NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
($ Amounts in thousands, except per share amounts)

Unless the context requires otherwise, a reference in this quarterly report to “Bronco,” the “Company,” “we,” “us,” and “our” are to Bronco Drilling Company, Inc., a Delaware corporation, and its consolidated subsidiaries.

1. Organization and Summary of Significant Accounting Policies

Business and Principles of Consolidation

Bronco Drilling Company, Inc. provides contract land drilling and workover services to oil and natural gas exploration and production companies. The accompanying consolidated financial statements include the Company’s accounts and the accounts of its wholly owned subsidiaries.   Investments in unconsolidated subsidiaries representing ownership of at least 20%, but less than 50%, are accounted for under the equity method.  All intercompany accounts and transactions have been eliminated in consolidation.

The Company has prepared the accompanying unaudited consolidated financial statements and related notes in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions of Form 10-Q and Regulation S-X. In preparing the financial statements, the Company made various estimates and assumptions that affect the amounts of assets and liabilities the Company reports as of the dates of the balance sheets and amounts the Company reports for the periods shown in the consolidated statements of operations, stockholders’ equity and cash flows. The Company’s actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant changes in the near term relate to the Company’s recognition of revenues and accrued expenses, estimate of the allowance for doubtful accounts, estimate of asset impairments, estimate of deferred taxes and determination of depreciation and amortization expense.

In management’s opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the financial position of the Company as of June 30, 2008, the related results of operations for the three months and six months ended June 30, 2008 and 2007 and the cash flows for the six months ended June 30, 2008 and 2007.  The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.

The results of operations for the three months and six months ended June 30, 2008 are not necessarily an indication of the results expected for the full year.

A summary of the significant accounting policies consistently applied in the preparation of the accompanying consolidated financial statements follows.

Cash and Cash Equivalents

The Company considers all highly liquid debt instruments purchased with a maturity of three months or less and money market mutual funds to be cash equivalents.

The Company maintains its cash and cash equivalents in accounts and instruments which may not be federally insured. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risks on cash and cash equivalents.
 
Property and Equipment

Property and equipment, including renewals and betterments, are capitalized and stated at cost, while maintenance and repairs are expensed currently. Assets are depreciated on a straight-line basis. The depreciable lives of drilling rigs and related equipment are three to 15 years. The depreciable life of other equipment is three years. Depreciation is not commenced until acquired or refurbished rigs are placed in service. Once placed in service, depreciation continues when rigs are being repaired, refurbished or between periods of deployment. Assets not placed in service and not being depreciated were $42,213 and $61,604 as of June 30, 2008 and December 31, 2007, respectively.  Due to immateriality, gains and losses on dispositions are included in contract drilling and well service revenues.

The Company capitalizes interest as a component of the cost of drilling rigs constructed for its own use. For the six months ended June 30, 2008 and 2007, the Company capitalized $459 and $903, respectively, and for the three months ended June 30, 2008 and 2007, the Company capitalized $77 and $449, respectively, of interest costs incurred during the construction periods of certain drilling rigs.

The Company reviews long-lived assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the sum of the undiscounted expected future cash flows is less than the carrying amount of the assets, the Company recognizes an impairment loss based upon fair value of the asset.

Income Taxes

Pursuant to Statement of Financial Accounting Standards (“SFAS”) No. 109, “ Accounting for Income Taxes, ” the Company follows the asset and liability method of accounting for income taxes, under which the Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  Deferred tax assets and liabilities were measured using enacted tax rates expected to apply to taxable income in the years in which the Company expects to recover or settle those temporary differences.  A statutory Federal tax rate of 35% and effective state tax rate of 3.7% (net of Federal income tax effects) were used for the enacted tax rates for all periods.

As changes in tax laws or rates are enacted, deferred income tax assets and liabilities are adjusted through the provision for income taxes.  Deferred tax assets are reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.  The classification of current and noncurrent deferred tax assets and liabilities is based primarily on the classification of the assets and liabilities generating the difference.

The Company adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109 (“FIN 48”), on January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company is continuing its practice of recognizing interest and/or penalties related to income tax matters as income tax expense. As of June 30, 2008, the tax years ended December 31, 2004 through December 31, 2006 are open for examination by U.S. taxing authorities.

Net Income Per Common Share

The Company computes and presents net income per common share in accordance with SFAS No. 128, “ Earnings per Shar e.” This standard requires dual presentation of basic and diluted net income per share on the face of the Company’s statement of operations. Basic net income per common share is computed by dividing net income or loss attributable to common stock by the weighted average number of common shares outstanding for the period. Diluted net income per common share reflects the potential dilution that could occur if options or other contracts to issue common stock were exercised or converted into common stock.

Stock-based Compensation

The Company adopted SFAS No. 123(R), “ Share-Based Payment ” upon granting its first stock options on August 16, 2005. SFAS No. 123(R) requires a public entity to measure the costs of employee services received in exchange for an award of equity or liability instruments based on the grant-date fair value of the award. That cost will be recognized over the periods during which an employee is required to provide service in exchange for the award.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157 (“SFAS 157”), “ Fair Value Measurements .”  This Statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (“GAAP”), and expands disclosures about fair value measurements. This Statement applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, this Statement does not require any new fair value measurements. This Statement is effective for fiscal years beginning after November 15, 2007; however, on February 12, 2008, the FASB issued FSP FAS No. 157-2, Effective Dates of FASB Statement No. 157, which delays the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis.  The adoption of the provisions of SFAS 157 did not have a material impact on the Company’s financial statements.
 
In February 2007, the FASB issued SFAS No. 159 (“SFAS 159”), “ The Fair Value Option for Financial Assets and Financial Liabilities−Including an amendment of FASB Statement No. 115 .” SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings at each subsequent reporting date. SFAS No. 159 is effective for fiscal years beginning January 1, 2008. The adoption of the provisions of SFAS 159 did not have a material impact on the Company’s financial statements.

In December 2007, the FASB issued SFAS No. 141 (revised 2007) “ Business Combinations ” (“SFAS 141R”). SFAS 141R establishes principles and requirements for how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree. SFAS 141R also provides guidance for recognizing and measuring the goodwill acquired in the business combination and determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS No. 141R applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. The Company is currently evaluating the potential impact, if any, of the adoption of SFAS 141R on its consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160 (“SFAS 160”), “ Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51. ” SFAS 160 establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. SFAS 160 requires retroactive adoption of the presentation and disclosure requirements for existing minority interests. All other requirements of SFAS 160 shall be applied prospectively. SFAS 160 is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008.  The Company is currently evaluating the potential impact of the adoption of SFAS 160 on its consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161 (“SFAS 161”), “Disclosures about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133.”  SFAS 161 requires enhanced disclosures for derivative instruments and hedging activities that include how and why an entity uses derivatives, how instruments and the related hedged items are accounted for under FAS 133 and related interpretations, and how derivative instruments and related hedged items affect the entity’s financial position, results of operations and cash flows.  SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The Company does not expect the adoption of SFAS 161 to have a material impact on its financial position or results of operations.

2. Acquisitions
 
On January 9, 2007, the Company completed the acquisition of 31 workover rigs, 24 of which were in service at the time of the acquisition, from Eagle Well Service, Inc. (“Well Service”) and related subsidiaries for $2,567 in cash, 1,070,390 shares of our common stock with a fair market value of $15,125, and the assumption of debt of $6,527, liabilities of $678, and additional deferred income taxes of $7,188.  This acquisition provided a platform for the Company to expand into the well service industry.  The Company acquired the stock of Well Service, which was accounted for using the purchase method of accounting.  The deferred tax liability assumed in the acquisition was the main factor that resulted in the Company recording goodwill, all of which is not deductible for tax purposes.  The amortizable intangibles acquired include trade name and customer lists, which will be amortized over two and five years, respectively.  The operations related to the Well Service acquisition are included in the Company’s statement of operations as of the respective closing date.

The following table summarizes the final allocation of purchase price to the Company’s acquisition of Well Service:

The Company also sold to Challenger four drilling rigs and ancillary equipment.  The sales price of $12,990 consisted of $1,950 in cash, installment receivable of $1,500 and a term note of $9,540.  The installment receivable and term note bear interest at 8.5%.  Interest and principal payments of $909 on the note are due quarterly until maturity at December 31, 2010.  The note receivable is collateralized by the assets sold to Challenger.

The Company recorded a net gain of $3,200 relating to the contribution and sale of rigs and equipment to Challenger.  The transactions were completed on January 4, 2008.  Prior to these transactions, Challenger owned a fleet of 23 rigs.

At June 30, 2008, the book value of our ordinary share investment in Challenger was $76,876.  The Company’s 25% share of the net assets of Challenger was estimated to be $35,523.  The Company is in the process of gathering additional information in order to finalize the accounting treatment related to these transactions, including the allocation of the difference between the amount of the Company’s investment and the amount of the underlying equity in the net assets of Challenger.

The obligations under the revolving credit facility and the related guarantees are secured by a first priority security interest in substantially all of our assets, as well as the shares of capital stock of our direct and indirect subsidiaries.

The revolving credit facility contains customary covenants for facilities of this type, including among other things, covenants that restrict the Company’s ability to make capital expenditures, incur indebtedness, incur liens, dispose of property, repay debt, pay dividends, repurchase shares and make certain acquisitions. The financial covenants are a minimum fixed charge coverage ratio of 1.75 to 1.00 and a maximum total leverage ratio of 2.00 to 1.00. The Company was in compliance with all covenants at June 30, 2008.  The revolving credit facility provides for mandatory prepayments under certain circumstances.

6. Commitments and Contingencies

Following the announcement of the merger agreement on January 24, 2008, three purported class action complaints were filed challenging the proposed merger between Allis-Chalmers Energy Inc. (“Allis-Chalmers”), the Company and Elway Merger Sub, Inc. (“Merger Sub”). Two complaints were filed in Oklahoma in the District Court of Oklahoma County, the first on January 29, 2008 (the “Boothe action”), and the second on February 28, 2008 (the “Goff action”). The defendants named in both actions are the Company, the board of directors of the Company and Allis-Chalmers. On April 9, 2008, the Boothe action and the Goff action were consolidated into a single action (together, the “Oklahoma action”). The defendants named in the Oklahoma action are the Company, the board of directors of the Company and Allis-Chalmers. The third complaint was filed in the Delaware Court of Chancery on January 29, 2008 (the “Delaware action”). The defendants named in the Delaware action are the Company, the board of directors of the Company, Allis-Chalmers and Merger Sub.
 
The Oklahoma and Delaware actions generally allege that the proposed merger consideration is inadequate, that the board of directors of the Company breached its fiduciary duties and that Allis-Chalmers has aided and abetted the Company board of directors’ alleged breaches of fiduciary duties. The actions also allege that the preliminary joint proxy statement/prospectus included as part of Allis-Chalmers’ registration statement on Form S-4, filed with the SEC on February 20, 2008, contains materially incomplete and misleading information. The actions generally request, among other things, that the suits be designated class actions on behalf of the Company’s stockholders, that the proposed merger be enjoined and that the board of directors of the Company undertake an auction of the Company or otherwise take action to maximize stockholder value. Additionally, the Delaware action requests that all allegedly misleading or omitted information be corrected in Allis-Chalmers’ preliminary joint proxy statement/prospectus. The Delaware action seeks monetary damages for the Company’s stockholders and the Oklahoma action requests that the proposed merger be rescinded if it is consummated.

Allis-Chalmers and the Company filed motions to dismiss the Boothe action on February 21, 2008 and February 19, 2008, respectively. In response to these motions, the parties to the Boothe action agreed to extend the time for the plaintiff to amend his complaint, and for the defendants to amend or withdraw their motions to dismiss, or file answers to the amended complaint. After the Boothe action and the Goff action were consolidated into the Oklahoma action on April 9, 2008, the plaintiffs in the Oklahoma action filed a consolidated amended complaint on April 17, 2008. Allis-Chalmers filed a motion to dismiss the amended complaint on May 14, 2008, and the Company and the board of directors of the Company filed a motion to dismiss the amended complaint on May 19, 2008. In response to these motions, the parties to the Oklahoma action agreed to extend the time for the plaintiffs to respond to the defendants’ motions to dismiss. Under the agreement, the plaintiffs must respond by September 3, 2008. Discovery in the Oklahoma action is ongoing at this time.

The plaintiff in the Delaware action filed an amended complaint on April 23, 2008. The parties to the Delaware action agreed to indefinitely extend the time for the defendants to respond to the plaintiff’s amended complaint. Under the agreement, no defendant must answer the plaintiff’s amended complaint or otherwise respond until one of the following two events occurs: (1) the plaintiff files a second amended complaint, in which case the defendants will have 30 days from the date of service to answer the second amended complaint or otherwise respond; or (2) the plaintiff provides written notice to all the defendants that each defendant must answer the amended complaint, in which case each defendant will have, upon receiving the written notice, 30 days to answer the amended complaint or otherwise respond. Discovery in the Delaware action is ongoing at this time.

Allis-Chalmers, the Company, the board of directors of the Company and Merger Sub deny the substantive allegations in the two complaints, believe the claims asserted are baseless and intend to vigorously defend these actions.  As of this time, no order has been issued in either proceeding that would preclude the consummation of the merger.  Each of Allis-Chalmers and the Company has the right to terminate the merger agreement in the event a court enjoins the consummation of the merger.

Various other claims and lawsuits, incidental to the ordinary course of business, are pending against the Company. In the opinion of management, all matters are adequately covered by insurance or, if not covered, are not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

7. Business Segments

9. Equity Transactions
     
     In March 2007, the Company closed a public offering of 3,450,000 shares of common stock at a price of $22.75 per share. In the offering, a total of 1,700,000 shares were sold by the Company and 1,750,000 shares were sold by the selling stockholder.  The offering resulted in net proceeds to the Company of approximately $36,229, excluding offering expenses of $577. The Company did not receive any proceeds from the sale of shares by the selling stockholder.
 
     Effective January 9, 2007, the Company issued 1,070,390 shares of common stock to the equity owners of Eagle in connection with the Company’s acquisition of Eagle.

10. Stock Options and Stock Option Plan
 
     The Company’s 2005 Stock Incentive Plan was adopted on July 20, 2005 and amended on November 16, 2005 (the “2005 Plan”). The compensation cost that has been charged against income before taxes related to stock options was $480 and $1,007 for the three and six months ended June 30, 2007, respectively.  These options are reported as equity instruments and their fair value is amortized to expense using the straight line method over the vesting period. The shares of stock issued upon the exercise of the options will be from authorized but unissued common stock.

The Company receives a tax deduction for certain stock option exercises during the period the options are exercised, generally for the excess of the price at which the options are sold over the exercise price of the options. There have been no stock options exercised under the 2005 Plan.

The purpose of the 2005 Plan was to enable the Company, and any of its affiliates, to attract and retain the services of the types of employees, consultants and directors who will contribute to its long-range success and to provide incentives which are linked directly to increases in share value which will inure to the benefit of the Company’s stockholders. The 2005 Plan provided a means by which eligible recipients of awards may be given an opportunity to benefit from increases in value of the Company’s common stock through the granting of incentive stock options and nonstatutory stock options. Eligible award recipients under the 2005 Plan were employees, consultants and directors of the Company and its affiliates. Incentive stock options under the 2005 Plan could be granted only to employees. Awards other than incentive stock options under the 2005 Plan could be granted to employees, consultants and directors. The shares that may be issued upon exercise of the options will be from authorized but unissued common stock, and the maximum aggregate amount of such common stock which could be issued upon exercise of all awards under the plan, including incentive stock options, could not exceed 1,000,000 shares, subject to adjustment to reflect certain corporate transactions or changes in the Company’s capital structure.

The Company’s board of directors and a majority of the Company’s stockholders approved the Company’s 2006 Stock Incentive Plan (the “2006 Plan,” and together with the 2005 Plan, the “Plans”), effective April 20, 2006.  No further awards will be made under the 2005 Plan.  The purpose of the 2006 Plan is to provide a means by which eligible recipients of awards may be given an opportunity to benefit from increases in value of the Company’s common stock through the granting of one or more of the following awards: (1) incentive stock options, (2) nonstatutory stock options, (3) restricted awards, (4) performance awards and (5) stock appreciation rights.  The maximum aggregate amount of the Company’s common stock which may be issued upon exercise of all awards under the 2006 Plan, may not exceed 2,500,000 shares, less shares underlying options granted to employees under the 2005 Plan prior to the adoption of the 2006 Plan.  There have been no stock options exercised under the 2006 Plan.

On April 20, 2007, the Company filed a Tender Offer Statement on Schedule TO relating to the Company’s offer to twenty-five eligible directors, officers, employees and consultants to exchange certain outstanding options to purchase shares of the Company’s common stock for restricted stock awards consisting of the right to receive restricted shares of the Company’s common stock (the “Restricted Stock Awards”). The offer expired on May 21, 2007. Pursuant to the offer, the Company accepted for cancellation eligible options to purchase 729,000 shares of the Company’s common stock tendered by directors, officers, employees and consultants eligible to participate in the offer.  Subject to the terms and conditions of the offer, on May 21, 2007 the Company granted one Restricted Stock Award in exchange for every two shares of common stock underlying the eligible options tendered.  The Restricted Stock Awards will vest in equal amounts on January 1, 2008 and January 1, 2009, subject to earlier vesting or forfeiture in certain circumstances. The Company granted the Restricted Stock Awards under the 2006 Plan.
 
An incremental cost was computed in accordance with SFAS No. 123(R) upon the conversion of options to restricted stock.  The incremental cost was measured as the excess of the fair value of the modified award over the fair value to the original award immediately preceding conversion, measured based on the share price and other pertinent factors at that date.  The incremental cost to be recognized over the vesting period of the modified award is $387.
 
The fair value of each option award is estimated on the date of grant using a Black-Scholes valuation model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatility of a selected peer. The majority of the Company’s options were held by employees that made up one group with similar expected exercise behavior for valuation purposes. The expected term of options granted is estimated based on an average of the vesting period and the contractual period. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant.

Under the 2005 Plan, employee stock options become exercisable in equal monthly installments over a three-year period, and all options generally expire ten years after the date of grant. Under the 2006 Plan, employee stock options become exercisable to the extent the options have become vested pursuant to the vesting schedule set forth in the applicable stock option award certificate, and all options generally expire ten years after the date of grant.  The Plans provide that all options must have an exercise price not less than the fair market value of the Company’s common stock on the date of the grant. The Company did not have any outstanding options at June 30, 2008.

The Company has not declared dividends since it became a public company and does not intend to do so in the foreseeable future, and thus did not use a dividend yield. Expected life has been determined using the permitted simplified method.  In each case, the actual value that will be realized, if any, will depend on the future performance of the common stock and overall stock market conditions. There is no assurance that the value an optionee actually realizes will be at or near the value estimated using the Black–Scholes model.

     Under all restricted stock awards to date, shares were issued when granted and nonvested shares are subject to forfeiture for failure to fulfill service conditions.  Restricted stock awards are valued at the grant date market value of the underlying common stock and are being amortized to operations over the respective vesting period.  Compensation expense for the three and six months ended June 30, 2008, related to shares of restricted stock was $1,438 and $2,588, respectively, and for the three and six months ended June 30, 2007 was $501 and $666, respectively.  Restricted stock activity for the six months ended June 30, 2008 was as follows:

Overview
 
     We provide contract land drilling and workover services to oil and natural gas exploration and production companies. As of July 31, 2008, we owned a fleet of 56 land drilling rigs, of which 45 were marketed and 11 were held in inventory. We also owned a fleet of 61 workover rigs, of which 56 were operating and five were in the process of being manufactured. As of July 31, 2008, we also owned a fleet of 70 trucks used to transport our rigs.
 
     We commenced operations in 2001 with the purchase of one stacked 650-horsepower drilling rig that we refurbished and deployed. We subsequently made selective acquisitions of both operational and inventoried drilling rigs, as well as ancillary equipment. Our management team has significant experience not only with acquiring rigs, but also with refurbishing and deploying inventoried rigs. We have successfully refurbished and brought into operation 25 inventoried drilling rigs during the period from November 2003 through December 2007. In addition, we have a 41,000 square foot machine shop in Oklahoma City, which allows us to refurbish and repair our rigs and equipment in-house. This facility, which complements our three drilling rig refurbishment yards, significantly reduces our reliance on outside machine shops and the attendant risk of third-party delays in our rig refurbishment program.
 
     We currently operate our drilling rigs in Oklahoma, Texas, Colorado, Utah, North Dakota, and Louisiana.  Our workover rigs are currently operating in Oklahoma, Texas, Kansas, Colorado and New Mexico.  A majority of the wells we have drilled for our customers have been drilled in search of natural gas reserves. Natural gas is often found in deep and complex geologic formations that generally require higher horsepower, premium rigs and experienced crews to reach targeted depths. Our current fleet of 56 rigs includes 36 rigs ranging from 950 to 2,500 horsepower. Accordingly, such rigs can, or in the case of inventoried rigs upon refurbishment, will be able to, reach the depths required to explore for deep natural gas reserves. Our higher horsepower land drilling rigs can also drill horizontal wells, which are increasing as a percentage of total wells drilled in North America. We believe our premium rig fleet, inventory and experienced crews position us to benefit from the natural gas drilling activity in our core operating areas.

     On January 23, 2008, we entered into a merger agreement, as amended by the First Amendment thereto, dated as of June 1, 2008, which we refer to collectively as the merger agreement with Allis-Chalmers Energy Inc., which we refer to as Allis-Chalmers, providing for the acquisition of us by Allis-Chalmers.  Pursuant to the merger agreement, we and Allis-Chalmers agreed that, subject to the satisfaction of several closing conditions (including approval by each company’s stockholders), Bronco would merge with and into Elway Merger Sub, LLC., a wholly-owned subsidiary of Allis-Chalmers, which we refer to as Merger Sub, and Merger Sub would survive the merger and simultaneously change its name to “Bronco Drilling Company LLC”.  The merger agreement was approved by our board of directors and by the respective boards of directors of Allis-Chalmers and Merger Sub.
 
     The merger agreement provides that at the effective time of the merger, our stockholders will receive merger consideration comprised of (1) $200.0 million in cash and (2) 16,846,500 shares of Allis-Chalmers common stock.  For more information regarding the merger, please refer to the joint proxy statement/prospectus of Allis-Chalmers and Bronco filed by Allis-Chalmers with the SEC on July 15, 2008, and other relevant materials concerning the proposed merger that ­­­have been or will be filed by us or Allis-Chalmers with the SEC.
 
     We earn our contract drilling revenues by drilling oil and natural gas wells for our customers. We obtain our contracts for drilling oil and natural gas wells either through competitive bidding or through direct negotiations with customers. Our drilling contracts generally provide for compensation on either a daywork or footage basis. We have not historically entered into turnkey contracts and do not intend to enter into turnkey contracts, subject to changes in market conditions, although it is possible that we may acquire such contracts in connection with future acquisitions. Contract terms we offer generally depend on the complexity and risk of operations, the on-site drilling conditions, the type of equipment used and the anticipated duration of the work to be performed. Although we currently have 19 of our rigs operating under agreements with durations of up to two years, our contracts generally provide for the drilling of a single well and typically permit the customer to terminate on short notice.
 
     A significant performance measurement in our industry is operating rig utilization. We compute operating rig utilization rates by dividing revenue days by total available days during a period. Total available days are the number of calendar days during the period that we have owned the operating rig. Revenue days for each operating rig are days when the rig is earning revenues under a contract, i.e. when the rig begins moving to the drilling location until the rig is released from the contract. On daywork contracts, during the mobilization period we typically earn a fixed amount of revenue based on the mobilization rate stated in the contract. We begin earning our contracted daywork rate when we begin drilling the well. Occasionally, in periods of increased demand, we will receive a percentage of the contracted dayrate during the mobilization period. We account for these revenues as mobilization fees.
 
     For the three and six months ended June 30, 2008 and 2007 and for the years ended December 31, 2007, 2006 and 2005, our rig utilization rates, revenue days and average number of operating rigs were as follows:

Utilization Rates
    82 %     76 %     76 %     78 %     76 %     93 %     95 %
 
     The decrease in the number of revenue days in the six month-period ended June 30, 2008 as compared to the same period in 2007 is attributable to a decrease in our rig utilization rate and average number of operating rigs due primarily to the rigs sold and contributed to Challenger.  See “—Recent Highlights” below.
 
Market Conditions in Our Industry
 
The United States contract land drilling services industry is highly cyclical. Volatility in oil and natural gas prices can produce wide swings in the levels of overall drilling activity in the markets we serve and affect the demand for our drilling services and the dayrates we can charge for our rigs. The availability of financing sources, past trends in oil and natural gas prices and the outlook for future oil and natural gas prices strongly influence the number of wells oil and natural gas exploration and production companies decide to drill.
 
The following table depicts the prices for near month delivery contracts for crude oil and natural gas as traded on the NYMEX, as well as the most recent Baker Hughes domestic land rig count, on the dates indicated:

U.S. Land Rig Count

We believe capital spent on incremental natural gas production will be driven by an increase in hydrocarbon demand as well as changes in supply of natural gas. The Energy Information Administration estimated that U.S. consumption of natural gas exceeded domestic production by 16% in 2005 and forecasts that U.S. consumption of natural gas will exceed U.S. domestic production by 24% in 2010. In addition, a study published by the National Petroleum Council in September 2003 concluded from drilling and production data over the preceding ten years that average “initial production rates from new wells have been sustained through the use of advanced technology; however, production declines from these initial rates have increased significantly; and recoverable volumes from new wells drilled in mature producing basins have declined over time.” The report went on to state that “without the benefit of new drilling, indigenous supplies have reached a point at which U.S. production declines by 25% to 30% each year” and predicted that in ten years eighty percent of gas production “will be from wells yet to be drilled.” We believe all of these factors tend to support a higher natural gas price environment, which should create strong incentives for oil and natural gas exploration and production companies to increase drilling activity in the U.S. Consequently, these factors may result in higher rig dayrates and rig utilization.

Critical Accounting Policies and Estimates
 
Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting policies that are described in the notes to our consolidated financial statements. The preparation of the consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We continually evaluate our judgments and estimates in determining our financial condition and operating results. Estimates are based upon information available as of the date of the financial statements and, accordingly, actual results could differ from these estimates, sometimes materially. Critical accounting policies and estimates are defined as those that are both most important to the portrayal of our financial condition and operating results and require management’s most subjective judgments. The most critical accounting policies and estimates are described below.
 
Revenue and Cost Recognition —We earn our revenues by drilling oil and natural gas wells for our customers under daywork or footage contracts, which usually provide for the drilling of a single well. We recognize revenues on daywork contracts for the days completed based on the dayrate each contract specifies. Mobilization revenues and costs are deferred and recognized over the drilling days of the related drilling contract. Individual contracts are usually completed in less than 120 days. We follow the percentage-of-completion method of accounting for footage contract drilling arrangements. Under this method, drilling revenues and costs related to a well in progress are recognized proportionately over the time it takes to drill the well. Percentage of completion is determined based upon the amount of expenses incurred through the measurement date as compared to total estimated expenses to be incurred drilling the well. Mobilization costs are not included in costs incurred for percentage-of-completion calculations. Mobilization costs on footage contracts and daywork contracts are deferred and recognized over the days of actual drilling. Under the percentage-of-completion method, management estimates are relied upon in the determination of the total estimated expenses to be incurred drilling the well. When estimates of revenues and expenses indicate a loss on a contract, the total estimated loss is accrued.
 
Our management has determined that it is appropriate to use the percentage-of-completion method to recognize revenue on our footage contracts, which is the predominant practice in the industry. Although our footage contracts do not have express terms that provide us with rights to receive payment for the work that we perform prior to drilling wells to the agreed upon depth, we use this method because, as provided in applicable accounting literature, we believe we achieve a continuous sale for our work-in-progress and we believe, under applicable state law, we ultimately could recover the fair value of our work-in-progress even in the event we were unable to drill to the agreed upon depth in breach of the applicable contract. However, ultimate recovery of that value, in the event we were unable to drill to the agreed upon depth in breach of the contract, would be subject to negotiations with the customer and the possibility of litigation.
 
We are entitled to receive payment under footage contracts when we deliver to our customer a well completed to the depth specified in the contract, unless the customer authorizes us to drill to a shallower depth. Since inception, we have completed all our footage contracts. Although our initial cost estimates for footage contracts do not include cost estimates for risks such as stuck drill pipe or loss of circulation, we believe that our experienced management team, our knowledge of geologic formations in our areas of operations, the condition of our drilling equipment and our experienced crews enable us to make reasonably dependable cost estimates and complete contracts according to our drilling plan. While we do bear the risk of loss for cost overruns and other events that are not specifically provided for in our initial cost estimates, our pricing of footage contracts takes such risks into consideration. When we encounter, during the course of our drilling operations, conditions unforeseen in the preparation of our original cost estimate, we immediately adjust our cost estimate for the additional costs to complete the contracts. If we anticipate a loss on a contract in progress at the end of a reporting period due to a change in our cost estimate, we immediately accrue the entire amount of the estimated loss, including all costs that are included in our revised estimated cost to complete that contract, in our consolidated statement of operations for that reporting period.  We are more likely to encounter losses on footage contracts in years in which revenue rates are lower for all types of contracts.
 
Revenues and costs during a reporting period could be affected by contracts in progress at the end of a reporting period that have not been completed before our financial statements for that period are released. We had no footage contracts in progress at June 30, 2008 and December 31, 2007. At June 30, 2008 and December 31, 2007, our contract drilling in progress totaled $1.4 million and $2.1 million, respectively, all of which relates to the revenue recognized but not yet billed or costs deferred on daywork contracts in progress.
 
We accrue estimated contract costs on footage contracts for each day of work completed based on our estimate of the total costs to complete the contract divided by our estimate of the number of days to complete the contract. Contract costs include labor, materials, supplies, repairs and maintenance and operating overhead allocations. In addition, the occurrence of uninsured or under-insured losses or operating cost overruns on our footage contracts could have a material adverse effect on our financial position and results of operations. Therefore, our actual results could differ significantly if our cost estimates are later revised from our original estimates for contracts in progress at the end of a reporting period that were not completed prior to the release of our financial statements.
 
Accounts Receivable —We evaluate the creditworthiness of our customers based on their financial information, if available, information obtained from major industry suppliers, current prices of oil and natural gas and any past experience we have with the customer. Consequently, an adverse change in those factors could affect our estimate of our allowance for doubtful accounts. In some instances, we require new customers to establish escrow accounts or make prepayments. We typically invoice our customers at 30-day intervals during the performance of daywork contracts and upon completion of the daywork contract. Footage contracts are invoiced upon completion of the contract. Our typical contract provides for payment of invoices in 10 to 30 days. We generally do not extend payment terms beyond 30 days. We are currently involved in legal actions to collect various overdue accounts receivable.  Our allowance for doubtful accounts was $1.2 million and $1.8 million at June 30, 2008 and December 31, 2007, respectively. Any allowance established is subject to judgment and estimates made by management. We determine our allowance by considering a number of factors, including the length of time trade accounts receivable are past due, our previous loss history, our customer’s current ability to pay its obligation to us and the condition of the general economy and the industry as a whole. We write off specific accounts receivable when they become uncollectible and payments subsequently received on such receivables reduce the allowance for doubtful accounts.
 
If a customer defaults on its payment obligation to us under a footage contract, we would need to rely on applicable law to enforce our lien rights, because our footage contracts do not expressly grant to us a security interest in the work we have completed under the contract and we have no ownership rights in the work-in-progress or completed drilling work, except any rights arising under the applicable lien statute on foreclosure. If we were unable to drill to the agreed on depth in breach of the contract, we might also need to rely on equitable remedies outside of the contract, including quantum meruit, available in applicable courts to recover the fair value of our work-in-progress under a footage contract.
 
Asset Impairment and Depreciation —We review long-lived assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.  We also evaluate the carrying value of goodwill during the fourth quarter of each year and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value below its carrying amount.  Factors that we consider important and could trigger an impairment review would be our customers’ financial condition and any significant negative industry or economic trends. More specifically, among other things, we consider our contract revenue rates, our rig utilization rates, cash flows from our drilling rigs, current oil and natural gas prices, industry analysts’ outlook for the industry and their view of our customers’ access to debt or equity and the trends in the price of used drilling equipment observed by our management. If a review of our drilling rigs, intangible assets and goodwill indicate that our carrying value exceeds the estimated undiscounted future cash flows, we are required under applicable accounting standards to write down the drilling equipment, intangible assets and goodwill to its fair market value. A one percent write-down in the cost of our drilling equipment, intangible assets, and goodwill, at June 30, 2008, would have resulted in a corresponding decrease in our net income of approximately $2.7 million.
 
Our determination of the estimated useful lives of our depreciable assets, directly affects our determination of depreciation expense and deferred taxes. A decrease in the useful life of our drilling equipment would increase depreciation expense and reduce deferred taxes. We provide for depreciation of our drilling rigs, transportation and other equipment on a straight-line method over useful lives that we have estimated and that range from three to fifteen years after the rig was placed into service. We record the same depreciation expense whether an operating rig is idle or working. Depreciation is not recorded on an inventoried rig until placed in service. Our estimates of the useful lives of our drilling, transportation and other equipment are based on our experience in the drilling industry with similar equipment.
 
We capitalize interest cost as a component of drilling and workover rigs refurbished for our own use. During the three and six months ended June 30, 2008, we capitalized approximately $77,000 and $459,000, respectively, and during the three and six months ended June 30, 2007 we capitalized approximately $449,000 and $903,000, respectively.
 
Stock Based Compensation--- We have adopted SFAS No. 123(R), “ Share-Based Payment ” upon granting our first stock options on August 16, 2005. SFAS No. 123(R) requires a public entity to measure the costs of employee services received in exchange for an award of equity or liability instruments based on the grant-date fair value of the award. That cost will be recognized over the periods during which an employee is required to provide service in exchange for the award.  Stock compensation expense was $1.4 million and $2.6 million for the three and six months ended June 30, 2008, respectively, and $981,000 and $1.7 million for the three and six months ended June 30, 2007, respectively.
 
The fair value of each option award is estimated on the date of grant using a Black Scholes valuation model that uses various assumptions related to volatility, expected life, forfeitures, exercise patterns, risk free rates and expected dividends. Expected volatilities are based on the historical volatility of a selected peer and other factors. The majority of our options were granted to employees that made up one group with similar expected exercise behavior for valuation purposes. The expected term of options granted was estimated based on an average of the vesting period and the contractual period. The risk-free rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of the grant.
 
We have not declared dividends since we became a public company and do not intend to do so in the foreseeable future, and thus did not use a dividend yield. Expected life has been determined using the permitted short cut method.

Under our 2005 Stock Incentive Plan, employee stock options become exercisable in equal monthly installments over a three-year period, and all options generally expire ten years after the date of grant. The 2005 Plan provides that all options must have an exercise price not less than the fair market value of our common stock on the date of the grant.

On April 20, 2007, we filed a Tender Offer Statement on Schedule TO relating to our offer to twenty-five eligible directors, officers, employees and consultants to exchange certain outstanding options to purchase shares of our common stock for restricted stock awards consisting of the right to receive restricted shares of our common stock, which we refer to as the “restricted stock awards.” The offer expired on May 21, 2007. Pursuant to the offer, we accepted for cancellation eligible options to purchase 729,000 shares of our common stock tendered by directors, officers, employees and consultants eligible to participate in the offer.  Subject to the terms and conditions of the offer, on May 21, 2007 we granted one restricted stock award in exchange for every two shares of common stock underlying the eligible options tendered.  Half of the restricted stock awards vested on January 1, 2008 and the balance vest on January 1, 2009, subject to earlier vesting or forfeiture in certain circumstances. We granted the restricted stock awards under our 2006 Stock Incentive Plan, effective as of April 20, 2006.

An incremental cost was computed in accordance with SFAS No. 123(R) upon the conversion of options to restricted stock.  The incremental cost was measured as the excess of the fair value of the modified award over the fair value to the original award immediately preceding conversion, measured based on the share price and other pertinent factors at that date.  The incremental cost to be recognized over the vesting period of the modified award is $387,000.
 
Deferred Income Taxes —We provide deferred income taxes for the basis difference in our property and equipment, stock compensation expense and other items between financial reporting and tax reporting purposes. For property and equipment, basis differences arise from differences in depreciation periods and methods and the value of assets acquired in a business acquisition where we acquire the stock in an entity rather than just its assets. For financial reporting purposes, we depreciate the various components of our drilling rigs and refurbishments over fifteen years, while federal income tax rules require that we depreciate drilling rigs and refurbishments over five years. Therefore, in the first five years of our ownership of a drilling rig, our tax depreciation exceeds our financial reporting depreciation, resulting in our providing deferred taxes on this depreciation difference. After five years, financial reporting depreciation exceeds tax depreciation, and the deferred tax liability begins to reverse.
 
Other Accounting Estimates —Our other accrued expenses as of June 30, 2008 and December 31, 2007 included accruals of approximately $2.7 million and $3.0 million, respectively, for costs under our workers’ compensation insurance. We have a deductible of $1.0 million per covered accident under our workers’ compensation insurance. We maintain letters of credit in the aggregate amount of $7.3 million for the benefit of various insurance companies as collateral for retrospective premiums and retained losses which may become payable under the terms of the underlying insurance contracts.  The letters of credit are typically renewed annually.  No amounts have been drawn under the letters of credit. At June 30, 2008 and December 31, 2007, we had deposits of $2.8 million and $2.7 million, respectively, with an insurance company collateralizing a letter of credit. We accrue for these costs as claims are incurred based on cost estimates established for each claim by the insurance companies providing the administrative services for processing the claims, including an estimate for incurred but not reported claims, estimates for claims paid directly by us, our estimate of the administrative costs associated with these claims and our historical experience with these types of claims.  We also have a self-insurance program for major medical, hospitalization and dental coverage for employees and their dependents.  We recognize both reported and incurred but not reported costs related to the self-insurance portion of our health insurance.  Since the accrual is based on estimates of expenses for claims, the ultimate amount paid may differ from accrued amounts.
 
     Recent Accounting Pronouncements In September 2006, the FASB issued SFAS No. 157, or SFAS 157, “ Fair Value Measurements .”  This Statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, or GAAP, and expands disclosures about fair value measurements. This Statement applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, this Statement does not require any new fair value measurements. This Statement is effective for fiscal years beginning after November 15, 2007; however, on February 12, 2008, the FASB issued FSP FAS No. 157-2, Effective Dates of FASB Statement No. 157, which delays the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis.  The adoption of the provisions of SFAS 157 did not have a material impact on our financial statements.
 
     In February 2007, the FASB issued SFAS No. 159, or SFAS 159, “ The Fair Value Option for Financial Assets and Financial Liabilities−Including an amendment of FASB Statement No. 115 .” SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings at each subsequent reporting date. SFAS No. 159 is effective for fiscal years beginning January 1, 2008. The adoption of the provisions of SFAS 159 did not have a material impact on our financial statements.
 
     In December 2007, the FASB issued SFAS No. 141 (revised 2007) “ Business Combinations ”, or SFAS 141R. SFAS 141R establishes principles and requirements for how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree. SFAS 141R also provides guidance for recognizing and measuring the goodwill acquired in the business combination and determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS No. 141R applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008.  We are currently evaluating the potential impact, if any, of the adoption of SFAS 141R on our consolidated financial statements.
 
     In December 2007, the FASB issued SFAS No. 160, or SFAS 160, “ Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51. ” SFAS 160 establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. SFAS 160 requires retroactive adoption of the presentation and disclosure requirements for existing minority interests. All other requirements of SFAS 160 shall be applied prospectively. SFAS 160 is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008.  We are currently evaluating the potential impact, if any, of the adoption of SFAS 141R on our consolidated financial statements.
 
     In March 2008, the FASB issued SFAS No. 161, or SFAS 161, “Disclosures about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133.”  SFAS 161 requires enhanced disclosures for derivative instruments and hedging activities that include how and why an entity uses derivatives, how instruments and the related hedged items are accounted for under FAS 133 and related interpretations, and how derivative instruments and related hedged items affect the entity’s financial position, results of operations and cash flows.  SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. We do not expect the adoption of SFAS 161 to have a material impact on our financial position or results of operations.

Recent Highlights

The following are highlights that impacted our liquidity or results of operations for the six months ended June 30, 2008:
 
     On January 4, 2008, Bronco MENA Investments LLC, one of our wholly-owned subsidiaries, closed a transaction with Challenger Limited, or Challenger, a company organized under the laws of the Isle of Man, and certain of its affiliates to acquire a 25% equity interest in Challenger in exchange for six drilling rigs and $5.1 million in cash.  Challenger is an international provider of contract land drilling and workover services to oil and natural gas companies with its principal operations in Libya.  We also sold to Challenger four drilling rigs and ancillary equipment for $13.0 million, payable in installments.  We recorded a net gain of $3.2 million relating to the exchange and sale of rigs and equipment to Challenger.  The transactions were completed on January 4, 2008.  Prior to these transactions, Challenger owned a fleet of 23 rigs.  We recorded equity in (loss) income of investment of $(69,000) and $1.8 million for the three and six months ended June 30, 2008 related to our equity investment in Challenger.
 
     Eight of the rigs contributed or sold to Challenger are in Libya with three of the rigs currently operating.  Challenger is still in the process of securing a debt facility to meet short-term capital needs including those related to start-up of our rigs and to mitigate downtime that has affected Challenger’s operations due to past underinvestment in adequate rig supplies and spare equipment.  We believe that an entry into a debt facility by Challenger is an important factor in determining the long-term success of Challenger and anticipate that Challenger will continue to have unpredictable financial results in the near future.
 
     On January 23, 2008, we entered into a merger agreement, as amended by the First Amendment thereto, dated as of June 1, 2008, which we refer to collectively as the merger agreement, with Allis-Chalmers, providing for the acquisition of us by Allis-Chalmers.  Pursuant to the merger agreement, we and Allis-Chalmers agreed that, subject to the satisfaction of several closing conditions (including approval by each company’s stockholders), Bronco would merge with and into Elway Merger Sub, LLC, a wholly-owned subsidiary of Allis-Chalmers, which we refer to as Merger Sub, and Merger Sub would survive the merger and simultaneously change its name to “Bronco Drilling Company LLC”.  The merger agreement was approved by our board of directors and by the respective boards of directors of Allis-Chalmers and Merger Sub.
 
     The merger agreement provides that at the effective time of the merger, our stockholders will receive merger consideration comprised of (1) $200.0 million in cash and (2) 16,846,500 shares of Allis-Chalmers common stock.  For more information regarding the merger, please refer to the joint proxy statement/prospectus of Allis-Chalmers and Bronco filed by Allis-Chalmers with the SEC on July 15, 2008 and other relevant materials that have been or will be filed by us or Allis-Chalmers with the SEC.
 
     During the second quarter of 2008, we increased our number of term contracts and now have approximately 57% of our estimated revenue days for the last two quarters of 2008 and 32% of our estimated revenue days for 2009 covered by term contracts.  Total contracted revenue days do not include days attributable to our multi-well contracts, as we do not attempt to quantify the duration of those contracts.  Inclusion of such contracts would increase the percentages stated above.
 
     During the second quarter of 2008, we bid and won a tender in Mexico with Pemex.  This tender will require three rigs operating in the Chicontepec basin near Poza Rica, Mexico.  Two of the rigs have begun to mobilize to Mexico with the third to follow in the coming weeks.  We anticipate all three will operating in Mexico by the end of August.  The duration of the contract with Pemex for these rigs is through the end of 2009.
 
     We currently have six rigs contractually committed to the Bakken Shale.  All of these rigs will require winterization and other modifications.  Two of the rigs will require major modifications and refurbishment which will include a conversion from mechanical to electric power.  We expect these rigs to be deployed to the Bakken during the third and fourth quarters of 2008.
 
Results of Operations

Three Months Ended June 30, 2008 Compared to Three Months Ended June 30, 2007
 
     Contract Drilling Revenue.  For the three months ended June 30, 2008, we reported contract drilling revenues of $60.5 million, a 13% decrease from revenues of $69.3 million for the same period in 2007. The decrease is primarily due to a decrease in dayrates, revenue days and average number of rigs working for the three months ended June 30, 2008 as compared to the same period in 2007. Average dayrates for our drilling services decreased $1,464, or 8%, to $16,332 for the three months ended June 30, 2008 from $17,796 in the same period in 2007. Revenue days decreased 7% to 3,355 days for the three months ended June 30, 2008 from 3,624 days during the same period in 2007. Our average number of operating rigs decreased to 45 from 52, or 14%, for the three months ended June 30, 2008 as compared to the same period in 2007. The decrease in the number of revenue days and size of our operating rig fleet for the three months ended June 30, 2008, as compared to the same period in 2007, is primarily due to the sale and contribution of rigs to Challenger.
 
     Well Service Revenue.   For the three months ended June 30, 2008, we reported well service revenues of approximately $9.3 million, a 72% increase from revenues of $5.4 million for the same period in 2007.  The increase is primarily due to an increase in revenue hours and average number of operating workover rigs for the three months ended June 30, 2008 as compared to the same period in 2007.  Revenue hours increased 77% to 25,533 hours for the three months ended June 30, 2008 from 14,427 hours during the same period in 2007.  Our average number of operating workover rigs increased to 53 from 29, or 84%, for the three months ended June 30, 2008 as compared to the same period in 2007.  The increase in revenue hours and size of our operating workover rig fleet is due to additional workover rigs purchased.
 
     Equity in Loss of Investment.   Equity in loss of investment was $69,000 for the three months ended June 30, 2008 related to our investment in Challenger.  The loss was due to Challenger’s inability to meet short-term capital needs including those related to start-up of the Bronco rigs and to mitigate downtime that has plagued the company's operations due to past underinvestment in adequate rig supplies and spare equipment.  Challenger is in the process of securing a debt facility which is a pivotal component in determining the long-term success of Challenger.
 
     Contract Drilling Expense.  Direct rig cost decreased $3.8 million to $36.7 million for the three months ended June 30, 2008 from $40.5 million for the same period in 2007. This 9% decrease is primarily due to the decrease in revenue days and the decrease in average number of operating rigs in our fleet for the three months ended June 30, 2008 as compared to the same period in 2007.  As a percentage of contract drilling revenue, drilling expense increased to 61% for the three-month period ended June 30, 2008 from 58% for the same period in 2007 due primarily to a decrease in dayrates for the three months ended June 30, 2008 compared to the same period in 2007.
 
     Well Service Expense. Well service expense increased $2.8 million to $6.1 million for the three months ended June 30, 2008 from $3.3 million for the same period in 2007.  This 85% increase is primarily due to the increase in revenue hours and the average number of operating workover rigs in our fleet for the three months ended June 30, 2008 as compared to the same period in 2007.
 
     Depreciation Expense.  Depreciation expense increased $1.6 million to $12.5 million for the three months ended June 30, 2008 from $10.9 million for the same period in 2007. The increase is primarily due to the 4% increase in fixed assets.
 
     General and Administrative Expense . General and administrative expense increased $15,000 to $5.4 million for the three months ended June 30, 2008 from $5.4 million for the same period in 2007. The increase is the result of an increase in payroll costs of $535,000, an increase in stock compensation expense of $457,000, an increase in professional fees expense of $212,000, and an increase in rent expense of $72,000.  The increase in payroll costs is primarily due to our increased administrative employee count and related wage increases.  The increase in stock compensation expense is attributed to grants of restricted stock during 2007 and the six months ended June 30, 2008.  The increase in professional fees is due to services provided related to the Challenger transaction and merger agreement.  These increases were partially offset by a decrease in accounts receivable write offs of $1.2 million.
 
     Interest Expense . Interest expense increased $367,000 to $1.2 million for the three months ended June 30, 2008 from $795,000 for the same period in 2007. The increase is due to a decrease in the capitalization of interest related to our rig refurbishment program and a higher outstanding balance on our revolving credit facility, partially offset by a decrease in the average interest rate on our revolving credit facility  We capitalized $77,000 of interest for the three months ended June 30, 2008 as compared to $449,000 for the same period in 2007.
 
     Income Tax Expense . We recorded a tax expense of $2.7 million for the three months ended June 30, 2008, all of which was deferred tax expense. This compares to a deferred tax expense of $5.4 million for the three months ended June 30, 2007. This decrease is due to the decrease in pre-tax income. 

Six months Ended June 30, 2008 Compared to Six months Ended June 30, 2007
 
     Contract Drilling Revenue.  For the six months ended June 30, 2008, we reported contract drilling revenues of $114.6 million, a 20% decrease from revenues of $143.9 million for the same period in 2007. The decrease is primarily due to a decrease in dayrates, revenue days and average number of rigs working for the six months ended June 30, 2008 as compared to the same period in 2007. Average dayrates for our drilling services decreased $1,676, or 9%, to $16,591 for the six months ended June 30, 2008 from $18,267 in the same period in 2007. Revenue days decreased 15% to 6,203 days for the six months ended June 30, 2008 from 7,255 days during the same period in 2007. Our average number of operating rigs decreased to 45 from 52, or 13%, for the six months ended June 30, 2008 as compared to the same period in 2007. The decrease in the number of revenue days and size of our operating rig fleet for the six months ended June 30, 2008 as compared to the same period in 2007 is primarily due to the sale and contribution of rigs to Challenger.
 
     Well Service Revenue.   For the six months ended June 30, 2008, we reported well service revenues of approximately $17.5 million, a 78% increase from revenues of $9.8 million for the same period in 2007.  The increase is primarily due to an increase in revenue hours and average number of operating workover rigs for the six months ended June 30, 2008 as compared to the same period in 2007.  Revenue hours increased 87% to 49,398 hours for the six months ended June 30, 2008 from 26,474 hours during the same period in 2007.  Our average number of operating workover rigs increased to 51 from 27, or 89%, for the six months ended June 30, 2008 as compared to the same period in 2007.  The increase in revenue hours and size of our operating workover rig fleet is due to additional workover rigs purchased.
 
     Equity in Income of Investment.   Equity in income of investment was $1.8 million for the six months ended June 30, 2008 related to our investment in Challenger.  Challenger is still in the process of securing a debt facility to meet short-term capital needs including those related to start-up of our rigs and to mitigate downtime that has affected Challenger’s operations due to past underinvestment in adequate rig supplies and spare equipment.  The debt facility is a pivotal component in determining the long-term success of Challenger.
-16-

 
     Contract Drilling Expense.  Direct rig cost decreased $11.4 million to $69.9 million for the six months ended June 30, 2008 from $81.3 million for the same period in 2007. This 14% decrease is primarily due to the decrease in revenue days and the decrease in average number of operating rigs in our fleet for the six months ended June 30, 2008 as compared to the same period in 2007.  As a percentage of contract drilling revenue, drilling expense increased to 61% for the three-month period ended June 30, 2008 from 57% for the same period in 2007 due primarily to a decrease in dayrates for the six months ended June 30, 2008 as compared to the same period in 2007.
 
     Well Service Expense. Well service expense increased $5.1 million to $11.0 million for the six months ended June 30, 2008 from $5.9 million for the same period in 2007.  This 86% increase is primarily due to the increase in revenue hours and the average number of operating workover rigs in our fleet for the six months ended June 30, 2008 as compared to the same period in 2007.
 
     Depreciation Expense.  Depreciation expense increased $2.3 million to $24.4 million for the six months ended June 30, 2008 from $22.1 million for the same period in 2007. The increase is primarily due to the 4% increase in fixed assets.
 
     General and Administrative Expense . General and administrative expense increased $1.1 million to $11.2 million for the six months ended June 30, 2008 from $10.1 million for the same period in 2007. The increase is the result of an increase in payroll costs of $1.1 million, an increase in stock compensation expense of $915,000, and an increase in professional fees expense of $304,000  The increase in payroll costs is primarily due to our increased administrative employee count and related wage increases.  The increase in stock compensation expense is attributed to grants of restricted stock during 2007 and the six months ended June 30, 2008.  The increase in professional fees is due to services provided related to the Challenger transaction and merger agreement.  These increases were partially offset by a decrease in accounts receivable write offs of $1.2 million and a decrease in yard expense of $332,000.
 
     Interest Expense . Interest expense increased $324,000 to $2.4 million for the six months ended June 30, 2008 from $2.1 million for the same period in 2007. The increase is due to a decrease in the capitalization of interest related to our rig refurbishment program and a higher outstanding balance on our revolving credit facility partially offset by a decrease in the average interest rate on our revolving credit facility. We capitalized $459,000 of interest for the six months ended June 30, 2008 as compared to $903,000 for the same period in 2007.
 
     Income Tax Expense.  We recorded a tax expense of $7.2 million for the six months ended June 30, 2008 all of which was deferred tax expense. This compares to a deferred tax expense of $12.5 million for the six months ended June 30, 2007. This decrease is due to the decrease in pre-tax income.

Liquidity and Capital Resources
 
     Operating Activities .  Net cash provided by operating activities was $38.3 million for the six months ended June 30, 2008 as compared to $32.9 million in 2007. The increase of $5.4 million from 2007 to 2008 was primarily due to an increase in cash receipts from customers, partially offset by higher cash payments to suppliers.
 
     Investing Activities .  We use a significant portion of our cash flows from operations and financing activities for acquisitions and the refurbishment of our rigs. Cash used in investing activities was $43.0 million for the six months ended June 30, 2008 as compared to $31.7 million for the same period in 2007.   For the six months ended June 30, 2008, we used $41.0 million to purchase fixed assets and $5.1 million to purchase an equity interest in Challenger.  These amounts were partially offset by $3.0 million of proceeds received from the sale of assets.  For the six months ended June 30, 2007, we used $ 31.8 million to purchase fixed assets and $2.3 million to purchase Eagle Well Service, Inc, or Well Services.  These amounts were partially offset by $2.4 million of proceeds received from the sale of assets.
 
     Financing Activities .  Our cash flows provided by financing activities were $8.8 million for the six months ended June 30, 2008 as compared to $7.0 million used in financing activities for the same period in 2007. For the six months ended June 30, 2008, our net cash provided by financing activities related to borrowings of $10.0 million under our credit facility with Fortis Capital Corp. and borrowings of $846,000 from various lenders, partially offset by principal payments of $2.0 million to various lenders.  Our net cash used in 2007 for financing activities related to principal payments of $19.0 million under our credit agreement with Fortis Capital Corp., partially offset by borrowings of $12.0 million under our credit facility with Fortis Capital Corp.
 
     Sources of Liquidity .  Our primary sources of liquidity are cash from operations and debt and equity financing.
 
     Debt Financing .   On January 13, 2006, we entered into a $150.0 million revolving credit facility with Fortis Capital Corp., as administrative agent, lead arranger and sole bookrunner, and a syndicate of lenders, which include The Royal Bank of Scotland plc, The CIT Group/Business Credit, Inc., Calyon Corporate and Investment Bank, Merrill Lynch Capital, Comerica Bank and Caterpillar Financial Services Corporation. The revolving credit facility matures on January 13, 2009. The Company intends to refinance the revolving credit facility during 2008.  The initial aggregate revolving commitment of $150.0 million is automatically and permanently reduced by $10.0 million at the end of each fiscal quarter starting September 30, 2006.  The aggregate revolving commitment was $80.0 million as of June 30, 2008.  We had $2.6 million available under the credit facility at June 30, 2008. Loans under the revolving credit facility bear interest at LIBOR plus a margin that can range from 2.0% to 3.0% or, at our option, the prime rate plus a margin that can range from 1.0% to 2.0%, depending on the ratio of our outstanding senior debt to “Adjusted EBITDA,” as defined in the credit agreement.

The revolving credit facility also provides for a quarterly commitment fee of 0.5% per annum of the unused portion of the revolving credit facility, and fees for each letter of credit issued under the facility. Commitment fees expense for the three and six months ended June 30, 2008 were $56,000 and $115,000, respectively, and for the three and six months ended June 30, 2007 were $68,000 and $149,000, respectively.  Our subsidiaries have guaranteed the loans and other obligations under the revolving credit facility. The obligations under the revolving credit facility and the related guarantees are secured by a first priority security interest in substantially all of our assets, as well as the shares of capital stock of our direct and indirect subsidiaries.

The revolving credit facility contains customary covenants for facilities of this type, including among other things, covenants that restrict our ability to make capital expenditures, incur indebtedness, incur liens, dispose of property, repay debt, pay dividends, repurchase shares and make certain acquisitions. The financial covenants are a minimum fixed charge coverage ratio of 1.75 to 1.00 and a maximum total leverage ratio of 2.00 to 1.00. We were in compliance with all covenants at June 30, 2008.  The revolving credit facility provides for mandatory prepayments under certain circumstances. The revolving credit facility contains various events of default, including failure to pay principal and interest when due, breach of covenants, materially incorrect representations, default under certain other agreements, bankruptcy or insolvency, the occurrence of specified ERISA events, entry of enforceable judgments against us in excess of $3.0 million not stayed, and the occurrence of a change of control. If an event of default occurs, all commitments under the revolving credit facility may be terminated and all of our obligations under the revolving credit facility could be accelerated by the lenders, causing all loans outstanding (including accrued interest and fees payable thereunder) to be declared immediately due and payable.

We are party to term installment loans for an aggregate principal amount of approximately $4.5 million. These term loans are payable in 96 monthly installments, mature in 2013 and 2014 and have a weighted average annual interest rate of 6.92%. The proceeds from these term loans were used to purchase cranes.
 
We are party to a term loan agreement with Ameritas Life Insurance Corp. for an aggregate principal amount of approximately $1.6 million related to the acquisition of a building. This term loan is payable in 166 monthly installments, matures in 2021 and has an interest rate of 6%.
 
Issuances of Equity.
 
In connection with our acquisition of Well Services in January 2007, we issued 1,070,390 shares of our common stock.
 
Capital Expenditures.
 
     We believe that cash flow from our operations and borrowings under our revolving credit facility will be sufficient to fund our operations for at least the next 12 months.  During 2008, the Company intends to refinance its revolving credit facility that matures on January 13, 2009.  However, additional capital may be required for future acquisitions. While we would expect to fund such acquisitions with additional borrowings and the issuance of debt and equity securities, we cannot assure you that such funding will be available or, if available, that it will be on terms acceptable to us.
 
 
     We are subject to market risk exposure related to changes in interest rates on our outstanding floating rate debt. Borrowings under our revolving credit facility bear interest at a floating rate equal to LIBOR plus a margin that can range from 2.0% to 3.0% or, at our option, the prime rate plus a margin that can range from 1.0% to 2.0%, depending on the ratio of our outstanding senior debt to Adjusted EBITDA, as defined in our credit agreement with Fortis Capital Corp. An increase or decrease of 1% in the interest rate would have a corresponding decrease or increase in our net income (loss) of approximately $436,000 annually, based on the $70.0 million outstanding in the aggregate under our credit facility as of June 30, 2008.
 

Evaluation of Disclosure Control and Procedures .
 
     As of the end of the period covered by this Quarterly Report on Form 10−Q, our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a−15(e) or 15d−15(e) under the Securities Exchange Act of 1934, as amended). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of June 30, 2008 our disclosure controls and procedures are effective.
 
     Disclosure controls and procedures are controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms; and include controls and procedures designed to ensure that information is accumulated and communicated to our management, and made known to our Chief Executive Officer and Chief Financial Officer, particularly during the period when this Quarterly Report on Form 10−Q was prepared, as appropriate to allow timely decision regarding the required disclosure.

Changes in Internal Control over Financial Reporting .
 
     There were no changes in our internal control over financial reporting that occurred during the second quarter of 2008 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
 


Following the announcement of the merger agreement on January 24, 2008, three purported class action complaints were filed challenging the proposed merger between Allis-Chalmers, Bronco and Merger Sub. Two complaints were filed in Oklahoma in the District Court of Oklahoma County, the first on January 29, 2008, which we refer to as the Boothe action, and the second on February 28, 2008, which we refer to as the Goff action. The defendants named in both actions are Bronco, the Bronco board of directors and Allis-Chalmers. On April 9, 2008, the Boothe action and the Goff action were consolidated into a single action, which we refer to as the Oklahoma action. The defendants named in the Oklahoma action are Bronco, the Bronco board of directors and Allis-Chalmers. The third complaint was filed in the Delaware Court of Chancery on January 29, 2008, which we refer to as the Delaware action. The defendants named in the Delaware action are Bronco, the Bronco board of directors, Allis-Chalmers and Merger Sub.
 
The Oklahoma and Delaware actions generally allege that the proposed merger consideration is inadequate, that the Bronco board of directors breached its fiduciary duties and that Allis-Chalmers has aided and abetted the Bronco board of directors’ alleged breaches of fiduciary duties. The actions also allege that the preliminary joint proxy statement/prospectus included as part of Allis-Chalmers’ registration statement on Form S-4, filed with the SEC on February 20, 2008, contains materially incomplete and misleading information. The actions generally request, among other things, that the suits be designated class actions on behalf of the Bronco stockholders, that the proposed merger be enjoined and that the Bronco board of directors undertake an auction of Bronco or otherwise take action to maximize stockholder value. Additionally, the Delaware action requests that all allegedly misleading or omitted information be corrected in Allis-Chalmers’ preliminary joint proxy statement/prospectus. The Delaware action seeks monetary damages for Bronco’s stockholders and the Oklahoma action requests that the proposed merger be rescinded if it is consummated. All stockholders of Allis-Chalmers and Bronco are encouraged to read the complaints in their entirety to apprise themselves of the plaintiffs’ allegations, which the plaintiffs purport to make on behalf of themselves and Bronco’s other stockholders.
 
Allis-Chalmers and Bronco filed motions to dismiss the Boothe action on February 21, 2008 and February 19, 2008, respectively. In response to these motions, the parties to the Boothe action agreed to extend the time for the plaintiff to amend his complaint, and for the defendants to amend or withdraw their motions to dismiss, or file answers to the amended complaint. After the Boothe action and the Goff action were consolidated into the Oklahoma action on April 9, 2008, the plaintiffs in the Oklahoma action filed a consolidated amended complaint on April 17, 2008. Allis-Chalmers filed a motion to dismiss the amended complaint on May 14, 2008, and Bronco and the Bronco board of directors filed a motion to dismiss the amended complaint on May 19, 2008. In response to these motions, the parties to the Oklahoma action agreed to extend the time for the plaintiffs to respond to the defendants’ motions to dismiss. Under the agreement, the plaintiffs must respond by September 3, 2008. Discovery in the Oklahoma action is ongoing at this time.
 
The plaintiff in the Delaware action filed an amended complaint on April 23, 2008. The parties to the Delaware action agreed to indefinitely extend the time for the defendants to respond to the plaintiff’s amended complaint. Under the agreement, no defendant must answer the plaintiff’s amended complaint or otherwise respond until one of the following two events occurs: (1) the plaintiff files a second amended complaint, in which case the defendants will have 30 days from the date of service to answer the second amended complaint or otherwise respond; or (2) the plaintiff provides written notice to all the defendants that each defendant must answer the amended complaint, in which case each defendant will have, upon receiving the written notice, 30 days to answer the amended complaint or otherwise respond. Discovery in the Delaware action is ongoing at this time.

Allis-Chalmers, Bronco, the Bronco board of directors and Merger Sub deny the substantive allegations in the two complaints, believe the claims asserted are baseless and intend to vigorously defend these actions.  As of this time, no order has been issued in either proceeding that would preclude the consummation of the merger.  Each of Allis-Chalmers and the Company has the right to terminate the merger agreement in the event a court enjoins the consummation of the merger.

Various other claims and lawsuits, incidental to the ordinary course of business, are pending against the Company. In the opinion of management, all matters are adequately covered by insurance or, if not covered, are not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows.


There have been no material changes to the Risk Factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2007 filed with the SEC on March 17, 2008.
