cash gain of approximately $52.5 million during the first quarter of 2011, which represented the unamortized fair value of the in-place contract assumed in connection with the Frontier acquisition.

Also in January 2011, as a result of the substitution discussed above, we reached a decision not to proceed with the previously announced reliability upgrade to the Noble Muravlenko that was scheduled to take place in 2013. As a result, we incurred a non-cash charge of approximately $32.6 million related to the termination of outstanding shipyard contracts.

In February 2011, the outstanding balances of the Bully joint venture credit facilities, which totaled $693 million, were repaid in full and the credit facilities terminated using a portion of the proceeds from our February 2011 debt offering and equity contributions from our joint venture partner. In addition, the related interest rate swaps were settled and terminated concurrent with the repayment and termination of the credit facilities. As a result of these transactions, we recognized a gain of approximately $1.3 million during the first quarter of 2011.

Note 7 — Receivables from Customers

As noted in Note 13, in May 2010 Anadarko Petroleum Corporation (“Anadarko”) sent a letter asserting that the initial attempted deepwater drilling moratorium in the U.S. Gulf of Mexico was an event of force majeure under the drilling contract for the Noble Amos Runner. In June 2010, Anadarko filed a declaratory judgment action in Federal District Court in Houston, Texas seeking to have the court declare that a force majeure condition had occurred and that the drilling contract was terminated by virtue of the initial proclaimed moratorium. We disagree that a force majeure event occurred and that Anadarko had the right to terminate the contract. In August 2010, we filed a counterclaim seeking damages from Anadarko for breach of contract. Anadarko has also attempted to offset revenue that we had billed for services performed prior to their termination of the contract. At September 30, 2011, we had accounts receivable of approximately $13 million related to this attempted offset. We do not believe Anadarko has a basis to offset these invoiced amounts. While we will continue to litigate the matter to full resolution, we can make no assurances as to the outcome of this dispute.

In June 2010, a subsidiary of Frontier entered into a charter contract with a subsidiary of BP PLC (“BP”) for the Seillean with a term of a minimum of 100 days. The unit went on hire on July 23, 2010. In October 2010, BP initiated an arbitration proceeding against us claiming the contract was void ab initio, or never existed, due to a fundamental breach and has made other claims and is demanding that we reimburse the amounts already paid to us under the charter. We believe BP owes us the amounts due under the charter. The charter contains a “hell or high water” provision requiring payment, and we believe we have satisfied our obligations under the charter. Outstanding receivables related to this charter totaled $35 million as of September 30, 2011. We believe that if BP were to be successful in claiming the contract void ab initio, we would have an indemnity claim against the former shareholders of Frontier. We have put the former owners of Frontier on notice of this potential claim. We can make no assurances as to the outcome of this dispute.

At September 30, 2011, we had accounts receivable of approximately $14 million related to the Noble Max Smith which are being disputed by our customer, Pemex Exploracion y Produccion (“Pemex”). The disputed amount relates to lost revenues due from Pemex for downtime that occurred when our rig was damaged after one of Pemex’s supply boats collided with our rig. While we believe we are entitled to the disputed amounts, we can make no assurances as to the outcome of this dispute.

Note 8 — Debt

Total debt consisted of the following at September 30, 2011 and December 31, 2010:


	September 30,		December 31,
	2011		2010
Wholly-owned debt instruments:

Joint venture partner notes		—		35,972

Total Debt		3,811,866		2,766,697
Less: Current Maturities		—		(80,213	)

Long-term Debt	$	3,811,866	$	2,686,484

We have two separate revolving credit facilities in place which provide us with a total borrowing capacity of $1.2 billion. One credit facility, which has a capacity of $600 million, matures in 2013, and during the first quarter of 2011, we entered into an additional $600 million revolving credit facility which matures in 2015 (together referred to as the “Credit Facilities”). The covenants and events of default under the Credit Facilities are substantially similar, and each facility contains a covenant that limits our ratio of debt to total tangible capitalization, as defined in the Credit Facilities, to 0.60. We were in compliance with all covenants as of September 30, 2011.

In February 2011, we issued through our indirect wholly-owned subsidiary, Noble Holding International Limited (“NHIL”), $1.1 billion aggregate principal amount of senior notes in three separate tranches, comprising $300 million of 3.05% Senior Notes due 2016, $400 million of 4.625% Senior Notes due 2021, and $400 million of 6.05% Senior Notes due 2041. A portion of the net proceeds of approximately $1.09 billion, after expenses, was used to repay the outstanding balance on our revolving credit facility and to repay our portion of outstanding debt under the joint venture credit facilities discussed below.

In January 2011, the Bully joint ventures issued notes to the joint venture partners totaling $70 million. The interest rate on these notes was 10%, payable semi-annually in arrears, and in kind, on June 30 and December 31 commencing in June 2011. The purpose of these notes was to provide additional liquidity to the joint ventures in connection with the shipyard construction of the Bully vessels.

In April 2011, the Bully joint venture partners entered into a subscription agreement, pursuant to which each partner was issued equity in each of the Bully joint ventures in exchange for the cancellation of all outstanding joint venture partner notes. The subscription agreement has the effect of converting all joint venture partner notes into equity of the respective joint venture. The total capital contributed as a result of these agreements was $146 million, which included $142 million in outstanding notes, plus accrued interest. Our portion of the capital contribution, totaling $73 million, was eliminated in consolidation.

Fair Value of Debt

Fair value represents the amount at which an instrument could be exchanged in a current transaction between willing parties. The estimated fair value of our senior notes was based on the quoted market prices for similar issues or on the current rates offered to us for debt of similar remaining maturities. The following table presents the estimated fair value of our long-term debt as of September 30, 2011 and December 31, 2010.

Note 9 — Income Taxes

At December 31, 2010, the reserves for uncertain tax positions totaled $145 million (net of related tax benefits of $8 million). At September 30, 2011, the reserves for uncertain tax positions totaled $122 million (net of related tax benefits of $8 million). If the September 30, 2011 reserves are not realized, the provision for income taxes would be reduced by $122 million.

It is possible that our existing liabilities related to our reserve for uncertain tax position amounts may increase or decrease in the next twelve months primarily from the completion of open audits or the expiration of statutes of limitation. However, we cannot reasonably estimate a range of changes in our existing liabilities for various uncertainties, such as the unresolved nature of various audits.

During the nine months ended September 30, 2011 and 2010, we made contributions to our pension plans totaling $7 million and $15 million, respectively. We expect the funding to our non-U.S. and U.S. plans in 2011, subject to applicable law, to be approximately $11 million.

We sponsor the Noble Drilling Corporation 401(k) Savings Restoration Plan (“Restoration Plan”). The Restoration Plan is a nonqualified, unfunded employee benefit plan under which certain highly compensated employees may elect to defer compensation in excess of amounts deferrable under our 401(k) savings plan. The Restoration Plan has no assets, and amounts withheld for the Restoration Plan are kept by us for general corporate purposes. The investments selected by employees and the associated returns are tracked on a phantom basis. Accordingly, we have a liability to employees for amounts originally withheld plus phantom investment income or less phantom investment losses. We are at risk for phantom investment income and, conversely, we benefit should phantom investment losses occur. At September 30, 2011 and December 31, 2010, our liability under the Restoration Plan totaled $5 million and $7 million, respectively. We have purchased investments that closely correlate to the investment elections made by participants in the Restoration Plan in order to mitigate the impact of the phantom investment income and losses on our financial statements. The value of these investments held for our benefit totaled $4 million and $7 million at September 30, 2011 and December 31, 2010, respectively.

Note 11 — Derivative Instruments and Hedging Activities

We periodically enter into derivative instruments to manage our exposure to fluctuations in interest rates and foreign currency exchange rates. We have documented policies and procedures to monitor and control the use of derivative instruments. We do not engage in derivative transactions for speculative or trading purposes, nor are we a party to leveraged derivatives. During the period, we maintained certain foreign currency forward contracts that did not qualify under the Financial Accounting Standards Board (“FASB”) standards for hedge accounting treatment and therefore, changes in fair values were recognized as either income or loss in our consolidated income statement.

For foreign currency forward contracts, hedge effectiveness is evaluated at inception based on the matching of critical terms between derivative contracts and the hedged item. For interest rate swaps, we evaluate all material terms between the swap and the underlying debt obligation, known in FASB standards as the “long-haul method.” Any change in fair value resulting from ineffectiveness is recognized immediately in earnings.

Cash Flow Hedges

Our North Sea and Brazil operations have a significant amount of their cash operating expenses payable in local currencies. To limit the potential risk of currency fluctuations, we typically maintain short-term forward contracts settling monthly in their respective local currencies. The forward contract settlements in the remainder of 2011 represent approximately 43 percent of these forecasted local currency requirements. The notional amount of the forward contracts outstanding, expressed in U.S. Dollars, was approximately $71 million at September 30, 2011. Total unrealized losses related to these forward contracts were $6 million as of September 30, 2011 and were recorded as part of “Accumulated other comprehensive loss” (“AOCL”).

Our two joint ventures had maintained interest rate swaps which were classified as cash flow hedges. The purpose of these hedges was to satisfy bank covenants of the then outstanding credit facilities and to limit exposure to changes in interest rates. In February 2011, the outstanding balances of the joint venture credit facilities and the related interest rate swaps were settled and terminated. As a result of these transactions we recognized a gain of $1 million during the nine months ended September 30, 2011.

The balance of the net unrealized gain/(loss) related to our cash flow hedges included in AOCL and related activity is as follows:


	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2011			2010			2011			2010

Net unrealized gain/(loss) at end of period	$	(5,537	)	$	(5,341	)	$	(5,537	)	$	(5,341	)

Fair Value Hedges

We entered into a firm commitment for the construction of the Noble Globetrotter I drillship. The drillship was constructed in two phases, with the second phase being installation and commissioning of the topside equipment. The contract for this second phase of construction was denominated in Euros, and in order to mitigate the risk of fluctuations in foreign currency exchange rates, we entered into forward contracts to purchase Euros. As of September 30, 2011, all amounts related to the forward contracts have settled. We accounted for the forward contracts as fair value hedges, and their fair market value was included in “Other current assets/liabilities” in the Consolidated Balance Sheets. No gain or loss was recognized in the income statement for the three and nine months ended September 30, 2011 or 2010.

Foreign Currency Forward Contracts

One of our joint ventures maintained foreign currency forward contracts to help mitigate the risk of currency fluctuation of the Singapore Dollar for the construction of the Noble Bully II drillship. These contracts were not designated for hedge accounting treatment under FASB standards, and therefore, changes in fair values were recognized as either income or loss in our Consolidated Income Statement. These contracts are referred to as non-designated derivatives in the tables to follow, and all were settled during the first quarter of 2011. For the nine months ended September 30, 2011, we recognized a loss of $0.5 million related to these foreign currency forward contracts.

The derivative instruments have been valued using actively quoted prices and quotes obtained from the counterparties to the derivative instruments. Our cash and cash equivalents, accounts receivable and accounts payable are by their nature short-term. As a result, the carrying values included in the accompanying Consolidated Balance Sheets approximate fair value.

Note 13 — Commitments and Contingencies

As noted in Note 7, in May 2010 Anadarko sent a letter asserting that the initial attempted deepwater drilling moratorium in the U.S. Gulf of Mexico was an event of force majeure under the drilling contract for the Noble Amos Runner. In June 2010, Anadarko filed a declaratory judgment action in Federal District Court in Houston, Texas seeking to have the court declare that a force majeure condition had occurred and that the drilling contract was terminated by virtue of the initial proclaimed moratorium. We disagree that a force majeure event occurred and that Anadarko had the right to terminate the contract. In August 2010, we filed a counterclaim seeking damages from Anadarko for breach of contract. Anadarko has also attempted to offset approximately $13 million that we had billed for services performed prior to their termination of the contract. We do not believe Anadarko has a basis to offset these invoiced amounts. As a result of the uncertainties noted above, we have not recognized any revenue under the portion of this contract relating to the period after termination and the matter could have a material positive effect on our results of operations or cash flows for the period in which the matter is resolved should the court ultimately rule in our favor.

The Noble Homer Ferrington is under contract with a subsidiary of ExxonMobil Corporation (“ExxonMobil”), who entered into an assignment agreement with BP for a two well farm-out of the rig in Libya after successfully drilling two wells with the rig for ExxonMobil. In August 2010, BP attempted to terminate the assignment agreement claiming that the rig was not in the required condition. ExxonMobil has informed us that we must look to BP for payment of the dayrate during the assignment period. In August 2010, we initiated arbitration proceedings under the drilling contract against both BP and ExxonMobil. We do not believe BP had the right to terminate the assignment agreement and believe the rig continued to be fully ready to operate under the drilling contract. The rig has been operating under farm-out arrangements since March 2011. We believe we are owed dayrate by either or both of these clients. The operating dayrate was approximately $538,000 per day for the work in Libya. We are proceeding with the arbitration process and intend to vigorously pursue these claims. As a result of the uncertainties noted above, we have not recognized any revenue during the assignment period and the matter could have a material positive effect on our results of operations or cash flows in the period the matter is resolved should the arbitration panel ultimately rule in our favor.

In August 2007, we entered into a drilling contract with Marathon Oil Company (“Marathon”) for the Noble Jim Day to operate in the U.S. Gulf of Mexico. On January 1, 2011, Marathon provided notice that it was terminating the contract. Marathon’s stated reason for the termination was that the rig had not been accepted by Marathon by December 31, 2010, and Marathon also maintained that a force majeure condition existed under the contract. The contract contained a provision allowing Marathon to terminate if the rig had not commenced operations by December 31, 2010. We believe the rig was ready to commence operations and should have been accepted by Marathon. The contract term was for four years and represented approximately $752 million in contract backlog at the time of termination. No revenue has been recognized under this contract. In March 2011, we filed suit in Texas State District Court against Marathon seeking damages for its actions, and the suit is proceeding. We cannot provide assurance as to the outcome of this lawsuit.

During the fourth quarter of 2007, our Nigerian subsidiary received letters from the Nigerian Maritime Administration and Safety Agency (“NIMASA”) seeking to collect a two percent surcharge on contract amounts under contracts performed by “vessels,” within the meaning of Nigeria’s cabotage laws, engaged in the Nigerian coastal shipping trade. Although we do not believe that these laws apply to our ownership of drilling units, NIMASA is seeking to apply a provision of the Nigerian cabotage laws (which became effective on May 1, 2004) to our offshore drilling units by considering these units to be “vessels” within the meaning of those laws and therefore subject to the surcharge, which is imposed only upon “vessels.” Our offshore drilling units are not engaged in the Nigerian coastal shipping trade and are not in our view “vessels” within the meaning of Nigeria’s cabotage laws. In January 2008, we filed an originating summons against NIMASA and the Minister of Transportation in the Federal High Court of Lagos, Nigeria seeking, among other things, a declaration that our drilling operations do not constitute “coastal trade” or “cabotage” within the meaning of Nigeria’s cabotage laws and that our offshore drilling units are not “vessels” within the meaning of those laws. In February 2009, NIMASA filed suit against us in the Federal High Court of Nigeria seeking collection of the cabotage surcharge. In August 2009, the court issued a favorable ruling in response to our originating summons stating that drilling operations do not fall within the cabotage laws and that drilling rigs are not vessels for purposes of those laws. The court also issued an injunction against the defendants prohibiting their interference with our drilling rigs or drilling operations. NIMASA has appealed the court’s ruling, although the court dismissed NIMASA’s lawsuit filed against us in February 2009. We intend to take all further appropriate legal action to resist the application of Nigeria’s cabotage laws to our drilling units. The outcome of any such legal action and the extent to which we may ultimately be responsible for the surcharge is uncertain. If it is ultimately determined that offshore drilling units constitute vessels within the meaning of the Nigerian cabotage laws, we may be required to pay the surcharge and comply with other aspects of the Nigerian cabotage laws, which could adversely affect our operations in Nigerian waters and require us to incur additional costs of compliance.

NIMASA had also informed the Nigerian Content Division of its position that we are not in compliance with the cabotage laws. The Nigerian Content Division makes determinations of companies’ compliance with applicable local content regulations for purposes of government contracting, including contracting for services in connection with oil and gas concessions where the Nigerian national oil company is a partner. The Nigerian Content Division had originally barred us from participating in new tenders as a result of NIMASA’s allegations, although the Division reversed its actions based on the favorable Federal High Court ruling. However, no assurance can be given with respect to our ability to bid for future work in Nigeria until our dispute with NIMASA is resolved. Further, we continue to evaluate the local content regulations in Nigeria, which could also affect our ability to operate there and our profitability earned from Nigeria.

In November 2010, we concluded our contract for the Noble Duchess in Nigeria. Following the contract, we commenced the exportation process for the rig. The Nigerian Customs Service delayed departure of the rig while we discussed certain spare items that they claimed were unaccounted for and for which duty would be due. We resolved this matter for an immaterial amount and exported the rig during the third quarter of 2011.

We are from time to time a party to various lawsuits that are incidental to our operations in which the claimants seek an unspecified amount of monetary damages for personal injury, including injuries purportedly resulting from exposure to asbestos on drilling rigs and associated facilities. At September 30, 2011, there were approximately 22 asbestos related lawsuits in which we are one of many defendants. These lawsuits have been filed in the United States in the states of Louisiana, Mississippi and Texas. We intend to vigorously defend against the litigation. We do not believe the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows.

We are a defendant in certain claims and litigation arising out of operations in the ordinary course of business, including certain disputes with customers over receivables discussed in Note 7, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations or cash flows. There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims.

We operate in a number of countries throughout the world and our income tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. Our 2008 tax return is currently under audit by the U.S. Internal Revenue Service. In addition, a U.S. subsidiary of Frontier is also under audit for its 2007 and 2008 tax returns. Furthermore, we are currently contesting several non-U.S. tax assessments and may contest future assessments when we believe the assessments are in error. We cannot predict or provide assurance as to the ultimate outcome of the existing or future assessments. We believe the ultimate resolution of the outstanding assessments, for which we have not made any accrual, will not have a material adverse effect on our consolidated financial statements. We recognize uncertain tax positions that we believe have a greater than 50 percent likelihood of being sustained.

Certain of our non-U.S. income tax returns have been examined for the 2002 through 2008 periods and audit claims have been assessed for approximately $286 million (including interest and penalties), primarily in Mexico. We do not believe we owe these amounts and are defending our position. However, we expect increased audit activity in Mexico and anticipate the tax authorities will issue additional assessments and continue to pursue legal actions for all audit claims. We believe additional audit claims in the range of $9 to $10 million attributable to other business tax returns may be assessed against us. We have contested, or intend to contest, the audit findings, including through litigation if necessary, and we do not believe that there is greater than 50 percent likelihood that additional taxes will be incurred. Accordingly, no accrual has been made for such amounts.

We maintain certain insurance coverage against specified marine perils, including liability for physical damage to our drilling rigs, and loss of hire on certain of our rigs. The damage caused in 2005 and 2008 by Hurricanes Katrina, Rita and Ike negatively impacted the energy insurance market, resulting in more restrictive and expensive coverage for U.S. named windstorm perils. Accordingly, effective March 2009, we elected to self-insure this exposure to our units in the U.S. portion of the Gulf of Mexico. Our rigs located in the Mexican portion of the Gulf of Mexico remain covered by commercial insurance for windstorm damage. In addition, we maintain physical damage deductibles of $25 million per occurrence for rigs located in the U.S., Mexico, Brazil, Southeast Asia, the North Sea, New Zealand and Australia and $15 million per occurrence for rigs operating in West Africa, the Middle East, India, and the Mediterranean Sea. The loss of hire coverage applies only to our rigs operating under contract with a dayrate equal to or greater than $200,000 a day and is subject to a 45-day waiting period for each unit and each occurrence.

Although we maintain insurance in the geographic areas in which we operate, pollution, reservoir damage and environmental risks generally are not fully insurable. Our insurance policies and contractual rights to indemnity may not adequately cover our losses or may have exclusions of coverage for some losses. We do not have insurance coverage or rights to indemnity for all risks, including loss of hire insurance on most of the rigs in our fleet. Uninsured exposures may include expatriate activities prohibited by U.S. laws and regulations, radiation hazards, certain loss or damage to property on board our rigs and losses relating to shore-based terrorist acts or strikes. If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it could materially adversely affect our financial position, results of operations or cash flows. Additionally, there can be no assurance that those parties with contractual obligations to indemnify us will necessarily be financially able to indemnify us against all these risks.

In October 2011, we were assessed a fine by the Brazilian government in the amount of R$238,000 (approximately $135,000) in connection with the inadvertent discharge of approximately 200 barrels of drilling fluid from one of our vessels offshore Brazil in November 2010. We plan on appealing this judgment to the full extent permissible by law.

We carry protection and indemnity insurance covering marine third party liability exposures, which also includes coverage for employer’s liability resulting from personal injury to our offshore drilling crews. Our protection and indemnity policy currently has a standard deductible of $10 million per occurrence, with maximum liability coverage of $750 million.

In connection with our capital expenditure program, we had outstanding commitments, including shipyard and purchase commitments of approximately $3.4 billion at September 30, 2011.

We have entered into agreements with certain of our executive officers, as well as certain other employees. These agreements become effective upon a change of control of Noble-Swiss (within the meaning set forth in the agreements) or a termination of employment in connection with or in anticipation of a change of control, and remain effective for three years thereafter. These agreements provide for compensation and certain other benefits under such circumstances.

Internal Investigation

In 2007, we began, and voluntarily contacted the SEC and the U.S. Department of Justice (“DOJ”) to advise them of an internal investigation of the legality under the United States Foreign Corrupt Practices Act (“FCPA”) and local laws of certain reimbursement payments made by our Nigerian affiliate to our customs agents in Nigeria. In 2010, we finalized settlements of this matter with each of the SEC and the DOJ. Pursuant to these settlements, we agreed to pay fines and penalties to the DOJ and the SEC and to certain undertakings, including refraining from violating the FCPA and other anti-corruption laws, self-reporting any violations of the FCPA or such laws to the DOJ and reporting to the DOJ on an annual basis our progress on anti-corruption compliance matters. Our ability to comply with the terms of the settlements is dependent on the success of our ongoing compliance program, including our ability to continue to manage our agents and supervise, train and retain competent employees, and the efforts of our employees to comply with applicable law and our code of business conduct and ethics.

Any similar investigations or charges and any additional sanctions we may incur as a result of any such investigation could damage our reputation and result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, results of operations or financial condition. Further, resolving any such investigation could be expensive and consume significant time and attention of our senior management.

As of September 30, 2011, all of our rigs operating in Nigeria were operating under temporary import permits. To date, we have been successful in obtaining new, or extending existing, temporary import permits. However, there can be no assurance that we will be able to obtain new permits or further extensions of permits necessary to continue the operation of our rigs in Nigeria. If we cannot obtain a new permit or an extension necessary to continue operations of any rig, we may need to cease operations under the drilling contract for such rig and relocate such rig from Nigerian waters. We cannot predict what impact these events may have on any such contract or our business in Nigeria, and we could face additional fines and sanctions in Nigeria. Furthermore, we cannot predict what changes, if any, relating to temporary import permit policies and procedures may be established or implemented in Nigeria in the future, or how any such changes may impact our business there.

Note 14 — Segment and Related Information

We report our contract drilling operations as a single reportable segment: Contract Drilling Services. The consolidation of our contract drilling operations into one reportable segment is attributable to how we manage our business, and the fact that all of our drilling fleet is dependent upon the worldwide oil and gas industry. The mobile offshore drilling units comprising our offshore rig fleet operate in a single, global market for contract drilling services and are often redeployed globally in response to changing demands of our customers, which consist largely of major non-U.S. and government owned/controlled oil and gas companies throughout the world. Our Contract Drilling Services segment currently conducts contract drilling operations principally in the Middle East, India, the U.S. Gulf of Mexico, Mexico, the Mediterranean, the North Sea, Brazil, West Africa and the Asian Pacific.

We evaluate the performance of our operating segment primarily based on operating revenues and net income. Summarized financial information of our reportable segments for the three and nine months ended September 30, 2011 and 2010 is shown in the following table. The “Other” column includes results of labor contract drilling services in Canada and Alaska, as well as corporate related items.

Note 15 — Accounting Pronouncements

In October 2009, the FASB issued guidance that impacts the recognition of revenue in multiple-deliverable arrangements. The guidance establishes a selling-price hierarchy for determining the selling price of a deliverable. The goal of this guidance is to clarify disclosures related to multiple-deliverable arrangements and to align the accounting with the underlying economics of the multiple-deliverable transaction. This guidance is effective for fiscal years beginning on or after June 15, 2010. The adoption of this guidance did not have a material impact on our financial condition, results of operations, cash flows or financial disclosures.

In January 2010, the FASB issued guidance relating to the disclosure of the fair value of assets. This guidance calls for additional information to be given regarding the transfer of items in and out of respective categories. In addition, it requires additional disclosures regarding the purchase, sales, issuances, and settlements of assets that are classified as level three within the FASB fair value hierarchy. This guidance is generally effective for annual and interim periods ending after December 15, 2009. However, the disclosures about purchases, sales, issuances and settlements in the roll-forward activity in Level 3 fair value measurements were deferred until fiscal years beginning after December 15, 2010. The adoption of this guidance did not have a material impact on our financial condition, results of operations, cash flows or financial disclosures.

In December 2010, the FASB issued guidance that requires a public entity to disclose pro forma information for business combinations that occurred in the current reporting period. The disclosures include pro forma revenue and earnings of the combined entity for the current reporting period as though the acquisition date for all business combinations that occurred during the year had been as of the beginning of the annual reporting period. If comparative financial statements are presented, the pro forma revenue and earnings of the combined entity for the comparable prior reporting period should be reported as though the acquisition date for all business combinations that occurred during the current year had been as of the beginning of the comparable prior annual reporting period. The guidance is effective for annual reporting periods beginning on or after December 15, 2010. The adoption of this guidance did not have a material impact on our financial condition, results of operations, cash flows or financial disclosures.

In May 2011, the FASB issued guidance that modified the wording used to describe many of the requirements in accounting literature for measuring fair value and for disclosing information about fair value measurements. The goal of the amendment is to create consistency between the United States and international accounting standards. The guidance is effective for annual and interim reporting periods beginning on or after December 15, 2011. While we are still evaluating this guidance, the adoption of this guidance should not have a material impact on our financial condition, results of operations, cash flows or financial disclosures.

In June 2011, the FASB issued guidance that allows an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendment no longer allows an entity to show changes to other comprehensive income solely through the statement of equity. For publicly traded entities, the guidance is effective for annual and interim reporting periods beginning on or after December 15, 2011. While we are still evaluating this guidance, the adoption of this guidance will not have a material impact on our financial condition, results of operations, cash flows or financial disclosures.

The indenture governing the Senior Notes due 2013 provides that each guarantee may be released in connection with certain events, including upon a merger, consolidation or transfer of all of the assets of Noble Cayman or the guarantor with or to another person in compliance with the indenture (provided the acquiror assumes the guarantee), upon a liquidation of the guarantor in compliance with the indenture (provided any acquiror assumes the guarantee), or upon the guarantor’s ceasing to be a wholly-owned subsidiary of Noble-Cayman.

Noble-Cayman is a full and unconditional guarantor of NHIL’s 7.375% Senior Notes due 2014, which had an outstanding principal balance of $250 million at September 30, 2011.

Noble-Cayman is a full and unconditional guarantor of NHIL’s 3.45% Senior Notes due 2015, 4.90% Senior Notes due 2020 and 6.20% Senior Notes due 2040. The aggregate principal balance of these three tranches of senior notes at September 30, 2011 was $1.25 billion.

Noble-Cayman is a full and unconditional guarantor of NHIL’s 3.05% Senior Notes due 2016, 4.625% Senior Notes due 2021 and 6.05% Senior Notes due 2041. The aggregate principal balance of these three tranches of senior notes at September 30, 2011 was $1.1 billion.

We cannot control such risk factors and other uncertainties, and in many cases, we cannot predict the risks and uncertainties that could cause our actual results to differ materially from those indicated by the forward-looking statements. You should consider these risks and uncertainties when you are evaluating us.

Executive Overview

Noble is a leading offshore drilling contractor for the oil and gas industry. At September 30, 2011, our fleet consisted of 79 mobile offshore drilling units located worldwide as follows: 14 semisubmersibles, 14 drillships, 49 jackups and two submersibles. Additionally, we have one floating production storage and offloading unit (“FPSO”). At September 30, 2011, we had 13 units under construction.

Outlook

During the third quarter of 2011, we began to see some stability in the offshore drilling market after a period of volatility, which occurred following the Deepwater Horizon incident and the U.S. governmental response to the incident. In the U.S. Gulf of Mexico, the granting of permits and publication of new safety rules has led to more stable activity levels within the industry itself, especially as it relates to the deepwater markets. This resumption of activity has led to greater investment within the Gulf of Mexico and is contributing to an improvement in dayrates for deepwater and ultra-deepwater rigs worldwide. While there are still risks, including potential third party environmental lawsuits targeting the permitting process, possible new drilling regulations, a failure of the Bureau of Ocean Energy Management Regulation and Enforcement (“BOEMRE”) to issue permits in a timely manner and the adoption by individual operators of new drilling or equipment standards exceeding those required by regulatory bodies. We believe those risks may be reduced as long as rigs continue to work without incident in the Gulf of Mexico.

The offshore drilling market displayed notable indications of improvement in the third quarter even though there continues to be uncertainty regarding the sustainability of the global economic recovery, which is proceeding unevenly in different geographic regions. In addition to the political instability in certain oil producing nations in the Middle East and North Africa, there is also uncertainty regarding recovery in the credit markets, particularly in Europe and North America. During the first nine months of 2011, oil prices fluctuated as a result of supply side concerns in response to political unrest in the Middle East and North Africa. Natural gas prices in the United States fluctuated during the first nine months of the year, but ended the period in-line with year-end 2010 pricing. We believe there continue to be competing factors which could impact the volatility in the offshore drilling market and the prices of oil and gas commodities for the foreseeable future.

Even with the instability in the global economy noted above, we have seen an increase in demand for offshore drilling services in the first nine months of 2011. While the risk of negative developments in the U.S. Gulf of Mexico could continue to have an impact on the deepwater market segment in the short-term, we believe that the long-term outlook continues to strengthen. Market dayrates for new ultra-deepwater units remain generally above $450,000, which is significantly lower than the peak rates achieved in 2007-2008, but higher than rates seen in 2010. Short-term fixtures for very high specification units have exceeded $500,000, and we believe this is an indication of where the market could be going should there continue to be a strong demand for ultra-deepwater drilling units. Although demand in the jackup segment decreased slightly during 2010, utilization rates for units stabilized in the first nine months of 2011, especially for those units equipped with standard drilling features. We continue to see differentiation in the jackup market segment with newer units having utilization rates exceeding those units that entered service before 2000. Likewise, there has been a bifurcation of dayrates between older and newer units in the jackup market with newer units earning a premium as customers display a preference for technologically advanced and efficient drilling alternatives.

Demand for our drilling services generally depends on a variety of economic and political factors, including worldwide demand for oil and gas, the ability of the Organization of Petroleum Exporting Countries (“OPEC”) to set and maintain production levels and pricing, the level of production of non-OPEC countries and the policies of various governments addressing access to their oil and gas reserves. Our results of operations depend on offshore drilling activity worldwide. Historically, oil and gas prices and market expectations of potential changes in these prices have significantly affected that level of activity. Generally, higher oil and natural gas prices or our customers’ expectations of higher prices result in greater demand for our services. Demand for our services is also a function of the worldwide supply of mobile offshore drilling units. Industry analysts widely acknowledge that a significant expansion of industry supply of both jackups and ultra-deepwater units has commenced, the majority of which currently have no contract. The introduction of additional non-contracted rigs into the marketplace could have an adverse effect on demand for our services or the dayrates we are able to achieve.

In addition, as a result of exploration discoveries offshore Brazil, Petroleo Brasileiro S.A. (“Petrobras”), the Brazilian national oil company, announced a plan to construct up to 28 deepwater rigs in Brazil and accepted bids in 2010 to construct these units from a number of shipyards and drilling contractors. A deepwater drilling rig construction industry possessing the scope and experience to efficiently address this volume of work does not currently exist in Brazil and Noble did not participate in these bids primarily because we viewed the capital risk associated with constructing a unit in Brazil as inappropriate. Petrobras awarded the first tranche of seven drillships to a Brazilian shipyard for delivery beginning in 2015. In March 2011, Petrobras cancelled the bids for the remaining 21 newbuild units. In June 2011, Petrobras issued a new tender to build 21 ultra deepwater rigs in Brazil to operate with Petrobras under 10 to 15 year contracts with drilling operations commencing within 48 months after the contract is awarded. Petrobras opened the tenders late October 2011, receiving offers for the 21 rigs from local Brazilian and Norwegian based drillers, which Petrobras is currently reviewing. Petrobras is also reviewing offers received for existing deepwater drilling units. The potential increase in supply from the Petrobras newbuilds could also adversely impact overall industry dayrates and economics.

As of September 30, 2011, we have 12 rigs, including the deepwater semisubmersible rig Noble Max Smith under contract in Mexico with Pemex Exploracion y Produccion (“Pemex”), and seven of these rigs have contracts scheduled to expire in 2011. Pemex continues to tender for additional jackup rigs as they attempt to increase the number of working rigs. Some previous tenders published by Pemex contained a requirement that certain units must have entered service since the year 2000. While Pemex did not succeed in securing a significant number of newer rigs from those published tenders, we cannot predict whether this age requirement will be present in future Pemex tenders. If this requirement is present in future tenders, it could require us to seek work for our rigs in other locations, as the ages of our rigs currently operating in Mexico do not meet this requirement. If such work is not available, it could lead to additional idle time on some of our rigs. We cannot predict how many rigs might be affected or how long they could remain idle. We remain optimistic that many, if not all, of our rigs currently operating in Mexico will be able to continue to secure long-term work with Pemex.

In January 2011, we announced the signing of a Memorandum of Understanding (“MOU”) with Petrobras regarding operations in Brazil. Under the terms of the MOU, we would substitute the drillship Noble Phoenix, then under contract with Royal Dutch Shell (“Shell”) in Southeast Asia, for the drillship Noble Muravlenko. In January 2011, Shell agreed to release the Noble Phoenix from its contract, which was effective in March 2011. During the second quarter of 2011, Petrobras formally approved the rig substitution. We expect that acceptance of the Noble Phoenix will take place in the first quarter of 2012. In connection with the cancelation of the contract on the Noble Phoenix, we recognized a non-cash gain of approximately $52.5 million during the first quarter of 2011, which represents the unamortized fair value of the in-place contract assumed in connection with the Frontier acquisition.

In connection with our existing drilling contracts with Petrobras for two of our drillships operating in Brazil, we approved certain shipyard reliability upgrade projects for these drillships, the Noble Leo Segerius and the Noble Roger Eason. These upgrade projects, planned through 2012, are designed to enhance the reliability and operational performance of these drillships. During the first quarter, the Noble Leo Segerius entered a shipyard in Brazil for its reliability upgrade. There are a number of risks associated with shipyard projects of this nature, particularly in Brazil, including potential project delays and cost overruns because of labor, customs, local shipyard, local content and other issues. In addition, the drilling contracts for these vessels provide Petrobras with certain rights of termination in the event of excessive downtime, and it is possible that Petrobras could exercise this right in the future with respect to one or both of these drillships. We intend to continue to closely monitor and discuss with Petrobras the status of these projects and plan to take appropriate steps to mitigate identified risks, which depending upon the circumstances, could involve a variety of options.

While we cannot predict the future level of demand or dayrates for our drilling services or future conditions in the offshore contract drilling industry, we continue to believe we are well positioned within the industry and believe our acquisition of Frontier and recent newbuild announcements further strengthen our position, especially in deepwater drilling.

Results and Strategy

In the third quarter of 2011, we recognized net income attributable to Noble-Swiss of $135 million, or $0.53 per diluted share, on total revenues of $738 million. Sequential results of key metrics are as follows:


	Three Months Ended
	September 30,			June 30,
	2011			2011
Average dayrate	$	151,782		$	140,296
Average utilization		76	%		70	%
Daily contract drilling services costs	$	77,205		$	80,985
Contract drilling services margin		49	%		43	%

We have actively expanded our offshore drilling and deepwater capabilities in recent years through the construction of new rigs, and as part of this technical and operational expansion we plan to continue pursuing opportunities to upgrade our fleet to achieve greater technological capability, which would lead to increased drilling efficiencies. Our business strategy also focuses on the active expansion of our worldwide offshore drilling and deepwater capabilities through upgrades and modifications, acquisitions, divestitures of lower specification units and the deployment of our drilling assets in important oil and gas producing areas. At September 30, 2011, we continued our newbuild strategy with the following 13 projects:

•

two dynamically positioned, ultra-deepwater, harsh environment Globetrotter-class drillships, which are scheduled to be delivered in the fourth quarter of 2011 and the second quarter of 2013, respectively and complete acceptance testing in the first quarter of 2012 and the fourth quarter of 2013, respectively;

•

one dynamically positioned, ultra-deepwater, harsh environment Bully-class drillship owned through a joint venture with Shell which is scheduled to be delivered in the fourth quarter of 2011 and complete acceptance testing in the first quarter of 2012;

•

four dynamically positioned, ultra-deepwater, harsh environment drillships under construction at Hyundai Heavy Industries Co. Ltd. which are estimated to be delivered from the shipyard to begin acceptance testing as follows: the second quarter of 2013, the fourth quarter of 2013, the second quarter of 2014, and the second half of 2014, respectively; and

•

six high-specification heavy duty, harsh environment jackup rigs which are estimated to be delivered from the shipyard to begin acceptance testing as follows: first quarter of 2013, third quarter of 2013, fourth quarter of 2013, first quarter of 2014, fourth quarter of 2014 and first quarter of 2015, respectively.

Of our 13 rigs under construction as of September 30, 2011, four drillships and all six jackups are being constructed at a shipyard with a strong history of successful execution. Also, four of the drillships are contracted for five years or more, while the remaining nine rigs are being constructed without contracts.

As part of our business strategy, we continue to review our fleet and the strategic benefit of our lower specification units. As part of this process, we may dispose of some of our lower specification units, and we are considering potential options.

(1)		Represents a three-month period beginning October 1, 2011.

(2)		Our drilling contracts with Petrobras provide an opportunity for us to earn performance bonuses based on downtime experienced for our rigs operating offshore Brazil. With respect to our semisubmersibles operating offshore Brazil for Petrobras, we have included in our backlog an amount equal to 75 percent of potential performance bonuses for such semisubmersibles, which amount is based on and generally consistent with our historical earnings of performance bonuses for these rigs. With respect to our drillships presently operating offshore Brazil for Petrobras, we (a) have not included in our backlog any performance bonuses for periods prior to the commencement of certain upgrade projects planned for 2011 through 2012, which projects are designed to enhance the reliability and operational performance of these drillships, and (b) have included in our backlog an amount equal to 75 percent of potential performance bonuses for periods after the estimated completion of such upgrade projects. Our backlog for semisubmersibles/drillships includes approximately $266 million attributable to these performance bonuses.

		The drilling contracts with Shell for the Noble Globetrotter I, Noble Globetrotter II, Noble Jim Thompson, Noble Jim Day and Noble Clyde Boudreaux, as well as the letter of intent for the unnamed HHI Drillship I, provide opportunities for us to earn performance bonuses based on key performance indicators as defined by Shell. With respect to these contracts, we have included in our backlog an amount equal to 75 percent of the potential performance bonuses for these rigs, except for the Noble Clyde Boudreaux where limited bonus is expected. Our backlog for these rigs includes approximately $480 million attributable to these performance bonuses.

(3)		Our drilling contracts with Pemex for certain jackups operating offshore in Mexico are subject to price review and adjustment of the rig dayrate. Presently, the contract for one jackup has a dayrate indexed to the world average of the highest dayrates published by ODS-Petrodata. After an initial firm dayrate period, the dayrate is generally adjusted quarterly based on formulas calculated from the index. Our contract drilling services backlog has been calculated using the September 30, 2011 index-based dayrate for periods subsequent to the firm dayrate period.


(4)		a) Pemex has the ability to cancel its drilling contracts on 30 days or less notice without Pemex’s making an early termination payment. As of September 30, 2011, we had twelve rigs contracted to Pemex in Mexico, plus one additional rig scheduled to go to work for Pemex in late December 2011, and our backlog includes approximately $387 million related to such contracts at September 30, 2011.


b)		Our drilling contracts generally provide the customer an early termination right in the event we fail to meet certain performance standards, including downtime thresholds. For example, Petrobras has the right to terminate its contracts in the event of excessive downtime. While we do not currently anticipate any cancellations as a result of events that have occurred to date, clients may from time to time have the contractual right to do so, which is the case with the drilling contracts for the Noble Dave Beard and the Noble Paul Wolff. However, we have not received any notification concerning contract cancellations to date.


(5)		Percentages take into account additional capacity from the estimated dates of deployment of our newbuild rigs that are scheduled to commence operations during 2011 through 2015.

(6)		It is not possible to accurately determine the impact to our revenues or backlog resulting from efforts by operators to cancel or modify drilling contracts due to U.S. government imposed restrictions and the rigorous scrutiny for issuance of new drilling permits, and other consequences of actions by the U.S. government. At September 30, 2011, backlog related to our U.S. Gulf of Mexico deepwater rigs totaled $5.5 billion, $206 million of which represents backlog for the three-month period ending December 31, 2011.

		We entered into an agreement with Shell, effective June 27, 2010, which provides that Shell may suspend the contracts on three of our units operating in the U.S. Gulf of Mexico during any period of regulatory restriction by paying reduced suspension dayrates in lieu of the normal operating dayrates. The term of the initial contract is also extended by the suspension period. The impact of this agreement is to shift backlog among periods with an immaterial increase to total backlog because of the reduced suspension rates.

(7)		Noble and a subsidiary of Shell are involved in joint venture agreements to build, operate, and own both the Noble Bully I and the Noble Bully II. Pursuant to these agreements, each party has an equal 50 percent share in both vessels. As of September 30, 2011, the combined amount of backlog for these rigs totaled $2.4 billion, all of which is included in our backlog. Noble’s net interest in the backlog for these rigs was $1.2 billion.

Our contract drilling services backlog reported above reflects estimated future revenues attributable to both signed drilling contracts and letters of intent that we expect will become binding contracts. A letter of intent is generally subject to customary conditions, including the execution of a definitive drilling contract. For a number of reasons, it is possible that some customers that have entered into letters of intent will not enter into signed drilling contracts. We calculate backlog for any given unit and period by multiplying the full contractual operating dayrate for such unit by the number of days remaining in the period. The reported contract drilling services backlog does not include amounts representing revenues for mobilization, demobilization and contract preparation, which are not expected to be significant to our contract drilling services revenues, amounts constituting reimbursables from customers or amounts attributable to uncommitted option periods under drilling contracts or letters of intent.

The amount of actual revenues earned and the actual periods during which revenues are earned may be different than the backlog amounts and backlog periods set forth in the table above for various factors, including, but not limited to, shipyard and maintenance projects, operational downtime, weather conditions, bonuses and other factors that result in applicable dayrates lower than the full contractual operating dayrate. In addition, amounts included in the backlog may change because drilling contracts may be varied or modified by mutual consent or customers may exercise early termination rights contained in some of our drilling contracts or decline to enter into a drilling contract after executing a letter of intent. As a result, our backlog as of any particular date may not be indicative of our actual operating results for the subsequent periods for which the backlog is calculated.

As of September 30, 2011, we estimate Shell and Petrobras represented approximately 63% and 22%, respectively, of our backlog.

Internal Investigation

In 2007, we began, and voluntarily contacted the SEC and the U.S. Department of Justice (“DOJ”) to advise them of, an internal investigation of the legality under the United States Foreign Corrupt Practices Act (“FCPA”) and local laws of certain reimbursement payments made by our Nigerian affiliate to our customs agents in Nigeria. In 2010, we finalized settlements of this matter with each of the SEC and the DOJ. Pursuant to these settlements, we agreed to pay fines and penalties to the DOJ and the SEC and to certain undertakings, including refraining from violating the FCPA and other anti-corruption laws, self-reporting any violations of the FCPA or such laws to the DOJ and reporting to the DOJ on an annual basis our progress on anti-corruption compliance matters. Our ability to comply with the terms of the settlements is dependent on the success of our ongoing compliance program, including our ability to continue to manage our agents and supervise, train and retain competent employees, and the efforts of our employees to comply with applicable law and our code of business conduct and ethics.

In January 2011, the Nigerian Economic and Financial Crimes Commission and the Nigerian Attorney General Office initiated an investigation into these same activities. A subsidiary of Noble-Swiss resolved this matter through the execution of a non-prosecution agreement dated January 28, 2011. Pursuant to this agreement, the subsidiary paid $2.5 million to resolve all charges and claims of the Nigerian Government. Any similar investigations or charges and any additional sanctions we may incur could damage our reputation and result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, results of operations or financial condition. Further, resolving any such investigation could be expensive and consume significant time and attention of our senior management.

In 2010, the Nigerian Oil and Gas Industry Content Development Bill was signed into law. The law is designed to create Nigerian content in operations and transactions within the Nigerian oil and gas industry. The law sets forth certain requirements for the utilization of Nigerian human resources and goods and services in oil and gas projects and creates a Nigerian Content Development and Monitoring Board (“NCD Board”) to implement and monitor the law and develop regulations pursuant to the law. The law also establishes a Nigerian Content Development Fund to fund the implementation of the law. The implementation of the law is ongoing and both the manner and timing of final implementation is uncertain. We have participated in a number of meetings with the NCD Board and are analyzing how we might reorganize our operations in Nigeria to meet these requirements, including creating third party noncontrolling interests in our operating assets. We cannot predict the impact the new law may have on our existing or future operations in Nigeria, but our operations there could be significantly and adversely affected.

Results of Operations

For the Three Months Ended September 30, 2011 and 2010

General

Net income attributable to Noble Corporation (Noble-Swiss) for the three months ended September 30, 2011 (the “Current Quarter”) was $135 million, or $0.53 per diluted share, on operating revenues of $738 million, compared to net income for the three months ended September 30, 2010 (the “Comparable Quarter”) of $86 million, or $0.34 per diluted share, on operating revenues of $613 million.

The consolidated financial statements of Noble-Swiss include the accounts of Noble-Cayman, and Noble-Swiss conducts substantially all of its business through Noble-Cayman and its subsidiaries. As a result, the financial position and results of operations for Noble-Cayman, and the reasons for material changes in the amount of revenue and expense items between 2011 and 2010, would be the same as the information presented below regarding Noble-Swiss in all material respects, except operating income for Noble-Cayman for the three months ended September 30, 2011 was $19 million higher than operating income for Noble-Swiss for the same period, primarily as a result of depreciation related to Swiss-owned assets and operating costs directly attributable to Noble-Swiss for stewardship related services.

Rig Utilization, Operating Days and Average Dayrates

Operating revenues and operating costs and expenses for our contract drilling services segment are dependent on three primary metrics — rig utilization, operating days and dayrates. The following table sets forth the average rig utilization, operating days and average dayrates for our rig fleet for the three months ended September 30, 2011 and 2010:

(1)		We record reimbursements from customers for out-of-pocket expenses as operating revenues and the related direct costs as operating expenses. Changes in the amount of these reimbursables generally do not have a material effect on our financial position, results of operations or cash flows.

Operating Revenues. Increases in contract drilling services revenues for the Current Quarter as compared to the Comparable Quarter were driven by increases in both average dayrates and operating days. The 20 percent increase in average dayrates increased revenues by approximately $117 million, and the slight increase in operating days increased revenues by an additional $3 million.

The increase in contract drilling services revenues primarily relates to our semisubmersibles and jackups, which generated approximately $160 million and $13 million more revenue, respectively, in the Current Quarter.

The increase in semisubmersible average dayrates resulted in a $155 million increase in revenues from the Comparable Quarter while the increase in operating days of three percent resulted in an additional $5 million increase in revenues. The increase in semisubmersibles revenue is a result of drilling restrictions in the U.S. Gulf of Mexico in the Comparable Quarter, where lower standby rates replaced the standard operating dayrates for a majority of our contracts. The increase in operating days is primarily from the Noble Jim Day and the Noble Homer Ferrington, which were added to the fleet subsequent to September 30, 2010.

The six percent increase in jackup operating days resulted in an $18 million increase in revenues, which was partially offset by a decrease in jackup average dayrates of two percent which resulted in a $5 million decrease in revenues from the Comparable Quarter. The increase in utilization primarily related to rigs in Mexico that commenced contracts in the second quarter of 2011 and operated for the entire Current Quarter. The reduction in average dayrates resulted primarily from the contractual re-pricing of rigs in the Middle East, the North Sea, and Mexico for changes in market conditions in the global shallow water market.

The increases in revenue for the above rig classes were partially offset by lower revenues from our drillships and FPSO/submersibles. Revenue from our drillships decreased $33 million in the Current Quarter as compared to the Comparable Quarter. The decrease was primarily attributable to a number of rigs being in the shipyard or stacked during the Current Quarter. Revenue from our FPSO, the Noble Seillean, decreased $20 million as it did not operate in the Current Quarter.

Operating Costs and Expenses. Contract drilling services operating costs and expenses increased $43 million for the Current Quarter as compared to the Comparable Quarter. In addition to the rigs added to the fleet as part of the Frontier acquisition, the Noble Jim Day was placed into service in January 2011. These additional units added approximately $15 million of operating costs in the Current Quarter. Excluding the additional expenses related to these rigs, our contract drilling costs increased $28 million in the Current Quarter from the Comparable Quarter. This change was primarily driven by an $11 million increase in labor and a $10 million increase in mobilization, transportation and fuel costs related to rigs returning, or preparing to return, to work in the Current Quarter, a $4 million increase in safety and training costs and a $3 million increase in rotation costs.

The increase in depreciation and amortization in the Current Quarter from the Comparable Quarter was primarily attributable to depreciation on the Noble Jim Day, rigs added to the fleet as part of the Frontier acquisition and additional depreciation related to other capital expenditures on our fleet since the Comparable Quarter.

**		Not a meaningful percentage

Operating Revenues and Costs and Expenses. The increase in both revenue and expense primarily relates to the commencement of a refurbishment project with our customer, Shell, for one of its rigs to be operated under a labor contract in Alaska, combined with operational increases and foreign currency fluctuations in our Canadian operations.

The increase in depreciation is for additional corporate-related assets placed in service since the Comparable Quarter.

Other Income and Expenses

Selling, General and Administrative Expenses. Consolidated selling, general and administrative expenses increased $2 million in the Current Quarter as compared to the Comparable Quarter. The increase relates to a $3 million increase in ongoing legal and tax expenses and a $2 million increase in employee-related and miscellaneous costs in the Current Quarter, partially offset by a $3 million decrease related to our FCPA investigation in the Comparable Quarter.

Interest Expense, net of amount capitalized. Interest expense, net of amount capitalized, increased $7 million in the Current Quarter as compared to the Comparable Quarter. The increase is a result of $1.25 billion of debt issued in July 2010, which was used to partially fund the Frontier acquisition, $1.1 billion of debt issued in February 2011, which was primarily used to repay the outstanding balance on our revolving credit facility and to repay our portion of outstanding debt under the joint venture credit facilities, and the $715 million currently drawn on our credit facilities.

Income Tax Provision. Our income tax provision decreased $3 million in the Current Quarter primarily as a result of a lower effective tax rate of 12 percent in the Current Quarter as compared to 19 percent in the Comparable Quarter, which decreased income tax expense by approximately $12 million. The decrease in the effective tax rate was a result of certain discrete tax items totaling approximately $11 million. Partially offsetting the decrease is an increase in pre-tax earnings of approximately 43 percent, which increased income tax expense by approximately $9 million in the Current Quarter.

For the Nine Months Ended September 30, 2011 and 2010

General

Net income attributable to Noble Corporation (Noble-Swiss) for the nine months ended September 30, 2011 (the “Current Period”) was $244 million, or $0.96 per diluted share, on operating revenues of $1.9 billion, compared to net income for the nine months ended September 30, 2010 (the “Comparable Period”) of $675 million, or $2.62 per diluted share, on operating revenues of $2.2 billion.

The consolidated financial statements of Noble-Swiss include the accounts of Noble-Cayman, and Noble-Swiss conducts substantially all of its business through Noble-Cayman and its subsidiaries. As a result, the financial position and results of operations for Noble-Cayman, and the reasons for material changes in the amount of revenue and expense items between 2011 and 2010, would be the same as the information presented below regarding Noble-Swiss in all material respects, except operating income for Noble-Cayman for the nine months ended September 30, 2011 was $46 million higher than operating income for Noble-Swiss for the same period, primarily as a result of depreciation related to Swiss owned assets and operating costs directly attributable to Noble-Swiss for stewardship related services.

Operating Revenues. Decreases in contract drilling services revenues for the Current Period as compared to the Comparable Period were driven by reductions in both average dayrates and operating days. The six percent decrease in average dayrates reduced revenues by approximately $108 million, and the seven percent decrease in operating days decreased revenues by an additional $136 million.

The decrease in contract drilling services revenues primarily relates to our jackups, semisubmersibles and FPSO/submersibles, which generated approximately $242 million, $29 million and $19 million less revenue, respectively, in the Current Period.

The decrease in jackup average dayrates of 17 percent resulted in a $146 million decrease in revenues from the Comparable Period. The reduction in average dayrates was primarily from the contractual re-pricing of rigs in the Middle East, the North Sea, and Mexico for changes in market conditions in the global shallow water market. The 10 percent decline in jackup operating days resulted in a $96 million decline in revenues. The decrease in utilization primarily related to rigs coming off of contract in Mexico during the first quarter of 2011, the majority of which did not return to work until the second quarter.

The decrease in semisubmersible dayrates of four percent resulted in the $38 million decrease in revenues from the Comparable Period. The decrease in semisubmersibles revenue is a result of drilling restrictions in the U.S. Gulf of Mexico where lower standby rates replaced the standard operating dayrates for a majority of our contracts during the first half of the year. These decreases were partially offset by a $9 million increase in revenues during the Current Period driven by 32 additional operating days.

Revenue from our FPSO, the Noble Seillean, decreased $19 million as it did not operate in the Current Period.

The decreases in revenue for the above rig classes were partially offset by an increase in revenue of $47 million from our drillships. The increase was primarily attributable to a nine percent increase in average dayrates and 12 percent increase in operating days, which contributed additional revenue in the Current Period of $21 million and $25 million, respectively. The increase is primarily attributable to operations from the drillships added to the fleet as part of the Frontier acquisition.

Operating Costs and Expenses. Contract drilling services operating costs and expenses increased $156 million for the Current Period as compared to the Comparable Period. In addition to the rigs added to the fleet as part of the Frontier acquisition, the Noble Dave Beard and the Noble Jim Day were placed into service in March 2010 and January 2011, respectively. These additions added approximately $108 million of operating costs in the Current Period. Excluding the additional expenses related to these rigs, our contract drilling costs increased $48 million in the Current Period from the Comparable Period. This change was primarily driven by a $13 million increase in maintenance and rig-related expense, $12 million increase in mobilization costs, $8 million increase in fuel and transportation costs and $3 million increase in labor costs related to our rigs returning, or preparing to return, to work in Brazil and Mexico, $6 million increase in rotation costs and $6 million increase in safety and training costs.

The increase in depreciation and amortization in the Current Period from the Comparable Period was primarily attributable to depreciation on newbuilds added to the fleet, the addition of the Frontier rigs and additional depreciation related to other capital expenditures on our fleet since the Comparable Period.

Operating Revenues and Costs and Expenses. The increase in both revenue and expense primarily relates to the initial start-up costs and commencement of a refurbishment project with our customer, Shell, for one of its rigs to be operated under a labor contract in Alaska, combined with operational increases and foreign currency fluctuations in our existing Canadian operations.

The increase in depreciation is for additional corporate-related assets placed in service since the Comparable Period.

Other Income and Expenses

Selling, General and Administrative Expenses. Consolidated selling, general and administrative expenses increased $2 million in the Current Period as compared to the Comparable Period. The increase relates to a $5 million increase in ongoing legal and tax expenses and a $3 million increase in employee-related and miscellaneous costs in the Current Period, partially offset by a $6 million decrease related to our FCPA investigation in the Comparable Period.

Interest Expense, net of amount capitalized. Interest expense, net of amount capitalized, increased $40 million in the Current Period as compared to the Comparable Period. The increase is a result of $1.25 billion of debt issued in July 2010, which was used to partially fund the Frontier acquisition, $1.1 billion of debt issued in February 2011, which was primarily used to repay the outstanding balance on our revolving credit facility and to repay our portion of outstanding debt under the joint venture credit facilities, and Current Period drawdowns on the credit facilities.

Income Tax Provision. Our income tax provision decreased $84 million in the Current Period primarily from a decline in pre-tax earnings of approximately 64 percent, which reduced income tax expense by approximately $81 million in the Current Period. The remaining $3 million decrease is a result of a lower effective tax rate of 15 percent in the Current Period as compared to 16 percent in the Comparable Period. The decrease in the effective tax rate was a result of certain discrete tax items totaling approximately $17 million, partially offset by a change in our geographic revenue mix primarily resulting from drilling restrictions in the U.S. Gulf of Mexico.

Liquidity and Capital Resources

Overview

Net cash from operating activities for the Current Period was $474 million, which compared to $1.3 billion in the Comparable Period. The decrease in net cash from operating activities in the Current Period was primarily attributable to a significant decline in net income coupled with an increase in accounts receivable. The increase in accounts receivable is primarily related to the increased fleet activity in 2011 and certain disputed amounts, which we believe will ultimately be collected. During the Current Period, we entered into an additional $600 million revolving credit facility, and at September 30, 2011 we had $485 million available under our credit facilities. We had working capital of $352 million and $110 million at September 30, 2011 and December 31, 2010, respectively. Primarily as a result of our $1.1 billion debt offering in February 2011 and an increase in net borrowings on our credit facilities during the Current Period of $675 million, total debt as a percentage of total debt plus equity increased to 32 percent at September 30, 2011 from 28 percent at December 31, 2010. Additionally, at September 30, 2011, we had a total contract drilling services backlog of approximately $12.8 billion. Our backlog as of September 30, 2011 reflects a commitment of 81 percent of operating days for the remainder of 2011 and 53 percent for 2012. See additional information regarding our backlog at “Contract Drilling Services Backlog.”

Our principal capital resource in the Current Period was cash generated from our $1.1 billion senior notes offering, net borrowings under our bank credit facilities of $675 million and net cash from operating activities of $474 million.

Our currently anticipated cash flow needs include the following:

	•		normal recurring operating expenses;

	•		committed capital expenditures, including expenditures for newbuild projects currently underway;

	•		discretionary capital expenditures, including various capital upgrades; and

	•		payments of return of capital in the form of a reduction of par value of our shares (in lieu of dividends).

We currently expect to fund these cash flow needs with cash generated by our operations, cash on hand and borrowings under our existing bank credit facilities. However, given the level of expenditures we expect to incur through the end of 2012, a significant portion of which relates to our newbuild program, we may require capital in excess of the amount provided through these sources. Subject to market and other conditions, we may raise such additional capital in a number of ways, including accessing capital markets, obtaining additional lines of credit or disposing of assets. We also retain the flexibility to delay or cancel certain discretionary capital expenditures as necessary.

Capital Expenditures

Our primary liquidity requirement during 2011 is for capital expenditures. Capital expenditures, including capitalized interest, totaled $2.0 billion and $886 million for the nine months ended September 30, 2011 and 2010, respectively. Capital expenditures for 2010 do not include the fair value of assets acquired as part of the Frontier acquisition.

At September 30, 2011, we had 13 rigs under construction, and capital expenditures for new construction during the first nine months of 2011 totaled $1.3 billion, as follows (in millions):

Total Newbuild Capital Expenditures	$	1,280.6

In addition to the newbuild expenditures noted above, capital expenditures during 2011 consisted of:

•

$463 million for major projects, including $130 million to upgrade two drillships currently operating in Brazil;

•

$156 million for other capitalized expenditures, including major maintenance and regulatory expenditures which generally have useful lives ranging from 3 to 5 years; and

•

$88 million in capitalized interest.

Our total capital expenditure estimate for 2011 is approximately $2.7 billion. In connection with our 2011 and future capital expenditure programs, as of September 30, 2011, we had outstanding commitments, including shipyard and purchase commitments, for approximately $3.4 billion, of which $1.1 billion is anticipated to be spent within the next twelve months. Our remaining 2011 capital expenditure budget and our 2012 capital expenditures will generally be spent at our discretion. We may accelerate or delay capital projects as needed.

From time to time we consider possible projects that would require expenditures that are not included in our capital budget, and such unbudgeted expenditures could be significant. In addition, we will continue to evaluate acquisitions of drilling units from time to time. Other factors that could cause actual capital expenditures to materially exceed plan include delays and cost overruns in shipyards (including costs attributable to labor shortages), shortages of equipment, latent damage or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions, changes in governmental regulations and requirements and changes in design criteria or specifications during repair or construction.

Share Repurchases and Dividends

At September 30, 2011, 6.8 million registered shares remained available under the existing Board authorization for our share repurchase program. No shares have been repurchased under this authorization during the nine months ended September 30, 2011. During the nine months ended September 30, 2011, we acquired approximately 0.3 million shares surrendered by employees for taxes payable upon the vesting of restricted stock and exercises of options for $10 million. Future repurchases by Noble-Swiss will be subject to the requirements of Swiss law, including the requirement that Noble-Swiss and its subsidiaries may only repurchase shares if and to the extent that sufficient freely distributable reserves are available.

In April 2011, our shareholders approved the payment of a return of capital through a reduction of the par value of our shares in a total amount equal to 0.52 CHF per share to be paid in four equal installments scheduled for August 2011, November 2011, February 2012 and May 2012. The payments will be made in U.S. Dollars based on the CHF/USD exchange rate available approximately two business days prior to the payment date. Although the amount of the return of capital, expressed in Swiss francs, is fixed, the amount of the payment in U.S. Dollars will fluctuate based on the exchange rate. The exchange rate as published by the Swiss National Bank on October 28, 2011 was 0.8625 CHF/1.0 USD. These returns of capital will require us to make total cash payments of approximately $38 million during the remainder of 2011 (based on the exchange rate on October 28, 2011).

Our most recent quarterly payment to shareholders in the form of a capital reduction, which was paid on August 18, 2011 to holders of record on August 8, 2011, was 0.13 CHF per share, or an aggregate of approximately $42 million. The declaration and payment of dividends in the future by Noble-Swiss and the making of distributions of capital, including returns of capital in the form of par value or additional paid-in capital reductions, require authorization of the shareholders of Noble-Swiss. The amount of such dividends, distributions and returns of capital will depend on our results of operations, financial condition, cash requirements, future business prospects, contractual restrictions and other factors deemed relevant by our Board of Directors and shareholders.

Credit Facilities and Long-Term Debt

The Credit Facilities provide us with the ability to issue up to $300 million in letters of credit in the aggregate. While the issuance of letters of credit does not increase our borrowings outstanding under the Credit Facilities, it does reduce the amount available. At September 30, 2011, we had borrowings of $715 million outstanding and no letters of credit outstanding under the Credit Facilities. We believe that we maintain good relationships with our lenders under the Credit Facilities, and we believe that our lenders have the liquidity and capability to perform should the need arise for us to draw on the Credit Facilities.

The indentures governing our outstanding senior unsecured notes contain covenants that place restrictions on certain merger and consolidation transactions, unless we are the surviving entity or the other party assumes the obligations under the indenture, and on the ability to sell or transfer all or substantially all of our assets. In addition, there are restrictions on incurring or assuming certain liens and sale and lease-back transactions. At September 30, 2011, we were in compliance with all our debt covenants. We continually monitor compliance with the covenants under our Credit Facilities and senior notes and, based on our expectations for 2011, expect to remain in compliance during the year.

At September 30, 2011, we had letters of credit of $74 million and performance and tax assessment bonds totaling $295 million supported by surety bonds outstanding. Additionally, certain of our subsidiaries issue, from time to time, guarantees of the temporary import status of rigs or equipment imported into certain countries in which we operate. These guarantees are issued in lieu of payment of custom, value added or similar taxes in those countries.

Our long-term debt, including current maturities, was $3.8 billion at September 30, 2011 as compared to $2.8 billion at December 31, 2010. The increase in debt is a result of the issuance of $1.1 billion aggregate principal amount of senior notes and $675 million of additional net borrowings on our Credit Facilities, partially offset by the repayment of $693 million in joint venture credit facilities. For additional information on our long-term debt, see Note 8 to our consolidated financial statements.

In April 2011, the Bully joint venture partners entered into a subscription agreement, pursuant to which each partner was issued equity in each of the Bully joint ventures in exchange for the cancellation of all outstanding joint venture partner notes. The subscription agreement has the effect of converting all joint venture partner notes, including the contribution noted above, into equity of the respective joint venture. The total capital contributed as a result of these agreements was $146 million, which included $142 million in outstanding notes, plus accrued interest. Our portion of the capital contribution, totaling $73 million, was eliminated in consolidation.

New Accounting Pronouncements

In May 2011, the FASB issued guidance that modified the wording used to describe many of the requirements in accounting literature for measuring fair value and for disclosing information about fair value measurements. The goal of the amendment is to create consistency between the United States and international accounting standards. The guidance is effective for annual and interim reporting periods beginning on or after December 15, 2011. While we are still evaluating this guidance, the adoption of this guidance is not expected to have a material impact on our financial condition, results of operations, cash flows or financial disclosures.

In June 2011, the FASB issued guidance that allows an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendment no longer allows an entity to show changes to other comprehensive income solely through the statement of equity. For publicly traded entities, the guidance is effective for annual and interim reporting periods beginning on or after December 15, 2011. While we are still evaluating this guidance, the adoption of this guidance is not expected to have a material impact on our financial condition, results of operations, cash flows or financial disclosures.


Item 3.		Quantitative and Qualitative Disclosures About Market Risk

Market risk is the potential for loss from a change in the value of a financial instrument as a result of fluctuations in interest rates, currency exchange rates or equity prices, as further described below.

Interest Rate Risk

We are subject to market risk exposure related to changes in interest rates on borrowings under the Credit Facilities. Interest on borrowings under the Credit Facilities is at an agreed upon percentage point spread over LIBOR, or a base rate stated in the agreements. At September 30, 2011, we had $715 million outstanding under the Credit Facilities. Assuming our current level of debt, a change in LIBOR rates of one percent would increase our interest charges by approximately $7 million per year.

We maintain certain debt instruments at a fixed rate whose fair value will fluctuate based on changes in interest rates and market perceptions of our credit risk. The fair value of our total debt was $3.4 billion and $2.9 billion at September 30, 2011 and December 31, 2010, respectively. The increase was primarily a result of our issuance of $1.1 billion in debt in February 2011 and $675 million of additional net borrowings on the Credit Facilities, partially offset by the repayment of $693 million in joint venture credit facilities coupled with changes in fair value related to changes in interest rates and market perceptions of our credit risk.

Foreign Currency Risk

As a multinational company, we conduct business worldwide. Our functional currency is primarily the U.S. dollar, which is consistent with the oil and gas industry. However, outside the United States, a portion of our expenses are incurred in local currencies. Therefore, when the U.S. dollar weakens (strengthens) in relation to the currencies of the countries in which we operate, our expenses reported in U.S. dollars will increase (decrease).

We are exposed to risks on future cash flows to the extent that local currency expenses exceed revenues denominated in local currency that are different than the functional currency. To help manage this potential risk, we periodically enter into derivative instruments to manage our exposure to fluctuations in currency exchange rates, and we may conduct hedging activities in future periods to mitigate such exposure. These contracts are primarily accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Consolidated Balance Sheet and in “Accumulated other comprehensive loss” (“AOCL”). Amounts recorded in AOCL are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of the hedged item is recorded directly to earnings. We have documented policies and procedures to monitor and control the use of derivative instruments. We do not engage in derivative transactions for speculative or trading purposes, nor are we a party to leveraged derivatives.

Our North Sea and Brazil operations have a significant amount of their cash operating expenses payable in local currencies. To limit the potential risk of currency fluctuations, we typically maintain short-term forward contracts settling monthly in their respective local currencies. The forward contract settlements in the remainder of 2011 represent approximately 43 percent of these forecasted local currency requirements. The notional amount of the forward contracts outstanding, expressed in U.S. dollars, was approximately $71 million at September 30, 2011. Total unrealized losses related to these forward contracts were $6 million as of September 30, 2011 and were recorded as part of AOCL. A 10 percent change in the exchange rate for the local currencies would change the fair value of these forward contracts by approximately $7 million.

Market Risk

We sponsor the Noble Drilling Corporation 401(k) Savings Restoration Plan (“Restoration Plan”). The Restoration Plan is a nonqualified, unfunded employee benefit plan under which certain highly compensated employees may elect to defer compensation in excess of amounts deferrable under our 401(k) savings plan. The Restoration Plan has no assets, and amounts withheld for the Restoration Plan are kept by us for general corporate purposes. The investments selected by employees and the associated returns are tracked on a phantom basis. Accordingly, we have a liability to employees for amounts originally withheld plus phantom investment income or less phantom investment losses. We are at risk for phantom investment income and, conversely, benefit should phantom investment losses occur. At September 30, 2011, our liability under the Restoration Plan totaled $5 million. We previously purchased investments that closely correlate to the investment elections made by participants in the Restoration Plan in order to mitigate the impact of the phantom investment income and losses on our consolidated financial statements. The value of these investments held for our benefit totaled $4 million at September 30, 2011. A 10 percent change in the fair value of the phantom investments would change our liability by approximately $0.4 million. Any change in the fair value of the phantom investments would be mitigated by a change in the investments held for our benefit.

We also have a U.S. noncontributory defined benefit pension plan that covers certain salaried employees and a U.S. noncontributory defined benefit pension plan that covers certain hourly employees, whose initial date of employment is prior to August 1, 2004 (collectively referred to as our “qualified U.S. plans”). These plans are governed by the Noble Drilling Corporation Retirement Trust. The benefits from these plans are based primarily on years of service and, for the salaried plan, employees’ compensation near retirement. These plans are designed to qualify under the Employee Retirement Income Security Act of 1974 (“ERISA”), and our funding policy is consistent with funding requirements of ERISA and other applicable laws and regulations. We make cash contributions, or utilize credits available to us, for the qualified U.S. plans when required. The benefit amount that can be covered by the qualified U.S. plans is limited under ERISA and the Internal Revenue Code (“IRC”) of 1986. Therefore, we maintain an unfunded, nonqualified excess benefit plan designed to maintain benefits for all employees at the formula level in the qualified U.S. plans.

In addition to the U.S. plans, each of Noble Drilling (Land Support) Limited, Noble Enterprises Limited and Noble Drilling (Nederland) B.V., all indirect, wholly-owned subsidiaries of Noble-Swiss, maintains a pension plan that covers all of its salaried, non-union employees (collectively referred to as our “non-U.S. plans”). Benefits are based on credited service and employees’ compensation near retirement, as defined by the plans.

Changes in market asset values related to the pension plans noted above could have a material impact upon our “Consolidated Statement of Comprehensive Income” and could result in material cash expenditures in future periods.


Item 4.		Controls and Procedures

David W. Williams, Chairman, President and Chief Executive Officer of Noble-Swiss, and Dennis J. Lubojacky, Principal Financial Officer and Principal Accounting Officer of Noble-Swiss, have evaluated the disclosure controls and procedures of Noble-Swiss as of the end of the period covered by this report. On the basis of this evaluation, Mr. Williams and Mr. Lubojacky have concluded that Noble-Swiss’ disclosure controls and procedures were effective as of September 30, 2011. Noble-Swiss’ disclosure controls and procedures are designed to ensure that information required to be disclosed by Noble-Swiss in the reports that it files with or submits to the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosure.

David W. Williams, President and Chief Executive Officer of Noble-Cayman, and Dennis J. Lubojacky, Vice President and Chief Financial Officer of Noble-Cayman, have evaluated the disclosure controls and procedures of Noble-Cayman as of the end of the period covered by this report. On the basis of this evaluation, Mr. Williams and Mr. Lubojacky have concluded that Noble-Cayman’s disclosure controls and procedures were effective as of September 30, 2011. Noble-Cayman’s disclosure controls and procedures are designed to ensure that information required to be disclosed by Noble-Cayman in the reports that it files with or submits to the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosure.

There was no change in either Noble-Swiss’ or Noble-Cayman’s internal control over financial reporting that occurred during the quarter ended September 30, 2011 that has materially affected, or is reasonably likely to materially affect, the internal control over financial reporting of each of Noble-Swiss or Noble-Cayman, respectively.

PART II. OTHER INFORMATION


Item 1.		Legal Proceedings

Information regarding legal proceedings is set forth in Note 13 to our consolidated financial statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q and is incorporated herein by reference.


Item 1A.		Risk Factors

Risks Relating to Our Business

The risk factor below updates and supplements the risks described under “Risk Factors Relating to Our Business” in Part I, Item 1A, “Risk Factors,” of our Annual Report on Form 10-K for the year ended December 31, 2010, and should be considered together with the risk factors described in that report.

We may have difficulty obtaining or maintaining insurance in the future and our insurance coverage and contractual indemnity rights may not protect us against all of the risks and hazards we face.

We generally identify the operational hazards for which we will procure insurance coverage based on the likelihood of loss, the potential magnitude of loss, the cost of coverage, the requirements of our customer contracts and applicable legal requirements. We do not procure insurance coverage for all of the potential risks and hazards we may face. Furthermore, no assurance can be given that we will be able to obtain insurance against all of the risks and hazards we face or that we will be able to obtain or maintain adequate insurance at rates and with deductibles or retention amounts that we consider commercially reasonable.

Although we maintain what we believe to be an appropriate level of insurance covering hazards and risks we currently encounter during our operations, we do not insure against all possible hazards and risks. Furthermore, our insurance carriers may interpret our insurance policies such that they do not cover losses for which we make claims. Our insurance policies may also have exclusions of coverage for some losses. Uninsured exposures may include expatriate activities prohibited by U.S. laws, radiation hazards, certain loss or damage to property onboard our rigs and losses relating to shore-based terrorist acts or strikes.

In addition, the damage sustained to offshore oil and gas assets as a result of hurricanes in recent years caused the insurance market for U.S. named windstorm perils to deteriorate significantly. Consequently, we currently self-insure U.S. named windstorm coverage for our units deployed in the U.S. Gulf of Mexico. If one or more future significant weather-related events occur in the Gulf of Mexico, or in any other geographic area in which we operate, we may experience increases in insurance costs, additional coverage restrictions or unavailability of certain insurance products.

Under our drilling contracts, liability with respect to personnel and property is customarily assigned on a “knock-for-knock” basis, which means that we and our customers assume liability for our respective personnel and property, irrespective of the fault or negligence of the party indemnified. Although our drilling contracts generally provide for indemnification from our customers for certain liabilities, including liabilities resulting from pollution or contamination originating below the surface of the water, enforcement of these contractual rights to indemnity may be limited by public policy and other considerations and, in any event, may not adequately cover our losses from such incidents. There can also be no assurance that those parties with contractual obligations to indemnify us will necessarily be in a financial position to do so.

If a significant accident or other event occurs and is not fully covered by our insurance or a contractual indemnity, it could materially adversely affect our financial position, results of operations or cash flows.

As a result of our significant cash flow needs, we may be required to incur additional indebtedness, or delay or cancel discretionary capital expenditures.

Our currently anticipated cash flow needs include the following:

•

normal recurring operating expenses;

•

committed capital expenditures, including expenditures for newbuild projects currently underway;

•

discretionary capital expenditures, including various capital upgrades; and

•

payments of return of capital in the form of a reduction of par value of our shares (in lieu of dividends).

In order to fund our capital expenditures, we may need funding beyond the amount available to us from cash generated by our operations, cash on hand and borrowings under our existing bank credit facilities. We may raise such additional capital in a number of ways, including accessing capital markets, obtaining additional lines of credit or disposing of assets. However, we can provide no assurance that any of these options will be available to us on terms acceptable to us or at all.

Our ability to obtain financing or to access the capital markets may be limited by our financial condition at the time of any such financing and the covenants in our existing debt agreements, as well as by adverse market conditions resulting from, among other things, general economic conditions and uncertainties that are beyond our control. Even if we are successful in obtaining additional capital through debt financings, incurring additional indebtedness may significantly increase our interest expense and may reduce our flexibility to respond to changing business and economic conditions or to fund working capital needs, because we will require additional funds to service our outstanding indebtedness.

If we fail to obtain the capital necessary to fund our capital expenditures, we may delay or cancel discretionary capital expenditures, which could have certain adverse consequences including delaying upgrades or equipment purchases that could make the affected rigs less competitive and negatively affect our ability to contract such rigs.
