NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
These consolidated financial statements have been prepared by Gulfport Energy Corporation (the “Company” or “Gulfport”) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"), and reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods, on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies, and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the summary of significant accounting policies and notes thereto included in the Company's most recent annual report on Form 10-K. Results for the three and nine month periods ended September 30, 2015 are not necessarily indicative of the results expected for the full year.

1. | ACQUISITIONS

In February 2014, the Company entered into a definitive agreement with Rhino Exploration LLC ("Rhino") to acquire additional oil and natural gas properties consisting of approximately 8,000 net acres in the Utica Shale, as well as Rhino's interest in all of the producing wells on this acreage (the "Rhino Acquisition"). The Company purchased approximately $182.0 million ($179.5 million net of purchase price adjustments) of these assets in 2014.
The Rhino Acquisition qualified as a business combination for accounting purposes and, as such, the Company estimated the fair value of the acquired properties as of the March 20, 2014 acquisition date. The fair value of the assets and liabilities acquired was estimated using assumptions that represent Level 3 inputs. See Note 11 - "Fair Value Measurements" for additional discussion of the measurement inputs.
The Company estimated that the consideration paid in the Rhino Acquisition for these properties approximated the fair value that would be paid by a typical market participant. As a result, no goodwill or bargain purchase gain was recognized in conjunction with the purchase.
The following table summarizes the consideration paid in the Rhino Acquisition to acquire the properties and the fair value amount of the assets acquired as of March 20, 2014.

In April 2015, the Company entered into an agreement to acquire Paloma Partners III, LLC ("Paloma") for a total purchase price of approximately $301.9 million, subject to certain adjustments. Paloma holds approximately 24,000 net nonproducing acres in the Utica Shale of Ohio. In accordance with the agreement, the Company deposited $75.0 million into an escrow account. At the closing of the transaction the deposit was credited toward the purchase price. This transaction closed on August 31, 2015 for a purchase price of approximately $302.3 million, net of purchase price adjustments. At closing, approximately $30.1 million of the purchase price was placed in escrow pending completion of title review after the closing.
On June 9, 2015, the Company completed the acquisition of 6,198 gross and net acres located in Belmont and Jefferson Counties, Ohio from American Energy-Utica, LLC ("AEU") for a purchase price of approximately $68.2 million, subject to

adjustment. On June 12, 2015, the Company completed the acquisition of 38,965 gross (27,228 net) acres located in Monroe County, Ohio, 14.6 MMcf per day of average net production (estimated for April 2015), 18 gross (11.3 net) drilled but uncompleted wells, an 11 mile gas gathering system and a four well pad location from AEU for a total purchase price of approximately $319.0 million (the "Monroe Acquisition"). On June 29, 2015, the Company acquired an additional 4,950 gross (1,900 net) acres in Monroe County for an additional $18.2 million from AEU. The total purchase price of these transactions, collectively referred to as the ("AEU Acquisition"), was approximately $405.4 million, subject to closing adjustments. At closing, approximately $67.1 million of the purchase price was placed in escrow pending completion of title review after the closing.
The AEU Acquisition qualified as a business combination for accounting purposes and, as such, the Company estimated the fair value of the acquired properties as of the June 12, 2015 acquisition date. The fair value of the assets and liabilities acquired was estimated using assumptions that represent Level 3 inputs. See Note 11 - "Fair Value Measurements" for additional discussion of the measurement inputs.
The Company estimated that the consideration paid in the AEU Acquisition for these properties approximated the fair value that would be paid by a typical market participant. As a result, no goodwill or bargain purchase gain was recognized in conjunction with the purchase.
The following table summarizes the consideration paid in the AEU Acquisition to acquire the properties and the fair value amount of the assets acquired as of June 12, 2015. Both the consideration paid and the fair value assigned to the assets is preliminary and subject to adjustment upon final closing.

| September 30, 2015 |  | December 31, 2014
| (In thousands)
Oil and natural gas properties | $ | 5,258,762 |  |  | $ | 3,923,154 |
Office furniture and fixtures | 12,453 |  |  | 10,752 |
Building | 11,550 |  |  | 5,398 |
Land | 3,667 |  |  | 2,194 |
Total property and equipment | 5,286,432 |  |  | 3,941,498 |
Accumulated depletion, depreciation, amortization and impairment | (1,896,413 | ) |  | (1,050,879 | )
Property and equipment, net | $ | 3,390,019 |  |  | $ | 2,890,619 |

Included in oil and natural gas properties at September 30, 2015 is the cumulative capitalization of $93.5 million in general and administrative costs incurred and capitalized to the full cost pool. General and administrative costs capitalized to the full cost pool represent management’s estimate of costs incurred directly related to exploration and development activities such as geological and other administrative costs associated with overseeing the exploration and development activities. All general and administrative costs not directly associated with exploration and development activities were charged to expense as they were incurred. Capitalized general and administrative costs were approximately $7.3 million and $20.8 million for the

three and nine months ended September 30, 2015, respectively, and $5.9 million and $19.1 million for the three and nine months ended September 30, 2014, respectively.
The following table summarizes the Company’s non-producing properties excluded from amortization by area at September 30, 2015:

| September 30, 2015

Colorado | $ | 5,088 |
Bakken | 96 |
Southern Louisiana | 342 |
Ohio | 2,013,232 |
Other | 45 |
| $ | 2,018,803 |

At December 31, 2014, approximately $1.5 billion of non-producing leasehold costs was not subject to amortization.
The Company evaluates the costs excluded from its amortization calculation at least annually. Subject to industry conditions and the level of the Company’s activities, the inclusion of most of the above referenced costs into the Company’s amortization calculation is expected to occur within three to five years.
The Company's oil and natural gas properties are subject to quarterly full cost ceiling tests. Under the ceiling test, capitalized costs, less accumulated amortization and related deferred income taxes, may not exceed an amount equal to the sum of the present value of estimated future net revenues less estimated future expenditures to be incurred in developing and producing the proved reserves based on internally prepared reserve reports, less any related income tax effects. Estimated future net revenues for the quarterly ceiling are calculated using the average of commodity prices on the first day of the month over the trailing 12-month period. At September 30, 2015, the net book value of the Company’s oil and gas properties, less related deferred income taxes, was above the calculated ceiling as a result of reduced commodity prices for the period leading up to September 30, 2015. As a result, the Company was required to record an impairment of its oil and gas properties under the full cost method of accounting in the amount of $594.8 million for the three and nine months ended September 30, 2015.
A reconciliation of the Company's asset retirement obligation for the nine months ended September 30, 2015 and 2014 is as follows:

The new loan agreement refinanced the $2.4 million outstanding under the previous building loan agreement. The new agreement matures in February 2016 and bears interest at the rate of 5.82% per annum.

The Company used the remaining net proceeds of the October Notes Offering and the net proceeds of the December Notes Offering for general corporate purposes, which included funding a portion of its 2013 capital development plan. The October Notes and the December Notes were exchanged for substantially identical notes in the same aggregate principal amount that were registered under the Securities Act in October 2013 (the "Exchange Notes").
On August 18, 2014, the Company issued an additional $300.0 million in aggregate principal amount of senior unsecured notes due 2020 (the "August Notes") to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to certain non-U.S. persons in accordance with Regulation S under the Securities Act ("the August Notes Offering"). The August Notes were issued as additional securities under the senior note indenture. The Company used a portion of the net proceeds from the August Notes Offering to repay all amounts outstanding at such time under its revolving credit facility. The Company intends to use the remaining net proceeds of the August Notes Offering for general corporate purposes, including funding a portion of its 2014 and 2015 capital development plans. The October Notes Offering, December Notes Offering and the August Notes Offering are collectively referred to as the "Notes Offerings" and the Exchange Notes, and the August Notes are collectively referred to as the "Old Notes."
In connection with the issuance of the August Notes, the Company and the subsidiary guarantors entered into a registration rights agreement with the initial purchasers on August 18, 2014, pursuant to which the Company and the subsidiary guarantors have agreed to file a registration statement with respect to an offer to exchange the August Notes for a new issue of substantially identical debt securities registered under the Securities Act. The registration statement relating to the exchange offer for the August Notes was filed on November 6, 2014, as amended on February 3, 2015, and declared effective by the SEC on February 4, 2015. The exchange offer for the August Notes was completed in March 2015.
Under the senior note indenture relating to the Old Notes, interest on the Old Notes accrues at a rate of 7.75% per annum on the outstanding principal amount from October 17, 2012, payable semi-annually on May 1 and November 1 of each year, commencing on May 1, 2013. The Old Notes are the Company's senior unsecured obligations and rank equally in the right of payment with all of the Company's other senior indebtedness and senior in right of payment to any future subordinated indebtedness. All of the Company's existing and future restricted subsidiaries that guarantee the Company's secured revolving credit facility or certain other debt guarantee the Old Notes; provided, however, that the Old Notes are not guaranteed by Grizzly Holdings, Inc. and will not be guaranteed by any of the Company's future unrestricted subsidiaries. The Company may redeem some or all of the Old Notes at any time on or after November 1, 2016, at the redemption prices listed in the senior note indenture. Prior to November 1, 2016, the Company may redeem the Old Notes at a price equal to 100% of the principal amount plus a “make-whole” premium. In addition, prior to November 1, 2015, the Company may redeem up to 35% of the aggregate principal amount of the Old Notes with the net proceeds of certain equity offerings, provided that at least 65% of the aggregate principal amount of the Old Notes initially issued remains outstanding immediately after such redemption.

The net proceeds from this equity offering (including the net proceeds from the sale of the shares of common stock to the underwriters pursuant to their option to purchase additional shares) were approximately $501.9 million after underwriting discounts and commissions and estimated offering expenses. The Company used a portion of these net proceeds, together with a portion of the net proceeds from its concurrent senior notes offering (see Note 5, "Long Term Debt"), to repay all amounts outstanding at that time under its revolving credit facility and to fund the acquisition of Paloma (see Note 1) and intends to use the remaining net proceeds from these offerings for general corporate purposes, including the funding of a portion of its 2015 capital development plans.

The net proceeds from this equity offering (including the net proceeds from the sale of the shares of common stock to the underwriters pursuant to their option to purchase additional shares) were approximately $479.8 million after underwriting discounts and commissions and estimated offering expenses. The Company used a portion of the net proceeds to fund the Monroe Acquisition (see Note 1) and intends to use the remaining funds for general corporate purposes, including the funding of a portion of its 2015 capital development plans.

Table of Contents
The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model. Expected volatilities are based on the historical volatility of the market price of Gulfport’s common stock over a period of time ending on the grant date. Based upon the historical experience of the Company, the expected term of options granted is equal to the vesting period plus one year. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The 2013 Restated Stock Incentive Plan (which amended and restated the 2005 Plan) provides that all options must have an exercise price not less than the fair value of the Company’s common stock on the date of the grant.
No stock options were issued during the nine months ended September 30, 2015 and 2014.
The Company has not declared dividends and does not intend to do so in the foreseeable future, and thus did not use a dividend yield. In each case, the actual value that will be realized, if any, depends on the future performance of the common stock and overall stock market conditions. There is no assurance that the value an optionee actually realizes will be at or near the value estimated using the Black-Scholes model.
A summary of the status of stock options and related activity for the nine months ended September 30, 2015 is presented below:

9. | COMMITMENTS AND CONTINGENCIES

Plugging and Abandonment Funds
In connection with the Company's acquisition in 1997 of the remaining 50% interest in its WCBB properties, the Company assumed the seller’s (Chevron) obligation to contribute approximately $18,000 per month through March 2004 to a plugging and abandonment trust and the obligation to plug a minimum of 20 wells per year for 20 years commencing March 11, 1997. Chevron retained a security interest in production from these properties until the Company's abandonment obligations to Chevron have been fulfilled. Beginning in 2009, the Company could access the trust for use in plugging and abandonment charges associated with the property, although it has not yet done so. As of September 30, 2015, the plugging and abandonment trust totaled approximately $3.1 million. At September 30, 2015, the Company had plugged 463 wells at WCBB since it began its plugging program in 1997, which management believes fulfills its current minimum plugging obligation.
Employment Agreements
Effective November 1, 2012, the Company entered into an employment agreement with Messrs. James Palm, Mike Liddell and Michael G. Moore, each with an initial three-year term expiring on November 1, 2015 subject to automatic one-year extensions unless terminated by either party to the agreement at least 90 days prior to the end of the then current term. These agreements provided for minimum salary and bonus levels, subject to review and potential increase by the Compensation Committee and/or the Board of Directors, as well as participation in the Company's incentive plans and other employee benefits.
Effective February 15, 2014, Gulfport's former Chief Executive Officer, James D. Palm, retired and his employment agreement with the company terminated. The Company entered into a separation agreement with Mr. Palm, under which agreement certain benefits are provided to, and obligations imposed on, Mr. Palm. As of September 30, 2015, the minimum commitment under Mr. Palm's separation agreement was approximately $0.4 million.
Mr. Liddell resigned as the Company's Chairman effective June 2013 at which date his employment agreement with Gulfport terminated. At that same time, the Company entered into a consulting agreement with Mr. Liddell. Mr. Liddell terminated his consulting agreement with the Company effective January 1, 2015.
On April 22, 2014, the Board of Directors appointed Michael G. Moore as Chief Executive Officer of the Company. The Company and Mr. Moore entered into an amended and restated employment agreement. The agreement has a three-year term commencing effective April 22, 2014. This agreement provides, among other things, for a minimum salary level, subject to review and potential increase by the Compensation Committee and/or the Board of Directors, as well as participation in the Company's incentive plans and other employee benefits.
On March 13, 2015, the Company entered into an employment agreement with Ross Kirtley, the Company's Chief Operating Officer. The agreement has a two-year term commencing effective April 22, 2014.

This agreement provides, among other things, for a minimum salary level, subject to review and potential increase by the Compensation Committee and/or the Board of Directors, as well as participation in the Company's incentive plans and other employee benefits.
Effective as of April 29, 2015, the Company amended and restated its existing employment agreement with Mr. Moore. The employment agreement, as amended and restated as of April 29, 2015, reflects the decision of the compensation committee of the Company’s board of directors to increase Mr. Moore’s annual base salary to $460,000 for 2015 and the determination by the compensation committee to continue to increase Mr. Moore’s annual base salary during 2016 and 2017 so as to achieve alignment between the 25th and 50th percentile of the Company’s peer group disclosed in the Company’s annual proxy statement. The amended and restated employment agreement also eliminated Mr. Moore’s right to receive a fixed annual grant of 40,000 shares of restricted stock. Instead, consistent with the recommendation of the Company’s compensation consultant and approved by the compensation committee, the amended and restated employment agreement provided that Mr. Moore is entitled to receive an award of restricted stock equal to 500% of his annual base salary on the same vesting schedule as previously provided in his employment agreement with respect to his equity awards.

10. | HEDGING ACTIVITIES

Oil and Natural Gas Price Hedging Activities
The Company seeks to reduce its exposure to unfavorable changes in oil and natural gas prices, which are subject to significant and often volatile fluctuation, by entering into fixed price swaps, swaptions and basis swaps. These contracts allow
21

Table of Contents
the Company to predict with greater certainty the effective oil and natural gas prices to be received for hedged production and benefit operating cash flows and earnings when market prices are less than the fixed prices provided in the contracts. However, the Company will not benefit from market prices that are higher than the fixed prices in the contracts for hedged production
The Company records all derivative contracts at fair value. All derivative contracts are marked to market each quarter end and are included in the accompanying consolidated balance sheets as derivative assets and liabilities.
During 2014 and 2015, the Company entered into fixed price swap contracts for 2014 through 2019 with five financial institutions. The Company’s fixed price swap and swaption contracts are tied to the commodity prices on Argus and NYMEX. The Company will receive the fixed price amount stated in the contract and pay to its counterparty the current market price as listed on Argus for Louisiana Light Sweet Crude for oil, the NYMEX West Texas Intermediate for oil, the NYMEX Henry Hub for natural gas and Mont Belvieu for propane. At September 30, 2015, the Company had the following fixed price swaps and swaptions in place:

| Daily Volume (Bbls/day) |  | Weighted Average Price
October 2015 - June 2016 | 2,500 |  |  | $ | 62.38 |

| Daily Volume (MMBtu/day) |  | Weighted Average Price
October 2015 | 322,500 |  |  | $ | 3.79 |

July 2017 - December 2017 | 120,000 |  |  | $ | 3.40 |
January 2018 - December 2018 | 70,000 |  |  | $ | 3.35 |
January 2019 - March 2019 | 20,000 |  |  | $ | 3.37 |

| Daily Volume (Gal/day) |  | Weighted Average Price
October 2015 - December 2016 | 42,000 |  |  | $ | 0.48 |

In addition, the Company has entered into natural gas basis swap positions, which settle on the pricing index to basis differential of MichCon to the NYMEX Henry Hub natural gas price. As of September 30, 2015, the Company's natural gas basis swap positions were as follows:

| Daily Volume (MMBtu/day) |  | Hedged Differential
October 2015 | 40,000 |  |  | $ | 0.02 |

April 2016 - December 2016 | 40,000 |  |  | $ | 0.02 |

At September 30, 2015 the fair value of derivative assets and liabilities related to the fixed price swaps, swaptions and basis swaps was as follows:
22

Table of Contents

| (In thousands)
Short-term derivative instruments - asset | $ | 116,100 |
Long-term derivative instruments - asset | $ | 51,171 |
Short-term derivative instruments - liability | $ | 2,351 |
Long-term derivative instruments - liability | $ | 3,208 |

All fixed price swaps, swaptions and basis swaps have been executed in connection with the Company's oil and natural gas price hedging program. For fixed price swaps, swaptions and basis swaps qualifying as cash flow hedges pursuant to FASB ASC 815, the realized contract price is included in oil and gas sales in the period for which the underlying production was hedged. For those contracts which are not designated as cash flow hedges changes in the fair value are classified as revenues on the Company's consolidated statements of operations.
For derivatives designated as cash flow hedges and meeting the effectiveness guidelines of FASB ASC 815, changes in fair value are recognized in accumulated other comprehensive (loss) income until the hedged item is recognized in earnings. The Company had no cash flow hedges in place for the three and nine months ended September 30, 2015 and 2014, as all fixed price swaps, swaptions and basis swaps had either been deemed ineffective at their inception or had been accounted for using the mark-to-market accounting method.
At September 30, 2015, no amounts related to fixed price swaps, swaptions or basis swaps remain in accumulated other comprehensive (loss) income.
The Company recognized a gain of $62.2 million and $58.9 million due to the change in fair value of derivative instruments for the three and nine months ended September 30, 2015, respectively, which is included in oil and condensate and gas sales in the consolidated statements of operations. The Company recognized a gain of $29.5 million and $23.0 million due to the change in fair value of derivative instruments for the three and nine months ended September 30, 2014, respectively, which is included in oil and condensate and gas sales in the consolidated statements of operations.

11. | FAIR VALUE MEASUREMENTS

The Company records certain financial and non-financial assets and liabilities on the balance sheet at fair value in accordance with FASB ASC 820, "Fair Value Measurement and Disclosures" ("FASB ASC 820"). FASB ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. The statement establishes market or observable inputs as the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs. The statement requires fair value measurements be classified and disclosed in one of the following categories:
Level 1 – Quoted prices in active markets for identical assets and liabilities.
Level 2 – Quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3 – Significant inputs to the valuation model are unobservable.
Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.
The following tables summarize the Company’s financial and non-financial liabilities by FASB ASC 820 valuation level as of September 30, 2015:

The estimated fair value of the Company’s fixed price swap, swaption and basis swap contracts were based upon forward commodity prices based on quoted market prices, adjusted for differentials. See Note 10 for further discussion of the Company's hedging activities.
The estimated fair values of proved oil and gas properties assumed in business combinations are based on a discounted cash flow model and market assumptions as to future commodity prices, projections of estimated quantities of oil and natural gas reserves, expectations for timing and amount of future development and operating costs, projections of future rates of production, expected recovery rates, and risk-adjusted discount rates. The estimated fair values of unevaluated oil and gas properties was based on geological studies, historical well performance, location and applicable mineral lease terms. Based on the unobservable nature of certain of the inputs the estimated fair value of the oil and gas properties assumed is deemed to use Level 3 inputs. See Note 1 for further discussion of the Company's acquisitions.
The Company estimates asset retirement obligations pursuant to the provisions of FASB ASC Topic 410, “Asset Retirement and Environmental Obligations” (“FASB ASC 410”). The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with oil and gas properties. Given the unobservable nature of the inputs, including plugging costs and reserve lives, the initial measurement of the asset retirement obligation liability is deemed to use Level 3 inputs. See Note 2 for further discussion of the Company’s asset retirement obligations. Asset retirement obligations incurred during the nine months ended September 30, 2015 were approximately $5.7 million.
Due to the unobservable nature of the inputs, the fair value of the Company's initial investment in Mammoth was estimated using assumptions that represent Level 3 inputs. The Company estimated the fair value of the investment as of the November 24, 2014 contribution date to be approximately $143.5 million. See Note 3 for further discussion of the Company's contribution to Mammoth.
Due to the unobservable nature of the inputs, the fair value of the Company's investment in Grizzly was estimated using assumptions that represent Level 3 inputs. The Company estimated the fair value of the investment as of September 30, 2015 to be approximately $99.5 million. See Note 3 for further discussion of the Company's investment in Grizzly.

The carrying amounts on the accompanying consolidated balance sheet for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, and current debt are carried at cost, which approximates market value due to their short-term nature. Long-term debt related to the building loan is carried at cost, which approximates market value based on the borrowing rates currently available to the Company with similar terms and maturities.
At September 30, 2015, the carrying value of the outstanding debt represented by the Notes was approximately $963.0 million, including the remaining unamortized discount of approximately $2.6 million related to the October Notes and the remaining unamortized premium of approximately $0.3 million related to the December Notes and $15.3 million related to the August Notes. Based on the quoted market price, the fair value of the Notes was determined to be approximately $914.7 million at September 30, 2015.
The fair value of the derivative instruments is computed based on the difference between the prices provided by the fixed-price contracts and forward market prices as of the specified date, as adjusted for basis differentials, and for the Company's swaptions, market implied volatilities of the underlying commodity are also evaluated. Forward market prices for oil and natural gas are dependent upon supply and demand factors in such forward market and are subject to significant volatility.

14. | RECENT ACCOUNTING PRONOUNCEMENTS

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08: Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 changes the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other material disposal transactions that do not meet the revised definition of a discontinued operation. Under the updated standard, a disposal of a component or group of components of an entity is required to be reported as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the component or group of components of the entity (1) has been disposed of by a sale, (2) has been disposed of other than by sale or (3) is classified as held for sale. The ASU is effective for annual and interim periods beginning after December 15, 2014, however, early adoption is permitted. The Company early adopted this ASU on a prospective basis beginning with the second quarter of 2014. The adoption did not have a material impact on the Company’s consolidated financial statements.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the new standard is for the recognition of revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which the company expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced revenue disclosures, provide guidance for transactions that were not previously addressed comprehensively and improve guidance for multiple-element arrangements. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those years, using either a full or a modified retrospective application approach. In July 2015, the FASB decided to defer the effective date by one year (until 2018). The Company is in the process of evaluating the impact on its consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements - Going Concern (Subtopic 205-40)." The new guidance addresses management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and in certain circumstances to provide related footnote disclosures. The standard is effective for the annual period ending after December 15, 2016 and for annual and interim periods thereafter. Early adoption is permitted. The Company does not believe that the adoption of this guidance will have a material impact on its consolidated financial statements.
In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03)." To simplify presentation of debt issuance costs, ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. ASU 2015-03 is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The Company is in the process of assessing the effects of adoption of this new guidance.
In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments." The guidance eliminates the requirement to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. Measurement period adjustments are calculated as if they were known at the acquisition date, but are recognized in the reporting period in which they are determined. Additional disclosures are required about the impact on current-period income statement line items of adjustments that would have been recognized in prior periods if prior-period information had been revised. The guidance is effective for annual periods beginning after December 15, 2015 and is to be applied prospectively to adjustments of provisional amounts that occur after the effective date. Early adoption is permitted. The Company is in the process of evaluating the impact on its consolidated financial statements.

ITEM 2. | MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section and audited consolidated financial statements and related notes included in our Annual Report on Form 10-K and with the unaudited consolidated financial statements and related notes thereto presented in this Quarterly Report on Form 10-Q.
Disclosure Regarding Forward-Looking Statements
This report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. All statements other than statements of historical facts included in this report that address activities, events or developments that we expect or anticipate will or may occur in the future, including such things as estimated future net revenues from oil and natural gas reserves and the present value thereof, future capital expenditures (including the amount and nature thereof), business strategy and measures to implement strategy, competitive strength, goals, expansion and growth of our business and operations, plans, references to future success, reference to intentions as to future matters and other such matters are forward-looking statements. 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 in the circumstances. However, whether actual results and developments will conform with our expectations and predictions is subject to a number of risks and uncertainties, general economic, market or business conditions; the opportunities (or lack thereof) that may be presented to and pursued by us; competitive actions by other oil and natural gas companies; our ability to identify, complete and integrate acquisitions of properties and businesses; changes in laws or regulations; adverse weather conditions and natural disasters such as hurricanes and other factors, including those listed in the “Risk Factors” section of our most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q or any other filings we make with the SEC, many of which are beyond our control. Consequently, all of the forward-looking statements made in this report are qualified by these cautionary statements, and we cannot assure you that the actual results or developments anticipated by us will be realized or, even if realized, that they will have the expected consequences to or effects on us, our business or operations. We have no intention, and disclaim any obligation, to update or revise any forward-looking statements, whether as a result of new information, future results or otherwise.
Overview
We are an independent oil and natural gas exploration and production company focused on the exploration, exploitation, acquisition and production of crude oil, natural gas liquids and natural gas in the United States. Our corporate strategy is to internally identify prospects, acquire lands encompassing those prospects and evaluate those prospects using subsurface geology and geophysical data and exploratory drilling. Using this strategy, we have developed an oil and natural gas portfolio of proved reserves, as well as development and exploratory drilling opportunities on high potential conventional and unconventional oil and natural gas prospects. Our principal properties are located in the Utica Shale in Eastern Ohio and along the Louisiana Gulf Coast in the West Cote Blanche Bay, or WCBB, and Hackberry fields. In addition, we have producing properties in the Niobrara Formation of Northwestern Colorado and the Bakken Formation. We also hold a significant acreage position in the Alberta oil sands in Canada through our interest in Grizzly Oil Sands ULC, or Grizzly, and an interest in an entity that operates in Southeast Asia, including the Phu Horm gas field in Thailand. Until November 2014, we held an equity interest in Diamondback Energy, Inc., or Diamondback, a NASDAQ Global Select Market listed company to which we contributed our Permian Basin oil and natural gas interests in October 2012 immediately prior to Diamondback's initial public offering, or the Diamondback IPO. At September 30, 2015, we did not own any shares of Diamondback. We seek to achieve reserve growth and increase our cash flow through our annual drilling programs.
2015 Operational Highlights

• | Net production increased 155% to 59,530 net million cubic feet of natural gas equivalent, or MMcfe, for the three months ended September 30, 2015 from 23,367 MMcfe for the three months ended September 30, 2014.

• | During the three months ended September 30, 2015, we spud 15 gross (12.6 net) wells, participated in an additional five gross (1.1 net) wells that were drilled by other operators on our Utica Shale acreage and recompleted 25 gross and net wells. Of our 15 new wells spud at September 30, 2015, 11 were in various stages of completion and four were being drilled. In addition, we turned-to-sales 16 gross (15.4 net) wells during the three months ended September 30, 2015.

• | On April 15, 2015, we entered into an agreement to acquire Paloma Partners III, LLC, or Paloma, for a total purchase price of approximately $301.9 million, subject to closing adjustments. Paloma holds approximately 24,000 net nonproducing acres in the Utica Shale of Ohio. This transaction closed on August 31, 2015.

• | On April 21, 2015, we issued 10,925,000 shares of our common stock in an underwritten public offering (which included 1,425,000 shares sold pursuant to an option to purchase additional shares of our common stock granted to and exercised by the underwriters in full). The net proceeds from the equity offering (including the net proceeds from the sale of the shares of common stock to the underwriters under their option to purchase additional shares) were approximately $501.9 million. We used a portion of these net proceeds, together with a portion of the net proceeds from our concurrent senior notes offering described below, to repay all borrowings outstanding at that time under our senior secured revolving credit facility and to fund the acquisition of Paloma and intend to use the remaining funds from this offering for general corporate purposes, including the funding of a portion of our 2015 capital development plans.

• | On April 21 2015, we issued $350.0 million in aggregate principal amount of our 6.625% senior unsecured notes due 2023, resulting in net proceeds to us of $343.6 million.

• | On June 12, 2015, we issued 11,500,000 shares of our common stock in an underwritten public offering (which included 1,500,000 shares sold pursuant to an option to purchase additional shares of our common stock granted to and exercised by the underwriters in full). The net proceeds from the equity offering (including the net proceeds from the sale of the shares of common stock to the underwriters under their option to purchase additional shares) were approximately $479.8 million. We used a portion of these net proceeds to fund the acquisition of certain acreage and other assets in the Utica Shale in Ohio from American Energy - Utica, LLC, or AEU, described below and intend to use the remaining funds for general corporate purposes, including the funding of a portion of our 2015 capital development plans.

• | As of June 8, 2015, we completed the acquisition of 6,198 gross and net acres located in Belmont and Jefferson Counties, Ohio from AEU for a purchase price of approximately $68.2 million, subject to adjustment, in a transaction we refer to as the Belmont/Jefferson acquisition. This acreage is located near or adjacent to the acreage included in our acquisition of Paloma. This newly acquired Belmont and Jefferson County acreage is undeveloped.

• | On June 12, 2015, we completed the acquisition of 38,965 gross (27,228 net) acres located in Monroe County, Ohio, which we refer to as the Monroe County Acreage, 14.6 MMcf per day of average net production (estimated for April 2015), 18 gross (11.3 net) drilled but uncompleted wells, an 11 mile gas gathering system and a four well pad location from AEU for a total purchase price of approximately $319.0 million, which we refer to as the Monroe Acquisition. We used a portion of the net proceeds from our June 2015 equity offering described above to fund the Monroe Acquisition. The Monroe County Acreage has a net revenue interest of approximately 84% and is approximately 85% held by production by a ten well per year drilling commitment. On June 29, 2015, we acquired an additional 4,950 gross (1,900 net) acres in Monroe County for an additional approximately $18.2 million from AEU.

2015 Production and Drilling Activity
During the three months ended September 30, 2015, our total net production was 732,133 barrels of oil, 48,123,538 thousand cubic feet, or Mcf, of natural gas, and 49,093,606 gallons of natural gas liquids, or NGLs, for a total of 59,530 MMcfe, as compared to 571,438 barrels of oil, 16,556,700 Mcf of natural gas and 23,672,150 gallons of NGLs, or 23,367 MMcfe, for the three months ended September 30, 2014. Our total net production averaged approximately 647.1 MMcfe per day during the three months ended September 30, 2015 as compared to 254.0 MMcfe per day during the same period in 2014. The 155% increase in production is largely the result of the continuing development of our Utica Shale acreage.
Utica Shale. As of November 1, 2015, we had acquired leasehold interests in approximately 253,000 gross (247,000 net) acres in the Utica Shale. From January 1, 2015 through November 1, 2015, we spud 41 gross (33.6 net) wells, of which eight were producing, 29 were in various stages of completion and four were still being drilled at November 1, 2015. In addition, 15 gross (4.5 net) wells were drilled by other operators on our Utica Shale acreage during the nine months ended September 30, 2015.
As of November 1, 2015, we had four rigs under contract on our Utica Shale acreage. We currently intend to spud 49 to 53 gross (39 to 41 net) wells on our Utica Shale acreage in 2015.
Aggregate net production from our Utica Shale acreage during the three months ended September 30, 2015 was approximately 57,451 MMcfe, or 624.5 MMcfe per day, 84% of which was from natural gas and 16% of which was from oil and NGLs. During October 2015, our average daily net production from the Utica Shale was approximately 687.2 MMcfe, 86% of which was from natural gas and 14% of which was from oil and NGLs. The increase in October 2015 production was a result of our drilling activity on our Utica Shale acreage.

WCBB. From January 1, 2015 through November 1, 2015, we recompleted 35 wells and spud no new wells.
Aggregate net production from the WCBB field during the three months ended September 30, 2015 was approximately 1,488 MMcfe, or an average of 16.2 MMcfe per day, 100% of which was from oil. During October 2015, our average net daily production at WCBB was approximately 15.0 MMcfe, 100% of which was from oil. The decrease in October 2015 production was a result of normal production declines.
East Hackberry Field. From January 1, 2015 through November 1, 2015, we recompleted 33 wells and spud no new wells.
Aggregate net production from the East Hackberry field during the three months ended September 30, 2015 was approximately 453 MMcfe, or an average of 4.9 MMcfe per day, 94% of which was from oil and 6% of which was from natural gas. During October 2015, our average net daily production at East Hackberry was approximately 3.1 MMcfe, 95% of which was from oil and 5% of which was from natural gas. The decrease in October 2015 production is primarily the result of normal production declines.
West Hackberry Field. From January 1, 2015 through November 1, 2015, we did not spud any wells in our West Hackberry field.
Aggregate net production from the West Hackberry field was approximately 24 MMcfe, or an average of 265.8 Mcfe per day, 100% of which was from oil. During October 2015, our average net daily production at West Hackberry was approximately 185.7 Mcfe, 100% of which was from oil.
Niobrara Formation. Effective as of April 1, 2010, we acquired leasehold interests in the Niobrara Formation in Northwestern Colorado and, as of September 30, 2015, we held leases for approximately 5,600 net acres. From January 1, 2015 through November 1, 2015, there were no wells spud on our Niobrara Formation acreage. Aggregate net production from our Niobrara Formation acreage during the three months ended September 30, 2015 was approximately 26 MMcfe, or an average of 284.1 Mcfe per day, 100% of which was from oil. During October 2015, our average net daily production from our Niobrara Formation acreage was approximately 342.2 Mcfe, 100% of which was from oil. During 2015, we currently do not anticipate drilling any wells in the Niobrara Formation.
Bakken. As of September 30, 2015, we held approximately 864 net acres in the Bakken Formation of Western North Dakota and Eastern Montana with interests in 18 wells and overriding royalty interests in certain existing and future wells. Aggregate net production from this acreage during the three months ended September 30, 2015 was approximately 87 MMcfe, or an average of 946.3 Mcfe per day, of which 88% was from oil, 11% was from natural gas and 1% was from NGLs. During October 2015, our average daily net production from our Bakken Formation acreage was approximately 482.0 Mcfe, of which 82% was from oil and 18% was from natural gas.
2015 Updates Regarding Our Equity Investments
Grizzly Oil Sands. We, through our wholly-owned subsidiary Grizzly Holdings Inc., own a 24.9% interest in Grizzly. As of September 30, 2015, Grizzly had approximately 830,000 net acres under lease in the Athabasca, Peace River and Cold Lake oil sands regions of Alberta, Canada. Grizzly has three oil sands projects in various stages of development. Grizzly commenced commercial production from its Algar Lake Phase 1 steam-assisted gravity drainage, or SAGD, oil sand project during the second quarter of 2014 and has received regulatory approval for up to 11,300 barrels per day of bitumen production. Grizzly produced approximately 900 barrels of bitumen per day at its Algar Lake SAGD project during the first quarter of 2015. In April 2015, Grizzly determined to cease bitumen production at its Algar Lake facility due to the level of commodity prices. Grizzly intends to monitor market conditions as it assesses future plans for the facility. We reviewed our investment in Grizzly at September 30, 2015 for impairment, resulting in an other than temporary impairment write down of $58.0 million. If commodity prices continue to decline, further impairment of our investment in Grizzly may result in the future. In the first quarter of 2012, Grizzly acquired the May River property comprising approximately 47,000 acres. An initial 12,000 barrel per day development application was filed with the regulatory authorities in the fourth quarter of 2013, covering the eastern portion of the May River lease. The development application continues to move through the regulatory process and is expected to be approved by early 2016. In the first quarter of 2014, a 2-D seismic program covering approximately 83 kilometers was completed to more fully define the resource over the remaining lease beyond the development application area. At the Thickwood thermal project, a development application for a 12,000 barrel per day oil sands project was filed in the fourth

quarter of 2012. Since then, the Alberta Energy Regulator, or AER, announced it is implementing a policy for future regulatory requirements for reservoir containment in shallow SAGD areas, which impacts the Thickwood application. Additional work to advance the Thickwood application will be required and is expected to be addressed once the May River development approval is received. Grizzly has also developed delineation drilling, seismic and regulatory work plans at its Cadotte, Peace River property. Grizzly has pursued a rail marketing strategy to ensure consistent and flexible access to premium markets for its production, including its Windell truck to rail terminal located near Conklin, Alberta, which commenced transloading blended bitumen production from Algar Lake on to rail cars for delivery to the US Gulf Coast markets in the second quarter of 2014.
Thailand. We own a 23.5% ownership interest in Tatex Thailand II, LLC, or Tatex II. Tatex II, a privately held entity, holds an 8.5% interest in APICO, an international oil and gas exploration company. APICO has a reserve base located in Southeast Asia through its ownership of concessions covering approximately 243,000 acres which includes the Phu Horm Field. Our investment is accounted for on the equity method. Tatex II accounts for its investment in APICO using the cost method. Hess Corporation, or Hess, operates the field with a 35% interest. Other interest owners include APICO (35% interest), PTT Exploration and Production Public Company Limited (20% interest) and ExxonMobil (10% interest). Our gross working interest (through Tatex II as a member of APICO) in the Phu Horm field is 0.7%. Since our ownership in the Phu Horm field is indirect and Tatex II's investment in APICO is accounted for by the cost method, these reserves are not included in our year-end reserve information.
We own a 17.9% ownership interest in Tatex Thailand III, LLC, or Tatex III. Tatex III previously owned a concession covering approximately 245,000 acres in Southeast Asia. In 2009, Tatex III completed a 3-D seismic survey on this concession. Between 2010 and 2013, three wells were drilled on this concession. Each of the wells lacked sufficient permeability to produce in commercial quantities. Tatex III allowed the concession to expire in January 2015.
Other Investments. In an effort to facilitate the development of our Utica Shale and other domestic acreage, we have invested in entities that can provide services that are required to support our operations. In 2013, we participated in the formation of Stingray Energy Services LLC, or Stingray Energy, with an initial ownership interest of 50%. Stingray Energy provides rental tools for land-based oil and natural gas drilling, completion and workover activities as well as the transfer of fresh water to wellsites. In 2012, we participated in the formation of Stingray Pressure Pumping LLC, or Stingray Pressure, Stingray Cementing LLC, or Stingray Cementing, and Stingray Logistics LLC, or Stingray Logistics, with an initial ownership interest in each entity of 50%. These entities provide well completion and other well services. In 2012, we also participated in the formation of Blackhawk Midstream LLC, or Blackhawk, and Timber Wolf Terminals LLC, or Timber Wolf, with an initial ownership interest of 50% in each entity. Blackhawk coordinates gathering, compression, processing and marketing activities in connection with the development of our Utica Shale acreage and Timber Wolf will operate a crude/condensate terminal and a sand transloading facility in Ohio. Also in 2012, we acquired a 22.5% equity interest in Windsor Midstream LLC, or Midstream, which owned a 28.4% equity interest in Coronado Midstream LLC, or Coronado, an entity that owns gas processing facilities in West Texas. Midstream sold its interest in Coronado in March 2015. In 2011 and 2012, we acquired an aggregate 40% equity interest in Bison Drilling and Field Services LLC, or Bison, which owns and operates drilling rigs and related equipment. Also in 2011, we acquired a 25% interest in Muskie Proppant LLC, or Muskie, which is engaged in the processing and sale of hydraulic fracturing grade sand. In 2014, we acquired a 25% equity interest in Sturgeon Acquisitions LLC, or Sturgeon. Sturgeon owns and operates sand mines that produce hydraulic fracturing grade sand. We are currently evaluating strategic alternatives with respect to some of these oil field service entities. In the fourth quarter of 2014, we contributed our investments in Stingray Pressure, Stingray Logistics, Bison and Muskie to Mammoth Energy Partners LP, or Mammoth, in exchange for a 30.5% limited partner interest in this newly formed limited partnership. Mammoth has filed a registration statement on Form S-1 with the SEC in connection with its proposed initial public offering. Mammoth originally intended to pursue the offering in 2015; however, Mammoth continues to evaluate market conditions and intends to launch the offering when commodity prices have recovered. See Note 3 to our consolidated financial statements included elsewhere in this report for additional information regarding these other investments.
Critical Accounting Policies and Estimates
Our disc ussion and analysis of our financial condition and results of operations are based upon consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We have identified certain of these policies as being of particular importance to the portrayal of our financial position and results of operations and which require the application of significant judgment by our management. We analyze our estimates including those related to oil and natural gas properties, revenue recognition, income taxes and commitments and contingencies, and base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these
39

Table of Contents
estimates under different assumptions or conditions. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements:
Oil and Natural Gas Properties. We use the full cost method of accounting for oil and natural gas operations. Accordingly, all costs, including non-productive costs and certain general and administrative costs directly associated with acquisition, exploration and development of oil and natural gas properties, are capitalized. Companies that use the full cost method of accounting for oil and gas properties are required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the oil and gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes or the cost center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted at 10% per annum, from proved reserves, based on the 12-month unweighted average of the first-day-of-the-month price for the prior twelve months, adjusted for any contract provisions or financial derivatives, if any, that hedge our oil and natural gas revenue, and excluding the estimated abandonment costs for properties with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if any, and (c) the lower of cost or market value of unproved properties included in the cost being amortized, including related deferred taxes for differences between the book and tax basis of the oil and natural gas properties. If the net book value, including related deferred taxes, exceeds the ceiling, an impairment or noncash writedown is required. Such capitalized costs, including the estimated future development costs and site remediation costs of proved undeveloped properties are depleted by an equivalent units-of-production method, converting gas to barrels at the ratio of six Mcf of gas to one barrel of oil. No gain or loss is recognized upon the disposal of oil and natural gas properties, unless such dispositions significantly alter the relationship between capitalized costs and proven oil and natural gas reserves. Oil and natural gas properties not subject to amortization consist of the cost of undeveloped leaseholds and totaled approximately $2.0 billion at September 30, 2015 and approximately $1.5 billion at December 31, 2014. These costs are reviewed quarterly by management for impairment, with the impairment provision included in the cost of oil and natural gas properties subject to amortization. Factors considered by management in its impairment assessment include our drilling results and those of other operators, the terms of oil and natural gas leases not held by production and available funds for exploration and development.
Ceiling Test. Companies that use the full cost method of accounting for oil and gas properties are required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the oil and gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes or the cost center ceiling (as defined in the preceding paragraph). If the net book value, including related deferred taxes, exceeds the ceiling, an impairment or noncash writedown is required. Ceiling test impairment can give us a significant loss for a particular period; however, future depletion expense would be reduced. A decline in oil and gas prices may result in an impairment of oil and gas properties. As a result of the decline in commodity prices, we recognized a ceiling test impairment of $594.8 million for the nine months ended September 30, 2015. If prices of oil, natural gas and natural gas liquids continue to decrease, we may be required to further write down the value of our oil and natural gas properties, which could negatively affect our results of operations.
Asset Retirement Obligations. We have obligations to remove equipment and restore land at the end of oil and gas production operations. Our removal and restoration obligations are primarily associated with plugging and abandoning wells and associated production facilities.
We account for abandonment and restoration liabilities under FASB ASC 410 which requires us to record a liability equal to the fair value of the estimated cost to retire an asset. The asset retirement liability is recorded in the period in which the obligation meets the definition of a liability, which is generally when the asset is placed into service. When the liability is initially recorded, we increase the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related long-lived asset. Upon settlement of the liability or the sale of the well, the liability is reversed. These liability amounts may change because of changes in asset lives, estimated costs of abandonment or legal or statutory remediation requirements.
The fair value of the liability associated with these retirement obligations is determined using significant assumptions, including current estimates of the plugging and abandonment or retirement, annual inflations of these costs, the productive life of the asset and our risk adjusted cost to settle such obligations discounted using our credit adjustment risk free interest rate. Changes in any of these assumptions can result in significant revisions to the estimated asset retirement obligation. Revisions to the asset retirement obligation are recorded with an offsetting change to the carrying amount of the related long-lived asset, resulting in prospective changes to depreciation, depletion and amortization expense and accretion of discount. Because of the subjectivity of assumptions and the relatively long life of most of our oil and natural gas assets, the costs to ultimately retire these assets may vary significantly from previous estimates.

Oil and Gas Reserve Quantities. Our estimate of proved reserves is based on the quantities of oil and natural gas that engineering and geological analysis demonstrate, with reasonable certainty, to be recoverable from established reservoirs in the future under current operating and economic parameters. Ryder Scott Company, L.P., Netherland, Sewell & Associates, Inc. and to a lesser extent our personnel have prepared reserve reports of our reserve estimates at December 31, 2014 on a well-by-well basis for our properties.
Reserves and their relation to estimated future net cash flows impact our depletion and impairment calculations. As a result, adjustments to depletion and impairment are made concurrently with changes to reserve estimates. Our reserve estimates and the projected cash flows derived from these reserve estimates have been prepared in accordance with the guidelines of the Securities and Exchange Commission, or SEC. The accuracy of our reserve estimates is a function of many factors including the following:

• | the quality and quantity of available data;

• | the interpretation of that data;

• | the accuracy of various mandated economic assumptions; and

• | the judgments of the individuals preparing the estimates.

Our proved reserve estimates are a function of many assumptions, all of which could deviate significantly from actual results. Therefore, reserve estimates may materially vary from the ultimate quantities of oil and natural gas eventually recovered.
Income Taxes. We use the asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities are recognized for the future tax consequences of (1) temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities and (2) operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future period when those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income during the period the rate change is enacted. Deferred tax assets are recognized in the year in which realization becomes determinable. Periodically, management performs a forecast of its taxable income to determine whether it is more likely than not that a valuation allowance is needed, looking at both positive and negative factors. A valuation allowance for our deferred tax assets is established, if in management's opinion, it is more likely than not that some portion will not be realized. At September 30, 2015, a valuation allowance of $5.0 million had been provided for state net operating loss and federal foreign tax credit deferred tax assets based on the uncertainty these assets may be realized.
Revenue Recognition. We derive almost all of our revenue from the sale of crude oil and natural gas produced from our oil and gas properties. Revenue is recorded in the month the product is delivered to the purchaser. We receive payment on substantially all of these sales from one to three months after delivery. At the end of each month, we estimate the amount of production delivered to purchasers that month and the price we will receive. Variances between our estimated revenue and actual payment received for all prior months are recorded at the end of the quarter after payment is received. Historically, our actual payments have not significantly deviated from our accruals.
Investments—Equity Method. Investments in entities greater than 20% and less than 50% and/or investments in which we have significant influence are accounted for under the equity method. Under the equity method, our share of investees’ earnings or loss is recognized in the statement of operations. In accordance with FASB ASC 825, "Financial Instruments," we had elected the fair value option of accounting for our equity method investment in Diamondback's stock. At the end of each reporting period, the quoted closing market price of Diamondback's stock is multiplied by the total shares owned by us and the resulting gain or loss is recognized in (loss) income from equity method investments in the consolidated statements of operations. As of September 30, 2015, the Company did not own any shares of Diamondback's common stock.
We review our investments to determine if a loss in value which is other than a temporary decline has occurred. If such loss has occurred, we recognize an impairment provision. For the period ended September 30, 2015, we recognized an impairment loss related to our investment in Grizzly of approximately $58.0 million. During the year ended December 31, 2014, we recognized an impairment of $12.1 million related to our investment in Tatex III.
Commitments and Contingencies. Liabilities for loss contingencies arising from claims, assessments, litigation or other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. We are involved in certain litigation for which the outcome is uncertain. Changes in the certainty and the ability to reasonably estimate a loss amount, if any, may result in the recognition and subsequent payment of legal liabilities.

Derivative Instruments and Hedging Activities. We seek to reduce our exposure to unfavorable changes in oil and natural gas prices by utilizing energy swaps, swaptions and fixed-price contracts. We follow the provisions of FASB ASC 815, “Derivatives and Hedging,” as amended. It requires that all derivative instruments be recognized as assets or liabilities in the balance sheet, measured at fair value. We estimate the fair value of all derivative instruments using established index prices and other sources. These values are based upon, among other things, futures prices, correlation between index prices and our realized prices, time to maturity and credit risk. The values reported in the financial statements change as these estimates are revised to reflect actual results, changes in market conditions or other factors.
The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. Designation is established at the inception of a derivative, but re-designation is permitted. For derivatives designated as cash flow hedges and meeting the effectiveness guidelines of FASB ASC 815, changes in fair value are recognized in accumulated other comprehensive income until the hedged item is recognized in earnings. Hedge effectiveness is measured at least quarterly based on the relative changes in fair value between the derivative contract and the hedged item over time. We recognize any change in fair value resulting from ineffectiveness immediately in earnings. There were no hedges designated as cash flow hedges during the nine months ended September 30, 2015.
RESULTS OF OPERATIONS
Comparison of the Three Months Ended September 30, 2015 and 2014
We reported a net loss of $388.2 million for the three months ended September 30, 2015 as compared to net income of $6.9 million for the three months ended September 30, 2014. This $395.1 million decrease in period-to-period net income was due primarily to an impairment charge of $594.8 million related to the decline in commodity prices, a 47% decrease in realized Mcfe prices to $3.87 from $7.29, a $5.7 million increase in lease operating expenses, an $8.4 million increase in interest expense and a $23.5 million increase in midstream gathering and processing expenses, partially offset by a 155% increase in net production to 59,530 MMcfe from 23,367 MMcfe and a $221.5 million decrease in income tax expense for the three months ended September 30, 2015 as compared to the three months ended September 30, 2014.
Oil and Gas Revenues. For the three months ended September 30, 2015, we reported oil and natural gas revenues of $230.4 million as compared to oil and natural gas revenues of $170.4 million during the same period in 2014. This $60.0 million, or 35%, increase in revenues was primarily attributable to a 155% increase in net production to 59,530 MMcfe from 23,367 MMcfe, partially offset by a 47% decrease in realized Mcfe prices to $3.87 from $7.29 due to a shift in our production mix toward natural gas and NGLs and the decline in commodity prices for the three months ended September 30, 2015 as compared to the three months ended September 30, 2014.
The following table summarizes our oil and natural gas production and related pricing for the three months ended September 30, 2015, as compared to such data for the three months ended September 30, 2014:

Gas equivalents (per Mcfe) | $ | 3.87 |  |  | $ | 7.29 |

Lease Operating Expenses. Lease operating expenses, or LOE, not including production taxes increased to $17.6 million for the three months ended September 30, 2015 from $11.9 million for the three months ended September 30, 2014. This increase was mainly the result of an increase in expenses related to contract labor, field supervision, ad valorem taxes, rentals, location and road repairs, water hauling and disposal, field telemetry and repairs and maintenance due to our increased production in the Utica Shale.
Production Taxes. Production taxes decreased $1.6 million to $3.6 million for the three months ended September 30, 2015 from $5.2 million for the three months ended September 30, 2014. This decrease was related to changes in our product mix and production location as well as a decrease in realized prices.
Midstream Gathering and Processing Expenses. Midstream gathering and processing expenses increased by $23.5 million to $42.2 million for the three months ended September 30, 2015 from $18.7 million for the same period in 2014. This increase was primarily attributable to midstream expenses related to our increased production volumes in the Utica Shale resulting from our 2015 and 2014 drilling activities.
Depreciation, Depletion and Amortization. Depreciation, depletion and amortization, or DD&A, expense increased to $90.3 million for the three months ended September 30, 2015, and consisted of $89.7 million in depletion of oil and natural gas properties and $0.6 million in depreciation of other property and equipment, as compared to total DD&A expense of $72.4 million for the three months ended September 30, 2014. This increase was due to an increase in our full cost pool as a result of our capital activities as well as an increase in our production, partially offset by an increase in our total proved reserves volume used to calculate our total DD&A expense.
General and Administrative Expenses. Net general and administrative expenses increased to $11.0 million for the three months ended September 30, 2015 from $8.9 million for the three months ended September 30, 2014. This $2.0 million increase was due to an increase in salaries, stock compensation expense and benefits resulting from an increased number of employees, increases in legal fees, travel expense, corporate fees and bank fees, partially offset by a decrease in franchise taxes and consulting expense and an increase in general and administrative costs related to exploration and development activity capitalized to the full cost pool.
Accretion Expense. Accretion expense remained relatively flat at $0.2 million for the three months ended September 30, 2015 and 2014.
Interest Expense. Interest expense increased to $14.1 million for the three months ended September 30, 2015 from $5.7 million for the three months ended September 30, 2014 due primarily to the issuance of $350.0 million of 6.625% Senior Notes due 2023 on April 21, 2015. We had no debt outstanding under our revolving credit facility for the three months ended September 30, 2015 as compared to $36.8 million weighted average debt outstanding under such facility for the same period in 2014. As of September 30, 2015 and 2014, no borrowings were outstanding under this credit facility. Additionally, we capitalized approximately $3.6 million and $3.4 million in interest expense to undeveloped oil and natural gas properties during the three months ended September 30, 2015 and September 30, 2014, respectively. This slight increase in capitalized interest in the 2015 period was the result of an increase in our undeveloped oil and natural gas properties.

Income Taxes. As of September 30, 2015, we had numerous temporary differences, which gave rise to a net deferred tax liability. Periodically, management performs a forecast of our taxable income to determine whether it is more likely than not that a valuation allowance is needed, looking at both positive and negative factors. A valuation allowance for our deferred tax assets is established if, in management's opinion, it is more likely than not that some portion will not be realized. At September 30, 2015, a valuation allowance of $5.0 million had been provided for certain state net operating losses and federal foreign tax credit deferred tax assets based on the uncertainty these assets may be realized. We recognized an income tax benefit of $216.6 million for the three months ended September 30, 2015.
Comparison of the Nine Months Ended September 30, 2015 and 2014
We reported a net loss of $394.0 million for the nine months ended September 30, 2015 as compared to net income of $137.3 million for the nine months ended September 30, 2014. This 387% decrease in period-to-period net income was due primarily to an impairment charge of $594.8 million related to the decline in commodity prices, a 52% decrease in realized Mcfe prices to $3.68 from $7.66, a $15.2 million increase in lease operating expenses, a $63.2 million increase in midstream gathering and processing expenses and a $22.9 million increase in interest expense, partially offset by a 168% increase in net production to 140,856 MMcfe from 52,586 MMcfe for the nine months ended September 30, 2015 as compared to the nine months ended September 30, 2014. The nine months ended September 30, 2014 also included $84.8 million of income recognized from our equity method investment in Blackhawk and $89.3 million of income recognized from our former equity method investment in Diamondback.
Oil and Gas Revenues. For the nine months ended September 30, 2015, we reported oil and natural gas revenues of $518.8 million as compared to oil and natural gas revenues of $402.7 million during the same period in 2014. This $116.0 million, or 29%, increase in revenues was primarily attributable to a 168% increase in net production to 140,856 MMcfe from 52,586 MMcfe, partially offset by a 52% decrease in realized Mcfe prices to $3.68 from $7.66 due to a shift in our production mix toward natural gas and NGLs and the decline in commodity prices.
The following table summarizes our oil and natural gas production and related pricing for the nine months ended September 30, 2015, as compared to such data for the nine months ended September 30, 2014:

| Nine months ended September 30,

Lease Operating Expenses. Lease operating expenses, or LOE, not including production taxes increase d to $51.4 million for the nine months ended September 30, 2015 from $36.2 million for the nine months ended September 30, 2014. This increase was mainly the result of an increase in expenses related to contract labor and field supervision, environmental services, location repairs, rentals, repair and maintenance, ad valorem taxes and water hauling and disposal due to our increased production in the Utica Shale.
Production Taxes. Production taxes decrease d $7.6 million to $11.2 million for the nine months ended September 30, 2015 from $18.8 million for the same period in 2014. This decrease was primarily related to changes in our product mix and production location as well as a decrease in realized prices.
Midstream Gathering and Processing Expenses. Midstream gathering and processing expenses increase d by $63.2 million to $100.5 million for the nine months ended September 30, 2015 from $37.3 million for the same period in 2014. This increase

was primarily attributable to midstream expenses related to our increased production volumes in the Utica Shale resulting from our 2015 and 2014 drilling activities.
Depreciation, Depletion and Amortization. Depreciation, depletion and amortization, or DD&A, expense increase d to $251.4 million for the nine months ended September 30, 2015, and consisted of $249.6 million in depletion of oil and natural gas properties and $1.8 million in depreciation of other property and equipment, as compared to total DD&A expense of $185.3 million for the nine months ended September 30, 2014. This increase was due to an increase in our full cost pool as a result of our capital activities as well as an increase in our production, partially offset by an increase in our total proved reserves volume used to calculate our total DD&A expense.
General and Administrative Expenses. Net general and administrative expenses increase d to $31.3 million for the nine months ended September 30, 2015 from $28.8 million for the nine months ended September 30, 2014. This $2.5 million increase was due to an increase in salaries and benefits resulting from an increased number of employees, increases in legal expense, travel expense and bank fees, partially offset by a decrease in stock compensation expense, corporate fees, consulting expense and franchise taxes and an increase in general and administrative costs related to exploration and development activity capitalized to the full cost pool.
Accretion Expense. Accretion expense remained relatively flat at $0.6 million for the nine months ended September 30, 2015 and 2014.
Interest Expense. Interest expense increase d to $34.9 million for the nine months ended September 30, 2015 from $12.0 million for the nine months ended September 30, 2014 due primarily to the issuance of $300.0 million in additional 7.75% Senior Notes due 2020 on August 18, 2014, the issuance of $350.0 million of 6.625% Senior Notes due 2023 on April 21, 2015 and increased borrowings under our revolving credit facility. Total weighted debt outstanding under our revolving credit facility was $62.3 million for the nine months ended September 30, 2015 as compared to $17.2 million for the same period in 2014. As of September 30, 2015 and 2014, we had no debt outstanding under our revolving credit facility. Additionally, we capitalized approximately $12.0 million and $9.6 million in interest expense to undeveloped oil and natural gas properties during the nine months ended September 30, 2015 and September 30, 2014, respectively. This increase in capitalized interest during the 2015 period was the result of an increase in our undeveloped oil and natural gas properties.
Income Taxes. As of September 30, 2015, we had numerous temporary differences, which gave rise to a net deferred tax liability. Periodically, management performs a forecast of our taxable income to determine whether it is more likely than not that a valuation allowance is needed, looking at both positive and negative factors. A valuation allowance for our deferred tax assets is established if, in management's opinion, it is more likely than not that some portion will not be realized. At September 30, 2015, a valuation allowance of $5.0 million had been provided for state net operating loss and federal tax credit deferred tax assets based on the uncertainty these assets may be realized. We recognized an income tax benefit of $219.3 million for the nine months ended September 30, 2015.
Liquidity and Capital Resources
Overview. Historically, our primary sources of funds have been cash flow from our producing oil and natural gas properties, borrowings under our credit facility and the issuances of equity and debt securities. Our ability to access any of these sources of funds can be significantly impacted by decreases in oil and natural gas prices or oil and natural gas production. During 2014, we received net proceeds of $312.0 million from the sale of our 7.75% Senior Notes due 2020, aggregate net proceeds of $258.4 million from the sale of shares of our Diamondback common stock in 2014 and also received net proceeds of $84.8 million from the sale of Blackhawk's equity interest in Ohio Gathering Company, LLC and Ohio Condensate Company, LLC.
On April 21, 2015, we issued 10,925,000 shares of our common stock in an underwritten public offering (which included the 1,425,000 shares of our common stock sold pursuant to the option to purchase additional shares of our common stock granted by us to, and exercised in full by, the underwriters). The aggregate net proceeds from this equity offering were approximately $501.9 million (after deducting underwriting discounts and commissions and estimated offering expenses). We used a portion of the net proceeds from this equity offering to fund our acquisition of Paloma, with the remaining net proceeds to be used for general corporate purposes, including the funding of a portion of our 2015 capital development plans.
On April 21, 2015, we also completed an offering of $350.0 million in aggregate principal amount of our new 6.625% senior notes due 2023 to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to certain non-U.S. persons in accordance with Regulation S under the Securities Act. This offering is discussed in more detail below.

On June 12, 2015, we issued 11,500,000 shares of our common stock in an underwritten public offering (which included 1,500,000 shares sold pursuant to an option to purchase additional shares of our common stock granted to and exercised by the underwriters in full). The net proceeds from the equity offering (including the net proceeds from the sale of the shares of common stock to the underwriters under their option to purchase additional shares) were approximately $479.8 million. We used a portion of these net proceeds to fund the acquisition of certain acreage and other assets in the Utica Shale in Ohio from AEU and intend to use the remaining funds for general corporate purposes, including the funding of a portion of our 2015 capital development plans.
Net cash flow provided by operating activities was $235.1 million for the nine months ended September 30, 2015 as compared to net cash flow provided by operating activities of $285.9 million for the same period in 2014. This decrease was primarily the result of an increase in cash receipts from our oil and natural gas purchasers due to a 168% increase in our net Mcfe production partially offset by a 52% decrease in net realized Mcfe prices, partially offset by an increase in our operating expenses. In addition, in January 2014, we recognized proceeds of $84.8 million from the sale of Blackhawk's equity interest in Ohio Gathering Company, LLC and Ohio Condensate Company, LLC and, in the first quarter of 2015, we received net proceeds of $7.2 million from the release of escrow from the Blackhawk sale.
Net cash used in investing activities for the nine months ended September 30, 2015 was $1.4 billion as compared to $904.0 million for the same period in 2014. During the nine months ended September 30, 2015, we spent $1.4 billion in additions to oil and natural gas properties, of which $146.6 million was spent on our 2015 drilling and recompletion programs, $425.6 million was spent on expenses attributable to the wells spud and recompleted during 2014, $707.4 million was spent on the AEU and Paloma acquisitions, $9.4 million was spent on facility enhancements, $3.1 million was spent on plugging costs and $47.5 million was spent on lease related costs, primarily the acquisition of leases in the Utica Shale, with the remainder attributable mainly to capitalized general and administrative expenses. In addition, $13.8 million was invested in Grizzly during the nine months ended September 30, 2015. We did not make any investments in our other equity investments during the nine months ended September 30, 2015.
Net cash provided by financing activities for the nine months ended September 30, 2015 was $1.2 billion as compared to net cash provided by financing activities of $312.1 million for the same period in 2014. The 2015 amount provided by financing activities is primarily attributable to the net proceeds of $343.6 million from the issuance of our 6.625% senior notes due 2023 and net proceeds of $981.6 million from our 2015 equity offerings and exercise of stock options, partially offset by net payments under our revolving credit facility.
Credit Facility. On December 27, 2013, we entered into an amended and restated credit agreement with The Bank of Nova Scotia, as administrative agent, sole lead arranger and sole bookrunner, Amegy Bank National Association, as syndication agent, KeyBank National Association, as documentation agent, and the other lenders, which we refer to as the amended and restated credit agreement. The amended and restated credit agreement provides for a maximum facility amount of $1.5 billion and matures on June 6, 2018.
On April 23, 2014, we entered into a first amendment to the amended and restated credit agreement. The first amendment increased the letter of credit sublimit from $20.0 million to $70.0 million and provided for an increase in the borrowing base availability from $150.0 million to $275.0 million. The first amendment also made certain changes to the lenders and their respective lending commitments thereunder.
On November 26, 2014, we entered into a second amendment to the amended and restated credit agreement. The second amendment changed the definition of EBITDAX to exclude proceeds from the disposition of equity method investments and changed the ratio of funded debt to EBITDAX to be the ratio of net funded debt to EBITDAX. Net funded debt is funded debt less the amount of cash and short-term investments at the end of the relevant fiscal quarter. The second amendment requires the ratio of net funded debt to EBITDAX to be less than 3.50 to 1.00 for the period December 31, 2014 through June 30, 2015 and then less than 3.25 to 1.00 for the periods thereafter. Further, the second amendment increased the letter of credit sublimit from $70.0 million to $125.0 million and provided for an increase in the borrowing base availability from $275.0 million to $450.0 million.
As of April 10, 2015, we entered into a third amendment to the amended and restated credit agreement. The third amendment increased the borrowing base from $450.0 million to $575.0 million and increased our basket for unsecured debt issuances to $1.2 billion. The third amendment also made certain changes to the lenders and their respective lending commitments thereunder.

On May 29, 2015, we entered into a fourth amendment to the amended and restated credit agreement. The fourth amendment increased the letter of credit sublimit from $125.0 million to $150.0 million. Additionally, we received consent from our lenders to incur certain new secured indebtedness, limited to $30.0 million, to finance the construction of our new Oklahoma City headquarters. The lenders also agreed to waive certain provisions of the amended and restated credit agreement that may prohibit the construction loan.
On September 18, 2015, we entered into a fifth amendment to the amended and restated credit agreement. The fifth amendment among other things, (a) increased our borrowing base from $575.0 million to $700.0 million, (b) increased the maximum permitted ratio of net funded debt to EBITDAX from a level of 3.25 to 1.00 to 4.00 to 1.00, (c) revised our letter of credit sublimit from $150.0 million to the greater of (i) $150.0 million and (ii) 40% of the borrowing base existing at such time, (d) added an investments basket with a $100.0 million limitation for investments in joint ventures formed to own and operate midstream assets, (e) revised the limit of the general indebtedness basket from a current limit of $10.0 million in the aggregate at any time outstanding to a limit equal to the greater of (i) $10.0 million in the aggregate at any time outstanding and (ii) two percent (2%) of the borrowing base at the time such indebtedness is incurred, (f) added a dispositions basket covering dispositions of contracts (and rights or interests therein or thereunder) or other arrangements constituting a release of natural gas interstate transportation capacity, which dispositions do not (when considered cumulatively, and taken together with other related transactions and contractual arrangements) deprive us of the benefit of any material portion of our mineral interests, and (g) revised the provisions that limit our ability to enter into swap contracts.
As of September 30, 2015, we had no balance outstanding under our revolving credit facility and total funds available for borrowing, after giving effect to an aggregate of $177.1 million of letters of credit, was $522.9 million. This facility is secured by substantially all of our assets. Our wholly-owned subsidiaries guarantee our obligations under our revolving credit facility.
Advances under our revolving credit agreement may be in the form of either base rate loans or eurodollar loans. The interest rate for base rate loans is equal to (1) the applicable rate, which ranges from 0.50% to 1.50%, plus (2) the highest of: (a) the federal funds rate plus 0.50%, (b) the rate of interest in effect for such day as publicly announced from time to time by agent as its “prime rate,” and (c) the eurodollar rate for an interest period of one month plus 1.00%. The interest rate for eurodollar loans is equal to (1) the applicable rate, which ranges from 1.50% to 2.50%, plus (2) the London interbank offered rate that appears on pages LIBOR01 or LIBOR02 of the Reuters screen that displays such rate for deposits in U.S. dollars, or, if such rate is not available, the rate as administered by ICE Benchmark Administration (or any other person that takes over administration of such rate) per annum equal to the offered rate on such other page or other service that displays an average London interbank offered rate as administered by ICE Benchmark Administration (or any other person that takes over the administration of such rate) for deposits in U.S. dollars, or, if such rate is not available, the average quotations for three major New York money center banks of whom the agent shall inquire as the “London Interbank Offered Rate” for deposits in U.S. dollars.
Our revolving credit facility contains customary negative covenants including, but not limited to, restrictions on our and our subsidiaries' ability to: incur indebtedness; grant liens; pay dividends and make other restricted payments; make investments; make fundamental changes; enter into swap contracts and forward sales contracts; dispose of assets; change the nature of their business; and enter into transactions with their affiliates. The negative covenants are subject to certain exceptions as specified in our revolving credit facility. Our revolving credit facility also contains certain affirmative covenants, including, but not limited to the following financial covenants: (1) the ratio of net funded debt to EBITDAX (net income, excluding (i) any non-cash revenue or expense associated with swap contracts resulting from ASC 815 and (ii) any cash or non-cash revenue or expense attributable to minority investment plus without duplication and, in the case of expenses, to the extent deducted from revenues in determining net income, the sum of (a) the aggregate amount of consolidated interest expense for such period, (b) the aggregate amount of income, franchise, capital or similar tax expense (other than ad valorem taxes) for such period, (c) all amounts attributable to depletion, depreciation, amortization and asset or goodwill impairment or writedown for such period, (d) all other non-cash charges, (e) exploration costs deducted in determining net income under successful efforts accounting, (f) actual cash distributions received from minority investments, (g) to the extent actually reimbursed by insurance, expenses with respect to liability on casualty events or business interruption, and (h) all reasonable transaction expenses related to dispositions and acquisitions of assets, investments and debt and equity offerings (provided that expenses related to any unsuccessful dispositions will be limited to $3.0 million in the aggregate) for a twelve-month period may not be greater than 4.00 to 1.00; and (2) the ratio of EBITDAX to interest expense for a twelve-month period may not be less than 3.00 to 1.00. We were in compliance with these financial covenants at September 30, 2015.
Senior Notes. In October 2012, December 2012 and August 2014, we issued an aggregate of $600.0 million in principal amount of our 7.75% senior notes due 2020 under an indenture among us, our subsidiary guarantors and Wells Fargo Bank, National Association, as the trustee. These senior notes are treated as a single class of debt securities under the senior note
47

Table of Contents
indenture and are referred to collectively as the Old Notes. Interest on the Old Notes accrues at a rate of 7.75% per annum on the outstanding principal amount from October 17, 2012, payable semi-annually on May 1 and November 1 of each year, commencing on May 1, 2013. The Old Notes are senior unsecured obligations and rank equally in the right of payment with all of our other senior indebtedness and senior in right of payment to any of our future subordinated indebtedness. We may redeem some or all of the Old Notes at any time on or after November 1, 2016, at the redemption prices listed in the senior note indenture. Prior to November 1, 2016, we may redeem the Old Notes at a price equal to 100% of the principal amount plus a “make-whole” premium. In addition, prior to November 1, 2015, we may redeem up to 35% of the aggregate principal amount of the Notes with the net proceeds of certain equity offerings, provided that at least 65% of the aggregate principal amount of the Notes initially issued remains outstanding immediately after such redemption.
In April 2015, we issued $350.0 million in aggregate principal amount of our 6.625% senior unsecured notes due 2023, which we refer to as the April Notes and, together with the Old Notes, the Notes, to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to certain non-U.S. persons in accordance with Regulation S under the Securities Act, or the April Notes Offering. We used a portion of the net proceeds from the April Notes Offering, together with the net proceeds from our concurrent equity offering, to repay all amounts outstanding at such time under our revolving credit facility and to fund our acquisition of Paloma and intend to use the remaining net proceeds from these offerings for general corporate purposes, including the funding of a portion of our 2015 capital development plans.
The April Notes were issued under a new indenture, dated as of April 21, 2015, among us, our subsidiary guarantors and Wells Fargo Bank, N.A., as trustee. Interest on the April Notes accrues at a rate of 6.625% per annum on the outstanding principal amount thereof from April 21, 2015, payable semi-annually on May 1 and November 1 of each year, commencing on November 1, 2015. The April Notes will mature on May 1, 2023. The April Notes are our senior unsecured obligations and rank equally in right of payment with all of our other senior indebtedness, including the Old Notes, and senior in right of payment to any of our future subordinated indebtedness. We may redeem some or all of the April Notes at any time on or after May 1, 2018, at the redemption prices listed in the indenture relating to the April Notes. Prior to May 1, 2018, we may redeem all or a portion of the April Notes at a price equal to 100% of the principal amount of the April Notes plus a “make-whole” premium and accrued and unpaid interest to the redemption date. In addition, any time prior to May 1, 2018, we may redeem the April Notes in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the April Notes issued prior to such date at a redemption price of 106.625%, plus accrued and unpaid interest to the redemption date, with an amount equal to the net cash proceeds from certain equity offerings.
All of our existing and future restricted subsidiaries that guarantee our secured revolving credit facility or certain other debt guarantee the Notes, provided, however, that the Notes are not guaranteed by Grizzly Holdings, Inc. and will not be guaranteed by any of our future unrestricted subsidiaries. The guarantees rank equally in the right of payment with all of the senior indebtedness of the subsidiary guarantors and senior in the right of payment to any future subordinated indebtedness of the subsidiary guarantors. The Notes and the guarantees are effectively subordinated to all of our and the subsidiary guarantors' secured indebtedness (including all borrowings and other obligations under our amended and restated credit agreement) to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to all indebtedness and other liabilities of any of our subsidiaries that do not guarantee the Notes.
If we experience a change of control (as defined in the senior note indentures relating to the Old Notes and the April Notes), we will be required to make an offer to repurchase the Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase. If we sell certain assets and fail to use the proceeds in a manner specified in our senior note indentures, we will be required to use the remaining proceeds to make an offer to repurchase the Notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase. The senior note indentures relating to the Old Notes and the April Notes contain certain covenants that, subject to certain exceptions and qualifications, among other things, limit our ability and the ability of our restricted subsidiaries to incur or guarantee additional indebtedness, make certain investments, declare or pay dividends or make distributions on capital stock, prepay subordinated indebtedness, sell assets including capital stock of restricted subsidiaries, agree to payment restrictions affecting our restricted subsidiaries, consolidate, merge, sell or otherwise dispose of all or substantially all of our assets, enter into transactions with affiliates, incur liens, engage in business other than the oil and gas business and designate certain of our subsidiaries as unrestricted subsidiaries. Under the indenture relating to the April Notes, certain of these covenants are subject to termination upon the occurrence of certain events, including in the event the April Notes are ranked as "investment grade".
In connection with the April Notes Offering, we and our subsidiary guarantors entered into a registration rights agreement with the representatives of the initial purchasers, dated as of April 21, 2015, pursuant to which we agreed to file a registration statement with respect to an offer to exchange the April Notes for a new issue of substantially identical debt securities registered
48

Table of Contents
under the Securities Act. The registration statement relating to the exchange offer for the April Notes was filed on August 24, 2015 and declared effective by the SEC on September 4, 2015. The exchange offer for the April Notes was completed on October 13, 2015.
Capital Expenditures. Our recent capital commitments have been primarily for the execution of our drilling programs, for acquisitions (primarily in the Utica Shale), to fund Grizzly's delineation drilling program and preparation of the Algar Lake facility and for investments in entities that may provide services to facilitate the development of our acreage. Our strategy is to continue to (1) increase cash flow generated from our operations by undertaking new drilling, workover, sidetrack and recompletion projects to exploit our existing properties, subject to economic and industry conditions, (2) pursue acquisition and disposition opportunities and (3) pursue business integration opportunities.
Of our net reserves at December 31, 2014, 51.4% were categorized as proved undeveloped. Our proved reserves will generally decline as reserves are depleted, except to the extent that we conduct successful exploration or development activities or acquire properties containing proved developed reserves, or both. To realize reserves and increase production, we must continue our exploratory drilling, undertake other replacement activities or use third parties to accomplish those activities.
From January 1, 2015 through November 1, 2015, we spud 41 gross (33.6 net) wells in the Utica Shale. We currently expect our 2015 capital expenditures to be $649.0 million to $657.0 million to spud 49 to 53 gross (39 to 41 net) wells on our Utica Shale acreage. In addition, we currently expect to spend $85.0 million to $95.0 million in 2015 to acquire additional acreage in the Utica Shale.
From January 1, 2015 through November 1, 2015, we recompleted 35 existing wells and spud no new wells at our WCBB field. In our Hackberry fields, from January 1, 2015 through November 1, 2015, we recompleted 33 existing wells and spud no new wells. We currently expect our 2015 capital expenditures to be $18.0 million to $20.0 million for maintenance capital expenditures and recompletions in Southern Louisiana.
From January 1, 2015 through November 1, 2015, no new wells were spud on our Niobrara Formation acreage. We do not currently anticipate any capital expenditures in the Niobrara Formation in 2015.
As of September 30, 2015, our net investment in Grizzly was approximately $99.5 million. As of September 30, 2105, we have invested $13.8 million in Grizzly. We do not currently anticipate any additional material capital expenditures in 2015 related to Grizzly's activities.
We had no material capital expenditures during the nine months ended September 30, 2015 related to our interests in Thailand. We do not currently anticipate any additional capital expenditures in Thailand in 2015.
In an effort to facilitate the development of our Utica Shale and other domestic acreage, we have invested in entities that can provide services that are required to support our operations. See "-2015 Updates Regarding Our Equity Investments-Other Investments" and Note 3 to our consolidated financial statements included elsewhere in this report for additional information regarding these other investments. In the year ended December 31, 2014, we invested approximately $43.6 million in these entities. In the nine months ended September 30, 2015, we did not make any additional investments in these entities, and we do not currently anticipate any capital expenditures related to these entities in 2015.
During 2015, we have continued to focus on operational efficiencies in an effort to reduce our overall well costs and deliver better results in a more economical manner. To do so, we have leveraged the lower commodity price environment to gain access to higher-quality equipment and superior services for reduced costs, which has led to increased productivity. To further benefit from these efficiencies and cost savings, we elected to accelerate our completion activities in advance of the winter months when operations are less efficient and more costly due to the cold weather. We now anticipate that we will complete approximately ten additional net Utica wells this year. We estimate these activities will increase our anticipated expenditures in 2015 by approximately $60.0 million. As a result, our total capital expenditures for 2015 are currently estimated to be in the range of $667.0 million to $677.0 million. In addition, we currently expect to spend $85.0 million to $95.0 million in 2015 to acquire additional Utica Shale acreage. Our total capital expenditures spent during the nine months ended September 30, 2015 were approximately $649.3 million, including leasehold acquisitions but excluding our AEU and Paloma acquisitions. Approximately 97% of our 2015 estimated capital expenditures are currently expected to be spent in the Utica Shale. This range is down from the $872.9 million spent in 2014, excluding Utica leasehold acquisitions and the Rhino acquisition, primarily due to current commodity prices and a desire to maintain a strong liquidity position.

Table of Contents
We intend to continue to monitor pricing and cost developments and make adjustments to our future capital expenditure programs as warranted. Strong results from our existing production base and efficiencies realized in our completion activities have resulted in our 2015 production trending ahead of expectations. As a result, and combined with the weakness in natural gas commodity pricing, we have made the decision to temporarily voluntarily curtail approximately 100 MMcfe per day of production beginning November 1, 2015 through early 2016 and idle completion crews and suspend our hydraulic fracturing activities during the first quarter of 2016.
We believe that our cash flow from operations, cash on hand (including proceeds from our recent debt and equity offerings) and borrowings under our loan facilities will be sufficient to meet our normal recurring operating needs and capital requirements for the next twelve months. In the event we elect to further expand or accelerate our drilling program or pursue additional acquisitions, or Grizzly's oil sands projects require additional investments, we may be required to obtain additional funds which we would seek to do through traditional borrowings, offerings of debt or equity securities or other means, including the sale of assets. We regularly evaluate new acquisition opportunities. Needed capital may not be available to us on acceptable terms or at all. If we are unable to obtain funds when needed or on acceptable terms, we may be required to delay or curtail implementation of our business plan or not be able to complete acquisitions that may be favorable to us.
Commodity Price Risk
The volatility of the energy markets makes it extremely difficult to predict future oil and natural gas price movements with any certainty. For example, during the past six years, the West Texas Intermediate posted price for crude oil has ranged from a low of $34.03 per barrel in February 2009 to a high of $113.39 per barrel in April 2011. The Henry Hub spot market price of natural gas has ranged from a low of $1.82 per million British thermal units, or MMBtu, in April 2012 to a high of $7.51 per MMBtu in January 2010. On October 30, 2015, the West Texas Intermediate posted price for crude oil was $46.10 per barrel and the Henry Hub spot market price of natural gas was $2.29 per MMBtu. Any substantial decline in the price of oil and natural gas will likely have a material adverse effect on our operations, financial condition and level of expenditures for the development of our oil and natural gas reserves, and may result in write downs of oil and natural gas properties due to ceiling test limitations. To mitigate the effects of commodity price fluctuations on our oil and natural gas production, we have entered into certain fixed price swaps, swaptions and basis swaps. See Item 3. Quantitative and Qualitative Disclosures about Market Risk for information regarding our open fixed price swaps, swaptions and basis swaps at September 30, 2015.
Commitments
In connection with our acquisition in 1997 of the remaining 50% interest in the WCBB properties, we assumed the seller's (Chevron) obligation to contribute approximately $18,000 per month through March 2004, to a plugging and abandonment trust and the obligation to plug a minimum of 20 wells per year for 20 years commencing March 11, 1997. Chevron retained a security interest in production from these properties until our abandonment obligations to Chevron have been fulfilled. Beginning in 2009, we could access the trust for use in plugging and abandonment charges associated with the property, but have not yet done so. As of September 30, 2015, the plugging and abandonment trust totaled approximately $3.1 million. At September 30, 2015, we have plugged 463 wells at WCBB since we began our plugging program in 1997, which management believes fulfills our current minimum plugging obligation.
Contractual and Commercial Obligations
We have various contractual obligations in the normal course of our operations and financing activities. There have been no material changes to our contractual obligations from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2014.
Off-balance Sheet Arrangements
We had no off-balance sheet arrangements as of September 30, 2015.
New Accounting Pronouncements
In April 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2014-08: Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 changes the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other material disposal transactions that do not meet the revised definition of a discontinued operation. Under the updated standard, a

disposal of a component or group of components of an entity is required to be reported as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the component or group of components of the entity (1) has been disposed of by a sale, (2) has been disposed of other than by sale or (3) is classified as held for sale. The ASU is effective for annual and interim periods beginning after December 15, 2014, however, early adoption is permitted. We early adopted this ASU on a prospective basis beginning with the second quarter of 2014. The adoption did not have a material impact on our consolidated financial statements.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the new standard is for the recognition of revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which the company expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced revenue disclosures, provide guidance for transactions that were not previously addressed comprehensively and improve guidance for multiple-element arrangements. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those years, using either a full or a modified retrospective application approach. In July 2015, the FASB decided to defer the effective date by one year (until 2018). We are in the process of evaluating the impact on our consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements - Going Concern (Subtopic 205-40)." The new guidance addresses management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and in certain circumstances to provide related footnote disclosures. The standard is effective for the annual period ending after December 15, 2016 and for annual and interim periods thereafter. Early adoption is permitted. We do not believe that the adoption of this guidance will have a material impact on our consolidated financial statements.
In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03)." To simplify presentation of debt issuance costs, ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. ASU 2015-03 is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. We are in the process of assessing the effects of adoption of this new guidance.
In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments." The guidance eliminates the requirement to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. Measurement period adjustments are calculated as if they were known at the acquisition date, but are recognized in the reporting period in which they are determined. Additional disclosures are required about the impact on current-period income statement line items of adjustments that would have been recognized in prior periods if prior-period information had been revised. The guidance is effective for annual periods beginning after December 15, 2015 and is to be applied prospectively to adjustments of provisional amounts that occur after the effective date. Early application is permitted. We are in the process of evaluating the impact on our consolidated financial statements.

ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our revenues, operating results, profitability, future rate of growth and the carrying value of our oil and natural gas properties depend primarily upon the prevailing prices for oil and natural gas. Historically, oil and natural gas prices have been volatile and are subject to fluctuations in response to changes in supply and demand, market uncertainty and a variety of additional factors, including: worldwide and domestic supplies of oil and natural gas; the level of prices, and expectations about future prices, of oil and natural gas; the cost of exploring for, developing, producing and delivering oil and natural gas; the expected rates of declining current production; weather conditions, including hurricanes, that can affect oil and natural gas operations over a wide area; the level of consumer demand; the price and availability of alternative fuels; technical advances affecting energy consumption; risks associated with operating drilling rigs; the availability of pipeline capacity; the price and level of foreign imports; domestic and foreign governmental regulations and taxes; the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls; political instability or armed conflict in oil and natural gas producing regions; and the overall economic environment.
These factors and the volatility of the energy markets make it extremely difficult to predict future oil and natural gas price movements with any certainty. For example, during the past six years, the West Texas Intermediate posted price for crude oil has ranged from a low of $34.03 per barrel, or Bbl, in February 2009 to a high of $113.39 per Bbl in April 2011. The Henry

Table of Contents
Hub spot market price of natural gas has ranged from a low of $1.82 per MMBtu in April 2012 to a high of $7.51 per MMBtu in January 2010. On October 30, 2015, the West Texas Intermediate posted price for crude oil was $46.10 per barrel and the Henry Hub spot market price of natural gas was $2.29 per MMBtu. Any substantial decline in the price of oil and natural gas will likely have a material adverse effect on our operations, financial condition and level of expenditures for the development of our oil and natural gas reserves, and may result in write downs of oil and natural gas properties due to ceiling test limitations.
To mitigate the effects of commodity price fluctuations on our oil and natural gas production, we had the following open fixed price swaps, swaptions and basis swaps at September 30, 2015:

| Daily Volume (Bbls/day) |  | Weighted Average Price
Fixed Price Swaps: |  |  |
October 2015 - June 2016 | 2,500 |  |  | $ | 62.38 |

| Daily Volume (MMBtu/day) |  | Weighted Average Price
Fixed Price Swaps and Swaptions: |  |  |
October 2015 | 322,500 |  |  | $ | 3.79 |
November 2015 - December 2015 | 282,500 |  |  | $ | 3.91 |
January 2016 - March 2016 | 377,500 |  |  | $ | 3.63 |
April 2016 | 367,500 |  |  | $ | 3.62 |
May 2016 - December 2016 | 297,500 |  |  | $ | 3.52 |
January 2017 - June 2017 | 182,500 |  |  | $ | 3.59 |
July 2017 - December 2017 | 120,000 |  |  | $ | 3.40 |
January 2018 - December 2018 | 70,000 |  |  | $ | 3.35 |
January 2019 - March 2019 | 20,000 |  |  | $ | 3.37 |

| Daily Volume (Gal/day) |  | Weighted Average Price
Fixed Price Swaps: |  |  |
October 2015 - December 2016 | 42,000 |  |  | $ | 0.48 |

| Daily Volume (MMBtu/day) |  | Hedged Differential
Basis Swaps: |  |  |
October 2015 | 40,000 |  |  | $ | 0.02 |
November 2015 - March 2016 | 70,000 |  |  | $ | 0.11 |
April 2016 - December 2016 | 40,000 |  |  | $ | 0.02 |

Under our 2015 contracts, we have hedged approximately 47% to 49% of our estimated 2015 production. Such arrangements may expose us to risk of financial loss in certain circumstances, including instances where production is less than expected or oil prices increase. These fixed price swaps are recorded at fair value pursuant to FASB ASC 815 and related pronouncements. At September 30, 2015, we had a net asset derivative position of $161.7 million as compared to a net asset derivative position of $0.2 million as of September 30, 2014, related to our fixed price swaps. Utilizing actual derivative contractual volumes, a 10% increase in underlying commodity prices would have reduced the fair value of these instruments by approximately $69.0 million, while a 10% decrease in underlying commodity prices would have increased the fair value of these instruments by approximately $69.0 million. However, any realized derivative gain or loss would be substantially offset by a decrease or increase, respectively, in the actual sales value of production covered by the derivative instrument.
Our revolving amended and restated credit agreement is structured under floating rate terms, as advances under this facility may be in the form of either base rate loans or eurodollar loans. As such, our interest expense is sensitive to fluctuations in the

prime rates in the U.S. or, if the eurodollar rates are elected, the eurodollar rates. As of September 30, 2015, we had no variable interest rate borrowings outstanding; therefore, an increase in interest rates would not have impacted our interest expense. As of September 30, 2015, we did not have any interest rate swaps to hedge our interest risks.

ITEM 4. | CONTROLS AND PROCEDURES

Evaluation of Disclosure Control and Procedures. Under the direction of our Chief Executive Officer and President and our Chief Financial Officer, we have established disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. The disclosure controls and procedures are also intended to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer and President and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.
As of September 30, 2015, an evaluation was performed under the supervision and with the participation of management, including our Chief Executive Officer and President and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act. Based upon our evaluation, our Chief Executive Officer and President and our Chief Financial Officer have concluded that, as of September 30, 2015, our disclosure controls and procedures are effective.
Changes in Internal Control over Financial Reporting. There have not been any changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.
