Note 2   Summary of Significant Accounting Policies
 
Interim Financial Information
 
The unaudited consolidated financial statements of Nabors are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Certain reclassifications have been made to the prior period to conform to the current period presentation, with no effect on our consolidated financial position, results of operations or cash flows. Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted. Therefore, these financial

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
statements should be read along with our annual report on Form 10-K for the year ended December 31, 2009 (“2009 Annual Report”). In management’s opinion, the consolidated financial statements contain all adjustments necessary to present fairly our financial position as of March 31, 2010 and the results of our operations, cash flows and changes in equity for the three months ended March 31, 2010 and 2009, in accordance with GAAP. Interim results for the three months ended March 31, 2010 may not be indicative of results that will be realized for the full year ending December 31, 2010.
 
Our independent registered public accounting firm has performed a review of, and issued a report on, these consolidated interim financial statements in accordance with standards established by the Public Company Accounting Oversight Board. Pursuant to Rule 436(c) under the Securities Act of 1933, as amended (the “Securities Act”), this report should not be considered a part of any registration statement prepared or certified within the meanings of Sections 7 and 11 of the Securities Act.
 
Principles of Consolidation
 
Our consolidated financial statements include the accounts of Nabors, as well as all majority owned and nonmajority owned subsidiaries required to be consolidated under GAAP. Our consolidated financial statements exclude majority owned entities for which we do not have either (1) the ability to control the operating and financial decisions and policies of that entity or (2) a controlling financial interest in a variable interest entity. All significant intercompany accounts and transactions are eliminated in consolidation.
 
Investments in operating entities where we have the ability to exert significant influence, but where we do not control operating and financial policies, are accounted for using the equity method. Our share of the net income (loss) of these entities is recorded as earnings (losses) from unconsolidated affiliates in our consolidated statements of income, and our investment in these entities is included as a single amount in our consolidated balance sheets. As of March 31, 2010 and December 31, 2009, investments in unconsolidated affiliates accounted for using the equity method totaled $305.1 million and $305.7 million, respectively, and investments in unconsolidated affiliates accounted for using the cost method totaled $1.9 million and $.9 million, respectively. Similarly, investments in certain offshore funds classified as long-term investments are accounted for using the equity method of accounting based on our ownership interest in each fund.
 
Recent Accounting Pronouncements
 
In December 2008, the SEC issued a final rule, “Modernization of Oil and Gas Reporting.” This rule revised some of the oil and gas reporting disclosures in Regulation S-K and Regulation S-X under the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as well as Industry Guide 2. Effective December 31, 2009, the Financial Accounting Standards Board (“FASB”) issued revised guidance that substantially aligned the oil and gas accounting disclosures with the SEC’s final rule. The amendments were designed to modernize and update oil and gas disclosure requirements to align them with current practices and changes in technology. Additionally, this new accounting standard requires that entities use 12-month average natural gas and oil prices when calculating the quantities of proved reserves and performing the full-cost ceiling test calculation. The new standard also clarified that an entity’s equity-method investments must be considered in determining whether it has significant oil and gas activities. The disclosure requirements were effective for registration statements filed on or after January 1, 2010 and for annual financial statements filed on or after December 31, 2009. The FASB provided a one-year deferral of the disclosure requirements if an entity became subject to the requirements because of a change to the definition of significant oil and gas activities. When operating results from our wholly owned oil and gas activities are considered with operating results from our unconsolidated oil and gas joint ventures, which we account for under the equity method of accounting, we have significant oil and gas activities under the new definition. In line with the one-year deferral, we will provide the oil and gas disclosures for annual financial statements for periods beginning after December 31, 2009 and registration statements filed on or after January 1, 2011.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
Effective January 1, 2010, we adopted the revised provisions relating to consolidation of variable interest entities within the Consolidations Topic of the Accounting Standards Codification (“ASC”). The revised provisions replaced the quantitative approach to identify a variable interest entity with a qualitative approach that focuses on an entity’s control and ability to direct the variable interest entity’s activities. The application of these provisions did not have a material impact on our consolidated financial statements.

(1) Our unrealized losses on available-for-sale debt securities held for more than one year relate to various types of securities. Each of these securities has a rating ranging from “A” to “AAA” from Standard & Poor’s and ranging from “A2” to “Aaa” from Moody’s Investors Service and is considered of high credit quality. In each case, we do not intend to sell these investments, and it is less likely than not that we will be required to sell them to satisfy our own cash flow and working capital requirements. We believe that we will be able to collect all amounts due according to the contractual terms of each investment and, therefore, did not consider the decline in value of these investments to be other-than-temporary at March 31, 2010.
 
The estimated fair values of our corporate, mortgage-backed, mortgage-CMO and asset-backed debt securities at March 31, 2010, classified by time to contractual maturity, are shown below. Expected maturities differ from contractual maturities because the issuers of the securities may have the right to repay obligations without prepayment penalties and we may elect to sell the securities prior to the contractual maturity date.

Note 4   Fair Value Measurements
 
Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market-corroborated, or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best information available. Accordingly, we employ valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The use of unobservable inputs is intended to allow for fair value determinations in situations where there is little, if any, market activity for the asset or liability at the measurement date. We are able to classify fair value balances utilizing a fair value hierarchy based on the observability of those inputs. Under the fair value hierarchy:
 
  •  Level 1 measurements include unadjusted quoted market prices for identical assets or liabilities in an active market;
 
  •  Level 2 measurements include quoted market prices for identical assets or liabilities in an active market that have been adjusted for items such as effects of restrictions for transferability and those that are not quoted, but are observable through corroboration with observable market data, including quoted market prices for similar assets; and
 
  •  Level 3 measurements include those that are unobservable and of a subjective measure.
 
The following table sets forth, by level within the fair value hierarchy, our financial assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2010. Our debt securities could transfer into or out of a Level 1 or 2 measure depending on the availability of independent and current pricing at the end of each quarter. During the three months ended March 31, 2010, there were no transfers of our financial assets and liabilities between Level 1 and 2 measures. Our financial assets and liabilities were classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Nonrecurring Fair Value Measurements
 
Fair value measurements are applied with respect to our nonfinancial assets and liabilities measured on a nonrecurring basis, which consist primarily of goodwill, oil and gas financing receivables, intangible assets and other long-lived assets, assets acquired and liabilities assumed in a business combination, and asset retirement obligations.
 
Fair Value of Financial Instruments
 
The fair value of our financial instruments has been estimated in accordance with GAAP. The fair value of our fixed rate long-term debt was estimated based on quoted market prices or prices quoted from third-party financial institutions. The carrying and fair values of our long-term debt, including the current portion, were as follows:
 
                 
    March 31, 2010  
(In thousands)   Carrying Value     Fair Value  
0.94% senior exchangeable notes due May 2011
  $ 1,491,292     $ 1,559,971

    $ 3,856,106     $ 4,290,252  
                 
 
 
(1) Included $1.0 million as of March 31, 2010 related to the unamortized loss on the interest rate swap that was unwound during the fourth quarter of 2005.
 
The fair values of our cash equivalents, trade receivables and trade payables approximated their carrying values due to the short-term nature of these instruments.
 
As of March 31, 2010, our short-term investments were carried at fair market value and included $138.9 million and $19.5 million in securities classified as available-for-sale and trading, respectively. The carrying values of our long-term investments accounted for using the equity method of accounting approximated fair value and totaled $7.8 million as of March 31, 2010. The carrying value of our oil and gas financing receivables included in long-term investments also approximated fair value and totaled $91.4 million as of March 31, 2010. Income and gains associated with our oil and gas financing receivables are recognized as operating revenues.
 
Note 5   Share-Based Compensation
 
We have several share-based employee compensation plans, which are more fully described in Note 4 — Share-Based Compensation to the audited financial statements included in our 2009 Annual Report.
 
Total share-based compensation expense, which includes both stock options and restricted stock, totaled $3.5 million and $23.3 million for the three months ended March 31, 2010 and 2009, respectively, and is included in direct costs and general and administrative expenses in our consolidated statements of income. Share-based compensation expense has been allocated to our various operating segments. See Note 13 — Segment Information.
 
During the three months ended March 31, 2010, we awarded 390,998 shares of restricted stock to our employees, directors and executive officers. These awards had an aggregate value at their grant date of $9.0 million and vest over periods of up to four years. There were no stock options granted, and, accordingly, no fair value determinations made during the three months ended March 31, 2010.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
During the three months ended March 31, 2009, we awarded options vesting over periods of up to four years to purchase 9,979,498 of our common shares to our employees, executive officers and directors. This included options to purchase 3.0 million and 1.7 million shares, with grant-date fair values of $8.8 million and $5.0 million, granted to our Chairman and Chief Executive Officer, Eugene M. Isenberg, and our Deputy Chairman, President and Chief Operating Officer, Anthony G. Petrello, respectively, in February 2009.
 
The fair value of stock options granted during the three months ended March 31, 2009 was calculated using the Black-Scholes option pricing model and the following weighted-average assumptions:
 
     
Weighted average fair value of options granted
  $2.84
Weighted average risk free interest rate
  1.75%
Dividend yield
  0%
Volatility(1)
  34.78%
Expected life
  4.0 years
 
 
(1) Expected volatilities were based on implied volatilities from publicly traded options to purchase Nabors’ common shares, historical volatility of Nabors’ common shares and other factors.
 
The total intrinsic value of options exercised during the three months ended March 31, 2010 and 2009 was $1.3 million and $.4 million, respectively. The total fair value of options that vested during the three months ended March 31, 2010 and 2009 was $5.4 million and $9.4 million, respectively.
 
Note 6   Investments in Unconsolidated Affiliates
 
We have several unconsolidated affiliates that are integral to our operations. For a full description, refer to Note 9 — Investments in Unconsolidated Affiliates to the audited financial statements in our 2009 Annual Report.
 
As of March 31, 2010 and December 31, 2009, our investments in unconsolidated affiliates accounted for using the equity method totaled $305.1 million and $305.7 million, respectively, and our investments in unconsolidated affiliates accounted for using the cost method totaled $1.9 million and $.9 million, respectively. During 2008, our unconsolidated U.S. oil and gas joint venture was deemed a significant subsidiary. Accordingly, summarized income statement information for this joint venture follows:

Note 7   Debt
 
As of March 31, 2010, our long-term debt included $1.5 billion of Nabors Delaware’s 0.94% senior exchangeable notes that will mature in May 2011, all of which will be reclassified to current debt in the second quarter of 2010. These notes are exchangeable into cash and, if applicable, Nabors common shares based on an exchange rate equal to 21.8221 common shares per $1,000 principal amount of notes (equal to an

initial exchange price of approximately $45.83 per share), subject to adjustment during the 30 calendar days ending at the close of business on the business day immediately preceding the maturity date. Upon exchange, we would only be required to issue incremental shares above the principal amount of the notes, since we are required to pay cash up to the principal amount of the notes exchanged.
 
Since 2008 and through March 31, 2010, we purchased $1.2 billion par value of these notes in the open market. In connection with the issuance of these notes in 2006, Nabors Delaware entered into exchangeable note hedge transactions with respect to our common shares. Call options were purchased to offset potential dilution upon exchange and warrants were sold to effectively increase the exchange price. In the first quarter of 2010, we entered into an agreement to unwind and settle some of the exchangeable note hedge and warrant transactions and received $.4 million from one of the counterparties to the transactions. These transactions were recorded as capital in excess of par value in our consolidated statement of changes in equity as of March 31, 2010.
 
The balances of the liability and equity components of the 0.94% senior exchangeable notes as of March 31, 2010 and December 31, 2009 were as follows:

Note 8   Income Taxes
 
We are subject to income taxes in the United States and numerous other jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. A number of our non-U.S. income tax returns from 1995 through 2007 are currently under audit examination. We anticipate that several of these audits could be finalized within the next 12 months. It is possible that the benefit that relates to our unrecognized tax positions could significantly increase or decrease within the next 12 months. However, based on the current status of examinations, and the protocol for finalizing audits with the relevant tax authorities, which could include formal legal proceedings, it is not possible to estimate the future impact of the amount of changes, if any, to record uncertain tax positions at March 31, 2010.

Note 9   Common Shares
 
During the three months ended March 31, 2010 and 2009, our employees exercised vested options to acquire .2 million and .1 million of our common shares, respectively, resulting in proceeds of $2.8 million and $.5 million, respectively.
 
During each of the three months ended March 31, 2010 and 2009, we withheld .1 million of our common shares with a fair value of $1.9 million and $.9 million, respectively, to satisfy certain tax withholding obligations due in connection with the grants of stock awards under our 2003 Employee Stock Plan.
 
During the three months ended March 31, 2010, our outstanding shares increased by 103,925 pursuant to stock option share settlements and exercises by Messrs. Isenberg and Petrello. As part of the transactions, unexercised vested stock options were surrendered to Nabors with a value of approximately $5.9 million to satisfy some of the option exercise price and related income taxes.
 
Note 10   Commitments and Contingencies
 
Commitments
 
Employment Contracts
 
Messrs. Isenberg and Petrello had employment agreements (“prior employment agreements”) in effect through the first quarter of 2009. Effective April 1, 2009, we entered into amended and restated employment agreements (“new employment agreements”) with them.
 
For the three months ended March 31, 2009, the prior employment agreements provided for annual cash bonuses of 6% and 2%, for Messrs. Isenberg and Petrello, respectively, of Nabors’ net cash flow (as defined in the respective employment agreements) in excess of 15% of the average shareholders’ equity for each fiscal year. Mr. Petrello’s bonus was subject to a minimum of $700,000 per year.
 
Effective April 1, 2009, the new employment agreements for Messrs. Isenberg and Petrello amended and restated the prior employment agreements. The new employment agreements provide for an extension of the employment term through March 30, 2013, with automatic one-year extensions beginning April 1, 2011, unless either party gives notice of nonrenewal. The base salaries for Messrs. Isenberg and Petrello were increased to $1.3 million and $1.1 million, respectively. Mr. Isenberg has agreed to donate the after-tax proceeds of his base salary to an educational fund intended to benefit Nabors’ employees or other worthy candidates.
 
On June 29, 2009, the new employment agreements for Messrs. Isenberg and Petrello were amended to provide for a reduction in the annual rate of base salary to $1.17 million per year and $990,000 per year, respectively, for the period from June 29, 2009 to December 27, 2009. On December 28, 2009, the agreements were further amended to extend through June 27, 2010 the previously agreed salary reduction.
 
In addition to a base salary, the new employment agreements provide for annual cash bonuses of 2.25% and 1.5%, for Messrs. Isenberg and Petrello, respectively, of Nabors’ net cash flow (as defined in the respective employment agreements) in excess of 15% of the average shareholders’ equity for each fiscal year. The new employment agreements also provide a quarterly deferred bonus of $.6 million and $.25 million, respectively, to the accounts of Messrs. Isenberg and Petrello under Nabors’ executive deferred compensation plan for each quarter they are employed beginning June 30, 2009 and, in Mr. Petrello’s case, ending March 30, 2019.
 
For 2009, the annual cash bonuses for Messrs. Isenberg and Petrello pursuant to the formulas described above were $15.4 million and $4.9 million, respectively, for the first quarter of 2009 in accordance with the prior employment agreements and $4.5 million and $3.0 million, respectively, for the second through fourth quarter of 2009 in accordance with their new employment agreements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
Messrs. Isenberg and Petrello also are eligible for awards under Nabors’ equity plans, may participate in annual long-term incentive programs and pension and welfare plans on the same basis as other executives, and may receive special bonuses from time to time as determined by the Board of Directors. The new employment agreements effectively eliminated the risk of forfeiture of outstanding stock awards. Accordingly, we recognized compensation expense during the second quarter of 2009 with respect to all of their previously granted unvested awards. As a result, as of December 31, 2009, there was no unrecognized compensation expense related to restricted stock and stock option awards for either of the executives.
 
Termination in the event of death, disability, or termination without cause (including in the event of a Change in Control).  The new employment agreements provide for severance payments in the event that either Mr. Isenberg’s or Mr. Petrello’s employment agreement is terminated (i) upon death or disability, (ii) by Nabors prior to the expiration date of the employment agreement for any reason other than for Cause, or (iii) by either individual for Constructive Termination Without Cause, each as defined in the respective employment agreements. Termination in the event of a Change in Control (as defined in the respective employment agreement) is considered a Constructive Termination Without Cause. Mr. Isenberg or his estate would be entitled to receive within 30 days of any such triggering event a payment of $100 million. Mr. Petrello or his estate would be entitled to receive within 30 days of his death or disability a payment of $50 million or, in the event of Termination Without Cause or Constructive Termination Without Cause, a payment based on a formula of three times the average of his base salary and annual bonus (calculated as though the bonus formula under the new employment agreement had been in effect) paid during the three fiscal years preceding the termination. If, by way of example, Mr. Petrello were Terminated Without Cause subsequent to March 31, 2010, his payment would be approximately $45 million. The formula will be further reduced to two times the average stated above effective April 1, 2015.
 
We do not have insurance to cover our obligations in the event of death, disability, or Termination Without Cause for either Messrs. Isenberg or Petrello, and we have not recorded an expense or accrued a liability relating to these potential obligations.
 
In addition, under the new employment agreements, the affected individual would be entitled to receive (a) any unvested restricted stock or stock options outstanding, which would immediately and fully vest; (b) any amounts earned, accrued or owing to the executive but not yet paid (including executive benefits, life insurance, disability benefits and reimbursement of expenses and perquisites), which would be continued through the later of the expiration date or three years after the termination date; (c) continued participation in medical, dental and life insurance coverage until the executive received equivalent benefits or coverage through a subsequent employer or until the death of the executive or his spouse, whichever were later; and (d) any other or additional benefits in accordance with applicable plans and programs of Nabors. The vesting of unvested equity awards would not result in the recognition of any additional compensation expense, as all compensation expense related to Messrs. Isenberg’s and Petrello’s outstanding awards has been recognized. In addition, the new employment agreements eliminate all tax gross-ups, including tax gross-ups on golden parachute excise taxes, which applied under the prior employment agreements. Estimates of the cash value of Nabors’ obligations to Messrs. Isenberg and Petrello under (b), (c) and (d) above are included in the payment amounts above.
 
Other Obligations.  In addition to salary and bonus, each of Messrs. Isenberg and Petrello receive group life insurance at an amount at least equal to three times their respective base salaries, various split-dollar life insurance policies, reimbursement of expenses, various perquisites and a personal umbrella insurance policy in the amount of $5 million. Premiums payable under the split-dollar life insurance policies were suspended as a result of the adoption of the Sarbanes-Oxley Act of 2002.

Contingencies
 
Income Tax Contingencies
 
We are subject to income taxes in the United States and numerous other jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We are regularly under audit by tax authorities. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different than what is reflected in our income tax provisions and accruals. The results of an audit or litigation could materially affect our financial position, income tax provision, net income, or cash flows in the period or periods challenged.
 
It is possible that future changes to tax laws (including tax treaties) could impact our ability to realize the tax savings recorded to date as well as future tax savings, resulting from our 2002 corporate reorganization. See Note 12 — Income Taxes to the audited financial statements in our 2009 Annual Report for additional discussion.
 
On September 14, 2006, Nabors Drilling International Limited, one of our wholly owned Bermuda subsidiaries (“NDIL”), received a Notice of Assessment (the “Notice”) from Mexico’s federal tax authorities in connection with the audit of NDIL’s Mexican branch for 2003. The Notice proposes to deny depreciation expense deductions relating to drilling rigs operating in Mexico in 2003. The Notice also proposes to deny a deduction for payments made to an affiliated company for the procurement of labor services in Mexico. The amount assessed was approximately $19.8 million (including interest and penalties). Nabors and its tax advisors previously concluded that the deductions were appropriate and more recently that the position of the tax authorities lacks merit. NDIL’s Mexican branch took similar deductions for depreciation and labor expenses from 2004 to 2008. On June 30, 2009, the tax authorities proposed similar assessments against the Mexican branch of another wholly owned Bermuda subsidiary, Nabors Drilling International II Ltd. (“NDIL II”) for 2006. We anticipate that a similar assessment will eventually be proposed against NDIL for 2004 through 2008 and against NDIL II for 2007 to 2010. We believe that the potential assessments will range from $6 million to $26 million per year for the period from 2004 to 2010, and in the aggregate, would be approximately $90 million to $95 million. Although we believe that any assessments relating to the 2004 to 2010 years would also lack merit, a reserve has been recorded in accordance with GAAP. If these additional assessments were made and we ultimately did not prevail, we would be required to recognize additional tax for the amount of the aggregate over the current reserve.
 
Self-Insurance
 
We self-insure for certain losses relating to workers’ compensation, employers’ liability, general liability, automobile liability and property damage. Effective April 1, 2010 with our insurance renewal, our deductible for offshore rigs was reduced from $10.0 million to $5.0 million. Our self-insured retentions for all other types of claims for 2010 remain the same as 2009 and are more fully described in Note 16 — Commitments and Contingencies to the audited financial statements in our 2009 Annual Report.
 
Litigation
 
Nabors and its subsidiaries are defendants or otherwise involved in a number of lawsuits in the ordinary course of business. We estimate the range of our liability related to pending litigation when we believe the amount and range of loss can be estimated. We record our best estimate of a loss when the loss is considered probable. When a liability is probable and there is a range of estimated loss with no best estimate in the range, we record the minimum estimated liability related to the lawsuits or claims. As additional information becomes available, we assess the potential liability related to our pending litigation and claims and revise our estimates. Due to uncertainties related to the resolution of lawsuits and claims, the ultimate outcome may

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
differ from our estimates. In the opinion of management and based on liability accruals provided, our ultimate exposure with respect to these pending lawsuits and claims is not expected to have a material adverse effect on our consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period.
 
On July 5, 2007, we received an inquiry from the U.S. Department of Justice relating to its investigation of one of our vendors and compliance with the Foreign Corrupt Practices Act. The inquiry relates to transactions with and involving Panalpina, which provides freight forwarding and customs clearance services to some of our affiliates. To date, the inquiry has focused on transactions in Kazakhstan, Saudi Arabia, Algeria and Nigeria. The Audit Committee of our Board of Directors engaged outside counsel to review some of our transactions with this vendor, has received periodic updates at its regularly scheduled meetings, and the Chairman of the Audit Committee has received updates between meetings as circumstances warrant. The investigation includes a review of certain amounts paid to and by Panalpina in connection with obtaining permits for the temporary importation of equipment and clearance of goods and materials through customs. Both the SEC and the Department of Justice have been advised of our investigation. The ultimate outcome of this investigation or the effect of implementing any further measures that may be necessary to ensure full compliance with applicable laws cannot be determined at this time.
 
A court in Algeria entered a judgment of approximately $19.7 million against us related to alleged customs infractions in 2009. We believe we did not receive proper notice of the judicial proceedings and that the amount of the judgment is excessive. We have asserted the lack of legally required notice as a basis for challenging the judgment on appeal to the Algeria Supreme Court. Based upon our understanding of applicable law and precedent, we believe that this challenge will be successful. We do not believe that a loss is probable and have not accrued any amounts related to this matter. However, the ultimate resolution and the timing thereof are uncertain. If we are ultimately required to pay a fine or judgment related to this matter, the amount of the loss could range from approximately $140,000 to $19.7 million.
 
Off-Balance Sheet Arrangements (Including Guarantees)
 
We are a party to some transactions, agreements or other contractual arrangements defined as “off-balance sheet arrangements” that could have a material future effect on our financial position, results of operations, liquidity and capital resources. The most significant of these off-balance sheet arrangements involve agreements and obligations under which we provide financial or performance assurance to third parties. Certain of these agreements serve as guarantees, including standby letters of credit issued on behalf of insurance carriers in conjunction with our workers’ compensation insurance program and other financial surety instruments such as bonds. We have also guaranteed payment of contingent consideration in conjunction with an acquisition in 2005. Potential contingent consideration is based on future operating results of the acquired business. In addition, we have provided indemnifications, which serve as guarantees, to some third parties. These guarantees include indemnification provided by Nabors to our share transfer agent and our insurance carriers. We are not able to estimate the potential future maximum payments that might be due under our indemnification guarantees.
 
Management believes the likelihood that we would be required to perform or otherwise incur any material losses associated with any of these guarantees is remote. The following table summarizes the total maximum

Note 11   Earnings Per Share
 
A reconciliation of the numerators and denominators of the basic and diluted earnings per share computations follows:

(1) Diluted earnings per share for the three months ended March 31, 2010 and 2009 excluded any incremental shares issuable upon exchange of the 0.94% senior exchangeable notes due 2011. Since 2008 and through March 31, 2010, we purchased $1.2 billion par value of these notes in the open market, leaving approximately $1.6 billion par value outstanding. The number of shares that we would be required to issue upon exchange consists of only the incremental shares that would be issued above the principal amount of the notes, as we would be required to pay cash up to the principal amount of the notes exchanged. We would issue an incremental number of shares only upon exchange of these notes. Such shares are included in the calculation of the weighted-average number of shares outstanding in our diluted earnings per share calculation only when our stock price exceeds $45.83 as of the last trading day of the quarter and the average price of our shares for the ten consecutive trading days beginning on the third business day after the last trading day of the quarter exceeds $45.83, which did not occur during any period for the three months ended March 31, 2010 and 2009.

(2) On July 31, 2009, the exchangeable shares of Nabors Exchangeco were exchanged for Nabors common shares on a one-for-one basis. Basic shares outstanding included (1) the weighted-average number of common shares and restricted stock of Nabors and (2) the weighted-average number of exchangeable shares of Nabors Exchangeco: 284.7 million shares cumulatively for the three months ended March 31, 2010 and 283.0 million and .1 million shares, respectively, for the three months ended March 31, 2009.
 
For all periods presented, the computation of diluted earnings per share excluded outstanding stock options and warrants with exercise prices greater than the average market price of Nabors’ common shares, because their inclusion would have been anti-dilutive and because they were not considered participating securities. The average number of options and warrants that were excluded from diluted earnings per share that would have potentially diluted earnings per share in the future were 10,055,869 and 31,023,161 shares during the three months ended March 31, 2010 and 2009, respectively. In any period during which the average market price of Nabors’ common shares exceeds the exercise prices of these stock options and warrants, such stock options and warrants are included in our diluted earnings per share computation using the if-converted method of accounting. Restricted stock is included in our basic and diluted earnings per share computation using the two-class method of accounting in all periods because it is considered a participating security.
 
Note 12   Supplemental Balance Sheet and Income Statement Information

(3) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $.6 million and $(72.2) million for the three months ended March 31, 2010 and 2009, respectively.
 
(4) Includes our drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software, and construction and logistics operations.

(7) Adjusted income derived from operating activities is computed by subtracting direct costs, general and administrative expenses, depreciation and amortization, and depletion expense from “Operating revenues” and then adding “Earnings (losses) from unconsolidated affiliates.” Such amounts should not be used as a substitute for those amounts reported under GAAP. However, management evaluates the performance of our business units and the consolidated company based on several criteria, including adjusted income derived from operating activities, because it believes that these financial measures are an accurate reflection of our ongoing profitability. A reconciliation of this non-GAAP measure to income before income taxes, which is a GAAP measure, is provided within the above table.
 
(8) Represents the elimination of inter-segment transactions and unallocated corporate expenses, assets and capital expenditures.

(11) Includes $68.8 million and $65.8 million of investments in unconsolidated affiliates accounted for using the equity method as of March 31, 2010 and December 31, 2009, respectively.
 
(12) Includes $1.9 million and $.9 million of investments in unconsolidated affiliates accounted for using the cost method as of March 31, 2010 and December 31, 2009, respectively.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
To the Board of Directors and Shareholders
of Nabors Industries Ltd.:
 
We have reviewed the accompanying consolidated balance sheet of Nabors Industries Ltd. and its subsidiaries (the “Company”) as of March 31, 2010, and the related consolidated statements of income and changes in equity for the three-month periods ended March 31, 2010 and 2009, and the consolidated statement of cash flows for the three-month periods ended March 31, 2010 and 2009. This interim financial information is the responsibility of the Company’s management.
 
We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
 
Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.
 
We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2009, and the related consolidated statements of income, changes in equity and of cash flows for the year then ended (not presented herein), and in our report dated February 26, 2010, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of March 31, 2010, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

Item 2.   Management’s Discussion and Analysis of Financial Condition and Results of Operations
 
FORWARD-LOOKING STATEMENTS
 
We often discuss expectations regarding our future markets, demand for our products and services, and our performance in our annual and quarterly reports, press releases, and other written and oral statements. Statements that relate to matters that are not historical facts are “forward-looking statements” within the meaning of the safe harbor provisions of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. These forward-looking statements are based on an analysis of currently available competitive, financial and economic data and our operating plans. They are inherently uncertain and investors should recognize that events and actual results could turn out to be significantly different from our expectations. By way of illustration, when used in this document, words such as “anticipate,” “believe,” “expect,” “plan,” “intend,” “estimate,” “project,” “will,” “should,” “could,” “may,” “predict” and similar expressions are intended to identify forward-looking statements.
 
You should consider the following key factors when evaluating these forward-looking statements:
 
  •  fluctuations in worldwide prices of and demand for natural gas and oil;
 
  •  fluctuations in levels of natural gas and oil exploration and development activities;
 
  •  fluctuations in the demand for our services;
 
  •  the existence of competitors, technological changes and developments in the oilfield services industry;
 
  •  the existence of operating risks inherent in the oilfield services industry;
 
  •  the existence of regulatory and legislative uncertainties;
 
  •  the possibility of changes in tax laws;
 
  •  the possibility of political instability, war or acts of terrorism in any of the countries in which we do business; and
 
  •  general economic conditions including the capital and credit markets.
 
Our businesses depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Therefore, a sustained increase or decrease in the price of natural gas or oil, which could have a material impact on exploration, development and production activities, could also materially affect our financial position, results of operations and cash flows.
 
The above description of risks and uncertainties is by no means all-inclusive, but is designed to highlight what we believe are important factors to consider. For a more detailed description of risk factors, please refer to our 2009 Annual Report under Part I, Item 1A. — Risk Factors.
 
Management Overview
 
The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to help the reader understand the results of our operations and our financial condition. This information is provided as a supplement to, and should be read in conjunction with, our consolidated financial statements and the accompanying notes thereto.
 
The majority of our business is conducted through our various Contract Drilling operating segments, which include our drilling, workover and well-servicing operations, on land and offshore. Our oil and gas exploration, development and production operations are included in our Oil and Gas operating segment. Our operating segments engaged in drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software, and construction and logistics operations are aggregated in our Other Operating Segments.
 
Our businesses depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Therefore, a sustained increase or decrease in the price of

natural gas or oil, which could have a material impact on exploration, development and production activities, could also materially affect our financial position, results of operations and cash flows.
 
Natural gas prices are the primary drivers of our U.S. Lower 48 Land Drilling and Canadian Contract Drilling operations, while oil prices are the primary driver in our Alaskan, International, U.S. Offshore (Gulf of Mexico), Canadian well-servicing and U.S. Land Well-servicing operations. The Henry Hub natural gas spot price (per Bloomberg) averaged $4.07 per million cubic feet (mcf) during the 12-month period from April 1, 2009 through March 31, 2010, down from a $7.91 per mcf average during the prior 12-months. West Texas intermediate spot oil prices (per Bloomberg) averaged $70.62 per barrel from April 1, 2009 through March 31, 2010, down from a $86.68 per barrel average during the preceding 12-months.
 
Operating revenues and Earnings (losses) from unconsolidated affiliates for the three months ended March 31, 2010 totaled $905.7 million, representing a decrease of $227.9 million, or 20% as compared to the three months ended March 31, 2009. Adjusted income derived from operating activities and net income attributable to Nabors for the three months ended March 31, 2010 totaled $138.5 million and $40.2 million ($.14 per diluted share), respectively, representing decreases of 30% and 68%, respectively, compared to the three months ended March 31, 2009.
 
During the three months ended March 31, 2009, our operating results were negatively impacted as a result of a charge arising from an oil and gas full-cost ceiling test writedown. Earnings (losses) from unconsolidated affiliates included $(75.0) million, which represented our proportionate share of the full-cost ceiling test writedown from our unconsolidated domestic oil and gas joint venture. The full-cost ceiling test writedown is included in our Oil and Gas operating segment results.
 
Excluding the full-cost ceiling test writedown discussed above, our operating results during the three months ended March 31, 2010 were lower than the corresponding 2009 quarter results primarily due to the continuing weak environment in our U.S. Lower 48 Land Drilling, U.S. Land Well-servicing, Alaska, U.S. Offshore and International operations where activity levels and demand for our drilling rigs have decreased substantially in response to sustained commodity price deterioration. Operating results have been further negatively impacted by higher levels of depreciation expense due to our increased capital expenditures in recent years.
 
Our operating results for 2010 are expected to approximate levels realized during 2009 given our current expectation of the continuation of lower commodity prices during 2010 and the related impact on drilling and well-servicing activity and dayrates. We expect the decrease in drilling activity and dayrates to continue to adversely impact our U.S. Lower 48 Land Drilling and U.S. Land Well-servicing operations for 2010, as compared to 2009, because the number of working rigs and average dayrates have declined. We expect our International operations to decrease during 2010 as a result of lower drilling activity and utilization partially offset by the deployment of new and incremental rigs under long-term contracts and the renewal of multi-year contracts. Although rig count is expected to be lower overall, the reductions are primarily comprised of lower yielding assets, leaving higher margin contracts in place partially offset by some contracts rolling over at lower current market rates. Our investments in new and upgraded rigs over the past five years have resulted in long-term contracts which we expect will enhance our competitive position when market conditions improve.

(2) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $.1 million and $1.3 million for the three months ended March 31, 2010 and 2009, respectively.
 
(3) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $.6 million and $(72.2) million for the three months ended March 31, 2010 and 2009, respectively.
 
(4) Includes our drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software, and construction and logistics operations.
 
(5) Includes earnings (losses), net from unconsolidated affiliates, accounted for using the equity method, of $3.0 million and $6.5 million for the three months ended March 31, 2010 and 2009, respectively.
 
(6) Represents the elimination of inter-segment transactions.
 
(7) Adjusted income derived from operating activities is computed by subtracting direct costs, general and administrative expenses, depreciation and amortization, and depletion expense from “Operating revenues” and then adding “Earnings (losses) from unconsolidated affiliates.” Such amounts should not be used as a substitute for those amounts reported under GAAP. However, management evaluates the performance of our business units and the consolidated company based on several criteria, including adjusted income derived from operating activities, because it believes that these financial measures are an accurate reflection of our ongoing profitability. A reconciliation of this non-GAAP measure to income before income taxes, which is a GAAP measure, is provided within the above table.
 
(8) Represents the elimination of inter-segment transactions and unallocated corporate expenses.
 
(9) Excludes well-servicing rigs, which are measured in rig hours. Includes our equivalent percentage ownership of rigs owned by unconsolidated affiliates. Rig years represent a measure of the number of equivalent rigs operating during a given period. For example, one rig operating 182.5 days during a 365-day period represents 0.5 rig years.
 
(10) International rig years include our equivalent percentage ownership of rigs owned by unconsolidated affiliates which totaled 2.5 years and 2.8 years during the three months ended March 31, 2010 and 2009, respectively.
 
(11) Rig hours represents the number of hours that our well-servicing rig fleet operated during the year.
 
Segment Results of Operations
 
Contract Drilling
 
Our Contract Drilling operating segments contain one or more of the following operations: drilling, workover and well-servicing, on land and offshore.
 
U.S. Lower 48 Land Drilling.  The results of operations for this reportable segment were as follows:
 
                                 
    Three Months Ended March 31,     Increase
 
    2010     2009     (Decrease)  
(In thousands, except percentages and rig activity)  
 
Operating revenues and Earnings from unconsolidated affiliates
  $ 271,497     $ 389,879     $ (118,382 )     (30 %)
Adjusted income derived from operating activities
  $ 60,286     $ 129,242     $ (68,956 )     (53 %)
Rig years
    158.6       192.8       (34.2 )     (18 %)
 
Operating results decreased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily due to a decline in average dayrates and drilling activity, driven by lower natural gas prices. Additionally, decreases reflect the decline in early contract termination revenue to $10.9 million recognized during the three months ended March 31, 2010 as compared to $31.3 million recognized during the same 2009 quarter. We expect to recognize revenues relating to early contract termination of contracts at a significantly diminished rate during 2010 relative to 2009.

Rig hours
    148,347       179,567       (31,220 )     (17 %)
 
Operating results decreased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily due to lower rig utilization and price erosion, attributed to lower customer demand for our services due to lower oil prices caused by the U.S. economic recession. These decreases were partially offset by lower depreciation expense.
 
U.S. Offshore.  The results of operations for this reportable segment were as follows:
 
                                 
    Three Months Ended March 31,     Increase
 
    2010     2009     (Decrease)  
(In thousands, except percentages and rig activity)

Rig years
    12.0       15.3       (3.3 )     (22 %)
 
The decrease in operating results during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily resulted from lower average dayrates and utilization for the SuperSundownertm platform, workover jack-up, barge drilling, and Sundowner® platform rigs, partially offset by higher utilization of our barge workover rig.
 
Alaska.  The results of operations for this reportable segment were as follows:
 
                                 
    Three Months Ended March 31,     Increase
 
    2010     2009     (Decrease)  
(In thousands, except percentages and rig activity)

  $ 49,794     $ 62,782     $ (12,988 )     (21 %)
Adjusted income derived from operating activities
  $ 13,957     $ 20,825     $ (6,868 )     (33 %)
Rig years
    9.1       11.9       (2.8 )     (24 %)
 
The decrease in operating results during the three months ended March 31, 2010 compared to the corresponding 2009 quarter were primarily due to decreases in average dayrates and drilling activity, driven by lower oil prices.
 
Canada.  The results of operations for this reportable segment were as follows:
 
                                 
    Three Months Ended March 31,     Increase
 
    2010     2009     (Decrease)  
(In thousands, except percentages and rig activity)  
 
Operating revenues and Earnings from unconsolidated affiliates
  $ 115,560     $ 113,594     $ 1,966       2 %
Adjusted income derived from operating activities
  $ 14,565     $ 13,335     $ 1,230       9 %
Rig years
    34.8       34.4       0.4       1 %
Rig hours
    46,032       50,224       (4,192 )     (8 %)
 
Operating results increased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily as a result of an overall increase in drilling and well-servicing dayrates, which has offset the declines in activity driven by continued lower customer demand and lower commodity prices. Our operating results for the three months ended March 31, 2010 were positively impacted by cost reduction efforts, including lower general and administrative expenses. Additionally, revenues were positively impacted

by the strengthening of the Canadian dollar versus the U.S. dollar because much of our customer revenue is denominated in Canadian dollars.
 
International.  The results of operations for this reportable segment were as follows:
 
                                 
    Three Months Ended March 31,     Increase
 
    2010     2009     (Decrease)  
(In thousands, except percentages and rig activity)  
 
Operating revenues and Earnings from unconsolidated affiliates

Adjusted income derived from operating activities
  $ 53,579     $ 102,975     $ (49,396 )     (48 %)
Rig years
    88.3       114.0       (25.7 )     (23 %)
 
The decrease in operating results during the three months ended March 31, 2010 compared to the corresponding 2009 quarter resulted primarily from decreases in average dayrates and lower utilization of rigs in Mexico, Saudi Arabia, Oman, Kazakhstan and Algeria driven by weakening customer demand for drilling services stemming from lower oil prices.
 
Oil and Gas.  The results of operations for this reportable segment were as follows:
 
                                 
    Three Months Ended March 31,     Increase
 
    2010     2009     (Decrease)  
(In thousands, except percentages)  
 
Operating revenues and Earnings (losses) from unconsolidated affiliates
  $ 17,324     $ (60,044 )   $ 77,368       129 %
Adjusted income (loss) derived from operating activities
  $ (727 )   $ (71,334 )   $ 70,607       99 %
 
Operating results increased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily as a result of our unconsolidated domestic oil and gas joint venture’s full-cost ceiling test writedown recorded during the first quarter of 2009, of which our proportionate share totaled $75.0 million. This writedown resulted from the application of the full-cost method of accounting for costs related to oil and natural gas properties. These increases in operating results were partially offset by higher depletion costs of $4.0 million and reduced income related to our oil and gas financing receivables.
 
Other Operating Segments
 
These operations include our drilling technology and top-drive manufacturing, directional drilling, rig instrumentation and software, and construction and logistics operations. The results of operations for these operating segments were as follows:
 
                                 
    Three Months Ended March 31,     Increase
 
    2010     2009     (Decrease)  
(In thousands, except percentages)  
 
Operating revenues and Earnings from unconsolidated affiliates
  $ 95,509     $ 155,468     $ (59,959 )     (39 %)
Adjusted income derived from operating activities
  $ 7,201     $ 18,954     $ (11,753 )     (62 %)
 
The decrease in operating results during the three months ended March 31, 2010 compared to the corresponding 2009 quarter resulted from declines in customer demand for our construction and logistics services in Alaska and lower capital equipment unit volumes and lower service and rental activity, partially offset by increased demand for directional drilling in the Canada and U.S. markets.

General and administrative expenses decreased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily as a result of significant decreases in wage-related expenses, including reductions in bonus accruals for executive management as a result of the new employment agreements effective April 1, 2009, and other cost-reduction efforts across all business units. In addition, these cost reductions have driven general and administrative expenses as a percentage of operating revenues down despite lower revenues during the current quarter.

Depreciation and amortization expense.  Depreciation and amortization expense increased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily as a result of projects completed in recent years under our expanded capital expenditure program that commenced in early 2005.
 
Depletion expense.  Depletion expense increased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter primarily as a result of increased natural gas production volumes beginning late 2009 and the current quarter.

Interest expense decreased during the three months ended March 31, 2010 compared to the corresponding 2009 quarter due to our lower long-term debt balance, primarily resulting from repurchases of approximately $1.2 billion par value of 0.94% senior exchangeable notes. The decrease was partially offset by interest expense from our 9.25% senior notes that were issued in mid-January 2009.

The amount of gains (losses) on sales and retirements of long-lived assets and other income (expense), net for the three months ended March 31, 2010 represented a net loss of $20.3 million and included: (i) foreign currency exchange losses of approximately $9.3 million, (ii) increased litigation expenses of $3.7 million, (iii) net losses on sales and retirements of long-lived assets of approximately $3.5 million, and (iv) losses of $2.8 million recognized on purchases of our 0.94% senior exchangeable notes due 2011.
 
The amount of gains (losses) on sales and retirements of long-lived assets and other income (expense), net for the three months ended March 31, 2009 included pre-tax gains of $15.7 million recognized on purchases of our 0.94% senior exchangeable notes and a gain of $2.7 million on the fair value of our range cap and floor derivative. These gains were partially offset by losses on retirements of long-lived assets of $1.4 million and increased litigation reserves of $1.8 million.

Effective income tax rate
    20 %     21 %     (1 )%     (5 %)
 
The decrease in our effective income tax rate during the three months ended March 31, 2010 compared to the corresponding 2009 quarter was a result of the proportion of income generated in the U.S. versus the non-U.S. jurisdictions in which we operate. Income generated in the U.S. is generally taxed at a higher rate than income generated in non-U.S. jurisdictions. We expect to incur a loss in the U.S. for the year which will produce a tax benefit.
 
We are subject to income taxes in the U.S. and numerous other jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. One of the most volatile factors in this determination is the relative proportion of our income or loss being recognized in high versus low tax jurisdictions. In the ordinary course of our business, there are many transactions and calculations for which the ultimate tax determination is uncertain. We are regularly under audit by tax authorities. Although we believe our tax estimates are reasonable, the final outcome of tax audits and any related litigation could be materially different than what is reflected in our income tax provisions and accruals. The results of an audit or litigation could materially affect our financial position, income tax provision, net income, or cash flows in the period or periods challenged.
 
Various bills have been introduced in Congress that could reduce or eliminate the tax benefits associated with our reorganization as a Bermuda company. Legislation enacted by Congress in 2004 provides that a corporation that reorganized in a foreign jurisdiction on or after March 4, 2003 be treated as a domestic corporation for U.S. federal income tax purposes. Nabors’ reorganization was completed June 24, 2002. There has been and we expect that there may continue to be legislation proposed by Congress from time to time which, if enacted, could limit or eliminate the tax benefits associated with our reorganization.
 
Because we cannot predict whether legislation will ultimately be adopted, no assurance can be given that the tax benefits associated with our reorganization will ultimately accrue to the benefit of Nabors and our

shareholders. It is possible that future changes to the tax laws (including tax treaties) could impact our ability to realize the tax savings recorded to date as well as future tax savings resulting from our reorganization.
 
Liquidity and Capital Resources
 
Cash Flows
 
Our cash flows depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Sustained increases or decreases in the price of natural gas or oil could have a material impact on these activities, and could also materially affect our cash flows. Certain sources and uses of cash, such as the level of discretionary capital expenditures, purchases and sales of investments, issuances and repurchases of debt and of our common shares are within our control and are adjusted as necessary based on market conditions. The following is a discussion of our cash flows for the three months ended March 31, 2010 and 2009.
 
Operating Activities.  Net cash provided by operating activities totaled $223.1 million during the three months ended March 31, 2010 compared to net cash provided by operating activities of $502.9 million during the corresponding 2009 quarter. Net cash provided by operating activities (“operating cash flows”) is our primary source of capital and liquidity. Factors affecting changes in operating cash flows are largely the same as those that affect net earnings, with the exception of noncash expenses such as depreciation and amortization, depletion, impairments, share-based compensation, deferred income taxes and our proportionate share of earnings or losses from unconsolidated affiliates. Net income adjusted for noncash components was approximately $256.5 million and $369.4 million for the three months ended March 31, 2010 and 2009, respectively. Additionally, changes in working capital items such as collection of receivables can be a significant component of operating cash flows. Changes in working capital items required $33.3 million in cash flows for the three months ended March 31, 2010 and provided $133.4 million in cash flows for the three months ended March 31, 2009.
 
Investing Activities.  Net cash used for investing activities totaled $134.9 million during the three months ended March 31, 2010 compared to net cash used for investing activities of $440.4 million during the corresponding 2009 quarter. During the three months ended March 31, 2010 and 2009, cash was used primarily for capital expenditures totaling $150.7 million and $390.5 million, respectively. Also during the three months ended March 31, 2010 and 2009, cash was derived from sales of investments, net of purchases, totaling $8.1 million and $5.4 million, respectively. During the three months ended March 31, 2009, cash totaling $62.1 million was contributed to our investments in unconsolidated affiliates.
 
Financing Activities.  Net cash used for financing activities totaled $111.5 million during the three months ended March 31, 2010 compared to net cash provided by financing activities of $478.1 million during the corresponding 2009 quarter. During the three months ended March 31, 2010, cash was used to purchase $106.8 million of our 0.94% senior exchangeable notes due 2011. During the three months ended March 31, 2009, cash was derived from the receipt of $1.1 billion in proceeds, net of debt issuance costs, from the January 2009 issuance of 9.25% senior notes due 2019. Also during 2009, cash totaling $572.3 million was used to purchase our 0.94% senior exchangeable notes and cash totaling $56.8 million was used to repay our 4.875% senior notes.
 
Future Cash Requirements
 
As of March 31, 2010, we had long-term debt, including current maturities, of $3.9 billion and cash and investments of $1.2 billion, including $99.2 million of long-term investments and other receivables. Long-term investments and other receivables included $91.4 million in oil and gas financing receivables.
 
Our 0.94% senior exchangeable notes mature in May 2011. Since 2008 and through March 31, 2010, we purchased $1.2 billion par value of these notes in the open market for cash totaling $1.0 billion, leaving approximately $1.6 billion par value outstanding. The balance of these notes will be reclassified to current debt in the second quarter of 2010. We believe our positive cash flow from operations in combination with our


40


Table of Contents

ability to access the capital markets will be sufficient to enable us to satisfy the payment obligation due in May 2011.
 
Our 0.94% senior exchangeable notes due 2011 provide that upon an exchange of these notes, we would be required to pay holders of the notes cash up to the principal amount of the notes and our common shares for any amount that the exchange value of the notes exceeds the principal amount of the notes. The notes cannot be exchanged until the price of our shares exceeds approximately $59.57 for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the previous calendar quarter; or during the five business days immediately following any ten consecutive trading day period in which the trading price per note for each day of that period was less than 95% of the product of the sale price of Nabors common shares and the then-applicable exchange rate for the notes; or upon the occurrence of specified corporate transactions set forth in the indenture. On April 28, 2010, the closing market price for our common stock was $21.44 per share. If any of the events described above were to occur and the notes were exchanged at a purchase price equal to 100% of the principal amount of the notes before maturity in May 2011, the required cash payment could have a significant impact on our level of cash and cash equivalents and investments available to meet our other cash obligations. Management believes that in the event the price of our shares were to exceed $59.57 for the required period of time, the holders of these notes would not be likely to exchange the notes as it would be more economically beneficial to them if they sold the notes to other investors on the open market. However, there can be no assurance that the holders would not exchange the notes.
 
As of March 31, 2010, we had outstanding purchase commitments of approximately $228.6 million, primarily for rig-related enhancements, construction and sustaining capital expenditures and other operating expenses. Capital expenditures over the next 12 months, including these outstanding purchase commitments, are currently expected to total approximately $.7 — $.8 billion, including currently planned rig-related enhancements, construction and sustaining capital expenditures. This amount could change significantly based on market conditions and new business opportunities. The level of our outstanding purchase commitments and our expected level of capital expenditures over the next 12 months represent a number of capital programs that are currently underway. These programs, which are nearing an end, have resulted in an expansion in the number of drilling and well-servicing rigs that we own and operate and consist primarily of land drilling and well-servicing rigs. The expansion of our capital expenditure programs to build new state-of-the-art drilling rigs has impacted a majority of our operating segments, most significantly within our U.S. Lower 48 Land Drilling, U.S. Land Well-servicing, Alaska, Canada and International operations.
 
We have historically completed a number of acquisitions and will continue to evaluate opportunities to acquire assets or businesses to enhance our operations. Several of our previous acquisitions were funded through issuances of our common shares. Future acquisitions may be paid for using existing cash or issuing debt or Nabors shares. Such capital expenditures and acquisitions will depend on our view of market conditions and other factors.
 
See our discussion of guarantees issued by Nabors that could have a potential impact on our financial position, results of operations or cash flows in future periods included below under Off-Balance Sheet Arrangements (Including Guarantees).
 
There have been no significant changes to our contractual cash obligations table which was included in our 2009 Annual Report.
 
We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, both in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
 
In July 2006, our Board of Directors authorized a share repurchase program under which we may repurchase up to $500 million of our common shares in the open market or in privately negotiated transactions. Through March 31, 2010, $464.5 million of our common shares had been repurchased under this program. As


41


Table of Contents

of March 31, 2010, we had the capacity to repurchase up to an additional $35.5 million of our common shares under the July 2006 share repurchase program.
 
See Note 10 — Commitments and Contingencies to the accompanying unaudited consolidated financial statements for discussion relating to (i) employment agreements, effective April 1, 2009, that could result in significant cash payments of $100 million and $50 million to Messrs. Isenberg and Petrello, respectively, by Nabors if their employment is terminated in the event of death or disability or cash payments of $100 million and $45 million to Messrs. Isenberg and Petrello, respectively, by Nabors if their employment is terminated without Cause or in the event of a Change in Control (as defined) and (ii) off-balance sheet arrangements (including guarantees).
 
Financial Condition and Sources of Liquidity
 
Our primary sources of liquidity are cash and cash equivalents, short-term and long-term investments and cash generated from operations. As of March 31, 2010, we had cash and investments of $1.2 billion (including $99.2 million of long-term investments and other receivables, inclusive of $91.4 million in oil and gas financing receivables) and working capital of $1.6 billion. This compares to cash and investments of $1.2 billion (including $100.9 million of long-term investments and other receivables, inclusive of $92.5 million in oil and gas financing receivables) and working capital of $1.6 billion as of December 31, 2009.
 
Our gross funded-debt-to-capital ratio was 0.40:1 as of March 31, 2010 and 0.41:1 as of December 31, 2009. Our net funded-debt-to-capital ratio was 0.32:1 as of March 31, 2010 and 0.33:1 as of December 31, 2009.
 
The gross funded-debt-to-capital ratio is calculated by dividing (x) funded debt by (y) funded debt plus deferred tax liabilities (net of deferred tax assets) plus capital. Funded debt is the sum of (1) short-term borrowings, (2) the current portion of long-term debt and (3) long-term debt. Capital is shareholders’ equity.
 
The net funded-debt-to-capital ratio is calculated by dividing (x) net funded debt by (y) net funded debt plus deferred tax liabilities (net of deferred tax assets) plus capital. Net funded debt is funded debt minus the sum of cash and cash equivalents and short-term and long-term investments and other receivables. Both of these ratios are used to calculate a company’s leverage in relation to its capital. Neither ratio measures operating performance or liquidity as defined by GAAP and, therefore, may not be comparable to similarly titled measures presented by other companies.
 
Our interest-coverage ratio was 5.5:1 as of March 31, 2010 and 6.2:1 as of December 31, 2009. The interest-coverage ratio is a trailing 12-month quotient of the sum of net income attributable to Nabors, interest expense, depreciation and amortization, depletion expense, impairments and other charges, income tax expense (benefit) and our proportionate share of writedowns from our unconsolidated oil and gas joint ventures less investment income (loss) divided by cash interest expense. This ratio is a method for calculating the amount of operating cash flows available to cover cash interest expense. The interest coverage ratio is not a measure of operating performance or liquidity defined by GAAP and may not be comparable to similarly titled measures presented by other companies.
 
We had four letter of credit facilities with various banks as of March 31, 2010. Availability under our credit facilities as of March 31, 2010 was as follows:

Our ability to access capital markets or to otherwise obtain sufficient financing is enhanced by our senior unsecured debt ratings as provided by Fitch Ratings, Moody’s Investors Service and Standard & Poor’s, which are currently “BBB+”, “Baa1” and “BBB+”, respectively, and our historical ability to access those markets as needed. While there can be no assurances that we will be able to access these markets in the future, we believe that we will be able to access them or otherwise obtain financing in order to satisfy any payment

obligation that might arise upon exchange or purchase of our notes and that any cash payment due, in addition to our other cash obligations, would not ultimately have a material adverse impact on our liquidity or financial position. In addition, Standard & Poor’s recently affirmed its “BBB+” credit rating, but revised its outlook to negative from stable in early 2009 due primarily to worsening industry conditions. A credit downgrade may impact our ability to access credit markets.
 
Our current cash and investments and projected cash flows from operations are expected to adequately finance our purchase commitments, our scheduled debt service requirements, and all other expected cash requirements for the next 12 months.
 
Other Matters
 
Recent Legislation and Actions
 
As of March 31, 2010, we had four rigs working in Venezuela and we continue to engage in drilling operations in Venezuela. As of November 2009, the economy in Venezuela was determined to be highly inflationary based upon the blended Consumer Price Index and National Consumer Price Index. In January 2010, the Venezuelan government devalued its currency and established a dual structure. The official exchange rate was devalued to 2.6 Bolivar Fuerte (“Bsf”) to each U.S. dollar for food and heavy machine importers and to 4.30 Bsf to each U.S. dollar for non-essential goods and services.
 
For the three months ended March 31, 2010, our consolidated statement of income included revenue totaling $9.1 million for services provided in Venezuela and $8.2 million of foreign currency exchange losses based on the official rate of 4.3 Bsf/U.S. dollar. As of March 31, 2010, accounts receivable denominated in Bsf of Venezuelan customers included USD$10.1 million adjusted for the currency devaluation discussed above.
 
A court in Algeria entered a judgment of approximately $19.7 million against us related to alleged customs infractions in 2009. We believe we did not receive proper notice of the judicial proceedings, and that the amount of the judgment is excessive. We have asserted the lack of legally required notice as a basis for challenging the judgment on appeal to the Algeria Supreme Court. Based upon our understanding of applicable law and precedent, we believe that this challenge will be successful. We do not believe that a loss is probable and have not accrued any amounts related to this matter. However, the ultimate resolution and the timing thereof are uncertain. If we are ultimately required to pay a fine or judgment related to this matter, the amount of the loss could range from approximately $140,000 to $19.7 million.
 
Recent Accounting Pronouncements
 
In December 2008, the SEC issued a final rule, “Modernization of Oil and Gas Reporting.” This rule revised some of the oil and gas reporting disclosures in Regulation S-K and Regulation S-X under the Securities Act and the Exchange Act, as well as Industry Guide 2. Effective December 31, 2009, the FASB issued revised guidance that substantially aligned the oil and gas accounting disclosures with the SEC’s final rule. The amendments were designed to modernize and update oil and gas disclosure requirements to align them with current practices and changes in technology. Additionally, this new accounting standard requires that entities use 12-month average natural gas and oil prices when calculating the quantities of proved reserves and performing the full-cost ceiling test calculation. The new standard also clarified that an entity’s equity-method investments must be considered in determining whether it has significant oil and gas activities. The disclosure requirements were effective for registration statements filed on or after January 1, 2010 and for annual financial statements filed on or after January 1, 2010. The FASB provided a one-year deferral of the disclosure requirements if an entity became subject to the requirements because of a change to the definition of significant oil and gas activities. When operating results from our wholly owned oil and gas activities are considered with operating results from our unconsolidated oil and gas joint ventures, which we account for under the equity method of accounting, we have significant oil and gas activities under the new definition. In line with the one-year deferral, we will provide the oil and gas disclosures for annual financial statements for periods beginning after December 31, 2009 or registration statements filed on or after January 1, 2011.

Effective January 1, 2010, we adopted the revised provisions relating to consolidation of variable interest entities within the Consolidations Topic of the ASC. The revised provisions replaced the quantitative approach to identify a variable interest entity with a qualitative approach that focuses on an entity’s control and ability to direct the variable interest entity’s activities. The application of these provisions did not have a material impact on our consolidated financial statements.
 
Critical Accounting Estimates
 
We disclosed our critical accounting estimates in our 2009 Annual Report and there have been no changes to those estimates.
 
ITEM 3.   Quantitative and Qualitative Disclosures About Market Risk
 
We may be exposed to market risk through changes in interest rates and foreign currency risk arising from our operations in international markets as discussed in our 2009 Annual Report and above, under “Recent Legislation and Actions.”
 
ITEM 4.   Controls and Procedures
 
(a) Disclosure Controls and Procedures. We maintain a set of disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. We have investments in certain unconsolidated entities that we do not control or manage. Because we do not control or manage these entities, our disclosure controls and procedures with respect to such entities are necessarily more limited than those we maintain with respect to our consolidated subsidiaries.
 
Our management, with the participation of our Chairman and Chief Executive Officer and principal accounting and financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on their evaluation, our Chairman and Chief Executive Officer and principal accounting and financial officer have concluded that, as of the end of such period, our disclosure controls and procedures are effective, at the reasonable assurance level, in (i) recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed in the reports that we file or submit under the Exchange Act and (ii) ensuring that information required to be disclosed in such reports is accumulated and communicated to our management, including our Chairman and Chief Executive Officer and principal accounting and financial officer, as appropriate to allow timely decisions regarding required disclosure.
 
(b) Changes in Internal Control Over Financial Reporting. There have not been any changes in our internal control over financial reporting (identified in connection with the evaluation required by paragraph (d) in Rules 13a-15 and 15d-15 under the Exchange Act) during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
 
PART II OTHER INFORMATION
 
Item 1.   Legal Proceedings
 
Nabors and its subsidiaries are defendants or otherwise involved in a number of lawsuits in the ordinary course of business. We estimate the range of our liability related to pending litigation when we believe the amount and range of loss can be estimated. We record our best estimate of a loss when the loss is considered probable. When a liability is probable and there is a range of estimated loss with no best estimate in the range, we record the minimum estimated liability related to the lawsuits or claims. As additional information becomes available, we assess the potential liability related to our pending litigation and claims and revise our estimates. Due to uncertainties related to the resolution of lawsuits and claims, the ultimate outcome may differ from our estimates. In the opinion of

management and based on liability accruals provided, our ultimate exposure with respect to these pending lawsuits and claims is not expected to have a material adverse effect on our consolidated financial position or cash flows, although they could have a material adverse effect on our results of operations for a particular reporting period.
 
On July 5, 2007, we received an inquiry from the U.S. Department of Justice relating to its investigation of one of our vendors and compliance with the Foreign Corrupt Practices Act. The inquiry relates to transactions with and involving Panalpina, which provides freight forwarding and customs clearance services to some of our affiliates. To date, the inquiry has focused on transactions in Kazakhstan, Saudi Arabia, Algeria and Nigeria. The Audit Committee of our Board of Directors engaged outside counsel to review some of our transactions with this vendor, has received periodic updates at its regularly scheduled meetings, and the Chairman of the Audit Committee has received updates between meetings as circumstances warrant. The investigation includes a review of certain amounts paid to and by Panalpina in connection with obtaining permits for the temporary importation of equipment and clearance of goods and materials through customs. Both the SEC and the Department of Justice have been advised of our investigation. The ultimate outcome of this investigation or the effect of implementing any further measures that may be necessary to ensure full compliance with applicable laws cannot be determined at this time.
 
A court in Algeria entered a judgment of approximately $19.7 million against us related to alleged customs infractions in 2009. We believe we did not receive proper notice of the judicial proceedings and that the amount of the judgment is excessive. We have asserted the lack of legally required notice as a basis for challenging the judgment on appeal to the Algeria Supreme Court. Based upon our understanding of applicable law and precedent, we believe that this challenge will be successful. We do not believe that a loss is probable and have not accrued any amounts related to this matter. However, the ultimate resolution and the timing thereof are uncertain. If we are ultimately required to pay a fine or judgment related to this matter, the amount of the loss could range from approximately $140,000 to $19.7 million.
 
Item 1A.   Risk Factors
 
There have been no material changes during the three months ended March 31, 2010 to our “Risk Factors” as discussed in our 2009 Annual Report.
 
Item 2.   Unregistered Sales of Equity Securities and Use of Proceeds
 
We withheld the following shares of our common stock to satisfy tax withholding obligations during the three months ended March 31, 2010 from the distributions described below. These shares may be deemed to be “issuer purchases” of shares that are required to be disclosed pursuant to this Item:

(1) Shares were withheld from employees to satisfy certain tax withholding obligations due in connection with grants of stock under our 2003 Employee Stock Plan and option exercises from our 1997 Executive Incentive Plan. Both the 2003 Employee Stock Plan and 1997 Executive Incentive Plan provide for the withholding of shares to satisfy tax obligations, but do not specify a maximum number of shares that can be withheld for this purpose. These shares were not purchased as part of a publicly announced program to purchase common shares.
 
(2) In July 2006, our Board of Directors authorized a share repurchase program under which we may repurchase up to $500 million of our common shares in the open market or in privately negotiated transactions. Through March 31, 2010, $464.5 million of our common shares had been repurchased under this program. As of March 31, 2010, we had the capacity to repurchase up to an additional $35.5 million of our common shares under the July 2006 share repurchase program.
