(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts.)
NOTE 1 — BASIS OF PRESENTATION
     The accompanying unaudited condensed consolidated financial statements of Noble Corporation (“Noble” or, together with its consolidated subsidiaries, unless the context requires otherwise, the “Company”, “we”, “our” and words of similar import) 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 note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America 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 presentation 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 Consolidated Balance Sheet at December 31, 2007 presented herein is derived from the December 31, 2007 audited consolidated financial statements. These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2007. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.
     On July 27, 2007, Noble’s board of directors approved what is commonly referred to in the United States as a “two-for-one stock split” of Noble’s ordinary shares effected in the form of a 100 percent stock dividend to members (shareholders) of record on August 7, 2007. The stock dividend was distributed on August 28, 2007 when shareholders of record were issued one additional ordinary share for each ordinary share held. All share and per share data included in the unaudited condensed consolidated financial statements and accompanying notes have been adjusted to reflect the stock split for all periods presented.
     Certain prior-period amounts have been reclassified to conform with the current year presentation.
NOTE 2 — NET INCOME PER SHARE
     The following table reconciles the basic and diluted average shares outstanding for net income per share computations (shares in thousands):
                 
    Three Months Ended

Net income per share:
               
Basic
  $ 1.44     $ 0.94  
Diluted
  $ 1.43     $ 0.93  
     For the periods presented, there were no adjustments to net income for purposes of calculating basic or diluted net income per share. The computation of diluted net income per share for the three-month periods ended March 31, 2008 and 2007 does not include stock options and restricted stock totaling 181,338 and 1,701,856 shares, respectively, because they were anti-dilutive.

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts.)
NOTE 3 — PROPERTY AND EQUIPMENT
     Interest is capitalized on construction-in-progress at the weighted average cost of debt outstanding during the period of construction. Capitalized interest for each of the three-month periods ended March 31, 2008 and 2007 was $12 million.
     Certain of our rigs operating in the U.S. Gulf of Mexico sustained damage in 2005 as a result of Hurricanes Katrina and Rita. All damaged rigs returned to work by April 2006. Our insurance receivables at December 31, 2007 relating to claims for hurricane damage were $39 million. During the first quarter of 2008, we received $39 million as final settlement of all remaining hurricane-related claims and receivables for physical damage and loss of hire.
NOTE 4 — DEBT
     Noble entered into an unsecured revolving bank credit facility in 2007 totaling $600 million (the “Bank Credit Agreement”), which has an initial term of five years. In the first quarter of 2008, the term of the Bank Credit Agreement was extended for an additional one-year period, from March 15, 2012 to March 15, 2013. During this one-year extension, the total amount available under the Bank Credit Agreement will be $575 million, with Noble retaining the right to seek an increase of the total amount available to $600 million through existing lenders under the Bank Credit Agreement or new lenders. Noble may, subject to certain conditions, request that the term of the Bank Credit Agreement be further extended for an additional one-year period. Noble Drilling Corporation (“Noble Drilling”) has issued a guaranty of the obligations under the Bank Credit Agreement. Pursuant to the terms of the Bank Credit Agreement, Noble may, subject to certain conditions, elect to increase the maximum amount available under the Bank Credit Agreement to an amount not to exceed $800 million. At March 31, 2008, we had $50 million in borrowings and $132 million in letters of credit outstanding under the Bank Credit Agreement, leaving $418 million remaining available thereunder. The weighted average interest rate for outstanding borrowings under the Bank Credit Agreement was 3.06 percent at March 31, 2008.
NOTE 5 — INCOME TAXES
     At December 31, 2007, the reserves for uncertain tax positions totaled $61 million (net of related tax benefits of $7 million). At March 31, 2008, the reserves for uncertain tax positions remained at $61 million (net of related tax benefits of $4 million). If these reserves of $61 million are not realized, the provision for income taxes would be reduced by $35 million and equity would be directly increased by $26 million.
     We do not anticipate that any tax contingencies resolved in the next 12 months will have a material impact on our consolidated financial position or results of operations.

Net pension expense
  $ 1,062     $ 1,147     $ 1,267     $ 1,989  
 
                       
     In August 2006, U.S. President Bush signed into law the Pension Protection Act of 2006 (“PPA”). The PPA requires that pension plans become fully funded over a seven-year period beginning in 2008 and increases the amount we are allowed to contribute to our domestic pension plans in the near term.
     During the three months ended March 31, 2008, we made contributions to our pension plans totaling $3 million. We expect to contribute, subject to applicable law, an aggregate of $9 million to our pension plans in 2008, which includes the $3 million in contributions made during the three months ended March 31, 2008.
     We sponsor the Noble Drilling Corporation 401(k) Savings Restoration Plan (“Restoration Plan”). The Restoration Plan has no assets, and amounts “contributed” to the Restoration Plan are kept by us for general corporate purposes. The investments selected by employees and associated returns are tracked on a phantom basis. Accordingly, we have a liability to employees for amounts originally contributed 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 March 31, 2008, our liability under the Restoration Plan totaled $13 million.
NOTE 7 — DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
     We periodically enter into derivative instruments to manage our cash flow exposure to fluctuations in interest rates and foreign currency exchange rates, and we may conduct hedging activities in future periods to mitigate such exposure. 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 operations have a significant amount of their cash operating expenses payable in either the Euro or British Pound, and we maintain forward currency contracts settling monthly in Euro and British Pounds. The Euro-denominated forward contracts settling in the remainder of 2008 represent approximately 40 percent of our forecasted Euro requirements. The British Pound-denominated forward contracts settling in the remainder of 2008 represent approximately 19 percent of our forecasted British Pound requirements. The notional amount of forward contracts outstanding at March 31, 2008 was approximately 8 million Euros and 5 million British Pounds. The aggregate notional amount of these forward contracts, expressed in U.S. Dollars, was $21 million at March 31, 2008.
     All of the above foreign currency forward contracts were accounted for as cash flow hedges under Statement of Financial Accounting Standards (“SFAS”) No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended (“SFAS No. 133”). The fair market value of those derivative instruments is included in Other current assets or Other current liabilities with the cumulative unrealized gain or loss included in Accumulated Other Comprehensive Loss in our Consolidated Balance Sheets. The fair market value of outstanding foreign currency forward contracts was $2 million at March 31, 2008. Hedge effectiveness is measured quarterly based on the relative cumulative changes in fair value between derivative contracts and the hedge item over time. Any change in fair value resulting from ineffectiveness is recognized immediately in earnings. We did not

NOTE 8 — FAIR VALUE OF FINANCIAL INSTRUMENTS
     In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 157, Fair Value Measurements (“SFAS No. 157”). SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements. Instead, its application will be made pursuant to other accounting pronouncements that require or permit fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. On February 6, 2008, the FASB issued FASB Staff Position FAS 157-2, Partial Deferral of the Effective Date of Statement 157, which deferred the effective date for one year for certain nonfinancial assets and liabilities, except those recognized or disclosed at fair value on a recurring basis. These nonfinancial items include reporting units measured at fair value in a goodwill impairment test and nonfinancial assets and liabilities assumed in a business combination.
     We adopted SFAS No. 157 effective January 1, 2008 for financial assets and liabilities measured on a recurring basis. There was no impact for the partial adoption of SFAS No. 157 on our consolidated financial statements. We do not expect the application of SFAS No. 157 to our nonfinancial assets and liabilities to have any material effect on our consolidated financial statements.
     The following table presents the carrying amount and estimated fair value of our financial instruments recognized at fair value on a recurring basis:

     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.
     In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Liabilities (“SFAS No. 159”). SFAS No. 159 permits entities to measure eligible assets and liabilities at fair value.

We adopted SFAS No. 159 effective January 1, 2008, and we did not elect the fair value option for our financial instruments. Accordingly, there was no impact to our consolidated financial statements as a result of this adoption.
NOTE 9 — COMMITMENTS AND CONTINGENCIES
     Noble Asset Company Limited (“NACL”), a wholly-owned, indirect subsidiary of Noble, was named one of 21 parties served a Show Cause Notice (“SCN”) issued by the Commissioner of Customs (Prev.), Mumbai, India (the “Commissioner”) in August 2003. The SCN concerned alleged violations of Indian customs laws and regulations regarding one of our jackups. The Commissioner alleged certain violations to have occurred before, at the time of, and after NACL acquired the rig from the rig’s previous owner. In the purchase agreement for the rig, NACL received contractual indemnification against liability for Indian customs duty from the rig’s previous owner. In connection with the export of the rig from India in 2001, NACL posted a bank guarantee in the amount of $4 million and a customs bond in the amount of $24 million, both of which remain in place. In March 2005, the Commissioner passed an order against NACL and the other parties cited in the SCN seeking (i) to invoke the bank guarantee posted on behalf of NACL as a fine, (ii) to demand duty of (a) $19 million plus interest related to a 1997 alleged import and (b) $22 million plus interest related to a 1999 alleged import, provided that the duty and interest demanded in (b) would not be payable if the duty and interest demanded in (a) were paid by NACL, and (iii) to assess a penalty of $500,000 against NACL. NACL appealed the order of the Commissioner to the Customs, Excise & Service Tax Appellate Tribunal (“CESTAT”). At a hearing on April 5, 2006, CESTAT upheld NACL’s appeal and overturned the Commissioner’s March 2005 order against NACL in its entirety. CESTAT thereafter issued its written judgment dated August 8, 2006 upholding NACL’s appeal on all grounds and setting aside the duty demand, interest, fine and penalty. The Commissioner filed an appeal in the Bombay High Court challenging the order passed by CESTAT. In April 2007, the Division Bench of the Bombay High Court ruled that the Commissioner’s appeal is maintainable and ordered that for the time being the customs bond and the bank guarantee should continue to remain in place. The appeal hearing in the Bombay High Court concluded in February 2008, and to date, the Division Bench of the Bombay High Court has not delivered its order. NACL continues to pursue contractual indemnification against liability for Indian customs duty and related costs and expenses against the rig’s previous owner in arbitration proceedings in London, which proceedings the parties have temporarily stayed pending further developments in the Indian proceeding. We do not believe the ultimate resolution of this matter will have a material adverse effect on our financial position, results of operations or cash flows.
     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. We are currently contesting several 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. See Note 5 for additional information.
     Certain of our international income tax returns have been examined for the 2002 through 2004 periods and audit claims have been assessed for approximately $104 million (including interest and penalties). We believe audit claims of an additional $22 million to $24 million attributable to other business tax returns may be assessed against us. We have contested, or intend to contest, most of 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 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 claims under the Jones Act, purportedly resulting from exposure to asbestos on drilling rigs and associated facilities. At April 30, 2008, there were approximately 38 of these lawsuits in which we are one of many defendants, two of which are scheduled for trial in 2008. These lawsuits have been filed in the states of Louisiana, Mississippi and Texas. Exposure related to these lawsuits is not currently determinable. We intend to defend vigorously against the litigation.
     We are a defendant in certain claims and litigation arising out of operations in the ordinary course of business, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations or cash flows.

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts.)
     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 letters 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. On January 24, 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. NIMASA and the Minister of Transportation have filed a preliminary objection to our originating summons and the proceeding, which objection is scheduled for a hearing in May 2008. We intend to oppose the preliminary objection and 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.
     We maintain certain insurance coverage against specified marine liabilities, including liability for physical damage to our drilling rigs, and loss of hire on certain of our rigs. Our March 2008 insurance program renewal included an annual aggregate coverage limit of $200 million applicable to our drilling units operating in the U.S. Gulf of Mexico for physical damage and loss of hire on certain units resulting from named windstorm perils. This aggregate coverage limit may not fully insure our losses in the event that one or more named windstorms damage our drilling units in the U.S. Gulf of Mexico. The reduced coverage does not apply to our units in the Mexican portion of the Gulf of Mexico. We presently have six semisubmersibles and three submersibles in the U.S. Gulf. We maintained a $10 million deductible on our marine hull and machinery coverage, and loss of hire coverage is subject to a 60 day waiting period deductible for named U.S. Gulf windstorms and a 45 day waiting period for all other perils. 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 further increases in insurance costs, additional coverage restrictions or unavailability of certain insurance products.
     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. Since February 2004, our protection and indemnity policy has had a standard deductible of $1 million per occurrence, and we retain $5 million of claims in the aggregate beyond the standard deductible.
     Our capital expenditures and major maintenance expenditures for 2008 are budgeted at approximately $1.45 billion. In connection with our 2008 and future capital expenditure programs, we had entered into certain commitments, including shipyard and purchase commitments, of approximately $734 million at March 31, 2008.
Internal Investigation
     In June 2007, we announced that we were conducting an internal investigation of our Nigerian operations, focusing on the legality under the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”), and local laws of our Nigerian affiliate’s reimbursement of certain expenses incurred by our customs agents in connection with obtaining and renewing permits for the temporary importation of drilling units and related equipment into Nigerian waters, including permits that are necessary for our drilling units to operate in Nigerian waters. We also announced that the audit committee of Noble’s board of directors had engaged a leading law firm with significant experience in investigating and advising on FCPA matters to lead the investigation as independent outside counsel. The scope of the investigation also includes our dealings with customs agents and customs authorities in certain parts of the world other than Nigeria in which we conduct our operations, as well as dealings with other types of local agents in Nigeria and these other parts of the world. There can be no assurance that evidence of additional potential FCPA violations may not be uncovered through the investigation.

(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts.)
     The audit committee commissioned the internal investigation after our management brought to the attention of the audit committee a news release issued by another company that disclosed that the other company was conducting an internal investigation into the FCPA implications of certain actions by a customs agent in Nigeria in connection with the temporary importation of that company’s vessels into Nigeria. Our drilling units that conduct operations in Nigeria do so under temporary import permits, and management considered it prudent to review our own practices in this regard.
     We voluntarily contacted the SEC and the U.S. Department of Justice (“DOJ”) to advise them that an independent investigation was under way. We have been cooperating, and intend to continue to cooperate, fully with both agencies. If the SEC or the DOJ determines that violations of the FCPA have occurred, they could seek civil and criminal sanctions, including monetary penalties, against us and/or certain of our employees, as well as additional changes to our business practices and compliance programs, any of which could have a material adverse effect on our business and financial condition. In addition, such actions, whether actual or alleged, could damage our reputation and ability to do business, to attract and retain employees, and to access capital markets. Further, detecting, investigating, and resolving such actions is expensive and consumes significant time and attention of our senior management.
     The internal investigation is ongoing, and we cannot predict whether either the SEC or the DOJ will open its own proceeding to investigate this matter, or if a proceeding is opened, what potential remedies these agencies may seek. We could also face fines or sanctions in relevant foreign jurisdictions. Based on information obtained to date in our internal investigation, we have not determined that any potential liability that may result is either probable or can be reasonably estimated. As a result, we have not made any accrual in our financial statements at March 31, 2008.
     We are currently operating four jackup rigs offshore Nigeria, each of which has a temporary import permit through May 27, 2008. We recently filed with the Nigerian Customs Service applications for extensions of the temporary import permits for each of these rigs. Our management continues to seek to avoid material disruption to our Nigerian operations; however, there can be no assurance that we will be able to obtain further extensions necessary to continue operations of our rigs in Nigeria after expiration of the current term of the temporary import permits. If we cannot obtain a further extension necessary to continue operations of any rig, we may need to terminate the drilling contract of such rig and relocate such rig from Nigerian waters. 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.
     Notwithstanding that the internal investigation is ongoing, we have concluded that certain changes to our FCPA compliance program would provide us greater assurance that our assets are not used, directly or indirectly, to make improper payments, including customs payments, and that we are in compliance with the FCPA’s record-keeping requirements. Although we have had a long-standing published policy requiring compliance with the FCPA and broadly prohibiting any improper payments by us to foreign or domestic officials, we have since the commencement of the internal investigation adopted, and may adopt additional, intermediate measures intended to enhance FCPA compliance procedures. Additional measures may be required once the investigation concludes.
     For the three months ended March 31, 2008, we incurred legal fees and related costs of $7 million related to the internal investigation. It is anticipated that additional costs will be incurred in future periods, but the amount of these costs cannot be presently determined.
NOTE 10 — SEGMENT AND RELATED INFORMATION
     Effective in the fourth quarter of 2007, we report our international and domestic contract drilling operations as a single reportable segment: Contract Drilling Services. The consolidation into one reportable segment was attributable to how we manage our business, and the fact that all of our drilling fleet is dependent upon the worldwide oil 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 due to changing demands of our customers, which consist largely of major international and government owned/controlled oil and gas companies throughout the world. Our contract drilling services segment conducts contract drilling operations in the Middle East, India, U.S. Gulf of Mexico, Mexico, the North Sea, Brazil and West Africa.

NOTE 11 — ACCOUNTING PRONOUNCEMENTS
     In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements — An Amendment of ARB No. 51 (“SFAS No. 160”). SFAS No. 160 establishes new accounting and reporting standards for a noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. Specifically, this statement requires the recognition of a noncontrolling interest (minority interest) as equity in the consolidated financial statements. The amount of net income attributable to a noncontrolling interest will be included in consolidated net income on the face of the income statement. SFAS No. 160 requires that changes in a parent’s ownership interest in a subsidiary that do not result in deconsolidation are equity transactions if the parent retains its controlling financial interest. In addition, this statement requires that a parent recognize a gain or loss when a subsidiary is deconsolidated. Such gain or loss will be measured using the fair value of the noncontrolling equity investment on the deconsolidation date. SFAS No. 160 also includes expanded disclosures regarding the interests of the parent and its noncontrolling interest. SFAS No. 160 is effective for fiscal years beginning on or after December 15, 2008 and earlier adoption is prohibited. We do not expect the adoption of SFAS No. 160 to have a material impact on our financial position or results of operations.
     In December 2007, the FASB issued SFAS No. 141R, Business Combinations (“SFAS No. 141R”). SFAS No. 141R will significantly change the accounting for business combinations. Under SFAS No. 141R, the acquiring entity will be required to recognize all the assets acquired and liabilities assumed in a transaction at the acquisition-date fair value with limited exceptions. SFAS No. 141R will change the accounting treatment for certain specific items, including:

15


Table of Contents

NOBLE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands, except per share amounts.)
    transaction costs will generally be expensed as incurred;
 
    contingent consideration will be recognized at fair value on the acquisition date;
 
    acquired contingent liabilities will be recorded at fair value at the acquisition date and subsequently measured at either the higher of such amount or the amount determined under existing guidance for non-acquired contingencies;
 
    fair value of the purchase price, including the issuance of equity securities, will be determined on the acquisition date (closing) instead of announcement date;
 
    restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and
 
    changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense.
     SFAS No. 141R applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008, and earlier adoption is prohibited. This standard will change our accounting treatment for business combinations on a prospective basis.
     In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (“SFAS No. 161”). SFAS No. 161 requires entities with derivative instruments to disclose information to enable financial statement users to understand how and why the entity uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS No. 133 and how derivative instruments and related hedged items affect the entity’s financial position, financial performance and cash flows. SFAS No. 161 is effective for fiscal years and interim periods beginning after November 15, 2008. We are currently evaluating the impact, if any, that SFAS No. 161 will have on our consolidated financial statements.
NOTE 12 — SUBSEQUENT EVENT
     On April 8, 2008, we sold our North Sea labor contract drilling services business to Seawell Holding UK Limited (“Seawell”) for $35 million, pursuant to a previously-announced agreement. This sale included labor contracts covering 11 platform operations in the United Kingdom sector of the North Sea. These operations employed approximately 450 people and generated $25 million and $96 million of revenue in the three months ended March 31, 2008 and the year ended December 31, 2007, respectively.
     On April 16, 2008, Noble’s board of directors declared a special cash dividend of $0.75 per ordinary share payable to shareholders of record on April 30, 2008, with a distribution date of May 16, 2008. On April 30, 2008, Noble’s board of directors declared a quarterly cash dividend of $0.04 per ordinary share payable to shareholders of record on May 14, 2008, with a distribution date of May 30, 2008.
NOTE 13 — GUARANTEES OF REGISTERED SECURITIES
     Noble and Noble Holding (U.S.) Corporation (“NHC”), a wholly-owned subsidiary of Noble, are guarantors for certain debt securities issued by Noble Drilling. These debt securities consist of Noble Drilling’s 6.95% Senior Notes due 2009 and its 7.50% Senior Notes due 2019. The outstanding principal balances of the 6.95% Senior Notes and the 7.50% Senior Notes at March 31, 2008 were $150 million and $202 million, respectively. Noble Drilling is an indirect, wholly-owned subsidiary of Noble and a direct, wholly-owned subsidiary of NHC. Noble’s and NHC’s guarantees of the 6.95% Senior Notes and the 7.50% Senior Notes are full and unconditional. In December 2005, Noble Drilling Holding LLC (“NDH”), an indirect wholly-owned subsidiary of Noble, became a co-obligor on (and effectively a guarantor of) the 6.95% Senior Notes and the 7.50% Senior Notes.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
     The following discussion is intended to assist you in understanding our financial position at March 31, 2008, and our results of operations for the three months ended March 31, 2008 and 2007. The following discussion should be read in conjunction with the condensed consolidated financial statements and related notes contained in this report on Form 10-Q and the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2007.
     Effective in the fourth quarter of 2007, we report our international and domestic contract drilling operations as a single reportable segment: Contract Drilling Services. The consolidation into one reportable segment was attributable to how we manage our business, and the fact that all of our drilling fleet is dependent upon the worldwide oil 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 due to changing demands of our customers, which consist largely of major international and government owned/controlled oil and gas companies throughout the world. The “Other” category in our segment-based discussions includes the results of labor contract drilling services, engineering and consulting services, other insignificant operations and corporate related items. All prior year information has been reclassified to conform to the current year presentation of segments. See Note 10 of our Notes to Consolidated Financial Statements included in Item 1 of this Quarterly Report on Form 10-Q.
FORWARD-LOOKING STATEMENTS
     This report on Form 10-Q includes “forward-looking statements” within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended. All statements other than statements of historical facts included in this report regarding our financial position, business strategy, plans and objectives of management for future operations, industry conditions, and indebtedness covenant compliance are forward-looking statements. When used in this report, the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “should” and similar expressions are intended to be among the statements that identify forward-looking statements. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot assure you that such expectations will prove to have been correct. We have identified factors that could cause actual plans or results to differ materially from those included in any forward-looking statements. These factors include those referenced or described in “Item 1A. Risk Factors” of Part II included herein, and in our other filings with the U.S. Securities and Exchange Commission (“SEC”). Such risks and uncertainties are beyond our ability to control, 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
     We are a leading offshore drilling contractor for the oil and gas industry. We perform contract drilling services with our fleet of 62 offshore drilling units located worldwide, including the United States Gulf of Mexico, the Middle East, India, Mexico, the North Sea, Brazil, and West Africa.
     In the first quarter of 2008, we achieved our fifth consecutive quarter of record results with net income of $384 million, or $1.43 per fully diluted share, on total revenues of $861 million. The average dayrate across our worldwide fleet increased to $163,772 from $155,707 in the fourth quarter of 2007. Fleetwide average utilization also increased slightly to 94 percent from 93 percent quarter-on-quarter. Lower than anticipated contract drilling services costs were the major contributor to our increase in net income relative to our budget expectations driven by reduced spending on repairs and maintenance and cost control with respect to labor, shore base, and operations support costs. As a result, our contract drilling services margin increased to 70.4 percent from 68.0 percent in the fourth quarter of 2007. Sequentially, contract drilling services costs of $236 million were lower by $8 million from $244 million in the fourth quarter of 2007. However, fourth quarter 2007 costs included a $10 million charge related to a fire aboard the drillship Noble Roger Eason. Excluding this charge, the sequential cost increase was just under one percent. Daily contract drilling services costs, excluding the charge, increased one percent to $48,430 from $47,848.
     Our long-standing business strategy continues to be the active expansion of our worldwide offshore drilling and deepwater capabilities through acquisitions, upgrades and modifications, and the deployment of our drilling assets in important geological areas. We have also actively expanded our offshore drilling and deepwater

capabilities in recent years through the construction of new rigs. During the first quarter of 2008, we continued our active expansion strategy as indicated by the following activities:
    commenced operating the newbuild F&G JU-2000E enhanced premium independent leg cantilevered jackup Noble Roger Lewis following delivery acceptance in the fourth quarter of 2007. The unit is under contract with Shell in the Middle East at a dayrate of $105,000;
 
    continued construction on the three remaining newbuild ultra-deepwater semisubmersibles, the Noble Dave Beard, Noble Danny Adkins and Noble Jim Day, which are scheduled for delivery in the fourth quarter of 2008, the first quarter of 2009 and the fourth quarter of 2009, respectively; and
 
    continued construction on the two remaining F&G JU-2000E enhanced premium independent leg cantilevered jackups, the Noble Hans Deul and Noble Scott Marks, which are being constructed in China and are scheduled for delivery in the third quarter of 2008 and the second quarter of 2009, respectively.
     Newbuild capital expenditures totaled $134 million for our five rigs under construction during the first quarter of 2008.
     Additionally, during the quarter, we continued to refine our focus on the core business of contract drilling services. On January 16, 2008 we announced an agreement to sell our North Sea platform drilling business to Seawell Holding UK Limited for $35 million. Closing took place on April 8, 2008.
     Demand for drilling services 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 the various governments regarding exploration and development of their oil and gas reserves. Demand for our services is also a function of the worldwide supply of mobile offshore drilling units. A total of 70 newbuild jackups and 44 deepwater newbuilds are reportedly scheduled to enter service worldwide in 2008 and 2009. Many of these rigs have been built by market speculators, and while the majority of the deepwater rigs have already secured commitments, many of the jackups are currently uncontracted. The introduction of uncontracted rigs into the marketplace could have an adverse affect on the level of demand for our services or the dayrates we are able to achieve.
     Our results of operations depend on the levels of activity in offshore oil and gas exploration, development and production in markets 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 a greater demand for our services. These prices are extremely volatile. The average Brent oil price was $72.47 per barrel during 2007, or 11 percent higher than the average Brent oil price of $65.15 per barrel during 2006, following a 20 percent increase over 2005. The average Brent oil price increased further in the first quarter of 2008, averaging $96.94 per barrel.
     U.S. natural gas prices reached a 20-year high in 2005, averaging $8.81 per thousand cubic feet (average Henry Hub monthly spot price). Natural gas prices moderated during 2007 and 2006, averaging $6.98 and $6.74 per thousand cubic feet, respectively. During the first three months of 2008, natural gas prices have averaged $8.66 per thousand cubic feet, 20 percent higher than the $7.21 average price for the first quarter of 2007. We do not have significant exposure to the U.S. natural gas markets because we have only three mobile offshore drilling units (two contracted submersibles and one cold stacked submersible) currently deployed in the shallow waters of the U.S. Gulf of Mexico. However, the moderation of natural gas prices during 2007 and 2006 caused some competitors to move jackup rigs from the U.S. Gulf of Mexico market to various international markets, and these actions may increase competition within those markets.
     We cannot predict the future level of demand for our drilling services or future conditions in the offshore contract drilling industry. Decreases in the level of demand for our drilling services would have an adverse effect on our results of operations.

CONTRACT DRILLING SERVICES BACKLOG
     We maintain a backlog (as defined below) of commitments for contract drilling services. The following table sets forth as of March 31, 2008 the amount of our contract drilling services backlog and the percent of available operating days committed for the periods indicated:

(1)   Represents a nine-month period beginning April 1, 2008.
 
(2)   Our drilling contracts with Petroleo Brasileiro S.A. (“Petrobras”) provide an opportunity for us to earn performance bonuses based on absence of downtime experienced for our rigs operating offshore Brazil. With respect to our semisubmersibles operating offshore Brazil, we have included in our backlog amounts an amount equal to 75 percent of potential performance bonuses for such semisubmersibles, which amount is based on and consistent with our historical earnings of performance bonuses for these rigs. With respect to our drillships operating offshore Brazil, we (a) have not included in our backlog amounts any performance bonuses for periods prior to the commencement of certain upgrade projects planned for 2010 and 2011, which projects are designed to enhance the reliability and operational performance of our drillships, and (b) we have included in our backlog amounts an amount equal to 75 percent of potential performance bonuses for periods after the estimated completion of such upgrade projects. Our “total” backlog amount for semisubmersibles/drillships includes $350 million attributable to these performance bonuses.
 
(3)   Percentages take into account additional capacity from the estimated dates of deployment of our newbuild rigs that are scheduled to commence operations during 2008 and 2009.
     All of our contract drilling services backlog consists of commitments we believe to be firm. Our contract drilling services backlog reported above reflects estimated future revenues attributable to both signed drilling contracts and operator commitments under letters of intent. A letter of intent is generally subject to customary conditions, including the execution of a definitive drilling contract. 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 due to various factors, including, but not limited to, shipyard and maintenance projects, unplanned downtime, weather conditions and other factors that result in lower applicable dayrates 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. As a result, our backlog as of any particular date may not be indicative of our actual operating results for the succeeding periods for which the backlog is calculated.

     In June 2007, we announced that we were conducting an internal investigation of our Nigerian operations, focusing on the legality under the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”), and local laws of our Nigerian affiliate’s reimbursement of certain expenses incurred by our customs agents in connection with obtaining and renewing permits for the temporary importation of drilling units and related equipment into Nigerian waters, including permits that are necessary for our drilling units to operate in Nigerian waters. We also announced that the audit committee of Noble’s board of directors had engaged a leading law firm with significant experience in investigating and advising on FCPA matters to lead the investigation as independent outside counsel. The scope of the investigation also includes our dealings with customs agents and customs authorities in certain parts of the world other than Nigeria in which we conduct our operations, as well as dealings with other types of local agents in Nigeria and these other parts of the world. There can be no assurance that evidence of additional potential FCPA violations may not be uncovered through the investigation.
     The audit committee commissioned the internal investigation after our management brought to the attention of the audit committee a news release issued by another company that disclosed that the other company was conducting an internal investigation into the FCPA implications of certain actions by a customs agent in Nigeria in connection with the temporary importation of that company’s vessels into Nigeria. Our drilling units that conduct operations in Nigeria do so under temporary import permits, and management considered it prudent to review our own practices in this regard.
     We voluntarily contacted the SEC and the U.S. Department of Justice (“DOJ”) to advise them that an independent investigation was under way. We have been cooperating, and intend to continue to cooperate, fully with both agencies. If the SEC or the DOJ determines that violations of the FCPA have occurred, they could seek civil and criminal sanctions, including monetary penalties, against us and/or certain of our employees, as well as additional changes to our business practices and compliance programs, any of which could have a material adverse effect on our business or financial condition. In addition, such actions, whether actual or alleged, could damage our reputation and ability to do business, to attract and retain employees, and to access capital markets. Further, detecting, investigating, and resolving such actions is expensive and consumes significant time and attention of our senior management.
     The internal investigation is ongoing, and we cannot predict whether either the SEC or the DOJ will open its own proceeding to investigate this matter, or if a proceeding is opened, what potential remedies these agencies may seek. We could also face fines or sanctions in relevant foreign jurisdictions. Based on information obtained to date in our internal investigation, we have not determined that any potential liability that may result is either probable or can be reasonably estimated. As a result, we have not made any accrual in our financial statements at March 31, 2008.
     We are currently operating four jackup rigs offshore Nigeria, each of which has a temporary import permit through May 27, 2008. We recently filed with the Nigerian Customs Service applications for extensions of the temporary import permits for each of these rigs. Our management continues to seek to avoid material disruption to our Nigerian operations; however, there can be no assurance that we will be able to obtain further extensions necessary to continue operations of our rigs in Nigeria after expiration of the current term of the temporary import permits. If we cannot obtain a further extension necessary to continue operations of any rig, we may need to terminate the drilling contract of such rig and relocate such rig from Nigerian waters. 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.
     Notwithstanding that the internal investigation is ongoing, we have concluded that certain changes to our FCPA compliance program would provide us greater assurance that our assets are not used, directly or indirectly, to make improper payments, including customs payments, and that we are in compliance with the FCPA’s record-keeping requirements. Although we have had a long-standing published policy requiring compliance with the FCPA and broadly prohibiting any improper payments by us to foreign or domestic officials, we have since the commencement of the internal investigation adopted, and may adopt additional, intermediate measures intended to enhance FCPA compliance procedures. Additional measures may be required once the investigation concludes.

     Operating Revenues. Contract drilling services revenues increased $221 million in the Current Quarter, or 38 percent over the Comparable Quarter, primarily due to higher average dayrates. Higher average dayrates increased revenues approximately $199 million while more operating days in the Current Quarter increased revenues approximately $22 million. Average dayrates increased from $121,705 to $163,772, or $42,067 (35 percent), in the Current Quarter as compared to the Comparable Quarter. Higher average dayrates were received across all rig categories, except for our submersible rigs, which were impacted by weakening demand in the shallow waters of the U.S. Gulf of Mexico.
     Operating days increased from 4,740 in the Comparable Quarter to 4,872 in the Current Quarter or 132 days (three percent). Two newbuilds, the ultra-deepwater semisubmersible Noble Clyde Boudreaux and the enhanced premium jackup Noble Roger Lewis, which were added to the fleet in June and September 2007,

30


Table of Contents

respectively, contributed 182 additional operating days in the Current Quarter. The Current Quarter had one more available operating day than the Comparable Quarter due to leap year, which added 54 more operating days in the Current Quarter for our 54 operating rigs. These additional operating days were partially offset by 90 fewer operating days on our shallow water U.S. Gulf of Mexico submersible the Noble Fri Rodli, which was cold stacked in October 2007. Additionally, the Current Quarter had 13 more unpaid shipyard and regulatory inspection days than the Comparable Quarter.
     Operating Costs and Expenses. Contract drilling services operating costs and expenses increased $39 million, or 20 percent, in the Current Quarter over the Comparable Quarter. The Noble Clyde Boudreaux and the Noble Roger Lewis added $13 million of operating costs in the Current Quarter. Excluding the effect of our newbuild rigs, our labor costs increased $17 million in the Current Quarter over the Comparable Quarter due to higher compensation, including retention programs designed to retain key rig and operations personnel. Higher agency fees of $3 million were incurred in the Current Quarter in those countries where we retain agents who are compensated based on a percentage of revenues. The remaining $6 million of the operating cost increase in the Current Quarter over the Comparable Quarter was primarily due to increases in costs of daily rig operations, including catering, fuel, crew rotation, maintenance and safety and training costs.
     Depreciation and amortization increased $19 million, or 31 percent, to $81 million in the Current Quarter over the Comparable Quarter due to $8 million of depreciation on the Noble Clyde Boudreaux and the Noble Roger Lewis and $11 million of additional depreciation related to other capital expenditures on our fleet since the Comparable Quarter.

     Operating Revenues. Our labor contract drilling services revenues decreased $6 million in the Current Quarter over the Comparable Quarter primarily due to $8 million less revenue from the jackup Noble Kolskaya. The drilling contract for the Noble Kolskaya terminated and the jackup was warm stacked in February 2008. We are preparing to redeliver the Noble Kolskaya, operated under a bareboat charter, to its owner upon expiration of the term of its charter. This decrease in revenue was partially offset by a $2 million increase in our Canadian and North Sea labor contract revenues.
     Engineering, consulting and other operating revenues decreased $2 million in the Current Quarter over the Comparable Quarter due to closure of the operations of our Triton Engineering Services Inc. (“Triton”) subsidiary in March 2007 and the sale of the rotary steerable assets and intellectual property of our Noble Downhole Technology Ltd. (“Downhole Technology”) subsidiary in November 2007. We no longer conduct engineering and consulting operations.

Table of Contents

     Operating Costs and Expenses. Labor contract drilling services costs and expenses decreased $3 million in the Current Quarter over the Comparable Quarter primarily due to $6 million less bareboat charter and other operating costs on the Noble Kolskaya as a result of its drilling contract termination. Operating costs associated with our Canadian and North Sea labor contracts increased $3 million.
     Engineering, consulting and other expenses decreased $4 million due to the sale of the rotary steerable assets and intellectual property of Downhole Technology and the closure of the operations of Triton. The Comparable Quarter included $2 million of additional costs associated with the closure of the operations of Triton.
     Depreciation and amortization decreased $500,000 primarily due to lower depreciation expense on the Noble Kolskaya during the Current Quarter.
  Other Items
     Selling, General and Administrative Expenses. Consolidated selling, general and administrative expenses increased $7 million in the Current Quarter over the Comparable Quarter primarily due to $7 million of costs incurred in the internal investigation of our Nigerian operations.
     Interest Expense. Interest expense, net of amount capitalized decreased $400,000 primarily due to lower debt levels in the Current Quarter than the Comparable Quarter. Capitalized interest for the Current Quarter of $12 million was the same as the Comparable Quarter.
     Other, net. Other, net increased $2 million in the Current Quarter over the Comparable Quarter primarily due to $2 million of higher interest income as a result of higher cash and cash equivalent balances during the Current Quarter.
     Income Tax Provision. The income tax provision increased $24 million primarily due to higher pre-tax earnings in the Current Quarter over the Comparable Quarter. The higher pre-tax earnings increased income tax expense by $31 million, offset by a lower effective tax rate, 18.0 percent in the Current Quarter compared to 19.5 percent in the Comparable Quarter, which decreased income tax expense by $7 million. The lower effective tax rate in the Current Quarter resulted primarily from higher pre-tax earnings of non-U.S. owned assets, which generally have a lower statutory tax rate.
LIQUIDITY AND CAPITAL RESOURCES
  Overview
     Our principal capital resource in the Current Quarter was net cash provided by operating activities of $493 million, which compared to $270 million in the Comparable Quarter. The increase in net cash provided by operating activities in the Current Quarter was primarily attributable to higher net income. At March 31, 2008, we had cash and cash equivalents of $320 million and $418 million of funds available under our bank credit facility described under “Credit Facilities and Long-Term Debt” below. We had working capital of $507 million and $367 million at March 31, 2008 and December 31, 2007, respectively. Total debt as a percentage of total debt plus shareholders’ equity was 14 percent at March 31, 2008 and 15 percent at December 31, 2007.
     On February 2, 2007, Noble’s board of directors increased our share repurchase program authorization by 20 million shares, resulting in 30.5 million shares authorized for repurchase. During the three months ended March 31, 2008, we repurchased 0.6 million of our ordinary shares pursuant to this program at an average price of $44.81 per share for a total cost of $27 million. During 2007, we repurchased 4.2 million of our ordinary shares at an average price of $42.31 per share for a total cost of $179 million. At March 31, 2008, 25.7 million shares remained available for repurchase under such authorization. Additional repurchases, if any, may be made on the open market or in private transactions at prices determined by us.
     During the three months ended March 31, 2008, we made contributions to our pension plans totaling $3 million. We expect to contribute, subject to applicable law, an aggregate of $9 million to our pension plans in 2008, which includes the $3 million in contributions made during the three months ended March 31, 2008.

Table of Contents

     In April 2008, Noble’s board of directors declared a special cash dividend of $0.75 per ordinary share. The special dividend will be paid on May 16, 2008 to holders of record on April 30, 2008 and will total approximately $202 million. Our most recent quarterly cash dividend declaration, to be paid on May 30, 2008 to holders of record on May 14, 2008, was $0.04 per ordinary share, or approximately $43 million annualized. The declaration and payment of dividends in the future are at the discretion of Noble’s board of directors and the amount thereof will depend on our results of operations, financial condition, cash requirements, future business prospects, contractual restrictions and other factors deemed relevant by Noble’s board of directors.
  Capital Expenditures
     Capital expenditures totaled $234 million and $237 million for the Current Quarter and Comparable Quarter, respectively.
     We have five rigs under construction, resulting in capital expenditures for new construction in the Current Quarter totaling $134 million. Capital expenditures for new construction included $43 million for the Noble Danny Adkins, $37 million for the Noble Jim Day and $35 million for the Noble Dave Beard. Additionally, the Current Quarter included $19 million for the construction of the Noble Hans Deul and Noble Scott Marks, each a F&G JU-2000E enhanced premium newbuild jackup under construction. Other capital expenditures totaled $77 million in the Current Quarter and included approximately $40 million for major upgrade projects. Major maintenance expenditures totaled $23 million in the Current Quarter.
     Our capital expenditures and major maintenance expenditures for 2008 are budgeted at approximately $1.45 billion. In connection with our 2008 and future capital expenditure programs, we had entered into certain commitments, including shipyard and purchase commitments, of approximately $734 million outstanding at March 31, 2008.
     Certain projects currently under consideration could require, if they materialize, capital expenditures or other cash requirements not included in the 2008 budget. In addition, we will continue to evaluate acquisitions of drilling units from time to time. Factors that could cause actual capital expenditures to materially exceed the planned capital expenditures include delays and cost overruns in shipyards, shortages of equipment, latent damage or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions, and changes in design criteria or specifications during repair or construction.
     We believe that our cash and cash equivalents, net cash provided by operating activities, available capacity under the bank credit facility, and access to other financing sources will be adequate to meet our anticipated short-term and long-term liquidity requirements, including capital expenditures and scheduled debt repayments.
  Credit Facilities and Long-Term Debt
     Noble entered into an unsecured revolving bank credit facility in 2007 totaling $600 million (the “Bank Credit Agreement”), including a letter of credit facility totaling $150 million, which has an initial term of five years. In the first quarter of 2008, the term of the Bank Credit Agreement was extended for an additional one-year period, from March 15, 2012 to March 15, 2013. During this one-year extension, the total amount available under the Bank Credit Agreement will be $575 million, with Noble retaining the right to seek an increase of the total amount available to $600 million through existing lenders under the Bank Credit Agreement or new lenders. Noble Drilling Corporation has issued a guaranty of the obligations under the Bank Credit Agreement. At March 31, 2008, we had $50 million in borrowings and $132 million of letters of credit outstanding under this facility, leaving $418 million remaining available thereunder. In addition to letters of credit issued under the Bank Credit Agreement, we had letters of credit of $159 million and performance and customs bonds totaling $207 million supported by surety bonds outstanding at March 31, 2008. Of the total $291 million letters of credit outstanding at March 31, 2008, $236 million were issued to support bank bonds in connection with the temporary import extensions for our drilling units in Nigeria. 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 debt decreased from $785 million (including current maturities of $10 million) at December 31, 2007 to $732 million (including current maturities of $31 million) at March 31, 2008, due to debt repayments under the Bank Credit Agreement of $50 million coupled with other debt repayments of $3 million. At March 31, 2008 and December 31, 2007, we had no off-balance sheet debt or other off-balance sheet arrangements. At March 31, 2008, we were in compliance with all our debt covenants.

NEW ACCOUNTING PRONOUNCEMENTS
     In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (“SFAS No. 161”). SFAS No. 161 requires entities with derivative instruments to disclose information to enable financial statement users to understand how and why the entity uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS No. 133 and how derivative instruments and related hedged items affect the entity’s financial position, financial performance and cash flows. SFAS No. 161 is effective for fiscal years and interim periods beginning after November 15, 2008. We are currently evaluating the impact, if any, that SFAS No. 161 will have on our consolidated financial statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
     Market risk is the potential for loss due to 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 the Bank Credit Agreement. Interest on the Bank Credit Agreement is at an agreed upon percentage point spread over LIBOR. At March 31, 2008, there was $50 million outstanding under the Bank Credit Agreement. A change of one percent in the interest rate would cause a $500,000 change in interest expense on an annual basis on this amount of borrowings.
  Foreign Currency Risk
     Although we conduct business globally, a substantial majority of the value of our foreign transactions are denominated in U.S. Dollars. With certain exceptions, typically involving national oil companies, we structure our drilling contracts in U.S. Dollars to mitigate our exposure to fluctuations in foreign currencies. Other than trade accounts receivable and trade accounts payable, which mostly offset one another, we do not currently have material amounts of assets, liabilities, or financial instruments that are sensitive to foreign currency exchange rates.
     We periodically enter into derivative instruments to manage our cash flow exposure to fluctuations in interest rates and foreign currency exchange rates, and we may conduct hedging activities in future periods to mitigate such exposure. 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 operations have a significant amount of their cash operating expenses payable in either the Euro or British Pound, and we maintain forward currency contracts settling monthly in Euro and British Pounds. The Euro-denominated forward currency contracts settling in the remainder of 2008 represent approximately 40 percent of our forecasted Euro requirements. The British Pound-denominated forward contracts settling in the remainder of 2008 represent approximately 19 percent of our forecasted British Pound requirements. The notional amount of forward contracts outstanding at March 31, 2008 was approximately 8 million Euros and 5 million British Pounds. The aggregate notional amount of these forward contracts, expressed in U.S. Dollars, was $21 million at March 31, 2008. The fair market value of outstanding forward contracts was $2 million at March 31, 2008. A one percent change in exchange rates for the Euro and British Pound would change the fair value of these forward contracts by approximately $200,000.
  Market Risk
     We sponsor the Noble Drilling Corporation 401(k) Savings Restoration Plan (“Restoration Plan”). The Restoration Plan has no assets, and amounts “contributed” to the Restoration Plan are kept by us for general corporate purposes. The investments selected by employees and associated returns are tracked on a phantom basis. Accordingly, we have a liability to employees for amounts originally contributed 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 March 31, 2008, our liability under the Restoration Plan totaled $13 million. At March 31, 2008, a one percent increase or decrease in the fair value of the phantom investments would increase or decrease our liability by $130,000.
ITEM 4. CONTROLS AND PROCEDURES
     Noble’s Chairman of the Board, President and Chief Executive Officer, David W. Williams, and Noble’s Senior Vice President, Chief Financial Officer, Treasurer and Controller, Thomas L. Mitchell, have evaluated the Company’s disclosure controls and procedures as of the end of the period covered by this report. On the basis of this evaluation, Mr. Williams and Mr. Mitchell concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2008. The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company 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 were no changes in the Company’s internal control over financial reporting that occurred during the quarter ended March 31, 2008 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
     Information regarding legal proceedings is set forth in the first five paragraphs in Note 9 to our condensed 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
     There have been no material changes from the risk factors as previously disclosed in our Form 10-K for the year ended December 31, 2007 in response to Item 1A of Part I of Form 10-K, except to the extent the following items are updated or otherwise modified:
We may have difficulty obtaining or maintaining insurance in the future and we cannot fully insure against all of the risks and hazards we face.
     No assurance can be given that we will be able to obtain insurance against all risks or that we will be able to obtain or maintain adequate insurance in the future at rates and with deductibles or retention amounts that we consider commercially reasonable.
     The 2005 losses sustained in the oil and gas industry from Hurricanes Katrina and Rita had a material adverse impact on marine energy insurance markets. Subsequent to these losses, the insurance industry has generally offered reduced coverage for U.S. Gulf of Mexico named windstorm perils, and has priced premiums for renewal programs of insured parties that sustained losses from these 2005 hurricanes on a basis designed to recover hurricane-related underwriting losses in an accelerated manner, particularly for companies that have an exposure in the U.S. Gulf of Mexico. Our March 2008 insurance program renewal included an annual aggregate coverage limit of $200 million applicable to our drilling units operating in the U.S. Gulf of Mexico for physical damage and loss of hire on certain units resulting from named windstorm perils. Our units deployed in the U.S. Gulf of Mexico include six semisubmersibles and three submersibles (two contracted submersibles and one cold stacked submersible). This coverage limit may not fully insure our losses in the event that one or more named windstorms damage our drilling units in the U.S. Gulf of Mexico. The reduction in coverage does not apply to our units in the Mexican portion of the 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 further increases in insurance costs, additional coverage restrictions or unavailability of certain insurance products.
     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 war risk, activities prohibited by U.S. laws and regulations, radiation hazards, certain loss or damage to property on board our rigs and losses relating to terrorist acts or strikes. If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it could adversely affect our financial position, results of operations or cash flows. 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.

Our international operations involve additional risks not associated with U.S. Gulf of Mexico operations.
     We operate in various regions throughout the world that may expose us to political and other uncertainties, including risks of:
    terrorist acts, war and civil disturbances;
 
    seizure, nationalization or expropriation of property or equipment;
 
    foreign and U.S. monetary policy and foreign currency fluctuations and devaluations;
 
    the inability to repatriate income or capital;
 
    complications associated with repairing and replacing equipment in remote locations;
 
    piracy;
 
    import-export quotas, wage and price controls, imposition of trade barriers and other forms of government regulation and economic conditions that are beyond our control;
 
    regulatory or financial requirements to comply with foreign bureaucratic actions; and
 
    changing taxation policies.
     International contract drilling operations are subject to various laws and regulations in countries in which we operate, including laws and regulations relating to:
    the importing, exporting, equipping and operation of drilling units;
 
    repatriation of foreign earnings;
 
    currency exchange controls;
 
    oil and gas exploration and development;
 
    taxation of offshore earnings and earnings of expatriate personnel; and
 
    use and compensation of local employees and suppliers by foreign contractors.
     Our ability to do business in a number of jurisdictions is subject to maintaining required licenses and permits and complying with applicable laws and regulations. We are operating drilling units offshore Nigeria under temporary import permits that expire on May 27, 2008, and we may not be able to obtain new or extended temporary import permits for these units necessary to continue uninterrupted operations in Nigerian waters for the duration of the units’ drilling contracts. We cannot predict what changes, if any, relating to temporary import policies and procedures may be established or implemented in Nigeria in the future. For additional information regarding our ongoing internal investigation of our Nigerian operations and the status of our temporary import permits in Nigeria, see “Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Internal Investigation”. Changes in, compliance with, or our failure to comply with the laws and regulations of the countries where we operate, including Nigeria, may negatively impact our operations in those countries and could have a material adverse effect on our results of operations.
     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 letters 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

37


Table of Contents

Nigerian coastal shipping trade and are not in our view “vessels” within the meaning of Nigeria’s cabotage laws. On January 24, 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. NIMASA and the Minister of Transportation have filed a preliminary objection to our originating summons and the proceeding, which objection is scheduled for a hearing in May 2008. We intend to oppose the preliminary objection and 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.
     Governmental action, including initiatives by OPEC, may continue to cause oil price volatility. In some areas of the world, this governmental activity has adversely affected the amount of exploration and development work done by major oil companies, which may continue. In addition, some foreign governments favor or effectively require the awarding of drilling contracts to local contractors, require use of a local agent or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These practices may adversely affect our ability to compete and our results of operations.
