CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
     Various statements contained in or incorporated by reference into this report that express a belief, expectation, or intention, or that are not statements of historical fact, are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”). These forward-looking statements include statements, projections and estimates concerning our operations, performance, business strategy, oil and natural gas reserves, drilling program capital expenditures, liquidity and capital resources, the timing and success of specific projects, outcomes and effects of litigation, claims and disputes, derivative activities and potential financing. Forward-looking statements are generally accompanied by words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “could,” “may,” “foresee,” “plan,” “goal” or other words that convey the uncertainty of future events or outcomes. Forward-looking statements are not guarantees of performance. We have based these forward-looking statements on our current expectations and assumptions about future events. These statements are based on certain assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate under the circumstances. Actual results may differ materially from those implied or expressed by the forward-looking statements. These forward-looking statements speak only as of the date of this report, or if earlier, as of the date they were made. We disclaim any obligation to update or revise these statements unless required by securities law, and we caution you not to rely on them unduly. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties relating to, among other matters, the risks discussed in our Annual Report on Form 10-K for the year ended December 31, 2009, and in this report as well as those factors summarized below:
    sustained or further declines in the prices we receive for our oil and natural gas;
    uncertainties about the estimated quantities of oil and natural gas reserves;
    risks related to the integration of the assets of Marbob Energy Corporation and affiliates (“Marbob”) and its former employees, along with other recently acquired assets, with our operations;
    drilling and operating risks;
    the adequacy of our capital resources and liquidity including, but not limited to, access to additional borrowing capacity under our credit facility;
    the effects of government regulation, permitting and other legal requirements, including new legislation or regulation of hydraulic fracturing;
    difficult and adverse conditions in the domestic and global capital and credit markets;
    risks related to the concentration of our operations in the Permian Basin of Southeast New Mexico and West Texas;
    potential financial losses or earnings reductions from our commodity price risk management program;
    shortages of oilfield equipment, services and qualified personnel and increased costs for such equipment, services and personnel;
    risks and liabilities associated with acquired properties or businesses, including the Marbob assets;
    uncertainties about our ability to successfully execute our business and financial plans and strategies;
    uncertainties about our ability to replace reserves and economically develop our current reserves;
    general economic and business conditions, either internationally or domestically or in the jurisdictions in which we operate;
    competition in the oil and natural gas industry;
    uncertainty concerning our assumed or possible future results of operations; and
    our existing indebtedness, as well as the increase in our indebtedness as a result of the Marbob acquisition.
     Reserve engineering is a process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by our reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ from the quantities of oil and natural gas that are ultimately recovered.

Note A. Organization and nature of operations
     Concho Resources Inc. (the “Company” or “Concho”) is a Delaware corporation formed on February 22, 2006. The Company’s principal business is the acquisition, development and exploration of oil and natural gas properties in the Permian Basin region of Southeast New Mexico and West Texas.
Note B. Summary of significant accounting policies
     Principles of consolidation. The consolidated financial statements of the Company include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
     Use of estimates in the preparation of financial statements. Preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from these estimates. Depletion of oil and natural gas properties is determined using estimates of proved oil and natural gas reserves. There are numerous uncertainties inherent in the estimation of quantities of proved reserves and in the projection of future rates of production and the timing of development expenditures. Similarly, evaluations for impairment of proved and unproved oil and natural gas properties are subject to numerous uncertainties including, among others, estimates of future recoverable reserves and commodity price outlooks. Other significant estimates include, but are not limited to, asset retirement obligations, fair value of derivative financial instruments, purchase price allocations for business combinations and fair value of stock-based compensation.
     Interim financial statements. The accompanying consolidated financial statements of the Company have not been audited by the Company’s independent registered public accounting firm, except that the consolidated balance sheet at December 31, 2009 is derived from audited consolidated financial statements. In the opinion of management, the accompanying consolidated financial statements reflect all adjustments necessary to present fairly the Company’s financial position at September 30, 2010, its results of operations for the three and nine months ended September 30, 2010 and 2009 and its cash flows for the nine months ended September 30, 2010 and 2009. All such adjustments are of a normal recurring nature. In preparing the accompanying consolidated financial statements, management has made certain estimates and assumptions that affect reported amounts in the consolidated financial statements and disclosures of contingencies. Actual results may differ from those estimates. The results for interim periods are not necessarily indicative of annual results.
     Certain disclosures have been condensed or omitted from these consolidated financial statements. Accordingly, these consolidated financial statements should be read with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.
     Deferred loan costs. Deferred loan costs are stated at cost, net of amortization, which is computed using the effective interest and straight-line methods.

     Oil and natural gas sales and imbalances. Oil and natural gas revenues are recorded at the time of delivery of such products to pipelines for the account of the purchaser or at the time of physical transfer of such products to the purchaser. The Company follows the sales method of accounting for oil and natural gas sales, recognizing revenues based on the Company’s share of actual proceeds from the oil and natural gas sold to purchasers. Oil and natural gas imbalances are generated on properties for which two or more owners have the right to take production “in-kind” and, in doing so, take more or less than their respective entitled percentage. Imbalances are tracked by well, but the Company does not record any receivable from or payable to the other owners unless the imbalance has reached a level at which it exceeds the remaining reserves in the respective well. If reserves are insufficient to offset the imbalance and the Company is in an overtake position, a liability is recorded for the amount of shortfall in reserves valued at a contract price or the market price in effect at the time the imbalance is generated. If the Company is in an undertake position, a receivable is recorded for an amount that is reasonably expected to be received, not to exceed the current market value of such imbalance.
     The following tables reflect the Company’s natural gas imbalance positions at September 30, 2010 and December 31, 2009 as well as amounts reflected in oil and natural gas production expense for the three and nine months ended September 30, 2010 and 2009:

     General and administrative expense. The Company receives fees for the operation of jointly owned oil and natural gas properties and records such reimbursements as reductions of general and administrative expense. Such fees totaled approximately $3.5 million and $3.2 million for the three months ended September 30, 2010 and 2009, respectively, and $10.0 million and $8.6 million for the nine months ended September 30, 2010 and 2009, respectively.
     Recent accounting pronouncements.
     Various topics. In February 2010, the Financial Accounting Standards Board (the “FASB”) issued an update to various topics, which eliminated outdated provisions and inconsistencies in the Accounting Standards Codification (the “Codification”), and clarified certain guidance to reflect the FASB’s original intent. The update is effective for the first reporting period, including interim periods, beginning after issuance of the update, except for the amendments affecting embedded derivatives and reorganizations. In addition to amending the Codification, the FASB made corresponding changes to the legacy accounting literature to facilitate historical research. These changes are included in an appendix to the update. The Company adopted the update effective January 1, 2010, and the adoption did not have a significant impact on the Company’s consolidated financial statements.
     Accounting for extractive activities. In April 2010, the FASB issued an amendment to a paragraph in the accounting standard for oil and natural gas extractive activities accounting. The standard adds to the Codification the SEC’s Modernization of Oil and Gas Reporting release. The Company adopted the update effective April 20, 2010, and the adoption did not have a significant impact on the Company’s consolidated financial statements.
Note C. Exploratory well costs
     The Company capitalizes exploratory well costs until a determination is made that the well has either found proved reserves or that it is impaired. The capitalized exploratory well costs are presented in unproved properties in the consolidated balance sheets. If the exploratory well is determined to be impaired, the well costs are charged to expense.

Note D. Business combinations
     Wolfberry acquisitions. In December 2009, together with the acquisition of related additional interests that closed in 2010, the Company closed two acquisitions (the “Wolfberry Acquisitions”) of interests in producing and non-producing assets in the Wolfberry play in the Permian Basin for approximately $270.7 million. The Wolfberry Acquisitions were primarily funded with borrowings under the Company’s credit facility. The Company’s 2009 results of operations do not include any production, revenues or costs from the Wolfberry Acquisitions.
     The following table represents the allocation of the total purchase price of the Wolfberry Acquisitions to the acquired assets and liabilities. The allocation represents the fair values assigned to each of the assets acquired and liabilities assumed:
         
(in thousands)        
 
Fair value of the Wolfberry Acquisitions’ net assets:

Note E. Asset retirement obligations
     The Company’s asset retirement obligations represent the estimated present value of the estimated cash flows the Company will incur to plug, abandon and remediate its producing properties at the end of their productive lives, in accordance with applicable state laws. The Company does not provide for a market risk premium associated with asset retirement obligations because a reliable estimate cannot be determined. The Company has no assets that are legally restricted for purposes of settling asset retirement obligations.

Note F. Stockholders’ equity
     Equity issuance. On February 1, 2010, the Company issued 5,347,500 shares of its common stock at $42.75 per share. After deducting underwriting discounts of approximately $9.1 million and transaction costs, the Company received net proceeds of approximately $219.3 million. The net proceeds from this offering were used to repay a portion of the borrowings under the Company’s credit facility.
     Private placement of equity. On July 19, 2010, the Company entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with certain third-party accredited investors (the “Purchasers”) to sell 6,622,517 shares of its common stock at a price of $45.30 per share in a private placement (the “Private Placement”) for aggregate cash consideration of approximately $300 million. Also, the Company entered into a registration rights agreement with the investors. The Company paid approximately $7.3 million in transaction costs, which includes the placement agent fee. The common stock was issued and sold simultaneously with the closing of the acquisition of substantially all of the oil and natural gas properties and related assets owned by Marbob Energy Corporation and certain affiliated entities (collectively, “Marbob”) (the “Marbob Acquisition”) on October 7, 2010 (See Note Q). The Company used the net proceeds to finance a portion of the Marbob Acquisition.
     Treasury stock. The restrictions on certain restricted stock awards issued to certain of the Company’s officers, directors and key employees lapsed, and upon the lapse of restrictions these individuals became liable for income taxes on the value of such shares. In accordance with the Company’s 2006 Stock Incentive Plan and the applicable restricted stock award agreements, some of such persons elected to deliver shares of the Company’s common stock to the Company in exchange for cash used to satisfy such tax liability. In total, at September 30, 2010 and December 31, 2009, the Company had acquired 27,044 and 12,380 shares, respectively, that were held as treasury stock in the approximate amounts of $1.2 million and $0.4 million, respectively.
Note G. Incentive plans
     Defined contribution plan. The Company sponsors a 401(k) defined contribution plan for the benefit of substantially all employees and maintained certain other acquired plans. Currently, the Company matches 100 percent of employee contributions, not to exceed 6 percent of the employee’s annual salary. The Company contributions to the plans for the three months ended September 30, 2010 and 2009, were approximately $0.3 million and $0.3 million, respectively, and approximately $0.4 million and $0.8 million for the nine months ended September 30, 2010 and 2009, respectively.

     The Company used the simplified method that is accepted by the United States Securities and Exchange Commission (“SEC”) to calculate the expected term for stock options granted during the nine months ended September 30, 2009, since it did not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term due to the limited period of time its shares of common stock have been publicly traded. Expected volatilities are based on a combination of historical and implied volatilities of comparable companies.

     The Company uses a valuation framework based upon inputs that market participants use in pricing an asset or liability, which are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company’s own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. These two types of inputs are further prioritized into the following fair value input hierarchy:
          Level 1:   Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. The Company considers active markets to be those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
          Level 2:   Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. This category includes those derivative instruments that the Company values using observable market data. Substantially all of these inputs are observable in the marketplace throughout the full term of the derivative instrument, can be derived from observable data, or supported by observable levels at which transactions are executed in the marketplace. Level 2 instruments primarily include non-exchange traded derivatives such as over-the-counter commodity price swaps, basis swaps, investments and interest rate swaps. The Company’s valuation models are primarily industry-standard models that consider various inputs including: (i) quoted forward prices for commodities, (ii) time value and (iii) current market and contractual prices for the underlying instruments, as well as other relevant economic measures. The Company utilizes its counterparties’ valuations to assess the reasonableness of its prices and valuation techniques.
          Level 3:   Measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources (i.e., supported by little or no market activity). Level 3 instruments primarily include derivative instruments, such as commodity price collars and floors, as well as investments. The Company’s valuation models are primarily industry-standard models that consider various inputs including: (i) quoted forward prices for commodities, (ii) time value, (iii) volatility factors and (iv) current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Although the Company utilizes its counterparties’ valuations to assess the reasonableness of its prices and valuation techniques, the Company does not have sufficient corroborating market evidence to support classifying these assets and liabilities as Level 2.

     Derivative instruments. The fair value of the Company’s derivative instruments are estimated by management considering various factors, including closing exchange and over-the-counter quotations and the time value of the underlying commitments. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The following tables (i) summarize the valuation of each of the Company’s financial instruments by required pricing levels and (ii) summarize the gross fair value by the appropriate balance sheet classification, even when the derivative instruments are subject to netting arrangements and qualify for net presentation in the Company’s consolidated balance sheets at September 30, 2010 and December 31, 2009:

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
     Certain assets and liabilities are reported at fair value on a nonrecurring basis in the Company’s consolidated balance sheets. The following methods and assumptions were used to estimate the fair values:
     Impairments of long-lived assets — The Company reviews its long-lived assets to be held and used, including proved oil and natural gas properties, whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected undiscounted future net cash flows is less than the carrying amount of the assets. In that circumstance, the Company recognizes an impairment loss for the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset. The Company reviews its oil and natural gas properties by amortization base or by individual well for those wells not constituting part of an amortization base. For each property determined to be impaired, an impairment loss equal to the difference between the carrying value of the properties and the estimated fair value (discounted future cash flows) of the properties would be recognized at that time. Estimating future cash flows involves the use of judgments, including estimation of the proved and unproved oil and natural gas reserve quantities, timing of development and production, expected future commodity prices, capital expenditures and production costs.
     The Company periodically reviews its proved oil and natural gas properties that are sensitive to oil and natural gas prices for impairment. Due primarily to downward adjustments to the economically recoverable resource potential associated with declines in commodity prices and well performance, the Company recognized impairment expense related to its proved oil and natural gas properties. The following table reports the carrying amounts, estimated fair values and impairment expense of long-lived assets for the three and nine months ended September 30, 2010 and 2009:
                         
    Carrying   Estimated   Impairment

     Asset retirement obligations — The Company estimates the fair value of asset retirement obligations based on discounted cash flow projections using numerous estimates, assumptions and judgments regarding such factors as the existence of a legal obligation for an asset retirement obligation; amounts and timing of settlements; the credit-adjusted risk-free rate to be used; and inflation rates. See Note E for a summary of changes in asset retirement obligations.

Note I.   Derivative financial instruments
     The Company uses derivative financial contracts to manage exposures to commodity price and interest rate fluctuations. Commodity hedges are used to (i) reduce the effect of the volatility of price changes on the oil and natural gas the Company produces and sells, (ii) support the Company’s capital budget and expenditure plans and (iii) support the economics associated with acquisitions. Interest rate hedges are used to mitigate the cash flow risk associated with rising interest rates. The Company does not enter into derivative financial instruments for speculative or trading purposes. The Company also may enter into physical delivery contracts to effectively provide commodity price hedges. Because these contracts are not expected to be net cash settled, they are considered to be normal sales contracts and not derivatives. Therefore, these contracts are not recorded in the Company’s consolidated financial statements.
     Currently, the Company does not designate its derivative instruments to qualify for hedge accounting. Accordingly, the Company reflects changes in the fair value of its derivative instruments in its statements of operations.

     Interest rate derivative contracts. The Company has interest rate swaps which fix the LIBOR interest rate on $300 million of the Company’s bank debt at 1.90 percent for three years beginning in May 2009. For this portion of the Company’s bank debt, the all-in interest rate will be calculated by adding the fixed rate of 1.90 percent to a margin that ranges from 2.00 percent to 3.00 percent, depending on the amount of bank debt outstanding.

     Advances on the Credit Facility bear interest, at the Company’s option, based on (i) the prime rate of JPMorgan Chase Bank (“JPM Prime Rate”) (3.25 percent at September 30, 2010) or (ii) a Eurodollar rate (substantially equal to the London Interbank Offered Rate). At September 30, 2010, the interest rates of Eurodollar rate advances and JPM Prime Rate advances varied, with interest margins ranging from 200 to 300 basis points and 112.5 to 212.5 basis points, respectively, per annum depending on the debt balance outstanding. At September 30, 2010, the Company paid commitment fees on the unused portion of the available borrowing base of 50 basis points per annum.
     The Credit Facility also includes a same-day advance facility under which the Company may borrow funds from the administrative agent. Same-day advances cannot exceed $25 million and the maturity dates cannot exceed fourteen days. The interest rate on the same-day advance facility is the JPM Prime Rate plus the applicable interest margin.
     The Company’s obligations under the Credit Facility are secured by a first lien on substantially all of the Company’s oil and natural gas properties. In addition, all of the Company’s subsidiaries are guarantors and all general partner, limited partner and membership interests in the Company’s subsidiaries owned by the Company have been pledged to secure borrowings under the Credit Facility. The Credit Facility contains various restrictive covenants and compliance requirements which include (a) maintenance of certain financial ratios, including (i) a quarterly ratio of total debt to consolidated earnings before interest expense, income taxes, depletion, depreciation, and amortization, exploration expense and other noncash income and expenses to be no greater than 4.0 to 1.0, and (ii) a ratio of current assets to current liabilities, excluding noncash assets and liabilities related to financial derivatives and asset retirement obligations and including the unfunded amounts under the Credit Facility, to be no less than 1.0 to 1.0; (b) limits on the incurrence of additional indebtedness and certain types of liens; (c) restrictions as to mergers, combinations and dispositions of assets; and (d) restrictions on the payment of cash dividends. At September 30, 2010, the Company was in compliance with its covenants under the Credit Facility.
     8.625% unsecured senior notes. On September 18, 2009, the Company completed its public offering of $300 million aggregate principal amount of 8.625% senior notes due 2017 (the “Senior Notes”). The Senior Notes are fully and unconditionally guaranteed on a senior unsecured basis by all of the Company’s subsidiaries.
     The Senior Notes will mature on October 1, 2017, and interest is payable on the Senior Notes each April 1 and October 1. The Company received net proceeds of $288.2 million (net of related estimated offering costs), which were used to repay a portion of the outstanding borrowings under the Credit Facility.
     The Company may redeem some or all of the Senior Notes at any time on or after October 1, 2013 at the redemption prices specified in the indenture governing the Senior Notes. The Company may also redeem up to 35 percent of the Senior Notes using all or a portion of the net proceeds of certain public sales of equity interests completed before October 1, 2012 at a redemption price as specified in the indenture. If the Company sells certain assets or experiences specific kinds of change of control, each as described in the indenture, each holder of the Senior Notes will have the right to require the Company to repurchase the Senior Notes at a purchase price described in the indenture plus accrued and unpaid interest, if any, to the date of repurchase. At September 30, 2010, the Company was in compliance with its covenants in the indenture governing the Senior Notes.

     Indemnification. The Company has agreed to indemnify its directors and officers for claims and damages arising from certain acts or omissions taken in such capacity.
     Legal actions. The Company is a party to proceedings and claims incidental to its business. While many of these matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect to any such proceedings or claims will not have a material adverse effect on the Company’s consolidated financial position as a whole or on its liquidity, capital resources or future results of operations. The Company will continue to evaluate proceedings and claims involving the Company on a quarter-by-quarter basis and will establish and adjust any reserves as appropriate to reflect its assessment of the then current status of the matters.
     Daywork commitments. The Company periodically enters into contractual arrangements under which the Company is committed to expend funds to drill wells in the future, including agreements to secure drilling rig services, which require the Company to make future minimum payments to the rig operators. The Company records drilling commitments in the periods in which well capital is incurred or rig services are provided.

Note L. Income taxes
     The Company uses an asset and liability approach for financial accounting and reporting for income taxes. The Company’s objectives of accounting for income taxes are to recognize (i) the amount of taxes payable or refundable for the current year and (ii) deferred tax liabilities and assets for the future tax consequences of events that have been recognized in its financial statements or tax returns. The Company and its subsidiaries file a federal corporate income tax return on a consolidated basis. The tax returns and the amount of taxable income or loss are subject to examination by federal and state taxing authorities.
     The Company continually assesses both positive and negative evidence to determine whether it is more likely than not that deferred tax assets can be realized prior to their expiration. Management monitors Company-specific, oil and natural gas industry and worldwide economic factors and assesses the likelihood that the Company’s net operating loss carryforwards (“NOLs”) and other deferred tax attributes in the United States, state, and local tax jurisdictions will be utilized prior to their expiration. At September 30, 2010, the Company had no valuation allowances related to its deferred tax assets.
     At September 30, 2010, the Company did not have any significant uncertain tax positions requiring recognition in the financial statements. The tax years 2004 through 2009 remain subject to examination by the major tax jurisdictions.

(a)   The Company incurred charges for services rendered in the ordinary course of business from Chase Oil and its affiliates including a drilling contractor, an oilfield services company, a supply company, a drilling fluids supply company, a pipe and tubing supplier, a fixed base operator of aircraft services and a software company. The tables above summarize the charges incurred as well as outstanding payables and receivables.
 
(b)   The Company purchased oil and natural gas properties from third parties in which employees of the Company owned a working interest. The tables above summarize the Company’s activities with these employees. During the three and nine months ended September 30, 2010, the Company acquired oil and natural gas interests from an employee of the Company.
 
(c)   Certain persons affiliated with Chase Oil own overriding royalty interests in certain of the Company’s properties. The tables above summarize the amounts paid attributable to such interests and amounts due at period end.
 
(d)   Royalties are paid on certain properties, located in Andrews County, Texas, to a partnership of which one of the Company’s directors is the general partner and owns a 3.5 percent partnership interest. The tables above summarize the amounts paid attributable to such interest and amounts due at period end.
 
(e)   On June 30, 2009, Steven L. Beal, the Company’s then president and chief operating officer, retired from such positions. On June 9, 2009, the Company entered into a consulting agreement (the “Consulting Agreement”) with Mr. Beal, under which Mr. Beal began serving as a consultant to the Company on July 1, 2009. Either the Company or Mr. Beal may terminate the consulting relationship at any time by giving ninety days written notice to the other party; however, the Company may terminate the relationship immediately for cause. During the term of the consulting relationship, Mr. Beal will receive a consulting fee of $20,000 per month and a monthly reimbursement for his medical and dental coverage costs. If Mr. Beal dies during the term of the Consulting Agreement, his estate will receive a $60,000 lump sum payment. As part of the consulting agreement, certain of Mr. Beal’s stock-based awards were modified to permit vesting and exercise under the original terms of the stock-based awards as if Mr. Beal were still an employee of the Company while he is performing consulting services for the Company. The tables above summarize the Company’s activities pursuant to the consulting agreement with this director.
     Saltwater disposal services agreement. Among the assets the Company acquired from Chase Oil is an undivided interest in a saltwater gathering and disposal system, which is owned and maintained under a written agreement among the Company and Chase Oil and certain of its affiliates, and under which the Company as operator gathers and disposes of produced water. The system is owned jointly by the Company and Chase Oil and its affiliates in undivided ownership percentages, which are annually redetermined as of January 1 on the basis of each party’s percentage contribution of the total volume of produced water disposed of through the system during the prior calendar year. As of January 1, 2010, the Company owned 97.5 percent of the system and Chase Oil and its affiliates owned 2.5 percent.
     Purchase of residence. During the second quarter of 2010, the Company purchased the Houston, Texas residence of an officer of the Company. To effectuate the purchase, the Company engaged a third-party relocation company, who executed the purchase for

$920,000 and will subsequently sell the officer’s residence. The third-party relocation company appraised the fair value of the residence at $920,000.
Note N. Net income (loss) per share
     Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares treated as outstanding for the period.
     The computation of diluted income (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock that are dilutive to income (loss) were exercised or converted into common stock or resulted in the issuance of common stock that would then share in the earnings of the Company. These amounts include unexercised capital options, stock options and restricted stock (as issued under the Plan and described in Note G). Potentially dilutive effects are calculated using the treasury stock method.
     The following table is a reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding for the three and nine months ended September 30, 2010 and 2009:
                                 
    Three Months Ended   Nine Months Ended
    September 30,   September 30,
(in thousands)   2010   2009   2010   2009
 
Weighted average common shares outstanding:
                               
 
                               
Basic
    91,182       85,061       90,361       84,798  
Dilutive common stock options
    845       789       892        
Dilutive restricted stock
    413       238       378        
 
                               
Diluted
    92,440       86,088       91,631       84,798  
 
                               
     Because the Company reported a net loss for the nine months ended September 30, 2009, a total of 2,338,749 stock options and 477,795 restricted shares, outstanding at September 30, 2009, were not included in the diluted loss per share computations. The inclusion of these equity instruments would have been anti-dilutive; therefore, the weighted average common shares reported for basic and diluted net loss per share were the same.

     All of the Company’s wholly-owned subsidiaries have fully and unconditionally guaranteed the Senior Notes of the Company (See Note J). In accordance with practices accepted by the SEC, the Company has prepared Condensed Consolidating Financial Statements in order to quantify the assets, results of operations and cash flows of such subsidiaries as subsidiary guarantors. The following Condensed Consolidating Balance Sheets at September 30, 2010 and December 31, 2009, and Condensed Consolidating Statements of Operations for the three and nine months ended September 30, 2010 and 2009 and Condensed Consolidating Statements of Cash Flows for the nine months ended September 30, 2010 and 2009, present financial information for Concho Resources Inc. as the parent on a stand-alone basis (carrying any investments in subsidiaries under the equity method), financial information for the subsidiary guarantors on a stand-alone basis (carrying any investment in non-guarantor subsidiaries under the equity method), and the consolidation and elimination entries necessary to arrive at the information for the Company on a consolidated basis. All current and deferred income taxes are recorded on Concho Resources Inc., as the subsidiaries are flow-through entities for income tax purposes. The subsidiary guarantors are not restricted from making distributions to the Company.

Note Q. Subsequent events
     Marbob Acquisition. On July 19, 2010, the Company entered into an asset purchase agreement to acquire certain of the oil and natural gas leases, interests, properties and related assets owned by Marbob for aggregate consideration of (i) cash in the amount of $1.45 billion, (ii) the issuance by the Company to Marbob of an 8 percent unsecured promissory note due 2018 in the aggregate principal amount of $150 million and (iii) the issuance to Marbob of approximately 1.1 million shares of the Company’s common stock, subject to purchase price adjustments, which included downward purchase price adjustments based on the exercise of third parties of contractual preferential rights to purchase certain interests in properties to be acquired from Marbob.
     In October 2010, the Company closed the Marbob Acquisition. At closing, the Company paid approximately $1.1 billion in cash plus the unsecured promissory note and common stock described above for a total purchase price of approximately $1.3 billion. The total purchase price as originally announced was reduced due to third party contractual preferential rights to purchase certain of the interests in the Marbob properties. The Marbob Acquisition remains subject to certain post-closing adjustments. Certain of the third parties’ contractual preferential rights became subject to litigation, as discussed below. The Company funded the cash consideration in the Marbob Acquisition with borrowings under its Credit Facility and proceeds from the Private Placement.
     Marbob preferential rights. Certain of the Marbob interests in properties contained contractual preferential rights to purchase by third parties if Marbob were to sell them. Marbob informed the Company of its receipt of a notice from BP America Production Company (“BP”) electing to exercise its contractual preferential purchase right to purchase interests in certain of Marbob’s properties as a result of the Marbob Acquisition.
     On July 20, 2010, BP announced it was selling all its assets in the Permian Basin to a subsidiary of Apache Corporation (“Apache”). Marbob and BP owned common interests in certain properties subject to contractual preferential rights to purchase. BP and Apache contested Marbob’s ability to exercise its contractual preferential rights in this situation. As a result, Marbob and the Company filed suit against BP and Apache seeking declaratory judgment and injunctive relief to protect Marbob’s contractual right to have the option to purchase these interests in these common properties.
     On October 15, 2010, the Company and Marbob resolved the litigation with BP and Apache related to the disputed contractual preferential rights. As a result of the settlement, we acquired a non-operated interest in substantially all of the oil and natural gas assets subject to the litigation for approximately $286 million. This acquisition remains subject to certain post-closing adjustments. The Company funded the acquisition with borrowings under its Credit Facility.
     New commodity derivative contracts. In October 2010, the Company entered into the following oil price swaps to hedge additional amounts of its estimated future oil production:
                         
    Aggregate   Index   Contract
    Volume   Price(a)   Period
 
Oil (volumes in Bbls):

Price swap
    389,000     $ 86.95       1/1/12 - 11/30/12  
Price swap
    1,914,000     $ 87.58       1/1/12 - 12/31/12  
 
(a)   The index prices for the oil price swaps are based on the NYMEX-West Texas Intermediate monthly average futures price.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
     The following discussion is intended to assist in understanding our business and results of operations together with our present financial condition. This section should be read in conjunction with our historical consolidated financial statements and notes, as well as the selected historical consolidated financial data and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2009.
     During the fourth quarter of 2009, we closed the Wolfberry Acquisitions, as discussed below. The results of these acquisitions are included in our results of operations beginning January 1, 2010. As a result, many comparisons between periods will be difficult or impossible.
     Certain statements in our discussion below are forward-looking statements. These forward-looking statements involve risks and uncertainties. We caution that a number of factors could cause actual results to differ materially from these implied or expressed by the forward-looking statements. Please see “Cautionary Statement Regarding Forward-Looking Statements.”
Overview
     We are an independent oil and natural gas company engaged in the acquisition, development and exploration of producing oil and natural gas properties. Our core operations are primarily focused in the Permian Basin of Southeast New Mexico and West Texas. We have also acquired significant acreage positions in and are actively involved in the drilling or participating in drilling of emerging plays including the Bone Spring located in the Permian Basin of Southeast New Mexico and the Bakken play in the Williston Basin of North Dakota, where we are applying horizontal drilling, advanced fracture stimulation and enhanced recovery technologies. Crude oil comprised 67 percent of our 211.5 million barrels of oil equivalent (“MMBoe”) of estimated net proved reserves at December 31, 2009, and 68 percent of our 10.6 MMBoe of production for the nine months ended September 30, 2010. We seek to operate the wells in which we own an interest, and we operated wells that accounted for 95.3 percent of our proved developed producing cash flows discounted to present value at 10 percent (“PV-10”) and 66.4 percent of our 3,960 gross wells at December 31, 2009. By controlling operations, we are able to more effectively manage the cost and timing of exploration and development of our properties, including the drilling and stimulation methods used.
Commodity Prices
     Our results of operations are heavily influenced by commodity prices. Factors that may impact future commodity prices, including the price of oil and natural gas, include:
    developments generally impacting the Middle East, including Iraq and Iran;
 
    the extent to which members of the Organization of Petroleum Exporting Countries and other oil exporting nations are able to continue to manage oil supply through export quotas;
 
    the overall global demand for oil; and
 
    overall North American natural gas supply and demand fundamentals, including:
  §   the impact of any decline in the United States economy,
 
  §   weather conditions, and
 
  §   liquefied natural gas deliveries to the United States.
     Although we cannot predict the occurrence of events that may affect future commodity prices or the degree to which these prices will be affected, the prices for any commodity that we produce will generally approximate current market prices in the geographic region of the production. From time to time, we expect that we may economically hedge a portion of our commodity price risk to mitigate the impact of price volatility on our business. See Note I of the Condensed Notes to Consolidated Financial Statements included in “Item 1. Consolidated Financial Statements (Unaudited)” for additional information regarding our commodity hedge positions at September 30, 2010.

     Oil and natural gas prices have been subject to significant fluctuations during the past several years. In general, oil prices were significantly higher during the comparable periods of 2010 measured against 2009, while natural gas prices were moderately higher. The following table sets forth the average NYMEX oil and natural gas prices for the three and nine months ended September 30, 2010 and 2009, as well as the high and low NYMEX prices for the same periods:
                                 
    Three Months Ended   Nine Months Ended
    September 30,   September 30,
    2010   2009   2010   2009
 
Average NYMEX prices:

     Further, the NYMEX oil price and NYMEX natural gas price reached highs and lows of $83.90 and $79.49 per Bbl and $4.04 and $3.29 per MMBtu, respectively, during the period from October 1, 2010 to November 2, 2010. At November 2, 2010, the NYMEX oil price and NYMEX natural gas price were $83.90 per Bbl and $3.87 per MMBtu, respectively.
Recent Events
     Marbob acquisition. On July 19, 2010, we entered into an asset purchase agreement to acquire substantially all of the oil and natural gas leases, interests, properties and related assets owned by Marbob Energy Corporation and certain affiliates (“Marbob”) for aggregate consideration of (i) cash in the amount of $1.45 billion, (ii) our issuance to Marbob of an 8 percent unsecured promissory note due 2018 in the aggregate principal amount of $150 million and (iii) the issuance to Marbob of approximately 1.1 million shares of our common stock, subject to purchase price adjustments, which included downward purchase price adjustments based on the exercise of third parties of contractual preferential rights to purchase certain interests in properties to be acquired from Marbob.
     The Marbob assets are primarily located in the Permian Basin of Southeast New Mexico, including a large acreage position contiguous to our core Yeso play on the Southeast New Mexico Shelf and a significant acreage position in the emerging Bone Spring play in Southeast New Mexico. These assets are a complement to our New Mexico Shelf position and significantly increase our Yeso drilling inventory. In addition, Marbob’s Bone Spring acreage, when coupled with our existing acreage, gives us a significant acreage position in one of the newest emerging plays in the industry and adds a significant new area of potential growth to our portfolio. We also retained most of Marbob’s experienced technical and operational staff.
     In October 2010, we closed the Marbob acquisition. At closing, we paid approximately $1.1 billion in cash plus the unsecured promissory note and common stock described above for a total purchase price of approximately $1.3 billion. The total purchase price as originally announced was reduced due to third party contractual preferential rights to purchase certain of the interests in the Marbob properties. The Marbob acquisition remains subject to certain post-closing adjustments. Certain of the third parties’ contractual preferential rights became subject to litigation as discussed below. We funded the Marbob acquisition with borrowings under our credit facility and proceeds from the private placement, discussed later.
     Marbob preferential rights. Certain of the Marbob interests in properties contained contractual preferential rights to purchase by third parties if Marbob were to sell them. Marbob informed us of its receipt of a notice from BP America Production Company (“BP”) electing to exercise its contractual preferential purchase right to purchase interests in certain of Marbob’s properties as a result of the Marbob acquisition.

     On July 20, 2010, BP announced it was selling all its assets in the Permian Basin to a subsidiary of Apache Corporation (“Apache”). Marbob and BP owned common interests in certain properties subject to contractual preferential rights to purchase. BP and Apache contested Marbob’s ability to exercise its contractual preferential rights in this situation. As a result, Marbob and we filed suit against BP and Apache seeking declaratory judgment and injunctive relief to protect Marbob’s contractual right to have the option to purchase these interests in these common properties.
     On October 15, 2010, we and Marbob resolved the litigation with BP and Apache related to the disputed contractual preferential rights. As a result of the settlement, we acquired a non-operated interest in substantially all the oil and natural gas assets subject to the litigation for approximately $286 million. This acquisition remains subject to certain post-closing adjustments. We funded the acquisition with borrowings under our credit facility.
     Private placement of equity. On July 19, 2010, we entered into a common stock purchase agreement with certain third-party accredited investors to sell 6.6 million shares of our common stock at a price of $45.30 per share in a private placement for aggregate cash consideration of approximately $300 million. We paid approximately $7.3 million in transaction costs, which includes the placement agent fee. On October 7, 2010, we closed the private placement simultaneously with the closing of the Marbob acquisition.
     Credit facility amendment . On October 7, 2010, we amended our credit facility simultaneously with the closing of the Marbob acquisition to increase the borrowing base from $1.2 billion to $2.0 billion. We paid our bank group approximately $23.6 million associated with the amendment to increase the borrowing base. Pro forma at September 30, 2010, after taking into account the closing of the Marbob acquisition, the resolution of the Marbob preferential right dispute, the closing of the credit facility amendment, the private placement and estimated related transaction costs, we estimate our outstanding indebtedness under our credit facility would have been approximately $1.5 billion and our availability under our credit facility would have been approximately $470 million.
     2011 capital budget. In November 2010, we announced our 2011 capital budget of approximately $1.1 billion, which we expect can be funded substantially within our cash flow, based on current commodity prices and our expectations. As our size and financial flexibility have grown, we now take a longer-term view on spending substantially within our cash flow, and our spending during any specific period may exceed our cash flow for that period. However, our capital budget is largely discretionary, and if we experience sustained oil and natural gas prices significantly below the current levels or substantial increases in our drilling and completion costs, we may reduce our capital spending program to be substantially within our cash flow.
     Our capital budget does not include acquisitions (other than the customary purchase of leasehold acreage). The following is a summary of our 2011 capital budget:
         
    2011  
(in millions)   Budget  
 
Drilling and recompletion opportunities in our core operating area
  $ 736  
Projects operated by third parties
    68  
Emerging plays, acquisition of leasehold acreage and other property interests, geological and geophysical and other
    200  
Facilities and other capital in our core operating areas
    100  
 
     
Total
  $ 1,104  
 
     
     Equity issuance. On February 1, 2010, we issued approximately 5.3 million shares of our common stock at $42.75 per share in a public offering. After deducting underwriting discounts of approximately $9.1 million and transaction costs, we received net proceeds of approximately $219.3 million. The net proceeds from this offering were used to repay a portion of the borrowings under our credit facility.
     Wolfberry acquisitions. In December 2009, together with the acquisition of related additional interests that closed in 2010, we closed two acquisitions of interests in producing and non-producing assets in the Wolfberry play of the Permian Basin for approximately $270.7 million in cash (the “Wolfberry Acquisitions”). The Wolfberry Acquisitions were primarily funded with borrowings under our credit facility. Our 2009 results of operations do not include any production, revenues or costs from the Wolfberry Acquisitions.
     2010 capital budget. In August 2010, we announced the increase of our 2010 capital budget to $700 million. After considering additional operations on assets acquired as a result of the Marbob acquisition and the Marbob preferential right dispute, we expect

2010 capital expenditures to total approximately $760 million, which does not include the costs of acquisitions other than customary leasehold purchases of leasehold acreage. Based on current commodity prices and our expectations, we believe our 2010 planned capital expenditures, excluding the effects of acquisitions, will exceed our 2010 cash flow. As our size and financial flexibility have grown, we now take a longer-term view on spending substantially within our cash flow, and our spending during any specific period may exceed our cash flow for that period. However, our capital expenditure plan is largely discretionary, and if we experience sustained oil and natural gas prices significantly below the current levels or substantial increases in our drilling and completion costs, we may reduce our capital spending program to be substantially within our cash flow. The following is a summary of our 2010 capital budget and current 2010 planned capital expenditures:
                 
            Current 2010  
    2010     Planned Capital

Derivative Financial Instruments
     Derivative financial instrument exposure. At September 30, 2010, the fair value of our financial derivatives was a net asset of $0.6 million. All of our counterparties to these financial derivatives are a party to our credit facility and have their outstanding debt commitments and derivative exposures collateralized pursuant to our credit facility. Under the terms of our financial derivative instruments and their collateralization under our credit facility, we do not have exposure to potential “margin calls” on our financial derivative instruments. We currently have no reason to believe that our counterparties to these commodity derivative contracts are not financially viable. Our credit facility does not allow us to offset amounts we may owe a lender against amounts we may be owed related to our financial instruments with such party.

Three Months Ended September 30, 2010 Compared to Three Months Ended September 30, 2009
     Oil and natural gas revenues. Revenue from oil and natural gas operations was $240.5 million for the three months ended September 30, 2010, an increase of $87.0 million (57 percent) from $153.5 million for the three months ended September 30, 2009. This increase was primarily due to increases in realized oil and natural gas prices and increased production (i) as a result of the Wolfberry Acquisitions and (ii) due to successful drilling efforts during 2009 and 2010. Specifically the:
    average realized oil price (excluding the effects of derivative activities) was $71.90 per Bbl during the three months ended September 30, 2010, an increase of 13 percent from $63.44 per Bbl during the three months ended September 30, 2009;
 
    total oil production was 2,656 MBbl for the three months ended September 30, 2010, an increase of 744 MBbl (39 percent) from 1,912 MBbl for the three months ended September 30, 2009;
 
    average realized natural gas price (excluding the effects of derivative activities) was $6.64 per Mcf during the three months ended September 30, 2010, an increase of 19 percent from $5.60 per Mcf during the three months ended September 30, 2009; and
 
    total natural gas production was 7,460 MMcf for the three months ended September 30, 2010, an increase of 1,707 MMcf (30 percent) from 5,753 MMcf for the three months ended September 30, 2009.
     Production expenses. The following table provides the components of our total oil and natural gas production costs for the three months ended September 30, 2010 and 2009:

Total oil and natural gas production expenses
  $ 45,072     $ 11.56     $ 25,439     $ 8.86  
 
                       
     Among the cost components of production expenses, in general, we have some control over lease operating expenses and workover costs on properties we operate, but production and ad valorem taxes are directly related to commodity price changes.
     The lease operating expenses during the third quarter of 2009 include the benefit of approximately $2.3 million ($0.79 per Boe) related to an overestimate of costs in the prior periods.
     Lease operating expenses were $22.2 million ($5.70 per Boe) for the three months ended September 30, 2010, an increase of $8.6 million (64 percent) from $13.6 million ($4.73 per Boe) for the three months ended September 30, 2009. The increase in lease operating expenses was primarily due to (i) our wells successfully drilled and completed in 2009 and 2010, (ii) additional interests acquired in the Wolfberry Acquisitions in December 2009 and (iii) the benefit of the overestimate of costs in periods prior to third quarter 2009 mentioned above. The increase in lease operating expenses per Boe was in part due to the benefit of the overestimate of costs in periods prior to third quarter 2009 mentioned above, offset in part by additional production from our wells successfully drilled and completed in 2009 and 2010 where we are receiving benefits from economies of scale.
     Ad valorem taxes have increased primarily as a result of increased valuations of our Texas properties, and the increase in our number of wells primarily associated with the Wolfberry Acquisitions and 2009 and 2010 drilling activity.

     Production taxes per unit of production were $5.30 per Boe during the three months ended September 30, 2010, an increase of 42 percent from $3.72 per Boe during the three months ended September 30, 2009. The increase was related to the increase in commodity prices and our increase in oil and natural gas revenues related to increased volumes coupled with a $2.2 million ($0.56 per Boe) increase in production taxes related to prior period adjustments on one of our assets in our New Mexico Permian area. Over the same period, our per Boe prices (excluding the effects of derivatives) increased 15 percent.
     Workover expenses were approximately $0.2 million for the three months ended September 30, 2009, which were primarily related to workovers in the New Mexico Permian area performed to restore production.
     Exploration and abandonments expense. The following table provides a breakdown of our exploration and abandonments expense for the three months ended September 30, 2010 and 2009:

     During the three months ended September 30, 2009, we wrote-off additional costs associated with a prior quarter unsuccessful exploratory well in our Texas Permian area.
     For the three months ended September 30, 2010 and 2009, we recorded $3.2 million and $0.2 million, respectively, of leasehold abandonments, which were primarily related to non-core prospects in our New Mexico Permian and Texas Permian areas.
     Depreciation, depletion and amortization expense. The following table provides components of our depreciation, depletion and amortization expense for the three months ended September 30, 2010 and 2009:

     Depletion of proved oil and natural gas properties was $60.7 million ($15.58 per Boe) for the three months ended September 30, 2010, an increase of $6.9 million (13 percent) from $53.8 million ($18.75 per Boe) for the three months ended September 30, 2009. The increase in depletion expense was primarily due to capitalized costs associated with new wells that were successfully drilled and completed in 2009 and 2010 and the Wolfberry Acquisitions, and was offset in part by the increase in the oil and natural gas prices between the periods utilized to determine proved reserves. The decrease in depletion expense per Boe was primarily due to (i) the increase in the oil and natural gas prices between the periods utilized to determine proved reserves, (ii) the increase in proved reserves

from the successful 2009 and 2010 drilling of unproved properties and (iii) the increase in total proved reserves due to the new rules related to disclosures of oil and natural gas reserves issued by the United States Securities and Exchange Commission (the “SEC”).
     On December 31, 2009, we adopted the new SEC rules related to disclosures of oil and natural gas reserves. As a result of these new SEC rules, we recorded an additional 13.6 MMBoe of proved reserves in 2009. We included the additional proved reserves in our depletion computation in the fourth quarter of 2009 and first three quarters of 2010. Our third quarter of 2010 depletion expense rate was $15.58 per Boe, which is lower than past quarters in part due to these additional proved reserves. In the future, making comparisons to prior periods as it relates to our depletion rate may be difficult as a result of these new SEC rules.
     The amortization of the intangible asset is a result of the value assigned to the operating rights that we acquired in the July 2008 acquisition of Henry Petroleum LP and certain entities and individuals affiliated with Henry Petroleum LP (collectively the “Henry Entities”). The intangible asset is currently being amortized over an estimated life of approximately 25 years.
     Impairment of long-lived assets. We periodically review our long-lived assets to be held and used, including proved oil and natural gas properties accounted for under the successful efforts method of accounting. Due primarily to downward adjustments to the economically recoverable proved reserves associated with declines in commodity prices and well performance, we recognized a non-cash charge against earnings of $1.9 million during the three months ended September 30, 2010, which was primarily attributable to natural gas related properties in our New Mexico Permian area. For the three months ended September 30, 2009, we recognized a non-cash charge against earnings of $1.1 million, which was primarily attributable to a downward revision of proved reserves primarily related to a property in our New Mexico Permian area.
     General and administrative expenses. The following table provides components of our general and administrative expenses for the three months ended September 30, 2010 and 2009:

Total general and administrative expenses
  $ 15,045     $ 3.86     $ 12,715     $ 4.44  
 
                       
     General and administrative expenses were $15.0 million ($3.86 per Boe) for the three months ended September 30, 2010, an increase of $2.3 million (18 percent) from $12.7 million ($4.44 per Boe) for the three months ended September 30, 2009. The increase in general and administrative expenses was primarily due to (i) an increase in non-cash stock-based compensation for stock-based compensation awards and (ii) an increase in the number of employees and related personnel expenses to handle our increased activities, partially offset by (i) a single month of the non-recurring bonus due to the Henry Entities’ employees in the third quarter of 2010 and (ii) an increase in third-party operating fee reimbursements. The decrease in total general and administrative expenses per Boe was primarily due to increased production associated with (i) additional production from our wells successfully drilled and completed in 2009 and 2010 and (ii) additional production from our Wolfberry Acquisitions for which we added no administrative personnel.
     In connection with the Henry Entities acquisition in July 2008, we agreed to pay certain of the Henry Entities’ former employees a predetermined bonus amount, in addition to the compensation we pay these employees, at each of the first and second anniversaries of the closing of the acquisition. Since these employees earned this bonus over the two years following the acquisition and it is outside of our control, we are reflecting the cost in our general and administrative costs as non-recurring. The final payment of the Henry Entities bonuses occurred in July 2010.

     We earn reimbursements as operator of certain oil and natural gas properties in which we own interests. As such, we earned reimbursements of $3.5 million and $3.2 million during the three months ended September 30, 2010 and 2009, respectively. This reimbursement is reflected as a reduction of general and administrative expenses in the consolidated statements of operations.
     Loss on derivatives not designated as hedges. The following table sets forth the cash settlements and the non-cash mark-to-market adjustment for the derivative contracts not designated as hedges for the three months ended September 30, 2010 and 2009:

Weighted average debt balance
  $ 698,038     $ 664,633  
     In September 2009, we refinanced $300 million of our credit facility debt with 8.625 percent unsecured senior notes. The increase in our weighted average interest rate and the increase in interest expense of approximately $5.2 million was primarily due to the higher interest rate on the unsecured senior notes.
     Income tax provisions. We recorded income tax expense of $10.1 million and $21.8 million for the three months ended September 30, 2010 and 2009, respectively. The effective income tax rate for the three months ended September 30, 2010 and 2009 was 32.7 percent and 52.5 percent, respectively. At September 30, 2010 and 2009, we estimate our annual effective tax rate to be approximately 37.0 percent and 31.0 percent, respectively, (which is discussed later in this document) and at June 30, 2010 and 2009 we estimated our annual effective tax rate to be 37.4 percent and 42.1 percent, respectively. The annual effective tax rate is determined by estimating the annual permanent tax differences and the annual pre-tax book income. Our estimates involve assumptions we believe to be reasonable at the time of the estimation. The three months ended September 30, 2010 and 2009 includes approximately $1.3 million of tax benefit and $8.9 million of tax expense, respectively, associated with the effects of the change in the six months ended June 30, 2010 and 2009 and nine months ended September 30, 2010 and 2009 estimated annual effective tax rates.
     We expect to record an approximate $8 million charge to income tax expense in the fourth quarter of 2010 to increase the tax rate we have utilized to record our net deferred tax liability. This increase in tax rate is due to an increase in our overall blended statutory state income tax rate, which is a result of the assets acquired in the Marbob acquisition and the Marbob preferential right dispute being located in New Mexico where the state income tax rate is higher than in Texas.

     Oil and natural gas revenues. Revenue from oil and natural gas operations was $668.2 million for the nine months ended September 30, 2010, an increase of $301.4 million (82 percent) from $366.8 million for the nine months ended September 30, 2009. This increase was primarily due to increases in realized oil and natural gas prices and increased production (i) as a result of the Wolfberry Acquisitions and (ii) due to successful drilling efforts during 2009 and 2010. Specifically the:
    average realized oil price (excluding the effects of derivative activities) was $73.73 per Bbl during the nine months ended September 30, 2010, an increase of 39 percent from $53.00 per Bbl during the nine months ended September 30, 2009;
 
    total oil production was 7,163 MBbl for the nine months ended September 30, 2010, an increase of 1,733 MBbl (32 percent) from 5,430 MBbl for the nine months ended September 30, 2009;
 
    average realized natural gas price (excluding the effects of derivative activities) was $6.87 per Mcf during the nine months ended September 30, 2010, an increase of 40 percent from $4.90 per Mcf during the nine months ended September 30, 2009; and
 
    total natural gas production was 20,393 MMcf for the nine months ended September 30, 2010, an increase of 4,271 MMcf (26 percent) from 16,122 MMcf for the nine months ended September 30, 2009.
     Production expenses. The following table provides the components of our total oil and natural gas production costs for the nine months ended September 30, 2010 and 2009:

     Among the cost components of production expenses, in general, we have some control over lease operating expenses and workover costs on properties we operate, but production and ad valorem taxes are directly related to commodity price changes.
     Lease operating expenses were $60.9 million ($5.77 per Boe) for the nine months ended September 30, 2010, an increase of $15.1 million (33 percent) from $45.9 million ($5.65 per Boe) for the nine months ended September 30, 2009. The increase in lease operating expenses was primarily due to (i) our wells successfully drilled and completed in 2009 and 2010 and (ii) additional interests acquired in the Wolfberry Acquisitions in December 2009. The increase in lease operating expenses per Boe was primarily due to (i) our wells successfully drilled and completed in 2009 and 2010 and (ii) additional interests acquired in the Wolfberry Acquisitions in December 2009, offset in part by additional production from our wells successfully drilled and completed in 2009 and 2010 where we are receiving benefits from economies of scale.
     Ad valorem taxes have increased primarily as a result of increased valuations of our Texas properties and the increase in our number of wells primarily associated with the Wolfberry Acquisitions and 2009 and 2010 drilling activity.
     Production taxes per unit of production were $4.80 per Boe during the nine months ended September 30, 2010, an increase of 50 percent from $3.21 per Boe during the nine months ended September 30, 2009. The increase was directly related to the increase in commodity prices and our increase in oil and natural gas revenues related to increased volumes coupled with a $2.2 million ($0.21 per

Boe) increase in production taxes related to prior periods on one of our assets in our New Mexico Permian area. Over the same period, our per Boe prices (excluding the effects of derivatives) increased 40 percent.
     Workover expenses were approximately $3.2 million and $0.7 million for the nine months ended September 30, 2010 and 2009, respectively. The 2010 amounts related primarily to increased workovers during the first two quarters of 2010 in our New Mexico Permian area due to work performed to restore production, whereas the 2009 amounts related primarily to workovers in our Texas Permian area.
     Exploration and abandonments expense. The following table provides a breakdown of our exploration and abandonments expense for the nine months ended September 30, 2010 and 2009:

     Our geological and geophysical expense, which primarily consists of the costs of acquiring and processing seismic data, geophysical data and core analysis, was approximately $1.7 million and $3.2 million for the nine months ended September 30, 2010 and 2009, respectively.
     During the nine months ended September 30, 2009, we wrote-off an unsuccessful exploratory well in our Arkansas emerging play and two unsuccessful exploratory wells in our Texas Permian area.
     For the nine months ended September 30, 2010, we recorded $3.9 million of leasehold abandonments, which were primarily related to non-core prospects in our New Mexico Permian and Texas Permian areas. For the nine months ended September 30, 2009, we recorded approximately $4.6 million of leasehold abandonments, which related primarily to the write-off of four non-core prospects in our New Mexico Permian area and three non-core prospects in our Texas Permian area.
     Depreciation, depletion and amortization expense. The following table provides components of our depreciation, depletion and amortization expense for the nine months ended September 30, 2010 and 2009:

     Depletion of proved oil and natural gas properties was $166.5 million ($15.77 per Boe) for the nine months ended September 30, 2010, an increase of $11.7 million (8 percent) from $154.8 million ($19.07 per Boe) for the nine months ended September 30, 2009. The increase in depletion expense was primarily due to capitalized costs associated with new wells that were successfully drilled and completed in 2009 and 2010 and the Wolfberry Acquisitions, and was offset in part by the increase in the oil and natural gas prices between the periods utilized to determine proved reserves. The decrease in depletion expense per Boe was primarily due to (i) the

Table of Contents

increase in the oil and natural gas prices between the periods utilized to determine proved reserves, (ii) the increase in proved reserves from the successful 2009 and 2010 drilling of unproved properties and (iii) the increase in total proved reserves due to the new SEC rules related to disclosures of oil and natural gas reserves.
     On December 31, 2009, we adopted the new SEC rules related to disclosures of oil and natural gas reserves. As a result of these new SEC rules, we recorded an additional 13.6 MMBoe of proved reserves in 2009. We included the additional proved reserves in our depletion computation in the fourth quarter of 2009 and first three quarters of 2010. Our depletion expense rate for the nine months ended September 30, 2010, was $15.77 per Boe, which is lower than the same period last year in part due to these additional proved reserves. In the future, making comparisons to prior periods as it relates to our depletion rate may be difficult as a result of these new SEC rules.
     The amortization of the intangible asset is a result of the value assigned to the operating rights that we acquired in the July 2008 acquisition of Henry Petroleum LP and certain entities and individuals affiliated with the Henry Entities. The intangible asset is currently being amortized over an estimated life of approximately 25 years.
     Impairment of long-lived assets. We periodically review our long-lived assets to be held and used, including proved oil and natural gas properties accounted for under the successful efforts method of accounting. Due primarily to downward adjustments to the economically recoverable proved reserves associated with declines in commodity prices and well performance, we recognized a non-cash charge against earnings of $9.2 million during the nine months ended September 30, 2010, which was primarily attributable to natural gas related properties in our New Mexico Permian area. For the nine months ended September 30, 2009, we recognized a non-cash charge against earnings of $9.7 million, which was primarily attributable to non-core natural gas related properties in our New Mexico Permian area.
     General and administrative expenses. The following table provides components of our general and administrative expenses for the nine months ended September 30, 2010 and 2009:

     General and administrative expenses were $46.1 million ($4.37 per Boe) for the nine months ended September 30, 2010, an increase of $7.5 million (19 percent) from $38.6 million ($4.77 per Boe) for the nine months ended September 30, 2009. The increase in general and administrative expenses was primarily due to (i) an increase in non-cash stock-based compensation for stock-based compensation awards and (ii) an increase in the number of employees and related personnel expenses to handle our increased activities, partially offset by (i) a decrease in the non-recurring bonus due to the Henry Entities employees (discussed in the next paragraph) and (ii) an increase in third-party operating fee reimbursements. The decrease in total general and administrative expenses per Boe was primarily due to increased production associated with (i) additional production from our wells successfully drilled and completed in 2009 and 2010 and (ii) additional production from our Wolfberry Acquisitions for which we added no administrative personnel.
     In connection with the Henry Entities acquisition in July 2008, we agreed to pay certain of the Henry Entities’ former employees a predetermined bonus amount, in addition to the compensation we pay these employees, at each of the first and second anniversaries of the closing of the acquisition. Since these employees earned this bonus over the two years following the acquisition and it is outside of our control, we are reflecting the cost in our general and administrative costs as non-recurring. The final payment of the Henry Entities bonuses occurred in July 2010.

     We earn reimbursements as operator of certain oil and natural gas properties in which we own interests. As such, we earned reimbursements of $10.0 million and $8.6 million during the nine months ended September 30, 2010 and 2009, respectively. This reimbursement is reflected as a reduction of general and administrative expenses in the consolidated statements of operations.
     (Gain) loss on derivatives not designated as hedges. The following table sets forth the cash settlements and the non-cash mark-to-market adjustment for the derivative contracts not designated as hedges for the nine months ended September 30, 2010 and 2009:

     Interest expense. The following table sets forth interest expense, weighted average interest rates and weighted average debt balances for the nine months ended September 30, 2010 and 2009:
                 
    Nine Months Ended
    September 30,
(dollars in thousands)   2010   2009
 
Interest expense
  $ 34,293     $ 17,379  
 
Weighted average interest rate
    5.4 %     2.7 %
 
Weighted average debt balance
  $ 690,797     $ 666,864  
     In September 2009, we refinanced $300 million of our credit facility debt with 8.625 percent unsecured senior notes. The increase in our weighted average interest rate and the increase in interest expense of approximately $16.9 million was primarily due to the higher interest rate on the unsecured senior notes. The increase in the weighted average debt balance during the nine months ended September 30, 2010 is due, in part, to our borrowings under our credit facility to finance the Wolfberry Acquisitions, offset by a partial repayment on our credit facility in February 2010 with the net proceeds of our equity offering.
     Income tax provisions. We recorded income tax expense of $124.8 million and an income tax benefit of $12.0 million for the nine months ended September 30, 2010 and 2009, respectively. The effective income tax rate for the nine months ended September 30, 2010 and 2009 was 37.0 percent and 31.0 percent, respectively. The lower annual effective tax rate in 2009 compared to 2010 is primarily due to the estimated annual 2010 and 2009 permanent tax differences compared to the related current estimated annual pre-tax book income. The estimated annual effective tax rate for 2010 and 2009 at June 30, 2010 and 2009 was 37.0 percent and 42.1 percent, respectively, based on the then estimated 2010 and 2009 annual permanent tax differences and pre-tax book income. Depending on the levels of estimated permanent differences and annual pre-tax book income and changes in those amounts between quarters can significantly alter our estimated effective tax rates between periods.
     We expect to record an approximate $8 million charge to income tax expense in the fourth quarter of 2010 to increase the tax rate we have utilized to record our net deferred tax liability. This increase in tax rate is due to an increase in our overall blended statutory state income tax rate, which is a result of the assets acquired in the Marbob acquisition and the Marbob preferential right dispute being located in New Mexico where the state income tax rate is higher than in Texas.

Capital Commitments, Capital Resources and Liquidity
     Capital commitments. Our primary needs for cash are development, exploration and acquisition of oil and natural gas assets, payment of contractual obligations and working capital obligations. Funding for these cash needs may be provided by any combination of internally-generated cash flow, financing under our credit facility, proceeds from the disposition of assets or alternative financing sources, as discussed in “Capital resources” below.
     Oil and natural gas properties. Our costs incurred on oil and natural gas properties, excluding acquisitions and asset retirement obligations, during the nine months ended September 30, 2010 and 2009 totaled $471.5 million and $293.1 million, respectively, as compared to the comparable amount in cash flows used by investing activities of $486.9 million and $316.8 million for the respective periods. The primary reason for the differences in the costs incurred and cash flow expenditures is the timing of payments. These expenditures in 2010 were significantly funded by cash flow from operations (including effects of cash settlements received from (paid on) derivatives not designated as hedges) and to a lesser extent from borrowing under our credit facility.
     In August 2010, we announced an increase of our 2010 capital budget to $700 million. At the present, we expect our 2010 planned capital expenditures to be approximately $760 million, which excludes acquisitions (other than the customary purchase of leasehold acreage) and includes approximately $57 million of capital expenditures planned for the fourth quarter of 2010 on the properties acquired in the Marbob acquisition and the Marbob preferential right dispute. Based on current commodity prices and our expectations, we believe our 2010 planned capital expenditures will exceed our 2010 cash flow. Originally, our capital budget was front-end loaded, and we expected to outspend our cash flow in the first half of 2010. We outspent our after-tax operating cash flow during the nine months ended September 30, 2010 by over $65 million, excluding acquisitions. As our size and financial flexibility have grown, we now take a longer-term view on spending substantially within our cash flow, and our spending during any specific period may exceed our cash flow for that period. However, our capital budget is largely discretionary, and if we experience sustained oil and natural gas prices significantly below the current levels or substantial increases in our drilling and completion costs, we may reduce our capital spending program to be substantially within our cash flow.
     In October 2010, we closed the Marbob acquisition and settled our Marbob preferential right dispute. For additional information see “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Recent events.”
     In October 2010, we announced our plans to divest certain Permian Basin assets which are generally not in our core areas and which have higher per unit lifting costs than our average portfolio of assets. Our current expectation is that if we are able to successfully divest of these assets, the proceeds from this divesture would be over $100 million and that we would close before the end of 2010.
     In November 2010, we announced our 2011 capital budget of approximately $1.1 billion, which we expect can be funded substantially within our cash flow, based on current commodity prices and our expectations. As our size and financial flexibility have grown, we now take a longer-term view on spending substantially within our cash flow, and our spending during any specific period may exceed our cash flow for that period. However, our capital budget is largely discretionary, and if we experience sustained oil and natural gas prices significantly below the current levels or substantial increases in our drilling and completion costs, we may reduce our capital spending program to be substantially within our cash flow.
     Other than the purchase of leasehold acreage, our current 2010 capital expenditure plan and 2011 capital budget is exclusive of acquisitions. We do not have a specific acquisition budget, since the timing and size of acquisitions are difficult to forecast. We evaluate opportunities to purchase or sell oil and natural gas properties in the marketplace and could participate as a buyer or seller of properties at various times. We seek to acquire oil and natural gas properties that provide opportunities for the addition of reserves and production through a combination of development, high-potential exploration and control of operations that will allow us to apply our operating expertise.
     Although we cannot provide any assurance, we generally attempt to fund our non-acquisition expenditures with our available cash and cash flow as adjusted from time to time; however, we may also use our credit facility, or other alternative financing sources, to fund such expenditures. The actual amount and timing of our expenditures may differ materially from our estimates as a result of, among other things, actual drilling results, the timing of expenditures by third parties on projects that we do not operate, the availability of drilling rigs and other services and equipment, regulatory, technological and competitive developments and market conditions. In addition, under certain circumstances we would consider increasing or reallocating our capital spending plans.
     Acquisitions. Our expenditures for acquisitions of proved and unproved properties (which includes customary leasehold acreage acquisitions) during the three months ended September 30, 2010 and 2009 totaled approximately $14.6 million and $7.2 million, respectively, and approximately $49.4 million and $10.7 million during the nine months ended September 30, 2010 and 2009,

55


Table of Contents

respectively. The acquisitions of proved properties during the nine months ended September 30, 2010, primarily relate to additional interests that we closed in 2010 on the Wolfberry Acquisitions and the acquisition of other Wolfberry assets.
     Contractual obligations. Our contractual obligations include long-term debt, cash interest expense on debt, operating lease obligations, drilling commitments, employment agreements with executive officers, contractual bonus payments, derivative liabilities and other obligations. Since December 31, 2009, the material changes in our contractual obligations included a $157.5 million decrease in outstanding long-term borrowings, a $23.4 million decrease in cash interest expense on debt and our net commodity derivative is now in an asset position of approximately $0.6 million. However, subsequent to September 30, 2010, our debt substantially increased as a result of the closing of the Marbob acquisition and the Marbob preferential right dispute. See Note J of Condensed Notes to Consolidated Financial Statements included in “Item 1. Consolidated Financial Statements (Unaudited)” for additional information regarding our long-term debt and “Item 3. Quantitative and Qualitative Disclosures About Market Risk” for information regarding the interest on our long-term debt and information on changes in the fair value of our open derivative obligations during the nine months ended September 30, 2010.
     Off-balance sheet arrangements. Currently, we do not have any material off-balance sheet arrangements.
     Capital resources. Our primary sources of liquidity have been cash flows generated from operating activities (including the cash settlements received from (paid on) derivatives not designated as hedges presented in our investing activities) and financing provided by our credit facility. We believe that our cash flows may not be adequate to meet both our short-term working capital requirements and our current 2010 capital expenditure plans (excluding the Marbob acquisition and the Marbob preferential right dispute). We believe we have adequate availability under our credit facility to fund cash flow deficits, though we could reduce our capital spending program to remain substantially within our cash flow.
     Cash flow from operating activities. Our net cash provided by operating activities was $402.8 million and $232.1 million for the nine months ended September 30, 2010 and 2009, respectively. The increase in operating cash flows during the nine months ended September 30, 2010 over the same period in 2009 was principally due to increases in average realized oil and natural gas prices coupled with increased production.
     Cash flow used in investing activities. During the nine months ended September 30, 2010 and 2009, we invested $504.6 million and $316.8 million, respectively, for additions to, and acquisitions of, oil and natural gas properties, inclusive of dry hole costs. Cash flows used in investing activities were higher during the nine months ended September 30, 2010 over 2009, due to the Wolfberry Acquisitions and an increase in our capital expenditures on oil and natural gas properties, offset by settlements paid on derivatives not designated as hedges during the nine months ended September 30, 2010 as compared to receipts on derivatives not designated as hedges in the comparable period in 2009.
     Cash flow from financing activities. Net cash provided by financing activities was $107.2 million and $7.7 million for the nine months ended September 30, 2010 and 2009, respectively. During the nine months ended September 30, 2010, we reduced our outstanding balance on our credit facility by $157.5 million primarily using proceeds from the issuance of common stock. During the nine months ended September 30, 2009, we had net borrowings of $15.7 million under our credit facility.
     Our credit facility, as amended, has a maturity date of July 31, 2013. At September 30, 2010, we had letters of credit outstanding under the credit facility of approximately $25,000, and our availability to borrow additional funds was approximately $807.5 million based on the borrowing base of $1.2 billion. On October 7, 2010, in connection with the closing of the Marbob acquisition, we entered into an amendment to our credit facility to increase the borrowing base from $1.2 billion to $2.0 billion, as further discussed below. The next scheduled borrowing base redetermination will be in April 2011. Between scheduled borrowing base redeterminations, we and, if requested by 66 2/3 percent of the lenders, the lenders, may each request one special redetermination.
     Advances on the credit facility bear interest, at our option, based on (i) the prime rate of JPMorgan Chase Bank (“JPM Prime Rate”) (3.25 percent at September 30, 2010) or (ii) a Eurodollar rate (substantially equal to the London Interbank Offered Rate). At September 30, 2010, the interest rates of Eurodollar rate advances and JPM Prime Rate advances varied, with interest margins ranging from 200 to 300 basis points and 112.5 to 212.5 basis points, respectively, per annum depending on the debt balance outstanding. At September 30, 2010, we paid commitment fees on the unused portion of the available borrowing base of 50 basis points per annum.
     On July 19, 2010, we entered into a common stock purchase agreement with certain third-party accredited investors to sell 6.6 million shares of our common stock at a price of $45.30 per share in a private placement for aggregate cash consideration of approximately $300 million. We paid approximately $7.3 million of transaction costs, including a placement agent fee. On October 7, 2010, we closed the private placement simultaneously with the closing of the Marbob acquisition.

56


Table of Contents

     On October 7, 2010, we amended our credit facility simultaneously with the closing of the Marbob acquisition to increase the borrowing base from $1.2 billion to $2.0 billion. We paid our bank group, now a total of 34 banks, approximately $23.6 million associated with the amendment and for the previous commitments to increase the borrowing base. Pro forma at September 30, 2010, after taking into account the closing of the Marbob acquisition, the resolution of the Marbob preferential right dispute, the closing of the credit facility amendment, the private placement and estimated related transaction costs, we estimate our outstanding indebtedness under our credit facility would have been approximately $1.5 billion and our availability under our credit facility would have been approximately $470 million.
     In conducting our business, we may utilize various financing sources, including the issuance of (i) fixed and floating rate debt, (ii) convertible securities, (iii) preferred stock, (iv) common stock and (v) other securities. We may also sell assets and issue securities in exchange for oil and natural gas assets or interests in oil and natural gas companies. Additional securities may be of a class senior to common stock with respect to such matters as dividends and liquidation rights and may also have other rights and preferences as determined from time to time by our board of directors. Utilization of some of these financing sources may require approval from the lenders under our credit facility.
     On February 1, 2010, we issued approximately 5.3 million shares of our common stock at $42.75 per share in a public offering. After deducting underwriting discounts of approximately $9.1 million and transaction costs, we received net proceeds of approximately $219.3 million. The net proceeds from this offering were used to repay a portion of the borrowing under our credit facility.
     Financial markets. The current state of the financial markets remains uncertain; however, we have recently seen improvements in the stock market, and the credit markets appear to have stabilized. There have been financial institutions that have (i) failed and been forced into government receivership, (ii) received government bail-outs, (iii) declared bankruptcy, (iv) been forced to seek additional capital and liquidity to maintain viability or (v) merged. The United States and world economies have experienced and continue to experience volatility, which continues to impact the financial markets.
     At September 30, 2010, we had $807.5 million of available borrowing capacity. Pro forma at September 30, 2010, after taking into account the closing of the Marbob acquisition, the resolution of the Marbob preferential right dispute, the closing of the credit facility amendment, the private placement and estimated related transaction costs, we estimate our outstanding indebtedness under our credit facility would have been approximately $1.5 billion and our availability under our credit facility would have been approximately $470 million. Our credit facility is backed by a large syndicate of banks. Even in light of the volatility in the financial markets, we believe that the lenders under our credit facility have the ability to fund additional borrowings we may need for our business.
     We pay floating rate interest under our credit facility, and we are unable to predict, especially in light of the uncertainty in the financial markets, whether we will incur increased interest costs due to rising interest rates. We have used interest rate derivatives to mitigate the cost of rising interest rates, and we may enter into additional interest rate derivatives in the future. Additionally, we may issue additional fixed rate debt in the future to increase available borrowing capacity under our credit facility, to extend the maturity of some of our indebtedness or to reduce our exposure to the volatility of interest rates.
     In the current financial markets, there is no assurance that we could refinance our credit facility with comparable terms. Because our credit facility matures in July 2013, we do not expect to seek refinancing of our credit facility any earlier than 2011.
     To the extent we need additional funds beyond those available under our credit facility to operate our business or make acquisitions, we would have to pursue other financing sources. These sources could include issuance of (i) fixed and floating rate debt, (ii) convertible securities, (iii) preferred stock, (iv) common stock or (v) other securities. We may also sell assets. However, in light of the current financial market conditions there are no assurances that we could obtain additional funding, or if available, at what cost and terms.
     Liquidity. Our principal sources of short-term liquidity are cash on hand and available borrowing capacity under our credit facility. At September 30, 2010, we had $0.4 million of cash on hand.
     At September 30, 2010, we had $807.5 million of available borrowing capacity. Pro forma at September 30, 2010, after taking into account the closing of the Marbob acquisition, the resolution of the Marbob preferential right dispute, the private placement and estimated related transaction costs, our outstanding indebtedness under our credit facility would have been approximately $1.5 billion and availability under our credit facility would have been approximately $471 million. Our borrowing base is redetermined semi-annually. The next scheduled borrowing base redetermination will be in April 2011. Between scheduled borrowing base redeterminations, we and, if requested by 66 2/3 percent of the lenders, the lenders, may each request one special redetermination. In general, redeterminations are based upon a number of factors, including commodity prices and reserve levels. Upon a redetermination, our

57


Table of Contents

borrowing base could be substantially reduced. In light of the current volatility in commodity prices and the state of the financial markets, there is no assurance that our borrowing base will not be reduced.
     Book capitalization and current ratio. Our book capitalization at September 30, 2010 was $2.5 billion, consisting of debt of $688.6 million and stockholders’ equity of $1.8 billion. Our debt to book capitalization was 28 percent and 39 percent at September 30, 2010 and December 31, 2009, respectively. Our ratio of current assets to current liabilities was 0.69 to 1.0 at September 30, 2010 as compared to 0.64 to 1.0 at December 31, 2009.
     At September 30, 2010, after taking into account the closing of the Marbob acquisition and the Marbob preferential right dispute, the closing of the amendment to the credit facility, the private placement and estimated related transaction costs, we estimate our debt to book capitalization to be approximately 48 percent.
     Inflation and changes in prices. Our revenues, the value of our assets, and our ability to obtain bank financing or additional capital on attractive terms have been and will continue to be affected by changes in commodity prices and the costs to produce our reserves. Commodity prices are subject to significant fluctuations that are beyond our ability to control or predict. During the nine months ended September 30, 2010, we received an average of $73.73 per barrel of oil and $6.87 per Mcf of natural gas before consideration of commodity derivative contracts compared to $53.00 per barrel of oil and $4.90 per Mcf of natural gas in the nine months ended September 30, 2009. Although certain of our costs are affected by general inflation, inflation does not normally have a significant effect on our business. In a trend that began in 2004 and continued through the first six months of 2008, commodity prices for oil and natural gas increased significantly. The higher prices led to increased activity in the industry and, consequently, rising costs. These cost trends have put pressure not only on our operating costs but also on capital costs. We expect these costs to reflect upward pressure during 2010 and 2011 as a result of the recent improvements in oil prices from 2009.

Critical Accounting Policies, Practices and Estimates
     Our historical consolidated financial statements and related notes to consolidated financial statements contain information that is pertinent to our management’s discussion and analysis of financial condition and results of operations. Preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that our management make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. However, the accounting principles used by us generally do not change our reported cash flows or liquidity. Interpretation of the existing rules must be done and judgments made on how the specifics of a given rule apply to us.
     In management’s opinion, the more significant reporting areas impacted by management’s judgments and estimates are revenue recognition, the choice of accounting method for oil and natural gas activities, oil and natural gas reserve estimation, asset retirement obligations, impairment of long-lived assets and valuation of stock-based compensation. Management’s judgments and estimates in these areas are based on information available from both internal and external sources, including engineers, geologists and historical experience in similar matters. Actual results could differ from the estimates, as additional information becomes known.
     There have been no material changes in our critical accounting policies and procedures during the nine months ended September 30, 2010. See our disclosure of critical accounting policies in the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on February 26, 2010.
Recent Accounting Pronouncements
     Various topics. In February 2010, the FASB issued an update to various topics, which eliminated outdated provisions and inconsistencies in the Accounting Standards Codification (the “Codification”), and clarified certain guidance to reflect the FASB’s original intent. The update is effective for the first reporting period, including interim periods, beginning after issuance of the update, except for the amendments affecting embedded derivatives and reorganizations. In addition to amending the Codification, the FASB made corresponding changes to the legacy accounting literature to facilitate historical research. These changes are included in an appendix to the update. We adopted the update effective January 1, 2010, and the adoption did not have a significant impact on our consolidated financial statements.
     Accounting for extractive activities. In April 2010, the FASB issued an amendment to a paragraph in the accounting standard for oil and natural gas extractive activities accounting. The standard adds to the Codification the SEC’s Modernization of Oil and Gas Reporting release. We adopted the update effective April 20, 2010, and the adoption did not have a significant impact on our consolidated financial statements.
     Accounting for leases. In August 2010, the FASB issued an Exposure Draft proposing a new approach to lease accounting so that lessors and lessees present relevant, faithfully representative information about the rights and obligations arising from leases that assists users of financial statements in their assessment of the amounts, timing and uncertainty of the cash flows arising from leases.
     The existing accounting models for leases require lessees to classify their leases as either capital leases or operating leases. However, those models have been criticized for failing to meet the needs of users of financial statements because they do not provide a faithful representation of leasing transactions. In particular, they omit relevant information about rights and obligations that meet the definitions of assets and liabilities in the boards’ conceptual framework. The models also lead to a lack of comparability and undue complexity because of the sharp ‘bright-line’ distinction between capital leases and operating leases. As a result, many users of financial statements adjust the amounts presented in the statement of financial position to reflect the assets and liabilities arising from operating leases.
     Accordingly, the FASB and the International Accounting Standards Board initiated a joint project to develop a new approach to lease accounting that would ensure that assets and liabilities arising under leases are recognized in the statement of financial position.
     Currently, we lease vehicles, equipment and office facilities under non-cancellable operating leases. If the Exposure Draft were to become a standard, we would no longer report lease payments in the consolidated statements of operations, and we would capitalize these leases on our consolidated balance sheets and depreciate them over their useful lives. We are currently evaluating the impact on our consolidated financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
     The following market risk disclosures should be read in conjunction with the quantitative and qualitative disclosures about market risk contained in our Annual Report on Form 10-K for the year ended December 31, 2009.
     We are exposed to a variety of market risks including credit risk, commodity price risk and interest rate risk. We address these risks through a program of risk management which includes the use of derivative instruments. The following quantitative and qualitative information is provided about financial instruments to which we are a party at September 30, 2010, and from which we may incur future gains or losses from changes in market interest rates or commodity prices and losses from extension of credit. We do not enter into derivative or other financial instruments for speculative or trading purposes.
     Hypothetical changes in interest rates and commodity prices chosen for the following estimated sensitivity analysis are considered to be reasonably possible near-term changes generally based on consideration of past fluctuations for each risk category. However, since it is not possible to accurately predict future changes in interest rates and commodity prices, these hypothetical changes may not necessarily be an indicator of probable future fluctuations.
     Credit risk. We monitor our risk of loss due to non-performance by counterparties of their contractual obligations. Our principal exposure to credit risk is through the sale of our oil and natural gas production, which we market to energy marketing companies and refineries and to a lesser extent our derivative counterparties. We monitor our exposure to these counterparties primarily by reviewing credit ratings, financial statements and payment history. We extend credit terms based on our evaluation of each counterparty’s creditworthiness. Although we have not generally required our counterparties to provide collateral to support their obligation to us, we may, if circumstances dictate, require collateral in the future. In this manner, we could further reduce credit risk.
     Commodity price risk. We are exposed to market risk as the prices of oil and natural gas are subject to fluctuations resulting from changes in supply and demand. To reduce our exposure to changes in the prices of oil and natural gas we have entered into, and may in the future enter into, additional commodity price risk management arrangements for a portion of our oil and natural gas production. The agreements that we have entered into generally have the effect of providing us with a fixed price for a portion of our expected future oil and natural gas production over a specified period of time. Our commodity price risk management activities could have the effect of reducing net income and the value of our common stock. An average increase in the commodity price of $10.00 per barrel of oil and $1.00 per MMBtu for natural gas from the commodity prices at September 30, 2010, would have created a net unrealized loss of approximately $165.3 million on our commodity price risk management contracts held at September 30, 2010.
     At September 30, 2010, we had (i) oil price swaps that settle on a monthly basis covering future oil production from July 1, 2010 through June 30, 2015 and (ii) a natural gas price swap, natural gas price collars and natural gas basis swaps covering future natural gas production from July 1, 2010 to December 31, 2012. See Note I of the Condensed Notes to Consolidated Financial Statements included in “Item 1. Consolidated Financial Statements (Unaudited)” for additional information on our commodity derivative contracts. The average NYMEX oil price and average NYMEX natural gas price for the nine months ended September 30, 2010, was $77.60 per Bbl and $4.54 per MMBtu, respectively. At November 2, 2010, the NYMEX oil price and NYMEX natural gas price were $83.90 per Bbl and $3.87 per MMBtu, respectively. A decrease in oil and natural gas prices would increase the fair value asset of our commodity derivative contracts from their recorded balance at September 30, 2010. Changes in the recorded fair value of the undesignated commodity derivative contracts are marked-to-market through earnings as unrealized gains or losses. The potential increase in our fair value asset would be recorded in earnings as an unrealized gain. However, an increase in the average NYMEX oil and natural gas prices above those at September 30, 2010, would result in a decrease in our fair value asset and be recorded as an unrealized loss in earnings. We are currently unable to estimate the effects on the earnings of future periods resulting from changes in the market value of our commodity derivative contracts.
     Interest rate risk. Our exposure to changes in interest rates relates primarily to debt obligations. We manage our interest rate exposure by limiting our variable-rate debt to a certain percentage of total capitalization and by monitoring the effects of market changes in interest rates. To reduce our exposure to changes in interest rates we have entered into, and may in the future enter into additional interest rate risk management arrangements for a portion of our outstanding debt. The agreements that we have entered into generally have the effect of providing us with a fixed interest rate for a portion of our variable rate debt. We may utilize interest rate derivatives to alter interest rate exposure in an attempt to reduce interest rate expense related to existing debt issues. Interest rate derivatives are used solely to modify interest rate exposure and not to modify the overall leverage of the debt portfolio. We are exposed to changes in interest rates as a result of our credit facility, and the terms of our credit facility require us to pay higher interest rate margins as we utilize a larger percentage of our available borrowing base.
     At September 30, 2010, we had interest rate swaps on $300 million of notional principal that fixed the LIBOR interest rate (not including the interest rate margins discussed above) at 1.90 percent for the three years beginning in May 2009. An average decrease

in future interest rates of 25 basis points from the future rate at September 30, 2010, would have increased our net unrealized liability on our interest rate risk management contracts by approximately $1.2 million.
     We had total indebtedness of $392.5 million outstanding under our credit facility at September 30, 2010. The impact of a 1 percent increase in interest rates on this amount of debt would result in increased annual interest expense of approximately $3.9 million.
     The fair value of our derivative instruments is determined based on our valuation models. We did not change our valuation method during 2010. During 2010, we were party to commodity and interest rate derivative instruments. See Note I of the Condensed Notes to Consolidated Financial Statements included in “Item 1. Consolidated Financial Statements (Unaudited)” for additional information regarding our derivative instruments. The following table reconciles the changes that occurred in the fair values of our derivative instruments during the nine months ended September 30, 2010:

Item 4. Controls and Procedures
     Evaluation of Disclosure Controls and Procedures. As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective at September 30, 2010 at the reasonable assurance level.
     Changes in Internal Control over Financial Reporting. There have been no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during our last fiscal quarter that have materially affected or are reasonably likely to materially affect our internal controls over financial reporting.

PART II — OTHER INFORMATION
Item 1. Legal Proceedings
     We are party to the legal proceedings that are described in Notes K and Q of the Condensed Notes to Consolidated Financial Statements included in “Item 1. Consolidated Financial Statements (Unaudited).” We are party to certain proceedings and claims incidental to our business. While many of these other matters involve inherent uncertainty, we believe that the liability, if any, ultimately incurred with respect to such other proceedings and claims will not have a material adverse effect on our consolidated financial position as a whole or on our liquidity, capital resources or future results of operations.
Item 1A. Risk Factors
     In addition to the other information set forth in this Report, you should carefully consider the risks discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, under the headings “Item 1. Business — Competition, Marketing Arrangements and Applicable Laws and Regulations,” “Item 1A. Risk Factors” and “Item 7A. Quantitative and Qualitative Disclosures About Market Risk,” which risks could materially affect the Company’s business, financial condition or future results. Except for the risk factor set forth below, there have been no material changes in the Company’s risk factors from those described in its Annual Report on Form 10-K for the year ended December 31, 2009, and “Item 1A. Risk Factors” in our Quarterly Report on Form 10-Q for the six months ended June 30, 2010.
     The risk factor below is intended to replace the risk factor in our Annual Report on Form 10-K for the year ended December 31, 2009 entitled “Our indebtedness could restrict our operations and make us more vulnerable to adverse economic conditions.”
We have substantial indebtedness and may incur substantially more debt. Higher levels of indebtedness make us more vulnerable to economic downturns and adverse developments in our business.
     We have incurred debt amounting to approximately $688.6 million as of September 30, 2010. At September 30, 2010, the borrowing base under our credit facility was $1.2 billion. At September 30, 2010, we had $807.5 million of available borrowing capacity. On October 7, 2010, in connection with the closing of the Marbob acquisition, we entered into an amendment to our credit facility to increase the borrowing base from $1.2 billion to $2.0 billion. Pro forma at September 30, 2010, after taking into account the closing of the Marbob acquisition, the resolution of the Marbob preferential right dispute, the closing of the credit facility amendment, the private placement and estimated related transaction costs, we estimate our outstanding indebtedness under our credit facility would have been approximately $1.5 billion and our availability under our credit facility would have been approximately $470 million.
     As a result of our indebtedness, we will need to use a portion of our cash flow to pay interest, which will reduce the amount we will have available to finance our operations and other business activities and could limit our flexibility in planning for or reacting to changes in our business and the industry in which we operate. Our indebtedness under our credit facility is at a variable interest rate, and so a rise in interest rates will generate greater interest expense to the extent we do not have applicable interest rate fluctuation hedges. The amount of our debt may also cause us to be more vulnerable to economic downturns and adverse developments in our business.
     We may incur substantially more debt in the future. The indentures governing our outstanding 8.625 percent unsecured senior notes due 2017 contain restrictions on our incurrence of additional indebtedness. These restrictions, however, are subject to a number of qualifications and exceptions, and under certain circumstances, we could incur substantial additional indebtedness in compliance with these restrictions. Moreover, these restrictions do not prevent us from incurring obligations that do not constitute indebtedness under the indentures.
     Our ability to meet our debt obligations and other expenses will depend on our future performance, which will be affected by financial, business, economic, regulatory and other factors, many of which we are unable to control. If our cash flow is not sufficient to service our debt, we may be required to refinance debt, sell assets or sell additional shares of common stock on terms that we may not find attractive if it may be done at all. Further, our failure to comply with the financial and other restrictive covenants relating to our indebtedness could result in a default under that indebtedness, which could adversely affect our business, financial condition and results of operations.
