NABORS INDUSTRIES LTD. AND SUBSIDIARIES
 
 
Note 1  Nature of Operations
 
Nabors is the largest land drilling contractor in the world, with approximately 600 land drilling rigs. We conduct oil, gas and geothermal land drilling operations in the U.S. Lower 48 states, Alaska, Canada, South and Central America, the Middle East, the Far East and Africa. We are also one of the largest land well-servicing and workover contractors in the United States and Canada. We own approximately 590 land workover and well-servicing rigs in the United States, primarily in the southwestern and western United States, and approximately 215 land workover and well-servicing rigs in Canada. Nabors is a leading provider of offshore platform workover and drilling rigs, and owns 46 platform, 19jack-upunits and five barge rigs in the United States and multiple international markets. These rigs provide well-servicing, workover and drilling services. We have a 50% ownership interest in a joint venture in Saudi Arabia, which owns 18 rigs. We also offer a wide range of ancillary well-site services, including engineering, transportation, construction, maintenance, well logging, directional drilling, rig instrumentation, data collection and other support services in selected domestic and international markets. We time charter a fleet of 29 marine transportation and supply vessels, which provide transportation of drilling materials, supplies and crews for offshore operations. During the first quarter of 2006 we began to offer logistics services for onshore drilling and well-servicing operations in Canada using helicopters and fixed-winged aircraft purchased from Airborne Energy Solutions Ltd. on January 3, 2006 (Note 4). We manufacture and lease or sell top drives for a broad range of drilling applications, directional drilling systems, rig instrumentation and data collection equipment, pipeline handling equipment and rig reporting software. We also have made selective investments in oil and gas exploration, development and production activities.
 
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 a category labeled Oil and Gas for segment reporting purposes. Our operating segments engaged in marine transportation and supply services, drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software, and construction and logistics operations are aggregated in a category labeled Other Operating Segments for segment reporting purposes.
 
As used in this Report, the “Company,” “we,” “us,” “our” and “Nabors” means Nabors Industries Ltd. and, where the context requires, includes our subsidiaries.
 
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 U.S. Securities and Exchange Commission, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted. Therefore, these financial statements should be read along with our Annual Report onForm 10-Kfor the year ended December 31, 2005. In our management’s opinion, the consolidated financial statements contain all adjustments necessary to present fairly our financial position as of September 30, 2006 and the results of our operations for the three and nine months ended September 30, 2006 and 2005, and our cash flows for the nine months ended September 30, 2006 and 2005, in accordance with GAAP. Interim results for the three and nine months ended September 30, 2006 may not be indicative of results that will be realized for the full year ending December 31, 2006.
 
On December 13, 2005, our Board of Directors approved atwo-for-onestock split of our common shares to be effectuated in the form of a stock dividend. The stock dividend was distributed on April 17, 2006 to shareholders of record on March 31, 2006 (see Note 7). All common share, per share, stock option and restricted stock amounts

NABORS INDUSTRIES LTD. AND SUBSIDIARIES
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

included in the accompanying Consolidated Financial Statements and related notes have been restated to reflect the effect of the stock split.
 
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, 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, all majority-owned subsidiaries, and all non-majority owned subsidiaries required to be consolidated under Financial Accounting Standards Board (FASB) Interpretation No. 46R, which are not material to our financial position, results of operations or cash flows. 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 their operating and financial policies, are accounted for using the equity method. Our share of the net income of these entities is recorded as Earnings from unconsolidated affiliates in our consolidated statements of income, and our investment in these entities is carried as a single amount in our consolidated balance sheets. Investments in net assets of unconsolidated affiliates accounted for using the equity method totaled $91.2 million and $71.2 million as of September 30, 2006 and December 31, 2005, respectively, and are included in other long-term assets in our consolidated balance sheets. Similarly, investments in certain offshore funds classified as non-marketable are accounted for using the equity method of accounting based on our ownership interest in each fund. Our share of the gains and losses of these funds is recorded in investment income in our consolidated statements of income and our investments in these funds are included in long-term investments in our consolidated balance sheets.
 
Recent Accounting Pronouncements
 
In June 2006 the FASB issued Interpretation No. 48 (FIN 48), “Accounting for Uncertainty in Income Taxes,” which prescribes a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. Under FIN 48, the financial statements will reflect expected future tax consequences of such positions presuming the taxing authorities’ full knowledge of the position and all relevant facts, but without considering time values. FIN 48 is likely to cause greater volatility in income statements as more items are recognized discretely within income tax expense. Application of FIN 48 is required in financial statements effective for periods beginning after December 15, 2006. FIN 48 revises disclosure requirements and will require an annual tabular roll-forward of unrecognized tax benefits. We expect to adopt FIN 48 beginning January 1, 2007. We are currently evaluating the impact that this interpretation may have on our consolidated financial statements. Any adjustment required as a result of the adoption of FIN 48 will be recorded to retained earnings.
 
In September 2006 the FASB issued SFAS No. 157, “Fair Value Measurements.” This statement establishes a framework for measuring fair value within generally accepted accounting principles and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The provisions of SFAS 157 should be applied prospectively as of the beginning of the fiscal year in which SFAS 157 is initially applied, except in limited circumstances. We expect to adopt SFAS 157 beginning January 1, 2008. We are currently evaluating the impact that this interpretation may have on our consolidated financial statements.
 
In September 2006 the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans an amendment of FASB Nos. 87, 88, 106 and 132(R).” This statement requires companies to recognize a net liability or asset to report the funded status of their defined benefit pension and other

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

postretirement benefit plans in its statement of financial position and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. SFAS 158 is required to be applied in financial statements effected for periods ending after December 15, 2006. We will adopt SFAS 158 as of December 31, 2006. We do not believe that the adoption of SFAS 158 will have a material impact on our financial position, results of operations or cash flows.
 
Note 3  Share-Based Compensation
 
The Company has several stock-based employee compensation plans, which are more fully described in Note 9 in the Company’s 2005 Annual Report onForm 10-K.Prior to January 1, 2006, we accounted for awards granted under those plans following the recognition and measurement principles of Accounting Principles Bulletin (APB) Opinion No. 25, “Accounting for Stock Issued to Employees,” (APB 25) and related interpretations. Under APB 25, no compensation expense was reflected in net income for the Company’s stock options, as all options granted under those plans had an exercise price equal to the market value of the underlying common shares on the date of grant. The pro forma effects on income for stock options were instead disclosed in a footnote to the financial statements. Compensation expense was recorded in the income statement for restricted stock grants over the vesting period of the award.
 
Effective January 1, 2006, we adopted the fair value recognition provisions of FASB Statement of Financial Accounting Standard No. 123(R), “Share-Based Payments,”(SFAS 123-R),using the modified prospective application method. Under this transition method, the Company will record compensation expense for all stock option awards granted after the date of adoption and for the unvested portion of previously granted stock option awards that remain outstanding at the date of adoption. The amount of compensation cost recognized was based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123. Results for prior periods have not been restated.
 
As a result of adoptingSFAS 123-Ron January 1, 2006, Nabors’ income before income taxes and net income for the three months ended September 30, 2006 were $4.2 million and $3.3 million lower, respectively and $14.0 million and $10.8 million lower for the nine months ended September 30, 2006, respectively, than if we had continued to account for share-based compensation under APB 25. Basic and diluted earnings per share for the three months ended September 30, 2006 would have been $1.07 and $1.03, respectively and $2.69 and $2.60, respectively, for the nine months ended September 30, 2006, if we had continued to account for share-based compensation under APB 25, compared to reported basic and diluted earnings per share of $1.05 and $1.02, respectively, for the three months ended September 30, 2006 and $2.65 and $2.57, respectively, for the nine months ended September 30, 2006.
 
Compensation expense related to awards of restricted stock was recognized before the adoption ofSFAS 123-R.Compensation expense for restricted stock totaled $3.2 million and $1.5 million for the three months ended September 30, 2006 and 2005, respectively, and $8.6 million and $3.4 million for the nine months ended September 30, 2006 and 2005, respectively, and is included in direct costs and general and administrative expenses in our consolidated statements of income. Total stock-based compensation expense, which includes both stock options and restricted stock totaled $7.5 million and $22.6 million for the three and nine months ended September 30, 2006, respectively. Stock-based compensation expense has been allocated to our various operating segments (Note 11).
 
Prior to adoption ofSFAS 123-R,Nabors presented all tax benefits of deductions resulting from the exercise of options as operating cash flows in the Consolidated Statements of Cash Flows.SFAS 123-Rrequires the cash flows resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) to be classified as financing cash flows. The actual tax benefit realized from options exercised during the nine months ended September 30, 2006 was $4.3 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Under the provisions ofSFAS 123-R,the recognition of unearned compensation, a contra-equity account representing the amount of unrecognized restricted stock compensation expense, is no longer required. Therefore, in the first quarter of 2006 the Unearned Compensation amount that was included in our December 31, 2005 consolidated balance sheet in the amount of $15.6 million was reduced to zero with a corresponding decrease to Capital in Excess of Par Value.
 
Prior Period Pro Forma Presentation
 
Under the modified prospective application method, results for prior periods have not been restated to reflect the effects of implementingSFAS 123-R.The following pro forma information, as required by SFAS No. 148 “Accounting for Stock-Based Compensation — an Amendment to FAS 123,” is presented for comparative purposes and illustrates the effect on our net income and earnings per share as if we had applied the provisions ofSFAS 123-Rbeginning on January 1, 2005:

Stock Option Plans
 
Stock option awards under the Company’s various stock-based employee compensation plans are granted at prices equal to the fair market value of the shares on the date of the grant. Options granted under the plan generally vest in varying periodic installments after one year. In the case of certain key executives, options granted under the plans may vest immediately on the grant date. Options granted under the plan expire ten years from the date of grant.
 
The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses the assumptions for the risk-free interest rate, volatility, dividend yield and the expected term of the options. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equal to the expected term of the option. Expected volatilities are based on implied volatilities from traded options on the Nabors’ common shares, historical volatility of Nabors’ common shares, and other factors. We do not assume any dividend yield, as the Company does not pay dividends. We use historical data to estimate the expected term of the options and employee terminations within the option-pricing model; separate groups of employees that have

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

similar historical exercise behavior are considered separately for valuation purposes. The expected term of the options represents the period of time that the options granted are expected to be outstanding.
 
We also consider an estimated forfeiture rate when determining the fair value of each award, and we only recognize compensation cost for those shares that are expected to vest, on a straight-line basis over the requisite service period of the award, which is generally the vesting term of three to four years. The forfeiture rate is based on historical experience. Estimated forfeitures will be adjusted to reflect actual forfeitures in future periods.
 
There were no stock options granted, and as a result, no fair value determinations were made during the nine months ended September 30, 2006. Stock option transactions under the Company’s various stock-based employee compensation plans during the nine months ended September 30, 2006, is presented below:

Restricted Stock and Restricted Stock Units
 
Our stock compensation plans allow grants of restricted stock. Restricted stock is issued on the grant date, but is restricted as to transferability. Restricted stock vests in varying periodic installments ranging up to 3 to 4 years.

Note 4  Acquisitions
 
On January 3, 2006, we completed an acquisition of 1183011 Alberta Ltd., a wholly-owned subsidiary of Airborne Energy Solutions Ltd., through the purchase of all common shares outstanding for cash for a total purchase price of Cdn. $41.7 million (U.S. $35.8 million). In addition, we assumed debt, net of working capital, totaling approximately Cdn. $10.0 million (U.S. $8.6 million). Nabors Blue Sky Ltd. (formerly 1183011 Alberta Ltd.) owns 42 helicopters and fixed-wing aircraft and owns and operates a fleet of heliportable well-service equipment. The purchase price has been allocated based on preliminary estimates of the fair value of assets acquired and liabilities assumed as of the acquisition date and resulted in goodwill of approximately U.S. $18.8 million. The purchase price allocation is subject to adjustment as additional information becomes available and will be finalized by December 31, 2006.
 
On May 31, 2006, we completed an acquisition of Pragma Drilling Equipment Ltd.’s business, which manufactures catwalks, iron roughnecks and other related oilfield equipment, through an asset purchase consisting primarily of intellectual property for a total purchase price of Cdn. $36.4 million (U.S. $33.0 million). Additional cash purchase consideration, up to a maximum of Cdn. $12 million (U.S. $10.8 million), will be due if certain specified financial performance targets are achieved over a one-year period commencing on June 30, 2006. The purchase price has been allocated based on preliminary estimates of the fair market value of assets acquired and liabilities assumed as of the acquisition date and resulted in goodwill of approximately U.S. $2.0 million. The purchase price allocation is subject to adjustments as additional information becomes available and will be finalized by December 31, 2006. Any contingent consideration payable in the future will be recorded as goodwill.
 
On September 21, 2006, we entered into a Letter of Intent to acquire the Moncla Companies for an undisclosed amount. Moncla owns six barge rigs, 50 workover and well-servicing rigs, 13 truck-mounted swabbing and testing units, rental equipment, various auxiliary equipment and real estate. Moncla’s headquarters, central training and maintenance facility and principal operations are located in Lafayette, Louisiana with extended operating yards located in Mississippi and Southeast Texas. The transaction is expected to be completed during 2006.
 
Note 5  Debt
 
On May 23, 2006, Nabors Industries, Inc. (“Nabors Delaware”), our wholly-owned subsidiary, completed a private placement of $2.5 billion aggregate principal amount of 0.94% senior exchangeable notes due 2011 that are fully and unconditionally guaranteed by us. On June 8, 2006, the initial purchasers exercised their option to purchase an additional $250 million of the 0.94% senior exchangeable notes due 2011, increasing the aggregate issuance of such notes to $2.75 billion. Nabors Delaware sold the notes to the initial purchasers in reliance on the exemption from registration provided by Section 4(2) of the Securities Act of 1933, as amended. The notes were reoffered by the initial purchasers of the notes to qualified institutional buyers under Rule 144A of the Securities Act. Nabors and Nabors Delaware filed a registration statement onForm S-3pursuant to the Securities Act with respect to resale of the notes and shares received in exchange for the notes on August 21, 2006. The notes bear interest at a rate of 0.94% per year payable semiannually on May 15 and November 15 of each year, beginning on November 15, 2006. Debt issuance costs of $28.3 million were capitalized in connection with the issuance of the notes in other long-term assets in our consolidated balance sheet and are being amortized through May 2011.
 
The notes are exchangeable into cash and, if applicable, Nabors’ common shares based on an exchange rate of the equivalent value of 21.8221 Nabors’ common shares per $1,000 principal amount of notes (which is 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 and prior thereto only under the following circumstances: (1) during any calendar quarter (and only during such calendar quarter), if the closing price of Nabors’ common shares for at least 20 trading days in the 30 consecutive trading days ending on the last

NABORS INDUSTRIES LTD. AND SUBSIDIARIES
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

trading day of the immediately preceding calendar quarter is more than 130% of the applicable exchange rate; (2) during the five business day period after 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 closing sale price of Nabors’ common shares and the exchange rate of the note; and (3) upon the occurrence of specified corporate transactions set forth in the indenture.
 
The notes are unsecured and are effectively junior in right of payment to any of Nabors Delaware’s future secured debt. The notes will rank equally with any of Nabors Delaware’s other existing and future unsubordinated debt and will be senior in right of payment to any of Nabors Delaware’s future subordinated debt. Our guarantee of the note is unsecured and ranks equal in right of payments to all of our unsecured and unsubordinated indebtedness from time to time outstanding. Holders of the notes, who exchange their notes in connection with a change in control, as defined in the indenture, may be entitled to a make-whole premium in the form of an increase in the exchange rate. Additionally, in the event of a change in control, the holders of the notes may require Nabors Delaware to purchase all or a portion of their notes at a purchase price equal to 100% of the principal amount of notes, plus accrued and unpaid interest, if any. Upon exchange of the notes, a holder will receive for each note exchanged an amount in cash equal to the lesser of (i) $1,000 or (ii) the exchange value, determined in the manner set forth in the indenture. In addition, if the exchange value exceeds $1,000 on the exchange date, a holder will also receive a number of Nabors’ common shares for the exchange value in excess of $1,000 equal to such excess divided by the exchange price.
 
In connection with the sale of the notes, Nabors Delaware entered into exchangeable note hedge transactions with respect to our common shares. The call options are designed to cover, subject to customary anti-dilution adjustments, the net number of our common shares that would be deliverable to exchanging noteholders in the event of an exchange of the notes. Nabors Delaware paid an aggregate amount of approximately $583.6 million of the proceeds from the sale of the notes to acquire the call options.
 
Nabors also entered into separate warrant transactions at the time of the sale of the notes whereby we sold warrants which give the holders the right to acquire approximately 60.0 million of our common shares at a strike price of $54.64 per share. On exercise of the warrants, we have the option to deliver cash or our common shares equal to the difference between the then market price and strike price. All of the warrants will be exercisable and will expire on August 15, 2011. We received aggregate proceeds of approximately $421.2 million from the sale of the warrants and used $353.4 million of the proceeds to purchase 10.0 million of Nabors’ common shares.
 
The purchased call options and sold warrants are separate contracts entered into by Nabors and Nabors Delaware with two financial institutions, and are not part of the terms of the notes and will not affect the holders’ rights under the notes. The purchased call options are expected to offset the potential dilution upon exchange of the notes in the event that the market value per share of our common shares at the time of exercise is greater than the strike price of the purchased call options, which corresponds to the initial exchange price of the notes and is simultaneously subject to certain customary adjustments. The warrants will effectively increase the exchange price of the notes to $54.64 per share of our common shares, from the perspective of Nabors, representing a 55% premium based on the last reported bid price of $35.25 per share on May 17, 2006. In accordance with Emerging Issues Task Force IssueNo. 00-19,“Accounting for Derivative Financial Instruments Indexed To and Potentially Settled In, a Company’s Own Stock” and SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity,” we recorded the exchangeable note hedge and warrants in capital in excess of par value as of the transaction date, and will not recognize subsequent changes in fair value. We also recognized a deferred tax asset of $215.9 million in the second quarter of 2006 for the effect of the future tax benefits related to the exchangeable note hedge.
 
We intend to use the remaining proceeds of the offering for general corporate purposes, which may include capital expenditures, acquisitions, retirement of other indebtedness and additional repurchases of Nabors’ common shares.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

On May 23, 2006, Nabors International Management Ltd. (“NIML”), a direct wholly-owned subsidiary of Nabors borrowed from affiliates of the initial purchasers $650 million pursuant to a90-daysenior unsecured loan. The proceeds of the loan were used to purchase 18.4 million of Nabors’ common shares, which are held in treasury. The unsecured loan was paid in full on June 30, 2006.
 
On February 6, 2006, we redeemed 93% of our $1.2 billion zero coupon senior convertible debentures due 2021 for a total redemption price of $769.8 million; an amount equal to the issue price of $679.9 million plus accrued original issue discount of $89.9 million to the date of repurchase. We treat the redemption price, including accrued original discount, on our convertible debt instruments as a financing activity for purposes of reporting cash flows in our consolidated statements of cash flows. The principal amount of these debentures outstanding subsequent to this redemption totaled $57.0 million. The original principal amount of these debentures upon issuance was $1.381 billion, of which $180.8 million had been redeemed prior to 2005.
 
Note 6  Income Taxes
 
Our effective income tax rate was 26.8% and 30.2% during the three and nine months ended September 30, 2006, respectively, compared to 26.2% and 25.1% during the three and nine months prior year periods. The increase in our effective income tax rate resulted from a higher proportion of our taxable income being generated in the U.S. during the three and nine months ended September 30, 2006 compared to the prior year periods. Income generated in the U.S. is generally taxed at a higher rate than in international jurisdictions in which we operate. Additionally, during the three months ended June 30, 2006, we recorded a $36.2 million current tax expense relating to the redemption of common shares held by a foreign parent of a U.S. based Nabors’ subsidiary. This income tax expense was partially offset by an approximate $20.5 million deferred tax benefit recorded as a result of changes in Canadian laws that incrementally reduce statutory tax rates for both federal and provincial taxes over the next four years.
 
Note 7  Common Shares
 
During the nine months ended September 30, 2006, we repurchased 40.2 million of our common shares in the open market for $1.4 billion. We retired 17.9 million shares during the nine months ended September 30, 2006 and held 22.2 million of these shares in treasury. During the nine months ended September 30, 2005, we repurchased and retired 3.0 million of our common shares in the open market for $80.6 million.
 
On December 13, 2005, our Board of Directors approved atwo-for-onestock split of our common shares to be effectuated in the form of a stock dividend. The stock split was subject to the approval by our shareholders of a proposal to amend our Amended and Restated Bye-Laws to increase the authorized share capital of Nabors by the creation of additional common shares. This proposal was approved by our shareholders in a Special Meeting of Shareholders on March 30, 2006. The stock dividend was distributed on April 17, 2006 to shareholders of record on March 31, 2006. For all balance sheets presented, capital in excess of par value was reduced by $.2 million and common shares were increased by $.2 million.
 
Note 8  Commitments and Contingencies
 
Commitments
 
Employment Contracts
 
Nabors’ Chairman and Chief Executive Officer, Eugene M. Isenberg, and its Deputy Chairman, President and Chief Operating Officer, Anthony G. Petrello, have employment agreements which were amended and restated effective October 1, 1996 and which currently are due to expire on September 30, 2010.
 
Mr. Isenberg’s employment agreement was originally negotiated with a creditors committee in 1987 in connection with the reorganization proceedings of Anglo Energy, Inc., which subsequently changed its name to

Table of Contents

 
NABORS INDUSTRIES LTD. AND SUBSIDIARIES
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Nabors. These contractual arrangements subsequently were approved by the various constituencies in those reorganization proceedings, including equity and debt holders, and confirmed by the United States Bankruptcy Court.
 
Mr. Petrello’s employment agreement was first entered into effective October 1, 1991. Mr. Petrello’s employment agreement was agreed upon as part of arm’s length negotiations with the Board before he joined Nabors in October 1991, and was reviewed and approved by the Compensation Committee of the Board and the full Board of Directors at that time.
 
The employment agreements for Messrs. Isenberg and Petrello were amended in 1994 and 1996. These amendments were approved by the Compensation Committee of the Board and the full Board of Directors at that time.
 
The employment agreements provide for an initial term of five years with an evergreen provision which automatically extended the agreement for an additional one-year term on each anniversary date, unless Nabors provided notice to the contrary ten days prior to such anniversary. The Board of Directors in March 2006 exercised its election to fix the expiration date of the employment agreements for Messrs. Isenberg and Petrello, and accordingly, these agreements will expire at the end of their current term at September 30, 2010.
 
In addition to a base salary, the employment agreements provide for annual cash bonuses in an amount equal to 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. Isenberg’s cash bonus formula originally was set at 10% in excess of a 10% return on shareholders’ equity and he has voluntarily reduced it over time to its 6% in excess of 15% level.) Mr. Petrello’s bonus is subject to a minimum of $700,000 per year. In 15 of the last 16 years, Mr. Isenberg has agreed voluntarily to accept a lower annual cash bonus (i.e., an amount lower than the amount provided for under his employment agreement) in light of his overall compensation package. Mr. Petrello has agreed voluntarily to accept a lower annual cash bonus (i.e., an amount lower than the amount provided for under his employment agreement) in light of his overall compensation package in 13 of the last 15 years. For 2005, the annual cash bonuses for Messrs. Isenberg and Petrello pursuant to the formula described in their employment agreements were $41.2 million and $13.7 million, respectively; but in light of their overall compensation package (including significant stock option grants and restricted stock awards), they agreed to accept cash bonuses in the amounts of $3 million and $1.5 million, respectively.
 
Mr. Isenberg voluntarily agreed to amend his employment agreement in March 2006 (the “2006 Amendment”). Under the 2006 Amendment, Mr. Isenberg agreed to reduce the annual cash bonus to an amount equal to 3% of Nabors’ net cash flow (as defined in his employment agreement) in excess of 15% of the average shareholders’ equity for 2006. For 2007 through the expiration date of the employment agreement, the annual cash bonus will return to 6% of Nabors’ net cash flow in excess of 15% of the average shareholders’ equity for each fiscal year.
 
Messrs. Isenberg and Petrello also are eligible for awards under Nabors’ equity plans and 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.
 
Termination in the event of death, disability, or termination without cause.   In the event that either Mr. Isenberg’s or Mr. Petrello’s employment agreement is terminated (i) upon death or disability (as defined in the respective employment agreements), (ii) by Nabors prior to the expiration date of the employment agreement for any reason other than for Cause (as defined in the respective employment agreements) or (iii) by either individual for Constructive Termination Without Cause (as defined in the respective employment agreements), each would be entitled to receive within 30 days of the triggering event (a) all base salary which would have been payable through the expiration date of the contract or three times his then current base salary, whichever is greater; plus (b) the greater of (i) all annual cash bonuses which would have been payable through the expiration date; (ii) three times the highest bonus (including the imputed value of grants of stock awards and stock options), paid during the last three fiscal years prior to termination; or (iii) three times the highest annual cash bonus payable for each of the three

previous fiscal years prior to termination, regardless of whether the amount was paid. In computing any amount due under (b)(i) and (iii) above, the calculation is made without regard to the 2006 Amendment reducing Mr. Isenberg’s bonus percentage as described above. If, by way of example, these provisions had applied at September 30, 2006, Mr. Isenberg would have been entitled to a payment of approximately $203 million, subject to a “true-up” equal to the amount of cash bonus he would have earned under the formula during the remaining term of the agreement, based upon actual results, but would not be less than approximately $203 million. Similarly, with respect to Mr. Petrello, had these provisions applied at September 30, 2006, Mr. Petrello would have been entitled to a payment of approximately $103 million, subject to a “true-up” equal to the amount of cash bonus he would have earned under the formula during the remaining term of the agreement, based upon actual results, but would not be less than approximately $103 million. These payment amounts are based on historical data and are not intended to be estimates of future payments required under the agreements. Depending upon future operating results, thetrue-upcould result in the payment of amounts which are significantly higher. In addition, the affected individual is entitled to receive (a) any unvested restricted stock outstanding, which shall immediately and fully vest; (b) any unvested outstanding stock options, which shall immediately and fully vest; (c) 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 shall be continued through the later of the expiration date or three years after the termination date; (d) continued participation in medical, dental and life insurance coverage until the executive receives equivalent benefits or coverage through a subsequent employer or until the death of the executive or his spouse, whichever is later; and (e) any other or additional benefits in accordance with applicable plans and programs of Nabors. For Mr. Isenberg, as of September 30, 2006, the value of unvested restricted stock was approximately $9.9 million and the value ofin-the-moneyunvested stock options was approximately $4.3 million. For Mr. Petrello, as of September 30, 2006, the value of unvested restricted stock was approximately $5.0 million and the value ofin-the-moneyunvested stock options was approximately $2.2 million. Estimates of the cash value of Nabors’ obligations to Messrs. Isenberg and Petrello under (c), (d) and (e) above are included in the payment amounts above.
 
The Board of Directors in March 2006 exercised its election to fix the expiration date of the employment agreements for Messrs. Isenberg and Petrello. Messrs. Isenberg and Petrello have informed the Board of Directors that they have reserved their rights under their employment agreements with respect to the notice setting the expiration dates of their employment agreements, including whether such notice could trigger an acceleration of certain payments pursuant to their employment agreements.
 
Termination in the event of a Change in Control.   In the event that Messrs. Isenberg’s or Petrello’s termination of employment is related to a Change in Control (as defined in their respective employment agreements), they would be entitled to receive a cash amount equal to the greater of (a) one dollar less than the amount that would constitute an “excess parachute payment” as defined in Section 280G of the Internal Revenue Code, or (b) the cash amount that would be due in the event of a termination without cause, as described above. If, by way of example, there was a change of control event that applied on September 30, 2006, then the payments to Messrs. Isenberg and Petrello would be approximately $203 million and $103 million, respectively. These payment amounts are based on historical data and are not intended to be estimates of future payments required under the agreements. Depending upon future operating results, the true-upcould result in the payment of amounts which are significantly higher. In addition, they would receive (a) any unvested restricted stock outstanding, which shall immediately and fully vest; (b) any unvested outstanding stock options, which shall immediately and fully vest; (c) 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 shall be continued through the later of the expiration date or three years after the termination date; (d) continued participation in medical, dental and life insurance coverage until the executive receives equivalent benefits or coverage through a subsequent employer or until the death of the executive or his spouse, whichever is later; and (e) any other or additional benefits in accordance with applicable plans and programs of Nabors. For Mr. Isenberg, as of September 30, 2006, the value of unvested restricted stock was approximately $9.9 million and the value ofin-the-moneyunvested stock options

was approximately $4.3 million. For Mr. Petrello, as of September 30, 2006, the value of unvested restricted stock was approximately $5.0 million and the value ofin-the-moneyunvested stock options was approximately $2.2 million. The cash value of Nabors’ obligations to Messrs. Isenberg and Petrello under (c), (d) and (e) above are included in the payment amounts above. Also, they would receive additional stock options immediately exercisable for five years to acquire a number of shares of common stock equal to the highest number of options granted during any fiscal year in the previous three fiscal years, at an option exercise price equal to the average closing price during the 20 trading days prior to the event which resulted in the change of control. If, by way of example, there was a change of control event that applied at September 30, 2006, Mr. Isenberg would have received 3,366,666 options valued at approximately $36 million and Mr. Petrello would have received 1,683,332 options valued at approximately $18 million, in each case based upon a Black Scholes analysis. Finally, in the event that an excise tax was applicable, they would receive agross-uppayment to make them whole with respect to any excise taxes imposed by Section 4999 of the Internal Revenue Code. With respect to the preceding sentence, by way of example, if there was a change of control event that applied on September 30, 2006, and assuming that the excise tax were applicable to the transaction, then the additional payments to Messrs. Isenberg and Petrello for thegross-upwould be up to approximately $89 million and $48 million, respectively.
 
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.
 
New Joint Venture
 
On September 22, 2006, we entered into an agreement with First Reserve Corporation to form a new joint venture, NFR Energy LLC, to invest in oil and gas exploitation opportunities worldwide. First Reserve Corporation is a private equity firm specializing in the energy industry. Each party initially will hold an equal interest in the new entity and has committed to fund its proportionate share of $1.0 billion in equity. NFR Energy LLC will pursue development and exploration projects with both existing customers of ours and with other operators in a variety of forms including operated and non-operated working interests, joint ventures, farm-outs and acquisitions. NFR Energy LLC has not commenced operations and has not received funding as of September 30, 2006 by either party.
 
Contingencies
 
Income Tax Contingencies
 
We are subject to income taxes in both the United States and numerous foreign 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 that which is reflected in historical income tax provisions and accruals. Based on the results of an audit or litigation, a material effect on our financial position, income tax provision, net income, or cash flows in the period or periods for which that determination is made could result.
 
It is possible that future changes to tax laws (including tax treaties) could have an impact on our ability to realize the tax savings recorded to date as well as future tax savings as a result of our corporate reorganization, depending on any responsive action taken by us.
 
On May 31, 2006, Nabors International Finance Inc. (“NIFI”), a wholly-owned U.S. subsidiary of Nabors, received from the U.S. Internal Revenue Service (the “IRS”) two Notices of Proposed Adjustment (“NOPA”) in connection with an audit of NIFI for tax years 2002 and 2003. One NOPA proposes to deny a deduction of


17


Table of Contents

 
NABORS INDUSTRIES LTD. AND SUBSIDIARIES
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

$85.1 million in interest expense in our 2002 tax year relating to intercompany indebtedness incurred in connection with our inversion transaction in June 2002 whereby we were reorganized as a Bermuda company. The second NOPA proposes to deny a deduction of $207.6 million in the same item of interest expense in our 2003 tax year. On August 9, 2006, NIFI received a Revenue Agent Report, asserting the adjustments relating to the two NOPAs referred to above. On September 18, 2006, NIFI filed a protest with the IRS related to the two adjustments and we intend to contest the IRS position vigorously. We previously had obtained advice from our tax advisors that the deduction of such amounts was appropriate and more recently that the position of the IRS lacks merit. In 2003 the Company paid off approximately one-half of the intercompany indebtedness incurred in connection with the inversion. We currently have not booked any reserves for such proposed adjustments.
 
On September 14, 2006, Nabors Drilling International Ltd. (NDIL), a wholly-owned Bermuda subsidiary of Nabors, received a Notice of Assessment (the “Notice”) from the Mexican Servicio de Administracion Tributaria (the “SAT”) in connection with the audit of NDIL’s Mexican branch for tax year 2003. The Notice proposes to deny a depreciation expense deduction that relates to drilling rigs operating in Mexico in 2003, as well as a deduction for payments made to an affiliated company for the provision of labor services in Mexico. The amount assessed by the SAT is approximately $19.8 million (including interest and penalties). Nabors and its tax advisors previously concluded that the deduction of said amounts was appropriate and more recently that the position of the SAT lacks merit. Nabors has not booked any reserves for the adjustments proposed by the SAT. NDIL’s Mexican branch took similar deductions for depreciation and labor expenses in 2004, 2005 and 2006. It is likely that the SAT will propose the disallowance of these deductions upon audit of NDIL’s Mexican branch’s 2004, 2005 and 2006 tax years.
 
Self-Insurance Accruals
 
We are self-insured for certain losses relating to workers’ compensation, employers’ liability, general liability, automobile liability and property damage. Effective April 1, 2006, with our insurance renewal, certain changes have been made to our insurance coverage increasing our self-insured retentions. Our domestic workers’ compensation program continues to be subject to a $1.0 million per occurrence deductible. Employers’ liability and Jones Act cases are subject to a $2.0 million deductible. Automobile liability continues at a $.5 million deductible. We are assuming an additional $3.0 million corridor deductible for domestic workers’ compensation claims. General liability claims continue to be subject to a $5.0 million deductible. However, as a result of insurance market conditions following hurricanes Katrina and Rita, we are now subject to higher deductibles for removal of wreckage and debris and collision liability claims depending on the insured value of the individual rigs.
 
In addition, we are subject to a $1.0 million deductible for all land rigs except for those located in Alaska, and a $5.0 million deductible for all our Alaska and offshore rigs with the exception of the Pool Arabia rig, which is subject to a $2.5 million deductible. This applies to all kinds of risks of physical damage except for named windstorms in the U.S. Gulf of Mexico. The deductible for named windstorms in the U.S. Gulf of Mexico is $25.0 million per occurrence. Also, the maximum coverage for named windstorms in the U.S. Gulf of Mexico is $50.0 million in this policy year.
 
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 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.
 
During the quarter ended June 30, 2006, we settled a lawsuit involving wage and hour claims relating primarily to meal periods and travel time of current and former rig-based employees in our California well-servicing business. Those claims were heard by an arbitrator during the fourth quarter of 2005. On February 6, 2006, we received an interim award against us in the amount of $25.6 million (plus attorney’s fees and costs), which was accrued for in our consolidated statements of income for the year ended December 31, 2005. As a result of subsequent proceedings and the settlement, the final award was $24.3 million, which was paid during May 2006.
 
Additionally, on December 22, 2005, we received a grand jury subpoena from the United States Attorney’s Office in Anchorage, Alaska, seeking documents and information relating to an alleged spill, discharge, overflow or cleanup of drilling mud or sludge involving one of our rigs during March 2003. We are cooperating with the authorities in this matter.
 
Guarantees
 
We enter into various agreements and obligations providing 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 a minor acquisition completed during the first quarter of 2005 and in conjunction with the acquisition of Pragma Drilling Equipment Ltd., completed in May of 2006, which are both based on future operating results of those businesses. In addition, we have provided indemnifications to certain third parties which serve as guarantees. These guarantees include indemnification provided by Nabors to our stock 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 amount of financial and performance guarantees issued by Nabors:

(1) Diluted earnings per share for the three and nine months ended September 30, 2006 do not include any incremental shares issuable upon the exchange of the $2.75 billion 0.94% senior exchangeable notes. 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 are required to pay cash up to the principal amount of the notes exchanged. We would only issue an incremental number of shares upon exchange of these notes, and such shares are only included in the calculation of the weighted-average number of shares outstanding in our diluted earnings per share calculation, when the price of our shares exceeds $45.83 on the last trading day of the quarter, which did not occur during the three and nine months ended September 30, 2006. The $2.75 billion notes were issued during the quarter ended June 30, 2006 and had no effect on prior period’s earnings per share calculation.
 
(2) Diluted earnings per share for the three and nine months ended September 30, 2006 excludes approximately 1.2 million potentially dilutive shares initially issuable upon the conversion of the $82 million zero coupon

convertible senior debentures. Diluted earnings per share for the three and nine months ended September 30, 2005 excludes approximately 17.0 million potentially dilutive shares initially issuable upon the conversion of these debentures. Such shares did not impact our calculation of dilutive earnings per share for those quarters, as we are required to pay cash up to the principal amount of any debentures converted. We would only issue an incremental number of shares upon conversion of these debentures, and such shares would only be included in the calculation of the weighted-average number of shares outstanding in our diluted earnings per share calculation if the price of our shares exceeded approximately $49.
 
(3) Diluted earnings per share for the three months ended September 30, 2006 and 2005 and the nine months ended September 30, 2005 do not include any incremental shares issuable upon the exchange of the $700 million zero coupon senior exchangeable notes. 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 are required to pay cash up to the principal amount of the notes exchanged. We would only issue an incremental number of shares upon exchange of these notes, and such shares are only included in the calculation of the weighted-average number of shares outstanding in our diluted earnings per share calculation, when the price of our shares exceeds $35.05 on the last trading day of the quarter. This was the case for the quarter ended March 31, 2006 and is therefore included in the weighted-average number of shares outstanding in our diluted earnings per share calculation for the nine months ended September 30, 2006.
 
(4) Includes the following weighted-average number of common shares of Nabors and weighted-average number of exchangeable shares of Nabors Exchangeco (Canada) Inc., an indirectly wholly-owned Canadian subsidiary of Nabors, respectively: 277.4 million and .2 million shares for the three months ended September 30, 2006; 314.0 million and .4 million shares for the three months ended September 30, 2005; 294.8 million and .2 million shares for the nine months ended September 30, 2006; and 310.8 million and .4 million shares for the nine months ended September 30, 2005. The exchangeable shares of Nabors Exchangeco are exchangeable for Nabors common shares on aone-for-onebasis, and have essentially identical rights as Nabors Industries Ltd. common shares, including but not limited to voting rights and the right to receive dividends, if any.
 
For all periods presented, the computation of diluted earnings per share excludes outstanding stock options and warrants with exercise prices greater than the average market price of Nabors’ common shares, because the inclusion of such options and warrants would be anti-dilutive. The number of options and warrants that were excluded from diluted earnings per share that would potentially dilute earnings per share in the future were 4,327,513 and 2,443,254 shares during the three and nine months ended September 30, 2006 and 2,250 and 1,014,422 shares during the three and nine months ended September 30, 2005. 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 will be included in our diluted earnings per share computation using the treasury stock method of accounting. Restricted stock will similarly be included in our diluted earnings per share computation using the treasury stock method of accounting in any period where the amount of restricted stock exceeds the number of shares assumed repurchased in those periods based upon future unearned compensation.

(1) These segments include our drilling, workover and well-servicing operations, on land and offshore.
 
(2) Includes Earnings (losses), net from unconsolidated affiliates, accounted for by the equity method, of $1.1 million and $(1.1) million for the three months ended September 30, 2006 and 2005, respectively, and $5.9 million and $.7 million for the nine months ended September 30, 2006 and 2005, respectively.
 
(3) Represents our oil and gas exploration, development and production operations.
 
(4) Includes our marine transportation and supply services, 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 by the equity method, of $4.6 million and $1.2 million for the three months ended September 30, 2006 and 2005, respectively, and $13.6 million and $6.6 million for the nine months ended September 30, 2006 and 2005, respectively.
 
(6) Represents the elimination of inter-segment transactions.
 
(7) Adjusted income (loss) derived from operating activities is computed by: subtracting direct costs, general and administrative expenses, and depreciation and amortization, and depletion expense from Operating revenues and then adding Earnings from unconsolidated affiliates. Such amounts should not be used as a substitute to 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 (loss) derived from operating activities, because it believes that this financial measure is an accurate reflection of the ongoing profitability of our company. A reconciliation of this non-GAAP measure to income before income taxes, which is a GAAP measure, is provided within the table above.
 
(8) Represents the elimination of inter-segment transactions and unallocated corporate expenses and assets.
 
(9) Includes $41.8 million and $35.3 million of investments in unconsolidated affiliates accounted for by the equity method as of September 30, 2006 and December 31, 2005, respectively.
 
(10) Includes $49.4 million and $35.9 million of investments in unconsolidated affiliates accounted for by the equity method as of September 30, 2006 and December 31, 2005, 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 as of September 30, 2006, and the related consolidated statements of income for each of the three-month and nine-month periods ended September 30, 2006 and 2005, and the consolidated statements of cash flows and of changes in shareholders’ equity for the nine-month periods ended September 30, 2006 and 2005. This interim financial information is the responsibility of the Company’s management.
 
We conducted our review in accordance with 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, 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, 2005, and the related consolidated statements of income, of cash flows, and of changes in shareholders’ equity for the year then ended, management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005 and the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005; and in our report dated March 16, 2006, we expressed unqualified opinions thereon. The consolidated financial statements and management’s assessment of the effectiveness of internal control over financial reporting referred to above are not presented herein. In our opinion, the information set forth in the accompanying consolidated balance sheet information as of December 31, 2005, 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 of 1933 and Section 21E of the 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.
 
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 Annual Report onForm 10-Kfor the year ended December 31, 2005 filed with the Securities and Exchange Commission under Part 1, Item 1A, “Risk Factors.”
 
Unless the context requires otherwise, references in this Quarterly Report onForm 10-Qto the “Company,” “we,” “us,” “our,” or “Nabors” means Nabors Industries Ltd. and, where the context requires, includes our subsidiaries.
 
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 to our consolidated financial statements.
 
Nabors is the largest land drilling contractor in the world. We conduct oil, gas and geothermal land drilling operations in the U.S. Lower 48 states, Alaska, Canada, South and Central America, the Middle East, the Far East and Africa. Nabors also is one of the largest land well-servicing and workover contractors in the United States and Canada and is a leading provider of offshore platform workover and drilling rigs in the United States and multiple international markets. To further supplement and complement our primary business, we offer a wide range of ancillary well-site services, including engineering, transportation, construction, maintenance, well logging, directional drilling, rig instrumentation, data collection and other support services, in selected domestic and international markets. During the first quarter of 2006, we began to offer logistics services for onshore drilling and well-servicing operations in Canada using helicopter and fixed-winged aircraft purchased from Airborne Energy

Solutions Ltd. on January 3, 2006 (see Note 4 to our accompanying consolidated financial statements). We have also made selective investments in oil and gas exploration, development and production activities.
 
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 a category labeled Oil and Gas for segment reporting purposes. Our operating segments engaged in marine transportation and supply services, drilling technology and top drive manufacturing, directional drilling, rig instrumentation and software, and construction and logistics operations are aggregated in a category labeled Other Operating Segments for segment reporting purposes.
 
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 driver of our U.S. Lower 48 Land Drilling, Canadian and U.S. Offshore (Gulf of Mexico) operations, while oil prices are the primary driver of our Alaskan, International and U.S. Land Well-servicing operations. The Henry Hub natural gas spot price (per Bloomberg) averaged $8.05 per million cubic feet (mcf) during the period from October 1, 2005 through September 30, 2006, up from $7.41 per mcf average during the period from October 1, 2004 through September 30, 2005. West Texas intermediate spot oil prices (per Bloomberg) averaged $66.11 per barrel during the period from October 1, 2005 through September 30, 2006, up from a $53.69 per barrel average during the period from October 1, 2004 through September 30, 2005.
 
Operating revenues and Earnings from unconsolidated affiliates for the three months ended September 30, 2006 totaled $1.3 billion, representing an increase of $356.8 million, or 40% as compared to the three months ended September 30, 2005 and $3.5 billion for the nine months ended September 30, 2006, representing an increase of $1.1 billion, or 45% as compared to the nine months ended September 30, 2005. Adjusted income derived from operating activities and net income for the three months ended September 30, 2006 totaled $380.8 million and $292.8 million, ($1.02 per diluted share), respectively, representing increases of 57% and 64%, respectively, compared to the three months ended September 30, 2005. Adjusted income derived from operating activities and net income for the nine months ended September 30, 2006 totaled $1.1 billion and $782.9 million ($2.57 per diluted share), respectively, representing increases of 87% and 79% respectively, compared to the nine months ended September 30, 2005.
 
The increase in our operating results during the three and nine months ended September 30, 2006 resulted from higher revenues realized by essentially all of our operating segments. Revenues increased as a result of higher average dayrates and activity levels during the three and nine months ended September 30, 2006 compared to the prior year periods. This increase in average dayrates and activity reflects an increase in demand for our services in these markets during the three and nine months ended September 30, 2006, which resulted from strong capital spending by our customers as supply challenges persist and cash flows remain adequate and confidence in the long-term outlook of higher price levels for natural gas and oil regardless of short-term price volatility. These increases were accomplished in light of delivery slippage on new rigs for both drilling and workover rigs, and a larger than expected impact from our customers’ deferral of work in the Gulf of Mexico during the hurricane season.
 
Our operating results for 2006 are expected to increase from levels realized during 2005 as a result of:
 
  • Our current expectation of the continuation of historically high commodity prices during 2006 and the related impact on drilling and well-servicing activity, dayrates for drilling services and hourly well-servicing rates, and
 
  • Our current expectation of the impact on our overall level of drilling and well-servicing activity resulting from new or substantially new rigs to be added as part of our expanded capital program and planned reactivations of and enhancements to existing rigs.
 
The expansion of our rig fleet through our expanded capital program is expected to most significantly impact the results of our U.S. Lower 48 Land Drilling, U.S. Land Well-servicing, Canadian and International operations. For our existing rigs, we expect the largest increase in drilling activity and dayrates to exist in our U.S. Lower

Table of Contents

48 Land Drilling operations as a result of strong demand for drilling services in that market driven by the sustained level of higher natural gas prices. We also expect strong demand for our drilling and well-servicing services across a number of our other markets, resulting from higher commodity prices, to improve our results of operations from existing rigs for our U.S. Land Well-servicing, Canadian, International and U.S. Offshore operations. Canadian drilling activity is subject to substantial levels of seasonality, as activity levels typically peak in the first quarter, decline substantially in the second quarter, and then generally increase over the last half of the year. We expect that the improvement in our International operations will also be driven by multiple rig contract re-pricings, which should begin to impact our results in the second half of 2006. We expect that the improvement in our U.S. Offshore operations will also be driven by a continuing improvement in the utilization of and pricing for our workoverjack-uprigs. We expect results from our operations in Alaska to be substantially unchanged during 2006 when compared to 2005, as the improvement in demand for drilling services as a result of increases in commodity prices have just started to be demonstrated in this market during the latter half of 2006.
 
During the second quarter of 2006, our wholly-owned subsidiary, Nabors Delaware, placed $2.75 billion in five-year exchangeable notes with a 0.94% coupon interest rate and an original exchange premium of 30%. In order to offset the potential dilution to our shares, Nabors Delaware entered into a series of hedge transactions which effectively increased the exchange premium to 55%. In the hedge transactions, Nabors Delaware purchased call options which will cover the net shares of our common shares that would be deliverable to the note-holders upon exchange of the notes. In order to partially offset the cost of the purchased call options (but which also limits the anti-dilutive effect of the call options), we sold warrants to acquire approximately 60.0 million of our common shares at a strike price of $54.64. The net cost of these hedge transactions was approximately $162.4 million. These costs were accounted for as a reduction to shareholders’ equity. A portion of the proceeds from the notes were also used to repurchase approximately 28.5 million shares of our common stock for approximately $1.0 billion, which further reduced shareholders’ equity. These decreases to equity as a result of these transactions were partially offset by a $215.9 million increase to equity related to a deferred tax asset representing the tax benefits of the cost of the purchased call option, which was also accounted for through shareholders’ equity. We expect these transactions to be accretive to our results by roughly $.26 per share in 2006 and $.56 per share in 2007. After the consummation of this transaction, we had approximately $2.0 billion in cash and investments, which we believe puts us in an excellent position to capitalize on future opportunities.

The increase in operating revenues and earnings from unconsolidated affiliates during the three and nine months ended September 30, 2006 is primarily due to increases in average dayrates and drilling activity levels as compared to prior year periods. The decrease in overall operating results during the three and nine months ended September 30, 2006 as compared to prior year periods relate to increased labor and repairs and maintenance costs.

The increase in operating results during the three months ended September 30, 2006 over the prior year period primarily resulted from increases in average dayrates and hourly rates, as well as foreign exchange increases due to the strengthening of the Canadian dollar against the U.S. dollar. These increases were partially offset by a decline in drilling activity due to lower demand stemming from lower natural gas prices during the three months ended September 30, 2006. The increase in operating results during the nine months ended September 30, 2006 primarily resulted from an overall increase in drilling and well-servicing activity and an increase in average dayrates and hourly rates for drilling and well-servicing operations compared to the prior year periods. These increases were driven by increased natural gas prices, which resulted in improved demand for our services in this market. Further increases in operating results in the nine month period were due to foreign exchange increases as a result of the Canadian dollar strengthening against the U.S. dollar during these periods.

The decrease in operating results during the three months ended September 30, 2006, as compared to the prior year period, related primarily from the expected decline in production from our investments with El Paso Corporation and higher direct costs. The higher direct costs increased due to geological and geophysical expenses incurred in Colombia, increased expenses due to additional producing wells during 2006 as well as non-recurring workover expenses incurred on one of our wells. Operating results during the nine months ended September 30, 2006 increased only slightly as compared to the prior year period. Operating results during the nine months ended September 30, 2006 were positively impacted from the sale of certain leasehold interests. Such sale resulted in additional operating revenue totaling $20.7 million during the nine months ended September 30, 2006 and was partially offset by lower production resulting from the expected decline in production from our investments with El Paso Corporation. During the nine months ended September 30, 2006, we incurred higher seismic costs and work-over expenses discussed above as compared to prior period and also recorded an impairment of oil and gas properties totaling approximately $7.5 million that was recorded as depletion expense. This impairment resulted from lower than expected performance of certain asset groups.

The overall increase in our operating results during the three and nine months ended September 30, 2006 primarily resulted from (i) increased sales of top drives driven by the strengthening of the oil and gas drilling market and increased equipment sales associated with the acquisition of Pragma Drilling Equipment Ltd. in May 2006, (ii) increased demand for directional drilling, rig instrumentation and data collection services during the nine months ended September 30, 2006, primarily driven by a strong U.S. and Canadian market for directional drilling services as the number of horizontal and directional wells drilled increased substantially. Adjusted income derived from operating activities during the three months ended September 30, 2006 decreased as compared to the prior year period for directional drilling primarily due to a decline in Western Canada operations due to declining commodity

General and administrative expenses increased during the three and nine months ended September 30, 2006 primarily as a result of increases in wages and burden for a majority of our operating segments compared to the prior year quarter, which primarily resulted from an increase in the number of employees required to support the increase in activity levels and from higher wages, and increased corporate compensation expense, which primarily resulted from higher bonus accruals and non-cash compensation expenses recorded for stock options and restricted stock grants during the three and nine months ended September 30, 2006 compared to the prior year periods. For the three and nine months ended September 30, 2006, general and administrative expenses, as a percentage of Operating revenues, remained comparable to the prior year periods.

Depreciation and amortization expense.  Depreciation and amortization expense increased during the three months and nine months ended September 30, 2006 compared to the prior year periods as a result of depreciation on capital expenditures made during the last 12 months and increases in average rig years for our U.S. Lower 48 Land Drilling, Canadian land drilling and International operations.
 
Depletion expense.  Depletion expense decreased during the three and nine month periods ended September 30, 2006 compared to the prior year periods due to lower oil and gas production due to the payout of the El Paso Red River program in late 2005. These decreases were partially offset due to increases in depletion expense on non-El Paso properties due to an impairment of $7.5 million. The impairment resulted from lower than expected performance of certain asset groups.

senior exchangeable notes due 2011. This increase was partially offset by interest expense reductions resulting from the redemption of 93% or $769.8 million of our zero coupon convertible senior debentures due 2021 on February 6, 2006. These zero coupon notes accreted at a rate of 2.5% per annum. See further discussion of these transactions in Note 5 to our accompanying consolidated financial statements.

Investment income increased during the three and nine months ended September 30, 2006 compared to the prior year periods primarily as a result of higher interest income earned on investments in cash and marketable securities due to rising interest rates and a higher average investment balance related to the proceeds from the issuance of the $2.75 billion 0.94% senior exchangeable notes due 2011 received in May 2006. In addition, earnings on our non-marketable securities increased during the three months ended September 30, 2006 as compared to the prior year period. The increase was partially reduced in the three and nine month periods ended September 30, 2006 compared to the prior year periods by reduced gains realized from the sale of equity securities.

The amount of losses (gains) on sales of long-lived assets, impairment charges and other (income) expense, net for the three and nine months ended September 30, 2006 include losses on long-term assets of approximately $1.2 million and $9.3 million, respectively. The amount of losses (gains) on sales of long-lived assets, impairment charges and other (income) expense, net for the three months ended September 30, 2005 include losses on long-term assets of approximately $7.6 million, which primarily consists of impairment charges recorded as a result of damage sustained in Hurricanes Katrina and Rita of approximately $2.2 million and $5.4 million, respectively. Losses (gains) on sales of long-lived assets, impairment charges and other (income) expense, during the nine months ended September 30, 2005, include losses on long-lived assets of approximately $10.7 million, which primarily consists of impairment charges recorded as a result of Hurricanes Katrina and Rita during the third quarter of 2005 discussed above.

Effective income tax rate
  26.8%  26.2%  0.6%  2%  30.2%  25.1%  5.1%  20%
 
The increase in our effective income tax rate resulted from a higher proportion of our taxable income being generated in the U.S. during the three and nine months ended September 30, 2006 compared to the prior year periods. Income generated in the U.S. is generally taxed at a higher rate than in international jurisdictions in which we operate. Additionally, during the three months ended June 30, 2006, we recorded a $36.2 million current tax expense relating to the redemption of common shares held by a foreign parent of a U.S. based Nabors’ subsidiary. This income tax expense was partially offset by an approximate $20.5 million deferred tax benefit recorded as a result of changes in Canadian laws that incrementally reduce statutory tax rates for both federal and provincial taxes

over the next four years. We expect our effective tax rate during 2006 to be in the 29% — 31% range because we expect a higher proportion of our income to be generated in the U.S.
 
In October 2004 the U.S. Congress passed and the President signed into law the American Jobs Creation Act of 2004. The Act did not impact the corporate reorganization completed by Nabors effective June 24, 2002, that made us a foreign entity. Various bills have been introduced in Congress that could mitigate or eliminate the tax benefits associated with our reorganization as a Bermuda company. Because we cannot predict whether legislation ultimately will be adopted, no assurances can be given that the tax benefits associated with our reorganization ultimately will accrue to the benefit of the Company and its shareholders. It is possible that future changes to tax laws (including tax treaties) could have an impact on our ability to realize the tax savings recorded to date as well as future tax savings as a result of our corporate reorganization, depending on any responsive action taken by Nabors.
 
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 nine months ended September 30, 2006 and 2005.
 
Operating Activities.  Net cash provided by operating activities totaled $1.0 billion during the nine months ended September 30, 2006, compared to net cash provided by operating activities of $665.4 million during the prior year period. During the nine months ended September 30, 2006 and 2005, net income was increased for non-cash items such as depreciation and amortization, and depletion, and was reduced for changes in our working capital (primarily accounts receivable) and other balance sheet accounts.
 
Investing Activities.  Net cash used for investing activities totaled $1.7 billion during the nine months ended September 30, 2006, compared to net cash used for investing activities of $590.4 million during the prior year period. During the nine months ended September 30, 2006 cash was used for capital expenditures, which was partially offset by sales, net of purchases, of investments. During the nine months ended September 30, 2005 cash was used for capital expenditure.
 
Financing Activities.  Net cash provided by financing activities totaled $426.9 million during the nine months ended September 30, 2006 compared to net cash provided by financing activities of $109.6 million during the prior year period. During the nine months ended September 30, 2006, cash was provided by approximately $2.72 billion in net proceeds from the issuance of the $2.75 billion 0.94% senior exchangeable notes due 2011 by Nabors Delaware and by approximately $421.2 million from the sale of the warrants. During this same period, cash was used for the purchase of call options in the amount of $583.6 million, the redemption of 93% of our zero coupon senior convertible debentures due 2021 for a total redemption price of $769.8 million and for repurchases of our common shares in the open market for $1.4 billion. During the nine months ended September 30, 2005, cash was provided by our receipt of proceeds totaling $186.7 million from the exercise of options to acquire our common shares by our employees and was used for the repurchase of our common shares in the open market totaling $80.6 million.
 
Future Cash Requirements
 
As of September 30, 2006, we had long-term debt, including current maturities, of $4.0 billion and cash and cash equivalents and investments of $1.8 billion.
 
Nabors Delaware’s $2.75 billion 0.94% senior exchangeable notes due 2011 provide that upon an exchange of these notes, it will be required to pay holders of the notes, in lieu of common shares, cash up to the principal amount of the notes and our common shares for any amount exceeding the principal amount of the notes required to be paid pursuant to the terms of the note indentures. The $700 million zero coupon senior exchangeable notes provide that upon an exchange of these notes, we will be required to pay holders of the notes, in lieu of common shares, cash up

Table of Contents

to the principal amount of the notes and, at our option, consideration in the form of either cash or our common shares for any amount above the principal amount of the notes required to be paid pursuant to the terms of the note indentures. The $2.75 billion 0.94% senior exchangeable 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; or upon the occurrence of specified corporate transactions set forth in the indenture. The $700 million zero coupon senior exchangeable notes cannot be exchanged until the price for our shares exceeds $42.06 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 with respect to all calendar quarters beginning on or after July 1, 2008, $38.56 of the applicable exchange price per share of Nabors’ common shares on such last trading day or subject to certain exceptions, during the five business day period after 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; or if Nabors Delaware calls the notes for redemption; or upon the occurrence of specified corporate transactions described in the note indenture.
 
As of September 30, 2006, we had outstanding purchase commitments of approximately $731.0 million, primarily for rig-related enhancing, construction and sustaining capital expenditures. Total capital expenditures over the next twelve months, including these outstanding purchase commitments, are currently expected to be at least $2.2 billion, including currently planned rig-related enhancing, 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 twelve months represent a number of capital programs that are currently underway or planned. These programs will result in an expansion in the number of drilling and well-servicing rigs that we own and operate and will consist primarily of land drilling and well-servicing rigs. The increase in capital expenditures is expected across a majority of our operating segments, most significantly within our U.S. Lower 48 Land Drilling, U.S. Land Well-servicing, Canadian, and International operations.
 
On September 22, 2006, we entered into an agreement with First Reserve Corporation to form a new joint venture, NFR Energy LLC, to invest in oil and gas exploitation opportunities worldwide. First Reserve Corporation is a private equity firm specializing in the energy industry. Each party initially will hold an equal interest in the new entity and has committed to fund its proportionate share of $1.0 billion in equity. NFR Energy LLC will pursue development and exploration projects with both existing customers of ours and with other operators in a variety of forms including operated and non-operated working interests, joint ventures, farm-outs and acquisitions. NFR Energy LLC has not commenced operations and has not received funding as of September 30, 2006 by either party.
 
Our 2005 Annual Report onForm 10-Kincludes our contractual cash obligations table as of December 31, 2005. As a result of the increase in our outstanding purchase commitments discussed above, and as a result of the issuance of Nabors Delaware’s $2.75 billion 0.94% senior exchangeable notes due 2011 (see Note 5), we are presenting the following table in this Report which summarizes our remaining contractual cash obligations related to purchase commitments as of September 30, 2006:

(3) Purchase obligations include agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable pricing provisions; and the approximate timing of the transaction.
 
No other significant changes have occurred to the contractual cash obligations information disclosed in our 2005 Annual Report onForm 10-K.
 
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 issuance of debt or Nabors’ shares. Such capital expenditures and acquisitions will depend on our view of market conditions and other factors.
 
Our Board of Directors in July 2006 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. This program supersedes and cancels our previous share repurchase program. Through September 30, 2006, approximately $90.8 million of our common shares had been repurchased under this program. As of September 30, 2006, we had $409.2 million of shares that still may be purchased under the July 2006 share repurchase program.
 
See Note 8 to our accompanying consolidated financial statements for discussion of commitments and contingencies that could have a potential impact on our financial position, results of operations or cash flows in future periods.
 
Financial Condition and Sources of Liquidity
 
Our primary sources of liquidity are cash and cash equivalents, marketable and non-marketable securities and cash generated from operations. As of September 30, 2006, we had cash and cash equivalents and investments of $1.8 billion (including $491.4 million of long-term investments) and working capital of $2.0 billion. This compares to cash and cash equivalents and investments of $1.6 billion (including $222.8 million of long-term investments) and working capital of $1.3 billion as of December 31, 2005.
 
The increase in cash and cash equivalents and investments in marketable securities relates primarily to the proceeds from the issuance of the $2.75 billion 0.94% senior exchangeable notes due 2011 during the second quarter, which resulted in net proceeds of $2.72 billion and the proceeds of approximately $421.2 million from the sale of the warrants, partially offset by the purchase of call options on our common shares for approximately $583.6 million, the redemption of 93% of our $1.2 billion zero coupon senior convertible debentures due 2021 during the first quarter of 2006 for a total redemption price of $769.8 million (leaving approximately $82 million) and the $1.4 billion repurchase of our common shares. The increase in working capital relates primarily to the increase in cash and cash equivalents and short-term marketable securities explained above.
 
Our gross funded debt to capital ratio was 0.51:1 as of September 30, 2006 and 0.32:1 as of December 31, 2005. Our net funded debt to capital ratio was 0.37:1 as of September 30, 2006 and 0.08:1 as of December 31, 2005. The gross funded debt to capital ratio is calculated by dividing funded debt by funded debt plus deferred tax liabilities net of deferred tax assets plus capital. Funded debt is defined as the sum of (1) short-term borrowings, (2) current portion of long-term debt and (3) long-term debt. Capital is defined as shareholders’ equity. The net funded debt to capital ratio nets cash and cash equivalents and marketable and non-marketable securities against funded debt. This ratio is calculated by dividing net funded debt by net funded debt plus deferred tax liabilities net of deferred tax assets plus capital. Both of these ratios are a method for calculating the amount of leverage a company has in relation to its capital. Non-marketable securities consist of investments in overseas funds investing primarily in a variety of public and private U.S. andnon-U.S. securities(including asset-backed securities and mortgage-backed securities, global structured asset securitizations, whole loan mortgages, and participations in whole loans and whole loan mortgages). These investments are classified as non-marketable, because they do not have published fair values. Our interest coverage ratio was 38.3:1 as of September 30, 2006, compared to 26.1:1 as of December 31,


47


Table of Contents

2005. The interest coverage ratio is computed by calculating the sum of income before income taxes, interest expense, depreciation and amortization, and depletion expense less investment income and then dividing by interest expense. This ratio is a method for calculating the amount of operating cash flows available to cover interest expense.
 
We have three letter of credit facilities with various banks as of September 30, 2006. Availability and borrowings under our credit facilities as of September 30, 2006 are as follows:
 
     
(In thousands) 
 
Credit available
 $147,542 
Letters of credit outstanding

We have a shelf registration statement on file with the Securities and Exchange Commission to allow us to offer, from time to time, up to $700 million in debt securities, guarantees of debt securities, preferred shares, depository shares, common shares, share purchase contracts, share purchase units and warrants. We currently have not issued any securities registered under this registration statement.
 
Our current cash and cash equivalents, investments in marketable and non-marketable securities and projected cash flows generated from current operations are expected to more than adequately finance our purchase commitments, our debt service requirements, and all other expected cash requirements for the next 12 months. However, as discussed under Future Cash Requirements above, the $2.75 billion, 0.94% senior exchangeable notes and $700 million zero coupon senior exchangeable notes can be exchanged when the price for our shares exceeds $59.57 and $42.06, respectively, for the required period of time, resulting in our payment of the principal amount of the notes, or $2.75 billion and $700 million, respectively, in cash.
 
On October 26, 2006, the market price for our shares closed at $31.82. If the market price threshold of $59.57 or $42.06 was exceeded and the notes were exchanged, 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. Nabors’ management believes that 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 on the open market, however there can be no assurance that the holders would not exchange the notes. Further, management believes that we have the ability to access capital markets or otherwise obtain financing in order to satisfy any payment obligations that might arise upon exchange of these notes and that any cash payment due of this magnitude, in addition to our other cash obligations, will not ultimately have a material adverse impact on our liquidity or financial position. Our ability to access capital markets or to otherwise obtain sufficient financing is enhanced by our senior unsecured debt ratings as provided by Moody’s Investor Service and Fitch Ratings, which are currently “A3” and “A−”, respectively, and our historical ability to access those markets as needed.

Other Matters
 
Recent Accounting Pronouncements
 
In June 2006 the FASB issued Interpretation No. 48 (FIN 48), “Accounting for Uncertainty in Income Taxes,” which prescribes a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. Under FIN 48, the financial statements will reflect expected future tax consequences of such positions presuming the taxing authorities’ full knowledge of the position and all relevant facts, but without considering time values. FIN 48 is likely to cause greater volatility in income statements as more items are recognized discretely within income tax expense. Application of FIN 48 is required in financial statements effective for periods beginning after December 15, 2006. FIN 48 revises disclosure requirements and will require an annual tabular roll-forward of unrecognized tax benefits. We expect to adopt FIN 48 beginning January 1, 2007. We are currently evaluating the impact


48


Table of Contents

that this interpretation may have on our consolidated financial statements. Any adjustment required as a result of the adoption of FIN 48 will be recorded to retained earnings.
 
In September 2006 the FASB issued SFAS No. 157, “Fair Value Measurements.” This statement establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The provisions of SFAS 157 should be applied prospectively as of the beginning of the fiscal year in which SFAS 157 is initially applied, except in limited circumstances. We expect to adopt SFAS 157 beginning January 1, 2008. We are currently evaluating the impact that this interpretation may have on our consolidated financial statements.
 
In September 2006 the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans an amendment of FASB Nos. 87, 88, 106 and 132(R).” This statement requires companies to recognize a net liability or asset to report the funded status of their defined benefit pension and other postretirement benefit plans in its statement of financial position and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. SFAS 158 is required to be applied in financial statements effected for periods ending after December 15, 2006. We will adopt SFAS 158 as of December 31, 2006. We do not believe that the adoption of SFAS 158 will have a material impact on our financial position, results of operations or cash flows.
 
The Company has several stock-based employee compensation plans, which are more fully described in Note 9 in the Company’s 2005 Annual Report onForm 10-K.Prior to January 1, 2006, we accounted for awards granted under those plans following the recognition and measurement principles of Accounting Principles Bulletin (APB) Opinion No. 25, “Accounting for Stock Issued to Employees,” (APB 25) and related interpretations. Under APB 25, no compensation expense was reflected in net income for the Company’s stock options, as all options granted under those plans had an exercise price equal to the market value of the underlying common shares on the date of grant. The pro forma effects on income for stock options were instead disclosed in a footnote to the financial statements. Compensation expense was recorded in the income statement for restricted stock grants over the vesting period of the award.
 
Effective January 1, 2006, we adopted the fair value recognition provisions of FASB Statement of Financial Accounting Standard No. 123(R), “Share-Based Payments,”(SFAS 123-R),using the modified prospective application method. Under this transition method, the Company will record compensation expense for all stock option awards granted after the date of adoption and for the unvested portion of previously granted stock option awards that remain outstanding at the date of adoption. The amount of compensation cost recognized was based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123. Results for prior periods have not been restated.
 
As a result of adoptingSFAS 123-Ron January 1, 2006, Nabors’ income before income taxes and net income for the three months ended September 30, 2006 was $4.2 million, and $3.3 million lower, respectively, and $14.0 million and $10.8 million lower for the nine months ended September 30, 2006, respectively, than if we had continued to account for share-based compensation under APB 25. Basic and diluted earnings per share for the three months ended September 30, 2006 would have been $1.07 and $1.03, respectively, and $2.69 and $2.60, respectively, for the nine months ended September 30, 2006, if the Company had continued to account for share-based compensation under APB 25, compared to reported basic and diluted earnings per share of $1.05 and $1.02, respectively, for the three months ended September 30, 2006 and $2.65 and $2.57, respectively, for the nine months ended September 30, 2006. See the disclosures required upon adoption ofSFAS 123-Rin Note 3 to our accompanying consolidated financial statements.
 
Critical Accounting Estimates
 
We disclosed our critical accounting estimates in our 2005 Annual Report onForm 10-K.No significant changes have occurred to those policies.

Self-Insurance Accruals
 
We are self-insured for certain losses relating to workers’ compensation, employers’ liability, general liability, automobile liability and property damage. Effective April 1, 2006, with our insurance renewal, certain changes have been made to our insurance coverage increasing our self-insured retentions. Our domestic workers’ compensation program continues to be subject to a $1.0 million per occurrence deductible. Employers’ liability and Jones Act cases are subject to a $2.0 million deductible. Automobile liability continues at a $.5 million deductible. We are assuming an additional $3.0 million corridor deductible for domestic workers’ compensation claims. General liability claims continue to be subject to a $5.0 million deductible. However, as a result of insurance market conditions following hurricanes Katrina and Rita, we are now subject to higher deductibles for removal of wreckage and debris and collision liability claims depending on the insured value of the individual rigs.
 
In addition, we are subject to a $1.0 million deductible for all land rigs except for those located in Alaska, and a $5.0 million deductible for all our Alaska and offshore rigs with the exception of the Pool Arabia rig, which is subject to a $2.5 million deductible. This applies to all kinds of risks of physical damage except for named windstorms in the U.S. Gulf of Mexico. The deductible for named windstorms in the U.S. Gulf of Mexico is $25.0 million per occurrence. Also, the maximum coverage for named windstorms in the U.S. Gulf of Mexico is $50.0 million in this policy year.
 
Income Tax Contingencies
 
We are subject to income taxes in both the United States and numerous foreign 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 that which is reflected in historical income tax provisions and accruals. Based on the results of an audit or litigation, a material effect on our financial position, income tax provision, net income, or cash flows in the period or periods for which that determination is made could result.
 
It is possible that future changes to tax laws (including tax treaties) could have an impact on our ability to realize the tax savings recorded to date as well as future tax savings as a result of our corporate reorganization, depending on any responsive action taken by us.
 
On May 31, 2006, NIFI, a wholly-owned subsidiary of Nabors, received from the U.S. Internal Revenue Service (the “IRS”) two Notices of Proposed Adjustment (“NOPA”) in connection with an audit of NIFI for tax years 2002 and 2003. One NOPA proposes to deny a deduction of $85.1 million in interest expense in our 2002 tax year relating to intercompany indebtedness incurred in connection with our inversion transaction in June 2002 whereby we were reorganized as a Bermuda company. The second NOPA proposes to deny a deduction of $207.6 million in the same item of interest expense in our 2003 tax year. On August 9, 2006, NIFI received a Revenue Agent Report, asserting the adjustments relating to the two NOPAs referred to above. On September 18, 2006, NIFI filed a protest with the IRS related to the two adjustments and we intend to contest the IRS position vigorously. We previously had obtained advice from our tax advisors that the deduction of such amounts was appropriate and more recently that the position of the IRS lacks merit. In 2003 the company paid off approximately one-half of the intercompany indebtedness incurred in connection with the inversion. We currently have not booked any reserves for such proposed adjustments.
 
On September 14, 2006, Nabors Drilling International Ltd. (NDIL), a wholly-owned Bermuda subsidiary of Nabors, received a Notice of Assessment (the “Notice”) from the Mexican Servicio de Administracion Tributaria (the “SAT”) in connection with the audit of NDIL’s Mexican branch for tax year 2003. The Notice proposes to deny a depreciation expense deduction that relates to drilling rigs operating in Mexico in 2003, as well as a deduction for payments made to an affiliated company for the provision of labor services in Mexico. The amount assessed by the SAT is approximately $19.8 million (including interest and penalties). Nabors and its tax advisors previously concluded that the deduction of said amounts was appropriate and more recently that the position of the SAT lacks merit. Nabors has not booked any reserves for the adjustments proposed by the SAT. NDIL’s Mexican branch took

Table of Contents

similar deductions for depreciation and labor expenses in 2004, 2005 and 2006. It is likely that the SAT will propose the disallowance of these deductions upon audit of NDIL’s Mexican branch’s 2004, 2005 and 2006 tax years.
 
Off-Balance Sheet Arrangements (Including Guarantees)
 
We are a party to certain 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 in 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 a minor acquisition completed during the first quarter of 2005, which is based on future operating results of that business. In addition, we have provided indemnifications to certain third parties which serve as guarantees. These guarantees include indemnification provided by Nabors to our stock 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.
 
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 due to our operations in international markets as discussed in our 2005 Annual Report onForm 10-K.Material changes in our exposure to market risk from that disclosed in our 2005 Annual Report onForm 10-Kare discussed below.
 
On October 21, 2002, we entered into an interest rate swap transaction with a third-party financial institution to hedge our exposure to changes in the fair value of $200 million of our fixed rate 5.375% senior notes due 2012, which has been designated as a fair value hedge under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended by SFAS 149. Additionally, on October 21, 2002, we purchased a LIBOR range cap and sold a LIBOR floor, in the form of a cashless collar, with the same third-party financial institution with the intention of mitigating and managing our exposure to changes in the three-month U.S. dollar LIBOR rate. This transaction does not qualify for hedge accounting treatment under SFAS 133, as amended by SFAS 149, and any change in the cumulative fair value of this transaction is reflected as a gain or loss in our consolidated statements of income. In June 2004 we unwound $100 million of the $200 million range cap and floor derivative instrument. During the fourth quarter of 2005, we unwound the interest rate swap resulting in a loss of $2.7 million, which has been deferred and will be recognized as an increase to interest expense over the remaining life of our 5.375% senior notes due 2012.
 
The fair value of our range cap and floor transaction recorded as a derivative asset and included in other long-term assets totaled approximately $2.0 million and $1.5 million as of September 30, 2006 and December 31, 2005, respectively. We recordedmark-to-marketgains (losses), included in losses (gains) on sales of long-lived assets, impairment charges and other expense (income), net of approximately $(.8) million and $.8 million during the three and nine months ended September 30, 2006, respectively, andmark-to-marketgains of $.9 million and $.7 million during the three and nine months ended September 30, 2005, respectively, resulting from the change in cumulative fair value of this derivative instrument during those periods.
 
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 Securities and Exchange Commission’s rules and forms. We have investments in certain unconsolidated entities that we do not control or manage. As 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.

Table of Contents

The Company’s management, with the participation of the Company’s Chairman and Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined inRules 13a-15(e)and15d-15(e)under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, the Company’s Chairman and Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures are effective, at the reasonable assurance level, in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act and are effective, at the reasonable assurance level, in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including the Company’s Chairman and Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

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.
 
During the quarter ended June 30, 2006, we settled a lawsuit involving wage and hour claims relating primarily to meal periods and travel time of current and former rig-based employees in our California well-servicing business. Those claims were heard by an arbitrator during the fourth quarter of 2005. On February 6, 2006, we received an interim award against us in the amount of $25.6 million (plus attorneys’ fees and costs), which was accrued for in our consolidated statements of income for the year ended December 31, 2005. As a result of subsequent proceedings and the settlement, the final award was $24.3 million, which was paid during May 2006.
 
Additionally, on December 22, 2005, we received a grand jury subpoena from the United States Attorney’s Office in Anchorage, Alaska, seeking documents and information relating to an alleged spill, discharge, overflow or cleanup of drilling mud or sludge involving one of our rigs during March 2003. We are cooperating with the authorities in this matter.
 
Item 1A.  Risk Factors
 
We have a substantial amount of debt outstanding
 
We had approximately $2.0 billion in debt outstanding as of December 31, 2005 resulting in a gross funded debt to capital ratio of 0.32:1 and a net funded debt to capital ratio of 0.08:1. Both of these ratios are a method for calculating the amount of leverage a company has in relation to its capital. As a result of the completion of the private placement of $2.75 billion 0.94% senior exchangeable notes due 2011 during the second quarter of 2006, and the redemption of 93% of our $1.2 billion zero coupon senior convertible debentures due 2021 during the first quarter of 2006, we have approximately $4.0 billion in debt outstanding, resulting in a gross funded debt to capital

ratio of 0.51:1 and a net funded debt to capital ratio of 0.37:1 at September 30, 2006. As a result of these transactions, we have increased our indebtedness by approximately $2.0 billion, which could adversely affect our senior unsecured debt rating, the ratings of our outstanding indebtedness and the value of our notes.
 
Proposed tax legislation could mitigate or eliminate the benefits of our 2002 reorganization as a Bermuda company
 
Various bills have been introduced in Congress which could mitigate or eliminate the tax benefits associated with our reorganization as a Bermuda company. Because we cannot predict whether legislation ultimately will be adopted, no assurances can be given that the tax benefits associated with our reorganization ultimately will accrue to the benefit of the Company and its shareholders. It is possible that further changes to tax laws (including tax treaties) could have an impact on our ability to realize the tax savings recorded to date as well as future tax savings as a result of our reorganization, depending upon any responsive action we take.
 
There have been no other material changes during the three months ended September 30, 2006 in our “Risk Factors” as discussed in ourForm 10-Kfor the fiscal year ended December 31, 2005.

This program supersedes and cancels our previous share repurchase program. Through September 30, 2006, approximately $90.8 million of our common shares had been repurchased under this program. As of September 30, 2006, we had $409.2 million of shares that still may be purchased under the July 2006 share repurchase program.
