GASTAR EXPLORATION INC. AND SUBSIDIARIES

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Description of Business

Gastar Exploration Inc. (the “Company” or “Gastar”) is a pure play Mid-Continent independent energy company engaged in the exploration, development and production of oil, condensate, natural gas and NGLs in the United States.  Gastar’s principal business activities include the identification, acquisition, and subsequent exploration and development of oil and natural gas properties with an emphasis on unconventional reserves, such as shale resource plays.  Gastar holds a concentrated acreage position in the normally pressured oil window of the STACK Play, an area of central Oklahoma which is home to multiple oil and natural gas-rich reservoirs including the Oswego limestone, Meramec and Osage bench formations within the Mississippi Lime, the Woodford shale and Hunton limestone formations.    

2. Going Concern

These unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2018 have been prepared assuming the Company will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of issuance of these condensed consolidated financial statements.    

As previously reported, the Company’s ability to raise additional capital to pursue corporate objectives such as a drilling and development program at a cost of capital that enables the Company to achieve a profit has been significantly adversely affected by its current capital structure. While, historically, the Company has been able to reduce capital expenditures to better match available capital resources, for the reasons described below, the Company has reduced capital expenditures by suspending its operated drilling program.  A sustained suspension of the operated drilling program could create the potential for deterioration of its core business.  In addition, as a result of the recent further significant deterioration of the Company’s equity trading values, the Company’s common and preferred stock were delisted from the NYSE American LLC stock exchange (the “NYSE American”) and began trading on the OTCQB Venture Market (“OTCQB”).  Upon the filing of the Company’s petition for voluntary relief under Chapter 11 of the United States Bankruptcy Code (as described below), the Company’s common and preferred stock were automatically removed from quotation on the OTCQB.  The Company’s common and preferred stock commenced trading on the OTC Pink Operated by the OTC Markets Group Inc. (also known as the “OTC Pink”) under the same symbols.

To address the foregoing concerns, the Company and its advisors have considered strategic alternatives for recommendation to the board of directors (the “Board”) of the Company.  In connection with developing and evaluating alternatives for the Board, the Company and its advisors engaged in a restructuring process to consider potential strategic transactions, including financing, refinancing, sale or merger transactions and encouraged proposals from existing stakeholders and interested third-parties.  The Company also elected to suspend its current operated drilling and development program in order to preserve capital for other cash needs including debt service while it considered other strategic alternatives or a possible restructuring of the Company’s debt and equity.    

On August 21, 2018, the Company publicly filed a process letter that again invited proposals and informed the public how any interested party could participate and make a proposal.  The process letter established the bid deadline of October 1, 2018 (the “Bid Deadline”).  The Company received three bids on the Bid Deadline, none of which provided a basis for repaying the Company’s indebtedness described below.  The Company’s Board determined that none of these proposals presented an actionable alternative.

In parallel with the foregoing marketing process, the Company engaged with funds affiliated with Ares regarding a comprehensive financial restructuring transaction.  On October 26, 2018, the Company entered into a restructuring support agreement (the “RSA”) with (i) AF V Energy I Holdings, L.P., an affiliate of Ares (the “Consenting Term Lender”) and party to the Third Amended and Restated Credit Agreement, dated March 3, 2017 (as amended, restated, modified, or supplemented form time to time, the “Term Loan”) (ii) certain holders affiliated with Ares (the “Consenting Noteholders”) of the Company’s Convertible Notes due 2022 (the “Notes”) issued pursuant to the indenture dated March 3, 2017 (as amended, restated, modified or supplemented from time to time, the “Indenture”), by and among the Company, as issuer, the guarantors specified therein and Wilmington Trust, National Association, as trustee (the “Trustee”) and collateral agent and (iii) certain holders affiliated with Ares (the “Ares Equity Holders” together with the Consenting Term Lender and the Consenting Noteholders, the “Consenting Parties”) of the Company’s outstanding shares of common stock (the “Existing Common Equity”), to support a restructuring (the “Restructuring”) on the terms set forth in the term sheet annexed to the RSA (the “Restructuring Term Sheet”).  The RSA contemplates that the Company and a subsidiary would file for voluntary relief under chapter 11 (the “Chapter 11 Cases”) of the United States Bankruptcy Code (the “Bankruptcy Code”) in a United States Bankruptcy Court (the “Bankruptcy Court”) to implement the Restructuring pursuant to a “prepackaged” plan of reorganization (the “Plan”) and the various related transactions set forth in or contemplated by the Restructuring Term Sheet, the DIP Term Sheet (defined below) and the Exit Facility Term Sheet (defined below).  Shortly after entering into the RSA, the Company commenced solicitation of the Plan consistent with section 1126(b) of the Bankruptcy Code, which solicitation concluded on October 30, 2018.    

8

On October 31, 2018 (the “Petition Date”), the Company and a subsidiary commenced chapter 11 proceedings and filed the Plan under Chapter 11 of the Bankruptcy Code in the Bankruptcy Court. The Company has filed a motion with the Bankruptcy Court seeking joint administration of their Chapter 11 Cases.  The Company will continue to operate its businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. The Company expects ordinary-course operations to continue substantially uninterrupted during and after the Chapter 11 Cases.

Pursuant to the terms of the RSA and the Restructuring Term Sheet, the Consenting Parties and other interest holders will receive treatment under the Plan summarized as follows:

• holders of claims under the DIP Facility (defined below) arising on account of the New Money Loans (defined below) will receive pro rata participation in the First Lien Exit Facility (defined below) in an amount equal to such claims arising on account of New Money Loans;  

• holders of claims under the DIP Facility, other than claims arising on account of the New Money Loans, will receive (a) pro rata participation in the Second Lien Exit Facility (defined below) up to an aggregate amount of $200.0 million and (b) to the extent any such claims exceed $200.0 million, such excess will receive a pro rata share of 100% of the common equity in the reorganized Company (the “New Common Equity”);

• holders of claims under the Term Loan will receive (a) to the extent there is remaining availability under the Second Lien Exit Facility, pro rata participation in the Second Lien Exit Facility in an equal face amount not to exceed $200.0 million and (b) to the extent any such claims remain outstanding, their pro rata share of 100% of the New Common Equity, subject to dilution upon the issuance of common stock upon exercise of the New Warrants described below and pursuant to a new management incentive plan to be entered into at the discretion of the board of the reorganized Company following emergence from bankruptcy (the “Management Incentive Plan”);

• holders of claims under the Indenture will receive their  pro rata share of 100% of the New Common Equity, subject to dilution upon the issuance of common stock upon exercise of the New Warrants described below and pursuant to the Management Incentive Plan;

• holders of claims arising out of any termination of the Company’s hedging or swap arrangements with Cargill, Inc. and NextEra Energy Marketing, LLC (collectively, the “Hedge Parties”) will receive payment in full in cash in monthly installments through December 2019 pursuant to new secured notes;

• holders of claims arising pursuant to statutory liens will receive payment in full in cash in two equal installments on the effective date of the Chapter 11 Cases and six months following such date;

• holders of claims arising from general unsecured obligations will receive payment in full in cash as set forth in the Plan;

• subject to certain conditions, including that such holders not seek official committee status or the appointment of a trustee or examiner, or object to or otherwise oppose the consummation of the Plan, holders of Gastar’s 8.625% Series A Cumulative Preferred Stock and 10.75% Series B Cumulative Preferred Stock (collectively, the “Existing Preferred Equity”) will receive their pro rata share based on their liquidation preference plus accumulated but unpaid dividends accrued through October 31, 2018 of warrants to purchase 2.5% of the New Common Equity; and

• subject to certain conditions, including that such holders not seek official committee status or the appointment of a trustee or examiner, or object to or otherwise oppose the consummation of the Plan, holders of the Existing Common Equity will receive their pro rata share of warrants to purchase 2.5% of the New Common Equity (together with the warrants listed in the previous bullet, the “New Warrants”).

In the event that a DIP Toggle Event (as defined in the Restructuring Term Sheet) has occurred, (i) holders of claims arising from general unsecured obligations will receive a pro rata share of the New Common Equity and (ii) all Existing Preferred Equity and Existing Common Equity and Subordinated Securities Claims will be canceled, released, and extinguished without distribution.  The occurrence of a DIP Toggle Event will not affect the other treatments contemplated by the RSA as listed above.

The RSA contains certain covenants on the part of each of the Company and the Consenting Parties, including limitations on the parties’ ability to pursue alternative transactions, commitments by the Consenting Parties to vote in favor of the Plan and commitments of the Company and the Consenting Parties to negotiate in good faith to finalize the documents and agreements governing the Plan. The RSA also provides for certain conditions to the obligations of the parties and for termination upon the

9

occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the RSA.

On October 26, 2018, the Company and the Hedge Parties entered into that certain Hedge Party Restructuring Support Agreement (the “Hedge Party RSA”).  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties described above.  The Hedge Party RSA contains certain covenants on the part of each of the Company and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements. The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, the Company with superpriority debtor-in-possession financing (the “DIP Facility”) on the terms set forth in the term sheet attached to the RSA (the “DIP Term Sheet”). The DIP Term Sheet provides that, among other things:

• the DIP Facility shall be comprised of term loans in an aggregate amount of approximately $383.9 million, consisting of $100 million of new money loans (the “New Money Loans”) and approximately $283.9 million of refinanced term loan obligations outstanding under the Term Loan;

• upon entry of and subject to a Bankruptcy Court order granting interim approval of the DIP Facility and subject to the satisfaction or waiver of additional conditions precedent, up to $15.0 million of the New Money Loans (the “Interim DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount that is not less than $2.5 million for the initial draw and not less than $500,000 for each subsequent draw (or, if less, the entire amount of the unused balance of the Interim DIP Tranche);

• upon entry of and subject to a Bankruptcy Court order granting final approval (the “Final Order”) of the DIP Facility, and subject to the satisfaction or waiver of additional conditions precedent and an approved budget, up to $100.0 million of New Money Loans, minus any amounts of New Money Loans previously drawn by the Company prior to such date (the resulting amount, the “Final DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Final DIP Tranche);

• upon entry of and subject to the Final Order and subject to the satisfaction or waiver of additional conditions precedent, including the Company having demonstrated to the reasonable satisfaction of the DIP Lenders acting in good faith, the bona fide need for additional liquidity to preserve lease operating rights in response to actions taken or proposed to be taken by third parties, an amount equal to $100.0 million minus the amount of New Money Loans previously drawn by the Company prior to such date (the resulting amount, the “Reserve DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Reserve DIP Tranche); and

• subject to entry of the Final Order, approximately $283.9 million in outstanding term loan obligations consisting of principal and accrued and unpaid interest under the Term Loan as of the date of the commencement of the Chapter 11 Cases will be refinanced by loans (not constituting New Money Loans) funded under the DIP Facility.

The Company’s entry into the DIP Facility has been approved by the Bankruptcy Court on an interim basis. The Company’s entry into the DIP Facility on a final basis will be considered by the Bankruptcy Court at a future date.  The foregoing description of the DIP Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the DIP Facility, as approved by the Bankruptcy Court.

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, the Company with an exit financing term loan facility (the “Exit Facility”) on the terms set forth in the term sheet attached to the RSA (the “Exit Facility Term Sheet”). The Exit Facility Term Sheet provides for, among other things, (a) a $100.0 million secured delayed draw term loan facility (the “First Lien Exit Facility”) comprised of (i) term loans consisting of New Money Loans funded under the DIP Facility and deemed funded under the First Lien Exit Facility on the effective date of the Plan and (ii) term loan commitments consisting of an amount equal to any undrawn commitment under the DIP Facility and (b) a secured term loan facility (the “Second Lien Exit Facility”) comprised of up to $200.0 million (as may be reduced by the Exit Lenders in their sole discretion on or prior to the effective date of the Plan), in aggregate principal amount of term loans deemed funded on the effective date of the Plan and consisting of DIP Claims and Term Loan Claims (each as defined in the RSA), as applicable (the loans under the First Lien Exit Facility and the Second Lien Exit Facility, collectively, the “Exit Loans”).  The Exit Loans may not be reborrowed once repaid.

10

The Exit Facility is subject to customary closing conditions and approval by the Bankruptcy Court, which has not been obtained at this time. The foregoing description of the Exit Facility Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the Exit Facility, as approved by the Bankruptcy Court.

The Company’s filing of its petition for voluntary relief under Chapter 11 of the Bankruptcy Code constitutes an event of default that accelerated the Company’s obligations under its Term Loan and its Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default.  The transactions described and contemplated by the Plan are all subject to the Bankruptcy Court approval at a future date.  There can be no assurances the Bankruptcy Court will ultimately approve the transaction as described above.

The Company intends to complete a supplemental marketing process seeking proposal for transactions that are higher and better than the transactions contemplated by the Plan during the Chapter 11 Cases, with a bid deadline of December 17, 2018.  The Company intends to publicly disclose further details regarding the supplemental marketing process, including informing interested parties how they may participate and make a proposal, at a future date.  In the absence of a higher or better proposal, the Company intends to seek confirmation of the Plan at a hearing currently scheduled for December 20, 2018.

Voluntary Reorganization Under Chapter 11

On October 31, 2018, the Company and its subsidiary (collectively, the “Debtors”) commenced Chapter 11 proceedings and filed the Plan for reorganization under Chapter 11 of the Bankruptcy Code with the Bankruptcy Court for the Southern District of Texas.  The Debtors have filed a motion with the Bankruptcy Court seeking joint administration of their Chapter 11 Cases under the caption In re: Gastar Exploration Inc., et al.

Subject to certain exceptions, under the Bankruptcy Code, the filing of the petitions for voluntary relief in the Chapter 11 Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover, collect or secure a claim arising prior to the date of the filing of the petitions.  Accordingly, although the filing of the voluntary petitions triggered defaults on the Debtors’ debt obligations, creditors are stayed from taking any actions against the Debtors as a result of such defaults, subject to certain limited exceptions permitted by the Bankruptcy Code.  Absent an order of the Bankruptcy Court, substantially all of the Debtors’ pre-petition liabilities are subject to settlement under the Bankruptcy Code.

For the duration of the Chapter 11 Cases, the Company’s operations and ability to develop and execute its business plan are subject to the risks and uncertainties associated with the Chapter 11 process.  As a result of these risks and uncertainties, the number of the Company’s shares of common stock and stockholders, assets, liabilities, officers and/or directors could be significantly different following the outcome of the Chapter 11 Cases, and the description of the Company’s operations, properties and capital plans included in this quarterly report may not accurately reflect its operations, properties and capital plans following the Chapter 11 process.

In particular, subject to certain exceptions, under the Bankruptcy Code, the Debtors may assume, assign or reject certain executory contracts and unexpired leases subject to the approval of the Bankruptcy Court and certain other conditions.  Generally, the rejection of an executory contract or unexpired lease is treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves the Debtors of performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed breach.  Counterparties to such rejected contracts or leases may assert unsecured claims in the Bankruptcy Court against the applicable Debtors’ estate for such damages.  Generally, the assumption of an executory contract or unexpired lease requires the Debtors to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance.  Accordingly, any description of an executory contract or unexpired lease with the Debtor in this quarterly report, including where applicable a quantification of the Company’s obligations under any such executory contract or unexpired lease with the Debtor is qualified by any overriding rejection rights the Company has under the Bankruptcy Code.  Further, nothing herein is or shall be deemed an admission with respect to any claim amounts or calculations arising from the rejection of any executory contract or unexpired lease and the Debtors expressly preserve all of their rights with respect thereto.

Although the Company intends to pursue the restructuring in accordance with the terms set forth in the Plan and the RSA, the transactions necessary to implement that restructuring are subject to, among other things, Bankruptcy Court approval, and there can be no assurance that the Company will be successful in completing a restructuring or any other similar transaction on the terms set forth in the Plan and the RSA, on different terms or at all.  

Furthermore, although the Company will continue to operate its businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court, these factors raise substantial doubt about the Company’s ability to continue as a going concern.  These unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of the

11

going concern uncertainty.  If the Company cannot continue as a going concern, adjustments to the carrying values and classification of its assets and liabilities and the reported amounts of income and expenses could be required and could be material.

3. Summary of Significant Accounting Policies

The accounting policies followed by the Company are set forth in the notes to the Company’s audited consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2017 (the “2017 Form 10-K”) filed with the SEC. Please refer to the notes to the consolidated financial statements included in the 2017 Form 10-K for additional details of the Company’s financial condition, results of operations and cash flows. No material item included in those notes has changed except as a result of normal transactions in the interim or as disclosed within this report.

The unaudited interim condensed consolidated financial statements of the Company included herein are stated in U.S. dollars and were prepared from the records of the Company by management in accordance with U.S. GAAP applicable to interim financial statements and reflect all normal and recurring adjustments, which are, in the opinion of management, necessary to provide a fair presentation of the results of operations and financial position for the interim periods. Such financial statements conform to the presentation reflected in the 2017 Form 10-K except for revenue which, for the three and nine months ended September 30, 2018, is presented net of treating, transportation and gathering costs pursuant to current authoritative accounting guidance. The current interim period reported herein should be read in conjunction with the financial statements and accompanying notes, including Item 8. “Financial Statements and Supplementary Data, Note 3 – Summary of Significant Accounting Policies,” included in the 2017 Form 10-K.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates with regard to these financial statements include the valuation of convertible debt, estimate of proved oil and natural gas reserve quantities and the related present value of estimated future net cash flows.

The unaudited interim condensed consolidated financial statements of the Company include the consolidated accounts of all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018.

Subsequent Events

In preparing these financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued and has disclosed certain subsequent events in these condensed consolidated financial statements, as appropriate.

Restricted Cash

Cash and cash equivalents that are restricted as to withdrawal or use under the terms of certain contractual agreements are recorded in restricted cash in the current assets section of our consolidated balance sheet.  At September 30, 2018 and December 31, 2017, the Company had restricted cash of $25,000 and $370,000, respectively.

Accounts Receivable

Accounts receivable are reported net of the allowance for doubtful accounts.  The allowance for doubtful accounts is determined based on a review of the Company’s receivables.  Receivable accounts are charged off when collection efforts have failed or the account is deemed uncollectible.  During 2016, the Company determined that a receivable account from a third-party natural gas and NGLs purchaser would no longer be collectible as a result of the third-party purchaser filing for bankruptcy.  A summary of the activity related to the allowance for doubtful accounts is as follows:

12

	September 30, 2018		December 31, 2017
	(in thousands)
Allowance for doubtful accounts, beginning of period	$	1,953	$	1,953
Expense		—		—
Reductions/write-offs		—		—
Allowance for doubtful accounts, end of period	$	1,953	$	1,953

Recent Accounting Developments

Leases.  In February 2016, the FASB issued updated guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and enhance disclosures regarding key information about leasing arrangements.  Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Additionally, in January 2018, the FASB issued an amendment to the updated guidance to permit an entity to elect an optional transition practical expedient to not evaluate under the new guidance land easements that exist or expire before the adoption of the updated guidance and that were not previously accounted for as leases under previous guidance.  In July 2018, the FASB issued an additional amendment that permits an entity to elect an additional transition method to the existing modified retrospective transition requirements.  Under the new transition method, an entity could adopt the provisions of this update by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption.  Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard may continue to be in accordance with the previous lease guidance.  This amendment also allows a practical expedient that permits lessors to not separate non-lease components from the associated lease component if certain conditions are present. The amendments in this update are effective beginning on January 1, 2019 and should be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements.  Early adoption is permitted.  The Company has commenced analyzing its lease contracts but has not yet determined what the effects of adopting this updated guidance will be on its consolidated financial statements.  The Company will adopt this updated guidance in the first quarter 2019 and anticipates that it will recognize a right of use asset and lease liability on the adoption date. The Company plans to apply practical expedients provided in the standards update that allow, among other things, not to reassess contracts that commenced prior to the adoption. The Company also anticipates electing a policy not to recognize right of use assets and lease liabilities related to short-term and immaterial leases.

Revenue Recognition.  On January 1, 2018, the Company adopted Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“ASC 606”) using the modified retrospective method of transition.  Under the modified retrospective approach, the standard has been applied to all existing contracts as of the date of initial application with the cumulative effect of applying the standard, if any, recognized in retained earnings.  

The impact of adoption on our current period results is as follows:

	Three Months Ended September 30, 2018							Nine Months Ended September 30, 2018
	Under ASC 606		Under ASC 605		Increase (Decrease)			Under ASC 606		Under ASC 605		Increase (Decrease)
	(in thousands)							(in thousands)
Revenues:
Oil and condensate	$	17,436	$	17,448	$	(12	)	$	54,497	$	54,530	$	(33	)
Natural gas		1,986		2,752		(766	)		5,618		7,708		(2,090	)
NGLs		2,092		2,593		(501	)		7,315		8,629		(1,314	)
Total oil and condensate, natural gas and NGLs revenues	$	21,514	$	22,793	$	(1,279	)	$	67,430	$	70,867	$	(3,437	)
Expenses:
Transportation, treating and gathering	$	—	$	1,279	$	(1,279	)	$	—	$	3,437	$	(3,437	)
Net income (loss)	$	21,514	$	21,514	$	—		$	67,430	$	67,430	$	—
Retained earnings	$	21,514	$	21,514	$	—		$	67,430	$	67,430	$	—

The primary impact to our revenues as a result of the adoption of ASC 606 is the recording of transportation, treating, gathering and compression expenses (“Post-Production Expenses”) as a direct reduction to revenues instead of our historical practice

13

of presenting such expenses gross in transportation, treating and gathering.  These changes are due to the conclusion that the Company represents the agent in the sale of natural gas and NGLs under its gas processing and marketing agreements with midstream entities in accordance with the control model in ASC 606.  As a result, the Company is required to record revenue on a net basis for amounts expected to be received from third-party customers through the marketing process, with Post-Production Expenses incurred subsequent to control of the product(s) transferring to the midstream entity at the wellhead being netted against revenue.

4. Property, Plant and Equipment

The amount capitalized as oil and natural gas properties was incurred for the purchase and development of various properties in the U.S., specifically in the State of Oklahoma.  

The following table summarizes the components of unproved properties excluded from amortization at the dates indicated:

	September 30, 2018		December 31, 2017
	(in thousands)
Unproved properties, excluded from amortization:
Drilling in progress costs	$	800	$	4,772
Acreage acquisition costs		122,455		113,191
Capitalized interest		21,131		13,992
Total unproved properties excluded from amortization	$	144,386	$	131,955

The full cost method of accounting for oil and natural gas properties requires a quarterly calculation of a limitation on capitalized costs, often referred to as a full cost ceiling calculation. The ceiling is the present value (discounted at 10% per annum) of estimated future cash flow from proved oil, condensate, natural gas and NGLs reserves reduced by future operating expenses, development expenditures, abandonment costs (net of salvage) to the extent not included in oil and natural gas properties pursuant to authoritative guidance and estimated future income taxes thereon. To the extent that the Company's capitalized costs (net of accumulated depletion and deferred taxes) exceed the ceiling at the end of each reporting period, the excess must be written off to expense for such period. Once incurred, this impairment of oil and natural gas properties is not reversible at a later date even if oil and natural gas prices increase. The ceiling calculation is determined using a mandatory trailing 12-month unweighted arithmetic average of the first-day-of-the-month commodities pricing and costs in effect at the end of the period, each of which are held constant indefinitely (absent specific contracts with respect to future prices and costs) with respect to valuing future net cash flows from proved reserves for this purpose.  The 12-month unweighted arithmetic average of the first-day-of-the-month commodities prices are adjusted for basis and quality differentials in determining the present value of the proved reserves.  The table below sets forth relevant pricing assumptions utilized in the quarterly ceiling test computations for the respective periods noted before adjustment for basis and quality differentials:

	2018
	Total Year to Date Impairment		September 30		June 30		March 31
Henry Hub natural gas price (per MMBtu)(1)			$	2.91	$	2.92	$	3.00
WTI oil price (per Bbl)(1)			$	63.43	$	57.67	$	53.49
Impairment recorded (pre-tax) (in thousands)	$	17,993	$	—	$	17,993	$	—

	2017
	Total Year to Date Impairment		September 30		June 30		March 31
Henry Hub natural gas price (per MMBtu)(1)			$	3.00	$	3.01	$	2.73
WTI oil price (per Bbl)(1)			$	49.81	$	48.95	$	47.61
Impairment recorded (pre-tax) (in thousands)	$	—	$	—	$	—	$	—

(1) For the respective periods, oil and natural gas prices are calculated using the trailing 12-month unweighted arithmetic average of the first-day-of-the-month prices based on Henry Hub spot natural gas prices and WTI spot oil prices.

The Company could potentially incur additional ceiling test impairments in the future should commodities prices decline or the value of its estimates of proved reserves declines. However, it is difficult to project future impairment charges in light of numerous variables involved.

14

The Company’s proved reserves estimates and their estimated discounted value and standardized measure will also be impacted by changes in lease operating costs, future development costs, production, exploration and development activities and estimated future income taxes.  The ceiling limitation calculation is not intended to be indicative of the fair market value of the Company’s proved reserves or future results.

The Company’s undeveloped reserves previously classified as proved, other than the PUD reserves associated with certain wells developed prior to June 30, 2018 or in the process of drilling and completion at June 30, 2018, were reclassified as unproved at June 30, 2018 due to the inability to meet the reasonable certainty criteria for proved reserves, as prescribed under the SEC rules, primarily due to the uncertainties regarding the availability and timing of funds required to develop these reserves.  As of September 30, 2018, the Company has no PUD reserves since all prior PUD reserves recognized at June 30, 2018 have been converted to proved developed.  

WEHLU Sale

On January 23, 2018, the Company entered into a definitive agreement of sale and purchase (the “Sale Agreement”) to divest its interest in the West Edmund Hunton Lime Unit (“WEHLU”) and adjacent undeveloped acreage to Revolution Resources, LLC, for $107.5 million, subject to, among other customary adjustments, adjustments for a property sale effective date of October 1, 2017 (the “WEHLU Sale”).  Pursuant to the Sale Agreement, the WEHLU Sale closed on February 28, 2018.  After effective date and other adjustments of approximately $9.9 million primarily related to revenues and direct operating expenses, net cash proceeds from the WEHLU Sale were approximately $97.6 million.  The WEHLU Sale was reflected as a reduction to the full cost pool and no gain or loss was recorded related to the divestiture as such divestiture did not result in a significant change to the depletion rate.

The following unaudited pro forma results for the three months ended September 30, 2017 and the nine months ended September 30, 2018 and 2017 show the effect on the Company's consolidated results of operations as if the WEHLU Sale had occurred at the beginning of the periods presented.  The pro forma results are the result of excluding from the statement of operations of the Company the revenues and direct operating expenses for the properties divested adjusted for (1) the reduction in asset retirement obligation liabilities and accretion expense for the properties divested and (2) the reduction in depreciation, depletion and amortization expense as a result of the divestiture.  As a result, certain estimates and judgments were made in preparing the pro forma adjustments.

STACK Leasehold Acquisition

On March 22, 2017, the Company completed the acquisition of additional working and net revenue interests in approximately 66 gross (9.5 net) producing wells and 5,670 net acres of additional undeveloped STACK Play leasehold in Kingfisher County, Oklahoma, effective March 1, 2017, for $51.4 million (the “STACK Leasehold Acquisition”).  Prior to the completion of the STACK Leasehold Acquisition, the Company held an interest in the majority of acquired producing wells and acreage.  The Company accounted for the STACK Leasehold Acquisition as an asset acquisition.  

15

Development Agreement

On October 14, 2016, the Company executed an agreement with STACK Exploration LLC (the “Investor”) (the “Development Agreement”) to jointly develop up to 60 Gastar operated wells in the STACK Play in Kingfisher County, Oklahoma (the “Drilling Program”).  The Drilling Program targeted the Meramec and Osage formations within the Mississippi Lime in a contract area within three townships covering approximately 32,900 gross (21,200 net) undeveloped mineral acres under leases held by the Company. The Company serves as the operator of all Drilling Program wells.      

Under the Development Agreement, the Investor funded 90% of the Company’s working interest portion of drilling and completion costs to initially earn 80% of the Company’s working interest in each new well (in each case, proportionately reduced by other participating working interests in the well).  As a result, the Company paid 10% of its working interest portion of such costs for 20% of its original working interest.  

The proposed Drilling Program wells were to be mutually developed in three tranches of 20 wells each.  The locations of the first 20 wells, comprised of 18 Meramec formation wells and two Osage formation wells, were mutually agreed upon by the Company and the Investor.   Participation in the second tranche of 20 Drilling Program wells was to be at the election of the Investor and the third tranche of 20 wells would require mutual consent.  On July 31, 2017, the Investor elected not to participate in the second tranche of wells.  With respect to each 20-well tranche, when the Investor has achieved an aggregate 15% internal rate of return for its investment in the tranche, Investor’s interest will be reduced from 80% to 40% of the Company’s original working interest and the Company’s working interest increases from 20% to 60% of the original working interest.  When a tranche internal rate of return of 20% is achieved by the Investor, Investor’s working interest decreases to 10% and the Company’s working interest increases to 90% of the working interest originally owned by the Company. 

If and when the final reversion of working interest in the completed 20 well tranche should occur, the Investor has the right, but not the obligation, for a period of six months to cause the Company to purchase the Investor’s remaining interest in the 20 wells in the Drilling Program (the “WI Tail”) for such tranche (the “Investor Put Right”) for fair market value by applying the methodology to determine a 15% discounted present value as defined by the Development Agreement.  If the Investor fails to exercise the Investor Put Right within the six-month period after achieving final reversion, then for a period of six months thereafter, the Company shall have the right, but not the obligation, to purchase the WI Tail from the Investor on the same fair market value approach of the Investor Put Right.  If final reversion has not been achieved by August 19, 2024, Investor will, for a period of six months thereafter, have the right to cause the Company to buy Investor’s then-current interest in the Drilling Program wells at an agreed upon valuation.  Based on current commodity prices, well cost and production performance of the completed wells drilled in the first tranche, the 15% of internal rate of return is not anticipated to be achieved.  

By December 31, 2017, the Company and the Investor had completed all 20 gross (15.8 net; 3.2 net to the Company) wells within the first tranche of the Drilling Program.

16

(1) Pursuant to Amendment No. 2 (as defined below), the Company can elect to pay in kind 100% of the interest due after June 30, 2017 to December 31, 2018.  The Company elected to pay in kind 100% of the interest due for the period June 30, 2017 to July 2, 2018 in the amount of $26.8 million, thus increasing the outstanding principal balance of the Term Loan to $276.8 million.  The Company elected to pay in kind 100% of the interest due for the period July 2, 2018 to September 30, 2018 in the amount of $7.0 million and such was accrued at September 30, 2018 due to the interest payment date falling on a weekend outside of quarter end.    

Ares Investment Transactions

On March 3, 2017, certain funds (the “Purchasers”) managed indirectly by Ares purchased from the Company for cash (i) $125.0 million aggregate principal amount of its Notes sold at par, which Notes, subject to the receipt of approval of the Company’s stockholders which was obtained on May 2, 2017, are convertible into common stock or, in certain circumstances, cash in lieu of common stock or a combination of cash and shares of common stock as described below and (ii) 29,408,305 shares of common stock for a purchase price of $50.0 million at a purchase price of $1.7002 per share based on a 30-trading day volume weighted average price (“VWAP”) determined on February 15, 2017.  In addition, an affiliate of Ares concurrently loaned the Company $250.0 million pursuant to the Term Loan, as borrower, the guarantors party thereto, AF V Energy I Holdings, L.P., a fund managed indirectly by Ares Management LLC, as lender, and Wilmington Trust, National Association, as Administrative Agent as further described below.  The proceeds from the sale of the Notes, the common stock and the Term Loan were used to fully repay and redeem the Company’s prior Revolving Credit Facility (as defined below) and to satisfy and discharge its $325.0 million of 8.625% senior secured notes due May 2018, which were satisfied and discharged on March 3, 2017 by irrevocably calling for redemption and depositing with the indenture trustee cash in the amount of the redemption price of 102.156% of their principal amount plus accrued and unpaid interest to the redemption date of March 24, 2017, and to pay the expenses from the Ares transactions.  

In order to provide funding for the STACK Leasehold Acquisition and a portion of the Company’s 2017 capital budget, on March 21, 2017, the Purchasers purchased from the Company for cash an additional $75.0 million aggregate principal amount of its Notes sold at par (the “Additional Notes”).  

The Notes, including the Additional Notes, were issued with conversion rights that were subject to the approval of holders of issued and outstanding common stock (other than the Purchasers), which approval was obtained May 2, 2017 (the “Requisite Stockholder Approval”).  Pursuant to the purchase agreement for the Additional Notes, upon receipt of Requisite Stockholder Approval, Purchasers and the Company exchanged $37.5 million principal amount of the Additional Notes for (a) 25,456,521 newly issued shares of common stock (the “Repurchase Shares”) and (b) 2,000 shares of the Company’s Special Voting Preferred Stock, par value $0.01 per share (the “Mandatory Repurchase”).  The terms of Mandatory Repurchase, which was effected May 5, 2017, provided for one Repurchase Share issued for each $1.4731 of outstanding principal of the repurchased Notes, which was based on the 10-day VWAP of the common stock for the period ended March 17, 2017.  The exchange reduced the aggregate principal amount of issued and outstanding Notes from $200.0 million to $162.5 million at June 30, 2017, which principal amount remained outstanding at September 30, 2018.

Term Loan

On March 3, 2017, the Company entered into a credit agreement for the Term Loan. The Term Loan bears interest at a per annum rate equal to 8.5%, payable on a quarterly basis on each March 31, June 30, September 30 and December 31 of each year, commencing March 31, 2017.  The Term Loan has a scheduled maturity of March 3, 2022.  In addition, prepayment of the Term Loan is subject to an interest “make-whole” and prepayment premium, such that any prepayment of the loans thereunder prior to the stated maturity date shall be subject to the payment of a prepayment premium, and depending on the date of such prepayment, the applicable interest “make-whole” amount, with the amount of such prepayment premium decreasing over the life of the Term Loan.  

The Term Loan is guaranteed by the Company’s sole domestic subsidiary and will be guaranteed by all of the Company's future domestic subsidiaries formed during the term of the Term Loan. The Term Loan is secured by a first-priority lien on substantially all of the assets of the Company and its subsidiaries, excluding certain assets as customary exceptions.

The Term Loan contains various customary covenants for credit facilities of this type, including, among others, restrictions on granting liens, incurrence of other indebtedness, payments of certain dividends and other restricted payments, engaging in transactions with affiliates, dispositions of assets and other, in each case subject to certain baskets and exceptions.    

All outstanding amounts owed become due and payable upon the occurrence of certain usual and customary events of default, including among others (i) failure to make payments; (ii) non-performance of covenants and obligations continuing beyond any applicable grace period; and (iii) the occurrence of a change in control of the Company, as defined in the Term Loan.  As of September 30, 2018, no events of default had occurred.

17

The Company’s voluntary filing of its petition in the Chapter 11 Cases on October 31, 2018 constituted an event of default that accelerated the Company’s obligations under the Term Loan.  Under the Bankruptcy Code, the creditors under the Term Loan and other debt agreements are stayed from taking any action against the Company as a result of an event of default.  See Note 2 – Going Concern for additional information about the Chapter 11 Cases and the proposed Plan.

The Company accounted for the Term Loan in accordance with guidance relating to “Debt with Conversion and Other Options” which indicates that when multiple securities are issued in a single transaction, total proceeds should be allocated based on the relative fair values of each instrument, assuming no instrument is subsequently required to be recorded at fair value.  The fair value of the Term Loan at the date of issuance was determined to be at a discounted $224.8 million based on the fair value of similar debt instruments.  The $25.2 million debt discount related to the Term Loan was initially recorded as a reduction to the Term Loan liability and as additional paid-in capital on the Company’s consolidated balance sheet.  The $5.5 million of issuance costs associated with the Term Loan are recorded as a reduction to the Term Loan liability.  Both the debt discount and issuance costs will be amortized over the life of the Term Loan using the effective interest method.  The effective interest rate for the Term Loan is approximately 13.0% per annum.

On March 20, 2017, the Company, together with the parties thereto, entered into Amendment No. 1 to the Term Loan credit agreement which amendment permitted the issuance of the Additional Notes.  

On August 2, 2017, the Company, together with the parties thereto, entered into an Amendment No. 2 to Term Loan credit agreement (“Amendment No. 2”).  Amendment No. 2 amended the Term Loan, to among other things, (i) allow for the payment of pay in kind (“PIK”) interest on the Term Loan at the applicable PIK percentage and (ii) increased the applicable interest rate for periods ending after June 30, 2017 from 8.5% per annum to 10.25% per annum.  Amendment No. 2 allows the Company to elect to PIK upon proper notice 100% of interest payments due after June 30, 2017 and prior to December 31, 2018 and at the Company’s election, PIK between 0% and 50% of any interest payments occurring after December 31, 2018 (other than interest due on the maturity date or the date of any repayment or prepayment).  The Term Loan interest rate increased from 8.5% per annum to 10.25% per annum for all interest periods post June 30, 2017 and the PIK interest shall be payable by capitalizing and adding such amounts to the outstanding principal amount of the Term Loan on the applicable interest payment date.

On September 18, 2017, the Company, together with the parties thereto, entered into Amendment No. 3 to the Term Loan credit agreement (“Amendment No. 3”).  Amendment No. 3 amended the Term Loan to, among other things, expressly provide that certain assignments of oil and natural gas properties made or to be made by the Company to Red Bluff Resources Operating, LLC (“Red Bluff”), pursuant to the Red Bluff Purchase and Sale Agreement dated October 19, 2016 between the Company and Red Bluff (“Red Bluff PSA”), are permitted by the Term Loan and are not subject to the mandatory prepayment provisions applicable to “Asset Sales” under the Term Loan.

On June 29, 2018, the Company, together with the parties thereto, entered into Amendment No. 4 to the Term Loan credit agreement (“Amendment No. 4”).  Amendment No. 4, among other things, (i) reduced the period the Company could cure a default resulting from the failure to comply with certain covenants applicable to the Term Loan from 30 days to 15 days, (ii) waived certain defaults under the Term Loan and (iii) prohibited the Company from making cash dividends or distributions on or with respect to its capital stock, other than cash dividends on its Series A Preferred Stock and Series B Preferred Stock declared for the month of June 2018.              

The carrying amounts of the Term Loan for the periods indicated are as follows:

	September 30, 2018			December 31, 2017
	(in thousands)
Term Loan, principal balance(1)	$	276,778		$	256,599
Less:
Unamortized deferred financing costs		(4,002	)		(4,724	)
Unamortized debt discount		(19,873	)		(22,464	)
Term loan, net	$	252,903		$	229,411

18

(1) Pursuant to Amendment No. 2, the Company can elect to pay in kind 100% of the interest due after June 30, 2017 to December 31, 2018.  The Company elected to pay in kind 100% of the interest due for the period June 30, 2017 to July 2, 2018 in the amount of $26.8 million, thus increasing the outstanding principal balance of the Term Loan to $276.8 million.  The Company elected to pay in kind 100% of the interest due for the period July 2, 2018 to September 30, 2018 in the amount of $7.0 million and such was accrued at September 30, 2018 due to the interest payment date falling on a weekend outside of quarter end.  

Indenture and Notes

The principal terms of the Notes are governed by the Indenture. Pursuant to the Indenture, the Notes were issued for cash at par, bear interest at 6.0% per annum and will mature on March 1, 2022, unless earlier repurchased, redeemed or converted in accordance with the terms of the Indenture. Interest is payable on the Notes on each March 1, June 1, September 1 and December 1 of each year, commencing on June 1, 2017.  

Pursuant to the Indenture, Requisite Stockholder Approval was required on or before July 3, 2017 to approve the conversion rights of the Notes (including the Additional Notes) to be convertible at the option of the holder into shares of common stock based on the terms of the Indenture.  Requisite Stockholder Approval was obtained on May 2, 2017 at a special meeting of stockholders.  

The interest rate on the Notes was subject to an increase in certain circumstances if the Company fails to comply with certain obligations under a Registration Rights Agreement and on the Notes in the case of certain issuances of common stock by the Company at a price below $1.7002 per share (subject to adjustment).

The Notes are secured by a second-priority lien on substantially all of the assets of the Company and its sole subsidiary. If at least a majority of the Notes issued pursuant to the Securities Purchase Agreement dated February 16, 2017 (the “Purchase Agreement”) cease to be held by affiliates of Ares as provided in the Indenture, the liens securing the Notes will be released and substantially all of the restrictive covenants in the Indenture will terminate.  

The Indenture restricts the ability of the Company and certain of its subsidiaries to, among other things: (i) pay dividends or make other distributions in respect of the Company’s capital stock or make other restricted payments; (ii) incur additional indebtedness and issue preferred stock; (iii) make certain dispositions and transfers of assets; (iv) engage in transactions with affiliates; (v) create liens; (vi) engage in certain business activities that are not related to oil and gas; and (vii) impair any security interest. These covenants are subject to a number of exceptions and qualifications. 

The Indenture provides that a number of events will constitute an Event of Default (as defined in the Indenture), including, among other things: (i) a failure to pay the Notes when due at maturity, upon redemption or repurchase; (ii) failure to pay interest for 30 days; (iii) the Company’s failure to deliver certain notices; (iv) a default in the Company’s obligation to convert the Notes; (v) the Company’s failure to comply with certain covenants relating to merger, consolidation or sale of assets; (vi) the Company’s failure to comply, for 60 days following notice, with any of the other covenants or agreements in the Indenture; (vii) a default, which is not cured within 30 days, by the Company or any Restricted Subsidiaries (as defined in the Indenture) with respect to any mortgages or any indebtedness for money borrowed of at least $15 million; (viii) one or more final judgments against the Company or any of its Restricted Subsidiaries for the payment of at least $15 million; (ix) the Company’s failure to make any payments required under that certain development agreement, which is not cured within 30 days; (x) causing any Guarantee (as defined in the Indenture) to cease to be in full force and effect; (xi) the cessation to be in full force and effect of any of the collateral agreements entered into with respect to the Notes; and (xii) certain events of bankruptcy or insolvency. In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.  At September 30, 2018, no Event of Default had occurred.     

The Company’s voluntary filing of its petition in the Chapter 11 Cases on October 31, 2018 constituted an event of default that accelerated the Company’s obligations under the Notes.  Under the Bankruptcy Code, the creditors under the Notes and other debt agreements are stayed from taking any action against the Company as a result of an event of default.  See Note 2 – Going Concern for additional information about the Chapter 11 Cases and the proposed Plan.

On June 29, 2018, the Company, the subsidiary guarantor named therein and the Trustee, entered into a Second Supplemental Indenture (the “Second Supplemental Indenture”), which supplements the Indenture.  The Second Supplemental Indenture, among other things, (i) waived certain defaults, (ii) reduced the period the Company could cure certain covenant defaults under the Indenture from 60 days to 15 days and (iii) prohibited the Company and its subsidiary from making cash dividends or distributions on or with respect to its capital stock, other than cash dividends on its Series A Preferred Stock and its Series B Preferred Stock declared for the month of June 2018.

19

In accordance with accounting guidance relating to “Debt with Conversion and Other Options” which indicates that when multiple securities are issued in a single transaction, total proceeds should be allocated based on the relative fair values of each instrument, assuming no instrument is subsequently required to be recorded at fair value.  The Company accounted for the Notes based on their relative fair value to the bundled transaction and subsequently separately accounted for the liability and equity conversion components of the Notes due to the Company’s option to settle the conversion obligation in cash.  The fair value of the debt portion of the Notes, excluding the conversion feature, at the dates of issuance was estimated to be approximately $147.8 million and was calculated based on the fair value of similar non-convertible debt instruments in conjunction with the relative fair value of the Term Loan issued on the same date.  As a result of such valuation, a debt discount of $52.4 million related to the Notes was recorded.  Additionally, the value of the conversion option at the dates of issuance was calculated to be $77.6 million based on the residual fair value after application of such to the debt and was recorded as additional paid-in capital on the Company’s condensed consolidated balance sheet.  Total debt issuance costs related to the Notes were $5.4 million, of which $3.2 million was allocated to the liability component of the Notes and $2.2 million to the equity component of the Notes.  The debt discount and the liability component of the debt issuance costs will be amortized over the term of the Notes.  The weighted average effective interest rate used to amortize the debt discount and the liability component of the debt issue costs for the Notes is approximately 16% based on the Company’s estimated non-convertible borrowing rate as of the date the Notes were initially issued.  

The carrying amount of the liability component of the Notes for the periods indicated are as follows:

	September 30, 2018			December 31, 2017
	(in thousands)
Notes, principal balance	$	162,500		$	162,500
Less:

Notes, net	$	120,258		$	113,541

The carrying amount of the equity components of the Notes recorded in additional paid in capital for the periods indicated are as follows:

	September 30, 2018			December 31, 2017
	(in thousands)
Value of conversion option	$	77,626		$	77,626

Second Amended and Restated Revolving Credit Facility

On June 7, 2013, the Company entered into the Second Amended and Restated Credit Agreement among the Company, Wells Fargo Bank, National Association, as Administrative Agent, Collateral Agent, Swing Line Lender and Issuing Lender and the lenders named therein (the “Revolving Credit Facility”).   The Revolving Credit Facility had a scheduled maturity of November 14, 2017.

On January 10, 2017, the Company, together with the parties thereto, entered into an amendment to the Second Amended and Restated Credit Agreement (“Amendment No. 10”), which amended the Revolving Credit Facility to, among other things, permit the payment of certain cash dividends on its preferred stock, including the dividends declared payable on January 31, 2017, provided that (i) the Company’s borrowing base was correspondingly reduced in the amount of any such dividend payment and (ii) the Company paid down its outstanding indebtedness under the Revolving Credit Facility in the amount of any resulting borrowing base deficiency.

Under Amendment No. 10, payment of the declared January 2017 dividend and monthly preferred stock cash dividends through May 2017 was permitted contingent upon the satisfaction of certain conditions, including but not limited to, (i) the absence of any defaults or borrowing base deficiency, (ii) for any dividends declared and paid in respect of April 2017 and May 2017, having cash liquidity (including any available borrowings under the Revolving Credit Facility) of more than $30.0 million and (iii) paying any permitted dividends solely from proceeds received by the Company from sales of equity since November 30, 2016 (including through the Company’s at-the-market issuance sales agreement with a third-party sales agent to sell, from time to time, shares of the Company’s common stock (the “ATM Program”).  Under Amendment No. 10, the Company also agreed to pay down indebtedness under its Revolving Credit Facility by at least an additional $8.1 million by April 30, 2017.  

20

On March 3, 2017, the Company used a portion of the net proceeds from the transactions described in this Note 5 under the caption “Ares Investment Transactions” above to fully repay all of the $69.2 million borrowings outstanding under the Revolving Credit Facility (which was terminated on such date).

Senior Secured Notes

At December 31, 2016, the Company had $325.0 million aggregate principal amount of 8 5/8% Senior Secured Notes due May 15, 2018 (the “Former Notes”) outstanding under an indenture by and among the Company, the Guarantors named therein (the “Guarantors”), Wells Fargo Bank, National Association, as Trustee (in such capacity, the “Former Notes Trustee”) and Collateral Agent.  The Former Notes bore interest at a rate of 8.625% per year, payable semi-annually in arrears on May 15 and November 15 of each year.  

On March 3, 2017, the redemption price plus interest on all of the Company’s outstanding $325.0 million principal of the Former Notes was funded to satisfy and discharge the Former Notes from a portion of the net proceeds from the transactions described in this Note 5 under the caption “Ares Investment Transactions” above.  All of the Former Notes were satisfied and discharged on March 3, 2017 by irrevocably calling for redemption and depositing with the indenture trustee cash in the amount of the redemption price of 102.156% of  the principal amount, or principal plus an additional $7.0 million, plus accrued and unpaid interest to the redemption date of March 24, 2017.  Additionally, the Company wrote-off $5.2 million of remaining unamortized deferred financing costs related to the Former Notes upon redemption.    

6. Fair Value Measurements

The Company’s financial assets and liabilities are measured at fair value on a recurring basis. The Company discloses its recognized non-financial assets and liabilities, such as asset retirement obligations, unproved properties and other property and equipment, at fair value on a non-recurring basis. For non-financial assets and liabilities, the Company is required to disclose information that enables users of its financial statements to assess the inputs used to develop these measurements. The Company assesses its unproved properties for impairment whenever events or circumstances indicate the carrying value of those properties may not be recoverable.  The fair value of the unproved properties is measured using an income approach based upon internal estimates of future production levels, current and future prices, drilling and operating costs, discount rates, current drilling plans and favorable and unfavorable drilling activity on the properties being evaluated and/or adjacent properties, which are Level 3 (as defined below) inputs.  Should an impairment of unproved properties occur, the value of the impaired properties would be reclassified into proved properties in the full cost pool subject to depletion.  As no other fair value measurements are required to be recognized on a non-recurring basis at September 30, 2018, no additional disclosures are provided.

As defined in the guidance, fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). To estimate fair value, the Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. The Company’s cash equivalents consist of short-term, highly liquid investments, which have maturities of 90 days or less, including sweep investments and money market funds.

• Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

• Level 3 inputs are measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources. These inputs may be used with internally developed methodologies or third party broker quotes that result in management’s best estimate of fair value. The Company’s valuation models consider various inputs including (a) quoted forward prices for commodities, (b) time value, (c) volatility factors and (d) current market and contractual prices for the underlying instruments. Significant increases or decreases in any of these inputs in isolation would result in a significantly higher or lower fair value measurement.  Level 3 instruments are commodity costless collars, index swaps, basis and fixed price swaps and put and call options to hedge oil, natural gas and NGLs price risk. At each balance sheet date, the Company performs an analysis of all applicable instruments and includes in Level 3 all of those whose fair value is based on significant unobservable inputs.  The fair values derived from counterparties and third-party brokers are verified by the Company using publicly available values for relevant NYMEX futures contracts and exchange traded contracts for each derivative settlement location. Although such counterparty and third-party broker quotes are used to assess the fair value of its commodity derivative instruments, the Company does not have access to the specific assumptions used in its counterparties valuation models. Consequently,

21

additional disclosures regarding significant Level 3 unobservable inputs were not provided and the Company does not currently have sufficient corroborating market evidence to support classifying these contracts as Level 2 instruments.

As required, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values below incorporates various factors, including the impact of the counterparty’s non-performance risk with respect to the Company’s financial assets and the Company’s non-performance risk with respect to the Company’s financial liabilities. The Company has not elected to offset the fair value amounts recognized for multiple derivative instruments executed with the same counterparty, but reports them gross on its consolidated balance sheets.

Transfers between levels are recognized at the end of the reporting period. There were no transfers between levels during the 2018 and 2017 periods.

The following tables set forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2018 and December 31, 2017:

The table below presents a reconciliation of the assets and liabilities classified as Level 3 in the fair value hierarchy for the three and nine months ended September 30, 2018 and 2017.  Level 3 instruments presented in the table consist of net derivatives that, in management’s opinion, reflect the assumptions a marketplace participant would have used at September 30, 2018 and 2017.

(1) Included in gain (loss) on commodity derivatives contracts on the condensed consolidated statements of operations.

At September 30, 2018, the estimated fair value of accounts receivable and accounts and revenue payables approximates their carrying value due to their short-term nature. The estimated fair value of the Notes excluding the conversion feature at September 30, 2018 was $113.1 million calculated based on the fair value of similar non-convertible debt instruments (Level 2) since an observable quoted price of the Notes or a similar asset or liability is not readily available.  The estimated fair value of the Term Loan at

22

September 30, 2018 was $241.0 million calculated based on the fair value of similar debt instruments (Level 2) since an observable price of the Term Loan or a similar asset or liability is not readily available.  

7. Revenue from Contracts with Customers

Disaggregation of Revenue

The following represents a disaggregation of revenues and a reconciliation of total revenues as reported in the condensed consolidated statement of operations to revenue from contracts with customers:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2018		2017(1)		2018		2017(1)
	(in thousands)
Revenues
Oil and condensate	$	17,436	$	12,952	$	54,497	$	37,886
Natural gas		1,986		2,519		5,618		7,452
NGLs		2,092		2,757		7,315		7,527
Total revenues from contracts with customers	$	21,514	$	18,228	$	67,430	$	52,865

(1) Prior period amounts have not been adjusted under the modified retrospective method.

Revenue Recognition

Oil, condensate, natural gas and NGLs revenues are recognized at the point in time that control of the product is transferred to the customer and collectability is reasonably assured.  A more detailed summary of the underlying contracts that give rise to revenue and method of recognition are included below.

Oil and Condensate Sales

Under the Company’s oil and condensate sales contracts, the Company delivers all or a specified percentage of the crude oil production from specified leases to the nominated delivery point which is the outlet flange of the Company’s lease facility or at unit storage tanks.  The Company sells oil and condensate production at the delivery point and collects an agreed-upon index price, net of applicable transport differential.  The Company recognizes revenue when control transfers to the purchaser at the delivery point at the net price received.

Natural Gas and NGLs Sales

Under the Company’s gas processing contracts, the Company delivers all or a specified percentage of natural gas production to a midstream processing entity at the wellhead or the inlet of the midstream processing entity’s system.  The midstream processing entity processes the natural gas, sells the resulting NGLs and residue gas to third parties and pays the Company for the NGLs and residue gas with deductions for Post-Production Expenses.  The NGLs are subject to an incremental NGLs pricing formula based upon a percentage of NGLs extracted from the Company’s wet gas.  For the Company’s gas processing contracts, the Company evaluates whether it is the principal or the agent.  For the Company’s existing contracts, it has concluded that it is the agent and the midstream processing entity is the Company’s customer, and therefore, the Company recognizes revenue when control transfers to the midstream processing entity for the net amount of the proceeds received.  If for future contracts the Company was to conclude that it is the principal with the ultimate third party being the customer, the Company would recognize revenue for those contracts on a gross basis, with Post-Production Expenses presented gross as expenses.

Imbalances

The Company recognizes revenue for all oil, condensate, natural gas and NGLs sold to purchasers regardless of whether the sales are proportionate to the Company’s ownership interest in the property.  Production imbalances are recognized as a liability to the extent an imbalance on a specific property exceeds the Company’s share of remaining proved oil and natural gas reserves.  The Company had no material imbalances at September 30, 2018 or 2017.

Significant Judgments

Principal versus Agent

The Company engages in various types of transactions in which midstream entities process its wet gas and, in some scenarios, subsequently market resulting NGLs and residue gas to third-party customers on the Company’s behalf, such as gas processing contracts.  These types of transactions require judgment to determine whether the Company is the principal or the agent in the contract and, as a result, whether revenues are recorded gross or net.  For the Company’s existing contracts, the Company has determined that it represents the agent in the sale of products under certain gas processing and marketing agreements with midstream entities in accordance with the control model in ASC 606.  As a result, the Company presents revenue on a net basis for amounts expected to be received from third-party customers through the marketing process, with Post-Production Expenses incurred subsequent to control of the product(s) transferring to the midstream entity being netted against revenue.  

Transaction Price Allocated to Remaining Performance Obligations

A significant number of the Company’s product sales are short-term in nature with a contract term of one year or less.  For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14 that exempts it from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

For the Company’s product sales that have a contract term greater than one year, the Company has utilized the practical expedient in ASC 606-10-50-14A that states that it is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation.  Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Contract Balances

Under the Company’s customer contracts, the Company receives a remittance advice confirming purchased volumes and pricing from its customers once the Company’s performance obligations have been satisfied, at which point payment is unconditional.  Accordingly, the Company’s contracts do not give rise to contract assets or liabilities under ASC 606.  All of the Company’s revenue accounts receivable balances are attributable to revenues from contracts with customers.  

Prior-period Performance Obligations

The Company records revenue in the month its production is delivered to the purchaser.  However, settlement statements and payment may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production that was delivered to the purchaser and the price that will be received for the sale of the product including any transportation and other deductions.  The Company uses its knowledge of its properties, historical performance, contractual data, the anticipated effect of weather conditions during the month of production and prevailing market as the basis for these estimates.  The Company records the variances between its estimates and the actual amounts received in the month payment is received and such variances have historically not been material.  For the three and nine months ended September 30, 2018, revenue recognized in the reporting period related to performance obligations satisfied in prior reporting periods was not material.

8. Derivative Instruments and Hedging Activity

The Company maintains a commodity price risk management strategy that uses derivative instruments to minimize significant, unanticipated earnings fluctuations that may arise from volatility in commodity prices. The Company uses costless collars, index, basis and fixed price swaps and put and call options to hedge oil, condensate, natural gas and NGLs price risk.

All derivative contracts are carried at their fair value on the balance sheet and all changes in value are recorded in the condensed consolidated statements of operations in (loss) gain on commodity derivatives contracts.  For the three months ended September 30, 2018 and 2017, the Company reported a gain of $433,000 and a loss of $4.7 million, respectively, in the condensed consolidated statements of operations related to the change in the fair value of its commodity derivative contracts still held at September 30, 2018 and 2017.  For the nine months ended September 30, 2018 and 2017, the Company reported losses of $9.0 million and $1.9 million, respectively, in the condensed consolidated statements of operations related to the change in the fair value of its commodity derivative contracts still held at September 30, 2018 and 2017.  For the three months ended September 30, 2018 and 2017, the Company reported a loss of $3.4 million and a gain of $1.8 million, respectively, in the condensed consolidated statements of operations for the settlement of derivatives during the respective periods.  For the nine months ended September 30, 2018 and

As of September 30, 2018, all of the Company’s economic derivative hedge positions were with large institutions, which are not known to the Company to be in default on their derivative positions.  The Company is exposed to credit risk to the extent of non-performance by the counterparties in the derivative contracts discussed above; however, the Company does not anticipate non-performance by such counterparties. None of the Company’s derivative instruments contain credit-risk related contingent features.

On October 26, 2018, the Company and the Hedge Parties entered into the Hedge Party RSA to effectively terminate the Company’s current hedge positions and replace such with new secured notes to be paid in monthly installments through December 2019 (the “Hedge Party Secured Notes”).  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties described above.  The Hedge Party RSA contains certain covenants on the part of each of the Company and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements. The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.  The Hedge Party Secured Notes will be secured by an uncapped first priority security interest in the collateral that secures the Exit Facility which security interest and lien shall rank pari passu with the liens granted to the Company’s senior-most creditors (with respect to debt for borrowed money).  On November 1, 2018, the Company’s current hedge positions were terminated and the value of the Hedge Party Secured Notes was determined to be $12.4 million, subject to approval by the Bankruptcy Court.  The Hedge Party Secured Notes mature on December 31, 2019 during which time no interest shall accrue unless a default occurs under the terms thereof.  Funds in the Exit Facility will be available to make payments under the Hedge Party Secured Notes.

13. Commitments and Contingencies

Litigation

Gastar Exploration Inc. v. Christopher McArthur (Cause No.:  2015-77605) 157th Judicial District Court, Harris County, Texas.  On December 29, 2015, Gastar filed suit against Christopher McArthur (“McArthur”) in the District Court of Harris County, Texas.  The lawsuit arises from a demand letter sent by McArthur to Gastar in which he claimed to be party to an agreement with Gastar that entitled him to be paid $2.75 million for services rendered.  In August 2016, McArthur filed an amended answer admitting he had no agreement with the Company. As a result, Gastar believes McArthur’s claim has been effectively resolved. Gastar has also pursued a claim in this action against McArthur for tortious interference with an existing contract.  On October 17, 2018, the Court entered a judgment in favor of Gastar on this tortious interference claim.  Gastar is currently pursuing collection efforts.  

Torchlight Energy Resources, Inc., Torchlight Energy, Inc. v. Husky Ventures, Inc., et al., (Cause No. 429-01961-2016) 429th Judicial District Court in Collin County, Texas. Torchlight Energy Resources, Inc. and Torchlight Energy, Inc. (collectively “Torchlight”) brought a lawsuit against the Company, two of its executive officers, its chairman of the board of directors and a former director of the Company on May 3, 2016 in Collin County, Texas (the “Torchlight Lawsuit”). The Torchlight Lawsuit arose primarily out of Torchlight’s business dealings with Husky Ventures, Inc. (“Husky”) in Oklahoma. Husky and several of its employees and affiliates were also defendants in the Torchlight Lawsuit. As part of settlement negotiations between Husky and the Company in a separate lawsuit, Husky informed the Company that it had agreed to repurchase assets from Torchlight that Husky had previously sold to Torchlight (the “Torchlight Assets”). Husky offered to sell those Torchlight Assets to the Company. In the Purchase and Sale Agreement between Torchlight and Husky (the “Purchase and Sale Agreement”), Torchlight expressly acknowledged that the Torchlight Assets were to be sold to the Company and released the Company from any claims arising out of the sale of the Torchlight Assets. Despite this release, Torchlight alleged multiple causes of action against the Company and its officers and directors arising out of the sale of the Torchlight Assets and Torchlight’s other business dealings it had with Husky.

On August 17, 2016, plaintiffs nonsuited, without prejudice, their claims against the former chairman of the board.  On May 22, 2017, the court granted the Company’s motion for summary judgment and dismissed all of the plaintiffs’ claims against the Company and the Company’s other officers and directors in their entirety.  

The Company filed a counterclaim against Torchlight for breach of the release in the Purchase and Sale Agreement.  On April 26, 2018, the Court granted, in part, the Company’s motion for summary judgment on its breach-of-contract counterclaim and left for trial only the question of the Company’s damages.  On May 23, 2018, Torchlight and the Company settled the breach-of-contract counterclaim, and on May 24, 2018, the Court dismissed with prejudice all claims and counterclaims between Torchlight and the Company in the Torchlight Lawsuit.    

PennMarc Resources II, LP, et al v. Gastar Exploration USA, Inc., et al, (Civil Action No. 18-C-220 H.) Circuit Court of Marshall County, West Virginia; Venable Royalty, Ltd. et al v. Gastar Exploration USA, Inc., et al, (Civil Action No 18-C-227.) Circuit Court of Marshall County, West Virginia.  These lawsuits are related to a prior lawsuit filed by the same plaintiffs in 2017: PennMarc Resources II, LP, et al v. Gastar Exploration USA, Inc., et al, (Civil Action No17 C 214) The plaintiffs are royalty owners under various leases taken by or assigned to the Company.  The leases cover property in Marshall County, West Virginia.  The leases are among other assets that were assigned to THQ Appalachia, LLC pursuant to a purchase and sale agreement dated February 12, 2016.  In the original lawsuit, the plaintiffs alleged that the Company breached the leases by making deductions for post-production costs that were not authorized by the terms of the leases.  The plaintiffs also alleged that the unauthorized deductions were not shown on their monthly royalty statements and the failure to detail the deduction of these costs was fraudulent.  The plaintiffs asserted claims for breach of contract, breach of fiduciary duty and fraudulent concealment.  The plaintiffs sought compensatory damages and punitive damages.  The Company successfully moved to dismiss the plaintiffs’ claims in December 2017, arguing that some claims were subject to arbitration while others were premature because the plaintiffs had failed to provide written notice of a breach, as required by the leases.  The Court granted the Company’s motion to dismiss in July 2018 and dismissed the plaintiffs’ claims without prejudice.  After the motion was granted, a number of the plaintiffs complied with the leases’ pre-suit notification requirement by sending the Company formal notices of breach.  In its response to the notices, the Company asserted that it had paid royalties correctly during its ownership of the leases.  In October of 2018, PennMarc Resources II, LP refiled its lawsuit along with several of the other original plaintiffs.  Shortly thereafter, two more of the original plaintiffs, Venable Royalty, Ltd. and Venro, Ltd., filed a separate but identical lawsuit.  In both lawsuits, the plaintiffs allege the Company breached the leases by improperly deducting post-production costs.  The plaintiffs assert a claim for breach of contract and seek compensatory damages, equitable accounting, and declaratory relief.  The Company is still reviewing the lawsuits and has not yet filed an answer.     

Eagle Natrium LLC v. Gastar Exploration USA, Inc., Cause No. GD-14-7208, In the Court of Common Pleas of Allegheny County, Pennsylvania.On April 22, 2014, Eagle Natrium LLC (“Eagle”), a wholly-owned subsidiary of Axiall Corporation, filed a complaint against the Company in the Court of Common Pleas of Allegheny County, Pennsylvania seeking to enjoin Gastar’s

31

hydraulic fracturing and completion operations on three wells drilled from Gastar’s Goudy pad in Marshall County, West Virginia, or conducting any activity that poses a substantial risk of harm to Eagle’s brine operations. Gastar was the operator of approximately 16,000 acres in Marshall County, West Virginia, including a 3,300 gross acre oil and gas lease adjacent to Eagle’s facilities. Eagle asserted its right to relief based on certain of the lessor’s rights which were assigned to Eagle by the lessor solely as they relate to the brine and related facilities. A hearing on the request for preliminary injunction was held in the summer of 2014. After considering the evidence presented at the hearing and the party’s briefing, the court issued an order on October 21, 2014 denying the request for a preliminary injunction. In January 2015, Gastar began completion operations and has since completed the three wells drilled from its Goudy pad that formed the basis of Eagle’s complaint.  In 2016, the Company amended its answer and has added counterclaims seeking damages from Eagle as a result of the proceedings. Specifically, Gastar has asserted a breach of contract claim, seeking damages for lost revenues, rig up and rig down costs and attorney’s fees relating to the Pennsylvania lawsuit filed by Eagle. Eagle has also maintained its breach of contract claim against the Company.  The Court has bifurcated the proceeding into a separate liability and damages phase.  On June 25, 2018, the Court commenced a six-day bench trial on liability.  A decision on the parties’ respective liability remains pending.  

The Company has been expensing legal costs on these proceedings as they are incurred.

The Company is party to various legal proceedings arising in the normal course of business. The ultimate outcome of each of these matters cannot be absolutely determined, and the liability the Company may ultimately incur with respect to any one of these matters in the event of a negative outcome may be in excess of amounts currently accrued for with respect to such matters. Net of available insurance and performance of contractual defense and indemnity obligations, where applicable, management does not believe any such matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows.

The commencement of the Chapter 11 Cases automatically stayed certain actions against the Company, including actions to collect pre-petition indebtedness or to exercise control over the property of the Company’s bankruptcy estates, and the Company intends to seek authority to pay all general claims in the ordinary course of business notwithstanding the commencement of the Chapter 11 Cases in a manner consistent with the RSA.  The Plan filed in the Chapter 11 Cases, if confirmed as contemplated by the RSA, will provide for the treatment of claims against the Company’s bankruptcy estates, including pre-petition liabilities that have not otherwise been satisfied or addressed during the Chapter 11 Cases.

Retention Payments

On August 31, 2018, the Company, on the one hand, and each of Stephen P. Roberts, Michael A. Gerlich and Jerry R. Schuyler entered into retention bonus letters (each a “Retention Bonus Letter”) providing that each such executive will receive a cash payment (“Retention Bonus”), representing a certain percentage of his base salary, paid in a lump sum in cash on or before August 17, 2018.  In the event the executive’s employment is terminated (i) by the Company for cause (as defined in the Retention Agreement) or (ii) due to his voluntarily resignation, the executive will be required to repay to the Company 100% of the Retention Bonus (net of any taxes withheld from same) if such termination occurs before December 31, 2018 and 50% of the Retention Bonus (net of taxes withheld from same) if such termination occurs after December 31, 2018 and before July 1, 2019 (the “Repayment Obligation”). The Repayment Obligation will cease in the event that the Company fails to pay the executive’s base salary in accordance with the Company’s normal payroll practices and fails to correct any such failure within five (5) days of written notice from the executive or upon the occurrence of a change in control (as defined in the Retention Bonus Letters) of the Company. The Repayment Obligation set forth in Mr. Schuyler’s Retention Bonus Letter is reduced on a straight line basis from 100% (if termination occurs before September 1, 2018) to 0% (if termination occurs any time after June 1, 2019) for each additional month that he remains employed by the Company.

On October 25, 2018, Gastar entered into amendments (the “Retention Bonus Amendments”) to theRetention Bonus Letters.  The Retention Bonus Amendments amend each of the respective Retention Bonus Letters to specify that the definition of “Change in Control” therein does not include a change of control resulting from the acquisition of a controlling interest from the Chapter 11 Cases or an acquisition by Ares or its affiliates.  In addition, the Retention Bonus Amendments with Mr. Gerlich and Mr. Roberts provide that 100% of the retention bonus is repayable by the employee if he terminates employment without Good Reason or if the Company terminates his employment with Cause (as such terms are defined in the Retention Bonus Letters) prior to February 28, 2019, and 50% of the retention bonus is payable by the employee if such a termination occurs between February 28, 2019 and April 30, 2019.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a pure play Mid-Continent independent energy company engaged in the exploration, development and production of oil, condensate, natural gas and NGLs. Our principal business activities include the identification, acquisition, and subsequent exploration and development of oil and natural gas properties with an emphasis on unconventional reserves, such as shale resource plays.  We hold a concentrated acreage position in the normally pressured oil window of the STACK Play, an area of central Oklahoma which is home to multiple oil and natural gas-rich reservoirs including the Oswego limestone, Meramec and Osage bench formations within the Mississippi Lime, the Woodford shale and Hunton limestone formations.       

All of our current operational activities are conducted in, and our consolidated revenues are generated from, markets exclusively in the U.S.  As of September 30, 2018, our major assets consist of approximately 106,600 gross (71,200 net) acres in Oklahoma (73% developed) deemed to have multi-STACK Play potential.  

The following discussion addresses material changes in our results of operations for the three and nine months ended September 30, 2018 compared to the three and nine months ended September 30, 2017 and material changes in our financial condition since December 31, 2017. This discussion should be read in conjunction with our condensed consolidated financial statements and the notes thereto included in Part I, Item 1. “Financial Statements” of this report, as well as our 2017 Form 10-K, which includes important disclosures regarding our critical accounting policies as part of Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2017 Form 10-K.

Ability to Continue as a Going Concern

Our unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2018 contained in this report were prepared assuming that we will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of issuance of the unaudited condensed consolidated financial statements.  The significant risks and uncertainties related to our liquidity and possible acceleration of our indebtedness described herein raise substantial doubt about our ability to continue as a going concern.  See “Part II – Item 1A. Risk Factors” of this report for a discussion of certain risks that materially impact our future liquidity.

As previously reported, our ability to raise additional capital to pursue corporate objectives such as a drilling and development program at a cost of capital that enables our business to achieve a profit has been significantly adversely affected by our current capital structure.  While, historically, we have been able to reduce capital expenditures to better match available capital resources, for the reasons described below, we have reduced capital expenditures by suspending our operated drilling program but continuation of suspension of our operated drilling program could create the potential for deterioration to our core business.  In addition, as a result of the recent further significant deterioration of our equity trading values, our common and preferred stock were delisted from the NYSE American stock exchange and resumed trading on the OTCQB Venture Market (“OTCQB”).  Upon the filing by the Company of its voluntary petition for relief under the United States Bankruptcy Code (as described below), we were automatically removed from quotation on the OTCQB.  Our common and preferred stock commenced trading on the OTC Pink Operated by the OTC Markets Group Inc. (also known as the “OTC Pinks”) under the same symbols.      

To address the foregoing concerns, we and our advisors developed and evaluated alternatives for our board of directors, we engaged in a restructuring process to consider potential strategic transactions, including financing, refinancing, sale, or merger transactions, and encouraged proposals from existing stakeholders and interested third-parties.  We also elected to suspend our current operated drilling and development program in order to preserve capital for other cash needs including debt service while we considered other strategic alternatives or a possible restructuring of our debt and equity.      

Recent Developments

On July 20, 2018, Ares Management, L.P. and certain affiliated funds that hold substantially all of our indebtedness delivered the Term Sheet to us proposing that we consider a sale of the Company or other potential restructuring transaction.  The Term Sheet proposed a transaction whereby we would sell substantially all of our assets and distribute proceeds in full satisfaction of our indebtedness.  Alternatively, if such sale is not successful, the Term Sheet proposed that we engage in a restructuring of our outstanding indebtedness which may include a court-approved bankruptcy sale process that pays Ares, as holders of all of our outstanding secured indebtedness, in full or a Chapter 11 plan of reorganization that provides for an exchange of a portion of the Ares indebtedness for 100% of the equity of the Company.  

On July 23, 2018, the two directors of the Company originally nominated by Ares, Nathan W. Walton and Ronald D. Scott, resigned from the board of directors of the Company. To our knowledge at the time of the filing of this report, funds indirectly managed by Ares continue to hold all of the outstanding indebtedness of the Company under the Term Loan and the Notes.

37

Restructuring Support Agreement

On August 1, 2018, we publicly announced that we were considering strategic alternatives, including financing, refinancing, a sale or a merger transaction, and encouraged proposals from existing stakeholders and interested third-parties.  On August 21, 2018, we publicly filed a process letter that again invited proposals and informed the public how any interested party could participate and make a proposal.  The process letter established the bid deadline of October 1, 2018 (the “Bid Deadline”).  We received three bids on the Bid Deadline, none of which provided a basis for repaying Gastar’s indebtedness described below.  Our board of directors (the “Board”) determined that none of these proposals presented an actionable alternative.

In parallel with the foregoing marketing process, we engaged with funds affiliated with Ares Management LLC (“Ares”) regarding a comprehensive financial restructuring transaction.  On October 26, 2018, we entered into a restructuring support agreement (the “RSA”) with (i) AF V Energy I Holdings, L.P., an affiliate of Ares (the “Consenting Term Lender”) and party to the Third Amended and Restated Credit Agreement, dated March 3, 2017 (as amended, restated, modified, or supplemented form time to time, the “Term Loan”) (ii) certain holders affiliated with Ares (the “Consenting Noteholders”) of the Company’s Convertible Notes due 2022 issued pursuant to the indenture dated March 3, 2017 (as amended, restated, modified or supplemented from time to time, the “Indenture”), by and among Gastar, as issuer, the guarantors specified therein and Wilmington Trust, National Association, as trustee and collateral agent and (iii) certain holders affiliated with Ares (the “Ares Equity Holders” together with the Consenting Term Lender and the Consenting Noteholders, the “Consenting Parties”) of our outstanding common shares (the “Existing Common Equity”), to support a restructuring (the “Restructuring”) on the terms set forth in the term sheet annexed to the RSA (the “Restructuring Term Sheet”). The RSA contemplates that we will file for voluntary relief under chapter 11 (the “Chapter 11 Cases”) of the United States Bankruptcy Code (the “Bankruptcy Code”) in a United States Bankruptcy Court (the “Bankruptcy Court”) to implement the Restructuring pursuant to a “prepackaged” plan of reorganization (the “Plan”) and the various related transactions set forth in or contemplated by the Restructuring Term Sheet, the DIP Term Sheet (defined below) and the Exit Facility Term Sheet (defined below).  Shortly after entering into the RSA, we commenced solicitation of the Plan consistent with section 1126(b) of the Bankruptcy Code, which solicitation concluded on October 30, 2018.  

Pursuant to the terms of the RSA and the Restructuring Term Sheet, the Consenting Parties and other interest holders will receive treatment under the Plan summarized as follows:

• holders of claims under the DIP Facility (defined below) arising on account of the New Money Loans (defined below) will receive pro rata participation in the First Lien Exit Facility (defined below) in an amount equal to such claims arising on account of New Money Loans;  

• holders of claims under the DIP Facility, other than claims arising on account of the New Money Loans, will receive (a) pro rata participation in the Second Lien Exit Facility (defined below) up to an aggregate amount of $200 million and (b) to the extent any such claims exceed $200 million, such excess will receive a pro rata share of 100% of the common equity in the reorganized Company (the “New Common Equity”);

• holders of claims under the Term Loan will receive (a) to the extent there is remaining availability under the Second Lien Exit Facility, pro rata participation in the Second Lien Exit Facility in an equal face amount not to exceed $200 million and (b) to the extent any such claims remain outstanding, their pro rata share of 100% of the New Common Equity, subject to dilution upon the issuance of common stock upon exercise of the New Warrants described below and pursuant to a new management incentive plan to be entered into at the discretion of the board of the reorganized Company following emergence from bankruptcy (the “Management Incentive Plan”);

• holders of claims under the Indenture will receive their  pro rata share of 100% of the New Common Equity, subject to dilution upon the issuance of common stock upon exercise of the New Warrants described below and pursuant to the Management Incentive Plan;

• holders of claims arising out of any termination of the Company’s hedging or swap arrangements with Cargill, Inc. and NextEra Energy Marketing, LLC (collectively, the “Hedge Parties”) will receive payment in full in cash in monthly installments through December 2019 pursuant to new secured notes;

• holders of claims arising pursuant to statutory liens will receive payment in full in cash in two equal installments on the effective date of the Chapter 11 Cases and six months following such date;

• holders of claims arising from general unsecured obligations will receive payment in full in cash as set forth in the Plan;

38

• subject to certain conditions, including that such holders not seek official committee status or the appointment of a trustee or examiner, or object to or otherwise oppose the consummation of the Plan, holders of Gastar’s 8.625% Series A Cumulative Preferred Stock (“Series A Preferred Stock”) and 10.75% Series B Cumulative Preferred Stock (“Series B Preferred Stock,” and collectively with the Series A Preferred Stock, the “Existing Preferred Equity”) will receive their pro rata share based on their liquidation preference plus accumulated but unpaid dividends accrued through October 31, 2018 of warrants to purchase 2.5% of the New Common Equity; and

• subject to certain conditions, including that such holders not seek official committee status or the appointment of a trustee or examiner, or object to or otherwise oppose the consummation of the Plan, holders of the Existing Common Equity will receive their pro rata share of warrants to purchase 2.5% of the New Common Equity (together with the warrants listed in the previous bullet, the “New Warrants”).

In the event that a DIP Toggle Event (as defined in the Restructuring Term Sheet) has occurred, (i) holders of claims arising from general unsecured obligations will receive a pro rata share of the New Common Equity and (ii) all Existing Preferred Equity and Existing Common Equity and Subordinated Securities Claims will be canceled, released, and extinguished without distribution.  The occurrence of a DIP Toggle Event will not affect the other treatments contemplated by the RSA as listed above.

The RSA contains certain covenants on the part of each of the Company and the Consenting Parties, including limitations on the parties’ ability to pursue alternative transactions, commitments by the Consenting Parties to vote in favor of the Plan and commitments of the Company and the Consenting Parties to negotiate in good faith to finalize the documents and agreements governing the Plan. The RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the RSA.  The transactions described and contemplated by the Plan are all subject to the Bankruptcy Court approval at a future date.  There can be no assurance that the Bankruptcy Court will ultimately approve the transactions as described above.  

Also on October 26, 2018, we and our Hedge Parties entered into that certain Hedge Party Restructuring Support Agreement (the “Hedge Party RSA”).  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties described above.  The Hedge Party RSA contains certain covenants on the part of each of the Company and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements. The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.

We intend to complete a supplemental marketing process seeking proposal for transactions that are higher and better than the transactions contemplated by the Plan during the Chapter 11 Cases, with a bid deadline of December 17, 2018.  We intend to publicly disclose further details regarding the supplemental marketing process, including informing interested parties how they may participate and make a proposal, at a future date.  In the absence of a higher or better proposal, we intend to seek confirmation of the Plan at a hearing currently scheduled for December 20, 2018.

Voluntary Reorganization Under Chapter 11

On October 31, 2018 (the “Petition Date”), we and a subsidiary (collectively, the “Debtors”) commenced Chapter 11 proceedings and filed the Plan for reorganization under Chapter 11 of the Bankruptcy Code with the Bankruptcy Court for the Southern District of Texas. The Debtors have filed a motion with the Bankruptcy Court seeking joint administration of their Chapter 11 Cases under the caption In re: Gastar Exploration Inc., et al. We filed a motion with the Bankruptcy Court seeking joint administration of our Chapter 11 Cases.  We will continue to operate our businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.  We expect ordinary-course operations to continue substantially uninterrupted during and after the Chapter 11 Cases subject to the risks and uncertainties discussed below under Part II, Item 1A. “Risk Factors” of this report.  

Subject to certain exceptions, under the Bankruptcy Code, the voluntary filing of our petition in the Chapter 11 Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover, collect or secure a claim arising prior to the date of the filing of the Plan.  Accordingly, although the filing of the voluntary petition triggered defaults on the Debtors’ debt obligations, creditors are stayed from taking any actions against the Debtors as a result of such defaults, subject to certain limited exceptions permitted by the Bankruptcy Code.  Absent an order of the Bankruptcy Court, substantially all of the Debtors’ pre-petition liabilities are subject to settlement under the Bankruptcy Code.

For the duration of the Chapter 11 Cases, our operations and ability to develop and execute our business plan are subject to the risks and uncertainties associated with the Chapter 11 process as described in Part II, Item 1A. “Risk Factors” of this report.  As a result of these risks and uncertainties, the number of our shares of common stock and stockholders, assets, liabilities, officers and/or directors could be significantly different following the outcome of the Chapter 11 Cases, and the description of our operations,

39

properties and capital plans included in this quarterly report may not accurately reflect its operations, properties and capital plans following the Chapter 11 process.

In particular, subject to certain exceptions, under the Bankruptcy Code, the Debtors may assume, assign or reject certain executory contracts and unexpired leases subject to the approval of the Bankruptcy Court and certain other conditions.  Generally, the rejection of an executory contract or unexpired lease is treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves the Debtors of performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed breach.  Counterparties to such rejected contracts or leases may assert unsecured claims in the Bankruptcy Court against the applicable Debtors’ estate for such damages.  Generally, the assumption of an executory contract or unexpired lease requires the Debtors to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance.  Accordingly, any description of an executory contract or unexpired lease with the Debtor in this quarterly report, including where applicable a quantification of the Company’s obligations under any such executory contract or unexpired lease with the Debtor is qualified by any overriding rejection rights the Company has under the Bankruptcy Code.  Further, nothing herein is or shall be deemed an admission with respect to any claim amounts or calculations arising from the rejection of any executory contract or unexpired lease and the Debtors expressly preserve all of their rights with respect thereto.

Debtor-in-Possession Financing

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, the Company with superpriority debtor-in-possession financing (the “DIP Facility”) on the terms set forth in the term sheet attached to the RSA (the “DIP Term Sheet”). The DIP Term Sheet provides that, among other things:

• the DIP Facility shall be comprised of term loans in an aggregate amount of approximately $383.9 million, consisting of $100 million of new money loans (the “New Money Loans”) and approximately $283.9 million of refinanced term loan obligations outstanding under the Term Loan;

• upon entry of and subject to a Bankruptcy Court order granting interim approval of the DIP Facility and subject to the satisfaction or waiver of additional conditions precedent, up to $15 million of the New Money Loans (the “Interim DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount that is not less than $2.5 million for the initial draw and not less than $500,000 for each subsequent draw (or, if less, the entire amount of the unused balance of the Interim DIP Tranche);

• upon entry of and subject to a Bankruptcy Court order granting final approval (the “Final Order”) of the DIP Facility, and subject to the satisfaction or waiver of additional conditions precedent and an approved budget, up to $100 million of New Money Loans, minus any amounts of New Money Loans previously drawn by the Company prior to such date (the resulting amount, the “Final DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Final DIP Tranche);

• upon entry of and subject to the Final Order and subject to the satisfaction or waiver of additional conditions precedent, including the Company having demonstrated to the reasonable satisfaction of the DIP Lenders acting in good faith, the bona fide need for additional liquidity to preserve lease operating rights in response to actions taken or proposed to be taken by third parties, an amount equal to $100 million minus the amount of New Money Loans previously drawn by the Company prior to such date (the resulting amount, the “Reserve DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Reserve DIP Tranche); and

• subject to entry of the Final Order, approximately $283.9 million in outstanding term loan obligations consisting of principal and accrued and unpaid interest under the Term Loan as of the date of the commencement of the Chapter 11 Cases will be refinanced by loans (not constituting New Money Loans) funded under the DIP Facility.

Our entry into the DIP Facility has been approved by the Bankruptcy Court on an interim basis.  Our entry into the DIP Facility on a final basis will be considered by the Bankruptcy Court at a future date. The foregoing description of the DIP Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the DIP Facility, as approved by the Bankruptcy Court.

Exit Financing

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, the Company with an exit financing term loan facility (the “Exit Facility”) on the terms set forth in the term sheet attached to the RSA (the “Exit Facility Term Sheet”). The Exit Facility Term Sheet provides for, among other things, (a) a $100 million secured delayed draw term loan facility (the “First Lien Exit Facility”) comprised of (i) term loans consisting of New Money Loans funded under the DIP Facility and deemed funded under the First Lien Exit Facility on the effective date of the Plan and (ii) term loan commitments consisting of an amount equal to any undrawn commitment under the DIP Facility and (b) a secured term loan facility (the “Second Lien Exit Facility”) comprised of up to $200 million (as may be reduced by the Exit Lenders in their sole discretion on or prior to the effective date of the Plan), in aggregate principal amount of term loans deemed funded on the effective date of the Plan and consisting of DIP Claims and Term Loan Claims (each as defined in the RSA), as applicable (the loans under the First Lien Exit Facility and the Second Lien Exit Facility, collectively, the “Exit Loans”). The Exit Loans may not be reborrowed once repaid.

The Exit Facility is subject to customary closing conditions and approval by the Bankruptcy Court, which has not been obtained at this time. The foregoing description of the Exit Facility Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the Exit Facility, as approved by the Bankruptcy Court.

Although the Company intends to pursue the restructuring in accordance with the terms set forth in the RSA, there can be no assurance that the Company will be successful in completing a restructuring or any other similar transaction on the terms set forth in the RSA, on different terms or at all.

Oil and Natural Gas Activities

The following provides an overview of our major oil and natural gas projects. While actively pursuing specific exploration and development activities in the Mid-Continent area, there is no assurance that new drilling opportunities will be identified or that any new drilling opportunities will be successful if drilled.  We elected to suspend our current operated drilling and development program in order to preserve capital for other cash needs, including debt service and fees associated with the restructuring of our debt and equity.  We intend to maintain our capital budget to preserve our current acreage position and to continue participation in selected non-operated drilling activity.      

Mid-Continent Horizontal Oil Play.

We believe that our acreage is prospective in the normally pressured oil window of the STACK Play, an area of central Oklahoma that includes oil and natural gas-rich formations such as the Meramec, Osage and Woodford shale, ranging in depth from 6,000 to 9,000 feet, and in the shallow Oswego formation as well as the proven Hunton limestone horizontal oil play.  It is a horizontal drilling play in an area of previously drilled vertical wells with multiple productive reservoirs that are predominantly oil producing.  The STACK Play encompasses all or parts of Blaine, Canadian, Garfield, Kingfisher and Major counties in Oklahoma.  STACK is an acronym for Sooner Trend Anadarko basin Canadian and Kingfisher counties.  At September 30, 2018, we held leases covering approximately 106,600 gross (71,200 net) acres primarily in Garfield and Kingfisher Counties, Oklahoma within the STACK Play.

Our initial leasing activities in 2012 were primarily focused in northwest Kingfisher County, Oklahoma with an AMI co-participant whom we bought out and assumed operatorship of the acquired wells in December 2015.

On October 14, 2016, we executed a definitive agreement with STACK Exploration LLC (the “Investor”) to jointly develop up to 60 Gastar operated wells in the STACK Play in Kingfisher County, Oklahoma (the “Development Agreement”).  The drilling program (the “Drilling Program”) targeted the Meramec and Osage formations within the Mississippi Lime in a contract area within three townships covering approximately 32,900 gross (21,200 net) undeveloped net mineral acres under leases held by us. We serve as operator of all Drilling Program wells.

Under the Development Agreement, the Investor funded 90% of our working interest portion of drilling and completion costs to initially earn 80% of our working interest in each new well (in each case, proportionately reduced by other participating working interests in the well).  As a result, we paid 10% of our working interest portion of such costs for 20% of our original working interest in the well.  

The Drilling Program wells were to be mutually developed in three tranches of 20 wells each.  The locations of the first 20 wells, comprised of 18 Meramec formation wells and two Osage formation wells, were mutually agreed upon by us and the Investor.  Participation in the second tranche of 20 Drilling Program wells was to be at the election of the Investor and the third tranche of 20 wells was to require mutual consent.  By December 31, 2017, we had drilled and completed all 20 gross (3.2 net) wells under the first

41

tranche of the Development Agreement, all of which were on production.  As of July 31, 2017, the Investor elected not to participate in a second tranche of wells.

With respect to each 20 wells drilled under the Drilling Program, when the Investor has achieved an aggregate 15% internal rate of return for its investment for all wells, its interest will be reduced from 80% to 40% of our original working interest and our working interest increases from 20% to 60% of our original working interest.  If and when the internal rate of return of 20% for all 20 wells in the aggregate is achieved by the Investor, the Investor’s working interest decreases to 10% and our working interest increases to 90% of the working interest originally owned by us (the “final reversion”). 

If and when the final reversion of working interest in the completed 20 well tranche should occur, the Investor has the right, but not the obligation, for a period of six months after final reversion to cause us to purchase the Investor’s remaining interest in the 20 wells in the Drilling Program (the “WI Tail”) for such tranche (the “Investor Put Right”) for fair market value by applying the methodology to determine a 15% discounted present value as defined by the Development Agreement.  If the Investor fails to exercise the Investor Put Right within the six-month period after achieving final reversion, then for a period of six months thereafter, we shall have the right, but not the obligation, to purchase the WI Tail from the Investor on the same fair market value approach of the Investor Put Right.  If final reversion has not been achieved by August 19, 2024, Investor will, for a period of six months thereafter, have the right to cause us to buy Investor’s then-current interest in the Drilling Program wells at an agreed upon valuation.  Based on current commodity prices, well cost and production performance of the wells drilled in the first tranche, the 15% internal rate of return is not anticipated to be achieved.

During the three months ended September 30, 2018, we spud three gross (2.3 net) operated Osage wells and commenced flow back on three gross (2.3 net) operated Osage wells.  During the nine months ended September 30, 2018, we spud 10 gross (8.9 net) operated Osage wells and commenced flow back on 11 gross (9.9 net) operated Osage wells.  During the three and nine months ended September 30, 2018, we spud two gross (2.0 net) operated Meramec wells.  

To date in 2018, we have elected to participate in various non-operated wells in the Meramec, Osage and Oswego formations to further delineate our STACK Play acreage position.  Of the 2018 non-operated wells that we have elected to participate, currently five gross (0.6 net) non-operated Meramec wells, seven gross (2.1 net) non-operated Osage wells and six gross (0.3 net) non-operated Oswego wells have been placed on production.  We anticipate that we will continue to receive election notices regarding proposed non-operated STACK wells.

Total oil, condensate, natural gas and NGLs revenues (exclusive of the effects of hedging) as reported were $21.5 million for the three months ended September 30, 2018, up 18% from $18.2 million for the three months ended September 30, 2017.  Pursuant to current accounting guidance, total oil, condensate, natural gas and NGLs revenues for the three months ended September 30, 2018 were net of $1.3 million of treating, transportation and gathering costs which historically have been reported separately as an expense.  The increase in revenues was the result of a 23% increase in weighted average realized equivalent prices partially offset by a 4% decrease in production.  Average daily production on an equivalent basis was 6.0 MBoe/d for the three months ended September 30, 2018 compared to 6.2 MBoe/d for the same period in 2017.  Average daily production on an equivalent basis for the three months ended September 30, 2017 included 2.8 MBoe/d of WEHLU production.  The WEHLU sale closed on February 28, 2018.  STACK only average daily equivalent production on an equivalent basis was 6.0 MBoe/d for the three months ended September 30, 2018 compared to 3.4 MBoe/d for the same period in 2017.  STACK only oil, condensate and NGLs production represented approximately 66% of STACK only production for the three months ended September 30, 2018 compared to 68% of STACK only production for the three months ended September 30, 2017.      

Oil and condensate revenues as reported represented approximately 81% and 71% of our total oil, condensate, natural gas and NGLs revenues for the three months ended September 30, 2018 and 2017, respectively.  Total liquids revenues (oil, condensate and NGLs) as reported represented approximately 91% of our total oil, condensate, natural gas and NGLs revenues for the three months ended September 30, 2018 and 86% of our total oil, condensate, natural gas and NGLs revenues for the three months ended September 30, 2017.  

During the three months ended September 30, 2018, we had commodity derivative contracts covering approximately 89% of our oil and condensate production.  The impact of hedging on oil and condensate sales during the three months ended September 30, 2018 was a decrease of $3.0 million in oil and condensate revenues and resulted in a decrease in total price realized from $68.86 per Bbl to $57.20 per Bbl.  The loss on oil and condensate commodity derivatives contracts settled during the period included $408,000 for the amortization of prepaid premiums.  During the three months ended September 30, 2017, the impact of hedging on oil and condensate sales was an increase of $1.4 million, which resulted in an increase in total price realized from $46.56 per Bbl to $51.77 per Bbl.  On a total liquids basis, we were approximately 73% hedged for the three months ended September 30, 2018.  We allocated 15% of our crude hedges as price protection for our NGLs production for the quarters ended September 30, 2018 and 2017.  We have not designated any of these derivatives contracts as hedges as prescribed by accounting rules.  

During the three months ended September 30, 2018, we had commodity derivative contracts covering approximately 40% of our natural gas production.  The impact of hedging on natural gas sales during the three months ended September 30, 2018 was an increase of $115,000 in natural gas revenues and resulted in an increase in total price realized from $1.76 per Mcf to $1.86 per Mcf, after reflecting Post-Production Expenses of $0.68 per Mcf.  The gain on natural gas commodity derivatives contracts settled during the period was reduced by $68,000 for deferred put premiums.  During the three months ended September 30, 2017, the impact of hedging on natural gas sales was an increase of $72,000, which resulted in an increase in total price realized from $2.62 per Mcf to $2.69 per Mcf.  We have not designated any of these derivatives contracts as hedges as prescribed by accounting rules.  

During the three months ended September 30, 2018, we had commodity derivative contracts covering approximately 37% of our NGLs production. The impact of hedging on NGLs sales during the three months ended September 30, 2018 was a decrease of $521,000 in NGLs revenues and resulted in a decrease in total price realized from $19.26 per Bbl to $14.46 per Bbl, after reflecting Post-Production Expenses of $4.61 per Bbl.  The loss on NGLs commodity derivatives contracts settled during the period included $72,000 for amortization of prepaid premiums.  During the three months ended September 30, 2017, the impact of hedging on NGLs sales was an increase of $256,000 in NGLs revenues which resulted in an increase in total price realized from $20.64 per Bbl to $22.55 per Bbl.  We have not designated any of these derivatives contracts as hedges as prescribed by accounting rules.  

The change in mark to market value for outstanding commodity derivatives contracts for the three months ended September 30, 2018 was a gain of $433,000 compared to a loss of $4.7 million for the three months ended September 30, 2017. The change in the

47

mark to market value is primarily the result of changes in hedge contracts and volumes hedged and the future price curve compared to the prior year.

For additional information regarding our oil and condensate hedging positions as of September 30, 2018, see Part I, Item 1. “Financial Statements, Note 8 – Derivative Instruments and Hedging Activity” of this report.

On October 26, 2018, in conjunction with entry into the RSA, we and the Hedge Parties entered into the Hedge Party RSA to effectively terminate our current hedge positions and replace such with new secured notes to be paid in monthly installments through December 2019 (the “Hedge Party Secured Notes”).  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties.  The Hedge Party RSA contains certain covenants on the part of each of us and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements.  The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.  On November 1, 2018, the Company’s current hedge positions were terminated and the value of the Hedge Party Secured Notes was determined to be $12.4 million, subject to approval by the Bankruptcy Court.

Production taxes. We reported production taxes of $1.1 million for the three months ended September 30, 2018 compared to $721,000 for the three months ended September 30, 2017.  The increase in production taxes primarily resulted from an $817,000 increase in STACK Play production taxes due to new Mid-Continent STACK Play wells, higher oil and condensate prices and higher tax rates due to Oklahoma state tax law changes on exempt horizontal wells offset by a $406,000 decrease in production taxes resulting from the WEHLU sale.  Production taxes for the three months ended September 30, 2018 and 2017 were approximately 5.3% and 4.0%, respectively, of oil, condensate, natural gas and NGLs revenues.  Effective July 1, 2018, Oklahoma state tax law for exempt horizontal wells that were taxed at 2% changed to increase the rate to 5%.  

Lease operating expenses. We reported LOE of $5.5 million for the three months ended September 30, 2018 compared to $6.2 million for the three months ended September 30, 2017.  The decrease in LOE is due to a $3.1 million decrease in total LOE as a result of the WEHLU sale offset by a $2.4 million increase in total STACK Play LOE due to new wells and higher water disposal costs.  Our total LOE was $9.94 per Boe for the three months ended September 30, 2018 compared to $10.80 per Boe for the same period in 2017.  

Transportation, treating and gathering. Pursuant to current accounting guidance, treating, transportation and gathering expense of $1.3 million was recorded as a reduction to oil, condensate, natural gas and NGLs revenues for the three months ended September 30, 2018.  We reported treating, transportation and gathering expense of $436,000 for the three months ended September 30, 2017.  The increase in these costs is due primarily to new wells and changes in Oklahoma marketing contracts from primarily percent of proceeds contracts to a combination of fixed charges basis and percent of proceeds contracts.    

Depreciation, depletion and amortization. We reported depreciation, depletion and amortization (“DD&A”) expense of $7.5 million for the three months ended September 30, 2018 up from $6.1 million for the three months ended September 30, 2017. The increase in DD&A expense was the result of a 28% increase in the DD&A rate due to the sale of WEHLU and the removal of PUD locations as of June 30, 2018 due to uncertainty regarding the financing required for development of PUD reserves partially offset by a 4% decrease in production.  The DD&A rate for the three months ended September 30, 2018 was $13.55 per Boe compared to $10.59 per Boe for the same period in 2017.

General and administrative expense. We reported general and administrative expenses of $11.6 million for the three months ended September 30, 2018 compared to $4.1 million for the three months ended September 30, 2017.  Non-cash stock-based compensation expense, which is included in general and administrative expense, was $543,000 and $1.8 million for the three months ended September 30, 2018 and 2017, respectively.  Excluding stock-based compensation expense, general and administrative expense increased $8.7 million to $11.0 million for the three months ended September 30, 2018 compared to the three months ended September 30, 2017.  This increase is primarily due to higher professional fees of approximately $5.4 million for the strategic review process, $1.9 million of retention bonus expense and increased legal fees of $862,000.  We expect that our general and administrative expenses will continue to increase throughout the remainder of 2018 due to additional expenses incurred in connection with our Chapter 11 filings.  

Interest expense.  We reported interest expense of $10.5 million for the three months ended September 30, 2018 compared to $10.2 million for the three months ended September 30, 2017.  The increase in interest expense is due primarily to increased Term Loan interest of $688,000 resulting from a higher interest rate and principal balance due to paid-in-kind interest coupled with an additional $221,000 of amortization of deferred financing costs and debt discount offset by a $630,000 increase in capitalized interest.  

48

Dividends on preferred stock. Accumulated undeclared and unpaid dividends on preferred stock totaled$3.6 million for the three months ended September 30, 2018 comprised of $2.2 million for the Series A Preferred Stock and $1.4 million for the Series B Preferred Stock.  Dividends on preferred stock totaled $1.2 million and accumulated undeclared and unpaid dividends on preferred stock totaled $2.4 million for the three months ended September 30, 2017.  On April 9, 2018, we declared a special cash dividend on the Series A Preferred Stock and Series B Preferred Stock to pay in full all accumulated and unpaid cash dividends accrued since August 1, 2017 at an annualized 8.625% and 10.75%, respectively, through the payment date.  The April 2018 Series A Preferred Stock dividend of $6.5 million and the Series B Preferred Stock dividend of $4.3 million were paid on April 30, 2018 to holders of record at the close of business on April 20, 2018, which paid all unpaid dividends that accumulated in respect to the Series A Preferred Stock and Series B Preferred Stock at such time.  We continued to declare and pay dividends on the Series A Preferred Stock and Series B Preferred Stock through June 30, 2018.  On June 11, 2018, we elected to suspend the declaration and payment of monthly cash dividends on the Series A Preferred Stock and Series B Preferred Stock commencing July 2018 to maintain liquidity and support our capital investment program.  On June 29, 2018, we entered into Amendment No. 4 to the Term Loan and the Second Supplemental Indenture, both of which prohibit us from making cash dividends or distributions on or with respect to our capital stock, other than cash dividends on our Series A Preferred Stock and our Series B Preferred Stock declared for the month of June 2018, which were paid on July 2, 2018.    

Nine Months Ended September 30, 2018 compared to the Nine Months Ended September 30, 2017

Revenues. Total oil, condensate, natural gas and NGLs revenues (exclusive of the effects of hedging) as reported were $67.4 million for the nine months ended September 30, 2018, up 28% from $52.9 million for the nine months ended September 30, 2017.  Pursuant to current accounting guidance, total oil, condensate, natural gas and NGLs revenues for the nine months ended September 30, 2018 were net of $3.4 million of treating, transportation and gathering costs which historically have been reported separately as an expense.  The increase in revenues was the result of a 21% increase in weighted average realized equivalent prices coupled with a 6% increase in production.  Average daily production on an equivalent basis was 6.3 MBoe/d for the nine months ended September 30, 2018 compared to 6.0 MBoe/d for the same period in 2017.  Average daily production on an equivalent basis for the nine months ended September 30, 2018 and 2017 included 0.6 MBoe/d and 3.1 MBoe/d, respectively, of WEHLU production.  The WEHLU sale closed on February 28, 2018.  STACK only average daily equivalent production on an equivalent basis was 5.7 MBoe/d for the nine months ended September 30, 2018 compared to 2.9 MBoe/d for the same period in 2017.  STACK only oil, condensate and NGLs production represented approximately 68% of STACK only production for both the nine months ended September 30, 2018  and 2017.      

Oil and condensate revenues as reported represented approximately 81% and 72% of our total oil, condensate, natural gas and NGLs revenues for the nine months ended September 30, 2018 and 2017, respectively.  Total liquids revenues (oil, condensate and NGLs) as reported represented approximately 92% of our total oil, condensate, natural gas and NGLs revenues for the nine months ended September 30, 2018 and 86% of our total oil, condensate, natural gas and NGLs revenues for the nine months ended September 30, 2017.  

During the nine months ended September 30, 2018, we had commodity derivative contracts covering approximately 91% of our oil and condensate production.  The impact of hedging on oil and condensate sales during the nine months ended September 30, 2018 was a decrease of $7.7 million in oil and condensate revenues and resulted in a decrease in total price realized from $65.14 per Bbl to $55.88 per Bbl.  The loss on oil and condensate commodity derivatives contracts settled during the period included $1.4 million for the amortization of prepaid premiums.  During the nine months ended September 30, 2017, the impact of hedging on oil and condensate sales was an increase of $4.6 million, which resulted in an increase in total price realized from $47.03 per Bbl to $52.78 per Bbl.  On a total liquids basis, we were approximately 75% hedged for the nine months ended September 30, 2018.  We allocated 15% of our crude hedges as price protection for our NGLs production for the nine months ended September 30, 2018 and 2017.  We have not designated any of these derivatives contracts as hedges as prescribed by accounting rules.  

During the nine months ended September 30, 2018, we had commodity derivative contracts covering approximately 51% of our natural gas production.  The impact of hedging on natural gas sales during the nine months ended September 30, 2018 was an increase of $423,000 in natural gas revenues and resulted in an increase in total price realized from $1.72 per Mcf to $1.85 per Mcf, after reflecting Post-Production Expenses of $0.64 per Mcf.  The gain on natural gas commodity derivatives contracts settled during the period was reduced by $135,000 for deferred put premiums.  During the nine months ended September 30, 2017, the impact of hedging on natural gas sales was an increase of $235,000, which resulted in an increase in total price realized from $2.71 per Mcf to $2.80 per Mcf.  We have not designated any of these derivatives contracts as hedges as prescribed by accounting rules.  

During the nine months ended September 30, 2018, we had commodity derivative contracts covering approximately 38% of our NGLs production.  The impact of hedging on NGLs sales during the nine months ended September 30, 2018 was a decrease of $1.4 million in NGLs revenues and resulted in a decrease in total price realized from $20.79 per Bbl to $16.91 per Bbl, after reflecting Post-Production Expenses of $3.74 per Bbl.  The loss on NGLs commodity derivatives contracts settled during the period included $243,000 for amortization of prepaid premiums.  During the nine months ended September 30, 2017, the impact of hedging

49

on NGLs sales was an increase of $817,000 in NGLs revenues which resulted in an increase in total price realized from $19.87 per Bbl to $22.02 per Bbl.  We have not designated any of these derivatives contracts as hedges as prescribed by accounting rules.  

The change in mark to market value for outstanding commodity derivatives contracts for the nine months ended September 30, 2018 was a loss of $9.0 million compared to a loss of $1.9 million for the nine months ended September 30, 2017. The change in the mark to market value is primarily the result of changes in hedge contracts and volumes hedged and the future price curve compared to the prior year.

For additional information regarding our oil and condensate hedging positions as of September 30, 2018, see Part I, Item 1. “Financial Statements, Note 8 – Derivative Instruments and Hedging Activity” of this report.

On October 26, 2018, in conjunction with entry into the RSA, we and the Hedge Parties entered into the Hedge Party RSA to effectively terminate our current hedge positions and replace such with the Hedge Party Secured Notes.  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties.  The Hedge Party RSA contains certain covenants on the part of each of us and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements.  The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.

Production taxes. We reported production taxes of $2.7 million for the nine months ended September 30, 2018 compared to $1.7 million for the nine months ended September 30, 2017.  The increase in production taxes is primarily due to a $1.6 million increase in STACK Play production taxes resulting from new Mid-Continent STACK Play wells and higher tax rates due to Oklahoma state tax law changes on exempt horizontal wells offset by a $565,000 decrease in production taxes resulting from the WEHLU sale.  Production taxes for the nine months ended September 30, 2018 and 2017 were approximately 4.1% and 3.2%, respectively, of oil, condensate, natural gas and NGLs revenues.  Effective July 1, 2018, Oklahoma state tax law for exempt horizontal wells that were taxed at 2% changed to increase the rate to 5%.

Lease operating expenses. We reported LOE of $17.7 million for the nine months ended September 30, 2018 compared to $16.4 million for the nine months ended September 30, 2017.  The increase in LOE is primarily due to a $7.6 million increase in recurring STACK Play LOE due to new wells with higher water disposal costs coupled with a $215,000 increase in workover costs offset by a $6.5 million decrease in LOE costs eliminated with the sale of WEHLU.  Our total LOE was $10.24 per Boe for the nine months ended September 30, 2018 compared to $9.98 per Boe for the same period in 2017.  

Transportation, treating and gathering. Pursuant to current accounting guidance, treating, transportation and gathering expense of $3.4 million was recorded as a reduction to oil, condensate, natural gas and NGLs revenues for the nine months ended September 30, 2018.  We reported treating, transportation and gathering expense of $1.2 million for the nine months ended September 30, 2017.  The increase in these costs is due primarily to new wells and changes in Oklahoma marketing contracts from primarily percent of proceeds contracts to a combination of fixed charges basis and percent of proceeds contracts.    

Depreciation, depletion and amortization. We reported DD&A expense of $24.0 million for the nine months ended September 30, 2018 up from $16.8 million for the nine months ended September 30, 2017.  The increase in DD&A expense was the result of a 36% increase in the DD&A rate due to the sale of WEHLU during the first quarter of 2018 and the removal of PUD locations as of June 30, 2018 due to uncertainty regarding the financing required to develop PUD reserves coupled with an 6% increase in production.  The DD&A rate for the nine months ended September 30, 2018 was $13.86 per Boe compared to $10.21 per Boe for the same period in 2017.

Impairment of oil and natural gas properties.  We reported an impairment of oil and natural gas properties of $18.0 million for the nine months ended September 30, 2018.  The impairment was the result of the reclassification of PUD reserves to unproven reserves.  Our PUD reserves, other than the PUD reserves associated with certain wells developed prior to June 30, 2018 or in the process of drilling and completion at June 30, 2018, were reclassified as unproved due to our inability to meet the reasonable certainty criteria for proved reserves, as prescribed under the SEC rules primarily due to the uncertainties regarding the availability and timing of funds required to develop these reserves.  Had we continued to reflect the PUD reserves at June 30, 2018, we would not have recorded an impairment.  A significant amount of our PUD reserves that were reclassified to unproved remain economically producible at current commodities prices, and we may report PUD reserves in future filings if we can determine that we have the financial capability to execute a development plan.

General and administrative expense. We reported general and administrative expenses of $25.4 million for the nine months ended September 30, 2018 compared to $12.5 million for the nine months ended September 30, 2017.  Non-cash stock-based compensation expense, which is included in general and administrative expense, was $3.4 million and $4.0 million for the nine

50

months ended September 30, 2018 and 2017, respectively.  Excluding stock-based compensation expense, general and administrative expense increased $13.5 million to $22.0 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017.  This increase is primarily due to higher professional fees of approximately $6.6 million for the strategic review process, $3.5 of severance costs, $1.8 million of additional bonus expense, increased legal fees of $1.1 million and higher rent expense of $444,000.  We expect that our general and administrative expenses will continue to increase throughout the remainder of 2018 due to additional expenses incurred in connection with our Chapter 11 filings.

Interest expense.  We reported interest expense of $30.6 million for the nine months ended September 30, 2018 compared to $29.7 million for the nine months ended September 30, 2017.  The increase in interest expense is due primarily to increased Term Loan interest resulting from a higher principal balance due to paid-in-kind interest.  

Loss on early extinguishment of debt.  We reported a loss on early extinguishment of debt of $12.2 million for the nine months ended September 30, 2017 comprised of a $7.0 million penalty for the early satisfaction and discharge of our Former Notes and the $5.2 million write-off of the remaining deferred financing costs related to the Former Notes and our Revolving Credit Facility.

Dividends on preferred stock. Dividends on preferred stock totaled $7.2 million for the nine months ended September 30, 2018 comprised of $4.4 million for the Series A Preferred Stock and $2.8 million for the Series B Preferred Stock.  Undeclared cumulative dividends on preferred stock totaled $3.6 million for the nine months ended September 30, 2017 comprised of $2.2 million for the Series A Preferred Stock and $1.4 million for the Series B Preferred Stock.  Dividends on preferred stock totaled $8.4 million and undeclared cumulative dividends on preferred stock totaled $2.4 million for the nine months ended September 30, 2017.  On April 9, 2018, we declared a special cash dividend on the Series A Preferred Stock and Series B Preferred Stock to pay in full all accumulated and unpaid cash dividends accrued since August 1, 2017 at an annualized 8.625% and 10.75%, respectively, through the payment date.  The April 2018 Series A Preferred Stock dividend of $6.5 million and the Series B Preferred Stock dividend of $4.3 million were paid on April 30, 2018 to holders of record at the close of business on April 20, 2018, which paid all unpaid dividends that accumulated in respect to the Series A Preferred Stock and Series B Preferred Stock at such time.  We continued to declare and pay dividends on the Series A Preferred Stock and Series B Preferred Stock through June 30, 2018.  On June 11, 2018, we elected to suspend the declaration and payment of monthly cash dividends on the Series A Preferred Stock and Series B Preferred Stock commencing July 2018 to maintain liquidity and support our capital investment program.  On June 29, 2018, we entered into Amendment No. 4 to the Term Loan and the Second Supplemental Indenture, both of which prohibit us from making cash dividends or distributions on or with respect to our capital stock, other than cash dividends on our Series A Preferred Stock and our Series B Preferred Stock declared for the month of June 2018, which were paid on July 2, 2018.

Liquidity and Capital Resources

Overview. Our decisions regarding capital structure, hedging and drilling have historically been based upon many factors, including anticipated future commodity pricing, expected economic conditions and recoverable reserves.  Historically, our primary sources of liquidity and capital resources were existing cash balances, internally generated cash flows from operating activities, asset sales and possible capital markets transactions, to the extent available on acceptable terms.  Our cash flows from operations have been impacted by various factors, the most significant of which is the market pricing for oil, condensate, natural gas and NGLs. The pricing for these commodities is volatile, and the factors that impact such market pricing are global and therefore outside of our control. Volatility in commodity prices also impacts estimated quantities of proved reserves. Our longer term operating cash flows are dependent upon reserve replacement and the level of costs required for ongoing operations. We are required to make investments to fund activity necessary to offset the inherent declines in production and proved crude oil and natural gas reserves. Our ability to maintain and grow reserves and production is highly dependent on the success of our drilling program and our ability to add reserves economically.

We suspended our current operated drilling and development program in August 2018 in order to preserve capital for other cash needs including debt service while we considered other strategic alternatives or a possible restructuring of our debt and equity.  In addition, we expect our general and administrative expenses will continue to increase throughout the remainder of 2018 due to anticipated additional expenses incurred in connection with our bankruptcy filings.  As a result, our long-term liquidity requirements, the adequacy of our capital resources and our ability to continue as a going concern are difficult to predict at this time and ultimately cannot be determined until the Plan has been confirmed, if at all, by the Bankruptcy Court.   See “Part II – Item 1A Risk Factors” for a discussion of certain risks that materially impact our future liquidity.

Debtor-in-Possession Financing

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, us with the DIP Facility on the terms set forth in the DIP Term Sheet. The DIP Term Sheet provides that, among other things:

51

• the DIP Facility shall be comprised of term loans in an aggregate amount of approximately $383.9 million, consisting of $100 million of the New Money Loans and approximately $283.9 million of refinanced term loan obligations outstanding under the Term Loan;

• upon entry of and subject to a Bankruptcy Court order granting interim approval of the DIP Facility and subject to the satisfaction or waiver of additional conditions precedent, up to $15 million of the New Money Loans may be drawn by us upon three business days’ notice in one or more draws in an amount that is not less than $2.5 million for the initial draw and not less than $500,000 for each subsequent draw (or, if less, the entire amount of the unused balance of the Interim DIP Tranche);

• upon entry of and subject to a Bankruptcy Court order granting the Final Order of the DIP Facility, and subject to the satisfaction or waiver of additional conditions precedent and an approved budget, up to $100 million of New Money Loans, minus any amounts of New Money Loans previously drawn by the Company prior to such date may be drawn by us upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Final DIP Tranche);

• upon entry of and subject to the Final Order and subject to the satisfaction or waiver of additional conditions precedent, including us having demonstrated to the reasonable satisfaction of the DIP Lenders acting in good faith, the bona fide need for additional liquidity to preserve lease operating rights in response to actions taken or proposed to be taken by third parties, an amount equal to $100 million minus the amount of New Money Loans previously drawn by the Company prior to such date may be drawn by us upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Reserve DIP Tranche); and

• subject to entry of the Final Order, approximately $283.9 million in outstanding term loan obligations consisting of principal and accrued and unpaid interest under the Term Loan as of the date of the commencement of the Chapter 11 Cases will be refinanced by loans (not constituting New Money Loans) funded under the DIP Facility.

Our entry into the DIP Facility has been approved by the Bankruptcy Court on an interim basis.  Our entry into the DIP Facility on a final basis will be considered by the Bankruptcy Court at a future date.  The foregoing description of the DIP Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the DIP Facility, as approved by the Bankruptcy Court.

Exit Financing

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, the Company with the Exit Facility on the terms set forth in the Exit Facility Term Sheet. The Exit Facility Term Sheet provides for, among other things, (a) a $100 million First Lien Exit Facility comprised of (i) term loans consisting of New Money Loans funded under the DIP Facility and deemed funded under the First Lien Exit Facility on the effective date of the Plan and (ii) term loan commitments consisting of an amount equal to any undrawn commitment under the DIP Facility and (b) the Second Lien Exit Facility comprised of up to $200 million (as may be reduced by the Exit Lenders in their sole discretion on or prior to the effective date of the Plan), in aggregate principal amount of term loans deemed funded on the effective date of the Plan and consisting of DIP Claims and Term Loan Claims (each as defined in the RSA), as applicable. The Exit Loans may not be reborrowed once repaid.

The Exit Facility is subject to customary closing conditions and approval by the Bankruptcy Court, which has not been obtained at this time. The foregoing description of the Exit Facility Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the Exit Facility, as approved by the Bankruptcy Court.

On October 26, 2018, we and our Hedge Parties entered into the Hedge Party RSA to effectively terminate our current hedge positions and replace such with the Hedge Party Secured Notes.  The Hedge Party Secured Notes will be secured by an uncapped first priority security interest in the collateral that secures the Exit Facility which security interest and lien shall rank pari passu with the liens granted to our senior-most creditors (with respect to debt for borrowed money).  The Hedge Party Secured Notes mature on December 31, 2019 during which time no interest shall accrue unless a default occurs under the terms thereof.  Funds in the Exit Facility will be available to make payments under the Hedge Party Secured Notes.  

Although the Company intends to pursue the restructuring in accordance with the terms set forth in the RSA, there can be no assurance that the Company will be successful in completing a restructuring or any other similar transaction on the terms set forth in the RSA, on different terms or at all.

For the nine months ended September 30, 2018, we reported cash flows provided by operating activities of $37.5 million.  For the nine months ended September 30, 2018, we reported net cash used in investing activities of $18.5 million primarily resulting from $112.8 million for the development of oil and natural gas properties offset by the inclusion of proceeds from the sale oil and natural gas properties of $96.3 million.  For the nine months ended September 30, 2018, we reported net cash used in financing activities of $15.0 million primarily due to $13.3 million in dividends declared and paid and $1.3 million for tax withholding related to restricted stock award vestings.  As a result of these activities, our cash and cash equivalents and restricted cash balance increased by $4.0 million, resulting in a cash and cash equivalents and restricted cash balance of $17.6 million at September 30, 2018.

At September 30, 2018, we had a net working capital deficit of approximately $28.4 million.  As of November 9, 2018, our cash balance was $11.6 million, including $11.4 of DIP Facility funds, and we had $283.9 million of Term Loan borrowings and $162.5 million of Notes outstanding.

Future capital and other expenditure requirements.  Capital expenditures for the remainder of 2018 are difficult to predict at this time and ultimately cannot be determined until the Plan has been confirmed, if at all, by the Bankruptcy Court..     

Operating cash flow and commodity hedging activities. Our operating cash flow is sensitive to many variables, the most significant of which is the volatility of prices for oil, condensate, natural gas and NGLs. Prices for these commodities are determined primarily by prevailing market conditions including national and worldwide economic activity, weather, infrastructure capacity to reach markets, supply levels and other variable factors. These factors are beyond our control and are difficult to predict.

At September 30, 2018, the estimated fair value of all of our commodity derivative instruments was a net liability of $15.8 million, comprised of current and non-current liabilities. By removing the price volatility from a portion of our oil, condensate, natural gas and NGLs sales, we have mitigated, but not eliminated, the potential effects of changing prices on our operating cash flows for those periods.

As of September 30, 2018, all of our commodity derivative hedge positions were with large institutions, each of which is not known to us to be in default on their derivative positions. We are exposed to credit risk to the extent of non-performance by the counterparties in the derivative contracts discussed above; however, we do not anticipate non-performance by such counterparties.

On October 26, 2018, in conjunction with entry into the RSA, we and the Hedge Parties entered into the Hedge Party RSA to effectively terminate our current hedge positions and replace such with the Hedge Party Secured Notes.  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties.  The Hedge Party RSA contains certain covenants on the part of each of us and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements.  The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.  The Hedge Party Secured Notes will be secured by an uncapped first priority security interest in the collateral that secures the Exit Facility which security interest and lien shall rank pari passu with the liens granted to our senior-most creditors (with respect to debt for borrowed money).  The Hedge Party Secured Notes mature on December 31, 2019 during which time no interest shall accrue unless a default occurs under the terms thereof.  Funds in the Exit Facility will be available to make payments under the Hedge Party Secured Notes.  On November 1, 2018, our current hedge positions were terminated and the value of the Hedge Party Secured Notes was determined to be $12.4 million, subject to approval by the Bankruptcy Court.  

Term Loan Facility.  On March 3, 2017, the Company entered into a $250.0 million Term Loan pursuant to the Third Amended and Restated Credit Agreement among the Company, as borrower, the guarantors party thereto, funds managed indirectly by Ares Management LLC, as lenders, and Wilmington Trust, National Association, as Administrative Agent (the “Term Loan”). The Term Loan was issued at par and bears interest at a per annum rate equal to 8.5%, payable on a quarterly basis on each March 31, June 30, September 30 and December 31 of each year, commencing March 31, 2017, and has a scheduled maturity of March 3, 2022.  In addition, the Term Loan is subject to an interest “make-whole” and repayment premium, such that any repayment or prepayment of the loans thereunder prior to the stated maturity date shall be subject to the payment of a repayment premium, and depending on the date of such repayment or prepayment, the applicable interest “make-whole” amount, with the amount of such repayment premium decreasing over the life of the Term Loan.

On March 20, 2017, we, together with the parties thereto, entered into an Amendment No. 1 to the Term Loan credit agreement which amendment permitted the issuance of the Additional Notes.  

On August 2, 2017, we entered into Amendment No. 2 to the Term Loan credit agreement allowing us to elect to PIK interest on the Term Loan, upon proper notice, 100% of interest payments due after June 30, 2017 and prior to December 1, 2018 and at our election, PIK between 0% and 50% of any interest payments occurring after December 31, 2018 (other than interest due on the maturity date or the date of any repayment or prepayment).  The Term Loan interest rate increased to 10.25% for all interest periods

53

post June 30, 2017 and the PIK interest shall be payable by capitalizing and adding such amounts to the outstanding principal amount of the Term Loan on the applicable interest payment date.

On September 18, 2017, we, together with the parties thereto, entered into Amendment No. 3 to the Term Loan credit agreement, which among other things, expressly provided that certain assignments of oil and gas properties made or to be made by the Company to Red Bluff, pursuant to the Red Bluff PSA, are permitted by the Term Loan and are not subject to the mandatory prepayment provisions applicable to “Asset Sales” under the Term Loan.

On June 29, 2018, we entered into Amendment No. 4 to the Term Loan credit agreement, which among other things, (i) reduced the period we could cure a default resulting from the failure to comply with certain covenants applicable to the Term Loan from 30 days to 15 days, (ii) waived certain defaults under the Term Loan and (iii) prohibited us from making cash dividends or distributions on or with respect to our capital stock, other than cash dividends on our Series A Preferred Stock and Series B Preferred Stock declared for the month of June 2018 and paid on July 2, 2018.

The Term Loan is secured by a first-priority lien on substantially all of the assets of the Company and its sole subsidiary, excluding certain assets as customary exceptions.  

The Term Loan contains various customary covenants for credit facilities of this type, including, among others, restrictions on granting liens, incurrence of other indebtedness, payments of certain dividends and other restricted payments, engaging in transactions with affiliates, dispositions of assets and other, in each case subject to certain baskets and exceptions.

All outstanding amounts owed become due and payable upon the occurrence of certain usual and customary events of default, including among others:

• Failure to make payments;

• Non-performance of covenants and obligations continuing beyond any applicable grace period; and

• The occurrence of a change in control of the Company, as defined in the Term Loan.

Pursuant to Amendment No. 2 to the Term Loan credit agreement, we elected to pay in kind 100% of the interest due for the period June 30, 2017 to July 1, 2018 in the amount of $26.8 million, thus increasing the outstanding principal balance of the Term Loan to $276.8 million.  We also elected to pay in kind 100% of the interest due for the period July 2, 2018 to September 30, 2018 in the amount of $7.0 million and such was accrued at September 30, 2018.  Had the interest payment date not fallen on a weekend outside of quarter end, the outstanding principal balance of the Term Loan would have been $283.8 million at September 30, 2018.

Our voluntary filing of our petition in the Chapter 11 Cases constituted an event of default that accelerated our obligations pursuant to the Term Loan.  Under the Bankruptcy Code, the creditors under the Term Loan and other debt agreements are stayed from taking any action against the Company as a result of an event of default.  See “Overview – Recent Developments” above for additional details about the Chapter 11 Cases and the proposed Plan.

Notes. On March 3, 2017 and March 21, 2017, we issued for cash at par $125.0 million and $75.0 million, respectively, principal amounts of Convertible Notes due 2022 (the “Notes”) under the Indenture. The Notes bear interest initially at 6.0% per annum.  On May 5, 2017, $37.5 million principal amount of the Notes were exchanged for 25,456,521 newly issued shares of our common stock and 2,000 shares of Special Voting Preferred Stock pursuant to the Mandatory Repurchase, reducing the outstanding principal amount of the Notes to $162.5 million.  The Notes mature on March 1, 2022, unless earlier repurchased, redeemed or converted in accordance with the terms of the Indenture prior to such date. Interest is payable on the Notes on each March 1, June 1, September 1 and December 1 of each year, commencing June 1, 2017.

The Notes were issued with conversion rights that were subject to receipt of the Requisite Stockholder Approval, which was obtained at a special meeting of stockholders held May 2, 2017.  The Notes are convertible at the option of the holder into shares of common stock based on an initial conversion price of $2.2103 per share, subject to certain adjustments and the issuance of additional “make-whole” shares under certain circumstances specified in the Indenture. Subject to certain limitations, the Company will have the right to settle its conversion obligations on the Notes in common stock, or in cash or a combination thereof.  The Company has the right to redeem the Notes (i) on or after March 3, 2019 if the common stock trades above 150% of the conversion price for periods specified in the Indenture; and (ii) on or after March 1, 2021 without regard to such condition, in each case at par plus accrued interest.

The Notes are secured by a second-priority lien on substantially all of the assets of the Company. The Indenture restricts the ability of the Company and certain of its subsidiaries to, among other things: (i)  pay dividends or make other distributions in respect of the Company’s capital stock or make other restricted payments; (ii) incur additional indebtedness and issue preferred stock; (iii)

54

make certain dispositions and transfers of assets; (iv) engage in transactions with affiliates; (v) create liens; (vi) engage in certain business activities that are not related to oil and gas; and (vii) impair any security interest. These covenants are subject to a number of exceptions and qualifications.

On June 29, 2018, we entered into the Second Supplemental Indenture, which supplements the Indenture.  The Second Supplemental Indenture, among other things, (i) waived certain defaults, (ii) reduced the period the we could cure certain covenant defaults under the Indenture from 60 days to 15 days and (iii) prohibited us and our subsidiary from making cash dividends or distributions on or with respect to our capital stock, other than cash dividends on its Series A Preferred Stock and its Series B Preferred Stock declared for the month of June 2018.

Our voluntary filing of our petition in the Chapter 11 Cases constituted an event of default that accelerated our obligations pursuant to the Notes.  Under the Bankruptcy Code, the creditors under the Notes and other debt agreements are stayed from taking any action against the Company as a result of an event of default.  See “Overview – Recent Developments” above for additional details about the Chapter 11 Cases and the proposed Plan.

Preferred Stock.  Pursuant to Amendment No. 10 to our Revolving Credit Facility, on January 10, 2017, we declared a special cash dividend on the Series A Preferred Stock and Series B Preferred Stock to pay in full all accumulated and unpaid cash dividends since April 1, 2016 at an annualized 8.625% and 10.75%, respectively, which dividend was paid on January 31, 2017.  Under Amendment No. 10 to the Revolving Credit Facility, payment of the declared Series A and Series B Preferred Stock January 2017 dividend and monthly preferred stock cash dividends through May 2017 were permitted.  Dividends on the Series A and Series B Preferred Stock will accumulate regardless of whether any such dividends are declared. The Series A Preferred Stock dividend is a fixed rate of 8.625% per annum of the $25.00 per share liquidation preference, or $2.15625 per share outstanding each year, and on the Series B Preferred Stock a fixed rate of 10.75% per annum of the $25.00 per share liquidation preference, or $2.6875 per share outstanding each year.  If the Company fails to pay full cash dividends in four calendar quarters, whether consecutive or non-consecutive, then the fixed rate of Series A and Series B Preferred Stock each increases by 2.00% and the holders, voting as a single class, will have the right to elect up to two directors to our board of directors.  

On June 29, 2018, we entered into Amendment No. 4 to the Term Loan and into the Second Supplemental Indenture, both of which prohibit us from making cash dividends or distributions on or with respect to our capital stock, other than cash dividends on our Series A Preferred Stock and our Series B Preferred Stock declared for the month of June 2018, which were paid on July 2, 2018.  At September 30, 2018, there were $3.6 million of undeclared cumulative dividends on preferred stock.  

Off-Balance Sheet Arrangements

As of September 30, 2018, we had no off-balance sheet arrangements. We have no plans to enter into any off-balance sheet arrangements in the foreseeable future.

Commitments and Contingencies

As is common within the industry, we have entered into various commitments and operating agreements related to the exploration and development of and production from proved oil and natural gas properties. It is management’s belief that such commitments will be met without a material adverse effect on our financial position, results of operations or cash flows.

We are party to various litigation matters and administrative claims arising out of the normal course of business. Although the ultimate outcome of each of these matters cannot be absolutely determined and the liability the Company may ultimately incur with respect to any one of these matters in the event of a negative outcome may be in excess of amounts currently accrued with respect to such matters, management does not believe any such matters will have a material adverse effect on our financial position, results of operations or cash flows. A discussion of current legal proceedings is set forth in Part I, Item 1. “Financial Statements, Note 13 – Commitments and Contingencies” of this report.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, contingent assets and liabilities and the related disclosures in the accompanying condensed consolidated financial statements. Changes in these estimates and assumptions could materially affect our financial position, results of operations or cash flows. Management considers an accounting estimate to be critical if:

• It requires assumptions to be made that were uncertain at the time the estimate was made; and

55

• Changes in the estimate or different estimates could have a material impact on our consolidated results of operations or financial condition.

Significant accounting policies that we employ and information about the nature of our most critical accounting estimates, our assumptions or approach used and the effects of hypothetical changes in the material assumptions used to develop each estimate are presented in Part I, Item I. “Financial Statements, Note 3 – Summary of Significant Accounting Policies” of this report and in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” included in our 2017 Form 10-K.  As of September 30, 2018, with the exception of the adoption of ASC 606 as discussed in “Financial Statements, Note 3 – Summary of Significant Accounting Policies” of this report, our critical accounting policies were consistent with those discussed in our 2017 Form 10-K.  

Recent Accounting Developments

For a discussion of recent accounting developments, see Part I, Item 1. “Financial Statements, Note 3 – Summary of Significant Accounting Policies” of this report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risk. The term “market risk” refers to the risk of loss arising from adverse changes in natural gas, NGLs, and oil prices, and interest rates.  The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. This forward-looking information provides indicators of how we viewand manage our ongoing market risk exposures. All of our market risk sensitive instruments were entered into for hedging purposes, rather than for speculative trading.

Commodity Price Risk

Our major commodity price risk exposure is to the prices received for our oil, condensate, natural gas and NGLs production. Our results of operations and operating cash flows are affected by changes in market prices. Realized commodity prices received for our production are the spot prices applicable to oil, condensate, natural gas and NGLs in the region produced. Prices received for oil, condensate, natural gas and NGLs are volatile and unpredictable and are beyond our control.  To mitigate a portion of our exposure to adverse market changes in the prices for oil, condensate, natural gas and NGLs, we historically have entered into and may in the future enter into additional commodity price risk management arrangements for a portion of our oil, condensate, natural gas and NGLs production.  For the three months ended September 30, 2018, a 10% change in the prices received for oil, condensate, natural gas and NGLs production would have had an approximate $2.2 million impact on our revenues prior to hedge transactions to mitigate our commodity pricing risk. For the three months ended September 30, 2017, a 10% change in the prices received for our oil, condensate, natural gas and NGLs production would have had an approximate $1.8 million impact on our revenues prior to hedge transactions to mitigate our commodity pricing risk.  For the nine months ended September 30, 2018, a 10% change in the prices received for oil, condensate, natural gas and NGLs production would have had an approximate $6.7 million impact on our revenues prior to hedge transactions to mitigate our commodity pricing risk.  For the nine months ended September 30, 2017, a 10% change in the prices received for oil, condensate, natural gas and NGLs production would have had an approximate $5.3 million impact on our revenues prior to hedge transactions to mitigate our commodity pricing risk.  As of September 30, 2018, the fair market value of our commodity derivatives was a net liability of $15.8 million.  As of December 31, 2017, the fair market value of our commodity derivatives was a net liability of $5.6 million.  For more information regarding our hedging activities, see Part I, Item 1. “Financial Statements, Note 8 – Derivative Instruments and Hedging Activity” of this report for additional information regarding our hedging activities.

On October 26, 2018, we and the Hedge Parties entered into the Hedge Party RSA to effectively terminate our current hedge positions and replace such with the Hedge Party Secured Notes.  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties described above.  The Hedge Party RSA contains certain covenants on the part of each of the Company and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements.  The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.  The Hedge Party Secured Notes will be secured by an uncapped first priority security interest in the collateral that secures the Exit Facility which security interest and lien shall rank pari passu with the liens granted to our senior-most creditors (with respect to debt for borrowed money).  The Hedge Party Secured Notes mature on December 31, 2019 during which time no interest shall accrue unless a default occurs under the terms thereof.  Funds in the Exit Facility will be available to make payments under the Hedge Party Secured Notes.

56

Interest Rate Risk

Prior to the pay-off of our Revolving Credit Facility in March 2017, we were exposed to changes in interest rates as a result of our Revolving Credit Facility.  We did not enter into interest rate hedging arrangements in the past.  The amount outstanding under the Term Loan was fixed at interest of 8.5% per annum prior to June 30, 2017 and is fixed at 10.25% per annum after June 30, 2017 and the amount outstanding under the Notes is at fixed interest of 6.0% per annum.   Thus, under our current debt facilities, we have no exposure to fluctuating interest rates.  Under the contemplated DIP Facility, we will be exposed to changes in interest rates as amounts outstanding under the DIP Facility will bear interest at a rate per annum equal to the adjusted LIBO rate plus the applicable margin in effect from time to time.    

Item 4. Controls and Procedures

Management’s Evaluation on the Effectiveness of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Interim Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), as of September 30, 2018. Based on that evaluation, our Interim Chief Executive Officer and Chief Financial Officer concluded that, due to the material weakness described below, as of September 30, 2018, our disclosure controls and procedures were not effective in providing reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Interim Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.  

Changes in Internal Control Over Financial Reporting

During the quarter ended June 30, 2018, an error was discovered in determining the Company’s compliance with its debt covenants under the Company’s secured Term Loan and Indenture under which the Company’s outstanding secured Notes are issued. The failure to comply with these debt covenants resulted in defaults under both the Term Loan and Indenture, which defaults were subsequently waived on June 29, 2018. This error, which was not detected timely by management, was the result of inadequate understanding of the covenants under the Term Loan and Indenture, and there is a reasonable possibility that the error could have resulted in a material misstatement of the financial statements.  This inability to accurately monitor compliance with such debt covenants is a deficiency which represents a material weakness in the Company’s internal control over financial reporting.  A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

To address the material weakness described above, the Company is in the process of implementing new and enhanced controls to ensure that the quarterly debt covenant analysis and calculations are performed correctly and reviewed appropriately.

We believe the actions described above will be sufficient to remediate the identified material weakness and strengthen our internal control over financial reporting.  We will continue to monitor the effectiveness of these controls and will make any further changes management determines appropriate.  

Except for the Company’s design and implementation of new and enhanced controls related to the material weakness described above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended September 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

57

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

A discussion of current legal proceedings is set forth in Part I, Item 1. “Financial Statements, Note 13 – Commitments and Contingencies” of this report which is incorporated herein by reference.

Item 1A. Risk Factors

In addition to the risk factors below and the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our 2017 Form 10-K, which could materially affect our business, financial condition or future results. These risks are not the only risks facing our Company.  Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, operating results and cash flows.  

We are subject to risks and uncertainties associated with our Chapter 11 proceedings.

Our operations and ability to develop and execute our business plan, our financial condition, our liquidity and our continuation as a going concern, are subject to the risks and uncertainties associated with our Chapter 11 proceedings. These risks include the following:

• our ability to execute, confirm and consummate the Plan or another plan of reorganization with respect to the Chapter 11 proceedings;

• the high costs of bankruptcy proceedings and related fees;

• our ability to obtain sufficient financing to allow us to emerge from bankruptcy and execute our business plan post-emergence;

• our ability to maintain our relationships with our suppliers, service providers, customers, employees, and other third parties;

• our ability to maintain contracts that are critical to our operations;

• our ability to execute our business plan in the current depressed commodity price environment;

• our ability to attract, motivate and retain key employees;

• the ability of third parties to seek and obtain court approval to terminate contracts and other agreements with us;

• the ability of third parties to seek and obtain court approval to convert the Chapter 11 proceedings to a Chapter 7 proceeding; and

• the actions and decisions of our creditors and other third parties who have interests in our Chapter 11 proceedings that may be inconsistent with our plans.

Delays in our Chapter 11 proceedings increase the risks of us being unable to reorganize our business and emerge from bankruptcy and increase our costs associated with the bankruptcy process.

These risks and uncertainties could affect our business and operations in various ways. For example, negative events or publicity associated with our Chapter 11 proceedings could adversely affect our relationships with our suppliers, service providers, customers, employees, and other third parties, which in turn could adversely affect our operations and financial condition. Also, pursuant to the Bankruptcy Code, we need the prior approval of the Bankruptcy Court for transactions outside the ordinary course of business, which may limit our ability to respond timely to certain events or take advantage of certain opportunities. We also need Bankruptcy Court confirmation of the Plan. Because of the risks and uncertainties associated with our Chapter 11 proceedings, we cannot accurately predict or quantify the ultimate impact that events that occur during our Chapter 11 proceedings will have on our business, financial condition and results of operations, and there is no certainty as to our ability to continue as a going concern.

The RSA is subject to significant conditions and milestones that may be difficult for the Company to satisfy.

There are certain material conditions we must satisfy under the RSA, including the timely satisfaction of milestones in the Chapter 11 Cases, such as confirmation of the Plan and effectiveness of the Plan. Our ability to timely complete such milestones is subject to risks and uncertainties that may be beyond our control.

58

If the RSA is terminated, our ability to confirm and consummate the Plan substantially as proposed in the RSA could be materially and adversely affected.

The RSA contains a number of termination events, upon the occurrence of which certain parties to the RSA may terminate the agreement.  If the RSA is terminated, each of the parties thereto will be released from their obligations in accordance with the terms of the RSA.  Such termination may result in the loss of support for the Plan by the parties to the RSA, which could adversely affect our ability to confirm and consummate the Plan.  If the Plan is not consummated substantially as proposed in the RSA, there can be no assurance that any new plan would be as favorable to holders of claims as the current Plan.

We may not be able to obtain confirmation of a Chapter 11 plan of reorganization.

To emerge successfully from Bankruptcy Court protection as a viable entity, we must meet certain statutory requirements with respect to adequacy of disclosure with respect to a Chapter 11 plan of reorganization, solicit and obtain the requisite acceptances of such a reorganization plan and fulfill other statutory conditions for confirmation of such a plan. However, even if our plan meets other requirements under the Bankruptcy Code, certain parties in interest may file objections to the Plan in an effort to persuade the Bankruptcy Court that we have not satisfied the confirmation requirements under section 1129 of the Bankruptcy Code. Even if no objections are filed and the requisite acceptances of our Plan are received from creditors entitled to vote on the Plan, the Bankruptcy Court, which can exercise substantial discretion, may not confirm the Plan. The precise requirements and evidentiary showing for confirming a plan, notwithstanding its rejection by one or more impaired classes of claims or equity interests, depends upon a number of factors including, without limitation, the status and seniority of the claims or equity interests in the rejecting class (i.e., secured claims or unsecured claims, subordinated or senior claims, preferred or common stock).

If the Plan is not confirmed by the Bankruptcy Court, it is unclear whether we would be able to reorganize our business and what, if anything, holders of claims against us would ultimately receive with respect to their claims.

Even if a Chapter 11 Plan of Reorganization is consummated, we may not be able to achieve our stated goals and continue as a going concern.

Even if the Plan or another Chapter 11 plan of reorganization is consummated, we will continue to face a number of risks, including further deterioration in commodity prices or other changes in economic conditions, changes in our industry, changes in demand for our oil and gas and increasing expenses. Accordingly, we cannot guarantee that the Plan or any other Chapter 11 plan of reorganization will achieve our stated goals.

Furthermore, even if our debts are reduced or discharged through the Plan, we may need to raise additional funds through public or private debt or equity financing or other various means to fund our business after the completion of our Chapter 11 proceedings. Our access to additional financing is, and for the foreseeable future will likely continue to be, extremely limited, if it is available at all. Therefore, adequate funds may not be available when needed or may not be available on favorable terms, if they are available at all.

Our ability to continue as a going concern is dependent upon our ability to raise additional capital. As a result, we cannot give any assurance of our ability to continue as a going concern, even if the Plan is confirmed.

Any plan of reorganization that we may implement will be based in large part upon assumptions and analyses developed by us. If these assumptions and analyses prove to be incorrect, our Plan may be unsuccessful in its execution.

Any plan of reorganization that we may implement could affect both our capital structure and the ownership, structure and operation of our businesses and will reflect assumptions and analyses based on our experience and perception of historical trends, current conditions and expected future developments, as well as other factors that we consider appropriate under the circumstances. Whether actual future results and developments will be consistent with our expectations and assumptions depends on a number of factors, including but not limited to (i) our ability to change substantially our capital structure; (ii) our ability to obtain adequate liquidity and financing sources; (iii) our ability to maintain customers’ confidence in our viability as a continuing entity and to attract and retain sufficient business from them; (iv) our ability to retain key employees, and (v) the overall strength and stability of general economic conditions of the financial and oil and gas industries, both in the U.S. and in global markets. The failure of any of these factors could materially adversely affect the successful reorganization of our businesses.

In addition, any plan of reorganization will rely upon financial projections, including with respect to revenues, EBITDA, capital expenditures, debt service and cash flow. Financial forecasts are necessarily speculative, and it is likely that one or more of the assumptions and estimates that are the basis of these financial forecasts will not be accurate. In our case, the forecasts will be even

59

more speculative than normal, because they may involve fundamental changes in the nature of our capital structure. Accordingly, we expect that our actual financial condition and results of operations will differ, perhaps materially, from what we have anticipated. Consequently, there can be no assurance that the results or developments contemplated by any plan of reorganization we may implement will occur or, even if they do occur, that they will have the anticipated effects on us and our subsidiaries or our businesses or operations. The failure of any such results or developments to materialize as anticipated could materially adversely affect the successful execution of any plan of reorganization.

We have substantial liquidity needs and may not be able to obtain sufficient liquidity to confirm a plan of reorganization and exit bankruptcy.

Although we have lowered our capital budget and reduced the scale of our operations significantly, our business remains capital intensive. In addition to the cash requirements necessary to fund ongoing operations, we have incurred significant professional fees and other costs in connection with our Chapter 11 proceedings and expect that we will continue to incur significant professional fees and costs throughout our Chapter 11 proceedings. We do not believe that our cash on hand and our cash flow from operations will be sufficient to continue to fund our operations for any significant period of time. There are no assurances that our current liquidity is sufficient to allow us to satisfy our obligations related to the Chapter 11 proceedings, allow us to proceed with the confirmation of a Chapter 11 plan of reorganization and allow us to emerge from bankruptcy. We can provide no assurance that we will be able to secure additional interim financing or exit financing sufficient to meet our liquidity needs or, if sufficient funds are available, offered to us on acceptable terms.

In certain instances, a Chapter 11 case may be converted to a case under Chapter 7 of the Bankruptcy Code.

Upon a showing of cause, the Bankruptcy Court may convert our Chapter 11 Cases to  cases under Chapter 7 of the Bankruptcy Code. In such event, a Chapter 7 trustee would be appointed or elected to liquidate our assets and the assets of our subsidiary for distribution in accordance with the priorities established by the Bankruptcy Code. We believe that liquidation under Chapter 7 would result in significantly smaller distributions being made to our creditors than those provided for in our Plan because of (i) the likelihood that the assets would have to be sold or otherwise disposed of in a distressed fashion over a short period of time rather than in a controlled manner and as a going concern, (ii) additional administrative expenses involved in the appointment of a Chapter 7 trustee, and (iii) additional expenses and claims, some of which would be entitled to priority, that would be generated during the liquidation and from the rejection of leases and other executory contracts in connection with a cessation of operations.

Our common stock has been suspended from trading on the NYSE American, ceased to be listed on a national securities exchange effective September 7, 2018, and is traded only in the over-the-counter market, which could negatively affect our stock price and liquidity.

On September 6, 2018, the Company received a letter from the NYSE American Staff (the “Staff”) stating that the Staff has determined that the Company’s securities will be delisted from the NYSE American. The decision was reached by the Staff under NYSE American Listing Rule 12d2-2(b) as a result of the Company’s common stock trading below $0.06. The letter further indicated that, unless the Company requests an appeal, trading of the Company’s common stock was suspended immediately on September 6, 2018, and a Form 25-NSE was subsequently filed with the SEC, which would remove the Company’s securities from listing and registration on the NYSE American. The Company did not appeal the NYSE American’s determination and began quotation on the OTCQB.

Upon the filing of our voluntary petition in the Chapter 11 Cases, our securities became quoted on the OTC Markets Group Inc.’s OTC Pink (the “OTC Pink”). The OTC Pink is a significantly more limited market than the NYSE American, and the quotation of our common stock on the OTC Pink may result in a less liquid market available for existing and potential shareholders to trade shares of our common stock. This could further depress the trading price of our common stock and could also have a long-term adverse effect on our ability to raise capital. There can be no assurance that any public market for our common stock will exist in the future or that we will be able to relist our common stock on a national securities exchange. In connection with the delisting of our common stock, there may also be other negative implications, including the potential loss of confidence in the Company by suppliers, customers and employees and the loss of institutional investor interest in our common stock.

We believe it is highly likely that the shares of our existing common stock will be canceled in our Chapter 11 proceedings.

The RSA contemplates that our outstanding indebtedness will be converted into equity of the reorganized Company and that the existing common stock of the Company may be converted into warrants to purchase shares of common stock upon our emergence from bankruptcy.  Even if the Plan is confirmed as currently set forth in the RSA, the value of any warrants that are issued is highly speculative and the exercise prices of such warrants will be based upon assumed equity values that may never be attained.

60

We may be subject to claims that will not be discharged in our Chapter 11 proceedings, which could have a material adverse effect on our financial condition and results of operations.

The Bankruptcy Code provides that the confirmation of a Chapter 11 plan of reorganization discharges a debtor from substantially all debts arising prior to confirmation. With few exceptions, all claims that arose prior to confirmation of the plan of reorganization (i) would be subject to compromise and/or treatment under the plan of reorganization and (ii) would be discharged in accordance with the Bankruptcy Code and the terms of the plan of reorganization. Any claims not ultimately discharged through a Chapter 11 plan of reorganization could be asserted against the reorganized entities and may have an adverse effect on our financial condition and results of operations on a post-reorganization basis.

Our financial results may be volatile and may not reflect historical trends.

During the Chapter 11 proceedings, we expect our financial results to continue to be volatile as asset impairments, asset dispositions, restructuring activities and expenses, contract terminations and rejections, and claims assessments may significantly impact our consolidated financial performance. As a result, our historical financial performance is likely not indicative of our financial performance after the Petition Date.

In addition, if we emerge from Chapter 11, the amounts reported in subsequent consolidated financial statements may materially change relative to historical consolidated financial statements, including as a result of revisions to our operating plans pursuant to a plan of reorganization. We also may be required to adopt fresh start accounting, in which case our assets and liabilities will be recorded at fair value as of the fresh start reporting date, which may differ materially from the recorded values of assets and liabilities on our consolidated balance sheets. Our financial results after the application of fresh start accounting also may be different from historical trends.

The pursuit of the Chapter 11 proceedings has consumed and will continue to consume a substantial portion of the time and attention of our management and will impact how our business is conducted, which may have an adverse effect on our business and results of operations.

A long period of operating under Chapter 11 could adversely affect our business and results of operations. While the Chapter 11 proceedings continue, our senior management will be required to spend a significant amount of time and effort focusing on the proceedings. This diversion of attention may materially affect the conduct of our business adversely, and, as a result, on our financial condition and results of operations, particularly if the Chapter 11 Cases are protracted.

We may not meet certain conditions of the RSA, which could result in the automatic termination of such agreement, which could adversely affect us and our stakeholders and creditors.

We entered into the RSA on October 26, 2018. We may not be able to meet certain conditions of the RSA, which could cause the automatic termination of the RSA.  If the RSA were terminated, our operation under Chapter 11 could be significantly extended requiring more time of our management and the occurrence by us of significant additional costs, and our stakeholders and creditors would be subject to substantially more uncertainty as to the outcome of the Chapter 11 proceeding.  

We may not be able to continue as a going concern.

We have substantial debt obligations and our ongoing operations have historically been dependent upon spending significant capital on drilling and development of our properties.  Our ability to raise additional capital to pursue corporate objectives such as a drilling and development program at a cost of capital that enables our business to achieve a profit has been significantly adversely affected by our current capital structure.  We do not believe we have the ability to reduce capital expenditures further without creating the potential for deterioration of our core business.  We are pursuing a restructuring as set forth in the Plan and the RSA.  There can be no assurance that we will consummate the transactions contemplated by the Plan and the RSA on a timely basis.

The condensed consolidated financial statements included in this report have been prepared assuming that we will continue as a going concern and do not include any adjustments that might result from the outcome of the going concern uncertainty.  If we cannot continue as a going concern, adjustments to the carrying values and classification of our assets and liabilities and reported amounts of income and expenses could be required and could be material.  There can be no assurance that we will be able to obtain additional funding on a timely basis and on satisfactory terms, or at all.   In addition, no assurance can be given that any such funding, if obtained, will be adequate to meet our capital needs and support our business plan while paying or refinancing our existing debt obligations.   If additional funding cannot be obtained on a timely basis and on satisfactory terms, then our operations would be materially negatively impacted.

61

We have identified material weaknesses in our internal control over financial reporting and may identify additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls.

We are required to maintain internal control over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles.  During the quarter ended June 30, 2018, we and our independent registered public accounting firm identified material weaknesses in internal control over financial reporting relating to the inability to monitor compliance with the Company’s covenants under the Company’s Term Loan and Indenture.  A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. See Part I, Item 4.  “Controls and Procedures” in this report.

            We are in the process of remediating the identified material weakness through the design and implementation of new and enhanced controls.  However, we do not expect that our internal control over financial reporting, including these enhanced controls, will prevent all future errors and all fraud.  A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met.  Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.  Over time, controls may become inadequate because changes in conditions or deterioration in the degree of compliance with policies or procedures may occur.  Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.  Our failure to maintain effective internal control over financial reporting could result in errors in our financial statements that could result in a restatement of our financial statements and cause us to fail to meet our reporting obligations.  Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

July 1, 2018 – July 31, 2018	67,142	$0.10	—	n/a
August 1, 2018 – August 31, 2018	37,876	$0.17	—	n/a

Item 3. Defaults Upon Senior Securities

The Company’s voluntary filing for proceedings under Chapter 11 of the Bankruptcy Code on October 31, 2018 constituted an event of default that accelerated the Company’s obligations under its Term Loan and its Notes.  Under the Bankruptcy Code, the creditors under the Term Loan and the Notes are stayed from taking any action against the Company and its subsidiary as a result of an event of default.  See Part I, Item 1. “Financial Statements, Note 2 – Going Concern” of this report for more information concerning the Chapter 11 Cases and the proposed Plan.  

The Company discontinued the payment of dividends on its outstanding shares of Series A Preferred Stock and Series B Preferred Stock for periods after June 30, 2018.  As of September 30, 2018, cumulative unpaid dividends were approximately $2.2 million for the Series A Preferred Stock and $1.4 million for the Series B Preferred Stock.  

Item 4. Mine Safety Disclosure

Not applicable.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Going Concern

2. Going Concern

These unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2018 have been prepared assuming the Company will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of issuance of these condensed consolidated financial statements.    

As previously reported, the Company’s ability to raise additional capital to pursue corporate objectives such as a drilling and development program at a cost of capital that enables the Company to achieve a profit has been significantly adversely affected by its current capital structure. While, historically, the Company has been able to reduce capital expenditures to better match available capital resources, for the reasons described below, the Company has reduced capital expenditures by suspending its operated drilling program.  A sustained suspension of the operated drilling program could create the potential for deterioration of its core business.  In addition, as a result of the recent further significant deterioration of the Company’s equity trading values, the Company’s common and preferred stock were delisted from the NYSE American LLC stock exchange (the “NYSE American”) and began trading on the OTCQB Venture Market (“OTCQB”).  Upon the filing of the Company’s petition for voluntary relief under Chapter 11 of the United States Bankruptcy Code (as described below), the Company’s common and preferred stock were automatically removed from quotation on the OTCQB.  The Company’s common and preferred stock commenced trading on the OTC Pink Operated by the OTC Markets Group Inc. (also known as the “OTC Pink”) under the same symbols.

To address the foregoing concerns, the Company and its advisors have considered strategic alternatives for recommendation to the board of directors (the “Board”) of the Company.  In connection with developing and evaluating alternatives for the Board, the Company and its advisors engaged in a restructuring process to consider potential strategic transactions, including financing, refinancing, sale or merger transactions and encouraged proposals from existing stakeholders and interested third-parties.  The Company also elected to suspend its current operated drilling and development program in order to preserve capital for other cash needs including debt service while it considered other strategic alternatives or a possible restructuring of the Company’s debt and equity.    

On August 21, 2018, the Company publicly filed a process letter that again invited proposals and informed the public how any interested party could participate and make a proposal.  The process letter established the bid deadline of October 1, 2018 (the “Bid Deadline”).  The Company received three bids on the Bid Deadline, none of which provided a basis for repaying the Company’s indebtedness described below.  The Company’s Board determined that none of these proposals presented an actionable alternative.

In parallel with the foregoing marketing process, the Company engaged with funds affiliated with Ares regarding a comprehensive financial restructuring transaction.  On October 26, 2018, the Company entered into a restructuring support agreement (the “RSA”) with (i) AF V Energy I Holdings, L.P., an affiliate of Ares (the “Consenting Term Lender”) and party to the Third Amended and Restated Credit Agreement, dated March 3, 2017 (as amended, restated, modified, or supplemented form time to time, the “Term Loan”) (ii) certain holders affiliated with Ares (the “Consenting Noteholders”) of the Company’s Convertible Notes due 2022 (the “Notes”) issued pursuant to the indenture dated March 3, 2017 (as amended, restated, modified or supplemented from time to time, the “Indenture”), by and among the Company, as issuer, the guarantors specified therein and Wilmington Trust, National Association, as trustee (the “Trustee”) and collateral agent and (iii) certain holders affiliated with Ares (the “Ares Equity Holders” together with the Consenting Term Lender and the Consenting Noteholders, the “Consenting Parties”) of the Company’s outstanding shares of common stock (the “Existing Common Equity”), to support a restructuring (the “Restructuring”) on the terms set forth in the term sheet annexed to the RSA (the “Restructuring Term Sheet”).  The RSA contemplates that the Company and a subsidiary would file for voluntary relief under chapter 11 (the “Chapter 11 Cases”) of the United States Bankruptcy Code (the “Bankruptcy Code”) in a United States Bankruptcy Court (the “Bankruptcy Court”) to implement the Restructuring pursuant to a “prepackaged” plan of reorganization (the “Plan”) and the various related transactions set forth in or contemplated by the Restructuring Term Sheet, the DIP Term Sheet (defined below) and the Exit Facility Term Sheet (defined below).  Shortly after entering into the RSA, the Company commenced solicitation of the Plan consistent with section 1126(b) of the Bankruptcy Code, which solicitation concluded on October 30, 2018.    

On October 31, 2018 (the “Petition Date”), the Company and a subsidiary commenced chapter 11 proceedings and filed the Plan under Chapter 11 of the Bankruptcy Code in the Bankruptcy Court. The Company has filed a motion with the Bankruptcy Court seeking joint administration of their Chapter 11 Cases.  The Company will continue to operate its businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. The Company expects ordinary-course operations to continue substantially uninterrupted during and after the Chapter 11 Cases.

Pursuant to the terms of the RSA and the Restructuring Term Sheet, the Consenting Parties and other interest holders will receive treatment under the Plan summarized as follows:

• holders of claims under the DIP Facility (defined below) arising on account of the New Money Loans (defined below) will receive pro rata participation in the First Lien Exit Facility (defined below) in an amount equal to such claims arising on account of New Money Loans;  

• holders of claims under the DIP Facility, other than claims arising on account of the New Money Loans, will receive (a) pro rata participation in the Second Lien Exit Facility (defined below) up to an aggregate amount of $200.0 million and (b) to the extent any such claims exceed $200.0 million, such excess will receive a pro rata share of 100% of the common equity in the reorganized Company (the “New Common Equity”);

• holders of claims under the Term Loan will receive (a) to the extent there is remaining availability under the Second Lien Exit Facility, pro rata participation in the Second Lien Exit Facility in an equal face amount not to exceed $200.0 million and (b) to the extent any such claims remain outstanding, their pro rata share of 100% of the New Common Equity, subject to dilution upon the issuance of common stock upon exercise of the New Warrants described below and pursuant to a new management incentive plan to be entered into at the discretion of the board of the reorganized Company following emergence from bankruptcy (the “Management Incentive Plan”);

• holders of claims under the Indenture will receive their  pro rata share of 100% of the New Common Equity, subject to dilution upon the issuance of common stock upon exercise of the New Warrants described below and pursuant to the Management Incentive Plan;

• holders of claims arising out of any termination of the Company’s hedging or swap arrangements with Cargill, Inc. and NextEra Energy Marketing, LLC (collectively, the “Hedge Parties”) will receive payment in full in cash in monthly installments through December 2019 pursuant to new secured notes;

• holders of claims arising pursuant to statutory liens will receive payment in full in cash in two equal installments on the effective date of the Chapter 11 Cases and six months following such date;

• holders of claims arising from general unsecured obligations will receive payment in full in cash as set forth in the Plan;

• subject to certain conditions, including that such holders not seek official committee status or the appointment of a trustee or examiner, or object to or otherwise oppose the consummation of the Plan, holders of Gastar’s 8.625% Series A Cumulative Preferred Stock and 10.75% Series B Cumulative Preferred Stock (collectively, the “Existing Preferred Equity”) will receive their pro rata share based on their liquidation preference plus accumulated but unpaid dividends accrued through October 31, 2018 of warrants to purchase 2.5% of the New Common Equity; and

• subject to certain conditions, including that such holders not seek official committee status or the appointment of a trustee or examiner, or object to or otherwise oppose the consummation of the Plan, holders of the Existing Common Equity will receive their pro rata share of warrants to purchase 2.5% of the New Common Equity (together with the warrants listed in the previous bullet, the “New Warrants”).

In the event that a DIP Toggle Event (as defined in the Restructuring Term Sheet) has occurred, (i) holders of claims arising from general unsecured obligations will receive a pro rata share of the New Common Equity and (ii) all Existing Preferred Equity and Existing Common Equity and Subordinated Securities Claims will be canceled, released, and extinguished without distribution.  The occurrence of a DIP Toggle Event will not affect the other treatments contemplated by the RSA as listed above.

The RSA contains certain covenants on the part of each of the Company and the Consenting Parties, including limitations on the parties’ ability to pursue alternative transactions, commitments by the Consenting Parties to vote in favor of the Plan and commitments of the Company and the Consenting Parties to negotiate in good faith to finalize the documents and agreements governing the Plan. The RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the RSA.

On October 26, 2018, the Company and the Hedge Parties entered into that certain Hedge Party Restructuring Support Agreement (the “Hedge Party RSA”).  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties described above.  The Hedge Party RSA contains certain covenants on the part of each of the Company and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements. The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, the Company with superpriority debtor-in-possession financing (the “DIP Facility”) on the terms set forth in the term sheet attached to the RSA (the “DIP Term Sheet”). The DIP Term Sheet provides that, among other things:

• the DIP Facility shall be comprised of term loans in an aggregate amount of approximately $383.9 million, consisting of $100 million of new money loans (the “New Money Loans”) and approximately $283.9 million of refinanced term loan obligations outstanding under the Term Loan;

• upon entry of and subject to a Bankruptcy Court order granting interim approval of the DIP Facility and subject to the satisfaction or waiver of additional conditions precedent, up to $15.0 million of the New Money Loans (the “Interim DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount that is not less than $2.5 million for the initial draw and not less than $500,000 for each subsequent draw (or, if less, the entire amount of the unused balance of the Interim DIP Tranche);

• upon entry of and subject to a Bankruptcy Court order granting final approval (the “Final Order”) of the DIP Facility, and subject to the satisfaction or waiver of additional conditions precedent and an approved budget, up to $100.0 million of New Money Loans, minus any amounts of New Money Loans previously drawn by the Company prior to such date (the resulting amount, the “Final DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Final DIP Tranche);

• upon entry of and subject to the Final Order and subject to the satisfaction or waiver of additional conditions precedent, including the Company having demonstrated to the reasonable satisfaction of the DIP Lenders acting in good faith, the bona fide need for additional liquidity to preserve lease operating rights in response to actions taken or proposed to be taken by third parties, an amount equal to $100.0 million minus the amount of New Money Loans previously drawn by the Company prior to such date (the resulting amount, the “Reserve DIP Tranche”) may be drawn by the Company upon three business days’ notice in one or more draws in an amount not less than $500,000 for each draw (or, if less, in the entire amount of the unused balance of the Reserve DIP Tranche); and

• subject to entry of the Final Order, approximately $283.9 million in outstanding term loan obligations consisting of principal and accrued and unpaid interest under the Term Loan as of the date of the commencement of the Chapter 11 Cases will be refinanced by loans (not constituting New Money Loans) funded under the DIP Facility.

The Company’s entry into the DIP Facility has been approved by the Bankruptcy Court on an interim basis. The Company’s entry into the DIP Facility on a final basis will be considered by the Bankruptcy Court at a future date.  The foregoing description of the DIP Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the DIP Facility, as approved by the Bankruptcy Court.

In connection with the Chapter 11 Cases, certain Consenting Parties and/or their affiliates have agreed to provide, on a committed basis, the Company with an exit financing term loan facility (the “Exit Facility”) on the terms set forth in the term sheet attached to the RSA (the “Exit Facility Term Sheet”). The Exit Facility Term Sheet provides for, among other things, (a) a $100.0 million secured delayed draw term loan facility (the “First Lien Exit Facility”) comprised of (i) term loans consisting of New Money Loans funded under the DIP Facility and deemed funded under the First Lien Exit Facility on the effective date of the Plan and (ii) term loan commitments consisting of an amount equal to any undrawn commitment under the DIP Facility and (b) a secured term loan facility (the “Second Lien Exit Facility”) comprised of up to $200.0 million (as may be reduced by the Exit Lenders in their sole discretion on or prior to the effective date of the Plan), in aggregate principal amount of term loans deemed funded on the effective date of the Plan and consisting of DIP Claims and Term Loan Claims (each as defined in the RSA), as applicable (the loans under the First Lien Exit Facility and the Second Lien Exit Facility, collectively, the “Exit Loans”).  The Exit Loans may not be reborrowed once repaid.

The Exit Facility is subject to customary closing conditions and approval by the Bankruptcy Court, which has not been obtained at this time. The foregoing description of the Exit Facility Term Sheet does not purport to be complete and is qualified in its entirety by reference to the final, executed documents memorializing the Exit Facility, as approved by the Bankruptcy Court.

The Company’s filing of its petition for voluntary relief under Chapter 11 of the Bankruptcy Code constitutes an event of default that accelerated the Company’s obligations under its Term Loan and its Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default.  The transactions described and contemplated by the Plan are all subject to the Bankruptcy Court approval at a future date.  There can be no assurances the Bankruptcy Court will ultimately approve the transaction as described above.

The Company intends to complete a supplemental marketing process seeking proposal for transactions that are higher and better than the transactions contemplated by the Plan during the Chapter 11 Cases, with a bid deadline of December 17, 2018.  The Company intends to publicly disclose further details regarding the supplemental marketing process, including informing interested parties how they may participate and make a proposal, at a future date.  In the absence of a higher or better proposal, the Company intends to seek confirmation of the Plan at a hearing currently scheduled for December 20, 2018.

Voluntary Reorganization Under Chapter 11

On October 31, 2018, the Company and its subsidiary (collectively, the “Debtors”) commenced Chapter 11 proceedings and filed the Plan for reorganization under Chapter 11 of the Bankruptcy Code with the Bankruptcy Court for the Southern District of Texas.  The Debtors have filed a motion with the Bankruptcy Court seeking joint administration of their Chapter 11 Cases under the caption In re: Gastar Exploration Inc., et al.

Subject to certain exceptions, under the Bankruptcy Code, the filing of the petitions for voluntary relief in the Chapter 11 Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover, collect or secure a claim arising prior to the date of the filing of the petitions.  Accordingly, although the filing of the voluntary petitions triggered defaults on the Debtors’ debt obligations, creditors are stayed from taking any actions against the Debtors as a result of such defaults, subject to certain limited exceptions permitted by the Bankruptcy Code.  Absent an order of the Bankruptcy Court, substantially all of the Debtors’ pre-petition liabilities are subject to settlement under the Bankruptcy Code.

For the duration of the Chapter 11 Cases, the Company’s operations and ability to develop and execute its business plan are subject to the risks and uncertainties associated with the Chapter 11 process.  As a result of these risks and uncertainties, the number of the Company’s shares of common stock and stockholders, assets, liabilities, officers and/or directors could be significantly different following the outcome of the Chapter 11 Cases, and the description of the Company’s operations, properties and capital plans included in this quarterly report may not accurately reflect its operations, properties and capital plans following the Chapter 11 process.

In particular, subject to certain exceptions, under the Bankruptcy Code, the Debtors may assume, assign or reject certain executory contracts and unexpired leases subject to the approval of the Bankruptcy Court and certain other conditions.  Generally, the rejection of an executory contract or unexpired lease is treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves the Debtors of performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed breach.  Counterparties to such rejected contracts or leases may assert unsecured claims in the Bankruptcy Court against the applicable Debtors’ estate for such damages.  Generally, the assumption of an executory contract or unexpired lease requires the Debtors to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance.  Accordingly, any description of an executory contract or unexpired lease with the Debtor in this quarterly report, including where applicable a quantification of the Company’s obligations under any such executory contract or unexpired lease with the Debtor is qualified by any overriding rejection rights the Company has under the Bankruptcy Code.  Further, nothing herein is or shall be deemed an admission with respect to any claim amounts or calculations arising from the rejection of any executory contract or unexpired lease and the Debtors expressly preserve all of their rights with respect thereto.

Although the Company intends to pursue the restructuring in accordance with the terms set forth in the Plan and the RSA, the transactions necessary to implement that restructuring are subject to, among other things, Bankruptcy Court approval, and there can be no assurance that the Company will be successful in completing a restructuring or any other similar transaction on the terms set forth in the Plan and the RSA, on different terms or at all.  

Furthermore, although the Company will continue to operate its businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court, these factors raise substantial doubt about the Company’s ability to continue as a going concern.  These unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of the going concern uncertainty.  If the Company cannot continue as a going concern, adjustments to the carrying values and classification of its assets and liabilities and the reported amounts of income and expenses could be required and could be material.

Please refer to the notes to the consolidated financial statements included in the 2017 Form 10-K for additional details of the Company’s financial condition, results of operations and cash flows. No material item included in those notes has changed except as a result of normal transactions in the interim or as disclosed within this report.

The unaudited interim condensed consolidated financial statements of the Company included herein are stated in U.S. dollars and were prepared from the records of the Company by management in accordance with U.S. GAAP applicable to interim financial statements and reflect all normal and recurring adjustments, which are, in the opinion of management, necessary to provide a fair presentation of the results of operations and financial position for the interim periods. Such financial statements conform to the presentation reflected in the 2017 Form 10-K except for revenue which, for the three and nine months ended September 30, 2018, is presented net of treating, transportation and gathering costs pursuant to current authoritative accounting guidance. The current interim period reported herein should be read in conjunction with the financial statements and accompanying notes, including Item 8. “Financial Statements and Supplementary Data, Note 3 – Summary of Significant Accounting Policies,” included in the 2017 Form 10-K.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates with regard to these financial statements include the valuation of convertible debt, estimate of proved oil and natural gas reserve quantities and the related present value of estimated future net cash flows.

The unaudited interim condensed consolidated financial statements of the Company include the consolidated accounts of all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018.

Subsequent Events

In preparing these financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued and has disclosed certain subsequent events in these condensed consolidated financial statements, as appropriate.

Restricted Cash

Cash and cash equivalents that are restricted as to withdrawal or use under the terms of certain contractual agreements are recorded in restricted cash in the current assets section of our consolidated balance sheet.  At September 30, 2018 and December 31, 2017, the Company had restricted cash of $25,000 and $370,000, respectively.

Accounts Receivable

Accounts receivable are reported net of the allowance for doubtful accounts.  The allowance for doubtful accounts is determined based on a review of the Company’s receivables.  Receivable accounts are charged off when collection efforts have failed or the account is deemed uncollectible.  During 2016, the Company determined that a receivable account from a third-party natural gas and NGLs purchaser would no longer be collectible as a result of the third-party purchaser filing for bankruptcy.  A summary of the activity related to the allowance for doubtful accounts is as follows:

	September 30, 2018		December 31, 2017
	(in thousands)
Allowance for doubtful accounts, beginning of period	$	1,953	$	1,953
Expense		—		—
Reductions/write-offs		—		—
Allowance for doubtful accounts, end of period	$	1,953	$	1,953

Recent Accounting Developments

Leases.  In February 2016, the FASB issued updated guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and enhance disclosures regarding key information about leasing arrangements.  Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Additionally, in January 2018, the FASB issued an amendment to the updated guidance to permit an entity to elect an optional transition practical expedient to not evaluate under the new guidance land easements that exist or expire before the adoption of the updated guidance and that were not previously accounted for as leases under previous guidance.  In July 2018, the FASB issued an additional amendment that permits an entity to elect an additional transition method to the existing modified retrospective transition requirements.  Under the new transition method, an entity could adopt the provisions of this update by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption.  Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard may continue to be in accordance with the previous lease guidance.  This amendment also allows a practical expedient that permits lessors to not separate non-lease components from the associated lease component if certain conditions are present. The amendments in this update are effective beginning on January 1, 2019 and should be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements.  Early adoption is permitted.  The Company has commenced analyzing its lease contracts but has not yet determined what the effects of adopting this updated guidance will be on its consolidated financial statements.  The Company will adopt this updated guidance in the first quarter 2019 and anticipates that it will recognize a right of use asset and lease liability on the adoption date. The Company plans to apply practical expedients provided in the standards update that allow, among other things, not to reassess contracts that commenced prior to the adoption. The Company also anticipates electing a policy not to recognize right of use assets and lease liabilities related to short-term and immaterial leases.

Revenue Recognition.  On January 1, 2018, the Company adopted Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“ASC 606”) using the modified retrospective method of transition.  Under the modified retrospective approach, the standard has been applied to all existing contracts as of the date of initial application with the cumulative effect of applying the standard, if any, recognized in retained earnings.  

The impact of adoption on our current period results is as follows:

	Three Months Ended September 30, 2018							Nine Months Ended September 30, 2018
	Under ASC 606		Under ASC 605		Increase (Decrease)			Under ASC 606		Under ASC 605		Increase (Decrease)
	(in thousands)							(in thousands)
Revenues:
Oil and condensate	$	17,436	$	17,448	$	(12	)	$	54,497	$	54,530	$	(33	)
Natural gas		1,986		2,752		(766	)		5,618		7,708		(2,090	)
NGLs		2,092		2,593		(501	)		7,315		8,629		(1,314	)
Total oil and condensate, natural gas and NGLs revenues	$	21,514	$	22,793	$	(1,279	)	$	67,430	$	70,867	$	(3,437	)
Expenses:
Transportation, treating and gathering	$	—	$	1,279	$	(1,279	)	$	—	$	3,437	$	(3,437	)
Net income (loss)	$	21,514	$	21,514	$	—		$	67,430	$	67,430	$	—
Retained earnings	$	21,514	$	21,514	$	—		$	67,430	$	67,430	$	—

The primary impact to our revenues as a result of the adoption of ASC 606 is the recording of transportation, treating, gathering and compression expenses (“Post-Production Expenses”) as a direct reduction to revenues instead of our historical practice of presenting such expenses gross in transportation, treating and gathering.  These changes are due to the conclusion that the Company represents the agent in the sale of natural gas and NGLs under its gas processing and marketing agreements with midstream entities in accordance with the control model in ASC 606.  As a result, the Company is required to record revenue on a net basis for amounts expected to be received from third-party customers through the marketing process, with Post-Production Expenses incurred subsequent to control of the product(s) transferring to the midstream entity at the wellhead being netted against revenue.

4. Property, Plant and Equipment

The amount capitalized as oil and natural gas properties was incurred for the purchase and development of various properties in the U.S., specifically in the State of Oklahoma.  

The following table summarizes the components of unproved properties excluded from amortization at the dates indicated:

	September 30, 2018		December 31, 2017
	(in thousands)
Unproved properties, excluded from amortization:
Drilling in progress costs	$	800	$	4,772
Acreage acquisition costs		122,455		113,191
Capitalized interest		21,131		13,992
Total unproved properties excluded from amortization	$	144,386	$	131,955

The full cost method of accounting for oil and natural gas properties requires a quarterly calculation of a limitation on capitalized costs, often referred to as a full cost ceiling calculation. The ceiling is the present value (discounted at 10% per annum) of estimated future cash flow from proved oil, condensate, natural gas and NGLs reserves reduced by future operating expenses, development expenditures, abandonment costs (net of salvage) to the extent not included in oil and natural gas properties pursuant to authoritative guidance and estimated future income taxes thereon. To the extent that the Company's capitalized costs (net of accumulated depletion and deferred taxes) exceed the ceiling at the end of each reporting period, the excess must be written off to expense for such period. Once incurred, this impairment of oil and natural gas properties is not reversible at a later date even if oil and natural gas prices increase. The ceiling calculation is determined using a mandatory trailing 12-month unweighted arithmetic average of the first-day-of-the-month commodities pricing and costs in effect at the end of the period, each of which are held constant indefinitely (absent specific contracts with respect to future prices and costs) with respect to valuing future net cash flows from proved reserves for this purpose.  The 12-month unweighted arithmetic average of the first-day-of-the-month commodities prices are adjusted for basis and quality differentials in determining the present value of the proved reserves.  The table below sets forth relevant pricing assumptions utilized in the quarterly ceiling test computations for the respective periods noted before adjustment for basis and quality differentials:

	2018
	Total Year to Date Impairment		September 30		June 30		March 31
Henry Hub natural gas price (per MMBtu)(1)			$	2.91	$	2.92	$	3.00
WTI oil price (per Bbl)(1)			$	63.43	$	57.67	$	53.49
Impairment recorded (pre-tax) (in thousands)	$	17,993	$	—	$	17,993	$	—

	2017
	Total Year to Date Impairment		September 30		June 30		March 31
Henry Hub natural gas price (per MMBtu)(1)			$	3.00	$	3.01	$	2.73
WTI oil price (per Bbl)(1)			$	49.81	$	48.95	$	47.61
Impairment recorded (pre-tax) (in thousands)	$	—	$	—	$	—	$	—

(1) For the respective periods, oil and natural gas prices are calculated using the trailing 12-month unweighted arithmetic average of the first-day-of-the-month prices based on Henry Hub spot natural gas prices and WTI spot oil prices.

The Company could potentially incur additional ceiling test impairments in the future should commodities prices decline or the value of its estimates of proved reserves declines. However, it is difficult to project future impairment charges in light of numerous variables involved.

The Company’s proved reserves estimates and their estimated discounted value and standardized measure will also be impacted by changes in lease operating costs, future development costs, production, exploration and development activities and estimated future income taxes.  The ceiling limitation calculation is not intended to be indicative of the fair market value of the Company’s proved reserves or future results.

The Company’s undeveloped reserves previously classified as proved, other than the PUD reserves associated with certain wells developed prior to June 30, 2018 or in the process of drilling and completion at June 30, 2018, were reclassified as unproved at June 30, 2018 due to the inability to meet the reasonable certainty criteria for proved reserves, as prescribed under the SEC rules, primarily due to the uncertainties regarding the availability and timing of funds required to develop these reserves.  As of September 30, 2018, the Company has no PUD reserves since all prior PUD reserves recognized at June 30, 2018 have been converted to proved developed.  

WEHLU Sale

On January 23, 2018, the Company entered into a definitive agreement of sale and purchase (the “Sale Agreement”) to divest its interest in the West Edmund Hunton Lime Unit (“WEHLU”) and adjacent undeveloped acreage to Revolution Resources, LLC, for $107.5 million, subject to, among other customary adjustments, adjustments for a property sale effective date of October 1, 2017 (the “WEHLU Sale”).  Pursuant to the Sale Agreement, the WEHLU Sale closed on February 28, 2018.  After effective date and other adjustments of approximately $9.9 million primarily related to revenues and direct operating expenses, net cash proceeds from the WEHLU Sale were approximately $97.6 million.  The WEHLU Sale was reflected as a reduction to the full cost pool and no gain or loss was recorded related to the divestiture as such divestiture did not result in a significant change to the depletion rate.

The following unaudited pro forma results for the three months ended September 30, 2017 and the nine months ended September 30, 2018 and 2017 show the effect on the Company's consolidated results of operations as if the WEHLU Sale had occurred at the beginning of the periods presented.  The pro forma results are the result of excluding from the statement of operations of the Company the revenues and direct operating expenses for the properties divested adjusted for (1) the reduction in asset retirement obligation liabilities and accretion expense for the properties divested and (2) the reduction in depreciation, depletion and amortization expense as a result of the divestiture.  As a result, certain estimates and judgments were made in preparing the pro forma adjustments.

STACK Leasehold Acquisition

On March 22, 2017, the Company completed the acquisition of additional working and net revenue interests in approximately 66 gross (9.5 net) producing wells and 5,670 net acres of additional undeveloped STACK Play leasehold in Kingfisher County, Oklahoma, effective March 1, 2017, for $51.4 million (the “STACK Leasehold Acquisition”).  Prior to the completion of the STACK Leasehold Acquisition, the Company held an interest in the majority of acquired producing wells and acreage.  The Company accounted for the STACK Leasehold Acquisition as an asset acquisition.  

Development Agreement

On October 14, 2016, the Company executed an agreement with STACK Exploration LLC (the “Investor”) (the “Development Agreement”) to jointly develop up to 60 Gastar operated wells in the STACK Play in Kingfisher County, Oklahoma (the “Drilling Program”).  The Drilling Program targeted the Meramec and Osage formations within the Mississippi Lime in a contract area within three townships covering approximately 32,900 gross (21,200 net) undeveloped mineral acres under leases held by the Company. The Company serves as the operator of all Drilling Program wells.      

Under the Development Agreement, the Investor funded 90% of the Company’s working interest portion of drilling and completion costs to initially earn 80% of the Company’s working interest in each new well (in each case, proportionately reduced by other participating working interests in the well).  As a result, the Company paid 10% of its working interest portion of such costs for 20% of its original working interest.  

The proposed Drilling Program wells were to be mutually developed in three tranches of 20 wells each.  The locations of the first 20 wells, comprised of 18 Meramec formation wells and two Osage formation wells, were mutually agreed upon by the Company and the Investor.   Participation in the second tranche of 20 Drilling Program wells was to be at the election of the Investor and the third tranche of 20 wells would require mutual consent.  On July 31, 2017, the Investor elected not to participate in the second tranche of wells.  With respect to each 20-well tranche, when the Investor has achieved an aggregate 15% internal rate of return for its investment in the tranche, Investor’s interest will be reduced from 80% to 40% of the Company’s original working interest and the Company’s working interest increases from 20% to 60% of the original working interest.  When a tranche internal rate of return of 20% is achieved by the Investor, Investor’s working interest decreases to 10% and the Company’s working interest increases to 90% of the working interest originally owned by the Company. 

If and when the final reversion of working interest in the completed 20 well tranche should occur, the Investor has the right, but not the obligation, for a period of six months to cause the Company to purchase the Investor’s remaining interest in the 20 wells in the Drilling Program (the “WI Tail”) for such tranche (the “Investor Put Right”) for fair market value by applying the methodology to determine a 15% discounted present value as defined by the Development Agreement.  If the Investor fails to exercise the Investor Put Right within the six-month period after achieving final reversion, then for a period of six months thereafter, the Company shall have the right, but not the obligation, to purchase the WI Tail from the Investor on the same fair market value approach of the Investor Put Right.  If final reversion has not been achieved by August 19, 2024, Investor will, for a period of six months thereafter, have the right to cause the Company to buy Investor’s then-current interest in the Drilling Program wells at an agreed upon valuation.  Based on current commodity prices, well cost and production performance of the completed wells drilled in the first tranche, the 15% of internal rate of return is not anticipated to be achieved.  

By December 31, 2017, the Company and the Investor had completed all 20 gross (15.8 net; 3.2 net to the Company) wells within the first tranche of the Drilling Program.

Ares Investment Transactions

On March 3, 2017, certain funds (the “Purchasers”) managed indirectly by Ares purchased from the Company for cash (i) $125.0 million aggregate principal amount of its Notes sold at par, which Notes, subject to the receipt of approval of the Company’s stockholders which was obtained on May 2, 2017, are convertible into common stock or, in certain circumstances, cash in lieu of common stock or a combination of cash and shares of common stock as described below and (ii) 29,408,305 shares of common stock for a purchase price of $50.0 million at a purchase price of $1.7002 per share based on a 30-trading day volume weighted average price (“VWAP”) determined on February 15, 2017.  In addition, an affiliate of Ares concurrently loaned the Company $250.0 million pursuant to the Term Loan, as borrower, the guarantors party thereto, AF V Energy I Holdings, L.P., a fund managed indirectly by Ares Management LLC, as lender, and Wilmington Trust, National Association, as Administrative Agent as further described below.  The proceeds from the sale of the Notes, the common stock and the Term Loan were used to fully repay and redeem the Company’s prior Revolving Credit Facility (as defined below) and to satisfy and discharge its $325.0 million of 8.625% senior secured notes due May 2018, which were satisfied and discharged on March 3, 2017 by irrevocably calling for redemption and depositing with the indenture trustee cash in the amount of the redemption price of 102.156% of their principal amount plus accrued and unpaid interest to the redemption date of March 24, 2017, and to pay the expenses from the Ares transactions.  

In order to provide funding for the STACK Leasehold Acquisition and a portion of the Company’s 2017 capital budget, on March 21, 2017, the Purchasers purchased from the Company for cash an additional $75.0 million aggregate principal amount of its Notes sold at par (the “Additional Notes”).  

The Notes, including the Additional Notes, were issued with conversion rights that were subject to the approval of holders of issued and outstanding common stock (other than the Purchasers), which approval was obtained May 2, 2017 (the “Requisite Stockholder Approval”).  Pursuant to the purchase agreement for the Additional Notes, upon receipt of Requisite Stockholder Approval, Purchasers and the Company exchanged $37.5 million principal amount of the Additional Notes for (a) 25,456,521 newly issued shares of common stock (the “Repurchase Shares”) and (b) 2,000 shares of the Company’s Special Voting Preferred Stock, par value $0.01 per share (the “Mandatory Repurchase”).  The terms of Mandatory Repurchase, which was effected May 5, 2017, provided for one Repurchase Share issued for each $1.4731 of outstanding principal of the repurchased Notes, which was based on the 10-day VWAP of the common stock for the period ended March 17, 2017.  The exchange reduced the aggregate principal amount of issued and outstanding Notes from $200.0 million to $162.5 million at June 30, 2017, which principal amount remained outstanding at September 30, 2018.

Term Loan

On March 3, 2017, the Company entered into a credit agreement for the Term Loan. The Term Loan bears interest at a per annum rate equal to 8.5%, payable on a quarterly basis on each March 31, June 30, September 30 and December 31 of each year, commencing March 31, 2017.  The Term Loan has a scheduled maturity of March 3, 2022.  In addition, prepayment of the Term Loan is subject to an interest “make-whole” and prepayment premium, such that any prepayment of the loans thereunder prior to the stated maturity date shall be subject to the payment of a prepayment premium, and depending on the date of such prepayment, the applicable interest “make-whole” amount, with the amount of such prepayment premium decreasing over the life of the Term Loan.  

The Term Loan is guaranteed by the Company’s sole domestic subsidiary and will be guaranteed by all of the Company's future domestic subsidiaries formed during the term of the Term Loan. The Term Loan is secured by a first-priority lien on substantially all of the assets of the Company and its subsidiaries, excluding certain assets as customary exceptions.

The Term Loan contains various customary covenants for credit facilities of this type, including, among others, restrictions on granting liens, incurrence of other indebtedness, payments of certain dividends and other restricted payments, engaging in transactions with affiliates, dispositions of assets and other, in each case subject to certain baskets and exceptions.    

All outstanding amounts owed become due and payable upon the occurrence of certain usual and customary events of default, including among others (i) failure to make payments; (ii) non-performance of covenants and obligations continuing beyond any applicable grace period; and (iii) the occurrence of a change in control of the Company, as defined in the Term Loan.  As of September 30, 2018, no events of default had occurred.

The Company’s voluntary filing of its petition in the Chapter 11 Cases on October 31, 2018 constituted an event of default that accelerated the Company’s obligations under the Term Loan.  Under the Bankruptcy Code, the creditors under the Term Loan and other debt agreements are stayed from taking any action against the Company as a result of an event of default.  See Note 2 – Going Concern for additional information about the Chapter 11 Cases and the proposed Plan.

The Company accounted for the Term Loan in accordance with guidance relating to “Debt with Conversion and Other Options” which indicates that when multiple securities are issued in a single transaction, total proceeds should be allocated based on the relative fair values of each instrument, assuming no instrument is subsequently required to be recorded at fair value.  The fair value of the Term Loan at the date of issuance was determined to be at a discounted $224.8 million based on the fair value of similar debt instruments.  The $25.2 million debt discount related to the Term Loan was initially recorded as a reduction to the Term Loan liability and as additional paid-in capital on the Company’s consolidated balance sheet.  The $5.5 million of issuance costs associated with the Term Loan are recorded as a reduction to the Term Loan liability.  Both the debt discount and issuance costs will be amortized over the life of the Term Loan using the effective interest method.  The effective interest rate for the Term Loan is approximately 13.0% per annum.

On March 20, 2017, the Company, together with the parties thereto, entered into Amendment No. 1 to the Term Loan credit agreement which amendment permitted the issuance of the Additional Notes.  

On August 2, 2017, the Company, together with the parties thereto, entered into an Amendment No. 2 to Term Loan credit agreement (“Amendment No. 2”).  Amendment No. 2 amended the Term Loan, to among other things, (i) allow for the payment of pay in kind (“PIK”) interest on the Term Loan at the applicable PIK percentage and (ii) increased the applicable interest rate for periods ending after June 30, 2017 from 8.5% per annum to 10.25% per annum.  Amendment No. 2 allows the Company to elect to PIK upon proper notice 100% of interest payments due after June 30, 2017 and prior to December 31, 2018 and at the Company’s election, PIK between 0% and 50% of any interest payments occurring after December 31, 2018 (other than interest due on the maturity date or the date of any repayment or prepayment).  The Term Loan interest rate increased from 8.5% per annum to 10.25% per annum for all interest periods post June 30, 2017 and the PIK interest shall be payable by capitalizing and adding such amounts to the outstanding principal amount of the Term Loan on the applicable interest payment date.

On September 18, 2017, the Company, together with the parties thereto, entered into Amendment No. 3 to the Term Loan credit agreement (“Amendment No. 3”).  Amendment No. 3 amended the Term Loan to, among other things, expressly provide that certain assignments of oil and natural gas properties made or to be made by the Company to Red Bluff Resources Operating, LLC (“Red Bluff”), pursuant to the Red Bluff Purchase and Sale Agreement dated October 19, 2016 between the Company and Red Bluff (“Red Bluff PSA”), are permitted by the Term Loan and are not subject to the mandatory prepayment provisions applicable to “Asset Sales” under the Term Loan.

On June 29, 2018, the Company, together with the parties thereto, entered into Amendment No. 4 to the Term Loan credit agreement (“Amendment No. 4”).  Amendment No. 4, among other things, (i) reduced the period the Company could cure a default resulting from the failure to comply with certain covenants applicable to the Term Loan from 30 days to 15 days, (ii) waived certain defaults under the Term Loan and (iii) prohibited the Company from making cash dividends or distributions on or with respect to its capital stock, other than cash dividends on its Series A Preferred Stock and Series B Preferred Stock declared for the month of June 2018.              

The carrying amounts of the Term Loan for the periods indicated are as follows:

	September 30, 2018			December 31, 2017
	(in thousands)
Term Loan, principal balance(1)	$	276,778		$	256,599
Less:

Unamortized debt discount		(19,873	)		(22,464	)
Term loan, net	$	252,903		$	229,411

(1) Pursuant to Amendment No. 2, the Company can elect to pay in kind 100% of the interest due after June 30, 2017 to December 31, 2018.  The Company elected to pay in kind 100% of the interest due for the period June 30, 2017 to July 2, 2018 in the amount of $26.8 million, thus increasing the outstanding principal balance of the Term Loan to $276.8 million.  The Company elected to pay in kind 100% of the interest due for the period July 2, 2018 to September 30, 2018 in the amount of $7.0 million and such was accrued at September 30, 2018 due to the interest payment date falling on a weekend outside of quarter end.  

Indenture and Notes

The principal terms of the Notes are governed by the Indenture. Pursuant to the Indenture, the Notes were issued for cash at par, bear interest at 6.0% per annum and will mature on March 1, 2022, unless earlier repurchased, redeemed or converted in accordance with the terms of the Indenture. Interest is payable on the Notes on each March 1, June 1, September 1 and December 1 of each year, commencing on June 1, 2017.  

Pursuant to the Indenture, Requisite Stockholder Approval was required on or before July 3, 2017 to approve the conversion rights of the Notes (including the Additional Notes) to be convertible at the option of the holder into shares of common stock based on the terms of the Indenture.  Requisite Stockholder Approval was obtained on May 2, 2017 at a special meeting of stockholders.  

The interest rate on the Notes was subject to an increase in certain circumstances if the Company fails to comply with certain obligations under a Registration Rights Agreement and on the Notes in the case of certain issuances of common stock by the Company at a price below $1.7002 per share (subject to adjustment).

The Notes are secured by a second-priority lien on substantially all of the assets of the Company and its sole subsidiary. If at least a majority of the Notes issued pursuant to the Securities Purchase Agreement dated February 16, 2017 (the “Purchase Agreement”) cease to be held by affiliates of Ares as provided in the Indenture, the liens securing the Notes will be released and substantially all of the restrictive covenants in the Indenture will terminate.  

The Indenture restricts the ability of the Company and certain of its subsidiaries to, among other things: (i) pay dividends or make other distributions in respect of the Company’s capital stock or make other restricted payments; (ii) incur additional indebtedness and issue preferred stock; (iii) make certain dispositions and transfers of assets; (iv) engage in transactions with affiliates; (v) create liens; (vi) engage in certain business activities that are not related to oil and gas; and (vii) impair any security interest. These covenants are subject to a number of exceptions and qualifications. 

The Indenture provides that a number of events will constitute an Event of Default (as defined in the Indenture), including, among other things: (i) a failure to pay the Notes when due at maturity, upon redemption or repurchase; (ii) failure to pay interest for 30 days; (iii) the Company’s failure to deliver certain notices; (iv) a default in the Company’s obligation to convert the Notes; (v) the Company’s failure to comply with certain covenants relating to merger, consolidation or sale of assets; (vi) the Company’s failure to comply, for 60 days following notice, with any of the other covenants or agreements in the Indenture; (vii) a default, which is not cured within 30 days, by the Company or any Restricted Subsidiaries (as defined in the Indenture) with respect to any mortgages or any indebtedness for money borrowed of at least $15 million; (viii) one or more final judgments against the Company or any of its Restricted Subsidiaries for the payment of at least $15 million; (ix) the Company’s failure to make any payments required under that certain development agreement, which is not cured within 30 days; (x) causing any Guarantee (as defined in the Indenture) to cease to be in full force and effect; (xi) the cessation to be in full force and effect of any of the collateral agreements entered into with respect to the Notes; and (xii) certain events of bankruptcy or insolvency. In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.  At September 30, 2018, no Event of Default had occurred.      

The Company’s voluntary filing of its petition in the Chapter 11 Cases on October 31, 2018 constituted an event of default that accelerated the Company’s obligations under the Notes.  Under the Bankruptcy Code, the creditors under the Notes and other debt agreements are stayed from taking any action against the Company as a result of an event of default.  See Note 2 – Going Concern for additional information about the Chapter 11 Cases and the proposed Plan.

On June 29, 2018, the Company, the subsidiary guarantor named therein and the Trustee, entered into a Second Supplemental Indenture (the “Second Supplemental Indenture”), which supplements the Indenture.  The Second Supplemental Indenture, among other things, (i) waived certain defaults, (ii) reduced the period the Company could cure certain covenant defaults under the Indenture from 60 days to 15 days and (iii) prohibited the Company and its subsidiary from making cash dividends or distributions on or with respect to its capital stock, other than cash dividends on its Series A Preferred Stock and its Series B Preferred Stock declared for the month of June 2018.

In accordance with accounting guidance relating to “Debt with Conversion and Other Options” which indicates that when multiple securities are issued in a single transaction, total proceeds should be allocated based on the relative fair values of each instrument, assuming no instrument is subsequently required to be recorded at fair value.  The Company accounted for the Notes based on their relative fair value to the bundled transaction and subsequently separately accounted for the liability and equity conversion components of the Notes due to the Company’s option to settle the conversion obligation in cash.  The fair value of the debt portion of the Notes, excluding the conversion feature, at the dates of issuance was estimated to be approximately $147.8 million and was calculated based on the fair value of similar non-convertible debt instruments in conjunction with the relative fair value of the Term Loan issued on the same date.  As a result of such valuation, a debt discount of $52.4 million related to the Notes was recorded.  Additionally, the value of the conversion option at the dates of issuance was calculated to be $77.6 million based on the residual fair value after application of such to the debt and was recorded as additional paid-in capital on the Company’s condensed consolidated balance sheet.  Total debt issuance costs related to the Notes were $5.4 million, of which $3.2 million was allocated to the liability component of the Notes and $2.2 million to the equity component of the Notes.  The debt discount and the liability component of the debt issuance costs will be amortized over the term of the Notes.  The weighted average effective interest rate used to amortize the debt discount and the liability component of the debt issue costs for the Notes is approximately 16% based on the Company’s estimated non-convertible borrowing rate as of the date the Notes were initially issued.  

The carrying amount of the liability component of the Notes for the periods indicated are as follows:

Second Amended and Restated Revolving Credit Facility

On June 7, 2013, the Company entered into the Second Amended and Restated Credit Agreement among the Company, Wells Fargo Bank, National Association, as Administrative Agent, Collateral Agent, Swing Line Lender and Issuing Lender and the lenders named therein (the “Revolving Credit Facility”).   The Revolving Credit Facility had a scheduled maturity of November 14, 2017.

On January 10, 2017, the Company, together with the parties thereto, entered into an amendment to the Second Amended and Restated Credit Agreement (“Amendment No. 10”), which amended the Revolving Credit Facility to, among other things, permit the payment of certain cash dividends on its preferred stock, including the dividends declared payable on January 31, 2017, provided that (i) the Company’s borrowing base was correspondingly reduced in the amount of any such dividend payment and (ii) the Company paid down its outstanding indebtedness under the Revolving Credit Facility in the amount of any resulting borrowing base deficiency.

Under Amendment No. 10, payment of the declared January 2017 dividend and monthly preferred stock cash dividends through May 2017 was permitted contingent upon the satisfaction of certain conditions, including but not limited to, (i) the absence of any defaults or borrowing base deficiency, (ii) for any dividends declared and paid in respect of April 2017 and May 2017, having cash liquidity (including any available borrowings under the Revolving Credit Facility) of more than $30.0 million and (iii) paying any permitted dividends solely from proceeds received by the Company from sales of equity since November 30, 2016 (including through the Company’s at-the-market issuance sales agreement with a third-party sales agent to sell, from time to time, shares of the Company’s common stock (the “ATM Program”).  Under Amendment No. 10, the Company also agreed to pay down indebtedness under its Revolving Credit Facility by at least an additional $8.1 million by April 30, 2017.  

On March 3, 2017, the Company used a portion of the net proceeds from the transactions described in this Note 5 under the caption “Ares Investment Transactions” above to fully repay all of the $69.2 million borrowings outstanding under the Revolving Credit Facility (which was terminated on such date).

Senior Secured Notes

At December 31, 2016, the Company had $325.0 million aggregate principal amount of 8 5/8% Senior Secured Notes due May 15, 2018 (the “Former Notes”) outstanding under an indenture by and among the Company, the Guarantors named therein (the “Guarantors”), Wells Fargo Bank, National Association, as Trustee (in such capacity, the “Former Notes Trustee”) and Collateral Agent.  The Former Notes bore interest at a rate of 8.625% per year, payable semi-annually in arrears on May 15 and November 15 of each year.  

On March 3, 2017, the redemption price plus interest on all of the Company’s outstanding $325.0 million principal of the Former Notes was funded to satisfy and discharge the Former Notes from a portion of the net proceeds from the transactions described in this Note 5 under the caption “Ares Investment Transactions” above.  All of the Former Notes were satisfied and discharged on March 3, 2017 by irrevocably calling for redemption and depositing with the indenture trustee cash in the amount of the redemption price of 102.156% of  the principal amount, or principal plus an additional $7.0 million, plus accrued and unpaid interest to the redemption date of March 24, 2017.  Additionally, the Company wrote-off $5.2 million of remaining unamortized deferred financing costs related to the Former Notes upon redemption.

Fair Value Disclosures [Abstract]

Fair Value Measurements

6. Fair Value Measurements

The Company’s financial assets and liabilities are measured at fair value on a recurring basis. The Company discloses its recognized non-financial assets and liabilities, such as asset retirement obligations, unproved properties and other property and equipment, at fair value on a non-recurring basis. For non-financial assets and liabilities, the Company is required to disclose information that enables users of its financial statements to assess the inputs used to develop these measurements. The Company assesses its unproved properties for impairment whenever events or circumstances indicate the carrying value of those properties may not be recoverable.  The fair value of the unproved properties is measured using an income approach based upon internal estimates of future production levels, current and future prices, drilling and operating costs, discount rates, current drilling plans and favorable and unfavorable drilling activity on the properties being evaluated and/or adjacent properties, which are Level 3 (as defined below) inputs.  Should an impairment of unproved properties occur, the value of the impaired properties would be reclassified into proved properties in the full cost pool subject to depletion.  As no other fair value measurements are required to be recognized on a non-recurring basis at September 30, 2018, no additional disclosures are provided.

As defined in the guidance, fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). To estimate fair value, the Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. The Company’s cash equivalents consist of short-term, highly liquid investments, which have maturities of 90 days or less, including sweep investments and money market funds.

• Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

• Level 3 inputs are measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources. These inputs may be used with internally developed methodologies or third party broker quotes that result in management’s best estimate of fair value. The Company’s valuation models consider various inputs including (a) quoted forward prices for commodities, (b) time value, (c) volatility factors and (d) current market and contractual prices for the underlying instruments. Significant increases or decreases in any of these inputs in isolation would result in a significantly higher or lower fair value measurement.  Level 3 instruments are commodity costless collars, index swaps, basis and fixed price swaps and put and call options to hedge oil, natural gas and NGLs price risk. At each balance sheet date, the Company performs an analysis of all applicable instruments and includes in Level 3 all of those whose fair value is based on significant unobservable inputs.  The fair values derived from counterparties and third-party brokers are verified by the Company using publicly available values for relevant NYMEX futures contracts and exchange traded contracts for each derivative settlement location. Although such counterparty and third-party broker quotes are used to assess the fair value of its commodity derivative instruments, the Company does not have access to the specific assumptions used in its counterparties valuation models. Consequently, additional disclosures regarding significant Level 3 unobservable inputs were not provided and the Company does not currently have sufficient corroborating market evidence to support classifying these contracts as Level 2 instruments.

As required, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values below incorporates various factors, including the impact of the counterparty’s non-performance risk with respect to the Company’s financial assets and the Company’s non-performance risk with respect to the Company’s financial liabilities. The Company has not elected to offset the fair value amounts recognized for multiple derivative instruments executed with the same counterparty, but reports them gross on its consolidated balance sheets.

Transfers between levels are recognized at the end of the reporting period. There were no transfers between levels during the 2018 and 2017 periods.

The following tables set forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2018 and December 31, 2017:

At September 30, 2018, the estimated fair value of accounts receivable and accounts and revenue payables approximates their carrying value due to their short-term nature. The estimated fair value of the Notes excluding the conversion feature at September 30, 2018 was $113.1 million calculated based on the fair value of similar non-convertible debt instruments (Level 2) since an observable quoted price of the Notes or a similar asset or liability is not readily available.  The estimated fair value of the Term Loan at September 30, 2018 was $241.0 million calculated based on the fair value of similar debt instruments (Level 2) since an observable price of the Term Loan or a similar asset or liability is not readily available.

Total revenues from contracts with customers	$	21,514	$	18,228	$	67,430	$	52,865

(1) Prior period amounts have not been adjusted under the modified retrospective method.

Revenue Recognition

Oil, condensate, natural gas and NGLs revenues are recognized at the point in time that control of the product is transferred to the customer and collectability is reasonably assured.  A more detailed summary of the underlying contracts that give rise to revenue and method of recognition are included below.

Oil and Condensate Sales

Under the Company’s oil and condensate sales contracts, the Company delivers all or a specified percentage of the crude oil production from specified leases to the nominated delivery point which is the outlet flange of the Company’s lease facility or at unit storage tanks.  The Company sells oil and condensate production at the delivery point and collects an agreed-upon index price, net of applicable transport differential.  The Company recognizes revenue when control transfers to the purchaser at the delivery point at the net price received.

Natural Gas and NGLs Sales

Under the Company’s gas processing contracts, the Company delivers all or a specified percentage of natural gas production to a midstream processing entity at the wellhead or the inlet of the midstream processing entity’s system.  The midstream processing entity processes the natural gas, sells the resulting NGLs and residue gas to third parties and pays the Company for the NGLs and residue gas with deductions for Post-Production Expenses.  The NGLs are subject to an incremental NGLs pricing formula based upon a percentage of NGLs extracted from the Company’s wet gas.  For the Company’s gas processing contracts, the Company evaluates whether it is the principal or the agent.  For the Company’s existing contracts, it has concluded that it is the agent and the midstream processing entity is the Company’s customer, and therefore, the Company recognizes revenue when control transfers to the midstream processing entity for the net amount of the proceeds received.  If for future contracts the Company was to conclude that it is the principal with the ultimate third party being the customer, the Company would recognize revenue for those contracts on a gross basis, with Post-Production Expenses presented gross as expenses.

Imbalances

The Company recognizes revenue for all oil, condensate, natural gas and NGLs sold to purchasers regardless of whether the sales are proportionate to the Company’s ownership interest in the property.  Production imbalances are recognized as a liability to the extent an imbalance on a specific property exceeds the Company’s share of remaining proved oil and natural gas reserves.  The Company had no material imbalances at September 30, 2018 or 2017.

Significant Judgments

Principal versus Agent

The Company engages in various types of transactions in which midstream entities process its wet gas and, in some scenarios, subsequently market resulting NGLs and residue gas to third-party customers on the Company’s behalf, such as gas processing contracts.  These types of transactions require judgment to determine whether the Company is the principal or the agent in the contract and, as a result, whether revenues are recorded gross or net.  For the Company’s existing contracts, the Company has determined that it represents the agent in the sale of products under certain gas processing and marketing agreements with midstream entities in accordance with the control model in ASC 606.  As a result, the Company presents revenue on a net basis for amounts expected to be received from third-party customers through the marketing process, with Post-Production Expenses incurred subsequent to control of the product(s) transferring to the midstream entity being netted against revenue.  

Transaction Price Allocated to Remaining Performance Obligations

A significant number of the Company’s product sales are short-term in nature with a contract term of one year or less.  For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14 that exempts it from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

For the Company’s product sales that have a contract term greater than one year, the Company has utilized the practical expedient in ASC 606-10-50-14A that states that it is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation.  Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Contract Balances

Under the Company’s customer contracts, the Company receives a remittance advice confirming purchased volumes and pricing from its customers once the Company’s performance obligations have been satisfied, at which point payment is unconditional.  Accordingly, the Company’s contracts do not give rise to contract assets or liabilities under ASC 606.  All of the Company’s revenue accounts receivable balances are attributable to revenues from contracts with customers.  

Prior-period Performance Obligations

The Company records revenue in the month its production is delivered to the purchaser.  However, settlement statements and payment may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production that was delivered to the purchaser and the price that will be received for the sale of the product including any transportation and other deductions.  The Company uses its knowledge of its properties, historical performance, contractual data, the anticipated effect of weather conditions during the month of production and prevailing market as the basis for these estimates.  The Company records the variances between its estimates and the actual amounts received in the month payment is received and such variances have historically not been material.  For the three and nine months ended September 30, 2018, revenue recognized in the reporting period related to performance obligations satisfied in prior reporting periods was not material.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activity

8. Derivative Instruments and Hedging Activity

The Company maintains a commodity price risk management strategy that uses derivative instruments to minimize significant, unanticipated earnings fluctuations that may arise from volatility in commodity prices. The Company uses costless collars, index, basis and fixed price swaps and put and call options to hedge oil, condensate, natural gas and NGLs price risk.

All derivative contracts are carried at their fair value on the balance sheet and all changes in value are recorded in the condensed consolidated statements of operations in (loss) gain on commodity derivatives contracts.  For the three months ended September 30, 2018 and 2017, the Company reported a gain of $433,000 and a loss of $4.7 million, respectively, in the condensed consolidated statements of operations related to the change in the fair value of its commodity derivative contracts still held at September 30, 2018 and 2017.  For the nine months ended September 30, 2018 and 2017, the Company reported losses of $9.0 million and $1.9 million, respectively, in the condensed consolidated statements of operations related to the change in the fair value of its commodity derivative contracts still held at September 30, 2018 and 2017.  For the three months ended September 30, 2018 and 2017, the Company reported a loss of $3.4 million and a gain of $1.8 million, respectively, in the condensed consolidated statements of operations for the settlement of derivatives during the respective periods.  For the nine months ended September 30, 2018 and 2017, the Company reported a loss of $8.7 million and a gain of $5.7 million, respectively, in the condensed consolidated statements of operations for the settlement of derivatives during the respective periods.    

As of September 30, 2018, the following crude derivative transactions were outstanding with the associated notional volumes and weighted average underlying hedge prices:

As of September 30, 2018, all of the Company’s economic derivative hedge positions were with large institutions, which are not known to the Company to be in default on their derivative positions.  The Company is exposed to credit risk to the extent of non-performance by the counterparties in the derivative contracts discussed above; however, the Company does not anticipate non-performance by such counterparties. None of the Company’s derivative instruments contain credit-risk related contingent features.

On October 26, 2018, the Company and the Hedge Parties entered into the Hedge Party RSA to effectively terminate the Company’s current hedge positions and replace such with new secured notes to be paid in monthly installments through December 2019 (the “Hedge Party Secured Notes”).  The Hedge Party RSA and term sheet appended thereto provide for the treatment of claims held by Hedge Parties described above.  The Hedge Party RSA contains certain covenants on the part of each of the Company and the Hedge Parties, including commitments by the Hedge Parties to vote in favor of the Plan and commitments of the Company and the Hedge Parties to negotiate in good faith to finalize certain documents and agreements. The Hedge Party RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Hedge Party RSA.  The Hedge Party Secured Notes will be secured by an uncapped first priority security interest in the collateral that secures the Exit Facility which security interest and lien shall rank pari passu with the liens granted to the Company’s senior-most creditors (with respect to debt for borrowed money).  On November 1, 2018, the Company’s current hedge positions were terminated and the value of the Hedge Party Secured Notes was determined to be $12.4 million, subject to approval by the Bankruptcy Court.  The Hedge Party Secured Notes mature on December 31, 2019 during which time no interest shall accrue unless a default occurs under the terms thereof.  Funds in the Exit Facility will be available to make payments under the Hedge Party Secured Notes.

9. Capital Stock

Common Stock

On May 7, 2015, the Company entered into the ATM Program.  The shares were issued pursuant to the Company’s then-existing effective shelf registration statement on Form S-3, as amended (Registration No. 333-193832).  The Company registered shares having an aggregate offering price of up to $50.0 million.  For the period January 1, 2017 to February 20, 2017, the Company sold 5,447,919 shares through the ATM Program for net proceeds of $8.3 million.  The ATM Program expired on February 24, 2017.  

On March 3, 2017, the Purchasers purchased for cash (i) $125.0 million aggregate principal amount of Notes sold at par and (ii) 29,408,305 shares of common stock for a purchase price of $50.0 million before offering costs and expenses.  The common stock sale was priced based on a 30-trading day VWAP of $1.7002 determined on February 15, 2017 the date immediately prior to the signing date of the Purchase Agreement with Purchasers in respect to such sale.  

On March 21, 2017, the Company sold to the Purchasers an additional $75.0 million aggregate principal amount of Notes. Pursuant to the purchase agreement for the Additional Notes, after obtaining the Requisite Stockholder Approval, on May 5, 2017, the Company and the Purchasers exchanged $37.5 million aggregate principal amount of the outstanding Additional Notes for the issuance of 25,456,521 shares of common stock to Purchasers of the Mandatory Repurchase.  

The Notes are convertible into shares of common stock as described in more detail in Note 5.

On June 27, 2017, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to increase the number of authorized shares of common stock from 550,000,000 to 800,000,000, which amendment became effective on July 24, 2017.  At September 30, 2018, there were 218,933,504 shares of the Company’s common stock issued and outstanding.    

Preferred Stock

Pursuant to the Company’s certificate of incorporation, the Company has 40,000,000 shares of preferred stock authorized with a par value of $0.01 per share.  The Company has designated 10,000,000 of such shares to constitute its 8.625% Series A Cumulative Preferred Stock (the “Series A Preferred Stock”) and 10,000,000 of such shares to constitute its 10.75% Series B Cumulative Preferred Stock (the “Series B Preferred Stock”).  The Series A Preferred Stock and the Series B Preferred Stock each have a liquidation preference of $25.00 per share.  On March 22, 2017, the Company designated 2,000 of such shares as Special Voting Preferred Stock with a liquidation preference of $0.01 for each share, which is junior and subordinate to the right of the holders of any shares of any other existing or future series of preferred stock.

Series A Preferred Stock

At September 30, 2018, there were 4,045,000 shares of the Series A Preferred Stock issued and outstanding with a $25.00 per share liquidation preference.

The Series A Preferred Stock ranks senior to the Company's common stock and on parity with the Series B Preferred Stock with respect to the payment of dividends and distribution of assets upon liquidation, dissolution or winding up.  The Series A Preferred Stock is subordinated to all of the Company’s existing and future debt and all future capital stock designated as senior to the Series A Preferred Stock.

The Series A Preferred Stock cannot be converted into common stock, but may be redeemed, at the Company’s option for $25.00 per share plus any accrued and unpaid dividends.

There is no mandatory redemption of the Series A Preferred Stock.

The Company paid monthly dividends on the Series A Preferred Stock at a fixed rate of 8.625% per annum of the $25.00 per share liquidation preference through March 2016.  Effective March 9, 2016, the Revolving Credit Facility prohibited the payment of cash dividends on the Company’s preferred stock commencing April 2016.  Pursuant to Amendment No. 10 to the Company’s Revolving Credit Facility, on January 10, 2017, the Company declared a special cash dividend on the Series A Preferred Stock to pay in full all accumulated and unpaid cash dividends accrued since April 1, 2016 at an annualized 8.625% through the payment date.  The Series A Preferred Stock January 2017 dividend of $7.3 million was paid on January 31, 2017 to holders of record at the close of business on January 20, 2017, which paid all unpaid dividends that accumulated in respect to the Series A Preferred Stock at such time.  Thereafter, all monthly cash dividends on the Series A Preferred Stock were paid for each month through July 2017.  On August 1, 2017, primarily in response to the decline in oil prices and to preserve liquidity, the Company elected to suspend Series A Preferred Stock dividends commencing August 2017, which suspension remained in effect through March 2018.  On April 9, 2018, the Company declared a special cash dividend on the Series A Preferred Stock to pay in full all accumulated and unpaid cash dividends accrued since August 1, 2017 at an annualized 8.625% through the payment date.  The Series A Preferred Stock April 2018 dividend of $6.5 million was paid on April 30, 2018 to holders of record at the close of business on April 20, 2018, which paid all unpaid dividends that accumulated in respect to the Series A Preferred Stock at such time.  The Company continued to declare and pay dividends on the Series A Preferred Stock through June 30, 2018.  On June 11, 2018, the Company elected to suspend the declaration and payment of monthly cash dividends on the Series A Preferred Stock commencing July 2018.  On June 29, 2018, the Company entered into Amendment No. 4 to the Term Loan and into the Second Supplemental Indenture, both of which prohibit the Company from making cash dividends or distributions on or with respect to its capital stock, other than cash dividends on its Series A Preferred Stock and its Series B Preferred Stock declared for the month of June 2018, which were paid on July 2, 2018.          

Dividends on the Series A Preferred Stock accumulate regardless of whether any such dividends are declared.  If the Company has accumulated, accrued and unpaid cash dividends in any calendar month within four calendar quarters, then commencing in the calendar month following the first month in such fourth calendar quarter in which cash dividends are not paid in full, and until accumulated dividends are paid in full for four calendar quarters with the last two calendar quarters’ dividends paid in cash, (i) the fixed dividend rate of Series A Preferred Stock each increases by 2.00% per annum, (ii) the Company will be required to issue a dividend of common stock to pay accrued and unpaid dividends based on then current market value determined in accordance with the certificate of designations applicable to the Series A Preferred Stock, if such dividends are not paid in cash, provided it has sufficient capital surplus to pay such a dividend and can otherwise pay a dividend under state law, and (iii) the holders of Series A Preferred Stock and Series B Preferred Stock,  voting as a single class, will have the right to elect up to two additional directors to the board of directors of the Company.  If the Company’s common stock ceases to be listed on a national securities exchange or a national securities market, “pay in kind” dividends of additional shares of Series A Preferred Stock may be payable in lieu of cash or common stock dividends.  

For the three months ended September 30, 2018, the Company recognized undeclared cumulative dividends on preferred stock of $2.2 million for the Series A Preferred Stock.  For the three months ended September 30, 2017, the Company recognized and paid cash dividends of $727,000 and recognized undeclared cumulative dividends of $1.5 million for the Series A Preferred Stock.  For the nine months ended September 30, 2018, the Company recognized dividends of $4.4 million, recognized undeclared cumulative dividends of $2.2 million and paid cash dividends of $8.0 million, including $3.6 million of 2017 undeclared dividends, for the Series A Preferred Stock.  For the nine months ended September 30, 2017, the Company recognized dividends of $5.1 million, recognized undeclared cumulative dividends of $1.5 million and paid cash dividends of $11.6 million, including $6.5 million of 2016 undeclared dividends, for the Series A Preferred Stock.  As of September 30, 2018, there were $2.2 million of accumulated and unpaid dividends on the outstanding Series A Preferred Stock.        

Series B Preferred Stock

At September 30, 2018, there were 2,140,000 shares of the Series B Preferred Stock issued and outstanding with a $25.00 per share liquidation preference.

The Series B Preferred Stock ranks senior (to the extent of its stated liquidation preference and any accumulated and unpaid dividends) to the Company’s common stock and on parity with Series A Preferred Stock with respect to the payment of dividends and distribution of assets upon liquidation, dissolution or winding up.  The Series B Preferred Stock are subordinated to all of the Company’s existing and future debt and all future capital stock designated as senior to the Series B Preferred Stock.

Except upon a change in ownership or control, the Series B Preferred Stock may not be redeemed before November 15, 2018, at or after which time it may be redeemed at the Company’s option for $25.00 per share in cash. Following a change in ownership or control, the Company will have the option to redeem the Series B Preferred Stock within 90 days of the occurrence of the change in control, in whole but not in part for $25.00 per share in cash, plus accrued and unpaid dividends (whether or not declared), up to, but not including the redemption date. If the Company does not exercise its option to redeem the Series B Preferred Stock upon a change of ownership or control, the holders of the Series B Preferred Stock have the option to convert the shares of Series B Preferred Stock into the Company's common stock based upon on an average common stock trading price then in effect but limited to an aggregate of 11.5207 shares of the Company’s common stock per share of Series B Preferred Stock, subject to certain adjustments. If the Company exercises any of its redemption rights relating to shares of Series B Preferred Stock, the holders of Series B Preferred Stock will not have the conversion right described above with respect to the shares of Series B Preferred Stock called for redemption.

There is no mandatory redemption of the Series B Preferred Stock.

The Company paid monthly dividends on the Series B Preferred Stock at a fixed rate of 10.75% per annum of the $25.00 per share liquidation preference through March 2016. Effective March 9, 2016, the Revolving Credit Facility prohibited the payment of cash dividends on the Company’s preferred stock commencing April 2016.  Pursuant to Amendment No. 10 to the Company’s Revolving Credit Facility, on January 10, 2017, the Company declared a special cash dividend on the Series B Preferred Stock to pay in full all accumulated and unpaid cash dividends since April 1, 2016 at an annualized 10.75% through the payment date.  The Series B Preferred Stock January 2017 dividend in the amount of $4.8 million was paid on January 31, 2017 to holders of record at the close of business on January 20, 2017, which paid all unpaid dividends that accumulated in respect to the Series B Preferred Stock at such time.  Thereafter, all monthly cash dividends on the Series B Preferred Stock were paid for each month through July 2017.  On August 1, 2017, primarily in response to the decline in oil prices and to preserve liquidity, the Company elected to suspend Series B Preferred Stock dividends commencing August 2017, which suspension remained in effect through March 2018.  On April 9, 2018, the Company declared a special cash dividend on the Series B Preferred Stock to pay in full all accumulated and unpaid cash dividends accrued since August 1, 2017 at an annualized 10.75% through the payment date.  The Series B Preferred Stock April 2018 dividend of $4.3 million was paid on April 30, 2018 to holders of record at the close of business on April 20, 2018, which paid all unpaid dividends that accumulated in respect to the Series B Preferred Stock at such time.  The Company continued to declare and pay dividends on the Series B Preferred Stock through June 30, 2018.  On June 11, 2018, the Company elected to suspend the declaration and payment of monthly cash dividends on the Series B Preferred Stock commencing July 2018.  On June 29, 2018, the Company entered into Amendment No. 4 to the Term Loan and into the Second Supplemental Indenture, both of which prohibit the Company from making cash dividends or distributions on or with respect to its capital stock, other than cash dividends on its Series A Preferred Stock and its Series B Preferred Stock declared for the month of June 2018, which were paid on July 2, 2018.

Dividends on the Series B Preferred Stock will accumulate regardless of whether any such dividends are declared. If the Company has accumulated, accrued and unpaid cash dividends in any calendar month within four calendar quarters, then commencing in the calendar month following the first month in such fourth calendar quarter in which cash dividends are not paid in full, and until accumulated dividends are paid in full for four calendar quarters with the last two calendar quarters’ dividends paid in cash, (i) the fixed dividend rate of Series B Preferred Stock each increases by 2.00% per annum, (ii) the Company will be  required to issue a dividend of common stock to pay accrued and unpaid dividends based on then current market value determined in accordance with the certificate of designations applicable to the Series B Preferred Stock, if such dividends are not paid in cash, provided it has sufficient capital surplus to pay such a dividend and can otherwise pay a dividend under state law, and (iii) the holders of Series A Preferred Stock and Series B Preferred Stock,  voting as a single class, will have the right to elect up to two additional directors to the board of directors of the Company.  If the Company’s common stock ceases to be listed on a national securities exchange or a national securities market, “pay in kind” dividends of additional shares of Series B Preferred Stock may be payable in lieu of cash or common stock dividends.

For the three and nine months ended September 30, 2018 and 2017, respectively, the Company did not recognize a current income tax benefit or provision as the Company has a full valuation allowance against assets created by net operating losses generated.  The Company believes it more likely than not that the assets will not be utilized.  The Company had no deferred income tax expense (benefit) for the three and nine months ended September 30, 2018 and 2017.  In connection with the Company’s recent equity and convertible debt transactions during 2017, the Company determined that the utilization of net operating losses in future years is subject to limitations by reason of an “ownership change” as defined under Section 382 of the Internal Revenue Code (“Section 382 Limitation”).  Any utilization of the Company’s net operating loss carryforwards and other tax credit carryforwards will be subject to the Section 382 Limitation.  

The Company is subject to examination of income tax filings in the U.S. and various state jurisdictions for the periods 2010 and forward and the foreign jurisdiction of Canada for the tax periods 2000 through 2013 due to the Company’s continued loss position in such jurisdictions.  The Company is currently under audit by the U.S. Internal Revenue Service for the taxable period ended December 31, 2014.

Litigation

Gastar Exploration Inc. v. Christopher McArthur (Cause No.:  2015-77605) 157th Judicial District Court, Harris County, Texas.  On December 29, 2015, Gastar filed suit against Christopher McArthur (“McArthur”) in the District Court of Harris County, Texas.  The lawsuit arises from a demand letter sent by McArthur to Gastar in which he claimed to be party to an agreement with Gastar that entitled him to be paid $2.75 million for services rendered.  In August 2016, McArthur filed an amended answer admitting he had no agreement with the Company. As a result, Gastar believes McArthur’s claim has been effectively resolved. Gastar has also pursued a claim in this action against McArthur for tortious interference with an existing contract.  On October 17, 2018, the Court entered a judgment in favor of Gastar on this tortious interference claim.  Gastar is currently pursuing collection efforts.  

Torchlight Energy Resources, Inc., Torchlight Energy, Inc. v. Husky Ventures, Inc., et al., (Cause No. 429-01961-2016) 429th Judicial District Court in Collin County, Texas. Torchlight Energy Resources, Inc. and Torchlight Energy, Inc. (collectively “Torchlight”) brought a lawsuit against the Company, two of its executive officers, its chairman of the board of directors and a former director of the Company on May 3, 2016 in Collin County, Texas (the “Torchlight Lawsuit”). The Torchlight Lawsuit arose primarily out of Torchlight’s business dealings with Husky Ventures, Inc. (“Husky”) in Oklahoma. Husky and several of its employees and affiliates were also defendants in the Torchlight Lawsuit. As part of settlement negotiations between Husky and the Company in a separate lawsuit, Husky informed the Company that it had agreed to repurchase assets from Torchlight that Husky had previously sold to Torchlight (the “Torchlight Assets”). Husky offered to sell those Torchlight Assets to the Company. In the Purchase and Sale Agreement between Torchlight and Husky (the “Purchase and Sale Agreement”), Torchlight expressly acknowledged that the Torchlight Assets were to be sold to the Company and released the Company from any claims arising out of the sale of the Torchlight Assets. Despite this release, Torchlight alleged multiple causes of action against the Company and its officers and directors arising out of the sale of the Torchlight Assets and Torchlight’s other business dealings it had with Husky.

On August 17, 2016, plaintiffs nonsuited, without prejudice, their claims against the former chairman of the board.  On May 22, 2017, the court granted the Company’s motion for summary judgment and dismissed all of the plaintiffs’ claims against the Company and the Company’s other officers and directors in their entirety.  

The Company filed a counterclaim against Torchlight for breach of the release in the Purchase and Sale Agreement.  On April 26, 2018, the Court granted, in part, the Company’s motion for summary judgment on its breach-of-contract counterclaim and left for trial only the question of the Company’s damages.  On May 23, 2018, Torchlight and the Company settled the breach-of-contract counterclaim, and on May 24, 2018, the Court dismissed with prejudice all claims and counterclaims between Torchlight and the Company in the Torchlight Lawsuit.    

PennMarc Resources II, LP, et al v. Gastar Exploration USA, Inc., et al, (Civil Action No. 18-C-220 H.) Circuit Court of Marshall County, West Virginia; Venable Royalty, Ltd. et al v. Gastar Exploration USA, Inc., et al, (Civil Action No 18-C-227.) Circuit Court of Marshall County, West Virginia.  These lawsuits are related to a prior lawsuit filed by the same plaintiffs in 2017: PennMarc Resources II, LP, et al v. Gastar Exploration USA, Inc., et al, (Civil Action No17 C 214) The plaintiffs are royalty owners under various leases taken by or assigned to the Company.  The leases cover property in Marshall County, West Virginia.  The leases are among other assets that were assigned to THQ Appalachia, LLC pursuant to a purchase and sale agreement dated February 12, 2016.  In the original lawsuit, the plaintiffs alleged that the Company breached the leases by making deductions for post-production costs that were not authorized by the terms of the leases.  The plaintiffs also alleged that the unauthorized deductions were not shown on their monthly royalty statements and the failure to detail the deduction of these costs was fraudulent.  The plaintiffs asserted claims for breach of contract, breach of fiduciary duty and fraudulent concealment.  The plaintiffs sought compensatory damages and punitive damages.  The Company successfully moved to dismiss the plaintiffs’ claims in December 2017, arguing that some claims were subject to arbitration while others were premature because the plaintiffs had failed to provide written notice of a breach, as required by the leases.  The Court granted the Company’s motion to dismiss in July 2018 and dismissed the plaintiffs’ claims without prejudice.  After the motion was granted, a number of the plaintiffs complied with the leases’ pre-suit notification requirement by sending the Company formal notices of breach.  In its response to the notices, the Company asserted that it had paid royalties correctly during its ownership of the leases.  In October of 2018, PennMarc Resources II, LP refiled its lawsuit along with several of the other original plaintiffs.  Shortly thereafter, two more of the original plaintiffs, Venable Royalty, Ltd. and Venro, Ltd., filed a separate but identical lawsuit.  In both lawsuits, the plaintiffs allege the Company breached the leases by improperly deducting post-production costs.  The plaintiffs assert a claim for breach of contract and seek compensatory damages, equitable accounting, and declaratory relief.  The Company is still reviewing the lawsuits and has not yet filed an answer.     

Eagle Natrium LLC v. Gastar Exploration USA, Inc., Cause No. GD-14-7208, In the Court of Common Pleas of Allegheny County, Pennsylvania.On April 22, 2014, Eagle Natrium LLC (“Eagle”), a wholly-owned subsidiary of Axiall Corporation, filed a complaint against the Company in the Court of Common Pleas of Allegheny County, Pennsylvania seeking to enjoin Gastar’s hydraulic fracturing and completion operations on three wells drilled from Gastar’s Goudy pad in Marshall County, West Virginia, or conducting any activity that poses a substantial risk of harm to Eagle’s brine operations. Gastar was the operator of approximately 16,000 acres in Marshall County, West Virginia, including a 3,300 gross acre oil and gas lease adjacent to Eagle’s facilities. Eagle asserted its right to relief based on certain of the lessor’s rights which were assigned to Eagle by the lessor solely as they relate to the brine and related facilities. A hearing on the request for preliminary injunction was held in the summer of 2014. After considering the evidence presented at the hearing and the party’s briefing, the court issued an order on October 21, 2014 denying the request for a preliminary injunction. In January 2015, Gastar began completion operations and has since completed the three wells drilled from its Goudy pad that formed the basis of Eagle’s complaint.  In 2016, the Company amended its answer and has added counterclaims seeking damages from Eagle as a result of the proceedings. Specifically, Gastar has asserted a breach of contract claim, seeking damages for lost revenues, rig up and rig down costs and attorney’s fees relating to the Pennsylvania lawsuit filed by Eagle. Eagle has also maintained its breach of contract claim against the Company.  The Court has bifurcated the proceeding into a separate liability and damages phase.  On June 25, 2018, the Court commenced a six-day bench trial on liability.  A decision on the parties’ respective liability remains pending.  

The Company has been expensing legal costs on these proceedings as they are incurred.

The Company is party to various legal proceedings arising in the normal course of business. The ultimate outcome of each of these matters cannot be absolutely determined, and the liability the Company may ultimately incur with respect to any one of these matters in the event of a negative outcome may be in excess of amounts currently accrued for with respect to such matters. Net of available insurance and performance of contractual defense and indemnity obligations, where applicable, management does not believe any such matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows.

The commencement of the Chapter 11 Cases automatically stayed certain actions against the Company, including actions to collect pre-petition indebtedness or to exercise control over the property of the Company’s bankruptcy estates, and the Company intends to seek authority to pay all general claims in the ordinary course of business notwithstanding the commencement of the Chapter 11 Cases in a manner consistent with the RSA.  The Plan filed in the Chapter 11 Cases, if confirmed as contemplated by the RSA, will provide for the treatment of claims against the Company’s bankruptcy estates, including pre-petition liabilities that have not otherwise been satisfied or addressed during the Chapter 11 Cases.

Schuyler entered into retention bonus letters (each a “Retention Bonus Letter”) providing that each such executive will receive a cash payment (“Retention Bonus”), representing a certain percentage of his base salary, paid in a lump sum in cash on or before August 17, 2018.  In the event the executive’s employment is terminated (i) by the Company for cause (as defined in the Retention Agreement) or (ii) due to his voluntarily resignation, the executive will be required to repay to the Company 100% of the Retention Bonus (net of any taxes withheld from same) if such termination occurs before December 31, 2018 and 50% of the Retention Bonus (net of taxes withheld from same) if such termination occurs after December 31, 2018 and before July 1, 2019 (the “Repayment Obligation”). The Repayment Obligation will cease in the event that the Company fails to pay the executive’s base salary in accordance with the Company’s normal payroll practices and fails to correct any such failure within five (5) days of written notice from the executive or upon the occurrence of a change in control (as defined in the Retention Bonus Letters) of the Company. The Repayment Obligation set forth in Mr. Schuyler’s Retention Bonus Letter is reduced on a straight line basis from 100% (if termination occurs before September 1, 2018) to 0% (if termination occurs any time after June 1, 2019) for each additional month that he remains employed by the Company.

On October 25, 2018, Gastar entered into amendments (the “Retention Bonus Amendments”) to theRetention Bonus Letters.  The Retention Bonus Amendments amend each of the respective Retention Bonus Letters to specify that the definition of “Change in Control” therein does not include a change of control resulting from the acquisition of a controlling interest from the Chapter 11 Cases or an acquisition by Ares or its affiliates.  In addition, the Retention Bonus Amendments with Mr. Gerlich and Mr. Roberts provide that 100% of the retention bonus is repayable by the employee if he terminates employment without Good Reason or if the Company terminates his employment with Cause (as such terms are defined in the Retention Bonus Letters) prior to February 28, 2019, and 50% of the retention bonus is payable by the employee if such a termination occurs between February 28, 2019 and April 30, 2019.

Accounting Policies [Abstract]

Basis of Accounting

The unaudited interim condensed consolidated financial statements of the Company included herein are stated in U.S. dollars and were prepared from the records of the Company by management in accordance with U.S. GAAP applicable to interim financial statements and reflect all normal and recurring adjustments, which are, in the opinion of management, necessary to provide a fair presentation of the results of operations and financial position for the interim periods. Such financial statements conform to the presentation reflected in the 2017 Form 10-K except for revenue which, for the three and nine months ended September 30, 2018, is presented net of treating, transportation and gathering costs pursuant to current authoritative accounting guidance. The current interim period reported herein should be read in conjunction with the financial statements and accompanying notes, including Item 8. “Financial Statements and Supplementary Data, Note 3 – Summary of Significant Accounting Policies,” included in the 2017 Form 10-K.

Subsequent Events

Subsequent Events

In preparing these financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued and has disclosed certain subsequent events in these condensed consolidated financial statements, as appropriate.

Restricted Cash

Restricted Cash

Cash and cash equivalents that are restricted as to withdrawal or use under the terms of certain contractual agreements are recorded in restricted cash in the current assets section of our consolidated balance sheet.  At September 30, 2018 and December 31, 2017, the Company had restricted cash of $25,000 and $370,000, respectively.

Accounts Receivable

Accounts Receivable

Accounts receivable are reported net of the allowance for doubtful accounts.  The allowance for doubtful accounts is determined based on a review of the Company’s receivables.  Receivable accounts are charged off when collection efforts have failed or the account is deemed uncollectible.  During 2016, the Company determined that a receivable account from a third-party natural gas and NGLs purchaser would no longer be collectible as a result of the third-party purchaser filing for bankruptcy.  A summary of the activity related to the allowance for doubtful accounts is as follows:

	September 30, 2018		December 31, 2017
	(in thousands)
Allowance for doubtful accounts, beginning of period	$	1,953	$	1,953

Recent Accounting Developments

Recent Accounting Developments

Leases.  In February 2016, the FASB issued updated guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and enhance disclosures regarding key information about leasing arrangements.  Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Additionally, in January 2018, the FASB issued an amendment to the updated guidance to permit an entity to elect an optional transition practical expedient to not evaluate under the new guidance land easements that exist or expire before the adoption of the updated guidance and that were not previously accounted for as leases under previous guidance.  In July 2018, the FASB issued an additional amendment that permits an entity to elect an additional transition method to the existing modified retrospective transition requirements.  Under the new transition method, an entity could adopt the provisions of this update by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption.  Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard may continue to be in accordance with the previous lease guidance.  This amendment also allows a practical expedient that permits lessors to not separate non-lease components from the associated lease component if certain conditions are present. The amendments in this update are effective beginning on January 1, 2019 and should be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements.  Early adoption is permitted.  The Company has commenced analyzing its lease contracts but has not yet determined what the effects of adopting this updated guidance will be on its consolidated financial statements.  The Company will adopt this updated guidance in the first quarter 2019 and anticipates that it will recognize a right of use asset and lease liability on the adoption date. The Company plans to apply practical expedients provided in the standards update that allow, among other things, not to reassess contracts that commenced prior to the adoption. The Company also anticipates electing a policy not to recognize right of use assets and lease liabilities related to short-term and immaterial leases.

Revenue Recognition.  On January 1, 2018, the Company adopted Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“ASC 606”) using the modified retrospective method of transition.  Under the modified retrospective approach, the standard has been applied to all existing contracts as of the date of initial application with the cumulative effect of applying the standard, if any, recognized in retained earnings.  

The impact of adoption on our current period results is as follows:

	Three Months Ended September 30, 2018							Nine Months Ended September 30, 2018
	Under ASC 606		Under ASC 605		Increase (Decrease)			Under ASC 606		Under ASC 605		Increase (Decrease)
	(in thousands)							(in thousands)
Revenues:
Oil and condensate	$	17,436	$	17,448	$	(12	)	$	54,497	$	54,530	$	(33	)
Natural gas		1,986		2,752		(766	)		5,618		7,708		(2,090	)
NGLs		2,092		2,593		(501	)		7,315		8,629		(1,314	)
Total oil and condensate, natural gas and NGLs revenues	$	21,514	$	22,793	$	(1,279	)	$	67,430	$	70,867	$	(3,437	)
Expenses:
Transportation, treating and gathering	$	—	$	1,279	$	(1,279	)	$	—	$	3,437	$	(3,437	)
Net income (loss)	$	21,514	$	21,514	$	—		$	67,430	$	67,430	$	—
Retained earnings	$	21,514	$	21,514	$	—		$	67,430	$	67,430	$	—

The primary impact to our revenues as a result of the adoption of ASC 606 is the recording of transportation, treating, gathering and compression expenses (“Post-Production Expenses”) as a direct reduction to revenues instead of our historical practice of presenting such expenses gross in transportation, treating and gathering.  These changes are due to the conclusion that the Company represents the agent in the sale of natural gas and NGLs under its gas processing and marketing agreements with midstream entities in accordance with the control model in ASC 606.  As a result, the Company is required to record revenue on a net basis for amounts expected to be received from third-party customers through the marketing process, with Post-Production Expenses incurred subsequent to control of the product(s) transferring to the midstream entity at the wellhead being netted against revenue.

Revenue from Contract with Customers (Narrative) (Details)	9 Months Ended

Revenue From Contract With Customer [Abstract]
Significant judgments	Principal versus Agent The Company engages in various types of transactions in which midstream entities process its wet gas and, in some scenarios, subsequently market resulting NGLs and residue gas to third-party customers on the Company’s behalf, such as gas processing contracts. These types of transactions require judgment to determine whether the Company is the principal or the agent in the contract and, as a result, whether revenues are recorded gross or net. For the Company’s existing contracts, the Company has determined that it represents the agent in the sale of products under certain gas processing and marketing agreements with midstream entities in accordance with the control model in ASC 606. As a result, the Company presents revenue on a net basis for amounts expected to be received from third-party customers through the marketing process, with Post-Production Expenses incurred subsequent to control of the product(s) transferring to the midstream entity being netted against revenue.
Revenue, practical expedient, nondisclosure of transaction price allocation to remaining performance obligation	true
Performance obligation, description of timing	The Company records revenue in the month its production is delivered to the purchaser. However, settlement statements and payment may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production that was delivered to the purchaser and the price that will be received for the sale of the product including any transportation and other deductions.

Executive
Loss Contingencies [Line Items]
Retention bonus, terms				On August 31, 2018, the Company, on the one hand, and each of Stephen P. Roberts, Michael A. Gerlich and Jerry R. Schuyler entered into retention bonus letters (each a “Retention Bonus Letter”) providing that each such executive will receive a cash payment (“Retention Bonus”), representing a certain percentage of his base salary, paid in a lump sum in cash on or before August 17, 2018. In the event the executive’s employment is terminated (i) by the Company for cause (as defined in the Retention Agreement) or (ii) due to his voluntarily resignation, the executive will be required to repay to the Company 100% of the Retention Bonus (net of any taxes withheld from same) if such termination occurs before December 31, 2018 and 50% of the Retention Bonus (net of taxes withheld from same) if such termination occurs after December 31, 2018 and before July 1, 2019 (the “Repayment Obligation”). The Repayment Obligation will cease in the event that the Company fails to pay the executive’s base salary in accordance with the Company’s normal payroll practices and fails to correct any such failure within five (5) days of written notice from the executive or upon the occurrence of a change in control (as defined in the Retention Bonus Letters) of the Company. The Repayment Obligation set forth in Mr. Schuyler’s Retention Bonus Letter is reduced on a straight line basis from 100% (if termination occurs before September 1, 2018) to 0% (if termination occurs any time after June 1, 2019) for each additional month that he remains employed by the Company.
Retention bonus amendments, terms				On October 25, 2018, Gastar entered into amendments (the “Retention Bonus Amendments”) to the Retention Bonus Letters. The Retention Bonus Amendments amend each of the respective Retention Bonus Letters to specify that the definition of “Change in Control” therein does not include a change of control resulting from the acquisition of a controlling interest from the Chapter 11 Cases or an acquisition by Ares or its affiliates. In addition, the Retention Bonus Amendments with Mr. Gerlich and Mr. Roberts provide that 100% of the retention bonus is repayable by the employee if he terminates employment without Good Reason or if the Company terminates his employment with Cause (as such terms are defined in the Retention Bonus Letters) prior to February 28, 2019, and 50% of the retention bonus is payable by the employee if such a termination occurs between February 28, 2019 and April 30, 2019.
