OASIS PETROLEUM INC.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization and Operations of the Company

Organization

Oasis Petroleum Inc. (together with its subsidiaries, “Oasis” or the “Company”) was formed on February 25, 2010, pursuant to the laws of the State of Delaware, to become a holding company for Oasis Petroleum LLC (“OP LLC”), the Company’s predecessor, which was formed as a Delaware limited liability company on February 26, 2007. In connection with its initial public offering in June 2010 and related corporate reorganization, the Company acquired all of the outstanding membership interests in OP LLC in exchange for shares of the Company’s common stock. Oasis Petroleum North America LLC (“OPNA”), a Delaware limited liability company formed in 2007, conducts the Company’s domestic oil and natural gas exploration and production activities. In 2011, the Company formed Oasis Well Services LLC (“OWS”), a Delaware limited liability company, to provide well services to OPNA, and Oasis Petroleum Marketing LLC (“OPM”), a Delaware limited liability company, to provide marketing services to OPNA. In 2013, the Company formed Oasis Midstream Services LLC (“OMS”), a Delaware limited liability company, to provide midstream services to OPNA.

Nature of Business

The Company is an independent exploration and production company focused on the acquisition and development of unconventional oil and natural gas resources in the Williston Basin. The Company’s proved and unproved oil and natural gas properties are located in the North Dakota and Montana areas of the Williston Basin and are owned by OPNA. The Company also operates an oil and gas marketing business (OPM), a well services business (OWS) and a midstream services business (OMS), all of which are complementary to its primary development and production activities. Both OWS and OMS are separate reportable business segments, while OPM is included in the Company’s exploration and production segment.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company include the accounts of Oasis and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. The accompanying condensed consolidated financial statements of the Company have not been audited by the Company’s independent registered public accounting firm, except that the Condensed Consolidated Balance Sheet at December 31, 2014 is derived from audited financial statements. Certain reclassifications of prior year balances have been made to conform such amounts to current year classifications. These reclassifications have no impact on net income. In the opinion of management, all adjustments, consisting of normal recurring adjustments necessary for the fair presentation, have been included. Management has made certain estimates and assumptions that affect reported amounts in the condensed consolidated financial statements and disclosures of contingencies. Actual results may differ from those estimates. The results for interim periods are not necessarily indicative of annual results.

These interim financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain disclosures have been condensed or omitted from these financial statements. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete consolidated financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 (“ 2014 Annual Report”).

As an oil and natural gas producer, the Company’s revenue, profitability and future growth are substantially dependent upon the prevailing and future prices for oil and natural gas, which are dependent upon numerous factors beyond its control such as economic, political and regulatory developments and competition from other energy sources. The energy markets have historically been very volatile, and there can be no assurance that oil and natural gas prices will not be subject to wide fluctuations in the future. Crude oil prices declined significantly in the latter part of 2014 and have remained low in 2015. As a result of lower oil prices, the Company has significantly decreased its planned 2015 capital expenditures as compared to 2014 and is currently concentrating its drilling activities in certain areas that are the most economic in the Williston Basin. An extended period of low prices for oil could have a material adverse effect on the Company’s financial position, results of operations, cash flows and quantities of oil and natural gas reserves that may be economically produced.

Significant Accounting Policies

There have been no material changes to the Company’s critical accounting policies and estimates from those disclosed in the 2014 Annual Report.

Table of Contents

Recent Accounting Pronouncements

Revenue recognition. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The objective of ASU 2014-09 is greater consistency and comparability across industries by using a five-step model to recognize revenue from customer contracts. ASU 2014-09 also contains some new disclosure requirements under GAAP and is effective for interim and annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the effect that adopting this new guidance will have on its financial position, cash flows and results of operations.

Going concern. In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements - Going Concern (“ASU 2014-15”). ASU 2014-15 codifies in GAAP management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for interim and annual reporting periods beginning after December 15, 2016. The Company does not expect the adoption of this guidance to have a material impact on its financial position, cash flows or results of operations.

Extraordinary items. In January 2015, the FASB issued Accounting Standards Update No. 2015-01, Income Statement - Extraordinary and Unusual Items (“ASU 2015-01”). ASU 2015-01 removes the concept of extraordinary items from GAAP. Under existing guidance, an entity is required to separately disclose extraordinary items, net of tax, in the income statement after income from continuing operations if an event or transaction is of an unusual nature and occurs infrequently. This separate, net-of-tax presentation will no longer be allowed. ASU 2015-01 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material impact on its financial position, cash flows or results of operations.

Debt issuance costs. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of debt discount, but it does not affect the recognition or measurement of debt issuance costs. ASU 2015-03 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material impact on its financial position, cash flows or results of operations.

3. Inventory

Equipment and materials consist primarily of proppant, chemicals, tubular goods, well equipment to be used in future drilling or repair operations and well fracturing equipment. Crude oil inventory includes oil in tank and linefill. Inventory is stated at the lower of cost or market value with cost determined on an average cost method. Inventory consists of the following:

(1)	Included in the Company’s proved oil and gas properties are estimates of future asset retirement costs of $38.2 million and $36.9 million at June 30, 2015 and December 31, 2014 , respectively.

Impairment. As a result of expiring leases and periodic assessments of unproved properties, the Company recorded non-cash impairment charges on its unproved oil and natural gas properties of $19.5 million and $24.8 million for the three and six months ended June 30, 2015 , respectively, and $42,000 and $0.8 million for the three and six months ended June 30, 2014 , respectively. The impairment charges for the three and six months ended June 30, 2015 included $19.1 million and $20.3 million , respectively, related to acreage expiring within the next 12 months because there were no current plans to drill or extend the leases prior to their expiration. For the three and six months ended June 30, 2014 , the Company did not record similar impairment charges based on its ability to actively manage and prioritize its capital expenditures to drill leases and to make payments to extend leases that would have otherwise expired. No impairment charges on proved oil and gas properties were recorded for the three and six months ended June 30, 2015 or 2014 .

Divestiture. On March 5, 2014, the Company completed the sale of certain non-operated properties in and around its Sanish position for cash proceeds of approximately $324.9 million , which includes customary post close adjustments. The Company recognized a $187.0 million gain on sale of properties in its Consolidated Statement of Operations for the year ended December 31, 2014.

5. Fair Value Measurements

In accordance with the FASB’s authoritative guidance on fair value measurements, the Company’s financial assets and liabilities are measured at fair value on a recurring basis. The Company recognizes its non-financial assets and liabilities, such as asset retirement obligations (“ARO”) and proved oil and natural gas properties upon impairment, at fair value on a non-recurring basis.

As defined in the authoritative guidance, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). To estimate fair value, the Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable.

The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (“Level 1” measurements) and the lowest priority to unobservable inputs (“Level 3” measurements). The three levels of the fair value hierarchy are as follows:

Level 1 — Unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Pricing inputs, other than unadjusted quoted prices in active markets included in Level 1, are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current market

Table of Contents

and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument and can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 — Pricing inputs are generally less observable from objective sources, requiring internally developed valuation methodologies that result in management’s best estimate of fair value.

Financial Assets and Liabilities

As required, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The following tables set forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis:



	At fair value as of June 30, 2015
	Level 1		Level 2		Level 3		Total
	(In thousands)
Assets:
Money market funds	$	742	$	—	$	—	$	742
Commodity derivative instruments (see Note 6)	—		109,819		—		109,819
Total assets	$	742	$	109,819	$	—	$	110,561

	At fair value as of December 31, 2014
	Level 1		Level 2		Level 3		Total
	(In thousands)
Assets:
Money market funds	$	742	$	—	$	—	$	742
Commodity derivative instruments (see Note 6)	—		315,507		—		315,507
Total assets	$	742	$	315,507	$	—	$	316,249

The Level 1 instruments presented in the tables above consist of money market funds included in cash and cash equivalents on the Company’s Condensed Consolidated Balance Sheet at June 30, 2015 and December 31, 2014 . The Company’s money market funds represent cash equivalents backed by the assets of high-quality major banks and financial institutions. The Company identifies the money market funds as Level 1 instruments because the money market funds have daily liquidity, quoted prices for the underlying investments can be obtained, and there are active markets for the underlying investments.

The Level 2 instruments presented in the tables above consist of commodity derivative instruments, which include oil collars, swaps and deferred premium puts. The fair values of the Company’s commodity derivative instruments are based upon a third-party preparer’s calculation using mark-to-market valuation reports provided by the Company’s counterparties for monthly settlement purposes to determine the valuation of its derivative instruments. The Company has the third-party preparer evaluate other readily available market prices for its derivative contracts, as there is an active market for these contracts. The third-party preparer performs its independent valuation using a moment matching method similar to Turnbull-Wakeman for Asian options. The significant inputs used are crude oil prices, volatility, skew, discount rate and the contract terms of the derivative instruments. However, the Company does not have access to the specific proprietary valuation models or inputs used by its counterparties or third-party preparer. The Company compares the third-party preparer’s valuation to counterparty valuation statements, investigating any significant differences, and analyzes monthly valuation changes in relation to movements in crude oil forward price curves. The determination of the fair value for derivative instruments also incorporates a credit adjustment for non-performance risk, as required by GAAP. The Company calculates the credit adjustment for derivatives in a net asset position using current credit default swap values for each counterparty. The credit adjustment for derivatives in a net liability position is based on the Company’s market credit spread. Based on these calculations, the Company recorded an adjustment to reduce the fair value of its net derivative asset by $0.1 million and $0.6 million at June 30, 2015 and December 31, 2014 , respectively.

Fair Value of Other Financial Instruments

The Company’s financial instruments, including certain cash and cash equivalents, accounts receivable and accounts payable, are carried at cost, which approximates fair value due to the short-term maturity of these instruments. At June 30, 2015 , the Company’s cash equivalents were all Level 1 assets.

The carrying amount of the Company’s long-term debt reported in the Condensed Consolidated Balance Sheet at June 30, 2015 was $2,355.0 million , which includes $2,200.0 million of senior unsecured notes and $155.0 million of borrowings under the revolving credit facility (see Note 7 – Long-Term Debt). The fair value of the Company’s senior unsecured notes, which are publicly traded and therefore categorized as Level 1 liabilities, was $2,218.0 million at June 30, 2015 .

Non-Financial Assets and Liabilities

Asset retirement obligations. The carrying amount of ARO in the Company’s Condensed Consolidated Balance Sheet at June 30, 2015 was $44.9 million (see Note 8 – Asset Retirement Obligations). The Company determines its ARO by calculating the present value of estimated cash flows related to the liability. Estimating the future ARO requires management to make estimates and judgments regarding the timing and existence of a liability, as well as what constitutes adequate restoration when considering current regulatory requirements. Inherent in the fair value calculation are numerous assumptions and judgments, including the ultimate costs, inflation factors, credit adjusted discount rates, timing of settlement and changes in the legal, regulatory, environmental and political environments. These assumptions represent Level 3 inputs. To the extent future revisions to these assumptions impact the fair value of the existing ARO liability, a corresponding adjustment is made to the related asset.

Impairment. The Company reviews its proved oil and natural gas properties for impairment whenever events and circumstances indicate that a decline in the recoverability of their carrying value may have occurred. The Company estimates the expected undiscounted future cash flows of its proved oil and natural gas properties then compares such undiscounted future cash flows to the carrying amount of the proved oil and natural gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company will adjust the carrying amount of the oil and natural gas properties to fair value. The factors used to determine fair value are subject to management’s judgment and expertise and include, but are not limited to, recent sales prices of comparable properties, the present value of future cash flows, net of estimated operating and development costs using estimates of proved reserves, future commodity pricing, future production estimates, anticipated capital expenditures and various discount rates commensurate with the risk and current market conditions associated with realizing the expected cash flows projected. These assumptions represent Level 3 inputs. No impairment charges on proved oil and natural gas properties were recorded for the three and six months ended June 30, 2015 or 2014 .

6. Derivative Instruments

The Company utilizes derivative financial instruments to manage risks related to changes in oil prices. As of June 30, 2015 , the Company utilized two-way costless collar options, swaps and deferred premium puts to reduce the volatility of oil prices on a significant portion of its future expected oil production. A two-way collar is a combination of options: a sold call and a purchased put. The purchased put establishes a minimum price (floor) and the sold call establishes a maximum price (ceiling) the Company will receive for the volumes under contract. A swap is a sold call and a purchased put established at the same price (both ceiling and floor). For the deferred premium puts, the Company agrees to pay a premium to the counterparty at the time of settlement. At settlement, if the NYMEX West Texas Intermediate crude oil index price (“WTI”) is below the floor price of the put, the Company receives the difference between the floor price and WTI multiplied by the contract volumes, less the premium. If WTI settles at or above the floor price of the put, the Company pays only the premium.

All derivative instruments are recorded on the Company’s Condensed Consolidated Balance Sheet as either assets or liabilities measured at fair value (see Note 5 – Fair Value Measurements). The Company has not designated any derivative instruments as hedges for accounting purposes and does not enter into such instruments for speculative trading purposes. If a derivative does not qualify as a hedge or is not designated as a hedge, the changes in fair value are recognized in the other income (expense) section of the Company’s Condensed Consolidated Statement of Operations as a net gain or loss on derivative instruments. The Company’s cash flow is only impacted when the actual settlements under the derivative contracts result in making a payment to or receiving a payment from the counterparty. These cash settlements represent the cumulative gains and losses on the Company’s derivative instruments and do not include a recovery of costs that were paid to acquire or modify the derivative instruments that were settled. Cash settlements are reflected as investing activities in the Company’s Condensed Consolidated Statement of Cash Flows.

In accordance with the FASB’s authoritative guidance on disclosures about offsetting assets and liabilities, the Company is required to disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position as well as instruments and transactions subject to an agreement similar to a master netting agreement. The Company’s derivative instruments are presented as assets and liabilities on a net basis by counterparty, as all counterparty contracts provide for net settlement. No margin or collateral balances are deposited with counterparties, and as such, gross amounts are offset to determine the net amounts presented in the Company’s Condensed Consolidated Balance Sheet.

7. Long-Term Debt

Senior unsecured notes. During 2013, the Company issued $1,000.0 million of 6.875% senior unsecured notes due March 15, 2022 (the “2022 Notes”), which resulted in aggregate net proceeds to the Company of $983.6 million . The Company used the proceeds from the 2022 Notes to fund the acquisition of oil and gas properties. During 2011 and 2012, the Company issued $400.0 million of 7.25% senior unsecured notes due February 1, 2019 (the “2019 Notes”), $400.0 million of 6.5% senior unsecured notes due November 1, 2021 (the “2021 Notes”) and $400.0 million of 6.875% senior unsecured notes due January 15, 2023 (the “2023 Notes”), which resulted in aggregate net proceeds to the Company of $1,175.8 million . The Company used the proceeds from these notes to fund its exploration, development and acquisition program and for general corporate purposes. Interest on the 2019 Notes, the 2021 Notes, the 2022 Notes and the 2023 Notes (collectively, the “Notes”) is payable semi-annually in arrears.

The Notes were issued under indentures containing provisions that are substantially the same, as amended and supplemented by supplemental indentures (collectively, the “Indentures”), among the Company, along with its material subsidiaries (the “Guarantors”), and U.S. Bank National Association, as trustee. The Notes are guaranteed on a senior unsecured basis by the Company’s Guarantors, which are 100% owned by the Company. These guarantees are full and unconditional and joint and several among the Guarantors, subject to certain customary release provisions, as follows:


•	in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary (as defined in the Indentures) of the Company;

•

in connection with any sale or other disposition of the capital stock of that Guarantor (including by way of merger or consolidation) to a person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, such that, immediately after giving effect to such transaction, such Guarantor would no longer constitute a subsidiary of the Company;


•	if the Company designates any Restricted Subsidiary that is a Guarantor to be an unrestricted subsidiary in accordance with the Indenture;


•	upon legal defeasance or satisfaction and discharge of the Indenture; or


•	upon the liquidation or dissolution of a Guarantor, provided no event of default occurs under the Indentures as a result thereof.

Prior to certain dates, the Company has certain options to redeem up to 35% of the Notes at a certain redemption price based on a percentage of the principal amount, plus accrued and unpaid interest to the redemption date, with the proceeds of certain equity offerings so long as the redemption occurs within 180 days of completing such equity offering and at least 65% of the aggregate principal amount of the Notes remains outstanding after such redemption. Prior to certain dates, the Company has the option to redeem some or all of the Notes for cash at certain redemption prices equal to a certain percentage of their principal amount plus an applicable make-whole premium and accrued and unpaid interest to the redemption date. The Company estimates that the fair value of these redemption options is immaterial at June 30, 2015 and December 31, 2014 .

The Indentures restrict the Company’s ability and the ability of certain of its subsidiaries to: (i) incur additional debt or enter into sale and leaseback transactions; (ii) pay distributions on, redeem or repurchase equity interests; (iii) make certain investments; (iv) incur liens; (v) enter into transactions with affiliates; (vi) merge or consolidate with another company; and (vii) transfer and sell assets. These covenants are subject to certain exceptions and qualifications. If at any time when the Notes are rated investment grade by both Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no Default (as defined in the Indentures) has occurred and is continuing, many of such covenants will terminate and the Company and its subsidiaries will cease to be subject to such covenants.

The Indentures contain customary events of default, including:


•	default in any payment of interest on any Note when due, continued for 30 days;


•	default in the payment of principal or premium, if any, on any Note when due;


•	failure by the Company to comply with its other obligations under the Indentures, in certain cases subject to notice and grace periods;


•	payment defaults and accelerations with respect to other indebtedness of the Company and its Restricted Subsidiaries in the aggregate principal amount of $10.0 million or more;

Table of Contents


•	certain events of bankruptcy, insolvency or reorganization of the Company or a Significant Subsidiary (as defined in the Indentures) or group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary;


•	failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary to pay certain final judgments aggregating in excess of $10.0 million within 60 days; and


•	any guarantee of the Notes by a Guarantor ceases to be in full force and effect, is declared null and void in a judicial proceeding or is denied or disaffirmed by its maker.

Senior secured revolving line of credit. On April 5, 2013, the Company, as parent, and OPNA, as borrower, entered into a second amended and restated credit agreement (the “Second Amended Credit Facility”), which had a maturity date of April 5, 2018 . The Second Amended Credit Facility is restricted to the borrowing base, which is reserve-based and subject to semi-annual redeterminations on April 1 and October 1 of each year. On April 13, 2015, the Company entered into its third amendment to the Second Amended Credit Facility (the “Third Amendment”), which extended the maturity date of the Second Amended Credit Facility to April 13, 2020, provided that the 2019 Notes are retired or refinanced 90 days prior to their maturity. In connection with the Third Amendment, the lenders under the Second Amended Credit Facility (the “Lenders”) completed their regular semi-annual redetermination of the borrowing base scheduled for April 1, 2015, resulting in a borrowing base decrease from $2,000.0 million to $1,700.0 million . The Company increased the Lenders’ aggregate elected commitment from $1,500.0 million to $1,525.0 million . The Lenders’ aggregate commitment can be increased to the full $1,700.0 million borrowing base by increasing the commitment of one or more Lenders. The Third Amendment also increased the Lenders in the bank group to 18 financial institutions supporting the Company’s borrowing base facility. The overall senior secured line of credit under the Second Amended Credit Facility is $2,500.0 million as of June 30, 2015 .

Borrowings under the Second Amended Credit Facility are collateralized by perfected first priority liens and security interests on substantially all of the Company’s assets, including mortgage liens on oil and natural gas properties having at least 80% of the reserve value as determined by reserve reports.

Borrowings under the Second Amended Credit Facility are subject to varying rates of interest based on (1) the total outstanding borrowings (including the value of all outstanding letters of credit) in relation to the borrowing base and (2) whether the loan is a London interbank offered rate (“LIBOR”) loan or a domestic bank prime interest rate loan (defined in the Second Amended Credit Facility as an Alternate Based Rate or “ABR” loan). As of June 30, 2015 , any outstanding LIBOR and ABR loans bore their respective interest rates plus the applicable margin indicated in the following table:



Ratio of Total Outstanding Borrowings to Borrowing Base	Applicable Margin for LIBOR Loans		Applicable Margin for ABR Loans
Less than .25 to 1	1.50	%	0.00	%
Greater than or equal to .25 to 1 but less than .50 to 1	1.75	%	0.25	%
Greater than or equal to .50 to 1 but less than .75 to 1	2.00	%	0.50	%
Greater than or equal to .75 to 1 but less than .90 to 1	2.25	%	0.75	%
Greater than or equal to .90 to 1	2.50	%	1.00	%

An ABR loan may be repaid at any time before the scheduled maturity of the Second Amended Credit Facility upon the Company providing advance notification to the Lenders. Interest is paid quarterly on ABR loans based on the number of days an ABR loan is outstanding as of the last business day in March, June, September and December. The Company has the option to convert an ABR loan to a LIBOR-based loan upon providing advance notification to the Lenders. The minimum available loan term is one month and the maximum loan term is six months for LIBOR-based loans. Interest for LIBOR loans is paid upon maturity of the loan term. Interim interest is paid every three months for LIBOR loans that have loan terms greater than three months in duration. At the end of a LIBOR loan term, the Second Amended Credit Facility allows the Company to elect to repay the borrowing, continue a LIBOR loan with the same or a differing loan term or convert the borrowing to an ABR loan.

On a quarterly basis, the Company pays a 0.375% (as of June 30, 2015 ) annualized commitment fee on the average amount of borrowing base capacity not utilized during the quarter and fees calculated on the average amount of letter of credit balances outstanding during the quarter.

As of June 30, 2015 , the Second Amended Credit Facility contained covenants that included, among others:


•	a prohibition against incurring debt, subject to permitted exceptions;


•	a prohibition against making dividends, distributions and redemptions, subject to permitted exceptions;

Table of Contents


•	a prohibition against making investments, loans and advances, subject to permitted exceptions;


•	restrictions on creating liens and leases on the assets of the Company and its subsidiaries, subject to permitted exceptions;


•	restrictions on merging and selling assets outside the ordinary course of business;


•	restrictions on use of proceeds, investments, transactions with affiliates or change of principal business;


•	a provision limiting oil and natural gas derivative financial instruments;


•	a requirement that the Company maintain a ratio of consolidated EBITDAX (as defined in the Second Amended Credit Facility) to consolidated Interest Expense (as defined in the Second Amended Credit Facility) of no less than 2.5 to 1.0 for the four quarters ended on the last day of each quarter; and

•

a requirement that the Company maintain a Current Ratio (as defined in the Second Amended Credit Facility) of consolidated current assets (including unused borrowing base capacity and with exclusions as described in the Second Amended Credit Facility) to consolidated current liabilities (with exclusions as described in the Second Amended Credit Facility) of no less than 1.0 to 1.0 as of the last day of any fiscal quarter.

The Second Amended Credit Facility contains customary events of default. If an event of default occurs and is continuing, the Lenders may declare all amounts outstanding under the Second Amended Credit Facility to be immediately due and payable.

As of June 30, 2015 , the Company had $155.0 million of LIBOR loans and $5.2 million of outstanding letters of credit issued under the Second Amended Credit Facility, resulting in an unused borrowing base committed capacity of $1,364.8 million . As of June 30, 2015 and December 31, 2014 , the weighted average interest rate on borrowings outstanding under the Second Amended Credit Facility was 1.7% and 1.9% , respectively. The Company was in compliance with the financial covenants of the Second Amended Credit Facility as of June 30, 2015 .

Deferred financing costs. As of June 30, 2015 , the Company had $35.1 million of deferred financing costs related to the Notes and the Second Amended Credit Facility. The deferred financing costs are included in deferred costs and other assets on the Company’s Condensed Consolidated Balance Sheet at June 30, 2015 and are being amortized over the respective terms of the Notes and the Second Amended Credit Facility. Amortization of deferred financing costs recorded for the three and six months ended June 30, 2015 was $2.4 million and $4.0 million , respectively, and $1.6 million and $3.2 million for the three and six months ended June 30, 2014 , respectively. These costs are included in interest expense on the Company’s Condensed Consolidated Statement of Operations.

(1)	Included in depreciation, depletion and amortization on the Company’s Condensed Consolidated Statement of Operations.

At June 30, 2015 , the current portion of the total ARO balance was approximately $0.7 million and is included in accrued liabilities on the Company’s Condensed Consolidated Balance Sheet.

9. Income Taxes

The Company’s effective tax rate for the three and six months ended June 30, 2015 was 36.7% and 34.9% , respectively, and 37.5% and 37.4% for the three and six months ended June 30, 2014 , respectively. While the 2014 rates were consistent with the statutory tax rate applicable to the U.S. and the blended state rate for the states in which the Company conducts business, the effective tax rate for the six months ended June 30, 2015 was lower due to permanent differences between the compensation amounts expensed for book purposes versus the amounts deductible for income tax purposes and the impact of a

Table of Contents

reduction in the North Dakota statutory tax rate in the second quarter of 2015. As of June 30, 2015 , the Company did not have any uncertain tax positions requiring adjustments to its tax liability.

The Company had deferred tax assets for its federal and state tax loss carryforwards at June 30, 2015 recorded in deferred income taxes. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of June 30, 2015 , management determined that a valuation allowance was not required for the tax loss carryforwards as they are expected to be fully utilized before expiration.

10. Stock-Based Compensation

Restricted stock awards. The Company has granted restricted stock awards to employees and directors under its Amended and Restated 2010 Long Term Incentive Plan, the majority of which vest over a three -year period. The fair value of restricted stock grants is based on the closing sales price of the Company’s common stock on the date of grant. Compensation expense is recognized ratably over the requisite service period. For the six months ended June 30, 2015 , the Company assumed annual forfeiture rates by employee group ranging from 0% to 16.9% based on the Company’s forfeiture history for this type of award.

During the six months ended June 30, 2015 , employees and non-employee directors of the Company were granted restricted stock awards equal to 1,223,420 shares of common stock with a $ 13.10 weighted average grant date per share value. Stock-based compensation expense recorded for restricted stock awards for the three and six months ended June 30, 2015 was $5.1 million and $11.8 million , respectively, and $4.3 million and $8.2 million for the three and six months ended June 30,

2014 , respectively. Stock-based compensation expense is included in general and administrative expenses on the Company’s Condensed Consolidated Statement of Operations.

Performance share units. The Company has granted performance share units (“PSUs”) to officers of the Company under its Amended and Restated 2010 Long Term Incentive Plan. The PSUs are awards of restricted stock units, and each PSU that is earned represents the right to receive one share of the Company’s common stock. For the six months ended June 30, 2015 , the Company assumed annual forfeiture rates by employee group ranging from 2.4% to 4.9% based on the Company’s forfeiture history for the officer employee groups receiving PSUs.

During the six months ended June 30, 2015 , officers of the Company were granted 425,590 PSUs with an $ 11.20 weighted average grant date per share value. Stock-based compensation expense recorded for PSUs for the three and six months ended June 30, 2015 was $1.0 million and $1.9 million , respectively, and $0.9 million and $1.5 million for the three and six months ended June 30, 2014 , respectively, and is included in general and administrative expenses on the Company’s Condensed Consolidated Statement of Operations.

Each grant of PSUs is subject to a designated three -year initial performance period. The number of PSUs to be earned is subject to a market condition, which is based on a comparison of the total shareholder return (“TSR”) achieved with respect to shares of the Company’s common stock against the TSR achieved by a defined peer group at the end of the performance period. Depending on the Company’s TSR performance relative to the defined peer group, award recipients will earn between 0% and 200% of the initial PSUs granted. If less than 200% of the initial PSUs granted are earned at the end of the initial three -year performance period, then the performance period will be extended an additional year to give the award recipients the opportunity to earn up to an aggregate of 200% of the initial PSUs granted.

The Company accounted for these PSUs as equity awards pursuant to the FASB’s authoritative guidance for share-based payments. The aggregate grant date fair value of the market-based awards was determined using a Monte Carlo simulation model, which results in an expected percentage of PSUs earned. The fair value of these PSUs is recognized on a straight-line basis over the performance period. As it is probable that a portion of the awards will be earned during the extended performance period, the grant date fair value will be amortized over four years . However, if 200% of the initial PSUs granted are earned at the end of the initial performance period, then the remaining compensation expense will be accelerated in order to be fully recognized over three years . All compensation expense related to the PSUs will be recognized if the requisite performance period is fulfilled, even if the market condition is not achieved.

The Monte Carlo simulation model uses assumptions regarding random projections and must be repeated numerous times to achieve a probabilistic assessment. The key valuation assumptions for the Monte Carlo model are the forecast period, initial value, risk-free interest rate, volatility and correlation coefficients. The risk-free interest rate is the U.S. Treasury bond rate on the date of grant that corresponds to the extended performance period. The initial value is the average of the volume weighted average prices for the 30 trading days prior to the start of the performance cycle for the Company and each of its peers. Volatility is the standard deviation of the average percentage change in stock price over a historical period for the Company and each of its peers. The correlation coefficients are measures of the strength of the linear relationship between and amongst the Company and its peers estimated based on historical stock price data.

The following assumptions were used for the Monte Carlo model to determine the grant date fair value and associated stock-based compensation expense of the PSUs granted during the six months ended June 30, 2015 :



Forecast period (years)	4.00
Risk-free interest rate	0.99	%
Oasis stock price volatility	50.11	%

For the PSUs granted during the six months ended June 30, 2015 , the Monte Carlo simulation model resulted in 86% of PSUs expected to be earned over the extended performance period.

11. Common Stock

On March 9, 2015, the Company completed a public offering of 36,800,000 shares of its common stock (including 4,800,000 shares issued pursuant to the underwriters’ option to purchase additional common stock) at an offering price of $12.80 per share. Net proceeds from the offering were $463.1 million , after deducting underwriting discounts and commissions and estimated offering expenses, of which $0.4 million is included in common stock and $462.7 million is included in additional paid-in capital on the Company’s Condensed Consolidated Balance Sheet. The Company used the net proceeds to repay outstanding indebtedness under its Second Amended Credit Facility and for general corporate purposes. The offering was made pursuant to an effective shelf registration statement on Form S-3 filed with the SEC on July 15, 2014.

12. Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the periods presented. The calculation of diluted earnings (loss) per share includes the impact of potentially dilutive non-vested restricted shares and PSUs outstanding during the periods presented, unless their effect is anti-dilutive. There are no adjustments made to income (loss) available to common stockholders in the calculation of diluted earnings (loss) per share.

The following is a calculation of the basic and diluted weighted-average shares outstanding for the three and six months ended June 30, 2015 and 2014 :



	Three Months Ended June 30,		Six Months Ended June 30,
	2015	2014	2015	2014
	(In thousands)
Basic weighted average common shares outstanding	136,859	99,663	123,157	99,612
Dilution effect of stock awards at end of period ⁽¹⁾	—	597	—	716
Diluted weighted average common shares outstanding	136,859	100,260	123,157	100,328
Anti-dilutive stock-based compensation awards	2,993	1,115	3,012	909

___________________


(1)	No unvested stock awards were included in computing loss per share for the three and six months ended June 30, 2015 because the effect was anti-dilutive.

13. Business Segment Information

The Company’s exploration and production segment is engaged in the acquisition and development of oil and natural gas properties and includes the complementary marketing services provided by OPM. Revenues for the exploration and production segment are derived from the sale of oil and natural gas production. In the first quarter of 2012, the Company began its well services business segment (OWS) to perform completion services for the Company’s oil and natural gas wells operated by OPNA. Revenues for the well services segment are derived from providing well completion services, well completion product sales and tool rentals. In the first quarter of 2013, the Company formed its midstream services business segment (OMS) to perform salt water disposal and other midstream services for the Company’s oil and natural gas wells operated by OPNA. Revenues for the midstream segment are primarily derived from salt water transport, salt water disposal and fresh water sales. The revenues and expenses related to work performed by OWS and OMS for OPNA’s working interests are eliminated in consolidation, and only the revenues and expenses related to non-affiliated working interest owners are included in the Company’s Condensed Consolidated Statement of Operations. These segments represent the Company’s three current operating units, each offering different products and services. The Company’s corporate activities have been allocated to the supported business segments accordingly.

Management evaluates the performance of the Company’s business segments based on operating income, which is defined as segment operating revenues less operating expenses, including depreciation, depletion and amortization. The following table summarizes financial information for the Company’s business segments for the periods presented:

14. Commitments and Contingencies

Included below is a discussion of various future commitments of the Company as of June 30, 2015 . The commitments under these arrangements are not recorded in the accompanying Condensed Consolidated Balance Sheet.

Lease obligations. The Company’s total rental commitments under leases for office space and other property and equipment at June 30, 2015 were $30.7 million .

Table of Contents

Drilling contracts. As a result of its lowered 2015 capital expenditure program, the Company elected to early terminate certain drilling rig contracts and recorded rig termination expense of $2.8 million and $3.9 million in its Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2015 , respectively. The Company did not elect to early terminate any drilling rig contracts during the six months ended June 30, 2014 .

As of June 30, 2015 , the Company had certain drilling rig contracts with initial terms greater than one year. In the event of early termination under these contracts, the Company would be obligated to pay approximately $8.5 million as of June 30, 2015 for the days remaining through the end of the primary terms of the contracts.

Volume commitment agreements. As of June 30, 2015 , the Company had certain agreements with an aggregate requirement to deliver a minimum quantity of approximately 30.2 MMBbl and 5.3 Bcf, prior to any applicable volume credits, from its Williston Basin project area within specified timeframes, all of which are less than ten years . Future commitments under these agreements were approximately $185.6 million as of June 30, 2015 .

Purchase agreements . As of June 30, 2015 , the Company had certain agreements for the purchase of fresh water with an aggregate future commitment of approximately $38.9 million .

Cost sharing agreements. As of June 30, 2015 , the Company had certain agreements to share the cost to construct and install electrical facilities. The Company’s estimated future commitment under these agreements was $4.5 million as of June 30, 2015 .

Litigation. The Company is party to various legal and/or regulatory proceedings from time to time arising in the ordinary course of business. While the ultimate outcome and impact to the Company cannot be predicted with certainty, the Company believes that all such matters are without merit and involve amounts which, if resolved unfavorably, either individually or in the aggregate, will not have a material adverse effect on its financial condition, results of operations or cash flows. When the Company determines that a loss is probable of occurring and is reasonably estimable, the Company accrues an undiscounted liability for such contingencies based on its best estimate using information available at the time. The Company discloses contingencies where an adverse outcome may be material, or in the judgment of management, the matter should otherwise be disclosed.

On July 6, 2013, a freight train operated by Montreal, Maine and Atlantic Railway (“MMA”) carrying crude oil (the “Train”) derailed in Lac-Mégantic, Quebec. In March 2014, Oasis Petroleum Inc. and OP LLC were added to a group of over fifty named defendants, including other crude oil producers as well as the Canadian Pacific Railway, MMA and certain of its affiliates, owners and transloaders of the crude oil carried by the Train, several lessors of tank cars, and the Attorney General of Canada, in a motion filed in Quebec Superior Court to authorize a class-action lawsuit seeking economic, compensatory and punitive damages, as well as costs for claims arising out of the derailment of the Train ( Yannick Gagne, etc., et al. v. Rail World, Inc., etc., et al. , Case No. 48006000001132) (the “Class-Action”). The motion generally alleges wrongful death and negligence in the failure to provide for the proper and safe transportation of crude oil. The Company believes that all claims against Oasis Petroleum Inc. and OP LLC in connection with the derailment of the Train in Lac-Mégantic, Quebec are without merit.

On August 7, 2013, MMA filed for bankruptcy protection in the Quebec Superior Court and the United States Bankruptcy Court in Bangor, Maine (together, the “Bankruptcy Actions”). The trustees appointed in the Bankruptcy Actions have negotiated settlement agreements with the majority of the named defendants in the Class-Action, including Oasis Petroleum Inc. and OP LLC. The Quebec Superior Court has approved the settlement agreement which was pending before it, but such approval is subject to appeal. The second settlement agreement remains pending before the United States Bankruptcy Court in Bangor, Maine. If approved, pursuant to the settlement agreements, Oasis Petroleum Inc. and OP LLC have agreed to contribute to the compensation fund established for those suffering losses as a result of the Lac-Megantic derailment. The Company has determined that such contributions are fully covered by the Company’s insurance policies. Furthermore, the settlement agreements would bar future litigation against Oasis Petroleum Inc. and OP LLC in Canada and the United States arising out of the Lac-Megantic derailment.

15. Condensed Consolidating Financial Information

The Notes (see Note 7) are guaranteed on a senior unsecured basis by the Guarantors, which are 100% owned by the Company. These guarantees are full and unconditional and joint and several among the Guarantors. Certain of the Company’s immaterial wholly-owned subsidiaries do not guarantee the Notes (“Non-Guarantor Subsidiaries”).

The following financial information reflects consolidating financial information of the parent company, Oasis Petroleum Inc. (“Issuer”), and its Guarantors on a combined basis, prepared on the equity basis of accounting. The Non-Guarantor Subsidiaries are immaterial and, therefore, not presented separately. The information is presented in accordance with the requirements of Rule 3-10 under the SEC’s Regulation S-X. The financial information may not necessarily be indicative of results of operations, cash flows or financial position had the Guarantors operated as independent entities. The Company has not presented separate financial and narrative information for each of the Guarantors because it believes such financial and narrative information would not provide any additional information that would be material in evaluating the sufficiency of the Guarantors.

Overview

We are an independent exploration and production (“E&P”) company focused on the acquisition and development of unconventional oil and natural gas resources primarily in the North Dakota and Montana regions of the Williston Basin. Since our inception, we have acquired properties that provide current production and significant upside potential through further development. Our drilling activity is primarily directed toward projects that we believe can provide us with repeatable successes in the Bakken and Three Forks formations. Oasis Petroleum North America LLC (“OPNA”) conducts our domestic oil and natural gas E&P activities. We also operate an oil and gas marketing business, Oasis Petroleum Marketing LLC (“OPM”), a well services business, Oasis Well Services LLC (“OWS”), and a midstream services business, Oasis Midstream Services LLC (“OMS”), which are all complementary to our primary development and production activities. OWS and OMS are separate reportable business segments, while OPM is included in our E&P segment. The revenues and expenses related to work performed by OPM, OWS and OMS for OPNA’s working interests are eliminated in consolidation and, therefore, do not directly contribute to our consolidated results of operations.

Our use of capital for acquisitions and development allows us to direct our capital resources to what we believe to be the most attractive opportunities as market conditions evolve. We have historically acquired properties that we believe will meet or exceed our rate of return criteria. We built our Williston Basin assets through acquisitions and development activities, which were financed with a combination of capital from private investors, borrowings under our revolving credit facility, cash flows provided by operating activities, proceeds from our senior unsecured notes, proceeds from our public equity offerings and the sale of non-core oil and gas properties. For acquisitions of properties with additional development, exploitation and exploration potential, we have focused on acquiring properties that we expect to operate so that we can control the timing and implementation of capital spending. In some instances, we have acquired non-operated property interests at what we believe to be attractive rates of return either because they provided an entry into a new area of interest or complemented our existing operations. We intend to continue to acquire both operated and non-operated properties to the extent we believe they meet our return objectives. In addition, the acquisition of non-operated properties in new areas provides us with geophysical and geologic data that may lead to further acquisitions in the same area, whether on an operated or non-operated basis.

Due to the geographic concentration of our oil and natural gas properties in the Williston Basin, we believe the primary sources of opportunities, challenges and risks related to our business for both the short and long-term are:


•	commodity prices for oil and natural gas;


•	transportation capacity;


•	availability and cost of services; and


•	availability of qualified personnel.

Our revenue, profitability and future growth rate depend substantially on factors beyond our control, such as economic, political and regulatory developments as well as competition from other sources of energy. Oil and natural gas prices historically have been volatile and may fluctuate widely in the future. Crude oil prices declined significantly in the latter part of 2014 and have remained low in 2015. As a result of lower oil prices, we have significantly decreased our planned 2015 capital expenditures as compared to 2014, and we are currently concentrating our drilling activities in certain areas that are the most economic in the Williston Basin. Sustained periods of low prices for oil or natural gas could materially and adversely affect our financial position, our results of operations, the quantities of oil and natural gas reserves that we can economically produce and our access to capital.

Prices for oil and natural gas can fluctuate widely in response to relatively minor changes in the global and regional supply of and demand for oil and natural gas, as well as market uncertainty, economic conditions and a variety of additional factors. Since the inception of our oil and natural gas activities, commodity prices have experienced significant fluctuations, including the recent substantial decline in oil prices since June 2014 caused by the current oversupply of crude oil. We enter into crude oil sales contracts with purchasers who have access to crude oil transportation capacity, utilize derivative financial instruments to manage our commodity price risk and enter into physical delivery contracts to manage our price differentials. In an effort to improve price realizations from the sale of our oil and natural gas, we manage our commodities marketing activities in-house, which enables us to market and sell our oil and natural gas to a broader array of potential purchasers. Due to the

Table of Contents

availability of other markets and pipeline connections, we do not believe that the loss of any single oil or natural gas customer would have a material adverse effect on our results of operations or cash flows. Additionally, we sell a significant amount of our crude oil production through gathering systems connected to multiple pipeline and rail facilities. These gathering systems, which originate at the wellhead, reduce the need to transport barrels by truck from the wellhead. As of June 30, 2015 , we were flowing 79% of our gross operated oil production through these gathering systems.

Changes in commodity prices may also significantly affect the economic viability of drilling projects and economic recovery of oil and gas reserves. Higher oil prices in 2010 to 2014, as well as continued successes in the application of completion technologies in the Bakken and Three Forks formations, caused the active drilling rig count in the Williston Basin to increase to over 200 rigs during 2014. However, the active rig count has decreased to less than 70 in July 2015 due to the substantial decline in oil prices. Although Williston Basin transportation takeaway capacity, including expanded rail and pipeline infrastructure, was added from 2011 to 2014, production also increased due to the elevated drilling activity during these years, resulting in price differentials in a historical average range of approximately 10% to 15% of the NYMEX West Texas Intermediate crude oil index prices (“WTI”). At the beginning of 2014, our average price differentials to WTI were elevated due to the pipeline market weakening as a result of refinery down time and increased United States and Canadian production. In the second and third quarters of 2014, stronger pipeline prices shifted more of our barrels towards the pipelines, but rail buyers had to compete with pipeline prices despite weaker Brent differentials. As a result, our price differentials to WTI returned to approximately 9% to 11%. In the fourth quarter of 2014, as WTI declined, our price differentials increased as a percentage of WTI but remained relatively flat in terms of the dollar per barrel discount to WTI in the range of $9.00 to $10.50 per barrel of oil. In the first quarter of 2015, as WTI further declined, our price differentials continued to increase as a percentage of WTI but decreased in terms of the dollar per barrel discount to WTI to an average of $7.85 per barrel of oil. In the second quarter of 2015, as WTI improved, our price differentials returned to approximately 10% as a percentage of WTI and continued to decrease in terms of the dollar per barrel discount to WTI to an average of $5.90 per barrel of oil. We expect our price differential to WTI to range between $5.50 and $6.50 per Boe in the third quarter of 2015. Our market optionality on the crude oil gathering systems allows us to shift volumes between pipeline and rail markets in order to optimize price realizations.

Second Quarter 2015 Highlights:


•	We completed and placed on production 21 gross ( 18.5 net) operated wells in the Williston Basin during the three months ended June 30, 2015 ;


•	Average daily production was 50,261 Boe per day during the three months ended June 30, 2015 ;


•	We decreased lease operating expenses to $8.26 per Boe for the three months ended June 30, 2015 ;


•	For the three months ended June 30, 2015 , total capital expenditures were $170.4 million, in line with our plan;


•	At June 30, 2015 , we had $13.7 million of cash and cash equivalents and had total liquidity of $1,378.5 million , including the availability under our revolving credit facility; and


•	Adjusted EBITDA, a non-GAAP financial measure, was $245.4 million for the three months ended June 30, 2015 . For a definition of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income and net cash provided by operating activities, see “Non-GAAP Financial Measures” below.

Results of Operations

Revenues

Our oil and gas revenues are derived from the sale of oil and natural gas production. These revenues do not include the effects of derivative instruments and may vary significantly from period to period as a result of changes in volumes of production sold or changes in commodity prices. Our well services and midstream revenues are primarily derived from well completion activity, well completion product sales, tool rentals, salt water transport, salt water disposal and fresh water sales for third-party working interest owners in OPNA’s operated wells. Intercompany revenues for work performed by OWS and OMS for OPNA’s working interests are eliminated in consolidation.

Three months ended June 30, 2015 as compared to three months ended June 30, 2014

Our total revenues decreased $142.3 million , or 38% , to $230.0 million during the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 , primarily due to lower realized oil and natural gas sales prices, partially offset by increased production volumes sold. Our average realized prices for oil and natural gas decreased by 45% and 78%, respectively, during the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 .

Oil and gas revenues . Our primary revenues are a function of oil and natural gas production volumes sold and average sales prices received for those volumes. Average daily production sold increased by 6,593 Boe per day, or 15% , to 50,261 Boe per day during the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 . The increase in average daily production sold was primarily a result of our 128.1 total net well completions in the Williston Basin during the twelve months ended June 30, 2015 , offset by the decline in production in wells that were producing as of June 30, 2014 . Average oil sales prices, without derivative settlements, decreased by $42.44 /Bbl to an average of $52.04 /Bbl, and average natural gas sales prices, which include the value for natural gas and natural gas liquids, decreased by $5.93 /Mcf to an average of $1.63 /Mcf for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 . The lower oil and natural gas sales prices decreased revenues by $165.7 million, partially offset by higher production amounts sold, which increased revenues by $25.6 million during the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 .

Well services and midstream revenues. Well services revenues decreased $5.7 million to $9.2 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 primarily due to a $7.4 million decrease in well completion product sales to third parties as a result of OWS completing substantially all of OPNA’s operated wells, partially offset by an increase in well completion activity. Midstream revenues were $6.7 million for the three months ended June 30, 2015 , which was a $3.4 million increase quarter over quarter, primarily due to increased water volumes flowing through our salt water disposal systems and increased fresh water sales.

Six months ended June 30, 2015 as compared to six months ended June 30, 2014

Our total revenues decreased $311.5 million , or 43% , to $410.4 million during the six months ended June 30, 2015 as compared to the three months ended June 30, 2014 , primarily due to lower realized oil and natural gas sales prices, partially

offset by increased production volumes sold. Our average realized prices for oil and natural gas decreased by 50% and 71%, respectively, during the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 .

Oil and gas revenues . Our primary revenues are a function of oil and natural gas production volumes sold and average sales prices received for those volumes. Average daily production sold increased by 7,089 Boe per day, or 16% , to 50,353 Boe per day during the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 . The increase in average daily production sold was primarily a result of our 128.1 total net well completions in the Williston Basin during the twelve months ended June 30, 2015 , offset by the decline in production in wells that were producing as of June 30, 2014 . Average oil sales prices, without derivatives settlements, decreased by $45.73 /Bbl to an average of $46.37 /Bbl, and average natural gas sales prices, which include the value for natural gas and natural gas liquids, decreased by $5.97 /Mcf to an average of $2.40 /Mcf for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 . The lower oil and natural gas sales prices decreased revenues by $349.8 million, partially offset by higher production amounts sold, which increased revenues by $51.7 million during the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 .

Well services and midstream revenues . Well services revenues decreased $18.8 million to $11.9 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 primarily due to a $10.0 million decrease in well completion product sales to third parties as a result of OWS completing substantially all of OPNA’s operated wells. In addition, well completion revenue decreased $8.2 million as a result of OWS completing OPNA wells with a lower average third-party working interest in the first half of 2015 as compared to the first half of 2014. While a lower average third-party working interest decreases the well completion revenue recognized in our consolidated results of operations, it improves our capital expenditures by reducing OPNA well costs. Midstream revenues were $10.5 million for the six months ended June 30, 2015 , which was a $5.4 million increase period over period, primarily due to increased water volumes flowing through our salt water disposal systems and increased fresh water sales.

Three months ended June 30, 2015 as compared to three months ended June 30, 2014

Lease operating expenses . Lease operating expenses decreased $2.8 million to $37.8 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 . This decrease was primarily due to lower workover costs and an increase in salt water disposal volumes being transported on OMS pipelines and injected in OMS salt water disposal wells, partially offset by higher costs associated with operating an increased number of producing wells. Lease operating expenses decreased from $10.21 per Boe for the three months ended June 30, 2014 to $8.26 per Boe for the three months ended June 30, 2015 due to the increase in oil and natural gas production and lower costs.

Well services and midstream operating expenses . Well services and midstream operating expenses represent third-party working interest owners’ share of completion service costs and cost of goods sold incurred by OWS and OMS. The $1.4 million decrease for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 was attributable to a $1.9 million decrease in well completion costs as a result of lower well completion product sales to third parties due to OWS completing substantially all of OPNA’s operated wells, partially offset by an increase in well completion activity. This net decrease was partially offset by a $0.5 million increase in operating expenses related to midstream services.

Table of Contents

Marketing, transportation and gathering expenses . The $0.5 million increase for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 was primarily attributable to an increase in gas gathering charges related to additional well connections on OMS infrastructure.

Production taxes . Our production taxes as a percentage of oil and natural gas sales were 9.6% and 9.7% , respectively, for the three months ended June 30, 2015 and 2014 . The production tax rate remained stable for the three months ended June 30, 2015 and 2014 primarily due to our production weighting remaining consistent between North Dakota and Montana in the comparative periods. For the three months ended June 30, 2015 and 2014 , the percentage of our total production located in North Dakota was 87% and 86%, respectively, with an average production tax rate of approximately 10%, as compared to a 6% average production tax rate on our production in Montana.

Depreciation, depletion and amortization (“DD&A”). DD&A expense increased $21.9 million to $119.2 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 . This increase in DD&A expense for the three months ended June 30, 2015 was a result of production increases from our wells completed during the twelve months ended June 30, 2015 . The DD&A rate for the three months ended June 30, 2015 was $26.07 per Boe compared to $24.48 per Boe for the three months ended June 30, 2014 . The increase in the DD&A rate was primarily due to increased exploratory and delineation drilling in the Three Forks formation, which produced lower recoverable reserves in comparison to the Bakken formation.

Impairment of oil and gas properties . During the three months ended June 30, 2015 and 2014 , we recorded non-cash impairment charges of $19.5 million and $42,000 , respectively, for unproved properties due to leases that expired during the period and periodic assessments of unproved properties not held-by-production. The impairment charge for the three months ended June 30, 2015 included $19.1 million related to acreage expiring within the next 12 months as a result of a periodic assessment because there were no current plans to drill or extend the leases prior to their expiration. For the three months ended June 30, 2014 , we did not record any impairment charges as a result of periodic assessments based on our ability to actively manage and prioritize our capital expenditures to drill leases and to make payments to extend leases that would otherwise expire. No impairment charges of proved oil and gas properties were recorded for the three months ended June 30, 2015 or 2014 .

General and administrative (“G&A”) expenses . Our G&A expenses increased $0.8 million to $21.5 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 . OWS and OMS G&A increased $0.8 million and $0.4 million, respectively, while G&A for our E&P segment decreased by $0.4 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014. The increase in OWS and OMS G&A was primarily due to increased employee compensation expense due to organizational growth within these segments in the second quarter of 2015 as compared to the second quarter of 2014. As of June 30, 2015 , we had 567 total full-time employees compared to 522 total full-time employees as of June 30, 2014 .

Gain on sale of properties. During the three months ended June 30, 2014 , we recognized a gain on sale of properties of $3.6 million for post close adjustments related to the sale of certain non-operated properties in and around our Sanish position (the “Sanish Divestiture”) in the first quarter of 2014.

Derivative instruments . As a result of entering into derivative contracts and the effect of the forward strip oil price changes, we incurred a $39.4 million net loss on derivative instruments, including net cash settlement receipts of $104.1 million , for the three months ended June 30, 2015 , and a $65.6 million net loss on derivative instruments, including net cash settlement payments of $11.4 million for the three months ended June 30, 2014 . Cash settlements represent the cumulative gains and losses on our derivative instruments for the periods presented and do not include recovery of costs that were paid to acquire or modify the derivative instruments that were settled.

Interest expense . Interest expense decreased $1.6 million to $37.4 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014 . The decrease was primarily the result of increased interest costs capitalized, partially offset by an increase in interest expense incurred on borrowings under our revolving credit facility. Interest capitalized during the three months ended June 30, 2015 and 2014 was $4.9 million and $2.3 million, respectively. The increase in interest capitalized was due to increased accumulated capital expenditures for assets not yet placed into production in the second quarter of 2015 as compared to the second quarter of 2014. For the three months ended June 30, 2015 and 2014 , the weighted average debt outstanding under our revolving credit facility was $184.7 million and $121.5 million, respectively. The weighted average interest rate incurred on the outstanding borrowings was 1.7% for each of the three months ended June 30, 2015 and 2014 .

Income taxes. Income tax expense for the three months ended June 30, 2015 and 2014 was recorded at 36.7% and 37.5% of pre-tax net income, respectively. Our effective tax rates for the three months ended June 30, 2015 and 2014 continue to approximate the statutory tax rate applicable to the U.S. and the blended state rate of the states in which we conduct business.

Six months ended June 30, 2015 as compared to six months ended June 30, 2014

Lease operating expense. Lease operating expenses decreased $3.7 million to $76.9 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 . The decrease was primarily due to lower workover costs and an increase in salt water disposal volumes being transported on OMS pipelines and injected in OMS salt water disposal wells, partially offset by higher costs associated with operating an increased number of producing wells. Lease operating expenses decreased from $10.29 per Boe for the six months ended June 30, 2014 to $8.44 per Boe for the six months ended June 30, 2015 due to the increase in oil and natural gas production and lower costs.

Well services and midstream operating expenses. Well services and midstream operating expenses represent third-party working interest owners’ share of completion service costs and cost of goods sold incurred by OWS and OMS. The $10.3 million decrease for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 was attributable to a $11.2 million decrease in well completion costs as a result of OWS completing OPNA wells with a lower average third-party working interest in the first half of 2015 as compared to the first half of 2014 and lower well completion product sales to third parties due to OWS completing substantially all of OPNA’s operated wells. This decrease was partially offset by a $0.9 million increase in operating expenses related to midstream services.

Marketing, transportation and gathering expenses. The $2.5 million increase for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 was primarily attributable to a $1.2 million increase in oil transportation costs associated with having additional wells connected to third-party infrastructure. The transporting of volumes through third-party oil gathering pipelines increases marketing transportation and gathering expenses but improves oil price realizations by reducing transportation costs included in our oil price differential for sales at the wellhead. In addition, there was an increase in gas gathering charges related to additional well connections on OMS infrastructure and a $0.5 million increase due to the change in non-cash valuation adjustments on our pipeline imbalances.

Production taxes. Our production taxes as a percentage of oil and natural gas sales were 9.6% and 9.7% , respectively for the six months ended June 30, 2015 and 2014 . The production tax rate remained stable for the six months ended June 30, 2015 and 2014 primarily due to our production weighting remaining consistent between North Dakota and Montana in the comparative periods. For the six months ended June 30, 2015 and 2014 , the percentage of our total production located in North Dakota was 87% and 86%, respectively, with an average production tax rate of approximately 10%, as compared to a 5% average production tax rate on our production in Montana.

Depreciation, depletion, and amortization. DD&A expense increased $49.1 million to $237.7 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 . The increase in DD&A expense for the six months ended June 30, 2015 was a result of production increases from our wells completed during the twelve months ended June 30, 2015 . The DD&A rate for the six months ended June 30, 2015 was $26.08 per Boe compared to $24.08 per Boe for the six months ended June 30, 2014 . The increase in the DD&A rate was primarily due to increased exploratory and delineation drilling in the Three Forks formation, which produced lower recoverable reserves in comparison to the Bakken formation.

Impairment of oil and gas properties. During the six months ended June 30, 2015 and 2014 , we recorded non-cash impairment charges of $24.8 million and $0.8 million , respectively, for unproved properties due to leases that expired during the period and periodic assessments of unproved properties not held-by-production. The impairment charge for the six months ended June 30, 2015 included $20.3 million related to acreage expiring in 2015 and the first half of 2016 as a result of a periodic assessment because there were no current plans to drill or extend the leases prior to their expiration. For the six months ended June 30, 2014 , we did not record any impairment charges as a result of periodic assessments based on our ability to actively manage and prioritize our capital expenditures to drill leases and to make payments to extend leases that would otherwise expire. No impairment charges of proved oil and gas properties were recorded for the six months ended June 30, 2015 or 2014 .

General and administrative expenses. Our G&A expenses increased $0.6 million for the six months ended June 30, 2015 from $44.3 million for the six months ended June 30, 2014 . E&P and OMS G&A increased by $1.5 million and $0.7 million, respectively, while G&A for our OWS segment decreased $1.6 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 . The increase in E&P and OMS G&A was primarily due to increased employee compensation expense due to our organizational growth and increased amortization of our restricted stock awards and performance share units period over period. The decrease in OWS G&A was primarily due to OWS completing OPNA wells with a lower average third-party working interest in the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 . As of June 30, 2015 , we had 567 total full-time employees compared to 522 total full-time employees as of June 30, 2014 .

Gain on sale of properties. During the six months ended June 30, 2014 , we recognized a gain on sale of properties of $187.0 million for the Sanish Divestiture.

Derivative instruments. As a result of entering into derivative contracts and the effect of the forward strip oil price changes, we incurred a $7.6 million net gain on derivative instruments, including net cash settlement receipts of $213.3 million , for the six months ended June 30, 2015 , and an $83.2 million net loss on derivative instruments, including net cash settlement payments of $13.6 million for the six months ended June 30, 2014 . Cash settlements represent the cumulative gains and losses on our derivative instruments for the periods presented and do not include recovery of costs that were paid to acquire or modify the derivative instruments that were settled.

Interest expense. Interest expense decreased $3.0 million to $76.2 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 . The decrease was primarily the result of increased interest costs capitalized, partially offset by an increase in the interest expense incurred on borrowings under our revolving credit facility. Interest capitalized during the six months ended June 30, 2015 and 2014 was $8.8 million and $3.8 million, respectively. The increase in interest capitalized was due to increased accumulated capital expenditures for assets not yet placed into production in the first half of 2015 as compared to the first half of 2014. For the six months ended June 30, 2015 and 2014 , the weighted average debt outstanding under our revolving credit facility was $639.0 million and $188.4 million, respectively, and the weighted average interest rate incurred on the outstanding borrowings was 1.8% and 1.7%, respectively.

Income taxes. Income tax expense for the six months ended June 30, 2015 and 2014 was recorded at 34.9% and 37.4% of pre-tax net income, respectively. While our 2014 rate was consistent with the statutory tax rate applicable to the U.S. and the blended state rate for the states in which we conduct business, our effective tax rate for the six months ended June 30, 2015 was lower due to permanent differences between the compensation amounts expensed for book purposes versus the amounts deductible for income tax purposes and the impact of a reduction in the North Dakota statutory tax rate in the second quarter of 2015.

Liquidity and Capital Resources

Our primary sources of liquidity as of the date of this report have been proceeds from our senior unsecured notes, borrowings under our revolving credit facility, proceeds from public equity offerings, cash flows from operations, the sale of non-core oil and gas properties and cash settlements of derivative contracts. Our primary uses of capital have been for the acquisition and development of oil and natural gas properties. We continually monitor potential capital sources, including equity and debt financings and potential asset monetizations, in order to enhance liquidity and decrease leverage. Our future success in growing proved reserves and production will be highly dependent on our ability to access outside sources of capital.

Our cash flows for the six months ended June 30, 2015 and 2014 are presented below:



	Six Months Ended June 30,
	2015			2014
	(In thousands)
Net cash provided by operating activities	$	229,886		$	486,254
Net cash used in investing activities	(374,500		)	(312,052		)
Net cash provided by (used in) financing activities	112,487			(239,146		)
Decrease in cash and cash equivalents	$	(32,127	)	$	(64,944	)

Our cash flows depend on many factors, including the price of oil and natural gas and the success of our development and exploration activities as well as future acquisitions. We actively manage our exposure to commodity price fluctuations by executing derivative transactions to mitigate the change in oil prices on a portion of our production, thereby mitigating our exposure to oil price declines, but these transactions may also limit our cash flow in periods of rising oil prices. Prices for oil declined significantly in the fourth quarter of 2014 and into 2015, which has substantially decreased our cash flows provided by operating activities. The decline in operating cash flows caused by lower oil prices is partially offset by cash flows from our derivative contracts. On March 9, 2015, we completed a public equity offering resulting in net proceeds of $463.1 million , after deducting underwriting discounts and commissions and estimated offering expenses, which we used to repay outstanding indebtedness under our revolving credit facility and for general corporate purposes. Our existing revolving credit facility provides additional liquidity, and after the borrowing base redetermination on April 13, 2015, our aggregate elected commitment amount increased from $1,500.0 million to $1,525.0 million. We believe we have adequate liquidity to fund our planned 2015 capital expenditures and to meet our future obligations. For additional information on the impact of changing prices on our financial position, see Item 3. “Quantitative and Qualitative Disclosures about Market Risk” below.

Cash flows provided by operating activities

Net cash provided by operating activities was $229.9 million and $486.3 million for the six months ended June 30, 2015 and 2014 , respectively. The decrease in cash flows provided by operating activities for the period ended June 30, 2015 as

Table of Contents

compared to 2014 was primarily the result of lower realized oil and natural gas sales prices coupled with decreases in well completion product sales to third parties and well completion revenue, offset by our 16% increase in oil and natural gas production and increases in salt water transport, salt water disposal and fresh water sales.

Working capital. Our working capital fluctuates primarily as a result of changes in commodity pricing and production volumes, capital spending to fund our exploratory and development initiatives and acquisitions, and the impact of our outstanding derivative instruments. We had a working capital deficit of $167.6 million at June 30, 2015 . We believe we have adequate liquidity to meet our working capital requirements. As of June 30, 2015 , we had $1,378.5 million of liquidity available, including $13.7 million in cash and cash equivalents and $1,364.8 million of unused borrowing base committed capacity available under our revolving credit facility. At June 30, 2014 , we had a working capital deficit of $217.5 million.

Cash flows used in investing activities

Net cash used in investing activities was $374.5 million and $312.1 million during the six months ended June 30, 2015 and 2014 , respectively. Net cash used in investing activities during the six months ended June 30, 2015 was primarily attributable to $586.7 million in capital expenditures primarily for drilling and development costs, partially offset by $213.3 million of derivative settlements received as a result of lower crude oil pricing. Net cash used in investing activities during the six months ended June 30, 2014 was primarily attributable to $606.9 million in capital expenditures primarily for drilling and development costs, partially offset by proceeds of $324.9 million related to the Sanish Divestiture.

Our capital expenditures are summarized in the following table:



	Six Months Ended June 30, 2015
	(In thousands)
Capital expenditures by business segment:
E&P	$	331,711
OMS	75,147
OWS	21,686
Other capital expenditures ⁽¹⁾	12,969
Total capital expenditures ⁽²⁾	$	441,513

___________________


(1)	Other capital expenditures include such items as administrative capital and capitalized interest.


(2)	Capital expenditures reflected in the table above differ from the amounts shown in the statement of cash flows in our condensed consolidated financial statements because amounts reflected in the table above include changes in accrued liabilities from the previous reporting period for capital expenditures, while the amounts presented in the statement of cash flows are presented on a cash basis.

Our total 2015 capital expenditure budget is $705 million, which includes $678 million for E&P capital expenditures and $27 million for non-E&P capital expenditures, including OWS, administrative capital and capitalized interest. Our planned E&P capital expenditures include $565 million of drilling and completion (including production-related equipment) capital expenditures for operated and non-operated wells (including expected savings from services provided by OWS and OMS).

While we have budgeted $705 million for these purposes, the ultimate amount of capital we will expend may fluctuate materially based on market conditions and the success of our drilling and operations results as the year progresses. Additionally, if we acquire additional acreage, our capital expenditures may be higher than budgeted. With our current pace of completions coupled with our lower well costs as of June 30, 2015, we are currently planning to invest approximately $670 million in total capital expenditures during 2015, as compared to our approved budget of $705 million. We believe that cash on hand, cash flows from operating activities, proceeds from cash settlements under our derivative contracts and availability under our revolving credit facility should be sufficient to fund our 2015 capital expenditure budget. However, because the operated wells funded by our 2015 drilling plan represent only a small percentage of our gross potential drilling locations, we will be required to generate or raise multiples of this amount of capital to develop our entire inventory of potential drilling locations should we elect to do so.

Our capital budget may be adjusted as business conditions warrant. The amount, timing and allocation of capital expenditures is largely discretionary and within our control. If oil prices remain low for an extended period of time or continue to decline, we could defer a significant portion of our budgeted capital expenditures until later periods to prioritize capital projects that we believe have the highest expected returns and potential to generate near-term cash flows. We routinely monitor and adjust our capital expenditures in response to changes in prices, availability of financing, drilling and acquisition costs, industry conditions, the timing of regulatory approvals, the availability of rigs, success or lack of success in drilling activities,

contractual obligations, internally generated cash flows and other factors both within and outside our control. We actively review acquisition opportunities on an ongoing basis. Our ability to make significant acquisitions for cash would require us to obtain additional equity or debt financing, which we may not be able to obtain on terms acceptable to us or at all.

Cash flows provided by and used in financing activities

Net cash provided by financing activities was $112.5 million for the six months ended June 30, 2015 , and net cash used in financing activities was $239.1 million for the six months ended June 30, 2014 . For the six months ended June 30, 2015 , cash provided by financing activities was primarily due to net proceeds from the issuance of our common stock and proceeds from borrowings under our revolving credit facility, partially offset by principal payments on our revolving credit facility. Net cash used in financing activities during the six months ended June 30, 2014 was primarily attributable to principal payments on our revolving credit facility, partially offset by proceeds from borrowings under our revolving credit facility. For both the six months ended June 30, 2015 and 2014 , cash was used in financing activities for the purchases of treasury stock for shares withheld by us equivalent to the payroll tax withholding obligations due from employees upon the vesting of restricted stock awards.

Sale of common stock. On March 9, 2015, we completed a public offering of 36,800,000 shares of our common stock at an offering price of $12.80 per share. We used the net proceeds from the offering of $463.1 million , after deducting underwriting discounts and commissions and estimated offering expenses, to repay outstanding indebtedness under our revolving credit facility and for general corporate purposes.

Senior unsecured notes. On September 24, 2013, we issued $1,000.0 million of 6.875% senior unsecured notes due March 15, 2022 (the “2022 Notes”). Interest is payable on the 2022 Notes semi-annually in arrears on each March 15 and September 15, commencing March 15, 2014. The issuance of these 2022 Notes resulted in net proceeds to us of $983.6 million, which we used to fund a portion of our 2013 acquisitions of oil and gas properties.

At any time prior to September 15, 2016, we may redeem up to 35% of the 2022 Notes at a redemption price of 106.875% of the principal amount, plus accrued and unpaid interest to the redemption date, with the proceeds of certain equity offerings as long as the redemption occurs within 180 days of completing such equity offering and at least 65% of the aggregate principal amount of the 2022 Notes remains outstanding after such redemption. Prior to September 15, 2017, we may redeem some or all of the 2022 Notes for cash at a redemption price equal to 100% of their principal amount plus an applicable make-whole premium and accrued and unpaid interest to the redemption date. On and after September 15, 2017, we may redeem some or all of the 2022 Notes at redemption prices (expressed as percentages of the principal amount) equal to 103.438% for the twelve-month period beginning on September 15, 2017, 101.719% for the twelve-month period beginning on September 15, 2018 and 100.00% beginning on September 15, 2019, plus accrued and unpaid interest to the redemption date.

On July 2, 2012, we issued $400.0 million of 6.875% senior unsecured notes due January 15, 2023 (the “2023 Notes”). Interest is payable on the 2023 Notes semi-annually in arrears on each January 15 and July 15, commencing January 15, 2013. The issuance of these 2023 Notes resulted in net proceeds to us of $392.4 million, which we used to fund our exploration, development and acquisition program and for general corporate purposes.

Prior to July 15, 2017, we may redeem some or all of the 2023 Notes for cash at a redemption price equal to 100% of their principal amount plus an applicable make-whole premium and accrued and unpaid interest to the redemption date. On and after July 15, 2017, we may redeem some or all of the 2023 Notes at redemption prices (expressed as percentages of the principal amount) equal to 103.438% for the twelve-month period beginning on July 15, 2017, 102.292% for the twelve-month period beginning on July 15, 2018, 101.146% for the twelve-month period beginning on July 15, 2019 and 100.00% beginning on July 15, 2020, plus accrued and unpaid interest to the redemption date.

On November 10, 2011, we issued $400.0 million of 6.5% senior unsecured notes due November 1, 2021 (the “2021 Notes”). Interest is payable on the 2021 Notes semi-annually in arrears on each May 1 and November 1, commencing May 1, 2012. The issuance of these 2021 Notes resulted in net proceeds to us of $393.4 million, which we used to fund our exploration, development and acquisition program and for general corporate purposes.

Prior to November 1, 2016, we may redeem some or all of the 2021 Notes for cash at a redemption price equal to 100% of their principal amount plus an applicable make-whole premium and accrued and unpaid interest to the redemption date. On and after November 1, 2016, we may redeem some or all of the 2021 Notes at redemption prices (expressed as percentages of the principal amount) equal to 103.25% for the twelve-month period beginning on November 1, 2016, 102.167% for the twelve-month period beginning on November 1, 2017, 101.083% for the twelve-month period beginning on November 1, 2018 and 100.00% beginning on November 1, 2019, plus accrued and unpaid interest to the redemption date.

On February 2, 2011, we issued $400.0 million of 7.25% senior unsecured notes due February 1, 2019 (the “2019 Notes”). Interest is payable on the 2019 Notes semi-annually in arrears on each February 1 and August 1, commencing August 1, 2011. The issuance of these 2019 Notes resulted in net proceeds to us of $390.0 million, which we used to fund our

exploration, development and acquisition program and for general corporate purposes. We may redeem some or all of the 2019 Notes at redemption prices (expressed as percentages of the principal amount) equal to 103.625% for the twelve-month period beginning on February 1, 2015, 101.813% for the twelve-month period beginning on February 1, 2016 and 100.00% beginning on February 1, 2017, plus accrued and unpaid interest to the redemption date.

The 2019 Notes, 2021 Notes, 2022 Notes and 2023 Notes (collectively, the “Notes”) are guaranteed on a senior unsecured basis by our material subsidiaries. The indentures governing the Notes restrict our ability and the ability of certain of our subsidiaries to: (i) incur additional debt or enter into sale and leaseback transactions; (ii) pay distributions on, redeem or repurchase equity interests; (iii) make certain investments; (iv) incur liens; (v) enter into transactions with affiliates; (vi) merge or consolidate with another company; and (vii) transfer and sell assets. These covenants are subject to a number of important exceptions and qualifications. If at any time when our Notes are rated investment grade by both Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no Default (as defined in the indentures) has occurred and is continuing, many of such covenants will terminate and we will cease to be subject to such covenants.

Senior secured revolving line of credit . On April 5, 2013, we entered into a second amended and restated credit agreement (the “Second Amended Credit Facility”), which had a maturity date of April 5, 2018. The Second Amended Credit Facility is restricted to the borrowing base, which is reserve-based and subject to semi-annual redeterminations on April 1 and October 1 of each year. On April 13, 2015, we entered into our third amendment to the Second Amended Credit Facility, which extended the maturity date of the Second Amended Credit Facility to April 13, 2020, provided that the 2019 Notes are retired or refinanced 90 days prior to the maturity of the 2019 Notes. In connection with this amendment, the lenders under our Second Amended Credit Facility (the “Lenders”) completed their regular semi-annual redetermination of the borrowing base scheduled for April 1, 2015, resulting in a decrease to the borrowing base from $2,000.0 million to $1,700.0 million . We increased the Lenders’ aggregate elected commitment from $1,500.0 million to $1,525.0 million . The overall senior secured line of credit under our Second Amended Credit Facility is $2,500.0 million as of June 30, 2015 .

Borrowings under our Second Amended Credit Facility are collateralized by perfected first priority liens and security interests on substantially all of our assets, including mortgage liens on oil and natural gas properties having at least 80% of the reserve value as determined by reserve reports. At our election, interest is generally determined by reference to (i) the London interbank offered rate (“LIBOR”) plus an applicable margin between 1.50% and 2.50% per annum; or (ii) a domestic bank prime rate plus an applicable margin between 0.00% and 1.00% per annum.

As of June 30, 2015 , we had $155.0 million of borrowings and $5.2 million outstanding letters of credit under our Second Amended Credit Facility, resulting in an unused borrowing base committed capacity of $1,364.8 million .

The Second Amended Credit Facility also contains certain financial covenants and customary events of default. If an event of default occurs and is continuing, the Lenders may declare all amounts outstanding under our Second Amended Credit Facility to be immediately due and payable. As of June 30, 2015 , we were in compliance with the financial covenants of our Second Amended Credit Facility. While we expect to draw on the Second Amended Credit Facility in 2015 to fund capital expenditures, we do not expect to violate any financial covenants.

Non-GAAP Financial Measures

Adjusted EBITDA and Adjusted Net Income are supplemental non-GAAP financial measures that are used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. These non-GAAP measures should not be considered in isolation or as a substitute for net income, operating income, net cash provided by operating activities or any other measures prepared under accounting principles generally accepted in the United States of America (“GAAP”). Because Adjusted EBITDA and Adjusted Net Income exclude some but not all items that affect net income and may vary among companies, the amounts presented may not be comparable to similar metrics of other companies.

Adjusted EBITDA

We define Adjusted EBITDA as earnings before interest expense, income taxes, depreciation, depletion, amortization, exploration expenses and other similar non-cash or non-recurring charges. Adjusted EBITDA is not a measure of net income or cash flows as determined by GAAP. Management believes that the presentation of Adjusted EBITDA provides useful additional information to investors and analysts for assessing our results of operations and our ability to incur and service debt and to fund capital expenditures.

Adjusted Net Income

We define Adjusted Net Income as net income after adjusting first for (1) the impact of certain non-cash and non-recurring items, including non-cash changes in the fair value of derivative instruments, impairment of oil and gas properties and other similar non-cash and non-recurring charges, and then (2) the non-cash and non-recurring items’ impact on taxes based on our effective tax rate in the same period. Adjusted Net Income is not a measure of net income as determined by GAAP. We define Adjusted Diluted Earnings Per Share as Adjusted Net Income divided by diluted weighted average shares outstanding. Management believes that the presentation of Adjusted Net Income and Adjusted Diluted Earnings Per Share provides useful additional information to investors and analysts for evaluating our operational trends and performance.

Fair Value of Financial Instruments

See Note 5 to our unaudited condensed consolidated financial statements for a discussion of our money market funds and derivative instruments and their related fair value measurements. See also Item 3. “Quantitative and Qualitative Disclosures About Market Risk” below.

Critical Accounting Policies and Estimates

There have been no material changes in our critical accounting policies and estimates from those disclosed in our 2014 Annual Report.

Recent accounting pronouncements

Revenue recognition. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The objective of ASU 2014-09 is greater consistency and comparability across industries by using a five-step model to recognize revenue from customer contracts. ASU 2014-09 also contains some new disclosure requirements under GAAP and is effective for interim and annual reporting periods beginning after December 15, 2017. We are currently evaluating the effect that adopting this new guidance will have on our financial position, cash flows and results of operations.

Table of Contents

whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for interim and annual reporting periods beginning after December 15, 2016. We do not expect the adoption of this guidance to have a material impact on our financial position, cash flows or results of operations.

Extraordinary items. In January 2015, the FASB issued Accounting Standards Update No. 2015-01, Income Statement - Extraordinary and Unusual Items (“ASU 2015-01”). ASU 2015-01 removes the concept of extraordinary items from GAAP. Under existing guidance, an entity is required to separately disclose extraordinary items, net of tax, in the income statement after income from continuing operations if an event or transaction is of an unusual nature and occurs infrequently. This separate, net-of-tax presentation will no longer be allowed. ASU 2015-01 is effective for interim and annual reporting periods beginning after December 15, 2015. We do not expect the adoption of this guidance to have a material impact on our financial position, cash flows or results of operations.

Debt issuance costs. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of debt discount, but it does not affect the recognition or measurement of debt issuance costs. ASU 2015-03 is effective for interim and annual reporting periods beginning after December 15, 2015. We do not expect the adoption of this guidance to have a material impact on our financial position, cash flows or results of operations.

Off-Balance Sheet Arrangements

Currently, we do not have any off-balance sheet arrangements as defined by the SEC. In the ordinary course of business, we enter into various commitment agreements and other contractual obligations, some of which are not recognized in our consolidated financial statements in accordance with GAAP. See Note 14 to our unaudited condensed consolidated financial statements for a description of our commitments and contingencies.

Table of Contents

Item 3. — Quantitative and Qualitative Disclosures About Market Risk

The following market risk disclosures should be read in conjunction with the quantitative and qualitative disclosures about market risk contained in our 2014 Annual Report, as well as with the unaudited condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q.

We are exposed to a variety of market risks including commodity price risk, interest rate risk and counterparty and customer risk. We address these risks through a program of risk management, including the use of derivative instruments.

Commodity price exposure risk. We are exposed to market risk as the prices of oil and natural gas fluctuate as a result of changes in supply and demand and other factors. To partially reduce price risk caused by these market fluctuations, we have entered into derivative instruments in the past and expect to enter into derivative instruments in the future to cover a significant portion of our future production.

We utilize derivative financial instruments to manage risks related to changes in oil prices. As of June 30, 2015 , we utilized two-way costless collar options, swaps and deferred premium puts to reduce the volatility of oil prices on a significant portion of our future expected oil production. A two-way collar is a combination of options: a sold call and a purchased put. The purchased put establishes a minimum price (floor) and the sold call establishes a maximum price (ceiling) we will receive for the volumes under contract. A swap is a sold call and a purchased put established at the same price (both ceiling and floor). For the deferred premium puts, we agree to pay a premium to the counterparty at the time of settlement. At settlement, if WTI is below the floor price of the put, we receive the difference between the floor price and WTI multiplied by the contract volumes, less the premium. If WTI settles at or above the floor price of the put, we pay only the premium.

We recognize all derivative instruments at fair value. The credit standing of our counterparties is analyzed and factored into the fair value amounts recognized on the balance sheet. Derivative assets and liabilities arising from our derivative contracts with the same counterparty are also reported on a net basis, as all counterparty contracts provide for net settlement.

The following is a summary of our derivative contracts as of June 30, 2015 :



									Weighted Average Deferred Premium
Settlement Period	Derivative Instrument	Total Notional Amount of Oil	Weighted Average Prices								Fair Value Asset
Settlement Period	Derivative Instrument	Total Notional Amount of Oil	Swap		Floor		Ceiling				Fair Value Asset
		(Barrels)	($/Barrel)								(In thousands)
2015	Two-way collars	975,000			$	86.25	$	103.15			$	25,462
2015	Swaps	4,089,000	$	75.76							63,667
2015	Deferred premium puts	180,000			$	90.00			$	2.55	5,201
2016	Two-way collars	155,000			$	86.00	$	103.42			3,874
2016	Swaps	2,628,000	$	66.08							11,510
2017	Swaps	93,000	$	63.94							105
											$	109,819

Interest rate risk. We had (i) $400.0 million of senior unsecured notes at a fixed cash interest rate of 7.25% per annum, (ii) $400.0 million of senior unsecured notes at a fixed cash interest rate of 6.5% per annum and (iii) $1,400.0 million of senior unsecured notes at a fixed cash interest rate of 6.875% per annum outstanding at June 30, 2015 . At June 30, 2015 , we had $155.0 million of borrowings and $5.2 million letters of credit outstanding under our Second Amended Credit Facility, which were subject to varying rates of interest based on (1) the total outstanding borrowings (including the value of all outstanding letters of credit) in relation to the borrowing base and (2) whether the loan is a LIBOR loan or a domestic bank prime interest rate loan (defined in the Second Amended Credit Facility as an Alternate Based Rate or “ABR” loan). At June 30, 2015 , the outstanding borrowings under our Second Amended Credit Facility bore interest at LIBOR plus a 1.5% margin. We do not currently, but may in the future, utilize interest rate derivatives to alter interest rate exposure in an attempt to reduce interest rate expense related to debt issued under our Second Amended Credit Facility. Interest rate derivatives would be used solely to modify interest rate exposure and not to modify the overall leverage of the debt portfolio.

Counterparty and customer credit risk. Joint interest receivables arise from billing entities which own partial interest in the wells we operate. These entities participate in our wells primarily based on their ownership in leases on which we choose to drill. We have limited ability to control participation in our wells. We are also subject to credit risk due to concentration of our oil and natural gas receivables with several significant customers. The inability or failure of our significant customers to meet their obligations to us or their insolvency or liquidation may adversely affect our financial results. In addition, our oil and natural gas derivative arrangements expose us to credit risk in the event of nonperformance by counterparties. However, in order to mitigate the risk of nonperformance, we only enter into derivative contracts with counterparties that are high credit-quality financial institutions, most of which are lenders under our Second Amended Credit Facility. This risk is also managed

Table of Contents

by spreading our derivative exposure across several institutions and limiting the hedged volumes placed under individual contracts.

While we do not require all of our customers to post collateral and we do not have a formal process in place to evaluate and assess the credit standing of our significant customers for oil and natural gas receivables and the counterparties on our derivative instruments, we do evaluate the credit standing of such counterparties as we deem appropriate under the circumstances. This evaluation may include reviewing a counterparty’s credit rating, latest financial information and, in the case of a customer with which we have receivables, their historical payment record, the financial ability of the customer’s parent company to make payment if the customer cannot and undertaking the due diligence necessary to determine credit terms and credit limits. Several of our significant customers for oil and natural gas receivables have a credit rating below investment grade or do not have rated debt securities. In these circumstances, we have considered the lack of investment grade credit rating in addition to the other factors described above.

We may, from time to time, purchase commercial paper instruments from high credit quality counterparties. These counterparties may include issuers in a variety of industries including the domestic and foreign financial sector. Our investment policy requires that our counterparties have minimum credit ratings thresholds and provides maximum counterparty exposure values. Although we do not anticipate any of our commercial paper issuers being unable to pay us upon maturity, we take a risk in purchasing the commercial paper instruments available in the marketplace. If a commercial paper issuer is unable to return investment proceeds to us at the maturity date, it could take a significant amount of time to recover all or a portion of the assets originally invested. Our commercial paper balance was $36,000 at June 30, 2015 .

Most of the counterparties on our derivative instruments currently in place are Lenders under our Second Amended Credit Facility with investment grade ratings. We are likely to enter into future derivative instruments with these or other Lenders under our Second Amended Credit Facility, which also carry investment grade ratings. Furthermore, the agreements with each of the counterparties on our derivative instruments contain netting provisions. As a result of these netting provisions, our maximum amount of loss due to credit risk is limited to the net amounts due to and from the counterparties under the derivative contracts. We had a net derivative asset position of $109.8 million at June 30, 2015 .

Item 4. — Controls and Procedures

Evaluation of disclosure controls and procedures. As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”), our principal executive officer; Chief Financial Officer (“CFO”), our principal financial officer; and Chief Accounting Officer (“CAO”), the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2015 . Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our CEO, CFO and CAO as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our CEO, CFO and CAO have concluded that our disclosure controls and procedures were effective at June 30, 2015 .

Changes in internal control over financial reporting. There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the three months ended June 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
