NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—Description of Business and Significant Accounting Policies

GOODRICH PETROLEUM CORPORATION AND SUBSIDIARY

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Inventory –Inventory consists of casing and tubulars that are expected to be used in our capital drilling program. Inventory is carried on the Consolidated Balance Sheets at the lower of cost or market.

Property and Equipment—Under US GAAP, two acceptable methods of accounting for oil and natural gas properties are allowed. These are the Successful Efforts Method and the Full Cost Method. Entities engaged in the production of oil and natural gas have the option of selecting either method for application in the accounting for their properties. The principal differences between the two methods are in the treatment of exploration costs, the computation of Depreciation, Depletion and Amortization (“DD&A”) expense and the assessment of impairment of oil and natural gas properties. We use the Full Cost Method to account for our investment in oil and gas properties.

Under the Full Cost Method, we capitalize all costs associated with acquisitions, exploration, development and estimated abandonment costs. We capitalize internal costs that can be directly identified with the acquisition of leasehold, as well as drilling and completion activities, but do not include any costs related to production, general corporate overhead or similar activities. Unevaluated property costs are excluded from the amortization base until we make a determination as to the existence of proved reserves on the respective property or impairment. We review our unevaluated properties at the end of each quarter to determine whether the costs should be reclassified to proved oil and natural gas properties and thereby subject to DD&A and the full cost ceiling test. For the three months ended September 30, 2018 and 2017, we transferred $5.7 million and $5.8 million, respectively, from unevaluated properties to proved oil and natural gas properties. For the nine months ended September 30, 2018 and 2017, we transferred $6.1 million and $18.6 million, respectively, from unevaluated properties to proved oil and natural gas properties. Our sales of oil and natural gas properties are accounted for as adjustments to net proved oil and natural gas properties with no gain or loss recognized, unless the adjustment would significantly alter the relationship between capitalized costs and proved reserves.

We amortize our investment in oil and natural gas properties through DD&A expense using the units of production (the “UOP”) method. An amortization rate is calculated based on total proved reserves converted to equivalent thousand cubic feet of natural gas (“Mcfe”) as the denominator and the net book value of evaluated oil and gas asset together with the estimated future development cost of the proved undeveloped reserves as the numerator. The rate calculated per Mcfe is applied against the periods' production also converted to Mcfe to arrive at the periods' DD&A expense.

Depreciation of furniture, fixtures and equipment, consisting of office furniture, computer hardware and software and leasehold improvements, is computed using the straight-line method over their estimated useful lives, which vary from three to five years.

Full Cost Ceiling Test—The Full Cost Method requires that at the conclusion of each financial reporting period, the present value of estimated future net cash flows from proved reserves (adjusted for hedges and excluding cash flows related to estimated abandonment costs), be compared to the net capitalized costs of proved oil and natural gas properties, net of related deferred taxes. This comparison is referred to as a "ceiling test". If the net capitalized costs of proved oil and natural gas properties exceed the estimated discounted future net cash flows from proved reserves, we are required to write-down the value of our oil and natural gas properties to the value of the discounted cash flows. Estimated future net cash flows from proved reserves are calculated based on a 12-month average pricing assumption.

There were no Full Cost Ceiling Test write-downs for the three or nine months ended September 30, 2018 or 2017.

Fair Value Measurement—Fair value is defined as the price 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. The fair value of an asset should reflect its highest and best use by market participants, whether in-use or an in-exchange valuation premise. The fair value of a liability should reflect the risk of non-performance, which includes, among other things, our credit risk.

We use various methods, including the income approach and market approach, to determine the fair values of our financial instruments that are measured at fair value on a recurring basis, which depend on a number of factors, including the availability of observable market data over the contractual term of the underlying instrument. For some of our instruments, the fair value is calculated based on directly observable market data or data available for similar instruments in similar markets. For other instruments, the fair value may be calculated based on these inputs as well as other assumptions related to estimates of future settlements of these instruments. We separate our financial instruments into three Levels (Levels 1, 2 and 3) based on our assessment of the availability of observable market data and the significance of non-observable data used to determine the fair value of our instruments. Our assessment of an instrument can change over time based on the maturity or liquidity of the instrument, which could result in a change in the classification of the instruments between Levels.

7

GOODRICH PETROLEUM CORPORATION AND SUBSIDIARY

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Each of these Levels and our corresponding instruments classified by Level are further described below:

• Level 1 Inputs— unadjusted quoted market prices in active markets for identical assets or liabilities. We have no Level 1 instruments;

• Level 2 Inputs— quotes that are derived principally from or corroborated by observable market data. Included in this Level are our 2017 Senior Credit Facility and commodity derivatives whose fair values are based on third-party quotes or available interest rate information and commodity pricing data obtained from third party pricing sources and our creditworthiness or that of our counterparties; and

• Level 3 Inputs— unobservable inputs for the asset or liability, such as discounted cash flow models or valuations, based on our various assumptions and future commodity prices. Included in this Level would be our initial measurement of asset retirement obligations.

As of September 30, 2018 and December 31, 2017, the carrying amounts of our cash and cash equivalents, trade receivables and payables represented fair value because of the short-term nature of these instruments.

Asset Retirement Obligations—Asset retirement obligations are related to the abandonment and site restoration requirements that result from the exploration and development of our oil and natural gas properties. We record the fair value of a liability for an asset retirement obligation in the period in which it is incurred and a corresponding increase in the carrying amount of the related long-lived asset. Accretion expense is included in “Depreciation, depletion and amortization” on our Consolidated Statements of Operations. See Note 3.

The estimated fair value of the Company’s asset retirement obligations at inception is determined by utilizing the income approach by applying a credit-adjusted risk-free rate, which takes into account the Company’s credit risk, the time value of money, and the current economic state, to the undiscounted expected abandonment cash flows. Given the unobservable nature of the inputs, the initial measurement of the asset retirement obligations was classified as Level 3 in the fair value hierarchy.

Revenue Recognition—Oil and natural gas revenues are recognized upon delivery of our produced oil and natural gas volumes to our customers. Revenues from the production of crude oil and natural gas properties in which we have an interest with other producers are recognized in accordance with when the producing company records revenue on those volumes. We record a liability or an asset for natural gas balancing when we have sold more or less than our working interest share of natural gas production, respectively. AtSeptember 30, 2018and December 31, 2017, the net liability for natural gas balancing was immaterial. Differences between actual production and net working interest volumes are routinely adjusted. See Note 2.

Derivative Instruments—We use derivative instruments such as futures, forwards, options, collars and swaps for purposes of hedging our exposure to fluctuations in the price of crude oil and natural gas and to hedge our exposure to changing interest rates. Accounting standards related to derivative instruments and hedging activities require that all derivative instruments subject to the requirements of those standards be measured at fair value and recognized as assets or liabilities in the balance sheet. We offset the fair value of our asset and liability positions with the same counterparty for each commodity type. Changes in fair value are required to be recognized in earnings unless specific hedge accounting criteria are met. All of our realized gain or losses on our derivative contracts are the result of cash settlements. We have not designated any of our derivative contracts as hedges; accordingly, changes in fair value are reflected in earnings. See Note 8.

Income Taxes—We account for income taxes, as required, under the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

We recognize, as required, the financial statement benefit of an uncertain tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. See Note 7.

Net Income or Net Loss Per Share—Basic income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders for each reporting period by the weighted-average number of common shares outstanding

GOODRICH PETROLEUM CORPORATION AND SUBSIDIARY

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

during the period. Diluted income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders for each reporting period by the weighted-average number of common shares outstanding during the period, plus the effects of potentially dilutive restricted stock calculated using the treasury stock method and the potential dilutive effect of the conversion of convertible securities, such as warrants and convertible notes, into shares of our common stock. See Note 6.

Commitments and Contingencies—Liabilities for loss contingencies, including environmental remediation costs, arising from claims, assessments, litigation, fines and penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Recoveries from third parties, when probable of realization, are separately recorded and are not offset against the related environmental liability. See Note 9.

Share-Based Compensation—We account for our share-based transactions using the fair value as of the grant date and recognize compensation expense over the requisite service period.

Guarantee—As of September 30, 2018, Goodrich Petroleum Company LLC, the wholly owned subsidiary of Goodrich Petroleum Corporation, was the Subsidiary Guarantor of our 13.50% Convertible Second Lien Senior Secured notes due 2019 (the “Convertible Second Lien Notes”).

Debt Issuance Cost—The Company records debt issuance costs associated with its Convertible Second Lien Notes as a contra balance to long term debt, net in our Consolidated Balance Sheets, which is amortized straight-line over the life of the Convertible Second Lien Notes. Debt issuance costs associated with our revolving credit facility debt are recorded in other assets in our Consolidated Balance Sheets, which is amortized straight-line over the life of such debt.

New Accounting Pronouncements

On August 28, 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820 including the removal, modification and addition of certain disclosure requirements. For all entities, the amendments in this ASU are effective for fiscal periods beginning after December 15, 2019, including interim periods therein. We are evaluating the expected impact these amendments will have on our consolidated financial statements.

On June 20, 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. For public entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2018. We have not granted or issued share-based payments to nonemployees. We have evaluated the provisions of this ASU and do not expect it to have a material impact on our consolidated financial statements.

On March 13, 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740). The ASU adds seven paragraphs to the Accounting Standards Codification “ASC” 740, Income Taxes, that contain SEC guidance related to Staff Accounting Bulletin 118 (“Income Tax Accounting Implications of the Tax Cuts and Jobs Act”) as a result of the tax legislation passed in 2017 known as the “Tax Cuts and Jobs Act”. Specifically, the staff intended to address situations where the accounting under ASC Topic 740 is incomplete for certain income tax effects of the Tax Cuts and Jobs Act upon issuance of an entity’s financial statements for the reporting period in which the Tax Cuts and Jobs Act was enacted. The Company notes that it has considered the updates to ASC 740 as a result of the Tax Cuts and Jobs Act and has prepared its consolidated financial statements in accordance with the Tax Cuts and Jobs Act. See Note 7 for further discussion.

On August 28, 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU is intended to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this ASU make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP based on the feedback received from preparers, auditors, users, and other stakeholders. For public entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2018. We do not expect this ASU to have a material

impact on our consolidated financial statements as we currently mark-to-market all of our derivative positions; however, we are evaluating the impact of this ASU should we choose to utilize hedge accounting in the future.

On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842) and subsequently issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements in July 2018. The key difference between the existing standards and ASU 2016-02 is the requirement for lessees to recognize on their balance sheet all lease contracts with lease terms greater than 12 months, including operating leases. Specifically, lessees are required to recognize on the balance sheet at lease commencement, both (i) a right-of-use asset, representing the lessee’s right to use the leased asset over the term of the lease, and (ii) a lease liability, representing the lessee’s contractual obligation to make lease payments over the term of the lease. For lessees, ASU 2016-02 requires classification of leases as either operating or finance leases, which are similar to the current operating and capital lease classifications. However, the distinction between these two classifications under the ASU does not relate to balance sheet treatment, but relate to treatment and recognition in the statements of income and cash flows. Lessor accounting is largely unchanged from current US GAAP. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, for public entities. Early application is permitted. The Company is carrying out its project plan to guide the implementation of ASU 2016-02, which includes assessing our portfolio of leases, determining a process for ensuring completeness of our repository of active leases, determining financial statement impacts and preparing for disclosure requirements under Topic 842. We have not yet completed our evaluation of the impact the new lease accounting guidance will have on our consolidated financial statements; however, we do expect to recognize right of use assets and lease liabilities for our operating leases with terms longer than 12 months in the Consolidated Balance Sheets upon adoption.

NOTE 2—Revenue Recognition

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers, and the series of related ASU's that followed under ASC Topic 606 (collectively, “Topic 606”).Under Topic 606, revenue will generally be recognized upon delivery of our produced oil and natural gas volumes to our customers. Our customer sales contracts include oil and natural gas sales. Under Topic 606, each unit (Mcf or barrel) of commodity product represents a separate performance obligation which is sold at variable prices, determinable on a monthly basis. The pricing provisions of our contracts are primarily tied to a market index with certain adjustments based on factors such as delivery, product quality and prevailing supply and demand conditions in the geographic areas in which we operate. We will allocate the transaction price to each performance obligation and recognize revenue upon delivery of the commodity product when the customer obtains control. Control of our produced natural gas volumes passes to our customers at specific metered points indicated in our natural gas contracts. Similarly, control of our produced oil volumes passes to our customers when the oil is measured either by a trucking oil ticket or by a meter when entering an oil pipeline. The Company has no control over the commodities after those points and the measurement at those points dictates the amount on which the customer's payment is based. Our oil and natural gas revenue streams include volumes burdened by royalty and other joint owner working interests. Our revenues are recorded and presented on our financial statements net of the royalty and other joint owner working interests. Our revenue stream does not include any payments for services or ancillary items other than sale of oil and natural gas.

We record revenue in the month our production is delivered to the purchaser. However, settlement statements and payments for our oil and natural gas sales may not be received for up to 60 days after the date production is delivered, and as a result, we are required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. We record any differences, which historically have not been significant, between the actual amounts ultimately received and the original estimates in the period they become finalized. As of September 30, 2018 and December 31, 2017, receivables from contracts with customers were $9.3 million and $5.0 million, respectively.

Topic 606 will not change our pattern of timing of revenue recognition. We utilized the full retrospective method for adoption of Topic 606, and in accordance with this method our consolidated financial statements for periods prior to January 1, 2018 were not materially affected or revised. We also do not anticipate a material impact on our financial statements on an ongoing basis.

Exit Credit Facility

On October 12, 2016, upon consummation of the plan of reorganization and emergence from bankruptcy, the Company entered into an Exit Credit Agreement (the “Exit Credit Agreement”) with the Subsidiary, as borrower (the “Borrower”), and Wells Fargo Bank, National Association, as administrative agent, and certain other lenders party thereto. Pursuant to the Exit Credit Agreement, the lenders party thereto agreed to provide the Borrower with a $20.0 million senior secured term loan credit facility (the “Exit Credit Facility”). On October 17, 2017, the Exit Credit Facility was paid off in full and replaced with the 2017 Senior Credit Facility described below.

2017 Senior Credit Facility

On October 17, 2017, the Company entered into the Amended and Restated Senior Secured Revolving Credit Agreement (the “Credit Agreement”) with the Subsidiary, as borrower, JP Morgan Chase Bank, N.A. as administrative agent, and certain lenders that are party thereto, which provides for revolving loans of up to the borrowing base then in effect, as amended by a first amendment and a second amendment entered into on October 15, 2018 and effective as of September 30, 2018, which increased the borrowing base to $75.0 million and provided for a minimum current ratio financial covenant beginning with the quarter ending on December 31, 2018 (as so amended, “2017 Senior Credit Facility”). The 2017 Senior Credit Facility amended, restated and refinanced the obligations under the Exit Credit Facility. The 2017 Senior Credit Facility matures (a) October 17, 2021 or (b) if the Convertible Second Lien Notes (as defined below) have not been voluntarily redeemed, repurchased, refinanced or otherwise retired by December 30, 2019, December 30, 2019. The maximum credit amount under the 2017 Senior Credit Facility at September 30, 2018 was $250.0 million with a borrowing base of $75.0 million subject to an elected draw limit of $50.0 million. The borrowing base is scheduled to be redetermined in March and September of each calendar year, and is subject to additional adjustments from time to time, including for asset sales, elimination or reduction of hedge positions and incurrence of other debt. Additionally, each of the Borrower and the administrative agent may request one unscheduled redetermination of the borrowing base between scheduled redeterminations. The amount of the borrowing base is determined by the lenders in their sole discretion and consistent with their oil and gas lending criteria at the time of the relevant redetermination. The Company may also request the issuance of letters of credit under the Credit Agreement in an aggregate amount up to $10.0 million, which reduce the amount of available borrowings under the borrowing base in the amount of such issued and outstanding letters of credit.

All amounts outstanding under the 2017 Senior Credit Facility bear interest at a rate per annum equal to, at the Company's option, either (i) the alternative base rate plus an applicable margin ranging from 1.75% to 2.75%, depending on the percentage of the borrowing base that is utilized, or (ii) adjusted LIBOR plus an applicable margin from 2.75% to 3.75%, depending on the percentage of the borrowing base that is utilized. Undrawn amounts under the 2017 Senior Credit Facility are subject to a 0.50% commitment fee. To the extent that a payment default exists and is continuing, all amounts outstanding under the 2017 Senior Credit Facility will bear interest at 2.00% per annum above the rate and margin otherwise applicable thereto. As of September 30, 2018, the interest rate on the 2017 Senior Credit Facility was 7.25%.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

The 2017 Senior Credit Facility also contains certain financial covenants, including (i) the maintenance of a ratio of Total Debt (as defined in the Credit Agreement) to EBITDAX not to exceed 4.00 to 1.00 as of the last day of any fiscal quarter, (ii) in accordance with the second amendment to the Credit Agreement, beginning with the quarter ended December 31, 2018, a current ratio (based on the ratio of current assets to current liabilities) not to be less than 1.00 to 1.00 and (iii) until no Convertible Second Lien Notes remain outstanding, (A) the maintenance of a ratio of Total Proved PV10% attributable to the Company’s and Borrower’s Proved Reserves (as defined in the Credit Agreement) to Total Secured Debt (net of any Unrestricted Cash not to exceed $10.0 million) not to be less than 1.50 to 1.00 and (B) minimum liquidity requirements. See Note 11 Subsequent Events for more information on the second amendment to the Credit Agreement.

The obligations under the Credit Agreement are guaranteed by the Company and are secured by a first lien security interest in substantially all of the assets of the Company and the Subsidiary.

As of September 30, 2018, the Company had $15.0 million outstanding borrowings. The Company also had $0.5 million of unamortized debt issuance costs recorded as of September 30, 2018 related to the 2017 Senior Credit Facility.

As of September 30, 2018, the Company was in compliance with all covenants within the 2017 Senior Credit Facility.

13.50% Convertible Second Lien Senior Secured Notes Due 2019

On October 12, 2016, upon emergence from bankruptcy, the Company and the Subsidiary, entered into a purchase agreement (the “Purchase Agreement”) with each entity identified as a Shenkman Purchaser on Appendix A to the Purchase Agreement (collectively, the “Shenkman Purchasers”), CVC Capital Partners (acting through such of its affiliates to managed funds as it deems appropriate), J.P. Morgan Securities LLC (acting through such of its affiliates or managed funds as it deems appropriate), Franklin Advisers, Inc. (as investment manager on behalf of certain funds and accounts), O’Connor Global Multi-Strategy Alpha Master Limited and Nineteen 77 Global Multi-Strategy Alpha (Levered) Master Limited (collectively, and together with each of their successors and assigns, the “Purchasers”), in connection with the issuance of $40.0 million aggregate principal amount of the Company’s 13.50% Convertible Second Lien Senior Secured Notes due 2019 (the “Convertible Second Lien Notes”).

The aggregate principal amount of the Convertible Second Lien Notes is convertible at the option of the Purchasers at any time prior to the scheduled maturity date at $21.33 per share, subject to adjustments. At closing, the Purchasers were issued 10-year costless warrants to acquire 2.5 million shares of common stock. Holders of the Convertible Second Lien Notes have a second priority lien on all assets of the Company, and have a continuing right to appoint two members to our Board of Directors (the “Board”) as long as the Convertible Second Lien Notes are outstanding.

The Convertible Second Lien Notes as set forth in the agreement, will mature on August 30, 2019 or six months after the maturity of our current revolving credit facility but in no event later than March 30, 2020. The 2017 Senior Credit Facility matures no earlier than December 30, 2019; consequently, the Convertible Second Lien Notes will mature on March 30, 2020. The Convertible Second Lien Notes bear interest at the rate of 13.50% per annum, payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year. The Company may elect to pay all or any portion of interest in-kind on the then outstanding principal amount of the Convertible Second Lien Notes by increasing the principal amount of the outstanding Convertible Second Lien Notes or by issuing additional Second Lien Notes (“PIK Interest Notes”). The PIK Interest Notes are not convertible. During such time as the Exit Credit Agreement (but not any refinancing or replacement thereof) was in effect, interest on the Convertible Second Lien Notes had to be paid in-kind. As to the new 2017 Senior Credit Facility, interest on the Convertible Second Lien Notes must be paid in-kind; provided however, that after the quarter ending March 31, 2018, if (i) there is no default, event of default or borrowing base deficiency that has occurred and is continuing, (ii) the ratio of total debt to EBITDAX as defined under the 2017 Senior Credit Facility is less than 1.75 to 1.0 and (iii) the unused borrowing base is at least 25%, then the Company can pay the interest on the Convertible Second Lien Notes in cash, at its election.

The indenture governing the Convertible Second Lien Notes (the “Indenture”) contains certain covenants pertaining to us and our subsidiary, including delivery of financial reports; environmental matters; conduct of business; use of proceeds; operation and maintenance of properties; collateral and guarantee requirements; indebtedness; liens; dividends and distributions; limits on sale of assets and stock; business activities; transactions with affiliates; and changes of control.

The Indenture also contains certain financial covenants, including the maintenance of (i) a Total Proved Asset Coverage Ratio (as defined in the Exit Credit Agreement) not to be less than 1.50 to 1.00 after September 30, 2017, to be determined as of January 1 and July 1 of each year and (ii) minimum liquidity requirements.

Upon issuance of the Convertible Second Lien Notes in October 2016, in accordance with accounting standards related to convertible debt instruments that may be settled in cash upon conversion as well as warrants on the debt instrument, we recorded a debt discount of $11.0 million, thereby reducing the $40.0 million carrying value upon issuance to $29.0 million and recorded an equity component of $11.0 million. The debt discount is amortized using the effective interest rate method based upon an original term through August 30, 2019. $5.1 million of debt discount remains to be amortized on the Convertible Second Lien Notes as of September 30, 2018.

As of September 30, 2018, the Company was in compliance with all covenants within the Indenture governing the Convertible Second Lien Notes.

NOTE 5—Equity

During the three months ended September 30, 2018, no holders of the 10 year costless warrants associated with the Convertible Second Lien Notes exercised warrants. During the nine months ended September 30, 2018, certain holders of the 10 year costless warrants associated with the Convertible Second Lien Notes exercised 862,812 warrants for the issuance of an equal amount of our one cent par value common stock. The Company received cash for the one cent par value for the issuance of 315,937 common shares. As of September 30, 2018, 207,500 of such warrants remain un-exercised.

During the three months ended September 30, 2017, certain holders of the 10 year costless warrants associated with the Convertible Second Lien Notes exercised 54,687 warrants for the issuance of an equal amount of our one cent par value common stock. The Company received cash for the one cent par value for issuance of 54,687 common shares. During the nine months ended September 30, 2017, certain holders of the 10 year costless warrants associated with the Convertible Second Lien Notes exercised 1,429,687 warrants for the issuance of an equal amount of our one cent par value common stock. The Company received cash for the one cent par value for issuance of 679,687 common shares and the remaining common shares were issued cashless, which resulted in 564 shares repurchased by the Company and held in treasury stock. These treasury stock shares were subsequently retired.

The Company had no material vestings of its share based compensation units during the three or nine months ended September 30, 2018 or 2017.

The range of common stock shares which may be earned ranges from zero to 250% of the initial performance units granted.

NOTE 7—Income Taxes

We recorded no income tax expense or benefit for the three or nine months ended September 30, 2018 or 2017. We recorded a valuation allowance for our net deferred tax asset at December 31, 2016. The valuation allowance was $86.7 million at December 31, 2017, which resulted in a net non-current deferred tax asset of $0.9 million appearing on our statement of financial position. We recorded this valuation allowance at this date after an evaluation of all available evidence (including our

GOODRICH PETROLEUM CORPORATION AND SUBSIDIARY

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

recent history of net operating losses in 2017 and prior years) that led to a conclusion that based upon the more-likely-than-not standard of the accounting literature, these deferred tax assets were unrecoverable. The tax benefit recorded is due to Alternative Minimum Tax (“AMT”) credits that are expected to be recognized by the Company, which have been reduced for the anticipated sequestration. During the three months ended September 30, 2018, the Company estimated it would receive $0.2 million in AMT credits in 2018 and therefore setup an accounts receivable balance for that amount. The remaining $0.7 million of AMT credits, which is less anticipated sequestration, remain recorded as a deferred tax asset and are expected to be fully refundable in tax years 2019 - 2021 regardless of the Company's regular tax liability as a result of the repeal of the Corporate AMT under the Tax Cuts and Jobs Act. The Company no longer has a valuation allowance recorded against our estimate of refundable AMT credits. Considering the Company’s taxable income forecasts, our assessment of the realization of our deferred tax assets has not changed, and we continue to maintain a full valuation allowance for our net deferred tax assets as of September 30, 2018 aside from the deferred tax asset related to the AMT credits.

As of September 30, 2018, we have no unrecognized tax benefits. There were no significant changes to the calculation since December 31, 2017.

On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to

as the “Tax Cuts and Jobs Act”, resulting in significant modifications to existing law. Our financial statements for the year ended December 31, 2017 and now for the three and nine months ended September 30, 2018 reflect the effects of the Tax Cuts and Jobs Act which includes a reduction in the corporate tax rate from 35% to 21% effective January 1, 2018, as well as other changes. The Company follows the guidance in SEC Staff Accounting Bulletin 118 (“SAB 118”), which provides additional clarification regarding the application of ASC Topic 740 in situations where the Company does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act for the reporting period in which the Tax Cuts and Jobs Act was enacted. SAB 118 provides for a measurement period beginning in the reporting period that includes the Tax Cuts and Jobs Act’s enactment date and ending when the Company has obtained, prepared, and analyzed the information needed in order to complete the accounting requirements but in no circumstances should the measurement period extend beyond one year from the enactment date. We calculated the impact of the Tax Cuts and Jobs Act in our year ended December 31, 2017 income tax provision in accordance with our understanding of the Tax Cuts and Jobs Act and guidance available. We continue to gather and evaluate the income tax impact of the Tax Cuts and Jobs Act. The ultimate impact of the Tax Cuts and Jobs Act on our reported results in 2018 and beyond may differ, possibly materially, due to, among other things, changes in interpretations and assumptions we have made, guidance that may be issued, and other actions we may take as a result of the Tax Cuts and Jobs Act.

NOTE 8—Commodity Derivative Activities

We use commodity and financial derivative contracts to manage fluctuations in commodity prices. We are currently not designating our derivative contracts for hedge accounting. All derivative gains and losses are from our oil and natural gas derivative contracts and have been recognized in “Other income (expense)” on our Consolidated Statements of Operations.

The following table summarizes gains and losses we recognized on our oil and natural gas derivatives for the three and nine months ended September 30, 2018 and 2017:

	Three Months Ended September 30,						Nine Months Ended September 30,

Total gain (loss) on commodity derivatives not designated as hedges	$	(237	)	$	(313	)	$	(3,392	)	$	193

Commodity Derivative Activity

We enter into swap contracts, costless collars or other derivative agreements from time to time to manage commodity price risk for a portion of our production. Our policy is that all derivatives are approved by the Hedging Committee of the Board, and reviewed periodically by the Board.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Despite the measures taken by us to attempt to control price risk, we remain subject to price fluctuations for natural gas and crude oil sold in the spot market. Prices received for natural gas sold on the spot market are volatile due primarily to seasonality of demand and other factors beyond our control. Decreases in domestic crude oil and natural gas spot prices will have a material adverse effect on our financial position, results of operations and quantities of reserves recoverable on an economic basis. We routinely exercise our contractual right to net realized gains against realized losses when settling with our financial counterparties. Neither our counterparties nor we require any collateral upon entering into derivative contracts. We were not at risk of losing any fair value amounts had our counterparties been unable to fulfill their obligations as of September 30, 2018.    

As of September 30, 2018, the open positions on our outstanding commodity derivative contracts, all of which were with JPMorgan Chase Bank, N.A. and BP Energy Company, were as follows:

Contract Type	Daily Volume	Total Volume	Fixed Price		Fair Value at September 30, 2018 (In thousands)

Overview

Goodrich Petroleum Corporation (“Goodrich” and, together with its wholly-owned subsidiary, Goodrich Petroleum Company, L.L.C. (the “Subsidiary”), “we,” “our,” or the “Company”) is an independent oil and natural gas company engaged in the exploration, development and production of oil and natural gas on properties primarily in (i) Northwest Louisiana and East Texas, which includes the Haynesville Shale Trend, (ii) Southwest Mississippi and Southeast Louisiana, which includes the Tuscaloosa Marine Shale Trend (“TMS”), and (iii) South Texas, which includes the Eagle Ford Shale Trend.

We seek to increase shareholder value by growing our oil and natural gas reserves, production, revenues and cash flow from operating activities (“operating cash flow”). In our opinion, on a long term basis, growth in oil and natural gas reserves, cash flow and production on a cost-effective basis are the most important indicators of performance success for an independent oil and natural gas company.

We strive to increase our oil and natural gas reserves, production and cash flow through exploration and development activities. We develop an annual capital expenditure budget, which is reviewed and approved by our Board of Directors (the “Board”) on a quarterly basis and revised throughout the year as circumstances warrant. We take into consideration our projected operating cash flow, commodity prices for oil and natural gas and available sources of external financing, such as bank debt, asset divestitures, issuances of debt and equity securities, and strategic joint ventures, when establishing our capital expenditure budget.

We place primary emphasis on our operating cash flow in managing our business. Management considers operating cash flow a more important indicator of our financial success than other traditional performance measures, such as net income, because operating cash flow considers only the cash expenses incurred during the period and excludes the non-cash impact of derivative gains (losses) on derivatives not yet settled, non-cash general and administrative expenses and impairments.

Our revenues and operating cash flow depend on the successful development of our inventory of capital projects with available capital, the volume and timing of our production, as well as prevailing commodity prices for oil and natural gas. Commodity prices are largely beyond our control; however, we employ commodity hedging techniques in an attempt to minimize the volatility of short term commodity price fluctuations on our revenues and operating cash flow.

Primary Operating Areas

Haynesville Shale Trend

Our development acreage in the Haynesville Shale Trend is primarily centered in DeSoto, Caddo and Red River parishes, Louisiana. We held approximately 46,400 gross (22,400 net) acres as of September 30, 2018 producing from and prospective for the Haynesville Shale Trend. Our net production volumes from our Haynesville Shale Trend wells represented approximately 96% of our total equivalent production on a Mcfe basis for the third quarter of 2018. We completed and produced 7 gross (3.0 net) new wells in the third quarter of 2018 and have 5 gross (3.4 net) wells in the drilling and completion phases as of September 30, 2018. We plan to focus all of our remaining 2018 drilling efforts in the Haynesville Shale Trend.

Tuscaloosa Marine Shale Trend

We held approximately 55,500 gross (39,300 net) acres in the TMS as of September 30, 2018. We have 2 gross (1.7 net) TMS wells drilled and awaiting completion. Our net production volumes from our TMS wells represented approximately 4% of our total equivalent production on a Mcfe basis and approximately 100% of our total oil production for the third quarter of 2018. Despite making no capital expenditures, we are seeking to maintain production through strategic expense workover operations in the TMS.

Eagle Ford Shale Trend

We hold approximately 12,300 net acres of undeveloped leasehold in the Eagle Ford Shale Trend all of which is prospective for future development or sale.

21

Results of Operations

The Company recorded net income of $1.7 million for the three months ended September 30, 2018 and a net loss of $6.3 million for nine months ended September 30, 2018. The items that had the most material financial effect on our net loss of $6.3 million for the nine months ended September 30, 2018 were a $3.4 million loss on our commodity derivatives not designated as hedges, $4.7 million share-based compensation included in general and administrative expense and $8.5 million in interest expense. All but $1.3 million of these items are non-cash expenses.

The Company recorded net income of $0.7 million for the three months ended September 30, 2017 and a net loss of $6.2 million for the nine months ended September 30, 2017. The items that had the most material financial effect on our net loss of $6.2 million for the nine months ended September 30, 2017 were lease operating expense and $3.0 million in shared-based compensation included in general and administrative expense. Lease operating expense in the period included $3.1 million in workover expenses incurred in our effort to increase production volumes after having curtailed such expenditures while in bankruptcy during the previous year.

The following table reflects our summary operating information for the periods presented (in thousands, except for price and volume data). Because of normal production declines, increased or decreased drilling activity and the effects of acquisitions or divestitures, the historical information presented below should not be interpreted as indicative of future results.

Natural gas, oil and condensate revenues increased by $11.4 million and $19.5 million for the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017. The increase was primarily driven by higher natural gas production and higher realized oil prices offset by lower oil production and lower natural gas prices. The increase in natural gas production volumes is attributed to seven Haynesville Shale Trend wells completed in the third quarter of 2018 and the continued production of nine Haynesville Shale Trend wells completed in 2017 and the first half of 2018. We are concentrating our operational activities and resources on increasing natural gas production in the Haynesville Shale Trend. For the three and nine months ended September 30, 2018, 85% and 78%, respectively, of our oil and natural gas revenue was attributable to natural gas sales compared to 74% and 67% for the three and nine months ended September 30, 2017, respectively.

Operating Expenses

As described below, total operating expenses increased $8.4 million and $12.3 million for the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017. The increase in total operating expenses for the three months ended September 30, 2018 was primarily due to increased depreciation, depletion and amortization expense of

22

$4.4 million, increased transportation and processing expense of $1.7 million, increased production and other taxes of $1.0 million and increased general and administrative expense of $0.9 million. The increase in total operating expenses for the nine months ended September 30, 2018 was primarily due to increased depreciation, depletion and amortization expense of $8.0 million, increased general and administrative expense of $2.7 million, increased transportation expense of $2.1 million and increased production and other taxes of $1.2 million, offset by decreased lease operating expense of $1.8 million.

	Three Months Ended September 30,										Nine Months Ended September 30,

Production and other taxes	$	0.12	$	—		$	0.12		100	%	$	0.14	$	0.12	$	0.02		17	%

Lease Operating Expense

Lease operating expense increased $0.4 million during the three months ended September 30, 2018 and decreased $1.8 million during the nine months ended September 30, 2018 compared to the same periods in 2017. The increase for the three months ended September 30, 2018 versus the same period in the prior year is due to increased costs from an increased well count in 2018. The decrease for the nine months ended September 30, 2018 is substantially attributed to a decrease in workover expense and lower per unit costs for new Haynesville Shale Trend wells compared to the same period in 2017, offset by increased costs due to an increased well count for the nine months ended September 30, 2018. We incurred $3.1 million in workover cost for the nine months ended September 30, 2017 and only $1.0 million for the nine months ended September 30, 2018. The majority of the workover expense incurred in the third quarter of 2018 is attributed to our TMS wells in the effort to maintain our oil production. Lease operating expense exclusive of workover expense on a per unit basis was $0.29 and $0.55 per Mcfe for the three months ended September 30, 2018 and 2017, respectively, and $0.40 and $0.69 for the nine months ended September 30, 2018 and 2017, respectively. We expect per unit lease operating expense to continue to decrease as we increase production from the Haynesville Shale Trend, which carries a lower per unit lease operating expense than the Company’s current per unit rate.

Production and Other Taxes

Production and other taxes, which includes severance and ad valorem taxes, has increased by $1.0 million and $1.2 million for the three and nine months ended September 30, 2018, respectively, as compared to the same periods in 2017.

Severance taxes for the three and nine months ended September 30, 2018 were $0.8 million and $1.5 million, respectively, compared to $0.1 million and $0.9 million, respectively, in the same periods in 2017. The three and nine month periods ended September 30, 2017 were impacted by a non-recurring reduction of $0.3 million mostly related to tight gas sands tax refunds from the State of Texas. The three and nine month periods ended September 30, 2018 reflects the impact of a non-recurring $0.2 million true up related to take-in-kind gas volumes and an increase of approximately $0.2 million related to the expiration of severance tax exemptions and the State of Louisiana having increased the severance tax rate by 10% on July 1, 2018.

The State of Mississippi has enacted an exemption from the existing 6.0% severance tax for horizontal wells drilled after July 1, 2013 with production commencing before July 1, 2018, which is partially offset by a 1.3% local severance tax on such wells. The tax exemption on all of our Mississippi oil wells has expired.

The State of Louisiana has also enacted an exemption from the existing 12.5% severance tax on oil and from the $0.098 per Mcf (through June 30, 2017), $0.111 per Mcf (from July 1, 2017 through June 30, 2018) and $0.122 per Mcf (starting on July 1, 2018) severance tax on natural gas for horizontal wells with production commencing after July 31, 1994. The exemption is applicable until the earlier of (i) 24 months from the date of first sale of production or (ii) payout of the well. Our recently drilled Haynesville Shale Trend natural gas wells in Northwest Louisiana are benefiting from this exemption. The tax exemption on all our Louisiana oil wells has expired.

Ad valorem taxes for the three and nine months ended September 30, 2018 were $0.2 million and $0.7 million, respectively, compared to a negative $0.1 million and $0.2 million, respectively, in the same periods in 2017. The increase in ad valorem tax between periods reflects refunds or tax credits received of $0.2 million and $0.5 million for the three and nine months ended September 30, 2017, respectively, while no refunds were received in the same periods in 2018.

Transportation and Processing

Transportation and processing expense for the three and nine months ended September 30, 2018 increased while per unit expense decreased compared to the same periods in 2017, reflecting increased production from our operated Haynesville Shale Trend wells. Our natural gas volumes from our operated wells generally carry less transportation cost than from wells we do not operate. Our per unit transportation cost will continue to decrease as we increase our operated natural gas production.

Depreciation, Depletion and Amortization (“DD&A”)

DD&A expense is calculated on the Full Cost Method of Accounting using the units of production (the “UOP”) method. The increase in DD&A was attributed primarily to increased production for the three and nine months ended September 30, 2018 as compared to the same periods in 2017.

General and Administrative (“G&A”)

We recorded $4.6 million and $14.6 million in G&A expense for the three and nine months ended September 30, 2018, respectively, which included non-cash expenses of $1.5 million and $4.6 million, respectively, for share based compensation. G&A expense increased for the three and nine months ended September 30, 2018 by $0.9 million and $2.7 million, respectively, compared to the same periods in 2017 primarily due to increased share based compensation expense and other employee related expenses including employee benefits costs and accrued performance bonuses.

We recorded $3.7 million and $12.0 million in G&A expense in the three and nine months ended September 30, 2017, respectively, which included non-cash expenses of (i) $1.0 million and $3.0 million, respectively, for share based compensation, (ii) $0.7 million and $2.1 million, respectively, in performance bonuses of which a majority were compensated in common stock and (iii) $0.1 million and $0.4 million, respectively, of office rent amortization.

Other Operating Expense

We recorded $0.1 million in Other operating expense for the nine months ended September 30, 2018, which includes a $0.2 million loss on the sale of inventory offset by gains recorded on material transfers.

Interest Expense

Interest expense for the three and nine months ended September 30, 2018 reflected cash interest of $0.3 million and $0.5 million, respectively, incurred on the 2017 Senior Credit Facility (as defined below) and non-cash interest of $2.8 million and $8.0 million, respectively, incurred on the Company's 13.50% Convertible Second Lien Senior Secured Notes due 2019 (the “Convertible Second Lien Notes”), which included $1.7 million and $4.9 million, respectively, of paid in-kind interest and $1.1 million and $2.9 million, respectively, of amortization of debt discount.

Interest expense for the three and nine months ended September 30, 2017 reflected cash interest of $0.4 million and $0.9 million, respectively, incurred on the Exit Credit Facility and non-cash interest of $2.2 million and $6.2 million, respectively, incurred on the Convertible Second Lien Notes, which included the paid in-kind interest and amortization of debt discount.

Gain (Loss) on Commodity Derivatives Not Designated as Hedges

Loss on commodity derivatives not designated as hedges for the three and nine months ended September 30, 2018 was comprised of a loss on unsettled derivatives of less than $0.1 million and $2.7 million, respectively, representing the change of the fair value of our open natural gas and oil derivative contracts, as well as a loss of $0.2 million and $0.7 million, respectively, on cash settlement of natural gas and oil derivative contracts.

Gain (loss) on commodity derivatives not designated as hedges for the three and nine months ended September 30, 2017 was comprised of a loss on unsettled derivatives of $0.5 million and $0.1 million, respectively, representing the change of the fair value of our open natural gas derivative contracts, offset by gains of $0.2 million and $0.3 million, respectively, on cash settlement of natural gas and oil derivative contracts.

Reorganization gain (loss), net

Reorganization gain (loss), net for the three and nine months ended September 30, 2018 was less than $0.1 million loss and a $0.3 million loss, respectively. The final expenses related to reorganization were incurred in the third quarter of 2018 for less than $0.1 million. The claims settled in 2018, offset by the legal and trustee fees incurred, resulted in a net reorganization loss of $0.3 million for the nine months ended September 30, 2018. We settled all remaining claims and closed our bankruptcy case in the third quarter of 2018. We anticipate distributing the remaining approximately 39 thousand shares of common stock and related warrants that were granted to the predecessor company's unsecured creditors per the Plan of Reorganization in the fourth quarter of 2018.

Income Tax Benefit

We recorded no income tax expense or benefit for the three or nine months ended September 30, 2018 or 2017. We recorded a valuation allowance for our net deferred tax asset at December 31, 2016. The valuation allowance was $86.7 million at December 31, 2017, which resulted in a net non-current deferred tax asset of $0.9 million appearing on our statement of financial position. We recorded this valuation allowance at this date after an evaluation of all available evidence (including our recent history of net operating losses in 2017 and prior years) that led to a conclusion that based upon the more-likely-than-not standard of the accounting literature, these deferred tax assets were unrecoverable. The tax benefit recorded is due to Alternative Minimum Tax (“AMT”) credits that are expected to be recognized by the Company, which have been reduced for the anticipated sequestration. During the three months ended September 30, 2018, the Company estimated it would receive $0.2 million in AMT credits in 2018 and therefore setup an accounts receivable balance for that amount. The remaining $0.7 million of AMT credits, which is less anticipated sequestration, remain recorded as a deferred tax asset and are expected to be fully refundable in tax years 2019 - 2021 regardless of the Company's regular tax liability as a result of the repeal of the Corporate AMT under the Tax Cuts and Jobs Act. The Company no longer has a valuation allowance recorded against our estimate of refundable AMT credits. Considering the Company’s taxable income forecasts, our assessment of the realization of our deferred tax assets has not changed, and we continue to maintain a full valuation allowance for our net deferred tax assets as of September 30, 2018 aside from the deferred tax asset related to the AMT credits.

Adjusted EBITDA

Adjusted EBITDA is a supplemental non-United States Generally Accepted Accounting Principle (“US GAAP”) financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDA as earnings before interest expense, income tax, DD&A, share based compensation expense and impairment of oil and natural gas properties. In calculating

25

Adjusted EBITDA, mark-to-market gains/losses on commodity derivatives not designated as hedges are also excluded. Other excluded items include interest income, reorganization and other non-recurring non-cash income and expense. Adjusted EBITDA is not a measure of net income (loss) as determined by US GAAP. Adjusted EBITDA should not be considered an alternative to net income (loss), as defined by US GAAP. The following table presents a reconciliation of the non-US GAAP measure of Adjusted EBITDA to the US GAAP measure of net income (loss), its most directly comparable measure presented in accordance with US GAAP:

	Three Months Ended September 30,						Nine Months Ended September 30,
(In thousands)	2018			2017			2018			2017
Net income (loss) (US GAAP)	$	1,666		$	720		$	(6,319	)	$	(6,219	)
Interest expense	3,105			2,529			8,510			7,068
Depreciation, depletion and amortization	7,922			3,516			16,934			8,893
Share based compensation expense (non-cash)	1,597			1,715			4,763			5,093
Mark-to-market loss on commodity derivatives not designated as hedges	41			479			2,655			120
Other items (1)	(45		)	(1,358		)	54			(1,574		)
Adjusted EBITDA	$	14,286		$	7,601		$	26,597		$	13,381

(1) Other items include interest income, reorganization and other non-recurring non-cash income and expense.

Management believes that this non-US GAAP financial measure provides useful information to investors because it is monitored and used by our management and widely used by professional research analysts in the valuation and investment recommendations of companies within the oil and natural gas exploration and production industry. Our computations of Adjusted EBITDA/EBITDAX are defined in our 2017 Senior Credit Facility Agreement (for 2018), Exit Credit Facility Agreement (for 2017) and the indenture governing our Convertible Second Lien Notes, consequently it may not be comparable to other similarly totaled measures of other companies.

Liquidity and Capital Resources

Overview

Our primary sources of cash during the three months ended September 30, 2018 were cash on hand, cash from operating activities, and borrowings under our 2017 Senior Credit Facility. We used cash primarily to fund capital expenditures. We currently plan to fund our operations and capital expenditures for the remainder of 2018 through a combination of cash on hand, cash from operating activities and borrowings under our 2017 Senior Credit Facility, although we may from time to time consider the funding alternatives described below.

On October 17, 2017, we entered into the Amended and Restated Senior Secured Revolving Credit Facility (“Credit Agreement”) with the Subsidiary, as borrower, JPMorgan Chase Bank, N.A. as administrative agent, and certain lenders that are party thereto, which provides for revolving loans of up to the borrowing base then in effect (the “2017 Senior Credit Facility”). Total lender commitments under the 2017 Senior Credit Facility are $250.0 million. The 2017 Senior Credit Facility matures on (a) October 17, 2021 or (b) if the Convertible Second Lien Notes have not been voluntarily redeemed, repurchased, refinanced or otherwise retired by December 30, 2019, then December 30, 2019. Revolving borrowings under the 2017 Senior Credit Facility are limited to, and subject to periodic redeterminations of, the borrowing base. The initial borrowing base was $40 million, and the current borrowing base is $75.0 million with a $50.0 million draw limit. Pursuant to the terms of the 2017 Senior Credit Facility, borrowing base redeterminations will be on a semi-annual basis on or about March 1st and September 1st of each calendar year. JPMorgan Chase Bank, N.A. is the lead lender and administrative agent under the 2017 Senior Credit Facility.

We exited the third quarter of 2018 with cash of $1.9 million and $15.0 million of outstanding borrowings with $35.0 million of availability under the 2017 Senior Credit Facility. Effective October 15, 2018, our borrowing base was increased to $75.0 million with an elected draw limit of $50.0 million in recognition of the limitation set forth in the Convertible Second Lien Notes. This increase in our borrowing base constituted the scheduled redetermination for fall 2018 under the 2017 Senior Credit Facility. Our heavily weighted capital expenditures in the third quarter of 2018 resulted in a working capital deficit of $37.5 million as of September 30, 2018, which was not totally offset by the liquidity available under the 2017 Senior Credit Facility. Our plan is to decrease the current working capital deficit in the fourth quarter of 2018 by reducing our capital spending and benefiting from the increase in natural gas revenue provided by our third quarter 2018 capital expenditures. We

26

expect our working capital deficit as of December 31, 2018 to be more than offset by the liquidity available under the 2017 Senior Credit Facility.

Our total annual capital expenditures through September 30, 2018 were $90.3 million, and our capital expenditure plan for 2018 is expected to range between $98 million to $100 million. We have focused all of our 2018 drilling efforts in the Haynesville Shale Trend and plan to focus our remaining 2018 drilling efforts in the Haynesville Shale Trend.

We continuously monitor our leverage position and coordinate our capital program with our expected cash flows and repayment of our projected debt. We will continue to evaluate funding alternatives as needed.

Alternatives available to us include:

• sale of non-core assets;

• joint venture partnerships in our TMS, Eagle Ford Shale Trend, and/or core Haynesville Shale Trend acreage; and

• issuance of debt or equity securities.

We have supported our cash flows with derivative contracts that covered approximately 47% and 38% of our natural gas sales volumes for the three and nine months ended September 30, 2018, respectively, and 62% of our oil sales volumes for the three and nine months ended September 30, 2017. For additional information on our derivative instruments see Note 8—“Commodity Derivative Activities” in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

Cash Flows

The following table presents our comparative cash flow summary for the periods reported (in thousands):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2018			2017			2018			2017

Operating activities: Production from our wells, the price of oil and natural gas and operating costs represent the main drivers behind our cash flow from operations for both the three and nine months ended September 30, 2018 and 2017. Changes in working capital and net cash settlements related to our derivative contracts also impact cash flows. Net cash provided by operating activities for the three months ended September 30, 2018 was $24.1 million including operating cash flows before working capital changes of $13.8 million reduced by net cash payments of $0.2 million in settlement of derivative contracts. Net cash provided by operating activities for the three months ended September 30, 2017 was $0.3 million including operating cash flows before working capital changes of $8.3 million including net cash receipts of $0.2 million in settlement of derivatives. Net cash provided by operating activities for the nine months ended September 30, 2018 was $36.7 million including operating cash flows before working capital changes of $26.3 million reduced by net cash payments of $0.7 million in settlement of derivative contracts. Net cash provided by operating activities for the nine months ended September 30, 2017 was $16.4 million including operating cash flows before working capital changes of $13.6 million including net cash receipts of $0.3 million in settlement of derivatives.

Investing activities: Net cash used in investing activities was $32.0 million for the three months ended September 30, 2018. We recorded $38.3 million in capital expenditures in the period reflecting a net $4.3 million increase in the capital expenditure accrual and $2.0 million of other non-cash additions which include draws from materials inventory and non-cash internal cost. We conducted drilling operations on 12 gross (6 net) wells and completed 7 gross (3 net) wells all in the Haynesville Shale Trend during the three months ended September 30, 2018.

Net cash used in investing activities was $58.2 million for the nine months ended September 30, 2018 which reflects cash expended on capital projects of $85.1 million reduced by $26.9 million cash proceeds received from sales of oil and gas properties. We recorded $90.3 million in capital expenditures in the period, reflecting a net increase of the capital expenditure accrual of $1.5 million, utilized $1.7 million from materials inventory, utilized $1.2 million cash calls paid in previous periods,

27

recorded non-cash internal cost of $0.6 million and capitalized retirement obligations of $0.2 million. We conducted drilling operations on 19 gross (10 net) wells and completed 14 gross (7 net) wells all in the Haynesville Shale Trend during the nine months ended September 30, 2018.

Financing activities: Net cash provided by financing activities for the three months ended September 30, 2018 primarily reflects the borrowings under our 2017 Senior Credit Facility. Net cash used in financing activities for the nine months ended September 30, 2018 reflects the $1.8 million net repayment of costs incurred under our 2017 Senior Credit Facility as well as $0.8 million for the purchase of shares withheld from employees stock awards for the payment of taxes.

(1) The debt discount is being amortized using the effective interest rate method based upon a maturity date of August 30, 2019. The principal includes $11.9 million and $7.0 million of paid in-kind interest at September 30, 2018 and December 31, 2017, respectively. The carrying value includes $5.1 million and $8.0 million of unamortized debt discount at September 30, 2018 and December 31, 2017, respectively.

For additional information on our financing activities, see Note 4—“Debt” in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

Off-Balance Sheet Arrangements

We do not currently have any off-balance sheet arrangements for any purpose.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on consolidated financial statements, which were prepared in accordance with US GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We believe that certain accounting policies affect the more significant judgments and estimates used in the preparation of our consolidated financial statements. Our Annual Report on Form 10-K for the year ended December 31, 2017, includes a discussion of our critical accounting policies and there have been no material changes to such policies during the three months ended September 30, 2018.

Item 3—Quantitative and Qualitative Disclosures about Market Risk

Our primary market risks are attributable to fluctuations in commodity prices and interest rates. These fluctuations can affect revenues and cash flow from operating, investing and financing activities. Our risk-management policies provide for the use of derivative instruments to manage these risks. The types of derivative instruments we utilize include futures, swaps, options and fixed-price physical-delivery contracts. The volume of commodity derivative instruments we utilize may vary from year to year and is governed by risk-management policies with levels of authority delegated by our Board. Both exchange and over-the-counter traded commodity derivative instruments may be subject to margin deposit requirements, and we may be required from time to time to deposit cash or provide letters of credit with exchange brokers or its counterparties in order to satisfy these margin requirements.

For information regarding our accounting policies and additional information related to our derivative and financial instruments, see Note 1—“Description of Business and Significant Accounting Policies”, Note 4—“Debt”and Note 8—“Commodity Derivative Activities” in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Quarterly Report on Form 10-Q.

Commodity Price Risk

Our most significant market risk relates to fluctuations in crude oil and natural gas prices. Management expects the prices of these commodities to remain volatile and unpredictable. As these prices decline or rise significantly, revenues and cash flow will also decline or rise significantly. In addition, a non-cash write-down of our oil and natural gas properties may be required if future commodity prices experience a sustained and significant decline. We do not enter into derivatives instruments for trading purposes. Utilizing actual derivative contractual volumes, a hypothetical increase of 10% in the underlying commodity prices would have changed the derivative gas net asset position to a liability position with a change of $6.1 million and increased the derivative oil liability position by $1.0 million as of September 30, 2018. Likewise, a hypothetical decrease of 10% in the underlying commodity prices would have increased the derivative gas net asset position by $6.3 million and decreased the derivative oil liability position by $1.0 million as of September 30, 2018. Furthermore, a gain or loss on derivatives would have been substantially offset by a decrease or increase, respectively, in the actual sales value of production covered by the derivative instruments.

Adoption of Comprehensive Financial Reform

The adoption of comprehensive financial reform legislation by the United States Congress could have an adverse effect on our ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with our business. See Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Item 4—Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures designed to ensure that material information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the Securities and Exchange Commission and that any material information relating to us is recorded, processed, summarized and reported to our management including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating our disclosure controls and procedures, our management recognizes that controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving desired control objectives. In reaching a reasonable level of assurance, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) under the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Our Chief Executive Officer and Chief Financial Officer, based upon their evaluation as of September 30, 2018, the end of the period covered in this report, concluded that our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1—Legal Proceedings

A discussion of our current legal proceedings is set forth in Part I, Item 1 under Note 9—“Commitments and Contingencies” to the Notes to Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

As of September 30, 2018, we did not have any material outstanding and pending litigation.

28

Item 1A—Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2017, which could materially affect our business, financial condition or future results. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially affect our business, financial condition or future results.

Execution Version

SECOND AMENDMENT TO CREDIT AGREEMENT

THIS SECOND AMENDMENT TO CREDIT AGREEMENT (this “Amendment”) is entered into as of October 15, 2018 (the “Second Amendment Execution Date”) to be effective as of September 30, 2018 (the “Second Amendment Effective Date”), by and among GOODRICH PETROLEUM CORPORATION (“Parent”), GOODRICH PETROLEUM COMPANY, L.L.C. (the “Borrower”), JPMORGAN CHASE BANK, N.A., as Administrative Agent, and the Lenders party hereto.

RECITALS:

WHEREAS, reference is made to the Amended and Restated Senior Secured Revolving Credit Agreement dated as of October 17, 2017 (as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), among Parent, the Borrower, each lender from time to time party thereto and JPMorgan Chase Bank, N.A., as the Administrative Agent; and

WHEREAS, the Borrower has requested that the Lenders agree to amend certain provisions of the Credit Agreement, and the Lenders have agreed to amend the Credit Agreement as hereinafter set forth.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Section 1.Defined Terms. Capitalized terms used but not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement, as amended hereby.

Section 2.Amendments to Credit Agreement.

(a)The following definition in Section 1.02 of the Credit Agreement is hereby restated in its entirety to read as follows:

“Maturity Date” means (a) October 17, 2021 or (b) if the 2019 Notes have not been voluntarily redeemed, repurchased, refinanced or otherwise retired by December 30, 2019, December 30, 2019.

(b)Section 9.01(b) of the Credit Agreement is hereby amended and restated to read as follows:

(b)    Current Ratio. Parent and the Borrower will not, as of the last day of any Fiscal Quarter, commencing with the quarter ending December 31, 2018, permit the Current Ratio of Parent and its Consolidated Subsidiaries as of such day to be less than 1.00 to 1.00.

(c)Section 9.21(c) of the Credit Agreement is hereby amended by replacing the word “six” with the word “three”.

Section 3.Borrowing Base Redetermination. Effective as of the Second Amendment Effective Date and pursuant to Section 2.07(c), the Lenders agree that the existing Borrowing Base of $60,000,000 has been redetermined and, as a result thereof, the Borrowing Base shall be increased to $75,000,000 until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment in the Borrowing Base pursuant to the Borrowing Base Adjustment Provisions, whichever occurs first. This redetermination of the Borrowing Base is the result of the Scheduled Redetermination of the Borrowing Base pursuant to Section 2.07(c) that is contemplated by the Credit Agreement to occur on or about September 1, 2018. This paragraph of this Section 3 constitutes the New Borrowing Base Notice with respect to such Scheduled Redetermination.

The Borrower hereby notifies the Administrative Agent and the Lenders that, for the period from the Second Amendment Effective Date until the next succeeding Scheduled Redetermination Date, the Borrower elects a Draw Limit of $50,000,000. The Administrative Agent and the Lenders hereby consent to such Draw Limit and, pursuant to Section 2.07(e) of the Credit Agreement, such amount shall be the new Borrowing Base.

Section 4.Second Amendment Effective Date; Conditions Precedent. This Amendment shall become effective as of the Second Amendment Effective Date upon the satisfaction or waiver of the following conditions:

(a)the Administrative Agent shall have received a counterpart of this Amendment executed by the Borrower, the Administrative Agent and each of the Lenders;

(b)the Borrower shall have paid, to the extent invoiced at or before 12:00 noon, Houston time, on the Business Day immediately prior to the Second Amendment Execution Date, all out‑of‑pocket expenses required to be reimbursed or paid by the Borrower pursuant to Section 12.03 of the Credit Agreement or any other Loan Document; and

(c)the representations and warranties contained in Section 5 hereof shall be true and correct.

The Administrative Agent shall notify the Borrower and the Lenders of the Second Amendment Effective Date and the Second Amendment Execution Date, and such notice shall be conclusive and binding.

Section 5.Representations and Warranties. To induce the other parties hereto to enter into this Amendment, each of Parent and the Borrower represents and warrants that, immediately before and after the effectiveness of this Amendment, (i) all of the representations and warranties contained in each Loan Document to which it is a party are true and correct in all material respects (unless already qualified by materiality in which case such applicable representation and warranty shall be true and correct), except to the extent any such representations and warranties are expressly limited to an earlier date, in which case, such representations and warranties shall continue to be true and correct in all material respects as of such specified earlier date and (ii) no Default or Event of Default has occurred and is continuing.

Section 6.Confirmation of Loan Documents. Except as expressly contemplated hereby, the terms, provisions, conditions and covenants of the Credit Agreement, as amended by this Amendment, and the other Loan Documents remain in full force and effect and are hereby ratified and confirmed, and the execution, delivery and performance of this Amendment shall not, except as expressly set forth in this Amendment, operate as a waiver of, consent to or amendment of any term, provision, condition or covenant thereof.

Accounting Policies [Abstract]

Description of Business and Significant Accounting Policies

Description of Business and Significant Accounting Policies

Goodrich Petroleum Corporation (“Goodrich” and, together with its wholly-owned subsidiary, Goodrich Petroleum Company, L.L.C. (the “Subsidiary”), “we,” “our,” or the “Company”) is an independent oil and natural gas company engaged in the exploration, development and production of oil and natural gas on properties primarily in (i) Northwest Louisiana and East Texas, which includes the Haynesville Shale Trend, (ii) Southwest Mississippi and Southeast Louisiana, which includes the Tuscaloosa Marine Shale Trend (“TMS”), and (iii) South Texas, which includes the Eagle Ford Shale Trend.

Basis of Presentation

The consolidated financial statements of the Company included in this Quarterly Report on Form 10-Q have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and accordingly, certain information normally included in financial statements prepared in accordance with United States Generally Accepted Accounting Principles (“US GAAP”) has been condensed or omitted. This information should be read in conjunction with our consolidated financial statements and notes contained in our annual report on Form 10-K for the year ended December 31, 2017. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the full year or for any interim period.

Principles of Consolidation—The consolidated financial statements include the financial statements of Goodrich and the Subsidiary. Intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements reflect all normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation. Certain data in prior periods’ financial statements have been adjusted to conform to the presentation of the current period. We have evaluated subsequent events through the date of this filing.

Use of Estimates— Our management has made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements in conformity with US GAAP.

Cash and Cash Equivalents—Cash and cash equivalents includes cash on hand, demand deposit accounts and temporary cash investments with maturities of ninety days or less at the date of purchase.

Accounts Payable—Accounts payable consisted of the following amounts as of September 30, 2018 and December 31, 2017:

(In thousands)	September 30, 2018		December 31, 2017
Trade payables	$	15,730	$	4,092
Revenue payable	13,675		10,692
Prepayments from partners	259		2,193
Miscellaneous payables	585		227
Total Accounts payable	$	30,249	$	17,204

Accrued Liabilities—Accrued liabilities consisted of the following amounts as of September 30, 2018 and December 31, 2017:

(In thousands)	September 30, 2018		December 31, 2017
Accrued capital expenditures	$	12,038	$	10,511
Accrued lease operating expense	784		786
Accrued production and other taxes	1,069		449
Accrued transportation and gathering	1,417		1,130
Accrued performance bonus	2,808		3,869
Accrued interest	284		244
Accrued office lease	622		696
Accrued reorganization costs	—		168
Accrued general and administrative expense and other	601		222
Total Accrued liabilities	$	19,623	$	18,075

Inventory –Inventory consists of casing and tubulars that are expected to be used in our capital drilling program. Inventory is carried on the Consolidated Balance Sheets at the lower of cost or market.

Property and Equipment—Under US GAAP, two acceptable methods of accounting for oil and natural gas properties are allowed. These are the Successful Efforts Method and the Full Cost Method. Entities engaged in the production of oil and natural gas have the option of selecting either method for application in the accounting for their properties. The principal differences between the two methods are in the treatment of exploration costs, the computation of Depreciation, Depletion and Amortization (“DD&A”) expense and the assessment of impairment of oil and natural gas properties. We use the Full Cost Method to account for our investment in oil and gas properties.

Under the Full Cost Method, we capitalize all costs associated with acquisitions, exploration, development and estimated abandonment costs. We capitalize internal costs that can be directly identified with the acquisition of leasehold, as well as drilling and completion activities, but do not include any costs related to production, general corporate overhead or similar activities. Unevaluated property costs are excluded from the amortization base until we make a determination as to the existence of proved reserves on the respective property or impairment. We review our unevaluated properties at the end of each quarter to determine whether the costs should be reclassified to proved oil and natural gas properties and thereby subject to DD&A and the full cost ceiling test. For the three months ended September 30, 2018 and 2017, we transferred $5.7 million and $5.8 million, respectively, from unevaluated properties to proved oil and natural gas properties. For the nine months ended September 30, 2018 and 2017, we transferred $6.1 million and $18.6 million, respectively, from unevaluated properties to proved oil and natural gas properties. Our sales of oil and natural gas properties are accounted for as adjustments to net proved oil and natural gas properties with no gain or loss recognized, unless the adjustment would significantly alter the relationship between capitalized costs and proved reserves.

We amortize our investment in oil and natural gas properties through DD&A expense using the units of production (the “UOP”) method. An amortization rate is calculated based on total proved reserves converted to equivalent thousand cubic feet of natural gas (“Mcfe”) as the denominator and the net book value of evaluated oil and gas asset together with the estimated future development cost of the proved undeveloped reserves as the numerator. The rate calculated per Mcfe is applied against the periods' production also converted to Mcfe to arrive at the periods' DD&A expense.

Depreciation of furniture, fixtures and equipment, consisting of office furniture, computer hardware and software and leasehold improvements, is computed using the straight-line method over their estimated useful lives, which vary from three to five years.

Full Cost Ceiling Test—The Full Cost Method requires that at the conclusion of each financial reporting period, the present value of estimated future net cash flows from proved reserves (adjusted for hedges and excluding cash flows related to estimated abandonment costs), be compared to the net capitalized costs of proved oil and natural gas properties, net of related deferred taxes. This comparison is referred to as a "ceiling test". If the net capitalized costs of proved oil and natural gas properties exceed the estimated discounted future net cash flows from proved reserves, we are required to write-down the value of our oil and natural gas properties to the value of the discounted cash flows. Estimated future net cash flows from proved reserves are calculated based on a 12-month average pricing assumption.

There were no Full Cost Ceiling Test write-downs for the three or nine months ended September 30, 2018 or 2017.

Fair Value Measurement—Fair value is defined as the price 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. The fair value of an asset should reflect its highest and best use by market participants, whether in-use or an in-exchange valuation premise. The fair value of a liability should reflect the risk of non-performance, which includes, among other things, our credit risk.

We use various methods, including the income approach and market approach, to determine the fair values of our financial instruments that are measured at fair value on a recurring basis, which depend on a number of factors, including the availability of observable market data over the contractual term of the underlying instrument. For some of our instruments, the fair value is calculated based on directly observable market data or data available for similar instruments in similar markets. For other instruments, the fair value may be calculated based on these inputs as well as other assumptions related to estimates of future settlements of these instruments. We separate our financial instruments into three Levels (Levels 1, 2 and 3) based on our assessment of the availability of observable market data and the significance of non-observable data used to determine the fair value of our instruments. Our assessment of an instrument can change over time based on the maturity or liquidity of the instrument, which could result in a change in the classification of the instruments between Levels.

Each of these Levels and our corresponding instruments classified by Level are further described below:

• Level 1 Inputs— unadjusted quoted market prices in active markets for identical assets or liabilities. We have no Level 1 instruments;

• Level 2 Inputs— quotes that are derived principally from or corroborated by observable market data. Included in this Level are our 2017 Senior Credit Facility and commodity derivatives whose fair values are based on third-party quotes or available interest rate information and commodity pricing data obtained from third party pricing sources and our creditworthiness or that of our counterparties; and

• Level 3 Inputs— unobservable inputs for the asset or liability, such as discounted cash flow models or valuations, based on our various assumptions and future commodity prices. Included in this Level would be our initial measurement of asset retirement obligations.

As of September 30, 2018 and December 31, 2017, the carrying amounts of our cash and cash equivalents, trade receivables and payables represented fair value because of the short-term nature of these instruments.

Asset Retirement Obligations—Asset retirement obligations are related to the abandonment and site restoration requirements that result from the exploration and development of our oil and natural gas properties. We record the fair value of a liability for an asset retirement obligation in the period in which it is incurred and a corresponding increase in the carrying amount of the related long-lived asset. Accretion expense is included in “Depreciation, depletion and amortization” on our Consolidated Statements of Operations. See Note 3.

The estimated fair value of the Company’s asset retirement obligations at inception is determined by utilizing the income approach by applying a credit-adjusted risk-free rate, which takes into account the Company’s credit risk, the time value of money, and the current economic state, to the undiscounted expected abandonment cash flows. Given the unobservable nature of the inputs, the initial measurement of the asset retirement obligations was classified as Level 3 in the fair value hierarchy.

Revenue Recognition—Oil and natural gas revenues are recognized upon delivery of our produced oil and natural gas volumes to our customers. Revenues from the production of crude oil and natural gas properties in which we have an interest with other producers are recognized in accordance with when the producing company records revenue on those volumes. We record a liability or an asset for natural gas balancing when we have sold more or less than our working interest share of natural gas production, respectively. AtSeptember 30, 2018and December 31, 2017, the net liability for natural gas balancing was immaterial. Differences between actual production and net working interest volumes are routinely adjusted. See Note 2.

Derivative Instruments—We use derivative instruments such as futures, forwards, options, collars and swaps for purposes of hedging our exposure to fluctuations in the price of crude oil and natural gas and to hedge our exposure to changing interest rates. Accounting standards related to derivative instruments and hedging activities require that all derivative instruments subject to the requirements of those standards be measured at fair value and recognized as assets or liabilities in the balance sheet. We offset the fair value of our asset and liability positions with the same counterparty for each commodity type. Changes in fair value are required to be recognized in earnings unless specific hedge accounting criteria are met. All of our realized gain or losses on our derivative contracts are the result of cash settlements. We have not designated any of our derivative contracts as hedges; accordingly, changes in fair value are reflected in earnings. See Note 8.

Income Taxes—We account for income taxes, as required, under the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

We recognize, as required, the financial statement benefit of an uncertain tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. See Note 7.

Net Income or Net Loss Per Share—Basic income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders for each reporting period by the weighted-average number of common shares outstanding during the period. Diluted income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders for each reporting period by the weighted-average number of common shares outstanding during the period, plus the effects of potentially dilutive restricted stock calculated using the treasury stock method and the potential dilutive effect of the conversion of convertible securities, such as warrants and convertible notes, into shares of our common stock. See Note 6.

Commitments and Contingencies—Liabilities for loss contingencies, including environmental remediation costs, arising from claims, assessments, litigation, fines and penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Recoveries from third parties, when probable of realization, are separately recorded and are not offset against the related environmental liability. See Note 9.

Share-Based Compensation—We account for our share-based transactions using the fair value as of the grant date and recognize compensation expense over the requisite service period.

Guarantee—As of September 30, 2018, Goodrich Petroleum Company LLC, the wholly owned subsidiary of Goodrich Petroleum Corporation, was the Subsidiary Guarantor of our 13.50% Convertible Second Lien Senior Secured notes due 2019 (the “Convertible Second Lien Notes”).

Debt Issuance Cost—The Company records debt issuance costs associated with its Convertible Second Lien Notes as a contra balance to long term debt, net in our Consolidated Balance Sheets, which is amortized straight-line over the life of the Convertible Second Lien Notes. Debt issuance costs associated with our revolving credit facility debt are recorded in other assets in our Consolidated Balance Sheets, which is amortized straight-line over the life of such debt.

New Accounting Pronouncements

On August 28, 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820 including the removal, modification and addition of certain disclosure requirements. For all entities, the amendments in this ASU are effective for fiscal periods beginning after December 15, 2019, including interim periods therein. We are evaluating the expected impact these amendments will have on our consolidated financial statements.

On June 20, 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. For public entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2018. We have not granted or issued share-based payments to nonemployees. We have evaluated the provisions of this ASU and do not expect it to have a material impact on our consolidated financial statements.

On March 13, 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740). The ASU adds seven paragraphs to the Accounting Standards Codification “ASC” 740, Income Taxes, that contain SEC guidance related to Staff Accounting Bulletin 118 (“Income Tax Accounting Implications of the Tax Cuts and Jobs Act”) as a result of the tax legislation passed in 2017 known as the “Tax Cuts and Jobs Act”. Specifically, the staff intended to address situations where the accounting under ASC Topic 740 is incomplete for certain income tax effects of the Tax Cuts and Jobs Act upon issuance of an entity’s financial statements for the reporting period in which the Tax Cuts and Jobs Act was enacted. The Company notes that it has considered the updates to ASC 740 as a result of the Tax Cuts and Jobs Act and has prepared its consolidated financial statements in accordance with the Tax Cuts and Jobs Act. See Note 7 for further discussion.

On August 28, 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU is intended to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this ASU make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP based on the feedback received from preparers, auditors, users, and other stakeholders. For public entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2018. We do not expect this ASU to have a material impact on our consolidated financial statements as we currently mark-to-market all of our derivative positions; however, we are evaluating the impact of this ASU should we choose to utilize hedge accounting in the future.

On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842) and subsequently issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements in July 2018. The key difference between the existing standards and ASU 2016-02 is the requirement for lessees to recognize on their balance sheet all lease contracts with lease terms greater than 12 months, including operating leases. Specifically, lessees are required to recognize on the balance sheet at lease commencement, both (i) a right-of-use asset, representing the lessee’s right to use the leased asset over the term of the lease, and (ii) a lease liability, representing the lessee’s contractual obligation to make lease payments over the term of the lease. For lessees, ASU 2016-02 requires classification of leases as either operating or finance leases, which are similar to the current operating and capital lease classifications. However, the distinction between these two classifications under the ASU does not relate to balance sheet treatment, but relate to treatment and recognition in the statements of income and cash flows. Lessor accounting is largely unchanged from current US GAAP. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, for public entities. Early application is permitted. The Company is carrying out its project plan to guide the implementation of ASU 2016-02, which includes assessing our portfolio of leases, determining a process for ensuring completeness of our repository of active leases, determining financial statement impacts and preparing for disclosure requirements under Topic 842. We have not yet completed our evaluation of the impact the new lease accounting guidance will have on our consolidated financial statements; however, we do expect to recognize right of use assets and lease liabilities for our operating leases with terms longer than 12 months in the Consolidated Balance Sheets upon adoption.

Revenue Recognition and Deferred Revenue [Abstract]

Revenue Recognition

Revenue Recognition

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers, and the series of related ASU's that followed under ASC Topic 606 (collectively, “Topic 606”).Under Topic 606, revenue will generally be recognized upon delivery of our produced oil and natural gas volumes to our customers. Our customer sales contracts include oil and natural gas sales. Under Topic 606, each unit (Mcf or barrel) of commodity product represents a separate performance obligation which is sold at variable prices, determinable on a monthly basis. The pricing provisions of our contracts are primarily tied to a market index with certain adjustments based on factors such as delivery, product quality and prevailing supply and demand conditions in the geographic areas in which we operate. We will allocate the transaction price to each performance obligation and recognize revenue upon delivery of the commodity product when the customer obtains control. Control of our produced natural gas volumes passes to our customers at specific metered points indicated in our natural gas contracts. Similarly, control of our produced oil volumes passes to our customers when the oil is measured either by a trucking oil ticket or by a meter when entering an oil pipeline. The Company has no control over the commodities after those points and the measurement at those points dictates the amount on which the customer's payment is based. Our oil and natural gas revenue streams include volumes burdened by royalty and other joint owner working interests. Our revenues are recorded and presented on our financial statements net of the royalty and other joint owner working interests. Our revenue stream does not include any payments for services or ancillary items other than sale of oil and natural gas.

We record revenue in the month our production is delivered to the purchaser. However, settlement statements and payments for our oil and natural gas sales may not be received for up to 60 days after the date production is delivered, and as a result, we are required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. We record any differences, which historically have not been significant, between the actual amounts ultimately received and the original estimates in the period they become finalized. As of September 30, 2018 and December 31, 2017, receivables from contracts with customers were $9.3 million and $5.0 million, respectively.

Topic 606 will not change our pattern of timing of revenue recognition. We utilized the full retrospective method for adoption of Topic 606, and in accordance with this method our consolidated financial statements for periods prior to January 1, 2018 were not materially affected or revised. We also do not anticipate a material impact on our financial statements on an ongoing basis.

The following tables present our oil and natural gas revenues disaggregated by revenue source and by operated and non-operated properties:

Exit Credit Facility

On October 12, 2016, upon consummation of the plan of reorganization and emergence from bankruptcy, the Company entered into an Exit Credit Agreement (the “Exit Credit Agreement”) with the Subsidiary, as borrower (the “Borrower”), and Wells Fargo Bank, National Association, as administrative agent, and certain other lenders party thereto. Pursuant to the Exit Credit Agreement, the lenders party thereto agreed to provide the Borrower with a $20.0 million senior secured term loan credit facility (the “Exit Credit Facility”). On October 17, 2017, the Exit Credit Facility was paid off in full and replaced with the 2017 Senior Credit Facility described below.

2017 Senior Credit Facility

On October 17, 2017, the Company entered into the Amended and Restated Senior Secured Revolving Credit Agreement (the “Credit Agreement”) with the Subsidiary, as borrower, JP Morgan Chase Bank, N.A. as administrative agent, and certain lenders that are party thereto, which provides for revolving loans of up to the borrowing base then in effect, as amended by a first amendment and a second amendment entered into on October 15, 2018 and effective as of September 30, 2018, which increased the borrowing base to $75.0 million and provided for a minimum current ratio financial covenant beginning with the quarter ending on December 31, 2018 (as so amended, “2017 Senior Credit Facility”). The 2017 Senior Credit Facility amended, restated and refinanced the obligations under the Exit Credit Facility. The 2017 Senior Credit Facility matures (a) October 17, 2021 or (b) if the Convertible Second Lien Notes (as defined below) have not been voluntarily redeemed, repurchased, refinanced or otherwise retired by December 30, 2019, December 30, 2019. The maximum credit amount under the 2017 Senior Credit Facility at September 30, 2018 was $250.0 million with a borrowing base of $75.0 million subject to an elected draw limit of $50.0 million. The borrowing base is scheduled to be redetermined in March and September of each calendar year, and is subject to additional adjustments from time to time, including for asset sales, elimination or reduction of hedge positions and incurrence of other debt. Additionally, each of the Borrower and the administrative agent may request one unscheduled redetermination of the borrowing base between scheduled redeterminations. The amount of the borrowing base is determined by the lenders in their sole discretion and consistent with their oil and gas lending criteria at the time of the relevant redetermination. The Company may also request the issuance of letters of credit under the Credit Agreement in an aggregate amount up to $10.0 million, which reduce the amount of available borrowings under the borrowing base in the amount of such issued and outstanding letters of credit.

All amounts outstanding under the 2017 Senior Credit Facility bear interest at a rate per annum equal to, at the Company's option, either (i) the alternative base rate plus an applicable margin ranging from 1.75% to 2.75%, depending on the percentage of the borrowing base that is utilized, or (ii) adjusted LIBOR plus an applicable margin from 2.75% to 3.75%, depending on the percentage of the borrowing base that is utilized. Undrawn amounts under the 2017 Senior Credit Facility are subject to a 0.50% commitment fee. To the extent that a payment default exists and is continuing, all amounts outstanding under the 2017 Senior Credit Facility will bear interest at 2.00% per annum above the rate and margin otherwise applicable thereto. As of September 30, 2018, the interest rate on the 2017 Senior Credit Facility was 7.25%.

The 2017 Senior Credit Facility also contains certain financial covenants, including (i) the maintenance of a ratio of Total Debt (as defined in the Credit Agreement) to EBITDAX not to exceed 4.00 to 1.00 as of the last day of any fiscal quarter, (ii) in accordance with the second amendment to the Credit Agreement, beginning with the quarter ended December 31, 2018, a current ratio (based on the ratio of current assets to current liabilities) not to be less than 1.00 to 1.00 and (iii) until no Convertible Second Lien Notes remain outstanding, (A) the maintenance of a ratio of Total Proved PV10% attributable to the Company’s and Borrower’s Proved Reserves (as defined in the Credit Agreement) to Total Secured Debt (net of any Unrestricted Cash not to exceed $10.0 million) not to be less than 1.50 to 1.00 and (B) minimum liquidity requirements. See Note 11 Subsequent Events for more information on the second amendment to the Credit Agreement.

The obligations under the Credit Agreement are guaranteed by the Company and are secured by a first lien security interest in substantially all of the assets of the Company and the Subsidiary.

As of September 30, 2018, the Company had $15.0 million outstanding borrowings. The Company also had $0.5 million of unamortized debt issuance costs recorded as of September 30, 2018 related to the 2017 Senior Credit Facility.

As of September 30, 2018, the Company was in compliance with all covenants within the 2017 Senior Credit Facility.

13.50% Convertible Second Lien Senior Secured Notes Due 2019

On October 12, 2016, upon emergence from bankruptcy, the Company and the Subsidiary, entered into a purchase agreement (the “Purchase Agreement”) with each entity identified as a Shenkman Purchaser on Appendix A to the Purchase Agreement (collectively, the “Shenkman Purchasers”), CVC Capital Partners (acting through such of its affiliates to managed funds as it deems appropriate), J.P. Morgan Securities LLC (acting through such of its affiliates or managed funds as it deems appropriate), Franklin Advisers, Inc. (as investment manager on behalf of certain funds and accounts), O’Connor Global Multi-Strategy Alpha Master Limited and Nineteen 77 Global Multi-Strategy Alpha (Levered) Master Limited (collectively, and together with each of their successors and assigns, the “Purchasers”), in connection with the issuance of $40.0 million aggregate principal amount of the Company’s 13.50% Convertible Second Lien Senior Secured Notes due 2019 (the “Convertible Second Lien Notes”).

The aggregate principal amount of the Convertible Second Lien Notes is convertible at the option of the Purchasers at any time prior to the scheduled maturity date at $21.33 per share, subject to adjustments. At closing, the Purchasers were issued 10-year costless warrants to acquire 2.5 million shares of common stock. Holders of the Convertible Second Lien Notes have a second priority lien on all assets of the Company, and have a continuing right to appoint two members to our Board of Directors (the “Board”) as long as the Convertible Second Lien Notes are outstanding.

The Convertible Second Lien Notes as set forth in the agreement, will mature on August 30, 2019 or six months after the maturity of our current revolving credit facility but in no event later than March 30, 2020. The 2017 Senior Credit Facility matures no earlier than December 30, 2019; consequently, the Convertible Second Lien Notes will mature on March 30, 2020. The Convertible Second Lien Notes bear interest at the rate of 13.50% per annum, payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year. The Company may elect to pay all or any portion of interest in-kind on the then outstanding principal amount of the Convertible Second Lien Notes by increasing the principal amount of the outstanding Convertible Second Lien Notes or by issuing additional Second Lien Notes (“PIK Interest Notes”). The PIK Interest Notes are not convertible. During such time as the Exit Credit Agreement (but not any refinancing or replacement thereof) was in effect, interest on the Convertible Second Lien Notes had to be paid in-kind. As to the new 2017 Senior Credit Facility, interest on the Convertible Second Lien Notes must be paid in-kind; provided however, that after the quarter ending March 31, 2018, if (i) there is no default, event of default or borrowing base deficiency that has occurred and is continuing, (ii) the ratio of total debt to EBITDAX as defined under the 2017 Senior Credit Facility is less than 1.75 to 1.0 and (iii) the unused borrowing base is at least 25%, then the Company can pay the interest on the Convertible Second Lien Notes in cash, at its election.

The indenture governing the Convertible Second Lien Notes (the “Indenture”) contains certain covenants pertaining to us and our subsidiary, including delivery of financial reports; environmental matters; conduct of business; use of proceeds; operation and maintenance of properties; collateral and guarantee requirements; indebtedness; liens; dividends and distributions; limits on sale of assets and stock; business activities; transactions with affiliates; and changes of control.

The Indenture also contains certain financial covenants, including the maintenance of (i) a Total Proved Asset Coverage Ratio (as defined in the Exit Credit Agreement) not to be less than 1.50 to 1.00 after September 30, 2017, to be determined as of January 1 and July 1 of each year and (ii) minimum liquidity requirements.

Upon issuance of the Convertible Second Lien Notes in October 2016, in accordance with accounting standards related to convertible debt instruments that may be settled in cash upon conversion as well as warrants on the debt instrument, we recorded a debt discount of $11.0 million, thereby reducing the $40.0 million carrying value upon issuance to $29.0 million and recorded an equity component of $11.0 million. The debt discount is amortized using the effective interest rate method based upon an original term through August 30, 2019. $5.1 million of debt discount remains to be amortized on the Convertible Second Lien Notes as of September 30, 2018.

As of September 30, 2018, the Company was in compliance with all covenants within the Indenture governing the Convertible Second Lien Notes.

During the three months ended September 30, 2018, no holders of the 10 year costless warrants associated with the Convertible Second Lien Notes exercised warrants. During the nine months ended September 30, 2018, certain holders of the 10 year costless warrants associated with the Convertible Second Lien Notes exercised 862,812 warrants for the issuance of an equal amount of our one cent par value common stock. The Company received cash for the one cent par value for the issuance of 315,937 common shares. As of September 30, 2018, 207,500 of such warrants remain un-exercised.

During the three months ended September 30, 2017, certain holders of the 10 year costless warrants associated with the Convertible Second Lien Notes exercised 54,687 warrants for the issuance of an equal amount of our one cent par value common stock. The Company received cash for the one cent par value for issuance of 54,687 common shares.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We recorded no income tax expense or benefit for the three or nine months ended September 30, 2018 or 2017. We recorded a valuation allowance for our net deferred tax asset at December 31, 2016. The valuation allowance was $86.7 million at December 31, 2017, which resulted in a net non-current deferred tax asset of $0.9 million appearing on our statement of financial position. We recorded this valuation allowance at this date after an evaluation of all available evidence (including our recent history of net operating losses in 2017 and prior years) that led to a conclusion that based upon the more-likely-than-not standard of the accounting literature, these deferred tax assets were unrecoverable. The tax benefit recorded is due to Alternative Minimum Tax (“AMT”) credits that are expected to be recognized by the Company, which have been reduced for the anticipated sequestration. During the three months ended September 30, 2018, the Company estimated it would receive $0.2 million in AMT credits in 2018 and therefore setup an accounts receivable balance for that amount. The remaining $0.7 million of AMT credits, which is less anticipated sequestration, remain recorded as a deferred tax asset and are expected to be fully refundable in tax years 2019 - 2021 regardless of the Company's regular tax liability as a result of the repeal of the Corporate AMT under the Tax Cuts and Jobs Act. The Company no longer has a valuation allowance recorded against our estimate of refundable AMT credits. Considering the Company’s taxable income forecasts, our assessment of the realization of our deferred tax assets has not changed, and we continue to maintain a full valuation allowance for our net deferred tax assets as of September 30, 2018 aside from the deferred tax asset related to the AMT credits.

As of September 30, 2018, we have no unrecognized tax benefits. There were no significant changes to the calculation since December 31, 2017.

On December 22, 2017, the United States enacted tax reform legislation known as the H.R.1, commonly referred to

as the “Tax Cuts and Jobs Act”, resulting in significant modifications to existing law. Our financial statements for the year ended December 31, 2017 and now for the three and nine months ended September 30, 2018 reflect the effects of the Tax Cuts and Jobs Act which includes a reduction in the corporate tax rate from 35% to 21% effective January 1, 2018, as well as other changes. The Company follows the guidance in SEC Staff Accounting Bulletin 118 (“SAB 118”), which provides additional clarification regarding the application of ASC Topic 740 in situations where the Company does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act for the reporting period in which the Tax Cuts and Jobs Act was enacted. SAB 118 provides for a measurement period beginning in the reporting period that includes the Tax Cuts and Jobs Act’s enactment date and ending when the Company has obtained, prepared, and analyzed the information needed in order to complete the accounting requirements but in no circumstances should the measurement period extend beyond one year from the enactment date. We calculated the impact of the Tax Cuts and Jobs Act in our year ended December 31, 2017 income tax provision in accordance with our understanding of the Tax Cuts and Jobs Act and guidance available. We continue to gather and evaluate the income tax impact of the Tax Cuts and Jobs Act. The ultimate impact of the Tax Cuts and Jobs Act on our reported results in 2018 and beyond may differ, possibly materially, due to, among other things, changes in interpretations and assumptions we have made, guidance that may be issued, and other actions we may take as a result of the Tax Cuts and Jobs Act.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Commodity Derivative Activities

Commodity Derivative Activities

We use commodity and financial derivative contracts to manage fluctuations in commodity prices. We are currently not designating our derivative contracts for hedge accounting. All derivative gains and losses are from our oil and natural gas derivative contracts and have been recognized in “Other income (expense)” on our Consolidated Statements of Operations.

The following table summarizes gains and losses we recognized on our oil and natural gas derivatives for the three and nine months ended September 30, 2018 and 2017:

	Three Months Ended September 30,						Nine Months Ended September 30,
Oil and Natural Gas Derivatives (in thousands)	2018			2017			2018			2017

Total gain (loss) on commodity derivatives not designated as hedges	$	(237	)	$	(313	)	$	(3,392	)	$	193

Commodity Derivative Activity

We enter into swap contracts, costless collars or other derivative agreements from time to time to manage commodity price risk for a portion of our production. Our policy is that all derivatives are approved by the Hedging Committee of the Board, and reviewed periodically by the Board.

Despite the measures taken by us to attempt to control price risk, we remain subject to price fluctuations for natural gas and crude oil sold in the spot market. Prices received for natural gas sold on the spot market are volatile due primarily to seasonality of demand and other factors beyond our control. Decreases in domestic crude oil and natural gas spot prices will have a material adverse effect on our financial position, results of operations and quantities of reserves recoverable on an economic basis. We routinely exercise our contractual right to net realized gains against realized losses when settling with our financial counterparties. Neither our counterparties nor we require any collateral upon entering into derivative contracts. We were not at risk of losing any fair value amounts had our counterparties been unable to fulfill their obligations as of September 30, 2018.    

As of September 30, 2018, the open positions on our outstanding commodity derivative contracts, all of which were with JPMorgan Chase Bank, N.A. and BP Energy Company, were as follows:

Contract Type	Daily Volume	Total Volume	Fixed Price		Fair Value at September 30, 2018 (In thousands)
Oil swaps (Bbls)
2019	312	114,025	$	51.08	$	(2,075	)

Total Natural Gas					$	1,190
Total Oil and Natural Gas					$	(1,575	)

Subsequent to the third quarter of 2018 we entered into the following contracts with JPMorgan Chase Bank, N.A. and SunTrust Bank:

Contract Type	Daily Volume	Fixed Price		Contract Start Date	Contract Termination
JPMorgan Chase Bank natural gas swap (MMBtu)	10,000	$	2.867	January 1, 2019	December 31, 2019
SunTrust Bank natural gas swap (MMBtu)	20,000	$	2.866	January 1, 2019	December 31, 2019

The following table summarizes the fair values of our derivative financial instruments that are recorded at fair value classified in each Level as of September 30, 2018 (in thousands). We measure the fair value of our commodity derivative contracts by applying the income approach. See Note 1—“Description of Business and Significant Accounting Policies” for our discussion regarding fair value, including inputs used and valuation techniques for determining fair values.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The consolidated financial statements of the Company included in this Quarterly Report on Form 10-Q have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and accordingly, certain information normally included in financial statements prepared in accordance with United States Generally Accepted Accounting Principles (“US GAAP”) has been condensed or omitted. This information should be read in conjunction with our consolidated financial statements and notes contained in our annual report on Form 10-K for the year ended December 31, 2017. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the full year or for any interim period.

Principles of Consolidation

Principles of Consolidation—The consolidated financial statements include the financial statements of Goodrich and the Subsidiary. Intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements reflect all normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation. Certain data in prior periods’ financial statements have been adjusted to conform to the presentation of the current period. We have evaluated subsequent events through the date of this filing.

Use of Estimates

Use of Estimates— Our management has made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements in conformity with US GAAP.

Cash and Cash Equivalents

Cash and Cash Equivalents—Cash and cash equivalents includes cash on hand, demand deposit accounts and temporary cash investments with maturities of ninety days or less at the date of purchase.

Inventory

Inventory –Inventory consists of casing and tubulars that are expected to be used in our capital drilling program. Inventory is carried on the Consolidated Balance Sheets at the lower of cost or market.

Property and Equipment

Property and Equipment—Under US GAAP, two acceptable methods of accounting for oil and natural gas properties are allowed. These are the Successful Efforts Method and the Full Cost Method. Entities engaged in the production of oil and natural gas have the option of selecting either method for application in the accounting for their properties. The principal differences between the two methods are in the treatment of exploration costs, the computation of Depreciation, Depletion and Amortization (“DD&A”) expense and the assessment of impairment of oil and natural gas properties. We use the Full Cost Method to account for our investment in oil and gas properties.

Under the Full Cost Method, we capitalize all costs associated with acquisitions, exploration, development and estimated abandonment costs. We capitalize internal costs that can be directly identified with the acquisition of leasehold, as well as drilling and completion activities, but do not include any costs related to production, general corporate overhead or similar activities. Unevaluated property costs are excluded from the amortization base until we make a determination as to the existence of proved reserves on the respective property or impairment. We review our unevaluated properties at the end of each quarter to determine whether the costs should be reclassified to proved oil and natural gas properties and thereby subject to DD&A and the full cost ceiling test. For the three months ended September 30, 2018 and 2017, we transferred $5.7 million and $5.8 million, respectively, from unevaluated properties to proved oil and natural gas properties. For the nine months ended September 30, 2018 and 2017, we transferred $6.1 million and $18.6 million, respectively, from unevaluated properties to proved oil and natural gas properties. Our sales of oil and natural gas properties are accounted for as adjustments to net proved oil and natural gas properties with no gain or loss recognized, unless the adjustment would significantly alter the relationship between capitalized costs and proved reserves.

We amortize our investment in oil and natural gas properties through DD&A expense using the units of production (the “UOP”) method. An amortization rate is calculated based on total proved reserves converted to equivalent thousand cubic feet of natural gas (“Mcfe”) as the denominator and the net book value of evaluated oil and gas asset together with the estimated future development cost of the proved undeveloped reserves as the numerator. The rate calculated per Mcfe is applied against the periods' production also converted to Mcfe to arrive at the periods' DD&A expense.

Depreciation of furniture, fixtures and equipment, consisting of office furniture, computer hardware and software and leasehold improvements, is computed using the straight-line method over their estimated useful lives, which vary from three to five years.

Full Cost Ceiling Test—The Full Cost Method requires that at the conclusion of each financial reporting period, the present value of estimated future net cash flows from proved reserves (adjusted for hedges and excluding cash flows related to estimated abandonment costs), be compared to the net capitalized costs of proved oil and natural gas properties, net of related deferred taxes. This comparison is referred to as a "ceiling test". If the net capitalized costs of proved oil and natural gas properties exceed the estimated discounted future net cash flows from proved reserves, we are required to write-down the value of our oil and natural gas properties to the value of the discounted cash flows. Estimated future net cash flows from proved reserves are calculated based on a 12-month average pricing assumption.

Fair Value Measurement

Fair Value Measurement—Fair value is defined as the price 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. The fair value of an asset should reflect its highest and best use by market participants, whether in-use or an in-exchange valuation premise. The fair value of a liability should reflect the risk of non-performance, which includes, among other things, our credit risk.

We use various methods, including the income approach and market approach, to determine the fair values of our financial instruments that are measured at fair value on a recurring basis, which depend on a number of factors, including the availability of observable market data over the contractual term of the underlying instrument. For some of our instruments, the fair value is calculated based on directly observable market data or data available for similar instruments in similar markets. For other instruments, the fair value may be calculated based on these inputs as well as other assumptions related to estimates of future settlements of these instruments. We separate our financial instruments into three Levels (Levels 1, 2 and 3) based on our assessment of the availability of observable market data and the significance of non-observable data used to determine the fair value of our instruments. Our assessment of an instrument can change over time based on the maturity or liquidity of the instrument, which could result in a change in the classification of the instruments between Levels.

Each of these Levels and our corresponding instruments classified by Level are further described below:

• Level 1 Inputs— unadjusted quoted market prices in active markets for identical assets or liabilities. We have no Level 1 instruments;

• Level 2 Inputs— quotes that are derived principally from or corroborated by observable market data. Included in this Level are our 2017 Senior Credit Facility and commodity derivatives whose fair values are based on third-party quotes or available interest rate information and commodity pricing data obtained from third party pricing sources and our creditworthiness or that of our counterparties; and

• Level 3 Inputs— unobservable inputs for the asset or liability, such as discounted cash flow models or valuations, based on our various assumptions and future commodity prices. Included in this Level would be our initial measurement of asset retirement obligations.

As of September 30, 2018 and December 31, 2017, the carrying amounts of our cash and cash equivalents, trade receivables and payables represented fair value because of the short-term nature of these instruments.

Asset Retirement Obligations

Asset Retirement Obligations—Asset retirement obligations are related to the abandonment and site restoration requirements that result from the exploration and development of our oil and natural gas properties. We record the fair value of a liability for an asset retirement obligation in the period in which it is incurred and a corresponding increase in the carrying amount of the related long-lived asset. Accretion expense is included in “Depreciation, depletion and amortization” on our Consolidated Statements of Operations. See Note 3.

The estimated fair value of the Company’s asset retirement obligations at inception is determined by utilizing the income approach by applying a credit-adjusted risk-free rate, which takes into account the Company’s credit risk, the time value of money, and the current economic state, to the undiscounted expected abandonment cash flows. Given the unobservable nature of the inputs, the initial measurement of the asset retirement obligations was classified as Level 3 in the fair value hierarchy.

Revenue Recognition

Revenue Recognition—Oil and natural gas revenues are recognized upon delivery of our produced oil and natural gas volumes to our customers. Revenues from the production of crude oil and natural gas properties in which we have an interest with other producers are recognized in accordance with when the producing company records revenue on those volumes. We record a liability or an asset for natural gas balancing when we have sold more or less than our working interest share of natural gas production, respectively. AtSeptember 30, 2018and December 31, 2017, the net liability for natural gas balancing was immaterial. Differences between actual production and net working interest volumes are routinely adjusted.

Derivative Instruments

Derivative Instruments—We use derivative instruments such as futures, forwards, options, collars and swaps for purposes of hedging our exposure to fluctuations in the price of crude oil and natural gas and to hedge our exposure to changing interest rates. Accounting standards related to derivative instruments and hedging activities require that all derivative instruments subject to the requirements of those standards be measured at fair value and recognized as assets or liabilities in the balance sheet. We offset the fair value of our asset and liability positions with the same counterparty for each commodity type. Changes in fair value are required to be recognized in earnings unless specific hedge accounting criteria are met. All of our realized gain or losses on our derivative contracts are the result of cash settlements. We have not designated any of our derivative contracts as hedges; accordingly, changes in fair value are reflected in earnings.

Income Taxes

Income Taxes—We account for income taxes, as required, under the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

We recognize, as required, the financial statement benefit of an uncertain tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

Net Income or Net Loss Per Share

Net Income or Net Loss Per Share—Basic income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders for each reporting period by the weighted-average number of common shares outstanding during the period. Diluted income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders for each reporting period by the weighted-average number of common shares outstanding during the period, plus the effects of potentially dilutive restricted stock calculated using the treasury stock method and the potential dilutive effect of the conversion of convertible securities, such as warrants and convertible notes, into shares of our common stock.

Commitments and Contingencies

Commitments and Contingencies—Liabilities for loss contingencies, including environmental remediation costs, arising from claims, assessments, litigation, fines and penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Recoveries from third parties, when probable of realization, are separately recorded and are not offset against the related environmental liability.

Share-based Compensation

Share-Based Compensation—We account for our share-based transactions using the fair value as of the grant date and recognize compensation expense over the requisite service period.

Debt Issuance Cost

Debt Issuance Cost—The Company records debt issuance costs associated with its Convertible Second Lien Notes as a contra balance to long term debt, net in our Consolidated Balance Sheets, which is amortized straight-line over the life of the Convertible Second Lien Notes. Debt issuance costs associated with our revolving credit facility debt are recorded in other assets in our Consolidated Balance Sheets, which is amortized straight-line over the life of such debt.

New Accounting Pronouncements

New Accounting Pronouncements

On August 28, 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820 including the removal, modification and addition of certain disclosure requirements. For all entities, the amendments in this ASU are effective for fiscal periods beginning after December 15, 2019, including interim periods therein. We are evaluating the expected impact these amendments will have on our consolidated financial statements.

On June 20, 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. For public entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2018. We have not granted or issued share-based payments to nonemployees. We have evaluated the provisions of this ASU and do not expect it to have a material impact on our consolidated financial statements.

On March 13, 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740). The ASU adds seven paragraphs to the Accounting Standards Codification “ASC” 740, Income Taxes, that contain SEC guidance related to Staff Accounting Bulletin 118 (“Income Tax Accounting Implications of the Tax Cuts and Jobs Act”) as a result of the tax legislation passed in 2017 known as the “Tax Cuts and Jobs Act”. Specifically, the staff intended to address situations where the accounting under ASC Topic 740 is incomplete for certain income tax effects of the Tax Cuts and Jobs Act upon issuance of an entity’s financial statements for the reporting period in which the Tax Cuts and Jobs Act was enacted. The Company notes that it has considered the updates to ASC 740 as a result of the Tax Cuts and Jobs Act and has prepared its consolidated financial statements in accordance with the Tax Cuts and Jobs Act. See Note 7 for further discussion.

On August 28, 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU is intended to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this ASU make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP based on the feedback received from preparers, auditors, users, and other stakeholders. For public entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2018. We do not expect this ASU to have a material impact on our consolidated financial statements as we currently mark-to-market all of our derivative positions; however, we are evaluating the impact of this ASU should we choose to utilize hedge accounting in the future.

On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842) and subsequently issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements in July 2018. The key difference between the existing standards and ASU 2016-02 is the requirement for lessees to recognize on their balance sheet all lease contracts with lease terms greater than 12 months, including operating leases. Specifically, lessees are required to recognize on the balance sheet at lease commencement, both (i) a right-of-use asset, representing the lessee’s right to use the leased asset over the term of the lease, and (ii) a lease liability, representing the lessee’s contractual obligation to make lease payments over the term of the lease. For lessees, ASU 2016-02 requires classification of leases as either operating or finance leases, which are similar to the current operating and capital lease classifications. However, the distinction between these two classifications under the ASU does not relate to balance sheet treatment, but relate to treatment and recognition in the statements of income and cash flows. Lessor accounting is largely unchanged from current US GAAP. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, for public entities. Early application is permitted. The Company is carrying out its project plan to guide the implementation of ASU 2016-02, which includes assessing our portfolio of leases, determining a process for ensuring completeness of our repository of active leases, determining financial statement impacts and preparing for disclosure requirements under Topic 842. We have not yet completed our evaluation of the impact the new lease accounting guidance will have on our consolidated financial statements; however, we do expect to recognize right of use assets and lease liabilities for our operating leases with terms longer than 12 months in the Consolidated Balance Sheets upon adoption.
