In the opinion of management, these financial statements include all adjustments (consisting of normal recurring accruals and adjustments) necessary to present fairly, in all material respects, the Company’s interim financial position, results of operations and cash flows. However, the results of operations for the periods presented are not necessarily indicative of the results of operations that may be expected for the full year.

Recently Adopted Accounting Standards
Revenue From Contracts with CustomersLeases.. Effective January 1, 2018,2019, the Company adopted ASU No. 2014-09, Revenue From Contracts With Customers2016-02, Leases (Topic 606)842) (“ASC 606”842”), using the modified retrospective methodapproach and has applied the standard to all existing contracts. ASC 606 supersedes previous revenue recognition requirements in ASC 605 - Revenue Recognition (“ASC 605”) and includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration in exchange for those goods or services. As a result of adopting ASC 606, the Company did not have a cumulative-effect adjustment in retained earnings. The comparative information for the three and nine months ended September 30, 2017 has not been recast and continues to be reported under the accounting standards in effect for that period. Additionally, adoption of ASC 606 did not impact net income attributable to common shareholders and the Company does not expect that it will do so in future periods.

The tables below summarize the impact of adoption for the three and nine months ended September 30, 2018:

Changes to crude oil, NGL, and natural gas revenues and lease operating expense are due to the conclusion that the Company controls the product throughout processing before transferring to the customer for certain natural gas processing arrangements. Therefore, any transportation, gathering, and processing fees incurred prior to transfer of control are included in lease operating expense.
Business Combinations. In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or divestitures) of assets or businesses. Effective January 1, 2018, the Company adopted ASU 2017-01 using the prospective method and will apply the clarified definition of a business to future acquisitions and divestitures.
Statement of Cash Flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The guidance addresses eight specific cash flow issues for which current GAAP is either unclear or does not include specific guidance. Effective January 1, 2018, the Company adopted ASU 2016-15 using the retrospective approach as prescribed by ASU 2016-15. There were no changes to the statement of cash flowsearnings as a result of adoption.
Recently Issued Accounting Pronouncements
Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), whichadoption. ASC 842 significantly changes accounting for leases by requiring that lessees recognize a right-of-use (“ROU”) asset and a related lease liability representing the obligation to make lease payments and a related right-of-use (“ROU”) asset for virtually all lease transactions. ASU 2016-02However, ASC 842 does not apply to leases of mineral rights to explore for or use crude oil and natural gas. Additional disclosures about an entity’s lease transactions will also be required. ASU 2016-02 defines a lease as “a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (an identified asset) for a period of time in exchange for consideration.” ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018 with earlyUpon adoption, permitted. ASU 2016-02 requires companies to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach.

The Company is in the process of reviewing and determining the contracts to which ASU 2016-02 applies with the assistance of a third party consultant. These include contracts such as non-cancelable leases, drilling rig contracts, pipeline gathering, transportation and gas processing agreements, and contracts for the use of vehicles and well equipment. The Company continues to review current accounting policies, controls, processes, and disclosures that will change as a result of adopting the new standard. Based upon its initial assessment, the Company expectsimplemented policy elections and practical expedients which include the adoptionfollowing:
package of ASU 2016-02 will result in: (i) an increase in assets and liabilities due to the required recognition of ROU assets and corresponding lease liabilities, (ii) increases in depreciation, depletion and amortization and interest expense, (iii) decreases in lease operating and general and administrative expense and (iv) additional disclosures, however, the full impact to the Company’s consolidated financial statements and related disclosures is still being evaluated. Currently,practical expedients which allows the Company plans to make certain elections allowing the Company not to reassessavoid reassessing contracts that commenced prior to adoption to continue applying its currentthat were properly evaluated under legacy lease accounting policy for land easements, and not to recognizeguidance;
excluding ROU assets orand lease liabilities for short-term leases. The Company plansleases with terms that are less than one year;
combining lease and non-lease components and accounting for them as a single lease (elected by asset class);
excluding land easements that existed or expired prior to adoptadoption; and
policy election that eliminates the guidance on the effective dateneed for adjusting prior period comparable financial statements prepared under legacy lease accounting guidance.
As a result of January 1, 2019. As permitted by ASU No. 2018-11, Leases (Topic 842): Targeted Improvements,adopting ASC 842, the Company does not expect to adjust comparative-period financial statements.
Revenue Recognition
The Company’s revenues are comprised solelyrecorded lease liabilities of revenues from customersapproximately $75.2 million and include the saleassociated ROU assets of crude oil, NGLs, and natural gas. The Company believes that the disaggregation of revenue into these three major product types appropriately depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors basedapproximately $69.1 million on its single geographic location. Crude oil, NGL, and natural gas revenues are recognized at a point in time when production is sold to a purchaser at a fixed or determinable price, delivery has occurred, control has transferred and collectability of the revenue is probable. The transaction price used to recognize revenue is a function of the contract billing terms. Revenue is invoiced by calendar month based on volumes at contractually based rates with payment typically required within 30 days of the end of the production month. At the end of each month when the performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from customers are accrued in “Accounts receivable, net” in the consolidated balance sheets. As of September 30, 2018The difference between the lease liabilities and December 31, 2017, receivables from contracts with customers were $100.2 million and $85.6 million, respectively. Taxes assessed by governmental authorities on crude oil, NGL, and natural gas sales are presented separately from such revenues in the consolidated statements of income.
Crude oil sales. Crude oil productionROU assets is primarily sold at the wellhead at an agreed upon index price, net of pricing differentials. Revenue is recognized when control transfers to the purchaser at the wellhead, net of transportation costs incurred by the purchaser.
Natural gas and NGL sales. Natural gas is delivereddue to a midstream processing entity atrent holiday and lease build-out incentives that were recorded as deferred lease liabilities under legacy lease accounting guidance. The adoption of ASC 842 did not materially change the wellhead or the inlet of the midstream processing entity’s system. The midstream processing entity gathers and processes the natural gas and remits proceeds for the resulting sales of NGLs and residue gas. The Company evaluates whether it is the principal or agent in the transaction and has concluded it is the principal and the purchasers of the NGLs and residue gas are the customers. Revenue is recognized on a gross basis, with gathering, processing and transportation fees recognized as lease operating expense in theCompany’s consolidated statements of income as the Company maintains control throughout processing.or consolidated statements of cash flows. See “Note 5. Leases” for further discussion.
Transaction Price Allocated to Remaining Performance Obligations. Subsequent Events
The Company appliedevaluates subsequent events through the practical expedient in ASC 606 exemptingdate the disclosure of the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Each unit of product typically represents a separate performance obligation, therefore, future volumesfinancial statements are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.issued. See “Note 15. Subsequent Events” for further discussion.

3. Acquisitions and Divestitures of Oil and Gas Properties
2019 Acquisitions and Divestitures
The Company did not have any material acquisitions or divestitures for the three months ended March 31, 2019.
2018 Acquisitions and Divestitures
Devon Acquisition. On August 13, 2018, the Company entered into a purchase and sale agreement with Devon Energy Production Company, L.P. (“Devon”), a subsidiary of Devon Energy Corporation, to acquire oil and gas properties in the Delaware Basin in Reeves and Ward counties, Texas (the “Devon��Devon Properties”) for an agreed upon price of $215.0 million, with an effective date of April 1, 2018, subject to customary purchase price adjustments (the “Devon Acquisition”). The Company paid $21.5 million as a deposit on August 13, 2018, and $183.4 million upon initial closing on October 17, 2018, which included purchase price adjustments primarily related to the net cash flows from the effective date to the closing date,and received $8.3 million as a post-closing adjustment on March 28, 2019, for an estimated aggregate purchase price of $204.9$196.6 million. The final purchase price remains subject to post-closing adjustments.
Under one of the Company’s existing joint operating agreements covering acreage in the vicinity of the Devon Properties, the other party to the joint operating agreement has a right to purchase a 20% interest in certain of the acres within the Devon Properties acquired by the Company at a price based on the Company’s cost to acquire the Devon Properties. This right is exercisable for a 30-day period after the Company delivers a specified notice following the closing of the Devon Acquisition and, if not exercised, will expire in the fourth quarter of 2018. To the extent that the other party exercises its right to make such purchase, the Company’s interests in the Devon Properties will be reduced and the proceeds received will be recognized as a reduction of proved oil and gas properties.
The Company funded the Devon Acquisition with net proceeds from the common stock offering completed on August 17, 2018, which, pending the closing of the Devon Acquisition, were used to temporarily repay a portion of the borrowings outstanding under the revolving credit facility. See “Note 9. Shareholders’ Equity and Stock-Based Compensation” for details regarding the common stock offering.

The Devon Acquisition will bewas accounted for as a business combination.combination, therefore, the purchase price was allocated to the assets acquired and the liabilities assumed based on their estimated acquisition date fair values based on then currently available information. A combination of a discounted cash flow model and market data was used by a third-party valuation specialist in determining the fair value of the oil and gas properties. Significant inputs into the calculation included future commodity prices, estimated volumes of oil and gas reserves, expectations for timing and amount of future development and operating costs, future plugging and abandonment costs and a risk adjusted discount rate. The Company has not completed its initialfollowing table presents the preliminary allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated acquisition date fair values.

As part of the ExL Acquisition, the Company agreed to a contingent consideration arrangement (the “Contingent ExL Consideration”), which was determined to be an embedded derivative. As a result, the liability is recorded at fair value in the consolidated balance sheets with all gains and losses as a result of changes in the fair value between periods recognized in the consolidated statements of income in the period in which the changes occur. See “Note 10. Derivative Instruments” and “Note 11. Fair Value Measurements” for further details.
The ExL Acquisition was accounted for as a business combination, therefore, the purchase price was allocated to the assets acquired and the liabilities assumed based on their estimated acquisition date fair values based on then currently available information. A combination of a discounted cash flow model and market data was used by a third-party valuation specialist in determining the fair value of the oil and gas properties. Significant inputs into the calculation included forward oil and gas price curves, estimated volumes of oil and gas reserves, expectations for timing and amount of future development and operating costs, future plugging and abandonment costs and a risk adjusted discount rate. The fair value of the Contingent ExL Consideration was determined by a third-party valuation specialist using a Monte Carlo simulation. Significant inputs into the calculation included forward oil and gas price curves, volatility factors, and a risk adjusted discount rate. See “Note 11. Fair Value Measurements” for further details.

5. Leases
The Company determines if an arrangement is a lease at inception of the contract and, $27.6 million and $16.2 millionif the contract is determined to be a lease, classifies the lease as an operating or financing lease. The Company recognizes an operating or financing lease on its consolidated balance sheets as a lease liability, which represents the present value of the Company’s obligation to make lease payments arising from the lease, with a related ROU asset, which represents the Company’s right to use the underlying asset for the ninelease term. The Company’s operating leases typically do not provide an implicit interest rate, therefore, the Company utilizes its incremental borrowing rate to calculate the present value of the lease payments based on information available at inception of the contract.
Lease expense for operating leases is recognized on a straight-line basis over the lease term. Lease expense for financing leases is comprised of interest expense on the financing lease liability and the amortization of the associated ROU asset, which is recognized on a straight-line basis over the lease term. Variable lease expense that is not dependent on an index or rate is not included in the operating or financing lease liability or ROU asset and is recognized in the period in which the obligation for those payments is incurred.
Types of Leases
The Company currently has leases associated with contracts for drilling rigs, office space, and the use of well equipment, vehicles, information technology infrastructure, and other office equipment, with the significant lease types described in more detail below.
Drilling Rigs. The Company enters into contracts for drilling rigs with third parties to support its development plan. These contracts are typically for one to three years and can be extended upon mutual agreement with the third party by providing written notice at least thirty days prior to the end of the primary contractual term. The Company exercises its discretion in choosing whether or not to extend these contracts on a drilling rig by drilling rig basis as a result of evaluating the conditions that exist at the time the contract expires, such as availability of drilling rigs and the Company’s development plan. The Company has determined that it cannot conclude with reasonable certainty that it will choose to extend the contract past its primary term. As such, the Company uses the primary term in its calculation of the lease liability and ROU asset. The Company classifies its drilling rigs as operating leases and capitalizes the costs of the drilling rigs to oil and gas properties.
Office Space. The Company leases office space from third parties for its corporate office and certain field locations. These leases have non-cancelable terms between one to fifteen years. The Company has determined that it cannot conclude with reasonable

certainty that it will exercise any option to extend the contract past the non-cancelable term. As such, the Company uses the non-cancelable term in its calculation of the lease liability and ROU asset. The Company classifies its leases for office space as operating leases with the costs recognized as “General and administrative, net” in its consolidated statements of income.
Well Equipment. The Company rents compressors from third parties to facilitate the flow of production from its drilling operations to market. These contracts range from less than one year to three years for the primary term and continue thereafter on a month to month basis subject to cancellation by either party with thirty days notice. The Company classifies the compressors as operating leases with a lease term equal to the primary term for those contracts that have a primary term greater than one year. After the primary term, each party has a substantive right to terminate the lease, therefore, enforceable rights and obligations do not exist subsequent to the primary term. For those contracts that are less than one year, the Company has concluded that they represent short-term operating leases and therefore, an operating lease liability and ROU asset is not recorded in the consolidated balance sheets. These lease payments are recognized as “Lease operating expense” in the Company’s statements of income.
The tables below, which present the components of lease costs, supplemental balance sheet information, and supplemental cash flow information, are presented on a gross basis. Other joint owners in the properties operated by the Company generally pay for their working interest share of costs associated with drilling rigs and well equipment.

5.6. Income Taxes
The Company’s estimated annual effective income tax rates are used to allocate expected annual income tax expense or benefit to interim periods. The rates are the ratio of estimated annual income tax expense or benefit to estimated annual income or loss before income taxes by taxing jurisdiction, excluding significant unusual or infrequent items, the tax effects of statutory rate changes, certain changes in the assessment of the realizability of deferred tax assets, and excess tax benefits or deficiencies related to the vesting of stock-based compensation awards, which are recognized as discrete items in the interim period in which they occur.
The Company’s income tax expense differs(expense) benefit differed from the income tax expense(expense) benefit computed by applying the U.S. federal statutory corporate income tax rate of 21% for the three and nine months ended September 30,March 31, 2019 and 2018, and 35% for the three and nine months ended September 30, 2017, to income (loss) before income taxes as follows:

Tax Cuts and Jobs Act
On December 22, 2017, the U.S. Congress enacted the Tax Cuts and Jobs Act (the “Act”) which made significant changes to U.S. federal income tax law, including lowering the U.S. federal statutory corporate income tax rate to 21% from 35% beginning January 1, 2018. Due to the uncertainty regarding the application of ASC 740 in the period of enactment of the Act, the SEC issued Staff Accounting Bulletin 118 which allowed the Company to provide a provisional estimate of the impacts of the Act in earnings for the year ended December 31, 2017 and also provided a one-year measurement period in which the Company would record additional impacts from the enactment of the Act as they are identified. In August 2018, the Internal Revenue Service issued Notice 2018-68, Guidance on the Application of Section 162(m) (“Notice 2018-68”), which provides initial guidance on the application of Section 162(m), as amended. Notice 2018-68 provided guidance regarding the group of covered employees subject to Section 162(m)’s deduction limit under the Act and the scope of transition relief available under the Act. The Company is currently evaluating the impact of Notice 2018-68, but as of September 30, 2018, has not made any changes to the provisional estimate recorded in earnings for the year ended December 31, 2017. While the Company has made a reasonable estimate of the effects on its existing deferred tax balances, it has not completed its accounting for the tax effects of the enactment of the Act and will continue to monitor provisions with discrete rate impacts and additional guidance provided within the one year measurement period.

Deferred Tax Asset Valuation Allowance
The deferred tax asset valuation allowance was $299.1$67.7 million and $333.0$242.9 million as of September 30, 2018March 31, 2019 and December 31, 2017,2018, respectively. Decreases in the valuation allowance for the three months and nine months ended September 30, 2018 and 2017 were based primarily on the pre-tax income recorded during those periods.
Throughout 2017 and the first nine months of 2018, the Company maintained a full valuation allowance against its deferred tax assets based on its conclusion, considering all available evidence (both positive and negative), that it was more likely than not that

the deferred tax assets would not be realized. TheA significant item of objective negative evidence considered was the cumulative pre-tax loss incurred over the three-year period ended December 31, 2018, primarily due to impairments of proved oil and gas properties recognized in the first three quarters of 2016. As of March 31, 2019, the Company intends to maintainis in a full valuation allowance against itscumulative pre-tax income position. Based on this factor, as well as other positive evidence including projected future taxable income for the current and future years, the Company concluded that it is more likely than not that the deferred tax assets until therewould be realized and released $179.1 million of the valuation allowance, which is sufficient evidence to supportrecognized as an increase in deferred tax assets and an income tax benefit for the reversal of such valuation allowance.three months ended March 31, 2019.

See “Note 14. Subsequent Events” for details regarding the maturity date of the credit agreement upon redemption of the remaining $130.0 million outstanding aggregate principal amount of its 7.50% Senior Notes. The borrowing base under the credit agreement is subject to regular redeterminations in the spring and fall of each year, as well as special redeterminations described in the credit agreement, which in each case may reduce the amount of the borrowing base.

On October 29, 2018, the Company entered into the thirteenth amendment to its credit agreement governing the revolving credit facility. See “Note 14. Subsequent Events” for further details of the thirteenth amendment.definitions and provisions.
The obligations of the Company under the credit agreement are guaranteed by the Company’s material subsidiaries and are secured by liens on substantially all of the Company’s assets, including a mortgage lien on oil and gas properties having at least 90% of the total value of the oil and gas properties included in the Company’s reserve report used in its most recent redetermination.

Borrowings outstanding under the credit agreement bear interest at the Company’s option at either (i) a base rate for a base rate loan plus the margin set forth in the table below, where the base rate is defined as the greatest of the prime rate, the federal funds rate plus 0.50% and the adjusted LIBO rate plus 1.00%, or (ii) an adjusted LIBO rate for a Eurodollar loan plus the margin set forth in the table below. The Company also incurs commitment fees at rates as set forth in the table below on the unused portion of lender commitments, which are included in “Interest expense, net” in the consolidated statements of income.

The Company is subject to certain covenants under the terms of the credit agreement, which include the maintenance of the following financial covenants determined as of the last day of each quarter: (1) a ratio of Total Debt to EBITDA of not more than 4.00 to 1.00 and (2) a Current Ratio of not less than 1.00 to 1.00. As defined in the credit agreement, Total Debt excludes debt premiums and debt issuance costs and is net of cash and cash equivalents, EBITDA will beis calculated based on the last four fiscal quarters after giving pro forma effect to EBITDA for material acquisitions and divestitures of oil and gas properties, and the Current Ratio includes an add back of the unused portion of lender commitments.commitments and excludes the Contingent ExL Consideration, which is described in “Note 12. Derivative Instruments.” As of September 30, 2018,March 31, 2019, the ratio of Total Debt to EBITDA was 1.952.40 to 1.00 and the Current Ratio was 1.841.58 to 1.00. Because the financial covenants are determined as of the last day of each quarter, the ratios can fluctuate significantly period to period as the level of borrowings outstanding under the credit agreement are impacted by the timing of cash flows from operations, capital expenditures, acquisitions and divestitures of oil and gas properties and securities offerings.
The credit agreement also places restrictions on the Company and certain of its subsidiaries with respect to additional indebtedness, liens, dividends and other payments to shareholders, repurchases or redemptions of the Company’s common stock, redemptions

of senior notes, investments, acquisitions and divestitures of oil and gas properties, mergers, transactions with affiliates, hedging transactions and other matters.
The credit agreement is subject to customary events of default, including in connection with a change in control. If an event of default occurs and is continuing, the lenders may elect to accelerate amounts due under the credit agreement (except in the case of a bankruptcy event of default, in which case such amounts will automatically become due and payable).
Redemptions of 7.50% Senior Notes

7.8. Commitments and Contingencies
From time to time, the Company is party to certain legal actions and claims arising in the ordinary course of business. While the outcome of these events cannot be predicted with certainty, management does not currently expect these matters to have a materially adverse effect on the financial position or results of operations of the Company.
The results of operations and financial position of the Company continue to be affected from time to time in varying degrees by domestic and foreign political developments as well as legislation and regulations pertaining to restrictions on oil and gas production, imports and exports, tax changes, environmental regulations and cancellation of contract rights.

Each restricted stock award and unit and performance share granted under the 2017 Incentive Plan counts as 1.35 shares against the Maximum Share Limit. Each stock option and stock appreciation right to be settled in shares of common stock granted under the 2017 Incentive Plan counts as 1.00 share against the Maximum Share Limit. Stock appreciation rights to be settled in cash granted under the 2017 Incentive Plan and stock appreciation rights granted under the Cash SAR Plan (collectively, “Cash SARs”) do not count against the Maximum Share Limit. Restricted stock awards and units, performance shares, and Cash SARs activity during the nine months ended September 30, 2018 is presented below. The Company has not granted stock appreciation rights to be settled in shares of common stock and has no outstanding stock options. AsSee “Note 11.

12. Derivative Instruments
Commodity Derivative Instruments
The Company uses commodity derivative instruments to mitigate the effects of commodity price volatility for a portion of its forecasted sales of production and achieve a more predictable level of cash flow. Since the Company derives a significant portion of its revenues from sales of crude oil, crude oil price volatility represents the Company’s most significant commodity price risk.

While the use of commodity derivative instruments limits or partially reduces the downside risk of adverse commodity price movements, such use also limits the upside from favorable commodity price movements. The Company does not enter into commodity derivative instruments for speculative purposes.
The Company’s commodity derivative instruments, which settle on a monthly basis over the term of the contract for contracted volumes, consist of over-the-counter price swaps, three-way collars, sold call options, and basis swaps, each of which is described below.
Price swaps are settled based on differences between a fixed price and the settlement price of a referenced index. If the settlement price of the referenced index is below the fixed price, the Company receives the difference from the counterparty. If the referenced settlement price is above the fixed price, the Company pays the difference to the counterparty.
Three-way collars consist of a purchased put option (floor price), a sold call option (ceiling price) and a sold put option (sub-floor price) and are settled based on differences between the floor or ceiling prices and the settlement price of a referenced index or the difference between the floor price and sub-floor price. If the settlement price of the referenced index is below the sub-floor price, the Company receives the difference between the floor price and sub-floor price from the counterparty. If the settlement price of the referenced index is between the floor price and sub-floor price, the Company receives the difference between the floor price and the settlement price of the referenced index from the counterparty. If the settlement price of the referenced index is between the floor price and ceiling price, no payments are due to or from either party. If the settlement price of the referenced index is above the ceiling price, the Company pays the difference to the counterparty.
Sold call options are settled based on differences between the ceiling price and the settlement price of a referenced index. If the settlement price of the referenced index is above the ceiling price, the Company pays the difference to the counterparty. If the settlement price of the referenced index is below the ceiling price, no payments are due to or from either party. Premiums from the sale of call options have been used to enhance the fixed price of certain contemporaneously executed price swaps. Purchased call options executed contemporaneously with sold call options in order to increase the ceiling price of existing sold call options have been presented on a net basis in the table below.
Basis swaps are settled based on differences between a fixed price differential and the differential between the settlement prices of two referenced indexes. If the differential between the settlement prices of the two referenced indexes is greater than the fixed price differential, the Company receives the difference from the counterparty. If the differential between the settlement prices of the two referenced indexes is less than the fixed price differential, the Company pays the difference to the counterparty.
The referenced index of the Company’s price swaps, three-way collars, and sold call options is U.S. New York Mercantile Exchange (“NYMEX”) West Texas Intermediate (“WTI”) for crude oil and NYMEX Henry Hub for natural gas, and OPIS Mont Belvieu Non-TET (“OPIS”) for NGL products, as applicable. The prices received byindex price the Company for the sale ofreceives on its production generally vary from these referenced index prices due to adjustments for delivery location (basis) and other factors. The referenced indexes of the Company’scrude oil basis swaps which are used to mitigate location price risk for a portion of its production, areis Argus WTI Cushing (“WTI Cushing”) plus or minus a fixed price differential and the applicable index price of the Company’s crude oil sales contractsit pays is Argus WTI Midland (“WTI Midland”) for its Delaware Basin crude oil production andor Argus Light Louisiana Sweet (“LLS”) for. The index price the Company receives on its Eagle Ford crude oil production.

natural gas basis swaps is NYMEX Henry Hub minus a fixed price differential and the index price it pays is Platt’s Inside FERC West Texas Waha (“Waha”).
The Company has incurred premiums on certain of its commodity derivative instruments in order to obtain a higher fixed price, higher floor price and/or higher ceiling price. Payment of these premiums are deferred until the applicable contracts settle on a monthly basis over the term of the contract or, in some cases, during the final 12 months of the contract and are referred to as deferred premium obligations.

As of September 30, 2018,March 31, 2019, the Company had the following outstanding commodity derivative instruments at weighted average contract volumes and prices:

The Company typically has numerous commodity derivative instruments outstanding with a counterparty that were executed at various dates, for various contract types, commodities and time periods often resulting in both commodity derivative asset and liability positions with that counterparty. The Company nets its commodity derivative instrument fair values executed with the same counterparty, along with any deferred premium obligations, to a single asset or liability pursuant to International Swap Dealers Association Master Agreements (“ISDAs”), which provide for net settlement over the term of the contract and in the event of default or termination of the contract.
Counterparties to the Company’s commodity derivative instruments who are also lenders under the Company’s credit agreement (“Lender Counterparty”) allow the Company to satisfy any need for margin obligations associated with commodity derivative instruments where the Company is in a net liability position with the Lender Counterparty with the collateral securing the credit

agreement, thus eliminating the need for independent collateral posting. Counterparties to the Company’s commodity derivative instruments who are not lenders under the Company’s credit agreement (“Non-Lender Counterparty”) can require commodity derivative instruments to be novated to a Lender Counterparty if the Company’s net liability position exceeds the Company’s unsecured credit limit with the Non-Lender Counterparty and therefore do not require the posting of cash collateral.

Because each Lender Counterparty has an investment grade credit rating and the Company has obtained a guaranty from each Non-Lender Counterparty’s parent company which has an investment grade credit rating, the Company believes it does not have significant credit risk and accordingly does not currently require its counterparties to post collateral to support the net asset positions of its commodity derivative instruments. Although the Company does not currently anticipate nonperformance from its counterparties, it continually monitors the credit ratings of each Lender Counterparty and each Non-Lender Counterparty’s parent company. TheAs of March 31, 2019, the Company executes itshas outstanding commodity derivative instruments with seventeenfifteen counterparties to minimize its credit exposure to any individual counterparty.
Contingent Consideration Arrangements
The purchase and sale agreements for the acquisition of properties in the Delaware Basin from ExL AcquisitionPetroleum Management, LLC and ExL Petroleum Operating Inc. (the “ExL Acquisition”) in 2017 and divestitures of the Company’s assets in the Niobrara in 2018, and Marcellus and Utica in 2017, included contingent consideration arrangements that require the Company to pay or entitle the Company to receive or require the Company to pay specified amounts if commodity prices exceed specified thresholds, which are summarized in the tabletables below. See “Note 3. Acquisitions and Divestitures of Oil and Gas Properties” of the Notes to Consolidated Financial Statements in the 2018 Annual Report for detailsfurther discussion of these acquisitions and divestitures.transactions.

Administration (“U.S. EIA”).
(2)Cash paid for settlements of contingent consideration arrangements are classified as cash flows from financing activities up to the acquisition date fair value with any excess classified as cash flows from operating activities. Therefore, if the commodity price threshold is reached, $2.3 million of the next contingent payment will be presented in cash flows from financing activities with the remainder, as well as all subsequent contingent payments, presented in cash flows from operating activities. If the pricing threshold is met, the payment is made and the cash flow occurs, in the first quarter of the following year.

11.13. Fair Value Measurements
Accounting guidelines for measuring fair value establish a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:
Level 1 – Observable inputs such as quoted prices in active markets at the measurement date for identical, unrestricted assets or liabilities.
Level 2 – Other inputs that are observable directly or indirectly such as quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3 – Unobservable inputs for which there is little or no market data and which the Company makes its own assumptions about how market participants would price the assets and liabilities.

Assets and Liabilities Measured at Fair Value on a Recurring Basis
The following tables summarize the Company’s derivative instrument assets and liabilities measured at fair value on a recurring basis as of September 30, 2018March 31, 2019 and December 31, 2017:2018:

The asset and liability fair values reported in the consolidated balance sheets are as of the balance sheet date and subsequently change as a result of changes in commodity prices, market conditions and other factors.
Commodity derivative instruments. The fair value of the Company’s commodity derivative instruments is based on a third-party industry-standard pricing model which uses contract terms and prices and assumptions and inputs that are substantially observable in active markets throughout the full term of the instruments including forward oil and gas price curves, discount rates and volatility factors, and are therefore designated as Level 2 within the valuation hierarchy. The fair values are also compared to the values provided by the counterparties for reasonableness and are adjusted for the counterparties’ credit quality for commodity derivative assets and the Company’s credit quality for commodity derivative liabilities.
The Company had no transfers into Level 1 and no transfers into or out of Level 2 for the nine months ended September 30, 2018 and 2017.
Contingent consideration arrangements. The fair values of the contingent consideration arrangements were determined by a third-party valuation specialist using Monte Carlo simulations including significant inputs such as forward oil and gas price curves, volatility factors, and risk adjusted discount rates, which include adjustments for the counterparties’ credit quality for contingent consideration assets and the Company’s credit quality for the contingent consideration liabilities. As some of these assumptionsliability. These inputs are not substantially

observable in active markets throughout the full term of the contingent consideration arrangements the contingent consideration arrangements wereor can be derived from observable data and are therefore designated as Level 32 within the valuation hierarchy. The Company reviewed the valuations, including the related inputs, and analyzed changes in fair value measurements between periods.

The following table presents the reconciliation of changes in the fair values of the contingent consideration arrangements, which were designated as Level 3 within the valuation hierarchy, for the nine months ended September 30, 2018 and 2017:

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis
The fair value measurements of asset retirement obligations are measured as of the date a well is drilled or when production equipment and facilities are installed using a discounted cash flow model based on inputs that are not observable in the market and therefore are designated as Level 3 within the valuation hierarchy. Significant inputs to the fair value measurement of asset retirement obligations include estimates of the costs of plugging and abandoning oil and gas wells, removing production equipment and facilities and restoring the surface of the land as well as estimates of the economic lives of the oil and gas wells and future inflation rates.
The fair value measurements of assets acquired and liabilities assumed, other than contingent consideration which is discussed above, are measured as of the acquisition date by a third-party valuation specialist using a discounted cash flow model based on inputs that are not observable in the market and are therefore designated as Level 3 inputs. Significant inputs to the valuation of acquired oil and gas properties include forward oil and gas price curves, estimated volumes of oil and gas reserves, expectations for timing and amount of future development and operating costs, future plugging and abandonment costs, and a risk adjusted discount rate. See “Note 3. Acquisitions and Divestitures of Oil and Gas Properties” for detailsadditional discussion.

Significant inputs to the fair value measurement of asset retirement obligations include estimates of the costs of plugging and abandoning oil and gas wells, removing production equipment and facilities and restoring the surface of the land as well as estimates of the economic lives of the oil and gas wells and future inflation rates.

The fair value measurements of the Preferred Stock are measured as of the issuance date by a third-party valuation specialist using a discounted cash flow model based on inputs that are not observable in the market and therefore are designated as Level 3 inputs. Significant inputs to the valuation of the Preferred Stock include the per share cash purchase price, redemption premiums, liquidation preference, and redemption assumptions provided by the Company.
Fair Value of Other Financial Instruments
The Company’s other financial instruments consist of cash and cash equivalents, receivables, payables, and long-term debt. The carrying amounts of cash and cash equivalents, receivables, and payables approximate fair value due to the highly liquid or short-term nature of these instruments. The carrying amount of long-term debt associated with borrowings outstanding under the Company’s revolving credit facility approximates fair value as borrowings bear interest at variable rates. The following table presents the carryingprincipal amounts of the Company’s senior notes and other long-term debt net of unamortized premiums and debt issuance costs with the fair values measured using quoted secondary market trading prices which are designated as Level 1 within the valuation hierarchy.

Redemption of 7.50% Senior Notes Due 2020
On October 18, 2018, the Company delivered a notice of conditional redemption to the trustee for its 7.50% Senior Notes to call for redemption on November 19, 2018, the remaining $130.0 million outstanding aggregate principal amount of 7.50% Senior Notes at a redemption price of 100% of par, plus accrued and unpaid interest. The Company’s redemption obligation was conditioned on and subject to there being made available to the Company under its revolving credit facility a commitment amount of at least $1.1 billion as of November 19, 2018, which was satisfied on October 29, 2018 in connection with the amendment to the credit agreement discussed below, therefore, the Company’s redemption obligation is no longer conditional. As a result of the redemption, the Company expects to record a loss on extinguishment of debt of approximately $0.8 million, which is solely attributable to the write-off of unamortized premium and debt issuance costs.
Upon redemption of the 7.50% Senior Notes, the May 4, 2022 maturity date of the credit agreement will no longer be subject to a springing maturity date of June 15, 2020.
Thirteenth Amendment to the Credit Agreement
On October 29, 2018, the Company entered into the thirteenth amendment to its credit agreement governing its revolving credit facility to, among other things, (i) establish the borrowing base at $1.3 billion, with an elected commitment amount of $1.1 billion, until the next redetermination thereof, (ii) reduce the applicable margins for Eurodollar loans from 1.50%-2.50% to 1.25%-2.25% and base rate loans from 0.50%-1.50% to 0.25%-1.25%, each depending on the level of facility usage and each subject to an increase of 0.25% for any period during which the ratio of Total Debt to EBITDA exceeds 3.00 to 1.00, (iii) amend the definition of Capital Leases, and (iv) amend certain other definitions and provisions.

Drilling and completion expenditures for the thirdfirst quarter of 20182019 were $241.1$214.7 million, of which approximately 62%63% were in the Eagle Ford with the balance in the Delaware Basin. As a result of the relative outlook for crude oil prices in the Eagle Ford and Delaware Basin, we elected to shift capital expenditures to the Eagle Ford in order to take advantage of the superior returns in the current environment. As of September 30, 2018,March 31, 2019, we were operating sixthree rigs, with fourone located in the Eagle Ford and two located in the Delaware Basin, and two completion crews, both of which were in the Eagle Ford.Basin. For the remainder of 2018,2019, we currently expect to continue operatingoperate an average of sixthree to four rigs between the Eagle Ford and Delaware Basin, however, completion activity is expected to decline in the fourth quarter of 2018 as we have planned for a frac holiday.Basin. Our current 20182019 drilling, completion, and infrastructure (“DC&I”) capital expenditure plan remains unchanged at $800.0$525.0 million to $825.0$575.0 million. See “—Liquidity and Capital Resources—2018 Drilling, Completion, and Infrastructure2019 DC&I Capital Expenditure Plan and Funding Strategy” for additional details.
In July 2018,January 2019, we closed on the divestiture of certain non-operated assets in the Delaware Basin for aggregate net proceeds of $30.9 million.
In August 2018, we entered into a purchase and sale agreement with Devon to acquire oil and gas properties in the Delaware Basin in Reeves and Ward counties, Texas for an agreed upon price of $215.0paid $50.0 million subject to customary purchase price adjustments. We paid $21.5 million as a deposit upon signing the purchase and sale agreement and $183.4 million upon closing in October for an aggregate purchase price of $204.9 million. The final purchase price remains subject to post-closing adjustments. Certain of the acreage included in the acquisition is subject to a third party’s right to purchase a 20% interest in such acreage.
In August 2018, we completed a public offering of 9.5 million shares of our common stock at a price per share of $22.55. We used the net proceeds of $213.9 million, net of offering costs, to fund the purchase price of the Devon Acquisition and for general corporate purposes. Pending the closing of the Devon Acquisition, we used the net proceeds to temporarily repay a portion of the borrowings outstanding under the revolving credit facility.
We recorded net income attributable to common shareholders for the three months ended September 30, 2018 of $76.1 million, or $0.85 per diluted share, as compared to net income attributable to common shareholders for the three months ended September 30, 2017 of $5.6 million, or $0.07 per diluted share. The increase in net income attributable to common shareholders for the third quarter of 2018 as compared to the net income attributable to common shareholders for the third quarter of 2017 was driven primarily by higher production volumes and commodity prices in the third quarter of 2018 compared to the third quarter of 2017, partially offset by a loss on derivatives, net of $55.4 million in the third quarter of 2018 as compared to a loss on derivatives, net of $24.4 million in the third quarter of 2017 and an increase in

our depreciation, depletion and amortization (“DD&A”) expense of $12.5 million to $80.1 million for the third quarter of 2018 as compared to $67.6 million for the third quarter of 2017. See “—Results of Operations” below for further details.
Recent Developments
In October 2018, we delivered a notice of conditional redemption to the trustee for our 7.50% Senior Notes to call for redemption on November 19, 2018, the remaining $130.0 million aggregate principal amount of outstanding 7.50% Senior Notes at a redemption price of 100% of par, plus accrued and unpaid interest. Our redemption obligation was conditioned on and subject to there being made available to us under the revolving credit facility a commitment amount of at least $1.1 billion as of November 19, 2018, which was satisfied on October 29, 2018 in connection with the amendment to the credit agreement discussed below, therefore, our redemption obligation is no longer conditional. As a result of the redemption, we expect to record a loss on extinguishment of debt of approximately $0.8 million, which is solely attributable to the write-off of unamortized premium and debt issuance costs. Additionally, upon redemptionfirst annual settlement of the 7.50% Senior Notes,Contingent ExL Consideration and received $10.0 million from the May 4, 2022 maturity datefirst annual settlements of the credit agreement will no longer be subject to a springing maturity date of June 15, 2020.Contingent Niobrara Consideration and the Contingent Utica Consideration as the specified pricing thresholds for fiscal year 2018 for each contingent consideration arrangement were exceeded. See “Note 12. Derivative Instruments” for further discussion.
In October 2018,March 2019, we entered into the thirteenthfourteenth amendment to our credit agreement governing the revolving credit facility to, among other things (i) establish the borrowing base at $1.3$1.35 billion, with an elected commitment amount of $1.1$1.25 billion, until the next redetermination thereof, (ii) reduce the applicable margins for Eurodollar loans from 1.50%-2.50% to 1.25%-2.25% and base rate loans from 0.50%-1.50% to 0.25%-1.25%, each depending on the level of facility usage and each subject to an increase of 0.25% for any period during which the ratio of Total Debt to EBITDA exceeds 3.00 to 1.00, (iii) amend the definition of Capital Leases,Current Ratio, and (iv)(iii) amend certain other definitions and provisions.
We recorded net income attributable to common shareholders for the three months ended March 31, 2019 of $146.2 million, or $1.58 per diluted share, as compared to net income attributable to common shareholders for the three months ended March 31, 2018 of $14.7 million, or $0.18 per diluted share. The increase in net income attributable to common shareholders was driven primarily by an income tax benefit of approximately $179.4 million as a result of a release of a substantial portion of our deferred tax asset valuation allowance during the first quarter of 2019, partially offset by a $53.7 million increase in our loss on derivatives, net to $83.3 million for the first quarter of 2019 as compared to $29.6 million for the first quarter of 2018.

The increase in lease operating expenses is primarily due to costs associated with increased production. The increasedecrease in lease operating expense per Boe is primarily due to processing fees for certainthe divestiture in the Eagle Ford in the first quarter of our natural gas and NGL processing contracts that, effective January 1, 2018, are presented in leasewhich carried higher per Boe operating expenses as a result of the adoption of ASC in 606. This more than offset a net decrease in lease operating expense per Boe relatedcompared to the change in theour remaining Eagle Ford properties, as well as an increased proportion of production from wells drilled on properties acquired in the ExL Acquisition, which have lower operating costs per Boe than our other Delaware Basin and Eagle Ford properties, and the increased proportion of total production from crude oil properties, as a result of the divestiture in Marcellus in the fourth quarter of 2017, which have a higher per operating cost per Boe than natural gas properties.

Production and ad valorem taxes increased to $14.5 million (4.8% of revenues)
The following table summarizes production and ad valorem taxes for the three months ended September 30, 2018 from $7.7 million (4.3% of revenues) for the same period in 2017 primarily as a result of the increase in crude oil and NGL revenues. periods indicated:

The increase in production and ad valorem taxes, as well as the increase of production and ad valorem taxes as a percentagepercent of revenues, is primarily due to the divestiture of substantially all of our assets in Marcellus in the fourth quarter of 2017, as our production in Marcellus was not subject to production taxes.
Ad valorem taxes increased to $2.6 million (0.9% of revenues) for the three months ended September 30, 2018 from $1.7 million (1.0% of revenues) for the same period in 2017. The increase in ad valorem taxes is due toas a result of new wells drilled in the Eagle Ford and Delaware Basin and higher property tax valuations as a result of the increase in crude oil prices partially offset by a reduction in ad valorem taxes resulting fromduring 2018.
Depreciation, depletion and amortization
The following table sets forth the divestitures discussed above. The decrease in ad valorem taxes as a percentagecomponents of revenues is primarily due toour depreciation, depletion and amortization (“DD&A”) expense for the timing of when wells are included in the ad valorem tax assessment as wells drilled and producing during 2018 would not be included in ad valorem tax assessment until 2019.periods indicated:

The effectiveFor the first quarter of 2019, we recognized an income tax rates for the third quarterbenefit of 2018 and 2017 were 1.1% and 0.0%, respectively, which were nominal$179.4 million as a result of maintainingdetermining that it was more likely than not that our deferred tax assets would be realized after considering all available evidence (both positive and negative). A significant item of objective positive evidence considered was the cumulative pre-tax income incurred over the three-year period ended March 31, 2019. As a fullresult, we released $179.1 million of the valuation allowance against our net deferred tax assets. The increaseassets which resulted in an income tax benefit.

For the effective rate between the periods is due to $0.9first quarter of 2018, we recognized income tax expense of $0.3 million of Texas franchise tax recognized for the three months ended September 30, 2018 due to an increase in the apportionment of income to the state of Texas as a result of our divestitures in the fourth quarter of 2017 and first quarter of 2018.
Throughout 2017 and the first nine months of 2018, we maintainedmaintaining a full valuation allowance against our deferred tax assets based on our conclusion considering all available evidence (both positive and negative), that it was more likely than not that the deferred tax assets would not be realized. A significant item of objective negative evidence considered was the cumulative pre-tax loss incurred over the three-year period ended September 30,March 31, 2018, primarily due to impairments of proved oil and gas properties recognized in the fourth quarter of 2015 and the first three quarters of 2016, which limitslimited our ability to consider subjective positive evidence, such as its projections of future taxable income.
We currently believes it is reasonably possible for us to achieve a three-year cumulative level of profitability within the next 12 months, and considering the rebound in crude oil prices during 2018 and improved outlook for 2019, would enhance our ability to conclude that it is more likely than not that the deferred tax assets would be realized and support a release of a portion or substantially all of the valuation allowance. A release of the valuation allowance would result in the recognition of an increase in deferred tax assets and an income tax benefit in the period in which the release occurs, although the exact timing and amount of the release is subject to change basedDividends on numerous factors, including our projections of future taxable income, which we continue to assess based on available information each reporting period.preferred stock
For the three months ended September 30,March 31, 2019 and 2018, and 2017, we declared, and paid in cash, dividends of $4.5$4.4 million and $2.2$4.9 million, respectively, on our Preferred Stock.

Production volumes for the nine months ended September 30, 2018 were 57,703 Boe/d, an increase of 13% from 50,902 Boe/d for the same period in 2017. The increase is primarily due to production from new wells in the Delaware Basin, primarily drilledLoss on properties from the ExL Acquisition, as well as in Eagle Ford, partially offset by the divestitures in Utica and Marcellus in the fourth quarter of 2017 and Niobrara and Eagle Ford in the first quarter of 2018. Revenues for the nine months ended September 30, 2018 increased 59% to $792.6 million from $499.1 million for the same period in 2017 primarily due to higher crude oil prices and higher crude oil production.
Lease operating expenses for the nine months ended September 30, 2018 increased to $115.4 million ($7.33 per Boe) from $100.8 million ($7.25 per Boe) for the same period in 2017. The increase in lease operating expenses is primarily due to costs associated with increased production. The increase in lease operating expense per Boe is primarily due to processing fees for certain of our natural gas and NGL processing contracts that, effective January 1, 2018, are presented in lease operating expenses as a result of the adoption of ASC in 606. Additionally, there was a net increase in lease operating expense per Boe related to the increased proportion of total production from crude oil properties, which have a higher operating cost per Boe than natural gas properties, as a result of the divestiture in Marcellus in the fourth quarter of 2017 and the increased proportion of production from properties acquired in the ExL Acquisition, which have lower operating costs per Boe than our other Delaware Basin and Eagle Ford properties.
Production taxes increased to $37.6 million (or 4.7% of revenues) for the nine months ended September 30, 2018 from $21.1 million (or 4.2% of revenues) for the same period in 2017 primarily as a result of the increase in crude oil and NGL revenues. The

increase in production taxes as a percentage of revenues is due to the divestiture of substantially all of our assets in Marcellus in the fourth quarter of 2017, as our production in Marcellus was not subject to production taxes.
Ad valorem taxes increased to $8.2 million (1.0% of revenues) for the nine months ended September 30, 2018 from $5.8 million (1.2% of revenues) for the same period in 2017. The increase in ad valorem taxes is due to new wells drilled in the Eagle Ford and new wells drilled or acquired in the Delaware Basin and higher property tax valuations as a result of the increase in crude oil prices, partially offset by a reduction in ad valorem taxes resulting from the divestitures discussed above. The decrease in ad valorem taxes as a percentage of revenues is primarily due to the timing of when wells are included in the ad valorem tax assessment as wells drilled and producing during 2018 would not be included in ad valorem tax assessment until 2019.
DD&A expense for the nine months ended September 30, 2018 increased $36.0 million to $217.0 million ($13.78 per Boe) from $181.0 million ($13.03 per Boe) for the same period in 2017. The increase in DD&A expense is attributable to increased production as well as an increase in the DD&A rate per Boe. The increase in the DD&A rate per Boe is due primarily to increases in future development costs that occurred subsequent to the third quarter of 2017 as well as an increase to proved oil and gas properties as a result of our ongoing capital expenditure program, partially offset by the reduction in proved oil and gas properties as a result of the divestitures in Utica and Marcellus in the fourth quarter of 2017 and Niobrara and Eagle Ford in the first quarter of 2018 and an increase in proved oil and gas reserves. The components of our DD&A expense were as follows:

General and administrative expense, net increased to $58.4 million for the nine months ended September 30, 2018 from $49.3 million for the same period in 2017. The increase was primarily due to an increase in stock-based compensation expense, net as a result of an increase in the fair value of stock appreciation rights for the nine months ended September 30, 2018 compared to a decrease in fair value for the nine months ended September 30, 2017 as well as an increase in personnel costs and higher annual bonuses awarded in the first quarter of 2018 compared to the first quarter of 2017.
We recorded a loss on derivatives, net of $152.7 million and a gain on derivatives, net of $27.0 million for the nine months ended September 30, 2018 and 2017, respectively. The components of our (gain) loss on derivatives, net were as follows:

Interest expense, net for the nine months ended September 30, 2018 was $46.5 million as compared to $62.4 million for the same period in 2017. The decrease was due primarily to reduced interest expense as a result of the redemptions of the 7.50% Senior Notes in the fourth quarter of 2017 and first quarter of 2018 as well as an increase in capitalized interest as a result of higher

average balances of unevaluated leasehold and seismic costs over the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017, primarily as a result of the ExL Acquisition in the third quarter of 2017. The decrease was partially offset by interest expense on $250.0 million aggregate principal amount of our 8.25% Senior Notes that were issued in the third quarter of 2017 and increased borrowings and associated interest expense on our revolving credit facility for the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017.

As a result of our redemption of $320.0 million aggregate principal amount of our 7.50% Senior Notes, we recorded a loss on extinguishment of debt of $8.7 million for the nine months ended September 30, 2018, which included redemption premiums of $6.0 million paid to redeem the notes and non-cash charges of $2.7 million attributable to the write-off of unamortized premium and debt issuance costs.
The effective income tax rate for the nine months ended September 30, 2018 and 2017 was 1.2% and 0.0%, respectively, which were nominal as a result of maintaining a full valuation allowance against our net deferred tax assets. The increase in the effective rate between the periods is due to $1.7 million of Texas franchise tax recognized for the nine months ended September 30, 2018 due to an increase in the apportionment of income to the state of Texas as a result of our divestitures in the fourth quarter of 2017 and first quarter of 2018.
Throughout 2017 and the first nine months of 2018, we maintained a full valuation allowance against our deferred tax assets based on our conclusion, considering all available evidence (both positive and negative), that it was more likely than not that the deferred tax assets would not be realized. A significant item of objective negative evidence considered was the cumulative pre-tax loss incurred over the three-year period ended September 30, 2018, primarily due to impairments of proved oil and gas properties recognized in the fourth quarter of 2015 and the first three quarters of 2016, which limits our ability to consider subjective positive evidence, such as its projections of future taxable income.
We currently believe it is reasonably possible for us to achieve a three-year cumulative level of profitability within the next 12 months, and considering the rebound in crude oil prices during 2018 and improved outlook for 2019, would enhance our ability to conclude that it is more likely than not that the deferred tax assets would be realized and support a release of a portion or substantially all of the valuation allowance. A release of the valuation allowance would result in the recognition of an increase in deferred tax assets and an income tax benefit in the period in which the release occurs, although the exact timing and amount of the release is subject to change based on numerous factors, including our projections of future taxable income, which we continue to assess based on available information each reporting period.
For the nine months ended September 30, 2018 and 2017, we declared and paid cash dividends of $13.8 million and $2.2 million, respectively, on our Preferred Stock.preferred stock
During the first quarter of 2018, we redeemed 50,000 shares of Preferred Stock, representing 20% of the issued and outstanding Preferred Stock, for $50.5 million, consisting of the $50.0 million redemption price and $0.5 million accrued and unpaid dividends.dividends of $0.5 million. We recognized a $7.1 million loss on the redemption due to the excess of the $50.0 million redemption price over the $42.9 million redemption date carrying value of the Preferred Stock.

2018 Drilling, Completion, and Infrastructure2019 DC&I Capital Expenditure Plan and Funding Strategy. Our 2018 drilling, completion, and infrastructure2019 DC&I capital expenditure plan remains unchanged at $800.0$525.0 million to $825.0$575.0 million. We currently intend to finance the remainder of our 2018 drilling, completion, and infrastructure2019 DC&I capital expenditure plan primarily from the sources described below under “—Sources and Uses of Cash.” Our capital program could vary depending upon various factors, including, but not limited to, the availability of drilling rigs and completion crews, the cost of completion services, acquisitions and divestitures of oil and gas properties, land and industry partner issues, our available cash flow and financing, success of drilling programs, weather

delays, commodity prices, market conditions, the acquisition of leases with drilling commitments and other factors. The following is a summary of our capital expenditures for the three and nine months ended September 30, 2018March 31, 2019:

Sources and Uses of Cash. Our primary use of cash is related to our drilling, completion and infrastructureDC&I capital expenditures and, to a lesser extent, our leasehold and seismic capital expenditures. For the ninethree months ended September 30, 2018,March 31, 2019, we funded our capital expenditures primarily with cash provided by operations and borrowings under our revolving credit facility. Potential sources of future liquidity include the following:
Cash provided by operations. Cash flows from operations are highly dependent on crude oil prices. As such, we hedge a portion of our forecasted production to reduce our exposure to commodity price volatility in order to achieve a more predictable level of cash flows.
Borrowings under revolving credit facility. As of November 2, 2018,April 30, 2019, our revolving credit facility had a borrowing base of $1.3$1.35 billion, with an elected commitment amount of $1.1$1.25 billion, with $618.0$901.9 million of borrowings outstanding. The amount we are able to borrow is subject to compliance with the financial covenants and other provisions of the credit agreement governing our revolving credit facility. See “Note 14. Subsequent Events” for details of the recent thirteenth amendment.
Securities offerings. As situations or conditions arise, we may choose to issue debt, equity or other securities to supplement our cash flows. However, we may not be able to obtain such financing on terms that are acceptable to us, or at all. See “Note 9. Shareholders’ Equity and Stock-Based Compensation” for details regarding the recent common stock offering.

Divestitures. We may consider divesting certain properties or assets that are not part of our core business or are no longer deemed essential to our future growth, provided we are able to divest such assets on terms that are acceptable to us. See “Note 3. Acquisitions and Divestitures of Oil and Gas Properties” for further details.
Joint ventures. Joint ventures with third parties through which such third parties fund a portion of our exploration activities to earn an interest in our exploration acreage or purchase a portion of interests, or both.
Overview of Cash Flow Activities. Net cash provided by operating activities was $465.3$125.1 million and $280.6$138.7 million for the ninethree months ended September 30,March 31, 2019 and 2018, and 2017, respectively. The increasedecrease was driven primarily by an increase in working capital requirements and operating expenses as well as a decrease in revenues as a result of lower crude oil and NGL prices, partially offset by an increase in revenues as a result of higher crude oil prices and higher crude oilNGL production partially offset by an increaseand a decrease in the net cash paid for derivative settlements and an increase in operating expenses and cash general and administrative expense.settlements.
Net cash used in investing activities decreased to $309.0was $160.6 million for the ninethree months ended September 30, 2018, from $1,105.0March 31, 2019 as compared to net cash provided by investing activities was $107.6 million for the corresponding period in 2017. This2018. The change was primarily due primarily to the proceeds we received in the first quarter of 2018 related to the divestitures in Eagle Ford and Niobrara, partially offset by a decrease in cash paymentspaid for acquisitions of oil and gas properties, as well ascapital expenditures.
Net cash received fromprovided by financing activities was $35.4 million for the divestitures in Niobrara and Eagle Ford in early 2018, partially offset by an increase in capital expenditures as a result of our ongoing drilling, completion, and infrastructure activity in Eagle Ford and the Delaware Basin.
Netthree months ended March 31, 2019 compared to net cash used in financing activities was $163.5 million for the ninethree months ended September 30,March 31, 2018 compared to net cash provided by financing activities for the nine months ended September 30, 2017 of $825.3$251.0 million. The change was primarily due to payments for the redemptions of our 7.50% Senior Notes and Preferred Stock during the first quarter of 2018 and decreased borrowings, net of repayments under our revolving credit facility decreasedduring the first quarter of 2019, partially offset by net cash provided by the issuancepaid for settlements of senior notes and preferred stock, and increased cash dividends paid on the Preferred Stock.

contingent consideration arrangements in January 2019.
Liquidity/Cash Flow Outlook. Economic downturns may adversely affect our ability to access capital markets in the future. Cash flows from operations are primarily driven by crude oil production, crude oil prices, and settlements of our crude oil derivatives. We currently believe that cash flows from operations and borrowings under our revolving credit facility will provide adequate financial flexibility and will be sufficient to fund our immediate cash flow requirements.
Revolving credit facility. The borrowing base under our revolving credit facility is affected by assumptions of the administrative agent with respect to, among other things, crude oil and, to a lesser extent, natural gas prices. Our borrowing base may decrease if our administrative agent reduces the crude oil and natural gas prices from those used to determine our existing borrowing base. See “Note 7. Long-Term Debt” and “—Sources and Uses of Cash—Borrowings under revolving credit facility” and “—Financing Arrangements—Senior Secured Revolving Credit Facility” for further details of our revolving credit facility.
Contingent consideration arrangements. As part of the ExL Acquisition, as well as in each of the divestitures of our assets in Niobrara, Marcellus, and Utica, we agreed to contingent consideration arrangements, where we will receive or be required to pay certain amounts if commodity prices are greater than specified thresholds. See “Note 10.12. Derivative Instruments” for further details of each of these contingent consideration arrangements and “Item 3. Quantitative and Qualitative Disclosures About Market Risk” for details of the sensitivities to commodity price for each contingent consideration arrangement.
Commodity derivative instruments. We use commodity derivative instruments to mitigate the effects of commodity price volatility for a portion of our forecasted sales of production and achieve a more predictable level of cash flow.

If cash flows from operations and borrowings under our revolving credit facility and the other sources of cash described under “—Sources and Uses of Cash” are insufficient to fund our remaining 2019 DC&I capital expenditure plan, we may need to reduce our capital expenditure plan or seek other financing alternatives. We may not be able to obtain financing needed in the future on terms that would be acceptable to us, or at all. If we cannot obtain adequate financing, we may be required to limit or defer a portion of our remaining 2019 DC&I capital expenditure plan, thereby potentially adversely affecting the recoverability and ultimate value of our oil and gas properties. Based on existing market conditions and our expected liquidity needs, among other factors, we may use a portion of our cash flows from operations, proceeds from divestitures, securities offerings or borrowings to reduce debt prior to scheduled maturities through debt repurchases, either in the open market or in privately negotiated transactions, through debt redemptions or tender offers, or through repayments of bank borrowings. See “Note 14. Subsequent Events” for details of the notice of conditional redemption for the remaining $130.0 million aggregate principal amount of outstanding 7.50% Senior Notes.

(1)Long-term debt consists of the principal amounts of the 7.50% Senior Notes due 2020, the 6.25% Senior Notes due 2023, the 8.25% Senior Notes due 2025, and borrowings outstanding under our revolving credit facility which matures in 2022 (subject to a springing maturity date of June 15, 2020 if the 7.50% Senior Notes have not been redeemed or refinanced on or prior to such time). Subsequent to September 30, 2018, we delivered a notice of conditional redemption to the trustee for our 7.50% Senior Notes to call for redemption the remaining $130.0 million aggregate principal amount of our outstanding 7.50% Senior Notes due 2020, which was satisfied on October 29, 2018 in connection with entering into the thirteenth amendment to our credit agreement governing our revolving credit facility. See “Note 14. Subsequent Events” for further details.2022.
(2)Cash interest on senior notes includes cash payments for interest on the 7.50% Senior Notes due 2020, the 6.25% Senior Notes due 2023 and the 8.25% Senior Notes due 2025.
(3)Cash interest on our revolving credit facility was calculated using the weighted average interest rate of the outstanding borrowings under the revolving credit facility as of September 30, 2018March 31, 2019 of 3.87%4.18%. Commitment fees on our revolving credit facility were calculated based on the unused portion of lender commitments as of September 30, 2018,March 31, 2019, at the applicable commitment fee rate of 0.375%0.500%.
(4)Drilling rigOther operating leases include contracts for office space and the use of well equipment, vehicles, and other office equipment. The amounts presented above represent gross contractual obligations and accordingly, otherobligations. Other joint owners in the properties operated by us will generally be billedpay for their working interest share of costs associated with the use of well equipment.
(5)Drilling rig contracts represent gross contractual obligations. Other joint owners in the properties operated by us generally pay for their working interest share of such costs.
(5)(6)Delivery commitments represent contractual obligations we have entered into for certain gathering, processing and transportation service agreements which require minimum volumes of natural gas to be delivered. The amounts in the table above reflect the aggregate undiscounted deficiency fees assuming no delivery of any natural gas.
(6)(7)Produced water disposal commitments represent contractual obligations we have entered into for certain service agreements which require minimum volumes of produced water to be delivered. The amounts in the table above reflect the aggregate undiscounted deficiency fees assuming no delivery of any produced water.
(7)(8)
Asset retirement obligations and other are based on estimates and assumptions that affect the reported amounts as of September 30, 2018March 31, 2019. Certain of such estimates and assumptions are inherently unpredictable and will differ from actual results.
(8)In connection with the ExL Acquisition, we have agreed to a contingent payment of $50.0 million per year if crude oil prices exceed specified thresholds for each of the years of 2018 through 2021 with a cap of $125.0 million, which is not included in the table above.
FinancingOff Balance Sheet Arrangements
Senior Secured Revolving Credit Facility
We currently have a senior secured revolving credit facility with a syndicate of banks that, as of September 30, 2018, had a borrowing base of $1.0 billion, with an elected commitment amount of $900.0 million, and $309.8 million of borrowings outstanding at a weighted average interest rate of 3.87%. The credit agreement governing our senior secured revolving credit facility provides for interest-only payments until May 4, 2022, when the credit agreement matures (subject to a springing maturity date of June 15, 2020 if the 7.50% Senior Notes have not been redeemed or refinanced on or prior to such time) and any outstanding borrowings are due. Upon redemption of the 7.50% Senior Notes discussed below, the May 4, 2022 maturity date of the credit agreement will no longer be subject to a springing maturity date of June 15, 2020.
On January 31, 2018, as a result of the divestiture in the Eagle Ford Shale, the borrowing base under the senior secured revolving credit facility was reduced from $900.0 million to $830.0 million, however, the elected commitment amount remained unchanged at $800.0 million.
On May 4, 2018, we entered into the twelfth amendment to the credit agreement governing the revolving credit facility to, among other things, increase the borrowing base and elected commitment amount, reduce the margins applied to Eurodollar and base rate

loans, and amend the covenant limiting payment of dividends and distributions on equity to increase our ability to make dividends and distributions on our equity interests. See “Note 6. Long-Term Debt” for further details.
On October 29, 2018, we entered into the thirteenth amendment to the credit agreement governing the revolving credit facility to, among other things, increase the borrowing base and elected commitment amount and reduce the margins applied to Eurodollar and base rate loans. See “Note 14. Subsequent Events” for further details.
See “Note 6. Long-Term Debt” for details of rates of interest on outstanding borrowings, commitment fees on the unused portion of lender commitments, and the financial covenants we are subject to under the terms of the credit agreement as of September 30, 2018.
7.50% Senior Notes
During the first quarter of 2018, we redeemed $320.0 million of the outstanding aggregate principal amount of our 7.50% Senior Notes at a price equal to 101.875% of par. Upon the redemptions, we paid $336.9 million, which included redemption premiums of $6.0 million as well as accrued but unpaid interest of $10.9 million. As a result of the redemptions, we recorded a loss on extinguishment of debt of $8.7 million, which included the redemption premiums $6.0 million paid to redeem the notes and non-cash charges of $2.7 million attributable to the write-off of unamortized premium and debt issuance costs.
On October 18, 2018, we delivered a notice of conditional redemption to the trustee for our 7.50% Senior Notes to call for redemption on November 19, 2018, the remaining $130.0 million aggregate principal amount of the outstanding 7.50% Senior Notes at a redemption price of 100% of par, plus accrued and unpaid interest. The redemption obligation was conditioned on and subject to there being made available to us under our revolving credit facility a commitment amount of at least $1.1 billion as of November 19, 2018, which was satisfied on October 29, 2018 in connection with the amendment to the credit agreement discussed above, therefore, our redemption obligation is no longer conditional. See “Note 14. Subsequent Events” for further details.
Redemption of Preferred Stock
During the first quarter of 2018, we redeemed 50,000 shares of Preferred Stock, representing 20% of the issued and outstanding Preferred Stock, for $50.5 million, consisting of the $50.0 million redemption price and $0.5 million accrued and unpaid dividends. We recognized a $7.1 million loss on the redemption due to the excess of the $50.0 million redemption price over the $42.9 million redemption date carrying value of the Preferred Stock.
Redemption of Other Long-Term Debt
During the second quarter of 2018, we redeemed the remaining $4.4 million outstanding principal amount of our 4.375% Convertible Senior Notes due 2028 at a price equal to 100% of par. Upon redemption, we paid $4.5 million, which included accrued and unpaid interest of $0.1 million.off balance sheet arrangements.
Critical Accounting Policies
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods reported. Certain of such estimates and assumptions are inherently unpredictable and will differ from actual results. We have identified the following critical accounting policies and estimates used in the preparation of our financial statements: use of estimates, oil and gas properties, oil and gas reserve estimates, derivative instruments, contingent consideration arrangements, income taxes, commitments and contingencies and preferred stock. These policies and estimates are described in “Note 2. Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in our 20172018 Annual Report. See “Note 8.9. Preferred Stock”Stock and Common Stock Warrants”, “Note 10.12. Derivative Instruments” and “Note 11.13. Fair Value Measurements” for details of the Preferred Stock and contingent consideration arrangements. We evaluate subsequent events through the date the financial statements are issued.

The table below presents various pricing scenarios to demonstrate the sensitivity of our September 30, 2018March 31, 2019 cost center ceiling to changes in the 12-month average benchmark crude oil and natural gas prices underlying the average realized prices for sales of crude oil, NGLs, and natural gas on the first calendar day of each month during the 12-month period prior to the end of the current quarter (“12-Month Average Realized Price”). The sensitivity analysis is as of September 30, 2018March 31, 2019 and, accordingly, does not consider

drilling and completion activity, acquisitions or divestitures of oil and gas properties, production, changes in crude oil and natural gas prices, and changes in development and operating costs occurring subsequent to September 30, 2018March 31, 2019 that may require revisions to estimates of proved reserves.

The price of crude oil, which is the commodity price that our cost center ceiling is most sensitive to, increased slightly during the first quarter of 2019 as compared to year end 2018, however, the 12-Month Average Realized Price as of March 31, 2019 decreased when compared to the 12-Month Average Realized Price as of December 31, 2018. We currently estimate that the 12-Month Average Realized Price of crude oil as of June 30, 2019 will be $62.25, which is based on the average realized price for sales of crude oil on the first calendar day of each month for the first 11 months and an estimate for the twelfth month based on a quoted forward price. Utilizing this estimated 12-Month Average Realized Price, we estimate that the second quarter of 2019 cost center ceiling will exceed the net book value, less related deferred income taxes, resulting in no impairment of proved oil and gas properties.
This estimate assumes that all other inputs and assumptions are as of March 31, 2019, other than the price of crude oil, and remain unchanged. As such, drilling and completion activity, acquisitions or dispositions of oil and gas properties, production, and changes in development and operating costs occurring subsequent to March 31, 2019 may require revisions to estimates of proved reserves, which would impact the calculation of the cost center ceiling.
Income Taxes
Income taxes are recognized based on earnings reported for tax return purposes in addition to a provision for deferred income taxes. Deferred income taxes are recognized at the end of each reporting period for the future tax consequences of cumulative temporary differences between the tax bases of assets and liabilities and their reported amounts in our financial statements based on existing tax laws and enacted statutory tax rates applicable to the periods in which the temporary differences are expected to affect taxable income. We assess the realizability of our deferred tax assets on a quarterly basis by considering whether it is more likely than not that all or a portion of the deferred tax assets will not be realized. We consider all available evidence (both positive and negative) when determining whether a valuation allowance is required. In making this assessment, we evaluated possible sources of taxable income that may be available to realize the deferred tax assets, including projected future taxable income, the reversal of existing temporary differences, taxable income in carryback years and available tax planning strategies.
For the year ended December 31, 2018, we maintained a full valuation allowance against our deferred tax assets based on our conclusion, considering all available evidence (both positive and negative), that it was more likely than not that the deferred tax assets would not be realized. A significant item of objective negative evidence considered was the cumulative pre-tax loss incurred over the three-year period ended December 31, 2018, primarily due to impairments of proved oil and gas properties recognized in the first three quarters of 2016, which limited our ability to consider subjective positive evidence, such as its projections of future taxable income. However, as of March 31, 2019, we are in a cumulative pre-tax income position. Based on this factor, as well as other positive evidence including projected future taxable income for the current and future years, concluded that it is more likely than not that the deferred tax assets would be realized. As a result, we released $179.1 million of the valuation allowance, which was recognized as an income tax benefit for the three months ended March 31, 2019.

We will continue to assess the timing and amount of additional releases of the valuation allowance based on available information each reporting period, such as our projections of future taxable income, and currently anticipate that the remaining valuation allowance will be released by December 31, 2019.
As of September 30, 2018,March 31, 2019, we have estimated U.S. federal net operating loss carryforwards of $1.1 billion.$1.1 billion that, if not utilized in earlier periods, will expire between 2026 and 2037. Our ability to utilize these U.S. loss carryforwards to reduce future taxable income is subject to various limitations under the Internal Revenue Code of 1986, as amended (the “Code”). The utilization of such carryforwards may be limited upon the occurrence of certain ownership changes, including the purchase or sale of stock by 5% shareholders and the offering of stock by us during any three-year period resulting in an aggregate change of more than 50% in our beneficial ownership. In the event of an ownership change, Section 382 of the Code imposes an annual limitation on the amount of our taxable income that can be offset by these carryforwards. The limitation is generally equal to the product of (a) the fair market value of our equity multiplied by (b) a percentage approximately equivalent to the yield on long-term tax exempt bonds during the month in which an ownership change occurs. In addition, the limitation is increased if there are recognized built-in gains during any post-change year, but only to the extent of any net unrealized built-in gains inherent in the assets sold.
Due to the issuance of the Preferred Stock and the common stock offering associated with the ExL Acquisition in 2017, as well as the common stock offering in August 2018, our calculated ownership change percentage increased, however,increased. However, as of September 30, 2018,March 31, 2019, we do not believe we have a Section 382 limitation on the ability to utilize our U.S. loss carryforwards. Future equity transactions involving us or 5% shareholders of us (including, potentially, relatively small transactions and transactions beyond our control) could cause further ownership changes and therefore a limitation on the annual utilization of the U.S. loss carryforwards.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
For information regarding our exposure to certain market risks, see “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” in our 20172018 Annual Report. Except as disclosed below, there have been no material changes from the disclosure made in our 20172018 Annual Report regarding our exposure to certain market risks.
Commodity Price Risk
Our revenues, future rate of growth, results of operations, financial position and ability to borrow funds or obtain additional capital are substantially dependent upon prevailing prices of crude oil, NGLs, and natural gas, which are affected by changes in market supply and demand and other factors. The markets for crude oil, NGLs, and natural gas have been volatile, especially over the last several years, and these markets will likely continue to be volatile in the future.

The following tables settable sets forth our crude oil, NGL, and natural gas revenues for the three and nine months ended September 30, 2018March 31, 2019 as well as the impact on the crude oil, NGL, and natural gas revenues assuming a 10% increase and decrease in our average realized crude oil, NGL, and natural gas prices, excluding the impact of derivative settlements:

We use commodity derivative instruments to mitigate the effects of commodity price volatility for a portion of our forecasted sales of production and achieve a more predictable level of cash flow. We do not enter into commodity derivative instruments for speculative purposes. As of September 30, 2018,March 31, 2019, our commodity derivative instruments consisted of price swaps, three-way collars, basis swaps, and sold call options.options, and basis swaps. See “Note 10.12. Derivative Instruments” and “Note 15. Subsequent Events” for further detailsdiscussion of our crude oil, NGL and natural gas commodity derivative instruments as of September 30, 2018March 31, 2019 and “Note 14.

During the three months ended March 31, 2019, we paid $50.0 million as a result of the first annual settlement of the Contingent ExL Consideration and received $10.0 million from the first annual settlements of the Contingent Niobrara Consideration and the Contingent Utica Consideration as the specified pricing thresholds for fiscal year 2018 for each contingent consideration arrangement were exceeded. A 10% increase or decrease in the settlement price would have had no impact on the actual settlements related to our Contingent ExL Consideration, Contingent Niobrara Consideration, and Contingent Utica Consideration. A 10% increase in the settlement price would have resulted in a $3.0 million cash receipt related to our Contingent Marcellus Consideration, while a 10% decrease in the settlement price would have had no impact. See “Note 12. Derivative Instruments” for further details on the cash received (paid) for settlements of contingent consideration arrangements, net.
The primary drivers of our commodity derivative instrument fair values are the underlying forward oil and gas price curves. The following table sets forth the average forward oil and gas price curves as of March 31, 2019 for each of the years in which we have commodity derivative instruments:

The fair values of the contingent consideration arrangements were determined by a third-party valuation specialist using Monte Carlo simulations including significant inputs such as forward oil and gas price curves, volatility factors and risk adjusted discount rates. See “Note 10. Derivative Instruments” and “Note 11.13. Fair Value Measurements” for further details.discussion.

Interest Rate Risk
We are exposed to market risk due to the floating interest rate associated with any outstanding borrowings on our revolving credit facility. Changes in interest rates do not impact the amount of interest we pay on our fixed-rate 7.50% Senior Notes, 6.25% Senior Notes and 8.25% Senior Notes, but can impact their fair values. As of September 30, 2018,March 31, 2019, we had approximately $1.3$1.7 billion of long-term debt outstanding. Of this amount, approximately $1.0$0.9 billion was fixed-rate debt with a weighted average interest rate of 6.89%7.22% and approximately $0.8 billion was floating-rate debt on outstanding borrowings on our revolving credit facility with a weighted average interest rate of 4.18%. A 1% increase or decrease in the interest rate on outstanding borrowings on our revolving credit facility would have a corresponding increase or decrease in our interest expense of approximately $2.1 million. See “Note 11.13. Fair Value Measurements” for further details on the fair value of our 7.50% Senior Notes, 6.25% Senior Notes and 8.25% Senior Notes.

Part II. Other Information
Item 1. Legal Proceedings
From time to time, the Company is party to certain legal actions and claims arising in the ordinary course of business. While the outcome of these events cannot be predicted with certainty, management does not currently expect these matters to have a materially adverse effect on the financial position or results of operations of the Company.
The following disclosure updates the legal proceeding set forth under the heading “Barrow-Shaver Litigation” in the 2017 Annual Report to reflect developments during the three months ended September 30, 2018 and should be read together with the corresponding disclosure in the 2017 Annual Report.
Barrow-Shaver Litigation
On September 24, 2014 an unfavorable jury verdict was delivered against the Company in a case entitled Barrow-Shaver Resources Company v. Carrizo Oil & Gas, Inc. in the amount of $27.7 million. On January 5, 2015, the court entered a judgment awarding the verdict amount plus $2.9 million in attorneys’ fees plus pre-judgment interest. On January 31, 2017, the Twelfth Court of Appeals at Tyler, Texas reversed the trial court decision and rendered judgment in favor of the Company, declaring that the plaintiff take nothing on any of its claims. The plaintiff filed a motion for rehearing with the Twelfth Court of Appeals at Tyler, Texas, which was not granted, and petitioned the Texas Supreme Court for review. In August 2018, the Texas Supreme Court granted review and set oral argument for December 4, 2018. The payment of damages per the original judgment was superseded by posting a bond in the amount of $25.0 million, which will remain outstanding pending resolution of the appeals process (which could take an extended period of time) or agreement of the parties.
The case was filed September 19, 2012 in the 7th Judicial District Court of Smith County, Texas and arises from an agreement between the plaintiff and the Company whereby the plaintiff could earn an assignment of certain of the Company’s leasehold interests in Archer and Baylor counties, Texas for each commercially productive oil and gas well drilled by the plaintiff on acreage covered by the agreement. The agreement contained a provision that the plaintiff had to obtain the Company’s written consent to any assignment of rights provided by such agreement. The plaintiff subsequently entered into a purchase and sale agreement with a third-party purchaser allowing the third-party purchaser to purchase rights in approximately 62,000 leasehold acres, including the rights under the agreement with the Company, for approximately $27.7 million. The plaintiff requested the Company’s consent to make the assignment to the third-party purchaser and the Company refused. The plaintiff alleged that, as a result of the Company’s refusal, the third-party purchaser terminated such purchase and sale agreement. The plaintiff sought damages for breach of contract, tortious interference with existing contract and other grounds in an amount not to exceed $35.0 million plus exemplary damages and attorneys’ fees. As mentioned above, the Twelfth Court of Appeals at Tyler, Texas found in favor of the Company on all grounds.
